Dating Application Facilitated Victimization: An Examination Of Lifestyle-Routine Activities, Self-Control, And Self-Efficacy, Vanessa Centelles

USF Tampa Graduate Theses and Dissertations

The current study examines how college students participate in the use of location-based real-time dating (LBRTD) applications and the correlates of in-person and cyber victimization. Using an exploratory lens, the present study draws on the classical criminological theories of lifestyle-routine activities (L-RAT), self-efficacy, and low self-control which have been applied to various forms of abuse. Although the use of LBRTD applications has become relatively common place, with approximately 15% of Americans reporting having used a mobile dating application or online dating site, little is known concerning the role these applications play, particularly among college students (Boillot-Fansher, 2017; Smith, 2016). Using …

The Role Of Social Media Journalists In Tv News:Their Effects On The Profession And Identity Of Tv Journalism, The Quality Of News, And Theaudience Engagement, Yousuf Humiad Al Yousufi

USF Tampa Graduate Theses and Dissertations

Spurred by the rapid influence of social media in the news industry, an increased number of TV news stations have started assigning dedicated social media journalists (SMJ) in newsrooms to monitor, gather, verify, share news, and engage with audiences on the streams of social media. Consequently, drawing on the diffusion of innovation theory, the present study probes into TV journalists’ perceptions of the implications of the role of this new type of TV professionals in the identity and profession of journalism, the quality of news pertaining to the verification of misinformation, and the news audiences’ attractions and viewership by capitalizing …

Plasticity In Animated Children’S Cartoons: The Neoliberal Transforming Bodies And Static Worlds Of Ok Ko And Gumball, Rachel E. Cox

USF Tampa Graduate Theses and Dissertations

Through the study of OK KO! Let’s Be Heroes! and The Amazing World of Gumball, I argue that children’s cartoons represent and recreate anxieties toward money’s plasticity in the plasticity of the cartoon bodies and worlds. I closely examine the ambivalence towards abstraction’s plasticity in contemporary children’s cartoons to trace the neoliberal ambivalence towards money’s plasticity. While much scholarship has grappled with what can be understood as animatic plasticity, very little of it takes on the questions raised about neoliberal culture by televised children’s cartoons. Cartoons are important to study in this respect because their form allows for unbridled plasticity. …

"Roll" Models: Fat Sexuality And Its Representations In Pornographic Imagery, Leah Marie Turner

USF Tampa Graduate Theses and Dissertations

The purpose of this thesis is to use specific fat pornographic imagery as a means to help us understand fat tropes and fetishization. The goal is to use our understandings of masculinity and race within fatness to create a possible launching point for further study within the field of fat sexuality studies. My rationale for writing such a paper is because fat sexuality studies is a field which has very little content, but potential for incredible scholarship which can impact not only our understandings of fat bodies, but of all bodies. The method for this thesis involves looking at specific …

Iron-Virus Interactions: Development And Testing Of The Ferrojan Horse Hypothesis, Chelsea Bonnain

USF Tampa Graduate Theses and Dissertations

Iron is an essential micronutrient for phytoplankton metabolism that limits growth in many regions of the surface ocean. More than 99.9% of oceanic dissolved iron is organically complexed to an iron-binding ligand, many of which have yet to be characterized. This thesis puts forth the Ferrojan Horse Hypothesis, which predicts a role for marine phages in oceanic iron cycling. Based on evidence from non-marine model systems, the Ferrojan Horse Hypothesis suggests that some marine phages (short for bacteriophages, or viruses that infect bacteria) can use iron as a “Trojan Horse” to gain access to host siderophore-bound iron receptors for infection. …

International Teaching Assistants’ Perceptions Of English And Spanish Language Use At The University Of Puerto Rico-Mayagüez, Edward G. Contreras Santiago

