PublicationCAN ESCAPIST USE OF FACEBOOK BE TRIGGERED BY FACEBOOK PUSH NOTIFICATION?Type: conference paper
PublicationFacebook Push Notification as Triggers for Habit-Forming Feedback LoopsThis abstract analyses if push notifications of social media (SM) to users lead are the starting point for habit-forming feedback loops according to the hook concept based on the example of Facebook push notifications. Facebook push notifications are conceptualized as starting point of a chain of persuasive offerings that result in Facebook triggered escapism. A push notification is successful, i.e. has high persuasiveness when addressed users react on it, enter the platform and stay longer in Facebook. Thus, through reacting on push notifications users get immersed into Facebook’s entertainment and media offerings, which results in a triggered escapist consumption of the offered content by the platform. The empirical results reveal that self-control is negatively related to triggered Facebook escapism. Usability of push Facebook notifications is positively related to triggered Facebook escapism. Triggered Facebook escapism furthermore results in positive effects for users in term of enjoyment, autonomy, competence and relatedness. It is negatively related to feeling of guilt.

PublicationCSR Communication Strategies for Twitter : Microblogging as a Tool for Public RelationsThis study explores how companies use the social media tool Twitter for CSR communication. By analyzing CSR communication conducted by 30 most central corporate Twitter accounts, identified through social network analysis within a CSR-Twitter-network consisting of 19'855 Twitter members, we contribute to the understanding of Twitter's role for CSR communication and public relations. Manually conducted content analysis of totally 41‘864 corporate Twitter messages gives insights into different strategies concerning intensity and interactivity of CSR communication. Based on theoretical foundations and empirical findings four CSR communication strategies for Twitter are identified.

PublicationSAP Research RoofTop Marketplace( 2009-04-20)
;Hoyer, Volker ;Gilles, Florian ;Fleischmann, Kathrin ;Dreiling, AlexanderEnterprise Mashups have gained momentum in the last years. Business users with no or limited programming skills are empowered to leverage in a collaborative manner existing mashable components. By combining and reusing Web-based resources within minutes, business users are able to create new value added applications to solve an individual and ad-hoc business problem. In this demo, we show the SAP Research RoofTop Marketplace prototype that transfers established marketplace concepts and principles to the Enterprise Mashup paradigm in order to handle business and organizational challenges of the Mashup paradigm in enterprise environments.Type: conference paper
PublicationDesign Principles of Enterprise Mashups(Gesellschaft für Informatik, 2009-03-25)
;Hoyer, Volker ; ;Hinkelmann, KnutWache, HolgerA new kind of Web-based application, known as Enterprise Mashups, has been gaining momentum in the last years. Enterprise Mashups implicate a shift concerning a collaborative software development and consumption process. End users combine and reuse existing Web-based resources within minutes to new value added applications in order to solve an individual and ad-hoc business problem. Novel design principles are currently about to emerge allowing to cover the long tail of user needs. In this position paper, we introduce the terminology used in context of this new paradigm and present an Enterprise Mashup Stack which consists of three layers: Web-based resources, widgets, and Mashups. Based on this model, we elaborate on the design principles of upcoming intermediaries and the mass collaboration form, the lightweight composition style as well as the perpetual beta development model. By means of the EU funded research project FAST, we show their real-world applicability. http://www.km-conference2009.org/workshops/KSM09.phpType: conference paperJournal: Lecture notes in informaticsVolume: 145
