Special thanks must be given to my dissertation supervisor, Dr. Guoxing Yu. I would like to express my admiration for his substantial knowledge in education. I was so lucky to have his insightful advices throughout the whole journey of dissertation. He is a respectable sage who enlightened my thoughts every time I encountered difficulties.
