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.","lang":"eng"}],"keyword":["Continuous Value Shaping","Service Systems Engineering","Service Science","Public Sector","Service Innovation"],"language":[{"iso":"eng"}],"quality_controlled":"1","year":"2026","publisher":"Association for Information Systems (AIS), IEEE Computer Society Press, University of Hawaii (Manoa)","date_created":"2025-09-16T13:55:52Z","title":"From Engineering to Shaping: A Multiple Case Study on Advancing Service Systems Engineering through Continuous Value Shaping"},{"quality_controlled":"1","issue":"1","year":"2026","publisher":"Springer Science and Business Media LLC","date_created":"2026-04-21T13:13:02Z","title":"Service through communication—Conceptualizing service systems with Luhmann’s systems theory","publication":"Electronic Markets","abstract":[{"text":"Service research has evolved into an interdisciplinary research field that bridges diverse disciplines, including information systems (IS) and marketing. 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.","lang":"eng"}],"file":[{"success":1,"relation":"main_file","content_type":"application/pdf","file_size":2793039,"file_name":"Service is Communication - EM Paper.pdf","file_id":"65477","access_level":"closed","date_updated":"2026-04-21T13:14:30Z","date_created":"2026-04-21T13:14:30Z","creator":"dabe"}],"keyword":["Service system","Service ecosystem","Systems theory","Service research"],"ddc":["380"],"language":[{"iso":"eng"}],"has_accepted_license":"1","publication_identifier":{"issn":["1019-6781","1422-8890"]},"publication_status":"published","intvolume":" 36","jel":["L80"],"citation":{"ieee":"D.

E. Moore, C. D. Broad, and J. E. McTaggart. He received his BA in 1924, after which he worked for five years at the National Institute of Industrial Psychology. From 1929 to 1934, Wisdom was a Lecturer in the department of logic and metaphysics at the University of St Andrews and a colleague of G. F. Stout. After the publication of his book Interpretation and Analysis (1931) and five articles on “Logical Constructions” in Mind (1931–3), Wisdom became a Lecturer in Moral Sciences in Cambridge and a Fellow of Trinity College. This gave him the opportunity to gain first-hand knowledge of Wittgenstein’s philosophy. Since nothing by Wittgenstein but Tractatus appeared in print for decades, Wisdom’s publications of these years were—mistakenly—read as portents of the new ideas of Wittgenstein himself. The publication of Wittgenstein’s Philosophical Investigations in 1953 brought with it, among other things, the fall of Wisdom’s popularity.

The paper was unusually critical of Wittgenstein. It put the Cambridge analytic philosophy of Moore and Russell in a sharp opposition to the positivist philosophy of the Vienna Circle, in which Stebbing included Wittgenstein. Whereas the positivists were interested in analysing language, the Cambridge realists were analysing facts. To be more explicit, the analytic philosophers were engaged in directional analysis, which seeks to illuminate (to elucidate) the multiplicity of the analysed facts. In contrast, positivists aimed at a final analysis that proves that there are simples. Stebbing’s sympathies were clearly on the side of the Cambridge realists. The important implication of Stebbing’s paper was that it urged Wittgenstein to change the style of his philosophy, abandoning those points which allegedly connected him with the Vienna Circle."}],"editor":[{"last_name":"Khani ","full_name":"Khani , Ali Hossein ","first_name":"Ali Hossein "},{"first_name":"Gary ","full_name":"Kemp , Gary ","last_name":"Kemp "}],"type":"book_chapter","publication":"Wittgenstein and Other Philosophers: His Influence on Historical and Contemporary Analytic Philosophers, vol.

While a variety of disciplines are developing new approaches to drive service innovation, this is primarily done in isolation and generates only fragmented solutions.

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.

