Vliv frekvence genotypů prionového proteinu na reprodukční a produkční vlastnosti ovcí v ČR
Žváčková, Pavla
The aim of the diploma thesis was to find out how the frequency of the prion protein genotypes affects the production and reproductive characteristics of sheep in the Czech Republic. We also used graphs to evaluate changes in the frequency of allele of prion protein genotypes from 2003 to present in ten selected breeds of sheep genotyped within the breeding program for scrapie resistance in the Czech Republic. We also dealt with administrative interventions in the genotyping process by the state and recognized breeders' associations. In the next part we evaluated the changes in the frequency of the allele in relation to the development of the sheep properties in the Czech Republic. The results of the research were processed by appropriate mathematical and statistical methods. We have found that the sheep production properties are influenced by the allele frequencies of the prion protein genotypes, and that administrative interventions have contributed to changes in the frequencies of the risk groups in some breeds. Further, we have discovered that most of the highest values of utility properties are associated with the risk group R1.
Measurement of (anti)immigration Attitudes from the Methodological Perspective. Quality of Measurement with the Special Focus on Measurement Equivalence
Šarapatková, Anna ; Remr, Jiří (advisor) ; Soukup, Petr (referee)
Opportunities that we have in today's world are sharply evolving, and the world is changing all together with these changes. This development is noticeably observed within the topic of global movement of (not only) population, which has changed fundamentally, both economically, politically and socially. Today's so much diversified form of migration, which has lost its transparency it used to has, is a very up to date and debated topic currently almost all over the world. Because of high importance of the topic "migration" it is often subject of research and number of surveys. One of the most examined area within the topic migration is attitudes of people towards immigration and immigrant, oftentimes together with investigating cause leading to particular attitude. Due to the international reach of the topic, these attitudes are often subject of cross-national research or national research, which, however, use data from international surveys. There is a clear disparity across European states in these attitudes towards immigration and, above all, the immigrants themselves. Given this nature of cross-national surveys measuring attitudes towards immigrants, it is important to focus on the measurement quality, which is becoming increasingly complex in the perspective of international research. It is...
