To identify existing implications of GenAI for design-oriented research in IS, we report results from an integrative literature review of recent DSR publications in leading IS outlets. Thereby, we synthesize five major theoretical challenges that arise when using GenAI in DSR projects: (1) an obscure composition of the artifact, (2) an opaque contextualization of the LLM, (3) a fragile internal consistency of the artifact, (4) a rapid erosion of prescriptive knowledge, and (5) missing methodological guidance. We investigate these challenges and conceptualize a set of three guidelines that inform DSR in the rising era of GenAI. These guidelines support researchers in designing and justifying GenAI-related DSR processes and in precisely articulating the theoretical grounding of their design decisions and evaluation strategies."}],"publication":"Lecture Notes in Computer Science","type":"conference","department":[{"_id":"195"}],"date_created":"2026-06-03T09:20:18Z"},{"doi":"10.1007/s40573-026-00194-1","alternative_title":["Analyse der Modellierungsprozesse von Grundschüler:innen zum Thema Löslichkeit"],"language":[{"iso":"ger"}],"date_updated":"2026-06-03T12:02:08Z","publication_status":"published","intvolume":"        32","year":"2026","title":"Modellieren und Denken im Diskontinuum","author":[{"id":"54277","full_name":"Elsner, Julia","first_name":"Julia","last_name":"Elsner"},{"id":"67302","full_name":"Tenberge, Claudia","last_name":"Tenberge","first_name":"Claudia"},{"id":"54823","first_name":"Sabine","last_name":"Fechner","orcid":"0000-0001-5645-5870","full_name":"Fechner, Sabine"}],"type":"journal_article","department":[{"_id":"386"},{"_id":"588"}],"date_created":"2025-12-08T09:33:10Z","issue":"1","publication":"Zeitschrift für Didaktik der Naturwissenschaften","user_id":"54277","volume":32,"page":"1-17","_id":"62957","status":"public","quality_controlled":"1","citation":{"mla":"Elsner, Julia, et al. “Modellieren und Denken im Diskontinuum.” <i>Zeitschrift für Didaktik der Naturwissenschaften</i>, vol. 32, no. 1, 2026, pp. 1–17, doi:<a href=\"https://doi.org/10.1007/s40573-026-00194-1\">10.1007/s40573-026-00194-1</a>.","ama":"Elsner J, Tenberge C, Fechner S.

The study aims to delineate desirable and undesirable digital futures to inform policy discourse and strategic planning. It begins with the outlining of the research basis and methodology, where it employs a methodological synthesis of the Scenario Development Technique from the UN Strategic Foresight Guide and STEEP Analysis. This approach integrates a macro environmental assessment of socio-cultural, technological, economic, environmental, and political dimensions to identify key drivers of change and differences. These are then mapped onto a two-by-two matrix defined by two primary axes. This combination enabled the development of four scenarios examining the impact of digital technologies across these dimensions. The scenarios diverge along two axes. The vertical axis represents the mode of societal organisation and political power (authoritarianism versus democracy). The horizontal axis represents the mode of governance and citizen engagement (representation versus participation). By contrasting these divergent paths, this paper provides a critical framework for analysing how digital technologies intersect with political will and socioeconomic structures."}],"date_created":"2026-06-04T20:14:20Z","type":"journal_article","department":[{"_id":"136"},{"_id":"11"}],"title":"The Futures of Digital Democracy: Four Scenarios","year":"2026","author":[{"id":"21863","first_name":"Christian","orcid":"0000-0003-0589-4579","last_name":"Fuchs","full_name":"Fuchs, Christian"},{"first_name":"Joel","last_name":"Museba","full_name":"Museba, Joel"},{"last_name":"Friesch","first_name":"Kevin","full_name":"Friesch, Kevin"}],"publication_identifier":{"issn":["2732-5121"]},"publication_status":"published","date_updated":"2026-06-04T20:17:42Z","intvolume":"         6","article_number":"49","language":[{"iso":"eng"}],"doi":"10.12688/openreseurope.22910.2"},{"has_accepted_license":"1","status":"public","volume":"Vol. 5  (2026)","ddc":["200"],"user_id":"95179","publisher":"LibreCat University","_id":"65585","page":"94-111","quality_controlled":"1","citation":{"ieee":"M.

