Deep Learning-Based Automatic Stereology For High- And Low-Magnification Images, Hunter Morera

USF Tampa Graduate Theses and Dissertations

Quantification of the true number of stained cells in specific brain regions is an important metric in many fields of biomedical research involving cell degeneration, cytotoxicology, cellular inflammation, and drug development for a wide range of neurological disorders and mental illnesses. Unbiased stereology is the current state-of-the-art method for collecting the cell count data from tissue sections. These studies require trained experts to manually focus through a z-stack of microscopy images and count (click) on a hundred or more cells per case, making this approach time consuming (~1 hour per case) and prone to human error (i.e., inter-rater variability). Thus, …

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, …

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 …

A Gis Workflow For Analyzing Spatiotemporal Variance In Food Pantry Access: A Case Study For Hillsborough County, Florida, Molly J. Darby

USF Tampa Graduate Theses and Dissertations

Researchers often use geographic information systems (GIS) to measure accessibility to food pantries, but the impact operating hours have on accessibility remains understudied. Unlike grocery stores or healthcare facilities, food pantries have irregular distribution schedules, therefore, measuring geographic accessibility alone potentially creates an inaccurate or inflated representation of access. This study proposes a GIS workflow for analyzing food pantry accessibility over space and time by considering hours of operation and location, allowing researchers to examine when and where access to food assistance is most limited over the span of a typical week. The method was applied to Hillsborough County, Florida …

Gender Differences In Episodic Memory In Later Life: The Mediating Role Of Education, Sara Robinson

USF Tampa Graduate Theses and Dissertations

In the United States (U.S.), 14 million individuals aged 65+ are expected to be diagnosed with dementia by 2060, and women are nearly twice as likely to be diagnosed. Low education is a well-established risk factor for dementia and is hypothesized to partly explain the gender differences in late-life cognition. However, few studies have investigated education as a mediator of these gender differences. This study aims to investigate education as a mediator of gender differences in episodic memory using longitudinal data from the U.S. Health and Retirement Study (HRS). I used a sample of 35,721 respondents (20,190 women and 15,531 …

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 …

The Social Anxiety Stigma Scale (Sass): Development, Factor Structure, And Validation, Ruba Rum

USF Tampa Graduate Theses and Dissertations

The primary reason people with social anxiety disorder (SAD) do not seek treatment is due to stigma concerns. Yet, our understanding of SAD stigma hinges heavily on measures that assess general mental illness stigma, which may not capture the distinct aspects of SAD. The goal of this research program was to develop and validate a measure of social anxiety stigma that assesses personal stigma towards people with SAD: the Social Anxiety Stigma Scale (SASS).
