    Many scientists attempt to publish their work in a journal with the highest possible journal impact factor (IF). Despite widespread condemnation of the use of journal IFs to assess the significance of published work, these numbers continue to be widely misused in publication, hiring, funding, and promotion decisions (1, 2).

  3. Median Citation Index vs Journal Impact Factor

    The Journal Impact Factor is an arithmetic mean: It is the average number of citations, in a year, to a journal's articles that were published the previous two years. But for the vast majority of scholarly journals, the distribution of these citations is skewed (non-symmetric). We argue that a more representative member of the skewed distribution of citations is its median, not the mean. We thus introduce the Median Citation Index (MCI) and compare it to the journal Impact Factor (JIF) as a potentially more suitable choice of the ``center'' of the distribution, or its typical value. Unlike the JIF, the MCI is far less sensitive to outlier (very highly cited) papers or to gaming, and does not lend itself to the hype of calculating it to three decimal digits.

    Objective This study gathered information about the retraction policies of the top 200 scientific journals, ranked by impact factor. Methods Editors of the top 200 science journals for the year 2012 were contacted by email. Results One hundred forty-seven journals (74%) responded to a request for information. Of these, 95 (65%) had a retraction policy. Of journals with a retraction policy, 94% had a policy that allows the editors to retract articles without authors’ consent. Conclusions The majority of journals in this sample had a retraction policy, and almost all of them would retract an article without the authors’ permission. PMID:26213505

    Journal quality metrics (also referred to as bibliometrics), such as impact factors, are increasingly being used as a measure of researchers' and educators' success and prestige. Occupational therapists who submit articles to peer-reviewed journals may face a professional and research dilemma: Do they submit their articles to journals that largely have a professional audience and potentially do not have an impact factor, or do they opt not to publish their research material in occupational therapy-oriented journals? Occupational therapy authors can consider other journal quality metric alternatives, in addition to the impact factor option, including the Eigenfactor Score, Article Influence Score, h-index, SCImago Journal Rank (SJR), Source Normalised Impact per Paper (SNIP), and discipline-specific generated journal quality measures. These other journal quality metrics can be important reference points for occupational therapists who publish and may encourage authors to publish in journals relevant to the discipline. This process, in turn, will build the occupational therapy body of knowledge as well as provide an essential, growing reference source for evidence-based practice. PMID:21675341

    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

    In this study we gathered data on the misconduct policies of social science journals and combined it with the data from our previous study on journal misconduct policies, which did not include enough social science journals for data analysis. Consistent with our earlier finding, impact factor of the journal was the only variable significantly associated with whether a journal had a formal (written) misconduct policy with an odds-ratio of 1.72 (p < 0.01). We did not find that type of science (physical, biomedical, or social) or publisher had a significant effect on whether a journal had a policy. Another important finding is that less than half of the journals that responded to the survey had a formal misconduct policy. PMID:20306350

    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).

    Background Journal impact factor (IF) is linked to the probability of a paper being cited and is progressively becoming incorporated into researchers' curricula vitae. Furthermore, the decision as to which journal a given study should be submitted, may well be based on the trend in the journal's overall quality. This study sought to assess time trends in journal IF in the field of public, environmental and occupational health. Methods We used the IFs of 80 public health journals that were registered by the Science Citation Index from 1992 through 2003 and had been listed for a minimum period of the previous 3 years. Impact factor time trends were assessed using a linear regression model, in which the dependent variable was IF and the independent variable, the year. The slope of the model and its statistical significance were taken as the indicator of annual change. Results The IF range for the journals covered went from 0.18 to 5.2 in 2003. Although there was no statistical association between annual change and mean IF, most of the fastest growing journals registered mean IFs in excess of 1.5, and some represented emerging areas of public health research. Graphs displaying IF trends are shown. Conclusion In view of the delay between the publication of IFs and that of any given paper, knowing the trend in IF is essential in order to make a correct choice of journal. PMID:15777471

    To correct the incongruence of document types between the numerator and denominator in the traditional impact factor (IF), we make a corresponding adjustment to its formula and present five corrective IFs: IFTotal/Total, IFTotal/AREL, IFAR/AR, IFAREL/AR, and IFAREL/AREL. Based on a survey of researchers in the fields of ophthalmology and mathematics, we obtained the real impact ranking of sample journals in the minds of peer experts. The correlations between various IFs and questionnaire score were analyzed to verify their journal evaluation effects. The results show that it is scientific and reasonable to use five corrective IFs for journal evaluation for both ophthalmology and mathematics. For ophthalmology, the journal evaluation effects of the five corrective IFs are superior than those of traditional IF: the corrective effect of IFAR/AR is the best, IFAREL/AR is better than IFTotal/Total, followed by IFTotal/AREL, and IFAREL/AREL. For mathematics, the journal evaluation effect of traditional IF is superior than those of the five corrective IFs: the corrective effect of IFTotal/Total is best, IFAREL/AR is better than IFTotal/AREL and IFAREL/AREL, and the corrective effect of IFAR/AR is the worst. In conclusion, not all disciplinary journal IF need correction. The results in the current paper show that to correct the IF of ophthalmologic journals may be valuable, but it seems to be meaningless for mathematic journals. PMID:26977697

  16. Inflated impact factors? The true impact of evolutionary papers in non-evolutionary journals.

    PubMed

    Postma, Erik

    2007-01-01

    Amongst the numerous problems associated with the use of impact factors as a measure of quality are the systematic differences in impact factors that exist among scientific fields. While in theory this can be circumvented by limiting comparisons to journals within the same field, for a diverse and multidisciplinary field like evolutionary biology, in which the majority of papers are published in journals that publish both evolutionary and non-evolutionary papers, this is impossible. However, a journal's overall impact factor may well be a poor predictor for the impact of its evolutionary papers. The extremely high impact factors of some multidisciplinary journals, for example, are by many believed to be driven mostly by publications from other fields. Despite plenty of speculation, however, we know as yet very little about the true impact of evolutionary papers in journals not specifically classified as evolutionary. Here I present, for a wide range of journals, an analysis of the number of evolutionary papers they publish and their average impact. I show that there are large differences in impact among evolutionary and non-evolutionary papers within journals; while the impact of evolutionary papers published in multidisciplinary journals is substantially overestimated by their overall impact factor, the impact of evolutionary papers in many of the more specialized, non-evolutionary journals is significantly underestimated. This suggests that, for evolutionary biologists, publishing in high-impact multidisciplinary journals should not receive as much weight as it does now, while evolutionary papers in more narrowly defined journals are currently undervalued. Importantly, however, their ranking remains largely unaffected. While journal impact factors may thus indeed provide a meaningful qualitative measure of impact, a fair quantitative comparison requires a more sophisticated journal classification system, together with multiple field-specific impact statistics per

  18. 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

    A considerable part of the scientific community is, at least to some degree, involved in the "impact factor game". Editors strive to increase their journals' impact factor (IF) in order to gain influence in the fields of basic and applied research and scientists seek to profit from the "added value" of publishing in top IF journals. In this article we point out the most common "tricks" of engineering and manipulating the IF undertaken by a portion of professionals of the scientific publishing industry. They attempt to increase the nominator or decrease the denominator of the IF equation by taking advantage of certain design flaws and disadvantages of the IF that permit a degree of artificial and arbitrary inflation. Some of these practices, if not scientifically unethical, are at least questionable and should be abandoned. Editors and publishers should strive for quality through fair and thoughtful selection of papers forwarded for peer review and editorial comments that enhance the quality and scientific accuracy of a manuscript.

  3. A Large-Scale Analysis of Impact Factor Biased Journal Self-Citations

    PubMed Central

    Waltman, Ludo

    2016-01-01

    Based on three decades of citation data from across scientific fields of science, we study trends in impact factor biased self-citations of scholarly journals, using a purpose-built and easy to use citation based measure. Our measure is given by the ratio between i) the relative share of journal self-citations to papers published in the last two years, and ii) the relative share of journal self-citations to papers published in preceding years. A ratio higher than one suggests that a journal’s impact factor is disproportionally affected (inflated) by self-citations. Using recently reported survey data, we show that there is a relation between high values of our proposed measure and coercive journal self-citation malpractices. We use our measure to perform a large-scale analysis of impact factor biased journal self-citations. Our main empirical result is, that the share of journals for which our measure has a (very) high value has remained stable between the 1980s and the early 2000s, but has since risen strongly in all fields of science. This time span corresponds well with the growing obsession with the impact factor as a journal evaluation measure over the last decade. Taken together, this suggests a trend of increasingly pervasive journal self-citation malpractices, with all due unwanted consequences such as inflated perceived importance of journals and biased journal rankings.

  4. Impact factors of forensic science and toxicology journals: what do the numbers really mean?

    PubMed

    Jones, A W

    2003-04-23

    This article presents review and opinion about the use and abuse of journal impact factors for judging the importance and prestige of scientific journals in the field of forensic science and toxicology. The application of impact factors for evaluating the published work of individual scientists is also discussed. The impact factor of a particular journal is calculated by dividing the number of current year citations to a journal's articles that were published in the previous 2 years by the total number of citable items (articles and reviews) published in the same 2-year period. Journal impact factors differ from discipline to discipline and range from 0 for a journal whose articles are not cited in the previous 2 years to 46 for a journal where the average recent article is cited 46 times per year. The impact factor reflects the citation rate of the average article in a journal and not a specific article. Many parameters influence the citation rate of a particular journal's articles and, therefore, its impact factor. These include the visibility and size of the circulation of the journal including availability of electronic formats and options for on-line search and retrieval. Other things to consider are editorial standards especially rapid and effective peer-reviewing and a short time lag between acceptance and appearance in print. The number of self-citations and citation density (the ratio of references to articles) and also the inclusion of many review articles containing hundreds of references to recently published articles will boost the impact factor. Judging the importance of a scientist's work based on the average or median impact factor of the journals used to publish articles is not recommended. Instead an article-by-article citation count should be done, but this involves much more time and effort. Moreover, some weighting factor is necessary to allow for the number of co-authors on each article and the relative positioning of the individual names

    2015-01-01

    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. PMID:26667681

    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

    The notion of an impact factor was first posited by Eugene Garfield (1972) to study the use, prestige, and status of scientific journals. The Institute for Scientific Information created the impact factor as a means to measure the number of times an "average article" published in a journal was cited over a particular time period ("The impact…

    Both the concept and the application of the impact factor (IF) have been subject to widespread critique, including concerns over its potential manipulation. This study provides a systematic analysis of significant journal Impact Factor changes, based on the relative contribution of either one or both variables of the IF equation (i.e. citations / articles as the numerator / denominator of the quotient). A cohort of JCR-listed journals which faced the most dramatic absolute IF changes between 2013 and 2014 (ΔIF ≥ 3.0, n = 49) was analyzed for the causes resulting in IF changes that theses journals have experienced in the last five years. Along with the variation by number of articles and citations, this analysis includes the relative change of both variables compared to each other and offers a classification of `valid`and `invalid`scenarios of IF variation in terms of the intended goal of the IF to measure journal quality. The sample cohort features a considerable incidence of IF increases (18%) which are qualified as `invalid`according to this classification because the IF increase is merely based on a favorably changing number of articles (denominator). The results of this analysis point out the potentially delusive effect of IF increases gained through effective shrinkage of publication output. Therefore, careful consideration of the details of the IF equation and possible implementation of control mechanisms versus the volatile factor of number of articles may help to improve the expressiveness of this metric.

    The incentive structure of a scientist’s life is increasingly mimicking economic principles. While intensely criticized, the journal impact factor (JIF) has taken a role as the new currency for scientists. Successful goal-directed behavior in academia thus requires knowledge about the JIF. Using functional neuroimaging we examined how the JIF, as a powerful incentive in academia, has shaped the behavior of scientists and the reward signal in the striatum. We demonstrate that the reward signal in the nucleus accumbens increases with higher JIF during the anticipation of a publication and found a positive correlation with the personal publication record (pJIF) supporting the notion that scientists have incorporated the predominant reward principle of the scientific community in their reward system. The implications of this behavioral adaptation within the ecological niche of the scientist’s habitat remain unknown, but may also have effects which were not intended by the community.

    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

(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. PMID:25525577

    Journal Impact Factor (JIF) has been used in assessing scientific journals. Other indices, h- and g-indices and Article Influence Score (AIS), have been developed to overcome some limitations of JIF. The aims of this study were, first, to critically assess the use of JIF and other parameters related to medical education research, and second, to discuss the capacity of these indices in assessing research productivity as well as their utility in academic promotion. The JIF of 16 medical education journals from 2000 to 2011 was examined together with the research evidence about JIF in assessing research outcomes of medical educators. The findings were discussed in light of the nonnumerical criteria often used in academic promotion. In conclusion, JIF was not designed for assessing individual or group research performance, and it seems unsuitable for such purposes. Although the g- and h-indices have demonstrated promising outcomes, further developments are needed for their use as academic promotion criteria. For top academic positions, additional criteria could include leadership, evidence of international impact, and contributions to the advancement of knowledge with regard to medical education.

