Abstract: In today's interconnected world, Internet users are increasingly concerned about losing control over the data they share with peers, which indicates a need for higher levels of control and notification mechanisms. We address this need by building on design science methodology and developing a socio-technical artifact, i.e., a peer-privacy-friendly online messaging service. We draw on Malhotra et al.'s (2004) Internet Users' Information Privacy Concerns framework and refine and evaluate our artifact via focus groups, interviews, and a survey among users of online messaging services. Our artifact provides senders with the ability to control how their personal information is processed by peers and allows receivers to be made aware of the sender's privacy expectations. We contribute to the growing literature on peer privacy concerns by developing and evaluating design requirements, principles, and an instantiation that can mitigate peer privacy concerns that go beyond concerns about organizational data practices.

Abstract: E-health systems are often designed without considering user-centered design principles. Past research on the topic of patient-centered e-health (PCEH) has lacked focus on the design and development of a PCEH artifact and the process for its development. In this study, information systems design theory (ISDT) is applied to design, develop, and evaluate an e-health system based on PCEH principles. The goal of the artifact in this study is to improve patient understanding of diagnoses, procedures, medications, and post-discharge instructions and empower patients with the information needed pre-and post-discharge to make informed healthcare decisions. The artifact justification, meta-requirements, meta-design, development, and evaluation are presented in multiple iterationsbeginning with a simple picture book, and ending with a Web-based, mobile, multimedia system. Findings indicate that a PCEH approach can be useful for achieving multiple design goals. The artifact illustrates achievement of an important organizational quality improvement goal for the case study organization involved, a key physician goal to improve patient-physician engagement, and an important patient goal-to improve understanding about patientspecific diagnoses and health conditions prior to discharge from a hospital visit and initiation of home health care.

Abstract: Virtual teams have different interactions than face-to-face teams because they rely on information and communication technologies, which can impede or assist certain human cognitive processes. Past research has shown that although virtual teams exchange more information than face-to-face teams, poor decisions often result, because team members do not consider the unique information they receive from others. Drawing from cognitive psychology, our research explored a unique way to improve team decision-making through the use of cognitive priming. We proposed that priming group members to pay attention to others or to engage in counterfactual thinking would improve team members’ cognition and, therefore, team performance. Prior research with individuals and brainstorming teams has shown these forms of priming to improve performance; however, no research has attempted to use priming to improve the outcomes of virtual team decision-making, which requires deeper interaction and cognitive involvement than brainstorming. We performed two lab experiments using primes that have been found to improve the individual decision-making process. We found that priming had some impact, but it did not significantly improve decision quality. Various reasons are discussed to explain why priming techniques may not be as powerful in teams as in individuals, and future research ideas are suggested to build on our initial work on priming in virtual team decision-making.

Abstract: Past research has suggested that decision-making groups, when communicating face-to-face (FtF), suffered from information sharing biases that affected the quality of the final decision: they tended to discuss previously-shared information before they started to discuss information not known to all, and discussed more of previously-shared than unshared information. In our study we examined these effects in groups that interacted FtF or using a group support system (GSS). Four-member groups discussed a requirements elicitation task in which some requirements were known to all members before starting their discussion, while other requirements were known only to two members of the group. Both GSS and FtF groups exchanged a large percentage of the shared requirements. However, the GSS groups were more effective in communicating unshared requirements. On average, FtF groups discussed shared requirements sooner and unshared requirements later than did GSS groups. Our study also compared empirical results with predictions from an information-sampling model of group discussion in order to assess the effectiveness of the model in computer-mediated group communication.
