Vection Change Exacerbates Simulator Sickness In Virtual Environments, Frederick Bonato, Andrea Bubka, Stephen A. Palmisano, Danielle Phillip, Giselle Moreno Jan 2008

Vection Change Exacerbates Simulator Sickness In Virtual Environments, Frederick Bonato, Andrea Bubka, Stephen A. Palmisano, Danielle Phillip, Giselle Moreno

Faculty of Health and Behavioural Sciences - Papers (Archive)

The optic flow patterns generated by virtual reality (VR) systems typically produce visually induced experiences of self-motion (vection). While this vection can enhance presence in VR, it is often accompanied by a variant of motion sickness called simulator sickness (SS). However, not all vection experiences are the same. In terms of perceived heading and/or speed, visually simulated self-motion can be either steady or changing. It was hypothesized that changing vection would lead to more SS. Participants viewed an optic flow pattern that either steadily expanded or alternately expanded and contracted. In one experiment, SS was measured pretreatment and after 5 …


Effects Of Scenery, Lighting, Glideslope And Experience On Timing The Landing Flare, Stephen A. Palmisano, Simone K. Favelle, W L. Sachtler Jan 2008

Effects Of Scenery, Lighting, Glideslope And Experience On Timing The Landing Flare, Stephen A. Palmisano, Simone K. Favelle, W L. Sachtler

Faculty of Health and Behavioural Sciences - Papers (Archive)

This study examined 3 visual strategies for timing the initiation of the landing flare based on perceptions of either: (i) a critical height above ground level; (ii) a critical runway width angle (Y); or (iii) a critical time-to-contact (TTC) with the runway. Visual displays simulated landing approaches with trial-to-trial variations in glideslope, lighting, and scene detail. Twenty-four participants (8 private pilots, 8 student pilots and 8 non-pilots) were instructed to initiate the flare when they perceived that their TTC with the runway (30 m wide by 840 m long) had reached a critical value of 2 seconds. Our results demonstrated …


Corporate Social Responsibility, Condition Branding And Ethics In Marketing, Danika Hall, Sandra C. Jones Jan 2008

Corporate Social Responsibility, Condition Branding And Ethics In Marketing, Danika Hall, Sandra C. Jones

Faculty of Health and Behavioural Sciences - Papers (Archive)

Over the past two decades there has been increased interest in corporate responsibility (CSR) and its relation to marketing practice and theory )Maignan and Ferrell, 2004: Polonsky and Jevons, 2006). This paper explores another marketing phenomena emerging from the pharmaceutical industry: condition branding (Angelmar, Angelmar and Kane, 2007: Parry, 2003). Condition branding has been positioned as a form of CSR for the industry, in that it provides education to the general public regarding diseases or conditions. However, the ethical nature of condition branding has been questioned as it is also seen as a deliberate method of increasing markets for pharmaceutical …


Communication About Organ Donation Intentions: Formative Research For A Social Marketing Program Targeting Families, Sandra C. Jones, Samantha L. Reis, Kelly L. Andrews Jan 2008

Communication About Organ Donation Intentions: Formative Research For A Social Marketing Program Targeting Families, Sandra C. Jones, Samantha L. Reis, Kelly L. Andrews

Faculty of Health and Behavioural Sciences - Papers (Archive)

With the introduction of the Australian Organ Donation Register (AODR), responsibility regarding organ donation decisions primarily rests with the individual. However, family members can be instrumental in facilitating or hindering the rate of organ donation by objecting to or confirming the individuals wishes. Attitudes and beliefs of family members have been shown to be a strong influence on peoples intentions to donate. Numerous studies have also demonstrated that family communication about organ donation can improve the rate of organ donation. We surveyed 23 matched pairs of undergraduate university students and their parents and found that attitudes to organ donation were …

The Relationship Between Driving Anxiety And Driving Skill: A Review Of Human Factors And Anxiety-Performance Theories To Clarify Future Research Needs, Joanne Taylor, Frank P. Deane, John Podd

Faculty of Health and Behavioural Sciences - Papers (Archive)

