The study undertakes a systematic literature review of government-provided E-Services for businesses (Government to Business E-Services). The literature review process selects and analyses 331 publications. The research highlights the polydispersity of identified publications, resulting from the fragmentation of disciplines. The primary activities in this research field occur mainly in Europe and Asia. In addition, there is a steady engagement of researchers on G2B E-Services. The overall maturity level of governmental services identified in the literature review is quite satisfactory. The main research topics are E-Procurement, E-Customs, E-Taxes, Interoperability, Process Transformation, Cost and Pricing Issues, Barriers and Key Success Factors, and Assessment of Effectiveness. Case studies and surveys are the most popular research methods. In the future, a deeper analysis of the stakeholders' views, enhancement of planning, development and transformation of G2B E-Services, redesign of back-office processes, and interoperability between different systems should attract research interest. Finally, we expect further analysis of E-Customs and E-Invoices, as these services have significant added value. 相似文献

In this paper we present a number of metrics for usage of the SAO/NASA Astrophysics Data System (ADS). Since the ADS is used by the entire astronomical community, these are indicative of how the astronomical literature is used. We will show how the use of the ADS has changed both quantitatively and qualitatively. We will also show that different types of users access the system in different ways. Finally, we show how use of the ADS has evolved over the years in various regions of the world. 相似文献

Objectives:
The study updates Schloman''s 1997 study, “Mapping the Literature of Health Education.” The authors identify an updated list of core health education journals and determine the coverage of these journals by electronic indexes.Methods:
Citations from four source journals for the years 2006 to 2008 were analyzed using the established methodology of the “Mapping the Literature of Allied Health Project.” The cited journals were divided into three zones of productivity by using Bradford''s Law of Scattering.Results:
There were 19,907 citations in 602 source articles. Journal articles were the most commonly cited format type. Of the 1,896 journal titles cited, 20 (1.1%) made up the core journals. Together, the fields of medicine, health education, and psychology accounted for 85.0% of the journals in the core. Self-citation was found to be a common practice in the source journals. Scopus had the broadest journal coverage of the indexes examined.Conclusions:
The results of this study provide a new picture of the health education literature: The volume has grown significantly, cites older materials, and relies less on sexual health journals and more on psychology journals.Highlights
- Three of the four health education journals in this study showed a statistically significant increase in the number of journal articles published since 1993.
- The majority of core journals in the field are from medicine (35.0%), health education (30.0%), and psychology (20.0%), with the largest change in core journal make-up being an increase in psychology journals.
- Scopus provided the most thorough coverage of the cited journals, followed by MEDLINE, Social Sciences Citation Index, and CINAHL Plus with Full Text.
Implications
- Reference librarians should instruct users on more sophisticated ways to manage the growing volume of the health education literature.
- Collection development librarians may need to purchase and retain older materials to support health education research.
- Librarians should purchase and direct patrons to a variety of databases to completely cover the literature of medicine, health education, and psychology.

Recent studies have concluded that American contributions to science literature have been in relative decline, whereas contributions from other parts of the world such as the European Union and Asia have increased. Is the same true for the areas of bibliometrics, informetrics and scientometrics? This study investigates the growth and geographic distribution of metrics research for the period 1987–2008. Similar to studies of other disciplines or science in general, the findings reveal that the United States continues to dominate, but there has been a recent relative decline in North American contributions overall. European and Asian contributions have grown substantially. National and institutional collaborations that contribute to this growth do not necessarily follow close geographic proximity, although European nations have been more active with international collaborations overall, both within Europe and elsewhere. 相似文献

Objectives:
The research identified the publication types and ages most frequently cited in the infectious diseases literature and the most commonly cited journals.Methods:
From 2008–2010, 5,056 articles in 5 infectious diseases journals cited 166,650 items. Two random samples were drawn: one (n = 1,060) from the total set of citations and one (n = 1,060) from the citations to journal articles. For each sample citation, publication type and date, age of cited item, and inclusion of uniform resource locator (URL) were collected. For each item in the cited journal articles sample, journal title, publication date, and age of the cited article were collected. Bradford zones were used for further analysis.Results:
Journal articles (91%, n = 963) made up the bulk of cited items, followed by miscellaneous items (4.6%, n = 49). Dates of publication for cited items ranged from 1933–2010 (mean = 2001, mode = 2007). Over half (50.2%, n = 483) of cited journal articles were published within the previous 5 years. The journal article citations included 358 unique journal titles.Discussion:
The citations to current and older publications in a range of disciplines, heavy citation of journals, and citation of miscellaneous and government documents revealed the depth and breadth of resources needed for the study of infectious diseases.Highlights
- Literature on infectious diseases is multidisciplinary, encompassing medical specialties, public health, and the medical sciences.
- Infectious disease publications cite journal articles more than 90% of the time. Cited journal articles greatly range in age at citation: more than a quarter were over 10 years old.
- Infectious disease citation patterns resemble clinical medicine citation patterns more than public health citation patterns.
Implications
- Infectious disease professionals need access to general medicine titles as well as infectious disease, immunology, virology, microbiology, and public health literature.
- Librarians serving infectious disease researchers and practitioners should provide access to older materials, especially journal back files, to support the cyclical needs of their patrons.

