Risk group of persons with disabilities on the labour market in Prague from 2005 to 2015
Hošková, Laura ; Maule, Petr (advisor) ; Lukášová, Tereza (referee)
The theoretical part of the Bachelor Thesis comprehensively illustrates the status and representation of persons with disabilities (PWD) on the current labour market in the Czech Republic. In a general manner, the Thesis looks at the employment policy as well; especially its legislative basis in the legal framework of the Czech Republic and selected EU countries. Furthermore, the legal obligations of employers of PWD and the possibilities of fulfilling the mandatory share of PWD employment are stated. Findings of two qualitative employment studies are presented showing that PWD enter the labour market equipped with specialized competencies, which they are willing to complete by retraining programmes in case of need. The employers perceive the employment of PWD mainly as a financial profit, granted to them by the state; and the legislative conditions are a sufficient incentive for them. The questionnaire survey pointed out that the weakness in the employment of PWD is the lack of part-time jobs, which are highly demanded among them. Therefore the Thesis presents a solution, which could be the creation of shared work positions.

Use of Interest Rate Models for Interest Rate Risk Management in the Czech Financial Market Environment
Cíchová Králová, Dana ; Arlt, Josef (advisor) ; Cipra, Tomáš (referee) ; Witzany, Jiří (referee)
The main goal of this thesis is to suggest an appropriate approach to interest rate risk modeling in the Czech financial market environment in various situations. Three distinct periods are analyzed. These periods, which are the period before the global financial crisis, period during the financial crisis and in the aftermath of the global financial crisis and calming subsequent debt crisis in the eurozone, are characterized by different evaluation of liquidity and credit risk, different relationship between financial variables and market participants and different degree of market regulations. Within this goal, an application of the BGM model in the Czech financial market environment is crucial. Use of the BGM model for the purpose of predicting a dynamics of a yield curve is not very common. This is firstly due to the fact that primary use of this model is a valuation of interest rate derivatives while ensuring the absence of arbitrage and secondly its application is relatively difficult. Nevertheless, I apply the BGM model to obtain predictions of the probability distributions of interest rates in the Czech and eurozone market environment, because its complexity, direct modeling of a yield curve based on market rates and especially a possibility of parameter estimation based on current swaptions volatilities quotations may lead to a significant improvement of predictions. This improvement was also confirmed in this thesis. Use of swaptions volatilities market quotations is especially useful in the period of unprecedented mone- tary easing and increased number of central banks and other regulators interventions into financial markets that occur after the financial crisis, because it reflects current market expectations which also include future interventions. As a consequence of underdevelopment of the Czech financial market there are no market quotations of Czech koruna denominated swaptions volatilities. I suggest their approximations based on quotations of euro denominated swaptions volatilities and also using volatilities of koruna and euro forward rates. Use of this approach ensures that predictions of the Czech yield curve dynamics contain current market expectations. To my knowledge, any other author has not presented similar application of the BGM model in the Czech financial market environment. In this thesis I further predict a Czech and Euro area money market yield curve dynamics using the CIR and the GP models as representatives of various types of interest rates models to compare these predictions with BGM predictions. I suggest a comprehensive system of three criteria, based on comparison of predicti- ons with reality, to describe a predictive power of selected models and an appropria- teness of their use in the Czech market environment during different situations in the market. This analysis shows that predictions of the Czech money market yield curve dynamics based on the BGM model demonstrate high predictive power and the best 8 quality in comparison with other models. GP model also produces relatively good qua- lity predictions. Conversely, predictions based on the CIR model as a representative of short rate model family completely failed when describing reality. In a situation when the economy allows negative rates and there is simultaneously a significant likelihood of their implementation, I recommend to obtain predictions of Czech money market yield curve dynamics using GP model which allows existence of negative interest rates. This analysis also contains a statistical test for validating the predictive power of each model and information on other tests. Berkowitz test rejects a hypothesis of accurate predictions for each model. However, this fact is common in real data testing even when using relatively good model. This fact is especially caused by difficult fulfilment of test conditions in real world. To my knowledge, such an analysis of the predictive power of selected interest rate models moreover in the Czech financial market environment has not been published yet. The last goal of this thesis is to suggest an appropriate approach to obtaining pre- dictions of Czech government bonds risk premium dynamics. I define this risk premium as a difference between government bond yields and fixed rate of CZK IRS with the same length. I apply the GP model to describe the dynamics of this indicator of the Czech Republic credit risk. In order to obtain a time series of the risk premium which are necessary for estimation of GP model parameters I firstly estimate yield curves of Czech government bonds using Svensson model for each trading day since 2005. Resulting si- mulations of risk premium show that the GP model predicts the real development of risk premiums of all maturities relatively well. Hence, the proposed approach is suitable for modeling of Czech Republic credit risk based on the use of information extracted from financial markets. I have not registered proposed approach to risk premium modeling moreover in the Czech financial market environment in other publications.

