Short-Term Determinants of the Idiosyncratic Sovereign Risk Premium: A Regime-Dependent Analysis for European Credit Default Swaps
Calice, Giovanni ; Miao, RongHui ; Štěrba, Filip ; Vašíček, Bořek
This study investigates the dynamic behavior of the sovereign CDS term premium for a group of European countries. The CDS term premium can be regarded as a forward- looking measure of idiosyncratic sovereign default risk as perceived by financial markets in real time. Using a Markov-switching unobserved component model, we decompose the daily CDS term premium into two unobserved components of statistically different nature (stationary and nonstationary) and study the determinants of their short-term dynamics. Specifically, we link these components in a vector autoregression to various daily observed financial market variables. We find that decomposition into the two components is vital for understanding the short-term dynamics of the entire CDS term premium. The strongest impacts can be attributed to CDS market liquidity, local stock returns, and overall risk aversion. By contrast, the impact of shocks from the sovereign bond market is rather muted. Therefore, the CDS market microstructure effect and investor sentiment play the main roles in sovereign risk evaluation in real time. Moreover, our results suggest that the response of the CDS term premium to shocks to financial variables is regime-dependent and can be ten times stronger during periods of high volatility.

Geneticky modifikované potraviny a jejich potenciál, rizika a etika
Ševčíková, Miroslava
Diploma thesis is focused on the genetically modified crops and their ethical aspects. At the beginning there were summarized existing findings about transgenic crops, biotechnologies and mechanisms of modification. Next step was the evaluation of legislation, which is valid not only for the Czech Republic but also for European Union. By the comparative method there were assessed positive and negative sides of a genetically modified food, which were followed by the questionnaire survey to find out a general awareness about GMO. The hypothesis was formulated that a genetically modified food is a solution of current food crisis. The hypothesis was confirmed, but with serious reservations. Results showed that GMO are perceived rather negatively and sceptically despite its indisputable advantages and a potential perceived in the Czech Republic and EU. This view is caused by not sufficiently conclusive scientific results concerning negative effect of this food on the human health.

