The Debate On Physician-Assisted Death In The United States: A Narrative Analysis Of Formula Stories, Rebecca Blackwell

USF Tampa Graduate Theses and Dissertations

Public policy discussions can be viewed as empirical windows into broadly shared culturalvalues and emotions of the social contexts in which the policy discussions take place. This project is a narrative analysis of the public debate on physician-assisted death (PAD), drawing from three data sources: newspaper articles, the websites of social movement organizations, and testimonies from a state legislative hearing. This analysis explores ways in which social actors deploy personal stories that contribute to shape the policy-making process by appealing to cultural beliefs and broadly shared emotions. The findings of this project constitute a contribution to the study of emotions …

Community Assessment Of Water Perceptions And Household Point-Of-Use Treatment Methods In Madagascar, Isabella Rose Silverman

USF Tampa Graduate Theses and Dissertations

One in four people around the world do not have access to safe drinking water, which means that two billion people globally lack access. In high-income countries, 0.02% of yearly deaths are attributed to unsafe water sources; however, an alarming 10.6% of deaths occur in Madagascar, for the same reason.

To achieve Sustainable Development Goal 6: Ensure access to water and sanitation for all, a collaboration between public health and engineering is critical. Within the public health sector, social marketing is commonly utilized to address a problem by using commercial marketing principles to change behavior for the good of society. …

Seasonality In Competence To Transmit West Nile Virus For A Widespread Reservoir, Kyle L. Koller

USF Tampa Graduate Theses and Dissertations

All organisms face a central conflict; a limited supply of resources must beoptimally allocated to competing biological functions. Utilizing robust immune defenses can be energetically costly;, thus, immune function is often diminished when other processes, such as reproduction, molt, or migration demand energy. As wild animals residing in temporally dynamic environments face seasonal patterns in resource availability, infectious disease risk, and environmental suitability, many species have evolved endogenous biological rhythms so that the performance of reproduction, molt, or migration and the associated trade-off with immune function be completed when doing so best promotes fitness. In turn, this demand to optimize …

Synthesis Of A Multimodal Ecological Model For Scalable, High-Resolution Arboviral Risk Prediction In Florida, Sean P. Beeman

USF Tampa Graduate Theses and Dissertations

West Nile virus (WNV) and Eastern Equine Encephalitis virus (EEEV) represent the two greatest endemic arboviral risks to the state of Florida. Currently, no approved human vaccine exists for the prevention of either virus. In the absence of a vaccine, effective disease surveillance is paramount for public health. In Florida, WNV and EEEV sentinel chicken surveillance is conducted by mosquito control programs operated at the county, municipality, or special taxing district level. This program was implemented in 1978 following human outbreaks of St. Louis Encephalitis virus (SLEV) that occurred between 1959 and 1977, with initial sentinel coops placed in proximity …

Multidimensional Well-Being Across Time Scales In Caregivers And Non-Caregivers, Victoria R. Marino

USF Tampa Graduate Theses and Dissertations

Contemporary research on informal caregiving recognizes that, though stressful, providing care for a disabled family member or friend can bring psychological benefits, such as increased meaning or purpose in life, growing closer to the care recipient, and learning new skills. Scales of eudaimonic well-being (EWB – e.g., meaning in life, personal growth, and positive relations with others) developed in positive psychology literature offer an innovative solution to incorporating caregiving benefits into between-groups comparisons of caregiver and non-caregiver well-being, which have typically focused on cross-sectional assessment of hedonic well-being (HWB – i.e., negative/positive affect and life satisfaction). Moreover, using daily using …

Predictors Of Goal Attainment Among High School Students In Accelerated Academic Curricula Receiving School-Based Motivational Interviewing Intervention, Camille E. Hanks

USF Tampa Graduate Theses and Dissertations

Students enrolled in Advanced Placement (AP) courses and International Baccalaureate (IB) programs represent a unique group of adolescents given the high demands of their rigorous coursework and the elevated stress they experience compared to peers in the general education (Suldo & Shaunessy-Dedrick, 2013). These students are often missed in traditional screening procedures that tend to identify students struggling academically or exhibiting disruptive behaviors. Fortunately, Shaunessy-Dedrick and colleagues (2021) developed a comprehensive school-based intervention program, including universal (Tier 1) and selective (Tier 2) components, which aims to support the well-being of AP/IB students. The Tier 2 component of this program (i.e., …

Feasibility Of A Virtual Group Nutrition Intervention For Adolescents With Autism Spectrum Disorder, Acadia W. Buro

USF Tampa Graduate Theses and Dissertations

Background: Youth with autism spectrum disorder (ASD) have an increased likelihood of being overweight or developing obesity. As children and adolescents with ASD exhibit problematic eating behaviors and may consume more energy-dense foods and fewer fruits and vegetables than typically developing youth, nutrition represents a modifiable obesity risk factor for adolescents with ASD, yet there is a lack of interventions to improve healthy eating and reduce the risk of obesity in this population.

