Some peer reviewers may inappropriately, or coercively request that authors include references to the reviewers' own work. The objective of this study was to evaluate whether, compared to reviews for a journal with single-blind peer review, reviews for a journal with open peer review included (1) fewer self-citations; (2) a lower proportion of self-citations without a rationale; and (3) a lower ratio of proportions of citations without a rationale in self-citations versus citations to others' work. Peer reviews for published manuscripts submitted in 2012 to a single-blind peer review journal, the Journal of Psychosomatic Research, were previously evaluated (Thombs et al., 2015). These were compared to publically available peer reviews of manuscripts published in 2012 in an open review journal, BMC Psychiatry. Two investigators independently extracted data for both journals. There were no significant differences between journals in the proportion of all reviewer citations that were self-citations (Journal of Psychosomatic Research: 71/225, 32%; BMC Psychiatry: 90/315, 29%; p=.50), or in the proportion of self-citations without a rationale (Journal of Psychosomatic Research: 15/71, 21%; BMC Psychiatry: 12/90, 13%; p=.21). There was no significant difference between journals in the proportion of self-citations versus citations to others' work without a rationale (p=.31). Blind and open peer review methodologies have distinct advantages and disadvantages. The present study found that, in reasonably similar journals that use single-blind and open review, there were no substantive differences in the pattern of peer reviewer self-citations.

To conduct a bibliometric analysis of eating disorder journals to guide journal readers and researchers when submitting their manuscripts. Several indices were used to compare journal impact and citations of articles appearing between 1996 and 2010 in six eating disorders journals and six leading general psychiatry journals. The International Journal of Eating Disorders (IJED) had the highest journal impact factor (JIF, 2.278) of the six eating disorders' journals. The general psychiatry journals had higher JIFs and received more citations per eating disorder article than the specialized journals. However, IJED published the highest number of eating disorder articles between 1996 and 2010, and 35 of these articles received at least 100 citations. Using the JIF alone to decide where to submit a manuscript is a poor strategy, as this does not take into consideration the impact an article can have within the eating disorder's field over time.

Inaccurate Citations in Biomedical Journalism: Effect on the Impact Factor of the American Journal of Roentgenology.

PubMed

Karabulut, Nevzat

2017-03-01

The aim of this study is to investigate the frequency of incorrect citations and its effects on the impact factor of a specific biomedical journal: the American Journal of Roentgenology. The Cited Reference Search function of Thomson Reuters' Web of Science database (formerly the Institute for Scientific Information's Web of Knowledge database) was used to identify erroneous citations. This was done by entering the journal name into the Cited Work field and entering "2011-2012" into the Cited Year(s) field. The errors in any part of the inaccurately cited references (e.g., author names, title, year, volume, issue, and page numbers) were recorded, and the types of errors (i.e., absent, deficient, or mistyped) were analyzed. Erroneous citations were corrected using the Suggest a Correction function of the Web of Science database. The effect of inaccurate citations on the impact factor of the AJR was calculated. Overall, 183 of 1055 citable articles published in 2011-2012 were inaccurately cited 423 times (mean [± SD], 2.31 ± 4.67 times; range, 1-44 times). Of these 183 articles, 110 (60.1%) were web-only articles and 44 (24.0%) were print articles. The most commonly identified errors were page number errors (44.8%) and misspelling of an author's name (20.2%). Incorrect citations adversely affected the impact factor of the AJR by 0.065 in 2012 and by 0.123 in 2013. Inaccurate citations are not infrequent in biomedical journals, yet they can be detected and corrected using the Web of Science database. Although the accuracy of references is primarily the responsibility of authors, the journal editorial office should also define a periodic inaccurate citation check task and correct erroneous citations to reclaim unnecessarily lost credit.

Prestige versus citation volume as journal indices in cognitive neuroscience.

PubMed

Ward, Jamie

2014-01-01

In recent years, alternative measures of a journal's influence have been developed to those based on citation metrics (such as Impact Factor). This includes the Scimago Journal Rank (SJR) which is adapted from algorithms used to prioritize webpages in search engines. It is considered a measure of "prestige" insofar as it takes into account the importance of links/citations and not just their total number. Taking a sample of 38 journals from within the field of cognitive neuroscience, it is shown that SJR and Impact Factor correlate highly (r = .83) but with a few large discrepancies in rankings. This journal, Cognitive Neuroscience, fares better on the prestige-based measure than might otherwise be expected from its citation-based rank.

This study considered all articles published in six Public Library of Science (PLOS) journals in 2012 and Web of Science citations for these articles as of May 2015. A total of 2,406 articles were analyzed to examine the relationships between Altmetric Attention Scores (AAS) and Web of Science citations. The AAS for an article, provided by Altmetric aggregates activities surrounding research outputs in social media (news outlet mentions, tweets, blogs, Wikipedia, etc.). Spearman correlation testing was done on all articles and articles with AAS. Further analysis compared the stratified datasets based on percentile ranks of AAS: top 50%, top 25%, top 10%, and top 1%. Comparisons across the six journals provided additional insights. The results show significant positive correlations between AAS and citations with varied strength for all articles and articles with AAS (or social media mentions), as well as for normalized AAS in the top 50%, top 25%, top 10%, and top 1% datasets. Four of the six PLOS journals, Genetics, Pathogens, Computational Biology, and Neglected Tropical Diseases, show significant positive correlations across all datasets. However, for the two journals with high impact factors, PLOS Biology and Medicine, the results are unexpected: the Medicine articles showed no significant correlations but the Biology articles tested positive for correlations with the whole dataset and the set with AAS. Both journals published substantially fewer articles than the other four journals. Further research to validate the AAS algorithm, adjust the weighting scheme, and include appropriate social media sources is needed to understand the potential uses and meaning of AAS in different contexts and its relationship to other metrics.

To compare Spanish nursing journals with 2 English-language standard journals, as well as Spanish journals in closely related disciplines, to identify possible quantitative and qualitative shortcomings in scientific documentation. We performed a descriptive, cross-sectional study of the references contained in 796 articles from 6 Spanish journals from 3 health disciplines (2000-2002) and 2 English-language nursing journals (2000-2001). The number of references, type of publication cited, and language of the document cited were compared in individual journals, and in journals grouped by discipline and according to language. Spanish-language nursing journals had the lowest mean number of references per article (X- = 16.20) when compared with psychology journals (X- = 31.24), medical journals (X- = 31.39) and international nursing journals (X- = 37.11). Among Spanish journals, citation of English-language publications was most frequent in medical journals (X- = 26.28) and least frequent in nursing journals (X- = 6.04). In contrast, citation of Spanish documents was most frequent in nursing journals (X- = 9.79) and least frequent in medical journals (X- = 4.43). Although scientific publication of Spanish nursing has improved, it is not comparable to publication of closely related disciplines and international nursing. The low citation of English documents clearly reveals the risk of scientific insularity.

Citation analysis of mental health nursing journals: how should we rank thee?

The journal impact factor (JIF), and how best to rate the performance of a journal and the articles they contain, are areas of great debate. The aim of this paper was to assess various ranking methods of journal quality for mental health nursing journals, and to list the top 10 articles that have received the most number of citations to date. Seven mental health nursing journals were chosen for the analysis of citations they received in 2010, as well as their current impact factors from two sources, and other data for ranking purposes. There was very little difference in the top four mental health nursing journals and their overall rankings when combining various bibliometric indicators. That said, the International Journal of Mental Health Nursing is currently the highest ranked mental health nursing journal based on JIF, but publishes fewer articles per year compared to other journals. Overall, very few articles received 50 or more citations. This study shows that researchers need to consider more than one ranking method when deciding where to send or publish their research. © 2012 The Authors.

The impact factor (IF), as the most important criterion for journal's quality measurement, is affected by the self-citation and number of publications in each journal. To find out the relationship between the number of publications and self-citations in a journal, and their correlations with IF. Self-citations and impact factors of nine top gastroenterology and hepatology journals were assessed during the seven recent years (2005-2011) through Journal Citation Reports (JCR, ISI Thomson Reuters). Although impact factors of all journals increased during the study, five out of nine journals increased the number of publications from 2005 to 2011. There was an increase in self-citation only in the journal of HEPATOLOGY (499 in 2005 vs. 707 in 2011). Impact factors of journals (6.5 ± 3.5) were positively correlated with total number of publications (248.6 ± 91.7) (R: 0.688, P < 0.001). Besides, the self-citation rate (238.73 ± 195.317) was highly correlated with total number of publications in each journal (248.6 ± 91.7) (R: 0.861, P < 0.001). On the other hand, impact factor without self-citation (6.08 ± 3.3) had a correlation (R: 0.672, P < 0.001) with the number of published items (248.6 ± 91.7). The number of articles and self-citation have definite effects on IF of a journal and because IF is the most prominent criterion for journal's quality measurement, it would be a good idea to consider factors affecting on IF such as self-citation.

To analyze the 2007 citation count of articles published by the Croatian Medical Journal in 2005-2006 based on data from the Web of Science, Scopus, and Google Scholar. Web of Science and Scopus were searched for the articles published in 2005-2006. As all articles returned by Scopus were included in Web of Science, the latter list was the sample for further analysis. Total citation counts for each article on the list were retrieved from Web of Science, Scopus, and Google Scholar. The overlap and unique citations were compared and analyzed. Proportions were compared using chi(2)-test. Google Scholar returned the greatest proportion of articles with citations (45%), followed by Scopus (42%), and Web of Science (38%). Almost a half (49%) of articles had no citations and 11% had an equal number of identical citations in all 3 databases. The greatest overlap was found between Web of Science and Scopus (54%), followed by Scopus and Google Scholar (51%), and Web of Science and Google Scholar (44%). The greatest number of unique citations was found by Google Scholar (n=86). The majority of these citations (64%) came from journals, followed by books and PhD theses. Approximately 55% of all citing documents were full-text resources in open access. The language of citing documents was mostly English, but as many as 25 citing documents (29%) were in Chinese. Google Scholar shares a total of 42% citations returned by two others, more influential, bibliographic resources. The list of unique citations in Google Scholar is predominantly journal based, but these journals are mainly of local character. Citations received by internationally recognized medical journals are crucial for increasing the visibility of small medical journals but Google Scholar may serve as an alternative bibliometric tool for an orientational citation insight.

The authors, citations and content of European Journal of Engineering Education (EJEE) and Journal of Engineering Education (JEE) in 1973 (JEE, 1975 EJEE), 1983, 1993, 2003, and available 2013 issues were analysed. Both journals transitioned from house organs to become engineering education research (EER) journals, although JEE transitioned first. In this process the number of citations rose, particularly of education and psychology sources; the percentage of research articles increased markedly as did the number of reference disciplines. The number of papers per issue, the number of single author papers, and the citations of science and engineering sources decreased. EJEE has a very broad geographic spread of authors while JEE authors are mainly US based. A 'silo' mentality where general engineering education researchers do not communicate with EER researchers in different engineering disciplines is evident. There is some danger that EER may develop into a silo that does not communicate with technically oriented engineering professors.

Assessing the impact of individual journal articles provides information for understanding trends in science and translation of findings on practice. Citation analysis is an important way to highlight the contributions of individual author/investigator and journals on nursing practice. The purpose of this study was to identify the most frequently cited articles published in nursing journals from 1956 to 2011. The Science Citation Index Expanded and Social Sciences Citation Index were searched for citations through 2011 to articles published in the 89 nursing journals listed on the Journal Citation Reports (2010 edition). The number of citations, topic, countries, and institutions of origin based on the first author affiliation, year of publication, study design, publishing journal, journal country, and journal impact factor were noted. The most frequently cited articles published in the 89 nursing journals from 1956 to 2011 were identified. The top 50 most frequently cited articles were published in 10 nursing journals between 1970 and 2005. The top cited article received 784 citations. The most common topics were methodology for qualitative studies, validation procedures for tool development, and nursing care and practices in cancer and mental health. The most common study designs were reviews including meta-analysis and instrument validation. Most of the top 50 cited articles were published from 1986 to 1995. The findings provide insights into priorities and trends in nursing research and translational science.

Dentistry is a medical discipline with an increasing scientific production in the last years. Due to the importance of data sharing in science, this study aims at analyzing the availability of raw data in articles from scientific journals indexed in the Dentistry category of the 2014 edition of the Journal Citation Reports. A review of the 88 websites of journals from the Dentistry category was conducted to determine the data-sharing editorial policies. Furthermore, a search in the PubMed Central repository to collect information about the characteristics of the supplementary material of articles from those journals was carried out. The possibility of publishing a supplementary material was higher in the first quartile journals. A percentage of 7.6% of the articles registered in PubMed Central contained a supplementary material, especially text documents, but the presence of spreadsheets was scarce. There is a relationship between openness policies and the impact of the journals according to their quartile or position ranking by the impact factor in the JCR, but the willingness of sharing raw data in spreadsheets format is still limited. This study will reveal the resources of raw data which will improve quality of research and clinical practice.

The number of citations an article receives after its publication reflects its impact in the scientific community. The aim of this study was to identify and characterize the 100 top-cited articles published in radiology journals. The top-cited articles published in 12 radiology journals were identified using the database of Science Citation Index Expanded (1945-2012). The 100 top-cited articles were selected and analyzed with regard to the number of citations, year of publication, publishing journal, authorship, institution and country of origin, type of article, radiologic subspecialty, main topic, and radiologic technique. The 100 top-cited articles were published in eight radiology journals, led by Radiology (n=67) and followed by the American Journal of Roentgenology (n=11). These articles were published between 1939 and 2006 with a mean of 664.3 citations per article (range, 371-6931). Seventy-eight articles were published after 1979, 57 originated from the United States, and 69 were original articles. The most common subspecialties of study were interventional radiology (n=19), neuroradiology (n=15), and breast imaging (n=11). The main topics of articles were radiofrequency ablation of hepatic tumors (n=9), followed by receiver operating characteristic curves (n=6). Our study presents a detailed list and analysis of the 100 top-cited articles published in radiology journals, which provides insight into historical developments in the field of radiology.

Authors attain comparable or slightly higher rates of citation publishing in an open access journal (CytoJournal) compared to traditional cytopathology journals - A five year (2007-2011) experience

PubMed Central

Frisch, Nora K.; Nathan, Romil; Ahmed, Yasin K.; Shidham, Vinod B.

2014-01-01

Background: The era of Open Access (OA) publication, a platform which serves to better disseminate scientific knowledge, is upon us, as more OA journals are in existence than ever before. The idea that peer-reviewed OA publication leads to higher rates of citation has been put forth and shown to be true in several publications. This is a significant benefit to authors and is in addition to another relatively less obvious but highly critical component of the OA charter, i.e. retention of the copyright by the authors in the public domain. In this study, we analyzed the citation rates of OA and traditional non-OA publications specifically for authors in the field of cytopathology. Design: We compared the citation patterns for authors who had published in both OA and traditional non-OA peer-reviewed, scientific, cytopathology journals. Citations in an OA publication (CytoJournal) were analyzed comparatively with traditional non-OA cytopathology journals (Acta Cytologica, Cancer Cytopathology, Cytopathology, and Diagnostic Cytopathology) using the data from web of science citation analysis site (based on which the impact factors (IF) are calculated). After comparing citations per publication, as well as a time adjusted citation quotient (which takes into account the time since publication), we also analyzed the statistics after excluding the data for meeting abstracts. Results: Total 28 authors published 314 publications as articles and meeting abstracts (25 authors after excluding the abstracts). The rate of citation and time adjusted citation quotient were higher for OA in the group where abstracts were included (P < 0.05 for both). The rates were also slightly higher for OA than non-OA when the meeting abstracts were excluded, but the difference was statistically insignificant (P = 0.57 and P = 0.45). Conclusion We observed that for the same author, the publications in the OA journal attained a higher rate of citation than the publications in the traditional non

Bibliometrics of systematic reviews: analysis of citation rates and journal impact factors

PubMed Central

2013-01-01

Background Systematic reviews are important for informing clinical practice and health policy. The aim of this study was to examine the bibliometrics of systematic reviews and to determine the amount of variance in citations predicted by the journal impact factor (JIF) alone and combined with several other characteristics. Methods We conducted a bibliometric analysis of 1,261 systematic reviews published in 2008 and the citations to them in the Scopus database from 2008 to June 2012. Potential predictors of the citation impact of the reviews were examined using descriptive, univariate and multiple regression analysis. Results The mean number of citations per review over four years was 26.5 (SD ±29.9) or 6.6 citations per review per year. The mean JIF of the journals in which the reviews were published was 4.3 (SD ±4.2). We found that 17% of the reviews accounted for 50% of the total citations and 1.6% of the reviews were not cited. The number of authors was correlated with the number of citations (r = 0.215, P < 0.001). Higher numbers of citations were associated with the following characteristics: first author from the United States (36.5 citations), an ICD-10 chapter heading of Neoplasms (31.8 citations), type of intervention classified as Investigation, Diagnostics or Screening (34.7 citations) and having an international collaboration (32.1 citations). The JIF alone explained more than half of the variation in citations (R2 = 0.59) in univariate analysis. Adjusting for both JIF and type of intervention increased the R2 value to 0.81. Fourteen percent of reviews published in the top quartile of JIFs (≥ 5.16) received citations in the bottom quartile (eight or fewer), whereas 9% of reviews published in the lowest JIF quartile (≤ 2.06) received citations in the top quartile (34 or more). Six percent of reviews in journals with no JIF were also in the first quartile of citations. Conclusions The JIF predicted over half of the variation in citations to the

Aim To investigate the correlation between the length of the title of a scientific article and the number of citations it receives, in view of the common editorial call for shorter titles. Methods Title and the number of citations to all articles published in 2005 in 22 arbitrarily chosen English-language journals (n = 9031) were retrieved from citation database Scopus. The 2008 journal impact factors of these 22 journals were also retrieved from Thomson Reuters’ Journal Citation Report (JCR). Assuming the article title length as the independent variable, and the number of citations to the article as the dependent variable, a linear regression model was applied. Results The slope of the regression line for some journals (n = 6, when titles were measured in characters but 7 when titles were measured in words) was negative – none was significantly different from 0. The overall slope for all journals was 0.140 (when titles were measured in characters) and 0.778 (when titles were measured in words), significantly different from 0 (P < 0.001). Overall, articles with longer titles received more citations – Spearman ρ = 0.266 – when titles were measured in characters, and ρ = 0.244 when titles were measured in words (P < 0.001). This association was found for 7 of 8 journals with impact factor >10 and for 2 out of 14 journals with impact factor <10 (P < 0.001, Fisher exact test). Conclusion Longer titles seem to be associated with higher citation rates. This association is more pronounced for journals with high impact factors. Editors who insist on brief and concise titles should perhaps update the guidelines for authors of their journals and have more flexibility regarding the length of the title. PMID:20401960

Purpose: The research assesses the impact of online journals on citation patterns by examining whether researchers were more likely to limit the resources they cited to those journals available online rather than those only in print. Setting: Publications from a large urban university with a medical college at an urban location and at a smaller regional location were examined. The number of online journals available to authors on either campus was the same. The number of print journals available on the large campus was much greater than the print journals available at the small campus. Methodology: Searches by author affiliation from 1996 to 2005 were performed in the Web of Science to find all articles written by affiliated members in the college of medicine at the selected institution. Cited references from randomly selected articles were recorded, and the cited journals were coded into five categories based on their availability at the study institution: print only, print and online, online only, not owned, and dropped. Results were analyzed using SPSS. The age of articles cited for selected years as well as for 2006 and 2007 was also examined. Results: The number of journals cited each year continued to increase. On the large urban campus, researchers were not more likely to cite journals available online or less likely to cite journals only in print. At the regional location, at which the number of print-only journals was minimal, use of print-only journals significantly decreased. Conclusion/discussion: The citation of print-only journals by researchers with access to a library with a large print and electronic collection appeared to continue, despite the availability of potential alternatives in the online collection. Journals available in electronic format were cited more frequently in publications from the campus whose library had a small print collection, and the citation of journals available in both print and electronic formats generally increased over

Hunt, Glenn E; Cleary, Michelle; Walter, Garry

2010-01-01

There is considerable debate on the use and abuse of journal impact factors and on selecting the most appropriate indicator to assess research outcome for an individual or group of scientists. Internet searches using Web of Science and Scopus were conducted to retrieve citation data for an individual in order to calculate nine variants of Hirsch's h-index. Citations to articles published in a wide range of psychiatric journals in the periods 1995-99 and 2000-05 were analyzed using Web of Science. Comparisons were made between journal impact factor, h-index of citations from publication to 2008, and the proportion of articles cited at least 30 or 50 times. For up to 14 years post-publication, there was a strong positive relationship between journal impact factor and h-index for citations received. Journal impact factor was also compared to the percentage of articles cited at least 30 or 50 times-a comparison that showed wide variations between journals with similar impact factors. This study found that 40%-50% of the articles published in the top ten psychiatry journals ranked by impact factor acquire 30 to 50 citations within ten to fifteen years. Despite certain flaws and weaknesses, the h-index provides a better way to assess long-term performance of articles or authors than using a journal's impact factor, and it provides an alternative way to assess a journal's long-term ranking.

Objective Our study aimed to assess Turkish publications in Science Citation Index (SCI) and Science Citation Index Expanded (SCI-E) indexed journals in the field of ‘anaesthesiology’. Methods Journals related to ‘anaesthesiology’ in the Science Citation Index-Expanded database of ‘Thomson Reuter Web of Science’ were searched. The search engine of Institute for Scientific Information (ISI) Web of Science (WoS) was used in the advanced mode by typing ‘IS=ISSN number’ to identify publications in the journal. By typing ‘IS=ISSN number AND CU=Turkey’, Turkish papers on anaesthesiology were found. If Turkish and non-Turkish authors had collaborated, the article was included in the search when the corresponding author had provided a Turkey-based address. The catalogue information and statistics were used to determine Turkish publications as the percentage of total publications and the annual mean number of Turkish publications. In WoS, ‘SU=anesthesiology’ was used to determine the number, country, year and topic distributions of publications from 1975 to date and within the last 10 years. The citation numbers and h-indices were determined based on the country for publications within the last 10 years. Results From 1975 to the early 2000s Turkey was 20th in the list of countries with highest number of publications on anaesthesiology, however in the last 10 years Turkey moved up to 18th place. Its mean citation number has been 4.64, and it remains the 2nd lowest country pertaining to citations among the 22 countries with the most number of publications. According to the percentage of publications in the field of anaesthesiology, the journals with highest rate of Turkish publications were Revista Brasileira de Anestesiologia, European Journal of Anaesthesiology and Journal of Anesthesia. Conclusion In the field of anaesthesiology, the highest number of articles from Turkey was published in Revista Brasileira de Anestesiologia, European Journal of

The Korean Journal of Urology began to be published exclusively in English in 2010 and is indexed in PubMed Central/PubMed. This study analyzed a variety of citation indicators of the Korean Journal of Urology before and after 2010 to clarify the present position of the journal among the urology category journals. The impact factor, SCImago Journal Rank (SJR), impact index, Z-impact factor (ZIF, impact factor excluding self-citation), and Hirsch Index (H-index) were referenced or calculated from Web of Science, Scopus, SCImago Journal & Country Ranking, Korean Medical Citation Index (KoMCI), KoreaMed Synapse, and Google Scholar. Both the impact factor and the total citations rose rapidly beginning in 2011. The 2012 impact factor corresponded to the upper 84.9% in the nephrology-urology category, whereas the 2011 SJR was in the upper 58.5%. The ZIF in KoMCI was one fifth of the impact factor because there are only two other urology journals in KoMCI. Up to 2009, more than half of the citations in the Web of Science were from Korean researchers, but from 2010 to 2012, more than 85% of the citations were from international researchers. The H-indexes from Web of Science, Scopus, KoMCI, KoreaMed Synapse, and Google Scholar were 8, 10, 12, 9, and 18, respectively. The strategy of the language change in 2010 was successful from the perspective of citation indicators. The values of the citation indicators will continue to increase rapidly and consistently as the research achievement of authors of the Korean Journal of Urology increases.

Citation analysis as one of the most widely used methods of bibliometrics can be used for computing the various impact measures for scholars based on data from citation databases. Journal Citation Reports (JCR) from Thomson Reuters provides annual report in the form of impact factor (IF) for each journal. We aimed to evaluate the citation parameters of Hepatitis Monthly by JCR in 2010 and compare them with GS and Sc. All articles of Hepat Mon published in 2009 and 2008 which had been cited in 2010 in three databases including WoS, Sc and GS gathered in a spreadsheet. The IFs were manually calculated. Among the 104 total published articles the accuracy rates of GS and Sc in recording the total number of articles was 96% and 87.5%. There was a difference between IFs among the three databases (0.793 in ISI [Institute for Scientific Information], 0.945 in Sc and 0.85 GS). The missing rate of citations in ISI was 4% totally. Original articles were the main cited types, whereas, guidelines and clinical challenges were the least ones. None of the three databases succeed to record all articles published in the journal. Despite high sensitivity of GS comparing to Sc, it cannot be a reliable source for indexing since GS has lack of screening in the data collection and low specificity. Using an average of three IFs is suggested to find the correct IF. Editors should be more aware on the role of original articles in increasing IF and the potential efficacy of review articles in long term impact factor.

A technique to identify core journals for neurosurgery using citation scatter analysis and the Bradford distribution across neurosurgery journals.

Madhugiri, Venkatesh S; Ambekar, Sudheer; Strom, Shane F; Nanda, Anil

2013-11-01

The volume of scientific literature doubles approximately every 7 years. The coverage of this literature provided by online compendia is variable and incomplete. It would hence be useful to identify "core" journals in any field and validate whether the h index and impact factor truly identify the core journals in every subject. The core journals in every medical specialty would be those that provide a current and comprehensive coverage of the science in that specialty. Identifying these journals would make it possible for individual physicians to keep abreast of research and clinical progress. The top 10 neurosurgical journals (on the basis of impact factor and h index) were selected. A database of all articles cited in the reference lists of papers published in issues of these journals published in the first quarter of 2012 was generated. The journals were ranked based on the number of papers cited from each. This citation rank list was compared with the h index and impact factor rank lists. The rank list was also examined to see if the concept of core journals could be validated for neurosurgical literature using Bradford's law. A total of 22,850 papers spread across 2522 journals were cited in neurosurgical literature over 3 months. Although the top 10 journals were the same, irrespective of ranking criterion (h index, impact factor, citation ranking), the 3 rank lists were not congruent. The top 25% of cited articles obeyed the Bradford distribution; beyond this, there was a zone of increased scatter. Six core journals were identified for neurosurgery. The core journals for neurosurgery were identified to be Journal of Neurosurgery, Neurosurgery, Spine, Acta Neurochirurgica, Stroke, and Journal of Neurotrauma. A list of core journals could similarly be generated for every subject. This would facilitate a focused reading to keep abreast of current knowledge. Collated across specialties, these journals could depict the current status of medical science.

Although serial literature is extremely important to a library collection, it is also the source of many problems. Specialty journal selection is difficult, particularly for the librarian of a small or intermediate-size library that is not in a position to develop or maintain an exhaustive or inclusive collection in a particular field or discipline. Steadily increasing journal costs and recent economic trends necessitate establishment or reexamination of a periodical collection policy. In this investigation, the technique used analyzes citations assigned to medical subject headings (MeSH) and subheadings by indexers who prepare the MEDLARS data base. Citations have been retrieved by exploiting the on-line nature of the MEDLARS data base. A four-year time period is used to identify specialty journals in the area of nursing. Results given include a separate rank-order listing arranged by decreasing frequency of productivity for each MeSH term searched. A composite listing is given for the 16,355 unique citations retrieved. The approach illustrated and data presented may be useful in establishing library policy for questions of periodical subscription and setting of priorities for binding and microform purchases. The purpose of the approach described is to predict collection demand with efficiency and economy. PMID:974295

Do citations accumulate too slowly in the social sciences to be used to assess the quality of recent articles? I investigate whether this is the case using citation data for all articles in economics and political science published in 2006 and indexed in the Web of Science. I find that citations in the first two years after publication explain more than half of the variation in cumulative citations received over a longer period. Journal impact factors improve the correlation between the predicted and actual future ranks of journal articles when using citation data from 2006 alone but the effect declines sharply thereafter. Finally, more than half of the papers in the top 20% in 2012 were already in the top 20% in the year of publication (2006).

The main objective of the present study was to classify doctoral programs with Quality Mention in Psychology based on their scientific productivity. For this purpose, articles in the Web of Science published by professors teaching in these doctoral programs were analyzed. In addition, we analyzed scientific journals in which these professors tend to publish more papers and the evolution in the number of papers published until 2009. Results showed that the most productive doctoral program was the Neurosciences program at the University of Oviedo. This program showed a ratio of 40 articles--published in journals included in Journal Citation Reports--by each professor. In contrast, other programs did not reach a ratio of 10 articles per professor. Regarding journals, results showed that 9 out of the 20 most popular journals are Hispanic and a gradual increase in the number of published papers was also observed. Lastly, results and implications for quality assessment are discussed.

Bibliometric research has risen in popularity during recent years and an increasing number of investigations now have examined the nursing literature. Our article provides a comprehensive overview of citation-based research in the nursing profession, as well as a discussion of bibliometrics, journal impact factors, and international publishing trends. The debate on evidence-based practice and its potential influence and relevance for nursing scholars is also covered. Although journal performance indicators are, no doubt, important for the contemporary nursing academic, it is the core research skills and attributes that nursing scholars, academics, and educators will need to consider more carefully in future if the next generation of professional nurse researchers is to truly flourish.

Journal article overlap is defined as the same journal article being indexed by two or more services. Using journal references from seventy dissertations written in the preclinical sciences, the extent of journal article overlap among Index Medicus, Science Citation Index, Biological Abstracts, and Chemical Abstracts was examined. Of the 7,969 journal references cited, 92% were indexed by at least two of these services; 591 articles were covered by only one of the services, and 55 articles were not indexed. A discussion of the advantages and costs of journal article overlap is presented. PMID:6388693

The impact of a publication in a particular medical area is reflected by the number of times the article is included as a citation. It is not known, however, which articles are cited the most in primary care journals. In our study, we aimed to identify the 100 most cited articles in primary care medicine and analyze their characteristics.We searched the Science Citation Index Expanded for articles published in 18 primary care journals using the subject category "Primary health care." We identified 100 articles in primary health care that were the most cited. We analyzed the characteristics of these articles using the title, number of citations, citation density, year of publication, journal source, decade published, country of origin, institution, author names, and type of article.The 100 articles that were cited the most were published between the years 1977 and 2009. The 1990s decade was the most productive decade. The number of citations ranged from 117 to 775. The articles were published in 9 journals and the journal with the largest number of most cited articles (n = 33) was the Journal of Family Practice. This was followed by the British Journal of General Practice (n = 17) and the journal Family Practice (n = 16). The United States was the most productive country (n = 59); the United Kingdom was next (n = 25) and this was followed by Canada (n = 5) and The Netherlands (n = 5). The most popular article type was a review article and this was followed by a qualitative study and then methodological study.Our study provides insight into the historical development of primary care studies, based on citations, and provides the foundation for further investigations.

