Statistical modeling of traffic crashes has been of interest to researchers for decades. Over the most recent decade many crash models have accounted for extra-variation in crash counts--variation over and above that accounted for by the Poisson density. The extra--variation--or dispersion--is theorized to capture unaccounted for variation in crashes across sites. The majority of studies have a...

The feed and feces of a continuously fed sheep were analyzed for carbon, hydrogen, and nitrogen, with oxygen as the remainder. The daily feed-feces weight difference was used as the reactant in an equation representing the rumen fermentation. The measured products were the daily production of volatile fatty acids (VFA), CH4, CO2, and ammonia. The carbon unaccounted for was assumed to be in the ...

We investigate a solution to the problem of multisensor perception and tracking by formulating it in the framework of Bayesian model selection. Humans robustly associate multi-sensory data as appropriate, but previous theoretical work has focused largely on purely integrative cases, leaving segregation unaccounted for and unexploited by machine perception systems. We illustrate a unifying, Baye...

Since van der Sandt and Geurts have put forward and extensively applied the notion of a fundamental identity of presupposition and anaphora, something like a universal consensus seems to have developed that this view is basically correct. Supposing that it is, and further supposing that it entails an empirical hypothesis, there are a number of facts that have so far remained unaccounted for. Th...

A recent observational study, which suggested that inhaled corticosteroids (ICS) with or without long-acting bronchodilators are effective at reducing all-cause mortality in chronic obstructive pulmonary disease (COPD) patients, may be subject to immortal time bias. This bias was assessed using a population-based cohort of 3,524 newly treated COPD patients from Saskatchewan, Canada, observed fr...

Development of the bioenergy sector is being actively pursued in many countries as a means to reduce climate change and fulfill international agreements such Paris Agreement. Although biomass for energy production (especially wood pellets) can replace carbon-intensive fossil fuels, its net greenhouse gas impact varies, pellets also lead intensification forest harvests reduction carbon stocks. A...

Among environmental economists instrument choice has tended to come down to the task of ’getting the prices right’. Command-and-control interventions were viewed with suspicion. Recently, behavioral economics has revealed undesired interactions between price regulation and intrinsic motivation. We contribute by experimentally testing direct and persistence effects of taxes and command-and-contr...

BACKGROUND Aneurysmal rupture accounts for the majority of nontraumatic subarachnoid hemorrhage (SAH). Increasingly recognized is the occurrence of nontraumatic convexity SAH unaccounted for by aneurysmal rupture. CASE REPORT These presentations require consideration of rare but clinically significant sources of SAH. We report a patient presenting with prolonged mild headaches and acute onset...
