协同导向是美国青少年体质健康政策的突出特征,主要体现在政策文本协同和政策制订协同两方面.在政策文本协同方面,通过梳理历年来体质测量、体育、教育、校园卫生和营养等方面的政策演进过程,发现其体现出较明显的健康促进导向作用.在政策制订协同方面,除了政府相关部门外,社会组织和社会精英人物也都积极参与政策制订,形成了国家政府部门和各界参与的有机融合.我国青少年体质健康亦面临类似问题,可借鉴美国经验,注重体育与营养政策的协同作用,注重跨界政策制订主体的协同参与,强化学校和社区等场域的协同连接,凸显学生校园营养行为的国家责任. 相似文献

The recent migration of 65,000 children across the southwestern border, coupled with allegations of abuse by the U.S. Border Patrol, enables the investigation of an overlooked immigrant category: the unaccompanied youth migrant. Analyzing audience responses to news reports of the abuse, we find that established disparaging immigrant tropes apply, describing the children as an economic burden, disease carriers, and offspring of irresponsible families. We uncover two new themes: Youth migrants are channels whereby criminals may infiltrate the U.S., and manipulate legal authorities to remain in the U.S. Finally, we demonstrate how global compassion is strategically deployed to qualify harsh retaliatory measures. 相似文献

Compared to traditional tennis shoes, using 0-drop shoes was shown to induce an immediate switch from rear- to forefoot strike pattern to perform an open stance tennis forehand for 30% of children tennis players. The purpose of the study was to examine the long-term effects of a gradual reduction in the shoe drop on the biomechanics of children tennis players performing open stance forehands. Thirty children tennis players participated in 2 laboratory biomechanical test sessions (intermediate: +4 months and final: +8 months) after an inclusion visit where they were randomly assigned to control (CON) or experimental (EXP) group. CON received 12-mm-drop shoes twice, whereas EXP received 8?mm then 4-mm-drop shoes. Strike index indicated that all CON were rearfoot strikers in intermediate and final test sessions. All EXP were rearfoot strikers in intermediate test session, but half the group switched towards a forefoot strike pattern in final test session. This switch resulted in a decreased loading rate of the ground reaction force (?73%, p?=?.005) but increased peak ankle plantarflexors moment (+47%, p?=?.050) and peak ankle power absorption (+107%, p?=?.005) for these participants compared with CON. Biomechanical changes associated with the long-term use of partial minimalist shoes suggest a reduction in heel compressive forces but an increase in Achilles tendon tensile forces. 相似文献

Purpose: This study investigated the effect of summer camp session context on Russian girls’ physical activity (PA). Method: Girls (n = 32, Mage = 10.7 years, SD = 0.6 years) from a resident summer camp taking place in the Vologda Region of Russia were exposed to 1 session context/day (i.e., free play, organized with no choice, organized with choice) on Wednesday, Thursday, and Friday for 3 weeks, with the context order counterbalanced across the 3 weeks. The organized session sport/game changed weekly. The primary outcome was accelerometer-assessed PA. Repeated-measures mixed models were used to analyze all outcome data. Results: Findings showed that girls spent a greater percentage of session time (%time) in moderate-to-vigorous PA (p < .001; effect sizes between free play and organized with no choice and organized with choice, respectively = .60, .42) and moderate PA (p < .001; effect size = .57, .39) and a lower %time in light PA (p < .001; effect size = .55, .52) in organized PA contexts compared with free play. Conclusions: This study provides novel findings in a Russian setting, suggesting that a well-planned, organized camp session can elicit higher PA levels in girls, relative to a free-play session. 相似文献

摘要:城市化是国家经济制度、政治体制和社会形态发生变革的重要引擎,在体育领域,城市化进程的结束则标志着体育发展方式的重要转型。有鉴于此,以我国城市化进程中的体育发展现状为研究对象,主要采用文献资料法和比较分析法,结合英、美2国的实例,详细梳理城市化进程结束后,即城市化水平达到50%背景下,城市化对我国体育人口规模、体育空间布局、体育产业结构以及体育管理体制所造成的影响,其研究结果对于厘清现阶段我国体育发展的症结及未来我国体育改革的对策均具有重要的理论意义及实践价值。研究认为:城市化作为一种人类社会发展的普遍规律,始终影响着体育发展的进程与走向;城市化水平与体育发展的现实水平存在着高度的相关性,当城市化水平达到50%的时候,标志着体育将进入到一个全面转型的发展时期;我国已经进入到城市化进程过半的关键时期,城市化对体育发展方式的影响已经全方位体现出来,城市化引致的人口聚集成为了体育人口发展的基础,城市化引发的城市扩张导致了体育空间布局的整合,城市化催生的结构调整搭建了体育产业发展的平台,城市化激发的制度改革完善了管理体制发展的模式。 相似文献

