Objective: To examine the prevalence of low serum folate and vitamin B12, in association with elevated serum homocysteine, in a representative sample of older Australians. Methods: During 1997-2000, 3,508 persons aged 50+ years were examined in a population-based cohort study conducted in two postcodes, west of Sydney, Australia. Of these, 2,901 participants (82.7%) provided fasting blood for estimates of serum folate, vitamin B12 and total homocysteine. Results: Low serum B12 (<185 pmol>/L) was found in 22.9% of participants and low serum folate (<6.8 nmol/L) in 2.3% of participants. Among those people with very low serum vitamin B12 (<125 pmol/L) and low serum folate, 51% had elevated homocysteine. Conclusions: Low serum levels of vitamin B12 and elevated serum homocysteine are relatively frequent in older Australians. Implications: Appropriate public health action should be considered to reduce the prevalence of low serum vitamin B12 and elevated homocysteine in older Australians.
Do We Encourage Health Or Illness? A Survey Of Exercise Rehabilitation Practices For Patients In Australian Renal Units, Y. White, B. Grenyer
Do We Encourage Health Or Illness? A Survey Of Exercise Rehabilitation Practices For Patients In Australian Renal Units, Y. White, B. Grenyer

Background: People with end stage renal disease (ESRD) have been reported as having low levels of physical activity. Sedentary behaviours increase illness risks which may lead to burdens on the public health system which include costs of medical care. Research has established that exercise is reported to improve general health and wellbeing. Benefits include better aerobic tolerance, maintenance and improvement in physical function and capacity, and improvement in self-concept and well-being. These same improvements also occur in an exercising ESRD population, even though the improvements might be of less magnitude. Renal unit staff can have a major impact on patients …

Sources Of Price Discovery In The Australian Dollar Currency Market, Alex Frino, Elvis Jarnecic, Andrew S. Tan, Maxwell Stevenson
Sources Of Price Discovery In The Australian Dollar Currency Market, Alex Frino, Elvis Jarnecic, Andrew S. Tan, Maxwell Stevenson

This paper examines the source of price discovery in the Australian Dollar currency market. The time-varying relationship between changes in quotes posted by cash market dealers and changes in currency futures quotes is estimated. The cash market quotations identifY the eleven dealers posting the quotes, as well as geographical location of the dealers (Australia or overseas). Reported results show that price discovery originates in the cash market in any trading period. Amongst CUlTency dealers, the results imply that local desks are price leaders during Australian trading hours. Though some foreign desks do contribute to price discovery during the European and …
Macroeconomic Risk Factors In Australian Commercial Real Estate, Listed Property Trust And Property Sector Stock Returns, Tracey West, Andrew C. Worthington
Macroeconomic Risk Factors In Australian Commercial Real Estate, Listed Property Trust And Property Sector Stock Returns, Tracey West, Andrew C. Worthington
Faculty of Commerce - Papers (Archive)
This paper employs a Generalised Autoregressive Conditional Heteroskedasticity in Mean (GARCH-M) model to consider the effect of macroeconomic factors on Australian property returns over the period 1985 to 2002. Three direct (office, retail and industrial property) and two indirect (listed property trust and property stock) returns are included in the analysis, along with market returns, short, medium and long-term interest rates, expected and unexpected inflation, construction activity and industrial employment and production. In general, the macroeconomic factors examined are found to be significant risk factors in Australian commercial property returns. However, the results also indicate that forecast accuracy in these …
Stochastic Price Modelling Of High Volatility, Mean-Reverting, Spike-Prone Commodities: The Australian Wholesale Electricity Market, Andrew C. Worthington, Helen Higgs
Stochastic Price Modelling Of High Volatility, Mean-Reverting, Spike-Prone Commodities: The Australian Wholesale Electricity Market, Andrew C. Worthington, Helen Higgs
Faculty of Commerce - Papers (Archive)
It is commonly known that wholesale spot electricity markets exhibit high price volatility, strong mean-reversion and frequent extreme price spikes. This paper employs a basic stochastic model, a mean-reverting model and a regime-switching model to capture these features in the Australian national electricity market (NEM), comprising the interconnected markets of New South Wales, Queensland, South Australia and Victoria. Daily spot prices from 1 January 1999 to 31 December 2004 are employed. The results show that the regimeswitching model outperforms the basic stochastic and mean-reverting models. Electricity prices are also found to exhibit stronger mean-reversion after a price spike than in …

Place-based belonging is a key concern of geographical work on sexuality. Marginalised through practices of heterosexism and homophobia, gay men, lesbians and other sexual minorities have a heightened awareness of where they belong – of where they can perform sexual difference. Much research here focuses on place-based belonging in metropolitan centres. There is less consideration of how sexual minorities sustain place-based belonging in regional centres, which are also believed to exhibit higher levels of homophobia. Drawing on in-depth interviews, we examine how sexual minorities generate place-based belonging in Townsville. We argue that place-based belonging be understood as an ongoing relational …

The Australian artworld has never looked better. There are more art journals, exhibition spaces and art graduates than ever. Even globalisation has been a boon to local artists, especially indigenous ones. But there is a catch. There may be plenty of interesting artists from Australia but few aspire to make Australian art. If Rex Butler is right, the desire now is for 'unAustralian' art.

Prehistoric depositional signatures for large-scale washover involving marine inundation events such as storm and tsunami have been the subject of considerable research over the last 15 years. Much of this research has focused on the identification of sand sheets in back-barrier environments as depositional records for extreme washover events. All these deposits must have a sediment source, and by their nature, the most likely source of sediment for washover into back-barrier environments is the barrier itself. This study identifies an erosional signature for large-scale washover from a small coastal barrier on the southeast Australian coast. A distinct lense of marine …

M-commerce, a growing sub-category of E-business, allows business to be done 'anywhere, anytime'. However security of wireless devices remains problematic. It is unclear whether protocols to alleviate security problems, such as wireless vulnerability assessments (WNVAs), are being used or are effective. The paper reports on a survey-based study of Australian computer security professionals' use of and opinions about two types of WNVA: wireless monitoring and penetration testing. An initially surprising finding was how little both types are used, despite the ease with which wireless networks can be attacked and the fact that penetration testing is fairly well understood. In the …
