  Title Mapping the consequences of artificial light at night for intertidal ecosystems Type Journal Article
  Year 2019 Publication Science of The Total Environment Abbreviated Journal Science of The Total Environment  
  Volume 691 Issue Pages 760-768  
  Keywords Ecology; Lighting  
  Abstract Widespread coastal urbanization has resulted in artificial light pollution encroaching into intertidal habitats, which are highly valued by society for ecosystem services including coastal protection, climate regulation and recreation. While the impacts of artificial light at night in terrestrial and riparian ecosystems are increasingly well documented, those on organisms that reside in coastal intertidal habitats are less well explored. The distribution of artificial light at night from seaside promenade lighting was mapped across a sandy shore, and its consequences for macroinvertebrate community structure quantified accounting for other collinear environmental variables known to shape biodiversity in intertidal ecosystems (shore height, wave exposure and organic matter content). Macroinvertebrate community composition significantly changed along artificial light gradients. Greater numbers of species and total community biomass were observed with increasing illumination, a relationship that was more pronounced (increased effects size) with increasing organic matter availability. Individual taxa exhibited different relationships with artificial light illuminance; the abundances of 27% of non-rare taxa [including amphipods (Amphipoda), catworms (Nephtys spp.), and sand mason worms (Lanice conchilega)] decreased with increasing illumination, while 20% [including tellins (Tellinidae spp.), lugworms (Arenicola marina) and ragworms (Nereididae spp.)] increased. Possible causes of these relationships are discussed, including direct effects of artificial light on macroinvertebrate behaviour and indirect effects via trophic interactions. With increasing light pollution in coastal zones around the world, larger scale changes in intertidal ecosystems could be occurring.

  Title Analyzing the obstruction effects of obstacles on light pollution caused by street lighting system in Cambridge, Massachusetts Type Journal Article
  Year 2019 Publication Environment and Planning B: Urban Analytics and City Science Abbreviated Journal Environment and Planning B: Urban Analytics and City Science  
  Volume in press Issue Pages 2399808319861645  
  Keywords Skyglow; Lighting; upward light  
  Abstract Artificial light has transformed urban life, enhancing visibility, aesthetics, and increasing safety in public areas. However, too much unwanted artificial light leads to light pollution, which has a negative effect on public health and urban ecosystems, as well as on the aesthetic and cultural meanings of the night sky. Some of the factors interfering with the estimation of light pollution in cities are urban features, such as the presence of trees, road dimensions, and the physical characteristics of buildings. In this study, we proposed a simplified model for unwanted upward light coming from street luminaires based on a building height model and the publicly accessible Google Street View images. We simulated and analyzed the obstruction effects of different street features on the light pollution caused by the street lighting system in Cambridge, Massachusetts. By providing quantitative information about the connections between the streetscape features and the amount of unwanted upward artificial light, this study provides reference values to inform policies aimed at curbing light pollution.

  Title Half a century of Lighting Research & Technology: A bibliometric review Type Journal Article
  Year 2019 Publication Lighting Research & Technology Abbreviated Journal Lighting Research & Technology  
  Volume in press Issue Pages 1477153519857788  
  Keywords History; Lighting; Review  
  Abstract Lighting Research & Technology (LRT) is an influential journal in the field of light and lighting dating back to 1969. To celebrate its 50th birthday, the current study explored its bibliometric characteristics and mapped the bibliographic information graphically through VOSviewer software. This analysis found that the number of papers has steadily increased during recent years. The most productive and cited country was the United Kingdom. The most productive and cited institution was Rensselaer Polytechnic Institute. The most prolific author was Steve Fotios and the most cited author was Mark Rea. The journal most cited together with LRT was Leukos. LRT has become more and more international and interdisciplinary over the last five decades. Suggestions for the development of LRT are provided. Develpoments over the last 50 years have turned LRT into one of leading journals in the light and lighting field, one which has a bright future.

  Title Assessment of Light Pollution Based on the Analysis of Luminous Flux Distribution in Sports Facilities Type Journal Article
  Year 2019 Publication Engineer of the XXI Century Abbreviated Journal  
  Volume 70 Issue Pages 139-150  
  Keywords Lighting  
  Abstract The article attempts to assess the amount of light pollution with artificial light from sports facilities. The football stadium has been analysed, while considering a few configurations that take into account different coefficients of reflection of the luminous flux for the tribunes and the object main board. Simplified model of the football stadium was introduced to the DIALux simulation software, and then computer calculations were made for selected variants. In addition, the applicable normative requirements in the field of lighting systems were discussed and the mathematical distribution of the luminous flux in the examined sports facility was presented.

  Title Light affects heart rate's 24-h rhythmicity in intensive care unit patients: an observational study Type Journal Article
  Year 2019 Publication Nursing in Critical Care Abbreviated Journal Nurs Crit Care  
  Volume 24 Issue 5 Pages 320-325  
  Keywords Lighting; Human Health; Heart Rate; ICU; Circadian Rhythm  
  Abstract BACKGROUND: Intensive care unit (ICU) patients experience two affronts to normal 24-h rhythms: largely internal events such as medication and external factors such as light, noise and nursing interventions. AIMS AND OBJECTIVES: We investigated the impact of light variance within an ICU on 24-h rhythmicity of three key physiological parameters: heart rate (HR), mean arterial blood pressure (MAP) and body temperature (BT) in this patient population. DESIGN: Patients were assigned to beds either in the 'light' or 'dark' side within a single ICU. An actigraph continuously recorded light intensity for a 24-72-h period. METHODS: Measurements of HR, MAP and BT were recorded every 30 min. RESULTS: HR, MAP and BT did not follow 24-h rhythmicity in all patients. Higher light exposure in the Light Side of the ICU (122.3 versus 50.6 lx) was related to higher HR (89.4 versus 79.8 bpm), which may translate to clinically relevant outcomes in a larger sample. Duration of stay, the one clinical outcome measured in this study, showed no significant variation between the groups (p = 0.147). CONCLUSIONS: ICU patients are exposed to varying light intensities depending on bed positioning relative to natural sunlight, affecting the 24-h rhythm of HR. Larger, well-controlled studies also investigating the effect of relevant light intensity are indicated. RELEVANCE TO CLINICAL PRACTICE: Light is a variable that can be manipulated in the constrained environment of an ICU, thus offering an avenue for relatively unobtrusive interventions.
