1 Abstract Representation This thesis concerns the institute of the representation in effective legislation of civil law particularly in the Act no. 89/2012 Coll., Civil Code. This institute is very important for each person, no matter it's age or profession, because everybody in his live needs to use the representation. Not only have I focused in my thesis on the part of the Civil Code which is called representation, but also on the other parts that contain representation as well. My thesis is divided into nine chapters, in which I am dealing with representation based on the decision of the court as well as the contract or the law. At the beginning my thesis describes historical basis of representation and also short glimpse to the previous legislation. The next chapter deals with chosen types of the representation that are not regulated in the chapter III of the Civil Code, but I also consider them as really important and very useful in practice. The most of the thesis is focused on the part of the Civil Code that is named the representation. Firstly general provisions are described where I specially focus on the power of attorney, its form and necessary provisions. In the representation based on contract belongs also procuration, where I included its origin, its extent, form and termination. The thesis...

The medial olivocochlear reflex (MOCR) is a brainstem-mediated reflex that reduces cochlear amplifier gain when elicited by sound. The MOCR may provide benefits such as protection from acoustic trauma and improved hearing in background noise. Measurement of MOCR effects may also have clinical applications. MOCR effects can be measured using transient-evoked otoacoustic emissions (TEOAEs), as amplitudes of TEOAEs are typically reduced during MOCR activation. The primary purpose of the current study was to quantify the repeatability of MOCR effects on TEOAEs because high repeatability in a healthy population is a necessary (but not sufficient) component of a clinically-useful test. A secondary purpose was to assess the relationship between MOCR strength and speech perception in noise. Twenty-one normal hearing subjects ages 18-30 participated. TEOAEs were elicited using 35 dB sensation level (SL) clicks. The MOCR was elicited using contralateral acoustic stimulation (CAS) consisting of 35 dB SL broadband noise. Sixteen measurements were made across a 5-week period (4 visits × 4 measurements per visit). TEOAEs were bandpass filtered in 1/6-octaves from 1-2 kHz. An individualized time-frequency analysis was used to select the largest TEOAE envelope peak within a restricted time analysis window. Responses were characterized as the complex ratio of TEOAEs obtained with versus without CAS. The statistical significance of effects was assessed. Results revealed generally high levels of stability across time, as assessed by the interquartile ranges of all results and as assessed by Cronbach's alpha. Four MOCR measurements appeared to be adequate to obtain a reliable baseline measurement. Individualized time-frequency analyses were also important for obtaining reliable measurements. However, several subjects showed stable baseline measurements but unusual patterns of variability at subsequent sessions. These changes did not appear to be the result of changes in auditory status, methodological issues, or equipment issues. No significant relationship was found between MOCR strength and speech perception in noise. Results suggest that MOCR measurements are stable in most subjects when using careful measurement and analysis methods, but that further work is needed to better characterize changes in MOCR and to validate the current methodology in a larger number of subjects.

(Contemporary Critique of Juristocracy) This theses deals with a comparative research of judiciaries of the United States, Israel and the Czech Republic. Consequently, it reaches a conclusion that all of these countries are undergoing a substantive political crisis, which leads to unhealthy empowerment of a judiciary system. The judiciary in abovementioned countries is moreover incapable of meeting challenges connected to the legislative deferrals, since the courts are unable to disconnects themselves from a social reality. The countries selected for the study was chosen in order to achieve as diverse sample as possible. That should lead to universally applicable outcome. Besides this empirical line of research, there is a deeper normative line attached. I believe it is vital to foresee a future political arrangement in a positive manner, even though there is a substantial risk of authoritarian regime's emergence during this transition. Still, the worst thing we can do is to kick a can of contemporary political imagination down the road forever. That prevents progress, but it also highlights another threat of authoritarian regime in name of protecting "freedom" against democracy or "democracy" against freedom. Regarding the content of the thesis, I pursue an abovementioned idea about highly...

