The presented thesis deals with the temporal and spatial changes in activity of the European beaver (Castor fiber L.) during different seasons. Basic dataset was obtained by continuous telemetric monitoring of selected individuals in years 2008 and 2009 in two different geographical areas, namely in the Bohemian forest and in southern Moravia. The scope of the thesis was to record, evaluate and interpret the behavior of European beaver during the year. I focused myself especially on the beginning and end of activity in relation to incidence of sunrise and sunset, duration of stay in the field, changes in the size of actively-used area and time-duration and length of the movement. In cases where there were more active individuals monitored within the studied area, I also watched for their mutual interaction. In statistical analysis of gained data I also took into account the sex and age of the individuals. Beaver's behavior varies during the year. They are most active in spring and autumn, while in winter their activity decreases significantly. This observation is valid not only for the time duration and length of movement trajectories, but also for the size of actively-used area. The beginning of activity is strongly correlated with the sunset, while the end does not show any correlation with...

The area of individual reclamation of receivables in the form of court-ordered distraints has undergone significant changes since the year 2000. The initial practice, when the claims used to be enforced directly by judicial officers, proved to be largely ineffective and with difficult to apply. The Ministry of Justice has responded by adopting an amendment to the Act (Act no. 120/2001 Coll., on bailiffs and executor activities), which introduced the independent bailiff offices. Then, the law itself understood the bailiff authorities as a separate entrepreneurs. Currently, in the Czech Republic, there can be seen the distribution of the market with distraints according to the Pareto rule. Approximately 20% of bailiff offices manage over 80% of distraints. It is obvious that this is an unsatisfactory condition for the majority of bailiff offices. In response to this fact, the Czech Chamber of Bailiff offices calls for the introduction of territoriality, which would eliminate by law the market environment from the market with distraints and every single bailiff office would have a stable allocation of distraint proceedings. The analysis carried out clearly shows that there are significant differences between bailiff offices in terms of speed and in success of the debt recovery. The actual demand for the introduction of territoriality would not merely be a reallocation of the market with distraints. Putting it into a practice would greatly influence the transactional costs of business and non-business entities in the Czech economy. The thesis comprehensively describes the issue of territoriality and quantifies how much the debt collection will decrease in case of its introduction. In the conclusion, an alternative draft is formulated, which might, according to the author, allow effective regulation and supervision of the activities of bailiffs' offices without compromising the inherent efficiency of the reclamation of receivables in terms of market environment.

Panelstories: Ethnography of Space (Re)production at Černý Most Modernist Housing Estate. Mgr. Michal Lehečka Abstract: The dissertation focuses on spatial environment of socialist modernist housing estates. Based on data collected during a 10year long fieldwork in multiple modernist housing locations, it explores dominant ways of spatial (re)production of Černý Most housing estate in Prague. Thanks to its ownership and ethnic structure Černý Most represents an ideal fieldwork site where both long term and contemporary phenomena resulting from the post-socialist transformation can be detected, described and analysed. After 1989, former socialist modernist cities have undergone a plethora of political, economical and social changes and disruptions. These changes continuously uncover an ongoing interaction between the initial egalitarian and collectivist heritage of the housing estate as well as its ambiguous and fragmented property structure. Spaces of the estates are continuously (re)produced through various manifestations of actors' territorial claims. The spatial changeability is best described by Henri Lefebvre's notion of socio-material (re)production of space and his widely used concept of spatial triad (Lefebvre 1991). Transformation of housing estates is therefore (re)produced through (in)visible...

This thesis deals with the institute of private distrainor in terms of its position in the Czech legal order. It outlines the history of enforcement process and discusses the powers of the private distrainors in accordance with the relevant laws. The theoretical part describes the functioning of various mechanisms in the enforcement proceedings, with an emphasis on the most common types of acts. In the analytical part it focuses on the changes made in 2015 and further analyzes prepared or discussed changes in enforcement proceedings. Specific problems closely connected with the institute of private bailiff are described and at the same time there are suggested possible solutions to these problems.

The new fact that the environment is becoming the main factor of geopolitical transformations in the Arctic region has been triggered mainly by climate change. In the North, this recent aspect of geopolitics, in correlation with the environment, leads sometimes to tensions between countries, but also to a need for cooperation. The question brought by such conditions is, to which extent will this climate change provoke cooperation or conflicts between the Arctic states. The purpose of addressing the problem is to understand what kind of challenges would be facing the international relations between circumpolar countries and how the environment is playing a geopolitical role in them. The objective of the main research question is to assess the importance of climate change over the geopolitics of the Arctic through several spheres of geopolitics: environment and bio-diversity, economic activity of the region, sovereignty and territoriality, security of the circumpolar states, and international and diplomatic relations. The trans-border and transnational nature of environmental issues is another important factor, since nature does not respect human-made boundaries and an environmental concern, such as climate change and its aftermaths, cannot be exclusive to a state along the lines of its borders.

The number of border barriers has increased rapidly in the last decades. These barriers appeared between the wealthy and the poor, between the stable and those ridden by civil wars, between traditional military rivals and even between partners in the integration process. This suggests that a complex theory is necessary to explain the phenomenon of border barrier building. The presented work aims to provide an answer to the question of why states build border barriers by the use of Schmitt's theory of state based on nomos, sovereignty and political unity in interaction with globalization. This theory served as a framework for establishing the independent variables, namely challenges to land-appropriation, challenges to sovereignty from military threat, challenges to sovereignty from cross-border ethnic group, challenges to political unity from irregular mass migration and finally challenges to political unity from terrorism. These were then tested using regression analysis with number of border barriers constructed by a state serving as a dependent variable. The results suggest that states that often face challenges to land-appropriation, to sovereignty coming from politicised cross-border ethnic groups and to political unity from irregular mass migration build more border barriers than those that...
