    To determine whether methodological and reporting quality are associated with surrogate measures of publication impact in the field of dementia biomarker studies. We assessed dementia biomarker studies included in a previous systematic review in terms of methodological and reporting quality using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS) and Standards for Reporting of Diagnostic Accuracy (STARD), respectively. We extracted additional study and journal-related data from each publication to account for factors shown to be associated with impact in previous research. We explored associations between potential determinants and measures of publication impact in univariable and stepwise multivariable linear regression analyses. We aimed to collect data on four measures of publication impact: two traditional measures-average number of citations per year and 5-year impact factor of the publishing journal and two alternative measures-the Altmetric Attention Score and counts of electronic downloads. The systematic review included 142 studies. Due to limited data, Altmetric Attention Scores and electronic downloads were excluded from the analysis, leaving traditional metrics as the only analysed outcome measures. We found no relationship between QUADAS and traditional metrics. Citation rates were independently associated with 5-year journal impact factor (β=0.42; pcitation rates (β=0.45; pCitation rates and 5-year journal impact factor appear to measure different dimensions of impact. Citation rates were weakly associated with completeness of reporting, while neither traditional metric was related to methodological rigour. Our results suggest that high publication usage and journal outlet is not a guarantee of quality and readers should critically appraise all papers regardless of presumed impact. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Neuroscience and molecular biology have been generating large datasets over the past years that are reshaping how research is being conducted. In their wake, open data sharing has been singled out as a major challenge for the future of research. We conducted a comparative study of citations of data publications in both fields, showing that the average publication tagged with a data-related term by the NCBI MeSH (Medical Subject Headings) curators achieves a significantly larger citation impact than the average in either field. We introduce a new metric, the data article citation index (DAC-index), to identify the most prolific authors among those data-related publications. The study is fully reproducible from an executable Rmd (R Markdown) script together with all the citation datasets. We hope these results can encourage authors to more openly publish their data.

    Full Text Available Britton Chance was a pioneer in many scientific fields such as enzymatic reaction kinetics, bioenergetics, metabolism, in vivo NMR, and biophotonics. As an engineer, physical chemist, physicist, physiologist, biophysicist, biochemist, innovator and educator, he had worked in diversified fields over extended periods between 1926 until his death in 2010, at the age of 97. In order to illustrate his scientific career and great impact on research from a new perspective, we employ scientometric analysis tools to analyze the publications of Britton Chance with data downloaded from the ISI Citation Indexes in April 2013. We included articles, reviews and proceeding papers but excluded meeting abstracts. In total, we obtained 1023 publication records with 1236 authors in 266 journals with 17,114 citations from 1945 to 2013. We show the annual publications and citations that Britton Chance received from 1945 to 2013, and generate HistCite maps on the basis of the global citations (GCS and local (self citations (LCS to show the citation relationships among the top-30 publications of Britton Chance. Metabolism and the development of physical methods to probe it appear to be the connecting thread of the lifelong research of Britton Chance. Furthermore, we generate the journal map and co-authorship map to show the broad scope of research topics and collaborators and the high impacts of the scientific oeuvre of Britton Chance ranging from physics, engineering, chemistry and biology to medicine.

  6. A method for the automated, reliable retrieval of publication-citation records.

    Full Text Available BACKGROUND: Publication records and citation indices often are used to evaluate academic performance. For this reason, obtaining or computing them accurately is important. This can be difficult, largely due to a lack of complete knowledge of an individual's publication list and/or lack of time available to manually obtain or construct the publication-citation record. While online publication search engines have somewhat addressed these problems, using raw search results can yield inaccurate estimates of publication-citation records and citation indices. METHODOLOGY: In this paper, we present a new, automated method that produces estimates of an individual's publication-citation record from an individual's name and a set of domain-specific vocabulary that may occur in the individual's publication titles. Because this vocabulary can be harvested directly from a research web page or online (partial publication list, our method delivers an easy way to obtain estimates of a publication-citation record and the relevant citation indices. Our method works by applying a series of stringent name and content filters to the raw publication search results returned by an online publication search engine. In this paper, our method is run using Google Scholar, but the underlying filters can be easily applied to any existing publication search engine. When compared against a manually constructed data set of individuals and their publication-citation records, our method provides significant improvements over raw search results. The estimated publication-citation records returned by our method have an average sensitivity of 98% and specificity of 72% (in contrast to raw search result specificity of less than 10%. When citation indices are computed using these records, the estimated indices are within of the true value 10%, compared to raw search results which have overestimates of, on average, 75%. CONCLUSIONS: These results confirm that our method provides

    This article examines the relative positions with respect to nanotechnology research publications of the European Union (EU), the United States (US), Japan, Germany, China, and three Asian Tiger nations (South Korea, Singapore, and Taiwan). The analysis uses a dataset of nanotechnology publication records for the time period 1990 through 2006 (part year) extracted from the Science Citation Index obtained through the Web of Science and was developed through a two-stage modularized Boolean approach. The results show that although the EU and the US have the highest number of nanotechnology publications, China and other Asian countries are increasing their publications rapidly, taking an ever-larger proportion of the total. When viewed in terms of the quality-based measure of citations, Asian nanotechnology researchers also show growth in recent years. However, by such citation measures, the US still maintains a strongly dominant position, followed by the EU.

    CDS Invenio is the web-based integrated digital library system developed at CERN. It is a suite of applications which provides the framework and tools for building and managing an autonomous digital library server. Within this framework, the goal of this project is to implement new ranking methods based on the bibliographic citation graph extracted from the CDS Invenio database. As a first step, we implemented the Citation Count as a baseline ranking method. The major disadvantage of this method is that all citations are treated equally, disregarding their importance and their publication date. To overcome this drawback, we consider two different approaches: a link-based approach which extends the PageRank model to the bibliographic citation graph and a time-dependent approach which takes into account time in the citation counts. In addition, we also combined these two approaches in a hybrid model based on a time-dependent PageRank. In the present document, we describe the conceptual background behind our new...

    To evaluate the zero-citation sizes. Based on the data of the Russian Science Citation Index the publication activity of four leading institutes in the field of Psychiatry and Addiction is analyzed. The same indices in the field of Neurology were used as a control. Number and percentage of publications with ≥1 citations and zero-citation were analyzed. It has been shown that in psychiatric science zero citation rate is quite high (from 32.8% to 47.2%, an average of 42.9%). It is higher compared to the control. Zero-citation indicator is essential to evaluate the effectiveness of scientific institutions.

    The Astrophysics Source Code Library (ASCL, ascl.net), established in 1999, is a free online registry for source codes used in research that has appeared in, or been submitted to, peer-reviewed publications. The ASCL is indexed by the SAO/NASA Astrophysics Data System (ADS) and Web of Science and is citable by using the unique ascl ID assigned to each code. In addition to registering codes, the ASCL can house archive files for download and assign them DOIs. The ASCL advocations for software citation on par with article citation, participates in multidiscipinary events such as Force11, OpenCon, and the annual Workshop on Sustainable Software for Science, works with journal publishers, and organizes Special Sessions and Birds of a Feather meetings at national and international conferences such as Astronomical Data Analysis Software and Systems (ADASS), European Week of Astronomy and Space Science, and AAS meetings. In this presentation, I will discuss some of the challenges of gathering credit for publishing software and ideas and efforts from other disciplines that may be useful to astronomy.

    The impact factor (IF), as the most important criterion for journal's quality measurement, is affected by the self-citation and number of publications in each journal. To find out the relationship between the number of publications and self-citations in a journal, and their correlations with IF. Self-citations and impact factors of nine top gastroenterology and hepatology journals were assessed during the seven recent years (2005-2011) through Journal Citation Reports (JCR, ISI Thomson Reuters). Although impact factors of all journals increased during the study, five out of nine journals increased the number of publications from 2005 to 2011. There was an increase in self-citation only in the journal of HEPATOLOGY (499 in 2005 vs. 707 in 2011). Impact factors of journals (6.5 ± 3.5) were positively correlated with total number of publications (248.6 ± 91.7) (R: 0.688, P citation rate (238.73 ± 195.317) was highly correlated with total number of publications in each journal (248.6 ± 91.7) (R: 0.861, P citation (6.08 ± 3.3) had a correlation (R: 0.672, P citation have definite effects on IF of a journal and because IF is the most prominent criterion for journal's quality measurement, it would be a good idea to consider factors affecting on IF such as self-citation.

    We previously demonstrated that cardiovascular (CV) trials funded by the National Heart, Lung, and Blood Institute (NHLBI) were more likely to be published in a timely manner and receive high raw citation counts if they focused on clinical endpoints. We did not examine the metrics of trial reports, and our citation measures were limited by failure to account for topic-related citation behaviors. Of 244 CV trials completed between 2000 and 2011, we identified 184 whose main results were published by August 20, 2014. One investigator who was blinded to rapidity of publication and citation data read each publication and characterized it according to modified Delphi criteria. There were 46 trials (25%) that had Delphi scores of 8 or 9 (of a possible 9); these trials published faster (median time from trial completion to publication, 12.6 [interquartile range {IQR}, 6.7 to 23.3] vs. 21.8 [IQR, 12.1 to 34.9] months; Pcitation impact (median citation percentile for topic and date of publication, with 0 best and 100 worst, 1.92 [IQR, 0.64 to 7.83] vs. 8.41 [IQR, 1.80 to 24.75]; P=0.002). By random forest regression, we found that the 3 most important predictors of normalized citation percentile values were total costs, intention-to-treat analyses (as a modified Delphi quality measure), and focus on clinical (not surrogate) endpoints. NHLBI CV trials were more likely to publish results quickly and yield higher topic-normalized citation impact if they reported results according to well-defined metrics, along with focus on clinical endpoints. © 2015 The Authors.

    2017-02-01

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

    The purpose of this study is to determine whether study quality and completeness of reporting of systematic reviews (SR) and meta-analyses (MA) published in high impact factor (IF) radiology journals is associated with citation rates. All SR and MA published in English between Jan 2007-Dec 2011, in radiology journals with an IF >2.75, were identified on Ovid MEDLINE. The Assessing the Methodologic Quality of Systematic Reviews (AMSTAR) checklist for study quality, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist for study completeness, was applied to each SR & MA. Each SR & MA was then searched in Google Scholar to yield a citation rate. Spearman correlation coefficients were used to assess the relationship between AMSTAR and PRISMA results with citation rate. Multivariate analyses were performed to account for the effect of journal IF and journal 5-year IF on correlation with citation rate. Values were reported as medians with interquartile range (IQR) provided. 129 studies from 11 journals were included (50 SR and 79 MA). Median AMSTAR result was 8.0/11 (IQR: 5-9) and median PRISMA result was 23.0/27 (IQR: 21-25). The median citation rate for SR & MA was 0.73 citations/month post-publication (IQR: 0.40-1.17). There was a positive correlation between both AMSTAR and PRISMA results and SR & MA citation rate; ρ=0.323 (P=0.0002) and ρ=0.327 (P=0.0002) respectively. Positive correlation persisted for AMSTAR and PRISMA results after journal IF was partialed out; ρ=0.243 (P=0.006) and ρ=0.256 (P=0.004), and after journal 5-year IF was partialed out; ρ=0.235 (P=0.008) and ρ=0.243 (P=0.006) respectively. There is a positive correlation between the quality and the completeness of a reported SR or MA with citation rate which persists when adjusted for journal IF and journal 5-year IF.

Coverage of academic citation databases compared with coverage of scientific social media: personal publication lists as calibration parameters. Online Information Review 39(2: 255-264. http://dx.doi.org/10.1108/OIR-07-2014-0159 Objective – The purpose of this study was to explore coverage rates of information science publications in academic citation databases and scientific social media using a new method of personal publication lists as a calibration parameter. The research questions were: How many publications are covered in different databases, which has the best coverage, and what institutions are represented and how does the language of the publication play a role? Design – Bibliometric analysis. Setting – Academic citation databases (Web of Science, Scopus, Google Scholar and scientific social media (Mendeley, CiteULike, Bibsonomy. Subjects – 1,017 library and information science publications produced by 76 information scientists at 5 German-speaking universities in Germany and Austria. Methods – Only documents which were published between 1 January 2003 and 31 December 2012 were included. In that time the 76 information scientists had produced 1,017 documents. The information scientists confirmed that their publication lists were complete and these served as the calibration parameter for the study. The citations from the publication lists were searched in three academic databases: Google Scholar, Web of Science (WoS, and Scopus; as well as three social media citation sites: Mendeley, CiteULike, and BibSonomy and the results were compared. The publications were searched for by author name and words from the title. Main results – None of the databases investigated had 100% coverage. In the academic databases, Google Scholar had the highest amount of coverage with an average of 63%, Scopus an average of 31%, and

    We examined the impact of work presented in the plenary sessions at the meeting of The American Association for Thoracic Surgery (AATS), by determining how frequently the published papers corresponding to the session presentations during the past 20 years, were cited; those that were most cited were identified. We reviewed the AATS meeting programs from the 20-year period from 1994 to 2014 and identified the corresponding publications in the Journal of Thoracic and Cardiovascular Surgery (JTCVS) from all abstracts presented at the plenary sessions. Papers were categorized as cardiac, thoracic, or congenital. References were evaluated for subsequent citation in the Web of Science (WoS), and Google Scholar (GS). We determined both the median number of citations overall, and per year. For comparison, we evaluated numbers of citations in WoS from current JTCVS papers in issues containing the 3 most-cited plenary session papers. Among 195 published plenary papers, the median number of citations in WoS and GS was 49 and 76, respectively. The median total number of citations in WoS was as follows: 51 for cardiac-category papers (n = 105); 61 for thoracic (n = 55), and 41 for congenital (n = 35). These values were higher than the median total number of citations for contemporary nonplenary JTCVS papers: cardiac (22, n = 55; P papers published in JTCVS. The median number of citations per year since publication for plenary publications was 5.9 (cardiac), 6 (thoracic), and 3.7 (congenital), respectively. Publications corresponding to the plenary sessions of the AATS are highly cited and include some of the seminal studies in our field in the past 20 years.

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

  20. Missing citations due to exact reference matching: Analysis of a random sample from WoS. Are publications from peripheral countries disadvantaged?

    Donner, P.

    2016-07-01

    Citation counts of scientific research contributions are one fundamental data in scientometrics. Accuracy and completeness of citation links are therefore crucial data quality issues (Moed, 2005, Ch. 13). However, despite the known flaws of reference matching algorithms, usually no attempts are made to incorporate uncertainty about citation counts into indicators. This study is a step towards that goal. Particular attention is paid to the question whether publications from countries not using basic Latin script are differently affected by missed citations. The proprietary reference matching procedure of Web of Science (WoS) is based on (near) exact agreement of cited reference data (normalized during processing) to the target papers bibliographical data. Consequently, the procedure has near-optimal precision but incomplete recall - it is known to miss some slightly inaccurate reference links (Olensky, 2015). However, there has been no attempt so far to estimate the rate of missed citations by a principled method for a random sample. For this study a simple random sample of WoS source papers was drawn and it was attempted to find all reference strings of WoS indexed documents that refer to them, in particular inexact matches. The objective is to give a statistical estimate of the proportion of missed citations and to describe the relationship of the number of found citations to the number of missed citations, i.e. the conditional error distribution. The empirical error distribution is statistically analyzed and modelled. (Author)

    Full Text Available According to the European patent agency, 15% of the references in the patent search reports are so-called non-patent literature (NPL, which refer to scientific publications not related to the patents. An included overview of research proves that a high level of NPL citation indicates a research intensity of technical solutions proposed by the patent. There has been evaluated the level of citation of Russian scientific publications, indexed in Scopus, in patent documents with cross-country comparisons. It has shown by the indicator «number of citations of national publications patents» Russian Federation is almost 87 times inferior to the United States and more than ten times worse than the performance of Japan, China, and Germany. The indicator «number of citations in patents per 1,000 publications» for Russia is (4,9 less than for Turkish (5,4, Argentine (8,5, Mexican (7,0 and South African publications (7,6. Publications of Qatar, Saudi Arabia, and Egypt also have a substantially higher value of this indicator: with 8,0 to 15,3 and 9,5, respectively.

  2. Does the DHET research output subsidy model penalise high-citation publication? A case study

    Directory of Open Access Journals (Sweden)

    Yolande X. Harley

    2016-05-01

    Full Text Available South African universities are awarded annual subsidy from the Department of Higher Education and Training (DHET based on their research publication output. Journal article subsidy is based on the number of research publications in DHET-approved journals as well as the proportional contribution of authors from the university. Co-authorship with other institutions reduces the subsidy received by a university, which may be a disincentive to collaboration. Inter-institutional collaboration may affect the scientific impact of resulting publications, as indicated by the number of citations received. We analysed 812 journal articles published in 2011 by authors from the University of Cape Town’s Faculty of Health Sciences to determine if there was a significant relationship between subsidy units received and (1 citation count and (2 field-weighted citation impact. We found that subsidy units had a significant inverse relationship with both citation count (r= -0.247; CI = -0.311 – -0.182; p"less than"0.0001 and field-weighted citation impact (r= -0.192; CI= -0.258 – -0.125; p"less than"0.0001. These findings suggest that the annual subsidy awarded to universities for research output may inadvertently penalise high-citation publication. Revision of the funding model to address this possibility would better align DHET funding allocation with the strategic plans of the South African Department of Science and Technology, the National Research Foundation and the South African Medical Research Council, and may better support publication of greater impact research.

  3. DOIs for Data: Progress in Data Citation and Publication in the Geosciences

    2012-12-01

    Identifiers for data are the bedrock on which data citation and publication rests. These, in their turn, are widely proposed as methods for encouraging researchers to share their datasets, and at the same time receive academic credit for their efforts in producing them. However, neither data citation nor publication can be properly achieved without a method of identifying clearly what is, and what isn't, part of the dataset. Once a dataset becomes part of the scientific record (either through formal data publication or through being cited) then issues such as dataset stability and permanence become vital to address. In the geosciences, several projects in the UK are concentrating on issues of dataset identification, citation and publication. The UK's Natural Environment Research Council's (NERC) Science Information Strategy data citation and publication project is addressing the issue of identifiers for data, stability, transparency, and credit for data producers through data citation. At a data publication level, 2012 has seen the launch of the new Wiley title Geoscience Data Journal and the PREPARDE (Peer Review for Publication & Accreditation of Research Data in the Earth sciences) project, both aiming to encourage data publication by addressing issues such as data paper submission workflows and the scientific peer-review of data. All of these initiatives work with a range of partners including academic institutions, learned societies, data centers and commercial publishers, both nationally and internationally, with a cross-project aim of developing the mechanisms so data can be identified, cited and published with confidence. This involves investigating barriers and drivers to data publishing and sharing, peer review, and re-use of geoscientific datasets, and specifically such topics as dataset requirements for citation, workflows for dataset ingestion into data centers and publishers, procedures and policies for editors, reviewers and authors of data

    This study examines the determinants of citation success among authors who have recently published their work in economic history journals. Besides offering clues about how to improve one's scientific impact, our citation analysis also sheds light on the state of the field of economic history...... find similar patterns when assessing the same authors' citation success in economics journals. As a novel feature, we demonstrate that the diffusion of research — publication of working papers, as well as conference and workshop presentations — has a first-order positive impact on the citation rate........ Consistent with our expectations, we find that full professors, authors appointed at economics and history departments, and authors working in Anglo-Saxon and German countries are more likely to receive citations than other scholars. Long and co-authored articles are also a factor for citation success. We...

    The aim of this study was to describe the research output and citation rates (academic impact) of public health dissemination and implementation research according to research design and study type. A cross sectional bibliographic study was undertaken in 2013. All original data-based studies and review articles focusing on dissemination and implementation research that had been published in 10 randomly selected public health journals in 2008 were audited. The electronic database 'Scopus' was used to calculate 5-year citation rates for all included publications. Of the 1648 publications examined, 216 were original data-based research or literature reviews focusing on dissemination and implementation research. Of these 72% were classified as descriptive/epidemiological, 26% were intervention and just 1.9% were measurement research. Cross-sectional studies were the most common study design (47%). Reviews, randomized trials, non-randomized trials and decision/cost-effectiveness studies each represented between 6 and 10% of all output. Systematic reviews, randomized controlled trials and cohort studies were the most frequently cited study designs. The study suggests that publications that had the greatest academic impact (highest citation rates) made up only a small proportion of overall public health dissemination and implementation research output.

    We previously demonstrated absence of association between peer-review-derived percentile ranking and raw citation impact in a large cohort of National Heart, Lung, and Blood Institute cardiovascular R01 grants, but we did not consider pregrant investigator publication productivity. We also did not normalize citation counts for scientific field, type of article, and year of publication. To determine whether measures of investigator prior productivity predict a grant's subsequent scientific impact as measured by normalized citation metrics. We identified 1492 investigator-initiated de novo National Heart, Lung, and Blood Institute R01 grant applications funded between 2001 and 2008 and linked the publications from these grants to their InCites (Thompson Reuters) citation record. InCites provides a normalized citation count for each publication stratifying by year of publication, type of publication, and field of science. The coprimary end points for this analysis were the normalized citation impact per million dollars allocated and the number of publications per grant that has normalized citation rate in the top decile per million dollars allocated (top 10% articles). Prior productivity measures included the number of National Heart, Lung, and Blood Institute-supported publications each principal investigator published in the 5 years before grant review and the corresponding prior normalized citation impact score. After accounting for potential confounders, there was no association between peer-review percentile ranking and bibliometric end points (all adjusted P>0.5). However, prior productivity was predictive (Pcitation counts, we confirmed a lack of association between peer-review grant percentile ranking and grant citation impact.

    Clustering methods are applied regularly in the bibliometric literature to identify research areas or scientific fields. These methods are for instance used to group publications into clusters based on their relations in a citation network. In the network science literature, many clustering methods, often referred to as graph partitioning or community detection techniques, have been developed. Focusing on the problem of clustering the publications in a citation network, we present a systematic comparison of the performance of a large number of these clustering methods. Using a number of different citation networks, some of them relatively small and others very large, we extensively study the statistical properties of the results provided by different methods. In addition, we also carry out an expert-based assessment of the results produced by different methods. The expert-based assessment focuses on publications in the field of scientometrics. Our findings seem to indicate that there is a trade-off between different properties that may be considered desirable for a good clustering of publications. Overall, map equation methods appear to perform best in our analysis, suggesting that these methods deserve more attention from the bibliometric community.

  16. An approach for the condensed presentation of intuitive citation impact metrics which remain reliable with very few publications

    2016-07-01

    An approach for presenting citation data in a condensed and intuitive manner which will allow for their reliable interpretation by policy analysts even in cases where the number of peer-reviewed publications produced by a given entity remains small is presented. The approach is described using country level data in Agronomy & Agriculture (2004–2013), an area of specialisation for many developing countries with a small output size. Four citation impact metrics, and a synthesis graph that we call the distributional micro-charts of relative citation counts, are considered in building our “preferred” presentation layout. These metrics include two indicators that have long been used by Science-Metrix in its bibliometric reports, the Average of Relative Citations (ARC) and the percentage of publications in the 10% most cited publications in the database (HCP), as well as two newer metrics, the Median of Relative Citations (MRC) and the Relative Integration Score (RIS). The findings reveal that the proposed approach combining the MRC and HCP with the distributional micro-charts effectively allows to better qualify the citation impact of entities in terms of central location, density of the upper citation tail and overall distribution than Science-Metrix former approach based on the ARC and HCP. This is especially true of cases with small population sizes where a strong presence of outliers (denoted by strong HCP scores) can have a significant effect on the central location of the citation data when estimated with an average.

    2015-09-01

    The objectives of the present study are to examine the publication metrics of dental journals and to delineate the role of self citations in determining the impact factor of journals. The Journal Citation Reports database was used. All dental journals that had an impact factor assigned for year 2013 were selected. The outcomes were Impact Factor (IF), Eigenfactor™ (EF), article influence score (AIS), and proportion of self-citations to total citations. Independent variables were geographic region of journal and ranking of journal (based on IF). Non-parametric tests were used to examine the associations between outcomes and independent variables. During the year 2013, 82 journals in dentistry had an IF. Mean IF was 1.489 and mean IF without including self-citations was 1.231. Mean EF scores and AIS were .00458 and .5141 respectively. Mean percentage of self cites to total citations for all dental journals was 12.24%. Higher ranking journals were associated with significantly higher EF and AIS. Journals published in USA/Canada or Europe were associated with higher IF and EF compared to those published in other regions. There were no differences in percentages of self citations to total citations either across journal rankings or geographic region. Top ranking journals tend to have higher IFs due to higher EF and AIS rather than by self-citations. Self-citations increase the impact factors of dental journals by 21%. There was no geographic influence in the percentage of self-citations to total citations thus indicating a healthy dental scientific publishing environment. Copyright © 2015 Elsevier Inc.

    To draw on data about publication patterns and citation indicators of Asian Pacific Journal of Tropical Medicine (APJTM) during 2008 and June 2014 in order to know about the current state of the journal. Data used in this study were collected based on publications in APJTM from 2008 to June, 2014. Information including publication issue, type of manuscript, country/region of Corresponding author, funded research paper, and international collaboration were aggregated and analyzed with Excel software. Citation indicators including total cites, average cites of each manuscript, h-index, and impact factors were primarily drawn from Web of Science™ database on June 15, 2014 and changes over the past six and half years were interpreted. The top 10 most cited papers in Web of Science™ database were also analyzed. Number of all submissions has arisen from less than 200 in 2008 to over 1 500 in 2013, manuscript acceptance rate has decreased to be less than 14.00% indicating its improvement in quality over this period of time. Out of the 1 115 publiations, 23.77% were fruits of funded projects or produced by funded co-authors, 87.08% of all publications in APJTM were submited by authors from 10 most contributed countries. During the studied period, each published manuscript in the journal has received an average of 1.05 cites, and at least 10 publications has been cited for more 10 times. Detailed analysis shows APJTM has made great progress over the past six and half years, but authors' originating countries are still disproportionate. Efforts should be made to improve its citation indicators. Copyright © 2014 Hainan Medical College. Published by Elsevier B.V. All rights reserved.

  19. Quantitative evaluation of gender bias in astronomical publications from citation counts

    Science.gov (United States)

    2017-06-01

    Numerous studies across different research fields have shown that both male and female referees consistently give higher scores to work done by men than to identical work done by women 1,2,3 . In addition, women are under-represented in prestigious publications and authorship positions 4,5 and women receive ~10% fewer citations 6,7 . In astronomy, similar biases have been measured in conference participation 8,9 and success rates for telescope proposals 10,11 . Even though the number of doctorate degrees awarded to women is constantly increasing, women still tend to be under-represented in faculty positions 12 . Spurred by these findings, we measure the role of gender in the number of citations that papers receive in astronomy. To account for the fact that the properties of papers written by men and women differ intrinsically, we use a random forest algorithm to control for the non-gender-specific properties of these papers. Here we show that papers authored by women receive 10.4 ± 0.9% fewer citations than would be expected if the papers with the same non-gender-specific properties were written by men.

    The authors evaluated publication and citation patterns for articles supported by Clinical and Translational Science Awards (CTSA) hub investment over the first decade of the CTSA program. The aim was to elucidate a pivotal step in the translational process by providing an account of how time, hub maturity, and hub attributes were related to productivity and influence in the academic literature. In early 2017, the authors collected bibliometric data from PubMed, Web of Science InCites, and NIH iCite for articles citing any CTSA hub grants published from hub inception through 2016. They compiled data on publication and citation rates, and indices of relative citation impact aggregated by hub funding year cohort. They compared hub-level bibliometric activity by multi- versus single-institution structure and total monetary award sums, compiled from NIH RePORTER. From 2006-2016, CTSA hubs supported over 66,000 publications, with publication rates accelerating as hubs matured. These publications accumulated over 1.2 million citations, with some articles cited over 1,000 times. Indices of relative citation impact indicated that CTSA-supported publications were cited more than twice as often as expected for articles of their publication years and disciplines. Multi-institutional hubs and those awarded higher grant sums exhibited significantly higher publication and citation activity. The CTSA program is yielding a robust and growing body of influential research findings with consistently high indices of relative citation impact. Preliminary evidence suggests multi-institutional collaborations and more monetary resources are associated with elevated bibliometric activity, and therefore, may be worth their investment.

    To examine how effectively forwards citation searching with Web of Science (WOS) or Google Scholar (GS) identified evidence to support public health guidance published by the National Institute for Health and Care Excellence. Forwards citation searching was performed using GS on a base set of 46 publications and replicated using WOS. WOS and GS were compared in terms of recall; precision; number needed to read (NNR); administrative time and costs; and screening time and costs. Outcomes for all publications were compared with those for a subset of highly important publications. The searches identified 43 relevant publications. The WOS process had 86.05% recall and 1.58% precision. The GS process had 90.7% recall and 1.62% precision. The NNR to identify one relevant publication was 63.3 with WOS and 61.72 with GS. There were nine highly important publications. WOS had 100% recall, 0.38% precision and NNR of 260.22. GS had 88.89% recall, 0.33% precision and NNR of 300.88. Administering the WOS results took 4 h and cost £88-£136, compared with 75 h and £1650-£2550 with GS. WOS is recommended over GS, as citation searching was more effective, while the administrative and screening times and costs were lower. Copyright © 2015 John Wiley & Sons, Ltd.

    Full Text Available Background: Higher Education Institutions (HEIs need to ensure that the education provided meets the student’s and employer’s requirements, for today and the future. However, in addition to the challenges of teaching and learning, internationalisation, globalisation and world university rankings are rearing their heads thus increasing the demands made on many HEIs. Objective: One of the ways in which HEIs can make their mark is through world university rankings. This may be achieved by exposing more information on new and innovative research knowledge to the broader community in the global market via research publications that attract citations on open access platforms, hence influencing the university’s ranking. For this purpose and intent, a ‘simple’ and ‘easy-to-use’ online web tool was developed at a HEI. The aim was to have research publications submitted via the Online Research Output Submission System (OROSS tool, screened and deposited in the institution’s open access database. Method: Training was provided to the relevant participants and a survey was conducted to ascertain the participants’ perceptions about the utilisation of the OROSS tool and the training provided. Conclusion: This article reflects on the pilot phase of a longitudinal study. Results of an evaluation conducted by the researcher of the OROSS application from a user perspective (process are highlighted. In general, users rated OROSS favourably in terms of it being a useful, simple and easy-to-use web-based tool. The findings of this study may assist University of Johannesburg’s executive management in deciding the fate of the OROSS tool for future use.

  6. The assessment of science: the relative merits of post-publication review, the impact factor, and the number of citations.

    Science.gov (United States)

    Eyre-Walker, Adam; Stoletzki, Nina

    2013-10-01

    The assessment of scientific publications is an integral part of the scientific process. Here we investigate three methods of assessing the merit of a scientific paper: subjective post-publication peer review, the number of citations gained by a paper, and the impact factor of the journal in which the article was published. We investigate these methods using two datasets in which subjective post-publication assessments of scientific publications have been made by experts. We find that there are moderate, but statistically significant, correlations between assessor scores, when two assessors have rated the same paper, and between assessor score and the number of citations a paper accrues. However, we show that assessor score depends strongly on the journal in which the paper is published, and that assessors tend to over-rate papers published in journals with high impact factors. If we control for this bias, we find that the correlation between assessor scores and between assessor score and the number of citations is weak, suggesting that scientists have little ability to judge either the intrinsic merit of a paper or its likely impact. We also show that the number of citations a paper receives is an extremely error-prone measure of scientific merit. Finally, we argue that the impact factor is likely to be a poor measure of merit, since it depends on subjective assessment. We conclude that the three measures of scientific merit considered here are poor; in particular subjective assessments are an error-prone, biased, and expensive method by which to assess merit. We argue that the impact factor may be the most satisfactory of the methods we have considered, since it is a form of pre-publication review. However, we emphasise that it is likely to be a very error-prone measure of merit that is qualitative, not quantitative.

    2010-01-01

    Invenio is the web-based integrated digital library system developed at CERN. Within this framework, we present four types of ranking models based on the citation graph that complement the simple approach based on citation counts: time-dependent citation counts, a relevancy ranking which extends the PageRank model, a time-dependent ranking which combines the freshness of citations with PageRank and a ranking that takes into consideration the external citations. We present our analysis and results obtained on two main data sets: Inspire and CERN Document Server. Our main contributions are: (i) a study of the currently available ranking methods based on the citation graph; (ii) the development of new ranking methods that correct some of the identified limitations of the current methods such as treating all citations of equal importance, not taking time into account or considering the citation graph complete; (iii) a detailed study of the key parameters for these ranking methods.

    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).

    In this study, we investigate whether university department size is important in determining publication productivity and citation impact. Drawing on a unique dataset containing a variety of different variables at department levels, we are able to provide a richer picture of the research performance than what typically has been the case in many previous studies. In addition to analyzing the basic question of how size relates to scientific performance, we address whether the funding profile of the departments plays a role, whether the scientific performance is influenced by the composition of the academic personnel (in terms of gender, academic positions, recruiting personnel and the share of doctoral degree holders). The study shows that virtually no size effect can be identified and highly productive and highly cited units are found among both small, medium and large departments. For none of the organizational variables we are able to identify statistically significant relationships in respect to research performance at an overall level. We conclude that the productivity and citation differences at the level of departments cannot generally be explained by the selected variables for department size, funding structure and the composition of scientific personnel.

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

    The objective of this study was to analyze quantity, assess quality, and investigate international collaboration in research from Arab countries in the field of public, environmental and occupational health. Original scientific articles and reviews published from the 22 Arab countries in the category "public, environmental & occupational health" during the study period (1900 - 2012) were screened using the ISI Web of Science database. The total number of original and review research articles published in the category of "public, environmental & occupational health" from Arab countries was 4673. Main area of research was tropical medicine (1862; 39.85%). Egypt with 1200 documents (25.86%) ranked first in quantity and ranked first in quality of publications (h-index = 51). The study identified 2036 (43.57%) documents with international collaboration. Arab countries actively collaborated with authors in Western Europe (22.91%) and North America (21.04%). Most of the documents (79.9%) were published in public health related journals while 21% of the documents were published in journals pertaining to prevention medicine, environmental, occupational health and epidemiology. Research in public, environmental and occupational health in Arab countries is in the rise. Public health research was dominant while environmental and occupation health research was relatively low. International collaboration was a good tool for increasing research quantity and quality.

