It investigates a didactic design that was implemented in six schools and was empirically researched utilizing si-tuational analysis. Based on tensions, that emerge due to conflicting expectations, it can be shown, that the teacher's role extends beyond the dichotomy of directive instruction versus open facilitation. Instead, it encompasses an interplay of six divergent roles which are discussed in their positions in relation to each other. These considerations enrich the understanding of teaching practices in popular music education, emphasizing the redefinition of teacher-student relationships for song-writing in school music.","lang":"eng"}],"publication":"46.

A single case situational analysis reveals how standardized instrumental and music production practices are combined to form a hybrid practice. It shows that traditional music education institutions, such as music schools and conservatories, specialize in the selection of chord tones, while You-Tube videos focus on sound design. Using an actor-network theory approach, the study demonstrates the permeability of informal and institutional learning spaces.

This is partly due to missing powerful lead-free piezoelectric ceramic parts in the commercial market. There has been much research on lead-free materials but developing them into marketable parts seems to be an ongoing process. The actual exemption of ROHS has expired, but as the new exemption has already been requested, ceramic suppliers keep on selling lead containing products. Nevertheless, these should be replaced by lead-free alternatives for environmental and health issues. \r\nThis contribution focuses on exploring the technological readiness level of lead-free hard piezoceramics for prestressed ultrasonic transducers. A small series of bolted Langevin transducers was set up with standard PZT material and three commercial lead-free variants. Results of the building process from individual ring ceramic characteristics to transducer load tests are presented. The main finding of this study is that the lead-free materials technically can compete with the standard PZT for medium-power applications. Some adaptations in the ultrasonic system must be done: the geometry must be altered to fit resonance frequency, and higher voltages or thinner ceramics are needed to achieve the same vibration level at low load. For reaching same power, the volume of lead-free ceramics must be 1.5 to 3 times larger. As already promoted in literature, mechanical losses at high vibration levels are smaller for the lead-free materials. This might help to argument lead-free piezoelectric materials in some applications.\r\n\r\nReferences\r\n1.\tDirective 2011/65/EU of the European Parliament and of the Council of 8 June 2011 on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment.

At the beginning of the 1950s, the first ultrasonic cleaning devices finally came onto the market. Today, the range of applications ranges from household appliances for jewellery and eyewear cleaning to classic cleaning baths for metal parts and systems for cleaning highly sensitive electronic components. There is a certain gap in handheld, mobile cleaning equipment. Although devices for spot cleaning of textiles are known, the cleaning effect is usually low. \r\nDue to the directive 2011/65/EU on the restriction of the use of hazardous substances in electrical and electronic equipment (RoHS) [1] lead should no longer be used in technical devices. As today’s standard ceramics for medium and high-power ultrasonic transducers typically contain lead, there is a need to explore the use of lead-free ceramics in this field. Honda [2] already offers a cleaning transducer based on lead-free piezoelectric ceramics, but it is designed to be used in cleaning baths.\r\nThis article presents the model-based development of a highly innovative ultrasonic cleaner. On the one hand, lead-free piezoelectric ceramics are used, and on the other hand, a special sonotrode has been developed that concentrates the sound in such a way that a strong cavitation and thus cleaning effect is achieved with comparatively low power in a short time. Coupled field finite element method was used to find an appropriate geometry for the focussing sonotrode. The comparison of simulation and measurement results shows that the lead-free piezoceramics used do their job well and can keep up with standard ceramics, but more ceramic volume is needed to achieve same power. An advanced control concept was elaborated to ensure continuous hard cavitation at varying distances between the sonotrode and the part to be cleaned. Cleaning results for different surfaces and contaminations are presented. The concept of the focusing sonotrode shows that a convincing cleaning result can be achieved even with low power and in short time, provided that the oscillation system and control electronics are suitably coordinated.