Consistency Of Supervisor And Peer Ratings Of Assessment Interviews Conducted By Psychology Trainees, Craig J. Gonsalvez, Frank P. Deane, Peter Caputi Jan 2016

Consistency Of Supervisor And Peer Ratings Of Assessment Interviews Conducted By Psychology Trainees, Craig J. Gonsalvez, Frank P. Deane, Peter Caputi

Faculty of Social Sciences - Papers (Archive)

Observation of counsellor skills through a one-way mirror, video or audio recording followed by supervisors and peers feedback is common in counsellor training. The nature and extent of agreement between supervisor-peer dyads is unclear. Using a standard scale, supervisors and peers rated 32 interviews by psychology trainees observed through a one-way mirror. Results indicated that peers and supervisors used similar dimensions to cluster the various competencies. Peers rated counsellor performance more positively for general counselling skills but not for specialised techniques. Analyses revealed good supervisor-peer agreement for some items and poor agreement on others, with some differences being unacceptably large. …

Pulse Modulated Radiofrequency Exposure Influences Cognitive Performance, Adam Verrender, Sarah P. Loughran, Anna Dalecki, Raymond J. Mckenzie, Rodney J. Croft Jan 2016

Pulse Modulated Radiofrequency Exposure Influences Cognitive Performance, Adam Verrender, Sarah P. Loughran, Anna Dalecki, Raymond J. Mckenzie, Rodney J. Croft

Faculty of Social Sciences - Papers (Archive)

Purpose: To investigate whether exposure to pulse modulated radiofrequency (PM RF) influences human cognitive performance, and whether it does so in a dose-dependent manner. Materials and methods: Thirty-six healthy adults participated in a randomized, double-blind, counterbalanced provocation study. Cognitive performance was assessed using a visual discrimination task and a modified Sternberg working memory task, which were calibrated to individual performance levels in a preliminary testing session. An sXh920 planar exposure system was used to generate a 920 MHz GSM-like signal, providing three conditions (peak-spatial SAR averaged over 10 g) of 0 W/kg (sham), 1 W/kg (low RF) and …

Background Gross motor competence confers health benefits, but levels in children and adolescents are low. While interventions can improve gross motor competence, it remains unclear which correlates should be targeted to ensure interventions are most effective, and for whom targeted and tailored interventions should be developed. Objective The aim of this systematic review was to identify the potential correlates of gross motor competence in typically developing children and adolescents (aged 3–18 years) using an ecological approach. Methods Motor competence was defined as gross motor skill competency, encompassing fundamental movement skills and motor coordination, but excluding motor fitness. Studies needed to …

The Impact Of Marketing And Advertising On Food Behaviours: Evaluating The Evidence For A Causal Relationship, Jennifer A. Norman, Bridget Kelly, Emma J. Boyland, Anne T. Mcmahon

Faculty of Social Sciences - Papers (Archive)

The prevention of overweight in childhood is paramount to long-term heart health. Food marketing predominately promotes unhealthy products which, if over-consumed, will lead to overweight. International health expert calls for further restriction of children¿s exposure to food marketing remain relatively unheeded, with a lack of evidence showing a causal link between food marketing and children¿s dietary behaviours and obesity an oft-cited reason for this policy inertia. This direct link is difficult to measure and quantify with a multiplicity of determinants contributing to dietary intake and the development of overweight. The Bradford Hill Criteria provide a credible framework by which epidemiological …

The Paradox Of Engagement: Land Stewardship And Invasive Weeds In Amenity Landscapes, Peter Klepeis, Nicholas J. Gill Jan 2016

The Paradox Of Engagement: Land Stewardship And Invasive Weeds In Amenity Landscapes, Peter Klepeis, Nicholas J. Gill

Faculty of Social Sciences - Papers (Archive)

In New South Wales, Australia, rural landscapes are undergoing profound change as a result of exurbanization. Newcomers-amenity migrants-are drawn to the scenic beaches, forests, and open landscape character of this part of Australia near Sydney and they join existing communities of long-term residents, notably ranchers involved in dairy, beef, and other types of primary agricultural production. The rural to exurban transition is stimulating both intended and unintended socio-ecological changes, especially the proliferation of invasive weeds, which are considered to be a top national priority as they threaten Australia's agricultural economy. Drawing on interview and survey research from three case studies …

