The Effects Of An Interactive E-Book On Promoting Idiomatic Competence And Motivation Among L2 Learners Of Arabic Language In Saudi Arabia, Alfaifi Adel

USF Tampa Graduate Theses and Dissertations

Native Arabic speakers used idiomatic expressions such as idioms, formulas, and collocations, in their daily communications. In learning Arabic as a second language (L2), effective communication requires “the ability to understand and use idioms appropriately and accurately in a variety of sociocultural contexts, in a manner like that of native speakers, and with the least amount of mental effort” (Liontas, 2015, p. 441). Yet, promoting L2 idiomatic competence in the classroom and beyond remains a difficult task (Liontas, 2006; Tabatabaei, 2012). The utilization of e-books in the learning environment in L2 teaching in the English language has received much research …

The Politics Of Waves: A Transnational And Cultural Surfing History Of Popoyo, Nicaragua, Jason R. Old

USF Tampa Graduate Theses and Dissertations

During the 1970s and 1980s, as surfers were carving out new international surf spaces around the globe, Nicaragua was on a much different trajectory—one that engendered the Sandinista guerrilla insurgency that deposed a four-decade-long, US-backed dictatorship in 1979. In response, the United States waged a decade-long, low-intensity counterinsurgency against the Sandinista government. While other surfing destinations were growing in popularity, notably neighboring Costa Rica, Nicaragua was, by most accounts, considered off-limits due to the conflict. In 1990, a watershed moment fostered an environment conducive to international tourism and foreign investment. The election of Violeta Barrios Torres de Chamorro ushered in …

Field-Base Exploratory Study Of Microbial Activity In Eight Potable Water Storage Tanks In Barbados, Katelyn M. Long

USF Tampa Graduate Theses and Dissertations

There have been many initiatives to combat the global phenomenon of water scarcity. Potable water storage tanks have become widely known among water insecure countries and communities to provide adequate water quantity and quality for consumer use. Despite ubiquitous use in many low- and middle-income communities (LMIC), knowledge of microbial activity inside potable water storage tanks is limited. Barbados is a Small Island Developing State (SIDS), labeled as a high income country, and also water scarce. The Barbados Water Authority (BWA) has adapted potable water storage tanks for hundreds of residents as a solution to water quantity and water quality …

Diazirines And Oxaziridines As Nitrogen Transfer Reagents In Drug Discovery, Khalilia C. Tillett

USF Tampa Graduate Theses and Dissertations

Synthetic organic chemistry has long served as a driver of innovation in the drug discovery and development process. Given the prevalence of the nitrogen atom in small molecule drugs, improved methods for C–N bond installation are in high demand. Heteroatom transfer reagents such as oxaziridines and diazirines can be used to selectively deliver nitrogen atom(s) to organic compounds. Herein, I’ll describe my work utilizing Armstrong’s oxaziridine (TBDOT) in peptide backbone modification, and diazirines (TPD) in the development of a hydroamination reaction.

Peptide backbone N-amination has emerged as an attractive peptidomimetic strategy in the design of amyloid aggregation inhibitors. In addition …

Deconstructing And Decolonizing Identities Of “Gender” And “Sex” When Viewed As Anti-Black: Black Narratives Outside Of The Binary, Didier Salgado

USF Tampa Graduate Theses and Dissertations

How is “Reality” experienced in the Black body? Is “Reality” an objective article which is outside of the realm of personal experience? Assigned sex is often assumed an objective biological phenomenon that exists everywhere and in all communities. Gender is often thought about as a socially constructed form of identity which is expressed in various ways. In this thesis, I critically examine the terror of “reality” on the Black body, looking at the ways that Black people who’ve experienced discomfort with gender and sex categories experience the “world” around them. Diving deeply into their own experiences and the meanings they …

The 'Charm And Distinction' Of Proverbs: The Duality Of The Gem Analogy In Erasmus's Adagia, Blythe Broecker Creelan

USF Tampa Graduate Theses and Dissertations

Throughout the Adagia, Erasmus of Rotterdam frequently compares proverbs to precious gems and gemstone jewelry. My interdisciplinary study contributes to the broader discussion of Erasmus’s use of imagery by evaluating the specific qualities Erasmus associates with gemstones as analogous to the qualities he argues synonymously describe proverbs, specifically how both possess and imbue “charm and distinction.” The historical use of gemstones as essential for the display of social status and political power coupled with the contemporaneous belief in amuletic and astral magical properties of gemstones reveals the complex connections Erasmus forges between the qualities of gemstones and proverbs. Erasmus’s marked …

