Abstract: Besides increasing transparency and demonstrating awareness of the author, self-reported limitations enable other researchers to effectively learn from, build on, validate, and extend the original work. However, this topic is understudied in information systems design science research (IS DSR). The study has assessed 243 IS DSR papers published in the period 2013–2022 and built a typology of the 19 most relevant limitations, organized into four categories: (1) Input Knowledge and Technology, (2) Research Process, (3) Resulting Artifact, and (4) Design Knowledge. Further, the contribution suggests actions to mitigate each type of limitation throughout the entire IS DSR project lifecycle. The authors have also created guidelines to report the limitations in a useful way for knowledge accumulation. The proposed typology and guidelines enable reviewers and editors to better frame self-reported limitations, assess rigor and relevance more systematically, and provide more precise feedback. Moreover, the contribution may help design researchers identify, mitigate, and effectively communicate the uncertainties inherent to all scientific advances. Collapse

Abstract: The role played by decentralised services in the obfuscation of crypto-asset transactions performed on transparent blockchains has increasingly captured the attention of regulators. This is exemplified by the headlines about the U.S. Treasury's sanctions on the Ethereum-based mixer Tornado Cash. Yet, despite the existing controversies on the use of mixers, the different functionalities of these information systems with an inherent dark side remain to be explored by the literature. So far, contributions primarily encompass technical works and studies that focus on the Bitcoin ecosystem. This paper puts forward a multi-layer taxonomy of the smart-contract-based -and, therefore, functionally richer -family of mixers on Ethereum. Our proposed taxonomy is grounded on (1) a review of existing literature, (2) an analysis of mixers' project documentation, (3) their corresponding smart contracts, and (4) expert interviews. Our evaluation included the application of the taxonomy to two mixers -RAILGUN and zkBob. The taxonomy represents a valuable tool for law enforcement, regulators, and other stakeholders to explore critical properties affecting compliance and use of Ethereum-based mixers. Collapse

Abstract: Should hospitals source electronic health records (EHR) systems from a single vendor or multiple vendors to deliver high-value care? We study hospitals’ EHR sourcing strategies based on their degree of integration with physician practices and its impact on the value of healthcare delivered. We propose a novel framework to define healthcare value as the extent to which a hospital effectively expends clinical resources to deliver services that improve patient outcomes. Drawing on modular systems and transaction cost economics theories, we propose a moderated-mediation model that explores the pathways through which EHR sourcing strategies can create value in healthcare. We test our research hypotheses on a large, longitudinal sample of U.S. hospitals and observe that hospitals with EHR configurations closer to single sourcing strategies exhibit greater health information sharing compared with hospitals with multisourced EHR systems. Furthermore, we find that hospital-physician practice integration moderates the impact of single sourcing on health information sharing, which in turn, improves value. Specifically, tighter integration between hospitals and physician practices can create greater value if it is aligned with hospitals’ EHR sourcing strategies. As the healthcare industry moves toward value-based payment reform, our findings provide a useful roadmap to practitioners and policy makers to improve the performance of hospitals and healthcare providers.

Abstract: This work proposes a holistic decision support tool to be used by diverse stakeholders and decision-makers, integrating experimental data. Considering the characteristics of each region, the tool aids in defining the most suitable testing strategies per country or region: number of tests, time, cost, type of pool strategy based on prevalence rate interval, and the use of centralization vs. decentralization of testing strategies. The tool con­ tributes to the field of decision support systems theoretically by introducing a novel model for testing decisions in extreme situations within a specific region, and practically, by demonstrating how laboratory data can be applied to real-life decision-making in that same region. This tool has been validated with two real case studies (Portugal and France) and has applied, as input data, real experimental results. The results suggested tree- and matrixbased strategies for low and high prevalence rates. A decentralized testing strategy improves the financial and time gains introduced by pool testing; however, centralizing the decisions shows a more straightforward implementation and resource management of the pool testing system with a low-performance loss. Therefore, there might be a solution to consider overcoming operational restrictions. Collapse

Abstract: Advances in digital platforms allow influencers to use live shows to showcase products, which has given rise to live-stream shopping. Moreover, new communication forms have emerged, such as the metaverse. The social interactions that occur in these immersive environments foster influencer-follower interactions. This research compares the impact of live-stream shopping on followers’ experiences and behaviors on two communication channels (live shows on Instagram and in the metaverse) and analyses the moderating role of content involvement in telepresence. Data were collected in a between-subjects quasi-field experiment. Two scenarios that differed in degree of telepresence were created, a live show on Instagram and a live show in the metaverse. The results showed that telepresence is an important part of the user experience and in the success of live shows. Telepresence was seen to have a major influence on experiential value, but not on instrumental value. Both values provided followers with satisfaction with the experience. This satisfaction generated stickiness intention and intention to recommend the influencers’ live shows. The effect of telepresence on experiential value was greater for followers less involved with the influencer’s content. This research is pioneering in comparing an established platform, Instagram, with the metaverse. Despite the greater experiential value provided by the metaverse, to increase its instrumental value metaverse spaces needs to be further developed. Collapse

Abstract: While the positive aspects of the flow state have been widely researched, the effects of being aware of this state and the negative consequences still need to be explored. The loss of awareness that flow state may bring can lead to the purchase of products that consumers afterward regret and want to return them. This research aims to understand flow consciousness’s effect on consumer post-purchase regret from a dual perspective (process and outcome regret). The relevance of these relationships is also examined by analyzing the differences between 2 groups: maximizers and satisficers consumers. Through a structural equation model based on covariances tested with EQS 6.4, the results show that flow consciousness generates process regret but not outcome regret. How­ ever, the differences found between the two groups are worth noting. The research sheds light on the effect of flow consciousness on regret and provides insight into the mechanism of product return through post-purchase regret. The theoretical and managerial implications for e-commerce retailers are discussed. Collapse

Abstract: Workarounds are goal-driven deviations from the standard operating procedures performed to overcome obstacles constraining day-to-day work. Despite starting as temporary fixes, they can become established across an organisation and trigger the innovation of processes and IT artefacts that can resolve misfits permanently. Although prior research has elicited antecedents and types of workarounds, it is not known how workarounds diffuse in an organisation and, thereby, innovating co-workers' activities, IT artefacts, and organisational structures. The results of our multiple two-year case study provide unique empirical insights into the diffusion of workarounds and how they can act as generative mechanisms for bottom-up process innovation.

