  • Opportunities and challenges of using targeted advertisements on social media to sample ethnoreligious minorities

    Open Access•L Leszczensky, David Kretschmer et al.•ARTICLE•International Journal of Social…•2026

    Targeted ads on social media allow researchers to recruit hard-to-reach or small populations such as ethnoreligious minorities. Seeking to guide researchers in dealing with the corresponding opportunities and challenges, we address three questions. First, how to define targeting criteria for ads aimed at recruiting ethnoreligious minorities on social media? Second, how costly is the recruitment of ethnoreligious minorities? Third, to what extent …

  • Mental wellbeing and ethnic brokerage in friendship networks of adolescents in German secondary schools

    Kathrin Lämmermann•ARTICLE•New Community•2025•Cited by: 1•References: 59

    Inter-ethnic brokerage between friends, i.e. having friends with different ethnic backgrounds who are not friends with each other, is essential to social integration processes in multi-ethnic societies. This study examines the relation between inter-ethnic brokerage in adolescent friendship networks and individual mental wellbeing in the school context. Using data on friendship networks from a large-scale study of more than 2,700 seventh-graders …

  • How gendered religious norms contribute to the emerging gender gap in Muslim youths’ interreligious friendships

    Open Access•D Kretschmer, Kathrin Lämmermann et al.•ARTICLE•International Journal of…•2024•Cited by: 5•References: 50

    Recent research finds that Muslim girls increasingly have in-group friendships in adolescence, while Muslim boys remain more open to interreligious friendships. This gender gap mirrors established findings of female Muslims’ lower involvement in interreligious romantic relationships, which is attributed to gendered religious norms. In this study, we examine whether gendered religious norms also contribute to the emerging gender gap in Muslim yout…

  • Who is fighting with whom? How ethnic origin shapes friendship, dislike, and physical violence relations in German secondary schools

    Open Access•M Wittek, Clemens Kroneberg et al.•ARTICLE•Social Networks•2020

    This study examines the role of ethnic background for friendship, dislike, and violence networks in secondary school. We analyze data on multiple networks from a large-scale study of more than 2500 seventh-graders in Germany. In addition to ethnic homophily in friendship networks, our results reveal a tendency among students to dislike ethnic outgroup members (ethnic heterophobia). However, students are more likely to engage in violence towards s…
