Dedication

This work is dedicated to my parents and grandmother who are always there for me.

To my beloved fiancée for her tolerance, support and endless LOVE

To my three lovely cats, Tong, Tung & Mo, who bring joy, fun and occasional noises to my life.

Acknowledgement

I would like to thank my supervisor Dr Maria Gonzales for her advice and guidance throughout my MSc course.

I am grateful to my dear friends Musheera Mohammad Ali, Chantal Suthananthan, Rameshwar Maharaj, Teresa Lai and Billy Lai.

Mushi cheered me up whenever I was worried about the thesis. Chantal provided me with fabulous food while I was struggling with my dissertation writing. Ramesh’s coffee is the best in Wales! Teresa and Billy always make me feel at home when I am in Cardiff.

After going through the MSc course, I have gained knowledge as well as confidence. More importantly, I enjoy this course with all these wonderful friends around me.
