Op basis van een cross-sectioneel onderzoek onder deelnemers aan een hardloopevenement worden verschillen tussen snelle en langzame hardlopers onderzocht. Verschillen in motieven voor hardlopen en ervaren belang van app functionaliteiten werden in kaart gebracht. Ook werd gekeken naar verschillen in hun intentie om te blijven hardlopen, hoe apps gebruikt worden en verwachte effecten van app gebruik.
In physiotherapy practice, the use of Artificial Intelligence (AI) is becoming increasingly common. For instance, you may be familiar with STarT Back Tool, a decision-support model designed for individuals with low back pain.1 This model can assess risks and recommends the most appropriate treatment while enhancing clients’ self-management. However, the use of AI also raises ethical questions. In this editorial we explore these ethical questions through a moral case deliberation that, while still futuristic, is rapidly approaching reality. n this editorial, we explore ethical issues regarding AI in physiotherapy. We do so through the lens of the sports medicine dialogue, a method for moral case deliberation that supports a care-ethical approach for physiotherapists and sport physicians.3 This method employs the metaphor of a sports match: itandapos;s about winning and losing, the players on the field, as well as the broader context in which the game takes place. In this method, we evaluate the perspectives of all those involved in the sport match regarding a central question. The central question that is deliberated is: “What is at stake?”.3 By use of the sports metaphor we are invited to look at an ethical question from multiple perspectives, delay our primary reactions and simplify difficult ethical problems such as the usage of AI.

Each of us has a story that comes alive as we wake up in the morning, develops throughout the day, and holds layers of meaning as we lay our heads down at night – it might be called a narrative of our identity. When loss occurs, our story fragments into unfamiliar pieces, and who we identify as becomes scattered – sometimes even shattered. We must work to reconstruct meaning in our lives and to rebuild our identity. As leading author on this editorial, with an article of my own in this issue, I confronted this when my father died. I felt his story slipping away, becoming blurred, forgotten, and for some, erased – and the same held true for me. The chaos of my shattered identity exacerbated the deep pain of losing him and I experienced complicated grief. I had to reshape my narrative to remember the authentic parts of me and rebuild a new self in a fatherless world. This journey is in part what motivated me to become a symposium co-editor for the journal. All four of us editors of this special issue have experienced “living with loss” following the premature loss of either our father or spouse, and I wanted to see what lived experience and knowledge we could bring to the readers about loss in the fields of both guidance and counselling.

In this proposal, a consortium of knowledge institutes (wo, hbo) and industry aims to carry out the chemical re/upcycling of polyamides and polyurethanes by means of an ammonolysis, a depolymerisation reaction using ammonia (NH3). The products obtained are then purified from impurities and by-products, and in the case of polyurethanes, the amines obtained are reused for resynthesis of the polymer. In the depolymerisation of polyamides, the purified amides are converted to the corresponding amines by (in situ) hydrogenation or a Hofmann rearrangement, thereby forming new sources of amine. Alternatively, the amides are hydrolysed toward the corresponding carboxylic acids and reused in the repolymerisation towards polyamides. The above cycles are particularly suitable for end-of-life plastic streams from sorting installations that are not suitable for mechanical/chemical recycling. Any loss of material is compensated for by synthesis of amines from (mixtures of) end-of-life plastics and biomass (organic waste streams) and from end-of-life polyesters (ammonolysis). The ammonia required for depolymerisation can be synthesised from green hydrogen (Haber-Bosch process).By closing carbon cycles (high carbon efficiency) and supplementing the amines needed for the chain from biomass and end-of-life plastics, a significant CO2 saving is achieved as well as reduction in material input and waste. The research will focus on a number of specific industrially relevant cases/chains and will result in economically, ecologically (including safety) and socially acceptable routes for recycling polyamides and polyurethanes. Commercialisation of the results obtained are foreseen by the companies involved (a.o. Teijin and Covestro). Furthermore, as our project will result in a wide variety of new and drop-in (di)amines from sustainable sources, it will increase the attractiveness to use these sustainable monomers for currently prepared and new polyamides and polyurethanes. Also other market applications (pharma, fine chemicals, coatings, electronics, etc.) are foreseen for the sustainable amines synthesized within our proposition.