2007-07-01

The paper describes the information needs of a state public health agency, compares needs to its library's collection, and evaluates collection development policy accordingly. A citation analysis of journal articles authored by Minnesota Department of Health staff as well as official publications from 2002 to 2004 was conducted. Fifty-six publications fitting the criteria for inclusion in the study were identified using PubMed and library records. Information on each cited reference was recorded, including reference type, relative age of citation, and journal name, if applicable. The library's collection and collection development policies were analyzed in regard to the results. As expected, journals were the most heavily cited format: 63% (n = 897) of all citations were to journal articles. Most cited materials were between 2 and 5 years old. The 897 journal citations represented 265 different journals. The top 10 cited journals (4% of all titles) accounted for 36% (n = 320) of all citations; 62% (n = 320) of journals were cited only once. Of the total journals cited, the library subscribed to 70% (n = 627). Overall, no large gaps appeared in the RN Barr Library's journal collection. The analysis confirms that the library's collections budget for serials and books reflects the cited use of these materials.

An Analysis of Peer-Reviewed Scores and Impact Factors with Different Citation Time Windows: A Case Study of 28 Ophthalmologic Journals.

2015-01-01

An important attribute of the traditional impact factor was the controversial 2-year citation window. So far, several scholars have proposed using different citation time windows for evaluating journals. However, there is no confirmation whether a longer citation time window would be better. How did the journal evaluation effects of 3IF, 4IF, and 6IF comparing with 2IF and 5IF? In order to understand these questions, we made a comparative study of impact factors with different citation time windows with the peer-reviewed scores of ophthalmologic journals indexed by Science Citation Index Expanded (SCIE) database. The peer-reviewed scores of 28 ophthalmologic journals were obtained through a self-designed survey questionnaire. Impact factors with different citation time windows (including 2IF, 3IF, 4IF, 5IF, and 6IF) of 28 ophthalmologic journals were computed and compared in accordance with each impact factor's definition and formula, using the citation analysis function of the Web of Science (WoS) database. An analysis of the correlation between impact factors with different citation time windows and peer-reviewed scores was carried out. Although impact factor values with different citation time windows were different, there was a high level of correlation between them when it came to evaluating journals. In the current study, for ophthalmologic journals' impact factors with different time windows in 2013, 3IF and 4IF seemed the ideal ranges for comparison, when assessed in relation to peer-reviewed scores. In addition, the 3-year and 4-year windows were quite consistent with the cited peak age of documents published by ophthalmologic journals. Our study is based on ophthalmology journals and we only analyze the impact factors with different citation time window in 2013, so it has yet to be ascertained whether other disciplines (especially those with a later cited peak) or other years would follow the same or similar patterns. We designed the survey questionnaire

[Scientific collaboration and article citations: practices in medical journals].

PubMed

Bador, Pascal; Lafouge, Thierry

2012-01-01

In order to characterize scientific collaboration the best way is to study co-signature of articles. Two indicators are interesting: number of authors and international character. The objective is to study correlation between these two indicators and citation number. We selected two pharmacy and medicine journals in order to compare practices. We used a sample of about 800 articles published in 2002-2005 for which we collected citations up to 2010. We transformed numeric variables, authors number and citation number, into qualitative variables. "Authors" and "Citations" variables are not independent. Less cited articles are often published by one author or a very small team while international character of articles generally increases citation number. This micro-analysis also allowed us to better understand publication practices. © 2012 Société Française de Pharmacologie et de Thérapeutique.

2015-09-01

In this study, the impact of self-citation (Journal and Author) on impact factor of Iranian English Medical journals in two international citation databases, Web of Science (WoS) and Islamic world science citation center (ISC), were compared by citation analysis. Twelve journals in WoS and 26 journals in ISC databases indexed between the years (2006-2009) were selected and compared. For comparison of self-citation rate in two databases, we used Wilcoxon and Mann-whitney tests. We used Pearson test for correlation of self-citation and IF in WoS, and the Spearman's correlation coefficient for the ISC database. Covariance analysis was used for comparison of two correlation tests. P. value was 0.05 in all of tests. There was no significant difference between self-citation rates in two databases (P>0.05). Findings also showed no significant difference between the correlation of Journal self-citation and impact factor in two databases (P=0.526) however, there was significant difference between the author's self-citation and impact factor in these databases (P<0.001). The impact of Author's self-citation in the Impact Factor of WoS was higher than the ISC.

Open access (OA) publishing, whereby authors, their institutions, or their granting bodies pay or provide a repository through which peer-reviewed work is available online for free, is championed as a model to increase the number of citations per paper and disseminate results widely, especially to researchers in developing countries. We compared the number of citations of OA and non-OA papers in six journals and four books published since 2000 to test whether OA increases number of citations overall and increases citations made by authors in developing countries. After controlling for type of paper (e.g., review or research paper), length of paper, authors' citation profiles, number of authors per paper, and whether the author or the publisher released the paper in OA, OA had no statistically significant influence on the overall number of citations per journal paper. Journal papers were cited more frequently if the authors had published highly cited papers previously, were members of large teams of authors, or published relatively long papers, but papers were not cited more frequently if they were published in an OA source. Nevertheless, author-archived OA book chapters accrued up to eight times more citations than chapters in the same book that were not available through OA, perhaps because there is no online abstracting service for book chapters. There was also little evidence that journal papers or book chapters published in OA received more citations from authors in developing countries relative to those journal papers or book chapters not published in OA. For scholarly publications in conservation biology, only book chapters had an OA citation advantage, and OA did not increase the number of citations papers or chapters received from authors in developing countries.

Background: In this study, the impact of self-citation (Journal and Author) on impact factor of Iranian English Medical journals in two international citation databases, Web of Science (WoS) and Islamic world science citation center (ISC), were compared by citation analysis. Methods: Twelve journals in WoS and 26 journals in ISC databases indexed between the years (2006–2009) were selected and compared. For comparison of self-citation rate in two databases, we used Wilcoxon and Mann-whitney tests. We used Pearson test for correlation of self-citation and IF in WoS, and the Spearman’s correlation coefficient for the ISC database. Covariance analysis was used for comparison of two correlation tests. P. value was 0.05 in all of tests. Results: There was no significant difference between self-citation rates in two databases (P>0.05). Findings also showed no significant difference between the correlation of Journal self-citation and impact factor in two databases (P=0.526) however, there was significant difference between the author’s self-citation and impact factor in these databases (P<0.001). Conclusion: The impact of Author’s self-citation in the Impact Factor of WoS was higher than the ISC. PMID:26587498

This article reviews the nature and use of the journal impact factor and other common bibliometric measures for assessing research in the sciences and social sciences based on data compiled by Thomson Reuters. Journal impact factors are frequently misused to assess the influence of individual papers and authors, but such uses were never intended. Thomson Reuters also employs other measures of journal influence, which are contrasted with the impact factor. Finally, the author comments on the proper use of citation data in general, often as a supplement to peer review. This review may help government policymakers, university administrators, and individual researchers become better acquainted with the potential benefits and limitations of bibliometrics in the evaluation of research.

Background An important attribute of the traditional impact factor was the controversial 2-year citation window. So far, several scholars have proposed using different citation time windows for evaluating journals. However, there is no confirmation whether a longer citation time window would be better. How did the journal evaluation effects of 3IF, 4IF, and 6IF comparing with 2IF and 5IF? In order to understand these questions, we made a comparative study of impact factors with different citation time windows with the peer-reviewed scores of ophthalmologic journals indexed by Science Citation Index Expanded (SCIE) database. Methods The peer-reviewed scores of 28 ophthalmologic journals were obtained through a self-designed survey questionnaire. Impact factors with different citation time windows (including 2IF, 3IF, 4IF, 5IF, and 6IF) of 28 ophthalmologic journals were computed and compared in accordance with each impact factor’s definition and formula, using the citation analysis function of the Web of Science (WoS) database. An analysis of the correlation between impact factors with different citation time windows and peer-reviewed scores was carried out. Results Although impact factor values with different citation time windows were different, there was a high level of correlation between them when it came to evaluating journals. In the current study, for ophthalmologic journals’ impact factors with different time windows in 2013, 3IF and 4IF seemed the ideal ranges for comparison, when assessed in relation to peer-reviewed scores. In addition, the 3-year and 4-year windows were quite consistent with the cited peak age of documents published by ophthalmologic journals. Research Limitations Our study is based on ophthalmology journals and we only analyze the impact factors with different citation time window in 2013, so it has yet to be ascertained whether other disciplines (especially those with a later cited peak) or other years would follow the same or

The study analyzes the relationship between the number of citations as calculated by the IN-RECS database and the quality evaluated by experts. The articles published in journals of the Spanish Psychological Association between 1996 and 2008 and selected by the Editorial Board of Psychology in Spain were the subject of the study. Psychology in Spain is a journal that includes the best papers published throughout the previous year, chosen by the Editorial Board made up of fifty specialists of acknowledged prestige within Spanish psychology and translated into English. The number of the citations of the 140 original articles republished in Psychology in Spain was compared to the number of the citations of the 140 randomly selected articles. Additionally, the study searched for a relationship between the number of the articles selected from each journal and their mean number of citations. The number of citations received by the best articles as evaluated by experts is significantly higher than the number of citations of the randomly selected articles. Also, the number of citations is higher in the articles from the most frequently selected journals. A statistically significant relation between the quality evaluated by experts and the number of the citations was found.

To explore academic significance and guiding function played by subspecialty groups of the Society of Pediatrics, Chinese Medical Association on Chinese pediatric clinical practice through a statistical analysis of the articles published by the subspecialty groups. Bibliometric methods were used to analyze the number of articles, article types, total citations, highly cited articles and the distribution of citing journals. Totally 7 156 articles were published in Chinese Journal of Pediatrics from 1993 (31) to 2012 (51), of which 187 by subspecialty groups of pediatrics (2.6%), with a total citations of 11 985. Among them, 137 articles were cited with a citation rate of 73.3% and average citations for each article was 64.1. Articles classified as clinical guidelines had been totally cited for 10 900 times with average citations of 123.86 per article. The article on Neonatal hypoxic ischemic encephalopathy diagnosis and clinical index was cited 1 791 times ranked in highly cited literatures. All the top three cited literature periodicals were core journals of pediatrics, and 10 periodicals among the top 20 were in pediatrics and the rest in other medical fields. The number of the articles published by the subspecialty groups of pediatrics was increasing year by year though the portion it in the total number of the articles in the journal was not large. However, the citation frequency of the articles by the subspecialty groups of pediatrics was high, making an obvious contribution to the total citations of Chinese Journal of Pediatrics. The total citation rate of clinical guideline articles and their average rate was higher than those of other articles published in this journal, which meant that this type of articles provided academic references with guiding significance for clinical practice of pediatrics and for other medical fields as well.

The Korean Journal of Internal Medicine (KJIM) is the international journal published in English by the Korean Association of Internal Medicine. To understand the position of the journal in three different databases, the citation indicators were elucidated. From databases such as Korean Medical Citation Index (KoMCI), Web of Science, and Scopus, citation indicators such as the impact factor, SCImago journal rank (SJR), or Hirsch Index were calculated according to the year and the results were drawn. The KJIM 2010 impact factor increased to 0.623 in Web of Science. That of year 2009 in KoMCI was a 0.149. The 2009 SJR in Scopus was 0.073, with a ranking of 27/72 (37.5%) in the category of internal medicine and 414/1,618 (25.6%) in the category of medicine, miscellaneous. The Hirsch Index from KoMCI, Web of Science and Scopus were 5, 14, and 16, respectively. The KJIM is now cited more by international researchers than Korean researchers, indicating that the content of the journal is now valued at the international level. PMID:21437155

Citation tracking is an important method to analyze the scientific impact of journal articles and can be done through Scopus (SC), Google Scholar (GS), or ISI web of knowledge (WOS). In the current study, we analyzed the citations to 2011-2012 articles of Iranian Journal of Basic Medical Sciences (IJBMS) in these three resources. The relevant data from SC, GS, and WOS official websites. Total number of citations, their overlap and unique citations of these three recourses were evaluated. WOS and SC covered 100% and GS covered 97% of the IJBMS items. Totally, 37 articles were cited at least once in one of the studied resources. Total number of citations were 20, 30, and 59 in WOS, SC, and GS respectively. Forty citations of GS, 6 citation of SC, and 2 citations of WOS were unique. Every scientific resource has its own inaccuracies in providing citation analysis information. Citation analysis studies are better to be done each year to correct any inaccuracy as soon as possible. IJBMS has gained considerable scientific attention from wide range of high impact journals and through citation tracking method; this visibility can be traced more thoroughly.

2013-01-01

Background In times of globalization there is an increasing use of English in the medical literature. The aim of this study was to analyze the influence of English-language articles in multi-language medical journals on their international recognition – as measured by a lower rate of self-citations and higher impact factor (IF). Methods and Findings We analyzed publications in multi-language journals in 2008 and 2009 using the Web of Science (WoS) of Thomson Reuters (former Institute of Scientific Information) and PubMed as sources of information. The proportion of English-language articles during the period was compared with both the share of self-citations in the year 2010 and the IF with and without self-citations. Multivariable linear regression analysis was performed to analyze these factors as well as the influence of the journals‘ countries of origin and of the other language(s) used in publications besides English. We identified 168 multi-language journals that were listed in WoS as well as in PubMed and met our criteria. We found a significant positive correlation of the share of English articles in 2008 and 2009 with the IF calculated without self-citations (Pearson r=0.56, p = <0.0001), a correlation with the overall IF (Pearson r = 0.47, p = <0.0001) and with the cites to years of IF calculation (Pearson r = 0.34, p = <0.0001), and a weak negative correlation with the share of self-citations (Pearson r = -0.2, p = 0.009). The IF without self-citations also correlated with the journal‘s country of origin – North American journals had a higher IF compared to Middle and South American or European journals. Conclusion Our findings suggest that a larger share of English articles in multi-language medical journals is associated with greater international recognition. Fewer self-citations were found in multi-language journals with a greater share of original articles in English. PMID:24146929

Betweenness and diversity in journal citation networks as measures of interdisciplinarity-A tribute to Eugene Garfield.

PubMed

Leydesdorff, Loet; Wagner, Caroline S; Bornmann, Lutz

2018-01-01

Journals were central to Eugene Garfield's research interests. Among other things, journals are considered as units of analysis for bibliographic databases such as the Web of Science and Scopus. In addition to providing a basis for disciplinary classifications of journals, journal citation patterns span networks across boundaries to variable extents. Using betweenness centrality (BC) and diversity, we elaborate on the question of how to distinguish and rank journals in terms of interdisciplinarity. Interdisciplinarity, however, is difficult to operationalize in the absence of an operational definition of disciplines; the diversity of a unit of analysis is sample-dependent. BC can be considered as a measure of multi-disciplinarity. Diversity of co-citation in a citing document has been considered as an indicator of knowledge integration, but an author can also generate trans-disciplinary-that is, non-disciplined-variation by citing sources from other disciplines. Diversity in the bibliographic coupling among citing documents can analogously be considered as diffusion  or differentiation of knowledge across disciplines. Because the citation networks in the cited direction reflect both structure and variation, diversity in this direction is perhaps the best available measure of interdisciplinarity at the journal level. Furthermore, diversity is based on a summation and can therefore be decomposed; differences among (sub)sets can be tested for statistical significance. In the appendix, a general-purpose routine for measuring diversity in networks is provided.

How to Rank Journals

There are now many methods available to assess the relative citation performance of peer-reviewed journals. Regardless of their individual faults and advantages, citation-based metrics are used by researchers to maximize the citation potential of their articles, and by employers to rank academic track records. The absolute value of any particular index is arguably meaningless unless compared to other journals, and different metrics result in divergent rankings. To provide a simple yet more objective way to rank journals within and among disciplines, we developed a κ-resampled composite journal rank incorporating five popular citation indices: Impact Factor, Immediacy Index, Source-Normalized Impact Per Paper, SCImago Journal Rank and Google 5-year h-index; this approach provides an index of relative rank uncertainty. We applied the approach to six sample sets of scientific journals from Ecology (n = 100 journals), Medicine (n = 100), Multidisciplinary (n = 50); Ecology + Multidisciplinary (n = 25), Obstetrics & Gynaecology (n = 25) and Marine Biology & Fisheries (n = 25). We then cross-compared the κ-resampled ranking for the Ecology + Multidisciplinary journal set to the results of a survey of 188 publishing ecologists who were asked to rank the same journals, and found a 0.68–0.84 Spearman’s ρ correlation between the two rankings datasets. Our composite index approach therefore approximates relative journal reputation, at least for that discipline. Agglomerative and divisive clustering and multi-dimensional scaling techniques applied to the Ecology + Multidisciplinary journal set identified specific clusters of similarly ranked journals, with only Nature & Science separating out from the others. When comparing a selection of journals within or among disciplines, we recommend collecting multiple citation-based metrics for a sample of relevant and realistic journals to calculate the composite rankings and their relative uncertainty windows.

Abstract Scholarly publishing and citation practices have developed largely in the absence of versioned documents. The digital age requires new practices to combine the old and the new. We describe how the original published source and a versioned wiki page based on it can be reconciled and combined into a single citation reference. We illustrate the citation mechanism by way of practical examples focusing on journal and wiki publishing of taxon treatments. Specifically, we discuss mechanisms for permanent cross-linking between the static original publication and the dynamic, versioned wiki, as well as for automated export of journal content to the wiki, to reduce the workload on authors, for combining the journal and the wiki citation and for integrating it with the attribution of wiki contributors.

Measures of health sciences journal use: a comparison of vendor, link-resolver, and local citation statistics.

Libraries require efficient and reliable methods to assess journal use. Vendors provide complete counts of articles retrieved from their platforms. However, if a journal is available on multiple platforms, several sets of statistics must be merged. Link-resolver reports merge data from all platforms into one report but only record partial use because users can access library subscriptions from other paths. Citation data are limited to publication use. Vendor, link-resolver, and local citation data were examined to determine correlation. Because link-resolver statistics are easy to obtain, the study library especially wanted to know if they correlate highly with the other measures. Vendor, link-resolver, and local citation statistics for the study institution were gathered for health sciences journals. Spearman rank-order correlation coefficients were calculated. There was a high positive correlation between all three data sets, with vendor data commonly showing the highest use. However, a small percentage of titles showed anomalous results. Link-resolver data correlate well with vendor and citation data, but due to anomalies, low link-resolver data would best be used to suggest titles for further evaluation using vendor data. Citation data may not be needed as it correlates highly with other measures.

The number of citations received is considered an index of study quality and impact. We aimed to examine the factors associated with the number of citations of published articles, focusing on the article length. Original human studies published in the first trimester of 2006 in 5 major General Medicine journals were analyzed with regard to the number of authors and of author-affiliated institutions, title and abstract word count, article length (number of print pages), number of bibliographic references, study design, and 2006 journal impact factor (JIF). A multiple linear regression model was employed to identify the variables independently associated with the number of article citations received through January 2012. On univariate analysis the JIF, number of authors, article length, study design (interventional/observational and prospective/retrospective), title and abstract word count, number of author-affiliated institutions, and number of references were all associated with the number of citations received. On multivariate analysis with the logarithm of citations as the dependent variable, only article length [regression coefficient: 14.64 (95% confidence intervals: (5.76-23.50)] and JIF [3.37 (1.80-4.948)] independently predicted the number of citations. The variance of citations explained by these parameters was 51.2%. In a sample of articles published in major General Medicine journals, in addition to journal impact factors, article length and number of authors independently predicted the number of citations. This may reflect a higher complexity level and quality of longer and multi-authored studies.

The extent to which articles are cited is a surrogate of the impact and importance of the research conducted; poorly cited articles may identify research of limited use and potential wasted investments. We assessed trends in the rates of poorly cited articles and journals in the cardiovascular literature from 1997 to 2007. We identified original articles published in cardiovascular journals and indexed in the Scopus citation database from 1997 to 2007. We defined poorly cited articles as those with ≤5 citations in the 5 years following publication and poorly cited journals as those with >75% of journal content poorly cited. We identified 164 377 articles in 222 cardiovascular journals from 1997 to 2007. From 1997 to 2007, the number of cardiovascular articles and journals increased by 56.9% and 75.2%, respectively. Of all the articles, 75 550 (46.0%) were poorly cited, of which 25 650 (15.6% overall) had no citations. From 1997 to 2007, the proportion of poorly cited articles declined slightly (52.1%-46.2%, trend P<0.001), although the absolute number of poorly cited articles increased by 2595 (trend P<0.001). At a journal level, 44% of cardiovascular journals had more than three-fourths of the journal's content poorly cited at 5 years. Nearly half of all peer-reviewed articles published in cardiovascular journals are poorly cited 5 years after publication, and many are not cited at all. The cardiovascular literature and the number of poorly cited articles both increased substantially from 1997 to 2007. The high proportion of poorly cited articles and journals suggests inefficiencies in the cardiovascular research enterprise. © 2015 American Heart Association, Inc.

The International Journal of Occupational Medicine and Environmental Health (IJOMEH) is an international professional quarterly focused on such areas as occupational medicine, toxicology and environmental health edited in Poland. IJOMEH, published in English, is indexed in numerous world information services (MEDLINE, EMBASE, EBSCO, SCOPUS). This paper presents the contribution of IJOMEH publications to the world circulation of scientific information based on the citation analysis. The analysis, grounded on the SCOPUS database, assessed the frequency of citations in the years 1996-2005. Journals in which they have been cited were retrieved and their list is also included.

Performance of Malaysian Medical Journals

Indexation status matters for scholarly journal prestige and trust. The performance of Malaysian medical journals at the international level is gauged through the global citation databases, and at the national level through MyCite, a national citation indexing system. The performance indicators include journals publication productivity, the citations they garner, and their scores on other bibliometric indices such as journal impact factor (IF), and h-index. There is a growing consciousness amongst journal editorials to improve quality and increase chances of getting indexed in MyCite. Although it is now possible to gauge journal performance within Malaysia, through MyCite, the government and public are concerned about journal performance in international databases. Knowing the performance of journals in MyCite will help the editors and publishers to improve the quality and visibility of Malaysian journals and strategise to bring their journal to the international level of indexation.

Top of the charts: download versus citations in the International Journal of Cardiology.

Coats, Andrew J S

2005-11-02

The medical literature is growing at an alarming rate. Research assessment exercises, research quality frameworks, league tables and the like have attempted to quantify the volume, quality and impact of research. Yet the established measures (such as citation rates) are being challenged by the sheer number of journals, variability in the "gold standard" of peer-review and the emergence of open-source or web-based journals. In the last few years, we have seen a growth in downloads to individual journal articles that now easily exceeds formal journal subscriptions. We have recorded the 10 top cited articles over a 12-month period and compared them to the 10 most popular articles being downloaded over the same time period. The citation-based listing included basic and applied, observational and interventional original research reports. For downloaded articles, which have shown a dramatic increase for the International Journal of Cardiology from 48,000 in 2002 to 120,000 in 2003 to 200,000 in 2004, the most popular articles over the same period are very different and are dominated by up-to-date reviews of either cutting-edge topics (such as the potential of stem cells) or of the management of rare or unusual conditions. There is no overlap between the two lists despite covering exactly the same 12-month period and using measures of peer esteem. Perhaps the time has come to look at the usage of articles rather than, or in addition to, their referencing.

2012-01-01

Introduction: Citation analysis is currently one of the most widely used metrics for analyzing the scientific contribution in different fields. The Islamic World Science Citation Center (ISC) aims at promoting technical cooperation among Muslim scientists and their respected centers based on these theories. It also facilitates the accessibility of knowledge and research contribution among them. This paper aims at revealing some of the outmost features of ISC databases, in order to give a fairly clear view of what it is and what are its products. The paper consists of three major parts. After an introduction about the Islamic World Science Citation Center, the paper deals with major tools and products of ISC. In the third part ISCs’ journal Submission system is presented as an automatic means, by which users can upload journals’ papers into the respected databases. Conclusion: Some complementary remarks have been made regarding the current state of ISC and its future plans. PMID:23322953

The purpose of this study was to identify and examine the top 100 most highly cited articles of all time as well as the 25 most highly cited articles of the last decade from within 5 school psychology journals: Journal of School Psychology, Psychology in the Schools, School Psychology International, School Psychology Quarterly, and School Psychology Review. The Institute for Scientific Information Web of Science database was utilized to identify citation counts for each article appearing in these journals. Coding schemes were used to identify article type and content area. The top 10 most highly cited articles of all time as well as the top 10 most highly cited articles of the past decade are detailed, and general patterns found across these articles are discussed. Implications for reviewing manuscripts that are likely to become highly cited articles and for authoring a highly cited article are offered. Copyright © 2011. Published by Elsevier Ltd.

Measures of health sciences journal use: a comparison of vendor, link-resolver, and local citation statistics*

De Groote, Sandra L.; Blecic, Deborah D.; Martin, Kristin

2013-01-01

Objective: Libraries require efficient and reliable methods to assess journal use. Vendors provide complete counts of articles retrieved from their platforms. However, if a journal is available on multiple platforms, several sets of statistics must be merged. Link-resolver reports merge data from all platforms into one report but only record partial use because users can access library subscriptions from other paths. Citation data are limited to publication use. Vendor, link-resolver, and local citation data were examined to determine correlation. Because link-resolver statistics are easy to obtain, the study library especially wanted to know if they correlate highly with the other measures. Methods: Vendor, link-resolver, and local citation statistics for the study institution were gathered for health sciences journals. Spearman rank-order correlation coefficients were calculated. Results: There was a high positive correlation between all three data sets, with vendor data commonly showing the highest use. However, a small percentage of titles showed anomalous results. Discussion and Conclusions: Link-resolver data correlate well with vendor and citation data, but due to anomalies, low link-resolver data would best be used to suggest titles for further evaluation using vendor data. Citation data may not be needed as it correlates highly with other measures. PMID:23646026

The purpose of the study was to analyze the determinants of citations such as publication year, article type, article topic, article selected for a press release, number of articles previously published by the corresponding author, and publication language in a Spanish journal of public health. Observational study including all articles published in Gaceta Sanitaria during 2007-2011. We retrieved the number of citations from the ISI Web of Knowledge database in June 2013 and also information on other variables such as number of articles published by the corresponding author in the previous 5 years (searched through PubMed), selection for a press release, publication language, article type and topic, and others. We included 542 articles. Of these, 62.5% were cited in the period considered. We observed an increased odds ratio of citations for articles selected for a press release and also with the number of articles published previously by the corresponding author. Articles published in English do not seem to increase their citations. Certain externalities such as number of articles published by the corresponding author and being selected for a press release seem to influence the number of citations in national journals.

This study was designed to investigate the influence of journals indexed by Science Citation Index (SCI) on Chinese medical journals. Articles on medicine written by Chinese and the journals that published these articles from 2000 to 2009 were searched using Science Citation Index Expanded (SCI-E) database, and the status and variation tendency of the impact factors (IF) of these journals were analyzed. Data of articles on medicine included Chinese Scientific and Technical Paper and Citations Data (CSTPCD) from 2000 to 2008 were searched (the data of 2009 have not been released). The included articles and the time-dependent changing profile were studied. These outcomes were evaluated as the fixed base relative or link relative when compared with the data of 2000 or those of last year, respectively. Geometric mean was used when mean increase was calculated and IF distribution was described with median. Totally 3774 articles from China were published by journals indexed by SCI-E in 2000, and the number of articles published by Chinese authors increased every year. In 2008, 16 714 articles were indexed by SCI-E, 442.87% higher than those of 2000. The increment was 161.54% higher than that of articles published in the journals indexed by CSTPCD (281.33%) during the same period. From 2000 to 2009, the geometric mean of increase in the number of published articles from China in journals indexed by SCI-E was 20.87% but it was 18.21% in CSTPCD. From 2000 to 2009, the median of IF of SCI-E indexed journals that published Chinese medical articles was 1.866, 2.073, 2.390, 2.702, 2.409, 2.496, 2.380, 2.218, 2.280 and 2.331, respectively, and they did not increase or even decreased. The number of the articles indexed by SCI-E increased year by year, much faster than that of CSTPCD. However, it does not necessarily mean the increase in impact.

Recent years have seen numerous efforts and resources devoted to the development of open access (OA), but the current OA situation of the oncology literature remains unknown. We conducted this cross-sectional study to determine the current share and provision methods of OA in the field of oncology, identify predictors of OA status (OA versus non-OA), and study the association between OA and citation counts. PubMed was searched for oncology-related, peer-reviewed journal articles published in December 2014. Google, Google Scholar, PubMed, ResearchGate, OpenDOAR and OAIster were manually checked to assess the OA status of each included article. Citation data were extracted from Web of Science, Scopus and Google Scholar. Descriptive statistics were used to summarize the OA proportion (primary outcome) and OA provision methods. Multivariable logistic regression and multilevel generalized linear model analyses were performed to study predictors of OA status and the association between OA and citation counts, respectively. In a random sample of 1000 articles, 912 were deemed eligible and therefore included. Of these, the full-texts of 530 articles (58.1%; 95% CI: 54.9-61.3) were freely available online: 314 (34.4%) were available from publishers ('Gold road' to OA), 424 (46.5%) were available via self-archiving ('Green road' to OA). According to multivariable regression analyses, impact factor, publisher type, language, research type, number of authors, continent of origin, and country income were significant predictors of articles' OA status; OA articles received a citation rate 1.24 times the incidence rate for non-OA articles (95% CI: 1.05-1.47; P = 0.012). Based on our sample, in the field of oncology, 42% of recent journal articles are behind the pay-wall (non-OA) 1 year after publication; the 'Green road' of providing OA is more common than the 'Gold road'; OA is associated with higher citation counts. © The Author 2017.

The purpose of this study is to introduce a new methodology in the field of substance abuse, namely, co-citation analysis, which uses the bibliographic references of publications to establish the main thematic areas being researched and to identify the seminal documents that have contributed to establishing the intellectual foundation of the discipline at the present time. We identified all bibliographic references that were cited in documents published in the substance abuse journals included in the Journal Citation Reports in the 2001-2012 period, generating a co-citation matrix. This matrix was used to perform a co-citation network analysis. The co-citation network analysis led to the identification of 56 prominent research clusters that bring together 698 documents; their subject matter constitutes the foundation of the discipline in the field's journals. Substance abuse research is dominated by a few core topics; chief among them are tools for measuring and diagnosing dependence, as well as therapeutic approaches to treat alcohol abuse and nicotine addiction. Other areas of note include epidemiological studies, research on drug user motivation (particularly among young people), binge drinking, social support mediators and networks, opioid dependence, consumption and effects of cannabis, basic research on brain damage, genetic factors associated with substance use, and the physiological and neurological determinants of abstinence syndrome. The main works of reference that we identified were published in a small number of journals, which establish the intellectual, conceptual, and methodological basis of the discipline.

