Our article uses case studies of two civilian emergency response mHealth apps—PulsePoint and OD Help—to theorize the ways the mobile mapping functionality embedded in these tools, which is integrated with the Google Maps platform, enables yet also constrains users’ agential practices. Using an interface rhetoric approach, we unpack assumptions related to the embodied contexts of use facilitated by this functionality within the unique scenario of civilian emergency response. We argue that interactions between and among humans and these apps’ mapping interfaces involve complex, negotiated, contextually situated enactments, which align with a posthumanist perspective toward agency. At the same time, these interactions may also inadvertently amplify the precarity of vulnerable groups. Better understanding the ways that mobile mapping technologies shape agential enactments, particularly in ways that affect precarious and dispossessed populations, has important implications for the design of mHealth technologies—and the users who rely on them—moving forward.

Building connections with professionals in subject matter disciplines—practitioners and/or academics—is a growing area of interest for many scholars working in the rhetoric of health and medicine (RHM). However, strategies for creating and building meaningful, productive interdisciplinary relationships has not been a central theme in RHM-focused scholarship. This entry endeavors to address this gap by using RHM’s emerging version of the “dialogue” genre to describe the author’s experience co-chairing the communications track for an international public health conference. The author weaves in commentary from contributors who participated in the conference and discusses and reflects upon two key challenges that emerged: 1) differences in language choice/terminology, and 2) epistemic conflict. Through this reflective discussion, this dialogue proposes several strategies that RHM scholars might draw from in building their own interdisciplinary relationships moving forward: 1) negotiate shared meanings and goals, 2) find commonalities, and 3) normalize rhetorical inquiry.