USF Tampa Graduate Theses and Dissertations

Globalization and sociopolitical factors impact migration patterns all over the world. In Puerto Rico, these factors created superdiverse environments where languages users have pushed the boundaries of language in order to make sense of their worlds. Even though this language dynamic is natural for locals, it is those who visit from different countries, specifically international graduate students, that have a difficult time adjusting to Puerto Rico’s rich use of English and Spanish. Understanding how international graduate students perceive the language used at the University of Puerto Rico, Mayagüez (UPRM) upon arrival is essential to provide a better experience for future …

Cyclosporine (CsA) is one of the main immune-suppressant agents which has been used widely in organ transplantation against graft rejection. However, the low oral bioavailability and the associated adverse effects such as nephrotoxicity are the main drawbacks of current usage of this drug. Thus, purpose of this research is to formulate PLGA nanoparticles of CsA to improve its effectiveness and to reduce the nephrotoxicity induced by the plain drug. CsA-loaded PLGA nanoparticles were prepared by the nanoprecipitation method. Particle size and zeta potential of the formulation was determined and percent drug entrapment were also determined. Quantitative estimation was carried out …

Promoting L2 Idiomatic Competence Among Chinese College Students Via Wechat, Zhengjie Li

USF Tampa Graduate Theses and Dissertations

Many second language (L2) scholars acknowledge that L2 idioms play a critical role in reading development as well as in communicative competence for L2 learners (Arnaud & Savignon, 1997; Barfield & Gyllstad, 2009; Conklin & Schmitt, 2008; Howarth, 1998; Liontas, 2017; Littlemore, Chen, Koester, & Barnden, 2011). Echoing the current trends of Computer Assisted Language Learning (CALL), much research has been done to underscore how L2 idiom learning can be infused with instructional technologies to promote L2 learners’ idiomatic competence (see Luk & Ng, 1998; Nakata, 2011; Yang & Xie, 2013). However, what remains underexplored is the ways that L2 …

The Humanitarian Gaze And The Spectatorial Nature Of Sympathy, Michelle Assaad

USF Tampa Graduate Theses and Dissertations

Ansel Adams, one of the world’s great photographers, once said, “There are always two people in every picture: the photographer and the viewer.” This thesis will explore the relationship of the photographer, the viewer, and the photographed subject in the context of humanitarian photography, which has historically internalized a specific balance of power between the worlds of the photographer, viewer, and subject. By examining this tangible expression of the internalized world, this thesis is also performing a critical examination of humanitarianism itself with the intent of improving humanitarian practices and interior worlds. In examining these topics, this thesis will answer …

Rethinking Map Literacy And An Analysis Of Quantitative Map Literacy, Ming Xie

USF Tampa Graduate Theses and Dissertations

Maps are increasingly being used in traditional and virtual media, and civic discourse on political, social, and environmental issues, among others, is more and more becoming influenced by them. The often-used expression of a “picture tells a 1000 words” has never been so apt in our progressively more visual world. Despite this increased role and importance of maps, map literacy, as a field of research, remains rather underdeveloped. This is especially so for thematic maps, the very type of map that is finding increasing currency in discourse. As part of this under-developed nature of map literacy, the quantitative skills used …

Morphology And Detection Of Corrosion On Stainless Steel Reinforcement In Concrete, Julio J. Saire Yanez

USF Tampa Graduate Theses and Dissertations

Stainless steel (SS) has emerged as an alternative corrosion-resistant reinforcement in concrete instead of the commonly used carbon steel (CS). The biggest advantage of SS is that it takes more time for corrosion to initiate than for CS. An additional benefit from the use of SS in concrete may be derived from the period after the corrosion started until the concrete structure reaches a limit state. This period is called corrosion propagation stage (CPS) and it has been hardly studied in SS reinforced structures. The duration of this period could be related, among other factors, to the morphology of corrosion …

Measuring Influence Across Social Media Platforms: Empirical Analysis Using Symbolic Transfer Entropy, Abhishek Bhattacharjee

USF Tampa Graduate Theses and Dissertations

Social media platforms are interconnected environments that influence each other. Information from one social media platform spreads to another. This thesis proposes a platform-independent framework to analyze information transfer across social media platforms. This thesis uses Symbolic Transfer Entropy and Statistical Significance Test to measure influence and optimize the time window of influence between different platforms. To validate the framework, the thesis analyses the temporal activity dynamics and the information transfer across three different platforms, Reddit, Twitter and GitHub.