2017-12-01

The objective of our study was to investigate radiology manuscript characteristics that influence citation rate, capturing features of manuscript construction that are discrete from study design. Consecutive articles published from January 2004 to June 2004 were collected from the six major radiology journals with the highest impact factors: Radiology (impact factor, 5.076), Investigative Radiology (2.320), American Journal of Neuroradiology (AJNR) (2.384), RadioGraphics (2.494), European Radiology (2.364), and American Journal of Roentgenology (2.406). The citation count for these articles was retrieved from the Web of Science, and 29 article characteristics were tabulated manually. A point-biserial correlation, Spearman rank-order correlation, and multiple regression model were performed to predict citation number from the collected variables. A total of 703 articles-211 published in Radiology, 48 in Investigative Radiology, 106 in AJNR, 52 in RadioGraphics, 129 in European Radiology, and 157 in AJR-were evaluated. Punctuation was included in the title in 55% of the articles and had the highest statistically significant positive correlation to citation rate (point-biserial correlation coefficient [r pb ] = 0.85, p < 0.05). Open access status provided a low-magnitude, but significant, correlation to citation rate (r pb = 0.140, p < 0.001). The following variables created a significant multiple regression model to predict citation count (p < 0.005, R 2 = 0.186): study findings in the title, abstract word count, abstract character count, total number of words, country of origin, and all authors in the field of radiology. Using bibliometric knowledge, authors can craft a title, abstract, and text that may enhance visibility and citation count over what they would otherwise experience.

Background The extent to which articles are cited is a surrogate of the impact and importance of the research conducted; poorly cited papers may identify research of limited use and potential wasted investments. We assessed trends in the rates of poorly cited articles and journals in the cardiovascular literature from 1997–2007. Methods and Results We identified original articles published in cardiovascular journals and indexed in the Scopus citation database from 1997–2007. We defined poorly cited articles as those with ≤5 citations in the 5 years following publication and poorly cited journals as those with >75% of journal content poorly cited. We identified 164,377 articles in 222 cardiovascular journals from 1997–2007. From 1997–2007, the number of cardiovascular articles and journals increased by 56.9% and 75.2% respectively. Of all the articles, 75,550 (46.0%) were poorly cited, of which 25,650 (15.6% overall) had no citations. From 1997–2007, the proportion of poorly cited articles declined slightly (52.1% to 46.2%, trend P<0.001), although the absolute number of poorly cited articles increased by 2,595 (trend P<0.001). At a journal level, 44% of cardiovascular journals had more than three quarters of the journal’s content poorly cited at 5 years. Conclusion Nearly half of all peer-reviewed articles published in cardiovascular journals are poorly cited 5 years after publication, and many are not cited at all. The cardiovascular literature, and the number of poorly cited articles, have both increased substantially from 1997–2007. The high proportion of poorly cited articles and journals suggest inefficiencies in the cardiovascular research enterprise. PMID:25812573

Articles by Latin American Authors in Prestigious Journals Have Fewer Citations

Background The journal Impact factor (IF) is generally accepted to be a good measurement of the relevance/quality of articles that a journal publishes. In spite of an, apparently, homogenous peer-review process for a given journal, we hypothesize that the country affiliation of authors from developing Latin American (LA) countries affects the IF of a journal detrimentally. Methodology/Principal Findings Seven prestigious international journals, one multidisciplinary journal and six serving specific branches of science, were examined in terms of their IF in the Web of Science. Two subsets of each journal were then selected to evaluate the influence of author's affiliation on the IF. They comprised contributions (i) with authorship from four Latin American (LA) countries (Argentina, Brazil, Chile and Mexico) and (ii) with authorship from five developed countries (England, France, Germany, Japan and USA). Both subsets were further subdivided into two groups: articles with authorship from one country only and collaborative articles with authorship from other countries. Articles from the five developed countries had IF close to the overall IF of the journals and the influence of collaboration on this value was minor. In the case of LA articles the effect of collaboration (virtually all with developed countries) was significant. The IFs for non-collaborative articles averaged 66% of the overall IF of the journals whereas the articles in collaboration raised the IFs to values close to the overall IF. Conclusion/Significance The study shows a significantly lower IF in the group of the subsets of non-collaborative LA articles and thus that country affiliation of authors from non-developed LA countries does affect the IF of a journal detrimentally. There are no data to indicate whether the lower IFs of LA articles were due to their inherent inferior quality/relevance or psycho-social trend towards under-citation of articles from these countries. However, further study is

2016-06-01

This article is aimed at providing evidence of increased international recognition of Clinics in Orthopedic Surgery (CiOS) based on journal metrics. Since 7 years have passed since its launch in 2009, it is time to reflect on the journal's efforts to be recognized as a top-notch journal. The following journal metrics were analyzed from the journal's homepage and Web of Science Core Collection database: number of citable and noncitable articles; number of original articles supported by grants; editorial board members' countries; authors' countries; citing authors' countries; source titles of citing articles; impact factor; total citations; comparison of impact factor with 3 Science Citation Index Expanded journals; and Hirsch index (H-index). Of the total 392 articles, 378 were citable articles (96.4%). Of the total 282 original articles, 52 (18.4%) were supported by research grants. The editorial board members were from 13 countries. Authors were from 20 countries. The number of countries of citing authors was 66. The number of source titles of citing articles was more than 100. The total citations of CiOS have increased from 0 in 2009 to 374 in 2015. The impact factors without self-citations of CiOS were the greatest among 4 Asian journals in 2013 and 2014. The 2015 impact factor was calculated as 0.79 in January 2016. The H-index was 13. CiOS can be considered to have reached the level of top-notch journal in the orthopedic field based on journal metrics. The inclusion of the journal in PubMed Central appears to have increased international relevance of the journal.

The number of citations that papers receive has become significant in measuring researchers' scientific productivity, and such measurements are important when one seeks career opportunities and research funding. Skewed citation practices can thus have profound effects on academic careers. We investigated (i) how frequently authors misinterpret original information and (ii) how frequently authors inappropriately cite reviews instead of the articles upon which the reviews are based. To reach this aim, we carried a survey of ecology journals indexed in the Web of Science and assessed the appropriateness of citations of review papers. Reviews were significantly more often cited than regular articles. In addition, 22% of citations were inaccurate, and another 15% unfairly gave credit to the review authors for other scientists' ideas. These practices should be stopped, mainly through more open discussion among mentors, researchers and students. PMID:24349143

The aim of this study was to evaluate the evolution of the citation of articles from the European Journal of Emergency Medicine (EJEM) from 1994 (EJEM foundation) to 2015 and identify highly cited articles and their principal characteristics and determine a possible correlation between the citations counted in different databases. We obtained the articles published in EJEM from 1994 to 2015 in ISI-WoS (main source) and Scopus, Google Scholar, and Medline databases (accessory sources). The citations were quantified and their annual evolution and the bibliometric indices derived (impact factor and SCImago Journal Rank) were evaluated. We identified and analyzed the highly cited EJEM articles and evaluated the possible correlation between the citations counted for these articles in the databases. Overall, 1705 EJEM articles were cited 9422 times in 8122 different articles. The evolution of the global citation, impact factor, and SCImago Journal Rank from 1994 to 2015 increased significantly. The h-index of EJEM was 30, and 31 articles were considered highly cited (≥30 citations), 16.1% of them being clinical trials. By subjects, 22.5% corresponded to cardiology, 19.3% to emergency department management, and 12.9% to pediatrics; by countries, 81% were from Europe, with Belgian authors publishing four (12.9%) highly cited articles, and French, Spanish, British, and Swedish authors having three (9.7%) each. Two studies in the EJEM achieved the definition of 'citation classics' (more than 100 citations). The number of citations in all the databases, except Medline, showed statistically significant correlations. Citation of EJEM articles has progressively increased and EJEM bibliometric indicators have improved; most highly cited articles are mainly by European authors.

Sewell, Joseph M.; Adejoro, Oluwakayode O.; Fleck, Joseph R.; Wolfson, Julian A.; Konety, Badrinath R.

2015-01-01

ABSTRACT Purpose: The Journal Impact Factor (JIF) is an index used to compare a journal's quality among academic journals and it is commonly used as a proxy for journal quality. We sought to examine the JIF in order to elucidate the main predictors of the index while generating awareness among scientific community regarding need to modify the index calculation in the attempt to turn it more accurate. Materials and Methods: Under the Urology and Nephrology category in the Journal Citations Report Website, the top 17 Journals by JIF in 2011 were chosen for the study. All manuscripts’ abstracts published from 2009-2010 were reviewed; each article was categorized based on its research design (Retrospective, Review, etc). T and correlation tests were performed for categorical and continuous variables respectively. The JIF was the dependent variable. All variables were then included in a multivariate model. Results: 23,012 articles from seventeen journals were evaluated with a median of 1,048 (range=78-6,342) articles per journal. Journals with a society affiliation were associated with a higher JIF (p=0.05). Self-citations (rho=0.57, p=0.02), citations for citable articles (rho=0.73, p=0.001), citations to non-citable articles (rho=0.65, p=0.0046), and retrospective studies (rho=-0.51, p=0.03) showed a strong correlation. Slight modifications to include the non-citable articles in the denominator yield drastic changes in the JIF and the ranking of the journals. Conclusion: The JIF appears to be closely associated with the number of citable articles published. A change in the formula for calculating JIF to include all types of published articles in the denominator would result in a more accurate representation. PMID:26742962

ABSTRACT Here, we describe the percentage of non-citation in Brazilian public health journals, a field that, until now, had not been investigated nationally or internationally. We analyzed articles, published between 2008 and 2012, of eight public health journals indexed in the scopus database. The percentage of non-citation differs between journals (from 5.7% to 58.1%). We identified four statistically distinct groups: História, Ciência, Saúde – Manguinhos (58% uncited articles); Physis: Revista de Saúde Coletiva, Interface, and Saúde e Sociedade (32% to 37%); Ciência & Saúde Coletiva and Revista Brasileira de Epidemiologia (16% to 17%); and Cadernos de Saúde Pública and Revista de Saúde Pública (6%). The non-citation in the first three years post-publication also varies according to journal. Four journals have shown a clear decline of non-citation: Cadernos de Saúde Pública, Ciência & Saúde Coletiva, Revista Brasileira de Epidemiologia, and Physis. Another three (Revista de Saúde Pública, Saúde e Sociedade, and Interface) presented an oscillation in non-citation, but the rates of 2008 and 2012 are similar, with different magnitudes. In turn, the journal História, Ciência, Saúde – Manguinhos maintains high rates of non-citation. Multidisciplinary journals attract more citation, but a comprehensive citation model still needs to be formulated and tested. PMID:29211202

The aim of this study was to use journal metrics to confirm that the Journal of Exercise Rehabilitation has been promoted to the international level after changing its language to English-only in April 2013. Journal metrics, including the number of articles per year, countries of authors, countries of the editorial board members, impact factor, total citations, and the Hirsch index, were counted or calculated based on the journal homepage and the Web of Science Core Collection in December 2016. The number of citable articles was 52, 62, 59, and 74 in 2013, 2014, 2015, and 2016, respectively. All authors were from Korea in 2013 and 2014, but the authors were from 11 countries in 2015 and from 16 countries in 2016. The editorial board members are currently from 11 countries. The impact factor without self-citations for 2015 was 0.912, corresponding to a Journal Citation Reports ranking of 32.9% out of 82 journals in the category of sport sciences. The total citations increased from 1 in 2013 to 130 in 2016. This journal was cited in 208 other source journals in the Web of Science. The citing authors were from 47 countries. The Hirsch index was 7, and review articles were the most frequently cited articles. The above results show a rapid development to the international level over 4 years. The introduction of digital technology to journals to improve their accessibility across multiple platforms is recommended.

Impact Factor (IF) as a major journal quality indicator has a series of shortcomings including effect of self-citation, review articles, total number of articles, etc. In this study, we compared 4 journals quality indices ((IF), Eigenfactor Score (ES), Article Influence Score (AIS) and SCImago Journal Rank indicator (SJR)) in the specific Pediatric Neurology journals. All ISI and Scopus indexed specific Pediatric Neurology journals were compared regarding their 2011 IF, ES, AIS and SJR. Fourteen pediatric Neurology journals were identified, 3 of which were only Scopus indexed and the others were both ISI and Scopus indexed. High correlation was found between IF and AIS (0.850). Correlations between IF and other indices were not that high. Self-citation, total article number and review articles were related to the IF and other indices as well as their ranks. English language and citation to non citable item didn't have any effect on pediatric neurology journals ranks. Although all the above mentioned indicators can be used interchangeably, using all considered indices is a more appropriate way than using only IF for quality assessment of pediatric neurology journals.

The impact factor and journals in laboratory medicine.

Lippi, Giuseppe; Favaloro, Emmanuel J; Guidi, Gian Cesare

2009-01-01

The impact factor, originally devised by Eugene Garfield, offsets the advantages of journal size and age, and is a tool often used for the evaluation of journals and scientists, and is considered to provide a reliable trend of basic and clinical research worldwide. Overall, the median impact factor of all medical laboratory journals increased by 23% from 2001 to 2007, but it was slightly decreased from that of the previous year (-4.1%). Moreover, the aggregate impact factor of all these journals, which takes into account the number of citations for all journals in this category and the number of articles from all journals in the same category, increased from 2.042 in 2003 to 2.153 in 2004, but decreased to 2.060 in 2005 and has remained fairly stable in subsequent years (2.054 in 2006 and 2.080 in 2007), reflecting remarkable increases and substantial reductions observed for individual journals. This trend mirrored that of biochemistry and molecular biology journals, whereas journals listed under the subject categories "pathology", "surgery" and "Medicine, general and internal" substantially increased their aggregate impact factor from 2003 to 2007. According to the impact factor trend of laboratory medicine journals, it appears that medical laboratory science has reached a steady state. This might be partially due to the radical changes that have occurred within medical laboratory science since the beginning of the last millennium and raises the question of whether laboratory professionals should consider embracing new areas of research, such as the role of laboratory diagnostics in surgery and internal medicine.

Differences in citation rates by country of origin for papers published in top-ranked medical journals: do they reflect inequalities in access to publication?

The acceptance of a paper in a top-ranked journal depends on the importance of the study, and should not depend on its country of origin. If the papers' citation rate is a proxy for their importance, and the threshold for acceptance is unrelated to the country of origin, papers from different countries published in the same journal should have a similar number of citations. Conversely, if the threshold is lowered for some countries, their papers will have a lower mean citation rate. The number of citations and the corresponding author's country were obtained for 4724 papers published between 1998 and 2002 in the British Medical Journal, the Lancet, Journal of the American Medical Association and New England Journal of Medicine. Countries were grouped according to the World Bank classification and geographical location: low-middle income countries; high-income European countries; high-income non-European countries; UK and USA. The probability of papers being poorly cited by country of origin was estimated, using domestic papers (British papers published in British journals and US papers published in US journals) as the reference. Compared with domestic papers, the OR of being poorly cited was 0.67 (95% CI 0.55 to 0.81) for papers from high-income European countries, 0.97 (0.76 to 1.24) for papers from high-income non-European countries and 1.93 (1.28 to 2.89) for papers from low-middle income countries. Papers from different countries published in the same journal have different citation rates. This may reflect difficulties for researchers from some countries to publish their research in leading medical journals.

2017-03-01

In December 2016, Elsevier launched a new tool that helps measure the citation impact of academic journals, called the CiteScore index. The CiteScore index values for 2015 confirmed the status of Acta Dermatovenerologica Alpina, Pannonica et Adriatica (Acta Dermatovenerol APA) as the leading journal in dermatology and sexually transmitted infections in the region. Sixty-five articles published in Acta Dermatovenerol APA from 2012 to 2014 received a total of 77 citations in 2015, resulting in a CiteScore index value of 1.18 for the journal. More than half of the articles published from 2012 to 2014 received at least one citation in 2015. Acta Dermatovenerol APA performed well in all three categories listed because it is ranked 384th out of 1,549 journals in the category General Medicine (75th percentile), 53rd out of 122 journals in the category Dermatology (56th percentile), and 142nd out of 246 journals in the category Infectious Diseases (42nd percentile).

Objectives A bibliometric analysis of the UK National Institute for Health Research (NIHR) Health Technology Assessment (HTA) monographs and their related journal articles by: (1) exploring the differences in citations to the HTA monographs in Google Scholar (GS), Scopus and Web of Science (WoS), and (2) comparing Scopus citations to the monographs with their related journal articles. Setting A study of 111 HTA monographs published in 2010 and 2011, and their external journal articles. Main outcome measures Citations to the monographs in GS, Scopus and WoS, and to their external journal articles in Scopus. Results The number of citations varied among the three databases, with GS having the highest and WoS the lowest; however, the citation-based rankings among the databases were highly correlated. Overall, 56% of monographs had a related publication, with the highest proportion for primary research (76%) and lowest for evidence syntheses (43%). There was a large variation in how the monographs were cited, compared to journal articles, resulting in more frequent problems, with unlinked citations in Scopus and WoS. When comparing differences in the number of citations between monograph publications with their related journal articles from the same project, we found that monographs received more citations than their journal articles for evidence syntheses and methodology projects; by contrast, journal articles related to primary research monographs were more highly cited than their monograph. Conclusions The numbers of citations to the HTA monographs differed considerably between the databases, but were highly correlated. When a HTA monograph had a journal article from the same study, there were more citations to the journal article for primary research, but more to the monographs for evidence syntheses. Citations to the related journal articles were more reliably recorded than citations to the HTA monographs. PMID:25694457

The reference sections from all articles in the 1997 volumes of Assessment, Journal of Personality Assessment, and Psychological Assessment were entered into a database and analyzed. An article published in Assessment averaged almost 31 references. An article published in Journal of Personality Assessment contained an average of 33 references. Psychological Assessment averaged 38 references per article. The median age of the references in the three journals was 8 years with an interquartile range of 4 to 14 years. The Journal of Personality Assessment had the largest number of citations in this database of 5,316 references. Each of these received a relatively large number of their citations from articles published in the same journal (self-citations). Randomly selected articles from the 1997 volume of Assessment received fewer citations in the Social Science Citation Index than a similar set of articles from the other two journals. However, the data on Assessment, when compared with data available on other new scientific publications, suggests that Assessment is doing as well as other fledgling journals.

How Far Has the International Neurourology Journal Progressed Since Its Transformation Into an English Language Journal?

2014-01-01

Purpose The publisher of the International Neurourology Journal changed the text to English in 2010 to promote the journal as an international publication. Four years later, what has happened to this journal? This paper will use citation indicators to describe the degree of internationalization. Methods Citation indicators such as impact factors, total citations from Web of Science, Science Journal Rankings (SJR), cites per documents (2 years), and Hirsch indexes (h-indexes) from Web of Science, digital object identifier (DOI)/CrossRef, ScimagoJR, or Scopus were calculated. In addition, the native countries of the authors and researchers citing the journal in Web of Science were analyzed. Results Impact factors in 2012 and 2013 were 0.645 and 0.857, respectively. Total citations in 2011, 2012, and 2013 from Web of Science were 15, 51, and 99, respectively, and the SJRs in 2011 and 2012 were 0.220 and 0.390, respectively. The h-indexes from DOI/CrossRef, Scopus, and Web of Science were 7, 8, and 6, respectively. Out of 153 unsolicited published papers, 27 (17.6%) were from outside of Korea. The researchers citing the journal in Web of Science and Scopus were primarily from the United States, Korea, China, the United Kingdom, and France. Funding agencies supported 39 of 101 original articles (38.6%). Conclusions After changing the text to the English language, the citation indicators show that the International Neurourology Journal has been elevated to an international journal. Although the nationality of authors varies from year to year, the increase in the number of manuscripts from international authors is obvious. PMID:24729921

Citations to articles published in academic journals represent a proxy for influence in bibliometrics. To measure the journal impact factor for Progress in Transplantation over time and to also identify related journals indexed in transplantation and surgery. Data from Journal Citation Reports (ISI web of science) were used to rank Progress in Transplantation compared to peer journals using journal impact and journal relatedness measures. Social network analysis was used to measure relationships between pairs of journals in Progress in Transplantation's relatedness network. Journal impact factor and journal relatedness. Data from 2010 through 2015 indicate the average journal article in PIT was cited 0.87 times (standard deviation [SD] = 0.12) and this estimate was stable over time. Progress in Transplantation most often cited American Journal of Transplantation, Transplantation, American Journal of Kidney Diseases, and Liver Transplantation. In terms of cited data, the journal was most often referenced by Clinical Transplantation, Transplant International, and Current Opinion in Organ Transplantation. The journal is listed both in surgery and transplantation categories of Journal Citation Reports and its impact factors over time fare better with surgery journals than with transplant journals. Network data using betweenness centrality indicate Progress in Transplantation links transplantation-focused journals and journals indexed in health sciences categories.

In this paper we present the first comprehensive bibliometric analysis of eleven open-access mega-journals (OAMJs). OAMJs are a relatively recent phenomenon, and have been characterised as having four key characteristics: large size; broad disciplinary scope; a Gold-OA business model; and a peer-review policy that seeks to determine only the scientific soundness of the research rather than evaluate the novelty or significance of the work. Our investigation focuses on four key modes of analysis: journal outputs (the number of articles published and changes in output over time); OAMJ author characteristics (nationalities and institutional affiliations); subject areas (the disciplinary scope of OAMJs, and variations in sub-disciplinary output); and citation profiles (the citation distributions of each OAMJ, and the impact of citing journals). We found that while the total output of the eleven mega-journals grew by 14.9% between 2014 and 2015, this growth is largely attributable to the increased output of Scientific Reports and Medicine. We also found substantial variation in the geographical distribution of authors. Several journals have a relatively high proportion of Chinese authors, and we suggest this may be linked to these journals' high Journal Impact Factors (JIFs). The mega-journals were also found to vary in subject scope, with several journals publishing disproportionately high numbers of articles in certain sub-disciplines. Our citation analsysis offers support for Björk & Catani's suggestion that OAMJs's citation distributions can be similar to those of traditional journals, while noting considerable variation in citation rates across the eleven titles. We conclude that while the OAMJ term is useful as a means of grouping journals which share a set of key characteristics, there is no such thing as a "typical" mega-journal, and we suggest several areas for additional research that might help us better understand the current and future role of OAMJs in

Bibliometrics are a set of methods, which can be used to analyze academic literature quantitatively and its changes over time. The objectives of this study were 1) to evaluate trends related to academic performance of dental journals from 2003 to 2012 using bibliometric indices, and 2) monitor the changes of the five dental journals with the highest and lowest impact factor (IF) published in 2003. Data for the subject category "Dentistry, Oral Surgery & Medicine" was retrieved from the Journal Citation Reports (JCR) published from 2003 to 2012. Linear regressions analysis was used to determine statistical trends over the years with each bibliometric indicator as the dependent variable and the JCR year as the predictor variable. Statistically significant rise in the total number of dental journals, the number of all articles with the steepest rise observed for research articles, the number of citations and the aggregate IF was observed from 2003 to 2012. The analysis of the five top and five bottom-tire dental journals revealed a rise in IF however, with a wide variation in relation to the magnitude of this rise. Although the IF of the top five journals remained relatively constant, the percentile ranks of the four lowest ranking journals in 2003 increased significantly with the sharpest rise being noted for the British Journal of Oral & Maxillofacial Surgery. This study revealed significant growth of dental literature in absolute terms, as well as upward trends for most of the citation-based bibliometric indices from 2003 to 2012. PMID:25781486

Citation analysis was used to analyze the references cited in 1825 articles published in CJIM from 2001 to 2004 according to their time sequence of publishing. The citation rate was 53.64%, and 9.51% citations per article. Most of the citations were mainly cited from journals (85.38%) and books (13.4%). The Price Index was 49.22%, and the self-citation rate for author and periodical were 3.63% and 7.77% respectively. CJITWM is a highly authorized and representative professional academic periodical in the field of ICWM. The citations are mainly cited from periodicals written in Chinese or English, they are of good novelty and quality, but the citation rate should be further improved.

To analyze the inherent quality of articles published in our journal enjoying high citation rate, and to explore strategies on improving impact of papers. Scientific papers published in Chinese Journal of Burns from February 2000 to December 2009, with citation rate equal to or higher than 20 times were collected for classification according to their publication year, publication form, subject distribution, regional and institutional distribution, frequency of authors appeared in those published papers, frequency of winning prizes, and sources of fund (national, ministerial, or provincial). Data were processed by Microsoft Excel software. Altogether 64 scientific papers with high citation rate were published from 2000 to 2006. Original articles and expert forum accounted for 55 (86.0%). Twenty-one articles of clinical study were cited frequently, among them one was cited for 79 times. Articles dealing with subjects with popular interest or cutting-edge problems were cited frequently. Most articles winning high citation rate were originated from institutions located in Chongqing, Beijing, Shanghai, and Xi'an, etc. Those scientific papers which were instructed by specialists, with high level foundation and won prizes were cited with high frequency. The top 20 articles were mainly cited by excellent doctoral dissertations and master theses originated from 11 institutions for higher education, and source journals of Chinese Scientific and Technical Papers and Citations Database. Authors should emphasize subject planning in order to compose papers with high quality. The editorial board should make arrangements with influential specialists with related skills for their contributions based on subjects of popular interest concerning the cutting-edge problems of the specific specialty, and pay close attention to papers on clinical study and those with funding from high levels, to improve impact of the articles.

2018-01-01

Journal peer review lies at the heart of academic quality control. This article explores the journal peer review process and seeks to examine how the reviewing process might itself contribute to papers, leading them to be more highly cited and to achieve greater recognition. Our work builds on previous observations and views expressed in the literature about (a) the role of actors involved in the research and publication process that suggest that peer review is inherent in the research process and (b) on the contribution reviewers themselves might make to the content and increased citation of papers. Using data from the journal peer review process of a single journal in the Social Sciences field (Business, Management and Accounting), we examine the effects of peer review on papers submitted to that journal including the effect upon citation, a novel step in the study of the outcome of peer review. Our detailed analysis suggests, contrary to initial assumptions, that it is not the time taken to revise papers but the actual number of revisions that leads to greater recognition for papers in terms of citation impact. Our study provides evidence, albeit limited to the case of a single journal, that the peer review process may constitute a form of knowledge production and is not the simple correction of errors contained in submitted papers.

[Citation rates of medical German-language journals in English-language papers - do they correlate with the Impact Factor, and who cites?].

PubMed

Winkmann, G; Schlutius, S; Schweim, H G

2002-01-25

Several publications are warning that the German language is no longer needed for transmission of scientific data. One of the causes may be the Impact Factor (IF), which appears to be derived predominantly from Anglo-American journals. The aim of this study was to check actual international attention paid to German-language journals, i. e. their citation frequencies in English-language papers. Are these citing rates in English-language articles correlated to the IF, and from where do citing articles originate? Of 25 arbitrarily selected >85 % German-language medical journals, IF as well as language distributions of citing articles were determined by searching publication years 1995 - 2000 in Science Citation Index (SCI). MEDLINE and EMBASE were used as supplementary retrieval systems. (i) The sample journals displayed an average IF = 0.357. A 99 % correlation (Pearson factor r = 0.987; n = 25) was observed between our > constructed< IF 2000 and IF published in Journal Citation Report 2000. This proves Stegmann's IF determination method to be valid. On the average, 53 % German-language and 45 % English-language articles between 1995 - 2000 cited the 1995 - 1999' contributions of the studied journals. No correlation was observed between IF vs. rates of citing articles in English (r <0.1). 64 % of citing English-language articles showed corporate sources in Germany/ Austria/ Switzerland, and 13.5 % authors' institutions in USA. (i) An IF >/=1 is, obviously, very hard to attain by German-language journals. ISI's differentiation between Citing vs. Cited-only Journals (the latter often serving as MEDLINE/ EMBASE sources) during derivation of IF appears unjustified. (ii) English now serves as the predominant communication language in sciences in German-speaking countries, but has not supplanted the German language. Our study reveals remarkable international attention rates remaining.

Until recently, Web of Science was the only database available to track citation counts for published articles. Other databases are now available, but their relative performance has not been established. To compare the citation count profiles of articles published in general medical journals among the citation databases of Web of Science, Scopus, and Google Scholar. Cohort study of 328 articles published in JAMA, Lancet, or the New England Journal of Medicine between October 1, 1999, and March 31, 2000. Total citation counts for each article up to June 2008 were retrieved from Web of Science, Scopus, and Google Scholar. Article characteristics were analyzed in linear regression models to determine interaction with the databases. Number of citations received by an article since publication and article characteristics associated with citation in databases. Google Scholar and Scopus retrieved more citations per article with a median of 160 (interquartile range [IQR], 83 to 324) and 149 (IQR, 78 to 289), respectively, than Web of Science (median, 122; IQR, 66 to 241) (P < .001 for both comparisons). Compared with Web of Science, Scopus retrieved more citations from non-English-language sources (median, 10.2% vs 4.1%) and reviews (30.8% vs 18.2%), and fewer citations from articles (57.2% vs 70.5%), editorials (2.1% vs 5.9%), and letters (0.8% vs 2.6%) (all P < .001). On a log(10)-transformed scale, fewer citations were found in Google Scholar to articles with declared industry funding (nonstandardized regression coefficient, -0.09; 95% confidence interval [CI], -0.15 to -0.03), reporting a study of a drug or medical device (-0.05; 95% CI, -0.11 to 0.01), or with group authorship (-0.29; 95% CI, -0.35 to -0.23). In multivariable analysis, group authorship was the only characteristic that differed among the databases; Google Scholar had significantly fewer citations to group-authored articles (-0.30; 95% CI, -0.36 to -0.23) compared with Web of Science.

Journal impact factors are a metric often used to evaluate journals; they are calculated by considering a journal's citation and publication rates during a specified time period. In some cases, impact factors can be misleading because they do not take into account the publication of different types of papers. In the "Journal of Chemical…

Purpose The total number of times a paper is cited, also known as the impact factor (IF) of a medical journal, is widely implied in evaluating the quality of a research paper. We evaluated the citation index data as an IF of Korean J Pediatr in Korean Medical Citation Index (KoMCI) and JCI of Web of Science. Methods We calculated the IF of Korean J Pediatr at KoMCI supervised by Korean Association of Medical Journal Editors. And we estimated the IF of Korean J Pediatr by the JCI of Web of Science although it was never officially reported. Results The IF of Korean J Pediatr on KoMCI has increased from 0.100 in the year 2000, to 0.205 in 2008, and 0.326 in 2009. Although the IF of Korean J Pediatr was 0.006 in 2005, 0.018 in 2006, 0.028 in 2008, 0.066 in 2009, and 0.018 in 2010 according to the JCI of Web of Science, the number of citations are steadily increasing. Conclusion Understanding and realizing the current status will be a stepping stone for further improvement. The next objective of the Korean J Pediatr is to become registered in the SCI or SCIE. Increasing the IF according to the JCI of Web of Science is crucial in order to achieve this goal. PMID:21738548

[Citation rates of medical German-language journals in English-language papers--do they correlate with the impact factor, and who cites? (reprint)].