This article examines theory and identifies gaps in research related to the role of driving skills in driving anxiety. Increasingly, investigators have examined the clinical features of driving anxiety and the more severe situation of driving fear and phobia, but the possible involvement of driving skills has been neglected. This is surprising given the potential implications for skills training and remediation in the assessment and treatment of some of those who experience driving anxiety, fear, and phobia. The largest body of relevant research comes from the driving and human factors literature on the relationship between anxiety and driving performance. The …

Fish Oil Reduces Heart Rate And Oxygen Consumption During Exercise, Gregory E. Peoples, Peter L. Mclennan, Peter R. C Howe, Herbert Groeller

Faculty of Health and Behavioural Sciences - Papers (Archive)

Dietary omega-3 polyunsaturated fatty acids (PUFAs) are readily incorporated into heart and skeletal muscle membranes where, in the heart, animal studies show they reduce O2 consumption. To test the hypothesis that omega-3 PUFAs alter O2 efficiency in humans, the effects of fish oil (FO) supplementation on O2 consumption during exercise were evaluated. Sixteen well-trained men (cyclists), randomly assigned to receive 8 x 1 g capsules per day of olive oil (control) or FO for 8 weeks in a double-blind, parallel design, completed the study (control: n = 7, age 27.1 +/- 2.7 years; FO: n = 9, age 23.2 +/- …

Self-Reported Neurological Symptoms In Relation To Co Emissions Due To Problem Gas Appliance Installations In London: A Cross-Sectional Survey, Irene Kreis, Giovanni Leonardi, Ben Croxford

Faculty of Health and Behavioural Sciences - Papers (Archive)

Background: Previous research by the authors found evidence that up to 10% of particular household categories may be exposed to elevated carbon monoxide (CO) concentrations from poor quality gas appliance installations. The literature suggests certain neurological symptoms are linked to exposure to low levels of CO. This paper addresses the hypothesis that certain selfreported neurological symptoms experienced by a householder are linked to an estimate of their CO exposure.Methods: Between 27 April and 27 June 2006, 597 homes with a mains supply of natural gas were surveyed, mainly in old, urban areas of London. Qualified gas engineers tested all gas …

Toward The Science-Informed Practice Of Clinical Supervision: The Australian Context, Craig J. Gonsalvez, Hamish Mcleod

Faculty of Health and Behavioural Sciences - Papers (Archive)

Although supervision of clinical practice is mandatory for trainee psychologists, surprisingly little is known about the key ingredients of effective supervision and the relationship between supervision and patient outcomes. The purpose of this paper was to review current regulations that shape supervision in Australia and explore the links between these regulations and the components of effective supervision. Although recent developments including supervisor training and other quality control programs are an indication of progress, there are several empirical and conceptual issues in the supervision literature that require resolution. The second part of this paper identifies the gaps in the supervision literature …

Are Pre-Adolescent Girls' Magazines Providing Age-Appropriate Role Models?, Belinda S. Fabrianesi, Sandra C. Jones, Amanda Reid

Faculty of Health and Behavioural Sciences - Papers (Archive)

Purpose – Repeated exposure to unrealistic notions of female beauty and body shapes, and limited gender stereotypes, may result in the internalization of those standards by pre-adolescent girls. The purpose of this content analysis is to examine the celebrity role models to whom young girls are exposed via magazines specifically targeted at the “tween” audience. Female celebrities are contrasted with those in magazines targeted at older adolescent girls. Design/methodology/approach – Two pre-adolescent girls’ magazines, Total Girl and Barbie, and two adolescent girls’ magazines, Dolly and Girlfriend, were analyzed for the first six months of 2005. All photos (including advertising images) …


Psychologists' Cognitive And Emotional Responses To Working With Borderline Personality Disorder Clients, Marianne E. Bourke, Brin F. Grenyer Jan 2008

Psychologists' Cognitive And Emotional Responses To Working With Borderline Personality Disorder Clients, Marianne E. Bourke, Brin F. Grenyer

Faculty of Health and Behavioural Sciences - Papers (Archive)

