Rethinking Timing of First Sex and Delinquency   总被引:1,自引:1,他引:0  
The relation between timing of first sex and later delinquency was examined using a genetically informed sample of 534 same-sex twin pairs from the National Longitudinal Study of Adolescent Health, who were assessed at three time points over a 7-year interval. Genetic and environmental differences between families were found to account for the association between earlier age at first sex and increases in delinquency. After controlling for these genetic and environmental confounds using a quasi-experimental design, earlier age at first sex predicted lower levels of delinquency in early adulthood. The current study is contrasted with previous research with non-genetically informative samples, including Armour and Haynie (2007, Journal of Youth and Adolescence, 36, 141–152). Results suggest a more nuanced perspective on the meaning and consequences of adolescent sexuality than is commonly put forth in the literature.

The present study examines how exposure to relational aggression at school is associated with adolescents’ perceptions of, and participation in, a hostile school environment. Participants were 1,335 African American and European American adolescents in grades 7 through 12 (52% female, 49% African American). Results indicate that exposure to relational aggression is associated with several components of adolescents’ perceptions of the school climate. Adolescents exposed to high levels of relational aggression perceived their school to be less safe, and were less pleased with the general social atmosphere at school. Moreover, for males, but not females, exposure to relational aggression was associated with carrying a weapon to school. Implications and suggestions for future research are discussed in terms of working toward safer school environments for adolescents.

Cosmopolitan democracy is one of the most debated models of transnational democracy. As a result of his prominence in this field, David Held has attracted much of the criticism and approval of this position. The critique and comment aimed at cosmopolitanism in general, and Held's work in particular, has provoked cosmopolitan advocates to respond, restate and develop their arguments. However, despite its considerable merit, this debate remains largely theoretical, and little has been done in terms of studying the realisation of cosmopolitanism in real-world settings. This article contributes towards the debate concerning the possibility of its actual application by mapping the principles of cosmopolitan democracy in relation to the EU polity and the issue of gender equality. It argues that the EU articulates certain cosmopolitan-comparable principles, and by studying areas where they are clearly exhibited, such as the issue of gender, that this helps us to critically evaluate their practicability and enables a response to criticisms levelled at cosmopolitan democracy. This article addresses two specific criticisms. Firstly, in view of the justiciable qualities of EU law, and its ability to give rise to formal individual rights, it is argued that claims regarding the inherently fictitious nature of cosmopolitan rights are unfounded. Secondly, while acknowledging that civic engagement takes a principally legal mode in relation to the issue of gender, this article rejects the claim that cosmopolitan democracy neglects the political aspects of citizenship. However, cosmopolitan scholars must extend their understanding of the relation between rights and the wider aspects of citizenship engagement, if they hope to realise the vision of an active citizenry that remains central to the cosmopolitan project.  相似文献

Surprise party     
Alesina’s (Quarterly Journal of Economics 102, 651–678, 1987) influential model of presidential elections with ideologically motivated parties attributes higher growth and lower unemployment under Democratic presidents to the surprise inflation a Democratic victory entails. In contrast to the published literature, we test this hypothesis using calculations of presidential election surprises consistent with the assumption of rational economic actors. We confront the econometric complications attending a time-series approach taking into account economic growth dynamics. We ultimately fail to confirm the hypothesis that the level of uncertainty associated with presidential election results has an effect on economic outcomes.  相似文献

As the Soviet Union disintegrated and eventually dissolved in 1991, many of its peoples, both so-called titular nationalities and national minorities, put forth demands for independence or, at the very least, self-rule for territories that were said to represent the national patrimony. Among the many peoples who put forward such demands were Carpatho-Rusyns, who, together with fellow citizens of other national backgrounds, demanded autonomy or self-rule for the region (oblast) of Transcarpathia in far western Ukraine. This essay examines from a historical perspective the question of autonomy or self-rule for Carpatho-Rusyns and for all or part of the territory they inhabit, historic Carpathian Rus’. The autonomy question in Carpathian Rus’ is hardly new, but one that goes as far back as 1848.  相似文献
