Engl. transl.: Identity, Orientation and Lifeworld. A multidimensional perspective on situational negotiation of privacy within the social web.

Privacy is closely related to identity and communication. This volume explores this connection offline in everyday life and especially on social media. The author provides a multidimensional theory of courses of action that can be taken, and illustrates its benefits by combining three empirical sub-studies. It reveals different concepts of privacy and certain courses of action related to them in terms of self-presentation and communication on social networking sites. Additionally, it explores the motivations and attitudes of non-social media users, focusing in particular on the relevance and usage of photographs both offline and online. To gain a deeper insight and to illustrate the benefits of the multilevel perspective pursued here, a study was conducted which combines data from a quantitative questionnaire, qualitative interviews, the sorting and evaluating of photographs, and a content analysis of social networking sites.

Sascha Trültzsch-Wijnen deals with the online use of adolescents and young adults, with a special focus on the social web. The great added value of the work is the diverse and profound theoretical part of the study. Based on this, the author designs a complementary, triangulative research design that combines a quantitative online survey with qualitative guided interviews and, as an additional element, the evaluation and attribution of photos by the respondents. A content analysis serves as a further empirical approach. In this way, Sascha Trültzsch-Wijnen succeeds not only in exploring motives for use, but also the hitherto often neglected aspect of non-use.