    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

    Most researchers acknowledge an intrinsic hierarchy in the scholarly journals ("journal rank") that they submit their work to, and adjust not only their submission but also their reading strategies accordingly. On the other hand, much has been written about the negative effects of institutionalizing journal rank as an impact measure. So far, contributions to the debate concerning the limitations of journal rank as a scientific impact assessment tool have either lacked data, or relied on only a few studies. In this review, we present the most recent and pertinent data on the consequences of our current scholarly communication system with respect to various measures of scientific quality (such as utility/citations, methodological soundness, expert ratings or retractions). These data corroborate previous hypotheses: using journal rank as an assessment tool is bad scientific practice. Moreover, the data lead us to argue that any journal rank (not only the currently-favored Impact Factor) would have this negative impact. Therefore, we suggest that abandoning journals altogether, in favor of a library-based scholarly communication system, will ultimately be necessary. This new system will use modern information technology to vastly improve the filter, sort and discovery functions of the current journal system. PMID:23805088

    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

    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

    Background Influential medical journals shape medical science and practice and their prestige is usually appraised by citation impact metrics, such as the journal impact factor. However, how permanent are medical journals and how stable is their impact over time? Methods and Results We evaluated what happened to general medical journals that were publishing papers half a century ago, in 1959. Data were retrieved from ISI Web of Science for citations and PubMed (Journals function) for journal history. Of 27 eligible journals publishing in 1959, 4 have stopped circulation (including two of the most prestigious journals in 1959) and another 7 changed name between 1959 and 2009. Only 6 of these 27 journals have been published continuously with their initial name since they started circulation. The citation impact of papers published in 1959 gives a very different picture from the current journal impact factor; the correlation between the two is non-significant and very close to zero. Only 13 of the 5,223 papers published in 1959 received at least 5 citations in 2009. Conclusions Journals are more permanent entities than single papers, but they are also subject to major change and their relative prominence can change markedly over time. PMID:20824146

    Background Research collaboration contributes to the advancement of knowledge by exploiting the results of scientific efforts more efficiently, but the global patterns of collaboration on meta-analysis are unknown. The purpose of this research was to describe and characterize the global collaborative patterns in meta-analyses of randomized trials published in high impact factor medical journals over the past three decades. Methods This was a cross-sectional, social network analysis. We searched PubMed for relevant meta-analyses of randomized trials published up to December 2012. We selected meta-analyses (including at least randomized trials as primary evidence source) published in the top seven high impact factor general medical journals (according to Journal Citation Reports 2011): The New England Journal of Medicine, The Lancet, the BMJ, JAMA, Annals of Internal Medicine, Archives of Internal Medicine (now renamed JAMA Internal Medicine), and PLoS Medicine. Opinion articles, conceptual papers, narrative reviews, reviews without meta-analysis, reviews of reviews, and other study designs were excluded. Results Overall, we included 736 meta-analyses, in which 3,178 authors, 891 institutions, and 51 countries participated. The BMJ was the journal that published the greatest number of articles (39%), followed by The Lancet (18%), JAMA (15%) and the Archives of Internal Medicine (15%). The USA, the UK, and Canada headed the absolute global productivity ranking in number of papers. The 64 authors and the 39 institutions with the highest publication rates were identified. We also found 82 clusters of authors (one group with 55 members and one group with 54 members) and 19 clusters of institutions (one major group with 76 members). The most prolific authors were mainly affiliated with the University of Oxford (UK), McMaster University (Canada), and the University of Bern (Switzerland).

  10. Milestones and Impact Factors

    PubMed Central

    2010-01-01

    Environmental Health has just received its first Impact Factor by Thomson ISI. At a level of 2.48, this achievement is quite satisfactory and places Environmental Health in the top 25% of environmental science journals. When the journal was launched in 2002, it was still unclear whether the Open Access publishing model could be made into a viable commercial enterprise within the biomedical field. During the past eight years, Open Access journals have become widely available, although still covering only about 15% of journal titles. Major funding agencies and institutions, including prominent US universities, now require that researchers publish in Open Access journals. Because of the profound role of scientific journals for the sharing of results and communication between researchers, the advent of Open Access may be of as much significance as the transition from handwriting to printing via moveable type. As Environmental Health is an electronic Open Access journal, the numbers of downloads at the journal website can be retrieved. The top-20 list of articles most frequently accessed shows that all of them have been downloaded over 10,000 times. Back in 2002, the first article published was accessed only 49 times during the following month. A year later, the server had over 1,000 downloads per month, and now the total number of monthly downloads approaches 50,000. These statistics complement the Impact Factor and confirm the viability of Open Access in our field of research. The advent of digital media and its decentralized mode of distribution - the internet - have dramatically changed the control and financing of scientific information dissemination, while facilitating peer review, accelerating editorial handling, and supporting much needed transparency. Both the meaning and means of "having an impact" are therefore changing, as will the degree and way in which scientific journals remain "factors" in that impact. PMID:20615249

    2007-01-01

    Nobody doubts the importance of the scientific performance's evaluation. The journal impact factor is increasingly employed to evaluate the quality of scientific research. The use of term "impact factor" has gradually evolved, especially in Europe, to include both journal and author impact. This ambiguity often causes problems. It is one thing to use impact factors to compare journals and quite another to use them to compare authors. Journals impact factors generally involve relatively large numbers of articles and citations. Individual authors, on average, produce much smaller numbers of articles. Many scientists consider that impact factor is not the perfect tool to measure the quality of articles but there is nothing better and it has the advantage of already being in existence and is, therefore, a good technique for scientific evaluation. However, the use of journal impact factor is probably the most controversial issue. PMID:17918300

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

    Cosco, Theodore D.

    2015-01-01

    Background: 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. Methods: 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. Results: 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. Interpretation: 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. PMID:26644544

    2014-01-01

    Introduction Both the Accreditation Council for Graduate Medical Education (ACGME) and the American Osteopathic Association (AOA) require core faculty to engage in scholarly work, including publication in peer-reviewed journals. With the ACGME/AOA merger, we sought to evaluate the frequency of publication in high-impact peer-reviewed EM journals from authors affiliated with osteopathic emergency medicine (EM) programs. Methods We performed a retrospective literature review using the Journal Citation Report database and identified the top five journals in the category of ‘Emergency Medicine’ by their 2011 Impact Factor. We examined all publications from each journal for 2011. For each article we recorded article type, authors’ names, position of authorship (first, senior or other), the author’s degree and affiliated institution. We present the data in raw numbers and percentages. Results The 2011 EM journals with the highest impact factor were the following: Annals of Emergency Medicine, Resuscitation, Journal of Trauma, Injury, and Academic Emergency Medicine. Of the 9,298 authors published in these journals in 2011; 1,309 (15%) claimed affiliation with U.S.-based EM programs, of which 16 (1%) listed their affiliations with eight different osteopathic EM programs. The 16 authors claimed affiliation with 8 of 46 osteopathic EM programs (17%), while 1,301 authors claimed affiliation with 104 of 148 (70%) U.S.-based allopathic programs. Conclusion Authors from osteopathic EM programs are under-represented in the top EM journals. With the pending ACGME/AOA merger, there is a significant opportunity for improvement in the rate of publication of osteopathic EM programs in top tier EM journals. PMID:25493152

    Rationale This study aimed to investigate the quality of reporting of anesthesia and euthanasia in experimental studies in small laboratory mammals published in the top ten impact factor journals. Methods A descriptive systematic review was conducted and data was abstracted from the ten highest ranked journals with respect to impact factor in the categories ‘Anesthesiology’, ‘Critical Care Medicine’ and ‘Respiratory System’ as defined by the 2012 Journal Citation Reports. Inclusion criteria according to PICOS criteria were as follows: 1) population: small laboratory mammals; 2) intervention: any form of anesthesia and/or euthanasia; 3) comparison: not specified; 4) primary outcome: type of anesthesia, anesthetic agents and type of euthanasia; secondary outcome: animal characteristics, monitoring, mechanical ventilation, fluid management, postoperative pain therapy, animal care approval, sample size calculation and performed interventions; 5) study: experimental studies. Anesthesia, euthanasia, and monitoring were analyzed per performed intervention in each article. Results The search yielded 845 articles with 1,041 interventions of interest. Throughout the manuscripts we found poor quality and frequency of reporting with respect to completeness of data on animal characteristics as well as euthanasia, while anesthesia (732/1041, 70.3%) and interventions without survival (970/1041, 93.2%) per se were frequently reported. Premedication and neuromuscular blocking agents were reported in 169/732 (23.1%) and 38/732 (5.2%) interventions, respectively. Frequency of reporting of analgesia during (117/610, 19.1%) and after painful procedures (38/364, 10.4%) was low. Euthanasia practice was reported as anesthesia (348/501, 69%), transcardial perfusion (37/501, 8%), carbon dioxide (26/501, 6%), decapitation (22/501, 5%), exsanguination (23/501, 5%), other (25/501, 5%) and not specified (20/501, 4%, respectively. Conclusions The present systematic review revealed

    Is the best measure of a scientist's worth the total number of his or her published papers? For many years Institute for Scientific Information has been publishing the lists of impact factors providing quantitative tools for ranking scientists. The impact factor was devised by Eugene Garfield, the founder of the Institute for Scientific Information. Impact factors are calculated each year by the Institute for Scientific Information for those journals which it indexes, and are published in Journal Citation Reports. These measures apply only to journals, not individual articles or individual scientists. For the impact factor of individual scientists, there exists the h-index or Hirsch number. The Hirsch-index (h-index) has recently been defined by Hirsch as a new method for measuring the scientific activity. If a scientist has published n articles which all have been cited at least n times, then he will have a h-index of n . The h-index seeks to describe the impact of individual researchers, rather than journals. The h-index is the result of the balance between the number of publications and the number of citations per publication. H-index: Impact of Individual Scientists. H-index or/and impact factor - it is the question of the future. PMID:17468068

    2011-01-01

    Background To assist educators and researchers in improving the quality of medical research, we surveyed the editors and statistical reviewers of high-impact medical journals to ascertain the most frequent and critical statistical errors in submitted manuscripts. Findings The Editors-in-Chief and statistical reviewers of the 38 medical journals with the highest impact factor in the 2007 Science Journal Citation Report and the 2007 Social Science Journal Citation Report were invited to complete an online survey about the statistical and design problems they most frequently found in manuscripts. Content analysis of the responses identified major issues. Editors and statistical reviewers (n = 25) from 20 journals responded. Respondents described problems that we classified into two, broad themes: A. statistical and sampling issues and B. inadequate reporting clarity or completeness. Problems included in the first theme were (1) inappropriate or incomplete analysis, including violations of model assumptions and analysis errors, (2) uninformed use of propensity scores, (3) failing to account for clustering in data analysis, (4) improperly addressing missing data, and (5) power/sample size concerns. Issues subsumed under the second theme were (1) Inadequate description of the methods and analysis and (2) Misstatement of results, including undue emphasis on p-values and incorrect inferences and interpretations. Conclusions The scientific quality of submitted manuscripts would increase if researchers addressed these common design, analytical, and reporting issues. Improving the application and presentation of quantitative methods in scholarly manuscripts is essential to advancing medical research. PMID:21854631

  3. Bridging knowledge translation gap in health in developing countries: visibility, impact and publishing standards in journals from the Eastern Mediterranean

    2012-01-01

    Background 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. Methods 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. Results 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%). Conclusion 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.

    The impact factor (IF) of scientific journals has acquired a major role in the evaluations of the output of scholars, departments and whole institutions. Typically papers appearing in journals with large values of the IF receive a high weight in such evaluations. However, at the end of the day one is interested in assessing the impact of individuals, rather than papers. Here we introduce Author Impact Factor (AIF), which is the extension of the IF to authors. The AIF of an author A in year t is the average number of citations given by papers published in year t to papers published by A in a period of Δt years before year t. Due to its intrinsic dynamic character, AIF is capable to capture trends and variations of the impact of the scientific output of scholars in time, unlike the h-index, which is a growing measure taking into account the whole career path.

    Casadevall, Arturo; Fang, Ferric C.

    2014-01-01

    ABSTRACT Numerous essays have addressed the misuse of the journal impact factor for judging the value of science, but the practice continues, primarily as a result of the actions of scientists themselves. This seemingly irrational behavior is referred to as “impact factor mania.” Although the literature on the impact factor is extensive, little has been written on the underlying causes of impact factor mania. In this perspective, we consider the reasons for the persistence of impact factor mania and its pernicious effects on science. We conclude that impact factor mania persists because it confers significant benefits to individual scientists and journals. Impact factor mania is a variation of the economic theory known as the “tragedy of the commons,” in which scientists act rationally in their own self-interests despite the detrimental consequences of their actions on the overall scientific enterprise. Various measures to reduce the influence of the impact factor are considered. PMID:24643863

    2014-01-01

    The Journal of Global Health (JoGH) is three years old. To assess its impact, we analysed online access to JoGH's articles using PubMed Central and Google Analytics tools. Moreover, we tracked citations that JoGH received in 2013 using ISI Web of KnowledgeSM and Google Scholar® tools. The 66 items (articles, viewpoints and editorials) published between June 2011 and December 2013 were accessed more than 50 000 times during 2013, from more than 160 countries of the world. Seven among the 13 most accessed papers were focused on global, regional and national epidemiological estimates of important infectious diseases. JoGH articles published in 2011 and 2012 received 77 citations in Journal Citation Reports® (JCR)–indexed journals in 2013 to 24 original research articles, setting our first, unofficial impact factor at 3.208. In addition, JoGH received 11 citations during 2013 to its 12 original research papers published during 2013, resulting in an immediacy index of 0.917. The number of external, non–commissioned submissions that we consider to be of high quality is continuously increasing, leading to current JoGH's rejection rate of about 80%. The current citation analysis raises favourable expectations for the JoGH's overall impact on the global health community in future years. PMID:24976952

  9. Publication trends of shared decision making in 15 high impact medical journals: a full-text review with bibliometric analysis

    2014-01-01

    Background Shared Decision Making (SDM) is increasingly advocated as a model for medical decision making. However, there is still low use of SDM in clinical practice. High impact factor journals might represent an efficient way for its dissemination. We aimed to identify and characterize publication trends of SDM in 15 high impact medical journals. Methods We selected the 15 general and internal medicine journals with the highest impact factor publishing original articles, letters and editorials. We retrieved publications from 1996 to 2011 through the full-text search function on each journal website and abstracted bibliometric data. We included publications of any type containing the phrase “shared decision making” or five other variants in their abstract or full text. These were referred to as SDM publications. A polynomial Poisson regression model with logarithmic link function was used to assess the evolution across the period of the number of SDM publications according to publication characteristics. Results We identified 1285 SDM publications out of 229,179 publications in 15 journals from 1996 to 2011. The absolute number of SDM publications by journal ranged from 2 to 273 over 16 years. SDM publications increased both in absolute and relative numbers per year, from 46 (0.32% relative to all publications from the 15 journals) in 1996 to 165 (1.17%) in 2011. This growth was exponential (P < 0.01). We found fewer research publications (465, 36.2% of all SDM publications) than non-research publications, which included non-systematic reviews, letters, and editorials. The increase of research publications across time was linear. Full-text search retrieved ten times more SDM publications than a similar PubMed search (1285 vs. 119 respectively). Conclusion This review in full-text showed that SDM publications increased exponentially in major medical journals from 1996 to 2011. This growth might reflect an increased dissemination of the SDM concept to the

    2004-01-01

    Purpose: The purpose is to review the issue of retraction in the scientific literature and to examine the policies on retraction of major biomedical journals. Method: The historical background of this issue was investigated through a literature search. The Instructions to Authors of 122 major biomedical journals were reviewed for evidence of a policy on the retraction of articles. Editors of those journals with no mention of retraction in their Instructions to Authors were contacted by email and/or postal mail. Results: Sixty-two percent of the journals investigated did not post or report having a policy on issuing retractions. Only twenty-one (18%) did. The remainder did not post any policy and did not respond to inquiries. Discussion: Including policies in Instructions to Authors relating to the principled conduct of research and publication will improve the ethical environment in which the scientific community works.

