VOLATILE SUBSTANCES: COORDINATING PETROL-SNIFFING PROGRAMS FOR ABORIGINAL COMMUNITIES IN A FEDERAL SYSTEM

Abstract: This paper considers the problems involved in coordinating policy in a federal system. It examines the programs developed to control petrol-sniffing in South Australian Aboriginal communities and analyses the processes which determined policy outcomes. Both intergovernmental and intragovern-mental factors are identified as contributing to the failure to achieve coordination. The particular characteristics of Aboriginal Affairs as a concurrent constitutional responsibility combined with its position as a client-specific portfolio impede efficiency in matters of funding, definition of administrative jurisdiction and political commitment to cooperative action.     

A Classification Tree Approach to the Development of Actuarial Violence Risk Assessment Tools

Since the 1970s, a wide body of research has suggested that the accuracy of clinical risk assessments of violence might be increased if clinicians used actuarial tools. Despite considerable progress in recent years in the development of such tools for violence risk assessment, they remain primarily research instruments, largely ignored in daily clinical practice. We argue that because most existing actuarial tools are based on a main effects regression approach, they do not adequately reflect the contingent nature of the clinical assessment processes. To enhance the use of actuarial violence risk assessment tools, we propose a classification tree rather than a main effects regression approach. In addition, we suggest that by employing two decision thresholds for identifying high- and low-risk cases--instead of the standard single threshold--the use of actuarial tools to make dichotomous risk classification decisions may be further enhanced. These claims are supported with empirical data from the MacArthur Violence Risk Assessment Study.     

Mental Disorder, Violence, and Gender

Recent studies have reported comparable rates of violence among men and women with mental disorder, raising important issues for clinical risk assessment. This study examines the relationship between gender and violence using data from the MacArthur Violence Risk Assessment Study. Patients in acute psychiatric wards were interviewed 5 times over the year following their discharge to the community. Results showed some differences between men and women in the violence committed immediately following discharge, with rates for men being higher. But the prevalence of violence over the 1 year was similar for female and male discharged patients. However, there were substantial gender differences in the situational context of the violence committed. Men were more likely to have been drinking or using street drugs, and less likely to have been adhering to prescribed psychotropic medication, prior to committing violence. The violence committed by men was more likely to result in serious injury than the violence committed by women, and men were more likely than women to be arrested after committing a violent act. Women were more likely to target family members and to be violent in the home.     

The Benefit Equity Principle and Willingness to Pay for City Services

In 1991 and 1992, the City of Eugene, Oregon engaged in a citizen participation process to determine public support for a variety of spending and budget balancing alternatives. This process, called Eugene Decisions, employed an innovative combination of public forums, budget balancing exercises and representative surveys. Two of the surveys, which included questions about individual service use, are analyzed here in order to test whether the use of city services is related to willingness to pay taxes and fees. The concept of benefit equity is supported if service use is positively associated with willingness to pay.     

Estimating time of death of deer in Missouri; a comparison of three indicators

Estimation of time of death (TOD) of white-tailed deer is important to wildlife law enforcement officers. The purpose of this study was to develop and test a model for estimating TOD of white-tailed deer in Missouri. We compare the utility of carcass temperature, pupil diameter, and rigor mortis as TOD indicators. The effects of body size, ambient temperature, and various carcass handling methods on the estimate were also examined. Data were collected from 1484 deer during the 1995-96 and 1996-97 hunting seasons. Stepwise regression indicated that all three indicators were significant and that body size and ambient temperature could influence the model. Predictive equations were developed for various combinations of the indicators based on practicality and statistical probabilities. TOD was estimated for 28 animals where the exact TOD was known. There was no significant difference between the estimated and known TOD (p = 0.759) and the average of the absolute differences in 1 h and 28 min.     

社会记忆研究:从“集体记忆”到记忆实践的历史社会学

尽管有多个学科和不同背景的学术研究领域做了大量的工作,社会记忆研究仍然是一个缺乏固定范式的、没有中心的、跨学科的事业。要纠正这种相对混乱的局面,我们有必要推进多项工作,将社会记忆视为一个有用的传统和一个可加工的范围,为将来的工作奠定基础。我们需要追溯这项事业的家世,回顾围绕社会记忆之基本定义产生的争论,勾勒出历史的视角,并评价与社会记忆静力学和动力学有关的社会学理论。
