This paper finds that political freedom has a significant and non-linear effect on domestic terrorism, but this effect is not significant in the case of transnational terrorism. Some of our other novel findings are that while geography and fractionalization may limit a county’s ability to curb terrorism, the presence of strong legal institutions deters it.

BACKGROUND As modern humans, we spend the majority of our time in indoor environments. Consequently, environmental exposure to microorganisms has important implications for human health, and a better understanding of the ecological drivers and processes that impact indoor microbial assemblages will be key for expanding our knowledge of the built environment. In the present investigation, we com...

The science of geography, also literally called in Arabic "faces and slices of earth", involves a kind of land survey which emerged into Islam. There were several factors contributing to geography such as command of Islam to learning, Quran geographical themes, pilgrimage routes and wide-range Muslim conquests. This article attempted to examine two major schools of geography in the Isl...

We tested the hypothesis that leaf modifying arthropod communities are correlated with cottonwood host plant genetic variation from local to regional scales. Although recent studies found that host plant genetic composition can structure local dependent herbivore communities, the abiotic environment is a stronger factor than the genetic effect at increasingly larger spatial scales. In contrast ...
