Accounting for edge uncertainty in stochastic actor-oriented models for dynamic network analysis. [PDF]
Netw Sci (Camb Univ Press)Abstract Stochastic Actor-Oriented Models (SAOMs) were designed in the social network setting to capture network dynamics representing a variety of influences on network change. The standard framework assumes the observed networks are free of false positive and false negative edges, which may be an unrealistic assumption.

Applied Network Science, 2021 Evidence from 184 countries over the span of 25 years is gathered and analyzed to understand North–North, South–South, and North–South international migration flows. Conceptually, the analysis borrows from network theory and Migration Systems Theory (MST)

SSM: Population Health, 2021 Adolescents who feel depressed are likely to experience social isolation from friends. Previous studies have put forward at least four hypotheses that can account for the association between felt depression and social isolation.

Analysing animal social network dynamics: the potential of stochastic actor‐oriented models [PDF]
Journal of Animal Ecology, 2017 Summary Animals are embedded in dynamically changing networks of relationships with conspecifics. These dynamic networks are fundamental aspects of their environment, creating selection on behaviours and other traits. However, most social network‐based approaches in ecology are constrained to considering networks as static, despite several calls for

A theoretical and empirical comparison of the temporal exponential random graph model and the stochastic actor-oriented model [PDF]
Network Science, 2019 AbstractThe temporal exponential random graph model (TERGM) and the stochastic actor-oriented model (SAOM, e.g., SIENA) are popular models for longitudinal network analysis. We compare these models theoretically, via simulation, and through a real-data example in order to assess their relative strengths and weaknesses.

Some Birds Have Mixed Feathers: Bringing the Multiracial Population into the Study of Race Homophily
Sociological ScienceResearch on race homophily in the United States has yet to meaningfully include the growing multiracial population. The present study confronts this challenge by drawing upon recent conceptualizations of race as a multidimensional construct.

Prevention Science, 2021 Adolescent drinking remains a prominent public health and socioeconomic issue in the USA with costly consequences. While numerous drinking intervention programs have been developed, there is little guidance whether certain strategies of participant recruitment are more effective than others.
