Updating The Dietadvice Website With New Australian Food Composition Data, Yasmine Probst, Holley-Anne Jones, Shannon Lin, S. Burden, David G. Steel, Linda C. Tapsell

Professor David Steel

DietAdvice is an Australian self-administered dietary assessment website initially developed in 2003- 2005. The website allows patients to enter their dietary information and dieticians to remotely access and interpret the data. DietAdvice is presently being updated with new Australian food composition data. This study aims to describe the update process for moving from 1995 to 2006 food composition data. The database for the website was developed using grouped food data from the NUTTAB 1995 database. All food groups were cross-matched with the food from the NUTTAB 2006 database using the food ID codes. Rules were applied to determine the suitability …

Taxation And The Australian Superannuation System: An International Comparison, Corinne Cortese, John Glynn

John J Glynn

This study demonstrates the taxation burden applied to Australian superannuation. The superannuation schemes and supporting taxation systems of five OECD countries are reviewed. A hypothetical scenario is applied to demonstrate the imbalance of the Australian system relative to comparable nations. Given concerns about the aging population, this research supports calls for further reforms to the taxation of superannuation in Australia, highlighting the need to make superannuation taxation policies more consistent with government efforts to encourage superannuation savings and self-funded retirement.

Our Retirement In Their Hands: A User Perspective, Cotinne Cortese, David Aylward, John Glynn

John J Glynn

This research reports on the results of a survey of Australian retirees which provide information on attitudes surrounding financial planning advice before, at or after retirement. These results demonstrate that, despite government initiatives aimed at enhancing consumer confidence in the financial services market, most retirees continue to feel dissatisfied with, and lack confidence in, the services provided by their financial advisors. This suggests an increased role for financial planners to provide not only the additional information required under government policy, but also to provide information that is understandable and useful to the retirees that rely on it.

Unit Root Tests And Structural Breaks: A Survey With Applications, John Glynn, Nelson Perera, Reetu Verma

John J Glynn

The theme of unit roots in macroeconomic time series have received a great amount of attention in terms of theoretical and applied research over the last three decades. Since the seminal work by Nelson and Plosser (1982), testing for the presence of a unit root in the time series data has become a topic of great concern. This issue gained further momentum with Perron’s 1989 paper which emphasized the importance of structural breaks when testing for unit root processes. This paper reviews the available literature on unit root tests taking into account possible structural breaks. An important distinction between testing …

Organization-Based Social Marketing: An Alternative Approach For Organizations Adopting Sustainable Business Practices, Mary Franks Papakosmas, Gary Noble, John Glynn

John J Glynn

This article conceptualizes a new area for social marketing practitioners by focusing on individual behavior change that might occur within organizations. Organization-Based Social Marketing (OBSM) draws from organization change theory and internal marketing theory, while maintaining social marketing’s focus on beneficial behavior modification. The article argues that as such, OBSM represents a viable approach for organizations seeking to address the increasing demand for change strategies that promote proenvironmental behavior among their employees

Air-Drying Of Banana: Influence Of Experimental Parameters, Slab Thickness, Banana Maturity And Harvesting Season, Minh-Hue Nguyen, William E. Price

William E. Price

Air-drying of banana slabs has been investigated and the influence of experimental parameters such as temperature, relative humidity and slab thickness has been studied. This was in part re-investigated because of inconsistencies in previous studies, particularly in relation to derived water diffusion coefficients. In addition, it is shown that harvest season and hence initial moisture content has a very marked influence on the drying kinetics. By contrast banana maturity (ripeness) has little influence on the kinetics despite there being significant differences in morphology and chemical composition between green and ripe bananas. The effect of these two variables on the drying …

Increased Probiotic Yogurt Or Resistant Starch Intake Does Not Affect Isoflavone Bioavailability In Subjects Consuming A High Soy Diet, Theresa A. Larkin, William E. Price, Lee B. Astheimer

William E. Price

Objective: Probiotics and prebiotics that affect gut microflora balance and its associated enzymeactivity may contribute to interindividual variation in isoflavone absorption after soy intake, possiblyenhancing isoflavone bioavailability. This study examined the effects of the consumption ofbioactive yogurt (a probiotic) or resistant starch (a known prebiotic) in combination with high soyintake on soy isoflavone bioavailability.Methods: Using a crossover design, chronic soy consumption was compared with soy plusprobiotic yogurt or resistant starch in older male and postmenopausal females (n 31). Isoflavonebioavailability was assessed at the beginning and end of each 5-wk dietary period by samplingplasma and urine after a standardized soy meal.Results: …

