Here, we combine these requirements in a scheme for OCT measurements with undetected photons based on nonlinear Ti : Li Nb O 3 waveguides. We investigate the performance benchmarks of the commonly used SU(1,1) scheme in comparison to an induced-coherence scheme and find that the latter is actually better suited when implementing measurements with undetected photons in integrated systems.

To do so, we reveal empirical results from the application of video recall in three interdisciplinary research projects that applied the method for the qualitative and quantitative assessment of cognitive and behavioral phenomena in everyday explanations. In all three projects, video recall was applied as a post-hoc procedure following the recording of dyadic face-to-face explanations of board games. The design of the video recall procedure differed between individual projects because they pursued different research objectives – that is the investigation of (1) an interlocutor's multimodal signals of understanding, (2) the change in assumptions about an interlocutor's dispositional and situational knowledge, and (3) the differentiated assessment of an interlocutor's developing understanding of domain knowledge aspects by distinguishing between mechanistic and functional explanatory stances. By discussing the benefits and the limitations of each procedure, this article provides critical reflections on video recall as a versatile research method applied for the analysis of human multimodal behavior in interaction and cognitive processing.}}, author = {{Lazarov, Stefan Teodorov and Schaffer, Michael and Gladow, Viviane and Buschmeier, Hendrik and Buhl, Heike M. and Grimminger, Angela}}, pages = {{29}}, title = {{{Retrospective video recall for analyzing cognitive processes in naturalistic explanations}}}, year = {{2026}}, } @article{65181, abstract = {{In many Western societies, mass immigration has been one of the most divisive policy issues in recent years. Seemingly moderate inflows of migrants can have substantial demographic consequences in the long run, due to (1) higher fertility of the migrant population, (2) its younger age distribution, and (3) the possibility of family reunification. Yet, demography hardly appears in the policy debate, even in media outlets that are critical of mass immigration. This may indicate that the mechanics of population dynamics are not widely understood. We design a laboratory experiment in which we confront subjects with 30 different migration scenarios. Subjects have to decide when to stop a given inflow of migrants to achieve a target share of migrants after 60 years. In line with all our pre-registered hypotheses, in scenarios that contain elements of usual mass immigration the growth of the migrant population is systematically underestimated. This bias is even stronger in scenarios that closely resemble the German situation since the opening of the borders during the 2015 refugee crisis.}}, author = {{Abbink, Klaus and Mir Djawadi, Behnud}}, journal = {{SSRN Electronic Journal}}, publisher = {{Elsevier BV}}, title = {{{Migration and Long-Term Demographic Change: Can We Control the Numbers?}}}, doi = {{http://dx.doi.org/10.2139/ssrn.6343618}}, year = {{2026}}, } @article{64863, abstract = {{Traditional dyadic customer-provider interactions are being shifted to polyadic interactions involving diverse participants in digital service ecosystems.

While existing literature examines human-to-human interactions, knowledge of service interactions between human actors and AI-based systems is still underexplored. To address this research gap, we develop a taxonomy, comprising six iterations, that explores the peculiarities of AI as either a resource or a (non-human) agent in digital service ecosystems. We evaluate our taxonomy using a multiple case study and derive the four archetypes of AI in digital service ecosystems: (1) discriminative experience enhancer, (2) protective ecosystem orchestrator, (3) ecosystem innovation companion, and (4) personalized service composer. Our results extend the knowledge on service science by showing how AI-based systems—discriminative or generative, and focusing on the interaction in the ecosystem or the individual service encounter—assume the role of resources and non-human agents.

