Spatial statistical methods including Cokriging interpolation, Morans I analysis, and geographically weighted regression (GWR) were used for studying the spatial characteristics of polycyclic aromatic hydrocarbon (PAH) accumulation in urban, suburban, and rural soils of Beijing. The concentrations of PAHs decreased spatially as the level of urbanization decreased. Generally, PAHs in soil showed...

New contours of global inequality present new challenges for global health, and require that we consider new kinds of health issues as global. I provide a number of illustrations, arguing the need for a political science of health that goes beyond conventional preoccupations with formal institutional and interstate interactions and takes into account how globalization has affected the health po...

My paper has two parts. First, I talk about the golden rule. After introducing the rule and its global importance, I explain why many scholars dismiss it as a vague proverb that leads to absurdities when we try to formulate it clearly. I defend the golden rule against such objections. Second, I talk about the golden rule in Persia and Islam; I consider Persian sources (Muslim and non-Muslim) an...

In his recent commentary, Gorik Ooms argues that “denying that researchers, like all humans, have personal opinions … drives researchers’ personal opinion underground, turning global health science into unconscious dogmatism or stealth advocacy, avoiding the crucial debate about the politics and underlying normative premises of global health.” These ‘unconscious’ dimensions of global health are...

This study developed a system of automatic classification of shoeprint images into groups belonging to the same sole pattern. When presented with an image of a new shoeprint the system displays a ranked sequence o f shoeprint images from the database. The shoeprint images are ranked from best match to worst match in terms of the pattern of the shoeprint. For this study a database o f 503 shoepr...
