The Effects of Spanish-Language Background on Completed Schooling and Aptitude Test Scores

We investigate the effect of speaking Spanish at home as a child on completed schooling and aptitude test scores using data on Hispanics who grew up in the U.S. from the NLSY79. We model the accumulation of traditional human capital and English fluency, leading to the joint determination of schooling and test scores. We find that speaking Spanish at home reduces test scores but has no significant effect on completed schooling. The reduction in test scores is more dramatic the higher the education of the parents and when the choice of home language is endogenous.Hispanics, language, aptitude, ability, NLSY79

Evolutionary Development Study of Firebrat \u3ci\u3e(Thermobia domestica)\u3c/i\u3e

As most evolutionary development studies regarding wing origin take place using insects taxonomically closer to model organism, Drosophila melanogaster, there is a need of expanding studies to lower clades. While D. melanogaster is higher phylogenetically, basal clades would allow for a historical perspective of what occurs within the gene flow of conservative biomarkers. Further understanding of wings and flight would allow for a clearer understanding of how the migration of insects from sea to land has allowed them to become one of the most speciose taxa. Through the study of Thermobia Domestica, part of the Zygentoma, we expand on comprehension of biomarker conservation and developmental mechanisms within their embryology process. Developmental HOX genes analyzed include Distal-less, Wingless, Engrailed 1, Engrailed 2, and Ultrabithorax. Genes were sequenced at various developmental stages and used for further analysis through antibody staining and Fluorescent in-situ Hybridization. This study aids in expanding a new model organism within basal clades, while also gaining further genetic information on the novel structure, wings
