Visualization methods for longitudinal social networks and stochastic actor-oriented modeling [PDF]

Social Networks, 2012
Abstract As a consequence of the rising interest in longitudinal social networks and their analysis, there is also an increasing demand for tools to visualize them. We argue that similar adaptations of state-of-the-art graph-drawing methods can be used to visualize both, longitudinal networks and predictions of stochastic actor-oriented models (SAOMs),

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

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.

Stochastic actor oriented model with random effects

Social Networks
The 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.

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 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 Science
Research 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.

The Dynamics of Adolescents’ Pubertal Maturation, Depressive Symptoms and Friendship Networks: Stochastic Actor-Oriented Model

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.

Roll‐to‐Roll Mechanical Exfoliation for Large‐Area van der Waals Films with Preserved Crystallographic Alignment

Advanced Functional Materials, EarlyView.
A roll‐to‐roll exfoliation method is demonstrated that preserves the crystallographic alignment of anisotropic 2D materials over large areas, enabling scalable fabrication of directional electronic and optoelectronic devices. Abstract Anisotropic 2D materials such as black phosphorus (BP), GeS or CrSBr, exhibit direction‐dependent optical and ...

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.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.
