  abstract     = {{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.}},

  abstract     = {{This paper presents a holistic framework for the transition from diesel to electric bus networks, crucial for meeting EU regulations targeting 100% zero-emission urban buses by 2035. 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.}},

                  <jats:p>Creativity and innovation are often understood as the result of a complex interplay of hierarchical factors, such as national, regional and firm characteristics, or between organisational and individual factors. While recent applications of qualitative comparative analysis (QCA) have begun to model such configurational links, their hierarchical nature has received little empirical attention. As this paper demonstrates, theories that posit hierarchical configurations can and should be explored using the two‐step variant of QCA. The paper outlines the potential of the method for the field of creativity and innovation and helps to navigate key modelling decisions. An illustrative study explores the occurrence of informal employee innovation behaviour—workarounds—based on the Ability‐Motivation‐Opportunity (AMO) framework. The results of the two‐step QCA are superior in terms of reduced limited diversity and complexity to those of the conventional one‐step QCA. Overall, the method has considerable potential for empirically capturing the complex, hierarchical interactions inherent in many innovation processes.</jats:p>}},

  abstract     = {{Purpose: The purpose of this study is to identify, analyze, and explain the implications that could
arise for service settings if AI systems develop, or are perceived to develop, consciousness – the
ability to acknowledge their own existence and the capacity for positive or negative experiences.

Design/methodology/approach: This study proposes and explores four hypothetical scenarios in
which conscious AI in service could manifest. We contextualize our resulting typology in the
health service context and integrate extant literature on technology-enabled service, AI
consciousness, and AI ethics into the narrative.

Findings: This study provides a unique theoretical contribution to service research in the form of
a Type IV theory. It enables future service researchers to apprehend, explain, and predict how
functionally conscious AI in service might unfold.

Originality: An increasingly prolific public discourse acknowledges that conscious AI systems
may emerge. Against this backdrop, this study aims to systematically explore a question that is
perhaps the most critical and timely, but also inherently speculative, in relation to AI in service
research by introducing much-needed theory and terminology.

Practical implications: The ethical use of conscious AI in service could emerge as a distinct
competitive advantage in the future. Achieving this outcome involves speculative yet actionable
recommendations that include training, guiding, and controlling how humans engage with such
systems, developing appropriate wellbeing protocols for functionally conscious AI systems, and
establishing AI rights and governance frameworks.}},

Employing the Lerner Index as a non-structural measure of market power, our findings suggest that the impact of banking market power on ESG scores varies by region and the respective loan or deposit market. We find a negative effect of loan and deposit market power on ESG scores of European banks whereas the opposite effect can be observed for North American banks exhibiting loan market power. Further sensitivity analyses reveal that factors such as banks being Global Systemically Important (G-SIBs), and different ESG-related events like the Paris Agreement, the reemergence of the #MeToo movement and the COVID-19 pandemic may also explain the relationship between bank market power and ESG scores. Overall, our results underline that banking market power plays a pivotal role in enforcing ESG commitments in banking, offering key insights for policymakers, regulators, and banking stakeholders.}},

Darin liegt gleichzeitig die Chance des ICM, da sich Potenziale und Herausforderungen zeigen, die den Reflexionsprozess fördern können. Vor diesem Hintergrund untersucht der Beitrag, wie das ICM die Entwicklung intrapersonaler Kompetenzen unterstützen kann. Zentrale intrapersonalen Kompetenzen sind Emotionsregulation, Resilienz, Selbstwirksamkeit und Reflexivität. Während Lehrende in der Pre-Class-Phase des ICM potenzielle Belastungen antizipieren können, findet in der In-Class-Phase eine Echtzeit-Reflexion im Unterrichtshandeln statt. Erkenntnisse aus der Post-Class-Phase werden in die zukünftige Lehrplanung überführt. Die vorgeschlagene Reflexionsarchitektur verknüpft Wahrnehmen, Deuten, Regulieren, Transferieren mit den ICM-Phasen. Der “Rucksack” dient dabei als Strukturhilfe für die Reflexion des eigenen „professionellen Gepäcks“. Für die Praxis wird eine Kombination aus Fallanalysen, Leitfragen und kollegialem Austausch vorgeschlagen.}},

  abstract     = {{<jats:p>We return to the theoretical foundations of absorptive capacity and test the idea that personal experience in a field makes it easier for a firm’s inventors to recognize and build upon knowledge in that field from other local firms. We propose a new empirical model of localized knowledge diffusion, which (1) measures a firm’s absorptive capacity by its inventors’ prior experience in a field, (2) uses a death instrument to exogenously vary the availability of knowledge of the same collaborative patent in different regions, and (3) estimates the difference in citation likelihood from all subsequent inventors across both regions as a function of a potentially citing inventor’s prior experience in the field. Consistent with the original theory of absorptive capacity, firms whose inventors have prior experience in a field are more likely to use locally available interpersonal knowledge from other firms; furthermore, this effect declines monotonically with distance. Although the effects strengthen for more recent experience and multidisciplinary knowledge, the greatest benefits accrue to firms in the interaction—those whose inventors have more recent experience and that seek to absorb multidisciplinary knowledge. Interpersonal absorptive capacity within firms does not appear to localize.</jats:p>