Two data driven studies are described in this thesis. The first study finds the optimum time windows of influence between the …

Fear, Death, And Being-A-Problem: Understanding And Critiquing Racial Discourse With Heidegger’S Being And Time, Jesús H. Ramírez

USF Tampa Graduate Theses and Dissertations

I use Heidegger’s Being and Time to understand and critique racial discourse, but to also determine Heidegger’s reach into issues like racial identity. I start by examining how his introductory statements in Being and Time on the term “existentiell” suggest a path towards a conception of identity. I then go into how a racial identity could, through his terminology, be conceived as what I call a “fear existentiell.” I demonstrate how society assists the individual in maintaining a racialized existence that is embedded in fear. I move toward an examination of Heidegger’s three concepts of death to demonstrate how two …

Characterization Of The Autophagic-Iron Axis In The Pathophysiology Of Endometriosis And Epithelial Ovarian Cancers, Stephanie Rockfield

USF Tampa Graduate Theses and Dissertations

For women in the United States, ovarian cancer (OVCA) represents the deadliest gynecological cancer with over 14,000 deaths predicted to occur in 2019 [13]. Although innovative treatment strategies have improved the 5-year outcome for these patients, the overall survival has not changed in over 40 years [14]. This is largely due to the challenges in detecting this heterogenous disease at an early stage, as there are multiple potential precursors that may give rise to different histological subtypes [14]. This dissertation is thus focused on investigating pro-survival pathways involved in the pathogenesis of endometriosis (a proposed precursor) and epithelial ovarian cancers. …

Representations Of Indian Christians In Bollywood Movies, Ryan A. D'Souza

USF Tampa Graduate Theses and Dissertations

This dissertation uses discursive formation as the methodological approach to examine representations of Indian Christians in eleven Bollywood movies released during the 2004-2014 decade. The decade witnessed the exit and eventual re-entry of the Hindu Right, and the citizenry during that period experienced centrist, liberal, and secular governance. Since the present of Indian Christianity is inextricable from a colonial past, and Bollywood emerges in response to colonialism, a postcolonial intervention in methodology and theory is undertaken. A postcolonial perspective illuminates the discourses that enable the formation of the postcolonial nation, i.e., the ways a nation imagines its culture, people, traditions, …

Examining Efl Learners’ Reading Comprehension: The Impact Of Metacognitive Strategies Discussion And Collaborative Learning Within Multimedia E-Book Dialogic Environments, Abrar H. Alsofyani

USF Tampa Graduate Theses and Dissertations

For most English as a Foreign Language (EFL) learners, both reading and comprehension skills are challenging to acquire. EFL students find reading challenging due to their inability to comprehend and interpret text information, which may lead, at times, to demotivation and loss of interest. The current study intends to explore how Saudi EFL learners may better tackle reading comprehension challenges by examining the utilization of metacognitive reading strategies through discussion and extensive collaborative learning activities within a multimedia e-book dialogic environment. Accordingly, the study investigates the impact of teaching metacognitive strategy-based discussion and collaborative learning on students’ application of the …

Localization Of Five Target Proteins In Tachyzoites Of Toxoplasma Gondii, Abigail M. Kaiser

