David: The first hour in the assessment and treatment of an adolescent

This paper presents an initial hour of therapy with 17 1/2 year old David, illustrating his distinctive experience, endowments, vulnerabilities and resiliencies. This first encounter permits a glimpse into typical adolescent conflicts and issues, how newer theoretical perspectives guide clinical thinking and technique, and the ways in which sociocultural forces intertwine with personal experience.in private practice.     

Genetic Contributions to Adolescents' Extrafamilial Social Interactions: Teachers, Best Friends, and Peers

The purpose of the present study was to investigate genetic and environmental contributions to individual differences in adolescents' social interactions outside the family. We investigated sibling resemblance for adolescents' reports of interactions with best friends and teachers, and parents' perceptions of adolescents' peer groups in 701 same-sex adolescent sibling pairs aged 10-18, using a twin, full sibling, and step sibling design. Our goals were to assess the magnitude of sibling resemblance, and to disentangle resemblance due to shared genetic heritage from that due to shared environmental experiences. Substantial genetic influence was found for parents' perceptions of adolescents' peer groups. Adolescents' reports of positive interactions with teachers and best friends also showed significant genetic influence. In contrast, individual differences in adolescents' reports of negative interactions with teachers and best friends showed no significant genetic influence. In addition, most environmental influences for social interactions with teachers, best friends, and peers were largely of the nonshared variety, suggesting that growing up in the same family does not make adolescents similar in their extrafamilial social interactions.     

Using the Summed Rank Cusum for monitoring environmental data from industrial processes

Environmental issues have become a hot topic recently, especially those surrounding industrial outputs. Effluents, emissions, outflows, by-products, waste materials, product de-commissioning, land reclamation and energy consumption are all the subject of monitoring, either under new legislation or through economic necessity. Many types of environmental data are often difficult to understand or measure because of their unusual distribution of values however. Standard methods of monitoring these data types often fail or are unwieldy. The scarcity of events, small volume measurements and the unusual time scales sometimes involved add to the complexity of the task. One recently developed monitoring technique is the Summed Rank Cusum (SRC) that applies non-parametric methods to a standard chart. The SRC can be used diagnostically and this paper describes the application of this new tool to three data sets, each derived from a different problem area. These are measuring industrial effluent, assessing the levels of potentially harmful proteins produced by an industrial process and industrial land reclamation in the face of harmful waste materials. The use of the SRC to spot change points in time retrospectively is described. The paper also shows the use of SRC in the significant-difference testing mode, which is applied via the use of spreadsheets. Links to other similar methods described in the literature are given and formulae describing the statistical nature of the transformation are shown. These practical demonstrations illustrate that the graphical interpretation of the method appears to help considerably in practice when trying to find time-series change points. The charts are an effective graphical retrospective monitoring technique when dealing with non-normal data. The method is easy to apply and may help considerably in dealing with environmental data in the industrial setting when standard methods are not appropriate. Further work is continuing on the more theoretical aspects of the method.     

Six Sigma: an opportunity for statistics and for statisticians

Six Sigma is the name given to one of the most widely used methodologies for improving efficiency and profitability in manufacturing and production processes. Its users are trained in the basics of statistics, problem solving and project management. Shirley Coleman tells us that Six Sigma is an effective vehicle for introducing the statistics that have been available for years but have not been implemented.     

A Global Review of New Social Risks and Responses for Children and their Families

Given global demographic and social trends, the need for new policy and program responses is essential. This article identifies and describes new and traditional social risks affecting children and their families in both industrialized and developing countries by region. Traditional risks continue in the developing as well as the industrialized countries but the extent and scale are very different and the problems are far more severe in developing countries. In addition, new risks are now evident and new policy responses are emerging. Attention to the new risks is increasing, with growing investment in services and policies facilitating the reconciliation of work and family life and non-traditional families. The citizens of many developing countries experience new risks as well, but their capacity to confront and address these risks is also more limited.     

Welfare attitudes and social class: the case of Hong Kong in comparative perspective

Based on a survey of Hong Kong residents, this article explores the attitudes towards the welfare state and whether or not there are significant differences between different social classes with regard to their approval of the welfare state. The findings were then compared with those for Sweden and the USA. The study shows that Hong Kong residents strongly approve of the welfare state. The strength of their support is similar to that in Sweden and is far stronger than in the USA. In Hong Kong, the influence of social class on attitudes towards the welfare state is negligible. In some cases, the privileged classes expressed greater approval for the welfare state than the underprivileged classes. This is in striking contrast to the experiences in Sweden and the USA where the underprivileged classes are more supportive of the welfare state than are the privileged classes.     

Nurses' representations of the perceived causes of work-related stress: A network drawing approach

This paper reports a study, involving a network drawing approach, that examined how nurses perceive the interrelationship between causes of workplace stress. Network analysis originated in sociology as a method of examining the relationship between people, objects or events. It has recently been adapted to examine participants' perceptions of the relationships between causes of a phenomenon, either by asking participants to complete a grid rating the strength of all the possible links between causes or by getting them to draw a diagram of the links that they think are important. The network drawing technique, in which participants are asked to draw a diagram indicating perceived causal links between nominated causes of stress and also to indicate the strength of these links, was employed in this study. The causes of stress were taken from a previous study in which nurses kept a diary for one week detailing stressful events and their causes. There were 48 participants in the present study and the main results confirmed the importance of staffing levels and inadequate support as perceived direct causes of stress. The study also revealed the importance of indirect links between staffing levels and other causes of stress. The networks illustrate how direct and mediating causes of stress are connected and lie largely outside nurses' control. The results are discussed in relation to other recent work on the causes and experience of stress by nursing staff.
