Assessment Of Visual Field Performance Asymmetries While Utilizing Aircraft Attitude Symbology, George A. Reis

Theses and Dissertations

Two experiments were conducted to examine visual performance asymmetries when perceiving complex, meaningful visual stimuli, such as the Arc Segment Attitude Reference (ASAR). The ASAR symbology represents an aircraft’s attitude. Experiment 1 examined participants’ performance while recalling and reporting various attitudes of ASAR symbology and a Gabor patch, which were briefly presented in the peripheral visual field. Performance was assessed for coordinate and categorical judgments at various display locations. The results were consistent with the horizontal-vertical anisotropy literature, which implies that performance would be better for stimuli placed on the horizontal meridian as compared to stimuli placed on the vertical …

The research questions that guided this study were: (1) To what extend was culturally relevant pedagogy practices happening in an early childhood dual-language classroom? (2) What is the level of an early childhood bilingual teacher’s knowledge of culturally relevant pedagogy? The findings in this study suggest that the teacher, who …

The Iconicity And Non-Arbitrariness Of Body Locations In Four Unrelated Sign Languages, John Samson

Theses and Dissertations

In this thesis, I show that universally, there is a strong tendency for signs located on the body to have an iconic or non-arbitrary motivation, especially in their original form. I analyze sign language dictionaries from four unrelated sign languages and establish an iconic or non-arbitrary link between the form of the signs and their meaning, and classify those links according to 8 categories of body location iconicity and 3 categories of non-arbitrariness. The strength of this tendency depends on the percentage of signs that are shown to have an iconic or non-arbitrary link. For the data analyzed here this …

Complex Predicates In Southern Turkmen: A Role And Reference Grammar Analysis, Nathaniel Andrew Shaver

Theses and Dissertations

This thesis uses the concepts of nexus and juncture, as articulated by Role and Reference Grammar, to examine complex verbal constructions found in four collected texts. These texts were collected from four Southern Turkmen (or Turkmen of Afghanistan) speakers. Through transcribing, glossing, and analyzing these texts, a number of complex predicates were identified. These were then described according to their various nexus juncture types. Three nexus juncture varieties were represented in the collected texts. These include clausal coordination, clausal subordination, and core cosubordination. Although not represented in the texts, it was possible to elicit three other provisional nexus juncture varieties. …

Klon Pronouns In Their Typological And Linguistic Context Within Wallacea, Eastern Indonesia, Johnny Marshel Banamtuan

Theses and Dissertations

Klon is a typologically SOV Timor-Alor-Pantar (Papuan) language, spoken by around 10,000 people on the islands of Alor and Pantar in eastern Indonesia. Like most SOV languages, Klon has postpositions, possessor before possessed, and sentence-final question particles. NPs are left-headed, with attributive modifiers, numerals, quantifiers, relative clauses, and demonstratives following the head noun. Klon has both pre-verbal and post-predicate verb modifiers. Preverbal modifiers can only modify verbal predicates. The language is aspect-prominent, with no grammatical tense. Like many SOV languages, Klon has clause-final standard negation, often occurring as bipartite negation.

Klon syntax pivots around the Undergoer. Only Undergoers are indexed …

Say Her Name: The Narrative Afterlives Of Breonna Taylor, Tyler S. Smith

Theses and Dissertations

Within the growing literature and media coverage of police misconduct and brutality, Black women and girls are functionally invisible. Since the Black Lives Matter movement began the names of only two women have stood out among the Black male victims we know by name: Sandra Bland and Breonna Taylor. Here, I will explore through a Black feminist analytic framework, how the intersectionalities of gender and race contributed to a delay in awareness and accountability for the death of Breonna Taylor. This content analysis looked at the media coverage of Breonna Taylor for the one-year period (3/13/20-3/13/21) to uncover the reasons, …

Automatic Short Answer Grading Using Deep Learning, Jinzhu Luo

Theses and Dissertations

Under the influence of the COVID-19 pandemic, traditional in-person teaching has undergone significant changes. Online courses become an essential education method. However, online teaching lacks adequate evaluation approaches. That's why exams are still indispensable. However, grading short answer exam questions can be an onerous task. In this work, we propose a novel Automatic Short Answer Grading (ASAG) model based on the Sentence BERT model. On the Short Answer Scoring V2.0 dataset, our proposed model shows improvements on accuracy, Marco F1 score, and Weighted F1 score comparing to the results obtained from the BERT model. In addition, we also compare different …

