The diploma thesis deals with the problematic use of the internet and tries to find out whether there is a connection between excessive use of the internet and active sports. It tries to clarify whether and how much active sports reduce the risk of internet addiction with a focus on university students in the Czech Republic. The work consists of theoretical and empirical part. The theoretical part deals with the description of the background and describes the concept of addiction with a primary focus on the pathological use of addictive substances. It also discusses the area of behavioral addictions, in which it focuses on the internet addiction. This section briefly describes the situation in the Czech Republic. In the empirical part of the work, based on the evaluated questionnaires, a research sample is characterized, the result of the internet addiction test is given and the frequency of sports for the given research group is described. The final chapter is devoted to the evaluation of the whole work and research. Based on the facts found in the questionnaire, the mutual influence of active sports and the level of internet use on the examined sample was not confirmed.

This research study looks at digital academic space, which is defined here as web-based digitally mediated artifacts produced by universities and their members. Open source software projects and the Open Access movement play large roles within digital academic space, not only because of their strong historical academic roots, but also because these projects are growing in prevalence in many universities. Framed by theories from the field of higher education and media studies, this research study is an analysis of the dynamics and effects of one open source software project that produces Open Access electronic journals. The software system, called the Open Journal Systems (OJS), originally developed by an education professor from a Canadian university, has been adopted by thousands of universities world- wide to publish electronic peer reviewed academic journals. OJS users distributed at universities throughout the world have contributed software code back to the system, by for example, creating translation modules enabling users to publish journals in a range of languages thus adding an interesting global dimension to the project. Based on interviews with the OJS software developers, administrators, and users, as well as a range of material culled from online, this situational analysis of the OJS sketches out the conditions, dynamics, discourses and professional identities that form the basis of an emerging phenomenon within universities that is named here the digitally mediated open research project (DMORP
