Australia's family law system continues to be plagued by serious delays. This article acknowledges the need for legal interventions in post‐separation parenting disputes in which individuals may be at risk, or in cases of genuine emergency. The article next contrasts cases involving significant risk or urgency with the many ‘ordinary’ (even if sometimes complex) post‐separation disputes over parenting in which these circumstances are not present. I argue that in such cases, legal advice, legally informed dispute processes, and court hearings are remnants from earlier attitudes to separation and divorce. These interventions are expensive, frequently destructive of ongoing parental relationships, and at their heart, inappropriate for considering the needs of children. They also divert time and resources from the critical investigative and legal decision‐making processes needed in urgent or risk‐related cases. I propose that legal narratives in ‘ordinary’ post‐separation parenting disputes be replaced by narratives focused on the main drivers of these disputes, which are invariably expressed in terms of relationship difficulties. Such narratives are amenable to facilitative, therapeutic, and systemic interventions aimed at achieving self‐determined resolutions. They contrast markedly with narratives reflecting common law notion of normative resolutions derived from the application of legal precedent. Key issues in the first section of the article are then teased out via the reflections of an imaginary separated parent in an ‘ordinary,’ albeit difficult and emotionally intense, dispute about how to care for the children. In the final section, I offer brief clinical and systemic reflections on past practice and on future narratives focused on individual self‐determination.  相似文献

This paper addresses the questions of market penetration and locational conflict in a franchise system of distribution. The models developed provide a means to evaluate alternative scenarios and the effects of various franchise policies. It is shown that the market penetration and location goals of the members of a franchise system coincide only under a very limited set of circumstances.  相似文献

In some statistical problems a degree of explicit, prior information is available about the value taken by the parameter of interest, θ say, although the information is much less than would be needed to place a prior density on the parameter's distribution. Often the prior information takes the form of a simple bound, ‘θ > θ1 ’ or ‘θ < θ1 ’, where θ1 is determined by physical considerations or mathematical theory, such as positivity of a variance. A conventional approach to accommodating the requirement that θ > θ1 is to replace an estimator, , of θ by the maximum of and θ1. However, this technique is generally inadequate. For one thing, it does not respect the strictness of the inequality θ > θ1 , which can be critical in interpreting results. For another, it produces an estimator that does not respond in a natural way to perturbations of the data. In this paper we suggest an alternative approach, in which bootstrap aggregation, or bagging, is used to overcome these difficulties. Bagging gives estimators that, when subjected to the constraint θ > θ1 , strictly exceed θ1 except in extreme settings in which the empirical evidence strongly contradicts the constraint. Bagging also reduces estimator variability in the important case for which is close to θ1, and more generally produces estimators that respect the constraint in a smooth, realistic fashion.  相似文献

We present findings from a nonexperimental evaluation of an employment program in which both partners in young, low-income, primarily African-American couples simultaneously participated. Mothers participating in the couples program had larger immediate gains in employment and earnings and decreases in TANF receipt following their exit from the program relative to mothers who received employment assistance as individuals. Fathers showed similar although weaker results. These immediate benefits appeared to be driven by higher rates of program completion among couples’ participants. Couples in which both partners completed the program experienced the largest quarterly earnings gains, and couples with greater earnings’ gains were more likely to still be together one year after the program ended. Mothers’ earnings gains eroded in the two years following program completion and many reported new pregnancies and problems with child care. We suggest directions for future programs and encourage future studies to consider the range of mechanisms associated with a couples focus, including potential motivational benefits and unintended consequences.

Over the past five years the Artificial Intelligence Center at SRI has been developing a new technology to address the problem of automated information management within real- world contexts. The result of this work is a body of techniques for automated reasoning from evidence that we call evidential reasoning. The techniques are based upon the mathematics of belief functions developed by Dempster and Shafer and have been successfully applied to a variety of problems including computer vision, multisensor integration, and intelligence analysis.

We have developed both a formal basis and a framework for implementating automated reasoning systems based upon these techniques. Both the formal and practical approach can be divided into four parts: (1) specifying a set of distinct propositional spaces, (2) specifying the interrelationships among these spaces, (3) representing bodies of evidence as belief distributions, and (4) establishing paths of the bodies for evidence to move through these spaces by means of evidential operations, eventually converging on spaces where the target questions can be answered. These steps specify a means for arguing from multiple bodies of evidence toward a particular (probabilistic) conclusion. Argument construction is the process by which such evidential analyses are constructed and is the analogue of constructing proof trees in a logical context.

This technology features the ability to reason from uncertain, incomplete, and occasionally inaccurate information based upon seven evidential operations: fusion, discounting, translation, projection, summarization, interpretation, and gisting. These operation are theoretically sound but have intuitive appeal as well.

In implementing this formal approach, we have found that evidential arguments can be represented as graphs. To support the construction, modification, and interrogation of evidential arguments, we have developed Gister. Gister provides an interactive, menu-driven, graphical interface that allows these graphical structures to be easily manipulated.

Our goal is to provide effective automated aids to domain experts for argument construction. Gister represents our first attempt at such an aid.  相似文献

The Rural Development Grant operates the Redundant Building Grant which is designed to bring redundant buildings in certain areas into commercial activity. This paper outlines the results of a recent evaluation of the Grant largely based on contacts with more than 400 applicants in nine counties. This survey is used to explore five aspects of rural policy: property development; business performance; job creation; integrated rural development; and aspects of land use planning.  相似文献

Enrollment into unequal schools at the start of formal education is an important mechanism for the reproduction of racial/ethnic educational inequalities. We examine whether there are racial/ethnic differences in school enrollment options at kindergarten, the start of schooling. We use nationally representative data from the Early Childhood Longitudinal Study‐Birth Cohort (ECLS‐B) to model whether parents seek information about their child's school before enrolling, whether parents move to a location so that a child can attend a certain school, or whether parents enroll their child in a school other than the assigned public school. Results indicate that enrollment patterns differ greatly across race/ethnicity. Whereas Black families are the most likely to seek information on a school's performance, White families are the most likely to use the elite option of choosing their residential location to access a particular school. These differences persist when controlling for socioeconomic status and sociogeographic location. Kindergarten enrollment patterns preserve the advantages of White families, perpetuating racial/ethnic disparities through multiple institutions and contributing to intergenerational processes of social stratification. Research should continue to examine specific educational consequences of housing inequities and residential segregation.  相似文献

The most extensively evaluated intervention for auditory hallucinations is Cognitive Behavioural Therapy for Psychosis (CBTp), which is usually delivered in statutory settings by experienced clinicians. In contrast, peer support networks, such as the Hearing Voices Network (HVN), operate informally using peers to normalise and manage voices. This article compares these two approaches to identify points of synergy and difference. Its analysis suggests the two approaches share many features, but also deviate in important ways that could compensate for each other. Instead of competing with each other as might first be thought, they may actually be complementary. Further, HVN may align comfortably with the values and principles of social work. Social workers seeking to engage with voice hearers may be advised to study the underlying principles of each approach to guide the way in which they can capitalise on intervention opportunities to better assist voice hearers.  相似文献
