perform a function outside the classroom--for example, to complain about or praise a teacher to a school administrator), and unorganized aggregates (i.e., masses of people). Primarily excluded from the definition of professional communication would be diary entries (discourse directed toward the writer), personal correspondence (discourse directed to one or more readers apart from their group affiliations), reportage or belletristic discourse (novels, poems, occasional essays--discourse usually written by individuals and directed to multiple readers not organized as a group), most intraclassroom communications (for example, classroom discourse composed by students for teachers) and some technical communications (for example, instructions--for changing a tire, assembling a product, and the like; again, discourse directed toward readers or listeners apart from their group affiliations)....Professional communication...would seem different from discourse involving a single individual apart from a group affiliation communicating with another such person, or a single individual communicating with a large unorganized aggregate of individuals as suggested by the term mass communication (Blyler and Thralls, Professional Communication: The Social Perspective, (pp. 197-198). Professional communication journals IEEE Transactions on Professional Communication The IEEE Transactions on Professional Communication is a refereed quarterly journal published since 1957 by the Professional Communication Society of the Institute of Electrical and Electronics Engineers (IEEE). The readers represent engineers, technical communicators, scientists, information designers, editors, linguists, translators, managers, business professionals and others from around the globe who work as scholars, educators, and/or practitioners. The readers share a common interest in effective communication in technical workplace and academic contexts. The journal's research falls into three main categories: (1) the communication practices of technical professionals, such as engineers and scientists, (2) the practices of professional communicators who work in technical or business environments, and (3) research-based methods for teaching professional communication. The Journal of Professional Communication is housed in the Department of Communication Studies & Multimedia, in the Faculty of Humanities at McMaster University in Hamilton, Ontario. JPC is an international journal launched to explore the intersections between public relations practice, communication and new media theory, communications management, as well as digital arts and design.
