分析与实践:索尔蒂斯的公共教育哲学观

当前我国教育领域的改革和讨论越来越激烈,而教育研究和实践之间的"沟壑"仍然没有减缓,这种局面如何才能打破,教育专业人士如何参与到公众的讨论中,如何在大众的教育导向中发挥作用,这些都是当前亟待解决的问题.美国学者索尔蒂斯为我们提供了有益的启示.本文从他的"公共教育哲学"观出发,以分析和实践为线索,介绍这一思想形成的背景、基础和图景,寻找其对我国教育发展可能产生的影响.     

J2EE框架中EJB对存储过程调用的实现

存储过程可以降低应用服务器和数据库服务器之间的网络通信量,提高分布式计算的性能.EJB组件在J2EE框架中负责处理核心业务逻辑,与数据库交互频繁.EJB对存储过程的调用是J2EE关键技术之一.本文通过实例详细阐述了这一关键技术的实现过程.

Do University policies make a difference?

The purpose of this paper is to examine whether the technical universities have been more successful in facilitating the spillover and commercialization of knowledge. We compare the impact of technical and general universities on the performance of knowledge-based firms. Based on a unique data set consisting of publicly held high technology firms, the empirical evidence suggests that, in fact, firm performance is not influenced by the type of university. Technical universities do not have a differential impact on firm performance from more general universities.     

J/ψ和ψ（2S）衰变中η和η′混合的研究

基于不同实验组给出的J/ψ,ψ（2S）→VP的分支比,我们对赝标量介子η和η′混合的可能性进行了研究.发现如果只计及夸克组元,拟合给出的混合角分别为（-14.04±2.37）°和（-11.99±10.46）°;而如果η和η′同时含有胶子组分,则η可能只有轻的夸克组成,η′中的胶子组分可能为Zη2′=0.30±0.24.

Immigration and student achievement: Evidence from Switzerland

This paper investigates empirically whether immigrant students in Switzerland perform poorly compared to their native counterparts and provides some explanations. Using a national sample of the 2000 PISA (Programme for International Student Assessment) database, we first analyze the impact of immigrant status on pupils’ achievement. We find a negative and significant impact of immigrant status on test scores in reading, mathematics and science literacy, even after controlling for a set of characteristics. We then decompose the observed reading score gap between Swiss and immigrant students to identify whether gaps in endowments explain test score differences along the distribution. Lower endowments explain most of the achievement gap in reading between Swiss and second-generation immigrants. However, lower returns explain around one quarter of the achievement gap between Swiss and first-generation immigrants for the weakest pupils.     

中外女篮主力后卫队员攻防技术对比分析--以第30届伦敦奥运会为例

运用文献资料法、录像观察法、数理统计法、对比分析法,对第30届奥运会中外女子篮球主力后卫攻防技术指标进行研究分析。结果表明：与世界强队相比,中国女篮的主力后卫队员在投篮技术运用、篮板球、抢断球、盖帽与组织技术等方面有待提高。而且当面对对手压迫性防守时,进攻投篮命中率较差,并没有充分发挥外围的进攻优势。     

Turning scientific and technological human capital into economic capital: the experience of biotech start-ups in France

This paper examines how scientific and technological (S&T) human capital is transformed into financial capital through the creation of firms by scientists. The analysis is based on a database describing the positions held by 132 founders from 62 French biotech SMEs. It shows that star scientists engage in highly risky but also valuable firms. Less famous scientists must develop their human capital rather than valorising a stock. The paper concludes by pointing to three paradoxes concerning the commitment and compensation scheme of star scientists and the managerial position of less known scientists.
