经济因素与奥运会举办城市的归属问题探析

本研究根据<奥林匹克宪章>中对奥运会举办城市遴选的规定,从国际奥委会和候选城市两方面探讨了经济因素对双方的决定作用.对于国际奥委会而言,奥运会巨大的规模,全球目前面临的经济危机和数量众多的比赛场馆的建设,需要坚实的经济基础,奥运会举办国家和城市的经济实力是前提.对于奥运会举办城市来讲,提出诱人的经济条件是获得选票的     

足球教练员决策行为的理论研究

足球教练员在训练和比赛的过程中要不断地做出各种决策.足球教练员的决策分为战略性决策和战术性决策.足球教练员决策过程中信息的获取和分析,对决策的科学化程度有着直接的关系.足球教练员自身的综合素养、思维方式、性格特征、经验积累,以及外部环境和条件的制约,决定了足球教练员的决策只能是建立在一种有限的理性基础之上.     

框架效应下人格特征对高校高水平运动员 决策行为的影响作用研究

探讨正负信息呈现方式对高校高水平学生运动员的运动决策行为及人格特征的影响作用.研究方法:采用自编运动员决策问题问卷和大五人格量表(中国修订版),以分层抽样的方法,抽取高水平运动员260人为研究对象,随机分为两组,正面框架组(n=126),负面框架组(n=123),对两组间被试的方案选择进行X2检验,方案选择与人格特征的关系进行t检验.结果:接受正面框架实验情景的被试,保守和冒险方案选择人数比例相当,分别为42.86%和57.14%;负面框架组的被试,只有17.07%选择保守方案,差异有统计学意义.正面框架下,外向性维度得分高的被试个体倾向于冒险,愉悦性维度得分高的被试个体倾向于保守;但在负面框架中,差异无统计学意义.负面框架下被试个体更倾向于冒险;外向性和愉悦人格特征与运动决策行为有关.     

A knock to the system: A new sociotechnical systems approach to sport-related concussion

Broader contextual factors that influence concussion management have tended to be overlooked. To address this, the present study used a sociotechnical systems approach to identify perceived responsibilities and applied strategies for three domains of concussion management (i.e., prevention, identification and treatment). Participants were 118 members of the community rugby union system in Australia (69.2% male). Participants from throughout the rugby system (e.g., players, parents, coaches, club management) were asked open-ended questions about their perceived responsibilities and the strategies they use for concussion management. It was found that (a) proper training, technique correction and education were recurrent prevention themes; (b) the majority of key stakeholders felt that they could consistently identify concussion; however, medical aids (medics) were the only system actors who stated a responsibility to use standardised concussion assessment measures and (c) less than one third of the respondents indicated their involvement in treating concussion. This study identifies specific junctures in the system that prevents effective concussion management strategies. A sociotechnical systems approach improves the understanding of concussion prevention, and management beliefs and behaviours.     

Embodied learning and school-based physical culture: implications for professionalism and practice in physical education

We write as critical theorists, who consider that in terms of scoping out robust conceptual elaborations which are suitable for contemporary schooling, that physical education has ground to make up connecting theory with practice and practice with theory. We advocate that aspects of existentialism and phenomenology can provide a theoretically sound basis on which to argue that embodied learning should be the foundational cornerstone of physical education programmes. To avoid embodied learning becoming overly learner centric and insular, we advance Merleau-Pontian informed ideas on how learning could flourish when an individual and embodied focus merges with a school-wide physical culture agenda which is underpinned by social and moral theorizing. In developing our focus on merging embodied learning and physical culture, we draw upon MacIntyrean views on the goods which are internal to practice and extend thinking on how these goods could merge with the diverse aims and intentions informing the culture and ethos in schools. In pursuing these ambitions, we outline the constructive activist-based benefits of teachers working within subsidiarity-based school communities where pedagogical decisions are made at a level consistent with realizing whole schools aims. This is in spite of our acknowledgement that the lack of career-long professional learning adds to the difficulty of achieving these aims. In conclusion we argue that if physical education is to become a pivotal component of realizing a diverse range of whole school aims there is a need for greater professional engagement with pedagogical approaches that attempt to derive greater meaning from learners movement experiences and which help learners to understand better both their own identity and the ethos of the school context and environment they share with others.     

中介式调节作用在肥胖青少年锻炼经历与锻炼行为之间的关系研究

运用结构方程模型对均衡决策和自我效能在锻炼经历和锻炼行为中的作用进行分析,探讨肥胖青少年锻炼行为与锻炼经历、均衡决策、自我效能之间的关系.结果显示:均衡决策、自我效能在锻炼经历和锻炼行为的关系中起中介作用;自我效能对锻炼经历与均衡决策的关系,以及均衡决策与锻炼行为的关系起调节作用;均衡决策的中介效应受到自我效能的调节,并且均衡决策也是自我效能和锻炼行为关系的中介变量.自我效能对锻炼行为起间接中介作用,调节了锻炼经历与均衡决策、均衡决策与锻炼行为之间关系的作用轨迹和特征,促进了锻炼经历对锻炼行为的预测作用,影响了肥胖青少年的锻炼行为.     

企业异质性与贸易中介理论研究新进展

新新贸易理论诞生近十年来,贸易理论家围绕企业异质性假定进行了细致而富有成效的拓展研究。其中引人注目的是融入贸易中介的分析,打破了已有研究关于直接出口的局限,并分别基于异质性和企业内生边界视角,解释了中介技术和不完全合约对企业直接出口和中介出口等不同出口决策及福利分配的影响。本文梳理了国外最新文献中企业异质性与贸易中介理论的研究进展,解析了将贸易中介引入新新贸易理论的微观机理,并展望了其未来的发展方向。     

煤炭行业去产能、调整资产结构对煤炭经济的撬动效应

关注联结:复杂性科学视野下大学通识教育课程理论的思考

近现代大学通识教育课程设计主要基于科学课程的理论,当前大学课程存在的主要问题是缺乏知识的联结。复杂性科学关于整体性、关联性和开放性的理论观点,为通识教育课程的研究与创新提供了新的思路。基于复杂性科学的视野,大学通识教育课程理论应当从传统的精义论、均衡论和进步论转向联结论;通识教育的课程编制也应从学科中心、问题中心和方法中心转向以主题为中心的关联组合。