The topic ``Elitism in nursing{\crqq} was chosen based on the author´s interest in this issue, which is considered very attractive, and tributary to the present time, when nursing in our country is undergoing a revolutionary change. Nurses gain new competences and become partners of physicians, new legislature related to the profession comes into effect continuously, there is an effort to enhance the prestige of nurses and thereby to increase their status in the eyes of both the medical and general public. As mentioned above, the entire field of nursing, the nursing education system and the nursing profession in our country has been undergoing a fundamental transformation for some time, which places high demands on information, lifelong learning, free access to the latest information on the course of events not only in our country but especially on the international professional scene. Nursing is a field that has multiple layers - from basic nursing care, which is within the competence of nurses, to a specialized nursing and superspecialized care, which requires thanks to advances in nursing science the highest possible level of education. To define the elite of the nursing profession, it is necessary to specify the elite as an exclusive social group. Through this study the author tried to describe the issue of elitism in nursing in a comprehensive form. The objective was to briefly characterize the current situation in terms of the relationship between different groups of nurses and also debate over the question: "What does it take to be a nurse?" Is it the knowledge of an intricate technique or empathic wiping sweat from a patient´s forehead? The new century makes the nurse think about the concept of extended roles in nursing, which should help elevate social status of the profession. A negative feature is that a nurse has been detracted from the kind of work for which she had become a nurse - the nursing care of a patient and the care of basic biological needs of a patient. Due to this aspect, a lot of nurses believe that enhancing the prestige of the nursing profession is not compatible with the term ``menial{\crqq} job relating to nursing. The research outcomes showed that in Czech nursing, there is a status called elitism, and that there are disciplines perceived as exclusive, the relationship between professionalization and elitism was also proved. The research survey noted a big shift in improving communication between nurses and patients compared to the past years, and the author hopes that also a better communication between nurses will contribute to the improvement of relations on both sides, both the exclusive and the so-called common, because a truly elite - exceptional nurse is the one who combines education with a good character.

This diploma thesis works with the hypothesis that the existence of oil, which is a non-renewable resource of energy with limited availability (geographically as well as in terms of the available amount)influenced internal formation and international relations of the Middle Eastern states, which are the primary world oil exporters. The main goal of this thesis is to analyse this assumption based on the history of oil industry and determine to what extent has the oil contributed to the current position of the Middle East in the international relations.

The main aim of diploma thesis "China - real threat for American hegemony?" is to answer the question whether China is trying to threaten American position of world hegemon. After the dissolution of USSR and the fall of Iron Curtain USA became the only world superpower. Balance of power theory assumes that the occurrence of leading actor in the system will invoke attempts of others to balance the power of the leader, or to weaken him. In current world political system there are powers whose power potential is growing. One of them is China, mainly because its fast growing and prospering economy. Author of the thesis works with the concept of hegemony based on hard and soft power and three types of exercising of power - three faces of power - as means of achieving its goals. Author analyses Chinese use of hard and soft power resources, that can be classified under three types of use of power. All policies are then examined from "balance of power" theory view. Author tries to find out which one of behavior "balancing" attempts to balance, weaken USA or "bandwagoning" - support of USA is prevailing in Chinese policies. According to the prevailing tendency of Chinese behavior towards USA the author is capable to state whether China can be considered as a threat for US hegemony.

Face aux questions émergentes relatives aux ethnies minoritaires dans les régions montagneuses du nord-ouest du Vietnam, la tendance actuelle est d'implanter le tourisme dans la communauté en le considérant comme un outil de développement local. Au-delà des approches théoriques, l'analyse des multiples projets mis en œuvre dans le cadre du tourisme "communautaire" montre que les effets négatifs sont nombreux, nuisibles souvent à la culture, à l'environnement, à la société. Dans un contexte de fort développement du tourisme communautaire au Vietnam, la thèse s'efforce d'ouvrir quelques propositions adaptées aux ethnies minoritaires en montagne du Vietnam, autour du concept d'écotourisme attaché à la communauté (l'EAC). En déterminant certaines causes de dysfonctionnement, préjudiciables à une mise en tourisme durable, la thèse propose un modèle de gestion de l'EAC adapté aux communautés des thaïs aux villages de Phu Mau 1 et 2 de la commune de Chieng Yen en province Son La. / Dealing with many difficult problems of the ethnic minority groups in the Nothwest mountainous areas of Vietnam, the local and the central governments tend to adapt tourism as a way to develop economics. Although there are many theorical, scientific studies and practical projects, but the so-called community-based tourism has still been causing the great harms to the culture, society and environment of the local communities. In the context of tourism development in the ethnic minority groups of Vietnam, the purpose of this thesis is to identify a type of tourism, which could be suitable adaptation to the conditions of those groups. That type of tourism is a community-based ecotourism. After finding out the causes of unsustainable development, this thesis proposes a model of controlling community-based ecotourism that is sutainable for Thai community in Phu Mau, a popular ethnic group in the Northwest of Vietnam.

