Can we get General Practitioners to Promote Physical Activity? Results of the 10,000 Steps Rockhampton Community-Based Physical Activity Promotion Project

Evidence supporting the efficacy of physical activity promotion in primary care settings has evaluated patient-level changes in physical activity, with little focus on the issue of general practitioner (GP) uptake. The 'GP Strategy' of 10,000 Steps Rockhampton provided an opportunity to explore this issue in the context of a multi-strategy, community-based physical activity intervention project. The 'GP Strategy' was developed in partnership with the Capricornia Division of General Practice. It aimed to: 1) increase GP awareness of the 10,000 Steps project, 2) upskill GPs in brief physical activity counselling techniques, and 3) provide GPs with evidencebased physical activity counselling materials and pedometers. The evaluation, which was guided by the RE-AIM evaluation framework, used a pre-post design, including a GP mailed survey, and collection of process data. Survey response rates were 67% (n=44/66; baseline) and 70% (n=37/53; 14-month follow-up). GP awareness of 10,000 Steps Rockhampton increased from 46% to 97%. 21/23 practices were visited by 10,000 Steps staff and accepted 10,000 Steps posters, brochures, and pedometers. At follow-up, 78% had displayed the poster, 81% were using the brochures, and 70% had loaned pedometers to patients. Despite the very high rate of uptake and use of 10,000 Steps materials, there was no change in the percentage of patients counselled, and relatively few pedometers had been loaned to patients. The results of this trial indicate that it will take more effort to change GP physical activity counselling behaviour, and provide only modest support for use of pedometers in the busy general practice setting.

Feel it and deal with it: mental health practitioners' experiences of exposure to the trauma of survivor clients

Empathic engagement by the trauma therapist with another person's traumatic experiences is believed to create risks for the helping professional. Much attention has been focused upon the mental health professional experiencing symptoms of distress as a result of their exposure to the material of clients who survive traumatic incidents. This thesis contains the findings of a qualitative study that centres on a group of male mental health professionals and their experiences of exposure to the trauma material of survivor clients. The participants of the study practise within an internal Employee Assistance Program that provides, among other duties, a 24 hour, 7 day response to critical incidents to a heavy transport industry. Using semi-structured, in-depth interviews, the effects on the trauma therapists are explored by analysing their reactions to their survivor clients' accounts, the impact of these experiences upon their psychological schema, the organisational culture in which they practise and its influence upon their experiences and the methods participants use to cope with the psychological effects of exposure to trauma material. Participants' experiences are closely examined for critical comparisons with vicarious traumatization. Therapists' responses reveal their continued ability and motivation to empathically engage with the trauma material of survivor clients despite the potential risks.

Air Entrainment Processes in a Full-Scale Rectangular Dropshaft at Large Flows

Rectangular dropshafts, commonly used in sewers and storm water systems, are characterised by significant flow aeration. New detailed air-water flow measurements were conducted in a near-full-scale dropshaft at large discharges. In the shaft pool and outflow channel, the results demonstrated the complexity of different competitive air entrainment mechanisms. Bubble size measurements showed a broad range of entrained bubble sizes. Analysis of streamwise distributions of bubbles suggested further some clustering process in the bubbly flow although, in the outflow channel, bubble chords were in average smaller than in the shaft pool. A robust hydrophone was tested to measure bubble acoustic spectra and to assess its field application potential. The acoustic results characterised accurately the order of magnitude of entrained bubble sizes, but the transformation from acoustic frequencies to bubble radii did not predict correctly the probability distribution functions of bubble sizes.

