“Privilege to Kill” phenomenon on developing countries’ roads : a preliminary case study of China

This study aims to examine the severe consequences of traffic crashes related to a special group of drivers in China, which is called the “Second Rich & Powerful Generation” (SRPG). The unique driving behaviors and attitudes of this special group are intertwined with the general cultural and social environment in China. To investigate the difference of traffic crash consequences between drivers who belong to SRPG and general driver population, injuries and fatalities in 2009, 2010, 2011 and 2012 were compared. Results consistently showed that while no significant difference was detected between these two groups in terms of injuries, fatalities per crash caused by SRPG were significantly larger than that caused by general driver population. Findings from our study clearly demonstrate the complexity of road safety issues in developing countries, and can also be used to develop road safety improvement strategies tailored to SRPG.

The feasibility, delivery and cost effectiveness of drink driving interventions : a qualitative analysis of professional stakeholders

Many intervention programs have been designed to decrease the rate of drink driving by altering the behavioural characteristics that may lead a person to drink and drive. However, most programs target high risk and repeat offenders. There is very little research on the feasibility and effectiveness of first offender programs. This project is part of a larger program of research that focuses on first time offenders, in order to reduce the rate of subsequent drink driving which may result in a repeat offence. A number of professional stakeholders were approached and interviewed with a view to capturing and reflecting current drink driving related concerns while developing an intervention in the context of Australian drink driving related legislation. The qualitative interviews involved open ended questioning which led to the themes discussed in the analysis. Included in the interviews were senior representatives from the Magistrates Court, Queensland Transport, Probation & Parole, Queensland Corrective Services, Royal Automobile Club Queensland (RACQ), Intraface Consulting (drug & alcohol EAP), Brisbane Police Prosecution Corps, Queensland Police Service and private practice psychology. Issues such as delivery of interventions, feasibility and cost-effectiveness were discussed, as were potential content and design. It was generally agreed that a tailored online intervention imposed as a sentencing option would be the most effective for first time offenders in terms of cost, ease of delivery and feasibility. The development of an online intervention program for first offenders is widely supported by professional stakeholders.

The antigen 43 structure reveals a molecular velcro-like mechanism of autotransporter-mediated bacterial clumping

Aggregation and biofilm formation are critical mechanisms for bacterial resistance to host immune factors and antibiotics. Autotransporter (AT) proteins, which represent the largest group of outer-membrane and secreted proteins in Gram-negative bacteria, contribute significantly to these phenotypes. Despite their abundance and role in bacterial pathogenesis, most AT proteins have not been structurally characterized, and there is a paucity of detailed information with regard to their mode of action. Here we report the structure–function relationships of Antigen 43 (Ag43a), a prototypic self-associating AT protein from uropathogenic Escherichia coli. The functional domain of Ag43a displays a twisted L-shaped β-helical structure firmly stabilized by a 3D hydrogen-bonded scaffold. Notably, the distinctive Ag43a L shape facilitates self-association and cell aggregation. Combining all our data, we define a molecular “Velcro-like” mechanism of AT-mediated bacterial clumping, which can be tailored to fit different bacterial lifestyles such as the formation of biofilms.

Changes in outdoor workers' sun-related attitudes, beliefs, and behaviors : a pre-post workplace intervention

OBJECTIVE To evaluate changes in outdoor workers' sun-related attitudes, beliefs, and behaviors in response to a health promotion intervention using a participatory action research process. METHODS Fourteen workplaces across four outdoor industry types worked collaboratively with the project team to develop tailored sun protection action plans. Workers were assessed before and after the 18-month intervention. RESULTS Outdoor workers reported increases in workplace support for sun protection (P < 0.01) and personal use of sun protection (P < 0.01). More workers reported seeking natural shade (+20%) and wearing more personal protective equipment, including broad-brimmed hats (+25%), long-sleeved collared shirts (+19%), and long trousers (+16%). The proportion of workers reporting sunburn over the past 12 months was lower at postintervention (-14%) (P = 0.03); however, the intensity of reported sunburn increased. CONCLUSIONS This intervention was successful in increasing workers' sun protective attitudes, beliefs, and behaviors.

