Parameters for apple quality and an outline for a new concept of quality
Provedor de dados: 21
Autores: Huber, Machteld.
This report was presented at the UK Organic Research 2002 Conference. The commonly used concept of quality in relation to
food, with its emphasis on external appearance and nutritional content is not sufficient for organic products and their market. In
response a quality concept known as ‘vital quality’ has been developed based on the life processes (growth and differentiation)
and corresponding product attributes (vitality,
structure and coherence). The research project presented is based on the
evaluation of the quality of apples, specifically cultivated for the research project with variation in picking date, bearing, sun
exposure, bio-dynamic preparations and ageing after storage. Quality measurements included traditional methods used...

Quality and Competition: An Empirical Analysis across Industries
Provedor de dados: 31
Autores: Crespi,
John M.; Marette,
Stephan.
This paper empirically explores the link between quality and concentration in a cross-section of manufactured goods. Using
concentration data and product quality indicators, an ordered probit estimation explores the impact of concentration on quality that
is defined as an index of quality characteristics. The results demonstrate that market concentration and quality are positively
correlated across different industries. When industry concentration increases, the likelihood of the product being higher quality
increases and the likelihood of observing a lower quality decreases.

Food Quality Strategies for enhancing organic food quality
Provedor de dados: 21
Autores: Stopes, Christopher.
This Research Topic Review aims to summarise the available knowledge on strategies for enhancing organic food quality. The
Review will provide organic advisers with a better understanding of the differences between organic and conventional food
quality so that they can support the development of organic farming systems and supply chains that deliver better quality organic
food. The Review takes a broad definition of food quality and on the appropriate methods for determining food quality. However,
the focus is on the factors that are more or less within the control of the farmer and the rest of the supply chain, and that directly
impact on the appreciation or the intrinsic quality of the food as presented to, and eaten by the consumer.

In terms of the working quality of agricultural production and the working quality of non-agricultural production, the evaluation
index system of the working quality of farmers is established. By using integrated furry method based on AHP, we determine the
weight of each index, and establish membership matrix of this evaluation index system. Taking Jilin Province as an example, we
select developed regions, underdeveloped regions and comparatively developed regions respectively to conduct survey. By using
the data from survey, according to the established evaluation index system, we conduct empirical analysis of the working quality
of farmers. The results show that the working quality of farmers in the developed regions is relatively high, the working...

The present study had as major objective to analyze the implementation process of the coffee quality program (CQP) and its
implications on the roasted and ground coffee companies in Brazil. Firstly, the philosophy and the objectives of CQP were
described in the construction of a theoretical analysis model, the “quality pillars”. The marketing strategies of thirteen roasters
were analyzed. Research data were analyzed with the support of the “quality pillars” model: product quality, process quality, and
the quality signal. As main results, it was possible to imply that quality was the main factor that increased the vertical coordination
between the researched companies. Therefore, CQP implementation leads companies to the adoption of vertical coordination...

A MODEL OF THE IMPLEMENTATION OF QUALITY MANAGEMENT SYSTEMS FOR
CREDENCE ATTRIBUTES
Provedor de dados: 31
Autores: Noelke,
Corinna M.; Caswell,
Julie A.
We develop a model of the impact of food quality management systems (QMS) on competitiveness and markets. QMS seek to
control the quality of a product as determined by the array of individual attributes it possesses. To date only a few studies have
attempted to better understand the effect of the introduction of quality management systems. No model has been introduced
which captures the interactions within the supply chain and at the interface with consumers when these systems are introduced.

Enhancing and testing soil quality
Provedor de dados: 21
At present, soil fertility testing is based on soil chemical analysis. Organic amendments, either as manure and compost or residue
from preceding crops and green manure, are essential for maintaining and enhancing soil quality and nutrient management in
organic farming. Thus, organic farming is dependent on biologically mediated processes and functions of the whole soil system.
Soil quality can be defined as soil's ability to function, it is dependent on the purpose of soil use, and it is based on chemical,
physical, and biological soil properties. In recent years, there has been increasing interest in soil quality estimations. The aim of
the study is to develop a soil quality test applicable for both organic and conventional farming. To achieve this, the...

The Inner Quality Concept for food, based on life processes
Provedor de dados: 21
Autores: Bloksma, J.; Huber, M.; Northolt, M.; van der Burgt, G.J.; Adriaansen-Tennekens, R.
How can we adequately express the quality of food produced by organic agriculture? To answer this research question, we defined
a concept of ‘inner quality’ (formerly called ‘vital quality’) based on the life processes growth and differentiation, and their
integration. Growers use management methods to influence life processes in their crops, thus optimising the quality of the final
product. Traders and consumers can recognise certain product properties as being the result of these life processes. Here, we
present a course of validation for the quality concept, together with appropriate quality parameters. The process of validation has
been completed in part for two experimental crops, apple and carrot. This quality concept can provide a holistic context...

The value of quality
Provedor de dados: 31
Autores: Nabradi,
Andras.
The significance of quality production and quality improvement is widely acknowledged by many but few specify what should be
improved and what quality should be produced. The reason may be that there are different quality categories in the process of the
value chain. Moreover, the issue of quality costs, i.e. economically optimal quality has not yet been explored yet. The present
study raises problems in the pigmeat verticum, but similar studies are needed in other animal husbandry sectors as well. It is
reasonable to treat the quality categories of animal products in a complex way, as this allows the full satisfaction of consumer
expectations at the certain stages of the value chain and solvent demand as well.

In order to ensure and to improve quality in the agro-food sector quality systems have to undergo a permanent change: simple
end-of-the-pipe monitoring is therefore being replaced with management oriented concepts. Farmers are also increasingly
requested to implement quality systems. This paper gives an overview of quality regimes in the agro-food sector and compares
three systems in the domains of pork production, potato growing and the cultivation of hop. 315 Bavarian farmers were
interviewed in order to identify factors which may influence the satisfaction with quality systems. Differences between the three
quality regimes were moderate with respect to the overall satisfaction. Hop growers judged their system to improve production
efficiency while the...

The consumer has the final word in food choice, which is determined by his perceived quality. Within a project coordinated by the
Faculty of Veterinary Medicine we tried to relate objective quality with the consumer quality evaluation. To do so, we have
measured the expected and experienced quality of a sample of Portuguese consumers towards three types of beef (PDO, national
and imported) at the shop, and compared this subjective evaluation with the beef objective quality. Results at the consumer level
show that respondents perceived PDO beef to be of higher quality than the two other types of beef for different attributes and for
overall quality at the shop location. In terms of objective quality results, the three types of beef showed highly similar...

The Quality Index: A holistic Approach to describe Quality of Food
Provedor de dados: 21
Autores: Schulz, D.G.; Köpke, U.
Adequately assessing the quality of food grown with different cultivation methods is a constant problem. According to
SCHUPHAN (1961), food quality consists of three main characteristics: grading, technological quality and nutritional quality. The
latter involves the ratio between beneficial and harmful substances. Yet it is obvious that more than merely summing various
substances is needed to assess the quality of food properly. This problem has been previously discussed by SCHORMÜLLER
(1974) and KLETT (1968). A concept of quality that embraces the plant as a whole (and the internal equilibrium of the individual
components) requires bringing together the results of multiple investigations in an integrated accounting that registers even

Product Quality in the Food Chain: Do Cooperatives Offer High Quality Products?

Autores: Pennerstorfer,
Dieter; Weiss,
Christoph R.
Cooperatives and investor-owned firms are alternative forms of business organisation that coexist and compete in many markets.
The theoretical literature has identified a number of comparative advantages and disadvantages of cooperatives. Decentralized
decision making within cooperatives may lead to quality coordination problems (free-riding on product quality), for example:
whereas the individual member has to bear the full costs associated with higher quality, the benefits of delivering higher quality
will be shared among all members. The present paper investigates this free-riding problem in determining product quality within a
marketing cooperative in a vertically related market (food chain). On the basis of a mixed-oligopoly model, we show that the...

The present paper investigates the free-riding problem in determining product quality within cooperatives in a vertically related
market. Whereas the individual member has to bear all costs associated with higher quality, the benefits of delivering higher
quality have to be shared among all members. On the basis of a Mixed-Oligopoly model, we show that the free-rider problem in
the supply of high-quality products, although important for the members of the cooperative, may not be strong enough to ensure
that firms will always supply higher quality than cooperatives. Whether the cooperative can overcome the free-riding problem and
supply a final product of high quality is shown to depend on the consumer'’s valuation of quality, the costs of producing high...

We investigate the impact of decentralised decision making on product quality. Comparing a cooperative (decentralized decision
making) and a firm (centralized decision making) suggests that members of the cooperative have an incentive to produce too
much and to free-ride on quality. Free-riding on quantity and quality are interrelated which implies that the final product of the
cooperative can even be of higher quality than its entrepreneurial twin, despite free-riding on quality. Whether or not cooperatives
deliver higher quality products depends on the way in which the quality of the final product is determined from the quality levels
of the inputs delivered (quality aggregation) as well as the number of members of the cooperative. Empirical evidence on...

Hordein polypeptide patterns in relation to malting quality in Brazilian barley varieties
Provedor de dados: 86
Autores: Echart-Almeida,Cinara; Cavalli-Molina,Suzana.
Since there is evidence that malting quality is related to the storage protein (hordein) fraction, in the present work the hordein
polypeptide patterns from 13 barley (Hordeum vulgare L.) varieties of different malting quality were analysed in order to explore
the feasibility of using hordein electrophoresis to assist in the selection of malting barleys. The formation of clusters separating the
varieties with higher malting quality from the others with lower quality suggests that there is a relationship between the general
hordein polypeptide pattern and malting quality in the varieties analysed. By the Sperman's correlation test three hordein bands
correlated negatively with malting quality in the germplasm studied.

Does Product Diversity Signal Bargains in Australian Wine?
Provedor de dados: 31
Autores: Horowitz,
Ira; Lockshin,
Larry.
The residuals from a set of linear regression equations built to explain the quality of a bottle of Australian wine via eight quality
signals are examined to determine whether there is any relationship between their signs for individual producers and the diversity
of their offerings. Product diversity is found to be a fault-ridden signal of a quality-bargain, which we define as a bottle of wine
whose quality rating exceeds its regression-based expectation. Indeed, to the extent that the signal does impart useful information,
the message would be that consumers are less likely to get their money's worth the greater is the diversity of the producer's
offerings.

Domestic tobacco producers have faced increasing competition from imported tobacco since the late 1970s. Much of the debate
has centered on the unknown quality of imported tobacco. This study provides a discussion and clarification of the concept of
quality, and demonstrates a method of measuring the average quality of imported tobacco. The results show that since 1977,
imported tobacco has been steadily decreasing in average quality and moving toward lower quality producing countries and types
of tobacco. The reasons for this decline are discussed along with the policy implications.

The quality requirements that consumers consider in their decision to purchase fresh fruit have garnered a great deal of attention
from the actors in the fresh fruit productivity chain. This study seeks to identify attributes that could explain how a consumer of
fresh peaches perceives quality. The focus on the peach was because of the limited knowledge of the signs of quality that the
consumer is seeking in this fruit. As a result, the objective was to produce a model that explains the perception of the quality of
fresh peaches by Spanish consumers. A theoretical model was created that explains quality using a set of intrinsic and extrinsic
attributes. The information was from a survey of closed questions administered in person to a non-probabilistic...

Autores: Konvalina, Petr; Moudry, Jan (Jr.); Capouchova, Ivana; Moudry, Jan.
The technological value of wheat is negatively influenced by organic methods of cultivation. The critical factor is the crude
protein content and quality. The aim of this paper is to identify diferences in the quality of eight varieties and two strains of wheat
recommended in conventional or organic conditions. Correlation analysis of the qualitative parameters of wheat shows a clear
relationship between crude protein content, wet gluten content and Zeleny - sedimentation value. According to the test results, it is
appropriate to use the content and quality of protein as selective criteria for the selection of varieties. The Level of baking quality
is never reduced below the quality level of the worstquality varieties grown in the same conditions. On the...

At the Louis Bolk Institute, together with several international partners, years of work and several research projects were directed
towards the validation of the "Inner Quality Concept"; an organic food quality concept. This concept intends to build two bridges.
One bridge between crop management and food quality and another bridge between food quality and possible health effects for
the consumer. This paper focuses on requirements for validating a concept, presenting examples from the work in the Louis Bolk

The European Policy for Food Quality and the Fischler’s Reform
Provedor de dados: 31
Autores: Carbone,
Anna; Sorrentino,
Alessandro.
Fischler’s Reform of the Cap has introduced economic support to reinforce the range of instruments aimed at promoting food
quality. Before the Reform, European Union market intervention for food quality was confined to the regulatory ground. The
paper discusses the economic justifications for financial aid in the case of quality improvement and in the case of information
circulation and provision of assurance to consumers. The possibility to add new Quality Schemes at the existing ones is criticized
because of the information overcrowding. Furthermore, it is argued that a ’race to the bottom’ mechanism could be enforced as
a result of the introduction of the possibility to settle Quality Schemes on a national basis. The paper also shows that the...

Consumers’ quality judgement depends on their knowledge concerning certain quality attributes. Against this background this
paper presents the results of a consumer survey conducted in 2004. We focus on measuring consumers’ cognitive structures
regarding pork and potatoes. On this account we apply a free-association technique and a variation of concept mapping. Our
analysis shows that consumers’ cognitive structures are quite complex and heterogeneous. Product characteristics such as ‘taste’
and ‘fat content’ dominate consumers’ knowledge. To predict the eating quality of pork consumers prefer intrinsic quality cues. In
contrast to that extrinsic quality cues are used to predict the origin of the given product. With regard to potatoes the intrinsic

Lack of Credibility in Food Markets - Driving Medium Quality Food Out of the Market
Provedor de dados: 31
Autores: Christensen,
Jan; Graversen,
Jesper T.
Some food markets are dominated by high quality and standard quality segments, whereas medium quality products are almost
absent. A modeling framework with asymmetric information regarding true quality of the products and the resulting lack of
consumer confidence is presented. Uncertainty regarding the quality of alleged medium quality products provides certain
consumer groups to divert consumptions away from medium quality to either standard or high quality products. These
countervailing incentives explain the missing medium quality products. Empirical examples are given to motivate the model.

Based on accepted advances in the marketing, economics, consumer behavior, and satisfaction literatures, we develop a
micro-foundations model of a firm that needs to manage the quality of a product that is inherently heterogeneous in the presence
of varying customer tastes or expectations for quality. Our model blends elements of the returns to quality, customer lifetime
value, and service profit chain approaches to marketing. The model is then used to explain several empirical results pertaining to
the marketing literature by explicitly articulating the trade-offs between customer satisfaction and costs (including opportunity
costs) of quality. In this environment firms will find it optimal to allow some customers to go unsatisfied. We show that the...

For many agricultural products, the quality of the final products strongly depends on different stages of the productive chain. This
stresses the importance of relationships between quality signal owners and suppliers in the vertical chain. Based on a New
Institutional Economics analysis, the goal of this paper is twofold: (i) to design a framework to study the links between quality
signaling, coordination in the supply chains and the institutional environment, (ii) to conduct a comparative analysis to identify,
compare and explain the modes of organization implemented for the governance of different quality signs. The general hypothesis
is that, in order to assure the credibility of a quality signal, there must be an efficient alignment between quality...

Quality and quality assurance are among the most critical issues facing the fresh produce industry. This paper shows that while
quality is widely noted to be an important concept, it is not clearly defined in the literature. Several definitions of quality are
presented. The terminology associated with quality assurance is analyzed. An array of quality assurance systems used in the
European fresh product sector are presented. Conclusions are drawn that while fresh produce quality will always be a factor
retailers use to compete for consumers, there is evidence of industry consensus on some quality attributes, particularly, safety,
environmental, and social attributes.

As part of an economic survey of Maryland registered boat owners, an open ended contingent valuation question was posed
regarding willingness to pay for an improvement in water quality in Chesapeake Bay. The boaters ranked their perception of
water quality on a scale of one to five, and the payment was for an improvement of one unit. Boaters also indicated the type of
concern poor water quality raised, ranging from no concern to concern about long term effects of exposure to toxic chemicals.
Median willingness to pay for a one step improvement in water quality was $17.50 per year and the mean was $63, with 38%
expressing a zero willingness-to-pay.
A tobit model was estimated to determine what factors influenced willingness to pay

Nature quality in organic farming: A conceptual analysis of considerations and criteria in a European
context
Provedor de dados: 21
Autores: Tybirk, Knud; Alrøe, Hugo Fjelsted; Frederiksen, Pia.
Nature quality in relation to farming is a complex field. It involves different traditions and interests, different views of what nature
is, and different ways of valuing nature. Furthermore there is a general lack of empirical data on many aspects of nature quality in
the farmed landscape.
The present paper looks at nature quality from the perspective of organic farming, which has its own
values and goals in relation to nature – the "Ecologist View of Nature". This is in contrast to the "Culturist View" characteristic of
much conventional agriculture and the "Naturalist View" characteristic of the traditional biological approach to nature quality.
This threefold distinction forms a framework for exploration of nature quality criteria in the farmed...

