Assessing the Citations of Articles on Intellectual Capital

This article is based on the intellectual capital (IC) literature and identifies factors that can influence the total number of citations from articles related to this subject. Seven hundred seventy-seven empirical articles about IC published between 1960 and 2016 from ISI Web of Science, Scopus, and Google Scholar were validated and used. Through logistic regression, the results reveal that: number of authors (p < 0.05); use of the triad of human, structural (organizational or process), and relational (social or customer) capital (p < 0.05); and the ISI impact factor (p < 0.001) are the factors with greatest influence on the total number of ISI citations from scientific articles on IC. The content analysis also provides insightful implications in the sense that articles with more citations use established conceptualizations of both human and social (or relational) capital, as well as addressing the still unexplored relationships between intellectual capital and organizations' economic or innovative performance.

Evaluation of scientific productions of Psychology Researchers in the ISI citation system during 2013-2017: Scientific Study

Evaluation of scientific productions of Psychology Researchers in the ISI citation system during 2013-2017: Scientific Study

Introduction to Volume 9, Issue 2 of topiCS.

This issue contains two very different and very interesting topics. We lead with the latest entry in our ongoing series, “Visions of Cognitive Science,” a paper by Robert Hamlin (University of Otago, New Zealand) titled, The gaze heuristic: Biography of an adaptively rational decision process. This is an unusual paper that must have been fun to write as it was exceedingly interesting and fun to read. Indeed, having read it straight through in one sitting, I immediately sent this to my friend and colleague Professor Gerd Gigerenzer to ask him to give it a fast “reality check” for me. His response was swift and his reaction was much the same as mine. We decided that not only was this a great paper for Topics in Cognitive Science but that we would write a short introduction that would frame the paper's contributions and help catch the eye of our busy colleagues with a somewhat whimsical title: A simple heuristic successfully used by humans, animals, and machines: The story of the RAF and Luftwaffe, hawks and ducks, dogs and frisbees, baseball outfielders and Sidewinder missiles – Oh My! After having been the Editor of topiCS for nine years, I am also happy that in this issue, I have published my own topic, Game-XP: Action Games as Experimental Paradigms for Cognitive Science. However, rather than saying more about that topic in this space, it seems more appropriate for me to refer you to the Topic Editor's introduction. In case you missed it …—a brief mention of topics appearing in recent issues of topiCS. A year ago in April 2016 (Volume 8, Issue 2), Topic Editor D. Kimbrough Oller published the collection of papers “New Frontiers in Language Evolution and Development.” This collection is already attracting attention with 10 ISI citations to date for the papers. Five of these citations are to the Lupyan and Bergen paper, “How Language Programs the Mind” with the other five citations evenly distributed among other papers. In our field, a year between when one paper is published and a second paper written, submitted, reviewed, revised, published, and indexed is not a long time. We commend this interesting, scholarly, and (at times) provocative collection of papers to our readers. topiCS encourages letters and commentaries on all topics, and proposals for new topics. Letters are typically 400–1,000 words (maximum: two published pages) and will be published without abstract or references (possibly 1–2 but usually none). Commentaries are often solicited by Topic Editors prior to the publication of their topic. However, commentaries after publication are also considered and should range between 1,000 and 2,000 words. Most commentaries would not have an abstract and would not include many references. The Executive Editor and the Senior Editorial Board (SEB) members are constantly searching for new and exciting topics for topiCS. Feel free to open communications with a short note to the Executive Editor ([email protected]) or an SEB member (SEB members are listed under the Editorial Board heading on the publisher's homepage for topiCS (http://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1756-8765/homepage/EditorialBoard.html).

First and second trimester serum tests with and without first trimester ultrasound tests for Down's syndrome screening.

