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." author: - first_name: Jannika Marie full_name: Schäfer, Jannika Marie id: '74374' last_name: Schäfer - first_name: Polina full_name: Rajko, Polina last_name: Rajko - first_name: Daniela full_name: Angelova, Daniela last_name: Angelova - first_name: Tilo full_name: Böhmann, Tilo last_name: Böhmann citation: ama: 'Schäfer JM, Rajko P, Angelova D, Böhmann T.

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." article_type: original author: - first_name: Tobias Martin full_name: Peters, Tobias Martin id: '92810' last_name: Peters orcid: 0009-0008-5193-6243 - first_name: Ingrid full_name: Scharlau, Ingrid id: '451' last_name: Scharlau orcid: 0000-0003-2364-9489 citation: ama: 'Peters TM, Scharlau I.

To evaluate its suitability for long-term studies, local sodium environments in sodium/sodium ion cells based on silicon carbonitride and hard carbon materials are tracked for up to 49 cycles (228.5?h). The formation of dendrites as well as the decay of a secondary metallic sodium species is observed, and local structures are analyzed up to the point of capacity degradation and cell failure. Initial points of cell breakdown are reflected in the NMR data by characteristic changes in signal intensities, whereas the degradation of the cells is reflected by a cease to periodic signal intensity fluctuations. Meanwhile, ex situ 23Na NMR spectra of the deactivated cells reveal a complex range of environments for sodium ions. author: - first_name: Sonja full_name: Egert, Sonja last_name: Egert - first_name: Renuka full_name: Remesh, Renuka last_name: Remesh - first_name: Agatha Clarissa full_name: Jusdi, Agatha Clarissa last_name: Jusdi - first_name: Yushi full_name: Sugawara, Yushi last_name: Sugawara - first_name: Konstantin full_name: Schutjajew, Konstantin last_name: Schutjajew - first_name: Martin full_name: Oschatz, Martin last_name: Oschatz - first_name: Gerd full_name: Buntkowsky, Gerd last_name: Buntkowsky - first_name: Torsten full_name: Gutmann, Torsten id: '118165' last_name: Gutmann citation: ama: Egert S, Remesh R, Jusdi AC, et al.

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.

