Asset Pricing and Portfolio Selection via Machine Learning
No full textThis thesis consists of three papers investigating stock returns forecasting, empirical asset pricing, and portfolio selection through the application of machine learning and quantitative methods. The first paper examines out-of-sample returns on 153 documented anomalies in equities, demonstrating that machine learning techniques, which aggregate these anomalies into a single mispricing signal, are profitable globally and effective even within a liquid universe of stocks. Notably, while past performance of quantitative strategies outside the U.S. does not reliably predict out-of-sample success within the U.S., U.S.-based evidence is broadly predictive of returns in international markets. The second paper introduces a novel method for predicting the full distribution of stock returns using a comprehensive set of 194 stock characteristics and market variables. This approach, free from restrictive model assumptions, leverages a two-stage quantile neural network with spline interpolation to explore non-Gaussian, heavy-tailed data and their non-linear interactions. The results indicate that this method outperforms traditional models in terms of out-of-sample losses and provides valuable alternative empirical estimates for mean estimation and forecasting across a wide range of U.S. and international..

I will forget when the moss falls. Transgenerational transmission of trauma and family relationships
No full textThis work focuses on the transgenerational transmission of trauma in the context of art therapy, with a particular emphasis on war trauma and trauma associated with the Holocaust. The theoretical part of the thesis is structured into several key chapters, addressing topics such as trauma, the impact of trauma on families, transgenerational transmission, and (art) therapeutic approaches to treating these psychological challenges. The practical part examines the artwork of children from Terezín and adult survivors, aiming to identify common artistic characteristics that may also be present in the work of second-and third-generation descendants. The final section of the thesis explores whether the trauma experienced by ancestors manifests symbolically in the artistic expression of subsequent generations. Additionally, it considers potential parallels between two individuals of the same generation who share similar historical burdens
Volleyball as a freetime activity
No full textThis bachelor thesis examines the influence of family environment on the relationship to sports, specifically volleyball. The key question of the study was: "What is the relationship of a volleyball family to sport and how does this sport influence their daily life?" The partial objectives were to determine how family background affects motivation for sports and what role it plays in shaping attitudes towards physical activities. The study was conducted through unstructured interviews with three members of one sportsoriented family. The results showed that volleyball significantly influences their daily lives, family relationships, and mental well-being. Key factors were identified as parental and coaching approaches, team atmosphere, and positive motivation. The study emphasized the importance of a balanced approach without excessive performance pressure. These findings can be beneficial for coaches and parents of young athletes
Geochaching as a leisure activity of older adults: benefits and limits
No full textThis bachelor's thesis examines geocaching as a leisure activity for seniors, focusing on its benefits and limitations. The aim is to analyze how geocaching impacts seniors' lives and in which areas they perceive enrichment. The study considers physical, mental, social, and technological aspects of this activity. The research is based on a qualitative approach, using semi-structured interviews with seniors actively participating in geocaching. Respondents highlighted the joy of outdoor movement, discovering new places, and engaging with the geocaching community. For many, geocaching serves as both a recreational pursuit and a means to maintain an active lifestyle despite age-related physical limitations. While some found the technological aspects challenging, most adapted over time. The findings suggest that geocaching can support active aging by offering a meaningful pastime and reducing feelings of loneliness
Fear of a child with a disability in the group
No full textThe topic of this thesis is the manifestations of aggression in a child with a disability in a group of preschool children and their coping. The thesis consists of two parts, theoretical and practical.

Mapping of protected sites in the selected region
No full textThis bachelor thesis focuses on the mapping of protected sites in the Třeboňsko Protected Landscape Area (PLA). The main objective was to identify and document selected strictly protected areas, namely the National Nature Reserves Velký a Malý Tisý, Stará a Nová řeka, Červené blato, and Žofinka. The documentation included original field photography and a comparison of the current condition of these sites with historical orthophotos. Mapping and spatial analyses were conducted using the ArcGIS geographic information system. The outcome includes a set of thematic maps, photographic documentation from fieldwork, and an assessment of landscape changes over time. These results contribute to a better understanding of the development of protected areas and support their future conservation
