This article reports on a post hoc study using a randomised controlled trial with 31,842 students in the Netherlands and an instrument consisting of 21 paired problems. The trial showed a variability in the differences of students’ results in solving contextual mathematical problems with either a descriptive or a depictive representation of the problem situation. In this study the relation between this variability and two task characteristics is investigated: (1) complexity of the task representation; and (2) the content domain of the task. We found indications that differences in performance on descriptive and depictive representations of the problem situation are related to the content domain of the problems. One of the tentative conclusions is that for depicted problems in the domain of measurement and geometry the inferential step from representation of the problem situation to the mathematical problem to be solved is smaller than for word problems.

During the timespan of the implementation of a system, the why and what against the actual state of the system can change. This difference is referred to as the design problem. Currently, no design problems are identified in Business Rules Management (BRM) and Business Rules Management System (BRMS) literature. To solve problems with a BRMS implementation it is important that the problems solved by this implementation are known, which is not the case. A case study approach is utilized containing two phases of data collection. Phase one consisted of multiple expert interviews focused on creating a set of design problems utilizing existing literature on BRMS design problems. Then, in phase two, the set of design problems were proposed to a selection of thirteen organizations, which indicated if the design problems occurred in a BRMS implementation. This resulted in a set of 24 design problems. The identification of design problems contributes to future research in evaluating BRMS’s. Furthermore, the identification of design problems is a contribution towards situational artifact construction in the field of BRM.

Little research exists on what works in the supervision of offenders with debt problems. This qualitative study aims to provide insight into the barriers probation officers and clients experience during supervision regarding debt and the support that clients need. Interviews were conducted with 33 Dutch probation officers and 16 clients. The results show that debt often negatively influences clients’ lives and hinders their resocialization. Probation officers lack effective methods to support clients with debt problems. To adequately help clients with debt problems, probation officers should obtain more knowledge about effective interventions and collaborate more closely with debt specialists from the probation supervision outset.
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
Een vraagarticulatieproces met projectmanagers en -leiders uit private en Triple-Helix organisaties laat zien dat zij behoefte hebben aan tools voor: 1. Het bepalen van de juiste incentives om stakeholders actief te betrekken in multi-sector collaboratieve innovatieprojecten (verder verwezen als innovatieprojecten), en 2. Het concreet, transparant en op één lijn te krijgen van de belangen van de partners. Vandaar dat dit project betreft het doorontwikkelen van het Degrees of Engagement diagram (DoE-diagram), een tool voor het managen van stakeholder engagement in innovatieprojecten voor het behalen van de maatschappelijke opgaven. Hiermee sluit het project aan bij de programmalijn ‘rollen, belangen en coördinatie’ van de Kennis en Innovatieagenda van de missie Maatschappelijke Verdienvermogen- thema’s Klimaat & Energie en Circulaire economie. Het consortium bestaat uit de Hogeschool van Amsterdam (HvA), KplusV en Amsterdam Smart City (ASC). De HvA ontwikkelde het DoE-diagram. Voor het identificeren van stakeholders bevat het DoE-diagram attributen op project- en organisatieniveau. In dit project wordt het DoE doorontwikkeld door onderzoek te doen naar: 1. De attributen op individuniveau en potentiele nieuwe attributen op project- en organisatieniveau, 2. De mate waarin deze attributen invloed hebben op het bepalen van de passende incentives, de concretisering van de partnerbelangen en al dan niet succesvolle verloop van innovatieprojecten, 3. Een verkenning van een digitale versie van het DoE voor het managen van in- en uitstappen van partners. Hiermee beoogt het project twee doelen: 1. Inzicht verkrijgen in stakeholderconfiguraties voor het ondersteunen van beslissingen met betrekking tot stakeholder-engagement, 2. Bouwen van een consortium van partijen die vervolg aan het project gaan geven door longitudinaal onderzoek te doen naar de inzet van de uitbreiding van het DoE-diagram en het maken van een werkend prototype en testen van de digitale versie ervan.
Physical rehabilitation programs revolve around the repetitive execution of exercises since it has been proven to lead to better rehabilitation results. Although beginning the motor (re)learning process early is paramount to obtain good recovery outcomes, patients do not normally see/experience any short-term improvement, which has a toll on their motivation. Therefore, patients find it difficult to stay engaged in seemingly mundane exercises, not only in terms of adhering to the rehabilitation program, but also in terms of proper execution of the movements. One way in which this motivation problem has been tackled is to employ games in the rehabilitation process. These games are designed to reward patients for performing the exercises correctly or regularly. The rewards can take many forms, for instance providing an experience that is engaging (fun), one that is aesthetically pleasing (appealing visual and aural feedback), or one that employs gamification elements such as points, badges, or achievements. However, even though some of these serious game systems are designed together with physiotherapists and with the patients’ needs in mind, many of them end up not being used consistently during physical rehabilitation past the first few sessions (i.e. novelty effect). Thus, in this project, we aim to 1) Identify, by means of literature reviews, focus groups, and interviews with the involved stakeholders, why this is happening, 2) Develop a set of guidelines for the successful deployment of serious games for rehabilitation, and 3) Develop an initial implementation process and ideas for potential serious games. In a follow-up application, we intend to build on this knowledge and apply it in the design of a (set of) serious game for rehabilitation to be deployed at one of the partners centers and conduct a longitudinal evaluation to measure the success of the application of the deployment guidelines.