Profiling high-range speeding offenders : investigating criminal history, personal characteristics, traffic offences, and crash history

This paper reports profiling information for speeding offenders and is part of a larger project that assessed the deterrent effects of increased speeding penalties in Queensland, Australia, using a total of 84,456 speeding offences. The speeding offenders were classified into three groups based on the extent and severity of an index offence: once-only low-rang offenders; repeat high-range offenders; and other offenders. The three groups were then compared in terms of personal characteristics, traffic offences, crash history and criminal history. Results revealed a number of significant differences between repeat high-range offenders and those in the other two offender groups. Repeat high-range speeding offenders were more likely to be male, younger, hold a provisional and a motorcycle licence, to have committed a range of previous traffic offences, to have a significantly greater likelihood of crash involvement, and to have been involved in multiple-vehicle crashes than drivers in the other two offender types. Additionally, when a subset of offenders’ criminal histories were examined, results revealed that repeat high-range speeding offenders were also more likely to have committed a previous criminal offence compared to once only low-range and other offenders and that 55.2% of the repeat high-range offenders had a criminal history. They were also significantly more likely to have committed drug offences and offences against order than the once only low-range speeding offenders, and significantly more likely to have committed regulation offences than those in the other offenders group. Overall, the results indicate that speeding offenders are not an homogeneous group and that, therefore, more tailored and innovative sanctions should be considered and evaluated for high-range recidivist speeders because they are a high-risk road user group.

Predicting the likelihood of non-healing : a venous leg ulcer risk assessment tool

This project developed, validated and tested reliability of a risk assessment tool to predict the risk of failure to heal of patients with venous leg ulcers within 24 weeks. The risk assessment tool will allow clinicians to be able to determine realistic outcomes for their patients, promote early healing and potentially avoid weeks of inappropriate therapy. The tool will also assist in addressing specific risk factors and guide decisions on early, alternative, tailored interventions.

Australian horror movies and the American market

In Australian cinema since the mid-2000s, horror has become a popular and at times commercially viable genre for low-budget and emerging filmmakers targeting international markets. While the annual horror film output of Australia pales in comparison to that of other Anglophone nations like the United States, Great Britain, and Canada, it has produced several significant titles that have performed moderately well at the international box office, from Wolf Creek (Greg McLean, 2005) to Daybreakers (Michael and Peter Spierig, 2009). Yet as part of a broader tradition of Anglophone horror cinema, many Australian horror movies have been heavily influenced by US and to a lesser extent British horror films. Furthermore, Australian horror film production is largely an internationally-oriented sector that relies on its relationships with overseas distributors and often investors. Consequently, the content and style of Australian horror movies have regularly been tailored for international markets. As a direct consequence some filmmakers have sought to trade on the “Australianness” of their product, others have attempted to pass off their films as faux-American, while others still have attempted to develop placeless films effaced of national reference points. This chapter examines local production as part of a broader tradition of Anglophone horror cinema, the influence of US horror movies, and the limitations of the domestic marketplace. The article concludes with an analysis of how the lure of the US market influences Australian filmmakers’ textual strategies.

Understanding Pathophysiology - ANZ adaptation [1st edition.]

Pathophysiology is a complex, though essential, component of all undergraduate nursing courses and there is an identified need for a text tailored specifically for the Australian and New Zealand student. The entrenched bio-medical terminology can often be difficult to relate to nursing practice. To overcome this, the authors have presented pathophysiology in an accessible manner appropriate to undergraduate students, providing a balance between science, clinical case material and pharmacology. This adaptation prioritises the diseases relevant to nursing students and presents them according to their prevalence and rate of incidence in Australia and New Zealand. This focused approach prepares students for the presentations they will experience in a clinical setting. Each body system is explored first by structure and function, then by alteration.This establishes the physiology prior to addressing the diseases relative to the system and allows the student to analyse and compare the normal versus altered state. A lifespan approach is incorporated in the Alterations chapters, as each chapter addresses childhood diseases through to the aged with respect to each body system. A new section on Contemporary Health Issues examines the effects of an aging population and lifestyle choices on the overall health of our society. These are explored through specific chapters on Stress; Genes and the Environment; Obesity and Diabetes; Cancer; Mental Illness and Indigenous health issues. Concept maps are used to assist students to understand the basic concepts of each chapter and are used as a foundation for more complex discussions. Clinical case studies are also included in each chapter to bring pathophysiology into practice. Each patient case study will highlight relevant symptoms of a given disease within a clinical setting. This is analysed with respect to the relevancy of each given symptom, their respective affect on body systems and the best course of pharmacological treatment. This forthcoming textbook is an adaptation of Understanding Pathophysiology 4e by Huether & McCance. It builds on the strengths of the US edition while tailoring it to the specific needs of Australia and New Zealand undergraduate nursing students. As such it is an invaluable text which will compliment your suite of Elsevier nursing titles.

