De Haan and Pereira [1] provided models for spatial extremes in the case of stationarity, which depend on just one parameter β > 0 measuring tail dependence, and they proposed different estimators for this parameter. This framework was supplemented in [2] by establishing local asymptotic normality (LAN) of a corresponding point process of exceedances above a high multivariate threshold, yieldin...

The range of a payoff function in an n-player finite strategic game is investigated using a novel approach, the notion of extreme points of a nonconvex set. A basic structural characteristic of a noncooperative payoff region is that any subregion must be non-strictly convex if it contains a relative neighborhood of a boundary point of the noncooperative payoff region. This can be proved efficie...

Agile software development, despite its novelty, is an important domain of research within software engineering discipline. Agile proponents have put forward a great deal of anecdotal evidence to support the application of agile methods in various application domains and industry sectors. Scientifically grounded empirical evidence is, however, still very limited. Most scientific research to dat...
