2012, Article / Letter to editor (Wetenschappelijk Tijdschrift voor Ergotherapie, vol. 5, iss. 4, (2012), pp. 24-38)Volgens internationale schattingen is de prevalentie van de diagnose Developmental Coordination Disorder (DCD) minstens 6% voor kinderen in de leeftijd van 5 tot 11 jaar (1). De American Psychiatric Association (APA) heeft DCD gedefinieerd als “The essential feature of DCD is a marked impairment in the development of motor coordination (…) that significantly interferes with academic achievement or activities of daily living” (1). Vrij vertaald naar het Nederlands betekent dit: ‘een aantoonbare verstoring in de ontwikkeling van de motorische coördinatie (…) dat significant interfereert met de schoolse prestaties of met algemene dagelijkse activiteiten’. Vanwege het effect van DCD op het dagelijks leven van kinderen en hun familie (2) is het noodzakelijk dat we interventies toepassen met als doel het dagelijks leven te verbeteren (3).
2015, Article / Letter to editor (Ultrasound in Medicine and Biology, vol. 41, iss. 6, (2015), pp. 1784-1793)Described here is an ultrasound technique used to study tongue movements, particularly lateral tongue movements, during mastication. A method to analyze spatial and temporal tongue movements was developed, and the feasibility of using this method was evaluated. Biplane ultrasound images of tongue movements of four adults without oral motor disability and two adults with oral motor disability as a result of cerebral palsy, were acquired. Tongue movements were analyzed in the coronal and sagittal planes using B-mode and M-mode ultrasonography. Inter-rater and intra-rater agreement for manual tracing of tongue contours was good (ICC = 0.81 and 0.84, respectively). There were significant differences between the two adult groups in movement frequency in the horizontal direction in both coronal and sagittal planes. In the coronal plane, differences in movement frequency and range of vertical movement were detected. Data obtained from sagittal images, with the exception of vertical frequency, indicated no differences between the groups. The protocol developed in this study (using B-mode and M-mode) proved to be valid and reliable. By using this protocol with individuals with and without oral motor disability, we were able to illustrate the clinical application of our protocol to evaluation of differences in tongue movements during mastication.
2022, Article / Letter to editor (Population Health Management, vol. 25, iss. 2, (2022), pp. 172-177)Comprehensive social risk screening has become standard practice in primary care. Evidence is lacking, however, on whether and how interventions provided for positive screens are being utilized. This study aimed to create a standardized follow-up process to evaluate caregiver perspective and usage of community resources provided during well-child visits. Follow-up calls were made to families with positive screens for food insecurity (FI) and/or utility insecurity (UI) (nn=n347). Phone interviews assessed resource usage, effectiveness, influence on stress level, and current insecurity status. Caregiver responses regarding barriers to resource usage were inductively analyzed and developed into major themes. The sample included 228 (65.7%) families with positive screens for FI and 166 (47.8%) families screening positive for UI. Of those who completed interviews (nn=n108), 77 (71.3%) caregivers recalled being provided resources during their child's visit with only 33 (42.9%) reporting use of those resources. Twelve (36.4%) of those caregivers who used the resources confirmed that their insecurity was still a concern. Five major themes for barriers to resource usage emerged: (1) improved situation, (2) perception, (3) access barriers, (4) conflicting priorities, and (5) too busy/overwhelmed. The majority of caregivers (95.7% of asked) noted that their insecurity caused increased stress with 70.5% acknowledging decreased stress levels after discussion with a provider. Integrating caregiver input through a standardized follow-up protocol into provided interventions for screened social risks can improve not only the quality and effectiveness of provided resources, but also provide insight into the impact of those interventions on insecurity from the caregiver perspective.
2012, Article in monograph or in proceedings (SRHE)Due to the changing role and context of (new) universities, roles of lecturers are renewed and diversified. In this study, weekly written narratives from lecturers on their development in novel researcher roles at new universities are collected over time and analyzed correspondingly. Understanding how individuals accomplish role transition is important to the health of individuals and organizations alike. The method provided examples of configurations derived from within-case analyses and illustrates lecturers’ work and learning activities, kinds of support and affirmation succeeded each other which resulted in changes of intermediate outcomes during lecturers’ development trajectories. In studying lecturers’ role transition, outcomes such as role learning, identity and competence development, and strides in building up research capacity are taken into account. The analysis of the narratives provides meaningful insights into the inspiring, challenging, and ambiguous, erratic nature of the transition into researcher roles at new universities, as experienced by the lecturers.

