Culture and perception of leadership: Ideal leader in the country of origin and the country of residence - case of Germany. Study report (part two)

The present paper is a supplement to the earlier report (Witkowski, Grotthus, 2011) from the intercultural research concerned with an ideal leader prototype from an immigrant's perspective. In the present part, the authors focus consecutively on four groups of foreigners (Poland, Eastern Europe, Latin Europe, Latin America) working in Germany. Comparison of outstanding leader prototypes in the country of origin and Germany yielded significant differences in all groups.

Summary

In article we present selected issues of age management in organizations. They pointed to the lack of rationale for the discriminatory policies of some companies to employees aged 50+. Attention of managers was paid to the problem of age management in organizations, conditioned by an increase in the number of employees 50+. In Poland, currently there are employed approx. 31% of workers in this group (64 years old). While in EU countries the employment rate for workers aged fifty years and older more than 50%. The article discusses the specifics of the development processes and changes in the phase of middle and late adulthood, characterizing the population of employees and pointing to the “strengths” of the group. Age management in the context of both pathology and positive practices was presented. Referring to the data the benefits of age management were indicated.

Abstract

Professional burnout - a comparative analysis considering the key sectors in Poland The article presents the results of empirical research referring to the problem of burnout caused by professional burnout among staff of the most significant sectors in Poland. The authors presents the first part of the research project which also covered re-examination conducted after the interval of nine months. The research focused at the search for predictors of the phenomenon of burnout which - according to the latest concept of Maslach and Leiter - are as follows: emotional exhaustion, cynicism ad a reduced sense of personal achievements. With the application of neural networks, both the impact of organisational factors (organisational climate, experience of organisational stress) as well as personality-based factors onto the presence of professional burnout was verified. The main application conclusions resulted from the first stage of the research were presented at the end of the article.

Summary

Dynamics of professional burnout - a comparative analysis considering the key sectors in Poland, part II The article is a continuation of the study presented in the text entitled: „Professional burnout - a comparative analysis considering the selected sectors in Poland”. Management. University of Zielona Góra, Faculty of Economics and Management, Vol. 16, No.2., (p. 87 - 102). The authors present the results of the second part of the research on analysing the phenomenon of burnout among employees of the major sectors in Poland. The present material relates to the results of the re-test conducted after the nine-month interval. One again the cause-effect dependency models for the verified variables were presented for all the tested employed people and separately for each of the specified sectors. The most relevant applicable conclusions resulted from the implemented research projected were formulated.

Abstract

Honey is valued for its therapeutic qualities which are attributed among others to its antibacterial multifactorial properties. However, all the factors that influence these properties have not been identified. The present study is focused on the antibacterial action of fatty acids originating from royal jelly, the larval food of honeybees. Aliphatic C8-C12 acids characteristic of this bee product had previously been identified in more than fifty different samples of honey originating from seven countries and in eleven samples of Polish herbhoney. Experiments were performed to ascertain the influence of acidity on the antimicrobial activity of the acids. In acidic nutrient media all tested aliphatic hydroxyacids and unsaturated dicarboxylic acids demonstrated antibacterial action against different microbes with minimal inhibitory concentrations between 0.048 and 3.125 mM. Our results confirm that part of the antibacterial activity of honey contributes to these compounds of bee origin.

Abstract

This paper addresses the problem of road safety regarding barrier placement as relative to the curb. A short summary of existing regulations is presented. Numerical simulations using the explicit finite element system Ls-Dyna are shown. In the analysis, variable distance between the barrier and the curb is assumed. The obtained result reveals that the distance has little impact on the working width of the barrier.
