This thesis analyzes gamble gaming, bets and lottery in the Czech Republic. Historic context of hazzard and view of economic theory and the game theory is described in details. This thesis deals with the economic, social and legislative impacts of gamble gaming and bets. Current changes and issues are analyzed in depth, there are also views of the particular subjects included within this analyze. The thesis proves via argumentation the inadequacy of the current legislative framework in the field of gambling and predicts what possible consequences the extensive legislative changes may bring. The Thesis studies the approach of former works dealing with the subject and methods of hazzard social expenses quantification. Current environment of gambling is analyzed on the country level as well as on the municipal level (As an example town Třešť and Jihlava were chosen).

Cette thèse vise à étudier conjointement deux thèmes de recherche habituellement traités séparés par la littérature académique : les caractéristiques des directeurs généraux et l'engagement des employés au travail. La problématique peut se définir ainsi : quel est l'impact des caractéristiques des dirigeants sur leur engagement au travail ? ou autrement dit, comment les caractéristiques managériales influencent la nature et le degré d'implication des dirigeants au travail? Les dirigeants dans notre travail de recherche seront les dirigeants des banques au Liban : on va essayer de leur créer une typologie. / Organizational commitment has been studied comprehensively along with varied professional groups. The concept that commitment is essential for the apprehension of organizational and professional goals mainly in the Banking organizations has remained unexploited by researchers. The study of employee commitment should be important to Banking organizations receiving large amounts of community savings and playing an important role in the development of the economical sector as a whole.No previous studies have tackled the Lebanese bank managers’ subject in relevance to their organizational commitment and its relation with their biographical traits and their Job perforamance; therefore the study of organizational commitment will particularly be relevant to Lebanese bank managers, as those represent the leading power for the future of the Lebanese banking sector.

This study addressed the numerical modelling of flow and diffusion in packed beds of mono-sized spheres. Comprehensive research was conducted in order to implement various numerical approaches in explicit1 and implicit2 simulations of flow through packed beds of uniform spheres. It was noted from literature that the characterization of a packed bed using porosity as the only geometrical parameter is inadequate (Van Antwerpen, 2009) and is still under much deliberation due to the lack of understanding of different flow phenomena through packed beds. Explicit simulations are not only able to give insight into this lack of understanding in fluid mechanics, but can also be used to develop different flow correlations that can be implemented in implicit type simulations. The investigation into the modelling approach using STAR-CCM+®, presented a sound modelling methodology, capable of producing accurate numerical results. A new contact treatment was developed in this study that is able to model all the aspects of the contact geometry without compromising the computational resources. This study also showed, for the first time, that the LES (large eddy simulation) turbulence model was the only model capable of accurately predicting the pressure drop for low Reynolds numbers in the transition regime. The adopted modelling approach was partly validated in an extensive mesh independency test that showed an excellent agreement between the simulation and the KTA (1981) and Eisfeld and Schnitzlein (2001) correlations' predicted pressure drop values, deviating by between 0.54% and 3.45% respectively. This study also showed that explicit simulations are able to accurately model enhanced diffusion due to turbulent mixing, through packed beds. In the tortuosity study it was found that the tortuosity calculations were independent of the Reynolds number, and that the newly developed tortuosity tests were in good agreement with techniques used by Kim en Chen (2006), deviating by between 2.65% and 0.64%. The results from the TMD (thermal mixing degree) tests showed that there appears to be no explicit link between the porosity and mixing abilities of the packed beds tested, but this could be attributed to relatively small bed sizes used and the positioning and size of the warm inlet. A multi-velocity test showed that the TMD criterion is also independent of the Reynolds number. It was concluded that the results from the TMD tests indicated that more elaborate packed beds were needed to derive applicable conclusions from these type of mixing tests. The explicit BETS (braiding effect test section) simulation results confirmed the seemingly irregular temperature trends that were observed in the experimental data, deviating by between 5.44% and 2.29%. From the detail computational fluid dynamics (CFD) results it was possible to attribute these irregularities to the positioning of the thermocouples in high temperature gradient areas. The validation results obtained in the effective thermal conductivity study were in good agreement with the results of Kgame (2011) when the same fitting techniques were used, deviating by 5.1%. The results also showed that this fitting technique is highly sensitive for values of the square of the Pearson product moment correlation coefficient (RSQ) parameter and that the exclusion of the symmetry planes improved the RSQ results. It was concluded that the introduction of the new combined coefficient (CC) parameter is more suited for this type of fitting technique than using only the RSQ parameter. / Thesis (M.Ing.