Down's syndrome occurs when a person has three copies of chromosome 21 (or the specific area of chromosome 21 implicated in causing Down's syndrome) rather than two. It is the commonest congenital cause of mental disability. Non-invasive screening based on biochemical analysis of maternal serum or urine, or fetal ultrasound measurements, allows estimates of the risk of a pregnancy being affected and provides information to guide decisions about definitive testing. Before agreeing to screening tests, parents need to be fully informed about the risks, benefits and possible consequences of such a test. This includes subsequent choices for further tests they may face, and the implications of both false positive (i.e. invasive diagnostic testing, and the possibility that a miscarried fetus may be chromosomally normal) and false negative screening tests (i.e. a fetus with Down's syndrome will be missed). The decisions that may be faced by expectant parents inevitably engender a high level of anxiety at all stages of the screening process, and the outcomes of screening can be associated with considerable physical and psychological morbidity. No screening test can predict the severity of problems a person with Down's syndrome will have. To estimate and compare the accuracy of first and second trimester serum markers with and without first trimester ultrasound markers for the detection of Down's syndrome in the antenatal period, as combinations of markers. We conducted a sensitive and comprehensive literature search of MEDLINE (1980 to 25 August 2011), Embase (1980 to 25 August 2011), BIOSIS via EDINA (1985 to 25 August 2011), CINAHL via OVID (1982 to 25 August 2011), the Database of Abstracts of Reviews of Effectiveness (the Cochrane Library 25 August 2011), MEDION (25 August 2011), the Database of Systematic Reviews and Meta-Analyses in Laboratory Medicine (25 August 2011), the National Research Register (Archived 2007), and Health Services Research Projects in Progress database (25 August 2011). We did not apply a diagnostic test search filter. We did forward citation searching in ISI citation indices, Google Scholar and PubMed 'related articles'. We also searched reference lists of retrieved articles SELECTION CRITERIA: Studies evaluating tests of combining first and second trimester maternal serum markers in women up to 24 weeks of gestation for Down's syndrome, with or without first trimester ultrasound markers, compared with a reference standard, either chromosomal verification or macroscopic postnatal inspection. Data were extracted as test positive/test negative results for Down's and non-Down's pregnancies allowing estimation of detection rates (sensitivity) and false positive rates (1-specificity). We performed quality assessment according to QUADAS criteria. We used hierarchical summary ROC meta-analytical methods to analyse test performance and compare test accuracy. Analysis of studies allowing direct comparison between tests was undertaken. We investigated the impact of maternal age on test performance in subgroup analyses. Twenty-two studies (reported in 25 publications) involving 228,615 pregnancies (including 1067 with Down's syndrome) were included. Studies were generally high quality, although differential verification was common with invasive testing of only high risk pregnancies. Ten studies made direct comparisons between tests. Thirty-two different test combinations were evaluated formed from combinations of eight different tests and maternal age; first trimester nuchal translucency (NT) and the serum markers AFP, uE3, total hCG, free βhCG, Inhibin A, PAPP-A and ADAM 12. We looked at tests combining first and second trimester markers with or without ultrasound as complete tests, and we also examined stepwise and contingent strategies.Meta-analysis of the six most frequently evaluated test combinations showed that a test strategy involving maternal age and a combination of first trimester NT and PAPP-A, and second trimester total hCG, uE3, AFP and Inhibin A significantly outperformed other test combinations that involved only one serum marker or NT in the first trimester, detecting about nine out of every 10 Down's syndrome pregnancies at a 5% false positive rate. However, the evidence was limited in terms of the number of studies evaluating this strategy, and we therefore cannot recommend one single screening strategy. Tests involving first trimester ultrasound with first and second trimester serum markers in combination with maternal age are significantly better than those without ultrasound, or those evaluating first trimester ultrasound in combination with second trimester serum markers, without first trimester serum markers. We cannot make recommendations about a specific strategy on the basis of the small number of studies available.

The Glasgow Benefit Inventory: a systematic review of the use and value of an otorhinolaryngological generic patient-recorded outcome measure.

