Literacy and numeracy are critical for young people during and after their schooling. The subjects and courses that students undertake during their school years incorporate a range of academic literacy and numeracy practices which students must be able manage if they are to be successful. Pathways beyond schooling also require specific, and changing, understandings of, and proficiencies with, literacy and numeracy as new communication technologies increasingly impact on further study, work, and everyday life. Teaching and learning numeracy is a new emphasis in the SACE and as yet we have little understanding about the ways in which secondary schools handle this area. Students in Years 10 and 11 are at a crucial point in their educational and life pathways as they begin to refine their future aspirations. For those who have difficulty with academic literacies and numeracies – and often a long history of such problems – this period can be fraught unless teachers are able to provide specific support when it is needed, or students are able to access it from care-givers or community members. The School to Work Literacy and Numeracy Project involved teachers from nine schools across the three sectors and university researchers working together to design curriculum interventions for students with a history of low measurable achievement in literacy and/or numeracy. The project started from the premise that working with ‘rich tasks’, an approach to learning and assessment developed in the Productive Pedagogies work undertaken in Queensland (Hayes et al., 2006), would improve students’ motivation, engagement and learning and that this work could best be done by teachers working in school-based, cross-curriculum teams with a school leadership team member and a university researcher as mentor. A key idea in designing rich tasks is that students will have opportunities to demonstrate their learning in assessments which are aligned with the learning expectations (for example a film festival to publicly launch student-produced films, advertising to sell student-made cubby-houses, a household budget based on students’ likely incomes in future work). In other words the assessments should be designed to allow for authentic communication and displays of what the students have learned through serious engagement with the curriculum. The project was conducted from Term 1-4 2009, with follow-up checks with some project teachers in the early weeks of 2010.

Unlicensed driving is a serious problem in many countries, despite ongoing improvements in traffic law enforcement practices and technology. The term ‘unlicensed driver' is generally used to refer to people who operate a motor vehicle or motorcycle without a valid driver's licence, including those who: • have let their licence expire; • have been disqualified or suspended from driving; • hold an inappropriate class of licence for the vehicle they drive; • drive outside the restrictions of a special licence; • don’t currently hold a licence; or • have never held a licence.

Reflective thinking is an important skill in psychology, both as a tool in the therapeutic process and in professional development. The adapted 4Rs Model provides reflective writing structure and highlights the importance of Reporting & Responding, Relating, Reasoning and Reconstructing to students who are new to writing reflections. This chapter presents a case in which the 4Rs model (modified from the 5Rs model in Chap. 2 of this edition) was adopted to support reflective writing skills of undergraduate psychology students in a first year unit and in a final year unit. Although all students reflected on their learning within the units, the support activities leading up to the reflective tasks were adjusted to account for differences in the abilities of the cohorts and the focus of the units. In an evaluation survey, both groups of students endorsed statements about the importance of reflections and the utility of using the model. First year students also reported some difficulties understanding the 4Rs. This chapter will explore how first and final year students can be supported to develop reflection skills through scaffolding and modification of the same approaches and model.

There is debate around the scope of physical assessment skills that should be taught in undergraduate nursing programs. Yet this debate is largely uninformed by evidence on what is learned and practiced by nursing students. This study examined the pattern and correlates of physical assessment skill utilization by 208 graduating nursing students at an Australian university, including measures of knowledge, frequency of use and perceived barriers to physical assessment skills during clinical practice. Of the 126 skills surveyed, on average only five were used every time students practiced. Core skills reflected inspection or general observation of the patient; none involved complex palpation, percussion or auscultation. Skill utilization was also shaped by specialty area. Most skills (70%) were, on average, never performed or learned and students perceived nursing physical assessment was marginalized in both university and workplace contexts. Lack of confidence was thus a significant barrier to use of skills. Based on these findings we argue that the current debate must shift to how we might best support students to integrate comprehensive physical assessment into nursing practice.