Multicriteria games
Tichá, Michaela ; Dlouhý, Martin (advisor) ; Lachout, Petr (referee) ; Čičková, Zuzana (referee)
Theory of multicriteria games is a special field of game theory, when one or more players have at least two payoff functions and want to maximize simultaneously. The work introduces a number of new findings. It examined the concept of finding equilibria in pure strategies in noncooperative multicriteria game. It is possible to find all the equilibria in pure strategies by full search and solving two linear programs for each point. Furthermore, two linear programs are formulated for verifying that a selected point is the equilibrium of the game or not. In the noncooperative games is also introduced the concept that with knowledge of the equilibrium of bimatrix game determines preferences of the players. Although finding the equilibrium point of the bimatrix game is nonlinear problem, finding the preferences is linear problem. The latest findings in the noncooperative games is a generalization of the concept that solves multicriteria game by assigning weights to each criterion of each player. The work demonstrates that it may not be necessarily linear weights, but it can be more general function that describes the player's preference. The remaining part is devoted to knowledge in cooperative games. There is considered that the players know their preferences and are able to express them by weights. The game with known preferences is defined and solved with the use of bargaining theory. Then it is generalized to a case where players have more payoff functions, from which they can choose. Finally, the multicriteria case of voting game is defined. It is designed completely new concept, which selects the winning coalition in the voting game. This concept is then applied to the real situation after the elections to the Chamber of Deputies in 2013.

Phishing in the gaming industry
Nguyen Van, Thanh ; Luc, Ladislav (advisor) ; Veber, Jaromír (referee)
This bachelor thesis deals with a currently major issue of cyber security, which is phishing. The study is also specific in that it is focused on the gaming industry, which is subjected to a detailed analysis. The first goal of thesis is to acquaint the reader with problems of security risks of phishing in general and in game related fields. To achieve this goal, in the introduction of the theoretical part of the work, the general problem of phishing with a view on historical development and expansion is presented. Furthermore is described topic of gaming industry, its trends of videogames and security risks of online trading. The second goal is to give future and existing Steam users an overview of common phish-ing attacks and countermeasures. To achieve this goal, in the analytical part of the work, a specific gaming platform in online trading and distribution of game is selected, Steam from Valve. In the practical part of the work, eight selected phishing attacks are conducted to brief analysis and completed into a final evaluation and countermesures of all attacks.

The thesis deals with the financing of complete industrial plants exports with state support. The author is initially engaged in Export Strategy of the Czech Republic with an emphasis on companies founded by the state in order to support exports. Legislation in this field follows. The greatest emphasis is placed on methods of medium- and long-term export financing. One part of the thesis is a case study illustrating the possible practical way of financing export transactions.

The Conclusion of a Contract under the United Nations Convention on Contracts for the International Sale of Goods in Comparison with Czech National Legislation
Krčálová, Kristýna ; Boháček, Martin (advisor) ; Levý, Jan (referee)
This Master's thesis focuses on the United Nations Convention on Contracts for the International Sale of Goods (CISG), better known as the Vienna Convention. The main purpose of this thesis is to evaluate conditions for application of this international treaty and to assess the contracting process under the CISG including the similarities and differences with the Czech national legislation. Finally, it seeks an answer to the question, which of these rules (international or national) are more advantageous for a Czech contractual party with respect to concluding a contract. The thesis is divided into five parts. The first one represents an introduction to the CISG, its origin and the Czech Republic's attitude to it. The second part identifies the conditions for application of the CISG and therefore defines a subject and an object of an international contract of sale under the CISG. Both third and fourth parts gradually introduce two phases of the contracting process (offer and acceptance) including the relevant case-law. The last chapter strives to complete the contracting process with an analysis of the exact moment, when a contract is concluded, as well as with an analysis of a potential battle of the forms and its impact on a contract conclusion.

