S ohledem na skutečnost, že více než polovina uskutečněných fúzí a akvizic je považována za neúspěšnou, realizovala jsem výzkum, který sleduje proces fúzí a akvizic v České republice a hodnotí jejich úspěšnost s ohledem na vývoj odvětví. Ve své disertační práci se zabývám vývojem fúzí a akvizic uskutečněných českými subjekty od roku 1997 až do 1. poloviny roku 2008 a hodnotím tento vývoj z několika hledisek tak, abych mohla posoudit úspěšnost transakčního procesu českých podnikatelských subjektů. Dospěla jsem k závěru, že akviziční společnosti mají před i po akvizici většinou velmi dobré finanční výsledky. Fúzované společnosti jsou naopak v době transakce pod průměrem České republiky, avšak v po transakčním vývoji se jejich finanční výsledky vyvíjejí ve srovnání s odvětvím velmi pozitivně. I když je potřeba zohlednit individuální charakter každé transakce, konstatuji, že v období 1997 až 2007 převažovaly v České republice úspěšné fúze a akvizice. Další závěry: - Transakční aktivita na území České republiky vykazuje klesající trend. - Nejčastěji probíhají fúze a akvizice mezi českými společnostmi navzájem. České společnosti nejčastěji kupují ze zahraničních subjektů slovenské společnosti. Naopak české společnosti jsou předmětem zájmu německých a amerických společností. - Některá průmyslová odvětví zaznamenávají klesající trend zájmu o transakce. - Hodnota transakce v období 1997 až 1. polovina roku 2008 v České republice klesá. - Nejčastějším způsobem úhrady kupovaného podílu je hotovost. - Nejčastěji se kupují společnosti, kde lze získat stoprocentní podíl nebo alespoň majoritu.

Using one's success and failure experiences can be an indicator of how well risk is being managed in uncertain situations, particularly because exact probability information about outcomes is often missing. Experience-based paradigms include this more real-world aspect of a lack of information when studying risk taking behavior. This thesis builds upon experience-based paradigms to include the element of skill. A puzzle task was developed. A goal was given to participants to try to discern a pattern in each puzzle that would yield consistently positive outcomes. Participants were randomly assigned to a high or low success rate, but told that skill played a role in performance. The outcomes associated with each puzzle were chosen by the participant, and served as a measure of risk taking. After playing 41 puzzles, participants responded to scales measuring skill and chance beliefs, and motivational focus. Risk preferences were similar to experience-based paradigm predictions, though they were not well-calibrated. Those with a high success rate took more risks relative to those with a low success rate, but the results were less extreme than predicted. In addition, a closer look revealed that the pattern for those with a low success rate began by increasing their risk taking, and then did not decrease their risk taking significantly. Neither group felt that skill or chance was playing a dominant role in outcomes, though self-serving bias was observed as better performance did lead to higher ratings of skill. Overall, the results suggest that introducing the potential for skill may change how people approach risk in ways not predicted by experience-based paradigms.

Position of small and medium companies in the information technology sector plays important role in the functioning on any state's economy. Focusing on a specific local market and using the Czech Republic as a case study, one has to state that most Czech firms face difficulties when trying to achieve economic success. Based on this fact, small and medium enterprise rating seems to be appropriate approach to determine factors that influence their performance and thus the possibility to help with their situation. Aim of this Master thesis is to determine these factors and construct econometric success rate models. Questionnaire research among ICT enterprises, and further statistical analysis showed that the earnings- employee ratio, average revenues and the R&D importance ratio plays the most important role in their success. Both, financial and non-financial indicators perform significantly in these predictions. Bibliographic record Krejčí, M. (2013): Factors that influence the success of small and medium enterprises.