    Citation is one of the important metrics that are used in measuring the relevance and the impact of research publications. The potentials of citation analytics may be exploited to understand the gains of publishing scholarly peer-reviewed research outputs in either Open Access (OA) sources or Subscription-Based (SB) sources in the bid to increase citation impact. However, relevant data required for such comparative analysis must be freely accessible for evidence-based findings and conclusions. In this data article, citation scores ( CiteScores ) of 2542 OA sources and 15,040 SB sources indexed in Scopus from 2014 to 2016 were presented and analyzed based on a set of five inclusion criteria. A robust dataset, which contains the CiteScores of OA and SB publication sources included, is attached as supplementary material to this data article to facilitate further reuse. Descriptive statistics and frequency distributions of OA CiteScores and SB CiteScores are presented in tables. Boxplot representations and scatter plots are provided to show the statistical distributions of OA CiteScores and SB CiteScores across the three sub-categories (Book Series, Journal, and Trade Journal). Correlation coefficient and p-value matrices are made available within the data article. In addition, Probability Density Functions (PDFs) and Cumulative Distribution Functions (CDFs) of OA CiteScores and SB CiteScores are computed and the results are presented using tables and graphs. Furthermore, Analysis of Variance (ANOVA) and multiple comparison post-hoc tests are conducted to understand the statistical difference (and its significance, if any) in the citation impact of OA publication sources and SB publication source based on CiteScore . In the long run, the data provided in this article will help policy makers and researchers in Higher Education Institutions (HEIs) to identify the appropriate publication source type and category for dissemination of scholarly research findings with

    2011-01-01

    Citation distributions are crucial for the analysis and modeling of the activity of scientists. We investigated bibliometric data of papers published in journals of the American Physical Society, searching for the type of function which best describes the observed citation distributions. We used the goodness of fit with Kolmogorov-Smirnov statistics for three classes of functions: log-normal, simple power law and shifted power law. The shifted power law turns out to be the most reliable hypothesis for all citation networks we derived, which correspond to different time spans. We find that citation dynamics is characterized by bursts, usually occurring within a few years since publication of a paper, and the burst size spans several orders of magnitude. We also investigated the microscopic mechanisms for the evolution of citation networks, by proposing a linear preferential attachment with time dependent initial attractiveness. The model successfully reproduces the empirical citation distributions and accounts for the presence of citation bursts as well. PMID:21966387

    The paper analyzes the level of coverage and citation of publications by mechanicians of the National Academy of Sciences of Ukraine (NASU) in the Scopus database. Two groups of mechanicians are considered. One group includes 66 doctors of sciences of the S. P. Timoshenko Institute of Mechanics as representatives of the oldest institute of the NASU. The other group includes 34 members (academicians and corresponding members) of the Division of Mechanics of the NASU as representatives of the authoritative community of mechanicians in Ukraine. The results are presented for each scientist in the form of two indices—the total number of publications accessible in the database as the level of coverage of the scientist's publications in this database and the h-index as the citation level of these publications. This paper may be considered to continue the papers [6-12] published in Prikladnaya Mekhanika (International Applied Mechanics) in 2005-2009

    Full Text Available Bibliometrics deals with the quantitative analysis of some distinct characteristics (i.e. authorship, subject, publication information, and cited sources of publications or documents. The process of scientific communication in various fields can be investigated using bibliometric data obtained in such studies. This paper analyzes the bibliometric features of 100 master’s and doctoral dissertations completed at the Department of Library Science of Hacettepe University between 1974 and 2002. An average dissertation was 171 pages long and contained 70 citations. Doctoral dissertations were twice as long as master’s dissertations (275 pages as opposed to 142 pages. Similarly, the average number of citations in a doctoral dissertation was 2.5 times higher than that of a master’s dissertation. Monographs received half of all citations (7019 while journals did 42%, dissertations and electronic publications 3% each, and “other” documents such as unpublished manuscripts 2%. The Türk Kütüphaneciliği (the journal Turkish Librarianship, Resmî Gazete (Official Gazette, College & Research Libraries, Library Trends, Library Journal, Journal of the American Society for Information Science and Unesco Bulletin for Libraries were among the most frequently cited journals. Articles that appeared in the top four and top 38 journals received 32% and 67% of all citations, respectively. The distribution of citations to foreign journals fits the Bradford’s Law of Scattering. The mean half-life of sources cited in dissertations was 9 years. Sources cited in master’s dissertations were younger than those of doctoral dissertations. The great majority of cited resources in dissertations had single authorship. Findings obtained in this study can be used to evaluate the library collections as well as to develop a core journals list in librarianship.

    Full Text Available The Southampton chemical information group had its genesis in 2001, when we began an e-Science pilot project to investigate structure-property mapping, combinatorial chemistry, and the Grid. CombeChem instigated a range of activities that have since been underway for more than ten years, in many ways matching the expansion of interest in using the Web as a vehicle for collection, curation, dissemination, reuse, and exploitation of scientific data and information. Chemistry has frequently provided the exemplar case studies, notably for the series of projects – funded by Jisc and EPSRC – that investigated the issues associated with the long-term preservation of data to support the scholarly knowledge cycle, such as the eBank UK project. Rapid developments in Internet access and mobile technology have significantly influenced the way researchers view connectivity, data standards, and the increasing importance and power of semantics and the Semantic Web. These technical advances interact strongly with the social dimension and have led to a reconsideration of the responsibilities of researchers for the quality of their research and for satisfying the requirements of modern stakeholders. Such obligations have given rise to discussions about Open Access and Open Data, creating a range of alternatives that are now technically feasible but need to be socially acceptable. Business plans are changing too, but in a strange contradiction, desire can run ahead of what is possible, sensible, and affordable, while lagging behind in imagination of what would be technically possible and potentially game-changing! Taking the chemical sciences as our example and focusing on the curation of research data, we explore from our perspective, ten years back and ten years forward, how far we have been able to re-imagine the data/information value pathway from bench to publication. We assess not only the major advances and changes that have been achieved, but also

  10. Aberration of the Citation.

    2016-01-01

    Multiple inherent biases related to different citation practices (for e.g., self-citations, negative citations, wrong citations, multi-authorship-biased citations, honorary citations, circumstantial citations, discriminatory citations, selective and arbitrary citations, etc.) make citation-based bibliometrics strongly flawed and defective measures. A paper can be highly cited for a while (for e.g., under circumstantial or transitional knowledge), but years later it may appear that its findings, paradigms, or theories were untrue or invalid anymore. By contrast, a paper may remain shelved or overlooked for years or decades, but new studies or discoveries may actualize its subject at any moment. As citation-based metrics are transformed into "commercial activities," the "citation credit" should be considered on a commercial basis too, in the sense that "citation credit" should be shared out as a "citation dividend" by shareholders (coauthors) averagely or proportionally to their contributions but not fully appropriated by each of them. At equal numbers of citations, the greater number of authors, the lower "citation credit" should be and vice versa. Overlooking the presence of distorted and subjective citation practices makes many people and administrators "obsessed" with the number of citations to such an extent to run after "highly cited" authors and to create specialized citation databases for commercial purposes. Citation-based bibliometrics, however, are unreliable and unscientific measures; citation counts do not mean that a more cited work is of a higher quality or accuracy than a less cited work because citations do not measure the quality or accuracy. Citations do not mean that a highly cited author or journal is more commendable than a less cited author or journal. Citations are not more than countable numbers: no more, no less.

    2016-06-01

    Full Text Available Publication venues play an important role in the scholarly communication process. The number of publication venues has been increasing yearly, making it difficult for researchers to determine the most suitable venue for their publication. Most existing methods use citation count as the metric to measure the reputation of publication venues. However, this does not take into account the quality of citations. Therefore, it is vital to have a publication venue quality estimation mechanism. The ultimate goal of this research project is to develop a novel approach for ranking publication venues by considering publication history. The main aim of this research work is to propose a mechanism to identify the key Computer Science journals and conferences from various fields of research. Our approach is completely based on the citation network represented by publications. A modified version of the PageRank algorithm is used to compute the ranking scores for each publication. In our publication ranking method, there are many aspects that contribute to the importance of a publication, including the number of citations, the rating of the citing publications, the time metric and the authors’ reputation. Known publication venue scores have been formulated by using the scores of the publications. New publication venue ranking is taken care by the scores of Program Committee members which derive from their ranking scores as authors. Experimental results show that our publication ranking method reduces the bias against more recent publications, while also providing a more accurate way to determine publication quality.

  18. The Association between Four Citation Metrics and Peer Rankings of Research Influence of Australian Researchers in Six Fields of Public Health

    Derrick, Gemma Elizabeth; Haynes, Abby; Chapman, Simon; Hall, Wayne D.

    2011-01-01

    Doubt about the relevance, appropriateness and transparency of peer review has promoted the use of citation metrics as a viable adjunct or alternative in the assessment of research impact. It is also commonly acknowledged that research metrics will not replace peer review unless they are shown to correspond with the assessment of peers. This paper evaluates the relationship between researchers' influence as evaluated by their peers and various citation metrics representing different aspects of research output in 6 fields of public health in Australia. For four fields, the results showed a modest positive correlation between different research metrics and peer assessments of research influence. However, for two fields, tobacco and injury, negative or no correlations were found. This suggests a peer understanding of research influence within these fields differed from visibility in the mainstream, peer-reviewed scientific literature. This research therefore recommends the use of both peer review and metrics in a combined approach in assessing research influence. Future research evaluation frameworks intent on incorporating metrics should first analyse each field closely to determine what measures of research influence are valued highly by members of that research community. This will aid the development of comprehensive and relevant frameworks with which to fairly and transparently distribute research funds or approve promotion applications. PMID:21494691

    Doubt about the relevance, appropriateness and transparency of peer review has promoted the use of citation metrics as a viable adjunct or alternative in the assessment of research impact. It is also commonly acknowledged that research metrics will not replace peer review unless they are shown to correspond with the assessment of peers. This paper evaluates the relationship between researchers' influence as evaluated by their peers and various citation metrics representing different aspects of research output in 6 fields of public health in Australia. For four fields, the results showed a modest positive correlation between different research metrics and peer assessments of research influence. However, for two fields, tobacco and injury, negative or no correlations were found. This suggests a peer understanding of research influence within these fields differed from visibility in the mainstream, peer-reviewed scientific literature. This research therefore recommends the use of both peer review and metrics in a combined approach in assessing research influence. Future research evaluation frameworks intent on incorporating metrics should first analyse each field closely to determine what measures of research influence are valued highly by members of that research community. This will aid the development of comprehensive and relevant frameworks with which to fairly and transparently distribute research funds or approve promotion applications.

  1. Citation success of different publication types: a case study on all references in psychology publications from the German-speaking countries (D-A-CH-L-L) in 2009, 2010, and 2011.

    Scientometric data on the citation success of different publication types and publication genres in psychology publications are presented. Data refer to references that are cited in these scientific publications and that are documented in PSYNDEX, the exhaustive database of psychology publications from the German-speaking countries either published in German or in English language. Firstly, data analyses refer to the references that are cited in publications of 2009 versus 2010 versus 2011. With reference to all cited references, the portion of journal articles ranges from 57 to 61 %, of books from 22 to 24 %, and of book chapters from 14 to 15 %, with a rather high stability across the three publication years analysed. Secondly, data analyses refer to the numbers of cited references from the German-speaking countries, which are also documented in PSYNDEX. These compose about 11 % of all cited references indicating that nearly 90 % of the references cited are of international and/or interdisciplinary publications not stemming from the German-speaking countries. The subsample shows the proportion of journal articles, books, and chapters, and these are very similar to the percentages identified for all references that are cited. Thirdly, analyses refer to document type, scientific genre, and psychological sub-discipline of the most frequently cited references in the psychology publications. The frequency of top-cited references of books and book chapters is almost equal to that of journal articles; two-thirds of the top-cited references are non-empirical publications, only one-third are empirical publications. Top-cited references stem particularly from clinical psychology, experimental psychology, as well as tests, testing and psychometrics. In summary, the results point to the fact that citation analyses, which are limited to journal papers, tend to neglect very high portions of references that are cited in scientific publications.

    After the introduction of the Nuclear Regulatory Authority (NRA) reopened NRA, the participants familiarised themselves with the history of M.I.5 (1980-2008), with the decisions of the NRA issued in 2008, with the law-suit and the judgement of the Supreme Court of the Slovak Republic, with the course of the procedure after the judgement, and with the comments, proposals and suggestions of the procedure participants delivered to the Authority within the specified period. The public hearing of the comments was followed by technical comments of the procedure participants focused on events at one unit that can affect the neighbouring unit, containment concept, seismic threat and accidents with fuel melting, which were fully answered by the competent persons. The hearing ended with a discussion.

  3. From Excessive Journal Self-Cites to Citation Stacking: Analysis of Journal Self-Citation Kinetics in Search for Journals, Which Boost Their Scientometric Indicators.

    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

    Reports of randomized controlled trials (RCTs) should set findings within the context of previous research. The resulting network of citations would also provide an alternative search method for clinicians, researchers, and systematic reviewers seeking to base decisions on all available evidence. We sought to determine the connectedness of citation networks of RCTs by examining direct (referenced trials) and indirect (through references of referenced trials, etc) citation of trials to one another. Meta-analyses were used to create citation networks of RCTs addressing the same clinical questions. The primary measure was the proportion of networks where following citation links between RCTs identifies the complete set of RCTs, forming a single connected citation group. Other measures included the number of disconnected groups (islands) within each network, the number of citations in the network relative to the maximum possible, and the maximum number of links in the path between two connected trials (a measure of indirectness of citations). We included 259 meta-analyses with a total of 2,413 and a median of seven RCTs each. For 46% (118 of 259) of networks, the RCTs formed a single connected citation group-one island. For the other 54% of networks, where at least one RCT group was not cited by others, 39% had two citation islands and 4% (10 of 257) had 10 or more islands. On average, the citation networks had 38% of the possible citations to other trials (if each trial had cited all earlier trials). The number of citation islands and the maximum number of citation links increased with increasing numbers of trials in the network. Available evidence to answer a clinical question may be identified by using network citations created with a small initial corpus of eligible trials. However, the number of islands means that citation networks cannot be relied on for evidence retrieval. Copyright © 2014 Elsevier Inc. All rights reserved.

    2012-01-01

    The large amount of information contained in bibliographic databases has recently boosted the use of citations, and other indicators based on citation numbers, as tools for the quantitative assessment of scientific research. Citations counts are often interpreted as proxies for the scientific influence of papers, journals, scholars, and institutions. However, a rigorous and scientifically grounded methodology for a correct use of citation counts is still missing. In particular, cross-disciplinary comparisons in terms of raw citation counts systematically favors scientific disciplines with higher citation and publication rates. Here we perform an exhaustive study of the citation patterns of millions of papers, and derive a simple transformation of citation counts able to suppress the disproportionate citation counts among scientific domains. We find that the transformation is well described by a power-law function, and that the parameter values of the transformation are typical features of each scientific discipline. Universal properties of citation patterns descend therefore from the fact that citation distributions for papers in a specific field are all part of the same family of univariate distributions.

    The recent publication of a commentary article by Dadkhah et al. (J Cell Commun Signal 11:181-185, 2017) which addressed issues raised by the citation of questionable scientific papers in current databases and the recent retraction of manuscripts dealing with the biological properties of the CCN1 protein by Lin et al. (J Biol Chem 291(53):27433, 2016) prompted us to examine how this situation reflects an evolution of the original citation system, endangering scientific communication. We argue that the increasing number of publication retractions that have been witnessed over several years is a direct consequence of the bias created by the inconsistency of citation metrics.

  9. Gender Differences in Synchronous and Diachronous Self-citations

    2016-07-01

    Citation rates are increasingly used as a currency of science, providing a basis to reward a scientist. Self-citations, an inevitable part of scholarly communication, may contribute to the inflation of citation counts and impose a considerable impact on research evaluation and academic career advancements. Self-citations are classified into two types in this study: synchronous self-citations (self-citations an author gives) and diachronous self-citations (selfcitations an author receives). The main objective of this paper is to provide a comprehensive gendered analysis of synchronous and diachronous self-citations across all scientific disciplines. For this purpose, citation data of 12,725,171 articles published in 2008-2014 are extracted from Web of Science and are further scrutinized for articles of each gender. The findings reveal that men receive citations from their own papers at a higher rate than their women counterparts. They also tend to give more citations to their own publications. Gender gap in citation impact decreases when first-author’s diachronous citations are eliminated in the impact analysis. However, the gap does not vary when all-authors’ diachronous citations are excluded. The results of this research is important for effective gender-related policy-making in the science and technology arena. (Author)

    The data on the top 20 journals in the Science Citation Index(Expanded) for 10 years from 2005 to 2014 indicated the first and second positions for Korean papers were occupied by the Korean journals, which implied the need for globalization of target journals to publish Korean papers. Further study is required for comparative analysis of the factors impacting on the number of papers and citations, which is the criteria for quality evaluation of papers, in other area than the Nuclear Energy and Engineering to which this study was limited. As the media for research process and results, papers play an important role in the evaluation of research projects. While the traditional methods for evaluation of research results have been focused on quantity aspects, the implication of quality aspect is increasingly recognized. Most national labs have begun to shift from quantity to quality in their criteria for overall evaluation of research results. It is therefore desired to maximize the quality level of the research papers for which the trends in citation as quality indicator could be analyzed as well as the quantity aspect. This paper looks at the trends in the number of citation and papers as the indicators of quality and quantify, as drawn from Scopus Data Base. It also suggest top 5 Science Citation Index(Expanded) journals in terms of increase rate in both number of papers and citations. The purpose is to compare them with top 20 Science Citation Index(Expanded) journals in which Korea Atomic Energy Research researchers have published their papers in the past 10 years from 2005 to 2014 were submitted. This paper looked at the trends in the number of papers and citations as an indicator of quality of the research papers in the area of Nuclear Energy and Engineering which is in fact a limitation to the key subject area, not covering the whole nuclear science and technology.

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

  17. Honorary authorship epidemic in scholarly publications? How the current use of citation-based evaluative metrics make (pseudo)honorary authors from honest contributors of every multi-author article.

    Science.gov (United States)

    Kovacs, Jozsef

    2013-08-01

    The current use of citation-based metrics to evaluate the research output of individual researchers is highly discriminatory because they are uniformly applied to authors of single-author articles as well as contributors of multi-author papers. In the latter case, these quantitative measures are counted, as if each contributor were the single author of the full article. In this way, each and every contributor is assigned the full impact-factor score and all the citations that the article has received. This has a multiplication effect on each contributor's citation-based evaluative metrics of multi-author articles, because the more contributors an article has, the more undeserved credit is assigned to each of them. In this paper, I argue that this unfair system could be made fairer by requesting the contributors of multi-author articles to describe the nature of their contribution, and to assign a numerical value to their degree of relative contribution. In this way, we could create a contribution-specific index of each contributor for each citation metric. This would be a strong disincentive against honorary authorship and publication cartels, because it would transform the current win-win strategy of accepting honorary authors in the byline into a zero-sum game for each contributor.

    Purpose To determine if adherence to the Standards for Reporting of Diagnostic Accuracy (STARD) is associated with postpublication citation rates. Materials and Methods A comprehensive search of PubMed, EMBASE, and Cochrane Library databases was performed to identify published articles that have evaluated adherence of diagnostic accuracy studies to the STARD statement. These were included if the number of STARD items reported ("STARD result") could be obtained for each evaluated study. The date of publication, journal impact factor, and citation rate (citations per day) were extracted for the diagnostic accuracy studies. Univariate correlations were performed to identify any association between STARD result, impact factor, and citation rate. Multivariate regression analysis was performed to explore the effect of impact factor on postpublication citation rates. Results The authors were able to obtain the STARD results for 1002 "original" diagnostic accuracy studies from eight different "STARD evaluation" articles. The median impact factor was 3.97 (interquartile range [IQR]: 2.32-6.21), the median STARD result was 15 of 25 items (IQR: 12-18), and the median citation rate was 0.007 citations per day (IQR: 0.0032-0.017). The authors identified a weak positive correlation between STARD result and citation rate (r = 0.096; 95% confidence interval [CI]: 0.034, 0.157), a moderate positive correlation between impact factor and citation rate (r = 0.58; 95% CI: 0.535, 0.617), and a weak positive correlation between impact factor and STARD result (r = 0.13; 95% CI: 0.064, 0.186). Multivariate analysis accounting for journal clustering effects revealed that, when impact factor is partialed out, the positive correlation between citation rate and STARD result does not persist (r = 0.029; 95% CI: -0.033, 0.091). Conclusion There is a positive correlation between completeness of reporting, as evaluated with STARD, and citation rate as well as impact factor. When adjusted for

    Full Text Available INTRODUCTION Data citation should be a necessary corollary of data publication and reuse. Many researchers are reluctant to share their data, yet they are increasingly encouraged to do just that. Reward structures must be in place to encourage data publication, and citation is the appropriate tool for scholarly acknowledgment. Data citation also allows for the identification, retrieval, replication, and verification of data underlying published studies. METHODS This study examines author behavior and sources of instruction in disciplinary and cultural norms for writing style and citation via a content analysis of journal articles, author instructions, style manuals, and data publishers. Instances of data citation are benchmarked against a Data Citation Adequacy Index. RESULTS Roughly half of journals point toward a style manual that addresses data citation, but the majority of journal articles failed to include an adequate citation to data used in secondary analysis studies. DISCUSSION Full citation of data is not currently a normative behavior in scholarly writing. Multiplicity of data types and lack of awareness regarding existing standards contribute to the problem. CONCLUSION Citations for data must be promoted as an essential component of data publication, sharing, and reuse. Despite confounding factors, librarians and information professionals are well-positioned and should persist in advancing data citation as a normative practice across domains. Doing so promotes a value proposition for data sharing and secondary research broadly, thereby accelerating the pace of scientific research.

    In scientific circles, the reference is the information that is necessary to the reader in identifying and finding used sources. The basic rule when listing the sources used is that references must be accurate, complete and should be consistently applied. On the other hand, quoting implies verbatim written or verbal repetition of parts of the text or words written by others that can be checked in original. Authors of every new scientific article need to explain how their study or research fits with previous one in the same or similar fields. A typical article in the health sciences refers to approximately 20-30 other articles published in peer reviewed journals, cite once or hundreds times. Citations typically appear in two formats: a) as in-text citations where the sources of information are briefly identified in the text; or b) in the reference list at the end of the publication (book chapter, manuscript, article, etc.) that provides full bibliographic information for each source.

    Measures of research productivity are increasingly used to determine how research should be evaluated and funding decisions made. In psychiatry, citation patterns within and between countries are not known, and whether these differ by choice of citation metric. In this study, we examined publication characteristics and citation practices in articles published in 50 Web of Science indexed psychiatric and relevant clinical neurosciences journals, between January 2004 and December 2009 comprising 51,072 records that produced 375,962 citations. We compared citation patterns, including self-citations, between countries using standard x(2) tests. We found that most publications came from the USA, with Germany being second and UK third in productivity. USA articles received most citations and the highest citation rate with an average 11.5 citations per article. The UK received the second highest absolute number of citations, but came fourth by citation rate (9.7 citations/article), after the Netherlands (11.4 citations/article) and Canada (9.8 citations/article). Within the USA, Harvard University published most articles and these articles were the most cited, on average 20.0 citations per paper. In Europe, UK institutions published and were cited most often. The Institute of Psychiatry/Kings College London was the leading institution in terms of number of published records and overall citations, while Oxford University had the highest citation rate (18.5 citations/record). There were no differences between the self-citation practices of American and European researchers. Articles that examined some aspect of treatment in psychiatry were the most published. In terms of diagnosis, papers about schizophrenia-spectrum disorders were the most published and the most cited. We found large differences between and within countries in terms of their research productivity in psychiatry and clinical neuroscience. In addition, the ranking of countries and institutions differed widely

    Full Text Available The purpose of this study was to assess the relationship between altmetrics measures of F1000 website and citation Indexes of Google scholar. Applied research and survey methods, citation analysis, and webometrics with descriptive analytical approach are used. The study population comprised 218 biomedical research papers have been indexed in F1000 system in the period 2012-2014. A sample of 100 research articles were purposely selected from F1000 system based on the purpose of the research. Variables associated with altmetrics measures were extracted from F1000 and variables associated with citation measures were from Google scholar. Data analysis was conducted by SPSS software version 16 using descriptive and inferential statistics. The results of this study indicate a significant positive correlation between variables associated with altmetrics and citation measures. They also confirm a strong positive correlation between Altmetrics indicators. However, the measures of the number of the authors and the funding supply of the articles show no significant correlation with altmetrics and citation measures. So an Altmetrics measure presents a new way to measure the impact of writers and publications which is a complementary to traditional assessment indicators. The significant correlation between altmetrics and citation metrics indicate that combination of traditional and altmetrics indicators presents a more complete history of the writer or the article  which provides clear dimensions of scientific assessment of research.

    most for condensed matter physics. This study did not identify any one of these three resources as the answer to all citation tracking needs. Scopus showed strength in providing citing literature for current (2003) oncology articles, while Web of Science produced more citing material for 2003 and 1993 condensed matter physics, and 1993 oncology articles. All three tools returned some unique material. Our data indicate that the question of which tool provides the most complete set of citing literature may depend on the subject and publication year of a given article.

    We performed a citation analysis of the literature about mindfulness aimed at describing the most significant topics and the impact of more relevant papers. We classified 128 systematic reviews about mindfulness-based intervention retrieved in Scopus according to their object, the population included and the type of mindfulness proposed. The citation counting was reported. The cumulative citation numbers per chronological years and article life were analyzed thorough a linear regression model. 1) We observed a general increase in the number of reviews published from 2003 to 2016; 2) two reviews collected the 33% of the overall citations; 3) citation counting for clinical and mixed population collected the 90% of total citations; 4) clinical reviews had higher cumulative citation per publication/year growth. As mindfulness research advances, higher attention should be given to the mechanisms by which mindfulness interventions work so as to provide fruitful insights for future research.

    2016-01-01

    Citations measure the importance of a publication, and may serve as a proxy for its popularity and quality of its contents. Here we study the distributions of citations to publications from individual academic institutions for a single year. The average number of citations have large variations between different institutions across the world, but the probability distributions of citations for individual institutions can be rescaled to a common form by scaling the citations by the average number of citations for that institution. We find this feature seems to be universal for a broad selection of institutions irrespective of the average number of citations per article. A similar analysis for citations to publications in a particular journal in a single year reveals similar results. We find high absolute inequality for both these sets, Gini coefficients being around 0.66 and 0.58 for institutions and journals respectively. We also find that the top 25% of the articles hold about 75% of the total citations for institutions and the top 29% of the articles hold about 71% of the total citations for journals. PMID:26751563

    Full Text Available BACKGROUND: The impact of a scientific article is proportional to the citations it has received. In this study, we set out to identify the most cited works in epileptology in order to evaluate research trends in this field. METHODS: According to the Web of Science database, articles with more than 400 citations qualify as "citation classics". We conducted a literature search on the ISI Web of Science bibliometric database for scientific articles relevant to epilepsy. RESULTS: We retrieved 67 highly cited articles (400 or more citations, which were published in 31 journals: 17 clinical studies, 42 laboratory studies, 5 reviews and 3 classification articles. Clinical studies consisted of epidemiological analyses (n=3, studies on the clinical phenomenology of epilepsy (n=5 – including behavioral and prognostic aspects – and articles focusing on pharmacological (n=6 and non-pharmacological (n=3 treatment. The laboratory studies dealt with genetics (n=6, animal models (n=27, and neurobiology (n=9 – including both neurophysiology and neuropathology studies. The majority (61% of citation classics on epilepsy were published after 1986, possibly reflecting the expansion of research interest in laboratory studies driven by the development of new methodologies, specifically in the fields of genetics and animal models. Consequently, clinical studies were highly cited both before and after the mid 80s, whilst laboratory researches became widely cited after 1990. CONCLUSIONS: Our study indicates that the main drivers of scientific impact in the field of epileptology have increasingly become genetic and neurobiological studies, along with research on animal models of epilepsy. These articles are able to gain the highest numbers of citations in the time span of a few years and suggest potential directions for future research.

    The Centers for Medicare & Medicaid Services (CMS) recently instituted physician reimbursements for advance care planning (ACP) discussions with patients. To measure public support for similar programs. Cross-sectional online and in-person surveys. English-speaking adults recruited at public parks in Philadelphia, Pennsylvania, from July to August 2013 and online through survey sampling international Web-based recruitment platform in July 2015. Participants indicated support for 6 programs designed to increase advance directive (AD) completion or ACP discussion using 5-point Likert scales. Participants also indicated how much money (US$0-US$1000) was appropriate to incentivize such behaviors, compared to smoking cessation or colonoscopy screening. We recruited 883 participants: 503 online and 380 in-person. The status quo of no systematic approach to motivate AD completion was supported by 67.0% of participants (63.9%-70.1%). The most popular programs were paying patients to complete ADs (58.0%; 54.5%-61.2%) and requiring patients to complete ADs or declination forms for health insurance (54.1%; 50.8%-57.4%). Participants more commonly supported paying patients to complete ADs than paying physicians whose patients complete ADs (22.6%; 19.8%-25.4%) or paying physicians who document ACP discussions (19.1%; 16.5%-21.7%; both P < .001). Participants supported smaller payments for AD completion and ACP than for obtaining screening colonoscopies or stopping smoking. Americans view payments for AD completion or ACP more skeptically than for other health behaviors and prefer that such payments go to patients rather than physicians. The current CMS policy of reimbursing physicians for ACP conversations with patients was the least preferred of the programs evaluated.

    In scientific writing, positive credits and negative criticisms can often be seen in the text mentioning the cited papers, providing useful information about whether a study can be reproduced or not. In this study, we focus on citation sentiment analysis, which aims to determine the sentiment polarity that the citation context carries towards the cited paper. A citation sentiment corpus was annotated first on clinical trial papers. The effectiveness of n-gram and sentiment lexicon features, and problem-specified structure features for citation sentiment analysis were then examined using the annotated corpus. The combined features from the word n-grams, the sentiment lexicons and the structure information achieved the highest Micro F-score of 0.860 and Macro-F score of 0.719, indicating that it is feasible to use machine learning methods for citation sentiment analysis in biomedical publications. A comprehensive comparison between citation sentiment analysis of clinical trial papers and other general domains were conducted, which additionally highlights the unique challenges within this domain.

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

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

    Many observatories maintain bibliographies to document their impact and justify their continued funding[1], an effort that requires humans to discover and curate links between the scientific papers and the data that was used as evidence. The "Best Practices for Creating a Telescope Bibliography", endorsed by IAU C5 WG Libraries, recommends full text searching and human examination of each paper.[2] These efforts do not scale well.It is unlikely that articles published in journals from other disciples would be found. This is particularly a problem for solar physics, as solar data has applicability in astrophysics, space weather, and even the earth sciences.As our scientists are not on the editorial boards of the journals from other disciplines, we can't ensure proper attribution to allow these relationships to be discovered via full text searching.To better deal with tracking cross-discipline data usage, a number of groups have come up with guidelines and principles for data citation. In 2012, the National Academy's Board on Research Data and Information released the report "For Attribution-Developing Data Attribution and Citation Practices and Standards" [3] and it was followed last year by the CODATA-ICSTI report "Out of Cite, Out of Mind".[4]Participants from a number of groups synthesized a single set of principles for data citation that could be endorsed by all groups involved in research.[5] Implementing these principles can help to improve the scientific ecosystem by giving proper attribution to all contributors to data, improving transparency and reproducability, and making data more easily reusable to both astronomers and other researchers.We will present the Joint Declaration of Data Citation Principles, discuss the implications of them for astronomical data, and recommend steps towards implementation.References:[1] Accomazzi, et.al, 2012. http://adsabs.harvard.edu/abs/2012SPIE.8448E..0KA[2] Bishop, Grothkopf & Lagerstrom, 2012. http://iau-commission5

    1998-01-01

    In the 60's, the general public in Brazil knew little about nuclear energy. The country was under Military Rule since 1964 and, in the public's ind, the Nuclear Program was closely linked to nuclear weapons, being viewed with distrust and, even, fear. Governmental policies in this field were secret - when the decisions were made to built Angra 1 in 1968 and to sign the Nuclear Cooperation Agreement with Germany in 1975 - the public learned about them as a 'fait accompli'. In the late 70's, people started to hear about the delays in the commissioning of Angra 1 and the problems in the construction of the pile foundations of Angra 2. In 1980, following the TMI accident, the Federal Government issued a set of regulations dealing with emergency planning, the Federal and State Civil Defense being responsible for the preparation of the Off-Site Emergency Plan. FURNAS first public information campaign in 1982 dealt with emergency procedures and was directed to the Angra NPP employees and their families; local residents were visited by Civil Defense officials in 1983. At that time, the Brazilian Nuclear Program began to be criticized by concerned scientists and by the press, primarily due to its lack of transparency and its large scope. Safety issues arising from the TMI accident, lack of decision for the radioactive waste storage and problems with some equipment and components that delayed the commissioning of Angra 1, were pointed out as technical arguments against the construction of Angra 2 and 3. A new Constitution, 1988, required that a nuclear projects must be approved by the National Congress and put forward some new provisions for the environmental licensing of major industrial installations. The completion of Angra 2 was considered of the utmost importance by the Brazilian Nuclear Energy Association - ABEN, which is a technical-scientific body comprising employees from the various organizations that form the Brazilian Nuclear Sector.

    2005-03-01

    This study analyzes the accuracy of anecdotes cited in behavioral primatology publications. Anecdotes (n=1 cases) recounting tool use were sought in the four main primatological journals. Citations of anecdotes in the scientific literature that met three criteria were systematically coded for recognition and accuracy. The results showed that 60% of the time, authors who cited anecdotes did not explicitly acknowledge them as such. To a lesser extent, the citations exaggerated the frequency of anecdotal events or misrepresented their status. For tool use specifically, the actor was misreported more often than the tool or its target. Multiple citations were incorrect more often than single citations. Overall, it seems that citation of anecdotes is problematic and may have far-reaching implications in terms of misleading overgeneralizations. Primatologists should take care in citing singular or rare events. Copyright (c) 2005 Wiley-Liss, Inc.

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

    A paradigm change in scholarly communication is underway. Supporting Open Science, an effort to make scientific research data accessible to all interested parties by openly publishing research and encouraging others to do the same thereby making it easier to communicate scientific knowledge, is a part of the change that has become increasingly important for (digital) libraries. Digital libraries are able to play a significant role in enabling Open Science by facilitating data sharing, discovery and re-use. Because data citation is often mentioned as one incentive for data sharing, enabling data citation is a crucial feature of research data services. In this article we present a case study of data citation services for the High-Energy Physics (HEP) community using digital library technology. Our example shows how the concept of data citation is implemented for the complete research workflow, covering data production, publishing, citation and tracking of data reuse. We also describe challenges faced and distil...

    An overview of the Data Citation Index is provided. Thomson Reuters developed this resource in response to a stated desire among members of the research community for increased attribution of non-traditional scholarly output. Launched in October of 2012 on the Web of science research platform, its aims include linking published research articles to their underlying data sets and tracking the citation of the data, as well as encouraging bibliographic citation of data. Cross-disciplinary search capabilities in the Index enable new possibilities for data discovery and synthesis. Data repositories are evaluated with respect to various selection criteria, with particular attention to their relevance to scientific and scholarly research. Index content reflects current data deposition practices. As data citation standards and practices continue to move toward widespread formalization and adoption, the initiative seeks to address issues of data citation, reuse, and author credit in a developing climate.

    2014-02-01

    The purpose of this study was to conduct a historical review of psycho-oncology and supportive care research in Canada using citation analysis and to review the clinical impact of the research conducted by the most highly cited researchers. The lifetime journal publication records of 109 psycho-oncology and supportive care researchers in Canada were subject to citation analysis using the Scopus database, based on citations since 1996 of articles deemed relevant to psychosocial oncology and supportive care, excluding self-citations. Three primary types of analysis were performed for each individual: the number of citations for each journal publication, a summative citation count of all published articles, and the Scopus h-index. The top 20 psycho-oncology/supportive care researchers for each of five citation categories are presented: the number of citations for all publications; the number of citations for first-authored publications; the most highly cited first-authored publications; the Scopus h-index for all publications; and the Scopus h-index for first-authored publications. The three most highly cited Canadian psycho-oncology researchers are Dr. Kerry Courneya (University of Alberta), Dr. Lesley Degner, (University of Manitoba), and Dr. Harvey Chochinov (University of Manitoba). Citation analysis is useful for examining the research performance of psycho-oncology and supportive care researchers and identifying leaders among them.

