Four weeks before the collapse of the Berlin Wall in 1989 an eleven-year-old flees the Soviet Union with her young father. As political refugee determined to eventually settle in the United States they hastily abandon the girl's estranged alcoholic mother, future stepmother, their friends and relatives, their collection of books and all but a handful of family photographs. She eventually attempts to seek out and recover the people, ideas and objects lost on that voyage to America by going back to a much changed Russia and stitching together the scattered and forgotten pieces in between her old and new homes through dream-like snapshots. Two decades after her emigration the author examines the concept of bad luck in one's travels, the significance of the number four, ambivalent attachments, learning to mother from a place of abandonment, the familial legacy of escape and the pursuit of wholeness within inconsolable loss. The un-tellability of the story is considered through the lens of Sappho, Bernadette Mayer, Yoko Ono, Roland Barthes, Doris Lessing, Nico and many other surrogate mothers and fathers brought together as a chorus in a multi-vocal, lyric approach.

Magister Economicae - MEcon / China has embarked on a wide range of economic reforms in the past thirty years. One of the major reforms was to restructure state-owned enterprises (SOEs) into public listed companies (PLCs) to improve the performance and quality of corporate governance of SOEs. However, the unique phenomenon of China’s equity market is that the state continues to hold a controlling stake in PLCs with less than 40% of shares tradable in the stock market. This seriously affects the performance and quality of corporate governance of China’s PLCs. This mini-thesis investigates the effects of split-share structure reform on SOEs in China, with particular focus on an analysis of the relationship between ownership structure and firm performance of listed companies. By using a sample of the top 50 companies based on the ranking of the 2004 Fortune top 100 PLCs, a negative correlation was found between the state ownership structure and firm performance of China PLCs before the announcement of split-share structure reform. However, by using the same samples and techniques, the analysis shows that the improvement in the diversified ownership structure had a positive impact on firm performance in China PLCs after the reform.

Objective: To determine the change in HRV in concussed varsity athletes from baseline to post-injury to return to play. Design: Quasi-experimental, repeated measures design. Participants: five male varsity athletes four rugby, one basketball (mean age 19.6 ± 1.52 years), number of previous concussion 1.6 ± 0.55. Measurements: HR & HRV frequency domain (LF n.u., HF n.u., LF/HF ratio, Total Power) & Heart rate (bpm) during both seated rest and steady state exercise using a stationary cycle. Results: Repeated measures ANOVA revealed a significant difference between baseline (pre- injury) resting heart rate and first post-injury assessment resting heart rate (p=0.037). Resting Total Power was significantly different between baseline (pre-injury) and first post-injury assessment (p=0.044) and between first post-injury and second post-injury assessment (p=0.010). No statistical significant differences in any variables were found during exercise, however the trends in the changes of HRV were similar to other research studies and could be of clinical importance. Conclusion: Athletes display dysfunction in neuroautonomic cardiovascular regulation post-concussion as seen with changes in HRV. Findings of this study warrant further investigation into the use of HRV as a marker of concussion and concussion recovery. / Graduate

John D. Caputo and Gianni Vattimo are two of the main thinkers in continental philosophy’s return to religion. This return is accommodated by the basic theoretical framework of irony, which is predominantly an unspoken determinant upon textual meaning. In this continental sense, irony affirms and negates the subject matter that it speaks about. Adopting this framework, Caputo and Vattimo suggest that a new Christian-irony is desirable to avert a collapse back into the violence that results from metaphysics, either modern or classical, by remaining in deconstruction’s loosely held wavering between theism and atheism. The question that remains to be proven, however, is whether their ironic method of writing is not inadvertently continuing the negative effect of the Nietzschean-Heideggerian paradigm by persisting with the literary style of writing that is intrinsic to it, even while openly refuting it by their affirmative Judeo-Christian surface content.

