Reading Rent: Interracial Relationships And Racial Hierarchies, Susanna A. Perez-Field Oct 2023

Reading Rent: Interracial Relationships And Racial Hierarchies, Susanna A. Perez-Field

USF Tampa Graduate Theses and Dissertations

In examining the musical Rent by Jonathan Larson (1995) and its film adaptation by Chris Columbus (2005), most scholarly work and analyses have focused on the work’s identity as a queer text. I assert that elements of this musical have been overlooked for its depth of racial and class hierarchies. Utilizing sociological theory and interracial relationships, I will examine characters and musical numbers to explore diversity and class positioning.

I will explore Rent for themes of racial, gender, and sexual identities and how they are presented through the friendships and romantic relationships of the eight principal characters (alphabetically): Angel, Benny, …

Water Chemistry Variability In Peacock Springs Cave System And Spring Basin: Impacts On Continuous Monitoring Of Karst Aquifers, Mahnoor Kamal Oct 2023

Water Chemistry Variability In Peacock Springs Cave System And Spring Basin: Impacts On Continuous Monitoring Of Karst Aquifers, Mahnoor Kamal

USF Tampa Graduate Theses and Dissertations

The Upper Floridan Aquifer (UFA) is a highly transmissive and heterogeneous karst aquifer that makes it acutely susceptible to pollution. Rapid and extensive water quality changes in nutrients at springs draining the UFA have prompted intensive monitoring at several priority springs, including continuous and discrete water quality sampling. Springs, however, are a discrete discharge point of an often-expansive phreatic cave network that can intersect different land uses and thus drain distinct geographic areas of a springshed. The extensive network contains convergent passages from deep and shallow aquifer regions and may contribute to varying water chemistry across passages resulting in water …


Neuroendocrine Regulation Of Chemokine Receptor-Mediated Leukocyte Migration Via Heteromeric G Protein-Coupled Receptor Complexes, Garrett Enten Oct 2023

Neuroendocrine Regulation Of Chemokine Receptor-Mediated Leukocyte Migration Via Heteromeric G Protein-Coupled Receptor Complexes, Garrett Enten

USF Tampa Graduate Theses and Dissertations

Neuroendocrine regulation of the innate immune system is a well-documentedphenomenon. The underlying mechanisms, however, are not well understood. Here we show that at least 20 members of the human chemokine receptor (CR) family heteromerize with one or more members of the α1-adrenergic receptor (AR) family and that all CRs, apart from CXCR1, heteromerize with arginine vasopressin receptor 1A (AVPR1A) in recombinant systems. These heteromeric complexes are detectable in human monocytes and the monocytic leukemia cell line THP-1. Though currently technical limitations prevent the direct visualization of endogenously expressed higher-order hetero-oligomeric receptor complexes, we provide evidence through functional analysis and proximity-based …

Wastewater Treatment Using Encapsulated Chabazite In Polyvinyl Alcohol-Sodium Alginate Hydrogel Biofilm Carriers, Susieanna Nevada Persaud

USF Tampa Graduate Theses and Dissertations

Nitrogen discharge from wastewater is a global issue and with increased urbanization as well as industrialization, it has become even more essential to develop more efficient wastewater treatment systems. The dominant form of nitrogen in wastewater is ammonium. Biological oxidation of ammonium to nitrite and nitrate is the first step in biological nitrogen removal processes. If left untreated, nitrogen can cause toxicity to aquatic life, unsafe changes in water quality, and eutrophication.

Biofilm carriers can help to improve the efficiency of traditional activated sludge wastewater treatment systems by reducing operating costs and reducing hydraulic retention time. Biofilm carriers also promote …

Using NVivo software, the articles were analyzed to identify linguistic words and visuals that fell into coding categories based on Behrendt's (2008) contextual analysis for evaluating text. Each article was then coded again to identify common themes. During this process, new …


Regulated Intramembrane Proteolysis By M82 Peptidases: The Role Of Prss In The Staphylococcus Aureus Stress Response, Baylie M. Schott Oct 2023

Regulated Intramembrane Proteolysis By M82 Peptidases: The Role Of Prss In The Staphylococcus Aureus Stress Response, Baylie M. Schott