We contextualize our resulting typology in the\r\nhealth service context and integrate extant literature on technology-enabled service, AI\r\nconsciousness, and AI ethics into the narrative.\r\n\r\nFindings: This study provides a unique theoretical contribution to service research in the form of\r\na Type IV theory. It enables future service researchers to apprehend, explain, and predict how\r\nfunctionally conscious AI in service might unfold.\r\n\r\nOriginality: An increasingly prolific public discourse acknowledges that conscious AI systems\r\nmay emerge. Against this backdrop, this study aims to systematically explore a question that is\r\nperhaps the most critical and timely, but also inherently speculative, in relation to AI in service\r\nresearch by introducing much-needed theory and terminology.\r\n\r\nPractical implications: The ethical use of conscious AI in service could emerge as a distinct\r\ncompetitive advantage in the future. Achieving this outcome involves speculative yet actionable\r\nrecommendations that include training, guiding, and controlling how humans engage with such\r\nsystems, developing appropriate wellbeing protocols for functionally conscious AI systems, and\r\nestablishing AI rights and governance frameworks.","lang":"eng"}],"type":"journal_article","publication":"Journal of Service Management","file_date_updated":"2025-11-10T10:20:48Z","language":[{"iso":"eng"}],"article_type":"original","ddc":["380"],"keyword":["AI","AI consciousness","AI ethics","service systems"],"user_id":"59677","department":[{"_id":"195"}],"_id":"61410","citation":{"ama":"Breidbach C, Lars-Erik CF, Maglio P, Beverungen D, Wirtz J, Twigg A.

However, in academic teacher education programmes often use assessment formats that are not well aligned with the demands of teachers' actual professional practice. Performance-based assessments can offer an alternative, for example in the form of role-play-based simulations with trained actors representing typical professional activities in environments of reduced complexity. We have developed such a performance-based assessment format for physics teacher education, analogous to the Objective Structured Teaching Examinations (OSTE) approach used in medical education. The OSTE prototype consists of seven short simulative assessments, reflecting four areas of competence (Instruction, Assessment, Pedagogy and Innovation) that form a 90-minute examination course. In order to investigate prospective physics teachers' perceptions of such an assessment format in terms of its suitability as a summative examination procedure, we piloted the OSTE prototype with N = 34 physics student teachers from three German universities using short questionnaires. The results show that participants perceived the OSTE prototype as authentic and relevant, but they also highlight the need for adequate new learning opportunities to prepare for such simulative examinations to be integrated into teacher education programmes."}],"date_created":"2025-12-03T08:43:26Z","author":[{"id":"4245","full_name":"Vogelsang, Christoph","last_name":"Vogelsang","orcid":"0000-0002-5804-1855","first_name":"Christoph"},{"last_name":"Grotegut","id":"34280","full_name":"Grotegut, Lea","first_name":"Lea"},{"id":"89529","full_name":"Wotschel, Philipp","last_name":"Wotschel","first_name":"Philipp"},{"first_name":"Thomas","full_name":"Janzen, Thomas","id":"89329","last_name":"Janzen","orcid":"0009-0003-1941-166X"}],"date_updated":"2025-12-03T08:56:29Z","conference":{"name":"ESERA 2025 Conference","start_date":"2025-08-25","end_date":"2025-08-30","location":"Copenhagen"},"title":"Prospective Physics Teachers' Perceptions of an Objective Structured Teaching Examination (OSTE)","quality_controlled":"1","citation":{"ieee":"C.

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.

These model-free DRL approaches are more flexible but typically learn tabula rasa, i.e., disregard existing understanding of networks, services, and their coordination. \r\n\r\nInstead, we propose FutureCoord, a novel model-based AI approach that leverages existing understanding of networks and services for more efficient and effective coordination without time-intensive training. FutureCoord combines Monte Carlo Tree Search with a stochastic traffic model. This allows FutureCoord to estimate the impact of future incoming traffic and effectively optimize long-term effects, taking fluctuating demand and Quality of Service (QoS) requirements into account. Our extensive evaluation based on real-world network topologies, services, and traffic traces indicates that FutureCoord clearly outperforms state-of-the-art model-free and model-based approaches with up to 51% higher flow success ratios."}],"language":[{"iso":"eng"}],"ddc":["004"],"keyword":["network management","service management","AI","Monte Carlo Tree Search","model-based","QoS"],"quality_controlled":"1","year":"2022","date_created":"2022-01-11T08:43:26Z","publisher":"IEEE","title":"Use What You Know: Network and Service Coordination Beyond Certainty","type":"conference","status":"public","user_id":"35343","department":[{"_id":"75"}],"project":[{"name":"SFB 901: SFB 901","_id":"1"},{"name":"SFB 901 - C: SFB 901 - Project Area C","_id":"4"},{"name":"SFB 901 - C4: SFB 901 - Subproject C4","_id":"16"}],"_id":"29220","file_date_updated":"2022-01-11T08:39:57Z","has_accepted_license":"1","citation":{"ama":"Werner S, Schneider SB, Karl H.

