From Sparks to Prairie Fires: Spatial Mechanisms of Group Mobilization∗
Scholars have frequently mentioned the link between a group’s settlement pattern and its involvement in violent conflict. In this paper, I develop a computational model to examine this relationship in detail. I argue that the settlement pattern of a group has an impact on group mobilization, because it determines how quickly mobilization can spread from a few extremists to the entire group popu...
متن کاملSeasonal Fires, Bison Grazing, and the Tallgrass Prairie Forb Arnoglossum plantagineum Raf
Fire and grazing can interact to affect the structure and composition of vegetation communities in a manner that may differ from the effects of fire or grazing that occurs in isolation of the other. In order to better understand the effects of a fire-grazing interaction at the level of an individual plant species, we studied the response of a perennial tallgrass prairie forb, Arnoglossum planta...
متن کاملEffects of Summer Fires on Woody, Succulent, and Graminoid Vegetation in Southern Mixed-prairie Ecosystems: a Review
Interest in the use of summer fires to restore southern Great Plains prairie ecosystems infested with woody plants and cactus is increasing, but information regarding effects on target and nontarget plant species is needed before this practice can be recommended. We review effects of summer and winter fires on mortality and growth of honey mesquite (Prosopis glandulosa), prickly pear (Opuntia p...

It is argued that the WTC fires, while unprecedented in form, magnitude and extent, resembled ...
متن کاملDetermination of Survivable Fires
At NASA, there exists no standardized design or testing protocol for spacecraft fire suppression systems (either handheld or total flooding designs). An extinguisher’s efficacy in safely suppressing any reasonable or conceivable fire is the primary benchmark. That concept, however, leads to the question of what a reasonable or conceivable fire is. While there exists the temptation to ‘over-size...
