Multivalency Of The Mdmx Acidic Domain Slims Use Different Binding Modes To Inhibit Mdmx And P53, Malissa Fenton

USF Tampa Graduate Theses and Dissertations

Regulation of protein binding through autoinhibition commonly occurs via interactions involving intrinsically disordered regions (IDRs). These intramolecular interactions can directly or allosterically inhibit intermolecular protein or DNA binding, regulate enzymatic activity, and control the assembly of large macromolecular complexes. Autoinhibitory interactions mediated by protein disorder are inherently transient, making their identification and characterization challenging. In this work, we explore the structural and functional diversity of disorder-mediated autoinhibition for a variety of biological mechanisms, with a focus on the role of multivalency and effective concentration. We also discuss the evolution of disordered motifs that participate in autoinhibition using examples where sequence …

Platonic Intelligence And The United States Constitution, Elizabeth M. Iglesias

USF Tampa Graduate Theses and Dissertations

This dissertation demonstrates the Platonic logic that informs the order of value and design elements of the U.S. Constitution as defended in the Federalist Papers. The dissertation has four movements that reveal the Platonic logic of the U.S. Constitution. The first takes up the repudiation of tyranny in defense of a way of being called ordered liberty in both Plato and the Federalist. The second takes up the commitment to the supremacy of intelligence over power, an order of value that is distinctly Platonic and permeates the design logic of the U.S. Constitution. Intelligence in this context is understood as …

As the field of machine …

Effectiveness Of Contact-Based Strategies On Improving Mental Illness Stigma And Help-Seeking Behaviors Within Families, B. Michelle Wilks

USF Tampa Graduate Theses and Dissertations

Adolescence is a developmental period that often involves extreme physical, psychological, and emotional changes and sometimes the experience of significant personal and social challenges. In addition to these challenges, youth are trying to find their place in the world and developing their identities, which depend heavily on their relationships with others. Adolescents who struggle with their mental health and also fail to develop meaningful connections with others, tend to have poor self-esteem, self-isolate, are ostracized by others, and have a poor social self-concept, all of which are associated with poor mental health and increased risk for suicidal ideation. The impact …

Sociocultural Factors, Definitions, And Experiences Of Intimate Partner Violence Among Latina And Hispanic Women, Vanessa Centelles

USF Tampa Graduate Theses and Dissertations

Intimate partner violence (IPV) is a pressing public health concern in the United States (US), particularly for women. Some studies have shown that Hispanic and Latina women are at an elevated risk of experiencing IPV due to a notable passiveness of violence among traditional Hispanic and Latina women. Thus, it is crucial for research to examine the effects of sociocultural variables—such as cultural orientation, gender norm beliefs, and ethnic identity—on IPV within this demographic, particularly for women in the US. Furthermore, while the experiences of IPV victimization among Hispanic and Latina women have begun to be recognized in the broader …

Stereotyped Non-Stereotypicality: Exploring Positive Effects Of Non-Stereotypical Gender Portrayals On Consumer Perceptions, Veronika Ponomarenko

USF Tampa Graduate Theses and Dissertations

This research attempts to identify contexts where non-stereotypical gender portrayals may have positive effects on consumer perceptions. It tests the perceived self-expressiveness of non-stereotypical gender portrayals as the mediating mechanism behind these effects as well as other alternative mechanisms in a comprehensive experiment. The analysis results show that an interpretation of gender through the theoretical lens of extravagance rather than self-expressiveness seems to be more appropriate. This study also introduces an overarching theoretical framework of metacognitive experiences that may explain the processes driving the effects of non-stereotypical gender portrayals on consumer perceptions. Finally, this research explores different types of gender …

Making The Invisible Visible: (Re)Envisioning The Black Body In Contemporary Adaptations Of Nineteenth-Century Fiction, Urshela Wiggins Mckinney

USF Tampa Graduate Theses and Dissertations

A trend in neo-Victorian adaptations -- both novels and films-- that reimage, and at times reinterpret, canonical Victorian texts is the inclusion of nonwhite, mainly Black, perspectives, which has gained considerable traction in recent years. A vital aspect of this trend is the purposeful attempt to re-establish iconic Victorian characters through Black characterizations. In doing so, filmmakers and authors are reinvigorating familiar texts to provide an inclusionary space for the Black experience previously ignored in the original texts. These adaptations, which revisit and often reinterpret Victorian fiction, have undergone notable transformations by incorporating Black characters to fill voids in traditional …