L'objectif de ce travail de thèse est le développement d'une approximation polynomiale axiale dans un solveur basé sur la Méthode des Caractéristiques. Le contexte, est celui de la solution stationnaire de l'équation de transport des neutrons pour des systèmes critiques, et l'implémentation pratique a été réalisée dans le solveur "Two/three Dimensional Transport" (TDT), faisant partie du projet APOLLO3®. Un solveur MOC pour des géométries en trois dimensions a été implémenté dans ce code pendant un projet de thèse antécédent, se basant sur une approximation constante par morceaux du flux et des sources des neutrons. Les développements présentés dans la suite représentent la continuation naturelle de ce travail. Les solveurs MOC en trois dimensions sont capables de produire des résultats précis pour des géométries complexes. Bien que précis, le coût computationnel associé à ce type de solveur est très important. Une représentation polynomiale en direction axiale du flux angulaire des neutrons a été utilisée pour réduire ce coût computationnel.Le travail réalisé pendant cette thèse peut être considéré comme divisé en trois parties: transport, accélération et autres. La première partie est constituée par l'implémentation de l'approximation polynomiale choisie dans les équations de transmission et de bilan typiques de la Méthode des Caractéristiques. Cette partie a aussi été caractérisée par le calcul d'une série de coefficients numériques qui se sont révélés nécessaires afin d'obtenir un algorithme stable. Pendant la deuxième partie, on a modifié et implémenté la solution des équations de la méthode d'accélération DPN. Cette méthode était déjà utilisée pour l'accélération et des itérations internes et externes dans TDT pour les solveurs deux et trois dimensionnels avec l'approximation des flux plat, quand ce travail a commencé. L'introduction d'une approximation polynomiale a demandé plusieurs développements numériques regardant la méthode d'accélération. Dans la dernière partie de ce travail on a recherché des solutions pour un mélange de différents problèmes liés aux premières deux parties. En premier lieux, on a eu à faire avec des instabilités numériques associées à une discrétisation spatiale ou angulaire pas suffisamment précise, soit pour la partie transport que pour la partie d'accélération. Ensuite, on a essayé d'utiliser différentes méthodes pour réduire l'empreinte mémoire des coefficients d'accélération. L'approche qu'on a finalement choisie se base sur une régression non-linéaire au sens des moindres carrés de la dépendance en fonction des sections efficaces typique de ces coefficients. L'approche standard consiste dans le stockage d'une série de coefficients pour chaque groupe d'énergie. La méthode de régression permet de remplacer cette information avec une série de coefficients calculés pendant la régression qui sont utilisés pour reconstruire les matrices d'accélération au cours des itérations. Cette procédure ajoute un certain coût computationnel à la méthode, mais nous pensons que la réduction de la mémoire rende ce surcoût acceptable.En conclusion, le travail réalisé a été concentré sur l'application d'une simple approximation polynomiale avec l'objectif de réduire le coût computationnel et l'empreinte mémoire associées à un solveur basée sur la Méthodes des Caractéristiques qui est utilisé pour calculer le flux neutroniques pour des géométries à trois dimensions extrudées. Même si cela ne constitue pas une amélioration radicale des performances, l'approximation d'ordre supérieur qu'on a introduit permet une réduction en termes de mémoire et de temps de calcul d'un facteur compris entre 2 et 5, selon le cas. Nous pensons que ces résultats constitueront une base fertile pour des futures améliorations. / The purpose of this PhD is the implementation of an axial polynomial approximation in a three-dimensional Method Of Characteristics (MOC) based solver. The context of the work is the solution of the steady state Neutron Transport Equation for critical systems, and the practical implementation has been realized in the Two/three Dimensional Transport (TDT) solver, as a part of the APOLLO3® project. A three-dimensional MOC solver for 3D extruded geometries has been implemented in this code during a previous PhD project, relying on a piecewise constant approximation for the neutrons fluxes and sources. The developments presented in the following represent the natural continuation of this work. Three-dimensional neutron transport MOC solvers are able to produce accurate results for complex geometries. However accurate, the computational cost associated to this kind of solvers is very important. An axial polynomial representation of the neutron angular fluxes has been used to lighten this computational burden.The work realized during this PhD can be considered divided in three major parts: transport, acceleration and others. The first part is constituted by the implementation of the chosen polynomial approximation in the transmission and balance equations typical of the Method Of Characteristics. This part was also characterized by the computation of a set of numerical coefficients which revealed to be necessary in order to obtain a stable algorithm. During the second part, we modified and implemented the solution of the equations of the DPN synthetic acceleration. This method was already used for the acceleration of both inners and outers iteration in TDT for the two and three dimensional solvers at the beginning of this work. The introduction of a polynomial approximation required several equations manipulations and associated numerical developments. In the last part of this work we have looked for the solutions of a mixture of different issues associated to the first two parts. Firstly, we had to deal with some numerical instabilities associated to a poor numerical spatial or angular discretization, both for the transport and for the acceleration methods. Secondly, we tried different methods to reduce the memory footprint of the acceleration coefficients. The approach that we have eventually chosen relies on a non-linear least square fitting of the cross sections dependence of such coefficients. The default approach consists in storing one set of coefficients per each energy group. The fit method allows replacing this information with a set of coefficients computed during the regression procedure that are used to re-construct the acceleration matrices on-the-fly. This procedure of course adds some computational cost to the method, but we believe that the reduction in terms of memory makes it worth it.In conclusion, the work realized has focused on applying a simple polynomial approximation in order to reduce the computational cost and memory footprint associated to a Method Of Characteristics solver used to compute the neutron fluxes in three dimensional extruded geometries. Even if this does not a constitute a radical improvement, the high order approximation that we have introduced allows a reduction in terms of memory and computational times of a factor between 2 and 5, depending on the case. We think that these results will constitute a fertile base for further improvements.

