Purpose – purpose of this article is to report about the progress of the development of a method that makes sense of knowledge productivity, in order to be able to give direction to knowledge management initiatives. Methodology/approach – the development and testing of the method is based on the paradigm of the Design Sciences. In order to increase the objectivity of the research findings, and in order to test the transferability of the method, this article suggests a methodology for beta testing. Findings – based on the experiences within this research, the concept of beta testing seems to fit Design Science Research very well. Moreover, applying this concept within this research resulted in valuable findings for further development of the method. Research implications – this is the first article that explicitly applies the concept of beta testing to the process of developing solution concepts. Originality/value – this article contributes to the further operationalization of the relatively new concept of knowledge productivity. From a methodological point of view, this article aims to contribute to the paradigm of the Design Sciences in general, and the concept of beta testing in particular.

Oscillatory neural dynamics have been steadily receiving more attention as a robust and temporally precise signature of network activity related to language processing. We have recently proposed that oscillatory dynamics in the beta and gamma frequency ranges measured during sentence-level comprehension might be best explained from a predictive coding perspective. Under our proposal we related beta oscillations to both the maintenance/change of the neural network configuration responsible for the construction and representation of sentence-level meaning, and to top-down predictions about upcoming linguistic input based on that sentence-level meaning. Here we zoom in on these particular aspects of our proposal, and discuss both old and new supporting evidence. Finally, we present some preliminary magnetoencephalography data from an experiment comparing Dutch subject- and object-relative clauses that was specifically designed to test our predictive coding framework. Initial results support the first of the two suggested roles for beta oscillations in sentence-level language comprehension.

While the original definition of replacement focuses on the replacement of the use of animals in science, a more contemporary definition focuses on accelerating the development and use of predictive and robust models, based on the latest science and technologies, to address scientific questions without the use of animals. The transition to animal free innovation is on the political agenda in and outside the European Union. The Beyond Animal Testing Index (BATI) is a benchmarking instrument designed to provide insight into the activities and contributions of research institutes to the transition to animal free innovation. The BATI allows participating organizations to learn from each other and stimulates continuous improvement. The BATI was modelled after the Access to Medicine Index, which benchmarks pharmaceutical companies on their efforts to make medicines widely available in developing countries. A prototype of the BATI was field-tested with three Dutch academic medical centers and two universities in 2020-2021. The field test demonstrated the usability and effectiveness of the BATI as a benchmarking tool. Analyses were performed across five different domains. The participating institutes concluded that the BATI served as an internal as well as an external stimulus to share, learn, and improve institutional strategies towards the transition to animal free innovation. The BATI also identified gaps in the development and implementation of 3R technologies. Hence, the BATI might be a suitable instrument for monitoring the effectiveness of policies. BATI version 1.0 is ready to be used for benchmarking at a larger scale.

Size measurement plays an essential role for micro-/nanoparticle characterization and property evaluation. Due to high costs, complex operation or resolution limit, conventional characterization techniques cannot satisfy the growing demand of routine size measurements in various industry sectors and research departments, e.g., pharmaceuticals, nanomaterials and food industry etc. Together with start-up SeeNano and other partners, we will develop a portable compact device to measure particle size based on particle-impact electrochemical sensing technology. The main task in this project is to extend the measurement range for particles with diameters ranging from 20 nm to 20 um and to validate this technology with realistic samples from various application areas. In this project a new electrode chip will be designed and fabricated. It will result in a workable prototype including new UMEs (ultra-micro electrode), showing that particle sizing can be achieved on a compact portable device with full measuring range. Following experimental testing with calibrated particles, a reliable calibration model will be built up for full range measurement. In a further step, samples from partners or potential customers will be tested on the device to evaluate the application feasibility. The results will be validated by high-resolution and mainstream sizing techniques such as scanning electron microscopy (SEM), dynamic light scattering (DLS) and Coulter counter.
Lab-on-a-Chip (LOC) devices worden op dit moment voor het overgrote deel in de wetenschap toegepast, in laboratoria met apparatuur die daar gebruikelijk is. LOC-devices hebben echter een grote potentie buiten de laboratoria, in bijvoorbeeld Point-Of-Care Testing situaties in de gezondheidszorg, en het verrichten van metingen ter plaatse t.b.v. de voedsel- en watersector. Ook in andere applicatievelden zoals forensisch recherchewerk, en environmental monitoring kunnen LOC devices een enorme impact hebben. Voorwaarde is wel dat zij hanteerbaarder, goedkoper en robuuster worden, en qua productiewijze minder gecompliceerd. De ontwikkeling van de huidige LOCs vereist een aanzienlijke investering om tot een werkend en betrouwbaar product te komen. Traditioneel wordt hierbij gebruikt gemaakt van kostbare fotolithografische technieken in combinatie met chemisch etsen in zogenoemde cleanrooms. Dit maakt de initiële drempel voor nieuwe toepassingen extreem hoog. Daarnaast is de apparatuur om deze chips aan te sluiten, aan te sturen en een meting te verrichten in veel gevallen zeer specialistisch en daardoor blijft de inzet van deze technologie beperkt tot een goed geoutilleerd lab. Met het LOC2Use project van Saxion lectoraten NanoBio en Industrial Design in samenwerking met het bedrijfsleven wordt beoogd om de LOC-technologie uit het lab te halen, door technologische toepassingen te ontwikkelen op basis van meer toegankelijke technologie. Vertrekpunt voor de toepassingen zijn de use-cases, die in samenwerking met stakeholders en MKB-partners in verschillende toepassingsgebieden worden opgesteld. Beoogd resultaat is een catalogus vol met getoetste technische oplossingen, gekoppeld aan de eisen uit de use-cases. Aan de hand van de gevonden technologische oplossingen worden een viertal illustratieve cases uitgewerkt. En worden er uit de catalogus een aantal bruikbare technologische bouwstenen geselecteerd voor rapid prototyping en kleine series microfluidic devices in een FabLab omgeving, een eerste stap in de richting van een LOC-fieldlab. Met dit project wordt LOC betaalbaar en breder toepasbaar voor het MKB.
