Dynamic forces in multiport mechanics: Direct and Lagrangian formulations

Holonomic systems can be represented by a bond graph in which inertial variables are related to generalized variables using a multiport displacement-modulated transformer structure. It is shown that the part of the generalized forces due to inertial elements can be found either by direct calculation or by the operations of Lagrange's equations. Although no gyrators are needed for the representation, gyrational coupling may exist. Alternative representations may involve gyrators explicitly and it is possible to construct kinetic co-energy functions for these gyrators for use in Lagrange's equations.     

Inclusive education: a critical perspective

The Gulliford Lecture 2002 was given by Professor Geoff Lindsay, Director of the Centre for Educational Development, Appraisal and Research (CEDAR) at the University of Warwick. Professor Lindsay's lecture, on which this paper is based, addressed a number of key topics, including the development of inclusion and inclusive practices; models of special educational needs and disability; and the values that underpin our thinking about these matters. Basing his argument on the research evidence, Professor Lindsay provides a searching critique of prevailing notions about inclusion and of current approaches to research. His conclusions will be of interest to everyone concerned with the education of children and young people with special educational needs.     

Persistence of Attitudes and Values of NDEA Students-Two Years Post Institute

Eighty-two students who had been enrolled in year-long NDEA Counseling and Guidance Institutes were followed up for a two-year period concerning attitudes and values. Subjects were administered the Porter Test of Counselor Attitudes and the Study of Values. Students attitudes and values similar to those present at the onset of their program and similar to those present after they had been away from their program one year. Some differences were noted concerning end-of-institute responses. Changes occuring during the programs appear minimal. Since there were no differences indicated between the one- and two-year follow-up, one year might be a sufficient period for this type of investigation.     

Managing course design

Any complex activity, such as course design, which involves group work must be managed. In universities, where academics are not always familiar with managing, it is often unsystematic. A modest attention to management can help a project, and may pay dividends in the avoidance of waste, conflict, overruns of time or budget or other potential disasters. The author presents a comprehensive framework for the various aspects of managing that may be needed and offers an extended checklist.     

Racial Perceptions of Young Children: A Review of Literature Post-1999

It has been argued that intervention strategies designed to reduce racial prejudice in young children have been based on weak theoretical models of racial stereotyping and prejudice with little effect on the reduction of racial bias. This paper examines the social-cognitive and intergroup scholarship post-Bigler (J Soc Issues 55(4), 687–705, 1999), with an emphasis on the development of racial prejudice in young children. The purpose of this paper is not to argue for a particular theoretical approach, but to provide an overview of some of the important pieces of research. Findings indicate that social learning and cognitive development models need to be understood when implementing curriculum designed to reduce racist beliefs and attitudes in young children.     

关于建设高水平大学的思考

高水平大学的建设是一个较长期的过程,不仅要形成尊重学术和民主管理的氛围,还要以本科教育为中心,形成自己的特色;既要服务于国家和社会的需要,又要注意摒弃极端的功利主义倾向。在高水平大学建设中,大学办学自主权和政府宏观管理缺一不可。建设高水平的大学,校长是关键,学科建设和教师队伍建设是重中之重。     

课程改革与教学模式转变

新一轮基础教育课程改革以空前的力度和崭新的面貌令世人关注,要实现课程改革的预期目标,关键在于教学模式的转变。现行教学模式必须从教师本位向学生本位转变,从独白式教学向对话式教学转变,从封闭式向开放式转变,从传递接受式教学向以引导探究为主要特征的多样化教学转变。
