Modeling and simulation is commonly used to improve vehicle performance, to optimize vehicle system design, and to reduce vehicle development time. Vehicle performances can be affected by environmental conditions and driver behavior factors, which are often uncertain and immeasurable. To incorporate the role of environmental conditions in the modeling and simulation of vehicle systems, both real and artificial data are used. Often, real data are unavailable or inadequate for extensive investigations. Hence, it is important to be able to construct artificial environmental data whose characteristics resemble those of the real data for modeling and simulation purposes. However, to produce credible vehicle simulation results, the simulated environment must be realistic and validated using accepted practices. This paper proposes a stochastic model that is capable of creating artificial environmental factors such as road geometry and wind conditions. In addition, road geometric design principles are employed to modify the created road data, making it consistent with the real-road geometry. Two sets of real-road geometry and wind condition data are employed to propose probability models. To justify the distribution goodness of fit, Pearson's chi-square and correlation statistics have been used. Finally, the stochastic models of road geometry and wind conditions (SMRWs) are developed to produce realistic road and wind data. SMRW can be used to predict vehicle performance, energy management, and control strategies over multiple driving cycles and to assist in developing fuel-efficient vehicles.

For more than forty thousand years Aboriginal people of Australia have been confronted with major climate, ecological and geological changes as well as annual seasonal variations. Many of these changes have been captured in the cultural traditions of Maar (the people) of the south-west Victorian coast and the knowledge has been transferred from generation to generation through Dreaming stories. Many Dreaming stories recount the forming of the coastal landscape and Sea Country. Weather patterns and climate change were gauged by the occurrence of natural events such as the tidal changes, sea level rise, landscape changes, behaviour of animals, and the availability of food sources. Can this ancient knowledge provide answers for adaptation and resilience to a rapid changing climate? Drawing upon recent literature on coastal climate change in the Great Ocean Road Region (GORCC, 2012), literature review of indigenous environmental planning (Kooyang Sea Country Plan, 2004), and investigation of settlement patterns of the Wathaurong and Gadubanud people, this paper reviews the changes in the landscape due to climate change and explores traditional knowledge as input to a potential design based adaptation model for coastal settlements of the Great Ocean Road Region.

Jorge Lorenzo Flores Garza’s On the Road by Jack Kerouac had its Australian premiere in July this year at the Walker Street Gallery in Melbourne. It screened as part of the ‘Outside the Outside’ series curated by Dirk de Bruyn and Glenn D’Cruz, and was introduced by Steven McIntyre.

On the Road by Jack Kerouac is the most recent work by Mexican filmmaker Jorge Lorenzo, whose previous 1/48” (2008) was listed in Cahiers du Cinéma’s top 10 most subversive films of all time. Somewhere between a book on a film, and a film of a book, Lorenzo’s work is an exact re-typing of Jack Kerouac’s On the Road, made by threading a continuous roll of 35mm negative (like Kerouac’s original scroll) through a Olivetti typewriter.

Research on early childhood education emphasises the importance of quality in early childhood intervention. This study examines the quality of Early Childhood Intervention Services based on parents’ experiences raising a child with developmental delay or disability. The study builds on the philosophy of Family-Centred Practice and professionals’ experiences with family-centred interventions. A qualitative case study approach was adopted to gain insight about families who are raising a child with additional needs. Nine in-depth parent-interviews and three focus groups with professionals were conducted in the first two terms of 2010. The case explicates the experiences of parents and professionals who were associated with Specialist Children’s Services in a metropolitan region of Victoria. The research concentrated on the first point of entry to early intervention, the referrals process and the waiting list. It also addressed parents' experiences, priorities and expectations. As a small-scale study, it examined parents’ and children’s needs as well as children’s access to therapy in early intervention. It also investigated community support and parent-professional relationships in the context of early childhood intervention services. The study found that family-centred intervention is beneficial to both parents and children with developmental delay or disability. However, to implement an effective family-centred approach, practitioner support in the form of professional development, supervision and peer mentorship is required to develop professionals’ reflexivity and self-efficacy in family-centred interventions. The study also identified strategies to promote effective practice, gaps in universal and specialised services, and implications for policy.

 This article presents SOR, a vehicular social network to enable social communications and interactions among users on the road during their highway travels. Motivated by the limited connection to Internet contents and services, the essential goal of SOR is to encourage distributed users on the road to spontaneously contribute as the information producer, assembler, and distributer in order to provide timely and localized infotainments to each other through low-cost inter-vehicle communications. To be specific, SOR enables individual users to maintain a personal blog, similar to one on Facebook and Twitter, over which users can create and share personal content information to the public such as travel blogs with pictures and videos. By accessing each other's SOR blogs and commenting on interesting topics, passengers can exchange messages and initiate social interactions. In the specific highway environment, SOR addresses two challenges in the context of vehicular social communications. First, vehicular social communications tend to be frequently interrupted by diverse vehicle mobility and intermittent intervehicle connections, which is annoying to users. To address this issue, SOR adopts a proactive mechanism by estimating the connection time between peer vehicles, and recommending vehicles with relatively long-lasting and stable intervehicle connections for social communications. Second, as users on the road are typically strangers to each other, they are reluctant to disclose personal information to others. This makes it challenging to identify users of shared interests and accordingly restricts the scale of users' social interactions. To remedy that, SOR provides a secured solution to protect sensitive user information during social communications. Lastly, we use simulations to verify the performance of SOR. © 2015 IEEE.

There is a need for psychosocial interventions for men with prostate cancer to promote adaptive coping with the challenges and distress associated with diagnosis, treatment and recovery. In addition, interventions are needed that help to overcome barriers to psychosocial treatment such as limited face-to-face psychosocial support services, a shortage of adequately trained professionals, geographical distance, perceived and personal stigma and a preference for consumer-centric and self-directed learning. My Road Ahead is an online cognitive behaviour therapy (CBT) intervention for prostate cancer. This protocol describes a randomised controlled trial (RCT) that will evaluate the efficacy of this online intervention alone, the intervention in combination with a moderated online forum, and the moderated online forum alone.

Men with prostate cancer are not routinely offered psychosocial support despite strong evidence that being diagnosed with prostate cancer poses significant quality of life concerns and places the patient at elevated risk of developing a range of mental health disorders. The objective of this study was to develop an online psychological intervention for men with prostate cancer and to pilot test the feasibility and acceptability of the intervention. Development of the intervention involved a multidisciplinary collaboration, adapting face-to-face and group intervention strategies for an online format. The full online intervention and moderated forum were pilot tested with 64 participants who were recruited from urology practices in Melbourne, Victoria, Australia. After consenting to participate and creating a personal account in the online programme, participants completed baseline demographic questionnaires. Participants were provided access to the programme for 6-12. weeks. After completing the programme participants completed an online survey to assess intervention and forum utilisation and satisfaction, as well as suggest intervention refinements following their use of the intervention. Patient satisfaction was calculated using mean responses to the satisfaction questionnaire. The intervention was received positively with 47.82% of participants highly satisfied with the programme, and 78.26% said they would recommend it to a friend. Participants' qualitative feedback indicated good acceptability of the online intervention. A number of technical and participant engagement issues were identified and changes recommended as a result of the feasibility testing.
