This study addresses the formation of “viscous fingering” instabilities in structural adhesive joints, which are induced by thermally driven relative displacements during the liquid phase of the adhesive. Using a component-like specimen “bridge specimen,” the dependency of this phenomenon on process temperature and structural stiffness (rivet distance) was characterized. Experimental results reveal that while the relative displacement scales cubically with the free buckling length, the resulting adhesive area reduction follows an exponential trend, leading to a loss of effective bond area of up to 79%, which significantly compromises the joint strength in automotive applications. To predict these process-induced defects, a thermo-chemo-viscoelastic-viscoplastic adhesive model implemented in LS-DYNA was applied. The model combines curing kinetics, viscoelastic relaxation, and pressure-dependent plasticity and features a geometric damage parameter (D) that captures the adhesive area reduction caused by viscous fingering as an exponential function of the accumulated normal strain in the liquid phase. This damage parameter, calibrated on base-specimen level, was transferred to the component geometry. The simulation demonstrated high predictive accuracy with a maximum deviation of the adhesive area reduction of 3.1% compared to experimental data. This validates the model’s capability to predict manufacturing-induced damage in complex hybrid structures solely based on thermal boundary conditions. article_type: original author: - first_name: Mohamad full_name: Al Trjman, Mohamad id: '65415' last_name: Al Trjman - first_name: Felix full_name: Beule, Felix id: '66192' last_name: Beule - first_name: Dominik full_name: Teutenberg, Dominik id: '537' last_name: Teutenberg - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 - first_name: Julia full_name: Riese, Julia id: '101499' last_name: Riese orcid: 0000-0002-3053-0534 citation: ama: Al Trjman M, Beule F, Teutenberg D, Meschut G, Riese J.

Systems theory offers powerful concepts to address challenges of growing system complexity and non-systemic design approaches in information systems. Despite its systemic origins, systems theory remains a peripheral topic in IS. The study addresses this gap by introducing a comprehensive framework of 52 systems-theoretical concepts to guide the design of complex IS artifacts. We synthesize scattered systems knowledge from diverse disciplines to provide a unified level of abstraction for complex information system design. We apply the framework to a use case of business reputation systems to show how the systems lens informs the design of a novel, complex information system. We make three key contributions to the literature. First, the framework provides a common ground for interdisciplinary research in information system design. Second, it offers a unified level of abstraction grounded in systems theory that serves as a coherent basis for artifact design. Third, it demonstrates the potential of systems theory as a foundational justificatory knowledge base. Furthermore, we provide guidance on applying the framework across multiple modes of reasoning, alongside further application guidelines. The study thus serves as a bridge between the body of systems knowledge and contextual design in IS. alternative_title: - Design Your System article_type: review author: - first_name: Ulvi full_name: Ibrahimli, Ulvi last_name: Ibrahimli - first_name: Simon full_name: Hemmrich, Simon last_name: Hemmrich - first_name: Axel full_name: Winkelmann, Axel last_name: Winkelmann citation: ama: 'Ibrahimli U, Hemmrich S, Winkelmann A.

Cli-ents who have not worked with a particular consultancy face considerable risk when they place an order while lacking reliable information about the service quality they can expect. There is a strong link between trust and reputation, as the positive reputation of a consultancy can act as a substitute for a new client’s missing individual experience with the provider, fostering trust in the service quali-ty. Thus, creating, maintaining, and demonstrating a good reputation is of signifi-cant importance for consultancies in a very competitive industry.\r\nTo facilitate trustworthy signals, we design and implement a novel reputation mechanism that carries a monetary weight stored on a blockchain network as an immutable, decentralized, and transparent ledger. Based on an implementation in the Ethereum network and subsequent evaluation, we conclude that the reputation mechanism can contribute to leveling information asymmetry and reducing risk while increasing reputation and trust. The mechanism lends itself to being used in other business-to-business scenarios that suffer from similar information asymmetries." author: - first_name: Simon full_name: Hemmrich, Simon id: '83557' last_name: Hemmrich - first_name: Volker full_name: Nissen, Volker last_name: Nissen citation: ama: 'Hemmrich S, Nissen V.

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. article_number: '37' article_type: original author: - first_name: Daniel full_name: Beverungen, Daniel last_name: Beverungen - first_name: Jens full_name: Poeppelbuss, Jens last_name: Poeppelbuss - first_name: Simon full_name: Hemmrich, Simon last_name: Hemmrich - first_name: Taskeen full_name: Iqbal, Taskeen last_name: Iqbal citation: ama: Beverungen D, Poeppelbuss J, Hemmrich S, Iqbal T.

