Enviromental Impact of Winter Olympic Games
Podloucký, Josef ; Parry Martínková, Irena (advisor) ; Kolář, František (referee)
Title: Environmental Impact of Olympic Winter Games Objectives: The objective of my bachelor thesis is to evaluate the impact of Olympic Winter Games (OWG) on the environment and vice versa. The work is divided into three parts. The first part has a goal to reflect the development of OG and of the International Olympic Committee (IOC) strategies to sustainable and ecological OWG. The second part is more of natural science account climate development and the use of technologies and their impact on nature. The last part aims to suggest several possible scenarios about future development of OWG. Methods: In the bachelor thesis basic methods of theoretical work are employed, i.e. compilation methods, analysis and synthesis. The employed methods are described in more detail in the Methodology chapter. Results: The result is a research work evaluating the IOC's attitude to climate change and environmental devastation and the impact of climate change on OWG. The evaluation was carried out on the basis of the IOC regulations and a study of expert articles on the ecological demands of winter sports. The conclusion of the thesis offers possible scenarios about the future of the Olympic Games.
The Effect of Temperature on Suicide: A Meta-Analysis
Bartušek, Daniel ; Havránková, Zuzana (advisor) ; Bajzík, Josef (referee)
In this thesis I investigate the empirical evidence on the relationship between temperature and suicide rates. The previous survey on the relationship sug- gested that a 1řC increase in temperature is associated with a 1% increase in suicide risk. An estimate of this magnitude would play a significant role in the computation of the social cost of carbon, a concept used to set climate-related regulations by policymakers around the world. I challenge this conclusion using novel, state-of-the-art meta-analysis methods. By expanding the dataset and correcting for publication bias I show that the effect of temperature on suicide rates is three times less than previously suggested, deeming the relationship economically insignificant. Moreover, I did not find any robust evidence for a specific study design that would systematically influence the magnitude of the estimated effect quantifying this relationship.

Population dynamics of cushion plant Silene acaulis in the High Tatras
Krchová, Emma ; Münzbergová, Zuzana (advisor) ; Macek, Martin (referee)
This diploma thesis is studying population dynamics of endangered species Silene acaulis in the High Tatra Mountains in Slovakia. Silene acaulis is a species of extreme alpine habitats creating cushions that provide a microclimate acting as a facilitator of establishment of other species in the alpine communities. This dome-like structure has one woody taproot making it easier to distinguish each individual. It is thus a perfect model species for determining the population dynamics drivers. The findings help in understanding future behaviour of the species and whole alpine ecosystems. Population data have been collected since 2013 or 2014 in two valleys in the High Tatras providing a database suitable to study various effects on species performance. Data collection includes marking, measuring, counting of flowers and capsules, viability and new seedlings recording, gender identification and comparison of vegetation structure within and in close proximity of a cushion. The data on vegetation were analysed using CCA ordination and the population data were analysed using Integral Projection Models. The results show that the breeding system of Slovak S. acaulis is gynodioecious and the gender affects the size of cushions, individuals with both female and hermaphrodite flowers being the biggest. The...
Impact of the Application of the Quality Management Systems on the Satisfaction of the Students of Secondary Vocational Schools
Liška, Roman ; Veteška, Jaroslav (advisor) ; Chvál, Martin (referee) ; Švec, Václav (referee)
The subject of the dissertation is the issue of school quality, resp. quality management systems used by secondary vocational schools in the Czech Republic. The use of these customer-oriented quality management systems is common abroad, in some countries even mandatory. According to the available information, these systems are not widely used in the Czech Republic, their use in the education sector is not registered. The aim of the work was to evaluate and compare the impact of the most frequently used systems (self- assessment framework CAF, EFQM and ISO standards: 9001) on the student's satisfaction and their attitudes to school. An experimental, exploratory and ex-post-factual study was carried out in 2020 using a standardized questionnaire developed by the Institute for Pedagogy and Adult Education at Leibniz Universität Hannover. The questionnaire has been used since 2011 to assess student's satisfaction and the quality of vocational secondary schools in Lower Saxony. Through factor analysis, the questionnaire was divided into three main and five sub-indices. The questionnaire was piloted on a sample of 741 respondents in a Prague secondary vocational school. The data collection itself was carried out at 21 secondary vocational schools of various sizes and founders, with the exception of one...
