    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.

    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.

  7. A Bibliometric Analysis of Climate Engineering Research

    Science.gov (United States)

    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.

    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.

  19. Tracking Scientometric Research in Taiwan Using Bibliometric and Content Analysis

    2012-12-01

    Full Text Available his study used bibliometric analysis and content analysis to explore characteristics and trends of scientometric research authored by researchers in Taiwan based on journal articles and theses. The findings indicated that after the first article on scientometrics was published in 1987, an increasing trend was observed in the number of scientometric-related publications after 2000, indicating that scientometric research received more attention in recent years. The scope of disciplines of researchers was broad, and the number of disciplines continued to increase. This confirms the interdisciplinary nature of scientometric research with relationships that cross over different areas. From the perspective of the authors’ disciplines, the largest percentage of the authors were from the fields of library and information science (LIS, followed by business and management, and medical science, but a considerable drop in number was observed in the percentage of LIS. In addition, co-authored articles were dominant. Over half of these articles were classified as inter-institutional collaboration and exhibited a steadily increasing trend. The number of interdisciplinary articles also exhibited an upward trend. Most of the research topics focused on citation analysis and characteristic of literature. The same trends were also found in the top two research methods: general bibliometric analysis and citation analysis. Due to the interdisciplinary nature of scientometric research, the academic backgrounds of the researchers would naturally be diverse. Given this characteristic, this study suggests that the relationship between disciplines of researchers and research topics can be further explored.

    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.

    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.

    2014-01-01

    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 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.

    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.

    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.

  5. Vulnerabilities—bibliometric analysis and literature review of evolving concepts

    Science.gov (United States)

    Giupponi, Carlo; Biscaro, Claudio

    2015-12-01

    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.

    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.

  12. 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.

    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. PMID:26372160

    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.

    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.

    The objective of this paper is to provide a detailed evaluation of type 2 diabetes mellitus research output from 1951-2012, using large-scale data analysis, bibliometric indicators and density-equalizing mapping. Data were retrieved from the Science Citation Index Expanded database, one of the seven curated databases within Web of Science. Using Boolean operators "OR", "AND" and "NOT", a search strategy was developed to estimate the total number of published items. Only studies with an English abstract were eligible. Type 1 diabetes and gestational diabetes items were excluded. Specific software developed for the database analysed the data. Information including titles, authors' affiliations and publication years were extracted from all files and exported to excel. Density-equalizing mapping was conducted as described by Groenberg-Kloft et al, 2008. A total of 24,783 items were published and cited 476,002 times. The greatest number of outputs were published in 2010 (n=2,139). The United States contributed 28.8% to the overall output, followed by the United Kingdom (8.2%) and Japan (7.7%). Bilateral cooperation was most common between the United States and United Kingdom (n=237). Harvard University produced 2% of all publications, followed by the University of California (1.1%). The leading journals were Diabetes, Diabetologia and Diabetes Care and they contributed 9.3%, 7.3% and 4.0% of the research yield, respectively. In conclusion, the volume of research is rising in parallel with the increasing global burden of disease due to type 2 diabetes mellitus. Bibliometrics analysis provides useful information to scientists and funding agencies involved in the development and implementation of research strategies to address global health issues.

    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.

    Middle East Respiratory Syndrome (MERS), a pandemic threat to human beings, has aroused huge concern worldwide, but no bibliometric studies have been conducted on MERS research. The aim of this study was to map research productivity on the disease based on the articles indexed in PubMed. The articles related to MERS dated from 2012 to 2015 were retrieved from PubMed. The articles were classified into three categories according to their focus. Publication outputs were assessed and frequently used terms were mapped using the VOS viewer software. A total of 443 articles were included for analysis. They were published in 162 journals, with Journal of Virology being the most productive (44 articles; 9.9%) and by six types of organizations, with universities being the most productive (276 articles; 62.4%).The largest proportion of the articles focused on basic medical sciences and clinical studies (47.2%) and those on prevention and control ranked third (26.2%), with those on other focuses coming in between (26.6%). The articles on prevention and control had the highest mean rank for impact factor (IF) (226.34), followed by those on basic medical sciences and clinical studies (180.23) and those on other focuses (168.03). The mean rank differences were statistically significant (p = 0.000). Besides, “conronavirus”, “case”, “transmission” and “detection” were found to be the most frequently used terms. The findings of this first bibliometric study on MERS suggest that the prevention and control of the disease has become a big concern and related research should be strengthened. PMID:27304963

    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

    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.

    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.

  19. Bibliometric analysis of global environmental assessment research in a 20-year period

    International Nuclear Information System (INIS)

    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

    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.

    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

METHODOLOGY/PRINCIPAL FINDINGS: A bibliometric analysis (1991-2005. Data sources included papers published by authors from each country separately. The 25 European countries produce less than 1/3 health literacy research when compared to the U.S. (13,710 and 49,523 articles were published by authors with main affiliation in the European Union and the four candidate countries, and the U.S., respectively. The Netherlands and Sweden (followed by Germany, Italy, and France are the European countries with the highest number of research published in fields related to health literacy. After adjustment for population Sweden, Finland, and Norway, were on the top of the relevant list. In addition, Sweden, Finland, and Ireland, were on the top of the list of countries regarding research productivity on the selected fields after adjustment for gross domestic product (GDP. CONCLUSIONS/SIGNIFICANCE: Inequalities in research published on the topic of health literacy exist among Europe, Norway, Switzerland, and the U.S. More research may need to be done in all areas of health literacy in Europe and the potential detrimental effects of this gap should be further investigated.

    Infectious diseases research in a low-income country like Afghanistan is important. Methods: In this study an internet-based database Pubmed was used for bibliometric analysis of infectious diseases research activity. Research publications entries in PubMed were analysed according to number of publications, topic, publication type, and country of investigators. Results: Between 2002-2011, 226 (77.7%) publications with the following research topics were identified: respiratory infections 3 (1.3%); parasites 8 (3.5%); diarrhoea 10 (4.4%); tuberculosis 10 (4.4%); human immunodeficiency virus (HIV) 11(4.9%); multi-drug resistant bacteria (MDR) 18(8.0%); polio 31(13.7%); leishmania 31(13.7%); malaria 46(20.4%). From 2002-2011, 11 (4.9%) publications were basic science laboratory-based research studies. Between 2002-2011, 8 (3.5%) publications from Afghan institutions were identified. Conclusion: In conclusion, the internet-based database Pubmed can be consulted to collect data for guidance of infectious diseases research activity of low-income countries. The presented data suggest that infectious diseases research in Afghanistan is limited for respiratory infections research, has few studies conducted by Afghan institutions, and limited laboratory-based research contributions.

    Full Text Available Objectives: Evaluate the production and the research collaborative network on Leishmaniasis in South America. 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.

    International Nuclear Information System (INIS)

    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

  14. Balkanized Research in Ecological Engineering Revealed by a Bibliometric Analysis of Earthworms and Ecosystem Services

    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.

    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.

