    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.T
    This 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.

    From Tourism Growth to Sustainable Development: A Causality Analysis of Tourism, Exchange Rates, and Economic Growth in Asia
    (John Wiley and Sons Ltd, 2026-02-04) Wickramaarachchi, C; Jayathilaka, R
    Tourism is widely recognised as a catalyst for sustainable development, particularly in regions where it supports employment, foreign exchange earnings and local entrepreneurship. However, the extent to which tourism contributes to sustainable development depends on macroeconomic stability and policy environments that enable long-term investment rather than short-term revenue maximisation. This study examines the causal relationships between tourism receipts, per capita GDP (PGDP), and exchange rates across 46 Asian countries from 2000 to 2020, while controlling for trade openness to account for broader external sector exposure. Employing a panel data framework that accounts for cross-sectional dependence, heterogeneity, and mixed integration properties, the analysis combines second-generation unit root and cointegration tests with country-specific Granger causality techniques. The findings reveal substantial heterogeneity in causal dynamics across countries. In some economies, tourism-led growth emerges, where expanding tourism receipts stimulate economic growth. In others, economy-driven tourism dominates, indicating that rising income levels facilitate tourism development through improved infrastructure and destination competitiveness. Exchange rate stability plays an important conditioning role, shaping the extent to which tourism revenues translate into sustained development gains. Countries characterised by stable exchange rate environments are better positioned to channel tourism income toward long-term, sustainability-oriented investments. The study offers actionable policy insights by demonstrating that macroeconomic stability is a prerequisite for sustainable tourism development. Strengthening exchange rate governance, promoting eco-friendly tourism investment, and enhancing regional cooperation can support a transition from growth-oriented tourism strategies toward sustainable development pathways.

    Sustainable food waste management: A cross-country study of Australian and Sri Lankan hotel sector
    (Elsevier Ltd, 2025-12) Jayasuriya, N; Wickramaarachchi, C; Wijesundara, H; Sriyananda, U; Rathnayake, V; Liyanage, T
    Food wastage constitutes a critical global issue, with an estimated one-third of the food produced worldwide being wasted annually. The hotel sector represents a key contributor to this problem; however, it has received limited attention in the existing body of research. Therefore, this study seeks to undertake a comprehensive analysis of the underlying drivers of food wastage, the challenges encountered, and the strategies implemented to mitigate this issue within the hotel industry. Addressing the different contexts in developed and developing countries, this study has selected hoteliers in Australia and Sri Lanka. Data was collected from 20 hotel employees from both countries who are responsible for food handling and were analyzed thematically. The findings identified transportation waste, kitchen waste, and consumer waste as critical points of food wastage. Additionally, the role of technological equipment, combined with food safety precautions and regulatory measures, emerged as pivotal in managing food waste. These aspects are examined in detail alongside proposed mitigation strategies. Even though hospitality sector is largely contributed to these issues, the studies conducted on this sector in relation to the food wastage is very limited. Thus, this study focuses on filling the void in the literature by conducting an in-depth investigation on this topic.