    The purpose of this study is to determine and characterize the scientific and nonscientific factors that influence the rate of article citation in the field of plastic surgery. Cross-sectional study. We reviewed all entries in Annals of Plastic Surgery and Journal of Plastic, Reconstructive, and Aesthetic Surgery from January 1, 2007 to December 31, 2007; and Plastic and Reconstructive Surgery from January 1, 2007 to December 31, 2008. All scientific articles were analyzed and several article characteristics were extracted. The number of citations at 5 years was collected as the outcome variable. A multivariable analysis was performed to determine which variables were associated with higher citations rates. A total of 2456 articles were identified of which only 908 fulfilled the inclusion criteria. Most studies were publications in the fields of reconstructive (26.3%) or pediatric/craniofacial (17.6%) surgery. The median number of citations 5 years from publication was 8. In the multivariable analysis, factors associated with higher citations rates were subspecialty field (p = 0.0003), disclosed conflict of interest (p = 0.04), number of authors (p = 0.04), and journal (p = 0.02). We have found that higher level of evidence (or other study methodology factors) is not associated with higher citation rates. Instead, conflict of interest, subspecialty topic, journal, and number of authors are strong predictors of high citation rates in plastic surgery.

    Quantitative measures of research productivity depend on the citation frequency of a publication. Citation-based metrics, such as the h-index (total number of publications h that have at least h citations), can be susceptible to self-citation, resulting in an inflated measure of research productivity. The purpose of the present study was to estimate the effect of self-citation on the h-index among academic oral and maxillofacial surgeons (OMSs). The present study was a cross-sectional study of full-time academic OMSs in the United States. The predictor variable was the frequency of self-citation. The primary outcome of interest was the h-index. Other study variables included demographic factors and citation metrics. Descriptive, bivariate, and regression statistics were computed. The study sample consisted of 325 full-time academic OMSs. Most surgeons were men (88.3%); approximately 40% had medical degrees. The study subjects had an average of 23.5 ± 37.1 publications. The mean number of self-citations was 15 + 56. The sample's mean h-index was 6.6 ± 7.6 and was associated with self-citation (r = 0.71, P citations. After adjusting for PhD degree, total number of publications, and academic rank, an increasing self-citation rate influenced the h-index (r = 0.006, P citations were more likely to have their h-index influenced by self-citation. Self-citation among full-time academic OMSs does not substantially affect the h-index. Surgeons in the top quartile of self-citation rates are more likely to influence their h-index.

    A recent review of frameworks used in dissemination and implementation (D&I) science described 61 judged to be related either to dissemination, implementation, or both. The current use of these frameworks and their contributions to D&I science more broadly has yet to be reviewed. For these reasons, our objective was to determine the role of these frameworks in the development of D&I science. We used the Web of Science™ Core Collection and Google Scholar™ to conduct a citation network analysis for the key frameworks described in a recent systematic review of D&I frameworks (Am J Prev Med 43(3):337-350, 2012). From January to August 2016, we collected framework data including title, reference, publication year, and citations per year and conducted descriptive and main path network analyses to identify those most important in holding the current citation network for D&I frameworks together. The source article contained 119 cited references, with 50 published articles and 11 documents identified as a primary framework reference. The average citations per year for the 61 frameworks reviewed ranged from 0.7 to 103.3 among articles published from 1985 to 2012. Citation rates from all frameworks are reported with citation network analyses for the framework review article and ten highly cited framework seed articles. The main path for the D&I framework citation network is presented. We examined citation rates and the main paths through the citation network to delineate the current landscape of D&I framework research, and opportunities for advancing framework development and use. Dissemination and implementation researchers and practitioners may consider frequency of framework citation and our network findings when planning implementation efforts to build upon this foundation and promote systematic advances in D&I science.

  17. Can scientific journals be classified based on their citation profiles?

    Full Text Available Classification of scientific publications is of great importance in biomedical research evaluation. However, accurate classification of research publications is challenging and normally is performed in a rather subjective way. In the present paper, we propose to classify biomedical publications into superfamilies, by analysing their citation profiles, i.e. the location of citations in the structure of citing articles. Such a classification may help authors to find the appropriate biomedical journal for publication, may make journal comparisons more rational, and may even help planners to better track the consequences of their policies on biomedical research.

    2018-01-01

    Bibliometrics involves the statistical analysis of the publications in a specific discipline or subject area. A bibliometric analysis of the occupational therapy refereed literature is needed. A bibliometric analysis was completed of the occupational therapy literature from 1991-2014, indexed in the Science Citation Index-Expanded or the Social Sciences Citation Index. Publications were searched by title, abstract, keywords, and KeyWords Plus. Total number of article citations, citations per journal, and contributions per country, individual authors, and institution were calculated. 5,315 occupational therapy articles were published in 821 journals. It appears that there is a citation window of an approximate 10-year period between the time of publication and the peak number of citations an article receives. The top three most highly cited articles were published in Developmental Medicine and Child Neurology, JAMA, and Lancet. AJOT, BJOT and AOTJ published the largest number of occupational therapy articles with the United States, Australia, and Canada producing the highest number of publications. McMaster University, the University of Queensland, and the University of Toronto were the institutions that published the largest number of occupational therapy journal articles. The occupational therapy literature is growing and the frequency of article citation is increasing.

  20. Data Citation Policies of Data Providers within the scope of Longitudinal Studies in Life Course Research

    In this article, a small-scale case study analyzing the nature of data citation policies within the scope of longitudinal studies in life course research is presented. The sample consists of eight data providers from Europe, North-America and Australia and was evaluated with regard to eight criteria which potentially affect data citation behavior of researchers in the field, for example the wording of data citation obligations or sanctions for not citing research data in accordance to given requirements. The study demonstrates that research data providers follow a wide range of approaches to data citation, especially in terms of data citation location within a publication as well as disposal obligations for data-related publications. However, this diversity might lead to inconsistency in data citation behaviour and also to a general lack of comparability of data citation quantity and quality as relevant factors in research evaluation.

    Citation screening, an integral process within systematic reviews that identifies citations relevant to the underlying research question, is a time-consuming and resource-intensive task. During the screening task, analysts manually assign a label to each citation, to designate whether a citation is eligible for inclusion in the review. Recently, several studies have explored the use of active learning in text classification to reduce the human workload involved in the screening task. However, existing approaches require a significant amount of manually labelled citations for the text classification to achieve a robust performance. In this paper, we propose a semi-supervised method that identifies relevant citations as early as possible in the screening process by exploiting the pairwise similarities between labelled and unlabelled citations to improve the classification performance without additional manual labelling effort. Our approach is based on the hypothesis that similar citations share the same label (e.g., if one citation should be included, then other similar citations should be included also). To calculate the similarity between labelled and unlabelled citations we investigate two different feature spaces, namely a bag-of-words and a spectral embedding based on the bag-of-words. The semi-supervised method propagates the classification codes of manually labelled citations to neighbouring unlabelled citations in the feature space. The automatically labelled citations are combined with the manually labelled citations to form an augmented training set. For evaluation purposes, we apply our method to reviews from clinical and public health. The results show that our semi-supervised method with label propagation achieves statistically significant improvements over two state-of-the-art active learning approaches across both clinical and public health reviews.

    The collection, communication, and sharing of data relating to the 2010 Deepwater Horizon oil spill proved to be a case study in the lack of data transparency and poor collaboration on a variety of levels. British Petroleum and the government worked together to keep the public out of the spill area while collecting over 31,000 water and sediment samples from the Gulf of Mexico after the initial explosion in April, 2010. Although thousands of images were immediately collected by the National Oceanic and Atmospheric Administration and the US Geological Survey, some of those raw data sets still remain inaccessible, are in difficult to use formats, or have been modified for public release. The lack of sharing of information by federal agencies and BP was particularly frustrating given the use of publicly funded resources. Discrepancies between information posted on federal and state websites and conditions in the field were apparent and a key factor in the poor relations between authorities and local residents. The conditions under which data is collected, the affiliation of the authors, and the intended use, vastly impacts how well we trust those data. The solution, we believe, is for local communities to produce their own high-quality data through collaboration with organizations such as The Public Laboratory for Open Technology and Science. The Public Laboratory community worked with Gulf Coast residents in the field to document the effects of oil on shorelines with do-it-yourself aerial photography. For less than 100 in parts, we used helium balloons and kites to send cameras to over a thousand feet, and stitched the resulting images into high-resolution maps using our free, open-source software. Over a hundred volunteers hit the beaches to take tens of thousands of photos, depicting slicks, oiled wetlands, and the birds, fish, and plants threatened by the disaster. Our efforts resulted in the largest repository of publicly archived oil spill data to date and it is

    Full Text Available Whilst their 'death' has often been certified, books remain highly important to most professions and academic disciplines. Analyses of citations received by epidemiologic texts may complement other views on epidemiology. The objective was to assess the number of citations received by some books of epidemiology and public health, as a first step towards studying the influence of epidemiological thought and thinking in academia. For this purpose, Institute for Scientific Information/ Thomson Scientific - Web of Science/ Web of Knowledgedatabase was consulted, in May 2006. The book by Rothman & Greenland appeared to have received the highest number of citations overall (over 8,000 and per year. The books by Kleinbaum et al, and by Breslow & Day received around 5,000 citations. In terms of citations per year the book by Sackett et al ranks 3rd, and the one by Rose, 4th of those included in this preliminary study. Other books which were influential in the classrooms collected comparatively less citations. Results offer a rich picture of the academic influences and trends of epidemiologic methods and reasoning on public health, clinical medicine and the other health, life and social sciences. They may contribute to assess epidemiologists' efforts to demarcate epidemiology and to assert epistemic authority, and to analyze some historical influences of economic, social and political forces on epidemiological research.

  5. The scientific impact of nations: journal placement and citation performance.

    Directory of Open Access Journals (Sweden)

    Matthew J Smith

    Full Text Available International collaboration is becoming increasingly important for the advancement of science. To gain a more precise understanding of how factors such as international collaboration influence publication success, we divide publication success into two categories: journal placement and citation performance. Analyzing all papers published between 1996 and 2012 in eight disciplines, we find that those with more countries in their affiliations performed better in both categories. Furthermore, specific countries vary in their effects both individually and in combination. Finally, we look at the relationship between national output (in papers published and input (in citations received over the 17 years, expanding upon prior depictions by also plotting an expected proportion of citations based on Journal Placement. Discrepancies between this expectation and the realized proportion of citations illuminate trends in performance, such as the decline of the Global North in response to rapidly developing countries, especially China. Yet, most countries' show little to no discrepancy, meaning that, in most cases, citation proportion can be predicted by Journal Placement alone. This reveals an extreme asymmetry between the opinions of a few reviewers and the degree to which paper acceptance and citation rates influence career advancement.

    Little is known about the extent and nature of publication bias in economic evaluations. Our objective was to determine whether economic evaluations are subject to publication bias by considering whether economic data are as likely to be reported, and reported as promptly, as effectiveness data. Trials that intended to conduct an economic analysis and ended before 2008 were identified in the International Standard Randomised Controlled Trial Number (ISRCTN) register; a random sample of 100 trials was retrieved. Fifty comparator trials were randomly drawn from those not identified as intending to conduct an economic study. The trial start and end dates, estimated sample size and funder type were extracted. For trials planning economic evaluations, effectiveness and economic publications were sought; publication dates and journal impact factors were extracted. Effectiveness abstracts were assessed for whether they reached a firm conclusion that one intervention was most effective. Primary investigators were contacted about reasons for non-publication of results, or reasons for differential publication strategies for effectiveness and economic results. Trials planning an economic study were more likely to be funded by government (p = 0.01) and larger (p = 0.003) than other trials. The trials planning an economic evaluation had a mean of 6.5 (range 2.7-13.2) years since the trial end in which to publish their results. Effectiveness results were reported by 70 %, while only 43 % published economic evaluations (p economic results included the intervention being ineffective, and staffing issues. Funding source, time since trial end and length of study were not associated with a higher probability of publishing the economic evaluation. However, studies that were small or of unknown size were significantly less likely to publish economic evaluations than large studies (p journal impact factor was 1.6 points higher for effectiveness publications than for the

The paper analyzed the life cycle of scientific publications and show that the way to promote scientific articles in the world community inherent properties of Markov processes. Application of Markov chains allows top ground the need for active participation of the authors in the distribution of its publications in different scientometric databases, repositories of scientific and social networks. Markov model to describe decomposition of scientists made certain discrete states and proposed a schematic diagram of transitions between them. The model's 5A fully reflect the properties of the system. Communication influences the probability of changing system states with consistent movement along the trajectory from a lack of information about the publication to familiarize with it because of the positive attitude to state its citation. This is a must as well as a negative attitude to the publications. Proved that improve performance citation of scientific publications in the case of using Google Scholar, ORCID, Mendeley, Academia, ResearchGate, and others. The active participation of authors in their publications available in these systems leads to an increase in the proportion of articles that are available to colleagues in the global scientific community that is becoming one of the factors of increase in citations.

    Research productivity plays a significant role in academic promotions. Currently, various bibliometric measures utilizing citation counts are used to judge an author's work. With increasing numbers of journals, numbers of open access publications, ease of online submission, and expedited indexing of accepted manuscripts, it is plausible that an author could influence his/her own bibliometric measures through self-citation. The purpose of this study was to determine the impact of self-citation in academic plastic surgery. A cohort of full-time academic plastic surgeons was identified from 9 U.S. plastic surgery training programs. For all included faculty, academic rank was retrieved from department/division websites, and bibliometric measures were assessed using a subscription bibliographic citation database (Scopus, Reed Elsevier, London, UK). Bibliometric measures included the Hirsch index (h-index, the number of publications h which are cited ≥ h times), total number of publications, and total number of citations. The h-index and total number of citations were collected with and without self-citations. Percent changes in the h-index and total citations were calculated after removal of self-citations and compared across academic ranks and levels of research productivity (total publications, h-index, and total citations). The study cohort consisted of 169 full-time academic plastic surgeons. The h-index and total citations experienced decreases of 2.8 ± 5.0% (P citation. More than half of the cohort (n = 113, 67%) did not experience a change in the h-index after removal of self-citations. These decreases did not vary across academic rank. Surgeons who self-cited at rates greater than 5% were 9.8 times more likely (95% confidence interval, 4.5-21.9; P citation (after adjusting for academic rank). There were weak correlations between percent decreases in the h-index and total citations and various biblimoteric measures (total publications, h-index, total citations

    Small-scale quality improvement projects are expected to make a significant contribution towards improving the quality of healthcare. Enabling doctors-in-training to design and lead quality improvement projects is important preparation for independent practice. Participation is mandatory in speciality training curricula. However, provision of training and ongoing support in quality improvement methods and practice is variable. We aimed to design and deliver a quality improvement training package to core medical and general practice specialty trainees and evaluate impact in terms of project participation, completion and publication in a healthcare journal. A quality improvement training package was developed and delivered to core medical trainees and general practice specialty trainees in the west of Scotland encompassing a 1-day workshop and mentoring during completion of a quality improvement project over 3 months. A mixed methods evaluation was undertaken and data collected via questionnaire surveys, knowledge assessment, and formative assessment of project proposals, completed quality improvement projects and publication success. Twenty-three participants attended the training day with 20 submitting a project proposal (87%). Ten completed quality improvement projects (43%), eight were judged as satisfactory (35%), and four were submitted and accepted for journal publication (17%). Knowledge and confidence in aspects of quality improvement improved during the pilot, while early feedback on project proposals was valued (85.7%). This small study reports modest success in training core medical trainees and general practice specialty trainees in quality improvement. Many gained knowledge of, confidence in and experience of quality improvement, while journal publication was shown to be possible. The development of educational resources to aid quality improvement project completion and mentoring support is necessary if expectations for quality improvement are to be

    This study extended research on key citation metrics of winners of two career scholar awards in sports biomechanics. Google Scholar (GS) was searched using Harzing's Publish or Perish software for the 13 most recent winners of the ISBS Geoffrey Dyson Award and the ASB Jim Hay Memorial Award. Returned records were corrected for author, and publications excluded for all but peer-reviewed journal articles, proceedings articles, chapters and books in English. These recent award winners had published about 150 publications that had been cited typically 4,082 and 6,648 times over a 26- and 28-year period before receiving these career awards for sports biomechanics research. Estimated median citations at time of their awards were 2,927 and 4,907 for the Dyson and Hay awards, respectively. Award winners had mean Hirsh indexes of 32-45 and mean h i of 19-28. Their mean g indexes (59-84) and their numerous citation classics (C > 100) indicated that they had many influential publications. The citation metrics of these scholars were outstanding and consistent with recent studies of top scholars in biomechanics and kinesiology/exercise science. Careful searching, cleaning and interpretation of several scholar-level citation metrics may provide useful confirmatory evidence for evaluations of awards committees.

    1998-01-01

    Full text: As usual in P.R., there was a complicated, politically sensitive situation we had to face at the beginning and it wasn't easy to create the right P.R. programme with the right targets: CEZ needed a new storage facility for the nuclear spent fuel from its two NPPs - Dukovany and Temelin. Firstly, CEZ preferred to build an on-site facility for the Dukovany NPP to last until the year 2004; secondly, a facility for the Temelin NPP several years later. But the Czech Government decided to limit Dukovany's storage capacity during a public discussion in 1992. Therefore, at the end of 1993, CEZ started the site selection process for a central storage facility targeted at ten regions in the country. In P.R. we decided on two main goals: 1. To gain public acceptance of a central storage facility at least at one site, and hopefully at more. 2. To change public opinion (especially around the Dukovany NPP) in order to create the proper atmosphere for changing the government's decision to limit storage capacity. We wanted to prove that we could choose the fight technical and economical solution without political limits. This obviously presented a challenge as it would be problematic for CEZ to be very visible in the campaign: We wanted people to know that the government had made a bad decision, but we also had to make it clear that our objections were based not on questions of momentary corporate advantage but instead on solid technical grounds. Most would only see self interest. We wanted to show them the facts. Of course, some times it wasn't easy to hit both targets at the same time. There was a lot of hard work in the middle. We gained new experience and we learned a lot trying to get public confidence in nuclear safety, in our company's reliability and in some local profits for a storage site: Firstly none of those regions was excited by the idea o a storage facility in its backyard. Most of them were very strongly and actively against it and did not want to

  19. Authorship and citation manipulation in academic research

    Science.gov (United States)

    2017-01-01

    Some scholars add authors to their research papers or grant proposals even when those individuals contribute nothing to the research effort. Some journal editors coerce authors to add citations that are not pertinent to their work and some authors pad their reference lists with superfluous citations. How prevalent are these types of manipulation, why do scholars stoop to such practices, and who among us is most susceptible to such ethical lapses? This study builds a framework around how intense competition for limited journal space and research funding can encourage manipulation and then uses that framework to develop hypotheses about who manipulates and why they do so. We test those hypotheses using data from over 12,000 responses to a series of surveys sent to more than 110,000 scholars from eighteen different disciplines spread across science, engineering, social science, business, and health care. We find widespread misattribution in publications and in research proposals with significant variation by academic rank, discipline, sex, publication history, co-authors, etc. Even though the majority of scholars disapprove of such tactics, many feel pressured to make such additions while others suggest that it is just the way the game is played. The findings suggest that certain changes in the review process might help to stem this ethical decline, but progress could be slow. PMID:29211744

  20. Outsourcing and benchmarking in a rural public hospital: does economic theory provide the complete answer?

    Young, S H

    The ideology and pronouncements of the Australian Government in introducing 'competitive neutrality' to the public sector has improved efficiency and resource usage. In the health sector, the Human Services Department directed that non-clinical and clinical areas be market tested through benchmarking services against the private sector, with the possibility of outsourcing. These services included car parking, computing, laundry, engineering, cleaning, catering, medical imaging (radiology), pathology, pharmacy, allied health and general practice. Managers, when they choose between outsourcing, and internal servicing and production, would thus ideally base their decision on economic principles. Williamson's transaction cost theory studies the governance mechanisms that can be used to achieve economic efficiency and proposes that the optimal organisation structure is that which minimises transaction costs or the costs of exchange. Williamson proposes that four variables will affect such costs, namely: (i) frequency of exchange; (ii) asset specificity; (iii) environmental uncertainty; and (iv) threat of opportunism. This paper provides evidence from a rural public hospital and examines whether Williamson's transaction cost theory is applicable. Case study research operates within the interpretivism paradigm and is used in this research to uncover why the outsourcing decision was made. Such research aims to study real-life experiences by examining the way people think and act and, in contrast to positivism, allows the interviewer to participate to better understand the details and features of the experiences. In the present research, individual interviews were conducted with managers of the hospital and owners and staff of the vendor organisations using semi- and unstructured questions to ascertain the extent of, and processes used in, outsourcing specific functional areas, and areas that were not outsourced.

    The h-index is a commonly utilized metric for academic productivity. Previous studies have proposed that self-citation may limit the utility of the h-index. The purpose of this study is to evaluate the impact of self-citation on the h-index among orthopedic investigators. The study cohort consisted of program directors, chairpersons, and faculty at orthopedic surgery residency programs in the United States. The Scopus database was used to determine the h-index and number of citations ± self-citations. The total number of publications was correlated with the change in the h-index via self-citation. A total of 463 researchers were included (198 National Institutes of Health-funded faculty, 147 chairpersons, 118 program directors). Of these researchers, 83.8% cited previous work at least once (mean, 123.9 ± 277.6). Self-citations accounted for 5.8% of all citations. Including these citations increased the author h-index from 18.5 ± 14.9 to 19.2 ± 15.6 (P < .001). A minority of researchers (36.3%, P < .001) had increased their h-index via self-citation (range, 0-11). The proportional increase in the h-index via self-citation was positively related to the number of publications (P < .001). While the practice of self-citation is prevalent in orthopedics, its impact on the h-index is minimal for most researchers. With more publications, researchers can increase their h-index to a greater degree via self-citation.

    (EPO and an anabolic drug respectively) on information provided by customs officers. Both athletes were banned from competition for two years. Legal basis: Of importance to all the physicians looking after athletes is to know the actual legal basis: The international law basis of the Swiss fight against doping are the Council of Europe Convention against Doping of 16 November 1989 and the International Convention against Doping in Sport of the General Conference of the United Nations Educational, Scientific and Cultural Organization (UNESCO) of 19 October 2005. The basis in public law of the Swiss fight against doping is the Federal Act on the Promotion of Gymnastics and Sport of 17 March 1972. Article 11e, paragraph 1 states that "national sport organisations, the relevant umbrella bodies and bodies responsible for sporting events that are supported in the framework of this act […] are required to ensure that the necessary doping controls are carried out in their area of responsibility". Article 11 f, paragraph 1 of the Federal Act also states that "whoever produces, introduces, transfers, sells, prescribes or provides substances for doping purposes or who uses methods for doping purposes for third persons will be liable to a prison sentence or to a fine of up to 100'000 francs". The civil law basis of the Swiss fight against doping consists of the norms established by various actors in the sporting world. These actors are in most cases clubs, associations and foundations in accordance with the stipulations of the Swiss civil code. The Swiss Olympic Association's revised Doping Statute was approved by the Sports Parliament on 15 November 2008. The statute implements the code of the World Anti-Doping Agency (WADA) in Switzerland. In the introduction it defines the anti-doping agencies in our country: Antidoping Switzerland and the Disciplinary Chamber for Doping Offences of the Swiss Olympic Association. The revised Statute entered into force on 1 January 2009

    Citation between papers can be treated as a causal relationship. In addition, some citation networks have a number of similarities to the causal networks in network cosmology, e.g., the similar in-and out-degree distributions. Hence, it is possible to model the citation network using network cosmology. The casual network models built on homogenous spacetimes have some restrictions when describing some phenomena in citation networks, e.g., the hot papers receive more citations than other simultaneously published papers. We propose an inhomogenous causal network model to model the citation network, the connection mechanism of which well expresses some features of citation. The node growth trend and degree distributions of the generated networks also fit those of some citation networks well.

Attribution to the original contributor upon reuse of published data is important both as a reward for data creators and to document the provenance of research findings. Previous studies have found that papers with publicly available datasets receive a higher number of citations than similar studies without available data. However, few previous analyses have had the statistical power to control for the many variables known to predict citation rate, which has led to uncertain estimates of the “citation benefit”. Furthermore, little is known about patterns in data reuse over time and across datasets. Method and Results. Here, we look at citation rates while controlling for many known citation predictors and investigate the variability of data reuse. In a multivariate regression on 10,555 studies that created gene expression microarray data, we found that studies that made data available in a public repository received 9% (95% confidence interval: 5% to 13% more citations than similar studies for which the data was not made available. Date of publication, journal impact factor, open access status, number of authors, first and last author publication history, corresponding author country, institution citation history, and study topic were included as covariates. The citation benefit varied with date of dataset deposition: a citation benefit was most clear for papers published in 2004 and 2005, at about 30%. Authors published most papers using their own datasets within two years of their first publication on the dataset, whereas data reuse papers published by third-party investigators continued to accumulate for at least six years.

    Citations received by papers published within a journal serve to increase its bibliometric impact. The objective of this paper was to assess the influence of publication language, article type, number of authors, and year of publication on the citations received by papers published in Gaceta Sanitaria, a Spanish-language journal of public health. The information sources were the journal website and the Web of Knowledge, of the Institute of Scientific Information. The period analyzed was from 2007 to 2010. We included original articles, brief original articles, and reviews published within that period. We extracted manually information regarding the variables analyzed and we also differentiated among total citations and self-citations. We constructed logistic regression models to analyze the probability of a Gaceta Sanitaria paper to be cited or not, taking into account the aforementioned independent variables. We also analyzed the probability of receiving citations from non-Spanish authors. Two hundred forty papers fulfilled the inclusion criteria. The included papers received a total of 287 citations, which became 202 when excluding self-citations. The only variable influencing the probability of being cited was the publication year. After excluding never cited papers, time since publication and review papers had the highest probabilities of being cited. Papers in English and review articles had a higher probability of citation from non-Spanish authors. Publication language has no influence on the citations received by a national, non-English journal. Reviews in English have the highest probability of citation from abroad. Editors should decide how to manage this information when deciding policies to raise the bibliometric impact factor of their journals. Copyright © 2012 Elsevier Inc. All rights reserved.

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

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

    Citation bias concerns the selective citation of scientific articles based on their results. We brought together all available evidence on citation bias across scientific disciplines and quantified its impact. An extensive search strategy was applied to the Web of Science Core Collection and Medline, yielding 52 studies in total. We classified these studies on scientific discipline, selection method, and other variables. We also performed random-effects meta-analyses to pool the effect of positive vs. negative results on subsequent citations. Finally, we checked for other determinants of citation as reported in the citation bias literature. Evidence for the occurrence of citation bias was most prominent in the biomedical sciences and least in the natural sciences. Articles with statistically significant results were cited 1.6 (95% confidence interval [CI] 1.3-1.8) times more often than articles with nonsignificant results. Articles in which the authors explicitly conclude to have found support for their hypothesis were cited 2.7 (CI 2.0-3.7) times as often. Article results and journal impact factor were associated with citation more often than any other reported determinant. Similar to what we already know on publication bias, also citation bias can lead to an overrepresentation of positive results and unfounded beliefs. Copyright © 2017 Elsevier Inc.

  2. Development of a Data Citations Database for an Interdisciplinary Data Center

    The scientific community has long depended on consistent citation of the scientific literature to enable traceability, support replication, and facilitate analysis and debate about scientific hypotheses, theories, assumptions, and conclusions. However, only in the past few years has the community focused on consistent citation of scientific data, e.g., through the application of Digital Object Identifiers (DOIs) to data, the development of peer-reviewed data publications, community principles and guidelines, and other mechanisms. This means that, moving ahead, it should be easier to identify and track data citations and conduct systematic bibliometric studies. However, this still leaves the problem that many legacy datasets and past citations lack DOIs, making it difficult to develop a historical baseline or assess trends. With this in mind, the NASA Socioeconomic Data and Applications Center (SEDAC) has developed a searchable citations database, containing more than 3,400 citations of SEDAC data and information products over the past 20 years. These citations were collected through various indices and search tools and in some cases through direct contacts with authors. The citations come from a range of natural, social, health, and engineering science journals, books, reports, and other media. The database can be used to find and extract citations filtered by a range of criteria, enabling quantitative analysis of trends, intercomparisons between data collections, and categorization of citations by type. We present a preliminary analysis of citations for selected SEDAC data collections, in order to establish a baseline and assess options for ongoing metrics to track the impact of SEDAC data on interdisciplinary science. We also present an analysis of the uptake of DOIs within data citations reported in published studies that used SEDAC data.

The scientific, legal, and patent citation systems in America are examined at the micro, meso, and macro levels in order to understand how they function as commodified theories of truth in contemporary knowledge representation. This approach also offers a meta-theoretical overview of existing citation research efforts in science, law, and technology that may be of interdisciplinary interest.

    This paper has two aims: (i) to introduce a novel method for measuring which part of overall citation inequality can be attributed to differences in citation practices across scientific fields, and (ii) to implement an empirical strategy for making meaningful comparisons between the number of citations received by articles in 22 broad fields. The number of citations received by any article is seen as a function of the article's scientific influence, and the field to which it belongs. A key assumption is that articles in the same quantile of any field citation distribution have the same degree of citation impact in their respective field. Using a dataset of 4.4 million articles published in 1998-2003 with a five-year citation window, we estimate that differences in citation practices between the 22 fields account for 14% of overall citation inequality. Our empirical strategy is based on the strong similarities found in the behavior of citation distributions. We obtain three main results. Firstly, we estimate a set of average-based indicators, called exchange rates, to express the citations received by any article in a large interval in terms of the citations received in a reference situation. Secondly, using our exchange rates as normalization factors of the raw citation data reduces the effect of differences in citation practices to, approximately, 2% of overall citation inequality in the normalized citation distributions. Thirdly, we provide an empirical explanation of why the usual normalization procedure based on the fields' mean citation rates is found to be equally successful.

    Full Text Available Data citations have become widely accepted. Technical infrastructures as well as principles and recommendations for data citation are in place but best practices or guidelines for their implementation are not yet available. On the other hand, the scientific climate community requests early citations on evolving data for credit, e.g. for CMIP6 (Coupled Model Intercomparison Project Phase 6. The data citation concept for CMIP6 is presented. The main challenges lie in limited resources, a strict project timeline and the dependency on changes of the data dissemination infrastructure ESGF (Earth System Grid Federation to meet the data citation requirements. Therefore a pragmatic, flexible and extendible approach for the CMIP6 data citation service was developed, consisting of a citation for the full evolving data superset and a data cart approach for citing the concrete used data subset. This two citation approach can be implemented according to the RDA recommendations for evolving data. Because of resource constraints and missing project policies, the implementation of the second part of the citation concept is postponed to CMIP7.

    As research in Earth Science becomes more data intensive, a critical requirement of data archives is that data needs to be easily discovered, accessed, and used. One approach to improving data discovery and access is through data citations coupled with Digital Object Identifiers (DOI). Beginning in 1998, the Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) has issued data product citations that have been accepted and used in AGU and other peer-reviewed journals. Citation elements established by the ORNL DAAC are similar to those used for journal articles (authors, titles, information to locate, and version), and beginning in 2007 included a DOI that is persistent, actionable, specific, and complete. The citation approach used at the DAAC also allows for referring to specific subsets of the data, by including within the citation the temporal and spatial portions of the data actually used. Citations allow others to find data and reproduce the results of the research article, and also use those data to test new hypotheses, design new sample collections, or construct or evaluate models. In addition to enhancing discovery and access of the data used in a research article, the citation gives credit to data generators, data centers and their funders, and, through citation indices, determine the scientific impact of a data set. The ORNL DAAC has developed a database that links research articles and their use of ORNL DAAC data products. The database allows determination of who, in which journal, and how the data have been used, in a manner analogous to author citation indices. The ORNL DAAC has been an initial contributor to the Thomson Reuters Data Citation Index. In addition, research data products deposited at the ORNL DAAC are linked using DOIs to relevant articles in Elsevier journals available on ScienceDirect. The ultimate goal of this implementation is that citations to data products become a routine part of the scientific process.

  7. Software and the Scientist: Coding and Citation Practices in Geodynamics

    Hwang, Lorraine; Fish, Allison; Soito, Laura; Smith, MacKenzie; Kellogg, Louise H.

    In geodynamics as in other scientific areas, computation has become a core component of research, complementing field observation, laboratory analysis, experiment, and theory. Computational tools for data analysis, mapping, visualization, modeling, and simulation are essential for all aspects of the scientific workflow. Specialized scientific software is often developed by geodynamicists for their own use, and this effort represents a distinctive intellectual contribution. Drawing on a geodynamics community that focuses on developing and disseminating scientific software, we assess the current practices of software development and attribution, as well as attitudes about the need and best practices for software citation. We analyzed publications by participants in the Computational Infrastructure for Geodynamics and conducted mixed method surveys of the solid earth geophysics community. From this we learned that coding skills are typically learned informally. Participants considered good code as trusted, reusable, readable, and not overly complex and considered a good coder as one that participates in the community in an open and reasonable manor contributing to both long- and short-term community projects. Participants strongly supported citing software reflected by the high rate a software package was named in the literature and the high rate of citations in the references. However, lacking are clear instructions from developers on how to cite and education of users on what to cite. In addition, citations did not always lead to discoverability of the resource. A unique identifier to the software package itself, community education, and citation tools would contribute to better attribution practices.

  8. Data Citation in Solar Physics: 2015 Update & Recommendations

    Hourclé, Joseph

    2015-04-01

    Last year's Joint Declaration of Data Citation Principles has triggered much discussion about the best ways to handle citation of data across research disciplines. Many communities have gotten together to design solutions to the issues of giving proper credit and attribution, although many fields, including solar physics, have yet to implement them. Issues still exist regarding data citation as a record for scientific reproducability.Solar physics data is particularly difficult to cite due to the nature of our collection methods and the method in which our data are used. Other than sounding rocket or balloon flights, our data collection from a given instrument spans years or decades but observing modes, cadence and field of view may vary daily. Researchers may only analyze a short timespan of the data, only given observing modes, at a slower cadence, and/or only a portion of each image; this reduction should be described to ensure that the analysis is reproducible.Many archives keep only the current, best calibrated data, making updates in place. It can be difficult to determine if the data used in a publication is the same as the currently available data.We discuss the current progress by the Research Data Alliance's Dynamic Data Citation Working Group, and tools and services that would be useful to identify when data may have been changed by an archive. As it may be some time before standards can be developed, we include a checklist for authors to improve reproducibility of their published articles.

    The Korean journal published in English, Nuclear Engineering and Technology (here under NET) has been enlisted in the global citation database SCI E(Science Citation Index Expanded) of Thomson Reuters (past ISI), beginning with NET vol.39 No.1 (Feb. 2007). As of July 2009, the citation index of NET as reported by JCR (Journal Citation Report) based on the cumulative data from ISI (Institute for Scientific Information) reached to 0.991. This index ranks on 12{sup th} among the 33 journals in the area of nuclear science and technology in the science and technology covered by JCR, meaning fairly high impact factor. The following year 2010, however, witnessed the JCR figure dropping down to 0.465. The reason behind such drastic fall would be the decreased citation and in a lesser extent self-citation in 2010, in comparison with 2009, despite the increased number of paper publication. This study attempts to give an analysis as of the end of 2011 on the NET citation frequency in SCI Source Journal and the citation frequency by KAERI authors, together with the nationalities of NET authors and SCI journals that refer to NET most. Based on the analysis, the paper suggests some ways to promoting the position of NET as a journal in the international nuclear sector

    Citation classics have traditionally been defined in the smaller medical specialties as any article published in a peer-reviewed journal that has received 100 or more citations from other articles also published in peer-reviewed journals. This study aimed to determine patterns of citation classics changes in the medical field otorhinolaryngology and head and neck surgery (OHNS) over the past decade and serves as a follow-up to an original study published in 2002, "A Century of Citation Classics in Otolaryngology-Head & Neck Surgery." Bibliometric analysis. Using the Journal Citation Reports and Web of Science, OHNS journals were selected and assessed for the content of citation classics. Nine-hundred five citation classics were found, over 11-fold more than 1 decade prior. Other significant changes were seen in country of origin, decade of publication, number of authors per article, subspecialty of article, and most frequently discussed topics. The dramatic rise in quantity and nature of citation classics in the past decade may be due to unprecedented advancements in information technology and communication, allowing studies and experiments to be performed, written, reviewed, published, and cited at rapid rates.

