The Influence Of Maternal Body-Shaming Comments And Bodily Shame On Portion Size, Savannah R. Flak

USF Tampa Graduate Theses and Dissertations

Young adult women are more likely to be dissatisfied with their bodies (Wansink et al., 2017) and engage in disordered eating patterns when they have a history of receiving parental comments about their bodies during childhood (Fortesa & Ajete, 2014). Furthermore, high bodily shame mediates the relationship between receiving critical messages about eating from parents during childhood and disordered eating behaviors for young adult women (Oliveira et al., 2019). Altogether, this suggests that bodily shame is a distinct pathway linking parental influence during adolescence to eating disturbances. However, little research has examined the unique roles that bodily shame, internalized weight …

Bait-And-Kill: Targeting A Novel Heme Biochemical Pathway In Hundreds Of Cancers, Christopher G. Marinescu

USF Tampa Graduate Theses and Dissertations

Cancer cells are characterized by their ability to grow and proliferate in rates that far exceed normal cells by modifying their iron/heme metabolisms to levels higher than normal. This imbalance of heme biosynthesis can lead to cancer cells having a flux of heme intermediates to the point where they enter a state called heme-overdrive. Heme-overdrive is a process unique to a variety of cancers but absent in normal tissues. With this enhanced production, heme can act as an epigenic regulator for signaling proliferation (18). Through the novel strategy called ‘bait-and-kill,’ cancer cells will be coerced into a state of heme …

“Just Joking”: Women’S Cardiovascular Responses To Sexist Humor, Samantha Shepard

USF Tampa Graduate Theses and Dissertations

The ambiguity inherent to humorous communication may make women minimize experiences of sexist jokes, which may have downstream emotional and motivational consequences. The present thesis study tested whether the manner in which sexism is communicated, as a statement or joke, would reflect the motivational intensity model in cardiovascular responses during a performance-based task. Additionally, the present studies tested whether blatant and humorous sexism differentially affects emotional responses, evaluations of a male speaker, reporting of sexist misconduct, and ingroup identification. Using an online chat paradigm, participants were randomly assigned to receive one of three messages: a sexist joke, blatantly sexist statement, …

Defining Codes Based On The Consolidated Framework For Implementation Research In The Context Of The Implementing Universal Lynch Syndrome Screening, Jasmine A. Burton-Akright

USF Tampa Graduate Theses and Dissertations

Lynch syndrome (LS) is the most common hereditary cause of both colorectal cancer (CRC) and endometrial cancer (EC). Universal tumor screening (UTS) of newly diagnosed EC and CRC patients has been shown to be both an effective and economical approach to identify patients with LS and subsequently reduce future cancer s for patients and their family members. Despite its efficacy, LS UTS has not been consistently adopted across hospital systems and existing programs vary widely in their structure and execution. The Implementing Universal Lynch Syndrome Screening (IMPULSS) study aims to determine the critical factors necessary for successful implementation of LS …

Promoting Hpv Vaccination With Vaccine-Hesitant Parents Using Social Media: A Formative Research Mixed-Method Study, Silvia Sommariva

USF Tampa Graduate Theses and Dissertations

Vaccine hesitancy, the refusal or delay in complying with set immunization schedules, has been proclaimed one of the “ten threats to global health” by the World Health Organization in 2019. Since then, the COVID-19 pandemic has reinforced the importance of vaccine promotion and management of vaccine hesitancy. While anti-vaccine arguments have not surprisingly evolved much over the past decades, the speed at which those ideas spread has. Web-based technologies, such as social network sites (SNSs), provide a fertile ground for vaccine-related misinformation to spread. Therefore, SNSs are a primary channel to scale efforts to address vaccine hesitancy, using customized approaches. …

Drug Candidates Targeting Hsp90/Cdc37 For The Treatment Of Neurodegenerative Disease, Ryan Martin

