Usually, in monocentric city models, the spatial patterns of segregated ethnic groups are assumed to be ring-shaped, whereas in the 1930ies Hoyt showed that empirically wedge-shaped areas predominate. In contrast to Rose-Ackerman.s discussion of the in.uence within a ring-shaped pattern which...

In der aktuellen Politik ist seit Beginn der neuen Legislaturperiode Subventionsabbau Gegenstand der politischen Auseinandersetzung. Im Zusammenhang mit der so genannten Ökosteuer ist Ende der 1990er Jahre schon einmal eine ausgiebige Diskussion über die Bedeutung von Subventionen im...

The more important governmental cooperation and bureaucratic involvement become in ESDP, the more pressing becomes the issue of democratic control of executive cooperation. This article starts from the argument that parliamentary involvement in decision-making is of central importance for...

The distinction between negative and positive integration that has played a pivotal role in understanding the dynamics of the common market is also instrumental in explaining the dynamics of criminal law co-operation in the EU. Despite manifold differences between common market governance and...

The paper examines a key dimension of democratic control, namely parliamentary control of military missions and presents the findings of an in-depth case study on the EU’s maritime mission Atalanta that was launched to combat piracy off the coast of Somalia. The case study finds that none of...

Stochastic particle methods for the numerical treatment of the Boltzmann equation for dilute monatomic gases are considered. One particular stochastic model of particles with weights is introduced. Recent convergence results for this model are discussed. The introduction of certain degrees of...

In this paper, we review recent results concerning stochastic models for coagulation processes and their relationship to deterministic equations. Open problems related to the gelation effect are discussed. Finally, we present some new conjectures based on numerical experiments performed with...

The DSMC (direct simulation Monte Carlo) method for rarefied gas dynamics is studied. The behaviour of the underlying stochastic particle system is determined by three main components – the time step between subsequent collisions, the random mechanism for the choice of the collision partners,...

This paper examines whether decisions at the core of international security politics, namely decisions on the deployment of military forces, have undergone a process of politicization. It is guided by two interrelated questions, namely a) whether deployment decisions have been politically...

Usually in the monocentric city models, the spatial patterns of segregated ethnic groups are assumed to be ring-shaped, while early in the 1930ies, Homer Hoyt showed, that wedge-shaped areas predominate empirically. After Rose-Ackerman's discussion of the influence of aversion one group of...
