Semantic technologies are about to play a crucial role in this integrative process. However, cross-company data exchange requires mechanisms to enable fine-grained access control definition and enforcement, preventing unauthorized leakage of confidential data across company borders. Currently available semantic repositories are not sufficiently equipped to satisfy this important requirement. This paper presents an infrastructure for controlled sharing of semantic data between cooperating business partners. First, we motivate the need for access control in semantic data federations by a case study in the industrial service sector. Furthermore, we present an architecture for controlling access to semantic repositories that is based on our newly developed SemForce security service. Finally, we show the practical feasibility of this architecture by an implementation and several performance experiments.}, language = {en} } @article{WinklerGoebelBidaultetal.2012, author = {Winkler, Till J. and Goebel, Christoph and Bidault, Francis and G{\"u}nther, Oliver}, title = {Information technology and business practieses in Germany}, series = {The UCLA Anderson Business and Information Technologies (BIT) Project}, journal = {The UCLA Anderson Business and Information Technologies (BIT) Project}, publisher = {world scientific}, address = {Singapore}, doi = {10.1142/9789814390880_0005}, pages = {81 -- 114}, year = {2012}, language = {en} } @article{GuentherBrechtEckhardtetal.2012, author = {G{\"u}nther, Oliver and Brecht, Franziska and Eckhardt, Andreas and Berger, Christian}, title = {Corporate career presences on social network sites: an analysis of hedonic and utilitarian value}, series = {CHI '12 Proceedings of the SIGCHI Conference on Human Factors in Computing Systems}, journal = {CHI '12 Proceedings of the SIGCHI Conference on Human Factors in Computing Systems}, publisher = {ACM}, address = {Texas}, isbn = {978-1-4503-1015-4}, doi = {10.1145/2207676.2208408}, pages = {2441 -- 2450}, year = {2012}, abstract = {Due to the shortage of skilled workforce and the increasing usage of social network sites, companies increasingly apply social network sites to attract potential applicants. This paper explores how corporate career presences on network sites should be realized in order to attract potential applicants. Therefore, we tested the impact of seven individual characteristics (namely Appointments, Daily Working Routine, Jobs, Corporate News, Entertainment, Media Format, and Features) of these corporate career presences that we extracted by a comprehensive pre-study on users' perceived hedonic and utilitarian value of these presences on social network sites. Based on an online survey with 470 participants, the results reveal a highly significant impact of five characteristics that corporate career presences provide both a hedonic as well as a utilitarian value to the user}, language = {en} } @article{Guenther2014, author = {G{\"u}nther, Oliver}, title = {Big Data: What is it?

As a result, stimulating user communication and self-disclosure is vital for the sustainability of SNSs. However, considering that the SNS users are increasingly culturally diverse, motivating this audience to self-disclose requires understanding of their cultural intricacies. Yet existing research offers only limited insights into the role of culture behind the motivation of SNS users to self-disclose. Building on the privacy calculus framework, this study explores the role of two cultural dimensions - individualism and uncertainty avoidance - in self-disclosure decisions of SNS users. Survey responses of US and German Facebook members are used as the basis for our analysis. Structural equation modeling and multi-group analysis results reveal the distinct role of culture in the cognitive patterns of SNS users. The authors find that trusting beliefs play a key role in the self-disclosure decisions of users from individualistic cultures. At the same time, uncertainty avoidance determines the impact of privacy concerns. This paper contributes to the theory by rejecting the universal nature of privacy calculus processes. The findings provide for an array of managerial implications for SNS providers as they strive to encourage content creation and sharing by their heterogeneous members.}, language = {en} } @misc{Guenther2015, author = {G{\"u}nther, Oliver}, title = {Grußwort des Pr{\"a}sidenten der Universit{\"a}t Potsdam}, series = {20 Jahre MenschenRechtsZentrum}, journal = {20 Jahre MenschenRechtsZentrum}, editor = {Gunnarsson, Logi and Zimmermann, Andreas}, publisher = {BWV Berliner Wissenschafts-Verlag}, address = {Berlin}, pages = {9 -- 11}, year = {2015}, language = {de} } @incollection{Guenther2015, author = {G{\"u}nther, Oliver}, title = {Zum Geleit}, series = {Raum und Zahl im Fokus der Wissenschaften : eine multidisziplin{\"a}re Vorlesungsreihe}, booktitle = {Raum und Zahl im Fokus der Wissenschaften : eine multidisziplin{\"a}re Vorlesungsreihe}, publisher = {Trafo}, address = {Berlin}, isbn = {978-3-86464-082-7}, pages = {7 -- 8}, year = {2015}, language = {de} }
