Editor's introduction to the forum on defining applied communication scholarship

Although public meetings are a frequent method of public participation and risk communication, little research investigates what citizens think about their use in environmental management. To examine satisfaction with public meetings, residents of two neighboring communities received questionnaires following a public meeting about a local landfill. Respondents included residents who did and did not attend the meeting. Irrespective of whether respondents had ever attended a public meeting, meeting expectations and perceptions of relational/informational communication at meetings, including whether respondents thought meeting organizers were genuinely interested in participants' comments or meetings were informative, predicted satisfaction. Perceived risk associated with the recent meeting's topic and credibility of government agencies that frequently conduct meetings also predicted satisfaction.     

The Anonymity Effect: The Influence of Anonymity on Perceptions of Sources and Information on Health Websites

The study reported here examined the influence of anonymous sources on health websites on the perceptions and attitudes of information seekers. It was hypothesized that, despite the warnings and guidelines established by health organizations, anonymous sources would be perceived to be as credible and influential as sources that were identified. The anonymity effect, drawn from the similarity principle in attribution theory, was forwarded as a theoretical mechanism to explain responses to anonymous sources. The results indicated that anonymous sources were generally perceived by participants to be as credible and influential as identified sources, although the anonymity effect explanation was not supported. The implications of these findings for information seekers and health practitioners are considered.     

Redefining Hijab: American Muslim Women's Standpoints on Veiling

Feminist standpoint theory suggests that, although powerful discourses attempt to define women on the “margins” of society, women's cultural positions provide them with heightened understandings of the contradictions between their experiences and the ways the dominant group defines them. Thus, while many Americans believe hijab—also called a “veil” or “headscarf”—functions to oppress women, veiled women probably possess alternative understandings. In this study, 13 veiled American Muslim women share their experiences, and under the lens of standpoint theory, the participants' definition of hijab emerges. Specifically, the women inscribe hijab with meanings shaped by their unique cultural standpoints. Hijab functions to define Muslim identity, perform a behavior check, resist sexual objectification, afford more respect, preserve intimate relationships, and provide freedom.

Finding and explaining differences: A reply to Gudykunst and Hammer

A rejoinder to Gudykunst and Hammer's critique of a recent paper is presented. We argue that their position is based on two mutually exclusive propositions and cannot therefore be credible. We continue to maintain that the evidence on intercultural effectiveness shows both culture-general and culture-specific components.     

政治与伦理之间——清末政论报人媒介伦理观念的政治文化反思

在政治文化的规约下,媒介伦理规范的功利化、媒介伦理评价的政治化、媒介伦理内涵的人品化,成为清末政论报人媒介伦理观的基本特征。其问题,如媒介伦理本体价值的缺乏、媒介伦理建设上社会性资源的缺失,均可从政治文化层面得到独到的解释。     

“To Disdain the Truth and Look at Others with Contempt:” Byzantines and Muslims on Latin Pride and Arrogance,ca. 1100–1300

This essay examines the fundamentals of the Byzantine and Muslim political discourses during the period of the Crusades by analyzing a common political trope, the concept of Western pride and arrogance. The principal argument is that the seemingly stable categories of Eastern political propaganda obscure a massive discursive shift. At the beginning of their encounter with the Latin Christians both Byzantines’ and Levantine Muslims’ discourses on power and their place on the international stage were hegemonical, exclusive and self-referential. Towards the end of the Crusading period and under the steady pressures of Western practices, both societies’ political discourses came to accept as legitimate principles of international politics—such as power as a claim rather than a right, relations based on contract, territoriality and legitimacy of secular rule—that have long been the staple of Western conceptualization of politics, but were initially seen as utterly alien by Byzantines and Levantine Muslims.
