Opportunities on the Web: a role for information professionals, using the development of the BMA Library Online Service as a case study

The paper considers how attributes and skills fundamental to the information profession may be applied to the development and management of Web-based services and resources. It also looks at the need for the acquisition of new skills as part of a continuing professional development programme. The report considers the changing role of the Webmaster and the implications this might have in terms of the role of information professionals. To offer a practical example, from within the healthcare sector, the article goes on to describe the development of BMA Library Online. This is the BMA Library's own suite of Web-based information services and resources for personal members, institutional members and staff. The library's own Web team has been responsible for the development and maintenance of BMA Library Online. To conclude, the paper looks forward to future possibilities for information professionals as Web developers and at how this might be influenced by changes in the Webmaster role. It is crucial that skills and expertise are shared as the roles that go to make up a Webmaster or Webmaster team continue to merge and evolve, and with the possible wider distribution of provision of Web content within organizations.     

Interaction of wrestling shoe and competition surface: effects on coefficient of friction with implications for injury

The purpose of this study was to determine whether there is a significant difference in the co-efficient of friction (Fc) between old versus new wrestling shoes and mats and to investigate the effect of perspiration. Fc was measured by dragging a weighted shoe over a wrestling mat surface and measuring the vertical and horizontal forces produced. Three different shoe conditions were assessed over two mat types for both wet and dry conditions for a total of 12 conditions. To simulate the wet condition, saline solution was smeared over the surface of the mat. There was a significant effect of shoe, mat, and wet/dry conditions. In addition, significant interactions of shoe by mat, shoe by dry/wet, and mat by dry/wet were observed. Overall, Fc was 36% higher for the new wrestling mat compared to the old wrestling mat. Application of the saline solution reduced Fc by 14% compared to the dry condition. Comparison of the mean Fc for all three shoe types revealed the Fc for the older design shoe was 23% to 28% lower than the brand new shoe and the worn newer design, respectively. A high Fc, such as in the new mat/new shoe combination, has the potential to increase the risk of knee and ankle injuries by fixing the foot more securely to the ground.     

摄影和摄象技术三维直接线性变换(DLT)再现精度的比较

记录人体运动的准确性在很大程度上取决于记录方法的精确度。计算出的物体运动学的数值,主要依赖对物体运动记录的准确性。人体运动的生物力学分析经常需要对16mm摄影或摄象技术记录的内容进行分析.由于摄象具有成本低,使用方便,处理时间短的特点,使摄象技术比摄影更具吸引力.然而必须考虑摄象精确度是否与摄影标准相同.要使摄象技术合法地进入人体运动分析领域,摄象记录的精度必须达到摄影记录的     

五种课程概念——它们的思想根源及其课程设计的思想(下)

社会改造式课程 这种课程方向竭力强调教育和课程内容在整个社会环境中的作用。社会改造主义者总是强调社会需要胜过个人的需要;全面的教育目的要以整个经验为依据,而不是根据立即发生的过程来确定。他们考虑的首要问题是社会改革和承担对社     

五种课程概念——它们的思想根源及其课程设计的思想(上)

长期以来,美国教育界对于学校课程的研究存在着五花八门的思想。斯坦福大学艾斯纳和瓦伦思两位教授所写的这篇论文是在全面分析美国课程研究的各种不同观点的基础上形成的。他们归纳的五种课程方向虽然不能代表美国课程概念的全部,但确是几种主要的。多少年来,这几种课程方向一直不同程度地影响着美国的课程建设。 这几种课程方向之间的分歧由来已久。在本世纪六、七十年代美国的课程研究和课程辩论中,它们之间的分歧得到了最充分的表现。众说纷纭,各持一端,争论十分激烈,许多问题难于得出结论;主要问题就在于没有弄清课程概念上的分歧。艾斯纳和瓦伦思研究了大量的课程文献,发现了课程方向上的主要分歧。他们挑选出一批有代表性的论文,于1974年编辑、出版了一本论文集,书名《课程概念的论战》。其目的在于帮助课程专业人员和有关人士分清几种主要课程方向的界限,从那些不同的课程类型中得到启示。这里译出的是他们为该书写的导言。 这篇导言在美国教育界有一定的影响。他们编辑的那本论文集,虽然已经出版了十年,仍然受到美国教育界的重视,许多教育学院的课程教学系仍然把它列为博士学位研究生的必读书目。因此,我把这篇导言译成中文,供我国教育工作者研究。自然,由于阶级的局限,本文作者不可能运用马克     

基础科学组

科学事关基础知识的广泛探索,而这种探索受到人们对其所生活世界的好奇心的驱使。求知欲是人类的天性,而通过基础研究为此作出贡献是人类的责任。基础科学即数学、物理学、化学和生物学,为一切科学研究和技术开发提供了必不可少的工具。资助这些基础科学确实是社会对未来可能做的最佳的投资。工业化国家目前的资助水平约占国民生产总值(GNP)的0.3—0.4％,大多数发展中国家甚至更低。到1995年,合理的目标是把这项预算翻一番,并且期望经过一个较长的时期,这方面的投资必定能够得到数倍的收益。今后向第三世界科学技术项目提供的开发资金,应该包括资助基础科学研究的独立部分。     

电子时代的图书馆和图书馆员

F·W·兰卡斯特,美国伊利诺大学情报学和图书馆学研究生院教授,著述颇丰,多次获奖。《电子时代的图书馆和图书馆员》一书于1972年出版,1974年第二次印刷。这本书预测了图书馆的未来,认为到2000年,人类会进入无纸社会,图书馆最终消亡,图书馆员作为情报技术专家活跃于未来的电子时代。作者的目的在于激励图书馆员对前途树立信心,认真估价图书馆和图书馆员在急剧的社会变革和技术革命浪潮中的作用,要适应新情况,赶上时代潮流,促进社会发展。这里刊载的是这本书内容的缩编,读者可以大致了解兰卡斯特的观点。
