Sea Surface Temperature And Chlorophyll-A Spatial-Temporal Variation Using Modis-Aqua In The Todos Os Santos Bay, Bahia, Brazil, Rafael Cabral Carvalho, Carlos A. Lentini

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

In this study, the importance of MODIS sensor multispectral imagery on monitoring coastal and oceanic areas as well as marine ecosystems is demonstrated. As an example, the Todos os Santos Bay (TSB), BA, Brazil, was selected. Four 250m Sea Surface Temperature and Chlorophyll-a satellite-derived images were processed to characterize the TSB in 2009, as well as monthly time-series from July 2002 to January 2010 and monthly maps of 2009 off the coast of Bahia. These results were compared to the Brazilian Water Agency (ANA) discharge data and tidal data. They showed the importance of the latter in physical forcing compared …

Does Aging Change Docosahexaenoic Acid Homeostasis? Implications For The Challenge To Cognitive Health In The Elderly, Christian-Alexandre Castellano, Raphael Chouinard-Watkins, J Tom Brenna, Barbara J. Meyer, Stephen C. Cunnane Jan 2011

Does Aging Change Docosahexaenoic Acid Homeostasis? Implications For The Challenge To Cognitive Health In The Elderly, Christian-Alexandre Castellano, Raphael Chouinard-Watkins, J Tom Brenna, Barbara J. Meyer, Stephen C. Cunnane

Faculty of Health and Behavioural Sciences - Papers (Archive)

Epidemiological studies fairly convincingly suggest that higher intake of fish and omega-3 fatty acids present in fish is associated with reduced risk for age-related cognitive decline (ARCD). Normally, docosahexaenoic acid (DHA) in plasma is positively associated with DHA intake. However, despite being associated with lower fish and DHA intake, unexpectedly, ARCD is not consistently associated with lower plasma DHA. Furthermore, DHA is often slightly but significantly higher in plasma and erythrocytes in the elderly without ARCD compared to young adults. Higher plasma DHA in the elderly may be a sign that their fish or DHA intake is higher but we …

Face Viewpoint Effects About Three Axes: The Role Of Configural And Featural Processing, Simone K. Favelle, Stephen A. Palmisano, Georgina Avery

Faculty of Health and Behavioural Sciences - Papers (Archive)

We directly compared recognition for faces following 0° – 75° viewpoint rotation about the yaw, pitch, and roll axes. The aim was to determine the extent to which configural and featural information supported face recognition following rotations about each of these axes. Experiment 1 showed that performance on a sequential-matching task was viewpoint-dependent for all three types of rotation. The best face-recognition accuracy and shortest reaction time was found for roll rotations, then for yaw rotations, and finally the worst accuracy and slowest reaction time was found for pitch rotations. Directional differences in recognition were found for pitch rotations, but …

Implementation And Evaluation Of A Community-Based Social Marketing Campaign To Create Awareness Of Hypertension As A Risk Factor For Dementia, Kelly Andrews, Lyn Phillipson, Sandra C. Jones, Danika Hall, J. Potter, Gaye Sykes

Faculty of Health and Behavioural Sciences - Papers (Archive)

As the Australian population ages, the incidence of dementia is rising in epidemic proportions, with serious implications for sufferers, carers and health services. There is a compelling need for effective early intervention and prevention strategies as well as models to guide knowledge translation to improve dementia prevention and care. The most modifiable risk factor for dementia is hypertension and treating hypertension in midlife is the most effective means of reducing dementia risk, yet public awareness of this is extremely low. The purpose of this pilot project was to plan, implement and evaluate a social marketing campaign to raise community awareness …

Unravelling Some Of The Complexities Concerning The Neural Control Of Human Eccrine Sweating, Christiano A. Machado-Moreira, Peter L. Mclennan, Stephen Lillioja, Joanne N. Caldwell, Wilko Van Dijk, Nigel A. S Taylor

Faculty of Health and Behavioural Sciences - Papers (Archive)

The widely accepted, though not unequivocal, opinion concerning thermal and psychological (psychogenic) seating is tha the former is cholinergically mediated (Dale & Feldberg, 1934), while the latter is of noradrenergic origin (Robertshaw, 1977). Moreover, psychological sweating is thought to be elicited by a different neural centre (Ogawa, 1975), possibly through separate pathways (Chalmers & Keele, 1952) that exclusively innervate the glabrous (non-hairy) skin of the hands and feet (Darow, 1937, Kuno, 1956, Ogawa, 1975). Evidence for the cholinergic modulation of thermal sweating is incontrovertible. However, evidence supporting the theoretical control of psychological sweating is less than convincing. Following observations of …

