A cross - national analysis of scientific publications on environmental science among the SAARC countries with special reference to Sri Lanka: a scientometric study
(2016) Pratheepan, T.
The main objective of this study is to explore and compare the quantitative distribution and growth characteristics of SAARC countries' publications in environmental science from 1995-2014 based on Web ofScience database. It also provides a means for comparing the Sri Lankan effort in this area with that of SAARC countries. The total world's literary output reflecting all fields is 29,780,519 records during 1995-2014, which have published in 48 different languages written by 790,122 authors. The share of environmental science research is 493,375 papers constituting 1.66% of the world's research output, which have published in 14 (29%) languages by 197,511 environmental scientists. Total research output of SAARC countries in environmental science is 21,209 during 19952014.0ut of 21,209 publications of SAARC countries about 84% shared by India. Among the SAARC countries India, Pakistan, Bangladesh, Sri Lanka and Nepal possess a productivity rate of not less than I % of total literary output in environmental science. Afghanistan is the least productive country among eight SAARC countries. In general SAARC countries' relative research efforts are surpass the world average during 1995-2014, with slight fluctuations in terms of Modified Activity Index. In terms of quality indicators, countries have the following ranks: Sri Lanka> Pakistan >Bangladesh > Nepal> Maldives > Bhulal1 > India and > Afghanistan, where Sri Lanka and Pakistan occupies the position corresPonding with the highest quality, and India, Afghanistan the two corresponding to the poorest quality. According to international collaboration, each SAARC's partners are the leading economies in the world. SAARC countries' links show the sharpest pattern. of association with leading economies and underscores its position in this elite group. The thesis. ends with important recommendations for further improvement in research and development.
Influence of Age, Gender and Academic position in Scientific Productivity: A Large-Scale Analysis of Sri Lankan University Academics.
(Department of Library and Information Science, Faculty of Social Sciences, University of Kelaniya,Sri Lanka., 2017) Pratheepan, T.; Weerasooriya, W. A.
It is well known that there are large differences in the scientific production between academics. Relatively small proportion of academics or scientists contributes to the majority of the publications. There are factors influencing in scientific performance of researcher. Objective of this study is to investigatepublication rate of Sri Lankan academics in the university system by the gender, age and position. These factors are important variables when analyzing scientific productivity at the individual level. In the analysis, all academics were assigned to five major fields. The study was considered 4,300 academics in 14,550observations (i.e. publication numbers per years). Thus, there are on average almost three observations per person analyzed.Non-publishing personnel have not been included in the study as only people who have published article online or available in Google Scholar. This may be regarded as a limitation of this study as the inclusion of the non-publishing researchers could possiblyincrease the publication rate differences between genders, age groups and positions.Publication output has been measured as article equivalents per person per year. In this calculation, co-authored publications are fractionalized among the authors. Study identifies the relative importance of the different factors based on regression analyses (OLS) of each major academic field. Finding shows that academic position is more important than age and gender. In the fields analyzed, the regression model can explain 13.5–19 per cent of the variance in the publication output at the levels of individuals. This also means that most of the variance in publication rate is due to other factors.
Journal of the National Science Foundation of Sri Lanka (JNSF), 2011 - 2015: A Citation Analysis
(Department of Library and Information Science, Faculty of Social Sciences, University of Kelaniya, Sri Lanka, 2016) Pratheepan, T.; Weerasooriya, W.A.
Citation analyses of research in developing countries are interesting for various reasons. The situation of Sri Lankan is rather exceptional.The Journal of the National Science Foundation of Sri Lanka (JNSF) is the only Sri Lankan journal; indexed by the Journal Citation Report (JCR) from2010.This paper provides a citation network analysis of publications from the JNSF. The analysis covers publications in the journal from 2011–2015. The paper analyses the most published authors, most cited articles, uncited articles, most prolific authors, top institutions, collaboration profile of authors, and the nationalities of authors, that are most represented in the journal. 441articles were taken from the primary data source, the Google Scholar using Publish or Perish (POP) software. An analysis of 1056 citations was carried out using the POP online analytics tool and Excel. Results indicate that the 60% of JNSF research publications have received minimum of single citation.There are 998 authors have been contributed for 441 articles published during the study period in JNSF. In terms of collaboration profile, the JNSF’s authors show preference for “mega – authored” papers. Only 114 (26%) papers were single authored. The most cited article is Mosquito-lavicidal activity of some Sri Lankan plants written by Ranaweera, SS. published in 2013.
