Motivation and expectations of Czech students for university studies in Great Britain
Jeřábková, Tereza ; Balon, Jan (advisor) ; Uherek, Zdeněk (referee)
This study aims to identify and analyse the motivations and expectations of students who have decided to complete their full university studies in the UK. The thesis further examines the retrospective view of these students on their study abroad and their subjective perception of this experience. As part of the research, specific experiences that students had during their studies abroad and which had an impact on their personal development and life paths are investigated. Part of the study is also the identification of potential challenges and difficulties that students encountered in a foreign country and how these influences affected their motivation and determination to achieve their study goals. Last but not least, the work focuses on the assessment of student development at the personal and career level, thereby bringing insights into the benefits of this study format for the individual growth and professional perspectives of students.

Supernova driven super star cluster wind
Jeřábková, Tereza ; Wünsch, Richard (advisor) ; Walch-Gassner, Stefanie (referee)
In this thesis we study the interaction of supernova ejecta in the environment of young massive clusters. It has been already shown that winds of massive stars can be thermalized by mutual interactions inside the cluster and drive the strong star cluster wind. The SNe are, as discrete and extremely energetic events, in all ways diferent from the continuous stellar winds. This triggers the question under which parameter and if at all can the SNe ejecta interaction from a smooth star cluster wind. Therefore we at first parametrize the SNe explossions and based on the 3D simulations in FLASH we show for the first time that the convergence of the SNe ejecta interaction to a smooth star cluster wind is controlled by a single parameter ΠSN . The paramater ΠSN estimates the mean number of interacting SN ejecta based on a comparison of supernova rate and crossing time of SN ejecta in a cluster. For high enough values ΠSN > 1 the cluster is able to build up smooth a star cluster wind. This allows us to use a 1D semi-analytic code WINDCALC to calculate the cooling of the hot gas due to dust and estimate under which conditions the SNe-inserted matter is captured. This may explain the origin of so-called anomalous globular clusters. 1

Spectral analysis of the B[e] star V743 Mon
Jeřábková, Tereza ; Korčáková, Daniela (advisor) ; Krtička, Jiří (referee)
This thesis deals with the study of the star V743 Mon. Stellar spectrum contains forbidden emission lines of [O I], strong Balmer emission lines and also infrared excess. Due to this, V743 Mon belongs to the group of B[e] objects. Observed spectra indicate very extended and rotating circumstellar envelope composed of gas and dust. We study time variability using data obtained during 2004-2012 at the Astronomical Institue of the Academy of Sciences of the Czech Republic in Ondřejov. We reduce and rectificate these spectra. We mesure relative intensities, equivalent widths and radial velocities for lines Hα, [O I] and Fe II. Graphical description contains also lines Si II and He I. The observed spectra show time variability on both, long- and short-term scales. Spectra from SAAO observatory are used to study the short time-scale changes. The discussion of problems connected with different instruments is also presented. 1

Intergenerational construction of perception of poverty within families
Jeřábková, Tereza ; Spalová, Barbora (advisor) ; Kolomoiets, Maksym (referee)
This bachelor thesis deals with the study of the concept of poverty and its perception across two generations. This is among those who grew up in the socialism and their descendants who grew up after the transformation. The work aims to describe the intergenerational constructions of perceptions of poverty within families, to further analyze whether the concept of poverty differs between two different generations and, if so, on what these differences is based. Qualitative research is focused on middle-class Prague families, where using semi- structured interviews and the method of projective techniques I find out the attitude of respondents in the perception of the concept of poverty and their narratives associated with it. I use the research work of sociologists and anthropologists A. Schütz, M. Buchowski, M. Kreidl and R. Inglehart as theoretical starting points for qualitative interviews. The theory and data are then analyzed by a combination of narrative and thematic analysis. The main finding of this work is the importance of personal experience with poverty, which influences the further formation of the discourse on poverty.

Corporate culture of Simpleway s.r.o.
Jeřábková, Tereza ; Müllerová, Františka (advisor) ; Maléř, Jakub (referee)
My bachelor thesis is focused on the corporate culture. It deals with this issue from the theoretical point of view and the practical as well. Theoretical part is focused on the culture in general and then on the corporate culture. I describe the essence of corporate culture, its determinants and types of corporate culture. The practical part is focused on the corporate culture of Simpleway s.r.o. The main aim of this thesis, based on a questionnaire research, is to determine the strength and the influence of the corporate culture of Simpleway s.r.o. on its employees and if this company is suitable representative of strong company culture.