Assessing impacts of organic production on pork and beef quality

Organic livestock farming is based on a low input production method, aiming to provide products of a high product and process
quality rather than maximizing production. The production of a high meat quality corresponds to the expectations of consumers
who are both seeking a premium product and who are willing to pay premium prices. This review focuses on the question of
whether organic pork and beef production currently meet consumer demands, and it elaborates the potentials and limitations for
producing high-quality meats under the current organic framework.
Although defined by specific and basic guidelines, organic
livestock production is characterised by largely heterogeneous farming conditions that allow for huge differences in the

One of the major problems in the Brazilian agriculture is related to the production loss in the field, which, due to many factors, is
not being considered. This article has the objective to develop a methodology to identify a quality index which integrates some
crop quality variables which are able to indicate how the crop is developing in terms of loss in the field. The results have showed
that the strategy of multi-criterion analysis and Fuzzy logic proved to be important tools for the assessment and preparation of a
quality index for corn production. The index proposed performed well in representing the quality of agricultural operations when

This paper revisits the issue of the regulatory choice between a mandatory label and a minimum-quality standard. When the cost
of regulation is relatively low, we show that the socially optimal choice depends on the producers' cost structure for complying
with regulation and improving quality. Under a marginal cost for improving quality, the mandatory labeling is sufficient for
reaching the socially optimal level of quality. Under a fixed cost for improving quality, we show that each instrument or the
combination of both instruments may emerge at the equilibrium.

particularly those caused by dietary protein to energy ratio. Rigor mortis follow-up studies showed that there are no losses in meat
quality when carcasses are hot-deboned. Age at slaughter influences some meat quality traits, such as tenderness and lipid content.
Few effects of gender have been observed, and at the same age at slaughter, both male and female present the same meat quality

Food quality from a consumer perspective includes sanitary aspects as well as nutrition, but also taste, aspect, integrity and the
particularity of products. But quality at the consumer level can only be achieved if quality is respected throughout the whole
chain. An analysis is undertaken using as a case study Portuguese producers of two types of PDO beef. Results, using multivariate
data analysis, show that the main attributes for a quality beef at the producers` level are: feeding, finishing, specific quality, age at
slaughter, breed and transport. Results also suggest that producers have distinct quality perceptions on PDO beef.

agricultural production and water quality are relevant, but measuring the off-farm benefits and costs of changing water quality is
difficult. Many of the values placed on these resources are not measured in traditional ways through market prices. This report
explores the use of nonmarket valuation methods to estimate the benefits of protecting or improving rural water...

Quality Management in Supply Chain Networks - The Case of Poland
Provedor de dados: 31
Autores: Hanf,
Jon Henrich; Pieniadz,
Agata.
In this article we suggest that rising quality requirements are key factors for the redesign of food chains. We argue that the food
supply proceeds through pyramidalhierarchical strategic networks coordinated by powerful focal firms. These firms choose a
quality strategy and employ chain quality management concepts by exerting managerial discretion to achieve the super-ordinate
network aims. We introduce and elaborate upon two types of chain quality management: strategic and operative. The theoretical
findings have been tested using evidence from the Polish dairy market. Semi-structured interviews were conducted across the
various hierarchical levels of the 19 largest Polish dairy cooperatives during the spring of 2006. The results show that the firms’...

It is widely acknowledged that competition is no longer between individual firms, but between supply chains. A number of studies
have indicated that supply chain integration and quality management have become essential to obtain competitive advantage. The
present study tests the relationships among supply chain integration, quality management practices and firm performance in 229
Chinese pork slaughterhouses and processors using structural equation modeling. The most important results are that quality
management is positively linked with firm performance. As managers put it "Quality is the life of the enterprise". Pork processing
managers that wish to improve their performance are therefore advised to invest in quality management. Equally interesting is...

Modeling Beef Quality Heterogeneity

The effects of various supply and demand shifts on beef price, quantity, and industry welfare have been widely studied under the
assumption of beef quality homogeneity. In this paper, we construct a model of the beef sector that incorporates differences in
beef quality. The model is used to analyze the effect of supply and demand shifts on changes in prices and quantities of high-and
low-quality beef and changes in revenue accruing to producers of high-and low-quality beef. Model results indicate that supply
and demand shocks have the potential to alter the average quality of beef on the market and the price premium charged for
high-quality beef, which has important implications for retailers selling quality-differentiated beef and producers selling...

Food quality has become an important determinant of success in global food trade and growers for international markets have to
continuously adjust to buyers’ requirements. It is however not clear to what extent there is a demand for food quality - and how
much buyers are willing to pay for it - in the domestic food markets of developing economies. Based on unique price and trader
data from domestic food markets in a poor country in Africa (Madagascar) and an emerging economy in Asia (India), we compare
quality and quality’s pricing. We find significantly better quality and higher quality premia (using revealed as well as stated
preference methods) in the richer country, probably leading to an impetus for the development of modern market channels in

Autores: Marchesini,

Domenico.
Consumers look for the highest affordable food quality, given their household budgets and perceptions of product quality. Such
perception is however strictly related to culturally linked variables, and the importance attached to each component of the overall
quality vary greatly among countries. Different perceptions lead to different purchase decisions. This concept is even clearer for
the aspects of quality that can’t be tested directly. Consumer goods may be divided into search, experience and credence goods,
depending on when the consumer is capable of assessing their quality (before buying, after consuming or in the very long term).
Most quality agro-food products, such as food with geographical indications (GIs) and low input food (LIFs), fall into...

Impact of Beef Quality on Market Signals Transmitted by Grid Pricing
Provedor de dados: 31
Autores: Johnson,
Heather C.; Ward,
Clement E.
Value-based marketing is shaping cattle production; however, market signals differ dramatically depending on carcass quality.
This study applies a two-stage coefficients of separate determination procedure to four regional fed cattle datasets sorted by grid
value and by carcass quality attributes. Weight is the strongest signal sent when higher valued cattle and better quality cattle are
sold on a grid. Quality characteristics send stronger signals when lower valued cattle and poorer quality cattle are sold on a grid.
Producers of lower quality cattle can potentially gain $52 to $149 per head by improving quality and $113 to $150 per head by
adding weight.

Autores: Baracho,MS; Camargo,GA; Lima,AMC; Mentem,JF; Moura,DJ; Moreira,J; Nääs,IA.
Poultry meat quality has been widely studied, and has become a growing demand of the international market. Parameters that
affect meat quality are complex, and occur throughout the production chain. The constant concern with meat quality by the
exporting sectors is a response to consumers' demands, and is achieved by increasing efficiency, and investments in personnel
training on quality. Understanding where critical points are in the poultry meat production chain, and investing in solving critical
problems may lead to better control and management, and consequent reduction of losses. Production and management practices,
from farm to processing plant, play an important role in meat quality, and the use of technologies to reduce risk factors throughout

The soil quality concept and its importance in the study of Finnish arable soils
Provedor de dados: 21
Autores: Palojärvi, Ansa; Nuutinen, Visa.
Arable soil is a functional unit whose condition is vital to crop production, but also to ecosystems at large owing to the significant
role of soil in global nutrient cycles and balances. The soil quality concept recognises the concern for the sustainability of current
arable land use practices. It integrates soil chemical, physical and biological properties, and takes account of the interaction of soil
with water and air. This paper reviews the soil quality concept and its applications and discusses the importance of the concept for
the assessment of Finnish arable soils. Many aspects of the chemical quality of arable soil are already well known in Finland. In

In real life it is hard to distinguish between the two life processes, growth and differentiation. We cannot expect one measured
parameter to represent only one aspect of vital quality. But for most parameters we can recognise emphases on one or more
aspects of the vital quality concept. We made this prelimary classification both by thinking about the concept and by looking at
the experimental results. Also the conventional parameters are interpreted as a result of these processes in a more holistic way
than usual. We realise that various parameters all concerning the same aspect of our quality concept can show different levels of
the aspect. To belong to the same aspect of the quality concept does not automatically mean that their correlation (see annex...

Autores: Marian, Livia; Thøgersen, John; Krystallis Krontallis, Athanasios.
The hypothesis of this research is that the impact of quality dimensions on consumers’ willingness to buy organic vs. conventional

followed by a questionnaire containing a conjoint analysis design. The purpose of the focus groups was to determine the most
important quality cues, which could afterwards be incorporated into the choice experiment. It was found that production method,
price, size and information about farmer and rearing conditions are very important quality cues for the choice of chicken, and that
taste is one of the most important quality dimensions in consumers’ overall evaluation of chicken. In the next step, the...

life and quality of work life are two indicators very related to the viability and sustainability of farms. They are located into the
social sustainability but in some cases the production system affects all three aspects of sustainability and transcends into a
lifestyle. Organic production in several small ruminant farms analyzed in Spain provides quality of life and quality of work

In spite of variable grain protein contents, baking quality of organic wheat was found to be acceptable to good. Mycotoxin (DON)
infestation was generally low on tested grain samples. Choice of wheat cultivar was the most efficient way to obtain higher grain

We analyze quality differences in market hogs across alternative procurement methods. The test results show that alternative
marketing (procurement) channels generate hogs of statistically different quality. However, the quality ordering of alternative
marketing arrangements is not unique, but varies across quality attributes, and the quality differences do not appear to be
economically significant. We examine the relationship between alternative procurement methods for live hogs and the quality of
the resulting pork products. The correlation coefficient between the non-spot market purchases of live hogs and the Hicks’
composite quality index for pork products is positive and significant, but the magnitude of that effect is small. Finally, we show

Quality management is of paramount importance in all stages of the Agri-Food production and process chain. The approach of
quality management has been changed in the past years due to the effects of globalization, numerous deficits in food safety and
the legislative such as the new European regulation 178/2002 concerning food safeties. A trend, which can be shown, is the
development of several quality systems and norms in response to this challenge. Therefore programmes will be developed and
improved in the Agri-Food-industry further on. There are general quality systems, which are applied in different countries and
sectors, country and product specific standards and programmes, which were developed by retail initiatives. This paper will give

This research examines the factors behind price differentials based on regional origin. For this purpose, we estimate a hedonic

expert opinions about sensory quality, maturing potential, and special selections as well as derived indicators that signal a high or
low quality producer. After correcting for variety, regional origin, and age, the data confirms that a wine's price is related to
producer quality signals, which may even negate regional effects. We conclude that it is problematic to interpret regional

This report provides a new economic approach and methodology for analyzing nutritional quality change in manufacturers' food
product offerings and food products purchased using a case study of five food product categories in the mid-1990's. Two
approaches were used to analyze nutritional quality change in product offerings. The first approach uses a composite nutritional
index to measure changes. A second approach, nutrient-by-nutrient analysis, was also used to measure quality change. Overall, the
nutrition index analysis showed no significant change in the average nutritional quality of products offered for sale in the five
categories.

As food quality becomes more complex, consumer s are tending to reduce their involvement in the food purchase decisionmaking process. Consequently, prices are becoming more significant as they represent an easy choice criterion when consumer s
have less information about the differences between the product and process quality inherent in food items (including
environmental or social issues). The organic food sector provides high, complex food quality profiles and has therefore been
seriously affected by this development. Consequently some SMEs in the food business sector are starting to emphasize certain
quality factors, such as sustainable production and processing, as a means of communicating their added value to consumer s.

quantity as goods, an optimal tax system would never reduce the quality marketed, though it necessarily reduces quantity. Any
two-tax system that includes a volumetric sales tax and any one of three other types of tax ’ an ad valorem sales tax, an ad

GOVERNMENT VERSUS PRIVATE QUALITY ASSURANCE FOR AUSTRALIAN FOOD
EXPORTS

Autores: Wills,
Ian R.; Harris,
Jane.
Most foodstuffs have quality attributes that are difficult to determine prior to purchase. Thus quality assurance is an inherent
problem in food exporting. Private quality assurance can succeed if exporters can credibly signal that they have much to lose from
cessation of purchases. If exporters do not provide credible quality signals, and foreign importers judge food quality according to
country of origin, honest exporters can suffer negative spillovers from others' cheating under either government or private quality
assurance. For both economic and political reasons, the best choice between government and private quality assurance will differ
between foods and importing countries.

A relative increase in demand for quality can have one of two potentially countervailing effects: it can cause substitution of one
quality for another and/or it might expand overall demand by bringing new consumers into the market. This article investigates
demand expansion and substitution among beef qualities by exploiting the use of a no-purchase option in a nonhypothetical choice
experiment involving real food and real money. A random parameters logit model, which permits very flexible substitution
patterns, is used to show that expanding demand for high quality rib-eye steak increases revenue by a greater degree than
expanding demand for low quality steak. Regardless of whether high or low quality demand is expanded, the expansion effect

In the early 1990s reform of the EU’s Common Agricultural Policy led to a change in emphasis away from price into policies to
promote rural development, in part through improvements to food quality. Geographic indicators are only one of a range of EU
policies designed to foster these goals. Geographic indicators are put within the context of the wider quality enhancement policies
that include quality assurance schemes and organic production. There appears to be considerable regional differences within the
EU when it comes to the use of the various quality-enhancing policies available. The member states of the EU can be grouped into
four different clusters, each characterized by a different quality policy strategy.

Quality Provision and Farmer Inclusion of Agricultural Cooperatives
Provedor de dados: 31
Autores: Yu,
Jianyu.
The paper aims to analyze the quality provision and inclusion of farmers by a farmer-owned cooperative (co-op) when it competes
with an investor-owned firm (IOF). A model of mixed oligopsonistic competition is developed to capture the endogenous
participation of farmers who are heterogeneous in their efficiency to provide quality. The results highlight an advantage of the
co-op: by imposing a similar quality standard to the one imposed by the IOF, the co-op may drive the IOF out of the market. Due
to this advantage, it is more likely that the co-op will set a high quality standard when the minimum quality standard is costly to
farmers. This advantage, however, may induce an inefficient outcome if providing a high quality product involves a high fixed
cost.

According to the Council Regulation (EC) No 1804/1999), organic livestock production is intended to ensure quality production
rather than maximising production. In organic pig production, the availability of limited amino acids is the first limiting factor and
the main reason why the performance capacity is clearly diminished compared to conventional production. In order to compensate
for the lower productivity, quality production is a conditio sine qua none. Possibilities to improve the quality of organic pork were

nature of water quality effects. This report reviews practical approaches and theoretical foundations for estimating the economic
value of changes in water quality to recreation, navigation, reservoirs, municipal water treatment and use, and roadside drainage
ditches.

Does Price Signal Quality? Strategic Implications of Price as a Signal of Quality for the Case of
Genetically Modified Food
Provedor de dados: 31
Autores: Hwang,
Yun Jae; Roe,
Brian E.; Teisl,
Mario F.
We add to the limited empirical literature on consumers' use of price as a quality signal by testing if the traditional
downward-sloping consumption-price relationship fails to hold for GM products using data collected from a nationally
representative mail survey featuring several hypothetical product choice scenarios. Statistical evidence is mixed across the three
products investigated but suggests that survey respondents use price as a signal of the quality of GM products. Implications for
firm strategy are discussed.

How do consumers use signals to assess quality?
Provedor de dados: 31
Autores: Gergaud,
Olivier; Livat,
Florine.
This article analyzes the way some 6,000 European wine consumers, both connoisseurs and non-connoisseurs, use a set of
available signals (price, umbrella branding, goodwill, past consumption) to assess the quality of Bordeaux wines where price is
the main source of information on quality. Connoisseurs use this signal less intensively than on connoisseurs. Price represents a
substitute for umbrella branding where consumers are not aware of who is beneath this umbrella, and where this signal is thus of
no help to them. This could explain why such wines tend nowadays to lose market share in favor of branded wines that are easier
to evaluate.

Autores: Fernandez-Olmos,
Marta; Rosell-Martinez,
Jorge; Espitia-Escuer,
Manuel Antonio.
We analyze the relationship between product quality and governance mode choice using the results of a survey of DOC Rioja
wineries. Wineries that produce high-quality wines are more likely to vertically integrate than are wineries that produce
low-quality wines. Consistent with Transaction Cost Economics, we find evidence that asset specificity and uncertainty are
important determinants of vertical integration. Finally, the size of the winery is also an important factor that affects governance
mode choice in viticulture.

This paper analyzes a monopolist's behavior when consumers cannot observe the production standards. These types of products
are usually known as credence goods. The steady-state level of quality with credence goods is found to be lower than that with
experience goods, and perfect information goods. The finding that only perceived quality, which is effectively a filtered version of
true quality, affects reputation indicates rewards for high quality production are lower in the credence good case. Further, an
increase in the level of monitoring can increase the true level of product quality in the market for credence goods.

The Role of Contract in Quality Assurance

In recent years a debate has raged about the accuracy of the cost-of-living index. A major bone of contention regards capturing the
changes in the quality of goods. Were it easy to measure quality, disputes about the magnitude of the change would have not
arisen. The difficulty in pinpointing quality is not merely an academic or policy question; it also poses a major problem for
exchange. When the quality of the exchanged commodities is uncertain, costly disputes about what one gives and the other
receives are bound to arise. Such disputes are a matter of property rights, of who owns what.

