The problem of how to rank academic journals in the communication field (human interaction, mass communication, speech, and rhetoric) is one of practical importance to scholars, university administrators, and librarians, yet there is no methodology that covers the field's journals comprehensively and objectively. This article reports a new ranking methodology based in empirical criteria. The new system relates independent measures of the prestige of the field's doctoral departments to information about where faculty members from those departments have published scholarly articles. This new approach identifies the field's most influential journals as those that more frequently publish the work of the field's top scholars and programs as perceived by their peers. This system was used to compute prestige weights (P-weights) for 65 communication journals. P-weights were found to be strongly correlated with ISI Web of Science journal impact factor scores and can be used to identify an overall prestige hierarchy for communication journals as well as prestige rankings by subject specialty. 相似文献

Objectives
This study describes the literature of hospital pharmacy and identifies the journals most commonly cited by authors in the field, the publication types most frequently cited, the age of citations, and the indexing access to core journals. The study also looks at differing citation practices between journals with a wide audience compared to a national journal with a focus on regional issues and trends in the field.Method
Cited references from five discipline-specific source journals were collected and analyzed for publication type and age. Two sets were created for comparison. Bradford''s Law of Scattering was applied to both sets to determine the most frequently cited journals.Results
Three-quarters of all cited items were published within the last 10 years (71%), and journal articles were the most heavily cited publication type (n=65,760, 87%). Citation analysis revealed 26 journal titles in Zone 1, 177 journal titles in Zone 2, and the remaining were scattered across 3,886 titles. Analysis of a national journal revealed Zone 1 comprised 9 titles. Comparison of the 2 sets revealed that Zone 1 titles overlapped, with the exception of 2 titles that were geographically focused in the national title.Conclusion
Hospital pharmacy literature draws heavily from its own discipline-specific sources but equally from core general and specialty medical journals. Indexing of cited journals is complete in PubMed and EMBASE but lacking in International Pharmaceutical Abstracts. Gray literature is a significant information source in the field. 相似文献3.
Specialist publications are an important part of professional and disciplinary development. They serve to communicate research; enable the development of a shared, contestable, and expanding knowledge base; support the educational programmes that advance the profession; grow practice; and inform the evolution of the discipline. In conservation, professional and peer-reviewed journals and other forms of publications support cultural, organisational, and scientific development; facilitate new and improved forms of conservation professional practice; enable the growth of a distinctive research-led discipline; and help conservation to more effectively compete with other disciplines for influence and funding. This paper reports on the findings of a study that investigated conservators’ opinions and experiences of peer-reviewed publishing. This study examined the value conservators place on the dissemination of their research; the obstacles to, and incentives in publishing; the views held by conservators of the benefits of publication to themselves and the field; and the impact of the field's inherent interdisciplinarity on the pattern of conservation publishing. Eighty-six conservators (conservators and conservation scientists) and ten journal editors completed an online questionnaire focusing on the communication of knowledge within the field of cultural materials conservation. Findings suggest that while the peer review process is valued, a significant number who responded indicated a preference for forms of communication other than in peer review journals or publishing in general. 相似文献

This paper explores a new indicator of journal citation impact, denoted as source normalized impact per paper (SNIP). It measures a journal's contextual citation impact, taking into account characteristics of its properly defined subject field, especially the frequency at which authors cite other papers in their reference lists, the rapidity of maturing of citation impact, and the extent to which a database used for the assessment covers the field's literature. It further develops Eugene Garfield's notions of a field's ‘citation potential’ defined as the average length of references lists in a field and determining the probability of being cited, and the need in fair performance assessments to correct for differences between subject fields. A journal's subject field is defined as the set of papers citing that journal. SNIP is defined as the ratio of the journal's citation count per paper and the citation potential in its subject field. It aims to allow direct comparison of sources in different subject fields. Citation potential is shown to vary not only between journal subject categories – groupings of journals sharing a research field – or disciplines (e.g., journals in mathematics, engineering and social sciences tend to have lower values than titles in life sciences), but also between journals within the same subject category. For instance, basic journals tend to show higher citation potentials than applied or clinical journals, and journals covering emerging topics higher than periodicals in classical subjects or more general journals. SNIP corrects for such differences. Its strengths and limitations are critically discussed, and suggestions are made for further research. All empirical results are derived from Elsevier's Scopus. 相似文献

