In the literature, a need was identified to consider the provision of drinking water to bea ‘high reliability’ societal service. This thesis reports on an investigation into thetechnical and organisational reliability of a defined section in the water utility sectorand a Regional Water...

Explicit approaches to risk analysis within the water utility sector, traditionallyapplied to occupational health and safety and public health protection, are now seeingbroader application in contexts including corporate level decision making, assetmanagement, watershed protection and network...

Few systems operate completely independent of humans. Thus any study of system risk or reliability requires analysis of the potential for failure arising from human activities in operating and managing this. Human reliability analysis (HRA) grew up in the 1960s with the intention of modelling...

We examined the relationship between information processing style and information seeking, and its moderation by anxiety and information utility. Information about Salmonella, a potentially commonplace disease, was presented to 2960 adults. Two types of information processing were examined:...

The paper discusses a new, fully recursive approach to the adaptive modeling, forecasting and seasonal adjustment of nonstationary economic time-series. The procedure is based around a time variable parameter (TVP) version of the well known “component” or “structural” model. It employs a...

Among the alternative Unobserved Components formulations within the stochastic state space setting, the Dynamic Harmonic Regression (DHR) has proved particularly useful for adaptive seasonal adjustment signal extraction, forecasting and back-casting of time series. Here, we show first how to...