Their query rewriting algorithms focus on languages like conjunctive queries and their unions, which were developed for relational data and are poorly suited for graph data. Moreover, they also limit the expressiveness of the ontology languages that admit rewritings, restricting them to those that enjoy the so-called FO-rewritability property. Rewritings have thus focused on the DL-Lite family of Description Logics. In this paper, we propose a technique for rewriting a family of navigational queries for a suitably tailored fragment of ELHI. Leveraging navigational features in the target query language, we can include some widely-used axiom shapes not supported by DL-Lite. We implemented a proof-of-concept prototype that rewrites into Cypher queries, and tested it on a real-world cognitive neuroscience use case with promising results. author: - first_name: Bianca full_name: Löhnert, Bianca last_name: Löhnert - first_name: Nikolaus full_name: Augsten, Nikolaus last_name: Augsten - first_name: Cem full_name: Okulmus, Cem id: '114410' last_name: Okulmus orcid: 0000-0002-7742-0439 - first_name: Magdalena full_name: Ortiz, Magdalena last_name: Ortiz citation: ama: 'Löhnert B, Augsten N, Okulmus C, Ortiz M.

These can include operating vehicles that differ regarding their characteristics and application profile from privately owned cars in motorized individual transport. Studies on life cycle assessment and life cycle engineering of vehicle lightweight structures are mainly limited to these privately owned cars and the impact category of climate change. In this paper, a method for life cycle assessment-based engineering of lightweight structures in vehicles for various mobility system applications, including on-demand mobility services, is developed. The method enables the holistic life cycle assessment of lightweight structures in different mobility system applications considering parameter changes at the upstream products, component, subsystem, vehicle and mobility system levels, as well as the integration of results into engineering activities. A case study is used to show that the vehicle and mobility system application of lightweight structures can significantly influence their environmental impacts and the selection of ecologically preferable product designs. The application in vehicles for on-demand mobility services can lead to an increase in absolute use stage energy demand and environmental impacts compared to applications in privately owned vehicles for motorized individual transport. However, normalized to the transport performance provided, the lifecycle environmental impacts of structural components in vehicles for on-demand mobility services can be lower than in vehicles for motorized individual transport. The paper contributes methodically and with quantitative results to improved decision making in life cycle engineering activities for lightweight structures in mobility system applications. article_number: '101058' article_type: original author: - first_name: Moritz full_name: Ostermann, Moritz id: '44763' last_name: Ostermann orcid: https://orcid.org/0000-0003-1146-0443 - first_name: Eric full_name: Dierkes, Eric last_name: Dierkes - first_name: Thorsten full_name: Marten, Thorsten id: '338' last_name: Marten orcid: 0009-0001-6433-7839 - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster citation: ama: Ostermann M, Dierkes E, Marten T, Tröster T.

However, the role of V&V engineers is often not given sufficient attention. Based on a systematic literature analysis and practical observations, a four-step method for Test-oriented Resilient Requirements Engineering (ToRRE) is developed. The steps are planning V&V, executing V&V activities, documenting V&V activities and analyzing results of V&V activities. Applying ToRRE ensures continuous information flow and traceability. Engineers are enabled to analyze requirements using engineering artifacts connected through Model-Based Systems Engineering. Adopting methods for Model-Based Effect Chain analysis to evaluated test cases and test scenarios, conclusions on requirements engineering and change management are enabled. The method is evaluated in an EU research project. author: - first_name: Iris full_name: Gräßler, Iris id: '47565' last_name: Gräßler orcid: 0000-0001-5765-971X - first_name: Marcel full_name: Ebel, Marcel id: '81788' last_name: Ebel orcid: https://orcid.org/0009-0007-5400-4436 citation: ama: 'Gräßler I, Ebel M.

Funding organizations have started to require that research applicants pay attention to inclusion and diversity by considering gender dimensions and other diversity factors in their project plans and ensuring gender equality during execution. Based on an extensive literature research and expert discussions on how to develop and implement diversity strategies in large collaborative research projects, we argue that there is a lack of practical advice in existing literature. Drawing from our own experiences in conceptualizing and implementing a Diversity Program across four universities in Germany, we propose a framework for effectively integrating diversity into collaborative research initiatives across various academic fields. author: - first_name: Mariya full_name: Lorke, Mariya last_name: Lorke - first_name: Rena full_name: Amelung, Rena last_name: Amelung - first_name: Peter full_name: Kuchling, Peter last_name: Kuchling - first_name: Benjamin full_name: Paaßen, Benjamin last_name: Paaßen - first_name: Miriam full_name: Pein-Hackelbusch, Miriam last_name: Pein-Hackelbusch - first_name: Franziska Margarete full_name: Schloots, Franziska Margarete id: '33185' last_name: Schloots orcid: 0009-0008-9673-2615 - first_name: Klara full_name: Schulz, Klara last_name: Schulz - first_name: Annette full_name: Nauerth, Annette last_name: Nauerth citation: ama: 'Lorke M, Amelung R, Kuchling P, 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.

