Occupational Respiratory Health Surveillance At Minara Resources, Murrin Murrin Mine Site [Journal Article], Martyn Cross, Jacques Oosthuizen

Research outputs 2013

A respiratory health study of fly-in-fly-out workers potentially exposed to airborne contaminants, and a control group, was conducted at the Murrin Murrin mine site in Western Australia. Lung function was measured in terms of validated protocols (American Thoracic Society, 1995; Miller et al, 2005). The effect of length of service, as well as work area/department on lung function was established. Repeat lung function tests were conducted after approximately two years, in order to measure decrements over time. Furthermore, testing was conducted on a cohort of refinery workers prior to commencement and upon completion of their work period on-site (swing), in …

Physical Activity: Its Implication On Attention Span And Quality Of Life In Children With Autism Spectrum Disorders, Beron W.Z. Tan, Lynne Cohen, Julie A. Pooley

Research outputs 2013

This study examined the effects of physical activity on the attention span and health-related quality of life (HRQoL) of autism spectrum disorder (ASD) children in Singapore. Male participants (N = 12) aged 2-6 years, diagnosed with ASD were randomly assigned to either a physical activity or non-physical activity group. In the physical activity group, participants were administered 8 tri-cycling sessions; both groups of participants were measured for their attention span, and their parents completed the HRQoL questionnaires. Results indicate that as the exercise increases, the physical activity group demonstrated increasingly longer duration of attention span. These results extend the findings …

Patterns Of Physical And Psychological Development In Future Teenage Mothers, Daniel Nettle, Thomas E. Dickins, David A. Coall, Paul De Monrnay Davis

Research outputs 2013

Background and objectives: Teenage childbearing may have childhood origins and can be viewed as the outcome of a coherent reproductive strategy associated with early environmental conditions. Life-history theory would predict that where futures are uncertain fitness can be maximized through diverting effort from somatic development into reproduction. Even before the childbearing years, future teenage mothers differ from their peers both physically and psychologically, indicating early calibration to key ecological factors. Cohort data have not been deliberately collected to test life-history hypotheses within Western populations. Nonetheless, existing data sets can be used to pursue relevant patterns using socioeconomic variables as indices …

Prediction Models For Solitary Pulmonary Nodules Based On Curvelet Textural Features And Clinical Parameters, Jing-Jing Wang, Hai-Feng Wu, Tao Sun, Xia Li, Wei Wang, Li-Xin Tao, Da Huo, Ping-Xin Lv, Wen He, Xiu-Hua Guo

Research outputs 2013

Lung cancer, one of the leading causes of cancer-related deaths, usually appears as solitary pulmonary nodules (SPNs) which are hard to diagnose using the naked eye. In this paper, curvelet-based textural features and clinical parameters are used with three prediction models [a multilevel model, a least absolute shrinkage and selection operator (LASSO) regression method, and a support vector machine (SVM)] to improve the diagnosis of benign and malignant SPNs. Dimensionality reduction of the original curvelet-based textural features was achieved using principal component analysis. In addition, non-conditional logistical regression was used to find clinical predictors among demographic parameters and morphological features. …

International Perceptions Of Stalking And Responsibility: The Influence Of Prior Relationship And Severity Of Behavior, Adrian J. Scott, Nikki Rajakaruna, Lorraine Sheridan, Emma Sleath

Research outputs 2013

This study investigates the influence of prior relationship and severity of behavior on perceptions of stalking and responsibility with a combined sample of 1,080 members of the community from Australia, the United States, and the United Kingdom. Participants were presented with 1 of 12 versions of a hypothetical stalking scenario and responded to scale items regarding the behavior of a male perpetrator toward a female target. Prior relationship and severity of behavior influenced perceptions of stalking and responsibility, and the pattern of findings was consistent across the three countries. The perpetrator’s behavior was perceived to constitute stalking, and necessitate police …

The Influence Of Prior Relationship On Perceptions Of Stalking: A Comparison Of Laypersons, Nonspecialist Police Officers And Specialist Police Officers, Adrian J. Scott, Keri Nixon, Lorraine Sheridan

Research outputs 2013

The current research examined the influence of prior relationship on perceptions of stalking, and compared the perceptions of laypersons, nonspecialist police officers, and specialist police officers. Two studies employed experimental designs where participants were presented with one of three vignettes in which the nature of the prior relationship was manipulated so that the perpetrator and victim were portrayed as strangers, acquaintances, or ex-partners. Participants comprised 101 nonspecialist police officers and 108 laypersons in Study 1, and 49 specialist police officers and 49 nonspecialist police officers in Study 2. Findings indicate that nonspecialist police officers and laypersons shared the common misperception …

Framing And Perceptions Of Stalking: The Influence Of Conduct Severity And The Perpetrator-Target Relationship, Adrian J. Scott, Nikki Rajakaruna, Lorraine P. Sheridan

