In today’s dynamic environments—shaped by digital transformation,\r\nevolving provider–user interactions, and shifting societal demands—these approaches face limitations in enabling continuous, context-sensitive innovation. Continuous Value Shaping emerges as a conceptual extension to service systems engineering, promoting more adaptive and co-evolutionary forms of service system development. This study examines how Continuous Value Shaping manifests through a multiple case study of three public sector projects. We identify distinct manifestations and constellations of the concept’s principles that complement classical\r\nSSE practices. As the first empirical exploration of Continuous Value Shaping, the study refines its\r\nconceptual foundation and enhances its accessibility for researchers and practitioners. We conclude with seven empirically derived propositions that inform future service systems engineering initiatives and demonstrate how Continuous Value Shaping supports the dynamic alignment of service systems with societal and systemic demands."}],"language":[{"iso":"eng"}],"author":[{"id":"74374","first_name":"Jannika Marie","last_name":"Schäfer","full_name":"Schäfer, Jannika Marie"},{"last_name":"Rajko","first_name":"Polina","full_name":"Rajko, Polina"},{"last_name":"Angelova","first_name":"Daniela","full_name":"Angelova, Daniela"},{"full_name":"Böhmann, Tilo","last_name":"Böhmann","first_name":"Tilo"}],"year":"2026","title":"From Engineering to Shaping: A Multiple Case Study on Advancing Service Systems Engineering through Continuous Value Shaping","publication_status":"published","date_updated":"2026-02-05T06:57:02Z","place":"Maui, Hawaii, USA","citation":{"bibtex":"@inproceedings{Schäfer_Rajko_Angelova_Böhmann_2026, place={Maui, Hawaii, USA}, title={From Engineering to Shaping: A Multiple Case Study on Advancing Service Systems Engineering through Continuous Value Shaping}, booktitle={Proceedings of the 59th Hawaii International Conference on System Sciences (HICSS 2026)}, publisher={Association for Information Systems (AIS), IEEE Computer Society Press, University of Hawaii (Manoa)}, author={Schäfer, Jannika Marie and Rajko, Polina and Angelova, Daniela and Böhmann, Tilo}, year={2026} }","ama":"Schäfer JM, Rajko P, Angelova D, Böhmann T.

It is particularly relevant in scenarios where understanding and predicting conditional \r\nvariability is crucial, such as when dealing with incremental or time-dependent data. In this paper, novel \r\nshort and long memory volatility models of the EGARCH family are introduced and analyzed, which \r\nare closely related to the well-established EGARCH model proposed by Nelson (1991) but share \r\ndesirable theoretical properties in several dimensions. Recently developed members of the so-called \r\nEGARCH family, which introduces a modulus-log transformation proposed by John and Draper (1980) \r\nand a power transformation for the size and magnitude effect to tackle the problem with near-zero \r\ninnovations and the asymmetric impact of positive and negative shocks on the volatility, are discussed. \r\nAfter a theoretical discussion of the proposed and related volatility models, the practical performance \r\nof the elaborated volatility models is compared to well-established and traditional GARCH approaches. \r\nA general QMLE algorithm is proposed to estimate the model parameters. The practical relevance of the \r\nadvanced models is illustrated through a comparative study. By applying these volatility models to a \r\nvariety of international stock index returns, this paper identifies market-specific characteristics as well \r\nas unique strengths and weaknesses of discussed volatility models. Although the practical performance \r\nof the recently introduced models is comparable to those obtained by the traditional EGARCH model, \r\nthey generally outperform traditional non-exponential volatility models used as benchmarks and thus \r\nprovide a useful alternative to existing short and long memory volatility models.

