The Use of 'Shame' with Sexual Offenders

This article explores the use of shaming mechanisms with sexual offenders, particularly those who offend against children. Shaming, a central concept in the broader theory of restorative justice, may be of two varieties. The first, ‘disintegrative shaming’, characterises the traditional retributive framework of justice and is evident in recent state led and popular responses to the risk posed by released sexual offenders. Far from ensuring offender integration, the net result is often labelling, stigmatisation, ostracism and a return to offending behaviour. The second, ‘reintegrative shaming’, affirms the offender’s membership within law abiding society. This has been used in several jurisdictions as the basis of restorative support and treatment networks for sexual offenders where the community works in partnership with state and voluntary agencies. Contrary to arguments put forward by critics of restorative justice, this article argues that such cases may be particularly suitable for a restorative approach.

Exploring the Views of Police Officers on the Use of Video Taped Evidence in Child Abuse Cases in Northern Ireland

This paper sets out to explore the views and attitudes of police officers in the Greater Belfast area, concerning the process and use of video taped interviews with child witnesses, subsequently used as court evidence in child abuse cases. The information was collected by means of a postal questionnaire, completed by police officers who had all experienced joint interviews with social workers of child witnesses. With the increased use of video evidence as an alternative to the distressing experience of a child appearing in court to give evidence, the research findings and conclusions provide clear messages about future developments both nationally and internationally.

The use of morphological characteristics and texture analysis in the identification of tissue composition in prostatic neoplasia

Quantitative examination of prostate histology offers clues in the diagnostic classification of lesions and in the prediction of response to treatment and prognosis. To facilitate the collection of quantitative data, the development of machine vision systems is necessary. This study explored the use of imaging for identifying tissue abnormalities in prostate histology. Medium-power histological scenes were recorded from whole-mount radical prostatectomy sections at × 40 objective magnification and assessed by a pathologist as exhibiting stroma, normal tissue (nonneoplastic epithelial component), or prostatic carcinoma (PCa). A machine vision system was developed that divided the scenes into subregions of 100 × 100 pixels and subjected each to image-processing techniques. Analysis of morphological characteristics allowed the identification of normal tissue. Analysis of image texture demonstrated that Haralick feature 4 was the most suitable for discriminating stroma from PCa. Using these morphological and texture measurements, it was possible to define a classification scheme for each subregion. The machine vision system is designed to integrate these classification rules and generate digital maps of tissue composition from the classification of subregions; 79.3% of subregions were correctly classified. Established classification rates have demonstrated the validity of the methodology on small scenes; a logical extension was to apply the methodology to whole slide images via scanning technology. The machine vision system is capable of classifying these images. The machine vision system developed in this project facilitates the exploration of morphological and texture characteristics in quantifying tissue composition. It also illustrates the potential of quantitative methods to provide highly discriminatory information in the automated identification of prostatic lesions using computer vision.
