Publication Embargo Accessibility and usability of virtual learning platforms: Lived experiences of visually impaired undergraduates in Sri Lanka(Elsevier Ltd, 2026-03-12) Rajapakshe, W; Wickramaarachchi, C; Alwis, M.K. S.S; Amarasinghe, A.A. M.L; Jayasekara, P.N; Jayasekara, P.TThis study explores the accessibility and usability of virtual learning platforms of visually impaired undergraduate students in Sri Lanka, focusing on their lived experiences, use of assistive technologies, and institutional support mechanisms. As online learning becomes increasingly prevalent, accessibility and inclusive challenges persist, particularly in developing countries with limited infrastructure and institutional support. Despite the availability of assistive technologies, visually impaired learners frequently encounter barriers, including poorly designed platforms, limited usability of screen readers, and inadequate institutional guidance. Addressing a critical research gap, this study investigates how visually impaired undergraduates experience and navigates virtual learning environments to identify accessibility barriers, enabling practices, and context-specific strategies for inclusive digital learning. Using a qualitative approach, semi-structured interviews were conducted with fifteen visually impaired university students across Sri Lanka. Thematic analysis revealed five core themes: barriers and challenges to effective virtual learning, preferred virtual platforms, accessibility features and tools, facilitators of learning success, and strategies to optimise the learning environment. These findings illuminate how systemic inequalities, infrastructural limitations, and institutional neglect collectively constrain the digital learning experience for visually impaired students, while also highlighting enabling practices that foster access and inclusion. The study's originality lies in foregrounding student-led insights in a developing country context and integrating practical, context-specific recommendations for platform developers, educators, and policymakers. By centering the voices of visually impaired learners, this research contributes unique and actionable knowledge to the field of inclusive digital education.Publication Embargo Long-term recovery from the 2004 Indian ocean tsunami in two Sri Lankan east coast municipalities(Elsevier Ltd, 2026-01) Thamboo, J; Josiah, R; Saja, A; Salah, P; Rossetto, T; Dias, PSri Lanka was the second most affected country after Indonesia, in the 2004 Boxing Day Indian Ocean tsunami (IOT). A study mission was therefore carried out twenty years after the 2004 IOT to assess the recovery of the affected regions, especially in the Eastern region of Sri Lanka, focusing on two of the most affected municipalities, i.e. Kalmunai and Batticaloa. The social and infrastructure characteristics of resettlements/relocations/new settlements in the affected regions, presence of critical infrastructure, preparedness and early warning systems installed have been assessed. It was observed that similar approaches have been adopted to plan the community relocation in both of these municipalities, while the significant reemergence of residential and commercial developments in the coastal stretches of Kalmunai municipality have been noted. Exposure analyses have revealed that there are still some critical infrastructure situated in the tsunami hazard zones. It can be construed that these municipalities have recovered from the physical losses incurred, and spatial planning is in place for future developments considering the tsunami risk. Challenges and opportunities from their differing geographical contexts appear to have been judiciously handled. However, shortcomings are noted in actual implementation due to various reasons, such as limited resources, availability of funding and preference of communities to live close to their original lands. Improving the resilience of infrastructure by designing against the expected tsunami hazard and multi-hazards, regular verification of the early warning systems and evacuation procedures are emphasized to mitigate the impacts from future tsunami.Publication Open Access Enhancing Mergers and Acquisitions (M&A) performance: Analyzing the role of human resource practices in Sri Lanka’s telecommunication industry through Lewin’s change management model(Public Library of Science, 2025-01-10) Pubodhya S.H.N.; Rajapakshe, WThis study explores the integration of sexual and reproductive health (SRH) education in Sri Lanka, utilizing the Health Belief Model (HBM) to predict the perceived quality of SRH education among non-state undergraduate students. In many Asian countries, including Sri Lanka, cultural resistance and skepticism often challenge SRH education initiatives. The research is based on a questionnaire survey, examining factors influencing the perceived quality of SRH education, such as cultural norms, embarrassment, attitudes, awareness, and institutional support. In recent years, the Sri Lankan telecom industry has experienced significant expansion and transformation, leading to a notable increase in mergers and acquisitions (M&A). This study investigates the impact of human resource practices on M&A performance, utilizing Lewin’s Change Management Model as a framework. The research is based on a questionnaire survey, examining factors influencing the performance of M&A in Sri Lanka Telecom industry, such as communication (Unfreeze), training (Change), leadership (Refreeze), and performance (M&A outcomes). Structural Equation Modeling (SEM) reveals that communication significantly influences training (β = 0.800), while training has a strong effect on leadership (β = 1.062), both directly and indirectly via communication (β = 