On January 29-30, 2008 a squall line of thunderstorms moved through the Ohio Valley resulting in four deaths and one injury. Such events highlight the importance of accurate forecasting for public safety. Mesoscale Modeling plays an important role in any forecast of a potential squall line. The focus of this study was to examine the performance of several parameterization scheme combinations in the Weather Research and Forecasting Model version three (WRF) as they related to this event. These examinations included cloud microphysics (WRF Single-Moment 3-class, 6-class, and Goddard), cumulus parameterization (Kain-Fritsch and Bets-Miller-Janjic) and planetary boundary layer schemes (Yonsei-University and Mellor-Yamada-Janjic). A total of 12 WRF simulations were conducted for all potential scheme combinations. Data from the WRF simulations for several locations in south central Kentucky were analyzed and compared using Kentucky Mesonet observations for four locations: Bowling Green, Russellville, Murray and Liberty, KY. A fine model resolution of 1 km was used over these locations. Coarser resolutions of 3 km and 9 km were used on the outer two domains, which encompassed the Ohio and Tennessee Valleys. The model simulation performance was assessed using established statistical measures for the above four locations and by visually comparing the North American Regional Reanalysis dataset (NARR) along with modeled simulations. The most satisfactory scheme combination was the WRF Single-Moment 3-class Microphysics scheme, Kain-Fritsch cumulus parameterization scheme and Yonsei University scheme for the planetary boundary layer. The planetary boundary layer schemes were noted to have the greatest influence in determining the most satisfactory model simulations. There was limited influence from different selections of microphysics and cumulus parameterization schemes. The preferred physics parameters from these simulations were then used in six additional simulations to analyze the affect different initialization data sets have with regards to model output. Data sets used in these simulations were the Final Operational Analysis global data, North American Regional Reanalysis (3 and 6 hour) and the North American Mesoscale Model at 1, 3 and 6 hour timesteps, for a total of six simulations. More timesteps or an increase in model resolution did not materially improve the model performance.

<p>Using a social exchange perspective I develop a relationship typology based upon an organizational member’s psychological investments, or “side bets,” in his or her organization. This study thus examines, for the first time in the employee-organization exchange relationship (EOR) literature, the combined impact of perceptions that organizational members have with respect to their perceived social and economic investments in their organization. Specifically, outcomes of four unique EOR profiles are examined: “loyalist” (high social, high economic); “altruist” (high social, low economic); “captive” (low social, high economic); “mercenary” (low social, low economic). In a matched sample of 334 working professionals (167 employees matched with their corresponding supervisors), the hypotheses of this study are largely supported. Altruists are highest in their perceptions of organizational support, followed in descending order by the loyalists, mercenaries, and captives. Also as predicted, altruists are highest in affective commitment, followed in descending order by the loyalists, captives, and mercenaries. In terms of continuance commitment, contrary to prediction, loyalists have the highest levels of continuance commitment; however, as predicted, captives have higher levels than altruists and mercenaries. Altruists, as predicted, have the highest level of OCB, followed in descending order by loyalists, mercenaries, and captives. Finally, as predicted, mercenaries have the highest level of task performance followed in descending order by altruists, loyalists, and captives. Theoretical and practical considerations of these findings are discussed.</p> / Doctor of Philosophy (PhD)

Sammanfattning I mitt examensarbete har jag undersökt olika metoder för att skapa färgade mönster i fanerade ytor. Jag har med praktiska tester och metoder undersökt olika kvalitéer i olika tillvägagångssätt samt jämfört för och nackdelar med respektive teknik. I tur och ordning undersöker jag olika träslags lämplighet för ändamålet, liksom olika infärgningsmedel, fiberbrytartekniker och metoder för infärgning. Med en tillbakablick i vår möbelhistoria har jag hämtat gamla tekniker för ytdekor i möbler med fokus på färg och faner och jämfört dessa med mer utvecklade samt moderna tekniker. I min undersökning har jag vägt praktiska, tekniska samt visuella fördelar. Genom att jämföra dessa tekniker och se vilken som uppnår flest fördelar, och med uteslutningsmetoden har jag kommit fram till att den metod som ger bäst resultat är vattenbets på björkfaner med mönster bränt med laserteknik och färgen applicerad genom att använda schablon samt stämpel med syntettyg. / Abstract In my thesis project I have investigated different methods for creating colored patterns in veneered surfaces. With practical tests and methods, I have studied different qualities in different approaches as well as compared to the pros and cons of each technique. In turn, I investigate the suitability of different wood types for the purpose, as well as different materials for staining, different fiber cutting techniques and different methods of applying the staining. With a look back in our furniture history, I have collected old surface decoration techniques, focusing on color and veneer, and compared these with more developed and modern techniques. In my survey, I have weighed practical, technical and visual aspects. Comparing these techniques helped me to conclude which alternative seemed the most suitable. I have come to the conclusion that the best-performing method is water based staining on birch veneers with laser cut patterns and the color applied by using stencils and stamps made with synthetic fabrics.

The work explains the development of community income as a result of the amendment and also the development of funds spent on community purposes. Possible changes to the issue are suggested herein.

The colourful past of the late 18th century marquetry furniture has seldom been highlighted. Through ageing and environmental influences, colourful marquetry furniture has lost their original expression. The current knowledge of how Swedish cabinet-makers in the late 18th century used dyes to colour their furniture is limited. Trace of colour has been observed and the use of dyes has been mentioned, but deeper research in this filed is missing. A visual examination and studies of archive documents and previous research have been performed to investigate the colourful past of Gottlieb Iwerssons masterpiece, a secretaire in Gustavian style made for the king Gustav III. The result shows that the secretaire has a colourful past in accordance with its original drawing. A hypothetical picture has been created to illustrate the colourful original appearance.
