AbstractThough 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

Alternating current (AC) dielectrophoresis (DEP) experiments for biological particles in microdevices are typically done at a fixed frequency. Reconstructing the DEP response curve from static frequency experiments is laborious, but essential to ascertain differences in dielectric properties of biological particles. Our lab explored the concept of sweeping the frequency as a function of time to rapidly determine the DEP response curve from fewer experiments. For the purpose of determining an ideal sweep rate, homogeneous 6.08 μm polystyrene (PS) beads were used as a model system. Translatability of the sweep rate approach to ∼7 μm red blood cells (RBC) was then verified. An Au/Ti quadrapole electrode microfluidic device was used to separately subject particles and cells to 10Vpp AC electric fields at frequencies ranging from 0.010 to 2.0 MHz over sweep rates from 0.00080 to 0.17 MHz/s. PS beads exhibited negative DEP assembly over the frequencies explored due to Maxwell-Wagner interfacial polarizations. Results demonstrate that frequency sweep rates must be slower than particle polarization timescales to achieve reliable incremental polarizations; sweep rates near 0.00080 MHz/s yielded DEP behaviors very consistent with static frequency DEP responses for both PS beads and RBCs. 相似文献

Historians know that any mention of football and World War I will involve discussions of the Christmas truces of 1914 and the mythical football match between British and German troops. Many British soldiers denied that any truce had occurred let alone a football match. However, while there is indisputable evidence of truces, triangulating proof of football has been elusive. In this paper, a case study of the British 2/Argylls and the German 133/Saxons is developed. The underlying reasons behind the truce are discussed and why some combatants, in the short break from trying to kill each other, probably played football, even though certainly not as the formal match of popular imagination. It is argued that the truce was a result of unique circumstances and was not an overwhelmingly inspirational moment for the majority of troops involved; they all returned to the fighting. Most participants on both sides of the truce probably regarded it as an unexpected holiday and some availed themselves of the opportunity to play their favourite game. The paper concludes by examining recent commemorative events of Christmas 1914 and how they may have contributed to the myth of ‘The Football Match’. 相似文献

Abstract Opportunities for ball passing in water-polo may be brief and the decision to pass only informed by minimal visual input. Since researchers using point light displays have shown that the walking or running gait of familiars can be identified, water-polo players may have the ability to recognize team-mates from their swimming gait. To test this hypothesis, members of a water-polo team and a competition swim team viewed two randomized sets of video clips, each less than one second long, of swimmers from both teams sprinting freestyle past a fixed camera. The arm stroke clip sequence showed only the upper body, and the kick sequence showed only the lower body. After viewing each video clip, observers rated their level of certainty as to whether the swimmer presented was a team-mate or not. Discrimination was significantly above chance in both groups. Water-polo players were better able to identify team-mates from their kick, whereas swimmers were better able to do so by viewing arm stroke. Our results suggest that, as with walking and running gait, small amounts of visual information about swimmers can be used for recognition, and so raise the possibility that specific training may be able to improve team-mate classification in water-polo, particularly in newly formed teams. 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

This small‐scale study details the development and execution of a system of inclusive education in 20th and 21st century in Poland. A detailed review of the literature and employment of in‐depth semi‐structured interviews aimed to establish how inclusion is defined and operationalised in Poland. In addition, the study sought to establish how the teachers' levels of professional development and personal attitudes towards inclusion were influencing the evolution of this important educational initiative. The data from the study detail that the concept of inclusion is not well known in Poland, and that integrative education still dominates educational thinking. The study provides data to suggest integration in Poland works well in the early stages of education, but that it struggles to provide for and integrate older children into the mainstream educational settings. The research concludes that Poland has taken an important but perhaps faltering step towards educating all children in the mainstream schools. 相似文献

This paper details the findings from a study of airline compliance with Department of Transportation (DOT) regulations requiring that persons with disabilities not be discriminated against in the pricing of airline travel. These regulations mandate that if an airline website is inaccessible for persons with disabilities, the airline must charge the same price that is available on the website and may not charge a fee for purchasing tickets over the phone. To evaluate compliance, the websites of leading airlines were examined for accessibility in terms of the ability to check flight schedules and order tickets. Among the four airlines with barriers to accessibility on their websites, a series of phone calls were made by researchers to assess whether the DOT regulations would be followed. Two of the airlines, USAirways and United, practiced discriminatory pricing, even after being made aware of the regulations, in over one-third of the phone calls. This paper details the findings from the study and analyzes the data in terms of website accessibility, civil rights for travelers with disabilities, and policy implications. 相似文献
