Use of calcium, folate and vitamin D3-fortified milk for 6 months improves nutritional status but not bone mass or turnover, in a group of Australia aged care

In residential care, inadequate calcium and folate intakes and low serum vitamin D (25(OH)D) concentrations are common. We assessed whether daily provision of calcium, folate, and vitamin D3-fortified milk for 6 months improved nutritional status (serum micronutrients), bone quality (heel ultrasound), bone turnover markers (parathyroid hormone, C-terminal collagen I telopeptide, terminal propeptide of type I procollagen), and/or muscle strength and mobility in a group of Australian aged care residents. One hundred and seven residents completed the study (mean (SD) age: 79.9 (10.1) years; body weight: 68.4 (15.4) kg). The median (inter-quartile range) volume of fortified milk consumed was 160 (149) ml/day. At the end of the study, the median daily vitamin D intake increased to 10.4 (8.7) μg (P < .001), which is 70% of the adequate intake (15 μg); and calcium density (mg/MJ) was higher over the study period compared with baseline (161 ± 5 mg/MJ vs. 142 ± 4 mg/MJ, P < .001). Serum 25(OH)D concentrations increased by 23 ± 2 nmol/L (83 (107)%, P < .001), yet remained in the insufficient range (mean 45 ± 2 nmol/L). Consumption of greater than the median intake of milk (160 ml/day) (n = 54, 50%) increased serum 25(OH)D levels into the adequate range (53 ± 2 nmol/L) and reduced serum parathyroid hormone by 24% (P = .045). There was no effect on bone quality, bone turnover markers, muscle strength, or mobility. Consumption of fortified milk increased dietary vitamin D intake and raised serum 25(OH)D concentrations, but not to the level thought to reduce fracture risk. If calcium-fortified milk also was used in cooking and milk drinks, this approach could allow residents to achieve a dietary calcium intake close to recommended levels. A vitamin D supplement would be recommended to ensure adequate vitamin D status for all residents.

A tangled tale of two teal : population history of the grey Anas gracilis and chestnut teal A. castanea of Australia

Two Australian species of teal (Anseriformes: Anatidae: Anas), the grey teal Anas gracilis and the chestnut teal A. castanea, are remarkable for the zero or near-zero divergence recorded between them in earlier surveys of mitochondrial DNA (mtDNA) diversity. We confirmed this result through wider geographical and population sampling as well as nucleotide sampling in the more rapidly evolving mtDNA control region. Any data set where two species share polymorphism as is the case here can be explained by a model of gene flow through hybridization on one hand or by incomplete lineage sorting on the other hand. Ideally, analysis of such shared polymorphism would simultaneously estimate the likelihood of both phenomena. To do this, we used the underlying principle of the IMa package to explore ramifications to understanding population histories of A. gracilis and A. castanea. We cannot reject that hybridization occurs between the two species but an equally or more plausible finding for their nearly zero divergence is incomplete sorting following very recent divergence between the two, probably in the mid-late Pleistocene. Our data add to studies that explore intermediate stages in the evolution of reciprocal monophyly and paraphyletic or polyphyletic relationships in mtDNA diversity among widespread Australian birds.

Practitioner perceptions of sustainability in the Building Code of Australia

Buildings have a significant impact on environmental quality, resource use, human health and productivity. One definition of sustainable building is that which meets current building needs and reduces impacts on future generations by integrating building materials and methods that promote environmental quality, economic vitality, and social benefit’ (City of Seattle, 2006). In response to a changing view of
sustainability the Building Code of Australia (BCA) adopted energy measures in 2005 to residential buildings and, in 2006, to Class 1 – 9 buildings. In many respects the measures represented a watershed for the Australian Building Regulations which had not included sustainability within the BCA. The goals of the BCA are to enable the achievement and maintenance of acceptable standards of structural sufficiency, safety (including safety from fire), health and amenity for the benefit of the community now and in the future (ABCB, 2004a). As with any change some Building Surveyors and construction practitioners viewed these measures with apprehension. How would the measures be assessed? Furthermore, was the BCA the appropriate place for these measures and was this a broadening of the scope of the building regulations beyond
its traditional remit of health and life safety in buildings? This research used a questionnaire survey the canvass the views and perceptions of Building Surveyors and Architects with regards to sustainability and the BCA in 2006.

A panel data analysis of the determinants of oil consumption : the case of Australia

The goal of this paper is to examine the determinants of oil consumption for a panel consisting of six Australian States and one territory, namely Queensland, New South Wales, Victoria, Tasmania, South Australia, Western Australia, and the Northern territory, for the period 1985–2006. We find that oil consumption, oil prices and income are panel cointegrated. We estimate long-run elasticities and find that oil prices have had a statistically insignificant impact on oil consumption, while income has had a statistically significant positive effect on oil consumption.

Hail to the chief! Leadership and structural change in the level of consensus on the High Court of Australia

This article identifies structural breaks in dissenting and single opinions on the High Court of Australia and uses a recent method proposed by Caporale and Grier (2002) to examine the effect of leadership on variations in the dissent rate between 1904 and 2001. Although there has been much speculation about the effectiveness of different Chief Justices in obtaining consensus on the Court, to this point most of the evidence has been anecdotal. Our main findings are that the structural breaks that we identify coincide with major turning points in the leadership of the Court and that leadership has been important in explaining variations in the proportion of dissenting opinions on the Court.

Adult learning experience : learning in mixed-mode forms of professional development in the Northern Territory of Australia

This qualitative research is an examination of the experience of learning within a mixed-mode teachers' professional development program. It examines how learning is affected by 'location' - geographic, institutional and personal, and how teaching may take location into account. Approaches to study, influences on learning and transformational learning are explored.

An examination of Australia's insider trading laws

Considers that the effective regulation of insider trading is desirable in order to maintain investor confidence in Australia's share markets. Although the current laws and the use of continuous disclosure provide a workable foundation, the thesis further considers the ways in which insider trading may be more effectively regulated and prosecuted in Australia.

Business valuation practice issues under Family Court of Australia proceedings

The study investigated the valuation of businesses valued for property settlements in the Family Court of Australia and related issues. The findings have important implications for the Family Court of Australia, the legal profession and the accounting profession in highlighting deficiencies in valuation practice at various stages of the settlement process.

Inflation and economic growth : a comparative analysis of Australia and the Philippines

Investigates the effects of inflation on economic growth in Australia and the Philippines using time-series data for each country. Uses time-series quarterly data sets covering the period 1970-1995 for Australia and 1950-1994 for the Philippines. A production function approach is used. Inflation was found to have a negative and statistically significant but differing impact on growth in both countries.

Cenozoic echinoids of Australia

The project involved a series of palaeontological investigations into the taxonomic classification of fossil echinoids from the Cenozoic Era of Australia. This included evolutionary reconstructions and aspects of palaeobiology. The palaeobiogeographical distribution of the Australian fossil echinoids revealed a changing pattern which partly explains the origin of the modern fauna.
