Title Artificial light and nocturnal activity in gammarids Type Journal Article
Year 2014 Publication PeerJ Abbreviated Journal PeerJ
Volume 2 Issue Pages e279
Keywords Acclimation; Gammarus; Invertebrate drift; Light pollution; Multispecies freshwater biomonitor
Abstract Artificial light is gaining attention as a potential stressor to aquatic ecosystems. Artificial lights located near streams increase light levels experienced by stream invertebrates and we hypothesized light would depress night drift rates. We also hypothesized that the effect of light on drift rates would decrease over time as the invertebrates acclimated to the new light level over the course of one month's exposure. These hypotheses were tested by placing Gammarus spp. in eight, 75 m x 1 m artificial flumes. One flume was exposed to strong (416 lx) artificial light at night. This strong light created a gradient between 4.19 and 0.04 lx over the neighboring six artificial flumes, while a control flume was completely covered with black plastic at night. Night-time light measurements taken in the Berlin area confirm that half the flumes were at light levels experienced by urban aquatic invertebrates. Surprisingly, no light treatment affected gammarid drift rates. In contrast, physical activity measurements of in situ individually caged G. roeseli showed they increased short-term activity levels in nights of complete darkness and decreased activity levels in brightly lit flumes. Both nocturnal and diurnal drift increased, and day drift rates were unexpectadly higher than nocturnal drift.

Title Social Impact of Connected Landmark Lighting: A Social Sensing Approach Type Journal Article
Year 2020 Publication IEEE Internet of Things Magazine Abbreviated Journal IEEE Internet Things M.
Volume 3 Issue 1 Pages 64-67
Keywords Lighting; Society
Abstract The benefits of using light emitting diode (LED) lighting for landmarks extend beyond energy savings to the use of illumination for creating visual identity, placemaking, and increasing tourism. While measuring energy consumption is possible with metering technologies, thereby quantifying savings in energy costs, quantification of the social impact of landmark lighting is not straightforward. Measuring and monitoring social impact metrics is key to stakeholders investing in new connected LED lighting systems or upgrades of conventional lighting in order to realize the benefits of lighting that are beyond energy sustainability. We consider social sensing as an approach to quantifying social impact of landmark lighting. Using lighting at the Empire State Building and Bay Bridge as case studies, social sensing querying and data analytics aspects are presented. A number of practical lessons and technical directions for the use of social sensing in connected landmark lighting are then laid out.

Title Streetlights in the city: understanding the distribution of Houston streetlights Type Journal Article
Year 2017 Publication Abbreviated Journal
Volume Issue Pages
Keywords Lighting; Society
Abstract There are at least 173,724 streetlights in the city of Houston, or about 15 streetlights per mile of roadway in the average Houston neighborhood. But there is wide variation in streetlight density across those neighborhoods. This report offers several important findings. First, black and Hispanic neighborhoods have higher concentrations of streetlights than white neighborhoods. Second, mixed-income neighborhoods tend to have higher concentrations of streetlights than the city’s wealthiest and poorest neighborhoods.

In the context of this discussion, we should consider the possibility that some areas of the city are overly lit in addition to being concerned about the places without enough lights. There may be a point at which having more lights actually becomes a negative. We need to get a better understanding of the lived consequences of the level of available lighting before making any further decisions regarding city streetlights.

Title A sharper image? Estimates of the precision of nighttime lights as a proxy for economic statistics Type Journal Article
Year 2014 Publication Journal of Economic Geography Abbreviated Journal J of Econ Geog
Volume 15 Issue 1 Pages 217-246
Keywords Nighttime lights; luminosity; output measurement; national accounts; proxy measures; social science; economics; remote sensing
Abstract Much aggregate social-science analysis relies upon the standard national income and product accounts as a source of economic data. These are recognized to be defective in many poor countries, and are missing at the regional level for large parts of the world. Using updated luminosity (or nighttime lights) data, the present study examines whether such data contain useful information for estimating national and regional incomes and output. The bootstrap method is used for estimating the statistical precision of the estimates of the contribution of the lights proxy. We conclude that there may be substantial cross-sectional information in lights data for countries with low-quality statistical systems. However, lights data provide very little additional information for countries with high-quality data wherever standard data are available. The largest statistical concerns arise from uncertainties about the precision of standard national accounts data.