Single-Use Plastics (SUPs) are at the centre of European Union Agenda aiming at reducing the plastic soup with the EU Directive 2019/904. SUPs reduction is pivotal also in the Dutch Government Agenda for the transition to a Circular Economy by 2050. Worldwide the data on SUPs use and disposal are impressive: humans use around 1.2 million plastic bottles per minute; approximately 91% of plastic is not recycled (www.earthday.org/fact-sheet-single-use-plastics/). While centralised processes of waste collection, disposal, and recycling strive to cope with such intense use of SUPs, the opportunities and constraints of establishing a networked grid of facilities enacting processes of SUPs collection and recycling with the active involvement of local community has remained unexplored. The hospitality sector is characterised by a widespread capillary network of small hospitality firms nested in neighbourhoods and rural communities. Our research group works with small hospitality firms, different stakeholders, and other research groups to prompt the transition of the hospitality sector towards a Circular Economy embracing not only the environmental and economic dimensions but also the social dimension. Hence, this project explores the knowledge and network needed to build an innovative pilot allowing to close the plastic loop within a hospitality facility by combining a 3D printing process with social inclusiveness. This will mean generating key technical and legal knowledge as well as a network of strategic experts and stakeholders to be involved in an innovative pilot setting a 3D printing process in a hospitality facility and establishing an active involvement of the local community. Such active involvement of the local inhabitants will be explored as SUPs collectors and end-users of upcycled plastics items realised with the 3D printer, as well as through opportunities of vocational training and job opportunities for citizens distant from the job market.
De achtergrond van het project is het hoogwaardig recyclen van (autobanden)rubbers die het eind van de gebruiksfase hebben bereikt en worden aangemerkt als ‘afval’. In het beoogde proces van hoogwaardige recycling wordt het materiaal middels devulcanisatie zo ver mogelijk teruggebracht tot zijn oorspronkelijke vorm, waardoor de eigenschappen van de elastomeren grotendeels behouden blijven. Het doel is dat het materiaal bij hergebruik als wezenlijk deel van de samenstelling van een nieuw te vervaardigen rubbercompound kan dienen. Beoogde toepassing is terug in banden, dus een cradle-to-cradle loop. Naast het behoud van de unieke rubbereigenschappen is met name de homogeniteit van het materiaal en herverwerkbaarheid van belang. Tevens is het belangrijk dat de kosten van het devulcanisatieproces relatief laag zijn om het economisch aantrekkelijk te maken. De nieuwe methode van recycling past in het principe van de circulaire economie. Het onderhavige project beoogt de praktische vertaling van de kennis die ontwikkeld is in het PhD-onderzoeksproject ‘Closing the Loop’ van de Universiteit Twente in samenwerking met Hogeschool Windesheim naar een tweetal bestaande materiaalstromen. De kennis is opgebouwd voor een specifieke materiaalstroom van een specifieke leverancier, maar is naar verwachting breder inzetbaar voor meerdere materiaalstromen door aanpassing van de procesparameters. Onderdeel van het onderzoek is het analyseren van de kwaliteit van het gedevulcaniseerde materiaal en daarnaast het testen van de eigenschappen van het materiaal na toevoeging van een standaard vulcanisatiesysteem en het bijbehorende vulcanisatieproces. Het onderzoek wordt gedaan door deskundigen in het vakgebied die specifiek kennis en ervaring hebben met betrekking tot rubbermaterialen en -verwerking en recyclingvraagstellingen omtrent rubbers. Er zijn een tweetal MKB-bedrijven bij het project betrokken die jarenlange ervaring hebben met de recycling van rubbers. Daarnaast is RecyBEM, de uitvoeringsorganisatie van het Besluit beheer autobanden (Bba) betrokken bij dit project. RecyBEM organiseert sinds 2004 in Nederland de inzameling en recycling van gebruikte autobanden uit de vervangingsmarkt. Het beoogde projectresultaat betreft kennis over de technische en praktische mogelijkheden van het devulcanisatieproces voor rubber afvalstromen. Om de mogelijkheden van hoogwaardig hergebruik van deze rubbers nauwkeurig te bepalen en kunnen voorspellen worden de materialen tevens opnieuw gecompoundeerd en geanalyseerd. De opgedane kennis en resultaten worden gerapporteerd in een onderzoeksrapport. Tevens zal met instemming van de deelnemende bedrijven hierover een artikel worden geschreven.
