The Impact

The Levy–Levy–Solomon (LLS) model [M. Levy, H. Levy and S. Solomon, Econ. Lett.45, 103 (1994)] is one of the most influential agent-based economic market models. In several publications this model has been discussed and analyzed. Especially Lux and Zschischang [E. Zschischang and T. Lux, Physica A: Stat. Mech. Appl.291, 563 (2001)] have shown that the model exhibits finite-size effects. In this study, we extend existing work in several directions. First, we show simulations which reveal finite-size effects of the model. Second, we shed light on the origin of these finite-size effects. Furthermore, we demonstrate the sensitivity of the LLS model with respect to random numbers. Especially, we can conclude that a low-quality pseudo-random number generator has a huge impact on the simulation results. Finally, we study the impact of the stopping criteria in the market clearance mechanism of the LLS model.

Religious Landscape

The most important conclusions of this summarizing chapter are the following: The religious landscape of Eastern Europe is more diverse than that of Western Europe. The cases of Poland and the GDR confirm the hypothesis that there is a link between the diffusion of functions and the growth in the importance of religion. The strong processes of biographical individualization that occurred in the post-communist states did not necessarily intensify individual religiosity. The economic market model cannot be confirmed for Eastern Europe. There is in Eastern and Central Europe a demonstrable link between economic prosperity and the loosening of religious and church ties. What can act as a bulwark against the eroding effects of modernization is church activity on the one hand, and the everyday proximity, visibility, and concreteness of religious practices and rituals, symbols, images, and objects on the other.

Electron Energy Loss

We develop a theoretical approach to investigate the impact that nonlocal and finite-size effects have on the dielectric response of plasmonic nanostructures. Through simulations, comprehensive comparisons of the electron energy loss spectroscopy (EELS) and the optical performance are discussed for a gold spherical dimer system in terms of different dielectric models. Our study offers a paradigm of high efficiency compatible dielectric theoretical framework for accounting the metallic nanoparticles behavior combining local, nonlocal and size-dependent effects in broader energy and size ranges. The results of accurate analysis and simulation for these effects unveil the weight and the evolution of both surface and bulk plasmons vibrational mechanisms, which are important for further understanding the electrodynamics properties of structures at the nanoscale. Particularly, our method can be extended to other plasmonic nanostructures where quantum-size or strongly interacting effects are likely to play an important role.
