ACKNOWLEDGMENTS
This thesis is due to the helpful contributions from supervisors, academic staffs and
colleagues.
I am indebted to Associate Professor Dr Seema W.D. Narayan, the senior supervisor, for
her intensive supervision. I, indeed, appreciate her instruction, suggestions, comments, editing,
and care for every steps of this thesis. The thesis started with useful research questions and
appropriate motivation; however, it was in a difficult to select the best methodology to quantify
these questions. It was that Professor Dr. Seema W.D Narayan has directed me to the relevant
methodology amongst alternatives. Moreover, I have drwan such important things from her
supervision, in which the most important thing is her technique in doing a research.
I would also thank Dr. George Tawadros, the co-supervisor, for his suggestions on the
issue of methodology. Dr. George Tawadros is enthusiastic lecturer to provide feedbacks on the
progress of thesis writing.
I would have great thanks to staffs from the School of Economics, Finance, and
Marketing; and the School of Graduate Research for their supports during the whole period of

addition, I especially thank Ms Prue Lamont, Ms Kalpana Lalji, Ms Esther Ng, Ms Claudia
