Perception of individual variation in body odour in human adults
Fialová, Jitka ; Havlíček, Jan (advisor) ; Schaal, Benoist (referee) ; Stopka, Pavel (referee)
The thesis consists of two parts. The first part introduces the topic of human chemical communication and reviews current evidence on individual variation in human body odour and its perception. This part is framed by sexual selection theory. In the first chapter, the concept of the theory of communication is introduced followed by a discussion on the specifics of chemical communication. Next, the formation of individually specific body odour signatures with reference to skin glands, their volatile products and the subsequent metabolization by skin microflora is described. The next chapters are dedicated to selected interindividual body odour cues such as sex and kin recognition, genetic compatibility in genes of Major Histocompatibility Complex, and health and reproductive status in a mate choice context. Furthermore, interactions between perfumes and body odours are discussed. Finally, methods of body odour sampling are introduced and a rationale behind presenting individual samples or body odour blends is discussed. The second part is comprised of six scientific papers, specifically three reviews and three empirical studies. Review papers summarize factors affecting human body odour quality with emphasis on diet and affective states. The first text shows that human body odours contain cues to...

Christians in cyberspace
Škácha, Petr ; Vopřada, David (advisor) ; Bouma, David (referee)
Christians in cyberspace. The aim of this work is to find an answer to the question of whether it is possible to use cyberspace safely and for good, or whether cyberspace itself is bad and its use incorrect. The first part of the work is devoted to the rapid technological development of recent decades in general. The first chapter defines the concept of cyberspace. The second chapter will summarize the development of technologies related to cyberspace, mainly telecommunications technologies. The next chapters look at how this change and the spread of technology has changed the way people communicate, and describe the most important changes, both positive and negative. The second part of the work tries to introduce to the specific worlds of the inhabitants of cyberspace, to the communities that have emerged around the new technologies with different goals. At the same time, specific examples were selected, in which new facts can be seen in some way, which were previously not available at all, or only to a limited extent. The last, third part is then the core of this work, to which the first two parts lead. It first describes how the already mentioned development of technologies and changes in the style of communication affect the individual, what are the benefits and consequences for him, and...
