Problem-solving in teaching/learning packages for Technology

In the project Technology in Secondary Education: Problem-solving in Teaching/learning Packages, two experiments regarding a construction problem and an explanation problem were conducted, in which two variants of a teching/learning package (strongly structuredvs. weakly structured) were compared. Only with the strongly structured instructional variant of the package for the explanation problem did the pupils come to a quick solution of the problem. In both experiments, the factors that influenced the problem-solving processes of the pupils were investigated. The results are of importance for curriculum developers and the authors of teaching/learning packages for Technology but further research into the factors influencing the problem solving process of pupils is necessary.     

论养老基金平衡机制--基于辽宁试点模式对养老基金平衡的透视

我国处于转轨中的养老模式面临着人口老龄化和转轨成本的双重压力，为此，2001年7月开始在辽宁省进行社保改革试点。本将以试点模式为研究起点，并将养老基金平衡剖析为两个收支平衡：一是横向平衡，二是纵向平衡。就横向平衡而言，笔认为难关的突破在于强化政府的社会保险责任，而纵向平衡的难关在于基金收益率。为此，本提出一些拓展性的社保改革思路，并认为在此基础之上养老基金的平衡是可以实现的。     

Issues in decentralizing the provision of education

This paper analyzes some of the problems that arise in decentralizing education to the private sector. We concentrate on the difficulties that result from the heterogeneity of students and competition among schools in a location setting. We analyze two main issues, the resources expended by schools and the mix of students in schools, and report on results for two others, the location of schools and their number. For each of these, we investigate the extent to which decentralizing the provision of schooling results in an efficient allocation of resources, and consider the use of vouchers to improve the situation. Our analysis draws on elements of three distinct methodologies: the theory of clubs, location theory, and the theory of monopolistic competition. We find that private schooling will typically be inefficient, but that inefficiency may sometimes be corrected by appropriately designed vouchers.We would like to thank Olivier Debande, Jean-François Wen, two anonymous referees, and seminar participants at the 1st meeting of the Canadian Public Economics Study Group and the 51 st congress of the International Institute of Public Finance for helpful comments.

大股东资金占用与审计师的监督

本文研究审计师对大股东占用上市公司资金行为的监督作用。通过对1997年到2002年间的上市公司进行分析,我们发现随着大股东资金占用程度的加大,审计师更加倾向于出示非标准意见。在大股东占用资金最多的10%的公司年度中,审计师出示非标准意见的概率高达近50%。在控制了其他影响审计师意见的变量以后,大股东资金占用程度仍然是决定审计意见的一个非常显著的因素。这说明我国的审计师对中国资本市场出现的大股东资金占用问题有一定的认识,并且将其反映到审计师意见中去。我们进一步的分析发现: (1)被审计师出具了非标准意见的公司,其大股东占用资金反而更加持续。这说明审计师意见对公司的监督意义不大,公司并没有因为审计师的意见而减轻占用程度。(2)被审计师出具了非标准意见的公司,其大股东占用对未来的股票收益的负影响与其他公司并没有区别。这说明投资者对审计师的意见并没有给予足够的重视。本文的研究结果说明,审计师对大股东盘剥中小股东的现象进行了监督、对大股东资金占用严重的公司出示了更多的非标准意见,然而这些非标准意见并没有引起各方面的重视,一方面公司的治理并没有改善,另一方面投资者也没有因审计师的意见而避免更多的损失。     

论学科交叉路径及趋势

学科交叉是高等学校新学科生长点产生的源泉，是获得原创性科学成果的重要途径。高等学校应大力提倡跨学科研究来推进不同学科的交叉、融合与渗透，以实现学科建设的跨越式发展。     

不同融资制度下的金融中介发展

在任何一种经济中都需要建立一种金融机构与证券市场能够共同发挥作用的、完善的金融体系。但是,考虑到各种经济制度建立基础和发展历史与传统上的差异,以及金融体系与企业部门之间的关系不同,各国金融体系的架构并不需要保持完全的一致。本文从不同融资制度中金融中介的作用,探讨经济中金融中介的发展。     

Transferring and Transforming Technology Education: A Study of Norwegian Teachers’ Perceptions of Ideas from Design & Technology

What happens when educational ideas cross national and cultural borders? How do teachers respond to ideas originating in a different school system and a different national culture? This article reports on an empirical study investigating the transfer of ideas from Design &; Technology as a subject in England and Wales into Norwegian schools. A sample of teachers participating in a specific project on technology teaching inspired by this subject has been studied by means of interviews and classroom observation. Results of the study show that while some elements of Design &; Technology are adopted by the teachers, essential ideas of the subject are significantly transformed. Drawing on Barnes, (1992, Teachers and Teaching: From Classrooms to Reflection (pp. 9–32), The Falmer press, London) concept of teachers' professional frames for teaching, it is shown how specific aspects of the national and educational culture have had a considerable effect on?the teachers' interpretation of the nature of technology as a subject of teaching and its place in the curriculum. The study illustrates the importance of the cultural context in how educational ideas are interpreted, reshaped and realized in schools.     

The Influences of Teacher Knowledge and Authentic Formative Assessment on Student Learning in Technology Education

Students involved in holistic technological practice need to develop an understanding of technological practice outside the classroom and to participate in tasks set as close as practicable to actual technological practice. This paper investigates the context of assessment and its relationship to achievement and the importance of teacher knowledge to student technological practice. I argue that ‘out of context’ assessment tasks do not give an accurate indication of achievement levels of the children assessed. Introduced is the Model of Student Technological Practice, which identifies four constraints that influence student technological practice. A significant factor is teacher knowledge, as it impacts greatly on the quality of feedback given to students by their teachers. Timely teacher intervention and formative assessment feedback will alter student technological practice and should improve the students’ likelihood of developing successful outcomes.     

高校教材建设的"两难"问题及其解决对策

教材建设是高校教学基础性建设的内容之一,日益被国家和高校所重视。在教材的选用上,以国家统编教材为主和以高校自编教材为主的理由和趋势都比较明显。根据不同的办学类型实施各自的教材管理和发展战略,是解决选用教材时应以谁为主的关键所在。     

Mutual fund characteristics, managerial attributes, and fund performance

This study provides a comprehensive examination of recent mutual fund performance by analyzing a large set of both mutual funds and fund attributes in an effort to link performance to fund-specific characteristics. The results indicate that the hypothesized relationships between performance and the explanatory variables are generally upheld. After taking into consideration general market conditions and fund investment objective, the characteristic variables that relate to fund popularity, growth, cost, and management also explain performance. Finally, after controlling for survivorship and benchmark error as well as fund-specific factors, the results refute the performance persistence phenomenon.