Interpretive principles in Verdi's operas
Beneš, Andrej ; HAJÓSSYOVÁ, Magdaléna (advisor) ; VOTAVOVÁ, Yvona (referee)
The master’s thesis deals with the theme creation of the opera production of Giuseppe Verdi with the focus on his opera Falstaff and deals with significant important interpretations of this opera. This dissertation is supposed to bring a complete picture of Verdi’s opera production pointing out some details which are not commonly known nor from the public nor in the professional music world. What appears in this work is Verdi’s correspondence (letters). I consider these letters an authentic source to understand Verdi’s creative and artistic intentions. Hereafter I portray an idea of how to perceive opera Falstaff not only from my point of view but I used the lead from the Italian reviews and musicology.

Subsidy Support of the Sustainable Waste Management
BEDNÁŘOVÁ, Renata
The subject of the dissertation is the issue of the waste management with special emphasis on the recycling of the construction and demolition waste. The recourse is an analysis of the key instruments regulating the activities and behaviour of market operators in this field toward fulfilling all-society priorities and principles of the sustainable development, where special accent is put on the area of subsidy policies and programmes. The aim of the dissertation is to analyse and evaluate the setting of the selected subsidy programme in terms of economic and ecological efficiency with the emphasis on the assessment of the impact on the recipient. The subject of the research will be a priority axis 4 "Improvement of Waste Management and Removal of Old Environmental Burdens" within the Operational Programme Environment 2007 - 2013. In the literature review basic concepts and important definitions are defined, followed by the comprehensive and complex searches of the problematics from different angles of view. First of all, the global aspect of environmental protection is discussed, broader historical, legal, economic and political contexts, that are essential fundament for understanding the current and future challenges both globally regionally, are summarized. Hereafter, a more detailed description of the situation of the European Union is followed, then the overview is completed by a detailed view at the state of the problematics in the Czech Republic. Subsequent chapters are devoted to a detailed analysis of the waste management sector, again in terms of global, European and national standpoint, in the end the view is focused on the key issue of the dissertation problematics of construction and demolition waste. In the application part the fulfilling of the stated objective of the dissertation through four defined hypothesis is solved. Hypotheses verify the efficiency and appropriateness of the setting of the system of subsidies in the frame of the monitored programme. The emphasis is imposed on the assessment of the impact of the allocated subsidies to the private entities on their economic and environmental efficiency.

Grammars with Restricted Derivation Trees
Koutný, Jiří ; Janoušek, Jan (referee) ; Vojnar, Tomáš (referee) ; Meduna, Alexandr (advisor)
V této disertační práci jsou studovány teoretické vlastnosti gramatik s omezenými derivačními stromy. Po uvedení současného stavu poznání v této oblasti je výzkum zaměřen na tři základní typy omezení derivačních stromů. Nejprve je představeno zcela nové téma, které je založeno na omezení řezů a je zkoumána vyjadřovací síla takto omezené gramatiky. Poté je zkoumáno několik nových vlastností omezení kladeného na cestu derivačních stromů. Zejména je studován vliv vymazávacích pravidel na vyjadřovací sílu gramatik s omezenou cestou a pro tyto gramatiky jsou zavedeny dvě normální formy. Následně je popsána nová souvislost mezi gramatikami s omezenou cestou a některými pseudouzly. Dále je prezentován protiargument k vyjadřovací síle tohoto modelu, která byla dosud považována za dobře známou vlastnost. Nakonec je zavedeno zobecnění modelu s omezenou cestou na ne jednu, ale několik cest. Tento model je následně studován zejména z hlediska vlastností vkládání, uzávěrových vlastností a vlastností syntaktické analýzy.
