This article explores how “flatten the curve” (FTC) visualizations have served as a rhetorical anchor for communicating the risk of viral spread during the COVID-19 pandemic. Beginning from the premise that risk visualizations have eclipsed their original role as supplemental to public risk messaging and now function as an organizer of discourse, the authors highlight three rhetorical tensions (epideictic–deliberative, global–local, conceptual metaphors–data representations) with the goal of considering how the field of technical and professional communication might more strongly support visual risk literacy in future crises.
This study identifies communication design challenges associated with firefighters' personal protective equipment (PPE), an assemblage of wearable technologies that shield these workers from occupational hazards. Considering two components of modern firefighting PPE through Zuboff's (1998) theorization of information technology, we offer an extended case study that illustrates how these wearables, as interfaces,
automate
or
informate
firefighters' practice of safety. Often lauded for their abilities to augment firefighters' work capacities and increase safety outcomes, our analysis revealed that these wearables engender practices that expose firefighters to unforeseen hazards and displace the "tacit craft skills and knowledge" that these workers mobilize to mitigate workplace risk (Spinuzzi, 2005, p. 164). Drawing from these insights, we sketch four points of tension that communication designers, system architects, and practitioners may utilize to consider the informating potential of smart-firefighting PPE equipped with physiological sensors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
