Title Modeling population density based on nighttime light images and land use data in China Type Journal Article
Year 2018 Publication Applied Geography Abbreviated Journal Applied Geography
Volume 90 Issue (up) Pages 239-247
Keywords Remote Sensing
Abstract Population change is a key variable that influences climate change, ecological construction, soil and water use, and economic growth. Census data are always point data, whereas planar data are often required in scientific research. By using nighttime light (NTL) images and land use data, combined with the fifth and sixth census data of China at the county level, we carried out spatial matching on the population of each county, respectively, and established population density diagrams of China for 2000 and 2010, which had a spatial resolution of 1 × 1 km. The method proposed in this paper is relatively simple and has a high simulation precision. The results showed that during the first ten years of the 21st century, there are some remarkable characteristics in Chinese population spatial pattern change: 1) the “disappearance” of intermediate-density regions; namely, areas with a population density between 500 and 1500 persons/km2 have decreased by 41% during the ten years; 2) continuous growth of high-density regions; namely, areas with a population density of more than 1500 persons/km2 have increased by 76%; 3) an expansion tendency of low-density regions similar to high-density regions.

Title Exploring spatiotemporal patterns of electric power consumption in countries along the Belt and Road Type Journal Article
Year 2018 Publication Energy Abbreviated Journal Energy
Volume 150 Issue (up) Pages 847-859
Keywords Remote Sensing
Abstract Fully understanding spatiotemporal patterns of electric power consumption (EPC) is one of the key questions related to sustainable socioeconomic and environmental development in countries along the Silk Road Economic Belt and the 21st-Century Maritime Silk Road (hereinafter referred to as the Belt and Road countries). However, studies about spatiotemporal patterns of EPC in the Belt and Road countries are still scarce due to the lack of reliable data. This study attempted to investigate spatiotemporal patterns of EPC in the Belt and Road countries from multiple perspectives. Firstly, the Defense Meteorological Satellite Program’s Operational Linescan System (DMSP-OLS) nighttime stable light data were used to estimate EPC from 1992 to 2013. Subsequently, the mathematical statistic method, standard deviational ellipse, rank size rule, and correlation analysis were employed to evaluate the EPC change in detail. The results reveal that the EPC growth mainly occurs in the developing countries, especially in China. The geographical distribution of EPC in the Belt and Road countries is oriented in the Northwest-Southeast direction between 1992 and 2013. Based on the rank size rule analysis, the slope values of q are −2.392 and −2.175 between 1992 and 2013, with an average R2 value of 0.664, indicating a clear clustering pattern of EPC. It is also proved that GDP is a more important impact factor to EPC than the population. Our findings can offer an effective way to understand spatiotemporal evolution characteristics of EPC in the Belt and Road countries, and provide references for regional socioeconomic development and cooperation.

Title LOCALIZED LIGHT SENSORY IN RELATION TO GRAZING ACTIVITY OF ECHINOMETRA MATHAEI Type Journal Article
Year 2018 Publication Abbreviated Journal
Volume Issue (up) Pages
Keywords Animals
Abstract This paper offers insight on the regulation of nocturnal behavior in burrowing sea urchin Echinometra mathaei of the Pacific. While it is known E. mathaei maintains nocturnal hours of activity (primarily grazing, burrowing, and locomotion), it is unknown whether this pattern follows a circadian rhythm or responds to local conditions of darkness. Varying light treatments were tested to determine potential manipulation of active behavior and explore potential for habitat destruction. Light manipulation was used to determine the role light sensory plays in the regulation of normal behavior. First utilizing gradual manipulation and later utilizing sudden manipulation to differentiate response to light stimuli. It was determined that while E. mathaei maintains nocturnal

activity via localized light sensory, manipulation of latent hours could not be significantly reproduced. It was found that while light manipulation can be responsible for simulating hours of activity, light manipulation cannot replicate latent hours. Upon exploration of predator response capability in E. mathaei following manipulation, it was found that individuals exposed to prolonged periods of artificial light had slower predation response times than individuals acclimated to a regular pattern of light exposure. These findings connect potential habitat degradation via grazing behaviors of E. mathaei to anthropogenic activity in Mo’orea, French Polynesia.