Im Fokus stehen die Erfahrungen von Seiteneinsteiger:innen sowie die Perspektiven der Lehrkräfte, die im Rahmen einer qualitativ‑explorativen Untersuchung mithilfe von Unterrichtshospitationen, Interviews und Materialanalysen erhoben wurden. Methodisch ist die Arbeit in der Grounded Theory Methodology nach Strauss und Corbin (1996) verankert, anhand derer die komplexen Einflussfaktoren historischer Leseprozesse systematisch herausgearbeitet werden.\r\n\r\nDie Ergebnisse zeigen drei zentrale Einflussdimensionen: sprachliche, sozial‑affektive und geschichtsspezifische Faktoren. Zudem wird deutlich, dass Unterstützungsmaßnahmen stets zwischen kurzfristiger Hilfe und dem langfristigen Aufbau von Disciplinary Literacy ausbalanciert werden müssen. Ihre Wirksamkeit hängt wesentlich von der bewussten Auswahl und Zugänglichkeit durch die Lehrkraft sowie von den Möglichkeiten der Lernenden ab, Unterstützung gezielt einzufordern. Lernwirksam wird Geschichtsunterricht besonders dann, wenn hohe fachliche Anforderungen mit reflektierter sprachlicher Unterstützung verbunden werden.

Meanwhile, socially situated ‘end-users’ experience harms, such as hidden labor, reinforced stereotypes, and increased unpredictability, as machine learning advances. However, accurately modeling social context does not constitute design justice. This paper reinterprets Giuseppe Mantovani’s model of social context in human-computer interaction (HCI) to address the relational emergence and political situatedness of social context in human-AI interaction (HAI). Drawing on the concept of a multi-perspectival algorithmic imaginary, we (1) conceptualize context as nested and entangled relations, (2) identify actors, including users, developers, models, and interfaces, and (3) foreground the organization of relations of power. Recognizing that models are performative rather than predictive, we argue that the sociopolitical situatedness of context must be acknowledged alongside its limits. To challenge design authority, we propose that HCI and HAI strategically foster intra-actional negotiability, enabling users to challenge, reinterpret, or modify their relationship with technology through critical (design) practices.","lang":"eng"}],"publication":"HCI International 2026 Posters: 28th International Conference on Human-Computer Interaction, HCII 2026, Montreal, QC, Canada, July 26–31, 2026, Proceedings, Part I","type":"book_chapter","keyword":["Social Context","Situatedness","Imaginaries"],"department":[{"_id":"757"}],"date_created":"2025-12-11T10:14:17Z","publication_status":"published","date_updated":"2026-07-23T10:02:20Z","intvolume":" 3047","title":"Social Context in Human-AI Interaction (HAI): Towards a Theoretical Framework Based on Multi-Perspectival Imaginaries","year":"2026","author":[{"full_name":"Menne, Anna Lena","last_name":"Menne","orcid":"0009-0008-0744-9165","first_name":"Anna Lena","id":"118085"},{"id":"72684","full_name":"Schulz, Christian","last_name":"Schulz","first_name":"Christian"}],"doi":"10.1007/978-3-032-30552-7_10","main_file_link":[{"url":"https://link.springer.com/chapter/10.1007/978-3-032-30552-7_10"}],"language":[{"iso":"eng"}],"series_title":"Communications in Computer and Information Science (CCIS)","project":[{"name":"TRR 318: Erklärbarkeit konstruieren","_id":"109"}],"citation":{"mla":"Menne, Anna Lena, and Christian Schulz. “Social Context in Human-AI Interaction (HAI): Towards a Theoretical Framework Based on Multi-Perspectival Imaginaries.” HCI International 2026 Posters: 28th International Conference on Human-Computer Interaction, HCII 2026, Montreal, QC, Canada, July 26–31, 2026, Proceedings, Part I, edited by Constantine Stephanidis et al., vol. 3047, Springer International Publishing, 2026, pp. 93–106, doi:10.1007/978-3-032-30552-7_10.","bibtex":"@inbook{Menne_Schulz_2026, series={Communications in Computer and Information Science (CCIS)}, title={Social Context in Human-AI Interaction (HAI): Towards a Theoretical Framework Based on Multi-Perspectival Imaginaries}, volume={3047}, DOI={10.1007/978-3-032-30552-7_10}, booktitle={HCI International 2026 Posters: 28th International Conference on Human-Computer Interaction, HCII 2026, Montreal, QC, Canada, July 26–31, 2026, Proceedings, Part I}, publisher={Springer International Publishing}, author={Menne, Anna Lena and Schulz, Christian}, editor={Stephanidis, Constantine and Margetis, George and Ntoa, Stavroula and Antona, Margherita and Salvendy, Gavriel}, year={2026}, pages={93–106}, collection={Communications in Computer and Information Science (CCIS)} }","ama":"Menne AL, Schulz C.

