Distributed improvisation: a systems perspective of improvisation 'epics' by led outdoor activity leaders.

Improvisation represents the spontaneous and real-time conception and execution of a novel response to an unanticipated situation. In order to benefit from the positive safety potential of this phenomenon, it is necessary to understand what influences its appropriateness and effectiveness. This study has applied the system-based methodology Impromaps to analysing accounts of improvisation aimed at mitigating adverse safety outcomes.

Key Factors Influencing Implementation of Falls Prevention Exercise Programs in the Community.

The study aim was to evaluate the implementation of group- and home-based exercise falls prevention programs delivered through community health agencies to community-dwelling older people. Interviews with program staff were guided by the Diffusion of Innovations theory. Highly consistent themes emerged for the two types of programs.

Implementation of evidence-based falls prevention in clinical services for high-risk clients.

Rationale, Aims And Objectives: The extent to which best practice for falls prevention is being routinely delivered by health care providers for community-dwelling older adults is unclear. We investigated falls prevention practice among Hospital Admission Risk Programs (HARP) that provide and coordinate specialized health care for people at high risk of hospitalization.

Method: Cross-sectional survey of all HARP services in Victoria, excluding one paediatric programme (n = 34).

A systems approach to accident causation in mining: an application of the HFACS method.

This project aimed to provide a greater understanding of the systemic factors involved in mining accidents, and to examine those organisational and supervisory failures that are predictive of sub-standard performance at operator level. A sample of 263 significant mining incidents in Australia across 2007-2008 were analysed using the Human Factors Analysis and Classification System (HFACS). Two human factors specialists independently undertook the analysis.

Driver behaviour at rail level crossings: responses to flashing lights, traffic signals and stop signs in simulated rural driving.

Australian road and railway authorities have made a concerted effort to reduce the number of rail level crossings, particularly the higher risk passive crossings that are protected by devices such as 'give way' or 'stop' signs. To improve this situation, passive level crossings are often upgraded with active controls such as flashing red lights. Traffic signals may provide good safety outcomes at level crossings but remain untested.

Effects on driving performance of interacting with an in-vehicle music player: a comparison of three interface layout concepts for information presentation.

Interface design is an important factor in assessing the potential effects on safety of interacting with an in-vehicle information system while driving. In the current study, the layout of information on a visual display was manipulated to explore its effect on driving performance in the context of music selection. The comparative effects of an auditory-verbal (cognitive) task were also explored.
