裴斯泰洛齐体育教育思想研究

裴斯泰洛齐是19世纪瑞士著名教育家,他的教育理论在经历了中国化的传播与发展之后,对我国教育理论产生了重要影响,但对我国学校体育产生的影响还未能很好地揭示。文章对裴斯泰洛齐有关学校体育观表述如下：儿童体育教育是实施儿童德、智、体、劳和谐教育的一个重要内容;儿童体育教育应符合儿童自然的运动天性;儿童体育教育应循序渐进、区别对待;家庭是儿童体育教育的重要场所。根据以上观点,提出了在未来中国学校体育改革与发展中值得借鉴的几个方面：（1）进一步加强体育的育人功能,强化体育与德育、智育的联接,以提升学校体育在学校教育中的地位与作用;（2）重视家庭教育和幼儿教育,开发婴幼儿体育,加强婴幼儿的身体锻炼,打好婴幼儿健康身体的基础;（3）儿童的体育教育必须符合儿童运动的天性,遵循循序渐进原则,按难易、分级分阶段进行,符合儿童学生成长特点;（4）重视体育教学的直观教学法,提高儿童体育教学的成效。     

《汉书·艺文志》之“小说”与中国小说文体确立

“小说”一词 ,始见于《庄子》,但对小说文体进行界定和总结的首推汉代刘向、刘歆。浓缩刘氏父子校出成果、删《七略》之要的《汉书·艺文志》不仅首次确定了小说文体术语 ,著录了小说作品 ,也说出了小说出自民间 ,具有故事性、虚构性的特征 ,标志着中国小说文体在理论上正式确立并开始步入自我发展的正史时代。那种主张将自《汉书·艺文志》开始的目录学“小说”概念与自唐传奇开始的所谓文学小说概念区别开来 ,将唐传奇以前的小说视为中国小说的前史状态的观点 ,值得商榷。

劳伦斯小说创作艺术中的现代主义象征手法简论--劳伦斯小说创作艺术研究系列之一

二十世纪英国著名小说家D·H·劳伦斯是一位才华横溢且颇为引起人们关注和争议的文学大家.在其文学作品中,他善于运用现代主义的象征手法,为其小说创作服务,从而刻画出一个个寓意深邃,栩栩如生的人物形象.本文拟从其象征主义手法,在其几部主要小说作品中的灵活运用及其表现特点等方面略作阐述,旨在能使我们更好地理解其作品中的象征意蕴,更好地理解和欣赏其小说作品,深刻理会其小说的内容和主题及深刻的社会批判意义.     

BX_3与C=C之间p-π作用的量子化学研究

用量子化学计算方法对BX3(X=H,F,Cl)与C‖C之间通过p-π作用形成的复合物进行了研究.计算结果表明,各复合物中BX3均位于π键的上方,并且偏向于氢原子数较多的碳原子一侧.BH3与C‖C的作用是由π键中的电子通过向B的空p轨道转移而形成,但BF3和BCl3与C‖C的作用只是通过微弱的分子间作用力结合,复合物的形成使分子的振动光谱随作用的强弱而出现一定的红移现象.     

金属催化H2O2环氧化烯烃的研究进展

近年来，H2O2被用来作为氧源是因为其合理的稳定性，迅速有效性，廉价经济和绿色环保(副产物只有水)。H2O2与廉价的、相对无毒的金属催化剂相结合的环氧化系统。在廉价生产和具体合成研究上具有很重要的意义。综述了简单金属盐类、金属卟啉类配合物和金属Salen类配合物以H2O2为氧化剂催化环氧化烯烃的研究进展。     

Who benefits from student aid? The economic incidence of tax-based federal student aid

Federal benefit programs, including federal student aid, are designed to aid targeted populations. Behavioral responses to these programs may alter the incidence of their benefits, a possibility that receives less attention in the literature compared to tax incidence. I demonstrate the importance of benefit incidence analysis by showing that the intended cost reductions of tax-based federal student aid are substantially offset by institutional price increases for a sample of 4-year colleges and universities. Contrary to the goal of policymakers, I find that tax-based aid crowds out institutional aid roughly dollar-for-dollar. Unfortunately, it is not clear how institutions utilize these captured resources, so that the ultimate incidence of the programs is uncertain.     

Funding higher education and wage uncertainty: Income contingent loan versus mortgage loan

We propose a simple theoretical model which shows how the combined effect of wage uncertainty and risk aversion can modify the individual willingness to pay for a HE system financed by an ICL or a ML. We calibrate our model using real data from the 1970 British Cohort Survey together with the features of the English HE financing system. We allow for individual heterogeneity by considering different family backgrounds and occupations. We find that graduates from poor families, males and graduates working in the private sector are more willing to pay to switch to an ICL. Using the UK Labour Force Survey we evaluate the distributive effects of our model. We compute the repayment burdens and taxpayer subsidies for average, low and high earnings graduates. The results confirm the important insurance benefits of an ICL compared to a ML, with lower burdens and higher subsidies for poorer graduates.     

Do tuition fees affect enrollment behavior? Evidence from a ‘natural experiment’ in Germany

This paper uses the introduction of tuition fees in seven of the sixteen German states in 2007 as a natural experiment to identify the effects of tuition prices on enrollment probabilities. Based on information on enrollment decisions of the entire population of high-school graduates between 2002 and 2008, I find a negative effect of tuition fees on enrollment behavior. The effect is larger than in existing studies for European countries, but of a similar magnitude as effects identified with U.S. data. A potential spill-over effect of the policy intervention to the comparison group is accounted for by using the estimation results to calibrate a structural model of the enrollment decision.
