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.

The MOVE study: a study protocol for a randomised controlled trial assessing interventions to maximise attendance at physical activity facilities

BACKGROUND: Physical activity is associated with a host of health benefits, yet many individuals do not perform sufficient physical activity to realise these benefits. One approach to rectifying this situation is through modifying the built environment to make it more conducive to physical activity, such as by building walking tracks or recreational physical activity facilities. Often, however, modifications to the built environment are not connected to efforts aimed at encouraging their use. The purpose of the Monitoring and Observing the Value of Exercise (MOVE) study is to evaluate the effectiveness of two interventions designed to encourage the ongoing use of a new, multi-purpose, community-based physical activity facility. METHODS/DESIGN: A two-year, randomised controlled trial with yearly survey points (baseline, 12 months follow-up, 24 months follow-up) will be conducted among 1,300 physically inactive adult participants aged 18-70 years. Participants will be randomly assigned to one of three groups: control, intervention 1 (attendance incentives), or intervention 2 (attendance incentives and tailored support following a model based on customer relationship management). Primary outcome measures will include facility usage, physical activity participation, mental and physical wellbeing, community connectedness, social capital, friendship, and social support. Secondary outcome measures will include stages of change for facility usage and social cognitive decision-making variables. DISCUSSION: This study will assess whether customer relationship management systems, a tool commonly used in commercial marketing settings, can encourage the ongoing use of a physical activity facility. Findings may also indicate the population segments among which the use of such systems are most effective, as well as their cost-effectiveness.

Night-time continence care in Australian residential aged care facilities: findings from a grounded theory study

BACKGROUND: Continence care commonly disrupts sleep in residential aged care facilities, however, little is known about what staff do when providing continence care, and the factors that inform their practice. AIMS: To describe nurses' and personal careworkers' beliefs and experiences of providing continence care at night in residential aged care facilities. METHODS/DESIGN: Eighteen nurses and personal careworkers were interviewed about continence care, and 24 hours of observations were conducted at night in two facilities. RESULTS/FINDINGS: Most residents were checked overnight. This practice was underpinned by staffs' concern that residents were intractably incontinent and at risk of pressure injuries. Staff believed pads protected and dignified residents. Decisions were also influenced by beliefs about limited staff-to-resident ratios. CONCLUSION: Night-time continence care should be audited to ensure decisions are based on residents' preferences, skin health, sleep/wake status, ability to move in bed, and the frequency, severity and type of residents' actual incontinence.

A randomised controlled trial investigating the effects of Mediterranean diet and aerobic exercise on cognition in cognitively healthy older people living independently within aged care facilities: The Lifestyle Intervention in Independent Living Aged Car

Background: The rapid ageing of the population is becoming an area of great concern, both globally and in Australia. On a societal level, the cost of supporting an ageing demographic, particularly with their associated medical requirements, is becoming an ever increasing burden that is only predicted to rise in the foreseeable future. The progressive decline in individuals' cognitive ability as they age, particularly with respect to the ever increasing incidence of Alzheimer's Disease (AD) and other cognitive complications, is in many respects one of the foundation stones of these concerns. There have been numerous observational studies reporting on the positive effects that aerobic exercise and the Mediterranean diet appear to have on improving cognitive ability. However, the ability of such interventions to improve cognitive ability, or even reduce the rate of cognitive ageing, has not been fully examined by substantial interventional studies within an ageing population. Methods: The LIILAC trial will investigate the potential for cognitive change in a cohort of cognitively healthy individuals, between the ages of 60 and 90 years, living in independent accommodation within Australian aged care facilities. This four-arm trial will investigate the cognitive changes which may occur as a result of the introduction of aerobic exercise and/or Mediterranean diet into individuals' lifestyles, as well as the mechanisms by which these changes may be occurring. Participants will be tested at baseline and 6 months on a battery of computer based cognitive assessments, together with cardiovascular and blood biomarker assessments. The cardiovascular measures will assess changes in arterial stiffness and central pulse pressures, while the blood measures will examine changes in metabolic profiles, including brain derived neurotrophic factor (BDNF), inflammatory factors and insulin sensitivity. Conclusion: It is hypothesised that exercise and Mediterranean diet interventions, both individually and in combination, will result in improvements in cognitive performance compared with controls. Positive findings in this research will have potential implications for the management of aged care, particularly in respect to reducing the rate of cognitive decline and the associated impacts both on the individual and the broader community.

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.

Fear and overprotection in Australian residential aged care facilities: the inadvertent impact of regulation on quality continence care

Aim: Most residents in residential aged care facilities are incontinent. This study explored how continence care was provided in residential aged care facilities, and describes a subset of data about staffs' beliefs and experiences of the quality framework and the funding model on residents' continence care.

Methods: Using grounded theory methodology, 18 residential aged care staff members were interviewed and 88 hours of field observations conducted in two facilities. Data were analysed using a combination of inductive and deductive analytic procedures.

Results: Staffs' beliefs and experiences about the requirements of the quality framework and the funding model fostered a climate of fear and risk adversity that had multiple unintended effects on residents' continence care, incentivising dependence on continence management, and equating effective continence care with effective pad use.

Conclusion: There is a need to rethink the quality of continence care and its measurement in Australian residential aged care facilities.

