    Driven by economic advantages and the idea of disintermediation of business processes, the decentralization of technical and economic systems has become a highly discussed topic in recent years. Extant research primarily investigated the technical implementations of decentralized information systems (IS) and their use by firms in business networks. It became clear that interorganizational relationships and business functions must be transformed to enable the use of decentralized IS (e.g., those related to how firms can be involved in the design, instantiation, operation, and governance of decentralized IS). However, the impact of transforming business functions of individual firms remains largely unclear, obfuscating a comprehensive understanding of the implication of decentralized IS use on internal organizational structures of firms. In this work, we focus on the identification of challenges for firms in using distributed ledger technology (DLT as a representative for decentralized IS) and their effects on the business functions of firms.

    Business ecosystems are dynamic network structures of autonomous actors who contribute individual resources and capabilities towards a shared purpose. This study proposes a design theory to develop a model that describes the fundamental value creation activities in business ecosystems. This research endeavor is embedded in a consortium research project following design science and builds on both the current body of academic knowledge and the experience of. The paper makes three main contributions. Firstly, the study defines a specific problem space, identifies justificatory knowledge, and develops design requirements and principles as the theory’s core. Secondly, a reference model is developed that describes value creation, providing a conceptual grid for further theoretical analysis. Thirdly, the model provides an analytical framework for practitioners, who need to understand which activities should be performed and how these activates should be configured to generate advantages relative to others.

    By enabling a new way to digitize transactions, distributed ledger technology allows to fundamentally change how value is digitally issued, transferred, and stored. Accordingly, «tokenization» refers to the concept of creating a singular identifier on a distributed ledger in terms of a token that may represent anything from financial assets, goods, to other valuable resources. Where tokenization may disrupt our economic system leading to more efficiency or democracy, it is required to gain insights and facilitate the development of use cases associated with this concept. To illustrate how firms can apply tokenization to innovate their businesses, we propose a framework of different token properties, drivers, and barriers for adoption based on literature and expert interviews and present eight archetypical cases derived from an analysis of 129 ventures. This work provides strategic guidance in a token economy and a starting point for future research of viable applications.

    Business Ecosystems are dynamic structures of interdependent actors who co-create value. Despite high interest, the networks remain poorly understood. Participants form partnerships to collaborate with each other, however, these partnerships are fragile. As a possible analytical lens for the success or failure of these partnerships, this study draws on cultural values. By combining value creation characteristics of business ecosystems with the available knowledge base of cultural values, the study develops an artifact which identifies ten crucial cultural values in business ecosystems. The construct functions as a compass of cultural values and helps organizations to anticipate potential issues and recalibrate accordingly. The artifact was developed in a consortium project following the design science research. The paper contributes to a better understanding of value creation and organizational culture in business ecosystems.

    Wearables are used to help motivate individuals to trade their unhealthful behaviors for beneficial ones, thereby preventing the diseases of affluence, which are caused by a sedentary lifestyle. However, inconclusive study results regarding the effectiveness of wearables raise questions about the outcomes of using wearables. Research on the topic paints an ambiguous picture regarding the support wearables offer users in performing beneficial health-related behaviors, leaving the underlying mechanisms of wearable use and its outcomes unexplained. We seek to fill this gap in the literature by means of a critical realist study based on thirty narrative interviews with long-term users of wearables. By identifying seven generative mechanisms that drive users’ interactions with wearables and the subsequent cognitive and behavioral outcomes of that use, we answer the research question concerning how and why users’ interactions with wearables can facilitate positive behavioral and cognitive outcomes. The study makes several contributions to theory and practice.

    Physical inactivity is a global public health problem that poses health risks to individuals and imposes financial burdens on already strained healthcare systems. Wearables that promote regular physical activity and a healthy diet bear great potential to meet these challenges and are increasingly integrated into the healthcare system. However, extant research shows ambivalent results regarding the effectiveness of wearables in improving users’ health behavior. Specifically important is understanding users’ systematic behavior change through wearables. Constructive digitalization of the healthcare system requires a deeper understanding of why some users change their behavior and others do not. Based on self-leadership theory and our analysis of narrative interviews with 50 long-term wearable users, we identify four wearable use patterns that bring about different behav- ioral outcomes: following, ignoring, combining, and self-leading. Our study contributes to self-leadership theory and research on individual health information systems and has practical implications for wearable and healthcare providers.

    Wearables provide great opportunities for improving personal health, but research challenges their capacity to evoke behavioral change effectively. Realizing the full potential of wearables requires a better understanding of users’ behavior change processes. Based on self-efficacy theory, we investigate how wearables influence users’ perceptions of their self-efficacy and subsequent health behavior. Using narrative interviews with twenty-five long-term wearable users, we show that wearables can have both positive and negative effects on users’ perceptions of their self-efficacy and that these perceptions are subject to internal and external contexts, which can positively or negatively affect users’ compliance. We also find that the internal context may have a compounding or neutralizing effect on self-efficacy, despite an adverse external context. Our study shows the contextual and transient nature of self-efficacy, thus contributing to self-efficacy theory and research on wearables and offering practical design implications.

    Business ecosystems are dynamic structures of various actors who co-create value. By combining complementary and substitute services, these actors create integrated offerings. This paper proposes a conceptual model which supports the analysis of ecosystems by de- composing the offering into distinct modules. Each mod- ule represents a beneficiary-provider duality with a specific value proposition and activities to be performed. It further describes, how different service modules con- tribute and may change the network-level purpose. The research follows design science and was facilitated in a consortium setup to integrate practitioners’ insights. The paper contributes by developing design principles for a service configuration model, identifying relevant activities to describe service creation, providing a logic to configure distinct services into a whole, and introducing the concept of substitutes into the discussion.

    The use of persuasive technologies to improve users’ personal health outcomes are becoming increasingly pervasive in the health context. While early research on persuasive technologies highlighted the technology’s individual and societal potential, recent empirical evidence has hinted about the adverse effects of their use. However, little is known about the causes of, experiences with, and coping reactions to these adverse effects. To fill this gap, we conduct an exploratory study of wearable technologies’ adverse effects on users based on twenty-five narrative interviews. Employing a technostress lens, we find two distinct patterns–control stress and validation stress–that show that users experience these adverse effects by revolving through a circular process of technostress and relying on various mechanisms to cope with it. We describe contributions to the literature and implications for research and practice.

    Wearables gelten als Hoffnungsträger der heutigen Zeit: Sie sollen die individuelle Gesundheit von Nutzern verbessern, dadurch die Gesundheitskosten senken und die gesellschaftliche Wohlfahrt erhöhen. Doch wie steht es wirklich um die Potenziale von Wearables? Dieser Beitrag gibt Einblick in Nutzung und Auswirkungen von Wearables und zeigt Implikationen für den Einsatz im betrieblichen Gesundheitsmanagement auf.
