Despite widespread application of the impure public good model, surprisingly little attention has been given to the model's equilibrium properties. This paper presents a proof that clearly shows sufficient conditions for existence and uniqueness of a Nash equilibrium. © 2007 Elsevier B.V. All rights reserved.

This paper describes an improvement of the reusability model of the SISAL language. The study of the object oriented paradigm limits leads us to propose several extensions promoting a higher reusability scheme. The paper contains the description of the FOL language and of its translator to SISAL as well as insights in our future work on impure eeects.

the notion of absorbent ordered filters in implicative semigroupsis introduced, and its fuzzification is considered. relations among (fuzzy) orderedfilters, (fuzzy) absorbent ordered filters, and (fuzzy) positive implicativeordered filters are stated. the extensionproperty for (fuzzy) absorbent orderedfilters is established. conditions for (fuzzy) ordered filters to be (fuzzy)absorbent ordered ...

BACKGROUND Placebo interventions can have meaningful effects for patients. However, little is known about the circumstances of their use in clinical practice. We aimed to investigate to what extent and in which way Swiss primary care providers use placebo interventions. Furthermore we explored their ideas about the ethical and legal issues involved. METHODS 599 questionnaires were sent to gen...

Recent work has distinguished “harm” from “purity” violations, but how does an act get classified as belonging to a domain in the first place? We demonstrate the impact of not only the kind of action (e.g., harmful versus impure) but also its target (e.g., oneself versus another). Across two experiments, common signatures of harm and purity tracked with other-directed and self-directed actions,...