Editor's Note: Given the rare use of autoethnography in the field of communication, I invited Dr. Tillmann to discuss autoethnography as a valuable tool in applied communication research. This discussion serves as a prelude to her essay “Body and Bulimia Revisited: Reflections on ‘A Secret Life.’” In 2004, two articles in the Journal of Applied Communication Research (Ashcraft & Tretheway, 2004; Goodall, 2004) celebrated the merits of auto- and narrative ethnography, methods of research grounded in lived experience and evocative modes of representation that seek to engage readers emotionally, aesthetically, ethically, and politically. Despite these and other persuasive calls for auto- and narrative ethnographic works, few have been published in communication journals. More than four years ago, JACR offered readers arguments for this kind of scholarship, yet no full-length autoethnography appeared in its pages—until now. This essay, a prelude to its companion, “Body and Bulimia Revisited,” speaks into that silence. 相似文献

Determining the core journals in a discipline serves an important role for both academic librarians and departmental faculty. In addition to helping librarians build or weed journal collections, especially in difficult budget years, core lists help departments seeking accreditation, committees evaluating a candidate’s scholarship for tenure and promotion, and faculty choosing publications for their research. They also assist faculty guiding student research in the discipline. However, because of the inexorable changes that have occurred, and will continue to occur, in scholarly communication, no such list can be considered immutable. The purpose of this study is to identify a method by which individual librarians and/or libraries can create a list of journals considered important to a discipline, one that accurately reflects the state of scholarly communication in a field as it relates to the currency and quality of journal literature, and that is sustainable over time. More specifically, our purpose is twofold. First, to develop a sustainable method for defining the universe of potential core titles; and, second, to identify the core titles within that universe. As the result of discussions on this issue with a social work faculty member, the authors used social work journals for developing a methodology that may be applied to other disciplines. 相似文献

Research effectiveness of periodicals indexed in the Readers' Guide to Periodical Literature was analyzed and related to obsolescence rates of scientif/research-oriented journals. Citations from 25 years of theses and dissertations found that most Readers' Guide titles were not used for research purposes. The bulk of citations occurred within 5 years of an article's publication and clustered in the same small number of titles. Implications for retention of titles indexed in the Readers' Guide are discussed. Use per unit o f shelf space, cost of storage, plus the minimal research ualue of Readers' Guide items make them a prime target for cooperative storage efforts. 相似文献

The study explores the publication trends of scholarly journal articles in two core Library and Information Science (LIS) journals indexed under ScienceDirect Database during the period for the period 2000–2010, and for the “Top 25 Hottest Papers” for 2006–2010. It examines and presents an analysis of 1000 research papers in the area of LIS published in two journals: The International Information & Library Review (IILR) and Library & Information Science Research (LISR). The study examines the content of the journals, including growth of the literature, authorship patterns, geographical distributions of authors, distribution of papers by journal, citation pattern, ranking pattern, length of articles, and most cited authors. Collaboration was calculated using Subramanyam's formula, and Lotka's law was used to identify authors' productivity. The results indicated that authors' distributions did not follow Lotka's law. The study identified the eight most productive authors with a high of 19 publications in this field. The findings indicate that these publications experienced rapid and exponential growth in literature production. The contributions by scientists from India are examined. 相似文献

This paper contributes to the longitudinal study and representation of the diffusion of scholarly knowledge through bibliometrics. The case of systems biology is used to illustrate a means for considering the structure and different roles of journals in the diffusion of a relatively new field to diverse subject areas. Using a bipartite network analysis of journals and subject categories, a core–intermediary–periphery diffusion structure is detected through comparative analysis of betweenness centrality over time. Systems biology diffuses from a core of foundational, theoretical areas to more specific, applied, practical fields, most of which relate to human health. Next, cluster analysis is applied to subject category co-occurrence networks to longitudinally trace the movement of fields within the core–intermediary–periphery structure. The results of these analyses reveal patterns of systems biology's diffusion across both theoretical and applied fields, and are also used to suggest how the dynamics of a field's interdisciplinary evolution can be realized. The author concludes by presenting a typology for considering how journals may function to support attributes of the core–intermediary–periphery structure and diffusion patterns more broadly. 相似文献