While knowledge is acquired during studies, the preparatory service, which takes place predominantly in schools, serves to acquire practical competencies, which include reference to theoretical knowledge and the development of experience-based knowledge. The measures to contain the corona pandemic not only change everyday school life but also have an impact on the competence development of prospective teachers in preparatory service, who have to carry out their professional training under changed boundary conditions. Among other things, the current boundary conditions can make regular training more difficult due to a lack of or limited practical experience, which then can contribute to an increased feeling of stress among prospective teachers. This article refers to data from an explorative interview study with prospective teachers from North Rhine-Westphalia (N = 19) who completed their preparatory service during the pandemic in the year 2020. It is discussed which stress factors can occur in connection with the corona pandemic during preparatory service and to what extent prospective teachers experience themselves as stressed during their preparatory service against the background of the current boundary conditions as a result of the corona pandemic.","lang":"eng"}],"language":[{"iso":"ger"}],"keyword":["Corona-Pandemie","Lehramtsanwärter:innen","Lehrer:innenausbildung","Professionalisierung","Vorbereitungsdienst / corona pandemic","prospective teachers","teacher training","professionalization","preparatory service"]},{"language":[{"iso":"eng"}],"keyword":["Inclusion","basic needs","pre-service teacher training","interest","self-efficacy"],"publication":"PATT39 - PATT on the Edge Technology, Innovation and Education","abstract":[{"lang":"eng","text":"Theoretical approaches to the transformation towards an inclusive educational system in Germany mostly agree on the involvement of developmental tasks in subject related research (Hinz, 2011). The common understanding of inclusion as a process geared towards equal participation of all children (Booth, 2012) requires a reflexive questioning of established values, attitudes and practices in order to develop inclusive subject related research, teacher training and teaching and learning (Pech & Schomaker, 2013). Among other things, this results in consequences for the design of pre- service teacher training. To a large extent, teacher education is driven by the promotion of central competencies, interests and self-efficacy (Baumert & Kunter, 2011). It aims towards the development and realisation of inclusive interdisciplinary science and social studies (‘Sachunterricht’) in primary education (Moser, 2018). In conjunction with largely acknowledged constructivist approaches to teaching and learning (Möller, 2001), the development of personality, the consideration of basic needs (Deci & Ryan, 1993) and promotion of individual potentials are repeatedly fundamentally represented in subject related and pedagogical considerations (Feuser, 1989; GDSU, 2013). Therefore, the aforementioned constructivist approach is connected to several certain key paradigms for teaching and learning processes (e.g., Vygotskij, 1978; Posner et al., 1982; van de Pol et al., 2010). In this regard, the nature of primary school students’ basic needs have empirically not been sufficiently studied yet. Theoretical frameworks from motivational psychology (Deci & Ryan, 1993) do not explicitly address how individual needs differ and how the diversity of needs can be included in joint-learning, multi-perspective technology education classes. The research project the present paper is part of aims to develop a research-based concept for the professionalisation of pre-service teachers in a seminar course. Therefore, the promotion of the pre- service teachers’ interests and self-efficacy expectations have been assessed in a pre-post research design with a control group visiting another course not related to technology education and inclusion. The present paper describes and discusses first results of the project and will give an outlook on subsequent developmental tasks."}],"date_created":"2023-01-25T15:13:45Z","title":"How to enable pre-service teachers to design technological teaching and learning inclusively? – On the nature and consideration of basic needs in teacher training","quality_controlled":"1","year":"2022","department":[{"_id":"588"}],"user_id":"71764","series_title":"PATT Proceedings","_id":"40046","type":"conference","status":"public","editor":[{"first_name":"David","full_name":"Gill, David","last_name":"Gill"},{"first_name":"Jim","last_name":"Tuff","full_name":"Tuff, Jim"},{"first_name":"Thomas","full_name":"Kennedy, Thomas","last_name":"Kennedy"},{"last_name":"Pendergast","full_name":"Pendergast, Shawn","first_name":"Shawn"},{"first_name":"Sana","last_name":"Jamil","full_name":"Jamil, Sana"}],"author":[{"first_name":"Franz","full_name":"Schröer, Franz","id":"71764","last_name":"Schröer"},{"last_name":"Tenberge","full_name":"Tenberge, Claudia","id":"67302","first_name":"Claudia"}],"date_updated":"2023-01-25T15:13:57Z","conference":{"location":"St. John’s, Newfoundland and Labrador, Canada","end_date":"2022-06-24","start_date":"2022-06-21","name":"PATT39 - PATT on the Edge Technology, Innovation and Education"},"main_file_link":[{"url":"https://research.edgehill.ac.uk/ws/portalfiles/portal/50821651/patt39_proceedings_june_17_2022.pdf"}],"publication_identifier":{"unknown":["https://research.edgehill.ac.uk/ws/portalfiles/portal/50821651/patt39_proceedings_june_17_2022.pdf"]},"publication_status":"published","page":"49-57","citation":{"mla":"Schröer, Franz, and Claudia Tenberge. “How to Enable Pre-Service Teachers to Design Technological Teaching and Learning Inclusively? – On the Nature and Consideration of Basic Needs in Teacher Training.” PATT39 - PATT on the Edge Technology, Innovation and Education, edited by David Gill et al., 2022, pp. 49–57.","short":"F.

