Leadership in Catholic Social Teaching

The material subject of Catholic social science is man and his actions taken in the fields of politics, the economy and society. According to its rules each person should be engaged in building the world through the realization of his or her vocation. One kind of vocation might be leading people by acting in accordance with the Gospel and teachings of the Church. The most important values for the leader in this case would be: respect for human dignity and human rights, freedom, justice, the subsidiarity principle and cooperation due to creating the common good. The listed rules are realized by servant leadership, the idea functioning in the field of management that derives its origins from Christ’s speech: whosoever will be chief among you, let him be your servant (Mt 20:27)

Massive Fermion Emission from Higher Dimensional Black Holes

We study the effect of extra dimensions on the process of massive Dirac fermion emission in the spacetime of (4+n)-dimensional black hole, by examining the Dirac operator in arbitrary spacetime dimension. We comment on both bulk and brane emission and find absorption cross section and luminosity of Hawking radiation in the low-energy approximation.Comment: 14 pages, 10 figures, RevTex, to be published in Phys.Rev.D1

Corporate social responsibility in FC Barcelona as Carroll’s CSR pyramid in practice

Corporate social responsibility (CSR) is a subject of great interest to both theoreticians and practitioners of management as well as to international organisations that promote this idea among existing enterprises. Despite many years of research on CSR, there is no single binding definition of this concept, therefore for the needs of this publication, the definition of Archie B. Carroll, and the resulting approach to CSR implementation in companies, has been adopted. The aim of the article is to analyse CSR activities undertaken by FC Barcelona in the framework of a system derived from Carroll’s CSR pyramid, therefore its activities have been divided into four groups corresponding to the dimension of financial, legal, ethical and philanthropic responsibilities. Due to the commercialisation of football, FC Barcelona is treated as a global enterprise, considering, however, the specificity of regulations governing the sports sector as well as goods and services offered by the club. The research has been based on an analysis of literature and available documents published by the club itself as well as by international organisations regulating football tournaments on national and international levels. The study has indicated that FC Barcelona is taking action in all the dimensions of social responsibility highlighted in Carroll’s pyramid and can be seen as a socially responsible organisation, at the same time meeting expectations of its stakeholders.Publication of English-language versions of the volumes of the "Annales.

Shaping pension reform in Poland : security through diversity

All over the world, pension systems have financing difficulties that need to be addressed. There are three ways of dealing with pension systems problems - finance it to a greater extent from general revenues, rationalize the system, or a full-fledged reform. After several years of political and professional discussions, Poland decided to follow the latter path and introduced a new defined contribution multipillar system, consisting of a public National Defined Contribution, pay-as-you-go first pillar, a funded private second pillar, and voluntary funded third pillar. The new framework covers only retirement savings, while other benefits still remain under the old defined-benefit pay-as-you-go regime. The reform was launched on January 1, 1999. This paper presents the current situation of the pension system, the struggle for pension reform in the 1990s, structure, the long-term outlook of the new pension system and the main aspects of the system design as well as first experiences from the implementation process. Long-term projection show that the new system allows for greater financial stability of the public pension scheme and increases the savings rate with a positive impact on economic growth.Pensions&Retirement Systems,Information Technology,Banks&Banking Reform,Gender and Law,Children and Youth

Central black holes in giant radio quasars

We analysed optical properties of giant radio quasars (with radio structures larger than 0.7 Mpc). To this day it is unclear why only a small fraction of radio sources attain such large sizes. There are a number of hypotheses attempting to explain this phenomenon, however the one treated in this paper has not yet been investigated in detail. This hypothesis assumes that the giant linear sizes of radio structures are due to internal properties of their central active galactic nuclei i.e. the specific properties of super-massive black holes and/or their accretion discs. We investigated whether a direct relation exists between the properties of the central "engine" and the origin of the Mpc scale radio structures. In our analysis, we did not find any relation between black hole mass and radio core power, however, we found a weak correlation between the accretion rate and radio core power. We also found a relation between a black hole's mass and linear size of the radio structure. The obtained results may suggest that giant radio quasars are similar to those of smaller size. There are also indications that giant radio quasars may be more evolved sources as compared with smaller radio quasars

Tax Wedge and Skills: Case of Poland in International Perspective

The project intended to explain the causes of high structural unemployment in Poland. It is generally believed that the high level of unemployment in Poland is determined to a decisive degree by factors such as a restrictive labor code, high degree of unionization and/or the unemployment benefits system. The research provides macroeconomic and microeconomic evidence that the employment consequences of a tax wedge can be more severe for the low-skilled. Consequently, it argues that a high tax wedge can be potentially more harmful in countries abundant in this kind of labour. These results should send a strong message to policymakers, especially those in Central and Eastern Europe. The project was financed by a research grant provided by the Ministry of Education and Science, Poland and conducted by a team of CASE researchers: Marek Gora (coordinator), Mateusz Walewski, Artur Radziwill and Agnieszka Sowa. It was completed in the first quarter of 2006.tax wedge, labour market, employment, skills, New Member States, Poland

Bound on the mass of Majorana neutrinos after SNO and KamLAND

Presently the best terrestrial limit on light neutrino masses (m<2.2 eV) are given by the tritium beta decay experiments. Not maximal mixing of solar neutrinos following from the SNO and KamLAND together with neutrinoless double beta decay (( )0 ) data open the chance for better determination of the lightest of Majorana neutrino mass. We combine all available fits for the solar neutrino parameters and collect all Nuclear Matrix Elements (NME) calculations for the 76Ge, nucleus for which presently the most stringent limit on the ( )0 decay half-life time exist. We have shown that for some NME smaller bound on (m )min can be found. Unfortunately one order of magnitude discrepancies in NME calculations do not allow to give the final answer
