Hofer-Zehnder capacity and length minimizing paths in the Hofer norm
We use the criteria of Lalonde and McDuff to determine a new class of examples of length minimizing paths in the group Ham(M). For a compact symplectic manifold M of dimension two or four, we show that a path inHam(M), generated by an autonomous Hamiltonian and starting at the identity, which induces no non-constant closed trajectories of points in M , is length minimizing among all homotopic p...

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...
