Title: Mathematical analysis and computer simulations of deformation of nonlinear elastic bodies in the small strain range. Author: Vojtěch Kulvait Department: Mathematical Institute of Charles University Supervisor: prof. RNDr. Josef Málek, CSc., Dsc. Abstract: Implicit constitutive theory provides a suitable theoretical framework for elastic materials that exhibit a nonlinear relationship between strain and stress in the range of small strains. We study a class of power-law models, where the nonlinear dependence of strain on the deviatoric part of the stress tensor and its trace are mutually separated. We show that these power-law models are capable to describe the response of a wide variety of beta phase titanium alloys in the small strain range and that these models fit available experimental data exceedingly well. We also develop a mathematical theory regarding the well-posedness of boundary value problems for the considered class of power-law solids. In particular, we prove the existence of weak solutions for power law exponents in the range (1, ∞). Finally, we perform computer simulations for these problems in the anti-plane stress setting focusing on the V-notch type geometry. We study the dependence of solutions on the values of power law exponents and on the V-notch opening angle. We achieve...

Thesis deals with complex process of creation of new bankruptcy model for predicting business failure, while this process involves selection of quality sample, verification of classification accuracy of already existing bankruptcy models, profile analysis and finally the derivation of specific equation of bankruptcy model. The derivation is performed by using two selected statistical methods, discriminant analysis and logistic regression. Two bankruptcy models Bürger's index DA12 and Bürger's index LR12 were derived by using the mentioned statistical methods. The new models distinct advantage is, unlike already existing and renowned bankruptcy models, that they are focused on classification of micro and small enterprises in terms of Czech Republic, while classification accuracy one year before failure is by individual models 74.8 % and 81.87 %. Derived models have clear interpretation (no grey zone) and easy calculation, which brings a possibility for micro and small entrepreneurs to check their business partners in terms of failure prediction.

The aim of this thesis is to evaluate the system of municipality incomes in the Czech Republic with respect to specifics of small municipalities. In last few years these municipalities have become a frequently discussed topic because of their lower incomes. The legislation has been devoting to this problem since 2008 and the differences between large and small municipalities in the Czech Republic were removed. There is income analysis of all municipalities in the Czech Republic from 2000 up to 2012 in this thesis. The municipalities were divided into two groups. The first group contains small villages, defined as municipalities up to 499 inhabitants. In the second group there are other municipalities of the Czech Republic except small villages, statutory cities and the Capital City of Prague. The real data were recalculated per head for this analysis and minimum, maximum, median and arithmetic mean were found. Variability of incomes is evaluated from these results. Regression and correlation analysis is made in some groups of revenues because of finding dependence among variables. Disparity in incomes of small towns and other communities is assessed by comparing the arithmetic means and medians between groups of municipalities using a Two-Sample t-test and Mann-Whitney test. Revenue growth is evaluated determination of the trends of the time series using linear regression. Some specifics in financing small villages were found from these analyzes. There was also confirmation of the hypothesis that small municipalities have lower incomes per an inhabitant.

The goal of this thesis is to assess the link between labour productivity and firm competitiveness. An indispensable condition is to identify appropriate indicators measuring competitiveness. The link is examined in small and medium-sized companies active in manufacturing industry, specifically in section CZ-NACE 10. Manufacture of food products. First, an analysis of labour productivity and selected competitiveness indicators is made. Selected competitiveness indicators are Return on Assets (ROA), Return on Sales (ROS), Current Liquidity and index IN05. The relationship between labour productivity and competitiveness measured by selected indicators is examined by correlation and regression analysis. The significant positive link was found between labour productivity and competitiveness measured by ROA and ROS. Small and Medium-sized companies active in food industry can improve their ROA and ROS, and through this also competitiveness, by increasing their labour productivity. These indicators have also proved to be an appropriate tool for measuring the competitiveness of the company, especially in the food industry in the Czech Republic. The link between labour productivity and competitiveness measured by current liquidity and index IN05 was not explained in more detail.

Small and medium-sized enterprises perform important task in economy. To the category fall into enterprises to 250 employees. They supply social background and make for limitation of migration inhabitantes abroad or their inland. For development of small and medium-size enterprises in south Bohemia and Lower Bavaria serve programmes for their support. Entrepreneurs have possibility cooperation with organisations which offer facilities for sphere facilitation of bussines. Through these institutions happenes link-up including cooperation between Czech-German regions.

Thesis is focused on the development of the business plan of the company WOLF dětem, which sells children's and baby range. The work deals with the evaluation of the current situation of the company through analysis of internal and external conditions. On the basis of these analyses and the results of the questionnaire investigation, it was determined the proposal of amendments for the improvement of the business plan.

The thesis describes a biosocial model of status stratification in face to face groups. The model is based on the belief that human status behavior is evolutionary extension of animal status behavior (especially primates). Each person of a group is equipped with a signaling mechanism that signals the status of domination or submision (or the status he ought to have). Status communication is among humans very subtle and primarily occurs at a nonverbal level. Status stratification often takes place automatically without the knowledge of the subjects. The biosocial model criticizes classical authors of social stratification, who explain the mechanism primarily at the cognitive level. In the practical part, the thesis attempts to use new methodology to verify the main assumption of an implicit stratification mechanism that is able to function without the involvement of cognition. The research works with a group of people with 6 probands. To indicate status in a group, playing cards were used. In each group, individuals were artificially assigned positions by playing cards. Subsequently, it was recorded how these artificial positions were reflected in the real position of member of the group. In the second part, the influence of personality trait on the position was measured. The main assumption could...

In the context of human resource management can be argued that employee selection process is a major activity. This process is essentially based on competencies so job applicants including university graduates with an economic education, should have the desirable core and key competencies that result from job requirements. The aim of this doctoral dissertation is to build up a competency model of economically educated university graduates, according to the needs of employers from the South Bohemian Region's small and medium-sized enterprises and to identify the level of desirable key competencies of students of the Faculty of Economics, the University of South Bohemia in České Budějovice. Core and key competencies' preferences were collected through the questionnaire survey from the 189 human resource managers. The competency model creation was based on the statistical analysis of the identified results. Following the determined employers' preferences of the competencies, the skills of Faculty of Economics' students were also tested to find out their current level of key competencies.

Work to the theme "Analysis of insurance products for small and medium sized enterprises" tries to find the optimal variant of insurance of enterprise for the given company. These variants, also the given insurance companies, are compared by using of monocriteria and multicriteria evaluation of variants. It is possible to apprise basic concept in the first part, relating to insurance industry, insurance, enterprise, small and medium sized enterprises, mono and multicriteria evaluation of variants. There is a given company defined in the practical part, what are these variants evaluate for. There are also requests defined, that a company holder determines with a help of insurance broker, and then insurance offers are in this part defined. I used a method of monocriteria evaluation that supposes pessimistic approach for evaluation of variants. The aim of this evaluation was to determine which combination of insurances would be for the businessman and his company the optimal variant. Variants were evaluated with the help of multicriteria evaluation later, specifically Saaty´ method of weight determination and AHP method for order determination. Criteria, which were evaluated, are for example insurance premium over the discount that was offered through individual insurance companies, requirements for the security of buildings that provide insurance companies, etc. Four variants were evaluated. Today´s businessmen often solve problem, how they should protect themselves and their business against risks that can threaten. At this moment it is important to realize not only what type of risks threaten the business, but also the extent of its. When a businessman decides to one insurance option, it´s necessary to navigate himself through the offers of insurance companies and even get advice from an insurance broker. He can also for example decide based on personal experience with the insurance company. It´s definitely important to analyse the offers from different insurers.