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" article_type: original author: - first_name: 'Kim ' full_name: 'Baraka, Kim ' last_name: Baraka - first_name: Ifrah full_name: Idrees, Ifrah last_name: Idrees - first_name: Taylor Kessler full_name: Faulkner, Taylor Kessler last_name: Faulkner - first_name: Erdem full_name: Biyik, Erdem last_name: Biyik - first_name: Serena full_name: Booth, Serena last_name: Booth - first_name: Mohamed full_name: Chetouani, Mohamed last_name: Chetouani - first_name: Daniel H. full_name: Grollman, Daniel H. last_name: Grollman - first_name: Akanksha full_name: Saran, Akanksha last_name: Saran - first_name: Emmanuel full_name: Senft, Emmanuel last_name: Senft - first_name: Silvia full_name: Tulli, Silvia last_name: Tulli - first_name: Anna-Lisa full_name: Vollmer, Anna-Lisa last_name: Vollmer - first_name: Antonio full_name: Andriella, Antonio last_name: Andriella - first_name: Helen full_name: Beierling, Helen last_name: Beierling - first_name: Tiffany full_name: Horter, Tiffany last_name: Horter - first_name: Jens full_name: Kober, Jens last_name: Kober - first_name: Isaac full_name: Sheidlower, Isaac last_name: Sheidlower - first_name: Matthew E. full_name: Taylor, Matthew E. last_name: Taylor - first_name: Sanne full_name: van Waveren, Sanne last_name: van Waveren - first_name: Xuesu full_name: Xiao, Xuesu last_name: Xiao citation: ama: 'Baraka K, Idrees I, Faulkner TK, 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. article_number: '27' article_type: original author: - first_name: Tilo full_name: Böhmann, Tilo last_name: Böhmann - first_name: Angela full_name: Roth, Angela last_name: Roth - first_name: Gerhard full_name: Satzger, Gerhard last_name: Satzger - first_name: Carina full_name: Benz, Carina last_name: Benz - first_name: Daniel full_name: Beverungen, Daniel last_name: Beverungen - first_name: Andreas full_name: Boes, Andreas last_name: Boes - first_name: Christoph full_name: Breidbach, Christoph last_name: Breidbach - first_name: Martin full_name: Gersch, Martin last_name: Gersch - first_name: Gerhard full_name: Gudergan, Gerhard last_name: Gudergan - first_name: Jens full_name: Hogreve, Jens last_name: Hogreve - first_name: Christian full_name: Kurtz, Christian last_name: Kurtz - first_name: Barbara full_name: Langes, Barbara last_name: Langes - first_name: Jan Marco full_name: Leimeister, Jan Marco last_name: Leimeister - first_name: Tom full_name: Lewandowski, Tom last_name: Lewandowski - first_name: Thomas full_name: Meiren, Thomas last_name: Meiren - first_name: Rainer full_name: Nägele, Rainer last_name: Nägele - first_name: Stefanie full_name: Paluch, Stefanie last_name: Paluch - first_name: Christoph full_name: Peters, Christoph last_name: Peters - first_name: Jens full_name: Poeppelbuss, Jens last_name: Poeppelbuss - first_name: Susanne full_name: Robra-Bissantz, Susanne last_name: Robra-Bissantz - first_name: Carsten full_name: Schultz, Carsten last_name: Schultz - first_name: Jan H. full_name: Schumann, Jan H. last_name: Schumann - first_name: Jochen full_name: Wirtz, Jochen last_name: Wirtz - first_name: Nancy V. full_name: Wünderlich, Nancy V. last_name: Wünderlich citation: ama: 'Böhmann T, Roth A, Satzger G, et al.

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. article_number: '1053' article_type: original author: - first_name: Paul full_name: Steinmeier, Paul last_name: Steinmeier - first_name: Kay-Peter full_name: Hoyer, Kay-Peter last_name: Hoyer - first_name: Nelson Filipe full_name: Lopes Dias, Nelson Filipe last_name: Lopes Dias - first_name: Reiner full_name: Zielke, Reiner last_name: Zielke - first_name: Wolfgang full_name: Tillmann, Wolfgang last_name: Tillmann - first_name: Mirko full_name: Schaper, Mirko last_name: Schaper citation: ama: Steinmeier P, Hoyer K-P, Lopes Dias NF, Zielke R, Tillmann W, Schaper M.

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. citation: ama: Tischendorf R, Massopo O, Schmid H-J, et al., eds.

However, these systems are relevant for prospective buyers to find a trustworthy seller. This observation applies especially to short-lived business relationships where fulfilling the performance promise is subject to a high degree of uncertainty. 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. Depending on the market conditions and business context, the perceived value of the proposed system varies. author: - first_name: Simon full_name: Hemmrich, Simon id: '83557' last_name: Hemmrich - first_name: Jannika Marie full_name: Schäfer, Jannika Marie id: '74374' last_name: Schäfer - first_name: Philipp full_name: Hansmeier, Philipp id: '55603' last_name: Hansmeier - first_name: Daniel full_name: Beverungen, Daniel id: '59677' last_name: Beverungen citation: ama: 'Hemmrich S, Schäfer JM, Hansmeier P, Beverungen D.

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. article_type: original author: - first_name: Sarah full_name: Meusel, Sarah id: '56091' last_name: Meusel - first_name: Lukas full_name: Müller, Lukas id: '83570' last_name: Müller - first_name: Jonitta full_name: Jesuthasan, Jonitta id: '94539' last_name: Jesuthasan citation: ama: Meusel S, Müller L, Jesuthasan J.

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.