Title: Analysis of the elite tennis players for the selected match Objectives: The aim of the work was to find out the frequency, effectiveness and success of the elite players in the selected French Open 2018 match. This was the final match of this tournament, where i analyzed every forehand. Methods: The analysis was done by observing video recordings of final matches from the French Open 2018. This was a notation analysis. The results were recorded in pre-created tables and then converted to charts. Results: The results show us which player has used the forhend, where the forhend was more successful, more efficient, and in which direction it was played. Keywords: forehand, frequency, efficiency, success rate

Title: The effect of the place of the match on the shooting success in handball. Objectives: The main objective of this work is to find out whether the place where the match is taking place affects the shooting success from individual player areas, and also the overall shooting success of the selected team. Another objective was to find out whether the place has got an effect on the result of the match. Methods: For data collection we used the methods of direct observation, indirect observation and analytical method in our work. The results were processed using the Mann Whitney test, Wilcoxon test and Mc Nemar test. Results: We found out that the place at which the match is taking place does not affect the overall percentage success rate of shooting of the selected team. Also it was not statistically proved, that the place affects the percentage success rate of shooting even from one of the basic areas of player functions for the attack. Keywords: handball, shooting, percentage success rate, place, game performance

O objetivo desse estudo foi avaliar a relação entre o grau de severidade da má oclusão de Classe II e o sucesso do tratamento sem extração desses pacientes. A amostra se constituiu de 277 pacientes que apresentavam inicialmente má oclusão de Classe II, de ambos os sexos, nas fases de dentadura mista tardia ou permanente que foram tratados ortodonticamente sem extração. Os pacientes foram divididos em 2 grupos. O grupo 1 constituído por pacientes que apresentavam má oclusão de ½ Classe II. O grupo 2 constituído por pacientes que apresentavam má oclusão de Classe II completa. Estes pacientes foram selecionados em caráter retrospectivo, verificando-se todo o arquivo da Disciplina de Ortodontia da Faculdade de Odontologia de Bauru - USP. O Índice de Prioridade de Tratamento (IPT) foi utilizado para verificar a severidade inicial da má oclusão assim como os resultados oclusais ao final do tratamento de cada paciente. As médias dos escores iniciais e finais do IPT foram comparadas entre os grupos pelo teste t não pareado. O índice de eficiência foi calculado pela proporção entre a porcentagem de melhora pelo tempo de duração do tratamento. Os resultados mostraram uma diferença significante entre os grupos. Houve maior proporção de sucesso do tratamento ortodôntico sem extrações da má oclusão de ½ Classe II em comparação à Classe II completa. O tempo do tratamento ortodôntico foi maior nos pacientes que apresentavam inicialmente ao tratamento, uma Classe II completa. O índice de eficiência do tratamento foi maior em pacientes com menor severidade inicial da má oclusão de Classe II. / The purpose of this study was to evaluate the treatment success rate of Class II malocclusion without extractions, according to initial severity. Class II subjects were divided into 2 groups according to the severity of the malocclusion. Group 1 comprised 144 patients with bilateral half Class II malocclusion at the initial mean age of 12.27 years. Group 2 comprised 132 patients who initially had bilateral complete Class II malocclusion at the initial mean age of 12.32 years. The patients initial and final study models were evaluated with Graingers treatment priority index. Chi-square tests were used to test for differences between the 2 groups for categorical variables. Variables regarding occlusal results were compared with independent t tests. Group 1 had a significantly better final occlusal result, a shorter treatment time, and a higher treatment efficiency index. Based on these results, it was concluded that bilateral half Class II malocclusion has a better treatment success rate than bilateral complete Class II malocclusion when treatment is conducted without extractions

Time Memory Trade O (TMTO) is a cryptanalytic method that aims to develop an attack which has a lower memory complexity than lookup table and a lower online time complexity than exhaustive search. TMTO methods are widely studied in the literature and used for inverting various cryptosystems. We focus on the design and the analysis of TMTO on symmetric ciphers in this thesis. Firstly, the summary of the random mapping statistics from the view point of TMTO is presented. We also recalculate some expected values with a simpler approach than the existing proofs. Then, we propose some variant constructions and also present three new distinguishers based on random mappings. Next, we provide a detailed analysis of the success rate of two main improvements of the attack / Distinguished Point Method and Rainbow Method. Finally, we discuss the adjustment of the parameters to achieve a high success rate. To support our theoretical framework, we also present empirical results of our analysis to actual ciphers.