BackgroundThe Glasgow Benefit Inventory (GBI) is a validated, generic patient-recorded outcome measure widely used in otolaryngology to report change in quality of life post-intervention.Objectives of reviewTo date, no systematic review has made (i) a quality assessment of reporting of Glasgow Benefit Inventory outcomes; (ii) a comparison between Glasgow Benefit Inventory outcomes for different interventions and objectives; (iii) an evaluation of subscales in describing the area of benefit; (iv) commented on its value in clinical practice and research.Type of reviewSystematic review.Search strategy‘Glasgow Benefit Inventory’ and ‘GBI’ were used as keywords to search for published, unpublished and ongoing trials in PubMed, EMBASE, CINAHL and Google in addition to an ISI citation search for the original validating Glasgow Benefit Inventory paper between 1996 and January 2015.Evaluation methodPapers were assessed for study type and quality graded by a predesigned scale, by two authors independently. Papers with sufficient quality Glasgow Benefit Inventory data were identified for statistical comparisons. Papers with <50% follow-up were excluded.ResultsA total of 118 eligible papers were identified for inclusion. A national audit paper (n = 4325) showed that the Glasgow Benefit Inventory gave a range of scores across the specialty, being greater for surgical intervention than medical intervention or ‘reassurance’. Fourteen papers compared one form of surgery versus another form of surgery. In all but one study, there was no difference between the Glasgow Benefit Inventory scores (or of any other outcome). The most likely reason was lack of power. Two papers took an epidemiological approach and used the Glasgow Benefit Inventory scores to predict benefit. One was for tonsillectomy where duration of sore throat episodes and days with fever were identified on multivariate analysis to predict benefit albeit the precision was low. However, the traditional factor of number of episodes of sore throat was not predictive. The other was surgery for chronic rhinosinusitis where those with polyps on univariate analysis had greater benefit than those without. Forty-three papers had a response rate of >50% and gave sufficient Glasgow Benefit Inventory total and subscales for meta-analysis. For five of the 11 operation categories (vestibular schwannoma, tonsillectomy, cochlear implant, middle ear implant and stapes surgery) that were most likely to have a single clear clinical objective, score data had low-to-moderate heterogeneity. The value in the Glasgow Benefit Inventory having both positive and negative scores was shown by an overall negative score for the management of vestibular schwannoma. The other six operations gave considerable heterogeneity with rhinoplasty and septoplasty giving the greatest percentages (98% and 99%) most likely because of the considerable variations in patient selection. The data from these operations should not be used for comparative purposes. Five papers also reported the number of patients that had no or negative benefit, a potentially a more clinically useful outcome to report. Glasgow Benefit Inventory subscores for tonsillectomy were significantly different from ear surgery suggesting different areas of benefitConclusionsThe Glasgow Benefit Inventory has been shown to differentiate the benefit between surgical and medical otolaryngology interventions as well as ‘reassurance’. Reporting benefit as percentages with negative, no and positive benefit would enable better comparisons between different interventions with varying objectives and pathology. This could also allow easier evaluation of factors that predict benefit. Meta-analysis data are now available for comparison purposes for vestibular schwannoma, tonsillectomy, cochlear implant, middle ear implant and stapes surgery. Fuller report of the Glasgow Benefit Inventory outcomes for non-surgical otolaryngology interventions is encouraged.

Study of Scientific Production of Community Medicines and #8217; Department Indexed in ISI Citation Databases

Study of Scientific Production of Community Medicines' Department Indexed in ISI Citation Databases.

Background: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.Methods: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: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 presentation of 340(85.86%) articles had presented most of their scientific productions in the format of article, also in the field of community medicine outputs, article entitled: “Iron loading and erythrophagocytosis increase ferroportin 1 (FPN1) expression in J774 macrophages”(1) with 81 citations ranked first in cited articles. Subject areas of occupational health with 70 articles and subject areas of general medicine with 69 articles ranked the most active research areas in the Production of community medicine’s department.Conclusion:the obtained data showed the much growth of scientific production. The Tehran University of medical Sciences ranked the first in publishing articles in community medicine’s department and with most collaboration with community medicine department of England writers in this field and most writers will present their works in paper format.

Youth with Behavioral Health Disorders Aging Out of Foster Care: a Systematic Review and Implications for Policy, Research, and Practice.

This systematic review aimed to (1) identify and summarize empirical studies on youth with behavioral health disorders aging out of foster care and (2) address implications for behavioral health policy, research, and practice. We identified previous studies by searching PubMed, PsycINFO, EBSCO, and ISI Citation Indexes and obtaining references from key experts in the child welfare field. A total of 28 full articles published between 1991 and 2014 were reviewed and summarized into the key areas including systems of care, disability type, transition practice area, study methods, study sample, transition outcome measures, study analysis, and study findings. Considering how fast youth who have behavioral health disorders fall through the crack as they exit foster care, one cannot understate the importance of incorporating timely and appropriate transition planning and care coordination for youth who have behavioral health disorders aging out of foster care into the usual case management performed by behavioral health systems and service providers.

A systematic review of the use of an expertise-based randomised controlled trial design.

