通过对比分析在2017年世界男排联赛上中国男排与对手在比赛中的整体技术效果、3站比赛间中国男排自身的技术效果及各站对手的技术效果，得出在劳尔教练任期的第一次世界大赛中国男排技术效果上的优势与不足，为其日后训练比赛提供数据参考和建议。研究发现：中国男排在发球、一传和防守技术效果上显著差于对手，一攻和反攻技术效果略差于对手，仅拦网技术效果显著好于对手。发现中国男排存在如下问题：（1）发球技术能力与外教战术意图不匹配，且缺少沟通；（2）一传稳定性差，顶不住大力发球冲击成为被对手制约的短板，且一传的差距直接转化为一攻的差距表现出来；（3）二传传平拉开球速度不够快，导致战术进攻意图过于明显；（4）比赛中拦网技术存在补拦意识仍不够、移动跟不上、拦一点放弃了两点的不足；（5）防守队员预判能力不够，下蹲过浅造成移动慢，从而对拦起球的保护跟不上。此外，研究还就3站比赛进行分类对比分析，得出了相应结论与建议。  相似文献   

Association between psychosocial stressors with emotional and behavioral problems among children of low-income addicted families living in Brazil     

《Child abuse & neglect》2019

BackgroundChildren exposed to substance use in their families are vulnerable to multiple risk factors in their development and at increased risk for emotional and behavioral problems. The aims of the study were as follows 1) estimate the prevalence of emotional and behavioral problems among children aged 6–11 years old, living with addicted family members in a low-income urban community of São Paulo, Southeastern Brazil; 2) evaluate the children’s exposure to family psychosocial stressors and substance use; and 3) investigate the factors related to the increased risk of emotional and behavioral problems and substance use.MethodsA cross-sectional study was conducted among 101 children aged 6–11 years old (M = 9.16 years, SD = 1.61). The instruments used were a sociodemographic questionnaire, the Child Behavior Checklist (CBCL) and the Psychosocial Stress Factors (PSF).ResultsHigh prevalence of problems was found for this sample: the CBCL showed 26.7% of clinical scores for Internalizing Problems, 40.6% for Externalizing Problems, and 40.6% for Total Problems. Exposure to family psychosocial stressors was also high, including severe disease (33%), physical aggression (28.9%), death (27.8%), psychiatric hospitalization (16.7%), suicide attempts (15.5%), and suicide (9.3%). Exposure to these family stressors was associated with an increase of two to four times in the prevalence of internalizing and externalizing problems.ConclusionsChildren exposed to substance abusers have more mental health problems than general population, even when compared to peers living in similar low-income areas. This is a group that should be target of a selective preventive intervention.  相似文献   

基于法治的自治——后脱钩时代全国单项体育协会改革的思考     

刘苏  汤卫东  许兰 《武汉体育学院学报》2019,53(8):50

后脱钩时代，全国单项体育协会坚持依法自治不仅是"依法治体"的基本要求，而且也是脱钩改革有效落实的基本保证。针对全国单项体育协会存在的自治权性质界定不统一、非营利性属性规定不明确、体育行政权力异化、内部法人治理机制不健全的法治困境，从实体和程序上两方面来保障实现全国单项体育协会自治的法治化，以便真正实现单项协会的实体化，具体提出了单项协会自治主体性质的明确、相关法律规定的完善、非营利性标准的明晰界定等措施。  相似文献

船舶靠泊过程中系缆作业仿真     

代广树 《上海海事大学学报》2019,40(4):17-21

为更加准确直观地模拟船舶靠泊过程中的系缆作业,将缆绳分为两部分进行建模。对缆机滚筒上的缆绳提出缠绕算法模型,计算出缆绳随着滚筒旋转的收放速度,实现使用滚筒收放缆绳的模拟。对缆机滚筒外的缆绳建立悬链线模型,计算出缆绳在不同工况下的形状和端点处的受力情况,并根据计算出的缆绳张力是否超出安全负荷对缆绳进行破断分析。根据船舶和码头形状确定碰撞检测区域,采用基于距离场的碰撞检测方法实现缆绳与船体、缆绳与码头之间的碰撞检测。通过模拟缆绳在系缆作业过程中的形状、位置和姿态变化,实现船舶靠泊过程中系缆作业的三维可视化。  相似文献   

