Qualitätsmanagement und Leistungsmessung im staatlichen Bildungssektor aus Sicht des Controlling

Günther, Thomas, Zurwehme, Annikka 01 June 2003 (has links)
Der Beitrag beschäftigt sich mit der Frage nach adäquater Steuerung staatlicher Bildungseinrichtungen. Als Ausgangsbasis dient dabei die Diskussion um Leistungsmessung und Qualitätsmanagement in Schulen, da hier bereits umfassende Überlegungen zu möglichen Mess- und Steuerungskriterien für Schulen angestellt wurden. Basierend auf einem umfassenden Definitionsansatz für Schulqualität, werden verschiedene Instrumente vorgestellt, die vielfach Erwähnung im Zusammenhang mit Qualitätsmanagement in Schulen finden. Diese werden kurz anhand ihrer grundsätzlichen Zielvorstellung sowie wesentlicher Verfahrens-schritte vorgestellt und einer anschließenden Bewertung unterzogen. Auf Basis der betrachteten Instrumente sowie wesentlicher Grundprinzipien aus dem Controlling werden verschiedene Anforderungen für wirksame Qualitätssysteme in Schulen festgelegt. Abschließend wird das Controlling-Instrument der Balanced Scorecard als mögliches Qualitätsmanagement-System für Schulen in die bestehenden Überlegungen integriert und ihr Nutzen für die kombinierte Anwendung mit anderen Modellen herausgearbeitet.

Description Logics with Aggregates and Concrete Domains, Part II

Baader, Franz, Sattler, Ulrike 19 May 2022 (has links)
We extend different Description Logics by concrete domains (such as integers and reals) and by aggregation functions over these domains (such as min,max,count,sum), which are usually available in database systems. We present decision procedures for the inference problems satisfiability for these Logics-provided that the concrete domain is not too expressive. An example of such a concrete domain is the set of (nonnegative) integers with comparisons (=,≤, ≤n, ...) and the aggregation functions min, max, count. / This is a new, extended version of a report with the same number. An abridged version has appeared in the Proceedings of the European Conference on Artificial Intelligence, Brighton, UK, 1998.

Optimal color channel combination across skin tones for remote heart rate measurement in camera-based photoplethysmography

Ernst, Hannes, Scherpf, Matthieu, Malberg, Hagen, Schmidt, Martin 16 September 2022 (has links)
Objective: The heart rate is an essential vital sign that can be measured remotely with camera-based photoplethysmography (cbPPG). Systems for cbPPG typically use cameras that deliver red, green, and blue (RGB) channels. The combination of these channels has been proven to increase signal-to-noise ratio (SNR) and heart rate measurement accuracy (ACC). However, many combinations remain untested, the comparison of proposed combinations on large datasets is insufficiently investigated, and the interplay with skin tone is rarely addressed. Methods: Eight regions of interest and eight color spaces with a total of 25 color channels were compared in terms of ACC and SNR based on the Binghamton-Pittsburgh-RPI Multimodal Spontaneous Emotion Database (BP4D+). Additionally, two systematic grid searches were performed to evaluate ACC in the space of linear combinations of the RGB channels. Results: Glabella and forehead regions of interest provided highest ACC (up to 74.1 %) and SNR (> -3 dB) with the hue channel H from HSV color space and the chrominance channel Q from NTSC color space. The grid searches revealed a global optimum of linear RGB combinations (ACC: 79.2 %). This optimum occurred for all skin tones, although ACC dropped for darker skin tones. Conclusion: Through systematic grid searches we were able to identify the skin tone independent optimal linear RGB color combination for measuring heart rate with cbPPG. Our results proved on a large dataset that the identified optimum outperformed conventionally used color channels. Significance: The presented findings provide useful evidence for future considerations of algorithmic approaches for cbPPG.
