Amsterdam Science Park (ASP) is a pearl in the crown of the Amsterdam knowledge economy, with its high-level research institutes (the Faculty of Science of the University of Amsterdam, several institutes of the NWO, the Dutch national science organisation) and a growing number of knowledge-based companies …

BACKGROUND: Consideration of older adults' quality of life (QoL) is becoming increasingly important in the evaluation, quality improvement and allocation of health and social care services. While numerous definitions and theories of QoL have been proposed, an overall synthesis of the perspective of older …

We introduce two novel methods for multivariate genome-wide-association meta-analysis (GWAMA) of related traits that correct for sample overlap. A broad range of simulation scenarios supports the added value of our multivariate methods relative to univariate GWAMA. We applied the novel methods to life …

Background: Magnetic resonance imaging (MRI) is being used extensively in the search for pathoanatomical factors contributing to low back pain (LBP) such as Modic changes (MC). However, it remains unclear whether clinical findings can identify patients with MC. The purpose of this explorative study was …

This thesis is about volunteer motivation and engagement. The research elaborates on the motivation and engagement of volunteers in the project InduS. Nowadays, a world without volunteers cannot be imagined. They get more and more important in every aspect of social life, for example volunteers are …

Background: In order to internalize the midwifery philosophy of care and to learn how to advocate for physiological childbirth, student midwives in the Netherlands need learning experiences that expose them to physiological childbirth practices. Increased hospital births, wide variation in non-urgent …

Throughout the last three decades, mathematics educators have expressed high expectations of the benefits of using digital technology in mathematics education. In retrospect, however, we admit that this integration has not always been as successful and as smooth as we hoped for. What were the main phases …

Canalization, an intrinsic robustness of development to external (environmental) or internal (genetic) perturbations, was first proposed over half a century ago. However, whether the robustness to environmental stress (environmental canalization [EC]) and to genetic variation (genetic canalization) are …

Background: Osteoarthritis (OA) is the most common rheumatic disease of the musculoskeletal system, with the knee as the most affected joint. The number of people with OA of the knee is likely to increase due to the ageing society and the obesity epidemic. The predominant clinical symptom of knee OA …

Low heart rate variability (HRV) is related to health problems that are known reasons for sick-leave or early retirement. A 1-minute-protocol could allow large scale HRV measurement for screening of health problems and, potentially, sustained employability. Our objectives were to explore the association …
