The natural emergence of status hierarchies in adolescent peer groups has long been assumed to help prevent future intragroup aggression. However, clear evidence of this beneficial influence is lacking. In fact, few studies have examined between-group differences in the degree of status hierarchy (defined as within-group variation in individual status) and how they are related to bullying, a widespread form of aggression in schools. Data from 11,296 eighth- and ninth-graders (mean age = 14.57, 50.6 % female) from 583 classes in 71 schools were used to determine the direction of the association between classroom degree of status hierarchy and bullying behaviors, and to investigate prospective relationships between these two variables over a 6-month period. Multilevel structural equation modeling analyses showed that higher levels of classroom status hierarchy were concurrently associated with higher levels of bullying at the end of the school year. Higher hierarchy in the middle of the school year predicted higher bullying later in the year. No evidence was found to indicate that initial bullying predicted future hierarchy. These findings highlight the importance of a shared balance of power in the classroom for the prevention of bullying among adolescents.  相似文献

The fact that disadvantaged people generally die younger and suffer more disease than those with more resources is gaining ground as a major policy concern in the United States. Yet we know little about how public values inform public opinion about policy interventions to address these disparities. This article presents findings from an exploratory study of the public's values and priorities as they relate to social inequalities in health. Forty-three subjects were presented with a scenario depicting health inequalities by social class and were given the opportunity to alter the distribution of health outcomes. Participants' responses fell into one of three distributive preferences: (1) prioritize the disadvantaged, (2) equalize health outcomes between advantaged and disadvantaged groups, and (3) equalize health resources between advantaged and disadvantaged groups. These equality preferences were reflected in participants' responses to a second, more complex scenario in which trade-offs with other health-related values - maximizing health and prioritizing the sickest - were introduced. In most cases, participants moderated their distributive preferences to accommodate these other health goals, particularly to prioritize the allocation of resources to the very sick regardless of their socioeconomic status.  相似文献

Between 2004 and 2008 the Forensic Isotope Ratio Mass Spectrometry (FIRMS) network organised four Inter-Laboratory Camparison excercises with the aim of harmonising and validating isotopic measurements to be used for forensic applications.The samples distributed comprised materials of potential forensic interest such as packaging and pharmaceuticals to be analysed for δ2H, δ13C, δ15N and δ18O composition. As many as 30 international laboratories participated in these comparisons. Results have shown overall improvements for both within- and inter-laboratory reproducibility with respect to δ13C and δ15N measurements.Only a small number of laboratories returned results for δ2H and δ18O analysis and these results highlighted a need for improvement in the reproducibility of these measurements and a need to address the exchange of hydrogen between samples and ambient moisture. Results also highlighted the importance of sample preparation procedures and the need to standardise both these procedures and calibration against Standard Reference Materials. Future Inter-Laboratory Comparison exercises will assess the suitability of laboratories to submit data to national and international databases similar to those currently operated for fingerprints, DNA etc.  相似文献

Indirect forms of government have become increasingly prominent in Turkey over the last few decades. After giving an overview of the growing role of non-public actors in Turkish policy-making, we depart from the common idea that the phenomenon is a result of neoliberalism only and examine the multiple genealogies and complex dynamics at work. The paper then questions the preconception according to which the involvement of non-public actors implies a retreat of the state and frames these developments in terms of changing forms of government. Finally, we question the outcomes of this phenomenon in terms of policy and power reconfigurations.  相似文献

This article considers the problem of extraterritorial human rights violations committed by transnational corporations (TNCs), and draws on Crouch's framework in Post‐democracy to illustrate why the issue has proved so difficult for states to regulate. I begin by examining the problem of corporate regulation more generally, and set out Crouch's analysis to show why and how corporations have become so influential. The second section considers the area of business and human rights, and explains why there is ‘a governance gap’ in relation to extraterritorial human rights violations committed by corporations. The third section describes efforts at the international and domestic levels to regulate corporations in relation to this issue. It concludes that while new international principles and innovative hybrid schemes are playing a valuable role in norm creation and standard‐setting, the enforcement of these principles remains limited. Corporations have largely succeeded to date in their lobbying efforts to remain free of any direct obligations under international law.  相似文献

The Greenbook Initiative has acted as a catalyst for change across the United States and globe. In this article, the authors discuss how the Greenbook has shaped the environment related to perpetrator accountability in child welfare, how a paradigm shift in work with fathers can advance domestic violence‐informed practice, and how a perpetrator pattern‐based approach, as exemplified by the Safe & Together Model, can help advance the vision of the Greenbook.  相似文献