Free-Surface Aeration and Momentum Exchange at a Bottom Outlet

This study aims to provide some new understanding of the air-water flow properties in high-velocity water jets discharging past an abrupt drop. Such a setup has been little studied to date despite the relevance to bottom outlets. Downstream of the step brink, the free-jet entrains air at both upper and lower air-water interfaces, as well as along the sides. An air-water shear layer develops at the lower nappe interface. At the lower nappe, the velocity redistribution was successfully modelled and the velocity field was found to be similar to that in two-dimensional wake flow. The results highlighted further two distinct flow regions. Close to the brink (Wex < 5000), the flow was dominated by momentum transfer. Further downstream (Wex > 5000), a strong competition between air bubble diffusion and momentum exchanges took place.

Major Issues in Business Process Management: An Expert Perspective

The results presented in this report form a part of a larger global study on the major issues in BPM. Only one part of the larger study is reported here, viz. interviews with BPM experts. Interviews of BPM tool vendors together with focus groups involving user organizations, are continuing in parallel and will set the groundwork for the identification of BPM issues on a global scale via a survey (including a Delphi study). Through this multi-method approach, we identify four distinct sets of outcomes. First, as is the focus of this report, we identify the BPM issues as perceived by BPM experts. Second, the research design allows us to gain insight into the opinions of organisations deploying BPM solutions. Third, an understanding of organizations’ misconceptions of BPM technologies, as confronted by BPM tool vendors is obtained. Last, we seek to gain an understanding of BPM issues on a global scale, together with knowledge of matters of concern. This final outcome is aimed to produce an industry driven research agenda which will inform practitioners and in particular, the research community world-wide on issues and challenges that are prevalent or emerging in BPM and related areas.

Research Quality, Publications and Impact in Hydraulic Engineering into the 21st Century. Publish or Perish, Commercial versus Open Access, Internet versus Libraries

One of the main objectives of the first International Junior Researcher and Engineer Workshop on Hydraulic Structures is to provide an opportunity for young researchers and engineers to present their research. But a research project is only completed when it has been published and shared with the community. Referees and peer experts play an important role to control the research quality. While some new electronic tools provide further means to disseminate some research information, the quality and impact of the works remain linked with some thorough expert-review process and the publications in international scientific journals and books. Importantly unethical publishing standards are not acceptable and cheating is despicable.

Bubbly Flow Structure in Hydraulic Jump

In an open channel, a hydraulic jump is the rapid transition from super- to sub-critical flow associated with strong turbulence and air bubble entrainment in the mixing layer. New experiments were performed at relatively large Reynolds numbers using phase-detection probes. Some new signal analysis provided characteristic air-water time and length scales of the vortical structures advecting the air bubbles in the developing shear flow. An analysis of the longitudinal air-water flow structure suggested little bubble clustering in the mixing layer, although an interparticle arrival time analysis showed some preferential bubble clustering for small bubbles with chord times below 3 ms. Correlation analyses yielded longitudinal air-water time scales Txx*V1/d1 of about 0.8 in average. The transverse integral length scale Z/d1 of the eddies advecting entrained bubbles was typically between 0.25 and 0.4, irrespective of the inflow conditions within the range of the investigations. Overall the findings highlighted the complicated nature of the air-water flow

Prevalence of Parkinson’s disease in metropolitan and rural Queensland: A general practice survey

The prevalence of idiopathic Parkinson’s disease (IPD) in Australia is unclear. We estimated the prevalence of IPD, and other forms of parkinsonism, through the study of typical caseloads in general practice. A random sample of general practitioners (GPs) throughout Queensland (401 responses from 528 validated practice addresses) was asked to estimate the numbers of patients with IPD and parkinsonism seen in the preceding year. The estimated prevalence of diagnosed IPD in Queensland was 146 per 100 000 (95% CI = 136–155). A further 51 per 100 000 in the population were suspected by doctors to have IPD without formal diagnosis, whereas another 51 per 100 000 people may have non-idiopathic parkinsonism. Idiopathic Parkinson’s disease was more common in rural than metropolitan areas. Although most GPs were confident in making diagnoses of IPD, the majority had little or no confidence in their ability to treat the disease, especially in its later stages. Support from neurologists was perceived by GPs to be very good in cities, but poor in remote areas.