Queensland's film culture: The challenges of local film distribution and festival exhibition

Organisations at the centre of the state’s industry, such as Screen Queensland, have undergone substantial and ongoing changes in the last five years. Other organisations funded by Screen Queensland, such as QPIX, Queensland’s only film development centre, have recently closed. The Brisbane International Film Festival has been restructured to become the Brisbane Asia Pacific Film Festival as of 2014. In an uncertain industry currently characterised by limited funding and diminishing support structures, local emerging filmmakers require significant initiatives and a sophisticated understanding of how to best utilise fledgling distribution models as part of a tailored strategy for their content. This essay includes interviews with emerging Brisbane filmmakers who have used a combination of traditional and contemporary approaches to exhibition and distribution thus far in their careers. It argues that for these filmmakers, while film festivals do function as crucial platforms for exposure, in the current digital market they cannot be relied upon as the only platform in securing further mainstream or commercial release. They can, however, be incorporated into an alternative distribution model that shows awareness of the contemporary situation in Australia. The research findings are arguably indicative of the challenges faced by filmmakers statewide, and suggest that further support strategies need to be considered to revive Queensland’s film culture and provide immediate support for emerging filmmakers. Queensland’s film sector is currently in the midst of significant change.

Development of an education program to improve care of patients with dementia in an acute care setting

As the population ages, the number of people with dementia in acute care environments is projected to increase rapidly. However, many acute care nurses have undertaken little or no dementia training, potentially leading to reduced quality of care for these patients. This article details the development and delivery of a tailored education program to improve the quality of care of people with dementia in a large, urban hospital in Australia. Designed specifically for the existing context, environment and knowledge levels, the program was developed from multiple inputs, including: expert opinion, literature on workplace and dementia care training, and feedback from participants. The program was delivered to acute care nurses and allied health staff within an outcome based, microteaching model. The broader applicability of the development and delivery techniques used in this program is also discussed.

A communication model and partitioning algorithm for streaming applications for an embedded MPSoC

Energy efficient embedded computing enables new application scenarios in mobile devices like software-defined radio and video processing. The hierarchical multiprocessor considered in this work may contain dozens or hundreds of resource efficient VLIW CPUs. Programming this number of CPU cores is a complex task requiring compiler support. The stream programming paradigm provides beneficial properties that help to support automatic partitioning. This work describes a compiler for streaming applications targeting the self-build hierarchical CoreVA-MPSoC multiprocessor platform. The compiler is supported by a programming model that is tailored to fit the streaming programming paradigm. We present a novel simulated-annealing (SA) based partitioning algorithm, called Smart SA. The overall speedup of Smart SA is 12.84 for an MPSoC with 16 CPU cores compared to a single CPU implementation. Comparison with a state of the art partitioning algorithm shows an average performance improvement of 34.07%.

Binding properties of peptidic affinity ligands for plasmid DNA capture and detection

Peptides constructed from α-helical subunits of the Lac repressor protein (LacI) were designed then tailored to achieve particular binding kinetics and dissociation constants for plasmid DNA purification and detection. Surface plasmon resonance was employed for quantification and characterization of the binding of double stranded Escherichia coli plasmid DNA (pUC19) via the lac operon (lacO) to "biomimics" of the DNA binding domain of LacI. Equilibrium dissociation constants (K D), association (k a), and dissociation rates (k d) for the interaction between a suite of peptide sequences and pUC19 were determined. K D values measured for the binding of pUC19 to the 47mer, 27mer, 16mer, and 14mer peptides were 8.8 ± 1.3 × 10 -10 M, 7.2 ± 0.6 × 10 -10 M, 4.5 ± 0.5 × 10 -8 M, and 6.2 ± 0.9 × 10 -6 M, respectively. These findings show that affinity peptides, composed of subunits from a naturally occurring operon-repressor interaction, can be designed to achieve binding characteristics suitable for affinity chromatography and biosensor devices.