    Full Text Available Citations for randomized controlled trials (RCT are important for the dissemination of study results. However, predictors of citations for RCTs have not been investigated. The study aimed to investigate the predictors of citations for RCTs in sepsis literature. RCTs that investigated the efficacy of treatment strategies on clinical outcomes in sepsis patients were included, and publication dates were restricted to the period from 2000 to 2016. Risk of bias was assessed using the Cochrane handbook for systematic reviews and interventions. A multivariable linear regression model was built to investigate the independent variables associated with total citations. In total, 160 RCTs met our inclusion criteria and were included for analysis. The median of total citations was 28.5 (IQR: 6-76. The journal impact factor (IF for articles was 6.312 (IQR: 3.143-7.214. The dependent variable was transformed by the square root to improve normality and meet the assumption of homoscedasticity. The journal IF (coefficient: 0.2; 95% CI: 0.16, 0.25 was independently associated with total citations. Large samples were associated with more total citations (coefficient: 0.0026; 95% CI: 0.0013, 0.0039. The study demonstrated that the journal IF was a major determinant of the RCT's total citation number.

    To identify and analyze the characteristics of the most influential articles about central nervous system (CNS) inflammatory demyelinating disease. The Institute for Scientific Information (ISI) Web of Science database and the 2014 Journal Citation Reports Science Edition were used to retrieve the top 100 cited articles on CNS inflammatory demyelinating disease. The citation numbers, journals, years of publication, authorships, article types, subjects and main issues were analyzed. For neuromyelitis optica (NMO), articles that were cited more than 100 times were regarded as a citation classic and described separately. The top 100 cited articles were published between 1972 and 2011 in 13 journals. The highest number of articles ( n  = 24) was published in Brain, followed by The New England Journal of Medicine ( n  = 21). The average number of citations was 664 (range 330-3,897), and 64% of the articles were from the United States and the United Kingdom. The majority of the top 100 cited articles were related to multiple sclerosis ( n  = 87), and only a few articles reported on other topics such as NMO ( n  = 9), acute disseminated encephalomyelitis ( n  = 2) and optic neuritis ( n  = 2). Among the top 100 cited articles, 77% were original articles. Forty-one citation classics were found for NMO. Our study provides a historical perspective on the research progress on CNS inflammatory demyelinating disease and may serve as a guide for important advances and trends in the field for associated researchers.

  20. The e-index, complementing the h-index for excess citations.

    Directory of Open Access Journals (Sweden)

    Chun-Ting Zhang

    Full Text Available BACKGROUND: The h-index has already been used by major citation databases to evaluate the academic performance of individual scientists. Although effective and simple, the h-index suffers from some drawbacks that limit its use in accurately and fairly comparing the scientific output of different researchers. These drawbacks include information loss and low resolution: the former refers to the fact that in addition to h(2 citations for papers in the h-core, excess citations are completely ignored, whereas the latter means that it is common for a group of researchers to have an identical h-index. METHODOLOGY/PRINCIPAL FINDINGS: To solve these problems, I here propose the e-index, where e(2 represents the ignored excess citations, in addition to the h(2 citations for h-core papers. Citation information can be completely depicted by using the h-index together with the e-index, which are independent of each other. Some other h-type indices, such as a and R, are h-dependent, have information redundancy with h, and therefore, when used together with h, mask the real differences in excess citations of different researchers. CONCLUSIONS/SIGNIFICANCE: Although simple, the e-index is a necessary h-index complement, especially for evaluating highly cited scientists or for precisely comparing the scientific output of a group of scientists having an identical h-index.

    Conceptual frameworks are recommended as a way of applying theory to enhance implementation efforts. The Knowledge to Action (KTA) Framework was developed in Canada by Graham and colleagues in the 2000s, following a review of 31 planned action theories. The framework has two components: Knowledge Creation and an Action Cycle, each of which comprises multiple phases. This review sought to answer two questions: 'Is the KTA Framework used in practice? And if so, how?' This study is a citation analysis and systematic review. The index citation for the original paper was identified on three databases-Web of Science, Scopus and Google Scholar-with the facility for citation searching. Limitations of English language and year of publication 2006-June 2013 were set. A taxonomy categorising the continuum of usage was developed. Only studies applying the framework to implementation projects were included. Data were extracted and mapped against each phase of the framework for studies where it was integral to the implementation project. The citation search yielded 1,787 records. A total of 1,057 titles and abstracts were screened. One hundred and forty-six studies described usage to varying degrees, ranging from referenced to integrated. In ten studies, the KTA Framework was integral to the design, delivery and evaluation of the implementation activities. All ten described using the Action Cycle and seven referred to Knowledge Creation. The KTA Framework was enacted in different health care and academic settings with projects targeted at patients, the public, and nursing and allied health professionals. The KTA Framework is being used in practice with varying degrees of completeness. It is frequently cited, with usage ranging from simple attribution via a reference, through informing planning, to making an intellectual contribution. When the framework was integral to knowledge translation, it guided action in idiosyncratic ways and there was theory fidelity. Prevailing wisdom

    Full Text Available BACKGROUND: Many patients' and consumers' organizations accept drug industry funding to support their activities. As drug companies and patient groups move closer, disclosure become essential for transparency, and the internet could be a useful means of making sponsorship information accessible to the public. This survey aims to assess the transparency of a large group of Italian patient and consumer groups and a group of pharmaceutical companies, focusing on their websites. METHODOLOGY/PRINCIPAL FINDINGS: Patient and consumer groups were selected from those stated to be sponsored by a group of pharmaceutical companies on their websites. The websites were examined using two forms with principal (name of drug companies providing funds, amount of funding and secondary indicators of transparency (section where sponsors are disclosed, update of sponsorship. Principal indicators were applied independently by two reviewers to the patient and consumer groups' websites. Discordances were solved by discussion. One hundred fifty-seven Italian patient and consumer groups and 17 drug companies were considered. Thirteen drug companies (76% named at least one group funded, on their Italian websites. Of these, four (31% indicated the activities sponsored and two (15% the amount of funding. Of the 157 patient and consumer groups, 46 (29% named at least one pharmaceutical company as providing funds. Three (6% reported the amount of funding, 25 (54% the activities funded, none the proportion of income derived from drug companies. Among the groups naming pharmaceutical company sponsors, 15 (33% declared them in a dedicated section, five (11% on the home page, the others in the financial report or other sections. CONCLUSIONS/SIGNIFICANCE: Disclosure of funds is scarce on Italian patient and consumer groups' websites. The levels of transparency need to be improved. Disclosure of patient and consumer groups provided with funds is frequent on Italian pharmaceutical

  5. Currencies of Science: discussing disciplinary “exchange rates” for citations and Mendeley readership

    2016-07-01

    In 1998 Garfield stated that “[t]he Mertonian description of normal science describes citations as the currency of science. Scientists make payments, in the form of citations, to their preceptors”. The idea of citations as a currency of science was also discussed by Wouters (1999) who suggested that the “role of the citation might also be compared with that of money, especially if the evaluative use of scientometrics is taken into account. Whenever the value of an article is expressed in its citation frequency, the citation is probably the most important unit of a ‘currency of science’”. Thus, citations have been seen as currency able to reward scientists for their work and scientific merit, being an integral part, together with authorship and acknowledgements, of the so-called “reward triangle” (Cronin & Weaver, 1995)2. This role of citations as main currency in evaluative scientometrics has gone unchallenged until recently. The emergence of new ways of measuring the reception of scientific publications by different audiences in the form of the so-called “altmetrics” (Haustein, et al. 2015a; Priem, et al. 2010) probably represents the most important attempt of expanding the system of currencies of science. However, research on altmetrics suggest that there are critical differences with citations: in coverage (Thelwall, et al. 2013), main characteristics (Haustein, et al., 2015), correlations (Costas, et al. 2015b; Haustein, et al. 2014), and interpretation (Haustein et al., 2016). These results essentially highlight the limited potential of most of these metrics as realistic alternatives to citations. (Author)

  6. Citation indexing and evaluation of scientific papers.

    Science.gov (United States)

    Margolis, J

    1967-03-10

    Evaluation by means of citation patterns can be successful only insofar as published papers and their bibliographies reflect scientific activity and nothing else. Such an innocent descrip tion is becoming less and less tenable. The present scientific explosion gave rise to more than a proportional pub lication explosion, which not only re flects the scientific explosion but has its own dynamics and vicious circles. Publication of results is probably the main means of accomplishing the al most impossible task of accounting for time and money spent on research. Inevitably, this puts a premium on quantity at the expense of quality, and, as with any other type of inflation, the problem worsens: the more papers are written, the less they count for and the greater is the pressure to publish more. What makes matters worse is the fact that the sheer volume of the"litera ture" makes it increasingly difficult to separate what is worthwhile from the rest. Critical reviews have become somewhat of a rarity, and editorial judgment is usually relegated to ref erees, who are contemporaries and, per haps, competitors of the authors-a situation which has its own undesirable implications (11, 18). It requires little imagination to discover other vicious circles, all arising from distortion of the primary reasons for publishing the results of scientific inquiry. There are, it is true, signs of ad justment to this crisis, partly due to some easing of the pressure to pub lish at all costs, and partly due to the readers' changing attitudes toward the flood of publications. An increasing amount of research is now being car ried out in the form of collective proj ects in large institutions where publica tion is no longer the standard method of accounting for individual work. At the same time there is apparent an in creasing tendency for scientific journals to polarize into the relatively few leading ones which carry important informa tion and the many subsidiary journals which serve as

    Citation rate is one of several tools to measure academic productivity. The purposes of this study were to estimate and identify factors associated with citation rates in the oral and maxillofacial surgery (OMS) literature. This was a retrospective longitudinal study of publications in the Journal of Oral and Maxillofacial Surgery (JOMS), International Journal of Oral and Maxillofacial Surgery (IJOMS), and Oral Surgery, Oral Medicine, Oral Pathology, and Oral Radiology (OOOO) from January through December 2012. The predictor variables were author- and article-specific factors. The outcome variable was the citation rate, defined as the total number of citations for each article over a 4-year period. Descriptive, bivariate, and multiple regression statistics were computed. The authors identified 993 articles published during 2012. The mean number of citations at 4 years after publication was 5.6 ± 5.3 (median, 4). In bivariate analyses, several author- and article-specific factors were associated with citation rates. In a multiple regression model adjusting for potential confounders and effect modifiers, first author H-index, number of authors, journal, OMS focus area, and Oxford level of evidence were significantly associated with citation rate (P ≤ .002). The authors identified 5 factors associated with citation rates in the OMS literature. These factors should be considered in context when evaluating citation-based metrics for OMS. Studies that focus on core OMS procedures (eg, dentoalveolar surgery, dental implant surgery), are published in specialty-specific journals (eg, JOMS or IJOMS), and have higher levels of evidence are more likely to be cited.

    Full Text Available Memes are the cultural equivalent of genes that spread across human culture by means of imitation. What makes a meme and what distinguishes it from other forms of information, however, is still poorly understood. Our analysis of memes in the scientific literature reveals that they are governed by a surprisingly simple relationship between frequency of occurrence and the degree to which they propagate along the citation graph. We propose a simple formalization of this pattern and validate it with data from close to 50 million publication records from the Web of Science, PubMed Central, and the American Physical Society. Evaluations relying on human annotators, citation network randomizations, and comparisons with several alternative approaches confirm that our formula is accurate and effective, without a dependence on linguistic or ontological knowledge and without the application of arbitrary thresholds or filters.

    2014-09-01

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

    A recent review of technical editing of research suggests that over one third of references cited in articles in medical journals have some inaccuracies and one fifth of quotations to references in these articles are not accurate. Two hundred and forty-nine citation references and 408 quotes from 25 articles published in 5 orthopaedic journals were randomly selected to determine referencing accuracy. The presence of citation errors was examined by 1 of the authors while the presence of quotation errors was determined by 2 of the authors. Full copies of articles as well as the references were obtained to compare the accuracies. The total citation error rate was 41% (103 out of 249 references), and the total quotation error rate was 20% (80 out of 408 quotes) for the 5 orthopaedic journals. Citation and quotation errors were still relatively common in orthopaedic journals. While we did not identify any factors associated with citation and quotation errors, the use of technical editing may reduce the amount of citation errors. Readers and authors should be aware that many citations of studies are inaccurate and one should review the original source if it is to be used in another publication or to guide clinical treatment.

    Level of evidence (LOE) hierarchies rank scientific articles according to the use of study design features intended to limit bias. Citation analysis of medical articles has shown that studies with high LOE ranking are preferentially cited. To determine whether clinical companion animal articles reporting study designs classified as high LOE are more frequently cited than those with designs classified as low LOE and to characterize other factors associated with 5-year citation rate. Literature survey of all original clinical articles published in 2004 in 5 peer-reviewed clinical veterinary journals. For each eligible article, details of scientific and nonscientific characteristics were collected, an LOE classification was assigned, and the 5-year citation rate following publication was determined. Linear regression was used to identify factors associated with citation rate. Overall LOE was low with 188 of 209 eligible articles describing a study design classified as low LOE. An association was not identified between 5-year citation frequency and LOE classification or any specific feature of study methodology. Articles pertaining to infectious disease or published in the Journal of Veterinary Internal Medicine were associated with significantly greater subsequent citations. Reports of veterinary studies designed to limit the influence of bias are not more widely referenced than articles reporting data obtained through less stringent methodologies. Medical subspecialty and publishing journal prestige can influence an article's subsequent citation rate. Copyright © 2012 by the American College of Veterinary Internal Medicine.

    To evaluate whether completeness of reporting of systematic reviews and meta-analyses in major radiology journals has changed since publication of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement; a secondary objective is to evaluate whether completeness of reporting (ie, PRISMA) is associated with study quality (ie, Assessing the Methodological Quality of Systematic Reviews [AMSTAR]). Systematic reviews and meta-analyses published in major radiology journals between January 2007 and December 2011 were identified by searching MEDLINE with the modified Montori method. Studies were reviewed independently by two investigators and assessed for adherence to the AMSTAR and PRISMA checklists. The average results were analyzed to assess for change in mean score before and after PRISMA publication and to assess results over time; a Pearson correlation coefficient was calculated to assess for any association between PRISMA and AMSTAR results. Included were 130 studies from 11 journals. Average PRISMA and AMSTAR results were 21.8 of 27 and 7.2 of 11, respectively. The average result was higher after publication of PRISMA, and PRISMA-reported items were 22.6 of 27 after publication of PRISMA versus 20.9 of 27 before publication of PRISMA; AMSTAR results were 7.7 of 11 after publication of PRISMA versus 6.7 of 11 before publication of PRISMA. There was a strong positive correlation (r = 0.86) between the PRISMA and AMSTAR results. There was high variability between journals. Radiology had the highest PRISMA reported items (24.7 of 27), and American Journal of Neuroradiology had the lowest (19.6 of 27). Two major areas for improvement include study protocol registration and assessment of risk of bias across studies (ie, publication bias). In major radiology journal studies, there was modest improvement in completeness of reporting of systematic reviews and meta-analyses, assessed by PRISMA, which was strongly associated with higher study

    There are numerous drivers that motivate completion of community health improvement plans (CHIPs). Some are more obvious and include voluntary public health accreditation, state requirements, federal and state funding, and nonprofit hospital requirements through IRS regulations. Less is known about other drivers, including involvement of diverse partners and belief in best practices, that may motivate CHIP completion. This research investigated the drivers that motivated CHIP completion based on experiences of 51 local public health agencies (LPHAs). An explanatory mixed-methods design, including closed- and open-ended survey questions and key informant interviews, was used to understand the drivers that motivated CHIP completion. Analysis of survey data involved descriptive statistics. Classical content analysis was used for qualitative data to clarify survey findings. The surveys and key informant interviews were conducted in the Rocky Mountain Region and Western Plains among 51 medium and large LPHAs in Colorado, Kansas, Montana, Nebraska, North Dakota, South Dakota, Utah, and Wyoming. More than 50% of respondents were public health directors; the balance of the respondents were division/program directors, accreditation coordinators, and public health planners. CHIP completion. Most LPHAs in the Rocky Mountains and Western Plains have embraced developing and publishing a CHIP, with 80% having completed their plan and another 13% working on it. CHIP completion is motivated by a belief in best practices, with LPHAs and partners seeing the benefit of quality improvement activities linked to the CHIP and the investment of nonprofit hospitals in the process. Completing a CHIP is strengthened through engagement of diverse partners and a well-functioning partnership. The future of CHIP creation depends on LPHAs and partners investing in the CHIP as a best practice, dedicating personnel to CHIP activities, and enhancing leadership skills to contribute to a synergistic

    Knowledge development depends on an unbiased representation of the available evidence. Selective citation may distort this representation. Recently, some controversy emerged regarding the possible impact of swimming on childhood asthma, raising the question about the role of selective citation in this field. Our objective was to assess the occurrence and determinants of selective citation in scientific publications on the relationship between swimming in chlorinated pools and childhood asthma. We identified scientific journal articles on this relationship via a systematic literature search. The following factors were taken into account: study outcome (authors' conclusion, data-based conclusion), other content-related article characteristics (article type, sample size, research quality, specificity), content-unrelated article characteristics (language, publication title, funding source, number of authors, number of affiliations, number of references, journal impact factor), author characteristics (gender, country, affiliation), and citation characteristics (time to citation, authority, self-citation). To assess the impact of these factors on citation, we performed a series of univariate and adjusted random-effects logistic regressions, with potential citation path as unit of analysis. Thirty-six articles were identified in this network, consisting of 570 potential citation paths of which 191 (34%) were realized. There was strong evidence that articles with at least one author in common, cited each other more often than articles that had no common authors (odds ratio (OR) 5.2, 95% confidence interval (CI) 3.1-8.8). Similarly, the chance of being cited was higher for articles that were empirical rather than narrative (OR 4.2, CI 2.6-6.7), that reported a large sample size (OR 5.8, CI 2.9-11.6), and that were written by authors with a high authority within the network (OR 4.1, CI 2.1-8.0). Further, there was some evidence for citation bias: articles that confirmed the

  20. Developing Data Citations from Digital Object Identifier Metadata

    NASA's Earth Science Data and Information System (ESDIS) Project has been processing information for the registration of Digital Object Identifiers (DOI) for the last five years of which an automated system has been in operation for the last two years. The ESDIS DOI registration system has registered over 2000 DOIs with over 1000 DOIs held in reserve until all required information has been collected. By working towards the goal of assigning DOIs to the 8000+ data collections under its management, ESDIS has taken the first step towards facilitating the use of data citations with those products. When registering DOIs, ESDIS requires certain DOI elements be collected for the DOI landing page as recommended by NASA's Earth Science Data System Working Group (ESDSWG). The landing page provides sufficient information to 1) identify NASA data as referenced in a science publication, 2) credit data creators and distributors, and 3) access the data itself enabling the trace-ability and reproducibility of the data. However, the required elements for this DOI landing page are also the core required elements for forming an Earth science data citation. Data citations are getting significant attention from the scientific community and data centers alike. So to encourage the citing of Earth science data products, each product DOI landing page displays a sample data citation and makes the required citation elements available to DataCite for use in its Data Citation generation tool. This paper will describe that process. ESDIS data centers are constantly developing technologies to better serve the Earth science user community such as Geospatial Interactive Online Visualization ANd aNalysis Infrastructure (GIOVANNI), Land and Atmospheric Near Real-Time Capability for EOS (LANCE), and advanced tools that support virtual data collections, and virtual data products. These all provide easier access to data and make possible the creation of data products with user specified parameters

    Psoriasis is a relevant topic for publication in general medical journals. We conducted a search of the Thomson Reuters' Science Citation using the search term of "psoriasis" in five high-impact general medical journals. All citation classics from 1970 to 2012 were included and each author's total number of citations was summated. A total of 51 citation classics were collected. The most common topic of publication was psoriasis treatment (37), especially biologic agents (16). A total of 1037 authors of psoriasis articles were identified in our study and the top 25 most-cited authors were compiled. We hope our citation analysis provides a historical perspective and highlights the work of our colleagues and predecessors.

    Citation analysis has become an important tool for research performance assessment in the medical sciences. However, different areas of medical research may have considerably different citation practices, even within the same medical field. Because of this, it is unclear to what extent citation-based bibliometric indicators allow for valid comparisons between research units active in different areas of medical research. A visualization methodology is introduced that reveals differences in citation practices between medical research areas. The methodology extracts terms from the titles and abstracts of a large collection of publications and uses these terms to visualize the structure of a medical field and to indicate how research areas within this field differ from each other in their average citation impact. Visualizations are provided for 32 medical fields, defined based on journal subject categories in the Web of Science database. The analysis focuses on three fields: Cardiac & cardiovascular systems, Clinical neurology, and Surgery. In each of these fields, there turn out to be large differences in citation practices between research areas. Low-impact research areas tend to focus on clinical intervention research, while high-impact research areas are often more oriented on basic and diagnostic research. Popular bibliometric indicators, such as the h-index and the impact factor, do not correct for differences in citation practices between medical fields. These indicators therefore cannot be used to make accurate between-field comparisons. More sophisticated bibliometric indicators do correct for field differences but still fail to take into account within-field heterogeneity in citation practices. As a consequence, the citation impact of clinical intervention research may be substantially underestimated in comparison with basic and diagnostic research.

    To evaluate the production and utilization of Cochrane systematic reviews(CSRs) and to analyze its influential factors, so as to improve the capacity of translating CSRs into practice. All CSRs and protocols were retrieved from the Cochrane Library ISSUE 2, 2011 and citation data were retrieved from SCI database. Citation analysis was used to analyze the situation of CSRs production and utilization. CSR publication had grown from an annual average of 32 to 718 documents. Only one developing country was among the ten countries with the largest amount of publications. High income countries accounted for 83% of CSR publications and 90.8% of cited counts. 34.7% of CSRs had a cited count of 0, while only 0.9% had been cited more than 50 times. Highly cited CSRs were published in England, Australia, Canada, USA and other high income countries. The countries with a Cochrane center or a Cochrane methodology group had a greater capability of CSRs production and citing than others. The CSRs addressing the topics of diseases were more than those targeted at public health issues. There was a big gap in citations of different interventions even for the same topic. The capability of CSR production and translation grew rapidly, but varied among countries and institutions, which was affected by several factors such as the capability of research, the resourcesand the applicability of the evidence. It is important to improve evidence translation through educating, training and prioritizing the problems based on real demands of end user. This article is protected by copyright.

    2008-01-01

    This study provides an overview of the research performance of major European countries in the field Oncology, the most important journals in which they published their research articles, and the most important academic institutions publishing them. The analysis was based on Thomson Scientific's Web of Science (WoS) and calculated bibliometric indicators of publication activity and actual citation impact. Studying the time period 2000-2006, it gives an update of earlier studies, but at the same time it expands their methodologies, using a broader definition of the field, calculating indicators of actual citation impact, and analysing new and policy relevant aspects. Findings suggest that the emergence of Asian countries in the field Oncology has displaced European articles more strongly than articles from the USA; that oncologists who have published their articles in important, more general journals or in journals covering other specialties, rather than in their own specialist journals, have generated a relatively high actual citation impact; and that universities from Germany, and--to a lesser extent--those from Italy, the Netherlands, UK, and Sweden, dominate a ranking of European universities based on number of articles in oncology. The outcomes illustrate that different bibliometric methodologies may lead to different outcomes, and that outcomes should be interpreted with care.

    Article retraction in research is rising, yet retracted articles continue to be cited at a disturbing rate. This paper presents an analysis of recent retraction patterns, with a unique emphasis on the role author self-cites play, to assist the scientific community in creating counter-strategies. This was accomplished by examining the following: (1) A categorization of retracted articles more complete than previously published work. (2) The relationship between citation counts and after-retraction self-cites from the authors of the work, and the distribution of self-cites across our retraction categories. (3) The distribution of retractions written by both the author and the editor across our retraction categories. (4) The trends for seven of our nine defined retraction categories over a 6-year period. (5) The average journal impact factor by category, and the relationship between impact factor, author self-cites, and overall citations. Our findings indicate new reasons for retractions have emerged in recent years, and more editors are penning retractions. The rates of increase for retraction varies by category, and there is statistically significant difference of average impact factor between many categories. 18 % of authors self-cite retracted work post retraction with only 10 % of those authors also citing the retraction notice. Further, there is a positive correlation between self-cites and after retraction citations.

    A citation analysis of biomedical and health sciences journals was conducted based on their enlistment in journal databases to identify the factors contributing to the citation metrics. Among the 1,219 academic journals managed by the National Center for Medical Information and Knowledge at the Korea Centers for Disease Control and Prevention, 556 journals were included for analysis as of July 2016. The characteristics of the journals include history years, publication media, language, open-access policy as well as the status enlisted in international and domestic databases, such as Science Citation Index (SCI), Scopus, Medline, PubMed Central, Embase, and Korea Citation Index (KCI). Six bibliometric measures were collected from SCI, Scopus, and KCI as of 2015, the most recent disclosure year. Analyses of group differences and influential factors were conducted using t -tests, Mann-Whitney tests, and multiple regression. Journal characteristics, such as history years, publication media, and open-access policy, were not significant factors influencing global or domestical citation of the journals. However, global citations were higher for SCI and Medline enlisted journals than for their counterparts. Among KCI journals, the KCI impact factors of journals published in English only were lower. Efforts by journals to be enlisted in international databases, especially in SCI and Medline, are critical to enhance their global circulation. However, articles published in English only hinder the use of domestic researchers. Different strategies are required for enhancing international and domestic readerships.

    2014-08-19

    The citation frequency of a publication is often interpreted as an expression of its scientific impact. Previous citation analyses of Norwegian medical research have either focused on universities and university hospitals or on subject areas at the national level. Such analyses have paid little attention to other health enterprises, despite a strong increase in their research activity during the last decade. For all health enterprises with more than 25 publications in the Web of Science during the period 2005-2011 we have calculated field normalized citation indexes at the institution and subject levels. On the whole, research undertaken by the health enterprises is frequently cited, and some medium-sized health enterprises stand out in terms of their high average citation indexes: Helse Stavanger Health Enterprise, Diakonhjemmet Hospital and Helse Nord-Trøndelag Health Enterprise, although Oslo University Hospital Health Enterprise and Helse Bergen Health Enterprise account for more than half of the most cited articles. In citation analyses at the aggregated level, highly and infrequently cited research groups/departments may balance each other. This appears to be the case in the largest health enterprises. Some medium-sized health enterprises that have a more concentrated research portfolio will thus accumulate higher average citation indexes than the largest university hospitals.

  9. CITATION ANALYSIS OF URBAN PLANNING SCHOLARS IN THE U.S.

    2015-03-01

    Full Text Available This article provides a complete citation analysis for the field of urban planning in the U.S. Urban planning is multi-disciplinary with a rich tradition of debate about the knowledge domain of both research and practice. Urban planning includes consideration of social, economic, technological, environmental, and political systems that are highly sophisticated, which therefore has an extensive body of scholarship. The article argues that Google Scholar is an appropriate source of citation data for urban planning and includes a brief example of one urban planning scholar to demonstrate GS citation patterns. This is followed by the results of a descriptive analysis showing general patterns of citation activity for urban planning schools. A greater depth of analysis is required to better understand the dynamics of these scholarly activities.

    The term "citation classic" has been used in reference to an article that has been cited more than 400 times. The purpose of this study is to identify such articles that pertain to clinical neurosurgery. A list of search phrases relating to neurosurgery was compiled. A topic search was performed using the Institute for Scientific Information Web of Science for phrases. Articles with more than 400 citations were identified, and nonclinical articles were omitted. The journals, year of publication, topics, and study types were analyzed. There were 106 articles with more than 400 citations relating to clinical neurosurgery. These articles appeared in 28 different journals, with more than half appearing in the Journal of Neurosurgery or the New England Journal of Medicine. Fifty-three articles were published since 1990. There were 38 articles on cerebrovascular disease, 21 on stereotactic and functional neurosurgery, 21 on neurooncology, 19 on trauma, 4 on nontraumatic spine, 2 on CSF pathologies, and 1 on infection. There were 29 randomized trials, of which 86% appeared in the New England Journal of Medicine, Lancet, or the Journal of the American Medical Association, and half concerned the prevention or treatment of stroke. In addition, there were 16 prospective studies, 15 classification or grading systems, and 7 reviews. The remaining 39 articles were case series, case reports, or technical notes. More than half of the citation classics identified in this study have been published in the past 20 years. Case series, classifications, and reviews appeared more frequently in neurosurgical journals, while randomized controlled trials tended to be published in general medical journals.

  14. Improving MeSH classification of biomedical articles using citation contexts.

    2011-10-01

    Medical Subject Headings (MeSH) are used to index the majority of databases generated by the National Library of Medicine. Essentially, MeSH terms are designed to make information, such as scientific articles, more retrievable and assessable to users of systems such as PubMed. This paper proposes a novel method for automating the assignment of biomedical publications with MeSH terms that takes advantage of citation references to these publications. Our findings show that analysing the citation references that point to a document can provide a useful source of terms that are not present in the document. The use of these citation contexts, as they are known, can thus help to provide a richer document feature representation, which in turn can help improve text mining and information retrieval applications, in our case MeSH term classification. In this paper, we also explore new methods of selecting and utilising citation contexts. In particular, we assess the effect of weighting the importance of citation terms (found in the citation contexts) according to two aspects: (i) the section of the paper they appear in and (ii) their distance to the citation marker. We conduct intrinsic and extrinsic evaluations of citation term quality. For the intrinsic evaluation, we rely on the UMLS Metathesaurus conceptual database to explore the semantic characteristics of the mined citation terms. We also analyse the "informativeness" of these terms using a class-entropy measure. For the extrinsic evaluation, we run a series of automatic document classification experiments over MeSH terms. Our experimental evaluation shows that citation contexts contain terms that are related to the original document, and that the integration of this knowledge results in better classification performance compared to two state-of-the-art MeSH classification systems: MeSHUP and MTI. Our experiments also demonstrate that the consideration of Section and Distance factors can lead to statistically

    Citation analysis provides insights into the history and developmental trajectory of scientific fields. Our objective was to perform an analysis of citation classics in the journals of pediatric specialty and to examine their characteristics. Initially, all the journals listed under the category of pediatrics (n = 120) were identified using Journal Citation Reports. Web of science database was then searched (1950-2016) to select the top-100 cited articles in the above identified pediatric journals. The top-100 cited article were categorized according the study design, sub-specialty, country, institutional affiliation, and language. The top-100 articles were published in 18 different journals, with Pediatrics having the highest numbers (n = 40), followed by The Journal of Pediatrics (n = 17). The majority (n = 62) of classics were published after 1990. The most cited article had citation count of 3516 and the least cited had a citation count of 593. The USA (n = 71) was the most commonly represented country, and 60 institutions contributed to 100 articles. Fifteen authors contributed to more than one classic as first or second author. Observational study (n = 55) was the commonest study design across all decades, followed by reviews (n = 12), scale development studies (n = 11), and guidelines (n = 11). Among the pediatric sub-specialties, growth and development articles were highly cited (n = 24), followed by pediatric psychiatry and behavior (n = 21), endocrinology (n = 15), and neonatology (n = 12). The top-100 cited articles in pediatrics identify the impactful authors, journals, institutes, and countries. Observational study design was predominant-implying that inclusion among citation classics is not related to soundness of study design.

    Citation analysis-the exploration of reference patterns in the scholarly and scientific literature-has long been applied in a number of social sciences to study research impact, knowledge flows, and knowledge networks. It has important information science applications as well, particularly in knowledge representation and in information retrieval.Recent years have seen a burgeoning interest in citation analysis to help address research, management, or information service issues such as university rankings, research evaluation, or knowledge domain visualization. This renewed and growing interest

    Concerns have been raised regarding the impact factor's (IF) accuracy and credibility, which may be affected by different factors, including self-citations. To investigate the self-citation rate (SCR) of dermatology journals and its relationship to the IF. Data on all dermatology journals listed in the Journal Citation Reports (JCR) were retrieved, and the following parameters were analyzed: IF, total publications used to calculate the IF, total citations used to calculate the IF, self-citations used to calculate the IF, SCR, and IF without self-citations (corrected IF). The median SCR was 10.53% (0-50%), and the median IF and corrected IF, 1.54 (0.05-6.37) and 1.35 (0.03-5.84), respectively. There was an inverse correlation between the IF and the SCR. A statistically significant difference was noted in the SCR between general and subspecialty journals and between journals that offered a full English text and those that did not. In general, the IF of dermatology journals is not influenced by the SCR. However, journals with a lower IF tend to have a higher SCR. Subspecialty journals and foreign language journals have a higher SCR than general dermatology and English language journals, respectively, probably owing to their limited distribution and the difficulty experienced by international authors in accessing references in specific languages. © 2015 The International Society of Dermatology.

  18. PREP-45, Input Preparation for CITATION-2

    International Nuclear Information System (INIS)

    1 - Description of program or function: A Fortran program has been created, which saves much effort in preparing sections 004 (intervals in the coordinates) and 005 (zone numbers) of the input data file for the multigroup theory code CITATION (version CITATION-2, NESC0387/09), particularly when a thin complicated mesh is used. 2 - Method of solution: A domain is defined for CITATION calculations through specifying its sub-domains (e.g. graphite, lead, beryllium, water and fuel sub-domains) in a compact and simple way. An independent and previous geometrical specification is made of the various types of elements which are envisaged to constitute the contents of the reactor core grid positions. Then the load table for the configuration is input and scanned throughout, thus enabling the geometric mesh description to be produced (section 004). Also the zone placement (section 005) is achieved by means of element description subroutines for the different types of element (which may require appropriate but simple changes in the actual cases). The output of PREP45 is directly obtained in a format which is compatible with CITATION-2 input. 3 - Restrictions on the complexity of the problem: Only rectangular two-dimensional Cartesian coordinates are considered. A maximum of 12 sub-domains in the x direction (18 in the y direction) and up to 8 distinct element types are considered in this version. Other limitations exist which can nevertheless be overcome with simple changes in the source program

    The purpose of this study was to identify and review the most cited articles in the occupational therapy field. Using the multi-disciplinary Publish or Perish software to extract data, the top 50 lifetime and annual cited articles were examined. Studies were organized according to the following: year of publication, design, topic, number of authors, country of publication, and number of citations for each cohort. We found that randomized control trials were the dominant design type used in papers with the most lifetime (36.0%) and annual (26.0%) citations. Additionally, in both groups, the most frequently cited articles investigated predictors of functional outcome for patients. This comprehensive citation analysis will inform future research through its identification of major trends and well-established areas of study.