Research outputs 2013

Research has demonstrated that the way in which questions are presented (i.e. framed) has the capacity to influence responses to subsequent questions. In the context of stalking, perception research has often been framed in terms of whether or not particular behaviours constitute stalking. The current research investigates whether the framing of the opening question (question frame), conduct severity and the perpetrator target relationship influence perceptions of stalking. Two studies employed experimental 3 3 independent factorial designs: one to examine question frame and conduct severity, the other to examine question frame and the perpetrator target relationship. Participants in both studies (total …

Understanding Perceptions Of Stalking: The Impact Of Additional Contextual Information Regarding The Breakdown Of Relationships, Simon C. Duff, Adrian J. Scott

Research outputs 2013

Purpose: Perception research has demonstrated that people view stranger stalkers to be more persistentand dangerous than ex-partner stalkers. Although these findings are consistent with the outcome of legal processes where stranger stalkers are more likely to be convicted, they contrast with the findings of national surveys and applied research where ex-partner stalkers represent the most persistent and dangerous relational subtype. The aim of the current study is to further examine the influence of prior relationship on perceptions of stalking by considering the impact of additional contextual information regarding the breakdown of ex-partners’ relationships for the first time.

The Attribution Of Responsibility In Cases Of Stalking, Adrian J. Scott, Jeffery Gavin, Emma Sleath, Lorraine Sheridan

Research outputs 2013

There is a general belief that stranger stalkers present the greatest threat to the personal safety of victims, despite national victimisation surveys and applied research demonstrating that ex-partner stalkers are generally more persistent and violent. The just-world hypothesis offers a possible explanation for this apparent contradiction. The current research used nine hypothetical scenarios, administered to 328 university students, to investigate the assumptions that underlie attributions of responsibility in cases of stalking. It explores whether these assumptions are consistent with the proposed mechanisms of the just-world hypothesis, and whether they vary according to the nature of the perpetrator–victim relationship and conduct …

Research outputs 2013

This paper presents the first phase on a study investigating the skills of workers in the resource sector at their safety induction to identify workplace hazards. This study questioned the ability of managers and employees to identify workplace hazards correctly (phase 1) and to determine the processes that can be used to increase hazard identification skills (phase 2). Fifty-four completed surveys that contained 6 pictures displaying complex and hazardous work environments in an underground mine in WA are analysed. The analysis sought to determine the average number of hazards that each participant could identify out of a possible 10 in …

Improving Safety Culture: The Impact Of The Construction Induction Training On The Construction Industry In Western Australia, Susanne T. Bahn, Llandis G. Barratt-Pugh

Research outputs 2013

Australia strives to be a world leader in safety practice however improving safety cultures to reduce work-related injuries in the hazardous environment of the construction industry is a continual challenge. It is particularly difficult in Western Australia (WA) where the industry is engaging with the second development boom this century, often in isolated locations, and simultaneously adapting to the national harmonisation of OHS regulations. In 2006, Worksafe WA introduced mandatory certification in safety awareness training for all employees, before they could begin work on a construction site. This paper reviews the impact of this training on the construction industry, presenting …

The Unmet Promise Of Occupational Health And Safety Harmonisation: Continued Complexity For Small, Multi-Jurisdictional Firms, Susanne T. Bahn, Susan Mayson, Rowena Barrett, Llandis G. Barratt-Pugh

Research outputs 2013

Harmonisation of state-based occupational health and safety (OHS) regimes is a Council of Australian Governments (COAG) initiative designed to ‘cut red tape’ for Australian firms. However Western Australia’s, South Australia’s and Victoria’s lack of harmonisation makes it problematic for firms that conduct business in multiple jurisdictions. In this paper we investigate what impacts harmonisation has on firms generally and specifically smaller, multi-jurisdictional firms. First, we look at the requirements of the model WHS Act and what it said about managerial responsibilities for OHS. We focus on the due diligence clause which places personal liability on company directors or persons conducting …

Harmonisation Of Construction Health And Safety Laws In Australia, Manikam Pillay

Research outputs 2013

For over four decades all states and territories in Australia have maintained their own and separate set of laws for the management of health and safety risks in construction. This resulted in at least ten different sets of health and safety legislation. Responding to calls for national uniformity, a harmonised set of laws wer issued in 2011 by the Federal Government, in the form of Model Work Health and safety Act and Regulations. These, together with industry-specific codes of practice, are expected to provide construction organisations their first ever common set of standards and benchmarks across the states and territories …

Review Of Physical Activity Among Indigenous People, Caitlin A. Gray, Rona Macniven, Neil J. Thomson

