武术散打比赛边裁判员评分结果公开显示的可行性研究

摘 要：对武术散打比赛边裁判员评分情况公开显示的可行性展开研究,有利于散打项目早日成为奥运会比赛项目在技术上做好准备。通过对比分析法、访谈法、问卷调查法和田野调查法等研究方法,研究认为：1)散打比赛采用“暗分制”,不符合体育比赛公开、透明的原则,有可能成为其进入奥运会赛场的障碍,应尽早进行改革。2)武术散打比赛实行“暗分制”有其客观原因和主观原因。3)在不影响边裁独立评判的情况下,武术散打比赛采用适当的方式公开显示边裁判员的评分情况不仅是必要的,也是可行的。

Accessibility,textbooks, and Access Services

Putting access in Access Services is the goal. The Course Reserves unit is the place. Textbooks are the focus. Electronic technologies are the future. Patron-centric services will be our standard. Access to textbooks by all patrons will be the achievement. Course Reserves located in Library West at the University of Florida George A. Smathers Libraries has begun policies and procedures to enhance the patron experience based on specific needs using programs, technologies, and particular attention to customer service. This article explores providing services for accessible electronic textbooks to patrons who have specific needs such as blindness or low vision.     

利用定位UAS-RNAi系统筛选果蝇运动抗心功能増龄衰退候选钙调控基因

目的:研究果蝇心肌细胞Ca2+调控相关基因敲减对増龄果蝇心脏功能及寿命的影响,筛选与心脏功能密切相关的Ca2+调控基因作为候选基因,为研究増龄果蝇基于Ca2+调控基因功能改变的心脏运动适应机制提供依据。方法:Hand-GAL4品系雄蝇、Ca2+调控相关基因UAS-RNAi品系雄蝇与野生型W1118处女蝇杂交,获得基因型为Hand/+和calcium regulation gene RNAi/+的F1代果蝇作为对照组果蝇;HandGAL4品系雄蝇与Ca2+调控相关基因UAS-RNAi品系处女蝇杂交,获得F1代基因型为Hand>calcium regulation gene RNAi的果蝇为心肌组织Ca2+调控基因RNAi组果蝇。采用M-mode方法对1周龄(约为人类青少年时期)和5周龄(约为人类中老年时期)成体果蝇心脏功能衰退相关FS、AI、FL等指标进行检测,并统计各组果蝇存活情况,制作存活曲线。结果:Ca MKII基因心肌敲减果蝇与对照组相比:存活率明显下降,1周龄时表现为FS下降显著,FL明显增高,5周龄时表现为DI,FS明显下降,SI,AI和FL显著上升;5周龄Ca-α1D基因心肌敲减果蝇对比同龄对照组,DI、SI明显降低,DD、SD明显增高;5周龄Anx B9基因敲减果蝇AI较同龄对照组显著上升。结论:Ca MKII基因在维持増龄果蝇心脏功能和寿命中发挥着重要作用,Ca MKII、Ca-α1D和Anx B9可作为候选基因研究増龄果蝇心脏功能运动适应的潜在机制。     

中超和欧洲五大联赛本国球员和外籍球员的身体形态特征比较研究

运用文献资料调研和数理统计等方法,对中超和五大联赛本国球员和外籍球员的年龄、身高、体重和克托莱指数进行比较分析。结论:在各国联赛球员中,中超本国球员的平均体重和克托莱指数排名末尾,身体对抗方面存在一定劣势。中超注重引入具有明显身体形态优势的外籍球员,但其年龄明显过高。各国联赛均倾向于选择体重和克托莱指数较大的外籍球员,表明体重和克托莱指数对联赛成绩存在一定影响。中超外籍球员比例过低,且各位置球员引进比例不合理,不利于各位置球员的均衡发展。建议中超参考五大联赛外籍球员的年龄和身体形态数据,根据自身实际情况,调整引进球员的标准、比例和结构;同时改进体能训练方式,解决本国球员体重和克托莱指数偏低的问题。     