    Congenital heart disease (CHD) is the most common congenital anomaly, affecting 1 % of live births. The field of pediatric cardiology has witnessed major advances over the past 25 years triggered by research initiatives focusing on CHD. However, large disparities exist in research capabilities between Arab developing nations and the developed nations. This study used bibliometric analysis to assess the contribution of the Arab countries to CHD research. To identify articles on CHD published in the Arab countries, the United States, and Europe, a systematic search was run on MEDLINE, PubMed, and Scopus. The Arab countries, with an estimated population of 362 million, published 530 research articles addressing CHD in the last 25 years (average, 1.5 articles/10(6) population). This compares with 12,936 research articles published in the United States (average, 41 articles/10(6) population) and 12,260 published in Europe (average, 24.3 articles/10(6) population). Basic research relating to genetics and animal models of CHD is emerging sparsely in the Arab world, with few articles published in high-impact-factor journals. The Arab world research output in the field of CHD per capita is substantially low, estimated to be 29 times less than in developed countries. Despite the minimal increase in published research articles in global periodicals, most of the research relating to CHD continues to be far from innovative. Regional collaborations with international linkage are starting to evolve. The research facilities in the Arab countries need to increase substantially in research and infrastructure funding to keep up with the pace of research in developing countries. PMID:22878810

    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.)

    Bibliometric studies are increasingly being used for research assessment. Bibliometric indicators are strongly methodology-dependent but for all of them, various types of data normalization are an indispensable requirement. Bibliometric studies have many pitfalls; technical skill, critical sense...... and a precise knowledge about the examined scientific domain are required to carry out and interpret bibliometric investigations correctly.

    This study aimed to identify and to analyze characteristics of top-cited articles published in the Web of Science chemical engineering subject category from 1899 to 2011. Articles that have been cited more than 100 times were assessed regarding publication outputs, and distribution of outputs in journals. Five bibliometric indica- tors were used to evaluate source countries, institution and authors. A new indicator, Y-index, was created to assess quantity and quality of contribution to articles. Results showed that 3828 articles, published between 1931 and 2010, had been cited at least 100 times. Among them 54% published before 1991, and 49% top-cited articles originated from US. The top eight productive institutions were all located in US. The top journals were Journal of Catalysis, AIChE Journal, Chemical Engineering Science and Journal of Membrane Science. Y-index was successfully ap- plied to evaluate publication character of authors, institutions, and countries/regions.

    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. The article concludes with several suggestions for authors, journal editors, and science policy institutions.

    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.

    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.

  18. 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...

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

    2014-09-01

    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 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.

    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. PMID:26529270

    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.

    2009-03-01

    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

Despite using different methods and tools, the objectives commonly propose to develop the science and characterization of the production in different areas. This paper is aimed with two objectives related to two different areas of the bibliometrics, evaluative and descriptive, characterizing its differential. The general objective consists in the analysis and understanding of the characteristics of the works published in the Congress ANPCONT, and the specific objectives are the showing of the authors’ profile, of the productions and use the of the references. The methods used are bibliometrics and, for the descriptive analysis it is applied the Lotka Law, which determines the productivity of the authors. For the evaluative analysis it is applied the study of the typology of the references used. As a result, in respect to the authors profile, thy are, in general, connected to the academy, professors and doctors, with predominance of author from Universidade de São Paulo, Fucape Business School and Universidade Regional de Blumenau. In respect to the descriptive analysis, the production does not adjust to the Lotka Law, and in respect to the evaluative analysis is observed that there is a predominance of use of international papers in the researches. It is concluded that the production demonstrated a development during the years, and some authors, universities and states are highlighted in the congress production.

    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.

    2009-10-01

    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.

    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.

    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.

  14. 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.

A total of 610 articles from 1882 to 2008 and 113 theses and dissertations from 1971 to 2008 were identified and analyzed. The growth of literature, research subjects, author productivity, the distribution of journals and organizations are addressed. The results of this study reveal that the journal articles in Taiwan had been up-growing except after 2003, but the theses and dissertations had been growing stably. The major research subject of journal articles is classification theory and descriptive cataloging, but the theses and dissertations are knowledge organization. The zone analysis from Bradford’s law is not applicable to journal productivity. Productivity is mainly focused on single author and toward coauthor. The Journal of Educational Media and Library Sciences is the major journal that publishes information organization articles. The National Taiwan University is the most productive schools of theses and dissertations, but various schools have their characteristics of research subjects. [Article content in Chinese

  1. Neuroethics 1995–2012. A Bibliometric Analysis of the Guiding Themes of an Emerging Research Field

    Leefmann, Jon; Levallois, Clement; Hildt, Elisabeth

    2016-01-01

    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.

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

    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.

  5. A Systematic Review of Perennial Staple Crops Literature Using Topic Modeling and Bibliometric Analysis

    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.

  6. 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.

    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 ...

    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. PMID:26989272

    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.

    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.

  8. 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...

    Firm-level data for the manufacturing sector in Africa, presented in this paper, shows very low levels of investment. A positive effect from profits onto investment is identified in a flexible accelerator specification of the investment function controlling for firm fixed effects. There is evidence that this effect is confined to smaller firms. A comparison with other studies shows that, for such firms, the profit effect is much smaller in Africa than in other countries. Reasons for the relat...

    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.

    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.

    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.

    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

    2000-01-01

    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.

    2016-04-01

    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.

    Khaleque, Abdul

    2016-01-01

    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.

    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.

    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.

    2013-01-01

    A relevant question for the organization of large scale research assessments is whether bibliometric evaluation and informed peer review where reviewers know where the work was published, yield similar results. It would suggest, for instance, that less costly bibliometric evaluation might - at least partly - replace informed peer review, or that bibliometric evaluation could reliably monitor research in between assessment exercises. We draw on our experience of evaluating Italian research in ...

    Full Text Available The increasing number of scientific journals, especially over thelast 20 years, created the need for methodologies based on simple metrics, to accurately capture the “quality” of those journals and their impact on the scientific community. Especially in the case of journals from the field of forestry, relatively little work has been conducted on providing valid journal classifications. In this paper we attempt to assess the impact of journals from this field in terms of bibliometric data. In addition to the already proposed metrics (complementary to the journal h-index, we also apply a new measureto rank journals, that provides a more balanced evaluation of the journal performance, by adjusting for various biases affecting the h-index. We examined the relationships between various bibliometric indicators proposed for assessing the journal impact and wo found high correlations between most indices, with only few exceptions. According to citation analysis, Canadian Journal of Forest Research, Journal of Vegetation Science, Forest Science, Tree Physiology, International Journal of Wildland Fire, Holzforschung, Trees-Structure and Function, Silva Fennica, Agricultural and Forest Meteorology and Wood and Fiber Science are the top forestry journals.These publish articles related to all the domains of forestry science. More specialized journals are also included, dealing with specific issues of scientific interest and also of major importance to the scientific community.

