When products are no longer suitable for reuse, repair or refurbishment, they are discarded and recycled, often losing a lot of value (downcycling). Repurpose is a strategy that gives discarded products or obsolete parts a new, high-quality purpose, also known as upcycling. With Repurpose, the value added to the material in the shaping production process or during the use phase is not lost, as is the case with Recycling. For example, with Repurpose, the unique shape, color or composition of an object is preserved in a new product. Repurpose is therefore higher on the circularity ladder than Recycling.But how do you do that? Designing and producing from an existing product or part is challenging due to, among other things, variation in quality and limited or temporary availability. But it also offers opportunities because you can use unique properties or the origin of a product.During the DDW the AUAS showcases the results of the research project Repurpose Driven Design & Manufacturing, and informs and inspires the audience to apply Repurpose in their designs.

This paper describes a concept where products are equipped with agents that will assist in recycling and repairing the product. These so-called product agents represent the product in cyberspace and are capable to negotiate with other products in case of recycling or repair. Some product agents of broken products will offer spare parts, other agents will look for spare parts to repair a broken product. On the average this will enlarge the lifetime of a product and in some cases prevent wasting resources. Apart from reuse of spare parts these agents will also help to locate rare elements in a device, so these elements can be recycled more easily.

The principal aim of this study is to explore the relations between work domains and the work-related learning of workers. The article is intended to provide insight into the learning experiences of Dutch police officers during the course of their daily work. Interviews regarding actual learning events and subsequent changes in knowledge, skills or attitudes were conducted with police officers from different parts of the country and in different stages of their careers. Interpretative analyses grounded in the notion of intentionality and developmental relatedness revealed how and in what kinds of work domains police officers appear to learn. HOMALS analysis showed work-related learning activities to vary with different kinds of work domains. The implications for training and development involve the role of colleagues in different hierarchical positions for learning and they also concern the utility of the conceptualisation of work-related learning presented here.

The NDT methods currently used in aviation MRO are predominantly labour-intensive and time-consuming processes performed by human operators throughout the lifespan of an aircraft. These techniques are time-consuming, require perpetual training and are highly dependent on the operator's skills. Thus, there is a growing need for more efficient, automated, and accurate NDT tools that will be able to provide faster and less labour-intensive assessments. This study presents a novel, non-contact, automated NDT scanning system under development, which aims to reduce the inspection time significantly. The proposed technique uses a non-contact, Lamb wave-based approach. A further essential step during the process is to use an automated positioning system. Thickness mapping and defect detection in metal and composite structures have been performed. A local thickness map in the order of 1 mm has been obtained through a fast-scanning process with comparable resolution to conventional inspection techniques. Overall, it is currently concluded that the proposed NDT scanner is a promising tool that potentially can reduce the inspection time while also having the potential to automate the damage assessment resulting in more efficient MRO inspection processes.

From the article: "To extend the lifetime of products, an agent is connected to the product. This agent has several roles. It depends on the phase of the lifecycle what these roles will be. One of the roles in the usage or recycling phase is to negotiate for buying spare parts in case a part of the product is broken. The same agent can also decide to offer spare parts to other agents to reuse working parts of a broken product. To accomplish this idea, a marketplace for agents has to be set up, where the auctions can take place. To support this concept, blockchain technology has been used. Blockchains are a new type of technology, known from bitcoins, but there are other cases where blockchains can be used. Blockchain is known for its decentralisation, transparency and for making trustful transactions. In this paper the working of different types of blockchains will be briefly explained and determined if they can be useful for online auctions by agents. A prototype of the marketplace using blockchains has been built."

