Talk Radio, Discourse
Radio was the first electronic mass medium. It became a prominent part in people's every day experiences and in the discursive practices of mass media that followed in its wake. Moreover, radio was instrumental in creating communities around it and it has a central part in the public sphere. Key features of radio discourse include: intentionality, sociability, performativity, interactivity, and liveliness. There are many radiophonic genres; foremost among them is the phone-in, in which an ordinary person calls in to a program to talk with a host in front of the audience. The structure and features of phone-ins are illustrated to demonstrate how an institutional setting is achieved.

Identity, categorization and sequential organization: the sequential and categorial flow of identity in a radio phone-in
Radio phone-in programmes have been the subject of a number of studies using the methodology of conversation analysis. Although this has been successful in making apparent the sequential organization of this type of interaction, little has been said about its categorial organization. Adopting an ethnomethodological approach, it is demonstrated in this article that interaction on public access radio can be seen to rely upon categorial and sequential identities built up and developed upon over the course of interaction. By paying attention to the categorial features within media interaction, together with the sequential organization, it is possible to examine the way identities are reflexively developed in conjunction with the sequential flow of interaction. This in turn allows an analysis able to address the multilayered organizational methods used by members as part of the on-going flow of interaction.
Marketing the mpa degree: Access and program structure as determinants of successful enrollments
During the months of October through December of 1982, a national comparative evaluation of 186 MPA programs was undertaken to determine which variables are associated with enrollment strength across these programs. Two sets of variables, one corresponding to the structural characteristics of the program, the other corresponding to measures of access for these programs, were statistically analyzed. The findings are as follows: (1) the highest enrollments are determined by access to a market population and whether or not the program was located in a school of public administration; (2) there is a fundamental difference between programs oriented towards full-time students and those oriented towards part-time students; (3) full-time oriented program enrollments are dependent on structured characteristics of a program while part-time oriented programs are sensitive to access variables and not program characteristics and; (4) larger enrollments are associated with organizational autonomy with the lowest enroll...