  13. Radiological research in Europe: a bibliometric study.

    Science.gov (United States)

    Mela, G S; Martinoli, C; Poggi, E; Derchi, L E

    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

    Database Tomography (DT) is a textual database analysis system consisting of two major components: (1) algorithms for extracting multi-word phrase frequencies and phrase proximities (physical closeness of the multi-word 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 Power Sources database derived from the Science Citation Index. Phrase frequency analysis by the technical domain experts provided the pervasive technical themes of the Power Sources database, and the phrase proximity analysis provided the relationships among the pervasive technical themes. Bibliometric analysis of the Power Sources literature supplemented the DT results with author/journal/institution/country publication and citation data. (author)

    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

Being objective and easy to operate, it is widely used in academic research and evaluation. Based on the database of Scopus, this paper conducts a bibliometric evaluation of the academic performance of major university disciplines in Shanghai. The findings are summarized as follows: From the single perspective of citation indicator analysis, the academic performance of major university disciplines in Shanghai is better in Scopus than in WoS. With other relevant bibliometric indicators, problems concerning university discipline development in Shanghai become prominent, such as the irrational structure of advantageous disciplines and newly -emerging disciplines, and the lack of discipline planning at the macro level. Therefore, in the evaluation of academic performance of disciplines, a comprehensive analysis should be conducted based on a combination of citation indicators and other bibliometric indicators.

The study is to identify the status and trend of this hot topic across disciplines. Bibliometrics is em-ployed in this paper to analyze the publication pattern of regional inequality research. As a research method used in library and information sciences, bib-liometrics has been widely applied to analyze the pattern of literature and trend of a given topic or subject. It can be used for in-depth reviews of re-search themes for better guidance for follow-up studies. Based on 3528 publica-tions indexed in the SCIE/SSCI databases during 1990-2012, the study reveals that Harvard university and University of California Los Angeles are major re-search institutions in this area. USA ranks as the top country in the publica-tions of this topic both qualitatively and quantitatively. China's publications on regional inequality research lag far behind that of USA and UK, and the quality should be improved. The world interests on Asia and China make the o-verseas Chinese scholars an important role in this research field.

    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.

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.

    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.

    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 The use of information and communication technologies (ICT tools to improve the efficiency of professionalism at work is increasing every time under the dynamic digital environment. Tools such as telemedicine, tele-education, and health informatics have of late been incorporated in the health sector to enable easy access to essential services, for example, in medical areas from referral centers by the patients on one hand and enabling the doctor to doctor consultations for the benefit of patients. Unfortunately, observations indicate dearth efforts and commitment to optimize use of the tools in the majority of the countries south of the Sahara. Sub-Saharan Africa has been left almost behind the rest of the world in terms of development going through decades of economic exploitation by especially the west through its natural and human resources. These factors, ethnic conflicts and endless wars have continued to ruin sub-Saharan Africa′s socio-economic development. Information was obtained through a network of telemedicine practitioners in different African countries using internet communication, through E-mail and reviewing existing literature of their activities. This information was compiled from representative countries in each African region and the previous authors′experiences as telemedicine practioners. Most of these countries have inadequate ICT infrastructure, which yet creates sub-optimal application. Sub-Saharan Africa, made up of 33 of the 48 global poorest countries has to extend its ICT diffusion and policy to match the ever developing global economy. In some countries such as Ethiopia and South Africa there is significant progress in Telemedicine while in countries such as Burkina Faso and Nigeria the progress is slow because of lack of political support. Almost all reference to Africa is made in due respect to sub-Saharan Africa, one with big social, economic, and political problems with resultant high morbidity and mortality

    Detecting emerging trend topics from lots of papers is one of the difficulties for information research. This paper put forward e-merging trend analysis based on bibliometric method. Firstly,this paper used co-citation method to find out burst cited references and then downloaded their citing papers as data source for the following analysis. This paper used two indexes( attention and practicality) to detect emerging trend topics. The " attention" index through the high frequent keywords was used to create co-occurrence matrix and visualiza-tion,summing up the emerging trend topics; the " practicality" index through the countries,organizations and average impact factor,was used to evaluate whether the selected emerging trend topics meet the demands.

    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.

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.

    Full Text Available The Organization of Knowledge is an area of multiple applications and very traditional in research / teaching in Information Science. Most of the literature deals with the process, activities and tools specially developed for the treatment of documents for storage, dissemination, retrieval and use of information systems and services. This paper presents a bibliometric analysis of scientific activity in the field of Knowledge Organization, using publications database ISI Web of Science - WoS. The importance of bibliometric study is underpinned by the need to understand and evaluate and measure research productivity and authors, allowing the detection of designs and patterns on the Organization of Knowledge. The methodological procedures are exploratory-descriptive and some steps have been established to better deployment: a literature review to support the research, identification database, preparation of expression search, data collection, organization and bibliometric treatment with Vantage Point software and finally graphical representations with the aid of Microsoft Excel. Among the search results, it is noteworthy that in 20 years there is a steady growth of scientific publications on Knowledge Organization and the country that leads the ranking of the fastest publish on the subject is Canada, Brazil being the eighth.

    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

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

    Directory of Open Access Journals (Sweden)

    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

    Background The past two decades have seen a large increase in investment in global public health research. There is a need for increased coordination and accountability, particularly in understanding where funding is being allocated and who has capacity to perform research. In this paper, we aim to assess global, regional, national and sub–national capacity for public health research and how it is changing over time in different parts of the world. Methods To allow comparisons of regions, countries and universities/research institutes over time, we relied on Web of ScienceTM database and used Hirsch (h) index based on 5–year–periods (h5). We defined articles relevant to public health research with 98% specificity using the combination of search terms relevant to public health, epidemiology or meta–analysis. Based on those selected papers, we computed h5 for each country of the world and their main universities/research institutes for these 5–year time periods: 1996–2000, 2001–2005 and 2006–2010. We computed h5 with a 3–year–window after each time period, to allow citations from more recent years to accumulate. Among the papers contributing to h5–core, we explored a topic/disease under investigation, “instrument” of health research used (eg, descriptive, discovery, development or delivery research); and universities/research institutes contributing to h5–core. Results Globally, the majority of public health research has been conducted in North America and Europe, but other regions (particularly Eastern Mediterranean and South–East Asia) are showing greater improvement rate and are rapidly gaining capacity. Moreover, several African nations performed particularly well when their research output is adjusted by their gross domestic product (GDP). In the regions gaining capacity, universities are contributing more substantially to the h–core publications than other research institutions. In all regions of the world, the topics of articles

    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 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...

    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

    Ikechi G Okpechi

    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

    Fernández Raga, M. B.

    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

    2014-12-01

    Full Text Available Background: Nursing education reform is identified as an important strategy for enhancing health workforce performance, and thereby improving the functioning of health systems. Globally, a predominant trend in such reform is towards greater professionalisation and university-based education. Related nursing education reform in South Africa culminated in a new Framework for Nursing Qualifications in 2013. Objective: We undertook a policy analysis study of the development of the new Nursing Qualifications Framework in South Africa. Design: We used a policy analysis framework derived from Walt and Gilson that interrogated the context, content, actors, and processes of policy development and implementation. Following informed consent, in-depth interviews were conducted with 28 key informants from national and provincial government; the South African Nursing Council; the national nursing association; nursing academics, managers, and educators; and other nursing organisations. The interviews were complemented with a review of relevant legislation and policy documents. Documents and interview transcripts were coded thematically using Atlas-ti software. Results: The revision of nursing qualifications was part of the post-apartheid transformation of nursing, but was also influenced by changes in the education sector. The policy process took more than 10 years to complete and the final Regulations were promulgated in 2013. The two most important changes are the requirement for a baccalaureate degree to qualify as a professional nurse and abolishing the enrolled nurse with 2 years training in favour of a staff nurse with a 3-year college diploma. Respondents criticised slow progress, weak governance by the Nursing Council and the Department of Health, limited planning for implementation, and the inappropriateness of the proposals for South Africa. Conclusions: The study found significant weaknesses in the policy capacity of the main institutions

    使用共词分析法,本研究绘制了2000—2004年度和2005—2009年度国内心理学论文所表征的研究领域的战略坐标图,通过提取两个时问段内被CNKI收录的核心期刊论文所标引的关键词,并借助因子分析、聚类分析,发现高频词明显增多、研究热点出现变化。结论指出:学科内部结构正在发生变化、研究范围进一步拓展、实证主义仍是主流研究方法取向、核心成熟的研究类团仍待出现。%This article is to present the ongoing intellectual structure of psychological research in China. 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",

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

    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.

