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."}],"language":[{"iso":"eng"}],"article_number":"37","main_file_link":[{"open_access":"1","url":"https://link.springer.com/content/pdf/10.1007/s12525-026-00889-w.pdf"}],"doi":"10.1007/s12525-026-00889-w","author":[{"full_name":"Beverungen, Daniel","first_name":"Daniel","last_name":"Beverungen"},{"last_name":"Poeppelbuss","first_name":"Jens","full_name":"Poeppelbuss, Jens"},{"full_name":"Hemmrich, Simon","last_name":"Hemmrich","first_name":"Simon"},{"full_name":"Iqbal, Taskeen","last_name":"Iqbal","first_name":"Taskeen"}],"publication_identifier":{"issn":["1019-6781","1422-8890"]},"title":"Service through communication—Conceptualizing service systems with Luhmann’s systems theory","year":"2026","article_type":"original","intvolume":"        36","publication_status":"published","date_updated":"2026-06-11T13:18:09Z","oa":"1","citation":{"bibtex":"@article{Beverungen_Poeppelbuss_Hemmrich_Iqbal_2026, title={Service through communication—Conceptualizing service systems with Luhmann’s systems theory}, volume={36}, DOI={<a href=\"https://doi.org/10.1007/s12525-026-00889-w\">10.1007/s12525-026-00889-w</a>}, number={137}, journal={Electronic Markets}, publisher={Springer Science and Business Media LLC}, author={Beverungen, Daniel and Poeppelbuss, Jens and Hemmrich, Simon and Iqbal, Taskeen}, year={2026} }","ama":"Beverungen D, Poeppelbuss J, Hemmrich S, Iqbal T.

Recently, it has been experimentally demonstrated that photonic platforms based on Gaussian boson sampling (GBS) are capable of performing these simulations. However, whether an actual GBS approach is required depends on the molecule under investigation. To develop a better understanding on the requirements for simulating vibronic spectra, we explore connections between theoretical approximations in physical chemistry and their photonic counterparts. Mapping these approximations into photonics, we show that for certain molecules the GBS approach is unnecessary. We place special emphasis on the linear coupling approximation, which in photonics corresponds to sampling from multiple coherent states. By implementing this approach in experiments, we demonstrate improved similarities over previously reported GBS results for formic acid and identify the particular attributes that a molecule must exhibit for this, and other approximations, to be valid. These results highlight the importance in forming deeper connections between traditional methods and photonic approaches.","lang":"eng"}],"related_material":{"link":[{"url":"https://doi.org/10.5281/zenodo.18969354","relation":"research_data"}]},"date_created":"2026-06-12T08:14:35Z","department":[{"_id":"288"},{"_id":"623"},{"_id":"15"}],"type":"journal_article","author":[{"id":"73665","first_name":"Jan-Lucas","orcid":"0009-0008-6524-7684","last_name":"Eickmann","full_name":"Eickmann, Jan-Lucas"},{"full_name":"Luo, Kai-Hong","last_name":"Luo","first_name":"Kai-Hong","orcid":"0000-0003-1008-4976","id":"36389"},{"full_name":"Roiz, Mikhail","last_name":"Roiz","first_name":"Mikhail","id":"114114"},{"full_name":"Lammers, Jonas","first_name":"Jonas","last_name":"Lammers"},{"full_name":"Atzeni, Simone","last_name":"Atzeni","first_name":"Simone","id":"98338"},{"last_name":"Pandey","first_name":"Cheeranjiv","full_name":"Pandey, Cheeranjiv"},{"last_name":"Lütkewitte","first_name":"Florian","full_name":"Lütkewitte, Florian"},{"full_name":"Shirazi, Reza G.","first_name":"Reza G.","last_name":"Shirazi"},{"full_name":"Schlue, Fabian","first_name":"Fabian","last_name":"Schlue","id":"63579"},{"id":"27150","last_name":"Brecht","first_name":"Benjamin","orcid":"0000-0003-4140-0556 ","full_name":"Brecht, Benjamin"},{"last_name":"Rybkin","first_name":"Vladimir V.","full_name":"Rybkin, Vladimir V."},{"id":"42777","last_name":"Stefszky","first_name":"Michael","full_name":"Stefszky, Michael"},{"first_name":"Christine","last_name":"Silberhorn","full_name":"Silberhorn, Christine","id":"26263"}],"publication_identifier":{"issn":["2056-6387"]},"title":"Bridging chemistry and Gaussian boson sampling: a photonic hierarchy of approximations for molecular vibronic spectra","year":"2026","article_type":"original","intvolume":"        12","publication_status":"published","date_updated":"2026-06-12T08:28:02Z","language":[{"iso":"eng"}],"article_number":"89","main_file_link":[{"url":"https://www.nature.com/articles/s41534-026-01250-x.pdf","open_access":"1"}],"doi":"10.1038/s41534-026-01250-x"},{"year":"2026","title":"Developing AI Literacy of Novice Adult Learners Outside of Formal Education Settings – a Prototype","author":[{"id":"74589","last_name":"Rinkowski","first_name":"Alexander","full_name":"Rinkowski, Alexander"},{"first_name":"Dennis","last_name":"Kundisch","full_name":"Kundisch, Dennis","id":"21117"}],"date_updated":"2026-06-12T08:52:53Z","publication_status":"epub_ahead","intvolume":"     16607","series_title":"Lecture Notes in Computer Science","language":[{"iso":"eng"}],"doi":"10.1007/978-3-032-28570-6_32","publication":"Design for Better Futures: Beyond the Science of the Artificial.

