Organizations encourage active knowledge retrieval from knowledge management systems; however, this does not always lead to higher work efficiency. Anchoring on uses and gratifications theory and psychology of sunk cost, this study investigates knowledge workers' knowledge retrieval behavior and its subsequent impact on their work efficiency under three knowledge management systems, which differ in the creators of the systems and their related contents. Survey and interview data were collected from an IT call-center company. The results show knowledge workers who actively retrieved knowledge from the organization-created system that contains self-created content exhibited higher work efficiency. The results also show they obtained gratifications from actively retrieving knowledge from a self-made system; however, due to the workers' biased perceptions toward that system, knowledge retrieval from a self-made system did not induce higher work efficiency. The findings provide organizations suggestions for designing knowledge management systems and their related contents.

Abstract:Knowledge reuse is of increasing importance for organizations. Despite the extant research, we still do not adequately understand the ways peers are motivated to reuse knowledge with the help of wiki technologies. In this paper, we study the motivation for knowledge reuse in a prominent instance of online social production: Wikipedia. Studying knowledge reuse in Wikipedia is important since Wikipedia has been able to leverage the benefits of efficient knowledge reuse to produce knowledge goods of relatively high quality. Specifically, we explore: 1) how Wikipedia editors (any peer who contributes to developing articles in Wikipedia) communicate their feedback toward each other's work in peer conversations and 2) to what extent sentiment-driven feedback impacts the level of knowledge reuse in Wikipedia. The results show that displaying sentiment-driven feedback positively influenced the level of knowledge reuse. Our study further shows a significant difference in the level of knowledge reuse between editors who shared mainly positive or mainly negative sentiments. Specifically, displaying mainly positive feedback corresponded to a superior level of knowledge reuse than displaying mainly negative feedback. We contribute to the extant literature of online social production communities in general and Wikipedia in particular by providing a first building block for research on peer feedback's role in developing and sustaining wiki-based knowledge reuse. We discuss our findings' implications for theory and practice.

In Anlehnung an die berühmte Kontroverse zwischen Nobert Elias und Hans Peter Duerr um die Frage der Entstehung der Schamgrenzen im Verhältnis von Körper und Kultur wendet sich dieser Sammelband in inter- und transdisziplinärer Weise der 'Nacktheit im Mittelalter' zu. In 18 Beiträgen aus der gesamten Bandbreite geisteswissenschaftlicher Disziplinen (Geschichte, Islamwissenschaften, Kunstgeschichte, Latinistik, Literaturwissenschaften, Theologie und Philosophie) werden verschiedenste Aspekte entblößter Körper behandelt und umfassend, teilweise mit reichem Bildmaterial dargestellt.