However, previous research argued that different fairness criteria are often incompatible. In hiring, AI is used to assess and rank applicants according to their fit for vacant positions. However, various types of bias also exist for AI-based algorithms (e.g., using biased historical data). To reduce AI’s bias and thereby unfair treatment, we conducted a systematic literature review to identify suitable strategies for the context of hiring. We identified nine fundamental articles in this context and extracted four types of approaches to address unfairness in AI, namely pre-process, in-process, post-process, and feature selection. Based on our findings, we (a) derived a research agenda for future studies and (b) proposed strategies for practitioners who design and develop AIs for hiring purposes. author: - first_name: Jonas full_name: Rieskamp, Jonas id: '77643' last_name: Rieskamp - first_name: Lennart full_name: Hofeditz, Lennart last_name: Hofeditz - first_name: Milad full_name: Mirbabaie, Milad id: '88691' last_name: Mirbabaie - first_name: Stefan full_name: Stieglitz, Stefan last_name: Stieglitz citation: ama: 'Rieskamp J, Hofeditz L, Mirbabaie M, Stieglitz S.

In\r\nour theoretical model, physicians are faced with a heterogeneous patient population, in which patients\r\nsystematically vary with regard to both their responsiveness to the provided quality of care and their\r\nstate of health. We test the behavioral predictions derived from this model in a controlled laboratory\r\nexperiment. In line with the model, we observe that competition significantly improves patient benefits\r\nas long as patients are able to respond to the quality provided. For those patients, who are not able\r\nto choose a physician, competition even decreases the patient benefit compared to a situation without\r\ncompetition. This decrease is in contrast to our theoretical prediction implying no change in benefits for\r\npassive patients. Deviations from patient-optimal treatment are highest for passive patients in need of\r\na low quantity of medical services. With repetition, both, the positive effects of competition for active\r\npatients as well as the negative effects of competition for passive patients become more pronounced. Our\r\nresults imply that competition can not only improve but also worsen patient outcome and that patients’\r\nresponsiveness to quality is decisive." article_type: original author: - first_name: Jeannette full_name: Brosig-Koch, Jeannette last_name: Brosig-Koch - first_name: Burkhard full_name: Hehenkamp, Burkhard id: '37339' last_name: Hehenkamp - first_name: Johanna full_name: Kokot, Johanna last_name: Kokot citation: ama: Brosig-Koch J, Hehenkamp B, Kokot J.

The cell set-up is suitable for using powder electrode materials. Reproducibility of our cell assembly is analyzed by preparing two cells containing hard carbon (HC) powder as working electrode and sodium metal as reference electrode. Electrochemical storage properties of HC powder electrode derived from carbonization of sustainable cellulose are studied by ssNMR. 23Na in-situ ssNMR monitors the sodiation/desodiation of a Na{\textbar}NaPF6{\textbar}HC cell (cell 1) over a period of 22?days, showing high cell stability. After the galvanostatic process, the HC powder material is investigated by high resolution 23Na ex-situ MAS NMR. The formation of ionic sodium species in different chemical environments is obtained. Subsequently, a second Na{\textbar}NaPF6{\textbar}HC cell (cell 2) is sodiated for 11?days achieving a capacity of 220?mAh/g. 23Na ex-situ MAS NMR measurements of the HC powder material extracted from this cell clearly indicate the presence of quasi-metallic sodium species next to ionic sodium species. This observation of quasi-metallic sodium species is discussed in terms of the achieved capacity of the cell as well as of side reactions of sodium in this electrode material. author: - first_name: Edina full_name: Šić, Edina last_name: Šić - first_name: Konstantin full_name: Schutjajew, Konstantin last_name: Schutjajew - first_name: Ulrich full_name: Haagen, Ulrich last_name: Haagen - first_name: Hergen full_name: Breitzke, Hergen last_name: Breitzke - first_name: Martin full_name: Oschatz, Martin last_name: Oschatz - first_name: Gerd full_name: Buntkowsky, Gerd last_name: Buntkowsky - first_name: Torsten full_name: Gutmann, Torsten id: '118165' last_name: Gutmann citation: ama: 'Šić E, Schutjajew K, Haagen U, et al.
