Research generates the kind of knowledge that makes innovations possible and it has a clear potential to make significant contributions to the quality of higher education. The research abstracts submitted for the symposium cover an impressive range of subjects and disciplines, a distinctive aspect of the Annual Research Symposium that makes it unique in the University of Colombo’s calendar. The Symposium provides an ideal opportunity to exchange new information and strengthen the bonds among different groups of researchers working in varied domains and disciplines. This year’s symposium is held under the theme of “Engaging with the Digital World in Higher Education.” At present, many changes in university teaching and learning are occurring due to the emergence of new state/private universities and the growth of digital technology. In this context, I hope the theme of this year's research symposium will provide an opportunity to re-think the future path of university education in Sri Lanka. It is my fervent hope that this year’s symposium would prove to be a productive research forum that will facilitate the exchange of new ideas and make a significant contribution towards the advancement of research culture in the University of Colombo. I would like to extend my best wishes to the Chairman and Organizing Committee of the Annual Research Symposium, the presenters and the participants. I wish the Annual Research Symposium 2018 of the University of Colombo all success. 1 2 MESSAGE FROM THE SYMPOSIUM CHAIR ANNUAL RESEARCH SYMPOSIUM 2018 Professor Sandagomi Coperahewa On behalf of the Organizing Committee, I warmly welcome you to the Inaugural Session and the Faculty Sessions of the Annual Research Symposium 2018. Every year, this is the premier academic congregation that brings together multidisciplinary research findings of the University of Colombo. The theme of this year’s Research Symposium is “Engaging with the Digital World in Higher Education” and each Faculty has its own theme which signifies its identity and discipline. This overall theme and individual Faculty themes recognize the rising importance of digital futures in higher education. Over 200 abstracts are included in this year’s Symposium after a double-blind peer review process, under the guidance of Faculty Editorial Committees. This indicates the diversity of research interests on broad disciplines of the University of Colombo – Arts, Education, Law, Management, Medicine, Nursing, Science and Technology. On behalf of the University of Colombo, I am thankful to His Excellency Mr. Bryce Hutchesson, Australia’s High Commissioner to Sri Lanka and the Maldives for gracing this occasion as our Chief Guest and Professor Henrik Hansson of Stockholm University for accepting our invitation as the Keynote Speaker. I thank the Vice Chancellor Senior Professor Lakshman Dissanayake for his guidance and support in organizing this event. I had a committed and dynamic team to help me in planning and organizing this Research Symposium. As Chair of the organizing committee, I take this opportunity to offer my sincere thanks to all academic and non-academic staff in the University of Colombo who have been working in different committees to make this symposium a reality. Special thanks to the SAR / Academic and Publications Branch for co-ordinating the work of all the sub-committees as the Convener of the Symposium Committee. I thank you all for your efforts, assistance and commitment. 3 INTRODUCTION TO THE CHIEF GUEST Bryce Hutchesson High Commissioner of Australia to Sri Lanka and the Maldives His Excellency Bryce Hutchesson was appointed as Australia’s High Commissioner to Sri Lanka and the Maldives in February 2016.
