With so many options available for searching MEDLINE on the World Wide Web or as a component of an online service, evaluation criteria are suggested as a means of assisting librarians in determining the positive and negative aspects of alternative MEDLINE sites. A set of searches was utilized to systematically compare MEDLINE sites. Sites evaluated included Avicenna, America Online, HealthGate, PubMed, Medscape, and Physicians' Online. Some features used to evaluate these sites were: default fields; operators (default); access to MeSH; subheadings; stop words protected in MeSH; truncation; and stemming. This article will describe the group process used to arrive at the evaluation criteria, as well as some general conclusions which will help librarians in directing their users to a particular MEDLINE site. 相似文献

This chapter deals with a crucial component of our position, the presumption that there are objective grounds for preferring one thing to another within the various cultural institutions we deal with, that there are better or worse symphonies, soufflés and theories of the atom. The task of showing this is more urgent for some institutions than others. While philosophers can doubt anything, most people are persuaded of the objectivity of our efforts to comprehend the physical world and to weigh, count and measure accurately in many areas of human activity. Again, when we are faced with a choice among functional objects or processes, most people will admit that we can ground a preference for a knife or an exercise routine on objectively established facts: sharpness, or measurable increase in strength. Here, certainly, various conflicting desiderata may enter and make actual decisions more difficult — the sharpest knife may also be the most expensive; we may need to worry about its safety features; it may be ugly; and so on. But many will doubt that our judgements of comparative worth for non-functional objects such as paintings or sonatas can claim a similarly objective basis. We shall, therefore, concentrate our efforts on the most doubted areas, but will begin with the less contentious, where we think it is useful to draw attention to the genuine problems some philosophers have stressed, to show in fact that what we believe to be popular unconcern deserves to be somewhat ruffled. 相似文献

Defenders of high culture can be found invoking many and various allies. Many are, we think, out of place. These defences raise issues that we do not need to worry about or themselves create unnecessary difficulties for clarity of thought on these matters. In this chapter we will touch upon a number of such irrelevancies. We will begin by examining the assimilation of high culture to religion and religious concerns in the thought of Eliot and Scruton: this will allow us to indicate our stance on the place of religion in schools. We will then examine some psychological and sociological issues that Bantock has invoked in defending his secular vision of the role of culture, and conclude with Barrow's curious identification of culture with general intelligence. 相似文献
