Slender constituents are present in many structures and materials. In associated mechanical models, each slender constituent is often described with a beam. Contact between beams is essential to incorporate in mechanical models, but associated contact frameworks are only demonstrated to work for beams with circular cross-sections. Only two studies have shown the ability to treat contact between beams with elliptical cross-sections, but those frameworks are limited to point-wise contact, which narrows their applicability. This contribution presents initial results of a framework for shear-deformable beams with elliptical cross-sections if contact occurs along a line or at an area (instead of at a point). This is achieved by integrating a penalty potential over one of the beams’ surfaces. Simo-Reissner Geometrically Exact Beam (GEB) elements are employed to discretise each beam. As the surface of an assembly of such beam elements is discontinuous, a smoothed surface is introduced to formulate the contact kinematics. This enables the treatment of contact for large sliding displacements and substantial deformations. [less ▲]

Dieses Kapitel geht der Frage nach, ob Lehrerüberzeugungen und –erwartungen, je nach sonderpädagogischem Förderbedarf variieren. Außerdem wurde deren Einfluss sowohl auf die Gefühle bei Auseinandersetzung mit der Inklusion von unterschiedlichen Schüler*innen, als auch auf die persönliche Bereitschaft Inklusion umzusetzen, untersucht. Die Studien basieren einerseits auf dem Dualen Prozessmodel der sozialen Kognition und betrachten andererseits das Stereotype-Content-Modell, laut dem Wärme und Kompetenz über 80% der Unterschiedlichkeiten in der Personenwahrnehmung erklären. Die Ergebnisse zeigten, dass Überzeugungen und Erwartungen von dem Typ von Förderbedarf beeinflusst werden. Positivere Überzeugungen bezüglich der Schülermerkmale (Wärme und Kompetenz) und höhere Leistungserwartungen waren hierbei mit positiveren Gefühlen und einer stärker ausgeprägten persönlichen Bereitschaft, die Schüler*innen mit sonderpädagogischem Förderbedarf zu inkludieren, verbunden. Abschließend werden die daraus resultierenden Konsequenzen für die Lehreraus- und -weiterbildung abgeleitet und diskutiert. [less ▲]

In verschiedenen europäischen Ländern führt der Wechsel zur Sekundarschule zu einer bedeutsamen Aufgliederung der Bildungswege, welche ein unterschiedlich hohes Schulleistungsniveau der Schüler*innen voraussetzen. Die Akkuratheit der Zuweisung von Sekundarschulformen bestimmt nicht nur die Optionen der Schüler*innen bei späteren Übergangen im Bildungssystem, sondern beeinflusst auch den weiteren beruflichen und persönlichen Werdegang der Schüler*innen. Schüler*innen mit Migrationshintergrund sind auf die höheren sekundären Schulformen unterrepräsentiert. Inwiefern diese Unterrepräsentation auf stereotypgeprägte Leistungserwartungen zurückzuführen ist, ist bis jetzt unklar, denn es lisgt kein Kriterium vor, um die Urteilsakkuratheit adäquat zu messen. In diesem Kapitel wird ein Ansatz beschrieben, ein solches Akkuratheitskriterium zu entwickeln und zu validieren. In einem zweiten Schritt wird das Kriterium angewendet, um den Zusammenhang zwischen stereotypgeprägten Erwartungen und der Akkuratheit der Übergangsentscheidungen zu untersuchen. Das Kriterium erweist sich als valides Maß und könnte so einen wertvollen Ansatz für weitere Untersuchungen der Akkuratheit von Lehrerurteilen darstellen. Obwohl Lehrer*innen im Allgemeinen eine hohe Urteilsakkuratheit aufweisen, bestätigen die Befunde dennoch die Zusammenhänge zwischen stereotypgeprägten Erwartungen und Urteilsverzerrungen. [less ▲]

