Personality differences in individuals of various sexual orientations
Fořt, Jakub ; Havlíček, Jan (advisor) ; Procházka, Ivo (referee)
The previous research identified a range of personality differences between men and women of various sexual orientations. Non-heterosexual individuals systematically show higher gender nonconformity and greater openness to experience than heterosexual individuals. Non-heterosexual men also show higher levels of neuroticism compared to heterosexual men. The main aim of this study is to replicate previous findings regarding personality differences. The study further aims to determine whether some of the observed differences in personality factors might be explained by differences in gender nonconformity among individuals of various sexual orientations. Via an online survey, a short version of the Big Five Inventory (BFI-10) and a number of scales measuring gender nonconformity were administered to men (N = 3,418) and women (N = 4,690). In total, 232 individuals identified as asexual, 1,814 as bisexual, 3,024 as heterosexual, 2,468 as homosexual, and 570 as pansexual. Our results demonstrate higher gender nonconformity among non-heterosexual men and women, higher neuroticism among non-heterosexual men, and greater openness to experience among bisexual men and women compared to heterosexual individuals. Asexual women showed lower levels of extraversion than women of other sexual orientations. Gender...

The role of the nutritional therapist for people living with HIV
Tomanová, Michaela ; Starnovská, Tamara (advisor) ; Procházka, Ivo (referee)
Nutrition is one of the prognostic, predictive and also modifiable risk factors for the development of civilization diseases, which unequivocally cause the highest mortality in our territory. Obesity, metabolic syndrome, cardiovascular disease, hypertension, and type 2 diabetes mellitus have been shown to progress earlier and more progressively among people living with human immunodeficiency virus (PLWH) rather than in the HIV-negative population. Thanks to the modernization of antiretroviral therapy (ART), the incidence of wasting or lipodystrophic syndrome among adherent individuals is very low, if not zero. However, HIV infection together with the ART and unhealthy lifestyle now represent a certain risk of undesirable comorbidities in the form of civilization diseases. The complex topic of nutritional care for PLWH should be part of the professional knowledge of every nutritional therapist. Questionnaire surveys intended for qualified nutritional therapists and educational institutions, which were applied for the first section of the practical part of this thesis, confirmed all formulated hypotheses. The result of this part is the finding of insufficient education and the absence of deeper knowledge in the field of nutrition for PLWH among almost 95 % of the interviewed nutrition therapists,...

Study of precipitation effects in Mg-Y and Mg-Y-Nd systems
Heteš, Michal ; Čížek, Jakub (advisor) ; Procházka, Ivan (referee)
The aim of this bachelor's thesis was to investigate the precipitation processes in the binary system Mg-Y and the ternary alloy Mg-Y-Nd using positron annihilation spect- roscopy and hardness testing, where we measured 2 samples with 3% and 6% by weight representation of Yttrium impurity atoms and 3 sample with 4% by weight representation of yttrium atoms and 3% by weight representation of neodymium atoms. The develop- ment of the hardness of the alloys was measured by the Vickers method of hardness measurement. Together with the hardness measurement, the characterization of crystal lattice disorders of the cloudy alloy samples was carried out using positron annihilation spectroscopy. It was measured that at higher temperatures hardening of the studied sys- tems occurs. Hardening was caused by the formation of GP zone precipitates and the β′ phase by Y, Nd and Mg atoms. 1

Low temperature polarized target for spin structure studies of nucleons at COMPASS
Pešek, Michael ; Finger, Miroslav (advisor) ; Procházka, Ivan (referee)
Title: Low temperature polarized target for spin structure studies of nucleons at COMPASS Author: Bc. Michael Pešek Department: Department of low temperature physics Supervisor of the master thesis: prof. Ing. Miroslav Finger, DrSc. Abstract: In presented thesis we describe concept of Deep Inelastic Scattering of leptons on nucleons in context of nucleon spin structure studies. Both polarized and unpolarized cases are discussed and concept of Transverse Momentum Dependent Parton Distribution Functions (TMD PDF) is introduced. The possibility of TMDs measurement using Semi-inclusive DIS (SIDIS) is described along with related results from COMPASS experiment. The future Drell-Yan programme at COMPASS is briefly mentioned and its importance is presented on the universality test i.e. change of sign of T-odd TMDs when measured in Drell-Yan and SIDIS. The importance of Polarized Target (PT) for spin structure studies is highlighted and principles of Dynamic Nuclear Polarization (DNP) are given using both Solid effect and spin temperature concept. COMPASS experiment is described in many details with accent given to PT. Finally the thermal equilibrium (TE) calibration procedure is described and carried out for 2010 and 2011 physics runs at COMPASS. The average polarization measurement results from 2010 and 2011 are...

Parent's coping mechanisms with the descendant's transsexualism
Gregorová, Pavlína ; Weiss, Petr (advisor) ; Procházka, Ivo (referee)
This thesis deals with parental coping with the transsexualism of their offspring. A questionnaire containing 66 items was created for this purpose. 16 parents of transsexual offspring participated in the research (12 mothers, 4 fathers). Just two offsprings were MtF, the others were FtM. 11 parents were contacted via their transsexual offspring, four parents were addressed at while attending a psychotherapeutic group for parents of transsexual offsprings and one parent filled in the questionnaire placed on the Internet. We found out that the most difficult situation for the parents was the moment their transsexual offsprings announced their transsexualism. A majority of the parents were in the state of shock and a majority also felt sorry. After that, the relation between the parents and their transsexual offspring improved. The parents evaluated the current relation between them and their transsexual offspring as sufficiently good. The person who helped the parents most to cope with the transsexuality of their offspring was his or her spouse, however in most of the cases nobody actually helped the parent. The majority of the parents managed to cope with the transsexuality of their offspring within one month. Data analysis showed that almost all parents, who participated in this research, have already...

Rationality of the Debtor
Procházka, Ivan ; Tuček, Milan (advisor) ; Kuchař, Pavel (referee)
This work deals with the indebtedness of consumers. It examines the causes of the debotrs themselves. Based on a secondary analysis of past research in the area of financial literacy, consumer behavior, statistical data, but also of qualitative research in the form of case study seeks to answer the question why the debtor becomes the debtor, the extent to which the indebtedness and indebtedness viewed as rational behavior but also if the debtor is accompanied by rational reasoning or irrational behavior. It concludes that the debtor can not be considered entirely rational. Applied policy then the issue of over-indebtedness problem takes into account the irrational assumptions by the debtor only marginally and does not reflect as one of its main causes.
