The evolution of the sleep science literature over 30 years: A bibliometric analysis

During the 1974–2004 period, the sleep literature had quadrupled (2384 publications in 1974, and 9721 in 2004) while overall scientific productivity had only doubled. The set of the seven most productive countries (USA, Japan, United Kingdom, Germany, France, Canada and Italy) in sleep research, and the geographical region distribution remained stable over the three decades. On the other hand several indicators appeared in the sleep research literature during the 1990s: the increasing productivity of sleep researchers; the growing number of countries publishing on sleep; the continuous creation of sleep-focused journals; the scattering of sleep publication among increasingly more scientific journals; the turnover among the leading journals; and the emergence of new entities such as China, Turkey, and the European Union.     

Global knowledge management research: A bibliometric analysis

The present study characterizes the dynamic publication activity of global knowledge management (KM) by data collected through a search restricted to articles in ISI Web of Science.A total of 2727 unique authors had contributed 1407 publications since 1975. The overwhelming majority (2349 or 86%) of them wrote one publication. The productive authors, their contribution and authorship position are listed to indicate their productivity and degree of involvement in their research publications. The sum of research output of the first or responsible authors from USA, UK and Germany reaches 57% of the total productivity. The distribution of articles is rather widespread - they published in 462 titles of serials, spanning 110 Journal Citation Reports subject categories. The higher quality journals make publication of findings more visible. A Pearson's correlation coefficient is statistically found to be significant between citation frequency of article and impact factor of journal, instead of authorship pattern. The results also indicate that R&D expenditures were actually not proportional to research productivity or citation counts. As the subject highly interacts with other disciplines, the field of KM has not yet developed its own body of literature. KM might have been evolving an interdisciplinary theory that is developing at the boundaries of scientific disciplines. This revised version was published online in June 2006 with corrections to the Cover Date.     

A small country in a world of big science a preliminary bibliometric study of science in Singapore

An analysis of 258 papers published from Singapore and covered inScience Citation Index (SCI) 1979 and 1980 indicates that (1) much of R&D in Singapore pertains to medical research, (2) almost all the papers are published in English language periodicals published from the western world, (3) nearly two-thirds of Singapore's publication output is accounted for by the University of Singapore, and (4) by and large papers from Singapore are rarely cited, even if many of them have appeared in journals having impact factor greater than one.     

Canadian research activity in aquaculture: A bibliometric analysis

Analysis of the Canadian publications in the field of aquaculture reveals that Canada is one of the word's major contributors in this area. This confirms that Canada's expertise in science and technology often finds its stimulus in its resource-based industries. Several bibliometric indicators were used to enlighten the peculiar features of the Canadian research system. These include the channels of communication used by scientists, the authorship pattern, the level of collaboration, the identification of the institutions in which the research is performed and the uneven research effort distribution inside the country. The relevance of such quantitative measures for science policy-making is emphasized. The present study shows how bibliometric analysis, by describing the actual strengths and weaknesses of Canadian research and identifying the agents of this research activity, might foster a better understanding of the Canadian research enterprise as a whole.     

The global institutionalization of nanotechnology research: A bibliometric approach to the assessment of science policy

Based on bibliometric methods, this paper describes the global institutionalization of nanotechnology research from the mid-1980s to 2006. Owing to an extremely strong dynamics, the institutionalization of nanotechnology is likely to surpass those of major disciplines in only a few years. A breakdown of the relative institutionalizations strengths by the main geographical regions, countries, research sectors, disciplines, and institutional types provides a very diverse picture over the time period because of different national science policies. The results allow a critical assessment of the different science policies based on the relative institutionalizations strengths as well as the conclusion that the institutionalization process has run out of control of individual governments who once induced the development.

International contribution to library and information science in Poland: A bibliometric analysis

This article reports findings from the study of the international contribution to the system of library and information science communication in Poland in the years 2003–2005. The sample consists of articles published both in selected journals and collective works. Two important dimensions determining the internationalization of local scholarly communication are considered: direct contribution (foreign authors’ articles and papers and their translations published in Poland) and indirect contribution (citedness of foreign authors’ documents in articles and papers published in Poland). Bibliographic data about the geographical distribution and affiliation of foreign authors are gathered and analyzed. Furthermore, the findings of citation analysis are presented to determine the percentage share of citations received by foreign documents as well as to find out what is the structure of such citations regarding the language and form, which thematic areas are most replete with such citations and which foreign journals are most cited in Poland.     

Strength and weakness of national science systems: A bibliometric analysis through cooperation patterns

In this study we have focused on long term developments of various types of scientific publishing, and the field-normalized impact generated by these various types. The types of scientific output distinguished are output resulting from international cooperation, national cooperation, and single address publications, in which no apparent cooperation is found. A fourth type is distinguished by focusing on first authorship, within the international cooperation output. Changes in especially the share of a country’s output from first-authored international cooperation and the share of single address publications can be regarded as indicators of strength and/or weakness of a science system.     

