After being granted asylum in European countries, refugees need to go through a multitude of administrative processes before they can participate in society. However, these processes are often challenging, as refugees struggle to understand them, lack instructions for managing paperwork, and do not possess the required language skills. Prior research emphasizes the role of information and communication technologies to simplify and enable refugee-friendly administrative processes. However, recent research and existing applications mainly focus on information retrieval and do not offer assistance for understanding official letters, completing administrative forms, and managing corresponding documents. Furthermore, refugees are often reluctant to use existing applications as they do not trust their host country’s governments and public authorities. In this research, we aim to address this functional and trust gap. We follow a design science research approach to develop a design for a refugee-centric and trustworthy mobile application that assists refugees along administrative processes. In doing so, we identify three design principles that may guide the development of such applications for refugees. [less ▲]

Fragmentation and limited accessibility of charging infrastructure impede the adoption of electric vehicles. To improve the availability of charging infrastructure independent of providers, eRoaming offers a promising solution. Yet, current eRoaming systems are typically centralized, which raises concerns of market power concentration. While the use of blockchain technology can obviate such concerns, it comes with significant privacy challenges. To address these challenges, we explore a combination of blockchain with self-sovereign identity. Specifically, we apply a design science research approach, which helps us to identify requirements, derive a conceptual architecture, and deduce design principles for decentralized eRoaming and beyond. We find that blockchain may best leverage its benefits when it takes a backseat as a public registry for legal entities. Moreover, we find that the use of self-sovereign identities could improve compliance with privacy regulations, but they should not be overused. [less ▲]

Blockchains enable distributed operation, decentralized control, and token-based representations of tangible and intangible assets. Organizations commonly use blockchain technology to foster collaboration. In this paper, we investigate the use of blockchain to foster competition. We conduct a single-case study of Germany’s mobility-as-a-service community and its efforts to use blockchain as a technical backbone for mobility ecosystems. The community views blockchain as a technology that embodies organizing principles of empowerment and equality. These principles motivated the community to rethink ecosystem structure. In particular, the community began to question the exclusive, non-adversarial position of mobility service aggregators. We find that rethinking this position might shift their competitive focus from the inter- to the intra-ecosystem level and enables the creation of a larger ecosystem. As a second-order effect, the community began to rethink ecosystem governance. Specifically, it began to explore options for effectively distributed decision making while safeguarding efficiency.
