The main aim of this diploma thesis was to identify the international sales contract with a focus on the definition of the international sales contract, the sources of law which govern the international sales contract and the United Nations Convention on Contracts for the International Sale of Goods, with a closer focus on the formation of the contract and rights and rights and obligations of the buyer and the seller under the Vienna convention and the relevant case law for these issues, as well as the gaps in the Vienna convention. The methods used to develop this diploma thesis are analysis, description and synthesis. Analysis is used to the greatest extent in the third chapter, description is used especially within the first and second chapter and the synthesis is used within the recapitulations at the end of each chapter and within the summary. Within the first chapter I focused on the definition of the international sales contract and its distinction from the classical sales contract. The second chapter deals with the sources of law, which govern the international sales contract. In this chapter, I focus on the direct regulation, conflict of law rules, imperative legal norms, international treaties, European law, choice of law, international business practices, national law, lex mercatoria,...

The aim of this diploma thesis is to analyze various legal aspects related to mergers of public limited liability companies. The thesis begins with a summary of relevant legislation from Czech and European jurisdiction regulating domestic and cross-border mergers. It continues with the procedure of merger and the overview of necessary documentation and requirements. Broad part of the work is related to the impact on diverse areas, such as the impact on shareholders, employees or bookkeeping. The system of merger control is defined within the scope of the chapter dealing with effects on competition law. The legal aspects are illustrated on a practical case in the end of the thesis.

Pragmatically motivated communicative action loop (CAL) is proposed for modeling business transactions and designing database transactions. Using parameters of the communicative action loops, activity model can be adapted to particular objective area. Selected parameters are utilizable in formation of database transactions that are oriented in modification of states of objects of activity. Performed database transactions are registered to query register in order to make a database rollback when business transactions are canceled. Database transactions are synchronized between two replicated databases.

The aim of this thesis is to provide detailed analysis of selected legal aspects with practical importance of the assignment of business receivables. Particular topics are focused on problematic legal features of cession, that have so far not been sufficiently elaborated in expert literature, mainly with regards to the impacts of the recent transformation of the Czech civil law. The issues are approached as comparison between the previous law and the current law, which is in force since 1st January 2014, alongside taking account of solutions for chosen issues under German law.

A Contabilidade, na qualidade de Ciência voltada à administração e a economia, envolve, a um tempo, um valor específico e uma prática abrangente, na medida em que tem por função orientar, controlar e registrar eventos econômicos proporcionando informações para a tomada de decisões. Esse conceito exige, portanto, dos seus profissionais, uma visão sistêmica, holística e interdisciplinar, que lhes possibilite um desempenho de qualidade. No entanto, as estratégias de ensino utilizadas, ainda hoje, têm priorizando os aspectos operacionais da Contabilidade, em detrimento da sua capacidade informativa, que implica necessariamente juízo de valor. Visando contribuir para dotar o ensino da Contabilidade Geral em nível de 3º grau de um instrumento de aproximação entre a teoria e a prática que reflita melhor a realidade das empresas e suas necessidades das informações contábeis para a tomada de decisões, esta pesquisa objetiva a apresentação de um simulador de transações, em forma de jogo, aplicado ao ensino da Contabilidade Geral. Por meio da pesquisa-ação, desenvolve-se a modelagem de um simulador de transações, em forma de jogo, desdobrando analiticamente a tomada de decisão num processo de planejamento, execução e controle, valendo-se para isso da teoria dos jogos, levando o aprendiz a tomar decisões e fazer julgamento de valor. Ao elaborarmos um simulador de transações e aplicá-lo em sala de aula, a nossa contribuição reside não na estratégia em si, mas, antes, no processo de comunicação, motivando o aluno a participar de uma situação simulada. Importa, sobretudo, a representação, ou seja, a ficção que obriga a trabalhar não apenas tendo em vista o real, mas aquilo que tem a aparência de real, e que possibilita o interesse do jogo para o aluno. Conclui-se da pesquisa que o uso do simulador de transações, em forma de jogo, estimula e favorece o aprendizado dos conteúdos propostos pela disciplina de Contabilidade Geral, proporcionando ao aprendiz a visão abrangente desejada. / Accountancy as a Science oriented to management and economy involves at the same time an specific value and more encompassing practices based on the purpose to guide, control and record economic events providing information for decision making. This concept demands, however, a systemic, holistic and interdisciplinary view from professionals to achieve high quality performance. Nevertheless, teaching strategies used both in the past and today have prioritized the operational aspects of Accountancy to the detriment of its informative ability which involves a judgment of value. The goal of this study is to help in providing an instrument that can bring together theory and practice in the teaching of General Accounting Level 3 that better expresses business reality and the needs of accountable information for decision making. In addition to the presentation of a simulator of business transactions as a game applied to the teaching of General Accounting. This model representation of business transactions as a game will be developed by means of action-research. This game will analytically unfold the decision making during the planning, performance and control of a process using the theory of games and leading the learners to make decisions and judge values. The key factor of this representation of business transactions and its application in class will not be the strategy itself, but the communication process. It will encourage the students to participate in a simulated situation. All in all, the key aspect is the role play, or in other words, the fiction that encourages the work not only having real facts, but also with the representation of real-life situation and this will increase students interest in the game. The final conclusion of this study is that the use of a simulator of business transactions as a game encourages and favors the learning process of the subjects proposed by General Accounting, therefore providing the students with the desirable comprehensive view.
