Spatial molecular ecology of the brown bear in Western Carpathians
Šrutová, Jana ; Hulva, Pavel (advisor) ; Hájková, Petra (referee)
In the current human-dominated landscape, wildlife populations are more often exposed to the island effect, loss of genetic variation and the associated risk of extinction vortex. Landscape genetics studies microevolutionary processes in populations and their relationships to landscape features. Integration of the results of genetic analyses and the results of habitat modeling of the species under study helps to identify transition zones between suitable habitats or anthropogenic barriers to gene flow in the landscape. Analysis of the spatial population structure of wildlife populations is an important tool for the conservation and management of populations. Between 2019-2021, 2172 mostly non-invasive brown bear (Ursus arctos) samples were collected in Slovakia, mostly collected in the Western Carpathian region. Using a microsatellite panel containing 10 polymorphic loci and the SRY gene for sex determination, a total of 1036 genotypes were identified, including 632 unique genotypes. The population seems to be relatively diversified and the observed heterozygosity is comparable to other demographically stable bear populations in Europe. Using STRUCTURE, a Bayesian clustering analysis was performed, which divided the population into three or four subpopulations according to the selected method. The...

Prediction of Stock Returns using Financial Statement
Hájková, Petra ; Jakubík, Petr (advisor) ; Hollmannová, Monika (referee)
This thesis should contribute to research in the area of fundamental analysis. Its aim is to study whether financial statement data of Czech non-financial companies capture information that is not reflected in prices. Therefore, the question is whether investment strategy based on financial statement analysis could earn excess returns. In order to test this hypothesis, a three-step estimation procedure based on a logit model is used to identify financial ratios relevant for prediction of future earnings. The final estimated model includes four financial ratios and is then used to set a one-year investment strategy. Although the performance of the estimated model is not too sound, this investment strategy brings positive abnormal returns during the monitored period of time. Despite the fact that results were influenced by several factors, they could indicate that financial statement analysis of companies listed on the Prague Stock Exchange is able to predict stock returns.

Problematic aspects of public tenders from the perspective of a municipality
Hájková, Petra ; Svoboda, Petr (advisor) ; Millerová, Ivana (referee)
The problematic aspects of awarding of public procurement from the perspective of the municipality. The aim of this thesis is a presentation of certain problems associated with awarding of public procurement by public authority - the municipality. This thesis is divided into three parts. The first part provides a general introduction to the topic. This part defines the basic terms and principles associated with public procurement, attention is also focused on a definition of local government units. At the beginning of the second part a legal framework of public procurement and a brief view of the future legislativ is presented. The most important section of this part describes bodies of the municipality and their competences associated with awarding of public procurement. Thereafter it deals with mistakes and shortcomings which may arise during the tender process from the part of municipalities. In this part specific situations coming from the practical experience of municipalities are described and analysed, including a list of potential impacts on municipalities. Attention is also paid to current jurisdiction and decision making practices of the Office for Protection of Competition. The final part of this thesis summarizes the conclusions drawn in the previous chapters.

Genetic structure of mammalian invasive populations on islands
Loudová, Miroslava ; Černá Bolfíková, Barbora (advisor) ; Hájková, Petra (referee)
Biological invasion is understood as introduction, establishment and expansion of organisms into new, non-native area. This is a natural process that is significantly compounded by human activities and is one of the factors that threaten biological diversity and stability of natural ecosystems. Understanding to the evolution and current status of invasive populations is especially important for planning a project to eradicate invasive species from certain areas to avoid their negative impact on the environment. One option for the research of the invasive populations and their history is the analysis of genetic material. This thesis summarizes the current knowledge on invasive populations of small mammals on the islands, with the focus on genetic studies. Specifically, the study of Norway rats (Rattus norvegicus) on Moturemu island and five archipelagos off the coast of Brittany; black rats (Rattus rattus) on Congo Cay, Madagascar, Guadeloupe Archipelago, Sainte Anne Archipelago and Canary Islands; Pacific rats (Rattus exulans) on Tetiaroa Atoll; house mice (Mus musculus) on Marion Island; house mice (Mus musculus domesticus) on Kerguelen Archipelago; red squirrels (Sciurus vulgaris) on Jersey island, West European hedgehogs (Erinaceus europaeus) in New Zealand; pygmy shrews (Sorex minutus) in Ireland and...

Procedural requirements of civil proceedings and examination thereof
Hájková, Petra ; Frintová, Dita (advisor) ; Sedláček, Miroslav (referee)
Procedural requirements of civil proceedings and examination thereof Abstract The main purpose of the submitted thesis is to provide a comprehensive treatise on procedural requirements of civil proceedings and examination thereof, as well as on addressing the deficiencies of procedural requirements identified during the proceedings and consequences arising in the event of failure to adress such deficiencies. The aim of this thesis is to present and analyse not only the requisites of civil proceedings, which are expressly identified as procedural requirements by the Code of Civil Procedure, but also such requisites regarding their classification as procedural requirements the professional public has not reached the consensus. The thesis is structured into five parts, then into chapters and subchapters. The first part of the thesis concentrate primarily on the definition of the concept of procedural requirements and the differentiation of deficiencies of procedural requirements from defects in the document instituting the proceedings. The second part is devoted to detailed description of the procedural requirements on the part of the court, namely the civil competence and jurisdiction of the court. The third part describes the procedural requirements on the part of the participants, ie the procedural...

Non-invasive conservation genetics of ursids
Šrutová, Jana ; Hulva, Pavel (advisor) ; Hájková, Petra (referee)
This bachelor thesis is devoted to non-invasive genetics and molecular ecology of particular species of ursids(family Ursidae). This carnivore lineage is quite diversified, particular species inhabit different environments from arctic regions to tropical rainforests and they also differ in trophic niches. As remnants of megafaunal communities that occupy important positions in ecological networks, they are often referred as keystone, umbrella and flagship species which are important in conservation biology. During the Anthropocene, the existence of particular species of Ursidae is more or less influenced by human activities or their impacts. Although nature conservation has managed to stabilize the abundance of some species, habitat loss and human- bear conflicts are becoming more frequent as a consequence of the expanding human population. The aim of the work was to review the research of population structure and demography especially using non-invasive genetic techniques in particular species with intention to implement the acquired knowledge into brown bear research in the Western Carpathians in the future. The chapter about non-invasive sampling is focused to this model species. Non-invasive genetics is important tool for research especially in large, rare, highly mobile and elusive species and...