    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.

  2. How to Rank Journals

    PubMed Central

    Bradshaw, Corey J. A.; Brook, Barry W.

    2016-01-01

    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.

  5. Is impact factor necessary for "Prilozi (Contributions)" and Macedonia?

    2013-01-01

    58 years after the creation of impact factor (IF) the professional public shows interest in IFs and their significance for academia and individuals. Really, is a medical journal with IF needed for Macedonia? Some other small and developing countries have pursued and accomplished this goal: Serbia, Slovenia, and Croatia. On the other hand the survey of publications in Macedonian medical journals has been found to lack quality. We believe that to strive to obtain an IF would be beneficial for all Macedonian interest groups involved. This would introduce an ambition among the members of Macedonian academia to publish (so far rare), than to publish in Pubmed listed journals (ambition present in very few Macedonian academics) and then to publish in journals with the highest IF possible (so far a very exclusive group of Macedonian medical professionals). In time this will help in creating and enforcing legal obligation for the academia for a promotion based on merit of IF scientific publications. We believe that this is possible only by Parliament legislation. This will be of benefit for Macedonian patients, the medical community and will unable this country to contribute to the universe of science. Lastly it would certainly be helpful in getting a Macedonian university in the prestigious first 500 Shangai list. Key words: impact factor, Macedonia, medical journals. PMID:24280884

Using citations extracted from the references and footnotes in these scholarly journals, the Psychology Citation Index for Japanese Papers was created. The citation impact factors in Japanese psychology was determined on the basis of the number of times a journal was cited, cumulative impact factors, and the cited half-life of the journal; five years was a valid period for impact factor of psychological journals in Japan. The changes in the 5-year impact factors of "Japanese Journal of Psychology" were reviewed by comparing it with other journals. PMID:23848002

    Objective The aim of this study was to assess adherence to the Consolidated Standards of Reporting Trials (CONSORT) for Abstracts by five high-impact general medical journals and to assess whether the quality of reporting was homogeneous across these journals. Design This is a descriptive, cross-sectional study. Setting Randomised controlled trial (RCT) abstracts in five high-impact general medical journals. Participants We used up to 100 RCT abstracts published between 2011 and 2014 from each of the following journals: The New England Journal of Medicine (NEJM), the Annals of Internal Medicine (Annals IM), The Lancet, the British Medical Journal (The BMJ) and the Journal of the American Medical Association (JAMA). Main outcome The primary outcome was per cent overall adherence to the 19-item CONSORT for Abstracts checklist. Secondary outcomes included per cent adherence in checklist subcategories and assessing homogeneity of reporting quality across the individual journals. Results Search results yielded 466 abstracts, 3 of which were later excluded as they were not RCTs. Analysis was performed on 463 abstracts (97 from NEJM, 66 from Annals IM, 100 from The Lancet, 100 from The BMJ, 100 from JAMA). Analysis of all scored items showed an overall adherence of 67% (95% CI 66% to 68%) to the CONSORT for Abstracts checklist. The Lancet had the highest overall adherence rate (78%; 95% CI 76% to 80%), whereas NEJM had the lowest (55%; 95% CI 53% to 57%). Adherence rates to 8 of the checklist items differed by >25% between journals. Conclusions Among the five highest impact general medical journals, there is variable and incomplete adherence to the CONSORT for Abstracts reporting checklist of randomised trials, with substantial differences between individual journals. Lack of adherence to the CONSORT for Abstracts reporting checklist by high-impact medical journals impedes critical appraisal of important studies. We recommend diligent assessment of adherence to reporting

    Background Publication of clinical research findings in prominent journals influences health beliefs and medical practice, in part by engendering news coverage. Randomized controlled trials (RCTs) should be most influential in guiding clinical practice. We determined whether study design of clinical research published in high-impact journals influences media coverage. Methods and Findings We compared the incidence and amount of media coverage of RCTs with that of observational studies published in the top 7 medical journals between 1 January 2013 and 31 March 2013. We specifically assessed media coverage of the most rigorous RCTs, those with >1000 participants that reported ‘hard’ outcomes. There was no difference between RCTs and observational studies in coverage by major newspapers or news agencies, or in total number of news stories generated (all P>0.63). Large RCTs reporting ‘hard’ outcomes did not generate more news coverage than small RCTs that reported surrogate outcomes and observational studies (all P>0.32). RCTs were more likely than observational studies to attract a journal editorial (70% vs 46%, P = 0.003), but less likely to be the subject of a journal press release (17% vs 50%, P<0.001). Large RCTs that reported ‘hard’ outcomes did not attract an editorial more frequently than other studies (61% vs 58%, P>0.99), nor were they more likely to be the subject of a journal press release (14% vs 38%, P = 0.14). Conclusions The design of clinical studies whose results are published in high-impact medical journals is not associated with the likelihood or amount of ensuing news coverage. PMID:26701758

    2015-01-01

    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).

    Beginning about three years ago, the world of academic publishing has become infected by fake impact factors and misleading metrics that are launched by bogus companies. The misleading metrics and fake impact factors have damaged the prestige and reliability of scientific research and scholarly journals. This article presents the in-depth story of some of the main bogus impact factors, how they approached the academic world, and how the author identified them. Some names that they use are Universal Impact Factor (UIF), Global Impact Factor (GIF), and Citefactor, and there even is a fake Thomson Reuters Company. PMID:26120416

    There is a natural tendency to judge a gift by the attractiveness of its wrapping. In some respect, this reflects current mores of measuring the gravitas of a scientific paper based on the journal cover in which the work appears. Most journals have an impact factor (IF) which some proudly display on their face page. Although historically journal IF has been a convenient quantitative shorthand, has its (mis)use contributed to inaccurate perceptions of the quality of scientific articles? Is now the time that equally convenient but more individually accurate metrics be adopted? PMID:17577403

    Objective To examine changes in representation of women among first authors of original research published in high impact general medical journals from 1994 to 2014 and investigate differences between journals. Design Observational study. Study sample All original research articles published in Annals of Internal Medicine, Archives of Internal Medicine, The BMJ, JAMA, The Lancet, and the New England Journal of Medicine (NEJM) for one issue every alternate month from February 1994 to June 2014. Main exposures Time and journal of publication. Main outcome measures Prevalence of female first authorship and its adjusted association with time of publication and journal, assessed using a multivariable logistic regression model that accounted for number of authors, study type and specialty/topic, continent where the study was conducted, and the interactions between journal and time of publication, study type, and continent. Estimates from this model were used to calculate adjusted odds ratios against the mean across the six journals, with 95% confidence intervals and P values to describe the associations of interest. Results The gender of the first author was determined for 3758 of the 3860 articles considered; 1273 (34%) were women. After adjustment, female first authorship increased significantly from 27% in 1994 to 37% in 2014 (P<0.001). The NEJM seemed to follow a different pattern, with female first authorship decreasing; it also seemed to decline in recent years in The BMJ but started substantially higher (approximately 40%), and The BMJ had the highest total proportion of female first authors. Compared with the mean across all six journals, first authors were significantly less likely to be female in the NEJM (adjusted odds ratio 0.68, 95% confidence interval 0.53 to 0.89) and significantly more likely to be female in The BMJ (1.30, 1.01 to 1.66) over the study period. Conclusions The representation of women among first authors of original research in high

    Although the English language is considered nowadays as the international language of medical publications, some important Spanish journals with impact factor in the Journal Citation Reports as Neurologia, they bet for the publication in Spanish. Neurologia is the official publication of the Sociedad Española de Neurología and there is the conviction that you can have a Spanish language journal with a high quality and a strong impact. Its presence in the most important international data bases and the possibility of free access to its contents through Internet guarantees its proper diffusion around the world. From the point of view of citation, the repercussion of the language for Neurologia, is reflected in the fact that the 46,8 % of the citations that receive are from journals that are published in Spanish. The main factor to improve the impact of the journal is the quality of their papers, as well as the fulfillment of the international rules about periodical publications, the punctuality in its edition and distribution, the presence in national and international bibliographical data bases, its free diffusion in Internet, the training of its researchers and their sensitivity to consult and cite articles that have been published in quality Spanish journals, when necessary.

    decreases the impact factor of journal. And for each editor and editorial board, impact factor is one of the main criterions used every year to measure the quality of the journal and their efforts to improve it. Impact factor is also an important criterion when applying for academic positions. This has resulted in some high-impact journals starting to publish separate editions of their journals with case reports only, but also with no or with very low impact factor. This is probably one of the reasons why we receive offers to publish all types of articles in different online open access journals on a daily basis. But of course, if you pay for it… Acta Dermatovenerologica Croatica is proud to be the official journal of the Croatian Dermatovenereological Society of the Croatian Medical Association and also be supported by the Croatian Ministry of Science. This gives us the freedom to make balanced content with some case reports per issue, all for free. But we of course also have to take care and try to increase our impact factor, so we try to encourage authors to publish their interesting case reports in the form of letters to the editor, which do not influence the impact factor so strongly but give us the opportunity to communicate our experiences. During this year we hope to make some improvements in the quality and visibility of our Journal, and to start the 25th anniversary of the journal with new impetus. PMID:27149124

    In recent decades, we have observed an intensification of science, technology and innovation activities in Brazil. The increase in production of scientific papers indexed in international databases, however, has not been accompanied by an equivalent increase in the impact of publications. This paper presents a methodology for analyzing production and the impact of certain research areas in Brazil related to two aspects: the origin of the journals (national or foreign) and international collaboration. These two variables were selected for being of particular importance in understanding the context of scientific production and communication in countries with emerging economies. The sample consisted of papers written by Brazilian researchers in 19 subfields of knowledge published from 2002 to 2011, totaling 85,082 papers. To calculate the impact, we adopted a normalized indicator called the relative subfield citedness (Rw) using a window of 5 years to obtain measurements evaluated in 2 different years: 2007 and 2012. The data on papers and citations were collected from the Web of Science database. From the results, we note that most of the subfields have presented, from one quinquennium to another, improved performance in the world production rankings. Regarding publication in national and foreign journals, we observed a trend in the distribution maintenance of production of the subfields based on the origin of the journal. Specifically, for impact, we identified a lower Rw pattern for Brazilian papers when they were published in national journals in all subfields. When Brazilian products are published in foreign journals, we observed a higher impact for those papers, even surpassing the average global impact in some subfields. For international collaboration, we analyzed the percentage of participation of foreign researchers and the connection between collaboration and the impact of papers, especially emphasizing the distinction of hyperauthorship papers in terms of

    This study examines the distribution of health outcomes research (HOR) studies in the clinical literature by clinical areas and journal impact factor. The authors reviewed 535 journals and divided the sample into higher and lower impact journals across four clinical area. Mann-Whitney and Kruskal-Wallis tests were used to examine differences across four categories of outcomes research articles published, specifically the incidence of articles in higher versus lower impact journals and differences across clinical areas. All high-impact journals published more safety and quality articles than process assessment, quality of life, or cost analysis studies. The number of each type of outcomes research study published was highly variable across all clinical areas. Only arthritis and outcomes research journals showed statistically significant differences between higher versus lower impact journals. Authors may benefit from considering these differences in their clinical specialty area when deciding where to submit HOR studies. PMID:21411472

    Farrar, Cathy

    As part of the National Science Foundation Science Literacy through Science Journalism (SciJourn) research and development initiative (http://www.scijourn.org ; Polman, Saul, Newman, and Farrar, 2008) a quasi-experimental design was used to investigate what impact incorporating science journalism activities had on students' scientific literacy. Over the course of a school year students participated in a variety of activities culminating in the production of science news articles for Scijourner, a regional print and online high school science news magazine. Participating teachers and SciJourn team members collaboratively developed activities focused on five aspects of scientific literacy: placing information into context, recognizing relevance, evaluating factual accuracy, use of multiple credible sources and information seeking processes. This study details the development process for the Scientific Literacy Assessment (SLA) including validity and reliability studies, evaluates student scientific literacy using the SLA, examines student SLA responses to provide a description of high school students' scientific literacy, and outlines implications of the findings in relation to the National Research Council's A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (2012) and classroom science teaching practices. Scientifically literate adults acting as experts in the assessment development phase informed the creation of a scoring guide that was used to analyze student responses. Experts tended to draw on both their understanding of science concepts and life experiences to formulate answers; paying close attention to scientific factual inaccuracies, sources of information, how new information fit into their view of science and society as well as targeted strategies for information seeking. Novices (i.e., students), in contrast, tended to ignore factual inaccuracies, showed little understanding about source credibility and suggested

    2014-01-01

    After changing its language from Korean or English to English only in 2010, the journal metrics of Diabetes & Metabolism Journal (DMJ) were analyzed to assess whether this change in the journal policy was successful. The journal metric items that were analyzed were the following: impact factor; total citations; countries of authors; proportion of the articles funded out of the total number of original articles; and Hirsch-index (H-index). A retrospective, descriptive analysis was carried out using various databases, such as KoreaMed, Korean Medical Citation Index (KoMCI), KoreaMed Synapse, Web of Science, and Journal Citation Ranking. The journal's impact factor was 2.054, which corresponds to 83/122 (68.0%) out of the 2012 JCR endocrinology and metabolism category. The number of the journal's total citations was 330 in 2013. In addition to Korean authors, authors from 13 other countries published papers in the journal from 2010 to 2013. The number of funded papers from 2010 to 2013 was 65 out of 148 original articles (43.9%). The journal's H-index from KoreaMed Synapse was 7, and that from Web of Science was 9. It can be concluded that changing the journal's language to English was successful based on journal metrics. DMJ is currently positioned as an international journal based on the international diversity of authors and editors, its sufficiently high proportion of funded articles, its relatively high impact factor, and the number of total citations.

