Factors Influencing University Riots: A Study on a Few Selected Sri Lankan Universities
(Emerald Publishing, 2022-12-01) Mendis, A; Yapa, S
This study is conducted to understand the factors influencing student university riots in a few selected universities in Sri Lanka. The aim of the research is to identify factors that impact and cause student riots in the Sri Lankan context. Student riots are the cause of many violent and uncontrollable events that affect both universities and the public. This study will provide quantitative analysis to identify the factors that influence that cause student riots within Sri Lankan universities. This area has been studied within the Sri Lankan context, but very limited factors were found that generally cause student unrest. Some of these factors found in Sri Lankan studies that were factors that caused student unrest were differences in ethnicities, extremist ideologies, and social networking. For the data collection and analysis, a questionnaire will be distributed among 375 students in various public universities in Sri Lanka with a focus on the Western Province which consists of three districts: Colombo, Gampaha, and Kalutara. This research will potentially help academic policy makers to understand their student bodies more and create more effective policies to mitigate student unrest by understanding identified factors that influence student university riots in Sri Lanka.

The interconnectedness of energy consumption with economic growth: A granger causality analysis
(2024-09-15) Perera, N; Dissanayake, H; Samson, D; Abeykoon, S; Jayathilaka, R; Jayasinghe, M; Yapa, S
In considering today's energy challenges, the link between the usage of renewable and non-renewable energy sources and economic growth has gained substantial policy attention. This research examines the complex relationship between these three variables to understand how non-renewable energy consumption and renewable energy consumption interact and what that means for economic growth. This study uses the Granger causality approach to explore the relationships between non-renewable energy consumption, renewable energy consumption, and economic development. It draws on a comprehensive dataset from the Word Bank database, including 152 nations from 1990 to 2019. The analysis is further disaggregated by four subgroups of countries; least developed, developed, transitional economies and developing countries. The result of this study provides valuable empirical evidence of uni-directional causality running from renewable energy consumption to economic growth and non-renewable energy consumption to economic growth in transitional economies. Furthermore, policymakers should focus on both variables when making decisions because the results show that energy consumption and economic growth are interconnected. Implementing global energy efficiency standards, reducing fossil fuel usage, and adopting regulatory measures are all viable policies for limiting adverse effects on the environment while encouraging economic development.

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.

Renewable energy as a solution to climate change: Insights from a comprehensive study across nations
(PLoS ONE, 2024-06-20) Attanayake, K; Wickramage, I; Samarasinghe, U; Ranmini, Y; Ehalapitiya, S; Jayathilaka, R; Yapa, S
Without fundamentally altering how humans generate and utilise energy, there is no effective strategy to safeguard the environment. The motivation behind this study was to analyse the effectiveness of renewable energy in addressing climate change, as it is one of the most pressing global issues. This study involved the analysis of panel data covering 138 nations over a 27 year period, from 1995 to 2021, making it the latest addition to the existing literature. We examined the extent of the impact of renewable energy on carbon dioxide over time using panel, linear, and non-linear regression approaches. The results of our analysis, revealed that the majority of countries with the exception of Canada, exhibited a downward trend, underscoring the potential of increasing renewable energy consumption as an effective method to reduce carbon dioxide emissions and combat climate change. Furthermore, to reduce emissions and combat climate change, it is advisable for nations with the highest carbon dioxide emissions to adopt and successfully transition to renewable energy sources.
