Crisis communication in racial issues

On November 17, 1998, three individuals were detained by local police in Lubbock, Texas for attempting a pigeon drop scam in a Wal Mart parking lot. The three suspects were the head coach, an assistant coach, and the husband of the head coach from the visiting Hampton University women's basketball team. The three were eventually proven innocent and released, but not before a crisis involving racial overtones had been initiated. The case study explores the crisis management responses of Texas Tech University and Lubbock, Texas and the implications for the study of crises involving race.

This assignment also allows students to engage in critical analysis, which not only means that students can learn about rhetorical theory, but they also get to engage in the types of analysis used by their instructor during the course.

Communicating Knowing Through Communities of Practice: Exploring Internal Communicative Processes and Differences Among CoPs

Knowing is an enacted, communicated process that is difficult to observe, let alone manage, in organizations. Communities of practice (CoPs) offer a productive solution for improving knowledge and knowledge management, but the communicative processes that enact CoPs have not been explored, leaving CoPs as an organizational black box. This research extends CoP theory as a means to determine the presence of a CoP and distinguish between various CoPs, and as a practical means to evaluate the communicative processes of organizational knowledge. CoPs enact the communicative nature of knowing through the elements of mutual engagement, negotiation of a joint enterprise, and shared repertoire. Specifically, two groups of volunteers are examined through a combination of participation, observation, and interviews in order to explore CoP theory as a dynamic system for examining and evaluating organizational knowledge.     

Establishing the structure of reality for an industry: model and anti-model arguments as advocacy in Nike's crisis communication

This study illustrates the potential role of model and anti-model arguments in organizational crisis communication. Specifically, model and anti-model arguments are described as a strategy for moving the focus of a crisis from an organization to its industry. Model arguments enable organizations to establish their corrective action as industry standards that merit imitation. Conversely, organizations can set minimum standards for their industries with anti-model arguments. Phil Knight's May 12, 1998, speech announcing Nike's new initiatives in global manufacturing is analyzed as a case study. The essay concludes that model and anti-model arguments can suspend criticism of the organization, create the foundation for a return to industry prominence by the organization, and establish proposed new industry standards that are favorable to the organization.     

Teacher e-mail message strategies and students' willingness to communicate online

In light of the prevalent use of e-mail between teachers and students, researchers have highlighted the need to assess its uses and effects. Relying on the research and thinking of teacher immediacy and extra-class communication, we developed a scale that measures those e-mail message strategies that influence students' willingness to communicate online with their teachers. Next, we isolated those reasons that students use e-mail to interact with their teachers: (1) to clarify course material and procedures, (2) as a means of efficient communication, and (3) for personal/social reasons. Finally, we examined student characteristics such as gender and ethnicity, and history of e-mail use that may (or may not) influence their attitudes toward e-mail exchanges with teachers.
