Wenn Daten redundant in heterogenen Systemen gespeichert sind, dann wird für die Integration der Daten eine geeignete Replikationsstrategie benötigt. Die hier vorgestellte regelbasierte Replikationsstrategie RegRess erlaubt eine Konfiguration durch Replikationsregeln und eine Adaption zur Laufzeit, weil bei der Inferenz, durch die Schreibund Lesezugriffe koordiniert werden, Systemzustände berüc...

The relations between rationality and optimization have been widely discussed in the wake of Herbert Simon’s work, with the common conclusion that the rationality concept does not imply the optimization principle. The paper is partly concerned with adding evidence for this view, but its main, more challenging objective is to question the converse implication from optimization to rationality, wh...

Despite widespread and long-standing commitment to the notion of critical reflection across the healthcare professions, it is unusual for the theory and practice of critical reflection to be taught as a subject in Higher Education. There is good evidence to show that reflective techniques such as critical portfolios and reflective diaries can help students to consolidate and assess their learni...

According to the „experimenter‟s regress‟, disputes about the validity of experimental results cannot be closed by objective facts because no conclusive criteria other than the outcome of the experiment itself exist for deciding whether the experimental apparatus was functioning properly or not. Given the frequent characterization of simulations as „computer experiments‟, one might worry that a...

This study divides a production system into three components: production design, demand support, and operations. Efficiency is then decomposed via network data envelopment analysis and integrated into the Malmquist Productivity Index framework to develop a more detailed decomposition of productivity change. The proposed model can identify the demand effect and the identity of the root cause of ...

This essay develops and defends a diagnosis of Carroll’s (Mind 4(14):278–280, 1895) regress the premises according to which moral is that arguments are constitutively presuppositional. It argued this allows vindicate key insights rule-following account regress, while overcoming main difficulties faces.

MTW9, a transplantable mammary tumor in Wistar Furth rats, shows little growth unless host serum prolactin is increased. This study compares the response to ovariectomy of MTW9-MtT, a tumor developed in rats bearing the mammosomatotropic tumor MtTW10 (serum prolactin 500 to 7000 ng/ml) with MTW9-P developed in rats given chronic perphenazine treatment (4 mg/kg/day). Serum prolactin concentratio...
