Theoretical Frameworks Used To Conceptualize The Intersection Of Deafness, Emotional/Behavioral Disabilities, And Language In The Literature: A Scoping Review, Jeremy M. Peterson

Theses and Dissertations

The prevalence rate for emotional/behavioral disabilities (EBD) among d/Deaf and hard of hearing (d/DHH) students has consistently been reported as statistically elevated in the literature, but the exact reason for this high prevalence has not been determined. Factors such as diagnostic shadowing, language proficiency, and difficulties in interfamilial communication have been identified; however, recent research suggests that language deprivation may also be a contributing factor. The intersection of language deprivation and EBD among d/DHH students has been studied by numerous researchers, but, to date, no one has explored how these topics are conceptualized together in the literature. As such, I …

A Word Is Worth A Thousand Words: Sustained Alphabetic Narratives And The Academic Success Of English Language Learners At The Secondary Level, Ricardo D. King Jr

Theses and Dissertations

In recent years, English Language Learner (EL) education, more commonly referred to as English as a Second Language (ESL) or Teaching English to Speakers of Other Languages (TESOL), has advocated for a multimodal approach to classroom instruction. At the same time, higher level English Language Arts (ELA) classes continue to use sustained alphabetic narratives without explicit references to multimodal practices (i.g., graphic novels, graphic narratives, comics, picture books, etc.). This disconnect in teacher advocacy and in educational practice has positioned EL students outside of the opportunities offered by higher level ELA coursework and the sustained alphabetic narratives that are taught …

Investigation Of The Human Temporal Styloid Process As A Bony Indicator Of Speech, Sommer A. Martin

Theses and Dissertations

The temporal styloid process in humans serves as an attachment point for the styloglossus, stylohyoid, and stylopharyngeus, which are involved in tongue movement and deglutition. I hypothesized that the length of the ossified styloid process in humans is the result of selection for increased musculature that would support tongue movements involved in speech. This hypothesis assumes that the relative length of the ossified temporal styloid process is unique to humans. A comparative analysis of the presence or absence of the temporal styloid process was conducted on ten genera of Old-World primates, and it was found that the length of this …

Beyond All Possible Doubt? The Shifting Of A Juror’S Conviction Threshold In Criminal Cases Based On Charge, Sentence, And Evidence, Sophie Johnson

Theses and Dissertations

In criminal trials, jurors must make a decision that will forever change the defendant’s life (Couloute & Kopf, 2018), during which jurors may consider the impact that not convicting a guilty person may have (i.e., Type II error) or if the charge is worth the crime regardless of the defendant’s guilt (i.e., Type I error). Jurors may raise their conviction thresholds if they feel a type II error is favorable to a type I error. Researchers have discovered that in cases where charge severity (e.g., Kerr, 1978) or the perceived sentence (e.g., Kaplan & Krupa, 1986) is higher, jurors shift …
