Mitchell Centre Seminar Series, Alessandro Lomi (University of Italian Switzerland, Lugano) Modeling Social Networks with Changeable Nodes
16:00 - 17:30 18 February 2026
One of the defining features of social networks is that their nodes—social agents—are not fixed entities but actively reconfigure their internal structure in response to changes in their environment. When such reconfiguration occurs, widely held assumptions about mechanisms of network formation,...

Mitchell Centre Seminar Series. Kasimir Dederichs (University of Oxford) Join to connect? Voluntary involvement, social capital, and socioeconomic inequalities.
16:00 - 17:30 11 February 2026
Access to social capital is stratified by socioeconomic status and has been cross-sectionally linked to involvement in voluntary organizations. Yet, we know little about the origin and interplay of these empirical regularities. Regression analyses on German panel data (SC6-NEPS) reveal that people...

Mitchell Centre Seminar Series Martin Everett (Manchester) Assessing eigenvector type centrality for disconnected graphs.
16:00 - 17:30 4 February 2026
Eigenvector centrality (Bonacich 1972) is one of the most used centrality measures in social network analysis. When applied to disconnected graphs, it typically assigns non-zero values only to nodes in the component with the largest eigenvalue, with all other nodes receiving zero. The usual solution...

Mitchell Centre Seminar Series - Scott Duxbury (University of North Carolina, Chapel Hill) - General Procedures for Micro-Macro Network Analysis
15:00 - 16:30 10 December 2025
How do interpersonal social interactions generate novel network structures? Historically researchers examined micro-macro linkages in social networks using simulation approaches, especially empirically calibrated agent-based models grounded in generative models for network structure. The research presentation...

Mitchell Centre Workshop: Agent-Based Modelling with a Focus on Network Analysis
10:00 - 13:15 3 December 2025
The workshop starts with an introduction to agent-based modelling using Netlogo. It then focuses on ABM for social network data, touching upon the possibilities and limitations of ERGMs and SAOMs, as well as other approaches to use ABMs for social network data. The workshop ends with a discussion of...

Mitchell Centre Seminar Series - Federico Bianchi & Francesco Renzini (University of Milan) - Agent-Based Modelling for Social Network Research: Two Examples
16:00 - 17:30 3 December 2025
The seminar will be centred on Agent-Based Modelling (ABM) as a strategy for modelling social networks while avoiding some of the pitfalls of standard statistical models. Because of its high flexibility, ABM allows researchers to model the formation of social ties and the influence that ties exert on...

Mitchell Centre Seminar Series - Tobias Stark (Utrecht University) - Effects of Identity Signals on the Perception of 2nd Generation Immigrants’ Integration in Social Networks
16:00 - 17:30 26 November 2025
The majority of 2nd generation immigrants in Western Europe identify both with the ethnic group of their parents and with the national majority group. Yet their belonging to the national group is often not recognized. Descendants of immigrants are, for instance, labelled “Turks” or “Moroccans”...

Mitchell Centre Seminar Series - Bernie Hogan (Oxford University) - Perspective Matters: Egocentric Networks and the Bundling/Grinding Problem in Sheaf Theory
16:00 - 17:30 19 November 2025
Consider a whole network, such as a classroom. Each student can create an egocentric network visually and in metric space through traditional methods. Yet the aggregation of these networks remains a nontrivial problem. The conventional solutions, often treated under the rubric “Cognitive Social Structures”...

Mitchell Centre Seminar Series - Joe Labianca (University of Massachusetts at Amherst) - Affect’s Role in Organizationally-Sponsored Networking
16:00 - 17:30 12 November 2025
Most organizational research on networking focuses on negative emotions toward it; but some people are comfortable with networking or even find it energizing. This mixed methods study draws upon the more comprehensive circumplex model of affect to investigate how positive and negative emotions experienced...

Mitchell Centre Seminar Series - Lars Leszczensky (Goethe University Frankfurt) - Gendered Mechanisms of Social Segregation Among Muslim Youth
16:00 - 17:30 29 October 2025
This talk will present findings from an ongoing research project on why friendships between Muslim and non-Muslim adolescents are relatively rare. The focus is on gender-specific processes of religious segregation within friendship networks. A key question is whether religious segregation stems from...
