Family poverty, welfare reform, and child development

Our review of research suggests that family poverty has selective effects on child development. Most important for policy are indications that deep or persistent poverty early in childhood affects adversely the ability and achievement of children. Although the 1996 welfare reforms have spurred many welfare-to-work transitions, their time limits and, especially, sanctions are likely to deepen poverty among some families. We suggest ways policies might be aimed at preventing either economic deprivation itself or its effects.     

The pension subsidy of educational inequality

Public school teachers receive on retirement a pension typically equaling 75% of the average salary earned during the three peak years. While the teachers pay part of the costs of their defined benefit pension through payroll deductions, most of the cost is subsidized by the state. The pension subsidy, a far from neglible component of the per pupil cost of instruction, is particularly high in those school districts that pay high salaries and enjoy low student/teacher ratios. It is a regressive subsidy highly correlated with school district income and wealth. Several alternative reform measures are considered.     

Adolescents at risk for violence

Interpersonal violence among youth is a growing problem in many communities and schools across the nation. The causes of violence are multiple and complex. This paper examines the extent and nature of interpersonal violence among youth as well as the individual and societal factors which contribute to youth violence. Adolescents are disproportionately represented as both victims and perpetrators of fatal and nonfatal assaultive violence. Homicide rates among young men in the United States are vastly greater than those of other Western industrialized nations. Persons age 12–24 years face the highest risk of nonfatal violent victimization of any segment of our society. Arrest rates for homicide, rape, robbery, and aggravated assault peak among adolescents and young adults. Further, arrest rates for murder and other violent crimes have increased substantially among this age group since the mid-1980s. Effective prevention programs will require combinations of interventions aimed at multiple factors and delivered through many channels.     

Child sexual abuse: A study of prevalence in Great Britain

Of 2019 men and women (aged 15 years and over) interviewed as part of a MORI Survey of a nationally representative sample of Great Britain, 10% reported that they had been sexually abused before the age of 16 (12% of females; 8% of males). There was no increased risk associated with specific social class categories or area of residence. For all types of sexual abuse, the mean age of victims when first abused was significantly lower for females. Subjective reports of the effects of sexual abuse indicated that the majority (51%) felt harmed by the experience, while only 4% reported that it had improved the quality of their life. We estimate that there are over 4.5 million adults in Great Britain who were sexually abused as children, and that a potential 1,117,000 children will be sexually abused before they are 15 years of age. At least 143,000 of these will be abused within the family. The social and mental health implications are enormous, and the authors suggest that an effective intervention and prevention policy is urgently required.     

Concurrent and predictive validity of the Phelps Kindergarten Readiness Scale‐II

The purpose of this research was to establish the concurrent and predictive validity of the Phelps Kindergarten Readiness Scale, Second Edition (PKRS‐II; L. Phelps, 2003). Seventy‐four kindergarten students of diverse ethnic backgrounds enrolled in a northeastern suburban school participated in the study. The concurrent administration of the PKRS‐II and the Woodcock‐Johnson III Brief Intellectual Ability Scale (R.W. Woodcock, K.S. McGrew, & N. Mather, 2001a) occurred in the fall of the kindergarten year. To assess predictive validity, the Woodcock Johnson III Tests of Achievement (R.W. Woodcock, K.S. McGrew, & N. Mather, 2001b) was administered in the spring of that year. All concurrent and predictive correlations were significant. Based on the results of this study, the PKRS‐II may be used with confidence to screen for children who may be at risk for academic difficulties. © 2005 Wiley Periodicals, Inc.

Books: An Essential Part of Essential Libraries

As public libraries strive to remain essential parts of their communities in tough economic times, the centrality of books to the library's mission is explored.