A typical conception,\r\nfor example in the context of medical diagnosis, is that a knowledgeable user receives AIgenerated\r\nclassification as advice. Research to improve such interactions often aims to foster the\r\nuser’s trust, which in turn should improve the combined human-AI performance. Given that AI\r\nmodels can err, we argue that the possibility to critically review, thus to distrust, an AI decision is\r\nan equally interesting target of research.\r\nWe created two image classification scenarios in which the participants received mock-up\r\nAI advice. The quality of the advice decreases for a phase of the experiment. We studied the\r\ntask performance, trust and distrust of the participants, and tested whether an instruction to\r\nremain skeptical and review each piece of advice led to a better performance compared to a\r\nneutral condition. Our results indicate that this instruction does not improve but rather worsens\r\nthe participants’ performance. Repeated single-item self-report of trust and distrust shows an\r\nincrease in trust and a decrease in distrust after the drop in the AI’s classification quality, with no\r\ndifference between the two instructions. Furthermore, via a Bayesian Signal Detection Theory\r\nanalysis, we provide a procedure to assess appropriate reliance in detail, by quantifying whether\r\nthe problems of under- and over-reliance have been mitigated. We discuss implications of our\r\nresults for the usage of disclaimers before interacting with AI, as prominently used in current\r\nLLM-based chatbots, and for trust and distrust research.","lang":"eng"}],"publication":"Frontiers in Psychology","user_id":"92810","volume":16,"_id":"59755","status":"public","project":[{"_id":"124","name":"TRR 318 - C1: TRR 318 - Subproject C1 - Gesundes Misstrauen in Erklärungen"}],"citation":{"chicago":"Peters, Tobias Martin, and Ingrid Scharlau. “Interacting with Fallible AI: Is Distrust Helpful When Receiving AI Misclassifications?” Frontiers in Psychology 16 (2025). https://doi.org/10.3389/fpsyg.2025.1574809.","short":"T.M.

Recent advances in artificial intelligence, including learning approaches like reinforcement\r\nlearning and architectures like transformers and foundation models, combined with access to massive datasets, has created attractive\r\nopportunities to apply those data-hungry techniques to this problem. We argue that the focus on massive amounts of pre-collected\r\ndata, and the resulting learning paradigm, where humans demonstrate and robots learn in isolation, is overshadowing a specialized\r\narea of work we term Human-Interactive-Robot-Learning (HIRL). This paradigm, wherein robots and humans interact during the\r\nlearning process, is at the intersection of multiple fields (artificial intelligence, robotics, human-computer interaction, design and others)\r\nand holds unique promise. Using HIRL, robots can achieve greater sample efficiency (as humans can provide task knowledge through\r\ninteraction), align with human preferences (as humans can guide the robot behavior towards their expectations), and explore more\r\nmeaningfully and safely (as humans can utilize domain knowledge to guide learning and prevent catastrophic failures). This can result\r\nin robotic systems that can more quickly and easily adapt to new tasks in human environments. The objective of this paper is to\r\nprovide a broad and consistent overview of HIRL research and to guide researchers toward understanding the scope of HIRL, and\r\ncurrent open or underexplored challenges related to four themes — namely, human, robot learning, interaction, and broader context.