The role of further government intervention in Australian international education

Trade in Australian education services has expanded rapidly over recent years. The sector is the third largest exporter of Australian services. In 2001–2002, exports of education were about $A 4.2 billion. Government assistance to the sector includes export market development, regulation of education standards, and funding education activities; university research and development, for example. This paper examines the case for further government intervention in the export of education, and the appropriate forms of assistance if further government intervention is justified. The paper predominately focuses on assisting higher education exports because this activity dominates education exports.

Introduction to the special issue on genes, environment, and reading

This introduction to the special issue on Genes, Environment, and Reading presents an overview of the background for behavior- and molecular-genetic research on dyslexia and individual differences across the normal range. The general methods, questions addressed, and selected results are summarized for each of the papers in the order of their presentation in the special issue. Concluding comments reflect on the influence of environmental range on estimates of genetic and environmental influences, and the future of behavior- and molecular-genetic research on reading.     

安徽省税收负担与经济增长协调性的实证研究(1978-2006)

通过计量经济学的多元回归模型、协整检验和格兰杰因果关系检验对1978—2006年安徽省的税收负担和税收弹性等问题进行定量分析,结果表明经济总量和财政收入之间存在一种长期的均衡关系,但财政收入变动对GDP变动没有显著影响;财政收入变动是财政支出变动的原因,而财政支出变动不是财政收入变动的原因,说明安徽省财政收支总体上还是一种"量入为出",而非"量出为入"的结构。     

A Process Approach to Community-Based Education: The People’s Free University of Saskatchewan

On the basis of insights provided by Whitehead and John Cobb, I show how the People’s Free University of Saskatchewan (PFU) is a working model of free, open, community-based education that embodies several characteristics of Whitehead’s philosophy of education. Formed in opposition to the growing commercialization at the original “people’s university,” (the University of Saskatchewan) the PFU has spawned distinctive ideals of its own. The PFU reflects Whitehead’s belief in the importance of shared knowledge fostered by community-based education, the value of abstract and practical knowledge, and the power of the imagination to establish a community of learners capable of acting freely together.

清教思想在白兰和珠儿关系上的体现

纳撒尼尔·霍桑的著名小说《红字》自 185 0年问世以来 ,无疑取得了很大成功。霍桑生活的时代 ,正值美国历史上清教主义盛行的时代 ,因而清教主义思想在这一小说中有所体现。本文旨在分析清教思想在白兰和珠儿关系上的体现 ,提出白兰和珠儿是一个紧密联系的整体 ,白兰的道德升华过程就是对珠儿的抚养过程。白兰正是在对珠儿的抚养过程中 ,实现了自己从“通奸”向“天使”的转变。与此同时 ,珠儿的象征意义在这一过程中是变化的 ,这变化是同白兰的道德升华过程紧密联系的     

稀土元素对黄粉虫生长繁殖的影响

用含不同剂量稀土的饲料喂养黄粉虫，发现在每公斤饲料中添加100mg氧化镧可使黄粉虫的一些重要的生理指标发生明显的变化：①在生长力方面，幼虫的生长速度显著加快，幼虫的存活率有所提高；②在繁殖力方面，雌虫提前两天产卵，雌虫的产卵期缩短了5天，雌虫的产卵量显著提高，实验结果还表明稀土在黄粉虫体内的蓄积量很低，稀土处理50天的幼虫主要营养成分含量无显著变化．     

Models and Paradigms in Kuhn and Halloun

In Modeling Theory in Science Education, Halloun (2004) adopts the word ‘paradigm’, but his use of the term is radically different from that of Kuhn. In this paper, I explore some of the differences between Kuhn’s paradigms and Halloun’s paradigms. Where Kuhn’s paradigms are public, community-defining exemplars of practice, Halloun’s paradigms are private, individualized ways of thinking. Where Kuhn writes of the paradigm shift as a revolutionary, vision-altering conversion experience, Halloun writes of a gradual evolution from one way of thinking to another and an easy back-and-forth switch between paradigms. Since Kuhn’s paradigms are self-enclosed and incommensurable, there is no objective standard by which one paradigm can be shown to be superior to the other. But Halloun uses ‘viability’ as a standard for paradigm choice. Underlying all of this is the more basic question of whether the history of science is an appropriate metaphor for student progress in the classroom. I conclude with some brief thoughts on this question.
