Der Transitionsprozess vom Kindergarten in die Schule im Spannungsfeld von Innovation und Tradition

Medienimpulse, 2023
Ausgehend von den vier Dimensionen medienkompetenten Handelns (Baacke 1997) und der Forderung von Ehlers (2020), dass das Spannungsfeld von Innovation und Tradition im Kontext der Digitalisierung mehr erfordert als einer bloßen technischen Umsetzung ...

Green's function method for handling radiative effects on false vacuum decay

, 2015
We introduce a Green's function method for handling radiative effects on false vacuum decay. In addition to the usual thin-wall approximation, we achieve further simplification by treating the bubble wall in the planar limit.

One-loop corrections to the metastable vacuum decay

, 2003
We evaluate the one-loop prefactor in the false vacuum decay rate in a theory of a self interacting scalar field in 3+1 dimensions. We use a numerical method, established some time ago, which is based on a well-known theorem on functional determinants ...

Out-of-equilibrium evolution of scalar fields in FRW cosmology: renormalization and numerical simulations [PDF]

, 1999
We present a renormalized computational framework for the evolution of a self-interacting scalar field (inflaton) and its quantum fluctuations in an FRW background geometry.

The effects of overwithholding and retroactive savings options on retirement savings: An experimental analysis

Contemporary Accounting Research, Volume 42, Issue 3, Page 1899-1928, Fall 2025.
Abstract In three experiments, we examine how the widespread phenomenon of overwithholding affects retirement savings and how the additional option at tax time of saving retroactively for retirement affects total savings levels. Our results show that overwithholding significantly reduces retirement savings. We show that this outcome can be explained by

Nonequilibrium evolution of Phi**4 theory in 1+1 dimensions in the 2PPI formalism [PDF]

, 2002
We consider the out-of-equilibrium evolution of a classical condensate field and its quantum fluctuations for a Phi**4 model in 1+1 dimensions with a symmetric and a double well potential. We use the 2PPI formalism and go beyond the Hartree approximation

Gauge Fields Out-Of-Equilibrium: A Gauge Invariant Formulation and the Coulomb Gauge

, 2001
We study the abelian Higgs model out-of-equilibrium in two different approaches, a gauge invariant formulation, proposed by Boyanovsky et al. \cite{Boyanovsky:1996dc} and in the Coulomb gauge.

Effective action for bubble nucleation rates [PDF]

, 2001
We develop a method to calculate the prefactor in the expression for the bubble nucleation rate. A fermion with Yukawa coupling is considered where a step potential can be used as a good approximation in the thin wall limit.

Optimum maintenance units in multi‐indenture systems

Quality and Reliability Engineering International, Volume 40, Issue 5, Page 2792-2821, July 2024.
Abstract This paper deals with an optimization problem of determining the maintenance units and age‐based inspection schemes to minimize the expected maintenance cost rate and satisfy a target system availability for multi‐indenture systems that have a modular structure with redundant units.