A Systematic Review Of The Relationship Between Psychological Disorders Or Substance Use And Self-Reported Cognitive Failures, Nicole Carrigan, Emma Barkus

Faculty of Social Sciences - Papers (Archive)

Cognitive failures are errors in normal everyday functioning. Individuals with psychological disorders may possess heightened vulnerability. We sought to review the literature on cognitive failures in psychological disorders to determine the nature of this association, and whether failures relate to neuropsychological performance. We also examine the relationship between cognitive failures and substance use since it is relevant to everyday cognition and co-occurs in many psychological disorders. Methods: We conducted a systematic review of self-reported cognitive failures in psychological disorders and substance use, identifying 21 papers in total. Results: Papers identified studied trauma, mood, and anxiety disorders, and schizophrenia. Substance use …

Social Practices Of 3d Printing: Decentralising Control And Reconfiguring Regulation, Luke Heemsbergen, Robbie Fordyce, Bjorn Nansen, Thomas Apperley, Michael Arnold, Thomas Birtchnell Jan 2016

Social Practices Of 3d Printing: Decentralising Control And Reconfiguring Regulation, Luke Heemsbergen, Robbie Fordyce, Bjorn Nansen, Thomas Apperley, Michael Arnold, Thomas Birtchnell

Faculty of Social Sciences - Papers (Archive)

This paper considers the social practices of 3D printing by comparing consumer perspectives and practices with legal scholarship on intellectual property regimes. The paper draws on data gained through a mixed-methods approach involving participant observation, focus groups, and social network analysis of 3D printing file-sharing practices. It finds that while consumers display a level of naivety about their 3D printing rights and responsibilities, they possess a latent understanding about broader digital economies that guide their practices. We suggest that the social practices associated with 3D printing function through communication networks to decentralise manufacture and reconfigure legal capacities for regulation. The …

Nutrition Education In Australian Midwifery Programmes: A Mixed-Methods Study, Jamila Arrish, Heather Yeatman, Moira J. Williamson Jan 2016

Nutrition Education In Australian Midwifery Programmes: A Mixed-Methods Study, Jamila Arrish, Heather Yeatman, Moira J. Williamson

Faculty of Social Sciences - Papers (Archive)

Little research has explored how nutrition content in midwifery education prepares midwives to provide prenatal nutrition advice. This study examined the nature and extent of nutrition education provided in Australian midwifery programmes. A mixed-methods approach was used, incorporating an online survey and telephone interviews. The survey analysis included 23 course coordinators representing 24 of 50 accredited midwifery programmes in 2012. Overall, the coordinators considered nutrition in midwifery curricula and the midwife's role as important. All programmes included nutrition content; however, eleven had only 5 to nutrition, while two had a designated unit. Various topics were covered. Dietitians/other nutrition experts were …

Mobilities And The Multinatural: A Test Case In India, Thomas Birtchnell Jan 2016

Mobilities And The Multinatural: A Test Case In India, Thomas Birtchnell

Faculty of Social Sciences - Papers (Archive)

This article examines whether the mobilities paradigm could be more sensitive to recent debates about the more-than-human (animals, plants, and insects) and indeed the inhuman (geological, planetary, and biophysical). Many possible examples spring to mind: the forced movement of people due to "natural" catastrophes, the annual migrations of birds across vast distances, the accidental and intentional spread of invasive weeds. "Multinatural mobilities" are at present both inside and outside of the paradigm's core themes. Can mobilities go beyond transportation, migration, urban development, the hypermobility of the few, and the comparative immobility of the world's majority of people to encompass everything …

Gifted Education In Modern Asia: Analyses From A Systemic Perspective, Wilma Vialle, Albert Ziegler Jan 2016

Gifted Education In Modern Asia: Analyses From A Systemic Perspective, Wilma Vialle, Albert Ziegler

Faculty of Social Sciences - Papers (Archive)

When we were invited to comment on chapters describing gifted educa· tion in Asian countries, we were reminded of Mikhail Gorbachev's famous dictum "Life punishes those who delay." Asian countries entered gifted education and research on excellence relatively late compared to many Western nations (e.g., Stern, 1914). Nevertheless, there are examples that suggest the opposite may be true, that is, latecomers might also have some advantage. A famous example for the latter claim is the case of the Golden Gate Bridge and the Akashi Kaikyo Bridge. Both are suspension bridges linking the U.S. city of San Francisco to Marin County …

