About identification of motor predispositions in triathlon
Kovářová, Lenka ; Bunc, Václav (advisor) ; Čepička, Ladislav (referee) ; Zháněl, Jiří (referee)
Title: About identification of motor predispositions in triathlon Aims: The aim of our study was to find and verify appropriate indicators predicting the on-coming performance in a short triathlon and determine their level for the junior category. Methods: In our study, we combined quantitative and qualitative approaches with a predominance of quantitative methods. In the first phase of the research, we used quantitative methods, confirmatory factor analysis for verification of models of predispositions and elaboration of performance standards for individual tests by means of T-points. In the second part of the research, we used the qualitative method (casuistic studies) to validate the test battery and its application in practice. Results: We have compiled a structural model of motor predispositions for short triathlon, which explained 91% of all cross-correlations of seventeen used indicators. Predispositions for triathlon were categorized into five separate groups; for swimming, cycling and running (i.e. according to individual disciplines), and functional and psychological predispositions. Finding a lower limit boundary of performance in the completed tests is considered to be the most important issue for the assessment of future performance in triathlon. As a lower limit we have set the zone...

External causes of death - regional differences and context in districts of CZ
Spilková, Zuzana ; Daňková, Šárka (advisor) ; Mazouch, Petr (referee)
This diploma thesis analyzes mortality from external causes in the region of CZ between 2014 and 2018. The main focus is on external causes of death as a group, suicide rates, and mortality from traffic accidents. Another aim of this thesis is, besides the description of mortality from external causes, to identify regional correlation and differences in mortality from external causes and selected causes of death (suicides and traffic accidents). This study uses correlation, factor, and cluster analysis. Because of the low numbers of deaths in the case of women (in all dependent variables), the study analyzes mortality from both sexes together. Based on created factors clusters of regions are developed. Results show the difference between regions in CZ in mortality external causes. Regions also vary in suicide mortality rates and traffic accident mortality rates. Independent variables that correlate with mortality from external causes vary for external causes as a group, for suicides, and for mortality from traffic accidents. Keywords: external causes of death, suicides, traffic accidents, factor analysis, cluster analysis

Self-harm in children
Tvrdoňová, Anna ; Procházková, Jana (advisor) ; Sotáková, Hana (referee)
Title: Self-harm in children Abstract This thesis deals with the topic of self-injury of adolescents. Its goal is to analyze the adolescents' view of self-injury, how the youth themselves define self-injury and what they perceive to be self-injurious behavior. The work is divided into two core parts. The first section focuses on the definition of the self-injury and reviews both current Czech and international literature. Particular attention is devoted to the inconsistent terminology, definitions and presentation of the recent classification system of self- injury. The second part is devoted to the research of explorative character. The data have been collected through a survey using anonymous self report questionnaire from 73 pupils between the ages of 13-15 and they were analysed using categorization and the method of factor and cluster analysis. Factor analysis extracted ten factors which served as the meaningful units and can be interpreted as adolescents' viewpoints of self- injury. Findings suggest the adolescents consider not only direct destruction of one's own body as example self-injury but also behavior that indirectly leads to negative health outcomes (eating disorders, smoking, abuse of alcohol). Interestingly, the youth reported ambivalent viewpoint of self-injury. They reported not only the...

Verification of rhythmic abilities of university students in the field of education and physical education and sport
Kašparová, Alena ; Novotná, Viléma (advisor) ; Pelclová, Jana (referee) ; Kyselovičová, Oľga (referee)
The thesis is focused on creating a test battery for the sense of rhythm assessment for university students in the field of Physical Education and sport. Music-sports practice lacks such tests and so far it is forced to use only tests designed for the music field. The structure of the new tests corresponds to the characteristics of the sense of rhythm from the point of view of music psychology. The tests are divided into three sections, which are Perceptual Skills and Activities (items 1 to 18), Reproductive Skills and Activities (items 19 to 27) and Production Skills and Activities (item 28). The Classical test theory (factor analysis) and Item response theory (two-parametric model) were used for the statistical processing of results. The methods also included the calculation of the reliability and validity of the test. The expected refusal of the proposed hypothesis was confirmed in both the classical test theory and item response theory. The exception was model 4, whose fit indexes, especially TLI = 0.537, showed a lack of evidence for the refusal of the hypothesis rather than for a perfect fit of the model with the data. The aim of the research was to compile and test models whose conformity with the data would be the best. The most favorable conformity was for model No. 1 and No. 5. Model 1...

Influence of the surface hydrophobicity and charge of the molecule for drop coating deposition Raman spectroscopy
Bura, Radek ; Kočišová, Eva (advisor) ; Procházka, Marek (referee)
Raman spectroscopy is an optical vibrational spectroscopic technique suited for a study of biomolecules and their interactions. In contrast to classical Raman spectroscopy, Drop-Coating Deposition Raman spectroscopy (DCDR) enables due to a preconcentration of the sample dried on a special hydrophobic surface to acquire a high-quality spectrum even in case of low concentrated samples. In collaboration with Department of Macromolecular Physics of the Faculty of Mathematics and Physics at Charles University, the three special surfaces - substrates - with different wettability (hydrophobicity) and roughness on the basis of silvers nanoparticles have been prepared. Solutions of methylene blue and glutamic acid at different concentrations and pH were dropped on these substrates. Nanoparticles size was determined. It was shown, that with increasing number of sputtered nanoparticles, the roughness of the substrates increased also. More roughened substrates show a higher static contact angle. The dynamics of droplet drying and the preconcentration of substances in the dried deposit were monitored. The preconcentration was assessed from the first subspectrum obtained from a factor analysis performed on series of measured Raman spectra from dried deposits. There was none among the substrates on which there would...

