The aim of this thesis is a systematic study of physical properties of magnetic multilayered nanostructures. Namely it include multilayered spin valves NiFe/Cu/Co with magnetic anisotropy iduced by magnetic field applied during the deposition. Induced magnetic anisotropy influences exchange interactions between magnetic layers and so it gives the possibility to control magnetic properties of nanolayers. This is important for applications in MRAM, magnetoresistive read heads and spin-transfer-torque devices. Magnetooptic spectroscopy and Kerr effect hysteresis loop measurement were used as effective probe techniques. Secondly we examinated Ar3+ rf sputtering influence on multilayer interface quality level. We found out, that Ar3+ irradiation during deposition process has a possitive effect on interface quality.

The results of the laboratory study of reaction rate coefficients of several ion- molecule reactions with atomic and molecular hydrogen and molecular deuterium at low temperatures are presented in the thesis. The reaction rate coefficients of the N+ and H+ reaction with H2 were measured with respect to the nuclear spin configuration and rotational excitation of H2. The reactions of anions were a subject of the isotope exchange and isotope effect study. The measurements of the rate coefficients of H2O and D2O formation in the reaction of O- with H2 and D2, isotope exchange reactions OH- + D2 and OD- + H2, and associative detachment and charge transfer channels of D- + H interaction were performed. Experiments were carried out using an AB-22PT instrument with an ion trap. It has producing, guiding, trapping, and detecting systems for ions and a separate source of atomic H. The cooling system allowed to measure the temperature dependencies of the reaction rate coefficients at temperatures relevant to astrochemistry (10 K - 300 K)

DISSERTATION - Abstract in English Three Essays on Electricity Markets Author: PhDr. Petra Luňáčková Academic Year: 2017/2018 This thesis consists of three papers that share the main theme - energy. The articles introduce characteristics and behavior of electricity focusing on its unique properties. The dissertation aims at the Czech electricity market and analyzes also highly discussed solar power plants. The first article studies long term memory properties of electricity spot prices through the detrended fluctuation analysis, as electricity prices are dominated by cycles. We conclude that Czech electricity prices are strongly mean reverting yet non-stationary. The second part of the dissertation investigates possible asymmetry in the gas - oil prices adjustment. Oil prices determine the price of electricity during the times of peak demand, as the reaction of power plants fueled by oil is quick but marginal costs are high. We chose the gasoline - crude oil relationship known as "rockets and feathers" effect and offer two new tests to analyze such type of relationship as we believe that error correction model is not the most suitable tool. Analyzing international dataset we do not find statistically significant asymmetry. The third study assesses the impact of renewable energy sources, solar plants in...

(in English): A total of 62% of the Czech adult population currently suffer from overweight or obesity (BMI over 25). Overweight problems are mostly caused by bad eating and exercising habits. The web application Self-Coaching with cognitive behavioral therapy elements helps overweight or obese users to gradually change their bad habits. The objective of the research part of the thesis is to evaluate the effect of a 5-week use of the web application Self-Coaching and to find out whether or not this effect changes if the users are provided with a virtual intervention of an instructor trained in a cognitive behavioral approach to obesity treatment. I evaluated the percentage of weight loss as compared to the initial body weight, the energy and nutritional balance of the diet, vegetable intake, physical activity, the number of days of using the application and the use of the psychological section of the application (psycho-coaching). Weight loss was the identified main effect of the web application Self-Coaching. After five weeks, the users lost on average 2.5% of their initial weight. The intervention of the instructor helped to increase the number of days, for which the users used Self-Coaching.

This dissertation thesis centres on the stability and instability of the Vietnamese communist regime, and how to understand this topic today. This problem was explored with the help of an imported political tool, which Vietnam adopted from the USSR, through China, in the late 1940s, and which experienced a revival in modern economically liberalised Vietnam: emulation movements. This thesis assumed that historic and current emulation movements were designed to control, but also to bring legitimacy or a 'legitimacy effect' (and the related stability), through their different functions. It asked how they succeeded in this task comparatively, in their historic and current incarnations. The framework of functions of emulation movements in Vietnam combined with the theoretical concepts of David Beetham, Max Weber and Robert Lamb served as basic theoretical tenets. The thesis concluded that emulation indeed helped create foundational regime legitimacy and offered possible links to a new communist doctrine. The thesis showed that a predominance of successful legitimization, combined with legitimacy effect and Ho Chi Minh's charisma, helped stabilize the DRV regime, especially until 1954. The analysis of present-day emulation movements, however, showed the weakness of the VCP as it struggles to fulfil the...

