Title More-than-human media architecture Type Journal Article
Year 2018 Publication Abbreviated Journal
Volume (up) Issue Pages
Keywords Architecture; Lighting; Planning
Abstract We consider some of the planetary conditions and global circumstances that both research and practice of media architecture are embedded within, such as climate change, pollution, resource consumption, and loss of biodiversity. While there has been a notable increase in emphasis on participation and engagement in design and use, with the aim to increase the involvement of diverse and often marginalised citizens, a human-centred approach to media architecture comes with its own set of problems. In this paper, we want to draw the attention of the media architecture community to the fallacy of human exceptionalism and anthropocentrism. We present a critical review of examples of media architecture projects and installations that question our understanding of urban space as separate from nature, and designed primarily for humans and just humans. Informed by studies in disciplines such as science and technology studies, critical geography, urban planning, and interaction design, we use insights derived from our review to discuss ways towards a more-than-human approach to media architecture. We conclude by proposing for discussion nascent design considerations for media architecture to go beyond the needs of just humans and to consider new ways to appreciate and cater for our broader ecological entanglements with plants, animals, and the environment at large.

Title Re-envisioning the Nocturnal Sublime: On the Ethics and Aesthetics of Nighttime Lighting Type Journal Article
Year 2018 Publication Topoi Abbreviated Journal
Volume (up) In press Issue Pages
Keywords Society
Abstract Grounded in the practical problem of light pollution, this paper examines the aesthetic dimensions of urban and natural darkness, and its impact on how we perceive and evaluate nighttime lighting. It is argued that competing notions of the sublime, manifested through artificial illumination and the natural night sky respectively, reinforce a geographical dualism between cities and wilderness. To challenge this spatial differentiation, recent work in urban-focused environmental ethics, as well as environmental aesthetics, are utilized to envision the moral and aesthetic possibilities of a new urban nocturnal sublime. Through articulating the aspirations and constraints of a new urban nocturnal experience, this paper elucidates the axiological dimensions of light pollution, draws attention to nightscapes as a site of importance for urban-focused (environmental) philosophy, and examines the enduring relevance of the sublime for both the design of nighttime illumination and the appreciation of the night sky.

Title Street Lighting and Public Safety: New Nighttime Lighting Documentation Method Type Journal Article
Year 2018 Publication ARCC Conference Repository Abbreviated Journal
Volume (up) Issue Pages
Keywords Public Safety; Lighting
Abstract While the rapid transition of street lighting technologies is occurring across the country for its promising benefits of high energy efficiency, higher intensity, long lamp life, and low maintenance, there is a lack of understanding on the impacts from street lighting’s physical characteristics on public safety. Nighttime lighting and its impact on the incidence of crime and roadway accidents has been investigated since the 1960s in the United States and the United Kingdom. However, prior research has not presented any scientific evidence such as quantified lighting characteristic data and its impacts on public safety because they relied on subjective survey inputs or over-simplified quantification of nighttime lighting conditions. To overcome the limitation of previous studies, extensive documentation of street lighting characteristics was conducted in downtown San Antonio, Texas, which adopts both conventional and new street lighting technologies. Two different sets of light level data were collected on roadways in order to measure the amount of light falling on the ground and on drivers’ eyes inside a car. Correlated color temperature and a color rendering index of nighttime lighting were recorded. The collected lighting data was mapped in a Geographic Information Systems database in order to spatially analyze lighting characteristics. The paper first highlights the potential issues with lighting analysis in previous studies. Next, the proposed research methodology to address these issues for both data collection and spatial analyses is explained. Finally, the preliminary documentation and analysis of street lighting characteristics are presented.

Title Light intensity and suppression of nocturnal plasma melatonin in Arctic charr (Salvelinus alpinus) Type Journal Article
Year 2018 Publication Comparative Biochemistry and Physiology. Part A, Molecular & Integrative Physiology Abbreviated Journal Comp Biochem Physiol A Mol Integr Physiol
Volume (up) in press Issue Pages
Keywords Animals
Abstract The problem of early sexual maturation among farmed Arctic charr and other salmonids can be effectively reduced by 24h light overwinter, provided it is bright enough to over-ride interference from the natural daylength cycle. To determine the threshold light intensity to suppress the nocturnal elevation of plasma melatonin, three groups of individually tagged fish (n=26-28/group ca. 1040g) were reared on 12h light: 12h dark (LD 12:12) and subjected to nighttime light intensities of either 50-65, 0.1-0.3 or 0 (control) lux for five months (November to April). Daytime light intensity was 720-750lx. Diel plasma melatonin profiles in both November and April were similar; mean daytime levels ranged from 20 to 100pg/ml, and nighttime levels were inversely proportional to light intensity. In the control group at 0lx, plasma melatonin increased about four-fold after lights-off, ranging between 320 and 430pg/ml. Nighttime light intensity of 0.1-0.3lx halved plasma melatonin levels to 140-220pg/ml, and 50-65lx further reduced the levels to one quarter of the control group, 68-108pg/ml. Among the lit groups, daytime plasma melatonin levels were about 20-30pg/ml, significantly lower than the nocturnal levels suggesting the diel hormonal rhythm was not completely abolished. Fish grew steadily from about 1100g to 1600g between November and April, independent of light intensity (P=.67). Overall, the study demonstrated the sensitivity of pineal melatonin hormone to different light intensities in Arctic charr.

Title Artificial Lighting at Night in Estuaries—Implications from Individuals to Ecosystems Type Journal Article
Year 2018 Publication Estuaries and Coasts Abbreviated Journal
Volume (up) In press Issue Pages
Keywords Animals; Ecology
Abstract Artificial lighting at night (ALAN) produced by urban, industrial, and roadway lighting, as well as other sources, has dramatically increased in recent decades, especially in coastal environments that support dense human populations. Artificial “lightscapes” are characterized by distinct spatial, temporal, and spectral patterns that can alter natural patterns of light and dark with consequences across levels of biological organization. At the individual level, ALAN can elicit a suite of physiological and behavioral responses associated with light-mediated processes such as diel activity patterns and predator-prey interactions. ALAN has also been shown to modify community composition and trophic structure, with implications for ecosystem-level processes including primary productivity, nutrient cycling, and the energetic linkages between aquatic and terrestrial systems. Here, we review the state of the science relative to the impacts of ALAN on estuaries, which is an important step in assessing the long-term sustainability of coastal regions. We first consider how multiple properties of ALAN (e.g., intensity and spectral content) influence the interaction between physiology and behavior of individual estuarine biota (drawing from studies on invertebrates, fishes, and birds). Second, we link individual- to community- and ecosystem-level responses, with a focus on the impacts of ALAN on food webs and implications for estuarine ecosystem functions. Coastal aquatic communities and ecosystems have been identified as a key priority for ALAN research, and a cohesive research framework will be critical for understanding and mitigating ecological consequences.
