Unconvential monetary policy adopted by ECB and FED in 2008-2015
Pörner, Marek ; Šetková, Lenka (advisor) ; Ševčíková, Michaela (referee)
The main aim of this thesis is to analyse the accomplishment of the goals set, namely those of the selected unconventional monetary policies approved by the Federal Reserve System and the European Central Bank in response to the last financial crisis. With the FED the attention is focused on Quantitative Easing, whereas with the ECB it is focused on the programmes called Enhanced Credit Support, SMP, OMT and EAPP. Important parts of this thesis are also the explanation of the transmission mechanism of the unconventional monetary policy, the evaluation of macroeconomic impacts of these non-standard tools, the comparison of procedures of the two monitored central banks, but mainly the analysis of selected risks related to those tools. The principal method was an empirical analysis supported by economic studies dealing with the issues mentioned above. In the thesis it was discovered that the individual goals of the monitored programmes were achieved (with the exception of the SMP). With the programme EAPP no conlusion can be drawn because the programme has not been finished yet. Nevertheless, these non-standard tools bring certain risks such as a creation of a bubble in the markets of assets, a redistribution of wealth, a spillover effect, etc. For that reason it will be possible to evaluate the overall effect of the unconventional monetary policies only after a longer time period.

Systém odměňování v malém IT podniku
Novotný, Lukáš ; Dvořáková, Zuzana (advisor) ; Cetkovský, Pavel (referee)
The topic of this thesis is reward management and its application in a small-sized IT enterprise. Its goals are to properly document and describe current reward system in the company, evaluate the system and recommend improvements for the system. The first two goals are reached via thorough research of the company through semi-structured interviews, employee satisfaction survey, participant observation and document examination and the last one by applying principles from the current literature and education to the results of the two previous goals. The findings are that the reward system, despite growing organically instead of designed, is relatively effective in some areas, but needs improvement in other areas. The main improvement areas are motivation by contingent pay, communication management and performance management. Relatively well working rewards are especially non-financial reward connected to the work environment and work itself.

The theory of redistribution and its application
Mihalčinová, Hana ; Dlouhý, Martin (advisor) ; Valenčík, Radim (referee) ; Peško, Štefan (referee)
The theory of redistribution systems is a practical extension of a game theory, which deals with a redistribution within a social system of more than two players with di?erent performances and ability to create coalitions. This thesis is divided into three chapters. The ?rst chapter describes the known knowledge of a game theory. The second chapter deals with the theory of redistribution systems. Using an elementary redistribution system and its generalization group behaviour when dividing a payment, achieved by a collective performance, is described. This part introduces the extension of the redistribution system to a compound redistribution system with a fractal structure. Furthermore the theory of discriminatory equilibrium and the theory of commonly acceptable equilibrium are veri?ed using the elementary redistribution system and utility theory. The third chapter deals with an application to the allocation of funds among faculty departments. A game theory approach was used to reduce the game to a non-cooperative game of two players by using the forming of coalitions. Also the theory of redistribution systems was applied when a reduction was used to create a non-cooperative two-player game. This reduced non-cooperative game between two players was converted to a cooperative play of more than two players by changing the rules of the game and allowing a formation of coalitions. In the practical part both of these approaches are compared with real data and a current state.

Proposing the financial performance prediction index for decision support of the hospital management
Hajdíková, Taťána ; Černá, Anna (advisor) ; Lieskovská, Vanda (referee) ; Lazar, Jaromír (referee)
Dissertation thesis deals with the managerial needs in the area of financial health. Managers need a tool to reveal the impending financial failure or to assess the financial quality of the organization. They link their decisions to performance, ability to pay, employee productivity, financial resources and financial risk. In the theoretical part of the thesis it is necessary to explain the non-profit sector and its connection with the hospital environment. It is also necessary to introduce models used both in the Czech Republic and abroad, which share common elements. The basic aim of this thesis is to propose a financial performance prediction index for decision support of the hospital management, the owners of hospitals and insurance companies. To achieve the basic goal, three sub-goals must be accomplished. The first goal is to divide the hospitals into healthy and unhealthy by using the multi-criteria methods. The second goal is, based on an expert approach with the support of statistical methods, the selection of indicators appropriate for the hospital environment and the third goal is to find a suitable method for the determination of weighted representation of individual indicators in the proposed index and to assemble the final form of the new financial index for the hospital environment.