Population dynamics of Minuartia smejkalii
Hrušková, Karolína ; Münzbergová, Zuzana (advisor) ; Dostál, Petr (referee)
Serpentine areas in the Czech Republic form minor but important islands in the landscape with specific chemical properties such as high content of magnesium and other heavy metals. Due to this, serpentine is toxic for most plants. Increased demands on the survival and occurrence of plants lead to the emergence of serpentine specialists obligatorily specialized in these extreme habitats. Currently, serpentine areas are threatened by gradual overgrowth of sites, insufficient or poor site management and fragmentation or shrinkage of sites due to anthropogenic activities. Along with the disappearing localities, the serpentine specialists, are becoming highly endangered. Minuartia smejkalii is highly endangered serpentine specialist with an endemic occurrence in the Czech Republic with great need of its conservation. The aim of the work was to collect data on population dynamics of the species and identify habitat and climatic factors affecting population growth. We studied dynamics in all existing 7 populations during the period from 2006 to 2020 were collected. We linked these data to information on population dynamics, habitat and climatic factors and analysed them using Integral projection models (IPM). The study presents the importance of individual habitat and climatic conditions on the dynamics...
Countryside 3.0
Přikrylová, Monika ; Kekel, Roman (referee) ; Kristek, Jan (advisor)
The proposal follows up on the undergraduate semester work which dealt with a topic of data centers - a lifestyle based on data circulation. Growing needs of city dwellers, coupled with the demand of constant connectivity, are reflected in the transformation of the landscape which is being occupied by gigantic data centers. Those data centres in the loopback reconfigure the environment of cities that use their instant and "unlimited" computing power. The landscape is becoming the engine room of digital urban life. The thesis develops social and environmental issues of "continuity between a city and a country” and outlines a problem of self-sufficiency and awareness of the energy intensity of current urban lifestyle. In my work I focus on one of the by-products of data centers. That is waste heat, which has a negative effect on the quality and lifespan of electronic components - it is undesirable. Data center entrepreneurs have found a way to divert unfavourable attention from the debate about the energy demand of big data. They transform waste into a desired commodity by replacing conventional forms of heating with a system newly based on the supply of waste heat. Therefore, they are becoming significant suppliers of thermal energy. The phenomenon of heat recycling neutralizes external criticism of big data by making urban life literally dependent on it. The sustainable future of data center operations takes place largely without critical debate. On the contrary, it confirms data production as a process that literally drives everyday life. This new wave of green techno-optimism and related implementations is shrouded in a discourse of innovation, environmental friendliness and smart data processing. The diploma thesis deals with the phenomenon of commodification of waste heat of a specific data center, and its potential for symbolic and material transformation of the urban environment. The critical dimension of this transformation allows visitors to literally experience first-hand the manipulation of the climate of a specific location - the new city market in Brno. Other issues arise in connection with the recycling of waste heat. What will happen when big data streams become a raw material to replace older forms of energy supply in an urbanized world? What will be the impact on the city´s heating, the economic and symbolic importance of data center entrepreneurs?

Bartík, Lukáš ; Huszár, Peter (advisor) ; Bednář, Jan (referee)
The subject of this diploma thesis is study of the impacts of different implementations of turbulence and convection in the Regional Climate Model (RegCM, version 4.6) on the ability to predict the chemical pollution of the troposphere in Europe, which was simulated by the chemical transport model CAMx (Comprehensive Air quality Model with extensions, version 6.50) driven by RegCM meteorology using offline coupling of theese two models. Thesis also includes a brief description of the tropospheric chemistry, a discussion of the influence of meteorological conditions on changes in pollutant concentrations in the troposphere, a brief introduction to the regional climate modeling, a description of both models and method of their coupling. The main focus of the thesis is the analysis of the impacts of different parameterizations in RegCM model simulations on some climatic elements, validation of air temperature and precipitation, analysis of the impacts of changes in driving meteorology on ozone, nitrogen dioxide, sulfur dioxide and fine aerosol, validation of model concentrations of these pollutants with measurements at rural monitoring stations and comparison of column concentrations of nitrogen dioxide with satellite measurements.
