Introduction: Working on a wildland fire can be physically and mentally taxing. Given the physical demands of the job, fitness is a key component in keeping wildland firefighters (WLFFs) healthy and safe from injury. Unfortunately little is known about physical training (PT) programs of WLFFs.

Purpose: The purpose of this study was to examine motivators and barriers to PT in WLFFs. Personal, interpersonal, organizational and environmental factors that influence PT were identified. Strategies for overcoming barriers were …

Creating Space For An Indigenous Approach To Digital Storytelling: "Living Breath" Of Survivance Within An Anishinaabe Community In Northern Michigan, Brenda K. Manuelito

Antioch University Dissertations & Theses

As Indigenous peoples, we have a responsibility to our global community to share our collective truths and experiences, but we also deserve the respect to not be objectified, essentialized, and reified. Today, we are in a period of continual Native resurgence as many of us (re)member our prayers, songs, languages, histories, teachings, everyday stories and our deepest wisdom and understanding as Indigenous peoples--we are all “living breath” and we are “all related.” For eight years, Carmella Rodriguez and I have been nDigiStorytelling across the United States and have co-created over 1,200 digital stories with over 80 tribes for Native survivance, …

The Impact Of Climate Change On Human Health, Mary Snow, Richard Snow

Publications

Climate change is impacting human health. An obvious effect of a warmer environment is more frequent and severe heat waves. During the European heat wave of 2003, there were an estimated 35,000 more deaths than normal in the first two weeks of August. Many of the deaths resulted from cardiovascular complications among the elderly. As heat waves become more commonplace in the future, so will the number of heat strokes and the onset of other cardiovascular problems. Higher summertime temperatures also increase tropospheric ozone concentrations which in turn affects people with asthma and causes lung and heart damage. Increases in …

Sound Attenuation Performance Of Fiber-Reinforced Polymer Composite Circumaural Hearing Protection Devices, Steven Christopher Augustine

USF Tampa Graduate Theses and Dissertations

Personnel who work on the flight deck of an aircraft carrier are exposed to extreme levels of jet engine noise often in excess of 140 decibels (dB). The current circumaural hearing protective devices (CAHPD) employed by flight deck crewmen are inadequate for the level of protection required for these extreme levels of noise. Fiber-reinforced thermoset polymer composite (FRPC) materials such as aramid fibers used in body armor, have high theoretical values of acoustic impedance due to a fundamentally high modulus of elasticity and may offer a superior level of hearing protection over original equipment (OE) thermoplastic CAHPDs. The objective of …

Exploring The Underlying Mechanisms Of Comorbid Adhd And Eating Disorders, Jennifer Rebecca Bleck

USF Tampa Graduate Theses and Dissertations

Evidence suggests comorbidity of ADHD and eating disorders (EDs) among females. Capitalizing on the comorbidity of ADHD and EDs and subsequent obesity could lead to improved prevention and treatment of all three conditions. However, additional information regarding the comorbidity is necessary to develop such interventions, as little is known about how or why this co-occurrence exists. A comprehensive model of the underlying mechanisms associated with comorbid ADHD and EDs is needed to improve understanding of the development of the comorbidity. Moreover, while there are gender differences within each disorder, literature is limited regarding to the comorbidity among males, leading to …

Latino Immigrant Workers’ Search For Justice After Occupational Injury, Carla Gabriela Castillo

USF Tampa Graduate Theses and Dissertations

Latino immigrants encounter an entanglement of rights and policies after occupational injury or illness. In collaboration with an immigrant worker center, ethnographic research and a survey are used to analyze injured workers’ experiences. The center uses survey results to identify common threads and systematic problems, and to explore potential direct action. Through interviews with workers and medical and legal professionals, I investigate the barriers Latino immigrants face following occupational injury or illness, how their lived experiences relate to the greater medicolegal frameworks that demarcate most formal processes of compensation and treatment, and the experiences of professionals who mediate these structures. …

Effects Of Occupational Stressors On Nurses’ Safety Performance And Well-Being: A Within-Individual Study, Xinxuan Che

USF Tampa Graduate Theses and Dissertations

Occupational stressors have been extensively studied as predictors of safety performance and employee well-being in previous research. However, many newly introduced organizational constructs that have the characteristics of an occupational stressor have rarely been studied as such, especially from a within-person perspective. The current study focused on three occupational stressors in relation to safety performance. Based on previous literature, I proposed that within individuals, compulsory citizenship behavior, illegitimate tasks, and interpersonal conflict at work as occupational stressors would have negative effects on employees well-being and safety performance through negative emotions (anger), job attitudes (job satisfaction and organizational commitment) and role …

Maternal Stress, Breastmilk Igf-1, And Offspring Growth Among Breastfeeding Mothers-Infant Pairs In The Tampa Bay Area, Lauren Michelle Gottfredson

USF Tampa Graduate Theses and Dissertations

Background: Maternal stress during utero has been shown to have negative health consequences on the offspring, including low birth weight and increased risk of adult disease. Variation in breastmilk may act as an environmental cue of maternal stress and continue to program the infant during early life. This research aimed to explore the role of breastmilk on developmental programming of the infant. Specifically, to examine how breastmilk may act as a medium for the exposure of stress between the mother and the offspring, and see if variation in insulin like growth factor-1 (IGF-1) a potential mechanism for the relationship.