\r\n\r\nReferences\r\n[1] http://data.europa.eu/eli/dir/2011/65/2024-08-01 \r\n[2] https://en.honda-el.co.jp/product/ceramics/lineup/lead_off/lead-off \r\n"}],"date_created":"2026-03-02T10:47:48Z","file":[{"creator":"hemsel","date_created":"2026-03-02T10:46:43Z","file_size":1946202,"access_level":"open_access","file_name":"ICU_2025_Hemsel.pdf","date_updated":"2026-03-02T10:58:37Z","relation":"main_file","content_type":"application/pdf","file_id":"64801"}],"department":[{"_id":"151"}],"oa":"1","type":"conference"},{"date_updated":"2026-03-02T10:59:53Z","has_accepted_license":"1","title":"Time dependent material characteristics of prestressed piezoelectric ceramics in langevin transducers","status":"public","year":"2025","conference":{"end_date":"2025-07-3","start_date":"2025-07-1","name":"22nd International Workshop on Piezoelectric Materials and Applications in Actuators (IWPMA)","location":"Vilnius, Lithuania"},"author":[{"full_name":"Scheidemann, Claus","last_name":"Scheidemann","first_name":"Claus","id":"38259"},{"full_name":"Hemsel, Tobias","last_name":"Hemsel","first_name":"Tobias","id":"210"},{"full_name":"Sextro, Walter","first_name":"Walter","last_name":"Sextro","id":"21220"}],"ddc":["620"],"user_id":"210","_id":"61755","language":[{"iso":"eng"}],"project":[{"name":"FOR 5208: Modellbasierte Bestimmung nichtlinearer Eigenschaften von Piezokeramiken für Leistungsschallanwendungen (NEPTUN)","_id":"245"}],"file_date_updated":"2026-03-02T10:59:53Z","citation":{"chicago":"Scheidemann, Claus, Tobias Hemsel, and Walter Sextro. “Time Dependent Material Characteristics of Prestressed Piezoelectric Ceramics in Langevin Transducers,” 2025.","short":"C.

Vor diesem Hintergrund untersucht das vorliegende Paper die Rolle der Kreislaufwirtschaft als wegweisendes Wirtschaftsmodell, das von der Europäischen Union gefördert wird. Ziel der Kreislaufwirtschaft ist es, den Ressourcenverbrauch und die Abfallproduktion zu minimieren, indem ein kontinuierlicher Kreislauf aus Nutzung, Wiederverwendung und Recycling von Materialien geschaffen wird. \r\nEin zentraler Aspekt dabei ist der Produktentwicklungsprozess (PEP) - ein vielschichtiger Prozess mit zahlreichen Einflussfaktoren und theoretisch unbegrenzten Gestaltungsmöglichkeiten. Diese Vielfalt führt jedoch zu erheblichen Entscheidungsunsicherheiten, die die Umsetzung von Kreislaufwirtschaftsprinzipien erschweren können. Um diese Herausforderungen zu adressieren, wird ein methodischer Prozess vorgestellt, der eine systematische Klassifizierung im Zusammenhang mit umliegenden Bauteilen ermöglicht. Die Methodik basiert auf einer strukturierten Bewertung von Bauteilen hinsichtlich ihrer Relevanz für die Kreislaufwirtschaft. Dabei werden zentrale Aspekte wie Wiederverwendbarkeit, Recyclingfähigkeit und Ressourceneffizienz berücksichtigt, darunter: \r\n•\tHandelt es sich um ein Gebrauchs- oder Verbrauchsprodukt?\r\n•\tIst das Bauteil eine Wiederverwendung oder eine Neufertigung?\r\n•\tIst das Bauteil standardisiert, zugekauft oder individuell ausgerichtet?\r\n•\tWelche primäre Funktion nimmt das Bauteil ein?\r\nDiese strukturierte Klassifizierung unterstützt die Entscheidungsfindung bereits früh im PEP. Sie ermöglicht es Produktentwickelnden, Potenziale für die Kreislaufwirtschaft frühzeitig zu erkennen und gezielt nachhaltige Maßnahmen zu ergreifen.\r\nDie entwickelte Methodik bildet somit eine Grundlage für die Integration kreislaufwirtschaftlicher Prinzipien in den Entwicklungsprozess. Insbesondere im Kontext moderner Anforderungen des Mobility Management zeigt sich ihr Potenzial, nachhaltige Innovationen gezielt zu fördern und die Umsetzung der Kreislaufwirtschaft in der industriellen Praxis zu erleichtern."