To my parents, thank you for your unconditional support and unlimited love. Thank you for your prayers. I am honored to have you as my parents. To my soul mate, fiancée, and only love, Noor, thank you for your support and patience. I would like also to thank the University of Redlands and the faculty for the full support and guidance that enabled me to accomplish this project, especially the diligent advisor Mark Kumler, Ph.D., for his guidance and efforts.