Research outputs 2013

Physical activity is important for all Australians, particularly in the prevention, management and treatment of chronic conditions, and for social and emotional wellbeing. Chronic health conditions, including cardiovascular conditions, endocrine conditions (such as diabetes), and certain cancers, account for 70% of the observed difference in the burden of disease between the Indigenous and non-Indigenous populations. Modifiable risk factors, particularly behavioural determinants such as physical activity, can help to reduce the extent and impact of these conditions, and assist in the prevention, management and treatment of disease. The levels and impacts of physical inactivity are greater for Indigenous people than they …

Review Of Kidney Disease Among Indigenous People, Sasha A. Stumpers, Neil J. Thomson

Research outputs 2013

Kidney disease is a significant health problem for all Australians, but severe kidney disease is more common among Indigenous people than among non- Indigenous people. In particular, the prevalence of chronic kidney disease (CKD) and the overall levels of end-stage kidney disease (ESKD) among Aboriginal and Torres Strait Islander peoples are consistently reported as significantly higher than among other Australians. Information on CKD among Indigenous Australians is available from self-reported survey data, as well as from community-based studies and screening programs [10-20] but the main focus in the literature has been on ESKD. The incidence of ESKD is especially high …

Review Of Ear Health And Hearing Among Indigenous Australians, Jane F. Burns, Neil J. Thomson

Research outputs 2013

Indigenous Australians experience some of the highest levels of ear disease and hearing loss in the world, with rates up to ten times more than those for non-Indigenous Australians [4]. Children and adolescents are particularly vulnerable to ear infections. The most common ear disease among Indigenous children is otitis media (OM), which is inflammation/infection of the middle ear typically caused by bacterial and viral pathogens. Indigenous children living in urban, rural and, particularly, remote areas, are more likely than their non-Indigenous counterparts to have OM at younger ages, more often, at a greater level of severity, and with more likelihood …

Pedal Force Effectiveness In Cycling: A Review Of Constraints And Training Effects, Rodrigo Bini, Patria Hume, James L. Croft, Andrew Kilding

Research outputs 2013

Pedal force effectiveness in cycling is usually measured by the ratio of force perpendicular to the crank (effective force) and total force applied to the pedal (resultant force). Most studies measuring pedal forces have been restricted to one leg but a few studies have reported bilateral asymmetry in pedal forces. Pedal force effectiveness is increased at higher power output and reduced at higher pedaling cadences. Changes in saddle position resulted in unclear effects in pedal force effectiveness, while lowering the upper body reduced pedal force effectiveness. Cycling experience and fatigue had unclear effects on pedal force effectiveness. Augmented feedback of …

Perceptions Of Five-Year Competitive Categories: Model Of How Relative Age Influences Competitiveness In Masters Sport, Nikola Medic, Bradley Young, J. Robert Grove

Research outputs 2013

The purpose of this study was to examine the contrasting perceptions of masters swimmers related to the first and fifth constituent years of a 5-year age category. Swimmers aged between 35 and 93 years (154 male, 184 female) were surveyed at the 2008 FINA World Masters Championships. Exploratory factor analysis indicated the existence of the following five factors considered important for preparation, attendance, and success at masters competitions: awareness of advantages, expectancy, motivation, training, and physiological capacity. One sample ttests showed that masters swimmers are conscious of advantages that 5-year age categories afford to relatively-younger cohorts (i.e., those who are …

Technique Adjustments Influence The Performance Of Sprint Paddling In Competitive Male Surfers, Jeremy M. Sheppard, Mark Osborne, Dale W. Chapman, Mark Andrews, Phil Mcnamara

Creating Cultural Empathy And Challenging Attitudes Through Indigenous Narratives, Cobie Rudd, Moira Sim, Colleen Hayward, Toni Wain

Research outputs 2013

The poorer health status of Indigenous Australians has been largely attributed to social disadvantage and their marginalisation within mainstream society (Marmot, 2011). This includes access to health care, as well as proximity to health services, availability and cultural appropriateness of health services, transport availability, health insurance, the affordability of health services and patient proficiency in English (AIHW, 2011).

The interpersonal attitudes and behaviours of non-Indigenous health providers, both conscious and unconscious, are also known to contribute to disparities in treatment, impairment of communication between health providers and patients, and consequently, patients’ mistrust of the health system due to negative past …

Psychological Resilience Of Western Australian Police Officers: Relationship Between Resilience, Coping Style, Psychological Functioning And Demographics, Gemma M. Balmer, Julie Ann Pooley, Lynne Cohen

Research outputs 2013

This study examines the relationships between resilience, coping style, psychological functioning and the demographic variables of gender, age, rank and length of service in a sample of 285 Western Australian Police officers. Regression analysis indicated that resilience was predicted by greater use of rational coping and less use of emotional coping, but not psychological functioning. Increased age, rank and length of service were all correlated with significantly lower resilience scores. Significant differences in coping styles were found for all demographic variables. Implications of these findings and recommendations for future research are discussed.
