公共体育场馆功能改造之理论逻辑与现实困境--以洪山体育中心为例     

陈元欣  陈磊  刘恒  郑芒芒 《上海体育学院学报》2020,(5):37-46

运用实地考察法、问卷调查法、主成分分析法等,对公共体育场馆功能改造的理论逻辑与现实困境进行剖析。认为消费者需求与公共体育场馆功能之间存在相互作用的理论逻辑,据此提出基于消费需求识别的公共体育场馆功能选择路径,以洪山体育中心为例进行实证分析。同时,对当前公共体育场馆功能改造在土地利用、消费场景营造、利益主体参与机制和改造程序等方面面临的现实困境进行总结。提出:创新用地政策,鼓励公共体育场馆进行功能改造;加强公共体育场馆消费场景营造;健全利益主体参与机制;建立健全多部门合作的公共体育场馆功能改造工作机制。  相似文献   

Role of objectively measured sedentary behaviour in physical performance,frailty and mortality among older adults: A short systematic review     

Asier Mañas  Borja del Pozo-Cruz  Francisco José García-García  Amelia Guadalupe-Grau 《European Journal of Sport Science》2017,17(7):940-953

Sedentary behaviour (SB) has recently emerged as an independent risk factor for different health outcomes. Older adults accumulate long time in SB. Understanding the role that SB plays on health is crucial for a successful aging. This short systematic review summarizes the current evidence related to the effects of objectively measured SB on frailty, physical performance and mortality in adults ≥60?years old. The literature search produced 271 records for physical performance (n?=?119), frailty (n?=?31), and mortality (n?=?121). Finally, only 13 articles fulfilled the inclusion criteria and were included in this review. All articles but one included in the physical performance section (n?=?9) showed a negative association between longer time spent in SB and physical performance. A significant association of SB with higher odds of frailty was found, however this association disappeared after adjusting for cognitive status. Lastly, two of the three included studies showed positive associations between SB and mortality, but this effect decreased or even disappeared in the more adjusted models. In conclusion, there is consistency that SB is negatively associated with physical performance. However, the relationship between objectively measured SB and frailty incidence and mortality rates remains unclear and deserves further research. The use of homogenous criteria to assess SB and the inclusion of more robust research designs will help clarifying the independent effects that SB could have on physical performance, frailty, and mortality. This will ultimately help designing more efficient and comprehensive physical activity guidelines for older adults.  相似文献

重视学生特性,实现思想政治课教育功能最大化     

杨明珠 《楚雄师范学院学报》2011,26(7):51-55

促进人的个性发展是教育长期追求的重要目标。思想政治课在学校的课程体系中居于首要位置,在提高学生的文化素养、道德修养及促进学生的个性发展等方面发挥着不可替代的作用。而艺术院校的学生在个性及其专业特性上具有明显的特点,因而,在思想政治课教育中,重视和利用教育对象的特殊性并将其与教育活动紧密联系,使教育活动自觉反映并符合学生身心发展的需求、学生的个性发展与教育活动趋向良性互动的状态,实现艺术院校思想政治课教育功能最大化的目标。  相似文献   

Learning executive function skills by playing focused video games     

《Contemporary educational psychology》2017

The objective of the present study was to determine whether it is possible to design a video game that could help students improve their executive function skill of shifting between competing tasks and the conditions under which playing the game would lead to improvements on cognitive tests of shifting. College students played a custom video game, Alien Game, which required the executive function skill of shifting between competing tasks. When students played for 2 h over 4 sessions they developed significantly better performance on cognitive shifting tests compared to a control group that played a different game (d = 0.62), but not when they played for 1 h over 2 sessions. Students who played Alien Game at a high level of challenge (i.e., reaching a high level in the game) developed significantly better performance on cognitive shifting tests compared to controls when they played for 2 h (Experiment 1, d = 1.44), but not when they played for 1 h (Experiment 2). Experiment 3 replicated the results of Experiment 1 using an inactive control group, showing that playing Alien Game for 2 h resulted in significant improvements in shifting skills (d = 0.78). Results show the effectiveness of playing a custom-made game that focuses on a specific executive function skill for sufficient time at an appropriate level of challenge. Results support the specific transfer of general skills theory, in which practice of a cognitive skill in a game context transferred to performance on the same skill in a non-game context.  相似文献
