De twee onderzoeksvragen die de basis waren voor dit onderzoek zijn: Kunnen opleiders in het beroepsonderwijs 'negotiation of meaning' van studenten stimuleren door 'contingent modelling' en is deze stimulering positief gerelateerd aan de ontwikkeling van de persoonlijke theorieën van mbo-studenten? Deze vragen werden onderzocht door middel van een quasi-experimenteel onderzoek bestaande uit drie componenten: een lessenserie, een voor- en nameting en het onderscheid tussen een 'contingent modelling' conditie en een studentconditie. De onderzoekers concluderen uit de resultaten dat persoonlijke werktheorieën stabiel zijn en dus moeilijk te stimuleren.

Leden van de kenniskring “Professionalisering van Leraren en Lerarenopleiders” (Fontys Lerarenopleiding Tilburg) zijn voornemens een intervisiegroep op te zetten waarin opleiders met elkaar van gedachten wisselen over het begrip modelling: het voordoen, expliciteren en legitimeren van wat het zou kunnen betekenen om docent te zijn en bepaalde didactische en pedagogische keuzes te maken. Aan de hand van een door Powell (2015) opgesteld kijkkader willen zij zich ontwikkelen in hun professionele rol als “leraar van leraren”. Hoe deze intervisiegroep te werk gaat, wie er aan deelnemen, welke vragen en dilemma’s centraal staan, en wat de beoogde of mogelijk onverwachte leeropbrengsten kunnen zijn, zal in deze bijeenkomst samen met de aanwezige congresdeelnemers verkend worden. Uitwisseling van ervaringen met modelling en met professionele ontwikkeling op dit gebied zullen centraal staan; congresdeelnemers worden van harte uitgenodigd hun praktijkvoorbeelden te delen. Doel van de bijeenkomst is te komen tot een concretere invulling van dit intervisietraject, waarmee opleiders in hun eigen context aan de slag kunnen.

Player behavioural modelling has grown from a means to improve the playing strength of computer programs that play classic games (e.g., chess), to a means for impacting the player experience and satisfaction in video games, as well as in cross-domain applications such as interactive storytelling. In this context, player behavioural modelling is concerned with two goals, namely (1) providing an interesting or effective game AI on the basis of player models and (2) creating a basis for game developers to personalise gameplay as a whole, and creating new user-driven game mechanics. In this article, we provide an overview of player behavioural modelling for video games by detailing four distinct approaches, namely (1) modelling player actions, (2) modelling player tactics, (3) modelling player strategies, and (4) player profiling. We conclude the article with an analysis on the applicability of the approaches for the domain of video games.

Positive Energy Districts (PEDs) have the potential of accelerating the decarbonization of urban areas and promoting scalability between cities. The development and real-world implementation of such innovative concepts can be enhanced through urban energy modelling. However, assessing PEDs can be challenging, and information on this topic is scarce and fragmented. The main contribution of this paper is collecting and analyzing challenges and limitations of energy modelling software for assessing PEDs through five case studies in Italy, Spain, The Netherlands, Denmark and Canada. Case studies are assessed first from a modelling approach, then the main identified challenges and limitations of modelling tools for PEDs are discussed, and finally, various ongoing trends and research needs in this field are suggested.

BackgroundScientific software incorporates models that capture fundamental domain knowledge. This software is becoming increasingly more relevant as an instrument for food research. However, scientific software is currently hardly shared among and (re-)used by stakeholders in the food domain, which hampers effective dissemination of knowledge, i.e. knowledge transfer.Scope and approachThis paper reviews selected approaches, best practices, hurdles and limitations regarding knowledge transfer via software and the mathematical models embedded in it to provide points of reference for the food community.Key findings and conclusionsThe paper focusses on three aspects. Firstly, the publication of digital objects on the web, which offers valorisation software as a scientific asset. Secondly, building transferrable software as way to share knowledge through collaboration with experts and stakeholders. Thirdly, developing food engineers' modelling skills through the use of food models and software in education and training.

