[{"type":"report","report_number":"409779252","abstract":[{"lang":"ger","text":"In diesem Forschungsprojekt wurde ein Messverfahren zur Bestimmung akustischer Materialparameter von Polymeren im Ultraschallfrequenzbereich entwickelt. Das Verfahrens sollte, die üblichen standardisierten Prüfmethoden erweitern, die bislang primär im quasistatischen oder niederfrequenten Bereich eingesetzt wurden. Im Gegensatz zu bestehenden Verfahren wie dem Zeitstandversuch oder der Dynamisch Mechanischen Analyse (DMA) nach [DIN6721] sollte die neue Methode eine nicht-invasive Charakterisierung der (visko-)elastischen Materialparameter im Frequenzbereich von 0,75 MHz bis 2,5 MHz ermöglichen. Das entwickelte Ultraschallmesssystem arbeitet nach dem Puls Echo-Prinzip und kann eine räumlich segmentierte, ringförmige Anregung erzeugen. Die Bestimmung der frequenzabhängigen Materialparameter geschieht hierbei über ein inverses Verfahren. Die Ergebnisse des Projekts zeigen, dass die Segmentierung der Anregung, die Geometrie der Probe sowie das Puls-Echo-Messprinzip die Messergebnisse sowie die Sensitivität gegenüber Scherparametern wesentlich beeinflussen. Im Rahmen des Projektes wurde auch eine statistische Auswertung des Optimierungsverfahrens hinsichtlich transversal-isotroper Materialsymmetrie mit Rayleigh-Dämpfung durchgeführt. Die Ergebnisse zeigen, dass das entwickelte Verfahren gute Konvergenzeigenschaften aufweist und sich durch verbesserte Robustheit auszeichnet."},{"text":"This research project involved developing a measurement method to determine the acoustic material parameters of polymers within the ultrasonic frequency range. The aim of this method is to extend the range of standardised tests that operate in the quasi-static or low-frequency range. In contrast to existing methods such as the creep test or dynamic mechanical analysis according to [DIN6721], the developed method is capable of non-invasive characterisation of the (visco-)elastic material parameters in the frequency range of 0,75 MHz bis 2,5 MHz. The developed ultrasonic measurement setup utilises the pulse-echo principle and can generate a spatially segmented, ring-shaped excitation. The frequency-dependent material parameters are determined using an inverse method. The final results of the project show that the segmentation of the excitation, the geometry of the specimen and the pulse-echo measurement principle have a significant influence on the measurement results and the sensitivity to shear movements. As part of the project, a statistical evaluation of the optimisation process was also carried out with regard to transversely isotropic material symmetry with Rayleigh damping. The results show that the developed process has good convergence properties and is characterised by improved robustness.","lang":"eng"}],"status":"public","project":[{"_id":"89","name":"Vollständige Bestimmung der akustischen Materialparameter von Polymeren"}],"_id":"65426","user_id":"32616","department":[{"_id":"49"}],"keyword":["Materialcharakterisierung","Polymer","Inverses Problem","Ultraschall","Optimierung"],"language":[{"iso":"ger"}],"publication_status":"published","year":"2026","citation":{"short":"D.

However, optical networks constructed from conventional bulk 2 × 2-beamsplitters encounter inherent scalability issues, as the number of required beamsplitters scales quadratically with the number of optical modes for a fully connected network. Metasurfaces offer a promising route to\r\novercome these constraints. By manipulating light at the wavelength scale, compact optical components with advanced functionalities can be constructed, which address several modes simultaneously. In this work, we design and experimentally utilize a metasurface as a multiport beamsplitter. Furthermore, we realized a multimode interferometer composed of two cascaded metasurfaces. We characterize the individual and cascaded metasurfaces by using classical light, showing controllable splitting ratios through tunable phase relations. We then expand the approach to quantum light, employing single photons to demonstrate second- and third-order photon correlations as well as single photon interference across multiple spatial paths. These results establish metasurface-based multiport beamsplitters as a scalable and reconfigurable platform bridging classical and quantum photonics.

This gives rise to wave-vector-dependent eigenstates of elliptical, linear, and circular polarizations. In particular, fully circular polarization states are not only present at a single point in momentum space (k-space) but also along a line. This circular polarization line, as well as a linear polarization line, emanates from a polarization degeneracy at the Dirac point. We experimentally validate the existence of these eigenstates and demonstrate the energy-, polarization-, and wave vector dependence of this metasurface as well as its sensitivity to fabrication tolerances.

