Amidst the panic, fear, and uncertainty during the COVID-19 pandemic, Dr. Wenhong Zhang emerges as a go-to source for the Chinese public to seek information to protect themselves and find hope and order in their distress. Focusing on Dr. Zhang's 39 WeChat posts from January 2020 to March 2022, this case study reveals that he employs a constructed ethos and leverages WeChat as a powerful social media to craft the kairotic responses to the pandemic.

Black mentorship is key to the professional development of Black scholars in technical and professional communication (TPC) and writing studies. Blending narrative ethnography and grounded theory, this article extends existing investigations into mentorship among Black professionals, by exploring how mentorship and rhetorical kinship among Black TPC and writing professors enrich their professional development. With implications for both academia and industry, this article highlights how Black TPC scholars develop, negotiate, and sustain Black professional ethos.

This article examines how nonprofessionals in early modern England used tactical technical communication and rhetorical strategies to build medical knowledge and healthcare expertise. Using a feminist ethos and tactical technical communication lens, this article details a content analysis study of 4,045 handwritten medical recipes from England dated between 1540 and 1860. Findings from the study extend tactical technical communication by examining non-digital/non-internet spaces and how extra-institutional nonprofessionals build ethos and expertise.

The expanding use of social media such as Twitter has raised the stakes for teaching our students about individual and organizational ethoi. This article considers the role of organizations' Twitter feeds during emergency situations, particularly Hurricane Irene in 2011, to argue for a pedagogical model for helping students collaboratively code tweets to assess their rhetorical effects and to improve their own awareness and use of microblogging as a communication tool.

This article develops a multimodal model for how claims and evidence work across linguistic, numeric, and visual modes in the professional writing of environmental scientists. I coded and analyzed two reports (Bacey & Barry, 2008 Bacey , J. , & Barry , T. ( 2008 ). A comparison study of the proper use of Hester-Dendy® samplers to achieve maximum diversity and population size of benthic macroinvertebrates Sacramento Valley, California (Report No. EH08-2) . Sarcramento , CA : California Environmental Protection Agency . [Google Scholar]; Levine et al., 2005 Levine , J. , Kim , D. , Goh , K. S. , Ganapathy , C. , Hsu , J. , Feng , H. , & Lee , P. ( 2005 ). Surface and ground water monitoring of pesticides used in the Red Imported Fire Ant Control Program (Report EH05-02) . Sacramento , CA : California Environmental Protection Agency . [Google Scholar]) written by research scientists working for California's Department of Pesticide Regulation (DPR) by applying concepts from studies of argument, genre, and visual representations in science. The claim-evidence patterns show initial and summative claims as well as warrants being presented in linguistic forms; however, supporting evidence (i.e., data and backing) is found in numeric, visual, and linguistic forms. These findings highlight the need to extend Toulmin's understanding of claim-evidence relationships into a more robust multimodal model.

This article reports my classroom-based qualitative research, conducted at a midwestern university, on the role of World Englishes in the ethos transformation of U.S. native English-speaking students. The 30 participants completed assignments that enhanced their understanding of how the English language affects discursive tasks in international audience adaptation. Efforts at internationalizing technical communication can benefit immensely from the inclusion of the World Englishes paradigm in training programs to account for students' language attitudes.

“The study of activity ceases to be the psychology of an individual, but instead focuses on the interaction between an individual, systems of artifacts, and other individuals in historically developing institutional settings” (Miettinen, 1997). As teaching technical writing online becomes more widespread, teachers and scholars are identifying ways to increase teaching/learning efficacy. One way of accomplishing this goal is by continually reflecting on different types of student ethos being constructed in an online course. The changes that occur in the ethos development process can be contextualized through activity theory, which emphasizes the dynamic, evolving nature of social environments. Activity theory's focus on cultural history and tools makes it ideal for exploring active communication among multiple participants in an online technical communication environment. The triangle of human activity adapted and developed by Engeström (1987) Engeström, Y. 1987. Learning by expanding: An activity theoretical approach to developmental research., Helsinki, Finland: Orienta-Konsultit Oy. [Google Scholar] provides a framework for exploring ethos as an object within an online course's activity system.

Drawing on the rhetorical concept of ethos, this study explores the professional identities, health-care relationships, and forms of community constructed by two midwifery websites in Ontario. Rather than facilitating communal and dialogic modes of communication with the public, these websites enact primarily a unidirectional consumption model. This design structure both reflects and reinforces the complexities of midwifery's recent shift from being an explicitly alternative form of health care, to becoming part of the dominant health-care framework.

Analogical reasoning has long been an important tool in the production of scientific knowledge, yet many scientists remain hesitant to fully endorse (or even admit) its use. As the teachers of scientific and technical writers, we have an opportunity and responsibility to teach them to use analogy without their writing becoming “overly inductive,” as Aristotle warned. To that end, I here offer an analysis of an example of the effective use of analogy in Rodney Brooks's “Intelligence Without Representation.” In this article, Brooks provides a model for incorporating these tools into an argument by building four of them into an enthymeme that clearly organizes his argument. This combination of inductive and deductive reasoning helped the article become a very influential piece of scholarship in artificial intelligence research, and it can help our students learn to use analogy in their own writing. Every one who effects persuasion through proof does in fact use either enthymemes or examples: there is no other way. (Aristotle, 1984b Aristotle. 1984b.
