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.

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’ …

Reimagining The Single-Author Seminar: Teaching Wheatley Peters, Milton, And The Master’S Discourse, Kate Ozment

ABO: Interactive Journal for Women in the Arts, 1640–1830

This article discusses a senior-level literature course that puts into dialogue Phillis Wheatley Peters and John Milton. Wheatley Peters’ poetry on tyranny and freedom during the American Revolution, especially “America,” is compared to Milton’s Tenure of Kings and Magistrates, Areopagitica, and Paradise Lost, which explore the same themes during the English Civil War. Students trace how Milton’s transformative but narrowed ideas of freedom for enfranchised subjects in England are powerfully reimagined by Wheatley Peters in double meanings of freedom for the colonies and enslaved subjects. Secondary sources allow students to engage in the canon-building of Milton as …

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 …

USF Tampa Graduate Theses and Dissertations

Latine students often face systemic barriers to accessing appropriate mental health support, highlighting the importance of culturally responsive school-based interventions to address mental health disparities (Gonzalez et al., 2022; Jackson, 2021). Although many interventions incorporate caregiver involvement, limited research has explored how Latine youth experience and make meaning of caregiver engagement in school-based mental health programs (Hansen et al., 2021; Wildmon et al., 2024). This mixed-methods study centers Latine student voices by examining how Latine students experienced and interpreted caregiver engagement in the Well-Being Promotion Program (WBPP), a school-based positive psychology intervention implemented during the 2023–2024 school year across six …

Performing Presidential Age: "It's About How Old Your Ideas Are", Valerie Barnes Lipscomb

English Sarasota Manatee Campus Faculty Publications

During a February surprise appearance on Late Night with Seth Meyers, President Joe Biden whipped out his trademark aviator sunglasses and traded quips with Meyers about a supposed conspiracy with Taylor Swift, much to the delight of the younger live audience. The next day, reviews were mixed about whether the president was trying too hard or did in fact manage to look hipper. To look younger. While US presidential nominees have been consciously performing their campaigns for decades, during this cycle, considering age as a performance has been especially prominent. Commentators and critics have specifically addressed the careful staging of …

A New Nature Is Coming. We Will Be Repossessed, And The Spectres Of The Post-Natural Will Take The World. Predictions Of A New Symbiotic Earth In "Fafner" (2018) By Daniel Perez Navarro, Miguel Angel Albújar-Escuredo

Alambique. Revista académica de ciencia ficción y fantasía / Jornal acadêmico de ficção científica e fantasía

This paper engages in the debates about decentralizing the role of men in the world we live in. Byproducts of this new mindset are concepts such as the “Posthuman” (Braidotti 2012); the status of “Holobiont” (Haraway 2016), and the experiencing of a new “Coexistence” with the non-human (Morton 2018). I suggest the novel Fafner (2018) as a perfect sample of this intellectual debate from an artistic and fictional view. Using concepts from diverse fields of thinking and applying them to literary analysis, this paper will review the in-depth transformation of nature portrayed by Fafner’s narration. Additionally, it will accomplish …

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 …

This study provides insight …

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). …

An individual’s actions in a particular environment and with specified resources can reveal their decision-making tendencies and patterns, and by analyzing the variations in cognitive traits among individuals, it may be possible to identify trends that can foretell their future behaviors. This can be a powerful tool in various fields including cognitive modeling, player analytics, computer security, and threat detection. Collectible card games are a fruitful test space for studying cognitive differences in decision-making, as they can have clearly defined and replicable environments and large player bases. As such, in this work, I explore the potential of using two virtual …

“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

Forgotten Learners: An Examination Of The Experiences Of English Language Learners In Advanced Placement And International Baccalaureate Social Studies Courses, Elizabeth Rasmussen

USF Tampa Graduate Theses and Dissertations

The number of English Language Learners (ELLs) in the United States is rapidly increasing, particularly in high schools. Although the number of ELLs is growing at a fast pace in the United States, the number of ELLs enrolled in advanced educational programming has not increased. After an in-depth review of the extant literature, it is evident that limited scholarly research on ELLs in advanced coursework exists. This is especially true in AP and IB social studies courses, where in many states where “Open Access” and “AP for All” have been adopted.
