Social isolation and loneliness of female university students during the COVID-19 pandemic
Gardianova, Tereza ; Richter, Eva (advisor) ; Skovajsa, Marek (referee)
of Diploma Thesis Abstract: The master thesis deals with the loneliness of university students (focused on women) during the pandemic of the COVID-19 disease. The work focuses on the identification of risk and protective factors of loneliness. It also examines coping strategies and compares their use between lonely and non-lonely students. The qualitative study identified risk factors associated with the pandemic (disruption of routine and everyday life, absence of university environment and reduction of social network and social contacts) and general risk/protective factors (social, personal, family environment, physical activity and nature). Coping strategies for university students are prevailed active, problem-oriented strategies. However, emotional strategies also appear during crisis situations. Passive coping strategies predominate among long-term lonely students. The main difference between lonely and non-lonely students was connected with the perception of loneliness. Non-Lonely students took loneliness as a means of self- development and personal growth. Based on the findings, a typology of loneliness was created.
Memory Functions in Children with Intellectual Disability
Hanzlíčková, Lucie ; Maulisová, Alice (advisor) ; Lukavský, Jiří (referee)
The diploma thesis called Memory functions in children with intellectual dissability is devoted to mapping cognitive functions, specifically with a focus on memory functions in children with diagnostically confirmed the mild mental retardation. The origin of the thesis is associated and based on the standardization of incipient Neuropsychological Battery for Children (NB-C) and with the necessity to validate the method in different clinical groups. The aim was to assess how children with cognitive deficits, especially with the mild mental retardation, react and score in the memory's subtests. The main goal of this thesis is to assess the level of memory functions of these children. Furthermore, attention is focused on the comparison of key memory's domains based on the administration of the Neuropsychological Battery for Children and the inteligence test WISC- III in comparison with a comparative group of children without cognitive deficits. The theoretical and literary review section is focused on three key areas. The first of them presents the topic of memory, its distribution within the framework of the processes and systems, currently diagnostic methods, and also the development of memory functions. The following chapter focuses on disorders of the intellect, the terminological background of...
Properties of color centers in diamond studied by methods of femtosecond laser spectroscopy
Streshkova, Neli ; Malý, Petr (advisor) ; Dzurňák, Branislav (referee)
In this work, we focus on the interaction of SiV color centers in diamond with femtose- cond light pulses. In the theoretical part, a script is developed to simulate the experimen- tal varying stripe length method and the effects of saturated optical gain are investigated. In the experimental part, photoluminescence and transient differential absorption under non-resonant excitation are studied. The result of the luminescence measurements are estimates of the effective cross-sections of single-photon absorption for the wavelengths 620 nm, 515 nm and 340 nm, as well as the effective cross-section of three-photon absorp- tion for 2000 nm. The result of the differential absorption measurements is the relaxation constant of the excited level of the SiV center and the upper estimate of the time duration of the initial dynamics. 1

Title: Comparison of the effectiveness of ice skate training using the change of directional speed exercices and powerskating in the U10 category Goals: The main goal of this study is to compare the effectivity of ice hockey skating training using partial skating tasks and training with the usage of change of directions speed. 8 skating tests were used to compare these two methods in the U10 category. Methods: The method of quantitative analysis was used to compare the results in each test. A total of 13 players under the age of 10 years with an average training age of 4.73 ± 1.15 participated in the research. A total of three test measrurements were conducted. The first one taking place before any stimulation for both groups. The second, which followed six weeks of intervention using skating technique and agility exercises respectively, and the third, which followed a further six weeks of intervention when the groups were rotated. The measured times were tabulated and then statistically processed. Results: After the second measurement (POST_1), the group starting with the skating technique improved in 7 out of 8 tests. The group starting with agility skating showed improvement in 6 out of 8 tests. The most significant improvement for both groups was seen in the 30m backwards test, with the group...
Risky communication between children and adults on the Internet: An observational analysis and recommendations for the development of algorithms predicting risky communication
Plášilová, Leona ; Androvičová, Renáta (advisor) ; Štětovská, Iva (referee)
Child sexual abuse is a burning social issue and has significant psychosocial impact on future life of the child. Domestic as well as global statistics show that this phenomenon has been partly shifting to the Internet, which often provides offenders with greater anonymity and wider reach. One of the preventive measures might be development of technologies using artificial intelligence and machine learning, which can automatically detect risky communication on the Internet, warn the victim and inform the offender about illegality of his behaviour. The presented work focuses on both analysis of offenders' behaviour and a fake victim (actress representing a twelve-year-old girl) in their joint online communication.The objective is to thoroughly investigate the course of such communication and analyse predictors (occurrence of specific types of messages), according to which it could be possible to detect offenders with higher risk of harm to the victim at the beginning of the communication. The analysis is based on communications with real offenders that were obtained in collaboration with creators of the documentary "V síti" (n = 34). They were selected based on the following criteria: communication on Facebook, at least 100 messages in the communication, it is assumed that the offender is an adult...
