This paper explores a project funded through the National Network of Libraries of Medicine to enhance effective use of the Internet by public health professionals. The processes and outcome of an effort to develop a statewide Web site for public health professionals are described. A series of focus groups was conducted as a preliminary data-gathering tool to evaluate the information needs of the target population. Results of the focus group provided a valuable framework upon which to build a successful schema for Web site development.  相似文献

This paper discusses concepts and terminology of some aspects of the autoimmune and rheumatic disorders as related to medical reference work. Details of anatomic, biochemical, and pathologic processes are not discussed. Knowledge of the specific terminology involved in this area may help to ensure a good approach to developing prudent strategies for database searching of the medical literature and, therefore, is reviewed. MeSH thesaurus terms are shown and textword synonyms are presented that provide tools for thorough searching techniques. Commonly used medical jargon as well as older terminology for this area is also explained. Examples of specific search strategies are illustrated.  相似文献

This article is an edited and condensed version of the report of a study carried out under the auspices of the Joint Information Systems Committee (JISC) and the Publishers Association (PA). It develops the conclusions of an earlier analysis (Bide, Oppenheim & Ramsden, 1997) and builds upon discussions between representatives of JISC and the PA held in the summer of 1997. The full report is available on the UKOLN server at www.ukoln.ac.uk/services/elib/papers/pa/charging/  相似文献

Despite the ubiquity and critical importance of science and technology in international affairs, their role receives insufficient attention in traditional international relations curricula. There is little literature on how the relations between science, technology, economics, politics, law and culture should be taught in an international context. Since it is impossible even for scientists to master all the branches of natural science and engineering that affect public policy, the learning goals of students whose primary training is in the social sciences should be to get some grounding in the natural sciences or engineering, to master basic policy skills, to understand the basic concepts that link science and technology to their broader context, and to gain a respect for the scientific and technological dimensions of the broader issues they are addressing. They also need to cultivate a fearless determination to master what they need to know in order to address policy issues, an open-minded but skeptical attitude towards the views of dueling experts, regardless of whether they agree with their politics, and (for American students) a world-view that goes beyond a strictly U.S. perspective on international events. The Georgetown University program in Science, Technology and International Affairs (STIA) is a unique, multi-disciplinary undergraduate liberal arts program that embodies this approach and could be an example that other institutions of higher learning might adapt to their own requirements.  相似文献

Literacy education in Nigerian history finds its roots in the efforts of missionary endeavour. Subsequent work in the field has always been piecemeal and unco-ordinated, even though a degree of success has been achieved and valuable experience gained. The Federal Government's decision to launch a Mass Literacy Campaign in 1982 is primarily a political response to the needs and exigencies of a developing country rich both in natural and manpower resources. The campaign is seen not only as a necessary means of creating a permanently literate society within ten years but also as an assertion of the nation's unity. The problems of undertaking such a project are immensely complicated by the plethora of local languages and cultures, the preservation of which is seen to be imperative. But the campaign can succeed if the crucial issues identified in the article — functionality, personnel, training and materials, motivation, and above all the language to be used as the medium of literacy education — are resolved; if assistance from national development organisations and international bodies is matched by the determination of the government to create an environment capable of sustaining and reinforcing literacy and conducive to the use of the skills acquired; and if the illiterate respond with initiative and perseverence to the opportunity offered them.
Zusammenfassung Die Alphabetisierung in Nigeria hat ihre historischen Wurzeln in missionarischen Bemühungen. Alle spätere Arbeit auf diesem Gebiet war stückenhaft und unkoordiniert, wenn ihr auch ein gewisses Maß von Erfolg beschieden war und wertvolle Erfahrungen gemacht wurden. Der Beschluß der nigerianischen Regierung, im Jahre 1982 eine Massen-Alphabetisierungskampagne durchzuführen, ist vor allem eine politische Antwort auf die Bedürfnisse und Erfordernisse eines an natürlichen und menschlichen Ressource reichen Entwicklungslandes. Die Kampagne wird nicht nur als notwendiges Mittel angesehen, innerhalb von zehn Jahren eine bleibend alphabetisierte Gesellschaft zu schaffen, sondern auch als eine Bestätigung der Einheit der Nation. Die einem solchen Projekt anhaftenden Probleme werden durch die Vielfalt einheimischer Sprachen und Kulturen, deren Erhaltung als unerläßlich betrachtet wird, außerordentlich kompliziert. Dennoch kann das Unternehmen zum Erfolg führen, wenn die wichtigsten, in diesem Artikel herausgearbeiteten Fragen — Funktionalität, Personal, Ausbildung und Materialien, Motivation und besonders die für die Alphabetisierung benutzte Sprache — gelöst werden; wenn der Unterstützung durch nationale Entwicklungsstellen und internationale Organisationen eine entsprechende Entschlossenheit der Regierung gegenübersteht, eine Umgebung herzustellen, die die Alphabetisierung aufrechterhalten und konsolidieren kann und zum Gebrauch der erworbenen Fähigkeiten herausfordert; und wenn die Analphabeten die ihnen gebotene Gelegenheit mit Initiative und Ausdauer nutzen.