STRAIN ENGINEERING OF THE ELECTRONIC STRUCTURE OF 2D MATERIALS
del Corro, Elena ; Peňa-Alvarez, M. ; Morales-García, A. ; Bouša, Milan ; Řáhová, Jaroslava ; Kavan, Ladislav ; Kalbáč, Martin ; Frank, Otakar
The research on graphene has attracted much attention since its first successful preparation in 2004. It possesses many unique properties, such as an extreme stiffness and strength, high electron mobility, ballistic transport even at room temperature, superior thermal conductivity and many others. The affection for graphene was followed swiftly by a keen interest in other two dimensional materials like transition metal dichalcogenides. As has been predicted and in part proven experimentally, the electronic properties of these materials can be modified by various means. The most common ones include covalent or non-covalent chemistry, electrochemical, gate or atomic doping, or quantum confinement. None of these methods has proven universal enough in terms of the devices' characteristics or scalability. However, another approach is known mechanical strain/stress, but experiments in that direction are scarce, in spite of their high promises.\nThe primary challenge consists in the understanding of the mechanical properties of 2D materials and in the ability to quantify the lattice deformation. Several techniques can be then used to apply strain to the specimens and thus to induce changes in their electronic structure. We will review their basic concepts and some of the examples so far documented experimentally and/or theoretically.

Parallel single-cell analysis of active caspase-3/7 in apoptotic and non-apoptotic cells
Ledvina, Vojtěch ; Klepárník, Karel
Caspases are proteases that play key role in the process of apoptosis, the programmed\ncell death. Among them, caspase-3 and -7 are main executioner caspases that cleave\nmany vital proteins during apoptosis and after their widespread activation, the process\ncannot be reversed. To analyze caspase-3/7 activation within single cells, a miniaturized\ndevice for parallel analysis of eight samples was developed. The assay is based on the\nmodified luciferin-firefly luciferase bioluminescence (BL) system. Individual\nsuspended cells were collected and transferred into detection microvials using a\nmicromanipulator. The bioluminescence was detected using a photon counting head\nwith cooled photcathode. The LOD suitable for detection of active caspase-3/7 in both\napoptotic and non-apoptotic cells was reached.

Intuition in creative process of animation movie
Nováčková, Jana Kristýna ; DĚCKÁ, Eliška (advisor) ; ČIHAŘOVÁ, Libuše (referee)
This work deals with the relation of emotions to contemporary experimental animation. It engages in the emotional experience of a viewer to non-narrative film storytelling and its means of expression.
At the same time, it examines what the creative processes and attitudes of filmmakers towards emotions in experimental animation are. Analysis of the questionnaires also reveals whether the creator counts on the viewer's specific interpretation of the film.

Vegetation succession and soil development on heaps from brown coal mining
Veselý, Martin ; Chuman, Tomáš (advisor) ; Šefrna, Luděk (referee)
Plant diversity and selected soil parameters from 36 sites placed on brown coal mining spoil heaps were analyzed and compared. Spontaneously revegetated or technically reclaimed spoil heaps of different age were situated in brown coal mining district of eastern Most basin in north western part of the Czech republic. Samples were sorted in groups according to vegetation growth and type. Plant diversity increases during succession development and is higher on non-reclaimed sites than reclaimed sites, where diversity decreases with time. Soil bulk density decreases during succession on all sites. Soil pH is decreasing too and this process is faster on spontaneously revegetated sites. Old successional forest type sites have very acid soils probably due to properties of original mineral matrix. Thickness of organic horizon and A horizon is increasing during succession and they appear in mid-aged sites first. Content of soil organic carbon is increasing continuously. Non-reclaimed sites reach higher contents, mainly because of higher content of fossil organic matter in spoil mineral matrix. Keywords: vegetation succession, soil development, reclamation, brown coal mining heaps

Neural Networks Between Integer and Rational Weights
Šíma, Jiří
The analysis of the computational power of neural networks with the weight parameters between integer and rational numbers is refined. We study an intermediate model of binary-state neural networks with integer weights, corresponding to finite automata, which is extended with an extra analog unit with rational weights, as already two additional analog units allow for Turing universality. We characterize the languages that are accepted by this model in terms of so-called cut languages which are combined in a certain way by usual string operations. We employ this characterization for proving that the languages accepted by neural networks with an analog unit are context-sensitive and we present an explicit example of such non-context-free languages. In addition, we formulate a sufficient condition when these networks accept only regular languages in terms of quasi-periodicity of parameters derived from their weights.
