This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors. 相似文献

High technology is a concept much in vogue in OECD countries, for it is a symbol of an “advanced” economy. This paper looks at why and how the concept and its indicator acquired such fame. It explains that the reason has to do with the fact that the indicator emerged in the context of debates on the competitiveness of countries and their efforts to maintain or improve their positions in world trade. The first part looks at the early statistics behind the indicator (R&D/sales), statistics developed in official analyses of industrial R&D surveys before the 1950s. The second part traces the evolution of the R&D/sales ratio in the 1960s through its use as an indicator of research or technological intensity. The third part discusses the internationalization of the indicator via the OECD. 相似文献

孵化器与风险投资融合模式研究 总被引：1，自引：0，他引：1
近加年来,世界各国为了推动高新技术产业的发展,普遍采用孵化器与风险投资融合的模式.孵化器和风险投资在形成的背景、追求的价值、主要的服务功能、关注的空间和时间形态上有所不同,但在发展方向、运行模式、投资领域的专业化和退出方式上存在着很多的共同点,并且在项目源、管理、资金和政策上存在着很强的互补性,两者的融合将是"双赢"或者"三赢"的结果,融合非常必要,彼此都有融合的利益和风险.因此,二者的融合成为一种必然的趋势,也必定能促进风险投资和孵化器的共同发展,寻求它们之间的融合机制也变得越来越重要. 相似文献

This paper examines the category of "Woman" within the metastructure of a system of knowledge organization. We trace the subject scheme used to list books about women in a standard bibliographic guide over the first three-quarters of the twentieth century.Building on the feminist critique of subject representation, our analysis documents how the category was continually constructed over time, providing evidence of multiplication, isolation, and confusion in the process. The outcome is a framework that fails to capture the complex nature of knowledge about women and conceals relationships to the larger body of knowledge. The case of this legacy system exemplifies problems associated with representing the complexity and integration of knowledge and provides a basis for considering the potential residual impacts of current information organization and navigation systems. 相似文献

The effect of administration of N-acetylcysteine on ethanol and paracetamol induced hepatotoxicity was studied both biochemically
and histopathologically in experimental rats. The liver samples taken after twentyfour hours from the paracetamol administered
normal and alcoholic animals showed high degree of necrosis and related pathological changes. In the N-acetylcysteine treated
alcoholic rats and in the N-acetylcysteine pretreated paracetamol administered rats, the liver cells showed very little change
and appeared almost normal as evidenced by the histopathological studies. The activities of serum transaminases and phosphatases
were also high both in the alcohol treated and in the paracetamol administered animals. N-acetylcysteine treated animals partly
restored the serum transaminase and phosphatase activities, and the activities of the antiperoxidative enzymes. There was
also significant change in the serum and tissue lipid levels, and in the concentration of the tissue lipid peroxidation product-malondialdehyde
in both the alcohol treated and in the paracetamol administered groups. N-acetylcysteine treatment brought the serum and tissue
lipid levels, and the tissue malondialdehyde content towards normal. 相似文献

维修打印机之前需要对打印机出现的问题有一些了解。打印机出现问题后，首先是利用打印机自检系统进行检测，通过打印机自带的指示灯或者是蜂鸣器的声音来加以判断：其次，可以进行线路观察，看部件是否正确工作，针对不同的故障情况锁定相关的部件，再确定存在问题的部件；再次，可以使用测试法，进行测试页打印或者局部测试打印机内部件，查寻故障原因。 相似文献

Contrary to the "retro" image often awarded them, and despite their continuing enthusiasm and responsibility for the organization of printed materials, librarians are upbeat about the prospects of an information society driven primarily by electronic technologies, but in which libraries can play an important part. Public librarians detect a natural correlation between the historic democratic mission of their institution and the increased accessibility made possible by digitalized sources. The library community's acceptance of the information society idea as a "given" social phenomenon supports discourses that play down historical continuities and herald the dawn of a new age. Such discourses ignore or reject historical evidence that points to the existence of past information societies, revolutions, and infrastructures defined, in part, by the operation of indirect surveillance, constituted by the bureaucratic information systems of modernity. Victorian Britain serves as a good example of an early information society, to which public libraries, themselves micro-information societies, contributed significantly. The role played by public librarians in the Victorian information society, illustrated in this article by evidence drawn from the contemporary library press, is seen in their preoccupation with the surveillance and ordering of knowledge; their adoption for library operations of the businesslike, bureaucratic procedures described recently by business historians; and their panoptic tracking of users and their activities. 相似文献
