This paper investigates two robust estimators of the scale parameter given data from a stationary, long range dependent Gaussian process. In particular the limiting distributions of the interquartile range and related τ-quantile range statistics are established. In contrast to single quantiles,...

One- and two-component bistable reaction-diffusion systems under external force are considered. The simplest case of a periodic forcing of cosine type is chosen. Exact analytical solutions for the traveling fronts are obtained for a piecewise linear approximation of the non-linear reaction term....

We reason in support of the universality of quantum spectral fluctuations in chaotic systems, starting from the pioneering work of Sieber and Richter who expressed the spectral form factor in terms of pairs of periodic orbits with self-crossings and avoided crossings. Dropping the restriction to...

Multinational companies that decide to relocate subsidiaries often appear socially irresponsible. Consumer boycotts are a common response to this type of action, especially in the subsidiary's homeland; however, the factors that motivate individual boycott decisions remain largely unexplored....

Mit dem Bilanzrechtsmodernisierungsgesetz wollte der Gesetzgeber unter anderem eine im Verhältnis zu den IFRS gleichwertige, d. h. ebenso entscheidungsnützliche, aber einfachere und kostengünstigere Alternative bieten. Um dieses Ziel zu erreichen, wurden verschiedene Wahlrechte gestrichen,...