Abstract The evolution of moral panics is dependent on the particular social context and the ability of certain issues to trigger concern within society. In this paper, the authors have employed a cross‐comparative study of the heavy metal music subcultures in Singapore and Malaysia to understand the differences in the issues that generate such panics based on the socio‐political context of each country and its current concerns. Although the youth involved in both cases are marginalised male Malays, the framing of their alleged deviance and criminality permits, in the case of Singapore, only a limited possibility for moral panic creation given the conservative socio‐political governance that limits allegations such as ‘Satanism’. In the case of Malaysia, where a ‘large‐scale’ moral panic involving black metal emerged in 2001, the recent trend towards Islamisation gave fodder for the condemnation of black metal based on the allegations of the anti‐Islamic behaviour of Muslim youth involved in the black metal scene. In both cases, such groups were exploited by parties claiming to defend the social fabric of the moral majority, but in the latter case it took on grave implications due to the extent of the state and public response. This paper thus argues that the framing of these moral panics is an important component determining the relative ‘success’ of the panic or its ability to capture public and state imaginings. 相似文献

ABSTRACTIn the 1950s and early 1960s, the British teenager was presented as a symbol of generational rebellion in the popular press, social investigations, and much political debate. We draw on oral histories, newspapers and the archives of prominent social surveys to question this presentation. By examining how working-class teenagers and their parents experienced and remembered the post-war years, we identify a disjuncture between the literature on moral panic and the widespread evidence of intergenerational cooperation between parents and children. Many working-class parents, enjoying newfound economic security, felt able to encourage their children to enjoy more adventurous lives. 相似文献

运用Elman神经网络模型对2010—2050年河北省人口数进行预测,经过分析得出,河北省的人口老龄化具有以下几个特征:老年人口规模庞大,增长迅速;老龄化程度超前于河北省的经济发展水平,社会负担沉重;老年人口的高龄化趋势明显;老年人口的性别差异较大;老年人口的分布具有明显的差异性等。根据这些特征为河北省应对人口老龄化提供了一些对策建议。 相似文献

借鉴成本收益理论,基于农业转移人口市民化意愿和经济理性的微观视角,构建我国农业转移人口市民化微观决策机制理论模型,并根据在重庆进行的实地调查数据进行实证检验。研究表明:农业转移人口在城市就业创业收入及其社会网络、文化程度以及农业生产成本和农村建房成本与转户迁移人数正相关,而城市劳动力素质、城市住房价格、城市日常生活开支与转户迁移人数负相关。农业转移人口在城市稳定就业后,根据转户迁移的收益与成本评估进行市民化决策,只有收益大于成本时才进行转户迁移;否则会继续“流而不迁”或返回农村。因此,仅仅拆除城乡户籍制度的藩篱并不能促成农业转移人口的快速市民化,还必须有效提高农民转户迁移的收益,并降低其成本。 相似文献

推进城镇化是增加我国农村消费需求,扩大内需的重要突破口。采用2002—2012年我国省际面板数据考察城镇化、农村人口结构、消费结构升级等因素对农村居民消费的影响,结果表明:城镇化对农村居民消费增长具有显著的促进作用,且存在地区差异,东部地区城镇化对农村居民消费增长的作用大于西部地区;城镇化对我国农村居民消费的影响存在显著的单一门槛效应,门槛估计值为0.589,在城镇化水平高(大于0.589)的地区,城镇化对农村居民消费的促进作用更大,但目前我国大部分省区的城镇化水平还未达到门槛值。应进一步加快我国城镇化进程,尤其是中西部次发达地区的城镇化进程,充分发挥城镇化对农村居民消费的促进作用。 相似文献