关于我国引入足球职业裁判制度的思考          下载免费PDF全文

何博芳 《河北体育学院学报》2019,33(4):24-28

职业裁判制度是足球职业化发展到一定阶段的必然产物，其引入将有力提升我国裁判执法水平，助推我国足球事业发展。认为，职业裁判是职业联赛健康发展的关键力量，是足球运动技术发展的客观要求，是提升足球裁判整体水平、统一集中管理的需要。目前，我国的足球裁判存在基数小、水平低、待遇低、环境差等问题。只引入足球职业裁判制度而无配套措施，可能无法解决根本矛盾；目前的国内联赛规模也还无法满足职业裁判发展需求，职业转换难度大及退休保障不足，也阻碍着我国职业足球裁判制度的实施。指出，应加快足球联赛发展，与职业裁判发展互促互进；健全体育裁判法律法规，改革职业裁判组织管理方式；建立健全职业裁判员的薪酬和退休保障体系；注重青少年裁判培养，全面提升在职裁判员业务水平。多管齐下，使足球职业裁判制度发挥更好的效果。  相似文献   

Embodied inter-referencing: encounters with and among “Asian” students in the Australian classroom     

Jane Chi Hyun Park 《Inter-Asia Cultural Studies》2019,20(2):271-289

ABSTRACT

This essay examines the pedagogical practice of referencing my experiences as a transnational Korean American woman in the classroom and considers how it opens up space for domestic and international students of East, Southeast, and South Asian backgrounds to reflect on their different identities, histories, and cultures. In particular, it focuses on how this practice enables Asian students to share their experiences of and insights about racial difference, racism, and whiteness in Australia and other parts of the world. Building on the concept of Asian “inter-referencing” from Chua Beng Huat (2015), I coin the term “embodied inter-referencing” to describe the strategic ways I use autobiographical narrative to create an inclusive, interactive, and mutually respectful learning space. I centre here on how some Asian students respond to this strategy by telling their own stories and in the process, create transnational, diasporic, and inter-Asian affective communities inside and outside the classroom.  相似文献   

Between business and morality: cultural politics in independent bookshops in China     

Zheng Liu 《Journal of Cultural Economy》2020,13(4):461-474

ABSTRACT

This article investigates how cultural businesses may facilitate contentious political activity in authoritarian contexts. Existing research in Western liberal democracies has shown the widespread political activism of actors in the cultural and creative industries. Whether such activism exists in authoritarian society, how it may differ in character and form, and what implications this will have for our understanding of relations between business, politics, and culture in authoritarian countries remain to be addressed. Drawing on data collected from 55 ‘independent bookshops’ in China, I illustrate how these organisations perform ‘cultural politics,’ a type of political participation in which actors employ mainly symbolic means to express social and political concerns. The organisations’ economic relations and conditions facilitate their efforts to create spaces in which contentious questions can be raised, sensitive topics explored, and alternative ideas expressed, despite the Chinese state’s political regulation of the cultural sphere. The finding of the economic embeddedness of cultural politics sheds new light on our understanding of the political economy of cultural businesses in contemporary China.  相似文献

中美竞技体育国际竞争力比较研究     

朱玉霞 《河北体育学院学报》2020,34(1):37-42

运用双框架模型对中美竞技体育国际竞争力进行比较研究。认为:①从显现性框架分析,美国竞技体育国际竞争力一直稳定处于高位,而中国则呈现以2008年为峰顶的倒“U”型发展特征,且与美国还存在一定差距;②从解释性框架分析,美国竞技体育国际竞争力已趋于顶峰,而中国稳步提升;③中国竞技体育发展潜力巨大,但短时间内难以赶超美国;④“举国体制”有利于中国竞技体育显现性竞争力的提升,但与美国社会办竞技体育的发展模式相比,市场、社会在竞技体育发展中的作用发挥不足,不利于高经济性项目、高欣赏性项目的发展;⑤坚持“举国体制”、承办2022年冬奥会有利于中国竞技体育显现性竞争力的提升和冬季项目的发展,但同样存在竞技体育项目布局转型的困难和群众体育基础薄弱的困境。  相似文献
