De tweedegraads lerarenopleiding van Hogeschool Utrecht (HU) maakt bij het Samen Opleiden gebruik van leernetwerken. Om inzicht te krijgen in de vormgeving van de leernetwerken, de rol van de opleider binnen de leernetwerken en het welbevinden en de competentieontwikkeling van studenten zijn interviews afgenomen bij de grondleggers, de opleiders en de studenten van zes schoolbesturen. Deze zijn verder geanalyseerd vanuit de CIMO-logica. Deze samenvatting focust zich op de inrichting van de leernetwerken, ervaringen van studenten en aanbevelingen. Zie het onderzoeksrapport voor het volledige onderzoek met een uitbereide toelichting van de methode.
1e alinea column: Hoe ziet innovatie in de digital age eruit? Anders dan daarvoor? Is succes van innovatie in de digital age wel voorspelbaar? Bestaat er zoiets als een business logica voor innovatie? Voor echt nieuwe business is dat maar heel beperkt zo. Er zijn geen marktvoorbeelden waar je naar kunt kijken. Concurrenten of collega’s zijn je niet voorgegaan en hoe de klant zal reageren is ook al een verrassing.

Toekomstige professionals moeten complexe problemen kunnen oplossen. Hoeleren we dit hbo-studenten? Design thinking en ontwerpgericht onderzoek bieden beiden dezelfde logica voor het ontwerpen van onderbouwde oplossingenvoor complexe problemen. Ze verschillen in accent, met name in inhoudelijke uitgangspunten en de organisatie van het ontwerpproces. Zowel design thinkingals ontwerpgericht onderzoek zijn geschikt voor het oplossen van complexeproblemen, zeker als hun sterke punten in opeenvolgende ontwerpcycli wordengecombineerd.
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).