PubMed

Winkmann, G; Schlutius, S; Schweim, H G

2002-01-01

Several publications are warning that the German language is no longer needed for transmission of scientific data. One of the causes may be the Impact Factor (IF), which appears to be derived predominantly from Anglo-American journals. The aim of this study was to check actual international attention paid to German-language journals, i. e. their citation frequencies in English-language papers. Are these citing rates in English-language articles correlated to the IF, and from where do citing articles originate? Of 25 arbitrarily selected > 85 % German-language medical journals, IF as well as language distributions of citing articles were determined by searching publication years 1995 - 2000 in Science Citation Index (SCI). MEDLINE and EMBASE were used as supplementary retrieval systems. (i) The sample journals displayed an average IF = 0.357. A 99 % correlation (Pearson factor r = 0.987; n = 25) was observed between our "constructed" IF 2000 and IF published in Journal Citation Report 2000. This proves Stegmann's IF determination method to be valid. On the average, 53 % German-language and 45 % English-language articles between 1995 - 2000 cited the 1995 - 1999' contributions of the studied journals. No correlation was observed between IF vs. rates of citing articles in English (r < 0.1). 64 % of citing English-language articles showed corporate sources in Germany/Austria/Switzerland, and 13.5 % authors' institutions in USA. (i) An IF >/= 1 is, obviously, very hard to attain by German-language journals. ISI's differentiation between Citing vs. Cited-only Journals (the latter often serving as MEDLINE/EMBASE sources) during derivation of IF appears unjustified. (ii) English now serves as the predominant communication language in sciences in German-speaking countries, but has not supplanted the German language. Our study reveals remarkable international attention rates remaining.

To compare clinical trials published in Brazilian journals of ophthalmology and in foreign journals of ophthalmology with respect to the number of citations and the quality of reporting [by applying the Consolidated Standards for Reporting Trials (CONSORT) statement writing standards]. The sample of this systematic review comprised the two Brazilian journals of ophthalmology indexed at Science Citation Index Expanded and six of the foreign journals of ophthalmology with highest Impact Factor® according ISI. All clinical trials (CTs) published from January 2009 to December 2010 at the Brazilians journals and a 1:1 randomized sample of the foreign journals were included. The primary outcome was the number of citations through the end of 2011. Subgroup analysis included language. The secondary outcome included likelihood of citation (cited at least once versus no citation), and presence or absence of CONSORT statement indicators. The citation counts were statistically significantly higher (P<0.001) in the Foreign Group (10.50) compared with the Brazilian Group (0.45). The likelihood citation was statistically significantly higher (P<0.001) in the Foreign Group (20/20 - 100%) compared with the Brazilian Group (8/20 - 40%). The subgroup analysis of the language influence in Brazilian articles showed that the citation counts were statistically significantly higher in the papers published in English (P<0.04). Of 37 possible CONSORT items, the mean for the Foreign Group was 20.55 and for the Brazilian Group was 13.65 (P<0.003). The number of citations and the quality of reporting of clinical trials in Brazilian journals of ophthalmology still are low when compared with the foreign journals of ophthalmology with highest Impact Factor®.

The ethics of peer and editorial requests for self-citation of their work and journal.

PubMed

Teixeira da Silva, Jaime A

2017-04-01

Peer reviewers are expected to be experts in a field of study and should be versed with the pertinent literature related with the manuscript they are reviewing. Editors might not necessarily be experts in a particular field, but they have the responsibility of overseeing the requests made by peers, and assessing whether these are ethically appropriate, or not. Thus, requests by peers to cite unrelated literature, which may or may not be their own literature, could be unethical, especially if the objective is to improve their own citations or to boost the citations of the journal for which they are reviewing. In contrast, requests to cite pertinent work that is in fact missing from the paper's literature, even if it may be the reviewer or editor's work, or from the same journal, is acceptable. Editors ultimately approve the requests and suggestions made by reviewers, so inappropriate suggestions made by peer reviewers are the responsibility of the editor and journal. There needs to be a bias-free mechanism in place that offers protection to authors who wish to complain, and consequences for editors who do not conduct an impartial decision. Authors have the right to challenge such suggestions, but may face unfair retaliation in the form of a rejection if they resist making changes that they perceive as being inappropriate.

The article overviews some achievements and problems of Korean medical journals published in the highly competitive journal environment. Activities of Korean Association of Medical Journal Editors (KAMJE) are viewed as instrumental for improving the quality of Korean articles, indexing large number of local journals in prestigious bibliographic databases and launching new abstract and citation tracking databases or platforms (eg KoreaMed, KoreaMed Synapse, the Western Pacific Regional Index Medicus [WPRIM]). KAMJE encourages its member journals to upgrade science editing standards and to legitimately increase citation rates, primarily by publishing more great articles with global influence. Experience gained by KAMJE and problems faced by Korean editors may have global implications.

The Korean Journal of Internal Medicine has already been valued as an international journal, according to a citation analysis in 2011. Now, 2 years later, I would like to confirm how much the Journal has advanced from the point of view of journal metrics by looking at the impact factor, cites per document (2 years), SCImago Journal Rank (SJR), and the Hirsch index. These were obtained from a variety of databases, such as the Korean Medical Citation Index, KoreaMed Synapse, Web of Science, JCR Web, and SCImago Journal & Country Rank. The manually calculated 2012 impact factor was 1.252 in the Web of Science, with a ranking of 70/151 (46.4%) in the category of general and internal medicine. Cites per documents (2 years) for 2012 was 1.619, with a ranking of 267/1,588 (16.8%) in the category of medicine (miscellaneous). The 2012 SJR was 0.464, with a ranking of 348/1,588 (21.9%) in the category of medicine (miscellaneous). The Hirsch index from KoreaMed Synapse, Web of Science, and SCImago Journal & Country Rank were 12, 15, and 19, respectively. In comparison with data from 2010, the values of all the journal metrics increased consistently.

Background Internal medicine includes several subspecialties. This study aimed to describe change trend of impact factors in different subspecialties of internal medicine during the past 12 years, as well as the developmental differences among each subspecialty, and the possible influencing factors behind these changes and differences. Methods Nine subspecialties of internal medicine were chosen for comparison. All data were collected from the Science Citation Index Expanded and Journal Citation Reports database. Results (1) Journal numbers in nine subspecialties increased significantly from 1998 to 2010, with an average increment of 80.23%, in which cardiac and cardiovascular system diseases increased 131.2% rank the first; hematology increased 45% rank the least. (2) Impact Factor in subspecialties of infectious disease, cardiac and cardiovascular system diseases, gastroenterology and hepatology, hematology, endocrinology and metabolism increased significantly (p<0.05), in which gastroenterology and hepatology had the largest increase of 65.4%. (3) Journal impact factor of 0–2 had the largest proportion in all subspecialties. Among the journals with high impact factor (IF>6), hematology had the maximum proportion of 10%, nephrology and respiratory system disease had the minimum of 4%. Among the journal with low impact factor (IF<2), journal in nephrology and allergy had the most (60%), while endocrinology and metabolism had the least (40%). There were differences in median number of IF among the different subspecialties (p<0.05), in which endocrinology and metabolism had the highest, nephrology had the lowest. (4) The highest IF had a correlation with journal numbers and total paper numbers in each field. Conclusion The IF of internal medicine journals showed an increasingly positive trend, in which gastroenterology and hepatology increase the most. Hematology had more high IF journals. Endocrinology and metabolism had higher average IF. Nephrology remained the

In the past few years there has been an ongoing debate as to whether the proliferation of open access (OA) publishing would damage the peer review system and put the quality of scientific journal publishing at risk. Our aim was to inform this debate by comparing the scientific impact of OA journals with subscription journals, controlling for journal age, the country of the publisher, discipline and (for OA publishers) their business model. The 2-year impact factors (the average number of citations to the articles in a journal) were used as a proxy for scientific impact. The Directory of Open Access Journals (DOAJ) was used to identify OA journals as well as their business model. Journal age and discipline were obtained from the Ulrich's periodicals directory. Comparisons were performed on the journal level as well as on the article level where the results were weighted by the number of articles published in a journal. A total of 610 OA journals were compared with 7,609 subscription journals using Web of Science citation data while an overlapping set of 1,327 OA journals were compared with 11,124 subscription journals using Scopus data. Overall, average citation rates, both unweighted and weighted for the number of articles per journal, were about 30% higher for subscription journals. However, after controlling for discipline (medicine and health versus other), age of the journal (three time periods) and the location of the publisher (four largest publishing countries versus other countries) the differences largely disappeared in most subcategories except for journals that had been launched prior to 1996. OA journals that fund publishing with article processing charges (APCs) are on average cited more than other OA journals. In medicine and health, OA journals founded in the last 10 years are receiving about as many citations as subscription journals launched during the same period. Our results indicate that OA journals indexed in Web of Science and/or Scopus are

Retracted Publications Within Radiology Journals.

PubMed

Rosenkrantz, Andrew B

2016-02-01

The purpose of this study was to characterize trends related to retracted publications within radiology journals. PubMed was queried to identify all articles with the publication type "retracted publication" or "notification of retraction." Articles published within radiology journals were identified using Journal Citation Reports' journal categories. Available versions of original articles and publication notices were accessed from journal websites. Citations to retracted publications were identified using Web of Science. Overall trends were assessed. Forty-eight retracted original research articles were identified within radiology journals since 1983, which included 1.1% of all PubMed "retracted publication" entries. Distinct PubMed entries were available for the retracted publication and retraction notification in 39 of 48 articles. The original PDF was available for 37 articles, although the articles were not watermarked as retracted in 23 cases. In six cases with a watermarked PDF, further searches identified nonwatermarked versions. Original HTML versions were available for 13 articles but 11 were not watermarked. The mean (± SD) delay between publication and retraction was 2.7 ± 2.8 years (range, 0-16 years). The mean number of citations to retracted articles was 10.9 ± 17.1 (range, 0-94 citations). Reasons for retraction included problematic or incorrect methods or results (although it typically was unclear whether these represented honest errors or misconduct) in 33.3% of cases, complete or partial duplicate publication in 33.3% of cases, plagiarism in 14.6% of cases, a permission issue in 8.3% of cases, the publisher's error in 6.3% of cases, and no identified reason in 6.3% of cases. One or no retractions occurred annually from 1986 to 2001, although two or more retractions occurred annually in nine of the 12 years from 2002 through 2013. Retraction represents an uncommon, yet potentially increasing, issue within radiology journals that publishers

Open access to journal articles in dentistry: Prevalence and citation impact.

To investigate the current prevalence of open access (OA) in the field of dentistry, the means used to provide OA, as well as the association between OA and citation counts. PubMed was searched for dental articles published in 2013. The OA status of each article was determined by manually checking Google, Google Scholar, PubMed and ResearchGate. Citation data were extracted from Google Scholar, Scopus and Web of Science. Chi-square tests were used to compare the OA prevalence by different subjects, study types, and continents of origin. The association between OA and citation count was studied with multivariable logistic regression analyses. A random sample of 908 articles was deemed eligible and therefore included. Among these, 416 were found freely available online, indicating an overall OA rate of 45.8%. Significant difference in OA rate was detected among articles in different subjects (P<0.001) and among those from different continents (P<0.001). Of articles that were OA, 74.2% were available via self-archiving ('Green road' OA), 53.3% were available from publishers ('Gold road' OA). According to multivariable logistic regression analyses, OA status was not significantly associated with either the existence of citation (P=0.37) or the level of citation (P=0.52). In the field of dentistry, 54% of recent journal articles are behind the paywall (non-OA) one year after their publication dates. The 'Green road' of providing OA was more common than the 'Gold road'. No evidence suggested that OA articles received significantly more citations than non-OA articles.

2018-02-01

The open access movement has pushed for greater access to scientific knowledge by expanding access to scientific journal articles. There is limited information about the extent to which open access policies have been adopted by radiology journals. We performed a systematic analysis to ascertain the proportion of radiology journals with open access options. A search was performed with the assistance of a clinical informationist. Full and mixed English-language diagnostic and interventional radiology Web of Science journals (impact factors > 1.0) were included. Nuclear medicine, radiation oncology, physics, and solicitation-only journals were excluded. Primary outcome was open access option (yes or no) with additional outcomes including presence or absence of embargo, complete or partial copyright transfer, publication fees, and self-archiving policies. Secondary outcomes included journal citations, journal impact factors, immediacy, Eigenfactor, and article influence scores. Independent double readings were performed with differences resolved by consensus, supplemented by contacting editorial staff at each journal. In all, 125 journals were identified; review yielded 49 journals (39%, mean impact factor of 2.61). Thirty-six of the journals had open access options (73.4%), and four journals were exclusively open access (8.2%). Twelve-month embargoes were most commonly cited (90.6%) with 28.6% of journals stating that they did not require a complete transfer of copyright. Prices for open access options ranged from $750 to $4,000 (median $3,000). No statistically significant differences were found in journal impact measures comparing journals with open access options to journals without open access options. Diagnostic and interventional radiology journals have widely adopted open access options with a few radiology journals being exclusively open access. Copyright © 2017 American College of Radiology.

Impact Factors Show Increased Use of AGU Journals in 2008

NASA Astrophysics Data System (ADS)

Ford, Barbara Meyers

2009-07-01

The latest numbers released from Journal Citation Reports (JCR), published annually by Thomson Reuters, show large increases in the impact factor (IF) for several AGU journals. IFs are one way for publishers to know that readers have found their journals useful and of value in research. A journal's IF is calculated by taking the total number of citations to articles published by a given journal in the past 2 years and dividing it by the total number of papers published by the journal in the same time period. More generally, it can be seen as the frequency with which articles in a journal have been cited over the past year. The numbers speak for themselves (see Table 1).

Concentration of the Most-Cited Papers in the Scientific Literature: Analysis of Journal Ecosystems

PubMed Central

Ioannidis, John P. A.

2006-01-01

Background A minority of scientific journals publishes the majority of scientific papers and receives the majority of citations. The extent of concentration of the most influential articles is less well known. Methods/Principal Findings The 100 most-cited papers in the last decade in each of 21 scientific fields were analyzed; fields were considered as ecosystems and their “species” (journal) diversity was evaluated. Only 9% of journals in Journal Citation Reports had published at least one such paper. Among this 9%, half of them had published only one such paper. The number of journals that had published a larger number of most-cited papers decreased exponentially according to a Lotka law. Except for three scientific fields, six journals accounted for 53 to 94 of the 100 most-cited papers in their field. With increasing average number of citations per paper (citation density) in a scientific field, concentration of the most-cited papers in a few journals became even more prominent (p<0.001). Concentration was unrelated to the number of papers published or number of journals available in a scientific field. Multidisciplinary journals accounted for 24% of all most-cited papers, with large variability across fields. The concentration of most-cited papers in multidisciplinary journals was most prominent in fields with high citation density (correlation coefficient 0.70, p<0.001). Multidisciplinary journals had published fewer than eight of the 100 most-cited papers in eight scientific fields (none in two fields). Journals concentrating most-cited original articles often differed from those concentrating most-cited reviews. The concentration of the most-influential papers was stronger than the already prominent concentration of papers published and citations received. Conclusions Despite a plethora of available journals, the most influential papers are extremely concentrated in few journals, especially in fields with high citation density. Existing

The 2001 edition of the Journal Citation Reports (JCR) includes only 13 Spanish medical journals. The impact factor (IF) of the rest of Spanish medical journals is unknown. The aim of this study is to determine the IF of the main Spanish medical journals, taking also into account the references from journals not covered by the SCI. A set of 87 Spanish medical journals was selected from the national database IME and other international databases. All citable articles published in these journals in 2001 were analyzed, extracting their bibliographic references to articles published in 1999, 2000 and 2001. The indicators obtained for each journal were the number of cites, the IF and the immediacy index. Among the 87 source journals, 74 were not included in the JCR. From them, 5,388 bibliographic references were examined, identifying the journals cited. Final indicators were obtained adding these results to the ones obtained by using the Science Citation Index. The most cited journal was Medicina Clinica (768 cites), and the highest IF were attained by Histology and Histopathology (IF = 1.866), International Journal of Developmental Biology (IF = 1.654) and Medicina Clinica (IF = 1.125). This work has permitted to obtain the IF of 87 Spanish medical journals. Already detected in previous works, the leadership of the journal Medicina Clinica in Spanish medicine is confirmed. Spanish medical journals published in English have received a small number of cites from the ones published in Spanish. A low impact factor is not necessarily related to lack of quality, merit or relevance.

Publication in a Brazilian journal by Brazilian scientists whose papers have international impact.

Meneghini, R

2010-09-01

Nine Brazilian scientists with an outstanding profile of international publications were invited to publish an original article in the same issue of a Brazilian Journal (Anais da Academia Brasileira de Ciências). The objective was to measure the impact of the papers on the number of citations to the articles, the assumption being that these authors would carry their international prestige to the Brazilian periodical. In a 2-year period there was a larger number of citations of these articles compared to others published in the same journal. Nevertheless, the number of citations in Brazilian journals did not equal the number of citations obtained by the other papers by the same authors in their international publications within the same 2-year period. The reasons for this difference in the number of citations could be either that less significant invited articles were submitted or that it was due to the intrinsic lack of visibility of the Brazilian journals, but this could not be fully determined with the present data. Also relevant was a comparison between the citations of Brazilian journals and the publication in Brazilian journals by these selected authors. A clear imbalance due to a remarkable under-citation of Brazilian authors by authors publishing in Brazilian journals raises the possibility that psychological factors may affect the decision of citing Brazilian journals.

Publishing articles in a prestigious journal is a golden rule for university professors and researchers nowadays. Impact factor, journal rank, and citation count, included in Science Citation Index managed by Thomson Reuters Web of Science, are the most important indicators for evaluating the quality of academic journals. By listing the journals encompassed in the “Integrative and Complementary Medicine” category of Science Citation Index from 2003 to 2013, this paper examines the publication trends of journals in the category. The examination includes number, country of origin, ranking, and languages of journals. Moreover, newly listed or removed journals in the category, journal publishers, and open access strategies are examined. It is concluded that the role of journal publisher should not be undermined in the “Integrative and Complementary Medicine” category. PMID:26213508

We analyze a database comprising the impact factor (citations per recent items published) of scientific journals for a 13-year period (1992 2004). We find that i) the distribution of impact factors follows asymptotic power law behavior, ii) the distribution of annual logarithmic growth rates has an exponential form, and iii) the width of this distribution decays with the impact factor as a power law with exponent β simeq 0.22. The results ii) and iii) are surprising similar to those observed in the growth dynamics of organizations with complex internal structure suggesting the existence of common mechanisms underlying the dynamics of these systems. We propose a general model for such systems, an extension of the simplest model for firm growth, and compare their predictions with our empirical results.

To identify and analyse the 100 most cited papers on stress in nurses published in nursing journals. The number of citations an article receives is an index of its impact on the scientific community. An analysis of the most cited articles on stress in nursing would allow us to identify the most important articles and to obtain information about this area of knowledge. A retrospective bibliometric analysis. In 2016, 111 journals belonging to the "nursing" category were identified in the Science and Social Science Citation Index. A search was performed of the Science Core Collection Website for articles on stress published in these journals. The topic, type of article, publishing journal, countries and institutions of origin and year of publication were extracted from the articles. The impact factor, immediacy index, journal country and publisher and h index were collected from the Institute for Scientific Information. The citation density, citation tendency and Bradford's law were calculated. They identified articles were mostly empirical quantitative studies with a transversal design, published from 1975 - 2011 in 23 journals. They were signed by 233 authors, most of whom are English-speaking from the USA and UK. The core distribution of the publications comprises a single journal, the Journal of Advanced Nursing. The study of stress in nursing has shown increased visibility and recognition each decade. The most recent articles have the highest number of citations, are the highest in rank and have the higher citation densities. © 2018 John Wiley & Sons Ltd.

Medical journals, impact and social media: an ecological study of the Twittersphere.

Twitter is an increasingly popular means of research dissemination. I sought to examine the relation between scientific merit and mainstream popularity of general medical journals. I extracted impact factors and citations for 2014 for all general medical journals listed in the Thomson Reuters InCites Journal Citation Reports. I collected Twitter statistics (number of followers, number following, number of tweets) between July 25 and 27, 2015 from the Twitter profiles of journals that had Twitter accounts. I calculated the ratio of observed to expected Twitter followers according to citations via the Kardashian Index. I created the (Fifty Shades of) Grey Scale to calculate the analogous ratio according to impact factor. Only 28% (43/153) of journals had Twitter profiles. The scientific and social media impact of journals were correlated: in adjusted models, Twitter followers increased by 0.78% (95% confidence interval [CI] 0.38%-1.18%) for every 1% increase in impact factor and by 0.62% (95% CI 0.34%-0.90%) for every 1% increase in citations. Kardashian Index scores above the 99% CI were obsverved in 16% (7/43) of journals, including 6 of the 7 highest ranked journals by impact factor, whereas 58% (25/43) had scores below this interval. For the Grey Scale, 12% (5/43) of journals had scores above and 35% (15/43) had scores below the 99% CI. The size of a general medical journal's Twitter following is strongly linked to its impact factor and citations, suggesting that higher quality research received more mainstream attention. Many journals have not capitalized on this dissemination method, although others have used it to their advantage. © 2015 Canadian Medical Association or its licensors.

The Journal of Psychology: Interdisciplinary and Applied is a leading international journal in psychology dating back to 1935. This study examines its publications since its creation utilizing a bibliometric analysis. The primary objective is to provide a complete overview of the key factors affecting the journal. This analysis includes such key issues as the publication and citation structure of the journal, its most cited articles, and the leading authors, institutions, and countries referenced in the journal. The work uses the Scopus database to classify the bibliographic material. Additionally, the analysis provides a graphical mapping of the bibliographic data by using visualization of similarities viewer software. This software uses several bibliometric techniques including co-citation, bibliographic coupling and co-occurrence of keywords. The Journal of Psychology is strongly connected to most of the current leading journals in psychology, and currently has a 5-year impact factor of 1.77 (Thomson Reuters, 2015 Journal Citation Reports).

Many biomedical publications refer to data obtained from collections of biosamples. Sharing such bioresources (biological samples, data, and databases) is paramount for the present governance of research. Recognition of the effort involved in generating, maintaining, and sharing high quality bioresources is poorly organized, which does not encourage sharing. At publication level, the recognition of such resources is often neglected and/or highly heterogeneous. This is a true handicap for the traceability of bioresource use. The aim of this article is to propose, for the first time, a guideline for reporting bioresource use in research articles, named CoBRA: Citation of BioResources in journal Articles. As standards for citing bioresources are still lacking, the members of the journal editors subgroup of the Bioresource Research Impact Factor (BRIF) initiative developed a standardized and appropriate citation scheme for such resources by informing stakeholders about the subject and raising awareness among scientists and in science editors' networks, mapping this topic among other relevant initiatives, promoting actions addressed to stakeholders, launching surveys, and organizing focused workshops. The European Association of Science Editors has adopted BRIF's suggestion to incorporate statements on biobanks in the Methods section of their guidelines. The BRIF subgroup agreed upon a proposed citation system: each individual bioresource that is used to perform a study and that is mentioned in the Methods section should be cited as an individual "reference [BIORESOURCE]" according to a delineated format. The EQUATOR (Enhancing the QUAlity and Transparency Of health Research) network mentioned the proposed reporting guideline in their "guidelines under development" section. Evaluating bioresources' use and impact requires that publications accurately cite such resources. Adopting the standard citation scheme described here will improve the quality of bioresource

Do review articles boost journal impact factors? A longitudinal analysis for five pharmacology journals.

The impact factor is a frequently applied tool in research output analytics. Based on five consecutive publication years each of five pharmacology journals, we have analyzed to which extent review articles yield more impact factor-relevant citations than original articles. Our analysis shows that review articles are quoted about twice as often as original articles published in the same year in the same journal. We conclude that inclusion of review articles does not substantially affect the impact factor of a journal unless they account for considerably more than 10% of all published articles.

Citation metrics and h indices differ using different bibliometric databases. We compiled the number of publications, number of citations, h index and year since the first publication from 340 soil researchers from all over the world. On average, Google Scholar has the highest h index, number of publications and citations per researcher, and the Web of Science the lowest. The number of papers in Google Scholar is on average 2.3 times higher and the number of citations is 1.9 times higher compared to the data in the Web of Science. Scopus metrics are slightly higher than that of the Web of Science. The h index in Google Scholar is on average 1.4 times larger than Web of Science, and the h index in Scopus is on average 1.1 times larger than Web of Science. Over time, the metrics increase in all three databases but fastest in Google Scholar. The h index of an individual soil scientist is about 0.7 times the number of years since his/her first publication. There is a large difference between the number of citations, number of publications and the h index using the three databases. From this analysis it can be concluded that the choice of the database affects widely-used citation and evaluation metrics but that bibliometric transfer functions exist to relate the metrics from these three databases. We also investigated the relationship between journal's impact factor and Google Scholar's h5-index. The h5-index is a better measure of a journal's citation than the 2 or 5 year window impact factor.

Auto-correlation of journal impact factor for consensus research reporting statements: a cohort study.

PubMed

Shanahan, Daniel R

2016-01-01

Background. The Journal Citation Reports journal impact factors (JIFs) are widely used to rank and evaluate journals, standing as a proxy for the relative importance of a journal within its field. However, numerous criticisms have been made of use of a JIF to evaluate importance. This problem is exacerbated when the use of JIFs is extended to evaluate not only the journals, but the papers therein. The purpose of this study was therefore to investigate the relationship between the number of citations and journal IF for identical articles published simultaneously in multiple journals. Methods. Eligible articles were consensus research reporting statements listed on the EQUATOR Network website that were published simultaneously in three or more journals. The correlation between the citation count for each article and the median journal JIF over the published period, and between the citation count and number of article accesses was calculated for each reporting statement. Results. Nine research reporting statements were included in this analysis, representing 85 articles published across 58 journals in biomedicine. The number of citations was strongly correlated to the JIF for six of the nine reporting guidelines, with moderate correlation shown for the remaining three guidelines (median r = 0.66, 95% CI [0.45-0.90]). There was also a strong positive correlation between the number of citations and the number of article accesses (median r = 0.71, 95% CI [0.5-0.8]), although the number of data points for this analysis were limited. When adjusted for the individual reporting guidelines, each logarithm unit of JIF predicted a median increase of 0.8 logarithm units of citation counts (95% CI [-0.4-5.2]), and each logarithm unit of article accesses predicted a median increase of 0.1 logarithm units of citation counts (95% CI [-0.9-1.4]). This model explained 26% of the variance in citations (median adjusted r (2) = 0.26, range 0.18-1.0). Conclusion. The impact factor of the

Quotations in Brazilian journals are mainly obtained from national articles (articles from Brazilian journals); thus, it is essential to determine how frequently these articles reference Brazilian journals. This study sought to verify how frequently national papers are cited in the references of three Brazilian physical therapy journals. All references for articles published in Fisioterapia em Movimento, Fisioterapia e Pesquisa and Revista Brasileira de Fisioterapia between 2010 and 2012 were evaluated. In particular, the numbers of national articles and international articles (articles from international journals) cited in these references were determined. A total of 13,009 references cited by 456 articles were analyzed, and 2,924 (22.47%) of the cited works were national articles. There were no significant differences among the three examined years. A total of 36 (7.89%) articles did not cite national articles, whereas 65 (13.25%) articles cited more national articles than international articles. On average, 22.47% of the works cited by the evaluated articles were national articles. No significant differences were detected among the three analyzed years.

One of the most frequently used parameters for evaluating scientific publications is that of impact factor (IF) published in the Science Citation Index-Journal Citation Reports (SCI-JCR) which evaluates the number of citations a journal receives on behalf of other journals. The present study analyzed the Spanish biomedical journals included in the SCI-JCR by the IF. The IF were obtained from the SCI-JCR (1980-89). The journals were evaluated by the IF and the weighted impact factor (WIF) calculated according to WIF = (IF/MIF) x 100 in which MIF = maximum IF of the considered area. Nine Spanish biomedical journals were included in the SCI-JCR, four being basic sciences (Histology and Histopathology, Inmunología, Methods and Findings in Experimental and Clinical Pharmacology, Revista Española de Fisiología) and five clinical journals (Allergologia et Immunopathologia, Medicina Clínica, Nefrología, Revista Española de las Enfermedades del Aparato Digestivo, Revista Clínica Española). Their IF were much lower than the most important journals in each area with the mean (+/- standard deviation) being 0.21 +/- 0.22 (range 0.016-0.627). The mean WIF was 2.88 +/- 4.07 (0.16-12.82). The journals of basic sciences had higher IF and WIF than the clinical journals (p less than 0.05). Only the four journals of basic sciences were included in the SCI. Four journals, those of basic sciences, are preferentially or exclusively published in English and other five are published in Spanish. The differences in IF among these groups were not significant (p = 0.06) while those of WIF were significant (p less than 0.05). The number of Spanish biomedical journals in the SCI-JCR has risen from 1 in 1980 to 9 in 1989 with IF which have evolved variably. In mind of impact factor, the contribution of Spanish journals is low, with that of biomedical sciences being higher than that of clinical journals. Language and inclusion in the Science Citation Index may explain, at least in part

Awareness of the latest scientific research and publishing articles in top journals is one of the major concerns of health researchers. In this study, we first introduced top journals of obstetrics and gynecology field based on their Impact Factor (IF), Eigenfactor Score (ES) and SCImago Journal Rank (SJR) indicator indexed in Scopus databases and then the scientometric features of longitudinal changes of SJR in this field were presented. In our analytical and bibiliometric study, we included all the journals of obstetrics and gynecology field which were indexed by Scopus from 1999 to 2013. The scientometric features in Scopus were derived from SCImago Institute and IF and ES were obtained from Journal Citation Report through the Institute for Scientific Information. Generalized Estimating Equation was used to assess the scientometric features affecting SJR. From 256 journals reviewed, 54.2% and 41.8% were indexed in the Pubmed and the Web of Sciences, respectively. Human Reproduction Update based on the IF (5.924±2.542) and SJR (2.682±1.185), and American Journal of obstetrics and gynecology based on the ES (0.05685±0.00633) obtained the first rank among the other journals. Time, Index in Pubmed, H_index, Citable per Document, Cites per Document, and IF affected changes of SJR in the period of study. Our study showed a significant association between SJR and scientometric features in obstetrics and gynecology journals. According to this relationship, SJR may be an appropriate index for assessing journal quality.

Because we believe the journal selection before a manuscript submission deserves further investigation in each medical specialty, we aimed to evaluate the predictive ability of seven bibliometrics in the Radiology, Nuclear Medicine and Medical Imaging category of the Web of Knowledge to calculate total citations over a 7-year period. A linear mixed effects design using random slopes and intercepts were performed on bibliometrics corresponding to 124 journals from 2007 to 2011, with their corresponding citations from 2009 to 2013, which appeared in the Journal Citations Report Science Edition. The Eigenfactor Score, Article Influence Score, Cited Half-life, 5-years impact factor and Number of Articles are significant predictors of 2-year-ahead total citations (p ≤ 0.010 for all variables). The impact factor and Immediacy Index are not significant predictors. There was a significant global effect size (R 2  = 0.934; p < 0.001), which yielded a total variance of 93.4%. Our findings support researchers' decision to stop the misuse of IF alone to evaluate journals. Radiologists and other researchers should review journal's bibliometrics for their decision-making during the manuscript submission phase. A re-ranking of journals using Eigenfactor Score, Article Influence Score, and Cited Half-life provides a better assessment of their significance and importance in particular disciplines.

