    Full Text Available Many diseases in Africa can be prevented with appropriate public health interventions. This study aimed to assess the bibliometric characteristics of public health related research articles published by researchers in African institutions from 1991 to 2005. Data used in this study were obtained from the online version of the ISI Web of Science: Science Citation Index Expanded (SCI-Expanded. Articles published between 1991 and 2005 that had the phrase ‘public health’ in the title, author keywords or abstract, and had at least one author whose contact address was in an African country, were selected for analysis. The annual number of public health related articles published by African researchers significantly increased from 28 articles in 1991 to 135 articles in 2005, a 382% increase. International collaboration also increased: from 45% of articles having international collaborators during 1991–1995, to 52% during1996–2000, and to 67% during 2001–2005. Collaborations were mostly with European and North American countries. Keywords, subject categories and collaboration patterns of articles varied across regions, reflecting differences in needs and collaboration networks. Public health related research output, as well as international collaborations, have been increasing in Africa. Regional variation observed in this study may assist policymakers to facilitate the advancement of public health research in different regions of Africa, and could be useful for international organisations in identifying needs and to allocate research funding. Future bibliometric analyses of articles published by African researchers, can consider conducting regional comparisons using standardised methods, as well as describing the overall patterns, in order to provide a more comprehensive view of their bibliometric characteristics.

    Full Text Available Abstract Background Several bibliometric studies have been published on AIDS. The findings obtained from these studies have provided a general picture of the history and growth of AIDS literature. However, factors related to variation in HIV research productivity in sub-Saharan Africa have not been examined. Therefore, this study aims to fill some of the gap in existing research to provide insights into factors associated with HIV research productivity in sub-Saharan Africa. Methods A bibliometric analysis regarding sub-Saharan Africa HIV/AIDS research was conducted in the PubMed database for the period of 1981 to 2009. The numbers of HIV research articles indexed in PubMed was used as surrogate for total HIV research productivity. Series of univariable and multivariable negative binomial regression models were used to explore factors associated with variation in HIV research productivity in sub-Saharan Africa. Results First authors from South Africa, Uganda and Kenya contributed almost half of the total number of HIV articles indexed in PubMed between 1981 and 2009. Uganda, Zimbabwe and Malawi had better records when the total production was adjusted for gross domestic product (GDP. Comoros, the Gambia and Guinea-Bissau were the most productive countries when the total products were normalized by number of people with HIV. There were strong positive and statistically significant correlation between countries number of indexed journal (Pearson correlation r = 0.77, p = .001, number of higher institutions (r = 0.60, p = .001, number of physicians (r = 0.83, p = .001 and absolute numbers of HIV articles. Conclusions HIV research productivity in Africa is highly skewed. To increase HIV research output, total expenditure on health (% of GDP, private expenditure on health, and adult literacy rate may be important factors to address.

    Bibliometric parameters have become an important part of modern assessment of academic productivity. These parameters exist for the purpose of evaluating authors (publication count, citation count, h-index, m-quotient, hc-index, e-index, g-index, i-10 [i-n] index) and journals (impact factor, Eigenfactor, article influence score, SCImago journal rank, source-normalized impact per paper). Although in recent years there has been a proliferation of bibliometric parameters, the true meaning and appropriate use of these parameters is generally not well understood. Effective use of existing and emerging bibliometric tools can aid in assessment of academic productivity, including readiness for promotions and other awards. However, if not properly understood, the data can be misinterpreted and may be subject to manipulation. Familiarity with bibliometric parameters will aid in their effective implementation in the review of authors-whether individuals or groups-and journals, as well as their possible use in the promotions review process, maximizing the effectiveness of bibliometric analysis.

    Full Text Available The present study aims to introduce and analyze bibliometric application within Web and also to expounds on the status of link analysis in order to point out its application with respect to the existing web-based information sources. Findings indicate that bibliometrics could have required application in the area of digital resources available through Net. Link analysis is a process by which one could make statistical analysis of correlation between hyperlinks and therefore understand the accuracy, veracity and efficacy of citations within a digital document. Link analysis, in effect, is counted as a part of information ranking algorithm within the web environment. The number, linkage and quality of given links to a website are of utmost importance for ranking/status in the Web. The tools applied in this topic include, page ranking strategy, link analysis algorithm, latent semantic indexing and the classical input-output model. The present study analyzes Big Web and Small Web link analysis and explains the means for utilizing web charts in order to better understand the link analysis process.

  8. A Bibliometric Analysis of Climate Engineering Research

    Belter, C. W.; Seidel, D. J.

    2013-12-01

    The past five years have seen a dramatic increase in the number of media and scientific publications on the topic of climate engineering, or geoengineering, and some scientists are increasingly calling for more research on climate engineering as a possible supplement to climate change mitigation and adaptation strategies. In this context, understanding the current state of climate engineering research can help inform policy discussions and guide future research directions. Bibliometric analysis - the quantitative analysis of publications - is particularly applicable to fields with large bodies of literature that are difficult to summarize by traditional review methods. The multidisciplinary nature of the published literature on climate engineering makes it an ideal candidate for bibliometric analysis. Publications on climate engineering are found to be relatively recent (more than half of all articles during 1988-2011 were published since 2008), include a higher than average percentage of non-research articles (30% compared with 8-15% in related scientific disciplines), and be predominately produced by countries located in the Northern Hemisphere and speaking English. The majority of this literature focuses on land-based methods of carbon sequestration, ocean iron fertilization, and solar radiation management and is produced with little collaboration among research groups. This study provides a summary of existing publications on climate engineering, a perspective on the scientific underpinnings of the global dialogue on climate engineering, and a baseline for quantitatively monitoring the development of climate engineering research in the future.

    We present a detailed bibliometric analysis of the scientific contributions of Manuel Cardona, who represents an interesting example of a renowned scientist with a long and fruitful career. His publications provide an appropriate basis to apply various bibliometric techniques to measure the impact of his scientific achievements. For this purpose, we have taken into account his full publication record, the institutions of all his coauthors, the journals where his papers have been published, and the citations of his papers as a measure of their impact. We have analyzed in more detail some of his most important publications, which appeared as journal papers and book contributions. Additionally, we have broken down the complete ensemble of the citing papers with respect to the countries of authors, the journals, and the subject areas. The analysis performed in this study also makes use of the Hirsch index as one of the most recognized bibliometric indicators which has rapidly captured the field of research evaluation. Finally, we have established the citation historiogram based on the most highly-cited papers to visualize their citation network. (Copyright copyright 2011 WILEY-VCH Verlag GmbH and Co.

    Bibliometric indicators are used to assess research performance. The goal of this study was to explore publication output to construct a picture of orthopedics that may be beneficial to researchers and orthopedic specialists. All orthopedics articles published in 61 journals from 2000 to 2011 were retrieved from the Science Citation Index Expanded database. The numbers of articles, citations, authors, institutions, and journals were analyzed and subjected to quantitative and qualitative comparisons. The number of published orthopedics articles increased between 2000 and 2011. Articles published by authors from the United States always ranked first in number, although the United States' share is decreasing in the world literature. Authors from the United States published the most-cited articles and the most articles in journals with top-10 impact factors; moreover, the United States also had the greatest share of experts and highly ranked institutions. The United Kingdom, Germany, and Japan were always within the world's top 4 in terms of numbers of articles and citations. The shares of Germany, South Korea, and China among total orthopedics articles increased, especially that of China. In 2011, China ranked the fifth in the world, with its world share increasing from 0.64% in 2000 to 5.05% in 2011. However, China lags behind in average citations per article, top research institutions, and most prolific authors. According to the total citations per article, the University of Pittsburgh, Harvard University, and the Hospital for Special Surgery were the most prolific institutions.

    Full Text Available This paper used a bibliometric research to compare and draw an overview of scientific production on forensic Accounting area, published in Brazilian journals in the period between 2005 and 2014 regarding the number of publications, characteristics of the authors, published topics, methodologies and its subclasses and and journals that publish in the area. It was collected and analyzed 48 articles the information as variation of year publication, subjects treated by, authors and their characteristics, Qualis classification, methodology, methodological nature applied, description of the empirical method and journals that have published articles in the area. Descriptive statistics were used to analyze the data. As a result it was found that the main subjects considered are related to the "work of the expert accountant", "expert opinion" and expertise within the context of judicial proceedings. Regarding the authors the vast majority produce only one article in the area over the 10 years examined, and these authors, 64,58% were male. The Qualis extract of the articles is located between C and B1, indicating that the publications fail to achieve high standards of academic quality. On the methodology it was found that 91.67% are empirical research, of these 78% ranked in quantitative or qualitative and 83% are publications opting for descriptive techniques. Regarding the journals, it was found that 50% have only one publication on "forensic accounting", indicating that it is not repeated exposure, as the number of publications ranging from two to five in the other 50% of journals. It is concluded that scientific research in forensic accounting area are still relatively embryonic, lacking certain softening related to the subjects, number of publications and quality of intellectual production.

    Bibliometric studies, which involve the use of statistical methods, are increasingly being used for research assessment. A bibliometric analysis was conducted to evaluate the publication pattern of methaemoglobinaemia research output at the global level based on the Scopus database. We analysed selected documents with "methemoglobinemia", or "methaemoglobinaemia" as a part of the title and reported the following parameters: trends of publication output, country of publication, journal pattern, collaborative measures, citations pattern, and institute productivity. A total of 1770 articles were published worldwide. The time trend for the number of articles showed an increase after 2000. The highest number of articles related to methaemoglobinaemia was from the USA (24.8 %), followed distantly by the UK (4.5 %), India (3.7 %), and France (3.7 %). No data related to methaemoglobinaemia were published from 152 countries. The total number of citations at the date of data collection was 10,080, with an average of 5.7 citations per document. The USA and UK had the highest h-index of 31 and 14, respectively, and six countries had an h-index of 9-14. It is notable that Canada was ranked eighth in the number of publications but fourth in h-index and India was ranked third in the number of publications but eighth in h-index. Furthermore, Canada produced the most internationally collaborated papers out of the total number of publications for each country (16.1 %), followed by the UK (13.9 %). This bibliometric analysis provides data contributing to a better understanding of the methaemoglobinaemia research field. The number of publications on methaemoglobinaemia increased significantly after 2000. The USA was the most productive country as measured by total publications. The USA and UK achieved the highest h-index in the field of methaemoglobinaemia research, signifying a higher quality of research than other countries.

The impact in the different groupings is judged by means of citation analysis using normalized data and an almost linear increase can be observed from 1994 onwards in the non-ILS category. The implication for the dissemination and use of the bibliometric methods in the different contexts is discussed. A keyword analysis identifies the most popular subjects covered by bibliometric analysis, and multidisciplinary articles are shown to have the highest impact. A noticeable shift is observed in those countries which contribute to the pool of bibliometric analysis, as well as a self-perpetuating effect in giving and taking references.

    Full Text Available Introduction: Integrated care could not only fix up fragmented health care but also improve the continuity of care and the quality of life. Despite the volume and variety of publications, little is known about how ‘integrated care’ has developed. There is a need for a systematic bibliometric analysis on studying the important features of the integrated care literature.Aim: To investigate the growth pattern, core journals and jurisdictions and identify the key research domains of integrated care.Methods: We searched Medline/PubMed using the search strategy ‘(delivery of health care, integrated [MeSH Terms] OR integrated care [Title/Abstract]’ without time and language limits. Second, we extracted the publishing year, journals, jurisdictions and keywords of the retrieved articles. Finally, descriptive statistical analysis by the Bibliographic Item Co-occurrence Matrix Builder and hierarchical clustering by SPSS were used.Results: As many as 9090 articles were retrieved. Results included: (1 the cumulative numbers of the publications on integrated care rose perpendicularly after 1993; (2 all documents were recorded by 1646 kinds of journals. There were 28 core journals; (3 the USA is the predominant publishing country; and (4 there are six key domains including: the definition/models of integrated care, interdisciplinary patient care team, disease management for chronically ill patients, types of health care organizations and policy, information system integration and legislation/jurisprudence.Discussion and conclusion: Integrated care literature has been most evident in developed countries. International Journal of Integrated Care is highly recommended in this research area. The bibliometric analysis and identification of publication hotspots provides researchers and practitioners with core target journals, as well as an overview of the field for further research in integrated care.

    2011-10-01

    Full Text Available In this paper, we analyse the evolution of social representations theory (SRT over time, languages, and journals by comparing it with the evolution of social identity theory (SIT. Additionally, we perform a lexical analysis of abstracts on SRT and discuss the changes of topics over time and languages. While SRT is less represented in mainstream journals of social psychology than SIT, it is more widely distributed across linguistic areas, as shown by the relative frequency of different languages. Two major research domains often associated with SRT are health issues and intergroup dynamics. Papers concentrating on SRT as a theoretical approach are more recent and primarily written in English, while French-language papers focus less on theoretical aspects. While SRT is diverse and recognized in social psychology, it is not as widely known as other social psychological theories (e.g., SIT. We conclude with thoughts on how to promote wider integration of SRT with mainstream social psychology.

    Many studies in information science have looked at the growth of science. In this study, we re-examine the question of the growth of science. To do this we (i) use current data up to publication year 2012 and (ii) analyse it across all disciplines and also separately for the natural sciences and for the medical and health sciences. Furthermore, the data are analysed with an advanced statistical technique (segmented regression analysis) which can identify specific segments with similar growth rates in the history of science. The study is based on two different sets of bibliometric data: (1) The number of publications held as source items in the Web of Science (WoS, Thomson Reuters) per publication year and (2) the number of cited references in the publications of the source items per cited reference year. We have looked at the rate at which science has grown since the mid-1600s. In our analysis we identified three growth phases in the development of science, which each led to growth rates tripling in compariso...

    Full Text Available Introduction: Since Tim Berners-Lee coined the term Linked Data in 2006, many studies have emerged based on this initiative. Whether in the form of information access initiatives, whether in applications based on this data type, the interest in this new way to publish and consume information on the Web is increasingly in focus. Objective: In this paper, we present a bibliometric review with the aim of contributing to a better understanding and clarification of concepts and terms associated with the area of Linked Data. Methodology: We have used the Web of Science (WoS, Scopus, EBSCO and IEEE scientific databases, in order to find the existing studies about Linked Data until October 2012. Results: We have mapped 148 scientific papers that address the above issue, written by 409 authors from 160 institutions from 30 different countries. Through the analysis of the articles, it was found that researches about Linked Data are concentrated in a small authors group, suggesting future research opportunities. Conclusions: Synthesizing the information related to the scientific publications in a given area allows building a theoretical background that supports the development of future researches.

    Full Text Available Objective: Human pluripotent stem cells are self-renewing cells with the ability to differentiate into a variety of cells and are viewed to have great potential in the field of regenerative medicine. Research in pluripotent stem cells holds great promise for patient specific therapy in various diseases. In this study, pluripotent stem cell articles published from 1991 to 2012 were screened and retrieved from Science Citation Index Expanded (SCI-EXPANDED. Materials and Methods: In this retrospective study, the publication trend, citation trends for top articles, distributions of journals and Web of Science categories were analyzed. Five bibliometric indicators including total articles, independent articles, collaborative articles, first author articles, and corresponding author articles were applied to compare publications between countries and institutions. Results: The impact of top articles changed from year to year. Top cited articles in previous publication years were not the same as recent years. "Induced pluripotent stem cell (s" and "embryonic stem cell (s" were the most used author keywords in pluripotent stem cell research. In addition, the winner of the Nobel Prize in physiology or medicine in 2012, Prof. Shinya Yamanaka, published four of the top ten most frequently cited articles. Conclusion: The comprehensive analysis of highly cited articles in the stem cell field could identify milestones and important contributors, giving a historic perspective on scientific progress.

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

    2016-01-01

    The study of scientific production is a good indicator of the progress in research and knowledge generation. Bibliometrics is a scientific discipline that uses a set of indicators to quantitatively express the bibliographic characteristics of scientific publications. The scientific literature on the epidemiology of intestinal parasites in Argentina is scattered in numerous sources, hindering access and visibility to the scientific community. Our purpose was to perform a quantitative, bibliometric study of the scientific literature on intestinal parasites in humans in Argentina published in the period 1985-2014. This bibliometric analysis showed an increase in the number of articles on intestinal parasites in humans in Argentina published over the past 30 years. Those articles showed a collaboration index similar to that of the literature, with a high index of institutionality for national institutions and a very low one for international collaboration. The original articles were published in scientific journals in the American Continent, Europe and Asia. The use of bibliometric indicators can provide a solid tool for the diagnosis and survey of the research on epidemiology of intestinal parasites and contributes to the dissemination and visibility of information on the scientific production developed in Argentina.

    Clancy, Rachel B.; Herring, Matthew P.; Campbell, Mark J.

    2017-01-01

    Motivation is widely-researched, in both sport psychology and other fields. As rigorous measurement is essential to understanding this latent construct, a critical appraisal of measurement instruments is needed. Thus, the purpose of this review was to evaluate the six most highly cited motivation measures in sport. Peer-reviewed articles published prior to August 2016 were searched to identify the six most highly cited motivation questionnaires in sport: Sport Motivation Scale (SMS), Intrinsic Motivation Inventory (IMI), Situational Motivational Scale (SIMS), Perceptions of Success Questionnaire (POSQ), Behavioural Regulation in Sport Questionnaire (BRSQ), and Task and Ego Orientation in Sport Questionnaire (TEOSQ). The questionnaires were then evaluated and discussed in four sections: Development, Reliability, Correlates, and Summary. Bibliometric data were also calculated (average weighted impact factor) and assessed (e.g., citations per year) to evaluate the impact of the use of each questionnaire. Despite some variance in their psychometric properties, conceptualization, structure, and utility, the six questionnaires are psychometrically strong instruments for quantifying motivation that are widely supported in the literature. Bibliometric analyses suggested that the IMI ranks first and the SMS ranks sixth according to the average weighted impact factors of their original publications. Consideration of each questionnaire's psychometric strengths/limitations, and conceptualization of motivation in the context of specific research questions should guide researchers in selecting the most appropriate instrument to measure motivation in sport. The average weighted impact factor of each questionnaire is a useful value to consider as well. With these points in mind, recommendations are provided. PMID:28337165

    Citation analysis is an established bibliometric method which catalogues papers according to the number of times they have been referenced. It is believed that the total number of citations an article receives reflects its importance among its peers. Never before has a bibliometric analysis been performed in the area of Cleft Lip and Palate. Our citation analysis creates a comprehensive list of the 50 most influential papers in this field. Journals specializing in Cleft Palate, Craniofacial, Plastic Surgery, Maxillofacial Surgery, Aesthetics and Radiology were searched to establish which articles most enriched the specialty over the past 70 years. The results show an interesting collection of papers which reveal developing trends in surgical techniques. These landmark papers mould and influence management and decision-making today.

    2014-03-01

    Full Text Available Introduction: There has been a noticeable increase in experimental use and therapies based on stem cells over recent years. Nevertheless, there is a lack of information about this progress in the dental field, which makes it difficult to trace development and design policies. The purpose of this study, as a first approach to the subject, is to determine a bibliometric profile for the investigation related to bioengineering of dental tissue at a worldwide scale, based on the MEDLINE database, for the period 2000-2011. Methodology: A bibliometric study was carried out. Every article indexed in the MEDLINE database and associated with the terms “stem cells” and “tooth regeneration” for the period 2000-2011 was included. The analyzed variables were publishing date, country of origin, language and publication type (original or review, journal, author, associated university and tissue source (human or animal. Results: For the entire period included in the study, 257 articles were found. Of these, 149 corresponded to original Works published in English; 5 in other languages; 92 comprised literature reviews in English, 9 in other languages and 2 publications were included in the “others” category. The countries with the highest research productivity were the United States (24.51%, Japan (20.62% and China (17.90%, while Brazil (3.9% was the only Latin-American country found in the list. Animal tissues were used in 59.09% of them. The most productive authors were Ueda M (17 and Jin Y (11, whereas Fourth Military University (13, University of Tokyo (12 and Capital Medical University (10 had the largest number of publications. Conclusion: The United States, Japan and China concentrate about two thirds of the production. Latin-America was represented only by Brazil.

    2013-09-01

    Full Text Available Modern technology is increasingly complex and demands an ever-widening range of knowledge and skills. No single country will possess all the knowledge and skills required for addressing global issues such as climate change. Technology collaboration between leading countries is important to promptly and efficiently address the problem. Previous studies have shown that a high level of collaboration is correlated with high paper productivity. This paper first aims to use objective data and create maps that enable us to see both the distribution of worldwide research competency and the relationship of international collaboration in clean energy research. In the international research network of wind power and solar cell, 4,189 institutions located in 121 countries and 6,600 institutions located in 125 countries are included respectively. This paper discusses various factors that would have an impact on research capability and support strong international relationships. With respect to research capability, governmental policies, stability of governmental commitment, natural conditions and historical and institutional differences have a significant impact on it. For research collaborations, factors such as geographical proximity, international science and technology policy, and developmental stage of technology have been brought to attention. This study demonstrates that bibliometrics is a methodology that is capable of providing a knowledge base that is useful in the development of the international science and technology policy and technological management strategy.

    In this article, the proceedings of the International Conferences on Defects in Semiconductors (ICDS) have been analyzed by bibliometric methods. The papers of these conferences have been published as articles in regular journals or special proceedings journals and in books with diverse publishers. The conference name/title changed several times. Many of the proceedings did not appear in the so-called “source journals” covered by the Thomson/ISI citation databases, in particular by the Science Citation Index (SCI). But the number of citations within these source journals can be determined using the Cited Reference Search mode under the Web of Science (WoS) and the SCI offered by the host STN International. The search functions of both systems were needed to select the papers published as different document types and to cover the full time span of the series. The most cited ICDS papers were identified, and the overall numbers of citations as well as the time-dependent impact of these papers, of single conferences, and of the complete series, was established. The complete of citing papers was analyzed with respect to the countries of the citing authors, the citing journals, and the ISI subject categories.

    In this work we analyse the evolution of the vulnerability concept in the research streams of climate change adaptation (CCA) and disaster risk reduction (DRR). We combine a traditional literature review with data mining procedures applied to bibliographic databases to reconstruct the history of the concept within various research topics, showing its evolution and convergences over time. To do that, we integrate different methods combining machine learning algorithms with network and cluster analyses to examine a set of 3757 articles, analysing their distinctive features and similarities on the basis of their contents as well as co-authorships. Bibliometric analyses enable the identification of different communities of articles, pinpointing key papers and authors, while literature review makes it possible to assess the concept of vulnerability evolved within and beyond research communities and scientific networks. Moreover, this work examines the role played by documents published by UN institutions (UNDRO, UNISDR, IPCC) in contributing to the evolution of vulnerability and related concepts. Results show that signs of convergence are evident between the two research streams, and that the IPCC reports have played a major role in proposing solutions for unifying definitions of vulnerability. We observe that the phases of preparation of the IPCC reports are very rich in methodological and terminological developments, while after publication, the literature shows evident signs of propagation of the proposed concepts. The DRR research stream developed before the research stream on CCA, but the latter flourished rapidly and became much larger in terms of number of publications. Nevertheless, in terms of contents, adaptation studies and the IPCC have shown increasing adoption of the concepts developed within the disaster research stream, in particular with regard to the interpretation of vulnerability as one of the dimensions of risk.

    Full Text Available In this article, we conducted the evaluation of artificial intelligence research from 1990–2014 by using bibliometric analysis. We introduced spatial analysis and social network analysis as geographic information retrieval methods for spatially-explicit bibliometric analysis. This study is based on the analysis of data obtained from database of the Science Citation Index Expanded (SCI-Expanded and Conference Proceedings Citation Index-Science (CPCI-S. Our results revealed scientific outputs, subject categories and main journals, author productivity and geographic distribution, international productivity and collaboration, and hot issues and research trends. The growth of article outputs in artificial intelligence research has exploded since the 1990s, along with increasing collaboration, reference, and citations. Computer science and engineering were the most frequently-used subject categories in artificial intelligence studies. The top twenty productive authors are distributed in countries with a high investment of research and development. The United States has the highest number of top research institutions in artificial intelligence, producing most single-country and collaborative articles. Although there is more and more collaboration among institutions, cooperation, especially international ones, are not highly prevalent in artificial intelligence research as expected. The keyword analysis revealed interesting research preferences, confirmed that methods, models, and application are in the central position of artificial intelligence. Further, we found interesting related keywords with high co-occurrence frequencies, which have helped identify new models and application areas in recent years. Bibliometric analysis results from our study will greatly facilitate the understanding of the progress and trends in artificial intelligence, in particular, for those researchers interested in domain-specific AI-driven problem-solving.

    Bibliometric analysis is the application of statistical methods to analyze quantitative data about scientific publications. It can evaluate research performance, author productivity, and manuscript impact. To the best of our knowledge, no bibliometric analysis has focused on cardiac computed tomography (CT). The purpose of this paper was to compile a list of the 100 most-cited articles related to cardiac CT literature using Scopus and Web of Science (WOS). A list of the 100 most-cited articles was compiled by order of citation frequency, as well a list of the top 10 most-cited guideline and review articles and the 20 most-cited articles of the years 2014-2015. The database of 100 most-cited articles was analyzed to identify characteristics of highly cited publications. For each manuscript, the number of authors, study design, size of patient cohort and departmental affiliations were cataloged. The 100 most-cited articles were published from 1990 to 2012, with the majority (53) published between 2005 and 2009. The total number of citations varied from 3354 to 196, and the number of citations per year varied from 9.5 to 129.0 with a median and mean of 30.9 and 38.7, respectively. The majority of publications had a study patients sample size of 200 patients or less. The USA and Germany were the nations with the highest number of frequently cited publications. This bibliometric analysis provides insights on the most-cited articles published on the subject of cardiac CT and calcium volume, thus helping to characterize the field and guide future research.

    Full Text Available This paper deals with a bibliometric analysis of journal Kemija u industriji for the period 2000–2009. The results of the analysis show that the journal is still dealing with the problem of publishing scientific papers, which was also detected in a previous similar analysis (M. Jokia et al. (2002. Furthermore, in 82.1 % of categorized papers at least one author is from Croatia, while in 88.4 % at least one author is from neighboring countries (Croatia and other ex-Yugoslavia countries. This data reveals the strong national and regional orientation of the journal, which can be related with the language of publishing (mostly Croatian – 76.4 %, as well as with one of the basic functions of the journal according to its mission, which is to develop and improve chemistry and engineering terminology and nomenclature in the Croatian language. Journal citation analysis is based on the citation data gathered from the bibliographic and citation databases Scopus and Web of Science (WoS. Still, according to the specific bibliometric journal indicators(Impact Factor (IF, SCImago Journal Rank (SJR and Source Normalized Impact per Paper (SNIP, the analysis shows that Kemija u industriji could find its place among other related world journals.

  10. Looking for landmarks: the role of expert review and bibliometric analysis in evaluating scientific publication outputs.

