This study could never have developed or been completed without the valuable contributions of many people. My learning experience at Cairo University, Faculty of Engineering, Architectural Department, has opened my mind to the fascinating field of urban planning. Through the teachings of M. Yousri Hasan, the powers of planning in its social and cultural context have been understood and appreciated. Without the academic insights and support of Sayyed Ettouny, who eloquently linked physical planning to social theory, my journey to the United States would have been more difficult.
At the University of Southern California, the liberal academic atmosphere allowed this study to mature into its present form. I would like to acknowledge the invaluable contributions of my U.S.C. professors and colleagues, especially Manuel Castells, who has helped define the scope of this study during his spring visits to Los Angeles.
Valuable assistance came from the Center for Telecommunications Management at U.S.C. in developing the questionnaire, reviewing the data base to locate panelists, and proceeding with the Delphi exercise, making our work much easier. Special thanks to Masoud Saghafi for his willing cooperation and cheerful support.
