Solid speciation of metals in tropical soils highly polluted by copper metallurgy
Kovářová, Lucie ; Ettler, Vojtěch (advisor) ; Vítková, Martina (referee)
Six soil samples corresponding to selected horizons (both topsoil and subsurface layers) from the forested and unforested soil profiles located in the vicinity of Mufulira Cu-Co smelter in the Copperbelt Province (Zambia) were investigated, in order to describe binding of main metal contaminants (Cu, Co, Pb, Zn) to soil constituents with a special emphasis on solid phase speciation. Sequential extraction procedure (SEP), X-ray diffraction (XRD) and scanning electron microscopy coupled to energy dispersion spectrometry (SEM/EDS) were used in this study. The highest bulk concentrations were found in soil samples from grassland areas located 3.6 and 8 kilometers from the smelter (Cu: 12 600 mg/kg, Co: 42.4 mg/kg, Pb: 40.6 mg/kg, Zn: 65.2 mg/kg). Copper was found to be the most mobile contaminant, also present in elevated concentrations in the subsurface soil layers of highly contaminated profiles, with substantial amount bound in the exchangable chemical fraction (19.3-25 mg/kg, 21-30 % of bulk Cu concentration). Besides the presence of lithogenic minerals, anthropogenic phases originating from mining and smelting activities were also observed in the heavy mineral soil fraction. These anthropogenic particles enriched in Cu or Co were identified by SEM/EDS as Cu-(Fe) oxides or sulphides of variable...

Conatimanation of vineyards soils by Cu
Kovářová, Lucie ; Mihaljevič, Martin (advisor) ; Komárek, Michael (referee)
The aim of this bachelor thesis is to resume existing knowledge regarding the contamination of vineyard soils with copper, which is mainly caused by a long-term application of Cu-based fungicides used to control wine downy mildew (Plasmopara viticola). The role of Cu as a trace element in the natural environment is discussed, as well as natural Cu contents in soils and in the Earth's crust. This manuscript is based on international scientific articles focusing on the above mentioned subject. The thesis discusses the problems of contamination of vineyard soils by Cu, deposition of Cu compounds into the soils, interaction of Cu with soil components and possible formation of mobile or immobile Cu soil forms, their behavior and factors influencing this behavior and possible environmental risks e.g. phytotoxicity, contamination of water bodies or contamination of fluvial sediments. Additionally, average Cu contents in agricultural soils in Europe and worldwide were compared with European and international guidelines and limits. Total Cu contents in some of the vineyards soils exceed legislative regulations and in case of further utilization of such soils, an additional analysis would be necessary. Key words: contamination, copper, vineyard soils, heavy metals

Jörg Haider and Austria Far Right
Kovářová, Lucie ; Charvát, Jan (advisor) ; Jeřábek, Martin (referee)
The barcherlor thesis "Jörg Haider and austrian far right " deals with the assumptions of political success of Jörg Haider as the leader of Austrian Freedom Party. From 1986 when Haider was elected as chairman to 2000 when the FPÖ became the member of coalition, the election result has been increased from 9,7% to 26,9%. In order to undestand this changing of voter's preferences are concidered the theories of far right and populism. This thesis discusses the assumptions of the political potential for increasing election results of the far right in Austria. There are concidered the facts how has the Austrian society been changed in the last half of the century including the general development in the Western Europe involving the theory of the sillent counter-revolution. There is analysed the role of Haider as the charimatic leader and the development of the austrian far right after his death and points out the topics of continuing populism.

Legal Aspects of Consumer Credit Protection
Kovářová, Lucie ; Švestka, Jiří (referee) ; Salač, Josef (referee)
The main aim of the thesis is to analyze present legal regulations of consumer credit with respect to the present practice of courts and the practice of credit providers. For this purpose I use the analytical method, the descriptive method and the comparative method. The thesis itself is divided into nine closely related parts. The beginning of my thesis deals with general questions. The first chapter gives general comment on credits. The second chapter focuses on the most important legal rules related to the topic. This is especially The Commercial Code, The Civil Code and the laws on consumer credit. The section 262, subsection 4 of The Commercial Code is of the particular importance. The chapter three looks at the implementation of the Directive 2008/48/ES, which has been adopted in the Czech environment as the law on consumer credit (145/2010 Coll.). This law will replace from the 1st January 2011 the law 321/2001 Coll. which regulates the consumer credit nowadays. The main part of the thesis is focused on the process of entering into the contract and the necessary requirements which are imposed on the contracts by the Commercial Code and by the laws on consumer credit: 145/2010 Coll. and 321/2001 Coll. The chapter five deals with the means of security. The emphasis is put on practical...

Education and human resources development in selected companies
KOVÁŘOVÁ, Lucie
The aim of the diploma thesis called "Education and human resources development in selected companies" is to highlight the prevalent forms of education in selected companies, to analyze them with regard to human resources development and to propose changes leading to improve the future knowledge economy. Two companies have been selected for research: Schwan Cosmetics CR, Ltd., based in Český Krumlov, which produces wooden cosmetic pencils, and Leifheit, Ltd., based in Blatná, producing domestic utensils and fabrics. The thesis is divided into a theoretical and an experimental part. The theoretical part required a number of relevant scholarly treatises to be studied. In this part, the basic terminology pertaining to human resource management, education of employees and knowledge economy is explained. The following part first describes the selected companies and then it focuses on the analysis of education of employees and the human resources development in these companies, by means of questionnaires and unguided interviews with heads of personnel departments. In the closing part, a summary of acquired data, together with recommendations and suggestions for possible improvements are included.

Education and development of employees in a particular company
KOVÁŘOVÁ, Lucie
The objective of the bachelor thesis named Education and development of employees in a particular enterprise is to analyze the process of staff training and development, characterize and evaluate existing HR processes, identify the needs of employees and the company and suggest possible ways to improve the current situation. The thesis is divided into two parts. The first part is theoretical and deals with the interpretation of concepts related to staff training and development. Information for this section was obtained from the czech and foreign professional literature. The second part contains a detailed characterization and analysis of selected enterprise education and development through unstructured interviews. For this purpose, I chose the company Leifheit, Ltd. headquartered in Blatná. This company is engaged in manufacturing of small items for home and home textiles. Using unstructured interviews conducted with the HR department I characterized the training and development of employees in the company and carried out the analysis of the current state of education. The thesis is targeted on a particular education that took place in the organization in previous years, on the description of external companies, which Leifheit uses for education and also for the initial training, which is very important too.