Social Media And Women Empowerment In Nigeria: A Study Of The #Breakthebias Campaign On Facebook, Deborah Osaro Omontese

USF Tampa Graduate Theses and Dissertations

This paper examines how the March 2022 #BreakTheBias campaign on Facebook was used as an empowerment platform in Nigeria, where women experience gender disparity. Research on the role of social media in women’s empowerment in Nigeria is an area that has not been fully studied. Previous studies have looked at women’s empowerment mainly through an educational or political lens, neglecting how social media have also been effective in empowering women. Other researchers have studied how women utilize social media platforms for leisure, entertainment, and media sharing. In the present study, non-probability sampling was used to identify 20 posts that convey …

Deep Reinforcement Learning Based Optimization Techniques For Energy And Socioeconomic Systems, Salman Sadiq Shuvo

USF Tampa Graduate Theses and Dissertations

Optimization, which refers to making the best or most out of a system, is critical for an organization's strategic planning. Optimization theories and techniques aim to find the optimal solution that maximizes/minimizes the values of an objective function within a set of constraints. Deep Reinforcement Learning (DRL) is a popular Machine Learning technique for optimization and resource allocation tasks. Unlike the supervised ML that trains on labeled data, DRL techniques require a simulated environment to capture the stochasticity of real-world complex systems. This uncertainty in future transitions makes the planning authorities doubt real-world implementation success. Furthermore, the DRL methods have …

Against God, Good Faith, And Reason: The 1381 Peasants’ Revolt In Cambridge, Reagan T. Vernon

USF Tampa Graduate Theses and Dissertations

This paper focuses on the Peasants’ Revolt of 1381 as it occurred in the university town of Cambridge. The historiographic understanding of the Cambridge wing of the Peasants’ Revolt has categorized it as foundationally motivated by town and gown resentment. Using legal records and chronicle accounts, this thesis demonstrates that the crowd did not exclusively target the university. As one of the town’s wealthier and increasingly authoritative institutions, the university and its constituents were targets in the uprising—but this was in addition to several attacks on local churches, monastic institutions, and manors. These attacks against higher authorities reflect a loss …

Of Mētis And Cuttlefish: Employing Collective Mētis As A Theoretical Framework For Marginalized Communities, Justiss Wilder Burry

USF Tampa Graduate Theses and Dissertations

This LGBTQ+ rhetoric of health and medicine (RHM) community-based research explores the ways community members and queer community participants communicate about potential intimate partner selection in Central Florida. The dissertation introduces the theoretical framework of “collective mētis” as a way to analyze and discuss community communication against Florida’s required HIV disclosure laws that attempt to medicalize this and control this community’s intimate partner selection. Research questions include: 1) How do people in counterpublic enclaves (Chávez, 2011) communicate their potential intimate partner desires to others in the community including the types of disclosures they express and negotiate, and how? 2) How …

This study compared the effects of video feedback (VF) as a stand-alone intervention and the effects of a video modeling plus video feedback (VMVF) as a package intervention for improving soccer players’ static ball control skills. This study used a multiple baseline across participants with an embedded alternating treatments design to compare VF and VMVF. This study involved two 10 year-old female soccer players and one 9 year old male soccer player. The same three target behaviors were assessed across participants. The first author implemented the VF and VMVF training procedures. The results showed that VF and VMVF produced similar …

The Invisible Victims Of Commercial Sexual Exploitation: Boys And Their Barriers To Access To Services, Amanda L. Connella

USF Tampa Graduate Theses and Dissertations

While there has been a large body of research conducted on girl (under the age of 18) victims of commercial sexual exploitation, boy (under the age of 18) victims do not seem to receive the same attention. From the few studies that have been conducted, boys and young male victims of commercial sexual exploitation have been shown to have gender specific barriers that prevent them from getting help, yet not many papers explore this unique problem. Using survey data from key providers that work in programs that serve commercially sexually exploited boys, the present study fills this hole in the …

This applied study uses a mixed methods approach to understand the following questions: what do the range of design courses look like in the field of TPC, how are these courses taught, and what would an effective design course look like? To answer these questions, this study uses a mix of three types of data: (1) institutional data on courses, (2) interviews with faculty and administrators who have taught (or are currently teaching) …

Academic Advisors' Perceptions Of Implicit Bias In Interactions With Students: An Exploratory Case Study, Bobby A. Brown

