Sport is used as a lens through which ‘white’ people are encouraged to analyse how they construct and view ‘black’ people. Sport is linked to an analysis of the ways that sections of the media have framed tennis champions Serena and Venus Williams as threats. This article examines how key media spokespeople use disparaging racist and sexist stereotypes that no longer focus on female passivity and weakness to denigrate their physical power and mental strength. It argues for a new critical race consciousness that can inform sporting commentary and media narratives to enable African American women and men to envision and achieve equality within a broader framework of social justice.  相似文献

Significant bodies of scholarship have explored family background and its implications for racial/ethnic differences in academic achievement. Much less attention, however, has focused on the ways in which victimization in schools—and bullying in particular—may impact student performance. Drawing on nationally representative data from the Educational Longitudinal Study of 2002 and employing multilevel analysis from four racial/ethnic groups (Asian, black, Latino, and white), this study examines: (1) the impact of bullying on achievement and (2) the extent to which high- or low-achieving students are more vulnerable to bullying. Results indicate that bullying is relatively more frequent among blacks who are higher achievers and that bullying has equally detrimental consequences on later achievement for all racial/ethnic groups considered in this study. These findings are discussed relative to prior research on racial/ethnic inequality, education, and victimization, and also public policy efforts to address bullying in schools.  相似文献

An analysis of human population trends from 2000 to 2010 shows that of the roughly one billion additional people on the planet today, a disproportionate number live in the biodiversity hotspots and tropical wilderness areas (TWAs). Although the annual population growth rate in the hotspots declined from 1.6 to 1.3 %, the total population increased by 187 million people. While less densely populated, the TWAs grew at roughly twice the rate of the hotspots. Overall, slower growth rates are indicative of longer-term global trends in decreasing fertility, aging populations, and increased urbanization. The hotspots, however, are largely inhabited by people who have yet to enter their reproductive years or are in the early stages therein. The young age structure means that populations in these priority conservation areas will grow even as fertility rates fall further, and biodiversity will be forced to share dwindling natural habitat with ever more people.  相似文献

Using 2010 national data, we investigate the relationship between social integration and health insurance for African American adults. During the previous year 21.6% of men and 19.8% of women lacked continuous health insurance. The effect of marital status, income, and employment on insurance coverage differed by age and gender. Additionally, frequency of church attendance was positively associated with continuous health insurance for women aged 51–64. Spiritual/religious identity was marginally associated with insurance status for men aged 36–50. As provisions of the Affordable Care Act take effect, implementation programs should expand enrollment efforts to include the conjugal unit and the church.  相似文献

War films were one of British cinema's mainstays throughout the 1950s, and one of the most iconic of the cycle is Ice Cold in Alex (1958). This particular film overturned some of the already familiar conventions of the genre, not least by allowing a female character, the nursing sister Diana Murdoch (played by Sylvia Syms), to play a more important role than women were usually granted. This article deploys close textual analysis to examine the representation of Diana, and suggests how this character not only reflects various competing and often self-contradictory discourses of 1950s femininity but also offers a rare depiction of women's contribution to the war effort from the decade following it.  相似文献

Construction work is an inherently dangerous occupation and exposure to additional job stressors is likely to exacerbate the level of danger, increasing workers’ risk for injury. Thus, it is important to identify and then reduce worker exposure to extraneous job stressors. This study examines the relationships between a variety of job stressors and injury or near-miss outcomes among construction workers. Self-reported questionnaire data collected from 408 construction labourers (male and female) via telephone interview were analysed using structural equation modelling. A theoretical model was tested whereby work stressors, classified into three groups, could be related, either directly or indirectly through the mediating effects of physical or psychological symptoms/strain, to self-reported injuries and near misses. Ten of the 12 work-related stressors were found to be directly related to either injury or near misses, including: job demands, job control, job certainty, training, safety climate, skill under-utilization, responsibility for the safety of others, safety compliance, exposure hours, and job tenure. Other stressors (i.e. harassment/discrimination, job certainty, social support, skill under-utilization, safety responsibility, safety compliance, tenure in construction) were indirectly related to injuries through physical symptoms or indirectly related to near misses through psychological strain. There was no support for the modelled gender differences. Implications for health and safety on construction sites are discussed.  相似文献

The key question addressed in this research is ‘how can we effectively manage and mobilise knowledge in the extended enterprise?’. We explore how knowledge sharing and transfer occur when developing new products, with special reference to the telecommunications industry. The benefits of implementing knowledge management strategies have been proven but research has largely focused on technology as a solution. Working together with European-based telecommunication companies, we focus instead on the softer, human issues. The main human barriers identified include international differences, accuracy and protection of knowledge, maintenance of communication channels, lack of time, fear of penalties and market position.  相似文献

ABSTRACT

Drawing on the work of Rein and Schon (1993. “Reframing Policy Discourse.” In The Argumentative Turn in Policy Analysis and Planning, edited by F. Fischer, and J. Forester, 145–166. London: UCL Press., 1996. “Frame-Critical Policy Analysis and Frame-Reflective Policy Practice.” Knowledge and Policy: the International Journal of Knowledge Transfer and Utilization 9 (1): 85–104), we explore the ways in which ‘young people’, ‘vulnerability’, ‘risk’, ‘prevention’ and ‘prevention practice’ were defined and framed by practitioners engaged in the design, delivery and commissioning of drug prevention interventions for young people in contact with the criminal justice system. We argue that practitioners describe their work in terms of both a preventative frame – based on a ‘deficit’ model – and a transformative praxis frame, more in line with an increasing shift towards ‘positive youth justice’ where practitioners aspire to actively involve the young person in a process of change. The implications of those, often competing, frames are discussed in relation to the development of prevention approaches and the challenges in designing drugs prevention for this group of young people. The paper is based on interviews and focus groups with thirty-one practitioners in England and is part of the EU funded EPPIC project (Exchanging Prevention Practices on Polydrug Use among Youth in Criminal Justice Systems 2017–2020).  相似文献

The volume and variety of manufactured chemicals is increasing, although little is known about the risks associated with the frequency and extent of human exposure to most chemicals. The EPA and the recent signing of the Lautenberg Act have both signaled the need for high-throughput methods to characterize and screen chemicals based on exposure potential, such that more comprehensive toxicity research can be informed. Prior work of Mitchell et al. using multicriteria decision analysis tools to prioritize chemicals for further research is enhanced here, resulting in a high-level chemical prioritization tool for risk-based screening. Reliable exposure information is a key gap in currently available engineering analytics to support predictive environmental and health risk assessments. An elicitation with 32 experts informed relative prioritization of risks from chemical properties and human use factors, and the values for each chemical associated with each metric were approximated with data from EPA's CP_CAT database. Three different versions of the model were evaluated using distinct weight profiles, resulting in three different ranked chemical prioritizations with only a small degree of variation across weight profiles. Future work will aim to include greater input from human factors experts and better define qualitative metrics.  相似文献

An 8-week mindfulness-based cognitive therapy (MBCT) group for older adults with depression and/or anxiety is described. This article is based on an exploratory study of this therapeutic approach and changes in participants’ symptoms associated with participation. Pre-post data from 5 MBCT groups showed significant improvements in reported anxiety, ruminative thoughts, and sleep problems and a reduction in depressive symptoms. Case examples are presented to illustrate these symptom changes. Findings showed that this nonpharmacological intervention is acceptable to older adults and is associated with positive changes. Suggestions are provided for both practitioners and researchers interested in using MBCT with older adults.  相似文献
