Němečková, Hana ; Souček, Jiří (advisor) ; Diviák, Tomáš (referee)
This master's diploma thesis focuses on the dissemination of information in the context of the Czech community of so-called foodies (people who like good food and are constantly looking for new experiences in this field). The theoretical part outlines the development of online communities environments, from web forums to social media. It also examines the possibility of applying Katz and Lazarsfeld's model of the two-step flow of communication in the online environment. We also explain the features of online food communication and present widespread social media foodie platforms, including the Czech app Scuk. The research part of the thesis uses the social network analysis method to identify opinion leaders of this online community in the environment of Twitter, Instagram and Scuk and examines how the information spread and the form of this community changes with regards to the particular online environment in question. The thesis also includes qualitative research on the impact of the online information spread on the offline environment - more specifically, on sales, visit rate and reputation of selected Prague restaurants.

Webs of crime: Corruption in the perspective of social network analysis
Diviák, Tomáš ; Podaná, Zuzana (advisor) ; Buriánek, Jiří (referee)
In this thesis, I attempt to apply the network perspective to the study of corruption. First, I deal with current state of theory and research on corruption, which I find to be ignoring relations and interactions among offenders themselves. Then I review literature in the field of covert and criminal networks. The theoretical part of this thesis ends with brief descriptions of two major cases of political corruption in the Czech Republic - so called Nagy case and Rath case. In the methodological part, I introduce basic concepts of social network analysis as well as methods for positional analysis, especially the blockmodelling. In my research, I deal with exploratory analysis of both the aforementioned networks. Using proxy data, I analyse cohesion, centralization, centrality measures and cliques in these networks. Then I use conventional blockmodeling to search for roles and positions within these networks. My results suggest that both networks are dense and centralized with overlapping cliques contrary to other covert networks possibly accounting for their eventual disruption and failure. Positional analysis using varius methods such as CONCOR or different types of cluster analysis reveals a structure resembling the core-periphery model, which is supported by measuring coreness and finding a good...

Skála, Vít ; Potůček, Martin (advisor) ; Majerová, Věra (referee) ; Kupčák, Václav (referee)
The issue of rural areas in the Czech Republic concerns about 5,800 municipalities, what is 93 % of all municipalities in the CR. These municipalities cover more than three-quarters of the CR territory where live over 3 million inhabitants, more than one third of the total population of the CR. Although there is consensus that the countryside faces a lot of problems which affect the lives of many people on a large territory, the adequate attention to this topic is still not given by official authorities. This confirms the facts that the CR has not adopted a clear definition of rural areas yet and the rural policy is not a priority of programs of political parties. But the urgency of solving problems in recent years stepped up. Quantity of scientific teams that focus on countryside problems increased. They are defined different typologies of rural areas, are seeking methods for dissolve disparities among different areas, there are efforts to measure the development potential of municipalities.
