法治视角下我国运动员参赛资格管理的改革与创新     

王家宏  辜德宏 《成都体育学院学报》2020,(2):11-19

文章运用文献资料法对我国运动员参赛资格存在的典型问题及特点、运动员参赛资格改革的困境进行了分析,在此基础上借鉴权利保障、公平竞争、程序正义原则,提出了我国运动员参赛资格管理改革的几点建议。研究认为:我国运动员参赛资格存在的典型问题为,尖子运动员无法获得参赛资格、运动员的竞争优势被蓄意改变、运动员参赛行为遭受人为干扰;其特点主要表现为,问题主要集中发生在我国的传统优势项目,运动员处于弱势被支配地位,运动员较难争取应得权益。改革的困境主要在于,管理机构设置方面,选拔主体与审批主体同构,权力缺乏制约;管理理念方面,国家利益或集体利益高于一切,个人利益有时成为牺牲品;管理流程方面,自由裁量空间大,选拔程序尚待规范;管理手段方面,监督和约束手段相对单一,管理亟需优化。研究建议:逐步做实项目协会和奥委会,体育行政部门负责监督、审计和政治审查;严禁参赛资格的利益交换,以法治代人治,保障运动员的合理权益;建构规范的管理流程,明晰选拔标准、程序及选拔主体权限,提升管理效能;完善内部救济机制,司法适度介入,提升运动员参赛资格的权利保障和救济水平。  相似文献   

基于ICWGT和灰色关联分析法的起重机安全评价     

肖汉斌  熊楚宸  祝锋  刘敏 《上海海事大学学报》2020,41(2):117-122

针对目前起重机安全评价过于依赖主观权重且忽视起重机安全状态变化趋势的问题，建立基于改进博弈论组合赋权法（improved combination weighting method of game theory，ICWGT）和灰色关联分析法的起重机安全评价体系。在该评价体系中，收集样本数据以确定评价值，构建评价等级空间来计算起重机行为特征序列与标准行为特征序列的关联系数。运用ICWGT在层次分析法和信息熵 未确知测度理论确定的主、客观权重中寻找平衡。充分考虑专家经验和样本数据，确定优化权重以改善关联系数的分配问题，从而获取起重机灰色关联度评价值和安全等级，旨在对起重机安全状态变化趋势进行更加准确的定量描述和定性分析。实例分析验证了该评价体系的有效性。  相似文献   

Where are we now? A review of research on the history of women's soccer in Ireland     

Helena Byrne 《Sport in History》2019,39(2):166-186

ABSTRACT

It is a common fact that women's sport and leisure history, especially in male dominated spheres, and more specifically football, have been ignored by many academics. However, in recent years there have been major developments in digital technology that have changed the nature of the type of research that can be done. Access to tools to facilitate field research are relatively cheap and with the high volume of digitisation projects that have taken place over the last few years as well as the increasing number of born digital resources that have been published, there are new opportunities. In relation to women's soccer in Ireland, this paper asks the question – where are we now? The argument will review the current literature on this subject and outline potential approaches for future research.  相似文献

Evaluation of soccer players under the Moneyball concept     

Luiz Octávio Gavião  Annibal Parracho Sant’Anna  Gilson Brito Alves Lima  Pauli Adriano de Almada Garcia 《Journal of sports sciences》2020,38(11-12):1221-1247

ABSTRACT

The recruitment of athletes with limited resources is a global problem in professional sports. In US Major League Baseball, the experience of the Oakland Athletics’ general manager in the last decade turned his “Moneyball” model into a synonym of quantitative analysis in the transfer market of baseball players. His strategy focused on hiring players with outstanding technical skills but relatively low market value. This study adapted this model to the framework of a multiple criteria decision aid (MCDA), by selecting undervalued players who have complementary abilities. The novelty here refers to the joint use of four algorithms explored by the composition of probabilistic preferences (CPP) (i.e., ranking, classification, dynamic evaluation and regularity analysis) and their application to soccer player performance evaluation. The new model analysed the recent transfer of a left-back soccer player to Europe. The results indicated 12 opportunities for better investment, among 32 left and right-back players considered. Two years later, the value of the same player was considerably lower. He played only five matches in the 2018–2019 season, without scoring or providing any assists. On the other hand, the players better classified by the CPP-MB model presented higher performances and market values.  相似文献

