Integrating Software into PRA: A Software-Related Failure Mode Taxonomy

Probabilistic risk assessment is a methodology to assess the probability of failure or success of a mission. Results provided by the risk assessment methodology are used to make decisions concerning choice of upgrades, scheduling of maintenance, decision to launch, etc. However, current PRA neglects the contribution of software to the risk of failure of the mission. Our research has developed a methodology to account for the impact of software to system failure. This article focuses on an element of the approach: a comprehensive taxonomy of software-related failure modes. Application of the taxonomy is discussed in this article. A validation of the taxonomy and conclusions drawn from this validation effort are described. Future research is also summarized.     

A comparison of two programmes for victims of child sexual abuse: a treatment outcome study

This study aimed to evaluate the comparative effectiveness of individual therapy and combined individual and group therapy in the treatment of the psychological sequelae of child sexual abuse. The Child Behaviour Checklist (CBCL), the Youth Self Report form (YSR), the Children's Depression Inventory (CDI) and the Trauma Symptom Checklist for Children (TSCC) were administered before treatment and 6 months later to a group of 20 young people who participated in individual therapy (IT) programmes and to a group of 18 young people who participated in programmes that involved combined individual and group therapy (IGT). For both types of programmes, statistically significant improvement occurred on the following scales: the total problems, internalizing problems, externalizing problems, withdrawn, somatic complaints, anxious/depressed, social problems, attention problems and aggressive behaviour problems CBCL scales; the total depression, interpersonal problems and anhedonia CDI scales; and the depression and anger TSCC scales. The only scale for which one therapy programme led to greater improvement than another was the CDI ineffectiveness scale. The IGT programme led to a reduction in the mean CDI ineffectiveness score, whereas a slight increase in the mean ineffectiveness score occurred in the IT group. There were no significant differences in the rates of clinically significant improvement associated with the two treatments and no major differences between cases who improved and those that did not improve over the course of therapy. From this study, it may be concluded that after 6 months, individual therapy and combined individual and group therapy were equally effective in the treatment of the psychological sequelae of child sexual abuse.

WAITING LIST CONTROLLED TRIAL OF COGNITIVE MARITAL THERAPY IN SEVERE MARITAL DISCORD

Forty-one couples with severe marital discord participated in a controlled trial conducted to evaluate whether a form of marital therapy that is designed to enhance marital intimacy through facilitating self-disclosure of personal constructs was effective. The study found that there was no spontaneous remission in marital discord in couples on a 10-week waiting list. Couples subjectively reported improvement as a consequence of participating in marital therapy, and couples in therapy and on the waiting list showed a significant reduction in symptoms of nonpsychotic emotional illness. There was a significant pattern of improvement for wives in the therapy group compared to the waiting list group, but no such effect for the husbands.     

Primary Age Children Excluded from School: A Multi Agency Focus for Concern

SUMMARY: Exclusion from school is only one of a number of sometimes complicated and often inter-related reasons why children are not attending school Much of the focus of research and debate about exclusions has been about secondary age pupils. This paper begins to raise some of the issues that may make primary age exclusions a particular focus of concern and one that should reach and be addressed by a variety of agencies. The paper draws on research recently completed at the SSRIU (Social Services Research and Information Unit), University of Portsmouth, and is informed by an ESRC funded project in progress, which is investigating primary age exclusions at a national level.     

Treatment of an acting-out adolescent girl: An interpersonal experience

The current emphasis on psychotherapy as an interpersonal or intersubjective experience is highly relevant to clinical work with adolescents. This paper presentes and discusses the treatment of an acting out adolescent girl from the perspective of the two-person relationship, emphasizing the interaction between the patient's dynamics and the therapist's responses.     

Chemical Health Effects Assessment Methodology for Airborne Contaminants

Chemical Health Effects Assessment Methodology (CHEM) is a new procedure for assessing hazardous properties of airborne toxic contaminants. CHEM evaluates substances for four major health effect categories: carcinogenicity, mutagenicity, reproductive/developmental toxicity, and toxic effects other than the first three. Three elements are considered in the assessment: weight of evidence, potency, and severity of effect. This approach produces a profile of toxic properties of chemicals which preserves their unique multidimensional character and highlights data gaps.     

Guilt: A Factor in Sexual Satisfaction*

As individuals begin to engage in sexual activities, they must contend with the interaction of their current behaviors with any prior learning related to sexual guilt. While guilt feelings associated with participation in masturbation, petting, and sexual intercourse have decreased in recent years, especially among females, few studies have considered the role of guilt in sexual satisfaction among adolescent/young adults. In order to examine the relationship of guilt to psychological and physiological sexual satisfaction, a survey research design was employed utilizing the responses of coitally active male and female never-married students from a state university. Findings indicate that feelings of guilt about various sexual activities do affect sexual satisfaction with differential influences for males and females.     

Predicting Individual Differences in Recall by Infants Born Preterm and Full Term

A heterogeneous sample of infants with preterm histories and infants born full term participated in a study of declarative memory and rate of encoding, as measured in an imitation task and an examining task, respectively. Here we report the comparisons of the performances of infants born very preterm (27–34 weeks gestation) and moderately preterm (35–37 weeks gestation) to infants born full term (38–41 weeks gestation) and tested at 12 months corrected age (from due date). Lower levels of recall were seen among the infants born very preterm. Rate of encoding, weeks gestation, and score on the Mental Development Index (MDI) of the Bayley Scales of Infant Development were tested as possible sources of individual differences in recall. Rate of encoding and MDI predicted delayed ordered recall. Implications for early detection of cognitive difficulties in children with preterm histories are discussed.
