Item Embargo Personalized Adaptive System for Enhancing University Student Performance in Sri Lanka(Institute of Electrical and Electronics Engineers Inc., 2025) Dissanayake, N; Samarakoon, C; Wickramasinghe, D; Pathirana, M; Gamage N.D.U; Attanayaka, BThe growing need for personalized learning strategies has driven the development of data-driven solutions to meet the diverse needs of Sri Lankan university students. A key challenge lies in identifying optimal learning paths that align with individual capabilities, learning styles, and engagement behaviors to improve academic performance. While previous research has explored generalized learning models, these often fail to adapt to the specific demands of individual learners. Traditional strategies lack personalization, resulting in inconsistent learning progress. To address this gap, the research introduces an assistive, data-driven approach that leverages Self-Organizing Maps (SOMs), Adaptive Learning (AL), Content-Based Filtering, Graph Neural Networks (GNNs), and Social Network Analysis (SNA) to create optimized, personalized learning strategies. Clustering algorithms and predictive analysis were used to segment learners and deliver tailored interventions based on their behavior. The proposed system integrates advanced machine learning techniques to enhance student engagement and improve overall academic outcomes through personalized pathways.Publication Open Access Beneath the Sentence: A Deep Dive into Post-Homicidal Mentality and Coping Strategies on Sri Lanka’s Death Row Inmates(School of Psychology. Faculty of Humanities and Sciences, SLIIT, 2025-10-10) Madanayake, C; Perera, H; Samarakoon, C; Athapaththu, T; Attanayaka, A; Weeramanthrie, Y; Sandupama, T; Selvaratnam, N.D; Ponnamperuma, LThis study explores the post-homicidal mentality and coping strategies of individuals convicted of homicide and sentenced to capital punishment in Sri Lanka, a context marked by stressful conditions of incarceration and cultural stigma. Using Interpretative Phenomenological Analysis (IPA), in-depth interviews were conducted with six male inmates at Welikada Prison to understand how they perceive and manage their acts (i.e., homicide) and extended detention under the threat of the death penalty. The results showed a variety of signs of psychological distress after a homicide, such as guilt, anxiety, disorientation, and emotional numbness. In order to deal with guilt, control intrusive memories, and adapt to prison life, participants used coping strategies, particularly religious surrender, creative engagement, and moral reframing. According to these findings, death row inmates face significant psychological difficulties, and the correctional system in Sri Lanka urgently needs culturally competent mental health services and rehabilitative frameworks. The study contributes to the limited qualitative literature on the inner experiences of death row prisoners, offering insights for policy development and clinical practices aimed at supporting psychological adaptation in highly punitive environments.
