The aim was to explore the utility of Keyes' concept of mental health in a substance addiction context. Mental health is considered the presence of emotional wellbeing in conjunction with high levels of social and psychological functioning. Using Keyes' measure, the frequency of languishing and flourishing is compared between clients who became abstinent and those continuing to use substances following treatment. It was hypothesised that there would be a significant interaction between substance use and levels of mental health over time. Participants were 794 individuals (79.5% male) attending residential substance abuse treatment provided by The Australian Salvation Army. The current …

This paper shares findings from part of a larger project exploring students' interpretations of children's literature during independent reading time. Examined in this paper are interpretations by students in Grade 4 (aged 9-10 years) about the messages conveyed in the almost wordless picture book 'Mirror' by author and artist Jeannie Baker. 'Mirror' shares a multicultural perspective on life through its portrayal through collage of the lives of two families living in different countries. Data were collected as semi-structured interviews and observations recorded as field notes. Chambers' (1994) 'Tell Me' framework informed the question schedule of the semi-structured interviews, which were …
If A Safety Aid Is Present, There Must Be Danger: The Paradoxical Effects Of Hand Sanitizer During A Contamination Exposure Task, Shannon M. Blakey, Brett J. Deacon

Perceptions of danger often arise in the context of feared threat cues, but individuals also rely on other heuristics that lead them to infer danger in ambiguous situations. For example, individuals may interpret their own anxiety or safety-seeking behaviors as indicators of threat. Another potential source of danger information is the mere availability of safety aids in the environment. Although assumed to be helpful, safety aids might paradoxically elicit, rather than alleviate, anxiety. The present study was designed to assess the degree to which concern-relevant safety aids exacerbate distress. Participants (N = 71) completed several self-report measures and engaged in …

Professional experience has been described as a cornerstone of teacher preparation that has a "profound impact on student teachers" (Hammerness, Darling-Hammond, & Shulman, 2002, p. 409). There is a wide variation of teacher education programs across the world however, in most countries teacher preparation programs consists of initial university-based course work followed by school-based student teaching practice. Clearly, this program structure has implications for the role of professional experience in creating genuine opportunities for pre-service teachers to develop teaching practice and knowledge about the profession. During the professional experience, mentoring pre-service teachers has been considered critical in ensuring a quality …

An In-Situ Neutron Diffraction Study Of A Multi-Phase Transformation And Twinning-Induced Plasticity Steel During Cyclic Loading, Ahmed A. Saleh, Donald W. Brown, Elena V. Pereloma, Bjorn Clausen, Christopher H. J Davies, Carlos N. Tome, Azdiar A. Gazder

In-situ neutron diffraction during cyclic tension-compression loading (þ3.5% to 2.8%) of a 17Mn-3Al-2Si-1Ni-0.06C steel that exhibits concurrent transformation and twinning -induced plasticity effects indicated a significant contribution of intragranular back stresses to the observed Bauschinger effect. Rietveld analysis revealed a higher rate of martensitic transformation during tension compared to compression. Throughout cycling, a0-martensite exhibited the highest phase strains such that it bears an increasing portion of the macroscopic load as its weight fraction evolves. On the other hand, the e-martensite strain remained compressive as it accommodated most of the internal strains caused by the shape misfit associated with the c!e …

The Acoustic Emission (AE) monitoring technique is widely used in mechanical and material research for detection of plastic deformation, fracture initiation and crack growth. However, the influence of AE features (such as signal amplitude, frequency, rise time and duration) on the fracture parameters (such as brittle or ductile mode of propagation and fracture propagation speed) is not completely understood. In this paper, the effect of loading conditions on fracture behavior was studied using AE monitoring during tensile testing of an aluminum alloy specimen. The fracture development was observed using a high speed video camera and was analyzed using the finite …

High-speed steel (HSS) materials are universally used as work rolls for the hot rolling of stainless steels. Their use has increased the output of the rolling mill and decreased roll material consumption and grinding. Sticking defects often occur, however, during the hot rolling process. In this article, extreme pressure (EP) additives were dropped on the HSS samples at high temperature. Zinc dialkyl dithiophosphate (ZDDP) was chosen as the most effective EP additive by scratch tests on the HSS samples. In order to determine the optimum proportion of ZDDP in the lubricant, two reduction rates were tested on a Hille 100 …

This paper presents an investigation of the fracture behavior of X70 pipeline steel using the acoustic emission (AE) monitoring technique. The AE monitoring technique is widely used in mechanical and materials research for detection of plastic deformation, fracture initiation and crack growth. However, quantitative dependences of the AE parameters (such as signal amplitude and frequency) on the fracture parameters of X70 pipeline steel (such as ductile and brittle fracture initiation and propagation) have not been studied in depth and are therefore not completely understood. In this paper, we report an investigation of the effect of loading conditions on the fracture …

A high manganese TRIP-TWIP steel was cold rolled to 42% thickness reduction and isochronally annealed between 600 to 900 °C for 300 s. The microstructural evolution during annealing was studied by high resolution electron back-scattering diffraction. After cold rolling, the steel comprised predominant fraction of α′-martensite, a small fraction of blocky ε-martensite and a trace fraction of retained austenite (γ). During annealing, the reversion of ε and α′ martensite to γ was followed by the recrystallisation of γ. While the processes of reversion to and recrystallisation of γ were completed by 700 °C, further annealing between 750 to 900 °C …

Objective: This study examines the associations of childhood attention-deficit/hyperactivity disorder (ADHD) risk status with subsequent parental social network characteristics and caregiver strain in adolescence; and examines predictors of adolescent mental health service use. Methods: Baseline ADHD screening identified children at high risk (n = 207) and low risk (n = 167) for ADHD. At eight-year follow-up, parents reported their social network characteristics, caregiver strain, adolescents' psychopathology and mental health service utilization, whereas adolescents self-reported their emotional status and ADHD stigma perceptions. Analyses were conducted using ANOVAs and nested logistic regression modeling. Results: Parents of youth with childhood ADHD reported support …

The majority of distributed generation (DG) units utilize three phase voltage source inverter (VSI) to exchange electric power with the utility grid. The VSI employs semiconductor devices (SDs) with limited current withstand capabilities which are very vulnerable during grid faults. However, to ensure a secure and reliable operation of power systems at high penetration level of the DGs, most of the new grid codes worldwide require that the VSIs must have fault ride-Through (FRT) capability. This paper presents a DC link fault current limiter (DLFCL) based VSI FRT scheme to improve its FRT capability. In the proposed scheme, the DLFCL …
