Abstract Background Undernutrition is a major public health concern among under-five children in many developing countries. This work evaluated the overall prevalence of under-nutrition by using composite index anthropometric failure (CIAF), which helps detection with multiple failures. research also includes Spatio-temporal distribution childhood failures across time. Methods Secondary data wa...

This paper focuses on propagation of location errors in spatial data analysis. Specifically, it investigates how location errors impacts local spatial autocorrelation indices that often are used to identify spatial clusters. Results of a simulation experiment using heavy metal soil sample points in Syracuse, NY, are summarized. In the simulation experiment, artificial location errors were intro...

BACKGROUND Crimean Congo hemorrhagic fever (CCHF) is a tick-borne viral zoonotic disease that has been reported in almost all geographic regions in Pakistan. The aim of this study was to identify spatial clusters of human cases of CCHF reported in country. METHODS Kulldorff's spatial scan statisitc, Anselin's Local Moran's I and Getis Ord Gi* tests were applied on data (i.e. number of laborat...

The controversial Section 8 Housing Choice Voucher program is the largest federal low-income housing program. Using GIS-based spatial clustering analysis (Getis–Ord’s Gi statistic) and multiple linear regressions, in this paper, the authors examine the locational patterns of more than 13,600 Section 8 housing units in Jefferson County, Kentucky, and explore key social, economic, demographic, an...

To achieve sustainable urban development, it is essential to gain insight into the spatial and temporal differentiation characteristics driving mechanisms of thermal environment (UTE). As urbanization continues accelerate, human activity landscape configuration composition interact complicate UTE. However, differences in UTE-driven at different stages remain unclear. In this study, UTE Shenyang...

Given rapid global urban development, increases to impervious surfaces, population growth, building construction, and energy consumption result in the heat island (UHI) phenomenon. However, spatial extent of UHIs is not clearly mapped many UHI studies based on a remote sensing approach. Therefore, we developed method extract during period from 2000 2021 Nanjing, China, explored impact two- thre...

Assessments on the spatial pattern of ecological restoration potential provide insights into current status ecosystem health, facilitate identification hotspots degradation, and further serves as a link that bridges regional planning with specific efforts. The goal this study was to reconstruct pattern, through establishing an health assessment model encompassing four elements vigor, organizati...

This paper advances a growing body of mobile mapping work which captures building scale tornado damage in order to reveal vulnerabilities, or protections, within an otherwise apparently homogenous damage path. The hope is to find how micro geography, or built environment structure patterning might lead to policy advances with regards to rebuilding of critical infrastructure in tornado prone are...
