In this article we develop a simulation model to evaluate the economic efficiency of fuel treatments and apply it to two sagebrush ecosystems in the Great Basin of the western United States: the Wyoming Sagebrush Steppe and Mountain Big Sagebrush ecosystems. These ecosystems face the two most prominent concerns in sagebrush ecosystems relative to wildfire: annual grass invasion and native conif...

In this article we develop a simulation model for estimating the economic efficiency of fuel treatments and apply it to two sagebrush ecosystems in the Great Basin of the western United States: Wyoming Sagebrush Steppe and Mountain Big Sagebrush. These two ecosystems face the two most prominent resource management concerns in sagebrush ecosystems relative to wildfire: annual grass invasion and ...

In the Anthropocene, coupled human and natural systems dominate and only a few natural systems remain relatively unaffected by human influence. On the one hand, conservation criteria based on areas of minimal human impact are not relevant to much of the biosphere. On the other hand, conservation criteria based on economic factors are problematic with respect to their ability to arrive at operat...

Variable results of pain alleviation in response to acupuncture have been reported, complicating its interpretation. Sources of variability are probably multi-factorial, including the contribution of gender related effects. Gender related variation in perceived pain has been discussed frequently, but documented effects of acupuncture referring to gender are sparse. Furthermore, factors such as ...

This paper draws on four bodies of literature to consider the determinants of healthy eating for low-income Canadians: a) the social determinants of health; b) socio-economic gradients in diet; c) food security; and d) the sociology of food. Though there is a paucity of data for Canada, it is very likely that, as in other industrialized countries, there are socio-economic gradients in diet such...

Proving a conjecture of Talagrand, fractional version the ``expectation-threshold" Kalai and second author, we show that $p_c (\mathcal{F}) = O(q_f(\mathcal{F})\mathrm{log}\ \ell(\mathcal{F}))$ for any increasing family $\mathcal{F}$ on finite set $X$, where $p_c(\mathcal{F})$ $q_f(\mathcal{F})$ are threshold ``fractional expectation-threshold" $\mathcal{F}$, $\ell(\mathcal{F})$ is maximum size...
