Accurate wind flow prediction is essential for various applications, including the placement of wind turbines and a multitude of environmental assessments. Traditionally this can be achieved by using time-consuming computational fluid dynamics (CFD) simulations on reanalysis data. This study explores the performance of an autoencoder (AE) and a variational autoencoder (VAE) in approximating downscaled wind speed and direction using real-world reanalysis data and reference geo- and vegetation data. The AE model was trained for 2000 epochs and demonstrates the ability to replicate wind patterns with a mean absolute error (MAE) of approximately −0.9. However, the AE model exhibited a consistent underestimation of wind speeds and a directional shift of approximately 10 degrees compared to CFD reference simulations. The VAE model produced visually improved results, capturing complex wind flow structures more accurately than the AE model. It mainly achieves better local accuracy and a reduced variance of the results. The overall result suggests that while autoencoders can approximate wind flow patterns, challenges remain in capturing the full variability of wind speeds and directions with sufficient precision. The study highlights the importance of balancing reconstruction accuracy and latent space regularization in VAE models. Future work should focus on optimizing model architecture and training strategies to enhance accuracy, prediction reliability and generalizability across diverse wind conditions and various locations.

This paper explores the association of anthropomorphism and cognitive load with respect to the influence of negative attitudes towards robots. The study consists in a cooperative pick-and-place task, where participants are required to repeatedly and alternatingly put a Lego brick onto one of two trays to be picked up and returned by a robot arm. The task is varied by whether or not participants had to remember an 8-digit number inducing extraneous cognitive load (within-subjects factor). Results show significant correlations of some dimensions of anthropomorphism and perceived cognitive load. However, dividing participants in groups with different negative attitudes towards robots, a significant difference of this association is found. This finding puts prior results on the dependency of anthropomorphism of robots and cognitive load into perspective and more research on the underlying cognitive processes is suggested.

Digital communication has played an increasingly important role in schools around the world, especially since the COVID-19 pandemic. For professional communica tion and collaboration in particular, digital tools have provided teachers with the op portunity to collaborate location-independently and to easily exchange information and teaching materials. Hence, this study aimed to explore how teachers communi cate and collaborate digitally by examining differences in the use of instant messag ing and videoconferencing and the attitudes of teachers towards these technologies. Therefore, an online survey was conducted with primary and secondary school teachers from Germany (N = 250, 72.0% female). The analysis showed that mes sengers were used significantly more than videoconferences and that they differed in their usefulness for occasions of communication and collaboration. Structural equation modeling indicated that the self-assessed digital communication compe tence of teachers is both a significant predictor for the behavioral intention to use messengers as well as videoconferences, although the behavioral intention to use messengers in the future was significantly higher than for videoconferences. While a higher threshold to use videoconferences might be a reason for the differences that were identified in this study, further research into the communication and col laboration among teachers is still needed to understand the reasons for the differ ences in use.

Mit der Einführung des Promotionsrechts an bayerischen Hochschulen für angewandte Wissenschaften widmen sich diese fortan auch der Ausbildung von Promovierenden. Im Gegensatz zu Universitäten ist jedoch eine hochwertige didaktische Qualifikation der Promovierenden bayerischer Hochschulen gegenwärtig noch nicht etabliert. Um diesem Bedarf gerecht zu werden, wurde an der Hochschule Ansbach ein Modul zu digital-analoger Hochschullehre namens »Teaching Skills« für Promovierende entwickelt und im Wintersemester 2023/24 erprobt und evaluiert. In diesem Beitrag wird zunächst der interaktive didaktische Ansatz des Lehrkonzepts erörtert und aufgezeigt, wie die einzelnen Lehreinheiten konzeptioniert wurden. Anschließend folgt ein Einblick in die konkrete Implementierung des Moduls an der Hochschule Ansbach. Abschließend erwachsen aus Begleitevaluation, den Beobachtungen des Projektteams, sowie den Lessons Learned Empfehlungen für die erfolgreiche Implementierung des Konzepts an weiteren Hochschulen.

The study examines sustainable tourism behaviour at the historic city of Rothenburg ob der Tauber. The research aims to explain tourists' sustainable behaviour and to uncover configurations that lead to sustainable or unsustainable behaviour. The present study is based on the Theory of Planned Behaviour (TPB) as its theoretical framework. A mixed-method design is then employed, integrating quantitative and qualitative research methodologies. The quantitative arm of the study employs regression analysis, while the qualitative research uses the fuzzy-set Qualitative Comparative Analysis (fsQCA).
The findings from the regression analysis revealed that sustainability-oriented attitudes, social norms, and behavioural control have a statistically significant impact on tourists' sustainability-oriented behavioural intention, in descending order of importance. The fsQCA results showed that strong attitudes are a necessary condition for strong behavioural intention toward sustainable tourism activities. Weak social norms are an essential condition for weak behavioural intention toward sustainable tourism activities. Furthermore, the study identified the following sufficient conditions for a strong intention to engage in sustainable tourism activities: strong social norms paired with weak behavioural control, or strong attitudes in conjunction with strong social norms.

