Contribution and Performance of Indian Psychiatrists and a Pan-Indian Psychiatry Journal to Mental Health Literature during 2010-14

Introduction: The quality and quantity of manuscript contribution by Indian Psychiatrist and those by Indian Journal of Psychiatry (IJP) has not been assessed till date. Such a data would be helpful for the policymakers and all stakeholders to plan the future outlook of publishing in and by Psychiatrists. Material and Methods: Using previously described method, contribution of Indian Psychiatrists as well as that of IJP was collected from various resources. Also, such details were collected by hand from PubMed, Journal website and cross-checked with Google Page Ranking system via a specialized software. Results: Indian psychiatrists published 350 articles in 2010 that arose to 506 in 2014. Among the articles published in 2007-2009, only 75.14% were cited within three years while for the period, 2011-13, only 20.36% were cited. In the same time frame, manuscript published in IJP garnered 29.07% and 39.76%. Discussion: IJP is increasingly getting cited surpassing the other journals and nearly 2.5 times of the general medical field. Besides citation, the other quality parameters of IJP are being discussed. Increasing the quality of Indian psychiatrist research output will require a structured and planned program. The manuscript would aid to chalk future policy of research promotion among Indian Psychiatrists.

Social media research: A scientometric assessment of world publications output during 2001–2014

The paper examines world publications output on social media research (46354) published during 2001–2014. The publications data, sourced from Scopus database, averaged annual 14.61% growth. The paper profiles top 25 most productive organizations that accounted for 12.46% world share, and top 25 most productive authors that accounted for 2.34% world share on indicators such as average productivity, citations per paper, h-index, and share of international collaborative publications during 2001–2014. The distribution of world output by country of publication is highly skewed. The top 15 most productive countries account for bulk of the world output (82.40%). The USA has emerged as the world leader both in its world share and citations impact of social media research output. Blogs, among social media sites, accounted for the largest publication share 27.45%, followed by Facebook (16.75%), Twitter (15.86%), Wikipedia (10.58%), YouTube (7.24%), Flickr (3.94%), MySpace (1.73%), LinkedIn (1.21%), etc., during 2001–2014.

The top 30 most productive journals, which reported social media research during 2001–2014, accounted for 6.46% world share. A total of 266 were discovered as highly cited papers in social media research (0.57% world share), each was cited 100 or more times since publication till February 2015. Together these highly cited papers accounted 57462 citations, with an average of 216 citations per paper.

Highly Cited Publications Output by India in Materials Science Published during 2003–2012: A Scientometric Assessment

The main objective of this research was to identify highly cited papers in materials science and to analyze their publication and citation data to study their citation characteristics and to understand what role contributing authors, research organizations, as well as international collaborative players play in Indian materials science research. Indian materials science articles published from 2003 to 2012 were screened and highly cited papers, with at least 100 citations since publication, were identified and selected for a bibliometric analysis. The total number of papers, authorship, and collaboration statistics are presented for authors, institutions, foreign countries. To assess contributions, a new indicator, and the major contributor index (MCI) were used. Citation trends for all papers, as well as for top papers, are presented. A total of 396 highly cited articles, constituting 2.59% world share and 2.96% country share, were published by India in materials science output during 2003–2012. This study covered only those papers that received at least 100 citations since publication. In recent years, top-cited articles have reached their citation peak in the early years of their citation life cycle but have shown a more rapid decreasing trend compared to top-cited articles from the past decades. These 396 articles have received 68,668 citations, with an average citation per paper being 173.40. The leading Indian organizations participating in highly cited research were IISc-Bangalore (49 papers), NCL-Pune (29 papers), Jawaharlal Nehru Centre for Advanced Research-Bangalore (25 papers), Indian Institute of Technology (IIT)-Delhi and IIT-Kharagpur (16 papers each), Indian Institute of Chemical Technology-Hyderabad (15 papers), etc. The leading authors were C.N.R. Rao (20 papers), M. Sastry and V.K. Gupta (9 papers each), A. Govindaraj (8 papers), and A. Ahmad, V. Thomas, and C.D. Lokhande (6 papers each). The leading international collaborative countries were the USA (49 papers), Japan (27 papers), Germany (23 papers), South Korea (12 papers), and France (9 papers). MCI varied among leading institutions, as well as among individual authors. An indicator like the MCI can provide a proxy for the contributions made by an individual or institution. It reflects the independent research ability and leadership. In future evaluations of the institution or individual performances, the MCI should be included, together with the number of total papers, to provide a better profile of research performance.
