Repeatability and personality in tests of exploratory behaviour
Žampachová, Barbora ; Frynta, Daniel (advisor) ; Sedláček, František (referee)
Personality, or behavioural differences among individuals, which are stable both in time and across contexts, is a highly popular topic. Currently there has been an increase of interest in the relationship between personality and repeatability, which is a methodical approach developed to measure the stability of interindividual differences in time. The aim of this thesis is to evaluate the personality of rats according to behavioural patterns exhibited under widely used testing procedures in new environment (open field test, hole board test) and to compare, how behavioural traits in these tests mutually correlate and change over time. Each test trial was repeated eight times with different intervals (24 hours, 6 days, 4 weeks). The results suggest that most of the recorded behavioural variability can be explained with three principal axes. The first one is associated with loco-exploratory activity of the subject. The elements of behaviour associated with this axis are the most repeatable. The second axis is mostly associated with time the animal spent in the central part of the arena and the third axis represents the interest in holes in hole board test. These two axes are less repeatable. A significant effect of the identity of the animal was found in all behavioural traits, associated with these...

Podobnostní vyhledávání obrázků na webu
Grošup, Tomáš ; Lokoč, Jakub (advisor) ; Hoksza, David (referee)
The subject of this bachelor thesis is to design and create a web portal, enabling efficient indexing and content-based searching of images obtained from various free image databases (e.g., results from a keyword-based search engine). The portal provides fast feature extraction technique and for the visual similarity, the signature quadratic form distance is utilized. The search supports various user settings and comparison of their results. Search results can also be presented using a layout based on particle physics, which supports exploration and multi-query.

Substance use among people with hearing disability: exploration and cerrelation probe
Postránecká, Zuzana ; Vacek, Jaroslav (advisor) ; Janíková, Barbara (referee)
Although there are about 500 000 of people with hearing impairment in Czech republic, a risk group of substance abuse due to determinants of this impairment, there are distinctive lack of studies focused on this theme in our state. There are few foreign studies offering some results, overall interest is still slender in this issue. This work was aimed to define the basic terms and briefly describe difficulties of hearing impairment, psychological aspects and patterns of drug use in hearing impaired population due to available resources and exploration and correlation questionnaire study. The study had a questionnaire form and was spread by snow ball method in first stage, through 8 basic subjects on social network called facebook.com and other forms of mass communication. In the second stage we used a purposeful selection at two schools for the hearing impaired in Prague. Participants were indviduals with more than 20 dB hearing loss (includes) in both cases. The participation was no age or locally restricted. The result of theoretical and practical part is a fact, that drug using in hearing impaired population is on the same or maybe even higher level like in intact population. Due to this fact and communication barriers of hearing impaired individuals, it is required to involve a specialized...

Exploration, neophobia and dietary conservatism in tits (Paridae)
Beranová, Eliška ; Exnerová, Alice (advisor) ; Fučíková, Eva (referee)
Neophobia and exploratory behaviour are two processes applied in great measure in birds' reactions towards novel stimuli. The specific demonstration of these two processes may differ between different species of birds as well as within them. We compared neophobia and exploratory behaviour in two species of tits (Paridae). Adult Great tits (Parus major) and Blue tits (Cyanistes caeruleus) did not differ neither in exploring novel environment and novel object nor in neophobia towards novel object near food. We have found great differences between juveniles of these two species. Juvenile Blue tits were more neophobic towards both novel objects. Age, sex and personality affected some differences within tested species. We tested whether there exist any differences in reactions towards novel food between and within species. We used red painted mealworm (larvae of Tenebrio molitor), house cricket (Acheta domestica) and aposematic bug (Pyrrhocoris apterus) as novel food. Adult wild-caught tits with plentiful experience with various feeds did not differ in reaction towards these types of novel food. In contrast hand-reared juvenile tits differed quite a lot. Juvenile Blue tits were more neophobic than juvenile Great tits towards all three types of novel food. We found dieraty conservatism, phenomenon...

The Assessment in Vocational Training by Vocational Branch Hairdresser
RŮŽIČKOVÁ ZAUMÜLLEROVÁ, Věra
The aim of this study is to evaluate students within the teaching process in accordance with a specified timetable in relation to the SEP, not only in general, but also specifically as an assessment of a student by a teacher during the vocational training for hairdressers. This work aims to define the basic concepts and briefly describe the problems of student assessment not only by a teacher but also by the student himself, including the evaluation of the performance of one individual student by other students. Furthermore, it aims to describe the psychological aspects and patterns as a result of the evaluation, both on the part of the teacher, the student himself, classmates, but also on the part of participants involved in the evaluation process. The work will have a theoretical - empirical character. The theoretical part describes the evaluation of the student by the teacher during the educational training with a focus to the vocational training for hairdressers in accordance with SEP. It describes a method of systematic observation of the student within the scope of the evaluation process, potential analysis and interpretation of the performance shown by the student and forms of expression of the evaluated results. The work also aims to take advantage of student self-assessment and involvement of peers in the evaluation process. The theoretical part also pays attention to the very concept of "hairdresser", a historical perspective on the notion and not least the current view on this vocational training, its classification and description. The empirical part will propose an assessment system for educational training of the vocational field and will experimentally verify the possibility of its use in practice. In the context of the experiment, sheets will be proposed for self-assessment of students, for evaluation of student performance by classmates and for assessment of the students by teacher. These sheets will be used within one half-year for assessment during vocational training. Result of the experiment is validated through evaluation questionnaires for students.