Students’ risk literacy is part of the interdisciplinary research project siMINT (Understanding complex STEM topics: Using simulations to promote competences for the 21st century). One first challenge in this project was to find a common ground for the inconsistently conceptualised terms of risk and risk literacy. Consequently, the aim of this paper is to contribute to the conceptualisation of risk and risk literacy. The first part of this paper provides a literature review on these areas, resulting in a working conceptualisation of the two concepts. We further carried out two consecutive steps of a Delphi study with\r\n                    <jats:italic>N</jats:italic>\r\n                     = 15 and\r\n                    <jats:italic>N</jats:italic>\r\n                     = 12 experts respectively, to develop a common conceptualisation based on the plurality of different dimensions and elements of risk and risk literacy. Based on the results of the first step of the Delphi study, we modified our working conceptualisation, using a common model of risk and risk literacy with different dimensions. In the second step of the Delphi study, the experts comment on (i) the dimensions and (ii) the elements of risk and risk literacy in these dimensions. The results showed that the experts are able to locate their individual definitions of risk in the model with three dimensions (relation between risk/uncertainty, connotation, and mathematical object) that we developed and to formulate reasons for their allocation. Furthermore, the results revealed that risk literacy consists of subsets of mathematical and non-mathematical elements that the experts rate differently with regard to their importance. In general, the results contribute to clarifying the constructs of risk and risk literacy as a basis for developing approaches to improve risk literacy.\r\n                  </jats:p>","lang":"eng"}],"file":[{"date_updated":"2026-04-20T16:20:33Z","date_created":"2026-04-20T16:20:33Z","creator":"binder","file_size":2030179,"file_name":"Eichler Büchter Binder 2026 Conceptualising Risk and Risk Literacy - results of a Delphi Study.pdf","access_level":"closed","file_id":"65468","content_type":"application/pdf","success":1,"relation":"main_file"}],"ddc":["370"],"language":[{"iso":"eng"}],"issue":"1","year":"2026","publisher":"Springer Science and Business Media LLC","date_created":"2026-04-10T05:49:41Z","title":"Conceptualising Risk and Risk Literacy—results of a Delphi Study Konzeptualisierung von Risiko und Risikokompetenz – Ergebnisse einer Delphi-Studie"},{"author":[{"first_name":"Patrick","full_name":"Wiesner, Patrick","last_name":"Wiesner"},{"first_name":"Stefan","full_name":"Krauss, Stefan","last_name":"Krauss"},{"full_name":"Stegmüller, Nathalie","last_name":"Stegmüller","first_name":"Nathalie"},{"first_name":"Karin","full_name":"Binder, Karin","id":"83381","last_name":"Binder"}],"volume":11,"date_updated":"2026-04-20T16:28:13Z","doi":"10.3389/feduc.2026.1741733","publication_status":"published","publication_identifier":{"issn":["2504-284X"]},"has_accepted_license":"1","citation":{"bibtex":"@article{Wiesner_Krauss_Stegmüller_Binder_2026, title={Is flipped classroom really superior?—Questioning the flip in K-12 teaching}, volume={11}, DOI={<a href=\"https://doi.org/10.3389/feduc.2026.1741733\">10.3389/feduc.2026.1741733</a>}, number={1741733}, journal={Frontiers in Education}, publisher={Frontiers Media SA}, author={Wiesner, Patrick and Krauss, Stefan and Stegmüller, Nathalie and Binder, Karin}, year={2026} }","mla":"Wiesner, Patrick, et al. “Is Flipped Classroom Really Superior?—Questioning the Flip in K-12 Teaching.” <i>Frontiers in Education</i>, vol. 11, 1741733, Frontiers Media SA, 2026, doi:<a href=\"https://doi.org/10.3389/feduc.2026.1741733\">10.3389/feduc.2026.1741733</a>.","short":"P.

In the theoretical part of the paper, we shed light on this contradiction by consulting general literature on meta-analyses. Ranking the 50 included FC studies by the number of classes per experimental condition, we found a negative correlation between the “size” of a study and the effect in favor of FC. In the empirical part, we present an FC study with three conditions concerning mathematical teaching, based on\r\n                    <jats:italic>n</jats:italic>\r\n                     = 950 students aged 11–13, in which many relevant covariates (e.g., quality of instruction) were addressed. One FC condition was based on students’ knowledge acquisition through instructional videos at home (FCn:\r\n                    <jats:italic>n</jats:italic>\r\n                     = 12 classes).

Both FC-conditions were experimentally compared with a control group of traditional teaching (TT:\r\n                    <jats:italic>n</jats:italic>\r\n                     = 13 classes). No significant effect on learning gains was found between FCn and TT, indicating that “flipping” alone may not be more effective per se. However, a significant difference was found between FCS and FCn. Thus, supporting students’ self-regulation in addition may in indeed open the door to successful FC, even with very young students.\r\n                  </jats:p>"}]},{"editor":[{"full_name":"Birk, Lisa","last_name":"Birk","first_name":"Lisa"},{"first_name":"Gerrit","last_name":"Loth","full_name":"Loth, Gerrit"},{"orcid":"0009-0003-1440-6466","last_name":"Jotzo","full_name":"Jotzo, Luca","id":"88811","first_name":"Luca"},{"first_name":"Karin","id":"83381","full_name":"Binder, Karin","last_name":"Binder"},{"first_name":"Daniel","full_name":"Frischemeier, Daniel","last_name":"Frischemeier"}],"status":"public","file":[{"date_created":"2026-04-20T16:18:30Z","creator":"binder","date_updated":"2026-04-20T16:18:30Z","access_level":"closed","file_id":"65467","file_name":"Birk, Loth, Jotzo, Binder, Frischemeier 2025 IASE Satellite Editorial.pdf","file_size":1447145,"content_type":"application/pdf","relation":"main_file","success":1}],"type":"conference_editor","ddc":["370"],"file_date_updated":"2026-04-20T16:18:30Z","language":[{"iso":"eng"}],"alternative_title":["Editorial"],"_id":"64797","department":[{"_id":"979"}],"user_id":"83381","year":"2026","citation":{"chicago":"Birk, Lisa, Gerrit Loth, Luca Jotzo, Karin Binder, and Daniel Frischemeier, eds. <i>14th IASE Satellite Conference “Statistics and Data Science Education in STEAM.”</i> International Association for Statistics Education, 2026. <a href=\"https://doi.org/10.52041/iase25.158\">https://doi.org/10.52041/iase25.158</a>.","ieee":"L.