Abstract: Introduction to the special issueInformation Communication Technology (ICT): People, Culture, and Globalization The broad objective of this Special Issue (SI) was to deliver new insights into the management of Information Communication Technology (ICT) in the view of ICT users', consumers', or managers' cultural diversity, in order to enhance our understanding of how ICT connects people across countries or cultures and affects their behavior. Understanding how ICT and culture affect human decisions is timely and of crucial importance because ICT is a driving force behind almost any form of business internationalization or globalization. Although the COVID-19 pandemic and Russia's war in Ukraine currently lead to a slowdown in business globalization, it is clear that many firms continue to operate in, or expand into foreign countries, as well as deal with people from different cultures within a country. Almost all firms and organizations today use ICT to connect with people and must therefore address questions of how culture affects ICT usage and user behavior, and what the consequences are for the organization.We therefore aimed to bring together a group of international researchers in marketing and related disciplines broadly concerned with business globalization and ICT management. The SI was initially planned as part of the Royal Bank International Research Seminar (RBIRS), which has since 2001 been very successfully held bi-annually in Montreal, Canada. RBIRC, the international conference version, was also very successfully held in 2010 in Tokyo, Japan, in 2012 in Shanghai, China, and in 2016 in Wuxi, China. RBRIS has since many years brought together likeminded researchers from across the globe, who share research interest frequently in fields related to the role of culture in consumer behavior, how consumers interact with technology, as well as links between the two. We thus planned to organize the 2020 edition of RBIRC at Kedge Business School in Marseille, France and link this SI to it as an opportunity for researchers to publish innovative and relevant work. Unfortunately, the emergence of COVID-19 as a global pandemic has scuttled our ambitious plans, and we were ultimately forced to cancel RBIRC 2020 for the well-known restrictions that prevented us making the conference meeting happen in Marseille. We regret these circumstances very much and hope that future issues of RBIRS can happen in-person again.Given that a number of authors had prepared targeted manuscripts before we cancelled the conference, we decided to maintain the SI, with the kind approval of the Editor-in-Chief, Yogesh Dwivedi, to whom we are most grateful. Despite the difficult circumstances, we received 11 manuscripts that underwent careful peer reviews, and we have finally accepted three of them for inclusion into the SI. The three papers cover three different forms of modern ICT, namely social media, human-like service robots, and P2P accommodation-sharing platforms. The authors of these papers use various types of methods and data to tackle different phenomena that enhance our understanding of how culture affects ICT usage and behavior.The first paper by Takhar, Bebek, & Jamal (2021) offers insights into the role of social media's liminal characteristics (anonymity and freedom) for ethnic minority consumers' social-cultural identity construction. Given their multicultural social environments, ethnic consumers in particular experience cultural tensions in their daily lives related to potentially conflicting online-and offline cultural-social identities. Focusing on Instagram and third-generation British Sikhs, and using a multi-method qualitative research design (observations, nethnography, and semi-structured interviews), the authors demonstrate how liminality enables imagined or idealized social-cultural identities with important implications for social media marketing, such as virtual brand communities. Marketers should consider liminality as a factor that empowers consumers' identity construction, which can help them develop stronger and more sustainable customer relationships.The second paper in this SI, written by Pitardi, Bartikowski, Osburg, Collapse

Abstract: Accountability is crucial to make stakeholders of Artificial Intelligence (AI)-based systems justify their actions, thereby explaining the harm such systems cause to AI users. Due to the importance of accountability in the context of AI, accountability was introduced into IS research through literature reviews. Therefore, while IS research's understanding of accountability covers the necessary depth, it comes at the expense of its essential breadth. Using a bibliometric analysis with 19,978 English-language papers, we shed light on the essential breadth posing three W-and one H-questions (When, What, Whereof, and How). Therefore, we contribute to IS research by highlighting the urgent need to revise existing definitions of accountability in the context of AI and establish them in IS research. We argue that a missing revision leads to non-transferrable findings within IS research. Accordingly, this study serves as a starting point for adapting definitions and creating a shared understanding in IS research. Collapse

How AI Developers’ Perceived Accountability Shapes Their AI Design Decisions

Abstract: While designing artificial intelligence (AI)-based systems, AI developers usually have to justify their design decisions and, thus, are accountable for their actions and how they design AI-based systems. Crucial facets of AI (i.e., autonomy, inscrutability, and learning) notably cause potential accountability issues that AI developers must consider in their design decisions, which has received little attention in prior literature. Drawing on self-determination theory and accountability literature, we conducted a scenariobased survey (n=132). We show that AI developers who perceive themselves as accountable tend to design AI-based systems to be less autonomous and inscrutable but more capable of learning when deployed. Our mediation analyses suggest that perceived job autonomy can partially explain these direct effects. Therefore, AI design decisions depend on individual and organizational settings and must be considered from different perspectives. Thus, we contribute to a better understanding of the effects of AI developers' perceived accountability when designing AI-based systems. Collapse
