We derive fast solvers for discrete elliptic variational inequalities of the second kind as resulting from the approximation by piecewise linear nite elements. Following the rst part of this paper, monotone multigrid methods are considered as extended underrelaxations. Again, the coarse grid corrections are localized by suitable constraints, which in this case are xed by ne grid smoothing. We c...

Gelman’s article is a thought-provoking mix of opinions and creative methodology. I agree with Gelman that the disjunction of models and exploratory data analysis (EDA) in mainstream statistics is unsound. The assumption that models belong exclusively to confirmatory data analysis (CDA) is easily shown to be wrong in practice. Many uses of models, in particular model selection, are exploratory,...

Assuming that there are correct basic norms, is there a way to explain their correctness? Paul does not think so, and he argues that a certain family of strategies for explaining the correctness of one particular class of basic epistemic norms does not work. The norms in question are those which concern the acceptance of ID-sentences, i.e. sentences which are, or seem to be, the implicit defini...

The purpose of this paper is to provide a heuristic that can help to decide whether qualitative or quantitative system dynamics modeling is useful in organizational modeling projects. The heuristic depends on the initial problem formulation, in form of a question to be answered. The argumentation is based on conceptual musings and on two short case studies to exemplify the usage of the heuristi...
متن کاملAndreas Vesalius' corpses.
Judging from his writings, Andreas Vesalius must have had dozens of bodies at his disposal, thirteen of which were definitely from before 1543. They came from cemeteries, places of execution or hospitals. Not only did his students help him obtain the bodies, but also public and judicial authorities. At first, he used the corpses for his own learning purposes, and later to teach his students and...
