We show how to estimate a Cronbach's alpha reliability coefficient in Stata after running a principal component or factor analysis. Alpha evaluates to what extent items measure the same underlying content when the items are combined into a scale or used for latent variable. Stata allows for testing the reliability …

Background: As the world population ages, the number of people with diminished performance on the Activities of Daily Living (ADL) increases. A reliable and valid measure needs to be developed to determine the effects of interventions focused at increasing self-care abilities. We developed the Performance …

AIM: This paper is a report of the development and testing of the psychometric properties of an instrument to measure the accuracy of nursing documentation in general hospitals. BACKGROUND: Little information is available about the accuracy of nursing documentation. None of the existing instruments that …

In this study we examine how suitability for adoptive parenthood is assessed and displayed in interactions between social workers and prospective adoptive parents. In particular, we have analyzed relationship questions that are put to couples with and without an observation from the social worker. The answers …

The paper is centered on the issue of sustainable development and how cities approach in their urban planning the need to diminish the environmental impact of their economic activities and at the same time create quality of life for their citizens. The focus is specifically on linking economic growth …

The improvement of passive fire protection of storage vessels is a key factor to enhance safety among the LPG distribution chain. A thermal and mechanical model based on finite elements simulations was developed to assess the behaviour of full size tanks used for LPG storage and transportation in fire …

Not only do they offer ink cartridge refills to their consumers, but they also have their own cartridges that can be purchased. Nowadays they are a growing company, but they have not exported yet. …

The central question of this dissertation is what lessons can be learned from Surinam when it comes to the integration of immigrants. Surinam consists of five main population groups and to assess this process of integration this dissertation is structured by the following questions: What is integration …

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 …