'As Long As You Have Some Of That, It Cancels It Out': How Advertisers Use Guilt To Sell Us Quick-Fixes For Our Unhealthy Behaviour, Lance Barrie, Sandra C. Jones

Faculty of Health and Behavioural Sciences - Papers (Archive)

In a society with numerous guidelines for „healthy living‟, people make conscious decisions to substitute or trade certain health behaviours with others. The current study investigates young adults‟ perceptions of messages in advertising which imply that use or consumption of a product may have health benefits or may even provide a „solution‟ or trade-off for a consumer who has made (or would like to make) a suboptimal health behaviour choice. Using focus groups and a survey, we found that these types of decisions are common, and that people spontaneously recall editorial and advertising messages that convey such messages. Responding to …

Saving Lives Or Raising Revenue: Analysing Media Coverage Of The Alcopops Tax In Light Of The Evidence On Its Effects, Sandra C. Jones, Laura Robinson Jan 2011

Saving Lives Or Raising Revenue: Analysing Media Coverage Of The Alcopops Tax In Light Of The Evidence On Its Effects, Sandra C. Jones, Laura Robinson

Faculty of Health and Behavioural Sciences - Papers (Archive)

The Australian Government increased the tax on ready-to-drink (RTD) alcohol beverages in 2008, in order to address concerns about increasing alcohol consumption among young people. This decision resulted in significant debate and discussion in the media, and in academic circles. The aim of the current study was to examine media coverage of the debate – and particularly the arguments posed in favour of and against the tax – now that we have objective evidence of its impact. We find that business owners and industry groups were vocal in the media, raising a number of arguments in opposition to the tax; …

Cannabis And Cognition: Short- And Long-Term Effects, Nadia Solowij, Nicole Pesa Jan 2011

Cannabis And Cognition: Short- And Long-Term Effects, Nadia Solowij, Nicole Pesa

Faculty of Health and Behavioural Sciences - Papers (Archive)

Twenty years ago cannabis was generally perceived to be a benign drug with few significant adverse effects. As outlined elsewhere in this book, evidence has since mounted in the scientific literature for a range of harms associated with the use of cannabis, including the development of dependence and health-related harms (see also Hall and Solowij, 1998; Hall and Degenhardt, 2009). As the overall theme of this book indicates, an association between cannabis use and the development of psychotic symptoms or overt psychosis has grown to be recognized as a significant potential harm, and investigating the mechanisms by which cannabis may …

The Spatial Tuning Of "Motion Streak" Mechanisms Revealed By Masking And Adaptation, Deborah Apthorp, John Cass, David Alais Jan 2011

The Spatial Tuning Of "Motion Streak" Mechanisms Revealed By Masking And Adaptation, Deborah Apthorp, John Cass, David Alais

Faculty of Health and Behavioural Sciences - Papers (Archive)

We previously reported that fast-moving dot arrays cause orientation-tuned masking of static gratings (D. Apthorp, J. Cass, & D. Alais, 2010), which we attribute to “motion streaks.” Using similar “streaky” dot motion, we describe spatial frequency tuning of grating threshold elevations caused by masking (Experiment 1) and adaptation (Experiment 2) to motion. To compare the streaks with psychophysical tunings, we Fourier analyzed time-averaged translating dots, which were bandpass (peaking at È2.3 c/deg). Masking, however, was strongest at lower test frequencies (e1 c/deg) and largely isotropic over orientation, although a small orientation-tuned effect occurred at È1.2 c/deg. Results were broadly similar …

Faculty of Health and Behavioural Sciences - Papers (Archive)

An Australian food composition database, AUSNUT1999, does not include long chain omega-3 polyunsaturated fatty acid (LC omega-3 PUFA) data. Measurement of the fatty acid content of diets initially analysed using AUSNUT1999 requires conversion to AUSNUT2007, an updated database inclusive of LC omega-3 PUFA. The aim of this study was to convert clinical trial dietary data from AUSNUT1999 to AUSNUT2007 and measure LC omega-3 PUFA intake. Clinical trial diet history (DH) data was converted from AUSNUT1999 to 2007 using a staged approach. Macronutrient intake from AUSNUT1999 and 2007 were calculated and compared via paired t-tests and Wilcoxon Signed Ranks tests. Mean …

