Laser research in India: Scientometric study and model projections

An analysis of 785 papers, books and reports, in the field of laser, published from India during 1967–84, indicates that Indian output comprises almost 1% of the international output. The total output came from 77 academic and research institutions, out of which 10 institutions contributed almost 23%. Major portion of these publications appeared in foreign journals of repute, as reflected by their impact factors. Emphasis has been on theoretical aspects of laser research. The laser research performed in India appears to be a part of mainstream science as indicated by the pattern of publications and citations. The study also indicates that Indian scientists have few international collaboration in this field. A mathematical model for growth of literature output shows that though the rate of Indian literature output peaked at about the same time as that of the world output, Indian output may start getting marginalised by 1995. The model indicates that reasons for this lie in relatively less emphasis in India on experimental and applied aspects of laser research compared to international averages.     

Mapping of Indian computer science research output, 1999�C2008

It also analyses the characteristics of most productive institutions, authors and high-cited papers. The publications output and impact of India is also compared with China, South Korea, Taiwan and Brazil.     

Scientometric profile of Indian agricultural research as seen through Science Citation Index Expanded

Summary An analysis of 16891 publications published by Indian scientists during 1993-2002 and indexed by Science Citation Index Expanded (Web of Science) indicates that the publication output in the agricultural sciences is on the decline since 1998 onwards. 'Dairy and animal sciences' followed by 'veterinary sciences' constitute the largest component of the Indian agricultural research output. Agricultural universities and institutes under the aegis of Indian Council of Agricultural Research (ICAR) are the major producers of research output. Most of the papers have been published in domestic journals and in low normalized impact factor journals with a low rate of citation per paper. Most of the highly productive institutions are either agricultural universities or the institutes under the aegis of ICAR. Most of the prolific authors are from the highly productive institutions. However, only a few highly cited authors are from highly productive institutions.     

Mapping of dental science research in India: a scientometric analysis of India’s research output, 1999–2008

The study examines India’s performance based on its publication output in dental sciences during 1999–2008, based on several parameters, including the country annual average growth rate, global publication share & rank among 25 most productive countries of the world, national publication output and impact in terms of average citations per paper, international collaboration output and share and contribution of major collaborative partners, contribution and impact of select top 25 Indian institutions and select top 15 most productive authors, patterns of communication in national and international journals and characteristics of its 45 high cited papers. The study uses 10 years (1999–2008) publications data in dental sciences of India and other countries drawn from Scopus international multidisciplinary bibliographical database.     

Status of India in science and technology as reflected in its publication output in the Scopus international database, 1996–2006

This paper seeks to provide current indicators on Indian science and technology for measuring the country’s progress in research. The study uses for the purpose 11 years publications data on India and top 20 productive countries as drawn from the Scopus database for the period 1996 to 2006. The study examines country performance on several measures including country publication share in the world research output, country publication share in various subjects in the national context and in the global context, patterns of research communication in core Indian domestic and international journals, geographical distribution of publications, share of international collaborative papers at the national level as well as across subjects and characteristics of high productivity institutions, scientists and cited papers. The paper also compares the similarity of Indian research profile with top 20 productive countries. The findings of the study should be of special significance to the planners & policy-makers as they have implications for the long term S&T planning of the country.     

Scientometrics of institutional productivity of laser science and technology

An analysis of 4650 publications abstracted inJournal of Current Laser Abstracts (JCLA) during April 1990–March 1991 indicates that 50 institutions located in 14 countries contributed about 39% of the S&T output. Twenty two of these institutions were from the USA, four each from Japan and the former USSR. Academic and research institutions were mainly concentrating their research efforts either in theoretical or experimental laser research. However, the industrial houses pursued their research in applications of the lasers. Most of these institutions published their output in scientific journals, but a few institutions had large amounts of technical reports and patents to their credit. Most of the institutions resembled in their activity and attractivity profiles. The values of normalized impact per paper, publication effectivity index and proportion of high quality papers for 12 institutions were less than average.     

India’s contribution on antioxidants: a bibliometric analysis, 2001–10

The study examines India’s performance on antioxidants using several quantitative measures such as India’s global publication share, rank, growth rate and citation quality, its publication share in various sub-fields in terms of national share utilising last 10 year’s (2001–10) publications data obtained from the Scopus database. We have also determined Indian share with international collaborative papers at the national level as well as is major international collaborative partners, besides analysing the characteristics of its high productivity institutions, authors and high-cited papers, etc.     

Fish science research in China: How does it compare with fish research in India?

