Her endless dedication, enthusiasm, and encouragement helped me in all the time of research and writing of thesis. I also like to thank Dr. Margaret Portillo for her patience and support. Their mentorship went beyond my thesis. Special thanks go to Professor Kijeong Jeon and Robert Irvine, the Executive Director of California Vocation Inc. Without their helps for conducting this case study in the COVE center, this thesis could not have been made. Also I must thank California Vocation staff members for their valuable insights about their clients. Finally, I thank my family and close friends for their continuous and unconditional support. This thesis could not have been made without their valuable insights. 4 TABLE OF CONTENTS page ACKNOWLEDGMENTS