FORECASTING CROP QUALITY
Provedor de dados: 31
Autores: Ryland,
G.J.
The need for a forecasting system of biological quality arises as a result of the price-quality payment schemes in grower and
processor contracts which operate in many agricultural cropping industries. The seasonal nature of the series of vertical quality
height gives rise to questions as to the repetitive pattern of the shape and trend translation of the series. These hypotheses can be
tested using conventional statistical methods. For non-stationary series, however, a Box-Jenkins type dynamic seasonal model is
proposed. These forecasting procedures are applied to a series of sugar cane quality.

We examine the implications of health seeking behavior on access to quality health care using a unique dataset that combines a
household survey from rural Tanzania with the location and quality of all health facilities available to households. Patients do not
always visit the nearest facility, but choose from among multiple facilities, improving the quality of care they receive by
bypassing low quality facilities. Recognizing this behavior alters the projected benefits to health interventions, reducing the value
of focusing on the staff qualifications and increasing the value of focusing on travel time and the motivation of current staff.

This paper seeks to explore a survey of consumers in Spain. The survey explores the attributes of quality that consumers are
seeking and promotion of grapes via "quality" marks, which are indicators of possible ways to increase demand. The reason
consumers are switching to other foods, such as dairy based snacks, is that grapes are not easy to eat, can be unreliable in terms of
their quality attributes, and their price more variable. Consumers are also generally unaware of the marks quality currently used.

Intercropping legumes (grain or forage) improves weed competition and N availability for wheat crop or succeeding crop. Green
manure can be an effective alternative to farmyard manure. Fertilization with readily available nitrogen improves yield and quality
when water is available. Reduced tillage affects soil fertility and wheat yield but has little effects on grain quality.

Consideration of consumers' demand for food quality entails several aspects. Quality itself is a complex and dynamic concept, and
constantly evolving technical progress may cause changes in consumers' judgment of quality. To improve our understanding of
the factors influencing the demand for quality, food quality must be defined and measured from the consumer's perspective
(Cardello, 1995). The present analysis addresses the issue of food quality, focusing on pork-the food that respondents were

would pass on to producers only 70% of the quality-based price differentials received from next-in-line buyers. If competing
elevators also adopted these practices, profits for all elevators would return to near normal, and elevators would pass on to
producers nearly all price differentials received from next-in-line buyers. However, that research could not explain why more

REMI : French microbiological monitoring network for shellfish growing areas.
Provedor de dados: 5
Autores: Amouroux, Isabelle.
The microbiological monitoring and classification in Europe is based on faecal indicator E. coli monitoring in live bivalve
mollusc. As a result of the implementation of the microbiological threshold defined by European legislation since 01/01/2006,
almost all A quality areas have disappeared, and most areas show B quality. Percentage-wise, the C quality category is more
frequently observed for areas with burrowing bivalves like clams and cockles. From these results, a few elements can be pointed
out : - firstly : the contamination levels are different between the burrowing and non burrowing bivalves. Thus, it is important to
examine separately the evolution for each type of species. The evolution since 1989 shows for the oyster and mussels an...

Labeling policies and market behavior: quality standard and voluntary label adoption
Provedor de dados: 189
Autores: Bottega, L.; Delacote, P.; Ibanez, L.
This paper focus's on the third-party certifiers' strategy when choosing a required label quality, and the consequent market
outcome. We consider two different objectives of the certifier: maximizing global demand for the labeled product (wide public
policy), or maximizing global quality of the market (global quality policy). In a duopoly set up with firms bearing different costs
with respect to quality provision, firms always opt for differentiation strategies: only one adopts the label. However, the labeling
firm is not necessarily the most efficient one. In the case of a wide public policy, the efficient firm will produce labeled products
only if costs of labeling are sufficiently low. In the case of a global quality policy, the low cost firm will...

Targeting occasional buyers - the need for quality related communication approaches

Autores: Bodini, Antonella; Richter, Dr Toralf; Felder, Rudolf.
Occasional organic buyers often purchase selected organic food items according to perceived added value in terms of quality and
food safety issues or perceived additional ecological and social performances along the supply chain. They clearly take a more
critical view of organic food and the organic farming concept in general than regular buyers do (Richter et al., 2004; Zanoli,
2004). The main barrier preventing this group from expanding its consumption of organic food is the higher price, which, in their
perception, is not justified sufficiently by added quality attributes. However, in many cases the underlying problem is related to
the complexity of quality profiles which are less transparent and understandable. To tackle this issue, the paper...

The demand for high quality organic bread wheat is increasing. The quality level of organic wheat harvested in EU is mainly
dependant on variety, environmental conditions and agronomic practices. In some countries, protein content and composition,
influencing technological value, are equivalent to those produced under conventional practices. Beside agronomical techniques,
technological processes can help to maintain a good quality. Pre-treatments before milling such as debranning were found to be
efficient in reducing DON contamination. The project highlighted the necessity to redefine the methods to assess the quality of

Abstract - Consumers who purchase organic foods are motivated primarily by the health benefits. What assurances are there that
defining organic products based on inputs, methods, and ingredients will meet or exceed consumer expectations if there are no
re-quirements to define, measure, and meet product quality standards? The future of the organic industry will depend on
understanding and quantifying con-sumer expectations and then defining metrics for assessing organic product quality that
satisfies these expectations. After establishing quantifiable product quality targets, the next challenge will be to correlate farming
and processing methods so that the product quality criteria and consumer expectations are satis-fied.

Focusing on the issue of food safety, we consider a framework of repeated purchases under the scenario of imperfect information
on product quality (adverse selection and experience goods). A firm in a northern country can more easily detect tainted products
than can a southern one. When imports are banned, the northern firm does not always signal the actual quality of its products.
Competition from imports may lead the northern firm to test the quality of its products as a way to differentiate itself from foreign
competitors. Consumers benefit from the disclosure of information on quality, even though borders are open to products of
uncertain quality. However, competition from imports also increases the cost of signaling high quality. This can be...

In order to estimate demand elasticities of source differentiated beef in South Korea, this study used the quantity of an endogenous
demand system derived through maximizing the economic welfare of market participants including local beef consumers and local

Modelling the impact of private quality standards on the fresh fruit and vegetable supply chains in

Bruno Henry de.
Stricter quality requirements and greater uses of private quality standards have a considerable impact on the fresh fruit and
vegetable supply chain in developing countries. In particular, the future of small-scale production is in doubt. This paper presents
a theoretical game theory model to study the impact of quality requirements on producer and consumer welfare within certified
supply chains. The model shows that total producer welfare is maximized at higher quality levels where farmers who are efficient
in the production of quality products participate, whilst less efficient producers are excluded. In addition, the model provides
useful insights on welfare and poverty impact of increased competition and changes in private standard certification costs.

Carcass Quality and Genetic Selection in the Beef Industry

A lack of high-quality beef has been cited as one of the primary factors for the 50% decline in beef demand from the mid-1970s to
the last 1990s.
Cattle producers argue that appropriate price premiums are not sufficient to encourage the production of
high-quality cattle. Although some improvement in carcass quality can be made by the cattle feeding and processing sectors,
substantial improvements in quality must include genetic progress. A hedonic analysis of four major U.S. beef seedstock
producers indicates that bull purchasers place relatively high values on a bull’s ability to produce progeny with improved
carcass-quality traits.

according to the beef purchasing habits with a quality label. A logistic regression analysis was used to estimate the differences
between groups. The results show the importance of the production region as a quality aspect. Income level, association of
quality-labelled beef with “guarantee and tradition” aspects, purchasing frequency, place of purchase, production systems and
lifestyles are all variables that enabled us to establish differences between groups.

Siny.
The impact of consumer demand for quality on the agricultural and food system is an increased emphasis on quality
differentiation but not all in the direction of upgrading quality. The more elite market segments are thriving and reaching growing
numbers of consumers but the basic price/quality markets remain strong. Most recent economic studies find that consumers are
willing to pay for food safety and other quality attributes, and for information about them. The magnitude of the valuations varies
by food product, attribute, country, and study design. This literature and a case study of genetically modified foods suggest that
consumer demand has a strong effect on agricultural and food trade.

Choice and Select boxed beef. Results indicate that meat retailers have more elastic demand for lower quality graded beef.
Seasonal analysis indicates demand for both beef quality grades becomes highly price inelastic during the summer ’"cook-out"’
months. The two beef quality grades are strong substitutes during the fall and winter. However, Select beef is not a substitute for

Land Quality and International Agricultural Productivity: A Distance Function Approach

Agricultural productivity measurement has been of great interest in recent years. Although analysts have long recognized that land
quality plays an important role in agricultural productivity, land quality has been difficult to quantify and include in productivity
models due to d ata limitations. Poor land quality, in the form of desertification, erosion, and poor soil quality, as well as climate
and precipitation may limit growth in productivity over time. A Malmquist productivity index is proposed that decomposes
productivity into efficiency change, technical change and land quality components and accounts for inter-country differences in
land quality. The index is then applied to a 109-country data set covering 1980 to 2003. Many countries with lower...

efficiently applied. While there is adequate information about the costs of various inputs for reducing water quality, the costs of
achieving various outputs is much more limited. Water quality tenders show the opportunity costs of changing agricultural

The paper addresses recent changes in the Norwegian agrifood industry from the analytical perspective of quality conventions.
Storper and Salais’ “worlds of production” plus Boltanski and Thévenots’ “orders of worth” are used as a basis for the empirical
study. First, the paper discusses how the largest Norwegian branders try to strategically adapt to “novel” quality attributes like
health-enhancing food, origin/terroir, environmental sustainability and ethics. Second, the paper investigates the companies’
quality signalling strategy: How are these “novel” qualities communicated to consumers? Multiple options are available: Do they
attempt to systematically incorporate “novel qualities” into their private brand equity (“conventionalizing qualities”)? Do...

AGRICULTURAL PRICE, QUANTITY, AND WELFARE EFFECTS OF AIR QUALITY
IMPROVEMENTS
Provedor de dados: 31
Autores: Ribaudo,
Marc; Shortle,
James S.
The failure to allow for significant crop quality effects in a partial-equilibrium model can lead to misleading inferences about the
price, output and welfare implications of air quality improvements. It has been observed that air pollutants such as ozone,
sulphur dioxide, and nitrogen dioxide affect the yield and quality of many crops. The economic benefit from improving air
quality in crop producing regions has been measured using a partial-equilibrium approach which accounts only for supply shifting
yield effects. It is shown that a yield-effect only model will underestimate output increases and benefits from an air quality
improvement when commodity quality improvements as well as yield increases are forthcoming.

Quality Choice, Competition and Vertical Relationship in a Market of Protected Designation of
Origin

Autores: Bouamra-Mechemache,
Zohra; Yu,
Jianyu.
Protected Designation of Origin (PDO) is a public label that is used by the European Union as a tool to sustain the
competitiveness and the profitability of agricultural sector and in particular to maintain rural activity in less favored areas.
However, in PDO supply chain, many farmers deal with relatively few processing firms. In this framework, it is not clear that
producers under such protective policy would have incentive to adopt costly measures to improve their product qualities and
accept the restrictions on their production practices. Taking into account the vertical structure of the PDO supply chain, we
develop a model of oligopoly and oligopsony competition to investigate the conditions under which PDO producers set high
quality requirements on...

Geographical Indications and the Competitive Provision of Quality in Agricultural Markets

Autores: Moschini,
GianCarlo; Menapace,
Luisa; Pick,
Daniel H.
The economics of geographical indications (GIs) is assessed within a vertical product differentiation framework that is consistent
with the competitive structure of the agricultural sector with free entry/exit. It is assumed that certification costs are needed for
GIs to serve as (collective) credible quality certification devices, and production of high-quality product is endogenously
determined. We find that GIs can support a competitive provision of quality that partly overcomes the market failure and leads to
clear welfare gains, although they fall short of delivering the (constrained) first-best level of the high-quality good. The main
beneficiaries of the welfare gains are consumers. Producers may also accrue some benefit if the production of...

Producer's choice of certification

Autores: Langinier,
Corinne; Babcock,

Consumers are in general less informed than producers about the quality of agricultural goods. To reduce the information gap,
consumers can rely on standards (labels, certifications, geographic indications) that insure quality and origin of the goods.
However, these standards do not always fully reveal information. Some of them may just signal that the good is more likely to be
of high quality. We investigate what kind of standards are most desirable for producers, and for society in general knowing that
any system is costly to implement. One of our findings is that for intermediate values of certification costs, certification that fully
reveals information makes high quality producers better off, but make the entire industry worse off. In this case, the...

LOCATION, LAND QUALITY, AND RENTAL VOLATILITY

It appears to be widely believed that returns on low quality land are more variable than on high quality land. Using Ricardian
rent as the measure of returns and sensitivity to output price as the measure of volatility, we investigate this null hypothesis for
three different measures of quality. These are proximity to market, output productivity, and cost efficiency. In all cases, we
identify precise conditions on the production technology such that rental volatility varies in a monotone manner with land quality.
A method of econometric investigation of the relationship between rental volatility and land quality is developed and applied to
Iowa cash rents data collected during 1994-2000. Our preliminary findings provide partial empirical support for...

This paper describes the development of a learning package to support improved pasture quality on New Zealand deer farms. The
first step has been to determine the specific requirements of deer farmers that will enable them to improve pasture quality
decisions on-farm. Decision support software that interprets and demonstrates the impacts of pasture quality and animal
physiology on the performance of young growing deer has also been developed. Key themes identified to aid pasture management
decision-making included identifying the right pasture quality, management systems to maintain pasture quality and maximising
the potential of livestock. This paper reports on the type of knowledge that deer farmers require in the learning package.

Choice of variety is more important when growing organic vegetables than when growing conventional crops since severe
restrictions are placed on the treatments which organic growers can apply to maximise yield and maintain quality. In addition,
shelf life can be affected by the low nutrient levels available under organic conditions as well as the slower growth and later
maturity of organic produce. Organic produce may also have higher disease and pest loads which will affect crop value and shelf

The soil quality concept as a tool for exposing values in science and promoting sustainability
considerations

Autores: Schjønning, P.
The term soil quality has mainly been used as a technical concept for grading soils. It is important that the values and goals in soil
use planning and soil management are explicitly stated and related to the soil quality indicators. Such a cognitive soil quality
concept may facilitate the urgent need of soil scientists to interact with stakeholders in the society. Useful approaches for such
exercises have been proposed in the literature. A shift in research paradigm away from the classical, positivistic, ‘value-neutral’
approach is, however, a prerequisite for a fruitful outcome of this endeavour. The reflexive objectivity is a valuable tool in

Consumers buy organic food because they believe in the high quality of the product. Furthermore, the EU legal regulatory
framework for organic food and farming defines high quality of the products as an important goal of production. A major
challenge is the need to define food quality concepts andmethods for determination. A background is described which allows
embedding of the quality definitions as well as evaluation methods into a conceptual framework connected to the vision and

Participants in a supply chain of agricultural value-added products face significant challenges. Many of the costly distinctive traits
desired by consumers are difficult (if not impossible) to observe even after consumption. A complicating factor, addressed here, is
that in some circumstances delivered quality can only be imperfectly learned and/or affected stochastically by producers. Hence,
both symmetric and asymmetric informational imperfections may be present. In order for markets for these classes of goods to
arise, firms touting the quality of the product need to be trusted. A repeated-purchases model is developed to explore the
fundamental economic factors that lie behind the choice of different quality assurance systems and their associated...

This paper examines how ownership structure affects quality choice and the subsequent equilibrium outcomes within a duopoly

structure matters if the cost of quality at farm level is fixed or if there is a variable cost exhibiting non-constant returns to scale.
Two farm level cost functions, a fixed cost function that is increasing and convex in quality, and a variable cost function that is
increasing and convex in quantity are analyzed. The two processing firms play a two-stage game where each of the firms...

New quality assurance systems (QASs) are being put in place to facilitate the flow of information about agricultural and food

improvement. Within this paper predictors of diet quality in Canada are identified based on two cross-sectional data sets from the
Canadian Food Expenditure Survey. To measure diet quality, the Canadian Healthy Food Diversity (CanHFD)-Index is developed
which is based on Food Guide recommendations. Moreover, this paper considers that the Food Guide between survey years has
changed when analyzing diet quality. To track changes in demand for diet quality we use “Canada’s Food Guide 1982” to
calculate CanHFD-Index for 1984 and 1996. Changes in demand for diet quality according to “Canada’s Food Guide to Healthy
Eating 1992” are...

Towards a Diagnostic Instrument to Identify Improvement Opportunities for Quality Controlled
Logistics in Agrifood Supply Chain Networks

A. Luning.
Western-European consumers have become not only more demanding on product availability in retail outlets but also on other
food attributes such as quality, integrity, and safety. When (re)designing food supply-chain networks, from a logistics point of
view, one has to consider these demands next to traditional efficiency and responsiveness requirements. The concept ‘quality
controlled logistics’ (QCL) hypothesizes that if product quality in each step of the supply chain can be predicted in advance,
goods flows can be controlled in a pro-active manner and better chain designs can be established resulting in higher product
availability, constant quality, and less product losses. The paper discusses opportunities of using real-time product quality
information...

