  • Birds of a feather at first sight: Decomposing homophily into tie formation and persistence

    Open Access•Thomas U Grund•ARTICLE•Social Networks•2026

    Why do some social ties endure while others dissolve? Homophily research typically treats similarity as a single mechanism, conflating processes of tie formation and persistence. I develop a framework based on attribute observability, distinguishing between observable characteristics that guide formation under uncertainty and interaction-revealed attributes that shape tie retention. Using three-wave longitudinal friendship network data and Stocha…

  • One body, many identities: A mathematical model of multidimensional segregation dynamics

    Open Access•Thomas U Grund•ARTICLE•Journal of Mathematical Sociology•2026

    Individuals inhabit multiple social roles – citizen, neighbor, worker – but make residential decisions with a single body. Classic segregation models assume fixed, singular identities. This paper extends Schelling’s model by introducing agents with multidimensional identities and salience rules that determine which identity guides behavior. Across 1,920 simulations, we show that coordination failures produce persistent dissatisfaction and instabi…

  • Evolving homophily in higher education: How university settings transform international student relationships

    Open Access•Thomas U Grund, Aisling Tiernan et al.•ARTICLE•British Journal of Sociology of…•2026

    Homophily research traditionally examines which similarities predict tie formation. This study extends this perspective by investigating how the foundations of homophilous relationships evolve over time through sustained institutional interaction. Drawing on in-depth interviews with international students at a German university, we analyse how educational settings enable relationships—initially grounded in one similarity (e.g. nationality, langua…

  • Social Media Use and Adolescent Depressive Symptoms: The Moderating Roles of Gender and Parental Monitoring

    Open Access•Thomas U Grund, Heike Krüger et al.•ARTICLE•International Journal of Mental…•2025

    Social media use has significantly reshaped adolescents’ social experiences, raising substantial concerns about its impact on mental health. This study examines the association between social media usage intensity and depressive symptoms among adolescents, emphasizing the moderating roles of parental monitoring and gender. Using logistic regression analysis of the 2023 US Youth Risk Behavior Survey ( N = 10,334), results reveal that moderate and …

  • Modeling Diffusion through Statistical Network Analysis: A Simulation Study and Empirical Application to Same-Sex Marriage

    Open Access•Johan A Elkink, Thomas U Grund•ARTICLE•International Studies Quarterly•2022•Cited by: 3•References: 70

    The study of international relations by definition deals with interdependencies among countries. One form of interdependence between countries is the diffusion of country-level features, such as policies, political regimes, or conflict. In these studies, the outcome variable tends to be categorical, and the primary concern is the clustering of the outcome variable among connected countries. Statistically, such clustering is studied with spatial e…

  • Accusation and confession discrepancies in bullying: Dual-perspective networks and individual-level attributes

    Open Access•Travis Tatum, Travis G Tatum et al.•ARTICLE•Social Networks•2020

  • Role of Narrative and Social Networks in Thwarting Violence and Sexual Abuse in Young People’s Lives

    Open Access•Margareta Hydén, D Gadd et al.•ARTICLE•The British Journal of Social Work•2020•References: 21

    Combining narrative analysis with social network analysis, this article analyses the case of a young Swedish female who had been physically and sexually abused. We show how she became trapped in an abusive relationship at the age of fourteen years following social work intervention in her family home, and how she ultimately escaped from this abuse aged nineteen years. The analysis illustrates the significance of responses to interpersonal violenc…

  • Some friends matter more than others: BMI clustering among adolescents in four European countries

    Open Access•Thomas U Grund, Travis Tatum•ARTICLE•Network Science•2019•References: 32

    Previous research stresses the importance of social networks for obesity. We draw on friendship data from 18,133 adolescents in four European countries to investigate the relationship between individuals’ body mass index (BMI) and the BMI of their friends. Our study reveals strong evidence for BMI clustering in England, Germany, the Netherlands, and Sweden; adolescents tend to be friends with others who have a similar BMI. Furthermore, we extend …

  • Residential Segregation and 'Ethnic Flight' vs. 'Ethnic Avoidance' in Sweden

    Open Access•Tim S Müller, Tim Müller et al.•ARTICLE•European Sociological Review•2018•Cited by: 12•References: 55

    Residential segregation along ethnic categories has been associated with social disadvantages of minority group members. It is considered a driving factor in the reproduction of social inequalities and a pressing issue in many societies. While most research focuses on neighbourhood segregation in the United States, less is known about the origins of ethnic enclaves in European cities. We use complete data of residential moves within Stockholm mun…

  • Overlapping crime: Stability and specialization of co-offending relationships

    Open Access•Thomas U Grund, Thomas Grund et al.•ARTICLE•Social Networks•2017

  • The Relational Value of Network Experience in Teams: Evidence From the English Premier League

    Open Access•Thomas U Grund•ARTICLE•American Behavioral Scientist•2016•Cited by: 2•References: 55

    Previous studies indicate the importance of experience for the performance of teams. Theory suggests that working together allows individuals to (a) improve their knowledge about who knows (and can do) what and (b) facilitates learning to combine individual resources efficiently. Yet it remains elusive how experience translates into interaction patterns in teams. Drawing on unique data of career histories of 800 players and 283,259 passes between…

  • Why Your Friends Are More Important and Special Than You Think

  • Multidimensional homophily in friendship networks

    Open Access•Per Block, Thomas U Grund et al.•ARTICLE•Network Science•2014•Cited by: 50•References: 24

    Homophily—the tendency for individuals to associate with similar others—is one of the most persistent findings in social network analysis. Its importance is established along the lines of a multitude of sociologically relevant dimensions, e.g. sex, ethnicity and social class. Existing research, however, mostly focuses on one dimension at a time. But people are inherently multidimensional, have many attributes and are members of multiple groups. I…

  • Network Dynamics and Market Structure: The Case of Art Fairs

    Tamar Yogev, Thomas U Grund et al.•ARTICLE•Sociological Focus•2012•Cited by: 7•References: 22

    Annual art fairs are a crucial element of the contemporary art market. Art galleries represent artists and exhibit their work at fairs all over the world. These fairs expose the gallery and its artists and create and maintain relationships with key actors in the global art market. Using data recording artists and galleries presenting at art fairs alongside qualitative interviews with different actors operating in the art market, we study the deve…