0.850). Additionally, performance is positively impacted by training (β = 0.819) and leadership (β = 0.459), with communication exerting a substantial indirect influence on performance (β = 0.655). These results underscore the necessity for an integrated approach that enhances organizational performance and adaptability in an evolving business landscape. To optimize M&A outcomes, organizations are encouraged to prioritize leadership development, invest in comprehensive training programs, and align communication strategies effectively. This research contributes valuable insights into the management of change within the telecom sector, promoting sustainable growth and success in future M&A endeavours.Publication Open Access Sri Lankan SMEs’ Performance Through Cloud Computing Adoption: An SEM-ANN Analysis(Institute of Electrical and Electronics Engineers Inc., 2025-04-25) Nawaz, S.S; Thelijjagoda, SThis study identifies the determinants of cloud computing adoption and its effect on the performance of Sri Lankan small and medium-sized enterprises (SMEs). The Technology-Organization-Environment (TOE) framework, Technology Acceptance Model (TAM), and individual context were used to derive the study variables. This quantitative cross-sectional study adopted items from previous validated studies. Google Form was employed to collect data, and 418 responses were received from Sri Lankan SMEs. Partial Least Squares Structural Equation Modelling (PLS-SEM) via SmartPLS 4 and Artificial Neural Network (ANN) analysis via IBM SPSS 29 were used for data analysis. Based on the results, all hypotheses are confirmed except for one, and SME performance is significantly affected by cloud computing adoption. This study adds to the existing empirical evidence on cloud computing adoption by introducing an all-inclusive model that integrates the TOE, TAM, and individual factors. This demonstrates the effectiveness of the PLS-SEM/ANN hybrid methodology in analysing the determinants of cloud computing adoption. The significance of top management as a factor is highlighted by providing training and education to employees. Managers can benefit from this result by improving cloud computing adoption among SMEs in Sri Lanka. This is the first study of its kind in Sri Lanka, integrating the TOE, TAM, and individual variables and using a hybrid methodology combining PLS-SEM and ANN.Publication Embargo Navigating economic crisis: Factors shaping resilience in Sri Lankan construction SME supply chains(Taylor and Francis Ltd., 2025) Madhavika, N; Bandara, M; Manchanayake, M; Perera, C; Bandara, W; Jayasinghe, P; Ehalapitiya, SIn today’s construction industry, supply chains are subject to much greater disruption than they were in the past, resulting in a greater need for resilience. However, there is a gap in the literature that examines the resilience of construction small and medium scale Enterprises (SMEs) specifically focusing on developing countries. This article is a step towards identifying the factors influencing the resilience of construction SME supply chains taking the case of Sri Lanka: a developing country which is currently amidst a major economic crisis. This research study adopted a mixed-method approach, employing 08 structured interviews with employees ranging from executive level to top level management of 08 construction SMEs followed by a questionnaire survey considering a sample of 195 construction SMEs also with executive level to top level management of each construction SME. The findings indicated that Collaboration, Entrepreneurial Orientation (EO), Internal Integration, and Outsourcing have a positive significant impact on the resilience of Sri Lankan construction SMEs’ supply chains during an economic crisis, while ‘collaboration’ and ‘EO’ are the most influential factors respectively. Therefore, construction SMEs must prioritize and enhance collaboration and EO when devising supply chain strategies to strengthen resilience during economic crises. This paper contributes to filling the research gap by investigating factors influencing construction SME supply chains in a developing country during an economic crisis. Moreover, it contributes to the knowledge by being one of the latest empirical studies focusing on the construction SME supply chains in Sri Lanka. The findings provide a valuable reference for both policymakers and practitioners seeking to improve the resilience of construction SME supply chains.Publication Open Access The Potential of Arboreal Tiger Beetle (Derocrania scitiscabra Walker) as a Natural Enemy for the Control of Fall Armyworm (Spodoptera frugiperda JE Smith)(Faculty of Agricultural Sciences, Sabaragamuwa University of Sri Lanka, 2025-01-15) Kasige R.H.; Abeywardhana D.L; Pallewatta N; Perera M.T.M.D.R; Dangalle C.DPurpose: The fall armyworm, Spodoptera frugiperda, is a serious pest of maize, sugarcane, and other crops in Sri Lanka. Natural predators and parasitoids are considered the best methods to control this insect pest. The present study investigates the possibility of using an endemic tiger beetle, Derocrania scitiscabra, as a natural predator for the larval stages of S. frugiperda. Research Method: The feeding preferences of D. scitiscabra to live prey versus dead prey, live prey types including different instar stages of S. frugiperda were investigated in the laboratory using choice tests. Fresh minced meat was used as dead prey, while red ants, earthworms and the six larval instar stages of S. frugiperda were used as live prey. Findings: Red ants were the most preferred prey type of D. scitiscabra, and dead prey, earthworms and mature S. frugiperda larvae were not consumed. Early larval instar stages of S. frugiperda were selected as prey, and the beetle showed