ACKNOWLEDGEMENTS
I would like to express my deepest appreciation to my supervisor, Dr.
Nguyen Thi Bao Trang, for her insightful comments, direction, advice,
support, encouragement, and prompt feedback during my research
work. Without her guidance and persistent help, this dissertation would
not have been possible.
I would also like to extend my profound gratitude to the lecturers and
professors of University of Foreign Languages and International
Studies, Hue University for their devoted and patient guidance of me as
I undertook my programme of study. I greatly benefited from their
assistance, encouragement, and willingness to participate on academic
committees. Their comments on my dissertation led to a wealth of
valuable advice that helped me finish my research.
I am incredibly grateful to my colleagues, the students and the alumni
at the research sites for their participation in the study as well as their
enthusiastic support. The dissertation could not have been completed
without their excellent involvement.
I am also thankful to my friends for their generous support and
encouraging words they gave me during my trying times. I would not
have been able to focus on my studies and get through my ups and
downs without their help.
Last but not least, my sincere gratitude goes to my family. Their
unwavering love, understanding, encouragement, and support over time
and distance help me fulfill this study.
