A systematic review of psychosocial interventions for suicidal adolescents

Suicide is a leading cause of death for young people and rates of serious suicidal thoughts are even higher. Due to these high rates and potential harm to youth, effective interventions are necessary. The purpose of this systematic review was to determine the impact of interventions designed for suicidal adolescents. Both quasi-experimental and experimental designs in the published and unpublished literature were included, and a total of 17 studies were located. According to meta-analysis, intervention group participants were slightly less likely to have suicidal and self-harm events than control group participants. However, when studies assessed outcome at a later period than immediately after intervention, experimental group participants were slightly more likely to have suicidal and self-harm events than control group participants. For studies that measured suicidal ideation at posttest, intervention group participants were slightly less likely to report suicidal ideation than control group participants, both at posttest and at follow-up. These contradictory findings are explored and discussed.     

Managing Perishables with Time and Temperature History

We address the use and value of time and temperature information to manage perishables in the context of a retailer that sells a random lifetime product subject to stochastic demand and lost sales. The product's lifetime is largely determined by the temperature history and the flow time through the supply chain. We compare the case in which information on flow time and temperature history is available and used for inventory management to a base case in which such information is not available. We formulate the two cases as Markov Decision Processes and evaluate the value of information through an extensive simulation using representative, real world supply chain parameters.     

Competition and Wage Discrimination: The Effects of Interindustry Concentration and Import Penetration*

Objective. Economic theory suggests that competition reduces employers' latitude to engage in wage discrimination ( Becker, 1957 ). This study investigates the impact of foreign and domestic competition on wage discrimination. Method. Utilizing the sample of males in U.S. manufacturing industries from the 1990 Public Use Micro Sample (PUMS), industry wage equations are estimated. In a second stage, the impact of domestic and foreign competition on racial wage disparity is assessed. Results. We find little evidence to support our hypothesis. Conclusions. Notwithstanding, the failure of conventional economic theory to satisfactorily explain racial wage disparity reiterates the need to incorporate alternative theories of discrimination into mainstream economic theory.     

Variable subset selection for optimal regression prediction at a specified point

It is often desirable to select a subset of regression variables so as to maximise the accuracy of prediction at a pre-specified point. There are a variety of possible mean-square-error-type criteria which could be used to measure the accuracy of prediction and hence to select an optimal subset. We shall show how these can easily be included in existing stepwise regression codes. The performance of the criteria is compared on a data set, where it becomes obvious that not only do different criteria give rise to different subsets at the same prediction point, but the same criterion quite commonly gives rise to different subsets at different prediction points. Thus the choice of a criterion has a major effect on the subset selected, and so requires conscious selection.     

Parent and Child Therapy: An Attachment‐Based Intervention for Children With Challenging Problems

Parent and Child Therapy (PACT) is an attachment‐based intervention for children aged between 4 and 12 years old experiencing emotional and behavioural problems. It is appropriate for distressed parent—child relationships which have not responded to systemic family therapy. PACT seeks to reframe parent—child relationship distress using narrative techniques and experiential tasks based on the concept of supported looking. Therapy occurs in parallel for parent and child using a one‐way screen. PACT improves parents' reflective capacity and sensitivity, and for the child's sense of security in her primary attachment relationship. An outline of the four stages of PACT is presented along with a case study to illustrate the course of PACT. Finally, we discuss the dissemination of PACT within a busy child and adolescent mental health service and outline our plans for future outcome evaluation.     

Clustering objects on subsets of attributes (with discussion)

Summary.  A new procedure is proposed for clustering attribute value data. When used in conjunction with conventional distance-based clustering algorithms this procedure encourages those algorithms to detect automatically subgroups of objects that preferentially cluster on subsets of the attribute variables rather than on all of them simultaneously. The relevant attribute subsets for each individual cluster can be different and partially (or completely) overlap with those of other clusters. Enhancements for increasing sensitivity for detecting especially low cardinality groups clustering on a small subset of variables are discussed. Applications in different domains, including gene expression arrays, are presented.     

Young Men as Victims and Perpetrators of Violence in Northern Ireland: A Qualitative Analysis

This article explores issues of masculinity and violence in the lives of young men in disadvantaged areas in Northern Ireland. Qualitative data were collected in four focus groups, one group of young men from the Catholic community, one group of young men from the Protestant community, one group of community representatives, and one group of Young Offenders ( N = 28). Themes were extracted from the data using a grounded approach. Results indicate that social disadvantage is fundamental to experiences of violence and that young men understand the costs and benefits of a masculine identity that incorporates a capacity for violence. Discussion suggests that initiatives to reduce violent behavior should be compatible with socially and culturally acceptable constructions of masculinity.