The suitability of DEAE-Cl active groups on customized poly(GMA-co-EDMA) continuous stationary phase for fast enzyme-free isolation of plasmid DNA

The creation of a commercially viable and a large-scale purification process for plasmid DNA (pDNA) production requires a whole-systems continuous or semi-continuous purification strategy employing optimised stationary adsorption phase(s) without the use of expensive and toxic chemicals, avian/bovine-derived enzymes and several built-in unit processes, thus affecting overall plasmid recovery, processing time and economics. Continuous stationary phases are known to offer fast separation due to their large pore diameter making large molecule pDNA easily accessible with limited mass transfer resistance even at high flow rates. A monolithic stationary sorbent was synthesised via free radical liquid porogenic polymerisation of ethylene glycol dimethacrylate (EDMA) and glycidyl methacrylate (GMA) with surface and pore characteristics tailored specifically for plasmid binding, retention and elution. The polymer was functionalised with an amine active group for anion-exchange purification of pDNA from cleared lysate obtained from E. coli DH5α-pUC19 pellets in RNase/protease-free process. Characterization of the resin showed a unique porous material with 70% of the pores sizes above 300 nm. The final product isolated from anion-exchange purification in only 5 min was pure and homogenous supercoiled pDNA with no gDNA, RNA and protein contamination as confirmed with DNA electrophoresis, restriction analysis and SDS page. The resin showed a maximum binding capacity of 15.2 mg/mL and this capacity persisted after several applications of the resin. This technique is cGMP compatible and commercially viable for rapid isolation of pDNA.

Towards the design of a scalable and commercially viable technique for plasmid purification using a methacrylate monolithic stationary phase

A monolithic stationary phase was prepared via free radical co-polymerization of ethylene glycol dimethacrylate (EDMA) and glycidyl methacrylate (GMA) with pore diameter tailored specifically for plasmid binding, retention and elution. The polymer was functionalized. with 2-chloro-N,N-diethylethylamine hydrochloride (DEAE-Cl) for anion-exchange purification of plasmid DNA (pDNA) from clarified lysate obtained from E. coli DH5α-pUC19 culture in a ribonuclease/ protease-free environment. Characterization of the monolithic resin showed a porous material, with 68% of the pores existing in the matrix having diameters above 300 nm. The final product isolated from a single-stage 5 min anion-exchange purification was a pure and homogeneous supercoiled (SC) pDNA with no gDNA, RNA and protein contamination as confirmed by ethidium bromide agarose gel electrophoresis (EtBr-AGE), enzyme restriction analysis and sodium dodecyl sulfate-polyacrylamide gel electrophoresis. This non-toxic technique is cGMP compatible and highly scalable for production of pDNA on a commercial level.

Defence relationship health - deployment impact experience. A prospective study of the impact of deployment on the intimate relationships of Australian Army personnel

A comprehensive literature review has been undertaken exploring the stressors placed on the personal relationships of Australian Army personnel, through service life and also overseas deployments. This work is the first step in a program of research aimed at developing a screening tool, aimed at acting as an early warning system to enable the right assistance to be given to affected personnel at the earliest possible time. It is envisioned that this tool will be utilised by the day-to-day managers of Australian Army personnel, of whom the vast majority are not health practitioners. This review has identified the commonalities of relationships that last through service life and/or deployments, and those that fail. These factors are those which will aid the development of the screening tool, and enable the early identification of Australian Army personnel who are at risk of having their personal relationship break down. Several of the known relationship stressors are relevant to other ‘high intensity’ professions, such as paramedics. Personal experience as an Army Officer has helped to highlight the importance of this research, and the benefits of developing a tool tailored to the unique social microclimate that is the Australian Army are clear. This research is, to the author’s knowledge, unique in the Australian context.
