Cybergeo, 2016 This paper examines the driving forces of urban network formation through the simulation of inter-city transport networks in Southeast Asia. We present a generative network model (GNM) considering geographical and topological effects, thus combining ...

Stochastic actor oriented model with random effects
Social NetworksThe stochastic actor oriented model (SAOM) is a method for modelling social interactions and social behaviour over time. It can be used to model drivers of dynamic interactions using both exogenous covariates and endogenous network configurations, but also the co-evolution of behaviour and social interactions.

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.

SSRN Electronic Journal, 2020 Abstract This study aimed to examine whether adolescents select friends based on their friends’ levels of depressive symptoms, and to determine whether the potential homophily phenomenon for depressive symptoms is attenuated after considering pubertal maturation and gender.

Sinister connections: How to analyse organised crime with social network analysis?
Acta Universitatis Carolinae: Philosophica et Historica, 2018 Networks have recently become ubiquitous in many scientific fields. In criminology, social network analysis (SNA) provides a potent tool for analysis of organized crime.

SSRN Electronic Journal, 2022 The globalization of trade has caused tremendous pressure on water resources globally, and a virtual water trade provides a new perspective on global freshwater sharing and water sustainability. No study has yet explored the structural characteristics and drivers of the evolution of global virtual water trade networks from a network structure evolution

Education SciencesBoth interests and peer relations are crucial for adolescents in finding out who they are and want to be as a person. Yet, our knowledge of the co-evolution of friendships and interests is limited to studies focusing on single interest domains and/or ...

Belgeo, 2016 This paper explores the urban-geographical potential of simulation approaches combining spatial and topological processes. Drawing on Vértes et al.'s (2012) economical clustering model, we propose a generative network model integrating factors captured ...

Application of the Dynamic Latent Space Model to Social Networks with Time-Varying Covariates
ComputationWith the growing accessibility of tools such as online surveys and web scraping, longitudinal social network data are more commonly collected in social science research along with non-network survey data.