\r\nThe paper includes concrete use cases to illustrate the interaction between these challenges and inspire further research according to\r\nbroad recommendations and a call for action for the growing HIRL community","lang":"eng"}],"project":[{"_id":"123","name":"TRR 318 - Subproject B5"}],"date_created":"2025-09-17T12:42:45Z","keyword":["Robot learning","Interactive learning systems","Human-robot interaction","Human-in-the-loop machine learning","Teaching and learning"],"type":"journal_article","status":"public","title":"Human-Interactive Robot Learning: Definition, Challenges, and Recommendations","year":"2025","author":[{"first_name":"Kim ","last_name":"Baraka","full_name":"Baraka, Kim "},{"full_name":"Idrees, Ifrah","first_name":"Ifrah","last_name":"Idrees"},{"full_name":"Faulkner, Taylor Kessler","last_name":"Faulkner","first_name":"Taylor Kessler"},{"full_name":"Biyik, Erdem","first_name":"Erdem","last_name":"Biyik"},{"full_name":"Booth, Serena","last_name":"Booth","first_name":"Serena"},{"first_name":"Mohamed","last_name":"Chetouani","full_name":"Chetouani, Mohamed"},{"last_name":"Grollman","first_name":"Daniel H.","full_name":"Grollman, Daniel H."},{"full_name":"Saran, Akanksha","last_name":"Saran","first_name":"Akanksha"},{"full_name":"Senft, Emmanuel","first_name":"Emmanuel","last_name":"Senft"},{"full_name":"Tulli, Silvia","last_name":"Tulli","first_name":"Silvia"},{"first_name":"Anna-Lisa","last_name":"Vollmer","full_name":"Vollmer, Anna-Lisa"},{"full_name":"Andriella, Antonio","last_name":"Andriella","first_name":"Antonio"},{"last_name":"Beierling","first_name":"Helen","full_name":"Beierling, Helen"},{"first_name":"Tiffany","last_name":"Horter","full_name":"Horter, Tiffany"},{"full_name":"Kober, Jens","first_name":"Jens","last_name":"Kober"},{"full_name":"Sheidlower, Isaac","first_name":"Isaac","last_name":"Sheidlower"},{"full_name":"Taylor, Matthew E.","last_name":"Taylor","first_name":"Matthew E."},{"full_name":"van Waveren, Sanne","last_name":"van Waveren","first_name":"Sanne"},{"full_name":"Xiao, Xuesu","last_name":"Xiao","first_name":"Xuesu"}],"date_updated":"2025-09-17T13:40:16Z","publication_status":"submitted","article_type":"original","_id":"61327","language":[{"iso":"eng"}],"user_id":"50995"},{"external_id":{"unknown":["https://link.springer.com/article/10.1007/s12525-025-00771-1"]},"citation":{"mla":"Böhmann, Tilo, et al. “Continuous Value Shaping: A Boundary Concept for Innovating Service Innovation Approaches.” Electronic Markets, vol. 35, no. 1, 27, Springer Science and Business Media LLC, 2025, doi:10.1007/s12525-025-00771-1.","bibtex":"@article{Böhmann_Roth_Satzger_Benz_Beverungen_Boes_Breidbach_Gersch_Gudergan_Hogreve_et al._2025, title={Continuous value shaping: A boundary concept for innovating service innovation approaches}, volume={35}, DOI={10.1007/s12525-025-00771-1}, number={127}, journal={Electronic Markets}, publisher={Springer Science and Business Media LLC}, author={Böhmann, Tilo and Roth, Angela and Satzger, Gerhard and Benz, Carina and Beverungen, Daniel and Boes, Andreas and Breidbach, Christoph and Gersch, Martin and Gudergan, Gerhard and Hogreve, Jens and et al.}, year={2025} }","ama":"Böhmann T, Roth A, Satzger G, et al.