2018, Article in monograph or in proceedings (FEDERATED CONFERENCE ON COMPUTER SCIENCE AND INFORMATION SYSTEMS / In FedCSIS (ed.), Project: Hospital’s IT infrastructure capability and digital capabilities, pp. 87-94)This study links business requirements and adaptability of existing software systems. Organizations expect flexibility of IT with regard to business requirements. We hypothesize that the flexibility of business requirements is difficult in IT systems, because of software dependencies in the way domain knowledge is implemented. In this paper, we, therefore, explore how Business requirements have been implemented in the source code of three open source healthcare systems. Outcomes suggest that a tight interdependency of business terminology and functionality in source code hides business requirements from view and thereby hinders IT flexibility on higher levels.

2010, Article / Letter to editor (Learning and Instruction, vol. 20, iss. 4, (2010), pp. 265-269)Peer assessment is an educational arrangement where students judge a peers performance quantitatively and/or qualitatively and which stimulates students to reflect, discuss and collaborate. However, empirical evidence for peer assessment effects on learning is scarce, mostly based on student self-reports or involving comparison of peers and teachers ratings or anecdotal evidence from case studies. Systematic investigation of learning effects necessitates methodological, functional, and conceptual development in peer assessment research. This implies sound (quasi-)experimental studies, the definition of specific peer assessment mechanisms, and affiliations with other research domains. The articles in this special issue address these three needs and offer new directions for research.
2012, Article / Letter to editor (Acta Horticulturae, iss. 952, (2012), pp. 531)A greenhouse with Fresnel lenses in the south facing roof and a receiver for concentrated Photovoltaics with water cooling (CPVT system) will result in electrical and thermal energy output from the solar energy excess entering a greenhouse. The PV system converts about half of the direct radiation into heat and electricity. During periods with direct radiation this will significantly reduce the heat load on the greenhouse. For an optimal performance the roof elements must be asymmetric with a steep inclination at the north side (the exact angle of course depends on the latitude of the building site). The Fresnel lens structure is best oriented in upwards direction. In the current design, two lenses are placed in the inner space of a double glass. This prevents pollution and condensation on the lenses. By the upward facing of the lens structure, the focus quality is preserved over a much broader range of angles of incidence compared to a lens with downward facing structures. Each PMMA lens with a size of 1.20×1.52 m is composed of 12 ‘tiles’ for easy production. The focal distance of the lens is 1,875 m and the geometrical concentration factor is 50×. This means that in most cases the focus line is thinner than 3 cm. The performance of the lens with respect to the shape of the focal area and the position of the focal line has been analyzed with ray tracing techniques. From this analyses and by the development of a smart tracking system only two motors can bring the receivers in the required positions. One motor controls the distance between lens and receiver and the other controls the translocation of the receivers parallel to the lens. The second conclusion was that the positions of the focal line are within the bounds of the greenhouse construction for almost the whole year. Only in winter, in the early morning and at the end of the day, the focal line will be unreachable. The 480 m2 greenhouse, with the LCPVT system based on Static Fresnel lenses and a 40 m CPVT-module and a 200 m CT-module, is designed by Bode Project Engineering and constructed by Technokas in Bleiswijk the Netherlands.
2011, Article / Letter to editor (Proteome Science, vol. 9, iss. 13, (2011))Suitable biomarkers associated with the development of delirium are still not known. Urinary proteomics has successfully been applied to identify novel biomarkers associated with various disease states, but its value has not been investigated in delirium patients. In a prospective explorative study hyperactive delirium patients after cardiac surgery were included for urinary proteomic analyses. Delirium patients were matched with non-delirium patients after cardiac surgery on age, gender, severity of illness score, LOS-ICU, Euro-score, C-reactive protein, renal function and aorta clamping time. Urine was collected within 24 hours after the onset of delirium. Matrix-assisted laser desorption/ionisation-time of flight mass spectrometry (MALDI-TOF MS) was applied to detect differences in the urinary proteome associated with delirium in these ICU patients. We included 10 hyperactive delirium and 10 meticulously matched non-delirium post-cardiac surgery patients. No relevant differences in the urinary excretion of proteins could be observed.

