Setting Priorities in the National Campaign Against Drug Abuse

In its ‘National Campaign Against Drug Abuse’, the Federal Government has decided to give top priority in the 1987 financial year to preventing the use of heroin and cocaine, particularly among the young. After reviewing the drug consumption habits of North Queenslanders, we conclude that this decision does not address the most immediate drug-related health problems of the region. Our data suggest not only that legal drugs pose a far greater threat to the health and welfare of Australian society but also that drug abuse is primarily concentrated within the adult population.     

Predictors of Adolescent Adjustment: Parent-Peer Relationships and Parent-Child Conflict

A telephone survey of 114 mothers and their sons, 132 mothers and their daughters, 64 fathers and their sons, and 64 fathers and their daughters investigated the predictors of adolescent adjustment, as separately estimated by parents and their children. Results revealed that the best predictors of adolescent adjustment were the level of conflict within the household over mundane domestic matters and the parent's general disposition towards the child's friends. When results were broken into parent-child gender dyads (mother-son, mother-daughter, father-son, father-daughter), it emerged that the father's perceptions tended to be the dominant predictor of adolescent male adjustment.     

Free triples,large indifference classes and the majority rule

We study classes of voting situations where agents may exhibit a systematic inability to distinguish between the elements of certain sets of alternatives. These sets of alternatives may differ from voter to voter, thus resulting in personalized families of preferences. We study the properties of the majority relation when defined on restricted domains that are the cartesian product of preference families, each one reflecting the corresponding agent’s objective indifferences, and otherwise allowing for all possible (strict) preference relations among alternatives. We present necessary and sufficient conditions on the preference domains of this type, guaranteeing that majority rule is quasi-transitive and thus the existence of Condorcet winners at any profile in the domain, and for any finite subset of alternatives. Finally, we compare our proposed restrictions with others in the literature, to conclude that they are independent of any previously discussed domain restriction.     

Effects of intensive longitudinal data collection on pregnancy and contraceptive use

We use an experiment based on the relationship dynamics and social life study of sexual behavior, pregnancy, and contraceptive use to investigate whether participation in weekly self-reports over one year result in differential effects on related behaviors and attitudes, compared to participation in a one-time follow-up interview requiring retrospective self-reporting for the prior year. We randomly assigned 200 subjects to either a control group or a journal group. All subjects were interviewed at the beginning of the study (baseline interview) and 12 months later (closeout interview). Subjects in the journal group also completed a five-minute web- or phone-based survey every week during the 12-month study period. We found no statistically significant difference in pregnancy rates across the two groups at closeout. Contrary to our expectation, the control group experienced a slightly larger increase in having ever used a contraceptive method, although this was mainly due to increases in the least effective methods, such as condoms and withdrawal. Respondents in the weekly interview group became slightly more positive toward childbearing in terms of one specific attitude measure, but not for the vast majority of measures. We conclude that intensive longitudinal data collection does not appear to have a large or consistent impact on respondents’ pregnancy, contraceptive use, or related attitudes, relative to the more standard longitudinal approach.     

Gender Differences in Silencing Following Childhood Sexual Abuse

ABSTRACT

The clinical literature commonly asserts that males are less likely than females to disclose child sexual abuse at the time it occurs and take longer to discuss their experiences. These hypotheses were tested in this study. This study included 145 men and 151 women. Participants were asked about disclosure at the time of the abuse and the length of time it took for them to discuss the experience. Comparison across these two studies found that boys were significantly less likely than girls to disclose the abuse at the time it occurred and also took significantly longer to discuss their childhood experiences later in life.     

Automatic selective intervention in dynamic linear models

In this paper we propose an algorithm to carry out the monitoring and retrospective intervention process in Dynamic Linear Models, both selectively and automatically. The algorithm is illustrated by analysing several series taken from the literature, in which the proposed procedure is shown to perform better than the scheme proposed by West & Harrison (1997, Chapter 11).     

Editorial

Abstract

The Publications Committee consists of six members. Each member of the Committee will be invited to provide a guest editorial, to introduce the Committee members to the readership. The editorial will have the rubic of Publications and the AASW'. The editorial will introduce the readership to the views and beliefs of individual Committee members in relation to publications; as such it will not necessarily reflect AASW publication policy. We begin with Dr. Jim Barber.

OVER five years ago now, the Board of Directors commissioned me to conduct a review of Australian Social Workand to canvass the options for change at the November 1995 Board meeting in Canberra. I was told that there had been persistent complaints within some branches about the quality of the journal and its relevance to the membership at large.     

Attachment and adaptive skills in children of international adoption

The attachment pattern of a sample of 168 internationally adopted children was explored in this study using the semi‐structured Friends and Family Interview. The pattern was analysed in relation to the development of adaptive skills as an expression of the children's resilience. The secure attachment pattern rates were slightly lower and the insecure attachment patterns were considerably higher than those of normative samples from the previous studies. The children from Eastern Europe demonstrated a more insecure attachment pattern (odds ratio [OR]= 2.46; confidence interval [CI]= 1.23–3.94), and their scores on the adaptive skills scales were lower than the scores of children from other countries (OR = 2.62; 95% CI = 1.02–6.72). These results help to identify the groups at risk of failing to develop secure attachment patterns and appropriate adaptive skills, and should provide valuable information for designing effective interventions.     

Spurious Instrumental Variables

Spurious regression phenomenon has been recognized for a wide range of Data Generating Processes: driftless unit roots, unit roots with drift, long memory, trend and broken-trend stationarity, etc. The usual framework is Ordinary Least Squares. We show that the spurious phenomenon also occurs in Instrumental Variables estimation when using non stationary variables, whether the non stationarity component is stochastic or deterministic. Finite sample evidence supports the asymptotic results.
