New Orleans Early Intervention Study of Children with Visual Impairments     

Diane Behl  Karl R. White  Colette M. Escobar 《Early education and development》1993,4(4):256-274

There is widespread agreement that early intervention for children with visual impairments and their families is important and beneficial. However, few con- trolled prospective studies of the effectiveness of various types of early intervention have been completed with these children. This randomized study evaluated the immediate and long-term effects of a comprehensive, weekly homebased intervention for infants and toddlers with visual impairments, compared with a low-intensity treatment through parent group meetings offered approximately 12 times per year. In annual assessments conducted for t h e years after the intervention was begun, there were negligible statistically significant or practical differences between groups based on a variety of measures of child and family functioning. In light of the cost-effectiveness analyses reported, questions are raised about the type of early intervention that should be provided to children with visual impairments.  相似文献   

Bullying,education and earnings: Evidence from the National Child Development Study     

Sarah Brown  Karl Taylor 《Economics of Education Review》2008

We explore the effect of bullying at school on the educational attainment of a sample of individuals drawn from the British National Child Development Study (NCDS). Our empirical findings suggest that school bullying has an adverse effect on human capital accumulation both at and beyond school. Moreover; the impact of bullying on educational attainment at age 16 is found to be similar in magnitude to class size effects. Furthermore, in contrast to class size effects, the adverse influence of bullying on educational attainment remains during adulthood. In addition, being bullied at school influences wages received during adulthood as well as indirectly influencing wages via educational attainment.  相似文献
