Addressing Intersectional Stigma: Lgbtq+ Individuals Living With A Mental Illness, Jennifer T. Tran

USF Tampa Graduate Theses and Dissertations

The stigma process (i.e., stereotyping, prejudice, and discrimination) has profound and lasting effects on individuals within marginalized identities. Research has indicated that lesbian, gay, bisexual, trans*, queer, or questioning (LGBTQ+) individuals’ experiences of stigma have contributed to the development of mental illness. Therefore, LGBTQ+ individuals living with mental illness experience a unique and challenging type of stigma, intersectional stigma, due to identification within multiple marginalized communities. Populations most vulnerable to stigma include individuals who identify with more than one stigmatized identity, such as LGBTQ+ individuals living with mental illness. Therefore, there is a need to explore strategies to address intersectional …

“That’S What We Call ‘Aesthetics’”: The Social Construction Of Tap Water Mistrust In An Underbounded Community, Abby Vidmar

USF Tampa Graduate Theses and Dissertations

Recent research on water insecurity in the United States has revealed that underbounded communities — urban disadvantaged unincorporated neighborhoods characterized by high-poverty and high residential density lying just outside the border of an incorporated municipality — often lack consistent access to clean and safe water. In these settings, poor water quality and inadequate infrastructure shape residents’ risk perceptions often leading to tap water mistrust. However, little is known about the broader social, political, and economic drivers of water quality in these settings and how such drivers inform the social construction of risk across different stakeholder groups. Using an underbounded African-American/Hispanic …

Evaluating Behavioral Skills Training To Teach Identification Of Choking Hazards To Substitute Caregivers, Madison L. Molve

USF Tampa Graduate Theses and Dissertations

Choking is a leading cause of mortality in children (Committee on Injury, Violence and Poison Prevention, 2010). Over half of choking injuries occur due to food, and the remaining injuries involve common household objects (Chapin et al., 2013). Although studies have been conducted assessing the use of Behavioral Skills Training (BST) to teach hazard identification in substitute caregivers (Abarca, 2021), no studies have evaluated utilizing BST to identify choking hazards specifically. Thus, this study evaluated the efficacy of using BST to teach edible and non-edible choking hazard identification to substitute caregivers following guidelines from the Home Accident Prevention Inventory Revised …

Outcomes Of A Telehealth Adaptation Of A Trauma-Based Parent Training Program, Holland Hayford

USF Tampa Graduate Theses and Dissertations

Approximately 25% of children will experience a traumatic event by the age of four. If trauma symptoms remain untreated, these traumatic experiences during early childhood can negatively impact a child’s executive functioning skills, mental health, social interactions, and relational attachments to other individuals. Due to the harmful impact of untreated trauma symptoms on children’s wellbeing and development, several evidence-based interventions have been developed. One such intervention is Smart Start: Parenting Tools for Children with Developmental Delay, Social-Emotional Concerns, and Trauma (version 5), which targets children’s disruptive behaviors and trauma symptoms, caregivers’ parenting stress, and the caregiver-child relationship. This study utilized …

Glucose Homeostasis In Human Diabetic Adipocytes: Role Of Glp1 In Sortilin Alternative Splicing, Ashley Lui

USF Tampa Graduate Theses and Dissertations

Type 2 diabetes mellitus (T2DM) is a chronic and progressive metabolic disease defined by systemic insulin resistance. The inability of cells to respond to insulin and take up glucose results in elevated blood sugar that is detrimental to the overall health of patients. There is no cure for T2DM. Identification of new targets to alleviate hyperglycemia are crucial for treatment and prevention of metabolic diseases. Adipocytes play a central role in glycemic regulation by insulin stimulated glucose uptake, storage of excess nutrients, and secretion of adipokines. Major glucose transporter-4 (Glut4) is the main transporter responsible for postprandial clearance of glucose …

