Effectiveness of a Transitional First Grade ProgramDay, Mary Jo, 1940- 12 1900 (has links)
The purpose of this study was to determine the effectiveness of a transitional first grade program. A comparison of reading and math achievement and school attitude was the focus of the study. The study utilized a pretest/posttest design. The group of regular first grade students who qualified for the transitional program but attended regular first grade was the control group. The group of transitional first grade students was the experimental group. The regular first grade students received formal instruction in all academic areas. The experimental group received no formal instruction. All students were pretested and posttested using the Iowa Test of Basic Skills and the Minnesota School Attitude Survey. Testing was administered to small groups of five or less by the researcher. Scoring was done also by the researcher. An analysis of covariance was used to determine if a significant difference existed between the groups. The analysis of covariance did not produce a significant F at the .05 level when applied to the Iowa Test of Basic Skills except for reading for boys in both groups. The numbers in each cell were low and no further comparisons were made. Due to a testing date that was approved late in the year, the Minnesota School Attitude Survey was determined to be invalid. Scores are reported for the reader's perusal only.

Identifying Genetic Factors and Processes Involved in the Cardiac Perinatal Transitional ProgramKouri, Lara 03 May 2011 (has links)
Cardiomyocyte perinatal development is characterized by the transition from a hyperplastic to a hypertrophic growth. We hypothesize that genetic factors and processes in the cardiac perinatal transitional program can be identified by a systematic analysis of different stages in heart development. Microarray expression patterning of mRNAs and microRNAs uncovered a perinatal cardiogenomic switch between 5 and 7 days post-birth. Gene ontology analysis revealed cellular and metabolic processes as highly representative Biological Processes. Moreover, approximately 40% of known mice transcription factors are significantly (p<0.05) fluctuating between embryonic day 19 and 10 days post-birth. As the heart matures, cardiomyocytes progressively exit cell cycle with day 5 as a pivotal point. Hypertrophy entails cardiomyocyte binucleation which may be promoted by Protein Regulator of Cytokinesis (Prc1) and its interactors. Temporal cardiac transcription expression analysis provides insight into underlining effectors within the cardiac perinatal transitional program as well as cardiac pathology.
