  Title Optimization of Urban Street Lighting Conditions Focusing On Energy Saving, Safety and Users’ Needs Type Journal Article
  Year 2018 Publication (up) Contemporary Urban Affairs Abbreviated Journal  
  Volume 2 Issue 3 Pages 112-121  
  Keywords Lighting; Economics; Planning  
  Abstract The outdoor lighting constitutes a significant part of the night activities of people in contemporary cities. Nevertheless, in many cases, this may result in the increasing and irrational use of it affecting the users of public areas, the environment and driving safety. The subject of this paper is to extend the discussion on the subject, to provide answers and to suggest methods for the improvement of the existing conditions in urban street lighting through the use of new technologies and smart lighting management systems, with the aim of achieving a smooth relationship between the user’s needs, safety, sustainability, quality of life and energy saving.

  Title Bright environmental light improves the sleepiness of nightshift ICU nurses Type Journal Article
  Year 2018 Publication (up) Critical Care (London, England) Abbreviated Journal Crit Care  
  Volume 22 Issue 1 Pages 295  
  Keywords Circadian; Light; Night shift; Nurse; Shift work sleep disorder  
  Abstract BACKGROUND: Shift work can disturb circadian homeostasis and result in fatigue, excessive sleepiness, and reduced quality of life. Light therapy has been shown to impart positive effects in night shift workers. We sought to determine whether or not prolonged exposure to bright light during a night shift reduces sleepiness and enhances psychomotor performance among ICU nurses.

METHODS: This is a single-center randomized, crossover clinical trial at a surgical trauma ICU. ICU nurses working a night shift were exposed to a 10-h period of high illuminance (1500-2000 lx) white light compared to standard ambient fluorescent lighting of the hospital. They then completed the Stanford Sleepiness Scale and the Psychomotor Vigilance Test. The primary and secondary endpoints were analyzed using the paired t test. A p value <0.05 was considered significant.

RESULTS: A total of 43 matched pairs completed both lighting exposures and were analyzed. When exposed to high illuminance lighting subjects experienced reduced sleepiness scores on the Stanford Sleepiness Scale than when exposed to standard hospital lighting: mean (sem) 2.6 (0.2) vs. 3.0 (0.2), p = 0.03. However, they committed more psychomotor errors: 2.3 (0.2) vs. 1.7 (0.2), p = 0.03.

CONCLUSIONS: A bright lighting environment for ICU nurses working the night shift reduces sleepiness but increases the number of psychomotor errors.

  Title Shot in the Dark: Nocturnal Philosophy and Night Photography Type Book Chapter
  Year 2018 Publication (up) Critical Distance in Documentary Media Abbreviated Journal  
  Volume Issue Pages 45-67  
  Keywords Society; Art  
  Abstract This chapter examines the neglected practice of night photography, and how it critically addresses the environmental, sociohistorical, and urban issues in recent series by Christina Seely, Bruno Lessard, Michel Huneault, and Jeanine Michna-Bales. Drawing on Jacques Derrida, Emmanuel Levinas, and the emerging field of night studies to create a nocturnal philosophy—a dark photology—with which to frame the multifaceted issues at the heart of the series, the author examines the value that these photographic artists place upon night to document light pollution around the world, ongoing urban transformations in China, an environmental catastrophe and its aftermath in Québec, and the landscape of the Underground Railroad in the United States. These four series demonstrate how night photography offers a unique critical perspective on some of the most pressing problems of our age, and how these artists distance themselves from the predominantly diurnal register of documentary media.

  Title Field evaluation of light-emitting diodes to trap the cotton bollworm, Helicoverpa armigera Type Journal Article
  Year 2020 Publication (up) Crop Protection Abbreviated Journal Crop Protection  
  Volume in press Issue Pages  
  Keywords Animals  
  Abstract The cotton bollworm, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae), is a limiting pest of many agricultural crops worldwide. At present, in-field populations of H. armigera are routinely monitored using conventional light traps. During 2014, 2015, we conducted field assays to assess the relative attractiveness of narrow-band light-emitting diodes (LEDs) at 19 single wavelengths (375–748 nm) in H. armigera light traps. Between 2016 and 2019, LEDs with the most attractive wavelengths were then further evaluated in two different sites, i.e., Xinxiang and Anci (China). During 2014–2015, the highest H. armigera trap capture was obtained with LEDs at 395 nm, while it was not significantly different from LED wavelengths of 375 nm and 418 nm in 2015. During field trials in Xinxiang, H. armigera trap capture did not differ among (four) wavelengths (375 nm, 385 nm, 395 nm, and 405 nm) in either year. In the Anci site, most H. armigera adults were caught in traps equipped with LEDs of 385 nm during two years, but it was not significantly different from those at 405 nm in 2017. In 2019, H. armigera trap capture rate was higher for LEDs at 385 nm than for those at 395 nm, and 2.91-fold higher to that of a commercial UV blacklight (365 ± 50 nm) trap. Our work shows how LED-equipped traps constitute an efficient, energy-conserving way to monitor cotton bollworm populations, providing trap capture rates that surpass those of conventional technologies. We discuss how these innovative measures can complement the integrated pest management (IPM) toolbox for H. armigera in China and abroad.

  Title Reproductive Response of Soybeans to Night Interruption1 Type Journal Article
  Year 1981 Publication (up) Crop Science Abbreviated Journal  
  Volume 21 Issue 5 Pages 755  
  Keywords Plants  
  Abstract Artificial lights may be used to delay flowering of soybean [Glycine max (L.) Merr.] cultivars. Previous research has suggested that night interruption imposed every other night would delay flowering as much as every-night interruption. Our objective was to evaluate the reproductive development of cultivars when exposed to night interruption every night compared with exposure every other night. One cultivar of each Maturity Group 00 through V was grown in the field at Ames, Iowa during 1978 and 1979. The four light treatments imposed every night or every other night included illumination with incandescent light from sunset to sunrise, 2300 to 0030 hours, 0030 to 0200 hours, or 0200 to 0330 hours. Control plots were not exposed to artificial light.

The average number of days that reproductive development was delayed beyond the control was twice as great for the every-night treatments as for the every-other-night treatments. Illumination from sunset to sunrise delayed reproductive development significantly more than the treatments of night interruption for 1.5 hours. Night interruption near the end of the dark period (0200 to 0330 hours) delayed reproductive development more than the earlier interruptions.

The results did not support the hypothesis that light treatments every other night would delay reproductive development as much as every-night interruptions. The lighting regime needed to delay reproductive development will depend on the photoperiod requirements of the cultivars and duration of the delay that is desired.
