中国体育史学史研究管窥   总被引:1,自引:0,他引:1       下载免费PDF全文
体育史学史作为一门新兴交叉学科,主要研究体育史学自身发展的历史。我国体育史学史研究涉及众多学科门类,形成了以体育学和历史学为主线,以哲学、经济学、管理学、社会学等学科为辅助的综合化研究理路。论及中国体育史学史研究的中心论题,这既来源于对我国体育史发展不平衡的归因分析,也涉及体育史学史建构的基本问题。我国体育有没有自身运动发展的历史脉络,关键在于探讨体育史学史研究命题缘起问题;我国体育的实践禀性是否拥有史学的居所,重点在于围绕中国体育史学史归属作出研判;当前体育学科发展史能否代表体育史全部,任务在于观瞻中国体育史学史的发展前景。  相似文献

Ethylene oxide is a gas produced in large quantities in the United States that is used primarily as a chemical intermediate in the production of ethylene glycol, propylene glycol, non-ionic surfactants, ethanolamines, glycol ethers, and other chemicals. It has been well established that ethylene oxide can induce cancer, genetic, reproductive and developmental, and acute health effects in animals. The U.S. Environmental Protection Agency is currently developing both a cancer potency factor and a reference concentration (RfC) for ethylene oxide. This study used the rich database on the reproductive and developmental effects of ethylene oxide to develop a probabilistic characterization of possible regulatory thresholds for ethylene oxide. This analysis was based on the standard regulatory approach for noncancer risk assessment, but involved several innovative elements, such as: (1) the use of advanced statistical methods to account for correlations in developmental outcomes among littermates and allow for simultaneous control of covariates (such as litter size); (2) the application of a probabilistic approach for characterizing the uncertainty in extrapolating the animal results to humans; and (3) the use of a quantitative approach to account for the variation in heterogeneity among the human population. This article presents several classes of results, including: (1) probabilistic characterizations of ED10s for two quantal reproductive outcomes-resorption and fetal death, (2) probabilistic characterizations of one developmental outcome-the dose expected to yield a 5% reduction in fetal (or pup) weight, (3) estimates of the RfCs that would result from using these values in the standard regulatory approach for noncancer risk assessment, and (4) a probabilistic characterization of the level of ethylene oxide exposure that would be expected to yield a 1/1,000 increase in the risk of reproductive or developmental outcomes in exposed human populations.  相似文献

国际扫盲趋势及其内涵的新发展   总被引:1,自引:0,他引:1  
李官  李劲松 《学术探索》2009,(1):132-137
本文根据国际扫盲教育的历史演进及其内涵的发展,把扫盲分为基础性扫盲、功能性扫盲和文化性扫盲三种,在总结和分析扫盲三个阶段的共同特点及存在问题的基础上,提出了“发展性扫盲”的概念,对当前国际扫盲及发展趋势进行了概括,从扫盲目的和评价标准、扫盲主体和对象、扫盲内容和形式三个方面对其内涵进行说明,提出了发展性扫盲的四个特点:基础性、动态性、终身性和全民性。  相似文献

Using conflict narratives reported by adolescents in grade 7 (mean age = 13.4 years), this study investigated the interactional properties and developmental functions of four types of aggressive behaviors: social aggression, direct relational aggression, physical aggression, and verbal aggression. A total of 475 participants from the Carolina Longitudinal Study ( Cairns & Cairns, 1994 ) were included. Results showed that the majority of conflict interactions involved more than a dyad. The use of social aggression (e.g., concealed social attack) was associated with more individuals involved in the conflict. Social aggression was primarily reported as an initiating behavior for interpersonal conflicts, while direct relational aggression was a responding behavior. Medium to high levels of reciprocity were found for physical, verbal, and direct relational aggression, whereas a low level of reciprocity was reported for social aggression. School authorities were most likely to intervene in physical aggression. The use of social aggression was associated with higher network centrality among adolescents. Developmental maladjustment in late adolescence and early adulthood was primarily predicted by physical aggression.  相似文献

论转型时期中国经济法的演进与发展趋势   总被引:1,自引:0,他引:1  
转型期的中国市场经济是由社会主义计划经济转化而来的市场经济,呈现出跨跃式发展的特征,是公有制多种实现方式基础上的市场经济,是处于从“身份与契约”的运动过程中的市场经济。转型时期的中国经济法特征:形成以政府、经营者、消费者三大主体为核心的经济法体系;自由演进和政府建构的有机结合;明显地表现出其阶段性、过渡性和中国特色;外来移植与本土资源的结合;传承与创新。  相似文献

DDT, DDE, and DDD have been detected at elevated concentrations in sediments and fish of the Yakima River, its tributaries and drainages. An assessment was conducted to evaluate the public health significance of eating fish from the river. This was accomplished by establishing a daily intake level of DDT for the population of greatest concern, and comparing this level to a tolerable daily intake. The most sensitive and highly exposed group was determined to be breastfeeding infants. Infant daily intakes of DDT, based on estimated mother's DDT-breast milk levels, were compared to a recommended tolerable daily intake. Results indicate that mothers who frequently consume Yakima River bottom-feeding fish could have breast milk DDT concentrations sufficiently high to expose their infants to levels above the tolerable daily intake.  相似文献