  1. Analyzing Data Citations to Assess the Scientific and Societal Value of Scientific Data

    Stakeholders in the creation, distribution, support, funding, and use of scientific data can benefit by understanding the value that the data have for society and science. For decades, the scientific community has been using citations of articles in the published scientific literature as one of the primary measures used for evaluating the performance of scientists, departments, institutions, and scientific disciplines. Similarly, citations in the published literature of scientific data may be useful for measuring and assessing the value of the scientific data and the performance of the individuals, projects, programs, and organizations that have contributed to the data and their use. The results of citation analysis and other assessments of the value of data also can contribute to planning for future data collection, development, distribution, and preservation efforts. The planned release of new data citation indexes and the more widespread adoption of unique data identifiers and automated attribution mechanisms have the potential to improve significantly the capabilities for analyzing citations of scientific data. In addition, rapid developments in the systems and capabilities for disseminating data, along with education and workforce development on the importance of data attribution and on techniques for data citation, can improve practices for citing scientific data. Such practices need to lead not only to better aggregate statistics about data citation, but also to improved characterization and understanding of the impact of data use in terms of the benefits for science and society. Analyses of citations in the scientific literature were conducted for data that were distributed by an interdisciplinary scientific data center during a five-year period (1997 - 2011), to identify the scientific fields represented by the journals and books in which the data were cited. Secondary citation analysis also was conducted for a sample of scientific publications that used

    During Eugene Garfield's (EG's) lengthy career as information scientist, he published about 1500 papers. In this study, we use the impressive oeuvre of EG to introduce a new type of bibliometric networks: keyword co-occurrences networks based on the context of citations, which are referenced in a certain paper set (here: the papers published by EG). The citation context is defined by the words which are located around a specific citation. We retrieved the citation context from Microsoft Academic. To interpret and compare the results of the new network type, we generated two further networks: co-occurrence networks which are based on title and abstract keywords from (1) EG's papers and (2) the papers citing EG's publications. The comparison of the three networks suggests that papers of EG and citation contexts of papers citing EG are semantically more closely related to each other than to titles and abstracts of papers citing EG. This result accords with the use of citations in research evaluation that is based on the premise that citations reflect the cognitive influence of the cited on the citing publication.

    The preferential citation of studies with the highest success rates could exaggerate perceived effectiveness, particularly for treatments with widely varying published success rates such as radiofrequency catheter ablation for atrial fibrillation. We systematically identified observational studies and clinical trials of radiofrequency catheter ablation of atrial fibrillation between 1990 and 2012. Generalized Poisson regression was used to estimate association between study success rate and total citation count, adjusting for sample size, journal impact factor, time since publication, study design, and whether first or last author was a consensus-defined pre-eminent expert. We identified 174 articles meeting our inclusion criteria (36 289 subjects). After adjustment only for time since publication, a 10-point increase above the mean in pooled reported success rates was associated with a 17.8% increase in citation count at 5 years postpublication (95% confidence interval, 7.1-28.4%; Pcitation count; 95% confidence interval, 7.6-29.6%; Pcitation count, which may indicate citation bias. To readers of the literature, radiofrequency catheter ablation of atrial fibrillation could be perceived to be more effective than the data supports. These findings may have implications for a wide variety of novel cardiovascular therapies. © 2014 American Heart Association, Inc.

  4. Using incomplete citation data for MEDLINE results ranking.

    Information overload is a significant problem for modern medicine. Searching MEDLINE for common topics often retrieves more relevant documents than users can review. Therefore, we must identify documents that are not only relevant, but also important. Our system ranks articles using citation counts and the PageRank algorithm, incorporating data from the Science Citation Index. However, citation data is usually incomplete. Therefore, we explore the relationship between the quantity of citation information available to the system and the quality of the result ranking. Specifically, we test the ability of citation count and PageRank to identify "important articles" as defined by experts from large result sets with decreasing citation information. We found that PageRank performs better than simple citation counts, but both algorithms are surprisingly robust to information loss. We conclude that even an incomplete citation database is likely to be effective for importance ranking.

  5. Patterns of citations of open access and non-open access conservation biology journal papers and book chapters.

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

    There are often differences in a publication's citation count, depending on the database accessed. Here, aspects of citation counts for medical physics and biomedical engineering papers are studied using papers published in the journal Australasian physical and engineering sciences in medicine. Comparison is made between the Web of Science, Scopus, and Google Scholar. Papers are categorised into subject matter, and citation trends are examined. It is shown that review papers as a group tend to receive more citations on average; however the highest cited individual papers are more likely to be research papers.

  10. Does Interdisciplinary Research Lead to Higher Citation Impact? The Different Effect of Proximal and Distal Interdisciplinarity

    Science.gov (United States)

    Yegros-Yegros, Alfredo; Rafols, Ismael; D’Este, Pablo

    2015-01-01

    This article analyses the effect of degree of interdisciplinarity on the citation impact of individual publications for four different scientific fields. We operationalise interdisciplinarity as disciplinary diversity in the references of a publication, and rather than treating interdisciplinarity as a monodimensional property, we investigate the separate effect of different aspects of diversity on citation impact: i.e. variety, balance and disparity. We use a Tobit regression model to examine the effect of these properties of interdisciplinarity on citation impact, controlling for a range of variables associated with the characteristics of publications. We find that variety has a positive effect on impact, whereas balance and disparity have a negative effect. Our results further qualify the separate effect of these three aspects of diversity by pointing out that all three dimensions of interdisciplinarity display a curvilinear (inverted U-shape) relationship with citation impact. These findings can be interpreted in two different ways. On the one hand, they are consistent with the view that, while combining multiple fields has a positive effect in knowledge creation, successful research is better achieved through research efforts that draw on a relatively proximal range of fields, as distal interdisciplinary research might be too risky and more likely to fail. On the other hand, these results may be interpreted as suggesting that scientific audiences are reluctant to cite heterodox papers that mix highly disparate bodies of knowledge—thus giving less credit to publications that are too groundbreaking or challenging.

  11. Measuring the Value of Research Data: A Citation Analysis of Oceanographic Data Sets

    Science.gov (United States)

    Belter, Christopher W.

    2014-01-01

    Evaluation of scientific research is becoming increasingly reliant on publication-based bibliometric indicators, which may result in the devaluation of other scientific activities - such as data curation – that do not necessarily result in the production of scientific publications. This issue may undermine the movement to openly share and cite data sets in scientific publications because researchers are unlikely to devote the effort necessary to curate their research data if they are unlikely to receive credit for doing so. This analysis attempts to demonstrate the bibliometric impact of properly curated and openly accessible data sets by attempting to generate citation counts for three data sets archived at the National Oceanographic Data Center. My findings suggest that all three data sets are highly cited, with estimated citation counts in most cases higher than 99% of all the journal articles published in Oceanography during the same years. I also find that methods of citing and referring to these data sets in scientific publications are highly inconsistent, despite the fact that a formal citation format is suggested for each data set. These findings have important implications for developing a data citation format, encouraging researchers to properly curate their research data, and evaluating the bibliometric impact of individuals and institutions.

    2015-01-01

    Despite the use of citation rate as a measure of quality of research is strongly criticized and debated, it remain a widely used method to evaluate performances of researchers, articles and journals. The aim of this study was to test which factors are associated with citation rate of Randomised Controlled Trials (RCTs) published on the physiotherapy field. All RCTs abstracted in the Physiotherapy Evidence Database (PEDro), indexed in Scopus database and published in 2008 were included. PEDro score, language of publication, indexing in PubMed database, type of access to articles, subdiscipline, the number of authors, the country where the study was performed, the type of institution where the study was conducted and the number of centres involved in the study (multicentric vs single-centre). and the 2013 5-year impact factor of the publishing journals were considered as independent variables. Citation rate until December 2013 was extracted from Scopus database and used as dependent variable. Six hundred and nineteen RCTs, published in 283 journals, were included and analysed. The 5-year impact factor was the strongest variable associated with the citation rate and explained approximately 50 % of the variance, and the number of authors explained an additional small part (about 1 %) of variability. The other variables were excluded from the model. The study highlights that 5-year Impact Factor, not accessibility (language of publication, indexing in PubMed database or the type of access to articles) or reported quality (PEDro score), is a strong predictor of the number of citations for RCTs in the physiotherapy field. Our findings support the increasingly widespread idea that citation analysis does not reflect the scientific merit of the cited work, at least in terms of reported quality.The results of this study need to be confirmed with a publication window larger than one year.

    There are no analyses of citations to books on epidemiological and statistical methods in the biomedical literature. Such analyses may shed light on how concepts and methods changed while biomedical research evolved. Our aim was to analyze the number and time trends of citations received from biomedical articles by books on epidemiological and statistical methods, and related disciplines. The data source was the Web of Science. The study books were published between 1957 and 2010. The first year of publication of the citing articles was 1945. We identified 125 books that received at least 25 citations. Books first published in 1980-1989 had the highest total and median number of citations per year. Nine of the 10 most cited texts focused on statistical methods. Hosmer & Lemeshow's Applied logistic regression received the highest number of citations and highest average annual rate. It was followed by books by Fleiss, Armitage, et al., Rothman, et al., and Kalbfleisch and Prentice. Fifth in citations per year was Sackett, et al., Evidence-based medicine. The rise of multivariate methods, clinical epidemiology, or nutritional epidemiology was reflected in the citation trends. Educational textbooks, practice-oriented books, books on epidemiological substantive knowledge, and on theory and health policies were much less cited. None of the 25 top-cited books had the theoretical or sociopolitical scope of works by Cochrane, McKeown, Rose, or Morris. Books were mainly cited to reference methods. Books first published in the 1980s continue to be most influential. Older books on theory and policies were rooted in societal and general medical concerns, while the most modern books are almost purely on methods.

Alastair Pennycook (1996 and Sarah Wakefield (2006 have contributed pieces to the elaborate plagiarism/citation puzzle, while Houston Baker situated the hip-hop DJ in seminal text Black Studies, Rap and the Academy (1993. Merging these moments introduces critical questions: Did Diddy invent “the remix” or become the illest beat-biter ever? How did DJ/Producers Pete Rock and Large Professor pay homage to previous musical genres to further hip-hop remix production without just taking 4-8 bar samples, copying sources and claiming unethical ownership? And how can this discussion provide students a window into citation conversations? This article will remix these “texts” to introduce the idea of DJ Rhetoric to discuss plagiarism. Through the lens of the hip-hop DJ in writing classrooms, one can foster an appreciation of the difference between “love and theft” in student citation. This article will couple examples from hip-hop music/culture while simultaneously remixing interviews from various hip-hop DJ/producers to help answer these difficult questions.

    Recent science of science research shows that scientific impact measures for journals and individual articles have quantifiable regularities across both time and discipline. However, little is known about the scientific impact distribution at the scale of an individual scientist. We analyze the aggregate production and impact using the rank-citation profile c(i)(r) of 200 distinguished professors and 100 assistant professors. For the entire range of paper rank r, we fit each c(i)(r) to a common distribution function. Since two scientists with equivalent Hirsch h-index can have significantly different c(i)(r) profiles, our results demonstrate the utility of the β(i) scaling parameter in conjunction with h(i) for quantifying individual publication impact. We show that the total number of citations C(i) tallied from a scientist's N(i) papers scales as [Formula: see text]. Such statistical regularities in the input-output patterns of scientists can be used as benchmarks for theoretical models of career progress.

    Full Text Available Unique identifiers (UID are seen as an effective tool to create links between identical publications in databases or identify duplicates in a database. The purpose of the present study is to investigate how well UIDs work for citation linking. We have two objectives: Explore the coverage, precision, and characteristics of publications matched versus not matched with UIDs as the match key.   Illustrate how publication sets formed by using UIDs as the match key may affect the bibliometric indicators: Number of publications, number of citations and the average number of citations per publication.   The objectives are addressed in a literature review and a case study. The literature review shows that only a few studies evaluate how well UIDs work as a match key. From the literature we identify four error types: Duplicate digital object identifiers (DOI, incorrect DOIs in reference lists and databases, DOIs not registered by the database where a bibliometric analysis is performed, and erroneous optical or special character recognition.   The case study explores the use of UIDs in the integration between the databases Pure and SciVal. Specifically journal publications in English are matched between the two databases. We find all error types except erroneous optical or special character recognition in our publication sets. In particular the duplicate DOIs constitute a problem for the calculation of bibliometric indicators as both keeping the duplicates to improve the reliability of citation counts and deleting them to improve the reliability of publication counts will distort the calculation of average number of citations per publication.   The use of UIDs as a match key in citation linking is implemented in many settings, and the availability of UIDs may become critical for the inclusion of a publication or a database in a bibliometric analysis.

    Speculation over a global rise in jellyfish populations has become widespread in the scientific literature, but until recently the purported ‘global increase’ had not been tested. Here we present a citation analysis of peer-reviewed literature to track the evolution of the current perception of increases in jellyfish and identify key papers involved in its establishment. Trend statements and citation threads were reviewed and arranged in a citation network. Trend statements were assessed according their degree of affirmation and spatial scale, and the appropriateness of the citations used to support statements was assessed. Analyses showed that 48.9% of publications misinterpreted the conclusions of cited sources, with a bias towards claiming jellyfish populations are increasing, with a single review having the most influence on the network. Collectively, these disparities resulted in a network based on unsubstantiated statements and citation threads. As a community, we must ensure our statements about scientific findings in general are accurately substantiated and carefully communicated such that incorrect perceptions, as in the case of jellyfish blooms, do not develop in the absence of rigorous testing. © 2016 John Wiley & Sons Ltd

    The objective of this study was to identify the 100 most cited, peer-reviewed burn-related articles over the past half century. Burn care presents ongoing challenges to both U.S. civilian and military healthcare personnel. Improvements in burn survival and quality of life are the result of advances in burn research. The Web of Science (including Science Citation Index) was searched for the most cited articles related to burn care, published from 1955 to the present. The most cited article was "Permanent coverage of large burn wounds with autologous cultured human epithelium," by G.G. Gallico et al, New England Journal of Medicine, 1984 (711 citations). Between the 1970s and the 1990s, there was a near doubling of the number of highly cited publications with each subsequent decade. A total of 85% of the articles were on the topics of pathophysiology (37%), wounds, tissue, or dressings (31%), or organ failure/sepsis (17%). B.A. Pruitt Jr. (2320 citations), D.N. Herndon (1972 citations), and A.D. Mason Jr. (1435 citations) were the most cited authors. This study identified some of the most important contributions to burn research and the areas of greatest scientific interest to the specialty during the past five decades, and highlights key research that has contributed to the evolution of modern burn care.

    The aim of the study was to evaluate citation analysis as an approach to measuring core outcome set (COS) uptake, by assessing whether the number of citations for a COS report could be used as a surrogate measure of uptake of the COS by clinical trialists. Citation data were obtained for COS reports published before 2010 in five disease areas (systemic sclerosis, rheumatoid arthritis, eczema, sepsis and critical care, and female sexual dysfunction). Those publications identified as a report of a clinical trial were examined to identify whether or not all outcomes in the COS were measured in the trial. Clinical trials measuring the relevant COS made up a small proportion of the total number of citations for COS reports. Not all trials citing a COS report measured all the recommended outcomes. Some trials cited the COS reports for other reasons, including the definition of a condition or other trial design issues addressed by the COS report. Although citation data can be readily accessed, it should not be assumed that the citing of a COS report indicates that a trial has measured the recommended COS. Alternative methods for assessing COS uptake are needed. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

    The expansion of scientific publications makes more difficult the mining of relevant information necessary for a productive appraisal of authors' work, scientific interaction and exchange. Papers over-citation is unproductive, under-citation of innovative research generates delay and inefficiency. The extraction of information from the literature is mostly based on keywords (KWs). I computed the chances of citation of one paper as 1/number of papers retrieved by the KWs published in that paper, and compared them with the chances obtained by selecting different KWs. Using generic KWs the chances are smaller, at times practically nil, as compared to those calculated with more specific KWs and their association. Selecting scientifically-analyzed KWs, specific for the message conveyed by a paper and computing beforehand the theoretical chances of citation, might increase the citations obtained, the retrieval of important scientific and innovative information, optimize scientific exchange and qualitative productivity.

    Finding eligible studies for meta-analysis and systematic reviews relies on keyword-based searching as the gold standard, despite its inefficiency. Searching based on direct citations is not sufficiently comprehensive. We propose a novel strategy that ranks articles on their degree of co-citation with one or more "known" articles before reviewing their eligibility. In two independent studies, we aimed to reproduce the results of literature searches for sets of published meta-analyses (n = 10 and n = 42). For each meta-analysis, we extracted co-citations for the randomly selected 'known' articles from the Web of Science database, counted their frequencies and screened all articles with a score above a selection threshold. In the second study, we extended the method by retrieving direct citations for all selected articles. In the first study, we retrieved 82% of the studies included in the meta-analyses while screening only 11% as many articles as were screened for the original publications. Articles that we missed were published in non-English languages, published before 1975, published very recently, or available only as conference abstracts. In the second study, we retrieved 79% of included studies while screening half the original number of articles. Citation searching appears to be an efficient and reasonably accurate method for finding articles similar to one or more articles of interest for meta-analysis and reviews.

Citation analyses are currently influencing individual career advancement and ranking of academic and research institutions worldwide. This article overviews the involvement of scientific authors, reviewers, editors, publishers, indexers, and learned associations in the citing and referencing to preserve the integrity of science communication. Authors are responsible for thorough bibliographic searches to select relevant references for their articles, comprehend main points, and cite them in an ethical way. Reviewers and editors may perform additional searches and recommend missing essential references. Publishers, in turn, are in a position to instruct their authors over the citations and references, provide tools for validation of references, and open access to bibliographies. Publicly available reference lists bear important information about the novelty and relatedness of the scholarly items with the published literature. Few editorial associations have dealt with the issue of citations and properly managed references. As a prime example, the International Committee of Medical Journal Editors (ICMJE) issued in December 2014 an updated set of recommendations on the need for citing primary literature and avoiding unethical references, which are applicable to the global scientific community. With the exponential growth of literature and related references, it is critically important to define functions of all stakeholders of science communication in curbing the issue of irrational and unethical citations and thereby improve the quality and indexability of scholarly journals.

    The paper is written with the assumption that the purpose of a mathematical theory of citation is to explain bibliometric regularities at the level of mathematical formalism. A mathematical formalism is proposed for the appearance of power law distributions in social citation systems. The principal contributions of this paper are an axiomatic characterization of citation distributions in terms of the Ekeland variational principle and a mathematical exploration of the power law nature of citation distributions. Apart from its inherent value in providing a better understanding of the mathematical underpinnings of bibliometric models, such an approach can be used to derive a citation distribution from first principles.

    Ageing is accompanied by an increased risk of disease and a loss of functioning on several bodily and mental domains and some argue that maintaining health and functioning is essential for a successful old age. Paradoxically, studies have shown that overall wellbeing follows a curvilinear pattern with the lowest point at middle age but increases thereafter up to very old age. To shed further light on this paradox, we reviewed the existing literature on how scholars define successful ageing and how they weigh the contribution of health and functioning to define success. We performed a novel, hypothesis-free and quantitative analysis of citation networks exploring the literature on successful ageing that exists in the Web of Science Core Collection Database using the CitNetExplorer software. Outcomes were visualized using timeline-based citation patterns. The clusters and sub-clusters of citation networks identified were starting points for in-depth qualitative analysis. Within the literature from 1902 through 2015, two distinct citation networks were identified. The first cluster had 1146 publications and 3946 citation links. It focused on successful ageing from the perspective of older persons themselves. Analysis of the various sub-clusters emphasized the importance of coping strategies, psycho-social engagement, and cultural differences. The second cluster had 609 publications and 1682 citation links and viewed successful ageing based on the objective measurements as determined by researchers. Subsequent sub-clustering analysis pointed to different domains of functioning and various ways of assessment. In the current literature two mutually exclusive concepts of successful ageing are circulating that depend on whether the individual himself or an outsider judges the situation. These different points of view help to explain the disability paradox, as successful ageing lies in the eyes of the beholder. Copyright © 2016 The Authors. Published by Elsevier Ireland

    Full Text Available Social work is a complex and multidisciplinary field drawing on a wide range of literature in terms of format, age, and discipline. Librarians in both collections and public services must be aware of this diversity in order to serve this rapidly growing field. This study was designed to identify core journals in the social work field, the most commonly cited formats and the age of citations, to assess the use of non-social work journals in the social work literature, and to draw comparisons to results in allied health and social science disciplines. The ultimate goal of this work is to provide librarians supporting social work programs with data which can contribute to their assessment of collections, both for maintenance and accreditation, and which can allow them to have a broader understanding of the field and a more effective approach to instruction. 28,269 citations from 567 source articles were examined. Journal articles were the most commonly cited format (69.90%, followed by books (17.69%. Over 91% of all citations came from materials published after 1990 and over 50% of citations came from materials published in the last ten years. Of the 2,520 journals cited, 32 top journals (1.27% accounted for 6,612 (33.46% of all citations to journals. Of those 32 journals, six were assigned to the field of social work. The remaining core journals came from the fields of psychology, public health, psychiatry, family and gender studies, pediatrics, and medicine. Format distribution and citation age were found to be similar to that of psychology, health care management, health education, and nurse practitioners. There was little similarity with the fields of addictions treatment and sociology. Practical implications for librarians are discussed.

    Impact factors are currently the bibliometric index most used for evaluating scientific journals. However, the way in which they are used, for instance concerning the study or journal types analyzed, can markedly interfere with estimate reliability. This study aimed to analyze the citation distribution pattern in three Brazilian journals of general medicine. This was a descriptive study based on numbers of citations of scientific studies published by three Brazilian journals of general medicine. The journals analyzed were São Paulo Medical Journal, Clinics and Revista da Associação Médica Brasileira. This survey used data available from the Institute for Scientific Information (ISI) platform, from which the total number of papers published in each journal in 2007-2008 and the number of citations of these papers in 2009 were obtained. From these data, the citation distribution was derived and journal impact factors (average number of citations) were estimated. These factors were then compared with those directly available from the ISI Journal of Citation Reports (JCR). Respectively, 134, 203 and 192 papers were published by these journals during the period analyzed. The observed citation distributions were highly skewed, such that many papers had few citations and a small percentage had many citations. It was not possible to identify any specific pattern for the most cited papers or to exactly reproduce the JCR impact factors. Use of measures like "impact factors", which characterize citations through averages, does not adequately represent the citation distribution in the journals analyzed.

    Full Text Available Building a complete free and open source GIS computing and data publication platform can be a relatively easy task. This paper describes an automated deployment of such platform using two open source software projects – GIS.lab and Gisquick. GIS.lab (http: //web.gislab.io is a project for rapid deployment of a complete, centrally managed and horizontally scalable GIS infrastructure in the local area network, data center or cloud. It provides a comprehensive set of free geospatial software seamlessly integrated into one, easy-to-use system. A platform for GIS computing (in our case demonstrated on hydrological data processing requires core components as a geoprocessing server, map server, and a computation engine as eg. GRASS GIS, SAGA, or other similar GIS software. All these components can be rapidly, and automatically deployed by GIS.lab platform. In our demonstrated solution PyWPS is used for serving WPS processes built on the top of GRASS GIS computation platform. GIS.lab can be easily extended by other components running in Docker containers. This approach is shown on Gisquick seamless integration. Gisquick (http://gisquick.org is an open source platform for publishing geospatial data in the sense of rapid sharing of QGIS projects on the web. The platform consists of QGIS plugin, Django-based server application, QGIS server, and web/mobile clients. In this paper is shown how to easily deploy complete open source GIS infrastructure allowing all required operations as data preparation on desktop, data sharing, and geospatial computation as the service. It also includes data publication in the sense of OGC Web Services and importantly also as interactive web mapping applications.

    In the past two decades enormously scientific researches on posttraumatic stress disorder (PTSD) have been undertaken and many related meta-analyses have been published. Citation analysis was used to get comprehensive perspectives of meta-analysis articles (MA articles) on PTSD for the purpose of facilitating the researchers, physicians and policy-makers to understand the PTSD. MA articles on PTSD in any languages from January 1980 to March 2009 were included if they presented meta-analytical methods and received at least one citation recorded in the Web of Science (WoS). Whereas studies, in which any effect sizes of PTSD were not distinguished from other psychological disorders, were excluded. Citations to and by identified MA articles were documented basing on records in WoS. Citation analysis was used to examine distribution patterns of characteristics and citation impact of MA articles on PTSD. Canonical analysis was used to explore the relationship between the characteristics of MA articles and citation impact. Thirty-four MA articles published during 1998 and 2008 were identified and revealed multiple study topics on PTSD: 10 (29.4%) were about epidemiology, 13 (38.2%) about treatment or intervention, 6 (17.6%) about pathophysiology or neurophysiology or neuroendocrine, 3 (8.8%) about childhood and 2 (5.9%) about psychosocial adversity. Two articles cited most frequently with 456 and 145 counts were published in Journal of Consulting and Clinical Psychology by Brewin (2000) and Psychological Bulletin by Ozer (2003), respectively. Mean cited count was 7.48 ± 10.56 and mean age (year 2009 minus article publication year) was (4.24 ± 2.91) years. They had been cited approximately by 67 disciplines and by authors from 42 countries or territories. Characteristics of meta-analysis highly correlated with citation impact and reflected by canonical correlation of 0.899 (P < 0.000 01). The age of MA articles predicted their citation impact.

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

  12. Narrative Style Influences Citation Frequency in Climate Change Science.

    Full Text Available Peer-reviewed publications focusing on climate change are growing exponentially with the consequence that the uptake and influence of individual papers varies greatly. Here, we derive metrics of narrativity from psychology and literary theory, and use these metrics to test the hypothesis that more narrative climate change writing is more likely to be influential, using citation frequency as a proxy for influence. From a sample of 732 scientific abstracts drawn from the climate change literature, we find that articles with more narrative abstracts are cited more often. This effect is closely associated with journal identity: higher-impact journals tend to feature more narrative articles, and these articles tend to be cited more often. These results suggest that writing in a more narrative style increases the uptake and influence of articles in climate literature, and perhaps in scientific literature more broadly.

This effect is closely associated with journal identity: higher-impact journals tend to feature more narrative articles, and these articles tend to be cited more often. These results suggest that writing in a more narrative style increases the uptake and influence of articles in climate literature, and perhaps in scientific literature more broadly.

    Full Text Available The journal is fundamental to formal scholarly communication. This research reports highlights and preliminary findings from an empirical study of scholarly electronic journals. The purpose of the research is to assess the impact of electronic journals (e-journals on scholarly communication, by measuring the extent to which they are being cited in the literature, both print and electronic. The intent is to provide a snapshot of the impact e-journals were having on scholarly communication at a given point in time, roughly the end of 1995. This study provides one measure of that impact, specifically on the formal, as opposed to informal, communication process. The study also examines the forms in which scholars cite e-journals, the accuracy and completeness of citations to e-journals, and practical difficulties faced by scholars and researchers who wish to retrieve e-journals through the networks.

    Full Text Available Bibliographic citation is playing an important role today to ensure the completeness of all research activities. They occupy an integral part as a reference in all types of resources need. The author while writing a paper takes the references from a number of documents and finally quotes them with its bibliographic details to recognize the work of earlier authors in the same field of study. With the virtually exponential growth in the research literatures throughout the 20th century it has become clear that the larger the literature the more difficult are the problems caused by poorly crafted bibliographic references. Scholarly societies like publishers of research journals have either produced their own or have endorsed common bibliographic style manuals or standards. In this study we have studied several style manuals and standards for bibliographic referencing and several editorial guidelines for this purpose to compare them. Indian bibliographic standard gets special attention.

    The era of Open Access (OA) publication, a platform which serves to better disseminate scientific knowledge, is upon us, as more OA journals are in existence than ever before. The idea that peer-reviewed OA publication leads to higher rates of citation has been put forth and shown to be true in several publications. This is a significant benefit to authors and is in addition to another relatively less obvious but highly critical component of the OA charter, i.e. retention of the copyright by the authors in the public domain. In this study, we analyzed the citation rates of OA and traditional non-OA publications specifically for authors in the field of cytopathology. We compared the citation patterns for authors who had published in both OA and traditional non-OA peer-reviewed, scientific, cytopathology journals. Citations in an OA publication (CytoJournal) were analyzed comparatively with traditional non-OA cytopathology journals (Acta Cytologica, Cancer Cytopathology, Cytopathology, and Diagnostic Cytopathology) using the data from web of science citation analysis site (based on which the impact factors (IF) are calculated). After comparing citations per publication, as well as a time adjusted citation quotient (which takes into account the time since publication), we also analyzed the statistics after excluding the data for meeting abstracts. Total 28 authors published 314 publications as articles and meeting abstracts (25 authors after excluding the abstracts). The rate of citation and time adjusted citation quotient were higher for OA in the group where abstracts were included (P citation than the publications in the traditional non-OA journals in the field of cytopathology over a 5 year period (2007-2011). However, this increase was statistically insignificant if the meeting abstracts were excluded from the analysis. Overall, the rates of citation for OA and non-OA were slightly higher to comparable.

    The objective of this study was to assess the distribution of citations received by scientific papers published in the imaging literature between 2001 and 2010. We extracted the number of citations of all articles and reviews for 5 years after publication using the Scopus (Elsevier) citation database of imaging journals between 2001 and 2010. We quantitatively analyzed article and review citations from each journal and each year, including the number, proportion, and annual number of citations of the most- (≥ 20 citations) and least-cited (three or fewer citations) papers; ratio of most-cited to least-cited papers; 75/25 percentile citation ratio; 90/10 percentile citation ratio; Gini coefficient; and Kolkata index. Our analysis of 124,331 articles and 13,575 reviews from 121 journals showed that the proportion of most-cited articles (from 19.6% to 27.1%) and reviews (from 19.1% to 37.2%) increased from 2001 to 2010, whereas the proportion of least-cited articles (from 32.3% to 23.0%) and reviews (from 31.9% to 15.8%) declined over the same period. The annual numbers of citations of most-cited articles and reviews both reached a peak in the fourth year after publication, whereas those of least-cited articles and reviews reached a peak in the second and fist years, respectively, after publication and thereafter decreased. The 75/25 percentile ratio for articles declined from 41.1 to 27.5 between 2001 and 2010. Over the same time, the 75/25 percentile ratio for reviews declined from 47.4 to 22.9. The 90/10 percentile ratio for articles declined from 1730.8 to 188.7; for reviews, the 90/10 percentile ratio declined from 5788.0 to 100.7. The Gini coefficient of articles and reviews also declined from 0.6116 to 0.5721 for articles and from 0.6507 to 0.5649 for reviews; the k index, from 0.7260 to 0.7088 for articles from 0.7409 to 0.7072 for reviews. Inequality and polarization of citations consistently decreased in the imaging literature from 2001 to 2010.

    In the last decade, the main Brazilian research funding agencies, CNPq and CAPES, have introduced gender projects aimed to understand the situation of women in general and in science in particular. These projects have led to an increased awareness of the problem. There is still a long way to go in the quest for equal access to opportunities and resources. This paper compares the production and quality of work of female scientists with their male colleagues in the physics and astronomy grant-funded research community in Brazil.

    Scopus and Web of Science are the two major citation databases that collect and disseminate bibliometric statistics about research articles, journals, institutions, and individual authors. Liaison librarians are now regularly called upon to utilize these databases to assist faculty in finding citation activity on their published works for tenure and promotion, grant applications, and more. But questions about the accuracy, scope, and coverage of these tools deserve closer scrutiny. Discrepancies in citation capture led to a systematic study on how Scopus and Web of Science compared in a real-life situation encountered by liaisons: comparing three different disciplines at a medical school and nursing program. How many articles would each database retrieve for each faculty member using the author-searching tools provided? How many cited references for each faculty member would each tool generate? Results demonstrated troubling differences in publication and citation activity capture between Scopus and Web of Science. Implications for librarians are discussed.

InCites offers a unique opportunity to study the normalized citation impacts of countries using (i a long publication window (1981 to 2010, (ii a differentiation in (broad or more narrow subject areas, and (iii allowing for the use of statistical procedures in order to obtain an insightful investigation of national citation trends across the years. Using four broad categories, our results show significantly increasing trends in citation impact values for France, the UK, and especially Germany across the last thirty years in all areas. The citation impact of papers from China is still at a relatively low level (mostly below the world average, but the country follows an increasing trend line. The USA exhibits a stable pattern of high citation impact values across the years. With small impact differences between the publication years, the US trend is increasing in engineering and technology but decreasing in medical and health sciences as well as in agricultural sciences. Similar to the USA, Japan follows increasing as well as decreasing trends in different subject areas, but the variability across the years is small. In most of the years, papers from Japan perform below or approximately at the world average in each subject area.

  3. Link Label Prediction in Signed Citation Network

    KAUST Repository

    2016-04-12

    Link label prediction is the problem of predicting the missing labels or signs of all the unlabeled edges in a network. For signed networks, these labels can either be positive or negative. In recent years, different algorithms have been proposed such as using regression, trust propagation and matrix factorization. These approaches have tried to solve the problem of link label prediction by using ideas from social theories, where most of them predict a single missing label given that labels of other edges are known. However, in most real-world social graphs, the number of labeled edges is usually less than that of unlabeled edges. Therefore, predicting a single edge label at a time would require multiple runs and is more computationally demanding. In this thesis, we look at link label prediction problem on a signed citation network with missing edge labels. Our citation network consists of papers from three major machine learning and data mining conferences together with their references, and edges showing the relationship between them. An edge in our network is labeled either positive (dataset relevant) if the reference is based on the dataset used in the paper or negative otherwise. We present three approaches to predict the missing labels. The first approach converts the label prediction problem into a standard classification problem. We then, generate a set of features for each edge and then adopt Support Vector Machines in solving the classification problem. For the second approach, we formalize the graph such that the edges are represented as nodes with links showing similarities between them. We then adopt a label propagation method to propagate the labels on known nodes to those with unknown labels. In the third approach, we adopt a PageRank approach where we rank the nodes according to the number of incoming positive and negative edges, after which we set a threshold. Based on the ranks, we can infer an edge would be positive if it goes a node above the

  4. A generalized view of self-citation: direct, co-author, collaborative, and coercive induced self-citation.

    The phenomenon of self-citation can present in many different forms, including direct, co-author, collaborative, and coercive induced self-citation. It can also pertain to the citation of single scientists, groups of scientists, journals, and institutions. This article presents some case studies of extreme self-citation practices. It also discusses the implications of different types of self-citation. Self-citation is not necessarily inappropriate by default. In fact, usually it is fully appropriate but often it is even necessary. Conversely, inappropriate self-citation practices may be highly misleading and may distort the scientific literature. Coercive induced self-citation is the most difficult to discover. Coercive Induced self-citation may happen directly from reviewers of articles, but also indirectly from reviewers of grants, scientific advisors who steer a research agenda, and leaders of funding agencies who may espouse spending disproportionately large funds in research domains that perpetuate their own self-legacy. Inappropriate self-citation can be only a surrogate marker of what might be much greater distortions of the scientific corpus towards conformity to specific opinions and biases. Inappropriate self-citations eventually affect also impact metrics. Different impact metrics vary in the extent to which they can be gamed through self-citation practices. Citation indices that are more gaming-proof are available and should be more widely used. We need more empirical studies to dissect the impact of different types of inappropriate self-citation and to examine the effectiveness of interventions to limit them. Copyright © 2014.

    Citation metrics and total publications in a field has become the gold standard for rating researchers and viability of a field. Hence, stimulating demand for citation has led to a search for useful strategies to improve performance metric index. Meanwhile, title, abstract and morphologic qualities of the articles attract researchers to scientific publications. Yet, there is relatively little understanding of the citation trend in disability related fields. We aimed to provide an insight into the factors associated with citation increase in this field. Additionally, we tried to know at what page number an article might appear attractive to disability researchers needs. Thus, our focus is placed on the article page count and the number of authors contributing to the fields per article. To this end, we evaluated the quantitative characteristics of top cited articles in the fields with a total citation (≥50) in the Web of Science (WoS) database. Using one-way independent ANOVA, data extracted spanning a period of 1980-2015 were analyzed, while the non-parametric data analysis uses Kruskal-Walis test. Articles with 11 to 20 pages attract more citations followed by those within the range of zero to 10. Articles with upward 21 pages are the least cited. Surprisingly, articles with more than two authors are significantly ( P <0.05) less cited and the citation decreases as the number of authors increased. Collaborative studies enjoy wider utilization and more citation, yet discounted merit of additional pages and limited collaborative research in disability field is revealed in this study.

