Digitale Spaltung im Zeitalter der S?ttigung

Using Bourdieu??s Habitus-Capital theory and a representative dataset this study shows that social position influences internet use. The study is thus connected to the research about thedigital divide. A secondary analysis of the ACTA 2008 (n?=?7.623, representative of Germans between 14 and 64 years who use the internet) shows on the one hand that there are still gaps in internet usage (gender, generation, and education gap). On the other hand the results indicate acapital gap. Since the accumulation of capital in the internet is connected with education as well as economic status, there is a threat of a downward spiral: Those who have less capital (education, money) gather less internet knowledge. Since cultural capital influences a person??s social position, internet use enhances social inequality.     

Innovativer Energiespeicher Bundeswasserstraßen

The present analysis provides a contribution to the question of how a system integration of large-scale energy storages can be implemented. It is to be investigated if and how federal waterways can be used for this purpose. Initially, a baseline study was carried out in which the federal waterways are systematically assessed with regard to their suitability for/as energy storage systems. Apart from the technical and the hydro mechanical implementation of the storage process, the advantages and disadvantages of the federal waterways in comparison to conventional pump storage stations play a significant role. A presentation and classification of the potentially available canal sections provides an overview of the suitable storage systems of the federal waterways. A specifically designed storage simulation on the basis of a sample application is used, in order to determine the capacity of the canal system for energy storage. Consequently, the simulation showed the theoretical capability of the federal waterways as energy storage systems, through their ability to balance the load and temporal fluctuations of the energy input. The simulation program Matlab was used on the basis of the synthetic load and delivery profiles. Finally, based on the example of the ships lock in Uelzen and the Scharnebeck boats lift, a simulation of the possible re-equipping options will be described, technically abstracted, economically analysed and combined with renewable energy facilities within a virtual power plant. The detailed formulation of further approaches and the calculation of possible application scenarios play a central role within this analysis.     

Genetische Untersuchungen im Versicherungsbereich – Offene Fragen im Rahmen von § 18 GenDG

The paper refers to legal questions that arise in connection with the collection and use of genetic data in the context of private insurance. The content and meaning of § 18 GenDG is described. Then, § 18 GenDG is set in relation to notification requirements out of the VVG. The paper exemplarily emphasizes that, despite the codification of GenDG, specific legal problems arise. Accordingly, the paper provides solutions to overcome these problems. Particular problems refer to the role of genetic data of third parties and according relations to the family history, possibilities to communicate genetic data by the insured in case of medical indication, the ratio of predictive and diagnostic genetic testing and the range of the total limits of § 18 I 2 GenDG.
