Serverless single page application in JavaScript
Zikmund, Marian ; Pecinovský, Rudolf (advisor) ; Suchan, Vladimír (referee)
The goal of this thesis is to design and develop a framework for building modern single- page application in the JavaScript programming language and describe this approach to development. The work also contains the documentation for a more comfortable use and customization. The content is divided into eight chapters. The introduction is followed by the retrieval of information resources, including the specifics of the JavaScript programming language and explanation of the formation of single-page application. The description of the basic principles of their functioning, motivation and justification, when and why this approach is appropriate is also included. The work is primarily focused on the issue of single-page application, for which the use of the JavaScript programming language is crucial. For this reason, this work provides a whole chapter about this programming language, also including a description of its history and role in the context of others. Below are the common characteristics of single-page applications frameworks, built on top of the library ReactJS, whose formation is engaged in the following chapter. The developed framework also contains the user guide. The practical outcome of this work is an open source framework for creating serverless single-page applications, which is due to its architecture and documentation appropriately adaptable.

Information systems security penetration testing
Klíma, Tomáš ; Doucek, Petr (advisor) ; Čermák, Igor (referee) ; Čapek, Jan (referee) ; Štubňa, Ivan (referee)
The aim of this dissertation thesis is to develop new methodology of information systems penetration testing based on analysis of current methodologies and the role of penetration tests in context of IS/IT governance. Integral part of this aim is evaluation of the methodology. The first part of the thesis is devoted to the presentation of history and current state of research in selected area, definiton of basic terms and introduction of role of the penetration tests. This part is followed by the review of relevant sources and comparative study of current methodologies with a goal to identify their weaknesses. Results from this study are further used as a basis for new methodology development. Classification of IS penetration tests types and testing scenarios are also included. The second part includes design of new methodology, at first its history, structure and principles are presented, then its framework is decribed in high level of detail. In the third part the reader can find (theoretical and practical) validation. The biggest scientific contribution is the methodology itself focused on managment of penetration tests (which is the area currently not sufficiently descibed). Secondary contribution is the extensive review and the comparative analysis of current methodologies. Contribution to the economic and technical (practical) application we can mainly see in the development of new methodology which enables companies to improve management of penetration tests (especially planning, operational management and implementation of countermeasures).

Speculation on oil markets and its impact on commodity's price
Melcher, Ota ; Taušer, Josef (advisor) ; Baláž, Peter (referee) ; Müller, Štěpán (referee)
This study aims to analyse the precrisis period on the oil markets with a primary objective of assessing the role of speculation in the commodity's price development and its volatility. First it depicts the rapidly increasing speculative activity on the futures market together with the parallel oil price surge. The speculation is initially proxied by non-commercial traders' positions and subsequently quantified by Working's T-index. The paper then uses speculative traders' positions and both spot and futures prices to test for Granger causality within the framework of VAR models. For the sake of consistency it also evaluates causal links between speculation and inventories level. Further the study investigates the speculation impact on volatility of oil prices by employing various approaches in volatility quantification including GARCH models. Contrary to expectations we find that the speculatio's impact on both prices and their volatility is rather insignificant. In the last chapter we therefore seek for an explanation of the oil price developments by examining the market fundamentals. The interaction of supply and demand finally gives substantial evidence for understanding the price developments in the precrisis period.

Determinants of Industrialization in sub-Saharan Africa and Possibilities for their Development
Sejkora, Jiří ; Jiránková, Martina (advisor) ; Šaroch, Stanislav (referee) ; Fárek, Jiří (referee) ; Adamcová, Lenka (referee)
Sub-Saharan economies need structural changes that would enhance their productivity, increase economic growth and development. In this regard, industrialization plays a key role. Using regression analysis, the aim of this dissertation thesis is to identify main factors (determinants) of industrialization in sub-Saharan Africa. The results indicate that infrastructure and economy size (measured by population size) represent main determinants of industrialization in the region. The thesis also deals with possibilities for development of those determinants. Case study of infrastructure development in Mauritius emphasizes privatization, cooperation with external subjects etc. Negative consequences of small economy size can be overcome by preferential trade agreements (under certain circumstances), as shown by analysis of the three smallest economies in the region.

Role of UNHCR in case of asylum seekers, refugees and stateless persons – the case study of Turkey
Unzeitigová, Klára ; Novotná, Markéta (advisor) ; Kuchařová, Alžběta (referee)
Inspired by the Kratochvíl, Cibulková and Beník´s model of actorness, the thesis explores the framing power of UNHCR. The critical discourse analysis introduced by Norman Fairclough is applied in order to analyze the textual, contextual and sociocultural dimension of the UNHCR framing power. The case of Turkey was chosen for this study due to the current situation and the fact that Turkey is one of the biggest hosting country in the refugees´ crisis. Through the critical discourse analysis, the thesis explores whether UNHCR is considered as a framing actor in the case of asylum seekers, refugees and stateless people in Turkey. The analysis shows that UNHCR is globally respected and takes important part in the issue. However, not all of the international organizations refer to UNHCR as the lawmaker and the initiator of debates in the issues mentioned above.

International involvement in the peacebuilding process on Sri Lanka
Mojžíš, Michal ; Havlová, Radka (advisor) ; Burešová, Jana (referee)
The final months of Sri Lankan civil war, the 26 year military campaign between the Government of Sri Lanka and the insurgent separatist organization Liberation Tigers of Tamil Eelam, are marked by allegations of war crimes committed by both parties of the conflict, including attacks on civilians, summary executions of prisoners, enforced disappearances, restrictions on humanitarian assistance and recruitment of children. Since the attempts to put the Sri Lankan issue on the agenda of the United Nations Security Council failed on the unwillingness of China and Russia, the UN bodies in Geneva have taken a leading role in promoting the peacebuilding process on the island. The thesis aims to analyse the impact of the Geneva-based human rights bodies, in particular of the United Nations Human Rights Council, on the process of reconciliation in Sri Lanka, for which is crucial that the alleged violations of human rights in the last months of the civil war would be properly investigated and that the perpetrators would be held accountable. In order to put the activity of the UN Human Rights Council into broader context, the paper will examine the political development in Sri Lanka since the end of the civil war in 2009 as well as the failed efforts of Sri Lankan governments to launch the process of reconciliation.
