Im Rahmen eines Forschungsprojektes gingen die Autorinnen folgender Frage nach: Welche identitätsstiftenden Werte der Siebenbürger Sachsen/Sächsinnen sind heute in Oberösterreich noch wahrnehmbar? Es wurde dazu ein qualitatives Forschungsdesign gewählt. Die Ergebnisse zeigen, dass die Auswanderung, Fluchterfahrung und die Ankunft in Österreich wesentlich die Identitäten dieser Personengruppe bestimmte und noch immer beeinflusst. Es wird aufgezeigt, wie sich die Identitäten über drei Generationen verändert haben und was noch als identitätsstiftend erfahrbar ist. Die Ergebnisse leisten einen Beitrag zur Identitätsforschung und bieten eine gute Möglichkeit Erkenntnisse über die beforschte Zielgruppe hinaus zu generieren.
Recently the use of microRNAs (miRNAs) as biomarkers for a multitude of diseases has gained substantial significance for clinical as well as point-of-care diagnostics. Amongst other challenges, however, it holds the central requirement that the concentration of a given miRNA must be evaluated within the context of other factors in order to unambiguously diagnose one specific disease. In terms of the development of diagnostic methods and devices, this implies an inevitable demand for multiplexing in order to be able to gauge the abundance of several components of interest in a patient’s sample in parallel. In this study, we design and implement different multiplexed versions of our electrochemical microfluidic biosensor by dividing its channel into subsections, creating four novel chip designs for the amplification-free and simultaneous quantification of up to eight miRNAs on the CRISPR-Biosensor X (‘X’ highlighting the multiplexing aspect of the device). We then use a one-step model assay followed by amperometric readout in combination with a 2-minute-stop-flow-protocol to explore the fluidic and mechanical characteristics and limitations of the different versions of the device. The sensor showing the best performance, is subsequently used for the Cas13a-powered proof-of-concept measurement of two miRNAs (miRNA-19b and miRNA-20a) from the miRNA-17∼92 cluster, which is dysregulated in the blood of pediatric medulloblastoma patients. Quantification of the latter, alongside simultaneous negative control measurements are accomplished on the same device. We thereby confirm the applicability of our platform to the challenge of amplification-free, parallel detection of multiple nucleic acids.
With the digitalisation, and the increased connectivity between manufacturing systems emerging in this context, manufacturing is shifting towards decentralised, distributed concepts. Still, for manufacturing scenarios manual input or augmentation of data is required at system boundaries. Especially in distributed manufacturing environments, like Cloud Manufacturing (CMfg) systems, constant changes to the available manufacturing resources and products pose challenges for establishing connections between them. We propose a feature-oriented representation of concepts, especially from the manufacturing domain, which serves as the basis for (semi-) automatically linking, e.g., manufacturing resources and products. This linking methodologies, as well as knowledge inferred using it, is then used to support distributed manufacturing, especially in CMfg environments, and enhance product development. The concepts and methodologies are to be evaluated in a real world learning factory.
Mobility choices - an instrument for precise automatized travel behavior detection & analysis

If left uncontrolled, electric vehicle charging poses severe challenges to distribution grid operation. Resulting issues are expected to be mitigated by charging control. In particular, voltage-based charging control, by relying only on the local measurements of voltage at the point of connection, provides an autonomous communication-free solution. The controller, attached to the charging equipment, compares the measured voltage to a reference voltage and adapts the charging power using a droop control characteristic. We present a systematic study of the voltage-based droop control method for electric vehicles to establish the usability of the method for all the currently available residential electric vehicle charging possibilities considering a wide range of electric vehicle penetrations. Voltage limits are evaluated according to the international standard EN50160, using long-term load flow simulations based on a real distribution grid topology and real load profiles. The results achieved show that the voltage-based droop controller is able to mitigate the under voltage problems completely in distribution grids in cases either deploying low charging power levels or exhibiting low penetration rates. For high charging rates and high penetrations, the control mechanism improves the overall voltage profile, but it does not remedy the under voltage problems completely. The evaluation also shows the controller’s ability to reduce the peak power at the transformer and indicates the impact it has on users due to the reduction in the average charging rates. The outcomes of the paper provide the distribution grid operators an insight on the voltage-based droop control mechanism for the future grid planning and investments.
Gewalt in der Pflege
(2021)
Studien zeigen, dass das medizinisch/pflegerische Personal nach Polizei und Sicherheitsleuten unter allen Berufen am zweithäufigsten am Arbeitsplatz von Aggressions- und Gewaltereignissen betroffen sind und dies hat einen negativen Einfluss auf die Berufszufriedenheit und die Gesundheit der betroffenen Mitarbeiter:innen.
Die Studie „Gewalt in der Pflege“ begründet auf repräsentativer Basis ein Monitoring über das Ausmaß von Gewalt gegenüber Pflegenden in Vorarlberger Pflege- und Betreuungseinrichtungen. Für die Analyse wurde in Anlehnung an bestehende Erhebungsinstrumente in verbale Gewalt (inkl. Drohungen), körperliche Gewalt und sexuelle Gewalt unterschieden.
80 % der Befragten gaben an bereits mindestens einmal in ihrem Berufsleben mit Gewalt konfrontiert gewesen zu sein. 44,1 % von ihnen waren Opfer körperlicher Gewalt in verschiedenen Schweregraden. Auch die Prävalenz von sexueller Gewalt ist in den Pflegeheimen als hoch einzustufen, wobei der Großteil der betroffenen Mitarbeiter:innen Frauen sind. Die Hauptquelle der Gewalt sind die Bewohner:innen, gefolgt von den Angehörigen. Es können verschiedene Gründe und Ursachen für die Gewalt ausgemacht werden. Da sind zunächst gesellschaftliche Entwicklungen, wie ein gesteigerter Erwartungsdruck an die Pflegequalität bei gleichbleibenden Rahmenbedingungen, das zunehmende schwerere Krankheitsbild Bewohner:innen von Alters- und Pflegeheimen, sowie eine hohe Belegungszahl zu nennen. Gewalterfahrungen egal welcher Art sind eine Belastung für das Pflegepersonal.
The increasing digitalisation of daily routines confronts people with frequent privacy decisions. However, obscure data processing often leads to tedious decision-making and results in unreflective choices that unduly compromise privacy. Serious Games could be applied to encourage teenagers and young adults to make more thoughtful privacy decisions. Creating a Serious Game (SG) that promotes privacy awareness while maintaining an engaging gameplay requires, however, a carefully balanced game concept. This study explores the benefits of an online role-playing boardgame as a co-designing activity for creating SGs about privacy. In a between-subjects trial, student groups and educator/researcher groups were taking the roles of player, teacher, researcher and designer to co-design a balanced privacy SG concept. Using predefined design proposal cards or creating their own, students and educators played the online boardgame during a video conference session to generate game ideas, resolve potential conflicts and balance the different SG aspects. The comparative results of the present study indicate that students and educators alike perceive support from role-playing when ideating and balancing SG concepts and are happy with their playfully co-designed game concepts. Implications for supporting SG design with role-playing in remote collaboration scenarios are conclusively synthesised.