BackgroundUnder a conventional two-arm randomised trial design, participants are allocated to an intervention and participating health professionals are expected to deliver both interventions. However, health professionals often have differing levels of expertise in a skill-based interventions such as surgery or psychotherapy. An expertise-based approach to trial design, where health professionals only deliver an intervention in which they have expertise, has been proposed as an alternative. The aim of this project was to systematically review the use of an expertise-based trial design in the medical literature.MethodsWe carried out a comprehensive search of nine databases—AMED, BIOSIS, CENTRAL, CINAHL, Cochrane Methodology Register, EMBASE, MEDLINE, Science Citation Index, and PsycINFO—from 1966 to 2012 and performed citation searches using the ISI Citation Indexes and Scopus. Studies that used an expertise-based trial design were included. Two review authors independently screened the titles and abstracts and assessed full-text reports. Data were extracted and summarised on the study characteristics, general and expertise-specific study methodology, and conduct.ResultsIn total, 7476 titles and abstracts were identified, leading to 43 included studies (54 articles). The vast majority (88 %) used a pure expertise-based design; three (7 %) adopted a hybrid design, and two (5 %) used a design that was unclear. Most studies compared substantially different interventions (79 %). In many cases, key information relating to the expertise-based design was absent; only 12 (28 %) reported criteria for delivering both interventions. Most studies recruited the target sample size or very close to it (median of 101, interquartile range of 94 to 118), although the target was reported for only 40 % of studies. The proportion of participants who received the allocated intervention was high (92 %, interquartile range of 82 to 99 %).ConclusionsWhile use of an expertise-based trial design is growing, it remains uncommon. Reporting of study methodology and, particularly, expertise-related methodology was poor. Empirical evidence provided some support for purported benefits such as high levels of recruitment and compliance with allocation. An expertise-based trial design should be considered but its value seems context-specific, particularly when interventions differ substantially or interventions are typically delivered by different health professionals.Electronic supplementary materialThe online version of this article (doi:10.1186/s13063-015-0739-5) contains supplementary material, which is available to authorized users.

Erratum to: Proof over promise: towards a more inclusive ranking of Dutch academics in Economics &amp; Business

An unfortunate error occurred in the collection of ISI data for author Alfons Oude Lansink. This was caused by the fact that his articles in Science journals such as Poultry Science and Journal of Dairy Science were listed under a different author name format and hence were inadvertently excluded in his ISI article and citation count. Although this does not change the conclusions of our article, which are based on Google Scholar data, we offer our sincere apologies for our underreporting of this author’s ISI publication and citation record. In the results section, the paragraph that starts with ‘‘The high rank of Alfons Oude Lansink...’’ should read as ‘‘Alfons Oude Lansink (#8) published an even more impressive 53 articles between 2008 and 2012, many of which in journals with a high AIS, such as PLOS One, Biomass & Bioenergy and Phytopathology. However, although they deal with topics of high societal significance, none of these articles achieved high citation counts. As the articles were also normally co-authored with several co-authors, the CAY metric is fairly low.’’ In addition, Table 3 reported the wrong number of articles (80 instead of 111) and cites (622 instead of 841) for this author. The correct version of Table 3 is provided in this erratum.

Equality of Google Scholar with Web of Science Citations: Case of Malaysian Engineering Highly Cited Papers

This study uses citation analysis from two citation tracking databases, Google Scholar (GS) and ISI Web of Science, in order to test the correlation between them and examine the effect of the number of paper versions on citations. The data were retrieved from the Essential Science Indicators and Google Scholar for 101 highly cited papers from Malaysia in the field of engineering. An equation for estimating the citation in ISI based on Google scholar is offered. The results show a significant and positive relationship between both citation in Google Scholar and ISI Web of Science with the number of versions. This relationship is higher between versions and ISI citations (r = 0.395, p&lt;0.01) than between versions and Google Scholar citations (r = 0.315, p&lt;0.01). Free access to data provided by Google Scholar and the correlation to get ISI citation which is costly, allow more transparency in tenure reviews, funding agency and other science policy, to count citations and analyze scholars’ performance more precisely.

Citation analysis of the scientific publications of Britton Chance in ISI citation indexes

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.

