  Title Applying Artificial Intelligence On Satellite Imagery To Compile Granular Poverty Statistics Type Journal Article
  Year 2020 Publication ADB Economics Working Paper Series Abbreviated Journal  
  Volume Issue 629 Pages  
  Keywords Remote Sensing  
  Abstract The spatial granularity of poverty statistics can have a significant impact on the efficiency of targeting resources meant to improve the living conditions of the poor. However, achieving granularity typically requires increasing the sample sizes of surveys on household income and expenditure or living standards, an option that is not always practical for government agencies that conduct these surveys. Previous studies that examined the use of innovative (geospatial) data sources such as those from high- resolution satellite imagery suggest that such method may be an alternative approach of producing granular poverty maps. This study outlines a computational framework to enhance the spatial granularity of government-published poverty estimates using a deep layer computer vision technique applied on publicly available medium-resolution satellite imagery, household surveys, and census data from the Philippines and Thailand. By doing so, the study explores a potentially more cost-effective alternative method for poverty estimation method. The results suggest that even using publicly accessible satellite imagery, in which the resolutions are not as fine as those in commercially sourced images, predictions generally aligned with the distributional structure of government-published poverty estimates, after calibration. The study further contributes to the existing literature by examining robustness of the resulting estimates to user-specified algorithmic parameters and model specifications.

  Title Implementasi Sistem Pengolahan Data Sky Quality Meter Berbasis Visual Basic Untuk Analisis Perubahan Tingkat Kecerahan Langit Type Journal Article
  Year 2020 Publication Jurnal Kumparan Fisika Abbreviated Journal  
  Volume 3 Issue 4 Pages 239-246  
  Keywords Skyglow  
  Abstract Light pollution dramatically affects the brightness of the sky. Sky brightness level can be measured using Sky Quality Meter (SQM). SQM data results are huge data. It needs an application to facilitate data processing. Microsoft Excel Visual Basic features can assist the SQM data processing. The study used observational methods of sky brightness with SQM. Data analysis using the moving average method. Software development used the waterfall model with five stages of modeling, namely: analysis, design, implementation, testing, and maintenance. The waterfall development model was able to create an SQM data processing system. The data with various columns can be selected automatically and quickly. Hence, it is able to graph the level of sky brightness versus time.

  Title Moonstruck sleep: Synchronization of human sleep with the moon cycle under field conditions Type Journal Article
  Year 2021 Publication Science Advances Abbreviated Journal Sci. Adv.  
  Volume 7 Issue 5 Pages eabe0465  
  Keywords Human health; sleep; synchronization; Moonlight  
  Abstract Before the availability of artificial light, moonlight was the only source of light sufficient to stimulate nighttime activity; still, evidence for the modulation of sleep timing by lunar phases is controversial. Here, we use wrist actimetry to show a clear synchronization of nocturnal sleep timing with the lunar cycle in participants living in environments that range from a rural setting with and without access to electricity in indigenous Toba/Qom communities in Argentina to a highly urbanized postindustrial setting in the United States. Our results show that sleep starts later and is shorter on the nights before the full moon when moonlight is available during the hours following dusk. Our data suggest that moonlight likely stimulated nocturnal activity and inhibited sleep in preindustrial communities and that access to artificial light may emulate the ancestral effect of early-night moonlight.

  Title Quantifying and Evaluating the Cultivated Areas Suitable for Fallow in Chongqing of China Using Multisource Data Type Journal Article
  Year 2021 Publication Land Abbreviated Journal Land  
  Volume 10 Issue 1 Pages 74  
  Keywords Remote Sensing  
  Abstract The quantitative evaluation of the suitability of land fallow is of great significance to the effective implementation of fallow system in rural China. The purpose of this study is to systematically evaluate the cultivated areas suitable for fallow in Chongqing, China. The results show that: (1) a comprehensive index of cultivated land fallow (ILF) was developed by employing a series of multi—source data, and the ILF has been proven as an effective proxy to identify the cultivated areas suitable for fallow; (2) cultivated land with ILF values above the average value accounts for 34.38% (9902 km2) of the total cultivated land; (3) the ILF is negatively correlated with the population density, transportation proximity, and proportion of inclined area. This study argued that the ILF can reflect the cultivated areas suitable for fallow in Chongqing and can provide guidance for the spatial distribution of cultivated land fallow. The findings indicated that the differences in geographical elements between karst and non—karst areas must be further investigated, and the evaluation accuracy of the cultivated areas suitable for fallow must be improved.

  Title Artificial light at night (ALAN) affects the downstream movement behaviour of the critically endangered European eel, Anguilla anguilla Type Journal Article
  Year 2021 Publication Environmental Pollution Abbreviated Journal Environmental Pollution  
  Volume in press Issue Pages  
  Keywords Animals  
  Abstract Artificial light at night (ALAN) is considered one of the most pervasive forms of environmental pollution. It is an emerging threat to freshwater biodiversity and can influence ecologically important behaviours of fish. The European eel (Anguilla anguilla) is a critically endangered catadromous species that migrates downstream to the ocean to spawn in the Sargasso Sea. Given the pervasive nature of ALAN, many eel will navigate through artificially lit routes during their seaward migration, and although considered negatively phototactic, their response has yet to be quantified. We investigated the response of downstream moving European eel to simulated ALAN using a Light Emitting Diode unit in an experimental flume. We presented two routes of passage under: (1) a dark control (both channels unlit), (2) low ALAN (treatment channel lit to ca. 5 lx), or (3) high ALAN (treatment channel lit to ca. 20 lx). Eel were: (i) more likely to reject an illuminated route when exposed to high levels of ALAN; (ii) less likely to select the illuminated channel when given a choice; and (iii) passed downstream more rapidly when the illuminated route was selected. This study quantified the response of the critically endangered European eel to ALAN under an experimental setting, providing the foundations for future field based research to validate these findings, and offering insight on the ecological impacts of this major environmental pollutant and driver of global change.