Conjoint analysis was applied to asses the part worth of beef quality and safety attributes using a cross sectional data from a
stratified sample of 300 households in Addis Ababa city collected in June 2007. Due to the absence of official standards for
quality and safety in the domestic market for beef, information on consumer perception on quality and safety attributes were
derived from a rapid appraisal. These were then used for defining product profiles in the detailed survey. Results show that,
freshness, abattoir stamp, fat content, hygiene of meat shop and staff, and price are significant quality and safety attributes that
consumers use, in the order mentioned, in their beef purchase decisions. There are differences in the relative importance of...

DEMAND FOR CREDENCE CHARACTERISTICS IN BEEF
Provedor de dados: 31
Autores: Kola,
Jukka; Latvala,

The recent food crises in Europe have raised public concerns about the quality and safety of food. The growing concern among the
consumers towards food safety issues has increased the demand for quality attributes. Most quality properties of food products can
be considered as credence characteristics, quality of which cannot be inferred before the purchase, and sometimes not even after
the purchase. The aim of this study is to evaluate, both qualitatively and quantitatively, the value of new information about and
the information systems set for credence characteristics of beef. Economics of information is the theoretical framework. The
quantitative approach focuses to measure the ex ante value of credence characteristics, and the method of contingent...

This study was carried out at Faculdade de Medicina Veterinária e Zootecnia, Universidade Estadual Paulista, Botucatu, SP,
Brazil, and evaluated bone quality in broiler breeders. Twenty-three families of Ross broiler breeders were housed in
5.0-m² pens. The families were comprised of 13 females and one male at the onset of the experimental period. The
mean number of females per family was 9.34 at the end of the trial. The feeding program and management followed strain
guidelines (Agroceres Ross, 2003). Bone analyses were performed in the right tibia and femur using optical radiographic
densitometry at 4, 8, 12, 15, 20, 24, 30, 35, 42, 47 and 52 weeks of rearing. Trap nests were used to collect eggs from the breeders

Dissolved organic carbon and bioavailability of N and P as indicators of soil quality
Provedor de dados: 63
Autores: Silveira,Maria Lucia Azevedo.
Soil quality has become an important issue in soil science. Considerable attempts have been made to define soil quality, but a
general concept has not yet been accepted by the scientific community. The selection of quantitative indices for soil quality is
extremely difficult, and a considerable number of chemical, physical, and biochemical properties have been suggested as potential
indicators of soil quality. Because soil organic matter (SOM) can be associated with different soil chemical, physical and
biological processes, it has been widely considered as one of the best soil quality indicator. Land use can significantly influence
dynamics of organic carbon and N, P, and S cycle. However, changes in total soil organic carbon (SOC) contents in response to...

This paper aims to explore consumer preference for fresh vegetables labelled as organic in combination with health and
environment related quality traits. The study decomposes organic farming into its main quality aspects and measures consumers’
preference structure for organic, in general, and for specific organic quality traits in particular. By means of stated choice
preference modelling, the following hypotheses are tested: consumers prefer health over environment related quality traits; the
organic label plays a significant role in consumers’ choice for organic products; organic farming is perceived as healthier and
more environmentally friendly than conventional farming; purchase intention is mainly driven by health related quality traits;

The UK organic wheat crop, of about 15,000 hectares, is rarely able to consistently provide flour of suitable quality to meet the
needs of the baking industry. As a result, more than 50% of the requirement for wheat in the organic bread market is imported.
This project seeks to address the constraints to the expansion of the market for organic bread produced from wheat grown in the
UK. This will be achieved by identifying the effect of agronomic practices on the protein content and quality of organic wheat.

To determine the effects of lime application on the postharvest quality of carambola fruit, an experiment with carambola trees
cultivated on an acid soil was conducted at the Bebedouro, São Paulo, Brazil. The trees were treated with increasing doses of lime
during the pre-planting period. Liming led to a increase in calcium concentration of carambola leaves and fruits. Adequate
nutrition of the plant with calcium improved post-harvest fruit quality, permitting a longer (~ 2 days) period of storage under
ambient conditions.

propose a framework for evaluating the quality of bio-ontologies. This framework is inspired by a well-known software quality
standard, which has been adapted to the needs of ontology evaluation. An example of how to use the framework, comparing two
versions of the Open Biomedical Ontologies' Cell Type Ontology, is included as an illustration.

The current cultivation practice of conventional energy plant cropping does not increase biodiversity as it was announced by
politics. Beyond that it does not minimize pesticide and mineral manure application - quite the contrary. It is a great challenge
for the organic production of energy plants to connect humus balance with the use of bio-energy. First of all the sustainable use of
liquid biogas manure must be queried regarding the nutrition quality of soil life.

Agriculture's impact on the environment is a complex research problem. A challenge to future economic research is to account
for the interrelationship between agricultural production activities, soil productivity, erosion, and water quality. It will become
increasingly important to determine not only the economic consequences, but also the environmental effectiveness of alternative

Using 23 years of data (1978-2000), this study examines seven vertically integrated sugar beet plants representing three different
companies in the United States. The objective of this research is to identify the marginal costs of producing sugar beets for
vertically integrated sugar beet processors as a way of determining the cost savings from higher quality sugar beets. In doing so,
we account for quality differences in the sugar beet input that are used to manufacture the refined sugar output. The results
quantify links between high quality sugar beets and lower processing costs.

This paper examines the effects of financial development and institutional quality on economic performance in the East Asian
economies using the panel cointegration and panel group mean fully modified OLS estimations. The empirical results based on
the Solow growth model indicate that well developed institutional quality and financial market lead to the improved output per

is embedded within a sound institutional framework. Thus, institutional improvements in these economies are important, not only
in promoting economic development but also to deliver the benefits of financial development.

An important component of the beef cow herd is the contribution of the dam to herd profitability. Yet, no research has contributed
to valuing the dam’s genetic contribution to herd quality performance or profitability. This paper examines how managing for dam
genetic pedigree quality grade affected the outcome of calf crop quality, and simulates the economic impact for different levels of

should not always be considered as a barrier to entry.

Productivity indices were calculated for rice farms across New South Wales using data envelopment analysis (DEA) techniques.
These revealed distinct geographic patterns. Preliminary work showed these geographic patterns were consistent with differences
in resource quality, including depth from watertables, soil types and salinity levels. If differences in measured productivity are
influenced by the quality of land and water resources used to produce rice, isolating this influence may provide a way of
quantifying the costs associated with resource quality issues such as rising groundwater tables and soil salinity.

Autores: Powell,

This study analyzes the local regulatory and non-regulatory determinants of ambient air quality in Allegheny, Baltimore, and
Cuyahoga Counties over the period 1972-1992. Mandated pollution control investments appear to have often had a statistically
significant effect in reducing maximum concentrations of suspended particulates and tropospheric ozone in these areas. The
effects of regulatory air quality controls, however, generally have been overshadowed by the impacts of non-regulatory factors. In
general, local regulatory and nonregulatory factors failed to account for a majority of the variation in local air quality. This
underscores the importance of regional or national factors in determining local air quality.

Aconventional assumption of product homogeneity when the commodity of interest is actually heterogeneous will lead to errors in
an analysis of the incidence of policies, such as taxes. In this article, an equilibrium displacement model is used to derive
analytical solutions for price, quantity, and quality effects of ad valorem and per unit taxes. The results show how parameters
determine the effects of tax policies on quality. The potential for tax-induced distortions in quality, and the distributive
consequences of those distortions, are illustrated in a case study of the market for Australian wine.

As agricultural products move from being economic commodities to qualitydifferentiated goods, price dispersion within specific
markets increases and implicit subsidies from high quality producers to low quality producers are removed. The present paper
examines how these distributional effects can influence patterns of support and opposition to changes in marketing arrangements.
The simple model developed is calibrated using data from the USA slaughter cattle market. Estimates of the impact on prices of
measuring quality more accurately are found to be similar in size to previous estimates of market power price suppression in the

We study whether quality assessments made by wine experts and by consumers (based on prices obtained at auction between 1980
and 1992), can be explained by variables describing endowments (land characteristics, exposures of vineyards) and technologies
(from grape varieties and picking, to bottled wines). However, since technological choices are likely to depend on endowments,
the effects can only be identified using an instrumental variables approach. We show that technological choices affect quality
much more than natural endowments, the effect of which is negligible.

The wine market is a pretty paradoxical research object for the economical and marketing studies. In France alone, every year,

process? One could think this situation to be tied to a kind of French paradox, but the number of wine brands is also increasing in
all wine producing countries whether “old”, like Spain or “new” as US. Furthermore where as most of the market theories explain
the existence of markets thanks to the happy meeting of a demand with a corresponding supply, how could we explain the growth

The choice of variety was found to be the most important agronomic instrument for the organic farmer to
secure high tuber yields and quality. Varieties Agria and Marena can be recommended as they gave high tuber yields of the
required size grade and also high French fry quality both at harvest and after storage. With regard to processing into crisps,...

The current knowledge of light quality effects on plant morphogenesis and development represents a new era of understanding on

mediated by decreasing in red far-red ratios with respect to the spectral composition of incident sunlight radiation, affecting
weed-crop interaction are the increased plant height and shoot to root ratio in anticipation of competition by light quantity, water
or nutrients. Although the concepts related to light quality have been extensively studied and several basic process of this

The quality turn in South Africa: insights from a comprehensive investigation into the food quality
behaviours, perceptions and knowledge of South African consumers with a focus on middle and upper
socioeconomic groups
Provedor de dados: 31
Autores: Vermeulen,
Hester; Bienabe,
Estelle.
Internationally, alternative food quality movements have given rise to a quality turn from the mass consumption model toward an
increasing qualitative differentiation of products and demand (Allaire, 2002). While food quality trends and their implications
have been widely analyzed internationally, little has been written on the local quality dynamics in South Africa, a country with
clear dualistic socio-economic features. This paper aims to contribute to the understanding of South African consumers’ present
food quality evaluation with a specific focus on ‘conventional’ and ‘advanced’ quality attributes associated with fresh food
produce (fruit / vegetable and meat). Primary data was collected during 2009 through an extensive nationally representative...

Batch drying of potato slices: Kinetic changes of quality parameters (colour & shrinkage) in
response of uniformly distributed drying temperature
Provedor de dados: 111
Autores: Amjad, Waseem; Hensel, Oliver; Munir, Anjum.
Uniform quality drying throughout the drying chamber of a dryer is important for a quality oriented drying process. The final
quality of dried products significantly depends upon the drying temperature. A batch type dryer was developed for uniform air
distribution. ANSYS-fluent was used to analyse the temperature distribution in the dryer. To assess the effect of drying
temperature homogeneity on quality parameters, color and shrinkage of potato slices (6 mm thick) at 60° C were measured. The
color parameters were quantified in CIELAB color space system. The shrinkage of slices (20 mm round samples) was measured
using image analysis software. The rate of color change was found uniform at all sections of drying chamber with high value of
R2. The kinetics of...

position in the global industry, ranking first in surface area, third in production and second in export volume. In recent years,
domestic consumption has experienced a clear and pronounced decline, as observed in France and Italy. Therefore, exportation
has become the main commercial avenue for table and quality wine. In Spain, designated quality wine represents 50% of total
production and has experienced commercial dynamics in international markets that differ from those affecting table wine. The

Dynamics of an estuarine ecosystem - The Chesapeake Bay experience: Statistical approaches and
water quality patterns
Provedor de dados: 5
Autores: Alden, Rw.
A long-term water quality monitoring program has been established in the Virginian waters of the Chesapeake Bay. To date, over
eight years of data have been analyzed to characterize spatio-temporal patterns and long-term trends in water quality.
Complementary multivariate statistical procedures were employed to define spatial and seasonal patterns, while a series of
non-parametric trend analyses were used for determining overall, site-specific, and season-specific long-term trends for water
quality variables in the tributaries and mainstem of the Bay. Particular attention was focused on determining the effect of river
flow on the trends, because flow rates in some of the tributaries have changed dramatically since the beginning of the monitoring
program....

Introduction : Quality attributes of fish flesh, including food safety, organoleptic features, nutritional quality and aptitude to
industrial transformation, influence consumption and acceptability of fish as food. Fish sensorial changes and texture properties
are closely linked to freshness. Along with ante mortem muscle biochemistry, postmortem biochemical processes are directly
linked to final quality attributes. The understanding of postmortem mechanisms is a prerequisite for an accurate control of the
quality of commercialized fish by the identification of objective markers or indicators. Postmortem tenderization is one of the
most important quality attributes of fish muscle. Loss of freshness is due to a complex combination of biochemical, chemical...

Cost of Living Dictates what Whales, Dolphins and Porpoises Eat: The Importance of Prey Quality on
Predator Foraging Strategies

Autores: Spitz, Jerome; Trites, Andrew W.; Becquet, Vanessa; Brind'Amour, Anik; Cherel, Yves; Galois, Robert; Ridoux,
Vincent.
Understanding the mechanisms that drive prey selection is a major challenge in foraging ecology. Most studies of foraging
strategies have focused on behavioural costs, and have generally failed to recognize that differences in the quality of prey may be
as important to predators as the costs of acquisition. Here, we tested whether there is a relationship between the quality of diets
(kJ.g(-1)) consumed by cetaceans in the North Atlantic and their metabolic costs of living as estimated by indicators of muscle
performance (mitochondrial density, n = 60, and lipid content, n = 37). We found that the cost of living of 11 cetacean species is
tightly coupled with the quality of prey they consume. This relationship between diet quality and cost of living appears...

A co-viability model of grazing and bird community management in farmland
Provedor de dados: 189
Autores: Tichit, M.; Doyen, L.; Lemel, J.Y.; Renault, O.; Durant, D.
In European grasslands, livestock grazing is a key driver of habitat quality. However, the specific grazing regimes that favour
habitat quality and ensure biodiversity conservation remain largely unknown. This paper develops a dynamic model to predict
how livestock grazing may be used to sustain a bird community without penalizing cattle feeding. The model focuses on a
grassland grazed by cattle which is also the breeding habitat of three wader species. It integrates the dynamics of a sward,
controlled through grazing, and that of three bird populations. Viability theory and dynamic programming are used to reveal
viable grazing strategies that ensure the creation of two levels of habitat quality (homogeneous and heterogeneous) whilst
ensuring cattle...

Cultural practices have been reported to affect quality and phytonutrient content of watermelon [Citrullus lanatus var. lanatus
(Thunb.) Matsum. & Nakai]. Knowing which cultivars perform well under various technologies and production systems, and
knowing how these systems affect quality and phytonutrient content is imperative to ensure high quality fruit. Organic production
and grafting are two cultural practices that are increasing among watermelon producers. Each of these technologies have the
potential to interact with cultivars to influence watermelon quality. This review discusses the effects organic culture, input level,
and grafting have on watermelon fruit quality.

Five durum wheat cultivars were grown in a Mediterranean area (Southern Italy) under conventional and organic farming with
the aim to evaluate agronomic, technological, sensory, and sanitary quality of grains and pasta. The cultivar Matt produced the
best pasta quality under conventional cropping system, while the quality parameters evaluated were unsatisfactory under organic
farming. The cultivar Saragolla showed the best yield amount and pasta quality in all the experimental conditions, thus proving
to be the cultivar more adapt to organic farming. In all the tested experimental conditions, nivalenol (NIV) and deoxynivalenol

Quality characteristics of edible linseed oil

Autores: Nykter, Minna; Kymäläinen, Hanna-Riitta; Gates, Fred; Sjöberg, Anna-Maija.
In this review the quality properties of linseed oil for food uses are discussed as well as factors affecting this quality. Linseed oil
has a favourable fatty acid composition with a high linolenic acid content. Linseed oil contains nearly 60% á-linolenic acid,
compared with 25% for plant oils generally. The content of linolenic acid and omega-3 fatty acids is reported to be high in linseed
grown in northern latitudes. The composition of fatty acids, especially unsaturated fatty acids, reported in different studies varies
considerably for linseed oil. This variation depends mainly on differences in the examined varieties and industrial processing
treatments. The fatty acid composition leads also to some problems, rancidity probably being the most...

Consumers’ use of quality characteristics to make milk purchase decisions reveal opportunities to create successful marketing
strategies. Such a strategy could concern food quality. In this case, three core areas influence consumers’ quality perception: the
perception process, the physical product itself and the communication about it (Grunert et al., 1996). Beyond this background, this
article analyzes the impact of certain quality characteristics and socio-demographics on consumption patterns regarding whole fat
milk, skim milk and organic milk. These milks were chosen because of the increasing awareness of different fat contents in the
meaning of lower fat contents being healthier and the increasing importance of the organic food market. Steenkamp’s...