    Molecular biology and literature databases represent essential infrastructure for life science research. Effective integration of these data resources requires that there are structured cross-references at the level of individual articles and biological records. Here, we describe the current patterns of how database entries are cited in research articles, based on analysis of the full text Open Access articles available from Europe PMC. Focusing on citation of entries in the European Nucleotide Archive (ENA), UniProt and Protein Data Bank, Europe (PDBe), we demonstrate that text mining doubles the number of structured annotations of database record citations supplied in journal articles by publishers. Many thousands of new literature-database relationships are found by text mining, since these relationships are also not present in the set of articles cited by database records. We recommend that structured annotation of database records in articles is extended to other databases, such as ArrayExpress and Pfam, entries from which are also cited widely in the literature. The very high precision and high-throughput of this text-mining pipeline makes this activity possible both accurately and at low cost, which will allow the development of new integrated data services.

Five andrology journals indexed by Science Citation Index Expanded (SCI-E) (Andrologia, Archives of Andrology, Asian Journal of Andrology, International Journal of Andrology, and Journal of Andrology) were included in the study. Original articles, editorials, reviews, corrections and letters from these journals were analyzed with bibliometric method for document loading, citations, information absorbing ability, and geographical coverage. The average number of references in each paper was 28.78. The main type of references was periodicals (94.32%), while books and other sources accounted for only 5.68%. Average Price index was 30.14%. The number of references in the first ranking 10 periodicals cited by the five journals made up 34.53% of the total references cited. Geographically, the five journals covered 6 continents with 42 countries or regions. Andrology journals have a wide coverage of literatures, which are related to reproductive medicine, urology, endocrinology and biochemistry. References in andrology journals are mainly periodicals and are relatively old. US, China and Japan lead the world in andrology researches for the number of papers published.

    Do you write code for your research? Use astronomical software? Do you wish there were a better way of citing, sharing, archiving, or discovering software for astronomy research? You're not alone! In April 2015, AAS's publishing team joined other leaders in the astronomical software community in a meeting funded by the Sloan Foundation, with the purpose of discussing these issues and potential solutions. In attendance were representatives from academic astronomy, publishing, libraries, for-profit software sharing platforms, telescope facilities, and grantmaking institutions. The goal of the group was to establish “protocols, policies, and platforms for astronomical software citation, sharing, and archiving,” in the hopes of encouraging a set of normalized standards across the field. The AAS is now collaborating with leaders at GitHub to write grant proposals for a project to develop strategies for software discoverability and citation, in astronomy and beyond. If this topic interests you, you can find more details in this document released by the group after the meeting: http://astronomy-software-index.github.io/2015-workshop/ The group hopes to move this project forward with input and support from the broader community.

  11. Data Citation Standard: A Means to Support Data Sharing, Attribution, and Traceability

    Geo-referenced data are crucial for addressing many of the burning societal problems and to support related interdisciplinary research. Data sharing is hampered by the lack of a widely accepted method for giving credit to those who make their data freely available and for tracking the use of data throughout it's life-cycle. Particularly in the scientific community, recognition and renown are important currencies. Providing means for data citation would be a strong incentive for data sharing. Recently, a number of organizations and projects have started to address the concept of data citation (e.g., PANGAEA, NASA DAACS, USGS, NOAA National Data Centers, ESIP, US National Academy of Sciences, and EGIDA). A number of proposals for data citation guidelines have emerged and a better understanding of the many issues at hand is evolving, but to date, no standard has been accepted. This is not surprising, as data citation is far more complicated than citation of scientific publication. Data sets differ in many aspects from standard scientific publications. For example, data sets generally are not locatable and attributable in the same way as scientific publications. Data sets often are not static (introducing versioning), and they are mostly not peer-reviewed (requiring quality control). There is a consensus that the implementation of a standard would reveal new issues that are not obvious today. With the Global Earth Observation System of Systems (GEOSS), the Group on Earth Observations (GEO) is in a unique position to provide the testbed for the implementation of a draft standard. The GEO Plenary supports the implementation of a draft standard developed by the Science and Technology Committee (STC) of GEO with support of the EGIDA Project. This draft is based on guidelines developed by international groups. Currently, users of the GEO-Portal are not obliged or encouraged to cite data accessed through GEOSS - if at all, citation requirements come from the individual data

    Full Text Available Aim: Informal citations is bibliographic information (title or Internet address, citing sources of information resources for informal scholarly communication and always neglected in traditional citation databases. This study is done, in order to answer the question of whether informal citations in the web environment are traceable. The present research aims to determine what proportion of web citations of Google search engine is related to formal and informal citation. Research method: Webometrics is the method used. The study is done on 1344 research articles of 98 open access journal, and the method that is used to extract the web citation from Google search engine is “Web / URL citation extraction". Findings: The findings showed that ten percent of the web citations of Google search engine are formal and informal citations. The highest formal citation in the Google search engine with 19/27% is in the field of library and information science and the lowest official citation by 1/54% is devoted to the field of civil engineering. The highest percentage of informal citations with 3/57% is devoted to sociology and the lowest percentage of informal citations by 0/39% is devoted to the field of civil engineering. Journal Citation is highest with 94/12% in the surgical field and lowest with 5/26 percent in the philosophy filed. Result: Due to formal and informal citations in the Google search engine which is about 10 percent and the reduction of this amount compared to previous research, it seems that track citations by this engine should be treated with more caution. We see that the amount of formal citation is variable in different disciplines. Cited journals in the field of surgery, is highest and in the filed of philosophy is lowest, this indicates that in the filed of philosophy, that is a subset of the social sciences, journals in scientific communication do not play a significant role. On the other hand, book has a key role in this filed

    Publication statistics are ubiquitous in the ratings of scientific achievement, with citation counts and paper tallies factoring into an individual’s consideration for postdoctoral positions, junior faculty, and tenure. Citation statistics are designed to quantify individual career achievement, both at the level of a single publication, and over an individual’s entire career. While some academic careers are defined by a few significant papers (possibly out of many), other academic careers are defined by the cumulative contribution made by the author’s publications to the body of science. Several metrics have been formulated to quantify an individual’s publication career, yet none of these metrics account for the collaboration group size, and the time dependence of citation counts. In this paper we normalize publication metrics in order to achieve a universal framework for analyzing and comparing scientific achievement across both time and discipline. We study the publication careers of individual authors over the 50-year period 1958-2008 within six high-impact journals: CELL, the New England Journal of Medicine (NEJM), Nature, the Proceedings of the National Academy of Science (PNAS), Physical Review Letters (PRL), and Science. Using the normalized metrics (i) “citation shares” to quantify scientific success, and (ii) “paper shares” to quantify scientific productivity, we compare the career achievement of individual authors within each journal, where each journal represents a local arena for competition. We uncover quantifiable statistical regularity in the probability density function of scientific achievement in all journals analyzed, which suggests that a fundamental driving force underlying scientific achievement is the competitive nature of scientific advancement.

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

    Of the existing theoretical formulas for the h -index, those recently suggested by Burrell (J Informetr 7:774-783, 2013b) and by Bertoli-Barsotti and Lando (J Informetr 9(4):762-776, 2015) have proved very effective in estimating the actual value of the h -index Hirsch (Proc Natl Acad Sci USA 102:16569-16572, 2005), at least at the level of the individual scientist. These approaches lead (or may lead) to two slightly different formulas, being based, respectively, on a "standard" and a "shifted" version of the geometric distribution. In this paper, we review the genesis of these two formulas-which we shall call the "basic" and "improved" Lambert- W formula for the h -index-and compare their effectiveness with that of a number of instances taken from the well-known Glänzel-Schubert class of models for the h -index (based, instead, on a Paretian model) by means of an empirical study. All the formulas considered in the comparison are "ready-to-use", i.e., functions of simple citation indicators such as: the total number of publications; the total number of citations; the total number of cited paper; the number of citations of the most cited paper. The empirical study is based on citation data obtained from two different sets of journals belonging to two different scientific fields: more specifically, 231 journals from the area of "Statistics and Mathematical Methods" and 100 journals from the area of "Economics, Econometrics and Finance", totaling almost 100,000 and 20,000 publications, respectively. The citation data refer to different publication/citation time windows, different types of "citable" documents, and alternative approaches to the analysis of the citation process ("prospective" and "retrospective"). We conclude that, especially in its improved version, the Lambert- W formula for the h -index provides a quite robust and effective ready-to-use rule that should be preferred to other known formulas if one's goal is (simply) to derive a reliable estimate of

    The patent citation networks are described using critical node, core network, and network topological analysis. The main objective is understanding of the knowledge transfer processes between technical fields, institutions and countries. This includes identifying key influential players and subfields, the knowledge transfer patterns among them, and the overall knowledge transfer efficiency. The proposed framework is applied to the field of nanoscale science and engineering (NSE), including the citation networks of patent documents, submitting institutions, technology fields, and countries. The NSE patents were identified by keywords 'full-text' searching of patents at the United States Patent and Trademark Office (USPTO). The analysis shows that the United States is the most important citation center in NSE research. The institution citation network illustrates a more efficient knowledge transfer between institutions than a random network. The country citation network displays a knowledge transfer capability as efficient as a random network. The technology field citation network and the patent document citation network exhibit a less efficient knowledge diffusion capability than a random network. All four citation networks show a tendency to form local citation clusters

    There are some 300 repositories of research material (Source: IAR), most of which have an OAI-PMH interface, but no current Institutional Repositories export reference data - nor do they provide their users with citation impact metrics. We propose a model for extending IR's to be citation aware and to expose that data to citation indices using the OAI-PMH and OpenURL. We present some techniques for the export of citation data using the OAI-PMH in Citebase Search. As part of a proposed Open Access Citation Information study we have developed a proposal for the integration of reference parsing and linking into the author- deposit process. This highly-distributed approach to citation linking utilises the OAI-PMH to transfer structured citation data between IRs and citation indexing services.

    Bornmann, Lutz; Ye, Adam Y; Ye, Fred Y

    2017-01-01

    In bibliometrics, only a few publications have focused on the citation histories of publications, where the citations for each citing year are assessed. In this study, therefore, annual categories of field- and time-normalized citation scores (based on the characteristic scores and scales method: 0 = poorly cited, 1 = fairly cited, 2 = remarkably cited, and 3 = outstandingly cited) are used to study the citation histories of papers. As our dataset, we used all articles published in 2000 and their annual citation scores until 2015. We generated annual sequences of citation scores (e.g., [Formula: see text]) and compared the sequences of annual citation scores of six broader fields (natural sciences, engineering and technology, medical and health sciences, agricultural sciences, social sciences, and humanities). In agreement with previous studies, our results demonstrate that sequences with poorly cited (0) and fairly cited (1) elements dominate the publication set; sequences with remarkably cited (3) and outstandingly cited (4) periods are rare. The highest percentages of constantly poorly cited papers can be found in the social sciences; the lowest percentages are in the agricultural sciences and humanities. The largest group of papers with remarkably cited (3) and/or outstandingly cited (4) periods shows an increasing impact over the citing years with the following orders of sequences: [Formula: see text] (6.01%), which is followed by [Formula: see text] (1.62%). Only 0.11% of the papers ( n  = 909) are constantly on the outstandingly cited level.

    Full Text Available Objective – To investigate the citation performance of open access (OA and toll access (TA papers published in author-pays open access journals. Design – Longitudinal citation analysis. Setting – Publications in Springer and Elsevier’s author-pays open access journals. Subjects – 633 journals published using the author-pays model. This model encompasses both journals where the article processing charge (APC is required and journals in which authors can request open access and voluntarily pay APCs for accepted manuscripts. Methods – The authors identified APC funded journals (journals funded by mandatory author processing charges as well as those where authors voluntarily paid a fee in order to have their articles openly accessible from both Springer and Elsevier, and analyzed papers published in these journals from 2007 to 2011. The authors excluded journals that adopted the APC model later than 2007. To identify Springer titles, the authors created a search strategy to identify open access articles in SpringerLink. A total of 576 journals were identified and double checked in the Sherpa-Romeo database (a database of copyright and open access self-archiving policies of academic journals to verify their open access policies. The authors then downloaded the journal content using SpringerLink, and using Springer Author-Mapper, separated out the open access articles from the toll access articles. In order to identify the Elsevier APC funded journals, the authors referred to “Open Access Journal Directory: A-Z,” which contained 35 OA journals (p. 584. Once the authors consulted “Sponsored articles” issued by Elsevier and verified titles in Sherpa-Romeo, they identified 57 journals that fit the “author-pays” model. The bibliographic information was downloaded and OA articles were separated from TA articles. The authors confirmed that all journals were indeed OA publications by downloading the full-text from off-campus locations

    We conducted a citation analysis to explore the impact of articles published in Health Psychology and determine whether the journal is fulfilling its stated mission. Six years of articles (N = 408) representing three editorial tenures from 1993-2003 were selected for analysis. Articles were coded for several dimensions enabling examination of the relationship of article features to subsequent citations rates. Journals citing articles published in Health Psychology were classified into four categories: (1) psychology, (2) medicine, (3) public health and health policy, and (4) other journals. The majority of citations of Health Psychology articles were in psychology journals, followed closely by medical journals. Studies reporting data collected from college students, and discussing the theoretical implications of findings, were more likely to be cited in psychology journals, whereas studies reporting data from clinical populations, and discussing the practice implications of findings, were more likely to be cited in medical journals. Time since publication and page length were both associated with increased citation counts, and review articles were cited more frequently than observational studies. Articles published in Health Psychology have a wide reach, informing psychology, medicine, public health and health policy. Certain characteristics of articles affect their subsequent pattern of citation. (PsycINFO Database Record (c) 2010 APA, all rights reserved).

    In the scientific research community, plagiarism and covert multiple publications of the same data are considered unacceptable because they undermine the public confidence in the scientific integrity. Yet, little has been done to help authors and editors to identify highly similar citations, which sometimes may represent cases of unethical duplication. For this reason, we have made available Déjà vu, a publicly available database of highly similar Medline citations identified by the text similarity search engine eTBLAST. Following manual verification, highly similar citation pairs are classified into various categories ranging from duplicates with different authors to sanctioned duplicates. Déjà vu records also contain user-provided commentary and supporting information to substantiate each document's categorization. Déjà vu and eTBLAST are available to authors, editors, reviewers, ethicists and sociologists to study, intercept, annotate and deter questionable publication practices. These tools are part of a sustained effort to enhance the quality of Medline as 'the' biomedical corpus. The Déjà vu database is freely accessible at http://spore.swmed.edu/dejavu. The tool eTBLAST is also freely available at http://etblast.org.

    Full Text Available Abstract Background Understanding research activity within any given biomedical field is important. Search outputs generated by MEDLINE/PubMed are not well classified and require lengthy manual citation analysis. Automation of citation analytics can be very useful and timesaving for both novices and experts. Results PubFocus web server automates analysis of MEDLINE/PubMed search queries by enriching them with two widely used human factor-based bibliometric indicators of publication quality: journal impact factor and volume of forward references. In addition to providing basic volumetric statistics, PubFocus also prioritizes citations and evaluates authors' impact on the field of search. PubFocus also analyses presence and occurrence of biomedical key terms within citations by utilizing controlled vocabularies. Conclusion We have developed citations' prioritisation algorithm based on journal impact factor, forward referencing volume, referencing dynamics, and author's contribution level. It can be applied either to the primary set of PubMed search results or to the subsets of these results identified through key terms from controlled biomedical vocabularies and ontologies. NCI (National Cancer Institute thesaurus and MGD (Mouse Genome Database mammalian gene orthology have been implemented for key terms analytics. PubFocus provides a scalable platform for the integration of multiple available ontology databases. PubFocus analytics can be adapted for input sources of biomedical citations other than PubMed.

  6. Bibliography for transportation energy conservation. [578 citations

    1976-05-01

    A listing is given of 578 reports, books, articles, and conference papers on transportation and energy. Coverage is primarily on U. S. developments and research from 1970 to 1975. Following a section of citations of general works on energy, the bibliography contains two main parts: ''Energy for Transportation'' and ''Transportation of Energy.'' Within each of these topics the arrangement is multimodal (at the urban, regional, national, or international level), then by mode. Selected information sources are listed in the last part. Within each section, entries are arranged alphabetically by author or, lacking an author, by title. References were drawn from the Transportation Center Library collection and other libraries in the Northwestern University system. An earlier bibliography, Transportation and Energy, compiled by the Transportation Center Library in March 1974, forms the basis for the arrangement and provides coverage from 1970 to 1973.

    2015-12-01

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

    Luiggi Araujo Lustosa

    Full Text Available CONTEXT AND OBJECTIVE: Impact factors are currently the bibliometric index most used for evaluating scientific journals. However, the way in which they are used, for instance concerning the study or journal types analyzed, can markedly interfere with estimate reliability. This study aimed to analyze the citation distribution pattern in three Brazilian journals of general medicine. DESIGN AND SETTING: This was a descriptive study based on numbers of citations of scientific studies published by three Brazilian journals of general medicine. METHODS: The journals analyzed were São Paulo Medical Journal, Clinics and Revista da Associação Médica Brasileira. This survey used data available from the Institute for Scientific Information (ISI platform, from which the total number of papers published in each journal in 2007-2008 and the number of citations of these papers in 2009 were obtained. From these data, the citation distribution was derived and journal impact factors (average number of citations were estimated. These factors were then compared with those directly available from the ISI Journal of Citation Reports (JCR. RESULTS: Respectively, 134, 203 and 192 papers were published by these journals during the period analyzed. The observed citation distributions were highly skewed, such that many papers had few citations and a small percentage had many citations. It was not possible to identify any specific pattern for the most cited papers or to exactly reproduce the JCR impact factors. CONCLUSION: Use of measures like "impact factors", which characterize citations through averages, does not adequately represent the citation distribution in the journals analyzed.

    To investigate the current prevalence of open access (OA) in the field of dentistry, the means used to provide OA, as well as the association between OA and citation counts. PubMed was searched for dental articles published in 2013. The OA status of each article was determined by manually checking Google, Google Scholar, PubMed and ResearchGate. Citation data were extracted from Google Scholar, Scopus and Web of Science. Chi-square tests were used to compare the OA prevalence by different subjects, study types, and continents of origin. The association between OA and citation count was studied with multivariable logistic regression analyses. A random sample of 908 articles was deemed eligible and therefore included. Among these, 416 were found freely available online, indicating an overall OA rate of 45.8%. Significant difference in OA rate was detected among articles in different subjects (Pdentistry, 54% of recent journal articles are behind the paywall (non-OA) one year after their publication dates. The 'Green road' of providing OA was more common than the 'Gold road'. No evidence suggested that OA articles received significantly more citations than non-OA articles.

    2015-01-01

    In this study, we present an analysis of data citation practices in full text research articles and their corresponding supplementary data files, made available in the Open Access set of articles from Europe PubMed Central. Our aim is to investigate whether supplementary data files should be considered as a source of information for integrating the literature with biomolecular databases. Using text-mining methods to identify and extract a variety of core biological database accession numbers, we found that the supplemental data files contain many more database citations than the body of the article, and that those citations often take the form of a relatively small number of articles citing large collections of accession numbers in text-based files. Moreover, citation of value-added databases derived from submission databases (such as Pfam, UniProt or Ensembl) is common, demonstrating the reuse of these resources as datasets in themselves. All the database accession numbers extracted from the supplementary data are publicly accessible from http://dx.doi.org/10.5281/zenodo.11771. Our study suggests that supplementary data should be considered when linking articles with data, in curation pipelines, and in information retrieval tasks in order to make full use of the entire research article. These observations highlight the need to improve the management of supplemental data in general, in order to make this information more discoverable and useful.

    Research data are fundamental to the success of the academic enterprise, and yet the practice of citing data in academic and applied works is not widespread among researchers. Researchers need credit for their contributions, and yet current citation infrastructure focuses primarily on citations to research literature. Some citation indiexing systems even systematically exclude citations to data from their corpus. The Making Data Count (MDC) project will enable measuring the impact of research data much as is currently being done with publications, the primary vehicle for scholarly credit and accountability. The MDC team (including the California Digital Library, COUNTER, DataCite, and DataONE) are working together to publish a new COUNTER recommendation on data usage statistics; launch a DataCite-hosted MDC service for aggregated DLM based on the open-source Lagotto platform; and build tools for data repository and discovery services to easily integrate with the new MDC service. In providing such data-level metrics (DLM), the MDC project augments existing measures of scholarly success and so offers an important incentive promoting open data principles and quality research data through adoption of research data management best practices.

  12. Texting and accessing the web while driving: traffic citations and crashes among young adult drivers.

    Cook, Jerry L; Jones, Randall M

    2011-12-01

    We examined relations between young adult texting and accessing the web while driving with driving outcomes (viz. crashes and traffic citations). Our premise is that engaging in texting and accessing the web while driving is not only distracting but that these activities represent a pattern of behavior that leads to an increase in unwanted outcomes, such as crashes and citations. College students (N = 274) on 3 campuses (one in California and 2 in Utah) completed an electronic questionnaire regarding their driving experience and cell phone use. Our data indicate that 3 out of 4 (74.3%) young adults engage in texting while driving, over half on a weekly basis (51.8%), and some engage in accessing the web while driving (16.8%). Data analysis revealed a relationship between these cell phone behaviors and traffic citations and crashes. The findings support Jessor and Jessor's (1977) "problem behavior syndrome" by showing that traffic citations are related to texting and accessing the web while driving and that crashes are related to accessing the web while driving. Limitations and recommendations are discussed.

    Staphylococcus aureus is an important cause of bloodstream infections. Therefore, the main purpose of this work was to characterize a collection of 139 S. aureus isolates from bloodstream infections in two public hospitals in relation to their antimicrobial susceptibility profile, staphylococcal cassette chromosome mec types, and clonal relationship. Methicillin resistance and resistance to other 12 agents were accessed by the disk diffusion test. Minimum inhibitory concentration to mupirocin was also determined. The SCCmec types were accessed by multiplex PCR, and the clonal relationship was determined by pulsed field gel electrophoresis method and restriction modification system characterization. Besides, multilocus sequence typing was performed for representative methicillin-resistant S. aureus isolates. The military hospital showed a dissemination of the New York/Japan (USA100/ST5/CC5/SCCmecII) lineage associated to multidrug resistance, including mupirocin resistance, and the teaching hospital presented polyclonal and non-multidrug resistant MRSA isolates. Complete substitution of the Brazilian endemic clone by other lineages was found in both hospitals. These findings can highlight differences in policy control and prevention of infections used in the hospitals and a change in the epidemiological profile of MRSA in Brazilian hospitals, with the replacement of BEC, a previously well-established clone, by other lineages.

    To determine whether algorithms developed for the World Wide Web can be applied to the biomedical literature in order to identify articles that are important as well as relevant. DESIGN AND MEASUREMENTS A direct comparison of eight algorithms: simple PubMed queries, clinical queries (sensitive and specific versions), vector cosine comparison, citation count, journal impact factor, PageRank, and machine learning based on polynomial support vector machines. The objective was to prioritize important articles, defined as being included in a pre-existing bibliography of important literature in surgical oncology. RESULTS Citation-based algorithms were more effective than noncitation-based algorithms at identifying important articles. The most effective strategies were simple citation count and PageRank, which on average identified over six important articles in the first 100 results compared to 0.85 for the best noncitation-based algorithm (p PageRank more than simple citation count. However, in spite of citation lag, citation-based algorithms remain more effective than noncitation-based algorithms. CONCLUSION Algorithms that have proved successful on the World Wide Web can be applied to biomedical information retrieval. Citation-based algorithms can help identify important articles within large sets of relevant results. Further studies are needed to determine whether citation-based algorithms can effectively meet actual user information needs.

  15. Citation Matching in Sanskrit Corpora Using Local Alignment

    Science.gov (United States)

    Prasad, Abhinandan S.; Rao, Shrisha

    Citation matching is the problem of finding which citation occurs in a given textual corpus. Most existing citation matching work is done on scientific literature. The goal of this paper is to present methods for performing citation matching on Sanskrit texts. Exact matching and approximate matching are the two methods for performing citation matching. The exact matching method checks for exact occurrence of the citation with respect to the textual corpus. Approximate matching is a fuzzy string-matching method which computes a similarity score between an individual line of the textual corpus and the citation. The Smith-Waterman-Gotoh algorithm for local alignment, which is generally used in bioinformatics, is used here for calculating the similarity score. This similarity score is a measure of the closeness between the text and the citation. The exact- and approximate-matching methods are evaluated and compared. The methods presented can be easily applied to corpora in other Indic languages like Kannada, Tamil, etc. The approximate-matching method can in particular be used in the compilation of critical editions and plagiarism detection in a literary work.

    Chi, P.S.; Glänzel, W.

    2016-07-01

    In this study usage counts and times cited from Web of Science Core Collection (WoS) were collected for each article published in 2013 with Belgian, Israeli and Iranian addresses. We investigate the relations among three indicators related to citation impact, usage counts coauthorship, respectively. In addition, we apply the method of Characteristic Scores and Scal (CSS) to analyse the distributions of citations and usage counts. The results show that citations and usage counts in WoS correlate to each other significantly, especially in the social sciences. However, the increase of the number of co-authors does not increase usage counts or citations significantly. Furthermore, the stability of CSS-class distributions proves the availability of CSS in characterising both usage and citation distributions. (Author)

While several databases specify how data should be cited, they leave it to users to manually construct the citations and do not generate them automatically. We report our experiences in automating data citation for an RDF dataset called eagle-i, and discuss how to generalize this to a citation framework that can work across a variety of different types of databases (e.g. relational, XML, and RDF). We also describe how a database administrator would use this framework to automate citation for a particular dataset.

  6. The Ripple Effect: Citation Chain Reactions of a Nobel Prize

    This paper explores the possible citation chain reactions of a Nobel Prize using the mathematician Robert J. Aumann as a case example. The results show that the award of the Nobel Prize in 2005 affected not only the citations to his work, but also affected the citations to the references in his s...... citation network. The effect is discussed using innovation decision process theory as a point of departure to identify the factors that created a bandwagon effect leading to the reported observations....... scientific oeuvre. The results indicate that the spillover effect is almost as powerful as the effect itself. We are consequently able to document a ripple effect in which the awarding of the Nobel Prize ignites a citation chain reaction to Aumann's scientific ouvre and to the references in its nearest...

    1989-01-01

    The purpose of this study was to identify objectively a hierarchical ranking of journals for health sciences librarians with faculty status. Such a guideline can indicate a journal's value for promotion and tenure consideration. Lists of recent research articles (1982-1986) in health sciences librarianship, and articles written by health sciences librarians, were compiled by searching Social SCISEARCH and MEDLINE. The journals publishing those articles are presented. Results show BMLA as the most prominent journal in the field. Therefore, citations from articles in BMLA from 1982 to 1986 were chosen as a sample for citation analysis. Citation analysis was employed to identify the most frequently cited journals. Some characteristics of the citations in BMLA are also discussed. The ranking of journals based on citation frequency, as a result, was identified. PMID:2655785

  8. Relative Citation Ratio of Top Twenty Macedonian Biomedical Scientists in PubMed: A New Metric that Uses Citation Rates to Measure Influence at the Article Level.

    Spiroski, Mirko

    2016-06-15

    The aim of this study was to analyze relative citation ratio (RCR) of top twenty Macedonian biomedical scientists with a new metric that uses citation rates to measure influence at the article level. Top twenty Macedonian biomedical scientists were identified by GoPubMed on the base of the number of deposited abstracts in PubMed, corrected with the data from previously published paper, and completed with the Macedonian biomedical scientists working in countries outside the Republic of Macedonia, but born or previously worked in the country. iCite was used as a tool to access a dashboard of bibliometrics for papers associated with a portfolio. The biggest number of top twenty Macedonian biomedical scientists has RCR lower than one. Only four Macedonian biomedical scientists have bigger RCR in comparison with those in PubMed. The most prominent RCR of 2.29 has Rosoklija G. RCR of the most influenced individual papers deposited in PubMed has shown the biggest value for the paper of Efremov D (35.19). This paper has the biggest number of authors (860). It is necessary to accept top twenty Macedonian biomedical scientists as an example of new metric that uses citation rates to measure influence at the article level, rather than qualification of the best Macedonian biomedical scientists.

  9. If I tweet will you cite? The effect of social media exposure of articles on downloads and citations.

    2016-05-01

    We sought to investigate whether exposing scientific papers to social media (SM) has an effect on article downloads and citations. We randomized all International Journal of Public Health (IJPH) original articles published between December 2012 and December 2014 to SM exposure (blog post, Twitter and Facebook) or no exposure at three different time points after first online publication. 130 papers (SM exposure = 65, control = 65) were randomized. The number of downloads did not differ significantly between groups (p = 0.60) nor did the number of citations (p = 0.88). Adjusting for length of observation and paper's geographical origin did not change these results. There was no difference in the number of downloads and citations between the SM exposure and control group when we stratified for open access status. The number of downloads and number of citations were significantly correlated in both groups. SM exposure did not have a significant effect on traditional impact metrics, such as downloads and citations. However, other metrics may measure the added value that social media might offer to a scientific journal, such as wider dissemination.

    Citation data of 16 biochemistry and plant physiology journals show that reasons for lower citation potentials of plant physiology articles are: (1) readership is narrower for plant physiology journals; (2) plant physiologists can cite fewer thematically relevant new articles; and (3) plant physiology research fields are more isolated.

    Full Text Available This article analyzes motivations behind social sciences blog posts citing journal articles in order to find out whether blog citations are good indicators for the societal impact or benefits of research. A random sample of 300 social sciences blog posts (out of 1,233 blog posts from ResearchBlogging.org published between 01/01/2012 to 18/06/2014 were subjected to content analysis. The 300 blog posts had 472 references including 424 journal articles from 269 different journals. Sixty‐one (22.68% of all cited journals were from the social sciences and most of the journals with high frequency were highly cited general science journals such as PNAS and Science. Seventy‐five percent of all journals were referenced only once. The average age of articles cited at the time of citation was 5.8 years. Discussion and criticism were the two main categories of motivations. Overall, the study shows the potential of blog citations as an altmetric measure and as a proxy for assessing the research impact. A considerable number of citation motivations in blogs such as disputing a belief, suggesting policies, providing a solution to a problem, reacting to media, criticism and the like seemed to support gaining societal benefits. Societal benefits are considered as helping stimulate new approaches to social issues, or informing public debate and policymaking. Lower self‐citation (compared to some other altmetric measures such as tweets and the fact that blogging involves generating content (i.e. an intellectual process give them an advantage for altmetrics. However, limitations and contextual issues such as disciplinary differences and low uptake of altmetrics, in general, in scholarly communication should not be ignored when using blogs as a data source for altmetrics.

  12. Multiple Citation Indicators and Their Composite across Scientific Disciplines.

    2016-07-01

    Many fields face an increasing prevalence of multi-authorship, and this poses challenges in assessing citation metrics. Here, we explore multiple citation indicators that address total impact (number of citations, Hirsch H index [H]), co-authorship adjustment (Schreiber Hm index [Hm]), and author order (total citations to papers as single; single or first; or single, first, or last author). We demonstrate the correlation patterns between these indicators across 84,116 scientists (those among the top 30,000 for impact in a single year [2013] in at least one of these indicators) and separately across 12 scientific fields. Correlation patterns vary across these 12 fields. In physics, total citations are highly negatively correlated with indicators of co-authorship adjustment and of author order, while in other sciences the negative correlation is seen only for total citation impact and citations to papers as single author. We propose a composite score that sums standardized values of these six log-transformed indicators. Of the 1,000 top-ranked scientists with the composite score, only 322 are in the top 1,000 based on total citations. Many Nobel laureates and other extremely influential scientists rank among the top-1,000 with the composite indicator, but would rank much lower based on total citations. Conversely, many of the top 1,000 authors on total citations have had no single/first/last-authored cited paper. More Nobel laureates of 2011-2015 are among the top authors when authors are ranked by the composite score than by total citations, H index, or Hm index; 40/47 of these laureates are among the top 30,000 by at least one of the six indicators. We also explore the sensitivity of indicators to self-citation and alphabetic ordering of authors in papers across different scientific fields. Multiple indicators and their composite may give a more comprehensive picture of impact, although no citation indicator, single or composite, can be expected to select all the

  14. Bibliometrics as weapons of mass citation.

    Science.gov (United States)

    Molinié, Antoinette; Bodenhausen, Geoffrey

    2010-01-01

    The allocation of resources for research is increasingly based on so-called 'bibliometrics'. Scientists are now deemed to be successful on the sole condition that their work be abundantly cited. This world-wide trend appears to enjoy support not only by granting agencies (whose task is obviously simplified by extensive recourse to bibliometrics), but also by the scientists themselves (who seem to enjoy their status of celebrities). This trend appears to be fraught with dangers, particularly in the area of social sciences, where bibliometrics are less developed, and where monographs (which are not taken into account in citation indexes) are often more important than articles published in journals. We argue in favour of a return to the values of 'real science', in analogy to the much-promised return to a 'real economy'. While economists may strive towards a more objective evaluation of the prospects of a company, a market, or an industrial sector, we scientists can only base our appraisal on a responsible practice of peer review. Since we fear that decision-takers of granting agencies such as the FNRS, CTI, EPFL, ETHZ, ANR, CNRS, NIH, NSF, DOE, etc. will be too busy to read our humble paper in Chimia, we appeal to scientists of all countries and disciplines to unite against the tyranny of bibliometrics.

  15. Application of progressive nucleation mechanism for the citation behavior of individual papers of different authors.

    Sangwal, Keshra

    2012-09-01

    The basic concepts and equations of the progressive nucleation mechanism (PNM) are presented first for the growth and decay of items. The mechanism is then applied to describe the cumulative citations L and citations ΔL per year of the individual most-cited papers i of four selected Polish professors as a function of citation duration t. It was found that the PNM satisfactorily describes the time dependence of cumulative citations L of the papers published by different authors with sufficiently high citations ΔL, as represented by the highest yearly citations ΔL(max) during the entire citation period t (normal citation behavior). The citation period for these papers is less than 15 years and it is even 6-8 years in several cases. However, for papers with citation periods exceeding about 15 years, the growth behavior of citations does not follow the PNM in the entire citation period (anomalous citation behavior), and there are regions of citations in which the citation data may be described by the PNM. Normal and anomalous citation behaviors are attributed, respectively, to the occurrence and nonoccurrence of stationary nucleation of citations for the papers. The PNM also explains the growth and decay of citations ΔL per year of papers exhibiting normal citation behavior.

  16. Power-law citation distributions are not scale-free.

    Golosovsky, Michael

    2017-09-01

    We analyze time evolution of statistical distributions of citations to scientific papers published in the same year. While these distributions seem to follow the power-law dependence we find that they are nonstationary and the exponent of the power-law fit decreases with time and does not come to saturation. We attribute the nonstationarity of citation distributions to different longevity of the low-cited and highly cited papers. By measuring citation trajectories of papers we found that citation careers of the low-cited papers come to saturation after 10-15 years while those of the highly cited papers continue to increase indefinitely: The papers that exceed some citation threshold become runaways. Thus, we show that although citation distribution can look as a power-law dependence, it is not scale free and there is a hidden dynamic scale associated with the onset of runaways. We compare our measurements to our recently developed model of citation dynamics based on copying-redirection-triadic closure and find explanations to our empirical observations.

    The purpose of our study was to analyze scientific papers published by South Korean plastic surgeons in journals included in the Science Citation Index Expanded (SCIE), and to evaluate the publication and research activities of Korean plastic surgeon. We conducted a survey of SCIE papers in the field of plastic surgery published by South Korean authors between 2001 and 2010 using Web of Science software. We further analyzed these results according to the number of publications per year, journals, institution, and type of papers. We also compared the total number of citations to published scientific papers. We analyzed the rank of South Korea among other countries in representative journals. Overall, 667 papers were published by South Korean authors between 2001 and 2010. The number of publications increased dramatically from 2003 (n=31) to 2010 (n=139). Subsequently, the ten most productive Korean medical colleges were identified. All published papers received 2,311 citations and the citation to paper ratio was 3.49. The rank of Korea among other countries in terms of the number of published papers remained in the top 10 during the recent 10 years. Publication output of Korean plastic surgeon over the last 10 years showed a remarkable growth in terms of quantity and quality. Currently, Korea is among the top six countries in representative plastic surgery journals. Korean plastic surgeons have played a central role in this progress, and it is anticipated that they will continue to do so in the future.

