Maaike van der Vleuten (ICS-UU, yeargroup 2013) will defend her dissertation on Friday 19 January 2018 at 04:15 PM in the Utrecht University Hall. The title of her dissertation is: Gendered Choices. Fields of study of adolescents in the Netherlands.
This dissertation provides insight in the different ways in which adolescents’ social environment affects field of study choices, with a specific focus on how it leads boys and girls to different fields of study. It looks at the role of internalized gender ideologies as well as the influence of parents, siblings, and friends. Gender role socialization and resource theory are used to explain the influence of adolescents’ social environment. In line with gender role socialization theory, adolescents’ internalized gender ideology, friends and mothers lead to gender differences in fields of study. In line with resource theory, siblings and fathers influence field of study choices, but not in a way that contributes to gender inequality in educational fields. This dissertation shows that normative ideas of what is “appropriate” male or female behavior are influential for both boys’ and girls’ educational choices, but that the consequences of these norms appear more severe for girls than for boys. Suggestions are formulated to tackle the persuasiveness of these gender norms in order to reduce gender differences in fields of study.
Joran Laméris will defend her PhD thesis on Friday, January 19th 2018. The defense will take place at Radboud University, Aula (Comeniuslaan 4), 16:30h.
Against the background of a heated political debate about the possible threats of ethnic diversity for the well-being of society, this thesis improves the understanding of whether, why and where ethnic diversity erodes social cohesion. The findings indicate that steady increases in diversity do not challenge cohesion, whereas abrupt increases in diversity do – in any case temporarily – inhibit cohesion. Even though the negative diversity-cohesion relationship is hardly explained by ethnic threat and anomie, the results show that threat and anomie are important inhibitors for cohesion. As individuals’ perceptions of neighbourhood diversity and safety do explain the diversity-cohesion relationship, this study suggests that it especially matters what ethnic diversity represents in a given residential environment. Furthermore, the findings of this study reveal that the negative relationship between diversity and cohesion is strongest within small-scale residential environments. As people identify more strongly with the small-scale residential context, they are more affected by its ethnic composition.
Manja Coopmans (ICS-UU, year group 2013) will defend her dissertation on Friday 16 March at 12:45 PM in the Utrecht University Hall. The title of her dissertation is: Rituals of the past in the context of the present. The role of Remembrance Day and Liberation Day in Dutch society
The symposium will take place in the Academy building in Utrecht, in the “Belle van Zuylenzaal” and is titled:
Is that true? Replication and Meta-analysis in the social sciences
Science has currently been confronted with a so-called ‘replication crisis’, meaning that scientists have found that the results of many scientific studies cannot be replicated upon subsequent investigation. This crisis not only concerns the social sciences, but many other disciplines such as economics, biology, and medicine. It raises fundamental issues on the importance of replications, the generalizability of findings and theories, study design, the use of statistics to combine and interpret results, and the publication culture of empirical findings.
Five speakers address these fundamental issues raised by the replication crisis. Daniel Lakens of Eindhoven University of Technology and member of the programme committee of the NWO Grant Replication Studies, will address the importance of replications and the difficulty of combining and interpreting findings of original and replication studies. Jelte Wicherts of the meta-research center at Tilburg University will discuss how significant and non-significant replication findings should affect our belief that a hypothesis is true, and how these findings actually affect researchers’ beliefs of this hypothesis being true. Eric-Jan Wagenmakers of the University of Amsterdam and founder and director of the free statistical software JASP will tell about his experiences with pre-registered replication studies and how to interpret their findings. Fred Hasselman of Radboud University Nijmegen and co-author of several papers on ManyLab projects will discuss the implications of these projects for the generalizability of findings and the heterogeneity or contextual dependence of effects. Marcel van Assen of Utrecht University and the meta-research center at Tilburg University will demonstrate that the optimal design of replication studies, but of original studies as well, includes heterogeneous contexts rather than a few experimentally controlled conditions.
The program starts at 13:00 (Belle van Zuylenzaal Utrecht) and ends with drinks at 17:00. Please register via Saskia Simon (email@example.com).
