In this article, the author theorizes the process that a World Health Organization work group used to update yellow fever risk maps published in the Yellow Book, a handbook created by the Centers for Disease Control and Prevention for international travelers, from a “wicked problems” perspective. She argues that using this model highlights the complexity of nonexperts’ risk assessment practices in this context and that the work group's decision to create vaccination maps demonstrates an increased awareness of the embodied decision-making practices that nonexperts perform, aligning with and contributing to the growing emphasis on creating user-centered risk information that can be seen in some risk communication.

In technical and professional communication, the social justice turn calls on us to interrogate sites of positionality, privilege, and power to help foreground strategies that can empower marginalized groups. I propose that mainstream media coverage of the opioid epidemic represents such a site because addiction to these drugs, which initially primarily affected White people, has been positioned as a public health issue rather than a criminal justice problem. I explore the strategies that were used to create this positioning by investigating themes in the visual rhetoric as conveyed through data visualizations and in the text of the articles in which these graphics were published. My results align with two previous studies that confirmed this public health framing. I also observed an emphasis on mortality, which contributes to our understanding of rhetorical strategies that can be used to engender support rather than condemnation for those suffering from drug addiction.

What are the rhetorical strategies used in data visualizations published during the crack and opioid drug epidemics, respectively? 2. Do these strategies advance dominant media narratives that crack addiction should be criminalized but opioid addiction should be treated like a public health issue? And if so, how is this accomplished? <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Methodology:</b> Drawing from the media studies approach previously employed in a study in technical and professional communication (TPC) on information design trends, I apply the concept of “scripto-visual” rhetoric to select data visualizations published by mainstream news media during both drug epidemics. <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Results:</b> I argue these graphics escalated the perceived threat during both drug epidemics but different scripto-visual rhetorical strategies were used. <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Conclusions:</b> Attending to ethical considerations in the creation of data visualizations has long been important in TPC, while scholarship has integrated social justice as a core component of the discipline. In the last section of this article, I bring these themes together by arguing that a social justice ethic is needed in data design work. I then propose a critical heuristic constructed from Jones et al.’s positionality, privilege, and power framework that can be used analytically or as an inventional tool to tease out the ways particular scripto-visual rhetorical decisions may be promoting inequities.

In this teaching experience report, we describe a research experience for undergraduates (REUs) designed to cognitively support the work of two student research assistants (RAs) from a two-year college (2YC) on a funded project that involved analyzing user-generated content for an mHealth app. First, we suggest partnerships between two- and four-year institutions as a move toward REU equity because students from 2YCs are not typically afforded these opportunities. We then review the role of research in undergraduate learning and posit the importance of scaffolding to sequence cognitive leaps. Finally, we present the cognitive scaffolding we created and connect it to our hybrid card sorting-affinity diagramming content analysis method.

We argue that by using existing data and sharing research in a databank, RHM scholars can practice a research habit that conserves and optimizes intellectual and institutional resources. When possible, by using existing datasets, scholars avoid data waste, that is ignoring or bypassing existing data. The data distinctions that we call attention to—derived, compiled, and designed—account for various ethical and rhetorical concerns regarding privacy and confidentiality, expected context, and consent. Equally important to the aforementioned data deliberations we explore, collecting and managing shared RHM data in a databank, while possible, are not without ethical, logistical, and rhetorical difficulties.

This article proposes a heuristic that teachers and students can use together to create a vocabulary for discussing the aesthetic aspects of color and typography in document design work. By using this framework, teachers and students can generate a collection of shared visual topoi or commonplaces for describing the aesthetic value of color and typography that they can then draw from to inform visual analysis and production work.

As fitness trackers have proliferated, many now collect information about both physical and mental health indicators. Arguably, such capabilities promote the notion that achieving and maintaining health is holistic, pushing back against the mind/body divide that has long characterized how we tend to perceive health and disease in Western cultures (see Segal, 2005). In this article, the author argues that the visual (photographs and data visualizations) and language-based communication strategies used on Bellabeat Leaf's website, a smart jewelry device for women, employ a narrative of holisticism. Further, this narrative functions as a rhetorical trope that reinforces power relationships that align with a dominant underlying ideology of Western medicine---the notion that disease and illness can be controlled. The author proposes that future designs of the Leaf's smartphone application might allow users to visualize quantitative and select user-contributed qualitative, sensorial-based feedback to potentially provide a more balanced perspective of health.

Health literacy is an embodied, multisensory experience that is invariably mediated by healthcare technologies. We illustrate this concept through three case studies that describe scenarios in which non-experts and lay experts engage in non-discursive literacy practices: parents caring for an infant in a neonatal intensive care unit (NICU), people with type 1 diabetes (T1D) self-managing their treatment, and public audiences reporting symptoms to a crowd-sourced flu-tracking program.

In this article, the author proposes that the emergence of digital, disease-tracking applications over the past ten years like HealthMap (healthmap.org) and Flu Near You (flunearyou.org) that allow non-experts to contribute information about emergent public health threats have facilitated a "do-it-yourself (DIY)" risk assessment ethic. Focusing in particular on Flu Near You (FNY), a crowdsourced, flu-tracking program, the author argues that some participants use the mapping feature to curate their own risk information experience in determining the preventative behaviors they may want to engage in (if any) to prevent flu. As outbreaks of infectious diseases increase (Smith et al., 2014), mHealth technologies like disease-tracking apps are evolving as an important risk assessment tool for both public health experts as well as non-expert, public audiences. Better understanding how non-experts use such information can inform not only the design of these apps but visual risk communication strategies more generally speaking.

Medical cartography became an important data visualization tool in the 19th century. In this article, the author argues that early yellow fever maps invoked power and authority over diseased space through their visual conventions and scientific authority as statistical graphics as well as by visually reinforcing underlying Western ideologies about disease, illness, and health. Further, the creation of these maps established a visual precedent for invoking this authority that continues today. As public health continues to move toward a global health perspective in the 21st century, understanding how mapping constructs and shapes knowledge about disease, illness, and health will become increasingly important.

Last semester I gave a talk to a small group of graduate students and faculty in the Department of Animal and Food Sciences in the College of Agriculture on my campus. As one of several invited speakers for the department's graduate seminar series, the purpose, I was told, was straightforward: model an effective presentation for the students. I teach courses in technical and professional communication so I imagined it might also be useful to discuss presentation strategies. I concluded by giving an overview of my own research interests---broadly, visual communication---and briefly described a project I am working on related to scientific graphics and historic public health maps.