}]},{"publication":"Proceedings of the 15th International Conference on Formal Ontology in Information Systems","extern":"1","abstract":[{"lang":"eng","text":"Since the emergence of the field of eXplainable Artificial Intelligence (XAI), a growing number of researchers have argued that XAI should consider insights from the social sciences in order to adapt explanations to the expectations and needs of human users. This has led to the emergence of a field called Social XAI, which is concerned with understanding how explanations are actively shaped in the interaction between a human user and an AI system. Recognizing this turn in XAI toward making XAI systems more “social” by providing explanations that focus on human information needs and incorporating insights from human–human explanatory interactions, in this paper we provide a formal foundation for Social XAI. We do so by proposing novel ontological accounts of the key terms used in Social XAI based on Basic Formal Ontology (BFO). Specifically, we provide novel ontological accounts for explanandum, explanans, understanding, explanation, explainer, explainee, and context. In doing so, we discuss multifaceted entities in Social XAI (having both continuant and occurrent facets; e.g., explanation) and the relationship between understanding and explanation. Additionally, we propose solutions to seemingly paradoxical views on some terms (e.g., social constructivist vs. individual constructivist perspective on explanandum)."}],"date_created":"2025-09-08T14:00:45Z","type":"book_chapter","department":[{"_id":"660"}],"title":"A BFO-based ontological analysis of entities in Social XAI","year":"2025","publication_identifier":{"isbn":["9781643686172"],"issn":["0922-6389","1879-8314"]},"author":[{"id":"93424","last_name":"Booshehri","first_name":"Meisam","full_name":"Booshehri, Meisam"},{"orcid":"0000-0002-9613-5713","last_name":"Buschmeier","first_name":"Hendrik","full_name":"Buschmeier, Hendrik","id":"76456"},{"full_name":"Cimiano, Philipp","first_name":"Philipp","last_name":"Cimiano"}],"publication_status":"published","date_updated":"2025-09-11T10:16:28Z","main_file_link":[{"url":"https://doi.org/10.3233/FAIA250498","open_access":"1"}],"language":[{"iso":"eng"}],"doi":"10.3233/faia250498","citation":{"chicago":"Booshehri, Meisam, Hendrik Buschmeier, and Philipp Cimiano. “A BFO-Based Ontological Analysis of Entities in Social XAI.” In Proceedings of the 15th International Conference on Formal Ontology in Information Systems, 255–268.

However, the success of techniques depends on various parameters, such as the task, language model, and context provided. Finding an effective prompt is, therefore, often a trial-and-error process. Most existing approaches to automatic prompting aim to optimize individual techniques instead of compositions of techniques and their dependence on the input. To fill this gap, we propose an adaptive prompting approach that predicts the optimal prompt composition ad-hoc for a given input. We apply our approach to social bias detection, a highly context-dependent task that requires semantic understanding. We evaluate it with three large language models on three datasets, comparing compositions to individual techniques and other baselines. The results underline the importance of finding an effective prompt composition. Our approach robustly ensures high detection performance, and is best in several settings. Moreover, first experiments on other tasks support its generalizability.","lang":"eng"}],"publication":"Proceedings of the 2025 Conference of the Nations of the Americas Chapter of the Association for Computational Linguistics: Human Language Technologies (Volume 1: Long Papers)","type":"conference","department":[{"_id":"660"}],"date_created":"2025-05-10T12:37:45Z","publication_status":"published","date_updated":"2025-09-12T09:51:30Z","title":"Adaptive Prompting: Ad-hoc Prompt Composition for Social Bias Detection","year":"2025","publication_identifier":{"isbn":["979-8-89176-189-6"]},"author":[{"id":"84035","orcid":"0000-0003-4364-1409","first_name":"Maximilian","last_name":"Spliethöver","full_name":"Spliethöver, Maximilian"},{"last_name":"Knebler","first_name":"Tim","full_name":"Knebler, Tim"},{"last_name":"Fumagalli","first_name":"Fabian","full_name":"Fumagalli, Fabian","id":"93420"},{"last_name":"Muschalik","first_name":"Maximilian","full_name":"Muschalik, Maximilian"},{"full_name":"Hammer, Barbara","first_name":"Barbara","last_name":"Hammer"},{"full_name":"Hüllermeier, Eyke","first_name":"Eyke","last_name":"Hüllermeier","id":"48129"},{"id":"3900","full_name":"Wachsmuth, Henning","last_name":"Wachsmuth","first_name":"Henning"}],"main_file_link":[{"open_access":"1","url":"https://aclanthology.org/2025.naacl-long.122/"}],"language":[{"iso":"eng"}]},{"series_title":"Proceedings (SemDial)","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://purl.org/semdial/2025/proceedings"}],"publication_status":"published","date_updated":"2025-09-12T16:56:35Z","publication_identifier":{"issn":["2308-2275"]},"year":"2025","title":"SemDial 2025 – Bialogue.