This paper concerns the reusable components and recycled materials from demounted structures 16 which may draw a large amount of waste in construction industry. By a series of literature review 17 and analyses, a material and component bank was proposed to manage more effectively the 18 recycling of materials and direct reuse of components even of whole components obtained from 19 old structures to facilitate a more sustainable construction industry. The concept, main businesses 20 and work operation of the bank were illustrated in detail including its potential management 21 method and supply chain. The relationship between the bank and current building information 22 modelling, design for deconstruction, supply chain and life cycle assessment based on the bank 23 were then analysed in detail. It can be concluded that the bank could pave the way for effectively 24 performing a further and repaid reuse of components and perfecting current recycling of materials 25 to contribute a more sustainable built environment from the view of various terms mentioned in 26 this study. The bank also can link with current method of life cycle assessment or environmental 27 impact assessment well, which all can promote the construction sustainability indicating the bank 28 can be integrated into current construction industry easily for the future.

Task orientation is currently a prominent concept under discussion in primary school di-dactics. It focuses on tasks along which pupils acquire competences on distinct levels of compe-tence. The qualitative empirical study ANONYMOUS pursues the question which conception of task orientation is present in current textbooks in primary science education. The study follows two foci: (i) the introduction of a new category system for the analysis of the task-orientation potential of tasks, based on the further development of existing category systems for analyzing tasks; and (ii) the analysis of 994 task statements in science textbooks with respect to the di-dactic quality of their task orientation. The sample included nine primary science textbooks, four from Germany and five from Luxembourg. Textbooks were selected from the most fre-quently sold series in the respective country. All tasks of the textbooks were analyzed deduc-tively and inductively by four coders in three steps: (i) identifying tasks with task-oriented po-tential; (ii) itemizing different types of task-orientation potential; and (iii) comparing the text-books with respect to country- and period-specific manifestations of task orientation. Analysis indicated that (i) there are few tasks which meet the criteria of task orientation; (ii) distinct types of task orientation can be generated, among which implicit forms dominate; and (iii) dif-ferences occur in the characteristics of task orientation between older and newer textbooks as well as between German and Luxembourgish ones. Central points of discussion ensue from this: the need to develop models for social and cognitive activation for tasks, challenges for school management and professional development for teachers, and support for pupils—in particular high achieving heterogenization.

Early life adversity (ELA) may cause permanent disturbances in brain-body signaling. These disturbances are thought to contribute to physical symptoms and emotional dysregulation in adulthood. The current study investigated the effects of childhood trauma on young adults’ interoceptive accuracy as an indicator of brain-body communication that may be dysregulated by ELA. Sixty-six participants completed an online-questionnaire followed by a laboratory session including the socially-evaluated cold pressor stress test during which ECG, salivary cortisol and interoceptive accuracy were assessed. Childhood trauma was negatively related to interoceptive accuracy (IAc) after the stressor. This stress-effect could not be observed for heart rate and cortisol, which were unrelated to IAc. Participants reporting higher baseline unpleasantness exhibited lower IAc after the stressor, while increases in unpleasantness due to the stressor were associated with higher IAc. Unpleasantness at baseline mediated the effect of childhood trauma on IAc after the stressor. [less ▲]

This paper proposes BODYFITR, a fully automatic method to fit a human body model to static 3D scans with complex poses. Automatic and reliable 3D human body fitting is necessary for many applications related to healthcare, digital ergonomics, avatar creation and security, especially in industrial contexts for large-scale product design. Existing works either make prior assumptions on the pose, require manual annotation of the data or have difficulty handling complex poses. This work addresses these limitations by providing a novel automatic fitting pipeline with carefully integrated building blocks designed for a systematic and robust approach. It is validated on the 3DBodyTex dataset, with hundreds of high-quality 3D body scans, and shown to outperform prior works in static body pose and shape estimation, qualitatively and quantitatively. The method is also applied to the creation of realistic 3D avatars from the high-quality texture scans of 3DBodyTex, further demonstrating its capabilities. [less ▲]