A privacy-preserving location tracking system for smartphones based on cloud storage

With the widespread use of smartphones, the loss of a device is a critical problem, which results both in disrupting daily communications and losing valuable property. As a result, tracking systems have been developed to track mobile devices. Previous tracking systems focus on recovering the device's locations after it goes missing, with security methods implemented on the clients. However, users' locations are stored in untrusted third-party services, which may be attacked or eavesdropped. In this paper, we propose a system, named Android Cloud Tracker, to provide a privacy-preserving tracking client and safe storing of user's locations. We use cloud storage controlled by users themselves as storage facilities, and they do not need to worry about any untrusted third party. We implement Android Cloud Tracker prototype on Android phones, and the evaluation shows that it is both practical and lightweight: it generates a small amount of data flow and its distributed architecture provides strong guarantees of location privacy while preserving the ability to efficiently track missing devices.

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.

Organizational factors related to the confidence of workers in working with residents with dementia or depression in aged care facilities

OBJECTIVES: There has been limited research examining how organizational factors are associated with the level of confidence of residential aged care staff in managing both residents' depression and the behavioural and psychological symptoms of residents with dementia (BPSD). This study investigated this issue. METHOD: A cross-sectional study design was employed. In total, 255 aged care staff (131 senior staff, 124 junior staff) from 21 residential care facilities participated in the study. All staff completed measures of self-efficacy in managing BPSD as well as confidence in working with older people with depression. They also completed measures of organizational climate (autonomy, cohesion, trust, pressure, support, recognition, fairness and encouragement of innovation) and measures of workplace experience (job role, number of years working in aged care facilities), job stress and satisfaction, and knowledge of depression. RESULTS: The results demonstrated that autonomy, trust, support, and job stress were associated with confidence in managing BPSD, while the factors related to confidence in managing depression were autonomy, support, job stress, job satisfaction, and knowledge of depression. CONCLUSION: These findings highlight that organizational climate factors need to be addressed in order to increase staff confidence in managing BPSD and depression. In particular, the findings demonstrate the importance of fostering organizational environments in which autonomy is promoted and there is support and cooperation among aged care staff. Attention to these factors is likely to increase the confidence of staff as they carry out their carer role.

Cleaning, resistant bacteria, and antibiotic prescribing in residential aged care facilities

Residents of residential aged care facilities (RACFs) are at risk of colonization and infection with multidrug-resistant bacteria, and antibiotic prescribing is often inappropriate and not based on culture-proven infection. We describe low levels of resident colonization and environmental contamination with resistant gram-negative bacteria in RACFs, but high levels of empirical antibiotic use not guided by microbiologic culture. This research highlights the importance of antimicrobial stewardship and environmental cleaning in aged care facilities.

Health services should collect feedback from inpatients at the point of service: opinions from patients and staff in acute and subacute facilities

OBJECTIVE: Point of service feedback (POSF) enables patients to give health services feedback about their experiences during or immediately after care. Despite the increasing use of POSF, little is known regarding patients' and staffs' opinions of this practice and whether they consider it acceptable or useful. The study aimed to determine patient and staff opinions regarding POSF. DESIGN: A cross-sectional survey. SETTING: Acute and subacute healthcare facilities. PARTICIPANTS: Two hundred and forty-seven patients and 221 staff. RESULTS: Participants indicated that patients should be invited to evaluate health services when they are in hospital or subacute care and improving services was the most important reason for doing so. Staff indicated that:• collecting patients' feedback during their stay was an important part of providing care and not an interruption to it (n = 187 of 221, 85%).• collecting patients' feedback was best done with a variety of methods; talking directly with patients during their stay was the preferred option (n = 161 of 219, 74%).More patients preferred to:• give feedback during their stay (51%) than after discharge from care (15%).• give feedback by talking with someone (45%) than completing a questionnaire (31%).Some patients (14%) were concerned about reprisal from staff if they gave negative feedback. CONCLUSIONS: POSF can be acceptable and useful for evaluating health services and should be incorporated into a person-centred approach that allows patients to choose from a variety of feedback options both during and after their stay. To be most useful, feedback should be incorporated into a quality improvement system.

A BDI-based approach for the assessment of driver's decision-making in commuter scenarios

The rapid growth of urban areas has a significant impact on traffic and transportation systems. New management policies and planning strategies are clearly necessary to cope with the more than ever limited capacity of existing road networks. The concept of Intelligent Transportation System (ITS) arises in this scenario; rather than attempting to increase road capacity by means of physical modifications to the infrastructure, the premise of ITS relies on the use of advanced communication and computer technologies to handle today’s traffic and transportation facilities. Influencing users’ behaviour patterns is a challenge that has stimulated much research in the ITS field, where human factors start gaining great importance to modelling, simulating, and assessing such an innovative approach. This work is aimed at using Multi-agent Systems (MAS) to represent the traffic and transportation systems in the light of the new performance measures brought about by ITS technologies. Agent features have good potentialities to represent those components of a system that are geographically and functionally distributed, such as most components in traffic and transportation. A BDI (beliefs, desires, and intentions) architecture is presented as an alternative to traditional models used to represent the driver behaviour within microscopic simulation allowing for an explicit representation of users’ mental states. Basic concepts of ITS and MAS are presented, as well as some application examples related to the subject. This has motivated the extension of an existing microscopic simulation framework to incorporate MAS features to enhance the representation of drivers. This way demand is generated from a population of agents as the result of their decisions on route and departure time, on a daily basis. The extended simulation model that now supports the interaction of BDI driver agents was effectively implemented, and different experiments were performed to test this approach in commuter scenarios. MAS provides a process-driven approach that fosters the easy construction of modular, robust, and scalable models, characteristics that lack in former result-driven approaches. Its abstraction premises allow for a closer association between the model and its practical implementation. Uncertainty and variability are addressed in a straightforward manner, as an easier representation of humanlike behaviours within the driver structure is provided by cognitive architectures, such as the BDI approach used in this work. This way MAS extends microscopic simulation of traffic to better address the complexity inherent in ITS technologies.
