Universities are at a pivotal point in their history and are undergoing dramatic changes. One of the more significant of these changes is the move towards instrumental programmes of learning, as manifest for instance in workplace and work-based learning. This paper argues that this trend threatens the existence of the liberal university, where knowledge is pursued predominantly for its own sake. The paper identifies four dominant discourses in higher education and suggests that these discourses co-exist with one another, and are sometimes dominant, at other times recessive. It argues that the trend to a post-industrialised labour market has seen the emergence of a vocationalised discourse in higher education, which stresses the instrumental at the expense of the liberal.  相似文献

In this study blood samples are taken from two groups of people, one that has direct exposure to pesticides (agriculturists & public health workers) the second group, which has indirect exposure to pesticides through food chain. The objective of our investigation is to analyze the blood of the patients with minimum health complaints and skin diseases for the residue of the banned organochlorine pesticides DDE and BHC using Gas Chromatography. High concentrations of both BHC&DDE were observed in the serum samples of the people who had direct exposure to the pesticides, namely agriculturalists and public health workers with few exceptions. The pesticide residue concentration in serum ranges from 0.006 to 0.130 ppm for BHC and 0.002 to 0.033 ppm for DDE. Significance of this study reveals that the presence of these banned pesticides in human serum.  相似文献

This article gives both the pedagogic and scientific thinking that guided the construction of a classroom role-play—The Great Evolution Debate. This role-play is about the publication of Darwin's The Origin of Species, which is supposed to be on trial for blasphemy. Historical characters are used to show the range of ideas which were current at that time. The literature on learning history, and on learning about the nature of science, is discussed, leading to an examination of historical empathy as a classroom objective. The reasons for including the various characters in the role-play are explained. The exercise has been used by 15 to 16-year-old students in British high schools with considerable success, and some tentative findings about learning from role-play are drawn from its observation.  相似文献