We employ a two-phase solution framework: in phase 1, we solve the Charging Location and Electric Vehicle Scheduling Problem to generate vehicle schedules that are feasible for electric operation; in phase 2, these schedules serve as input to a multi-period transition planning model that minimizes the total cost of ownership while determining fleet replacement and charging infrastructure deployment. Our experiments show that schedules obtained from solving the integrated charging location and vehicle scheduling problem significantly outperform traditional methods, resulting in lower total cost of ownership. Additionally, transition plans reduce local emissions by up to 85% compared to a diesel-only scenario. We find that vehicle rotations with long distances and sufficient idle time are prioritized for electrification, enabling earlier emission reductions and cost savings. This highlights the importance of adopting vehicle scheduling tailored for electric buses, rather than relying on legacy diesel schedules.","lang":"eng"}],"file":[{"file_id":"65858","success":1,"content_type":"application/pdf","file_name":"ELSEVIER ARTICLE.pdf","file_size":1379145,"access_level":"closed","relation":"main_file","date_updated":"2026-06-13T06:45:51Z","date_created":"2026-06-13T06:45:51Z","creator":"schryen"}],"date_created":"2026-06-13T06:38:22Z","keyword":["Electric bus","Multi-period planning","Electric vehicle scheduling","Charging infrastructure","Fleet replacement"],"type":"journal_article","department":[{"_id":"277"}],"title":"Impact of vehicle scheduling and strategic transition planning on zero-emission bus systems","year":"2026","author":[{"full_name":"Stumpe, Miriam","last_name":"Stumpe","first_name":"Miriam","id":"64135"},{"first_name":"David","last_name":"Rößler-von Saß","full_name":"Rößler-von Saß, David"},{"full_name":"Kliewer, Natalia","last_name":"Kliewer","first_name":"Natalia"},{"full_name":"Schryen, Guido","last_name":"Schryen","first_name":"Guido","id":"72850"}],"publication_identifier":{"issn":["2590-1982"]},"publication_status":"published","date_updated":"2026-06-13T06:46:16Z","article_type":"original","intvolume":"        38","article_number":"102008","language":[{"iso":"eng"}],"doi":"10.1016/j.trip.2026.102008"},{"file_date_updated":"2026-06-13T06:49:02Z","citation":{"bibtex":"@article{Paré_Wagner_Tate_Schryen_Templier_2026, title={Theorising Forward: Positioning Deductive Elaboration in the Information Systems Research Repertoire}, volume={35}, DOI={<a href=\"https://doi.org/10.1080/0960085x.2025.2550403\">10.1080/0960085x.2025.2550403</a>}, number={3}, journal={European Journal of Information Systems}, publisher={Informa UK Limited}, author={Paré, Guy and Wagner, Gerit and Tate, Mary and Schryen, Guido and Templier, Mathieu}, year={2026}, pages={555–579} }","ama":"Paré G, Wagner G, Tate M, Schryen G, Templier M.

This study examines the role of\r\nproblem-solving heuristics among 73 sixth-grade students in a German secondary\r\nschool (Gesamtschule). Specifically, we focus on the empirical relationship between\r\nthe occurrence of heuristics, their suitability, and application, as well as their contribution\r\nto problem-solving success. To this end, we developed a heuristic training that\r\nintroduced strategy keys (heuristic aid cards) accompanied by explanatory videos. By\r\nleveraging variations in the successful application of the heuristics between students\r\nand across multiple sessions (73 students in 4 training situations and 3 problems\r\nin a final test), we discover from regression models with student and task-fixed effects\r\nthat a successful use of heuristics (i.e., an heuristic occurred, that heuristic had\r\na high suitability regarding the problem, and it was applied correctly) leads to more\r\nsuccessful mathematical problem solving. Regarding the underlying mechanism, we\r\nfind that all dimensions of heuristic use (occurrence, suitability, and application\r\nof heuristics) are positively related to problem-solving success. When comparing\r\nthe predictive capacity of all three aspects, we identified the correct application of\r\nheuristics as particularly conducive for better problem-solving success. In comparing\r\nthe group of students with high to those with low initial math competence, we find no significant differences in the relationship between heuristic use and problemsolving\r\nsuccess across achievement groups. Our results emphasize the crucial role\r\nof heuristic application in mathematical problem solving, which generally benefits\r\nstudents regardless of their overall math competence.","lang":"eng"}],"issue":"6","publication":"Journal für Mathematik-Didaktik","type":"journal_article","department":[{"_id":"97"}],"file":[{"access_level":"closed","file_size":1766182,"file_name":"2026_JMD_Herold-Blasius et al_Dimensions of heuristic use.pdf","date_updated":"2026-06-15T10:03:48Z","relation":"main_file","success":1,"content_type":"application/pdf","file_id":"65866","creator":"rheroldb","date_created":"2026-06-15T10:03:48Z"}],"date_created":"2026-06-15T10:08:04Z"}]