Fractionation Of Sedimentary Arsenic From Port Kembla Harbour, Nsw, Australia, Glennys A. O'Brien, William E. Price, Bryan E. Chenhall, Muhammad Damris

William E. Price

The binding of arsenic in sediments of the heavily industrialised Port Kembla Harbour, NSW, Australia, has been investigated. Both dredge and core samples have been used to develop a sieving/sequential extraction (SE) procedure. Dredge samples included oxic surficial and deeper anoxic sediment. The main core sample analysed was 18 cm deep, sliced at 2 cm intervals. Sediment was sieved to three size ranges (250 microm) and each of these was then subjected to a four step SE, sequentially solubilizing arsenic as ion exchangeable, 1 M HCl soluble, NH(2)OH.HCl soluble, and strong oxidising acid soluble. Concentrations of 50-500 mg As kg(-1) …

A Fragmentation Study Of Isoflavones In Negative Electrospray Ionization By Msn Ion Trap Mass Spectrometry And Triple Quadrupole Mass Spectrometry, Jinguo Kang, Larry A. Hick, William E. Price

William E. Price

This study has elucidated the fragmentation pathway for deprotonated isoflavones in electrospray ionization using MSn ion trap mass spectrometry and triple quadrupole mass spectrometry. Genistein-d4 and daidzein-d3 were used as references for the clarification of fragment structures. To confirm the relationship between precursor and product ions, some fragments were traced from MS2 to MS5. The previous literature for the structurally related flavones and flavanones located the loss of ketene (C2H2O) to ring C, whereas the present fragmentation study for isoflavones has shown that the loss of ketene occurs elsewhere at ring A. In the further fragmentation of the [M-H-CH3]•- radical …

Tissue Distribution Of Lignans In Rats In Response To Diet, Dose-Response, And Competition With Isoflavones, Timothy Murray, J. Kang, Lee Astheimer, William E. Price

William E. Price

This paper investigates the occurrence and distribution of the lignan metabolites enterodiol (END) and enterolactone (ENL) and the isoflavone daidzein (DAID) in rat tissues using liquid chromatography - electrospray ionisation mass spectrometry (LC – ESI/MSn) following a variety of dietary regimes. Further, we examined the dose-response and distribution of END and ENL in liver, testes, prostate and lung, and investigated the effects of competition between lignans and isoflavones on metabolite distribution. In liver, testes, prostate & lung tissue, dose related increases in END concentration were observed. In the testes, the co-administration of 60 mg/kg SDG with 60 mg/kg isoflavones produced …

Effect Of Organic Solvents On The Separation Of Benzoic Acids By Capillary Electrophoresis, Young J. Lee, William E. Price, Margaret Sheil

William E. Price

The effect of organic modifiers on the separation of a number of closely related isomeric benzoic acids by capillary electrophoresis is described. It is shown that while a single modifier concentration cannot help resolve the entire electropherogram, organic modifiers do significantly enhance the resolution of parts of the separation system by comparison with 40 mmol l-1 phosphate buffer. The effects on separation and retention times are discussed in terms of the effects on electroosmotic flow and the electrophoretic mobilities of the charged solutes. The effects were found to be modifier specific, although the trends were in the same direction (ie., …

Occurrence Of Phytoestrogens In Municipal Wastewater And Surface Waters, Jinguo Kang, William E. Price

William E. Price

Phytoestrogens (isoflavones, enterolignans and coumestrol) in wastewater samples and surface water samples have been analysed by LC-ESI-MSn. In wastewater samples, high levels of enterolactone (581 – 2111 ng/L), daidzein (341 – 1688 ng/L) and enterodiol (60 – 834 ng/L) were detected in raw sewage, but the vast majority of the analysed phytoestrogens were removed effectively in treatment process. The removal rates of the analysed phytoestrogens in the two advanced tertiary treatment plants were > 99%; a case study in one of the treatment plants showed that most of the residual phytoestrogens were removed by biological treatment using activated sludge. In surface …

