Possible applications of Y chromosome STRs in examination of abortion tissue

By application of Y-chromosomal STRs, DNA analysis of abortion material can be considerably facilitated since great excess of maternal DNA is tolerated without disturbing the Y-STR amplification. If paternity can't be excluded on the basis of the Y-STR haplotype, further examinations must follow, e.g. autosomal STR analysis. For this purpose, histological preparation of the abortion tissue might still be necessary. Different Y-chromosomal haplotypes of embryo and putative father usually lead to an exclusion from paternity. Based on four case examples, the feasibility of this method is discussed.     

The Political Economy of Fiscal Policy: An Experimental Study on the Strategic Use of Deficits

Field data on the strategic use of deficits to limit thebudgetary scope of future governments are inconclusive aboutthe effects of political polarization or a government'sre-election probability on fiscal policy. Therefore, wedesigned a controlled experiment to examine the strategic useof deficits. Using a within-subjects design, we find thatdeficits rise with a higher degree of polarization and a lowerreelection probability. However, in a between-subjects designneither polarization nor reelection probabilities have asystematic effect. We discuss the implications of ourexperimental results for empirical tests of the strategic useof deficits with field data.     

Politics of Disclosure: Organizational Transparency as Multiactor Negotiation

Transparency is in vogue, yet it is often used as an umbrella concept for a wide array of phenomena. More focused concepts are needed to understand the form and function of different phenomena of visibility. In this article, the authors define organizational transparency as systematic disclosure programs that meet the information needs of other actors. Organizational transparency, they argue, is best studied as an interorganizational negotiation process on the field level. To evaluate its merit, the authors apply this framework to a case study on the introduction of open data in the Berlin city administration. Analyzing the politics of disclosure, they consider the similarities and differences between phenomena of visibility (e.g., open data, freedom of information), explore the transformative power of negotiating transparency, and deduce recommendations for managing transparency.     

The effects of tone,focus, and incivility in election debates

Previous research has found mixed evidence for the effectiveness of negative campaigning. Therefore, scholars have recently turned their attention to the question whether there are different dimensions of negativity. The present study contributes both empirically and methodologically to this debate by investigating the effects of three German chancellor debates using real-time response measurements of audience reactions. Following Brooks and Geer (2007. “Beyond Negativity: The Effects of Incivility on the Electorate.” American Journal of Political Science 51 (1): 1–16. doi:10.1111/j.1540-5907.2007.00233.x), we distinguish between debate statements along three different dimensions: negative versus positive tone, policy- versus person-focus, and civility versus incivility. Also, we demonstrate how debate content and real-time response measurements of audience reactions can be analysed using econometric time-series techniques. Our analyses show that civil policy-focused statements have a positive impact, as expected, while person-focused or uncivil statements rarely have positive effects. In the concluding section, the implications of our findings are discussed and directions for further research identified.     

Gender trouble on the German soccer field: can the growth of women’s soccer challenge hegemonic masculinity?

Soccer in Germany represents a social sphere for the expression of masculinity and features significant ideological battles over gender roles. This paper discusses whether the growth of women’s soccer can challenge the prevailing hegemonic masculinity in an area that represents an important economic aspect of consumer culture and social identity. Does women’s soccer have the potential to subvert existing gender norms and challenge dominant understandings of gender? While women’s soccer has seen some important areas of growth in Germany, there are reasons to remain sceptical about the subversive potential of women’s soccer. This article argues that the unholy trinity of the sports-media-business alliance is the root cause for the limitations women’s soccer faces in challenging hegemonic masculinity. This sports-media-business alliance has served as the structural framework that has shaped societal discourses about women’s soccer in Germany. This paper discusses three of those discourses: the evolution of the macro-historical discourse over the societal role of women’s soccer in post-World War II Germany; the discourse comparing men’s and women’s soccer and asserting the superiority of men’s soccer; and the discourse on the role of femininity in women’s soccer and the sexualization of the players.     

Flexible Integration,EMU and Relative Voting Power in the EU

This paper studies the implications offlexible integration in the European Union. Itanalyses the voting power of member states in theCouncil of Ministers when differently sized subgroupsof the EU are set up. European Monetary Union isreferred to as the most important example of flexibleintegration. The Banzhaf-Index is calculated to studythe distribution of voting power in the decisionmaking process according to the stability and growthpact. The results show considerable fluctuations,especially for smaller countries, in relative votingpower, the latter being defined as the relationbetween voting power and relative voting weight.     

Gelungene Integration in den Arbeitsmarkt?

This article discusses the social-structural dynamics of the biographies of transnationally mobile Europeans on the basis of 27 interviews, conducted in 2002–2003, with people of Italian, French, British, Danish, and Polish origin living in Berlin. In comparing different forms of mobility and taking into particular consideration the vocational aspects of the Europeans interviewed, this study reveals several characteristic types of transnational mobility within Europe. It does not only reveal the biographies of the elite or lower class Europeans, as these types have already been derived from the new transnational or classical migration research; it also unravels the biographies of a variety of transnational middle class Europeans. Furthermore, our study shows, that the availability of cultural and social capital is the determining factor for integration. These findings are an interesting extension to the sociological understanding of migration in the 21st century.     

Migration past and present: changing patterns in Kyrgyzstan

Internal and international labour migration is a main livelihood strategy for many people in rural areas of Kyrgyzstan. It is estimated that approximately one-third of the employable population of Kyrgyzstan is working abroad. However, current labour migration phenomena are not exceptional since Central Asia's history has always been characterized by the movement of people, including external and internal, forced and voluntary, legal and illegal, permanent and temporary, ethnically or economically motivated migration. This article gives an overview of the historical and present migration processes with a special focus on three village communities in rural Kyrgyzstan. It deals with the opportunities and difficulties with which labour migrants and their non-migrating family members are confronted today. The results are based on extensive field work in Kyrgyzstan.     

Experimental tests for the validation of active numerical human models

The development of numerical human models is a topic of current interdisciplinary research. In the field of automotive safety these models can be applied for the optimization of protection systems. In forensic research human models can be used for the investigation of injury mechanisms and for the prediction and reproduction of injury patterns. However, up to now human models have been validated on the basis of PMHS tests without considering the effects of muscle activity. This paper shows two experimental volunteer test set-ups for the generation of experimental validation data. In a pendulum set-up the influence of muscle activity on the human kinematics was investigated. A drop test set-up was developed for the analysis of the effects of muscle activity on impact response characteristics of muscle tissue. Experimental results, presented in this paper, can be used for the validation and optimization of active numerical human models.
