Achieving Improved Health Outcomes for Urban Aboriginal People: Biomedical and Ethnomedical Models of Health

Urban Aboriginal people could be expected to achieve positive health outcomes owing to their close proximity to mainstream health care services. The available data indicate that this is not the case, although people generally self-report as being in 'good to excellent' health. Research indicates that Aboriginal people may not be benefiting from mainstream services owing to the emphasis placed on biomedical models of health that conflict with more culturally-based, ethnomedical models. This paper looks at achieving an interface between the two models as a means of pursuing more positive health outcomes in urban settings.     

AN EVALUATION OF SUPERVISED ACCESS III

Although supervised access has become a more frequently used option within the custody and access domain over the last 10 years, no empirical literature has examined supervised access from the standpoint of its effect on the legal system. As part of a large-scale evaluation of Ontorio's Supervised Access Pilot Project, the present study sought the perceptions of the legal community and the courts regarding supervised access centers. A total of 14 lawyers and 13 judges participated in semistructured telephone interviews concerning supervised access cases in general, the function and impact of the supervised access program in their community, and their satisfaction with and recommendations regarding the center. Both lawyers and judges expressed high levels of satisfaction with the centers and believed that their availability resulted in savings to the legal system and reductions in hostility and conflict between parents. Implications and limitations of the study are discussed.     

Searchable talk: the linguistic functions of hashtags

An important dimension of social media discourse is its searchability. A key semiotic resource supporting this function is the hashtag, a form of social tagging that allows microbloggers to embed metadata in social media posts. While popularly thought of as topic-markers, hashtags are able to construe a range of complex meanings in social media texts. This paper uses the concept of linguistic metafunctions, to explore how hashtags enact three simultaneous communicative functions: marking experiential topics, enacting interpersonal relationships, and organizing text. Corpus-based discourse analysis of linguistic patterns in a 100 million word Twitter corpus is used to investigate these functions and how they relate to the notion of social search.     

People with special needs and sexual behaviour problems: balancing community and client interests while ensuring effective risk management

Abstract

Deinstitutionalisation movements of the mid-1900s led to changes in policy and practice in the management of people with special needs (defined for this article as people with severe and persistent mental illness, intellectual disabilities and high levels of personality factors that interfere with treatment participation). Although the majority of clients with special needs receive care in community settings and interact more with family, friends and others in the community, some such clients require more rigorous case management. For clients who have offended, especially sexually, community-based services are scarce, and concerns regarding reoffence potential often supersede traditional understandings of diminished capacity. Recent reports suggest that jails and prisons have replaced hospitals as the institutions-of-choice for clients with special needs who engage in inappropriate conduct. This paper examines policies and practices regarding community risk management of people with special needs who have sexually offended. Vignettes are provided to illustrate how some clients and agencies have been affected, and suggestions are made to ensure best practices in risk management and public safety.     

Three-dimensional surface topography acquisition and analysis for firearm identification

In the last decade, computer-based systems for the comparison of microscopic firearms evidence have been the subject of considerable research work because of their expected capability of supporting the firearms examiner through the automated analysis of large amounts of evidence. The Integrated Ballistics Identification System, which is based on a two-dimensional representation of the specimen surface, has been widely adopted in forensic laboratories worldwide. More recently, some attempts to develop systems based on three-dimensional (3D) representations of the specimen surface have been made, both in the literature and as industrial products, such as BulletTRAX-3D, but fundamental limitations in achieving fully automated identification remain. This work analyzes the advantages and disadvantages of a 3D-based approach by proposing an approach and a prototype system for firearms evidence comparison that is based on the acquisition and analysis of the 3D surface topography of specimens, with particular reference to cartridge cases. The concept of 3D virtual comparison microscope is introduced, whose purpose is not to provide fully automated identification, but to show how the availability of 3D shape information can provide a whole new set of verification means, some of them being described and discussed in this work, specifically, visual enhancement tools and quantitative measurement of shape properties, for supporting, not replacing, the firearm examiner in reaching the final decision.     

Intellectual disability and mental illness in the NSW criminal justice system

There has been increasing international, national and local recognition of the need for more appropriate responses and services for individuals who come in contact with the criminal justice system and who have an intellectual disability and mental health issues. This article provides an overview of prevalence data that indicates a significant over representation of people with intellectual disabilities in correctional facilities and reviews the problems facing this population. Findings from two specific evaluation studies undertaken by the Centre for Developmental Disability Studies are presented, along with recommendations for future provision based on these results. One of these projects trialled a case management approach to supporting offenders with an intellectual disability upon their release from prison. The 20-month follow-up found that a number of serious barriers were encountered within the overall system of provision for this population; the most serious of which related to lack of adequate accommodation upon release. The second project involved a two-stage evaluation of one model of provision for individuals with intellectual disabilities who are sex offenders, only some of whom were on parole. This service provided both residential and therapy services in a small group home located in the community. Residents were found to have high levels of emotional and behavioural difficulties, in addition to offending behaviour, that continue to require support and supervision. Critical issues, including guardianship involvement, restrictive practices and retrieval, therapy provision, and risk management issues are discussed in relation to overall clinical and lifestyle outcomes.     

Max Frei theory revisitation: does really strokes depth change along time?

A serious problem in questioned document examination is to establish the age of written lines. With respect to paper dating, in the past, Max Frei theory (based only on microscope analysis) claimed that strokes are time-dependent. Therefore, according to this theory, it has been asserted that from the analysis of the strokes depth changes it is possible to try to date the handwritten document (to find out that the document is older than ...). In the present work, we investigate the strokes depth change by a laser profilometer considering not only the time but also microclimatic variations. First, we analyze the stability of stroke characteristics along the time. In particular, we demonstrate that if the document is preserved without change of temperature and humidity, the depth of the strokes has not appreciable changes. In this way, we have the purpose to verify the real possibility of documents dating by means of Max Frei theory. Subsequently, we test how the 3D profile of strokes changes in connection with the microclimatic variations. In particular, we test humidity variations. With this experiment, we show that humidity variations reduce the strokes depth. Moreover, this effect shows a non-linear trend, leaving a hysteresis on the depth. Finally, we show that the analysis of 3D stroke profile is unable to determine the age of documents.