  20. The interannual variability of Africa's ecosystem productivity: a multi-model analysis

    2009-02-01

    Full Text Available We are comparing spatially explicit process-model based estimates of the terrestrial carbon balance and its components over Africa and confront them with remote sensing based proxies of vegetation productivity and atmospheric inversions of land-atmosphere net carbon exchange. Particular emphasis is on characterizing the patterns of interannual variability of carbon fluxes and analyzing the factors and processes responsible for it. For this purpose simulations with the terrestrial biosphere models ORCHIDEE, LPJ-DGVM, LPJ-Guess and JULES have been performed using a standardized modeling protocol and a uniform set of corrected climate forcing data.

    While the models differ concerning the absolute magnitude of carbon fluxes, we find several robust patterns of interannual variability among the models. Models exhibit largest interannual variability in southern and eastern Africa, regions which are primarily covered by herbaceous vegetation. Interannual variability of the net carbon balance appears to be more strongly influenced by gross primary production than by ecosystem respiration. A principal component analysis indicates that moisture is the main driving factor of interannual gross primary production variability for those regions. On the contrary in a large part of the inner tropics radiation appears to be limiting in two models. These patterns are partly corroborated by remotely sensed vegetation properties from the SeaWiFS satellite sensor. Inverse atmospheric modeling estimates of surface carbon fluxes are less conclusive at this point, implying the need for a denser network of observation stations over Africa.

    Full Text Available Sesame is an important oil crop widely cultivated in Africa and Asia. Understanding the genetic diversity of accessions from these continents is critical to designing breeding methods and for additional collection of sesame germplasm. To determine the genetic diversity in relation to geographical regions, 96 sesame accessions collected from 22 countries distributed over six geographic regions in Africa and Asia were genotyped using 33 polymorphic SSR markers. Large genetic variability was found within the germplasm collection. The total number of alleles was 137, averaging 4.15 alleles per locus. The accessions from Asia displayed more diversity than those from Africa. Accessions from Southern Asia (SAs, Eastern Asia (EAs, and Western Africa (WAf were highly diversified, while those from Western Asia (WAs, Northern Africa (NAf, and Southeastern Africa (SAf had the lowest diversity. The analysis of molecular variance revealed that more than 44% of the genetic variance was due to diversity among geographic regions. Five subpopulations, including three in Asia and two in Africa, were cross-identified through phylogenetic, PCA, and STRUCTURE analyses. Most accessions clustered in the same population based on their geographical origins. Our results provide technical guidance for efficient management of sesame genetic resources in breeding programs and further collection of sesame germplasm from these different regions.

  4. 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...

    2001-01-01

    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.

    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.

    After the drought of the 1970s in West Africa, the variability in rainfall and land use changes mostly affected flow, and recently flooding has been said to be an increasingly common occurrence throughout the whole of West Africa. These changes have raised many questions about the impact of climate change on the flood regimes in West African countries. This paper investigates whether floods are becoming more frequent or more severe and to what extent climate patterns have been responsible for these changes. We analyzed the trends in the floods occurring in 11 catchments within West Africa's main climate zones. The methodology includes two methods for sampling flood events, namely the AM (annual maximum) method and the POT (peak over threshold), and two perspectives of analysis are presented: long-term analysis based on two long flood time series and a regional perspective involving 11 catchments with shorter series. The Mann-Kendall trend test and the Pettitt break test were used to detect nonstationarities in the time series. The trends detected in flood time series were compared to the rainfall index trends and vegetation indices using contingency tables in order to identify the main driver of change in flood magnitude and flood frequency. The relation between the flood index and the physiographic index was evaluated through a success criterion and the Cramer criterion calculated from the contingency tables. The results show the existence of trends in flood magnitude and flood frequency time series, with two main patterns. Sahelian floods show increasing flood trends and one Sudanian. catchment presents decreasing flood trends. For the overall catchments studied, trends in the maximum 5-day consecutive rainfall index (R5d) show good coherence with trends in flood, while the trends in normalized difference vegetation indices (NDVIs) do not show a significant agreement with flood trends, meaning that this index has possibly no impact on the behavior of floods in

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

    Directory of Open Access Journals (Sweden)

    G. Naumann

    2013-10-01

    Full Text Available 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

    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.

    There is increasing interest to control or eradicate the major neglected tropical diseases. Accurate modelling of the geographic distributions of parasitic infections will be crucial to this endeavour. We used 664 community level infection prevalence data collated from the published literature in conjunction with eight environmental variables, altitude and population density, and a multivariate Bayesian generalized linear spatial model that allows explicit accounting for spatial autocorrelation and incorporation of uncertainty in input data and model parameters, to construct the first spatially-explicit map describing LF prevalence distribution in Africa. We also ran the best-fit model against predictions made by the HADCM3 and CCCMA climate models for 2050 to predict the likely distributions of LF under future climate and population changes. We show that LF prevalence is strongly influenced by spatial autocorrelation between locations but is only weakly associated with environmental covariates. Infection prevalence, however, is found to be related to variations in population density. All associations with key environmental/demographic variables appear to be complex and non-linear. LF prevalence is predicted to be highly heterogenous across Africa, with high prevalences (>20%) estimated to occur primarily along coastal West and East Africa, and lowest prevalences predicted for the central part of the continent. Error maps, however, indicate a need for further surveys to overcome problems with data scarcity in the latter and other regions. Analysis of future changes in prevalence indicates that population growth rather than climate change per se will represent the dominant factor in the predicted increase/decrease and spread of LF on the continent. We indicate that these results could play an important role in aiding the development of strategies that are best able to achieve the goals of parasite elimination locally and globally in a manner that may also account

  11. Price and income elasticities of crude oil import demand in South Africa: A cointegration analysis

    International Nuclear Information System (INIS)

    This paper examines the demand for imported crude oil in South Africa as a function of real income and the price of crude oil over the period 1980-2006. We carried out the Johansen co integration multivariate analysis to determine the long-run income and price elasticities. A unique long-run cointegration relationship exists between crude oil imports and the explanatory variables. The short-run dynamics are estimated by specifying a general error correction model. The estimated long-run price and income elasticities of -0.147 and 0.429 suggest that import demand for crude oil is price and income inelastic. There is also evidence of unidirectional long-run causality running from real GDP to crude oil imports. - Research Highlights: →The paper examines the demand for imported crude oil in South Africa over the period 1980-2006. → The estimated long-run price and income elasticities are -0.147 and 0.429, respectively. → There is evidence of unidirectional long-run causality running from real GDP to crude oil imports.