Detailed experimental results from tensile tests on a representative SPR joint are presented, with local joint kinematics quantified using multiple complementary measurement methods (optical measurement, micrographs, in situ computer tomography). Furthermore, results of component tests are shown where the kinematics of the joints have been measured in the same manner. The experimental results are later used to calibrate simulation models for crash application which are used to simulate the specimen and component tests. The results of the investigation show that the local joint kinematic influences the failure behavior of the joint.

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."}],"_id":"65476","publisher":"Springer Science and Business Media LLC","ddc":["380"],"user_id":"59677","volume":36,"status":"public","jel":["L80"],"has_accepted_license":"1","oa":"1","file_date_updated":"2026-04-21T13:14:30Z","citation":{"mla":"Beverungen, Daniel, et al. “Service through Communication—Conceptualizing Service Systems with Luhmann’s Systems Theory.” <i>Electronic Markets</i>, vol. 36, no. 1, 37, Springer Science and Business Media LLC, 2026, doi:<a href=\"https://doi.org/10.1007/s12525-026-00889-w\">10.1007/s12525-026-00889-w</a>.","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.

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"}],"publication":"Journal für Mathematik-Didaktik","issue":"6","type":"journal_article","department":[{"_id":"97"}],"file":[{"date_created":"2026-06-15T10:03:48Z","creator":"rheroldb","file_id":"65866","content_type":"application/pdf","success":1,"relation":"main_file","date_updated":"2026-06-15T10:03:48Z","file_name":"2026_JMD_Herold-Blasius et al_Dimensions of heuristic use.pdf","access_level":"closed","file_size":1766182}],"date_created":"2026-06-15T10:08:04Z","has_accepted_license":"1","status":"public","user_id":"126182","ddc":["510"],"volume":47,"_id":"65865","quality_controlled":"1","file_date_updated":"2026-06-15T10:03:48Z","citation":{"bibtex":"@article{Herold-Blasius_Kleinschmidt_Ziller_2026, title={Dimensions of Heuristic Use in Mathematical Problem Solving: Evidence from Early Secondary School Students}, volume={47}, DOI={<a href=\"https://doi.org/10.1007/s13138-026-00270-6\">https://doi.org/10.1007/s13138-026-00270-6</a>}, number={6}, journal={Journal für Mathematik-Didaktik}, author={Herold-Blasius, Raja and Kleinschmidt, Hannah and Ziller, Conrad}, year={2026} }","ama":"Herold-Blasius R, Kleinschmidt H, Ziller C.

