In this volume we present a series of case studies exploring situations of intergroup communication in modern industrial society. These studies are instances out of which we seek to develop interpretive sociolinguistic approaches to human interaction which account for the role that communicative phenomena play in the exercise of power and control and in the production and reproduction of social identity. Our basic premise is that social processes are symbolic processes but that symbols have meaning only in relation to the forces which control the utilization and allocation of environmental resources. We customarily take gender, ethnicity, and class as given parameters and boundaries within which we create our own social identities. The study of language as interactional discourse demonstrates that these parameters are not constants that can be taken for granted but are communicatively produced. Therefore to understand issues of identity and how they affect and are affected by social, political, and ethnic divisions we need to gain insights into the communicative processes by which they arise.

However, communication cannot be studied in isolation; it must be analyzed in terms of its effect on people's lives. We must focus on what communication does: how it constrains evaluation and decision making, not merely how it is structured. We therefore begin with materials or texts collected in strategic research sites which exemplify the problems we seek to deal with.
