Title Effect of artificial night lighting on temporally partitioned spiny mice Type Journal Article
Year 2011 Publication Journal of Mammalogy Abbreviated Journal Journal of Mammalogy
Volume 92 Issue 1 Pages 159-168
Keywords mice; animals; mammals; Acomys cahirinus; Acomys russatus; activity patterns; light night niche; light pollution
Abstract (down) We studied the effect of ecological light pollution on a rocky desert community, focusing on 2 spiny mouse congeners, nocturnal Acomys cahirinus (common spiny mouse) and diurnal Acomys russatus (golden spiny mouse). We hypothesized that in response to artificial illumination A. cahirinus will decrease its activity and A. russatus will increase its activity, and thus temporal overlap and interspecific competition could increase. Our study took place in 4 field enclosures: the 1st and 3rd months were controls with natural light, and in the 2nd month artificial illumination, simulating low levels of light pollution, was set for the first 3 h of the night. We implanted temperature-sensitive radiotransmitters to monitor mouse activity, and individual identification tags with automonitored foraging patches were used to track foraging behavior. A. cahirinus decreased activity and foraging with artificial lighting, restricting movement particularly in less-sheltered microhabitats, probably because of increased predation risk. Because illumination restricted both activity time and space, intraspecific encounters of A. cahirinus over foraging patches increased during and following the illuminated hours. However, diurnal A. russatus did not expand its activity into the illuminated hours, possibly due to the presence of competing A. cahirinus, or to nonfavorable environmental conditions. Therefore, overt interspecific competition was not affected by experimental light pollution. Light pollution had a negative influence by reducing overall activity and producing a relatively underexploited temporal niche, which may promote invasion of alien species that are less light sensitive; and by increasing intraspecific overlap in foraging A. cahirinus.

Title The importance of intrinsically photosensitive retinal ganglion cells and implications for lighting design Type Journal Article
Year 2015 Publication Journal of Solid State Lighting Abbreviated Journal J Sol State Light
Volume 2 Issue 1 Pages 10
Keywords Human Health; lighting; Melanopsin; ipRGC; Photoreceptors; Circadian; Visual perception; Color Contrast; Sensitivity; LED; Lighting Design
Abstract (down) We reviewed the role of melanopsin-containing intrinsically photosensitive retinal ganglion cells (ipRGCs) in light-dependent functions, including circadian rhythm that is important for health and visual perception. We then discussed the implications for lighting design.

Title Limiting visual magnitude and night sky brightness Type Journal Article
Year 2000 Publication Memorie della Società Astronomia Italiana Abbreviated Journal
Volume 71 Issue Pages
Keywords Skyglow
Abstract (down) We review the theory of visual thresholds and applications to the limiting magnitude of a telescope and of the eyes, based on Schaefers's model with minor improvements. We apply out formulation to the Yerkes Observatory refractor and to naked eye observations at Mount Wilson Observatory. We reanalyze Bowen's telescopic observations at Mount Wilson by his approximate method and by our more elaborate theory. An extension of his method leads to a determination of the night sky brightness of the visual activity of the observer is assumed to be average. Our more elaborate method allows a determination of the sky brightness, the visual acuity of the observer, and the average seeing during the observations.

Title Impact of Cataract Surgery on Motor Vehicle Crash Involvement by Older Adults Type Journal Article
Year 2002 Publication Jama Abbreviated Journal Jama
Volume 288 Issue 7 Pages 841
Keywords cataracts
Abstract (down) We report the results of the Impact of Cataracts on Mobility (ICOM) project that was designed to address the question, for those older drivers who have cataract, what is the impact of cataract surgery on crash rate in the 4 years following surgery compared with those who have cataract who do not elect surgery? Strengths of this study design are the use of a comparison group of patients with cataract who do not undergo surgery followed prospectively over the same time period and the statistical adjustment for potential differences in the surgery and no surgery groups at baseline that could serve as confounders for the hypothesized effect. Using a randomized design would have been unethical since cataract surgery with intraocular lens implantation is an accepted and proven standard of care.

Title Detection of rural electrification in Africa using DMSP-OLS night lights imagery Type Journal Article
Year 2013 Publication International Journal of Remote Sensing Abbreviated Journal International Journal of Remote Sensing
Volume 34 Issue 22 Pages 8118-8141
Keywords Remote Sensing
Abstract (down) We report on the first systematic ground-based validation of the US Air Force Defense Meteorological Satellite Program’s Operational Linescan System (DMSP-OLS) night lights imagery to detect rural electrification in the developing world. Drawing upon a unique survey of villages in Senegal and Mali, this study compares night-time light output from the DMSP-OLS against ground-based survey data on electricity use in 232 electrified villages and additional administrative data on 899 unelectrified villages. The analysis reveals that electrified villages are consistently brighter than unelectrified villages across annual composites, monthly composites, and a time series of nightly imagery. Electrified villages appear brighter because of the presence of streetlights, and brighter villages tend to have more streetlights. By contrast, the correlation of light output with household electricity use and access is low. We further demonstrate that a detection algorithm using data on night-time light output and the geographic location of settlements can accurately classify electrified villages. This research highlights the potential to use night lights imagery for the planning and monitoring of ongoing efforts to connect the 1.4 billion people who lack electricity around the world.