The Intellectual Structure of Research on Educational Technology in Science Education (ETiSE): A Co-citation Network Analysis of Publications in Selected Journals (2008-2013)

The main purpose of this paper is to investigate the intellectual structure of the research on educational technology in science education (ETiSE) within the most recent years (2008-2013). Based on the criteria for educational technology research and the citation threshold for educational co-citation analysis, a total of 137 relevant ETiSE papers were identified from the International Journal of Science Education, the Journal of Research in Science Teaching, Science Education, and the Journal of Science Education and Technology. Then, a series of methodologies were performed to analyze all 137 source documents, including document co-citation analysis, social network analysis, and exploratory factor analysis. As a result, 454 co-citation ties were obtained and then graphically visualized with an undirected network, presenting a global structure of the current ETiSE research network. In addition, four major underlying intellectual subfields within the main component of the ETiSE network were extracted and named as: (1) technology-enhanced science inquiry, (2) simulation and visualization for understanding, (3) technology-enhanced chemistry learning, and (4) game-based science learning. The most influential co-citation pairs and cross-boundary phenomena were then analyzed and visualized in a co-citation network. This is the very first attempt to illuminate the core ideas underlying ETiSE research by integrating the co-citation method, factor analysis, and the networking visualization technique. The findings of this study provide a platform for scholarly discussion of the dissemination and research trends within the current ETiSE literature.

To review the contributions to ophthalmic genetics through the American Journal of Ophthalmology (AJO). Perspective. A literature search to retrieve original articles, letters, editorials, and published lectures from 1966 to 2017, providing a 50-year review. Titles were excluded that gave no reference to genetics or that presented findings related to a nongenetic ocular condition. From a search of the Scopus database, 719 articles were ascertained. Of these, 115 were excluded because the title did not reference a genetic condition or have a focus on genetic factors; 4 were excluded because they described animal phenotypes (1966-1967); and 4 were excluded owing to having received no citations up to and including 2015. The highest number of citations was 283 times for a single article on familial aggregation in age-related macular degeneration. The Web of Science database yielded 771 articles; of these, 118 were excluded owing to not reporting human genetic studies; 55 received no citations. The highest number of citations was 307 for a single article, a 1991 paper on Leber hereditary optic neuropathy. The Journal's contributions to our understanding of the heritability of human ocular traits have been broad and deep, with international reach. The development of new techniques fostered new concepts and new approaches to rapidly expand the number of known single gene disorders with a defined molecular genetic cause. Reports on Mendelian and complex traits in the AJO abound, along with 6 Edward Jackson Memorial Lectures on retinal dystrophies, Leber congenital amaurosis, age-related macular degeneration, and glaucoma.

Effectiveness of Journal Ranking Schemes as a Tool for Locating Information

Stringer, Michael J.; Sales-Pardo, Marta; Nunes Amaral, Luís A.

2008-01-01

Background The rise of electronic publishing [1], preprint archives, blogs, and wikis is raising concerns among publishers, editors, and scientists about the present day relevance of academic journals and traditional peer review [2]. These concerns are especially fuelled by the ability of search engines to automatically identify and sort information [1]. It appears that academic journals can only remain relevant if acceptance of research for publication within a journal allows readers to infer immediate, reliable information on the value of that research. Methodology/Principal Findings Here, we systematically evaluate the effectiveness of journals, through the work of editors and reviewers, at evaluating unpublished research. We find that the distribution of the number of citations to a paper published in a given journal in a specific year converges to a steady state after a journal-specific transient time, and demonstrate that in the steady state the logarithm of the number of citations has a journal-specific typical value. We then develop a model for the asymptotic number of citations accrued by papers published in a journal that closely matches the data. Conclusions/Significance Our model enables us to quantify both the typical impact and the range of impacts of papers published in a journal. Finally, we propose a journal-ranking scheme that maximizes the efficiency of locating high impact research. PMID:18301760

Background The contents of pharmaceutical industry sponsored supplements to medical journals are perceived to be less credible than the contents of their parent journals. It is unknown if their contents are cited as often. The objective of this study was to quantify the citability of original research and reviews contained in supplements and compare it with that for the parent journal. Methodology/Principal Findings This was a cohort study of 446 articles published in the Journal of Clinical Psychiatry (JCP) and its supplements for calendar years 2000 and 2005. The total citation counts for each article up to October 5, 2009 were retrieved from the ISI Web of Science database. The main outcome measure was the number of citations received by an article since publication. Regular journal articles included 114 from calendar year 2000 and 190 from 2005. Articles from supplements included 90 from 2000 and 52 from 2005. The median citation counts for the 3 years post-publication were 10 (interquartile range [IQR], 4–20), 14 (IQR, 8–20), 13.5 (IQR, 8–23), and 13.5 (IQR, 8–20), for the 2000 parent journal, 2000 supplements, 2005 parent journal, and 2005 supplements, respectively. Citation counts were higher for the articles in the supplements than the parent journal for the cohorts from 2000 (p = .02), and no different for the year 2005 cohorts (p = .88). The 2005 parent journal cohort had higher citation counts than the 2000 cohort (p = .007), in contrast to the supplements where citation counts remained the same (p = .94). Conclusions/Significance Articles published in JCP supplements are robustly cited and thus can be influential in guiding clinical and research practice, as well as shaping critical thinking. Because they are printed under the sponsorship of commercial interests, they may be perceived as less than objective. A reasonable step to help improve this perception would be to ensure that supplements are peer-reviewed in the same way as

Neophilia Ranking of Scientific Journals.

Packalen, Mikko; Bhattacharya, Jay

2017-01-01

The ranking of scientific journals is important because of the signal it sends to scientists about what is considered most vital for scientific progress. Existing ranking systems focus on measuring the influence of a scientific paper (citations)-these rankings do not reward journals for publishing innovative work that builds on new ideas. We propose an alternative ranking based on the proclivity of journals to publish papers that build on new ideas, and we implement this ranking via a text-based analysis of all published biomedical papers dating back to 1946. In addition, we compare our neophilia ranking to citation-based (impact factor) rankings; this comparison shows that the two ranking approaches are distinct. Prior theoretical work suggests an active role for our neophilia index in science policy. Absent an explicit incentive to pursue novel science, scientists underinvest in innovative work because of a coordination problem: for work on a new idea to flourish, many scientists must decide to adopt it in their work. Rankings that are based purely on influence thus do not provide sufficient incentives for publishing innovative work. By contrast, adoption of the neophilia index as part of journal-ranking procedures by funding agencies and university administrators would provide an explicit incentive for journals to publish innovative work and thus help solve the coordination problem by increasing scientists' incentives to pursue innovative work.

Introduction: Awareness of the latest scientific research and publishing articles in top journals is one of the major concerns of health researchers. In this study, we first introduced top journals of obstetrics and gynecology field based on their Impact Factor (IF), Eigenfactor Score (ES) and SCImago Journal Rank (SJR) indicator indexed in Scopus databases and then the scientometric features of longitudinal changes of SJR in this field were presented. Method and material: In our analytical and bibiliometric study, we included all the journals of obstetrics and gynecology field which were indexed by Scopus from 1999 to 2013. The scientometric features in Scopus were derived from SCImago Institute and IF and ES were obtained from Journal Citation Report through the Institute for Scientific Information. Generalized Estimating Equation was used to assess the scientometric features affecting SJR. Result: From 256 journals reviewed, 54.2% and 41.8% were indexed in the Pubmed and the Web of Sciences, respectively. Human Reproduction Update based on the IF (5.924±2.542) and SJR (2.682±1.185), and American Journal of obstetrics and gynecology based on the ES (0.05685±0.00633) obtained the first rank among the other journals. Time, Index in Pubmed, H_index, Citable per Document, Cites per Document, and IF affected changes of SJR in the period of study. Discussion: Our study showed a significant association between SJR and scientometric features in obstetrics and gynecology journals. According to this relationship, SJR may be an appropriate index for assessing journal quality. PMID:25684846

Purpose To examine whether National Institutes of Health (NIH) funded articles that were archived in PubMed Central (PMC) after the release of the 2008 NIH Public Access Policy show greater scholarly impact than comparable articles not archived in PMC. Methods A list of journals across several subject areas was developed from which to collect article citation data. Citation information and cited reference counts of the articles published in 2006 and 2009 from 122 journals were obtained from the Scopus database. The articles were separated into categories of NIH funded, non-NIH funded and whether they were deposited in PubMed Central. An analysis of citation data across a five-year timespan was performed on this set of articles. Results A total of 45,716 articles were examined, including 7,960 with NIH-funding. An analysis of the number of times these articles were cited found that NIH-funded 2006 articles in PMC were not cited significantly more than NIH-funded non-PMC articles. However, 2009 NIH funded articles in PMC were cited 26% more than 2009 NIH funded articles not in PMC, 5 years after publication. This result is highly significant even after controlling for journal (as a proxy of article quality and topic). Conclusion Our analysis suggests that factors occurring between 2006 and 2009 produced a subsequent boost in scholarly impact of PubMed Central. The 2008 Public Access Policy is likely to be one such factor, but others may have contributed as well (e.g., growing size and visibility of PMC, increasing availability of full-text linkouts from PubMed, and indexing of PMC articles by Google Scholar).

transparency in reporting of conflict of interest is an increasingly important aspect of publication in medical journals. Publication of large industry-supported trials may generate many citations and journal income through reprint sales and thereby be a source of conflicts of interest for journals. We investigated industry-supported trials' influence on journal impact factors and revenue. we sampled six major medical journals (Annals of Internal Medicine, Archives of Internal Medicine, BMJ, JAMA, The Lancet, and New England Journal of Medicine [NEJM]). For each journal, we identified randomised trials published in 1996-1997 and 2005-2006 using PubMed, and categorized the type of financial support. Using Web of Science, we investigated citations of industry-supported trials and the influence on journal impact factors over a ten-year period. We contacted journal editors and retrieved tax information on income from industry sources. The proportion of trials with sole industry support varied between journals, from 7% in BMJ to 32% in NEJM in 2005-2006. Industry-supported trials were more frequently cited than trials with other types of support, and omitting them from the impact factor calculation decreased journal impact factors. The decrease varied considerably between journals, with 1% for BMJ to 15% for NEJM in 2007. For the two journals disclosing data, income from the sales of reprints contributed to 3% and 41% of the total income for BMJ and The Lancet in 2005-2006. publication of industry-supported trials was associated with an increase in journal impact factors. Sales of reprints may provide a substantial income. We suggest that journals disclose financial information in the same way that they require them from their authors, so that readers can assess the potential effect of different types of papers on journals' revenue and impact.

The Revista de Biología Tropical / International Journal of Tropical Biology and Conservation, founded in 1953, publishes feature articles about tropical nature and is considered one of the leading journals in Latin America. This article analyzes document type, language, countries, institutions, citations and for the first time article lifespan, from 1976 through 2014. We analyzed 3 978 documents from the Science Citation Index Expanded. Articles comprised 88 % of the total production and had 3.7 citations on average, lower than reviews. Spanish and English articles were nearly equal in numbers and citation for English articles was only slightly higher. Costa Rica, Mexico, and the USA are the countries with more articles, and the leading institutions were Universidad de Costa Rica, Universidad Nacional, Universidad Nacional Autónoma de Mexico and Universidad de Oriente (Venezuela). The citation lifespan of articles is long, around 37 years. It is not surprising that Costa Rica, Mexico, and Venezuela lead in productivity and cooperation, because they are mostly covered by tropical ecosystems and share a common culture and a tradition of scientific cooperation. The same applies to the leading institutions, which are among the largest Spanish language universities in the neotropical region. American output can be explained by the regional presence of the Smithsonian Tropical Research Institute and the Organization for Tropical Studies. Tropical research does not have the rapid change typical of medical research, and for this reason, the impact factor misses most of citations for the Revista, which are made after the two-year window used by the Web of Science. This issue is especially damaging for the Revista because most journals that deal with tropical biology are never checked when citations are counted for by the Science Citation Index.

Asnafi, Solmaz; Gunderson, Tina; McDonald, Robert J; Kallmes, David F

2017-02-01

h-Index has been proposed as a useful bibliometric measure for quantifying research productivity. In this current study, we analyzed h-indices of editorial board members of Radiology journals and tested the hypothesis that editorial board members of Radiology journals with higher impact factors (IF) have higher h-indices. Sixty-two Radiology journals with IF >1 were included. Editorial board members were identified using the journals' websites. Editors' affiliations and research fields of interest were used to distinguish investigators with similar names. Bibliometric indices including number of publications, total citations, citations per publication, and h-index for each editorial board member were obtained using the Web of Science database. Chi-square or Wilcoxon rank-sum tests were used to test for differences in bibliographic measures or demographics between groups. Among the editorial boards of 62 journals, the median [interquartile range] board h-index was 26 [18, 31] and had 36 [17, 56] members. The median journal IF was 2.27 [1.74, 3.31]. We identified a total of 2204 distinct editors; they had a median [interquartile range] h-index of 23 [13, 35], 120 [58, 215] total publications, 1938 [682, 4634] total citations, and an average of 15.7 [9.96, 24.8] citations per publication. The boards of journals with IF above the median had significantly higher h-indices (P = .002), total publications (P = .01), and total and average citations (both any [P = .003, .009] and nonself-citations [P = .001, .002]) than journals below the median. Our data indicate that board members of Radiology journals with higher IF have greater h-indices compared to lower IF journals. Copyright © 2017 The Association of University Radiologists.

Recent changes in the landscape of scientific publishing prompted the Publications Overview Committee of the American Fisheries Society (AFS) to review the Society's portfolio of scientific journals. We evaluated journals based on metrics in two categories: (1) citation-based measures of the influence of a journal on the scientific literature, and (2) measures of the cost-effectiveness of a journal (citation rate adjusted for subscription cost). Over the long-term, we found that ecology journals had far stronger citation-based influence than fisheries and aquatic sciences journals, and that journals publishing primarily basic research had stronger influence than journals publishing applied research (including four AFS journals and Fisheries magazine). In evaluating the current status of fisheries and aquatic sciences journals, we found that metrics of influence and cost-effectiveness provided considerably different portrayals of journals relative to their peers. In terms of citation-based influence, we found that the AFS journal Transactions of the American Fisheries Society (TAFS) and Fisheries magazine were competitive with highly regarded peer fisheries journals, but that North American Journal of Aquaculture (NAJA) and Journal of Aquatic Animal Health (JAAH) were less influential than their peers. The citation-based influence of North American Journal of Fisheries Management (NAJFM) was intermediate between TAFS/Fisheries and NAJA/JAAH. For journals like NAJFM and NAJA, we expect that much of the scientific influence on policy and management is not captured by citations in the primary literature, and alternative methods of evaluation may be needed. All of the AFS journals ranked highly with regard to cost-effectiveness because their subscription costs are low, and these rankings are in accordance with membership needs and the strategic mission of AFS to provide broad and timely dissemination of scientific information. We conclude by suggesting

To assess whether there is a preference for international journal citation to the detriment of national ones in ten Brazilian medical journals, in two different periods. All references in the articles published in Arquivos Brasileiros de Oftalmologia, Revista Brasileira de Cirurgia Cardiovascular, Revista da Associação Médica Brasileira, São Paulo Medical Journal, Arquivos Brasileiros de Endocrinologia e Metabologia, Clinics, Jornal Brasileiro de Pneumologia, Revista da Sociedade Brasileira de Medicina Tropical, Revista Brasileira de Psiquiatria e Acta Ortopédica Brasileira in the years 2011 and 2007 were analyzed, assessing the number of articles published in national and international journals. A total of 36,125 references from 1,462 articles published in the 10 aforementioned journals were analyzed. Of the total number, 4.242 (11.74%) were from Brazilian journals. There was no significant difference between the two analyzed periods. A total of 453 (30,98%) of the articles studied non-cited brazilian papers,and 81 (5.54%) articles had more Brazilian than international references. Of total references analyzed, 11.74% were related to articles published in Brazilian journals. This number, when compared to the percentage of Brazilian articles published in the medical area, demonstrates a good number of citations of national articles. Copyright © 2012 Elsevier Editora Ltda.

1993-02-01

The accuracy of references and quotations used to substantiate statements of fact in articles published in 6 frequently cited veterinary journals was examined. Three hundred references were randomly selected, and the accuracy of each citation was examined. A subset of 100 references was examined for quotational accuracy; ie, the accuracy with which authors represented the work or assertions of the author being cited. Of the 300 references selected, 295 were located, and 125 major errors were found in 88 (29.8%) of them. Sixty-seven (53.6%) major errors were found involving authors, 12 (9.6%) involved the article title, 14 (11.2%) involved the book or journal title, and 32 (25.6%) involved the volume number, date, or page numbers. Sixty-eight minor errors were detected. The accuracy of 111 quotations from 95 citations in 65 articles was examined. Nine quotations were technical and not classified, 86 (84.3%) were classified as correct, 2 (1.9%) contained minor misquotations, and 14 (13.7%) contained major misquotations. We concluded that misquotations and errors in citations occur frequently in veterinary journals, but at a rate similar to that reported for other biomedical journals.

We assessed the relationship between the size of the 39 Journal Citation Reports (JCR) medical categories and impact factor (IF) of journals in these categories, and the implications that it might have for emergency medicine (EM) journals. Using the 2010 JCR database, we calculated the mean IF, 5-year IF (5y-IF), Eigenfactor (EF), and Article Influence (AI) scores including all journals for each category. We also calculated a 'weighted IF' for all journals by dividing each journal IF by the mean IF of its category. We ranked EM journals according to IF and 'weighted IF' into all the journals included in the 39 categories. We assessed the relationship between category size and bibliometric scores by linear regression. Category size varied from 252 journals (Pharmacology and Pharmacy) to 14 (Primary Healthcare), EM category occupying the 36th position (23 journals). The mean IF of EM category ranked in 34th position, 5-yIF in 32nd, EF in 34th, and AI in 34th position. Category size had a direct and significant association with mean IF, 5y-IF, and AI but not with mean EF. When the EM journals were ranked among all the journals according to their IF, only two (9%) were placed into the first quartile and raised up to eight (35%) when 'weighted IF' was considered. There is a negative relationship between JCR size category and IF achieved by the journals. This places EM journals at a clear disadvantage because they represent one of the smallest clinical medical research disciplines.

AGU journals continue to rank highly in many categories in the 2010 Journal Citation Report (JCR), which was released by Thomson Reuters on 28 June. JCR reports on several measures of journal usage, including a journal's Eigenfactor score, its Article Influence score, its Impact Factor, and its rank within a cohort of similar journals. According to the 2010 statistics, AGU again has outperformed its larger competitors. Four different AGU titles are ranked in the top three journals in six different cohorts. The Impact Factor of several AGU journals increased significantly over the previous year.

Promotion of Neurointervention to International Journal Based on Journal Metrics

PubMed Central

2016-01-01

Purpose The aim is to provide evidence of the internationalization of Neurointervention based on journal metrics for articles published from 2011 to 2015. Materials and Methods The following metrics and data were collected and analyzed with descriptive statistics: number of citable and non-citable articles; number of research articles (original papers) supported by grants; editorial board members' countries; authors' countries; citing authors' countries; source title of citing articles; two-year impact factor; total citations; and Hirsch index (h-index). Data were retrieved and analyzed from the journal homepage and Web of Science Core Collection in January 24, 2016. Results There were 80 citable and eight non-citable articles from 2011 to 2015. Out of 31 original articles, nine had research funds (29.0%). Editorial board members are from five countries. The authors are from six countries. The top-ranking countries of citing authors were USA, Korea, and China. The two-year impact factors were 1.125, 0.923, and 0.931 from 2013 to 2015. H-index was 7. Conclusion It was possible to confirm the internationalization of Neurointervention based on journal metrics. New digital standards should be adopted for more rapid dissemination of journal content.

The citation climate in neurosurgical literature is largely undefined. To study the patterns of citation of articles in neurosurgery as a scientific field and to evaluate the performance of neurosurgery journals vis-à-vis journals in other fields. References cited in articles published in neurosurgery journals during a specified time period were analyzed to determine the age of articles cited in neurosurgical literature. In the next analysis, articles published in neurosurgical journals were followed up for 13 years after publication. The postpublication citation patterns were analyzed to determine the time taken to reach the maximally cited state and the time when articles stopped being cited. The final part of the study dealt with the evolution of a new interfield citation metric, which was then compared with other standardized citation indexes. The mean ± SD age of articles cited in neurosurgical literature was 11.6 ± 11.7 years (median, 8 years). Citations received by articles gradually increased to a peak (at 6.25 years after publication in neurosurgery) and then reached a steady state; articles were still cited well into the late postpublication period. Neurosurgical articles published in nonneurosurgical high-impact journals were cited more highly than those in neurosurgical journals, although they took approximately the same time to reach the maximally cited state (7.2 years). The most cited pure neurosurgery journal was Neurosurgery. The citation climate for neurosurgery was adequately described. The interfield citation metric was able to ensure cross-field comparability of journal performance. G1, group 1G2, group 2G3, group 3G4, group 4IFCM, interfield citation metric.

Publishing articles in a prestigious journal is a golden rule for university professors and researchers nowadays. Impact factor, journal rank, and citation count, included in Science Citation Index managed by Thomson Reuters Web of Science, are the most important indicators for evaluating the quality of academic journals. By listing the journals encompassed in the "Integrative and Complementary Medicine" category of Science Citation Index from 2003 to 2013, this paper examines the publication trends of journals in the category. The examination includes number, country of origin, ranking, and languages of journals. Moreover, newly listed or removed journals in the category, journal publishers, and open access strategies are examined. It is concluded that the role of journal publisher should not be undermined in the "Integrative and Complementary Medicine" category.

The ability to identify scientific journals that publish high-quality research would help clinicians, scientists, and health-policy analysts to select the most up-to-date medical literature to review. To assess whether journal characteristics of (1) peer-review status, (2) citation rate, (3) impact factor, (4) circulation, (5) manuscript acceptance rate, (6) MEDLINE indexing, and (7) Brandon/Hill Library List indexing are predictors of methodological quality of research articles, we conducted a cross-sectional study of 243 original research articles involving human subjects published in general internal medical journals. The mean (SD) quality score of the 243 articles was 1.37 (0.22). All journals reported a peer-review process and were indexed on MEDLINE. In models that controlled for article type (randomized controlled trial [RCT] or non-RCT), journal citation rate was the most statistically significant predictor (0.051 increase per doubling; 95% confidence interval [CI], 0.037-0.065; P<.001). In separate analyses by article type, acceptance rate was the strongest predictor for RCT quality (-0.113 per doubling; 95% CI, -0.148 to -0.078; P<.001), while journal citation rate was the most predictive factor for non-RCT quality (0.051 per doubling; 95% CI, 0.044-0.059; P<.001). High citation rates, impact factors, and circulation rates, and low manuscript acceptance rates and indexing on Brandon/Hill Library List appear to be predictive of higher methodological quality scores for journal articles.

The research-related performance of universities, as well as that of individual researchers, is increasingly evaluated through the use of objective measures, or metrics, which seek to support or in some cases even replace more traditional methods of peer review. In particular there is a growing awareness in research communities, government organisations and funding bodies around the concept of using evaluation metrics to analyse research citations. The tools available for 'citation analysis' are many and varied, enabling a quantification of scientific quality, academic impact and prestige. However there is increasing concern regarding the potential misuse of such tools, which have limitations in certain research disciplines.This article uses 'real world' examples from radiography research and scholarship to illustrate the range of currently available citation analysis tools. It explores the academic debate surrounding their strengths and limitations, and identifies the potential impact of citation analysis on the radiography research community.The article concludes that citation analysis is a valuable tool for researchers to use for personal reflection and research planning, yet there are inherent dangers if it is used inappropriately. Whilst citation analysis can give objective information regarding an individual, research group, journal or higher education institution, it should not be used as a total substitute for traditional qualitative review and peer assessment.

Local and regional scientific journals are important factors in bridging gaps in health knowledge translation in low-and middle-income countries. We assessed indexing, citations and publishing standards of journals from the Eastern Mediterranean region. For journals from 22 countries in the collection of the Index Medicus for the Eastern Mediterranean Region (IMEMR), we analyzed indexing in bibliographical databases and citations during 2006-2009 to published items in 2006 in Web of Science (WoS) and SCOPUS. Adherence to editorial and publishing standards was assessed using a special checklist. Out of 419 journals in IMEMR, 19 were indexed in MEDLINE, 23 in WoS and 46 in SCOPUS. Their impact factors ranged from 0.016 to 1.417. For a subset of 175 journals with available tables of contents from 2006, articles published in 2006 from 93 journals received 2068 citations in SCOPUS (23.5% self-citations) and articles in 86 journals received 1579 citations in WoS (24.3% self-citations) during 2006-2009. Citations to articles came mostly from outside of the Eastern Mediterranean region (76.8% in WoS and 75.4% in SCOPUS). Articles receiving highest number of citations presented topics specific for the region. Many journals did not follow editorial and publishing standards, such addressing requirements about the patient's privacy rights (68.0% out of 244 analyzed), policy on managing conflicts of interest (66.4%), and ethical conduct in clinical and animal research (66.4%). Journals from the Eastern Mediterranean are visible in and have impact on global scientific community. Coordinated effort of all stakeholders in journal publishing, including researchers, journal editors and owners, policy makers and citation databases, is needed to further promote local journals as windows to the research in the developing world and the doors for valuable regional research to the global scientific community.

Lundh, Andreas; Barbateskovic, Marija; Hróbjartsson, Asbjørn; Gøtzsche, Peter C.

2010-01-01

Background Transparency in reporting of conflict of interest is an increasingly important aspect of publication in medical journals. Publication of large industry-supported trials may generate many citations and journal income through reprint sales and thereby be a source of conflicts of interest for journals. We investigated industry-supported trials' influence on journal impact factors and revenue. Methods and Findings We sampled six major medical journals (Annals of Internal Medicine, Archives of Internal Medicine, BMJ, JAMA, The Lancet, and New England Journal of Medicine [NEJM]). For each journal, we identified randomised trials published in 1996–1997 and 2005–2006 using PubMed, and categorized the type of financial support. Using Web of Science, we investigated citations of industry-supported trials and the influence on journal impact factors over a ten-year period. We contacted journal editors and retrieved tax information on income from industry sources. The proportion of trials with sole industry support varied between journals, from 7% in BMJ to 32% in NEJM in 2005–2006. Industry-supported trials were more frequently cited than trials with other types of support, and omitting them from the impact factor calculation decreased journal impact factors. The decrease varied considerably between journals, with 1% for BMJ to 15% for NEJM in 2007. For the two journals disclosing data, income from the sales of reprints contributed to 3% and 41% of the total income for BMJ and The Lancet in 2005–2006. Conclusions Publication of industry-supported trials was associated with an increase in journal impact factors. Sales of reprints may provide a substantial income. We suggest that journals disclose financial information in the same way that they require them from their authors, so that readers can assess the potential effect of different types of papers on journals' revenue and impact.

Bibliometric analysis of the American Journal of Veterinary Research to produce a list of core veterinary medicine journals

PubMed Central

Crawley-Low, Jill

2006-01-01

Objective: Bibliometric techniques were used to analyze the citation patterns of researchers publishing in the American Journal of Veterinary Research (AJVR). Methods: The more than 25,000 bibliographic references appearing in the AJVR from 2001 to 2003 were examined for material type, date of publication, and frequency of journals cited. Journal titles were ranked in decreasing order of productivity to create a core list of journals most frequently used by veterinary medical researchers. Results: The majority of items cited were journals (88.8%), followed by books (9.8%) and gray literature (2.1%). Current sources of information were favored; 65% of the journals and 77% of the books were published in 1990 or later. Dividing the cited articles into 3 even zones revealed that 24 journals produced 7,361 cited articles in the first zone. One hundred thirty-nine journals were responsible for 7,414 cited articles in zone 2, and 1,409 journals produced 7,422 cited articles in zone 3. Conclusions: A core collection of veterinary medicine journals would include 49 veterinary medicine journals from zones 1 and 2. Libraries supporting a veterinary curriculum or veterinary research should also include veterinary medical journals from Zone 3, as well as provide access to journals in non-veterinary subjects such as biochemistry, virology, orthopedics, and surgery and a selection of general science and medical journals.

2007-04-01

Latin American medical journals have a low impact factor. Higher quality articles originated in Latin American countries are published in North American or European journals. To analyze the impact factor of Latin-American journals according to the language of publication. The data base of periodic journals of the Thomson ISI (Journal of Citation Report) in the year 2004 was used for the analysis. Four countries with more than one journal in the data base of the Thomson ISI were included (Argentina, Brazil, Chile and Mexico). Few Latin-American journals are included in the Thomson ISI data base. The mean impact factor was 0.76 (0.23-3.2) for eight Mexican journals, 0.66 (0.10-2.1) for eight Chilean journals, 0.39 (0.06-0.7) for five Argentinian journals and 0.41 (0.09-1.1) for 16 Brazilian journals. The mean impact factor for 11 journals written in English was 0.74 (0.12-2.1), 0.53 (0.09-3.2) for 18 bilingual journals and 0.28 (0.06-0.56) for eight journals written in native language. The differences between countries and languages were not statistically significant. The journal impact factor was similar in the four countries studied. A non-significant higher impact factor was observed in Latin-American journals published in English.

The Structure of Medical Informatics Journal Literature

Abstract Objective: Medical informatics is an emergent interdisciplinary field described as drawing upon and contributing to both the health sciences and information sciences. The authors elucidate the disciplinary nature and internal structure of the field. Design: To better understand the field's disciplinary nature, the authors examine the intercitation relationships of its journal literature. To determine its internal structure, they examined its journal cocitation patterns. Measurements: The authors used data from the Science Citation Index (SCI) and Social Science Citation Index (SSCI) to perform intercitation studies among productive journal titles, and software routines from SPSS to perform multivariate data analyses on cocitation data for proposed core journals. Results: Intercitation network analysis suggests that a core literature exists, one mark of a separate discipline. Multivariate analyses of cocitation data suggest that major focus areas within the field include biomedical engineering, biomedical computing, decision support, and education. The interpretable dimensions of multidimensional scaling maps differed for the SCI and SSCI data sets. Strong links to information science literature were not found. Conclusion: The authors saw indications of a core literature and of several major research fronts. The field appears to be viewed differently by authors writing in journals indexed by SCI from those writing in journals indexed by SSCI, with more emphasis placed on computers and engineering versus decision making by the former and more emphasis on theory versus application (clinical practice) by the latter.

Bibliometric study of grey literature in core veterinary medical journals.

