Abstract

We calculate the dynamics of tax evasion within a multi-agent econophysics model which is adopted from the theory of magnetism and previously has been shown to capture the main characteristics from agent-based based models which build on the standard Allingham and Sandmo approach. In particular, we implement a feedback of public goods provision on the decision-making of selfish agents which aim to pursue their self interest. Our results imply that such a feedback enhances the moral attitude of selfish agents thus reducing the percentage of tax evasion. Two parameters govern the behavior of selfish agents, (i) the rate of adaption to changes in public goods provision and (ii) the threshold of perception of public goods provision. Furtheron we analyze the tax evasion dynamics for different agent compositions and under the feedback of public goods provision. We conclude that policymakers may enhance tax compliance behavior via the threshold of perception by means of targeted public relations.

Abstract

This article examines the anthropological cognitive aspects of the contemporary theological thought of Hans Urs von Balthasar, with particular emphasis on the analysis of the relationship between agathology and theodrama. Starting from the Swiss theologian’s theatrical and literary inspirations, the key link between agathology and agogics is established which, in turn, explains why the Basel theologian chose the good as the starting point for his theodramatic reflections. Conversely, it is shown that theodrama cannot be exhausted in theoagatology. In order to understand the depth of theodrama, an extended analysis of the dialogical aspect and the issue of the drama of choice is necessary. However, the essence of theodrama is discovered only when the central role of the paradox related to the problem of mysterium iniquitatis is considered. The theodramatic approach to this mystery and the proposal of the Swiss theologian regarding the positive view of this problem in the light of the indefinite finality paradox immersed in the mystery of the cross are subjected to thorough analysis here.

Abstract

Nominal strength reduction in cross ply laminates of [0/90]2s is observed in tensile tests of glass fiber composite laminates having central open hole of diameters varying from 2 to 10 mm. This is well known as the size effect. The extended finite element method (XFEM) is implemented to simulate the fracture process and size effect (scale effect) in the glass fiber reinforced polymer laminates weakened by holes or notches. The analysis shows that XFEM results are in good agreement with the experimental results specifying nominal strength and in good agreement with the analytical results based on the cohesive zone model specifying crack opening displacement and the fracture process zone length.
