The master’s thesis deals with the initiative of the Organisation for Economic Co-operation and Development, namely the Action plan on Base Erosion and Profit Shifting (BEPS). The aim of this thesis is to quantify impacts of selected BEPS measures on the tax bases of Czech companies. The paper is divided into a literary summary and a practical part. In the literary summary, important concepts of international taxation are defined and the BEPS action plan and the Anti Tax Avoidance Directive (ATAD) are presented here. In the practical part, selected BEPS measures are applied to model examples, and the impact on the tax base of Czech companies in the situation before and after the implementation of specific measures is quantified. The model examples result in an increase in the tax base and the tax liability of Czech companies in the situation after the implementation of the selected BEPS measures. BEPS measures applied to Czech companies in this thesis pose a negative impact on their tax planning.

and keywords in English The diploma thesis deals with the relationship between pupils' overall life satisfaction and school climate. In this work school climate is represented by four aspects: pupils' sense of security, social relations at school, school success and career planning. Another question which has been analysed is whether the pupils' life satisfaction is affected by the type of school. The relationships were verified on the data from the PISA survey from 2018 using hierarchical linear models. A significant association between the type of school and the pupils' overall life satisfaction has been present only when there were no other variables in the model that would describe the school climate. Another important phenomenon is a relationship between pupils' overall life satisfaction and relationships at school (not only with classmates, but also with teachers). Model 2 shows that good relationships with classmates and teachers could also be a weak moderator of the relationship between the negative experience of bullying and pupils' life satisfaction. In the analysis a positive association between academic achievements and life satisfaction was identified only when the academic achievements were represented by marks, not by the average reading literacy score. In this work the conclusions...

To rigorously study hot stars, we need to determine their properties as accurately as possible. This thesis focuses on improving the accuracy of parameters of two hot stars and contributes to the collection of stars with more known parameters. While photometric and spectroscopic data sets on hot stars δ Ori A and ω CMa are plentiful, the former is a triple star that suffers from having a faint spectrum of the secondary, which complicates its analysis, and the latter is a Be star, the origin, formation, and long-term variability of whose gaseous envelopes (veils) remain unexplained. Using mathematical techniques (Fourier transforms) and modelling software PHOEBE 1, properties of δ Ori A are determined, and conjecture on the presence of a circumstellar envelope in δ Ori A might be true by considering the shape changes of the Hα line. A conjecture that period changes of ω CMa correlate to the mass of the circumstellar envelopes seems to be proved true by considering variations of radial velocities, V/R ratio, and determining profile line asymmetry. 1

In real world environments, animals need to organize their behavior relative to other moving animals or objects; when hunting a predator, when migrating in groups or during various social interactions. In all of these situations, the animal needs to orient relative to another moving animal/object. To understand the role of the hippocampus in this ability we adopted a two-step approach. We developed a task that would mimic important elements of this behavior in the laboratory. The task required the rats to assess not only their distance from the moving object but also their position relative to the object. We further studied how neurons in the hippocampal CA1 subfield encode the subject, the moving object and the environment in the behavioral paradigm and how do these representations interact among themselves. In rats, we aimed to characterize spatial behaviors relative to moving objects and to explore the cognitive mechanisms controlling these behaviors. Three groups of animals were trained to avoid a mild foot-shock delivered in one of three positions: either in front, on the left side, or the right side of a moving robot. Using different variations of the task, we also probed whether avoidance was simply due to increased noise level or size of the retinal image or appearance of the robot. As the...

<div>Rain drop size distributions (DSDs) in severe convective storms are highly variable in time and space. DSDs can be derived from polarimetric radar observations at high spatiotemporal resolution but these observations are often lacking near the surface owing to radar horizon issues. Disdrometers provide “ground-truth” measurements and validation of radar-derived DSDs but are by nature limited point measurements. Moreover, substantial evolution of the DSD can occur between the lowest radar elevation angle and the surface. Recent studies have shown that hydrometeor size sorting (HSS) is an important and even dominant process contributing to DSD evolution in severe storms; many physical processes such as the strength of the updraft, transient effects, and storm-relative mean winds are contributing factors to continued size sorting. In this study, we focus on strong storm-relative mean winds that induce sustained size sorting owing to the different residence times of hydrometeors of different sizes as they fall in severe storms. The resulting differential advection leads to a distinct horizontal spread of hydrometeors of different sizes at the bottom of a given layer. The goal of this study is to evaluate the impact of size sorting on DSD evolution from the radar level to the surface. To accomplish this, we develop and apply a raindrop trajectory model to compute the evolution of DSDs between radar observations aloft and the surface. For simplicity and to isolate the effects of size sorting, we neglect processes such as breakup, collection, and evaporation, and assume a horizontally homogeneous wind profile. We use disdrometer and radar data, which measure DSDs at the surface and provide the observed quantities aloft, respectively. The disdrometer data was collected from portable disdrometers as a collaboration between Purdue University, University of Oklahoma, University of Massachusetts, and the National Severe Storms Laboratory during the VORTEX-SE 2017 field campaign. NEXRAD data from KHTX Huntsville, AL and KGWX Columbus Air Force Base, MS was retrieved from the National Centers for Environmental Information (NCEI).</div><div><br></div><div>We evaluate three separate cases, a tornadic QLCS on 30 April 2017, a cluster storm on 27 March 2017, and a squall line on 25 March 2017. After the radar data is pre-processed, we retrieve the DSDs from the radar by assuming a gamma distribution and discretize them into PARSIVEL bins to produce a gridded dataset of DSDs. We then apply the raindrop trajectory model to compute the DSDs at the surface which are then compared directly with disdrometer observations. Analysis and comparisons from all cases yield similar results in that-the sorted radar DSDs at the surface are overall closer to the disdrometer observations than the original radar DSDs aloft. Results also show that the spatial variation of DSDs is higher at the surface due to size sorting by the storm-relative mean winds.</div><div><br></div>

