Weight gained in two years by a population of mid-aged women: how much is too much?

Objective: To establish the prevalence of weight change in mid-aged women over a 2-year period, and to assess the relationship between weight change and physical and mental well-being (SF36) in order to begin debate about the need for quantified standards of weight gain. Design: Prospective study of weight change and well-being over a 2-year period among mid-aged women participating in a large national survey. Subjects: Seven thousand two hundred and seventy women without surgical menopause aged between 45 and 50 years (termed mid-aged), enrolled in the Australian Longitudinal Study on Women's Health. Measurements: Weight change (self-reported weight at two time points) and physical and mental well-being (SF-36) explored using linear regression, while adjusting for potential confounders. Results: Only half the women maintained their weight within 2.25 kg, and one-third gained more than this amount in a 2-year period. While weight gain (>= 2.25 kg) was negatively associated with physical well-being, both weight loss and weight gain were associated with poorer mental well-being. Conclusion: This is the first prospective study using a large, population-based cohort to demonstrate that small changes in weight are associated with changes in well-being in mid-aged Australian women. It provides further evidence of the need for public health messages to specify the actual amount that constitutes weight gain, but further research is needed to establish these standards for the entire population.

Thomas Parmeter: Poetaster and Rhymist

The life of Dr. Thomas Parmeter MD was one of astonishing complexity. Convicted of bigamy in London, he arrived in Sydney on 16 January 1816 and almost immediately resumed his medical practice. In England he had engaged in several literary activities and these too he soon resumed in New South Wales, contributing to contemporary newspapers. A riding accident in 1820 and a stroke in 1825 restricted his ability to practise medicine and so he turned to writing and farming for an income. Neither activity was a financial success and he died in poverty. Herein are collected together his poems, epigrams, aphorisms and quotations from poets and other writers. His contribution to the cultural life of Sydney, though not fully documented, was very likely significant.

Thermal effects in the evolution of initially layered mantle material

A simplified model for anisotropic mantle convection based on a novel class of rheologies, originally developed for folding instabilities in multilayered rock (MUHLHAUS et al., 2002), is extended ¨ through the introduction of a thermal anisotropy dependent on the local layering. To examine the effect of the thermal anisotropy on the evolution of mantle material, a parallel implementation of this model was undertaken using the Escript modelling toolkit and the Finley finite-element computational kernel (DAVIES et al., 2004). For the cases studied, there appears too little if any effect. For comparative purposes, the effects of anisotropic shear viscosity and the introduced thermal anisotropy are also presented. These results contribute to the characterization of viscous anisotropic mantle convection subject to variation in thermal conductivities and shear viscosities.

Vic Slater during the Youth Campaign against Conscription, Brisbane, Australia

Vic Slater and police during the Youth Campaign against Conscription, Brisbane, Australia in 1965. Victor Charles Slater (now retired) was born in Queensland in March 1944 the only child of Jim and Joyce Slater, card carrying members of the Communist Party of Australia. Vic's mother, Joyce, joined up in Great Britain. Vic too joined the party in 1962 after a stint as president of the Eureka Youth League. He stayed with the more broad left CPA when it split from the hardline Stalinists after the Soviet invasion of Czechoslovakia in 1968. Vic joined the Waterside Workers' Federation before his 21st birthday in January 1965, one of 300 casual workers recruited to the Port of Brisbane that year. On the wharves he soon earned the nickname 'the Professor' arriving on the job each day bespectacled and carrying a briefcase heavy with reading matter on world politics and economics - a walking encyclopaedia of information.

'Living together on one's own': Cohousing for older people - an example from Denmark and The Netherlands

‘Living together on one’s own’ is the seemingly contradictory expression of the National Association of Housing Communities for Elderly People (LVGO) in The Netherlands which in fact captures the essence of cohousing. Cohousing is a novel kind of neighbourhood, housing a novel form of intentional community, which began to take shape in Denmark in the early to mid-1960s and, independently, in The Netherlands a few years later. The inventors of cohousing wanted to live in a much more communal or community-oriented neighbourhood than was usual, but they wanted to do so without sacrificing the privacy of individual families or households and their dwellings. Could they have their cake and eat it too? It would seem so. What is cohousing for older people (op-cohousing)? Op-cohousing is essentially no different, except for the differences in outlook or expectations, experience, interests and abilities that a particular, exclusively older, group of people have brought to this housing type. I discuss and analyse several communities in both countries.
