Young children who enter foster care experience disruptions in care and maltreatment at a point when maintaining attachment relationships is a key, biologically based task. In previous research, we have found that young children experience challenges as they form attachments with new caregivers. They tend to push their new caregivers away, even though such children are especially in need of nurturing care. Further, many caregivers do not respond in nurturing ways when their children are distressed, which we have found is problematic for young children in foster care. We developed an intervention that is designed to help caregivers provide nurturance even when children do not elicit it, and even when it does not come naturally to them. This paper presents preliminary findings of the effectiveness of this intervention on children’s attachment behaviors. Forty-six children were randomly assigned to either the experimental intervention or to an educational intervention. For three consecutive days, attachment behaviors were reported across three distress-eliciting situations. Children whose parents had received the experimental intervention showed significantly less avoidance than children whose parents had received the educational intervention. These preliminary results suggest that the intervention is successful in helping children develop trusting relationships with new caregivers.  相似文献

Few after‐school programs target alcohol and other drug (AOD) use because it is difficult to encourage a diverse group of youth to voluntarily attend. The current study describes CHOICE, a voluntary after‐school program which targeted AOD use among middle school students. Over 4,000 students across eight schools completed surveys and 15% participated in CHOICE. Analyses indicated that there were some differences between CHOICE participants and nonparticipants. For example, African American and multiethnic students were more likely to attend. Past month alcohol users were more likely to initially attend, and marijuana users were more likely to continue attendance. Thus, CHOICE reached students of different racial and ethnic groups and attracted higher risk youth who may not typically obtain prevention services.  相似文献

This article extends symbolic interactionist thought on authenticity and stigma allure into the context of higher education in the United States where the status of the humanities is contested. Our abductive analysis of twenty‐nine, semistructured interviews with undergraduates at an elite university reveals that selecting a humanities major has social costs. Yet the students who opt into these majors renegotiate ideologies, practices, and resources in ways that generate meaningful educational experiences. Navigating these problematic situations in which status is threatened enables the social production and personal aesthetic experience of authenticity. These findings add a new evidentiary basis to theory on stigma allure and, in doing so, demonstrate that when rhetorics of crisis collide with the late modern quest for authenticity voluntary stigma can become a powerful, if also unwieldy, resource.  相似文献

In this paper, we develop an optimization model for efficiently scheduling internal audits of multiple units within a business enterprise. The model determines an optimal mix of audit frequencies for the audit units given the risks and costs involved in the audit process. We also show one method for estimating the audit cost and loss functions needed as input to the model and demonstrate how to obtain a solution for the model. To illustrate the model's use, we solve a sample problem with eight audit units and examine the sensitivity of the solution to misestimation of the risk parameters. Our results indicate that the model is readily solvable on a personal computer, useful for choosing an efficient mix of audit frequencies and an overall audit budget, and relatively insensitive to misestimation of the risk parameters.  相似文献
