Friendship Selection and Influence Processes for Physical Aggression and Prosociality:Differences between Single-Sex and Mixed-Sex Contexts

The present study examined to what extent selection and influence processes for physical aggression and prosociality in friendship networks differed between sex-specific contexts (i.e., all-male, all-female, and mixed-sex classrooms), while controlling for perceived popularity. Whereas selection processes reflect how behaviors shape friendships, influence processes reveal the reversed pattern by indicating how friends affect individual behaviors. Data were derived from a longitudinal sample of early adolescents from Chile. Four all-male classrooms (n = 150 male adolescents), four all-female classrooms (n = 190 female adolescents), and eight mixed-sex classrooms (n = 272 students) were followed one year from grades 5 to 6 (M age = 13). Analyses were conducted by means of stochastic-actor-based modeling as implemented in RSIENA. Although it was expected that selection and influence effects for physical aggression and prosociality would vary by context, these effects showed remarkably similar trends across all-male, all-female, and mixed-sex classrooms, with physical aggression reducing and with prosociality increasing the number of nominations received as best friend in all-male and particularly all-female classrooms. Further, perceived popularity increased the number of friendship nominations received in all contexts. Influence processes were only found for perceived popularity, but not for physical aggression and prosociality in any of the three contexts. Together, these findings highlight the importance of both behaviors for friendship selection independent of sex-specific contexts, attenuating the implications of these gendered behaviors for peer relations

Bullying as a Group Process in Childhood:A Longitudinal Social Network Analysis

This study investigates the dynamic interplay between bullying relationships and friendships in a sample of 481 students in 19 elementary school classrooms (age 8-12 years; 50% boys). Based on a relational framework, it is to be expected that friendships would be formed when two children bullied the same person and that children would start to bully the victims of their friends. Similarly, it is to be expected that friendships would be formed when two children were victimized by the same bully and that children would become victimized by the bullies of their friends. Longitudinal bivariate social network analysis supported the first two hypotheses but not the latter two. This study provides evidence for group processes in bullying networks in childhood

Structure, Multiplexity, and Centrality in a Corruption Network:The Czech Rath Affair

The present study is an analysis of a Czech political corruption network known as the Rath affair reconstructed with publicly available data. We argue that for the study of criminal networks it is fruitful to follow a multiplex approach, i.e., to distinguish several interdependent network dimensions and study how they are interrelated. Relational elements in corruption are identified, and we propose three dimensions that are essential for understanding the Rath network: pre-existing ties (e.g., marriage or co-membership of the same party), resource transfer (e.g., bribing), and collaboration (e.g., communication). The aim of the study was threefold. We aimed to examine if the network exhibits the core/periphery structure, to investigate the multiplex structure of the network by assessing the overlap of the main dimensions of the network, and to determine the central and multiplex actors while considering the differentiation of centrality according to the three network dimensions. The core/periphery model appears to have a perfect fit to the aggregated network, leading to a four-block adjacency matrix. Studying the frequency of ties in these blocks shows that collaboration ties are present in all the blocks, while resource transfer ties are mainly located between the core and periphery, and pre-existing ties are rare generally. We also identify central actors, none of which are strategically positioned, occupying more visible positions instead. The majority of actors display strong multiplexity in the composition of their own ties. In the conclusion the potential usefulness of multiplex descriptive measures and of mixed methods approaches, implications of our results for trust incriminal networks, and potential merits of analytical sociology approach are discussed

The Complex Relation Between Bullying, Victimization, Acceptance, and Rejection:Giving Special Attention to Status, Affection, and Sex Differences

To understand the complex nature of bullies' acceptance and rejection, this article considered goal-framing effects of status and affection as they relate to the gender of the bully (male vs. female bullies), the target (male vs. female victims), and the evaluator (acceptance and rejection from male vs. female classmates). The hypotheses were tested with data from a social network questionnaire conducted in 26 elementary school classes (N = 481 children; M(age) = 10.5 years). The findings revealed that bullies were only rejected by those for whom they were a potential threat and that bullies generally chose their victims so as to minimize loss of affection by choosing victims who were not likely to be defended by significant others

Poisonous connections:a case study on a Czech counterfeit alcohol distribution network