    Characteristics of citation and language in publications of German authors from the journal "Der Chirurg" (vol 78, 2007) were analysed. Out of a total of 3,342 citations, 756 (22.62%) were from German authors with 248 (32.8) self-citations. The hegemony of the impact factor in science, research and education is critically discussed. The imbalance between the number of surgeons in the US and United Kingdom (66,032) and surgeons in the German speaking countries in Europe (25,300) is compared with respect to the counting methods used to create the impact factor of a journal. The creation of an independent impact factor in Europe and the development of an EU-based citation data bank which allows unselected access to national language scientific literature are strongly needed.

    Bibliometric indicators increasingly affect careers, funding, and reputation of individuals, their institutions and journals themselves. In contrast to author self-citations, little is known about kinetics of journal self-citations. Here we hypothesized that they may show a generalizable pattern within particular research fields or across multiple fields. We thus analyzed self-cites to 60 journals from three research fields (multidisciplinary sciences, parasitology, and information science). We also hypothesized that the kinetics of journal self-citations and citations received from other journals of the same publisher may differ from foreign citations. We analyzed the journals published the American Association for the Advancement of Science, Nature Publishing Group, and Editura Academiei Române. We found that although the kinetics of journal self-cites is generally faster compared to foreign cites, it shows some field-specific characteristics. Particularly in information science journals, the initial increase in a share of journal self-citations during post-publication year 0 was completely absent. Self-promoting journal self-citations of top-tier journals have rather indirect but negligible direct effects on bibliometric indicators, affecting just the immediacy index and marginally increasing the impact factor itself as long as the affected journals are well established in their fields. In contrast, other forms of journal self-citations and citation stacking may severely affect the impact factor, or other citation-based indices. We identified here a network consisting of three Romanian physics journals Proceedings of the Romanian Academy, Series A, Romanian Journal of Physics, and Romanian Reports in Physics, which displayed low to moderate ratio of journal self-citations, but which multiplied recently their impact factors, and were mutually responsible for 55.9%, 64.7% and 63.3% of citations within the impact factor calculation window to the three journals

  1. Where should family medicine papers be published - following the impact factor?

    PubMed

    Peleg, Roni; Shvartzman, Pesach

    2006-01-01

    Academic institutions weigh the research contribution of family physicians and take this factor into account when determining eligibility for the candidates' promotion. Among other parameters, these institutions consider the journals in which family physicians publish. In this respect, the impact factor (IF) has gained a foothold as one of the most accepted means to measure this contribution. The IF may be a measure of the main importance of a scientific journal. IF has a huge, but controversial, influence on the perception and evaluation of published scientific research. It is important for family physicians to understand and be aware of the importance of the IF and the way it is calculated. The IF is one consideration in the decision-making process of a researcher as to where to publish because the IF of most family medicine journals is less than 2.0. Thus publication in these journals might not yield the proper "score" for academic promotion in many institutions. On the other hand, publication in journals with higher IF that are not necessarily widely read by primary care physicians could result in a small impact of their findings on direct patient care.

    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. PMID:27247735

    Background: While it is widely accepted that scientific factors may render a study more likely to be accepted for publication, it is less clear whether nonscientific factors may also be associated with publication. The purpose of this study was to identify the nonscientific factors associated with acceptance for publication by The Journal of Bone and Joint Surgery (American Volume). Methods: A total of 1173 manuscripts submitted to The Journal of Bone and Joint Surgery between January 1, 2004, and June 30, 2005, for publication as scientific articles were analyzed as part of a study on publication bias in the editorial decision-making process. Information was collected on nonscientific factors plausibly associated with acceptance for publication, including study location, conflict-of-interest disclosure, sex of the author, primary language, and the number of prior publications by the corresponding author in frequently cited orthopaedic journals. The final disposition term (acceptance or rejection) was recorded, and logistic regression was used to identify factors associated with acceptance for publication. Results: Manuscripts from countries other than the United States or Canada were significantly less likely to be accepted (odds ratio, 0.51; 95% confidence interval, 0.28 to 0.92; p = 0.026). Factors positively associated with acceptance for publication were conflict-of-interest disclosure involving a nonprofit entity (odds ratio, 1.92; 95% confidence interval, 1.35 to 2.73; p < 0.001) and ten or more prior publications in frequently cited orthopaedic journals by the corresponding author (odds ratio, 2.01; 95% confidence interval, 1.33 to 3.05; p = 0.001). We did not find a significant association between acceptance and conflict-of-interest disclosure involving a for-profit company, sex of the corresponding author, or primary language. Conclusions: Manuscripts submitted to The Journal of Bone and Joint Surgery were more likely to be accepted if they were from the

    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. PMID:26714812

    Founded in 2005, Globalization and Health was the first open access global health journal. The journal has since expanded the field, and its influence, with the number of downloaded papers rising 17-fold, to over 4 million. Its ground-breaking papers, leading authors -including a Nobel Prize winner- and an impact factor of 2.25 place it among the top global health journals in the world. To mark the ten years since the journal's founding, we, members of the current editorial board, undertook a review of the journal's progress over the last decade. Through the application of an inductive thematic analysis, we systematically identified themes of research published in the journal from 2005 to 2014. We identify key areas the journal has promoted and consider these in the context of an existing framework, identify current gaps in global health research and highlight areas we, as a journal, would like to see strengthened.

    Abstract Background This study represents scientific production of Iran in medical sciences field at recent years, and the correlation between scientific productions with the number of indexed journals. Methods Data extracted from SCOPUS database between years 2000 and 2011, and Iran’s performance measured in terms of different Scientometrics indexes including self-citations, percent of cited articles, number of articles with international collaboration and contribution of Iran in medical sciences in Middle East and world. Moreover correlation between the number of articles, citations, self-citations, and H-index and number of indexed journals for 50 countries in all fields is included. Results In 2011 year, Iran contributed 32.77 percent of the Middle East, and accounted for 1.57 percent of the world scientific production. The most frequent document type was original journal article published in English. Retrieved records revealed preferred subject areas, including medicine miscellaneous (14.53 percent of Iran publications in 2011 year). In 2011, according to the number of articles and citations to them, Iran was at 17th and 23th position between 226 countries, respectively. After adjustment for 19708 journals from 50 countries, Iran’s rank based on the number of journals in medical sciences was 24th. Conclusion The number of indexed journals with number of articles, citations, self-citations, and H-index of each country showed significant correlation (P-value<0.01). In recent years, by favoring quality over quantity of researches, the new rules have proven to be more effective for discriminating Iranian scientific productions. PMID:26060621

    2014-01-01

    Histochemistry provides the unique opportunity to detect single molecules in the very place where they exert their structural roles or functional activities: this makes it possible to correlate structural organization and function, and may be fruitfully exploited in countless biomedical research topics. Aiming to estimate the impact of histochemical articles in the biomedical field, the last few years citations of articles published in a long-established histochemical journal have been considered. This brief survey suggests that histochemical journals, especially the ones open to a large spectrum of research subjects, do represent an irreplaceable source of information not only for cell biologists, microscopists or anatomists, but also for biochemists, molecular biologists and biotechnologists.

    Objective To investigate the effectiveness of open peer review as a mechanism to improve the reporting of randomised trials published in biomedical journals. Design Retrospective before and after study. Setting BioMed Central series medical journals. Sample 93 primary reports of randomised trials published in BMC-series medical journals in 2012. Main outcome measures Changes to the reporting of methodological aspects of randomised trials in manuscripts after peer review, based on the CONSORT checklist, corresponding peer reviewer reports, the type of changes requested, and the extent to which authors adhered to these requests. Results Of the 93 trial reports, 38% (n=35) did not describe the method of random sequence generation, 54% (n=50) concealment of allocation sequence, 50% (n=46) whether the study was blinded, 34% (n=32) the sample size calculation, 35% (n=33) specification of primary and secondary outcomes, 55% (n=51) results for the primary outcome, and 90% (n=84) details of the trial protocol. The number of changes between manuscript versions was relatively small; most involved adding new information or altering existing information. Most changes requested by peer reviewers had a positive impact on the reporting of the final manuscript—for example, adding or clarifying randomisation and blinding (n=27), sample size (n=15), primary and secondary outcomes (n=16), results for primary or secondary outcomes (n=14), and toning down conclusions to reflect the results (n=27). Some changes requested by peer reviewers, however, had a negative impact, such as adding additional unplanned analyses (n=15). Conclusion Peer reviewers fail to detect important deficiencies in reporting of the methods and results of randomised trials. The number of these changes requested by peer reviewers was relatively small. Although most had a positive impact, some were inappropriate and could have a negative impact on reporting in the final publication. PMID:24986891

    How do the various water resources journals stack up? This question is frequently asked at scientific meetings, within promotion and tenure committees, and around graduate student lunch counters. Several years ago G. Dagan (Eos, June 20,1989) published a very useful report of findings by the Institute for Scientific Information (ISI), which publishes annual reviews of scientometric indices. I read his report just after receiving my Ph.D., and the numbers greatly influenced my choice of where to publish my dissertation. For those graduate students and water resources professionals who may benefit from the latest figures, I report my compilation of the 1995 impact factors from ISI.

    ABSTRACT The reader is invited to travel to Ancient Greece, contemporary Brazil, and other places in a fantasy search for the best scientific journal. This whimsical search does not rely on the impact factor, the most popular tool used in real life for finding good journals. Instead, it takes advantage of the so-called authority factor, a recently proposed alternative to the impact factor. The authority factor of a particular journal is the mean h-index (Hirsch's index) of the most suitable group of this journal's editors. Having no connection to any major function of scientific journals, and also being arbitrary (which group of editors to select?), this factor is poorly suited for any technical analysis, but it seems to work well for “small-talk” editorials and self-promotion by complacent editors. Interestingly, the highest authority factor we could find belongs to the journal Temperature. This claim, however, should not be taken too seriously. PMID:27227057

    Objectives This study aimed to compare the impact of Gross Domestic Product (GDP) per capita, spending on Research and Development (R&D), number of universities, and Indexed Scientific Journals on total number of research documents (papers), citations per document and Hirsch index (H-index) in various science and social science subjects among Asian countries. Materials and Methods In this study, 40 Asian countries were included. The information regarding Asian countries, their GDP per capita, spending on R&D, total number of universities and indexed scientific journals were collected. We recorded the bibliometric indicators, including total number of research documents, citations per document and H-index in various science and social sciences subjects during the period 1996–2011. The main sources for information were World Bank, SCI-mago/Scopus and Web of Science; Thomson Reuters. Results The mean per capita GDP for all the Asian countries is 14448.31±2854.40 US$, yearly per capita spending on R&D 0.64±0.16 US$, number of universities 72.37±18.32 and mean number of ISI indexed journal per country is 17.97±7.35. The mean of research documents published in various science and social science subjects among all the Asian countries during the period 1996–2011 is 158086.92±69204.09; citations per document 8.67±0.48; and H-index 122.8±19.21. Spending on R&D, number of universities and indexed journals have a positive correlation with number of published documents, citations per document and H-index in various science and social science subjects. However, there was no association between the per capita GDP and research outcomes. Conclusion The Asian countries who spend more on R&D have a large number of universities and scientific indexed journals produced more in research outcomes including total number of research publication, citations per documents and H-index in various science and social science subjects.

    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.

    An array of potential ethical stumbling blocks awaits the editors of scientific journals. There are issues of particular relevance to mental health journals, and others unique to local journals with a relatively small circulation and low impact factor. The blind review system, conflict of interests, redundant publication, fraud and plagiarism, guest and ghost authorship and ghost writing, advertising, language and stigma, patient consent, and "rigging" the Impact Factor are all issues of importance. It is critical that editors are aware and informed of these important issues, and have an accessible forum for evaluating problems as they arise. PMID:25618285

    2015-01-01

    Background. Open access (OA) journals allows access to research papers free of charge to the reader. Traditionally, biomedical researchers use databases like MEDLINE and EMBASE to discover new advances. However, biomedical OA journals might not fulfill such databases’ criteria, hindering dissemination. The Directory of Open Access Journals (DOAJ) is a database exclusively listing OA journals. The aim of this study was to investigate DOAJ’s coverage of biomedical OA journals compared with the conventional biomedical databases. Methods. Information on all journals listed in four conventional biomedical databases (MEDLINE, PubMed Central, EMBASE and SCOPUS) and DOAJ were gathered. Journals were included if they were (1) actively publishing, (2) full OA, (3) prospectively indexed in one or more database, and (4) of biomedical subject. Impact factor and journal language were also collected. DOAJ was compared with conventional databases regarding the proportion of journals covered, along with their impact factor and publishing language. The proportion of journals with articles indexed by DOAJ was determined. Results. In total, 3,236 biomedical OA journals were included in the study. Of the included journals, 86.7% were listed in DOAJ. Combined, the conventional biomedical databases listed 75.0% of the journals; 18.7% in MEDLINE; 36.5% in PubMed Central; 51.5% in SCOPUS and 50.6% in EMBASE.

