大学教师运动锻炼与健康状况研究   总被引:2,自引:0,他引:2  
运用问卷调查法对大学教师的运动锻炼情况和身体健康状况、态度、兴趣、参与程度等因素进行分析,结果表明,教师健康状况令人担忧,特别是年龄较高的教师健康水平下降速度明显,年轻教师身体状况也不容乐观。体育设施不足、经费匮乏、方法不当是阻碍健身计划实施的重要因素;体育意识淡泊、锻炼效果不佳是影响广大教师进行体育活动不可忽视的心理因素。  相似文献

在决策过程中,解决信息不完备的问题是情报工作的核心要义,通过情报基础建设来为情报任务响应做好准备,实现情报事业的可持续发展,是情报学术不可忽视的研究议题。本文基于前期相关研究对情报响应的基础条件内涵及其内容进行了基本界定,运用生态理念梳理了情报响应的基础业务系统机理,并对中美两国进行情报响应的环境要素条件和主体要素条件进行了比较分析,提出了实现我国情报响应持续发展的基础条件要求,具体包括:加强对科技信息资源建设以及跨领域信息资源的建设;创建具有中国特色的情报教育发展体系,打造情报人才多样化发展的情报教育培养模式;完善情报机构的管理与评价模式,实现情报基础条件对情报任务响应的持续支持。  相似文献

This paper explores the correlation between metropolitan social and economic conditions and corporate arts support in the United States. It is hypothesized that the transition from a manufacturing sector economy to an advanced service sector economy is an important local factor for the increase in corporate arts support.By panel analysis, in eleven metropolitan areas between 1977 and 1991 changes in corporate arts support have been correlated with changes in social and economic conditions, i.e., service sector and manufacturing sector employment, service sector and manufacturing sector income, population's educational attainment, and the degree of dominance by the leading local arts supporting industry.Corporate arts support is higher in metropolitan areas where the population is better educated (=+0.60), the local service sector generates more income (=+0.37) and the local manufacturing sector generates less income (=–0.22).Corporations from the manufacturing sector are mostly indifferent towards arts support. In contrast, corporations from the service sector are supportive of the local arts but they also respond swiftly to a loss in their earnings by discontinuing their arts support.  相似文献

Searching online information resources using mobile devices is affected by small screens which can display only a fraction of ranked search results. In this paper we investigate whether the search effort can be reduced by means of a simple user feedback: for a screenful of search results the user is encouraged to indicate a single most relevant document. In our approach we exploit the fact that, for small display sizes and limited user actions, we can construct a user decision tree representing all possible outcomes of the user interaction with the system. Examining the trees we can compute an upper limit on relevance feedback performance. In this study we consider three standard feedback algorithms: Rocchio, Robertson/Sparck-Jones (RSJ) and a Bayesian algorithm. We evaluate them in conjunction with two strategies for presenting search results: a document ranking that attempts to maximize information gain from the user’s choices and the top-D ranked documents. Experimental results indicate that for RSJ feedback which involves an explicit feature selection policy, the greedy top-D display is more appropriate. For the other two algorithms, the exploratory display that maximizes information gain produces better results. We conducted a user study to compare the performance of the relevance feedback methods with real users and compare the results with the findings from the tree analysis. This comparison between the simulations and real user behaviour indicates that the Bayesian algorithm, coupled with the sampled display, is the most effective.

‘Pathological demand avoidance’ (PDA) describes a pattern of difficulties increasingly recognised as forming part of the autistic spectrum. Although clinical reports suggest that children with PDA are likely to experience considerable difficulties in education, their educational experiences have not yet been explored in any systematic way. In the current study, 42 parents of children with PDA completed a questionnaire about their child's educational experiences. Parents' responses indicated that this group of children displays high levels of problem behaviours in school, and receives corresponding high levels of special educational need support and professional involvement. Despite this support, the group had experienced high rates of exclusion and placement breakdown, with only 48% now in mainstream education. Parents reported relatively high satisfaction in their children's educational placements, with success defined by parents in terms of child outcomes, school characteristics and PDA‐specific factors. Findings are discussed with reference to what is known about the educational experiences of children with more typical autism spectrum conditions and in terms of the implications for the inclusion of this group of children with complex needs.  相似文献
