A Bibliometric Study of Scientific Research on Second-Generation Antipsychotic Drugs in Hong Kong
Clinical & Experimental Pharmacology, 2015
Background: We did a bibliometric study on the scientific publications on second-generation antipsychotic drugs (SGA) in Hong Kong. Methods: With the EMBASE and MEDLINE databases, we chose those English articles from Hong Kong. We used bibliometric indicators of Price's law for the increase of scientific literature, and of Bradford's law for dispersion of papers. We also calculated the participation index of the different countries. Then, we correlated those bibliometric information with some social and health data (such as total per capita expenditure on health and gross domestic expenditure on research and development) of Hong Kong. Results: Forty-four original papers were published between 1993 and 2011. Our results indicated non-fulfilment of Price's law (correlation coefficient r=0.5597 after exponential adjustment vs. r=0.6725 after linear adjustment). Those most widely studied SGA were clozapine (18 papers), risperidone (11 papers), and olanzapine (4 papers). Division into Bradford zones yielded a nucleus occupied by Journal of Clinical Psychopharmacology (4 articles) and Australian and New Zealand Journal of Psychiatry (4 articles). A total of 30 different journals were published. Conclusion: The SGA publications in Hong Kong are still too few to confirm an exponential growth of scientific papers.
The extreme upper tail of Japan's citation distribution reveals its research success
2022
A number of indications, such as the number of Nobel Prize winners, show Japan to be a scientifically advanced country. However, standard bibliometric indicators place Japan as a scientifically developing country. The present study is based on the conjecture that scientific publications from Japan belong to two different populations: one originates from studies that advance science and includes highly cited papers, while the other is formed by lowly cited papers with almost zero probability of being highly cited. Although these two categories of papers cannot be easily identified and separated, the scientific level of Japan and the hypothesis that would explain its poor bibliometric evaluations can be tested by studying the extreme upper tail of the citation distribution of all scientific articles. In contrast to standard bibliometric indicators, which are calculated from the total number of papers or from sets of papers in which the two categories of papers are mixed, in the extrem...
Trends in Scientific Literature on Atypical Antipsychotics in South Korea: A Bibliometric Study
Psychiatry Investigation, 2013
ObjectiveaaWe have carried out a bibliometric study on the scientific publications in relation to atypical or second-generation antipsychotic drugs (SGAs) in South Korea. MethodsaaWith the EMBASE and MEDLINE databases, we selected those publications made in South Korea whose title included the descriptors atypic* (atypical*) antipsychotic*, second-generation antipsychotic*, clozapine, risperidone, olanzapine, ziprasidone, quetiapine, sertindole, aripiprazole, paliperidone, amisulpride, zotepine, asenapine, iloperidone, lurasidone, perospirone and blonanserin. We applied some bibliometric indicators of paper production and dispersion with Price's law and Bradford's law, respectively. We also calculated the participation index (PI) of the different countries, and correlated the bibliometric data with some social and health data from Korea (such as total per capita expenditure on health and gross domestic expenditure on research and development). ResultsaaWe collected 326 original papers published between 1993 and 2011. Our results state fulfilment of fulfilled Price's law, with scientific production on SGAs showing exponential growth (correlation coefficient r=0.8978, as against an r=0.8149 after linear adjustment). The most widely studied drugs were risperidone (91 papers), aripiprazole (77), olanzapine (53), and clozapine (43). Division into Bradford zones yielded a nucleus occupied by the Progress in Neuro-Psychopharmacology and Biological Psychiatry (36 articles). A total of 86 different journals were published, with 4 of the first 10 used journals having an impact factor being greater than 4. ConclusionaaThe publications on SGAs in South Korea have undergone exponential growth over the studied period, without evidence of reaching a saturation point.
