Abstract

Three major international library science journals -International Information and Library Review, Information Development and Libri are studied to determine the nature and trends in library and information science research in Africa. 72 papers are analysed, covering the period 1990-1992 (three years). This includes the status of the authors, gender, affiliation, country and types of research. The type and origin of cited documents the authors used in writing articles were also explored. The findings show that more information professionals in Africa are getting involved in research and publishing, with the major areas being agricultural information and library education. A majority of the journals cited, however, came from outside Africa.  相似文献

ABSTRACT

High-choice media environments allow people to cocoon themselves with like-minded messages (confirmation bias), which could shape both individual attitudes and perceived prevalence of opinions. This study builds on motivated cognition and spiral of silence theory to disentangle how browsing political messages (both selective exposure as viewing full articles and incidental exposure as encountering leads only) shapes perceived public opinion and subsequently attitudes. Participants (N?=?115) browsed online articles on controversial topics; related attitudes and public opinion perceptions were captured before and after. Multi-level modeling demonstrated a confirmation bias. Both selective and incidental exposure affected attitudes per message stance, with stronger impacts for selective exposure. Opinion climate perceptions mediated selective exposure impacts on attitudes.  相似文献

Abstract

This survey examines the basic needs of Harvard Law Faculty for information about new books and current journal articles. The purpose of this survey was to examine new media and technology in order to develop better current awareness tools, to better utilize the online catalog as a method of delivering current information to faculty, and to produce a new publication that fills in the gaps left by Current Index to Legal Periodicals and other sources. This survey looks at the production and circulation of photocopied pages of law reviews, recent acquisition lists, document delivery and interdisciplinary current awareness needs.  相似文献

ABSTRACT

This study examines the coverage of Eastern Europe and the Soviet Union and its successor states by U.S. journals indexed in Library Literature between 1990 and 2000. Seventy-one journals were evaluated according to subject content, geographical coverage, document type, and year of article publication. The study found that the majority of articles focused on domestic and foreign library activities. Coverage peaked between the years 1990 and 1994, with a steady decline after that. The study reports on differences in coverage by peer-reviewed and non-peer-reviewed journals over this decade.  相似文献

In this time of increasing pressure against incumbent licensees at renewal time, all aspects of the renewal process have come into sharper focus and importance. One topic of special interest has been the licensee's “Ascertainment of Community Needs”; section of his renewal form. Hoping to make the process more realistic, the FCC issued revised guidelines on the ascertainment process early in 1971. This issue of the Journal offers four articles exploring the present status of ascertainment, beginning with this overview of a sample of western television licensees which compares ascertainment filings in 1968 (before the FCC Primer) and 1971 (among the first filed afterwards) and demonstrates that the new FCC policy is having a telling effect. Dr. Joseph Foley is assistant professor of speech communications at Ohio State University.  相似文献

Abstract

Presently, eating disorders affect millions of people. Today, the media and the Internet are major publishing channels for consumer health information. Much research has found that the media may offer insufficient information on eating disorders. This research examines the quantity of adult consumer health publications on eating disorders in magazine articles and on the Internet in 1998 and investigates the effectiveness of Internet search engines. The results indicate that the resources found in popular magazines and on the Internet are not adequate, and that the Internet search engines are not effective in searching for information.  相似文献

Abstract

As the number of periodical titles in electronic editions increase, and as libraries are faced with new restrictions for sharing articles from site-licensed periodical literature, copyright issues surface. Understanding the characteristics of articles users now request can facilitate discussion. This paper presents the attributes of articles sought through OCLC Interlibrary Loan. Nearly two-thirds of the requested articles were published within five years. Over 80% of the periodical source titles were sought five or fewer times a year.  相似文献