Fish and aquaculture research in the People's Republic of China over the six years 1994-1999 has been mapped using data from six databases– three abstracting services and three citation indexes. The results are compared with fish science research in India. During the six years China has published 2035 papers (roughly 4.5 –5% of the world output) and India 2454. More than 95% of China's papers are journal articles, compared to 82.8% of Indian papers. About 78% of China's journal paper output has appeared in 143 domestic journals compared to 70% from India in 113 Indian journals. Less than one-eighth of the journal articles published by Chinese researchers are published in journals indexed in SCI, compared to 30% of journal articles by Indian researchers. Less than a dozen papers from each of these countries have appeared in journals of impact factor greater than 3.0. Fish research institutes and fishery colleges are the major contributors of the Chinese research output in this area. In India academic institutions are the leading contributors (61%), followed by central government institutions (>25%). Qingdao, Wuhan, Beijing and Shanghai are the cities and Shandong, Hubei and Fujian are the provinces contributing a large number of papers. As we do not have addresses of all authors in most of the papers, we are unable to estimate the extent of international collaboration. Although China's research output and its citation impact are less than those of India, China's fish production and export earnings are far higher than those of India. Probably China is better at bridging the gap between knowhow (research) and do-how (technology and creation of employment and wealth). China is pretty strong in extension. This revised version was published online in June 2006 with corrections to the Cover Date.     

Scientometrics of laser research in India and China

An analysis of 1223 papers published by India (347papers) and China (876papers) at conferences and in journals during 1993 and 1997 in the field of laser S&T indicates that China"s output was twice to that of India. However, Activity Indices for both the countries in 1993 and 1997 were almost the same. Chinese scientists preferred to publish in domestic journals, while Indian scientists published in foreign journals. The number of papers by Indian scientists in SCI covered journals and journals with high-Normalized Impact Factors was more than for China, and, thus India was better connected to the mainstream science compared to China. The impact made by Indian papers was more than for Chinese papers, as reflected by normalized impact per paper, proportion of papers in high quality journals, and publication effective index. Indian papers also got more citations per paper than Chinese papers. Team research appears to be better in China than in India, as reflected by the number of mega-authored papers produced by the two countries. This revised version was published online in June 2006 with corrections to the Cover Date.     

Bibliometric analysis of complementary and alternative medicine research over three decades

This study applies bibliometric analysis to investigate the quantity and citation impact of scientific papers in the field of complementary and alternative medicine (CAM). The data are collected from 19 CAM journals in the Science Citation Index Expanded (SCI-E) database during 1980–2009, and 17,002 papers are identified for analysis. The study analyzes the document types, geographical and institutional distribution of the authorship, including international scientific collaboration. This study suggests that the major type of document is original article. The CAM papers are mostly published by North America, East Asia, and European countries, of which publications authored in East Asia are cited most. Country-wise, major contributors of CAM papers are from USA, People’s Republic of China, India, England and Germany. India has the highest CPP value, attracting high attentions in CAM community. This article also finds that international co-authorship in the CAM field has increased rapidly during this period. In addition, internationally collaborated publications generate higher citation impact than papers published by authors from single country. Finally, the research identifies productive institutions in CAM, and China Medical University located in Taiwan is the most productive organization.     

Research output in pheromone biology: a case study of India

Analyses the growth and development of pheromone biology research productivity in India in terms of publication output as reflected in Science Citation Index (SCI) for the period 1978–2008. It includes 330 publications from India, including 285 articles, 22 notes, 18 reviews, 4 letters and 1 conference paper, from 200 institutions. About 9.4 % of publications is contributed by Indian Institute of Technology, Kanpur followed by Bhabha Atomic Research Centre, Bombay (7.27 %). All the papers published by Indian researchers have appeared in journals with impact factors between 0.20 and 4.14. About 24.24 % of authors contributed single articles. The growth rate of publications varied from 0.30 to 9.09 % per year. The annual growth rate was highest in the year 2006 at 9.09 %. The study reveals that the output of pheromone biology research in India has gradually increased over the years.     

Renewable energy research 1995–2009: a case study of wind power research in EU, Spain, Germany and Denmark

The paper reports the developments and citation patterns over three time periods of research on Renewable Energy generation and Wind Power 1995–2011 in EU, Spain, Germany and Denmark. Analyses are based on Web of Science and incorporate journal articles as well as conference proceeding papers. Scientometric indicators include publication collaboration ratios, top-player distribution as well as citedness and correspondence analyses of citing publications, relative citation impact, distributions of top-cited as well as top-citing institutions and publication sources and cluster analysis of citing title terms to map knowledge export areas. Findings show an increase in citation impact for Renewable Energy and Wind Power research albeit hampered by scarcely cited conference papers. Although EU maintains its global top position in producing Renewable Energy and Wind Power research the developments of EU and German world shares as well as citation impact are negative during the most recent 7 year period. During the same time the citation impact of Spain and Denmark increase and place both nations among the top-ranking countries in Wind Power research. Spain is the only EU country that increases its world production share from 2000. China is currently ranked three after EU and USA in research output, however with a very low citation impact. Spain, Denmark and Germany each demonstrates distinct collaboration patterns and publication source and citation distribution profiles. More than half the citations to EU Wind Power research are EU-self citations. An expected intensified EU collaboration in the Wind Energy field does not come about. The most productive research institutions in Denmark and Spain are also the most cited ones.     