Purpose: The purpose of this study was to examine the feasibility, acceptability, and preliminary efficacy of a virtual implementation of BALANCE (Bringing Adolescent Learners with Autism Nutrition …

Chorine Conversion: Biological And Water Quality Impact On Activated Carbon Block Point Of Use Filters, Horace S. Jakpa

USF Tampa Graduate Theses and Dissertations

Point-of-use (POU) activated carbon (AC) filters are ubiquitous in many U.S. households. AC can reduce concentrations of lead, other heavy metals, and mitigate taste and odor issues. However, AC filters also remove residual disinfectants, thus allowing for the proliferation of microbes in the filter. In chloraminated systems, this can lead to localized, filter-induced nitrification. Most notably, high nitrite and nitrate in drinking water can cause methemoglobinemia (blue baby syndrome) in children under the age of three, raising public health concerns.

As a control measure for nitrification within distribution systems, utilities practice periodic, short-term secondary disinfectant switches from chloramine to free …

Development And Validation Of An Isothermal Amplification Assay For Eastern Equine Encephalitis Virus, Mikayla D. Maddison

USF Tampa Graduate Theses and Dissertations

Eastern Equine Encephalitis virus (EEEV) is a neurotrophic alphavirus for which there is no effective treatment or vaccine for humans. Periodic outbreaks in the Eastern United States represent an ongoing public health problem; Florida serves as the reservoir for EEEV for the rest of the country. Reverse transcription-polymerase chain reaction (RT-PCR) is the current gold standard for molecular diagnostic testing of the presence of EEEV in vectors. However, RT-PCR is technically complex and can be difficult for mosquito control districts to utilize. In order to provide a simple, cost-effective alternative for mosquito surveillance and control, a novel one step reverse …

Serious Mental Illness In Nursing Homes: Quality Concerns, Dylan J. Jester

USF Tampa Graduate Theses and Dissertations

Objective: This dissertation is made of two academic papers followed by a chapter discussing policy implications of the findings. The objective of this dissertation is to better understand if high-serious mental illness (SMI) nursing homes (NHs) provide poorer quality of care (e.g., operationalized as staffing levels, NH Compare quality star ratings, and health deficiencies) and whether quality in high-SMI NHs is confounded by payer mix (e.g., the proportion of residents who are Medicaid-reimbursed). A modified Donabedian Structure, Process, Outcome (SPO) Model was used as the main theoretical framework.

Methods: Data came from the Certification and Survey Provider Enhanced Reports (CASPER) …

USF Tampa Graduate Theses and Dissertations

This dissertation explores how race impacts everyday food decisions and experiences among Black and White migrants in Florida, United States. The study is rooted in scholarship on food and immigration, which asserts that dietary acculturation or the “Americanization” of diets adversely affects the overall health status of migrant populations in the U.S. To date, the majority of this literature has focused on the experiences of Latinx migrants and has not centered race in its analysis. Building on participant observation and semi-structured interviews (n=49) completed over a period of 13 months in the Tampa and Miami Metropolitan areas among Ethiopian and …

Mechanisms And Mitigation: Effects Of Light Pollution On West Nile Virus Dynamics, Meredith E. Kernbach

USF Tampa Graduate Theses and Dissertations

Light pollution, or the presence of unnatural light at night, is a pervasive and growing problem across the globe. While often pictured in urban centers, light pollution is far reaching and can affect seemingly safe and minimally developed environments. For example, agricultural communities with artificial lighting near facilities can generate such light pollution in rural areas. Further, streetlights and illuminated billboards along roads and highways can generate light pollution far from cities. Given how pervasive this anthropogenic stressor is, it is surprising that not much is known about how artificial light at night, or ALAN, affects humans or wildlife, especially …

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 …

Evaluating The Use Of Behavioral Skills Training To Teach Substitute Caregivers To Identify Hazards, Carlos Abarca

USF Tampa Graduate Theses and Dissertations

The leading cause of death for children across the world is unintentional injuries (UNICEF 2001). Hazards such as accessible pools, poisons, and small ingestible items are the leading causes of unintentional injuries. Behavioral interventions such as Project 12-Ways/Safe Care have been used to teach parents how to be proactive in structuring a home free of accessible hazards by teaching the parents to identify and remove hazards in their home. Though the Project 12-Ways/Safe Care model has over 30 years of literature supporting its efficacy, the model has not been tested with substitute caregivers who often play a critical role in …

USF Tampa Graduate Theses and Dissertations

Over time, there is an increased need to adopt more advanced and effective ways of disinfection. The emergence of the coronavirus-2019 (COVID-19) pandemic reminded the world on the importance of disinfection. Disinfection has been a routine in the healthcare setting. However, with the current pandemic problem, it is more prominently and persistently done in the domestic setting and other business settings beyond healthcare. As such, the use of most disinfectants and detergent wipes to achieve a near sanitized environment has become a common practice around the globe. This research presents the efficacy of disinfectant impregnated versus detergents wipes through comparison. …

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 …

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 …
