Explaining immigrants' social distance towards natives: A multilevel mediation approach across immigrant groups in Germany.

What factors underlie immigrants' social distance towards natives? Previous studies found that immigrants who perceive themselves as rejected by natives express more negative intergroup attitudes towards natives. Another line of research found that contingent on their origin country, immigrants face different degrees of social distance from natives. In this study, we employ an intergroup threat approach to integrate these separate research strands.

Observing many researchers using the same data and hypothesis reveals a hidden universe of uncertainty.

This study explores how researchers' analytical choices affect the reliability of scientific findings. Most discussions of reliability problems in science focus on systematic biases. We broaden the lens to emphasize the idiosyncrasy of conscious and unconscious decisions that researchers make during data analysis.

Explaining Immigrants' Worries About Ethnic Harassment: Germany, 1986-2004.

What factors shape immigrants' worries about becoming targets of ethnic harassment? This is an important question to ask, but most previous studies restricted their focus to the microlevel only. By contrast, few if any studies examined the possible macrolevel antecedents driving harassment-related worries among immigrants. This study aims to help fill this gap.

How education systems shape cross-national ethnic inequality in math competence scores: Moving beyond mean differences.

Here we examine a conceptualization of immigrant assimilation that is based on the more general notion that distributional differences erode across generations. We explore this idea by reinvestigating the efficiency-equality trade-off hypothesis, which posits that stratified education systems educate students more efficiently at the cost of increasing inequality in overall levels of competence. In the context of ethnic inequality in math achievement, this study explores the extent to which an education system's characteristics are associated with ethnic inequality in terms of both the group means and group variances in achievement.

The dynamics of radical right-wing populist party preferences and perceived group threat: A comparative panel analysis of three competing hypotheses in the Netherlands and Germany.

Existing cross-sectional research considers citizens' preferences for radical right-wing populist (RRP) parties to be centrally driven by their perception that immigrants threaten the well-being of the national ingroup. However, longitudinal evidence for this relationship is largely missing. To remedy this gap in the literature, we developed three competing hypotheses to investigate: (a) whether perceived group threat is temporally prior to RRP party preferences, (b) whether RRP party preferences are temporally prior to perceived group threat, or (c) whether the relation between perceived group threat and RRP party preferences is bidirectional.

Ethnic intermarriage in longitudinal perspective: testing structural and cultural explanations in the United States, 1880-2011.

Focusing on macro-level processes, this article combines Decennial Census and Current Population Survey data to simultaneously test longitudinal and cross-sectional effects on ethnic intermarriage using structural and cultural explanations. Covering a 130 year period, the results of our multilevel analysis for 140 national-origin groups indicate that structural characteristics explain why some origin groups become more "open" over time while others remain relatively "closed". Ethnic intermarriage is more likely to increase over time when the relative size of an immigrant group decreases, sex ratios grow more imbalanced, the origin group grows more diverse, the size of the third generation increases and social structural consolidation decreases.

Immigrant Integration policies and perceived Group Threat: A Multilevel Study of 27 Western and Eastern European Countries.

Although immigrant integration policies have long been hypothesized to be associated with majority members' anti-immigrant sentiments, systematic empirical research exploring this relationship is largely absent. To address this gap in the literature, the present research takes a cross-national perspective. Drawing from theory and research on group conflict and intergroup norms, we conduct two studies to examine whether preexisting integration policies that are more permissive promote or impede majority group members' subsequent negative attitudes regarding immigrants.
