信息时代中 ,由于网络在查找资料上的方便与快捷 ,已经对当前高校的院系资料室形成较大的冲击 ,资料室存在的合理性因此受到质疑。然而 ,笔者认为网络可以取代的只是资料室的显性功能 ,而资料室本身所具有的隐性功能则是网络所无法替代的。本文主要以资料室的隐性功能的阐释为出发点 ,认为环境与交往是资料室隐性功能发挥的重要机制 ,进而剖析高校院系资料室隐性功能的具体体现 相似文献

The advent of thousands of Usenet groups on the Internet, covering a vast range of medical and welfare issues and ostensibly devoted to the mutual social support of participating members, has raised the potential for the development of new forms of 'virtual' health care. This article critically analyses the use by people with diabetes of one such Usenet group. It seeks to establish, first, the extent to which such a site provides some demonstrable measure of social support to its participants. This is approached by undertaking a structural analysis of the site to identify the extent of usage, and the nature of supporting interventions using a fivefold classification (instrumental, informational, esteem and social companionship and other). Second, the article attempts to identify any disparity between the lay health-knowledge in evidence and biomedical opinions proffered by the use of a panel of consultant diabetiologists. The results of the analysis suggest that the diabetes newsgroup provides an example of an active forum for largely well-informed participants who routinely use the media as an aid to the reflexive management of their medical condition. It also raises the prospect of a renegotiated relationship between medical knowledge and lay experience based upon shared learning 相似文献

Trends in online media relations: Web-based corporate press rooms in leading international companies
An analysis of 120 corporate websites from Denmark, France, Germany, Norway, Singapore, Spain, the United Kingdom and the United States reveals, for the first time, international results about the implementation and use of virtual press rooms. This article shows the importance that large international companies attribute to Web-based media centers to achieve organizational objectives and to meet journalists’ demands for information and audiovisual resources. The study also shows, however, that most press rooms are far from being complete, efficient, easy-to-use, reliable and updated on a daily basis. In fact, there is not a single country from those analyzed that consistently stands out from the rest. In most of them, good results in certain areas coexist with significant shortcomings in others, resulting in some cases in poor press rooms that may not achieve the desired public relations objectives. 相似文献

The diaspora of peoples whose origins were in the Indian subcontinent (South Asia) and who are now living in Western countries (especially the U.S. and UK) provides an interesting example of processes of negotiation of new hybrid cultures and identities, using new technologies, such as the Internet, and older technologies like the video player, cable or satellite television, radio, and telephone. These developments may require a revision of the classic sociological picture of assimilation as a zero sum model of acculturation, in which the acculturation of immigrants and their children involves the gradual replacement of their ethnic culture by that of the culture of the host nation. The electronic media, in the context of policies of multiculturalism, may lead to an accentuation of religio-ethnic differences. Contrary to previous assumptions, middle-class immigrants may be more inclined to resist cultural assimilation than their lower-class counterparts. 相似文献

We examine how people's different uses of the Internet predict their later scores on a standard measure of depression, and how their existing social resources moderate these effects. In a longitudinal US survey conducted in 2001 and 2002, almost all respondents reported using the Internet for information, and entertainment and escape; these uses of the Internet had no impact on changes in respondents' level of depression. Almost all respondents also used the Internet for communicating with friends and family, and they showed lower depression scores six months later. Only about 20 percent of this sample reported using the Internet to meet new people and talk in online groups. Doing so changed their depression scores depending on their initial levels of social support. Those having high or medium levels of social support showed higher depression scores; those with low levels of social support did not experience these increases in depression. Our results suggest that individual differences in social resources and people's choices of how they use the Internet may account for the different outcomes reported in the literature. 相似文献

逻辑演算与形式化方法 总被引:3,自引:0,他引:3
逻辑演算对推理形式有效性的研究 ,比传统逻辑更抽象、更严格 ,其原因是形式化方法的运用。形式化方法包括构造形式系统 (语法的 )和对该系统进行解释 (语义的 )两个阶段。以一阶逻辑演算KL 系统为例 ,形式化方法的前期阶段 ,又包括符号化和系统化两个步骤 :符号化是用特制的人工语言符号将推理形式或演绎关系公式化 ;系统化是在符号化基础上构造形式系统 ,即用系统给定的公理和变形规则推导出一系列定理的形式证明系统 ,这是逻辑演算的主要内容。形式化方法的后期阶段或第三步骤是对系统的解释 ,也称模型化。经过解释 ,该系统的符号、公式有了内涵 ,从而就有了更普遍的适用价值。纯形式的逻辑演算的性质、意义和作用也因此变得十分清晰 相似文献

《论语·学而篇》第十六章"不患人之不己知,患不知人也",传统的解释是"不着急别人不了解自己,却着急自己不了解别人",这未能切中孔子原意.从论语的不同注本看,更重要的是从孔子和《论语》的一贯精神看,该章应解释为"不要担心别人不了解自己,而应担心自己没有东西让别人了解". 相似文献