The Rust Belt Gothic: Charting The Affective Politics Of Deindustrialization And The Emergence Of A Great Lakes Horror Genre In Film, Micheal B. Raines

USF Tampa Graduate Theses and Dissertations

Within the past decade, a string of notable horror films set within the Steel Belt has emerged. These works collectively invoke the specter of the ‘Rust Belt’ in their narratives: the industrial Midwest’s derelict urban and suburban sprawls in the wake of the economic decline and white flight of the USA’s once-mighty manufacturing sector. Scholarship has commented upon the subtext of these works individually but fails to observe their collective nature as an emergent subgenre in horror fiction, centered upon directly confronting the Steel Belt’s twentieth-century history of stagnation. In this paper, I examine films which share clear aesthetic and …

Disability, Blackness, And Online Community: Black Twitter As Self-Narrative, Morgan S. Wilson

USF Tampa Graduate Theses and Dissertations

Black disabled people, especially those with invisible disabilities, are often not included or welcomed by all in the disabled community. In addition, Black disabled individuals also face discrimination and exclusion within the Black community due to ableism. This project will be an investigation of Black disabled community and health culture in online spaces, specifically using Twitter hashtags as a starting point. This research project is about helping to write the whole story, an opportunity that my Black ancestors did not have but still demand, for our generation and those who will come after us.

Zeros And Ones: Digital Video Aesthetics And Geopolitical Economy In Blackhat, Everett Barnett

USF Tampa Graduate Theses and Dissertations

Film and media theory has been fundamentally altered by the advent of digital technology, both in terms of film production and broader aesthetic overtures but also in terms of greater digital mediation. Blackhat (Michael Mann, 2015), although not a commercial or critical success, articulates many of the exact circumstances and broader consequences of digital technology in relation to its digital video aesthetics but also its narratives content involving global telecommunication and data systems. As a wholly digital film, Blackhat is uniquely situated to speak not only developments in digital filmmaking but also, by way of its plot line involving stateless …

Unveiling Estrangement: The Ambivalence Of Iranian Cultural Identity In Documentary Films, Vahid Valikhani

USF Tampa Graduate Theses and Dissertations

This paper examines estrangement within Iranian society as depicted in Iranian documentaries, which, I argue, regularly suppress the complexities of Iranian cultural identity. While Iranian narrative cinema has been studied in this context, documentaries have received less scholarly attention, despite their potential to illuminate the shortcomings of conceiving Iranian cultural identity. I examine three documentaries: Tehran Today (Ahmad Faroughi Ghajar, 1962), Newcomers (Kianoush Ayari, 1979) and Tehran Without Permission (Sepideh Farsi, 2009). Through this analysis, I uncover various forms of estrangement, including those induced by westernization, gender oppression, and the political control of what Hamid Naficy calls “mediawork.” Drawing on …

Integrating Identities By Segmenting Domains: Antecedents Of Work-Maternal Identity In The Postpartum Return To Work, Aashna M. Waiwood

USF Tampa Graduate Theses and Dissertations

As employed women have children and return to work, they encounter a cross-domain identity transition where their professional and maternal identities are consistently co-activated and must perceptually contend with one another. In this dissertation, I explored this potential for harmonious assimilation of work and parental identities within this postpartum transitory period via a novel construct termed “work-maternal identity (WMI).” Specifically, I examined how working remotely in integrated work and home environments is related to WMI, as mediated by job engagement and perceptions of work belongingness. I also incorporated factors critical to successful resocialization and related to boundary management as moderators …

Lawful Injustice: Novel Readings Of Racialized Temporality And Legal Instabilities, Danielle N. Mercier

USF Tampa Graduate Theses and Dissertations

This project, “Lawful Injustice: Novel Readings of Racialized Temporality and Legal Instabilities,” examines three specific BIPOC communities across literature—Native American, African American, and Asian American—to understand the influence of U.S. legal frameworks and temporalities upon both the collective and the individual. I assess how legal frameworks create and protect their own instabilities as well as understand how they are produced by the uneven temporal structures of the law. I examine how such legal and settler colonial temporalities are at odds with Native American, African American, and Asian American temporalities. These temporalities—a legal/juridical temporality which reinscribes settler colonial oppression and the …