训练年限、训练类型对大学生运动员心电图影响分析

摘要：目的 分析训练年限、训练类型对大学生运动员心电图 (electrocardiogram,ECG)的影响。方法 通过整群抽查,对840名竞技体育专业大学生入学体检时进行十二导联心电图检查并分析。结果 随着运动年限增加,大学生运动员正常心电图检出率下降（P<0.05）;大致正常心电图的检出率增加（P<0.05）。耐力型训练大学生正常心电图检出率低于力量型训练大学生（P<0.05）,大致正常心电图检出率高于力量型训练学生（P<0.05）。 窦性心动过缓、左室高电压、早复极、不完全右束支传导阻滞的发生率在训练年限长的运动员和耐力型训练的男运动员中发生率高（P<0.05）。异常心电图发生率和训练年限、训练类型无关。结论 窦缓、左室高电压、不完全右束支传导阻滞和早复极属于常见与训练相关的心电图改变;但ST-T改变、室内传导阻滞、完全性束支传导阻滞、早搏、预激综合征等属于不常见的与训练无关的心电图改变,遇到运动员心电图此类改变要进一步检查,排除潜在病理性心血管疾病。     

To be one’s own confessor: educational guidance and governmentality

Educational guidance is often seen as something good and empowering for the individual. In the present article, such taken‐for‐granted ideas will be destabilised by analysing educational guidance as a practice in which confession operates as a technology that fosters and governs specific subjectivities. White papers produced by the Swedish Ministry of Education will be analysed drawing on Foucault’s concepts of technologies of the self and governmentality. I shall argue that the practice of educational guidance fosters our will to learn through the technology of confession. We are not only confessing ourselves to, and are the confessors of others, we are also our own confessors; that is, we confess our inner desires to ourselves, thus participating in shaping desirable subjectivities. Our desires in life coincide with the political ambition to govern, and thus we govern ourselves.     

Data assemblages,sentient schools and digitised health and physical education (response to Gard)

Michael Gard raises some important issues in his opinion piece on digitised health and physical education (HPE) in the school setting. His piece represents the beginning of a more critical approach to the instrumental and solutionist perspectives that are currently offered on digitised HPE. Few commentators in education, health promotion or sports studies have begun to realise the extent to which digital data surveillance and analytics are now encroaching into many social institutions and settings and the ways in which actors and agencies in the digital knowledge economy are appropriating these data. Identifying what is happening and the implications for the concepts of selfhood, body and social relations, not to mention the more specific issues of privacy and the commercialisation and exploitation of personal data, requires much greater attention than these issues have previously received in the critical social research literature. While Gard has begun to do this in his article, there is much more to discuss. In this response, I present some discussion that seeks to provide a complementary commentary on the broader context in which digitised HPE is developing and manifesting. Whether or not one takes a position that is techno-utopian, dystopian or somewhere in between, I would argue that to fully understand the social, cultural and political resonances of digitised HPE, such contextualising is vital.     

欧洲体育模式的源流与发展对我国的启示

采用文献资料法对"欧洲体育模式"的发展历程进行了研究,通过对欧洲体育模式的研究为我国体育发展方式转变提供借鉴。研究表明,欧盟委员会于1999年提出"欧洲体育模式"概括了欧洲体育的结构和特征,但是包括欧盟和其它研究者都认为"欧洲体育模式"对于欧洲现行体育模式的概括存在着不足。欧洲体育模式多元化将欧盟各国的体育模式突破性地划分为官僚型、传教型、企业型和社会型四种类型,四种类型的体育模式各有其侧重和优劣,同时也都在相应地发生着改变。欧洲体育模式研究的启示在于,体育模式的多元化事实、动态化存在对于我国体育发展方式的促进和推动,以及体育模式比较的复杂性需要注意借鉴的审慎性。
