A Case Study Of Sodium Reduction In Breakfast Cereals And The Impact Of The Pick The Tick Food Information Program In Australia, P. G. Williams, A. Mcmahon, R. Boustead

Faculty of Health and Behavioural Sciences - Papers (Archive)

In 1997 one of Australia’s largest food companies undertook a program of salt reduction in 12 breakfast cereals. The National Heart Foundation’s Pick the Tick program criterion (<400mg>sodium/100g) was used as a target value where possible. Twelve products were reformulated, with reductions ranging from 85-469mg sodium per 100g and an average reduction of 40% (12-88%). As a result, 235 tonnes of salt were removed annually from the Australian food supply and five more products were able to carry the Tick logo. The impact of the Pick the Tick program in changing the food supply extends beyond those products that …

Objective The aim of this study was to develop a questionnaire for use by nutrition professionals to enable evaluation of popular diet books.

Design A questionnaire was developed incorporating quantified criteria based on current authoritative nutrition guidelines. Twenty two questions were included, relating to nutritional adequacy, daily energy allowance, recommended rate of weight loss, flexibility and sustainability, physical activity advice, use of supplements, claims, author’s credentials, and scientific evidence. The questionnaire was used to rate 35 diets in 20 popular diet books sold in Australia in 2001, in order to test its practicality, validity and sensitivity. A computerised dietary analysis …

Nutrition And Related Claims Used On Packaged Australian Foods - Implications For Regulation, P. G. Williams, H. Yeatman, S. Zakrzewski, B. Aboozaid, S. Henshaw, K. Ingram, A. Rankine, S. Walcott, F. Ghani

Faculty of Health and Behavioural Sciences - Papers (Archive)

The aim of this study was to describe the use of nutrition and related claims on packaged food for sale in Australia and measure the compliance of such claims with regulations governing their use. A survey was conducted of the labelling of 6662 products in 40 different food categories on sale in New South Wales in 2001. Levels of compliance were assessed by comparing the claims on the label and data in the nutrition information panel with requirements of the Foods Standards Code and the Code of Practice on Nutrient Claims. Half of the products (51.3%) carried some type of …

Sexism Is In The Eye Of The Beholder: Does The Advertising Standards Board Reflect "Community Standards"?, Sandra C. Jones

Faculty of Health and Behavioural Sciences - Papers (Archive)

This study examines the Advertising Standards Board’s response to complaints lodged against advertisements between 1999 and 2001 under sub-section 2.3 of the AANA Code (portrayal of sex/sexuality/nudity). Between 1999 and 2001, the ASB considered 419 complaints lodged by members of the general public under this subsection of the Code, of which only three were upheld. The decisions reported in the ASB’s Case Reports for these three years are examined by assessing three advertisements from each of these years (including the only one in each year against which a complaint was upheld). Inconsistencies in the application of this sub-section of the …

Are Current Social Marketing Campaigns Getting Through To Undergraduate University Students?, Sandra C. Jones

Faculty of Health and Behavioural Sciences - Papers (Archive)

In this study, we conduct a survey of health behaviours among undergraduate university students. The health behaviours include weight control, exercise, smoking, alcohol consumption, use of illicit drugs, and safe-sex practices. By comparing the results with national survey results, we test the hypothesis that university students – who have completed high school, with better than average grades – are more likely to exhibit healthy behaviours and avoid unhealthy or unsafe behaviours than the general population. Detailed information on the health behaviours of university students is not currently available (see Australia’s Health 2000, in which there are no reports of health …

Consumer Confusion: Parents Nutritional Perceptions Of Food Advertisements, Christina Hoang, Sandra C. Jones, Jennifer Thornton

Faculty of Health and Behavioural Sciences - Papers (Archive)

Due to the increasing prevalence of childhood obesity in society, this study was undertaken to determine if advertisers could potentially be misleading parents through the nutritional claims made in advertisements for popular children’s food products. Research was conducted to determine the sorts of nutritional messages parents received from four food advertisements. In total, 41 parents from an Australian university childcare centre participated in the study. The results revealed several major discrepancies whereby parents’ perceived unhealthy products to be healthy – indicating a degree of consumer confusion among parents.