    Background. Open access (OA) journals allows access to research papers free of charge to the reader. Traditionally, biomedical researchers use databases like MEDLINE and EMBASE to discover new advances. However, biomedical OA journals might not fulfill such databases' criteria, hindering dissemination. The Directory of Open Access Journals (DOAJ) is a database exclusively listing OA journals. The aim of this study was to investigate DOAJ's coverage of biomedical OA journals compared with the conventional biomedical databases. Methods. Information on all journals listed in four conventional biomedical databases (MEDLINE, PubMed Central, EMBASE and SCOPUS) and DOAJ were gathered. Journals were included if they were (1) actively publishing, (2) full OA, (3) prospectively indexed in one or more database, and (4) of biomedical subject. Impact factor and journal language were also collected. DOAJ was compared with conventional databases regarding the proportion of journals covered, along with their impact factor and publishing language. The proportion of journals with articles indexed by DOAJ was determined. Results. In total, 3,236 biomedical OA journals were included in the study. Of the included journals, 86.7% were listed in DOAJ. Combined, the conventional biomedical databases listed 75.0% of the journals; 18.7% in MEDLINE; 36.5% in PubMed Central; 51.5% in SCOPUS and 50.6% in EMBASE. Of the journals in DOAJ, 88.7% published in English and 20.6% had received impact factor for 2012 compared with 93.5% and 26.0%, respectively, for journals in the conventional biomedical databases. A subset of 51.1% and 48.5% of the journals in DOAJ had articles indexed from 2012 and 2013, respectively. Of journals exclusively listed in DOAJ, one journal had received an impact factor for 2012, and 59.6% of the journals had no content from 2013 indexed in DOAJ. Conclusions. DOAJ is the most complete registry of biomedical OA journals compared with five conventional biomedical databases

    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

    Joinson, Carol

    Continence problems in children can persist into later childhood and have a serious effect on quality of life. Research into its causes and impact is scarce, and useful resources are limited. A Medical Research Council grant is funding a project at the University of Bristol, which aims to improve understanding of the risk factors and outcomes of continence problems in children and adolescents. This article outlines the initial findings, which could help in the production of resources for parents, children and young people. PMID:27386707

  12. "3 . . 2 . . 1 . . Impact [factor]: target [academic career] destroyed!": just another statistical casualty.

    PubMed

    Brumback, Roger A

    2012-12-01

    "Publish or perish" is the time-honored "principle" for academicians who race to accumulate lines under the "publications" section of a curriculum vitae. The original intent of publication-to inform others of findings and further scientific knowledge-has been corrupted by factors including (1) exponential growth of journals and the journal industry, fueled in part by intrusion of the Internet into all aspects of academic life; and (2) adoption of journal metrics (rather than written content) as the measure of scientific quality. The proprietary Thomson Reuters Impact Factor is the most pernicious metric, having caused editors and publishers to change editorial practices to boost the number. At the same time, gullible administrators and government agencies have been persuaded that metrics for the journal in which materials are published can be used as a measure of the worth of individual investigators (and institutions) and their research efforts: simple numbers can be substituted for the burdensome effort required to read and assess research quality. Thus, granting of research funds, awarding of academic rank and tenure, and determination of salaries (including bonus payments) have become tied to manipulable journal metrics rather than the significance or quality of reported research. Therefore, it is no wonder that the integrity of science is more often being questioned. How should a young investigator approach the "publish or perish" dilemma? Performing sound research and preparing optimal materials for publication must remain the overriding goals: properly articulate the question addressed by the study; thoroughly document all methods and case information; carefully describe results including any conflicting or negative findings; discuss the importance of the findings along with how the results address the initial question and whether findings refute or confirm previous studies; prepare properly cited bibliographic references; list all author contributions

    It is a privilege to be Editor-in-Chief of Journal of Optics at this exciting time when the use of light spearheads the development of new technologies in telecommunications, green energy, manufacturing, medicine and defence, just to mention a few. These technological advances, seen by many as the next photonic technological revolution, are underpinned by fundamental and applied research in the following key directions: Nanophotonics and plasmonics Metamaterials and structured photonic materials Nonlinear and ultrafast optics Photonics at the life science interface Information and communication optics Integrated optics systems and devices Material processing with light Propagation, diffraction and scattering This is where Journal of Optics focuses its attention. This editorial marks the first issue of the journal published under the abbreviated name (shortened from Journal of Optics A: Pure and Applied Optics). The name change is just one of a series of changes introduced in the last year, along with the 8 subject sections listed above and the appointment of Section Editors. With the name change, we will also update the look of the journal by introducing colour cover images which will feature some of the most exciting research in the journal. We have retained many of the journal's original selling points: we are found in thousands of libraries around the world, and will continue our policy of free web access to all papers for 30 days after publication, ensuring broad and unrestricted dissemination of your research results. We will also continue our strong and well respected special issue and topical review programmes and we are always grateful to receive new suggestions for special issues or review articles. Along with the Editorial Board, I would like to thank the authors, referees and readers who have contributed to the success of Journal of Optics.

    2015-02-01

    The present study aims to review the quality of open-access nursing journals listed in the Directory of Open Access Journals that published papers in 2013 with a nursing focus, written in English, and were freely accessible. Each journal was reviewed in relation to their publisher, year of commencement, number of papers published in 2013, fee for publication, indexing, impact factor, and evidence of requirements for ethics and disclosure statements. The quality of the journals was assessed by impact factors and the requirements for indexing in PubMed. A total of 552 were published in 2013 in the 19 open-access nursing journals that met the inclusion criteria. No journals had impact factors listed in Web of Knowledge, but three had low Scopus impact factors. Only five journals were indexed with PubMed. The quality of the 19 journals included in the review was evaluated as inferior to most subscription-fee journals. Mental health nursing has some responsibility to the general public, and in particular, consumers of mental health services and their families, for the quality of papers published in open-access journals. The way forward might involve dual-platform publication or a process that enables assessment of how research has improved clinical outcomes. PMID:25388929

  16. Medical Hypotheses 2006 impact factor rises to 1.3--a vindication of the 'editorial review' system for revolutionary science.

    PubMed

    Charlton, Bruce G

    2007-01-01

    The Thomson Scientific Impact Factor (IF) for Medical Hypotheses has risen to 1.299 for 2006. This means that the IF has more than doubled since 2004, when it stood at 0.607. Using Elsevier's Scopus database; in 2004 there were 437 citations to Medical Hypotheses papers published in the previous two years--by 2006 this had trebled to 1216 citations. Monthly internet usage of Medical Hypotheses run at an average of about 26000 papers downloaded per month. An IF of 1.3 means that Medical Hypotheses has now entered the mainstream level of 'respectable' medical journals, in terms of its usage by other scientists. This is particularly pleasing given the aim of the journal is to publish radical and speculative ideas. A healthy IF is important to Medical Hypotheses because the journal deploys a system of editorial review, rather than peer review, for evaluation and selection of papers. Editorial review involves selection of a journal's content primarily by an editor who has broad experience and competence in the field, assisted by a relatively small editorial advisory board. The great advantage of editorial review is that it is able, by policy, to favour the publication of revolutionary science. But since editorial review relies on hard-to-quantify and non-transparent individual judgments, it is important for its outcomes to be open to objective evaluations. Scientometric measures of usage such as citations, impact factors and downloads constitute objective evidence concerning a journal's usefulness. Since Medical Hypotheses is performing adequately by such criteria, this provides a powerful answer to those who fetishize peer review and regard any other system of evaluation as suspect. Journal review procedures are merely a means to the end, and the end is a journal that serves a useful function in the dynamic process of science. Medical Hypotheses can now claim to perform such a role. PMID:17706892

  13. Coherent measures of the impact of co-authors in peer review journals and in proceedings publications

    NASA Astrophysics Data System (ADS)

    Ausloos, Marcel

    2015-11-01

    This paper focuses on the coauthor effect in different types of publications, usually not equally respected in measuring research impact. A priori unexpected relationships are found between the total coauthor core value, ma, of a leading investigator (LI), and the related values for their publications in either peer review journals (j) or in proceedings (p). A surprisingly linear relationship is found: ma(j) + 0.4 ma(p) = ma(jp) . Furthermore, another relationship is found concerning the measure of the total number of citations, Aa, i.e. the surface of the citation size-rank histogram up to ma. Another linear relationship exists : Aa(j) + 1.36 Aa(p) = Aa(jp) . These empirical findings coefficients (0.4 and 1.36) are supported by considerations based on an empirical power law found between the number of joint publications of an author and the rank of a coauthor. Moreover, a simple power law relationship is found between ma and the number (rM) of coauthors of an LI: ma ≃ rMμ ; the power law exponent μ depends on the type (j or p) of publications. These simple relations, at this time limited to publications in physics, imply that coauthors are a "more positive measure" of a principal investigator role, in both types of scientific outputs, than the Hirsch index could indicate. Therefore, to scorn upon co-authors in publications, in particular in proceedings, is incorrect. On the contrary, the findings suggest an immediate test of coherence of scientific authorship in scientific policy processes.

    PubMed Central

    2014-01-01

    Background The International Journal of Mental Health Systems (IJMHS) was launched in August 2007 and has recently been given a formal impact factor. This study uses bibliometric indicators to review the performance of the Journal against its original stated objectives and aspirations. Methods All articles published in IJMHS since publication commenced were included (n = 158). Selected bibliometric measures indicating Journal productivity, author affiliation, impact, geographic reach, and international collaboration were utilised. Results IJMHS published 158 articles in seven volumes over six years. Articles with three to five authors constitute the dominant authorship pattern, and authors’ affiliations are varied. IJMHS has received an impact factor of 1.06 from Thomson Reuters, and the SCImago Journal Ranking shows IJMHS to be well positioned in the four categories in which it is listed, including in comparisons with well-established BMC journals that have similar scientific interests. Geographic authorship patterns show contributions from a large number of countries, including many low- and middle-income countries. Discussion Manuscript submissions from a wide range of countries, including low- and middle-income countries, are mostly from academic institutions. Authors from some geographic areas of the world are significantly under-represented. The calculation of an impact factor and encouraging rankings on the SCImago Journal Rank index are expected to lead to increased submission of high quality manuscripts. Conclusion The performance of IJMHS over the first six years is promising, and the Journal is on the way to achieving the aims set out in the inaugural Editorial. IJMHS will continue to enhance its current impact through a number of new initiatives, including the introduction of thematic series and a broader range of article categories. PMID:24393301

  16. Factors impacting bladder underactivity and clinical implications.

    PubMed

    Van Koeveringe, G A; Rademakers, K L J

    2015-06-01

    Lower urinary tract symptoms in the voiding phase can be due to an underactive bladder, but are usually similar to symptoms of infravesical obstruction or dysfunctional voiding. The underactive bladder can be caused by an impaired detrusor contraction but also by a derangement of local and central neuro-cognitive regulatory systems or an impairment of bladder sensation. Potential risk factors of bladder underactivity include: ageing, diabetes, neurogenic disease, cardiovascular disease, obstruction and psychological causes. Comprehensive diagnostic and detection techniques for an underactive detrusor are necessary. To establish the diagnosis and follow up new treatments, useful urodynamic parameters and threshold values have to be determined. As neuro-cognitive regulation plays an important role in the control of voiding, psychological factors have to be taken into account during the assessment in these patients. Ambulatory urodynamic techniques therefore have to be considered. Voiding is determined by the balance of both the detrusor contraction and the resistance of the bladder outlet, a dysfunction in one factor can be compensated by a counter-acting function of the other factor. Therefore, to predict voiding problems in the future, it will be indicated to assess the compensatory capacity of the detrusor contractility, contractile reserve, and the outlet relaxation capacity. If novel treatments and evaluation techniques have become available, it is likely that in the future, many patients that get a TURP now, can be treated by pharmacological agents directed towards increasing the bladder contractility in a balanced combination with medication directed towards lowering the bladder outlet resistance.

  17. Improving biomedical journals' ethical policies: the case of research misconduct.

    PubMed

    Bosch, Xavier

    2014-09-01

    Scientific journals may incur scientific error if articles are tainted by research misconduct. While some journals' ethical policies, especially those on conflicts of interest, have improved over recent years, with some adopting a uniform approach, only around half of biomedical journals, principally those with higher impact factors, currently have formal misconduct policies, mainly for handling allegations. Worryingly, since a response to allegations would reasonably require an a priori definition, far fewer journals have publicly available definitions of misconduct. While some journals and editors' associations have taken significant steps to prevent and detect misconduct and respond to allegations, the content, visibility of and access to these policies varies considerably. In addition, while the lack of misconduct policies may prompt and maintain a de novo approach for journals, potentially causing stress, publication delays and even legal disputes, the lack of uniformity may be a matter of contention for research stakeholders such as editors, authors and their institutions, and publishers. Although each case may need an individual approach, I argue that posting highly visible, readily accessible, comprehensive, consistent misconduct policies could prevent the publication of fraudulent papers, increase the number of retractions of already published papers and, perhaps, reduce research misconduct. Although legally problematic, a concerted approach, with sharing of information between editors, which is clearly explained in journal websites, could also help. Ideally, journals, editors' associations, and publishers should seek consistency and homogenise misconduct policies to maintain public confidence in the integrity of biomedical research publications.

    Memon, Rizwan Ahmed; Leung, Dennis Y C

    2010-01-01

    This study investigated the impact of important environmental variables (i.e., wind speed, solar radiation and cloud cover) on urban heating. Meteorological parameters for fifteen years (from 1990 to 2005), collected at a well developed and densely populated commercial area (Tsim Sha Tsui, Hong Kong), were analyzed in details. Urban heat island intensity (UHII), a well known indicator of urban heating, has been determined as the spatially averaged air-temperature difference between Tsim Sha Tsui and Ta Kwu Ling (a thinly populated rural area with lush vegetation). Results showed that the UHII and cloud cover have increased by around 9.3% and 4%, respectively, whereas the wind speed and solar radiation have decreased by around 24% and 8.5%, respectively. The month of December experienced the highest UHII (10.2 degrees C) but the lowest wind speed (2.6 m/sec) and cloud cover (3.8 oktas). Conversely, the month of April observed the highest increases in the UHII (over 100%) and the highest decreases in wind speed (over 40%) over fifteen years. Notably, the increases in the UHII and reductions in the wind speed were the highest during the night-time and early morning. Conversely, the intensity of solar radiation reduced while the intensity of urban cool island (UCII) increased during solar noon-time. Results demonstrated strong negative correlation between the UHII and wind speed (coefficient of determination, R2 = 0.8) but no negative correlation between UCII and solar radiation attenuation. A possible negative correlation between UHII and cloud cover was investigated but could not be substantiated. PMID:21462708

The last of these decrees authorized Colciencias, the Colombian government institute created to support scientific research in Colombia, to establish rules for its implementation. Colciencias decided to evaluate scientific papers produced in Colombia based on the non-scientific method of the "impact factor", and considered that citations in MEDLINE/PubMed and PsylNFO were second line publications thus violating Colombian law. This affects not only the progress of scientific research in Colombia but also researchers' income and puts Colombia's scientific journals and publications at great disadvantage. Scientific papers indexed in qualified databases such as MEDLINE/PubMed must be judged according to law in order to prevent further injuries to the developing Colombian scientific production.