USF Tampa Graduate Theses and Dissertations

Five target genes were selected in Toxoplasma gondii tachyzoites for localization studies. These five genes, detected through proteomics studies, included TgME49_227450, TgME49_223080, TgME49_262390, TgME49_230940, and TgME49_269620. Localization of these five target proteins is a first step to confirm their interaction with TgCrk2 and understand their function and role in TgCrk2 regulation of the tachyzoite cell cycle. Gene models for the targets were analyzed using ToxoDB and ApE analysis tools. Endogenous tagging constructs were created for each target. Transgenic parasites were created. Finally, localization analysis of the target proteins in tachyzoites was completed using immunofluorescent microscopy following. One protein was found …

Mobilizing Images Of Black Pain And Death Through Digital Media: Visual Claims To Collective Identity After “I Can’T Breathe”, Aryn Kelly

USF Tampa Graduate Theses and Dissertations

In the wake of Eric Garner’s 2014 public execution at the hands of NYPD officers, online spaces such as Twitter saw an influx of remediated imagery referencing Ramsey Orta’s bystander cell phone video of Garner’s death. These images often explicitly reference the chokehold that killed Garner and/or they reappropriate Garner’s last words: “I can’t breathe.” To what formal dimensions in Orta’s video are these remediated images responding? What broader cultural work is the creation of these images doing?

In this project, I regard Orta’s video as the point of entry for considering the cultural work of remediating images from it, …

Baltimore Mobility: The Wire, Local Documentary, And The Politics Of Distance, Richard M. Farrell

USF Tampa Graduate Theses and Dissertations

Extending scholarship on Baltimore’s media landscape, I observe how two moving-image texts, HBO’s The Wire (David Simon, 2002-2008) and 12 O’clock Boys (Lotfy Nathan, 2013), figure space and, by extension, mobility in the city. Specifically, I articulate how both figures of mobility relate with each other and to the mobility inequality that has historically and disproportionately plagued communities along the city’s east-west axis. Overall, in both texts, I read a shared anxiety toward sources of distant mediation. Through its sober audio-visual style and serial organization, I find The Wire fatalistically figures Baltimore mobility as conditioned by omnidirectional flows of power. …

A Functional Approach To Bullying Prevention And Reduction: The Development And Evaluation Of The Functional Behavior Assessment For Bullying-Behavior In Schools (Fabb-S), Lindsey Slattery

USF Tampa Graduate Theses and Dissertations

Bullying is reported to be one of the most prevalent forms of violence in schools and has negative health, financial, and social outcomes. Researchers define bullying as (a) aggressive behavior that is (b) repeated over time and that involves (c) a real/ perceived imbalance of power. The literature on bullying is limited due to the absence of functional behavior assessment procedures and individualized interventions for bullying behaviors. Study 1 developed the Functional Assessment of Bullying Behaviors in Schools (FABB-S) tool. Following expert review 21 items were found to have content validity. Following revision, the items were reviewed by child work …

Investigating The Proteinaceous Regulome Of The Acinetobacter Baumannii, Leila G. Casella

USF Tampa Graduate Theses and Dissertations

Acinetobacter baumannii is an opportunistic pathogen that overtime has evolved into one of the most problematic pathogens due to its ability to overcome antibiotic pressures and harshly environments in the host and hospital environments. In this context, its genomic evolution due to its capacity to acquire genes that contribute to its pathogenic and antibiotic resistance nature has been the subject of research in the last decades providing with the identification of several proteins aiding in the process of pathogenicity. Although these findings have contributed to our understanding of A. baumannii pathogenic traits, the regulatory network that control their expression are …

Understanding The Adoption Process Of An Hpv Vaccine School-Entry Requirement In Puerto Rico, Coralia Vázquez-Otero

USF Tampa Graduate Theses and Dissertations

Human Papillomavirus (HPV) is the most common sexually transmitted infection (STI) in the US. Infection with low-risk HPV (i.e., 6 and 11) can cause genital warts, and persistent infection with high-risk HPV types (i.e., HPV 16 and 18) can progress to cancer. Currently, there is an HPV vaccine that is recommended for boys and girls, aged 11 to 12. Healthy People 2020 established a national objective of 80% completion of HPV vaccination among children aged 13 to 15 years old.
