While governments and academic institutions urge researchers to engage with news media, traditional academic values of public disengagement have inhibited many from giving high priority to media activity. In this interview-based study, the authors report on the views about news media engagement and strategies used by 36 peer-voted leading Australian public health researchers in 6 fields. The authors consider their views about the role and importance of media in influencing policy, their reflections on effective or ineffective media communicators, and strategies used by these researchers about how to best retain their credibility and influence while engaging with the news media. …
We All Have A Role In Protecting Children: End The Silence On Abuse, Amy Conley Wright, Lynne M. Keevers

The recent string of major child sexual assault scandals, in Australia and other countries, can create a feeling of disgust and an urge to look away from an ugly reality. Yet we must confront and take collective responsibility for child protection by acknowledging that it happens every day and that we have to talk about it. Societal silence on child sexual abuse protects perpetrators and enables abuse to continue. Child sexual assault is a lot more common than we may think. The Australian Institute of Family Studies reported in 2013 that as many as one in six boys and one …
The Role Of Perceived Speed In Vection: Does Perceived Speed Modulate The Jitter And Oscillation Advantages?, Deborah Apthorp, Stephen Palmisano
The Role Of Perceived Speed In Vection: Does Perceived Speed Modulate The Jitter And Oscillation Advantages?, Deborah Apthorp, Stephen Palmisano

Illusory self-motion ('vection') in depth is strongly enhanced when horizontal/vertical simulated viewpoint oscillation is added to optic flow inducing displays; a similar effect is found for simulated viewpoint jitter. The underlying cause of these oscillation and jitter advantages for vection is still unknown. Here we investigate the possibility that perceived speed of motion in depth (MID) plays a role. First, in a 2AFC procedure, we obtained MID speed PSEs for briefly presented (vertically oscillating and smooth) radial flow displays. Then we examined the strength, duration and onset latency of vection induced by oscillating and smooth radial flow displays matched either …

Late Cortical Plasticity In Motor And Auditory Cortex: Role Of Met-Allele In Bdnf Val66met Polymorphism, James T H Teo, Graham Bentley, Philip Lawrence, Fruzsina Soltesz, Sam Miller, David Wille, Simon Mchugh, Chris Dodds, Bai Lu, Rodney J. Croft, Edward T. Bullmore, Pradeep Nathan

The brain-derived neurotropic factor (BDNF) Val66Met polymorphism has been associated with abnormalities of synaptic plasticity in animal models, and abnormalities in motor cortical plasticity have also been described in humans using transcranial direct current stimulation. No study has yet been done on plasticity in non-motor regions, and the effect of two Met alleles (i.e. 'Met dose') is not well understood. We studied the effect of the BDNF Val66Met polymorphism on the after-effects of transcranial direct current stimulation and tetanic auditory stimulation in 65 subjects (23; Val66Val, 22; Val66Met and 20; Met66Met genotypes). In the first session, motor evoked potentials (MEP) …
Removal Of Pharmaceuticals, Steroid Hormones, Phytoestrogens, Uv-Filters, Industrial Chemicals And Pesticides By Trametes Versicolor: Role Of Biosorption And Biodegradation, Luong Nguyen, Faisal Ibney Hai, Shufan Yang, Jinguo Kang, Frederic Leusch, Felicity Roddick, William E. Price, Long D. Nghiem

This study reports the removal of 30 diverse trace organic contaminants (TrOC) by live (biosorption þ biodegradation), intracellular enzyme-inhibited and chemically inactivated (biosorption only) whole-cell preparations and the fungal extracellular enzyme extract (predominantly laccase) from Trametes versicolor (ATCC 7731). Because phenolic substrates are amenable to degradation by laccase, all 14 phenolic TrOC were readily biodegraded. On the other hand, only eight of the 16 non-phenolic TrOC were readily biodegraded while the removal of hydrophilic TrOC (log D < 3) was negligible. With the exception of diclofenac, no non-phenolic TrOC were degraded by the extracellular enzyme extract. The whole-cell culture showed considerably higher degradation of at least seven compounds, indicating the importance of biosorption and subsequent degradation by intracellular and/or mycelium associated enzymes. Improvement (20e90%) of enzymatic degradation of four phenolic and seven non-phenolic TrOC was achieved in the presence of a redox mediator. Compared with the whole-cell culture, mediator-amended extracellular extract achieved better removal of six TrOC, but lower removal of six others. A particular concern was the increased toxicity of the treated media when the redox-mediator was used. In addition to reporting the white-rot fungal removal of two UV filters, three phytoestrogens and a few other pharmaceutically active TrOC for the first time, this study provides unique insights into their removal mechanisms.

The modelling of complex workflows is an important problem-solving technique within healthcare settings. However, currently most of the workflow models use a simplified flow chart of patient flow obtained using on-site observations, groupbased debates and brainstorming sessions, together with historic patient data. This paper presents a systematic and semi-automatic methodology for knowledge acquisition with detailed process representation using sequential interviews of people in the key roles involved in the service delivery process. The proposed methodology allows the modelling of roles, interactions, actions, and decisions involved in the service delivery process. This approach is based on protocol generation and analysis techniques …

The dynamic properties of a soil are routinely quantified to describe its engineering behaviour under repeated loading. While the results of previous research studies indicate that the effect of changes in suction on the dynamic response is significant, only limited research has been engaged in the assessment of post-compacted changes in suction induced by cycles of wetting and drying. In this paper, aspects related to the dynamic properties with special reference to small strain shear modulus behaviour at different compaction energy levels are described and outlined. Particular emphasis is placed on the hysteric behaviour observed (i.e. amplitude of the hysteresis …

Fouling behaviour and its impact on the rejection of trace organic contaminants (TrOCs) by forward osmosis (FO) were investigated.Membrane fouling was simulated using humic acid and colloidal particles asmodel foulants at different initial permeatewater fluxes.Water flux declinewas insignificant at an initial permeate flux of 9 L/m2h and the fouling layerwas loose and fluid-like. By contrast, thewater flux declinewas substantial at an initial permeate flux of 20 L/m2h, resulting in the formation of a compact fouling layer. Water flux recovery after physical cleaning for both humic acid and colloidal particle fouledmembraneswas consistently higher at an initial permeate flux of 9 L/m2h …

The commissioning of treatment planning systems and beam modeling requires measured input parameters. The measurement of relative output in-air, Sc is particularly difficult for small fields. The purpose of this study was to investigate the influence of miniphantom design and detector selection on measured Sc values for small fields and to validate the measurements against Monte Carlo simulations. Measurements were performed using brass caps (with sidewalls) or tops (no sidewalls) of varying heights and widths. The performance of two unshielded diodes (60012 and SFD), EBT2 radiochromic film, and a fiber optic dosimeter (FOD) were compared for fields defined by MLCs …

The effect of phases and steel processing on hydrogen uptake (diffusible and residual), surface and internal damage were evaluated using optical and scanning electron microscopy. The results have shown the fastest formation of blisters in ferrite-pearlite microstructure of strip, followed by equaixed ferrite-pearlite microstructure in normalised condition, then by ferrite-bainite microstructure. No blistering was observed in heat affected zone samples for up to 24 hrs charging. Analysis of hydrogen-induced cracking using electron back scattering diffraction has revealed that crack propagation has predominantly intragranular character without a clear preference on {001}, {110}, {112} and {123} planes and is independent of the …