Molecules & Medicinal Chemistry, 2016
Background: We carried out a bibliometric study on the scientific publications on atypical antipsychotic drugs (AADs) from India. Methods: Using the EMBASE and MEDLINE databases, we performed the selection of documents produced in India. We applied bibliometric indicators of production and dispersion, namely Price's law on the increase of scientific literature and Bradford's law, respectively. We also calculated the participation index (PI) of different countries. The bibliometric data have also been correlated with relevant social and health data from India (including total per capita expenditure on health and gross domestic expenditure on research and development). Results: In this study, we identified 639 original documents published between 1998 and 2013 from India. Our results indicated fulfilment of Price's law (correlation coefficient r = 0.9619 after exponential adjustment vs. r = 0.9382 after linear adjustment). The most widely studied AADs were olanzapine (173 documents), clozapine (117), risperidone (100) and quetiapine (65). Publications appeared in 221 different journals, with only 4 of the top 10 journals having an impact factor greater than 2. Division into Bradford zones yielded a nucleus occupied by the Indian Journal of Psychiatry (53 articles). It is remarkable that the 27.38% of the production is devoted to "medical/pharmaceutical chemistry" field. India has the largest ratio PI AAD / PI Psychiatry and Neurology in the world's 12 most productive countries in biomedicine and health sciences. Conclusions: The publications on AADs in India have undergone exponential growth over the studied period, without evidence of reaching a saturation point.
Japan's share of research output in basic medical science
The Keio Journal of Medicine, 2004
Objective: To investigate the degree of Japan's contribution to the research in basic biomedical science in the last decade. Methods: Articles published during 1991-2000 in highly reputed basic biomedical science journals (10 journals from each of the 16 categories related to basic biomedical science) were accessed through Medline database. The number of articles having affiliation with a Japanese institution was then determined using appropriate search strategies. Results: In total 312,748 articles were published in the selected journals and Japan's share was 20,665 articles (6.6% of total) with an upward trend over time (p F 0.01). Japan's share was higher in the journals, which publish mostly original articles (6.9%) than that in the journals, which publish only review articles (2.6%). The former group showed an upward trend (p F 0.01) over time (1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000) while the latter did not (p F 0.08). Among the 16 categories, Japan had significantly positive trend in 7 categories while others remained unchanged. Conclusions: Japan's share of original articles for basic medical science has increased in the last decade. On the other hand, its share of review articles was low and has remained stagnant in the same period. (Keio J Med 53 (3): 172-177, September 2004)
In this study, we conducted quantitative analysis of 1706 scholarly literature published in Journal of Documentation during the period of 1970 to 2019 (fifty years) using a series of scientometric indicators. Annual scientific production, most local cited sources, the ranking of authors; profiles, contributions, correlation, collaboration and authorship pattern, most contributed countries, most cited articles, frequently used search terms/keywords, and the legend of historiographic mapping were analysed in detail to measure the impact of the source. Design/methodology/approach We used the Scopus database for retrieving the desired sample data. In total, 1,706 numbers of publications records were considered for the literature analysis considering their relevancy. Biblioshiny data visualization tool is used to create the various maps. Findings The present study found that annual scientific production and average citations constantly have had an uptrend. The journal's had tremendous impact with an h-index of 80, with a g-index of 148, total citations of 37,161 within the studied period. Although Bawden D contributed the highest number of research papers (n=78), the work published by Hjørland B received the highest citations. Lotka's Law reveals that about 75.04% of the authors (1319 authors) have one publication, and approximately 12.73% of the authors (225 authors) have two publications. The United Kingdom was the dominant country in terms of number of papers and citation count whereas University of Sheffield topped with 128 publications. The thematic map consists of eleven clusters and 'information retrieval' found to be the largest cluster comprehending 56 subthemes occurring 995 times. Co-citation network identified four clusters with revealing Wilson TD as the most cited authors. The study also indicates the most collaborative authors are from the United Kingdom. Research limitations/implications The study exclusively deals with 1732 published research literature indexed in the Scopus database covering a span of fifty years (from 1970 to 2019). Thus, documents which are not covered in Scopus are excluded from the purview of research. This study is significant in order to measure the impact of Journal of Documentation and useful to identify valuable research patterns from publications and of developments in the field of Information Science.
