<P> Axiology is concerned with how values inform research and theory development . Most communication theory is guided by one of three axiological approaches . The first approach recognizes that values will influence theorists' interests but suggests that those values must be set aside once actual research begins . Outside replication of research findings is particularly important in this approach to prevent individual researchers' values from contaminating their findings and interpretations . The second approach rejects the idea that values can be eliminated from any stage of theory development . Within this approach, theorists do not try to divorce their values from inquiry . Instead, they remain mindful of their values so that they understand how those values contextualize, influence or skew their findings . The third approach not only rejects the idea that values can be separated from research and theory, but rejects the idea that they should be separated . This approach is often adopted by critical theorists who believe that the role of communication theory is to identify oppression and produce social change . In this axiological approach, theorists embrace their values and work to reproduce those values in their research and theory development . </P> <P> A discipline gets defined in large part by its theoretical structure . Communication studies often borrow theories from other social sciences . This theoretical variation makes it difficult to come to terms with the field as a whole . That said, some common taxonomies exist that serve to divide up the range of communication research . Two common mappings involve contexts and assumptions . </P> <P> Many authors and researchers divide communication by what they sometimes called "contexts" or "levels", but which more often represent institutional histories . The study of communication in the US, while occurring within departments of psychology, sociology, linguistics, and anthropology (among others), generally developed from schools of rhetoric and from schools of journalism . While many of these have become "departments of communication", they often retain their historical roots, adhering largely to theories from speech communication in the former case, and from mass media in the latter . The great divide between speech communication and mass communication becomes complicated by a number of smaller sub-areas of communication research, including intercultural and international communication, small group communication, communication technology, policy and legal studies of communication, telecommunication, and work done under a variety of other labels . Some of these departments take a largely social - scientific perspective, others tend more heavily toward the humanities, and still others gear themselves more toward production and professional preparation . </P> <P> These "levels" of communication provide some way of grouping communication theories, but inevitably, some theories and concepts leak from one area to another, or fail to find a home at all . </P>