This study replicates and extends Yates and Chapman's [(2007), Behavioral & Social Sciences Librarian, 26(1), 39–51] study of references from Communication Monographs, Communication Research, and Journal of Communication for the years 2010 and 2015 to draw further conclusions on the use of monographs in journal literature in the field of communication. Results show that the use of monographs in these journals has been outpaced by references to journal articles by a ratio of 5 to 1. The references were further analyzed by date and publisher. The authors then selected a random sample of the monographs cited in the journals to explore the availability of these monographs in electronic format and found that many are available as ebooks, particularly the more recent titles. The authors also examined the references from a collection of scholarly books in communication from 2005, 2010, and 2015 and found that the use of monographs may be declining slightly. The most notable trend in these references was the increase in the number of references to items in other formats such as film, television, comic books, and websites. The authors conclude that the monographs crisis is indeed affecting citation patterns in the field of communication. 相似文献

Objectives:
The purpose of this study was to identify (1) core journals in the literature of physical therapy, (2) currency of references cited in that literature, and (3) online databases providing the highest coverage rate of core journals.Method:
Data for each cited reference in each article of four source journals for three years were recorded, including type of literature, year of publication, and journal title. The journal titles were ranked in descending order according to the frequency of citations and divided into three zones using Bradford''s Law of Scattering. Four databases were analyzed for coverage rates of articles published in the Zone 1 and Zone 2 journals in 2007.Results:
Journal articles were the most frequently cited type of literature, with sixteen journals supplying one-third of the cited journal references. Physical Therapy was the most commonly cited title. There were more cited articles published from 2000 to 2007 than in any previous full decade. Of the databases analyzed, CINAHL provided the highest coverage rate for Zone 1 2007 publications.Conclusions:
Results were similar to a previous study, except for changes in the order of Zone 1 journals. Results can help physical therapists and librarians determine important journals in this discipline.Highlights
- More cited references were published in the last eight years studied than in any previous full decade.
- Physical Therapy, Archives of Physical Medicine and Rehabilitation (APMR), and Spine were the most frequently cited titles. Previous studies found APMR to be the most cited journal.
- CINAHL provided the highest coverage rate for the most commonly cited titles, with MEDLINE and EMBASE providing the best coverage for the next group of titles.
Implications
- Health sciences librarians and clinicians can use these results to identify important journals for developing collections and determining the need for access to back issues of journals.
- Multiple databases are needed for comprehensive coverage of the physical therapy discipline

Objective:This study aims to identify the core journals cited in the health care management literature and to determine their coverage in the foremost bibliographic databases used by the discipline.Methods:Using the methodology outlined by the Medical Library Association''s Nursing and Allied Health Resource Section (NAHRS) protocol for “Mapping the Literature of Nursing and Allied Health Professions,” this study updates an earlier study published in 2007. Cited references from articles published in a three-year range (2016–2018) were collected from five health care management journals. Using Bradford''s Law of Scattering, cited journal titles were tabulated and ranked according to the number of times cited. Eleven databases were used to determine coverage of the most highly cited journal titles for all source journals, as well as for a subset of practitioner-oriented journals.Results:The most highly cited sources were journals, followed by government documents, Internet resources, books, and miscellaneous resources. The databases with the most complete coverage of Zone 1 and 2 were Scopus, Web of Science Core Collection, and PubMed, while the worst performing databases were Health Business Elite, ABI/Inform, and Business Source Complete.Conclusions:The literature of health care management has expanded rapidly in the last decade, with cumulative citations increasing by 76.6% and the number of cited journal titles increasing by nearly 70% since the original study. Coverage of the core journals in popular databases remains high, although specialized health care management and business databases did not perform as well as general or biomedical databases. 相似文献

We propose a cross-field evaluation method for the publications of research institutes. With this approach, we first determine a set of the most visible publications (MVPs) for each field from the publications of all assessed institutes according to the field's h-index. Then, we measure an institute's production in each field by its percentage share (i.e., contribution) to the field's MVPs. Finally, we obtain an institute's cross-field production measure as the average of its contributions to all fields. The proposed approach is proven empirically to be reasonable, intuitive to understand, and uniformly applicable to various sets of institutes and fields of different publication and citation patterns. The field and cross-field production measures obtained by the proposed approach not only allow linear ranking of institutes, but also reveal the degree of their production difference. 相似文献

