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

Abstract Relations between Russia, Ukraine and Belarus and NATO have placed more emphasis on cooperation than confrontation since the Cold War, and Ukraine has begun to move towards membership. At the popular level, on the evidence of national surveys in 2004 and 2005, NATO continues to be perceived as a significant threat, but in Russia and Ukraine it comes behind the United States (in Belarus the numbers are similar). There are few socioeconomic predictors of support for NATO membership that are significant across all three countries, but there are wide differences by region, and by attitudinal variables such as support for a market economy and for EU membership. The relationship between popular attitudes and foreign policy is normally a distant one; but in Ukraine NATO membership will require public support in a referendum, and in all three cases public attitudes on foreign policy issues can influence foreign policy in other ways, including the composition of parliamentary committees. In newly independent states whose international allegiances are still evolving, the associations between public opinion and foreign and security policy may often be closer than in the established democracies. 相似文献

Many researchers blame voter registration requirements for inequalities in turnout rates across various groups in U.S. society. The number of states with election-day registration (EDR) of voters doubled between the 1990 and 1994 elections, providing a unique opportunity to examine its impact on turnout inequality across demographic groups. The adoption of EDR is found to be associated with large and significant improvements in the turnout rates of young persons relative to older persons, and of recent movers relative to nonmovers. Turnout inequality by income class also declines with EDR adoption, but not by a significant amount in multivariate tests. The adoption of EDR does not improve equality of representation across educational levels. 相似文献

Population drug use in Australia: a wastewater analysis 总被引:1,自引:0,他引:1

Accurate information on drug use in communities is essential if health, social and economic harms associated with illicit drug use are to be addressed efficiently. In most countries population drug use is estimated indirectly via surveys, medical presentations and police and custom seizures. All of these methods have at least some problems due to bias, small samples and/or long time delays between collecting the information and analysing the results. Recently the direct quantification of drug residues in wastewater has shown promise as a means of monitoring drug use in defined geographical areas. In this study we measured 3,4-methylenedioxymethamphetamine (MDMA), methamphetamine and benzoylecgonine in sewage inflows in metropolitan and regional areas of Australia and compared these data with published European data. Cocaine use was small compared to European cities (p<0.001) but was compensated for by much greater consumption of methamphetamine (p<0.001) and MDMA (p<0.05). MDMA was more popular in regional areas (p<0.05) whereas methamphetamine and cocaine were mainly consumed in the city (p<0.05). Greater than 5-fold increases in MDMA use were detected on weekends (p<0.001). This approach has the potential to improve our understanding of drug use in populations and should be further developed to improve prevention and treatment programs. 相似文献

Depoliticising development: The uses and abuses of participation 总被引:1,自引:0,他引:1
Sarah C White 《Development in Practice》1996,6(1):6-15
Participation must be seen as political. There are always tensions underlying issues such as who is involved, how, and on whose terms. While participation has the potential to challenge patterns of dominance, it may also be the means through which existing power relations are entrenched and reproduced. The arenas in which people perceive their interests and judge whether they can express them are not neutral. Participation may take place for a whole range of unfree reasons. It is important to see participation as a dynamic process, and to understand that its own form and function can become a focus for struggle. 相似文献