While a variety of disciplines are developing new approaches to drive service innovation, this is primarily done in isolation and generates only fragmented solutions. Sociological theory has proposed “boundary objects” as an effective umbrella for communication and cooperation among communities. Therefore, we introduce continuous value shaping (CVS) as a boundary object describing service innovation approaches along five principles. We reflect on this concept through the different disciplinary lenses of researchers in service marketing, information systems, service engineering, sociology of work, and innovation management. These perspectives highlight how the CVS principles already connect to discourses within the individual disciplines. However, the CVS concept will not only provide an umbrella to embrace existing activities in different academic disciplines. It also assists to identify research themes that will benefit from uniting the power of these disciplines, and it can serve as an integrating framework to conceptualize complex service innovation approaches. Thus, the CVS concept should guide both researchers and practitioners to develop and implement novel innovation and transformation efforts—in and across organizations.","lang":"eng"}],"language":[{"iso":"eng"}],"article_number":"27","doi":"10.1007/s12525-025-00771-1","author":[{"first_name":"Tilo","last_name":"Böhmann","full_name":"Böhmann, Tilo"},{"full_name":"Roth, Angela","first_name":"Angela","last_name":"Roth"},{"first_name":"Gerhard","last_name":"Satzger","full_name":"Satzger, Gerhard"},{"full_name":"Benz, Carina","first_name":"Carina","last_name":"Benz"},{"last_name":"Beverungen","first_name":"Daniel","full_name":"Beverungen, Daniel"},{"last_name":"Boes","first_name":"Andreas","full_name":"Boes, Andreas"},{"full_name":"Breidbach, Christoph","first_name":"Christoph","last_name":"Breidbach"},{"last_name":"Gersch","first_name":"Martin","full_name":"Gersch, Martin"},{"full_name":"Gudergan, Gerhard","last_name":"Gudergan","first_name":"Gerhard"},{"full_name":"Hogreve, Jens","last_name":"Hogreve","first_name":"Jens"},{"full_name":"Kurtz, Christian","first_name":"Christian","last_name":"Kurtz"},{"last_name":"Langes","first_name":"Barbara","full_name":"Langes, Barbara"},{"full_name":"Leimeister, Jan Marco","last_name":"Leimeister","first_name":"Jan Marco"},{"last_name":"Lewandowski","first_name":"Tom","full_name":"Lewandowski, Tom"},{"last_name":"Meiren","first_name":"Thomas","full_name":"Meiren, Thomas"},{"last_name":"Nägele","first_name":"Rainer","full_name":"Nägele, Rainer"},{"full_name":"Paluch, Stefanie","last_name":"Paluch","first_name":"Stefanie"},{"full_name":"Peters, Christoph","last_name":"Peters","first_name":"Christoph"},{"first_name":"Jens","last_name":"Poeppelbuss","full_name":"Poeppelbuss, Jens"},{"full_name":"Robra-Bissantz, Susanne","first_name":"Susanne","last_name":"Robra-Bissantz"},{"full_name":"Schultz, Carsten","first_name":"Carsten","last_name":"Schultz"},{"full_name":"Schumann, Jan H.","last_name":"Schumann","first_name":"Jan H."},{"full_name":"Wirtz, Jochen","last_name":"Wirtz","first_name":"Jochen"},{"last_name":"Wünderlich","first_name":"Nancy V.","full_name":"Wünderlich, Nancy V."}],"publication_identifier":{"issn":["1019-6781","1422-8890"]},"title":"Continuous value shaping: A boundary concept for innovating service innovation approaches","year":"2025","article_type":"original","intvolume":" 35","publication_status":"published","date_updated":"2025-11-10T10:19:25Z"},{"abstract":[{"lang":"eng","text":"Titanium alloys are widely employed for biomedical implants due to their high strength, biocompatibility, and corrosion resistance, yet their lack of intrinsic antibacterial activity remains a major limitation. Incorporating copper, an antibacterial and β-stabilising element, offers a promising strategy to enhance implant performance. This study investigates Ti-6Al-7Nb modified with 1–9 wt.% Cu via in situ alloying during metal-based laser powder bed fusion (PBF-LB/M), with the aim of assessing processability, microstructural evolution, and mechanical properties. Highly dense samples (>99.9%) were produced across all Cu levels, though chemical homogeneity strongly depended on processing parameters. Increasing Cu content promoted β-phase stabilisation, Ti2Cu precipitation, and pronounced grain refinement. Hardness and yield strength increased nearly linearly with Cu addition, while ductility decreased sharply at ≥5 wt.