Sociální vztahy a synchronizace ve stádech přežvýkavců - vliv na pastevní chování
Šárová, Radka ; Špinka, Marek (advisor) ; Červený, Jaroslav (referee) ; Nekovářová, Tereza (referee)
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...

Behaviour of Employees' Satisfaction in a chosen Organization
Bělohlavová, Martina ; Vinšová, Tereza (advisor) ; Šťastný, Jan (referee)
The dissertation is about employees' behaviour in the middle-sized organization. The theoretical part at first focus on individual behaviour and influences that determine this behaviour in the organization. The next theoretical part is focused on the group behaviour, working relationships and mentioned also the role of the manager. The Practical part analyses the chosen organization, where the survey was made and comes with the conclusions for the management and the organization.