    Directory of Open Access Journals (Sweden)

    Liz Allen

    Full Text Available OBJECTIVE: To compare expert assessment with bibliometric indicators as tools to assess the quality and importance of scientific research papers. METHODS AND MATERIALS: Shortly after their publication in 2005, the quality and importance of a cohort of nearly 700 Wellcome Trust (WT associated research papers were assessed by expert reviewers; each paper was reviewed by two WT expert reviewers. After 3 years, we compared this initial assessment with other measures of paper impact. RESULTS: Shortly after publication, 62 (9% of the 687 research papers were determined to describe at least a 'major addition to knowledge' -6 were thought to be 'landmark' papers. At an aggregate level, after 3 years, there was a strong positive association between expert assessment and impact as measured by number of citations and F1000 rating. However, there were some important exceptions indicating that bibliometric measures may not be sufficient in isolation as measures of research quality and importance, and especially not for assessing single papers or small groups of research publications. CONCLUSION: When attempting to assess the quality and importance of research papers, we found that sole reliance on bibliometric indicators would have led us to miss papers containing important results as judged by expert review. In particular, some papers that were highly rated by experts were not highly cited during the first three years after publication. Tools that link expert peer reviews of research paper quality and importance to more quantitative indicators, such as citation analysis would be valuable additions to the field of research assessment and evaluation.

    The research trends on stent for blood arteries are reviewed by bibliometric analysis using 7,790 journal articles published from 1986 to 2013 of the Web of Science database. The bibliometric indicators are applied to analyze the journal article data, which are simple number of publications for selecting key players, citation indicators for measuring qualitative research performance, collaboration indicators for figuring out the degree of international collaboration and keyword mapping for identifying the research trends. The studies of stent for blood arteries are investigated on the basis of the analysis by countries, institutions and topic changing. The leading countries and institutions published many high-quality journal articles with strong international collaboration. In this report, the current status and future of research trends are clearly revealed from the periodic topic changing analysis. The keywords such as 'drug eluting stent', 'stent coated with new polymers' and 'drug delivery systems' have come into the recent stent-related research, which means lots of efforts are under way to overcome the present limitations of the research.

    Full Text Available Influenza virus vaccine (IVV is a promising research domain that is closely related to global health matters, which has been acknowledged not only by scientists and technology developers, but also by policy-makers. Meanwhile, patents encompass valuable technological information and reflect the latest technological inventions as well as the innovative capability of a nation. However, little research has examined this up-and-coming research field using patent bibliometric method. Thus, this paper (a designs the technology classification system and search strategy for the identification of IVV; and (b presents a longitudinal analysis of the global IVV development based on the European Patent Office (EPO patents. Bibliometric analysis is used to rank countries, institutions, inventors and technology subfields contributing to IVV technical progress. The results show that the global trends of IVV are a multi-developing feature of variety but an uneven technical resource distribution. Although the synthetic peptide vaccine is a comparatively young field, it already demonstrates the powerful vitality and the enormous development space. With the worldwide competition increasing, all nations especially China should be looking to increase devotion, enhance capability and regard effectiveness of technological innovation.

    Guler, Arzu Tugce; Waaijer, Cathelijn J F; Palmblad, Magnus

    Scientific workflows organize the assembly of specialized software into an overall data flow and are particularly well suited for multi-step analyses using different types of software tools. They are also favorable in terms of reusability, as previously designed workflows could be made publicly available through the myExperiment community and then used in other workflows. We here illustrate how scientific workflows and the Taverna workbench in particular can be used in bibliometrics. We discuss the specific capabilities of Taverna that makes this software a powerful tool in this field, such as automated data import via Web services, data extraction from XML by XPaths, and statistical analysis and visualization with R. The support of the latter is particularly relevant, as it allows integration of a number of recently developed R packages specifically for bibliometrics. Examples are used to illustrate the possibilities of Taverna in the fields of bibliometrics and scientometrics.

    A bibliometric analysis based on the Science Citation Index Expanded (SCI-Expanded) from the Web of Science was carried out to provide insights into research activities and tendencies of the global risk of engineering nanomaterials (ENMs) from 1999 to 2012. The number of publications per year has increased steadily since approximately 2006. The USA produced 41.9% of all pertinent articles followed by China with 14.8% and UK with 9.1%. Environmental Science & Technology, Toxicology, and Journal of Nanoparticle Research were the three most common journals in this field. A synthesized analysis by co-citation and words from author keywords provided the clues to discover the current research emphases. The mainstream research related to risk of ENMs was toxicological effects and ecological risk. Toxicity effect strongly promoted the development of related research in the past 14 years. Research on environmental behavior and ecological risk of ENMs is the fast growing field.

    Full Text Available Measurement of the impact and influence of medical/scientific journals, and of individual researchers has become more widely practiced in recent decades. This is driven, in part, by the increased availability of data regarding citations of research articles, and by increased competition for research funding. Digestive disease research has been identified as a particularly strong discipline in Canada. The authors collected quantitative data on the impact and influence of Canadian digestive health research. The present study involved an analysis of the research impact (Hirsch factor and research influence (Influence factor of 106 digestive health researchers in Canada. Rankings of the top 25 researchers on the basis of the two metrics were dominated by the larger research groups at the University of Toronto (Toronto, Ontario, McMaster University (Hamilton, Ontario, and the Universities of Calgary (Calgary, Alberta and Alberta (Edmonton, Alberta, but with representation by other research groups at the Universities of Manitoba (Winnipeg, Manitoba, Western Ontario (London, Ontario and McGill University (Montreal, Quebec. Female and male researchers had similar scores for the two metrics, as did basic scientists versus clinical investigators. Strategic recruitment, particularly of established investigators, can have a major impact on the ranking of research groups. Comparing these metrics over different time frames can provide insights into the vulnerabilities and strengths of research groups.

    Bibliometric techniques are not yet widely used to enhance retrieval processes in digital libraries, although they offer value-added effects for users. In this workshop we will explore how statistical modelling of scholarship, such as Bradfordizing or network analysis of coauthorship network, can improve re-trieval services for specific communities, as well as for large, cross-domain col-lections. This workshop aims to raise awareness of the missing link between in-formation retrieval (IR) and bibliometrics/scientometrics and to create a common ground for the incorporation of bibliometric-enhanced services into retrieval at the digital library interface.

    2013-02-01

    Full Text Available Background: Web of Science (WoS is an online academic citation index provided by Thomson Reuters which supplies valuable bibliometric information for comparing impact of specific author, organization, or country in science production. The aim of this study was to compare toxicology publications of Iran and Turkey indexed in WoS from bibliometric point of view. Methods: The WoS database was queried based on keywords “Iran” and “Turkey” separately in the “Address” field and refined by “Toxicology” as a category. All records were transferred to Microsoft Excel® application. The dataset were analyzed from different perspectives, such as publication years, number of references and citations, authorship pattern, publications types, affiliated organizations, core subject areas and journals. Results: There were 1178 and 2240 publications that met the criteria during 1993-2011 for Iran and Turkey, respectively. Less than 2% of authors had published more than 25% of all toxicology papers in both countries. The average number of citation per article was about 3.48 for Iranian and 6.73 for Turkish papers. By the time of the analysis, 54.3% of Iranian and 31.6% of Turkish articles had not received any citation. Conclusion: This analysis reveals that top Iranian toxicologists had a better performance than their Turkish counterparts but overall authorship pattern was well-distributed among Turkish researchers and organizations. If Iranian authors desire to achieve first rank of toxicology articles in the Middle East region by 2025, they must try to increase the quantity and quality of their international publications.

    Full Text Available Background: Public health research has gained increasing importance in India's national health policy as the country seeks to address the high burden of disease and its inequitable distribution, and embarks on an ambitious agenda towards universalising health care. Objective: This study aimed at describing the public health research output in India, its focus and distribution, and the actors involved in the research system. It makes recommendations for systematically promoting and strengthening public health research in the country. Design: The study was a bibliometric analysis of PubMed and IndMed databases for years 2000–2010. The bibliometric data were analysed in terms of biomedical focus based on the Global Burden of Disease, location of research, research institutions, and funding agencies. Results: A total of 7,893 eligible articles were identified over the 11-year search period. The annual research output increased by 42% between 2000 and 2010. In total, 60.8% of the articles were related to communicable diseases, newborn, maternal, and nutritional causes, comparing favourably with the burden of these causes (39.1%. While the burdens from non-communicable diseases and injuries were 50.2 and 10.7%, respectively, only 31.9 and 7.5% of articles reported research for these conditions. The north-eastern states and the Empowered-Action-Group states of India were the most under-represented for location of research. In total, 67.2% of papers involved international collaborations and 49.2% of these collaborations were with institutions in the UK or USA; 35.4% of the publications involved international funding and 71.2% of funders were located in the UK or USA. Conclusions: While public health research output in India has increased significantly, there are marked inequities in relation to the burden of disease and the geographic distribution of research. Systematic priority setting, adequate funding, and institutional capacity building are

    We conducted a bibliometric and content analysis of research on health inequalities produced in Latin American and Caribbean countries. In our bibliometric analysis (n = 576), we used indexed material published between 1971 and 2000. The content analysis (n = 269) covered the period 1971 to 1995 and included unpublished material. We found recent rapid growth in overall output. Brazil, Chile, and Mexico contributed mostly empirical research, while Ecuador and Argentina produced more conceptual studies. We found, in the literature reviewed, a relative neglect of gender, race, and ethnicity issues. We also found remarkable diversity in research designs, however, along with strong consideration of ecological and ethnographic methods absent in other research traditions. PMID:14652329

    2014-01-01

    The Gap Analysis Program (GAP) of the U.S. Geological Survey (USGS) produces geospatial datasets providing information on land cover, predicted species distributions, stewardship (ownership and conservation status), and an analysis dataset which synthesizes the other three datasets. The intent in providing these datasets is to support the conservation of biodiversity. The datasets are made available at no cost. The initial datasets were created at the state level. More recent datasets have been assembled at regional and national levels. GAP entered an agreement with the Policy Analysis and Science Assistance branch of the USGS to conduct an evaluation to describe the effect that using GAP data has on those who utilize the datasets (GAP users). The evaluation project included multiple components: a discussion regarding use of GAP data conducted with participants at a GAP conference, a literature review of publications that cited use of GAP data, and a survey of GAP users. The findings of the published literature search were used to identify topics to include on the survey. This report summarizes the literature search, the characteristics of the resulting set of publications, the emergent themes from statements made regarding GAP data, and a bibliometric analysis of the publications. We cannot claim that this list includes all publications that have used GAP data. Given the time lapse that is common in the publishing process, more recent datasets may be cited less frequently in this list of publications. Reports or products that used GAP data may be produced but never published in print or released online. In that case, our search strategies would not have located those reports. Authors may have used GAP data but failed to cite it in such a way that the search strategies we used would have located those publications. These are common issues when using a literature search as part of an evaluation project. Although the final list of publications we identified is not

    Jung, Minsoo

    2013-01-01

    This study examined the 2 preventive medicine journals in North Korea by using coauthor and keyword network analysis on the basis of medical informatics and bibliometrics. Used were the Journal of Chosun Medicine (JCM) and the Journal of Preventive Medicine (JPM) (from the first volume of 1997 to the fourth volume of 2006) as data. Extracted were 1734 coauthors from 1104 articles and 1567 coauthors from 1172 articles, respectively. Huge single components were extracted in the coauthor analysis, which indicated a tendency toward structuralization. However, the 2 journals differed in that JPM showed a relative tendency toward specialization, whereas JCM showed one toward generalization. Seventeen and 33 keywords were extracted from each journal in the keyword analysis; JCM mainly concerned pathological research, whereas JPM mainly concerned virus and basic medicine studies that were based on infection and immunity. In contrast to South Korea, North Korea has developed Juche medicine, which came from self-reliance ideology and gratuitous medical service. According to the present study, their ideology was embodied by the discovery of bacteria, study on immune system, and emphasis on pathology, on the basis of experimental epidemiology. However, insufficient research has been conducted thus far on population health and its related determinants.

    Scott R Rosas

    Full Text Available Evaluative bibliometrics uses advanced techniques to assess the impact of scholarly work in the context of other scientific work and usually compares the relative scientific contributions of research groups or institutions. Using publications from the National Institute of Allergy and Infectious Diseases (NIAID HIV/AIDS extramural clinical trials networks, we assessed the presence, performance, and impact of papers published in 2006-2008. Through this approach, we sought to expand traditional bibliometric analyses beyond citation counts to include normative comparisons across journals and fields, visualization of co-authorship across the networks, and assess the inclusion of publications in reviews and syntheses. Specifically, we examined the research output of the networks in terms of the a presence of papers in the scientific journal hierarchy ranked on the basis of journal influence measures, b performance of publications on traditional bibliometric measures, and c impact of publications in comparisons with similar publications worldwide, adjusted for journals and fields. We also examined collaboration and interdisciplinarity across the initiative, through network analysis and modeling of co-authorship patterns. Finally, we explored the uptake of network produced publications in research reviews and syntheses. Overall, the results suggest the networks are producing highly recognized work, engaging in extensive interdisciplinary collaborations, and having an impact across several areas of HIV-related science. The strengths and limitations of the approach for evaluation and monitoring research initiatives are discussed.

    Full Text Available This work aimed to make a bibliometric analysis on empirical studies that focus on the reverse logistics process. Papers published in two major events of management and a production engineering were collected during the years 2007-2012. To perform the analysis assumptions were adopted as the concepts of innovation and decision-making. 43 articles were analyzed and it was found that, in most cases, organizations choose to deploy reverse logistics as a means to solving problems related to environmental laws and regulations and after its implementation, the decision-making process related to the network of companies that perform reverse logistics remains restricted to the adopter company, thus becoming a centralized decision-making process. It was also found that reverse logistics is, in most cases, an innovation in the supply chain, it provides a new way to manage and operate the return and recycling of waste products and generating competitive advantages in the form of increased net income and better picture of the organization to its partners and customers.

    2015-01-15

    Based on the samples of 113,468 publications on environmental assessment (EA) from the past 20 years, we used a bibliometric analysis to study the literature in terms of trends of growth, subject categories and journals, international collaboration, geographic distribution of publications, and scientific research issues. By applying thresholds to network centralities, a core group of countries can be distinguished as part of the international collaboration network. A frequently used keywords analysis found that the priority in assessment would gradually change from project environmental impact assessment (EIA) to strategic environmental assessment (SEA). Decision-theoretic approaches (i.e., environmental indicator selection, life cycle assessment, etc.), along with new technologies and methods (i.e., the geographic information system and modeling) have been widely applied in the EA research field over the past 20 years. Hot spots such as “biodiversity” and “climate change” have been emphasized in current EA research, a trend that will likely continue in the future. The h-index has been used to evaluate the research quality among countries all over the world, while the improvement of developing countries' EA systems is becoming a popular research topic. Our study reveals patterns in scientific outputs and academic collaborations and serves as an alternative and innovative way of revealing global research trends in the EA research field.

    In order to provide a reference and theoretical guidance of the evaluation of electronic medical record (EMR) and establishment of evaluation system in China, we applied a bibliometric analysis to assess the application of methodologies used at home and abroad, as well as to summarize the advantages and disadvantages of them. We systematically searched international medical databases of Ovid-MEDLINE, EBSCOhost, EI, EMBASE, PubMed, IEEE, and China's medical databases of CBM and CNKI between Jan. 1997 and Dec. 2012. We also reviewed the reference lists of articles for relevant articles. We selected some qualified papers according to the pre-established inclusion and exclusion criteria, and did information extraction and analysis to the papers. Eventually, 1 736 papers were obtained from online database and other 16 articles from manual retrieval. Thirty-five articles met the inclusion and exclusion criteria and were retrieved and assessed. In the evaluation of EMR, US counted for 54.28% in the leading place, and Canada and Japan stood side by side and ranked second with 8.58%, respectively. For the application of evaluation methodology, Information System Success Model, Technology Acceptance Model (TAM), Innovation Diffusion Model and Cost-Benefit Access Model were widely applied with 25%, 20%, 12.5% and 10%, respectively. In this paper, we summarize our study on the application of methodologies of EMR evaluation, which can provide a reference to EMR evaluation in China.

    2012-01-01

    Full Text Available This article examines some of the most common methodological problems in the evaluation of academic journals in the field of communication, based on the content analysis of the ten journals with the highest impact factors in the Social Sciences Citation Index. The analysis focuses on establishing the academic and research origins and links of the authors of the articles published by these scientific publications, as well as the most predominant subject matters, genres and methodologies among the articles of these publications. This research aims to achieve two objectives: On the one hand, to analyse the role of the evaluation of communication journals in the assessment of research, which will allow us to show the difficulties of applying the bibliometric methods used by Thomson Scientific to determine the impact of journals and, on the other hand, to establish a development framework for those Spanish communication journals that meet some of the requirements of the Social Sciences Citation Index but are not yet indexed in it, either because their impact factor is still low or because of their lack of international dissemination. This research has been financed by the University of Malaga’s Research Institute for Public Relations.

    A bibliometric analysis was conducted to examine the progress and future research trends of non-point source (NPS) pollution during the years 1991-2015 based on the Science Citation Index Expanded (SCI-Expanded) of Web of Science (WoS). The publications referencing NPS pollution were analyzed including the following aspects: document type, publication language, publication output and characteristics, subject category, source journal, distribution of country and institution, author keywords, etc. The results indicate that the study of NPS pollution demonstrated a sharply increasing trend since 1991. Article and English were the most commonly used document type and language. Environmental sciences and ecology, water resources, and engineering were the top three subject categories. Water science and technology ranked first in distribution of journal, followed by Science of the total environment and Environmental Monitoring and Assessment. The USA took a leading position in both quantity and quality, playing an important role in the research field of NPS pollution, followed by the UK and China. The most productive institution was the Chinese Academy of Sciences (Chinese Acad Sci), followed by Beijing Normal University and US Department of Agriculture's Agricultural Research Service (USDA ARS). The analysis of author keywords indicates that the major hotspots of NPS pollution from 1991 to 2015 contained "water," "model," "agriculture," "nitrogen," "phosphorus," etc. The results provide a comprehensive understanding of NPS pollution research and help readers to establish the future research directions.

    Full Text Available Aim. Bibliometric studies can be used to evaluate the quantitative scientific performance on a specific topic via evaluating the accumulation of scientific data. Interpreting quantitative performance of a country with respect to bibliometric analyses is an important way to assess the quality and quantity of that country’s contribution to the dissemination of medical evidences about a topic. In this study, we aimed to make a quantitative analysis of the scientific publications related to “Polycystic Ovary Syndrome” and also to investigate publications originating from Turkish institutions and authors, which are published in Science Citation Index Expanded covered medical journals. Method. We retrospectively searched papers published in the field of polycystic ovary syndrome between 1980 and 2012 by using the Web of Science software. Papers that were published in Science Citation Index Expanded covered journals were taken into account. Results. Web of Science based search on the field of “Polycystic Ovary Syndrome” through the database of Science Citation Index Expanded from 1980 to the date of the study (June 29, 2012, revealed 8891 English scientific documents. Among these, 2836 (31.9% were from United States of America, followed by England (9.75%, Italy (8.45%, Turkey (5.34%. The international scientific repertory on polycystic ovary syndrome was relatively poor in the beginning of 1980s, however; we observed an international acceleration with respect to the publication number after 1990s. Publications from Turkey on the other hand showed up only after 1990s. Turkey’s contribution to international repertory of polycystic ovary syndrome research speeded up after 2000s. When the ranking of the authors with respect to the number of publications was evaluated, Azziz R was found to be the first, followed by Legro RS, and Franks S. Yildiz BO, Kelestimur F, and Yarali H were the first three among Turkish authors. Fertility and Sterility

    2016-01-01

    The aim of this study was to provide a framework to evaluate bibliometric indicators as decision support tools from a decision making perspective and to examine the information value of early career publication rate as a predictor of future productivity. We used ROC analysis to evaluate a bibliometric indicator as a tool for binary decision making. The dataset consisted of 451 early career researchers in the mathematical sub-field of number theory. We investigated the effect of three different definitions of top performance groups-top 10, top 25, and top 50 %; the consequences of using different thresholds in the prediction models; and the added prediction value of information on early career research collaboration and publications in prestige journals. We conclude that early career performance productivity has an information value in all tested decision scenarios, but future performance is more predictable if the definition of a high performance group is more exclusive. Estimated optimal decision thresholds using the Youden index indicated that the top 10 % decision scenario should use 7 articles, the top 25 % scenario should use 7 articles, and the top 50 % should use 5 articles to minimize prediction errors. A comparative analysis between the decision thresholds provided by the Youden index which take consequences into consideration and a method commonly used in evaluative bibliometrics which do not take consequences into consideration when determining decision thresholds, indicated that differences are trivial for the top 25 and the 50 % groups. However, a statistically significant difference between the methods was found for the top 10 % group. Information on early career collaboration and publication strategies did not add any prediction value to the bibliometric indicator publication rate in any of the models. The key contributions of this research is the focus on consequences in terms of prediction errors and the notion of transforming uncertainty

    The research on indications of acu-moxibustion is very important for effectively guiding clinical practice. In the present paper, the authors retrieved domestic literature about researches on the disease-spectrum or indications of acu-moxibustion therapy in recent 10 years, and made a bibliometrics analysis according to the described research methods, publishing year, quantity and their proportionate relationship. A total of 18 qualified original papers involving 414 illnesses or clinical conditions were included in the present paper. Among the 414 kinds of clinical conditions or illnesses, 72 were considered to be suitable candidates for acu-moxibustion therapy, including functional dyspepsia, herpes zoster, irritable bowel syndrome, gastrointestinal dysfunction, scapulohumeral periarthritis, cervical syndrome, dyssomnia, acne (cyst type), chronic urticaria, regional neurodermatitis, pain, itching, etc. which belong to illness-spectrum grade-I. Generally, the acu-moxibustion therapy is, in clinical effects, relatively poorer for structural diseases which are attributed to grade-II or grade-III type. Nevertheless, the diversity of clinical indications of acu-moxibustion has been confirmed nowadays. Current studies on illness-spectrum are of certain uniformity and comprehensiveness, but need further extending and perfecting, and need more standardized methods corresponding to principles of the evidence-based medicine.

    Objective During the past 20 years, over 1,400 doctors have been certified as emergency physicians in Korea. The number of scientific publications in the field of emergency medicine has also increased. This study aims to evaluate the research productivity of academic emergency physicians in South Korea. Methods Articles published from 1996 to 2015 by authors affiliated with Korean emergency departments were retrieved using Pubmed, Embase, and Web of Science. Research productivity was analyzed quantitatively to ascertain the number of articles for publication type and year. The performance of these articles was also analyzed qualitatively using impact factor, citation number, and Hirsch index. Bibliometric analysis was performed by researching Web of Science, Scopus, and Google Scholar. Results A total of 858 articles with 293 Korean authors as the first or corresponding authors were published across 191 journals. The number of publications increased continuously. The most common publication type was original article (n=618), the most commonly studied research topic was resuscitation medicine (n=110), and the average impact factor of the original articles was 2.158. The highest h-index was 17 and, using Web of Science, the maximum number of citations was found to be 85. Conclusion This study suggests that the research productivity of Korean authors in the emergency medicine field has progressed steadily during the last 10 years. However, qualitative indexes, such as the number of citations and h-index value, remain low. PMID:28168231

    We investigated the research publications on thermal spray in the period of 1985-2015 using the data from Web of Science, Scopus and SciVal®. Bibliometrics analysis was employed to elucidate the country and institution distribution in various thermal spray research areas and to characterize the trends of topic change and technology progress. Results show that China, USA, Japan, Germany, India and France were the top countries in thermal spray research, and Xi'an Jiaotong University, Universite de Technologie Belfort-Montbeliard, Shanghai Institute of Ceramics, ETH Zurich, National Research Council of Canada, University of Limoges were among the top institutions that had high scholarly research output during 2005-2015. The terms of the titles, keywords and abstracts of the publications were analyzed by the Latent Dirichlet Allocation model and visually mapped using the VOSviewer software to reveal the progress of thermal spray technology. It is found that thermal barrier coating was consistently the main research area in thermal spray, and high-velocity oxy-fuel spray and cold spray developed rapidly in the last 10 years.

Methods: A bibliometric research was carried out using SCOPUS database. The analysis unit was original research articles published from 2000 to 2011, that dealt with leishmaniasis and that included at least one South American author. The following items were obtained for each article: journal name, language, year of publication, number of authors, institutions, countries, and others variables. Results: 3,174 articles were published, 2,272 of them were original articles. 1,160 different institutional signatures, 58 different countries and 398 scientific journals were identified. Brazil was the country with more articles (60.7% and Oswaldo Cruz Foundation (FIOCRUZ had 18% of Brazilian production, which is the South American nucleus of the major scientific network in Leishmaniasis. Conclusions: South American scientific production on Leishmaniasis published in journals indexed in SCOPUS is focused on Brazilian research activity. It is necessary to strengthen the collaboration networks. The first step is to identify the institutions with higher production, in order to perform collaborative research according to the priorities of each country.

    Delineating the emergence of nanotechnologies that offer new functionalities is an important element in an anticipatory approach to the governance of nanotechnology and its potential impacts. This paper examines the transition to next generation active nanotechnologies which incorporate functions that respond to the environment or systems concepts that combine devices and structures that are dynamic and which may change their states in use. We develop an approach to identifying these active nanotechnologies and then use bibliometric analysis to examine the extent of research papers and patents involving these concepts. We also examine references to environmental, health, and safety concepts in these papers, given that these next generation nanotechnologies are likely to have risk profiles that are different from those of first-generation passive nanomaterials. Our results show a steady growth overall in focus on active nanotechnologies in the research literature and in patents over the study period of 1990-2010. We also find an increase in consideration given to environmental, health, and safety topics. While gaps are highlighted in our understanding of research and innovation in active nanotechnologies, the results suggest that there is beginning to be a shift to active nanotechnologies, with the implication that governance processes need to be conscious of this shift and to prepare for it.

    Aim: To determine whether there is evidence of a reduction in radiology research activity in the UK following the implementation of the European research ethics legislation, which came in to force in 2001 and has been widely criticised as an impediment to research. Materials and methods: A bibliometric analysis was performed by searching PubMed for all first-author publications from UK departments of 'radiology' or 'medical imaging' between 1995 and 2007. Results were subcategorized into those papers published in the highest cited general radiology journals and by publication type: original research, reviews, and case reports. Results: From 1995 to 2007 the total number of publications rose by 6.5% from 137 to 146 with the increase occurring in non-general radiology journals. Original articles fell from 18 in 1995 to 12 in 2003, but then rose to 24 by 2007 (33% rise). This dip was paralleled by a fall and then recovery in case report publications. The most dramatic change has been in the number of review articles, which has increased more than eightfold from seven in 1995 to 65 in 2007 to become the most common form of publication. Conclusion: The overall number of original scientific articles, published by first-author UK radiologists, has increased slightly over the last 12 years despite a temporary fall associated with the introduction of new research ethics legislation.