Auto-Detection Of Programming Code Vulnerabilities With Natural Language Processing, Yubai Zhang

Theses and Dissertations

Security vulnerabilities in source code are traditionally detected manually by software developers because there are no effective auto-detection tools. Current vulnerability detection tools require great human effort, and the results have flaws in many ways. However, deep learning models could be a solution to this problem for the following reasons: 1. Deep learning models are relatively accurate for text classification and text summarization for source code. 2. After being deployed on the cloud servers, the efficiency of deep learning based auto-detection could be much higher than human effort. Therefore, we developed two Natural Language Processing(NLP) models: the first one is …

A Community Cultural Wealth Perspective: Black And Latino Families' Experiences In Nyc Gifted Programs, Jennifer Cosme

Theses and Dissertations

Black and Latino K-12 students are largely underrepresented and underperform on standardized assessments in gifted programs compared to their White and Asian peers. The reasons for these differences in recruitment and retention of Black and Latino K-12 students have been attributed to a culturally biased admissions process and the lack of a culturally responsive curriculum framework for students of color. Nevertheless, a small minority of Black and Latino students are successful in K-12 gifted programs. Yet, little is understood about the factors that account for their success and the degree to which families are involved in their child’s success. Using …

Association Between The Beta Band Neural Response And The Behavioral Performance In Aphasic And Neurologically Intact Individuals, Yilun Zhang

Theses and Dissertations

The complex motor act of speech requires integrating linguistic and sensorimotor processes. Sensorimotor interaction mainly supports speech production in the form of state feedback control architecture. While speaking, subjects react to perturbations in the pitch of voice auditory feedback by changing their tone in the opposite direction to pitch-shift stimuli to compensate for the perceived pitch shift. Aphasia is a communication impairment affecting patients’ speaking, understanding, reading, and writing. The present study aims to examine the association between brain neural activity and the ability for speech auditory feedback error correction in both post-stroke aphasia and neurologically intact individuals. There are …

Operationalizing And Measuring High-Quality Instructional Practice – A Theoretical And Empirical Perspective, Genine L. Blue

Theses and Dissertations

This multiple manuscript dissertation offers a cohesive set of research studies curated to address three topics related to how high-quality instructional practice (HQIP) is defined, measured and ultimately connected to student engagement and achievement. Grounded in Benson’s (1998) framework of construct validation, this line of inquiry outlines (i) a well-articulated theoretical domain to make clear the substantive nature of HQIP as a multidimensional latent construct (e.g., substantive stage); (ii) the initial phases of an ongoing, iterative process consisting of empirical analyses designed to continuously build understanding around the structural nature of the observed variables selected to define construct’s empirical domain …

Secondary Administrators’ Perspectives On Their Involvement In And Barriers To Supporting Secondary Transition Programs For Students With Disabilities, Dottie H. Brown

Theses and Dissertations

To address disparities in post-school outcomes for students with disabilities, federal legislation mandates appropriate education programs to include transition planning and programs for students with disabilities. Because administrators are held responsible for ensuring appropriate educational programs for all learners including those with disabilities, it is important to understand their perspectives on secondary transition; however, research on administrators’ involvement in secondary transition activities is limited. Using a single-state survey, this study examined the perspectives of secondary school administrators on their involvement and engagement in providing effective transition programs and services for students with disabilities and their perceptions of barriers to providing …

The Criminalization Of Hiv And Hiv Stigma, Deanna Cann

Theses and Dissertations

In an effort to contain the HIV epidemic, lawmakers implemented various pieces of legislation across the United States, including laws that prohibit people living with HIV (PLHIV) from engaging in various behaviors without first disclosing their HIV-status. Public health scholars claim that this criminalization of HIV serves to increase stigma toward PLHIV, rather than prevent its transmission. Limited research has supported a connection between HIV exposure laws and increased stigma toward PLHIV. Still, researchers have yet to establish a causal relationship, and we know little regarding the mechanisms through which these laws serve to reproduce stigma. This study aims to …
