The aim of this study is to investigate the effect of zinc dialkyl dithio phosphate (ZDDP) films on sticking during hot rolling of a ferritic stainless steel strip. The surface characterization and crack propagation of the oxide scale are very important for understanding the mechanism of the sticking. The high-temperature oxidation of one typical ferritic stainless was conducted at 1373 K (1100 °C) for understanding its microstructure and surface morphology. Hot-rolling tests of a ferritic stainless steel strip show that no obvious cracks among the oxide scale were observed with the application of ZDDP. A finite element method model was …

In this work accumulative roll bonding (ARB) was used to combine AA1050 and AA6061 sheets to produce AA1050/AA1050, AA6061/AA6061 and AA1050/AA6061 laminates with ultrafine grained (UFG) structure. Two sheets of starting materials were roll bonded with 200 °C preheating for 180 s before rolling. The through-thickness residual stress distribution of these laminates processed up to two cycles of ARB was determined by neutron diffraction with spatial resolution of 0.2 mm through 1.5 mm thickness. The measurements also required high accuracy of only few MPa since residual stresses in the laminates peaked at only about 15 MPa. The laminates composed of …

In optically stimulated luminescence (OSL) dating, the single aliquot regenerative-dose (SAR) method has been used extensively for determining equivalent doses (De) in quartz. A variation of the SAR method is the “standardised growth curve” (SGC) method, which has been used as an efficient procedure to save measurement time during dating studies. During the application of the SGC method one establishes the SGC and calculation of the De of an aliquot requires only measurement of the standardised natural dose signal. Recently, a “global standardised growth curve” (gSGC) method was developed as an improved version of the SGC procedure. During the application …

Background: Modern diets, characterised by excess consumption of processed foods, are accompanied by an epidemic of chronic diseases. Cardiovascular disease and depression carry a large burden of disease and often occur together. Poor dietary patterns have been identified as an independent risk factor for depression while healthy diets with minimally processed food are protective. Traditional Mediterranean diets have been shown to reduce risk of cardiovascular disease; however there is a need for clinical trials in people with depression. This paper reports the study protocol of a Mediterranean-style diet intervention conducted in adults with self-reported depression. Methods/design: HELFIMED is a parallel …

Background Prostate-specific antigen (PSA) testing for prostate cancer is controversial. There are unresolved tensions and disagreements amongst experts, and clinical guidelines conflict. This both reflects and generates significant uncertainty about the appropriateness of screening. Little is known about general practitioners' (GPs') perspectives and experiences in relation to PSA testing of asymptomatic men. In this paper we asked the following questions: (1) What are the primary sources of uncertainty as described by GPs in the context of PSA testing? (2) How do GPs experience and respond to different sources of uncertainty? Methods This was a qualitative study that explored general practitioners' …

Background Cervical cancer disproportionately burdens disadvantaged women. Organised cervical screening aims to make cancer prevention available to all women in a population, yet screening uptake and cancer incidence and mortality are strongly correlated with socioeconomic status (SES). Reaching underscreened populations is a stated priority in many screening programs, usually with an emphasis on something like 'equity'. Equity is a poorly defined and understood concept. We aimed to explain experts' perspectives on how cervical screening programs might justifiably respond to 'the underscreened'. Methods This paper reports on a grounded theory study of cervical screening experts involved in program organisation. Participants were …

Confusions And Conundrums During Final Practicum: A Study Of Preservice Teachers' Knowledge Of Challenging Behaviour, Samantha Mcmahon, Valerie Harwood
Confusions And Conundrums During Final Practicum: A Study Of Preservice Teachers' Knowledge Of Challenging Behaviour, Samantha Mcmahon, Valerie Harwood
Faculty of Social Sciences - Papers (Archive)
This chapter describes the psy-knowledges central to preservice teachers' understandings of challenging behaviour. Particularly, it pays attention to the unexpectedly dangerous questions generated when working towards a practical and integrated understanding of how biological, psychological, and ecological factors interact. This chapter deploys Foucauldian discourse analysis to problematize the preservice teachers' shifting and changeable awareness of these causal attributions of behaviour and how this impacts their pedagogy.

Background: A substantial research base documents the benefits of attendance at high-quality early childhood education and care (ECEC) for positive behavioural and learning outcomes. Research has also found that the quality of many young children's experiences and opportunities in ECEC depends on the skills, dispositions and understandings of the early childhood adult educators. Increasingly, research has shown that the quality of children's interactions with educators and their peers, more than any other programme feature, influence what children learn and how they feel about learning. Hence, we sought to investigate the extent to which evidence-based professional development (PD) - focussed on …

Faculty of Social Sciences - Papers (Archive)
This paper presents a study of two international doctoral students' perspectives on preparing to formally present the thesis proposal, which we conceptualise as a threshold in the PhD journey. They participated in a thesis writing group (TWG) that aimed to support international doctoral students to develop aspects of their scholarship in the early stages of their candidature. The case students reported feeling 'stuck' before joining the TWG run by the authors. After the writing group experience, they reported that they had gained confidence and developed the skills and knowledge required to prepare for their proposal presentation. Their perspectives were gathered …

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 …

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 …

A numerical model was established to investigate the micro hydro-mechanical deep drawing process of austenitic stainless steel 304 foil (0.05 mm thickness). Due to the miniaturisation of the specimen size, the effect of grain size, gap distance and radial pressure during drawing process could be prominent. The results indicate that the appropriate radial pressure and gap distance could improve the limit drawing ratio (LDR) of manufactured cylindrical cups by reducing the friction resistance. The maximum LDR obtained in the present work reaches 3.2, which is much higher than that obtained by conventional deep drawing process.