Trk Family Neurotrophin Receptors and p75 Receptor. A Multiple Competing Hypothesis Case in the Nerve Growth Factor (NGF) History

In the area of Trk oncogene, this research has revealed the different competing hypotheses made at the time of its discovery. A conflict of interest arose within the group who identified it as the nerve growth factor receptor (NGF). An auxiliary assumption, on the cardinal importance of the low affinity p75 receptor, resulted in that the consistency of the group take patterns of competence. The level of provocation affected the joint effort. An environment reminds the denial that Stehelin was given by Varmus and Bishop, in the race for the Nobel Prize in Physiology or Medicine. Nowadays p75 receptor functions are described as “enigmatic”, and accepted that all the neurotrophins interact with two types of receptors: the specific to the ligands of the high-affinity Trk family of receptors and the low affinity p75 receptor (with structural similarities to the tumor necrosis factor and in liaison with the development of eye optical fiber). Against this background, papers concerning this subject and included in the ISI citation database are analysed, categorizing them through a system of descriptors, according to their original publication date. Complete time vectors are approximated by setting the analysis with a growth model based on Gompertz function. After the criteria used by authorities like Rita Levi-Montalcini, Luigi Cavalli-Sforza, Rodolfo Llinás and Victor McKunsick the selected material resulted in a database with 371 records. The data suggest the opportunity for historical sciences of a non-discrimination compliance test performed on multiple hypotheses.

Citation Impact of Open Access Medical Journals on Scholarly Communication: Web Citation Analysis

Considering the value and importance of Open Access (OA) journals as prime medium of scientific communication, this paper tried to assess the citations pattern of OA journals. This study aimed at to study the citation tracking of OA Journals using the Google Scholar Citations. And also intended to examine the correlation between ISI and Web citations in Medicine. It identify the characteristics of Web citing sources such as file format, hyperlinking, Internet domain, language and publication year in the discipline Neurology in 2007. The results show that 56% of the Google Scholar citations were from OA and the file format of the OA citing sources that targeting Neurology research papers, was mostly PDF format.

Risk of bias of randomized controlled trials published in orthopaedic journals

BackgroundThe purpose of this study was to assess the quality of methodology in orthopaedics-related randomized controlled trials (RCTs) published from January 2006 to December 2010 in the top orthopaedic journals based on impact scores from the Thompson ISI citation reports (2010).MethodsJournals included American Journal of Sports Medicine; Journal of Orthopaedic Research; Journal of Bone and Joint Surgery, American; Spine Journal; and Osteoarthritis and Cartilage. Each RCT was assessed on ten criteria (randomization method, allocation sequence concealment, participant blinding, outcome assessor blinding, outcome measurement, interventionist training, withdrawals, intent to treat analyses, clustering, and baseline characteristics) as having empirical evidence for biasing treatment effect estimates when not performed properly.ResultsA total of 232 RCTs met our inclusion criteria. The proportion of RCTs in published journals fell from 6% in 2006 to 4% in 2010. Forty-nine percent of the criteria were fulfilled across these journals, with 42% of the criteria not being amendable to assessment due to inadequate reporting. The results of our regression revealed that a more recent publication year was significantly associated with more fulfilled criteria (β = 0.171; CI = −0.00 to 0.342; p = 0.051).ConclusionIn summary, very few studies met all ten criteria. Thus, many of these studies likely have biased estimates of treatment effects. In addition, these journals had poor reporting of important methodological aspects.

MODELING CITATION DIFFUSION: INNOVATION MANAGEMENT LITERATURE

Citation patterns are important to understanding the spread of technological ideas as science is essentially a cumulative activity. One feature only now being appreciated is the obsolescence or ageing patterns in citations and the insights their study can bring. There have been a number of studies examining, predicting, modeling and plotting citation delays, ageing and the publication cycle. These normally apply lognormal, log-logistic and Weibull distributions to scientific papers. This paper adds to this body of work by examining a set of 18 other distributions, and tests their predictive power on a new data set based on 10 years of ISI Citation data for 10 innovation centered journals. The resulting grouping of journals appears to be a useful proxy for academic-practitioner involvement and warrants further investigation. The finding that the three-parameter Inverse Gaussian provides the best fit to the data extends the understanding of this process. As well as allowing the classification of literature, this improved representation of citation obsolescence will allow us to predict earlier and more precisely those scientific ideas which are generating noteworthy attention or may be suitable for early exploitation.