% Cu due to intermetallic formation, hot cracking, and brittle fracture. These results illustrate both the opportunities and constraints of rapid alloy screening via PBF-LB/M. Overall, moderate Cu additions of 1–3 wt.% provide the most favourable balance between mechanical performance, manufacturability, and potential antibacterial functionality. These findings provide a clear guideline for the design of Cu-functionalised titanium implants and demonstrate the efficiency of in situ alloy screening for accelerated materials development."}],"issue":"12","publication":"Crystals","department":[{"_id":"158"},{"_id":"321"}],"type":"journal_article","keyword":["Biomaterial","In Situ Alloying","Titanium","Additive Manufacturing"],"date_created":"2025-12-12T13:11:59Z","file":[{"file_size":20716652,"access_level":"closed","file_name":"crystals-15-01053.pdf","date_updated":"2025-12-12T13:12:33Z","relation":"main_file","content_type":"application/pdf","success":1,"file_id":"63073","creator":"paulstei","date_created":"2025-12-12T13:12:33Z"}],"intvolume":" 15","article_type":"original","date_updated":"2025-12-12T14:02:13Z","publication_status":"published","publication_identifier":{"issn":["2073-4352"]},"author":[{"first_name":"Paul","last_name":"Steinmeier","full_name":"Steinmeier, Paul"},{"last_name":"Hoyer","first_name":"Kay-Peter","full_name":"Hoyer, Kay-Peter"},{"full_name":"Lopes Dias, Nelson Filipe","last_name":"Lopes Dias","first_name":"Nelson Filipe"},{"full_name":"Zielke, Reiner","first_name":"Reiner","last_name":"Zielke"},{"first_name":"Wolfgang","last_name":"Tillmann","full_name":"Tillmann, Wolfgang"},{"last_name":"Schaper","first_name":"Mirko","full_name":"Schaper, Mirko"}],"title":"In Situ Alloying of Ti-6Al-7Nb with Copper Using Laser Powder Bed Fusion","year":"2025","doi":"10.3390/cryst15121053","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://doi.org/10.3390/cryst15121053","open_access":"1"}],"article_number":"1053","quality_controlled":"1","citation":{"apa":"Steinmeier, P., Hoyer, K.-P., Lopes Dias, N.

Introducing causality into the modelling process offers a promising way to mitigate these challenges by enhancing predictive robustness. However, constructing an initial causal graph manually using domain knowledge is time-consuming, particularly in complex time series with numerous variables. To address this, causal discovery algorithms can provide a preliminary causal structure that domain experts can refine. This study investigates causal feature selection with domain knowledge using a data center system as an example. We use simulated time-series data to compare \r\ndifferent causal feature selection with traditional machine-learning feature selection methods. Our results show that predictions based on causal features are more robust compared to those derived from traditional methods. These findings underscore the potential of combining causal discovery algorithms with human expertise to improve machine learning applications.","lang":"eng"}],"citation":{"ieee":"D. R.

Thus, in 2019, the so-called SpraySyn1 burner was introduced (SS1), which was subsequently characterized in numerical and experimental studies. Based on this research, a modification of the nozzle design was proposed, which has now been considered in the successor model, SpraySyn2 (SS2). As little is known about the effect of the nozzle adaptation on the particle formation, we operated both burners under identical operating conditions to produce maghemite. The final powder comparison showed that SS2 yielded considerable higher specific surface areas (associated with smaller primary particle sizes), lower polydispersity, and higher phase purity. To obtain further information on the size distributions of aggregates and agglomerates generated by SS2, aerosol samples were extracted by hole in a tube (HIAT) sampling and characterized by scanning mobility particle sizing (SMPS). Samples were extracted along