SUMMARY The sites reviewed in this article represent only a small fraction of the consumer health information sites available on the Web and are intended to be a starting point for locating authoritative, reliable health information. The first part of this article focuses on evaluation, since this is an important component of using information, particularly information located on the Internet. The second part of the paper reviews consumer-related Web sites arranged by categories:Comprehensive Sites; Directories/Portals;Government Sites; Association Sites; Drug Information; Alternative Medicine; Nutrition and Food Safety; and Other Health Issues. 相似文献

In 2004 a collaborative, statewide outreach project in Delaware was undertaken where consumer health librarians were embedded in public libraries. In order to explore the effect of the embedded librarians on the quality of health information provision, unobtrusive reference visits were made to half of the public libraries in the state. The query “Do vaccines cause autism?” was posed to library staff; resources provided were recorded. In 67 percent of visits, public library staff provided authoritative health information resources. It appears the embedded librarians had a positive residual effect on the provision of authoritative health resources for addressing an ambiguous query. 相似文献

This study develops and tests an instrument useful for evaluating the quality of academic libraries on the World Wide Web (Libweb). By consulting authoritative criteria used for traditional print resources and Internet/Web resources, a set of 68 essential indicators was generated and later reorganized and reduced to 16 criteria through factor analysis. After a survey of library experts, the instrument's reliability was verified by analysis of variance. Furthermore, a regression model considering both the respondents' demographics and the quality criteria was applied to identify 11 significant factors, which were later reduced to eight factors. These eight factors represent the most salient and nonredundant criteria. Two instrument forms are suggested for prospective users to evaluate academic Libweb quality and to construct and maintain a good site. 相似文献

采用光沉积-液相化学法调节电子流向,构建了直接Z型TiO2/Ag/Ag3PO(4 )(TAAPO)光催化材料.通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线衍射仪(XRD)、X射线光电子能谱(XPS)、紫外-可见漫反射光谱仪以及光致发光(PL)光谱仪等手段对其进行表征,并对其在可见光照射下催化降解环丙沙星(CIP)的性能进行了研究.结果表明,当水体pH为3.0,催化剂分散浓度为0.3 g/L,CIP的初始浓度为15 mg/L时,光催化降解体系能够取得最佳的去除效果.在该组条件下,光照120 min CIP的降解率约为99%,并且在经历4个循环后仍然保持了良好的降解效果.在光催化降解CIP的过程中,主要反应活性物种为超氧自由基(·O2 相似文献

ABSTRACT Social technologies such as Weblogs, wikis, and social bookmarking are emerging both as information resources and as tools for research. This paper reflects on these technologies and suggests they may be well placed to build fluency in the higher-order thinking skills outlined in various information literacy frameworks, particularly in an educational context. A high proportion of today's learners are very comfortable with technology and Web 2.0 resources. The characteristics of the information they are accessing are also changing, bringing a stronger need for sophisticated evaluation and analysis skills. Where do social technologies fit within information literacy frameworks, and where can they be used in the day-to-day instruction of information skills? This paper suggests social technologies perform a dual role: they are not only useful sources of information but also resources to be used to develop ideas and research, using collaboration and community platforms that learners today are familiar with. Librarians who provide information literacy instruction would benefit from an awareness of these tools and where they sit within today's information environment. 相似文献

ABSTRACT The CMA Infobase is a free Web-based resource that contains evidence-based clinical practice guidelines. The database is maintained by the Canadian Medical Association (CMA) and is available on its Web site. The CMA Infobase currently contains 1,200-plus clinical practice guidelines either developed or endorsed by an authoritative health care organization located in Canada. It is an alternative source of free clinical practice guidelines to the National Guideline Clearinghouse. This column will cover the basics of CMA Infobase, including searching, special features, and available resources which complement the database. 相似文献

Constructing home pages for World-Wide Web access has become a major activity in academic health sciences libraries. At the Northwestern University, Galter Health Sciences Library staff are creating the library's new health information system using Web resources and integrating them with existing library systems-NUmed (OVID MEDLINE) and LUIS/NUcat (NOTIS). Development of Web pages, including selection and organization of electronic information, has become the building process for the electronic library. Selection, organization, design, and construction are important factors in the creation of an efficient and useful information system. Using resources like the World-Wide Web and tools like Netscape, library staff are designing an interface, defining policies and guidelines, and creating the tools that will give users easy access to local and international electronic, scholarly information resources. In this paper, the process used at Northwestern is shown as a model of an electronic health sciences library for the twenty-first century. 相似文献

Even though the library subscribes to numerous valuable health science resources, many e-books are not being used by clinicians, researchers, and students. Because these resources are bundled in various packages that often do not show up in federated searches, making them more discoverable is important. At the same time, the cost of textbooks is increasingly burdensome for students. Using authoritative lists and metrics to evaluate these resources while also seeking faculty input to include the best resources in subject guides may not only benefit the faculty and students but also aid in promoting library resources. 相似文献

ABSTRACT The new, social Web is fun and easy to use. The same cannot usually be said of library Web sites and digital resources. Libraries would benefit from incorporating aspects of the Read/Write Web into their services. This article examines how libraries currently erect barriers to service and provides an example of how these barriers could be eliminated by the creation of a social library research environment. 相似文献