PubMed

Pelzer, Nancy L; Wiese, William H

2003-10-01

Grey literature has been perceived by many as belonging to the primary sources of information and has become an accepted method of nonconventional communication in the sciences and medicine. Since little is known about the use and nature of grey literature in veterinary medicine, a systematic study was done to analyze and characterize the bibliographic citations appearing in twelve core veterinary journals. Citations from 2,159 articles published in twelve core veterinary journals in 2000 were analyzed to determine the portion of citations from grey literature. Those citations were further analyzed and categorized according to the type of publication. Citation analysis yielded 55,823 citations, of which 3,564 (6.38%) were considered to be grey literature. Four veterinary specialties, internal medicine, pathology, theriogenology, and microbiology, accounted for 70% of the total number of articles. Three small-animal clinical practice journals cited about 2.5-3% grey literature, less than half that of journals with basic research orientations, where results ranged from almost 6% to approximately 10% grey literature. Nearly 90% of the grey literature appeared as conferences, government publications, and corporate organization literature. The results corroborate other reported research that the incidence of grey literature is lower in medicine and biology than in some other fields, such as aeronautics and agriculture. As in other fields, use of the Internet and the Web has greatly expanded the communication process among veterinary professionals. The appearance of closed community email forums and specialized discussion groups within the veterinary profession is an example of what could become a new kind of grey literature.

2008-08-15

Pharmacy-focused journals that are available in open-access (OA), freely accessible, hybrid, or traditional formats were identified. Relevant journals were accessed from PubMed, International Pharmaceutical Abstracts, EMBASE, and the Pharmacology and Pharmacy category of Thomson Scientific Journal Citation Reports. Criteria were established to select journals that satisfied the definition of pharmacy focused. Journals were assessed based on accessibility, copyright transfer requirements, and restrictions. If tracked, the journal's impact factor (IF) was identified according to classification, and medians were calculated for each journal category. A total of 317 pharmacy-focused journals were identified. The majority of pharmacy-focused journals identified were traditional/non-OA (n = 240). A smaller number of journals were freely accessible/ non-OA (n = 37), freely accessible/non-OA with content restrictions (n = 20), or freely available/non-OA with date restrictions (n = 18). The fewest number of journals were completely OA (n = 2). The median IF for the 185 journals whose IF was tracked was 2.029. The median IF for freely accessible and hybrid journals (n = 42) was 2.550, whereas the median IF for traditional journals (n = 143) was 1.900. A very small number of pharmacy-focused journals adhere to the OA paradigm of access. However, journals that adopt some elements of the OA model, chiefly free accessibility, may be more likely to be cited than traditional journals. Pharmacy practitioners, educators, and researchers could benefit from the advantages that OA offers but should understand its financial disadvantages.

Journals are currently assessed and ranked using a number of different quantitative performance metrics. To compare and correlate the publication metrics of English-language occupational therapy journals published in 2015. Bibliometric data was sourced for 14 English-language occupational therapy journals including the Journal Citations Report (JCR) 2-year impact factor (IF), Eigenfactor Score (EFS), Article Influence Score (AIS), Scopus Source Normalized Impact per Paper (SNIP), Scopus Citescore, and SCImago Journal Rank (SJR) score. The JCR, Scopus, and SJR 2015 bibliometric data were correlated. The top six English-language occupational therapy journals in relation to JCR IF, EFS, AIS, SNIP, Citescore, SJR score, and SJR IIF were AJOT, AOTJ, POPT, CJOT, SJOT, and BJOT. JCR IF, EFS, JCR AIS, SNIP, Citescore, SJR score and SJR IIF were all significantly correlated with coefficients ranging from 0.751 to 0.961 (p < 0.05; p < 0.01). The calculated SJR IIF was on average 0.335 larger than the JCR IFs reported. The findings indicate that the range of available bibliometric measures should be used collectively to yield a more comprehensive assessment of journal and article rankings rather than the singular use of IF scores that currently and frequently occurs in many jurisdictions.

Rising Publication Delays Inflate Journal Impact Factors

Tort, Adriano B. L.; Targino, Zé H.; Amaral, Olavo B.

2012-01-01

Journal impact factors have become an important criterion to judge the quality of scientific publications over the years, influencing the evaluation of institutions and individual researchers worldwide. However, they are also subject to a number of criticisms. Here we point out that the calculation of a journal’s impact factor is mainly based on the date of publication of its articles in print form, despite the fact that most journals now make their articles available online before that date. We analyze 61 neuroscience journals and show that delays between online and print publication of articles increased steadily over the last decade. Importantly, such a practice varies widely among journals, as some of them have no delays, while for others this period is longer than a year. Using a modified impact factor based on online rather than print publication dates, we demonstrate that online-to-print delays can artificially raise a journal’s impact factor, and that this inflation is greater for longer publication lags. We also show that correcting the effect of publication delay on impact factors changes journal rankings based on this metric. We thus suggest that indexing of articles in citation databases and calculation of citation metrics should be based on the date of an article’s online appearance, rather than on that of its publication in print.

The relationship between manuscript title structure and success: editorial decisions and citation performance for an ecological journal

A poorly chosen article title may make a paper difficult to discover or discourage readership when discovered, reducing an article's impact. Yet, it is unclear how the structure of a manuscript's title influences readership and impact. We used manuscript tracking data for all manuscripts submitted to the journal Functional Ecology from 2004 to 2013 and citation data for papers published in this journal from 1987 to 2011 to examine how title features changed and whether a manuscript's title structure was predictive of success during the manuscript review process and/or impact (citation) after publication. Titles of manuscripts submitted to Functional Ecology became marginally longer (after controlling for other variables), broader in focus (less frequent inclusion of genus and species names), and included more humor and subtitles over the period of the study. Papers with subtitles were less likely to be rejected by editors both pre- and post-peer review, although both effects were small and the presence of subtitles in published papers was not predictive of citations. Papers with specific names of study organisms in their titles fared poorly during editorial (but not peer) review and, if published, were less well cited than papers whose titles did not include specific names. Papers with intermediate length titles were more successful during editorial review, although the effect was small and title word count was not predictive of citations. No features of titles were predictive of reviewer willingness to review papers or the length of time a paper was in peer review. We conclude that titles have changed in structure over time, but features of title structure have only small or no relationship with success during editorial review and post-publication impact. The title feature that was most predictive of manuscript success: papers whose titles emphasize broader conceptual or comparative issues fare better both pre- and post-publication than do papers with organism

Citation analysis elucidates patterns of information consumption within professional communities. The aim of this study was to analyze the citations of 87 Spanish medical journals by calculating their impact factors and immediacy indices for 2001, and to estimate the importance of Archivos de Bronconeumología within the framework of Spanish medicine. Eighty-seven Spanish medical journals were included. All were listed in the Spanish Medical Index (Indice Medico Español) and in at least one of the following databases: MEDLINE, BIOSIS, EMBASE, or Science Citation Index. References to articles from 1999 through 2001 in citable articles from 2001 were analyzed. Using the method of the Institute for Scientific Information, we calculated the national impact factor and immediacy index for each journal. The journals with the highest national impact factors were Revista Española de Quimioterapia (0.894), Medicina Clínica (0.89), and Archivos de Bronconeumología (0.732). The self-citation percentage of Archivos de Bronconeumología was 18.3% and the immediacy index was 0.033. The impact factor obtained by Archivos de Bronconeumología confirms its importance in Spanish medicine and validates its inclusion as a source journal in Science Citation Index and Journal Citation Report.

Bradford's law describes the scatter of citations for a given subject or field. It can be used to identify the most highly cited journals for a field or subject. The objective of this study was to use currently accepted formulations of Bradford's law to identify core journals of neurosurgery and neurosurgical subspecialties. All original research publications from 2009 to 2013 were analyzed for the top 25 North American academic neurosurgeons from each subspecialty. The top 25 were chosen from a ranked career h-index list identified from previous studies. Egghe's formulation and the verbal formulation of Bradford's law were applied to create specific citation density zones and identify the core journals for each subspecialty. The databases were then combined to identify the core journals for all of academic neurosurgery. Using Bradford's verbal law with 4 zone models, the authors were able to identify the core journals of neurosurgery and its subspecialties. The journals found in the most highly cited first zone are presented here as the core journals. For neurosurgery as a whole, the core included the following journals: Journal of Neurosurgery, Neurosurgery, Spine, Stroke, Neurology, American Journal of Neuroradiology, International Journal of Radiation Oncology Biology Physics, and New England Journal of Medicine. The core journals for each subspecialty are presented in the manuscript. Bradford's law can be used to identify the core journals of neurosurgery and its subspecialties. The core journals vary for each neurosurgical subspecialty, but Journal of Neurosurgery and Neurosurgery are among the core journals for each neurosurgical subspecialty.

Randomised controlled trials (RCTs) are the gold standard for measuring the efficacy of any medical intervention. The present study assesses the implementation of the CONSORT statement in the top 11 anaesthesiology journals in 2011. We designed this study in order to determine how well authors in the top 11 ranked anaesthesiology journals follow the CONSORT statement's criteria. A retrospective cross-sectional data analysis. The study was performed at the RWTH Aachen University Hospital. Journals included Pain, Anesthesiology, British Journal of Anaesthesia, Regional Anesthesia and Pain Medicine, European Journal of Pain, Anesthesia and Analgesia, Anaesthesia, Minerva Anestesiologica, Canadian Journal of Anesthesia, Journal of Neurosurgical Anesthesiology and the European Journal of Anaesthesiology. All articles in the online table of contents from the top 11 anaesthesiology journals according to the ISI Web of Knowledge were screened for RCTs published in 2011. The RCTs were assessed using the CONSORT checklist. We also analysed the correlation between the number of citations and the adherence to CONSORT items. We evaluated 319 RCTs and found that, more than ten years after the publication of the CONSORT statement, the RCTs satisfied a median of 60.0% of the CONSORT criteria. Only 72.1% of the articles presented clearly defined primary and secondary outcome parameters. The number of citations is only weakly associated with the fulfilment of the CONSORT statement (r = 0.023). Adherence to the CONSORT criteria remains low in top-ranked anaesthesiology journals. We found only a very weak correlation between the number of citations and fulfilment of the requirements of the CONSORT statement.

Objectives: Grey literature has been perceived by many as belonging to the primary sources of information and has become an accepted method of nonconventional communication in the sciences and medicine. Since little is known about the use and nature of grey literature in veterinary medicine, a systematic study was done to analyze and characterize the bibliographic citations appearing in twelve core veterinary journals. Methods: Citations from 2,159 articles published in twelve core veterinary journals in 2000 were analyzed to determine the portion of citations from grey literature. Those citations were further analyzed and categorized according to the type of publication. Results: Citation analysis yielded 55,823 citations, of which 3,564 (6.38%) were considered to be grey literature. Four veterinary specialties, internal medicine, pathology, theriogenology, and microbiology, accounted for 70% of the total number of articles. Three small-animal clinical practice journals cited about 2.5–3% grey literature, less than half that of journals with basic research orientations, where results ranged from almost 6% to approximately 10% grey literature. Nearly 90% of the grey literature appeared as conferences, government publications, and corporate organization literature. Conclusions: The results corroborate other reported research that the incidence of grey literature is lower in medicine and biology than in some other fields, such as aeronautics and agriculture. As in other fields, use of the Internet and the Web has greatly expanded the communication process among veterinary professionals. The appearance of closed community email forums and specialized discussion groups within the veterinary profession is an example of what could become a new kind of grey literature. PMID:14566374

2016-05-01

This study aimed to assess the most common publication types in radiology journals, as well as temporal trends and association with citation frequency. PubMed was searched to extract all published articles having the following "Publication Type" indices: "validation studies," "meta-analysis," "clinical trial," "comparative study," "evaluation study," "guideline," "multicenter study," "randomized study," "review," "editorial," "case report," and "technical report." The percentage of articles within each category published within clinical radiology journals was computed. Normalized percentages for each category were also computed on an annual basis. Citation counts within a 2-year window following publication were obtained using Web of Science. Overall trends were assessed. Publication types with the highest fraction in radiology journals were technical reports, evaluation studies, and case reports (4.8% to 5.8%). Publication types with the lowest fraction in radiology journals were randomized trials, multicenter studies, and meta-analyses (0.8% to 1.5%). Case reports showed a significant decrease since 1999, with accelerating decline since 2007 (P = 0.002). Publication types with highest citation counts were meta-analyses, guidelines, and multicenter studies (8.1 ± 10.7 to 12.9 ± 5.1). Publication types with lowest citation counts were case reports, editorials, and technical reports (1.4 ± 2.4 to 2.9 ± 4.3). The representation in radiology journals and citation frequency of the publication types showed weak inverse correlation (r = -0.372). Radiology journals have historically had relatively greater representation of less frequently cited publication types. Various strategies, including methodological training, multidisciplinary collaboration, national support networks, as well as encouragement of higher level of evidence by funding agencies and radiology journals themselves, are warranted to improve the impact of radiological research

To test whether there is an association between the growth in the number of ophthalmic journals in the past years and their mean and maximum impact factor (IF) as a common sign of scientific proliferation. Using data from the 2013 Journal Citation Report database a study of the major clinical medical fields was conducted to assess the correlation between the number of journals and maximum IF in a given field in the year 2013. In the field of ophthalmology, we examined the correlation between year, number of journals, mean IF and maximum IF in the field of ophthalmology throughout the years 2000-2013. In the major medical fields, a positive correlation was found between the number of journals and the maximum IF (quadratic R2 = 0.71, P< 0.001). When studying the field of ophthalmology a positive correlation between the number of journals and mean IF (R2 = 0.84, P< 0.001) and between number of journals and maximum IF (R2 = 0.71, P< 0.001) was detected. Our findings suggest that the variation in the IF can be explained by the number of journals in the field of ophthalmology. In the future, the formation of additional ophthalmology journals is likely to further increase the IFs of existing journals.

Studies have demonstrated strong associations between publication source and citations, as well as investigatory analysis of collaboration effects, in general and medical literature, but are limited to specific journals or short duration of time. This study sought to analyze time trends in cardiovascular research publications in leading general and specialty journals and to determine the association between collaboration and citation index. Cardiovascular publications were retrieved from Web of Knowledge by a cardiovascular bibliometric filter, and annual publication volumes in 8 general and specialty journals were compared. Univariable linear regression models were used to determine global and journal-specific trends for overall publication, cardiovascular publication, proportion of cardiovascular publication, collaboration, and citations. Cardiovascular publications increased (1999 to 2008) by 36% and number of sources by 74%. Volume increased in European Heart Journal (beta: 18.4, 95% confidence interval [CI]: 10.6 to 26.3) and decreased in Circulation (beta: -42.9, 95% CI: -79.3 to -6.5), Annals of Internal Medicine (beta: -1.9, 95% CI: -3.5 to -0.3), and Lancet (beta: -11.2, 95% CI: -14.7 to -7.8). Number of contributing countries increased in 3 journals: BMJ (beta: 0.8, 95% CI: 0.2 to 1.5), European Heart Journal (beta: -1.2, 95% CI: 0.8 to 1.7), and New England Journal of Medicine (beta: 1.6, 95% CI: 0.6 to 2.7). Fraction of collaborative publications increased (beta: 1.1 to 2.9) in all but Annals of Internal Medicine. Collaboration was associated with a higher median actual citation index (p < 0.0001). We found increasing trends in collaboration and citation in both general and specialty journals. Contribution by country in selected journals was disproportionate and under-represents total cardiovascular research in low- and middle-income countries.

Articles from open access and local journals are important resources for research in Korea and the usage trends of these articles are important indicators for the assessment of the current research practice. We analyzed an institutional collection of published papers from 1998 to 2014 authored by researchers from Seoul National University, and their references from papers published between 1998 and 2011. The published papers were collected from Web of Science or Scopus and were analyzed according to the proportion of articles from open access journals. Their cited references from published papers in Web of Science were analyzed according to the proportion of local (South Korean) or open access journals. The proportion of open access papers was relatively stable until 2006 (2.5 ~ 5.2% in Web of Science and 2.7 ~ 4.2% in Scopus), but then increased to 15.9% (Web of Science) or 18.5% (Scopus) in 2014. We analyzed 2,750,485 cited references from 52,295 published papers. We found that the overall proportion of cited articles from local journals was 1.8% and that for open access journals was 3.0%. Citations of open access articles have increased since 2006 to 4.1% in 2011, although the increase in open access article citations was less than for open access publications. The proportion of citations from local journals was even lower. We think that the publishing / citing mismatch is a term to describe this difference, which is an issue at Seoul National University, where the number of published papers at open access or local journals is increasing but the number of citations is not. The cause of this discrepancy is multi-factorial but the governmental / institutional policies, social / cultural issues and authors' citing behaviors will explain the mismatch. However, additional measures are also necessary, such as the development of an institutional citation database and improved search capabilities with respect to local and open access documents.

Rosenkrantz, Andrew B; Ayoola, Abimbola

2016-06-01

The aim of this study was to evaluate the trends in the impact factor (IF) of radiological journals over a recent 12-year period, including associations between IF and journal topic. Journal Citation Reports (JCR) was used to identify all biomedical journals and all radiological journals (assigned a JCR category of "Radiology, Nuclear Medicine, & Medical Imaging"), along with journal IF, in 2003 and 2014. Radiological journals were manually classified by topic. Trends in median IF (mIF) were assessed. The number of radiological journals increased from 83 (2003) to 125 (2014) (all biomedical journals: 5907 to 8718, respectively). mIF of radiological journals increased from 1.42 (2003) to 1.75 (2014) (all biomedical journals: 0.93 to 1.46, respectively). The most common topic among new radiological journals was general (nonspecialized) radiology (8). Five new radiological journals in 2014 were in topics (cancer imaging and molecular imaging) having no journals in 2003. mIF of general radiological journals was 1.49. Topics having highest mIF were cardiac imaging (2.94), optics (2.86), molecular imaging (2.77), radiation oncology (2.60), and neuroradiology (2.25). Topics with lowest mIF were ultrasound (1.19) and interventional radiology (1.44). Topics with the largest increase in mIF were cardiac imaging (from 1.17 to 2.94) and neuroradiology (from 1.07 to 2.25). Radiological journals exhibited higher mIF than biomedical journals overall. Among radiological journals, subspecialty journals had highest mIF. While a considerable number of new radiological journals since 2003 were general radiology journals having relatively low IF, there were also new journal topics representing emerging areas of subspecialized radiological research.

How accurate are quotations and references in medical journals?

PubMed

de Lacey, G; Record, C; Wade, J

1985-09-28

The accuracy of quotations and references in six medical journals published during January 1984 was assessed. The original author was misquoted in 15% of all references, and most of the errors would have misled readers. Errors in citation of references occurred in 24%, of which 8% were major errors--that is, they prevented immediate identification of the source of the reference. Inaccurate quotations and citations are displeasing for the original author, misleading for the reader, and mean that untruths become "accepted fact." Some suggestions for reducing these high levels of inaccuracy are that papers scheduled for publication with errors of citation should be returned to the author and checked completely and a permanent column specifically for misquotations could be inserted into the journal.

The structure of mental health research: networks of influence among psychiatry and clinical psychology journals.

PubMed

Haslam, N; Lusher, D

2011-12-01

Psychiatry and clinical psychology are the two dominant disciplines in mental health research, but the structure of scientific influence and information flow within and between them has never been mapped. Citations among 96 of the highest impact psychiatry and clinical psychology journals were examined, based on 10 052 articles published in 2008. Network analysis explored patterns of influence between journal clusters. Psychiatry journals tended to have greater influence than clinical psychology journals, and their influence was asymmetrical: clinical psychology journals cited psychiatry journals at a much higher rate than the reverse. Eight journal clusters were found, most dominated by a single discipline. Their citation network revealed an influential central cluster of 'core psychiatry' journals that had close affinities with a 'psychopharmacology' cluster. A group of 'core clinical psychology' journals was linked to a 'behavior therapy' cluster but both were subordinate to psychiatry journals. Clinical psychology journals were less integrated than psychiatry journals, and 'health psychology/behavioral medicine' and 'neuropsychology' clusters were relatively peripheral to the network. Scientific publication in the mental health field is largely organized along disciplinary lines, and is to some degree hierarchical, with clinical psychology journals tending to be structurally subordinate to psychiatry journals.

2017-06-01

Using journal metrics, this paper explores whether Annals of Pediatric Endocrinology & Metabolism has internationalized 4 years after changing its language to English only. From the journal's website and the Web of Science Core Collection, the following metrics were counted or calculated: Number of citable articles, countries of authors and editorial board members, total citations, impact factor, countries of citing authors, citing journal titles, and Hirsch index. From 2012 to 2017, 208 articles were citable. The authors had affiliations in 7 countries and the editorial board members in 14 countries. From 2014 to 2017, the total citations each year were 8, 81, 141, and 61; and the impact factors from 2014 to 2016 were calculated as 0.05, 0.987, and 1.165. The citing authors were from 60 countries, among which the United States, China, South Korea, Italy, and Germany were most common. The journal was cited by 215 journal titles. The Hirsch index was 7. These journal metrics showed that the journal achieved international status 4 years after changing the journals' language into English only. The journal's language policy successfully enabled the journal to rebrand as an international journal.

To evaluate the contribution of Turkish scientists to four journals published by Journal of Neurosurgery (JNS) Publishing Group and to Acta Neurochirurgica (AN) and to its Supplement (ANS). We reviewed every issue of those journals to December 2015 for the total number of articles, articles produced from studies performed entirely in Turkey, and for publications overseas co-authored by the Turkish scientists using the websites of these journals. Citations were searched using "Web of Science" and "Google Scholar" databases. The total number of articles published was 19822 for JNS, 3227 for JNS Spine, 2526 for JNS Pediatrics and 2997 for Neurosurgical Focus. Turkish contribution was 556 articles. 337 (60.61%) articles were the products of studies performed entirely in Turkey, while 219 (39.38%) articles came from overseas, co-authored by Turkish scientists. Overall contribution was 1.94%. A total of 6469 articles were published in AN. 340 papers were the products of studies performed entirely in Turkey. Turkish scientists working overseas co-authored 37 articles. Total contribution was 377 articles (5.82%). 4134 papers had been published in ANS. Contribution was 69 articles (1.66%). Turkish contribution to these journals has started late. The gap has been compensated with publications in the last two decades. Manuscripts of higher scientific level with greater number of citations are needed to increase Turkish contribution to such journals.

The retrospective analysis of bibliographical trends for nine biomedical engineering journals from 1999 to 2007.

PubMed

Foo, Jong Yong Abdiel

2009-07-01

For academic research outcomes, there is an increasing emphasis on the bibliometric scorings like the journal impact factor (JIF) when assessment of the quality of research is required. Currently, no known study has been conducted to explore the bibliographical trends of the biomedical engineering journals indexed by the annual Journal Citation Reports of the Thomson Scientific. In this study, the trends of nine reputable journals were selected and analyzed over a 9-year period (year 1999 to year 2007). The results show that the JIF rose exponentially for some journals (up to 597.0%) while for others, it shrank (down to -19.5%). A similar trend is observed for the citations trend over the same period and there was a significant increase in the number of citable articles published (> or =23.6%) in all the selected journals using year 1999 as the base year. However, journals which published significant more non-research articles (> or =10%) saw favorable subsequent effects on their citations. It is postulated that the changes in bibliographical trends can be classified as editorial and non-editorial influences. The retrospective impacts of these influences on the nine selected journals over the 9-year period were also discussed in this study.

The Journal Impact Factor (JIF) is a single citation metric, which is widely employed for ranking journals and choosing target journals, but is also misused as the proxy of the quality of individual articles and academic achievements of authors. This article analyzes Scopus-based publication activity on the JIF and overviews some of the numerous misuses of the JIF, global initiatives to overcome the 'obsession' with impact factors, and emerging strategies to revise the concept of the scholarly impact. The growing number of articles on the JIF, most of which are in English, reflects interest of experts in journal editing and scientometrics toward its uses, misuses, and options to overcome related problems. Solely displaying values of the JIFs on the journal websites is criticized by experts as these average metrics do not reflect skewness of citation distribution of individual articles. Emerging strategies suggest to complement the JIFs with citation plots and alternative metrics, reflecting uses of individual articles in terms of downloads and distribution of related information through social media and networking platforms. It is also proposed to revise the original formula of the JIF calculation and embrace the concept of the impact and importance of individual articles. The latter is largely dependent on ethical soundness of the journal instructions, proper editing and structuring of articles, efforts to promote related information through social media, and endorsements of professional societies.

2016-03-01

We analysed the authorship policies of a random sample of 600 journals from the Journal Citation Reports database. 62.5% of the journals we sampled had an authorship policy. Having an authorship policy was positively associated with impact factor. Journals from the biomedical sciences and social sciences/humanities were more likely to have an authorship policy than journals from the physical sciences, engineering or mathematical sciences. Among journals with a policy, the most frequent type of policy was guidance on criteria for authorship (99.7%); followed by guidance on acknowledgments (97.3%); requiring that authors make substantial contributions to the research (94.7%); requiring that authors be accountable for the research as a whole (84.8%); guidance on changes in authorship (77.9%); requiring that authors give final approval to the manuscript (77.6%); requiring that authors draft or critically revise the manuscript (71.7%); providing guidance on corporate authorship (58.9%); prohibiting gift, guest or ghost authorship (31.7%); requiring authors to describe their contributions (5.3%); limiting the number of authors for some types of articles (4.0%) and requiring authors to be accountable for their part in the research (1.1%). None of the policies addressed equal contribution statements. Journals that do not have authorship policies should consider adopting or developing ones. Published by the BMJ Publishing Group Limited.

Purpose: To evaluate characteristics associated with higher rates of acceptance for original manuscripts submitted for publication to the International Journal of Radiation Oncology • Biology • Physics (IJROBP) and describe the fate of rejected manuscripts. Methods and Materials: Manuscripts submitted to the IJROBP from May 1, 2010, to August 31, 2010, and May 1, 2012, to August 31, 2012, were evaluated for author demographics and acceptance status. A PubMed search was performed for each IJROBP-rejected manuscript to ascertain whether the manuscript was ultimately published elsewhere. The Impact Factor of the accepting journal and the number of citations of the publishedmore » manuscript were also collected. Results: Of the 500 included manuscripts, 172 (34.4%) were accepted and 328 (65.6%) were rejected. There was no significant difference in acceptance rates according to gender or degree of the submitting author, but there were significant differences seen based on the submitting author's country, rank, and h-index. On multivariate analysis, earlier year submitted (P<.0001) and higher author h-index (P=.006) remained significantly associated with acceptance into the IJROBP. Two hundred thirty-five IJROBP-rejected manuscripts (71.7%) were ultimately published in a PubMed-listed journal as of July 2014. There were no significant differences in any submitting author characteristics. Journals accepting IJROBP-rejected manuscripts had a lower median [interquartile range] 2013 impact factor compared with the IJROBP (2.45 [1.53-3.71] vs 4.176). The IJROBP-rejected manuscripts ultimately published elsewhere had a lower median [interquartile range] number of citations (1 [0-4] vs 6 [2-11]; P<.001), which persisted on multivariate analysis. Conclusions: The acceptance rate for manuscripts submitted to the IJROBP is approximately one-third, and approximately 70% of rejected manuscripts are ultimately published in other PubMed-listed journals, but these ultimate

Biomedical research platforms and their influence on article submissions and journal rankings: An update.

2012-01-01

After being indexed in 2006 in EMBASE/Excerpta Medica and Scopus, and later in Science Citation Index Expanded and Journal Citation Reports/Science Edition citation databases, Biochemia Medica launched a new web page and online manuscript submission system in 2010, and celebrated its first Impact Factor in the same year. Now, starting from the end of the 2011, the journal will also be indexed in PubMed/Medline, and this will contribute to increase the journal’s exposure and accessibility worldwide. This is an important breakthrough, which is expected to further increase the popularity of the journal, as well as the submission rate and citations. Although several tools are currently available as Web resources to retrieve scientific articles, whose functioning and basic criteria are thought to be rather similar, the functionality, coverage, notoriety and prominence may differ widely. The recent indexing of Biochemia Medica in PubMed/Medline has thereby given us the opportunity to provide a timely update on biomedical research platforms, their relationship with article submissions and journal rankings.

Huh, Sun

2015-07-01

This study aims to verify the internationalization of Clinical Endoscopy based on journal metrics after the change to English-only in 2011. The results of this study serve as a starting point for developing strategies to develop Clinical Endoscopy into a top-tier international journal. The following journal metrics were analyzed from the journal's homepage or the Web of Science: the number of citable articles, number of countries of affiliation of the contributors, the number of articles supported by research grants, total citations, impact factor, citing journals, countries of citing authors, and the Hirsch index. The number of citable articles in 2011, 2012, 2013, and 2014 was 22, 81, 120, and 95, respectively. The authors were from 11 countries. Twenty-one out of 55 original articles were supported by research grants. The total citations in 2012, 2013, and 2014 were 2, 85, and 213, respectively. The impact factor was 0.670 in 2013 and 0.940 in 2014. The number of countries citing authors were from was 61. The Hirsch index was 6. The above results demonstrate that Clinical Endoscopy became an international journal, contributing to the propagation of valuable research results through an open access publishing model.

Prospective registration of randomized controlled trials (RCTs) represents the best solution to reporting bias. The extent to which oral health journals have endorsed and complied with RCT registration is unknown. We identified journals publishing RCTs in dentistry, oral surgery, and medicine in the Journal Citation Reports. We classified journals into 3 groups: journals requiring or recommending trial registration, journals referring indirectly to registration, and journals providing no reference to registration. For the 5 journals with the highest 2012 impact factors in each group, we assessed whether RCTs with results published in 2013 had been registered. Of 78 journals examined, 32 (41%) required or recommended trial registration, 19 (24%) referred indirectly to registration, and 27 (35%) provided no reference to registration. We identified 317 RCTs with results published in the 15 selected journals in 2013. Overall, 73 (23%) were registered in a trial registry. Among those, 91% were registered retrospectively and 32% did not report trial registration in the published article. The proportion of trials registered was not significantly associated with editorial policies: 29% with results in journals that required or recommended registration, 15% in those that referred indirectly to registration, and 21% in those providing no reference to registration (P = 0.05). Less than one-quarter of RCTs with results published in a sample of oral health journals were registered with a public registry. Improvements are needed with respect to how journals inform and require their authors to register their trials. © International & American Associations for Dental Research.

2017-07-01

Emerging alternative metrics leverage social media and other online platforms to provide immediate measures of biomedical articles' reach among diverse public audiences. We aimed to compare traditional citation and alternative impact metrics for articles in popular general radiology journals. All 892 original investigations published in 2013 issues of Academic Radiology, American Journal of Roentgenology, Journal of the American College of Radiology, and Radiology were included. Each article's content was classified as imaging vs nonimaging. Traditional journal citations to articles were obtained from Web of Science. Each article's Altmetric Attention Score (Altmetric), representing weighted mentions across a variety of online platforms, was obtained from Altmetric.com. Statistical assessment included the McNemar test, the Mann-Whitney test, and the Pearson correlation. Mean and median traditional citation counts were 10.7 ± 15.4 and 5 vs 3.3 ± 13.3 and 0 for Altmetric. Among all articles, 96.4% had ≥1 traditional citation vs 41.8% for Altmetric (P < 0.001). Online platforms for which at least 5% of the articles were represented included Mendeley (42.8%), Twitter (34.2%), Facebook (10.7%), and news outlets (8.4%). Citations and Altmetric were weakly correlated (r = 0.20), with only a 25.0% overlap in terms of articles within their top 10th percentiles. Traditional citations were higher for articles with imaging vs nonimaging content (11.5 ± 16.2 vs 6.9 ± 9.8, P < 0.001), but Altmetric scores were higher in articles with nonimaging content (5.1 ± 11.1 vs 2.8 ± 13.7, P = 0.006). Although overall online attention to radiology journal content was low, alternative metrics exhibited unique trends, particularly for nonclinical articles, and may provide a complementary measure of radiology research impact compared to traditional citation counts.