USF Tampa Graduate Theses and Dissertations

Academic advisors are crucial to the success of students who attend higher education institutions (e.g., Himes, 2014; Paul & Fitzpatrick, 2015; Smith, 2005). They guide students to complete their degrees in a timely progression and serve as a contact for students to help increase a sense of belonging on college campuses. Higher education literature presented evidence that suggested academic advisors demonstrate implicit bias while interacting with students they advise (e.g., Bahr, 2008; Grau & Zotos, 2016). Implicit bias may expose academic advisors to errors in judgment and decision making while assisting students. The purpose of this qualitative case study was …

Do Industries' Political Profiles Affect Their Portfolio Return Performance?, Shaddy S. Douidar

USF Tampa Graduate Theses and Dissertations

The political profiles of an industry influence its performance due to its impact on industry-level investor sentiment and idiosyncratic risk. I form eight comprehensive political profile portfolios after double sorting on industry-level: (1) political geography proxied by political alignment, (2) corporate political strategies (CPS), proxied by donations to political action committees & lobbying expenditures, (3) and government interference, proxied by dependence on procurement contracts & federal regulations, and exhibit that an industries’ political profiles impact its returns. Industries with high political alignment, concentrated corporate political strategies, and low government interference, deemed the high-performance portfolio, earn an annualized alpha of 10.3428%, …

Rehabilitation Technologies To Abate Infiltration In Sanitary Sewers, Steve Youssef

USF Tampa Graduate Theses and Dissertations

In urban coastal environments, sewer infrastructure is plagued by infiltration which seeps into aging and compromised pipes. Infiltration increases pumping costs, reduces treatment efficiency, and may trigger release of partially treated wastewater at water reclamation facilities. To restore pipes and abate infiltration, local utilities rely on structural and non-structural trenchless rehabilitation technologies. These methods are commonly used throughout the United States and the world due to their numerous benefits compared to traditional open-cut construction. However, limited data is available regarding their efficacy in reducing infiltration in sewer systems. In this study, we analysed infiltration in a small urban sewershed in …

Graph Analysis On Social Networks, Shen Lu

USF Tampa Graduate Theses and Dissertations

With the development of transportation network, social network, and communication network, there are many applications in streaming data. For example, traffic congestion happens between the origin and destination of daily trips. Traffic analysis can help plan the trips so that traffic congestion can be avoided. Social network and communication network represent the behaviors of the entire population. People build connections based on their hobbies, daily activities, photos, videos, simple messages, and even anonymous web surfing. All of these can be turned into commercial use, such as product marketing, business network building, and technology trending. Data science is about how to …

USF Tampa Graduate Theses and Dissertations

The purpose of this dissertation is to examine variations in the racial distribution of reported arrests across counties, and whether those outcomes are related to racial demographics variables and measure of the political structure in the State of Florida. The study seeks to bring awareness to the importance of representation of minorities by conducting a test of Blalock’s minority threat theory and extending the theory through the examination of political variables across Florida counties. Arrest and population data from 67 Florida counties along with the racial composition of the Florida State House of Representatives from 1998 to 2018 are utilized …

Nrf2 Sequestration By Ssh1 Tips The Balance From Neuroprotection To Neurodegeneration In Alzheimer’S Disease, Sara G. Cazzaro Buosi

USF Tampa Graduate Theses and Dissertations

Oxidative damage is one of the earliest events in Alzheimer’s disease (AD) pathogenesis and precedes the clinical stage of disease. The nuclear factor erythroid 2-related factor (Nrf2) is activated in response to oxidative stress, which protects the brain from oxidative damage and AD pathogenesis. Although Nrf2-mediated oxidative stress response declines with age and becomes dysfunctional in AD brains, the mechanistic basis for this dysfunction is unknown. Here, we demonstrate through in vitro and in vivo models, as well as in human AD brain tissue, that Slingshot homolog-1 (SSH1) acts as a counterweight to neuroprotective Nrf2 in response to oxidative stress …

I'Ll Make A Man Out Of You: Precarious Manhood Beliefs Among Heterosexual-Cisgender Men And Queer Men, Serena L. Wasilewski

USF Tampa Graduate Theses and Dissertations

Traditional masculine gender stereotypes often suggest that men should be strong, assertive, and athletic, and these stereotypes promote men’s dominance in society and gender inequality. Endorsement of masculine stereotypes may also contribute to heterosexual men being more prejudiced against queer men. Queer men experience unique difficulties in their quest to abide by social norms defining manhood. Research using the precarious manhood theory suggests that manhood is difficult to obtain and even more challenging to maintain. Given the emerging nature of precarious manhood studies, little is known about young men’s perceptions of the precarious nature of manhood and how this may …

