This book examines communication processes that occur among people, groups, organizations and societies when they interact with culturally different entities. It conveys basic principles in a foundations section, applied variables in an applications section and possible developments in a speculations section. A unique feature of this book is that it focuses on cross-cultural communication as a phenomena with relevance in domestic and international settings. Interaction among people from varied world cultures is recognized as having parallels with interaction among people from varied subcultures (representative of the aforementioned world cultures) within the United States. The author's work with various cross-cultural ventures have taken him outside of the United States on over 55 trips to all the continents except Antarctica. Most notable in that regard has been his work with the U.S. Air Force in China, in Cambodia as a Fulbright Scholar and at the East-West Center in Hawaii asa visiting scholar.
