Parental substance abuse is a major factor in families experiencing foster care placement, yet little is known about the potential of screening in determining risk or identifying subpopulations for which elevated risk occurs. One Midwestern state recently implemented screening. This research uses information gathered as part of the screen's implementation to conduct a latent class analysis. The research was extended to provide a detailed examination of differences in child and family characteristics across classes, and to compare the screen results with caseworker impressions. Three distinct typologies emerged, with the high-risk and moderate-risk designations comprising only one quarter of the cases.  相似文献

This study examined longitudinal predictors of future eating problems in 435 female adolescents in Grades 7, 8, and 10, who were tested at two time points 8 months apart. Restrictive eating and bulimic tendencies were found to be relatively stable from Time 1 to Time 2, particularly in older grade levels. Partial correlations predicting Time 2 restrictive eating and bulimic tendencies indicated a role of body dissatisfaction, depression, and weight-related teasing, with findings being most clear in Grade 7. Path analyses indicated that the relationships among predictors were more complex and that some of the relationships were mediated by other variables.  相似文献

While the “achievement gap” generally and appropriately focuses upon gaps in test scores and other outcome measures, there may also be an “information gap” between higher and lower income parents that creates a disadvantage for lower income families in choosing good schools. In this article, we examine the extent to which there is such a gap, with a focus on data from a new survey of low‐ and moderate‐income parents who have made school choices. We find that, at least in relatively mature school choice environments like Milwaukee, Wisconsin, and Washington, DC, most low‐ and moderate‐income parents report being quite well informed and they engage in a variety of different activities to become informed. Thus, the information gap between lower and higher income parents may not be as large as scholars and policymakers had assumed. We do find that parents at the very lowest end of the income spectrum, especially those earning less than $10,000 per year, do feel less well‐informed and gather less information, but even here the differences are not enormous, relative to higher income parents.  相似文献

Airport Security, High Reliability, and the Problem of Rationality   总被引:2,自引:0,他引:2  
The events of September 11, 2001, have raised troubling questions regarding the reliability and security of American commercial air travel. This article applies the concepts and logic of high–reliability organizations to airport security operations. Contemporary decision theory is built on the logic of limited or buffered rationability and is based on the study of error–tolerant organizations. The concept of high–reliability organizations is based on the study of nearly error–free operations. For commercial air travel to be highly secure, there must be very high levels of technical competence and sustained performance; regular training; structure redundancy; collegial, decentralized authority patterns; processes that reward error discovery and correction; adequate and reliable funding; high mission valence; reliable and timely information; and protection from external interference in operations. These concepts are used to inform early–stage issues being faced by both local airports and the newly established Transportation Security Administration.  相似文献
