Met alle maatschappelijke weerstand tegen ‘verdozing’ van het Nederlandse landschap, verwacht men een halt op de ontwikkeling van logistiek vastgoed. Echter, het opslagvolume voor stilstaande goederen blijft toenemen en de vraag naar de redelijkheid daarvan dient zich op. Aangezien deze - min of meer autonome - systeemontwikkeling exact volgens de techologiefilosofie van Jacques Ellul verloopt, wordt zijn theorie gebruikt om het publieke debat over dit thema te analyseren. Hieruit blijkt dat de argumenten tégen grote distributiecentra met name een morele toon hebben, terwijl de argumenten vóór vooral een technische (efficiëntie-)logica volgen. Daarmee wordt het debat niet in gelijke termen gevoerd. De conclusie van dit artikel is dat de redelijkheid van 'verdozing' meer over ethiek dan over efficiëntie gaat. Waaruit een nadrukkelijk advies voor de logistieke wereld volgt om diepgaand onderzoek te doen naar de morele waarden die het nastreeft.

De HvA heeft voor de periode 2018-2021 ‘aansluitgelden’ van OCW ontvangen om de aansluiting van vo en mbo met het hoger onderwijs te verbeteren. Het HvA-netwerk aansluiting dat toen is opgestart, heeft diverse projecten uitgevoerd. Met dit praktijkonderzoek wordt in kaart gebracht welke aansluitingsprojecten hebben plaatsgevonden en wat we hiervan kunnen leren voor de toekomst. In 2021 heeft het Lectoraat Kansrijke Schoolloopbanen in een Diverse Stad hiertoe 17 interviews afgenomen waarin 22 aansluitingsprojecten zijn besproken, zowel HvA-breed als op faculteitsniveau. Bij alle interviews is gebruik gemaakt van de CIMO-logica (in het Nederlands CIMU). Een Interventie in een bepaalde Context leidt, door het triggeren van een Mechanisme, tot een bepaalde voorspelbare Uitkomst (Outcome). Door de aansluitingsprojecten te analyseren aan de hand van de CIMO-logica kunnen elementen die transfereerbaar zijn gedeeld worden met andere (toekomstige) projecten.--The AUAS has received 'connection fees' from OCW for the 2018-2021 period to support the connection of secondary education and MBO with higher education. The AUAS network connection that was started up at that time has carried out various projects. This research maps out which connection projects have taken place and what we can learn from them for the future. To this end, the Lectoraat Promising School Careers in a Diverse City conducted 17 interviews in which 22 connection projects were discussed, both AUAS-wide and at faculty level. With all interviews, the CIMO logic was used: an Intervention in a certain Context leads, by triggering a Mechanism, to a certain predictable Outcome. By analyzing the connection projects using the CIMO logic, elements that can be transferred are shared with other (future) projects.
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.
Our unilateral diet has resulted in a deficiency of specific elements/components needed for well-functioning of the human body. Especially the element magnesium is low in our processed food and results in neuronal and muscular malfunctioning, problems in bone heath/strength, and increased chances of diabetes, depression and cardiovascular diseases. Furthermore, it has also been recognized that magnesium plays an important role in cognitive functioning (impairment and enhancement), especially for people suffering from neurodegenerative diseases (Parkinson disease, Alzheimer, etc). Recently, it has been reported that magnesium addition positively effects sleep and calmness (anti-stress). In order to increase the bioavailability of magnesium cations, organic acids such as citrate, glycerophosphate and glycinate are often used as counterions. However, the magnesium supplements that are currently on the market still suffer from low bio-availability and often do not enter the brain significantly.The preparation of dual/multiple ligands of magnesium in which the organic acid not only functions as a carrier but also has synergistically/complementary biological effects is widely unexplored and needs further development. As a result, there is a strong need for dual/multiple magnesium supplements that are non-toxic, stable, prepared via an economically and ecologically attractive route, resulting in high bioavailability of magnesium in vivo, preferably positively influencing cognition/concentration
The focus of this project is on improving the resilience of hospitality Small and Medium Enterprises (SMEs) by enabling them to take advantage of digitalization tools and data analytics in particular. Hospitality SMEs play an important role in their local community but are vulnerable to shifts in demand. Due to a lack of resources (time, finance, and sometimes knowledge), they do not have sufficient access to data analytics tools that are typically available to larger organizations. The purpose of this project is therefore to develop a prototype infrastructure or ecosystem showcasing how Dutch hospitality SMEs can develop their data analytic capability in such a way that they increase their resilience to shifts in demand. The one year exploration period will be used to assess the feasibility of such an infrastructure and will address technological aspects (e.g. kind of technological platform), process aspects (e.g. prerequisites for collaboration such as confidentiality and safety of data), knowledge aspects (e.g. what knowledge of data analytics do SMEs need and through what medium), and organizational aspects (what kind of cooperation form is necessary and how should it be financed).