    Full Text Available Using the interdisciplinary approach to Stevan Mokranjac’s Garlands [Rukoveti] and his successors in the Serbian choral music after World War II, while simultaneously relying on Dubravka Oraić Tolić’s Theory of Citation (1990, I have continued the work of distinguished scholars in the field of Serbian postwar music and their diverse analytical experiences. Whilst critically evaluating the existing analytical interpretations, in this article I have pointed to the alternative solutions and interpretations of the relevant issues of the organisation of the musical flow of Garlands and related formal types in almost all relevant musicotextual segments. Departing from the problems posed by the phenomena of intertextuality and citational procedures as elaborated by Dubravka Oraić Tolić, in this article I focus on their different embodiments as established in the relation between Stevan Mokranjac’s Garlands and garlands and similar forms of the second half of the 20th century; I also specify analytical methods and their creative application on the analysis of individual choral works. During this process, certain different types of the intertexual communication in the garlands written by members of different generations required more precise definition, i.e. additions and redefining of the existing terminology of the theory of citations, and an introduction of new terms. The selected analysed sample incorporates both the works that nowadays constitute the basis of the choral concert repertoire, and the works which are nowadays mostly neglected and not so attractive to performers and music theorists.Analytical issues discussed in this study have repeatedly pointed to the importance of Stevan Mokranjac’s Garlands as a paradigm for the authors of the second half of the 20th century, and repeated the vitality of his creative contributions to Serbian music. This has, in turn, reinforced the common knowledge on the work of Mokranjac as the

    The bibliography contains citations concerning emission standards and air quality standards applied to automobile emissions. Included are federal and state regulations and policies regarding these emission standards. Techniques to meet emission standards are also addressed, involving fuel injection, catalysts, alternate engines, and automotive fuel refinery operations. Studies concerning implementation of automobile emission standards explore economic and environmental effects, testing and inspection procedures, and the automobile industry point of view. Most of the citations refer to gasoline engines, but a few pertain to diesel and other fuels. (Contains 250 citations and includes a subject term index and title list.)

    We measured the potential impact of articles representing the International Symposium on Veterinary Epidemiology and Economics (ISVEE) plenary-session presentations in subsequent published literature. Between July 1, 2004 and November 9, 2004, we searched the Web of Science for citations in the scientific literature to all 99 plenary-session articles published in the proceedings of the previous nine ISVEEs (or in journal special issues dedicated to the ISVEE plenary articles). We used a 4-year window around the publication of each of the ISVEE proceedings. We located 187 citations for 37 (of the 99) articles. We infer that the ISVEE proceedings represent an important resource for veterinary epidemiology.

    2011-06-22

    High-energy physicists worldwide rely on online resources such as SPIRES and arXiv to perform gather research and share their own publications. SPIRES is a tool designed to search the literature within high-energy physics, while arXiv provides the actual full-text documents of this literature. In high-energy physics, papers are often ranked according to the number of citations they acquire - meaning the number of times a later paper references the original. This paper investigates the correlation between the number of times a paper is clicked in order to be downloaded and the number of citations it receives following the click. It explores how physicists truly read what they cite.

    To determine the rate with which diagnostic test accuracy studies that are published in a general radiology journal adhere to the Standards for Reporting of Diagnostic Accuracy Studies (STARD) 2015, and to explore the relationship between adherence rate and citation rate while avoiding confounding by journal factors. All eligible diagnostic test accuracy studies that were published in the Korean Journal of Radiology in 2011-2015 were identified. Five reviewers assessed each article for yes/no compliance with 27 of the 30 STARD 2015 checklist items (items 28, 29, and 30 were excluded). The total STARD score (number of fulfilled STARD items) was calculated. The score of the 15 STARD items that related directly to the Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2 was also calculated. The number of times each article was cited (as indicated by the Web of Science) after publication until March 2016 and the article exposure time (time in months between publication and March 2016) were extracted. Sixty-three articles were analyzed. The mean (range) total and QUADAS-2-related STARD scores were 20.0 (14.5-25) and 11.4 (7-15), respectively. The mean citation number was 4 (0-21). Citation number did not associate significantly with either STARD score after accounting for exposure time (total score: correlation coefficient = 0.154, p = 0.232; QUADAS-2-related score: correlation coefficient = 0.143, p = 0.266). The degree of adherence to STARD 2015 was moderate for this journal, indicating that there is room for improvement. When adjusted for exposure time, the degree of adherence did not affect the citation rate.

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

    Description of program or function: CITOPP processes the output file of the CITATION 3-D diffusion code. The program can plot axial, radial and circumferential flux distributions (in cylindrical geometry) in addition to the multiplication factor convergence. The flux distributions can be drawn for each group specified by the program and visualized on the screen. CITMOD processes both the output and the input files of the CITATION 3-D diffusion code. CITMOD can visualize both axial, and radial-angular models of the reactor described by CITATION input/output files. CITWI processes the input file (CIT.INP) of CITATION 3-D diffusion code. CIT.INP is processed to deduce the dimensions of the cell whose cross sections can be representative of the homonym reactor component in section 008 of CIT.INP

    Van Raan et al. (2010; arXiv:1003.2113) have proposed a new indicator (MNCS) for field normalization. Since field normalization is also used in the Leiden Rankings of universities, we elaborate our critique of journal normalization in Opthof & Leydesdorff (2010; arXiv:1002.2769) in this rejoinder concerning field normalization. Fractional citation counting thoroughly solves the issue of normalization for differences in citation behavior among fields. This indicator can also be used to obtain ...

  16. Statistical modelling of citation exchange between statistics journals.

    Varin, Cristiano; Cattelan, Manuela; Firth, David

    2016-01-01

    Rankings of scholarly journals based on citation data are often met with scepticism by the scientific community. Part of the scepticism is due to disparity between the common perception of journals' prestige and their ranking based on citation counts. A more serious concern is the inappropriate use of journal rankings to evaluate the scientific influence of researchers. The paper focuses on analysis of the table of cross-citations among a selection of statistics journals. Data are collected from the Web of Science database published by Thomson Reuters. Our results suggest that modelling the exchange of citations between journals is useful to highlight the most prestigious journals, but also that journal citation data are characterized by considerable heterogeneity, which needs to be properly summarized. Inferential conclusions require care to avoid potential overinterpretation of insignificant differences between journal ratings. Comparison with published ratings of institutions from the UK's research assessment exercise shows strong correlation at aggregate level between assessed research quality and journal citation 'export scores' within the discipline of statistics.

    To evaluate the production and utilization of Cochrane systematic reviews (CSRs) and to analyze its influential factors, so as to improve the capacity of translating CSRs into practice. All CSRs and protocols were retrieved from the Cochrane Library (Issue 2, 2011) and citation data were retrieved from SCI database. Citation analysis was used to analyze the situation of CSRs production and utilization. CSR publication had grown from an annual average of 32 to 718 documents. Only one developing country was among the ten countries with the largest amount of publications. High-income countries accounted for 83% of CSR publications and 90.8% of cited counts. A total 34.7% of CSRs had a cited count of 0, whereas only 0.9% had been cited more than 50 times. Highly cited CSRs were published in England, Australia, Canada, USA and other high-income countries. The countries with a Cochrane center or a Cochrane methodology group had a greater capability of CSRs production and citing than others. The CSRs addressing the topics of diseases were more than those targeted at public health issues. There was a big gap in citations of different interventions even on the same topic. The capability of CSR production and utilization grew rapidly, but varied among countries and institutions, which was affected by several factors such as the capability of research, resources and the applicability of evidence. It is important to improve evidence translation through educating, training and prioritizing the problems based on real demands of end users. © 2013 Wiley Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

  18. Tenure-Track Science Faculty and the 'Open Access Citation Effect'

    Directory of Open Access Journals (Sweden)

    R. Christopher Doty

    2013-02-01

    Full Text Available INTRODUCTION The observation that open access (OA articles receive more citations than subscription-based articles is known as the OA citation effect (OACE. Implicit in many OACE studies is the belief that authors are heavily invested in the number of citations their articles receive. This study seeks to determine what influence the OACE has on the decision-making process of tenure-track science faculty when they consider where to submit a manuscript for publication. METHODS Fifteen tenure-track faculty members in the Departments of Biology and Chemistry at the University of North Carolina at Chapel Hill participated in semi-structured interviews employing a variation of the critical incident tecnique. RESULTS Seven of the fifteen faculty members said they would consider making a future article freely-available based on the OACE. Due to dramatically different expectations with respect to the size of the OACE, however, only one of them is likely to seriously consider the OACE when deciding where to submit their next manuscript for publication. DISCUSSION Journal reputation and audience, and the quality of the editorial and review process are the most important factors in deciding where to submit a manuscript for publication. Once a subset of journals has satisfied these criteria, financial and access issues compete with the OACE in making a final decision. CONCLUSION In order to increase the number of OA materials, librarians should continue to emphasize depositing pre- and post-prints in disciplinary and institutional repositories and retaining the author rights prior to publication in order to make it possible to do so.

    Despite their recognized limitations, bibliometric assessments of scientific productivity have been widely adopted. We describe here an improved method to quantify the influence of a research article by making novel use of its co-citation network to field-normalize the number of citations it has received. Article citation rates are divided by an expected citation rate that is derived from performance of articles in the same field and benchmarked to a peer comparison group. The resulting Relative Citation Ratio is article level and field independent and provides an alternative to the invalid practice of using journal impact factors to identify influential papers. To illustrate one application of our method, we analyzed 88,835 articles published between 2003 and 2010 and found that the National Institutes of Health awardees who authored those papers occupy relatively stable positions of influence across all disciplines. We demonstrate that the values generated by this method strongly correlate with the opinions of subject matter experts in biomedical research and suggest that the same approach should be generally applicable to articles published in all areas of science. A beta version of iCite, our web tool for calculating Relative Citation Ratios of articles listed in PubMed, is available at https://icite.od.nih.gov.

    Full Text Available Abstract Background Systematic reviews summarize all pertinent evidence on a defined health question. They help clinical scientists to direct their research and clinicians to keep updated. Our objective was to determine the extent to which systematic reviews are clustered in a large collection of clinical journals and whether review type (narrative or systematic affects citation counts. Methods We used hand searches of 170 clinical journals in the fields of general internal medicine, primary medical care, nursing, and mental health to identify review articles (year 2000. We defined 'review' as any full text article that was bannered as a review, overview, or meta-analysis in the title or in a section heading, or that indicated in the text that the intention of the authors was to review or summarize the literature on a particular topic. We obtained citation counts for review articles in the five journals that published the most systematic reviews. Results 11% of the journals concentrated 80% of all systematic reviews. Impact factors were weakly correlated with the publication of systematic reviews (R2 = 0.075, P = 0.0035. There were more citations for systematic reviews (median 26.5, IQR 12 – 56.5 than for narrative reviews (8, 20, P Conclusions A few clinical journals published most systematic reviews. Authors cited systematic reviews more often than narrative reviews, an indirect endorsement of the 'hierarchy of evidence'.

  2. The Post-Embargo Open Access Citation Advantage: It Exists (Probably), Its Modest (Usually), and the Rich Get Richer (of Course).

    2016-01-01

    Many studies show that open access (OA) articles-articles from scholarly journals made freely available to readers without requiring subscription fees-are downloaded, and presumably read, more often than closed access/subscription-only articles. Assertions that OA articles are also cited more often generate more controversy. Confounding factors (authors may self-select only the best articles to make OA; absence of an appropriate control group of non-OA articles with which to compare citation figures; conflation of pre-publication vs. published/publisher versions of articles, etc.) make demonstrating a real citation difference difficult. This study addresses those factors and shows that an open access citation advantage as high as 19% exists, even when articles are embargoed during some or all of their prime citation years. Not surprisingly, better (defined as above median) articles gain more when made OA.

    Health research is one mechanism to improve population-level health and should generally match the health needs of populations. However, there have been limited data to assess the trends in national-level cardiovascular research output, even as cardiovascular disease [CVD] has become the leading cause of morbidity and mortality worldwide. We performed a time trends analysis of cardiovascular research publications (1999-2008) downloaded from Web of Knowledge using a iteratively-tested cardiovascular bibliometric filter with >90% precision and recall. We evaluated cardiovascular research publications, five-year running actual citation indices [ACIs], and degree of international collaboration measured through the ratio of the fractional count of addresses from one country against all addresses for each publication. Global cardiovascular publication volume increased from 40 661 publications in 1999 to 55 284 publications in 2008, which represents a 36% increase. The proportion of cardiovascular publications from high-income, Organization for Economic Cooperation and Development [OECD] countries declined from 93% to 84% of the total share over the study period. High-income, OECD countries generally had higher fractional counts, which suggest less international collaboration, than lower income countries from 1999-2008. There was an inverse relationship between cardiovascular publications and age-standardized CVD morbidity and mortality rates, but a direct, curvilinear relationship between cardiovascular publications and Human Development Index from 1999-2008. Cardiovascular health research output has increased substantially in the past decade, with a greater share of citations being published from low- and middle-income countries. However, low- and middle-income countries with the higher burdens of cardiovascular disease continue to have lower research output than high-income countries, and thus require targeted research investments to improve cardiovascular health.

    Full Text Available Evaluating the impact of a scholarly article is of great significance and has attracted great attentions. Although citation-based evaluation approaches have been widely used, these approaches face limitations e.g. in identifying anomalous citations patterns. This negligence would inevitably cause unfairness and inaccuracy to the article impact evaluation. In this study, in order to discover the anomalous citations and ensure the fairness and accuracy of research outcome evaluation, we investigate the citation relationships between articles using the following factors: collaboration times, the time span of collaboration, citing times and the time span of citing to weaken the relationship of Conflict of Interest (COI in the citation network. Meanwhile, we study a special kind of COI, namely suspected COI relationship. Based on the COI relationship, we further bring forward the COIRank algorithm, an innovative scheme for accurately assessing the impact of an article. Our method distinguishes the citation strength, and utilizes PageRank and HITS algorithms to rank scholarly articles comprehensively. The experiments are conducted on the American Physical Society (APS dataset. We find that about 80.88% articles contain contributed citations by co-authors in 26,366 articles and 75.55% articles among these articles are cited by the authors belonging to the same affiliation, indicating COI and suspected COI should not be ignored for evaluating impact of scientific papers objectively. Moreover, our experimental results demonstrate COIRank algorithm significantly outperforms the state-of-art solutions. The validity of our approach is verified by using the probability of Recommendation Intensity.

  5. A review on citation amnesia in depression and inflammation research.

    Once original scientific results are published the author has the "intellectual property" and may claim ownership. Discovery credit is one of the most important "rewards" for scientists and thus incorrect credits undermine the reward system of science. Scientists who publish should therefore give proper credit and acknowledge the primary sources. Failure to do so is regarded as "citation negligence", "the disregard syndrome", "citation amnesia", "plagiarism by omission", "bibliographic plagiarism" or "citation plagiarism", and may range from an unconscious or conscious "failure to credit a prior discoverer so as to give an improper impression of priority" to "the appropriation of another person's ideas or results without given proper credit". False discovery credit is considered to be "a menace to honest science", "a serious transgression" or "intellectual theft, be it intentional or not". This paper describes some examples of citation amnesia showing that scientists often fail to credit prior sources and give false discovery credit to other scientists. One example is the association between major depression and activated immuno-inflammatory pathways, a discovery by European groups and published in many papers since 1990. Now, 25 years later, it is commonplace that these theories are credited to secondary American sources whose work in "the last decade", did or did not examine these pathways in major depression. This gives an improper impression of priority of American-based scientists. Here it is proposed that this citation amnesia and plagiarism reinforced the wrong science and had negative effects on the development of immune-inflammatory biomarkers and new immune-related treatments for depression. It is concluded that journal editors should improve their citation standards to guarantee correct assignment of discovery credit for example by demanding a signed pledge from the authors that correct citations to the primary sources were made.

  7. Self-citations at the meso and individual levels: effects of different calculation methods.

    2010-03-01

    This paper focuses on the study of self-citations at the meso and micro (individual) levels, on the basis of an analysis of the production (1994-2004) of individual researchers working at the Spanish CSIC in the areas of Biology and Biomedicine and Material Sciences. Two different types of self-citations are described: author self-citations (citations received from the author him/herself) and co-author self-citations (citations received from the researchers' co-authors but without his/her participation). Self-citations do not play a decisive role in the high citation scores of documents either at the individual or at the meso level, which are mainly due to external citations. At micro-level, the percentage of self-citations does not change by professional rank or age, but differences in the relative weight of author and co-author self-citations have been found. The percentage of co-author self-citations tends to decrease with age and professional rank while the percentage of author self-citations shows the opposite trend. Suppressing author self-citations from citation counts to prevent overblown self-citation practices may result in a higher reduction of citation numbers of old scientists and, particularly, of those in the highest categories. Author and co-author self-citations provide valuable information on the scientific communication process, but external citations are the most relevant for evaluative purposes. As a final recommendation, studies considering self-citations at the individual level should make clear whether author or total self-citations are used as these can affect researchers differently.

    This paper defines and discusses two important types of citations, self-citation and mandatory citation, in engineering journals. Citation can be classified in three categories: optional; semi-mandatory; and mandatory. There are some negative and positive impacts for the authors' paper and journals' reputation if mandatory citation of a paper or set of papers is requested. These effects can be different based on the recommended papers for citing in the new research. Mandatory citation has various types discussed in this paper. Self-citation and its reasons and impacts are also discussed in the present study.

  17. Can Tweets Predict Citations? Metrics of Social Impact Based on Twitter and Correlation with Traditional Metrics of Scientific Impact

    Science.gov (United States)

    2011-01-01

    Background Citations in peer-reviewed articles and the impact factor are generally accepted measures of scientific impact. Web 2.0 tools such as Twitter, blogs or social bookmarking tools provide the possibility to construct innovative article-level or journal-level metrics to gauge impact and influence. However, the relationship of the these new metrics to traditional metrics such as citations is not known. Objective (1) To explore the feasibility of measuring social impact of and public attention to scholarly articles by analyzing buzz in social media, (2) to explore the dynamics, content, and timing of tweets relative to the publication of a scholarly article, and (3) to explore whether these metrics are sensitive and specific enough to predict highly cited articles. Methods Between July 2008 and November 2011, all tweets containing links to articles in the Journal of Medical Internet Research (JMIR) were mined. For a subset of 1573 tweets about 55 articles published between issues 3/2009 and 2/2010, different metrics of social media impact were calculated and compared against subsequent citation data from Scopus and Google Scholar 17 to 29 months later. A heuristic to predict the top-cited articles in each issue through tweet metrics was validated. Results A total of 4208 tweets cited 286 distinct JMIR articles. The distribution of tweets over the first 30 days after article publication followed a power law (Zipf, Bradford, or Pareto distribution), with most tweets sent on the day when an article was published (1458/3318, 43.94% of all tweets in a 60-day period) or on the following day (528/3318, 15.9%), followed by a rapid decay. The Pearson correlations between tweetations and citations were moderate and statistically significant, with correlation coefficients ranging from .42 to .72 for the log-transformed Google Scholar citations, but were less clear for Scopus citations and rank correlations.

  18. Modeling nonuniversal citation distributions: the role of scientific journals

    2014-01-01

    Whether a scientific paper is cited is related not only to the influence of its author(s) but also to the journal publishing it. Scientists, either proficient or less experienced, usually submit their most important work to prestigious journals which receive more citations than others. How to model the role of scientific journals in citation dynamics is of great importance. In this paper we address this issue through two approaches. One is the intrinsic heterogeneity of a paper determined by the impact factor of the journal publishing it. The other is the mechanism of a paper being cited which depends on its citations and prestige. We develop a model for citation networks via an intrinsic nodal weight function and an intuitive aging mechanism. The node’s weight is drawn from the distribution of impact factors of journals and the aging transition is a function of the citation and the prestige. The node-degree distribution of resulting networks shows nonuniversal scaling: the distribution decays exponentially for small degree and has a power-law tail for large degree, hence the dual behavior. The higher the impact factor of the journal, the larger the tipping point and the smaller the power exponent that are obtained. With the increase of the journal rank, this phenomenon will fade and evolve to pure power laws. (paper)

    2013-04-01

    Full Text Available Librarians and researchers have long used citation management systems as research tools to help scholars organize their work, improve workflows, and ultimately save time. For many years, RefWorks has been the dominant citation management tool in many parts of Canada: the maturity of the product and its integration with many scholarly databases reassures users that it works well with these resources. However, a number of competitors now offer citation management systems that are as strong as RefWorks but offer different features to the user, therefore warranting a comparison with this leading tool. This paper reviews RefWorks, Zotero, WizFolio, and Mendeley, which are all popular citation management systems that either have a long history of use or are now gaining traction in Canadian academic circles. To compare these tools, we examined their import capabilities as well as their organizing, searching, annotating, and sharing functions. This review will interest both librarians and researchers who are considering alternative citation management systems at either the personal or organizational level.

    Little has been published about the historical development of scientific evidence in the physical activity (PA) and public health research field. The study aimed to examine the evolution of knowledge in this field. A structured literature review using formal citation network analysis methods was conducted in June-2016. Using a list of influential PA publications identified by domain experts, a snowball sampling technique was used to build a compact citation network of 141 publications that represents the backbone of the field. Articles were coded by study type and research team characteristics, then analyzed by visualizing the citation network and identifying research clusters to trace the evolution of the field. The field started in the 1950s, with a health sciences focus and strong North American and European leadership. Health outcome studies appeared most frequently in the network and policy and interventions least. Critical articles on objective measurement and public policy have influenced the progress from an emphasis on health outcomes research at early stages in the field to the more recent emerging built environment and global monitoring foci. There is only modest cross-citation across types of study. To our knowledge, this paper is the first to systematically describe the development of research on PA and public health. The key publications include fundamental ideas that remain citable over time, but notable research and dissemination gaps exist and should be addressed. Increasing collaboration and communication between study areas, encouraging female researchers, and increasing studies on interventions, evaluation of interventions and policy are recommended.

  1. Lovely but dangerous: The impact of patent citations on patent duration

    OpenAIRE

    Maurseth, Per Botolf

    2001-01-01

    - What is the impact of patent citations on patent renewal behaviour? Patent citations are commonly used as an indicator of technology spillovers. For cited patents therefore, patent citations have a potentially ambiguous impact. On the one hand, patent citations may indicate a scientific breakthrough, a high value of the cited patent and therefore a long survival period. On the other hand, patent citations may indicate competing innovations that render the cited patent obsolete. By discri...

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

    2014-01-01

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

    2006-01-01

    Medycyna Pracy, a Polish bimonthly published since 1950, forms a long-standing documentation of studies carried out in the area of workers' health protection. The journal is primarily addressed to occupational health physicians and work hygiene specialists in Poland. It is indexed by numerous foreign information services (e.g., MEDLINE, EMBASE, BIOSIS PREVIEWS, BIOLOGICAL ABSTRACTS, SCOPUS) and thus promotes Polish research in occupational medicine throughout the world. The quantitative analysis for the years 1996-2005, grounded on the SCOPUS database, presents an average number of citations concerning a given volume, frequency of citations, articles most frequently cited, and countries, in which articles published in Medycyna Pracy have been referred to. A growing number of citations observed in the recent years signify the importance of issues investigated and discussed in the journal as well as its role in the world-wide circulation of scientific information.

    Thomson Reuters will launch its new Book Citation Index later this year. Projected to include 25,000 volumes from major publishers and university presses in science, social science, and the humanities, the Book Citation Index will cover scholarly books (both series and nonseries) that present original research or literature reviews. The current effort regarding the science section is focused on books published from 2005 to the present. AGU has sent copies of its catalog for inclusion in the Book Citation Index, but the final selection will be made by Thomson Reuters, using its internal selection criteria, which may be found at http://wokinfo.com/wok/media/pdf/BKCI-SelectionEssay_web.pdf.

  6. Citation practices in Slovak and English linguistic research papers

    Directory of Open Access Journals (Sweden)

    Walková Milada

    2017-12-01

    Full Text Available Citation in research articles is an important gateway to acceptance by academic community. When citing others, scholars follow the conventions of the genre, of the academic discipline, and of their culture. This paper focuses on the cultural aspects of citation by comparing and contrasting a corpus of linguistic papers written in English and in Slovak. The results show that while English native writers prefer making their papers more objective through a higher incidence of generalisations and reporting verbs denoting the process of research, Slovak native writers opt for making the cited authors more visible by a greater amount of integral citations and reporting verbs denoting mental states and processes. A higher number of quotations, including floating quotations, suggests that Slovak scholars have a high regard for the work of others.

    This study investigated the professional impact of "Japanese Journal of Psychology." Thirty four psychological journals written in Japanese were selected to register articles in a new database. This database included approximately 23,900 articles published through 2010. 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.

    Full Text Available It is generally believed that the number of citations to an article can positively be correlated to its free online availability. In the present study, we investigated the possible impact of academic social networks on the number of citations. We chose the social web service “ResearchGate” as a case. This website acts both as a social network to connect researchers, and at the same time, as an open access repository to publish post-print version of the accepted manuscripts and final versions of open access articles. We collected the data of 1823 articles published by the authors from four different universities. By analyzing these data, we showed that although different levels of full text availability are observed for the four universities, there is always a significant positive correlation between full text availability and the citation count. Moreover, we showed that both post-print version and publisher’s version (i.e., final published version of the archived manuscripts receive more citations than non-OA articles, and the difference in the citation counts of post-print manuscripts and publisher’s version articles is nonsignificant.

    The method which has evolved over the years for making power reactor calculations is the multigroup diffusion method. The CITATION code is designed to solve multigroup neutronics problems with application of the finite-difference diffusion theory approximation to neutron transport in up to three-dimensional geometry. The first part of this paper presents information about the mathematical equations programmed along with background material and certain displays to convey the nature of some of the formulations. The results obtained with the CITATION code regarding the neutron and burnup core analysis for a typical PWR reactor are presented in the second part of this paper. (author)

    2018-01-01

    Specialized and emerging fields of research infrequently cross disciplinary boundaries and would benefit from frameworks, methods, and materials informed by other fields. Document co-citation analysis, a method developed by bibliometric research, is demonstrated as a way to help identify key literature for cross-disciplinary ideas. To illustrate the method in a useful context, we mapped peer-recognized scholarship related to systems thinking. In addition, three procedures for validation of co-citation networks are proposed and implemented. This method may be useful for strategically selecting information that can build consilience about ideas and constructs that are relevant across a range of disciplines. PMID:29308433

  11. Longitudinal Trends in Internationalisation, Collaboration Types, and Citation Impact: A Bibliometric Analysis of Seven LIS Journals (1980-2008

    Directory of Open Access Journals (Sweden)

    Sei-Ching Joanna Sin

    2011-06-01

    Full Text Available Journal publication is a core avenue for sharing research in the LIS field. Effective scholarly communication is beneficial to the growth of a discipline. Bibliometrics research shows that articles in prestigious international journals are predominantly those of authors based in a few nations, however. Papers from authors outside the established nations are likely to be cited less often. This study analysed the longitudinal changes in geographical patterns of authorship, collaboration types, and factors affecting the citation impact of seven top LIS journals over a period of 29 years. In addition to data from all nations, this paper includes specific findings relating to Asian countries. Analysis of 8,140 papers shows that the internationalisation level in the sample set has increased in terms of number of nations represented and in a decreasing Gini coefficient. The presence of Asian nations such as Taiwan and Singapore as top contributing countries is particularly notable in the past 10 years. Domestic collaboration is found to be the dominant type of authorship pattern. In terms of citation impact as measured by citation counts, logistic regression was used to test the effects of author continent, country income level, collaboration type, publication year, and number of authors. Papers from lower-income countries or from Asian or European authors are found less likely to be ‘more cited.’ International and domestic collaboration had a positive relation with citation counts. A practical implication is that authors may consider international collaboration as a way to increase the visibility and impact of their research. Nevertheless, the reasons behind such differential citation impact require more exploration. Invisible colleges, the strengths of weak ties, and the geographic scope of a paper are some factors to be further examined. It is hoped that more research can help identify and overcome barriers in scholarly communication so as to

    2013-01-01

    Background In times of globalization there is an increasing use of English in the medical literature. The aim of this study was to analyze the influence of English-language articles in multi-language medical journals on their international recognition – as measured by a lower rate of self-citations and higher impact factor (IF). Methods and Findings We analyzed publications in multi-language journals in 2008 and 2009 using the Web of Science (WoS) of Thomson Reuters (former Institute of Scientific Information) and PubMed as sources of information. The proportion of English-language articles during the period was compared with both the share of self-citations in the year 2010 and the IF with and without self-citations. Multivariable linear regression analysis was performed to analyze these factors as well as the influence of the journals‘ countries of origin and of the other language(s) used in publications besides English. We identified 168 multi-language journals that were listed in WoS as well as in PubMed and met our criteria. We found a significant positive correlation of the share of English articles in 2008 and 2009 with the IF calculated without self-citations (Pearson r=0.56, p = 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

    2017-10-01

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

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

    2016-01-01

    We assessed citation of prior research over time and the association of citation with the agreement of results between the trial being reported and the prior trial. Groups of pharmacologic trials in cardiovascular disease were created using meta-analyses, and we assessed citation within these groups. We calculated the proportion of prior trials cited, the proportion of study participants captured in citations, and agreement of results between citing and cited trials. Analysis included 86 meta-analyses with 580 trials published between 1982 and 2011. Reports of trials cited 25% (median; 95% confidence interval [CI], 23-27%) of prior trials, capturing 31% (95% CI, 25-36%) of trial participants. Neither measure differed by publication of the citing trial before vs. after 2005. Prior trials with results that agreed with the reports of trials (supportive trials) were significantly more likely to be cited than nonsupportive trials (relative risk 1.45; 95% CI, 1.30-1.61, P < 0.001). Selective undercitation of prior research continues; three quarters of existing evidence is ignored. This source of waste may result in unnecessary, unethical, and unscientific studies.

  17. Citation classics in suicide and life threatening behavior: a research note.

    Science.gov (United States)

    Stack, Steven

    2012-12-01

    The number of citations a scholarly work receives is a common measure of its impact on the scientific literature; "citation classics" are the most highly cited works. The content of Suicide and Life-Threatening Behavior (SLTB) citation classics is described here. The impact of SLTB citation classics is compared to their counterparts in journals having published the most suicide papers. All data are from the ISI electronic venue on the Web of Science and refer to the number of citations the top 1% of works received in each of ten journals from 1975 through August 10, 2011. Among all ten journals, SLTB ranked first in the number of works on suicide. The principle theme of half of SLTB suicide classics was literature review. The median number of citations for SLTB citation classics (top 1%) was 121.5, with a range between 96 and 279 citations, but classics from generalized psychiatric journals received more citations as anticipated. Journal impact factors explained 73% of the variance in classic's citation counts across journals. On average, suicide classics received 30% more citations than all classics. Among a second group of five specialized suicide journals, however, SLTB ranked first in average 5-year impact. Although SLTB produced the highest number of suicide articles of any journal, SLTB's citation classics received fewer citations than suicide classics in high-impact/prestige, general journals. Future work is needed to assess what predicts which SLTB articles ultimately become citation classics. © 2012 The American Association of Suicidology.

  18. Adverse event reporting in cancer clinical trial publications.

    Reporting adverse events is a critical element of a clinical trial publication. In 2003, the Consolidated Standards of Reporting Trials (CONSORT) group generated recommendations regarding the appropriate reporting of adverse events. The degree to which these recommendations are followed in oncology publications has not been comprehensively evaluated. A review of citations from PubMed, Medline, and Embase published between Jan 1, 2009 and December 31, 2011, identified eligible randomized, controlled phase III trials in metastatic solid malignancies. Publications were assessed for 14 adverse event-reporting elements derived from the CONSORT harms extension statement; a completeness score (range, 0 to 14) was calculated by adding the number of elements reported. Linear regression analysis identified which publication characteristics associated with reporting completeness. A total of 175 publications, with data for 96,125 patients, were included in the analysis. The median completeness score was eight (range, three to 12). Most publications (96%) reported only adverse events occurring above a threshold rate or severity, 37% did not specify the criteria used to select which adverse events were reported, and 88% grouped together adverse events of varying severity. Regression analysis revealed that trials without a stated funding source and with an earlier year of publication had significantly lower completeness scores. Reporting of adverse events in oncology publications of randomized trials is suboptimal and characterized by substantial selectivity and heterogeneity. The development of oncology-specific standards for adverse event reporting should be established to ensure consistency and provide critical information required for medical decision-making.

Quantitative estimates of economic benefits to the gas industry and its customers are provided for 60 of the technologies. The net present value is approximately $7.4 billion. While not accounting for R and D efforts in progress, the figure is 4.3 times the cumulative net present value of the cost of the entire GRI R and D program from its inception and represents a rate of return to ratepayers of almost 20%. When compared with the cost of completed R and D, the benefit-to-cost ratio is 8.1 to 1

  1. Vectorization of three-dimensional neutron diffusion code CITATION

    International Nuclear Information System (INIS)

    Harada, Hiroo; Ishiguro, Misako

    1985-01-01

    Three-dimensional multi-group neutron diffusion code CITATION has been widely used for reactor criticality calculations. The code is expected to be run at a high speed by using recent vector supercomputers, when it is appropriately vectorized. In this paper, vectorization methods and their effects are described for the CITATION code. Especially, calculation algorithms suited for vectorization of the inner-outer iterative calculations which spend most of the computing time are discussed. The SLOR method, which is used in the original CITATION code, and the SOR method, which is adopted in the revised code, are vectorized by odd-even mesh ordering. The vectorized CITATION code is executed on the FACOM VP-100 and VP-200 computers, and is found to run over six times faster than the original code for a practical-scale problem. The initial value of the relaxation factor and the number of inner-iterations given as input data are also investigated since the computing time depends on these values. (author)

    Objective We aim to identify duplicate pairs of Medline citations, particularly when the documents are not identical but contain similar information. Materials and methods Duplicate pairs of citations are identified by comparing word n-grams in pairs of documents. N-grams are modified using two approaches which take account of the fact that the document may have been altered. These are: (1) deletion, an item in the n-gram is removed; and (2) substitution, an item in the n-gram is substituted with a similar term obtained from the Unified Medical Language System  Metathesaurus. N-grams are also weighted using a score derived from a language model. Evaluation is carried out using a set of 520 Medline citation pairs, including a set of 260 manually verified duplicate pairs obtained from the Deja Vu database. Results The approach accurately detects duplicate Medline document pairs with an F1 measure score of 0.99. Allowing for word deletions and substitution improves performance. The best results are obtained by combining scores for n-grams of length 1–5 words. Discussion Results show that the detection of duplicate Medline citations can be improved by modifying n-grams and that high performance can also be obtained using only unigrams (F1=0.959), particularly when allowing for substitutions of alternative phrases.

