Ethnic Diversity, Social Trust and the Moderating Role of Integration Policy

Increasing ethnic diversity and whether or not it impacts on trust are highly debated topics. Numerous studies report a negative relationship between diversity and trust, particularly in the US. A growing body of follow-up studies examined the extent to which these findings can be transferred to Europe, but the results remain inconclusive. Moving beyond the discussion of the mere existence or absence of diversity effects on trust, this study is concerned with the moderation of this relationship: It addresses the neglected role of subnational integration policies influencing diversity’s impact on trust. Empirical tests not only indicate that integration policies moderate the relationship, but also suggest that the influence of policies varies substantively according to the specific policy aspect under consideration.

The Personal Foundations of Political Tolerance towards Immigrants

In this paper, we expand previous research on the psychological foundations of attitudes towards immigrants by evaluating the role of the Big Five personality traits with regard to the formation of political tolerance. Following the literature, we elaborate tolerance as a sequential concept of rejection and acceptance to uncover differentiating effects of personality on both immigrant-specific prejudices as well as on the assignment of the right to vote as a pivotal political privilege to this group. Using a representative sample of the Swiss population, with its distinctive history related to the immigration issue, our two-step Heckman selection models reveal that extroverts and people who score low in agreeableness exhibit negative attitudes towards immigrants. At the same time, only openness to experience is significantly connected to the likeliness of granting immigrants the right to vote.

Ethnic disparity in defensive coping endothelial responses: The SABPA study

OBJECTIVES Defensive coping (DefS) in Blacks has been associated with greater cardiovascular risk than in their White counterparts. We examined associations between endothelial function mental stress responses and markers of vascular structure in a bi-ethnic cohort. METHODS We examined vascular function and structure in 368 Black (43.84±8.31years) and White Africans (44.78±10.90years). Fasting blood samples, 24h blood pressure, left carotid intima-media thickness of the far wall (L-CIMTf), and left carotid cross-sectional wall area (L-CSWA) values were obtained. von Willebrand factor (VWF), endothelin-1 (ET-1) and nitric oxide metabolite (NOx) responses to the Stroop mental stress test were calculated to assess endothelial function. DefS was assessed using the Coping Strategy Indicator questionnaire. Interaction between main effects was demonstrated for 283 participants with DefS scores above the mean of 26 for L-CIMTf. RESULTS Blunted stress responses for VWF (men 16.71% vs. 51.10%; women 0.85% vs. 42.09%, respectively) and NOx (men -64.52% vs. 74.89%; women -76.16% vs. 113.29%, respectively) were evident in the DefS Blacks compared to the DefS Whites (p<0.001). ET-1 increased more in Blacks (men 150% and women 227%, p<0.001) compared to the Whites (men 61.25% and women 35.49%, p<0.001). Ambulatory pulse pressure, but not endothelial function markers, contributed to L-CIMTf (ΔR(2)=0.11 p<0.001), and L-CSWA (ΔR(2)=0.08, p<0.001) in DefS African men but not in any other group. CONCLUSIONS Blunted stress-induced NOx and VWF responses and augmented ET-1 responses in DefS Blacks indicate endothelial dysfunction. DefS may facilitate disturbed endothelial responses and enforce vascular remodelling via compensatory increases in pulse pressure in Black men. These observations may indicate an increased risk of cardiovascular incidents via functional and structural changes of the vasculature in DefS Blacks.

Ethnic Politics, Regime Support and Conflict in Central and Eastern Europe

Ethnicity and ethnic parties have often been portrayed as a threat to political stability. There is also no shortage of conflicts with an ethnic flavor. Yet, this book challenges the notion that the organization of politics in heterogeneous societies should necessarily overcome ethnicity. Rather, descriptive representation of ethnic groups arguably has potential to increase regime support and reduce conflict. The book studies partisan-descriptive representation of up to 130 ethnic groups in central and eastern European democracies. Ethnic minority parties are found to only run and succeed if they can expect electoral support sufficient to pass the electoral threshold. Conditional on gender and strategies of representation, ethnic representation increases satisfaction with democracy among the minority population. While protest rises given moderate levels of representation, it is reduced once ethnic groups have access to executives. In conclusion, a proportional vision of power-sharing between ethnic groups receives some qualified empirical support.
