An Inference-Centric Approach To Natural Language Processing And Cognitive Modeling, Animesh Nighojkar

USF Tampa Graduate Theses and Dissertations

Reasoning over natural text is highly nuanced, and interpretations can vary widely depending on cultural background, financial status, age, gender, or even mood. This doctoral dissertation seeks to not only mimic human reasoning behaviors but also improve the task used in natural language processing (NLP) to capture naturalistic reasoning, known as the Natural Language Inference (NLI) task. NLI involves determining whether a hypothesis is true (entailment), false (contradiction), or indeterminate (neutral) based on a given premise. Initially, we will investigate the extent to which NLP systems designed to capture semantic equivalence actually measure meaning equivalence. After establishing that they do …

“Destiel Is Forever”: Negotiating Authenticity In The Cw’S Supernatural Family And Beyond, Hannah Lay

USF Tampa Graduate Theses and Dissertations

This dissertation examines the communicative constitution of authenticity and queerness. Because queerness has been policed and censored, notions of authenticity, in particular authentic queer representations, are fraught and sustaining to many LGBTQ+ and allied media consumers. The project focuses on the television series Supernatural—specifically, the unfolding of interactions in fan conventions, Twitter/X, and Tumblr involving celebrities and viewers of the series following a social breach, or rupture in the narrative. The last three episodes of Supernatural brought issues of queerness and authenticity to the fore for many viewers, making discussions about these themes compelling sites for multimodal data in the …

To bridge these gaps, we propose an IoT framework that ensures interoperability, seamless …

The Power Of Class Consciousness: An Investigation Of Permeability Beliefs, Dehumanization, And Evaluations Of The Poor, Kirsten J. Lee

USF Tampa Graduate Theses and Dissertations

Class consciousness, a theoretical construct from the Marxist tradition, promotes an understanding of class dynamics as a structural phenomenon. I hypothesized that class consciousness would moderate animalistic dehumanization of the poor. A total of 435 participants took an online survey containing self-report questionnaires. While a priori hypotheses related to animalistic dehumanization were not supported, exploratory analyses revealed that permeability beliefs—the degree to which an individual sees class boundaries as impermeable—moderate emotional tone when discussing the rich and the poor. Mirroring Marx’s theorizing, those with class consciousness spoke more positively of the poor and less favorably of the rich than their …

Music And Linguistic Semantic Anomalies: An Erp Study Of Integration And Expectancy On Predictive Processing Of Harmonic Music During A Self-Paced Reading Task, Jason Schmidt Avendaño

USF Tampa Graduate Theses and Dissertations

Music, like language, is widely known to communicate emotional meaning. Yet, much debate is still on whether musical information uses shared neural resources similar to language. Past experiments using only Reaction Time (RT) measures have found that when syntactic complexities in language coincide with harmonic music violations, enhanced processing difficulties suggest shared neurocognitive resources. However, researchers failed to find similar interactions in semantic word conditions. This experiment examined event-related potentials (ERPs) to index word recognition processes related to semantic expectancy generation (N400) and integration (LPC & FP) in musicians and nonmusicians. Unlike RT measures, ERP components allow us to understand …

Advancing Adversarial Audio: Human-In-The-Loop Black-Box Attacks, Rui Duan

USF Tampa Graduate Theses and Dissertations

Adversarial audio attacks pose significant security challenges to real-world audio applications. Attackers may manipulate speech to impersonate a speaker, gaining access to smart devices like Amazon Echo. In audio applications, there are two key areas: music and speech. In music, most attackers create a small noise-like perturbation on the original signal to evade copyright detection. However, this method degrades music's perceived quality for human listeners. In the speech, creating an adversarial example often requires many queries to the target model, a process too cumbersome for practical use in real-world scenarios, like interacting with smart devices numerous times.

In this dissertation, …

Enhancing Novice Teachers’ Social Justice Practices Through Critical Professional Learning: A Critical Participatory Action Research Study, Brianna C. Connors

USF Tampa Graduate Theses and Dissertations

There is a crucial need for social justice-oriented educators in today's classrooms given the growing population of America's multicultural student population. Social justice-oriented teacher preparation programs (TPPs) have contributed significantly to shaping the pedagogies of teacher candidates, better equipping them to serve all students. The transition period following teacher candidates' engagement in the TPPs, however, presents political, contextual, and personal challenges for novice teachers (NTs) dedicated to teaching for social justice. This research presents findings from a critical participatory action research (CPAR) study delving into the experiences of NTs engaged in critical professional learning (CPL). The purpose of this research …

Exploring The Enlightenment Function Of Thought Experiments: Unveiling An Underdeveloped Dimension Absent In Typologies, Dominique Greene-Sanders

USF Tampa Graduate Theses and Dissertations

Thought experiments (TEs) are imaginative tools used across various fields to explore theoretical and practical issues. This dissertation focuses on the application of TEs in ethics, specifically emphasizing the underdeveloped enlightenment function. The traditional use of TEs in ethics often aims to clarify, support, or refute specific claims through an argumentative structure. However, this work argues that TEs also play a key role in enhancing ethical competence by acknowledging the complexities of ethical dilemmas and fostering moral skills like critical thinking, moral reasoning, and ethical awareness through non-argumentative and non-theory-centric means.