Curricula As Ideology: A Study Of Cultural Representations In Arabic As A Foreign Language (Afl) Textbooks, Zakaria Fahmi

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, …

Effects Of Diminazene Aceturate On Drosophila Melanogaster: A Lipidomic Analysis, Gabriela Suarez

USF Tampa Graduate Theses and Dissertations

Pesticides are agents designed to eradicate living organisms to preserve agricultural needs.¹ Today the most commonly used pesticides are termed “modern pesticides”, they are characterized by lower lipophilicity and limited stability, making them less time persistent in the environment. Among these modern pesticides are organophosphorus, urea, phenoxy alkanoic, triazine, chloroacetanilide, and glyphosate-based pesticides.² The issue faced with most of these pesticides is that they affect more than just the targeted pest and pose a danger to not only humans, but also entire ecosystems.^1,3,4 While there are many different types of pesticides, insecticides show the most variance and …

A Longitudinal Investigation Of The Relationships Between Experiences With Sexual Harassment, Self-Objectification, And Self-Concept Clarity Among Women, Roxanne N. Felig

USF Tampa Graduate Theses and Dissertations

This longitudinal research investigates the nuanced relationship between sexual harassment and self-concept development among both men and women over a six-week period, presenting a unified model that integrates theories of self-objectification and self-concept clarity. Across three waves of data collection (N= 370, N=315, N=279, respectively), I find evidence that women experience higher rates of sexual harassment, greater self-objectification, and lower self-concept clarity than men. Across time, I find that experiencing sexual harassment predicts heightened self-objectification, which further predicts a disrupted sense of self among both men and women. Critically, this work investigates the reciprocal nature of self-objectification and self-concept clarity, …

Dissolved Nitrogen Removal In Biochar Amended, High Permeability Media For Urban Stormwater Treatment, Mark Vicciardo

USF Tampa Graduate Theses and Dissertations

Nutrient pollution in stormwater drives the eutrophication of inland and costal waterbodies which leads to sea grass retreat and the proliferation of harmful algal blooms (HAB). These anthropogenic effects destabilize ecosystems, and some HABs can pose direct human health risk. Bioretention, or the storage and controlled discharge of stormwater run-off in an ecologically engineered setting, is a potential solution to this problem. However, it relies heavily on the settling of particles as a nutrient removal mechanism, and thus struggles with pollutants, such as dissolved nitrogen, which is a particular problem in Florida where the geological prominence of phosphorus leaves nitrogen …

The Prevalence And Perceptions Of Self-Relevant Research (“Me-Search”) In Psychological Science, Andrew R. Devendorf

USF Tampa Graduate Theses and Dissertations

Self-relevant research (i.e., me-search; SRR) is research that is informed by lived experience or having close connections to a topic. The disclosure of SRR may impact how a researcher is viewed in professional contexts, like an application to graduate school, and thus can impact who is recruited and retained in psychology. Although SRR appears to be common in psychology, little systematic research exists on its prevalence by subfield of psychology or how SRR is perceived. This study examined SRR across psychology disciplines. An online survey was administered to faculty and graduate students (N = 1313) affiliated with accredited doctoral programs …

Tangled Threads: The Emerging Ideology Of Far-Right Islamic Conservatism In The Muslim Diaspora, Veli John Muhammed Aydoner

USF Tampa Graduate Theses and Dissertations

Contemporary political science literature has done well to cover the recent resurgence of the far-right within Western political discourse. However, one notable blind spot within this literature comes from an even more recent development: Far-Right Islamic Conservatism (FRIC). FRIC represents an ideology constructed through an attempted synthesis of far-right conservative political thought with a particular interpretation of the Western Muslim and Islamic identities. This paper seeks to help alleviate this gap in the literature by contextualizing the foundations of FRIC’s attempted theoretical synthesis and by exploring its engagements within Western political discourse. Following a formative assessment of FRIC’s ideological development, …
