Team Kick-off Lecture
Getting Connected: Social Science in the Age of Networks
Michael Macy, Networks Team Leader
4:30-6:00 pm, 423 ILR Conference Center

We know far more about individuals and populations than we do about social interactions, which are fleeting, hard to observe, and tedious to record. All that is changing, thanks to the rapid growth of on-line networks, where social interactions leave a digital trace. Accordingly, we are planning a series of events next year to foster multi-disciplinary exchanges and highlight new opportunities for research on social and information networks, including those in cyberspace as well as off-line. Please join us for this kick-off lecture for the 2005-8 ISS theme project. Q & A with the research team members will follow the lecture.

Nov. 8-11, 2006 
Search and Diffusion on Social Networks
423 ILR Conference Center

The subject is social processes that occur on networks, with a focus on the directed and undirected transmission of information, practices, and behavior. Thematic issues include the identification and design of network structures that enhance search and diffusion, challenges in network measurement and inference, the mutual dynamics of network topologies and the material that passes over them, and variation in mechanisms across empirical domains.

March 28-31, 2007
Cornell Microsoft International Symposium on Self-Organizing Online Communities
423 ILR Conference Center

This three-day international workshop (with kickoff dinner and lecture on March 28), co-sponsored by Microsoft Research, will focus on communities in cyberspace, and in particular, on the dynamics of self-organization within these communities. The rapid growth of on-line communities (such as news groups, blogs, and wikis), opens up unprecedented possibilities to observe the recruitment process in real time, including the network structures through which it is mediated. These communities also represent research sites for the study of on-line governance and the emergence of norms and institutions. Accordingly, the workshop would examine the new research opportunities for studying social interactions that leave a digital trace. To that end, the workshop would introduce participants to a reconfigured relational database derived from the Internet Archive and hosted at Cornell as part of the NSF’s Next Generation Cyberinfrastructure Program.

Blurring the Boundaries: Collaborative Learning 
Jeff Hancock, Assistant Professor of Communication and Geri Gay, ISS Networks Team Member and Kenneth J. Bissett Professor & Chair, Communication
12:15-1:30 p.m., 225 ILR Conference Center
Faculty Innovation in Teaching Series
In their project, Jeff Hancock and Geri Gay sought to examine two general questions about collaborative learning and everyday technology. the first focused on examining how everyday technology that students use regularly (e.g., blogs) can be used to make student collaboration visible and public. The second examined how technology can guide dynamic reflection on collaborative skills and practices in an effort to improve student collaboration.

October 24
Pictures of Traces of Places, People, and Groups: Recent Work from the Microsoft Research Community Technologies Group
Lecture: 4:00-5:00 p.m., 340 Duffield Hall, Reception: 3:45-4:00 PM (Following the talk, the reception will continue from 5:00 – 5:15p);
Co-Sponsored by Cornell Information Science, Sociology, Communication and the ISS Networks Theme Project
The Microsoft Research Community Technologies group focuses on the study and enhancement of computer mediated collective action systems, now sometimes called social media or Web 2.0.  In this talk Marc will present recent developments in projects that highlight and attempt to enhance computer mediated collective action: Netscan, SNARF, S.L.A.M. and A.U.R.A.
