Distributed Visual Language Environments for Cooperation and Learning: Applications and Intelligent Support 总被引:1,自引:0,他引:1
H. Ulrich Hoppe Katrin Gaßner Martin Muuml;hlenbrock Frank Tewissen 《Group Decision and Negotiation》2000,9(3):205-220
An increasing number of collaborative learning environments is based on shared workspace systems using two-dimensional graph-structured visual representations such as argumentation networks and concept maps. We propose an integrated framework that allows for flexibly specifying a wide range of visual languages and plugging in components for operational semantics, adequate feedback and intelligent support. The generic application CardBoard provides card-based user interaction and collaboration by means of different languages in shared workspaces. To enhance modifiability, the interfaces between the distributed heterogeneous system components, particularly between intelligent components and user interfaces, have been standardised. 相似文献

Bew?hrte und neue Therapieans?tze zur Behandlung chronischer Wunden – Unter chronischen, schlecht heilenden Wunden leiden in Deutschland etwa 800.000 Menschen. Weil die Erkrankung für den Patienten schwerwiegende Einschr?nkungen im Alltag mit sich bringt, steht eine effektive Wundbehandlung im Zentrum des Interesses. 相似文献

Wenn sich die Beweislast umkehrt - Schlampt das Pflegepersonal in punkto Hygiene muss das Krankenhaus dafür juristisch geradestehen. Unter Umst?nden kehrt sich bei Schadenersatz klagen die Beweislast jedoch um – zum Nachteil des Krankenhaustr?gers. 相似文献

The present studies investigated whether the visual co‐presentation of a brand name and a product visual increases or decreases the acquisition of liking toward these stimuli in a conditioning paradigm. In Study 1, participants were presented with an elemental brand name, an elemental product visual, or a compound of both stimuli, along with liked faces. Results indicated that the mere pairing with the liked face led to increased liking in the elemental condition, but not in the compound condition (i.e., cue competition). Study 2 showed that this effect is due to the divided attention toward the compound, but not due to competition among conditioned stimuli (CSs) to predict the unconditioned stimulus (US). © 2011 Wiley Periodicals, Inc. 相似文献

Sustainability of increasing relevance also for seafood markets. The aim of this contribution is to analyze consumer preferences and their willingness to pay (WTP) for different sustainability claims, and to identify consumer segments according to their WTP. The contingent valuation method was applied to elicit consumers’ WTP in eight European countries. The WTP varies between seven and almost 20%, depending on attribute and country. Three consumer groups become apparent: the largest group without any additional WTP, a smaller group with a moderate additional WTP of plus 17%, and a very small group with an additional WTP of more than 40%. Clear differences between countries are obvious regarding preferences for different sustainability attributes, particularly in the segment with the highest WTP. A fraction of the consumers is willing to pay significantly higher prices for sustainably produced fish from Europe: given that trustful standards are applied and well communicated. 相似文献

To learn and adapt, organizations engage widely in Information Technology (IT)-mediated boundary-spanning. This involves making sense of a swath of peripheral information made available by digital means so as to expand local knowledge. Prior research on boundary-spanning has paid scant attention to material differences between IT systems in enabling or constraining such activity. In this article, we argue that material features do matter: features afforded by IT systems have a significant impact on the form and content of boundary-spanning. We analyze material features and related affordances provided by remote diagnostics systems – a family of ubiquitous IT systems. These features allow remote diagnostics systems to collect, store, and continuously analyze data about the state of machinery and related production processes across space, time and organizational boundaries. Organizations use these systems to determine when maintenance intervention is needed, or to improve their production processes. Often, these systems are run by external service providers at remote sites, which become the new ears and the eyes of a focal organization’s production processes. Building on a longitudinal multi-site case study of two organizations, we explore the impacts of remote diagnostics systems on boundary-spanning. We observe that material features afforded by the remote diagnostics led the organizations to change their boundary-spanning in contradictory ways. On one hand, they reinforced existing boundaries. On the other hand, they crossed or cut down others, or created new ones. This suggests that the material features of these systems, when combined with new knowledge creation and sharing practices, within and between the local and the remote sites generate richer, multi-faceted inter-organizational knowledge flows. We surmise that IT’s new material features will continue to significantly shape organizing logics that determine where and when organizational boundaries are drawn and crossed. Future boundary-spanning will increasingly be shaped by socio-technical assemblages brought together by increasingly pervasive IT capabilities. 相似文献

This paper deals with the question whether the ongoing process of banking consolidation, which can be observed all over the
world, worsens SMEs’ access to credit. We focus in our empirical study on SMEs in Germany, a country where SMEs are the backbone
of the economy. A negative trend in the provision with bank credit may thus adversely affect growth and employment. Based
on a comprehensive dataset on German firms and banks we find—contrary to public fear—that the ongoing banking consolidation
in Germany does not have a significant negative impact on the financing of German firms during the observation period from
1996 to 2002. 相似文献
