The term knowledge management (KM) has lost most of its magic during the past few years: While knowledge has been identified as an important resource and key factor for productivity gains and innovation in organizations, there seems to be no generally applicable (and easy) way to utilize this resource. In this paper we present results of a field study that(More)
White-nose syndrome is an emerging disease in North America that has caused substantial declines in hibernating bats. A recently identified fungus (Geomyces destructans) causes skin lesions that are characteristic of this disease. Typical signs of this infection were not observed in bats in North America before white-nose syndrome was detected. However,(More)

Species are being lost at increasing rates due to anthropogenic effects, leading to the recognition that we are witnessing the onset of a sixth mass extinction. Emerging infectious disease has been shown to increase species loss and any attempts to reduce extinction rates need to squarely confront this challenge. Here, we develop a procedure for identifying(More)
Recent knowledge management initiatives focus on expertise sharing within formal organizational units and informal communities of practice. Expert recommender systems seem to be a promising tool in support of these initiatives. This paper presents experiences in designing an expert recommender system for a knowledge-intensive organization, namely the(More)
BACKGROUND Species Distribution Models (SDMs) aim on the characterization of a species' ecological niche and project it into geographic space. The result is a map of the species' potential distribution, which is, for instance, helpful to predict the capability of alien invasive species. With regard to alien invasive species, recently several authors(More)
Dated molecular phylogenies are often used to interpret evolutionary history with respect to paleogeographic events. Where more than one interpretation is possible, it is desirable but difficult to assess the alternatives in an objective manner. The present work demonstrates a formalized method for testing molecular clock calibrations and biogeographic(More)
The range size of a species can be determined by its current traits and by phylogenetic and biogeographic factors. However, only rarely have these factors been studied in combination. We use data on the geographic range sizes of all 26 Sylvia warblers to explicitly test whether range size was determined by current species-specific traits (e.g., body size,(More)
A Computer Club House (CCH) can be understood as a community of prosumers in which members are producing and consuming personally meaningful artifacts of each other. In a long term case study, we have analyzed learning practices in a German CCH setting. Observing children and their parents working with construction kits, we found that they had problems in(More)
Detecting the factors that determine the interruption of gene flow between populations is key to understanding how speciation occurs. In this context, caves are an excellent system for studying processes of colonization, differentiation and speciation, since they represent discrete geographical units often with known geological histories. Here, we asked(More)
Research on the adoption of information systems (IS) often stated technology as a fixed entity. Following the 'practical turn' in IS we argue that information technology artefacts are mainly 'cultural artefacts', which are shaped in a social process of appropriation where software usage is accompanied by processes of interpretation, negotiation or change in(More)
