The Impact of External Events on the Market Capitalization of Companies
Zelenka, Jaroslav ; Krabec, Tomáš (advisor) ; Veselá, Jitka (referee)
This diploma thesis analyses the relationship between external events (i.e. events with impact within the Czech Republic which cannot be influenced by local firms) and the value of market capitalization of companies on Prague Stock Exchange. The analysis of the 1994 to 2012 time series showed that even the most important political, economical and other events specific for the Czech Republic only have marginal impacts on values of companies on the Czech stock market. The impacts of corporate events proved to have much stronger such effects. The most advisable investment recommendation thus seems to be to ignore external events when deciding in which stocks to invest.

Effects of Insider Trading Regulation
Zelenka, Jaroslav ; Bolcha, Peter (advisor) ; Mičúch, Marek (referee)
This thesis analyses the relationship between insider trading regulation (broadly interpreted) and equity costs of firms on data from the Chinese, South African and Russian capital markets covering the years from 1995 to 2011. Time series analysis showed -- as expected -- that stock markets in each of the countries react in specific ways: E.g. none of the regulatory measures proved effective in decreasing the equity costs in the case of South Africa. Analysis of the Chinses and Russian data showed, however, a possible common feature of the participants on the two markets. It seems that these markets react to mere signals of upcoming regulatory measures rather than on these measures themselves. This interpretation of the results is thus in line with the rational expectations hypothesis.

Kompozity PMMA s anorganickým plnivem: interpretace vlivu struktury matrice za přítomnosti plniva
Dušková, Miroslava ; Dušek, Karel ; Zelenka, J.
The study showed that the properties of a glassy composite with crosslinked matrix adhering to the rigid filler particles are sensitive to the polymer network structure of the matrix . It was proved by morphological, swelling and mechanical studies that the adhesion between the crosslinked poly(methyl methacrylate) matrix and the ATH filler is maintained in the swollen state and during small-strain. In the swollen state or at temperatures about 60 °C above Tg, the mechanical relaxations are relatively fast and equilibrium can be reached within approximately one hour. A model of equilibrium swelling constrained by surfaces of various geometries has been developed based on statistical thermodynamics of (Gaussian) networks.

Constitutional Analysis of the Lisbon Treaty
Zelenka, Jaroslav ; Hudík, Marek (advisor) ; Skopeček, Jan (referee)
This work applies the constitutional analysis method on the evaluation of the EU constitutional setting's change after the possible approval of the Lisbon Treaty. We will focus on the part of the Treaty that has an impact on the character of the legislation connected with commodity taxation. Specifically, we will analyze the change of the voting rules of the Council and the change of the constitutional cognizance of the Council. After we draw the parallel between the Council and the revenue-maximizing Leviathan, we will be able to advocate for the conclusion of our analysis which is that the base and rates of the commodity taxation will change to the disadvantage of the taxpayer after the approval of the Treaty.
