Contributions to Research
Acknowledgments
I am indebted to my former students, associates, colleagues, and friends for their precious collaboration, ideas, and accomplishments. I cherish their inspiring participation and encouragement in my search for whatever lies beyond the horizon of perception; call it the essence, or simply the unknown.
I am also grateful to the peoples and governments of Germany, France, Canada, Italy, Switzerland, the United States, and Singapore, for their precious support that enabled my education and career, and who provided me and my family with rich opportunities to live and to grow in their culture.
