于航海  扈静  刘高志 《当代体育科技》2020,(12):206-206,209

近年来,随着我国全民健身计划的推行,很多公共场所安装了各式各样的室外健身器材,丰富了人们的体育健身活动,增强了肌肉力量和身体的柔韧性,提高了人们的身体素质。然而,在室外健身器材的使用过程中,人们受伤的案例很多。其质量状况也引起了人们的担忧。本文分析了公共室外健身器材的质量现状,并提供了相关的解决对策。  相似文献   

Managing Health Care in Oregon: The Search for a Civic Bioethics     

Sharon Bracci 《Journal of Applied Communication Research》2001,29(2):171-194

Managed health care deliberations in Oregon point to a "civic bioethics" model to resolve allocation issues through publicly articulated community values and priorities that influence legislative action. Communication practices in the Oregon experiment provide data to develop an evaluative framework to assess public moral deliberation in value-laden contexts such as health care distribution. The Oregon experience also points to dialogical virtues to heighten citizens' ethical sensibilities and political will, discursive tools to inform ethical communication practices in a civic bioethics model.  相似文献   

对四川省散打队十运会赛前训练运动性疲劳的综合监测     

宋剑君  刘樱  赵斌  王纯 《首都体育学院学报》2006,18(6):79-80,95

目的：寻找对四川省散打队十运会赛前训练有关运动性疲劳有效的生理、心理监测措施。方法：采用追踪实验法和统计分析法。以四川省散打队备战“十运会”的五名队员为对象。以周为训练单位。采静脉血：每周一展8时空腹采血，共四周。测试指标：1）生化指标：CK、BU、Hb；2）心理指标：闪光融合频率、自创量表法。结果认为将整体监测与个体监测配合运用，是监测运动性疲劳的可靠手段；而将生化指标与心理指标结合使用，是监测运动性疲劳的有效手段。结论：运用生理生化指标和心理指标对散打运动员进行综合监控，其效果优于单一使用生理生化指标或心理指标。  相似文献   

奥斯本"企业家政府"理论的价值及应用     

彭照辉 《济宁师范专科学校学报》2004,25(2):103-105

“企业家政府”理论强调注重效率 ,提出了一系列切中时弊的主张 ,在行政改革中产生了较大影响。借鉴这一理论 ,政府内部管理应强调“结果为本”而不是“规则为本”,公共服务应以调控引导为主而不是直接提供 ,社会事务应放给社会自我管理而不是政府包揽 ,发展模式上应注重长远发展而不是一时增长。  相似文献   

Developing the evidence base for UK film strategy: the research process at the UK Film Council     

David Steele 《Cultural Trends》2004,13(4):5-21

The UK Film Council established a Research and Statistics Unit in order to gather data relating to film to inform the development of UK Film Council strategy and to provide an information service to the industry, government, the arts and cultural sector and the wider research community. The Research and Statistics Unit draws data from both official and unofficial sources and commissions its own special-purpose studies to gather information relevant to the strategic objectives of the Council. Key tasks are the measurement of the size of the market for film and the various elements of the film value chain, the performance of films supported by the UK Film Council and the performance of UK films in general. Special-purpose research projects currently include a detailed survey of the film production workforce, a study of the economic impact of the UK screen industries and studies of the social impact of local cinemas and the experience of Black- and Minority-led film production companies. A range of industry and official partners are collaborating in these studies. The Research and Statistics Unit also provides statistical and policy analysis relating to the wider policy environment of UK film, including issues such as the future of film tax incentives. This analysis has been developed within the HM Treasury ‘Green Book’ framework with particular reference to understanding market failure in relation to film. Central to the market failure argument is the cultural value of film in both its qualitative and its quantitative aspects. UK Film Council research is placed in the context of the literature on hedonic pricing and contingent valuation. The industrial challenges of increasing cultural value are discussed. Finally, consideration is given to the potential of film to contribute directly to ‘public value’.  相似文献

运动技术录像解析教学实验软件的开发     

刘北湘 《首都体育学院学报》2005,17(3):121-123

运动技术录像解析是运动技术分析中的重要手段,也是大学体育专业学生应该了解和掌握的重要知识技能。但是由于受到各种条件的限制,与教学配套的相关实验并没有得到很好的实施和推广。为适用教学和实验的需要,改善当前的教学条件,作者设计了这样一个可用于运动技术录像解析教学实验的辅助软件。软件经实际使用收到了较好的教学效果。本文就是对这个软件的情况进行介绍,希望能得到同行的关注和见解。这个软件的意义并不在于理论上,而在于它的新型实用方面。  相似文献   

Public library trends     

Nick Moore 《Cultural Trends》2004,13(1):27-57

Public libraries tend to be taken for granted. They can be found in nearly every community and are used by a substantial proportion of the population, particularly the young and the old. Yet the public library service, as it is today, is a relatively recent phenomenon. Despite their origins in the mid-19th century, the widespread network of public libraries is largely the product of the post-war welfare state. The demand for the service grew rapidly during the war and in the immediate post-war period. Provision to meet the demand was constrained initially by the competing demands for reconstruction, but by 1960 the service was ready to expand. The growth was consolidated by the 1964 Public Libraries and Museums Act and was given further emphasis by the 1962 Bourdillon standards (Ministry of Education, 1962). The Act and the standards provided the impetus for what might be described as the golden age of public libraries. This brief period was brought to an abrupt end by the economic crises of the mid-1970s and the subsequent downward pressure on public expenditure. The service managed to hold its own during the late 1970s and early 1980s but since then it has been in decline, with the rate of decline accelerating during the 1990s as new requirements and increasing costs stretched diminishing resources even further, to the point where the overall level of provision now falls well short of the basic standards that were considered to be essential in the early 1960s.  相似文献   

彩色图像信号的非均匀采样和重构     

朱学芳 《现代图书情报技术》2003,35(3):67-69,72

计算机图像处理技术的发展，加速了情报学对图像／视频等较大信息量的快速存储、检索、应用。本文讨论将彩色数字图像信号按一定的规则分割成相同大小的子块，对其进行非均匀降速采样的过程，重采样频率的自动确定、选择原则，重构信号的质量、数据量与子块的尺寸等问题，并以实际的彩色数字图像文件全部用VC 6．0编程实现非均匀降速采样和Hermite插值重构；以实验数据得出了一些有益的结论，并进行了分析讨论。分析方法、实现程序不仅彩色数字图像文件有效，对视频信号也有效的。  相似文献   

对数学“公开课”的几点思考     

曹景明 《中国教育研究与创新》2007,4(2):75-76

现阶段公开课“造假”现象严重，使课堂教学失去了真实性：导向上出现了偏差，应从由重“受术”到重“就道”，由看重“教”到看重“学”，由重“观摩”到重“研讨”三个变化入手，从学生发展及学科特点出发，摒弃“造假”，还课堂教学以真实。  相似文献