In emerging markets for high-value food products in developing countries, processing companies search for efficient ways to
source raw material of consistent quality. One widely embraced approach is contract farming. But relatively little is known about
the appropriate design of contracts, especially in a small farm context. We use the example of the Vietnamese dairy sector to
analyze the effectiveness of existing contracts between a processor and smallholder farmers in terms of incentivizing the
production of high quality milk. A framed field experiment is conducted to evaluate the impact of two incentive instruments, a
price penalty for low quality and a bonus for consistent high quality milk, on farmers’ investment in quality-improving inputs....

Firms who sell a regional or specialty product often share a common or collective reputation, which is based on the group's
aggregate quality.
The dynamic problem of collective reputation is similar to the natural resource extraction problems.
Therefore, for the analysis of this particular problem, we use differential games. If there is unrestricted access to a common
property resource (the reputation stock), agents perceive its shadow value to be zero and extract too rapidly; i.e, they all "cheat" on
quality, "milking" the rents generated by the existence of the resource (reputation stock). We show that when there exists a
collective product reputation without firm traceability, the firms will extract too much from the stock of reputation. A firm is...

Participants in a supply chain of agricultural value-added products face significant challenges. Many of the costly distinctive traits
are difficult (if not impossible) to observe even after consumption. A complicating factor, addressed here, is that in some
circumstances delivered quality can only be imperfectly learned and/or affected stochastically by producers. In order for markets
for these goods to arise, firms touting the quality of the product need to be trusted. In response to these challenges, new (and
diverse) quality assurance systems (QASs) that facilitate the acquisition and flow of information about agricultural and food
products are being put in place. A repeated-purchases model is developed to explore the fundamental economic factors that...

Cereal foods' production and use show substantial heterogeneity across Europe. For a category central in most EU diets, cereal
foods' quality perception is, nevertheless, surprisingly understudied. With this in mind, 357 Danish, Lithuanian and Portuguese
citizens were inquired about the importance of several cues and dimensions in their evaluation of the perceived quality of bread,
cookies, breakfast cereals, pasta and vodka. Portuguese and Lithuanians consistently gave a significantly higher average
importance to all the cues and quality dimensions considered, for all products, than their Danish counterparts. Nevertheless,
respondents in all three samples found expected quality dimensions to be much more important than both extrinsic and intrinsic

Jason; Wu,
Steven Y.
A partial equilibrium model of stochastic crop production is used to analyze the influence of subsidized crop insurance on the
extensive margin. The addition of a crop insurance program that is characterized by a perfectly separating equilibrium and an
actuarially fair premium for each quality does not change input use or land allocation. However, Risk neutral farmers facing
actuarially fair premiums are indifferent between the purchase and not purchase decision. risk averse farmers all will purchase
actuarially fair crop insurance. Premium subsidies create incentives for the extensive margin to expand at the lower end of the
quality spectrum leading to adverse selection. Land in production without crop insurance remains in production with subsidized
crop...

Quality sorting and trade: Firm-level evidence for French wine Investigations of the effect of quality differences on heterogeneous
performance in exporting have been limited by lack of direct measures of quality. We examine exports of French wine, matching
the exporting firms to producer ratings from two wine guides. We show that high quality producers export to more markets,
charge higher prices, and sell more in each market. More attractive markets are served by exporters that, on average, make lower
rated Champagne. Market attractiveness has a weakly negative effect on prices and a strongly positive effect on quantities,
confirming the sign predictions of a simple quality sorting model. Methodologically, we make several contributions to the
literature....

The quality of reclaimed land not only relates to the way of reclamation, but also has close relations to farmers’ living standard
and households’ behaviors. Taking the farmland in the reclamation region of the Liuxin County, Tongshan Town, Xuzhou as the
survey objects, we conduct a survey on peasant households in the reclamation region by the way of questionnaire. The data
collected from the survey are analyzed
by using scientific statistical methods, including SPSS software and Excel. The results
show that in the investigation of peasant households’ perceptual knowledge towards the quality of reclaimed land, 42.5% of them
holds the satisfactory and extremely satisfactory attitudes, which take relatively high percentage. As a result of the increase of...

The physical quality of Amazonian soils is relatively unexplored, due to the unique characteristics of these soils. The index of soil
physical quality is a widely accepted measure of the structural quality of soils and has been used to specify the structural quality of
some tropical soils, as for example of the Cerrado ecoregion of Brazil. The research objective was to evaluate the physical quality
index of an Amazonian dystrophic Oxisol under different management systems. Soils under five managements were sampled in
Paragominas, State of Pará: 1) a 20-year-old second-growth forest (Forest); 2) Brachiaria sp pasture; 3) four years of no-tillage
(NT4.); 4) eight years of no-tillage (NT8); and 5) two years of conventional tillage (CT2). The soil samples were...

One way of classifying water quality is by means of indices, in which a series of parameters analyzed are joined a single value,
facilitating the interpretation of extensive lists of variables or indicators, underlying the classification of water quality. The
objective of this study was to develop a statistically based index to classify water according to the Irrigation Water Quality Index
(IWQI), to evaluate the ionic composition of water for use in irrigation and classify it by its source. For this purpose, the database
generated during the Technology Generation and Adaptation (GAT) program was used, in which, as of 1988, water samples were

Autores: Oliveira,Thalita Campos; Silva,Laura Fernanda Simões da; Cooper,Miguel.
The concept of soil quality is currently the subject of great discussion due to the interaction of soil with the environment
(soil-plant-atmosphere) and practices of human intervention. However, concepts of soil quality relate quality to agricultural
productivity, but assessment of soil quality in an agronomic context may be different from its assessment in natural areas. The aim
of this study was to assess physical quality indices, the S index, soil aeration capacity (ACt/Pt), and water storage capacity (FC/Pt)
of the soil from a permanent plot in the Caetetus Ecological Reserve (Galia, São Paulo, Brazil) under a seasonal semideciduous
forest and compare them with the reference values for soil physical quality found in the literature. Water retention...

Abstract ? The objective of this work was to construct a simple index based on the presence/absence of different groups of soil
macrofauna to determine the ecological quality of soils. The index was tested with data from 20 sites in South and Central
Tabasco, Mexico, and a positive relation between the model and the field observations was detected. The index showed that
diverse agroforestry systems had the highest soil quality index (1.00), and monocrops without trees, such as pineapple, showed the
lowest soil quality index (0.08). Further research is required to improve this model for natural systems that have very low
earthworm biomass (<10 g m-2) and a high number of earthworm species (5?7), as it is in the tropical rain forest, whose soil

An experiment was carried out from 2005 to 2008, to calibrated NIR-based instrumentation and explore within field grape quality
variability and map potential grape quality descriptors along vineyards, as a subsidy for differential harvesting,. The quality
indicators (anthocyanin content, pH, titratable acidity and soluble solids) were subject to geo-spatial modeling. Subsequently, the
data set was utilized to delineate "within-field" grape quality zone and to determine the timing of the harvest. Differential machine
harvesting was implemented and segregation of wine grapes was done "on-the-go". The approach for field prediction of grape
quality parameters and zone delineation allowed for separated fermentation for at least two wine styles.

Autores: Gebler,Luciano; Grego,Celia R.; Vieira,Abel L.; Kuse,Leonardo da R.
ABSTRACT Precision agriculture adoption in Brazilian apple orchards is still incipient. This study aimed at evaluating the spatial
variability of certain soil properties as soil density, soil penetration resistance, electrical conductivity, yield, and fruit quality in an
apple orchard through digital mapping, as well as assessing the correlation between these factors by means of geostatistics,
establishing management zones. Forty representative points were set within 2.5 hectares of apple orchard, wherein soil samples
were collected and analyzed, besides measurements of fruit quality (Brix degree, size or diameter, pulp firmness and color) to
generate an overall index quality. We concluded that the fruit quality indexes, when isolated, did not show strong...

The genetic relationships between amylose content (AC) and appearance quality traits of indica rice (Oryza sativa L.) were
investigated using conditional analysis and unconditional analysis in present experiment. The results from the unconditional
analysis indicated that AC of rice positively correlated with brown rice (BR, i.e., dehulled but unmilled rice) length (BRL), width
(BRW) and thickness (BRT), but was negatively correlated with the ratio of length to width (RLW). The conditional analysis

Provedor de dados: 189
Autores: Raynaud, E.; Sauvee, L.; Valceschini, E.
Using a Transaction Cost Economics framework, this paper studies how supply chain governance are aligned with the type of
quality enforcement mechanisms used in transactions with consumers. Specifically we compare governance of supply chains
when private brand assures quality to chains where official certification assures products' quality for customers. To test our
proposition, we conducted a set of 42 case studies in 3 agro-food sectors (processed meat, cheese, fruits and vegetable) from 7
European countries.We found that supply chain governance is closer to hierarchy-like modes of organization in cases where
reputational capital is the main quality assurance device, whereas market-like governance is more prevalent in cases with public
certification

Genotype and environment interaction on yield and quality parameters of organically grown winter
wheat – Triticum aestivum L. genotypes
Provedor de dados: 21
Autores: Dashbaljir, Ichinkhorloo; Liebhard, P.; Hartl, W.; Loeschenberger, F.; Weinhappel, M.
The interaction of genotype and environment upon yield and quality parameters of eight winter wheat (Triticum aestivum L.)
genotypes was studied under organic conditions in Austria over two growing periods, 2001/2002 and 2002/2003, respectively.
Two sites that have significantly different climatic conditions, Innviertel and Marchfeld, were chosen for the field experiment.
Study site weather and soil conditions are important yield-affecting factors. Although the yield of Marchfeld-grown genotypes
were lower, they had shown higher quality parameter values. Soil moisture conditions increase the grain yield but decrease its
quality. To obtain seed with higher quality, a production site with favourable climate conditions should be chosen.

grown using different fertilization treatments. However, in our cases with fruit of very similar standard quality, we were not able
to find complementary information to distinguish organically from conventionally grown apple fruit. Currently we are carrying

Provedor de dados: 21
Autores: Naspetti, Simona; Alberti , Francesca; Solfanelli, Francesco.
The paper presents results from an Italian study on the development of the food quality for poultry meat into the organic sector,
using the Quality Function Deployment (QFD) technique. Results show that among the visual characteristics of poultry meat
consumers assign greater importance to attributes strictly related to the animal welfare issue. Price and product appearance (colour
and fat presence) come as second. To meet these needs, producers can effectively operate along the supply chain by acting on:
housing type, genotype lines and stocking density (animal concentration/mq). Information about these issues (labelling) should
also be provided to the consumers.

Autores: Baranek, Elke; Boeckmann, Tina.
Different perspectives of consumers on products of organic agriculture were the focus of a project of the social-ecological
research program (BMBF). First results based on empirical data show that food quality - as perceived by consumers - does not
only refer to classical parameters such as freshness, ingredients or appearance. Rather, perception of food quality seems to be
closely related to how consumers feel about their quality of life. Thus, product characteristics are not only derived from their
ingredients - but also from information and personal experiences related to production processes, authenticity, and other aspects.

SOIL QUALITY AND CROP PRODUCTIVITY AS AFFECTED BY DIFFERENT SOIL
MANAGEMENT SYSTEMS IN ORGANIC AGRICULTURE "TILMAN-ORG Session"
Provedor de dados: 21
Autores: Willekens, Koen; Vandecasteele, Bart; De Vliegher, Alex.
A multi-year trial was conducted to compare soil management strategies (tillage and fertilization) with regard to their effect on
crop performance and soil quality. Two soil management systems were assessed. Farm compost application was combined with
reduced non-inversion tillage, whereas animal manure was incorporated by conventional tillage with a moldboard plough. With
regard to soil quality, a reduced tillage practice in combination with compost application seemed to be favorable for soil quality of
the surface layer in the short term. With regard to crop productivity, an effect of soil management strategy is less clear and
dependent on a seasonal variation of growth circumstances.

reviews have been unable to reach definitive conclusions after failing to ensure only valid comparisons are considered. When
methodologically flawed studies are screened out and a complete assessment of nutritional quality is made, collectively, the

Effect of organic growing systems on sensory quality and chemical composition of tomatoes
Provedor de dados: 21
Autores: Thybo, Anette K.; Edelenbos, Merete; Christensen, Lars P.; Sørensen, Jørn Nygaard; Thorup-Kristensen, Kristian.
Tomato plants were grown in open beds, confined beds, or combined beds with compost based on clover grass hay, deep litter and
peat. Due to only minor effects of growing systems on sensory quality and chemical composition of tomato fruits is was
concluded that it is possible to produce tomato fruits in confined and combined soil bed systems without any loss in eating quality.
Actually the results indicate, that a slight increase in quality of tomatoes from the confined and combined systems is obtained. The
present result points to the fact that confined and combined growing systems may be new relevant commercial growing systems,
in which the quality of tomatoes seems to be ensured, and in which nutrient loss and root diseases contamination can be reduced.

THE EFFECT OF QUALITY ASSURANCE POLICIES FOR PROCESSING TOMATOES ON THE
DEMAND FOR PESTICIDES
Provedor de dados: 31
Autores: Starbird,
S. Andrew.
In California, acceptance sampling is used to monitor the quality of processing tomatoes delivered by growers to processors. A
proposal to change the current quality assurance policy was recently put forth to reduce the growers’' incentive to use pesticides.
In this article we examine the effect of alternative quality assurance policies on profit-maximizing grower’s' demand for
pesticides. The results indicate that the demand for pesticides is sensitive to changes in the quality assurance policy and that the
proposed policy would reduce the optimal level of pesticide use on processing tomatoes. Disregarding the impacts of quality
assurance policy may be the reason that the demand for pesticides has been underestimated so often in the past.

THE DEMAND FOR FOOD QUALITY IN RUSSIA AND ITS LINKAGE TO OBESITY
Provedor de dados: 31
Autores: Staudigel,
Matthias.
This study analyses whether Russian households differ in their choice of food quality when they differ in their number of
overweight and obese members. Using survey data from the Russia Longitudinal Monitoring Survey (RLMS) for the years
1995-2005, households are classified into three weight groups. Quality elasticities of expenditures are estimated by a fixed-effects
panel model regressing unit values of several food groups on expenditures and a set of household characteristics. Coefficients for
each weight group are received by including interaction terms of expenditures and weight group dummies. A set of Wald tests is
applied to test for slope heterogeneity across weight groups. Descriptive statistics reveal that obese households actually purchase...

The main objective of this study is to account for spatial preference variability in the economic valuation of water quality
improvements in the river basin context. This is expected to be particularly relevant for the implementation of the European WFD,
as it will involve spatially differentiated perceptions of the benefits of water quality changes. A choice experiment is developed
based on maps to elicit welfare measures for water quality improvements across sub-basins in the Guadalquivir River Basin in
Spain. Variation is introduced simultaneously in the spatial distribution of goods and services and their beneficiaries, for the
accounting of spatial preference heterogeneity (i.e. people’s different valuation of changes in environmental good provision...

We examine the association between food expenditure and overall diet quality using a model where we assumed dietary quality is
a function of health conditions, life style choices, total food expenditures, and socio-economic status. We use cross-sectional

The new scene of economic globalization and commercial liberalism has instigated the increase of corporative competition. For
the cooperative or any other company to survive in the context of tough competition, one of the core issues to be concerned is
quality. In order to accompany the present changes, the vision of cooperatives has been facing important modifications. An
example of is this is Coopavel (Brazilian cooperative situated in the southern State of Paraná), which has launched a differentiated
system of raw milk payment to assure the quality of its received milk, and, consequently, the improvement of its products’ quality.
This paper proposes to present a case about Coopavel, analyzing its quality improvement program of milk production.

Studies which analyze price-quality relations in the consumer goods market are mainly more than ten years old and deal
marginally with food products. In this survey, the sceptical findings are confirmed with a special focus on the food market. The
results show that food quality, risk avoidance and increase in quality benefits are not determined by price levels. Furthermore, the
findings demonstrate that private labels in general – and the private labels of the discounter in particular – have a better
price-quality ratio than manufacturer brands and private labels of supermarkets and hypermarkets.

Matching Diverse (Quality of) Supply with Market Differentiation Opportunities in the Pork Chain
Provedor de dados: 31
Autores: Trienekens,

Currently, in most pork chains there is still a mismatch between delivered quality and expected quality, leading to unsatisfied
customers and value losses because products are not sold against the best possible price. Differentiation of quality of pork starts
already in the breeding stage, depends on feeding and living conditions of the animals at the farmer stage and is also influenced by
the way the animals are transported and slaughtered. At the breeding stage a lot of research is being done that will eventually
make it possible to use DNA technology to help guide breeding programs and to better predict the quality of animals and meat.
However, because pigs are living creatures with a natural variation, 100% prediction accuracy is not to be expected and...

The dried fruits industry in South Australia is regulated under the Dried Fruits Act 1993 (SA). The principal effect of regulation is
to impose a mandatory standards scheme on the processing and packaging of dried fruit produced in South Australia for sale in the
Australian domestic market. The Act is currently under review in accordance with the requirements and principles of National
Competition Policy. The economic analysis undertaken as part of the review addresses the question of who should be making
decisions in respect of quality standards for dried fruit: individual industry participants, industry groups or the government.

