***** To join INSNA, visit http://www.insna.org ***** On the homophily question 1. Barry Wellman and Milena Gulia have a chapter that tests the effects on social support in personal networks of a bunch of things, including homophily. Our finding was that homophily didn't predict much to the amount of support floating around thru a network. It's "The Network Basis of Support" in Barry Wellman, ed., _Networks in the Global Village_. (Boulder, CO: Westview, 1999). 2. However, when Ken Frank and I applied multilevel analysis to the same data, we found some potentiating effects of homophily. That is ties of a certain kind were apt to be supportive when they were in a personal network that had a relatively high percentage of similar other ties. My favorite was the mother-in-law effect (altho, drats, we didn't call it that in the paper): parent-adult child ties were more supportive when there was more than one such tie. This is one of my favorite papers (thanks Ken), as it also sets up Simmel vs Homans on the emergent properties issue. It's available in the Lin-Cook-Burt Social Capital reader, and also on my website in slightly prelim form. Here's the title and abstract from my website: "Network Capital in a Multi-Level World: Getting Support from Personal Communities." In Social Capital: Theory and Research, edited by Nan Lin, Karen Cook and Ronald Burt. Chicago: Aldine DeGruyter, 2001. [On the methodological side, combines tie-level and network-level analyses of social support in East York. On the substantive side, provides better analysis of the data examined in "The Community Question" and "Different Strokes ..." (above). On the theoretical side, shows that individual agency, interpersonal duets, and network processes all affect the provision of social support.] Barry _____________________________________________________________________ Barry Wellman Professor of Sociology NetLab Director wellman at chass.utoronto.ca http://www.chass.utoronto.ca/~wellman Centre for Urban & Community Studies University of Toronto 455 Spadina Avenue Toronto Canada M5S 2G8 fax:+1-416-978-7162 You're invited to visit -- and contribute to -- my new fun website "Updating Cybertimes: It's Time to Bring Our Culture into Cyberspace" http://chass.utoronto.ca/oldnew/cybertimes.php _____________________________________________________________________ _____________________________________________________________________ SOCNET is a service of INSNA, the professional association for social network researchers (http://www.insna.org).