Emotions are a key component of tourism experiences, as emotions make experiences more valued and more memorable. Peak-and-end-theory states that overall experience evaluations are best predicted by the emotions at the most intense and final moments of an experience. Peak-and-end-theory has mostly been studied for relatively simple experiences. Recent insights suggest that peak-and-end-theory does not necessarily hold for tourism experiences, which tend to be more heterogeneous and multi-episodic in nature. Through the novel approach of using electrophysiological measures in combination with experience reconstruction, the applicability of the peak-and-end-theory to the field of tourism is addressed by studying a musical theatre show in a theme park resort. Findings indicate that for a multi-episodic tourism experience, hypotheses from the peak-and-end-theory are rejected for the experience as a whole, but supported for individual episodes within the experience. Furthermore, it is shown that electrophysiology sheds a new light on the temporal dynamics of experience

Purpose – Set in the newly emerging hybrid product research stream, and reflecting trends towards multi-national production and sourcing, this paper aims to present a three-country study on perceived quality and image of automobiles “made in and for” Southeast Asia. Design/methodology/approach – The authors used a multiple cue design in the stimulus definition, reflecting assembly and component origin plus warranty level. Actual car owners were targeted, thereby adding to a relatively low number of studies requiring actual prior purchase. The related face-to-face interviews in the local languages resulted in 720 usable questionnaires. Findings – Country-of-assembly is shown to affect perceived quality as well as perceived image. Warranty extension can moderate the quality effects to some extent, whilst buyers of luxury models display a smaller positive home bias in terms of perceived image than those of non-luxury models. Such home region bias is not demonstrated to be significant for country-of-components. Research limitations/implications – The paper contributes towards ongoing theory-building, especially with regards to an optimum level of origin cue decomposition. It also establishes the importance of adding image perception measurement to the arsenal of origin researchers normally focused on quality effects. Practical implications – Managers need to make strategic decisions on the decomposition of product origin cues, reflecting consumers' abilities to notice several such cues. The selected product origin cues must then be supported with appropriate communications strategies. Originality/value – For the first time, origin effects are demonstrated for the Southeast Asia region. The paper establishes the significance of country-of-target and contributes to research on the ever more complex product origin construct.

In OE a more holistic approach in the design process is needed. This requires a shift of thinking from just the OD to overall goal setting: meeting the functional needs of the patients. This can only be achieved by upgrading the traditional orthopaedic engineering educational programs. Analysing the patient's problem, explicitly formulate OD requirements, the design, the manufacturing, tuning and evaluation must become seamlessly integrated parts of OE education.

Summary Project objectives This study fits into a larger research project on logistics collaboration and outsourcing decisions. The final objective of this larger project is to analyze the logistics collaboration decision in more detail to identify thresholds in these decisions. To reach the overall objectives, the first step is to get a clearer picture on the chemical and logistics service providers industry, sectors of our study, and on logistics collaboration in these sectors. The results of this first phase are presented in this report. Project Approach The study consists of two parts: literature review and five case studies within the chemical industry. The literature covers three topics: logistics collaboration, logistics outsourcing and purchasing of logistics services. The five case studies are used to refine the theoretical findings of the literature review. Conclusions Main observations during the case studies can be summarized as follows: Most analyzed collaborative relationships between shippers and logistics service providers in the chemical industry are still focused on operational execution of logistics activities with a short term horizon. Supply management design and control are often retained by the shippers. Despite the time and cost intensive character of a logistics service buying process, shippers tendering on a very regular basis. The decision to start a new tender project should more often be based on an integral approach that includes all tender related costs. A lower frequency of tendering could create more stability in supply chains. Beside, it will give both, shippers and LSPs, the possibility to improve the quality of the remaining projects. Price is still a dominating decision criterion in selecting a LSP. This is not an issue as long as the comparison of costs is based on an integral approach, and when shippers balance the cost criterion within their total set of criteria for sourcing logistics services. At the shippers' side there is an increased awareness of the need of more solid collaboration with logistics service providers. Nevertheless, in many cases this increased awareness does not actually result in the required actions to establish more intensive collaboration. Over the last years the logistics service providers industry was characterized by low profit margins, strong fragmentation and price competition. Nowadays, the market for LSPs is changing, because of an increasing demand for logistics services. To benefit from this situation a more pro-active role of the service providers is required in building stronger relationships with their customers. They should pay more attention on mid and long term possibilities in a collaborative relation, in stead of only be focused on running the daily operation.