Freezing technology of bull sperm in relation to its survivability and fertilization ability
Doležalová, Martina ; Stádník, Luděk (advisor) ; Jiří, Jiří (referee)
The aim of optimalization the insemination doses production is to provide the highest fertilization ability of spermatozoa during the demanding proces of processing fresh semen and its subsequent cryopreservation. Temperature changes causes spermatozoa damage during the cooling and freezing. Spermatozoa is exposed to cold shock and many others limiting factors, which leads to cell death and therefore to decline of fertilization ability of thawed insemination doses. For increasing spermatozoa resistance, exactly the plasma membrane resistance against cold shock was fraction of egg yolk LDL cholesterol (low density lipoprotein) at various concentrations into the comercially produced diluents added. It is believed that LDL acts possitively to plasma membrane and helps to maintain the fertilization ability of spermatozoa after thawing. Following step in the proces of insemination doses production is slow cooling of diluted semen and equilibration, when the straws are store at cooling box for 30 minutes to 240 hours. This period is necessary to penetrate of certain diluent components into the spermatazoa also maintain the balance between their intracellular and extracellular concentration. Also important is subsequent freezing temperature gradient of insemination doses. The most suitable freezing method is based on computer controlled temperature decline in freezing chamber which allows the precise control of ice crystals formation that could tear and kill the cell.
During 2012 to 2016 was repeatedly collected semen from the group of breeding bulls (n = 27, Holstein and Czech Fleckvieh breed) at AI centre. Semen which fulfill the standard entrance conditions in first step was evenly into several parts divided. For dilution the three types of comercially diluents AndroMed, Bioxcell and Triladyl with and without LDL addition were used. Into the diluents AndroMed and Bioxcell the concentration of LDL 4 %, 6 % and 8% into the dilent Triladyl 6 %, 8 % and 10 % was added. Diluted semen was filled into the glass capillares with volume 0,1 ml and temperature +4 °C. Subsequently the sample was placed to cold bath (0°C) for 10 minutes. Then the volume of capillare with physiological solution (37 °C) was mixed and for next 120 minutes was incubate. The effect of cold shock to proportion of live spermatozoa was evaluated by using Eosin and Nigrosine staining technique during heat test of spermatozoa survivability after spermatozoa heating and after 120 minutes of incubation.
The more suitable semen diluents which provide the higher spermatozoa resistance against cold shock were AndroMed and Bioxcell. Together the possitive effect of LDL addition into the diluents to lower decrease of proportion of live spermatozoa during heat test was found (P<0.05). The most suitable LDL concentration which had a favorable influence at spermatozoa resistance against cold shock was 6 % in diluent Bioxcell. Values of the proportion of live sperm were higher at the beginning of the heat test (+1.31% to + 3.2%) and after 120 minute incubation (+5.82% to +8.41%) compared to other diluents with and without addition of LDL.
In the next step the process of equilibration was optimized, is an important part of insemination doses production. The effect of the length of equilibration for subsequent fertilization ability of spermatozoa was evaluated using spermatozoa motility based of CASA and proportion of live spermatozoa after thawing and during heat survival test lasting 120 minutes (37 ° C). Suitable semen was diluted by comercially used diluent AndroMed based on soya lecithin, filled into the straws (0.25 ml), cooled and equilibrated in cooling box for 30, 120 and 240 minutes and freezed in programmable freezing box applying four types of freezing curves differing in temperature rate decline. There was used standard and by producer recommended 3. phase freezing curve, then 2. phase freezing curve, and 3. phase freezing curve with slower as well as rapid decline of temperature rate in freezing chamber, compared with standard freezing curve. The highest spermatozoa motility was found using 240 minutes of equilibration by +2.72% and +4.58% compared to other lengths of equilibration (P <0.05 to 0.01). The highest proportion of live spermatozoa was found using 120 minutes of equilibration (+6.87 % and +8.68 %). The highest average spermatozoa motility during heat test after thawing was achieved by using 2. phase freezing curve (from +2.97% to +10.37%, P <0.05), also in the proportion of live spermatozoa (from + 4.37% to +8.82%, P <0.01). When evaluating interaction between the length of equilibration and freezing curve (standard 3. phase and 2 . phase freezing curve), the highest average spermatozoa motility and proportion of live spermatozoa using 240 minutes of equilibration by both freezing curves was reached, there was no statistically significant differences. As well as, in all evaluated parts of this study the individual differences between ejaculate of bulls and within semen from one bull (P <0.05) as secondary effect were found.
To maintain good fertilization ability of semen during cryopreservation is necessary to increase the spermatozoa resistance against cold shock using addition of correct concentration of LDL into the commercially used diluents AndroMed and Bioxcell. Subsequently the fertilization ability of insemination dose is influenced by cooling, the length of equilibration and freezing. The length of equilibration 120 minutes and more as well as gentle way of freezing according to freezing curve, which ensures a gradual decrease of temperature in freezing chamber provided the higher average spermatozoa motility and proportion of live spermatozoa.

Analýza a hodnocení hospodaření rodinné farmy zaměřené na rostlinnou produkci
Martinová, Lucie
In this thesis, there was evaluated Mr. Bělín's farm, which is situated in the Olomouc region in a village called Čelčice. There is farmed less then 158 ha, about 90 ha is owned by the farm. The rent is from about 4 000 to 5 000 Kč/ha/year. The enterprise is focused only on crop production. There is grown winter wheat, spring barley, winter rape and sugar beet. The crops are grown on a high-quality blacksoil with a high production potential. Because of specialization to cereals and low number of crops in a sowing procedure, it's necessary to pay attention to a soil protection to avoid a soil degradation and to retain a long-term soil fertility. Data for the analysis of the crop production were used from the years 2011, 2012, 2013. The results evaluate the current situation of the farming. Optimization of growing techniques is performed in terms of sustainability of the system.