    Objective: This study used a bibliometric analysis to explore the research development of schizo-phrenia nursing in China from 2010 to 2014. Methods: The CNKI, VIP, and CBM databases were used to retrieve articles in China descri-bing schizophrenia nursing that met the predefined criteria from 2010 to 2014. Altogether, 1486 articles were included and analyzed by bibliometric methods. Results: The area of schizophrenia nursing had an annual average publication of 351 papers. The most productive institutions in schizophrenia nursing were located in Guangdong, Jiangsu, and Shandong, followed by Henan and Zhejiang. The papers were mainly published in the Medical Journal of Chinese People’ s Health and then in the International Journal of Nursing and the Chi-nese Journal of Modern Nursing. The study subjects mainly were on schizophrenics and then care-givers of schizophrenics ( including families, nursing assistant, nurse) . The most often used study designs in schizophrenia nursing research were a quasi-experimental study followed by experience reports and an investigational study. The research topics mainly focused on nursing intervention and rehabilitation training, followed by psychological, quality of life and social function. Conclusions: The schizophrenia nursing research has rapidly developed, with extensive content and abundant study topics, over the past 5 years.

  14. Seismic Analysis of Magmatism in the Galapagos Archipelago and East Africa

    Science.gov (United States)

    Tepp, Gabrielle

    Magmatism and deformation are consequences of fundamental processes shaping Earth's ˜150 km-thick continental and three different seismic methods to probe magma migration and storage and tectonism in two intraplate hotspot provinces: the Galapagos and East Africa. First, seismic body-wave tomography is used to image magma within oceanic crust of the largest Galapagos volcano, Sierra Negra. A laterally large, low-velocity region with many smaller, high-magnitude velocity anomalies is imaged at 8--15.5 km depths. No sharp seismic velocity increase is imaged within the resolvable depths, indicating that the thickened crust is at least 16 km deep. The second study involves a spectral analysis of earthquakes induced by the intrusion of thin sheets of magma rising beneath the Afar rift, East Africa. Earthquakes have varying spectral content, some with unusually large amplitude low-frequency content and enhanced surface waves. The analysis showed no clear boundaries between spectral types, suggesting that they are all primarily the result of brittle failure. Deep dike segments (tops > 3 km) induce only high-frequency volcano-tectonic earthquakes, while shallower dike segments induce the full range of spectral types. This suggests that low-frequency content is a result of shallow hypocenters, with path and site effects, surface ruptures, and dike fluid interactions all possible secondary causes. In the final study, shear-wave splitting analysis of teleseismic body-wave phases is conducted to evaluate strain and crack fabrics at the base of the continental plate as a consequence of magmatism, mantle flow, and plate stretching in the Western rift, East Africa. On average, fast directions are northeast, consistent with geodynamic models of mantle flow from the African superplume and passive rifting. In the northern study area, splitting directions become complex and rotate northwest. The variational splitting in this region is likely due to mantle flow complexities caused by

    Background The poor genomics research capacity of Sub-Saharan Africa (SSA) could prevent maximal benefits from the applications of genomics in the practice of medicine and research. The objective of this study is to examine the author affiliations of genomic epidemiology publications in order to make recommendations for building local genomics research capacity in SSA. Design SSA genomic epidemiology articles published between 2004 and 2013 were extracted from the Human Genome Epidemiology (HuGE) database. Data on authorship details, country of population studied, and phenotype or disease were extracted. Factors associated with the first author, who has an SSA institution affiliation (AIAFA), were determined using a Chi-square test and multiple logistic regression analysis. Results The most commonly studied population was South Africa, accounting for 31.1%, followed by Ghana (10.6%) and Kenya (7.5%). About one-tenth of the papers were related to non-communicable diseases (NCDs) such as cancer (6.1%) and cardiovascular diseases (CVDs) (4.3%). Fewer than half of the first authors (46.9%) were affiliated with an African institution. Among the 238 articles with an African first author, over three-quarters (79.8%) belonged to a university or medical school, 16.8% were affiliated with a research institute, and 3.4% had affiliations with other institutions. Conclusions Significant disparities currently exist among SSA countries in genomics research capacity. South Africa has the highest genomics research output, which is reflected in the investments made in its genomics and biotechnology sector. These findings underscore the need to focus on developing local capacity, especially among those affiliated with SSA universities where there are more opportunities for teaching and research.

    2014-01-01

    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.

    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.

    Objective]In order to summarize the research history, understand the frontiers and focus and provide a sound foundation for researchers and policy-makers, the comparative analysis of world literature and patents about technology innovation of livestock was carried out.[Method]Based on Science Citation Index and Derwent Innovation Index database, with bibliometric methods, relevant literature and patents on livestock breeding during the years of 1964 and 2014 were collected. Thomson Data Analyzer, Thomson Innovation, OSviewer and other tools were used.[Result]Studies on livestock breeding technology have gone through three stages: the start-up and slowly developing phase lasted from 1960 to 1990, focusing on performance determination evaluation; the rapid growth phase lasted from 1990 to 2000, with the wide use of BLUP breeding, artificial insemination, superovulation and embryo transfer technology,the leaping forward phase began in 2000 till now, gender control technology; molecular markers and genomic selection technology boost the development of research, but the patent application experienced fluctuations in the past decade. The United States possesses the prominent capability in the field all over the world, reflected by the amount of paper issued, citations, and European developed countries and Japan have long occupied a leading position while research from China go through a rapid development in recent years, particularly in terms of patents, but the quality of Chinese research needs to be improved according to the average citation. Ten out of top 20 patent applicators are from US, all of which are enterprises while China has 4 universities and institutions in the top 20, indicating that innovation system with the enterprises as the mainstay has not been established in China. Cattle and pigs have been the focus in the field. Research on cattle developed in 1990’s, but was catch up by that on pig after 2000; and research on sheep has a rapid and consistent

    Counting citations that a research article received by other articles was the traditional bibliometric method for the evaluation of a scientific research. Citations have been used both to evaluate a scientific paper - usually in conjunction with the peer review methods - and to determine the quality of a scientific research output. The development of tools even more Web 2.0 oriented has profoundly changed the scientific communication process. In this context, many web tools have emerged including the so-called "social media" (e-i., Facebook, Twitter). Hence the need for new indicators to measure the influence of these tools on the scientific community and the emergence of alternative metrics. Altmetrics combines the traditional bibliometrics tool with the use of the web. Formulated with the purpose to measure new aspects of scientific production, these new metrics are placed in order to complement and supplement the existing indicators rather than act as their replacements.

    Bibliometry is a quantitative statistical technique to measure levels of production and dissemination of knowledge, as well as a useful tool to track the development of an scientific area. The valuation of production required for recognition of researchers and magazines is accomplished through tools called bibliometric indexes, divided into quality indicators and scientific impact. Initially developed for monographs of statistical measures especially in libraries, today bibliometrics is mainly used to evaluate productivity of authors and citation repercussion. However, these tools have limitations and sometimes provoke controversies about indiscriminate application, leading to the development of newer indexes. It is important to know the most common search indexes and use it properly even acknowledging its limitations as it has a direct impact in their daily practice, reputation and funds achievement.