Background: Prediction of outcome after stroke is important for triage decisions, prognostic estimates for family and for appropriate resource utilization. Prognostication must be timely and simply applied. Several scales have shown good prognostic value. In Calgary, the Orpington Prognostic Score (OPS) has been used to predict outcome as an aid to rehabilitation triage. However, the OPS has not been assessed at one week for predictive capability. Methods: Among patients admitted to a sub-acute stroke unit, OPS from the first week were examined to determine if any correlation existed between final disposition after rehabilitation and first week score. The predictive validity of the OPS at one week was compared to National Institute of Health Stroke Scale (NIHSS) score at 24 hours using logistic regression and receiver operator characteristics analysis. The primary outcome was final disposition after discharge from the stroke unit if the patient went directly home, or died, or from the inpatient rehabilitation unit. Results: The first week OPS was highly predictive of final disposition. However, no major advantage in using the first week OPS was observed when compared to 24h NIHSS score. Both scales were equally predictive of final disposition of stroke patients, post rehabilitation. Conclusion: The first week OPS can be used to predict final outcome. The NIHSS at 24h provides the same prognostic information.

BACKGROUND The workgroup of Traffic Psychology is concerned with the social, behavioral, and perceptual aspects that are associated with use and non-use of bicycle helmets, in their various forms and under various cycling conditions. OBJECTIVES The objectives of WG2 are to (1) share current knowledge among the people already working in the field, (2) suggest new ideas for research on and evaluation of the design of bicycle helmets, and (3) discuss options for funding of such research within the individual frameworks of the participants. Areas for research include 3.1. The patterns of use of helmets among different users: children, adults, and sports enthusiasts. 3.2. The use of helmets in different environments: rural roads, urban streets, and bike trails. 3.3. Concerns bicyclists have relative to their safety and convenience and the perceived impact of using helmets on comfort and convenience. 3.4. The benefit of helmets for enhancing visibility, and how variations in helmet design and colors affect daytime, nighttime, and dusktime visibility. 3.5. The role of helmets in the acceptance of city-wide pickup-and-drop-off bicycles. 3.6. The impact of helmets on visual search behaviour of bicyclists.

Executive Summary Queensland University of Technology (QUT) was contracted to conduct an evaluation of an integrated chronic disease nurse practitioner service conducted at Meadowbrook Primary Care Practice. This evaluation is a collaborative project with nurse practitioners (NP) from Logan Hospital. The integrated chronic disease nurse practitioner service is an outpatient clinic for patients with two or more chronic diseases, including chronic kidney disease (CKD), heart failure (HF), diabetes (type I or II). This document reports on the first 12 months of the service (4th June, 2014 to 25th May, 2015). During this period: • 55 patients attended the NP clinic with 278 occasions of service provided • Almost all (95.7%) patients attended their scheduled appointments (only 4.3% did not attend an appointment) • Since attending the NP clinic, the majority of patients (77.6%) had no emergency department visits related to their chronic disease; only 3 required hospital admission. • 3 patients under the service were managed with Hospital In the Home which avoided more than 25 hospital bed days • 41 patients consented to join a prospective cohort study of patient-reported outcomes and patient satisfaction • 14 patient interviews and 3 stakeholder focus groups were also conducted to provide feedback on their perceptions of the NP-led service innovation. The report concludes with seven recommendations.

The purpose of this article is to show the applicability and benefits of the techniques of design of experiments as an optimization tool for discrete simulation models. The simulated systems are computational representations of real-life systems; its characteristics include a constant evolution that follows the occurrence of discrete events along the time. In this study, a production system, designed with the business philosophy JIT (Just in Time) is used, which seeks to achieve excellence in organizations through waste reduction in all the operational aspects. The most typical tool of JIT systems is the KANBAN production control that seeks to synchronize demand with flow of materials, minimize work in process, and define production metrics. Using experimental design techniques for stochastic optimization, the impact of the operational factors on the efficiency of the KANBAN / CONWIP simulation model is analyzed. The results show the effectiveness of the integration of experimental design techniques and discrete simulation models in the calculation of the operational parameters. Furthermore, the reliability of the methodologies found was improved with a new statistical consideration.

