This article discusses relevant literature on the potential benefits of sport, recreation, and leisure, and how these benefits relate to rehabilitation of juveniles. Many professionals involved in juvenile rehabilitation believe sport and recreation are beneficial adjuncts to treatment programming; however, it can be difficult to structure sport and recreation in ways that directly correspond to treatment goals. The purpose of this article is to provide insights for professionals working with juveniles on how sport and recreation programming can be an effective means of helping to achieve rehabilitation goals. Attention is given to approaches, particularly the Teaching Games for Understanding model (Bunker & Thorpe, 1982), which can be used to effectively link recreation and sport to the rehabilitation process. 相似文献

颅脑损伤患者智能和记忆损害的相关因素研究 总被引:3,自引:0,他引:3
目的探讨交通事故所致颅脑损伤伤者的智能和记忆损害及相关因素。方法 统计分析成都市1999年1月1日至2001年12月31日间因交通事故造成颅脑损伤的652例伤者的心理测验、脑电图及脑影像学资料。结果研究组平均智商为77.85±15.97,27.9%的伤者智商低于70;51.9%的记忆商低于51。智力损害与文化程度、左颞叶损伤、≥3个脑叶损伤以及脑电图异常明显相关;记忆损害与文化程度、损伤和鉴定检查的间隔时间、脑于损伤、左颞叶损伤、脑电图异常明显相关。结论交通事故造成颅脑损伤的伤者多有不同程度的智力和记忆损害,且与左颞叶损伤、脑电图异常、文化程度、脑干损伤等因素有关。 相似文献

With new technically advanced methods and computers at our disposal, the efficient market hypothesis is once again being debated. At the same time, we are witnessing an unprecedented growth in both existing and new financial markets. These new markets are often in economies which have just recently embraced free market economics; we term these stock markets infant markets. Such stock markets are obviously not efficient in allocating the supply of savings to productive capital. We do not test whether or not these infant markets are informationally efficient, but instead examine whether and how they are becoming more efficient. We propose modelling the excess returns of individual securities using a multi-factor model with time-varying coefficients and generalised auto-regressive conditional heteroskedastic (GARCH) errors. If the markets are becoming more informationally efficient or the agents are learning, we would expect this to manifest itself as the time-varying coefficients becoming more stable as time increases. We test our model using data on four Bulgarian shares. First, we estimate an AR(2) model and a GARCH-M(1,1) model for the shares. Then, we estimated our AR(2) model with time varying coefficients and GARCH type errors. We find varying levels of efficiency and varying speeds of movement towards efficiency within our sample of four shares. 相似文献

The enzyme activity of phosphoglucomutase (PGM) has been investigated in red cell haemolysates from 142 individuals and compared to the sub-type as determined by isoelectric focusing. The 10 phenotypes showed significant differences in PGM-activity which indicates that there is a correlation between the level of activity and the isolelectric point of homozygotes. No indication of silent alleles or alleles with reduced activity was found in this collective. 相似文献

The Tax Reform Act of 1986 rewrote the federal income tax code, bringing it closer to policy professionals' vision of what constitutes an equitable and efficient income tax. Research on tax compliance suggests the law might have affected taxpayer compliance in three ways: by reducing opportunities to overstate deductions, by changing perceptions of fairness, and by altering tax liabilities. Changes in taxpayer perceptions, attitudes, and noncompliance intentions were examined in three bodies of survey data, each containing pre-and post-reform data from independent samples of the same population. The results show an improved normative climate for taxpayer compliance and point to both the feasibility and the importance of examining the effects of substantive tax policies on taxpayer perceptions, attitudes, and behavioral intentions. 相似文献

Acknowledging Spain's diversity, this article assesses the impactof nationalism, regionalism, and other factors on public opinionabout the country's young democratic institutions. Utilizingsurvey data, the analysis focuses on national and regional variationsin public preferences for central state institutions and federalistor other designs for state-regional relations. It concludesthat a strong base of support exists for the current democraticsystem and the institutions through which it is implemented.Nevertheless, some doubts remain about the basic state structureof central-regional relations. 相似文献