    Pigs harbor a variety of viruses that are closely related to human viruses and are suspected to have zoonotic potential. Little is known about the presence of viruses in smallholder farms where pigs are in close contact with humans and wildlife. This study provides insight into viral communities and the prevalence and characteristics of enteric viral co-infections in smallholder pigs in East Africa. Sequence-independent amplification and high-throughput sequencing were applied to the metagenomics analysis of viruses in feces collected from asymptomatic pigs. A total of 47,213 de novo-assembled contigs were constructed and compared with sequences from the GenBank database. Blastx search results revealed that 1039 contigs (>200 nt) were related to viral sequences in the GenBank database. Of the 1039 contigs, 612 were not assigned to any viral taxa because they had little similarity to known viral genomic or protein sequences, while 427 contigs had a high level of sequence similarity to known viruses and were assigned to viral taxa. The most frequent contigs related to mammalian viruses resembling members of the viral genera Astrovirus, Rotavirus, Bocavirus, Circovirus, and Kobuvirus. Other less abundant contigs were related to members of the genera Sapelovirus, Pasivirus, Posavirus, Teschovirus and Picobirnavirus. This is the first report on the diversity of the fecal virome of pig populations in East Africa. The findings of the present study help to elucidate the etiology of diarrheal diseases in pigs and identify potential zoonotic and emerging viruses in the region. Further investigations are required to compare the incidence of these viruses in healthy and diseased pigs in order to better elucidate their pathogenic role. PMID:26965436

    George A. Thopil

    2010-10-01

    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.

    2010-03-01

    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.

    2007-10-01

    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.

    2009-03-01

    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.

  10. Do they agree? Bibliometric evaluation vs informed peer review in the Italian research assessment exercise

    CERN Document Server

    Alberto, Baccini

    2015-01-01

    During the Italian research assessment exercise, the national agency ANVUR performed an experiment to assess agreement between grades obtained through informed peer review (IR) and bibliometrics. A sample was evaluated by using both methods and concordance was analyzed by weighted Cohen's kappas. According to ANVUR results indicated an overall "more than adequate" agreement which "fully justifies" the choice of using jointly both techniques in the assessment. However, according to available statistical guidelines for kappa values, the degree of agreement has to be interpreted, for all research fields, as poor or, in a few cases, as, at most, fair. The only notable exception is Area 13 (economics and statistics) and its sub-areas, showing moderate agreement. However, a statistical meta-analysis rejects the hypothesis that kappas from Area 13 share the same distribution as those from the other areas. In fact, a scrutiny of the experiment protocol adopted by the Area 13 panel highlights substantial modifications...

This sstudy examined the positive and negative implications of science and technology in Africa using Nigeria as a case study. This attempt became germane owing to the important place of the scientific and technological enterprise in the entire pattern of human life. The critical and conceptual methods of analysis were employed and the available literatures on the problem provided the background for the study. The study showed the dangers in uncontrolled destructive character of scientific and technological knowledge to human survival and suggested appropriate control measures. The study, therefore, suggested resource control, the control of chemical and biological weapons and the abuse of information and communication technology. Manufacturers of various technologies needed to create subsidiary technology and put in place necessary mechanisms for curtailing the foreseeable consequences of their products. Indeed, technological civilization should not be blindly embraced.

    Since the mid-1990s, Sub-Saharan Africa has experienced unprecedented levels of high economic growth. A key question follows: What accounts for the turnaround of the growth performance in the mid-1990s? The answer can provide insight into whether the recent growth spurt in Sub-Saharan Africa is merely temporary or the beginning of a sustainable takeoff. This paper examines the sources of g...

    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

    High and rising levels of crime plague post-apartheid South Africa. A common explanation for these high crime rates relates the country’s unique socio-political past to a system of ineffective social control mechanisms that suggest high levels of social disorganisation within certain communities. Other explanations emphasise the presence of disaffected youths and deprivation, as well as the rapid immigration of people from neighbouring African countries into South Africa. I examined a number ...

    After twenty years of democracy, the most pressing problem facing South Africa is the absence of sustainable economic growth and job creation. Since 1994, major economic reforms and adjustments have been made, which were seen as a requirement for achieving economic growth and development. However, despite these efforts, unemployment in South Africa remains a challenging problem. The main objectives of the study are, firstly, to examine South Africa’s economic policy initiatives implemented...

    National and international diffusion, composition of the collective of authors who publish in the journal, and cocitation were studies for the journal An. Med. Interna. Diffusion was analyzed by examining the presence of the journal in medical data bases and specialized libraries in Spain. The institutional affiliations and geographical location of authors were determined on the basis of the affiliations given in the article by-lines. The journal is included in the major medical data bases and in approximately 80% of the libraries studied. The predominant professional affiliation among authors was clinical (hospital); the geographical origin of the authors (expressed as a percentage of all authors) approximately paralleled the volume of scientific publications generated by each of Spain's 17 autonomous regions. The cocitation study showed that An. Med. Interna ranked somewhere in the middle of the group' of 38 Spanish medical journals considered representative of research being done in Spain.

    West Africa is currently witnessing the most extensive Ebola virus (EBOV) outbreak so far recorded. Until now, there have been 27,013 reported cases and 11,134 deaths. The origin of the virus is thought to have been a zoonotic transmission from a bat to a two-year-old boy in December 2013 (ref. 2). From this index case the virus was spread by human-to-human contact throughout Guinea, Sierra Leone and Liberia. However, the origin of the particular virus in each country and time of transmission is not known and currently relies on epidemiological analysis, which may be unreliable owing to the difficulties of obtaining patient information. Here we trace the genetic evolution of EBOV in the current outbreak that has resulted in multiple lineages. Deep sequencing of 179 patient samples processed by the European Mobile Laboratory, the first diagnostics unit to be deployed to the epicentre of the outbreak in Guinea, reveals an epidemiological and evolutionary history of the epidemic from March 2014 to January 2015. Analysis of EBOV genome evolution has also benefited from a similar sequencing effort of patient samples from Sierra Leone. Our results confirm that the EBOV from Guinea moved into Sierra Leone, most likely in April or early May. The viruses of the Guinea/Sierra Leone lineage mixed around June/July 2014. Viral sequences covering August, September and October 2014 indicate that this lineage evolved independently within Guinea. These data can be used in conjunction with epidemiological information to test retrospectively the effectiveness of control measures, and provides an unprecedented window into the evolution of an ongoing viral haemorrhagic fever outbreak.

    2009-01-01

    Full Text Available The developing countries of Africa are in severe hunger of FDI inflows as these are receiving a meager 2.8 percent share of global FDI inflows and just 10 percent of aggregate FDI inflows to the developing world. The present study is an effort to examine the growth of FDI inflows to the two largest recipient regions of Africa, through the computation of compound annual growth rates by fitting an exponential function estimated by ordinary least square method. The study detected that during the last three decades, the growth of FDI inflows remained highest for Algeria and Cape Verde, in Northern Africa and West Africa respectively. Both these countries also remained ahead of the others, in their respective regions in growth of FDI as percentage of gross fixed capital formation. The forecasts of FDI inflows to the representative countries of North and West Africa have been generated by using Double Exponential Smoothing model for the period 2009 to 2020. The adequacy of the model is tested by computing autocorrelation coefficients and Ljung-Box Q statistics. The study revealed that in the ensuing decade, Egypt is expected to grow at the fastest pace as far as FDI inflows are concerned.

