This study examined the level of trust of information on social media. Specifically, I investigated the factors of performance expectancy with information-seeking motives that appear to influence the level of trust of information on various social network sites. This study utilized the following theoretical models: elaboration likelihood model (ELM), the uses and gratifications theory (UGT), the unified theory of acceptance and use of technology model (UTAUT), the consumption value theory (CVT), and the Stimulus-Organism-Response (SOR) Model to build a conceptual research framework for an exploratory study. The research investigated the extent to which information quality and source credibility influence the level of trust of information by visitors to the social network sites. The inductive content analysis on 189 respondents’ responses carefully addressed the proposed research questions and then further developed a comprehensive framework. The findings of this study contribute to the current research stream on information quality, fake news, and IT adoption as they relate to social media.

Das Interuniversitäre Doktorandenseminar Wirtschaftsinformatik ist eine regelmäßige Veranstaltung, in deren Rahmen Doktoranden der Universitäten Chemnitz, Dresden, Freiberg, Halle, Ilmenau, Jena und Leipzig ihr Promotionsprojekt präsentieren und sich den kritischen Fragen der anwesenden Professoren und Doktoranden aller beteiligten Universitäten stellen. Auf diese Weise erhalten die Promovierenden wertvolles Feedback zu Vorgehen, Methodik und inhaltlichen Aspekten ihrer Arbeit, welches sie für ihre Promotion nutzen können. Darüber hinaus bietet das Interuniversitäre Doktorandenseminar Wirtschaftsinformatik eine Plattform für eine fachliche Auseinandersetzung mit aktuellen Themen und sich ankündigenden Trends in der Forschung der Wirtschaftsinformatik. Zudem wird ein akademischer Diskurs über die Grenzen der jeweils eigenen Schwerpunkte der Professur hinaus ermöglicht. Das nunmehr 20. Jubiläum des Doktorandenseminars fand in Chemnitz statt. Der daraus entstandene Tagungsband enthält fünf ausgewählte Beiträge zu den Themenfeldern Service Engineering, Cloud-Computing, Geschäftsprozessmanagement, Requirements Engineering, Analytics und Datenqualität und zeigt damit anschaulich die Aktualität und Relevanz, aber auch die thematische Breite der gegenwärtigen Forschung im Bereich Wirtschaftsinformatik. / The inter-university PhD seminar Business Information Systems (“Interuniversitäres Doktorandenseminar Wirtschaftsinformatik”) is an annual one-day event which is organized by the Business Information Systems chairs of the universities of Chemnitz, Dresden, Freiberg, Halle, Ilmenau, Jena and Leipzig. It serves as a platform for PhD students to present their PhD topic and the current status of the thesis. Therefore, the seminar is a good opportunity to gain further knowledge and inspiration based on the feedback and questions of the participating professors and students. The 20th Interuniversitäre Doktorandenseminar Wirtschaftsinformatik took place in Chemnitz in October 2016. The resulting proceedings include five selected articles within the following topic areas: service engineering, cloud computing, business process management, requirements engineering, analytics und data quality. They illustrate the relevance as well as the broad range of topics in current business information systems research. In case of questions and comments, please use the contact details at the end of the articles.

The present study examines General Deterrence Theory (GDT) and its "parent," Rational Choice Theory (RCT), in an information security setting, assessing the behavioral intent to violate organizational policy under varying levels of certainty, severity and celerity of negative sanction. Also assessed is the individual computer user's time orientation, as measured by the Consideration of Future Consequences (CFC) instrument (Strathman et. al, 1994). How does rational consideration of violation rewards influence the impact of sanctions on individuals? How does time orientation impact intent to violate security policy? How do these operate in an IS context? These questions are examined by assessing the responses of university students (N = 443) to experimental manipulations of sanctions and rewards. Answering vignettes with the factorial survey method, intent to violate is assessed in a setting of Internet piracy of electronic textbooks while being monitored by computer security systems. Findings show that, although traditional GDT variables and reward impact intent to violate, CFC does not cause the hypothesized moderating effect on these variables. However, post-hoc analysis reveals a direct effect of time orientation on behavioral intent, as well as a weak moderating effect opposite of the hypotheses, indicating increased time orientation positively moderates, rather than negatively moderates, the impact of reward on intent to violate. Implications for theory and practice, and future research directions, are discussed.
