Background: Decline in physical activity and functioning is commonly observed in the older population and might be associated with biomarkers such as Advanced Glycation End-products (AGEs). AGEs contribute to age-related decline in the function of cells and tissues in normal aging and have been found …

Background: Accounting for the patients’ perspective on quality of care has become increasingly important in the development of Evidence Based Medicine as well as in governmental policies. In the Netherlands the Consumer Quality (CQ) Index has been developed to measure the quality of care from the patients’ …

Background: In clinical practice, nurses’ attitudes regarding older patients are important in relation to quality of care. The Older People in Acute Care Survey (OPACS) is an instrument measuring hospital nurses attitudes regarding older patients and is validated in Australia and the USA. The OPACS …

From the thesis: This thesis document is the result of research conducted by Peter Straver in culmination of the Master of Informatics in the field of Information Management. The research is supervised by dr. Bas van Gils. Business information, held within information systems, is critical for most organizations. …

BACKGROUND: Ageing is a process that is often accompanied by functional limitation, disabilities and losses. Instead of focusing on these negative events of ageing, there are opportunities in focusing on adaptation mechanisms, like resilience, that are helpful to cope with those adversities. DESIGN: …

Background: The importance of medical education research in Saudi Arabia has been acknowledged increasingly and a lot of concepts used have been derived from the Western world. The question arises, however, whether Western concepts and questionnaires are transferable to societies with different cultures. …

BACKGROUND: Due to the rapidly increasing number of older people worldwide, the prevalence of frailty among older adults is expected to escalate in coming decades. It is crucial to recognize early onset symptoms to initiate specific preventive care. Therefore, early detection of frailty with appropriate …

The CANDECOMP/PARAFAC (CP) model decomposes a three-way array into a prespecified number of R factors and a residual array by minimizing the sum of squares of the latter. It is well known that an optimal solution for CP need not exist. We show that if an optimal CP solution does not exist, then any sequence …

The assumptions of the model for factor analysis do not exclude a class of indeterminate covariances between factors and error variables (Grayson, 2003). The construction of all factors of the model for factor analysis is generalized to incorporate indeterminate factor-error covariances. A necessary …

If the ratio m/p tends to zero, where m is the number of factors m and p the number of observable variables, then the inverse diagonal element of the inverted observable covariance matrix (σ pjj) -1 tends to the corresponding unique variance ψ jj for almost all of these (Guttman, 1956). If the smallest …
