Needed but Not Liked – The Impact of Labor Market Policies on Natives’ Opinions about Immigrants

This article builds on the notion that immigrants’ integration into the labor market benefits migrants and shapes natives’ opinions about immigrants. Using insights from the newest literature on labor immigration and drawing upon the literature on attitudes toward immigrants, the article explores in a multilevel design the impact that regulations in the EU member states concerning immigrants’ access to domestic labor markets have on threat perceptions and on opinions about immigrants’ economic role. It finds that labor market regulations have a positive effect on opinions about immigrants’ economic role and reduce the negative relationships between precarious labor market status and opinions about the economic role. However, a robust effect of labor market regulations on threat perceptions was not found. Our results imply that labor market incorporation rules need to be accompanied by other measures to close the gap between natives and immigrants.     

Disentangling Gut Feeling: Assessing the Integrity of Social Entrepreneurs

This paper analyzes how social venture capitalists evaluate the integrity of social entrepreneurs. Based on an experiment with 40 social venture capitalists and 40 students, we investigate how five attributes of the entrepreneur contribute to the assessment of integrity. These attributes are the entrepreneur’s personal experience, professional background, voluntary accountability efforts, reputation and awards/fellowships granted to the entrepreneur. Results indicate that social venture capitalists focus largely on voluntary accountability efforts of the entrepreneur and the entrepreneur’s reputation when judging integrity. For an overall positive judgment of integrity, it seems to be sufficient if either voluntary accountability efforts or reputation of the entrepreneur are high. By comparing social venture capitalists with students, we show that experience leads to a simpler decision model focusing on key attributes.

Institutioneller Wettbewerb und Karrierechancen von Nachwuchswissenschaftlern in der Chemie

This paper examines the interplay between intensifying competition among scientific institutions, on the one hand, and career opportunities of young scientist, on the other hand, using chemistry-departments in German universities and non-academic research institutes as an example. Drawing on Bourdieu, we construct and analyze the filed in which institutional competition takes place. The power relations in the field are structured by the relative amount of “pure scientific capital” and/or “institutional capital” available. In an analysis of professorial appointments we show that the field’s structure has little impact on junior scientsits’ career opportunities. In contrast to the US, where pervasive institutional competition goes hand in hand with a high degree of social closure in academic careers, we find that career opportunities are (still) relatively open in the German case, in spite of growing competition. This openness is due to the special institutional framework that provides the German academic field with a relatively high degree of autonomy. As recent changes in science policy aim to alter the institutional framework, they also jeopardize the autonomy of the academic field.     

Religiös-konfessionelle Kultur und individuelle Religiosität: Ein Vergleich zwischen West- und Ostdeutschland

In religious terms, East and West Germany are still two separate societies more than 20 years after reunification. While the large majority of the population in West Germany belongs to one of the two main Christian churches, the proportion of those without a denomination in East Germany is now more than 70 %. Moreover, as far as church involvement, confidence in the church and individual religiosity are concerned, the West Germans have a much stronger religious affiliation to the church than their East German counterparts. The main reason for this difference is the influence of different political systems and legal cultures in East and West during the period when the two parts of Germany were divided. The fact, though, that the process of secularization has continued unabated in East Germany since 1989, and that the religious and ecclesiastical discrepancies between the two parts of the country have, if anything, become stronger rather than weaker since then, would suggest that there are other factors at work here, too. In this contribution, we argue that one of the factors that needs to be considered is the dominant denominational culture that exists in each of the two parts of the country, a culture which is highly persistent, can easily reproduce itself, puts pressure on the respective minority cultures, and is able to diffuse into them. While the dominant denominational culture in West Germany is able to slow down the current processes of secularization, the secular, non-denominational majority culture in the East tends rather to produce effects which accelerate these processes. In this essay, we use a variety of empirical indicators (effectiveness of religious socialization, denominational affiliation, churchly affiliation, faith in God) to demonstrate these effects.     

Political parties' perceptions and uses of anti‐Semitic conspiracy theories in Turkey

Despite its ever‐present and at times escalating significance, conspiracy theory is an under‐researched topic in the social sciences. This paper analyses the political influence of conspiracy theories by drawing on semi‐structured interviews with the representatives of four major political parties from the Turkish parliament about widespread anti‐Semitic conspiracy theories regarding Dönmes (converts). The findings indicate that right‐wing political parties problematize the secret character of the Dönme community and use the conspiracy theories to express their own ontological insecurities emerging from the Sèvres syndrome. Left‐wing and liberal parties conversely dissociate themselves from the conspiratorial rhetoric. The research concludes that the political parties reject or accept the conspiracy theories rationally and in alignment with their own ontological insecurities; by doing so, they pragmatically confirm their individual ideological perspective.     

Difficulties in Diagnosing Sexual Abuse in Children with Condyloma Acuminata in Turkey

Human papillomavirus is responsible for anogenital warts and could be regarded as an indicator of possible sexual abuse in children. A genital wart was detected during an investigation of anti–hepatitis C virus positivity in a four-year-old male patient. No pathological findings of another sexually transmitted disease were found except complete cleft palate and circumferential lesions in the perianal region. No family member was anti-hepatitis C virus positive, but the patient's uncle and his wife had genital condylomata. Although detailed physical examination uncovered no other findings indicative of sexual abuse, suspicion of abuse could not be eliminated. Therefore, we wanted to draw the attention of health professionals to the association of anogenital warts and sexual abuse.     

Far Away So Close: Race,Whiteness, and German Identity

Race and nation have been difficult concepts in Germany since the Holocaust. Although race has seemingly disappeared from public discourse, the concept is very present in the narrative construction of white German national identities. In fact in Germany, race, and more specifically whiteness, disappears into a national naming. On the basis of a qualitative study on women activists, I examine to what extent the research participants struggle with the racialized discourse on German identity and what this struggle looks like. Using John Hartigan's (2000 Hartigan, John Jr. 2000. Object lessons in whiteness: Antiracism and the study of white folks. Identities: Global Studies in Culture and Power, 7(3): 373–406. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) approach to analyzing ethnographic accounts of whiteness, I show how a racialization of German identity plays out in complex and complicated ways. On the one hand, the narratives are complicit with a racialized Germanness, yet on the other hand, the idea of a unified, white, cultural community is being challenged. To move toward a postcolonial narrative of Germanness that includes Germany's history of colonialism as well as fascism, we need to move away from race, but we also need to move toward race. A starting point would be provided by focusing on racism, not as a fringe issue of German society but rather as an urgent matter that is located at the centre of German politics and is actively shaping its history.