To analyze the trends and developments among journals in the specialty of obstetrics and gynecology. Using the Journal Citation Reports from 2007 to 2013, we analyzed the impact factor (IF), Eigenfactor® Score (ES), and Article Influence® Score (AIS) of 43 journals in the field of obstetrics and gynecology published in this time period. From 78 journals of the Journal Citation Report 2013, 43 were selected for this study. The mean IF grew from 1.68 ± 0.97 in 2007 to 2.12 ± 1.05 in 2013, the ES from 0.0113 ± 0.0169 to 0.0114 ± 0.0140, and the AIS from 0.513 ± 0.302 to 0.663 ± 0.359. Differences in the IF, ES, and AIS between journals from the United States versus Europe could be observed. In most cases, the IF, ES, and AIS increased between 2007 and 2013. Strong correlations could be found between IF, AIS, and ES. The overall mean IF for obstetrical and gynecological journals increased over the analyzed time period. The IF remains the standard measure to compare scientific journals. It correlates well with two major alternative measures of scientific impact, the ES and especially the AIS. Other measures are evolving and might show superior usage in the future.

Objectives: To compare the journal impact factor (JIF) and Eigenfactor score (ES) of Institute for Scientific Information (ISI)-indexed biomedical journals published from the Kingdom of Saudi Arabia (KSA) over the last 8 years. Methods: This is a retrospective study, conducted at Alfaisal University, Riyadh, KSA from January to March 2016. The Journal Citation Reports of ISI Web of Knowledge were accessed, and 6 Saudi biomedical journals were included for analysis. Results: All Saudi journals have improved their IF compared with their baseline. However, the performance of the Journal of Pharmaceutical Sciences and Neurosciences has been exceptionally good. The biggest improvement in percent growth in JIF was seen in the Saudi Pharmaceutical Journal (approximately 887%) followed by Neurosciences (approximately 462%). Interestingly, the ES of all biomedical journals, except Saudi Journal of Gastroenterology and Saudi Medical Journal, increased over the years. The greatest growth in ES (more than 5 fold) was noted for Neurosciences and Saudi Pharmaceutical Journal. Conclusion: This study shows that the overall quality of all Saudi biomedical journals has improved in the last 8 years. PMID:27761565

The Journal of Child Neurology (JCN) began in 1986 as a quarterly publication focused on child neurology and the related clinical pediatric neuroscience areas of pediatric neurosurgery, child psychiatry, pediatric neuroradiology, and developmental and behavioral pediatrics. As submitted material increased, JCN expanded in publication frequency and now appears monthly. Article quality has always been high and many articles have been frequently cited. Over the years, the ratings produced for the ISI Journal Citation Reports have identified JCN as a high-ranking pediatric journal based upon the impact factor value. Currently (year 2002 figures), JCN (with its impact factor of 1.338) ranks 24th out of 68 pediatric journals.

The objective of this study is to analyse the citation patterns and impact and immediacy indicators of the Farmacia Hospitalaria journal during the period 2001-2005. An analysis of citations chosen from 101 Spanish health science journals was carried out in order to determine the citing and cited journals and the national and international impact and immediacy indicators. A similar methodology used by Thomson ISI in Science Citation Index (SCI) and Journal Citation Reports (JRC) was applied. Farmacia Hospitalaria made 1,370 citations to 316 different journals. The percentage of self-citations was 9%. The national impact factor increased from 0.178 points in 2001 to 0.663 points in 2005 while the international impact factor increased from 0.178 to 0.806 for the same period. The analysis of citation patterns demonstrates the multidisciplinary nature of Farmacia Hospitalaria and a significant growth in the impact indicators over recent years. These indicators are higher than those of some other pharmacy journals included in Journal Citation Reports. Self-citation was not excessive and was similar to that of other journals.

The purpose of this study was to identify the clinical pediatric orthopaedic articles with at least 100 citations published in all orthopaedic journals and to examine their characteristics. All journals dedicated to orthopaedics and its subspecialties were selected from the Journal Citation Report 2001 under the subject category "orthopedics." Articles cited 100 times or more were identified using the database of the Science Citation Index Expanded (SCI-EXPANDED, 1900 to present). The articles were ranked in a comprehensive list. Two authors independently reviewed the full text of each article and applied the inclusion and exclusion criteria to the list of articles. The 2 lists were then compared. All disagreements were resolved by consensus with input from the senior author. The final list of pediatric orthopaedic articles was then compiled. There were a total of 49 journals under the search category "orthopedics." Five journals were excluded as they were non-English journals. The remaining 44 journals were screened for articles with at least 100 citations. A total of 135 clinical pediatric orthopaedic articles cited at least 100 times were included. The most cited article was cited 692 times. The mean number of citations per article was 159 (95% confidence interval, 145-173). All the articles were published between 1949 and 2001, with 1980 and 1989 producing the most citation classics (34). The majority (90) originated from the United States, followed by the United Kingdom (12) and Canada (11). Scoliosis/kyphosis was the most common topic with 26 papers. The second most common subject was hip disorders (24). Therapeutic studies were the most common study type (71). Ninety-seven papers were assigned a 4 for level of evidence. The list of citation classics in pediatric orthopaedic articles is useful for several reasons. It identifies important contributions to the field of pediatric orthopaedics and their originators; it facilitates the understanding and discourse

To examine indexed health science journals to evaluate the prevalence of Wikipedia citations, identify the journals that publish articles with Wikipedia citations, and determine how Wikipedia is being cited. Bibliometric analysis. Publications in the English language that included citations to Wikipedia were retrieved using the online databases Scopus and Web of Science. To identify health science journals, results were refined using Ulrich's database, selecting for citations from journals indexed in Medline, PubMed, or Embase. Using Thomson Reuters Journal Citation Reports, 2011 impact factors were collected for all journals included in the search. Resulting citations were thematically coded, and descriptive statistics were calculated. 1433 full text articles from 1008 journals indexed in Medline, PubMed, or Embase with 2049 Wikipedia citations were accessed. The frequency of Wikipedia citations has increased over time; most citations occurred after December 2010. More than half of the citations were coded as definitions (n = 648; 31.6%) or descriptions (n=482; 23.5%). Citations were not limited to journals with a low or no impact factor; the search found Wikipedia citations in many journals with high impact factors. Many publications are citing information from a tertiary source that can be edited by anyone, although permanent, evidence based sources are available. We encourage journal editors and reviewers to use caution when publishing articles that cite Wikipedia.

The Journal Impact Factor: Moving Toward an Alternative and Combined Scientometric Approach

PubMed Central

Nurmashev, Bekaidar

2017-01-01

The Journal Impact Factor (JIF) is a single citation metric, which is widely employed for ranking journals and choosing target journals, but is also misused as the proxy of the quality of individual articles and academic achievements of authors. This article analyzes Scopus-based publication activity on the JIF and overviews some of the numerous misuses of the JIF, global initiatives to overcome the ‘obsession’ with impact factors, and emerging strategies to revise the concept of the scholarly impact. The growing number of articles on the JIF, most of which are in English, reflects interest of experts in journal editing and scientometrics toward its uses, misuses, and options to overcome related problems. Solely displaying values of the JIFs on the journal websites is criticized by experts as these average metrics do not reflect skewness of citation distribution of individual articles. Emerging strategies suggest to complement the JIFs with citation plots and alternative metrics, reflecting uses of individual articles in terms of downloads and distribution of related information through social media and networking platforms. It is also proposed to revise the original formula of the JIF calculation and embrace the concept of the impact and importance of individual articles. The latter is largely dependent on ethical soundness of the journal instructions, proper editing and structuring of articles, efforts to promote related information through social media, and endorsements of professional societies.

Impact factor and other indices to assess science, scientists and scientific journals.

Satyanarayana, K

2010-01-01

This paper traces the evolution of measures and parameters for the evaluation of science and scientific journals from the first attempts during the early part of the last century to the development of the most popular, current and widely used metrics viz., citations, impact factor (IF) etc. The identification of measures of evaluation in science and scientific reporting paralled the post-war increase in funding in the United States of America. Biomedical and medical sciences continue to garner a major share, estimated to be almost two-thirds of total research and development funding of over US$ 350 billion. There has been a concomitant growth in the publications in learned journals. About 1.4 million papers are published every year in an estimated 20,000 journals. In India there are an estimated 100 journals in medical sciences. With a steady increase of about 10% every year, the competition for grants, awards, rewards etc., is fierce. This unrelenting increase in number of scientists and the resultant competition, the limitation of peer review was felt. A search was on for new quantifiable measures for informed decision making for funding, awards, rewards, etc. Now virtually all major decisions all over the world are based on some data linked to publications and/or citations. The concept of citations as tool for 'evaluating' science was first proposed by Eugene Garfield in 1955. The availability of Science Citation Index (SCI), Journal Citation Reports (JCR), Web of Science etc. and the relative ease with which they could be used (and abused) has spawned an entirely new area bibliometrics/scientometrics. As only a limited number of journals could be included in the Thomson Reuters (TR) databases (currently numbering about 10500), analyses based on such a limited dataset (also selected in a non-transparent way by the TR) has been widely and severely criticized by both the developed and developing countries. Yet, studies have shown that citation-based data and

Effects of Print Publication Lag in Dual Format Journals on Scientometric Indicators

PubMed Central

Heneberg, Petr

2013-01-01

Background Publication lag between manuscript submission and its final publication is considered as an important factor affecting the decision to submit, the timeliness of presented data, and the scientometric measures of the particular journal. Dual-format peer-reviewed journals (publishing both print and online editions of their content) adopted a broadly accepted strategy to shorten the publication lag: to publish the accepted manuscripts online ahead of their print editions, which may follow days, but also years later. Effects of this widespread habit on the immediacy index (average number of times an article is cited in the year it is published) calculation were never analyzed. Methodology/Principal Findings Scopus database (which contains nearly up-to-date documents in press, but does not reveal citations by these documents until they are finalized) was searched for the journals with the highest total counts of articles in press, or highest counts of articles in press appearing online in 2010–2011. Number of citations received by the articles in press available online was found to be nearly equal to citations received within the year when the document was assigned to a journal issue. Thus, online publication of in press articles affects severely the calculation of immediacy index of their source titles, and disadvantages online-only and print-only journals when evaluating them according to the immediacy index and probably also according to the impact factor and similar measures. Conclusions/Significance Caution should be taken when evaluating dual-format journals supporting long publication lag. Further research should answer the question, on whether the immediacy index should be replaced by an indicator based on the date of first publication (online or in print, whichever comes first) to eliminate the problems analyzed in this report. Information value of immediacy index is further questioned by very high ratio of authors’ self-citations among the

Impact Factors and Prediction of Popular Topics in a Journal.

PubMed

Nielsen, M B; Seitz, K

2016-08-01

The impact factor (IF) for 2015 was recently released and this could be the time to once again reflect on its use as a metric of a journal. Problems and concerns regarding the IF have been addressed extensively elsewhere 1 2. The principle of the IF for a given year is that it represents the average number of citations of articles published in the journal in the two previous years.While authors frequently cite the IF as a determining factor for submission, the IF does not predict how many times individual articles will be cited. In a study from a peer-reviewed cardiovascular journal, nearly half of all published articles were poorly cited, i. e., less than five citations in five years 3. A similar percentage seems to apply to our journal. In nearly all journals we estimate that the majority of citations relate to a minority of the articles. Some articles are never cited. 13 % of the articles published in our journal from 2010 to 2013 have never been cited. Even authors of poorly cited articles benefit from the IF since many institutions use the combined impact factors of their published papers to measure research activity and this may be reflected in their research budgets.The competition for the printed pages in the six annual issues of Ultraschall in der Medizin/European Journal of Ultrasound (UiM/EJU) has resulted in high rejection rates (between 80 % and 90 %). One negative review with recommendation of major revision may therefore result in rejection. Peer-review fraud where the submitting author listed recommended reviewers with fake email addresses supplying fabricated peer reviews has recently been described in the New England Journal of Medicine 4. Some of the editors of our journal believe they have experienced this as well. Fabricating reviews in order to get a high IF for an article is to be considered fraud and is inexcusable.One aspect of using impact factors as a measure of the quality of a journal is that the IF only goes back two years

Relationship between Quality and Editorial Leadership of Biomedical Research Journals: A Comparative Study of Italian and UK Journals

Matarese, Valerie

2008-01-01

Background The quality of biomedical reporting is guided by statements of several organizations. Although not all journals adhere to these guidelines, those that do demonstrate “editorial leadership” in their author community. To investigate a possible relationship between editorial leadership and journal quality, research journals from two European countries, one Anglophone and one non-Anglophone, were studied and compared. Quality was measured on a panel of bibliometric parameters while editorial leadership was evaluated from journals' instructions to authors. Methodology/Principal Findings The study considered all 76 Italian journals indexed in Medline and 76 randomly chosen UK journals; only journals both edited and published in these countries were studied. Compared to UK journals, Italian journals published fewer papers (median, 60 vs. 93; p = 0.006), less often had online archives (43 vs. 74; p<0.001) and had lower median values of impact factor (1.2 vs. 2.7, p<0.001) and SCImago journal rank (0.09 vs. 0.25, p<0.001). Regarding editorial leadership, Italian journals less frequently required manuscripts to specify competing interests (p<0.001), authors' contributions (p = 0.005), funding (p<0.001), informed consent (p<0.001), ethics committee review (p<0.001). No Italian journal adhered to COPE or the CONSORT and QUOROM statements nor required clinical trial registration, while these characteristics were observed in 15%–43% of UK journals (p<0.001). At multiple regression, editorial leadership predicted 37.1%–49.9% of the variance in journal quality defined by citation statistics (p<0.0001); confounding variables inherent to a cross-cultural comparison had a relatively small contribution, explaining an additional 6.2%–13.8% of the variance. Conclusions/Significance Journals from Italy scored worse for quality and editorial leadership than did their UK counterparts. Editorial leadership predicted quality for the entire set of journals

2017-05-01

To evaluate the impact of publications on urological participation in social media (SoMe) by virtue of citations in the urological and non-urological literature. On 15 March 2016, a PubMed search was undertaken using the names of the major SoMe platforms in current use and associated with the field of urology. The search term 'urolog*' was used to specifically capture articles that could be associated with 'urology', 'urologist' or 'urological'. Exclusion criteria for analysis included non-English language articles, articles published for the first time online in any form after 1 March 2015, articles irrelevant to the topic of SoMe, and letters of correspondence. Included articles were then searched in Google Scholar and citations analysed to determine if citations were from the urological literature or non-urological literature. Citations from non-urological journals were considered to be as such even if authored by urologists and on the subject of urology and SoMe. Prior to exclusions as defined in the methods, our PubMed search yielded 232 articles of which 17 were non-English language and 66 had been published after 1 March 2015. Allowing for 12 months after the most recent articles were published, we found that the mean number of total citations in any journal was 20.8. There were more citations in journals not specific to urology, with 8.3 citations in urological journals, compared to 12.6 citations in non-urological journals. Urological SoMe journal articles are highly cited, particularly in the non-urological literature. It is likely that the magnitude of citations has positively contributed to the impact factors of the almost all journals publishing these manuscripts. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

2015-01-01

Background/Aims This study aims to verify the internationalization of Clinical Endoscopy based on journal metrics after the change to English-only in 2011. The results of this study serve as a starting point for developing strategies to develop Clinical Endoscopy into a top-tier international journal. Methods The following journal metrics were analyzed from the journal's homepage or the Web of Science: the number of citable articles, number of countries of affiliation of the contributors, the number of articles supported by research grants, total citations, impact factor, citing journals, countries of citing authors, and the Hirsch index. Results The number of citable articles in 2011, 2012, 2013, and 2014 was 22, 81, 120, and 95, respectively. The authors were from 11 countries. Twenty-one out of 55 original articles were supported by research grants. The total citations in 2012, 2013, and 2014 were 2, 85, and 213, respectively. The impact factor was 0.670 in 2013 and 0.940 in 2014. The number of countries citing authors were from was 61. The Hirsch index was 6. Conclusions The above results demonstrate that Clinical Endoscopy became an international journal, contributing to the propagation of valuable research results through an open access publishing model.

To analyze the aggregate impact factor (AIF) in ophthalmology, its inflation rate, and its relation to other subject fields. A retrospective, database review of all subject fields in the Journal Citation Reports (JCR), Science edition. Citation data, AIF, number of journals and citations from the years 2003-2011 were analyzed. Data were retrieved from JCR. Future trends were calculated using a linear regression method. The AIF varies considerably between subjects. It shows also an inflation rate, which varies annually. The AIF inflation rate in ophthalmology was not as high as the background AIF inflation rate. The AIF inflation rate caused the AIF to increase annually. Not considering these variations in the AIF between years and between fields will make the AIF as a bibliometric tool inappropriate.

2010-06-01

AGU publishes great science, which is recognized in several ways. One of the most widely recognized is from Thomson Reuters, which provides the Journal Citation Report (JCR) each year as a component of the Web of Science®. JCR reports on several measures of journal usage, including a journal's Eigenfactor score, its Article Influence score, its Impact Factor, and its rank within a cohort of similar journals. According to the 2009 statistics released last week, AGU again has outperformed its larger competitors. For the twelfth time, two different AGU titles hold the top rank in their categories, and AGU titles hold the second spot in two other categories and third in two more.

2011-01-01

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. PMID:21753912

The relationship between traditional metrics of research impact (e.g., number of citations) and alternative metrics (altmetrics) such as Twitter activity are of great interest, but remain imprecisely quantified. We used generalized linear mixed modeling to estimate the relative effects of Twitter activity, journal impact factor, and time since publication on Web of Science citation rates of 1,599 primary research articles from 20 ecology journals published from 2012–2014. We found a strong positive relationship between Twitter activity (i.e., the number of unique tweets about an article) and number of citations. Twitter activity was a more important predictor of citation rates than 5-year journal impact factor. Moreover, Twitter activity was not driven by journal impact factor; the ‘highest-impact’ journals were not necessarily the most discussed online. The effect of Twitter activity was only about a fifth as strong as time since publication; accounting for this confounding factor was critical for estimating the true effects of Twitter use. Articles in impactful journals can become heavily cited, but articles in journals with lower impact factors can generate considerable Twitter activity and also become heavily cited. Authors may benefit from establishing a strong social media presence, but should not expect research to become highly cited solely through social media promotion. Our research demonstrates that altmetrics and traditional metrics can be closely related, but not identical. We suggest that both altmetrics and traditional citation rates can be useful metrics of research impact.

Background It is not clear which research misconduct policies are adopted by biomedical journals. This study assessed the prevalence and content policies of the most influential biomedical journals on misconduct and procedures for handling and responding to allegations of misconduct. Methods We conducted a cross-sectional study of misconduct policies of 399 high-impact biomedical journals in 27 biomedical categories of the Journal Citation Reports in December 2011. Journal websites were reviewed for information relevant to misconduct policies. Results Of 399 journals, 140 (35.1%) provided explicit definitions of misconduct. Falsification was explicitly mentioned by 113 (28.3%) journals, fabrication by 104 (26.1%), plagiarism by 224 (56.1%), duplication by 242 (60.7%) and image manipulation by 154 (38.6%). Procedures for responding to misconduct were described in 179 (44.9%) websites, including retraction, (30.8%) and expression of concern (16.3%). Plagiarism-checking services were used by 112 (28.1%) journals. The prevalences of all types of misconduct policies were higher in journals that endorsed any policy from editors’ associations, Office of Research Integrity or professional societies compared to those that did not state adherence to these policy-producing bodies. Elsevier and Wiley-Blackwell had the most journals included (22.6% and 14.8%, respectively), with Wiley journals having greater a prevalence of misconduct definition and policies on falsification, fabrication and expression of concern and Elsevier of plagiarism-checking services. Conclusions Only a third of top-ranking peer-reviewed journals had publicly-available definitions of misconduct and less than a half described procedures for handling allegations of misconduct. As endorsement of international policies from policy-producing bodies was positively associated with implementation of policies and procedures, journals and their publishers should standardize their policies globally in order to

There has been an increasing focus on academic productivity for the purposes of promotion and funding within departments and institutions but also for comparison of individuals, institutions, specialties, and journals. A number of quantitative indices are used to investigate and compare academic productivity. These include various calculations attempting to analyze the number and citations of publications in order to capture both the quality and quantity of publications, such as the h index, the e index, impact factor, and Eigenfactor score. The indices have varying advantages and limitations and thus a basic knowledge is required in order to understand their potential utility within academic medicine. This article describes the various bibliometric indices and discusses recent applications of these metrics within the neurological sciences. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Arciniega, L T; Miller, W R

1997-12-01

A search and survey of specialty periodicals in the addiction field identified 35 English-language scientific journals that publish unsolicited research manuscripts. Among these, the typical addiction journal publishes a variety of types of articles in one of many different citation and referencing formats, releases four issues per year to about 1000 subscribers, annually receives more than 100 manuscripts for scientific review, and accepts 53 of them to be published without payment of an author fee. Together these 35 addiction journals publish over 1700 new articles each year. Addiction journals vary widely in acceptance rates, ranging from 26% to 95%, and averaging 53%. For better or worse, these journals offer ample opportunity for the reporting of scientific data in the addiction field.

Publications in anesthesia journals: quality and clinical relevance.

Clinicians performing evidence-based anesthesia rely on anesthesia journals for clinically relevant information. The objective of this study was to analyze the proportion of clinically relevant articles in five high impact anesthesia journals. We evaluated all articles published in Anesthesiology, Anesthesia & Analgesia, British Journal of Anesthesia, Anesthesia, and Acta Anaesthesiologica Scandinavica from January to June, 2000. Articles were assessed and classified according to type, outcome, and design; 1379 articles consisting of 5468 pages were evaluated and categorized. The most common types of article were animal and laboratory research (31.2%) and randomized clinical trial (20.4%). A clinically relevant article was defined as an article that used a statistically valid method and had a clinically relevant end-point. Altogether 18.6% of the pages had as their subject matter clinically relevant trials. We compared the Journal Impact Factor (a measure of the number of citations per article in a journal) and the proportion of clinically relevant pages and found that they were inversely proportional to each other.

AGU journals continue to rank highly in the 2011 Journal Citation Reports (JCR), which was released by Thomson Reuters on 28 June. The impact factor of several AGU journals increased significantly, continuing their trend over the previous 5 years, while others remained consistent with the previous year's ranking. Paleoceanography is an outstanding performer in both the Paleontology and Oceanography categories. Since 1995, Paleoceanography has been the top-ranked journal in the Paleontology category (of 49 titles in 2011), with an Impact Factor of 3.357. In the Oceanography group (59 journals total), Paleoceanography ranks third in Impact Factor. Reviews of Geophysics, with an Impact Factor of 12.364 (an increase of 2.826 from the prior year's score of 9.538), ranks second in Geochemistry and Geophysics out of a total of 77 journals in this cohort. Water Resources Research comes in at second place in the Limnology group, with 19 titles, and third place in the Water Resources group, which has a cohort of 78 titles.

Essentials Reporting guidelines and trial/review registration aim to limit bias in research. We systematically reviewed hematology journals to examine the use of these policies. Forty-eight percent of journals made no use of these policies. Improving the use of reporting guidelines will improve research for all stakeholders. Background Reporting guidelines and trial/review registration policies have been instituted in order to minimize bias and improve research practices. Objective The objective of this study was to investigate the policies of hematology journals concerning reporting guideline adoption and trial/review registration. Methods We performed a web-based data abstraction from the Instructions for Authors of 67 hematology journals catalogued in the Expanded Science Citation Index of the 2014 Journal Citation Reports to identify whether each journal required, recommended or made no mention of the following reporting guidelines: EQUATOR, ICMJE, CONSORT, MOOSE, QUOROM, PRISMA, STARD, STROBE, ARRIVE and CARE. We also extracted whether journals required or recommended trial or systematic review registration. We e-mailed editors three times to determine which types of studies their journal accepts. Results Forty-eight per cent (32/67) of hematology journals do not adhere to any reporting guidelines. For responding journals, the QUOROM statement, MOOSE, CARE and PROSPERO were the least often mentioned, whereas the ICMJE guidelines, CONSORT statement and general trial registration were most often mentioned. Discussion Reporting guidelines are infrequently required or recommended by hematology journals. Furthermore, few require clinical trial or systematic review database registration. A higher rate of adherence to reporting guidelines can prevent bias from entering the literature. Participation from all stakeholders, including authors and journal editors, to improve reporting guideline and policy practices is required. © 2017 International Society on Thrombosis

Cardona, Genís; Sanz, Joan P

2014-09-01

This study aimed at exploring the citation parameters of contact lenses articles published in the Ophthalmology thematic category of the Journal Citation Reports (JCR). The Thompson Reuters Web of Science database was accessed to record bibliometric information and citation parameters of all journals listed under the Ophthalmology area of the 2011 JCR edition, including the journals with main publication interests in the contact lens field. In addition, the same database was used to unveil all contact lens-related articles published in 2011 in the same thematic area, whereupon differences in citation parameters between those articles published in contact lens and non-contact lens-related journals were explored. Significant differences in some bibliometric indicators such as half-life and overall citation count were found between contact lens-related journals (shorter half-life and fewer citations) and the median values for the Ophthalmology thematic area of the JCR. Visual examination of all Ophthalmology journals uncovered a total of 156 contact lens-related articles, published in 28 different journals, with 27 articles each for Contact Lens & Anterior Eye, Eye & Contact Lens, and Optometry and Vision Science. Significant differences in citation parameters were encountered between those articles published in contact lens and non-contact lens source journals. These findings, which disclosed contact lenses to be a fertile area of research, may be of interest to researchers and institutions. Differences in bibliometric indicators are of relevance to avoid unwanted bias when conducting between- and within-discipline comparisons of articles, journals, and researchers.

AIM: To understand the changes and development of World Journal of Gastroenterology (WJG) in recent years. METHODS: The Journal Citation Report (JCR) and SCI-E database of the ISI Web of Knowledge were used to search the articles and data of related indices in WJG during 2008-2012. Bibliometric methods were used for statistical analysis of the author’s degree of collaboration, collaboration rate, the first author’s publications, high-productivity authors, the authors’ origins in each year; the distribution of the countries and journals of the authors citing WJG papers was also analyzed. In addition, the indices related to this journal in each year were compared with the data from 6 SCI journals in the field of gastroenterology in the 2012 volume. RESULTS: A total of 4409 papers in WJG were examined in this study. For the period 2008-2012, the self-citation rate was 8.59%, 6.02%, 5.50%, 4.47% and 5.21%. Of a total of 3898 first authors, 3526 published 1 paper, 291 published 2 papers, 59 published 3 papers, and 22 published 4 or more papers. The origin of WJG authors covered the six continents, and the majority came from Asia, Europe and North America. The number of countries of origin of WJG authors was 65, 66, 61, 65 an 60 for the period 2008-2012. Authors from 66 countries cited a total of 3194 of the 4409 papers, and these citations were found in 1140 journals. CONCLUSION: The results suggest that WJG has stayed on the track of normal international publication and all the indices of this journal are stable and reasonable. PMID:24307776

To identify 100 top-cited articles published in periodontal journals and analyse the research trends by using citation analysis. 100 top-cited articles published in periodontal journals were retrieved by searching the database of the ISI Web of Science and Journal Citation reports. For each article, the following principal bibliometric parameters: authorship, geographic and institute origin, manuscript type, study design, scope of study, and citation count of each time period were analysed from 1965 to 2015. The identified 100 top-cited articles were retrieved from five periodontal journals and citation counts were recorded between 262 and 1,693 times. For the institute of origin, the most productive institute, in terms of the number of 100 top-cited articles published, was the University of Gothenburg (Sweden) (n = 19), followed by the Forsyth Dental Center (USA) (n = 15). Most manuscripts were original research (n = 74), and the inflammatory periodontal disease (n = 59) was the most frequent topic studied. Interestingly, the trend of increase average citation reached significance for implantology (β = 26.75, P = 0.003) and systemic interactions (β = 29.83, P = 0.005), but not for inflammatory disease (β = -10.30, P = 0.248) and tissue regeneration (β = 9.04, P = 0.081). By using multivariable linear regression in a generalised linear model, suitable published journal (Journal of Clinical Periodontology), geographic regions (Europe), more intense international collaboration, adequate manuscript type (review article) and study design (systematic review) could be attributed to escalating average citation counts in implantology (all P < 0.05). However, for systemic interactions, only geographic region and study design were significantly associated with the increasing citation trend. These principal bibliometric characteristics revealed escalated trends in average citation count in implantology throughout time. Conflict-of-interest statement The authors have

Publication speed of peer-reviewed journals may play a major role in early dissemination of knowledge and may raise the citation index. In this study, we evaluated the publication speed of ophthalmology journals. Observational study. Observational study of bibliometric data in published ophthalmology journals. A list of ophthalmic journals featured in the 2010 Journal Citation Report was obtained on September 1, 2011. A total of 12 articles were chosen randomly from each of these journals published between January and December 2010. Median publication time and interquartile range (IQR) were obtained from the full texts of the published articles. Time lag between submission and revision, acceptance, and publication of the manuscripts was calculated. Correlation between publication time lag and journal impact factor as well as advance online publication was analyzed. A total of 51 ophthalmic journals were included. There was no statistically significant difference in the impact factors of journals based on their reporting of submission, revision, or acceptance times of the manuscripts (both P>0.05, Wilcoxon test). The median peer review and publication time of all ophthalmology journals was 133 days (IQR, 100.5-171.5) and 100 days (IQR, 62.9-166.3), respectively. There was no correlation between the journal impact factors and publication time lag (Spearman correlation). Approximately half of the ophthalmology journals (n = 26; 50.98%) published online in advance. Journals with advance online publication had higher impact factors compared with those without this feature (median, 1.692 [IQR, 1.05-2.80] vs. 1.02 [0.39-1.53]; P = 0.015, Mann-Whitney U test). For journals with advance online publication, the median time from acceptance to advance online publication (74.3 days [IQR, 48.3-115 days]) was significantly shorter than the median time between acceptance and print publication (170.75 days [IQR, 101.4-217 days]; P<0.001, Wilcoxon test).

