Estimating fatality rates in occupational light vehicle users using vehicle registration and crash data

Objective: To estimate occupational light vehicle (OLV) fatality numbers using vehicle registration and crash data and compare these with previous estimates based on workers' compensation data. Method: New South Wales (NSW) Roads and Traffic Authority (RTA) vehicle registration and crash data were obtained for 2004. NSW is the only Australian jurisdiction with mandatory work-use registration, which was used as a proxy for work-relatedness. OLV fatality rates based on registration data as the denominator were calculated and comparisons made with published 2003/04 fatalities based on workers' compensation data. Results: Thirty-four NSW RTA OLV-user fatalities were identified, a rate of 4.5 deaths per 100,000 organisationally registered OLV, whereas the Australian Safety and Compensation Council (ASCC), reported 28 OLV deaths Australia-wide. Conclusions: More OLV user fatalities were identified from vehicle registration-based data than those based on workers' compensation estimates and the data are likely to provide an improved estimate of fatalities specific to OLV use. Implications: OLV-use is an important cause of traumatic fatalities that would be better identified through the use of vehicle-registration data, which provides a stronger evidence base from which to develop policy responses.

Can smartphone users turn off tracking service settings?

Tracking services play a fundamental role in the smartphone ecosystem. While their primary purpose is to provide a smartphone user with the ability to regulate the extent of sharing private information with external parties, these services can also be misused by advertisers in order to boost revenues. In this paper, we investigate tracking services on the Android and iOS smartphone platforms. We present a simple and effective way to monitor traffic generated by tracking services to and from the smartphone and external servers. To evaluate our work, we dynamically execute a set of Android and iOS applications, collected from their respective official markets. Our empirical results indicate that even if the user disables or limits tracking services on the smartphone, applications can by-pass those settings and, consequently, leak private information to external parties. On the other hand, when testing the location 'on' setting, we notice that generally location is not tracked.

Training AAC users in user-centred design

User-centred design (UCD) with a focus on usability provides product developers with a design approach in which users are involved in every stage of the process: when gathering requirements; when evaluating alternative designs; and when evaluating interactive prototypes.The characteristics of people who use augmentative and alternative communication (AAC) make it difficult to follow a truly UCD approach, which in part may contribute to the high rejection of AAC devices. Training workshops have been delivered to introduce users and AAC professionals to the UCD process.Initial feedback indicates that they feel more empowered to evaluate systems and to engage in the design of new systems after attending the workshop.

Comparing subjective well-being and health-related quality of life of Australian drug users in treatment in regional and rural Victoria

The aim of this study is to examine the self-reported subjective well-being and health-related quality of life (HRQOL) of alcohol and other drug users and to examine whether subjective well-being in this sample would be predicted by either HRQOL and/or severity of dependence.

Are the popular users always important for information dissemination in online social networks?

This article verifies the importance of popular users in OSNs. The results are counter-intuitive. First, for dissemination speed, a large amount of users can swiftly distribute information to the masses, but they are not highly-connected users. Second, for dissemination scale, many powerful forwarders in OSNs cannot be identified by the degree measure. Furthermore, to control dissemination, popular users cannot capture most bridges of social communities.

Security and privacy of users' personal Information on smartphones

 This research investigated the proliferation of malicious applications on smartphones and a framework that can efficiently detect and classify such applications based on behavioural patterns was proposed. Additionally the causes and impact of unauthorised disclosure of personal information by clean applications were examined and countermeasures to protect smartphone users’ privacy were proposed.

Taking the good life to the institution: forensic service users' perceptions of the good lives model

Previous literature has highlighted a number of concerns about forensic care and rehabilitation by those who use the services. The Good Lives Model (GLM) is a strength-based, humanistic approach to offender rehabilitation that has been largely overlooked by forensic mental health practitioners. This study explored the impact of a brief GLM program on forensic service users' perceptions of rehabilitation, both within and beyond therapeutic programs, using a thematically linked, multiple-case study research design. Pre-post comparisons of participants' perceptions of rehabilitation suggested three different outcomes: definite change, subtle change, and no change. Possible factors associated with participants' divergent experiences included level of exposure to the GLM, readiness to change, and practitioners' adherence to the GLM and experience with the model. The importance of attending to the wider system for successful implementation of this innovative approach is highlighted.

Do performance and image enhancing drug users in regional Queensland experience difficulty accessing health services?

INTRODUCTION AND AIM: To understand health service access and needs of people who use performance and image enhancing drugs (PIED) in regional Queensland. DESIGN AND METHODS: Semi-structured interviews were conducted with 21 people (n = 19 men) who reported the use of a range of PIEDs, including anabolic-androgenic steroids, human chorionic gonadotropin, growth hormone, clenbuterol, tamoxifen, insulin and peptides. RESULTS: Participants reported accessing a range of services, including needle and syringe programs and pharmacies, for sterile injecting equipment. While PIEDs users attributed some stigma to needle and syringe programs, they were seen as an important service for injecting equipment. Participants reported receiving either positive care from health-care providers, such as general practitioners (GP), or having negative experiences due to the stigma attached with PIED use. Few participants reported disclosing their PIED use to their GP not only because of the concerns that their GP would no longer see them but also because they felt their GP was not knowledgeable about these substances. DISCUSSION AND CONCLUSION: Participants in the study reported no difficulty in accessing health services based on living in a regional area, with their concern focused more upon how they were viewed and treated by service staff.
