Die Festsetzungspraxis des GKV-Spitzenverbands im Festbetragswesen - eine kritische Bestandsaufnahme

This paper presents methods for the reduction and compression of meteorological data for web-based wind flow visualizations, which are tailored to the flow visualization technique. Flow data sets represent a large amount of data and are therefore not well suited for mobile networks with low data throughput rates and high latency. Using the mechanisms introduced in this paper, an efficient transfer of thinned out and compressed data can be achieved, while keeping the accuracy of the visualized information almost at the same quality level as for the original data.
Der Arbeitskreis Usable Security & Privacy bietet ein Forum für den Gedankenaustausch und die interdisziplinäre Zusammenarbeit rund um das Thema benutzerfreundliche Informationssicherheit und privatheitsfördernde Technologien. Sicherheit ist bei der Anschaffung von Software und Technikprodukten zwar eines der zentralen Auswahlkriterien – aufgrund mangelnder Gebrauchstauglichkeit werden die vorhandenen Sicherheitsfunktionen und -mechanismen von den Nutzern jedoch oft falsch oder überhaupt nicht bedient. Im alltäglichen Gebrauch ergeben sich hierdurch Sicherheitsgefährdungen beim Umgang mit IKT-Systemen bzw. -Produkten und den darin enthaltenen sensiblen Daten. Im Workshop werden mit den Teilnehmern Beispiele diskutiert und es wird gemeinsam ein Stimmungsbild zum Verständnis, zum Stellenwert und zum aktuellen Grad der Umsetzung von Usable Security & Privacy erhoben. Ergebnis des Workshops ist ein Positionspapier, in dem die aktuellen Problemfelder und die wichtigsten Herausforderungen aus Sicht der Usability und UX Professionals beschrieben sind.
In this paper, we introduce the international program erp4students as general example on how to successfully prepare university students for the world of works without having to give up the basic principle in higher education, i.e., to exclusively provide sustainable education. We start with introducing the basic concept and design of the program and provide information regarding the demographic development over the past decade and implemented quality assurance mechanisms. Subsequently, the scope and design of and hitherto achieved insights from the Learning Culture Survey are outlined. On the basis of found results, we finally discuss how erp4students can deal with possible culture-specific issues that latest might emerge when the program gets available for learners in the Asian context.

Basic demand from enterprises towards academic education: provide students not only methodological/theoretical knowledge, but also prepare them for the future tasks in the world of works! This contradicts academia’s focus on sustainably teaching basic principles. With the extra-curricular international online program erp4students, we successfully managed to bridge this "conflict-of-interest”.
Job-related migration has been fostered across Europe balancing unemployment in one country with demands for employees in others. However, the numbers of early school leavers and university dropouts significantly increased in the hosting countries. We propose a higher measure of cultural sensitivity in education in order to prevent frustration. The Learning Culture Survey investigates learners’ expectations towards and perceptions of education on international level with the aim to make culture in the context of education better understandable. After a brief introduction, we subsume the steps taken during the past seven years and found results. Subsequently, we introduce a method for the determination of conflict potential, which bases on the understanding of culture as the level to which people within a society accept deviations from the usual. We close with demonstrating the usefulness of the data and insights from our Learning Culture Survey in the context of practical scenarios.
The aim of design science research (DSR) in information systems is the user-centred creation of IT-artifacts with regard to specific social environments. For culture research in the field, which is necessary for a proper localization of IT-artifacts, models and research approaches from social sciences usually are adopted. Descriptive dimension-based culture models most commonly are applied for this purpose, which assume culture being a national phenomenon and tend to reduce it to basic values. Such models are useful for investigations in behavioural culture research because it aims to isolate, describe and explain culture-specific attitudes and characteristics within a selected society. In contrast, with the necessity to deduce concrete decisions for artifact-design, research results from DSR need to go beyond this aim. As hypothesis, this contribution generally questions the applicability of such generic culture dimensions’ models for DSR and focuses on their theoretical foundation, which goes back to Hofstede’s conceptual Onion Model of Culture. The herein applied literature-based analysis confirms the hypothesis. Consequently, an alternative conceptual culture model is being introduced and discussed as theoretical foundation for culture research in DSR.
