This paper addresses the design dilemmas that arise when distributed ledger technologies (DLT) are to be applied in the governance of artificial material commons. DLTs, such as blockchain, are often presented as enabling technologies for self-governing communities, provided by their consensus mechanisms, …

Designing wearable technology to make physical activity an integral and routine part of people’s everyday life is a challenge, requiring expertise from different disciplines. COMMONS, a research prototype, is a serious game designed to facilitate interdisciplinary collaboration early in the design process. …

In this article, we trace open design back to its roots and – by building on experiences from a recent open design initiative as well as research into open design practices – we relate the 'how to organize' question of open design to earlier theories of common, shared resources.

The urgency for developing a circular economy is growing, and more and more companies and organisations are concerned with the importance of adapting their business to fit a changing economy. However, many analyses on the circular economy are still rather abstract and there is a lack of understanding …

Visual Thinking (VT) is concerned with the use of visual resources (diagrams, simple drawings, short texts) to represent, organize or communicate ideas or contents. VT aims to favor the understanding of concepts to `translate' to a visual representation a content or process. Lower thinking skills to …

When engaging in social interaction, people rely on their ability to reason about unobservable mental content of others, which includes goals, intentions, and beliefs. This so-called theory of mind ability allows them to more easily understand, predict, and influence the behavior of others. People even …

For successful project management, it is essential to adopt a suitable project management approach. This approach must be based on a thorough understanding of the project characteristics in its context. In this paper we present a diagnostic model that aims to advance this understanding. We distinguish …

Abstraction is considered an essential aspect of computational thinking. Primary schools are starting to include computational thinking into the curriculum. However, in order to guide their support, teachers need to know how to recognize abstraction. In this paper, we present how we can observe abstraction …

The purpose of this study was to determine the efficacy of an online self-tracking program on physical activity, glycated hemoglobin, and other health measures in patients with type 2 diabetes. Seventy-two patients with type 2 diabetes were randomly assigned to an intervention or control group. All participants …

We report on a first field test in which miniaturized sensor motes were used to explore and inspect an operational pipeline by performing in situ measurements. The spherical sensor motes with a diameter of 39 mm were equipped with an inertial measurement unit (IMU) measuring 3-D acceleration, rotation, …
