足球运动在世界范围内的普及化与社会化程度日益增强,各国(地区)若要获得全球化竞争中的优势,应注重探讨社会与足球运动发展的关系。通过对1993-2017年131个国家(地区)的人类发展指数与足球排名积分的面板数据建模,以揭示两者之间的关系。研究结果表明,不同国家(地区)的人类发展指数对足球运动发展的影响应建立个体和时点双固定效应模型,模型最高的R2为0.871 32,F检验值为71.014 65,P<0.001,该模型具备较高的解释能力。结论:固定效应模型在考虑历时性因素与不宜观测因素后,在1993-2017年阶段,人类发展指数对于足球运动的发展作用存在分化现象,尤其对亚洲与人口大国的足球运动发展存在制约作用,对南美洲与中等人口国家存在促进作用,人类发展指数与足球运动发展存在一定的或然关系。人类发展指数反映了社会发展的综合水平,对于存在制约效应的国家而言,应当着重考虑社会其它领域(经济、教育、医疗卫生等)与足球运动的互动、协同与融合发展。  相似文献

作为遮体御寒之用的服装,一旦冠以体育的名号,其身价大增,魔力四射。体育服装的价值到底体现在什么地方?价格是如何决定的?使用价值是否还仅仅局限在遮体御寒?国外的品牌如adidas、nike、puma等在中国体育服装市场“肆意泛滥”的时候,我国的体育服装业应如何应对这些挑战?这些都是摆在我们面前的亟待解决的问题。本文试用西方经济学和马克思主义政治经济学的理论来分析这些问题。  相似文献

This article is about personally driven professional development through the use of reflective self-study. The argument that teachers need to take responsibility for their own learning while also taking decisions on how and in what areas to develop is strongly made throughout the article. Data for this article were gathered over a 10-year period where the author engaged in several studies using self-study as methodology. Between studies, the author kept using reflective self-study as a professional development tool, and it is these data between various studies that were analysed using thematic and reflective analysis. Such analysis resulted in various overarching themes that show how reflective self-study can be of benefit if used by teachers researching their own classrooms. Benefits include teachers taking full ownership of their learning, relevance of learning, learning that is ongoing and not restricted to specific times and places, taking problematic situations as learning opportunities and how other sources take on new relevance through reflective self-study. Some implications for teacher-education programmes and current school structures are also discussed.  相似文献

This paper explores the growing importance of measures of progress in judgements of schools’ effectiveness in England, with a focus on the role of the early years (settings for children aged 2–5) in providing data for these measures. Qualitative data from a research project involving three diverse school-based and pre-compulsory early years settings are used to explore how teachers and school leaders prioritise the collection of data in their every-day practice, in order to show how children make continual progress. The need for a narrative of progress as children move up through the primary school, an ‘Ofsted story’ for the school inspection service, is discussed alongside recent policy which requires a ‘baseline’ assessment at age four. We argue that there is a reification of progress in schools and early years settings, and that this changes the status of early years within the sector.  相似文献

This study analysed The 8th Online Survey of Adolescent Health and Behaviour in 2012, which is a government-approved statistical survey of Internet use and patterns in Korea. We conducted a propensity score matching (PSM) to control for economic status differences between monocultural and multicultural families and an ANOVA to estimate the effects of multicultural family status, adolescents’ gender, school grades, locality, and parents’ academic background on adolescents’ Internet use (for studying and entertainment). The study revealed the following: with regard to Internet use patterns, adolescents from both monocultural and multicultural families selected gaming as their first choice, followed by studying and data searching. Furthermore, main and interaction effects of independent variables on adolescents’ time spent on the Internet for studying were not significant. However, the interaction effects of multicultural family status and mothers’ academic background on adolescents’ time spent on the Internet for entertainment were statistically significant. Specifically, adolescents’ time spent on the Internet for entertainment was higher in multicultural families with mothers whose education level was lower than middle school. Finally, we suggested that the government should provide full support to less educated mothers in multicultural families for effectively and constructively controlling their children’s Internet use and teaching it to them.  相似文献

The present study aimed to estimate the use of positive and negative parenting practices in Ukraine and explore relationships between parenting practices, intimate partner violence (IPV), alcohol use, and sociodemographics. Parents of children (N = 320) ages 9–16 from three Ukrainian regions answered questions from the Alabama Parenting Questionnaire (APQ), the Revised Conflict Tactics Scales (CTS-R), Family Adaptability and Cohesion Evaluation Scale (FACES), and the Alcohol Use Section of the Drinking and Drug History and Current Use Patterns questionnaire. Ukrainian parents who reported lower use of alcohol, balanced family functioning and lower intimate partner violence were more likely to use positive parenting and less likely to use negative parenting practices. Parents with lower education were more likely to use negative parenting practices. Furthermore, alcohol use, IPV, parent education and higher family income were significantly and indirectly related with positive and negative parenting scores. The model explained 61% of variance in the positive parenting, 67% in the negative parenting.  相似文献