    To meet the energy requirements of sustainable economic growth, policymakers, analysts, and business leaders have increasingly turned to the role that energy efficiency might play. This has resulted in a growing energy efficiency literature, which is examined in this paper. Using bibliometric techniques, we analyze the database of Science Citation Index Expanded and Social Sciences Citation Index covering the 1991-2010 period. Of the 8,244 publications, 78.8 % were journal articles, and about 95.5 % were published in English. Based on the h-index, an evaluative indicator, the USA has produced the most influential set of publications on energy efficiency, followed by Canada, UK, Japan, and China. In contrast, China is second to the USA in the volume of its publications. Correspondingly, the University of California at Berkeley, Chinese Academy of Sciences, and Tsinghua University were the most productive research organizations. The three most common subjects examined in this body of research were 'energy and fuels', 'environmental sciences', and 'electrical and electronic engineering'. Energy Policy has been the most productive journal, and 'A water and heat management model for proton-exchange-membrane fuel-cells', has had the most citations (587 through May 2012). Based on an analysis of article titles and keywords, we conclude that the hotspots of energy efficiency research have been green communications, renewable energy, and energy sustainability; green communications, in particular, has developed rapidly as a focus of energy efficiency publications in recent years.

    Since the first description of Guillain-Barré syndrome (GBS) 100 years ago, the concept of this syndrome has changed remarkably. The purpose of our study was to identify and characterize the most-cited articles that have contributed to advancing the understanding of GBS. Based on the database of Journal Citation Reports, we selected 554 journals that were considered as potential sources of reports on studies related to clinical neurology and general medicine. The Web of Science search tools were used to identify the most-cited articles relevant to GBS or other variants in the selected journals. Of the selected articles, 18 were review articles and the remainder were original articles or included only a few case series. Among the original articles, 13 described basic research associated with immunological pathogenesis involving anti-ganglioside antibodies. Most of the original studies (42/64, 66%) published after 1990 evaluated anti-ganglioside antibodies that mediated axonal GBS or Miller Fisher syndrome, with only a small number of the papers involving electrodiagnostic medicine (n = 4). Our bibliometric analysis has yielded a detailed list of the top-100 cited articles in the field of GBS.

    A bibliometric analysis based on the Science Citation Index Expanded from the Web of Science was carried out to provide insights into research activities and tendencies of the global drinking water from 1992 to 2011. Study emphases included performance of publication covering annual outputs, mainstream journals, Web of Science categories, leading countries, institutions, research tendencies and hotspots. The results indicated that annual output of the related scientific articles increased steadily. Water Research, Environmental Science and Technology, and Journal American Water Works Association were the three most common journals in drinking water research. The USA took a leading position out of 168 countries/territories, followed by Japan and Germany. A summary of the most frequently used keywords obtained from words in paper title analysis, author keyword analysis and KeyWords Plus analysis provided the clues to discover the current research emphases. The mainstream research related to drinking water was water treatment methods and the related contaminants. Disinfection process and consequent disinfection by-products attracted much attention. Ozonation and chlorination in disinfection, and adsorption were common techniques and are getting popular. Commonly researched drinking water contaminants concerned arsenic, nitrate, fluoride, lead, and cadmium, and pharmaceuticals emerged as the frequently studied contaminants in recent years. Disease caused by contaminants strongly promoted the development of related research. - Highlights: ► Drinking water research was characterized based on SCI-Expanded during 1992–2011. ► Research emphases were obtained from title, author keywords and KeyWords Plus. ► Ozonation, chlorination and adsorption were common techniques and are getting popular. ► Emerging contaminants concerned arsenic, nitrate, fluoride, lead, and cadmium.

    In this paper, the results of a bibliometric and visual analysis of geo-ontology research articles collected from the Web of Science (WOS) database between 1999 and 2014 are presented. The numbers of national institutions and published papers are visualized and a global research heat map is drawn, illustrating an overview of global geo-ontology research. In addition, we present a chord diagram of countries and perform a visual cluster analysis of a knowledge co-citation network of references, disclosing potential academic communities and identifying key points, main research areas, and future research trends. The International Journal of Geographical Information Science, Progress in Human Geography, and Computers & Geosciences are the most active journals. The USA makes the largest contributions to geo-ontology research by virtue of its highest numbers of independent and collaborative papers, and its dominance was also confirmed in the country chord diagram. The majority of institutions are in the USA, Western Europe, and Eastern Asia. Wuhan University, University of Munster, and the Chinese Academy of Sciences are notable geo-ontology institutions. Keywords such as "Semantic Web," "GIS," and "space" have attracted a great deal of attention. "Semantic granularity in ontology-driven geographic information systems, "Ontologies in support of activities in geographical space" and "A translation approach to portable ontology specifications" have the highest cited centrality. Geographical space, computer-human interaction, and ontology cognition are the three main research areas of geo-ontology. The semantic mismatch between the producers and users of ontology data as well as error propagation in interdisciplinary and cross-linguistic data reuse needs to be solved. In addition, the development of geo-ontology modeling primitives based on OWL (Web Ontology Language)and finding methods to automatically rework data in Semantic Web are needed. Furthermore, the topological

    A bibliometric analysis based on the Science Citation Index-Expanded (SCI-Expanded) database from the Web of Science was performed to review urban heat island (UHI) research from 1991 to 2015 and statistically assess its developments, trends, and directions. In total, 1822 papers published in 352 journals over the past 25 years were analyzed for scientific output; citations; subject categories; major journals; outstanding keywords; and leading countries, institutions, authors, and research collaborations. The number of UHI-related publications has continuously increased since 1991. Meteorology atmospheric sciences, environmental sciences, and construction building technology were the three most frequent subject categories. Building and Environment, International Journal of Climatology, and Theoretical and Applied Climatology were the three most popular publishing journals. The USA and China were the two leading countries in UHI research, contributing 49.56% of the total articles. Chinese Academy of Science, Arizona State University, and China Meteorological Administration published the most UHI articles. Weng QH and Santamouris M were the two most prolific authors. Author keywords were classified into four major groups: (1) research methods and indicators, e.g., remote sensing, field measurement, and models; (2) generation factors, e.g., impervious urban surfaces, urban geometry, waste heat, vegetation, and pollutants; (3) environmental effects, e.g., urban climate, heat wave, ecology, and pollution; and (4) mitigation and adaption strategies, e.g., roof technology cooling, reflective cooling, vegetation cooling, and urban geometry cooling. A comparative analysis of popular issues revealed that UHI determination (intensity, heat source, supporting techniques) remains the central topic, whereas UHI impacts and mitigation strategies are becoming the popular issues that will receive increasing scientific attention in the future. Modeling will continue to be the

    In French hospitals, the progressive setting up of the new rating systems has obliged the university hospitals to justify a certain amount of activities such as research, training or moreover recourse, which are specific missions of the university hospitals. In order to justify research activities, the Lille University Hospital has developed for now three years SIGAPS, a full-web bibliometric software which census and analyse, the scientific publications referenced in the Medline database. After data downloading, each article is classified on a 6 levels "quality scale derived from the impact factors. The system then performs, for a researcher or a team, a report allowing a quantitative and qualitative analysis. Started in Lille in November 2004, the inventory and analysis of data is now ending. For the period 2001-2004, 2814 articles have been published in 700 different journals. The total number of articles increased from 688 in 2001 to 757 in 2004. The mean impact factor was equal to 2.26 and 15.5 % of articles were classified as A, 20.9% as B. Those results confirm the high level of research of the University Hospital of Lille, in agreement with two other national studies which ranks our establishment at the 6th position for medical research activities among the French University Hospitals. Currently a similar evaluation has now began in the 9 other university hospital which have subscribed to the SIGAPS project. We works currently on new indicators as patents, thesis or conferences, or access to other databases as Sciencedirect or Scopus via the RIS format. The next step in the project is the implementation of a meta-base which will federate the information provided by each SIGAPS system. This meta-base will then allow us to perform comparisons between different hospitals, determine the national "sites of excellence" and create some clinical and research networks.

    2009-01-01

    AIM: To analyze the MEDLINE-indexed publications in gastroenterology specialty journals from 2001 to 2007. Special attention was paid to specific types of articles, the number of publications for individual authors and the author count in each journal. METHODS: The bibliographic entries of papers belonging to journals listed under the subject heading of "gastroenterology" were downloaded from MEDLINE on the PubMed web site. The analysis was limited to journal articles published between January 1, 2001 and December 31, 2007. The analytical dimensions of an article included journal, publication year, publication type, and author name (the last name and initials). RESULTS: According to MEDLINE, 81 561 articles were published in 91 gastroenterology journals from 2001 to 2007. The number of articles increased from 9447 in 2001 to 13 340 in 2007. Only 12 journals had more than 2000 articles indexed in MEDLINE. The " World Journal of Gastroenterology" had the largest number of publications (5684 articles), followed by " Hepato-Gastroenterology" (3036) and " Gastrointestinal Endoscopy" (3005). Of all the articles published, reviews accounted for 17.2% and case reports for 15.4%. Only 3739 randomized controlled trials (4.6% of all articles) were published and their annual number increased from 442 in 2001 to 572 in 2007. Among 141 741 author names appearing in the articles of gastroenterology journals, 92 429 had published only in one journal, 22 585 in two journals, 9996 in three journals, and 16 731 in more than three journals. The " World Journal of Gastroenterology" had the greatest number of authors (17 838), followed by " Gastroenterology" (12 770), " Digestive Diseases and Sciences" (11 395), " American Journal of Gastroenterology" (10 889), and " Hepatology" (10 588). CONCLUSION: Global gastroenterology publications displayed a continuous growth in the new millennium. The change was most striking in certain journals. Regular bibliometric analyses on the trends and

    Energy crisis, climate changes, and biodiversity losses have reinforced the drive for more ecologically-based approaches for environmental management. Such approaches are characterized by the use of organisms rather than energy-consuming technologies. Although earthworms are believed to be potentially useful organisms for managing ecosystem services, there is actually no quantification of such a trend in literature. This bibliometric analysis aimed to measure the evolution of the association of "earthworms" and other terms such as ecosystem services (primary production, nutrient cycling, carbon sequestration, soil structure, and pollution remediation), "ecological engineering" or "biodiversity," to assess their convergence or divergence through time. In this aim, we calculated the similarity index, an indicator of the paradigmatic proximity defined in applied epistemology, for each year between 1900 and 2009. We documented the scientific fields and the geographical origins of the studies, as well as the land uses, and compare these characteristics with a 25 years old review on earthworm management. The association of earthworm related keywords with ecosystem services related keywords was increasing with time, reflecting the growing interest in earthworm use in biodiversity and ecosystem services management. Conversely, no significant increase in the association between earthworms and disciplines such as ecological engineering or restoration ecology was observed. This demonstrated that general ecologically-based approaches have yet to emerge and that there is little exchange of knowledge, methods or concepts among balkanized application realms. Nevertheless, there is a strong need for crossing the frontiers between fields of application and for developing an umbrella discipline to provide a framework for the use of organisms to manage ecosystem services.

    2011-11-01

    Full Text Available Abstract Background While environmental research addresses scientific questions of possible societal relevance, it is unclear to what degree research focuses on environmental chemicals in need of documentation for risk assessment purposes. Methods In a bibliometric analysis, we used SciFinder to extract Chemical Abstract Service (CAS numbers for chemicals addressed by publications in the 78 major environmental science journals during 2000-2009. The Web of Science was used to conduct title searches to determine long-term trends for prominent substances and substances considered in need of research attention. Results The 119,636 journal articles found had 760,056 CAS number links during 2000-2009. The top-20 environmental chemicals consisted of metals, (chlorinated biphenyls, polyaromatic hydrocarbons, benzene, and ethanol and contributed 12% toward the total number of links- Each of the top-20 substances was covered by 2,000-10,000 articles during the decade. The numbers for the 10-year period were similar to the total numbers of pre-2000 articles on the same chemicals. However, substances considered a high priority from a regulatory viewpoint, due to lack of documentation, showed very low publication rates. The persistence in the scientific literature of the top-20 chemicals was only weakly related to their publication in journals with a high impact factor, but some substances achieved high citation rates. Conclusions The persistence of some environmental chemicals in the scientific literature may be due to a 'Matthew' principle of maintaining prominence for the very reason of having been well researched. Such bias detracts from the societal needs for documentation on less well known environmental hazards, and it may also impact negatively on the potentials for innovation and discovery in research.

  11. A bibliometric analysis of 50 years of worldwide research on statistical process control

    Directory of Open Access Journals (Sweden)

    Fabiane Letícia Lizarelli

    Full Text Available Abstract An increasing number of papers on statistical process control (SPC has emerged in the last fifty years, especially in the last fifteen years. This may be attributed to the increased global competitiveness generated by innovation and the continuous improvement of products and processes. In this sense, SPC has a fundamentally important role in quality and production systems. The research in this paper considers the context of technological improvement and innovation of products and processes to increase corporate competitiveness. There are several other statistical technics and tools for assisting continuous improvement and innovation of products and processes but, despite the limitations in their use in the improvement projects, there is growing concern about the use of SPC. A gap between the SPC technics taught in engineering courses and their practical applications to industrial problems is observed in empirical research; thus, it is important to understand what has been done and identify the trends in SPC research. The bibliometric study in this paper is proposed in this direction and uses the Web of Science (WoS database. Data analysis indicates that there was a growth rate of more than 90% in the number of publications on SPC after 1990. Our results reveal the countries where these publications have come from, the authors with the highest number of papers and their networks. Main sources of publications are also identified; it is observed that the publications of SPC papers are concentrated in some of the international research journals, not necessarily those with the major high-impact factors. Furthermore, the papers are focused on industrial engineering, operations research and management science fields. The most common term found in the papers was cumulative sum control charts, but new topics have emerged and have been researched in the past ten years, such as multivariate methods for process monitoring and nonparametric methods.

    The sustainable management of groundwater resources is a pressing necessity for most countries. As most of the Arab world is facing severe water scarcity, threats of depletion of non-renewable groundwater, and problems of pollution and salt-water intrusions into groundwater aquifers, much effort should be devoted to eliminate these dangers in advance. This work was devoted to bring up insights into Arab world research activities in groundwater, which is a crucial task to identify their status and can help in shaping up and improving future research activities. A bibliometric analysis has been conducted to track these activities. The study identified 1417 documents which represent 3.3% of global research productivity. Egypt was the most productive country (313; 22.1%), followed by Saudi Arabia (254; 17.9%). Total citations were 9720 with an average of 6.9. The h-index of the retrieved documents was 39, and the highest one was 22 for Egypt. The most common subject category was Environmental Science, and the most productive journal was Arabian Journal of Geosciences (99; 7.0%). In international research collaboration, France was the most collaborated country with Arab world (125; 8.8%), followed by the United States (113; 8.0%). The most productive institution was King Abdul-Aziz University, Saudi Arabia (66; 4.7%). The outcomes shows remarkable improvements in groundwater research activities originated from the Arab world. Even though, constructive efforts should be pursued vigorously to bridge the gaps in groundwater-based research. Moreover, promotion of better evaluation tools to assess the risks arising from the mismanagement of groundwater resources is required urgently.

In an attempt to answer this question, this study conducts a bibliometric analysis of the Turkish Journal of Psychology (Turk Psikoloji Dergisi [TPD] as indexed in the Social Science Citation Index Multidisciplinary Psychology since 1995, volume 10, issue 35. Descriptive data showed that TPD published a total of 215 articles, about 11 per year, in Turkish (84.65% and English (15.35%. On an average, an article was authored by 2 (2.01 authors and the article/unique author ratio was about 1:1 (.98. Apart from Turkey, authors were affiliated with the USA, Canada, The Netherlands, Australia, Cyprus, England, and Germany. Most of the publications were products of authors affiliated with universities in Ankara, Turkey. TPD was ranked 115 out of 126 journals in the category of Multidisciplinary Psychology in the Journal Citation Reports-Social Sciences Edition, with an impact factor of 0.214 in 2012 and a 5-year impact factor of 0.154. Aside from the most common words such as the, in, and so on, "Turkish" (n = 30, followed by "study" and "memory," were the most frequently used words in titles; "study," (n = 325 "memory," (n = 206 and "between" (n = 201 were the most frequently used words in abstracts. On an average, articles had about five keywords, including about four keywords unique to the article. These findings suggest that TPD is an extremely local, but highly impactful journal publishing articles on very diverse topics from self to culture, and from memory to depression to scale development.

    2008-09-01

    Although the fields of bibliometrics and citation analysis have existed for many years, relatively few studies have specifically focused on the dermatological literature. This article reviews citation-based research in the dermatology journals, with a particular interest in manuscripts that have included Contact Dermatitis as part of their analysis. Overall, it can be seen that the rise of bibliometrics during the mid-20th century and its subsequent application to dermatology has provided an interesting insight into the progression of research within our discipline. Further investigation of citation trends and top-cited papers in skin research periodicals would certainly help complement the current body of knowledge.

    In recent years, many epidemiological and toxicological studies have investigated the adverse effects of air particulate matter (PM) on the cardiovascular system. However, it is difficult for the researchers to have a timely and effective overall command of the latest characteristics and popular topics in such a wide field. Different from the previous reviews, in which the research characteristics and trends are empirically concluded by experts, we try to have a comprehensive evaluation of the above topics for the first time by bibliometric analysis, a quantitative tool in information exploration. This study aims to introduce the bibliometric method into the field of PM and cardiovascular system. The articles were selected by searching PubMed/MEDLINE (from 2007 to 2012) using Medical Subject Headings (MeSH) terms "particulate matter" and "cardiovascular system". A total of 935 eligible articles and 1895 MeSH terms were retrieved and processed by the software Thomson Data Analyzer (TDA). The bibliographic information and the MeSH terms of these articles were classified and analyzed to summarize the research characteristics. The top 200 high-frequency MeSH terms (the cumulative frequency percentage was 74.2%) were clustered for popular-topic conclusion. We summarized the characteristics of published articles, of researcher collaborations and of the contents. Ten clusters of MeSH terms are presented. Six popular topics are concluded and elaborated for reference. Our study presents an overview of the characteristics and popular topics in the field of PM and cardiovascular system in the past five years by bibliometric tools, which may provide a new perspective for future researchers.

    The objectives of this bibliometric analysis of the scientific literature were to describe the research subjects and the international collaborations in the field of research on infectious diseases in livestock animals including fishes and honeybees. It was based on articles published worldwide from 2006 through 2013. The source of data was the Web of Science, Core collection(®) and only papers fully written in English were considered. Queries were built that combined 130 descriptors related to animal species and 1213 descriptors related to diseases and pathogens. To refine and assess the accuracy of the extracted database, supplementary filters were applied to discard non-specific terms and neighbouring topics, and numerous tests were carried out on samples. For pathogens, annotation was done using a thematic terminology established to link each disease with its corresponding pathogen, which was in turn classified according to its family. A total of 62,754 articles were published in this field during this 8-year period. The average annual growth rate of the number of papers was 5%. This represents the reference data to which we compared the average annual growth rate of articles produced in each of the sub-categories that we defined. Thirty-seven percent of the papers were dedicated to ruminant diseases. Poultry, pigs and fishes were covered by respectively 21, 13 and 14% of the total. Thirty-seven percent of papers concerned bacteria, 33% viruses, 19% parasites, 2% prions, the remaining being multi-pathogens. Research on virology, especially on pigs and poultry, is increasing faster than the average. There also is increasing interest in monogastric species, fish and bees. The average annual growth rate for Asia was 10%, which is high compared to 3% for Europe and 2% for the Americas, indicating that Asia is currently playing a leading role in this field. There is a well established network of international collaborations. For 75% of the papers, the co

    To analyze the performance and quality of intraoperative radiation therapy (IORT) publications identified in medical databases during a recent period in terms of bibliographic metrics. A bibliometric search was conducted for IORT papers published in the PubMed database between 1997 and 2013. Publication rate was used as a quantity indicator; the 2012 Science Citation Index Impact Factor as a quality indicator. Furthermore, the publications were stratified in terms of study type, scientific topic reported, year of publication, tumor type and journal specialty. We performed a one-way analysis of variance (ANOVA) to determine differences between the means of the analyzed groups. Among the total of 207 journals, articles were reported significantly more frequently in surgery (n = 399, 41 %) and radiotherapy journals (n = 273, 28 %; p < 0.01). The highest impact factor was achieved by clinical oncology journals (p < 0.01). The majority of identified articles were retrospective cohort reports (n = 622, 64 %), followed by review articles (n = 204, 21 %; p < 0.001). Regarding primary topic, reports on cancer outcome following specific tumor therapy were most frequently published (n = 661, 68 %; p < 0.001) and gained the highest mean impact factor (p < 0.01). Gastrointestinal tumor reports were represented most frequently (n = 456, 47 %; p < 0.001) and the mean superior impact factor was earned by breast and gynecologic publications (p < 0.01). We identified a consistent and sustained scientific productivity of international IORT expert groups. Most publications appeared in journals with surgical and radiooncological content. The highest impact factor was achieved by medical oncology journals. (orig.)

    Full Text Available The article explores bibliometric features of the Serbian psychology journal Psihologija in the 2001-2012 period. Several basic indicators of the journal’s impact were generated and compared between two periods, before and after 2007 when Psihologija was included in Social Sciences Citation Index (SSCI. Journal’s output was evaluated in regard to other psychology journals included in SSCI in the same year. The results have shown that Psihologija’s impact factor has raised following the increased internationalization of the journal, quantified as the proportion of articles published in English and/or written by foreign authors. However, Psihologija and other South East European (SEE journals still lack a solid international communication network, which is reflected in the absence of related journals and large proportion of citations from local authors.

    Full Text Available Abstract Background The objective of this study was to estimate the research productivity of different world regions in the field of Parasitology. Methods Using the PubMed database we retrieved articles from journals included in the "Parasitology" category of the "Journal Citation Reports" database of the Institute for Scientific Information for the period 1995–2003. Research productivity was evaluated based on a methodology we developed and used in other bibliometric studies by analysing: (1 the total number of publications, (2 the mean impact factor of all papers, and (3 the product of the above two parameters, (4 the research productivity in relation to gross domestic product of each region, and (5 the research productivity in relation to gross national income per capita and population of each region. Results Data on the country of origin of the research was available for 18,110 out of 18,377 articles (98.6% of all articles from the included journals. Western Europe exceeds all world regions in research production for the period studied (34.8% of total articles, with USA ranking second (19.9%, and Latin America & the Caribbean ranking third (17.2%. The mean impact factor in articles published in Parasitology journals was highest for the USA (1.88. Oceania ranked first in research productivity when adjustments for both the gross national income per capita (GNIPC and population were made. Eastern Europe almost tripled the production of articles from only 1.9% of total production in 1995 to 4.3% in 2003. Similarly, Latin America and the Caribbean and Asia doubled their production. However, the absolute and relative production by some developing areas, including Africa, is still very low, despite the fact that parasitic diseases are major public health problems in these areas. Conclusion Our data suggest that more help should be provided by the developed nations to developing areas for improvement of the infrastructure of research.

    There is a recognized challenge in analyzing traditional Chinese medicine formulas because of their complex chemical compositions. The application of modern analytical techniques such as high-performance liquid chromatography coupled with a tandem mass spectrometry has improved the characterization of various compounds from traditional Chinese medicine formulas significantly. This study aims to conduct a bibliometric analysis to recognize the overall trend of high-performance liquid chromatography coupled with tandem mass spectrometry approaches in the analysis of traditional Chinese medicine formulas, its significance and possible underlying interactions between individual herbs in these formulas. Electronic databases were searched systematically, and the identified studies were collected and analyzed using Microsoft Access 2010, Graph Pad 5.0 software and Ucinet software package. 338 publications between 1997 and 2015 were identified, and analyzed in terms of annual growth and accumulated publications, top journals, forms of traditional Chinese medicine preparations and highly studied formulas and single herbs, as well as social network analysis of single herbs. There is a significant increase trend in using high-performance liquid chromatography coupled with tandem mass spectrometry related techniques in analysis of commonly used forms of traditional Chinese medicine formulas in the last 3 years. Stringent quality control is of great significance for the modernization and globalization of traditional Chinese medicine, and this bibliometric analysis provided the first and comprehensive summary within this field.

    This commentary raises significant cautions related to inherent shortcomings in the use of bibliographic analytic technology, and in particular its use in substantive decision making around promotion and tenure. Questions are raised concerning the continued use of scholarly energy for bibliometric analysis of subtly different settings. The recommendation is offered that future efforts in bibliometrics must target methods to reduce methodological shortcomings. These include clarifying the metric used to count sole/multiple authorship, and to evaluate the"merit" of manuscripts as well as journals in which they appear. Finally, the fundamental meaning of the information produced in these analyses (i.e., the validity of the measure) must be clearly presented in order for it to be credibly used.

    Full Text Available This paper examines the martial arts monographs published in Spain between 1906 and 2006 from a bibliometric point of view. Starting from Pérez and Gutiérrez’s previous bibliography (2008, the total number of published monographs following the criteria of subject, decade and the combination of both was analyzed. The results showed a total of 2.036 books (1.285 original editions with a prevalence of Japanese and Chinese martial arts. A group of eight subjects exceeded a hundred volumes (karate, judo/jujutsu, taijiquan, wu-shu/kung fu, classics, qigong, philosophy, history and education, and aikido, with two patterns of bibliographic evolution appearing. The first, represented by Japanese martial arts considered as a group and martial arts focused on the utilitarian and/or sporting performance aspects (judo/jujutsu, karate and wu-shu/kung fu, developed increasingly until the 80’s when it followed a steady-state and/or drop. The second model, which characterises the Chinese martial arts group and martial arts mainly focused on healthy and/or spiritual aspects of training (taijiquan, qigong, aikido, has increased significantly from the 90’s until the present moment. The interpretation of these patterns and the evolution of the martial arts bibliographic production in Spain highlights some aspects such as the development of the Spanish society and sports practice, bibliographic production, reading habits, or the cultural influences of eastern countries on Spain.

    Full Text Available There are several indicators that distinguish an academic discipline, including journals, conferences, and graduate programs. One of them is the presence of academic publications in well-regarded citation indices such as Web of Science (WoS. This study explored the bibliometric characteristics of publications on “second language writing” (SLW covered in the Social Sciences Citation Index and the Arts & Humanities Citation Index of WoS. We found that, while the first appeared in 1992 with a steady increase in recent years, there were a total of 266 SLW publications, mostly in the linguistics research area (92%, in the WoS between 1900 and 2013. The publications included articles, book reviews, and bibliographies written by 1.64 authors per publication, suggesting a low level of collaborations among SLW scholars. They cited 31.44 publications and received citations from 5.90 publications on average. An average SLW title had 2.49 different words and a total of 10.85 words, with an abstract of about five sentences and about six keywords and diverse topics including second language writing, writing, academic writing, error correction, and plagiarism. Our findings will be of value to second language writing scholars, graduate students, and practitioners for examining the status of their field.

