A. M. Abstract: This study aimed to statistically measure the potentiality of resources of Ecotourism on Gross Domestic Product of Sri Lanka and to direct the policy makers to appropriately identify the resources of ecotourism contributing to Gross Domestic Product of Sri Lanka. The data used in this study were collected from Sri Lanka Tourism Development Authority and Annual Report of Central Bank of Sri Lanka from the period of 1983 to 2013. The variables used in this study were CTR, ZGR, BGR, BMICHR, WPR, ETR and RGDP. CTR, ZGR, BGR, BMICHR, WPR, and ETR were used in this study as the independent variables. RGDP is used as the dependent variable in this study. The quantitative methodology used in this study was based on the econometric analysis using the Statistical Software of E-Views, Minitab and MS Excel in collaboration with the parametric analyses. The time series econometric techniques such as Augmented Dickey Fuller (ADF) for unit root test, Johnson co-integration test for the long run relationship, Granger causality test for causal relationships between the variables and Residual test for best regression model were used in this study. There was a positive relationship between BGR, BMICHR, CTR, ETR and RGDP and an inverse relationship was found between RGDP, WPR and ZGR. The value of R-squared was 0.9637 and DurbinWatson statistic was 0.6365. The residual was stationary along with all the other variables. The Granger causality test showed the different way causal relationships between all the variables. This study prominently suggested for the government and policy makers to keep on focusing on the economic policies to be designed for the promotion of ecotourism industry as one of the prospective sources for economic growth and development in Sri Lanka. 2016-12-01T00:00:00Z http://ir.lib.seu.ac.lk/handle/123456789/5275 Title: A study of climate changes in the coastal region: special reference on paddy production in Ampara district Authors: Ashraff, S. H. A. Abstract: Agriculture is a vital sector in Sri Lanka as it plays key role in GDP, export income and total employment. This sector contributes 7.42 percent and 15 percent to GDP and export income in Sri lanka, respectively, and also it provides employment to about 26.1 percent of the labour force exceeding the contribution of any other single sector (Central Bank of Sri Lanka, 2017). Agricultural production is vulnerable to variation in climate, which affects almost all the regions in the Universal. Using a collective cross-sectional data from major paddy producing regions in Ampara and Sri Lanka, the responsiveness of paddy production to average temperature and rainfall variation was analyzed. This study purposes to examine the relationship between rainfall and paddy production. Samplings from 100 farmer’s households had been gathered by questionnaire survey as primary data and the secondary data. Rainfall data of 135 years and 20 years / 40 seasons paddy cultivation data has been utilized to analyses the result. As the result, the study finds that through the 3, 5 years moving average had shown high drier seasons of the years. The paddy production was very high in Maha season but this was very low in Yala season because of the rainfall variability. Paddy yield under various climate change scenarios. Both average temperature and rainfall have concave, non-monotonic effects upon paddy production, which implies that variations in growing climate are likely to have negative effects on paddy production. It was found that modest increases in average temperature and variation in rainfall had only a small effect of unclear sign, but increases in average temperature beyond 2.010C were likely to have strong negative effects on paddy production. For example, 3.08oC increase in average temperature individually or in combination with changing rainfall can lead to approximately 32% yield drop in Sri Lanka and 26% in study areas of paddy production. 2016-12-01T00:00:00Z http://ir.lib.seu.ac.lk/handle/123456789/5274 Title: தொல்காப்பிய உரியியலில் நிகண்டுகளுக்கான அடிப்படைகள் Authors: ராஹிலா ஷியாத் 2016-12-01T00:00:00Z http://ir.lib.seu.ac.lk/handle/123456789/5266 Title: A study on perception of graduate teachers towards computer assisted instruction in Eastern province of Sri Lanka Authors: Jazeel, A. M. Abstract: The technological advancement has offered a plethora of opportunities in educational practices. Pedagogical delivery of lessons in most of the universities in the world has got reshaped and absorbed Computer Assisted Instruction (CAI) as means of modern learning and teaching process. Nonetheless, most of the teachers in Sri Lanka, if not all, seem to be reluctant to capitalize on this effective instructional strategy of computer assisted instruction instead of the conventional method of teaching. The objectives of this study are to find out the extent of attitude of the teachers towards computer assisted instruction (CAI) and to test whether significant mean differences exist in sub groups based on gender, subjects studied in degree level, locality of residence, and knowledge of computer. A self-prepared tool of attitude scale was employed and administered among teachers. The comparisons of mean scores were made by using “t” test. The results revealed that the extent of attitude among university teachers is mediocre and the selected factors have differential influence in attitude towards computer assisted instruction. 2016-12-01T00:00:00Z