Implementation Of A Major In Mental Health Nursing In Australian Universities, Brenda Happell, Lorna Moxham, Karen-Ann Clarke

Faculty of Health and Behavioural Sciences - Papers (Archive)

The difficulty recruiting and retaining an adequate mental health nursing workforce is acknowledged. The major in mental health nursing has been identified as a strategy to promote this specialist area of practice as desirable for students’ future careers. Measuring its success requires the collection of detailed data about the structure, content, and uptake of these programmes. A survey was specifically developed to elicit descriptive information about the structure and content of a major in mental health nursing programmes. Fourteen universities participated in this research. Eight had implemented a major, one intends to do so in 2011, and five had abandoned …

Depth Interval Estimates From Motion Parallax And Binocular Disparity Beyond Interaction Space, Barbara Gillam, Stephen Palmisano, Donovan Govan Jan 2011

Depth Interval Estimates From Motion Parallax And Binocular Disparity Beyond Interaction Space, Barbara Gillam, Stephen Palmisano, Donovan Govan

Faculty of Health and Behavioural Sciences - Papers (Archive)

Static and dynamic observers provided binocular and monocular estimates of the depths between real objects lying well beyond interaction space. On each trial, pairs of LEDs were presented inside a dark railway tunnel. The nearest LED was always 40 m from the observer, with the depth separation between LED pairs ranging from 0 up to 248 m. Dynamic binocular viewing was found to produce the greatest (ie most veridical) estimates of depth magnitude, followed next by static binocular viewing, and then by dynamic monocular viewing. (No significant depth was seen with static monocular viewing.) We found evidence that both binocular …

Asthma And Ageing: An End User's Perspective- The Perception And Problems With The Management Of Asthma In The Elderly, Sandra C. Jones, Don Iverson, Pippa Burns, Uwana Evers, Peter Caputi, S. Morgan

Faculty of Health and Behavioural Sciences - Papers (Archive)

Despite the high prevalence of asthma in the elderly, its development, diagnosis, and treatment are under-researched. This paper provides a comprehensive review of the current state of knowledge in relation to management of asthma in the elderly – focusing on barriers to diagnosis and treatment and the central role of self-management. Asthma prevalence increases with age, as does the risk of dying from asthma, and with the ageing of the population and increasing life expectancy, the prevalence of (diagnosed and undiagnosed) asthma in older adults is expected to increase drastically, placing an increasing burden on sufferers, the community and health …

Vection In Depth During Consistent And Inconsistent Multisensory Stimulation, April Ash, Stephen Palmisano, Juno Kim

Faculty of Health and Behavioural Sciences - Papers (Archive)

We examined vection induced during physical or simulated head oscillation along either the horizontal or depth axis. In the first two experiments, during active conditions, subjects viewed radial-flow displays which simulated viewpoint oscillation that was either in-phase or out-of-phase with their own tracked head movements. In passive conditions, stationary subjects viewed playbacks of displays generated in earlier active conditions. A third control, experiment was also conducted where physical and simulated fore ^ aft oscillation was added to a lamellar flow display. Consistent with ecology, when active in-phase horizontal oscillation was added to a radial-flow display it modestly improved vection compared …

Reciprocal Signalling Between Nr2 Subunits Of The Nmda Receptor And Neuregulin 1 And Their Role In Schizophrenia, Amy Geddes, Xu-Feng Huang, Kelly A. Newell Jan 2011

Reciprocal Signalling Between Nr2 Subunits Of The Nmda Receptor And Neuregulin 1 And Their Role In Schizophrenia, Amy Geddes, Xu-Feng Huang, Kelly A. Newell

Faculty of Health and Behavioural Sciences - Papers (Archive)

Schizophrenia is a debilitating neurodevelopmental psychiatric disorder. Both the N-methyl-D-aspartate receptor (NMDAR) and neuregulin1 (NRG1) are key molecules involved in normal brain development that have been linked to schizophrenia pathology and aetiology. The NR2 proteins are critical structural and functional subunits of the NMDAR and are developmentally and spatially regulated. Altered NR2 gene and protein expression has been found in human post-mortem schizophrenia brain tissue together with changes in NRG1 and its receptor ErbB4. The NR2 subunits and ErbB4 share a common anchoring domain on the postsynaptic density and therefore a disruption to either of these molecules may influence the …
