Particle verbs (e.g., look up) are lexical items for which particle and verb share a single lexical entry. Using event-related brain potentials, we examined working memory and long-term memory involvement in particle-verb processing. Dutch participants read sentences with head verbs that allow zero, two, or more than five particles to occur downstream. Additionally, sentences were presented for which the encountered particle was semantically plausible, semantically implausible, or forming a non-existing particle verb. An anterior negativity was observed at the verbs that potentially allow for a particle downstream relative to verbs that do not, possibly indexing storage of the verb until the dependency with its particle can be closed. Moreover, a graded N400 was found at the particle (smallest amplitude for plausible particles and largest for particles forming non-existing particle verbs), suggesting that lexical access to a shared lexical entry occurred at two separate time points.

Chronic pain rehabilitation programs are aimed at helping patients to increase their functioning despite being in pain, thereby improving their quality of life. However, conversations between patients and practitioners about how the patient could deal with his/her pain and pain-related disabilities in a different way can be interactionally challenging. This study adopts a discursive psychological perspective to explore how pain-related disability is negotiated by patients and practitioners during consultations. The analysis shows that pain-related disability is treated by both patients and practitioners as negotiable rather than a fixed reality. Moreover, it shows that patients’ and practitioners’ negotiations of disability are subject to issues of agency, accountability, and blame, and it provides insight into the interactional dilemmas that are at stake, both for patients and practitioners. Revalidatieprogramma’s voor patiënten met chronische pijn zijn gericht op het verbeteren van het functioneren ondanks de pijn, waardoor kwaliteit van leven wordt bevorderd. Conversaties tussen patiënten en behandelaars over de manier waarop de patiënt kan omgaan met de pijn en gerelateerde beperkingen kunnen interactionele uitdagingen met zich meebrengen. Dit hoofdstuk verkent vanuit discursief-psychologisch perspectief hoe beperkingen worden onderhandeld door patiënten en behandelaars in consulten. De analyse toont aan dat de beperkingen worden behandeld als onderhandelbaar in plaats van als een onveranderbare werkelijkheid. Bovendien toont de analyse dat in deze onderhandelingen bepaalde issues relevant worden gemaakt, zoals ‘agency’, verantwoordelijkheid en schuld. Inzicht wordt geboden in de interactionele dilemma’s die op het spel staan voor zowel patiënten als behandelaars.

Purpose – To analyse common metaphors used in the intellectual capital (IC) and knowledge management literatures to conceptualise knowledge, in order to study the nature of the intellectual capital concept. Design/methodology/approach – A textual analysis methodology is used to analyse texts from The Knowledge-Creating Company by Nonaka and Takeuchi, Working Knowledge by Davenport and Prusak and “Brainpower” by Stewart, in order to identify underlying metaphors. Findings – Over 95 per cent of the statements about knowledge identified are based on some kind of metaphor. The two dominant metaphors that form the basis for the concept of intellectual capital are “knowledge as a resource” and “knowledge as capital”. Research limitations/implications – Metaphors highlight certain characteristics and ignore others, so the IC community should ask itself what characteristics of knowledge the “knowledge as a resource” and “knowledge as capital” metaphors ignore. Practical implications – Knowledge has no referent in the real world and requires metaphor to be defined, conceptualised, and acted upon. When using such metaphors we should become aware of their limitations as they steer us in certain directions and this may happen unconsciously. The paper concludes by asking whether we need new metaphors to better understand the mechanisms of the knowledge economy, hence allowing us to potentially change some of the more negative structural features of contemporary society. Originality/value – This paper is the first to highlight that intellectual capital is a metaphor and that the metaphorical nature of the concept has far reaching consequences.

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.
The textile and clothing sector belongs to the world’s biggest economic activities. Producing textiles is highly energy-, water- and chemical-intensive and consequently the textile industry has a strong impact on environment and is regarded as the second greatest polluter of clean water. The European textile industry has taken significant steps taken in developing sustainable manufacturing processes and materials for example in water treatment and the development of biobased and recycled fibres. However, the large amount of harmful and toxic chemicals necessary, especially the synthetic colourants, i.e. the pigments and dyes used to colour the textile fibres and fabrics remains a serious concern. The limited range of alternative natural colourants that is available often fail the desired intensity and light stability and also are not provided at the affordable cost . The industrial partners and the branch organisations Modint and Contactgroep Textiel are actively searching for sustainable alternatives and have approached Avans to assist in the development of the colourants which led to the project Beauti-Fully Biobased Fibres project proposal. The objective of the Beauti-Fully Biobased Fibres project is to develop sustainable, renewable colourants with improved light fastness and colour intensity for colouration of (biobased) man-made textile fibres Avans University of Applied Science, Zuyd University of Applied Sciences, Wageningen University & Research, Maastricht University and representatives from the textile industry will actively collaborate in the project. Specific approaches have been identified which build on knowledge developed by the knowledge partners in earlier projects. These will now be used for designing sustainable, renewable colourants with the improved quality aspects of light fastness and intensity as required in the textile industry. The selected approaches include refining natural extracts, encapsulation and novel chemical modification of nano-particle surfaces with chromophores.
Cell-based production processes in bioreactors and fermenters need to be carefully monitored due to the complexity of the biological systems and the growth processes of the cells. Critical parameters are identified and monitored over time to guarantee product quality and consistency and to minimize over-processing and batch rejections. Sensors are already available for monitoring parameters such as temperature, glucose, pH, and CO2, but not yet for low-concentration substances like proteins and nucleic acids (DNA). An interesting critical parameter to monitor is host cell DNA (HCD), as it is considered an impurity in the final product (downstream process) and its concentration indicates the cell status (upstream process). The Molecular Biosensing group at the Eindhoven University of Technology and Helia Biomonitoring are developing a sensor for continuous biomarker monitoring, based on Biosensing by Particle Motion. With this consortium, we want to explore whether the sensor is suitable for the continuous measurement of HCD. Therefore, we need to set-up a joint laboratory infrastructure to develop HCD assays. Knowledge of how cells respond to environmental changes and how this is reflected in the DNA concentration profile in the cell medium needs to be explored. This KIEM study will enable us to set the first steps towards continuous HCD sensing from cell culture conditions controlling cell production processes. It eventually generates input for machine learning to be able to automate processes in bioreactors and fermenters e.g. for the production of biopharmaceuticals. The project entails collaboration with new partners and will set a strong basis for subsequent research projects leading to scientific and economic growth, and will also contribute to the human capital agenda.
