Occurrence and characteristics of ide (Leuciscus idus Linnaeus, 1758) catches in drainage area of the Morava River
Prokeš, Miroslav ; Baruš, Vlastimil ; Peňáz, Milan
The ide, Leuciscus idus belongs to autochthonous, less numerous and endangered (vulnerable) fish species of the Czech Republic. In 2004, the fishing on ide was conducted on 51 non-salmonid (NS) fishing-grounds of the Moravian Anglers Union (MAU) on water area of 4622.4 ha. In total, 432 ides (= 0.31 ind.ha-1; 0.25 % of all captured fish) and 332 kg of ide biomass (= 0.23 kg.ha-1, = 0.10 % of total mass of captured fish) were captured in 2004. Mean individual mass of ide was 0.78 kg. In the period 1990-2004, 0.11 ind.ha-1 (= 0.067 % of all captured fish) and 0.075 kg.ha-1 (= 0.035 % of total mass of captured fish) in the NS fish-grounds of MAU were captured yearly. During 1953-1978, 1.67 ind.ha-1 and 1.41 kg.ha-1 of the ide were captured yearly in the riverine fishing-ground Dyje 7. General trend of catches is decreasing. Legislative species protection, artificial reproduction and restocking of fish fry and 1+ juveniles were realized.

The Founders of Post-Keynesianism and the Concept of Reswitching
Kraffer, Robin ; Potužák, Pavel (advisor) ; Chytilová, Helena (referee)
The thesis deals with the evolution of thoughts of Joan Robinson's, Nicholas Kaldor's, Piero Sraffa's and Luigi Pasinetti's with regards to the issue of reswitching. Discussing Robinson, Kaldor, and Sraffa, it addresses the importance of the discussion on imperfect competition and Keynes's theory for developing their opinions within the capital theory. This issue was challenged in the 50s by Robinson who asked how capital can be measured. She discovered an option of reswitching to a more capital-using technique during a wage increase, but she did not focus on it very much. The thesis also seeks the importance of Sraffa's solution to the invariant standard of value for developing the debate on reswitching the technologies in the 60s, which was joined by both Pasinetti and Robinson. However, Robinson refused again in the 70s to deem the reswitching important within the critique of the neoclassical theory, and thus joined Kaldor who had voiced similar thoughts. At the end of the thesis, the question of Robinson underestimating the importance of reswitching, as pronounced by Pasinetti, is answered - she underestimated it in the 50s, whereas it is impossible to give a clear answer when it comes to the 70s, despite the differences found among Post-Keynesians and Neo-Ricardians.

Social and health aspects of smoking in the Army of the Czech Republic
ŠVÁB, Jindřich
Bachelor thesis deals with the theme of tobacco smoking among soldiers of the Army of the Czech Republic, ordepending on them. The aim of this thesis is to describe the situation of smoking in a selected group of respondents from two military batallions in southern Bohemia. The otheraimis to find out what Professional soldiersmean about negative lifestyle factors of smoking, and are they aware of the social and health aspects of smoking. This bachelor thesis is dividend into the oretical and research part. In the theoretical part are provided informatik about tobacco, health consequences of smoking, addiction, the impalt of smoking on smoking in ACR. The research part, which was performed by a questionnaire, deals with addiction on nicotin in ACR. It examines the quantity of smokers and non-smokers in the workplace, relations between soldiers and the influence of stressfuls ituations on smoking. The results show that the degree of dependence on tobacco products at the Czech Army is a few percent lower than in the general population (28-32% of the population), and 25% of smokers of hundred respondents between 20-35 years of age. Surprisingly it was also found that stressful situations that are caused by demanding service in the Army, do not call the selected respondents desire a cigarette or use other tobacco products. This group accounts for only 2% of a hundred respondents.

Korupce v křesťanském národě: „Ovlivňuje křesťanská víra úroveň korupce ve společnosti?“
Kraus, František ; Houdek, Petr (advisor) ; Svoboda, Miroslav (referee)
What are the determinants of corruption? This thesis builds upon contemporary approaches to assessing the level of corruption in different countries using purely economic determinants such as the aggregate income, level of education, openness to trade or taxation. This method is further enhanced by involving variables mapping the religiosity of the surveyed states as institutional determinants. Faith works as an agent that reduces selfish behavior and stresses moral values, thus it should prove to reduce corruption. The dataset involves data of 30 countries of the Organization for Economic Cooperation and Development (OECD) in the years 1999-2010. Two independent OLS models are set up using corruption perception indicators as endogenous variables; one with purely economic determinants, and the other with added religious determinants of corruption. Expansion of the model gives out a more robust set of results with greater determination. The results show that increasing number of Protestants in a society correlates with lower levels of corruption. The effect of the government spending on education has been considerably reduced after involving the religious variables. However, corruption does not seem to be influenced by the percentage of Christians in total population.

