Promoting Positive Leadership: Examining the Long-Term Dynamics of Anti-Bullying Programs.

Anti-bullying programs can create more positive classroom environments by fostering the development of positive leaders who establish constructive norms. The social identity theory of leadership addresses stability and change within different leader profiles and identifies leader group prototypicality: the extent to which leaders are perceived to embody the group identity, including standards, values, and norms. This study focuses on two key areas: (1) examining stability and change within positive and negative leader profiles, and (2) comparing transition probabilities between the KiVa anti-bullying intervention condition and a control condition.

Neural correlates of vicarious reward processing and peer victimization experiences in late childhood.

This preregistered study examined the neural correlates of vicarious reward processing and subsequent trust behavior in relation to experiences of victimization averaged over two years in late childhood. This study used a sample of children with prospective longitudinal data on peer victimization over the past two years (n = 83, 49.4 % girls, M = 10.

Angry or neutral, it does not matter to me: Implicit processing of facial emotions is not related to peer victimization experiences.

The aim of this study was to examine whether prolonged victimization relates to differential processing of emotions. Based on the social information processing theory, it was hypothesized that prolonged victimization would modulate emotion processing, such that victimization relates to a heightened attentional focus toward negative facial expressions and increased amygdala activation in response to negative facial expressions. We targeted a unique sample of 83 children ( = 10.

MOLGENIS Armadillo: a lightweight server for federated analysis using DataSHIELD.

Summary: Extensive human health data from cohort studies, national registries, and biobanks can reveal lifecourse risk factors impacting health. Combining these sources offers increased statistical power, rare outcome detection, replication of findings, and extended study periods. Traditionally, this required data transfer to a central location or separate partner analyses with pooled summary statistics, posing ethical, legal, and time constraints.

The Dominance of Liking: Uncovering Dyadic and Reputational Effects of Peer and Perceived Teacher Likes and Dislikes on Friendship Dynamics Among Chinese Adolescents.

While previous research suggests that peer and teacher preferences are linked to adolescents' peer relationships, the specific impact of peer and teacher (dis)liking on adolescents' friendship networks is not fully understood. This study used longitudinal social network analysis to examine how peer (dis)liking and perceptions of teacher (dis)liking predicted friendship selection among Chinese adolescents. Questionnaires were administered to a sample of 2566 students (48.
