Motivations For Planning: Uncovering The Inhibitors To The Adoption Of Comprehensive Financial Planning For Business Owners, Daniel R. Gilham

USF Tampa Graduate Theses and Dissertations

Though comprehensive financial planning is well-known terminology, it is not a well-known or adopted concept. Broadly, financial planning is associated with investment management, but this approach is changing. Most research on financial planning is confined to the benefits, or process, behind planning. For business owners, coordinated, comprehensive financial planning should include the founder’s largest, most concentrated financial asset, the business they are running. The underlying motivations and bias that inhibit business owners from engaging in a comprehensive financial planning relationship has not been heavily researched. In this dissertation, I studied business owner inhibitors to the adoption of comprehensive financial planning …

Brain Metastasis-Associated Fibroblasts Secrete Fucosylated Pvr/Cd155 That Induces Breast Cancer Invasion, Emma Adhikari

USF Tampa Graduate Theses and Dissertations

Breast cancer (BC) continues to be the most diagnosed cancer and the second leading cause of cancer deaths in women worldwide. High mortality, in most cancers, is due to metastasis; BC is the most common source of one of the deadliest forms of metastasis–brain metastasis (BM) in female. Patients with triple negative breast cancer (TNBC) exhibit the highest incidence of BM and poorest survival outcomes upon diagnosis with BM. The prognosis of breast cancer brain metastasis (BCBM) remains poor because the blood–brain barrier (BBB) prevents the uptake of drug substances, including chemotherapeutic agents, targeted agents, and toxins, from the brain. …

Context Matters: Profiles Of Emotion Regulation At Work And Home, Roxanne C. Lawrence

USF Tampa Graduate Theses and Dissertations

Previous research has often examined emotion regulation strategies in isolation, without considering how they may combine to form distinct profiles of emotion regulation. This study aimed to address this limitation by identifying profiles of emotion regulation strategies in the work and home contexts, and by examining their associations with individual differences and outcomes. Latent profile analyses (LPA) with expression of naturally felt emotions and the three emotion regulation strategies suppression, avoidance, and reappraisal as indicators revealed three profiles at work (i.e., low regulators, high regulators, and drain regulators) and three profiles at home (i.e., low regulators, gain regulators, and drain …

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, …

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 …