Using data on 32 actors and ties among them drawn from available court files, we combine analytical sociology with statistical models for networks in order to analyse a case of a counterfeit alcohol distribution network from the Czech Republic. We formulate a theory of action and identify relational mechanisms which could explain how the structure of the network emerged and describe. We use the exponential random graph model to test these mechanisms. The analysis reveals that the two actors capable of manufacturing the poisonous mixture were considerably though not optimally proximate to others enabling fast distribution of the mixture. Our model results that the structure was formed by mechanisms of triadic closure, negative tendency to concentrate ties, and tie translation of pre-existing ties into operational ties. We conclude with the discussion of the implications our approach for the study of criminal networks

Sexual identity disparities in mental health among U.K. adults, U.S. adults, and U.S. adolescents:Examining heterogeneity by race/ethnicity

Lesbian, gay, and bisexual (LGB) people report poorer mental health than heterosexual people. However, there is heterogeneity in this disparity, and a racial/ethnic minority identity can contribute to this heterogeneity. When studying the intersecting effect of sexual identity and race/ethnicity on mental health, research often limits race/ethnicity categories, often uses adult samples from the U.S., and often uses samples that are not nationally representative. To overcome these limitations, the present study examined racial/ethnic heterogeneity in mental health disparities between heterosexual and LGB people in three nationally representative samples. The samples used were the 2011–2012 Understanding Society (U.K. adults; N = 43,904), the 2015 National Survey on Drug Use and Health (U.S. adults; N = 43,313), and the 2015 Youth Risk Behavior Survey (U.S. adolescents; N = 15,122). Using these samples enabled us to contrast the intersection of sexual identity and race/ethnicity across countries (for adults), and between life phases (in the U.S.). Across all three samples, LGB people—and particularly bisexual people—had a higher risk of impaired mental health than heterosexual people. For U.K. adults and U.S. adults, no intersecting effect of sexual identity and race/ethnicity were found. LGB adolescents of color reported better mental health compared with White LGB adolescents. More specifically, Black LGB adolescents reported better mental health compared to White LGB adolescents. Together, the present study contributes to a better understanding of the heterogeneity in mental health disparities for LGB people

Status inconsistency in groups:How discrepancies between instrumental and expressive status result in symptoms of stress

This study examines whether a mismatch between the positions that individuals hold in different status hierarchies results in symptoms of stress. Prior research has focused on inconsistencies between socioeconomic status dimensions (e.g., education and income) and did not find a significant relation between status inconsistency and stress. In this paper, we build on research on role differentiation and propose to study the effect of inconsistencies between instrumental status and expressive status in group contexts. We hypothesize that people with an inconsistency between these status dimensions experience feelings of uncertainty and frustration in their interactions with others and this manifests in stress-related symptoms. We test this hypothesis with data collected in a medium-sized Dutch childcare organization (N = 93). Polynomial regression analysis, visualized in response surface plots, suggests that status inconsistent employees report higher levels of stress

Friendships, perceived popularity, and adolescent romantic relationship debut

This study examined the association of friendships and popularity with adolescents’ first-time involvement in a romantic relationship (referred to as romantic relationship debut). The aim of this article was twofold: first, to disentangle the unique effects of friendships and perceived popularity; second, to separate same- and cross-gender peer nominations. Specifically, it was tested whether same- and cross-gender friendships or same- and cross-gender popularity were more likely to increase the likelihood of romantic relationship debut. Using longitudinal data of 590 Dutch adolescents age 12 to 18 (57 % girls) from TRAILS (Tracking Adolescents’ Individual Lives Survey), results are consistent with the hypothesis that cross-gender friendships and cross-gender popularity increase the chances of a romantic relationship debut. Findings indicate that peer evaluations by cross-gender peers of both friendships and popularity account for adolescents’ romantic relationship debut

Disentangling dyadic and reputational perceptions of prosociality, aggression, and popularity in explaining friendship networks in early adolescence

This study examined the differential effects of two forms of adolescents' perceptions of peers' prosociality, aggression, and popularity, on friendship selection. Individuals' reports of their peers' behaviors (dyadic perceptions) and the aggregated classmates' reports (reputational perceptions) were disentangled. The findings indicated that adolescents were more likely to befriend classmates widely perceived as prosocial (reputational perception) and were less likely to befriend classmates they perceived as aggressive (dyadic perception). For popularity, the effect of dyadic perception disappeared when including the reputational perception. The findings highlight the differences between the dyadic and reputational perceptions of peer behavior. Not only dyadic perceptions of behaviors but also reputational perceptions exert a role in befriending peers