Although water quality is a valid purpose for watershed projects under the PL83-566 Watershed Protection and Flood Prevention
Act, historically very few water quality projects have ever been implemented in Arizona. This is largely due to the difficulty in
measuring "non-controversial" monetary benefits associated with positive water quality impacts and to policy biased in favor of
those projects with a higher monetary benefit-cost ratio. These reasons, among others, has prompted NRCS field economists to
seek alternate methods to measure project benefits and costs. While the direct measurement of water quality benefits would be the
preferable method to use, IMPLAN, through regional economic impact analysis, provides a way of measuring another category

The case of reduction in ad valorem tariffs as a trade liberalization policy is considered in this article. It is shown that the
reduction leads to a higher quality of imports, ceteris paribus. This hypothesis was tested on the case of Japanese beef imports
from the United States and Australia. U.S. beef, according to the results of Gallup surveys, is considered by Japanese consumers
to be a high quality product, while Australian beef is considered to be a low quality product. Empirical results support the
hypothesis. Moreover, the recent domination of U.S. beef in the Japanese market is further explained by increasingly more
efficient U.S. beef production relative to Australian production and a strong income effect, where an increase in per capita

monitoring of environmental quality. We characterize perfect public (politico-economic) equilibria in the game for the case of
both perfect and imperfect monitoring of environmental quality and compare these with imperfect private monitoring of
environmental quality. Results are discussed with respect to farmer behaviour in the context of non-point source pollution and

With credence goods consumers cannot judge actual quality neither before purchase (ex ante) nor after purchase (ex post). Trust
has to replace own examination and verification. Applying Choquet-Expected Utility theory, ageneral model of credence goods is
developed wich takes the problem of trust explicitly in its view and generalizes the problem of quality uncertainty on the 'market
for lemmons' of Akerlof (1970) to 'quality ambiguity' with credence goods. The model shows the market mechanism only
performing well in providing credence goods when consumers' trust in given information is not too low. With trust too low, sellers
of credence good will be driven out of the market by trust induced adverse selection. In market equilibrium prices will always be...

Usually, marketing communication efforts in the agrifood sector address the end consumers and concentrate on products that are

view that agricultural commodities like wheat aren’t suitable neither for product focused marketing nor branding. However, recent
developments in the in agrifood sector challenge this view. The increasing use of biotechnology, the globalisation of markets and
changing consumer demands for quality, food safety and process attributes require improved communication concepts and

The Strategic Use of Private Quality Standards in Food Supply Chains

Vanessa; Teichmann,
Isabel.
This paper highlights the strategic role retailers private quality standards play in food supply chains. Considering two symmetric
downstream firms that are exclusively supplied by a finite number of upstream firms and letting the upstream firms decide which
retailer to supply, we show that there exist two asymmetric equilibria in the downstream firms quality requirements. The
asymmetry is driven by both an increase in the retailers buyer power and the retailers competition for suppliers. The use of private
quality standards induces a decrease in social welfare, which can be softened by the implementation of a public minimum quality
standard.

We consider the consequences of a shared brand name such as geographical names used to identify high quality products, for the
incentives of otherwise autonomous firms to invest in quality. We contend that such collective brand labels improve
communication between sellers and consumers, when the scale of production is too small for individual firms to establish
reputations on a stand alone basis. This has two opposing effects on member firms’ incentives to invest in quality. On the one
hand, it increases investment incentives by increasing the visibility and transparency of individual member firms, which increases
the return from investment in quality. On the other hand, it creates an incentive to free ride on the group’s reputation, which can

outcomes. Trade-offs between quality and yield grade levels and production measures, such as average daily gain and feeding
efficiency, are evaluated. Simulation procedures are used to assess the impact of quality risk on overall profit variability. Results
make an important contribution to existing research by explaining why price signals through grid quality grade premiums may not

Roland.
It is the objective of this paper to provide a methodological framework for the analysis of regional marketing programs which
include regional-origin labeling as well as quality assurance and control. Such programs are increasingly introduced in Europe and
other parts of the world as a means against quality uncertainty in globalized markets. An equilibrium - displacement model is
developed for a segmented market with differential qualities that can be utilized for a broad variety of marketing programs. It is
applied to one selected European case, i.e. "Gepruefte Qualitaet - Bayern". It is shown that the price impacts on high-quality and
low-quality segments depend crucially on substitutive relationships between the markets and the advertising elasticities....

Does More Cooking Mean Better Eating? Estimating the relationship between time spent in food
preparation and diet quality

Autores: Mancino,
Lisa; Gregory,
Christian A.
In this study, we use a unique dataset designed by researchers at the University of Chicago and collected by Mathematica Policy
Research to investigate whether there is a significant correlation between diet quality and time spent preparing food. Overall, our
results indicate that, when controlling for unobserved factors that may affect both preparation time and diet quality, time spent in
food preparation influences diet quality only for obese persons. However, the improvements in diet quality are minimal. Our
results also indicate that foods eaten away from home play an important role in understanding the effects of time spent in food
preparation on food away from home.

Autores: Hopper,

Robert O., Jr.
Price-quality relationships for alfalfa hay were analyzed by hedonic pricing models using 1996-2001 Wisconsin auction data.
Individual nutrients included in the analysis all affected alfalfa price, with acid detergent fiber accounting for the largest impact.
Alternative pricing models, based on an aggregate quality index or detailed quality information, were similar in their ability to
predict price. However, disaggregating price predictions to account for differences in relative feed value (RFV) and crude
protein (CP) indicate that both RFV and CP are important determinants of price and that aggregating the two into a quality index
is not warranted.

Quality Management in Strategic Networks - Is there any Relevance in the Polish Dairy Sector?
Provedor de dados: 31
Autores: Hanf,
Jon Henrich; Pieniadz,
Agata.
The most striking consequence of recent food scares was that food quality is no longer the concern of a single firm, but instead the
whole food chain has to work together in order to deliver the ’new quality’. For the agri-food business there is evidence that the
majority of these more highly co-ordinated chain organisations are organised as vertical networks. The aim of the paper is to
determine the degree of influence which the chosen quality strategy exerts on the vertical co-ordination mechanism. A theoretical
framework has been developed based on new institutional economics and strategic management theory. The findings are used to
analyse the Polish dairy sector and elaborate on the relevance of quality management for this sector.

Focussing on Consumer Attention: Price-Quality Relationships and Reputation Indicators
Provedor de dados: 31
Autores: Schamel,

In Germany, the focus of agricultural policy is now "the consumer". In the aftermath of the BSE crisis, farmers are encouraged to
produce higher quality "ecological" food for which consumers are willing to pay more. Food is an experience good and quality
signals are becoming a more important determinant of the prices received. However, given consumers' cognitive limitations, all
signals can not receive equal attention. We argue that consumer attention to product quality signals increases with its producer's
quality performance, and given attention spillovers (collective reputation), with the expertise of associated producers. Over time,
collective reputations should have an effect on price when attention (or quality performance) is low, but should lose...

In the poultry industry, the use of water with adequate physical, chemical and microbiological quality it is of fundamental
importance. Since many birds have access to the same water source, quality problems will affect a great number of animals. The
drinking water plays an important role in the transmission of some bacterial, viral and protozoan diseases that are among the most
common poultry diseases. Important factors to prevent waterborne diseases in broiler production are the protection of supply
sources, water disinfection and the quality control of microbiological, chemical and physical characteristics. Water is an essential
nutrient for birds and therefore quality preservation is fundamental for good herd performance. The farmer may prevent many...

The production system using cages is a highly polemical issue in Europe, because of the space restriction imposed to laying hens.
It is considered that the cage system might compromise important comfort movements, welfare and egg quality. This study
evaluated egg quality and welfare of two strains of hens housed in a conventional system (battery laying cages) or litter system
with nest and perches, and submitted to heat stress or comfort conditions. Two groups of 20 birds (10 Hy-line W36 and 10 Hy-line
Brown) were submitted to two environmental conditions (26°C and 60% RH or 35°C and 70% RH) and two

Since 1994 important supermarket chains in Switzerland successfully sell apples from verified organic production. However, in
supermarkets customers often ask whether there are, apart from a more environmentally friendly production, objective arguments
of inner fruit quality that justify the higher prices of organic apples.
In a field study with the ‘Golden Delicious’ cultivar, we

In 1978, China initiated its economic and agricultural policy reforms. The ensuing rapid economic growth led to transportation
shortages and congestion problems and increased the demand for roads. Since 1985 the government has given high priority to road
development, particularly the construction of high-quality roads such as highways and freeways. While the construction of
high-quality roads has taken place at a remarkably rapid pace, the construction of lower-quality and mostly rural roads has been
slow. This study evaluates the contribution of roads to economic growth and poverty reduction in China. It disaggregates road
infrastructure into different classes of roads to account for quality, and then estimates the impact of road investments on overall...

market retailed prices revealed quality preferences of the consumers and not only production costs. In very poor countries like
Mali, food innovation is limited by the very low purchasing power of the population. However, technological food product or

further. The overall objective was to investigate different strategies for production of organic eggs of high and differentiable
quality regarding appearance (yolk colour and carotenoid composition), sensory quality, shell strength and egg albumen protein
content providing more diversified eggs compared with conventional eggs. Specific objectives were to study the effect of hen
genotype (layer-type versus “dual purpose”- type), identify new protein feed sources for organic laying hens in order to improve

Roots and Compost, - organic crop production under reduced nutrient availability
Provedor de dados: 21
With plans to phase out manure import from conventional farms, it will become increasingly difficult to secure plant nutrients for
organic crops. In the RoCo project we will address this problem through three approaches: 1) study variation in root growth and
root hair formation among cultivars of wheat, onion and lettuce, to identify superior cultivars and critical root traits which can be
used as breeding objectives for new cultivars for organic farming, 2) study recirculation of urban nutrient sources through
composting, to make them good fertilizers and study what make them acceptable for consumers and organic farmers, and 3) with
wheat baking quality as example, study whether we can solve some of the quality problems caused by nutrient limitation by...

Fluorescence-based concept of Naturalness applied to organic processed fruit and vegetables
Provedor de dados: 21
Autores: Bardeau, F.; Rizkallah, J.; Acharid, A.; Sivault, S.; Neugnot, B.; Kahl, J.; Birlouez, E.; Birlouez, I.
Background: According to the European regulation N°834/2007, processing of organic food should preserve the essential qualities
of the fresh raw material. Thus, assessment of processed food quality should include verification of the absence of additives and
contaminants and preservation of the sensorial, nutritional and health values of the raw material. In this paper, a quantifiable
concept of naturalness measuring global quality loss due to processing and storage of raw organic material is proposed. This
indicator is based on Front face fluorescence; a global and sensitive technique able to assess in real time and non-destructively
these various dimensions of the food quality.
Results: A strong relationship between the naturalness levels estimated...

Superb and Marketable Meat from Efficient and Robust Animals
Provedor de dados: 21
With the aim to increase the production and market share of organic meat (pork, poultry and young beef), an integrated research
and de-velopment effort will take place along the food chain (primary production, product development and market-ing). The
hypothesis is that this product segment is presently underdeveloped due to incompatibility between production costs/consumer
prices and the experienced quality of the products, and that this incompatibility primarily should be overcome by adding quality in
a broad sense to the organic meat products. Among the immaterial qualities are that the animals are healthy as well as robust, are
free-ranged, and is more integrated in the land use (relying to a large extent on on-farm resources) than actually present. In...

Organic farming (OF) is increasingly considered as a possible alternative for designing a "new rural" in Brazil, where OF covers a

Concept for quality management to secure benefits of compost use for soil and plants
Provedor de dados: 21
Autores: Fuchs, J.G.; Berner, A.; Mayer, J.; Schleiss, K.
Use of quality compost can have an important positive impact on soil fertility and plant growth and health. For example, it
increases soil humus and improves soil structure and suppressivity towards plant diseases. To obtain these positive results, it is
important that the compost quality is appropriate for each use. If used inadequately, the impact of compost can also be negative.
The compost producer should be responsible for the quality of his products, and has to communicate the properties of his
composts to the users. But to be successful, the compost users have to communicate to the producers the manner in which the
compost is to be used. To support compost producers and users in this process, the Swiss producers of compost and digestate

In the European Union member states (EU), it is necessary to evaluate hygienic condition of milk in order to determine milk price.
Similar requirement was set by the Republic of Croatia in 2000. The Rulebook defines minimal quality criteria that fresh raw milk
must have in order to be purchased. Upon completion of analysis, milk is classified into quality classes, each having a defined
price. Increased value of somatic cell count (SCC) (higher than 400.000/ml) and MO (higher than 100.000/ml) directly decreases
the raw milk price, while higher content of fat and protein causes its increase. Since the system of market milk price formation
was established, producers have been stimulated to produce milk of higher quality: in a total of milk being purchased,...

When products are differentiated and quality is highly subjective (e.g., fashion or art), novel (e.g., a new feature), or difficult to
verify prior to purchase (e.g., credence attributes), consumers may turn to price as a signal of quality. Products containing
genetically modified (GM) ingredients meet each of these criteria, i.e., GM ingredients are novel, their presence is difficult to
verify, and their impact on subjective quality may be viewed differently across individuals with the same knowledge. We add to
the limited empirical literature on consumers' use of price as a quality signal by testing for non-monotonicity of consumer demand
in price for GM products using data collected from a nationally representative mail survey featuring several...

allow trees to express their genetic potential, and time and rate of application should be scheduled to promote fruit quality.
Grapevine berries, must and wine quality are affected principally by N, that regulate the synthesis of some important compounds,
such as anthocyanins, which are responsible for coloring of the must and the wine. Fermenation of the must may stop in grapes
with low concentration of N because N is requested in high amount by yeasts. An N excess may increase the pulp to peel ratio,...

The occurrence of green seeded soybeans [Glycine max (L.) Merrill] is a problem closely related to unfavorable climatic
conditions, mainly drought, that occurs during the final stages of seed maturation. This problem causes serious losses to soybean
seed quality in Brazil. In these seeds, chlorophyll is not properly degraded during maturation, drastically reducing seed quality.
Using the chlorophyll fluorescence technique, it is possible to remove green seeds from the seed lot, improving seed quality in
several species in which the occurrence of green seeds is also a problem. The objective of this research was to study the use of the

Autores: Zander,T.; Yunes,J.A.; Cardoso,A.A.; Nadler,L.M.
The interpretation of oligonucleotide array experiments depends on the quality of the target cRNA used. cRNA target quality is
assessed by quantitative analysis of the representation of 5' and 3' sequences of control genes using commercially available Test
arrays. The Test array provides an economically priced means of determining the quality of labeled target prior to analysis on
whole genome expression arrays. This manuscript validates the use of a duplex RT-PCR assay as a faster (6 h) and less expensive
(<US$10) but equally accurate alternative to the Test arrays in determining biotinylated cRNA quality. Forty-one different
cRNA samples were hybridized to HG-U133A microarrays from Affymetrix. Ten cRNA samples with a ß-actin 3'/5' ratio >6

Popular concern over water quality has important implications for public water management because it can both empower water
utilities to improve service but also limit their ability to make changes. In the desert city of Phoenix, Arizona, obtaining sufficient
high-quality water resources for a growing urban population poses a major challenge. Decision makers and urban hydrologists are
aware of these challenges to water sustainability but the range of acceptable policy and management options available to them is
constrained by public opinion. Therefore, this study examines cultural models of water quality and water management, termed
ethnohydrology, among urban residents. The study yields three key findings. First, urban residents appear to have a shared...

Quality soil management or soil quality management: Performance versus semantics
Provedor de dados: 18
Autores: Sojka, R.E.; Upchurch, D.R.; Borlaug, N.E.
In the past 200 years, soil science has used reductionist research to develop agricultural technologies that have unlocked the
hidden potential of earth's natural systems to feed, clothe, and provide raw materials to the human population of over six billion.
The soil quality paradigm seeks to change that scientific approach, the nomenclature of soil science, and institutional priorities for
soil management and research. The definition of soil quality is elusive and value-laden. Concerns exist for the paradigm's policy
overtones, regional and taxonomic biases, failure to reconcile conceptual contradictions, as well as its ambiguous definitions that
are confounded by countless circumstance-specific, function-dependent scenarios. The paradigm does not...

The aim of this review is to provide an update on factors contributing to quality of carrots, with special focus on the role of preand postharvest factors and processing. The genetic factor shows the highest impact on quality variables in carrots, causing a
7–11-fold difference between varieties in content of terpenes, β-carotene, magnesium, iron and phenolics as well as a 1–4-fold
difference in falcarindiol, bitter taste and sweet taste. Climate-related factors may cause a difference of up to 20-fold for terpenes,
82% for total sugars and 30–40% for β-carotene, sweet taste and bitter taste. Organic farming in comparison with conventional
farming has shown 70% higher levels for magnesium and 10% for iron. Low nitrogen fertilisation level may cause up to...

