Vaughn, Stanley W. Preston# Robert A. Rentz, James W. Pattillo, and Edmund R. Gray for their con structive council and encouragement. Professor Vaughn offered many helpful suggestions throughout this research work. His succinct comments frequently exposed the kernel of the situa tion and led to vast improvements in the overall content of this work. Both Professors Preston and Rentz gave freely of their time in'reviewing and commenting on early drafts of this work. Professor Preston was instrumental in directing my attention to•the topic of this research......... A note of appreciation is extended to two special individuals, Martin E. Rooney and Donald E. Kirsopp. Profes sor Rooney's method of research set the goal for this disser tation. Mr. Kirsopp wrote the first computer program used in this research and punched the first'cards. Finally, my total gratitude is expressed to my family. My parents, Anton and Imogene, and my brother, Tom, supported by educational endeavors. My wife, Jeane, typed the first draft and provided a climate conducive to intel lectual pursuit in an otherwise tenuous environment. My ii three sons, Mark, Trent, and Shane made the largest sacrifice; .they gave up their father for a period of over one year.