Believability And Effectiveness Of Young Adult Safe-Drinking Messages, N. Breen, Sandra C. Jones

Faculty of Health and Behavioural Sciences - Papers (Archive)

This study investigates eight safe-drinking messages, using appeals to the ‘self’ versus appeals about ‘others’, in combination with either a low or high physical threat, or a low or high social threat. The participants were18-25 year old second-year university marketing students. An experimental design was used for data collection, which involved 196 participants, with the groups comprised of participants with homogenous demographic characteristics and drinking behaviour. Analysis of variance (ANOVA) was used to test the believability and effectiveness of the messages. It was determined that messages about ‘others’ were perceived as more believable and effective than the corresponding appeals used …

Recognising Facial Expression From Spatially And Temporally Modified Movements, Frank E. Pollick, Harold C. Hill, Andrew Calder, Helena Paterson

Faculty of Health and Behavioural Sciences - Papers (Archive)

We examined how the recognition of facial emotion was influenced by manipulation of both spatial and temporal properties of 3-D point-light displays of facial motion. We started with the measurement of 3-D position of multiple locations on the face during posed expressions of anger, happiness, sadness, and surprise, and then manipulated the spatial and temporal properties of the measurements to obtain new versions of the movements. In two experiments, we examined recognition of these original and modified facial expressions: in experiment 1, we manipulated the spatial properties of the facial movement, and in experiment 2 we manipulated the temporal properties. …

Linking The Structure And Perception Of 3-D Faces: Gender, Ethnicity And Expressive Posture, Guillaume Vignali, Harold C. Hill, Eric Vatikiotis-Bateson

Faculty of Health and Behavioural Sciences - Papers (Archive)

A statistical study of human face shape is reported whose overall goal was to identify and characterise salient components of facial structure for human perception and communicative behaviour. A large database of 3-D faces has been constructed and analysed for differences in ethnicity, sex, and posture. For each of more than 300 faces varying in race/ethnicity (Japanese versus Caucasian) and sex, nine postures (smiling, producing vowels, etc) were recorded. Principal components analysis (PCA) and linear discriminant analysis (LDA) were used to reduce the dimensionality of the data and to provide simple, yet reliable reconstruction of any face from components corresponding …

Psychology And The Enhancement Of Medication Adherence, Mitchell K. Byrne, Frank P. Deane

Faculty of Health and Behavioural Sciences - Papers (Archive)

This paper reports on a new approach to the enhancement of medication adherence - Medication Alliance. Medication Alliance was developed and piloted by a project team that includes Mitch Byrne as project leader, Frank Deane as research supervisor, and two consultants, Tim Coombs and Gordon Lambert. Because Medication Alliance borrows heavily from psychological principles such as functional analysis and cognitive therapy, this presentation is entitled 'Psychology and the Enhancement of Medication Adherence '. However, Medication Alliance is a non-discipline specific therapy approach that fits well within the purview of any clinician delivering psychosocial interventions. The theoretical underpinnings of the various …

Coherent Perspective Jitter Induces Visual Illusions Of Self-Motion, Stephen A. Palmisano, Darren Burke, Robert S Allison

Faculty of Health and Behavioural Sciences - Papers (Archive)

Previous research by Palmisano, Gillam and Blackburn (2000) found that adding coherent perspective jitter to constant velocity radial flow improved visually induced illusions of self-motion (known as vection). This was a surprising finding, because unlike pure radial flow, this jittering radial flow should have generated sustained visual-vestibular conflicts - previously thought to always reduce/impair vection. The current experiments attempted to ascertain the essential stimulus features for this jitter advantage for vection by examining three novel types of jitter display. While adding incoherent jitter to radial flow was found to impair vection, adding coherent non-perspective jitter had little effect on this …

Introduction Of Behavioural Based Safety, Ian Price

Faculty of Science, Medicine and Health - Papers: part A

Behavioural Based Safety in the workplace is the application of industrial or organisational psychology to promote health and safety (I). Our own complexities makes us all fallible, whether it be from the fact we love to push the boundaries, challenge authority, cognitive failures, memory lapse, processing errors or personal health related problems, we make mistakes (2). Generally thought as a species we do try to do the right thing, co-operate with one another, and don't go out of our way to be disobedient or want to cause physical harm or damage. Behavioural Based Safety can be said to be a …

An Archaeology Of Historical Reality?: A Case Study Of The Recent Past, Alistair Paterson, Nicholas Gill, M.J. Kennedy

Faculty of Science, Medicine and Health - Papers: part A

An Aboriginal elder, an archaeologist and a geographer report on an interdisciplinary project about colonial-era settlement in the Murchison and Davenport ranges in the Northern Territory. Oral history, physical evidence and historical records reveal a distinct central Australian cultural landscape and show that archaeology can do more than merely exhume material to support historical 'realities'. This project provides new or improved understandings of (1) colonial technology in pastoral ventures, (2) continuity and change in Aboriginal life following European arrival, (3) social behaviour in colonial settings, and (4) alternatives to Eurocentric Australian histories.