Mate preferences and choices might be influenced by several factors, including close relatives. According to the imprinting-like effect, people prefer and choose partners similar to those with whom they grew up during childhood. The main aim of our research was to test, whether individuals choose their long-term partners on the basis of similarity (in personality traits) with their parent and/or siblings of the opposite sex (father and/or brother). The final sample of the study consisted of 211 heterosexual women (mean age = 27.34, SD = 5.36) who grew up with their father until at least 12 years of age. Respondents completed a set of questionnaires aimed at personality of their partner, brother, and father (NEO-FFI), the relationship quality with their father/brother during childhood (s-EMBU/QRI), and relationship satisfaction (RAS). Correlation and regression analyses have shown that heterosexual women choose partners similar to their fathers and brothers, especially in neuroticism. However, when compared correlation coefficients, it was found that fathers play a more important role. The retrospectively assessed quality of the relationship between the respondent and her father/brother during childhood did not have any effect on this similarity. Moreover, similarity between father/brother and...

The aim of this Master's thesis is to examine the securitization discourse used to construct the security threat coming from the veteran effect of the Islamic State's foreign fighters in Europe, and to see what kind of policies were adopted to counter it so far. The phenomenon of departing European citizens, who are becoming foreign fighters in the Syrian conflict, joining the ranks of the Islamic State, and then return back to their country of origin after having acquired combat experience or other training, has become a hot topic of discussion not only for academics, but also for politicians and ordinary citizens. To precise, this thesis is working with three main case studies, whose securitization discourse and security policies are analysed. These are: European Union, United Kingdom and France. The author was interested in finding out what similarities and differences can be found between the analysed countries, plus, whether there is some pattern of influence between the European Union and its member states in this area. The author of this thesis chose to use a comparative case study as a research design. It is useful to realize a contrast of contexts and therefore to discover specifics of the analysed cases. Two tables were created in order to clarify the operationalization of the analysed...

Existing evidence shows people are able to attribute an individual's behavioural characteristics based on their facial features with a certain level of accuracy; one such characteristic is the perception of physical strength in potential opponents within the male intersexual competition. Physical strength seems be assessed upon the level of masculine facial features development. However, attributions may be influenced by other factors - namely personality traits of the evaluator or the so-called Other-race effect. In this study portrait photographs of men from Europe and Africa were rated by a group of European evaluators on a perceived physical strength. The aim of this study was to assess the link between attributed physical strength, actual physical strength (grip strength) and facial morphology described by relative facial width (fWHR) the Index of Masculinity (potential effects of age, body weight and height on said variables were controlled for). The use of stimuli of different ethnic origin enabled us to test the accuracy of physical strength attributions and actual physical strength in context to the Other-race effect hypothesis. According to its wording people tend to attribute characteristics with higher accuracy to individuals, who belong to the same population, or with whom they are...

Pre-school education improves cognitive and non-cognitive skills of children, and the positive effects persist to adulthood. The literature provides rich ev- idence of beneficial effects of pre-school, some of them even causal. However, most studies come from the US, and the research lacks a comprehensive pic- ture of European countries concerning pre-school education. I contribute to the research by providing a comparison of European countries regarding pre- school attendance, pre-school skills, and test scores in fourth grade. In Section ??, I focus on the Czech Republic. The results show that more educated moth- ers are more likely to send children to pre-school. In most countries, children with stronger pre-school skills achieve higher results on standardized tests in fourth grade, which supports the idea of the existence of the Matthew effect. In the Czech Republic, pre-school attendance may increase fourth-grade test scores by 0.3 SD. The most important pre-school skill is the ability to read, which is associated with an increase in fourth-grade math achievement of 0.2 SD. The results contribute to the literature on pre-school education in Eu- rope; however, they should not be interpreted causally, as they are essentially a description of the pre-school context in Europe. 1