    Objectics: The evolution of research activity during the last thirty years on regenerative periodontal surgery is studied. Results: A small number of authors are highly productive with more than 10 publications on the subject each. 79,6% of authors have only produced one article on the subject. The co-authorship average is of 2,68 authors per paper, with a collaboration between 2 and 6 authors. Main journals on the field of regenerative periodontal surgery are Journal of Periodontology and Journal of Clinical Periodontology, which are ranked 14th and 1st in their category according to the Journal Citations Reports. The most used language is English, followed by Japanese and Italian, Spanish occupying the eighth position. Conclusions: A significant increase on scientific literature is observed, similar to the one Dentistry has had. A reduced number of authors account for most production. In the same token, there is a scarce professionalization of researchers in this field, where most of the authors are occasional. On the other hand, there are two very specialized journals on this topic. Key words:Bibliometrics, scientometrics periodontal regeneration, surgical periodontal treatment, scientific literature, scopus, scientific output. PMID:24558535

  9. Analysis of bibliometric indicators for individual scholars in a large data set

    2013-01-01

    Citation numbers and other quantities derived from bibliographic databases are becoming standard tools for the assessment of productivity and impact of research activities. Though widely used, still their statistical properties have not been well established so far. This is especially true in the case of bibliometric indicators aimed at the evaluation of individual scholars, because large-scale data sets are typically difficult to be retrieved. Here, we take advantage of a recently introduced large bibliographic data set, Google Scholar Citations, which collects the entire publication record of individual scholars. We analyze the scientific profile of more than 30,000 researchers, and study the relation between the h-index, the number of publications and the number of citations of individual scientists. While the number of publications of a scientist has a rather weak relation with his/her h-index, we find that the h-index of a scientist is strongly correlated with the number of citations that she/he has rece...

    Over the past two decades, the use of telemedicine as a way to provide medical services has grown as communication technologies advance and patients seek more convenient ways to receive care. Because developments within this field are still rapidly evolving, identifying trends within telemedicine literature is an important task to help delineate future directions of telemedicine research. In this study, we analyzed 7960 telemedicine-related publication records found in the Science Citations Index - Expanded database between 1993 and 2012. Bibliometric analyses revealed that while the total growth in telemedicine literature has been significant in the last twenty years, the publication activity per country and over time has been variable. While the United States led the world in the cumulative number of telemedicine publications, Norway ranked highest when we ordered countries by publications per capita. We also saw that the growth in the number of publications per year has been inconsistent over the past two decades. Our results identified that neuroscience neurology and nursing as two fields of research in telemedicine that have seen considerable growth in interest in this field, and are poised to be the focus of research activity in the near future.

    Phytoremediation is often a low cost alternative to conventional remediation. To assess trends, a bibliometric approach using data from SciVerse Scopus, SciVerseHub, and GoogleTM Trends was used. Globally there is a linear increase in publications containing the word phytoremediation as a percent of all published papers in SciVerse Hub, with China, India, and the Philippines concentrating relatively more research in phytoremediation. Furthermore there was an inverse correlation between a country's Human Development Index (HDI) and a country's phytoremediation research output as a percent of total research. Results show a focus on phytoremediation in countries with low HDI values. This suggests that academic experts are available for advancing phytoremediation applications in countries where the majority of the effected population do not have the education, finances, and political leverage to obtain expensive conventional remediation efforts on their land. Phytoremediation can combine expert advice with affected parties commitment and labor to help mitigate the harms of polluted landscapes.

  12. BIBLIOMETRIC ANALYSIS OF SCIENTIFIC PRODUCTION OF KNOWLEDGE MANAGEMENT AVAILABLE IN SCIELO DATA BASIS IN THE PERIOD OF 1990 TO 2012

    Full Text Available This article aims to characterize the scientific production on "knowledge management", published in Scielo database, from 1999 to 2012, through bibliometric analysis. The methodological procedures, in the first phase, uses predominantly quantitative, descriptive and documentary research, and in a second, a qualitative approach. Considering some limits, it has reached 63 publications, being 3 abstracts of thesis, 1 editorial and 59 articles defined as research sample. The criteria for the analysis are identification of periodic, the years of highest incidence, the number of authors per publication and their scientific production, authors' affiliation, philosophical conception and adopted research strategy. The results point to a methodological inconsistency in the drafting of the articles and a small number of published articles. A high incidence of only one publication per author is observed, showing that the production is more a result of specific work in graduate programs than the reflection and continued studies of the topic. Among other things, we have concluded that the researchers need to invest more in the field in order to expand it.

    The field of pediatric pain research began in the mid-1970s and has undergone significant growth and development in recent years as evidenced by the variety of books, conferences, and journals on the topic and also the number of disciplines engaged in work in this area. Using categorical and bibliometric meta-trend analysis, this study offers a synthesis of research on pediatric pain published between 1975 and 2010 in peer-reviewed journals. Abstracts from 4256 articles, retrieved from Web of Science, were coded across 4 categories: article type, article topic, type and age of participants, and pain stimulus. The affiliation of the first author and number of citations were also gathered. The results suggest a significant increase in the number of publications over the time period investigated, with 96% of the included articles published since 1990 and most research being multiauthored publications in pain-focused journals. First authors were most often from the United States and affiliated with a medical department. Most studies were original research articles; the most frequent topics were pain characterization (39.86%), pain intervention (37.49%), and pain assessment (25.00%). Clinical samples were most frequent, with participants most often characterized as children (6-12 years) or adolescents (13-18 years) experiencing chronic or acute pain. The findings provide a comprehensive overview of contributions in the field of pediatric pain research over 35 years and offers recommendations for future research in the area.

    2004-12-01

    Full Text Available Due to the tremendous increase and variation in serial publications, faculties in department of university are finding it difficult to generate and update their departmental core journal list regularly and accurately, and libraries are finding it difficult to maintain their current serial collection for different departments. Therefore, the evaluation of a departmental core journal list is an important task for departmental faculties and librarians. A departmental core journal list not only helps departments understand research performances of faculties and students, but also helps librarians make decisions about which journals to retain and which to cancel. In this study, a Computer-Aided Bibliometrics System was implemented and two methodologies (JCDF and LibJF were proposed in order to generate a departmental core journal ranking list and make the journal citation analysis. Six departments were taken as examples, with MIS as the major one. One journal citation pattern was found and the ratio of Turning point-to-No. journal was always around 0.07 among the 10 journals and 6 departments. After comparing with four methodologies via overlapping rate and standard deviation distances, the two proposed methodologies were shown to be better than questionnaire and library subscription method.

    The purpose of this study was to identify the 100 top-cited articles in the radiology of trauma, analyze the resulting database to understand factors resulting in highly cited works, and establish trends in trauma imaging. An initial database was created via a Web of Science (WOS) search of all scientific journals using the search terms "trauma" and either "radiology" or a diagnostic modality. Articles were ranked by citation count and screened by two attending radiologists plus a tiebreaker for appropriateness. The following information was collected from each article: WOS all database citations, year, journal, authors, department affiliation, study type and design, sample size, imaging modality, subspecialty, organ, and topic. Citations for the top 100 articles ranged from 82-252, and citations per year ranged from 2.6-37.2. A plurality of articles were published in the 1990s (n = 45) and 1980s (n = 31). Articles were published across 24 journals, most commonly Radiology (n = 31) and Journal of Trauma-Injury, Infection, and Critical Care (n = 28). Articles had an average of five authors and 35 % of first authors were affiliated with a department other than radiology. Forty-six articles had sample sizes of 100 or fewer. Computed tomography (CT) was the most common modality (n = 67), followed by magnetic resonance (MR; n = 22), and X-ray (XR; n = 11). Neuroradiology (n = 48) and abdominal radiology (n = 36) were the most common subspecialties. The 100 top-cited articles in the radiology of trauma are diverse. Subspecialty bibliometric analyses identify the most influential articles of a particular field, providing more implications to clinical radiologists, trainees, researchers, editors, and reviewers than radiology-wide lists.

    Background Triazole antifungal agents play an important role in the treatment of a wide range of fungal infections. Little is known about antifungal triazole drug resistance when compared to antibiotic resistance. Therefore, this study was carried out to give a bibliometric overview of literature on triazole antifungal drug resistance. Methods Keywords related to triazole drug class and resistance were used in a search query in the Scopus search engine. The time span was set from 1980 to 2015. Data pertaining to growth of publications, the most active countries and institutions, the most cited articles, and mapping of molecular mechanisms of resistance were analyzed. Results A total of 1648 journal articles were retrieved with an average of 20.46 citations per article. Annual growth of triazole resistance showed an increasing pattern during the study period. The United States of America (n=446; 27.06%) ranked first in productivity followed by the United Kingdom (UK) (n=176; 10.68%), and China (n=133; 8.07%). Radboud University Nijmegen Medical Centre (n=69, 4.19%) in the Netherlands ranked first in productivity, while the journal Antimicrobial Agents and Chemotherapy ranked first (n=255; 15.47%) in publishing articles on triazole resistance. Mapping mechanisms of resistance showed that efflux pump and mutations in target enzyme are major mechanisms described in resistance to triazoles. Conclusion There was a growth of publications on triazole resistance in the past two decades with the bulk of publications on triazole resistance in Candida species. The data presented here will serve as baseline information for future comparative purposes. PMID:28331838

    AIM To identify and assess the research situation of top 100 cited articles in nonalcoholic fatty liver disease (NAFLD). METHODS The global scientific research articles in the Science Citation Index-Expanded relevant to NAFLD were retrieved and listed according to their citation times from the most to the least. The 100 most frequently cited original articles were selected to systematically evaluate their bibliometric parameters including times cited, publication year, journals, subject categories, and the highly related concepts of NAFLD, which reflected the history and current situation, publication distribution of leading countries and institutes as well as the research hotspots of NAFLD. RESULTS Top 100 cited articles in NAFLD were published from 1965 to 2015 with a citation ranging of 227 to 2151 times since publication, in which the United States was the most predominant country and Mayo Clin was the most productive institution. The majority of the top 100 cited articles were concentrated in SCI subject category of Gastroenterology and Hepatology. Hepatology and Gastroenterology is the top journal that published over half 100 top-cited articles. The significant peak of top cited articles present in the first half of the 2000s while the highest mean number of citation presents in first half of the 1980s. In addition, concepts related to pathology characteristics, epidemiology and medicalization, metabolic syndrome and its combination of symptoms including insulin resistance, biomarkers of lipid metabolism and obesity are listed as the highly related concepts. CONCLUSION The 100 top-cited articles marked with the leading countries, institutions, journals, hotspots and development trend in NAFLD field that could provide the foundation for further investigations.

    Contemporary conservation science benefits from the perspectives of a variety of different disciplines, including a recent synergy with physiology, an interface known as 'conservation physiology'. To evaluate the degree of interaction between conservation and animal/plant physiology, we conducted three bibliometric analyses. We first pursued the use of the term 'conservation physiology' since its first definition in 2006 to determine how frequently it has been used and in which publications. Secondly, we evaluated the occurrence of conservation terms in animal and plant physiology journals, physiological terms in conservation journals, and a combination of terms in ecology journals. Thirdly, we explored trends in a subset of conservation physiology articles published between 2006 and 2012. We identified a surge in the use of the term 'conservation physiology' in 2012, after only a slow increase in usage between 2006 and 2011. Conservation journals tend to have been significantly more active in publishing conservation physiology than animal physiology, plant physiology or ecology journals. However, we found evidence that ecology and animal physiology journals began to incorporate more conservation physiology after 2006, while conservation- and plant physiology-themed journals did not. Among 299 conservation physiology articles that we identified, vertebrate taxa have been over-represented in conservation physiology compared with their relative taxonomic abundance, invertebrate taxa have been under-represented, and plants have been represented in proportion to their relative taxonomic abundance; however, those findings are reasonably consistent with publication trends in conservation biology. Diffuse distribution of conservation physiology papers throughout the literature may have been a barrier to the growth of the subdiscipline when the interface was emerging. The introduction of the focused journal Conservation Physiology in 2013 may address that deficiency

    Nano-energy, the part of nanotechnology dedicated to the study and improvement of the Energy Supply Sector, is a promising and perspective research field. A robust method to quantify international scientific activities in this field is the literature search. An evaluative bibliometric approach applied to the Science Citation Index has been done to retrieve a set of articles related to nano-energy and get knowledge of the direction and trends followed by this particular scientific topic. The resulting database showed an exponential increase of the number of publications issuing nano-based investigations in the energy sector in the last decade, accelerating to an annual growth rate of 1,100%. The most cited articles and the material-clustering protocol revealed that carbon-nanoelements and their application in solar energy harvesting and conversion, and energy storage devices have been principally investigated and represent the main focus in that continuously growing research field. The number of nanotechnology-related papers in the energy database increased monotonically for harvesting, conversion, and storage the last decade, being energy distribution and usage not affected. TiO{sub 2} or SnO{sub 2} nanoparticles or thin films, and nanocomposites occupied the following top positions in the investigated material ranking. This trend was constant along the decade, as confirmed by network analyses. Supported by discipline-clustering, we observed the fundamental character of the research developed between 2000 and 2009, relying mainly on material science and chemistry. Hence, further implementation of nanotechnology findings is needed to stimulate nano-based energy-focused technologies reaching widespread commercial applications.

    The publication of scientific findings is the main way to communicate advances. Our aim was to perform a bibliometric and comparative analysis of the Argentinean gastroenterological research output. We analyzed Argentinean gastroenterological publications selectively retrieved from LILACS (between years 1982-2006) and EMBASE (1996-2007) databases by means of specially constructed filter based on author address and subject headings. The global Argentinean scientific research output is far below that of developed countries and has been affected in direct manner by economic, political and social disturbances in the country. The gastroenterological research output from Argentina represent about 6% of national biomedical research. While 54% belongs to gastroenterology and 46% to hepatology, 65% are based on clinical research and 67% were originally contributions. Only 11% have been published in high impact factor journals. The comparative analysis within countries with health indicators similarities has shown a low biomedical and gastroenterology research output, however, the rate of acceptance at the 18 top gastroenterological journals is acceptable (15%). The contributions of registered specialists were lower for gastroenterologists compared with those from hepatologists (8.7% and 16.4% respectively). The research projects at public hospital funded by the pharmaceutical industry overcome those funded independently. Indeed, it seems that the independent research is being progressively replaced by that supported by the industry due to economic benefits for researchers even when there is a very low participation rate in publications (3%) by Argentinean researchers. We conclude that the Argentinean biomedical and gastroenterological research output is scanty compared with developed countries and countries with comparable health indicators. Our analysis suggests that efforts must be taken to attain objectives directed to develop and improve the Argentinean biomedical and

    BACKGROUND: The monosialoganglioside (GM1) is a popular topic of research but the bibliometric analysis of GM1 over the decades in Science Citation Index-Expanded (SCI-E) remains poorly understood.OBJECTIVE: To identify the global research and to improve the understanding of research trends in the GM1 field from 1942 to 2011. DESIGN: A bibliometric study. DATA RETRIEVAL: We performed a bibliometric analysis based on the SCI-E published by the Institute of Scientific Information. INCLUSIVE CRITERIA: Articles closely related to GM1 were included. Exclusive criteria: (1) Articles related to gangliosidosis, disialo-ganglioside, trisialo-ganglioside or ganglioside GQIb. (2) Document types such as meeting abstracts, reviews, proceedings papers, notes, and letters. MAIN OUTCOME MEASURES: (1) Type of publication output; (2) number of author outputs; (3) distribution of output in subject categories; (4) publication distribution of countries; (5) distribution of output in journals, and (6) distribution of citations in each decade.RESULTS: During 1942 to 2011, there were 10 126 papers on GM1 that were added to the SCI. Articles (8 004) were the most frequently used document type comprising 79.0%, followed by meeting abstracts, reviews and proceedings papers. Research on GM1 could be found in the SCI from 1942, it was developed in the 1970s, greatly increased in the 1980s, and reached a peak in the 1990s, and it was slightly decreased in 2000. The distribution of subject categories showed that GM1 research covered both clinical and basic science research. The USA, Japan, and Germany were the three most productive countries, and the publication numbers in the USA were highest in all decades. The Journal of Biological Chemistry, Journal of Neurochemistry and Biochemistry were core subject journals in GM1 studies in each decade. CONCLUSION: This study highlights the topics in GM1 research that are being published around the world.

    The Korean Journal of Parasitology (KJP) is the official journal of the Korean Society for Parasitology which is celebrating its 50th anniversary in 2009. To assess the contributions and achievements of the KJP, bibliometric analysis was conducted based on the citation data retrieved from 4 major databases; SCI, PubMed, Synapse, and Scopus. It was found that the KJP articles were constantly cited by the articles published in major international journals represented in these databases. More than 60% of 1,370 articles published in the KJP from 1963 to June 2009 were cited at least once by SCI articles. The overall average times cited by SCI articles are 2.6. The rate is almost 3 times higher for the articles published in the last 10 years compared to 1.0 for the articles of the 1960s. The SCI journal impact factor for 2008 is calculated as 0.871. It is increasing and it is expected to increase further with the introduction of the KJP in the database in 2008. The more realistic h-indices were measured from the study data set covering all the citations to the KJP; 17 for SCI, 6 for PubMed, 19 for Synapse, and 17 for Scopus. Synapse extensively picked up the citations to the earlier papers not retrievable from the other 3 databases. It identified many papers published in the 1960s and in the 1980s which have been cited heavily, proving the central role of the KJP in the dissemination of the important research findings over the last 5 decades.

    Reducing nutrition-related health problems in Arab countries requires an understanding of the performance of Arab countries in the field of nutrition and dietetics research. Assessment of research activity from a particular country or region could be achieved through bibliometric analysis. This study was carried out to investigate research activity in "nutrition and dietetics" in Arab countries. Original and review articles published from Arab countries in "nutrition and dietetics" Web of Science category up until 2012 were retrieved and analyzed using the ISI Web of Science database. The total number of documents published in "nutrition and dietetics" category from Arab countries was 2062. This constitutes 1% of worldwide research activity in the field. Annual research productivity showed a significant increase after 2005. Approximately 60% of published documents originated from three Arab countries, particularly Egypt, Kingdom of Saudi Arabia, and Tunisia. However, Kuwait has the highest research productivity per million inhabitants. Main research areas of published documents were in "Food Science/Technology" and "Chemistry" which constituted 75% of published documents compared with 25% for worldwide documents in nutrition and dietetics. A total of 329 (15.96%) nutrition - related diabetes or obesity or cancer documents were published from Arab countries compared with 21% for worldwide published documents. Interest in nutrition and dietetics research is relatively recent in Arab countries. Focus of nutrition research is mainly toward food technology and chemistry with lesser activity toward nutrition-related health research. International cooperation in nutrition research will definitely help Arab researchers in implementing nutrition research that will lead to better national policies regarding nutrition.

    Full Text Available Abstract Background Research in the fields of Preventive Medicine, Occupational/Environmental Medicine, Epidemiology and Public Health play an important role in the advancement of knowledge. In order to map the research production around the world we performed a bibliometric analysis in the above fields. Methods All articles published by different world regions in the above mentioned scientific fields and cited in the Journal Citation Reports (JCR database of the Institute for Scientific Information (ISI during the period 1995 and 2003, were evaluated. The research production of different world regions was adjusted for: a the gross domestic product in 1995 US dollars, and b the population size of each region. Results A total of 48,861 articles were retrieved and categorized. The USA led the research production in all three subcategories. The percentage of articles published by USA researchers was 43%, 44% and 61% in the Preventive Medicine, Epidemiology, and Public Health subcategories, respectively. Canada and Western Europe shared the second position in the first two subcategories, while Oceania researchers ranked second in the field of Public Health. Conclusion USA researchers maintain a leadership position in the production of scientific articles in the fields of Preventive Medicine, Occupational/Environmental Medicine and Epidemiology, at a level similar to other scientific disciplines, while USA contribution to science in the field of Public Health is by all means outstanding. Less developed regions would need to support their researchers in the above fields in order to improve scientific production and advancement of knowledge in their countries.

    Many discussions have enlarged the literature in Bibliometrics since the Hirsch proposal, the so called h-index. Ranking papers according to their citations, this index quantifies a researcher only by its greatest possible number of papers that are cited at least h times. A closed formula for h-index distribution that can be applied for distinct databases is not yet known. In fact, to obtain such distribution, the knowledge of citation distribution of the authors and its specificities are required. Instead of dealing with researchers randomly chosen, here we address different groups based on distinct databases. The first group is composed of physicists and biologists, with data extracted from Institute of Scientific Information (ISI). The second group is composed of computer scientists, in which data were extracted from Google-Scholar system. In this paper, we obtain a general formula for the h-index probability density function (pdf) for groups of authors by using generalized exponentials in the context of escort probability. Our analysis includes the use of several statistical methods to estimate the necessary parameters. Also an exhaustive comparison among the possible candidate distributions are used to describe the way the citations are distributed among authors. The h-index pdf should be used to classify groups of researchers from a quantitative point of view, which is meaningfully interesting to eliminate obscure qualitative methods.

    The discipline of bibliometrics involves the application of mathematical and statistical methods to scholarly publications. The first attempts at systematic data collection were provided by Alfred Lotka and Samuel Bradford, who subsequently established the foundational laws of bibliometrics. Eugene Garfield ushered in the modern era of bibliometrics with the routine use of citation analysis and systematized processing. Key elements of bibliometric analysis include database coverage, consistency and accuracy of the data, data fields, search options, and analysis and use of metrics. A number of bibliometric applications are currently being used in medical science and health care. Bibliometric parameters and indexes may be increasingly used by grant funding sources as measures of research success. Universities may build benchmarking standards from bibliometric data to determine academic achievement through promotion and tenure guidelines in the future. This article reviews the history, definition, laws, and elements of bibliometric principles and provides examples of bibliometric applications to the broader health care community. To accomplish this, the Medline (1966-2014) and Web of Science (1945-2014) databases were searched to identify relevant articles; select articles were also cross-referenced. Articles selected were those that provided background, history, descriptive analysis, and application of bibliometric principles and metrics to medical science and health care. No attempt was made to cover all areas exhaustively; rather, key articles were chosen that illustrate bibliometric concepts and enhance the reader's knowledge. It is important that faculty and researchers understand the limitations and appropriate uses of bibliometric data. Bibliometrics has considerable potential as a research area for health care scientists and practitioners that can be used to discover new information about academic trends, pharmacotherapy, disease, and broader health sciences

    OBJECTIVE: Olfactory ensheathing cell (OEC) transplantation is a promising new approach for the treatment of spinal cord injury (SCI), and an increasing number of scientific publications are devoted to this treatment strategy. This bibliometric analysis was conducted to assess global research trends in OEC transplantation for SCI.DATA SOURCE: All of the data in this study originate from the Web of Science maintained by the Institute for Scientific Information, USA, and includes SCI-EXPANDED, SSCI, A&HCI, CPCI-S, CPCI-SSH, BKCI-S, BKCI-SSH, CCR-EXPANDED and IC. The Institute for Scientific Information's Web of Science was searched using the keywords "olfactory ensheathing cells" or "OECs" or "olfactory ensheathing glia" or "OEG" or "olfactory ensheathing glial cells" or "OEGs" and "spinal cord injury" or "SCI" or "spinal injury" or "spinal transection" for literature published from January 1898 to May 2012.DATA SELECTION: Original articles, reviews, proceedings papers and meeting abstracts, book chapters and editorial materials on OEC transplantation for SCI were included. Simultaneously, unpublished literature and literature for which manual information retrieval was required were excluded.MAIN OUTCOME MEASURES: All selected literatures addressing OEC transplantation for SCI were evaluated in the following aspects: publication year, document type, language, author, institution, times cited, Web of Science category, core source title, countries/territories and funding agency.RESULTS: In the Web of Science published by the Institute for Scientific Information, the earliest literature record was in April, 1995. Four hundred and fourteen publications addressing OEC transplantation for SCI were added to the data library in the past 18 years, with an annually increasing trend. Of 415 records, 405 publications were in English. Two hundred and fifty-nine articles ranked first in the distribution of document type, followed by 141 reviews. Thirty articles and 20 reviews

    Full Text Available We analysed the production, impact factor of, and scientific collaboration involved in viticulture and oenology articles associated with South African research centres published in international journals during the period 1990–2009. The articles under scrutiny were obtained from the Science Citation Index database, accessed via the Web of Knowledge platform. The search strategy employed specific viticulture and oenology terms and was restricted to the field ‘topic’. The results showed that 406 articles were published during the review period, with the most number of publications being in the South African Journal of Enology and Viticulture (n = 34, American Journal of Enology and Viticulture (n = 16 and Journal of Agricultural and Food Chemistry (n = 16. The articles were published by 851 authors from 236 institutions. The collaboration rate was 3.7 authors per article, having grown over the two decades examined. The most productive institutions (i.e. those receiving a greater number of citations were Stellenbosch University (219 published articles and 2592 citations and the Agricultural Research Council (49 published articles and 454 citations, both from South Africa. Graphical representation of co-authorship networks identified 18 groups of authors and a single network of institutions whose core is Stellenbosch University.

    In recent years, there has been increasing interest in the role of intravenous lipid formulations as potential antidotes in patients with severe cardiotoxicity caused by drug toxicity. The aim of this study was to conduct a comprehensive bibliometric analysis of all human and animal studies featuring lipid emulsion as an antidote for the treatment of acute poisoning. The Scopus database search was performed on 5 February 2016 to analyse the research output related to intravenous lipid emulsion as an antidote for the treatment of acute poisoning. Research indicators used for analysis included total number of articles, date (year) of publication, total citations, value of the h-index, document types, countries of publication, journal names, collaboration patterns and institutions. A total of 594 articles were retrieved from Scopus database for the period of 1955-2015. The percentage share of global intravenous lipid emulsion research output showed that research output was 85.86% in 2006-2015 with yearly average growth in this field of 51 articles per year. The USA, United Kingdom (UK), France, Canada, New Zealand, Germany, Australia, China, Turkey and Japan accounted for 449 (75.6%) of all the publications. The total number of citations for all documents was 9,333, with an average of 15.7 citations per document. The h-index of the retrieved documents for lipid emulsion research as antidote for the treatment of acute poisoning was 49. The USA and the UK achieved the highest h-indices, 34 and 14, respectively. New Zealand produced the greatest number of documents with international collaboration (51.9%) followed by Australia (50%) and Canada (41.4%) out of the total number of publications for each country. In summary, we found an increase in the number of publications in the field of lipid emulsion after 2006. The results of this study demonstrate that the majority of publications in the field of lipid emulsion were published by high-income countries. Researchers from

    2010-01-01

    In the analysis of bibliometric networks, researchers often use mapping and clustering techniques in a combined fashion. Typically, however, mapping and clustering techniques that are used together rely on very different ideas and assumptions. We propose a unified approach to mapping and clustering of bibliometric networks. We show that the VOS mapping technique and a weighted and parameterized variant of modularity-based clustering can both be derived from the same underlying principle. We i...

    Full Text Available Open Access of information has had great boom nowadays, meanwhile, some authors don’t want to disseminate their knowledge, making difficult the process mentioned before. Some Databases have being created to answer to this problem. Repositories and scientific magazines are other possibilities that the authors have to diffuse their knowledge. In this work it is made a bibliometric study of the electronic journal INFOCIENCIA during five years in which productivity of articles, the origin of bibliography, quantity of articles by themes and if the bibliography was update or not, were determined, for doing it an analysis of bibliometric character was made. It consisted on summarizing, reviewing, identifying and systematizing the obtained information by means of investigations. The obtained results were: The productivity of article has decreased during these five years, being 2008 the year of less production. The number of biographies varies in the evaluated period. The themes with more quantity of articles were: health, agriculture and education. It was proved that persons consulted more bibliography since 5 to 10 years, followed by the last 5 years.

