The purpose of this article is to examine the attitudes and substance use behaviors of African American adolescents living in the Midwest. A baseline survey was administered to 463 African American teens between the ages of 11-19. The article examines the relationship between attitudes toward drugs and drug-using behavior in this African American sample. Drug use will be compared to national drug use norms established by the Youth Risk Behavior Surveillance Survey. Overall participants had fairly negative attitudes toward drugs. Sixty percent of the sample reported that they were committed to a drug-free life, 74% had made a decision to stay away from marijuana, 79% reported making a decision not to smoke cigarettes, and 71% reported they would not get drunk in the next year. Females were more likely to stay away from marijuana than males. In this current study there is cause for alarm; participants reported higher percentages of ever smoking cigarettes and marijuana than the Youth Risk Behavior Surveillance Survey. This study shows there is a need to provide substance abuse prevention programs for African American adolescents. Limitations and future directions are also discussed. 相似文献

The climate of school classrooms, shaped by a combination of teacher practices and peer processes, is an important determinant for children's psychosocial functioning and is a primary factor affecting bullying and victimization. Given that there are relatively few theoretically-grounded and validated assessment tools designed to measure the social climate of classrooms, our research team developed an observation tool through participatory action research (PAR). This article details how the assessment tool was designed and preliminarily validated in 18 third-, fourth-, and fifth-grade classrooms in a large urban public school district. The goals of this study are to illustrate the feasibility of a PAR paradigm in measurement development, ascertain the psychometric properties of the assessment tool, and determine associations with different indices of classroom levels of relational and physical aggression. 相似文献

This paper explores empirically the relation between special-interest groups and economic growth. Our analysis exploits new data on the number of groups observed across countries and time, in order to mitigate the identification problems associated with earlier studies. Also in contrast to earlier work, we examine the impact of groups on two sources of growth??capital accumulation and technological change??in addition to the impact of groups on output growth. The findings are consistent with Olson??s (The rise and decline of nations: the political economy of economic growth, stagflation, and social rigidities. New Haven, Yale, 1982) claim that societies with greater numbers of interest groups grow slower, accumulate less capital, and experience reduced productivity growth relative to others. 相似文献

Abstract: The design and preliminary characterization of a novel sensor for drugs of abuse, DETECHIP®, is described in this proof‐of‐concept note. Combining both colorimetric and fluorimetric assays, DETECHIP® is suitable for lab and field use. More than a conventional spot test which provides a single “yes or no” answer, DETECHIP® provides twenty responses for a more complete characterization of suspect material. This is accomplished by visually noting colorimetric and fluorescent changes of carefully selected dyes upon the addition of test analytes, including drugs of abuse, with respect to controls. Color and fluorescence changes are recorded numerically so that a 20 digit identification code can be constructed for comparison of test analytes and known compounds. DETECHIP® is applicable to a variety of drugs, both plant‐derived and synthetic, addressing the need to use several different spot tests simultaneously for a single sample. 相似文献

There is a clear trend for law and regulation, particularly in cyberspace, to become increasingly precisely specified. The perceived benefit of this approach, increased certainty as to compliance, may be illusory. Over‐complex laws have serious disadvantages, particularly a greatly weakened normative effect, and problems of contradiction and too‐frequent amendment. The combined effect of these disadvantages can be to produce a ‘bad’ law system, assessed in terms of Fuller's internal morality of law. It may also result in a law‐system which substantially fails to achieve its intended aims. This article proposes that these defects can be cured by abandoning the search for precision and substituting a method of lawmaking which requires the law's subjects to make their own qualitative assessments of whether they are meeting the obligations imposed on them. This will make the law more easily understandable by those to whom it applies, and will also increase the normative effect of cyberspace law. 相似文献

Self-harm and violence in women’s prisons in England are common and occurring with increasing frequency. We aimed to describe the characteristics and patterns of violent and/or self-harming behaviours in women in prison by conducting a retrospective analysis of routine data about self-harm incidents and adjudications. Incidence rates of self-harm and violence were calculated and associated factors explored using logistic regression. We found that only 6.7% of 5486 women prisoners self-harmed and 7.9% had been violent. Eighty per cent of all self-harm incidents related to 70 women. Almost 4 in 10 women prisoners who self-harmed were also violent. Multiple incarcerations and court movements are associated with incidents of self-harm and violence. Women with high-frequency self-harm (≥6) began self-harming early in their custodial period. We conclude that women prisoners who are very behaviourally disturbed can and should be identified early. They warrant clinical formulation and multi-agency responses to risk. Those with high-frequency self-harm should be cared for by external health services. 相似文献

Objective
We examine the relationship between early criminal involvement and school dropout, and analyze which factors underlie this relationship, making use of administrative data from the Netherlands.Methods
We start by determining the unconditional correlation between early criminal involvement and school dropout, using a basic ordinary least squares model. As this association is likely to be driven by different factors, we proceed by including an extensive set of observable family and individual characteristics into the estimation model. We further proceed to models that account for the influence of unobservable heterogeneity by estimating school, class, sibling and twin fixed effects.Results
Criminal involvement is associated with an 11 percentage point higher probability of school dropout. The magnitude of this relationship decreases gradually when we account for larger shares of observed and unobserved heterogeneity. The coefficient in the same-gender twin fixed effects model indicates a 3 percentage point higher probability of school dropout, which is statistically significant at a 10 % level. We also find that the association between criminal involvement and school dropout is stronger if juveniles are involved in severe criminal activities.Conclusions
We conclude that the observable and unobservable factors for which we account explain around 73 % of the unconditional correlation between criminal involvement and school dropout. The remaining variation likely reflects individual-specific characteristics that are different between same-gender twins. A true treatment effect, if existing, is likely to be relatively small. At the same time, serious criminal behavior appears to causally affect school dropout.209.

The emergence of “mega-regional” trade agreements has recently become the most significant trade policy issue in the Asia-Pacific. Since 2010, governments in the region have launched negotiations for two new trade agreements: the United States-led Trans-Pacific Partnership (TPP) and the ASEAN-led Regional Comprehensive Economic Partnership (RCEP). Differentiated by their membership, scope and level of ambition, the TPP and RCEP embody competing visions for how the Asia-Pacific trade system should evolve, and regional governments must now make choices over which initiative better serves their economic and political interests. This article explores the trade policy choice posed by these mega-regional trade negotiations, reviewing the evolution of the Asia-Pacific trade system, the recent emergence of the TPP and RCEP, and the competitive dynamics inherent in the development of the two proposals. It argues that four key considerations (trade policy ambition, the role of ASEAN, US-China geopolitical rivalry and defensive concerns) will be of key importance in informing regional governments’ decisions as the TPP and RCEP move towards completion in 2015. 相似文献

While a new working class is in the process of remaking itself in China, the latest trend in labour studies has rejected the Marxist tradition which sees the social relations of production as the point of departure for analysing workplace conflict. According to the new current, influenced by post-structuralism, class is only one of the identities articulated by workers, and it can be understood only with reference to their discourses. By critically evaluating an important book by Ching Kwan Lee (Against the Law: Labor Protests in China's Rustbelt and Sunbelt), this article suggests that her approach generalising workers' protests with the notion of citizenship cannot satisfactorily explain the changing pattern of labour protests in China since 2004. By using fieldwork data and connecting the analysis of the social relations of production with the changing patterns of workers' struggle, this paper argues that migrant workers protests are a significant part of the emerging class conflict in China. 相似文献