USF Tampa Graduate Theses and Dissertations

Staphylococcus aureus is a major threat to human health, which is only exacerbated by its resistance to methicillin and other frontline antibiotics. Consequently, annual hospitalizations resulting from methicillin-resistant Staphylococcus aureus (MRSA) have been recorded in the hundreds of thousands for decades. However, the global impact of this opportunistic pathogen cannot solely be attributed to its antibiotic resistance, as S. aureus is also an expert at adapting to host conditions and responding to external stress. Here we attempt to gain a better understanding of a S. aureus factor that aids in circumventing such external insult - PrsS - a membrane protease …

Evaluating Video Feedback To Improve Esports Performance In Street Fighter V, Romel C. White

USF Tampa Graduate Theses and Dissertations

eSports is a newly rising field with rapidly increasing cultural validity. Despite the wide array of similarities between eSports and traditional sports, behavioral skill acquisition interventions have yet to be applied to video game skills. Feedback-based behavioral interventions in particular have been commonly used and implemented for effective skill acquisition for traditional sports. Although video feedback has been established as effective in conjunction with video modeling for traditional sports, further research is needed to validate its efficacy as a standalone intervention. In this study, the effects of video feedback were analyzed with three participants in a nonconcurrent multiple baseline across …

An Examination Of Reward-Based Crowdfunding Performance And Success, Matthew Alan Grace Oct 2023

An Examination Of Reward-Based Crowdfunding Performance And Success, Matthew Alan Grace

USF Tampa Graduate Theses and Dissertations

Reward-based crowdfunding (RBCF), where fundraisers raise funds from a crowd of investors in return for a reward, has carved a niche as a proven option for not just entrepreneurs seeking early-stage funding, but also for established firms looking to presell or market a new product or service. Establishing crowdfunding performance and success factors is important for researchers and practitioners alike. Fortunately, a large portion of the RBCF academic literature is immediately applicable to entrepreneurs, with very little additional interpretation required. However, important questions about RBCF remain. The first paper in this three-part dissertation, a systematic literature review, examines some of …

The Effect Of Psychopathy Trait Descriptions On Mock Juror Decision-Making, Bailey A. Hall Oct 2023

The Effect Of Psychopathy Trait Descriptions On Mock Juror Decision-Making, Bailey A. Hall

USF Tampa Graduate Theses and Dissertations

Layperson misconceptions and stigma surrounding mental illness can have devastating consequences in criminal trials, especially capital (death penalty) cases. Psychopathy is a particularly stigmatizing disorder often used as an aggravating factor in capital cases. The present experimental study examined how case vignettes that included descriptions of psychopathic traits (i.e., criterion effects) differentially influenced juror decision-making. Specifically, undergraduate participants read case facts about a convicted defendant and were randomly assigned to read one of five expert witness testimony conditions describing the defendant using: interpersonal-affective psychopathy traits (e.g., superficially charming, manipulative), antisocial-lifestyle traits (e.g., reckless, aggressive), combined interpersonal-affective and antisocial-lifestyle traits, or …

GNSI Publications

TikTok is a social media application that has amassed over 100 million users in the United States. Yet the Biden White House, like the Trump Administration before it, seeks to ban TikTok, or at least force it’s divestment from the parent company, Bytedance. For many the question is how can an app for sharing silly dance videos among teenagers be a national security threat? Unfortunately, the problem is considerably more complex than this simple question. TikTok’s unprecedented success comes from its powerful artificial intelligence-based algorithm.

That activity produces a comprehensive psychological profile of each user and tailors the queue of …

Virtual Urban Siege: Modern Urban Siege And Swarming In Culiacán 2019 & 2023, Daniel Weisz Argomedo, Nathan P. Jones, Ph.D., John P. Sullivan, Ph.D.

Journal of Strategic Security

Modern urban siege is a metaphor for evolved urban campaigns. The template for such attacks draws from the tactics seen in the 26/11 Mumbai attack in 2008, and continued with the 2013 Westgate Mall attack in Kenya, the January 2015 Charlie Hebdo and Hyper Cacher attacks in Paris and the November 2015 attacks against the Stade de France and Bataclan. These virtual sieges employ swarming tactics, techniques, and procedures (TTPs) to provide a template for urban strife and insecurity. This article provides an overview of terrorist swarming tactics, expanding the aperture to review the use of similar TTPs by criminal …
