Minors' Experience Analysis of Romanticized or Sexualized Contact with an Educator
Mašková, Kateřina ; Onder, Jakub (advisor) ; Krejčí, Josef (referee)
The diploma thesis deals with the issue of romanticized and sexualized contact of minor students and their adult educators which is being dominantly silenced in the Czech Republic. The thesis consists of a theoretical part and an empirical part. Theoretical part of the thesis presents psychological aspects of the developmental period of adolescence and of the pedagogical profession, discusses the issue of crossing professional boundaries by an educator and finally defines a specific subtype of educator sexual misconduct: educator sexual abuse of minor students in the form of a mutual sexualized type of a contact. The focus of the empirical part of the thesis is a research project framed by constructivist ontology, feminist epistemology and phenomenological metodology. The research project is an interpretative phenomenological analysis of the experience of five adult women who experienced romanticized or sexualized contact with their educator during adolescence. The purpose of the research was to gain an in-depth understanding of its participants' experiences both from their former adolescent perspective and their contemporary adult perspective and to capture any possible change of their mind during the given period concerning their own experiences. Currently, all five research participants consider...

Abstinence among young adults
Dočkalová, Barbora ; Krejčí, Josef (advisor) ; Chrz, Vladimír (referee)
Based on current research and yearly reports of consumption of addictive substances where the Czech Republic repeatedly ends up at the top of the rankings while also having fewer people who abstain from addictive substances in comparison to European standards, we've decided to understand more about the experience of people who abstain. So far the research wasn't too focused on the people who abstain from addictive substances therefore the aim of this work is to get a holistic perspective of their lives. A group of young adults who have been abstaining from addictive substances for some time and therefore can reflect on their experiences have been selected as participants in the study. Fifteen different experiences with abstinence have been collected through semi-structured interviews. The first phase of data analysis (Analysis I) reviews and compares the responses, and in the second phase (Analysis II) we've worked with the central category that is common among the interviews. Psychological resilience has been established as a strong common basis among all respondents which represents a supportive factor against conformity to a society that has different patterns of consumption of addictive substances than respondents. In the final section of the thesis, we've suggested a dynamic model of factors...

Midlife crisis from the perspective of psychotherapists: interpretative phenomenological analysis
Žochová, Kateřina ; Chrz, Vladimír (advisor) ; Krejčí, Josef (referee)
The thesis deals with the experience of psychotherapists with the midlife crisis in their clients. The theoretical part deals with the midlife crisis and selected psychotherapeutic approaches. The empirical part is based on qualitative research and is realized by the method of interpretive phenomenological analysis (IPA). The research included three semi-structured interviews with psychotherapists who differ in theoretical orientation, namely Gestalt, SUR, and Pesso Boyden. The aim of the research was to understand the specific experiences of psychotherapists with the midlife crisis and whether their perception of these experiences corresponds to the psychotherapeutic approach. Elements from the narrative approach in the research were used in the data analysis. The results are summarized in a discussion, where they are also processed together with theoretical concepts and selected research. Based on this research, it was found that all three psychotherapists agree that there are increased changes between the ages of 40 and 50, which can result in some of the symptoms often referred to as midlife crisis, but in explaining the nature of the problems are significantly different. To some extent, we can say that their perception of the concept of the midlife crisis is influenced by the chosen...

Resilience in the elderly in the Institute for visually impaired "Palata"
Bozděchová, Kristýna ; Chrz, Vladimír (advisor) ; Krejčí, Josef (referee)
The goal of this thesis is to understand and map how elderly people cope with adversity that this stage of life unavoidably brings with it. The first part of the thesis - the theoretical background, is based on literary sources that try to define concepts like "resilience", "old age", "institutional care for the elderly" and "visual disorders". The empirical data has been obtained through semi-structured deep interviews with four selected clients of the Retirement home för visually impaired people "Palata". The evaluation of the data has been done thanks to the qualitative approach of the interpretative fenomenological analysis that helps us comprehend how a person creates meaning of one's lived experience and thus understand the individual point of view on subjective experiences. The interviews have enabled us to define the categories that have appeared most frequently and represent a significant source of mental resilience - family, social interactions, display of gratitude towards staff, responsibility/external support, acceptance/satisfaction, moral values, leisure activities, accentuation of small life events and integrity. These categories have been described in more detail based on specialized literature. As a conclusion we have summarized the major findings from our interviews and literary...
