Despite recent interest in the role of trust in Information Systems, the potential of IS to foster trust in business relationships remains largely untapped. In order to better realize this potential, this dissertation examines three areas of IS trust research for which research is particularly limited: (1) the IT artifact as a target of trust, (2) IS-based source credibility as an antecedent of trust, and (3) the effect of anonymity on trust in online environments. The objective of this dissertation is to examine the effects of IS on trust in each of these areas. To do so, a multi-paper dissertation format is adopted in which each area examined constitutes a distinct, though complimentary, study. Together, these studies further research on how IS can enhance trust in business relationships.

The present diploma thesis maps the concepts, characteristic features and cultural-social contexts of functions of the "Do It Yourself" phenomenon. It addresses various interpretations of the phenomenon, it creates general features, and it attempts to define its position based on the experience gained from the research carried out and from the literature studied. It primarily captures the action of the phenomenon during the communist and post-communist era in the Czechoslovak and later the Czech Republic, as well as the influence of various socio-political systems on its appearance. Didactic elaboration of the topic focuses on the application of the DIY principles in teaching activity and it presents an "In & Out" artwork line integrating these ideas into the current conditions of teaching art education. The artwork part represents starting points, the process and the realization of the author's binding of the diploma thesis, which is again based on the application of DIY ideas.