the centerline at different heights above the burner (HAB) above the visible flame tip (>7 cm), and quenching experiments were performed to extract the aerosol samples at different dilution rates. Thereby, it was demonstrated that performing detailed quenching experiments is crucial for obtaining representative HIAT-SMPS data. In particular, agglomerates/aggregate sizes were overestimated by up to ~70 % if samples were not sufficiently diluted. If sufficient dilution was applied, distribution widths and mean particle mobility diameters were determined with high accuracy (sample standard derivation <5 %). Our data suggested the evolution of primary particle sizes was mostly completed <7 cm HAB and it was shown aggregates/agglomerates present above the visible flame were compact in structure (non- fractal). The mean diameter of the particle ensemble grew along the centerline from 6.9 nm (7 cm) to 11.4 nm (15 cm), while distribution widths grew from 1.42 to 1.52."}],"date_created":"2024-02-05T12:02:57Z","department":[{"_id":"150"}],"keyword":["Flame Spray Pyrolysis","SpraySyn2","Spray flame synthesis","Maghemite nanoparticles","Gas to particle-conversion","Hole in a tube sampling"],"type":"journal_editor","status":"public","has_accepted_license":"1","_id":"51133","publisher":"Elsevier","editor":[{"id":"67002","first_name":"Ricardo","last_name":"Tischendorf","full_name":"Tischendorf, Ricardo"},{"full_name":"Massopo, Orlando","last_name":"Massopo","first_name":"Orlando","id":"98419"},{"id":"464","last_name":"Schmid","first_name":"Hans-Joachim","orcid":"000-0001-8590-1921","full_name":"Schmid, Hans-Joachim"},{"first_name":"Olek","last_name":"Pyrmak","full_name":"Pyrmak, Olek"},{"full_name":"Dupont, Sophie","first_name":"Sophie","last_name":"Dupont"},{"last_name":"Fröde","first_name":"Fabian","full_name":"Fröde, Fabian"},{"first_name":"Heinz","last_name":"Pitsch","full_name":"Pitsch, Heinz"},{"last_name":"Kneer","first_name":"Reinhold","full_name":"Kneer, Reinhold"}],"user_id":"98419","ddc":["660"],"citation":{"ama":"Tischendorf R, Massopo O, Schmid H-J, et al., eds.

This paper explores the value of a reputation system for a business-to-business (B2B) context and focuses on three novel solutions for designing reputation systems. These solutions include selling ratings, conducting ratings as payments, and employing a counter-rating mechanism. We interview buyers to fathom the added value of these solutions in different contexts. Our findings suggest that such a system is useful for companies acting in less transparent markets and also helps when companies already have a good market overview.

Diese meist sozialpädagogisch ausgebildeten Fachkräfte sind dezidiert für die Unterstützung der Inklusion an Grund-, Sekundar-und Gesamtschulen angestellt. Erste Befunde (Grüter et al.,2022) und ministeriale Aufgabenbeschreibung (Ministerium für Schule und Bildung des Landes Nordrhein-Westfalen [MSB NRW], 2022) deuten auf ein offenes, wenig definiertes Tätigkeitsspektrum hin. Mögliche Aufgabengebiete der MPT überschneiden sich mit denen der (sonderpädagogischen) Lehrkräfte, der Schulsozialarbeiter*innen und –im Hinblick auf die Unterstützung im Unterricht ohne Unterrichtsverantwortung –mit denen der Schulbegleitungen (Lübeck, 2019).Die Überlappungen legen nahe, dass auch für die MPT das „Zuständigkeitsdiffusitätsproblem“ (Kunze 2016, S.265) gilt und die multiprofessionelle Teamarbeit entsprechend beeinflusst. Da es bislang keine Daten darüber gibt, wie sich die Berufsrolle von MPT-Kräften in der Breite ausgestaltet, eruiert der Beitrag in einer quantitativen Studie ebendiese Frage. Zusätzlich werden die Fragenfokussiert, über welche Qualifikationen und Vorerfahrungen MPT-Kräfte verfügen und mit welchen Akteur*innen MPT-Kräfte in welcher Form kooperieren. Die Untersuchung bezieht sich auf den Einsatz von MPT an Gesamt-und Sekundarschulen in NRW. Insgesamt wurden 109 MPT-Kräfte in Form eines Online-Fragebogens befragt. Anhand der Ergebnisse konnte ein breites Einsatzgebiet mit vereinzelten Aufgabenschwerpunkten (v.a. im Bereich der sonderpädagogisch orientierten Kleingruppenförderung) der MPT-Kräfteidentifiziert werden. Schnittmengen zu Aufgabenschwerpunkten anderer