The Macroeconomic Impacts of the Selected Oil Shocks in the United States of America
Šikulová, Markéta ; Johnson, Zdenka (advisor) ; Tajovský, Ladislav (referee)
The aim of this study is to analyze macroeconomic impacts of four selected oil shocks on the United States economy and their subsequent comparison. The first part of this study deals with the theoretical background of supply shock, its influence on the economy, and the possible responses of economic policy. Furthermore, in the first part I focus on the historical events that led to the oil crisis, specifically on the OPEC oil embargo imposed on the United States, production cuts caused by the Iranian revolution, Iran-Iraq War and Persian Gulf War and on the demand as well as the supply factors that led to the oil shock of 2007-2008. The second part of this study presents the specific impacts of four selected oil shocks on the US economy and their comparison. Based on the findings, it was possible to confirm the hypothesis saying that past oil shocks, especially those that took place in the 1970's, had more negative impacts on the United States economy in comparison with those that happened more recently. In other words, that the effects of changes in oil prices have lessened over time. There are many reasons of this moderation, but the most important ones include more effective monetary policy response, the decrease in wage rigidities, and more recently also the decline of United States dependency on imported oil.

Steam boiler for demolition wood
Mazal, Lubomir ; Skála, Zdeněk (advisor)
The threat of depletion of fossil fuels is the driving force to diversify energy sources in the Czech Republic respectively in the European Union but also worldwide. One of these potential sources are being biomass boilers. The construction of these boilers has expanded in recent years because of government support for the construction of clean energy sources. Whether it is a burning of clean biomass or just incorporation of biomass to fossil fuels, teh substitution of fossil fuels and biomass boilers are the ideal solution. Their major advantages include significant reductions in emissions, mainly sulfur compounds, organic closure of the cycle of CO2 and disposal costs of spent residue.

Economy of Chile in 1960s and 1970s with Accent on Market Reforms after 1973
Strejčková, Klára ; Pekárek, Štěpán (advisor) ; Ševčík, Miroslav (referee)
This bachelor thesis puts the stress on the analysis of economic reforms approved in Chile in the 60's and 70's years of the 20th century. The focus of this work is profoundly dedicated to the analysis of two important macroeconomic indicators: developments of inflation and trade exports, bearing in mind the context of the coup in 1973 which is seen as a direct consequence of the communist rule of the Salvador Allende's Cabinet (1970-1973). The Allende's Cabinet strove to transform the Chilean economic society into a socialist one. The bachelor thesis has validated a hypothesis stating that the pro-market reforms approved after 1973 led to diversification of the Chilean export as well as a gradual and progressive stabilization of the country's inflation that had reached as 350 % during the socialist Allende's government. This work brings a comparison of two very different economic doctrines that formed Chile in the 70's of the last century. There is being compared a socialist government approach, having focused on nationalizing of the private sector, to the liberal government's approach aimed at decreasing the public sector, privatization as well as tearing down international trade barriers.

The Noise Spectroscopy of Radiation Detectors Based on the CdTe
Zajaček, Jiří ; Štourač, Ladislav (referee) ; Hájek, Karel (referee) ; Grmela, Lubomír (advisor)
The main object of this work is noise spectroscopy of CdTe radiation detectors (-rays and X–rays) and CdTe samples. The study of stochastic phenomenon and tracing redundant low-frequency noise in semiconductor materials require long-term measurements in time domain and evaluate suitable power spectral densities (PSD) with logarithmic divided frequency axes. We have used the means of time-frequency analysis derived from the discrete wavelet transform (DWT) and we have designed the effective algorithm for PSD estimation, which is comparable with an original analog method. CdTe single crystal with Au contacts we can imagine as a series connection of two Schottky diodes with a resistor between them. The bulk resistance at constant temperature and other constant parameters changes due to the carrier concentration changing only. The p-type CdTe sample shows metal behavior with every temperature changes. Semiconductor properties of the sample begin to dominate just after some period of time. This behavior is caused by the hole mobility changing. The voltage noise spectral density of 1/f noise depends on the quantity of free carriers in the sample. All the studied samples have very high value of low frequency noise, much higher than it should have been according to Hooge’s formula. The excess value of low frequency noise is caused by the low carrier concentration within the depleted region.
