Teaching and Learning Science through Multiple Representations: Intuitions and Executive Functions.

Reasoning about visual representations in science requires the ability to control one's attention, inhibit attention to irrelevant or incorrect information, and hold information in mind while manipulating it actively-all aspects of the limited-capacity cognitive system described as humans' executive functions. This article describes pedagogical intuitions on best practices for how to sequence visual representations among pre-service teachers, adult undergraduates, and middle school children, with learning also tested in the middle school sample. Interestingly, at all ages, most people reported beliefs about teaching others that were different from beliefs about how they would learn.

Functional haplotypes in the PTGDR gene fail to associate with asthma in two Australian populations.

Background And Objective: Haplotypes in the promoter region of the prostanoid DP receptor (PTGDR) gene have been shown to functionally influence gene transcription and to be associated with asthma in two previous case-control studies in Caucasians. This study tested the association of PTGDR haplotypes with asthma phenotypes in two large Caucasian-Australian populations. These results were incorporated in a meta-analysis with previously published data to determine the overall role for these haplotypes in the risk of asthma.

Readiness to shop for low-fat foods: a population study.

Background: Stages of change are related to dietary fat consumption. Few studies have examined stage occupation within the context of purchasing low-fat foods.

Objective: To determine the stage-prevalence of individuals for purchasing low-fat foods; identify the frequency of misclassification into action and maintenance (A/M) stages for purchasing for low-fat foods; and explain the demographic and cognitive-variable differences between pseudo (or false positive) A/M and true A/M individuals.

Impact of an anemia clinic on emergency room visits and hospitalizations in patients with anemia of CKD pre-dialysis.

Aim: There is limited data regarding the impact on hospital resource use of a dedicated, nurse-managed anemia clinic in patients with pre-end stage chronic kidney disease.

Methods: A retrospective cohort study was conducted comparing patients with pre-end stage anemia of chronic kidney disease enrolled in an algorithmic anemia clinic (N = 27, treatment group) with un-enrolled patients with chronic kidney disease (N = 22, control group). The treatment group received algorithmic treatment with recombinant human erythropoietin and intravenous iron sucrose, while controls received usual care.

Age and sex differences in malignant mesothelioma after residential exposure to blue asbestos (crocidolite).

Background: Blue asbestos was mined and milled at Wittenoom, Western Australia, from 1943 until 1966. Various public records were used to establish a cohort of residents of the nearby township. Mine tailings were distributed throughout the town.

The Western Australian Register of Childhood Multiples: effects of questionnaire design and follow-up protocol on response rates and representativeness.

Twin registers have been established worldwide to study the roles of genes and the environment in health and behaviour. While questionnaire surveys are thought to be the most cost-effective way of collecting large amounts of data, low response rates can result in response bias. Many different strategies have been proposed to maximise response rates.

Population based ascertainment of twins and their siblings, born in Western Australia 1980 to 1992, through the construction and validation of a maternally linked database of siblings.

This paper describes the creation of a unique maternal identifier for use in the investigation of perinatal, postneonatal and child outcomes in relation to maternal characteristics. All Midwives' records of Western Australian (WA) births were routinely linked to registrations of births and deaths for infants born from 1980 to 1992 inclusive, then linked to WA hospital discharge data and to registries of birth defects and cerebral palsy to create a longitudinal health record for each infant. However, since each birth to a woman was recorded as a separate event, there was no way to identify siblings.
