This paper introduces and empirically illustrates a pedagogical approach to teaching Public Relations (PR) in higher education. The approach is based on the Communities of Practice theory (Wenger, 1998). Based on this theory and for the purposes of this paper, learning is perceived as (1) a participation in a practice of (2) a social community and (3) the understanding of this practice. The pedagogical approach to teaching PR entails the facilitation of these three elements. The approach is illustrated through a case study. The authors conducted an international undergraduate course to teach students how to conduct a social media campaign to raise engagement for social issues. Twenty students from Netherlands and Germany enrolled. The paper offers an integrated understanding of theory and practice (see Wenger, 1998, p. 48). It contrasts many current approaches in PR education, which tend to differentiate between PR theory and practice. PR educators are encouraged to facilitate an equal negotiation between theory and practice and to enable students to match whatever is theorised with practice and whatever is practiced with theory.
The Internet of Things (IoT) relies on sensor devices to measure real-world phenomena in order to provide IoT services. The sensor readings are shared with multiple entities, such as IoT services, other IoT devices or other third parties. The collected data may be sensitive and include personal information. To protect the privacy of the users, the data needs to be protected through an encryption algorithm. For sharing cryptographic cipher-texts with a group of users Attribute-Based Encryption (ABE) is well suited, as it does not require to create group keys. However, the creation of ABE cipher-texts is slow when executed on resource constraint devices, such as IoT sensors. In this paper, we present a modification of an ABE scheme, which not only allows to encrypt data efficiently using ABE, but also reduces the size of the cipher-text, that must be transmitted by the sensor. We also show how our modification can be used to realise an instantaneous key revocation mechanism.
The Osnabrueck University of Applied Sciences has initiated a project to investigate whether and how dual study programs or even elements of it can be integrated into South African university study programs. The present part of the investigation presents the expert assessments of the demands and requirements for dual study programs and, based on a company survey, the existing level of information.
The significance of dual study programs in South Africa is still low, only a few company specific approaches exist, mostly in internationally operating companies. Nevertheless, closer cooperation and more company orientated learning is required. The willingness to participate in dual study programs was confirmed from all surveyed companies. Dual courses seems to be particularly suitable for technical disciplines, but are also suitable for some business courses.
In idea creation and assessment processes the accruement and the description of an idea are mostly allocated to a fixed point in time, defined as the end of the generating process and the start of the idea assessment. This static approach does not fit the reality in industrial idea processes. A dynamic approach for idea assessment is therefore introduced. An idea is not seen as a static but as a dynamic state, characterized by different degrees of maturity. Maturity is understood as a measure of the assessability of the individual evaluation characteristics.
Based on Crosby’s maturity model and on classical Capability Maturity Models, a new Idea Maturity Model (IMM) has been developed and is introduced for the first time. The five Idea Maturity Levels (IML) are named Initial, Awareness, Appraisability, Valuation, and Realisability and harmonize well with other maturity models. The levels are described by general characteristics, although the development of the maturity model focussed on new product or service development. The compatibility of the IMM with idea assessment processes and conditions in organisations and companies has been checked.
Theater und Klinik! Zwei Wörter, die zunächst nicht zusammenpassen wollen. Das Forschungsprojekt „Entwicklung einer Systematik von theaterpädagogischen Arbeitsformaten“ untersuchte im ersten Halbjahr 2018, im Rahmen der „Theaterklinik Lingen“, in welchen Formaten sich gelingende theaterpädagogische Arbeit im Kosmos Krankenhaus konstituiert.
Stromspeicher sind eine mögliche Flexibilitätsoption, um den Anteil fluktuierender Stromquellen aus erneuerbaren Energien im Stromsystem zu erhöhen. In der Vergangenheit wurde vor allem Haushalts- und Großspeichern große Aufmerksamkeit gewidmet. Quartierspeicherlösungen auf der Meso-Ebene werden bislang weitestgehend vernachlässigt. Lediglich im Kontext der Mieterstromdebatte wurden Quartierlösungen zuletzt verstärkt diskutiert. Der vorliegende Artikel geht im Kern der Frage nach, welche Herausforderungen sich im Kontext der Umsetzung von Stromspeichern auf Quartierebene derzeit in Deutschland ergeben. Dazu erfolgt zunächst eine Diskussion und Abgrenzung
des Begriffs Quartierspeicher. Anschließend werden wirtschaftlich-rechtliche und sozio-kulturelle als zentrale Herausforderungen bei der Umsetzung von Quartierspeicherlösungen in Deutschland vorgelegt und diskutiert. Aufbauend auf die Diskussion der aktuellen Herausforderungen werden dann mögliche Geschäftsmodelle zur Umsetzung und zum Betrieb von Quartierspeichern in Deutschland abgeleitet.