    Objective: The aim of this study was to identify the publication speed (peer review time and publication time) of biomedical Indian journals and identify the journals having the facility of advance online publication (AOP). Materials and Methods: Biomedical Indian journals were identified from the Journal Citation Report of 2013. Thirty original articles published between January 2012 and June 2014 were systematically selected from each journal. Information about the date of submission, revision, and acceptance were extracted from the full text of the articles. Median peer review time (submission to acceptance) and publication time (acceptance to AOP/electronic publication) were calculated for each journal. Results: Of the 19 journals studied, 5 (26.3%), 15 (78.9%), and 6 (31.6%) journals did not mention details about date of submission, date of revision, and date of acceptance, respectively. The individual median peer review time of the journals ranged from 87 to 377.5 days and the combined median peer review time (interquartile range) was 143.5 days (105.5, 238). The individual median publication time ranged from 14 to 349 days. The publication time for journals with AOP was significantly lesser (29.5 [19.6, 50.6] vs. 146.5 [126.5, 202.5]; P = 0.02) compared to journals without AOP. Impact factor of the journal did not correlate with the publication speed. The facility of AOP was provided by 6 (31.6%) journals. Conclusions: Overall, the peer review time and publication time of biomedical Indian journals included in our study seems to be fairly long. Less than one-third of biomedical Indian journals provide the facility of AOP. PMID:26955575

    2014-01-01

    Over the past years, the European Journal of Engineering Education (EJEE), the journal of the European Society for Engineering Education (SEFI) developed as a more research oriented journal. Bibliometric analyses show that EJEE keeps pace with other leading journals in the field of Engineering Education in most respects. EJEE serves a worldwide audience with about as many contributions from Europe as from other parts of the world. Yet, the impact factor of the journal calculated according to the formula of Thomson's ISI Web of Science seems to be lagging behind. As an explanation for this phenomenon, it is argued that EJEE keeps on publishing papers that are appreciated by practitioners in the field, even if they do not generate a lot of citations in scientific journals.

    PubMed Central

    2016-01-01

    Purpose The aim was to verify if changing the Journal of Gastric Cancer (JGC) to only English (starting in December 2010) was successful based on bibliometrics. Materials and Methods The following indicators were retrieved or calculated from the journal homepage and the Web of Science Core Collection on January 30, 2016: the number of citable articles per year; the number of original articles funded; the national origins of the editorial board members and authors; the total citations; the impact factors; the national origins of authors citing the journal; the source titles of articles citing the journal; and the Hirsch index. Results From 2011 to 2015, the number of citable articles per year was 40, 41, 39, 39, and 40. The proportion of original articles funded was 39 out of 113 articles (34.5%). The editorial board members were from seven countries. The authors were from 11 countries. The total citations increased from 1 in 2011 to 245 in 2015. From 2013 to 2015, the impact factors (without self-citations) were 1.42, 1.36, and 1.60. In 2014, the value 1.60 corresponded to the ranking of 157 out of 210 oncology journals (74.8%); It was cited from 46 countries. Top-ranking countries of citing authors were China (171), Korea (158), and Japan (75). The number of source titles citing the journal was more than 100. The Hirsch index was 12. Conclusions The English-only language policy, which started in December 2010, was successful in promoting the JGC to international levels from the perspective of bibliometric analysis. PMID:27104021

    Volatilization of fumigants has been concerned as one of air pollution sources. Fumigants are used to control nematodes and soil-born pathogens for a pre-plant treatment to increase the production of high-cash crops. One of technologies to reduce the volatilization of fumigants to atmosphere is to enhance the degradation of fumigants in soil. Fumigant degradation is affected by environmental factors such as moisture content, temperature, initial concentration of injected fumigants, and soil properties. However, effects of each factor on the degradation were limitedly characterized and integrated Impacts from environmental factors has not been described yet. Degradation of 1,3- dichloropropene (1,3-D) was investigated in various condition of temperatures (20-60 °C), moisture contents (0 ¡V 30 %) and initial concentrations (0.6 ¡V 60 mg/kg) with Arlington sandy loam soil. Abiotic and biotic degradation processes were distinguished using two sterilization methods with HgCl2 and autoclave and impacts of environmental factors were separately assessed for abiotic and biotic degradations. Initially, degradation rates (k) of cis and trans 1,3-D isomers were estimated by first-order kinetics and modified depending on impacts from environmental factors. Arrhenius equation and Walker¡¦s equation which were conventionally used to describe temperature and moisture effects on degradation were assessed for integrated impacts from environmental factors and logarithmical correlation was observed between initial concentrations of applied fumigants and degradation rates. Understanding integrated impacts of environmental factors on degradation will help to design more effective emission reduction schemes in various conditions and provide more practical parameters for modeling simulations.

    Previous exploratory analyses suggest that the Oral Health Impact Profile (OHIP) consists of four correlated dimensions and that individual differences in OHIP total scores reflect an underlying higher-order factor. The aim of this report is to corroborate these findings in the Dimensions of Oral Health-Related Quality of Life (DOQ) Project, an international study of general population subjects and prosthodontic patients. Using the project's Validation Sample (n = 5022), we conducted confirmatory factor analyses in a sample of 4993 subjects with sufficiently complete data. In particular, we compared the psychometric performance of three models: a unidimensional model, a four-factor model and a bifactor model that included one general factor and four group factors. Using model-fit criteria and factor interpretability as guides, the four-factor model was deemed best in terms of strong item loadings, model fit (RMSEA = 0·05, CFI = 0·99) and interpretability. These results corroborate our previous findings that four highly correlated factors - which we have named Oral Function, Oro-facial Pain, Oro-facial Appearance and Psychosocial Impact - can be reliably extracted from the OHIP item pool. However, the good fit of the unidimensional model and the high interfactor correlations in the four-factor solution suggest that OHRQoL can also be sufficiently described with one score.

    2010-07-01

    Publication in quality journals has long been a yardstick for measuring academic performance, although there is a divergence of opinions as to how to define and measure "journal quality". For some time the primary tools for assessing journal quality have been the ISI Journal Citation Reports and the Journal Impact Factors (JIFs), although it has been argued that these are less appropriate for practical disciplines such as nursing midwifery. In order to accurately reflect the nature of nursing and midwifery as a discipline, given the inherent flaws of using just one indicator of journal quality to assess performance overall, this project was designed to develop a tool which combined both objective and subjective methods to produce a ranking system which is specifically relevant to the disciplines of nursing and midwifery. This project succeeded in developing the Journal Evaluation Tool (JET), through extensive consultations with experts in the fields of nursing and midwifery. This tool may overcome some problems associated with the sole use of the journal impact factor, and may be utilised as an alternative measure of journal quality. The new tool was tested using a sample of 52 responding journals; and has now been disseminated to nursing and midwifery bodies in Australia and New Zealand, along with instructions for its use and recommendations for future research.

    Noise is a serious stressor affecting the health of millions of citizens. It has been suggested that disturbance by noise is responsible for a substantial part of the damage to human health. However, no recommended approach to address noise impacts was proposed by the handbook for life cycle assessment (LCA) of the European Commission, nor are characterisation factors (CFs) and appropriate inventory data available in commonly used databases. This contribution provides CFs to allow for the quantification of noise impacts on human health in the LCA framework. Noise propagation standards and international reports on acoustics and noise impacts were used to define the model parameters. Spatial data was used to calculate spatially-defined CFs in the form of 10-by-10-km maps. The results of this analysis were combined with data from the literature to select input data for representative archetypal situations of emission (e.g. urban day with a frequency of 63 Hz, rural night at 8000 Hz, etc.). A total of 32 spatial and 216 archetypal CFs were produced to evaluate noise impacts at a European level (i.e. EU27). The possibility of a user-defined characterisation factor was added to support the possibility of portraying the situation of full availability of information, as well as a highly-localised impact analysis. A Monte Carlo-based quantitative global sensitivity analysis method was applied to evaluate the importance of the input factors in determining the variance of the output. The factors produced are ready to be implemented in the available LCA databases and software. The spatial approach and archetypal approach may be combined and selected according to the amount of information available and the life cycle under study. The framework proposed and used for calculations is flexible enough to be expanded to account for impacts on target subjects other than humans and to continents other than Europe. PMID:24035845

    Although oral health-related quality of life (OHRQoL) as measured by the Oral Health Impact Profile (OHIP) is thought to be multidimensional, the nature of these dimensions is not known. The aim of this report was to explore the dimensionality of the OHIP using the Dimensions of OHRQoL (DOQ) Project, an international study of general population subjects and prosthodontic patients. Using the project's Learning Sample (n = 5173), we conducted an exploratory factor analysis on the 46 OHIP items not specifically referring to dentures for 5146 subjects with sufficiently complete data. The first eigenvalue (27·0) of the polychoric correlation matrix was more than ten times larger than the second eigenvalue (2·6), suggesting the presence of a dominant, higher-order general factor. Follow-up analyses with Horn's parallel analysis revealed a viable second-order, four-factor solution. An oblique rotation of this solution revealed four highly correlated factors that we named Oral Function, Oro-facial Pain, Oro-facial Appearance and Psychosocial Impact. These four dimensions and the strong general factor are two viable hypotheses for the factor structure of the OHIP. PMID:24909881

    One of the most important problems in studies of building environment is a description of how it is influenced by various dynamically changing factors. In this paper we characterized the joint impact of a collection of factors on indoor air quality (IAQ). We assumed that the influence is reflected in the temporal variability of IAQ parameters and may be deduced from it. The proposed method utilizes mean square displacement (MSD) analysis which was originally developed for studying the dynamics in various systems. Based on the MSD time-dependence descriptor β, we distinguished three types of the collective impact of factors on IAQ: retarding, stabilizing and promoting. We presented how the aggregated factors influence the temperature, relative humidity and CO2 concentration, as these parameters are informative for the condition of indoor air. We discovered, that during a model day there are encountered one, two or even three types of influence. The presented method allows us to study the impacts from the perspective of the dynamics of indoor air.

  1. Peer Review Quality and Transparency of the Peer-Review Process in Open Access and Subscription Journals

    2016-01-01

    Background Recent controversies highlighting substandard peer review in Open Access (OA) and traditional (subscription) journals have increased the need for authors, funders, publishers, and institutions to assure quality of peer-review in academic journals. I propose that transparency of the peer-review process may be seen as an indicator of the quality of peer-review, and develop and validate a tool enabling different stakeholders to assess transparency of the peer-review process. Methods and Findings Based on editorial guidelines and best practices, I developed a 14-item tool to rate transparency of the peer-review process on the basis of journals’ websites. In Study 1, a random sample of 231 authors of papers in 92 subscription journals in different fields rated transparency of the journals that published their work. Authors’ ratings of the transparency were positively associated with quality of the peer-review process but unrelated to journal’s impact factors. In Study 2, 20 experts on OA publishing assessed the transparency of established (non-OA) journals, OA journals categorized as being published by potential predatory publishers, and journals from the Directory of Open Access Journals (DOAJ). Results show high reliability across items (α = .91) and sufficient reliability across raters. Ratings differentiated the three types of journals well. In Study 3, academic librarians rated a random sample of 140 DOAJ journals and another 54 journals that had received a hoax paper written by Bohannon to test peer-review quality. Journals with higher transparency ratings were less likely to accept the flawed paper and showed higher impact as measured by the h5 index from Google Scholar. Conclusions The tool to assess transparency of the peer-review process at academic journals shows promising reliability and validity. The transparency of the peer-review process can be seen as an indicator of peer-review quality allowing the tool to be used to predict academic

    2011-01-01

    To address biosecurity issues, government agencies, academic institutions, and professional societies have developed policies concerning the publication of “dual-use” biomedical research—that is, research that could be readily applied to cause significant harm to the public, the environment, or national security. We conducted an e-mail survey of life science journals to determine the percentage that have a dual-use policy. Of the 155 journals that responded to our survey (response rate 39%), only 7.7% stated that they had a written dual-use policy and only 5.8% said they had experience reviewing dual-use research in the past 5 years. Among the potential predictors we investigated, the one most highly associated with a journal having a written dual-use policy was membership in the Nature Publishing Group (positive association). When considered individually, both previous experience with reviewing dual-use research and the journal's impact factor appeared to be positively associated with having a written dual-use policy, but only the former remained significant after adjusting for publishing group. Although preventing the misuse of scientific research for terrorist or criminal purposes is an important concern, few biomedical journals have dual-use review policies. Journals that are likely to review research that raises potential dual-use concerns should consider developing dual-use policies. PMID:21395429

    Maisonneuve, Hervé

    2012-09-01

    Research integrity is not negotiable, but we regularly observe research misconduct, and journals are victims or guilty. Journals do not have the objective to assess research integrity: that's the Institutions' roles. Journals discover research misconduct when articles are reviewed (an editor or a reviewer detect signals), or after the article's publication when a reader or a whistleblower call the journal. The editors and reviewers' research misconduct are less described and not publicized in the medias. The peer-review system is criticised. If authors were fair-play, and reviews well done, the journals should not publish articles containing false data. The opponents to the peer-review system propose no alternatives to replace it. The anonymous peer reviews are questioned: it has never been proved that quality of anonymous reading was better than quality of open reading. The Open Access facilitated the creation of many journals. Some journals are excellent and got an impact factor; most journals have a poor quality and don't follow the publications ethics standards. When errors and fraud are identified, journals can publish 3 statements: erratum for errors, expression of concern for errors or fraud when evidence is not established, and retraction when evidence is obvious.

