Publication Embargo Learning Style Preferences of Business Students in Saudi Arabia(IGI GLOBLE Scientific, 2024) Rajapakshe, WThis chapter describes different types of learning style models It further explores Saudi Arabian business students' behavior regarding their preferences for different learning styles, as defined by the VAK learning styles model. 138 respondents who registered for theoretical courses and 128 for mathematical courses participated in the study. The data was gathered using a VAK modality questionnaire. The analysis indicated an apparent inclination towards multimodal learning compared to unimodal learning, with visual learning being the most favored unimodal mode. Moreover, the results of the independent sample t-test reveal no statistically significant difference in preferences among students enrolled in theoretical modules and those enrolled in mathematical modules.Publication Embargo Addressing Academic Stress: Implications for Female Students in Saudi Arabia(IGI GLOBLE Scientific, 2024) Rajapaksha, WSaudi Arabia's higher education policies have propelled a surge in female enrollment, mitigating female unemployment and bolstering the Saudization initiative. This surge in national education has curbed reliance on foreign institutions and facilitated access to higher education for local high school graduates. However, despite these advancements, student dropout rates and academic underperformance persist. This study investigates the influence of stressors on academic performance among female students in Saudi Arabia. Findings indicate that academic stress and stressors related to personality significantly affect academic performance, while stressors linked to career paths do not exhibit a similar impact.Publication Open Access Regaining construction momentum(Sri Lanaka Economic Association, 2020-08) Jayathilaka, R; Gunaratna, K.

Poverty has been one of the most debated concepts in development economics and international trade, with the international focus on poverty reduction under Millennium Development Goals (MDG) drawing much attention to its definition and measurement. Over at least the last two decades, the definition of poverty has also been a central issue in policy making towards poverty reduction in developing countries. The reason for this is because poverty definitions and measurements have important implications for poverty reduction policies. A study of India and Peru, drawing on both national data and micro surveys, found that significantly different people were identified as poor in the two countries. This was determined according to two different measurements of poverty ranging from a narrow definition, in terms of the monetary capability, to a broader definition, in terms of the participatory approach adopted by the United Nations Development Programme (UNDP) (Ehrenpreis, 2006)Publication Embargo Case Studies: Use of Low Strain Transient Dynamic Response Method for Rock Socketed End Bearing Bored Piles(ASTM Compass, 2018-05-28) Kodithuwakku, T. H; Thilakasiri, S; Rathnayaka, AThe transient dynamic response (TDR) method has been introduced to pile integrity testing over several decades. The TDR method requires measuring both pile top velocity and force induced at the pile top by a small handheld hammer. Force and velocity information can be used to determine the pile condition near the top of the pile and the stiffness of pile-soil-rock system. It has been suggested by researchers that the dynamic stiffness at low frequencies obtained from the TDR method relates to the static stiffness of a pile. The static stiffness determines the initial linear region of load-displacement behavior of a particular pile. However, little attention has been paid to developing a correlation between the dynamic stiffness obtained from the TDR method and the static stiffness of a pile head. Therefore, systematic field tests were performed on rock-socketed end-bearing bored piles to determine both dynamic stiffness and static stiffness. The piles were tested using both high-strain dynamic load testing and low-strain pile integrity testing. Based on the field testing results, this paper suggests a correlation between dynamic stiffness and static stiffness. Furthermore, successful implementation of the TDR method on rock-socketed end-bearing bored piles is verified through case studies. In addition, the case studies show that dynamic stiffness and first resonant frequency could be used to identify the doubtful piles having low toe stiffness.Publication Embargo Predicting the academic performance of students using utility-based data mining(IGI Global, 2020) Liyanage, S. R; Kasthuriarachchi, K. T. SData mining in education has become an important topic in the sphere of influence of data mining. Mining educational data encompasses developing models, plotting data, and utilizing machine learning algorithms to derive patterns on educational data by attempting to uncover hidden patterns, create information for hidden relationships using educational statistics, and perform many