Many critics of rational choice theory aim at unrealistic psychological assumption of this theory. To what extent is this kind of critic relevant? If we analyze the formalized scheme of choice than we will find difficult to interpret this scheme as psychological theory that develops intentional explanations. We should rather understand this theory as a theory developing causal explanations that are generated by the structure of surrounding. Intencionality in this theory is only a auxiliary tool and the explanation is made in terms of structure, not in terms of mental states. From this perspective most of the critic aim at wrong target.

This diploma work consists of two parts ? theoretical and practical. The theoretical part concerns on questions which accompany man since his childhood till the end of his life. It looks for answers for questions from different points of view. It looks at the problems from religious, scientific and historical points of view. It connects questions in the historical context. It gives ideas how to make these questions accessible for children. It uses digital photos for displaying the pictures which are further adjusted by using the computer graphics. It thinks over the texts and visual works dealing with the questions which accompany a man and with looking for answers. It focuses mainly on questions about life, the meaning of life, death, life after death, violence and the end of the world. It explains the term ? artist?s book?, it is concerned with the history of this visual media and main representatives dealing with making of artists? books. The aim of this work is to make an author?s book which would be stimulation for thinking of the questions and looking for the answers for them. This book would be created with the help of graphic techniques and on the basis of theoretical knowledge and comparing different points of view.

Migration offers a spectrum of illegal channels through which migrants enter their target countries. Marriages of convenience are one of these ways. Specifically this means marrying a foreigner who has no residence status or has a lower one than their partner they are marrying. Their partner may be the citizen of their target country or also a foreigner, however, having a higher residence status. People entering such marriages misuse the marriage institute in order to obtain a legal residence in the given country. The objective of the diploma thesis is thus illegal migration through marriages between nationals coming from third countries of the Muslim world and people living in the area of the Czech Republic. Subsequently, foreigners obtain the status of a family member, of an EU citizen, and together with that the right of a free residence and movement within the EU. The general aim of the research was to compare two categories of these foreigners who were looking for the entry into the Czech Republic based on a short-term visa. One category consisted of visa applicants who succeeded in their applications, and those whose applications were refused due to a detected circumvention of the immigration law in the form of a marriages of convenience. Both groups were compared based on chosen indicators...

Many scientific disciplines rely on the construction and use of models: biomedical sciences are no exception. This PhD thesis addresses several aspects of the practice of scientific modeling. First, I discuss the nature of modeling as such, proposing a novel, complementary account of scientific modeling which I term the experimentation-driven modeling account and which drives the construction of mechanistic models in many fields of biological and biomedical research, such as cancer immunology. Second, I scrutinize an objection to the mechanistic account of explanation according to which the account fails to accommodate the common practice of idealizing difference-making factors. I argue that this objection ultimately fails because it is riddled with a number of conceptual inconsistencies. Third, I analyze the roles of similarity judgments in some fields of cancer research which employ a variety of mouse models to learn about the disease mechanisms, arguing that by appreciating the epistemic complexities it is possible to shed new light on more general philosophical debates regarding scientific representation. Fourth, mechanisms can also be studied using more theoretical apparatus in the form of simulations. I investigate an example of an agent-based model used to model the outbreak of SARS-CoV-2...
