This article details study results comparing e-mail and synchronous conferencing as vehicles for online peer response. The study draws on Clark and Brennan's theory of communicative “grounding,” which predicts that participants use different techniques for achieving mutual knowledge depending on the type of media being used. Content analysis of transcripts from both types of response sessions showed that when using e-mail, students made significantly greater reference to documents, their contents, and rhetorical contexts than when using synchronous conferencing. Students made greater reference to both writing and response tasks using synchronous chats than when using e-mail. Students' individual media preferences showed no significant differences in terms of message formulation, reception, and usefulness of comments in aiding revision. However, in a forced comparison scale, students rated e-mail more serious and helpful than chats, which were then rated more playful than e-mail. Implications of the study's results and areas for future research are also discussed.

This study investigates how sustainability and its inherent values figure into farmers' discourse, i.e., how farmers and members of farming communities talk about sustainability. We conducted qualitative interviews of various individuals in a single Iowa community to determine whether the visions guiding their land management choices resembled at all the ideals of a sustainable agriculture. Using Kenneth Burke's concepts of identification and division, we rhetorically analyzed the interview transcripts. We found animosity towards much green terminology but widespread commitment to environmental preservation, especially when aligned with economic interests. We highlight rhetorical strategies for promoting sustainable practices.

This article provides a cultural-historical analysis of dictation as a composing method in Western history. Drawing on Ong’s concept of secondary orality, the analysis shows how dictation’s shifting role as a form of literacy has been influenced by the dual mediation of technological tools and existing cultural practices. At the dawn of modernism, a series of technological, economic, and philosophical factors converged to promote silent forms of individual authorship over collaborative modes of dictation favored in late antiquity and the Middle Ages. Similar changes are taking place today and may help reverse the dominance of silent authorship. If voice-recognition technologies continue to improve in the future, they may help professional communicators bridge the spoken and textual realms and effect changes in our attitudes toward authorship and orality.
