  Title Media Prophylaxis: Night Modes and the Politics of Preventing Harm Type Journal Article
  Year 2018 Publication Information & Culture Abbreviated Journal Information & Culture  
  Volume 53 Issue 2 Pages 175-202  
  Keywords (up) History; Lighting; Society  
  Abstract This article develops the term “media prophylaxis” to analyze the ways technologies are applied to challenges of calibrating one’s body with its environment and as defenses against endemic, human-made harms. In recent years, self-illuminated screens (like those of computers, phones, and tablets) have been identified by scientists, journalists, and concerned individuals as particularly pernicious sources of sleep-disrupting light. By tracing the history of circadian research, the effects of light on sleep patterns, and the recent appearance of software like “f.lux,” Apple’s “Night Shift,” and “Twilight,” this article shows how media-prophylactic technologies can individualize responsibility for preventing harm while simultaneously surfacing otherwise ignored forms of chronic suffering.

  Title Electric Lighting Policy in the Federal Government, 1880-2016 Type Journal Article
  Year 2018 Publication Abbreviated Journal  
  Volume Issue Pages  
  Keywords (up) History; Policy; Lighting  
  Abstract Federal policies have targeted electric lighting since the 1880s with varying success. This dissertation examines the history of those policies to understand policy makers’ intent and how their decisions affected the course of events. This qualitative study poses three research questions: How have changes in lamp efficacy affected policy development? How and why have federal policies targeted electric lighting? How have private sector actors adapted public policy to further their own goals? The analysis uses an interdisciplinary approach taking advantage of overlapping methodologies drawn from policy and political sciences, economics, and the history of technology. The concepts of path dependency, context, and actor networks are especially important. Adoption of electric lighting spurred the construction of complex and capital intensive infrastructures now considered indispensable, and lighting always consumed a significant fraction of US electric power. Engineers and scientists created many lamps over the decades, in part to meet a growing demand for energy efficient products. Invention and diffusion of those lamps occurred amid changing standards and definitions of efficiency, shifting relations between network actors, and the development of path dependencies that constrained efforts to affect change. Federal actors typically used lighting policy to conserve resources, promote national security, or to symbolically emphasize the onset of a national crisis. The study shows that after an initial introductory phase, lighting-specific policies developed during two distinct periods. The earlier period consisted of intermittent, crisis-driven federal interventions of mixed success. The later period featured a sustained engagement between public and private sectors wherein incremental adjustments achieved policy goals. A time of transition occurred between the two main periods during which technical, economic, and political contexts changed, while several core social values remained constant. In both early and later periods, private sector actors used policy opportunities to further commercial goals, a practice that public sector actors in the later period used to promote policy acceptance. Recently enacted energy standards removing ordinary incandescent lamps in favor of high efficiency lamps mark the end of the later period. Apparent success means that policy makers should reconsider how they use lighting to achieve future goals.

  Title What is French about the “French fear of darkness”? The co-production of imagined communities of light and energy Type Journal Article
  Year 2019 Publication Journal of Energy History Revue d'Histoire de l'Energie Abbreviated Journal  
  Volume 2 Issue Pages  
  Keywords (up) History; Society; Energy; Lighting; France  
  Abstract This essay takes expert assumptions about light preferences as a starting point for a historical inquiry into what I call imagined sociotechnical communities of light and energy. My argument is that historical energy supply systems produced these imaginaries and vice versa, shifting the scales at which public lighting was envisioned and darkness was acceptable. While in the 17th C. dark streets were the norm and even the illumination of single streets was publically contested, innovators of the 18th C. imagined gas light and energy on an urban scale. In the 20th C., electric lighting promoted electrification and the electricity supply systems in countries like France allowed experts to think and standardize lighting at a national level. In the 21st C. the expert imaginary of a light-loving French people is challenged by public environmental concern.

  Title The effects of self-selected light-dark cycles and social constraints on human sleep and circadian timing: a modeling approach Type Journal Article
  Year 2017 Publication Scientific Reports Abbreviated Journal Sci Rep  
  Volume 7 Issue Pages 45158  
  Keywords (up) human health, lighting  
  Abstract Why do we go to sleep late and struggle to wake up on time? Historically, light-dark cycles were dictated by the solar day, but now humans can extend light exposure by switching on artificial lights. We use a mathematical model incorporating effects of light, circadian rhythmicity and sleep homeostasis to provide a quantitative theoretical framework to understand effects of modern patterns of light consumption on the human circadian system. The model shows that without artificial light humans wakeup at dawn. Artificial light delays circadian rhythmicity and preferred sleep timing and compromises synchronisation to the solar day when wake-times are not enforced. When wake-times are enforced by social constraints, such as work or school, artificial light induces a mismatch between sleep timing and circadian rhythmicity ('social jet-lag'). The model implies that developmental changes in sleep homeostasis and circadian amplitude make adolescents particularly sensitive to effects of light consumption. The model predicts that ameliorating social jet-lag is more effectively achieved by reducing evening light consumption than by delaying social constraints, particularly in individuals with slow circadian clocks or when imposed wake-times occur after sunrise. These theory-informed predictions may aid design of interventions to prevent and treat circadian rhythm-sleep disorders and social jet-lag.