Commitment To Change Dimensions: The Influence Of Innovative Work Behavior And Organizational Environments, Michael Holmes

USF Tampa Graduate Theses and Dissertations

The purpose of this dissertation was to examine the phenomenon of commitment to organizational change using both positive and negative organizational contexts and employee behaviors that may influence an employee’s commitment to change dimensions (affective, continuance, normative). A cross-sectional survey was used to collect data from 407 physician assistants across a national healthcare system and analyzed using descriptive statistics, exploratory and confirmatory factor analysis, and multiple regression to test the relationships among constructs. Results indicate that commitment to change dimensions are related to innovative work behavior, climate for innovation, and organizational constraints. Affective commitment was positively related to innovative work …

The Influence Of Covid-19 On Tobacco Racial Health Disparities: Testing The Differential Effects Of Covid-19 On Smoking Motivation Variables Across Black And White Smokers, Patricia F. Calixte-Civil

USF Tampa Graduate Theses and Dissertations

The COVID-19 pandemic has illuminated persistent racial differences in access and quality of healthcare resources that result in disproportionately poor health outcomes for Black and African Americans, relative to Whites. Given COVID-19’s influence on racial health disparities broadly, examination is warranted on whether the pandemic has more specificallyinfluenced smoking motivation and, subsequently, tobacco-related health disparities. The goal of this study was to test whether COVID-19 related video content differentially primed smoking motivation (cravings, cessation self-efficacy, and motivation to quit) among Black and White smokers. I used an online research platform to host an experiment with a 2x3 between-subjects factorial design …

Utilizing Neoantigen-Specific Cd4* T Cells And Immune Checkpoint Modulation To Advance Adoptive Cell Therapy With Tumor-Infiltrating Lymphocytes For Metastatic Melanoma Patients, Maclean Scott Hall

USF Tampa Graduate Theses and Dissertations

Adoptive cell therapy (ACT) with tumor-infiltrating lymphocytes (TIL) is a promising immunotherapeutic approach for patients with advanced solid tumors. Metastatic melanoma is a tumor type amenable to immunotherapy in part due to the presence of antigen-specific TIL. These T cells can be activated and expanded for ACT, which has resulted in relatively high rates of clinical responses. While numerous advances have been made, the inclusion of neoantigen-specific CD4+ T cells within TIL infusion products remains underexplored and therefore offers a significant opportunity for progress. Similarly, immune checkpoint inhibitors, specifically PD-1 blocking antibodies, augment antitumor immunity and may improve the outcomes …

Testimonios Of Civic Pedagogy: Developing Critical Literacy Skills Using Civics And Holocaust Studies, Tameka Parenti

USF Tampa Graduate Theses and Dissertations

Civics using Holocaust Studies offer a variety of pedagogical advantages. Regardless of the topic, Holocaust events can be used to build critical analytical skills and cultivate essential literacy skills about the social world. Further, the Holocaust can be used to introduce and grapple with the complex/abstract ideas of the civics content. Given the relationship that social studies has to critical literacy development, civics used in conjunction with Holocaust resources present teacher(s) (educators) with the opportunity to explore (theoretical) concepts foregrounding manifold relationships making up the social world.

This research aimed to examine how secondary students connect to the social world …

Interlocking Directorates: How Interpersonal Relationships Build Corporate Boards, Matthew A. Forrester

USF Tampa Graduate Theses and Dissertations

In an inductive network analysis research design, this dissertation seeks to understand the influence of the interlocking directorate networks on the selection of directors. Its intent is to understand both what the individual and organizational factors are and how those factors influence selection. A practice-inspired method was developed heavily influenced by my two decades within the United States Intelligence Community to create a common network structure to define an individual director’s relationship to a board in a given year. Then using manual approaches, I developed the networks of directors that form interlocking directorates from that network structure. I analyzed these …

Intermediate Algebra Students’ Perspectives Towards Learning Mathematics, And Technology, Caree J. S. Pinder

USF Tampa Graduate Theses and Dissertations

Research states that many remedial mathematics learners possess low mathematics academic self-concept, negative attitudes, and high anxiety levels. These aspects can manifest in a lack of confidence, apprehension, reduced engagement, or academic failure (2007; Klinger, 2008; Larkin & Jorgensen, 2016; Parnis & Petocz, 2016;). However, if these learners successfully pass remedial mathematics courses like Intermediate Algebra, they are more likely to persist in mathematics and the university (Benken et al., 2015). Due to students' success in remedial mathematics, persistence in mathematics raises many questions. In many cases, these students have had unpleasant experiences, attitudes, or beliefs about mathematics but were …
