  8. Identifying Locals:Data / First Empirical Evidences From a Large Data Set • Freshmen population of N=182 students over the first 9 weeks at University of Wuppertal/Germany (1978/79; Humell & Sodeur) • Identification of Local roles by means of the proposed instrument (Täube, 2002) in the socio-emotional and in the instrumental network • Comparing the number of identified Local brokers with numbers obtained if number of occurences would be purly random / Expectation: Number of identified broker roles should deviate significantly from numbers obtained randomly. • Comparisons within weeks (testing for plausibility of general appearance) and between weeks (testing for stability of Local roles over time)

  9. First Empirical Evidence From a Large Data Set (Example):Comparison of Local identification in socio-emotional and instrumental network in week no 9. Instrument identified 6 identical Locals appearing in both networksTables show random probabilities for number of occurences

  10. First Empirical Evidence From a Large Data Set (Example):Comparison of Local identification in socio-emotional network between week no 8 and 9. Instrument identified 6 identical Locals appearing in both weeksTables show random probabilities for number of occurences

  11. Social Capital and the Evolution of Social Structures • First results look promising • A more elaborated baseline model needs to be developed and tested for to take also Cosmopolitans into account • All steps of the identification procedure should be automated • References: • Burt, Ronald S. 1990. « Detecting Role Equivalence »; in: Social Networks, Nr.12. • Gould, Roger V, & Fernandez R.