Borderline Personality Disorder (BPD) is commonly recognised throughout theoretical and clinical accounts as one of the most challenging mental health disorders to treat however; there has been limited empirical investigation into characteristic psychologists reactions evoked by this diagnostic group. The aim of this study was to investigate cognitive and emotional responses of psychologists treating BPD. Method: Psychologists currently working with BPD clients gave informed consent to be interviewed regarding their responses to this client group. In addition, the Impact Message Inventory (IMI-C) and the Psychotherapy Relationship Questionnaire (PRQ) were completed. Transcripts from a semi-structured interview of psychologist's countertransference experiences were …


Preschool Children's Counterfactual Inferences: The Causal Length Effect Revisited, Amy Y. Chan, Jessica C. Scott Jan 2008

Preschool Children's Counterfactual Inferences: The Causal Length Effect Revisited, Amy Y. Chan, Jessica C. Scott

Faculty of Health and Behavioural Sciences - Papers (Archive)

Research into young childrens counterfactual thinking is equivocal about how childrens counterfactual responses to causal events may be affected by the length of the causal inference required. This study examined the causal length effect in 3- and 4-year-old children (N=87). Children participated in two counterfactual inference tasks involving causally-related sequences of events. One task entailed counterfactual emotional judgements about the experience of characters in stories, whereas the other task entailed a counterfactual inference about a potential alternative outcome to a physical event. Children at each age level were randomly assigned to answer test questions that required a long, medium, or …


Isokinetic Dynamometry In Anterior Cruciate Ligament Injury And Reconstruction, Yong-Hao Pua, Adam Bryant, Julie R. Steele, Robert Newton, Tim Wrigley Jan 2008

Isokinetic Dynamometry In Anterior Cruciate Ligament Injury And Reconstruction, Yong-Hao Pua, Adam Bryant, Julie R. Steele, Robert Newton, Tim Wrigley

Faculty of Health and Behavioural Sciences - Papers (Archive)

The use of Isokinetic dynamometry has often been criticised based on the face-validity argument that isokinetic movements poorly resemble the everyday multi-segmented, dynamic activities of human movements. In the anterior cruciate ligament (ACL) reconstruction or defiency population where muscle deficits are ubiquitous, this review paper has made a case for using isokinetic dynamometry to isolate and quantify these deficits in a safe and controlled manner.

Polysaccharopeptide Enhances The Anticancer Activity Of Doxorubicin And Etoposide On Human Breast Cancer Cells Zr-75-30, Jennifer Man-Fan Wan, Wai Hung Sit, Jimmy Chun Yu Louie

Faculty of Health and Behavioural Sciences - Papers (Archive)

In search of natural bioactive microbial compounds with adjuvant properties, we have previously showed that the polysaccharopeptide (PSP), isolated from Chinese medicinal mushroom Coriolus versicolor, was able to enhance the cytotoxicity of certain S-phase targeted-drugs on human leukemic HL-60 cells via some cell-cycle and apoptotic-dependent pathways. The present study aimed to investigate whether the synergism of mechanisms of PSP with certain chemotherapeutic drugs also applies to human breast cancer. PSP treatment enhanced the cytotoxicity of doxorubicin (Doxo), etoposide (VP-16) but not cytarabine (Ara-C). Bivariate bromodeoxyuridine (BrdUrd)/DNA flow cytometry analysis estimated a longer DNA synthesis time (Ts) for the PSP treated …

Electrospray ionisation tandem mass spectrometry has allowed the unambiguous identification andquantification of individual lens phospholipids in human and six animal models. Using this approach ca. 100unique phospholipids have been characterised. Parallel analysis of the same lens extracts by a novel directinsertionelectron-ionization technique found the cholesterol content of human lenses to be significantlyhigher (ca. 6 times) than lenses from the other animals.The most abundant phospholipids in all the lenses examined were choline-containing phospholipids. In rat,mouse, sheep, cow, pig and chicken, thesewere present largely as phosphatidylcholines, in contrast 66% of thetotal phospholipid in Homo sapienswas sphingomyelin, with the most abundant being dihydrosphingomyelins,in …


Expanding And Contracting Optic-Flow Patterns And Vection, Andrea Bubka, Frederick Bonato, Stephen A. Palmisano Jan 2008