    Full Text Available The quality and the representativeness of the first long-term Eddy Covariance measurements in the savanna zone of West Africa were investigated using the energy balance closure and the footprint analysis. The quality and representativeness of the first long-term Eddy Covariance measurements over the West African savanna were investigated using the energy balance closure and the footprint analysis. The analysis covered four contrasting periods such as the complete dry season (January to March 2004, the dry to wet transition period (April to May 2004, the rainy season (June to September 2004 and the wet to dry transition period (October to November 2004.

    The results show that the overall energy balance closure can be considered as satisfactory over the whole dataset. The regression fit between (Rn−G and (H+λE was significant (P<0.05 with a coefficient of determination (r2 of 0.80 and a slope of 0.88, while the intercept was 25W/m2. The energy balance closure was affected by rain during the rainy season (r2=0.69, and by sampling problems during the transition periods (R2 were 0.80 and 0.86, respectively.

    The footprint analysis shows that the fetch ranged between 20 m (daytime and 800 m (nighttime. This range showed that the fetch was adequate and fluxes sampled were representative, especially during the rainy season when the vegetal cover was dominated by crops and grasses with scale length of a few meters. During the dry season when the surface is free from crops and grasses, the measurements were also representative as about 60% of the trees around the station were contributing to the measured fluxes. However, during the transition periods some sampling problems appeared, less than 30% of the trees were contributing to the measured fluxes. The relevance of the dominant wind direction in the representativeness of the measurements was also discussed.

    The phylogenetic relationships of early Pleistocene Homo crania from the South African sites of Swartkrans and Sterkfontein were investigated through cladistic analyses of 99 morphological characters. The Swartkrans Member 1 specimen SK 847 and the Stw 53 cranium from Sterkfontein Member 5A were treated as separate operational taxonomic units (OTUs), distinct from the three species of early Homo-H. erectus, H. habilis, and H. rudolfensis-that are recognized from the Plio-Pleistocene deposits of East Africa. The cladistic analyses differed in the treatment of the South African OTUs (separate Swartkrans and Sterkfontein OTUs vs. a single Swartkrans+Sterkfontein OTU). PAUP 4.0 was used to construct cladograms and address hypotheses about relationships. In the analysis that treated the South African specimens as a single OTU, the position of that OTU was stable as a separate branch on the Homo clade between H. rudolfensis and [H. habilis+(H. erectus+H. sapiens)]. When SK 847 and Stw 53 were treated as separate OTUs, the majority of most parsimonious trees indicated that they were positioned in similar positions as the combined South African Homo OTU; that is, as separate branches between H. rudolfensis and [H. habilis+(H. erectus+H. sapiens)], with the Swartkrans OTU generally occupying a more derived position. The position of the Sterkfontein OTU was more stable than that of the Swartkrans OTU, which was found in several other positions among the minimum length trees. Running the analyses with only those characters preserved by SK 847 and Stw 53 resulted in similar topologies for minimum length trees, although the positions of Stw 53, SK 847, and H. habilis exchanged places in some trees. In no case was an exclusive sister relationship between either South African OTU and a particular species of Homo supported statistically. Both South African OTUs differ from H. habilis in the fewest number of cladistic characters.

    After the upsurge of domestic turmoil in Tunis last December, unrest spread rapidly through North Africa and the Middle East, having a profound effect on current international relations. It will continue to affect relations between the major powers and the international system as a whole for some time to come. The regional turmoil of North Africa and the Middle East is of particular interest to International Political Economy (IPE) studies. It seems to embody a geostrategic conflict between the US and the EU in contending for leadership in North Africa and the Middle East. It is also an expression of the competition for dominance of the global financial structure between the major powers during a period of transition in the international system. Lastly, it is a manifestation of America's struggle to maintain its global economic hegemony.

    Full Text Available Abstract Background In East Africa, foot-and-mouth disease virus serotype SAT 1 is responsible for occasional severe outbreaks in livestock and is known to be maintained within the buffalo populations. Little is known about the evolutionary forces underlying its epidemiology in the region. To enhance our appreciation of the epidemiological status of serotype SAT 1 virus in the region, we inferred its evolutionary and phylogeographic history by means of genealogy-based coalescent methods using 53 VP1 coding sequences covering a sampling period from 1948-2007. Results The VP1 coding sequence of 11 serotype SAT 1 FMD viruses from East Africa has been determined and compared with known sequences derived from other SAT 1 viruses from sub-Saharan Africa. Purifying (negative selection and low substitution rates characterized the SAT 1 virus isolates in East Africa. Two virus groups with probable independent introductions from southern Africa were identified from a maximum clade credibility tree. One group was exclusive to Uganda while the other was present within Kenya and Tanzania. Conclusions Our results provide a baseline characterization of the inter-regional spread of SAT 1 in sub-Saharan Africa and highlight the importance of a regional approach to trans-boundary animal disease control in order to monitor circulating strains and apply appropriate vaccines.

    Full Text Available The burden of non–communicable diseases is growing, particularly in developing countries. The greatest economic burden is due to dementia, the prevalence of which is rising with increasing longevity. In Africa, where the rate of increase of elderly persons is the fastest in the world, dementia is normally dismissed as a part of normal ageing. The lack of awareness means that many patients are suffering undiagnosed. This review aims to assess the information on the prevalence of dementia in Africa in order to estimate the current burden.

    There is a growing need for improved access to reliable water in Africa as population and food production increases. Currently approximately 300 million people do not have access to a secure source of safe drinking water. To meet these current and future demands, groundwater will need to be increasingly abstracted; groundwater is more reliable than surface water sources due to its relatively long response time to meteorological stresses and therefore is likely to be a more secure water resource in a more variable climate. Recent studies also quantified the volumes of groundwater potentially available which suggest that, if exploited, groundwater could help to meet the demand for fresh water. However, there is still considerable uncertainty as to how these resources may respond in the future due to changes in groundwater recharge and abstraction. Understanding and quantifying groundwater recharge is vital as it forms a primary indicator of the sustainability of underlying groundwater resources. Computational hydrological models provide a means to do this, but the complexity of recharge processes in Africa mean that these simulations are often highly uncertain. This study aims to evaluate our confidence in simulating groundwater recharge over Africa based on a sensitivity analysis using a distributed hydrological model developed by the British Geological Survey, ZOODRM. The model includes land surface, canopy, river, soil and groundwater components. Each component is able to exchange water and as such, forms a distributed water balance of Africa. The components have been parameterised using available spatial datasets of African vegetation, land-use, soil and hydrogeology while the remaining parameters have been estimated by calibrating the model to available river flow data. Continental-scale gridded precipitation and potential evapotranspiration datasets, based on remotely sensed and ground observations, have been used to force the model. Following calibration, the

  1. The inter-annual variability of Africa's ecosystem productivity: a multi-model analysis

    Full Text Available We are comparing spatially explicit process-model based estimates of the terrestrial carbon balance and its components over Africa and confront them with remote sensing based proxies of vegetation productivity and atmospheric inversions of land-atmosphere net carbon exchange. Particular emphasis is on characterizing the patterns of interannual variability of carbon fluxes and analyzing the factors and processes responsible for it. For this purpose simulations with the terrestrial biosphere models ORCHIDEE, LPJ-DGVM, LPJ-Guess and JULES have been performed using a standardized modeling protocol and a uniform set of corrected climate forcing data. While the models differ concerning the absolute magnitude of carbon fluxes, we find several robust patterns of interannual variability among the models. Models exhibit largest interannual variability in southern and eastern Africa, regions which are primarily covered by herbaceous vegetation. Interannual variability of the net carbon balance appears to be more strongly influenced by gross primary production than by ecosystem respiration. A principal component analysis indicates that moisture is the main driving factor of interannual gross primary production variability for those regions. On the contrary in a large part of the inner tropics radiation appears to be limiting in two models. These patterns are corroborated by remotely sensed vegetation properties from the SeaWiFS satellite sensor. Inverse atmospheric modeling estimates of surface carbon fluxes are less conclusive at this point, implying the need for a denser network of observation stations over Africa.

