Item 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.Item Study on the factors affecting private investments in Sri Lanka(Department of Economics, Faculty of Social Sciences, University of Kelaniya, Sri Lanka, 2016) Kodithuwakku, D.S.; Jayawardana, Y.W.; Jayawardhana, M.N.; Muhandiramge, K.M.R.R.; Dulani, K.P.K.Today it’s widely accepted that private sector is a key engine of economic growth in any country across the globe. As a part of private sector, private investments also plays a greater role particularly within developing countries who are very much in need of capital resources as well as skilled labor, new technology and innovation in achieving faster growth. Sri Lanka still being a developing country is no exception to this. Therefore, considering the role of private investments in Sri Lanka, this study aims to identify the factors affecting private investments within Sri Lankan economy. The study was based on secondary data covering the period from 1975 to 2015. Findings derived from regression model and correlation coefficients of the study have revealed that real GDP growth, real exchange rate, inflation rate, budget deficit, foreign trade, foreign direct investment and liberalization factor are positively associated with private investments. It has further been identified that out of all the independent variables, foreign direct investment is the most affecting factor to private investments in Sri Lanka whereas the liberalization factor is the least affecting factor. The relationship between liberalization factor and private investments denotes the less importance of export and import industry in determining private investments in Sri Lanka. Therefore, in conclusion, this study emphasizes that foreign direct investment, real exchange rate and foreign trade play significant roles as factors in determining private investments.
