The Effects of Living in Segregated vs. Mixed Areas in Northern Ireland: A Simultaneous Analysis of Contact and Threat Effects in the Context of Micro-Level Neighbourhoods

This study examines the consequences of living in segregated and mixed neighbourhoods on ingroup bias and offensive action tendencies, taking into consideration the role of intergroup experiences and perceived threat. Using adult data from a cross-sectional survey in Belfast, Northern Ireland, we tested a model that examined the relationship between living in segregated (N = 396) and mixed (N = 562) neighbourhoods and positive contact, exposure to violence, perceived threat and outgroup orientations. Our results show that living in mixed neighbourhoods was associated with lower ingroup bias and reduced offensive action tendencies. These effects were partially mediated by positive contact. However, our analysis also shows that respondents living in mixed neighbourhoods report higher exposure to political violence and higher perceived threat to physical safety. These findings demonstrate the importance of examining both social experience and threat perceptions when testing the relationship between social environment and prejudice.

Multi-Contact Grasp Interaction for Virtual Environments

The grasping of virtual objects has been an active research field for several years. Solutions providing realistic grasping rely on special hardware or require time-consuming parameterizations. Therefore, we introduce a flexible grasping algorithm enabling grasping without computational complex physics. Objects can be grasped and manipulated with multiple fingers. In addition, multiple objects can be manipulated simultaneously with our approach. Through the usage of contact sensors the technique is easily configurable and versatile enough to be used in different scenarios.

Determinants of Experience of Discrimination in Minorities in Germany

This study examines perceived ethnic discrimination (as opposed to “objective” discrimination). It includes a discussion of definitions of discrimination and attempts to measure it, and a review of findings on the distribution of discrimination experiences among minorities. The aim of the study is to determine the influence of factors that increase the risk of exposure to situations in which discrimination can take place (exposure hypothesis), and those that sensitize perceptions and give rise to different frequencies of subjective feelings of discrimination (sensitization hypothesis). A standardized questionnaire was administered to a random sample of German-born persons of Turkish and Greek origin and Aussiedler (ethnic Germans born in the former Soviet Union) (total N = 301). Minorities of non-German, especially of Turkish origin reported significantly more discrimination than Aussiedler in a set of nineteen everyday situations. A bivariate correlation was found between number of incidents reported and employment status with homemakers reporting the fewest incidents. However, multiple regression analysis yielded no significant effect, thus lending no clear support to the exposure hypothesis. Frequency of contacts with German friends has no effect and seems not to entail an increase in exposure opportunities, but may lead to a desensitization to discrimination due to the erosion of the relevance of ethnic categories. On the other hand, an influence through intra-ethnic contacts clearly occurs, as frequency of contact with co-ethnic friends exerts a strong positive effect on experienced discrimination. A similar effect was found for ethnic self-awareness. The latter finding confirms the sensitization hypothesis.
