Mapping Visual Studies in Communication

This essay documents the main currents of visual studies in communication. After a brief history of the emergence of the field, we review the record of published research in books and journals during the past 5 years, identifying major strains of theory, key issues, and topical categories. We then apply the strains of thought to classify papers presented at the ICA conferences, noting patterns and shifts across and within ICA divisions and interest groups. Based on these patterns, as well as on informal input from colleagues, we map the discipline formation of visual studies and identify trends in institutional development. We conclude by exploring future directions for the field now that the visual interest group has grown to become the Visual Studies Division of ICA.     

Popular Communication After Globalization

The study of popular communication is carried out in many disciplines and many sites. It is often haunted by anxieties over high culture versus low culture and authenticity versus commercialization. Rejecting those binaries in favor of the dominance of the latter term in each, this article initially defines popular communication as objects widely circulated by mass media, texts to which people are widely exposed. Such texts are themselves commodities, and the meanings the texts facilitate are key. Scholars of popular communication usually espouse a leftist political agenda. They focus on signs that reveal processes in social or psychological experience, although some studies focus more on forms of discourse. The article proposes that studies in popular communication may be distinguished by whether they focus on rhetor, text, or audience. It concludes by urging a stance of critical populism, more popular involvement by scholars, and a greater understanding of erotics, or desire, in our work.     

Organizational Communication: Challenges for the New Century

Organizational communication covers an eclectic mix of approaches, theories, and methodologies, developed within organizational settings or applied from other areas. The authors start their assessment of recent literature with 6 challenges for the field that have been delineated in previous reviews: (a) to innovate in theory and methodology, (b) to acknowledge the role of ethics, (c) to move from micro- to macrolevel issues, (d) to examine new organizational structures and technologies, (e) to understand the communication of organizational change, and (f) to explore diversity and intergroup aspects of communication. All 6 challenges implicate the importance of considering the intergroup level of analysis as well as the interpersonal and organizational levels, to undertake multilevel research in context, and to consider the role and place of voice in organizations. Finally, researchers must make their research ethical and consequential.     

Public Relations: State of the Field

Public relations is both a professional practice and a subfield of communication with its own research and theory base. Public relations is relatively young as an academic field, however, having developed identifiable theory in only about the last 50 years. The field of public relations is developing into a theoretically based area of applied communication that has the potential to inform several areas of communication/mass communication and to offer theoretic and conceptual tools useful in health, risk, and political communication, among others. Because many readers are unfamiliar with public relations theory and research, this article first reviews and summarizes theory-related scholarship in public relations, then categorizes and explains the theoretic trends in the field. The article concludes by demonstrating how one of public relations' theoretic/conceptual tools, issues management, can apply across all areas of applied communication.     

"Mass" in Communication Research

And so it came about that the study of communications was deeply and almost disastrously deformed by being confidently named as the study of "mass communication". …

Game Theory in Communication Research: A Reaction and Reorientation

Three major questions are raised concerning Bostrom's assumptions underlying his application of game theory to communication research. First, an individual can either seek to maximize his own self-benefit or to maximize the mutual group benefit, but he cannot do both simultaneously, as Bostrom indicates. Second, regarding the assumption that individuals consistently order their preferences according to an internal scale: the probability of consistency of preference, criterion valuation, and interval units of identical size is very small in real life situations. (An acceptable method of dealing with interval units, using ratios of differences, is described.) Third is the criticism that Bostrom focuses game theory on the solution of an interaction rather than on the communication process through which the solution is derived. In his rejoinder, Bostrom denies stating that individuals will interact to achieve their greatest mutual satisfaction—but that they ought to, and his purpose was to make possible an analysis of the degree to which particular communicative acts approached this “ideal.” To restrict game theory to conflict situations (as Beisecker, and past game theorists, have done) is to ignore a potentially valuable tool for communication research. The fact that communicative measurement is complex is not new, nor a valid reason for no attempt being made to accomplish it.

Communication Law and Policy: The State of Research and Theory

This essay describes the domain of research in communication law and policy. It is based on a content analysis of research published in the journal Communication Law and Policy (1996–2004), papers presented to the Communication Law and Policy Division at annual conferences of the International Communication Association (1997–2004), as well as consideration of other resources. The most frequent areas for research were media regulation, Internet policy, and freedom of expression issues. After reviewing recent literature on the first two topics, we identified and showcased two emergent categories deserving future attention: communication and the law (particularly fair trial-free press issues) and implications of the burgeoning consolidation of media ownership.
