Analysis of the Driving Mechanism of China’s Provincial Carbon Emission Spatial Correlation Network: Based on the Dual Perspectives of Dynamic Evolution and Static Formation

Systems
Against the backdrop of China’s commitment to achieving carbon peaking by 2030 and carbon neutrality by 2060, inter-provincial carbon emissions form a complex interconnected spatial network—clarifying its operational mechanisms is crucial for optimizing ...

Peer influence in adolescent drinking behaviour: a protocol for systematic review and meta-analysis of stochastic actor-based modeling studies

BMJ Open, 2019
Introduction Alcohol consumption is a considerable public health problem that is especially harmful to young people. To develop effective prevention programmes targeted at adolescents, it is important to understand the social mechanisms triggering ...

Friendship as a social mechanism influencing body mass index (BMI) among emerging adults.

PLoS ONE, 2018
BACKGROUND:Social relationships have been proposed as a significant factor shaping obesity risk. The first year of college, a period of major social, behavioral, and weight changes, provides a context well-suited to tracking longitudinally the impact of ...

Why do countries engage in the preferential trade agreement network?

Revista de Economía y Estadística
We analyze the determinants of Preferential Trade Agreements Networks dynamics. We propose a theoretical framework based in an extension of Baldwin (1995) to rationalize the determinants of PTA formation as a way to maximize preferential market access ...

Adolescent Depressive Symptoms and Peer Dynamics: Distorted Perceptions in Liking and Disliking Networks

Behavioral Sciences
Depression in adolescents has been linked to poor life outcomes, including suicidal ideation, peer victimization, and fewer friendships. Less is known about how depressed adolescents perceive their peer interactions.

Sociocultural mechanisms of conflict: Combining topic and stochastic actor-oriented models in an analysis of Afghanistan, 1979–2001

Poetics, 2019
How do sociocultural dynamics shape conflict? We develop a relational understanding of how social relations, culture, and conflict are interwoven. Using this framework, we examine how combatants' associations with cultural elements affect the interpersonal relationships underlying conflict dynamics, as well as how these relationships engender ...

Evolution of Project-Based Collaborative Networks for Implementing Prefabricated Construction Technology: Case Study in Shanghai

Buildings
Prefabricated construction (PC) is considered to be a low-carbon construction method. Implementing prefabricated construction projects (PCPs) requires multiple industry organizations to participate and collaborate.

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 ...

An Empirical and Simulation Investigation of Bounded Confidence and Negative Influence in Opinion Dynamics Using Stochastic Actor-Oriented Model

Journal of Artificial Societies and Social Simulation
Bounded confidence and negative influence are two of the most important micro-level mechanisms employed in computational models of opinion dynamics to explain polarization of opinions. However, empirical evidence of both mechanisms is debatable. Two common limitations in existing empirical studies are (1) the limited external validity of laboratory ...

Estimation of stochastic actor-oriented models for the evolution of networks by generalized method of moments.

Journal de la Société Française de Statistique, 2015
The stochastic actor-oriented model (Snijders, Sociological Methodology, 2001) models the evolution of networks over time, given panel data in a fixed group of actors, where at each panel wave the network between these actors (a digraph structure) as well as attribute variables for these actors are observed.
