  Title The Light at Night Mapping Project: LAN MAP 1, the Tucson Basin Type Journal Article
  Year 2012 Publication Society for Astronomical Sciences 2012 (proceedings) Abbreviated Journal  
  Volume 31 Issue Pages 139-145  
  Keywords Skyglow  
  Abstract (down) Tucson, Arizona, once billed as the Astronomical Capital of the World, has long been home to at least ten major astronomical institutions and facilities. The region also hosts numerous productive amateur observatories and professional-amateur astronomical collaborations. In spite of the implementation of progressive night time lighting codes, the continued growth of the region has arguably deprived Tucson of its title, and threatens the future of some if not all of these facilities. It has become apparent that there are several difficulties in regulating this lighting environment. It is not easy to model the actual effects of new or changed lighting fixtures, there are compelling economic conflicts that must be considered, and adherence to various guidelines is often ignored. Perhaps the most fundamental problem is that there have historically been no comprehensive measures of either light at night or sky brightness over the extended growth areas. What measurements do exist are inhomogeneous and poorly accessible spot measurements at some observatory sites. These have little to tell us about the actual light distributions in the overall region, and rarely are informative of the specific light sources that offend the observatory sites. Tucson remains, for the time, an important astronomical resource. Because of its astronomical and lighting code circumstances, it is an interesting and valuable laboratory for studying these issues. In this paper we introduce an innovative new 5-year project to comprehensively map both sky brightness and associated artificial lighting over extended areas of development in the vicinity of important astronomical institutions. We discuss the various vectors employed in data collection; we outline the protocols used for each methodology, give examples of the data collected, and discuss data analysis and conclusions. This program has been underway since January 2012, and has already produced results of interest to professional and amateur astronomers alike.

  Title Public street lights increase house infestation by the Chagas disease vector Triatoma dimidiata Type Journal Article
  Year 2012 Publication PloS one Abbreviated Journal PLoS One  
  Volume 7 Issue 4 Pages e36207  
  Keywords Animals; Human Health  
  Abstract (down) Triatoma dimidiata is one of the primary vectors of Chagas disease. We previously documented the spatio-temporal infestation of houses by this species in the Yucatan peninsula, Mexico, and found that non-domiciliated triatomines were specifically attracted to houses. However, the factors mediating this attraction remained unclear. Artificial light has been known for a long time to attract many insect species, and therefore may contribute to the spread of different vector-borne diseases. Also, based on the collection of different species of triatomines with light traps, several authors have suggested that light might attract triatomines to houses, but the role of artificial light in house infestation has never been clearly demonstrated and quantified. Here we performed a spatial analysis of house infestation pattern by T. dimidiata in relation to the distribution of artificial light sources in three different villages from the Yucatan peninsula, Mexico. In all three villages, infested houses were significantly closer to public street light sources than non-infested houses (18.0 +/- 0.6 vs 22.6 +/- 0.4 m), and street lights rather than domestic lights were associated with house infestation. Accordingly, houses closer to a public street lights were 1.64 times more likely to be infested than houses further away (OR, CI95% 1.23-2.18). Behavioral experiments using a dual-choice chamber further confirmed that adult male and females were attracted to white light during their nocturnal activity. Attraction was also dependent on light color and decreased with increasing wavelength. While public lighting is usually associated with increased development, these data clearly show that it also directly contributes to house infestation by non-domiciliated T. dimidiata.

  Title ESTIMATION OF TRANSPORT DEMAND USING SATELLITE IMAGE: CASE STUDY OF CHIANG MAI, THAILAND Type Journal Article
  Year 2020 Publication International Journal of GEOMATE Abbreviated Journal  
  Volume 18 Issue 69 Pages 111-117  
  Keywords Remote Sensing  
  Abstract (down) Transport demand is one of the essential datasets for urban / transport planning and policy development. However, the full size of travel demand survey requires large amount of cost, therefore the survey is merely conducted in developing countries. Their policy decision might be based on the old and limited datasets. In this study we propose a new approach to estimate transport demand using the night-time light satellite image based on the correlation of these two factors. Taking the case of Chiang Mai Metropolitan area, we found a soft relationship between the night-time light intensity and trip generation/trip attraction. Transport survey data is provided by Chiang Mai University for the year 2016. NOAA provides cloud free monthly composite of night-time light satellite image (VIIRS-DNB) by Suomi-NPP satellite of which resolution is 15 arc-second (about 500m by 500m at equator). It is spatially more precise than zones of travel demand survey and monthly frequency. Applying the relationship between transport demand and night-time light intensity, we propose a method to update the transport demand with higher spatial resolution.

  Title Transparency and the quality of local public service provision Type Journal Article
  Year 2019 Publication The Quality of Government Institute Abbreviated Journal QOG  
  Volume Issue 5 Pages 1-43  
  Keywords Economics; Remote Sensing; public service delivery; Vietnam; Asia  
  Abstract (down) Transparency has been widely promoted as a tool for improving public service

delivery; however, empirical evidence is inconclusive. We suggest that the effects of transparency on service provision are contingent on the nature of the service. Specifically, transparency is more likely to improve the quality of service provision when street-level discretion is high, since discretion increases information asymmetries, and, in the absence of transparency, allows officials to target public services in suboptimal ways. Using finely grained data from the Vietnam Provincial Governance and Public Administration Performance Index between 2011–2017, we show that communes that experience increases in transparency also experience improved quality of education and health (services characterized by greater discretion), while the quality of infrastructure

provision (characterized by less discretion) bears no relation to increased transparency. The findings help us understand when transparency can improve service provision, as well the effects of transparency reforms in non-democratic settings.

  Title Light pollution modeling and detection in a heterogeneous environment: toward a night time aerosol optical depth retrieval method. Type Journal Article
  Year 2005 Publication Proceedings of SPIE 2005 -- Volume 5890, San Diego, California, USA. Abbreviated Journal  
  Volume 5890 Issue Pages  
  Keywords Skyglow; aerosol optical depth;  remote sensing; light pollution; artificial skyglow  
  Abstract (down) Tracking the Aerosol Optical Depth (AOD) is of particular importance in monitoring aerosol contributions to global radiative forcing. Until now, the two standard techniques used for retrieving AOD were; (i) sun photometry, and (ii) satellite based approaches, such as based DDV (Dense Dark Vegetation) inversion algorithms. These methods are only available for use during daylight time since they are based on direct or indirect observation of sunlight. Few attempts have been made to measure AOD behaviour at night. One such method uses spectrally ­ calibrated stars as reference targets but the number of available stars is limited. This is especially true for urban sites where artificial lighting hides most  of these stars. In this research, we  attempt  to provide an alternate method, one  which exploits artificial sky glow or light pollution. This methodology links a 3D light pollution model with in situ light pollution measurements. The basic idea is to adjust an AOD value into the model in order to fit measured light pollution. This method requires an accurate model that includes spatial heterogeneity in lighting angular geometry, in lighting spectral dependence, in ground spectral reflectance and in topography. This model, named ILLUMINA, computes 1st and 2nd order molecular and aerosol scattering, as well as aerosol absorption. These model features represent major improvements to previous light pollution models. Therefore, new possibilities for light pollution studies will arise, many of which are of particular interest to the astronomical community. In this paper we will present a first sensitive study applied to the ILLUMINA model.
