A Systematic Review To Assess The Use Of Peer Mediated Interventions For Children With Autism When Autistic Children Serve As Peer Instructors And Models, Corinne Boyce-Swem Aug 2025

A Systematic Review To Assess The Use Of Peer Mediated Interventions For Children With Autism When Autistic Children Serve As Peer Instructors And Models, Corinne Boyce-Swem

Seton Hall University Dissertations and Theses (ETDs)

Abstract

Autism spectrum disorder is a neurodevelopmental disorder characterized by deficits in social communication, social interactions and restricted, repetitive and stereotyped patterns of behavior, interest or activities. These deficits hinder autistic children’s social and communicative skills. Peer-mediated interventions (PMIs) have been found effective in the development of communication, play and social skills in individuals with ASD. In PMIs typically developing children are trained to be peer models of socially acceptable behavior for children with ASD. This however may contrast with literature indicating that the most effective peer models are individuals who share similarities with the learner. The current study was …

Numerical Evaluation Of A Novel Transpiration Cooling Scheme For Use In Dynamic Control Of Atmospheric Entry System, Caroline J. Anderson Aug 2025

Numerical Evaluation Of A Novel Transpiration Cooling Scheme For Use In Dynamic Control Of Atmospheric Entry System, Caroline J. Anderson

Graduate Thesis and Dissertation post-2024

Future space exploration missions require sustainable, efficient thermal protection systems for atmospheric entry, instead of disposable ablative shields. Transpiration cooling has interest as a long studied method but never used for missions to date, prompting further study to address concerns of flow transition downstream. In consideration of additional need for aerodynamic maneuvering for greater landing accuracy, a novel asymmetric scheme of transpiration cooling is presented as a method of using onboard coolant to meet entry trajectory maneuvering requirements. This numerical study creates a coupled model of vehicle-scale flow domain and material-scale thermal response to converge on accurate vehicle surface values.
