The rapid development of space geodesy over the last two decades has had a profound effect on geologic studies by allowing measurements of crustal motion with sub-millimeter per year precision. The focus of this work is to better understand microplate kinematics, intraplate deformation and sea level rise in Europe by use of Global Positioning System (GPS) measurements of crustal deformation. This is accomplished in three separate studies. The first study focuses on crustal motion and sea level rise along the eastern margin of Adria. We use data from tide gauge and continuous GPS (CGPS) stations. We develop a new method to separate common-mode relative sea level from spatially variable signals. From tide gauge data, we find uniform relative sea level rise along the coast that is 2-4 times lower than the estimates for global average sea level rise. In constrast, vertical motion of coastal rocks determined by CGPS varies appreciably from an average of -1.7 ± 0.4 mm/yr in the southern Adria to 0.0 ± 0.4 mm/yr in northern Adria. The most enigmnatical result of this study is that the combination of tide gauge and CGPS data shows that absolute sea level varies in such a way that relative sea level remains constant. The second study focuses on diffuse intraplate deformation of western Eurasia measured by CGPS. We find that our preferred model involves four subplates, separated by the Pyrenees, Rhine Graben, and Trans European Suture Zone, and yields residual velocities indistinguishable from random samples. We interpret the intraplate dormation as the surface manifestation of downwelling mantle lithosphere. The final component of this work is a study of the Northern and Southern Adria microplates' internal stability and tectonic motion. Results show that both Adria microplates are kinematically distinct from one another and from the slowly converging Eurasia and Nubia plates, with implications for the dynamics of the Nubia-Eurasia plate boundary zone. We also find that internal strain within the Adria microplates is statistically insignificant. We estimate appreciable fault slip rates around the periphery of Adria, with implications for slip rates and seismic hazards associated with circum-Adria fault zones.

Au Nord-Est de la microplaque Adriatique la jonction Alpes-Dinarides représente une région clé pour comprendre les interactions entre la microplaque et l’Europe stable. Alors que la tectonique active de la partie alpine de cette zone est relativement bien contrainte, peu de données sont disponibles quant aux déformations actives contrôlées par la rotation de la microplaque à travers les Dinarides. Par une approche morpho-tectonique (étude de terrain combinée à l’analyse d’images aériennes et satellitaires, de cartes topographiques et modèles numériques de terrain haute résolution) nous avons cartographié en détails les failles actives des Dinarides septentrionales et de la partie orientale des Alpes du Sud. Sur la base de cette cartographie et des données géologiques une quarantaine de décalages tectoniques cumulés allant de quelques mètres à plusieurs kilomètres a été identifiée. A l’aide de datations 36Cl de marqueurs morphologiques affectés par les failles combinées aux chronologies existantes les vitesses de déformation actuelles ont ensuite été estimées. L’évolution des déformations depuis le Pliocène a pu être contrainte dans les Dinarides mettant en évidence une initiation des failles au début du Pliocène et un changement cinématique important autour du Pléistocène moyen. Les vitesses obtenues, notamment environ 3mm/an de mouvement dextre le long des Dinarides, ont finalement été confrontées aux modèles existants ce qui a conduit à proposer un modèle cinématique décrivant l’accommodation de la rotation de l’Adriatique par le mouvement relatif de blocs lithosphériques rigides et qui permet d’expliquer les déformations actives observées aux frontières de ces blocs. / At the northeastern corner of the Adria microplate the Alps-Dinarides junction represents a key region to understand the interactions between the microplate and the stable Europe. While the active tectonics of the alpine part of the area is relatively well-known, few data allow characterizing the present-day deformations controlled by the microplate rotation across the Dinarides. Using a morpho-tectonic approach (field study combined to the analysis of aerial and satellite images, topographical maps and high-resolution digital elevation models) we mapped in details the active faults in the Northern Dinarides and the eastern part of the Southern Alps. Based on this mapping and geologic data forty tectonic cumulative displacements ranging from few meters to several kilometers have been identified. By determining the 36Cl exposure ages of faulted geomorphic markers and comparing it to existing chronologies the present-day rates of deformation have then been assessed. The evolution of the deformations since the Pliocene could also have been constrained revealing an Early Pliocene age for the onset of strike-slip faulting and a major kinematic change during the Middle Pleistocene. Finally the yielded faults slip-rates, especially about 3 mm/yr of right-lateral motion across the Dinarides, have been compared to existing models. That allowed proposing a kinematic model describing the Adria rotation accommodation through the relative motion of rigid lithospheric blocks and explaining the observed active deformations at their boundaries.

Organizational culture is very important determinant of every organization. This diploma thesis deals with the specific aspects of organizational culture. It consists of four main parts. In the first chapter the theoretical basis regarding organizational culture, organizational commitment and experiential education is described. The second part consists of the deep analyses of hotel Adria Prague. It provides the information regarding its employees, clients, competition and specific events the management organizes on regular basis. The next part is dedicated to the empirical research the aim of which was to identify organizational strategy and values as well as the extent to which employees identify with these values. It also focuses on factors fostering organizational commitment. In the final part of the thesis the practical recommendations for the management of the hotel are mentioned.

Master thesis "Czech Republic and its connection to new LNG terminals - strengthening of the gas security" examines the level of gas security in the Czech Republic. Dependency of the Czech Republic on gas supplies from foreign countries is almost 100 %. Russian federation is dominant supplier with roughly 75 % of the supplies. High dependency on one exporter is considered hazardous from energy security perspective. The Czech government should strive to change and improve this situation. The diversification is considered as a useful tool to improve the gas security. Currently there are new gas projects built in neighboring countries, which may influence energy security of the Czech Republic. The study researches the impact of these new projects on the Czech Republic. Namely we focused on gas pipeline Nord Stream and its Czech connection Gazelle, which will connect North Germany and Bavaria through the Czech Republic. Second project is gas network called "the North - South Corridor" connecting Baltic and Adriatic Sea. The North - South corridor may be potentially linked up to the new LNG terminals Świnoujście in Poland or Adria in Croatia. Furthermore, there are long-lasting plans to open new "South" gas route from Caspian region to Europe. The main goal of this thesis is to explore real...
