    Understanding AI Chatbot Adoption in Education: The Role of Perceived Usefulness, Ease of Use, and Anthropomorphic Tendencies
    (Institute of Electrical and Electronics Engineers Inc., 2025) Vidarshika, W; Dayapathirana, N; Ranasinghe, A
    This paper aims to highlight the underlying factors influencing AI-based ChatGPT usage behavior, considering the role of anthropomorphic tendency. It addresses existing gaps in AI literature, which has underexplored the anthropomorphization of nonhuman agents with human features in AI-based teaching and learning. This study extends the Technological Acceptance Model (TAM) integrating anthropomorphism tendency on usage behavior of ChatGPT of undergraduates. Empirical examination with Structural Equation Modeling (SEM) revealed that perception of ease of use and usefulness positively impact on attitudes and attitudes positively impacts on AI ChatGPT usage behavior in higher education. Furthermore, the novelty brings for the study with the anthropomorphism tendency as a moderator positively moderates perception of usefulness and ease of use on AI ChatGPT usage behavior in higher education. As the main theoretical contributions of the study this study contributes for the Technological Acceptance Model (TAM) identifying perceived ease of use and usefulness towards attitude and usage behavior and bringing anthropomorphism tendency for the model as moderator as one of lack of focused area in extant literature in AI based ChatGPT. Also, this study provides valuable insights for the designers of AI based ChatGPT in embedding the humanistic feature in enhancing the usefulness and ease of use towards their attitudes and usage behavior

    Voice from the Control Room : Government Officials' Perspectives on How Politics, Funding and Technology Shape Sri Lanka's Transport Future
    (Institute of Electrical and Electronics Engineers Inc., 2025) Bandara, S; Perera, Y; Premathilaka, H; Wijethunga, J; Karunarathna, N; Dayapathirana, N
    The daily struggles of Sri Lanka's public transpo rtation system affect millions of lives, yet the voices of those who run it often go unheard. This study spoke with eight senior government officials from the National Transport Commission and Ceylon Government Railways to uncover what happens behind the scenes. Through detailed interviews, three main problems weighing on their minds were identified: political interference disrupts their work, money shortages block necessary improvements, and finally, worker satisfaction has hit rock bottom. Many transport workers feel stuck with low wages and unclear career paths, which makes it hard to keep services running smoothly. However, it is not all about bad news. These officials shared smart ideas about fixing issues, from better resource management to innovative technology implementation that could help riders track their buses and trains. They believe Sri Lanka's public transport can improve with the right changes. This research study goes beyond just listing problems - we talked to people who live these challenges every day and know what needs to change. Their stories show that improving public transport is not just about new buses or trains; it is about supporting the people who keep everything moving, listening to what riders need, and Equipping transport workers with the required equipment to perform their jobs well.

    The impact of video game addiction on aggressive behaviour among tertiary students in Sri Lanka
    (Discover, 2026-01-30) Fonseka, W.Y.S; Hathurusinghe, B.M; Weerarathna, R.S; Rathnayake, R.M.N.M; Samindika, H.R.T; Ramasingha, L.T.D; Jayasuriya, N.U; Kumarapperuma, C; Dayapathirana, N
    This research examines the impact of video game addiction on aggressive behaviour of tertiary students in Sri Lanka. Video game addiction, with its potential adverse impacts has raised concerns among the public, especially regarding its link to aggressive behaviour. Data was gathered from a sample of 382 undergraduates of local non-state universities selected employing cluster sampling technique to examine the correlation between video game addiction and aggression. The survey was conducted to collect data on video game addiction and aggression. Research findings reveal how gaming addiction leads to aggressive behaviour in addicted gamers indicating a strong positive relationship between video game addiction and aggressive behaviour. Therefore, researchers recommend balanced time management practices between game usage and other daily essential activities and promoting awareness about negative behavioural implication of game addiction. It is expected that this study provides insights to stakeholders including teachers, parents, and administrators to better understand the effects of video game addiction, and mitigation strategies to minimise the negative impact on students’ behaviour.

    Restoring life expectancy in low-income countries: the combined impact of COVID-19, health expenditure, GDP, and child mortality
    (BioMed Central Ltd, 2025-03-06) Karunarathne, M.; Buddhika, P; Priyamantha, A; Mayogya, P; Jayathilaka, R; Dayapathirana, N
    Background: Life expectancy is a vital indicator of a country’s health and progress. Low-income countries face uncertainty regarding the long-term impact of the COVID-19 pandemic, driven by health expenditure levels, concerns over rising child mortality rates, and decreasing per capita income. These factors challenge life expectancy and demand urgent attention. This study aims to identify patterns, challenges, and opportunities to improve life expectancy in these countries through better health policies and resource allocation. Methods: The research investigates the impact of the COVID-19 pandemic, health expenditure, per capita income, and child mortality rates on life expectancy in low-income countries. By examining 22 years of data from 20 countries, using a comprehensive dataset from the Our World in Data database, this study employs panel regression and time series analysis to explore how these factors influence life expectancy. Results: The findings indicate a significant negative effect of COVID-19 on life expectancy, while health expenditure and per capita income show a positive impact. Conversely, child mortality rates exert a negative effect on life expectancy in low-income countries. Conclusion: This research contributes to the existing body of knowledge by analysing how COVID-19, health expenditure, per capita income, and child mortality collectively affect life expectancy in low-income countries. The insights gained may inform policymakers and health consultants about the need for targeted interventions, prioritising healthcare investment and child health. By addressing these critical areas, it may be possible to improve life expectancy and overall health outcomes, thus contributing to global health equity. © The Author(s) 2025.