  18. Discrete Lognormal Model as an Unbiased Quantitative Measure of Scientific Performance Based on Empirical Citation Data

    Assessing the career performance of scientists has become essential to modern science. Bibliometric indicators, like the h-index are becoming more and more decisive in evaluating grants and approving publication of articles. However, many of the more used indicators can be manipulated or falsified by publishing with very prolific researchers or self-citing papers with a certain number of citations, for instance. Accounting for these factors is possible but it introduces unwanted complexity that drives us further from the purpose of the indicator: to represent in a clear way the prestige and importance of a given scientist. Here we try to overcome this challenge. We used Thompson Reuter's Web of Science database and analyzed all the papers published until 2000 by ~1500 researchers in the top 30 departments of seven scientific fields. We find that over 97% of them have a citation distribution that is consistent with a discrete lognormal model. This suggests that our model can be used to accurately predict the performance of a researcher. Furthermore, this predictor does not depend on the individual number of publications and is not easily ``gamed'' on. The authors acknowledge support from FCT Portugal, and NSF grants

  19. Power laws in citation distributions: evidence from Scopus.

    Science.gov (United States)

    Brzezinski, Michal

    Modeling distributions of citations to scientific papers is crucial for understanding how science develops. However, there is a considerable empirical controversy on which statistical model fits the citation distributions best. This paper is concerned with rigorous empirical detection of power-law behaviour in the distribution of citations received by the most highly cited scientific papers. We have used a large, novel data set on citations to scientific papers published between 1998 and 2002 drawn from Scopus. The power-law model is compared with a number of alternative models using a likelihood ratio test. We have found that the power-law hypothesis is rejected for around half of the Scopus fields of science. For these fields of science, the Yule, power-law with exponential cut-off and log-normal distributions seem to fit the data better than the pure power-law model. On the other hand, when the power-law hypothesis is not rejected, it is usually empirically indistinguishable from most of the alternative models. The pure power-law model seems to be the best model only for the most highly cited papers in "Physics and Astronomy". Overall, our results seem to support theories implying that the most highly cited scientific papers follow the Yule, power-law with exponential cut-off or log-normal distribution. Our findings suggest also that power laws in citation distributions, when present, account only for a very small fraction of the published papers (less than 1 % for most of science fields) and that the power-law scaling parameter (exponent) is substantially higher (from around 3.2 to around 4.7) than found in the older literature.

    Team science involving multidisciplinary and multi-institutional collaboration is increasingly recognized as a means of strengthening the quality of scientific research. The aim of this study was to assess associations between various forms of collaboration and the citation impact of published radiology research. In 2010, 876 original research articles published in Academic Radiology, the American Journal of Roentgenology, JACR, and Radiology were identified with at least one radiology-affiliated author. All articles were manually reviewed to extract features related to all authors' disciplines and institutions. Citations to these articles through September 2016 were extracted from Thomson Reuters Web of Science. Subsequent journal article citation counts were significantly higher (P < .05) for original research articles with at least seven versus six or fewer authors (26.2 ± 30.8 versus 20.3 ± 23.1, respectively), with authors from multiple countries versus from a single country (32.3 ± 39.2 versus 22.0 ± 25.0, respectively), with rather than without a nonuniversity collaborator (28.7 ± 38.6 versus 22.4 ± 24.9, respectively), and with rather than without a nonclinical collaborator (26.5 ± 33.1 versus 21.9 ± 24.4, respectively). On multivariate regression analysis, the strongest independent predictors of the number of citations were authors from multiple countries (β = 9.14, P = .002), a nonuniversity collaborator (β = 4.80, P = .082), and at least seven authors (β = 4.11, P = .038). With respect to subsequent journal article citations, various forms of collaboration are associated with greater scholarly impact of published radiology research. To enhance the relevance of their research, radiology investigators are encouraged to pursue collaboration across traditional disciplinary, institutional, and geographic boundaries.

    Acute appendicitis is one of the most commonly encountered emergency surgical conditions. An understanding of the most highly cited research works in this field is key to good evidence based clinical practice. To perform a bibliometric analysis on the 100 most frequently cited articles in the field of acute appendicitis. The database of the Institute for Scientific Information (ISI) Web of Science Expanded citation index was searched to identify the 100 most frequently cited articles in the field of acute appendicitis. The web of science expanded citation index tracks article citations made since 1946. The top 100 most frequently cited articles were selected for analysis in this series. The most frequently cited article was cited 649 times and the least cited three article 93 times. The average number of citations per article was 167.74. The top 100 cited articles originated from 17 countries. Over half of the papers originated from the USA. Fifty-one of the papers concentrated on diagnostics of acute appendicitis. Thirty-six papers looked at the treatment of acute appendicitis with 30 of these dealing with the surgical management of the disease. There were 6 studies at level 1a, 20 studies at level 1b and 43,5,17 and 9 studies at levels 2, 3, 4 and 5 respectively. Bibliometric analysis of the citation classics in a given field can provide interesting insights into the relationship between the quality of research outputs and clinical practice. The study of acute appendicitis remains an active field of research with a growing body of higher quality evidence underpinning our clinical practice.

    The National HIV/AIDS Strategy (NHAS) emphasizes the use of technology to facilitate coordination of comprehensive care for people with HIV. We examined the effect of six health information technology (HIT) interventions in a Ryan White-funded Special Projects of National Significance (SPNS) on care completion services, engagement in HIV care, and viral suppression. Interventions included use of surveillance data to identify out-of-care individuals, extending access to electronic health records to support service providers, use of electronic laboratory ordering and prescribing, and development of a patient portal. Data from a sample of electronic patient records from each site were analyzed to assess changes in utilization of comprehensive care (prevention screening, support service utilization), engagement in primary HIV medical care (receipt of services and use of antiretroviral therapy), and viral suppression. We used weighted generalized estimating equations to estimate outcomes while accounting for the unequal contribution of data and differences in the distribution of patient characteristics across sites and over time. We observed statistically significant changes in the desired direction in comprehensive care utilization and engagement in primary care outcomes targeted by each site. Five of six sites experienced statistically significant increases in viral suppression. These results provide additional support for the use of HIT as a valuable tool for achieving the NHAS goal of providing comprehensive care for all people living with HIV. HIT has the potential to increase utilization of services, improve health outcomes for people with HIV, and reduce community viral load and subsequent transmission of HIV. © The Author 2014.

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

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

  5. Roles of the Cited Author in Citations of the Literature Review by EFL Postgraduates

    Full Text Available The study analysed the clauses of the integral citations to identify the functional roles of the cited author[1] used by EFL postgraduates. The Systemic Functional Linguistics (SFL was adopted in analysing the clauses qualitatively. A purposeful sampling was utilized in choosing the literature review of 20 PhD theses in Information Technology and Applied Linguistics at a public Malaysian university. In terms of the interpersonal meanings, the cited author functions as a ‘Subject’, a ‘Complement’, and an ‘Adjunct’. For the  experiential meanings, the cited author has functions based on the processes types used in each clause, including an ‘Actor’ and a ‘Goal’ with material processes, a ‘Senser’ and a ‘Phenomenon’ with mental processes, a ‘Sayer’ and a ‘Verbiage’ with verbal processes, a ‘Behaver’ with behavioural processes, a ‘Carrier’, a ‘ Carrier: Possessor’, an ‘Attribute’, a ‘Token’, and a ‘Value’ with relational processes, and an ‘Agent: Attributor’ with causative processes. Other functions related to the Circumstantial under the experiential meanings involved an ‘Agent’, a ‘Location (Place’, a ‘Manner: Comparison’, an ‘Accompaniment’ and a ‘Matter’. Field and tenor affected the role of the cited author; field’s effect was demonstrated by using a higher number of the cited author’s roles in the Applied Linguistics, whereas tenor’s influence was illustrated in assigning similar roles to the cited author in the Applied Linguistics and Information Technology. These results extend the findings of previous studies, help students in using citations in academic writing, and present more outputs about citations that can be employed pedagogically.

    2018-02-01

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

    Chemistry researchers are frequently evaluated on the perceived significance of their work with the citation count as the most commonly-used metric for gauging this property. Recent studies have called for a broader evaluation of significance that includes more nuanced bibliometrics as well as altmetrics to more completely evaluate scientific research. To better understand the relationship between metrics and peer judgements of significance in chemistry, we have conducted a survey of chemists to investigate their perceptions of previously published research. Focusing on a specific issue of the Journal of the American Chemical Society published in 2003, respondents were asked to select which articles they thought best matched importance and significance given several contexts: highest number of citations, most significant (subjectively defined), most likely to share among chemists, and most likely to share with a broader audience. The answers to the survey can be summed up in several observations. The ability of respondents to predict the citation counts of established research is markedly lower than the ability of those counts to be predicted by the h-index of the corresponding author of each article. This observation is conserved even when only considering responses from chemists whose expertise falls within the subdiscipline that best describes the work performed in an article. Respondents view both cited papers and significant papers differently than papers that should be shared with chemists. We conclude from our results that peer judgements of importance and significance differ from metrics-based measurements, and that chemists should work with bibliometricians to develop metrics that better capture the nuance of opinions on the importance of a given piece of research.

  9. The Pagerank-Index: Going beyond Citation Counts in Quantifying Scientific Impact of Researchers.

    Full Text Available Quantifying and comparing the scientific output of researchers has become critical for governments, funding agencies and universities. Comparison by reputation and direct assessment of contributions to the field is no longer possible, as the number of scientists increases and traditional definitions about scientific fields become blurred. The h-index is often used for comparing scientists, but has several well-documented shortcomings. In this paper, we introduce a new index for measuring and comparing the publication records of scientists: the pagerank-index (symbolised as π. The index uses a version of pagerank algorithm and the citation networks of papers in its computation, and is fundamentally different from the existing variants of h-index because it considers not only the number of citations but also the actual impact of each citation. We adapt two approaches to demonstrate the utility of the new index. Firstly, we use a simulation model of a community of authors, whereby we create various 'groups' of authors which are different from each other in inherent publication habits, to show that the pagerank-index is fairer than the existing indices in three distinct scenarios: (i when authors try to 'massage' their index by publishing papers in low-quality outlets primarily to self-cite other papers (ii when authors collaborate in large groups in order to obtain more authorships (iii when authors spend most of their time in producing genuine but low quality publications that would massage their index. Secondly, we undertake two real world case studies: (i the evolving author community of quantum game theory, as defined by Google Scholar (ii a snapshot of the high energy physics (HEP theory research community in arXiv.

    Knowledge organization (KO) and bibliometrics have traditionally been seen as separate subfields of library and information science, but bibliometric techniques make it possible to identify candidate terms for thesauri and to organize knowledge by relating scientific papers and authors to each...... be considered superior for all purposes. The main difference between traditional knowledge organization systems (KOSs) and maps based on citation analysis is that the first group represents intellectual KOSs, whereas the second represents social KOSs. For this reason bibliometric maps cannot be expected ever...... other and thereby indicating kinds of relatedness and semantic distance. It is therefore important to view bibliometric techniques as a family of approaches to KO in order to illustrate their relative strengths and weaknesses.

    The differences in conceptual citation frequency are examined between quantum mechanics literature and elementary particle physics literature. Using a sample based on increments of 5 years, 7 contrast tests were generated over a literature period of 35 years. A Dunn planned comparison procedure indicated a statistical difference in years 5 and 10 but no differences were found in the remaining years. The results must be weighed against the time frames in which the literature was produced but clearly point to an initial difference in the two areas. Additional work is required to reevaluate the findings and to investigate the conceptual citation frequency issue further. The frequency distribution generated approximates a cumulative advantage process. (author)

  5. Less Citation, Less Dissemination: The Case of French Psychoanalysis

    Full Text Available We contribute to inquiries about the visibility of globalized psychoanalytic research in the digital era (cf. Stepansky 2009 by adopting a comparative perspective on a specific geographic area of historical importance for psychoanalysis: France. The largely digital globalized psychoanalytic research field relies on standard bibliometric measures of journal quality (Impact Factor, SJR, etc.,which depend on the number and type of academic cites received by a journal. Thus, citing shapes academic publishing space by differentially valuing its component journals. Conversely, not to cite practically means not to engage with the field. Hence, we took citedness rate as a proxy for global visibility.By drawing on an original database created by one of us, we determined the global citational visibility of French vs. Anglo- American psychoanalytic productions (respective global outreach; and we related it to a first look at French vs. Anglo-American citation practices (geographic breakdown of article cites.We found that,on a 15 - year period,the global outreach(citedness rate of French articles is ten times smaller than that of Anglo - American articles;and that French articles are cited in Anglo - American journals five times more than Anglo - American articles in French journals– which in turn don’ t seem to cite their French peers very often.These specific French citation practices could be explained by the implicit modes of reference at work in clinical settings shaped by rich theoretical and clinical local legacies.We conclude by considering that this situation presents French psychoanalytic research with a formidable opportunityfor increased citational visibility.

    2010-09-01

    Biomedical journals are the most used and important venue to disseminate and interchange scientific information, and evaluation is an important component. A bibliometric study was conducted on the productivity, visibility and citation analysis of the Revista Peruana de Medicina Experimental y Salud Pública (RPMESP), from 2002 to 2009. During this period, the RPMESP published about 62 documents per year, 55.3% were research articles. The visibility of RPMESP, determined among three databases (SISBIB-UNMSM, SciELO-Peru, and REDALYC), was irregular, increasing on July 2006, with the highest access on October 2009 (117,618 hits). 43.0% of publications were cited. The calculated impact factor in ISI journals was 0.04 in 2009. In conclusion, the citation of RPMESP shows a slowly growing during the period 2002-2009. It is hoped that the RPMESP increase its visibility and impact after its inclusion in MEDLINE.

    We describe the ongoing citations to biomedical articles affected by scientific misconduct, and characterize the papers that cite these affected articles. The citations to 102 articles named in official findings of scientific misconduct during the period of 1993 and 2001 were identified through the Institute for Scientific Information Web of Science database. Using a stratified random sampling strategy, we performed a content analysis of 603 of the 5,393 citing papers to identify indications of awareness that the cited articles affected by scientific misconduct had validity issues, and to examine how the citing papers referred to the affected articles. Fewer than 5% of citing papers indicated any awareness that the cited article was retracted or named in a finding of misconduct. We also tested the hypothesis that affected articles would have fewer citations than a comparison sample; this was not supported. Most articles affected by misconduct were published in basic science journals, and we found little cause for concern that such articles may have affected clinical equipoise or clinical care.

    Near-infrared spectroscopy (NIRS) studies through citation trends are investigated of literature concerning only the brain function measurement and its methodology together with NIRS principle, technological development, present state and future view. Investigation is conducted firstly for the survey of important author name of those concerned papers in Web of Science and Google Scholar with search words of NIRS, brain and optical topography as an option. Second, >100 papers of those authors citing any of them are picked up and their papers are ranked in accordance with Web of Science citation number, of which top-nineteen are presented here. Impact and epoch making papers are reviewed with explanations of: the establishment of measuring technology of cerebral blood flow change and subsequent brain function by NIRS; development with multi-channel detection; simultaneous measurement with other imaging modalities; examination of NIRS validity; spatial analysis of NIRS; and measurement of brain function. The highest times of citation are 1,238 of the paper by F. F. Jobsis in 'Science' (1977). It should be noted that 10 of top 19 papers are those by Japanese authors. However, review articles omitted in the present literature survey are mostly described by foreign authors: an effort to systemize the concerned fields might be required in this country. (K.T.)

    Objective To identify the 50 top-cited spine articles from mainland China and to analyze their main characteristics. Methods Web of Science was used to identify the 50 top-cited spine articles from mainland China in 27 spine-related journals. The title, year of publication, number of citations, journal, anatomic focus, subspecialty, evidence level, city, institution and author were recorded. Results The top 50 articles had 29-122 citations and were published in 11 English-language journals; most (32) were published in the 2000s. The journal Spine had the largest number of articles and The Lancet had the highest impact factor. The lumber spine was the most discussed anatomic area (18). Degenerative spine disease was the most common subspecialty topic (22). Most articles were clinical studies (29); the others were basic research (21). Level IV was the most common evidence level (17). Conclusions This list indicates the most influential articles from mainland China in the global spine research community. Identification of these articles provides insights into the trends in spine care in mainland China and the historical contributions of researchers from mainland China to the international spine research field.

  11. Mixing journal, article, and author citations, and other pitfalls in the bibliographic impact factor

    2003-01-01

    Full Text Available News of the death of biomedical journals seem premature. Revamped traditional scientific journals remain highly valued sources and vehicles of information, critical debate, and knowledge. Some analyses seem to place a disproportionate emphasis on technological and formal issues, as compared to the importance ascribed to matters of power. Not all journals must necessarily have a large circulation. There are many examples of efficient, high-quality journals with a great impact on relatively small audiences for whom the journal is thought-provoking, useful, and pleasant to read. How can we achieve a better understanding of an article?s spectrum of impacts? A certain mixing of three distinct entities (journals, articles, and authors has often pervaded judgments. Data used by the Institute for Scientific Information present weaknesses in their accuracy. The two-year limit for citations to count towards the bibliographic impact factor favors "fast-moving", "basic" biomedical disciplines and is less appropriate for public health studies. Increasing attention is given to the specific number of citations received by each individual article. It is possible to make progress towards more valid, accurate, fair, and relevant assessments.

  12. The use of citation indicators to identify and support high-quality research in Poland.

    Pilc, Andrzej

    2008-01-01

    In large, mostly English-speaking countries, where the "critical mass" of scientists working in different subfields of science is achieved, the peer review system may be sufficient to assess the quality of scientific research. However, in smaller countries, outside the Anglo-American circle, it is important to introduce different systems to identify research of high quality. In Poland, a parametric system for assessing the quality of research has been introduced. It was largely based on the impact factor of scientific journals. While the use of this indicator to assess research quality is highly questionable, the implementation of the system in the Polish reality is even worse. Therefore it is important to change and improve the system currently used by the Ministry of Science and Higher Education to both evaluate and, more importantly, finance science in Poland. Here, a system based on three factors, i.e. the impact factor, the institutional h-index, and the institutional number of citations, is proposed. The scientific quality of institutions in Division VI: Medical Sciences of the Polish Academy of Sciences were evaluated and the results were compared with the existing system. Moreover, a method to identify high-quality researchers and institutions at the national level based on the quantity of highly cited papers is shown. Additionally, an attempt to identify the highest quality Polish research on an international level is proposed. This is based on the number of individual citations, the individual h-index, the number of publications, and the priority of the discovery.

    1978-01-01

    This two-part report provides an essentially complete listing of radioactive occurrences in Colorado, with a comprehensive bibliography and bibliographic cross-indexes. Part 1 lists approximately 3000 known radioactive occurrences with their locations and brief accounts of the geology, mineralogy, radioactivity, host rock, production data, and source of data for each. The occurrences are classified by host rock and plotted on U.S. Geological Survey 1/sup 0/ x 2/sup 0/ topographic quadrangle maps with a special 1 : 100,000-scale base map for the Uravan mineral belt. Part 2 contains the bibliography of approximately 2500 citations on radioactive mineral occurrences in the state, with cross-indexes by county, host rock, and the special categories of ''Front Range,'' ''Colorado Plateau,'' and ''thorium.'' The term ''occurrence'' as used in this report is defined as any site where the concentration of uranium or thorium is at least 0.01% or where the range of radioactivity is greater than twice the background radioactivity. All citations and occurrence data are stored on computer diskettes for easy retrieval, correction, and updating.

    Peer reviewers sometimes request that authors cite their work, either appropriately or via coercive self-citation to highlight the reviewers' work. The objective of this study was to determine in peer reviews submitted to one biomedical journal (1) the extent of peer reviewer self-citation; (2) the proportion of reviews recommending revision or acceptance versus rejection that included reviewer self-citations; and (3) the proportion of reviewer self-citations versus citations to others that included a rationale. Peer reviews for manuscripts submitted in 2012 to the Journal of Psychosomatic Research were evaluated. Data extraction was performed independently by two investigators. There were 616 peer reviews (526 reviewers; 276 manuscripts), of which 444 recommended revision or acceptance and 172 rejection. Of 428 total citations, there were 122 peer reviewer self-citations (29%) and 306 citations to others' work (71%). Self-citations were more common in reviews recommending revision or acceptance (105 of 316 citations; 33%) versus rejection (17/112; 15%; pcitations with no rationale (26 of 122; 21%) was higher than for citations to others' work (15 of 306; 5%; pcitation in peer reviews is common and may reflect a combination of appropriate citation to research that should be cited in published articles and inappropriate citation intended to highlight the work of the peer reviewer. Providing instructions to peer reviewers about self-citation and asking them to indicate when and why they have self-cited may help to limit self-citation to appropriate, constructive recommendations.

Two diachronic citation windows are applied: 2006-07 and 2006-08. Web of Science (WoS) as well as Google Scholar (GS) are applied to observe the cite delay and citedness for the different document types published by DIIS...... for all document types. Statistical significant correlations were only found between WoS and GS and the two publication point systems in between, respectively. The study demonstrates how the nCPPI can be applied to institutions as evaluation tools supplementary to JCI in various combinations...

  17. Revisiting an open access monograph experiment: measuring citations and tweets 5 years later.

    Science.gov (United States)

    Snijder, Ronald

    An experiment run in 2009 could not assess whether making monographs available in open access enhanced scholarly impact. This paper revisits the experiment, drawing on additional citation data and tweets. It attempts to answer the following research question: does open access have a positive influence on the number of citations and tweets a monograph receives, taking into account the influence of scholarly field and language? The correlation between monograph citations and tweets is also investigated. The number of citations and tweets measured in 2014 reveal a slight open access advantage, but the influence of language or subject should also be taken into account. However, Twitter usage and citation behaviour hardly overlap.

    The quality and quantity of published research papers are important in both scientific and technology fields. Although there are several bibliometric studies based on citation analysis, very few have focused on research related to Traditional Chinese Medicine in China. The bibliometric method used in this study included the following focuses: publication outputs for each year, paper type, language of publication, distribution of internationally collaborative countries, sources of funding, authorization number, distribution of institutes regarding collaborative publications, research fields, distribution of outputs in journals, citation, data, and h-index. A total of 3809 papers published from 1995 to 2012 were extracted from the science citation index (SCI). The cumulative number of papers from all six universities is constantly increasing. The United States attained the dominant position regarding complementary and alternative medicine research. The Chinese Academy of Sciences was the greatest participator in collaborative efforts. Research field analysis showed that the research mainly focused on pharmacology pharmacy, chemistry, integrative complementary medicine, plant sciences, and biochemistry molecular biology. The Shanghai University of Chinese Medicine had the most citations. In recent years, in terms of SCI papers, the six Traditional Chinese Medicine universities studied here have made great advances in scientific research.

    2012-08-31

    We put under experimental scrutiny the preferential attachment model that is commonly accepted as a generating mechanism of the scale-free complex networks. To this end we chose a citation network of physics papers and traced the citation history of 40,195 papers published in one year. Contrary to common belief, we find that the citation dynamics of the individual papers follows the superlinear preferential attachment, with the exponent α=1.25-1.3. Moreover, we show that the citation process cannot be described as a memoryless Markov chain since there is a substantial correlation between the present and recent citation rates of a paper. Based on our findings we construct a stochastic growth model of the citation network, perform numerical simulations based on this model and achieve an excellent agreement with the measured citation distributions.

Keywords in English, Spanish, Italian and German, truncated terms (such as ‘bienn’, single letters (such as P, and numbers were combined to retrieve all possible citations. Additional filters to exclude citations to publications other than proceedings were applied to the P search results, which had accounted for 75% of the total results. The references remaining in the P search set were validated using Google Scholar and WorldCat. Finally, two random samples of 1,000 references were checked manually to determine the extent of false positives and false negatives in the results.Main Results – The study’s findings are presented for NSE and SSH separately, with 1.7% of NSE citations and 2.5% of SSH citations referring to conference proceedings. The total number of citations to proceedings has increased over the period 1980-2005, however, citations to proceedings in NSE and SSH as a proportion of all citations decreased during this time. A small increase in the average number of proceedings citations per paper was found for NSE and SSH. When this increase is compared to the overall increase in references per paper over this period, the share of proceedings citations per paper has decreased. Of all fields in NSE and SSH, only engineering has increased the proportion of proceedings citations, rising from 7% to 10% in the period studied. In 2005, the share of proceedings

    The Accreditation Council for Graduate Medical Education (ACGME) requires the graduate medical education committee and the designated institutional official to ensure that citations for noncompliance with the accreditation standards and institutional trends in citations are reviewed and corrected. To describe a citation tracking system (CTS) that uses Microsoft Office Access to efficiently catalogue, monitor, and document resolution of citations. The CTS was implemented in a sponsoring institution with oversight of 133 ACGME-accredited programs. The designated institutional official and the graduate medical education committee review all program letters of notification and enter citations into the CTS. A program-correction plan is required for each citation and is entered into the database. Open citations and action plans are reviewed by the graduate medical education committee and the designated institutional official on a quarterly basis, with decisions ranging from "closing" the citation to approving the action plan in process to requiring a new or modified action plan. Citation categories and subcategories are accessed on the ACGME website and entered into the CTS to identify trends. All 236 citations received since the 2006 Mayo School of Graduate Medical Education institutional site visit were entered into the CTS. On November 22, 2011, 26 of 236 citations (11%) were in active status with ongoing action plans, and 210 (89%) citations had been resolved and were closed. The CTS uses commercially available software to ensure citations are monitored and addressed and to simplify analysis of citation trends. The approach requires minimal staff time for data input and updates and can be performed without institutional information technology assistance.

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

    Science.gov (United States)

    2013-01-01

    Background Systematic reviews are important for informing clinical practice and health policy. The aim of this study was to examine the bibliometrics of systematic reviews and to determine the amount of variance in citations predicted by the journal impact factor (JIF) alone and combined with several other characteristics. Methods We conducted a bibliometric analysis of 1,261 systematic reviews published in 2008 and the citations to them in the Scopus database from 2008 to June 2012. Potential predictors of the citation impact of the reviews were examined using descriptive, univariate and multiple regression analysis. Results The mean number of citations per review over four years was 26.5 (SD ±29.9) or 6.6 citations per review per year. The mean JIF of the journals in which the reviews were published was 4.3 (SD ±4.2). We found that 17% of the reviews accounted for 50% of the total citations and 1.6% of the reviews were not cited. The number of authors was correlated with the number of citations (r = 0.215, P reviews published in the top quartile of JIFs (≥ 5.16) received citations in the bottom quartile (eight or fewer), whereas 9% of reviews published in the lowest JIF quartile (≤ 2.06) received citations in the top quartile (34 or more). Six percent of reviews in journals with no JIF were also in the first quartile of citations. Conclusions The JIF predicted over half of the variation in citations to the systematic reviews. However, the distribution of citations was markedly skewed. Some reviews in journals with low JIFs were well-cited and others in higher JIF journals received relatively few citations; hence the JIF did not accurately represent the number of citations to individual systematic reviews.

    This descriptive study evaluated behavioral and social science research on sport for 1993 through 2008, examined the characteristics of sport research, and identified mainstream issues appearing during these 16 years. Based on the Social Science Citation Index (SSCI) database from 1993 to 2008, 7,655 articles referring to sport or sports were available. The publication analyses showed that 13 core journals published the most articles in the behavioral sciences of sport. By analyzing all titles, author keywords, and KeyWords Plus, the results showed that physical education, athlete performance, and sports participation were the mainstream issues of sport research in the 16-year study period. The words adolescent, youth, and children frequently appeared, indicating that the emphasis of sport research focused on these participant groups. This bibliometric study reviewed global sports research in SSCI, and described certain patterns or trends in prior research on sport.

The Wilcoxon Signed Ranked tests demonstrated significant differences “in citation counts between all pairs (p Conclusion – The study does not confirm the authors’ hypothesis that differing scholarly coverage would result in different citation counts from the three databases. While there were significant differences in mean citation rates between all pairs of databases except for Google Scholar and Scopus in condensed matter physics for 2003, no one database performed better overall. Different databases performed better for different subjects, as well as for different years, especially Scopus, which only includes references starting in 1996. The results of this study suggest that the best citation database will depend on the years being searched as well as the subject area. For a complete picture of citation behaviour, the authors suggest all three be used.

  9. The Computational Infrastructure for Geodynamics: An Example of Software Curation and Citation in the Geodynamics Community

    2017-12-01

    Curation of software promotes discoverability and accessibility and works hand in hand with scholarly citation to ascribe value to, and provide recognition for software development. To meet this challenge, the Computational Infrastructure for Geodynamics (CIG) maintains a community repository built on custom and open tools to promote discovery, access, identification, credit, and provenance of research software for the geodynamics community. CIG (geodynamics.org) originated from recognition of the tremendous effort required to develop sound software and the need to reduce duplication of effort and to sustain community codes. CIG curates software across 6 domains and has developed and follows software best practices that include establishing test cases, documentation, and a citable publication for each software package. CIG software landing web pages provide access to current and past releases; many are also accessible through the CIG community repository on github. CIG has now developed abc - attribution builder for citation to enable software users to give credit to software developers. abc uses zenodo as an archive and as the mechanism to obtain a unique identifier (DOI) for scientific software. To assemble the metadata, we searched the software's documentation and research publications and then requested the primary developers to verify. In this process, we have learned that each development community approaches software attribution differently. The metadata gathered is based on guidelines established by groups such as FORCE11 and OntoSoft. The rollout of abc is gradual as developers are forward-looking, rarely willing to go back and archive prior releases in zenodo. Going forward all actively developed packages will utilize the zenodo and github integration to automate the archival process when a new release is issued. How to handle legacy software, multi-authored libraries, and assigning roles to software remain open issues.

    Self-citation is one of the main challenges in the evaluation of researchers' scientific output. This study aimed at comparing the institutional self-citation among the universities located in Northern Iran. This study was conducted as a scientometric study. Research population included all scientific productions of 16 Northern Iran Universities with at least 100 indexed documents indexed in the Web of Science (WoS) by 2 June 2015. The citation analysis section of WoS was used for data collection. SPSS was applied for data analysis. Study hypotheses were tested with two independent sample t-test and paired sample t-test. Producing 16,399 papers, northern Iran universities had 5.33% of contribution in Iran's scientific production. They received 84,058 citations with 17% and 12% of self-citations belonged to the non-medical and medical universities, respectively. Testing hypotheses revealed that increase in received citations significantly increases the rate of self-citation and increase in scientific production does not necessarily increase the rate of self-citation. The rate of self-citation in the studied universities was not relatively high. However, investigating into the factors affecting the rate of and motives for self-citation needs further research.

    To determine the prevalence of author self-citation in the field of otolaryngology. A retrospective review of bibliographic references in 5 otolaryngology journals. Five high-impact otolaryngology journals were reviewed over a 3-month period between January and March 2014 to identify the pattern of author self-citations. Data included study type, otolaryngology topic, authorship, total citations, author self-citations, and country of origin. Nearly two-thirds of articles contained at least 1 self-citation, with an average of 2.6 self-citations per article. Self-citations represented nearly 10% of total citations. Articles with at least 1 self-citation had more authors (5.8 vs 4.9, P otolaryngology literature is common and compares similarly to other medical specialties previously studied. Self-citation should not be considered inappropriate, as it is often done to expand on earlier research. Nevertheless, editors, researchers, and readers should be aware of this increasingly recognized phenomenon and its associated potential implications to the process of scientific inquiry. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    Predicting the fast-rising young researchers (the Academic Rising Stars) in the future provides useful guidance to the research community, e.g., offering competitive candidates to university for young faculty hiring as they are expected to have success academic careers. In this work, given a set of young researchers who have published the first first-author paper recently, we solve the problem of how to effectively predict the top k% researchers who achieve the highest citation increment in Δt years. We explore a series of factors that can drive an author to be fast-rising and design a novel pairwise citation increment ranking (PCIR) method that leverages those factors to predict the academic rising stars. Experimental results on the large ArnetMiner dataset with over 1.7 million authors demonstrate the effectiveness of PCIR. Specifically, it outperforms all given benchmark methods, with over 8% average improvement. Further analysis demonstrates that temporal features are the best indicators for rising stars prediction, while venue features are less relevant.

    Regional trade agreements are major international policy instruments that shape macro-economic and political systems. There is widespread debate as to whether and how these agreements pose risks to public health. Here we perform a comprehensive systematic review of quantitative studies of the health impact of trade and investment agreements. We identified studies from searches in PubMed, Web of Science, EMBASE, and Global Health Online. Research articles were eligible for inclusion if they were quantitative studies of the health impacts of trade and investment agreements or policy. We systematically reviewed study findings, evaluated quality using the Quality Assessment Tool from the Effective Public Health Practice Project, and performed network citation analysis to study disciplinary siloes. Seventeen quantitative studies met our inclusion criteria. There was consistent evidence that implementing trade agreements was associated with increased consumption of processed foods and sugar-sweetened beverages. Granting import licenses for patented drugs was associated with increased access to pharmaceuticals. Implementing trade agreements and associated policies was also correlated with higher cardiovascular disease incidence and higher Body Mass Index (BMI), whilst correlations with tobacco consumption, under-five mortality, maternal mortality, and life expectancy were inconclusive. Overall, the quality of studies is weak or moderately weak, and co-citation analysis revealed a relative isolation of public health from economics. We identified limitations in existing studies which preclude definitive conclusions of the health impacts of regional trade and investment agreements. Few address unobserved confounding, and many possible consequences and mechanisms linking trade and investment agreements to health remain poorly understood. Results from our co-citation analysis suggest scope for greater interdisciplinary collaboration. Notwithstanding these limitations, our

    About 3,000 new citations that are highly similar to citations in previously published manuscripts that appear each year in the biomedical literature (Medline) alone. This underscores the importance for the opportunity for editors and reviewers to have detection system to identify highly similar text in submitted manuscripts so that they can then review them for novelty. New software-based services, both commercial and free, provide this capability. The availability of such tools provides both a way to intercept suspect manuscripts and serve as a deterrent. Unfortunately, the capabilities of these services vary considerably, mainly as a consequence of the availability and completeness of the literature bases to which new queries are compared. Most of the commercial software has been designed for detection of plagiarism in high school and college papers; however, there is at least 1 fee-based service (CrossRef) and 1 free service (etblast.org), which are designed to target the needs of the biomedical publication industry. Information on these various services, examples of the type of operability and output, and things that need to be considered by publishers, editors, and reviewers before selecting and using these services is provided.

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

    Full Text Available An important incentive for scientists and researchers is the recognition and renown given to them in citations of their work. While citation rules are well developed for the use of papers published by others, very little rules are available for the citation of data made available by others. Increasingly, citation of the source of data is also requested in the context of socially relevant topics, such as climate change and its potential impacts. Providing means for data citation would be a strong incentive for data sharing. Georeferenced data are crucial for addressing many of the burning societal problems and to support related interdisciplinary research. The lack of a widely accepted method for giving credit to those who make their data freely available and for tracking the use of data throughout their life-cycle hampers data sharing. Furthermore, only clear and transparent data citation allows other scientists to obtain the identical data to replicate findings or for further research.

    In the scientometric, the main criterion in determining the scientific position and ranking of the scientific centers, particularly the universities, is the rate of scientific production and innovation, and in all participations in the global scientific development. One of the subjects more involved in repeatedly dealt with science and technology and effective on the improvement of health is medical science fields. In this research using scientometric and citation analysis, we studied the rate of scientific productions in the field of community medicine, which is the numbers of articles published and indexed in ISI database from 2000 to 2010. This study is scientometric using the survey and analytical citation. The study samples included all of the articles in the ISI database from 2000 to 2010. For the data collection, the advance method of searching was used at the ISI database. The ISI analyses software and descriptive statistics were used for data analysis. Results showed that among the five top universities in producing documents, Tehran University of Medical Sciences with 88 (22.22%) documents are allocated to the first rank of scientific products. M. Askarian with 36 (90/9%) published documents; most of the scientific outputs in Community medicine, in the international arena is the most active author in this field. In collaboration with other writers, Iranian departments of Community Medicine with 27 published articles have the greatest participation with scholars of English authors. In the process of scientific outputs, the results showed that the scientific process was in its lowest in the years 2000 to 2004, and while the department of Community medicine in 2009 allocated most of the production process to itself. Iranian Journal of Public Health and Saudi Medical Journal each of them had 16 articles which had most participation rate in the publishing of community medicine's department. On the type of carrier, community medicine's department by

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