Trends in co-authorship in the Australian Group of Eight law reviews

This paper examines trends in co-authorship in the Group of Eight (Go8) law reviews over the period 1975 to 2010. Several conclusions emerge. First, co-authorship occurs less in legal scholarship than in other disciplines. Second, co-authorship in Australian legal scholarship is less than in legal scholarship in the United States. Third, in terms of gender differences, males collaborate more than females. Fourth, academics at the leading law schools provide a disproportionate number of co-authored articles in the Go8 law reviews. Fifth, there is a positive correlation between co-authorship and publishing in the top Australian law journals. Between a quarter and a third of those who co-authored three or more articles in the Go8 law reviews were also those who published the most in the top Australian law journals over the period 1990–2010.

Direct comparison of eight national FRAX® tools for fracture prediction and treatment qualification in Canadian women

The authors compared the calibration of FRAX tools from Canada, the US (white), UK, Sweden, France, Australia, New Zealand, and China when used to assess fracture risk in 36,730 Canadian women. Their data underscores the importance of applying country-specific FRAX tools that are based upon high-quality national fracture epidemiology.

A new class of eight-membered Sn2P2O4 heterocycles. Crystal structure and electrolytic dissociation in solution of cyclo-[R2Sn(OPPh2O)2SnR2](O3SCF3)2(R=Me, t-Bu)

The syntheses of cyclo-[R₂Sn(OPPh₂O)₂SnR₂](O₃SCF₃)₂ (R = Me (1), t-Bu (2)) by the consecutive reaction of R₂SnO (R = Me, t-Bu) with triflic acid and diphenylphosphinic acid are presented. In the solid state, 1 and 2 were investigated by ¹¹⁹Sn MAS and ³¹P MAS NMR spectroscopy as well as X-ray crystallography and appear to exist as ion pairs of cyclo-[R₂Sn(OPPh₂O)₂SnR₂]²⁺ dications and triflate anions. In solution, 1 and 2 are involved in extensive equilibria processes featuring cationic diorganotin(IV) species with Sn-O-P linkages, as evidenced by ¹¹⁹Sn and ³¹P NMR spectroscopy, electrospray mass spectrometry, and conductivity measurements.

Comparison of the flexibility of eight-membered tetrasiloxane and stannasiloxane rings: a crystallographic and computational study

The syntheses and crystal structures of the eight-membered cyclo-stannasiloxanes cyclo-[t-Bu(OH)Si(OSnt-Bu₂O)₂Si(OH)t-Bu] (1) and cyclo-{t-Bu₂Si[OSn(CH₂SiMe₃)₂O]₂Sit-Bu₂} (2) as well as the synthesis of the six-membered cyclo-stannasiloxane cyclo-{t-Bu₂Si[OSn(CH₂SiMe₃)₂]₂O} (3) are reported. Compound 1 crystallizes as its trans isomer, but the cis isomer dominates in solution. In agreement with the experimentally obtained results, ab initio and DFT calculations on the model compounds cyclo-(H₂SiO)₄ (4), cyclo-[H₂Si(OSnH₂)OSiH₂] (5), cyclo-O(H₂SiOSnH₂)₂O (6), and cyclo-[H₂Si(OSiH₂)OSnH₂] (7) indicate that the energetic preference to adopt puckered structures increases and the ring flexibility decreases with an increasing number of tin atoms in the ring. The rich diversity of puckered conformations is attributed to the steric demand of the different organic substituents.

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.

Modelling money demand for a panel of eight transitional economies

In this article, we estimate money demand functions for a panel of eight transitional economies, using quarterly data for the period 1995:01 1995 to 2005:03. We find that real M1 and real M2 and their determinants, namely real income and short-term domestic interest rate, are cointegrated, both for individual countries as well as for the panel. Long-run elasticities suggest that consistent with theory, real income positively and nominal interest rate negatively impact real money demand. Our test for panel Granger causality suggests short-run bidirectional causality between M1 and M2 and their determinants. Finally, our tests for stability of the money demand functions reveal more cases of unstable money demand functions when M2 is used as a proxy for money demand.

Sustainability in online communities of practice : the case study of a group of Secondary School Educators in Victoria

This paper reports on Information Technology (IT) secondary school educators in Victoria and their involvement in an online community of practice. It examined the social effects of the online mailing list technology on their participation and factors that influenced their collaboration with other colleagues. In mapping these elements, the motivations of educators and the effects on online communities of practice can be distilled and then used to build and sustain other architectures of participation. It was found that mailing list subscribers seem to trade a currency of support, thoughts, ideas and answers, which helped them in their day-to-day teaching. Online communities of practice provide a convenient way to keep up professional networks while continuing to stay abreast with subject specific knowledge and skills. The findings of this case study may be generalised to other educational mailing lists to guide designers and managers and inspire educators to join and ultimately benefit from these text based online environments.

Survey of a group of nineteenth and early twentieth century British millionaires : the influence of this wealth on their descendants

This study selected British wealth holders who died between 1858 and 1914 and registered probate values of over 1 million pounds. Their descendants were traced using an array of sources. These descendants generally consisted af a group of wealthy individuals in the upper few percent of wealth holders in the British community as indicated by their probate valuations. Generally the male descendants were wealthier, received a better education, and dominated in commerce and business activities.
