Utilizing a risk and protective factors approach, this research examined the relationship between self-reported depressive
symptomatology, group membership (bully, victim, bully–victim) risks, and protection among a sample of African–American youths.
Self-report data were collected in spring, 2002. Youth in grades 5–12 were sampled (n = 1,542; 51% female) from an urban school district in the Southeast. African–American youths self-identifying as bullies,
victims, or bully–victims, reported higher levels of depressive symptoms compared to their nonbullied–nonvictimized counterparts.
Additionally, multivariate results highlight a significant set of risk and protective factors associated with depressive symptomatology,
even after controlling for the effects of self-identified group membership. These findings further contribute to our general
understanding of the interplay among bullying, victimization, risk and protective factors, and their effects on depressive
symptoms among a group of understudied African–American youth. 相似文献

This article aims to make a contribution to debates about how to conceptualise normativity. It argues that normativity can not be just understood through defining it and in particular through identifying conceptual boundaries around the normative and the non-normative. Instead the article suggests that it is important to explore how transitions between the non-normative and the normative occur in practice. This argument is developed through a critical examination of literature on legal pluralism and an analysis of qualitative empirical data on the drafting of technical guidance documents under the European Union Directive on Integrated Pollution Prevention and Control (96/61/EC). 相似文献

In forensic science, there is a strong interest in determining the post-mortem interval (PMI) of human skeletal remains up to 50 years after death. Currently, there are no reliable methods to resolve PMI, the determination of which relies almost exclusively on the experience of the investigating expert. Here we measured (90)Sr and (210)Pb ((210)Po) incorporated into bones through a biogenic process as indicators of the time elapsed since death. We hypothesised that the activity of radionuclides incorporated into trabecular bone will more accurately match the activity in the environment and the food chain at the time of death than the activity in cortical bone because of a higher remodelling rate. We found that determining (90)Sr can yield reliable PMI estimates as long as a calibration curve exists for (90)Sr covering the studied area and the last 50 years. We also found that adding the activity of (210)Po, a proxy for naturally occurring (210)Pb incorporated through ingestion, to the (90)Sr dating increases the reliability of the PMI value. Our results also show that trabecular bone is subject to both (90)Sr and (210)Po diagenesis. Accordingly, we used a solubility profile method to determine the biogenic radionuclide only, and we are proposing a new method of bone decontamination to be used prior to (90)Sr and (210)Pb dating. 相似文献

Developments in the information society in Russia have led to the creation of an abundance of online primary texts by political actors and institutions. This article surveys a large selection of official electronic texts with the aim of encouraging more extensive use of online sources and easing researchers' navigation of Russian politicians' use of the internet. While the authors do not claim that online data can replace the insights gained from elite interviews, the article suggests that online texts could be used more extensively as a valuable addition to existing methods applied to the study of Russian political elites. 相似文献

Mitochondrial DNA sequences of the entire control region were analyzed in 200 unrelated individuals from Macedonia. A total of 163 different haplotypes were found as determined by 177 polymorphic sites. The probability of a random match was calculated as 1:121 (0.83%). The basic phylogenetic structure of the Macedonian population as derived from its haplogroup distribution is in agreement with other West-Eurasian populations. Upon publication, the population data are going to be available in the EMPOP database (www.empop.org) [W. Parson, A. Dür, EMPOP—a forensic mtDNA database, FSI:Genetics 1 (2) (2007) 88–92; W.

The article analyses Germans' views of democracy in a longitudinal perspective, especially since unification. It is shown that most Germans in both parts of the country strongly support the idea of democracy although many are at the same time dissatisfied with its practice. This dissatisfaction rests on different motives, ranging from high normative democratic ideals over differences between the normative concept of democracy and the implemented one, including misconceptions of what democracy should or can be to anti-democratic attitudes. At present, Germany faces all these motives of dissatisfaction with democracy, yet in different strata and parts of the society. On the one hand, support for democracy suffers somewhat from declining interest in politics in general, which makes citizens unrealistic about political possibilities and their limits. On the other hand, feelings of economic deprivation, especially in the eastern part, still motivate sceptical views on the western kind of democracy and even in smaller parts of the public an alienation from the democratic credo. Growing inequalities throughout the whole of Germany, especially growing poverty in the lowest social strata, will cause additional systems stress, if it is not moderated by the social welfare system. Thus, the country needs more education in democratic politics for the citizens and more responsive politics on the side of the politicians including more open political structures for citizens' demands and participation. 相似文献
