2017年世界男排联赛中国男排与对手比赛技术效果对比分析          下载免费PDF全文

陈贞祥  赵德峰  沈琼 《体育科研》2019,(2):97-108

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   

体育赛事转播权的多重解读及其类型化保护     

龚韬  刘智瑜  何炼红 《武汉体育学院学报》2019,53(11):43-48

体育赛事转播权是一种新兴的复合型权利，是指电视台、视频网站、直播平台等转播机构就其制作的体育赛事节目和提供的转播信号享有的著作权或者录音录像制品权、广播组织权，同时也是指赛事组织者就体育赛事享有的"转播许可权"。对其不同层次的内容应当分别予以解读，而不宜笼统地在"体育赛事转播权"这一概念下进行讨论。对赛事组织者的权利保护，有赖于体育法对其权利予以法定化；对相应的著作权人和邻接权人的保护，需要在完善著作权法的基础上，坚持作品独创性判断标准，并提升邻接权的保护水平。  相似文献   

基于单向流固耦合的不同风速下帆板帆翼空气动力性能仿真     

雷晓珊  马勇  蔺世杰 《武汉体育学院学报》2019,53(11):95-100

目的：探究不同风速对帆板帆翼结构以及周围流场的影响。方法：以奥运女子级别的Neil Pryde RS：X帆板帆翼为研究对象，考虑空气动力与结构的流固耦合效应，利用ANSYS Workbench进行单向流固耦合分析。结果：Realizable模型适合计算帆翼周围的流场湍流度，在风速为2m/s时帆翼升阻比最大；随着风速的增大，帆翼面发生变形和振动会导致风激振现象、背风面产生明显的涡脱现象，且帆翼表面应力区增大，全帆的应变逐步增加。结论：不同风速下的帆翼迎风面和背风面的压力分布、帆翼整体空气动力有一定差异，运动员比赛中应该根据当时风况调整帆翼参数。  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   

登上领奖台：加拿大冬奥备战的治理经验及其启示     

任慧涛  楚金玲  易剑东 《南京体育学院学报(社会科学版)》2019,2(1):39-49

为备战2010年温哥华冬奥会，加拿大联邦政府设计了“登上领奖台”战略，委托OTP组织负责财政援助的划拨和绩效管理。OTP组织采用“决策层—执行层”的双层治理架构，以“奖牌至上”为原则，创建了由“项目文化”“以往成绩”“夺牌潜力”“领先优势的可持续性”4个一级指标的协会分层分类资助制度，邀请国家奥委会和残奥委、国家运动项目协会、体育科研院所等利益相关者组成协同治理网络。通过梳理加拿大治理经验，建议我国当前的备战2022年北京冬奥工作，应重视“一臂之距”理念，明确政府在冬奥备战中的职责；尊重专业自治准则，锻炼社会力量成为竞技体育治理主体；改进绩效管理模式，优化冬奥备战财政资金的申请和使用程序；重视科学创新，促进体育智库组织网络化。  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

Contemporary school knowledge democracy: possible meanings,promising perspectives and necessary prerequisites     

Eleni Katsarou  Konstantinos Sipitanos 《Educational Action Research》2019,27(1):108-124

ABSTRACT

The basic aim of this paper is to discuss the concept ‘Knowledge Democracy’ (KD) and what it can mean in the school context, its implications on knowledge production and dissemination and on the educational practices. We try to enrich this discussion by presenting action research projects to provide case studies of how thinking about KD can reshape educational practice. We consider that the discussion on KD has to be enriched as the concept seems very promising with good prospects towards school’s democratization. On the other hand, as it is quite new, it can encompass internal contradictions that can cause problems at the level of practice. So, we consider very important any contribution to this discussion not as another theoretical sample of the debate on the ‘politics of knowledge’, but because any improvement at the thinking of the issue can be reflected on school practices. Any challenge to traditional politics of knowledge can lead to a deeper understanding of the world of schooling and to transformations through new discourses and new approaches to teaching and learning in school.  相似文献   

Promoting schoolchildren’s self-esteem in physical education: testing the effectiveness of a five-month teacher training     

Benjamin Rubeli  Esther Oswald  Achim Conzelmann  Jürg Schmid  Stefan Valkanover 《Physical Education & Sport Pedagogy》2020,25(4):346-360

ABSTRACT

Background: Schoolchildren’s personality development is considered a central goal of physical education (PE). With regard to the relationship between psychological well-being and global self-esteem over the life course, the promotion of positive self-esteem is an issue of particular significance. Past research revealed that PE taught with an individualized teacher frame of reference (iTFR) and a reflexive teaching style is associated with positive effects on facets of children’s perceived sports competence. However, it remains an open question whether this teaching styles has the potential to promote positive self-esteem.

Purpose: The present study investigated whether a five-month teacher training, aimed to enhance the teachers’ iTFR and their reflexive teaching style in PE, has a positive effect on students’ perceived sports competence and their global self-esteem. To analyse the implementation quality, changes in students’ perceived iTFR and perceived reflexive teaching style were investigated.

Method: A total of 21 teachers were assigned to either an intervention group (n?=?13), receiving the five-month teacher training, or a control group (n?=?8) consisting of regular teaching without teacher training. The teacher training encompassed five three-hour consecutive sessions during which the teachers acquired theoretical and practical knowledge about the promotion of competence perceptions in PE with a reflexive teaching style and an iTFR. Between the sessions, the teachers were instructed to implement an iTFR and a reflexive teaching style into their own PE classes. To evaluate the effects of the teacher training, their students’ (N?=?315, 53.7% girls, M_age?=?13.2 y, SD_age?=?1.3 y) perceived teaching style (iTFR and reflexive teaching), perceived sports competence and global self-esteem were measured with paper-pencil questionnaires at three measurement points (pre, post and follow-up).

Findings: Linear mixed effect models showed that students of the intervention group reported an increase in their teachers’ reflexive teaching style, but there were no changes with regard to iTFR. With regard to students’ perceived sports competence and global self-esteem, there were significant interaction effects between time and group over a period of eight months (from pre-test to follow-up), indicating positive effects on these self-concept dimensions due to the teacher training.

Conclusion: The present study indicates that a long-term teacher training supports PE teachers to implement teaching styles with the aim to promote students’ self-concept. Furthermore, the findings lead to the assumption that a more pronounced iTFR in combination with an enhanced reflexive teaching style has the potential to positively influence schoolchildren’s perceived sports competence and global self-esteem.  相似文献