Construction industry is based on the evaluation of building environmental impact. The current situation shows buildings reaching high standards in the field of environmental sustainability, but they often neglect occupants' satisfaction. The International Well Building Institute (IWBI) has released a new building standard called WELL, whose aim is to create sustainable buildings paying attention to occupants' health and well-being. The goal of this thesis is to understand what does WELL add to existent building certification systems. There is a large number of certification systems, green codes, green standards and several other kinds of documents that influence the way in which designers think and develop their projects. A research background is carried out to identify their requirements and fields of applicability. The innovative concepts proposed by the IWBI, need to interface with requirements from different regulations or certifications. The gap analysis performed in this work highlights which are the gaps and the overlaps between WELL and Swedish building regulations (BBR), Miljöbyggnad, BREEAM-SE and LEED-IT. The White Arkitekter's office in Stockholm, known as Katsan and certified with Miljöbyggnad Gold, is used as a case study to have a more specific approach to the problem than the general approach provided with the gap analysis. The report shows significant gaps between WELL and the other regulations and certifications, which are reduced when considering the case study. The outcomes for the different standards have been compared and they have evidenced some innovative features present only in WELL. These features answer to the research question and underline what WELL adds to sustainability concepts.

My dissertation primarily focuses on the fabrication of materials for solid phase microextraction (SPME) and separation devices. In my first project, I used direct current magnetron sputtering (DCMS) to prepare sputtered silicon coatings on fused silica fibers. These fibers were then subjected to the chemical vapor deposition of 6-phenyhexylsilane (6-PH) as a stationary phase. Six different types of fibers were made using two different throw distances (4 cm and 20 cm) and three different silicon thicknesses (0.5, 1.8, and 2.8 µm). These coatings were characterized by time-of-flight secondary ion mass spectrometry (ToF-SIMS), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), spectroscopic ellipsometry (SE), and contact angle goniometry. These SPME fibers were evaluated using gas chromatography (GC). The extraction efficiencies of sputtered, 6-PH-coated fibers were compared to that of a commercial fiber (7 µm PDMS) for polycyclic aromatic hydrocarbons (PAHs). Our 2.8 µm thick sputtered silicon coatings showed competitive extraction of low molecular weight PAHs and ca. 3 times the extraction efficiency for higher molecular weight PAHs. In addition, it outperformed the commercial fiber by showing better linearity, repeatability, and detection limits. A method for analyzing polyaromatic hydrocarbons in baby formula was developed, which showed very good linearity (0.5-125 ppb), repeatability (2-26%), detection limits (0.12-0.81 ppb), and recoveries (103-135%). In my second project, I focused on preparing sputtered carbon SPME fibers using DCMS sputtering. These fibers were tested with and without PDMS coatings on top by SPME-GC-MS. In addition, a new SPME evaluation mix was developed for testing the newly developed SPME fibers. The evaluation mix included analytes with diverse functionalities and properties. Our best carbon fiber showed very competitive extraction capabilities on a per volume basis when compared with a commercial 95 µm carbon-based fiber. In a third project, I built an ALD system to deposit thin films inside GC capillary columns. This system has a unique design that also allows for ALD on witness silicon samples before and after the capillary column. This system yields very promising results with ALD of alumina inside 5 and 12 m long capillary columns. The ALD coatings deposited inside the columns were characterized by transmission electron microscopy (TEM) and energy dispersive X-ray analysis (EDX). The thicknesses of the coatings on witness shards were almost identical to the thicknesses of the coatings in the capillaries. My fourth project focused on characterizing a liquid polymer (diphenyl siloxane dimethyl siloxane (DPS-DMS)) via SE. This material was a potential stationary phase for our SPME fibers. Transmission measurements were obtained via a dual cuvette approach that eliminated the effects of the cuvettes and their interfaces. The optical function of this material was modeled with a Sellmeier function in its transparent region.
