Developmentally salient research on perceived peer discrimination among minority youths is limited. Little is known about trajectories of perceived peer discrimination across the developmental period ranging from middle childhood to adolescence. Ethically concentrated neighborhoods are hypothesized to protect minority youths from discrimination, but strong empirical tests are lacking. The first aim of the current study was to estimate trajectories of perceived peer discrimination from middle childhood to adolescence, as youths transitioned from elementary to middle and to high school. The second aim was to examine the relationship between neighborhood ethnic concentration and perceived peer discrimination over time. Using a diverse sample of 749 Mexican origin youths (48.9 % female), a series of growth models revealed that youths born in Mexico, relative to those born in the U.S., perceived higher discrimination in the 5th grade and decreases across time. Youths who had higher averages on neighborhood ethnic concentration (across the developmental period) experienced decreases in perceived peer discrimination over time; those that had lower average neighborhood ethnic concentration levels showed evidence of increasing trajectories. Further, when individuals experienced increases in their own neighborhood ethnic concentration levels (relative to their own cross-time averages), they reported lower levels of perceived peer discrimination. Neighborhood ethnic concentration findings were not explained by the concurrent changes youths were experiencing in school ethnic concentrations. The results support a culturally-informed developmental view of perceived peer discrimination that recognizes variability in co-ethnic neighborhood contexts. The results advance a view of ethnic enclaves as protective from mainstream threats. 相似文献

Using data from a Canadian national representative sample survey of male university and college students, this study tested three hypotheses from a theoretical model which attempts to explain the relationship between male peer group dynamics and sexual assault in dating relationships. Consistent with previous research conducted in the United States, the findings reported here show that male peer support is a significant predictor of sexual abuse in post-secondary school courtship. This article concludes with several suggestions for further research. 相似文献

With reference to South Asia, we argue that recourse to the conventional structuralist and transition accounts of democratisation sustains an unhelpful dichotomy. Those approaches tend towards either determinism or agent-driven contingency. In contrast, an alternative approach that recognises the relevance of both structure and agency is proposed. In certain circumstances, human agency opens up the possibility of the relatively rapid transformation of structures. In particular, there are periods of political openness when structures are malleable, and individuals, or individuals acting collectively, are able to reshape structures. Decolonisation both constituted a moment of transition and opened up the possibility of structural change in the context of enhanced elite agency. For the purposes of comparison, the discussion covers the three cases of India, Pakistan and Sri Lanka. Particular attention is drawn to political parties and the structure of ethnic diversity as leading explanatory variables. 相似文献

Entire mitochondrial control region sequences were generated from 377 unrelated individuals from urban Hong Kong. In line with other control region datasets from China, the sample from Hong Kong exhibited significant genetic diversity that was reflected in a random match probability of 0.19% and a mean pairwise difference of 13.14. A total of 305 haplotypes were identified, of which 262 were unique. These sequences will be made publicly available to serve as forensic mtDNA reference data for China. 相似文献

This article examines the effects of hate speech laws in Australia. Triangulating data from primary and secondary sources, we examine five hypothesized effects: whether the laws provide a remedy to targets of hate speech, encourage more respectful speech, have an educative or symbolic effect, have a chilling effect, or create “martyrs.” We find the laws provide a limited remedy in the complaints mechanisms, provide a framework for direct community advocacy, and that knowledge of the laws exists in public discourse. However, the complaints mechanism imposes a significant enforcement burden on targeted communities, who still regularly experience hate speech. We find a reduction in the expression of prejudice in mediated outlets, but not on the street. We find no evidence of a chilling effect and we find the risk of free speech martyrs to be marginal. We draw out the implications of these findings for other countries. 相似文献

ABSTRACTThe delivery of public services by a mix of government and non-governmental organizations can offer many public policy benefits. When direct governmental provision has predominated, however, achieving these benefits requires building the supply of non-governmental service providers, which requires understanding how to improve their availability and quality. Integrating the literature on contracting and mixed delivery, this article specifies three categories of supply-building tactics: creating markets, buying smart, and managing markets. We then report on 10 cities that have nurtured the supply of schools run by non-governmental organizations. We find that cities’ supply-building efforts fall along a continuum from passive to active, and they employ some types of tactics (creating markets, buying smart) more than others (managing markets). Differential changes in market share across the cities we studied suggest a relationship between supply-building activities and movement from exclusive governmental provision toward the mixed delivery of schools. These findings suggest hypotheses for future research on governmental efforts to build the supply and capabilities of non-governmental service providers in order to pursue mixed service delivery. 相似文献

Scholars disagree whether local decision making is inherently more democratic and sustainable than centralized governance structures. While some maintain it is, due to the incorporation of local knowledge, citizen decision makers' closeness to the issues, and the benefits of participatory democracy, others find it as susceptible to issues of corruption and poor implementation as any other scale. We argue that with wetlands, a natural resource with critical local benefits, it is imperative to incorporate local governance, using the U.S. state of Connecticut as an example. Despite the American policy of No Net Loss, the local benefits of wetland resources cannot be aggregated on a national scale. Each local ecosystem needs wetland resources to ensure local ecological benefits such as flood control and pollution remission, as well as the substantial economic benefits of recreation. We illustrate the benefits of local control of wetlands with data from the American state of Connecticut, which consistently surpasses the federal wetland goal of No Net Loss due, we argue, to the governance structure of town‐level wetlands commissions. A national policy such as No Net Loss, where wetlands are saved or created in designated areas and destroyed in others, is insufficient when it ignores critical benefits for localities. The Connecticut system using local volunteers and unpaid appointees is a successful method for governing common‐pool wetland systems. In the case of Connecticut, we find that local decision making is not a “trap,” but instead an effective model of sustainable, democratic local governance. 相似文献