Microheater Stimulation Platform For Neural Cells, Haley Royce

USF Tampa Graduate Theses and Dissertations

Electrical stimulation is the basis of many biomedical devices like cochlear implants,pacemakers, and retinal implants. In these systems, current is applied to a desired tissue to effectively stimulate it. Unfortunately, this is not localized as the current will spread through the tissue, limiting the spatial resolution. Thus, alternative forms of stimulation are needed to improve device precision and resolution. This project explores microheaters as a stimulation platform that can be easily integrated with existing biomedical devices. Microheaters produce heat via the Joule heating effect wherein electrical current is run through high resistance materials to output thermal energy. They are highly …

Ethnic-Racial Minoritized Adolescents’ Perceptions Of Cyberhate, School Connectedness, Ethnic-Racial Identity, And Life Satisfaction, Alexis Taylor

USF Tampa Graduate Theses and Dissertations

Exposure to cyberhate has become an increasing trend across social media, with approximately 64% of adolescents reporting that they have seen hate speech (Common Sense, 2018). While social media is used to connect with others via likes, posts, and shares, it also allows for hateful content to spread quickly. Cyberhate is the intentional aggression or threat towards an individual or group based on their societal group association, such as race, ethnicity, gender, sexual orientation, and religion (Wachs et al., 2020). Ethnic-racial minoritized adolescents who experience cyberhate as racial discrimination may be at increased risk of maladaptive psychosocial adjustment (Sellers et …

Complaint Patterns In Us Nursing Homes: 2013-2017, Kallol Kumar Bhattacharyya

USF Tampa Graduate Theses and Dissertations

Complaints provide valuable information to consumers about nursing homes (NHs). Complaints that are substantiated often lead to an investigation and potentially a deficiency citation. In recent years, Nursing Home Quality data show mixed results. According to some Federal reports, one of the four data sets that measure residents’ quality of care in NHs, consumer complaints, suggest that residents’ concerns over quality have increased. In contrast, the other three datasets, i.e., deficiencies through annual recertification surveys, staffing levels, and clinical quality measures, reveal potential improvement in NH quality of services. The purpose of this dissertation is to carry out analyses of …

Boredom, Interoceptive Ability, And Emotional Eating, Erica Ahlich

USF Tampa Graduate Theses and Dissertations

Emotional eating is a commonly described phenomenon reported by individuals across the weight spectrum. Not only does existing evidence suggest it is not an effective emotion regulation strategy, but emotional eating is also associated with difficulty losing weight during weight loss interventions and other negative health outcomes. The majority of existing work in the area of emotional eating has focused on the broad dimensions of negative and positive affect. Yet, there are data suggesting that different emotions appear to produce different changes in eating behaviors, suggesting the importance of investigating the influence of discrete emotions on eating. The lack of …

The Multidimensional Test Anxiety Scale: A Latent Profile Analysis And An Examination Of Measurement Invariance, Gabrielle Francis

USF Tampa Graduate Theses and Dissertations

Standardized testing is an integral part of the English and American education systems. The objectives of these tests are to evaluate students, teachers, and schools. However, this evaluation has unintended consequences, one of which is test anxiety. Over the last 50 years, there has been an increase in studies on test anxiety because of the widespread use of standardized tests (Hembree, 1988; von der Embse et al., 2019). However, two areas that have seen little attention are the measurement invariance of test anxiety scales across demographic groups, and the creation of classification standards for these test anxiety scales to increase …

Alpha Synuclein: A Therapeutic Target And Biomarker For Parkinson’S Disease, Max Chase

USF Tampa Graduate Theses and Dissertations

Parkinson’s Disease is the second most common neurodegenerative disease after Alzheimer’s Disease, and the most common motor disorder. In fact, nearly a third of those with AD have PD. A major hallmark of PD is the appearance of Lewy Bodies, proteinaceous cytoplasm inclusions, that build up and spread throughout the CNS in a prion like fashion. The major component of these Lewy Bodies is a protein called alpha-synuclein. Alpha-syn is a 14kDa protein made of 140 amino acids and found in the presynaptic ends of CNS neurons, acting as a chaperone and regulator. The protein is also found in the …

A Model-Based Fault Diagnosis In Dynamic Systems Via Asynchronous Motors System Identification Or Testing, And Control Engineering Observers, Kenelt Pierre
