Study of pesticide degradation using advanced oxidation processes
Vlach, Tomáš ; Repková, Martina (referee) ; Mravcová, Ludmila (advisor)
In the master’s thesis are expleined and described proceses and terms related by problematic degradation of pesticides using advenced oxidation proceses and their possibilities of determinations. The essence of the experimental work was development and validate created method for determination of chosen pesticides. Degradation of this pesticides by advenced oxidation proceses and their determination after degradation. The aim of the work was compare chosen oxidation methods and summary of results for designe of the most appropriate method.

Income Elasticity of Water Demand: A Meta-Analysis
Vlach, Tomáš ; Havránek, Tomáš (advisor) ; Červinka, Michal (referee)
If policymakers address water scarcity with the demand-oriented approach, the income elasticity of water demand is of pivotal importance. Its estimates, however, differ considerably. We collect 307 estimates of the income elasticity of water demand reported in 62 studies, codify 31 variables describing the estimation design, and employ Bayesian model averaging to address model uncertainty inherent to any meta-analysis. The studies were published between 1972 and 2015, which means that this meta-analysis covers a longer period of time than two previous meta-analyses on this topic combined. Our results suggest that income elasticity estimates for developed countries do not significantly differ from income elasticity estimates for developing countries and that different estimation techniques do not systematically produce different values of the income elasticity of water demand. We find evidence of publication selection bias in the literature on the income elasticity of water demand with the use of both graphical and regression analysis. We correct the estimates for publication selection bias and estimate the true effect beyond bias, which reaches approximately 0.2. 1

Irrational Behaviour
Vlach, Tomáš ; Koubek, Ivo (advisor) ; Kvaček, Jan (referee)
This thesis questions the notion of rationally behaving individuals as an as- sumption of microeconomic and macroeconomic models. Its goal is to show that foundations on which the modern economics is built are not so much solid. Selected topics are discussed theoretically and subsequently confirmed empir- ically by existing research studies. Afterwards, they are extended by related findings and potential implications for human behaviour. The thesis contains examples of irrational behaviour in which it is possible to behave rationally as well as examples in which it is very difficult to do so. The results imply that irrationality is present in many different domains. Because the assumption of rationality is repeatedly violated, economic models are not able to properly describe and predict human behaviour.

1968: Tlatelolco Massacre from the Perspective of Intelligence Servicec and Diplomatic Missions of the United States to Mexico
Vlach, Tomáš ; Opatrný, Josef (advisor) ; Buben, Radek (referee)
(in English): This diploma thesis deals with events related to student protests in 1968 in Mexico during which occurred a violent suppression of demonstrations against a rigid political system controlled by the PRI for several decades. This diploma thesis describes the course of the demonstrations from June to October 1968, using declassified diplomatic notes and intelligence prepared by relevant bureaus of the United States of America operating in Mexico as a source. The well-known and mapped events of student protests in Mexico in 1968 which escalated with the bloodshed in the square in Tlateloclo, Mexico, D.F., where soldiers and policemen interfered with protestors, are examined in the perspective of American diplomats and intelligence officers.

Legalization of Cannabis for Non-medical Purposes in the United States: Discrepancy between Federal and State Laws
Vlach, Tomáš ; Sehnálková, Jana (advisor) ; Calda, Miloš (referee)
This thesis focuses on the issue of cannabis legalization in Colorado. Legislation adopted at the federal level prohibits production, distribution and consumption of cannabis. Through public ballot initiatives, use of cannabis for non-medical purposes was legalized on the state level. This approach represents a fundamental change in drug policy and, in the future, it could affect federal drug policy regarding cannabis. This thesis uses the example of Colorado to illustrate the inconsistency in the legal approach to cannabis between some of the U.S. states and the federal government. By describing and analyzing the control measures in Colorado, this thesis aims to identify various regulatory risks, which might cause conflicts with the federal government. The thesis points to the liberal aspects of the regulation in Colorado and confronts the discrepancy with the directive of the federal government to establish a strong regulatory framework that is consistent with federal priorities in the area of law enforcement. The thesis contains a set of recommendations that contribute to reducing potential negative effects. Even though the federal government did not interfere with state's cannabis legalization, these recommendations could prevent a possible clash with the federal government, which still de jure...
