Abstract
Background/Purpose: Global changes in the information society are placing ever greater emphasis on professionals in all areas of human activity and in the area of ICT (Information and Communications Technology) especially. This article provides methodology how to measure knowledge level requirements on ICT specialists in business, ICT and non ICT skills in graduates of tertiary education level. It shows also an example of data collecting in academic sphere and among business unites. Practical experiences from the five years research are presented at the end of in this ontribution. These results are successfully applied for human resource management and innovation management in competences of ICT professionals in small and medium enterprises (SMEs) in the Czech Republic.

Abstract
Background/Purpose: The paper presents a mathematical model for the optimal security-technology investment evaluation and decision-making processes based on the quantitative analysis of security risks and digital asset assessments in an enterprise. The model makes use of the quantitative analysis of different security measures that counteract individual risks by identifying the information system processes in an enterprise and the potential threats. The model comprises the target security levels for all identified business processes and the probability of a security accident together with the possible loss the enterprise may suffer. The selection of security technology is based on the efficiency of selected security measures. Economic metrics are applied for the efficiency assessment and comparative analysis of different protection technologies. Unlike the existing models for evaluation of the security investment, the proposed model allows direct comparison and quantitative assessment of different security measures. The model allows deep analyses and computations providing quantitative assessments of different options for investments, which translate into recommendations facilitating the selection of the best solution and the decision-making thereof. The model was tested using empirical examples with data from real business environment.

Abstract
Background/Purpose: In this paper, based on the analysis of official FAOSTAT and EUROSTAT data on poultry meat for 38 European countries for years 2007 and 2009, two hypotheses were examined. Firstly, considering four clustering variables on poultry meat, i.e. production, export and import in kg/capita, as well as the producer price in US $/t, using descriptive exploratory and cluster analysis, the hypothesis that the clusters of countries may be recognized was confirmed. As a result six clusters of similar countries were distinguished. Secondly, based on multiple regression analysis, this paper proofs that there exists the statistically significant relationship of poultry meat production on export and import of that kind of meat, all measured in kg/capita. There is also a high correlation between production, as a dependent, and each of two independent variables.

Abstract
Background/Purpose:
This article addresses the problem of why subordinates trust their managers based on the responses from 108 subordinates of seven Slovenian managers and from 138 subordinates of eight Swedish managers. The subordinates of these managers responded to a 20-item instrument tested for reliability and validity. In both samples the managers enjoyed different degrees of trust. The level of trust vested in Slovenian managers was higher than in Swedish ones. The kinds of managers’ actions that enhanced trust were similar amongst Swedish and Slovenian subordinates. Different socio-cultural contexts may theoretically explain why some other kinds of actions had contrasting effects between the samples. On the whole, the actions of managers explain trust in both countries. Subordinates’ trust in managers declines with the increasing hierarchical distance in both national samples. Managers need to show in action that they trust their subordinates, promote their interests, demonstrate appreciation of their subordinates, and solve problems.
