  Title New nighttime roadway lighting documentation applied to public safety at night: A case study in San Antonio, Texas Type Journal Article
  Year 2019 Publication Sustainable Cities and Society Abbreviated Journal Sustainable Cities and Society  
  Volume 46 Issue Pages 101459  
  Keywords Lighting; Public Safety; Security; Planning  
  Abstract Built environment and public safety professionals view street lighting as an important factor in improving the well-being of the community at night. Extant research that has examined the relationship between street lighting and public safety has found inconclusive or mixed results and has called for more extensive lighting metrics. Using new lighting measurement technologies and geographic information science, this study builds on previous work to demonstrate new metrics to consider when evaluating public safety, specifically crime and traffic accidents. Downtown San Antonio, Texas is used as a case study to explore illuminance levels on roadways and the driver’s eye, and how these metrics can be used to understand the lighting characteristics of where crime and traffic accidents occur. The findings indicate that the central downtown district in San Antonio has higher illuminance levels than the existing roadway lighting guidelines while the residential downtown neighborhoods have insufficient light levels. Statistical analysis reveals that roadway illuminance levels are higher in areas where no crime occurred and driver’s eye illuminance levels are lower in areas with no traffic accidents. The findings prove the usefulness of new lighting documentation techniques and support the importance of considering illuminance metrics when assessing crime and traffic accidents at night.

  Title Study on the emergy-based thermodynamic geography of the Jing-Jin-Ji region: Combined multivariate statistical data with DMSP-OLS nighttime lights data Type Journal Article
  Year 2019 Publication Ecological Modelling Abbreviated Journal Ecological Modelling  
  Volume 397 Issue Pages 1-15  
  Keywords Remote Sensing  
  Abstract Emergy analysis is one of the ecological thermodynamics methods. With a specific set of indicators, it is proved to be highly informative for sustainability assessment of national/regional economies. However, a large amount of data needed for its calculation are from official statistical data by administrative divisions. The spatialization of emergy in early researches were limited to the administrative boundaries. The emergy inside an administrative boundary renders a single value, which hides plenty of information for more precise regional planning.

This study develops a new methodology for mapping the spatial distribution of emergy density of a region. The renewable resource distribution can be mapped based on latest geospatial datasets and GIS technology, instead of solely relying on statistics and yearbooks data. Besides, a new spatialization method of non-renewable emergy based on DMSP-OLS nighttime lights data is proposed. Combined with the radiation calibration data, the problem of light saturation of DMSP-OLS nighttime lights data was solved to improve the emergy spatial detail of city centers. With a case study of Jing-Jin-Ji region, results showed that this method could generate a high-resolution map of emergy use, and depict human disturbance to the environment in a more precise manner. This may provide supportive information for more precise land use planning, strategic layout and policy regulation, and is helpful for regional sustainable development.

  Title The lighting transition in rural Africa — From kerosene to battery-powered LED and the emerging disposal problem Type Journal Article
  Year 2017 Publication Energy for Sustainable Development Abbreviated Journal Energy for Sustainable Development  
  Volume 39 Issue Pages 13-20  
  Keywords Lighting; Energy  
  Abstract People without electricity access, numbering today more than 500 million in rural Africa alone, have been using dim and sooty kerosene lamps and candles for their lighting purposes for decades. In the present paper, current lighting usage patterns are systematically assessed using detailed new survey data from seven countries across Sub-Saharan Africa. The data makes evident that a transition has taken place in recent years, both unnoticed by and without external support from governmental or non-governmental organizations: the rural population without electricity in Africa has replaced kerosene lights and candles by simple, yet more efficient and cleaner LED lamps powered by non-rechargeable batteries. Nevertheless, we also show that the discharged batteries are generally disposed of inappropriately in latrines or the nature. The toxic content of many dry-cell batteries and their accumulation at local litter hotspots may have harmful repercussions on health and the environment. We conclude by suggesting that rapid action is needed to, first, install an effective monitoring system on batteries that enter the continent and, second, put in place an appropriate waste management system.

  Title High-accuracy determination of internal circadian time from a single blood sample Type Journal Article
  Year 2018 Publication The Journal of Clinical Investigation Abbreviated Journal J Clin Invest  
  Volume 128 Issue 9 Pages 3826-3839  
  Keywords Human Health  
  Abstract BACKGROUND: The circadian clock is a fundamental and pervasive biological program that coordinates 24-hour rhythms in physiology, metabolism, and behavior, and it is essential to health. Whereas therapy adapted to time of day is increasingly reported to be highly successful, it needs to be personalized, since internal circadian time is different for each individual. In addition, internal time is not a stable trait, but is influenced by many factors, including genetic predisposition, age, sex, environmental light levels, and season. An easy and convenient diagnostic tool is currently missing. METHODS: To establish a validated test, we followed a 3-stage biomarker development strategy: (a) using circadian transcriptomics of blood monocytes from 12 individuals in a constant routine protocol combined with machine learning approaches, we identified biomarkers for internal time; and these biomarkers (b) were migrated to a clinically relevant gene expression profiling platform (NanoString) and (c) were externally validated using an independent study with 28 early or late chronotypes. RESULTS: We developed a highly accurate and simple assay (BodyTime) to estimate the internal circadian time in humans from a single blood sample. Our assay needs only a small set of blood-based transcript biomarkers and is as accurate as the current gold standard method, dim-light melatonin onset, at smaller monetary, time, and sample-number cost. CONCLUSION: The BodyTime assay provides a new diagnostic tool for personalization of health care according to the patient's circadian clock. FUNDING: This study was supported by the Bundesministerium fur Bildung und Forschung, Germany (FKZ: 13N13160 and 13N13162) and Intellux GmbH, Germany.

  Title Mechanistic, ecological, and evolutionary consequences of artificial light at night for insects: review and prospective Type Journal Article
  Year 2019 Publication Entomologia Experimentalis et Applicata Abbreviated Journal Entomol Exp Appl  
  Volume 167 Issue 1 Pages 37-58  
  Keywords Animals  
  Abstract The alternation of light and dark periods on a daily or seasonal time scale is of utmost importance for the synchronization of physiological and behavioral processes in the environment. For the last 2 decades, artificial light at night (ALAN) has strongly increased worldwide, disrupting the photoperiod and its related physiological processes, and impacting the survival and reproduction of wild animals. ALAN is now considered as a major concern for biodiversity and human health. Here, we present why insects are relevant biological models to investigate the impact of ALAN. First the phenotypic responses to ALAN and their underpinning mechanisms are reviewed. The consequences for population dynamics, and the community composition and functioning are described in the second part. Because ALAN provides new and widespread selective pressure, we inventory evolutionary changes in response to this anthropogenic change. Finally, we identify promising future avenues, focusing on the necessity of understanding evolutionary processes that could help stakeholders consider darkness as a resource to preserve biodiversity as well as numerous ecosystem services in which insects are involved.
