It is the argument of this paper that the literature on mid-century racial discrimination in sport is incomplete in that it ignores the experiences of a small, but relatively significant, group of African-American football players who actually chose to leave their own country – and correspondingly leave the racially-charged environment of mid-twentieth-century USA – to head north to play professional football in the Canadian Football League (CFL). Beginning in 1946, a steady flow of African-Americans began to migrate to the CFL which, at the time, was a legitimate competitor league to the NFL. This paper attempts to test a perception seemingly held by some that, by moving to Canada, African-American football players were able to escape the racial injustices they often suffered in the US. This view appears to have its roots in the notion that Canada is a ‘gentler’, more tolerant society, without the divisive socio-political history that characterizes much of the race relations in the US. This paper tests these notions using a variety of empirical approaches. The results indicate that, while African-Americans were better represented in the CFL relative to the NFL, African-Americans still faced some level of entry discrimination in the CFL. In particular, African-American players in the CFL outperformed their white counterparts on numerous performance dimensions, indicating the overall talent level in the CFL could have been further improved by employing an even greater number of African-Americans. Additionally, the paper finds that those CFL teams that employed the highest percentage of African-Americans were those teams that had the most on-field success. Finally, the paper analyses prices of player trading cards from that era, and finds that cards of African-Americans were undervalued, relative to white CFL players of equal talent. 相似文献

AbstractThis study analysed the first stance phase joint kinetics of three elite sprinters to improve the understanding of technique and investigate how individual differences in technique could influence the resulting levels of performance. Force (1000 Hz) and video (200 Hz) data were collected and resultant moments, power and work at the stance leg metatarsal-phalangeal (MTP), ankle, knee and hip joints were calculated. The MTP and ankle joints both exhibited resultant plantarflexor moments throughout stance. Whilst the ankle joint generated up to four times more energy than it absorbed, the MTP joint was primarily an energy absorber. Knee extensor resultant moments and power were produced throughout the majority of stance, and the best-performing sprinter generated double and four times the amount of knee joint energy compared to the other two sprinters. The hip joint extended throughout stance. Positive hip extensor energy was generated during early stance before energy was absorbed at the hip as the resultant moment became flexor-dominant towards toe-off. The generation of energy at the ankle appears to be of greater importance than in later phases of a sprint, whilst knee joint energy generation may be vital for early acceleration and is potentially facilitated by favourable kinematics at touchdown. 相似文献

Government support for the production and consumption of educational software is now a key element of New Labour's education technology drive. At present much attention is being directed towards marketing ‘digital learning’ to an educational sector traditionally wary of technological innovation. In an effort to understand the social shaping of this current phase of policy‐making, the present paper examines the political and commercial discourses surrounding digital learning and associated initiatives such as Curriculum Online and the Digital Curriculum. After analysing a range of political and commercial texts produced from 2000 to 2005, the paper explores the dominant themes emerging from these discursive constructions—considering in particular the limitations of the often ambiguous yet structured ways in which digital learning is being shaped by its key actors. 相似文献

Comparative studies of attitudes in different countries have resulted in the claim that parents in the USA and England tend to have unrealistically positive views of their children's schools and academic performance. Low expectations, together with a belief in the importance of natural ability, it has been argued, lead to low standards and reduce striving to succeed. The present study builds upon earlier investigations of children's attitudes, beliefs and behaviours in Sunderland, Eastern Kentucky and St Petersburg by surveying parental perspectives. Findings from these three regions reinforce earlier findings about English and American complacency and the more demanding nature of the Russian context. In line with our earlier studies, and contrary to the suggestion of a number of writers, an emphasis upon effort, rather than ability, was a strong feature of the English and American responses, although it is pointed out that such beliefs may not actually result in high work rates. The paper concludes by suggesting that the important role of parents in instilling important attitudes and behaviours in their children is undermined by the current emphasis upon schools as fundamentally responsible for ensuring high levels of achievement. 相似文献

In the field of conservation, the distinction between academic research and advocacy appears to be undergoing a shift as the number of PhD-level researchers at conservation advocacy organizations grows. Drawing on my case study of one researcher at a prominent conservation nongovernmental organization (NGO), I have shown how this shift is manifested in the communication of NGO research. My study includes a discourse analysis of this researcher's publications from the forums of both scholarship and advocacy including, as a representation of discourse in the latter forum, gray literature (reports, books, and other texts produced and distributed outside the channels of the academic and publishing industry). I have also drawn on my interviews with this researcher about her publications. My study highlights specific features typical of her rhetoric that result from her occupying a hybridized cultural and professional space where research and advocacy overlap. 相似文献