    Remote sensing was introduced into China in 1970s and then began to flourish. At present, China has developed into a big remote sensing country, and remote sensing is increasingly playing an important role in various fields of national economic construction and social development. Based on China Academic Journals Full-text Database and China Citation Database published by China National Knowledge Infrastructure, this paper analyzed academic characteristics of 963 highly cited papers published by 16 professional and academic journals in the field of surveying and mapping from January 2010 to December 2014 in China, which include hot topics, literature authors, research institutions, and fundations. At the same time, it studied a total of 51,149 keywords published by these 16 journals during the same period. Firstly by keyword selection, keyword normalization, keyword consistency and keyword incorporation, and then by analysis of high frequency keywords, the progress and prospect of China's remote sensing technology in data acquisition, data processing and applications during the past five years were further explored and revealed. It can be seen that: highly cited paper analysis and word frequency analysis is complementary on subject progress analysis; in data acquisition phase, research focus is new civilian remote sensing satellite systems and UAV remote sensing system; research focus of data processing and analysis is multi-source information extraction and classification, laser point cloud data processing, objectoriented high resolution image analysis, SAR data and hyper-spectral image processing, etc.; development trend of remote sensing data processing is quantitative, intelligent, automated, and real-time, and the breadth and depth of remote sensing application is gradually increased; parallel computing, cloud computing and geographic conditions monitoring and census are the new research focuses to be paid attention to.

    Objectives We aimed to examine scholarly collaboration between oral health and prenatal providers. Oral disease is a silent epidemic with significant public health implications for pregnant women. Evidence linking poor oral health during pregnancy to adverse pregnancy and birth outcomes requires oral health and prenatal providers to communicate on the prevention, treatment and co-management matters pertaining to oral health issues among their pregnant patients. The need for inter-professional collaboration is highlighted by guidelines co-endorsed by the American College of Obstetricians and Gynecologists and the American Dental Association, stressing the importance of oral health care during pregnancy. Methods To assess if interdisciplinary communication occurs between oral health and prenatal disciplines, we conducted a network analysis of research on pregnancy-related periodontal disease. Results Social Network analysis allowed us to identify communication patterns between communities of oral health and prenatal professionals via scientific journals. Analysis of networks of citations linking journals in different fields reveals a core-periphery pattern dominated by oral health journals with some participation from medicine journals. However, an analysis of dyadic ties of citation reveals statistically significant "inbreeding" tendencies in the citation patterns: both medical and oral health journals tend to cite their own kind at greater-than-chance levels. Conclusions Despite evidence suggesting that professional collaboration benefits patients' overall health, findings from this research imply that little collaboration occurs between these two professional groups. More collaboration may be useful in addressing women's oral-systemic health concerns that result in adverse pregnancy outcomes.

    Discussion Australian GP publications have shown an impressive growth from 1980 to 2007 with a 15- fold increase. This increase may be due in part to the actions of the Australian government over the past decade to financially support research in primary care, as well as the maturing of academic general practice. This analysis can assist governments, researchers, policy makers and others to target resources so that further developments can be encouraged, supported and monitored.

    Full Text Available Objective: To determine the national and international scientific evidence regarding the use of mirror therapy, as an occupational therapy intervention tool in the clinical setting, in order to acquire knowledge and implement this strategy in professional practice. Materials and methods: A descriptive study was conducted in which the research strategy was held through medical subject headings (MeSH, such as “mirror neuron”, ”occupational therapy”, “physical rehabilitation” and “motor imagery”. Through the use of the bolean and combinations in five different databases were performed: Embase, Ebsco, OTseeker, Science Direct and Medline. The analysis was elaborated by establishing frequencies of different variables such as journal, country, study type and publish­ing year. Conclusions: In the evidence analysis it was found that mirror therapy is an interven­tion modality recently used by different rehabilitation professionals. Since 2004, an increase in the generation of high impact scientific evidence about this subject has been recognized, due in part to the reported effectiveness in clinical practices, mainly the treatment of health conditions secondary to stroke, limb amputations, chronic pain syndromes, and post-surgical rehabilitation. During the reviewed period, an increase in high level academic evidence was observed: 35.7 % of the analyzed publications correspond to randomized controlled trials and 42.9 % are system­atic reviews. The use of mirror therapy in occupational therapy is an intervention modality that facilitates functional rehabilitation processes, promotes independence in performing activities of daily living (adl and allows social participation and environment adaptation processes to happen.

    BACKGROUND: Stroke presents as a transient or chronic brain dysfunction and is associated with high morbidity and high mortality. The doctors and scientists would like to argue how to enhance the validity of the rehabilitation treatment and how to further improve the level of treatment on stroke.OBJECTIVE: The aim of this study was to quantitatively analyze the current worldwide progress in research on stroke rehabilitation treatment based on Web of Science database and ClinicalTrial.gov in the past 10 years.METHODS: We conducted a quantitative analysis of clinical trial articles regarding stroke rehabilitation published in English from 2003 to 2013 and indexed in the National Institutes of Health Clinical Trials registry and Web of Science databases. Data were downloaded on March 15, 2013. RESULTS: (1) From 2003 to 2013, 2 654 clinical trials investigating stroke were indexed in ClinicalTrials.gov. There were only 58 clinical trials registered in 2003, and there was a marked increase from 2005. A total of 605 clinical trials on the rehabilitation of stroke were conducted in the past 10 years. (2) The analysis showed that most of the trials in the field were registered by North American institutions. With respect to the Asian countries, China and Taiwan area of China also published a reasonable proportion of the trials, but comparatively speaking, the number of trials is really rare. Most of the interventions were drugs, followed by the devices, and behavioral interventions were ranked third. (3) In the past 10 years, there were 4 052 studies on stroke indexed by Web of Science database. CONCLUSION: From perspective of research progress, we found that the number of clinical trials and papers on stroke rehabilitation has increased significantly in the past 10 years, between them a remarkable positive correlation exists.

    The purpose of our study was to identify and characterize the 100 most-cited articles in neuroimaging. Based on the database of Journal Citation Reports, we selected 669 journals that were considered as potential outlets for neuroimaging articles. The Web of Science search tools were used to identify the 100 most-cited articles relevant to neuroimaging within the selected journals. The following information was recorded for each article: publication year, journal, category and impact factor of journal, number of citations, number of annual citations, authorship, department, institution, country, article type, imaging technique used, and topic. The 100 most-cited articles in neuroimaging were published between 1980 and 2012, with 1995-2004 producing 69 articles. Citations ranged from 4384 to 673 and annual citations ranged from 313.1 to 24.9. The majority of articles were published in radiology/imaging journals (n=75), originated in the United States (n=58), were original articles (n=63), used MRI as imaging modality (n=85), and dealt with imaging technique (n=45). The Oxford Centre for Functional Magnetic Resonance Imaging of the Brain at John Radcliffe Hospital (n=10) was the leading institutions and Karl J. Friston (n=11) was the most prolific author. Our study presents a detailed list and an analysis of the 100 most-cited articles in the field of neuroimaging, which provides an insight into historical developments and allows for recognition of the important advances in this field.

  10. The bibliometrics of atmospheric environment

    Brimblecombe, Peter; Grossi, Carlota M.

    Bibliometric analysis is an important tool in the management of a journal. SCOPUS output is used to assess the increase in the quantity of material in Atmospheric Environment and stylistic changes in the way authors choose words and punctuation in titles and assemble their reference lists. Citation analysis is used to consider the impact factor of the journal, but perhaps more importantly the way in which it reflects the importance authors give to papers published in Atmospheric Environment. The impact factor of Atmospheric Environment (2.549 for 2007) from the Journal Citation Reports suggests it performs well within the atmospheric sciences, but it conceals the long term value authors place on papers appearing in the journal. Reference lists show that a fifth come through citing papers more than a decade old.

    In bioethics, the first decade of the twenty-first century was characterized by the emergence of interest in the ethical, legal, and social aspects of neuroscience research. At the same time an ongoing extension of the topics and phenomena addressed by neuroscientists was observed alongside its rise as one of the leading disciplines in the biomedical science. One of these phenomena addressed by neuroscientists and moral psychologists was the neural processes involved in moral decision-making. Today both strands of research are often addressed under the label of neuroethics. To understand this development we recalled literature from 1995 to 2012 stored in the Mainz Neuroethics Database (i) to investigate the quantitative development of scientific publications in neuroethics; (ii) to explore changes in the topics of neuroethics research within the defined time interval; (iii) to illustrate the interdependence of different research topics within the neuroethics literature; (iv) to show the development of the distribution of neuroethics research on peer-reviewed journals; and (v) to display the academic background and affiliations of neuroethics researchers. Our analysis exposes that there has been a demonstrative increase of neuroethics research while the issues addressed under this label had mostly been present before the establishment of the field. We show that the research on the ethical, legal and social aspects of neuroscience research is hardly related to neuroscience research on moral decision-making and that the academic backgrounds and affiliations of many neuroethics researchers speak for a very close entanglement of neuroscience and neuroethics. As our article suggests that after more than one decade there still is no dominant agenda for the future of neuroethics research, it calls for more reflection about the theoretical underpinnings and prospects to establish neuroethics as a marked-off research field distinct from neuroscience and the diverse branches

    2016-01-01

    Research on perennial staple crops has increased in the past ten years due to their potential to improve ecosystem services in agricultural systems. However, multiple past breeding efforts as well as research on traditional ratoon systems mean there is already a broad body of literature on perennial crops. In this review, we compare the development of research on perennial staple crops, including wheat, rice, rye, sorghum, and pigeon pea. We utilized the advanced search capabilities of Web of Science, Scopus, ScienceDirect, and Agricola to gather a library of 914 articles published from 1930 to the present. We analyzed the metadata in the entire library and in collections of literature on each crop to understand trends in research and publishing. In addition, we applied topic modeling to the article abstracts, a type of text analysis that identifies frequently co-occurring terms and latent topics. We found: 1.) Research on perennials is increasing overall, but individual crops have each seen periods of heightened interest and research activity; 2.) Specialist journals play an important role in supporting early research efforts. Research often begins within communities of specialists or breeders for the individual crop before transitioning to a more general scientific audience; 3.) Existing perennial agricultural systems and their domesticated crop material, such as ratoon rice systems, can provide a useful foundation for breeding efforts, accelerating the development of truly perennial crops and farming systems; 4.) Primary research is lacking for crops that are produced on a smaller scale globally, such as pigeon pea and sorghum, and on the ecosystem service benefits of perennial agricultural systems.

    Full Text Available BACKGROUND: There exists a lack of knowledge regarding the quantity and quality of scientific yield in relation to individual cancer types. We aimed to measure the proportion, quality and relevance of oncology-related articles, and to relate this output to their associated disease burden. By incorporating the impact factor(IF and Eigenfactor™(EF into our analysis we also assessed the relationship between these indices and the output under study. METHODS: All publications in 2007 were retrieved for the 26 most common cancers. The top 20 journals ranked by IF and EF in general medicine and oncology, and the presence of each malignancy within these titles was analysed. Journals publishing most prolifically on each cancer were identified and their impact assessed. PRINCIPAL FINDINGS: 63260 (PubMed and 126845 (WoS entries were generated, respectively. 26 neoplasms accounted for 25% of total output from the top medical publications. 5 cancers dominated the first quartile of output in the top oncology journals; breast, prostate, lung, and intestinal cancer, and leukaemia. Journals associated with these cancers were associated with much higher IFs and EFs than those journals associated with the other cancer types under study, although these measures were not equivalent across all sub-specialties. In addition, yield on each cancer was related to its disease burden as measured by its incidence and prevalence. CONCLUSIONS: Oncology enjoys disproportionate representation in the more prestigious medical journals. 5 cancers dominate yield, although this attention is justified given their associated disease burden. The commonly used IF and the recently introduced EF do not correlate in the assessment of the preeminent oncology journals, nor at the level of individual malignancies; there is a need to delineate between proxy measures of quality and the relevance of output when assessing its merit. These results raise significant questions regarding the best

    2013-01-01

    Full Text Available Objective: to identify literature and bibliographical evidence regarding, the use of music as a tool during social inclusion processes of people with disabilities; this was done in order to obtain and supply theoretical bases to the project which pertains and arises from the agreement between the Fundación Saldarriaga Concha and the Fundación Nacional Batuta. Materials and methods: as the research strategy implemented during the investigation, “music”, “inclusion” and “disability” with the Boolean AND were used as the search criteria in three different databases: Ebsco, Medline and Lilacs. The analysis was elaborated considering the frequency of different variables/ characteristics of the articles such as, journal, country, type of study and the year it was published. Twenty two articles met the search criteria defined by the authors. Results: the results indicated that the database which contained the most amount of evidence is Ebsco, specifically in the Music Educators Journal, during the years of 2004-2006 40,9% and the majority of articles were published in the United States (81,8%. The most common and frequent type of study found was the subject review (86,4%, mainly incorporating search topics like music-disability. Agreeing with Rumbo, Aranton and García, the level of evidence of the analyzed documents is generally 3, indicating that, above all, the studies tend to be descriptive and based on the opinion of experts. Conclusions: after systematically carrying out the research, it is possible to conclude that the publications which consider the use of music as a tool to facilitate social inclusion processes in children and teenagers, is low. Due to the results obtained, it is strongly suggested that, writers begin to systemize and publish the results evidenced in this field of Occupational Therapy. This paper provides a possible route for future research regarding the topic.

Research on perennials is increasing overall, but individual crops have each seen periods of heightened interest and research activity; 2.) Specialist journals play an important role in supporting early research efforts. Research often begins within communities of specialists or breeders for the individual crop before transitioning to a more general scientific audience; 3.) Existing perennial agricultural systems and their domesticated crop material, such as ratoon rice systems, can provide a useful foundation for breeding efforts, accelerating the development of truly perennial crops and farming systems; 4.) Primary research is lacking for crops that are produced on a smaller scale globally, such as pigeon pea and sorghum, and on the ecosystem service benefits of perennial agricultural systems.

  17. Harmonic allocation of authorship credit: source-level correction of bibliometric bias assures accurate publication and citation analysis.

    Directory of Open Access Journals (Sweden)

    Nils T Hagen

    Full Text Available Authorship credit for multi-authored scientific publications is routinely allocated either by issuing full publication credit repeatedly to all coauthors, or by dividing one credit equally among all coauthors. The ensuing inflationary and equalizing biases distort derived bibliometric measures of merit by systematically benefiting secondary authors at the expense of primary authors. Here I show how harmonic counting, which allocates credit according to authorship rank and the number of coauthors, provides simultaneous source-level correction for both biases as well as accommodating further decoding of byline information. I also demonstrate large and erratic effects of counting bias on the original h-index, and show how the harmonic version of the h-index provides unbiased bibliometric ranking of scientific merit while retaining the original's essential simplicity, transparency and intended fairness. Harmonic decoding of byline information resolves the conundrum of authorship credit allocation by providing a simple recipe for source-level correction of inflationary and equalizing bias. Harmonic counting could also offer unrivalled accuracy in automated assessments of scientific productivity, impact and achievement.

    Full Text Available The aim of this article is to assess the democratization process in Africa in general and the multi-party elections in particular. The decolonization process in Africa (1960s and 1970s, which was known as the “first liberation” completed by the emergence of many, new independent African countries. In most of the newly liberated countries the political parties that led the anti-colonial struggle established one-party domination after independence. The rapid democratization process (“second liberation” in Africa began in the first half of the 1990s, particularly with Benin’s multiparty election in 1991. In this period, multi-party elections had taken place in most of African countries. These transitions led to “limited” democracies, characterized by a lack of liberal freedoms, low levels of popular involvement (except at election times, narrow range of civil liberties and the concentration of political power in the hands of small elite groups. Holding an election is a milestone, but it is not the key to Africa’s democratic legitimacy. Many elections in the African region have failed to meet the internationally accepted standards for free and fair elections. Though Africa’s record on free and fair elections is mixed, at present, most of Africans have embraced elections as indispensable mechanism for determining their future course.

    Many discussions have enlarged the literature in Bibliometrics since the Hirsh proposal, the so called $h$-index. Ranking papers according to their citations, this index quantifies a researcher only by its greatest possible number of papers that are cited at least $h$ times. A closed formula for $h$-index distribution that can be applied for distinct databases is not yet known. In fact, to obtain such distribution, the knowledge of citation distribution of the authors and its specificities are required. Instead of dealing with researchers randomly chosen, here we address different groups based on distinct databases. The first group is composed by physicists and biologists, with data extracted from Institute of Scientific Information (ISI). The second group composed by computer scientists, which data were extracted from Google-Scholar system. In this paper, we obtain a general formula for the $h$-index probability density function (pdf) for groups of authors by using generalized exponentials in the context of ...

    This paper introduces a bibliometric, citation network-based method for assessing the social validation of novel research, and applies this method to the development of high-throughput toxicology research at the US Environmental Protection Agency. Social validation refers to the acceptance of novel research methods by a relevant scientific community; it is formally independent of the technical validation of methods, and is frequently studied in history, philosophy, and social studies of science using qualitative methods. The quantitative methods introduced here find that high-throughput toxicology methods are spread throughout a large and well-connected research community, which suggests high social validation. Further assessment of social validation involving mixed qualitative and quantitative methods are discussed in the conclusion.

    As federal programs are held more accountable for their research investments, The National Institute of Environmental Health Sciences (NIEHS) has developed a new method to quantify the impact of our funded research on the scientific and broader communities. In this article we review traditional bibliometric analyses, address challenges associated with them, and describe a new bibliometric analysis method, the Automated Research Impact Assessment (ARIA). ARIA taps into a resource that has only rarely been used for bibliometric analyses: references cited in "important" research artifacts, such as policies, regulations, clinical guidelines, and expert panel reports. The approach includes new statistics that science managers can use to benchmark contributions to research by funding source. This new method provides the ability to conduct automated impact analyses of federal research that can be incorporated in program evaluations. We apply this method to several case studies to examine the impact of NIEHS funded research.

    Background The objective of this study was to analyze the trend in the publication of systematic reviews on hip fractures through a bibliometric approach.Methods Literature including systematic reviews or meta-analyses on hip fractures was searched from the ISI Web of Science citation database.The search results were analyzed in terms of geographical authorship and frequency of citation by country,institution,author,and periodical distribution.Results A total of 654 published systematic reviews from 1995 to 2013 in 48 countries or regions were retrieved.The United States (171) was the predominant country in terms of the number of total publications,followed by the United Kingdom (149),Canada (120),Australia (76),and China (54).The number of systematic reviews significantly increased during the last 6 years,especially in China.The production ranking changed in 2012,at which time the United States and China were the leaders in the yearly production of systematic reviews on hip fractures.The amount of literature (27 publications) from China contributed almost one-quarter of the total literature (109 publications) in 2012.However,the average number of citations of each article from China was still low (6.70),while the highest number of citations of each article was from Sweden (193.36).The references were published in 239 different journals,with 15 journals contributing to 41.3% of the systematic reviews on hip fractures.The two journals that contributed the most were Osteoporosis International (10.6%) and the Cochrane Database of Systematic Reviews (7.6%).The predominant institution in terms of the number of publications was McMaster University (36) in Canada.Conclusions The best evidence in the field of hip fractures has attracted increasing attention.Systematic reviews on hip fractures from China have been increasingly more frequent during the past 6 years,particularly in 2012.

  16. A unified approach to mapping and clustering of bibliometric networks

    Waltman, Ludo; Noyons, Ed C M

    2010-01-01

    In the analysis of bibliometric networks, researchers often use mapping and clustering techniques in a combined fashion. Typically, however, mapping and clustering techniques that are used together rely on very different ideas and assumptions. We propose a unified approach to mapping and clustering of bibliometric networks. We show that the VOS mapping technique and a weighted and parameterized variant of modularity-based clustering can both be derived from the same underlying principle. We illustrate our proposed approach by producing a combined mapping and clustering of the most frequently cited publications that appeared in the field of information science in the period 1999-2008.

    Bach, Jean-François

    2011-06-01

    Quantitative analysis of publications and their citations, a procedure known as bibliometrics, has become increasingly important in the evaluation of scientists and clinicians. In the clinical setting, bibliometrics is used for the calculation of hospital budgets. While bibliometrics is attractive because it rapidly provides numbers that bear a certain relation to scientific productivity, it is often misused. The parameters chosen are questionable and sometimes worthless because of material errors or inappropriate use. More importantly, reducing the activity of a scientist or physician simply to the number of his or her publications or citations, without analyzing the importance and impact of the work itself can lead to serious errors.

    Bibliometric studies typically focus on citation and publication analysis. Due to recent advances in web technology along with greater access to web content, bibliometric research can include statistics and measures that were once difficult to obtain. The European Southern Observatory's Telescope Bibliography (ESO telbib), a content management system for refereed articles containing ESO data, provides an excellent test-bed for exploring next generation bibliometrics. Through web services provided by the NASA Astrophysics Data System (ADS) Abstract Service among others, previously unavailable information can be imported into telbib where it can be analyzed in further detail. Though some telbib features are still in their infancy, some interesting trends can already be derived.

  14. Comparative financial analysis of electricity utilities in West Africa

    Energy Technology Data Exchange (ETDEWEB)

    Fritsch, Remi, E-mail: fritschr@afd.fr [Centre d' Etudes Financieres, Economiques et Bancaires (CEFEB), BP 33401, 13567 Marseille cedex 02 (France)

    2011-10-15

    Access to electricity is a major issue in West Africa. Governments have a difficult equation to solve. They naturally seek to offer their people a cheap kWh. But they are constrained by a production based largely on oil and therefore highly volatile production costs. How to fix an acceptable tariff, taking into account the investment needs required to expand the network and increase production? This analysis should provide some answers. The study presented in this paper provides a financial analysis of electricity utilities in West Africa. It allows a comparison of performances on a number of key financial ratios related to operations (Earning Before Interest Taxes Debt and Amortization/sales, working capital requirement/sales, days of receivables or payables), investment (net fixed assets/gross fixed assets), bank financing (financial structure, debt/EBITDA, interest expense/EBITDA) and economic and financial returns (Return On Capital Employed, Return On Equity). The conclusion focuses on the growth opportunity that the electricity sector could represent for each country. But this opportunity may only materialize if the EBITDA margins are restored. The available options appear limited and must be assessed taking into account the context of each country: tariff increase, improvement of technical losses or diversification into means of production no longer based primarily on oil or gas. - Highlights: > The study provides a financial analysis of electricity distribution companies in West Africa. > The study highlights generally insufficient EBITDA margins. > The study raises the question of tariffs and contribution to Gross Domestic Product of the electricity sector. > The conclusion focuses on the growth opportunity that the electricity sector could represent for each country.

  20. Bibliometric indicators: quality measurements of scientific publication.

    Science.gov (United States)

    Durieux, Valérie; Gevenois, Pierre Alain

    2010-05-01

    Bibliometrics is a set of mathematical and statistical methods used to analyze and measure the quantity and quality of books, articles, and other forms of publications. There are three types of bibliometric indicators: quantity indicators, which measure the productivity of a particular researcher; quality indicators, which measure the quality (or "performance") of a researcher's output; and structural indicators, which measure connections between publications, authors, and areas of research. Bibliometric indicators are especially important for researchers and organizations, as these measurements are often used in funding decisions, appointments, and promotions of researchers. As more and more scientific discoveries occur and published research results are read and then quoted by other researchers, bibliometric indicators are becoming increasingly important. This article provides an overview of the currently used bibliometric indicators and summarizes the critical elements and characteristics one should be aware of when evaluating the quantity and quality of scientific output.

    AIM To investigate diabetic retinopathy (DR) literature using the Institute for Scientific Information (ISI) Web of Science (WoS) database and to analyse the correlation results between socio-economic development datas and number of DR publications. METHODS The statistical analysis of the documents published during 1980-2014 was analysed. The data of this study were based on the database of WoS. “Diabetic retinopathy” was used as the keywords to search the WoS database. RESULTS The United States ranked first in the DR research with 1840 publications and 24.38% of the world production followed by England and Japan. Besides, the most productive country was Iceland. A high correlation was found between number of publications and 2014 gross domestic product (GDP) values of 81 countries (r=0.800, P<0.001). We found a significant correlation between number of publications and Human Development Index (HDI) (r=0.645, P=0.001). There is a moderate correlation between people with diabetes and number of DR publications for 81 countries (r=0.514, P<0.01). It could be analysed that estimated publication number with DR title will be 445 according to the regression curve constituted with cubic model in 2015 (R2=1.000). CONCLUSION More DR studies have been published in developed countries, DR and other complications of diabetes have gradually increased in developing countries over recent decades. It can be expected that the number of DR studies will gradually increase in developing countries. PMID:27990373

    Full Text Available Background: Bibliometric or scientometric studies are methodological fields focused on the structural analysis of the information contained in scientific publication and generate indicators that help identify challenges and achievements in research. We aimed to characterize the publications that used this method authored by medical students in Latin America. Methods: We reviewed articles that performed a bibliometric analysis and were published in a Latin American medical student journal, between 2001 and 2012. We analyzed the characteristics of the articles, authors and references. Linear simple regression and Pearson correlation coefficient (PCC were developed to identify trends and correlations with 95% confidence. Results: There were 12 volumes of the journal available online, with a total of 236 articles. Of these, 13 (5.5% were bibliometric studies: five original articles, four letters to the editor, two editorials, one short communication, and one review. There was a positive significant relationship between time (years and number of publications (ß1=0.16, p=0.03, PCC=63%, and citations of each article (not significant, ß1=1.3, p=0.09, PCC=49%. Conclusion: There was an increase in the number of bibliometric publications after 2008, possibly influenced by a popularization of these types of studies in Latin America. Findings should motivate new and collaborative studies in this field. Moreover, it will be necessary to clarify publication areas of interest of medical students around the world.

  3. Sampling Issues in Bibliometric Analysis

    CERN Document Server

    Williams, Richard

    2014-01-01

    Bibliometricians face several issues when drawing and analyzing samples of citation records for their research. Drawing samples that are too small may make it difficult or impossible for studies to achieve their goals, while drawing samples that are too large may drain resources that could be better used for other purposes. This paper considers three common situations and offers advice for dealing with each. First, an entire population of records is available for an institution. We argue that, even though all records have been collected, the use of inferential statistics and significance testing is both common and desirable. Second, because of limited resources or other factors, a sample of records needs to be drawn. We demonstrate how power analyses can be used to determine in advance how large the sample needs to be to achieve the study's goals. Third, the sample size may already be determined, either because the data have already been collected or because resources are limited. We show how power analyses c...

  4. Bibliometrics and research evaluation uses and abuses

    CERN Document Server

    Gingras, Yves

    2016-01-01

    The research evaluation market is booming. "Ranking," "metrics," "h-index," and "impact factors" are reigning buzzwords. Government and research administrators want to evaluate everything -- teachers, professors, training programs, universities -- using quantitative indicators. Among the tools used to measure "research excellence," bibliometrics -- aggregate data on publications and citations -- has become dominant. Bibliometrics is hailed as an "objective" measure of research quality, a quantitative measure more useful than "subjective" and intuitive evaluation methods such as peer review that have been used since scientific papers were first published in the seventeenth century. In this book, Yves Gingras offers a spirited argument against an unquestioning reliance on bibliometrics as an indicator of research quality. Gingras shows that bibliometric rankings have no real scientific validity, rarely measuring what they pretend to. Although the study of publication and citation patterns, at the proper scales...

