In this article it is presented a bibliometric analysis of e-government research in the Ibero-American (IA) Community. Data from the Scopus® database relating to 1129 research documents published between 2003 and 2017 was used. Presented analyzes include the most productive and impacting researchers, institutions and countries; determinants for country results; most relevant subject areas and specific research themes; and international cooperation patterns, namely within the IA Community. Contrary to what happens worldwide, e-government research production is still rising in IA. Besides the general heterogeneity, there are four relatively homogenous groups of countries to what concerns production and impact: leading, evolving, emerging, and expectant countries. IA has distinctive characteristics that make it interesting as an object of study and that constitute an opportunity for further development. Nevertheless, for results to continue to evolve, it is relevant that public policies related to e-government development and the promotion of research continue to be developed and that cooperation among IA researchers is properly promoted and supported.  相似文献

A decade of AIDS literature.   总被引:2,自引:0,他引:2  
From 1983 through mid-1991, more than 200,000 MEDLINE entries were AIDS-related. Close to 60% of the journals indexed in MEDLINE published at least one article on AIDS during the past ten years. As reflected by a subset of 29,077 MEDLINE records, the literature of AIDS has grown to encompass 29 languages and 65 countries. A bibliometric study of the medical literature helps to demonstrate the progression of AIDS as a world health problem and the concomitant expansion of the research effort underway to control it.  相似文献

The role nurses occupy in the care of the HIV/AIDS affected has evolved over time. This evolution is exhibited in the body of nursing knowledge and is recorded in the published literature. The purpose of this study was to describe landmarks in the evolution of nursing's involvement in the provision of care to HIV/AIDS patients and to examine the body of nursing knowledge relative to HIV/AIDS, employing bibliometric analytic techniques. It was expected that the literature would grow in both breadth and depth concurrent with nursing's increased role in caring for those infected, or at risk for infection, with HIV.  相似文献

This paper describes the potential for bibliometric analysis of citation data from the literature of the arts and humanities. To date, such analyses have been very limited, due to the subject orientation of most bibliometric researchers and to the lack heretofore of an appropriate citation data base. Opportunities are opening up for bibliometric research in the arts and humanities, and this research has particular application for journal collection management.  相似文献

Prior research has suggested that providing free and discounted access to the scientific literature to researchers in low‐income countries increases article production and citation. Using traditional bibliometric indicators for institutions in sub‐Saharan Africa, we analyze whether institutional access to TEEAL (a digital collection of journal articles in agriculture and allied subjects) increases: (i) article production; (ii) reference length; and (iii) number of citations to journals included in the TEEAL collection. Our analysis is based on nearly 20,000 articles – containing half a million references – published between 1988 and 2009 at 70 institutions in 11 African countries. We report that access to TEEAL does not appear to result in higher article production, although it does lead to longer reference lists (an additional 2.6 references per paper) and a greater frequency of citations to TEEAL journals (an additional 0.4 references per paper), compared to non‐subscribing institutions. We discuss how traditional bibliometric indicators may not provide a full picture of the effectiveness of free and discounted literature programs.  相似文献

There is a significant volume of scientific and technical documents, as opposed to report literature, available from federal and state government agencies. There is also a considerable number of government journals in the sciences containing research related information. Yet, there are not many studies available in library literature about the value of such materials to and their use by academic science and technology faculty in their teaching or research. The few surveys which have been conducted in the past point towards a lower minimal use of these documents. This, however, is not enough evidence to justify a generalization that scientific and technical documents fall under the low use category in academic libraries. Assuming that this is so, one needs to find out whether any programs like SDI by subject bibliographers can be instituted to augment user awareness. The article raises some pertinent questions relating to this topic, such as, how academic scientists become aware of the existence of these documents, what is their utility in academic teaching and research, how has the online and ondisc technology affected their use and finally, whether the publishing habits of academic scientists and technologists have any bearing on the library use patterns of these documents.  相似文献

A bibliometric analysis was applied in this work to evaluate global scientific production of geographic information system (GIS) papers from 1997 to 2006 in any journal of all the subject categories of the Science Citation Index compiled by Institute for Scientific Information (ISI), Philadelphia, USA. ‘GIS’ and ‘geographic information system’ were used as keywords to search parts of titles, abstracts, or keywords. The published output analysis showed that GIS research steadily increased over the past 10 years and the annual paper production in 2006 was about three times 1997s paper production. There are clear distinctions among author keywords used in publications from the five most productive countries (USA, UK, Canada, Germany and China) in GIS research. Bibliometric methods could quantitatively characterize the development of global scientific production in a specific research field. The analytical results eventually provide several key findings.  相似文献

Diet and nutrition are directly involved in patient care protocols that reflect a shift in the treatment of HIV/AIDS as a chronic disease, with an emphasis on quality of life and expanded life trajectory. Research concerning HIV/AIDS and nutrition is multidisciplinary, yielding study results that appear in a wide variety of scholarly journals. The purpose of this research was to employ bibliometric techniques to evaluate the body of literature specific to HIV/AIDS and nutrition as well as to determine content overlap among major bibliographic citation databases.  相似文献

Objective: To document and describe the University of Zambia Medical library’s responses to the fight against HIV/AIDS in Zambia. Methods: The methodology adopted was a case study approach combined with an analysis of the literature such as annual reports and official documents. This was augmented by personal reflections of the author having worked at the Medical Library. Results: The University of Zambia Medical library has over the years instituted and implemented HIV/AIDS information provision programmes that include the provision of information in various formats ‐‐ print or electronic and, in addition, capacity building in HIV/AIDS information literacy skills. Conclusion: A library’s social responsibility calls for it to be part of national responses to crises that arise in society. As HIV/AIDS has affected every aspect of Zambian society prevention, treatment, care and support there is an understanding that the library’s role should be using the cri tical and strategic resource at its disposal – information ‐‐ as part of their contribution to the fight against HIV/AIDS. In this context, libraries should source, collect, organize and disseminate information on HIV/AIDS in a way that is easily accessible to researchers, HIV/AIDS programme implementation agencies and the ordinary public.  相似文献

A ten year period of professional literature appearing in the Communication Yearbook, published by the International Communication Association from 1977 to 1986, was subjected to bibliometric analysis in an attempt to comprehend the nature of the scholarly endeavor. The content of the articles was analyzed and compared for frequency of mention of the types of research programs, theories, and methodologies undertaken in the field. Additional comparisons were drawn to similarities in the field of librarianship, especially reference/information work.  相似文献
