This monograph, based on the Language Management model, provides information on both the "simple" (discourse-based) and "organised" modes of attention to language problems in the Czech Republic. This includes but is not limited to the language policy of the State. This approach does not satisfy itself with discussing problems of language varieties but tries also to attend to issues pertaining to situations, functions, and other aspects of communication. While Part I deals with theoretical prerequisites of the study, Part II surveys ethnic communities which are resident in the territory of the Czech Republic, and Part III, the most extensive in the study, provides a description of the current state of the major varieties spoken in the country. It is suggested that a weak form of diglossia (Standard vs. Common Czech) is one of the major areas of problems within the Czech language. Among the other communities the Roma community presents most distinctly interactional as well as narrowly communicative problems. All non-Czech communities seem to be gradually assimilating to the matrix (Czech) community, particularly with regard to language. Part IV is devoted to the survey of language management in different situations. The authors particularly deal with changes that occurred after the Velvet Revolution of 1989 and resulted in intensive management in all domains of interaction. Part V presents individual observations on areas that have so far failed to attract systematic attention. Included are problems of the functions of communication, problems of communicative settings, problems of participants and networks, problems of the communicated content (such as politeness), problems of the message form and of channels of communication. This section also includes a discussion of problems affecting the use of electronic media. Finally, in Part VI attention moves to issues of theories of language management: the renowned Prague School Theory of Language Cultivation, the Communist Party theory of the 1950s to 1980s, and current theoretical stances. A Table of Contents is appended at the end of the monograph. (Contains 2 figures, 5 tables and 6 notes.)