    The data for the Ebola outbreak that occurred in 2014-2016 in three countries of West Africa are analysed within a common framework. The analysis is made using the results of an agent based Susceptible-Infected-Removed (SIR) model on a Euclidean network, where nodes at a distance $l$ are connected with probability $P(l) \\propto l^{-\\delta }$ in addition to nearest neighbors. The cumulative density of infected population here has the form $R(t) = \\frac{a\\exp(t/T)}{1+c\\exp(t/T)}$, where the parameters depend on $\\delta$ and the infection probability $q$. This form is seen to fit well with the data. Using the best fitting parameters, the time at which the peak is reached is estimated and is shown to be consistent with the data. We also show that in the Euclidean model, one can choose $\\delta$ and $q$ values which reproduce the data for the three countries qualitatively. These choices are correlated with population density, control schemes and other factors.

    The data for the Ebola outbreak that occurred in 2014–2016 in three countries of West Africa are analysed within a common framework. The analysis is made using the results of an agent based Susceptible-Infected-Removed (SIR) model on a Euclidean network, where nodes at a distance l are connected with probability P(l) ∝ l‑δ, δ determining the range of the interaction, in addition to nearest neighbors. The cumulative (total) density of infected population here has the form , where the parameters depend on δ and the infection probability q. This form is seen to fit well with the data. Using the best fitting parameters, the time at which the peak is reached is estimated and is shown to be consistent with the data. We also show that in the Euclidean model, one can choose δ and q values which reproduce the data for the three countries qualitatively. These choices are correlated with population density, control schemes and other factors. Comparing the real data and the results from the model one can also estimate the size of the actual population susceptible to the disease. Rescaling the real data a reasonably good quantitative agreement with the simulation results is obtained.

    Full Text Available In this systematic review, we estimate the prevalence of six types of arthritis in Africa; namely rheumatoid arthritis, osteoarthritis, juvenile arthritis, psoriatic arthritis, gout, and ankylosing spondylitis.We comprehensively searched literature on 31 August 2014 in MEDLINE, EMBASE, Web of Science and the Cochrane Library to identify eligible studies from 1975 up to 31 July 2014. Two review authors independently selected studies, extracted data, and appraised studies. We carried out random effects meta-analysis of prevalence of arthritis and assessed heterogeneity through subgroup analyses. We performed separate analyses for population- and hospital-based studies, as well as rural and urban settings.We included 27 cross-sectional studies (20 population-based and 7 hospital-based from Africa reporting on the prevalence of arthritis. The majority of the studies were from South Africa (44.4%, 12/27. Rheumatoid arthritis in urban settings ranged from 0.1% in Algeria, 0.6% in the DRC, to a meta-analysis overall prevalence of 2.5% in South Africa, and in rural settings ranged from a meta-analysis overall prevalence of 0.07% in South Africa, 0.3% in Egypt, to 0.4% in Lesotho. Osteoarthritis was the most prevalent form of arthritis and in urban settings it was 55.1% in South Africa and in rural settings, all in South Africa, ranged from 29.5%, 29.7%, up to 82.7% among adults aged over 65 years. Other results include highest prevalence of 33.1% for knee osteoarthritis in rural South Africa, 0.1% for ankylosing spondylitis in rural South Africa, 4.4% for psoriatic arthritis in urban South Africa, 0.7% for gout in urban South Africa, and 0.3% for juvenile idiopathic arthritis in urban Egypt. A third of the included studies had a low risk of bias (33.3%, 9/27, 40.8% (11/27 moderate risk, and 25.9% (7/27 had a high risk of bias.In this systematic review, we have identified the paucity of latest prevalence data on arthritis in Africa.

    with information on Latin American systematics: Biosis, CAB, Periódica, SCI, Scopus and Zoological Record. The databases are characterized and compared considering their content, temporal, typological, geographical, thematical coverage, kind of access and new taxon description, to identify which and how many should be used to be more representative. Of the 1363 journals analyzed, 36.5% are found in more than one database and 63.46% are recorded in a single one. Zoologial Record contains 63421 documents, Biosis 19079, CAB 14363, Periódica 11185, SCI 3257 and Scopus 916. CAB and ZR are the oldest databases, the average number of articles published per year was 6417 for Biosis, 433 for ZR, 361 for Periódica, 145 for CAB, 91 for SCI and 30 for Scopus. According to the network analysis, there are stronger relations between SCI and Biosis, which share at least 16% of titles, CAB and Biosis share 15%, Biosis and ZR 14%, and CAB and ZR 11%. Based on the cladogram obtained from a parsimony analysis on the shared journals, the strongest relation is between Biosis and SCI; Periódica has the largest number of exclusive journals with 285. ZR has 72.9% of published articles with descriptions of new taxa and an average of 322 a year, CAB 54.6% with 82, and Periódica 24.6% with 90. None of databases meets the characteristics to be used as a single source of information, therefore it would be appropriate to use different combinations according to the aim of the analysis. Biosis has the most comprehensive information on any current taxon, Zoological Record and CAB have a broader temporal coverage and include mainly animals or plants, respectively. SCI has the largest number of documents in mainstream journals, with references, citations and bibliometric indicators. Periódica has the largest number of documents and temporal coverage published in the area. The cladogram proved to be an optimal visualization tool to represent the main features of each data base.

  13. Bibliometric study of the reverse salient concept

    Full Text Available In the development of technological systems the focus of system analysis is often on the sub-system that delivers insufficient performance – i.e. the reverse salient – which subsequently limits the performance of the system in its entirety. The reverse salient is therefore a useful concept in the study of technological systems and while the literature holds numerous accounts of its use, it is not known how often, in which streams of literature, and in what type of application the concept has been utilized by scholars since its introduction by Thomas Hughes in 1983. In this paper we employ bibliometric citation analysis between 1983 and 2008, inclusively, to study the impact of the reverse salient concept in the literature at large as well as study the dissemination of the concept into different fields of research. The study results show continuously growing number of concept citations in the literature over time as well as increasing concept diffusion into different research areas. The analysis of article contents additionally suggests the opportunity for scholars to engage in deeper conceptual application. Finally, the continuing increase in the number of citations highlights the importance of the reverse salient concept to scholars and practitioners.

    When we help an author publish a book or journal article, is that the end of the job? Viewed in the aggregate, a company's publications represent one of its greatest business assets. Can professionals in the information and communication fields help their company understand the return on its investment in publishing? The field of bibliometrics studies publication patterns by using quantitative analysis and statistics. Bibliometrics can be either descriptive, such as looking at how many articles your organization has published, or evaluative, such as using citation analysis to look at how those articles influenced subsequent research by others. Counting publications can be useful for doing some comparisons, but citation analysis allows you to look at the impact those articles have had on others by determining how often they are cited. Citation analysis can also show what journals, organizations, and even countries have high impact in different fields of research. The Institute for Scientific Information (ISI) has been a leader in the citation analysis field since 1961, when ISI published the first Science Citation Index. Pacific Northwest National Laboratory has been using data from ISI for both descriptive and evaluative purposes. This data is used to track what the researchers at the Laboratory are writing and then comparing research groups within the organization over a period of years to identify trends and opportunities. PNNL has also used citation analysis to explore what organizations and academic institutions are doing research in certain fields for partnering opportunities. We have realized that the electronic system PNNL uses to approve and track its publications contains very valuable bibliometric data that can be used to make decisions about business directions for the company.

    This bibliometric study of a large publication set dealing with research on climate change aims at mapping the relevant literature from a bibliometric perspective and presents a multitude of quantitative data: (1) The growth of the overall publication output as well as (2) of some major subfields, (3) the contributing journals and countries as well as their citation impact, and (4) a title word analysis aiming to illustrate the time evolution and relative importance of specific research topics. The study is based on 222,060 papers (articles and reviews only) published between 1980 and 2014. The total number of papers shows a strong increase with a doubling every 5-6 years. Continental biomass related research is the major subfield, closely followed by climate modeling. Research dealing with adaptation, mitigation, risks, and vulnerability of global warming is comparatively small, but their share of papers increased exponentially since 2005. Research on vulnerability and on adaptation published the largest proportion of very important papers (in terms of citation impact). Climate change research has become an issue also for disciplines beyond the natural sciences. The categories Engineering and Social Sciences show the strongest field-specific relative increase. The Journal of Geophysical Research, the Journal of Climate, the Geophysical Research Letters, and Climatic Change appear at the top positions in terms of the total number of papers published. Research on climate change is quantitatively dominated by the USA, followed by the UK, Germany, and Canada. The citation-based indicators exhibit consistently that the UK has produced the largest proportion of high impact papers compared to the other countries (having published more than 10,000 papers). Also, Switzerland, Denmark and also The Netherlands (with a publication output between around 3,000 and 6,000 papers) perform top-the impact of their contributions is on a high level.

    literatures were published before December 31,2013,the bibliometric analysis was conducted to analyze the aspects of year distribution,countries and regional distribution,journal distribution and high-frequency words distribution. Results The domestic studies on workplace violence in hospital were behind inter-national studies for about 16 years. The numbers of the published domestic and foreign literatures were kept in stable growth trend with average growth rate of 33. 7% and 8. 6% per year from 2003 to 2012,respectively. The leading five countries included the United States,Australia,Britain,Canada and Turkey which published more literatures related to workplace violence in hospital. The proportion of the literatures on workplace violence in hospital in all workplace violence related literatures in China was higher than that in foreign literatures[87. 7%(199/227)vs 68. 3%(1 194/1 749),P<0. 01 ]. Most of the domestic and foreign literatures were published on journals which focused on nurse or nursing subjects. The high frequency keywords related to the workplace violence in hospitals were different between domestic literatures and foreign literatures. In domestic literatures,there was lack of occupational health,environment,data collection and key-words representing violence,such as aggression or bullying or aggressive behavior. Conclusion There is no clear defini-tion of workplace violence in hospitals and lack of regulations and standards to prevent and control them in China,which is still not brought into the research and management of occupational health and safety. Researches about workplace violence in hospitals are synchronized with the reform of medical system in China,which reminds us workplace violence in hospital might be associated with policy and social environment and the health reform.

    Full Text Available The social network analysis involves social and behavioral science. The decentralization of productive activities, such as the formation of "network organizations" as a result of downsizing of large corporate structures of the past, marked by outsoucing and formation of alliances, shows the importance of this theme. The main objective of this paper is to analyze the theory of cooperation and social networks over a period of 24 years. For this, was performed a bibliometric study with content analysis. The database chosen for the initial sample search was ISI Web of Science. The search topics were “social network” and “cooperation”. Were analyzed 97 articles and their references, through networks of citations. The main identified research groups dealing with issues related to trust, strategic alliances, natural cooperation, game theory, social capital, intensity of interaction, reciprocity and innovation. It was found that the publications occurred in a large number of journals, which indicates that the theme is multidisciplinary, and only five journals published at least three articles. Although the first publication has occurred in 1987, was from 2006 that the publications effectively increased. The areas most related to the theme of the research were performance, evolution, management, graphics, model and game theory.

    Daily accumulated precipitation time series from satellite retrieval algorithms (e.g., ARC2 and TAMSAT) are exploited to extract the spatial and temporal variability of East Africa (EA - 5°S-20°N, 28°E-52°E) precipitation during last decades (1983-2013). The Empirical Orthogonal Function (EOF) analysis is applied to precipitation time series to investigate the spatial and temporal variability in particular for October-November-December referred to as the short rain season. Moreover, the connection among EA's precipitation, sea surface temperature, and soil moisture is analyzed through the correlation with the dominant EOF modes of variability. Preliminary results concern the first two EOF's modes for the ARC2 data set. EOF1 is characterized by an inter-annual variability and a positive correlation between precipitation and El Niño, positive Indian Ocean Dipole mode, and soil moisture, while EOF2 shows a dipole structure of spatial variability associated with a longer scale temporal variability. This second dominant mode is mostly linked to sea surface temperature variations in the North Atlantic Ocean. Further analyses are carried out by computing the time series of the joint CCI/CLIVAR/JCOMM Expert Team on Climate Change Detection and Indices (ETCCDI, http://etccdi.pacificclimate.org/index.shtml), i.e. RX1day, RX5day, CDD, CDD, CWD, SDII, PRCPTOT, R10, R20. The purpose is to identify the occurrenes of extreme events (droughts and floods) and extract precipitation temporal variation by trend analysis (Mann-Kendall technique). Results for the ARC2 data set demonstrate the existence of a dipole spatial pattern in the linear trend of the time series of PRCPTOT (annual precipitation considering days with a rain rate > 1 mm) and SDII (average precipitation on wet days over a year). A negative trend is mainly present over West Ethiopia and Sudan, whereas a positive trend is exhibited over East Ethiopia and Somalia. CDD (maximum number of consecutive dry days) and

    As one of the most vulnerable regions to climate change, West Africa (WA) has since the 1970s suffered sustained reduction in rainfall amounts, leading to droughts and associated negative impacts on its water resources. Although rainfall rates have been reported to have experienced a degree of recovery, dry conditions persist. Additionally, the region faces perennial flooding, thus resulting in a highly variable hydrologic regime due to the extreme climate conditions. This therefore necessitates routine monitoring of the WA's freshwater reserves and its response to climate variations at the short and long term scales to aid sustainable use and management. However, this monitoring is hampered by data deficiency issues within the region. Consequently, dynamics leading to changes in water availability over the region are not completely understood. In this work, the recent flux and state of freshwater availability over WA from 1979 to 2013 is assessed by investigating the coupled variability of GRACE-derived terrestrial water storage (TWS) and its changes (TWSC) estimates with rainfall, evapotranspiration, and land surface air temperature (LSAT), as well as, major global and regional teleconnection indices using complex principal component analysis and wavelet transforms. Since GRACE covers a relatively short period, and thereby present challenges for long to medium term analyses, Artificial Neural Network (ANN) is employed to extend the GRACE series to 1979. The results from the ANN proved to be robust upon evaluation; spatially-averaged series for major basins and sub-climatic zones, as well as, the whole of WA presented RMSE, Nash-Sutcliffe efficient, and coefficient of determination (R2) of 11.83 mm, 0.76 and 0.89 respectively. Overall, the results obtained from this study indicate that, sustained increase in water flux, in terms of TWSC, contributed to a resurgence in freshwater reserves in the 21st century over WA from the low levels in the late 20th century

    Full Text Available Objective – To explore the characteristics and distribution of randomized controlled trials (RCTs in the medical literature. The study aims to identify the growth patterns of the RCT, key subject matter, country and language of publication, and determine a list of core journals which contain a substantial proportion of the RCT literature. Design – Retrospective analysis of RCTs. Setting – Medical journal literature. Subjects – A total of 160,213 articles published between 1965‐2001. Detailed analysis of a subset numbering 114,850 articles published from 1990‐2001. Methods – The study seeks to identify all RCTs in MEDLINE from 1965‐2001, and examines the growth rate of the RCT. The authors then do a more detailed analysis on a subset of data from 1990‐2001, using Access database and Excel spreadsheet software, and PERL programming language. The references were analyzed by five fields within MEDLINE; publication type, source, language, country of publication, and descriptor (subject index. Main results – An exponential growth rate for the RCT is demonstrated, suggesting that in the medical literature development has not yet matured and that research using this method continues to grow. A growth rate for the RCT of 11.2% per annum is identified. The most common form of publication is the journal article, making up approximately 98% of the RCT literature. Approximately 75% of the RCTs are multicentre trials indicating that this is the design of choice adopted by researchers. The United States proves to be the greatest source of RCT literature, with 39.9% of journals and 50.6% of articles originating there. After the USA, the most productive countries are England (15.8% of journals and 21.7% articles and Germany (6.5% journals and 6.1% articles. As might be expected, English is the predominant language providing 92.9% of the total publications. Of the remaining 7%, German is the most common language accounting for 2.2%. The top

    This paper is an overview of hailpad research from its origin until today using as a search criterion the bibliographic references on the subject in the Web of Science database (ISI). The search was carried out on 1st September 2008. Among the more than 3·10 7 scientific documents included in the Science Citation Index Expanded (SCI-EXPANDED) from 1945 to the present, the search engine identified 41 containing the word "hailpad*" (the asterisk is a wildcard for any letter or group of letters). The results have been analyzed according to various criteria: countries with hailpad networks or studies on hailpads; date of the first article; evolution of the number of articles per decade; concepts studied and research lines followed in each article; and finally, a bibliometric analysis of the journals where these articles have been published. It was found that 70% of the articles on hailpads were published in 2 journals: Journal of Applied Meteorology and Atmospheric Research. These two journals also concentrate most of the citations. The number of articles on hailpads and the documents that cite them have grown steadily, and it is expected to grow still further in the present decade if we take into account the trends found.

    Ito, Takahiko; Shimbo, Masashi; Kudo, Taku; Matsumoto, Yuji

    The application of kernel methods to citation analysis is explored. We show that a family of kernels on graphs provides a unified perspective on the three bibliometric measures that have been discussed independently: relatedness between documents, global importance of individual documents, and importance of documents relative to one or more (root) documents (relative importance). The framework provided by the kernels establishes relative importance as an intermediate between relatedness and global importance, in which the degree of `relativity,' or the bias between relatedness and importance, is naturally controlled by a parameter characterizing individual kernels in the family.

    Full Text Available This paper compares the research and publication patterns of academic librarians in eastern and southern Africa. The study confined its scope to publications produced between 1990 and 2006. Bibliometric techniques through content analysis were used as a research method. Two online databases, namely LISTA and WORLDCAT were used for publication searches. Names of academic librarians were retrieved from their respective academic library websites and used as keywords for retrieving data from the two online databases. A total of 866 academic librarians, i.e. 755 from southern Africa and 111 from eastern Africa, were identified and their research publication records analysed. The results indicate that in terms of publications per librarian there was no significant difference between southern Africa and eastern Africa; South Africa was the most productive country in terms of publications; the University of Botswana Library was the most prolific library; Muswazi from the University of Witwatersrand and Pienaar from the University of Pretoria were the most productive academic librarians; academic librarians in eastern Africa preferred publishing in foreign journals while those from southern Africa published more in domestic journals led by South African Journal of Libraries and Information Science; the publication output of the two regions was inconsistent (up-down trend during this period; the main subject area of librarians in both regions was Information Technology; most academic librarians from both regions preferred publishing individually; and the most published type of document in both regions was journal articles.

    Database tomography (DT) is a textual database analysis system consisting of two major components: (1) algorithms for extracting multiword phrase frequencies and phrase proximities (physical closeness of the multiword technical phrases) from any type of large textual database, to augment (2) interpretative capabilities of the expert human analyst. DT was used to derive technical intelligence from a fullerenes database derived from the Science Citation Index and the Engineering Compendex. Phrase frequency analysis by the technical domain experts provided the pervasive technical themes of the fullerenes database, and phrase proximity analysis provided the relationships among the pervasive technical themes. Bibliometric analysis of the fullerenes literature supplemented the DT results with author/journal/institution publication and citation data. Comparisons of fullerenes results with past analyses of similarly structured near-earth space, chemistry, hypersonic/supersonic flow, aircraft, and ship hydrodynamics databases are made. One important finding is that many of the normalized bibliometric distribution functions are extremely consistent across these diverse technical domains and could reasonably be expected to apply to broader chemical topics than fullerenes that span multiple structural classes. Finally, lessons learned about integrating the technical domain experts with the data mining tools are presented.

    In order to retrieve Chinese and foreign articles of chronotherapy, we searched Chinese databases of CBM, CMCC and foreign series databases in OVID and hence revealed and assessed the current status, research trend and level of chronotherapy in China and in foreign countries by means of scientometric and bibliometric parameters. ProCite5 software and handsearching were used to manage, check and statistically analyze the searched papers so as to find the parameters which included distributions of databases, years, authors, periodicals, subject headings, organizations and nations. 91 Chinese papers were identified which were distributed in 73 kinds of journals and in subject headings, e.g., Traditional Chinese medicine, cardiovascular diseases, neoplasms, asthma, peptic ulcer, diabetes mellitus, general review of chronotherapy, etc. 480 foreign articles were identified which mainly came from EMBASE and MEDLINE and were distributed in 285 types of journals and 35 nations and regions. There were 14 journals which recorded five or more articles. 12 researchers published more than five articles. Paul Brousse Hospital, University of Texas, University of Connecticut School of Medicine, Jichi Medical School and University of Minnesota were the core research institutes. There was no core author or core journal or core institute in China up till now. However, core authors, core journals and core research institutes had come into being in foreign countries; they were mainly from the Euro-American developed countries and had done well in chronotherapy.

    Full Text Available In this study bibliometric mapping method was employed to visualise the current research trends and the impact of the two most influential models of working memory, namely: A. D. Baddeley and G. J. Hitch’s (1974 multicomponent working memory model and N. Cowan’s (1988 embedded-processes model of working memory. Using VOSviewer software two maps were generated based on the index-term words extracted from the research papers citing Baddeley (2000 and Cowan (2001, respectively. The maps represent networks of co-occurrences of index terms and can be interpreted as an indication of the main research fields related to the examined models of WM. The results of the analysis revealed that the spheres of influence of the two main conceptualisations of WM are rather different than similar. Although the first two clusters, i.e. “brain mapping” and “higher-level cognition and development” are present in both maps, their relative importance varies. The remaining clusters are unique to each map. Baddeley’s theory seems to have a greater influence on “neuropsychology”, while Cowan’s theory - on basic research on “biological systems”, including the nervous system in humans and animals. The second difference between these theories concerns their relations to functions and dysfunctions associated with particular sensory modalities: in Baddelay’s theory with the “auditory modality” cluster, and in Cowan’s - with the “visual modality” one.

    In recent years, bibliometric science has been frequently applied in the development and evaluation of scientific research. This work presents a bibliometric analysis for the research work performed in the field of geodesy "science of the measurement and mapping of the earth surface including its external gravity field". The objective of this work is to present a complete overview of the generated research on this field to assemble and study the most important publications occurred during the past seven years. The analysis was performed including the SCOPUS and WEB OF SCIENCE databases for all the geodetic scientific articles published between 2000 and 2006. The search profile was designed considering a strategy to seek for titles and article descriptors using the terms geodesy and geodetic and some other terms associated with the topics: geodetic surfaces, vertical measurements, reference systems and frames, modern space-geodetic techniques and satellite missions. Some preliminary results had been achieved specifically Bradford law of distribution for journals and education institutes, and Lotka's law for authors that also includes the cooperation between countries in terms of writing together scientific articles. In the particular case of distributions, the model suggested by Egghe (2002) was adopted for determining the cores.

  12. 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.

    Schistosomiasis, a disease caused by a trematode, parasitic worm, is a worldwide public health problem. In spite of great progress with regard to morbidity control, even elimination of this infection in recent decades, there are still challenges to overcome in sub-Saharan Africa and endemic areas in Southeast Asia. Regarded as one of the most successful countries with respect to schistosomiasis control, The People's Republic of China has accumulated considerable experience and learnt important lessons in various local settings that could benefit schistosomiasis control in other endemic countries. Based on an analysis of conceived strengths, weaknesses, opportunities and threats (SWOT) of potential collaborative activities with regard to schistosomiasis in Africa and Asia, this article addresses the importance of collaborative efforts and explores the priorities that would be expected to facilitate the transfer of Chinese experience to low- and middle-income countries in Africa and Asia.

    2003-04-01

    We performed a bibliometric search to evaluate number and scientific "weight" of papers written by European radiologists, as compared with colleagues from other countries, to measure the contribution of European researchers to radiology journals, and to correlate bibliometric parameters with some socio-economic factors of the different European nations. We considered all peer-reviewed articles published by radiologists in biomedical journals quoted by ISI over the 1995-2000 period. To identify authors as radiologists, the string "radiol" had to appear in the address of the corresponding author, and his country was considered as the country of origin of the paper. The definition of Europe included the 15 countries of the European Union, plus Norway and Switzerland. The scientific "weight" of the paper was assumed to be the impact factor of the journal of the publication in that given year. Then, we considered the annual indexes number of papers/population and number of papers/Gross Domestic Product (GDP) in each country. Data were retrieved from the Eurostat annual statistic reviews. From these bases, we obtained a comparison of the scientific production among European radiologists, those from the U.S. and those from the rest of the world. European radiological research is responsible of almost 40% of the world scientific production in our field, and Germany, UK and France are the leading publishers in Europe. An increase of the number of papers written by European radiologists was noted in the 1995-2000 period, whereas the production from the U.S. had a slight decrease. The mean concentration indexes papers/inhabitants and papers/GDP were significantly lower in Europe than in the U.S., even if some small European countries had higher values than the U.S. As a mean, European research received a lower impact factor than that from the U.S. The assessment of research output has progressively developed as an important issue for the scientific research community

    Full Text Available Una gran parte de los estudios bibliométricos sobre colaboración científica muestra que existe un efecto de la colaboración entre investigadores en su productividad, sin embargo poco se conoce sobre la forma en que la colaboración beneficia o inhibe la productividad científica. El análisis de redes sociales provee de herramientas y métodos que permiten analizar la estructura de las redes de colaboración y también existen algunos estudios bibliométricos de redes de co-autoría en publicaciones que utilizan métodos de análisis de redes, pero aunque la mayoría de estos estudios se han realizado a nivel de disciplina científica no se ha identificado evidencia empírica que analice las redes de co-autoría y su relación con la productividad científica a nivel de grupo de investigación académico. En este artículo se analizan las redes de co-autoría de 76 grupos de investigación de la Universidad Politécnica de Valencia, y el efecto que tiene la estructura de la red de los grupos en su productividad científica. Los resultados muestran que existe una relación entre las variables de red y la productividad de los grupos. La centralidad de la red y el tamaño de la red del grupo son dos importantes variables de red para la productividad científica de los grupos. La densidad de la red y la presencia de agujeros estructurales no mostraron un efecto significativo en la productividad a nivel de grupo de investigación.Bibliometric studies of scientific collaboration show a relationship between collaboration and scientists' productivity; however, little is known about how collaboration might inhibit or enhance scientific productivity.

    material. In order to perform bibliometric and content analysis of articles written between 1994 and 2005 on inclusion in schools in two educational periodicals, 40 texts were selected and analyzed, 24 from the AMAE Educando magazine and 16 from Presença Pedagógica. The main bibliometric features of the articles on inclusion of these two magazines are: descriptive or teacher reports; personal essays; and presentation of literature and references. As to the content of these articles, the main theme is inclusion in school in general, without specification as to one or more kinds of special educational needs. They adopt an educational approach for school inclusion that does not discuss teaching levels of education services. Differences between the magazines were detected, but there were more similarities than discrepancies among them. The articles' limitations were analyzed as to theoretical and practical bases for inclusion in school.