Open data and open code for big science of science studies

Historically, science of science (Sci2) studies have been performed by single investigators or small teams. As the size and complexity of data sets and analyses scales up, a “Big Science” approach (Price, Little science, big science, 1963) is required that exploits the expertise and resources of interdisciplinary teams spanning academic, government, and industry boundaries. Big Sci2 studies utilize “big data”, i.e., large, complex, diverse, longitudinal, and/or distributed datasets that might be owned by different stakeholders. They apply a systems science approach to uncover hidden patterns, bursts of activity, correlations, and laws. They make available open data and open code in support of replication of results, iterative refinement of approaches and tools, and education. This paper introduces a database-tool infrastructure that was designed to support big Sci2 studies. The open access Scholarly Database (http://sdb.cns.iu.edu) provides easy access to 26 million paper, patent, grant, and clinical trial records. The open source Sci2 tool (http://sci2.cns.iu.edu) supports temporal, geospatial, topical, and network studies. The scalability of the infrastructure is examined. Results show that temporal analyses scale linearly with the number of records and file size, while the geospatial algorithm showed quadratic growth. The number of edges rather than nodes determined performance for network based algorithms.

A bibliometric and citation analysis of stroke-related research in Taiwan

As the population ages in Taiwan, stroke research has received greater attention in recent years. Strokes have significant impacts on the health and well-being of the elderly. To formulate future research policy, information on stroke publications should be collected. In this research, we studied stroke-related research articles published by Taiwan researchers which were indexed in the Science Citation Index from 1991 to 2005. We found that the quantity of publications has increased at a quicker pace than the worldwide trend. Over the years, there has been an increase in international collaboration, mainly with researchers in the U.S. Article visibility, measured as the frequency of being cited, also increased during the period. It appears that stroke research in Taiwan has become more globally connected and has also improved in quality. The publication output was concentrated in a few institutes, but there was a wide variation among these institutes in the ability to independently conduct research. A wide array of keywords indicated a probable lack of continuity in research. Nevertheless, there was an inverse relationship between stroke mortality and number of published articles in Taiwan. To improve the quality and efficiency of stroke research, continuity in research focuses needs to be maintained, and thus funding should be allocated on a long-term basis to institutes with a proven record of success.

A bibliometric analysis of research related to ocean circulation

This study is a bibliometric analysis on ocean circulation-related research for the period 1991–2005. Selected documents included “ocean circulation, sea circulation, seas circulation, marine circulation, and circulation ocean” as a part of the title, abstract or keywords. Analyzed parameters included the document type, the article output, the article distribution in journals, the publication activity of countries, and institutes and the authorship. An indicator, citation per publication (CPP) was applied to evaluate the scientific impact of a publication. The relationship between cumulative articles and the year was modeled. Three dominant categories were picked out, and their output increase was modeled. The USA was found to be leading the research with 47% share of total articles, with a CPP up to 5.9. Woods Hole Oceanography Institute in the USA was the most productive institute with a CPP of 6.8. In the citation analysis, a 5th year citation mode was found. A paper life model was applied to compare the cumulative citations increasing rates of different years.     

Significant Mexican research in the health sciences: A bibliometric analysis

In the 1970s Mexico started to consolidate its S&T system by training human resources and actively preventing brain drain, mainly by motivating researchers through economic incentives. Considering Bradford"s Law, an analysis of significant Mexican research in the health sciences, i.e., papers published in journals with a high-impact factor which grant a degree of credibility and importance was carried out. Significant papers produced in Mexico show a measure of the country"s productivity, and these papers" citations measure the country"s international impact.     

Smart bibliometrics: an integrated method of science mapping and bibliometric analysis

Bibliometric techniques and science mapping are widely employed in the research environment to provide an overview of the state-of-the-art of scientific knowledge on a given topic. These techniques are essential to assist the researcher's work by guiding the compilation of the bibliography to support the theory discussion. To this objective, the Smart Bibliometrics was developed to facilitate bibliometric analysis and selection of theoretical references, embodied by a system that brings intelligence, dynamism, and agility to the scientific writing process. The innovation of this methodology is the fusion of two relevant criteria applied during the bibliometric analysis process: the application of a representative metric of classification of scientific papers and dynamic visuals strategically developed. The methodology differs for providing the user with dynamic navigation and interaction experience with the data collected, innovating the approach to reaching insights within the universe of discussions of the scientific community. In addition, as an innovation factor, the method is presented in a scalable Business Intelligence (BI) system that features blunt visuals, extensive analysis repertoire, intuitive navigation, and automated updating. The development was carried out in a cutting-edge technological platform to attend information and sharing intents by employing cloud computing resources, another feature that enables interaction among researcher groups also from different institutions. Additionally, it is not necessary to install any software. The output will be available for consultation, at any time and place, just by using one device with an internet connection.

     

Facebook in educational research: a bibliometric analysis

Facebook has become the object of research in different areas. The present study presents a bibliometric analysis of the scientific literature related to the use of this social network in educational research. To this end, bibliometric techniques were applied in the analysis of scientific articles indexed at the Web of Science Core Collection, from Thomson Reuters, and linked to the research areas of Education/Educational Research. This resulted in the identification of, among others, developments in scientific production, the most important journals that publish papers on the topic, the main authors and the main articles published in the area. The results indicate the growth of scientific production in the area from 2008 onwards, pointing to Computers and Education as the most relevant journal by number of publications (22) and impact factor and indicate that authors from the United States, Australia, Taiwan, United Kingdom and South Africa stand out in the construction of knowledge on educational research applying Facebook. Moreover, the ego-network of the Educational Research area shows that this area coexists with other areas of knowledge in the use of social networking, such as Computer Science, Linguistics and Health Sciences, indicating an interdisciplinary and transversal nature in different areas of research.