ABSTRACT

Second-level agenda-setting suggests that news media influence how we think. As a case study examining the nature and effects of mainstream news media’s coverage of the 2015 Apple/FBI dispute about data privacy versus national security, this study found via content analysis that a majority of articles covering the dispute (73.7%) made the same potentially misleading claim about how the American public feels about the dispute. Nearly half (45.6%) of those articles made public opinion claims without offering empirical evidence, and almost all articles (97.4%) that cited the Pew survey appeared to have inadvertently created an unsubstantiated social reality. Then, this study found in a subsequent experiment that, consistent with impersonal influence, the above-mentioned news portrayals significantly affected the participants’ view on Americans’ collective opinion towards the Apple/FBI dispute. The long-term effect of this journalistic oversight is notable. Theoretical implications and practical recommendations for future science communication in the news are discussed.  相似文献

Abstract

The author contends, based on articles published in recent years discounting the legal obligation of law librarians to pro se patrons, that law librarians have a paramount ethical obligation not to cause harm, and thus to avoid the practice of law from the reference desk. As a result, the attorney patron and the pro se patron cannot be afforded the same level of legal reference service. The attorney is the conversant intermediary between the legal materials (and the librarian) and the client, whereas the pro se patron is the client with a layman's dearth of basic legal knowledge.  相似文献

PurposeThis paper aims to examine whether Altmetric data can be used as an indicator for identifying predatory journals.Design/methodology/approachThis is an applied study which uses citation and Altmetrics methods. The study selected 21 predatory journals from the Beall's list and Kscien's list, as well as 18 non-predatory open access journals from the DOAJ's list, in the field of Library and Information Science. The Altmetric score for articles published in these journals was obtained from the Altmetric Explorer, a service provided by Altmetric.com. Web of Science was used to search for citation data of articles published in these journals.FindingsThe predatory journals almost have no presence in social media, with poor Altmetric score. In contrast, non-predatory open access journals have a high presence rate and Altmetric score. There is a significant positive correlation between the number of articles cited and the number of articles having Altmetric score among non-predatory open-access journals, but not among predatory journals. Poor Altmetric score may be viewed as a potential characteristic of predatory journals, but other indicators would also need to be considered to determine whether a journal is predatory.Originality/valueDistinct from the traditional research methods, this study combined citation analysis and Altmetrics analysis. By comparing the characteristics of predatory journals and non-predatory open access journals, the findings contribute to the identification of predatory journals.  相似文献

Objective:Locating systematic reviews is essential for clinicians and researchers when creating or updating reviews and for decision-making in health care. This study aimed to develop a search filter for retrieving systematic reviews that improves upon the performance of the PubMed systematic review search filter.Methods:Search terms were identified from abstracts of reviews published in Cochrane Database of Systematic Reviews and the titles of articles indexed as systematic reviews in PubMed. Both the precision of the candidate terms and the number of systematic reviews retrieved from PubMed were evaluated after excluding the subset of articles retrieved by the PubMed systematic review filter. Terms that achieved a precision greater than 70% and relevant publication types indexed with MeSH terms were included in the filter search strategy.Results:The search strategy used in our filter added specific terms not included in PubMed''s systematic review filter and achieved a 61.3% increase in the number of retrieved articles that are potential systematic reviews. Moreover, it achieved an average precision that is likely greater than 80%.Conclusions:The developed search filter will enable users to identify more systematic reviews from PubMed than the PubMed systematic review filter with high precision.  相似文献

Objective:This study compares two maps of biomedical sciences using Medical Subject Headings (MeSH) term co-assignments versus MeSH terms of citing/cited articles and reveals similarities and differences between the two approaches.Methods:MeSH terms assigned to 397,475 journal articles published in 2015, as well as their 4,632,992 cited references, were retrieved from Web of Science and MEDLINE databases, respectively, which formed over 7 million MeSH co-assignments and nearly 18 million direct citation pairs. We generated six network visualizations of biomedical science at three levels using Gephi software based on these MeSH co-assignments and citation pairs.Results:The MeSH co-assignment map contained more nodes and edges, as MeSH co-assignments cover all medical topics discussed in articles. By contrast, the MeSH citation map contained fewer but larger nodes and wider edges, as citation links indicate connections to two similar medical topics.Conclusion:These two types of maps emphasize different aspects of biomedical sciences, with MeSH co-assignment maps focusing on the relationship between topics in different categories and MeSH direct citation maps providing insights into relationships between topics in the same or similar category.  相似文献