Use of citation per publication as an indicator to evaluate pentachlorophenol research

The objective of the study was to perform a bibliometric analysis of all pentachlorophenolrelated publications in the Science Citation Index (SCI). Analyzed parameters included document type, language of publication, page count, publication output, authorship, keywords plus, publication pattern, citation and country of publication. The US produced 29% of the total single country publications where the seven major industrial countries accounted for the majority of the total production (66%). An indicator citation per publication was successfully applied in this study to evaluate the impact of number of authors, countries, and journals. The mean value of citation per publication of collaborative papers was higher than that of single country publications. In addition analysis of keywords plus in different period was applied to indicate a research trend.     

S&T publications output of Nepal: a quantitative analysis, 2001–10

This study analyses the research output of Nepal in S&T during 2001–10 on several parameters including its growth and country publications share in the world’s research output, country publications share in various subjects in the national and global context, pattern of research communication in core domestic and international journals, geographical distribution of publications, share of international collaborative publications at the national level as well as across subjects and characteristics of high productivity institutions, authors and cited papers. The Scopus Citation Database has been used to retrieve the publication data for 10 years.     

Research and patenting in Indian universities and technical institutes: An exploratory study

This study uses data on publication, and patents, of 347 universities and technical institutes of India from 1970 to 2010, to understand their current research status. We find that though the total number of patents and publications has been increasing gradually, the contribution of Indian academic institutions in patenting is still low and needs to be incentivized.     

Bibliometric analysis of biological invasions research during the period of 1991 to 2007

The objective of this study is to conduct a bibliometric analysis of all biological invasions-related publications in the Science Citation Index (SCI) from 1991 to 2007. The indicator citation per publication (CPP) was used to evaluate the impact of articles, journals, and institutions. In the 3323 articles published in 521 journals, 7261 authors from 1905 institutions of 100 countries participated. As the most productive country of biological invasions research, the US will benefit from more collaboration between institutions, countries, and continents. In addition, analysis of keywords was applied to reveal research trends.     

Scientometrics of laser research literature as viewed through the Journal of Current Laser Abstracts

An analysis of 4650 publications abstracted inJournal of Current Laser Abstracts Vol. 27 (April 1990-March 1991) indicates that 14 countries contributed about 94% of the research output with USA toping the list followed by Japan and the erstwhile USSR. Technical reports and patents, besides articles in scientific journals constitute an important source of information on laser science and technology. “Spectroscopy of laser output” is the sub-speciality which has received maximum emphasis. USA has paid almost equal emphasis for theoretical, experimental and applications of laser research, while such pattern is not applicable for other countries. For USSR, China, and India, the impact of research did not commensurate with the publication effort.     

Scientometrics of computer science research in India and China

Summary An analysis of 2058 papers published by Chinese authors and 2678 papers published by Indian authors in the field of computer science during 1971-2000 indicates that India's output is significantly higher than the Chinese output. However, China is catching up fast. Chinese researchers prefer to publish their research results in domestic journals, while Indian researchers prefer to publish their research results in journals published in the advanced countries of the West. Also the share of papers in journals covered by SCI for India was higher than from China. However, no significant difference has been observed in the impact of the research output of the two countries as seen by different impact indicators. Team research is more common in India as compared to China.     

Science in Scandinavia: A Bibliometric Approach

The development of publication activity and citation impact in Scandinavian countries is studied for the 1980–1997 period. Besides the analysis of trends in publication and citation patterns and of national publication profiles, an attempt is made to find statistical evidences of the relation between international co-authorship and both research profile and citation impact in the Nordic countries. A coherent Scandinavian cluster has been found, and the Nordic countries have strong co-authorship links with highly developed countries in West Europe and North America. It was found that international co-authorship, in general, results in publications with higher citation rates than purely domestic papers. International collaboration has, however, not the same influence on publication profiles and citation impact of each analysed countries.     

Scientometrics of the international journal Scientometrics

An analysis of 1317 papers published in first fifty volumes during 1978 to 2001 of the international journal Scientometrics indicates the heterogeneity of the field with emphasis on scientometric assessment. The study indicates that the US share of papers is constantly on the decline while that of the Netherlands, India, France and Japan is on the rise. The research output is highly scattered as indicated by the average number of papers per institution. The scientometric output is dominated by the single authored papers, however, multi-authored papers are gaining momentum. Similar pattern has been observed for domestic and international collaboration.
