It is my privilege to extend my deepest thanks for my dissertation supervisor, for supporting me, guiding me and motivating me throughout the process of conducting this research. I express my sincere gratitude to my supervisor for her continuous support in pursuing this research and in writing this thesis and for her valuable suggestions in accomplishing my dissertation work. Working under her guidance has helped me to transform myself as a professional and I extend my gratitude for sharing her knowledge. This journey could not be possible without the help of my supervisor. I am more thankful than I can express.