A Cluster-Randomised Controlled Trial Of Values-Based Training To Promote Autonomously Held Recovery Values In Mental Health Workers, Virginia Williams, Frank P. Deane, Lindsay G. Oades, Trevor P. Crowe, Joseph Ciarrochi, Retta Andresen

Faculty of Social Sciences - Papers (Archive)

Background The implementation and use of evidence-based practices is a key priority for recovery-oriented mental health service provision. Training and development programmes for employees continue to be a key method of knowledge and skill development, despite acknowledged difficulties with uptake and maintenance of behaviour change. Self-determination theory suggests that autonomy, or a sense that behaviour is self-generated, is a key motivator to sustained behaviour change, in this case practices in mental health services. This study examined the utility of values-focused staff intervention as a specific, reproducible method of autonomy support. Methods Mental health workers (n = 146) were assigned via …

This research investigated the utility and practicality of dependency grids for capturing and presenting the dependency distribution patterns of three adolescents with autism spectrum disorder. The investigation also involved family members to explore their level of awareness of the adolescents' dependency preferences. The grids were analyzed using a range of measures, including the uncertainty index and partial order scalogram analysis. Findings indicate the adolescents had various ways of dispersing their dependencies among their resources and differed in the types of support most used. Additionally, family members differed in their awareness of the adolescents' preferences. The benefits and drawbacks of the …

The Role Of Cannabinoids In Neuroanatomic Alterations In Cannabis Users, Valentina Lorenzetti, Nadia Solowij, Murat Yuecel Jan 2016

The Role Of Cannabinoids In Neuroanatomic Alterations In Cannabis Users, Valentina Lorenzetti, Nadia Solowij, Murat Yuecel

Faculty of Social Sciences - Papers (Archive)

The past few decades have seen a marked change in the composition of commonly smoked cannabis. These changes primarily involve an increase of the psychoactive compound Delta(9)-tetrahydrocannabinol (THC) and a decrease of the potentially therapeutic compound cannabidiol (CBD). This altered composition of cannabis may be linked to persistent neuroanatomic alterations typically seen in regular cannabis users. In this review, we summarize recent findings from human structural neuroimaging investigations. We examine whether neuroanatomic alterations are 1) consistently observed in samples of regular cannabis users, particularly in cannabinoid receptor-high areas, which are vulnerable to the effects of high circulating levels of THC, …

Shifting The Blame In Higher Education - Social Inclusion And Deficit Discourses, Sarah Elizabeth O'Shea, Pauline Lysaght, Jen Roberts, Valerie Harwood Jan 2016

Shifting The Blame In Higher Education - Social Inclusion And Deficit Discourses, Sarah Elizabeth O'Shea, Pauline Lysaght, Jen Roberts, Valerie Harwood

Faculty of Social Sciences - Papers (Archive)

The principles of social inclusion have been embraced by institutions across the higher education sector but their translation into practice through pedagogy is not readily apparent. This paper examines perceptions of social inclusion and inclusive pedagogies held by academic staff at an Australian university. Of specific interest were the perceptions of teaching staff with regard to diverse student populations, particularly students from low socio-economic (LSES) backgrounds, given the institution's reasonably high proportion of LSES student enrolment (14%). A mixed-method approach was utilised: (i) in-depth interviews with a representative sample of academic staff and (ii) an online survey targeting all academic …

Internationally, childhood obesity is a major public health concern. Given the established difficulties in treating obesity, designing and evaluating effective obesity prevention interventions are research priorities. As parents play a crucial role in establishing positive health behaviours in children, they are a key target for child obesity prevention programs. However, recruiting and engaging parents in such interventions can be a considerable challenge for researchers and practitioners. Members of the 'Parenting, Child Behaviour and Well-being' stream of the Australasian Child and Adolescent Obesity Research Network (ACAORN) have considerable and varied expertise in conducting such interventions and can provide insights into addressing …

Perceptions Of Consent In Adult Male Rape: Evidence-Based And Inclusive Policy Making, Natalia K. Hanley, Philip Rumney Jan 2016

