CALL FOR PAPERS AND SESSION PROPOSALS The International Network for Social Network Analysis (INSNA) welcomes proposals for individual papers and paper session organizers for the next Sunbelt social network conference, which will take place at the island of Corfu, May 1-6, 2007. The conference web site is <http://nicomedia.math.upatras.gr/conf/Sunbelt2007/>. The conference provides an interdisciplinary venue for sociologists, psychologists, social and behavioral scientists, economists, political scientists, scholars in social movements, environmental studies, communication studies, STS, management and organizational studies, mathematicians, computer scientists, anthropologists, ethnologists, and others to present current work in the area of social networks. Proponents are invited to submit their paper titles and abstracts at the web page <https://cgi.sfu.ca/~insna/confpapers/> (full papers are not requested) until January 30, 2007. The name of the intended session can be specified by proponents themselves. However only those sessions will be actualized which contain more than five accepted papers. The process of evaluation of submitted papers will be finalized in February 2007. Questions about the conference should be sent to Moses Boudourides (sunbelt.corfu.2007@gmail.com).