Examining Innovation-Growth View and Innovation-Fragility View: A Case of European Countries
Xu, Yunqiao ; Janda, Karel (advisor) ; Radošević, Slavo (referee) ; Hanzlík, Petr (referee)
This thesis examines the innovation-growth view and innovation-fragility view on the impacts of financial innovation on banking performances in 22 European countries. It focuses on three aspects of analysis: the relationship between financial innovation and bank growth, the relationship between financial innovation and bank stability, and the relationship between financial innovation and banking performance reduction during the COVID-19 pandemic. The panel data sample consists of 4479 active banks in 22 European Union countries from 2008 to 2020. This paper uses the fixed effects model. The paper finds that financial innovation contributes to both bank asset growth rate and bank loan growth rate. Banks with lower market shares, higher loan to asset ratios, and higher tier 1 capital ratios have faster asset growth rates compared to others. Financial R&D intensity value added leads to both lower bank z-score and lower log bank z-score, while the ratio of off-balance sheet items to total assets leads to a higher log bank z-score. There is also evidence for cross-country variation. During the COVID-19 pandemic, off-balance sheet items divided by total assets negatively impacts the change in ROA for banks between 2018 and 2020, which supports the innovation-fragility view.
Covalently linked molecular networks on metal-passivated surfaces
Slezák, Peter ; Kocán, Pavel (advisor) ; Matvija, Peter (referee)
The creation of electronic devices only from atoms or molecules could be the next step in the creation of more advanced nanotechnologies. Initial experiments have already taken place and we know that it is possible on some surfaces. In this work, we tried to create similar simple molecular structures on surfaces with a silicon substrate. We initially modified the substrate by depositing Bismuth, Indium and a combination of both. We optimized the methods of formation of these surfaces and subsequently created simple structures with the help of deposited Dithienyl- dithiopyrolopyrrole molecules, while we successfully managed to create the intended structures on several surfaces and arranged groupings of molecules on the surfaces Si(111)/In √3 x√7, Si(111)/Bi(√3 x√3) and on Si(111)/Bi-In(√7 x√7). We subsequently created a model of interaction molecules inthis structures on substrate
Analysis of political advertisements on Facebook before the parliamentary elections in 2021
Obergruber, Ondřej ; Křeček, Jan (advisor) ; Nečas, Vlastimil (referee)
The thesis is devoted to the analysis of Facebook advertisements, specifically political ones before the elections to the Chamber of Deputies of the Czech Republic in 2021. The theoretical part of the thesis is first devoted to political communication in general and its development, from which it moves on to a description of the current age of political communication. Next, the focus is on political communication through social networks and the technical means by which politicians communicate with users. The practical part consists of a quantitative content analysis of individual ads using Facebook's Ad Library tool and SPSS software. The results of the analysis are interpreted and placed in the context of the research, while answering the research questions of the thesis.
"You can't command a change of thinking": system of informal education for the elderly from the public policy perspective
Bílková, Kateřina ; Hejzlarová, Eva (advisor) ; Dobiášová, Karolína (referee)
This diploma thesis deals with the topic of non-formal education for senior citizens in Czech Republic from the perspective of public policy. The main goal of this thesis is to capture the current state, main challenges and key topics in the field of non-formal education for senior citizens in Czech Republic. The system of non-formal education for senior citizens represents a complex structure of institutions, which offer educational programmes and activities. Both the system and the senior population are immensely diverse, which, on one hand, offers a high degree of flexibility and autonomy to both, the participants and the institutions. But on the other hand, it presents a challenge for public policy to capture the complexity of the phenomenon, whilst maintaining inclusivity. The non-formal education for senior citizens isn't defined by the legislative and the field therefore falls under three different departments: Ministry of Education, Youth and Sports; Ministry of Labour and Social Affair and Ministry of Culture. Due to the aforementioned diversity, the research uses qualitative study design and is carried out through expert interviews and the analysis of public policy documents. The sample of experts is designed to capture the experience of all types of institutions, which offer some form of...
The role of women in non-violent protest movements: the case of Belarus
Andrychuk, Gabrielle ; Karásek, Tomáš (advisor) ; Kazharski, Aliaksei (referee)
Throughout the summer of 2020, Belarus received extensive international media coverage of its non-violent demonstrations arising in response to the disputed re-election of Alexander Lukashenka and the violent crackdown against protestors. This period of civil unrest was marked by demonstrations attended by a broad cross-section of citizens, many waving nationalist red and white flags. Rainbow flags, symbolic of the LGBTQI+ community, were also featured in the protests. This piece examines gender and LGBTQI+ politics in the context of the Belarusian 2020 non-violent movement. A feminist framework is applied to examine how essentialist gender binaries, hegemonic masculinity, and violence are propagated by the Lukashenka regime to negatively impact women's political participation and legitimize violence directed against LGBTQI+ people in Belarus to maintain control. In problematizing anti-LGBTQI+ rhetorics in Belarus it will be shown how political discourses are disseminated through hegemonic masculinity and have been employed to maintain a patriarchal and heteronormative status quo in Belarus. The research highlights the diverse ways that LGBTQI+ people have participated in the movement and addresses the violence that has been legitimized against LGBTQI+ at the protests and in detention.