DWs show very different properties as compared to their hosting bulk crystal, in particular with respect to the high local electrical conductivity. The objective of this work is to demonstrate DW conductivity up to temperatures as high as 400 °C which extends previous studies significantly. Experimental investigation of the DW conductivity of charged, inclined DWs is performed using 5 mol % MgO-doped lithium niobate single crystals. Current–voltage ( ) curves are determined by DC electrometer measurements and impedance spectroscopy and found to be identical. Moreover, impedance spectroscopy enables to recognize artifacts such as damaged electrodes. Temperature dependent measurements over repeated heating cycles reveal two distinct thermal activation energies for a given DW, with the higher of the activation energies only measured at higher temperatures. Depending on the specific sample, the higher activation energy is found above 160 °C to 230 °C. This suggests, in turn, that more than one type of defect/polaron is involved, and that the dominant transport mechanism changes with increasing temperature. First principles atomistic modeling suggests that the conductivity of inclined domain walls cannot be solely explained by the formation of a 2D carrier gas and must be supported by hopping processes. This holds true even at temperatures as high as 400 °C. Our investigations underline the potential to extend DW current based nanoelectronic and sensor applications even into the so-far unexplored temperature range up to 400 °C.","lang":"eng"}],"publication":"Solid State Ionics","department":[{"_id":"15"},{"_id":"288"},{"_id":"623"}],"type":"journal_article","date_created":"2025-09-17T16:18:18Z","article_type":"original","intvolume":" 429","publication_status":"published","date_updated":"2025-09-17T16:19:51Z","author":[{"full_name":"Wulfmeier, Hendrik","first_name":"Hendrik","last_name":"Wulfmeier"},{"full_name":"Yakhnevych, Uliana","last_name":"Yakhnevych","first_name":"Uliana"},{"full_name":"Boekhoff, Cornelius","first_name":"Cornelius","last_name":"Boekhoff"},{"full_name":"Diima, Allan","last_name":"Diima","first_name":"Allan"},{"full_name":"Kunzner, Marlo","first_name":"Marlo","last_name":"Kunzner"},{"first_name":"Leonard M.","last_name":"Verhoff","full_name":"Verhoff, Leonard M."},{"first_name":"Jonas","last_name":"Paul","full_name":"Paul, Jonas"},{"last_name":"Ratzenberger","first_name":"Julius","full_name":"Ratzenberger, Julius"},{"first_name":"Elke","last_name":"Beyreuther","full_name":"Beyreuther, Elke"},{"last_name":"Gössel","first_name":"Joshua","full_name":"Gössel, Joshua"},{"full_name":"Kiseleva, Iuliia","first_name":"Iuliia","last_name":"Kiseleva"},{"id":"22501","full_name":"Rüsing, Michael","orcid":"0000-0003-4682-4577","last_name":"Rüsing","first_name":"Michael"},{"first_name":"Simone","last_name":"Sanna","full_name":"Sanna, Simone"},{"full_name":"Eng, Lukas M.","last_name":"Eng","first_name":"Lukas M."},{"full_name":"Fritze, Holger","last_name":"Fritze","first_name":"Holger"}],"publication_identifier":{"issn":["0167-2738"]},"title":"Demonstration of domain wall current in MgO-doped lithium niobate single crystals up to 400°C","year":"2025","doi":"10.1016/j.ssi.2025.116949","language":[{"iso":"eng"}],"article_number":"116949","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1016/j.ssi.2025.116949"}]},{"publication":"Journal of Applied Physics","issue":"3","abstract":[{"lang":"eng","text":"Lithium niobate–tantalate mixed (LNT) crystals promise improved performance and new applications for optical, piezomechanical, or electrical devices when compared to the end composition compounds lithium niobate and lithium tantalate. The macroscopic properties of ferroelectrics highly depend on the structure of the underlying ferroelectric domains, which within mixed crystals can interact with the local changes in chemical compositions. In this work, we demonstrate