Unravelling repurposing

The Dutch government and leading academics in the field of circular economy propose that “repurposing”, i.e., finding new usages for discarded material, is important to reduce resource usage. Waste collectors, municipalities and start-ups increasingly find ways to develop circular business models, aiming for minimum loss of material integrity. Repurpose is a circular business model strategy which entails using a discarded product or its parts in a new product with a different function.The aim of this research is to gain a better understanding of this promising but academically underexposed circular strategy by empirically exploring its key characteristics and developing a taxonomy that reflects the scope and potential of the concept. The taxonomy development was based on clustering and comparing 96 case examples using key characteristics and critical factors empirically collected by means of 11 semi-structured expert interviews. The taxonomy was iteratively refined and validated by means of workshops with experts.This paper proposes a taxonomy and a comprehensive definition for repurposing. The Repurpose taxonomy distinguishes three main categories with increasing levels of material integrity: “Reprocess”, “Reshape” and “Recontextualize”. The taxonomy provides a refinement of existing circular business model patterns and frameworks for closing material loops strategies. It shows how repurposing may exploit the creative potential of design to fill the gap between reuse and recycling by retaining previously added value with three levels of physical adjustment.

The AVAC-COM communication model and taxonomy: results from application to aviation safety events

Communication problems are acknowledged as hazardous eventualities affecting operations negatively. However, a few systematic attempts have been made to understand the pattern of communication issues and their contribution to safety events. In this paper, we present the AVAC-COM communication model and taxonomy based on the cybernetics approach and a literature review. The model elements and taxonomy variables regard the actors, signals, coders, interference, direction and timing, predictability, decoders, and channels. To test the applicability and potential value of the AVAC-COM framework, we analysed 103 safety investigation reports from aviation published between 1997 and 2016 by the respective authorities of Canada, the United States, Australia, the United Kingdom and the Netherlands. The overall results of the 256 cases of communication flaws detected in the reports suggested that these regarded more frequently Human-Media and Human-Human interactions, verbal and local communications as well as unfamiliarity of the receivers with the messages transmitted. Further statistical tests revealed associations of the region, time period, event severity and operations type with various variables of the AVAC-COM taxonomy. Although the findings are only indicative, they showed the potential of the AVAC-COM model and taxonomy to be used to identify strong and weak communication elements and relationships in documented data such as investigation and hazard reports.

Looking for metacognition: a knowledge taxonomy for psychotherapeutic games

Most of scientific literature on computer games aimed at offering or aiding in psychotherapy has little information on how the game exactly relates to the relatively recent development of the ‘third wave’ of behavioural psychotherapy, which includes metacognition. This paper first introduces metacognition and subsequently studies five cases of psychotherapeutic games (Personal Investigator, Treasure Hunt, Ricky and the Spider, Moodbot and SuperBetter) by looking at them through the lens of Blooms’ Revised Taxonomy of Knowledge. The paper offers design recommendations for future (metacognitive) psychotherapeutic games.

Who says that the Netherlands are subsiding?

This paper is concerned with the governance of geodetic deformation measurements. If we want to know if and how fast a country, or parts of it, are subsiding or rising, who decides that it should be measured and how is the methodology determined? What interests are at stake? How is the proper use and innovation of geodetic methods guaranteed? To be able to answer such and similar questions, a prelude to a taxonomy of governance arrangements for geodetic deformation measurements is presented. Relevant aspects of activities to measure deformations are incorporated into a system to describe governance arrangements. By interviewing nine experts in the field of geodetic deformation measurements in the Netherlands, the activities of companies, institutions and other structures that are concerned with geodetic deformation measurements were analysed, which provided the information to build a system that provides the basis for a taxonomy, which needs further validation in future research.
