Changes of selected surface water geochemistry parameters in relation to rainfall-runoff regime
Bartůšek, Adam ; Matoušková, Milada (advisor) ; Havlíková, Petra (referee)
This work deals with the study of changes in the geochemistry of surface waters in relation to the rainfall-runoff regime and its transformation. As rainfall-runoff extremes such as long episodes of drought with low flows or, conversely, high flows caused by extreme rainfall events have been increasing in recent years, it is important to understand how these phenomena affect water quality. Therefore, the main objectives of this work are firstly a literature search on the changes in surface water geochemistry during change of climate and precipitation-runoff regime and methods that can be used to quantify these changes, and then the application of some of these methods to the analysis of selected parameters and their changes in the Klíčava catchment. In addition to some climatic characteristics and flow rates, the analysis included basic parameters of geochemistry (flow rate, water temperature), physicochemical parameters (electrolytic conductivity, pH), some nutrients (forms of nitrogen and phosporus) and indicators of organic pollution and stream cleanliness (BOD5, CODCr, TOC and dissolved oxygen). In addition, the status and evolution of concentrations of some herbicide metabolites were briefly assessed. For data analysis, e.g. box plots, Mann-Kendall test, correlation coefficients or linear...

Countries' Representation in Professional Staff of the World Health Organization
Slámková, Eliška ; Parízek, Michal (advisor) ; Tesař, Jakub (referee)
My thesis is focused on the composition and countries' representation in the professional staff of the World Health Organization. The thesis will analyse the overrepresentation and underrepresentation of the WHO's member states and explain possible patterns in the staff. The thesis will focus on the relationship between the number of Member State's professional staff in the WHO and the state's GDP growth, expenditure on education and population size. My thesis aims to research the characteristics of staff's composition in the WHO. I will analyse professional staff structure and apply the Principal-Agent theoretical framework. The research will show how the state's representation of member states changed over time and see also the gender composition of the Secretariat. The timeline of this work is from 1999 till 2019. The thesis works with official documents from human resources of the WHO and datasets of the World Bank. Analysis of data is provided by the statistical programme SPSS and Microsoft Excel. Key words World Health Organization, representation, professional staff, principal-agent theory, correlation coefficients, regression analysis
