Zusammenfassung. Wir pr?sentieren ein Managementsystem, das insbesondere hinsichtlich der Dynamik von Entwicklungsprozessen über die Funktionalit?t kommerzieller Systeme zum Projektmanagement, Workflowmanagement und Engineering Data Management hinausgeht. AHEAD (Adaptable and Human-CenteredEnvironment for the MAnagement of Development Processes) unterstützt die Koordination von Entwicklern durch integriertes Management von Produkten, Aktivit?ten und Ressourcen. Für das Management von Aktivit?ten werden dynamische Aufgabennetze angeboten, die sich durch nahtloses Verschr?nken von Planen, Analysieren und Ausführen auszeichnen. Alle Managementdaten (z.B. Aufgabennetze, Versionshistorien oder Produktkonfigurationen) werden intern in einheitlicher Weise durch Graphen repr?sentiert. Managementwerkzeuge werden aus einer formalen Spezifikation generiert, die auf programmierten Graphersetzungsregeln basiert. Eingegangen am 9. Juni 2000 / Angenommen am 20. M?rz 2001  相似文献

Basic subjects in medical education, such as anatomy, are often taught through teaching formats that do not always sufficiently demonstrate the relevance of this basic information for clinical practice. Accordingly, it is a recent trend in anatomy education to link anatomical information more explicitly to clinical practice. This article presents an online video platform (Tuebingen’s Sectio Chirurgica [TSC]) as one means of explicitly integrating preclinical anatomical knowledge and clinical application. The purpose of the study presented here was to examine the effects of videos through which medical students were educated about Anterior Cruciate Ligament reconstruction. A TSC video about this surgical procedure was compared to a video with a traditional lecture providing the identical information. Participants (n = 114) perceived the TSC video to be superior in comprehensibility of the presentation (P = 0.003) and conceivability of the surgical procedure (P = 0.027), and to be more entertaining (P < 0.001). Moreover, participants in the TSC condition acquired more clinical knowledge than in the lecture condition (P = 0.043) but did not differ in their acquisition of anatomical knowledge. Mediation analyses indicated that the effect on the acquisition of clinical knowledge was mediated by comprehensibility, conceivability, and entertainment. These findings are discussed regarding their implications for medical education in terms of contributing to the general trend of linking preclinical anatomical knowledge to clinical application. A discussion about the limitations of the study and suggestions for future research are also provided.  相似文献

Zur Beherrschung der komplexen vernetzten und verteilten Funktionen von Automotive-Software ist eine Beschreibung des zu erstellenden Systems auf verschiedenen Abstraktionsebenen und schrittweise überg?nge zwischen diesen Ebenen notwendig. Neben der Definition geeigneter Ebenen werden zur Unterstützung echtzeitkritischer Systemanteile ein einheitliches Berechnungsmodell, ebenenspezifische Beschreibungstechniken, sowie methodische Regeln für diese Abstraktionsebenen eingeführt und in den Werkzeugprototypen AutoFocus integriert.  相似文献

Biodiversity science in China has seen rapid growth over recent decades, ranging from baseline biodiversity studies to understanding the processes behind evolution across dynamic regions such as the Qinghai-Tibetan Plateau. We review research, including species catalogues; biodiversity monitoring; the origins, distributions, maintenance and threats to biodiversity; biodiversity-related ecosystem function and services; and species and ecosystems’ responses to global change. Next, we identify priority topics and offer suggestions and priorities for future biodiversity research in China. These priorities include (i) the ecology and biogeography of the Qinghai-Tibetan Plateau and surrounding mountains, and that of subtropical and tropical forests across China; (ii) marine and inland aquatic biodiversity; and (iii) effective conservation and management to identify and maintain synergies between biodiversity and socio-economic development to fulfil China''s vision for becoming an ecological civilization. In addition, we propose three future strategies: (i) translate advanced biodiversity science into practice for biodiversity conservation; (ii) strengthen capacity building and application of advanced technologies, including high-throughput sequencing, genomics and remote sensing; and (iii) strengthen and expand international collaborations. Based on the recent rapid progress of biodiversity research, China is well positioned to become a global leader in biodiversity research in the near future.  相似文献

Thirty‐eight Latin American mothers with young children tell of their perceptions of school discipline and comportment issues and talk of their children's encounters with ‘zero tolerance’ legislation, and related rules for conduct, implemented by the local school boards. The purpose of this exploratory study is to understand: (a) parents' views of and concern about disciplinary practices at school; (b) parents' ideas about the connection between home and school discipline; and (c) parents' understanding of the officially prescribed consequences of behaviour identified as non‐tolerable. Implications of the findings are discussed with regard to professional practice.  相似文献
