The selected articles are based on contributions prepared for the 17th International Linguistic Agency University of Duisburg Symposium on 23-27 March 1992. The 13 papers focus on problems and issues of intercultural communication. The first part is devoted to theoretical aspects related to the interaction of language and culture and deals with the issue from anthropological, cognitive, and linguistic points of view. Part II raises issues of language policy and language planning such as the manipulation of language in intercultural contact; it includes case studies pertaining to multilingual settings, for example in Africa, Australia, Melanesia, and Europe.
