- Abstract
- The proliferation of digital knowledge repositories (DKRs) used for distributed and collocated work raises important questions about how to manage these technologies. This study investigates why individuals contribute information to DKRs by applying and extending transactive memory theory. Data from knowledge workers (N = 208) nested in work groups (J = 17) located in Europe and the United States revealed, consistent with transactive memory theory, that perceptions of experts' retrieval of information were positively related to the likelihood of information provision to DKRs. The relationship between experts' perceptions of retrieval and information provision varied from group to group, and cross-level interactions indicated that trust in how the information would be used and the interdependence of tasks within groups could explain that variation. Furthermore, information provision to DKRs was related to communication networks in ways consistent with theorizing regarding the formation of transactive memory systems. Implications for theory and practice are discussed, emphasizing the utility of multilevel approaches for conceptualizing and modeling why individuals provide information to DKRs.

- Abstract
- This study investigated how people comprehend three-dimensional (3D) visualizations and what properties of such visualizations affect comprehension. Participants were asked to draw the face of a 3D visualization after it was cut in half. We videotaped the participants as they drew, erased, verbalized their thoughts, gestured, and moved about a two-dimensional paper presentation of the 3D visualization. The videorecords were analyzed using a grounded theory approach to generate hypotheses related to comprehension difficulties and visualization properties. Our analysis of the results uncovered three properties that made problem solving more difficult for participants. These were: (a) cuts that were at an angle in relation to at least one plane of reference, (b) nonplanar properties of the features contained in the 3D visualizations including curved layers and v-shaped layers, and (c) mixed combinations of layers. In contrast, (a) cutting planes that were perpendicular or parallel to the 3D visualization diagram's planes of reference, (b) internal features that were flat/planar, and (c) homogeneous layers were easier to comprehend. This research has direct implications for the generation and use of 3D information visualizations in that it suggests design features to include and avoid.

- Abstract
- Dieser Artikel beschäftigt sich mit den Möglichkeiten der Informationsaufbereitung durch computergenerierte dreidimensionale Elemente. Visualisierungen durch 3DGrafiken und Animationen können im Vergleich zum Informationsgehalt andersartiger Darstellungen einen kommunikativen Mehrwert aufweisen, der den höheren Aufwand der Erzeugung rechtfertigt. Es wird die Frage aufgeworfen, in welchen Forschungsgebieten der Informationswissenschaft und Medieninformatik der Einsatz von räumlichen Repräsentationen angebracht ist und inwieweit sich die Fokussierung auf eine Informationsübermittlung durch eine virtuelle 3D-Umgebung mit den gesteigerten Anforderungen an das Kommunikationssystem in Einklang bringen lässt. Durch die menschliche Ausrichtung auf möglichst natürliche und realistische Erscheinungen bei der Informationsaufnahme ist die Verwendung der dritten Dimension im Kommunikationsprozess ausgenommen hilfreich, es bedarf zuvor allerdings einer Konzeption geeigneter Einsatzprinzipien, die der großflächigen Anwendung im Bedarfsfall gerecht werden.
