ABSTRACT

Recently, there has been much controversy over the International Association of Athletics Federation (IAAF) regulations regarding eligibility to compete and natural testosterone levels in female athletes. Much interest lies in the analysis of Caster Semenya's extraordinary performance. The objective of this work were, a) Complete an analysis of Caster Semenya's results during the 800m finals and b) search for existing similar performances by other female athletes. We analysed the results of the finals of all IAAF World Championships and Olympic Games from 1984–2016, including the 800m results of the Diamond Leagues 2016–2018. Exponential curves were fit to the data to characterise and predict performance for each event. Caster Semenya's finishing times before her ineligibility to compete and after the suspension of the IAAF hyperandrogenism regulation were found to be 1.24% and 1.49%, respectively, faster than the characteristic performance of the elite-standard in the women’s 800m final. Other female athletes, with finishing times faster than the ones predicted by the characteristic curves were also discovered. The percentage difference in performance between Caster Semenya and the other participants did not reach 3% in the 800m event. No conclusions can be drawn regarding extraordinary results ever performed during the 100m, 200m or 400m finals.  相似文献   

田径表演赛可行性探析     

崔永衡 《体育科技文献通报》2015,(1)

随着科技水平的发展，电视、多媒体网络等各种传播媒介的迅速发展，体育产业的迅速崛起，人们生活质量的提高、财富的积累，使得人们对体育的诉求也在不断的发生着变化。各种体育赛事逐步融入了表演赛，来扩大本项运动的国际影响力。由于体育明星效应，使得一些体育运动在国内一度掀起过高潮。那么，我们可以借鉴这种市场化的操作方式，从宏观的角度论述田径表演赛，通过明星效应，结合市场管理的方法，提升对田径运动兴趣，加大对田径运动知识的了解、认识，从而起到缓解瓶颈期学校体育中田径常年不受学生青睐的尴尬局面，迎来田径发展新“春天”。  相似文献

试论高校学报的变革与编辑素质     

课题组 《河北师范大学学报(哲学社会科学版)》2001,24(2):141-144

高校学报作为学术交流、技术推广、信息服务的渠道，对推动我国教育事业及学术事业的发展起到了不可低估的作用。但随着市经济体制的逐步建立及各级高校的全方位变革，高校学报也面临着除弊革新的现实，其中，正确定位、办出特色及改变传统办刊模式中存在的弊端应成为高校学报变革的两个重要方面。同时，高校学报的变革对作为学报主体的编辑素质也提出了全新的要求。  相似文献   

The moderating role of cultural orientation in explaining temporal orientation of self-referencing     

Seungae Lee  Jun Heo 《亚洲交流杂志》2016,26(4):333-349

A psychological process called self-referencing justifies the use of ‘you’ statements in advertisements; the more an individual relates an ad to him/herself, the greater the likelihood of recall and favorable evaluation. Self-referencing can be differentiated based on the temporal dimension of the self being activated while processing advertisements: when people remember themselves in the past they engage in retrospective self-referencing whereas they engage in anticipatory self-referencing when imagining themselves in the future. The current study examined the moderating role of consumers’ cultural background (i.e. long-term vs. short-term orientation) on the effects of temporal orientation of self-referencing. A corollary of this premise is that the match between cultural time orientation and the type of self-referencing activated by an ad will increase the extent of viewers’ self-referencing as well as advertising effectiveness. Further, this study confirmed a mediating role of self-referencing in explaining the match effects. The findings inform the extant literature on self-referencing and also provide managerial implications for international advertising practitioners.  相似文献