USF Tampa Graduate Theses and Dissertations

Neurodegenerative disease refers to the death of specific populations of neurons that canresult in dementia, loss of voluntary muscle motility, and other abnormalities. Two major neurodegenerative diseases are Alzheimer’s disease (AD) and Parkinson’s disease (PD), which are linked to abnormalities in Tau and a-synuclein proteins, respectively. Currently, there is no cure for these diseases. Our group and others have shown that chaperone proteins play a critical role in the processing of Tau and a-synuclein. The inhibition of the Hsp90/Cdc37 chaperone complex is shown to affect the levels of these two proteins. Hence, we hypothesized that a drug molecule, conglobatin (Cb), …

Acclimatization Protocols And Their Outcomes, Ayub M. Odera

USF Tampa Graduate Theses and Dissertations

Heat acclimatization provides the opportunity to better tolerate heat stress. Different methods are used to acclimatize participants as part of heat stress studies in the laboratory. The usual acclimatization protocols are greater than the occupational exposure limit represented by the ACGIH TLV® and NIOSH REL. The purpose of this paper was to examine the acclimatization state prior to and at the end of a one-week acclimatization program using two acclimatization protocols.

Prior heat stress studies at the University of South Florida (USF) used two heat stress conditions for participants’ acclimatization. Participants (n = 43) were evaluated using four different studies …

This Is It: Latina/X Representation On One Day At A Time, Camille Ruiz Mangual

USF Tampa Graduate Theses and Dissertations

This thesis examines the tensions between contemporary Latina/x representations and problematic tropes in the sitcom, One Day at a Time (2017-2020) [ODAAT]. ODAAT centers of Elena, Penelope, and Lydia, three generations of a Latina/x family. Many entertainment reviewers and fans praised the series for its progressive and nuanced portrayals of Latina/x characters. However, I argue that while ODAAT depicts Latina/x characters that transcend some United States mainstream media tropes about Latinas/xs, the series also relies on conventional markers of Latina/x identity as tools with which to communicate progressive messages around identity. I expand upon scholarship in Latina/o media …

Young Adolescents’ Opportunity To Develop Concept Images Of Polygons In Middle School Mathematics Textbooks, Megan N. Cannon

USF Tampa Graduate Theses and Dissertations

Young adolescents build notions of figures through experiences. When young adolescentsbegin middle school mathematics, they already have prior assumptions and conceptualizations about shapes (Herbst, Fujita, Halverscheid, & Weiss, 2017). Over years of experiences, interactions, and exposures with a particular concept, these students develop concept images consisting of all the visual information, pictures, mental images, or properties associated with the particular mathematical concept (Vinner, 1983). Seminal works in the field of mathematics education research found that without an opportunity to engage with varied representations, young adolescent students may not develop robust concept images (Aspinwall, Shaw & Presmeg, 1997; Hasegawa, 1997; Mesa, …

Does Time-Weighted Averaging For Wbgt And Metabolic Rate Work For Work-Recovery Cycles?, John W. Flach

USF Tampa Graduate Theses and Dissertations

Heat stress affects thousands of works annually by causing heat-related illnesses. Wet bulb globe temperature (WBGT) is a widely accepted metric to assess the environmental contributions to heat stress. WBGT-based occupational exposure limits (OELs) include the ACGIH TLVs and the NIOSH RELs. The OEL threshold is adjusted downward with increasing metabolic rate. Further, there is an OEL for acclimatized and non-acclimatized workers. An often-recommended intervention found within a heat stress management program is work-recovery cycles to manage exposure. To prescribe work-recovery cycles, the common practice is to use time-weighted averaging (TWA) for the WBGT and the metabolic rate. The purpose …

Assessing Prompting And Prompt-Fading Strategies In Individuals With Autism Spectrum Disorder, Ashley L. Frankenfield

USF Tampa Graduate Theses and Dissertations

Autism spectrum disorder (ASD) is characterized by restricted interests, repetitive behaviors, and deficits in social and communication skills. In order to help a person with ASD improve their communication skills, behavior analysts should place emphasis on teaching intraverbal skills. Each person has a unique learner history, meaning that different prompts and prompt-fading techniques will result in the most accurate and efficient mastery of intraverbal skills for different people. Assessments were used to identify each participant’s most efficient combination of prompt and prompt-fading procedures in order to maximize one’s potential for learning new skills. Participants’ most efficient prompt/prompt-fading combinations resulted in …
