Cochlear Implants And Executive Function In Children: A Current Review Of Literature, Jessica Bonezzi, Dr. Alex Meibos

We systematically reviewed existing research on cochlear implantation and executive function to determine if children with bilateral profound hearing loss with cochlear implantation have executive functioning levels similar to their normal hearing peers. Overall, we wanted to know if cochlear implantation resulted in executive functioning in deaf children. A systematic analysis of research was performed using the Preferred Reporting of Systematic Reviews and Meta-Analyses (PRISMA) technique. Research comparing unilaterally implanted children to bilaterally implanted children shows that bilaterally implanted children scored higher on verbal IQ tests. Research comparing predominately bilaterally implanted children to norms presents split results.

The dynamics of polymer thin films have been demonstrated to be significantly altered from the bulk, but the origins of such differences are not well defined. In this work, we seek to understand the differences in the structural dynamics (or physical aging) of polystyrene (PS) through branching and other well defined architectures (comb and centipede). The aging dynamics of ultrathin films (< 30 nm) differ from relatively thick films (100-150nm) with linear PS thin films aging more rapidly than the relatively “bulk-like” thick films. Ellipsometric measurements are used to characterize the physical aging rate of the films. The change in film thickness and refractive index as the films are held below the glass transition temperature (Tg) provides a simple measure of the physical aging. In this study, four different architectures (linear, comb, 4 arm star, and centipede) will be investigated. For each PS architecture, the aging rate will be determined for film …
