294 Appendix A Music mixing elements of improvisation and composition were included, as were several concerts involving improvisation that might be considered on the borders of Improvised Music - bands such as The Still and Transmit (which border on pop/rock), concerts at Jazzkeller69 or Jazz an der LohmuÌhle (which border on more mainstream jazz), and performances by the Wandelweiser group (bordering on Neue Musik or contemporary classical music). Venues hosting several nights with different names and promoters, such as Le Petit Mignon (which happened in Quiet Cue) and Basic Electricity, Salon Bruit, AUXXX and K77 Studio (which all took place in the Lichtblick Kino) were all collated by venue. The database of venues also collected address information in order to generate the map shown on Page 95. Importing into UCINET This data was then imported into UCINET [Borgatti et al., 2002] using âPilesâ (1-mode network) and âNodelist 2â (2-mode network) import options, later adding the Musicians database as attributes and using UCINET to generate centrality, homophily and ego network constitution data, as well as produce the diagrams shown in Chapter 5. All numerical results were error corrected (missing values omitted). In order to calculate measures for the 2-mode network (not directly possible using the 2-mode functions of UCINET), the file was converted to a 1-node network containing both venues and participants, with attributes for each venue left blank so as not to affect the outcome. This was something of a get-around to calculate ego net composition for the venues themselves, which works because UCINET does not include the ego itself in its analysis. Musicians Biographical data was collected from musiciansâ websites, Facebook, Soundcloud and Myspace accounts, and online biographies (used for concert promotion), to create an attribute database for SNA and to identify basic demographics of the scene. Where possible, data was cross-checked against as many sources as possible, and musiciansâ own websites, Myspace and Soundcloud accounts were prioritised over concert listings and Wikipedia entries (deemed less reliable). Where no information was available fields were left blank, however, in a few cases (and where I knew participants personally) dates of birth and arrival in Berlin were estimated. I estimate these dates to be correct within 1 year, and these values are marked with an asterix in the âSourceâ column of the SPSS file.
