The effect of DGE on the attainability of mathematical reasoning for geometry problems among mathematics teacher education students.
BLAŽEK, Jiří
Dynamic Geometry Environment (DGE) programs appeared in the early 1980s, but they did not begin to be used in education until the beginning of the new millennium. Today, they are widely used in teaching of mathematics. DGE class programs allow to mediate the abstract world of Euclidean geometry to students due to their features such as precision of construction, illustrativeness and the possibility to change the construction dynamically. It is generally accepted that appropriate implementation of DGE software in teaching improves its quality. A related question is what is the benefit of this software if a student uses it in the process of finding a solution to a solution to a mathematical problem. This question represents the general research problem of this thesis. The objects of the research were prospective teachers of mathematics at the Faculty of Education. The following findings were found in the research: 1) The software significantly facilitates the discovery of relevant hypotheses, even those for which their relationship to the solution of a problem is not evident from the assignment of the problem. 2) The software significantly helps in the development of logical justification. (Yet, a significant number of students in the research were unable to complete the proof even with the maximum help the software could provide.) 3) Finding relevant hypotheses using the software tools depends in most cases on students' ability to apply formal mathematical knowledge and to think logically. Facts that can be discovered with software tools by chance, without specific student intent, are likely strongly limited. Research has also dealt with the question of why some students are unable to complete a proof even with the help of software. The thesis contains seven chapters and an appendix. In the first three chapters, the research topic of the thesis is generally described. In chapter four, the research questions are formulated. In the following chapter, a model is presented to categorize the actions of the problem solver in the DGE with respect to the goal he/she pursues. Chapter six presents the research methodology, the data obtained and their interpretation. The results are summarized in the final chapter. The appendix contains two challenging geometric problems author has worked on during his studies and in whose solutions the DGE software played a crucial role.

Role of the US Foreign Policy Advisers
Blažek, Jiří ; Klepárník, Vít (advisor) ; Koubek, Jiří (referee)
This thesis focuses on the role of the advisors in the US foreign policy, especially in the decision-making process, which constitutes a part of presidential system in the United States of America. The methodology of the conceptual part is based on individual typologies of presidential control of the US administrations. The thesis also describes evolution of this discipline, which in the USA is studied in the field of Foreign Policy Analysis. The conceptual scheme of the presidential control is based on the models by Johnson, George and Mitchell. The theoretical approach to the roles of advisors is patterned on the models of Mulcahy, Crabb and Hönig. The thesis combines these theoretical bases to describe and explain the evolution of presidential control typologies. Some problematic particularities of the Mitchell typology are also reviewed in this part. The next part based on the theoretical models analyses empirical reality. The analytical part constitutes of two case studies, which describe the role of the Assistant to the President for National Security Affairs in the key deliberations of the presidential administrations of William J. Clinton (reaction to the conflict in Bosnia) and George W. Bush (preparation of the invasion in Iraq). The aim of this thesis is to applicate the typologies of...

Forming of developmental axes and regions in the Czech Republic
Lauermannová, Anna ; Blažek, Jiří (advisor) ; Müller, Jan (referee)
The aim of this study is to answer the question if it is possible in first decennium of 21st century to identify development axes or poles in Czech republic. In my research I focused on local level (NUTS V), because in many previous studies it is said, that the proces of spatial differentiation is in these days shifting from higher hiearchical levels to local level. I used the method of spatial autocorrelation because it helps to identify clusters of municipalities with high level of development potential (hot spots) or low level of development potential (cold spots) The development poles are defined as cluster of municipalities with high development potential. The main hypothesis is that the development axe between Pilsen - Prague - Liberec is deepening and that there will be discernible new development axe connecting Prague with Hradec Králové and Pardubice. This study also gives an overwiev of the most important theoretical concepts concerning development poles and axes. I also describe the aplication of these concepts in Czech republic with regard to acceptance of Territorial Agenda of the European Union .

Evaluation of ESF funded interventions aimed at persons endangered by exclusion from the labour market
Vostradovská, Barbora ; Blažek, Jiří (advisor) ; Jungwiertová, Lucie (referee)
This thesis deals with the efficiency of the measures, which are implemented within the projects supported by the European Social Fund and are aimed at the endangered groups of parents (mostly women) on the labour market. The theoretical part introduces the concept of labour market segmentation, theory of human and social capital and finally outlines labour market policies within the framework of the EU and the Czech Republic. Empirical research uses techniques of interviews and a questionnaire in order to evaluate the implementation of the measures and targeting of the funds towards the needs of this specific group of women which is under a long term threat on the labour market. The contribution of this thesis is primarily in a detailed study on the efficiency of the system of subsidies in one part of the support from the ESF from the perspective of non-profit organizations. Key words: Labour market, European Social Fund, evaluation, non-profit organizations, Prague

Global Production Networks in Czechia in the Case Study of Aircraft Industry
Housková, Štěpánka ; Blažek, Jiří (advisor) ; Csank, Pavel (referee)
Global production networks in Czechia in the case study of aircraft industry This thesis is dedicated to aircraft industry in the Czechia. It uses a relatively new concept of global production networks (GPN), which examines functionally integrated but geographically dispersed production networks. The aim of this work is to show how are the Czech companies involved in the global division of labor. Almost a quarter of manufacturers in the aircraft industry is able to participate in global production of aircraft, although at lower levels of the supply chain. In addition to this production, there is production of small and ultra-light aircrafts, which achieves international reputation. In this manufacturing sector there are companies producing basic components and also throughout the aircraft. The biggest influence on, what tier companies are, is the age of company and in the case of companies involved in the production networks of large aircrafts also foreign ownership and size. In case of companies producing small aircraft it is tradition and experience than the size and ownership. The capacities of research depend on the position of company in the firm hierarchy. Most companies are suppliers of several firms and they are also involved in the production in other sectors. Very important institutional support...

A Comparison of Apocalyptic and Rationalistic Tendencies in Mediaeval Judaism
Blažek, Jiří ; Nosek, Bedřich (advisor) ; Biernot, David (referee)
The theme of this work is Jewish messianism and its apocalyptic and rationalistic tendencies in Middle Ages. The thesis is opened by short introduction to phenomenon of messianism and its historical development throughout centuries, with a description of the biblical word Mashiah: how the word, which literally means "anointed", became synonym to words like "savior" or "redeemer". This part of the work reveals the necessary historical background - events that led to two great Jewish rebellions, destruction of ancient Israel and codification of Talmud face to face the growth of Christianity. All these events formed the Jewish messianism in following centuries.

Creative Industries in the Old Industrial Region
Sochorová, Martina ; Blažek, Jiří (advisor) ; Rumpel, Petr (referee)
Creative industries are considered as a new oportunity and a tool of economical and social growth in developed countries, because they represent a "new" source of wealth and prosperity. Creative economy is not based any more on traditional manufacturing industry and that is why are these now in the interest forefront of experts and executives. In the frame of the city and region development are creative industries seen as a new competitive advantage and they play role in innovative process and competitiveness of firms, towns or regions. Research section of my thesis is focused on old industrial regions, exactely on comparative analysis of Ústecký and Moravian-Silesian region. Emphasis is put on a spatial organization of creative industries and on their further characteristics, reviewed by different indicators. Concerning the town Ústí nad Labem, my thesis is focused on advertising industry, which has been considered as a new dynamic industry since 1989.
