Cocaine (COC) is a highly addictive plant alkaloid expressing strong psychostimulatory effect. It has no medical use in equine veterinary practice. The contamination of the environment with cocaine such as its presence on the US paper currency has been reported few times. There are anecdotal reports of low benzoylecgonine (BE) concentrations (usually much less than 100 ng/mL) being found in urine of race horses. In order to protect horsemen against harsh penalties associated with the presence of trace amounts of BE in horse urine as a result of environmental contamination, in February 2005 the Illinois Racing Board issued new medication rules that established the threshold level of 150 ng/mL for BE in equine urine. The penalties associated with this rule provide for increasing fines ($250, $500, $1000) with successive positive reports against a trainer for levels of BE below 150 ng/mL. A total of 19,315 urine samples were collected over the 2-year period of time from winning horses (both harness and thoroughbred) at race tracks in Illinois for routine drug screening (ELISA). The presence of BE was confirmed by GC/MS in 28 urine samples (0.14%). The concentration range for BE in harness horses (21 detections) was < 5-91 ng/mL, and for thoroughbred (seven detections) was 7-52 ng/mL. To date, the laboratory has not reported concentrations of BE that exceed the established threshold concentration of 150 ng/mL. 相似文献

Youth gangs have received substantial scholarly and public attention during the past two decades. Although most of the extant research on youth gang members has focused on their offending behaviors, recent studies have examined the victimization of youth gang members relative to their nongang peers. Gang members generally have been found to be at increased risk of victimization, although the reasons for this relationship have not fully been explored. The current study uses data from a multisite study of youth to explore whether the gang membership-victimization link is mediated by lifestyles and routine activities. In other words, is gang members' involvement in delinquent lifestyles and routine activities a viable explanation for their increased risk of serious violent victimization? Implications of these findings and suggestions for future research and policy are discussed. 相似文献

Using data from the Teaching, Research, and International Policy (TRIP) project, we address several questions posed by students of the international relations (IR) discipline, specifically, whether and to what extent: US scholars, institutions, and journals dominate the field; national communities of IR scholars are insular or inward-looking; and/or the discipline is theoretically, methodologically, and epistemologically diverse. We draw from two major data sources: a series of cross-national surveys of IR faculty in thirty-two countries and a database of journal articles published in the twelve leading IR journals from 1980 to 2014. We find obvious signs of US hegemony and insularity. Other national IR communities are relatively open to foreign ideas, if not to hiring scholars trained in other countries. Finally, despite US hegemony in the discipline and pockets of geographic insularity, we see a diverse field characterized by a wide range of theoretical, methodological, and epistemological commitments. We conclude with a discussion on the sources and consequences of diversity in the international relations discipline. 相似文献

AbstractThe election of Donald Trump in 2016 sent shock waves across political classes globally and prompted debates about whether his ‘America first’ agenda threatened the liberal international order. During his first year in office, Trump seemed determined to undermine the hallmarks of the liberal international order: democracy, liberal economics and international cooperation. So, are we witnessing the emergence of a “post-liberal” and “post-American” era? Four sources of evidence help frame – if not answer – the question: history, the crisis of liberal democracy, Trump’s world view, and the power of civil society (globally and nationally) to constrain any US President. They yield three main judgements. First, continuity often trumps change in US foreign policy. Second, the liberal international order may have been more fragile pre-Trump than was widely realised. Third, American power must be put at the service of its own democracy if the US is to become the example to the world it used to be. 相似文献

How campaigns shape voters' decisions is central to the study of political behavior. The basic conclusion is simple: campaigns matter. While we know who campaigns influence, there is no clear empirical evidence of why or how campaigns matter. This comes from two things. First, despite different theories about campaigns, the existing studies measure the campaign as a function of time. Second, these studies ignore the individual-level psychological mediators of these effects. We know that there are differences across time during a campaign, but we do not know how or why. In this article I suggest that campaigns work by altering voters' uncertainty about the candidates and combine aggregate and individual-level data using a hierarchical logit estimated via Markov chain Monte Carlo methods. I find that voters change how they weigh their attitudes during the campaign because of changes in their uncertainty about the candidates. 相似文献

Empowerment has become an influential concept and theoretical framework for social policy and practice. Still, relatively
little is known about the roles that empowerment plays in the ecology of human development, particularly among young people.
This article reports results of a study of psychological empowerment among young people, using data from 629 high school students
(65.8% female; 96.5% non-white). Using a path analysis, we examined the role of perceived sociopolitical control—an indicator
of the intrapersonal component of psychological empowerment—as a mediator between ecological support systems and developmental
outcomes. Findings confirmed that social support in family, peer, and school settings, and family cohesion positively predict
self-esteem and perceived school importance, which, in turn, have protective effects on psychological symptoms, violent behaviors
and substance use. Sociopolitical control was found to mediate the relationships between ecological supports and risk factors
and developmental outcomes, leading to the conclusion that perceived efficacy in the sociopolitical domain, and youth empowerment,
more generally, should be considered as core elements of the ecology of human development. Policy and practice aimed at promoting
positive developmental outcomes and preventing risk behaviors should take their relationship to sociopolitical control into
account. 相似文献

As more and more political institutions stress the significance of gender equality policies, it becomes important to investigate the different interpretations and meanings attached to the concept of gender equality in diverse policy contexts. In this article we are interested in problematizing visions of gender equality by studying the challenges that the growing amount of paid domestic work performed within European households poses for gender equality policies and practices in two European countries. The aim is to reveal normative assumptions and silences in relation to gender equality by comparing how “paid domestic work” has been framed in policy debates in Sweden and Spain. As welfare states, Sweden and Spain are generally considered to be very different, and in policies on care for children and the elderly the differences are perhaps most apparent. In both countries, however, paid domestic work in the home has become more and more common in the last two decades. The rise of paid domestic services in European households has been interpreted as due to the limitations or decline of welfare states, the ageing populations, and the increasing numbers of dual-earner families. These services are most often provided by women, predominantly of immigrant background, and involve a wide range of tasks, including care work. The phenomenon of an increasing sector of domestic (care) work poses a theoretical and methodological challenge to gender and welfare studies. This article argues that the analysis of debates surrounding domestic service in private households is a useful starting-point for an intersectional analysis by means of revealing the normative assumptions and marginalization embedded in gender equality policies. It uses a comparative frame analysis in combination with intersectional analysis to assess how interactions between gender, class, race, and sexuality have been articulated in the policy debates on domestic services in Spain and Sweden. 相似文献