Title Night light intensity and women's body weight: Evidence from Nigeria Type Journal Article
Year 2018 Publication Economics and Human Biology Abbreviated Journal Econ Hum Biol
Volume 31 Issue (up) Pages 238-248
Keywords Remote Sensing; Human Health; Adolescent; Adult; Body Mass Index; *Body Weight; Cross-Sectional Studies; Female; Health Surveys; Humans; Lighting/*statistics & numerical data; Middle Aged; Nigeria/epidemiology; Obesity/epidemiology; Overweight/*epidemiology; Prevalence; *Urbanization; Young Adult; *Bmi; *Nigeria; *Night light; *Obesity; *Overweight; *Urbanization
Abstract The prevalence of overweight and obesity are increasing in many African countries and hence becoming regional public health challenges. We employ satellite-based night light intensity data as a proxy for urbanization to investigate the relationship between urbanization and women's body weight. We use two rounds of the Demographic and Health Survey data from Nigeria. We employ both nonparametric and parametric estimation approaches that exploit both the cross-sectional and longitudinal variations in night light intensities. Our empirical analysis reveals nonlinear relationships between night light intensity and women's body weight measures. Doubling the sample's average level of night light intensity is associated with up to a ten percentage point increase in the probability of overweight. However, despite the generally positive relationship between night light intensity and women's body weight, the strength of the relationship varies across the assorted stages of night light intensity. Early stages of night light intensity are not significantly associated with women's body weight, while higher stages of nightlight intensities are associated with higher rates of overweight and obesity. Given that night lights are strong predictors of urbanization and related economic activities, our results hint at nonlinear relationships between various stages of urbanization and women's body weight.

Title Licht über Wien VI Type Journal Article
Year 2018 Publication Abbreviated Journal
Volume Issue (up) Pages
Keywords Skyglow
Abstract Im Zentrum Wiens sättigt die Erhellung der Nacht, am Stadtrand sinken die jährlichen Zuwächse, wäh-rend im Abstand von 36 Kilometern (Großmugl) die Nächte um 10 % pro Jahr heller werden.Der Gesamtaufwand der Wiener Lichtglocke liegt 2018 bei 37 MW. Der Verlauf von 2011 bis 2018 zeigt ein deutliches Lichtmaximum um 2014 und 2015. Danach stellen wir einen allmählichen Rückgang fest.Der Verlauf der Lichtglocke und noch deutlicher jener der Einzelstationen zeigt signifikante Schwankun-gen von Jahr zu Jahr. Zur Aufklärung der Ursachen, die weder astronomisch noch meteorologisch sind, wur-den monatliche Analysen des Lichtmessnetzes mit Daten des Luftmessnetzes der Wiener MA 22 kombiniert. Die natürliche Variation über das Jahr wurde genutzt, um Zusammenhänge zwischen den Monatsmedianen von Luftfeuchtigkeit und Feinstaub mit jenen der Globalstrahlungsdaten zu suchen.Von 2016 bis 2018 korrelieren die Globalstrahlungswerte mit der relativen Luftfeuchtigkeit und den Feinstaubwerten (PM10 und PM2,5). Die engste Beziehung besteht auf der Kuffner-Sternwarte, wo eine Verdoppelung der Luftfeuchtigkeit statistisch von einer Verzehnfachung der Globalstrahlung begleitet wird. Die gefundenen Relationen sind über einen Faktor 100 in der Globalstrahlung äußerst robust und die Koeffizienten der Relationen sind an allen Stationen sehr homogen.Damit stehen gut bestimmte Zusammenhänge zwischen der Luftgüte und dem Zustand der klaren Atmo-sphäre zur Verfügung. Das wird es erlauben, Lichtmessnetze auf Standardatmosphären zu beziehen und damit eine wesentlich bessere Vergleichbarkeit der Daten zu unterschiedlichen Zeitpunkten herzustellen.- 130 Gigawattstunden Jahresaufwand für die Wiener Lichtglocke- 8 Jahre Vermessung der Lichtglocke zeigen Ansätze eines Rückgangs der Lichtflut- Mehr Feinstaub bewirkt überproportional mehr Lichtverschmutzung
