Knowledge in the information society
Řezníček, Václav ; Rosický, Antonín (advisor) ; Mildeová, Stanislava (referee)
In spite of the fact that contemporary society is called information or knowledge society, the meaning of terms information and knowledge is often out of our attention. The author seeks, bearing in mind the seriousness of discussed topics in the text, to present a systemic view with emphasis on the interrelationship between ideas and phenomena, based on a thorough definition of the theoretical foundations. The main aim of this work is to (from several different perspectives) point out selected important consequences of knowledge "objectification". It turns out that theme of education plays a major role in response to the question which modern society faces in the context of informatization.

New Media and Society
Fedorová, Markéta ; Rosický, Antonín (advisor) ; Říhová, Zora (referee)
The thesis deals with the phenomenon of new media and its influence on the society. The work especially applies itself to the impact of new media on human conduct and human knowledge. The first part (Chapters: introduction and theoretical bases) of the thesis introduces the dilemma of new media and the society; it deals with a theoretical media frame, communication, knowledge and some selected implications of informatization. The third chapter (Media evolution) tries to map media evolution from the emergence of language until contemporary electronic media with regard to consumer's limitations, society and media itself. The fourth chapter (Impact of new media on human knowledge and human conduct) deals with, from two perspectives, some current topics as the media influence on society. The first view delivers an insight on the relationship of new media and knowledge. It refers to information abundance to the detriment of information quality, the tendency of access acceleration to information and working with information. This chapter in particular cases shows how information can become an effective tool for manipulation of power, political and economic interests. It also indicates risks of wrong human decision making due to misinformation. The second view suggests changes in human behaviour in cyberspace; it indicates what are signs of confluence of "front stage" and "back stage" behaviour. The fifth chapter (Empirical research), with respect to previous parts of this work, defines hypothesis of the new media influence on the knowledge and human conduct; it attempts to prove their validation in this research. The sixth chapter (How to use new media) suggests a way which should be followed by the society providing that education of an individual who stands up to the information and media society shall be the aim of the society. The last chapter (Conclusion) summarizes the basic ideas, provides for possible solutions and outlines a trend which should be, in relation to new media, followed by the society.