Poisoned Patients As Potential Organ Donors: Postal Survey Of Transplant Centres And Intensive Care Units, David Michael Wood, Paul Ivor Dargan, Alison L. Jones

Faculty of Science, Medicine and Health - Papers: part A

Background The number of patients awaiting allograft transplantation in the UK exceeds the number of organs offered for transplantation each year. Most organ donors tend to be young, fit and healthy individuals who die because of trauma or sudden cardiac arrest. Patients who die from drug and poison intoxication tend to have similar characteristics but are less frequently offered as potential organ donors. Methods A postal questionnaire survey of all transplantation centres and an equal number of intensive care units in the UK was undertaken. The use of kidney, heart, lung, liver and pancreas transplants from poisoned patients following deliberate …

Disturbance-Mediated Competition And The Spread Of Phragmites Australis In A Coastal Marsh, Todd Minchinton, Mark D. Bertness

Faculty of Science, Medicine and Health - Papers: part A

In recent decades the grass Phragmites australis has been aggressively invading coastal, tidal marshes of North America, and in many areas it is now considered a nuisance species. While P. australis has historically been restricted to the relatively benign upper border of brackish and salt marshes, it has been expanding seaward into more physiologically stressful regions. Here we test a leading hypothesis that the spread of P. australis is due to anthropogenic modification of coastal marshes. We did a field experiment along natural borders between stands of P. australis and the other dominant grasses and rushes (i.e., matrix vegetation) in …

Mid-Late Holocene El Nino Variability In The Equatorial Pacific From Coral Microatolls, Colin Woodroffe, Matthew R. Beech, Michael K. Gagan

Faculty of Science, Medicine and Health - Papers: part A

Oxygen isotope ratios in Porites microatolls from Christmas Island in the central Pacific provide high-resolution proxy records of El Niño-Southern Oscillation (ENSO) variability since 3.8 thousand years ago (ka). Compared with modern microatolls, reconstructions from fossil microatolls imply that interannual variations in ENSO sea-surface temperature and precipitation were less intense 3.8–2.8 ka, but more pronounced at 1.7 ka. Amplification of ENSO at ∼2 ka is consistent with precessional changes in insolation seasonality, but exceeds model predictions and may reflect stronger rainfall teleconnections through enhanced interaction between the Southern Oscillation and the Pacific Intertropical Convergence Zone.

Cell Surface Antigens Of Mycoplasma Species Bovine Group 7 Bind And Activate Plasminogen, Kylie Bower, Steven Djordjevic, Nicholas M Andronicos, Marie Ranson

Faculty of Science, Medicine and Health - Papers: part A

Mycoplasma species bovine group 7 bound plasminogen at the cell surface in a lysine-dependent manner. Cell-bound plasminogen was rapidly activated to plasmin by exogenous urokinase, and this activity was associated with plasminogen binding capacity. Binding assays using plasminogen modified with a trifunctional cross-linking agent revealed several binding proteins.

Work-Based Physiological Assessment Of Physically-Demanding Trades: A Methodological Overview, Nigel A.S. Taylor, Herbert Groeller

Faculty of Science, Medicine and Health - Papers: part A

Technological advances, modified work practices, altered employment strategies, work-related injuries, and the rise in work-related litigation and compensation claims necessitate ongoing trade analysis research. Such research enables the identification and development of gender- and age-neutral skills, physiological attributes and employment standards required to satisfactorily perform critical trade tasks. This paper overviews a methodological approach which may be adopted when seeking to establish trade-specific physiological competencies for physically-demanding trades (occupations). A general template is presented for conducting a trade analyses within physically-demanding trades, such as those encountered within military or emergency service occupations. Two streams of analysis are recommended: the trade …