Nearly two decades ago, the service system concept was introduced as a foundational abstraction in service research, drawing on ideas from the service-dominant logic (S-D logic) of marketing. Despite its widespread adoption in service research, particularly in the IS discipline, the service system concept lacks a solid theoretical foundation. This has resulted in conceptual ambiguity and overlap with related constructs, such as service ecosystems. Moreover, it has largely remained a static analytical lens, insufficiently capturing dynamic service phenomena, including value co-creation and co-destruction, as well as the emergence of institutional arrangements. To address these limitations, we propose Luhmann’s systems theory (LST) as a robust framework for conceptualizing service systems as autopoietic (self-creating) systems, in which communication serves as the fundamental mechanism that drives value co-creation. We derive five theoretical propositions from this re-conceptualization that clarify conceptual ambiguity and allow researchers to explore dynamic service phenomena in greater depth. Given LST’s general approach, our conceptualization provides a theoretically grounded, interdisciplinary foundation for advancing service research."}],"publication":"Electronic Markets","language":[{"iso":"eng"}],"keyword":["Service system","Service ecosystem","Systems theory","Service research"],"ddc":["380"],"intvolume":"        36","jel":["L80"],"citation":{"ama":"Beverungen D, Poeppelbuss J, Hemmrich S, Iqbal T.

Reuleaux triangle shaped clinched joints, in particular, show pronounced in-plane anisotropy depending on their orientation. While such effects have been studied at joint and specimen scale, their relevance at the structural level remains largely unexplored. In this work, the influence of joint orientation on the bending response of a joined structure is investigated using numerical simulations. A simplified joint replacement model based on the *CONSTRAINED_SPR2 point-connector formulation in LS-DYNA is employed, with parameters calibrated from previously obtained experimental force displacement data. A hat shaped profile structure subjected to three-point bending is analyzed in a parametric study considering variations in joint orientation, joint spacing, and profile geometry. The results show that joint orientation has little influence during the initial deformation phase but becomes increasingly significant at larger displacements, where joint behavior governs load transfer. Orientation dependent effects are found to influence the global force displacement response and local load redistribution among joints, with magnitudes comparable to those induced by changes in joint spacing and structural geometry. The findings confirm that joint orientation effects remain relevant at the structural level and should be considered in the design of structures assembled using non-rotationally symmetric clinched joints.</jats:p>"}],"status":"public","publication":"Materials Science Forum","type":"conference"},{"language":[{"iso":"ger"}],"user_id":"107378","_id":"65480","status":"public","abstract":[{"lang":"eng","text":"<jats:p>Die Bonner Ethik-Erklärung/Über Künstliche Intelligenzen, Bildung und Subjektwerdung/Tagungsberichte</jats:p>"}],"type":"journal_article","publication":"ZSE (Zeitschrift für Soziologie der Erziehung und Sozialisation)","doi":"10.3262/zse2601101","title":"Erziehungswissenschaftliche Perspektiven auf Familie und ihre Öffentlichkeit(en).

DNA origami in particular provides unique self‐assembly properties, not only enabling a vast variety of functionalization schemes but also presenting a promising route to fabricate large‐scale, bottom‐up nanostructured arrays. This approach has comparable precision to electron beam lithography but avoids slow and expensive patterning steps. However, self‐assembly of lattices with high order and well‐defined periodicity requires careful tuning of the deposition parameters and interactions involved, which has been done mostly on mica so far. As mica is not compatible with standard microfabrication processes, we investigate here the assembly of DNA origami lattices on the most general microfabrication material, that is, silicon wafers, which has turned out to be rather challenging. We study how the forming of polycrystalline 2D‐fishnet‐type lattices is influenced by different incubation conditions and strengths of the origami–origami and origami‐surface interactions, with the aim to create large‐scale single‐crystalline lattices. The lattices are characterized by atomic force microscopy and analyzed for precision of formation, achievable domain size, and surface coverage of well‐formed lattices. Thanks to the silicon substrate, these DNA origami lattices can be further combined with traditional microfabrication processes to turn them, for example, into metamaterials with novel optical properties.</jats:p>"}],"status":"public","_id":"65490","department":[{"_id":"302"}],"user_id":"48864","article_number":"e202500813","language":[{"iso":"eng"}],"publication_identifier":{"issn":["2688-4062","2688-4062"]},"publication_status":"published","issue":"4","year":"2026","intvolume":"         7","citation":{"ieee":"H.
