A sea change on the island continent: frameworks for risk assessment,prevention and intervention in child health in Australia

This article overviews prevention and early intervention approaches focusing specifically on their relevance to the health of children and young people in Australia. Australian public health has a sound track record although concealed within the aggregate profile are a number of sub-populations with poorer health indicators. Recognition of this has increased efforts to improve the health of children and young people especially in exploring the impact of social environments within the communities where children are raised. This paper examines emerging research in this area drawing out key lessons and learning from Australian experience in the field of early intervention and prevention in community settings.     

Behaviour Exchange Systems Training: The ‘BEST’ Approach for Parents Stressed by Adolescent Drug Problems

Parents are challenged in the adolescent years by attempts to increase adolescent responsibility while also managing separation issues. Adolescent drug use can exacerbate parental concerns. Parental fears and anxieties surrounding adolescent drug use can undermine opportunities to respond effectively. This paper describes the theoretical rationale for, and early experience of delivering, a brief intervention program designed to assist parents coping with adolescent drug problems. The program emerges out of a hybrid of systems and behaviour therapy principles and has been designed to address issues associated with parenting characterised by a high level of emotional involvement and/or ineffective parental control. Group work encouraging more adolescent responsibility-taking can assist parents disabled by feelings of guilt and failure. As parents develop emotional independence from adolescent behaviour, an appropriate expectation for adolescent control is established.     

Business games and implementation research

This paper reviews some recent research in OR implementation and suggests that a new approach is required, which will take fuller account of the perceptions of managers concerned with the problem. Research games in business settings seem to offer a means for such approach. Some lessons learned from a business game used in this way are described and their implications for modelbuilders are discussed.     

Longitudinal Prediction of Mid‐Adolescent Psychosocial Outcomes From Early Adolescent Family Help Seeking and Family Support

This study examined whether family help seeking and family support represented the same or distinct constructs and prospective associations between emergent constructs and psychosocial outcomes. Data were from 1,713 school‐based adolescents participating in a randomized controlled trial, in Victoria, Australia. Family help seeking emerged as a single factor, distinct from family support, and was prospectively associated with improved psychosocial outcomes. Father closeness predicted lower depressive symptoms. Family help seeking predicted higher help seeking for peers. Interactions between family help seeking and family support on psychosocial outcomes were not apparent. Findings highlight the importance of examining family help seeking and family support separately in future studies of adolescents' help‐seeking behavior.     

Delinquency,School Context,and Risk Factors in India,Australia, and the United States: Implications for Prevention

There is a dearth of research on delinquency, school context, and risk factors across developed and developing nations. Using representative samples and matched surveys, we examined delinquency among cohorts in Mumbai, India (N = 3,717); Victoria, Australia (N = 1,842); and Washington State (WA), United States (N = 1,828). We used multivariate Poisson hierarchical linear modeling. Risk factor and delinquency levels varied across sites. Delinquency clustered within certain schools, particularly in Mumbai. Community disorganization exhibited an association with delinquency as a school‐level context effect in Mumbai and Victoria. Peer delinquency, sensation seeking, and poor family management exhibited cross‐nationally consistent associations with delinquency. Programs that target schools, the clustering of problem behaviors, and cross‐nationally consistent risk factors should be considered internationally.     

Experience with a multi-year fleet planning model

The fleet planning problem requires determination of the changing airline fleet mix based on existing traffic levels and projected growth, on the existing fleet, various aircraft types available in the future, and other operational and financial considerations. Several applicable mathematical formulations have been reported. One of these has been programmed for the computer and used by the authors for several years. This paper discusses the application of that model to real airline planning situations. Such practical experience has effected changes in the program and the manner it is used in fleet planning studies.     

Does Family Intervention for Adolescent Substance Use Impact Parental Wellbeing? A Longitudinal Evaluation

Adolescent substance abuse is a common problem and family interventions are emerging as a strategy to prevent it and assist family coping. The effectiveness of a prevention‐focussed family intervention was evaluated for its secondary impacts on improving parental mental health and family functioning. Twenty‐four secondary schools in Melbourne Victoria were randomly assigned to either a control condition or an intervention titled Resilient Families. The two intervention levels analysed were: (1) a parenting booklet only and; (2) combining the booklet with face‐to‐face parent education sessions. Parent surveys at baseline were followed up one year and four years later. Repeated‐measures analysis (n = 560) found parents attending parent education demonstrated reductions in mental health symptoms, however this had negative effects on family cohesion and no impact on family conflict. These findings were interpreted in terms of parent education assisting parent mental health by promoting assertive parenting styles that may increase adolescent‐parent tension by encouraging firmer parental boundaries and strategies to reduce adolescent substance use.     

Change for the BEST: Family Changes for Parents Coping with Youth Substance Abuse

This paper reports family changes for participants in a program for parents coping with youth substance abuse. The Behavioural Exchange Systems Training (BEST) program is a professionally‐led, parent training intervention. During 1996 and 1997, six groups of parents participated in the program. High levels of depression were observed at intake, and symptoms demonstrated a stable reduction in association with exposure to the program. Parents tended to achieve success in developing common strategies for assertively managing family problems, though couples from more complex blended families found this more difficult. Adolescent improvements were noted during the weeks observed. A two‐year follow‐up conducted with a subset of families revealed that parents continued to report that the intervention had helped them cope with youth drug abuse.     

Hard and soft constraints in linear programming

The linear programme and its constraints are split into two parts. The first consists of the traditional structure, the second being akin to goal programming. SOFT constraints are weighted relative to each other and then approximately weighted relative to the HARD constraints. The LP is run four times giving different emphasis to the SOFT and HARD constraints. The manager requesting the LP has then to decide which gives the most appropriate solution.
