Comparison of various methods monitoring insect diversity in sown flower strips and neighboring fields of winter wheat and winter oilseed rape
Kolařík, David ; Kazda, Jan (advisor) ; Josef, Josef (referee)
In this study we deal with comparison of insect monitoring methods on flowering strip, wheat and oilseed rape. The experiment is located at two study sites: Crop Research Institute at Ruzyně and Experiment unit of Czech University of Life Sciences in Uhříněves. The experiment was carried out in 2015.
To make monitoring we utilized sweeping net, Möricke yellow traps, transect counting and as a supplementary method we utilized light trap. Monitoring was done in 25 of June, 16 of July and 12 of August 2015. These dates were chosen because of flowering of the strip which was the most important issue in this study. As a result of this the insect diversity in other almost harvested variants was quite low.
The most important insect species quantities were collected from Möricke traps in all three variants. But this fact could be naturally based on the attractivity of the yellow color, so we can´t reliably say, if in out of bloom rape or wheat could be present this high amount of insect or if it is only being attracted by color of the trap from the neighborhood.
The second method with the highest insect occurrence was sweeping net. Again the highest species diversity was described from the flowering strip.
The lowest amount of insects was noted in transect counting. This method has (contrastingly to the others) disadvantage in the high possibility of fail to detect small insect, which are normally noticed by the other methods.
Light trap monitored about the highest species number, where the majority of species belong to order Lepidoptera. That sway this method was employed only to enrich the species diversity.

The economic development of Manchukuo in 1932-1945
Kolařík, David ; Skřivan, Aleš (advisor) ; Tajovský, Ladislav (referee)
The aim of master thesis is to analyze the economic development of Manchukuo and to answer the question whether the establishment of Manchukuo had positive or negative impact on the economic development of the area. The analysis of the economic development of the region in 1929-1945 proves that the economic impact on the development of the area was positive. Despite an effort to have Manchukuo economically self-sufficient, the region was still very dependent on Japan in both economical and political aspects. However, the comparison of Chinese and Manchukuo's economies shows a higher level of economic development of Manchukuo. The thesis uses the method of the probe and historical-critical method. The conclusions are primarily based on historical and up-to-date literature written by foreign and Czech authors.

The analysis of "Too Big to Fail" policy in the environment of financial institutions
Kolařík, David ; Lipka, David (advisor) ; Pichaničová, Ludmila (referee)
The aim of bachelor thesis was to answer the question whether politicians make their decisions about the "Too Big to Fail" policy on advice of economists or for other reasons. The bachelor thesis clarified many opinions and recommendations of economists, which were expressed in empirical and theoretical studies. Economists clearly thought that the government should not pursue the "Too Big to Fail" policy and thus not provide the assistance to financial institutions at risk of bankruptcy. Considering the fact that politicians provide the financial assistance to large financial institutions in most cases, the hypothesis that politicians act in case of "Too Big to Fail" according to recommendations of economists was rejected. Furthermore the bachelor thesis mentioned reasons that may influence decisions of politicians and alternative solution of financial institutions insolvency.
