The examination of three samples of geological scientific publications: (A) 9 journals from Western Europe and USA; (B) 10 up-to-date review books, and (C) 3 sections of Volume 127 (1990–1991) of theZoological Record, shows that the statement that English is now the lingua franca in geological sciences is only in part true, but reflects a desire by many people in the scientific community, a desire which may not yet have been fulfilled  相似文献

We have studied the citation rates and characteristics of 572 Turkish physics publications that appeared in the source journals listed in theScience Citation Index (SCI) for the period 1982–1990 to drive the following results: The papers appeared in a set of 94 journals, and 68% of the total output went to 21 of these; half of which are journals of high impact. On the average, papers from Turkey that appeared in the American and European journals are cited at rates higher than the corresponding average papers. There has been a substantial shift of Turkish papers from European journals to American journals over the last few years. These changes are an example of the process by which science in a less developed country becomes integrated into the word scientific community.  相似文献

This paper presents a bibliometric analysis of articles from the Republic of Serbia in the period 2006–2012 that are indexed in the Thomson Reuters SCI-EXPANDED database. The Republic of Serbia is a small country in Europe with about seven million citizens that became an independent country in 2006. Since 2006, Serbian science has achieved some recognition. Analysis included 14,293 articles with authors all from Serbia. Distribution of published articles in the Web of Science categories, journals, scientific-research institutions and researchers were analysed. Most cited independent research articles from Serbia were also analysed. The Y-index indicator for rating the productivity of researchers and institutions was used. This indicator takes into account the contribution of the researcher to the published results. The results showed that the productivity of articles from Serbia is significant compared to neighbouring Serbian countries, taking into account the number of researchers in these countries, their GDPs and the percentages of GDPs spent on research.  相似文献

A top journal is defined as a journal which is within the first 10% of journals ranked by impact factor in the SCI list, within a particular scientific subfield, for the year considered. Journals which were for 11 or more years within the first 10% were considered top journals during the whole period even though they were not within the first 10%, in some of the years covered by this study.In the period from 1980 to 2000, the Croatian scientists affiliated with research institutions within the Republic of Croatia, published a total of 13,021 papers in journals covered by the Science Citation Index (SCI). Out of these papers, only 2,720 were published in top journals. This amounts to 20.9% of the total, and this is below the world average of 29.5% for the same scientific subfields. Out of the above 2,720 publications, 1,250 (46.0%) were published in international collaboration, and 335 (12.3%) papers were Meeting Abstracts. The Croatian scientists were most productive in the main scientific fields: Physics (875 papers; 32.2%), Medicine (786 papers; 28.9%), and Chemistry (580 papers; 21.3%). All others fields, taken together, comprised 17.6% of the total scientific output. Of the 786 medical papers, 290 were Meeting Abstracts, or 36.9% of the total output in the field of Medicine, and medical Meeting Abstracts represent 86.6% of the total number of abstracts (335). Articles (2,060) represent 75.7% of the total Croatian scientific output in top journals. This revised version was published online in June 2006 with corrections to the Cover Date.  相似文献

Conference proceedings are one of the key communication channels in computer science. This paper aims to analyze the Chinese outputs in the context of conference papers in computer science through an exploration of the conference proceedings series book-Lecture Notes in Computer Science (LNCS) in the period of 1997–2005. Results indicate that: 1. The number of Chinese papers in LNCS keeps growing in the studied period; the share of Chinese papers in LNCS in recent years is much higher than that of Chinese SCI papers in the world; In sharp contrast with remarkable growth of the share of Chinese papers in LNCS, the share of SCI articles in top journals of computer science published by the scientists of mainland China is negligible during the same period. 2. Chinese researchers are more likely to collaborate with domestic fellows; 3. In spite of the increasing amounts of Chinese papers in LNCS, they receive only a few citations; 4. The articles are strikingly more cited by authors themselves and international authors’ citations are more than Chinese authors’ non-self-citations in the first three years after publication; 5. Based on the new indicator Impact Index (II) the authors proposed, the relative impact of Chinese articles in LNCS is increasing although the average impact of Chinese papers in LNCS is obviously less than that of the publications in LNCS in each year during the studied period.  相似文献

A bibliometric analysis was conducted to evaluate the global scientific output of proteomics research in the Science Citation Index Expanded from 1995 to 2010. The document types, languages, journals, categories, countries, and institutions were analyzed to obtain publication patterns. Research focuses and trends were revealed by a word cluster method related to author keywords, title, abstract, and KeyWords Plus. Bradford’s Law and the correlation between keywords and institutions were identified to look deeper into the nature works. Proteomics and Journal of Proteome Research published the most articles in proteomics research. The researchers focused on the categories of biochemical research methods, and biochemistry and molecular biology. The USA and Harvard University were the most productive country and institution, respectively, while China was the fastest-growing country due to the support by Chinese government. The distribution of author keywords provided the important clues of hot issues. Results showed that mass spectrometry and two-dimensional gel electrophoresis had been the most frequently used research methods in the past 16 years; and cancer proteomics had a strong potential in the near future. Furthermore, biologists contributed significantly to proteomics research, and were more likely to co-operate with medical scientists.  相似文献