    2013-01-01

    Journal policy on research data and code availability is an important part of the ongoing shift toward publishing reproducible computational science. This article extends the literature by studying journal data sharing policies by year (for both 2011 and 2012) for a referent set of 170 journals. We make a further contribution by evaluating code sharing policies, supplemental materials policies, and open access status for these 170 journals for each of 2011 and 2012. We build a predictive model of open data and code policy adoption as a function of impact factor and publisher and find higher impact journals more likely to have open data and code policies and scientific societies more likely to have open data and code policies than commercial publishers. We also find open data policies tend to lead open code policies, and we find no relationship between open data and code policies and either supplemental material policies or open access journal status. Of the journals in this study, 38% had a data policy, 22% had a code policy, and 66% had a supplemental materials policy as of June 2012. This reflects a striking one year increase of 16% in the number of data policies, a 30% increase in code policies, and a 7% increase in the number of supplemental materials policies. We introduce a new dataset to the community that categorizes data and code sharing, supplemental materials, and open access policies in 2011 and 2012 for these 170 journals. PMID:23805293

    This study takes a stratified random sample of articles published in 2014 from the top 10 journals in the disciplines of biology, chemistry, mathematics, and physics, as ranked by impact factor. Sampled articles were examined for their reporting of original data or reuse of prior data, and were coded for whether the data was publicly shared or otherwise made available to readers. Other characteristics such as the sharing of software code used for analysis and use of data citation and DOIs for data were examined. The study finds that data sharing practices are still relatively rare in these disciplines' top journals, but that the disciplines have markedly different practices. Biology top journals share original data at the highest rate, and physics top journals share at the lowest rate. Overall, the study finds that within the top journals, only 13% of articles with original data published in 2014 make the data available to others. PMID:26636676

    Turk, Nana

    2011-06-01

    Scientists from smaller countries have problems gaining visibility for their research. Does open access publishing provide a solution? Slovenia is a small country with around 5000 medical doctors, 1300 dentists and 1000 pharmacists. A search of Slovenia's Bibliographic database was carried out to identity all biomedical journals and those which are open access. Slovenia has 18 medical open access journals, but none has an impact factor and only 10 are indexed by Slovenian and international bibliographic databases. The visibility and quality of medical papers is poor. The solution might be to reduce the number of journals and encourage Slovenian scientists to publish their best articles in them. PMID:21564498

  12. The impact of environmental factors in severe psychiatric disorders

    2014-01-01

    During the last decades, schizophrenia has been regarded as a developmental disorder. The neurodevelopmental hypothesis proposes schizophrenia to be related to genetic and environmental factors leading to abnormal brain development during the pre- or postnatal period. First disease symptoms appear in early adulthood during the synaptic pruning and myelination process. Meta-analyses of structural MRI studies revealing hippocampal volume deficits in first-episode patients and in the longitudinal disease course confirm this hypothesis. Apart from the influence of risk genes in severe psychiatric disorders, environmental factors may also impact brain development during the perinatal period. Several environmental factors such as antenatal maternal virus infections, obstetric complications entailing hypoxia as common factor or stress during neurodevelopment have been identified to play a role in schizophrenia and bipolar disorder, possibly contributing to smaller hippocampal volumes. In major depression, psychosocial stress during the perinatal period or in adulthood is an important trigger. In animal studies, chronic stress or repeated administration of glucocorticoids have been shown to induce degeneration of glucocorticoid-sensitive hippocampal neurons and may contribute to the pathophysiology of affective disorders. Epigenetic mechanisms altering the chromatin structure such as histone acetylation and DNA methylation may mediate effects of environmental factors to transcriptional regulation of specific genes and be a prominent factor in gene-environmental interaction. In animal models, gene-environmental interaction should be investigated more intensely to unravel pathophysiological mechanisms. These findings may lead to new therapeutic strategies influencing epigenetic targets in severe psychiatric disorders. PMID:24574956

  13. Editorial independence at medical journals owned by professional associations: a survey of editors.

    Davis, Ronald M; Müllner, Marcus

    2002-10-01

    The purpose of this study was to assess the degree of editorial independence at a sample of medical journals and the relationship between the journals and their owners. We surveyed the editors of 33 medical journals owned by not-for-profit organizations ("associations"), including 10 journals represented on the International Committee of Medical Journal Editors (nine of which are general medical journals) and a random sample of 23 specialist journals with high impact factors that are indexed by the Institute for Scientific Information. The main outcome measures were the authority to hire, fire, and oversee the work of the editor; the editor's tenure and financial compensation; control of the journal's budget; publication of material about the association; and the editor's perceptions about editorial independence and pressure over editorial content. Of the 33 editors, 23 (70%) reported having complete editorial freedom, and the remainder reported a high level of freedom (a score of > or = 8, where 10 equals complete editorial freedom and 1 equals no editorial freedom). Nevertheless, a substantial minority of editors reported having received at least some pressure in recent years over editorial content from the association's leadership (42%), senior staff (30%), or rank-and-file members (39%). The association's board of directors has the authority to hire (48%) or fire (55%) the editor for about half of the journals, and the editor reports to the board for 10 journals (30%). Twenty-three editors (70%) are appointed for a specific term (median term = 5 years). Three-fifths of the journals have no control over their profit, and the majority of journals use the association's legal counsel and/or media relations staff. Stronger safeguards are needed to give editors protection against pressure over editorial content, including written guarantees of editorial freedom and governance structures that support those guarantees. Strong safeguards are also needed because editors

    Latin American scientists are making tremendous efforts to conduct good-quality research worthy of being published internationally. However, Colciencias, an entity created to support this research in Colombia, introduced scienciometric evaluations which had been re-evaluated elsewhere some time ago, based on measurements of aspects such as the ill-termed "impact factor". Even more serious is that the aforementioned government office is unaware that measures are based on debated mathematical principles, placing Colombian science at imminent risk of suffering from an academic yatrogeny of irreparable consequences. Therefore, an urgent restructuring of the way in which Colombia's scientific production is to be evaluated is thus mandatory before these measures have a negative impact thereon. PMID:17639682

  18. Impacts of environmental factors on fine root lifespan

    2014-01-01

    The lifespan of fast-cycling roots is a critical parameter determining a large flux of plant carbon into soil through root turnover and is a biological feature regulating the capacity of a plant to capture soil water and nutrients via root-age-related physiological processes. While the importance of root lifespan to whole-plant and ecosystem processes is increasingly recognized, robust descriptions of this dynamic process and its response to changes in climatic and edaphic factors are lacking. Here we synthesize available information and propose testable hypotheses using conceptual models to describe how changes in temperature, water, nitrogen (N), and phosphorus (P) availability impact fine root lifespan within a species. Each model is based on intrinsic responses including root physiological activity and alteration of carbohydrate allocation at the whole-plant level as well as extrinsic factors including mycorrhizal fungi and pressure from pathogens, herbivores, and other microbes. Simplifying interactions among these factors, we propose three general principles describing fine root responses to complex environmental gradients. First, increases in a factor that strongly constrains plant growth (temperature, water, N, or P) should result in increased fine root lifespan. Second, increases in a factor that exceeds plant demand or tolerance should result in decreased lifespan. Third, as multiple factors interact fine root responses should be determined by the most dominant factor controlling plant growth. Moving forward, field experiments should determine which types of species (e.g., coarse vs. fine rooted, obligate vs. facultative mycotrophs) will express greater plasticity in response to environmental gradients while ecosystem models may begin to incorporate more detailed descriptions of root lifespan and turnover. Together these efforts will improve quantitative understanding of root dynamics and help to identify areas where future research should be focused

    The journal impact factor (IF) exerts a tremendous influence on the conduct of scientists. The obsession with IF has been compared to a medical condition, sometimes referred to as "IF mania" or "impactitis." Here, we analyze the difference between impact and importance, using examples from the history of science to show that these are not equivalent. If impact does not necessarily equal importance, but scientists are focused on high-impact work, there is a danger that misuse of the IF may adversely affect scientific progress. We suggest five measures to fight this malady: (i) diversify journal club selections, (ii) do not judge science on the publication venue, (iii) reduce the reliance on journal citation metrics for employment and advancement, (iv) discuss the misuse of the IF in ethics courses, and (v) cite the most appropriate sources. If IF mania is indeed a medical condition, the most appropriate course of action may be disimpaction. PMID:26463169

    We investigate how textual properties of scientific papers relate to the number of citations they receive. Our main finding is that correlations are nonlinear and affect differently the most cited and typical papers. For instance, we find that, in most journals, short titles correlate positively with citations only for the most cited papers, whereas for typical papers, the correlation is usually negative. Our analysis of six different factors, calculated both at the title and abstract level of 4.3 million papers in over 1500 journals, reveals the number of authors, and the length and complexity of the abstract, as having the strongest (positive) influence on the number of citations.

    Hundreds of scientific journals are published in China. However, only scores of them are included in Science Citation Index by the Institute for Scientific Information, with impact factors of only 1 or less. Thus, how to establish a first-class international scientific journal in China is an important but difficult topic that deserves extensive exploration. World Journal of Gastroenterology (WJG) sets a good example although it has experienced setbacks on the road towards success. Concepts and pursuits that affirm the overall development direction, innovation and dreams that provide impetus and aspiration for higher objectives, team work and unique pattern that assure excellent quality and service, and culture and environment that also determine the speed and direction of the development, are believed to be the major factors contributing to the success of WJG. It is recommended that the effective resolution to the above issue is to learn from Chinese examples such as WJG rather than from "how foreign journals do". PMID:17109509

    To examine the impact of environmental factors on Legionella in drinking water distribution systems, the growth and survival of Legionella under various conditions was studied. When incubated in tap water at 4 °C, 25 °C, and 32 °C, L. pneumophila survival trends varied amongst the temperatures, with the stable populations maintained for months at 25 °C and 32 °C demonstrating that survival is possible at these temperatures for extended periods in oligotrophic conditions. After inoculating coupons of PVC, copper, brass, and cast iron, L. pneumophila colonized biofilms formed on each within days to a similar extent, with the exception of cast iron, which contained 1-log less Legionella after 90 days. L. pneumophila spiked in a model drinking water distribution system colonized the system within days. Chlorination of the system had a greater effect on biofilm-associated Legionella concentrations, with populations returning to pre-chlorination levels within six weeks. Biofilms sampled from drinking water meters collected from two areas within central Arizona were analyzed via PCR for the presence of Legionella. Occurrence in only one area indicates that environmental differences in water distribution systems may have an impact on the survival of Legionella. These results document the impact of different environmental conditions on the survival of Legionella in water. PMID:25996405

    Video-assisted thoracoscopic surgery (VATS) lobectomy has become a standard procedure for lung cancer treatment. Conversion-related factors and learning curve impacts, were poorly described. The aim of this study was to review the reasons and related factor for conversion in VATS lobectomy and the impact on this of the surgeon's learning curve. From June 2009 to May 2014, 154 patients who underwent a VATS lobectomy were included in our study. Patients' characteristics, pathology background, operative times, overall length of stay, overall morbidity and type of major complications were recorded for all patients and compared between non converted (n = 133) and converted (n = 21) patients. To evaluate surgeon's learning curve, we analyzed rates and causes of conversion in the first period (first 77 patients) and in the last period (78-154 patients). Patients characteristics were similar between converted and non-converted groups. Patients who were converted to open thoracotomy presented more frecuently tumors >3 cms (P = 0.02). The average of operative times and the length of stay were not significantly different between groups. Overall morbidity and major complications were also similar in both groups. There were no impact of surgeon's learning curve in overall rate conversion in both groups. Emergency conversion was always secondary to vascular accidents, all in the first group (p = 0.059). Surgeons should be expecting to perform a conversion to a thoracotomy in patients who present in preoperative studies, tumors greater than 3 cms. Learning curve only affected the emergency conversion, occurred all in the first half of our series. PMID:26561493

    A representative empirical bibliometric analysis of Russian journals included in the Journal Citation Reports-Science Edition (JCR-SE) for the time period 1995–2010 was conducted at the macro level (excluding the subject categories). It was found that the growth in the number of articles covered by JCR (a 1.8-fold increase compared to 1995) is ahead of the growth rates of Russian publications (1.2-fold increase). Hence, the share of Russian articles covered by JCR-SE was down from 2.5% in 1995 to 1.7% in 2010. It was determined that the number of articles published in an average Russian journal reduced by 20% as compared to the number of articles in an average journal of the full data set. These facts could partly shed light on the question why Russian research performance is staggering (approximately 30,000 articles per year), although the coverage of Russian journals has expanded to 150 titles. Over the past 15 years, a twofold increase in the impact factor of the Russian journals has been observed, which is higher than that for the full data set of journals (a 1.4-fold increase). Measures to improve the quality of Russian journals are proposed. PMID:24303198

    Osteoporosis is a silent disease without any evidence of disease until a fracture occurs. Approximately 200 million people in the world are affected by osteoporosis and 8.9 million fractures occur each year worldwide. Fractures of the hip are a major public health burden, by means of both social cost and health condition of the elderly because these fractures are one of the main causes of morbidity, impairment, decreased quality of life and mortality in women and men. The aim of this review is to analyze the most important factors related to the enormous impact of osteoporotic fractures on population. Among the most common risk factors, low body mass index; history of fragility fracture, environmental risk, early menopause, smoking, lack of vitamin D, endocrine disorders (for example insulin-dependent diabetes mellitus), use of glucocorticoids, excessive alcohol intake, immobility and others represented the main clinical risk factors associated with augmented risk of fragility fracture. The increasing trend of osteoporosis is accompanied by an underutilization of the available preventive strategies and only a small number of patients at high fracture risk are recognized and successively referred for therapy. This report provides analytic evidences to assess the best practices in osteoporosis management and indications for the adoption of a correct healthcare strategy to significantly reduce the osteoporosis burden. Early diagnosis is the key to resize the impact of osteoporosis on healthcare system. In this context, attention must be focused on the identification of high fracture risk among osteoporotic patients. It is necessary to increase national awareness campaigns across countries in order to reduce the osteoporotic fractures incidence. PMID:27004165

    Interest in cross-disciplinary research knowledge interchange runs high. Review processes at funding agencies, such as the U.S. National Science Foundation, consider plans to disseminate research across disciplinary bounds. Publication in the leading multidisciplinary journals, Nature and Science, may signify the epitome of successful interdisciplinary integration of research knowledge and cross-disciplinary dissemination of findings. But how interdisciplinary are they? The journals are multidisciplinary, but do the individual articles themselves draw upon multiple fields of knowledge and does their influence span disciplines? This research compares articles in three fields (Cell Biology, Physical Chemistry, and Cognitive Science) published in a leading disciplinary journal in each field to those published in Nature and Science. We find comparable degrees of interdisciplinary integration and only modest differences in cross-disciplinary diffusion. That said, though the rate of out-of-field diffusion might be comparable, the sheer reach of Nature and Science, indicated by their potent Journal Impact Factors, means that the diffusion of knowledge therein can far exceed that of leading disciplinary journals in some fields (such as Physical Chemistry and Cognitive Science in our samples).