The dissertation begins by explaining the nature and historical …

Essays On Machine Learning And Corporate Disclosure, Zicheng (Leo) Xiao

USF Tampa Graduate Theses and Dissertations

This dissertation contains two essays that shed new light on the dynamic of information disclosure on the capital market. For both two essays I leverage computational linguistics and 20 million turns of dialogues from earnings conference calls from 2006-2022. In the first essay, I introduce a novel measure that quantifies the disparity in narrative focus between managers’ disclosures and analysts’ questions during these calls, denoted as Topic Attention Divergence (TAD). A higher level of TAD indicates a higher level of firm-investor asymmetry and lower information quality. My results confirm that higher TAD in earnings conference calls inversely (positively) predict firms’ …

Uprooted, Displaced, Resilient: Kosovar Women’S Narratives Of Organizing For Survival During The Kosovo War, Erjona Gashi

USF Tampa Graduate Theses and Dissertations

The goal of this dissertation is to foreground Kosovar women’s narratives and organizing properties during the Kosovo War. I examine the overlooked gendered roles and day-to-day lived experiences of Kosovar women, survivors of the Serb genocide, political violence, and oppression, and investigate their organizing properties during the Kosovo War (1998-1999). In acknowledging women’s plurality of experiences and perspectives, I challenge the currently pervasive and monolithic narrative of women as passive victims of war present in scholarship in organizational communication and instead make overt the narrative of women as critical organizational actors that sustain lives during and after the war. Using …

Causes And Consequences Of Word Skipping During Reading: Evidence From The Co-Registration Of Eye Movements And Eeg, Sara Milligan

USF Tampa Graduate Theses and Dissertations

Skilled readers skip approximately one third of the words in the text while reading for comprehension (Rayner, 1998). Therefore, a prominent question for decades among reading and language researchers has been how people are able to recognize words and comprehend text without even looking at all of the words. Eye tracking studies have established that some information about an upcoming word in the text can be identified while still looking at the previous word (Rayner, 1975), but it remains an open question whether words that are skipped are thoroughly identified or if skipping decisions are based on shallow heuristic factors, …

Differences In Speech Patterns Produced By Spanish-English Language Learners During Single-Language And Mixed-Language Remote Academic Vocabulary Instruction, Ester Garcia

USF Tampa Graduate Theses and Dissertations

Individuals with lower proficiency in a second language tend to produce more disfluent speech patterns in the second language. Speech disfluencies refer to interruptions in the forward flow of speech and are distinct from the colloquial use of “fluency,” to characterize knowledge of a language. Prior research indicates that some speech disfluency patterns may be more common among Spanish-English bilingual children, who tend to produce more mazes (fragments of an utterance) and syllable repetitions than their monolingual peers. These patterns have been attributed to 1) acquiring a new language; 2) the influence of Spanish as a first language (L1) on …

Narrative Language Assessment And Intervention: Applications With Children With And Without Disabilities, Norah M. Almubark

USF Tampa Graduate Theses and Dissertations

Narrative is the art of conveying a sequence of causally and temporally linked events through monologic telling. Various functions can be served through narratives including sharing experiences, expressing ideas, providing entertainment, and imparting cultural or social values. Narrative language represents an authentic type of language that is useful for assessment and intervention because it can be analyzed according to content and form. The ability to use complex narrative language and produce quality narratives is associated with long-term academic and social benefits (Uccelli et al., 2019; Suggate et al, 2018). Given this crucial link, narrative language is suitable for child language …

Rate Of Latine Caregiver Involvement In The Well-Being Promotion Program Using Culturally And Linguistically Responsive Communication Practices, Nicole G. Pacateque Rodriguez

USF Tampa Graduate Theses and Dissertations

Latine and Hispanic youth tend to have higher rates of mental health disturbances in school compared to non-Latine youth, yet they are less likely to receive support (Alegría et al., 2008). Additionally, Latine families are more likely to terminate treatment for youth early due to negative stigma, lack of culturally appropriate mental health care, racial and ethnic discrimination, and linguistic and cultural barriers involving care (Kapke & Gerdes, 2016). Best practices in school-based mental health services often involve including caregivers in care (Hoover et al., 2019) as it can benefit outcomes of treatment for the child (Richards et al., 2007). …

“Manne, For Thy Loue Wolde I Not Lette”: Eucharistic Portrayals Of Caritas In Medieval And Early Modern English Literature And Drama 1350-1650, Rachel Tanski

USF Tampa Graduate Theses and Dissertations

The religious Reformation in England heralded significant changes in Christian theology, clerical and lay practices, and textual interpretation. These sweeping changes encompassed nearly all avenues of intellectual thought, and debates ranged from whether or not religious texts should be written in the traditional latin or the vernacular, thereby determining whether interpretive authority remained within the clergy or became available to laypersons, to arguments over very specific aspects of theological doctrine, such as the substantive nature of the Eucharist. These debates were not confined among Church officials; politicians, monarchs, commoners, and literary authors engaged in these discussions and had been doing …

The Experiences Of A Black Teacher Educator Surrounded By Whiteness In Teacher Education: A Critical Autoethnography, Lamicah Lindsey

USF Tampa Graduate Theses and Dissertations

The present study examines cultural representations in two widely used AFL textbook series, namely Al-Kitaab and Arabiyyat al-Naas. Fundamentally, three main issues motivate this study: (1) the cultural politics of language textbooks underlying the construction and dissemination of cultural knowledge and its prioritization of the latter on grounds of subjectivity, ideology, and power, (2) the politicization of Arabic as a foreign language (AFL) in light of the post 9/11 language advocacy, and (3) the prevailing standard language ideology of al-Arabiya al-fuṣħaa (العربية الفصحى) and the pedagogical challenges posed by Arabic diglossia. The data comprise five textbooks from the aforementioned series, …