  14. Standards for the application of bibliometrics in the evaluation of individual researchers working in the natural sciences

    2013-01-01

    Although bibliometrics has been a separate research field for many years, there is still no uniformity in the way bibliometric analyses are applied to individual researchers. Therefore, this study aims to set up standards for the use of bibliometrics in the evaluation of individual researchers working in the natural sciences. 2005 saw the introduction of the h index, which gives information about a researcher's productivity and the impact of his or her publications in a single number (h is the number of publications with at least h citations); however, it is not possible to cover the multidimensional complexity of research performance and to undertake inter-personal comparisons with this number. This study therefore includes recommendations for a set of indicators to be used for evaluating researchers. Our standards relate to the selection of data on which an evaluation is based, the analysis of the data and the presentation of the results.

  19. A complex systems approach to bibliometrics

    Science.gov (United States)

    Stringer, Michael J.

    Enabled by technological change, we are in the midst of a fundamental shift in how scientific information is produced and communicated. Electronic publishing, preprint archives, blogs, and wikis are emerging as possible viable alternatives to the current journal publishing and peer review system. However, these new technologies flood the environment with information, making it increasingly difficult to find the highest quality and most relevant papers. Additionally, accreditation and quality assessment of published material becomes nearly impossible for agencies interested in funding the research and development that is most likely to succeed. Recently, bibliometric tools have emerged as an effective means for the filtering, accreditation, and assessment of scholarly information. In this thesis, we approach bibliometrics from a complex systems perspective. A unique characteristic of the work presented in this thesis is that we perform empirical validation of bibliometric models using the most comprehensive bibliographic database available. Using these methods, we quantify the dynamics of citations to scientific journals, and investigate the relationship between social network position and research performance.

  20. First fungal genome sequence from Africa: A preliminary analysis

    2012-01-01

    Full Text Available Some of the most significant breakthroughs in the biological sciences this century will emerge from the development of next generation sequencing technologies. The ease of availability of DNA sequence made possible through these new technologies has given researchers opportunities to study organisms in a manner that was not possible with Sanger sequencing. Scientists will, therefore, need to embrace genomics, as well as develop and nurture the human capacity to sequence genomes and utilise the ’tsunami‘ of data that emerge from genome sequencing. In response to these challenges, we sequenced the genome of Fusarium circinatum, a fungal pathogen of pine that causes pitch canker, a disease of great concern to the South African forestry industry. The sequencing work was conducted in South Africa, making F. circinatum the first eukaryotic organism for which the complete genome has been sequenced locally. Here we report on the process that was followed to sequence, assemble and perform a preliminary characterisation of the genome. Furthermore, details of the computer annotation and manual curation of this genome are presented. The F. circinatum genome was found to be nearly 44 million bases in size, which is similar to that of four other Fusarium genomes that have been sequenced elsewhere. The genome contains just over 15 000 open reading frames, which is less than that of the related species, Fusarium oxysporum, but more than that for Fusarium verticillioides. Amongst the various putative gene clusters identified in F. circinatum, those encoding the secondary metabolites fumosin and fusarin appeared to harbour evidence of gene translocation. It is anticipated that similar comparisons of other loci will provide insights into the genetic basis for pathogenicity of the pitch canker pathogen. Perhaps more importantly, this project has engaged a relatively large group of scientists

    Full Text Available Glomerulonephritis (GN is a leading cause of end-stage renal disease (ESRD in Africa. Data on epidemiology and outcomes of glomerular diseases from Africa is still limited. We conducted a systematic review on the epidemiology of histologically proven glomerular diseases in Africa between 1980 and 2014.We searched literature using PubMed, AfricaWide, the Cumulative Index to Nursing and Allied Health Literature on EBSCO Host, Scopus, African Journals online databases, and the African Index Medicus, for relevant studies. The review was conducted using standard methods and frameworks using only biopsy-confirmed data.Twenty four (24 studies comprising 12,093 reported biopsies from 13 countries were included in this analysis. The median number of biopsies per study was 127.0 (50-4436, most of the studies (70.0% originated from North Africa and the number of performed kidney biopsies varied from 5.2 to 617 biopsies/year. Nephrotic syndrome was the commonest indication of renal biopsy. The frequency of reported primary pathologic patterns included, minimal change disease (MCD; 16.5% (95%CI: 11.2-22.6, focal segmental glomerulosclerosis (FSGS; 15.9% (11.3-21.1, mesangiocapillary GN (MCGN; 11.8% (9.2-14.6, crescentic GN; 2.0% (0.9-3.5 and IgA nephropathy 2.8% (1.3-4.9. Glomerular diseases related to hepatitis B and systemic lupus erythematosus had the highest prevalence among assessed secondary diseases: 8.4% (2.0-18.4 and 7.7% (4.5-11.7 respectively. There was no evidence of publication bias and regional differences were seen mostly for secondary GNs.Glomerular diseases remain poorly characterized in sub-Saharan Africa due to declining renal biopsy rates and consequent paucity of data on pathologic patterns of key renal diseases. Development of renal biopsy registries in Africa is likely to enable adequate characterization of the prevalence and patterns of glomerular diseases; this could have a positive impact on chronic kidney disease evaluation and

    2017-03-01

    Full Text Available The question of whether to carry out a quinquennial Census is faced by national statistical offices in increasingly many countries, including Canada, Nigeria, Ireland, Australia, and South Africa. We describe uses and limitations of cost-benefit analysis in this decision problem in the case of the 2016 Census of South Africa. The government of South Africa needed to decide whether to conduct a 2016 Census or to rely on increasingly inaccurate postcensal estimates accounting for births, deaths, and migration since the previous (2011 Census. The cost-benefit analysis compared predicted costs of the 2016 Census to the benefits of improved allocation of intergovernmental revenue, which was considered by the government to be a critical use of the 2016 Census, although not the only important benefit. Without the 2016 Census, allocations would be based on population estimates. Accuracy of the postcensal estimates was estimated from the performance of past estimates, and the hypothetical expected reduction in errors in allocation due to the 2016 Census was estimated. A loss function was introduced to quantify the improvement in allocation. With this evidence, the government was able to decide not to conduct the 2016 Census, but instead to improve data and capacity for producing post-censal estimates.

    Gomez, Monique

    The evaluation of the use of library collections is a fundamental tool for the development of a relevant and cost-effective collection. Bibliometrics offers several methods to measure the level of use of collections. In this paper, we present the first results of a bibliometric analysis of the references cited in the articles published by authors of the Instituto de Astrofísica de Canarias during the last decade. We have determined which kinds of publications and which journals are mainly used. We also have studied the ages of the cited journals and their cost-effectiveness. Additionally, to see if the advent of the WWW in the mid 1990s has influenced the reading or citing practices of the authors, we have compared two sets of data: articles published over the period 1991--3 that we define as the pre-WWW period and articles published over the period 1997--9 defined as the WWW period.

    Full Text Available Since 2010, the Italian Ministry of University and Research issued new evaluation protocols to select candidates for University professorships and assess the bibliometric productivity of Universities and Research Institutes based on bibliometric indicators, i.e. scientific paper and citation numbers and the h-index. Under this framework, the objective of this study was to quantify the bibliometric productivity of the Italian forest research community during the 2002-2012 period. We examined the following productivity parameters: (i the bibliometric productivity under the Forestry subject category at the global level; (ii compared the aggregated bibliometric productivity of Italian forest scientists with scientists from other countries; (iii analyzed publication and citation temporal trends of Italian forest scientists and their international collaborations; and (iv characterized productivity distribution among Italian forest scientists at different career levels. Results indicated the following: (i the UK is the most efficient country based on the ratio between Gross Domestic Spending (GDS on Research and Development (R&D and bibliometric productivity under the Forestry subject category, followed by Italy; (ii Italian forest scientist productivity exhibited a significant positive time trend, but was characterized by high inequality across authors; (iii one-half of the Italian forest scientist publications were written in collaboration with foreign scientists; (iv a strong relationship exists between bibliometric indicators calculated by WOS and SCOPUS, suggesting these two databases have the same potential to evaluate the forestry research community; and (v self-citations did not significantly affect the rank of Italian forest scientists.

  2. Exploring drought vulnerability in Africa: an indicator based analysis to be used in early warning systems

    We propose a composite drought vulnerability indicator (DVI) that reflects different aspects of drought vulnerability evaluated at Pan-African level for four components: the renewable natural capital, the economic capacity, the human and civic resources, and the infrastructure and technology. The selection of variables and weights reflects the assumption that a society with institutional capacity and coordination, as well as with mechanisms for public participation, is less vulnerable to drought; furthermore, we consider that agriculture is only one of the many sectors affected by drought. The quality and accuracy of a composite indicator depends on the theoretical framework, on the data collection and quality, and on how the different components are aggregated. This kind of approach can lead to some degree of scepticism; to overcome this problem a sensitivity analysis was done in order to measure the degree of uncertainty associated with the construction of the composite indicator. Although the proposed drought vulnerability indicator relies on a number of theoretical assumptions and some degree of subjectivity, the sensitivity analysis showed that it is a robust indicator and hence able of representing the complex processes that lead to drought vulnerability. According to the DVI computed at country level, the African countries classified with higher relative vulnerability are Somalia, Burundi, Niger, Ethiopia, Mali and Chad. The analysis of the renewable natural capital component at sub-basin level shows that the basins with high to moderate drought vulnerability can be subdivided into the following geographical regions: the Mediterranean coast of Africa; the Sahel region and the Horn of Africa; the Serengeti and the Eastern Miombo woodlands in eastern Africa; the western part of the Zambezi Basin, the southeastern border of the Congo Basin, and the belt of Fynbos in the Western Cape province of South Africa. The results of the DVI at the country level were

    The burden of hypertension in Sub-Saharan Africa has been increasing over the past few decades. However, a large proportion of the population with hypertension remains undiagnosed, untreated, or inadequately treated, contributing to the rising burden of cardiovascular disease in the region. We conducted a systematic review and meta-analysis to assess the recent burden of hypertension in Sub-Saharan Africa, based on studies published between 2000 and 2013. We pooled data from 33 surveys involving over 110 414 participants of mean age 40 years. Hypertension prevalence varied widely across the studies (range 15%-70%), partly because of differences in participant mean ages (31-76 years). The predicted prevalence of hypertension at mean participant ages of 30, 40, 50, and 60 years were 16%, 26%, 35%, and 44%, respectively, with a pooled prevalence of 30% (95% confidence interval, 27%-34%). Of those with hypertension, only between 7% and 56% (pooled prevalence: 27%; 95% confidence interval, 23%-31%) were aware of their hypertensive status before the surveys. Overall, 18% (95% confidence interval, 14%-22%) of individuals with hypertension were receiving treatment across the studies, and only 7% (95% confidence interval, 5%-8%) had controlled blood pressure. This review found a high prevalence of hypertension, as well as low percentage of hypertension awareness, treatment, and control in Sub-Saharan Africa, highlighting the need for implementation of timely and appropriate strategies for diagnosis, control, and prevention.

    Based on a content analysis using framing theory, this article examines how the microbicide trials for HIV/AIDS prevention were portrayed in local newspapers in South Africa. Twenty-nine newspaper articles on microbicide research in South Africa appeared between 2004 and 2007 in 8 major South African newspapers; 13 had extended discussions of the microbicide trials while the remainder only mentioned them in passing. Six major topics were identified in these articles: participants; consequences of microbicide use; quality of the research design; research ethics; the stopping process (i.e. the way in which the microbicide trials were halted); and "villains" and "heroes." These topics were then inductively related to three emergent categories, named by the researchers as the: malicious microbicide trial, which characterizes the trials in highly negative, and disapproving ways; the marvelous microbicide trial, which frames the trials in highly positive and approving ways; and finally the multifaceted microbicide trial, which attempts to shed light on the complexities of the issues, rather than portraying them in one-sided terms. The report concludes with a discussion of the implications of the different media portrayals for public health in South Africa.

    World-wide, the prevalence of brominated flame retardants (BFRs) is well documented for routine analysis of environmental and biological matrices. There is, however, limited information on these compounds in the African environment and insufficient information on the analytical approaches used to obtain data. This paper presents a review on BFR levels in the African environment and the various analytical methodologies specifically applied in Africa for polybrominated diphenyl ethers (PBDEs), polybrominated biphenyls and alternative-BFRs. The analyses include liquid sample preparation using liquid-liquid and solid phase extraction and solid sample preparation involving Soxhlet extraction, with ultrasound-assisted extraction increasingly being applied. Instrumental detection techniques were limited to gas chromatography coupled with electron capture detector and electron impact ionisation with single quadrupole mass spectrometers. Information on congener profile prevalence in indoor dust, soil, aquatic environment (water, sediment, and aquatic organisms), eggs, wastewater treatment plant compartments, landfills (leachate and sediment) and breast milk are presented. Although PBDEs were inconsistently detected, contamination was reported for all investigated matrices in the African environment. The manifestation in remote regions indicates the ubiquitous prevalence and long-range transport of these compounds. Levels in sediment, and breast milk from some African countries were higher than reported for Asia and Europe. Due to limited data or non-detection of alternative-BFRs, it is unclear whether banned formulations were replaced in Africa. Most of the data reported for BFR levels in Africa were obtained in non-African laboratories or in South Africa and formed the basis for our discussion of reported contamination levels and related methodologies.

    Full Text Available The presence of bovine viral diarrhoea virus in South Africa has been confirmed by several serological surveys. However, little is known about its biological properties. Twenty five isolates obtained by isolation in tissue culture and detected by means of the antigen capture ELISA from clinically sick cattle and from foetal calf serum in South Africa were characterized on the basis of analysis of the 5' non-translated (NTR region of the genome. A reverse-transcription polymerase chain reaction (RT-PCR was used to amplify specific sequences from the 5'NTR of the genome. The oligonucleotide primers corresponding to positions 105-125 and 399-378, respectively, in the sequence of BVDV strain NADL were used to generate the PCR products. Both strands were sequenced directly with these primers and fluorescence-labelled dideoxynucleotides in an automated nucleic acid sequencer. Reference strains of pestiviruses [(BVDV type I, BVDV type II, border disease virus (BDV and hog cholera virus (HCV] and isolates from a previous investigation on BVDV in southern Africa were included for comparative purposes. All the BVDV strains obtained during this study belong to subgroups of BVDV genotype I. No association could be demonstrated between the geographic origin of the isolates. A number of isolates formed another branch separate from the existing branches Ia, Ib and Ic. These findings suggest that extensive genetic diversity can be found within BVDV type I isolates from southern Africa. Isolates that group with the classical BVDV type I strains, particularly of American origin, coexist with variants that appear to represent a local genetic pool and or variants evolving from the classical strains.

    Academic nurses are increasingly turning to bibliometrics to assess the state and status of research publication in nursing in countries around the world. Early bibliometric studies were carried out by Cattell as part of a project to advance research in psychology in the early decades of the 20th century. There are some echoes in nursing's moves to increase its standing over the last 40 years. The interpretation of bibliometric studies can reveal embedded values about academic disciplinary activity and normative views of scientific work. Patterns of publishing by nurse academics appear increasingly to resemble those in biomedicine as a whole.

    The aim of this study was to characterize the scientific production of Italian Oral Surgery professionals by evaluating different bibliometric indices. The bibliometric evaluation was conducted on the Scopus Database upon all the Active Members joining three important Italian scientific societies in Oral Surgery (SIdCO, SIO, and SICOI). The scientific production was analysed by considering the number of total publications, number of total citations, h-index, and hc-index. Moreover, the overall sample was divided into two groups (Academics and Not Academics), according to the fact the professionals had or not a university position, and then into sub-groups according to the different career lengths. Statistical analyses were performed to compare the scientific productivity amongst groups. For all the considered parameters a lack of homogeneity between groups was reported, and significantly greater mean values were recorded for the Academics compared to the Not Academics Group. Moreover, the h-index values increased more regularly as the career length progressed than the hc-index values, even if the last seemed to be less variable. h- and hc-indices are both stable bibliometric parameters, but as the hc-index values are related not only to the number of citation but also to their age, it seems to be less influenced by the authors' career length. Bibliometric analysis of the scientific production in dentistry may facilitate the recognition of factors that may further enhance research activity and clinical performance and be useful for a comparative assessment of authors or research groups in terms of quality and quantity of the scientific production.

    journals, thus provide reference for the researchers, research management department and journal editors. We collected bibliometric data of abroad papers published from 2002 to 2011 by authors from China in fishery research field. By using bibliometric, classified statistics and social network analysis methods, we analyzed the distribution of core authors and institutions, journal and subject distribution of the papers, interna-tional cooperation, cooperative network of authors and organizations, and research hotsports. The results showed that the overall amount of the published articles and times cited of Chinese authors in 2002−2011 experienced great growth. We got 70 core authors by ranking with core indexes and analyzed their characteristics of publishing paper and citation. Chinese authors in fishery field are mainly involved in the subjects of Marine and Freshwater Biology and Fisheries, which cross frequently with other subjects such as environmental sciences ecology, ocean-ography, and biotechnology & applied microbiology.

    2013-01-01

    Full Text Available Background: This article provided an analysis of gender inequality, health expenditure and its relationship to maternal mortality.Objective: The objective of this article was to explore gender inequality and its relationship with health expenditure and maternal mortality in sub-Saharan Africa (SSA. A unique analysis was used to correlate the Gender Inequality Index (GII, Health Expenditure and Maternal Mortality Ratio (MMR. The GII captured inequalities across three dimensions – Reproductive health, Women empowerment and Labour force participation between men and women. The GII is a composite index introduced by the UNDP in 2010 and corrects for the disadavanatges of the other gender indices. Although the GII incorporates MMR in its calculation, it should not be taken as a substitute for, but rather as complementary to, the MMR.Method: An exploratory and descriptive design to a secondary documentary review using quantitative data and qualitative information was used. The article referred to sub-Saharan Africa, but seven countries were purposively selected for an in-depth analysis based on the availability of data. The countries selected were Angola, Botswana, Malawi, Mozambique,South Africa, Zambia and Zimbabwe.Results: Countries with high gender inequality captured by the gender inequality index were associated with high maternal mortality ratios as compared with countries with lower gender inequality, whilst countries that spend less on health were associated with higher maternal deaths than countries that spend more.Conclusion: A potential relationship exists between gender inequality, health expenditure, and maternal mortality. Gender inequalities are systematic and occur at the macro, societal and household levels.

    Full Text Available Aims: To track citation patterns in ophthalmic journals and contrast them with major medical and surgical journals from 1997 to 2009. In addition, we want to familiarize the ophthalmic community with bibliometrics indices. Materials and Methods: Data retrieved from Institute for Scientific Information and related websites include 2-year journal impact factor JIF, 5-year impact, Eigenfactor score, H-factor, Article Influence score, and SCImago factor. Results: JIF rose steadily around 10% annually in ophthalmic journals, and likewise for major medical and surgical journals. JIF correlated with recent bibliometric indicators like 5-year impact, H index, and SCImago factor but not with Eigenfactor. Ophthalmic journals publishing reviews, basic science, or large volume on broad range of topics ranked at the top for JIF, while subspecialty journals tended to have low JIF. JIF of subspecialty journal Retina rose from 0.740 (rank 23 in 2000 to 3.088 in 2007 (rank 6. Conclusions: JIF tends to rise annually by 10% in medical, surgical, and ophthalmic fields. Journals publishing reviews, basic science, or large volume on broad range of topics rank at the top for JIF. The rapid rise of JIF for Retina unlike other subspecialties that stayed status quo is multifactorial: Change in editorial policies (introduction of review articles and omission of case reports and technological advances in the retinal field.

  2. Exploring drought vulnerability in Africa: an indicator based analysis to inform early warning systems

    Drought vulnerability is a complex concept that includes both biophysical and socio-economic drivers of drought impact that determine capacity to cope with drought. In order to develop an efficient drought early warning system and to be prepared to mitigate upcoming drought events it is important to understand the drought vulnerability of the affected regions. We propose a composite Drought Vulnerability Indicator (DVI) that reflects different aspects of drought vulnerability evaluated at Pan-African level in four components: the renewable natural capital, the economic capacity, the human and civic resources, and the infrastructure and technology. The selection of variables and weights reflects the assumption that a society with institutional capacity and coordination, as well as with mechanisms for public participation is less vulnerable to drought; furthermore we consider that agriculture is only one of the many sectors affected by drought. The quality and accuracy of a composite indicator depends on the theoretical framework, on the data collection and quality, and on how the different components are aggregated. This kind of approach can lead to some degree of scepticism; to overcome this problem a sensitivity analysis was done in order to measure the degree of uncertainty associated with the construction of the composite indicator. Although the proposed drought vulnerability indicator relies on a number of theoretical assumptions and some degree of subjectivity, the sensitivity analysis showed that it is a robust indicator and hence able of representing the complex processes that lead to drought vulnerability. According to the DVI computed at country level, the African countries classified with higher relative vulnerability are Somalia, Burundi, Niger, Ethiopia, Mali and Chad. The analysis of the renewable natural capital component at sub-basin level shows that the basins with high to moderate drought vulnerability can be subdivided in three main different

    2013-08-15

    This paper presents a SWOT analysis of SEA systems in the Middle East North Africa region through a comparative examination of the status, application and structure of existing systems based on country-specific legal, institutional and procedural frameworks. The analysis is coupled with the multi-attribute decision making method (MADM) within an analytical framework that involves both performance analysis based on predefined evaluation criteria and countries' self-assessment of their SEA system through open-ended surveys. The results show heterogenous status with a general delayed progress characterized by varied levels of weaknesses embedded in the legal and administrative frameworks and poor integration with the decision making process. Capitalizing on available opportunities, the paper highlights measures to enhance the development and enactment of SEA in the region.

METHODS: Articles related to TTC published in the PubMed database during the years 2009 to 2011 were selected. Subject heading (MeSH) terms of the articles were downloaded and the frequency of the major MeSH terms was statistically calculated. High-frequency MeSH terms in the literature formed the co-word matrix by the appearance frequency of a pair of MeSH terms in the same literature. The co-word analysis was used to cluster these medical MeSHs. The research focus was obtained after statistically analyzing the contents of each cluster. RESULTS: A total of 646 articles associated with TTC were found in the PubMed database and 34 MeSH terms appeared more than six times. The MeSH term " Takotsubo cardiomyopathy/diagnosis" was found with the highest

    The NASA Astrophysics Data System (ADS), along with astronomy's journals and data centers (a collaboration dubbed URANIA), has developed a distributed on-line digital library which has become the dominant means by which astronomers search, access and read their technical literature. Digital libraries such as the NASA Astrophysics Data System \\citep{2005JASIS.tmp....2K} permit the easy accumulation of a new type of bibliometric measure, the number of electronic accesses (``reads'') of individual articles. We explore various aspects of this new measure. We examine the obsolescence function as measured by actual reads, and show that it can be well fit by the sum of four exponentials with very different time constants. We compare the obsolescence function as measured by readership with the obsolescence function as measured by citations. We find that the citation function is proportional to the sum of two of the components of the readership function. This proves that the normative theory of citation is true in the mean. We further examine in detail the similarities and differences between the citation rate, the readership rate and the total citations for individual articles, and discuss some of the causes. Using the number of reads as a bibliometric measure for individuals, we introduce the read-cite diagram to provide a two-dimensional view of an individual's scientific productivity. We develop a simple model to account for an individual's reads and cites and use it to show that the position of a person in the read-cite diagram is a function of age, innate productivity, and work history. We show the age biases of both reads and cites, and develop two new bibliometric measures which have substantially less age bias than citations: SumProd, a weighted sum of total citations and the readership rate, intended to show the total productivity of an individual; and Read10, the readership rate for papers published in the last ten years, intended to show an individual's current

    Full Text Available In January 2007, the Chilean Journal of Agricultural Research was indexed by the Institute of Scientific Information (ISI. This paper reviews the research that has been published since 2007 by using records extracted from the Web of Science database. The papers published were mostly affiliated to researchers from Chile, and six out of the ten most-contributing countries were from Latin America. The analysis by institutions showed Universidad de Concepcion as the most prolific, although this result is not valid. A lack of standardization in the manner the Instituto de Investigaciones Agropecuarias (INIA subscribed its address on each paper caused a disaggregation of the information. This was proven by the manual curation of each record that was affiliated to any of the centers belonging to INIA. The journal has a self-citation rate of 19.3%, value that is relatively high if compared to other journals from the same subject category listed on The Journal Citation Reports 2010. Finally, this work should be considered a bibliometric snapshot of the current situation of the journal that will serve as a benchmark when new evaluations are made in a few-years time.En enero 2007, la revista Chilean Journal of Agricultural Research fue indexada por el Institute of Scientific Information (ISI, por lo que este artículo analiza la investigación que ha sido publicada desde el año 2007 utilizando los registros extraídos de la base de datos Web of Science.

Un análisis por institución mostró a la Universidad de Concepción como la más prolífica, aunque este resultado no es válido por una ausencia de estandarización en la manera que el Instituto de Investigaciones Agropecuarias (INIA suscribe su dirección en cada artículo, lo que provoca disgregación de la información.