The major purpose of this study was to identify and assess indexing coverage of core journals in cytotechnology. It was part of a larger project sponsored by the Nursing and Allied Health Resources Section of the Medical Library Association to map the literature of allied health. Three representative journals in cytotechnology were selected and subjected to citation analysis to determine what journals, other publication types, and years were cited and how often. Bradford's Law of Scattering was applied to the resulting list of cited journals to identify core titles in the discipline, and five indexes were searched to assess coverage of these core titles. Results indicated that the cytotechnology journal literature had a small core but wide dispersion: one third of the 21,021 journal citations appeared in only 3 titles; another third appeared in an additional 26 titles; the remaining third were scattered in 1,069 different titles. Science Citation Index Expanded rated highest in indexing coverage of the core titles, followed by MEDLINE, EMBASE/Excerpta Medica, HealthSTAR, and Cumulative Index to Nursing and Allied Health Literature (CINAHL). The study's results also showed that journals were the predominantly cited format and that citing authors relied strongly on more recent literature. 相似文献

This article analyzes the bibliometric features (the number of pages, completion years, the fields of subject, the number of citations, and their distribution by types of sources and years) of 100 theses and dissertations completed at the Department of Librarianship of Hacettepe University between 1974 and 2002. Almost a quarter (24%) of all dissertations were on university libraries, followed by public libraries (9%). Doctoral dissertations were, on average, twice as long as master's theses and contained 2.5 times more citations. Monographs received more citations (50%) than journal articles did (42%). Recently completed theses and dissertations contained more citations to electronic publications. Fourteen (or 3.2% of all) journal titles (including Türk Kütüphaneciliği, College & Research Libraries, and Journal of the American Society for Information Science) received almost half (48.9%) of all citations. Eighty percent of journal titles were cited infrequently. No correlation was found between the frequency of citations of the most frequently cited journals and their impact factors. Cited journal titles in master's and doctoral theses and dissertations overlapped significantly. Similarly, journal titles cited in dissertations also overlapped significantly with those that were cited in the journal articles published in the professional literature. The distribution of citations to foreign journal titles fit Bradford's Law of Scattering. The mean half-life of all cited sources was 9 years. Sources cited in master's dissertations were relatively more current. Single authorship was the norm in cited resources. Coupled with in-library use data, findings of the present study can be used to identify the core journal titles in librarianship as well as to evaluate the existing library collections to decide which journal titles to keep, discard, or relegate to off-site storage areas. 相似文献

Citation analysis provides valuable information on researchers' information use behavior, and helps librarians make evidence-based collection development decisions. However, no citation analysis of faculty publications in the field of communication has been performed to study communication researchers' information use behavior. This study examined communication faculty publication from 2006 to 2014, analyzing format, age, most frequently cited journals, and their subject areas. Analysis of local holdings provides evidence for the library's role in support of faculty research, and helps librarians articulate the value of libraries. 相似文献

The purpose of this study was to identify core journals and the databases that provide access to these journals for the field of dental assisting. This study was completed as a part of the Medical Library Association (MLA) Nursing and Allied Health Resources Section's project to map the literature of allied health. There were three original journals selected for analysis using the prescribed methodology, Dental Assistant, the journal of the American Dental Assistants Association; Journal of the CDAA, the journal of the Canadian Dental Assistants' Association; and Dental Teamwork, published by the American Dental Association. Dental Teamwork ceased publication in December 1996; however, it was considered a necessary part of the analysis due to its extensive coverage of dental assisting as well as its numerous scientific articles with references. In Dental Assistant, there were 16 source articles, containing 206 citations. In Dental Teamwork, there were 31 source articles with 308 citations. In Journal of the CDAA, there were only 3 source articles with 14 citations. Bradford's Law of Scattering was applied to the journal citations. Four databases, MEDLINE, the Cumulative Index to Nursing and Allied Health Literature, EMBASE/Excerpta Medica, and HEALTH were analyzed for their coverage of these cited journals. This study may encourage the dental assisting profession to take a close look at its existing journals and to consider enhancing the content of these journals or the publication of additional journals in the field. Dental assistants of today need substantive literature that deals with all aspects of their chosen profession in order to meet the challenges of providing dental health care in the future. 相似文献
