Abstract

Though it is generally acknowledged that there is a relationship between racist discourse and the figure of the non-human animal, this relationship is almost always assumed to be analogical: oppressed groups are compared with or treated as non-human animals. But the recent dogfighting case against NFL Quarterback Michael Vick and the attendant suspicion of ‘pit bulls’ suggests that racism today has a more complex relationship with (certain types of) animals than the analogy would capture. An analysis of this discourse both calls for and revises Foucault's notion of ‘the dangerous individual’ as an explanatory concept for contemporary racism. The concomitant revulsion toward both dogfighting and ‘pit bulls’ suggests an expression of fear of a perceived threat to normative whiteness, insofar as these ‘dangerous’ dogs are figured as carriers of the contagion of racial abnormality.  相似文献

A notational analysis of singles events at all four Grand Slam tournaments between 1997 and 1999 was conducted to determine the influence of the sex of the player and court surface on elite tennis strategy. Rallies of 7.1 ± 2.0 s in women's singles were significantly longer than those in men's singles (5.2 ± 1.8 s P < 0.001). Rallies of 6.3 ± 1.8 s at the Australian Open, 7.7 ± 1.7 s at the French Open, 4.3 ± 1.6 s at Wimbledon and 5.8 ± 1.9 s at the US Open were recorded. Rallies were significantly longer at the French Open than at any other tournament ( P < 0.05) and significantly shorter at Wimbledon than at any other tournament ( P < 0.05). In women's singles, 52.8 ± 12.4% of points were baseline rallies, significantly more than in men's singles (28.6 ± 19% P < 0.001). The proportion of baseline rallies played at the French Open (51.9 ± 14.2% of points) was significantly greater than at the Australian Open (46.6 ± 12.5%), Wimbledon (19.7 ± 19.4%) and the US Open (35.4 ± 19.5% P < 0.05). The results show that both the sex of the player and surface of the court have a significant influence on the nature of singles tennis at Grand Slam tournaments.  相似文献

Despite the clear relationship between physical activity and quality of life, few sound, relevant quality of life measures exist. Gill and colleagues developed a 32-item quality of life survey, and provided initial psychometric evidence. This study further examined that quality of life survey in comparison with the widely used short form (SF-36) health survey. Participants (n = 446) completed the quality of life survey, short form (36) health survey, World Health Organization quality of life measure, satisfaction with life scale, and the Godin physical activity measure. All quality of life survey scales (emotional, social, spiritual, physical, activities of daily living, cognitive, integrated) were internally consistent (alpha .79–.95) and test–retest correlations ranged from .68 to .82. The SF-36 had similar internal consistency, slightly lower test–retest correlations, and weaker relationships with satisfaction with life scale. Quality of life survey scales correlated with matching SF-36 and World Health Organization quality of life measure subscales supporting convergent validity. The quality of life survey reflects positive health models better than the SF-36, and is more appropriate for research and programs that focus on physical activity and health promotion.  相似文献

Sprinting while towing a sled improves sprinting parameters, however, only kinematic and temporal–spatial variables have been reported. The purpose of this study was to determine how lower extremity joint moment impulses alter when towing a sled compared to normal walking. Twelve participants walked normally, walked while towing a sled with a 50% body weight load attached at the waist, and with a 50% body weight load attached at the shoulders. Joint moment impulses were calculated for the hip, knee, and ankle. A mixed-model ANOVA with a between-subject factor of limb and repeated measures of condition was used to compare differences between limbs and towing conditions for each joint. Towing a sled increased joint moment impulses at the hip, knee, and non-dominant ankle. When compared with normal walking waist attachment increased hip extension moment impulse by 214.5% ( ? 3.31 vs. ? 10.41 Nms/kg), and shoulder attachment increased knee extension moment impulse by 166.9% (4.62 vs. 12.33 Nms/kg). The dominant limb produced greater knee extension moment impulse (p < 0.001), while the non-dominant limb produced greater hip extension (p < 0.001) and ankle plantarflexion moment impulse (p < 0.001) across all conditions. Results suggest that walking while towing may increase hip and knee extension strength.  相似文献

Abused children experience high rates of behavior, emotional, and learning problems but infrequently receive treatment. Most services provided to abused children and their families are not based on any clear evidence that they work. A number of evidence‐based treatments (EBTs), demonstrated to be safe and effective in treating a range of difficulties that present in children exposed to family violence, are appropriate for schools. We briefly review forms of abuse, describe EBTs appropriate for schools, and present a decision tree for deciding who to treat and how. © 2009 Wiley Periodicals, Inc.  相似文献

Articles published between 2000 and 2008 in four major school psychology journals—School Psychology Review, Journal of School Psychology, Psychology in the Schools, and School Psychology Quarterly—were classified based on type (empirical or narrative) and on the primary and secondary authors' affiliations. Results showed that more than 90% of the primary and secondary authors were university affiliated with little difference across article type. Although more than 85% of school psychologists are practitioners, these results suggest that their contributions to these school psychology journals are limited because they account for less than 10% of the authors of articles. Discussion focuses on practitioners' involvement in the research base that is intended to inform their professional behaviors. © 2009 Wiley Periodicals, Inc.  相似文献

This article contributes to the theory of institutional habitus by exploring the differing ways in which the institutional habitus of two schools in Belfast, Northern Ireland mediates the local habitus of working‐class boys. All of the boys in this qualitative case study live in the same disadvantaged working‐class community but attend two different schools, depending on whether they succeeded or failed in an examination at the age of 11 years. It is argued that these schools have different mediating effects on the boys’ common habitus. While most studies of working‐class boys focus on underachievement, and most studies of working‐class success focus on females, this article draws together the strands of success, failure, working‐class boys and locality, and examines the ways in which identity is constructed and reconstructed in response to schooling. Questions are raised about the interpretation and/or misrecognition of working‐class culture in schools and within the wider discourses of society.  相似文献

Abstract Zoos aspire to be leaders in environmental conservation through their work in environmental education. This study examined whether a spokesperson's job title impacts credibility when conservation messages are delivered to the public. Visitors to a zoo were presented with seven environmental messages. They then selected—from a list of zoo‐related job titles—the one they deemed most credible and the one considered least credible. Statistical analysis established that three “credible” job titles were selected significantly more often, while three were generally selected as “least credible.” The authors demonstrate that some job titles have greater credibility than others among visitors, and recommend that more attention be given to this variable if attitude and behavior change are desired outcomes. They caution that while source credibility may vary based on job title, the influence it has on persuasiveness is yet to be determined.  相似文献
