Finding the required information to succeed in the organisation of everyday study life is not always easy for a student. Ontologies are an instrument to define a domain by illustrating its concepts and thereby presenting knowledge in a structured way. In this paper, our aim is to design an ontology that is suitable for the higher education environment of a German university to build a Knowledge Graph for a conversational AI. As a research context, the Ansbach University of Applied Science is used. The paper is organised into five sections. After a brief introduction in Section 1, Section 2 reviews previous work of conducted ontologies within the higher education environment, whereas Section 3 outlines the methodology for developing the ontology and presents the final result. The development procedure is thereby partly based on the ontology framework provided by Stanford University (Noy & McGuinness, 2001). The presented ontology, which delivers possible classes for the development, and transferability to other universities will then be discussed in Section 4. Finally, the conclusion and approaches for future work with ensuring a constant up-to-dateness of the classes are given in Section 5.

Tourism recommendation systems can mitigate the potential impact of choice overload on tourists. Social robots are a promising approach to provide recommendations to tourists through an engaging and intuitive user interface on sites like tourist information offices. This study investigates whether tourists perceive tourism recommendations provided via social robots as a satisfying and effective experience and whether tourists respond better to a more human or robotic design of social robot interactions. Therefore, an experiment is conducted at a real-world tourist information office where 60 tourists are exposed to either the more human or robotic version of the social robot recommender system. Their feedback is collected with a survey. The results show that the social robot is perceived positively across
all user-centric evaluation dimensions. This indicates that tourists accept social robots in real-world tourist recommendation situations and would also use them in the future.

The current energy crisis and the high cost of fossil fuels pose major challenges for energy-intensive industries such as the non-ferrous foundry industry. Therefore, it is important to promote the transition to renewable energy sources with the help of the electrification of the melting units. In this pilot study, for the first time the conversion of conventional foundries to sustainable technologies is simulated. For this purpose, a simulation model is developed based on a selected example company. It considers the energy consumption and the logistical effects of a converted operation. The simulation model is implemented as a hybrid simulation combining a discrete
event simulation at the plant level and a process simulation within the furnaces. The study shows how a sustainable energy supply can be achieved in foundries. It also considers the impact of efficiency, energy costs and emissions.

Sexist content is widespread on social media and can reduce women's psychological well-being and their willingness to participate in online discourse, making it a societal issue. To counter these effects, social media platforms employ moderators. To date, little is known about the effectiveness of different forms of moderation in creating a safe space and their acceptance, in particular from the perspective of women as members of the targeted group and users in general (rather than perpetrators). In this research, we propose that some common forms of moderation can be systematized along two facets of visibility, namely visibility of sexist content and of counterspeech. In an online experiment (N = 839), we manipulated these two facets and tested how they shaped social norms, feelings of safety, and intent to participate, as well as fairness, trustworthiness, and efficacy evaluations. In line with our predictions, deletion of sexist content - i.e., its invisibility - and (public) counterspeech - i.e., its visibility - against visible sexist content contributed to creating a safe space. Looking at the underlying psychological mechanism, we found that these effects were largely driven by changes in what was perceived normative in the presented context. Interestingly, deletion of sexist content was judged as less fair than counterspeech against visible sexist content. Our research contributes to a growing body of literature that highlights the importance of norms in creating safer online environments and provides practical implications for moderators for selecting actions that can be effective and accepted.

Impulsbeitrag zur Entrepreneurship CRUISE (Oktober 2023)

Dieser Beitrag befasst sich mit der grundlegenden Beziehung und Bedeutung von Bildung, Intuition und Kreativität als entscheidende Triebkräfte für Innovationen und Entrepreneurship. In diesem Zusammenhang stellen sich die zentralen Fragen, was unter Bildung zu verstehen ist und welche kreativen Rollen Bildung und Intuition bei der Entstehung von Neuem spielen.

Der moderne Bildungsbegriff entwickelte sich im Wesentlichen aus den Ideen des Humanismus und der Aufklärung, die ihre Wurzeln in der Antike haben. Im heutigen Verständnis wird Bildung zu einer kontinuierlichen Anpassung und Entwicklung. Der Mensch ist ein dynamisches Wesen, das sowohl von der jeweiligen Umwelt beeinflusst wird, als auch selbst diese Umwelt verändern und beeinflussen kann. Bildung erzeugt und vermittelt lebenslanges Wissen. Für die Wahrnehmung und Beurteilung unserer Umwelt und des Lebens gibt es neben der Rationalität auch eine Welt der Gefühle, Emotionen und des Herzens.

In Anlehnung an das Wahrnehmungs- und Urteilsmodell von Carl Gustav Jung werden Intuition und insbesondere die intuitive Kompetenz als zentrale Einflussfaktoren von Bildung und Kreativität angesprochen. Intuitive Wahrnehmung öffnet uns den Zugang zu neuem Wissen und eröffnet ein vielschichtiges Spektrum an Kreativität. Als Motor der Innovation wird Bildung zum Bindeglied zwischen bewusster Rationalität und unbewusster Emotionalität.

Am Ende des Beitrages steht eine kritische Würdigung der innovativen Möglichkeiten des Menschen. Es ist zugleich eine Ermahnung zu einem bewahrenden und integrativen Schaffen aus ethischer Sicht. Unsere schöpferische Kraft gibt uns kreatives Potential und befähigt uns, die Welt immer wieder zu verändern und zu gestalten.

Epoxy resins are widely used polymers in the automotive and aerospace fields. Different blends of novel biodegradable resins have been studied in the last years in order to provide sustainability while maintaining the same properties of epoxy resins. Bio-based thermoset resins made with acrylated epoxidized soybean oil are well-studied in different vat polymerization techniques. The present work compares a bio-based resin and a petroleum-based resin. A benchmark with different features was designed and manufactured by a VAT photopolymerization process using both materials; measured with an optical scanning device; thus, the dimensional deviations were analyzed through inspection software. Tensile and flexural specimens were manufactured with the same procedure and tested with a dynamometer machine. Therefore, the comparison between a biodegradable resin and a petroleum-based resin is discussed in terms of the quality and mechanical performances of manufactured parts, considering the use of identical printing conditions. Some parts are required to satisfy both the requirements at the same time, such as the gears. Therefore, dimensional accuracy and mechanical strength need to be controlled and evaluated in a unique final quantification. This work proposes a novelty performance index to quantify dimensional accuracy and mechanical strength simultaneously. By combining the two aspects it is possible to define the overall performance obtained with the used material, optimizing the manufacturing process by choosing the proper material for each purpose.