    There is re-emerging interest in community health workers (CHWs) as part of wider policies regarding task-shifting within human resources for health. This paper examines the history of CHW programmes established in South Africa in the later apartheid years (1970s-1994) - a time of innovative initiatives. After 1994, the new democratic government embraced primary healthcare (PHC), however CHW initiatives were not included in their health plan and most of these programmes subsequently collapsed. Since then a wide array of disease-focused CHW projects have emerged, particularly within HIV care. Thirteen oral history interviews and eight witness seminars were conducted in South Africa in April 2008 with founders and CHWs from these earlier programmes. These data were triangulated with written primary sources and analysed using thematic content analysis. The study suggests that 1970s-1990s CHW programmes were seen as innovative, responsive, comprehensive and empowering for staff and communities, a focus which respondents felt was lost within current programmes. The growth of these earlier projects was underpinned by the struggle against apartheid. Respondents felt that the more technical focus of current CHW programmes under-utilise a valuable human resource which previously had a much wider social and health impact. These prior experiences and lessons learned could usefully inform policy-making frameworks for CHWs in South Africa today.

    In December 2003, seventeen years after the first UK research assessment exercise, Italy started up its first-ever national research evaluation, with the aim to evaluate, using the peer review method, the excellence of the national research production. The evaluation involved 20 disciplinary areas, 102 research structures, 18,500 research products and 6,661 peer reviewers (1,465 from abroad); it had a direct cost of 3.55 millions Euros and a time length spanning over 18 months. The introduction of ratings based on ex post quality of output and not on ex ante respect for parameters and compliance is an important leap forward of the national research evaluation system toward meritocracy. From the bibliometric perspective, the national assessment offered the unprecedented opportunity to perform a large-scale comparison of peer review and bibliometric indicators for an important share of the Italian research production. The present investigation takes full advantage of this opportunity to test whether peer review...

    Full Text Available Introduction: Although hepatitis C virus (HCV screening is recommended for all HIV-infected patients initiating antiretroviral therapy, data on epidemiologic characteristics of HCV infection in resource-limited settings are scarce. Methods: We searched PubMed and EMBASE for studies assessing the prevalence of HCV infection among HIV-infected individuals in Africa and extracted data on laboratory methods used. Prevalence estimates from individual studies were combined for each country using random-effects meta-analysis. The importance of study design, population and setting as well as type of test (anti-HCV antibody tests and polymerase chain reactions was examined with meta-regression. Results: Three randomized controlled trials, 28 cohort studies and 121 cross-sectional analyses with 108,180 HIV-infected individuals from 35 countries were included. The majority of data came from outpatient populations (55%, followed by blood donors (15% and pregnant women (14%. Based on estimates from 159 study populations, anti-HCV positivity prevalence ranged between 3.3% (95% confidence interval (CI 1.8–4.7 in Southern Africa and 42.3% (95% CI 4.1–80.5 in North Africa. Study design, type of setting and age distribution did not influence this prevalence significantly. The prevalence of replicating HCV infection, estimated from data of 29 cohorts, was 2.0% (95% CI 1.5–2.6. Ten studies from nine countries reported the HCV genotype of 74 samples, 53% were genotype 1, 24% genotype 2, 14% genotype 4 and 9% genotypes 3, 5 or 6. Conclusions: The prevalence of anti-HCV antibodies is high in HIV-infected patients in Africa, but replicating HCV infection is rare and varies widely across countries.

    We performed a bibliometric analysis to evaluate the global scientific production on seamount biodiver-sity research from 1991 to 2014. This analysis was conducted based on the Science Citation Index Expanded data-base. The following important aspects were analyzed: publication performance, research emphasis, and research trends. USA published the highest number of papers in this field, and the National Institute of Water and Atmos-pheric Research, New Zealand, was analyzed to be the most productive institution. Analyses of author keywords suggest “new species” and “taxonomy” to be the two most frequently studied subject areas. Topics such as “hydro-thermal vent, ” “mitochondrial DNA, ” and “conservation” have become increasingly common. Furthermore, our findings suggest that domestic research in this area is still in its infancy and needs to be strengthened.%为了解海山生物多样性研究领域的研究现状和研究热点,本文采用文献计量学的方法对1991~2014年海山生物多样性相关的 SCI 论文产出进行了分析。结果表明,美国是该领域发文量最多的国家,新西兰水和大气国家研究所是发文量最多的机构。关键词分析的结果显示,海山生物多样性领域的研究热点主要集中在新物种发现和分类学,涉及“hydrothermal vent”(热液喷口)、“mitochondrial DNA”(线粒体DNA)及“conservation(保护)”等关键词的研究近几年逐渐增多。研究结果同时表明我国在该领域的研究较少,研究力度有待加强。

    1999-06-01

    Full Text Available A historiographic analysis of Levantine rock art studies from their origins to the present using a bibliometric study is presented. The research is based on a bibliographic data base integrated by 521 records (notes, reports, papers, chapters of books and monographs and 235 authors. Three periods (1907-1960, 1960-1980, 1980-1995 have been defined on the basis of the production, themes and characteristics of the authors. The institutionalization of Spanish archaeology, and the partiality and localism of current research are stressed. The huge activity of local scholars is remarkable in the first period. In the second one the number of authors and they monopolise a large part of the research. The foreign contribution disappears, and female researchers appear Finally, in the third period the percentage of publications increases and the descentralization of the study of Levantine rock art takes place. The independent authors as well as researchers assigned to regional administrations prevail over the academic researchers. The most relevant conclusion of this study is the persistence of iconography and simple description as the main aims of research on Levantine rock art during the entire century.

Hemos definido tres períodos (1907-1960, 1960-1980, 1980-1995 a partir de la producción, la temática y las características de autor. Hacemos hincapié en la institucionalización de la arqueología española, el personalismo y el actual localismo de la investigación. La primera etapa destaca por la gran actividad de eruditos locales, mientras que en la segunda el número de autores se reduce

    2015-06-01

    The quantitative evaluation of scientific research relies increasingly on bibliometric indicators of publications and citations. We present the issues raised by the simplistic use of these methods and recall the dangers of using poorly built indicators and technically defective rankings that do not measure the dimensions they are supposed to measure, for example the of publications, laboratories or universities. We show that francophone journals are particularly susceptible to suffer from the bad uses of too simplistic bibliometric rankings of scientific journals.
