Statistical Models for Analysis of Social Network Dynamics in Educational Studies

Вопросы образования, 2015
Research on co-evolution of networks and behavior became possible with the emergence of student performance and behavior dynamic data collection and storage tools, as well as with the development of new social network analysis methods.

The evolution and co-evolution of a primary care cancer research network: From academic social connection to research collaboration.

PLoS ONE, 2022
Academic networks are expected to enhance scientific collaboration and thereby increase research outputs. However, little is known about whether and how the initial steps of getting to know other researchers translates into effective collaborations.

Neither influence nor selection: Examining co-evolution of political orientation and social networks in the NetSense and NetHealth studies.

PLoS ONE, 2020
Political orientation is one of the most important and consequential individual attributes studied by social scientists. Yet, we know relatively little about the temporal evolution of political orientation, especially at periods in the life course during

Generative network models for simulating urban networks, the case of inter-city transport network in Southeast Asia

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 ...

A Longitudinal Network Analysis of the German Knowledge Economy from 2009 to 2019: Spatio-Temporal Dynamics at the City–Firm Nexus

Journal of Social Structure, 2020
Multi-location knowledge-intensive firms span their value chains and thus their locations across space. Increased globalization alters the spatial configuration of such networks of knowledge creation. Longitudinal social network analysis allows detecting

Introduction to stochastic actor-based models for network dynamics [PDF]

, 2010
Stochastic actor-based models are models for network dynamics that can represent a wide variety of influences on network change, and allow to estimate parameters expressing such influences, and test corresponding hypotheses.
