Influencing Factors of Resilience of Construction Supply Chains: A Case of SMEs in Sri Lanka
(SLIIT Business School, 2023-12-14) Manchanayake, M; Bandara, M; Sandhakirani, C; Bandara, W; Madhavika, N; Jayasinghe, M; Ehalapitiya, S
This research paper aims to explore the factors influencing supply chain resilience in Small and Medium-sized Enterprises (SMEs) operating within Sri Lanka's construction industry during economic crises. The study employed a qualitative approach. Data were collected using purposive sampling with a sample size of eight SMEs in the construction sector registered under the National Enterprise Development Authority of Sri Lanka. Using structured interviews, data were collected, and the responses were analysed using the Manual Thematic analysis procedure. The study findings states that collaboration, entrepreneurial orientation, internal integration, and outsourcing have been the main factors that have contributed to making the Sri Lankan construction supply chains resilient during Economic crisis. Therefore, it is recommended for the construction firms to focus and improve the presence of these factors in their respective supply chains, to make the supply chains more resilient. This study's significance lies in its focus on construction SMEs in Sri Lanka, offering insights from the perspective of manufacturers, which has been relatively unexplored in existing resilience related research. Although some research articles do touch upon this area, mostly these studies have been conducted in developed nations. Thus, this study contributes to the scant Sri Lankan supply chain resilience literature. Sri Lanka is making strong efforts to support its economy to combat the economic downturn and stabilize. Therefore, the findings of this paper will undoubtedly be useful for the Sri Lankan construction sector while aiding the country to flourish again.

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.

Twin Flames of Love and Friendship: Exploring the Immortal Bond of Catherine and Heathcliff in Emily Brontë’s Wuthering Heights
(Faculty of Humanities and Sciences, SLIIT, 2023-11-01) Jayasinghe, M; Hafsa, S.F
Emily Brontë’s Wuthering Heights is a renowned work in English literature that delves into the complexities of the human condition during the Romantic Era, tackling issues of profound social and emotional significance. This research paper meticulously examines the relationship between the male and the female protagonists, Heathcliff, and Catherine Earnshaw, viewing them as flawed yet deeply human individuals who grappled with various barriers that kept them apart. The evidence from the novel reveals that Catherine and Heathcliff’s shared upbringing instilled nearly identical attributes in them, leading to a lifelong struggle to retain their former closeness and compelling them to make agonizing sacrifices for each other. This paper would be studying if the Platonic concept of “Twin flames,” which is presented as an almost primal desire for two individuals to become one, by forging an unbreakable bond and an unparalleled friendship that transcends their earthly existence could be applied to the principal characters to explain their strong ties.
