1	Can Headstart Programs Truly be Effective? Genetic Assessment of Cyclura Collei, The Headstarted Jamaican Iguana Rasberry, Armed Baba 09 May 2015 (has links) Headstarting is one of the more recent practices being used to maintain endangered populations in the wild. A headstart program was developed for the Jamaican iguana, Cyclura collei, in 1991 after its rediscovery in 1990. This current study tests the hypothesis that this population is experiencing a reduction in effective population size in spite of an increasing census population size due to the small number of nests available in the early years of the headstart program. A total of 875 individuals collected from 1991 to 2011 were genotyped at twelve variable microsatellite loci. Results from this study indicate a slight but significant decline in genetic variation (3% loss), and a modest proportional reduction in effective population size (0.075), since the initiation of the program. However, it is important to note these data also suggests that effective population size of this population is stabilizing. effective population Cyclura collei headstart
2	The Preschool Child's Knowledge of Musical Pitch Nelson, Farol Ann 01 May 1976 (has links) The objective of this study was to determine what kinds of musical instruments were most effective in developing pitch discrimination in preschool children. Five melody instruments were used in this study, including a wooden soprano recorder, a C flute, a commercially made xylophone, a melodica, and a set of cut conduit pipes played as a xylophone-type instrument. Children from the Child Development Labs at Utah State University, Logan, Utah comprised the sample. It was found that children do identify high and low pitches more easily in some instruments than in others. They discriminated between high and low pitches of the wooden soprano recorder more accurately than was true of any of the other four instruments, and were lea s t accurate in their response to the xylophone. There were no significant differences between responses of boys and girls. It was also found that the child had to possess a directional knowledge of high and low before he could identify high and low pitch. It was concluded that the recorder was a more effective instrument in teaching children to discriminate between high and low pitches than any of the other four instruments tested. verbal memory preschool indian headstart children Education

4	A genetic assessment of the Blue Iguana Recovery Programme’s success, and prognosis for the species’ future conservation McKinney, Mallory 07 August 2020 (has links) In this study, we used ostensibly neutral microsatellite markers to study genetic variance and heterozygosity of endangered Cyclura lewisi during captive management in the Blue Iguana Recovery Programme. We assessed the variation present in the founding population and how genetic diversity changed throughout the past 20 years of management. We also studied how heterozygosity may correlate with fitness through morphometric measures and success of recruitment after release into the wild. While we found a reduction in effective population size, standardized heterozygosity, and fixation indices did not significantly change from the founders to later generations. We found no evidence for inbreeding depression in the captive population but a significant difference in heterozygosity of animals released to the Salina Reserve. Lastly, we found little evidence to support heterozygosityitness correlations using morphometric measures. Genetics conservation cyclura headstart iguana reintroduction
5	Verbal Memory of Preschool Indian and Non/Indian Headstart Children Carter, Karen L. Swenson 01 May 1976 (has links) The purpose of this study was to test the hypotheses l) there is a significant difference between scores of Head Start children on the Uintah and Ouray Indian Reservation in Utah and the norms of the Verbal Memory Test from the McCarthy Scales of Children's Abilities; 2) there will not be an association between being Indian or non-Indian ; 3 ) there will be an association between teaching styles and the children's performance on the language test. The T test was used to analyze all of the data. The experimental sample scored lower, but not significantly lower than the standardized norms. There was no difference between Indians and non-Indians. The sample (N = 46 children; 30 boys and 16 girls) was taken from four classrooms which were compared with one another. There was a significant difference between classroom 1 and classroom 4 at the .01 level, supporting the hypothesis that there will be an association between teaching styles and language performance. When comparing boys to girls within the sample, girls did significantly better at the .02 level. verbal memory preschool indian headstart children Social and Behavioral Sciences
