Theoretical concepts such as management, managers roles and functions, forms of communication and the use of communication in the managers work are explained by a study of academic literature in the first part of the dissertation. The practical part of the dissertation is based on qualitative research using a questionnaire aimed at managers in the chosen organization Service Centre for Road Transport.

The name of my dissertation is ``The efficiency of primary prevention of drug addictions from the view of drug addicts as well as the drug experts in the Region of South Bohemia.{\crqq} The dissertation aims to provide an insight into the issue of perceiving the efficiency of drug addictions{\crq} primary prevention by individual target groups of the research. A method of qualitative research was chosen to reach the objective. Two research questions were specified as follows: 1.How is the efficiency of drug addictions{\crq} primary prevention perceived by individual target groups? 2. Is the primary prevention of drug addictions applied systematically, timely and to a sufficient extent? To obtain the data, a non-standardised questionnaire with rather open questions was used. The research sample contained at the end 40 addicts, possibly abstaining and 31 experts working in the field of drug problems. Using graphic charts as well as commentary description, the findings part shows the elicited situation regarding the issue. Most of the experts consider primary prevention rather effective. If expressed in percentage, 30% efficiency of drug addictions{\crq} primary prevention was the most frequent choice of answers. On the other hand, the addicts evaluated the prevention as rather inefficient; however, in the percentage expression they shared the number with the experts - 30% efficiency was the most frequent choice. What the experts considered the weakest point of the current situation was the lack of funds into the primary prevention and a strong anti-drug lobby as well as the absence or inappropriate evaluation of the efficiency of primary prevention. The addicts saw the weakest points of the primary prevention in the lack of information on the consequences, as the information on effects prevailed over the after-effects. The dissertation confirmed some of the presumptive facts (insufficient/inappropriate evaluation of the efficiency of primary prevention) and indicated the propriety of similar research with a more extended view. Such research should be systematic and long-term with a broad platform of cooperating experts and media.

The thesis focuses on the equity portfolio management with quantitative methods. We present 3 types of optimization objectives: One tries to find minimum variance portfolios, tangency portfolios and portfolios with maximized expected returns in the German stock market. It is possible to compare those investment opportunities with a market-cap weighted benchmark and an equal weighted portfolio. Expected returns of stocks are estimated with fundamental factor models. Risks of portfolios are estimated with 5 types of covariance matrices: the matrix calculated with historical returns, estimations with the single index model, Fama-French three factors model, fundamental factor model and the shrinkage method. Our results are doubled because of the demonstration of the impact of turnover constraint on portfolio performance measures (transaction costs are included in our calculations). One can see that optimized portfolios had attractive risk-return measures in the period 2005 - 2015. Benchmark and equal weighted portfolios were dominated and we consider them to be inefficient investments in our test.

This work deals with tax wedges (effective tax rates) for businesses in the Czech Republic. The goal is to use a methodology for measuring the tax wedges for analysis of tax burden on particular business in period 2004 to 2008. Effective tax rate particular firm is compared with the effective tax rates of enterprises in the Czech Republic and the European Union. To achieve that goal literature review, analysis and comparison method are used. The results of the analysis showed that the particular firm had at the beginning of the period a very high tax burden compared to the statutory tax rate. During the period, however, the effective tax rate of the company significantly reduced and thereby was closer to statutory tax rate. The company had a lot of nondeductible expenses which most significantly contributed to the high tax burden. Tax on corporate income for companies is included in the costs, so the company should try to minimize this expense and thereby reduce the effective tax rate.

This thesis aims to compare the tax burden on companies in terms of corporate tax rate in Czech Republic and Slovakia. Comparison of taxation between those countries is not only important in international statistics, but also because of the high impact of the tax burden on corporate decision-making on the allocation of investment.

The data used to calculate this indicator of tax burden were obtained from the Amadeus database. Based on the results of the two comparisons, it will be evaluated, in which country is the corporate income tax more favourable for the taxpayers.
