The Paradox of the Paradox of Friends: Implications for Social and Organizational Change
Ever since Scott Feld's classic 1991 paper, it has been established that, on the average, we find our friends have more friends than we do.  This principle has been called The Friendship Paradox, and it has implications for many social phenomena, including innovation diffusion and organizational change.  Indeed, a group from Yale's Institute for Network Science (2022) has found that they could substantially influence the adoption rate of healthy practices in a community by leveraging this friendship paradox principle.  However, we have discovered that this paradox itself leads to a further paradox, suggesting, with a nod to Schroedinger's cat, that the original principle is mathematically both true and not true at the same time in the same network.  This result leads us to new strategies for innovation that have the potential for substantially improving the odds of success in any systemic change effort.

Case Studies and Tools for Geographic Social Network Analysis
Social networks often have a geospatial dimension, yet social network analysis is often conducted without considering the location of nodes and the context of the network. In this talk, I'll describe how geographic information systems (GISystems/GIS) can help users analyze social networks through two different case studies: a food sharing network in Southwestern Virginia and a historical network of the U.S. Mafia. I will also demonstrate new tools in the R statistical computing environment, a new standalone software called SNoMaN that can be used to facilitate the analysis of social networks, and a brief tutorial in QGIS.
