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, L
This 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.

E-Learning Assistive System for Deaf and Mute Students
(IEEE, 2022-12-09) Ranasinghe, P; Akash, K; Nanayakkara, L; Perera, H; Chandrasiri, S; Kumari, S
E-learning has become a popular digital platform among both students and teachers. When using an e-learning system, deaf-mute students can get significant benefits. It allows students to better grasp their studies by providing additional details. The major problem that the deaf and mute community encounters in the e-learning environment is that they are no longer attempting to enroll in normal institutions, which do not provide many facilities for them due to a lack of resources, a lack of learning facilities, and some social disturbances. To achieve that problem this system will translate the lecturer’s voice into text, map words with pre-created sign language animations, generate subtitles for lecture videos, clearly identify the face position of the lecturer, detect difficult words, track the hand gestures, and practice sign language so that it will increase learning resources, facilities, usability and help teachers to execute their teaching process through this platform. Therefore, normal institutions can use this system as their learning management system. It will approach deaf and mute students to enroll in normal institutions and do their studies as typical students.

Satellite Rainfall Products for analysis of Rainfall trends for Mahaweli River Basin
(SLIIT, 2022-02-11) Perera, H; Gunathilake, M. B; Rathnayakea, U
The presence of accurate and spatiotemporal data is of utmost importance in hydrological studies for river basins. However, limited ground-measured rainfall data restrict the accuracy of these analyses. Data scarcities can often be seen not only in many developing countries but also in the developed world. Therefore, much attention is given to alternative techniques to accomplish the data requirement. Precipitation data extraction from satellite precipitation products is one of the frequently used techniques in the absence of ground-measured rainfall data. The Mahaweli River Basin (MRB) is the largest river basin in Sri Lanka and it covers 1/6th of the total land area of the country. Mahaweli River is the heart of the country and the water of it is being used for many activities, including hydropower development, water supply, irrigation, etc. Therefore, analyzing rainfall trends of MRB is interesting and worthwhile for many stakeholders of the river basin. Therefore, this research investigates the suitability of Satellite Rainfall Products (SRP’s) as an alternative for Rain Gauge measured data in the MRB by performing trend analysis between the two datasets. Six precipitation products, namely PERSIANN, PERSIANNCCS, PERSIANN-CDR, GPM IMERG V06, TRMM-3B42 V7, TRMM-3B42RT V7 were extracted for 10-35 years for 14 locations of the MRB spatially distributed in the three climatic zones of the catchment. Non-parametric tests, including the Mann-Kendall test and Sen’s slope estimator tests, were used to detect the possible rainfall trends in precipitation products. Significant increasing trends were observed for both ground-measured and SRP’s in the annual scale while mixed results were observed in monthly and seasonal scales. The trends from ground-measured rainfall and SRP’s were compared and the suitability of SRP’s as an alternative technique was stated.
