The present study assesses knowledge and knowledge acquisition regarding CSA in social work undergraduate students in a cross-sectional design. Three options for acquisition were assumed: 1) professional education, 2) media consumption, or 3) own experiences of CSA. Results indicated no improvement of knowledge through any of the prior mentioned sources and a high variability in knowledge. In contrast to expectations, personal experiences of CSA were associated with a higher threshold in recognition of CSA incidents. The meaning of the results for prevention and intervention are discussed by highlighting the role of taboos in professional education and the effects of media coverage.

These knives are therefore exposed to high levels of wear and tear, and will also be ofen changed because of loss of material by bad cutting quality. That is why it is interesting to save costs during manufacturing in spite of a correspondingly long service life. This research records the current manufacturing quality of the mower blades and examines how they behave in comparison. Based on the obtained results, further decisions on the methods, procedures and ways of extending the life of the disc mower blades should be proposed. For the investigations, a test bench based on a wear pot was used. The wear that occurs on the blade is determined using several parameters and compared accordingly. The parameters of the test setup determined as a result of the test can be used for further studies of wear resistance. N2 - Bei der Grünfutterernte in der Landwirtschaft werden häufig Scheibenmähwerke eingesetzt, um einen hohen Durchsatz zu erzielen. Die dabei eingesetzten Messer sind einem hohen Verschleiß ausgesetzt und werden häufig wegen Verschleiß gewechselt, was sich in einer schlechten Schnittqualität widerspiegelt. Daher ist es interessant, bereits im Produktionsprozess Kosten einzusparen, ohne dabei die Lebensdauer der Messer zu beeinträchtigen. Diese Studie erfasst die aktuelle Fertigungsqualität von Mähmessern und untersucht, wie sie sich im Vergleich verhalten. Anhand der Ergebnisse sollen weitere Entscheidungen über Methoden, Verfahren und Wege zur Verlängerung der Lebensdauer von Rotorklingen vorgeschlagen werden. Für die Untersuchungen wurde ein Prüfstand auf der Basis des Verschleißtopfverfahrens verwendet. Der am Messer auftretende Verschleiß wird anhand mehrerer Parameter ermittelt und entsprechend verglichen. Die aus den Untersuchungen gewonnenen Parameter können für weiterführende Verschleißuntersuchungen genutzt werden.

These methodologies are seen as crucial to adapt technology design to older people's needs and increase their acceptance of digital technology. Nevertheless, it is often difficult to reach a diverse group of older people, for instance, people with limited technology skills, limited mobility, or cognitive issues. In addition, gerontologists criticized lately how older people's participation unfolds in technology design projects, e.g. that people are pushed into the role of users. Little is known about the motivations and needs of older adults regarding their participation in HCI research. To close this gap, we conducted an online survey (N=46) and semi-structured interviews (N=8) focusing on motivations, willingness and experiences regarding participation. Results show that people are generally willing to participate due to interest in the topic, learning new things and social bonding. However, despite the conceptions within HCI that long-term engagement is crucial within participatory design, older people in the study preferred less commitment and more open formats.

A1 - Steffens, Jochen T1 - The relation between technology acceptance and music listening: An experience sampling study JF - Jahrbuch Musikpsychologie N2 - In the intersection of technology and music listening, understanding user experiences is paramount. This research employed the Experience Sampling Method via the smartphone app MuPsych to continuously capture real-time data on individuals' music listening behaviors and related emotional responses. Over a span of two weeks, participants from Germany were prompted to report on various factors as they engaged in music listening, resulting in a rich dataset. Results indicate that Spotify Premium was the most frequently used music application, with personal playlists being the preferred listening format. To unravel the intricacies of these responses and their determinants, linear mixed-effects model analysis was utilized. Among the critical findings, the Perceived Usefulness and Perceived Ease of Use, two of the central constructs of the Technology Acceptance Model, emerged as significant predictors for the valence and enjoyment of the music experienced by users during the onset of music listening sessions. This highlights the imperative role of user-friendly interfaces in enhancing positive emotional states even before fully engaging with the music, underscoring the need for designers and developers of music-related apps to prioritise usability and useful functions.

Also, the planned AI Act from the European commission defines challenging legal requirements for data quality especially for the market introduction of safety relevant ML systems. In this paper, we introduce a novel approach that supports the data quality assurance process of multiple data quality aspects. This approach enables the verification of quantitative data quality requirements. The concept and benefits are introduced and explained on small example data sets. How the method is applied is demonstrated on the well-known MNIST data set based an handwritten digits.

Durch die Beteiligung möglichst vieler Bürger am politischen Diskurs kann ein neuer inklusiver und vielstimmiger Kommunikationsraum geschaffen werden, in dem die pluralen, vielschichtigen Stimmen der Gesellschaft über die persönlichen Kommunikationsnetzwerke der Einzelnen hinaus in den Austausch treten und so Koorientierung ermöglicht wird. Doch in der Forschung gibt es unterschiedliche Deutungen, ob und inwieweit diese Potenziale eingelöst werden. Der vorliegende Beitrag analysiert basierend auf einer Onlinebefragung die Teilhabe an verschiedenen Formen der Anschlusskommunikation aus einer Milieuperspektive. Die Befunde zeigen, dass die Muster der Anschlusskommunikation sich mit den Ergebnissen der sonstigen Kommunikationspraktiken in den politisch-kommunikativen Milieus decken. Ein politisch selbstbewusstes, engagiertes und informiertes Milieu nutzt besonders die proaktiven Möglichkeiten der Anschlusskommunikation, um Meinungen zu debattieren und auszutauschen. Ein sich in der kommunikativen Teilhabe zurückhaltendes Milieu partizipiert in ebenso geringem Maße an der Anschlusskommunikation und koppelt sich so von einem integrierten Kommunikationsraum ab. Sich abschottende Milieus legen einen starken Fokus auf reaktive Formen der Anschlusskommunikation, die zur permanenten Affirmation eigener Ansichten genutzt werden. Diese unterschiedliche Nutzung trägt dazu bei, dass gesellschaftliche Spaltungstendenzen eher bestärkt statt reduziert werden.