The development of innovative methods of stock assessment is a priority for State and Commonwealth fisheries agencies. It is driven by the need to facilitate sustainable exploitation of naturally occurring fisheries resources for the current and future economic, social and environmental well being of Australia. This project was initiated in this context and took advantage of considerable recent achievements in genomics that are shaping our comprehension of the DNA of humans and animals. The basic idea behind this project was that genetic estimates of effective population size, which can be made from empirical measurements of genetic drift, were equivalent to estimates of the successful number of spawners that is an important parameter in process of fisheries stock assessment. The broad objectives of this study were to 1. Critically evaluate a variety of mathematical methods of calculating effective spawner numbers (Ne) by a. conducting comprehensive computer simulations, and by b. analysis of empirical data collected from the Moreton Bay population of tiger prawns (P. esculentus). 2. Lay the groundwork for the application of the technology in the northern prawn fishery (NPF). 3. Produce software for the calculation of Ne, and to make it widely available. The project pulled together a range of mathematical models for estimating current effective population size from diverse sources. Some of them had been recently implemented with the latest statistical methods (eg. Bayesian framework Berthier, Beaumont et al. 2002), while others had lower profiles (eg. Pudovkin, Zaykin et al. 1996; Rousset and Raymond 1995). Computer code and later software with a user-friendly interface (NeEstimator) was produced to implement the methods. This was used as a basis for simulation experiments to evaluate the performance of the methods with an individual-based model of a prawn population. Following the guidelines suggested by computer simulations, the tiger prawn population in Moreton Bay (south-east Queensland) was sampled for genetic analysis with eight microsatellite loci in three successive spring spawning seasons in 2001, 2002 and 2003. As predicted by the simulations, the estimates had non-infinite upper confidence limits, which is a major achievement for the application of the method to a naturally-occurring, short generation, highly fecund invertebrate species. The genetic estimate of the number of successful spawners was around 1000 individuals in two consecutive years. This contrasts with about 500,000 prawns participating in spawning. It is not possible to distinguish successful from non-successful spawners so we suggest a high level of protection for the entire spawning population. We interpret the difference in numbers between successful and non-successful spawners as a large variation in the number of offspring per family that survive – a large number of families have no surviving offspring, while a few have a large number. We explored various ways in which Ne can be useful in fisheries management. It can be a surrogate for spawning population size, assuming the ratio between Ne and spawning population size has been previously calculated for that species. Alternatively, it can be a surrogate for recruitment, again assuming that the ratio between Ne and recruitment has been previously determined. The number of species that can be analysed in this way, however, is likely to be small because of species-specific life history requirements that need to be satisfied for accuracy. The most universal approach would be to integrate Ne with spawning stock-recruitment models, so that these models are more accurate when applied to fisheries populations. A pathway to achieve this was established in this project, which we predict will significantly improve fisheries sustainability in the future. Regardless of the success of integrating Ne into spawning stock-recruitment models, Ne could be used as a fisheries monitoring tool. Declines in spawning stock size or increases in natural or harvest mortality would be reflected by a decline in Ne. This would be good for data-poor fisheries and provides fishery independent information, however, we suggest a species-by-species approach. Some species may be too numerous or experiencing too much migration for the method to work. During the project two important theoretical studies of the simultaneous estimation of effective population size and migration were published (Vitalis and Couvet 2001b; Wang and Whitlock 2003). These methods, combined with collection of preliminary genetic data from the tiger prawn population in southern Gulf of Carpentaria population and a computer simulation study that evaluated the effect of differing reproductive strategies on genetic estimates, suggest that this technology could make an important contribution to the stock assessment process in the northern prawn fishery (NPF). Advances in the genomics world are rapid and already a cheaper, more reliable substitute for microsatellite loci in this technology is available. Digital data from single nucleotide polymorphisms (SNPs) are likely to super cede ‘analogue’ microsatellite data, making it cheaper and easier to apply the method to species with large population sizes.

Universities and teacher employment bodies seek new, cost-effective ways for graduating classroom-ready teachers. This study involved 32 final-year preservice teachers in an innovative school-university partnership teacher education program titled, the School-Community Integrated Learning (SCIL) pathway. Data were collected using a five-part Likert scale survey with extended written responses. Survey results showed that preservice teachers involved in the SCIL pathway learnt more about the teaching profession, which extended their usual university coursework. Furthermore, written responses suggested ways for advancing their understandings to ensure preservice teachers receive a quality school experience towards readiness for teaching.
