A Longitudinal Evaluation of the Ogden City Head Start Program

This study attempted to investigate the differences in the Head Start population of the Ogden City Schools and to determine if the differences had a significant influence on ability comparisons. An attempt was also made to evaluate the longitudinal benefits of Head Start training. The original data was collected in the 1966-67 evaluation of the Head Start program. Additional data was collected as this original group of Head Start children progressed through kindergarten, first, and second grades. Variables considered in this study were, residence, age, sex, socio-economic deprivation, family constellation, and ethnic group. In addition, a comparison was made of children in kindergarten, first, and second grades, who had Head Start, to peers who had no Head Start experience. The variables were tested by analysis of variance and chi-square. Results of the analyses of data revealed that significant differences existed in the following categories: residence, socio-economic deprivation, ethnic groups, kindergarten, and first grade. The difference in residence support the Ogden City Schools labeling the target area as a impoverished part of the district that needs additional services, The criteria of family income or socio-economic deprivation is a justifiable measure to use in determining who should be admitted to the Head Start program. It was also determined that the minority ethnic groups made the most gain s in the Head Start program with the order of gain being Negro, Spanish American and Caucasian. It was also concluded that the children who had received the Head Start experience were able to maintain their gains through the first grade. School apparently has a gradual ameliorating influence however as the differences between second graders who had Head Start and matched peers who did not have Head Start were no longer significant

High-throughput gene discovery in the rat

The rat is an important animal model for human diseases and is widely used in physiology. In this article we present a new strategy for gene discovery based on the production of ESTs from serially subtracted and normalized cDNA libraries, and we describe its application for the development of a comprehensive nonredundant collection of rat ESTs. Our new strategy appears to yield substantially more EST clusters per ESTs sequenced than do previous approaches that did not use serial subtraction. However, multiple rounds of library subtraction resulted in high frequencies of otherwise rare internally primed cDNAs, defining the limits of this powerful approach. To date, we have generated >200,000 3′ ESTs from >100 cDNA libraries representing a wide range of tissues and developmental stages of the laboratory rat. Most importantly, we have contributed to ∼50,000 rat UniGene clusters. We have identified, arrayed, and derived 5′ ESTs from >30,000 unique rat cDNA clones. Complete information, including radiation hybrid mapping data, is also maintained locally at http://genome.uiowa.edu/clcg.html. All of the sequences described in this article have been submitted to the dbEST division of the NCBI
