Adult children of parents with mental illness: navigating stigma

The experiences of children who live with parental mental illness are becoming increasingly recognized. However, there remains a limited body of knowledge in relation to an individual's longer term experiences. This study sought adult children's experiences of childhood parental mental illness. It generated reflections of 13 adult children who had lived with parents with mental illness during their childhood. The narrative design of the study facilitated a voice for participants. The paper presents one main theme of the findings. The findings offer a unique insight into childhood awareness of social stigmas and children's behavioural changes to avoid disclosure of parental mental illness. Participants noted that they were aware of social stigmas associated with mental illness during their childhood. This contributed to their fear of disclosure to others that fuelled a culture of familial secrecy, reinforcing the children's own sense of difference. Further work is required to enhance community understanding about the familial journeys of parental mental illness and the impact of negative‐natured stigmas.     

Employment-Based Training on Alcohol and Other Drugs in England: Bridging the Gap

The first of its kind in England, this study explored the extent and nature of employer-based training on alcohol and other drugs for social workers working in children's and adults' services. A national survey of workforce development departments was undertaken to find out how social workers are being prepared by their employers for engaging with people who use alcohol and other drugs. Based on a response rate of 46%, the findings show that a majority of departments (82%) provided training on these issues in the year 2011–2012. However, most of this training was not mandatory. These courses are targeted most often at those working in children's services rather than those in adults' services. Most courses are offered at basic or intermediary level, and content of training is covered inconsistently. These findings suggest a need to increase the priority of alcohol and other drugs' training across adults' services in particular and to make this training mandatory, as well as ensuring that staff have adequate time and incentive to attend. Effectiveness of social care practice for all social care practitioners around alcohol and other drugs use could be improved with more focus on training practitioners how to talk to service users about their substance use.     

Preventing the Importation of Illicit Nuclear Materials in Shipping Containers

We develop a mathematical model to find the optimal inspection strategy for detecting a nuclear weapon (or nuclear material to make a weapon) from being smuggled into the United States in a shipping container, subject to constraints of port congestion and an overall budget. We consider an 11-layer security system consisting of shipper certification, container seals, and a targeting software system, followed by passive (neutron and gamma), active (gamma radiography), and manual testing at overseas and domestic ports. Currently implemented policies achieve a low detection probability, and improved security requires passive and active testing of trusted containers and manually opening containers that cannot be penetrated by radiography. The annual cost of achieving a high detection probability of a plutonium weapon using existing equipment in traditional ways is roughly several billion dollars if testing is done domestically, and is approximately five times higher if testing is performed overseas. Our results suggest that employing high-energy x-ray radiography and elongating the passive neutron tests at overseas ports may provide significant cost savings, and several developing technologies, radiation sensors inside containers and tamper-resistant electronic seals, should be pursued aggressively. Further effort is critically needed to develop a practical neutron interrogation scheme that reliably detects moderately shielded, highly enriched uranium.     

The relationship between newcomer expectations of job stressors and adjustment to the new job

This study examined the relationship between unrealistic expectations of organizational newcomers regarding job stressors and subsequent adjustment to the new job. Using a sample of 91 new employees, measures of expected stressors (gathered prior to the first day of work) were compared with stressors reported after six months on the job. The study examined the relationship between the accuracy of expected stressors (demands) and three indicators of job adjustment: job satisfaction; job involvement; and distress symptoms. The results provided partial support for the hypothesis that newcomers who underestimate job stressors have more difficulty adjusting on the new job than do newcomers who overestimate job stressors.     

Judgments about personal identity in childhood and adolescence

Judgments concerning personal identity were studied in children and adolescents. Each subject was asked to imagine entering a hypothetical machine which simultaneously produced two persons, with each person receiving one of four sets of the subject's characteristics: physical, active, social, or psychological. Subjects were asked to judge which of the resulting persons was most nearly identical with the self. Results from the first study with middle-class Americans demonstrated that the social characteristics are most frequently chosen by young adolescents. With age, the physical characteristics were less frequently selected and the psychological characteristics were more often selected. In Study 2, middle-class American children between the ages of 6 to 7 judged the psychological characteristics of self most important in preserving identity, even though their self-concepts as elicited by other methods appeared physicalistic. The results are discussed in terms of their implications for accounts of self-concept development.
