System Management Model of a Professional Service Firm
Hubík, Tomáš ; Křivánek, Mirko (advisor) ; Majerech, Vladan (referee)
In the presented work I devote to creating a computer model of a professional service firm using the theory of business modeling. The whole model was programmed using the application Vensim. Another part of this work was to use this model to answer some key questions about the professional service firms. I dealt with the issue of optimal volume and optimal size of potential orders. I have also studied the influence of marketing and employee productivity on business performance. Another part of the work was to find patterns in employees career growth and to monitor sales and quality of projects delivery. I also determined the size and characteristics of critical mass. Such a model could then be used to better understand patterns of companies in the professional services industry and we can use it to manage the company more effectively in this environment.

The development of tax collection from personal income tax in the Czech Republic
Šubová, Lucie ; Láchová, Lenka (advisor) ; Kouba, Tomáš (referee)
This diploma thesis analyses the development of tax collection from personal income tax in the Czech Republic from 2000 to 2012. The first chapter describes the tax reforms that took place in the period in the Czech Republic. Furthermore, it describes the relationship of collection and GDP. In the second chapter I analyse the PIT collection as whole. By regression and correlation analysis I shall identify the relationship and the degree of dependence between collection and different variables such as GDP, the number of taxpayers, unemployment and sub-collections. In the third chapter, the PIT collection is divided into three sub-collections -- levied on tax returns, from employment and withholding. Each of the sub-collection is analysed separately. I describe factors that in a given year or in group of years the most influenced their size. By regression and correlation analysis I shall identify the relationship and the degree of dependence between the sub-collections and GDP. Likewise, I shall identify the relationship and the degree of dependence between the sub-collections each other. In the last chapter the PIT collection is divided by individual financial authorities, ie by region. The development of tax collection in each region is analysed and by regression and correlation analysis is detected the relationship and the degree of dependence between the regional collections and GDP.

Vliv životního cyklu organizace a socio-ekonomické charakteristiky země na charakteristiku vrcholového managementu
Velinov, Emil Iordanov ; Malý, Milan (advisor) ; Špaček, Miroslav (referee) ; Hučka, Miroslav (referee)
The dissertation examines the impact of Organizational Life Cycle (OLC) and the Country Socio Economic Characteristics (CSEC) on Top Management Team (TMT) Characteristics. The dissertation first elaborates and establishes the theoretical link between Organization Life Cycle, Country Socio-Economic Characteristics and characteristics of TMT. Second, a quantitative empirical study is conducted to test the OLC phases and CSEC impact on the TMT characteristics through characteristics. The dissertation outlines a detailed research methodology based on the state-of-art in the area of OLC, TMT and CSEC that will be implemented to answer the key research questions in regards to the scope of the doctoral thesis. Data set is collected from the 300 largest Swiss, German and Czech companies at year-end 2011, including detailed data on the country socio economic characteristics and career backgrounds of all TMT members (executive boards) at these companies at the end of 2011. A detailed procedure is developed to accurately classify organizations at different lifecycle phases, drawing extensively on existing literature and scales. Multilevel data analysis techniques are employed to understand how the different organization lifecycle phases influence both the level of TMT characteristics as well as changes in TMT composition and diversity due to inbound and outbound mobility of top managers over time. Substantial research synergies and knowledge transfer effects expected to emanate from this dissertation. In the dissertation regression and correlation analysis are applied for each phase of the companies' OLC in Switzerland, Germany and the Czech Republic. The dissertation states that more mature the company is more diversified the TMT are regardless the country. Also, the country impact has its own role in the relationship between the OLC and TMT characteristics which is expressed by the findings that Switzerland and Germany are more diversified than the Czech Republic in terms of TMT characteristics as gender diversity, age diversity, nationality diversity, education background of the TMTs, TMT dominant functions and TMT career length. The doctoral thesis contributes to the research by revealing relationships between TMT, CSEC and OLC theories. Also it develops methods and techniques for finding the interconnections between the OLC phases, CSEC with the TMT characteristics and the dissertation outlines the future research gaps in the area of TMT.

Growth and survival of pearl mussel (Margaritifera margaritifera) for bioindication
NIEDLOVÁ, Eva
Growth and survival of juvenile pearl mussels (Margaritifera margaritifera Linnaeus, 1758) "in-situ" indicates suitable habitats for their rearing and subsequent reintroduction. Six streams in Aš region (Rokytnice, Lužní potok, Pekelský potok, Újezdský potok, Perlový potok, Bockbach) including 15 profiles were evaluated throughout the season (1. 6. 31. 8. 2015). One year old pearl mussels (n = 580) sized from 700 1400 ?m. Mean survival of pearl mussels was 63 % in all streams. Mean absolute growth increment attained 755 ?m throughout the season. Growth of pearl mussels (1+) was positively correlated with the water temperature (R2 = 0,1084). Both the highest survival (70 %) and the highest absolute growth (1027 ?m and 997 ?m) of pearl mussels was determined on localities in Bockbach (Bockbach 11 and 1). In contrast to Bockbach 11 and 1 mean survival (28%) and absolute growth (304 ?m) was the lowest in Lužní potok 2. Survival rate of two years old pearl mussels was higher than that of one year old pearl mussels. Both of these age categories grew similarly.

Neurofibromatosis type 1 and NF1 germline mutations in Czech patients
Bendová, Šárka ; Křepelová, Anna (advisor) ; Kleibl, Zdeněk (referee) ; Kadlecová, Jitka (referee)
Neurofibromatosis type 1 (NF1, MIM 162200) is an autosomal dominant disorder affecting about 1 of 3000 live births, involving many cell types and organs, and associated with an increased risk of malignancy, predominantly of the central and peripheral nervous system 1. Tumour development is caused by inactivation of the NF1 tumour suppressor gene and subsequent cell cycle deregulation 2. Mutational analysis of NF1 is a challenge due to the presence of pseudogenes, large size of the gene, lack of mutational hotspots, and occurrence of a very diverse spectrum of mutations. There is no clear-cut genotype-phenotype correlation allowing accurate prediction of severity of the disorder. Only two mutations have been associated with a particular NF1 phenotype 3,4. This PhD thesis is composed of six publications dealing with NF1. Publications 1 and 6 are focused on NF1 mutation analysis in 67 patients from the Czech Republic. Genotypes and spectra of causal mutations are presented together with phenotypes of the patients and comparison of efficiency of various methods. Sporadic or familial cases with known germline mutation were distinguished by mutational analysis of other family members. This led to a hypothesis that the incidence of sporadic cases could had been overestimated in the past because of overlooked...