When operated under partially flooded conditions, they provide significant mass transfer improvement compared to common structured packings. In this work, a rate-based model including novel mass transfer correlations is presented and validated using a comprehensive experimental database for the reactive absorption of CO2 into aqueous monoethanolamine. The proposed rate-based approach is capable of accounting for axial dispersion, thereby enabling the evaluation of the effect of liquid-phase backmixing on the mass transfer performance. The validated rate-based model is used to evaluate the separation performance of sandwich packings. Compared with structured packings, up to 10 % higher mass transfer rates are obtained. article_number: '122681' article_type: original author: - first_name: Patrick full_name: Franke, Patrick id: '93922' last_name: Franke - first_name: Markus full_name: Schubert, Markus last_name: Schubert - first_name: Uwe full_name: Hampel, Uwe last_name: Hampel - first_name: Eugeny Y. full_name: Kenig, Eugeny Y. id: '665' last_name: Kenig citation: ama: Franke P, Schubert M, Hampel U, Kenig EY.

They are recommended for long-term use cases like e.g. firmware signing. However, stateful signature schemes require to properly manage a so-called state. In stateful signature schemes like LMS and XMSS, signing keys consist of a set of keys of a one-time signature scheme and it has to be guaranteed that each one-time key is used only once. This is done by updating a state in each signature computation, basically recording which one-time keys have already been used. While this is straightforward in centralized systems, in distributed systems like secure enclaves consisting of e.g. multiple hardware security modules (HSMs) with limited communication keeping a distributed state that at any point in time is consistent among all parties involved presents a challenge. This challenge is not addressed by the current standardization processes. \r\nIn this paper we present a security model for the distributed key management of post-quantum secure stateful signatures like XMSS and LMS. We also present a simple, efficient, and easy to implement protocol proven secure in this security model, i.e. the protocol guarantees at any point in time a consistent state among the parties in a distributed system, like a distributed security enclave. The security model is defined in the universal composabilty (UC) framework by Ran Canetti by providing an ideal functionality for the distributed key management for stateful signatures. Hence our protocol remains secure even if arbitrarily composed with other instances of the same or other protocols, a necessity for the security of distributed key management protocols. Our main application are security enclaves consisting of HSMs, but the model and the protocol can easily be adapted to other scenarios of distributed key management of stateful signature schemes." author: - first_name: Johannes full_name: Blömer, Johannes id: '23' last_name: Blömer - first_name: Henrik full_name: Bröcher, Henrik id: '41047' last_name: Bröcher orcid: 0009-0008-3938-5485 - first_name: Volker full_name: Krummel, Volker last_name: Krummel - first_name: Laurens Alexander full_name: Porzenheim, Laurens Alexander id: '47434' last_name: Porzenheim citation: ama: Blömer J, Bröcher H, Krummel V, Porzenheim LA.

We analyse whether heteroclinic structures can arise in network dynamics with higher-order interactions which describe the nonlinear interactions between three or more units. We find that while commonly analysed model equations such as network dynamics on undirected hypergraphs may be useful to describe local dynamics such as cluster synchronization, they give rise to obstructions that allow to design of heteroclinic structures in phase space. By contrast, directed hypergraphs break the homogeneity and lead to vector fields that support heteroclinic structures. article_type: original author: - first_name: Christian full_name: Bick, Christian last_name: Bick - first_name: Sören full_name: von der Gracht, Sören id: '97359' last_name: von der Gracht orcid: 0000-0002-8054-2058 citation: ama: Bick C, von der Gracht S.

For example, property damage to shared accommodations imposes burdens on both sharing platforms and hosts, especially if misbehaving guests purposefully, not coincidentally conceal, or fail to report damages. Such misbehavior might be facilitated by remote listing management and the lack of face-to-face interactions between hosts and guests. Therefore, this study investigated the effects of host–guest interaction modes (face-to-face, online-only) and frequency on guests’ misbehavior concealment intentions. Social identification and irritation emerged as bright- and dark side mediators, respectively. Guests who interacted face-to-face (vs. online-only) with hosts exhibited weaker intentions to conceal their misbehavior due to increased social identification. Platforms can elicit social identification by engaging guests in virtual communities. However, when face-to-face interactions become excessive, guests experience irritation and are more likely to conceal their misbehavior. These insights offer practical implications for both peer-to-peer sharing platforms and hosts. article_number: '114582' article_type: original author: - first_name: Edna full_name: Ozuna, Edna id: '103813' last_name: Ozuna - first_name: Lena full_name: Steinhoff, Lena id: '4336' last_name: Steinhoff citation: ama: 'Ozuna E, Steinhoff L. “Look me in the eye, customer”: How do face-to-face interactions in peer-to-peer sharing economy services affect customers’ misbehavior concealment intentions?

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.
