    Economic and Environmental Drivers of Carbon Emissions in Asia: Granger Causality Insights From Foreign Investment, Inflation, and Ecological Footprint
    (John Wiley and Sons Ltd, 2026) Nizar, S; Natkunarasa, A; Divyanjali, H; Jayathilaka, R
    Rising carbon emissions cause critical challenges to sustainable development, particularly in Asia which accounts for a substan-tial share of global emissions. The study investigates the short-run causal relationships between foreign direct investment, infla-tion, ecological footprint, and carbon emissions across 27 Asian countries (final analytical sample) over the period 2000–2023.Utilizing country-specific VAR-based Granger causality analysis, the study captures heterogeneous sustainability economic in-teractions without imposing uniform panel assumptions. The results reveal diverse unidirectional and bidirectional causalitypatterns, highlighting how macroeconomic pressures and environmental constraints jointly shape emission outcomes. Thesefindings underscore the importance of sustainable investment, energy price management, and institutional capacity in sup-porting sustainable communities and enhancing knowledge-driven sustainability transitions. From a managerial and policyperspective, the results provide actionable insights aligning with investment decisions, macroeconomic management, and envi-ronmental governance with the sustainable development goals, particularly SDG 13 (climate action), while recognizing country-specific development pathways.

    A Comprehensive Review of Most Influential Risk Factors for Dementia among Elderly People in Asian Countries
    (School of Nursing, Faculty of Humanities and Sciences, SLIIT, 2025-10-10) Ranaweera, G; Dasanayake, C; Kanchana, T
    Dementia is characterised by a group of symptoms that are typically defined by memory loss, behavioural changes, and the subsequent loss of cognitive and social functioning caused by progressive neurological disorders. It represents one of the greatest global challenges for health and social care in the 21st century. This review aimed to identify the most influential risk factors for dementia among elderly populations in Asian countries.

    Common Risk Factors for Postpartum Depression among Mothers after Childbirth in Asian Countries: A Systematic Review
    (Faculty of Humanities and Sciences, SLIIT, 2023-11-01) Ranasinghe, N. S.; Wijedasa, H. S.; De Silva, B. S. S.
    Depression is the most common mental illness which leads to various health consequences among mothers following the delivery of their babies. Post-partum depression leads to self-harm, suicidal ideation, or harming the newborn, hurting family life. Early detection and management of depression during the antenatal period would prevent both maternal and neonatal complications. Hence, knowing the risk factors may help in planning care for individuals reducing the burden on the health care system. There is a lack of exact evidence of the common risk factors for developing depression after childbirth in Asian mothers. Therefore, this systematic review aims to identify the common risk factors for post-partum depression among mothers after childbirth in Asian countries. Relevant literature from 2017 to 2023 was searched in CINAHL, MEDLINE, PUBMED, Science Direct, and Cochrane databases. Seven highly relevant articles were selected using the PRISMA flow chart. Critical Appraisal Skills Programme (CASP) and its tools were used to carry out the critical analysis of each selected article. Following the in-depth analysis, three key themes were derived: an unfriendly home builds an unhappy mother, expectation versus reality leads to depression, and poor financial status leads to an unsafe post-partum period. The study highlighted that mothers in Asian countries are affected by a wide variety of complex post-partum depression risk factors. Improving knowledge, early detection of emotional needs, counseling, effective use of contraceptives, and delivery of high-quality care during the ante-natal period are necessary for reducing post-partum depression among antenatal mothers.

    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.

    Reasons for Cessation of Exclusive Breastfeeding in the Asian Countries: A Systematic Review
    (Faculty of Humanities and Sciences,SLIIT, 2021-09-25) Pathirana, R. P. N. D; De Silva, B. S. S
    Breastfeeding is the most cost-effective intervention in infant nutrition which also can prevent common childhood infections. This systematic review aims to explore the reasons for the cessation of exclusive breastfeeding in Asian countries. A literature search was carried out in electronic databases such as PubMed, CINAHL, Discover and Medline. Out of 590 research studies found, eight studies were selected for the systematic review using the PRISMA flow chart. When analyzing those studies, they were categorized under three main themes, such as factual or perceived insufficiency of breast milk, poor consecration by the mother, influence from traditions, customs and an unsupportive working environment that making breastfeeding impracticable. This systematic review suggested that intervention programs to improve exclusive breastfeeding in the Asian region should focus on promoting female nutrition and positive social attitudes towards exclusive breastfeeding. The intervention by the relevant governments is recommended to establish by law, a supportive working environment for exclusive breastfeeding.