2004, Article / Letter to editor (Disability and Rehabilitation, vol. 26, iss. 17, (2004), pp. 1060-1066)PURPOSE: There are many models describing the responses of the human organism to work. However, the description of the effects on a personal level is rather limited. For this purpose the authors propose to use the concepts and the terminology of the ICF - the International Classification of Functioning, Disability and Health. METHOD: This article starts with a description of a model from occupational medicine, the Van Dijk model. Subsequently an overview of the health state of employees is presented, including the external and personal factors that may influence participation in work. RESULTS: The schematic representation of the external and personal factors presented in this article is an expansion of the ICF-scheme. The scheme can be useful to describe problems of persons related to the working situation, and to identify the points of application of care for different professionals. Although the scheme does not have the intention to be complete, it might be useful in the development, execution and evaluation of programmes designed to prevent absenteeism in general or in specific groups, and to stimulate the return of people with absence due to illness. It is shown that the items of the Van Dijk model can be described using specific terms of the ICF. CONCLUSION: With the elaboration of the ICF scheme and the model of Van Dijk, expanded with ICF terms, the gap between the terminology used by professionals in health care, and the terminology used by professionals in occupational medicine is partly filled.

2013, Article in monograph or in proceedings (Paper presented at the 7th International Conference on Research and Practical Issues of Enterprise Information Systems CONFENIS)IT architects in practice have a difficult task in extending and adapting enterprise information systems. Mastering complexity is a priority. This is still more art than craftsmanship in spite of many years of academic research in IT architecture. We will explore by a series of case studies how to support IT architects in practice, with their work of improving the consistency and completeness of emerging architectures. In this process, IT architects should be capable of discussing conflicting, incomplete, highly abstract, or overly detailed requirements with stakeholders and developers, while keeping an overview of all priorities and constraints. In this research paper, we first discuss the research strategy, Design research combined with case study research, to address this question. Next, we discuss Ampersand and its tool, a rule-based modeling language, and an engine developed in high-level IT consultancy. Ampersand seems promising for flexible modeling of IT architecture, and its rule engine can help IT architects manage consistency between requirements and IT solutions. An empirical exploration in developing the IT architecture for a new specialized child oncology hospital is used to check the premises of our research and the usefulness of Ampersand in this context. The conclusions of this exploration have led to hypotheses for testing in further research. The hypotheses concern applying the Ampersand approach to effectively support IT architects’ work.
2022, Article / Letter to editor (European Journal of Sport Science, (2022), pp. 1-10)HighlightsRunning with a musical rhythm that is higher than the preferred cadence leads to an increased running cadence, without increasing heartrate and running speed.This cadence remains elevated for at least three to five weeks after the music intervention period.All individuals showed a practically relevant increase in cadence during and after the intervention.
2010, Article / Letter to editor (BMC Public Health, vol. 2010, iss. 10, (2010), pp. 353)Employees with a chronic disease often encounter problems at work because of their chronic disease. The current paper describes the development of a self-management programme based on the Chronic Disease Self-Management programme (CDSMP) of Stanford University to help employees with a chronic somatic disease cope with these problems at work. The objective of this article is to present the systematic development and content of this programme. The method of intervention mapping (Bartholomew 2006) was used to tailor the original CDSMP for employees with a chronic somatic disease. This paper describes the process of adjusting the CDSMP for this target group. A needs assessment has been carried out by a literature review and qualitative focus groups with employees with a chronic disease and involved health professionals. On the basis of the needs assessment, the relevant determinants of self-management behaviour at work have been identified for the target population and the objectives of the training have been formulated. Furthermore, techniques have been chosen to influence self-management and the determinants of behaviour and a programme plan has been developed.