Despite special quality of the olive oil of Trás-os-Montes (TM), producers fail to create niche market and raise price
commensurate with the high cost. Some local manufacturers made some attempts to establish special brands for their oil and the
association of the local producers (AOTAD) made the required efforts to bring the product of the region under PDO, designated as
Azeite de Trás-os-Montes DOP. Only a small part of the marketed product is sold under PDO (4%) and a fraction of which is sold
under some brand till date. The cost structure of olive oil depends on multiple factors - the type of production system (traditional
or intensive), plant variety, inclination of plots and productivity, among others. The harvesting cost in general represents more...

Achieving consistency in hog quality has been one of the greatest challenges in the US pork industry. Packers, processors and
retailers all ranked lack of uniformity in live hogs, carcasses, and retail cuts with regard to size and backfat as the most important
quality issue facing the industry in the mid 1990s (NPPC, Pork Quality Audit, 1994), and quality consistency continues to be a
leading industry concern (Martinez and Zering, 2004).
The past 15 years have also witnessed dramatic changes in the
organization of the US hog industry. In 1993, over 82% of hogs were sold through spot markets while 11% were sold under

The appearance of consumers groups increasingly concerned about the quality of food products, together with an increasingly
competitive environment and domestic saturated markets, has led companies to achieving differentiated quality. The wine sector is
immersed in this situation. Valuation of this differentiation by consumers will not happen by complying with certain standards or
technical specifications, but rather it has to be perceived by consumers. Unlike experts, consumers cannot easily know which
properties are intrinsic to products, which are those that give them their quality. There is, thus, a problem of uncertainty regarding
the quality of products. This problem becomes more complex when consumers are faced with many alternatives of a similar...

The aim of this study was to find alternatives to reduce the cost of mass production of the South American fruit fly (A. fraterculus)
by looking for locally available products as protein source in the diet of adults to replace the imported product without changing
the quality parameters. Two yeast from a Brazilian company were evaluated. The quality parameters showed that the imported
hydrolyzed yeast used in the adult diet could be perfectly replaced by the local products tested, with a reduction of over 80% of
the cost of the diet. The quality of the produced insects remained the same and there were improvements in some quality
parameters such as the volume of eggs produced, number of adults flying and longevity under the stress.

Bread-making quality is one of the most important targets in the genetic improvement of wheat. Although extensive analyses of
quality traits such as farinography, sodium dodecyl sulfate (SDS) sedimentation, alveography, and baking are made in breeding
programs, these analyses require high amounts of seeds which are obtained only in late generations. In this experiment the
statistical correlations between the high molecular weight subunit of glutenin and bread-making quality measured by alveograph,
farinograph and SDS sedimentation were evaluated. Seventeen wheat genotypes were grown under the same conditions, each

The objective of this study was to evaluate the alterations in sleep and circadian parameters during the aging process. The study
sample comprises volunteers older than 18 up to 90 years of age that answered the Pittsburgh Sleep Quality Index (PSQI) and the
Horne and Östberg circadian preference questionnaire. We observed that the shift to morningness with increasing age is associated
with a significant worsening in sleep quality. We discuss that this sleep profile characterized by morningness and worse sleep
quality observed in elderly, when compared to younger people, reflects not necessarily a pathological state, but an expected
profile for this age group.

Effect of wheat flour protein variations on sensory attributes, texture and staling of Taftoon bread
Provedor de dados: 116
Autores: Salehifar,Mania; Ardebili,Mehdi Seyedein; Azizi,Mohammad Hosein.
The quality of flat breads depends in part on the textural properties of breads during storage. These properties are largely affected
by flour protein quality and quantity. The present study aimed to examine differences between sensory properties, textural and
staling of Tandoori breads made from flours of different quality and different quantities of protein. This was implemented by
using three flours with 9.4, 11.5 and 13.5% protein contents and different protein qualities shown by Zeleney sedimentation
volume 16.25, 22.75 and 23.25 mL respectively. Bread strips were submitted to uniaxial compression between two parallel plates
on an Instron Universal Testing machine, and firmness of the breads was determined. Results indicated the differences in the...

Effect of different proportions of brea gum in the functional characteristics of wheat flour starch:
impact on the physical quality of bread
Provedor de dados: 116
Autores: LÓPEZ,Estela Patricia; JIMÉNEZ,Patricia Liliana.
The aim of this work was to study the changes induced by BG in the behaviour of wheat starch, and observe the influence of these
variations on the quality of a basic white bread. The effect of four BG addition levels in the wheat flour functional characteristics
(WAI, WSI, and pasting properties) and bread quality (physical parameters, crumb grain structure, moisture and hardness) was
investigated. The highest levels of BG (1% and 2%) decreased the peak viscosity, and increased the stability and setback of the
flour. This was due to a lower gelatinization of the starch granules, caused by a competition for water between the hydrocolloid
and starch. These changes influenced the bread quality. The loaves added with 1% and 2% of BG presented smaller alveoli:...

ABSTRACT: Land use outside its agricultural potential and low vegetation cover in the watershed impair the quality of water
used for irrigation and may contribute to the spread of pathogenic coliform bacteria. The objective of this study was to relate the
quality of irrigation water with the intensity and type of land use and the rainfall in a vegetable-producing region of São José dos
Pinhais, Paraná. Water samples were collected monthly in 2013 from two reservoirs and one preserved source. After collection,
the samples were chilled in Styrofoam boxes and transported to the laboratory for analyses of the total and thermotolerant
coliforms. Effect of land use was analyzed by probability estimation trees. High land use and weekly above average rainfall...

Autores: Lima,Márcio S. de; Cardoso,Antonio I. I.; Verdial,Marcelo F.
Squash seeds yield and quality can be improved by proper population plant spacing and the pollen quantity, which influences the
pollination quality and fertilization. Nine experiments were conducted as a factorial combination of three spacing between plants
(0.8 x 0.3, 0.8 x 0.6 and 0.8 x 0.9 m), two quantities of pollen (50% of an anther and another entire one) and natural insect
pollination. Seed and fruit production parameters, and seed quality were evaluated. A randomized complete block design, five
replications, with ten plants per plot was adopted. Larger plant spacing increased the average number of mature fruits and seed
yield per plant. Seed yield was directly proportional to the amount of pollen used during pollination. Higher amounts of pollen...

Definition and Application of a Quality Estimator for Multibeam Echosounders
Provedor de dados: 5
Autores: Ladroit, Yoann; Lurton, Xavier; Sintes, Christophe; Augustin, Jean-marie; Garello, Rene.
For modern multibeam echosounders, the use of a robust and reliable quality estimator associated with each sounding is an
absolute necessity. Indeed, due to the large volume of data acquired, a lot of time is lost, both during the survey and the
post-processing. This is a costly problem for hydrographers. The definition of a quality estimator based on the characteristics of
the beamformed signal gives an answer to this problem. It has been successfully implemented by several sonar manufacturers and
its relevance in measuring the quality of each sounding has been demonstrated. The defined Quality Factor can also be used
directly in the sonar measurement process, such as in detection algorithm, in order to improve the performance of the systems.

In order to improve Our understanding of factors determining egg quality in fish, seabass egg batches obtained from 34 females
held under standard conditions, were assessed for biological performances and a fraction from each batch was subjected to
proteomic analysis. Comparison of proteomic patterns from eggs of different quality revealed differential protein spots among
which one was identified as Nucleoside Diphosphate Kinase, a highly conserved protein involved in cell proliferation. This study
shows that molecular markers may help understand factors determining egg quality in fish.

Echinoderm egg and larval quality as a function of adult nutritional state
Provedor de dados: 5
Autores: George, Sb.
Differences in egg and larval quality for some sea urchins and seastars were investigated in the field acid in the laboratory. In the
field, sea urchins and seastars found at sites with an abundant supply of food were larger, and they produced large numbers of
large, high quality eggs. For some female seastars, nutritional history determined the response to variation in food supply in the
laboratory. While an increase in food ration did not affect the size of eggs produced by females from the favorable site, an
increase in food ration led to an increase in egg size for those from the less favorable site. For all the echinoderms examined, egg
numbers decreased when conditions became unfavorable. Larvae from females living in favorable environments grew and...

France is one of the world top producers of oysters and mussels by aquaculture with 140 000 tonnes of oysters, 60 000 tonnes of
mussels and an ex-farm turnover accounting to 350 millions US$ in 1996. The French market is by far the largest one in Europe
for oyster and is supplied entirely by domestic production, with very little external trade. On the contrary, the French market for
mussel is a very competitive one, widely open to imports. Given the evolution of market conditions due to the development of
supermarkets, to the competition of new value added products and to the modification of consumer's habits, the French oyster and

Technologies to minimize water quality impacts of irrigated agriculture

Irrigation transformed arid land in the Pacific Northwest into productive agricultural land. However, much of this land is prone
to erosion during irrigation, which can cause problems on and off of the field. Management practices have been developed to
control soil erosion on irrigated land and improve the quality of water returning to streams and rivers. Applying polyacrylamide
(PAM) with irrigation water can reduce erosion from furrow irrigated fields more than 90%. Using PAM in combination with
other practices, such as applying straw mulch in furrows and installing small sediment ponds on fields, can virtually eliminate
sediment loss from fields. Once soil runs off a field, it can be removed by settling in sediment ponds, although soluble...

Effect of weed management strategies on the risk of enteric pathogen transfer into the food chain and
lettuce quality
Provedor de dados: 21
Autores: Fischer-Arndt, M.T.; Köpke, U.
The hygienic quality of raw edible vegetables such as lettuce may be influenced by
pathogen transfer from soil to plant, which
might occur during weed control by hoeing or as splash-effects during rainfall. The hygienic quality is often discussed when
farmyard manures are applied during production, as e.g. in organic farming systems. In a field experiment, the effects of weed
control on pathogen transfer from soil fertilised with farmyard manure to lettuce (Lactuca sativa, var. capitata) were evaluated.
First results do not confirm pathogen transfer by mechanical weeding or splash effects during rainfall.

Field pea (Pisum sativum L.) and wheat (Triticum sativum L.) were either sole cropped or intercropped in a complete design of
five relative proportions and five density levels to determine the effects of interspecific interaction in an intercrop on wheat baking
quality. It is shown how pea interspecific competitive ability for factors such as light and water results in an increase in wheat
protein content without reducing other important quality parameters. Density and relative crop frequency can be used as

Abstract - In organic farming winter wheat is typically grown after good pre-crops, as it pays well for this in terms of yield and
quality. However, winter wheat develops slowly during the autumn, and much nitrate may be lost by leaching before spring.
System with catch crops followed by spring wheat, or maybe catch crops intercropped with winter wheat could improve the
utilization of the pre-crop effects in wheat crop-ping. In this experiment we studied wheat and catch crop root growth, crop and
soil N dynamics, and ef-fects on yield and baking quality in wheat cropping systems with catch crops. The results showed that
the combination of catch crops and spring wheat increased the yield and decreased the gluten content, but the bread volume was...

Autores: Fuchs, Jacques G.; Mayer, Jochen; Berner, Alfred.
One hundred Swiss composts and digestates were investigated in order to evaluate their influence on plant growth and health.
Important differences in biological compost quality and on the impact on soil fertility and on plant health were observed. The
most important limiting factor of compost quality is the possible immobilization of mineralized nitrogen by some composts.
However, quality composts have a good potential to protect plants against diseases. More attention should be paid to the control
of the composting process in order to improve the biological quality of composts with more beneficial effects on crops.

Eating quality of Holstein bull calves fed only grass or purely herbs matches that of concentrate-fed
veal calves
Provedor de dados: 21
Autores: Therkildsen, M.; Jensen, S.K.; Vestergaard, M.
Organic meat production from Holstein calves born in dairy herds require that the bull calves are raised outdoor at least 6 months
a year, and on large quantities of roughage in the diet. This study aimed at elucidating if Holstein bull calves fed either purely
grass or purely herbs prior to slaughter would differ in meat quality traits, fatty acid composition and sensory profile and if they
differed in quality aspects from concentrate-fed veal calves.

Disease control with quality compost in pot and field trials
Provedor de dados: 21
Autores: Fuchs, Jacques; Larbi, Mohamed.
Quality compost can have a positive effect on soil fertility and plant growth and health.
This positive effect is not only
observable in the laboratory, but also by growers. Phytopathological problems could be solved with the use of compost.
Durable success can only be obtained if a quality management is resolutely followed. Further research is needed to optimize the
quality management of compost production and utilization. For example, very little is known about the long-term effect of the
different composts on soil fertility and disease receptivity.

Organic vine growing: from breaking new ground to bringing back the taste of the terroir

Organic farming certification has certainly contributed to unifying organic production, particularly by reducing the number of
private charters. However, this reduction should not be misleading. Organic agriculture cannot be reduced to just a label and
includes other requirements related to ethics, agronomy and economic policy whose implementation contributes to the
diversification of marketing organisations that selectively ensure the marketing of organic products. Furthermore, in the case of
viticulture, organic producers have recently placed more emphasis on the taste quality of their wines that they have linked in
various ways to the quality of the environment. This new link between taste and environment has added a new complexity to

Autores: Mazzoncini, Marco; Belloni, Paola; Risaliti, Rosalba; Antichi, Daniele.
In the frame of a long-term experiment carried out in Central Italy, conventional and organic winter wheat cropping systems were
compared in 2004 and 2005 to evaluate the effect of system management on wheat grain yield and quality. The organic system
showed grain and straw yield about 50% lower than the conventional system. Organic grain samples resulted 20% lower in protein
content and exhibited poor bread production qualities. Despite that, organic bread, did not show differences in crust thickness,
crumb volume and in crumb alveolus structure in a visual evaluation. Differences were, however, appreciated by panellists who
found organic bread harder and more flavourful than conventional.

In order to investigate if there are differences between endangered or modern pig breeds concerning growth and product quality a
total of ninety fattened pigs were housed and fed after the principles of the organic farming. During the fattening period the
animals got regularly weight and measured alive with magnetic resonance tomo-graphy (MRT) in order to research tissue growth.
After achieving a live weight of about 120 kilogram the pigs got slaughtered. After slaughtering the carcass quality was acquired,
samples were taken for investigating the meat quality and one carcass side was measured again with the MRT. Results point out
that differences exist between the breeds concerning the attributes of growth, carcass and meat quality.

Specific conditions of organic farming are often limited nitrogen supply and – depending on the year - early occurrence of P.
infestans. In addition, genetic (variety) and environmental (site, year) factors may have strong effects on both the yield and quality
of tubers with regard to their suitability for processing. This study examined the impact of variety and site on the yield structure
and quality of tubers for processing to chips at three sites over two years. According to the results, the varieties Agria and Marena
with high yield and good quality after harvesting and storage were interesting for organic farmers.

The efficacy of the processed kaolin “Surround WP” to control olive fruit fly, Bactrocera oleae Gmelin, field infestations was
investigated in east Calabria. The preliminary results showed that fruit infestation levels were significantly reduced on
kaolin-treated trees compared with untreated trees. The promising results of these experiments points to the feasibility of using
particle film technology composed of a non-toxic material, to avoid olive fly damage as an alternative to the applications of
rotenone in organic orchards. Finally, kaolin treatment unaffected the nutritional and sensory quality parameters of the
corresponding virgin olive oils obtained by a laboratory scale olive mill, thus satisfying the present quality requirements.

Yield and quality (bulb size, sugar content and composition, pungency, initial sprout growth) of early and late transplanted and
directly sown onions (cv. Sturon) were compared in field experiments (2009-2011) at different intensities of weeding (weed-free
or mechanical weed control only). Early transplanting (weed-free) resulted in the highest yield and best quality performance,
whereas late transplanting combined with mechanical weed control only (including harrowing weeds before transplanting
onions) resulted in medium yield and quality, however, at a relatively low work-input. It is suggested that infection by powdery
mildew was the key limiting factor in the development of yield and quality in late-transplanted and directly-sown onions.

This study estimates wholesale demand for pork, chicken, and quality differentiated beef. We estimate meat retailer own- and
cross-price demand elasticities for USDA Choice and Select boxed beef. Results indicate that meat retailers have more elastic
demand for lower quality graded beef. Retail beef price has a strong positive relationship with Choice and Select boxed beef
demand, and a strong negative relationship with wholesale pork and chicken demand. Seasonal analysis reveals demand for both
beef quality grades becomes highly price inelastic during the summer months. The two beef quality grades are substitutes during

This study seeks to explain the differences in infrastructure quality across China’s villages. Using primary data on three main
types of infrastructure projects in rural China, we find that a.) between-project within-village quality differences are small and
project design has little explanatory power; b.) between-village variations are larger; and c.) there are strong correlations between
the ways villages govern themselves and project quality. We conclude that it is difficult to make good projects work in bad

The globalisation of processing industry and the consolidation of the international retail trade, together with the increase of
imports after the EU access, supported the competition hot up and saturation of domestic food market. Both food processors and
food retailers are exposed to increasing competition. In order to maintenance on the market they are increasingly pressed to
minimize their costs and/or to accomplish higher prices for products with competitive advantage. Besides of that all participants of
the agri-food chain are pressed to intensify marketing support of their goods. Aiming to reduce the costs, some of processors
choose the way by the substitution of part of the input material by another, cheaper one. On the other hand, the offer of...

