Diplomová práce je zaměřena na rozdíly v nákupních chování napříč populací. Jednotlivé odlišnosti jsou hledány jednak před věkové skupiny a jednak přes pohlaví. Práci doplňuje praktický výzkum, který se skládá jednak ze sekundárního výzkumu této problematiky z provedených studií a jednak z provedeného asistovaného nákupu a dotazníkového šetření.

The aim of the thesis was to observe the mutual behavior between dogs in public spaces in Svitavy. A total of 250 pairs of dogs were monitored. I followed various aspects and their effects on the resulting behavior of the monitored dogs. I followed various factors, such as the age of the owner or the dog which first initiated sniffing. The results show that many factors have influenced social interactions, including the sex of the dog, the sex of the owner, or the way in which the dog is guided. I found that most of the other dogs started sniffing adult dogs and that the most sniffing place in all dog categories was the back. Most often, they urged dogs to play small breeds.

Kavoň, F. Consumer behavior when choosing a place for grocery shopping in Brno. Brno, 2019. Master thesis. Mendel university in Brno, Faculty of Business and Economics. The main subject of the thesis is the analysis of consumer behavior. The selected market for consumer behavior observation is the grocery market in Brno. The research uses two research methods, which include questionnaire, and focus groups. The result of this thesis is a proposal of marketing recommendations leading to sales promotion for entities operating in the selected market.

The aim of the diploma thesis was to study factors influencing behavior of dogs in public spaces in Brno. 133 pairs of dogs were observed. The dog's gender, dog age, and age of the dog owner affected the interaction. The owner of the dog affected by the interaction. The dog's sex, dog age, and dog age influenced sniffing. All factors that were monitored influenced the play. The gender of the dog affected the marking behavior. The gender of the dog owner affected the threat. The dog's owner's gender affected bite occurrence.

Allomaternal care is one of the most interesting types of cooperation among females. Its most extreme form is allonursing, nursing of a non-filial young, which is still not completely understood, even though many hypotheses have been postulated. This type of cooperation among giraffes had not been expected for long time. This was based on the initial opinion that giraffes do not have social system and form only weak social bonds. However, my bachelor and master theses showed high occurrence of allonursing in captive giraffes. The first aim (1) of this thesis was to test all possible hypotheses explaining allonursing in captive giraffes. However, a lot of the information needed to test them were missing, which resulted in the formulation of further aims. The second aim (2) was to test the hierarchy in captive giraffes. The third aim (3) was to describe the growth and weight of captive giraffes. The fourth aim (4) was to compare nursing patterns in the zoo and in the nature reserve Bandia, Senegal and the last aim (5) was to test the social bonds among giraffes in the nature reserve Bandia, Senegal. (1) From 2007 to 2011, the nursing behaviour of 24 females and 37 calves was observed. Eighty-three percent of the females allonursed a nonfilial calf and 86.5% of calves allosuckled from a nonmaternal female. Allonursing in giraffes was explained by milk-theft from the point of view of the calves and possible reciprocity among females. (2) The agonistic interactions of 31 giraffes were recorded in four herds. A linear hierarchy was been found among giraffes and rank was significantly affected by age and time spent in the herd. (3) The weight data from 43 giraffes in Prague zoo were collected from 2009 to 2013 and provided the basic information about giraffe growth and weight. (4) I also observed the nursing behaviour of seven and four female-calf pairs in the fenced Bandia reserve, Senegal, and in Prague zoo, respectively, both for 22 days. The differences in nursing patterns were likely to reflect anti-predator behaviour, the population density of animals and the distribution of food resources. (5) Finally, I investigated the social preferences of 28 introduced giraffes in semi-captivity in the nature reserve Bandia, Senegal and provided the results supporting the existence of a fission fusion social system among giraffes with social preferences among adult females. The overall results provide unique findings on allonursing in general as well as changing our perspective on giraffe social behaviour.

The goal of the dissertation was giving a view of behavioural disturbances that secondary school teachers may encounter. The essay then closely concentrates on truancy problems that teachers encounter very often. The theoretical part shows the difference between problem and defective behaviour and consequently common effects in certain development phases of a child contrary to behaviour that must be classified as defective. I will also state the classification of defective behaviour used by specialists in various fields. Following chapters will focus on explanation of truancy terms, its causation and possible arrangements to prevent skipping mandatory education. The practical part is created by interviews with secondary school teachers who encountered truants in their common practice. The goal is the analysis of the level of teachers' view on the problems. At the same time, I will try to reveal the teachers' approach to solving truancy, treating truants and their families.

This thesis addresses the relationships between beef cattle (Bos taurus) group behaviour on pasture, social dominance and individual characteristics such as body weight and age. The thesis is based on three studies performed in a herd of female beef cattle. In the first two studies, GPS collars were used as the main data-collection method, while the third study relied on an extensive dataset of cow dominance relationships. The first study focused on activity synchronization. We assessed whether cows similar to each other in body weight or in reproductive status were more synchronized and whether the timing of activity switches was determined by specific leading animals. We found that the body weight difference in a dyad of animals had a negative influence on their mutual synchronization. There were no leading animal initiating switches in activity. The second study focused on the role of dominant animals in group movements of the herd. There were positive correlations between dominance status of an individual and several measures of leadership during movements, namely the position of the animal at the front of the herd, more direct and shorter trajectories and higher alignment with nearest neighbours and with the whole herd. These results show that herd movements on pasture behaviour were...