Expanding And Contracting Optic-Flow Patterns And Vection, Andrea Bubka, Frederick Bonato, Stephen A. Palmisano

Faculty of Health and Behavioural Sciences - Papers (Archive)

When stationary observers view an optic-flow pattern, visually induced self-motion perception (vection) and a form of motion sickness known as simulator sickness (SS), can result. Previous results suggest that an expanding flow pattern leads to more SS than a contracting pattern. Sensory conflict, a possible cause of SS, may be more salient when an expanding optic-flow pattern is viewed. An experiment was conducted to test if a more salient sensory conflict accompanying expanding flow patterns might inhibit vection. Participants (n=15) viewed a pattern of blue squares, either steadily expanded or contracted, on a large rear-projection screen. Vection onset and magnitude …


Amplified Voices, But They Are Speaking To The Wrong People. Why The Complaint System For Unacceptable Advertising In Australia Is Not Working, Katherine Eagleton, Sandra C. Jones Jan 2008

Amplified Voices, But They Are Speaking To The Wrong People. Why The Complaint System For Unacceptable Advertising In Australia Is Not Working, Katherine Eagleton, Sandra C. Jones

Faculty of Health and Behavioural Sciences - Papers (Archive)

This exploratory study highlights the lack of public awareness of the role of the Advertising Standards Board (ASB) in the process of handling complaints about unacceptable advertising in Australia. Results show that only a small proportion of Australian adults know that the ASB are the appropriate complaints handling body. This lack of awareness is evident even among those who have made a complaint about advertising (generally to a less appropriate body). This highlights the need for an education campaign to inform the general public how to make a complaint about inappropriate advertising, and who to make a complaint to. Empowering …


Accelerating Self-Motion Displays Produce More Compelling Vection In Depth, Stephen A. Palmisano, Robert S Allison, Fiona Pekin Jan 2008

Accelerating Self-Motion Displays Produce More Compelling Vection In Depth, Stephen A. Palmisano, Robert S Allison, Fiona Pekin

Faculty of Health and Behavioural Sciences - Papers (Archive)

We examined the vection in depth induced when simulated random self-accelerations (jitter) and periodic self-accelerations (oscillation) were added to radial expanding optic flow (simulating constant-velocity forward self-motion). Contrary to the predictions of sensory-conflict theory frontal-plane jitter and oscillation were both found to significantly decrease the onsets and increase the speeds of vection in depth. Depth jitter and oscillation had lesser, but still significant, effects on the speed of vection in depth. A control experiment demonstrated that adding global perspective motion which simulated a constant-velocity frontal-plane self-motion had no significant effect on vection in depth induced by the radial component of …

The Effect Of Counterfactual Priming On Women's Decisions Regarding Mammography Screening, Amy Y. Chan, Jing Wang, Peter Caputi

Faculty of Health and Behavioural Sciences - Papers (Archive)

The counterfactual priming effect occurs when "what if" and "if only" thoughts about one event broadens ones mind-set to consider a more diverse range of evidence and possibilities in a different decision making or problem solving context. This study examined this effect as applied to mammography screening decisions.


Fpga Implementation Of A Predictive Vector Quantization Image Compression Algorithm For Image Sensor Applications, Yan Wang, Amine Bermak, Abdesselam Bouzerdoum, Brian W. Ng Jan 2008

Fpga Implementation Of A Predictive Vector Quantization Image Compression Algorithm For Image Sensor Applications, Yan Wang, Amine Bermak, Abdesselam Bouzerdoum, Brian W. Ng

Faculty of Health and Behavioural Sciences - Papers (Archive)

This paper presents a hybrid image compression scheme based on a block based compression algorithm referred to as Vector Quantization (VQ) combined with the Differential Pulse Code Modulation (DPCM) technique. The proposed image compression technique called the PVQ scheme results in enhanced image quality as compared to the standalone VQ. The generated codebooks for the PVQ scheme are more robust for image coding than that of the VQ. This made our system a suitable candidate for developing on chip image sensor with integrated data compression processor. The proposed system was validated through FPGA implementation. The resulting implementation achieved good compression …