    Human health impairment induced by pesticide exposure has become a hot research topic. In this study, a bibliometric analysis on 481 English articles indexed by Science Citation Index Expanded (SCI-E) and Social Sciences Citation Index (SSCI) in Web of Science, and 46 Chinese articles indexed by China National Knowledge Infrastructure (CNKI) has been conducted. Generally, the number of articles about the health impairment induced by pesticide exposure is increasing, and the developed countries represented by the United States of America play a dominant role in this research field. The case-control study, the cohort study and the cross-sectional study are the three major research types, and Logistic regression and linear regression are the two most commonly adopted quantitative research methods. The impairment effect induced by pesticide exposure on all the human body systems, especially the nerve system, the reproductive system, and the circulatory system are the major research areas, which have also become the hot research issues during the period of 2011 to 2015. Substantial articles have also analyzed the correlations between pesticide exposure and the human cancer as well as death. It is noteworthy that there is a large gap between China and the developed countries in terms of the research performance in the field of the health impairment induced by pesticide exposure.%农药暴露对人体的健康损害已成为热点研究课题。对 Web of Science平台中 Science Citation Index Expanded (SCI-E)和 Social Sciences Citation Index (SSCI)检索的481篇英文论文和中国知网(CNKI)收录的46篇中文论文进行了文献计量分析。农药暴露对健康损害的论文数量总体呈现上升趋势,而以美国为代表的发达国家在该方面研究中占据主导地位。病例对照研究、队列研究和横截面研究是该方面最主要研究类型,而 Logistic回归和线性回归是被采用最多的定量研究方法。农药暴露

    Full Text Available Abstract Background Given the size of the HIV epidemic in South Africa and other developing countries, scaling up antiretroviral treatment (ART represents one of the key public health challenges of the next decade. Appropriate priority setting and budgeting can be assisted by economic data on the costs and cost-effectiveness of ART. The objectives of this research were therefore to estimate HIV healthcare utilisation, the unit costs of HIV services and the cost per life year (LY and quality adjusted life year (QALY gained of HIV treatment interventions from a provider's perspective. Methods Data on service utilisation, outcomes and costs were collected in the Western Cape Province of South Africa. Utilisation of a full range of HIV healthcare services was estimated from 1,729 patients in the Khayelitsha cohort (1,146 No-ART patient-years, 2,229 ART patient-years using a before and after study design. Full economic costs of HIV-related services were calculated and were complemented by appropriate secondary data. ART effects (deaths, therapy discontinuation and switching to second-line were from the same 1,729 patients followed for a maximum of 4 years on ART. No-ART outcomes were estimated from a local natural history cohort. Health-related quality of life was assessed on a sub-sample of 95 patients. Markov modelling was used to calculate lifetime costs, LYs and QALYs and uncertainty was assessed through probabilistic sensitivity analysis on all utilisation and outcome variables. An alternative scenario was constructed to enhance generalizability. Results Discounted lifetime costs for No-ART and ART were US$2,743 and US$9,435 over 2 and 8 QALYs respectively. The incremental cost-effectiveness ratio through the use of ART versus No-ART was US$1,102 (95% CI 1,043-1,210 per QALY and US$984 (95% CI 913-1,078 per life year gained. In an alternative scenario where adjustments were made across cost, outcome and utilisation parameters, costs and outcomes

    Full Text Available Objective: To explore and analyze the indications and causes of cesarean section on Pemba island of Zanzibar in Africa to improve the quality of obstetrics. Methods: 564 patients performed cesarean section in Abdulla Mzee Hospital of Pemba from January, 2008 to December, 2011 were selected, and statistics was conducted by the method of retrospective analysis. Results: The rate of cesarean section in Abdulla Mzee Hospital of Pemba was 10.01%. The primary causes of cesarean section included cephalopelvic disproportion (27.13%, scar uterus (23.40%, preeclampsia and eclampsia (13.30%, fetal distress in uterus (9.40%, fetal factors (9.75% and complication of pregnancy (6.91%. Conclusion: Cesarean section plays a great role in the treatment of dystocia, some complications of pregnancy and reducing the mortality of pregnant women and perinatal infants, but in the area with relatively undeveloped medical conditions in Africa, cesarean section still takes great risks. Unnecessary cesarean section cannot reduce the incidence of postpartum hemorrhage and neonatal morbidity. The local medical staff should improve the midwifery technique, establish and perfect the formal antenatal examination system to improve the quality of maternity.

    Phillips, James F; Sheff, Mallory; Boyer, Christopher B

    2015-09-01

    Growing international concern about the need for improved health systems in Africa has catalyzed an expansion of the health systems literature. This review applies a bibliometric procedure to analyze the acceleration of scientific writing on this theme. We focus on research published during the Millennium Development Goal (MDG) era between 1990 and 2014, reporting findings from a systematic review of a database comprised of 17,655 articles about health systems themes from sub-Saharan African countries or subregions. Using bibliometric tools for co-word textual analysis, we analyzed the incidence and associations of keywords and phrases to generate and visualize topical foci on health systems as clusters of themes, much in the manner that astronomers represent groupings of stars as galaxies of celestial entities. The association of keywords defines their relative position, with the size of images weighted by the relative frequency of terms. Sets of associated keywords are arrayed as stars that cluster as "galaxies" of concepts in the knowledge universe represented by health systems research from sub-Saharan Africa. Results show that health systems research is dominated by literature on diseases and categorical systems research topics, rather than on systems science that cuts across diseases or specific systemic themes. Systems research is highly developed in South Africa but relatively uncommon elsewhere in the region. "Black holes" are identified by searching for terms in our keyword library related to terms in widely cited reviews of health systems. Results identify several themes that are unexpectedly uncommon in the country-specific health systems literature. This includes research on the processes of achieving systems change, the health impact of systems strengthening, processes that explain the systems determinants of health outcomes, or systematic study of organizational dysfunction and ways to improve system performance.

    2012-04-01

    Ellison (1944) developed the splash board as a system for measuring splash erosion that was both cheap and reliable. Bollinne (1975), Morgan (1978, 1981). Mutchler (1967) described another different type of splash detectors according to whether they were passive or could register data. In the study mentioned above these authors included bottles, funnels, glasses, photography, markers. After that several devices has been made up like the splash sampler (Leguedois et al., 2005), soil tray (Van Dijk et al., 2002), splash funnel (Terry, 1989) and several rain cups (Fernandez-Raga et al., 2010; Molina and Llinares, 1996; Torri et al., 1987). Splash erosion research has materialized in the form of a number of papers published in international journals. The database of bibliographic references employed has been one of the most prestigious ones: theWeb of Science (ISI). The search was carried out on January 27th 2012. Among the 3x10^8 scholarly documents included in the Science Citation Index Expanded (SCI-EXPANDED) 1899 to present , the searching engine located 439 containing the word "splash erosion*", where the asterisk acts as a wildcard for any letter or group of letters. Of these, 383 were classified as articles, 87 as proceeding papers, 5 as editorial material, 2 as notes and 1 as correction. These documents have been published in 163 different journals, although four are particularly recurrent: Earth surface processes and Landforms, Catena, Soil Science Society of America Journal and Hydrological processes, with 41, 35, 35 and 26 published documents respectively. A geographic analysis of these articles has been carried out in an attempt to determine in what parts of the world research projects were making use of splash erosion. The results are that anglo-saxon countries, as USA, England and Australia dominate, particularly USA, with 130 articles. China and Japan are large communities of researches too, and some Central European countries as Belgium, France Germany

Within the domain analysis, a most suitable bibliometric method of revealing the structure of the discipline has been selected, which is an empirical view of the underlying structure in psychological studies and is interesting since the majority of scientists have an intuitive idea that it may or may not correspond to reality. In this case, this paper analyzes core journal papers collected by CNKI and maps their dynamics of psychology in 2000-2004 and 2005-2009 respectively. A group of six journals were selected from the most prestigious psychological journals judged to be the main contributors to the field. All of their cocitations identified were downloaded to be analyzed by factor or cluster analysis. There are 19,107 key words in 2000-2004 and 28,123 in 2005-2009. Therefore the resulting representation permits us to group the high-frequency words according to the similarity of subject matter marked by the researcher. The cluster analysis resulted in 10 clusters in 2000-2004 and 12 in 2005-2009, which can explain 83 % of the total information. Compared with 2000- 2004, in the phase of 2005-2009, the fifteen words which emerged as the most frequent words appearing more than 150 times were those related to "emotion (affection)", "self-efficacy(self-esteem) ", "study(learn)", "personality", "job(work)", "cognitive", "memory",

    Full Text Available We made use of groundwater flow and mass transport equations to investigate the crucial potential risk of water pollution from hydraulic fracturing especially in the case of the Karoo system in South Africa. This paper shows that the upward migration of fluids will depend on the apertures of the cement cracks and fractures in the rock formation. The greater the apertures, the quicker the movement of the fluid. We presented a novel sampling method, which is the combination of the Monte Carlo and the Latin hypercube sampling. The method was used for uncertainties analysis of the apertures in the groundwater and mass transport equations. The study reveals that, in the case of the Karoo, fracking will only be successful if and only if the upward methane and fracking fluid migration can be controlled, for example, by plugging the entire fracked reservoir with cement.

    Six permanent GPS stations have been deployed in West Africa within the framework of the African Monsoon Multidisciplinary Analysis (AMMA) project in order to monitor precipitable water vapor (PWV) estimates. This quantity turns out to be relevant for computing water budgets to study atmospheric processes associated with the monsoon precipitations. 90% of annual rainfalls in Sahel are produced by Mesoscale Convective Systems (MCSs). During these extreme meteorological conditions, the residuals of GPS phase measurements show strong variations that are spatially and temporally correlated with the passages of the MCSs. Using in-situ observations of pressure, temperature and humidity, brightness temperatures from Meteosat and measurements of reflectivity from MIT C-band Doppler radar, we analysed the cases of MCS over Niamey (Niger) during the whole rainy season of 2006. We found some signals in GPS phase residuals in connection with the structure of MCS. These signals could be used to better understand and classify these extreme meteorological events.

    Full Text Available The objective of this study was to characterise meteorological droughts in the Central Region of South Africa using Standardised Precipitation Evapotranspiration Index (SPEI and to examine if there is a relationship between drought and El Niño events. The SPEI was used to quantify the precipitation deficit over time and space across the catchment for the time-scales that are important for planning and management of water resources. Based on 12-month time-scale, the total number of drought events identified in the area using SPEI ranged between 13 and 20 during the period of analysis (1952–1999. Considering the effects of event magnitude and duration as severity parameters, the most severe drought event was identified during 1973 followed by 1995 based on 12-month time-scale. Moreover, it was also found that the number of moderate, severe, and extreme drought events identified by SPEI follows increasing trend with decade during the period of analysis. Results of Spearman’s rank correlation test revealed that the trends exhibited by mild (SPEI-3 and SPEI-6, moderate (SPEI-12, severe (SPEI-12, and extreme (SPEI-3 drought categories are statistically significant at 5% significance level. The study also revealed that drought events in the central region of South Africa are preceded by El Niño events in the tropical Pacific (Nino 3.4 with an average lag time of 8 months between the onsets of the two events. It was found that hydrological drought events in the study area lag behind meteorological drought events with an average lag time of 7.4 months. Findings of this study can be used to forecast drought events in the area for the proper planning and management of water resources.

    Full Text Available Land cover change analysis was performed for three catchments in the rural Eastern Cape, South Africa, for two time steps (2000 and 2014, to characterize landscape conversion trajectories for sustained landscape health. Land cover maps were derived: (1 from existing data (2000; and (2 through object-based image analysis (2014 of Landsat 8 imagery. Land cover change analysis was facilitated using land cover labels developed to identify landscape change trajectories. Land cover labels assigned to each intersection of the land cover maps at the two time steps provide a thematic representation of the spatial distribution of change. While land use patterns are characterized by high persistence (77%, the expansion of urban areas and agriculture has occurred predominantly at the expense of grassland. The persistence and intensification of natural or invaded wooded areas were identified as a degradation gradient within the landscape, which amounted to almost 10% of the study area. The challenge remains to determine significant signals in the landscape that are not artefacts of error in the underlying input data or scale of analysis. Systematic change analysis and accurate uncertainty reporting can potentially address these issues to produce authentic output for further modelling.

    2015-04-03

    This study draws on publication and citation data related to plant biotechnology from a 10-year (2004–2013) period to assess the research performance, impact, and collaboration of member states of the Association of Southeast Asian Nations (ASEAN). Plant biotechnology is one of the main areas of cooperation between ASEAN member states and among the research areas promoted to achieve regional food security and sustainable development. In general, findings indicate increased scientific output, influence, and overall collaboration of ASEAN countries in plant biotechnology over time. Research performance and collaboration (domestic, regional, and international) of the region in plant biotechnology are linked to the status of the economic development of each member country. Thailand produced the most publications of the ASEAN member states while Singapore had the highest influence as indicated by its citation activity in plant biotechnology among the ASEAN countries. Domestic and international collaborations on plant biotechnology are numerous. Regional collaboration or partnership among ASEAN countries was, however, was found to be very limited, which is a concern for the region’s goal of economic integration and science and technology cooperation. More studies using bibliometric data analysis need to be conducted to understand plant biotechnology cooperation and knowledge flows between ASEAN countries. © 2015 Akadémiai Kiadó, Budapest, Hungary

  8. Examining semantics in interprofessional research: A bibliometric study.

    Perrier, Laure; Adhihetty, Chamila; Soobiah, Charlene

    2016-05-01

    While experts in the field provide clarity between terms such as interprofessional and multidisciplinary, the published literature may not be offering this preciseness. A bibliometric analysis was conducted on 1,148 studies that examined terms such as interprofessional, multidisciplinary, and teamwork in order to examine patterns of indexing, overlap in how terms and phrases are used by authors, and consistencies in the definitions of terminology. A small number of relevant indexing terms are available in PubMed but were not regularly applied to the studies in this subject area. Our findings indicate that relying on indexing terms to locate this body of literature will not reliably identify all relevant studies when searching the literature. Definitions for these terms were typically not offered by authors, references were not regularly provided when definitions were included, and clear distinctions between the different terms were not reliably provided, thus creating further difficulties. Poor indexing, lack of consistent definitions being used in the research literature, and some authors using phrases and terms as synonyms make it challenging for educators, scholars, and researchers to search, find, and use this body of literature.

    This investigation was made to reveal the current status, research trend and research level of biomedical engineering in Chinese mainland by means of scientometrics and to assess the quality of the four domestic publications by bibliometrics. We identified all articles of four related publications by searching Chinese and foreign databases from 1997 to 2001. All articles collected or cited by these databases were searched and statistically analyzed for finding out the relevant distributions, including databases, years, authors, institutions, subject headings and subheadings. The source of sustentation funds and the related articles were analyzed too. The results showed that two journals were cited by two foreign databases and five Chinese databases simultaneously. The output of Journal of Biomedical Engineering was the highest. Its quantity of original papers cited by EI, CA and the totality of papers sponsored by funds were higher than those of the others, but the quantity and percentage per year of biomedical articles cited by EI were decreased in all. Inland core authors and institutions had come into being in the field of biomedical engineering. Their research topics were mainly concentrated on ten subject headings which included biocompatible materials, computer-assisted signal processing, electrocardiography, computer-assisted image processing, biomechanics, algorithms, electroencephalography, automatic data processing, mechanical stress, hemodynamics, mathematical computing, microcomputers, theoretical models, etc. The main subheadings were concentrated on instrumentation, physiopathology, diagnosis, therapy, ultrasonography, physiology, analysis, surgery, pathology, method, etc.

    2014-06-01

    The subject of our present paper is the analysis of the origins or historical roots of the Higgs boson research from a bibliometric perspective, using a segmented regression analysis in combination with a method named reference publication year spectroscopy (RPYS). Our analysis is based on the references cited in the Higgs boson publications published since 1974. The objective of our analysis consists of identifying specific individual publications in the Higgs boson research context to which the scientific community frequently had referred to. We are interested in seminal works which contributed to a high extent to the discovery of the Higgs boson. Our results show that researchers in the Higgs boson field preferably refer to more recently published papers —particularly papers published since the beginning of the sixties. For example, our analysis reveals seven major contributions which appeared within the sixties: Englert and Brout (1964), Higgs (1964, 2 papers), and Guralnik et al. (1964) on the Higgs mechanism as well as Glashow (1961), Weinberg (1967), and Salam (1968) on the unification of weak and electromagnetic interaction. Even if the Nobel Prize award highlights the outstanding importance of the work of Peter Higgs and Francois Englert, bibliometrics offer the additional possibility of getting hints to other publications in this research field (especially to historical publications), which are of vital importance from the expert point of view.

  12. Beyond bibliometrics harnessing multidimensional indicators of scholarly impact

    CERN Document Server

    Sugimoto, Cassidy R

    2014-01-01

    Bibliometrics has moved well beyond the mere tracking of bibliographic citations. The web enables new ways to measure scholarly productivity and impact, making available tools and data that can reveal patterns of intellectual activity and impact that were previously invisible: mentions, acknowledgments, endorsements, downloads, recommendations, blog posts, tweets. This book describes recent theoretical and practical advances in metrics-based research, examining a variety of alternative metrics -- or "altmetrics" -- while also considering the ethical and cultural consequences of relying on metrics to assess the quality of scholarship. Once the domain of information scientists and mathematicians, bibliometrics is now a fast-growing, multidisciplinary field that ranges from webometrics to scientometrics to influmetrics. The contributors to Beyond Bibliometrics discuss the changing environment of scholarly publishing, the effects of open access and Web 2.0 on genres of discourse, novel analytic methods, and the e...

  13. Bibliometric indicators for evaluating the quality of scientifc publications.

    Science.gov (United States)

    Joshi, Medha A

    2014-03-01

    Evaluation of quality and quantity of publications can be done using a set of statistical and mathematical indices called bibliometric indicators. Two major categories of indicators are (1) quantitative indicators that measure the research productivity of a researcher and (2) performance indicators that evaluate the quality of publications. Bibliometric indicators are important for both the individual researcher and organizations. They are widely used to compare the performance of the individual researchers, journals and universities. Many of the appointments, promotions and allocation of research funds are based on these indicators. This review article describes some of the currently used bibliometric indicators such as journal impact factor, crown indicator, h-index and it's variants. It is suggested that for comparison of scientific impact and scientific output of researchers due consideration should be given to various factors affecting theses indicators.

    ObjectiveTo analyze the status quo of and review the research of fungal bioiflm worldwide by an overview of related literatures from PubMed, so as to provide ideas and basis for further research.MethodsMedical literatures on the research of fungal bioiflm in PubMed database were analyzed by using bibliometric tools such as Thomson data analyzer. The distributions of years, nations, journals, and currently hot topics on fungal bioiflm, and top-20 cited papers were analyzed.ResultsThe number of the papers published every year on fungal bioiflm was stable from 1981 to now. United States and Europe had leading advantages in this ifeld. The journal published the most papers of fungal bioiflm was American and European journals. Three of the top-10 authors of the most publications came from center for medical mycology, department of dermatology, university hospitals of cleveland, case western reserve university, which illustrates these research institutes in a leadership position in this ifeld. Researches focused on formation of medical fungal bioiflm, as well as its interaction with antifungal medicine and basis of this virulence related genes and proteins. The trend of citation analysis and qualifying contributions to the literature has some consistency. Researches in China are mainly from Hong Kong and Beijing, but there is an obvious gap between China and Europe or America.ConclusionUnited States and Europe are the leaders in this ifeld. The numbers and citation rates of the papers from China in this ifeld have been increasing in recent 5 years. The hot topics in this ifeld were the formation of fungal bioiflm, susceptibilities and mechanism of this virulence.%目的:分析全球医学真菌生物膜文献概貌,了解医学真菌生物膜研究现状,为进一步研究提供思路和依据。方法利用汤森路透的TDA软件分析PubMed数据库收录的医学真菌生物膜相关文献的时间、国家、期刊、作者和高频主

    Full Text Available Externalities are an integral part of South Africa’s electricity power generation sector as the country is highly dependent on coal as the primary fuel source. While there have been significant efforts to account for the constantly increasing externalities in developed countries, it has not been the case in the developing world. This paper attempts to observe the trend of externalities research in South Africa’s power generation sector and to analyse the gaps by placing externality research in context with other studies performed internationally. A statistical analysis adjusted for currency conversions puts into perspective the range of externalities. It also provides an overview of South Africa’s energy supply and demand scene, with emphasis on the role of coal in the electricity sector. The paper provides motivation to perform a revised externality analysis along international lines. The aim is to add to the body of literature on externality studies in South Africa by providing an updated comparative analysis. This will enable future research to contextualise studies that were performed during different time periods.

    Full Text Available The bibliometric characteristics of electronic journals (e-journals covering the field of information science have been studied. Twenty-eight e-journals were identified and ranked by number of articles on the subject they published. A Bradford plot revealed that the core is not well developed yet, but it will likely contain six journals. The publication of information science articles in e-journals began modestly in 1995 with 26 articles, but it has risen to approximately 250 articles per year. The most prolific authors are identified. The vast majority of them are located in the United States or United Kingdom. Only 26 articles have authors from more than one country, showing that electronic technology has not yet strongly influenced international collaboration. About 2/3 of the articles originate in academic institutions. Common topics of e-journal articles in information science include electronic information, electronic publishing, virtual (digital libraries, information search and retrieval, and use of the Internet. Seven online databases cover these e-journals; Information Science Abstracts is the only one to cover all 28 journals, and it has the highest number of abstracts from them - over 1,100.

    Fructans isolated from Agave americana grown in South Africa are currently used for spirit production. Structural studies on water-soluble fructans were performed to facilitate the development of other applications including its use as a prebiotic. Acid hydrolysis followed by HPAEC-PAD analysis confirmed that the fructan was composed of glucose and fructose, and size analysis by HPAEC-PAD and size exclusion chromatography indicated that the saccharides have a DP range from 6 to 50. An average DP of 14 was estimated by (1)H NMR analysis. Linkage analysis and ESI-MS studies suggest that A. americana has a neofructan structure consisting of a central sucrose to which (2 → 1)- and (2 → 6)-linked β-D-Fruf chains are attached. The (2 → 1)-linked units extend from C-1 of Fru and C-6 of glucose, whereas the (2 → 6)-linked β-D-Fruf units are attached to C-6 of the central Fru. This structure accounts for the presence of equimolar amounts of 1,6-linked Glu and 1,2,6-linked Fru found in linkage analysis and the multiplicity of the NMR signals observed. Detailed ESI-MS studies were performed on fructan fractions: native, periodate oxidized/reduced, and permethylated oligomers. These derivatizations introduced mass differences between Glc and Fru following oxidation and between 1,2-, 1,6-, 2,6-, and 1,2,6-linked units after methylation. Thus, ESI-MS showed the presence of a single Glc per fructan chain and that it is predominantly internal, rather than terminal as found in inulin. These structural features were confirmed by the use of 1D and 2D NMR experiments.

    Full Text Available A checklist of vascular plants of Platberg was compiled to determine species richness, rarity and endemism. The floristic analysis is part of the Department of Economic, Tourism and Environmental Affairs Free State biodiversity assessment programme and conservation management plan for Platberg. The analysis identified a total of 669 species belonging to 304 genera and 95 families, with 214 species belonging to the Monocotyledoneae and 438 species to the Dicotyledoneae. The largest family is Asteraceae with 126 species, followed by Poaceae with 73 species, Cyperaceae with 39 species, Fabaceae with 33 species, and Scrophulariaceae with 27 species. Various fynbos species were found, as well as 26 endemic/near-endemic species belonging to the Drakensberg Alpine Centre or Eastern Mountain Region. The results of this study revealed that Platberg shares inselberg floral richness and endemism that can be tracked via the Afromontane archipelago-like string of inselbergs and mountains, which stretch north through the Chimanimani Mountains, into Malawi, the Eastern Arc Mountains via Tanzania and north through Ethiopia, into Eurasia.Conservation implications: Platberg, as an inselberg, is a site of significant biological diversity, with high species richness, vegetation selection and ecosystem complexity. It shares floral richness and endemism via inselbergs and mountains throughout Africa. The high species richness, Red Data species and ecosystems make this area an important conservation site that should be legislated and protected.

    Full Text Available Abstract Background Scientific publications play an important role in scientific process providing a key linkage between knowledge production and use. Scientific publishing activity worldwide over the past decades shows that most countries in Africa have low levels of publication. We sought to examine trends and contribution of different Africa subregions and individual countries as represented by the articles indexed by PubMed between 1996 and 2005. Results Research production in Africa is highly skewed; South Africa, Egypt, and Nigeria make up a striking 60% of the total number of articles indexed by PubMed between 1996 and 2005. When adjusted for population size smaller countries, such as The Gambia, Gabon and Botswana, were more productive than Nigeria and Kenya. The Gambia and Eritrea had better records when total production was adjusted for gross domestic product. The contribution of Africa to global research production was persistently low through the period studied. Conclusion In this study, we found that most populous and rich countries (such as South Africa, Egypt, and Nigeria have correspondingly higher research production; but smaller countries can be productive. We noted continuous increases and reassuring trends in the production of research articles from all African subregions during the period 1996 – 2005. However, contribution of Africa to global research production was limited.

    The shift in emphasis to universal primary health care in post-apartheid South Africa has been accompanied by a process of decentralization of mental health services to district level, as set out in the new Mental Health Care Act, no. 17, of 2002 and the 1997 White Paper on the Transformation of the Health System. This study sought to assess progress in South Africa with respect to deinstitutionalization and the integration of mental health into primary health care, with a view to understanding the resource implications of these processes at district level. A situational analysis in one district site, typical of rural areas in South Africa, was conducted, based on qualitative interviews with key stakeholders and the World Health Organization's Assessment Instrument for Mental Health Systems (WHO-AIMS). The findings suggest that the decentralization process remains largely limited to emergency management of psychiatric patients and ongoing psychopharmacological care of patients with stabilized chronic conditions. We suggest that, in a similar vein to other low- to middle-income countries, deinstitutionalization and comprehensive integrated mental health care in South Africa is hampered by a lack of resources for mental health care within the primary health care resource package, as well as the inefficient use of existing mental health resources.

    Introduction Congenital heart diseases (CHD) are common causes of cardiovascular morbidity and mortality among young children and adolescents living in Africa. Accurate epidemiological data are needed in order to evaluate and improve preventive strategies. This review aims to determine the prevalence of CHD and their main patterns in Africa. Methods and analysis This systematic review and meta-analysis will include cross-sectional, case–control and cohort studies of populations residing inside African countries, which have reported the prevalence of CHD, confirmed by an echocardiographic examination and/or describing different patterns of these abnormalities in Africa. Relevant abstracts published without language restriction from 1 January 1986 to 31 December 2016 will be searched in PubMed, Exerpta Medica Database and online African journals as well as references of included articles and relevant reviews. Two review authors will independently screen, select studies, extract data and assess the risk of bias in each study. The study-specific estimates will be pooled through a random-effects meta-analysis model to obtain an overall summary estimate of the prevalence of CHD across studies. Clinical and statistical heterogeneity will be assessed, and we will pool studies judged to be clinically homogeneous. On the other hand, statistical heterogeneity will be evaluated by the χ2 test on Cochrane's Q statistic. Funnel-plots analysis and Egger's test will be used to detect publication bias. Results will be presented by geographic region (central, eastern, northern, southern and western Africa). Ethics and dissemination The current study will be based on published data, and thus ethical approval is not required. This systematic review and meta-analysis is expected to serve as a base which could help in estimating and evaluating the burden of these abnormalities on the African continent. The final report of this study will be published in a peer-reviewed journal. Trial

    2016-01-01

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

    Objective The hypertension epidemic in Africa collectively with very low rates of blood pressure control may predict an incremented prevalence of resistant hypertension (RH) across the continent. The aim of this study was to determine the prevalence of RH and associated risk factors in Africa. Data sources We conducted a comprehensive search of electronic databases (PubMed, EMBASE, Africa Wide Information and Africa Index Medicus) completed by manual search of articles, regardless of language or publication date. Methods We included studies which have reported the prevalence and/or risk factors for RH in Africa from inception to 19 May 2016. Forest plots were drawn to visualise the combined prevalence of RH and extent of statistical heterogeneity between studies. Results Out of 259 retrieved studies, only 5 from Cameroon, Nigeria, Burkina Faso, Lesotho and Algeria with a total population of 4 068 patients were finally included in this review. There was no study from the Eastern part of Africa. Though the definition of RH was not similar across studies, its prevalence was respectively 11.7%, 4.9%, 14.6%, 14.3% and 19.0%, with an overall pooled prevalence of 12.1% (95% CI 8.0% to 17.7%). Potential risk factors were: non-compliance to treatment, ageing, male sex, dyslipidaemia, metabolic syndrome, previous cardiovascular events, physical inactivity and stress, but not excessive salt intake, alcohol and coffee ingestions. Moreover, diabetes, smoking, obesity and renal insufficiency yielded discrepant results. Conclusions There is a huge dearth of research on the epidemiology of RH in Africa. Thereby, an extensive study of RH prevalence and risk factors is still largely warranted to curtail the high and continuously increasing burden of hypertension across Africa. PMID:27650760
