Sampling Plans for Control-Inspection Schemes Under Independent and Dependent Sampling Designs With Applications to Photovoltaics
The evaluation of produced items at the time of delivery is, in practice,
usually amended by at least one inspection at later time points. We extend the
methodology of acceptance sampling for variables for arbitrary unknown
distributions when additional sampling infor- mation is available to such
settings. Based on appropriate approximations of the operating characteristic,
we derive new acceptance sampling plans that control the overall operating
characteristic. The results cover the case of independent sampling as well as
the case of dependent sampling. In particular, we study a modified panel
sampling design and the case of spatial batch sampling. The latter is advisable
in photovoltaic field monitoring studies, since it allows to detect and analyze
local clusters of degraded or damaged modules. Some finite sample properties
are examined by a simulation study, focusing on the accuracy of estimation
A change process initiated by the "e": How students at Hamburg University learn to manage their e-moderators. A case study
E-learning or online learning within university education in many cases still means provision of written material focusing on the means of refreshing and revisioning lectures and seminars as well as offering add-ons for specific subjects. [...] In this paper [the authors] will discuss some interesting observations and outcomes on the undergraduate students’ perceptions of this concept and compare these with postgraduate participants’ who have at least 1-2 years working experience in business. The observations are based on the author’s own active moderation in three course presentations for undergraduates from 2009 onwards as well as the moderation of numerous elearning courses for professionals.

Ein Weiterbildungsprojekt als Promotor von Hochschulentwicklung – Realität oder Größenwahn
In diesem Beitrag werden die Besonderheiten des BLK-Projektes OLIM1 in Bezug auf die Implementierung von Nachhaltigkeit und die Entwicklungsimpulse aus der Weiterbildung in die Hochschulen hinein dargestellt. Ausgehend von der besonderen Situation in Hamburg und in der Arbeitsstelle für wissenschaftliche Weiterbildung der Universität Hamburg wird das Projekt in seinen wesentlichen Zügen skizziert. Es schließt sich eine Darstellung wichtiger Faktoren zum angestrebten Ziel Nachhaltigkeit sowie eine Beschreibung ihres konzeptionellen Beitrags an. Am Beispiel erster Projektergebnisse wird aufgezeigt, inwiefern sich die hohen Erwartungen bisher erfüllt haben oder ob es sich um einen Anflug von Größenwahn einer kleinen Einrichtung in einer großen Universität handelt.