To achieve their maximum mechanical properties, the fiber-matrix adhesion (FMA) is critical. In this work, continuous fiber-reinforced thermoplastic laminates (CFRTPL) with a polypropylene (PP) matrix and twill woven glass fiber fabrics are produced by film stacking. The films used contain different amounts of maleic-anhydride-grafted PP (MA-g-PP) as a coupling agent to produce CFRTPL of different mechanical strengths. To analyze the FMA, the CFRTPL are subjected to Charpy-impact and tensile tests. Additionally, single fiber pull-out tests (SFPT) are conducted to further investigate the effect of MA-g-PP on the FMA. The results of the SFPT show an improvement in apparent interfacial shear strength (AIFSS) when the MA-g-PP content is increased, which can be attributed to an increase in FMA. However, the research shows that MA-g-PP has a low impact on the mechanical properties if the force is applied parallel to the warp and weft threads during tensile testing and the results of the Charpy-impact testing suffer from embrittlement of the matrix material. Subsequently, the results of this study are compared to three-point flexural tests conducted in a previous study. It can be concluded that tensile and impact tests are not suited to investigate FMA on a macroscopic scale, while SFPT and flexural tests provide a better alternative.}}, author = {{Moritzer, Elmar and Brandes, Philipp and Wittler, Maurice and Claes, Leander and Wippermann, Mareen and Haag, Markus and Gries, Thomas and Henning, Bernd}}, issn = {{0930-777X}}, journal = {{International Polymer Processing}}, publisher = {{Walter de Gruyter GmbH}}, title = {{{Fiber-matrix adhesion in glass fiber reinforced thermoplastic composite laminates and its effect on mechanical properties}}}, doi = {{10.1515/ipp-2025-0077}}, year = {{2026}}, } @article{65253, author = {{Abdelwanis, Ali Hassan Ali and Haucke-Korber, Barnabas and Jakobeit, Darius and Kirchgässner, Wilhelm and Meyer, Marvin and Schenke, Maximilian and Vater, Hendrik and Wallscheid, Oliver and Weber, Daniel}}, issn = {{2577-3569}}, journal = {{Journal of Open Source Education}}, number = {{97}}, publisher = {{The Open Journal}}, title = {{{Reinforcement Learning: A Comprehensive Open-Source Course}}}, doi = {{10.21105/jose.00306}}, volume = {{9}}, year = {{2026}}, } @inbook{65168, author = {{Keuchen, Marion and Lindemeyer, Sabine}}, booktitle = {{Seelsorge im Lebensraum Schule.

Empirical studies demonstrate that while #fitspiration holds the potential to motivate adolescents to be physically active, it also perpetuates gender-stereotyped, predominantly White, ableist, and normative body ideals associated with fitness and an idealized weight. This trend can be linked to an increased risk of body image concerns or disordered eating among adolescents. Understanding adolescents’ engagement with fitspiration content is crucial for tailoring health and media literacy education within physical education. Therefore, a systematic review of qualitative and quantitative studies was conducted. A search of five electronic databases yielded 312 abstracts, of which 12 met the inclusion criteria. The analysis of the selected studies was based on thematic analysis and included both primary and secondary data. Seven analytical themes emerged: (1) 37–56% of adolescents actively engage with fitspiration content on social media; (2) it fulfills their need for informal and accessible participation; (3) it fosters a sense of social connection; (4) they derive inspiration from peers and influencers; (5) they aspire to idealized body standards; (6) they seek quick solutions when dissatisfied with their bodies; and (7) a few become demotivated and critical when unable to achieve these ideals. Consequently, educators should balance the potential benefits with media literacy interventions to mitigate risks such as body image issues and eating disorders.}}, author = {{Grimminger-Seidensticker, Elke and Korte, Johanna}}, issn = {{2509-3142}}, journal = {{German Journal of Exercise and Sport Research}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Adolescents’ engagement with #fitspiration content—a systematic review of qualitative and quantitative studies and pedagogical implications for physical education Der Umgang von Jugendlichen mit Inhalten zu #fitspiration - Ein systematisches Review qualitativer und quantitativer Studien sowie pädagogische Implikationen für den Sportunterricht}}}, doi = {{10.1007/s12662-026-01107-7}}, year = {{2026}}, }