Résumé L'alphabétisation dans l'histoire nigériane prend sa source dans les efforts des missions religieuses. Le travail postérieur dans ce domaine a toujours été fragmentaire et sans coordination, bien qu'on ait atteint un certain degré de succès et qu'on ait acquis une expérience précieuse. La décision du Gouvernement Fédéral de lancer une Campagne d'Alphabétisation Massive en 1982 est avant tout une réponse politique aux besoins et aux exigences d'un pays en développement riche en ressources tant naturelles qu'humaines. Cette campagne est considérée non seulement comme un moyen nécessaire de créer une société définitivement alphabète en dix ans mais aussi comme une assertion de l'unité de la nation. Les problèmes soulevés par l'entreprise d'un tel projet sont énormément compliqués par la pléthore des langues et des cultures indigènes, dont la préservation est regardée comme impérative. Néanmoins, cette campagne a des chances de réussir si les points critiques identifiés dans cet article — fonctionnalité, personnel, formation et matériel, motivation, et par dessus tout la langue à employer comme véhicule de l'alphabétisation — sont résolus; si l'assistance accordée par les organisations pour le développement national et par les organismes internationaux rencontre sur le même niveau la détermination du gouvernment de créer un environment capable de maintenir et de renforcer l'alphabétisation qui soit aussi favorable à l'utilisation des connaissances et de l'expérience acquises; et si les illettrés répondent par la persévérance et par l'initiative aux occasions qui leur sont offertes.

Atmospheric carbon dioxide concentration [CO2], incoming solar radiation and sea ice coverage are among the most important factors that control the global climate. By applying the simple cell-to-cell mapping technique to a simplified atmosphere-ocean-sea ice feedback climate model, effects of these factors on the stability of the climatic system are studied. The current climatic system is found to be stable but highly nonlinear. The resiliency of stability increases with [CO2] to a summit when [CO2] reaches 290 μL/L which is comparable to the pre-industrial level, suggesting carbon dioxide is essential to the stability of the global climate. With [CO2] rising further, the global climate stability decreases, the mean ocean temperature goes up and the sea ice coverage shrinks in the polar region. When the incoming solar radiation is intensified, the ice coverage gradually diminishes, but the mean ocean temperature remains relatively constant. Overall, our analysis suggests that at the current levels of three external factors the stability of global climate is highly resilient. However, there exists a possibility of extreme states of climate, such as a snow-ball earth and an ice-free earth.  相似文献

Handedness has been studied for association with language-related disorders because of its link with language hemispheric dominance. No clear pattern has emerged, possibly because of small samples, publication bias, and heterogeneous criteria across studies. Non-right-handedness (NRH) frequency was assessed in N = 2503 cases with reading and/or language impairment and N = 4316 sex-matched controls identified from 10 distinct cohorts (age range 6–19 years old; European ethnicity) using a priori set criteria. A meta-analysis (Ncases = 1994) showed elevated NRH % in individuals with language/reading impairment compared with controls (OR = 1.21, CI = 1.06–1.39, p = .01). The association between reading/language impairments and NRH could result from shared pathways underlying brain lateralization, handedness, and cognitive functions.  相似文献