The quality of many goods and services may change randomly between the time of shipment and delivery, creating disputes over
quality that can result in lemons-market equilibria. We investigate the potential of third-party inspections for such inefficiencies.
We consider two types of inspection, ex post verification of quality in consignment contracts and ex ante certification in FOB
contracts, which were instituted for fruits and vegetables in the U.S. when national markets were emerging. We show that both
types of inspection can counteract misallocations of quality found in lemons-market equilibria. Buyers prefer ex post verification
to ex ante certification while sellers prefer the reverse. Government provision of inspection services may be...

This paper analyses the effect of environmental and quality improvement practices on the value added of the fruit and vegetable

investment in quality-environmental activities as knowledge capital, we propose a specific analysis that evaluates the effect of the
factors of the production function and of the current subsidies over the value added. In general, the share of quality environmental
activities in the rise of the product's market value is quite high. The analysis reflects that the expenditure on these activities is still
higher than their benefit, and that the current subsidies can hardly be considered encouraging factors for...

This paper examines quality-price relationship in U.S. soybean exports. Implicit prices for quality characteristics of U.S. soybean
exports were estimated using a hedonic price function from a rich transaction-specific data set to major destination markets to test
the efficiency of the market in transmitting preferences for quality. The results of this analysis suggest that the price of soybean
export shipments was not affected by the oil and protein content of the soybeans. Moisture content was surprisingly found to
positively affect price while foreign material reduced price after the 1989-1990 marketing year. These results are discussed for
their implications for existing, and proposed changes to existing, soybean market regulation.

Consumers show an increased interest in organic food today and a willingness to pay premium for organic products. In addition to
price, changing attitudes and beliefs about food quality affect food choice. This article analyses the impact of attitudes, quality
characteristics and socio-demographics on consumption of organic and conventional pork, potatoes and milk. The concept of
’perceived quality’ provides the theoretical background. The data come from a consumer survey conducted in Germany in 2004
(n=260). An ordered logit model was used for analysing the data. We observe clear differences in consumers’ use of certain
quality characteristics as they perceive and evaluate conventional and organic fresh foods.

We hypothesize that quality signals improve over time with the quality performance of a wine producer, and that spillovers will

wine. Data source is the annual publication "California Wine Winners" accumulated over the judging years 1990-2001. Quality
indicators for 19,583 wines are medals awarded during nine annual wine competitions, variety, regional origin, judging age as
well as derived producer (brand) and regional reputation indicators. The data confirms that a wine's price is related to its own
quality and to producer/regional reputation for quality.

Many public programs promote diets rich in fruits and vegetables based on evidence of the derived health benefits. Still, produce
consumption in the United States lags behind other nations, even its most culturally similar neighbor--Canada. This study uses a
structural latent variable model to test the role played by quality and health information in explaining observed differences in
produce consumption. The Alchian-Allen effect predicts that higher quality, higher absolute margin produce will be exported,
suggesting quality may be an important demand factor in importing nations such as Canada. The results show that dietary health
information is significant in expanding demands. Quality also promotes fruit consumption in Canada.

We analyse the competition in quality and quantity between a foreign firm and a domestic firm. The domestic firm can belong to a
certification of origin, whereas its rival uses a pure brand strategy. We will show how the certification can allow the domestic firm
to position itself as a high quality producer and improve the average quality of the products offered on the market. If, however, the
certified firm offers the low quality good, the certification can permit it to guarantee a higher profit than that of its competitor and
to improve the consumers' surplus by favouring product standardisation.

Quality Signaling through Certification

This paper analyzes the problem raised by quality provision in globalizing economies. When quality is a credence attribute, there
is a signaling problem and quality drops to its minimum level. A way out of this under-provision equilibrium consists to rely on
certification. However certification of goods involves costs, most of which are fixed, because to credibly signal quality, the
certification process has to be carry out by an independent authority above all suspicion. The certification costs, which might
justify a centralized intervention, become a major force in deciding market structure. Then in a given population the rate of
certification depends on the consumers' wealth and size. If the population is too poor the market for certification collapses...

This paper provides an original theoretical framework to better understand the raise of private quality standards in agrifood chains.
Reasons for the development and conditions for the effectiveness of private quality standards are identified, by investigating
firms’ strategic behaviour and, more precisely, both interactions among processing/retailing firms and upstream producers and the
role of consumers’ behaviour. Considering different levels of consumers risk perception, we show that the incentive for firms to
develop a more stringent private standard may increase with the level of the regulated minimum quality standard. Moreover,
setting a private standard may reduce the risk of consumer dissatisfaction while increasing the marketed quantity....

Timely adoption of new varieties is critical to profitable peach production, and peach quality is a primary factor driving adoption.
An adoption model for peach varieties is estimated, incorporating grower evaluations of peach quality. The model identifies the
impact of farm characteristics such as the farmer's quality preferences, on-farm agronomic and orchard conditions, as well as
geographic effects in Georgia peach-growing regions. The relative impact of the key external and internal peach quality attributes
on adoption is assessed. Decisions on new varieties are influenced by the age distribution of the orchard, information which can be
used in targeting new varieties to growers.

Econometric models were developed to estimate the implicit prices for selected quality attributes of fresh peaches commercialized
in the state of Sao Paulo. Such estimation is conducted in two stages of the distribution chain, namely, wholesale and retail sales.
Data on the price and quality attributes (such as color, size, varieties and types of damages) of fresh peaches were obtained from
cross-sectional data in different time periods. The estimation of Hedonic Prices is proposed as a method to evaluate post-harvest
price variations from wholesale to retail sales. The results obtained allowed us to identify the gains accrued in each stage, deriving
from the improvement in the product quality attributes.

This paper uses the principal-agent theory to analytically investigate the optimal incentive-based compensation contract that a

literature on multi-task principal-agent models by analyzing the quality-quantity trade-off and studying the implications of such a
relationship in the principal-agent framework. One striking result of these effects is that, under appropriate incentive-based
grower’s compensation, the processor may encourage grower’s effort in quality without crowding out grower’s effort in quantity.

Four alternative payment rules were examined to evaluate their ability to accomplish the objectives of the development rights

Competitive bidding (as auctions) is commonly used to procure goods and services. Public buyers are often mandated by law to
adopt competitive procedures to ensure transparency and promote full competition. Recent theoretical literature, however,
suggests that open competition can perform poorly in allocating complex projects. In exploring the determinants of suppliers’
bidding behavior in procurement auctions for complex IT services, we find results that are consistent with theory. We find that
price and quality do not exhibit the classical tradeoff one would expect: quite surprisingly, high quality is associated to low prices.
Furthermore, while quality is mainly driven by suppliers’ experience, price is affected more by the scoring rule and by the level...

By endogenizing unit value and coupon redemption, we estimate U.S. household cheese purchase, quality choice, and coupon
redemption equations simultaneously. Zero purchases and missing values are taken into account in the model to correct for the
selectivity bias. The correlations among the three equations are found to be significant. Empirical findings show that high quality
choice significantly decreases cheese purchases, while cheese coupon usage significantly increases purchases. We find that higher
income households select higher quality cheese, while larger households choose lower quality cheese. Frequent coupon redeemers
are found to purchase lower quality cheese. For coupon redemption, we find that African American households redeem less

The most widely used measure of milk hygiene is Somatic Cell Count (SCC), where low SCC values indicate more wholesome
milk. Dirt, often associated with grazing, carry bacteria and these bacteria can cause mastitis. Milk from cows with mastitis
generally has higher SCC levels and cows with mastitis are most readily treated with antibiotics. Milk with high SCC is penalized
by distributers as it is difficult to process and is not considered as wholesome in fluid markets. Grazing cows is common for many
organic farmers. However, regulators prohibit antibiotic use under organic production. Intensive management protocols,
maintaining equipment, and closely managing the herd’s environment offer substitutes for antibiotics use. Organic milk carries

This study jointly estimates the impact of school quality and school proximity on residential property values in Greenville, South
Carolina. While quality is found to be capitalized into residential property values, the degree of capitalization depends on school
level and proximity to each school for which the house is zoned for attendance. In general, there is positive value associated with
closer proximity to schools of all levels, and negative value associated with a significantly longer than average distance to schools.
In terms of quality rankings, excellence at the elementary and high school levels has the strongest impact on property values.

The purpose of this paper has been to present quality-adjusted values for land in the United States and nine European countries
using price and quantity data for 1990. Disregarding such differences in the quality-adjusted land input would generate biased
estimates of the land input and thus of total factor productivity. Land quality adjustments could potentially be enhanced further
with additional data on soil characteristics, climate, and other productivity-related characteristics.

We develop a dynamic soil quality model to evaluate optimal cropping systems in the northern Great Plains. Modeling soil quality
attributes is feasible, and attribute model results apply to a wide range of soils. A crop production system with continuous spring
wheat and direct planting is the most profitable system. This system has low soil erosion and high quality attributes, indicating the
benefits of increased soil quality exceed the higher maintenance costs. On-site value of additional soil organic carbon (OC) ranges
from $1 to $4/ton OC/hectare/year. These values for soil OC impact the optimum tillage practice, but not the crop rotation.

This study estimates the impact of school quality on property values within the city limits of Greenville, South Carolina. This
study differs from others in its use of a relative, rather than an absolute measure of school quality. We apply a hedonic pricing
model to estimate the impact of K-12 rankings on the real constant-quality housing values. Based on 3,731 housing transactions
carried out from 1994 to 2000, our results suggest that those who choose to live within the city limits of the study pay a premium
to live in high quality school attendance areas. Therefore, high-ranked schools have values capitalized into single-family house
prices. Further, greater distance to assigned K-12 schools has a negative impact on the value of the property.

Estimation of the benefits of research using changes in producer and consumer surplus following a research-induced shift in the
supply curve provides a useful framework for the analysis of new wheat varieties. However, the framework assumes an
homogeneous product, which is not the case for wheat where there are changes in quality as a result of research. This aspect is
particularly important where there is a trade-off between quality and yield, as in the case of a higher-yielding, but lower-quality
wheat variety. The aim of this paper is to incorporate these quality aspects into an analysis based on a partial equilibrium
framework by separating the wheat market into segments based on wheat quality. A change in the type of wheat produced can

In a duopoly industry with environmentally differentiated products, we examine the effects of introducing a mandatory
environmental quality standard on firms'’ environmental quality choices, profits, and the average environmental quality offered
by the industry. We show that at low standard levels, both firms choose to overcomply regardless of the standard level. At
intermediate levels, the mandatory standard can reduce the profit of the low-cost firm while increasing that of the high-cost firm,
and that it can lower the industry’'s average environmental quality below what it would be without the standard.

Beef industry data suggest that improvements in carcass yield and quality grades have stagnated recently. Empirical analysis,
based on USDA market reports, indicates that the share of steer slaughter volume marketed on a grid is less than industry
estimates and the growth in market share has stagnated. Trend analysis of market share suggests that grid pricing has become an
important marketing channel, but has not become the dominant marketing channel. The lack of industry progress toward
achieving the carcass quality goals suggests that grid pricing has not captured the level of market share needed to realize the goals
envisioned for it as a value based marketing system

Mark.
There is a common perception that healthy food costs more than less healthy food. In this study we use a demand model for diet
quality, rather than the quantity of food. Since in our data, total daily cost and diet quality are both calculated from the foods
chosen, we account for the fact that cost is endogenous. We find that while total daily food cost is statistically significant in
relation to diet quality, the degree of association is very small. Hence, it does not appear that cost alone prevents individuals in the
United States from purchasing a healthy diet. Other factors such as food culture and environment, health behaviours, and
demographics are more important. Our findings suggest that the choice to consume a healthy diet is very complicated.

We propose a structural empirical approach à la Levinsohn and Petrin (2003) to disentangle the effect of experts’ grades from the
effect of unobserved quality on the pricing of experience goods. Using a panel data set of 108 châteaux selling wine on the
Bordeaux ‘en primeur’ market, we provide some empirical validation for the theoretical result that the price set by wine
producers is used as a signal for wine quality. We confirm that experts’ grades affect producers’ choice of ‘en primeur’ price
above the effect of unobserved wine quality. Our empirical results also show that failing to control for endogeneity caused by the
omission of unobserved leads to over-estimate the influence of experts’ grades on the ‘en primeur’ price.

Grid pricing improves the flow of information to producers, but market signals sent by grids may not be clearly understood. This

to identify market signals sent by grid pricing. Weight sends a stronger market signal than carcass quality characteristics such as
quality and yield grade. Although grids are shaping production, market signals indicate that lower quality carcasses are penalized
more than higher quality carcasses are rewarded. Sensitivity analyses suggest changes in quality and yield grade discounts have
the greatest impact on market signals.

This paper develops a double-sided moral hazard model of share contract in agriculture, with imperfect quality measurement by
the agent and the principal, who contribute to the final good quality in terms of production effort and marketing effort
respectively. Using this model, we analyse the implications of the share contract for quantity and quality, often ignored in
previous analysis. With the help of a simulation exercise, we prove that the outcome-conditioned share generally weakens the
agent´s incentive to make effort in quality input. This finding could explain the contractual evidence in some differentiated
markets such as the wine market, where bottle-price conditioned contracts are rarely used.

The objective of this study is to identify demands of customers of a sire-producing company in Rio Grande do Sul, Brazil, by
using a methodology adapted from quality function deployment tool. The adaptation consisted on the fact that matrices are treated
in an unified manner among product and services due to the high perception of inter-relationship among these business
components. The results evidenced that clients priorize traits related to the product, especially genetic value of the bulls. Service
items were also highlighted, and they may be presented as an opportunity of differentiation among suppliers. Customer profile
influenced priority order inasmuch as farmers with no technical services prioritized performance traits over genetic traits,

Aerobic deterioration influences the fermentative, microbiological and nutritional quality of maize
and sorghum silages on farm in high quality milk and cheese production chains
Provedor de dados: 96
Autores: Borreani,Giorgio; Bernardes,Thiago Fernandes; Tabacco,Ernesto.
Maize and sorghum silages are good sources of energy for lactating dairy cows that produce milk destined for fresh and matured
cheeses. Silages are usually stored in horizontal silos with or without side walls on commercial farms throughout the world. The
main microbiological and nutritional quality problems are related to harvesting time, ensiling technology, and management
practices during filling and feed-out. Aerobic deterioration is a key point that must avoided on farms in order to improve the
hygienic, chemical and sensorial quality of milk and cheeses. Aerobic deterioration causes large losses of dry matter (DM) and
quality, and it can cause health problems for animals and humans through the transfer of pathogens and mycotoxins from feed
and...

Assimilation efficiency in Bufo spinulosus tadpoles (Anura: Bufonidae): effects of temperature, diet
quality and geographic origin
Provedor de dados: 97
Autores: BENAVIDES,A. GONZALO; VELOSO,ALBERTO; JIMÉNEZ,PAULINA; MÉNDEZ,MARCO A.
The assimilation efficiency of Bufo spinulosus tadpoles from four localities in Chile was evaluated for two different temperatures
(15 and 25 ºC) and two different diets (low nutritional quality diet (LQD): 22.28 mg g N-1; high nutritional quality diet (HQD):
47.53 mg g N-1) using ash as a marker of digestion. Results showed that geographic origin did not affect assimilation efficiency,
while the relationship observed between temperature and diet quality was significant. Assimilation efficiency was greater for the
HQD when tadpoles were maintained at 15 °C, instead significant differences were not found between diets for tadpoles
maintained at 25 °C. Our results suggest that the effect of temperature on digestive processes is more relevant than its effect...

Soil loss expectation and possible relationships among soil erosion, riparian vegetation and water quality were studied in the São
José dos Dourados River basin, State of São Paulo, Brazil. Through Geographic Information System (GIS) resources and
technology, Soil Loss Expectation (SLE) data obtained using the Universal Soil Loss Equation (USLE) model were analyzed. For
the whole catchment area and for the 30 m buffer strips of the streams of 22 randomly selected catchments, the predominant land
use and habitat quality were studied. Owing mainly to the high soil erodibility, the river basin is highly susceptible to erosive
processes. Habitat quality analyses revealed that the superficial water from the catchments is not chemically impacted but

Relationship between seed technology research and federal plant breeding programs
Provedor de dados: 63
Autores: Krzyzanowski,F. C.
This paper deals with the contributions seed technology can provide for soybean breeding programs for seed quality. Efforts can
be placed on seed quality assurance (DIACOM) to assist the production system, from genetic up to certified seed in releasing a
product of high quality. Another approach is the development of screening methods, based on seed technology tests (vigor tests),
for selecting genotypes according to different traits relating to seed quality. An understanding of seed quality mechanisms, such as
seed-coat properties, pod-wall permeability, seed and pod resistance to fungi infection , seed shriveling and cell wall permeability,
will help to define the screening procedures for this characteristic. It has been one of the most important...