Perceptions Of Consent In Adult Male Rape: Evidence-Based And Inclusive Policy Making, Natalia K. Hanley, Philip Rumney

Faculty of Social Sciences - Papers (Archive)

Interest in evidence-based policy making in the UK and elsewhere has been documented over many years. There has also been much attention given to the issue of sexual violence from policy makers. Virtually all of this attention has been gendered in the sense that it has focused on female victims and male perpetrators. Given the gendered nature of rape, this is hardly surprising; however, to say that sexual violence and victimisation is a gendered phenomenon is not to suggest that males are invulnerable to sexual violation. Indeed, the empirical data makes clear that 'each and every body is permeable and …

A Comparison Of Chinese And Australian University Students' Attitudes Towards Plagiarism, John Ehrich, Steven J. Howard, Congjun Mu, Sahar Bokosmaty

Faculty of Social Sciences - Papers (Archive)

Student plagiarism is a growing problem within Australian universities and abroad. Potentially exacerbating this situation, research indicates that students' attitudes toward plagiarism are typically more permissive and lenient than the policies of their tertiary institutions. There has been suggestion that this is especially so in Asian countries relative to Western countries; however, very little research has sought to empirically validate this suggestion. Moreover, existing research in this area has typically compared international and domestic students studying in Western countries. As yet, no studies have directly compared Chinese and Australian university students' attitudes toward plagiarism, as they exist within their native …

Constrained Ordination Analysis With Enrichment Of Bell-Shaped Response Functions, Yingjie Zhang, Olivier Thas Jan 2016

Constrained Ordination Analysis With Enrichment Of Bell-Shaped Response Functions, Yingjie Zhang, Olivier Thas

Faculty of Engineering and Information Sciences - Papers: Part A

Constrained ordination methods aims at finding an environmental gradient along which the species abundances are maximally separated. The species response functions, which describe the expected abundance as a function of the environmental score, are according to the ecological fundamental niche theory only meaningful if they are bell-shaped. Many classical model-based ordination methods, however, use quadratic regression models without imposing the bell-shape and thus allowing for meaningless U-shaped response functions. The analysis output (e.g. a biplot) may therefore be potentially misleading and the conclusions are prone to errors. In this paper we presenta log-likelihood ratio criterion with a penalisation term to …

The Effect Of Respiratory Induced Density Variations On Non-Tof Pet Quantitation In The Lung, Beverley F. Holman, Vesna Cuplov, Brian F. Hutton, Ashley M. Groves, Kris Thielemans Jan 2016

The Effect Of Respiratory Induced Density Variations On Non-Tof Pet Quantitation In The Lung, Beverley F. Holman, Vesna Cuplov, Brian F. Hutton, Ashley M. Groves, Kris Thielemans

Faculty of Engineering and Information Sciences - Papers: Part A

Accurate PET quantitation requires a matched attenuation map. Obtaining matched CT attenuation maps in the thorax is difficult due to the respiratory cycle which causes both motion and density changes. Unlike with motion, little attention has been given to the effects of density changes in the lung on PET quantitation. This work aims to explore the extent of the errors caused by pulmonary density attenuation map mismatch on dynamic and static parameter estimates. Dynamic XCAT phantoms were utilised using clinically relevant 18F-FDG and 18F-FMISO time activity curves for all organs within the thorax to estimate the expected parameter errors. The …

Planogram Compliance Checking Based On Detection Of Recurring Patterns, Song Liu, Wanqing Li, Stephen J. Davis, Christian H. Ritz, Hongda Tian Jan 2016

Planogram Compliance Checking Based On Detection Of Recurring Patterns, Song Liu, Wanqing Li, Stephen J. Davis, Christian H. Ritz, Hongda Tian

Faculty of Engineering and Information Sciences - Papers: Part A

In this article, the authors propose a novel method for automatic planogram compliance checking in retail chains that doesn't require product template images for training. Product layout is extracted from an input image by means of unsupervised recurring pattern detection and matched via graph matching, with the expected product layout specified by a planogram to measure the level of compliance. A divide-and-conquer strategy is employed to improve the speed. Specifically, the input image is divided into several regions based on the planogram. Recurring patterns are detected in each region, respectively, and then merged together to estimate the product layout.
