Abstract. In recent years circular economy has become more important for the development of many places including cities. Traditionally, urban development policies have mainly been aiming to improve the socio-economic wellbeing of neighbourhoods. However, technical and ecologic aspects have their effects too and need to go hand in hand. This paper is based on an urban area experiment in the Dutch city of Utrecht. In order to assess urban area developments, typically rather straight-forward quantitative indicators have been used. However, it has proved more complicated to assess multifaceted developments of the area studied in this paper. With the City Model Canvas a multi-layered model is being used to better assess the impact of the urban development being studied. Key findings include that the project studied resulted in more space for companies from the creative industry and the settlement of local ‘circular’ entrepreneurs and start-ups, although it remains unclear to what extent these benefit from each other’s presence. The increase in business activity resulted in more jobs, but it is again unclear whether this led to more social inclusion. From an environmental point of view the project activities resulted in less raw materials being used, although activities and public events bring nuisance to the surrounding neighbourhoods.

An important contribution to the environmental impact of agro-food supply chains is related to the agricultural technology and practices used in the fields during raw material production. This problem can be framed from the point of view of the Focal Company (FC) as a raw material Green Supplier Selection Problem (GSSP). This paper describes an extension of the GSSP methodology that integrates life cycle assessment, environmental collaborations, and contract farming in order to gain social and environmental benefits. In this approach, risk and gains are shared by both parties, as well as information related to agricultural practices through which the FC can optimize global performance by deciding which suppliers to contract, capacity and which practices to use at each supplying field in order to optimize economic performance and environmental impact. The FC provides the knowledge and technology needed by the supplier to reach these objectives via a contract farming scheme. A case study is developed in order to illustrate and a step-by-step methodology is described. A multi-objective optimization strategy based on Genetic Algorithms linked to a MCDM approach to the solution selection step is proposed. Scenarios of optimization of the selection process are studied to demonstrate the potential improvement gains in performance.
Organizations are currently facing substantial challenges regarding becoming circular by 2050 – also referred to as Circular Economy (CE). Subsequently, increasing complexity on all organizational levels creates uncertainty about respective organizational and technological capabilities and adequate strategies to develop these capabilities. Organizations are struggling in picking up the CE ambitions and answering the what’s in it for me question. Scholars are developing models and frameworks to enable organizations to measure CE performance. Over 125 assessment methods are available for micro level assessment – measuring up to 365 different metrics. Moreover, extant literature is available presenting barriers and opportunities for CE transformation focusing on industry, sector, region, etc. And, although a more holistic perspective is required to become circular mature, this is currently lacking. In this paper we present a multi-methodology view on approaches and how they are used (or not). Our main goal is to extend the existing body of knowledge with an eye on applicability and research directions to untie the Gordian knot of measuring circularity.

Multi-Assessment richt zich op meertalig toetsen van nieuwkomers in de rekenles, zowel op taalscholen als op reguliere basisscholen. Door het benutten van thuistalen bij evaluatie, wil Multi-Assessment het potentieel van nieuwkomers beter benutten, waardoor ze betere kansen krijgen in het rekenonderwijs én in hun schoolloopbaan. Het lectoraat Meertaligheid en Onderwijs werkt hierin samen met het Seminarium voor Orthopedagogiek en de lectoraten Toetsing en Beoordeling in Beroepsonderwijs en Wiskundig en Analytisch Vermogen van Professionals.Doel In het Multi-Assessment-project beogen we alternatieve toetsvormen (summatief en formatief) te ontwikkelen en te beproeven, in samenwerking met onderwijsprofessionals. Maatschappelijke en wetenschappelijke partners denken met ons mee. In de beoogde aanpak is het benutten van thuistalen een centraal uitgangspunt. Resultaten Inzicht in toetsvormen die zowel de prestaties als het potentieel van nieuwkomers beter in beeld brengen dan tot dusver het geval is Inspirerende voorbeelden en beschrijvingen van meertalige toetsvormen Inzicht in kansen en obstakels die onderwijsprofessionals ervaren bij meertalig toetsen van nieuwkomers Aanpassingen in het curriculum van de Master Educational Needs (SVO), op grond van de bevindingen Looptijd 01 september 2021 - 31 augustus 2023 Aanpak In de eerste fase van het project neemt een groep onderwijsprofessionals deel aan een professionaliseringprogramma over meertalig toetsen. In de tweede fase ontwikkelen onderwijsprofessionals alternatieve toetsvormen om direct op school te gebruiken, in samenwerking met de betrokken onderzoekers.