传播的游戏理论视角下 新浪微博俄罗斯世界杯传播效果分析          下载免费PDF全文

陈肖鹏 《河北体育学院学报》2019,33(3):33-38

使用“传播的游戏理论”，对新浪微博俄罗斯世界杯传播效果进行分析，并对新媒体用户的需求进行探讨。研究认为，世界杯传播是一场盈余时代的足球“游戏”，满足用户对愉悦、趣味的需求和对游戏的需求是新媒体未来发展的一种趋势；新浪微博俄罗斯世界杯期间，体现主观、个性的“选择性会聚”让用户在“游戏”过程中促进了“自我”的发展；只为享受足球魅力的非功利性传播为用户提供了一个宽松的“游戏”环境；利用微博话题、短视频、直播等新媒体技术传播乐趣，用户从“游戏”中收获了愉悦。对于传播效果的研究立足受众的个性特征和主观心态，注重体现个体主观能动意识，对把握未来新媒体传播发展和趋势具有启示意义。  相似文献   

The effects of a calf pump device on second half performance of a simulated soccer match in competitive youth players     

S. Béliard  J. Cassirame  G. Ennequin  G. Coratella  N. Tordi 《Journal of sports sciences》2019,37(6):708-716

During soccer matches, performance decrements have been reported that relate to both physical abilities and technical skills. To investigate the effects of low-frequency electrical stimulation LFES (VeinoplusSport®, Ad Rem Technology, France) administered during half-time recovery on performance alterations during the second half. Twenty-two highly trained young players undertook a soccer-match simulation (SAFT⁹⁰). During half-time, they were randomly assigned to LFES group or Placebo group. Each half was split into 3 bouts of 12 minutes. Following each bout, maximal strike speed (MSS), sprint test (ST), maximal sprint accelerations (MA) and metabolic power (MP) were determined in both groups. Arterial (AF) and venous flows (VF) were measured at rest and at the end of half-time. LEFS group exhibited beneficial effects on performance compared to the Placebo group with a likely effect for MSS, ST, MA, and a possible effect for MP. AF and VF increased statistically more in LEFS group compared to Placebo group. The use of specific calf-pump LFES during half-time of a youth simulated soccer match attenuated the decrease in performance during the second half compared to Placebo group. This effect is most marked at the beginning of the second half with regards to explosive parameters.  相似文献   

运动与褪黑素抗抑郁的作用、机制以及联合策略研究进展     

黄卓淳  漆正堂  刘微娜 《中国体育科技》2020,(2):3-14

褪黑素(melatonin,MT)在同步昼夜节律方面具有关键作用,且抑郁症的主要特征就是昼夜节律紊乱导致的睡眠障碍和褪黑素分泌紊乱。针对昼夜节律系统开发出的褪黑素类似物(如阿戈美拉汀、雷美替胺、他司美琼等)在治疗抑郁症方面有积极作用,特别是阿戈美拉汀,这是一种具有抗抑郁和抗焦虑作用的褪黑素受体激动剂及5-HT2C受体拮抗剂。研究综述了昼夜节律紊乱与抑郁症之间的关联,以及褪黑素在运动调控生物节律与改善抑郁行为方面的作用及机制,并提出了运动联合MT的抗抑郁策略。提出运动的抗抑郁作用,一方面通过MT的分泌调节使生物节律同步和MT促进海马神经发生和生物钟基因表达同步,另一方面通过MT调节脑源性神经营养因子节律和水平及改善炎症和氧化应激。  相似文献