Bovine Non-O157 Shiga Toxin 2-Containing Escherichia Coli Isolates Commonly Possess Stx2-Edl933 And/Or Stx2vhb Subtypes, Kim Brett, Michael A Hornitzky, Karl A Bettelheim, Mark J. Walker, Steven Djordjevic

Faculty of Science, Medicine and Health - Papers: part A

stx₂ genes from 138 Shiga toxin-producing Escherichia coli (STEC) isolates, of which 127 were of bovine origin (58 serotypes) and 11 of human origin (one serotype; O113:H21), were subtyped. The bovine STEC isolates from Australian cattle carried ehxA and/or eaeA and predominantly possessed stx_2-EDL933 (103 of 127; 81.1%) either in combination with stx_2vhb (32 of 127; 25.2%) or on its own (52 of 127; 40.4%). Of 22 (90.9%) bovine isolates of serotype O113:H21, a serotype increasingly recovered from patients with hemolytic uremic syndrome (HUS) or hemorrhagic colitis, 20 contained both stx_2-EDL933 and stx_2vhb; 2 …

Towards A Sounder Fire Ecology, Edward A. Johnson, A Malcolm Gill, Ross Bradstock, Anders Granstrom, Louis Trabaud, Kiyoko Miyanishi

Faculty of Science, Medicine and Health - Papers: part A

This forum brings together fire ecologists from outside the current wildfire controversy in the US to give their views on three central topics related to ecosystems in which wildfires are an important process. First, how do fire behavior and ecological effects vary between ecosystems? Second, why does this variation require an understanding that goes beyond simple correlations between various fire and ecosystem variables to more careful causal models? Third, how can human values and goals be reconciled with fire disturbance processes in an ecologically sound manner?

Intercomparison Of Ndsc Ground-Based Solar Ftir Measurements Of Atmospheric Gases At Lauder, New Zealand, D W. T Griffith, Nicholas Jones, B Mcnamara, Clare Paton-Walsh, W. R. Bell, Cirilo Bernado

Faculty of Science, Medicine and Health - Papers: part A

A formal intercomparison of atmospheric total column measurements of N₂O, N₂, CH₄, O₃, HCl, HNO₃, and HF by two ground-based solar Fourier transform infrared (FTIR) spectrometers conducted as part of the Network for the Detection of Stratospheric Change (NDSC) instrument certification procedure at Lauder, New Zealand, is presented. The two instruments were nominally very similar, collocated, and collected data at the same times. Collected spectra were analyzed independently by the individual operators in a blind-phase intercomparison, then reanalyzed by a single operator using identical analysis methods to eliminate any potential …

Stx1c Is The Most Common Shiga Toxin 1 Subtype Among Shiga Toxin-Producing Escherichia Coli Isolates From Sheep But Not Among Isolates From Cattle, Kim Brett, Vidiya Ramachandran, Michael A Hornitzky, Karl A Bettelheim, Mark J. Walker, Steven P. Djordjevic

Faculty of Science, Medicine and Health - Papers: part A

Unlike Shiga toxin 2 (stx₂) genes, most nucleotide sequences of Shiga toxin 1 (stx₁) genes from Shiga toxin-producing Escherichia coli (STEC), Shigella dysenteriae, and several bacteriophages (H19B, 933J, and H30) are highly conserved. Consequently, there has been little incentive to investigate variants of stx₁ among STEC isolates derived from human or animal sources. However stx_1OX3, originally identified in an OX3:H8 isolate from a healthy sheep in Germany, differs from other stx₁ subtypes by 43 nucleotides, resulting in changes to 12 amino acid residues, and has been renamed stx_{1c …}

Dehydration And Partial Melting In Subduction Zones: Constraints From U-Series Disequilibria, Bernard Bourdon, Simon Turner, Anthony Dosseto

Faculty of Science, Medicine and Health - Papers: part A

We present a critical reappraisal of U-series data from arc volcanoes to constrain slab dehydration and melting processes using a global subduction zone data set. There is no clear evidence for significant mobilization of Th or Pa in dehydration fluids while the source region of arc rocks is relatively oxidized and mobility of U is strongly enhanced. It is argued that along-arc U/Th and U/Pa isotope data reflect time-integrated addition of U from the slab to the mantle wedge. The presence of large Ra-Th disequilibrium correlated with Ba/Th ratios provides evidence for some very recent fluid addition and fast magma …