This study investigates how Chinese students make credibility assessments of web-based information for their research, and what evaluation criteria they employ. Our findings indicate that presumed credibility, reputed credibility, and surface credibility have a stronger impact on undergraduate students than on graduate students in credibility assessment. Graduate students tend to value experienced credibility more than undergraduate students. Undergraduate students predominantly rely on author's name/reputation/affiliation as well as website reputation for their credibility evaluation. In contrast, graduate students focus more than undergraduate students on information accuracy/quality. Similarities and differences in credibility assessment between American students and Chinese students are also discussed. 相似文献

AbstractIn Great Britain and the United States common developmental issues have resulted in the evolution of two very different models of school library provision. In the United States, school libraries are integrated media centers, separate from public library influence, staffed by specialists with dual training in teaching and librarianship, and dedicated to an educational mission. British school libraries are contested terrain with two patterns of staffing, support by Public Library Services, and incomplete formulation of mission and rationale. This article discusses five factors which have facilitated or retarded school library development in the two countries (standards, staffing and certification, government support, rationale, professionalization) and generalizes about development factors and the successful promotion of school libraries. 相似文献

With the increasing dominance of digital reading over traditional reading, gaining an understanding of the environmental impacts of the formats has become critical. This systematic literature review synthesizes and integrates the findings of studies comparing print reading with on-screen reading. The results reveal that the environmental impacts of printed and digital media depend on the usage rates and number of readers of both types of media as well as user behaviors and other parameters, and digital reading also has its own negative environmental impacts. Finally, research gaps are identified and a research agenda is proposed, including considering environmental performance in comparison studies, empirical investigations of actual user behaviors, and environmental savings for lending and sharing materials from libraries. This study aims to clear the misconception and change the popular stereotype that “e-reading is environmentally more sustainable than conventional reading,” and to provide stakeholders with more valuable information that is necessary to make environmentally informed decisions. 相似文献

Peer review is a cornerstone of scientific publication, and consequently, predatory journals are feared to be a threat to the credibility of science as they perform no or low‐quality peer review. The question of why researchers decide to publish in a questionable journal remains relatively unexplored. This paper provides an overview of the existing literature on why researchers decide to publish papers in questionable journals, specifically whether or not they search for a low‐barrier way to getting published while being aware that the chosen journal probably does not adhere to acceptable academic standards. The choice of a publication outlet can be seen as a submission tree that consists of various incentives, and explaining why authors publish in deceptive journals may thus consist of a combination of awareness and motivational factors. Awareness and motivation of diligent authors is very different from that of unethical authors. Unethical authors may use a lack of awareness to excuse their actions, but they may actively search for a low‐barrier way to getting published. As there are different types of authors who publish in deceptive journals, we need different approaches to solve the problem. 相似文献

OBJECTIVES: Medicine must keep current with the research literature, and keeping current requires continuously updating the clinical knowledge base (i.e., references that provide answers to clinical questions). The authors estimated the volume of medical literature potentially relevant to primary care published in a month and the time required for physicians trained in medical epidemiology to evaluate it for updating a clinical knowledge base. METHODS: We included journals listed in five primary care journal review services (ACP Journal Club, DynaMed, Evidence-Based Practice, Journal Watch, and QuickScan Reviews). Finding little overlap, we added the 2001 "Brandon/Hill Selected List of Print Books and Journals for the Small Medical Library." We counted articles (including letters, editorials, and other commentaries) published in March 2002, using bibliographic software where possible and hand counting when necessary. For journals not published in March 2002, we reviewed the nearest issue. Five primary care physicians independently evaluated fifty randomly selected articles and timed the process. RESULTS: The combined list contained 341 currently active journals with 8,265 articles. Adjusting for publication frequency, we estimate 7,287 articles are published monthly in this set of journals. Physicians trained in epidemiology would take an estimated 627.5 hours per month to evaluate these articles. CONCLUSIONS: To provide practicing clinicians with the best current evidence, more comprehensive and systematic literature surveillance efforts are needed. 相似文献