Providing these services requires online coordination including scaling the service, placing instance of all components in the network, scheduling traffic to these instances, and routing traffic through the network. Optimized service coordination is still a hard problem due to many influencing factors such as rapidly arriving user demands and limited node and link capacity. Existing approaches to solve the problem are often built on rigid models and assumptions, tailored to specific scenarios. If the scenario changes and the assumptions no longer hold, they easily break and require manual adjustments by experts. Novel self-learning approaches using deep reinforcement learning (DRL) are promising but still have limitations as they only address simplified versions of the problem and are typically centralized and thus do not scale to practical large-scale networks.\r\n\r\nTo address these issues, we propose a distributed self-learning service coordination approach using DRL. After centralized training, we deploy a distributed DRL agent at each node in the network, making fast coordination decisions locally in parallel with the other nodes. Each agent only observes its direct neighbors and does not need global knowledge. Hence, our approach scales independently from the size of the network. In our extensive evaluation using real-world network topologies and traffic traces, we show that our proposed approach outperforms a state-of-the-art conventional heuristic as well as a centralized DRL approach (60% higher throughput on average) while requiring less time per online decision (1 ms)."}],"publication":"IEEE International Conference on Distributed Computing Systems (ICDCS)","language":[{"iso":"eng"}],"keyword":["network management","service management","coordination","reinforcement learning","distributed"],"ddc":["000"],"year":"2021","title":"Distributed Online Service Coordination Using Deep Reinforcement Learning","date_created":"2021-03-18T17:15:47Z","publisher":"IEEE","status":"public","type":"conference","file_date_updated":"2021-03-18T17:12:56Z","department":[{"_id":"75"}],"user_id":"35343","_id":"21543","project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Project Area C","_id":"4"},{"_id":"16","name":"SFB 901 - Subproject C4"}],"citation":{"bibtex":"@inproceedings{Schneider_Qarawlus_Karl_2021, title={Distributed Online Service Coordination Using Deep Reinforcement Learning}, booktitle={IEEE International Conference on Distributed Computing Systems (ICDCS)}, publisher={IEEE}, author={Schneider, Stefan Balthasar and Qarawlus, Haydar and Karl, Holger}, year={2021} }","short":"S.B.

Rather than defining a complex model or an algorithm on how to achieve an objective, our model-free approach adapts to various objectives and traffic patterns. An agent is trained offline without expert knowledge and then applied online with minimal overhead. Compared to a state-of-the-art heuristic, DeepCoord significantly improves flow throughput (up to 76%) and overall network utility (more than 2x) on realworld network topologies and traffic traces. It also supports optimizing multiple, possibly competing objectives, learns to respect QoS requirements, generalizes to scenarios with unseen, stochastic traffic, and scales to large real-world networks.
