Vybrané vlivy na reprodukci dojnic u stáda holštýnského skotu
BENEŠOVÁ, Dominika
Even though the Czech Republic average values of fertility indicators have improved in previous years, their maximum values are still exceeded in individual farms. This bachelor's thesis dealt with the evaluation of selected influences on the overall level of reproduction in the Holstein cattle herd. The aim of my work was to develop a literature review on the reproduction of cow reproduce. The literature review concerned their reproductive indicators, repro-ductive management together with methods of controlled reproduction and the main factors that influence the reproduction ability of a given dam. Another stated goal of this work was to evaluate selected factors that influence their reproduction in a se-lected herd of Holstein cattle. The analysis of fertility indicators and selected influ-ences took place on the Hadačka farm, belonging to company Kralovická zeměděská a.s. 242 cows of Holstein cattle or their hybrids were included in the monitored group, these selected dairy cows met the following criteria: they calved for the first time from 2019 to 2022 and at the same time were admitted, pregnant and calved in this defined time. The following fertility indicators were analyzed in chosen breed: length of ser-vice period, length of insemination interval and length between-calving interval. Sub-sequently, these selected indicators were evaluated depending on lactation order, daily and average daily milk yield, age at first calving and breed. As the lactation phase increases, the period of reproductive indicators is short-ened. The shortest period of fertility indicators (service period -68 days, insemination interval -68 days, calving interval -365 days) was showed by dairy cows in the 5th lactation, and the longest service period (107 days) by dairy cows in the 1st lactation, insemination interval (71 days) for the 3rd and 4th lactation and calving interval (390 days) in dairy cows for the 2nd lactation. Regarding the influence of daily milk and average daily milk yield, it was found that the shortest service period and insemination interval were analyzed in dairy cows with the largest daily milk (46-60 l) and average daily milk yield (56-65 l). On the contrary, the shortest calving interval was found for both daily (8-20 l) and average daily milk (11-25 l) in dairy cows with the lowest value of the milk production. In connection with the age at the 1st calving, it was determined that the shortest time of service period (98 days) and calving interval (380 days) are showed by dairy cows that calved for the first time at an earlier age (636 to 710 days, respectively at 21 to 23 months). On the contrary, the shortest time of insemination interval showed by heifers that calved for the first time at a later age (787 to 950 days, 25 to 31 months). The longest time of service period and calving interval are achieved by heif-ers that calved at the latest age (787-950 days). Comparing fertility indicators between purebred animals and their hybrids, pure-bred animals showed a longer service period (by 2 days) and insemination interval (by 0.5 days). On the contrary, the longest calving interval is shown by hybrids (387 days), which is 9 days longer than that of purebred animals (378 days).

Factors associated with discrepancy between self-rated and other-rated attractiveness
Benešová, Dominika ; Štěrbová, Zuzana (advisor) ; Třebický, Vít (referee)
Self-rated attractiveness plays an important role in person's well-being or mate choice. In some individuals, their self-rating doesn't match how they are rated by others, which can be a sign of their overrating or underrating. This bachelor thesis presents mechanisms, which can lead to the discrepancy between self-rated and other-rated attractiveness as well as individual factors which moderate the degree of this discrepancy. Theoretical introduction firstly describes general mechanisms which lead to the discrepancy in self- rating on the level of motivation, cognition and emotions. Then it presents biases that emerge in own body perception. Subsequently, it summarises the findings of previous research on the discrepancy between self-rated and other-rated attractiveness. The last part focuses on psychological factors, that can be associated with different degrees of this discrepancy. This thesis also contains a research proposal that builds on the theoretical introduction and its main aim is to test hypotheses about the role of presented individual factors (self-esteem, narcissism, body dissatisfaction) in the degree of discrepancy between self-rated and other-rated attractiveness. Empirical evidence explaining the origin of this discrepancy is currently very limited. Therefore, possible new...

Pragmatic aspects of speech communication at the elementary school
Benešová, Dominika ; Chejnová, Pavla (advisor) ; Palkosková, Olga (referee)
Communication skill is one of the key competencies that pupils should achieve during the compulsory education. The subject of this work - teaching pragmatic aspects is closely related to communication competence. The thesis focuses on teaching of pragmatic aspects in primary schools. Based on the theoretical literature there are defined basic terms such as cooperative communication, politeness principle, manipulation, argumentation, nonverbal communication and assertiveness. In the practical part the thesis focuses on the analysis of textbooks - how are the pragmatic aspects included in the textbooks. Other part is concerned with the analysis of the survey in which several teachers were asked about how the pragmatic aspects of speech communication are taught and how well is this subject matter mastered by their pupils. The last section includes worksheets, in which the activities are designed to practice examined pragmatic aspects.
