Recent media attention has increased interest in behavioral, mental health, and academic correlates of involvement in bullying. Yet, there has not been much interest in investigating the co-occurrence of other health-risk behaviors, such as gang membership, weapon carrying, and substance use. The potential influence of contextual factors, such as youth ethnicity, urbanicity, and school characteristics, also has been overlooked in previous research. The current study examined different subtypes of involvement in bullying—as primarily a victim, as primarily a bully, as both a victim and bully, and no involvement—and the association with significant health-risk behaviors, including engaging in violence and substance use, as well as academic problems. The analyses use self-report data from 16,302 adolescents (50.3 % female, 62.2 % Caucasian, 37.8 % African American) enrolled in 52 high schools. A series of three-level HLM analyses revealed that bullies and bully/victims were generally at greatest of risk of being involved in violence, engaging in multiple types of substance use, and having academic problems. These findings extend prior research by emphasizing a potential link between involvement in bullying and multiple health-risk behaviors, particularly among urban and African American high school youth.  相似文献

A newspaper's ‘Letters to the Editor’ column represents its readership in a unique way and can provide a useful ‘thermometer’ with which to measure the extent of critical debate and discussion a particular issue generated in a locality. In this article, the letters of women to the editor of the Aberdeen Daily Journal, 1900 to 1914, are analysed to discover the type of political issues with which these women concerned themselves. It is argued that the women must have felt particularly strongly about such issues since they were prepared to take their arguments outside their social circle and to identify themselves as politically active in the pages of their daily newspaper. Political issues dealt with include local government, the suffrage question and government legislation. While much of the evidence used comes from the letters of active suffragists who were usually members of national suffrage associations, it is argued that the period showed an expansion in the type of woman interested in politics, and the corresponding urge to write to the newspapers. This is evidenced in the number of women who firmly stated that they were not suffragists, but became politicised enough to write to the newspaper complaining about the Insurance Act in 1912.  相似文献

Despite domestic opposition and several policy alternatives, in 2001 the Russian government adopted a pension reform that was potentially costly and had uncertain long-term benefits. Demographic and fiscal pressures created the desire to reform and a more cooperative Duma made it possible to do so. These points do not explain why Putin chose the pension privatisation option. Russia's pension reform is best understood as part of a state-building strategy to diminish the role of powerful bureaucracies. Russia's welfare state was not merely the product of a powerful and popular president, but rather a tool to create a stronger executive.  相似文献

Numerous scholars note the highly gendered nature of anti-trafficking responses. Much of the literature exploring anti-trafficking campaigns, however, focuses on the objectification of women and their placement as abject bodies, objects of violence, in pain and to be pitied. Nevertheless, few scholars explore how these campaigns portray men and shape masculinities. Using as example a highly publicised online anti-trafficking campaign, ‘Real Men Don't Buy Girls’, this article responds to this gap in the literature by exploring depictions of masculinities through this prominent anti-trafficking public service announcement. The article observes that this announcement serves not to reshape gender performance around trafficking, but instead further reproduces existing gender structures and power relations underpinning trafficking and child exploitation. It observes that the campaign re-instantiates hegemonic masculinities – framing men enacting this masculine form as ‘real men’ – while encouraging men to embody a virile, successful, consumerist, controlling, and patriarchal manliness. We observe that these characteristics are notably assigned to celebrity men. Meanwhile, it is noted that men who buy girls are set in binary opposition to these real men, being shaped as faceless, un-described, deviant, and ‘unreal’. The result is that the campaign not only patterns masculinities, but also objectifies the objectifier as well as women, recreating a gender ordering in which women and girls remain disempowered, and buyers of girls are ultimately denied subjecthood and thus the ability to change. This article, therefore, uses this one case study to call for anti-traffickers, researchers, and scholars to urgently consider, research, and reshape portrayals of masculinities in anti-trafficking literatures. It calls for greater diversity and fuller account for a broader spectrum of gender representations in the visual representations of those involved in, and responding to, human and child trafficking, in both our scholarly work and public action.  相似文献

Previous studies suggest cardiovascular pathologists are less accurate than noncardiovascular pathologists (e.g., clinical pathologists) in estimating the degree of coronary artery stenosis. To further investigate the effect of training on accurate estimation of coronary artery stenosis, we designed a study to compare the accuracy of estimates made by forensic pathologists versus medical students. Six forensic pathologists and twelve medical students each independently examined 24 images of coronary artery cross sections and gave an estimate of the degree of stenosis. When comparing all 24 images, the forensic pathologists had a median difference between the estimated percentage of stenosis and actual percentage of stenosis of −12.380 and the medical students had a median difference of −16.50 (p-value of 0.08542). In estimating the percentage of stenosis, training in forensic pathology does not guarantee significantly improved accuracy compared with medical students. Our study showed no consistent statistically significant difference between estimates given by forensic pathologists and by medical students.  相似文献

We replicatethe most recent unpublished extension by Dr. Groseclose andresearch assistants for years 1947–1999, and then we extendthe analysis to include years 2000 through 2007. We make availableinflation-adjusted ADA scores from 1947 through 2007, allowingscholars to incorporate the most recent interest group scoresinto their analyses. Author's Note: Authors are listed alphabetically. The authorswish to thank Tim Groseclose for making available both the nominalADA scores from 1947 to 1999 and the Matlab program files usedin this analysis.