Printing of polymer parts via digital light processing (DLP) is an established technology to produce functional complex parts within a short period of time. Within recent years this technology has advanced in even higher geometrical accuracy of the parts since printers and materials were constantly improved. Nowadays, it is possible to print parts with features in micro- (µm) or even nanoscale (nm), opening new fields of application and further improvement to already existing parts. Similar to stereolithography (SLA), DLP applies UV light to harden a photopolymer resin in a layer-by-layer process. This enables printing parts with complex geometries such as cavities, implying the resin can later exit the part. However, DLP has an advantage over other 3D-printing technologies when it comes to creating cavities or the printing of overhang structures in general. Since in DLP the entire layer is hardened at once, less support structure is needed to achieve a uniform, stable layer. In consequence, this opens the design option to print micro cavities without any support structures needed. This paper highlights the process of micro DLP printing of polymer parts, focusing on the influence of the most relevant parameters on the successful print of overhang structures. Therefore, the paper presents an experimental analysis, investigating the effects of relevant printing parameters of an overhang on the dimensional accuracy of the resulting parts. The results show a significant dependence of the bridges (overhangs) on gaps size and curing time, and the deformation of the bridges are in the opposite sides of the parts.

The aim of this study was to investigate whether and to what extent competitiveness influences the overall outcome of a firm. With in this context resource based view and Porter's diamond model were revisited and examined more closely. Based on a review of the longstanding research on competitiveness, the results highlight that there are several internal and external factors that have an impact on the competitiveness of a firm. While the overall aim was to provide a review of the existing literature on the topic from the historical perspective, the study proposes a conceptual framework including the key determinants for achieving greater international competitiveness for the firms. This study emphasizes the transformative potential of firm's competitiveness, not only for success but also for competing in international markets. In addition, this study aims to stimulate further research into the new and emerging trends that can impact firms' competitiveness.

This study explores a resource-based perspective on subjective wellbeing in educational contexts by introducing the concept of happiness capital. Building on the educational and learning capital approach, we adapted existing measures to assess how personal and environmental resources contribute to students’ wellbeing. In a sample of 1,528 Egyptian secondary school students, perceived happiness capital significantly predicted life satisfaction, positive and negative emotions across all age groups. These findings suggest that the same resource structures supporting learning can foster emotional flourishing. We briefly discuss implications for resource-based models of wellbeing in education and propose directions for future research.

 

• Vor dem Hintergrund sinkender Studierendenzahlen und des Fachkräftemangels in den technischen Berufen in Deutschland, rekrutieren die Hochschulen in Bayern zunehmend Studierende aus dem Ausland. Dabei stoßen die angebotenen internationalen Studiengänge besonders bei Studierenden aus Indien auf großes Interesse. Andersartige Kompetenzprofile aus dem außereuropäischen Bachelorstudium in Kombination mit sehr hohen Erwartungen der Studierenden an ein Masterstudium in Deutschland führen zu enormen Herausforderungen bei allen Beteiligten. Förderlich für den erfolgreichen Studienverlauf ist es, Maßnahmen zur Gruppendurchmischung zwischen ausländischen und deutschen Studierenden wie internationale Postersessions und gemeinsame Studienangebote zu implementieren. Darüber hinaus ist es erforderlich, Regeln der guten wissenschaftlichen Praxis klar zu kommunizieren und deren Befolgung einzufordern. Nicht zuletzt ist die Stärkung der Sprachkompetenz ein Schlüssel für ein erfolgreiches Studium.

Sport-tracking applications can enhance physical activity but may also induce stress through social comparison. This study examines how social comparison features influence user experience (UX), focusing on motivation, stress, and mental well-being. A survey of 101 German sport-tracking app users assessed intrinsic and extrinsic motivation, perceived stress, self-efficacy, enjoyment, social comparison orientation, and UX. Results reveal that higher social comparison consistently lowers intrinsic motivation, raises extrinsic motivation, and increases stress levels, while positive UX boosts intrinsic motivation and enjoyment and indirectly buffers stress. Notably, app designs prioritizing mastery and personal progress over competitive rankings foster autonomy, competence, and relatedness, supporting mental health and long-term adherence. These findings highlight the ambivalent effects of social features and underscore the need for sport-tracking apps to minimize harmful comparisons and promote self-determined motivation through supportive, user-friendly features. Practical implications include designing for sustainable engagement and well-being rather than exclusive competition.
