对政史双专业相关课程优势互补问题的思

政史双专业合并符合21世纪教育改革发展趋势、师范院校专科层次培养目标规定性及其学生的基本就业去向。政史双专业合并后,由于教学计划和课程安排的混乱、历史和政治教研室活动的各自为阵、教师知识结构的单一性等问题,影响了相关课程的优势互补。在科学删减某些课程、合理安排相关课程、调整教师知识结构和改进教研活动等方面提出解决的办法和途径,有助于政史双专业相关课程的合理设置及优势互补。     

Patenting and US academic research in the 20th century: The world before and after Bayh-Dole

The dramatic growth of patenting and licensing of publicly funded research by American research universities in the closing quarter of the 20th century has stimulated some of the highest-profile debates in science and technology policy today. The issue of what aspects of academic research should be public - and what private - lies at the heart of each of these debates. The movement of academic scientists into commercialisation of discoveries and inventions has been extolled by some as a new model of academic research, one which facilitates economic and social returns from universities. At the same time, this trend has been criticised by others as representing a socially inefficient ‘privatisation’ of academic research and as a threat to the ethos of science itself. This paper places these debates in historical context, with a review of changes in American universities’ patenting policies, procedures and practices throughout the 20th century, an assessment of the logic underlying the passage of the Bayh-Dole Act of 1980, and an overview of its effects on economic returns from university research.

Assessment of oxidative stress and antioxidant status in age related cataract in a rural population

Oxidative stress was assesed by estimating lipid peroxidation product (LPO) in the form of thiobarbituric acid reactive substances (TBARS), enzymatic antioxidants in the form of superoxide dismutase (SOD), catalase and nonenzymatic antioxidant vitamins e.g. vitamin C, β carotene and vitamin E in either serum or plasma or erythrocytes in 190 cases of age related cataract in the age group of 50–80 years. 190 cases were grouped into three morphological types namely, 73 cases of cortical, 77 cases of posterior subcapsular and 40 cases of nuclear cataract and values of LPO and antioxidants were compared with 78 cases of age matched healthy control groups. Plasma TBARS levels were cataract cases when compared with control groups. There were no significant differences in the erythrocyte levels of catalase and plasma levels of Vit E between cataract cases and control groups. No significant changes of parameters were seen among three different morphological types of age related cataract. The present study shows that the oxidative stress may play an important role in the age related cataract.     

Pre-service teachers’ attempts at debating contemporary issues in science education: A case study from Botswana

This paper constitutes an attempt to explore trends, issues and challenges that emerge when three different cohorts of pre-service teachers debate contemporary issues in science education at the University of Botswana. Apart from the author's experience of teaching the course, the impetus for this study also comes from a growing interest in the contemporary literature in the need for teachers who, in the context of globalization and knowledge economy, are ‘self-reforming’ through continually addressing the key issues of their profession. Unfortunately, the current situation is such that this burden of interrogation falls heaviest on teachers, despite their lack of skills in undertaking the task.     

Boys and machines: gendered computer identities,regulation and resistance

Students negotiate their masculine and feminine identities as students of information and communication technology (ICT) and computer users as they participate in specialist ICT courses and in other areas of their lives. As they negotiate these roles, they are established in relations of power and authority with the technology and with each other. Case study research relating to students’ experiences in specialist computer courses in a New Zealand secondary school reveals a complex and dynamic picture of identity construction and subjectivity. In constructing their personal identities as computer users, males and females experience the regulatory forces of gender relations while at the same time resisting stereotypes. Students make conscious and pragmatic decisions to pursue particular computing courses and paths as they balance their options in the realisation of their possible selves as computer users and adults in the world of work. These decisions signify regulation by and resistance to gendered power relations.     

略论革命的实践与毛泽东战略决策思想的关系

毛泽东是一位产生于中国本土的革命家、战略家。他所提出的一系列重要战略决策思想是其在漫长的革命实践中,努力将马克思列宁主义同中国实践相结合,通过不断总结经验教训提炼出来,再放回到实践中加以校验并证明是正确的指导思想。毛泽东自己也说＂是靠总结经验吃饭的＂。毛泽东关于农民和农民问题的理论观点,关于实事求是和全局观的观点,都是在实践中提出,并得到丰富和发展直至完备起来的。
