Production activities exert a negative impact on the environment through emissions of pollutants. Environmental policies aim at the implementation of abatement technologies to reduce these emissions. Cost-effectiveness analysis is often applied as a tool to find abatement strategies that yield a certain emission reduction at minimum direct abatement cost to the producer concerned. The strength ...

Pharmacological therapy with endoscopic band ligation (EBL) fails in 10 to 20% of patients to control acute bleeding caused by rupture of esophageal varices [1]. Initial failure to control bleeding or early rebleeding has a significant impact on mortality. To reduce the incidence of treatment failure and death, more aggressive therapies may be used in patients with high risk of treatment failur...

Let k be the least cardinal such that the real Une can be covered by k many nowhere dense sets. We show that k can be characterized as the least cardinal such that "infinitely equal" reals fail to exist for families of cardinality k. Let Baire (k) stand for: "The real line is not the union of k many nowhere dense sets (a set is nowhere dense iff its closure has no interior)". The property was e...

An experiment is reported examining dual-process models of belief bias in syllogistic reasoning using a problem complexity manipulation and an inspection-time method to monitor processing latencies for premises and conclusions. Endorsement rates indicated increased belief-bias on complex problems, a finding that runs counter to the “belief-first” selective scrutiny model, but which is consisten...
