  abstract  = {"Deal of the Day" (DoD) platforms have quickly become popular by offering savings on local services, products and vacations. For merchants, these platforms represent a new marketing channel to advertise their products and services and attract new customers. DoD platform providers, however, struggle to maintaining a stable market share and profitability, because entry and switching costs are low. To sustain a competitive market position, DoD providers are looking for ways to build a loyal customer base. However, research examining the determinants of user loyalty in this novel context is scarce. To fill this gap, this study employs Grounded Theory methodology to develop a conceptual model of customer loyalty to a DoD provider. In the next step, qualitative insights are enriched and validated using quantitative data from a survey of 202 DoD users. The authors find that customer loyalty is in large part driven by monetary incentives, but can be eroded if impressions from merchant encounters are below expectations. In addition, enhancing the share of deals relevant for consumers, i.e. signal-to-noise ratio, and mitigating perceived risks of a transaction emerge as challenges. Beyond theoretical value, the results offer practical insights into how customer loyalty to a DoD provider can be promoted.},

  abstract  = {Information integration across company borders becomes increasingly important for the success of product lifecycle management in industry and complex supply chains. 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.},

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},

Belling in den Ruhestand gehalten wurden: Der Beitrag des Ministers der Justiz von Ungarn, L{\´a}szl{\´o} Tr{\´o}cs{\´a}nyi, befasst sich mit dem Thema Demokratie, Identit{\"a}t und Rechtsstaat - die europ{\"a}ische Integration und die Mitgliedstaaten. Entwickelt wird eine Vision der Europ{\"a}ischen Union, die statt auf fortschreitender Zentralisierung st{\"a}rker auf einer gleichberechtigten Kooperation der Mitgliedstaaten basiert. Die nationalen Verfassungsidentit{\"a}ten sollen als unentbehrliche Bestandteile der nationalen Souver{\"a}nit{\"a}t nicht der europ{\"a}ischen Integration geopfert werden. Vor allem der Grundsatz vom Vorrang des Unionsrechts wird in diesem Zusammenhang kritisch hinterfragt. „Integrationswut" gelte es zu verhindern. Die Rechtsstaatlichkeit einzelner Mitgliedstaaten d{\"u}rfe durch die Union nicht infrage gestellt werden. In seiner Abschlussvorlesung geht Detlev W. Belling der Frage nach, ob und inwieweit die Aus{\"u}bung der Gnadenbefugnisse durch die Gnadentr{\"a}ger in einem s{\"a}kularen und republikanischen Rechtsstaat der gerichtlichen Kontrolle unterliegen sollte. Detailliert werden in diesem Zusammenhang nicht nur die bisherige Rechtsprechung des Bundesverfassungsgerichts und das breit gef{\"a}cherte Meinungsspektrum der Literatur abgebildet. Anhand einer Vielzahl von Beispielen aus der ferneren und unmittelbaren Geschichte wird die Entwicklung des Gnadenrechts nachgezeichnet. Missbrauchsgefahren, wie sie nicht nur kennzeichnend f{\"u}r Diktaturen und Monarchien sind, werden aufgezeigt. Die Erkenntnisse aus der historischen Darstellung aufgreifend, wird anhand einer umfassenden Analyse der geltenden Rechtslage nachgewiesen, aus welchen Gr{\"u}nden die Konstitutionalisierung des Begnadigungsrechts geboten ist.},

  abstract  = {Defining the allocation of decision rights for enterprise applications is a crucial issue in IT governance and organization design. Today, emerging delivery models such as Software as a Service (SaaS) defy the notion of the internal IT department as the focal point of centralized governance. Recognizing the importance of this issue, we find that the phenomenon of 'SaaS governance' itself is not yet well understood. Based on two cases of SaaS adoption, we take a process-theoretic approach to investigate the complex interaction between factors that influence in the allocation of SaaS authority. The results suggest that some factors, such as the locus of initiative and the decision for SaaS, interact with absorptive capacities and determine the later mode of application governance at a very early stage. Thus, the initiative for introducing SaaS emerges as an important intermediate variable between the overall IT governance mode and the resulting SaaS governance outcome.},

In recent years, the Business Process Model and Notation (BPMN) evolved into the leading standard for process modeling. However, BPMN is complex: The specification offers a huge variety of different elements and often several representational choices for the same semantics. This raises the question of how well modelers can deal with these choices. Empirical insights into BPMN usage from the perspective of practitioners are still missing. We close this gap by analyzing a large set of BPMN 2.0 process models from practice. We found that particularly representational choices for splits and joins, the correct use of message flow, the proper decomposition of models, and the consistent labeling appear to be connected with quality issues. Based on our findings we give five recommendations how these issues can be avoided in the future. The work summarized in this extended abstract has been published in [LMG16].},

Following a qualitative study, we conducted an experiment in which 653 participants were presented with website screenshots featuring varying levels of Likes and Dislikes. The results indicate that the theoretical framing of Likes as a Signal is valid and that people do perceive the quality of products and services as superior when they are associated with more Likes. Signaling also explains the counter-intuitive finding that Dislikes can have a positive effect on people's quality perceptions. Results are discussed with respect to theory and practical implications.},