Berufsgruppen werden unter Berücksichtigung der multiprofessionellen Kooperation hinsichtlich der Frage diskutiert, ob der Einsatz von MPT-Kräften inklusive Zielstellungen eher befördert oder im Sinne einer Deprofessionalisierung sonderpädagogischer Förderung eher entgegensteht.","lang":"ger"}],"publication":"Zeitschrift für Inklusion","issue":"5","department":[{"_id":"450"}],"type":"journal_article","keyword":["Deprofessionalisierung","Kooperation","Fachkräfte für das Multiprofessionelle Team(MPT)","Aufgabenprofile in der inklusiven Schule"],"date_created":"2025-01-07T10:15:03Z","article_type":"original","date_updated":"2025-01-23T17:13:11Z","publication_status":"published","author":[{"id":"56091","last_name":"Meusel","first_name":"Sarah","full_name":"Meusel, Sarah"},{"id":"83570","full_name":"Müller, Lukas","first_name":"Lukas","last_name":"Müller"},{"id":"94539","full_name":"Jesuthasan, Jonitta","last_name":"Jesuthasan","first_name":"Jonitta"}],"year":"2024","title":"Bestimmt unbestimmt? - Eine quantitativ-explorative Studie zu Aufgabenprofilen von Fachkräften für das Multiprofessionelle Team (MPT) an inklusiven Gesamt-und Sekundarschulen in NRW.","language":[{"iso":"ger"}],"main_file_link":[{"url":"https://www.inklusion-online.net/index.php/inklusion-online/article/view/816","open_access":"1"}]},{"abstract":[{"text":"In our paper, we present a study in which we investigate which strategies pre-service teachers (PSTs) use to find and, if necessary, reject possible candidates for congruence theorems for quadrilaterals. This study was conducted before the PTSs attended a university geometry course. In this way, statements about learning prerequisites can be made. For the study, we analyzed group discussions of PSTs to identify typical approaches and evaluate them from a mathematical perspective. The results can be considered for the further development of courses for PSTs and generate hypotheses\r\nfor further research.","lang":"eng"}],"publication":"Proceedings of the Fifth Conference of the International Network for Didactic Research in University Mathematics (INDRUM 2024, 10-14 June 2024)","department":[{"_id":"97"},{"_id":"643"}],"keyword":["Teachers’ and students’ practices at university level","Transition to","across and from university mathematics","Teaching and learning of specific topics in university mathematics","Congruence","Quadrilaterals"],"type":"conference","date_created":"2025-01-02T10:45:53Z","file":[{"access_level":"closed","file_size":315111,"file_name":"2024_Hoffmann_Schlueter_CongruenceQuadrilaterals.pdf","date_updated":"2025-01-02T10:42:21Z","relation":"main_file","content_type":"application/pdf","success":1,"file_id":"57896","creator":"maxh","date_created":"2025-01-02T10:42:21Z"}],"publication_status":"published","date_updated":"2025-01-02T10:45:59Z","author":[{"full_name":"Hoffmann, Max","first_name":"Max","last_name":"Hoffmann","orcid":"0000-0002-6964-7123","id":"32202"},{"first_name":"Sarah","last_name":"Schlüter","full_name":"Schlüter, Sarah"}],"title":"How Do Advanced Pre-Service Teachers Develop Congruence Theorems for Quadrilaterals?","year":"2024","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://indrum2024.sciencesconf.org/data/pages/Proceedings_INDRUM2024.pdf"}],"quality_controlled":"1","citation":{"short":"M.

Verifying a given claim typically entails validating it within the framework of supporting evidence like a retrieved piece of text. Classifying the stance of the text with respect to the claim is called stance classification. Despite advancements in automated fact-checking, most systems still rely on a substantial quantity of labeled training data, which can be costly. In this work, we avoid the costly training or fine-tuning of models by reusing pre-trained large language models together with few-shot in-context learning. Since we do not train any model, our approach ExPrompt is lightweight, demands fewer resources than other stance classification methods and can serve as a modern baseline for future developments. At the same time, our evaluation shows that our approach is able to outperform former state-of-the-art stance classification approaches regarding accuracy by at least 2 percent.