1 Abstract: The division of state authority ilustrated on the example of the Czech Republic and French Republic with the focus on the position of the head of the state Key words: separation of state authority, constitutional laws, the legislative, the executive, the judiciary, the head of state, presidential system, parliamentary system Abstrackt: This thesis addresses the historical separation of state authority which is illustrated on the example of the Czech Republic and French Republic, especially on the position of the head of the state. The goal is to identify the identical and differing characteristics of the presidential status of both republics. The thesis is divided into three chapters and into a sub-chapters. The first chapter explains the development of the decomposition of the state authority from the first theoretical thoughts to the practical incorporation into the political system. The Second chapter describes in separate sub-chapters, the division of the state authority in Czech Republic and France. Third chapter is dedicated to the position, mandate, election and the competencies of the head of the state in both countries. Subsequently the gathered information is summarized in a sub-chapter, where the identical and differing characteristics of both presidential functions is discussed.

This study focuses on use of foreign-policy power by Georgia on USA, EU member states and Russia during 2004-2012. In this period, Georgia wanted to enter into alliance with USA and EU states and gain access to Euro-Atlantic organizations, European Union and NATO. At the same time, Georgia wanted to reduce Russian influence on Georgian soil. After a few months of the new Georgian regime it was clear that the relation with its big neighbor will be difficult, mainly because of the two separatist republics on Georgian-Russian border, Abkhazia and South Ossetia. The aim of this study is to determine categories of power that Georgia used to achieve its goals. The study uses concepts of small state and power in international relations. Besides, it uses Nye's concept of soft and hard power. For influencing Western states Georgia chose the combination of soft and hard power. Soft power of Georgia has been mainly based on presentation of attractive values - pro-Western thinking a democracy - which should have attracted Western support. To a lower extent, foreign policy and culture were also used as sources of soft power. Georgia's hard power consisted of security importance and economic and political value of the country. In case of Russia, Georgia used only tools of hard power which included harsh rhetoric...
