Friendship based on race or race based on friendship? The co-evoluation of friendships, negative ties and ethnic perceptions in Hungarian school classes by Boda, Z

“…<p>This thesis focuses on the dynamic interplay between race and social ties. Even though in sociological studies, race is usually treated as a cause of social segregation, we argue that this is a two-way process. …”

Maximum likelihood estimation for social network dynamics by Snijders, T, Koskinen, J, Schweinberger, M

“…A model for network panel data is discussed, based on the assumption that the observed data are discrete observations of a continuous-time Markov process on the space of all directed graphs on a given node set, in which changes in tie variables are independent conditional on the current graph. …”

A multilevel network study of the effects of delinquent behavior on friendship evolution by Snijders, T, Baerveldt, C

“…Similarity of the degree of delinquent behavior has a positive effect on tie formation but also on tie dissolution. The last result seems to contradict current criminological theories, and deserves further study.…”

Settings in social networks: A measurement model by Schweinberger, M, Snijders, T

“…The measurement model is based on two assumptions. (1) The observed network is generated by hierarchically nested latent transitive structures, expressed by ultrametrics, and (2) the expected tie strength decreases with ultrametric distance. …”

Circular specifications and “predicting” with information from the future: Errors in the empirical SAOM–TERGM comparison of Leifeld & Cranmer by Block, P, Hollway, J, Stadtfeld, C, Koskinen, J, Snijders, T

“…Finally, beyond these specific points, we argue that their evaluation metric—tie-level predictive accuracy—is unsuited for the task of comparing model performance. …”

Statistical Models for Social Networks by Snijders, T

“…Statistical models for social networks as dependent variables must represent the typical network dependencies between tie variables such as reciprocity, homophily, transitivity, etc. …”

Introduction to stochastic actor-based models for network dynamics by Snijders, T, van de Bunt, G, Steglich, C

“…The nodes in the network represent social actors, and the collection of ties represents a social relation. The assumptions posit that the network evolves as a stochastic process 'driven by the actors', i.e., the model lends itself especially for representing theories about how actors change their outgoing ties. …”

A situational understanding of friendship networks by Block, P

“…Starting from this proposition, I suggest that when two adolescents share one forum for interaction with one another, i.e. they regularly meet within one of the social situations, meeting in additional other situations does not increase the likelihood of a friendship tie existing as much as could be expected from the sum of the effect of meeting in either situation. …”

A Hierarchy of Preferences: A Longitudinal Network Analysis Approach to PTA Formation by Manger, MS, Pickup, M, Snijders, T

“…The findings suggest that PTAs spread endogenously because of structural arbitrage effects in the network, and that they establish a hierarchy among countries. Rich countries form ties with each other and middle-income countries, who themselves create a horizontal layer of PTAs, but least-developed countries are left behind and do not form many ties. …”

FRAME DECAY, INFORMAL POWER, AND THE ESCALATION OF SOCIAL CONTROL IN A MANAGEMENT TEAM: A RELATIONAL SIGNALING PERSPECTIVE by Wittek, R, van Duijn, MAJ, Snijders, T

“…Multilevel analysis indicates that strong ties between conflicting parties decrease the level of social escalation, whereas informal power advantage of one party increases the chances for social escalation. …”

Dynamics of adolescent friendship networks and smoking behavior: social network analyses in six European countries. by Mercken, L, Snijders, T, Steglich, C, de Vries, H

“…The main measurements were friendship ties, adolescents smoking behavior, parental smoking behavior, and sibling smoking behavior. …”

MCMC estimation for the p(2) network regression model with crossed random effects. by Zijlstra, B, Duijn, v, Snijders, T

“…It can be characterized as a multinomial regression model with crossed random effects that reflect actor heterogeneity and dependence between the ties from and to the same actor in the network. Three Markov chain Monte Carlo (MCMC) estimation methods for the p(2) model are presented to improve iterative generalized least squares (IGLS) estimation developed earlier, two of which use random walk proposals. …”

Why are some more peer than others? Evidence from a longitudinal study of social networks and individual academic performance by Lomi, A, Snijders, T, Steglich, C, Torló, V

“…At the same time, students attaining similar levels of academic performance are more likely to develop friendship and advice ties. Together, these results imply that processes of social influence and social selection are sub-components of a more general a co-evolutionary process linking network structure and individual behavior. …”

Smoking-based selection and influence in gender-segregated friendship networks: a social network analysis of adolescent smoking. by Mercken, L, Snijders, T, Steglich, C, Vertiainen, E, de Vries, H

“…MEASUREMENTS: Smoking behaviour of adolescents, parents, siblings and friendship ties. FINDINGS: Smoking-based selection of friends was found in male as well as female networks. …”
