Petkov, Petromil, Kobler, Felix, Foth, Marcus, Medland, Richard and Krcmar, Helmut (2011): Engaging energy saving through motivation-specific social comparison. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 1945-1950. Available online

Comparison is widely used in research projects and commercial products whose goal is to motivate energy saving at home. This research builds on fundamental theories from social psychology in an attempt to shed light on how to motivate consumers to conserve energy by providing relevant people for social comparison depending on consumer's motivation to compare. To support the research process, the mobile application EnergyWiz was developed through a theory-driven design approach. Along with other features EnergyWiz provides users with three types of social comparison -- normative, one-on-one and ranking. The results of interviews with prospective users are used to derive design suggestions for relevant people for comparison (comparison subjects).

Leimeister, Jan Marco, Sidiras, Pascal and Krcmar, Helmut (2006): Exploring Success Factors of Virtual Communities: The Perspectives of Members and Operators. In Journal of Organizational Computing and Electronic Commerce, 16 (3) pp. 279-300.

Virtual communities have been the focus of research for some time. However, although many studies have provided recommendations on how to build, extend, and manage virtual communities, few have verified the success factors they have considered essential for virtual communities. Conclusions made regarding basic preferences and distinct priorities of different stakeholders in virtual communities have not been empirically substantiated. Building on previous work on success factors of virtual communities, in this article, we present a ranking of success factors discussed in the literature based on an online survey among operators and members of virtual communities in the German speaking Internet. Consequently, we identified and analyzed incongruencies between members and operators. This research gains first empirically validated insights into success factors for establishing and managing virtual communities. We derived recommendations for operators of virtual communities on the basis of the findings, and we present an agenda for future research in the field.
