Sex chromosomes in the house mouse hybrid zone
DUFKOVÁ, Petra
Understanding the genetic basis of reproductive isolation is the ultimate goal of the study of speciation. Here I present the results of a study of gene flow and its barriers at sex chromosome markers across the central European portion of the hybrid zone between two house mouse subspecies, Mus musculus musculus and M. m. domesticus. We identified strong introgression of Y musculus chromosome into the domesticus area accompanied by a perturbation of the census sex ratio. In addition, we detected stochastic effects that can distort results of hybrid zone studies. Finally, we confirmed a strong effect of sex chromosomes on reproductive isolation and hence their important role in the process of speciation.

The Role of Non-human Actors in the Construction of Scientific Fact in Bruno Latour's Conception
Patáková, Markéta ; Horák, Vít (advisor) ; Hlaváček, Karel (referee)
The main topic of this thesis is the construction of a scientific fact as a special case of construction of reality. Bruno Latour is connected to this in several perspectives through which will this thesis capture his position. It describes his concept of science, originating from his laboratory studies, and its later embedding under the actor-network theory. In both cases, the emphasis lays on withdrawal from explanation through complex invisible forces, used by contemporary sociology. Latour refuses to explain a scientific fact through reference to outside world and society. According to him, attention should shift to the local and empirically approachable level. On this level there are collectives of human and non-human actors, who act together. Latour's conception of the construction of a scientific fact is put to test by the critique from sociology of knowledge. The strong program of sociology of knowledge understands the scientific fact as a joint product of reality and society. Non-humans (principally laboratory technology) play a key role in this dispute. Sociology of knowledge does not include them in their analysis, because they are not taken as social actors. Technology is on the other hand a core element in the construction of scientific fact in Latour's conception. Readers of this thesis will...

The process of constructing social status during transition to new classroom
Brožová, Martina ; Horáková Hoskovcová, Simona (advisor) ; Čáp, David (referee)
The aim of the research was to describe and understand the process of constructing social status during transition from elementary school to high school. The theoretical part focuses on the classroom as a social group, there is described the social structure of the classroom, as well as the most common roles and sociometric positions that occur in the classroom. There are also discussed relevant topics about adolescence and possible ways for exploring social relations within the classroom. In the empirical part I present a qualitative research, in which have been involved five high schools from Prague and its surroundings, N= 104 students. For this purpose two questionnaires were used - sociometric rating questionnaire SORAD and questionnaire mapping experience of the individuals in interpersonal relationships and their satisfaction with the change of the school community. Based on data analysis and interpretive methods, I conclude that social status is constructed in the earliest interactions between members and there is only a little variability. Social status is made up of two categories - relational skill, which is expressed by popularity, and social force, that is expressed by the ratio of power in the group. Competence complements these two categories, this is a specific skill and it's...

Internet in activating czech extremist far right movements
Miňovská, Veronika ; Rataj, Jan (advisor) ; Dlouhý, Miloš (referee)
The primary focus of this Master's thesis is the role of Internet and above all various social networks in activating Czech extremist far right movements. The thesis analyses the way modern means of communication streamline the spreading of socially marginal ways of thinking and the way these technologies help bypassing the media blockage often imposed on the activities of these movements, as well as the repressive police force, the power of which is circumscribed within the partially anonymous realm of Internet. A part of this work is also dedicated to an ideology based categorisation of the various branches of right wing extremists. This division is then supported by specific quotes published by these groups on the Internet. The groups that are given the most prominence include the Workers' Party of Social Justice, the Workers' youth, the National Resistance and the Autonomous nationalists.

Economic impacts of displacement of Sudeten Germans in the Karlovy Vary region
Černý, Robert ; Szobi, Pavel (advisor) ; Kozmanová, Irena (referee)
This bachelor thesis deals with the impact of forced displacement of German population on economic development of the Karlovy Vary region after the Second World War. Preliminary, the author weights up the role of Sudeten-Germans in the region in 1918--1945. Afterwards, he focuses on transfer of German-speaking inhabitants from the region after resumption of the Czech Republic. This thesis analyses immediate consequences of changes in the structure of population. It makes use of examples such as disappeared borderline communes, closedown of Sudeten-German companies or their nationalisations. Onward, this writing follows the inefficient level of workers in economically important professions as well as changes in social structuring of society and its standard of living. This thesis draws particularly from archival documents such as State provincial archives Karlovy Vary and Sokolov resident in Jindřichovice as well as unpublished sources of private provenience (recollections, memoirs) and chronicles of described communes in the Karlovy Vary region.
