    Nexus between carbon emissions, energy consumption, and economic growth: Evidence from global economies
    (PLOS ONE, 2023-06-23) Dissanayake, H; Perera, N; Abeykoon, S; Samson, D; Jayathilaka, R; Jayasinghe, M; Yapa, S
    Renewable energy holds a remarkable role in clean energy adaptation due to the much lower carbon footprint it releases compared to other fossil fuels. It also has a positive impact by slowing down the rate of climate change. The study has examined the links between renewable and non-renewable energy use, CO2 emissions and economic growth in developed, developing, and LDCs and Economies in Transition between 1990 and 2019 in 152 countries. Granger-causality has been used as the methodology to investigate the link between the variables. The findings of the existing studies on the relationship between the consumption of renewable and non-renewable energy sources and economic growth are inconsistent, indicating that there may or may not be a relationship between the two factors. Apart from having a few empirical studies so far have examined the link between the above-mentioned variables, analysis has yet to encompass all the regions in the four sub-groups discussed above. The results indicated that no Granger-causal relationship exists between GDP and REC outside of Economies in Transition. Additionally, the GDP and CO2 of all countries have a one-way relationship. Nevertheless, research indicates that GDP and CO2 have a bi-directional link in Economies in Transition, a uni-directional relationship in developing countries, and no meaningful association in developed and LDCs. Therefore, it is essential to emphasise actions to lower CO2 emissions and develop renewable energy while also stimulating the economy. Ultimately, more nations should choose renewable energy sources to build a more sustainable future.

    Does e-commerce really matter on international trade of Asian countries: Evidence from panel data
    (PLoS ONE, 2023-04-24) Shanmugalingam, P; Shanmuganeshan, A; Manorajan, A; Kugathasan, M; Pathirana, G. Y
    Over the decades, technology has become an essential indicator to actively participate in the economic growth of nations. The usage of technology and e-commerce had created a new pathway to improve trade in Asian countries. This study seeks to verify the linkage between e-commerce and international trade. The annual data for panel data regression analysis were collected from the World Bank covering 38 Asian countries for 11 years, from 2010 to 2020. This study applied a set of estimation procedures such as descriptive statistic, correlation matrix, stationary test (Levin–Lin–Chu test, Breitung test, Augmented Dickey Fuller test, Harris–Tzavalis and Im–Pesaran–Shin test), Kao cointegration test, autocorrelation test and heteroskedasticity test. The two-step system Generalized Method of Moments (GMM) estimator was employed for dynamic panel data analysis. Empirical findings show that e-commerce significantly impacts the international trade of Asian countries. Governments of Asian countries should employ policies related to telecommunication technologies for e-commerce improvement and realize/ reap potential benefits from international trade.

    Knowledge management implications in ERP implementations: Evidence from Sri Lankan Cases
    (IEEE, 2008-12-12) Suraweera, T; Mahagederawatte, S; Kahandawaarachchi, C; Hewamallikage, P; Periyapperuma, D; Adipola, M
    Knowledge management (KM) plays a major role in the success of implementing enterprise resource planning (ERP) systems in business organizations. This research aims to provide an in-depth understanding of ERP implementation processes in Sri Lanka. The major issues associated with KM in ERP implementations are brought into light and possible strategies for overcoming such issues are identified. The research builds on the work of Baskerville et al. (2006), and focuses on the importance of 'operational level' knowledge practices of capturing, integrating and sharing during ERP system implementations. Results of multiple case study interviews have been analyzed using cognitive maps to determine the issues deem to have a major impact on the success of ERP implementations. Some of the key strategies that can be used to overcome the problems associated with KM in ERP implementations are presented.

    Role of the Context in Intuitive Combination of Evidence
    (IEEE, 2008-12-12) Senaratne, D; Kulasekere, E. C
    Combination' in `Theory of Evidence' is merging evidence received from different sources to reduce the uncertainty one entertains regarding the problem in concern. Rules having different semantics and producing conflicting outputs are found in literature. Unfortunately proper guidelines are not available to select the combination rules suitable for a given problem. It has resulted in counter-intuitive use of the rules. Contextual information governs how the frames against which the evidence is expressed are related. It is however not embedded in the evidence and therefore not available to the agent applying the combination rule. This paper explores how contextual information can be extracted to be used for improving the intuitiveness of combination. It establishes a systematic way to extract contextual information, based on what the authors denote as hypothesis-level and frame-level inter-frame relationships.
