Assessing and accounting for time heterogeneity in stochastic actor oriented models [PDF]
Advances in Data Analysis and Classification, 2010 This paper explores time heterogeneity in stochastic actor oriented models (SAOM) proposed by Snijders (Sociological Methodology. Blackwell, Boston, pp 361-395, 2001) which are meant to study the evolution of networks. SAOMs model social networks as directed graphs with nodes representing people, organizations, etc., and dichotomous relations ...

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.

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

Insight into Selecting Adolescents for Drinking Intervention Programs: a Simulation Based on Stochastic Actor–Oriented Models [PDF]
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.

Envisaging the Unobserved: a Stochastic Actor-Oriented Model for Systems of Overlapping Subgroups
This paper presents a novel statistical framework for modeling cohesive subgroups in cross-sectional network data, adhering to prior ideas about the mean and variance of the number of actors per subgroup and subgroups per actor. Subgroups emerge from actors' membership decisions, with cohesion driven by their preference to co-member with network ...

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.

Stochastic Actor-Oriented Models of Functional and Structural Human Brain Networks in Aging
The human brain is a complex and dynamical system that changes throughout the lifetime. Non-invasive imaging techniques, including magnetic resonance imaging (MRI), allow for the measurement of large-scale functional and structural connectivity networks in the brain. Beyond trends, the dynamics across long timescales are still poorly understood.

The Role of Cognitive Emotion Regulation for Making and Keeping Friend and Conflict Networks
Frontiers in Psychology, 2022 We used social network analysis (SNA) to examine how adaptive ER strategies (acceptance, positive reappraisal, refocusing, and putting in perspective) and maladaptive ER strategies (rumination, catastrophizing, self- and other-blame) predict the creation