2021, Article / Letter to editor (BMC Health Services Research, vol. 21, iss. 1, (2021))BackgroundMalnutrition, sarcopenia and cachexia are clinical wasting syndromes characterised by muscle loss. Systematic monitoring by body composition assessment (BCA) is recommended for the diagnosis, treatment and monitoring of the syndrome(s). This study investigated practices, competency, and attitudes of Australian dietitians regarding BCA, to inform a local implementation process.MethodsApplying the Action cycle in the Knowledge to Action framework, surveys were distributed to the 26 dietitians of an 800-bed tertiary hospital. The survey assessed barriers and enablers to performing routine BCA in clinical care. Results were categorised using the Theoretical Domains Framework (TDF) and suitable interventions mapped using the Behaviour Change Wheel.ResultsTwenty-two dietitians (84.6%) completed the survey. Barriers to BCA were identified in all TDF domains, particularly in Knowledge, Skills, Social/professional role and identity, Beliefs about capabilities, and Environmental context and resources. Enablers existed in domains of: Skills; Beliefs about consequences; Goals; Environmental context and resources; Social influences; Intentions; Optimism; Reinforcement.ConclusionsThis study showed that hospital dietitians experience individual, team, and organisational barriers to adopt BCAs in clinical practice. We were able to formulate targeted implementation strategies to overcome these barriers to assist BCA adoption into routine practice.
2012, Article / Letter to editor (Progress in Photovoltaics: Research and Applications, (2012))In this study, we present a new light absorption enhancement method for p-i-n thin film silicon solar cells using pyramidal surface structures, larger than the wavelength of visible light. Calculations show a maximum possible current enhancement of 45% compared with cells on a flat substrate. We deposited amorphous silicon (a-Si) thin film solar cells directly onto periodically pyramidal-structured polycarbonate (PC) substrates, which show a significant increase (30%) in short-circuit current over reference cells deposited on flat glass substrates. The current of the cells on our pyramidal structures on PC is only slightly lower than that of cells on Asahi U-type TCO glass (Asahi Glass Co., Tokyo, Japan), but suffer from a somewhat lower open circuit voltage and fill factor. Because the used substrates have a locally flat surface area due to the fabrication process, we believe that the current enhancement in the cells on structured PC can be increased using larger or more closely spaced pyramids, which can have a smaller flat surface area.
2012, Article in monograph or in proceedings (The Web and Beyond 2012)The internet is becoming a tightly interwoven part of our everyday lives. There is a growing market for web services which augment the daily life of users trough products with an internet connection. We call these real world extensions of the web embedded media. In the last couple of years we explored embedded media design through student projects with real world clients. We learned that the UX difficulty of embedded media design is to mix, enforce and augment existing user experiences. We’ve tried to capture this challenge in the intuitive notion of experience blend. In this paper we use examples from our project work to introduce this notion of experience blend.
2009, Article / Letter to editor (Scandinavian Journal of Occupational Therapy, vol. 16, iss. 4, (2009), pp. 205-215)The objective of this study was to produce a valid Danish translation of the Dutch "Occupational therapy guideline for assessment and treatment of apraxia in CVA clients"; to investigate the inter-rater reliability of the assessment instrument in terms of ADL observations; and to determine the content validity of the translation. The inter-rater reliability was investigated using video observations and multiple raters, who also judged the content validity quantitatively. For the scores of the patient's occupational performance the study found moderate to good inter-rater reliability for three of four variables and poor to fair inter-rater reliability for one variable, indicated by intra-class correlation coefficient and Kappa statistic. For the conclusion variables the results demonstrated fair inter-rater reliability for five of six variables and poor inter-rater reliability for one variable, also indicated by Kappa statistic. The content validity was judged valid for 100 and invalid for 28 of the guideline's defined elements. The conclusion, taking the complexity of the ADL observations and the study design into consideration, is that the Danish version can serve as a guideline within Danish occupational therapy practice. However, a translational recheck, further psychometric testing, and a minimum two-day training course is recommended before implementation in practice.
2010, Article / Letter to editor (Intensive Care Medicine, vol. 36, iss. suppl. 2, (2010), pp. s341)Delirium is a frequent disorder in the ICU associated with poor outcome. Several organizations, including the SCCM and the APA, therefore recommend standard screening for delirium to improve early diagnosis and treatment. The CAM-ICU is the most frequently used delirium detection tool in the Netherlands. Numerous studies to validate the CAM-ICU always yielded excellent sensitivity and specificity, but were all performed by a limited number of research nurses.