how ferroelectric domain walls can unambiguously be identified and distinguished from local changes in composition by correlating piezoresponse force microscopy with second harmonic generation microscopy, using the Cherenkov contrast, reference crystal contrast, and negative phase mismatching contrast. We demonstrate how measuring the associated intensity change when approaching negative phase mismatching can be used to deduce the local tantalum concentration fast and over a large sample area. Based on these results, we study the natural domain structures that appear from Czochralski-grown, multi-domain LNT solid solution crystals. The developed results and methods serve as the central foundation to poling these mixed crystal systems and are key for their integration and applications."}],"date_created":"2025-09-17T16:16:04Z","type":"journal_article","department":[{"_id":"15"},{"_id":"623"}],"title":"Second harmonic generation contrasts of ferroelectric domain structures and composition in lithium niobate–tantalate mixed crystals","year":"2025","author":[{"full_name":"Koppitz, Boris","first_name":"Boris","last_name":"Koppitz"},{"full_name":"Saxena, Tanya","first_name":"Tanya","last_name":"Saxena"},{"first_name":"Felix","last_name":"Bernhardt","full_name":"Bernhardt, Felix"},{"full_name":"Ganschow, Steffen","first_name":"Steffen","last_name":"Ganschow"},{"last_name":"Sanna","first_name":"Simone","full_name":"Sanna, Simone"},{"id":"22501","first_name":"Michael","orcid":"0000-0003-4682-4577","last_name":"Rüsing","full_name":"Rüsing, Michael"},{"full_name":"Eng, Lukas M.","first_name":"Lukas M.","last_name":"Eng"}],"publication_identifier":{"issn":["0021-8979","1089-7550"]},"date_updated":"2025-09-17T16:18:02Z","publication_status":"published","intvolume":" 138","main_file_link":[{"url":"https://pubs.aip.org/aip/jap/article/138/3/034101/3352909","open_access":"1"}],"article_number":"034101","language":[{"iso":"eng"}],"doi":"10.1063/5.0276183","citation":{"bibtex":"@article{Koppitz_Saxena_Bernhardt_Ganschow_Sanna_Rüsing_Eng_2025, title={Second harmonic generation contrasts of ferroelectric domain structures and composition in lithium niobate–tantalate mixed crystals}, volume={138}, DOI={10.1063/5.0276183}, number={3034101}, journal={Journal of Applied Physics}, publisher={AIP Publishing}, author={Koppitz, Boris and Saxena, Tanya and Bernhardt, Felix and Ganschow, Steffen and Sanna, Simone and Rüsing, Michael and Eng, Lukas M.}, year={2025} }","chicago":"Koppitz, Boris, Tanya Saxena, Felix Bernhardt, Steffen Ganschow, Simone Sanna, Michael Rüsing, and Lukas M.

Der touristische Blick entsteht in zeitlicher und gedanklicher Nähe zum Kolonialismus\r\nund führt eine Form eurozentrisch-hegemonialer Weltbeherrschung vor ‒ wobei der Tourist\r\nals Typus auch im Inland schon im 19. Jahrhundert dem Reisenden als Negativfigur entgegengestellt\r\nwird. Entgegen gegenwärtiger Werbestrategien ist auch der Kulturtourismus von seinen Anfängen her\r\nnicht frei von Elementen des Massentourismus und eines die Fremde beherrschenden Blicks. Dass eine\r\nimmer schon vorgeprägte Erwartungshaltung die erwartete Erschütterung erschwert, wird Rilke auf seiner\r\nReise deutlich, die er nicht zuletzt durch die Ägypten-Reise seiner Frau vorbereitet hat. So versucht\r\ner den Ambivalenzen des industrialisierten Kulturtourismus zu entkommen und empfindet am Ende\r\ndoch nur die strukturelle Untragbarkeit der touristischen Situation, die schon vor der Reise durch die\r\nHoffnung auf authentisches Erleben hoffnungslos kontaminiert ist.","lang":"eng"}],"language":[{"iso":"ger"}],"main_file_link":[{"open_access":"1","url":"https://indigo.uni-paderborn.de/magazin/dimag-ausgabe-2/"}],"doi":"10.17619/UNIPB/1-2182","author":[{"full_name":"Schulte Eickholt, Swen","last_name":"Schulte Eickholt","first_name":"Swen"}],"publication_identifier":{"issn":["2943-3010"]},"title":"Das Gesicht des Weltalls anschauen.

