Discovering parental drug dependence: silence and disclosure1

Children of drug dependent parents form a large and growing population at elevated risk of adverse developmental and social outcomes. In this study 36 children and young people described growing up in such families. Parents tried to shield children from exposure, however the majority of young people demonstrated a detailed awareness of their parents' problem with drugs whilst living with the parentally imposed fiction that drugs were not at the heart of their family dynamic. Children and young people are locked into a silence they find difficult to unburden to anyone. The policy imperative is recognition of the impact on children of living daily with parental drug dependence and means of ameliorating their living circumstances in ways that do not label them further.     

Between a ROC and a hard place: Teaching prevalence plots to understand real world biomarker performance in the clinic

The Receiver Operating Characteristic (ROC) curve and the Area Under the Curve (AUC) of the ROC curve are widely used in discovery to compare the performance of diagnostic and prognostic assays. The ROC curve has the advantage that it is independent of disease prevalence. However, in this note, we remind scientists and clinicians that the performance of an assay upon translation to the clinic is critically dependent upon that very same prevalence. Without an understanding of prevalence in the test population, even robust bioassays with excellent ROC characteristics may perform poorly in the clinic. While the exact prevalence in the target population is not always known, simple plots of candidate assay performance as a function of prevalence rate give a better understanding of the likely real‐world performance and a greater understanding of the likely impact of variation in that prevalence on translation to the clinic.     

An Ecological Approach to Understanding Youth Violence: The Mediating Role of Substance Use

The authors tested an ecological model that posits mediating variables (substance use and mental health) in the association between ecological factors (family closeness, school closeness, and peer closeness) and youth violence in a sample of 4,783 adolescents. Model including substance use present significantly less total effect between ecological factors and youth violence than do models without substance use. Additional probing of significant mediation effect using the Sobel test was performed and suggested that substance use did function as a mediator in the hypothesized path. Considerations of adolescent violence should recognize the possible role of ecological factors and how their influence may vary by substance use.     

Applying Process Knowledge for Yield Variation Reduction: A Longitudinal Field Study*

The widespread recognition of the detrimental effects of high yield variation in advanced manufacturing technology settings, both in terms of cost and management of production processes, underscores the need to develop effective strategies for reducing yield variation. In this article, we report the findings of a longitudinal field study in an electromechanical motor assembly plant where we examined how the application of process knowledge by production work teams can reduce yield variation. We propose and provide an operationalizion of a strategy to identify the sequence of particular types of actions—actions to control the mean followed by actions to control the variance—that work teams should pursue over time to apply process knowledge for reducing yield variation. The results of our empirical analysis show that yield variation was significantly reduced on three of the four production lines at the manufacturing plant that served as our research site. Differences in strategies for applying process knowledge help explain the different results on each of the production lines.     

The Life Rope: a transactional approach to exploring worker and life role development

The Model of Human Occupation offers a framework for analyzing occupational roles including that of worker; however, it does not describe the dynamics of role change after a traumatic injury. This paper reports a qualitative study of sixteen individuals who experienced a traumatic spinal cord injury in the midst of their occupational career development. The study examined their role change processes involved in redeveloping the worker role. Data were collected across 24 months of the participant's lives and triangulated via participant observations, guided interviews, mapping, and archival document review. Results showed that individuals formed multiple strands within their role repertoires at any point in time. After a traumatic injury, the worker role became an optional, elective role strand, one that often unraveled first as they encountered breakdowns in more basic survival roles, such as home manager, assistive technology user and attendant care employer. The metaphor of a Life Rope emerged as a useful conceptual framework for explaining life role development, including that of worker.     

Undocumented Latina immigrants in Orange County,California: a comparative analysis

"This article examines a unique data set randomly collected from Latinas (including 160 undocumented immigrants) and non-Hispanic white women in Orange County, California, including undocumented and documented Latina immigrants, Latina citizens, and non-Hispanic white women. Our survey suggests that undocumented Latinas are younger than documented Latinas, and immigrant Latinas are generally younger than U.S.-citizen Latinas and Anglo women. Undocumented and documented Latinas work in menial service sector jobs, often in domestic services. Most do not have job-related benefits such as medical insurance.... Despite their immigration status, undocumented Latina immigrants often viewed themselves as part of a community in the United States, which significantly influenced their intentions to stay in the United States. Contrary to much of the recent public policy debate over immigration, we did not find that social services influenced Latina immigrants' intentions to stay in the United States."     

最初·印象

1872年,一个名叫克劳德·莫奈的法国画家在勒阿弗尔港创作了一幅写生画,描绘的是港口的日出景象.因为日出的美丽转瞬即逝,莫奈为了追上太阳的脚步,只能大略描绘,因此作品显得粗糙与潦草.这种风格遭到了很多评论人士的鄙夷,一名新闻记者甚至讽刺这幅画是“对美与真实的否定,只能给人一种印象”.这幅画本来没有名字,正是因为有了这样一种评论的声音,莫奈干脆将画作命名为《日出·印象》.谁也没有料到,这幅画引申出了“印象派”这一新的艺术流派,并成了印象派的开山之作.     

Full-service community schools: a strategy--not a program

The concept that drives the emerging full-service community school movement is this: Schools cannot address all the problems and needs of disadvantaged children, youth, and families. Community schools are operated jointly by school systems and community agencies, are open extended hours, and may provide the site for after-school programs, primary-care health services, mental health counseling, parent education and involvement, and community development. No two community schools are alike. They grow out of a planning process that involves all stakeholders, school personnel, community-based organizations, city and county government, parents, and students. The Quitman Street Community School in Newark, New Jersey, exemplifies this approach.
