Many theories in political science predict the spatial clustering of similar behaviors among neighboring units of observation. This spatial autocorrelation poses implications for both inference and modeling that are distinct from the more familiar serial dependence in time series analysis. In this paper, I examine how political scientists can diagnose and model the spatial dependence that is pr...

This retrospective population-based study was conducted to analyze spatial patterns of tuberculosis (TB) incidence in Si Sa Ket province, Thailand. TB notification data from 2004 to 2008 collected from TB clinics throughout the province was used along with population data to reveal a descriptive epidemiology of TB incidences. Global clustering patterns of the occurrence were assessed by using g...

Global assessment of human-environment interactions is intrinsically hierarchical, requiring that we infer how local and regional processes will manifest themselves in regional and global conditions, respectively. But the ability to embed local intensive case studies of social and ecological processes within spatially extensive regional or global demographic and environmental data is hindered b...

 Recognition of spatial patterns of drought plays an important role in monitoring, predicting, confronting, reducing vulnerability, and increasing adaptation to the hazard. The aim of this study is to identify the spatial distribution and analyze the annual, seasonal, and monthly spatial patterns of drought intensities in Iran. For this purpose, drought intensities were extracted from the month...
