Pacing profiles and pack running at the IAAF World Half Marathon Championships     

Brian Hanley 《Journal of sports sciences》2015,33(11):1189-1195

The aim of this study was to describe the pacing profiles and packing behaviour of athletes competing in the IAAF World Half Marathon Championships. Finishing and split times were collated for 491 men and 347 women across six championships. The mean speeds for each intermediate 5 km and end 1.1 km segments were calculated, and athletes grouped according to finishing time. The best men and women largely maintained their split speeds between 5 km and 15 km, whereas slower athletes had decreased speeds from 5 km onwards. Athletes were also classified by the type of packing behaviour in which they engaged. Those who ran in packs throughout the race had smaller decreases in pace than those who did not, or who managed to do so only to 5 km. While some athletes’ reduced speeds from 15 to 20 km might have been caused by fatigue, it was also possibly a tactic to aid a fast finish that was particularly beneficial to medallists. Those athletes who ran with the same competitors throughout sped up most during the finish. Athletes are advised to identify rivals likely to have similar abilities and ambitions and run with them as part of their pre-race strategy.  相似文献   

Gender Verifications in Sport: From an East/West Antagonism to a North/South Antagonism     

Anaïs Bohuon 《国际体育史杂志》2015,32(7):965-979

This paper aims to analyze gender verifications in sport from a socio-historical approach. These medical controls intended to keep men from competing in women's international competitions. Some female athletes are put through a masculinization trial, because of morphologies and performances judged as too masculine. Facing these athletes who disrupt the representation of a binary construction between the male sex and the female sex, sports institutions attempt to maintain a sexual bi-categorization. More precisely, this paper will present the ‘symbolic’ suppression of tests since 2000. Thereafter, authorities only rely on an aesthetic and visual assessment of female bodies and no longer use tests in a systematic and obligatory fashion. This reveals the moving boundary subjectively plotted between the masculine and the feminine, which become all the more blurred when the ‘race and class markers’ interfere with the ‘sex markers’.  相似文献

美国作家罗斯《人性的污点》“身份情节”评析     

宋继红 《辽宁师范大学学报(社会科学版)》2015,(2):239-243

菲利普·罗斯是美国著名犹太小说作家,《人性的污点》是其美国三部曲的最后一部。罗斯在这部小说中遵循并超越了他称之为"身份情节"的体裁。这部小说通过各种方式将种族身份解释为种类、符号或生物学特征,最终揭示了主人公科尔曼种族身份的最具有决定性作用的特征就是他的隐秘性。对于罗斯来说,秘密不仅是身份的来源,也是欲望和叙述的驱动力。《人性的污点》不仅仅通过种族身份的掩藏与揭露探究了种族问题,也揭示了人性的很多污点,譬如婚外恋、乱伦等。但小说所有的辅助线索都是为了服务、突出种族问题这个大前提,背景的叙述也是为了给科尔曼和弗妮娅的恋情铺平道路。  相似文献   

Advanced Math Course Taking: Effects on Math Achievement and College Enrollment     

Soo-yong Byun  Matthew J. Irvin  Bethany A. Bell 《Journal of Experimental Education》2015,83(4):439-468

Using data from the Educational Longitudinal Study of 2002–2006, the authors investigated the effects of advanced math course taking on math achievement and college enrollment and how such effects varied by socioeconomic status and race/ethnicity. Results from propensity score matching and sensitivity analyses showed that advanced math course taking had positive effects on math achievement and college enrollment. Results also demonstrated that the effect of advanced math course taking on math achievement was greater for low socioeconomic status students than for high socioeconomic status students, but smaller for Black students than for White students. No interaction effects were found for college enrollment. Limitations, policy implications, and future research directions are discussed.  相似文献

Autism and intersectionality: Considerations for school-based practitioners     

Kari A. Sassu  Fred R. Volkmar 《Psychology in the schools》2023,60(2):408-418

The purpose of this article is to explore the intersectionality of autism and sociocultural factors as well as discuss the complexities associated with appropriate assessment, diagnosis, and intervention. Based on a review of the literature, the authors present a brief history of the emergence of the term autism and highlight factors that have contributed to current concerns about failures to appropriately recognize autism within diverse populations. Referencing extant research as well as professional practice standards, this article examines aspects of autism and intersectionality, and explores some of the associated challenges related to assessment, diagnosis, and intervention. Further, the authors reflect on the critical importance of carefully considering all aspects of a child's identity when engaging in autism assessment and intervention within the school setting. School-based practitioners are provided with guidance for addressing the needs of diverse populations of students with autism.  相似文献
