An issue that often confronts the clinician referred an elderly person for neuropsychological assessment is how to interpret the significance of changes in test scores over time. In this report, data useful for estimating the statistical significance of changes on the Rey Auditory Verbal Learning Test (AVLT) are presented. The sample tested comprised 253(More)
Ormerod and Chronicle (1999) reported that optimal solutions to traveling salesperson problems were judged to be aesthetically more pleasing than poorer solutions and that solutions with more convex hull nodes were rated as better figures. To test these conclusions, solution regularity and the number of potential intersections were held constant, whereas(More)
One approach to microbial genotyping is to make use of sets of single-nucleotide polymorphisms (SNPs) in combination with binary markers. Here we report the modification and automation of a SNP-plus-binary-marker-based approach to the genotyping of Staphylococcus aureus and its application to 391 S. aureus isolates from southeast Queensland, Australia. The(More)
OBJECTIVES Scores on neuropsychological tests are often used to detect abnormal changes in cognition in older persons. Accordingly, it is important to have normative data that allow the abnormality of a test score to be determined precisely and accurately. Regression equations that estimate an expected score based on demographic or premorbid factors can be(More)
BACKGROUND The apolipoprotein E (APOE) ε4 genotype is associated with an increased risk of Alzheimer's disease. In community surveys, older adults with this genotype have been found to have lower scores on neuropsychological tests than those who do not. It is possible that this is the consequence of subclinical changes in cognition in those persons who(More)
The assessment of suspected dementia often involves the analysis of change scores from neuropsychological tests administered on two occasions. Frequently, no information is available to allow the significance of a change to be evaluated. Our aim was to prepare data useful for estimating the statistical significance of retest changes for persons older than(More)
In recent years in tertiary institutions in Australia, there has been a large increase of enrolments in Education courses delivered via an online/external mode. This has raised a number of concerns around the nexus of theory and practice and whether pre-service teachers feel ready to teach after completing Education study online. The purpose of this study(More)
