Das AutoMoDe-Projekt Modellbasierte Entwicklung softwareintensiver Systeme im Automobil

Die Entwicklung eingebetteter Software für Automobile ist inh?rent komplex und vereint verschiedene Entwicklungsphasen, mehrere fachliche Disziplinen, sowie verschiedene Akteure in beteiligten Unternehmen. Der AutoMoDe-Ansatz zur Entwicklung automotiver Software beschreibt Systeme auf verschiedenen Abstraktionsebenen und definiert schrittweise überg?nge zwischen diesen Ebenen. Neben der Definition geeigneter Ebenen werden zur Modellierung von Echtzeitsystemen ein einheitliches Berechnungsmodell sowie dom?nenspezifische Beschreibungstechniken verwendet. Automatisierte Anbindungen für Analyse und Synthese komplexer Softwaresysteme mit dem Ziel eines konsistenzbetonten Entwicklungsprozesses wurden realisiert. Die beschriebenen Techniken wurden in den Werkzeugprototypen AutoFocus integriert und im Zusammenspiel mit einer Werkzeugkette demonstriert.     

Quality assurance and its impact from higher education institutions’ perspectives: methodological approaches,experiences and expectations

This paper reports on methodological approaches, experiences and expectations referring to impact analysis of quality assurance from the perspective of three higher education institutions (students, teaching staff, quality managers) from Germany, Finland and Romania. The presentations of the three sample institutions focus on discussing the core characteristics of quality assurance procedures applied and their expected and observed impacts, and how intended and non-intended undesirable ones are measured. It turns out that all sample institutions have already some instruments and sub-procedures in place for impact analysis of quality assurance and all of them are striving for further improvement by applying internal and external quality assurance procedures and impact analyses. Finally, a closer look at the recently revised Standards and Guidelines for Quality Assurance in the European Higher Education Area shows that the European sample institutions are on their way towards coherent quality assurance policies, while there is also room left for further improvement and investigation (for example, in implementing systematic methodologies of impact evaluation and quality policies in general).     

Observing Interprofessional Collaboration: Impact on Attitude and Knowledge Acquisition

Interprofessional collaboration (IPC) in the medical field is an important factor for good clinical outcomes and should be taught as early as in undergraduate medical education. Since implementing IPC training is an organizational challenge, students are often limited in their opportunities to experience real-life IPC. Therefore, an approach where students observe successful IPC activities of role models in an applied anatomical format was proposed. It was studied whether observing IPC activities in undergraduate anatomical education has an impact on both students' attitude toward IPC and on knowledge acquisition. Further, it was examined whether the attitudes and knowledge of students from different medical disciplines were influenced in different ways. Therefore, 75 medical students and thirty-eight physiotherapy students participated in a study with the task of observing a live broadcast of an interprofessional teaching session. Participants were asked about their attitudes toward interprofessional learning, their evaluation of professional responsibilities, and their profession-specific knowledge before and after observing the IPC session. The participants' attitude toward interprofessional learning improved for both groups of students. Moreover, students of physiotherapy adjusted their evaluation of their own and others' professional responsibilities after observing IPC. In both student groups, knowledge increased, in particular, with respect to the field of knowledge in other professions. So, observing IPC can modify students' attitudes and support knowledge acquisition. The implementation of IPC observations provides students from various healthcare disciplines with a clearer impression of professionals' responsibilities and gives learners the opportunity to acquire knowledge from healthcare fields unfamiliar to them.     

Studying enzymatic bioreactions in a millisecond microfluidic flow mixer

In this study, the pre-steady state development of enzymatic bioreactions using a microfluidic mixer is presented. To follow such reactions fast mixing of reagents (enzyme and substrate) is crucial. By using a highly efficient passive micromixer based on multilaminar flow, mixing times in the low millisecond range are reached. Four lamination layers in a shallow channel reduce the diffusion lengths to a few micrometers only, enabling very fast mixing. This was proven by confocal fluorescence measurements in the channel’s cross sectional area. Adjusting the overall flow rate in the 200 μm wide and 900 μm long mixing and observation channel makes it possible to investigate enzyme reactions over several seconds. Further, the device enables changing the enzyme/substrate ratio from 1:1 up to 3:1, while still providing high mixing efficiency, as shown for the enzymatic hydrolysis using β-galactosidase. This way, the early kinetics of the enzyme reaction at multiple enzyme/substrate concentrations can be collected in a very short time (minutes). The fast and easy handling of the mixing device makes it a very powerful and convenient instrument for millisecond temporal analysis of bioreactions.     

Grade der Schriftbeherrschung und subjektiver Lernerfolg bei Teilnehmenden an Alphabetisierungskursen

Low literacy in the adult population has been subject of a broad range of studies in Germany in recent years. The main learning opportunities provided for low literates are courses where reading and writing skills are taught at a basic level. The outcome in terms of improved reading and writing capacity were not a focus of discussion by now. The article presents empirical data showing that there are positive though limited effects of participation in such courses. Additionally, participants’ subjective assessments of their learning achievements are provided. Implications of findings are discussed.     

Development and validity of a Dutch version of the Remote Associates Task: An item-response theory approach

The Remote Associates Test (RAT) developed by Mednick and Mednick (1967) is known as a valid measure of creative convergent thinking. We developed a 30-item version of the RAT in Dutch with high internal consistency (Cronbach's alpha = 0.85) and applied both Classical Test Theory and Item Response Theory (IRT) to provide measures of item difficulty and discriminability, construct validity, and reliability. IRT was further used to construct a shorter version of the RAT, which comprises of 22 items but still shows good reliability and validity—as revealed by its relation to Raven's Advanced Progressive Matrices test, another insight-problem test, and Guilford's Alternative Uses Test.
