Technical and professional communication (TPC) scholars are increasingly critical of the complex relations between surveillance, power, and technologies, particularly how those relations reinforce ...

This article examines how digital contact tracing technologies for COVID-19 in Ghana, the US, China, and India function as persuasive technologies. Through comparative analysis, we investigate how each context emphasizes persuasive design strategies and how these align with national public health objectives. We propose an extended Common Interpretive Framework for Design Analysis (eCIFDA), which integrates Persuasive Systems Design with Interaction Design to map persuasive techniques to touchpoints within apps and a website. This study offers insights for technical communication scholars and practitioners seeking to strengthen the persuasive effectiveness of digital health interventions across diverse geopolitical contexts.

Although the field of illustration is a major topic in technical and professional communication (TPC), social justice regarding medical illustrations is yet to be investigated. Drawing from an analysis of TPC journals, program websites, textbooks, and syllabi, this study explores how TPC could advance a social justice view on medical illustration, especially in the textbooks that we use in teaching medical and science writing courses. Not only did we find that very few medical and science writing textbooks included illustrations, but a significant number of illustrations were white. We suggest intentionality in the choice of pedagogical materials, overt discussion of social justice in the curriculum, and critical borrowing of pedagogical materials.

Background: Technologies are increasingly being deployed in facilitating participatory healthcare. Global governments developed a variety of digital platforms, such as mobile contact tracing apps, to help the public navigate risks and uncertainties during the COVID-19 pandemic. Literature review: Contrary to normative approaches to information design (IxD), the global spread of COVID-19 revealed the need for an alternative design framework (i.e., concept-driven design) to help develop mobile health (mHealth) apps that can support a broader portrayal of information value in IxD. Research questions: 1. In response to COVID-19, what affordances are prioritized by the designers of these global mHealth apps? What do these priorities tell us about design intents and information value? 2. What interpretive framework can we use to understand mHealth designers’ intent across different geopolitical contexts? Research methodology: We captured screenshots of the three apps in the US, India, and China, as well as a website in Ghana. Using touchpoints as the unit of analysis, we conducted an inventory and affinity mapping to visualize the architecture of each app and categorize touchpoints based on their affordances. Results: The comparison of apps across countries displays shared and divergent priorities in their touchpoints, affordances, and information depth. We developed an interpretive framework for understanding mHealth design intent across numerous contexts—Common Interpretive Framework for Design Analysis (CIFDA)—incorporating both linear analysis and recursive analysis of touchpoints, affordances, and depth. Conclusions: Touchpoints in mHealth applications can be designed, but they can also be measured and analyzed, and they can in return help us understand the designer's intent and expected user experience.

I propose Multimodal Critical Discourse Analysis (MCDA) as an approach for understanding the discursive and material implications of technical documents in distant sites. I provide a historical vignette of MCDA and exemplify how technical and professional communication (TPC) researchers can critically engage with distant sites through MCDA by analyzing materials about GhanaPostGPS, a geolocation technology. I conclude by discussing limitations of MCDA – access to archives – and propose the creation of crowdsourced technical documentation archives.
