"耗散结构"属非平衡态统计物理和不可逆过程热力学理论,一个非平衡系统不断从外界吸取能量,又不断向外界耗散能量,保持其相对的定态即耗散结构就必须不断地注入"负熵流". 相似文献

AbstractPublic libraries are a source of information and resources for the local community, they also play a role in the use of technologies such as geographic information systems (GIS) in that regard. GIS uses maps as output mediums for displaying demographic or similar information, as well as for spatial comparison or spatially based analysis. This is useful for gaining knowledge as well as for decision making. This article reports research into the awareness and use of GIS-type systems in public library settings in hopes of better understanding the benefits, drawbacks, and limitations to use of systems such as these. Primary findings suggest that there continues to exist limited understanding of the capabilities of GIS technology in public libraries and therefore very little demand for it exists in public librarians and patrons alike. 相似文献

AbstractThis paper advances a new interpretation of the development and current decline of public libraries in Egypt based on the study of international influences which helped to shape national discourses about development and provided the context for policy making and resource allocation in Egypt. After 1945 UNESCO encouraged fundamental education and the development of public libraries as operational tools of "education for development". Public libraries witnessed remarkable growth, but then, in the late 1960s, the dominant international discourse about development shifted under the influence of dependency theory to emphasize the need for developing countries to develop from within. Information for development became a self-evident requirement, but the new priority displaced public libraries in favor of specialized information systems for decision-makers. Traditionally, public library decline is attributed to local factors and issues of scarcity. In the case of Egypt, however, factors of scarcity are better interpreted as symptoms than as underlying causes of decline. This paper maintains that the current state of decline of public libraries in Egypt is primarily a consequence of public policy choices precipitated by a shift in international as well as national development priorities, not of factors inherent in the country’s political, social and cultural fabric. 相似文献

In October 1998, the National Library of Medicine (NLM) launched a pilot project to learn about the role of public libraries in providing health information to the public and to generate information that would assist NLM and the National Network of Libraries of Medicine (NN/LM) in learning how best to work with public libraries in the future. Three regional medical libraries (RMLs), eight resource libraries, and forty-one public libraries or library systems from nine states and the District of Columbia were selected for participation. The pilot project included an evaluation component that was carried out in parallel with project implementation. The evaluation ran through September 1999. The results of the evaluation indicated that participating public librarians were enthusiastic about the training and information materials provided as part of the project and that many public libraries used the materials and conducted their own outreach to local communities and groups. Most libraries applied the modest funds to purchase additional Internet-accessible computers and/or upgrade their health-reference materials. However, few of the participating public libraries had health information centers (although health information was perceived as a top-ten or top-five topic of interest to patrons). Also, the project generated only minimal usage of NLM's consumer health database, known as MEDLINEplus, from the premises of the monitored libraries (patron usage from home or office locations was not tracked). The evaluation results suggested a balanced follow-up by NLM and the NN/LM, with a few carefully selected national activities, complemented by a package of targeted activities that, as of January 2000, are being planned, developed, or implemented. The results also highlighted the importance of building an evaluation component into projects like this one from the outset, to assure that objectives were met and that evaluative information was available on a timely basis, as was the case here. 相似文献

指出公共图书馆进行基于"城市记忆"的地方文献建设不但具有必要性,而且与其他机构相比具有绝对的优势。认为在建设策略方面,应从文献收集、文献整理、文献利用等方面入手,开创地方文献建设的新局面,让公共图书馆真正成为"城市记忆"的记录者和保护者。 相似文献