In this thesis, I examine the following three temporal influences on the cross-section of stock returns: disclosure and analyst regulations, the subprime credit crisis, and time-varying investor sentiment. The thesis consists of three essays. The first essay deals with the influence of regulation. Between 2000 and 2003 a series of disclosure and analyst regulations curbing abusive financial reporting and analyst behavior were enacted to strengthen the information environment of U.S. capital markets. I investigate whether these regulations benefited investors by increasing stock market efficiency. After the regulations, I find a significant reduction in short-term stock price continuation following analyst forecast revisions and past stock returns. The effect was more pronounced among higher information uncertainty firms, where I expect security valuation to be most sensitive to the regulations. Further analysis shows that analyst forecast accuracy improved in these firms, consistent with reduced mispricing being due to an improved corporate information environment following the regulations. My findings are robust to controlling for time trends, trading activity, the recent financial crisis, and changes in firms’ analyst coverage status and delistings. In the second essay, I examine whether the value premium survived the recent subprime credit crisis. I find that value stocks underperformed growth stocks during the crisis, resulting in a value discount, while the value premium was significantly positive before the crisis. This is consistent with value stocks being riskier than growth stocks because they are more vulnerable during bad times. The value premium reversal during the crisis worked primarily through financially constrained firms, suggesting that the effect was due to the adverse influence of the crisis rather than confounding effects. The results are robust to controlling for common risk factors and alternative financial constraint proxies. The third essay is related to time-varying investor sentiment. Recent literature in financial economics has examined whether investor sentiment affects asset pricing. An open question is whether an investor sentiment effect reflects mispricing or risk compensation. Currently, the literature supports the former view by documenting that investor sentiment predicts realized stock returns beyond the explanatory power of state-of-the-art factor models. But, despite its popularity, estimating expected returns from realized returns has limitations. I re-examine the evidence on investor sentiment using accounting-based implied costs of capital (ICCs). I find that ICCs cannot explain the sentiment effect on stock returns. If ICCs are reliable expected return proxies, this suggests that the investor sentiment effect does not exist ex ante and confirms previous evidence that mispricing is the driving force behind the investor sentiment effect on stock returns.

This diploma thesis called "Investment in real estates as a method how to secure a retirement" describes in its first part alternative possibilities of saving money for a retirement and briefly mentions pension replacement rates in the Czech Republic and other countries. In the next chapter there are definitions of basic real estate field terms, descriptions of taxes connected with transactions in the realty market and basic valuation method. In the practical part trend of housing development, level of housing and course of realty price are analysed. In the next chapter return on investment in region areas is calculated. The development of a mortgage market is outlined and thus a profitability of investment into flats followed by their rental in selected cities in the Czech Republic is calculated.

The main objective of this thesis is to provide the management of a company with a self- contained view on problems associated with the Contact Management as one component of the implementation of Customer Relationship Management (CRM). The thesis is primarily drawn from internet sources in order to obtain the most realistic and accurate view of given problems. The introductory part of this thesis focuses on an analysis of the areas that affect the success of the implementation of Contact Management. It highlights problems with the quality of data in companies, introduces the contributions of business architecture, and the concept of a single customer view within a company. The following part of the thesis focuses on problems involving the integration of data within a company and analyzes the problem areas concerned with the implementation of a uniform integration platform. The main part of the thesis focuses primarily on the return of investment from an application operating Contact Management and also from an active data warehouse as one of the possible solutions for the implementation of Contact Management. The thesis provides a detailed view of the classification of costs and benefits, which is necessary for relevant analysis. Together with a view on the return of investment, the thesis also analyses the design of systems for the management of the active data warehouse. The final part of the thesis focuses on problems with the implementation of householding as one part of Contact Management. This explains a possible way to implement householding within a company. The main contribution of this thesis is, firstly, to develop an overall view of the problems of Contact Management and, secondly, to provide the management of a company with information which is necessary for appropriate decisions about the solution that will radically affect the success of the entire company.

