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.     

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.     

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.     

Critical Communication Challenges For the New Century

This article, with minor modifications, was the author's presidential address to the 53rd annual conference of the International Communication Association. It presents several critical communication challenges for the early 21st century. First, it outlines the root causes of 3 classic divides that provide context for these challenges: theory versus practice, persuasion versus entertainment, and East versus West. The author suggests pathways toward syntheses of these divides, then discusses 3 communication challenges of particular interest to the author: legitimization and advancement of entertainment theory, redefinition and expansion of research on the digital divide, and development of a science of diplomatic communication.

Transition Metal Dichalcogenides for Sensing and Oncotherapy: Status,Challenges, and Perspective

Transition metal dichalcogenides (TMDCs) are increasingly being used for chemical sensing, biosensing, and tumor therapy on account of their diversity, biocompatibility, multifunctionality, adjustable bandgap, and excellent photoelectric characteristics. This review mainly discusses the effect of the elemental composition and structure of TMDCs on the performance of electrochemical, biofluorescence, and colorimetric biosensors. The applications of TMDCs in tumor therapies are reviewed here. Furthermore, the current challenges and future directions for developing TMDC-based theranostics are summarized.

Research Challenges for 3G and Paving the Way for Emerging New Generations

The first third-generation (3G) systems are going to be implemented within the year 2001. Academia and industry are, however, already looking for means to improve the system performance further. Spectral efficiency and higher data rate are the goal. In order to achieve this goal, several means have to be combined. The most important of these are interference cancellation and multiuser detection, optimum space-time processing and adaptive modulation and coding. In the future several wireless systems having different performance characteristics, system structure and parameters will exist. This heterogeneity will make the seamless handover from system to system difficult if not appropriately solved. 4G (fourth generation) is an acronym without any generally accepted concept. We describe some desirable goals and features of the 4G systems.

Staying Ahead of the Digital Tsunami: The Contributions of an Organizational Communication Approach to Journalism in the Information Age

This essay addresses the challenges facing journalism in the information age by advocating for the study of journalism from an organizational communication perspective. The communication field has maintained an illogical divide between journalism and organizational communication scholarship. First, I present an overview of subdisciplinary identities. Second, I argue for an organizational communication approach to the study of journalism and refer to an empirical study as an exemplar of this approach. Finally, I present ideas for future research regarding the study of journalism and these subdisciplines. This approach is applicable to settings like newspapers, television news, and other media organizations. Analyzing journalism from an organizational communication perspective can connect academic subdisciplines and aid practitioners in understanding a rapidly evolving media landscape.
