Schools across the country are ending the practice of grouping students based on ability, in part, because of research indicating that tracking hurts low-ability students without helping students of other ability levels. Using a nationally representative survey conducted by the National Center for Education Statistics, (NCES) we reexamine the impact of tracking on high school student achievement through the estimation of a standard education production function. This approach allows us to control for the possibility that track is correlated with factors such as class size and teacher education. In addition, we address the possibility that there are unobserved student or school characteristics that affect both achievement and track placement. Our results indicate that abolishing tracking in America's schools would have a large positive impact on achievement for students currently in the lower tracks, but that this increase in achievement would come at the expense of students in upper-track classes. 相似文献

Great Britain's decision to withdraw its forces from Southeast Asia by the mid-1970s created uncertainty for those living in the region. The potential loss of British presence led Australia to attempt to discourage Britain from leaving, while also recsognising recognising the decision as an opportunity to re-evaluate Australia's strategic outlook in Southeast Asia and the Pacific. Scholars have treated Asia and the Pacific as two regions with distinct experiences related to withdrawal. Some address changing Anglo-Australian relations but include little, or no, mention of the Pacific territories. Others, writing about the Pacific, focused more the individual paths taken by each island than on connecting the larger process of decolonisation in the Pacific to the one in Asia. This article pairs Australia's Strategic Basis of Defence papers with documentary evidence across multiple departments in Canberra to understand how British withdrawal from east of Suez connected Australian concerns about security in Southeast Asia and the Pacific Islands. By connecting the two areas through Australian interests, the withdrawal from east of Suez can be understood as a catalyst for Australia's pursuit of a distinctive role within its neighbourhood. 相似文献

This article first reviews and compares Human Rights Council and University Period Review (HRC/UPR) research published during and shortly after the institution-building period (2006–2009) to more recent work (2010–2014) to identify patterns of scholarly interest in NGO roles and behavior at the HRC/UPR. It divides research into that which either “ignores” NGOs or offers “indirect” attention, “direct” attention, or “foregrounds” NGO activity, concluding that NGOs are surprisingly underexamined, given remarkable new participatory opportunities in the HRC/UPR and the centrality of NGO information provision to the success of the new body. Empirical analysis of NGO statements from the CHR to the HRC indicates sharply increasing NGO participation, particularly among domestic, regional, and Southern NGOs. The increased volume and changing characteristics of participating NGOs may have important effects on the HRC/UPR and should also encourage further analysis. 相似文献

Now in its sixth year, the war in Syria has triggered the largest humanitarian and refugee crisis of our time. For most refugees and migrants, Turkey is the main transit country to reach Europe, where Syrian refugees hope for a better future. However, this journey has been hampered as several European countries closed their borders following the arrival of an unprecedented number of migrants and asylum seekers in 2015. In response, a deal was struck with Turkey to stem the migrant flow to Europe in exchange for some concessions. By outsourcing the management of migration flows to Turkey, the EU is failing to take its fair share of responsibility for refugee protection. Furthermore, as a result of the political situation in Turkey and the unmet promises under the deal, relations between Turkey and the EU have touched their lowest point since the start of accession negotiations in 2005. While survival of the deal is of critical importance as the EU needs Turkey’s assistance in curbing migration flows and Turkey is keen on revitalising its accession negotiations, the deal has exposed serious flaws that need to be addressed and must not be replicated with other countries. 相似文献

Developmental imbalance models attribute the rise in risk-taking during adolescence to a universal imbalance between rising reward sensitivity and lagging cognitive control. This study tested predictions of an alternate Lifespan Wisdom Model that distinguishes between exploratory/adaptive (e.g., sensation seeking) and maladaptive (e.g., acting-without-thinking, delay discounting) risk-taking propensities and attributes the latter to a sub-set of youth with weak cognitive control. Latent trajectory modeling of six waves of data from 387 adolescents (52% females; spanning average ages of 11–18 years) revealed distinct sub-groups with heterogeneous trajectory patterns for acting-without-thinking and delay-discounting. Only those trajectory groups with weak cognitive control, characterized as “high-increasing” acting-without thinking and “high-stable” delay discounting were predictive of a maladaptive risk-taking outcome, namely substance use disorder. Sensation seeking demonstrated a universal peak, but high levels of sensation seeking were not associated with weakness in cognitive control and were unrelated to substance use disorder, controlling for impulsivity. The findings suggest that maladaptive risk-taking characterized by weak cognitive control over reward-driven impulses is a phenomenon limited to only a sub-set of youth. 相似文献

Although media exposure has been related to cognitive preoccupation with appearance, research rarely investigated adolescents’ behavioral self-sexualization. To address this gap, the present study among 12- to 16-year-olds (N?=?1527; 50.2% girls) in Austria, Belgium, Spain, and South-Korea (1) investigates whether different types of media use relate to self-sexualization, (2) explores the explanatory value of rewarded appearance ideals, and (3) considers culture and gender as moderating factors. Despite cultural variation, a general trend of increasing self-sexualization with social media use and magazine reading appeared across the countries. Moreover, women’s magazine reading and rewards were related to self-sexualization among all the girls across the countries, which suggests that girls may be more vulnerable to the examined effects. Overall, this study provides a better understanding of the unique contribution of specific media genres to youth’s self-sexualization and points at the importance of social media use in girls’ and boys’ engagement in sexualizing appearance behaviors across four countries. 相似文献

The goal of the current study was to examine the protective role that maternal media monitoring might have for adolescents. This was done by considering whether styles of media monitoring either directly reduced media use, or whether they buffered the associations between aggressive media use and adolescents’ prosocial behavior, aggression, and delinquency. Participants were 681 adolescents from two cities in the United States (51% female; 73% white), and their mothers, who provided data at two different time points, 2 years apart (when adolescents were roughly ages 13 and 15). Mixture modeling results revealed that mothers used four different styles of media monitoring made up of combinations of active and restrictive monitoring as well as forms of co-use. Styles that included active monitoring and connective co-use (i.e., engaging in media with the intent to connect with children) were directly associated with less media use, and moderated links between adolescents’ media use and behavioral outcomes concurrently but not longitudinally. The discussion was focused on the strength of considering multiple strategies of media monitoring together, and how this approach can inform future research in the area of parental media monitoring. 相似文献