However, the necessary adaptation of the rivet-die combination to the respective material and thickness combinations requires a large number of specific tool sets, which significantly limits the process's flexibility. To overcome these limitations, the versatile self-piercing riveting (V-SPR) was developed, which features enhanced punch actuation in combination with a multi-range-capable rivet . In this context, the concept of a movable die was introduced, which enables an extended process window and adaptable joint formation. Kappe et al. presented initial studies demonstrating the potential of this approach . However, a detailed numerical understanding of the underlying mechanisms remains lacking. This paper presents a numerical analysis of V-SPR with a movable die using a finite element (FE) model. The model includes deformable rivets, sheet metal materials and a kinematically controlled die with adjustable movement. A parameter study was conducted to analyse the influence of die movement on the material flow of the rivet and sheets, as well as joint formation. The simulations were validated using selected experimental data. The goal is to compare the joint geometries achieved with fixed and moving dies and expand the process windows of VSPR. The results demonstrate that the movable-die concept significantly enhances the material flow of both the sheets and the rivet, resulting in a noticeably larger and more reliable interlock than what is achievable with V-SPR using a fixed die. The numerical analyses support the observations reported by Kappe et al. and extend them by providing a quantitative description of how die displacement influences the resulting interlock size. Moreover, the ability to precisely control the die movement makes it possible to join challenging sheet-metal combinations that are difficult to process with conventional setups, particularly in cases involving thicker sheet materials.","lang":"eng"}],"date_created":"2026-05-13T07:33:27Z","type":"journal_article","department":[{"_id":"43"},{"_id":"157"}],"year":"2026","title":"Numerical Analysis of the Influence of a Movable Die on Joint Formation in Versatile Self-Piercing Riveting","publication_identifier":{"issn":["1662-9752"]},"author":[{"id":"44935","full_name":"Kaimann, Pia Katharina","last_name":"Kaimann","first_name":"Pia Katharina"},{"last_name":"Bobbert","first_name":"Mathias","full_name":"Bobbert, Mathias","id":"7850"},{"id":"32056","full_name":"Meschut, Gerson","orcid":"0000-0002-2763-1246","first_name":"Gerson","last_name":"Meschut"}],"date_updated":"2026-06-15T15:22:59Z","publication_status":"published","intvolume":"      1185","language":[{"iso":"eng"}],"doi":"10.4028/p-8jkha8"},{"quality_controlled":"1","citation":{"chicago":"Koch, Steffen, Joshua Weber, Gerson Meschut, Claudia Stadelmann, Wolfgang Böhm, and Marion Merklein. “Particle-Reinforced Aluminium Solid Self-Piercing Rivets for Joining Aluminium Alloy Sheets.” In <i>Proceedings in Engineering Mechanics</i>.

How-ever, the reliable and cost-efficient joining of aluminium components remains a challenge. Mechanical joining methods, such as riveting, are frequently used in the automotive and aerospace construction industries. Rivets are made from heat-treated steels. Compared to steel, the use of aluminium materials for fasten-ers offers several advantages in terms of joining properties, particularly in terms of recyclability, corrosion resistance and reduced weight of the joined structure. Additionally, the manufacturing process is shorter since aluminium fasteners do not require coating. However, aluminium rivets can often not be used due to the insufficient mechanical strength of the fastener material in relation to the joining component materials.\r\nThis study systematically investigates the requirements for using solid alu-minium self-piercing rivets. The influence of rivet geometry adjustments on the joint quality is analysed using numerical simulation. The results are used to derive and evaluate an optimised rivet geometry for joining pure aluminium sheets. On this basis, solid self-drilling rivets with optimised geometry are manufactured from particle-reinforced aluminium produced in a continuous extrusion process by machining. The integration of particles increases the material’s strength. Exper-imental tests are conducted to evaluate the use of optimised solid self-piercing rivets. The quality-relevant parameters are determined and evaluated based on macrographs of the joints.","lang":"eng"}],"publication":"Proceedings in Engineering Mechanics","keyword":["Solid self-piercing riveting cdot particle-reinforced aluminium cdot continuous powder extrusion cdot Joining technology cdot Rivet geometry cdot lightweight design"],"type":"book_chapter","department":[{"_id":"43"},{"_id":"157"}],"date_created":"2026-05-26T12:16:57Z","publication_status":"published","date_updated":"2026-06-16T13:21:39Z","year":"2026","title":"Particle-Reinforced Aluminium Solid Self-piercing Rivets for Joining Aluminium Alloy Sheets","publication_identifier":{"isbn":["9783032236401","9783032236418"],"issn":["2731-0221","2731-023X"]},"author":[{"last_name":"Koch","first_name":"Steffen","full_name":"Koch, Steffen"},{"full_name":"Weber, Joshua","first_name":"Joshua","last_name":"Weber"},{"full_name":"Meschut, Gerson","last_name":"Meschut","first_name":"Gerson"},{"full_name":"Stadelmann, Claudia","first_name":"Claudia","last_name":"Stadelmann"},{"last_name":"Böhm","first_name":"Wolfgang","full_name":"Böhm, Wolfgang"},{"last_name":"Merklein","first_name":"Marion","full_name":"Merklein, Marion"}],"doi":"10.1007/978-3-032-23641-8_1","language":[{"iso":"eng"}]}]