more operations that are unfeasible using traditional computational tools. This research aims to identify the main factors that influence the academic performance of learners in tertiary education system in Sri Lanka. A conceptual framework and an analytical framework on factors affecting the academic performance was constructed with this aim. The analytical framework was then validated with the data collected from technology learners in a tertiary educational institute.Publication Open Access Improving the understanding of safe-sex behaviours with the use of two models in Health Psychology(Faculty of Social Sciences, University of Kelaniya, Sri Lanka, 2016) Abeysinghe, NHealth psychology, which is a branch of psychology, aims to understand human health (wellbeing, illnesses, and vulnerabilities) from a biopsychosocial perspective that takes the biological, psychological, and social aspects of life into consideration. This sub-discipline broadly emphases its role in health promotion and maintenance of health, prevention and treatment of illness, detection and focus on causes of illnesses, and overall improvement of the health care system. Health psychologists utilise a broad range of psychological theories and models developed within the sub-discipline for the above functions. This paper outlines how two theoretical models in Health Psychology, the Transtheoretical Model (TTM), and the Health Belief Model (HBM), contribute to the understanding of safe-sex behaviours. Unplanned pregnancies and sexually transmitted diseases are noticeable problems around the globe. Almost one million adolescent women aged 19 or under become pregnant each year in the USA alone (Ventura & Freedman, 2000), and the number of adolescents acquiring sexually transmitted infections (STI), including Human Immunodeficiency Virus (HIV), approximates to 3.5 million (Chambers, & Rew, 2003). In the UK the number of new diagnoses for STIs has increased from 63% over the last ten years (Health Protection Agency, 2008). In relation to homosexual relationships, there is still a high incidence of unsafe sex, mainly in the form of unprotected anal intercourse, despite the long number of years of health promotion and education aimed at this population (Crossley, 2000).Publication Open Access Where Ethics and Culture Collide: Ethical Dilemmas in Grief Work Following the Easter Sunday Attacks in Sri Lanka(Springer, Cham, 2021-05-23) Abeysinghe, N; Ekanayake, E. SThe success of mental health care for individuals and affected communities is strongly connected to the service providers' adherence to ethical standards of the profession. These ethical standards aim to ensure the safety, well-being and the best possible quality of service to the service users. As trainees and novice counsellors, these aspects are discussed and learned in detail during counsellor training programmes and other courses in mental health care. Continued professional supervision is considered an essential element of providing mental health care within an ethical framework by almost all the counsellor and mental health-care professional bodies in the world. Yet, this is practiced by few practitioners in low- and middle-income countries due to the shortage of trained, accessible, experienced supervisors. In this chapter, we discuss the importance of continued supervision in a changing sociocultural context to help mental health practitioners to be alert and prompt to safeguard the clients and ensure the best possible care for them when cultural aspects and ethical standards of client care are in conflict as they some times are.Publication Open Access Drawing in or ruling out “Family?” The evolution of the family systems approach in Sri Lanka(Springer, Cham, 2019) Ekanayake, E. S; Abeysinghe, NThis chapter traces the baby steps of family systems approaches (FSA) in Sri Lanka. It captures some of the early known discussions about FSA held between academics, development workers, practitioners and grassroots counsellors and shares with the reader their genuine questions, doubts, cautious enthusiasm and joyous discoveries. The chapter also provides insights into the sociocultural realities within which counselling services are offered, the nature of the mental health and psychosocial services (MHPSS) in Sri Lanka, the diverse players and the specific limitations and challenges that proponents of FSA would need to navigate. The reader is invited to experience two real-life events in which the authors have explored the adaptation and use of FSA together with their students, co-workers and trainees. The first is in a classroom where masters-level students of counselling experience FSA as a practical learning experience. The second shares explorations with field counsellors working directly with vulnerable family members of migrant workers. These two scenarios highlight the reasons for and the manner in which FSA has been chosen as a robust, flexible and powerful tool capable of addressing the demands of evolving family systems and a changing Sri Lankan society.
