Sororities have been identified as placing young women at risk for body image concerns due to a focus on traditional gender role norms and objectification of women. Objective: This study assessed the relationship between conformity to feminine gender role norms, self-objectification, and body image surveillance among undergraduate women. Participants: In a random sample of undergraduates, the authors examined data from sorority and nonsorority women. Methods: In a random sample of undergraduate women, the authors assessed the impact of traditional feminine gender role norms on self-objectification, body image, and feedback regarding physical appearance for sorority and nonsorority undergraduate women. Results: Three linear regressions were conducted, and only conformity to feminine gender role norms contributed significantly in each regression model. Conclusions: Regardless of sorority membership, conformity to feminine gender role norms was found to significantly contribute to increased body consciousness, negative body image, and feedback on physical appearance.  相似文献

In this paper, we examine whether county-level measures of poverty and social disadvantage are correlated with county-level variation in the black/white foster care placement gap. The black/white placement gap refers to the fact that when the rate of placement into foster care for black children is compared to the rate for white children living in the same area, the black placement rate is almost always higher than the rate for whites. Although differential exposure to poverty is often used to explain why the placement gap is so large, the problem has rarely been studied. Using Poisson event count models, we find that poverty, measured at the county ecological level, is associated with a narrower gap rather than a wider gap. The counterintuitive finding is due to the fact that the relationship between poverty and placement rates depends on race.  相似文献

Forecasts of materials damage from air pollution require (a) knowledge of a “damage function,” (b) an estimate of the exposure of materials to pollutants and other factors that enter into the dose relationship, and (c) the quantity and characteristics of the exposed materials. Uncertainty about any of these factors can lead to unacceptable uncertainty or bias in damage forecasts. Particular attention is given to the influence of the spatial units used to derive forecasts of materials damage. Environmental corrosion can vary significantly over relatively small geographic areas; accordingly, the choice of spatial unit can have an impact on forecasts of damage. The environmental factors that influence materials damage may not be independent over the time of exposure. There appears to be some evidence, for example, that SO2 is not independent of time of wetness, both factors in metal corrosion.  相似文献

As dynamic collaborations between networks of specialists have become more central to developing cutting-edge innovations, designing and sustaining innovation policies that foster them has become an increasingly central concern. This article reviews the characteristics of the “developmental network” or “neo-developmental” states that have been shown to foster innovations at the technological horizon. It then analyzes the US case to suggest why some developmental network approaches to governance have proven relatively durable, while others have not. We conclude with a discussion of what can – and cannot – be learned from the US case, and suggest the importance of comparative work on the sustainability of effective innovation-centered approaches to governance.  相似文献

美国环保协会的故事开始于50多年前一场关于保护鸬鹚,一种可爱的鸟类的运动。上世纪60年代,美国长岛的科学家惊讶地发现当地鸬鹚幼鸟的数量由于不知名的原因,急剧下滑至正常数量的七分之一。与此同时,秃头鹰、游隼等其他猛禽的数量也出现了同样惊人的跌幅。其中一些科学家通过科学研究追踪问题的根源,发现喷洒杀虫剂DDT(又称“滴滴涕”)是造成这一现象的罪魁祸首。在通过科学的指证赢得了在美国全面禁止DDT使用的官司之后,为了进一步保护人类赖以生存的自然环境,这些科学家成立了美国环保协会。  相似文献

The purpose of this study was to test a model of job control, work pressure and strain in two samples in the USA and in The Netherlands. According to the proposed model, work pressure has a mediating role between job control and worker strain. The present model specifies three types of job control: task or instrumental control, conceptual or resource control, and decision organization control. Task and resource control are assumed to reduce the stressor of work pressure which, in turn, is related to high strain. Organization control is assumed to be positively related to work pressure. The model was tested in two samples : one US sample of 273office employees and one Dutch sample of 958 employees in a variety of jobs. The same measure of job control was used in both samples. Resultspartially confirm the proposed model. As predicted by the proposed model, high task control was related to low work pressure, whereas high organization control was related to high work pressure. The effects of task control and organization control on strain were mediated by work pressure for the measure of anxiety in the US sample and for the measure of stress in the Dutch sample. However, the mediating effect of work pressure was not found for job satisfaction in both samples, for the measure of mood disturbances in the US sample and for the measure of sick days in the Dutch sample. The proposed model is only partially confirmed by the results. These results confirm the importance of differentiating between different dimensions of job control.  相似文献

