Knowledge creation and dissemination of new knowledge have become key words in the present day context of University education. The word “education” can have many meanings, but it has become something which is taught or learned by referring to available knowledge. The role played by higher educational institutions vastly differ from the traditional mode of delivering education, since seats of higher learning are the places where new knowledge is created in various disciplines. In other words we call them research & development. There cannot be any new knowledge without empirical research derived through critical inquiry. In spite of many developments in Research & Development, I am of the view that we Sri Lankans have not reached the heights that we are capable of scaling, up to this date. Therefore, the Universities should promote research and encourage more innovations that would leave a lasting impression in our society. Symposia of this nature make way for our teachers and students to transform their innovative ideas into scholarly work. It also helps the University to organize a gathering of similar minded scholars to meet each other and present their work, indulge in discussions and get necessary feedback. The Annual Research Symposium of the University of Colombo has now become a regular feature in the University calendar and the interest shown by our academics and students in this year's research symposium has shown us that they are keen on venturing ahead in their chosen areas of research. I would like to extend my best wishes to the organizers of the symposium, including its chairman Dr. Sampath Senevirathne, the presenters and the participants. I wish the Annual Research Symposium 2015 of the University of Colombo all success. Professor Lakshman Dissanayake Vice Chancellor 6 Proceedings of the Annual Research Symposium, University of Colombo, October, 2015 Message from the Chairman, Symposium Committee On behalf of the Organizing Committee, I warmly welcome and embrace the research community and the invited delegates for the inauguration session and the technical sessions of the Annual Research Symposium of the University of Colombo, 2015. This is the premier and flagship gathering of one of the finest and longest traditions of academic interactions in the country, spanning across eight broad disciplines representing education, fine arts, humanities, law, management, medicine and sciences. Annual research symposium provides a platform to exchange ideas, discover novel opportunities and partnerships, reacquaint with colleagues across faculties, and broaden the knowledge. This year the symposium is held from 25th to 30th October at the University of Colombo. In order to provide an inclusive platform for diverse research ideas, the organizing committee this year decided not to have an overall theme for the symposium. To represent the diversity within its community of freethinkers, each faculty, however came up with their own theme, which enhanced the colour and character of the symposium. About 120 abstracts represent this year’s symposium. All these abstracts underwent double-blinded peer review under the careful supervision of the editorial committee. I am pleased to have His Excellency Mr. Yashvardhan Kumar Sinha, High Commissioner of India to Sri Lanka as our Chief Guest and Professor Anthony Anghie, Professor of Law at the University of Utah, as the keynote speaker for this year’s symposium. I am sure that their vast experience at both regional and global levels will enrich our understanding of global governance and networking. I wish the very best and success to all the authors, especially the postgraduate students of this year’s research symposium, who, with their tireless research work of today, will lead the society of tomorrow. The real challenge and responsibility upon us is now to bring this knowledge to where it matters – to the policymakers and general public at large. Dr. Sampath S. Seneviratne Conference Chair – Annual Research Symposium 2015 University of Colombo 7 Proceedings of the Annual Research Symposium, University of Colombo, October, 2015 Address by Keynote Speaker Sovereignty and the challenges of global governance: A sketch of three regimes Tony Anghie S.J. Quinney School of Law, University of Utah It is a commonplace to say we are living in a `globalized world’. Our sense of identity, of who we are, has been transformed by the perception that we inhabit not only a national but global space. The Sri Lankan Ministry of Education web-site, for instance, speaks of training students to be `competent citizens’ while achieving excellence in `global society’. The Sri Lankan Ministry of Higher Education proclaims as its goals the ambition to make Sri Lanka a regional knowledge hub. If the space of the `global’ has assumed this immense significance, the question then arises. What are the rules that govern this space-the rules of `global governance’? Who makes these rules? What are the politics of rule making? If politics in the national sphere provides us with a model of how rule-makers can be held to be representative or accountable, what are the politics which apply in the realm of `global governance’? Classically, states create rules-international law-to govern the globe. The intensification of globalization however, has complicated this framework. New actors have emerged, wielding immense power
