Serving low-income children from birth to age five and their families, Head Start is a primary venue for identification and intervention in the area of child mental health. However, recent research has demonstrated that the knowledge base regarding prevalence, developmental course, and predictive power of child mental health problems is lacking for young children in general and low-income, diverse populations in particular. Head Start's agency-level data is often discrepant from both national estimates and small, intensive studies of similar populations, perhaps for reasons related to availability of community services and professional staff, as well as concerns about stigmatization. Following on recent expert recommendations, new collaborative Federal initiatives are underway to increase our understanding of the types, trajectories, and treatments of mental health problems affecting the vulnerable children served by Head Start. The paper concludes with a call to action for the field in the area of young children's mental health. 相似文献

That the sample mean and variance are “good” estimates of the corresponding population parameters is easily accepted as “obvious” by students, but the concept of standard error of the mean is often found to be quite a hurdle. That this standard error decreases inversely as the square-root of the sample size, and the mysterious appearance of the Normal distribution, are often taken as magical and incomprehensible effects, and non-mathematical students can often be turned away from further understanding. This article describes a program which provides an experimental framework in which the student can rapidly develop an intuition for the basic properties of sampling. 相似文献

Erber (1988) has claimed that one of the reasons for the ascendancy of hearing aids has been the loss of confidence in speechreading. Speechreading can be of value to those suffering from presbyacusis and other hearing disorders, in augmenting hearing aids and cochlear implants, for large numbers of people in developing countries who are unable to afford electronic aids, and for those in advanced countries who are reluctant to wear an aid. I discuss the structure and the optimization of speechreading. New methods to optimize natural speechreading skills are required that must be based on the structure and nature of speechreading. It has been suggested that speechreading is, to some extent, innate, and so 'hard-wired', which would mean that the effect of long-term training is limited. I critique this view and present a macro-analysis of the experimental literature. I suggest that the innate view may be somewhat overstated. 相似文献

The nexus between college choice and persistence 总被引:2,自引:3,他引:2

Initial student commitments have long been considered an influence on persistence, but the reasons why students choose to attend a college have seldom been considered as dimensions of initial commitments that could influence persistence processes and outcomes. This study used NPSAS-87 to examine the influence of finance-related reasons for choosing a college on persistence decisions. The findings include (1) finance-related choices have direct and indirect influences on whether students persist in college; and (2) market-based, monetary measures of financial aid, tuition costs, housing costs, and other living costs have a substantial direct effect on persistence. 相似文献