Out of touch: local government and disabled people's employment needs   总被引:1,自引:1,他引:0  
In autumn 2003 we contracted to undertake a study in two district council areas of ways in which they could meet their Local Public Service Agreement (LPSA) targets in respect of disabled people returning to work. We undertook a literature review of barriers to work, interviewed a number of people involved in working with unemployed people and a number of disabled people in these areas. All the employment organisations we had contact with were working to an individual model of disability and the need to change their orientation became the central recommendation of the first phase of this study. This was rejected by those funding the study. At the end of the first year none of the organisations active in this area was able to identify a single disabled person who had returned to work as a result of their help. We conclude that central government policies are doing little to change the perception of the employment needs of disabled people within local government.  相似文献

本文试图总结美国文化人类学的当代理论和方法论.这里所讨论的这些美国人类学的当代观念是基于它们的历史脉络、继承、重现、转变和对立.从20世纪60年代起,在诸如主观性、权力和民族志表述等问题上,人类学理论和方法论发生了许多非常显著的转变和分歧.这种状况起因于人类文化学研究的文学化途径,这种途径是经由格尔茨(Geertz)以及其他学术运动,如英国的文化研究(Cultural Studies),特别是福柯(Foucault)的后现代主义而发展起来的.由此,人类学由来已久的喧嚣的科学和人文之间的对峙已经演绎出独立的认识论阵营,在某些情况下导致了一些大学中人类学系的分离.同时,这种分裂也激发或伴随着一种对当代全球化形势下文化人类学研究对象的定位的承认,比如本土性(indigenous)、下层 (subalterns)研究,确认了这些研究对象在研究项目中具有合法的权利和合作的声音.这种转向使人们愈加关注应用人类学,同时也伴随着许多新的问题,例如"本土知识"的观念.另一个分裂是一些特定的专门研究领域的学科建制,如医学人类学、生态人类学和教育人类学等,而这些领域的每一个又都存在着其内部分歧和区别.这些正在发生的变化引起了对于博厄斯学派所传承下来的诸如文化、文化相对主义等观念的效用和学术规范的质疑.过去的30年是一个骚动激荡、分崩离析的时期,人类学研究在这个时期卷入了全球资本主义的新的文化逻辑的转换之中.  相似文献

Timing effects and the interpretation of period fertility   总被引:1,自引:0,他引:1  
Schoen R 《Demography》2004,41(4):801-819
Low fertility levels and later childbearing in many developed countries have reinvigorated the debate between period and cohort perspectives on fertility and on the meaningfulness of the period total fertility rate (TFR). Here, fertility-timing effects are defined as level changes in period fertility that do not reflect level changes in the completed fertility of cohorts. That definition leads to the average cohort fertility (ACF) as a measure of period fertility adjusted for timing effects. In an influential paper, Bongaarts and Feeney (1998) presented an alternative approach and a different measure, TFR*, to adjust for timing effects. Here, the two measures are compared. In the context of model populations, the ACF performs well, reflecting an average of the fertility of the active cohorts. The Bongaarts-Feeney TFR*, however, is frequently unreliable and can be erratic when there are cycles in period timing. When applied to twentieth-century U.S. experience, the TFR* behaves like a period measure and yields adjustments that are often wide of the mark. The ACF shows the stability associated with cohort measures and quantifies the substantial impact that timing effects had during the "birth dearth" of the 1970s. The period TFR reached a low of 1.74 in 1976, but the ACF never went below 2.06 during the 1970s.  相似文献
