AbstractDeinstitutionalisation 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. 相似文献

Ancestry and BMI Influences on Facial Soft Tissue Depths for A Cohort of Chinese and Caucasoid Women in Dunedin,New Zealand 下载免费PDF全文

This study measured and assessed facial soft tissue depths (FSTDs) in adult female Chinese and New Zealand (NZ) Europeans (Caucasoids). Ultrasound was used to obtain depths at nine landmarks on 108 healthy subjects (51 Chinese, 57 NZ European), erect positioned, of same age group (18–29 years). Height and weight were also recorded. Statistical analysis focused on comparison of tissue depth between the two ancestry groups and the influence of Body Mass Index (BMI) (kg/m2). Results showed mean depth differences at Supra M2 and Infra M2 landmarks significantly greater for Chinese than Caucasoid women for all three BMI Classes (BMI <20, 20 ≤ BMI < 25, 25 ≤ BMI < 30), even BMI <20. For both groups BMI positively correlated with FSTD values at all landmarks except Labrale superius. This study enabled ancestry and BMI influence on FSTDs to be observed and compared for two distinct groups. Results add to knowledge about facial tissue depth variation. 相似文献

This article examines an underground but emergent neo‐liberal initiative in US cities, historic preservation. A focus on Chicago's programme highlights this as a complex cultural project. The focus is on how narrativists of this programme use imagined mental spaces in discourse to constitute a programme‐ and neo‐liberal‐supporting cultural content for common consumption. The results suggst that this neo‐liberal programme offers elaborate renditions of spatially infused heroes, villains, victims and unmistakable forces that function as cultural frame. This constituting, the study concludes, is crucial to bolstering assertions about the importance of this programme and the need for neo‐liberal restructuring 相似文献
