This dissertation thesis is focused on the research of role of symbols, especially graphic symbols (emblems, logos), in the process of region formation and in the process of shap- ing of regional identities. These aspects are studied in the context of Anssi Paasi's theory of institutionalization of region. The thesis discusses the use of symbols in the develop- ment of regions of different scales. The theoretical background of symbol research in the process of a region formation, as based on literature research, is later verified on an example of the analysis of symbols of the Liberec Region and the way they are used by various regional institutions. The Liberec Region is a suitable model area since it both represents a newly constituted region (after 2000), as well as it is already fully institution- alized. This region is also very heterogeneous from the point of view of the natural and cultural heritage. Regarding the settlement perspective, there are both areas inhabited continuously (traditional, "Czech" areas) and areas resettled after the WWII. In its first part, the thesis is devoted to evolution of regional geography. It briefly pre- sents how regional geography responded to paradigmatic changes, and how it gradually evolved into a "new" regional geography. Next, it discusses the concept...

Sympatric speciation has received much attention both empirically and theoretically. However, the contribution of sympatric speciation to biodiversity remains unclear. One piece missing from the speciation puzzle is the plausibility of sympatric ecological divergence of species through adaptation in polygenic traits. I consider an environment consisting of two niches, where one value of the trait is advantageous in only one niche, and vice versa. The selection regime is described by a trade-off in viabilities between the niches. These polygenic traits can, and often do, involve epistatic interactions among and between loci, so that the contribution of the alleles to viability deviates from additivity. Epistasis then also affects the curvature of the trade-offs: predominant less-than-additive epistasis turns the curve towards concavity and predominant more-than-additive towards convexity. The curvature of the trade-off plays a crucial role in the evolution of populations. With a convex trade- off, extreme values of the trait are favored and the population tends to diverge, but relatively stringent symmetry in strength of selection within the niches and the niche proportions is necessary to maintain polymorphism. In this study I use two and three- locus haploid versions of Levene's model to...

Presented diploma work called "Semiotic and anthropological analysis of Prague metro" shows metro to a reader as a place from a semiotic point of view. A metro "user" plays a key role in the whole diploma work. Apart from dealing with metro as a place, this work also regards a reference of a fixed structure of metro to a city. The work also pays attention to an analysis of signs that can be found there by a metro user and can serve him as a useful tool for better orientation there. In the theoretical part semiotics as a science and its approaches are being presented. The diploma work also deals with a topic of a city from an antropological point of view. It applies, for example, a question of place and nonplace, picture of a city or a map and itineraries. The applied part of the work presents use of the theory in Prague metro. It also deals with orientation, navigational sign systems and comunication systems. Other topic examined in this diploma work is a role of Prague metro and its city surroundings in a mental city mapping done by its user. Besides, the work shows the metro and its surroundings as a place of everyday life. Keywords: Semiotics, sign, communication, binary opposition, connotation, denotation, text, city, image map, places and non-places, place and space, map, itinerary, everyday...

This diploma thesis deals with alternative and augmentative communication systems using at the individuals with pervasive development disorders. Thesis is divided the theoretical and the experimental part. Theoretical part contains mainly informations about communication disability, speech development, diagnosis of communication abilities, alternative and augmentative communication systems and possibilities of aid to the families with child with pervasive development disorder. Experimental part presents research using questionnaire, which was send to the parents or legal representatives with child with pervasive development disorder. The research prepares base for next extensive researchs.

My diploma thesis is instalation, which elements are based on principales of ready-made. Documentation of living performance. Site-specific charakter, objects, and documents are common, that are one from of physical, psychical, and social injuries. Trought the installation and added text with its full range of form I am changing the discurse.
