Applications in Applied Linguistics departs from a comprehensive concept that views Applied Linguistics as the application of findings, theories and methods of sciences related to issues of language and communication, and that distinguishes different modes of applications (practical vs. theoretical, and top-down, i.e. departing from science, vs. bottom-up, i.e. departing from a real-life problem). These different modes are exemplified by descriptions of different domains of application that often have a far reaching impact on societies and individuals. Narrowing down the range of problems with language and communication from the level of societies to that of groups and individuals, the contributions describe problem areas and applied linguistic ways of dealing with them in the fields of language policy and planning; language and communication in the legal sphere; communication of migrants in diaspora situations; language and communication in the media; and in the study of communication disorders.
