Sign up for this to learn the basics of network analysis next semester through online classes. I will deliver 2 of the 10 sessions. Not sure how to start with your network analysis project? This is the right place. We have some of the leading SNA folks here at Manchester. #polisky #publicpolicy #sna

How many of them reproduce observed macro-level emergent properties when simulated from the micro level? The "credibility revolution" will only be complete once generative emergence has been added as a requirement for empirical work.

Ideas don't simply appear and disappear in political debates. They evolve, transform and sometimes return in new forms. New in JCMS: Philip Leifeld and Kristijan Garic explore how framing contests change over time. Read more: onlinelibrary.wiley.com/doi/10.1111/... #JCSM #UACES #Wiley
Promotional graphic for a new JCMS article. The graphic features the headline “How Do Political Debates Change Over Time?” with the subtitle “Tracking the changing narratives that shape political debate.” A network-style visual of interconnected nodes appears in the top right. Three key patterns identified by the study are highlighted with icons: gradual shifts, sudden transformations, and re-emerging narratives. A quote from the article states: “Political debates are shaped by shifting ways in which actors frame problems and solutions.” The graphic is branded with the JCMS and UACES logos and a badge reading “New in JCMS.”

Separate investment networks between General Partners (GP) and Limited Partners (LP) for five different asset classes (private equity, private debt, real estate, natural resources, and infrastructure) and one combined ("hybrid") network. Each of the six networks has thousands of nodes and a typical Fruchterman-Reingold network layout.