The obligation to publish academic papers in order to get academic rank has made medical doctors more ambitious to publish faster and more papers. According to the ethical and legal rules in our country and in the world, if an idea or technical methods of another person is used in a medical journal, the owner of the method or idea and its publication has to be cited. If an idea, information or a technical method of another scientist is published without citation as if it was one's own idea it's called "Plagiarism". Despite the prohibitive laws and rules, this scientific stealing has become an increasing problem for medical journals worldwide.

Citations published in online supplementary material (OSM) are invisible to search engines used to calculate citation counts, potentially negatively impacting popular performance indices and journal rankings that rely on citation counts for quantification. To quantify the number of citations that are “lost” in OSM, we conducted a systematic survey of supplementary citation practices in four high-ranking, society-run journals from two geographical locations (Europe and North America). In 2012, 6% of all citations were only included in the OSM and were therefore not included in citation counts. We found a significant increase in the number of references invisible to citation counting services over the last two decades. A solution to this problem is urgently required and could include journal indexing of citations in OSM or the inclusion of all references in the main text. PMID:25628876

This study aimed to investigate the current status and policy of Conflict of interest (COI) reporting in biomedical journals in China. Thirty Chinese-language medical journals and 37 English-language biomedical journals indexed by Journal Citation Reports categories were included into this study. These 67 journals were all published in China. All articles published in the most recent two issues were checked for identifying the disclosure statement in the text or not. Twenty-one of 30 (70%) Chinese-language journals required a disclosure of author's potential COI. No journals require editors or referees to disclose the conflicts of interest to the readers. In total, 1,212 publications in Chinese-language were evaluated. Only two journals reported COI in their publications. For the 37 English-language journals, 32 (86.5%) required author's potential COI disclosure, and four of them required only research articles or original articles to disclose COI. A total of 1,170 publications were evaluated. Among them, 50% editorials, 79.3% review articles, and 73.6% original articles reported presence or absence of COI. In our studied journals, the percentage of the policies requiring author COI disclosure is still low. Biomedical journals published in China should enforce COI disclosure policies to authors, editors, and referees.

Journal based metrics is known not to be ideal for the measurement of the quality of individual researcher's scientific output. In the current report 16 contributors from Hong Kong SAR, India, Korea, Taiwan, Russia, Germany, Japan, Turkey, Belgium, France, Italy, UK, The Netherlands, Malaysia, and USA are invited. The following six questions were asked: (I) is Web of Sciences journal impact factor (IF) and Institute for Scientific Information (ISI) citation the main academic output performance evaluation tool in your institution? and your country? (II) How does Google citation count in your institution? and your country? (III) If paper is published in a non-SCI journal but it is included in PubMed and searchable by Google scholar, how it is valued when compared with a paper published in a journal with an IF? (IV) Do you value to publish a piece of your work in a non-SCI journal as much as a paper published in a journal with an IF? (V) What is your personal view on the metric measurement of scientific output? (VI) Overall, do you think Web of Sciences journal IF is beneficial, or actually it is doing more harm? The results show that IF and ISI citation is heavily affecting the academic life in most of the institutions. Google citation and evaluation, while is being used and convenient and speedy, has not gain wide 'official' recognition as a tool for scientific output evaluation.

Journal ranking based on the impact factor (IF) can be distorted by self-citation. The aim of this study is to investigate the present status of self-citation in the plastic surgery journals and its effect on the journals' IFs. IF, IF without self-citations (corrected IF), self-cited rate, and self-citing rate for 11 plastic surgery journals were investigated from 2009-2015, by reviewing the Journal Citation Report ® . The correlations of the IF with the self-cited rate and the self-citing rate were statistically assessed. In addition, Plastic and Reconstructive Surgery was compared with 15 top journals from other surgical specialties in 2015. IF was significantly correlated with the self-cited rate (R: 0.594, p = 0.001) and the self-citing rate (R: 0.824, p < 0.001). The self-cited rate of Plastic and Reconstructive Surgery in 2015 was higher than that of top journals from other surgical specialties. The IFs of Microsurgery and Journal of Cranio-Maxillo-Facial Surgery increased greatly in recent years, but they were inflated by high self-cited and self-citing rates. The self-citation rate positively affects the IF in plastic surgery journals. A high concentration of self-citation of some journals could distort the ranking among plastic surgery journals in general.

The scientific community views meta-analyses and systematic reviews, in addition to well-designed randomized controlled clinical trials, as the highest echelon in the continuum of hierarchy of evidence. The objective of this study was to examine the association between different study designs and citation counts of articles published in the American Journal of Orthodontics and Dentofacial Orthopedics and Angle Orthodontist. All articles, excluding editorial comments, letters to the editor, commentaries, and special articles, that were published in the American Journal of Orthodontics and Dentofacial Orthopedics and Angle Orthodontist during the years 2004 and 2005 were examined in this study. The number of times an article was cited in the first 24 months after its publication was computed. The PubMed database was used to index the study design of the articles. The association between study design and citation counts was examined using the Kruskal-Wallis test. A multivariable negative binomial regression model was used to examine the association between citation count and study design along with several other confounding variables. A total of 624 articles were selected for analysis. Of these, there were 25 meta-analyses or review articles, 42 randomized clinical trials, 59 clinical trials, 48 animal studies, 64 case reports, and 386 quasiexperimental/miscellaneous study designs. The mean ± SD citation count was 1.04 ± 1.46. Nearly half of the articles (n = 311) were not cited even once during the observation period. Case reports were cited less frequently than meta-analyses or reviews (incident risk ratio, 0.37; 95% confidence interval, 0.19 to 0.72; P = .003), even after adjusting for other independent variables. Among various study designs, meta-analyses and review articles are more likely to be cited in the first 24 months after publication. This study demonstrates the importance of publishing more meta-analyses and review articles for quicker dissemination of

Document review on the attempt to verify the way Qualis uses for ranking journals cited by the post-graduate programs of Medicine III in their evaluation periods, and the impact factors obtained by journals indexing base. The classification is annual and are ranking in strata ranging from A1, the highest, and A2; B1; B2; B3; B4; B5; C. The latter has zero evaluation weight. These strata take as reference the impact factor of the journals listed by the programs. The same journal can be classified into different Qualis in other areas, and this is no inconsistency, but expressed the assigned value, in each area, at that particular journal. The Impact Factor is measured using the Journal of Citation Report in Web of Knowledge website. Using the criteria established by WebQualis for stratification of journals there is a quality guidance of what is produced by the program and, based on it, can be made scientific comparison of program performance. Consulting the JCR is recommended because it defines exactly what is the journal's impact factor; Qualis stratifies numerical intervals and not individual journal specificity.

To analyze the impact of articles published in English compared to those published in Spanish in multilingual Spanish biomedical journals. We analyzed the language of publication, the number of original articles, the nationality of the authors, the citations received, the citing article and the nationality of the citing authors among the articles published from 2008-2012 in 5 multilingual Spanish biomedical journals. The study included 4,296 documents, 85 of which were published in English (2%). The percentage of original articles and of non-Spanish authorship was significantly higher among these latter articles and they also achieved more citations and more citing articles per article published. The proportion of articles published in English by multilingual Spanish biomedical journals is low and they are more often originals signed exclusively by foreign authors and receive more citations than those published in Spanish, which are also more frequently made by foreign authors.

Current science evaluation still relies on citation performance, despite criticisms of purely bibliometric research assessments. Biological taxonomy suffers from a drain of knowledge and manpower, with poor citation performance commonly held as one reason for this impediment. But is there really such a citation impediment in taxonomy? We compared the citation numbers of 306 taxonomic and 2291 non-taxonomic research articles (2009–2012) on mosses, orchids, ciliates, ants, and snakes, using Web of Science (WoS) and correcting for journal visibility. For three of the five taxa, significant differences were absent in citation numbers between taxonomic and non-taxonomic papers. This was also true for all taxa combined, although taxonomic papers received more citations than non-taxonomic ones. Our results show that, contrary to common belief, taxonomic contributions do not generally reduce a journal's citation performance and might even increase it. The scope of many journals rarely featuring taxonomy would allow editors to encourage a larger number of taxonomic submissions. Moreover, between 1993 and 2012, taxonomic publications accumulated faster than those from all biological fields. However, less than half of the taxonomic studies were published in journals in WoS. Thus, editors of highly visible journals inviting taxonomic contributions could benefit from taxonomy's strong momentum. The taxonomic output could increase even more than at its current growth rate if: (i) taxonomists currently publishing on other topics returned to taxonomy and (ii) non-taxonomists identifying the need for taxonomic acts started publishing these, possibly in collaboration with taxonomists. Finally, considering the high number of taxonomic papers attracted by the journal Zootaxa, we expect that the taxonomic community would indeed use increased chances of publishing in WoS indexed journals. We conclude that taxonomy's standing in the present citation-focused scientific landscape could

The paper deals with structure, importance and advantage as well as the path of development of the Uniform requirements for manuscripts submitted to biomedical journals (Vancouver style) from 1978, when they were established and firstly published, through changes and amendments up to their last--fourth edition. Authorship, abstract, key words and literature citation are fields dealt with in detail with appropriate discussions. The 16 year long existence of the Vancouver style, a great number of journals with high impact factor which conform to its requirements, as well as its advantages presented in the paper, should be a sufficient reason for scientists, explorers and editors of biomedical journals to conform to the requirements if they have not conformed to them yet.

Plagiarism Continues to Affect Scholarly Journals.

I have encountered 3 cases of plagiarism as editor of the Journal of Korean Medical Science (JKMS). The first one was copying figures from a JKMS article without citation, the second was submission of a copied manuscript of a published article to JKMS, and the third was publishing a copied JKMS article in another journal. The first and third cases violated copyrights of JKMS, but the violating journals made no action on the misconduct. The second and third cases were slightly modified copies of the source articles but similarity check by the Crosscheck could not identify the text overlap initially and after one year reported 96% overlap for the second case. The similarity of the third case was reported 3%. The Crosscheck must upgrade its system for better reliable screening of text plagiarism. The copy of the second case was committed by a corrupt Chinese editing company and also by some unethical researchers. In conclusion, plagiarism still threatens the trustworthiness of the publishing enterprises and is a cumbersome burden for editors of scholarly journals. We require a better system to increase the vigilance and to prevent the misconduct.

2018-05-03

This study aimed to characterize articles in popular general radiology journals that go uncited for a decade after publication. Using the Web of Science database, we identified annual citation counts for 13,459 articles published in Radiology, American Journal of Roentgenology, and Academic Radiology between 1997 and 2006. From this article cohort, we then identified all original research articles that accrued zero citations within a decade of publication. A concurrent equal-sized cohort of most cited articles was created. Numerous characteristics of the uncited and most cited articles were identified and compared. Only 47 uncited articles went uncited for a decade after publication. When compared to the 47 most cited articles over that same window, the uncited articles were significantly (P < .05) less likely to have a clinical focus, include a nonradiologist author and authors from multiple institutions and multiple nations, report research funding support and statistically significant findings, and include punctuation marks in their titles. Compared to the most cited articles, uncited articles also had significantly (P < .05) fewer authors, abstract words, manuscript words, references, tables, figure parts, and pages, as well as smaller subject sample sizes. Of articles published in popular general radiology journals, only a very small number of original research investigations remained uncited a decade after publication. Given that citations reflect the impact of radiology research, this observation suggests that journals are appropriately selecting meaningful work. Investigators seeking to avoid futile publication might consider their research initiatives in light of these characteristics. Copyright © 2018 The Association of University Radiologists.

We evaluated the top 13 journals in trauma and orthopaedics by impact factor and looked at the longer-term effect regarding citations of their papers. All 4951 papers published in these journals during 2007 and 2008 were reviewed and categorised by their type, subspecialty and super-specialty. All citations indexed through Google Scholar were reviewed to establish the rate of citation per paper at two, four and five years post-publication. The top five journals published a total of 1986 papers. Only three (0.15%) were on operative orthopaedic surgery and none were on trauma. Most (n = 1084, 54.5%) were about experimental basic science. Surgical papers had a lower rate of citation (2.18) at two years than basic science or clinical medical papers (4.68). However, by four years the rates were similar (26.57 for surgery, 30.35 for basic science/medical), which suggests that there is a considerable time lag before clinical surgical research has an impact. We conclude that high impact journals do not address clinical research in surgery and when they do, there is a delay before such papers are cited. We suggest that a rate of citation at five years post-publication might be a more appropriate indicator of importance for papers in our specialty.

To perform an extensive analysis of journals in Medicine III - CAPES, and specifically those in the areas of Otorhinolaryngology, Orthopedics and Traumatology and Chest Surgery. An active search for the impact factors in the Journal Citation Reports, Scimago, their indexation in Scielo, Lilacs, Scopus and Google Scholar, and their stratification in WebQualis was done. Forty-four journals with measured impact factors ranging from 3.006 to 0.128 were detected in the area of Otorhinolaryngology; however, only 26 of them (60%) had a Qualis measured by CAPES; in the stratification, no journal was detected in A1, three were A2 and nine B1. Three journals were located for Chest Surgery, with only one of them having a measured Qualis (A2) with a mean of 3.61. Sixty-seven journals were detected for Orthopedics and Traumatology, with an impact factor ranging from 4.699 to 0.156; Qualis was measured in only 38 of them (60%); there were three journal stratified as A1, seven as A2 and 25 as B1. The search for journals of higher impact induces authors to not publish in journals related to their area and facing more difficulties than investigators from other areas.

Increases in price during the last twenty years were studied for the journals listed in the 1983 Brandon list, and during the last fifteen years for all medical journals and for U.S. periodicals overall. When compared with increases in the Consumer Price Index (CPI), prices in all three categories of publications have increased much more rapidly than have prices overall. Libraries whose journal-acquisition budgets increased merely at the same rate as the CPI during the periods examined today can purchase only 50% to 70% of the journals they purchased in 1963. This information should help librarians justify budget increases. PMID:6652296

The reason of higher number of citations of some articles is discussed. Some considerations about the journals' impact factor, its merits and its pitfalls are also made. Scientific journals' impact factor, popularized by the Institute for Scientific Information, has become an objective parameter for authors' evaluation and also for institutions and other related circumstances. There is no reason for the impact factor's gap between some English journals and those written in other languages. English journals probably benefit of the "Mathew's effect", according to which eminent scientists are more rewarded by similar contributions than others less known. It is paradoxical that most of the major achievements of our age do not appear among the 100 most cited articles. There is no homogeneity among all the articles appearing in each scientific journal: half of the articles are cited ten times more than the other half. However, those articles cited 0 times are credited like the better ones. Each article should be evaluated by its own citations, which would be its impact factor; the authors should be evaluated by their H index. Copyright AULA MEDICA EDICIONES 2014.

The science that deals with evaluation of a scientific article refer to the finding quantitative indicators (index) of the scientific research success is called scientometrics. Scientometrics is part of scientology (the science of science) that analyzes scientific papers and their citations in a selected sample of scientific journals. There are four indexes by which it is possible to measure the validity of scientific research: number of articles, impact factor of the journal, the number and order of authors and citations number. Every scientific article is a record of the data written by the rules recommended by several scientific associations and committees. Growing number of authors and lot of authors with same name and surname led to the introduction of the necessary identification agent - ORCID number.

To assess the emerging use of Twitter by urological journals. A search of the Journal of Citation Reports 2012 was performed to identify urological journals. These journals were then searched on Twitter.com. Each journal website was accessed for links to social media (SoMe). The number of 'tweets', followers and age of profile was determined. To evaluate the content, over a 6-month period (November 2013 to April 2014), all tweets were scrutinised on the journals Twitter profiles. To assess SoMe influence, the Klout score of each journal was also calculated. In all, 33 urological journals were identified. Eight (24.2%) had Twitter profiles. The mean (range) number of tweets and followers was 557 (19-1809) and 1845 (82-3692), respectively. The mean (range) age of the twitter profiles was 952 (314-1758) days with an average 0.88 tweets/day. A Twitter profile was associated with a higher mean impact factor of the journal (mean [sd] 3.588 [3.05] vs 1.78 [0.99], P = 0.013). Over a 6-month period, November 2013 to April 2014, the median (range) number of tweets per profile was 82 (2-415) and the median (range) number of articles linked to tweets was 73 (0-336). Of these 710 articles, 152 were Level 1 evidence-based articles, 101 Level 2, 278 Level 3 and 179 Level 4. The median (range) Klout score was 47 (19-58). The Klout scores of major journals did not exactly mirror their impact factors. SoMe is increasingly becoming an adjunct to traditional teaching methods, due to its convenient and user-friendly platform. Recently, many of the leading urological journals have used Twitter to highlight significant articles of interest to readers. © 2014 The Authors. BJU International © 2014 BJU International.

2010-06-01

The citation impact of a comprehensive sample of articles published in social and personality psychology journals in 1998 was evaluated. Potential predictors of the 10-yr. citation impact of 1580 articles from 37 journals were investigated, including number of authors, number of references, journal impact factor, author nationality, and article length, using linear regression. The impact factor of the journal in which articles appeared was the primary predictor of the citations that they accrued, accounting for 30% of the total variance. Articles with greater length, more references, and more authors were cited relatively often, although the citation advantage of longer articles was not proportionate to their length. A citation advantage was also enjoyed by authors from the United States of America, Canada, and the United Kingdom. 37% of the variance in the total number of citations was accounted for by the study variables.

Even though an increasing portion of biomedical research today relies on the use of bioresources, at present biobankers are not able to trace this use in scientific literature and measure its impact with a variety of citation metrics. The “BRIF (Bioresource Research Impact Factor) and journal editors” subgroup was created precisely with the aim to study this issue and to build a standardized system to cite bioresources in journal articles. This report aims at presenting a guideline for Citation of BioResources in journal Articles (CoBRA). The guideline offers for the first time a standard for citing bioresources (including biobanks) within journal articles. It will increase their visibility and promote their sharing. PMID:27314833

A multi-objective decision-making approach to the journal submission problem.

PubMed

Wong, Tony E; Srikrishnan, Vivek; Hadka, David; Keller, Klaus

2017-01-01

When researchers complete a manuscript, they need to choose a journal to which they will submit the study. This decision requires to navigate trade-offs between multiple objectives. One objective is to share the new knowledge as widely as possible. Citation counts can serve as a proxy to quantify this objective. A second objective is to minimize the time commitment put into sharing the research, which may be estimated by the total time from initial submission to final decision. A third objective is to minimize the number of rejections and resubmissions. Thus, researchers often consider the trade-offs between the objectives of (i) maximizing citations, (ii) minimizing time-to-decision, and (iii) minimizing the number of resubmissions. To complicate matters further, this is a decision with multiple, potentially conflicting, decision-maker rationalities. Co-authors might have different preferences, for example about publishing fast versus maximizing citations. These diverging preferences can lead to conflicting trade-offs between objectives. Here, we apply a multi-objective decision analytical framework to identify the Pareto-front between these objectives and determine the set of journal submission pathways that balance these objectives for three stages of a researcher's career. We find multiple strategies that researchers might pursue, depending on how they value minimizing risk and effort relative to maximizing citations. The sequences that maximize expected citations within each strategy are generally similar, regardless of time horizon. We find that the "conditional impact factor"-impact factor times acceptance rate-is a suitable heuristic method for ranking journals, to strike a balance between minimizing effort objectives and maximizing citation count. Finally, we examine potential co-author tension resulting from differing rationalities by mapping out each researcher's preferred Pareto front and identifying compromise submission strategies.

A journal impact factor represents the mean number of citations per article published. Designed as one tool to measure the relative importance of a journal, impact factors are often incorporated into academic evaluation of investigators. The authors sought to determine how impact factors of emergency medicine (EM) journals compare to journals from other medical and surgical specialties and if any change has taken place over time. The 2010 impact factors and 5-year impact factors for each journal indexed by the Thomson Reuters ISI Web of Knowledge Journal Citation Reports (JCR) were collected, and EM, medical, and surgical specialties were evaluated. The maximum, median, and interquartile range (IQR) of the current impact factor and 5-year impact factor in each journal category were determined, and specialties were ranked according to the summary statistics. The "top three" impact factor journals for each specialty were analyzed, and growth trends from 2001 through 2010 were examined with random effects linear regression. Data from 2,287 journals in 31 specialties were examined. There were 23 EM journals with a current maximum impact factor of 4.177, median of 1.269, and IQR of 0.400 to 2.176. Of 23 EM journals, 57% had a 5-year impact factor available, with a maximum of 4.531, median of 1.325, and IQR of 0.741 to 2.435. The top three EM journals had a mean standard deviation (±SD) impact factor of 3.801 (±0.621) and median of 4.142 and a mean (±SD) 5-year impact factor of 3.788 (±1.091) and median of 4.297, with a growth trend of 0.211 (95% confidence interval [CI] = 0.177 to 0.245; p < 0.001). By any criterion analyzed, EM journals ranked no higher than 24th among 31 specialties. Emergency medicine journals rank low in impact factor summary statistics and growth trends among 31 medical and surgical specialties. © 2012 by the Society for Academic Emergency Medicine.

To examine the relationships between study quality, author prestige, journal impact factors, and citation rates of trials and to examine whether journal impact factors mediated the relationships between study quality and author prestige on citation rates. We used bibliometric data from 128 controlled trials included in a recent meta-analysis on brief alcohol interventions for adolescents and young adults. We obtained the number of citations from ISI Web of Knowledge and Google Scholar; journal impact factors were obtained from ISI Web of Knowledge. Linear regression models were used to examine the direct and indirect effects of interest. The results indicated that studies were published in journals with higher impact factors when first authors had higher h-indices and studies were funded, but this was largely because those studies were of higher quality. Studies were cited more frequently when first authors had higher h-indices and studies were funded, even after adjusting for study quality proxies. The observed associations between study quality and author prestige on citation rates were also partly mediated through journal impact factors. We conclude that studies conducted by more established authors and reported in more prestigious journal outlets are more likely to be cited by other scholars, even after controlling for various proxies of study quality.

Inequality in societies, academic institutions and science journals: Gini and k-indices

NASA Astrophysics Data System (ADS)

Ghosh, Asim; Chattopadhyay, Nachiketa; Chakrabarti, Bikas K.

2014-09-01

Social inequality is traditionally measured by the Gini-index (g). The g-index takes values from 0 to 1 where g=0 represents complete equality and g=1 represents complete inequality. Most of the estimates of the income or wealth data indicate the g value to be widely dispersed across the countries of the world: g values typically range from 0.30 to 0.65 at a particular time (year). We estimated similarly the Gini-index for the citations earned by the yearly publications of various academic institutions and the science journals. The ISI web of science data suggests remarkably strong inequality and universality (g=0.70±0.07) across all the universities and institutions of the world, while for the journals we find g=0.65±0.15 for any typical year. We define a new inequality measure, namely the k-index, saying that the cumulative income or citations of (1-k) fraction of people or papers exceed those earned by the fraction (k) of the people or publications respectively. We find, while the k-index value for income ranges from 0.60 to 0.75 for income distributions across the world, it has a value around 0.75±0.05 for different universities and institutions across the world and around 0.77±0.10 for the science journals. Apart from above indices, we also analyze the same institution and journal citation data by measuring Pietra index and median index.

There are some negative and positive impacts for the authors' paper and journals' reputation if mandatory citation of a paper or set of papers is requested. These effects can be different based on the recommended papers for citing in the new research. Mandatory citation has various types discussed in this paper. Self-citation and its reasons and impacts are also discussed in the present study.

To define the 100 citation classic papers of interventional radiology. Using the database of Journal Citation Reports the 40 highest impact factor radiology journals were chosen. From these journals the 100 most cited interventional radiology papers were chosen and analysed. The top paper received 2497 citations and the 100(th) paper 200 citations. The average number of citations was 320. Dates of publication ranged from 1953 - 2005. Most papers originated in the United States (n = 67) followed by Italy (n = 20) and France (n = 10). Harvard University (n = 18) and Osped Civile (n = 11) were the most prolific institutions. Ten journals produced all of the top 100 papers with "Radiology" and "AJR" making up the majority. SN Goldberg and T Livraghi were the most prolific authors. Nearly two thirds of the papers (n = 61) were published after 1990. This analysis identifies many of the landmark interventional radiology papers and provides a fascinating insight into the changing discourse within the field. It also identifies topics, authors and institutions which have impacted greatly on the specialty.

The aim of the study was to analyze the 100 most cited publications with Turkish origin in the Web of Science Otorhinolaryngology (ORL) journals. The Web of Science database was searched in terms of citations for publications originating from Turkey in ORL journals since 1983. After the identification of the 100 most cited articles, analysis was performed for the first author, institution, city, publication type, subject related to subspecialty, and journals having the most cited articles. Moreover, the number of ORL publications and citations of countries was determined in descending order using the same database. A total of 3948 ORL articles with Turkish origin was identified. The number of citations was 181 for the first and 28 for the last in the 100 most cited articles. As there was more than one article with 28 citations, 101 articles were analyzed. The number of the articles was 76, 22, and 3 for the university, education/research, and state hospitals, respectively. Hacettepe University, Ankara Numune Hospital, and Gazi University were the three leading institutions having the most cited articles, and Ankara was the first city. While 98 of 101 articles were original research, the number of case reports and review articles were 2 and 1, respectively. Thirty-five articles were related to otology, 23 to pediatric ORL, 20 to rhinology and head and neck surgery, and 3 to facial plastic surgery. Laryngoscope, Otolaryngology-Head and Neck Surgery, and International Journal of Pediatric Otorhinolaryngology were the leading 3 journals with the most cited articles coming from Turkey. The evaluation of countries revealed that Turkey was among the first 10 countries in terms of number of ORL articles but fell behind for the number of citations. This bibliometric study is the first one regarding the contribution of Turkish authors and institutions to ORL literature. Similar studies might be periodically repeated to determine national development in the field of ORL and

Purpose: The issue of retaining retrospective print journals is examined in light of the shift to electronic titles, the reallocation of library budgets from print to electronic, and the changing research practices of today's library users. This article also examines the evolving role of the physical library and its impact on space allocation. Methods: To determine current practice and opinion, a survey of health sciences librarians and academic librarians was conducted. To demonstrate the use patterns of older journal issues, citation analyses and interlibrary loan statistics were examined. Results: All methods indicate that recent material is accessed more frequently than older material, with a significant drop in use of materials greater than 15 years old. Materials greater than 20 years old constituted less than 5% of interlibrary loans and less than 9% of articles noted in the citation analysis. Conclusions: It is possible to eliminate older years of a print journal collection without a large impact on the needs of researchers. Librarians' preference to maintain full runs of journal titles may be motivated by reasons outside of actual usage or patrons needs. PMID:17082829

The importance and prestige of a scientific journal is increasingly being judged by the number of times the articles it publishes are cited or referenced in articles published in other scientific journals. Citation counting is also used to assess the merits of individual scientists when academic promotion and tenure are decided. With the help of Thomson, Institute for Scientific Information (Thomson ISI) a citation database was created for six leading forensic science and legal medicine journals. This database was used to determine the most highly cited articles, authors, journals and the most prolific authors of articles in the forensic sciences. The forensic science and legal medicine journals evaluated were: Journal of Forensic Sciences (JFS), Forensic Science International (FSI), International Journal of Legal Medicine (IJLM), Medicine, Science and the Law (MSL), American Journal of Forensic Medicine and Pathology (AJFMP), and Science and Justice (S&J). The resulting forensics database contained 14,210 papers published between 1981 and 2003. This in-depth bibliometric analysis has identified the creme de la creme in forensic science and legal medicine in a quantitative and objective way by citation analysis with focus on articles, authors and journals.

A method for selecting and rating scientific and professional journals representing the discipline of ergonomics and human factors is proposed. The method is based upon the journal list, impact factors and citations provided by the Institute of Scientific Information (ISI), and the journal list published in the Ergonomics Abstracts. Three groups of journals were distinguished. The 'ergonomics journals' focus exclusively on ergonomics and human factors. The 'related journals' focus on other disciplines than ergonomics and human factors, but regularly publish ergonomics/human factors papers. The 'basic journals' focus on other technical, medical or social sciences than ergonomics, but are important for the development of ergonomics/human factors. Journal quality was rated using a maximum of four categories: top quality (A-level), high quality (B-level), good quality (C-level)) and professional (P-level). The above methods were applied to develop the Ergonomics Journal List 2004. A total of 25 'ergonomics journals', 58 'related journals' and 142 'basic journals' were classified.

The aims of this study were to identify the most cited articles in Periodontology published from January 1990 to March 2005; and to analyse the differences between citation Classics and less cited articles. The search was carried out in four international periodontal journals: Journal of Periodontology, Journal of Clinical Periodontology, International Journal of Periodontics and Restorative Dentistry and Journal of Periodontal Research. The Classics, that are articles cited at least 100 times, were identified using the Science Citation Index database. From every issue of the journals that contained a Classic, another article was randomly selected and used as a Control. Fifty-five Classics and 55 Controls were identified. Classic articles were longer, used more images, had more authors, and contained more self-references than Controls. Moreover Classics had on the average a bigger sample size, often dealt with etiopathogenesis and prognosis, but were rarely controlled or randomized studies. Classic articles play an instructive role, but are often non-Controlled studies.

Complementary and alternative medicine (CAM) comprises a multitude of disciplines, for example, acupuncture, ayurvedic medicine, biofeedback, herbal medicine, and homeopathic medicine. While research on CAM interventions has increased and the CAM literature has proliferated since the mid-1990s, a number of our colleagues have expressed difficulties in deciding where to publish CAM articles. In response, we created a short guide to peer-reviewed MEDLINE-indexed journals that publish CAM articles. We examined numerous English-language sources to identify titles that met our criteria, whether specific to or overlapping CAM. A few of the resources in which we found the journal titles that we included are Alternative Medicine Foundation, American Holistic Nurses Association, CINAHL/Nursing Database, Journal Citation Reports database, MEDLINE, PubMed, and Research Council for Complementary Medicine. We organized the 69 selected titles for easy use by creating 2 user-friendly tables, one listing titles in alphabetical order and one listing them in topical categories. A few examples of the topical categories are Acupuncture, CAM (general), Chinese Medicine, Herbal/Plant/Phytotherapy, Neuroscience/Psychology, Nursing/Clinical Care. Our study is the first to list general CAM journals, specialty CAM journals, and overlapping mainstream journals that are peer reviewed, in English, and indexed in MEDLINE. Our goal was to assist both authors seeking publication and mainstream journal editors who receive an overabundance of publishable articles but must recommend that authors seek publication elsewhere due to space and priority issues. Publishing in journals indexed by and included in MEDLINE (or PubMed) ensures that citations to articles will be found easily. Copyright © 2012 Lippincott Williams & Wilkins.

After 36 years of continued publication of the journal Nutrición Hospitalaria, a list with the ten most cited articles published in it is elaborated. The top ten most cited articles in the world literature and stratification according to language, English or Spanish, subject, or period of time published are also analyzed. Nutr Hosp is the most important Ibero latin American nutrition journal. Nutr Hosp published 369 items in 2014 gaining the fourth position among all the world's journals devoted to nutrition. Article publication in English, or simultaneously in Spanish and English and Open Access policy probably benefit the number of citations. Copyright AULA MEDICA EDICIONES 2014.