This thesis deals with the efficient usage of public resources. It defines the meaning of the efficiency and also describes methods by which efficiency can be evaluated. It also deals with a quality rating in culture and the issue of financing of culture, especially theaters. An important part of this thesis is also dedicated to the cultural policy of the Czech Republic and description of the grant system of the City of Prague. The last part of the thesis is a case study, from which the most important part is to analyze the efficiency of cultural grant -- as an example is taken The Semafor Theatre. The analysis is performed using an alternative approach to assessing effectiveness, within which are examined by effects arising from the expenditure of visitors of the theater and also the impacts on the theater and its suppliers. Evaluation of tax deductions leads to conclusion, what is the return of a grant to public budgets.

Grains on the surfaces of airless bodies are continually being modified due to their exposure to interplanetary space, a phenomenon known as space weathering. This dissertation uses a multi-faceted approach to understanding space weathering of the lunar and asteroidal surfaces. Chapters 1 and 2 provide an introduction to space weathering and a discussion of the methods employed in this work, respectively. Chapter 3 focuses on the analysis of returned samples from near-Earth asteroid Itokawa using the transmission electron microscope (TEM) and contributes to the first-ever comparison of microstructural and chemical features of space weathering in returned samples from two different airless bodies. This research uses high-resolution imaging and quantitative energy-dispersive x-ray spectroscopy (EDS) measurements to analyze space weathering characteristics in an Itokawa soil grain. These analyses confirm that space weathering is operating on the surface of Itokawa, and that many of the resulting features have similarities to those observed in lunar soils. Results show that while there is evidence that both major constituent space weathering processes are operating on the surface of Itokawa, solar wind irradiation, not micrometeorite impacts, appears to be the dominant contributor to changes in the microstructure and chemistry of surface material. Chapter 4 presents a detailed study of nanophase Fe (npFe) particles in lunar soil samples. For the first-time, the oxidation state of individual npFe particles was directly measured using electron energy-loss spectroscopy (EELS) in the TEM. The results show that npFe particles are oxidizing over their time on the lunar surface, and that the amount of oxidized Fe in the nanoparticles is correlated with soil maturity. The EELS data are also coupled to atomic-resolution imaging, which is used to determine the structure of the nanoparticles, confirming their mineral phase. This work challenges the long-standing paradigm that all npFe particles are composed of metallic Fe and that the chemical composition of these features remains static after their formation. A theoretical modeling investigation of the influence that npFe particles of different oxidation states have on the spectral properties of the material is also presented. The model results show that varied Fe-oxidation states of the nanoparticles can produce subtle changes in the optical properties of the soils, including the degree of reddening and the attenuation of characteristic absorption bands. These findings should be accounted for in future modeling of reflectance spectra. Chapter 5 presents a novel technique for simulating space weathering processes inside the TEM. Using an in situ heating holder, lunar soils were subjected to both slow- (~minutes) and rapid-heating (<seconds) events to simulate micrometeorite impacts. The slow-heating experiments show that npFe forms at ~575 ºC, providing a temperature constraint on initial npFe formation. Lunar soil grains that were subjected to a single, rapid, thermal pulse show the development of npFe particles and vesiculated textures near the grain rim. The vesicles were imaged and the npFe particles were imaged and then mapped with EDS. The oxidation state of the npFe particles was confirmed to be Fe^0 using EELS. Several lunar soil grains were subjected to multiple thermal shocks to simulate longer exposure times on the lunar surface. With each heating cycle, the number and size distribution of the npFe particles changed. The average size of npFe particles increased, and the size distribution became more gaussian after multiple heating events, versus the asymmetric distribution present after only one heating event. These results provide insight into the particle growth dynamics for space weathered soils and could offer a new way to place relative age constraints on grains in lunar soil.Chapter 6 provides a summary of the work presented here, discusses its implications for understanding space weathering processes across the solar system, and presents a perspective on the future of space weathering studies.
