我国高尔夫球奥运选手与世界优秀选手一号木数据对比分析     

赵紫龙 《河北体育学院学报》2020,34(6):85-90

采用文献资料法、实地考察法、数理统计法和对比分析法，对我国奥运选手和世界优秀选手的一号木数据进行分析。发现，在实地考察的球洞中，世界优秀选手全四轮均使用一号木开球，而我国男子选手则是一号木、三号木交替开球，可能是由于对自身一号木开球技术不够自信；我国男子选手的一号木平均开球距离、上球道率较世界优秀选手均差距较大；我国女子选手的一号木平均开球距离与世界优秀选手较为接近，但上球道率有待提高。建议，男子选手加强开球距离和上球道率的训练，女子选手加强上球道率的训练；冯珊珊进一步提升开球距离；在比赛前要对场地进行多次熟悉，找到合适的开球策略。  相似文献

Social support and cultural distance: Sojourners’ experience in China     

《Int J Intercult Relat》2021

Previous research has pinpointed that social support from host, co-national, and other international friends plays a pivotal role in successful adaptation to a new culture, yet research on this topic pertaining to China is inadequate. As such, using a cross-sectional sample of sojourners (N = 199) in major Chinese cities, the current study examines the relationship between sojourners’ self-reports of social support from the three sources and two psychological adaptation variables (i.e., anxiety and well-being) as well as the moderating effect of objective cultural distance. Regression analysis indicates that perceptions of host and international support are significant negative predictors of anxiety and positive predictors of psychological well-being. In addition, cultural distance moderated these predictive associations: host support and international support had a stronger negative association with anxiety and host support had a stronger positive association with well-being for participants whose cultural distance to China was lower compared to those whose cultural distance was higher. This study enhances our understanding of the dynamic interplay between social support and cultural distance in cross-cultural adaptation research within a Chinese cultural context.  相似文献   

“翻转课堂教学模式”在小学体育教学改革实践中的运用研究--以小学三年级《立定跳远》教学为例     

桂洁 《当代体育科技》2020,(12):11-13

立定跳远,在小学三年级的体育教材中被列为学习跳跃的主要教学内容,为了提高了教学的效率和质量,教师经过多次教学改革实践,从传统的"挤牙膏式"的教学,再到套入情境的教学,最后运用翻转课堂教学模式进行教学,一步步地实践并对比和反思,发现运用"翻转课堂教学模式"的立定跳远课不但有趣还有效,教学效果得到明显提高。  相似文献   

An alternative to fortified schools: Using crime prevention through environmental design (CPTED) to balance student safety and psychological well-being     

Daniel Lamoreaux  Michael L. Sulkowski 《Psychology in the schools》2020,57(1):152-165

In response to tragic school shootings, heightened attention has been devoted to making schools safer through the implementation of security features. However, excessive security measures have a negative impact on school climate, student functioning, and academic achievement. Therefore, there is a critical need to design schools that are safe and secure, yet also welcoming and comfortable. As a promising approach in this regard, crime prevention through environmental design (CPTED) is an architectural philosophy that aims to deter criminal or antisocial behavior through environmental design, and it includes a focus on natural surveillance, access control, and territorial reinforcement. This review discusses pertinent effects of the school environment on student outcomes, extant research on the impact of visible security measures, the relationship between students’ perceptions of safety and academic functioning, and how using CPTED could concomitantly address the physical safety and psychological comfort of students at school.  相似文献   

我国单项体育协会改革的软法之治     

黄亚玲 《体育科学》2020,(2):15-23

新时代单项体育协会的改革与发展,不仅需要硬法也需要构建完善的软法体系加以保障,这是现代体育治理的客观要求。通过探讨软法对单项体育协会自治发展的作用,梳理单项体育协会脱钩实体化后运用软法保障其权责利的理论与实践依据。研究提出,脱钩与实体化后的单项体育协会,需要通过制定软法完善和补充硬法鞭长莫及的问题,发挥软法在单项体育协会治理中柔性、灵活性及协商性约束的优势,使其成为平衡、协调、规制各主体利益的“内部法律”,促使软法与硬法相衔接,确保单项体育协会改革的有效性与实效性。  相似文献   

Strength,Weakness, Opportunity,Threat (SWOT) Analysis of the Adaptations to Anatomical Education in the United Kingdom and Republic of Ireland in Response to the Covid-19 Pandemic     

Georga J. Longhurst  Danya M. Stone  Kate Dulohery  Deirdre Scully  Thomas Campbell  Claire F. Smith 《Anatomical sciences education》2020,13(3):301-311

The Covid-19 pandemic has driven the fastest changes to higher education across the globe, necessitated by social distancing measures preventing face-to-face teaching. This has led to an almost immediate switch to distance learning by higher education institutions. Anatomy faces some unique challenges. Intrinsically, anatomy is a three-dimensional subject that requires a sound understanding of the relationships between structures, often achieved by the study of human cadaveric material, models, and virtual resources. This study sought to identify the approaches taken in the United Kingdom and Republic of Ireland to deliver anatomical education through online means. Data were collected from 14 different universities in the United Kingdom and Republic of Ireland and compared adopting a thematic analysis approach. Once themes were generated, they were collectively brought together using a strength, weakness, opportunity, threat (SWOT) analysis. Key themes included the opportunity to develop new online resources and the chance to engage in new academic collaborations. Academics frequently mentioned the challenge that time constrains could place on the quality and effectiveness of these resources; especially as in many cases the aim of these resources was to compensate for a lack of exposure to cadaveric exposure. Comparisons of the actions taken by multiple higher education institutions reveal the ways that academics have tried to balance this demand. Discussions will facilitate decisions being made by higher education institutions regarding adapting the curriculum and assessment methods in anatomy.  相似文献   

Social influence on endorsement in social Q&A community: Moderating effects of temporal and spatial factors     

《International Journal of Information Management》2021

This study examines the impacts of social influence, which are manifested by popularity and source credibility, on social endorsement in social Q&A community; and how the relationship is impacted by temporal-spatial factors. By collecting panel data from a large platform, the results of an econometric model demonstrate that popularity and source credibility are positively associated with social endorsement. With respect to the moderation effects, the results further show that time distance strengthens the effect of popularity on the social endorsement, but undermines the effect of source credibility; while crowdedness plays the role that strengthens the impact of popularity on the social endorsement, it has no significant moderating effect on the relationship between source credibility and social endorsement. Both theoretical and practical implications are discussed.  相似文献
