  Title Light Pollution And Immunosuppression: Determining The Role Of Artificial Lighting In Coccidiosis In Non-Migratory Birds Type Journal Article
  Year 2019 Publication The Bluebird Abbreviated Journal  
  Volume 86 Issue 3 Pages 131 - 140  
  Keywords Animals  
  Abstract Light pollution is a result of artificial light at night (ALAN), which inhibits many natural cycles of living organisms. Birds and other animals, including humans, are affected through hormonal discrep- ancies and circadian disruption. However, the effects of light pollu- tion on an animal’s immune response to pathogens have not been adequately investigated.

For this study non-migratory birds were chosen to determine the impact of light pollution within a certain area--urban, suburban, and rural. Fecal samples were taken from non-migratory bird spe- cies in areas that were classified based on sky quality meter read- ings measured in magnitude/arc second2. All fecal samples were an- alyzed for the presence of coccidia, a parasite usually found in avian species. A correlation was then made between the number of coccidia-infected individuals and the nocturnal light intensity at each location.

Results demonstrated that non-migratory birds were significantly (p < 0.05) more susceptible to contracting coccidiosis when exposed to a greater intensity of light pollution. This supports the hypothesis that light pollution causes negative ecological and economic impacts by disrupting natural cycles and instigating immunosuppression. This could potentially result in lower product yield and an increase in the need for pharmaceuticals for poultry farmers because the ALAN used at farms throughout the duration of the night may cause infection and inhibition of natural cycles of poultry.

  Title Nighttime Lights As A Quantitative Indicator Of Anthropogenic Load On Ecosystems Type Journal Article
  Year 2014 Publication Current Problems In Remote Sensing Of The Earth From Space Abbreviated Journal  
  Volume 11 Issue 1 Pages 237 - 244  
  Keywords Remote Sensing  
  Abstract Nighttime lights of the Earth’s surface are considered as integral and quantitative indicator of anthropogenic load on ecosystems in the framework of energetic approach for ecological safety level rating. Nighttime lights have high correlation with primary energy consumption at the regional level. Nighttime radiation recorded on satellite Suomi NPP (radiometer VIIRS) was recalculated to primary energy consumption. Photosynthetically active radiation absorbed by plants is determined from ecosystem primary production. EOS satellite system product MOD17 supplies global primary production information. Energetic approach is based on comparison of photosynthetically active radiation, absorbed by plants and anthropogenic energy load on ecosystems. Ecological safety level was calculated as the relation of photosynthetically active radiation to anthropogenic load on ecosystems. Ecological safety map for northwest part of European Russia was compiled with high spatial resolution on the basis of nighttime lights and ecosystem primary production satellite data. The highest level of ecological safety was defined for Karelia and Arkhangelsk region where anthropogenic load on ecosystems is relatively moderate and plants receive enough solar radiation to parry threats to ecosystem service. The very low ecological safety level was observed in St-Petersburg that is explained by high energy load and small area of urban agglomeration.

  Title Night Lights In Economics: Sources And Uses Type Journal Article
  Year 2020 Publication Journal of Economic Surveys Abbreviated Journal  
  Volume Issue Pages in press  
  Keywords Remote Sensing; Economics; Review  
  Abstract Night lights, as detected by satellites, are increasingly used by economists, typically as a proxy for economic activity. The growing popularity of these data reflects either the absence, or the presumed inaccuracy, of more conventional economic statistics, like national or regional GDP. Further growth in use of night lights is likely, as they have been included in the AidData geoquery tool for providing subnational data, and in geographic data that the Demographic and Health Survey links to anonymized survey enumeration areas. Yet, this ease of obtaining night lights data may lead to inappropriate use, if users fail to recognize that most of the satellites providing these data were not designed to assist economists, and have features that may threaten validity of analyses based on these data, especially for temporal comparisons, and for small and rural areas. In this paper, we review sources of satellite data on night lights, discuss issues with these data, and survey some of their uses in economics.

  Title Sustainable Potentials and Limitations of Using Media Façades in Egypt Type Journal Article
  Year Publication Ierek Press Abbreviated Journal  
  Volume Issue Pages 99 - 110  
  Keywords Lighting  
  Abstract Media Façade is expressed in many cities by providing new attractive city images. The term ‘Media Façade’ is a façade that is functionally and aesthetically specific and thus it represents the integration of architecture, technology. This integration is applied to represent new form of modern art and communication (Haeusler et al., 2012). Implementing new technology such as ” Media Façade ”following the purpose of fashion trend or adding new stylistic feature without being well studied will cause a massive impact on architecture.

This technology ” Media Façade ” started to be used in Egypt in various buildings with different functions. This paper will firstly illustrate what is Media Façade then state the social, cultural and environmental impacts of these techniques by analyzing local examples using SWOT analysis.

  Title Indicators of Electric Power Instability from Satellite Observed Nighttime Lights Type Journal Article
  Year 2020 Publication Remote Sensing Abbreviated Journal Remote Sensing  
  Volume 12 Issue 19 Pages 3194  
  Keywords Remote Sensing  
  Abstract Electric power services are fundamental to prosperity and economic development. Disruptions in the electricity power service can range from minutes to days. Such events are common in many developing economies, where the power generation and delivery infrastructure is often insufficient to meet demand and operational challenges. Yet, despite the large impacts, poor data availability has meant that relatively little is known about the spatial and temporal patterns of electric power reliability. Here, we explore the expressions of electric power instability recorded in temporal profiles of satellite observed surface lighting collected by the Visible Infrared Imaging Radiometer Suite (VIIRS) low light imaging day/night band (DNB). The nightly temporal profiles span from 2012 through to mid-2020 and contain more than 3000 observations, each from a total of 16 test sites from Africa, Asia, and North America. We present our findings in terms of various novel indicators. The preprocessing steps included radiometric adjustments designed to reduce variance due to the view angle and lunar illumination differences. The residual variance after the radiometric adjustments suggests the presence of a previously unidentified source of variability in the DNB observations of surface lighting. We believe that the short dwell time of the DNB pixel collections results in the vast under-sampling of the alternating current lighting flicker cycles. We tested 12 separate indices and looked for evidence of power instability. The key characteristic of lights in cities with developing electric power services is that they are quite dim, typically 5 to 10 times dimmer for the same population level as in Organization for Economic Co-operation and Development (OECD) countries. In fact, the radiances for developing cities are just slightly above the detection limit, in the range of 1 to 10 nanowatts. The clearest indicator for power loss is the percent outage. Indicators for supply adequacy include the radiance per person and the percent of population with detectable lights. The best indicator for load-shedding is annual cycling, which was found in more than half of the grid cells in two Northern India cities. Cities with frequent upward or downward radiance spikes can have anomalously high levels of variance, skew, and kurtosis. A final observation is that, barring war or catastrophic events, the year-on-year changes in lighting are quite small. Most cities are either largely stable over time, or are gradually increasing in indices such as the mean, variance, and lift, indicating a trajectory that proceeds across multiple years.
