[T]he income and happiness relationship is . . . curvilinear . . . with a decreasing marginal utility for higher levels of income . . . . (Diener, Sandvik, Seidlitz, and Diener, 1993, 204; cf. also Diener and Biswas-Diener, 2002, 119) [W]e not only see a clear positive relationship [between happiness and GNP per capita], but also a curvilinear pattern; which suggest that wealth is subject to a ...

The Van Leer approach for the approximation of nonlinear scalar conservation laws is studied in one space dimension. The problem can be reduced to a nonlinear interpolation and we propose a convexity property for the interpolated values. We prove that under general hypotheses the method of lines in well posed in l ∩ BV and we give precise sufficient conditions to establish that the total variat...

This paper examines the following theme. A~ume we are given a consequence relation lof the form A1,. . . , An tB and an algorithmic proof system Stfor deciding (either in a recursive of RE manner) whether for given A1,.. . ,An,B the relation A1,. . . ,A, JB holds. Is it possible to perturb S~ into a proof system LS~ which is still complete for t-, and such that each A~ is used in the proof at m...

It has been argued recently that the antipsychiatry movement has transmogrified into a patient-based consumer movement. Instead, the author suggests, various activities and ideas that legitimately could be described as antipsychiatry, or, at least, as highly critical of psychiatry, are burgeoning. These activities include the works of intellectual scholars, such as disgruntled psychiatrists, cr...

In this article, we address the problem of confusion and co-text-loss in chat communication, identify requirements for a solution, discuss related work and present a new approach for addressing co-text loss in text-based chats. We report about first experiences with our solution and give an outlook on future work directions. The core idea of our solution MuViChat (multiple-visualization chat) i...