a high feeding preference for the second larval instar stage. This feeding preference was observed irrespective of whether red ants were present or absent in the same environment. D. scitiscabra may have selected the second larval instars of S. frugiperda due to their small size, high prey density, mobility, and being devoid of injury. Research Limitations: The tests were conducted under laboratory conditions in insectary facilities. However, field investigations are essential to understand the ecological dynamics that affect insect behavior and survival. Originality/value: An endemic beetle is introduced to control S. frugiperda infestations in their early stages of development. The finding may provide an environmentally safe and economically beneficial method to control S. frugiperda.Publication Open Access Prevalence, nature and impacts of non-sexual online harassment in Sri Lanka: A quantitative analysis(Elsevier Ltd, 2025-10-20) Harasgama, K. S.; Karunasena, K; Senarath, S; Jayamaha, S; Mahingoda, C.B; Deshapriya, WThe objective of this study is to examine the prevalence, nature and impacts of nonsexual online harassment among the youth population in Sri Lanka. Data was collected through a countrywide survey from a cross-sectional sample of 4805 young people. Data was analysed using SPSS software package. Results of this study indicate that 11.7 % of the youth population surveyed had experienced non-sexual forms of harassment in the cyberspace. The analysis also revealed the most common types of harassment experienced, the platform where harassment was committed the most, the most common types of victims and perpetrators, and the impacts of non-sexual online harassment on victims. The findings of this study suggest that Sri Lanka needs to devise targeted policies for combatting non-sexual online harassment, and that it may need to tailor its responses to the needs of each sector.Publication Embargo Decrypting the Digital Vault by Understanding Cryptocurrency Adoption Challenges Among Gen Z: Case of Sri Lanka(University of Nigeria Department of Mass Communication, 2025-01-01) Mallawaarachchi, S; Hemachandra, U; Jayakody, D; Wickramarathne, U; Lokeshwara, A.A; Bandara, G.CBackground: As digital natives, Gen Zs are at the forefront of embracing cryptocurrencies for technological innovation and financial empowerment.

However, in recent years, its overall share of the national output has declined, primarily due to the impacts of the COVID-19 pandemic, political instability, and ongoing economic challenges. Many construction firms halted projects and laid off employees, highlighting the critical need for effective risk management during crises to predict and mitigate risks. This study explores emerging risk factors in Sri Lanka's construction sector post-crisis. Using a three-phase linear decision-making model, the research combines a literature review, a survey of 290 construction professionals, and structural equation modelling (SEM) to identify major risk factors across four phases of risk management. Key risks out of 23 include general factors like health and safety issues, material costs, regulations, political interference, corruption, and labor shortages, while phase-specific risks involve delays, budget overruns, payment delays, and cancellations. The study revises the risk registers to improve risk management strategies. While the findings are context-specific to Sri Lanka, they may offer indicative insights for other developing countries facing similar crisis-driven disruptions. The practical implications extend to multinational and local companies, supported by data from 22 countries, offering a comprehensive framework for addressing construction industry challenges in volatile environments. The novelty of this study lies in its use of theoretical triangulation to align Classical Risk Management theory with real-world operational risk factors, revealing critical overlaps, behavioral influences, and contextual gaps in traditional frameworks.Publication Embargo Toward minority resilience – an integrated qualitative analysis with trans and gender non-conforming interviewees in Sri Lanka(Emerald Publishing, 2025-04-08) De Silva, R; Henrich, S; de Silva, B.G. R; Maycock, M; Edirisooriya, C; Nagahawatta, K; Medawatta, WPurpose – This study aims to explore minority resilience of trans and gender non-confirming individuals within a non-Western, collectivist society in Sri Lanka. Design/methodology/approach – In total, 15 interviews were analyzed with the multi-method qualitative text and discourse analysis framework; by incorporating the depth of discourse analysis with the breadth of thematic analysis. Findings – Four narratives emerged (jealousy and competition; authentic expression; othered or shunned; and conditional acceptance), located at the convergence of the two interview foci, “group membership” and “level of support”. Study findings strengthen the Transgender Resilience Intervention Model with evidence from a non-Western context, highlighting unique findings from Sri Lanka. Research limitations/implications – The sample size, focus on one nationality, exclusion of minors and recruitment of participants with access to digital devices may limit generalizability of study findings. Some responses on autobiographical data required prompting by the researcher, and retrospective recollections may not be reliable. Originality/value – To the best of the authors’ knowledge, this research is one of the first studies in South Asia to explore minority resilience with trans and gender non-conforming individuals. The findings add to the growing body of South Asian scholarship and further expand the predominantly Global North literature by providing a collectivist perspective.
