It utilises two mutually antagonistic neural fields counteracting in patterns similar to that of flexor/extensor muscles controlling the movements in major joints in the human body. Combining local activation and generalised inhibition represented by Amari's neural field equations and extended by the Fitzhugh-Nagumo and Wilson-Cowan activator-inhibitor systems, results in the type of neural attractor dynamics that may lead to spontaneous oscillatory pattern formation. Preliminary simulation data suggest that this approach has utility in enabling a team of autonomous vehicles to navigate in a crowded pedestrian crossing <br/> <br/>Description: Copyright © 2008 Inderscience Enterprises Limited.

Evidence such as this has been used to introduce regulatory policies to reduce the geographical accessibility of EGMs through the reduction of gaming machine numbers in venues. The aim of this paper was to describe the process involved in the 15 per cent reduction in gaming machine numbers in the state of South Australia and the apparent effects on gaming revenue and gambling behaviours. Detailed analysis of objective EGM data as well as survey-based interviews with 400 regular EGM players provided only limited evidence of behavioural changes or significant reductions in gaming revenue. The paper describes the nature of industry responses to circumvent the effects of the reduction in machine numbers and the implications of these findings for future regulatory policies relating to EGM gambling.