Summary This paper attempts to highlight quantitatively the growth and development of world literature on thorium in terms of publication output as per Science Citation Index (1982-2004). During 1982-2004 a total of 3987 papers were published by the scientists in the field 'thorium'. The average number of publications published per year were 173. The highest number of papers 249 were published in 2001. The spurt in the literature output was reported during 1991-2004.There were 94 countries involved in the research in this field. USA is the top producing country with 1000 authorships (21.11%) followed by India with 498 authorships (10.51%). Authorship and collaboration trend was towards multi-authored papers. Intensive collaboration was found during 1990-2004.One paper 'Nuclear Instruments and Methods in Physics Research - A 406 (3) (1998) 411-426' had 64 collaborators. There were 586 international collaborative papers. Bilateral collaboration accounted for 80.55 percent of total collaborative papers. Bhabha Atomic Research Centre (India) topped the list with 153 authorships followed by Los Alamos National Laboratory (USA) with 105 authorships.The most preferred journals by the scientists were: Journal of Radioanalytical Nuclear Chemistry with 181 papers, Radiochimica Acta with 139 papers, Journal of Radioanalytical Nuclear Chemistry -Articles with 127 papers, Geochimica Cosmochimica Acta with 96 papers, Health Physics with 91 papers, Applied Radiation and Isotopes with 88 papers, Journal of Alloys and Compounds with 65 papers, Earth and Planetary Science letters with 59 papers and Chemical Geology, Indian Journal of Chemistry -A, Radiation Protection Dosimetry with 55 papers each. English was the most predominant language used by the scientists for communication. The high frequency keywords were: Thorium (500), Uranium (284), Separation (94), Thorium Isotopes (90), Thorium (IV) (86), Seawater (73), Solvent Extraction (70), and Rare Earth Elements (68).  相似文献

Citation structure of an emerging research area on the verge of application   总被引:1,自引:0,他引:1  
A case study of an emerging research area is presented dealing with the creation of organic thin film transistors, a subtopic within the general area called “plastic electronics.” The purpose of this case study is to determine the structural properties of the citation network that may be characteristic of the emergence, development, and application or demise of a research area. Research on organic thin film transistors is highly interdisciplinary, involving journals and research groups from physics, chemistry, materials science, and engineering. There is a clear path to industrial applications if certain technical problems can be overcome. Despite the applied nature and potential for patentable inventions, scholarly publications from both academia and industry have continued at a rapid pace through 2007. The question is whether the bibliometric indicators point to a decline in this area due to imminent commercialization or to insurmountable technical problems with these materials.  相似文献

Indicators based on non-patent references (NPRs) are increasingly being used for measuring and assessing science–technology interactions. But NPRs in patent documents contain noise, as not all of them can be considered ‘scientific’. In this article, we introduce the results of a machine-learning algorithm that allows identifying scientific references in an automated manner. Using the obtained results, we analyze indicators based on NPRs, with a focus on the difference between NPR- and scientific non-patent references-based indicators. Differences between both indicators are significant and dependent on the considered patent system, the applicant country and the technological domain. These results signal the relevancy of delineating scientific references when using NPRs to assess the occurrence and impact of science–technology interactions.  相似文献

The paper analyses the output of the publication data of an Indian laboratory in the field of physics inSCI and nonSCI covered Indian and foreign journals, processes developed and Indian patents filed during the period 1965–82 to find out the pattern of productivity. Looks at the journals wherein the laboratory scientists publish. Also points out the sub-areas of physics in which the laboratory scientists have published maximum papers and also mentions about the pattern of scientific co-authorship in the research work. Correlation coefficients between input variable (manpower and budget) with output variables (number of papers published, processes developed and Indian patents accepted) have been calculated.  相似文献

Citation relationships are commonly described with citation network or citation graph, but in this article, the author introduced the notion of citation genetic genealogy and apply it in citation analysis. A citing document usually only uses pieces of its cited document, so the author of this article defined these valuable pieces of a scientific document, which carry the information that have been used by its citing documents as its document genes. Besides, with the definition of symbolic information of a scientific document, the conclusion that a citing document inherited the document genes from its references can be drawn. Based on these understandings, citation genetic genealogy is constructed to describe citation relationships. With citation genetic genealogy, it is easy to map the citation relationships, like bibliographic coupling and co-citation, with familiar family relationships and illustrate the inheritance relationships in scientific literatures. Also, citation genetic genealogy may provide an interface between the citation analysis of a document set and the content analysis for each individual document inside this document set.  相似文献

The long-term influence and contribution of research can be evaluated relatively reliably by bibliometric citation analysis. Previously, productivity of nations has been estimated by using either the number of published articles or journal impact factors and/or citation data. These studies show certain trends, but detailed analysis is not possible due to the assumption that all articles in a journal were equally cited. Here we describe the first comprehensive, longterm, nationwide analysis of scientific performance. We studied the lifetime research output of 748 Finnish principal investigators in biomedicine during the years 1966–2000, analysed national trends, and made a comparison with international research production. Our results indicate that analyses of the scientific contribution of persons, disciplines, or nations should be based on actual publication and citation counts rather than on derived information like impact factors. 51% of the principal investigators have published altogether 75% of the articles; however, the whole scientific community has contributed to the growth of biomedical research in Finland since the Second World War.  相似文献
