Relative importance of effects in stochastic actor-oriented models [PDF]
Network Science, 2013 AbstractA measure of relative importance of network effects in the stochastic actor-oriented model (SAOM) is proposed. The SAOM is a parametric model for statistical inference in longitudinal social networks. The complexity of the model makes the interpretation of inferred results difficult. So far, the focus is on significance tests while the relative

Stochastic actor-oriented models for the co-evolution of networks and individual outcomes
Stochastic actor-oriented models (SAOMs) originated as models to explain network evolution over time. They have been extended in several directions. This chapter focuses on the extension of SAOMs for analyzing the co-evolution of networks and individual outcomes, such as behaviours, attitudes, and activities.

JasssBounded confidence and negative influence are two of the most important micro-level mechanisms employed in computational models of opinion dynamics to explain polarization of opinions. However, empirical evidence of both mechanisms is debatable. Two common limitations in existing empirical studies are (1) the limited external validity of laboratory ...

The dynamics of intergenerational closure and family networks of social cohesion
Frontiers in Sociology, 2023 We investigate the correlation of ties among school-children's parents with violence in schools, and two mechanisms of intergenerational closure (IC). Coleman described ties among parents of befriended children as IC.

Social Support and Network Formation in a Small-Scale Horticulturalist Population
Scientific Data, 2022 Evolutionary studies of cooperation in traditional human societies suggest that helping family and responding in kind when helped are the primary mechanisms for informally distributing resources vital to day-to-day survival (e.g., food, knowledge, money,