    This study evaluated the use de standards in papers published in Brazilian and international dental journals. Papers published from January 2006 to December 2010 in the following journals were examined: Brazilian Dental Journal (BDJ), Brazilian Oral Research (BOR), Journal of Applied Oral Sciences (JAOS), Journal of Dental Research (JDR) and Dental Materials (DM). In addition to the title and type of study, issue, volume and year of publication, the following information was recorded from each paper: identification of any standard reported in the study; in case of no reported standard, indication if a standard could be used in the study. A total of 3,046 papers were examined, being 937 from DM, 936 from JDR, 489 from JAOS, 348 from BDJ, and 336 from BOR. Considering the papers that could use some standard, DM showed the highest percentage (24.9%) of reporting standards/paper, followed by JAOS (10.3%), BOR (10.1%), BDJ (6.3%) and JDR (2.4%), meaning for example that, from 936 papers examined from the JDR, 623 could use some standard but only 15 papers reported them. From all papers examined, 309 (10.1%) reported using some standard. The ISO standards were mostly reported (57.8%), followed by ASTM standards (23.7%) and 74 (18.5%) standards from other international organizations (e.g. ADA and CIE). Despite of the high impact factors of the selected dental journals, their published papers could use standards more often. This study should assist journal editors to encourage authors to consult and refer to available standards to support the scientific papers. PMID:23306220

    2016-01-01

    Objective: The primary cause of subjective tinnitus is a dysfunction of the auditory system; however, the degree of distress tinnitus causes depends largely on the psychological status of the patient. Our goal was to attempt to associate the grade of tinnitus-related distress with the psychological distress, physical, or psychological discomfort patients experienced, as well as potentially relevant social parameters, through a simultaneous analysis of these factors. Methods: We determined the level of tinnitus-related distress in 531 tinnitus patients using the German version of the tinnitus questionnaire (TQ). In addition, we used the Perceived Stress Questionnaire (PSQ); General Depression Scale Allgemeine Depression Skala (ADS), Berlin Mood Questionnaire (BSF); somatic symptoms inventory (BI), and SF-8 health survey as well as general information collected through a medical history. Results: The TQ score significantly correlated with a score obtained using PSQ, ADS, BSF, BI, and SF-8 alongside psychosocial factors such as age, gender, and marital status. The level of hearing loss and the auditory properties of the specific tinnitus combined with perceived stress and the degree of depressive mood and somatic discomfort of a patient were identified as medium-strong predictors of chronic tinnitus. Social factors such as gender, age, or marital status also had an impact on the degree of tinnitus distress. The results that were obtained were implemented in a specific cortical distress network model. Conclusions: Using a large representative sample of patients with chronic tinnitus permitted a simultaneous statistical measurement of psychometric and audiological parameters in predicting tinnitus distress. We demonstrate that single factors can be distinguished in a manner that explains their causative association and influence on the induction of tinnitus-related distress. PMID:27445776

    Bone fracture occurs in stroke patients at different times during the recovery phase, prolonging recovery time and increasing medical costs. In this review, we discuss the potential risk factors for post-stroke bone fracture and preventive methods. Most post-stroke bone fractures occur in the lower extremities, indicating fragile bones are a risk factor. Motor changes, including posture, mobility, and balance post-stroke contribute to bone loss and thus increase risk of bone fracture. Bone mineral density is a useful indicator for bone resorption, useful to identify patients at risk of post-stroke bone fracture. Calcium supplementation was previously regarded as a useful treatment during physical rehabilitation. However, recent data suggests calcium supplementation has a negative impact on atherosclerotic conditions. Vitamin D intake may prevent osteoporosis and fractures in patients with stroke. Although drugs such as teriparatide show some benefits in preventing osteoporosis, additional clinical trials are needed to determine the most effective conditions for post-stroke applications.

    Background: People with mental health problems are known to be socially excluded but the contribution of pre-morbid characteristics, symptoms and needs, and the impact on quality of life is unknown. Aims: To investigate change in social inclusion after the development of a psychotic Illness and factors associated with this. Methods: A cross-sectional community survey of people with psychosis was carried out in three areas of London. Five domains of social inclusion (social integration, consumption, access to services, productivity, political engagement) were assessed prior to the onset of illness and currently using the Social Inclusion Questionnaire User Experience. Quality of life, symptoms and needs were also assessed using standardized measures. Factors associated with change in social inclusion were investigated using multiple regression. Results: Productivity and social integration among the 67 participants reduced after the onset of psychosis. Older age at onset and longer duration of illness were associated with greater reduction in productivity. Less reduction in social integration was associated with greater quality of life. Participants reported barriers to social inclusion that were directly related to symptoms of their illness, low confidence and poor self-esteem. Conclusions: A greater focus on interventions that can facilitate the occupation and the social networks of people with psychosis is required. Interventions that tackle ‘self-stigma’ may also prove useful in mitigating the social exclusion experienced by people with psychosis. PMID:23399990

  20. Impact of HFIR LEU Conversion on Beryllium Reflector Degradation Factors

    2013-10-01

    An assessment of the impact of low enriched uranium (LEU) conversion on the factors that may cause the degradation of the beryllium reflector is performed for the High Flux Isotope Reactor (HFIR). The computational methods, models, and tools, comparisons with previous work, along with the results obtained are documented and discussed in this report. The report documents the results for the gas and neutronic poison production, and the heating in the beryllium reflector for both the highly enriched uranium (HEU) and LEU HFIR configurations, and discusses the impact that the conversion to LEU may have on these quantities. A time-averaging procedure was developed to calculate the isotopic (gas and poisons) production in reflector. The sensitivity of this approach to different approximations is gauged and documented. The results show that the gas is produced in the beryllium reflector at a total rate of 0.304 g/cycle for the HEU configuration; this rate increases by ~12% for the LEU case. The total tritium production rate in reflector is 0.098 g/cycle for the HEU core and approximately 11% higher for the LEU core. A significant increase (up to ~25%) in the neutronic poisons production in the reflector during the operation cycles is observed for the LEU core, compared to the HEU case, for regions close to the core s horizontal midplane. The poisoning level of the reflector may increase by more than two orders of magnitude during long periods of downtime. The heating rate in the reflector is estimated to be approximately 20% lower for the LEU core than for the HEU core. The decrease is due to a significantly lower contribution of the heating produced by the gamma radiation for the LEU core. Both the isotopic (gas and neutronic poisons) production and the heating rates are spatially non-uniform throughout the beryllium reflector volume. The maximum values typically occur in the removable reflector and close to the midplane.

    It is crucial to investigate how climate and management factors impact poplar plantation production and soil carbon sequestration interactively. We extracted above-ground net primary production (ANPP), climate and management factors from peer-reviewed journal articles and analyzed impact of management factor and climate on the mean annual increment (MAI) of poplar ANPP statistically. Previously validated mechanistic model (ED) is used to perform case simulations for managed poplar plantations under different harvesting rotations. The meta-analysis indicate that the dry matter MAI was 6.3 Mg ha(-1) yr(-1) (n=641, sd=4.9) globally, and 5.1 (n=292, sd=4.0), 8.1 (n=224, sd=4.7) and 4.4 Mg ha(-1) yr(-1) (n=125, sd=3.2) in Europe, the US and China, respectively. Poplar MAI showed a significant response to GDD, precipitation and planting density and formed a quadratic relationship with stand age. The low annual production for poplar globally was probably caused by suboptimal water availability, rotation length and planting density. SEM attributes the variance of poplar growth rate more to climate than to management effects. Case simulations indicated that longer rotation cycle significantly increased soil carbon storage. Findings of this work suggests that management factor of rotation cycle alone could have dramatic impact on the above ground growth, as well as on the soil carbon sequestration of poplar plantations and will be helpful to quantify the long-term carbon sequestration through short rotation plantation. The findings of this study are useful in guiding further research, policy and management decisions towards sustainable poplar plantations. PMID:26531329

    BACKGROUND: Metastatic brain tumors are a common complication of systemic cancers. Good performance status, absence of extracranial metastases, age < 65 years and control of the primary tumor are the strongest predictors of survival. Controversy exists regarding best adjuvant treatment for patients. Therefore, careful evaluation of patient features and tumor characteristics must be considered when determining treatment modality. OBJECTIVES: The aim of the study was to assess the treatment management and clinical features of metastatic brain neoplasms following a neurosurgical procedure and evaluate factors conditioning survival. METHODS: Between January 1st 2009 and January 1st 2013, medical files of patients who underwent a surgical procedure for metastatic brain tumors at Hôpital de l'Enfant-Jésus in Québec City were reviewed. Data on patient features, primary and metastatic neoplasm characteristics, procedure and survival were recorded. Wilcoxon rank sum test, Kruskal-Wallis test and Cox proportional-hazards regression for survival data were used to assess the impact of treatments and patient characteristics on survival. Efficacy of whole brain radiation therapy (WBRT), stereotactic radiosurgery (SRS) and combined treatment in terms of patient survival were also evaluated. RESULTS: One hundred and twenty six patient files were reviewed and 109 were included for analysis. The mean survival time for patients was 537.9 days. Age below 65 years (p = 0.08) was a protective factor. WBRT combined with SRS (p < 0.0001), the use of WBRT alone (p = 0.002) or SRS alone (p = 0.004) all significantly improved survival. SRS, when compared to WBRT alone or to combined WBRT and SRS treatment, did not show significant difference in survival. CONCLUSION: Survival in our population is influenced by age and the use of adjuvant treatment. The choice of treatment modality after surgery remains somewhat controversial and our results support the need for further studies to compare

    Research papers authored by Medical Physicists address a large spectrum of oncologic, imaging, or basic research problems; exploit a wide range of physical and engineering methodologies; and often describe the efforts of a multidisciplinary research team. Given the large number (about 100) competing journals accepting medical physics articles, it may not be clear to an individual author which journal is the best venue for disseminating their work to the scientific community. Relevant factors usually include the Journal’s audience and scientific impact, but also such factors as perceived acceptance rate, interest in their topic, and quality of service. The purpose of this symposium is to provide the medical physics community with an overview of scope, review processes, and article guidelines for the following journals: Medical Physics, International Journal of Radiation Biology and Physics, Journal of Applied Clinical Medical Physics, and Practical Radiation Oncology. The senior editors for each journal will provide details as to the journals review process, for example: single blind versus double blind reviews; the hierarchy of the review process in terms of editorial board structure; the reality of acceptance, in terms of acceptance rate; and the types of research the journal prefers to publish. The goal is to provide for authors guidance before they begin to write their papers, not only for proper formatting, but also that the readership is appropriate for the particular paper, hopefully increasing the likelihood of publication. Learning Objectives: To review each Journal’s submission and review process Guidance as to how to increase chances of acceptance To help decipher which journal is appropriate for a given work.

    The factors affecting patterns of benthic [seabed] biology and chemistry around 50 Scottish fish farms were investigated using linear mixed-effects models that account for inherent correlations between observations from the same farm. The abundance of benthic macrofauna and sediment concentrations of organic carbon were both influenced by a significant, albeit weak, interaction between farm size, defined as the maximum weight of fish permitted on site at any one time, and current speed. Above a farm size threshold of between 800 and 1000 t, the magnitude of effects at farms located in areas of elevated current speeds were greater than at equivalent farms located in more quiescent waters. Sediment concentrations of total organic matter were influenced by an interaction between distance and depth, indicating that wind-driven resuspension events may help reduce the accumulation of organic waste at farms located in shallow waters. The analyses presented here demonstrate that the production and subsequent fate of organic waste at fish farms is more complex than is often assumed; in isolation, current speed, water depth, and farr size are not necessarily good predictors of benthic impact.

    Background Quantitative studies are becoming more recognized as important to understanding health care with all of its richness and complexities. The purpose of this descriptive survey was to provide a quantitative evaluation of the qualitative studies published in 170 core clinical journals for 2000. Methods All identified studies that used qualitative methods were reviewed to ascertain which clinical journals publish qualitative studies and to extract research methods, content (persons and health care issues studied), and whether mixed methods (quantitative and qualitative methods) were used. Results 60 330 articles were reviewed. 355 reports of original qualitative studies and 12 systematic review articles were identified in 48 journals. Most of the journals were in the discipline of nursing. Only 4 of the most highly cited health care journals, based on ISI Science Citation Index (SCI) Impact Factors, published qualitative studies. 37 of the 355 original reports used both qualitative and quantitative (mixed) methods. Patients and non-health care settings were the most common groups of people studied. Diseases and conditions were cancer, mental health, pregnancy and childbirth, and cerebrovascular disease with many other diseases and conditions represented. Phenomenology and grounded theory were commonly used; substantial ethnography was also present. No substantial differences were noted for content or methods when articles published in all disciplines were compared with articles published in nursing titles or when studies with mixed methods were compared with studies that included only qualitative methods. Conclusions The clinical literature includes many qualitative studies although they are often published in nursing journals or journals with low SCI Impact Factor journals. Many qualitative studies incorporate both qualitative and quantitative methods. PMID:15271221
