Three of Impatiens species are widespread in the Czech republic, one is native, two of them invasive. Because all species occur in relatively similar habitats, the question is, whether the invasive species can negatively affect the native species, or even the original can can be displaced. The aim of the thesis was: (i) to compare habitat requirments of the Impatiens species, (ii) to determine if the coexistence of species is possible, (iii) to assess the impact of invasive species to the original species. The investigation was carried out using two sets of permanent plots in 5 localities. In the first set with a total of 84 plots (combinations of occurrence of the three species) site characteristics as tree cover, soil humidity, slope and bare land cover were directly measured and nutrient, light, humidity and soil reaction characteristic assessed using Ellenberg indicator values. The second set contained a total of 45 plots with one of the native-invasive congener pair being removed and the intact controls. Number, cover and height of the plants were assesed. The key enviromental factors determining distribution of the species were soil moisture for I. noli-tangere and I. parviflora, and tree cover for I. glandulifera and I. parviflora. Ellenberg indicator values had poor explanation value;...

Lusatia in the plans of building the new Czechoslovakia. Great expectations and early disillusionment of the Czech Slavists. During the Great War, especially in the last year of the war, a number of representatives of Czech political and cultural life reflected upon an idea of a renewal of the Czech state in a historical borders of the former Czech crown lands. The independence of Czechoslovakia was proclaimed on October 28, 1918, by the Czechoslovak National Council in Prague. Only several years before, an independent Czechoslovakia had been a dream of a small number of intellectuals and politicians. The transformation of the dream into reality was a formidable task. While the creation of Czechoslovakia was based on certain historical precedents, it was, nevertheless, a new country carved out of disparate parts of the old Hapsburg Empire. This study deals with the matter of how Czechoslovak scientists, first of all slavists, intervened in the forming of Czechoslovak political programme. Slavists' role in the communal life of Czechoslovakia has been transforming due to changes that took place in both local and international politics. For a long time before they had no chance to participate at official state politics as there was not a sympathetic for Slavonic cooperation on an international level...

V ANGLICKÉM JAZYCE Private-law consequences of a breach of competition law and their enforcement in the Czech Republic The private-law consequences of a breach of competition law, Articles 101 and 102 of the Treaty on the Functioning of the EU and Sections 3 and 11 of the Czech Competition Act, may affect many entities, irrespective of whether they are competitors or consumers. Recently, emphasis has been placed on private enforcement of competition law that is intended to serve as an important complement to public law enforcement. The first part of the dissertation defines basic concepts and principles of competition law including "public rules on restriction of competition". The history of the enforcement of competition law in the Czech Republic and the dynamic development in this area at the EU level are outlined in the second part. The third crucial part of this work deals with the right to damages caused by a breach of competition law in the Czech Republic. In 2014, the EU adopted Directive 2014/104 on certain rules in damages actions with the view, inter alia, to increase the effectiveness of private enforcement of competition rules by civil courts of EU Member States. On August 18, 2017, new Act No. 262/2017 Coll. which implements the Directive into Czech law was adopted. The dissertation...

This dissertation deals with how the subject matter of performance under a contract for work is defined and issues related to formulating the rights and obligations ensuing therefrom. At the same time, it seeks common legal sources existing across national laws which provide definitions thereof. It attempts to find a common definition of contracts for work and how they differ from other similar contracts. It further defines some common basic features and problems related to contracts for work which apply in international trade or in cases where parties decide to formulate their contract by reference to international contract conditions. In that context, it primarily refers to construction contracts as the most common type of contract for work in international trade. At the same time, it focuses on the possible consequences of a breach of contract and emphasizes some parties' claims ensuing therefrom. Moreover, this work examines the definition of work defects and conditions for asserting claims as a specific topic, which relates to the definition of the subject matter of a contract for work and its basic features. Key words: contract for work, construction work, contractor, employer, international trade, sources for determining obligations, international contract conditions, subject matter of...
