Initial effects ofthe grounding ofthe tanker Braer

Objective-To determine if the oil spillage from the tanker Braer had any immediate health effects on the exposed resident population. Design-Cohort study with a comparison against controls, exposure status being assigned on the basis ofgeographical location. Setting-Rural Shetland. Subjects-All those resident on or after 5 January 1993 (day 0) within 4 5 km of the site of tanker's grounding. Co...

The Descriptive Complexity ofthe

We investigate the complexity of the xed-points of bounded formulas in the context of nite set theory; that is, in the context of arbitrary classes of nite structures that are equipped with a built-in BIT predicate, or equivalently, with a built-in membership relation between hereditarily nite sets (input relations are allowed). We show that the iteration of a positive bounded formula converges...

Approximations ofthe Limiting

A simple analysis ofthe

We examine a stylized version of EPA auctions when agents know the list of values of sellers and buyers. Sellers and buyers behave strategically. We show that there are two types of equilibria: inefficient equilibria where no goods are traded and efficient equilibria where alI exchange occurs at a uniform price. We also provide examples of the EPA auction game under incomplete information when ...

Interacting Particle Systems Approximations ofthe

In this paper we consider the continuous time ltering problem and we estimate the order of convergence of an interacting particle system scheme presented by the authors in previous works. We will discuss how the discrete time approximating model of the Kushner-Stratonovitch equation and the genetic type interacting particle system approximation combine. We present quenched error bounds as well ...
