Modelling of fibre-diameter-dependent light scattering to determine diameter corrections for colour measurement of wool

In this paper, fibre-diameter-dependent light scattering during measurement of wool colour was quantified using the extended multiplicative signal correction technique. Furthermore, a simple-to-apply model has been developed to correct each of the CIE (International Commission on Illumination) X, Y and Z values obtained from colour measurement of fibrous masses. The model was successfully applied to both polypropylene (PP) and wool fibres, though different parameter values were used in each case, indicating different patterns of internal light scattering between PP and wool fibres. After the model corrections, the diameter dependence of measured wool yellowness (Y - Z) was either eliminated or significantly reduced for each of seven sheep flocks distributed widely over the wool-growing regions of Australia.

Case management in community corrections : current status and future directions

Case management is commonly regarded as the foundation of effective service provision across a wide range of human service settings. This article considers the case management that is offered to clients of community corrections, identifying the distinctive features of case management in this particular setting, and reviewing the empirical evidence relating to the effectiveness of different approaches. It is concluded that models of correctional case management that are clearly informed by the principles of risk, need, and responsivity, and which encourage case managers to form strong and meaningful relationships with their clients, are likely to be the most effective.

The corrections Victoria program change manual

This manual has been written to guide the assessment of change in each of the programs currently offered by the Offending Behaviour Programs Branch, Corrections Victoria. The aim is to identify a set of outcome measures that can be used to both evaluate the overall effectiveness of a program as well as inform judgements about the changes that individual offenders have made over the course of their program participation. Accordingly, the focus is on the assessment of short-term change and not on other areas of assessment, such as assessing changes in risk of reoffending, identifying intervention needs, or establishing an offender’s suitability or eligibility to take part in a program.
