As Information Technology (IT) has become increasingly important to the competitive position of firms, managers have grown more sensitive to their organization's overall IT risk management. Recent publicity concerning losses incurred by companies becauseofproblcms with their sophisticated information systems has focused attention on the importance of these systems to the organization. In an att...

Twitter has become a major source of data for social media researchers. One important aspect of Twitter not previously considered are deletions – removal of tweets from the stream. Deletions can be due to a multitude of reasons such as privacy concerns, rashness or attempts to undo public statements. We show how deletions can be automatically predicted ahead of time and analyse which tweets are...

We present a solution for modeling the dependencies of an IT infrastructure and determine the availability of components and services therein using Markov logic networks (MLN). MLNs offer a single representation of probability and first-order logic and are well suited to model dependencies and threats. We identify different kinds of dependency and show how they can be translated into an MLN. Th...

A risk inventory provides an integrated view on risk management artifacts, e.g., risks, risk controls, and performance indicators. In this paper, we show how adapting the enterprise architecture management processes (EAM) may provide a foundation for an integrated IT risk inventory. Based on a design research approach, we develop a systematic approach for integrating the disciplines of risk man...

Customization has been widely studied in the context of information systems and interfaces, but research on customization human-robot interaction (HRI) is scarce. However, user involvement may exert positive effects regarding attitudes trust toward robots, hence improving HRI quality. The aim present work to contribute theoretical understanding by testing whether (none, low, or high) a robot wo...