Three empirical models were used to fit the formation of acrylamide in crisps of three different cold-sweetened potato genotypes, fried under the same experimental conditions. Statistical methods were used to compare the performance of the models, with the "Logistic-Exponential" model performing the best. The obtained model parameters for the formation of acrylamide showed improvement in precision compared to an earlier study, the precision of the parameter estimates for the degradation of acrylamide was still problematic. Nevertheless, the predictive capacity of the "Logistic-Exponential" model was tested, as this model showed a strong correlation between parameter a and the reducing sugar content of the raw potato. The predictions from this model for the formation of acrylamide in potato crisps were close to earlier reported experimental values. Therefore, the use of the "Logistic-Exponential" model as a tool to predict acrylamide in potato crisps seems promising and should be developed further.

Damping constitutes a major source of uncertainty in dynamic analysis and an open issue to experimental and analytical research. After a thorough review of the current views and approaches existing in literature on damping and its appropriate modelling, this paper focuses on the implications of the available modelling options on analysis. As result of a series of considerations, a damping modelling solution for nonlinear dynamic analyses of cantilever RC walls is suggested within the frame of Direct Displacement-Based Design, supported by comparative analyses on wall structures.

The viability of novel network-level circular business models (CBMs) is debated heavily. Many companies are hesitant to implement CBMs in their daily practice, because of the various roles, stakes and opinions and the resulting uncertainties. Testing novel CBMs prior to implementation is needed. Some scholars have used digital simulation models to test elements of business models, but this this has not yet been done systematically for CBMs. To address this knowledge gap, this paper presents a systematic iterative method to explore and improve CBMs prior to actual implementation by means of agent-based modelling and simulation. An agent-based model (ABM) was co-created with case study participants in three Industrial Symbiosis networks. The ABM was used to simulate and explore the viability effects of two CBMs in different scenarios. The simulation results show which CBM in combination with which scenario led to the highest network survival rate and highest value captured. In addition, we were able to explore the influence of design options and establish a design that is correlated to the highest CBM viability. Based on these findings, concrete proposals were made to further improve the CBM design, from company level to network level. This study thus contributes to the development of systematic CBM experimentation methods. The novel approach provided in this work shows that agent-based modelling and simulation is a powerful method to study and improve circular business models prior to implementation.

Diet related non-communicable diseases (NCDs), as well as micronutrient deficiencies, are of widespread and growing importance to public health. Authorities are developing programs to improve nutrient intakes via foods. To estimate the potential health andeconomic impact of these programs there is a wide variety of models. The aim of this review is to evaluate existing models to estimate the health and/or economic impact of nutrition interventions with a focus on reducing salt and sugar intake andincreasing vitamin D, iron, and folate/folic acid intake. The protocol of this systematic review has been registered with the International Prospective Register of Systematic Reviews (PROSPERO: CRD42016050873). The final search was conducted onPubMed and Scopus electronic databases and search strings were developed for salt/sodium, sugar, vitamin D, iron, and folic acid intake. Predefined criteria related to scientific quality, applicability, and funding/interest were used to evaluate the publications. In total 122 publications were included for a critical appraisal: 45 for salt/sodium, 61 for sugar, 4 for vitamin D, 9 for folic acid, and 3 for iron. The complexity of modelling the health and economic impact of nutrition interventions is dependent on the purpose and data availability. Although most of the models have the potential to provide projections of future impact, the methodological challenges are considerable. There is a substantial need for more guidance and standardization for future modelling, to compare results ofdifferent studies and draw conclusions about the health and economic impact of nutrition interventions.

Het business model canvas is het afgelopen decennium populair geworden voor de ontwikkeling van organisaties en om ondernemerschap te faciliteren. Het model is ook in het hoger onderwijs populair als methode om te leren ondernemen. De populariteit neemt niet weg dat er vragen zijn over de effectiviteit van business modelling en de wijze waarop de aanpak het beste ingezet kan worden. In dit artikel brengen we deze ontwikkelingen samen door te laten zien hoe business modelling op vier verschillende manieren gebruikt kan worden voor het faciliteren van lerend ondernemerschap en het creëren van een lerende onderneming.