The Effect Of Dextran On Subunit Exchange Of Αa-Crystallin, A. Ghahghaei, A. Rekas, W. E. Price, J. A. Carver

William E. Price

α-Crystallin, a member of small heat shock protein (sHsp) family, is comprised of αA and αB subunits and acts as a molecular chaperone by interacting with unfolding proteins to prevent their aggregation. The αA-crystallin homopolymer consists of 30-40 subunits that are undergoing dynamic exchange. α-Crystallin and αA-crystallin are poorer chaperones in the presence of the crowding agent, dextran. Using fluorescence resonance energy transfer, it is shown that the αAcrystallin subunit exchange rate strongly increased with temperature. Binding of reduced ovotransferrin to αA-crystallin markedly decreases the rate of subunit exchange, as does the presence of dextran. In addition, in the presence …

The Key Importance Of Soy Isoflavone Bioavailability To Understanding Health Benefits, T. A. Larkin, William E. Price, L. Astheimer

William E. Price

Research over the past two decades has provided significant epidemiological and other evidence for the health benefits of the consumption of soy-based foods. A large number of dietary intervention studies have examined the effects of soy isoflavones on risk factors for cardiovascular disease and hormone-dependent cancers. However, these report large variability in outcome measures, very limited reproducibility between studies and in some cases, controversy between results of clinical trials using dietary soy or soy protein and isoflavone supplementation. This highlights a major gap in our understanding of soy isoflavone uptake, metabolism, distribution, and overall bioavailability. There are many potential factors …

Using Calibration Approaches To Compensate For Remaining Matrix Effects In Quantitative Liquid Chromatography Electrospray Ionization Multistage Mass Spectrometric Analysis Of Phytoestrogens In Aqueous Environmental Samples, Jinguo Kang, Larry A. Hick, William E. Price

William E. Price

Signal suppression is a common problem in quantitative LC-ESI-MSn analysis in environment samples, especially in highly loaded wastewater samples with highly complex matrix. Optimization of sample preparation and improvement of chromatographic separation are prerequisite to improve reproducibility and selectivity. Matrix components may be reduced if not eliminated by a series of sample preparation steps. However, extensive sample preparation can be time-consuming and risk the significant loss of some trace analytes. The best way to further compensate matrix effects is the use of internal standard for each analyte. However, in a multi-component analysis, finding appropriate internal standards for every analyte is …

The Veneer Is Radical, The Substance Is Not, Evan S. Poata-Smith

Evan S. Te Ahu Poata-Smith

Ranginui Walker's history of the Maori struggles for tino rangatiratanga (self-determination) was first published during New Zealand’s sesquicentennial year. The 150th anniversary of the signing of the Treaty of Waitangi provoked intense public debates around issues of nationhood and the place of the Treaty of in managing contemporary relationships between Maori communities and the Crown.

August 26, 2001 Two Or Three Things Australians Don't Seem To Want To Know About 'Asylum Seekers', Ian Buchanan

Ian M Buchanan

The road to war began with an incident at sea, as it has so many times in the past - the sinking of the Lusitania, Pearl Harbour, the Gulf of Tonkin, and so on. History will have to record that Australia’s involvement in the ‘War on Terror’ and the ‘War against Iraq’ began on August 26, 2001 when the MV Tampa rescued 433 asylum seekers from the sinking ferryboat, Palapa 1. It will then have to explain how this essentially humanitarian act could trigger so bellicose a response. To do this, it will not be enough to condemn the cynical …

War In The Age Of Intelligent Machines And Unintelligent Government, Ian Buchanan

Ian M Buchanan

The 2004 US election must have caused hearts to sink everywhere in the Third World. The bloody insurgency in Iraq only strengthened the position of the 'War President', giving him greater license to continue his campaign of terror. Atthe time of the election the death toll of US soldiers was nearing a thousand with the number injured seven times that. To which toll one must add the haunting fact that of the 500 000 plus US servicemen and women who served in theFirst Gulf War some 325 000 are now on disability pensions suffering a variety of acute maladies generally …