Exploring structural changes of employment in rural Czechia: territorial approach
Čapkovičová, Andrea ; Jančák, Vít (advisor) ; Květoň, Viktor (referee) ; Konečný, Ondřej (referee)
The thesis searches for driving forces behind structural changes of rural employment in the example of Czechia subject to changing rural paradigm and the related question of rural economic viability represented by the employment performance. The research elaborates on the territorial approaches which categorises regions according to their degree of rurality. In addition, the detailed classification is made according to the change of non-agricultural employment in the period 2001-2011 in order to identify dynamic regions which showed performance above national average (leading) and those which lacked behind (lagging). The observations prompt the question why is the performance differentiated. Therefore, the regionally differentiated impact of processes such as deagriculturisation, deindustrialisation and tertiarisation in the period 2001-2011 is analysed by the use of analysis of components (namely shift-share analysis) and multivariate analysis (namely factor and cluster analysis). The thesis aims to provide answers in particular by giving a thorough analysis of how the changing rural paradigm (and regional theories in wider context) conceptualise the driving forces behind employment development in rural areas. The added value is in the analysis of interrelations and correlations of chosen...

Psychosocial determinants of emotional intelligence among police officers in Czech Republic.
HYPŠOVÁ, Petra
The bachelor thesis deals with possible relations between psychosocial determinants and emotional intelligence of members of the Police of the Czech Republic. The theoretical part describes the emotional intelligence, the five-factor personality model and the psychosocial determinants of emotional intelligence among the members of the police. The empirical part aims to calculate how many factors create emotional intelligence measured by the SEIS questionnaire. The next goal is to compare whether there are differences in overall emotional intelligence and its factors between the Police of the Czech Republic and the general population. Considering the police, there the relationship among demographic characteristics and personality traits (measured by the NEO-FFI questionnaire) are investigated along with overall emotional intelligence. The research sample consists of a total of 531 respondents aged 18 and over. The research group is divided into the Police of the Czech Republic (N = 222) and the general population (N = 309). The results of the research did not prove the existence of a statistically significant difference between the Police of the Czech Republic and the common population in total emotional intelligence. However, a significant difference was found in the factor of understanding one's own emotions and emotions of other people and the factor of using emotions to solve problems between the Police of the Czech Republic and the general population. No statistically significant difference was revealed in the factor of the regulation of one's own emotions and of other people. No significant differences or relationships were found among age, education and gender of police officers and their overall emotional intelligence. An important finding, however, was to find relationships among all the personal dimensions according to the Big Five and the overall emotional intelligence of members of the Police of the Czech Republic.

Hedonistic motivations for shopping - scale localization
Ježek, Michal ; Remr, Jiří (advisor) ; Hendl, Jan (referee)
(abstract) The thesis deals with motivations for hedonistic type of shopping with a focus on their measurement by using a multidimensional scale designed and validated by Mark J. Arnold and Kristy E. Reynolds in 2003. This tool contains six constructs for which the author examined their transferability to the local environment of Czech consumers. The aim of the thesis was to convert the scale into the Czech language and into the context of the Czech consumers and their shopping behavior. There were analyzed cognitive interviews, which were focused on the understanding of the statements on the scale and their adjustment for the following questionnaire survey. This was conducted on a representative sample of the Czech internet population. Furthermore, statistical analysis was carried out with the focus on reliability and validity of the translated scale. Although the research does not primarily aim at creating a typology of shoppers or describing in detail the characteristics of Czech consumers, the results of the analysis indicate that Czech population's thinking about shopping is quite like of consumers in collectivist societies. At the end of the thesis, the final and modified scale is introduced containing five constructs instead of the original six. This instrument has been shown to be...

Bayesian factor analysis
Vávra, Jan ; Komárek, Arnošt (advisor) ; Maciak, Matúš (referee)
Bayesian factor analysis - abstract Factor analysis is a method which enables high-dimensional random vector of measurements to be approximated by linear combinations of much lower number of hidden factors. Classical estimation procedure of this model lies on the cho- ice of the number of factors, the decomposition of variance matrix while keeping identification conditions satisfied and on the appropriate choice of rotation for better interpretation of the model. This model will be transferred into bayesian framework which offers the usage of prior information unlike the classical appro- ach. The number of hidden factors can be considered as a random parameter and the dependency of each measurement on at most one factor can be forced by suitable specification of prior distribution. Estimates of model parameters are based on posterior distribution which is approximated by Monte Carlo Markov Chain methods. Bayesian approach solves the problem of selection of the num- ber of factors, the model estimation and the ensuring of the identifiability and the interpretability at the same time. The ability to estimate the real number of hidden factors is tested in a simulation study. 1
