Visualizing a Drug Abuse Epidemic: Media Coverage, Opioids, and the Racialized Construction of Public Health Frameworks

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.

To Paint and Die in Arabic: Code-Switching in Rabih Alameddine's Koolaids: The Art of War

I focus on multilingual usages, specifically code-switching between English and Arabic, in Lebanese American Rabih Alameddine's 1998 novel Koolaids: The Art of War. While the novel portrays English as the emancipatory language of coming out and self-acceptance for gay Lebanese men living in the United States between the late 1970s and mid-1990s, Mohammad, a painter, only comes to terms with his impending demise by reverting to Arabic during the final stages of his losing battle with AIDS. Drawing on findings from psycholinguistic, sociolinguistic, translation, and medical/neurological studies, I compare and contrast verbal encounters between Mohammad and various Lebanese and American characters to foreground strategies intended to exclude and/or include certain parties, be they characters or readers. While Arabic words actually employed are few, I argue that implied code-switching and the dynamics of speaker(s), interlocutor(s), setting(s), and context(s) establish links among AIDS, Arabic, art, and acceptance of death; Arabic resurfaces, when Mohammad is on his deathbed, as the language of his childhood and even serves as the bridge toward his “afterlife.” The primary theoretical impacts of my reading are twofold: minimal code-switching does not, as some claim, showcase shallow multilingualism, and a language-minded approach adds a new dimension to the definition of Lebanese (Arab) American literature by focusing on the emotional rather than the national/ethnic facets of the embedded native language.

Optimising meritocratic advantage with the International Baccalaureate Diploma in Australian schools

This paper explores two of the tensions Tarc identifies in the history of the International Baccalaureate (IB) Diploma: firstly, between its design for meritocratic competition and its internationalist vision and, secondly, between the IB as a global commodity and its localised interpretations. Using data from three case studies of Australian schools offering both the IB Diploma and the local government curriculum, and student responses to an online survey across 26 such schools, the analysis shows how choices behind the IB's growing popularity foreground strategies for optimising meritocratic competition. Framed through Bourdieu's concepts of field and ‘rules of the game’, the analysis shows how students act on their own comparative analyses of each curriculum to optimise their chances to access desirable university pathways within the local rules of the game for university placement. Schools are shown to offer the IB Diploma to recruit and retain academically ambitious students by pooling their relative advantage in different local ecologies. Students are shown to carefully evaluate the benefits and costs of the IB choice. The conclusion reflects on how the choice of the IB Diploma for meritocratic advantage by some might change conditions for others not choosing it.

Noise effects and filtering in controlled light exposure microscopy

Phototoxicity and photobleaching are major limitations of fluorescence live-cell microscopy. A straightforward way to limit phototoxicity and photobleaching is reduction of the excitation light dose, but this causes loss of image quality. In confocal fluorescence microscopy, the field of view is illuminated uniformly whereas in controlled light exposure microscopy, illumination is controlled per pixel on the basis of two illumination strategies. The controlled light exposure microscopy foreground strategy discriminates between bright and weak foreground. Bright foreground pixels are illuminated with a reduced light dose resulting in limited excitation of fluorophores and consequently limited phototoxicity and photobleaching. The controlled light exposure microscopy background strategy discriminates between foreground and background. Pixels that are judged to be background are also illuminated with a reduced light dose. The latter illumination strategy may introduce artefacts due to the stochastic character of photon flow. These artefacts are visible as erratic 'darker pixels' in the foreground with a lower pixel value than the neighbouring pixels. This paper describes a special adaptive image processing filter that detects and corrects most of the 'darker pixels'. It opens the possibility to use controlled light exposure microscopy even in high noise (low signal to noise ratio) imaging to further reduce phototoxicity and photobleaching.