Renovating Reality Tv, Ian Buchanan

Ian M Buchanan

The Block was Australia's hit TV show of 2003. Its viewing audience regularly topped the 2 million mark, easily surpassing all the other 'lifestyle' shows - DIY Rescue, Burke's Backyard, Backyard Blitz, Changing Rooms, Better Homes and Gardens , Location Location, Auction Squad, Hot Auctions , the list is practically endless. Australian made TV drama has meanwhile delivered its worst ratings performance in years, virtually guaranteeing The Block will not only be repeated but cloned as well. David Castran, the managing director of Audience Development Australia, explains it this way: "recent world turmoil has brought people closer to home to …

Desire And Ethics, Ian M. Buchanan

Ian M Buchanan

This paper argues that it is problematic for the future of Deleuze studies that it is difficult if not impossible to answer the question `what is the right thing to do?' from a Deleuzian perspective. It then argues that one of the key reasons Deleuze studies has made limited progress in this area is its over-emphasis on desire and the corresponding tendency to extrapolate 'ought' from 'is', which as Hume showed is a category mistake. It proposes that to develop a workable ethical discourse from Deleuze's work we need to rethink how we read his work and approach it afresh.

Enjoying 'Reality Tv', Ian Buchanan

Ian M Buchanan

Big Brother, Boot Camp, Castaway, Shipwrecked, and the oh-so-glamorous Survivor, how much 'Reality TV' can we stand? More to the point, why do we want any of it? In other words, why do any of these shows even exist, what fantasy need do they fulfil? The temptation to invoke 'voyeurism' at this point is almost irresistible and is to be resisted for precisely that reason; the ease with which it seems to answer the questions begged by 'Reality TV' should be sufficient to alert us that it is what de Certeau calls a 'black sun', that is, something which however …

Misrecognition In Titanic, Ian Buchanan

Ian M Buchanan

Something rather interesting is going on in Hollywood cinema today. Art is being used to deflect feminist inquiry; but more incredibly still, feminist self-assertion is being used to avert a critique of capitalism. I am thinking particularly of the nude scene in Titanic. Kate Winslett appears nude, but because it is for an artist, not us, as it were, that nudity is contained, recuperated in other words, by being made to seem other than it is. And since the scene is a peripeteia in the Hollywood sense of the word, namely a moment of self-discovery, the resulting artwork is coded …

Consumers' Salient Beliefs Regarding Dairy Products In The Functional Food Era: A Qualitative Study Using Concepts From The Theory Of Planned Behaviour, Deborah Nolan, Elizabeth Neale, Yasmine Probst, Karen E. Charlton, Linda C. Tapsell

L. C. Tapsell

Background Inadequate consumption of dairy products without appropriate dietary substitution may have deleterious health consequences. Social research reveals the factors that may impede compliance with dietary recommendations. This is particularly important given the recent introduction of functional dairy products. One of the challenges for public health professionals is to demonstrate the efficacy of nutrition education in improving attitudes toward nutrient rich foods. The aim of this study was to explore the salient beliefs of adult weight loss trial participants regarding both traditional and functional dairy products and to compare these with a control group not exposed to nutrition education Methods …

Fat In Food And The Obesity Epidemic, Linda C. Tapsell

L. C. Tapsell

Dietary fat is strongly implicated in the development of insulin resistance and obesity, both major public health problems today. While the amount of dietary fat is relevant, the type of fat is important in fuel utilisation, storage and appetite regulatory mechanisms. Human calorimetry research confirms the importance of dietary fat in energy balance, but more work needs to be done to uncover the impact of type of dietary fat in weight control. Population and intervention research confirm the importance of fat in dietary interventions, bearing in mind the contribution of physical activity to energy balance. The food industry has an …

Increased Intake Of Dietary Polyunsaturated Fat Does Not Promote Whole Body Or Preferential Abdominal Fat Mass Loss In Overweight Adults, Sze-Yen Tan, Marijka Batterham, Linda Tapsell

L. C. Tapsell

Objective: There is evidence that increasing the proportion of polyunsaturated fatty acids (PUFA) in a diet can enhance the rate of fat oxidation acutely. Higher PUFA in a diet has also been associated with greater abdominal fat loss in longer term studies. This study aimed to investigate if higher PUFA intake would result in greater fat mass loss over a 12-week period, mainly from the abdominal region.

Methods: Data at the 12-week time point from two weight loss studies, both comparing high PUFA versus low PUFA diets was, accessed for 141 overweight subjects from the same area. Specifically, data on …