With the advent of distributed communication networks like the Internet and decentralized ledger technologies like blockchain, new platforms emerged, disrupting existing power dynamics and bringing about new claims of sovereignty from the private sector. This special issue addresses a gap in the literature by focusing the discourse on the issue of trust and confidence in the digital realm. In particular, looking at the evolution of the web (from Web 1.0, to Web 2.0, and then Web 3), this article analyses how every iteration reflects a different way of dealing with the problem of trust online, resulting in a different regulation and governance landscape. Technology is often regarded as a new lever of regulation, attempting to resolve the problem of “trust” online, either through the introduction of a new trusted authority (Web 2.0) or through the introduction of technological guarantees that provide more assurance—or “confidence”—in the way interactions can be operationalized (Web 3). Yet, each of these technologies also introduce new risks and governance costs, ultimately shifting the problem of trust in a new direction rather than resolving it or removing the need for trust altogether. The main contribution of the articles in this special issue is providing a better understanding of the trust challenges faced and posed by emerging technologies and demonstrating how they affect institutional governance—in both theory and practice—with a view to help policymakers find appropriate answers to these challenges.","lang":"eng"}],"date_created":"2025-06-16T20:36:42Z","type":"journal_article"},{"type":"conference_abstract","department":[{"_id":"150"},{"_id":"300"}],"file":[{"file_size":349667,"access_level":"open_access","file_name":"250922_MINT_Erfolgreich studieren.pdf","date_updated":"2025-09-22T12:46:35Z","relation":"main_file","content_type":"application/pdf","file_id":"61397","creator":"noelflor","date_created":"2025-09-22T11:36:05Z"}],"date_created":"2025-09-22T11:39:21Z","publication":"MINT-Symposium","language":[{"iso":"ger"}],"publication_status":"published","date_updated":"2025-09-22T12:46:53Z","year":"2025","title":"Erfolgreich Studieren - sinnvolle Lernstrategien erlernen (Posterbeitrag)","author":[{"full_name":"Nölle, Florian","last_name":"Nölle","first_name":"Florian","id":"50522"},{"id":"464","last_name":"Schmid","first_name":"Hans-Joachim","orcid":"000-0001-8590-1921","full_name":"Schmid, Hans-Joachim"},{"id":"65001","first_name":"Leon Alexander","last_name":"Bentrup","full_name":"Bentrup, Leon Alexander"},{"id":"30086","first_name":"Katrin","last_name":"Temmen","full_name":"Temmen, Katrin"}],"oa":"1","place":"Nürnberg","project":[{"name":"DigiSelF - Digitalisierung als Herausforderung und Innovation in der Hochschullehre","_id":"1387"}],"file_date_updated":"2025-09-22T12:46:35Z","citation":{"bibtex":"@inproceedings{Nölle_Schmid_Bentrup_Temmen_2025, place={Nürnberg}, title={Erfolgreich Studieren - sinnvolle Lernstrategien erlernen (Posterbeitrag)}, booktitle={MINT-Symposium}, author={Nölle, Florian and Schmid, Hans-Joachim and Bentrup, Leon Alexander and Temmen, Katrin}, year={2025} }","chicago":"Nölle, Florian, Hans-Joachim Schmid, Leon Alexander Bentrup, and Katrin Temmen. “Erfolgreich Studieren - sinnvolle Lernstrategien erlernen (Posterbeitrag).” In MINT-Symposium.