Mmv Malaria Box Activity Screening In Dormant Plasmodium Falciparum Phenotypes, Sandra Galusic

USF Tampa Graduate Theses and Dissertations

The causative agent of malignant tertian malaria, Plasmodium falciparum undergoes an arrested growth phenotype of its erythrocytic stage when under drug-stress. Recent artemisinin treatment failures seem to be indicative of such induction followed by recrudescence rather than actual therapeutic failure. Likewise, P. vivax hypnozoites are the prototypic dormants and the latent infections for which they are responsible prove most difficult to treat. Dihydroartemisinin, an artemisinin-derivative, can be used to exploit this mechanism by inducing a dormant state in ring-stage P. falciparum parasites and in turn, their recovery may be used as a screening period for compounds that inhibit or foster …

Immunological Characterization Of Duffy Binding Protein Of Plasmodium Vivax, Miriam Thankam George

USF Tampa Graduate Theses and Dissertations

Plasmodium vivax Duffy binding protein (DBP) is an essential ligand for reticulocyte invasion making it a premier asexual blood stage vaccine candidate. However, strain-specific immunity due to DBPII allelic variation may complicate vaccine efficacy, suggesting that an effective DBPII vaccine needs to target immune responses to conserved epitopes that are potential targets of strain-transcending neutralizing immunity. Anti DBPII monoclonal antibodies, which were previously characterized by COS7 cell binding assay as inhibitory and non-inhibitory to DBPII-erythrocyte binding, were mapped to DBPII gene fragment libraries using phage display. Inhibitory mAb 3C9 binds to a conserved conformation-dependent epitope in subdomain 3 while non-inhibitory …

Theoretically Guided Examination Of Caregiver Strain And Its Relationship With School-Based Mental Health Services Utilization And Parent Engagement In Services, Amy Lynn Green

USF Tampa Graduate Theses and Dissertations

Broadly, the purpose of this study was to address the gaps in the knowledge base of caregiver strain through an examination of this and other theoretically related constructs in a sample of parents of high-risk youth. In the last two decades, a growing body of research has pointed to the significance of strain that can result from this caregiving experience, particularly as it relates to patterns of mental health services utilization. Despite the fact that the majority of children who receive mental health receive them from the school, few studies have examined caregiver strain in the context of school-based mental …

Situating Contraceptive Practices And Public Health Strategy In The Bronx: Perspectives From Female Youth, Healthcare Workers, And Reproductive Health Leaders, Hannah Louise Helmy

USF Tampa Graduate Theses and Dissertations

In the United States, concerns about adolescent childbearing and its perceived corollaries – negative health outcomes for mother and child, the disintegration of the nuclear family, and “over-dependence” on public resources – began to circulate widely in policy spheres and popular media in the 1970’s, resulting in a proliferation of policies, programs, and services designed to address its prevention. Although national birth rates among adolescents are currently at their lowest since peaking in the early 1990’s, this decline masks persistent and significant disparities between groups of young people by race, ethnicity, geography, and poverty level. The concomitant existence of social …

Effects Of Solids Retention Time And Feeding Frequency On Performance And Pathogen Fate In Semi-Continuous Mesophilic Anaerobic Digesters, Nathan Daniel Manser

USF Tampa Graduate Theses and Dissertations

Anaerobic digestion is a biochemical process in which organic carbon is biodegraded in an oxygen free environment through a microbial consortium. Engineered biological systems used for resource recovery often utilize anaerobic digestion to treat anthropogenic organic wastes by reclaiming the carbon as energy (methane gas) and a soil amendment (biosolids). Small-scale, or household, semi-continuous anaerobic digesters have been used in developed and developing countries for many decades to produce biogas from human and livestock waste, which is used for heating, lighting, and cooking. This application has been shown to improve the quality of life of the user. Although there is …

Effects Of Ambient Coarse, Fine, And Ultrafine Particles And Their Biological Constituents On Systemic Biomarkers: A Controlled Human Exposure Study, Ling Liu, Bruce Urch, Raymond Poon, Mieczyslaw Szyszkowicz, Mary Speck, Diane R. Gold, Amanda J. Wheeler, James A. Scott, Jeffrey R. Brook, Peter S. Thorne, Frances S. Silverman

Research outputs 2014 to 2021

Background: Ambient coarse, fine, and ultrafine particles have been associated with mortality and morbidity. Few studies have compared how various particle size fractions affect systemic biomarkers. Objectives: We examined changes of blood and urinary biomarkers following exposures to three particle sizes. Methods: Fifty healthy nonsmoking volunteers, mean age of 28 years, were exposed to coarse (2.5–10 μm; mean, 213 μg/m3) and fine (0.15–2.5 μm; mean, 238 μg/m3) concentrated ambient particles (CAPs), and filtered ambient and/or medical air. Twenty-five participants were exposed to ultrafine CAP (< 0.3 μm; mean, 136 μg/m3) and filtered medical air. Exposures lasted 130 min, separated by ≥ 2 weeks. Blood/urine samples were collected preexposure and 1 hr and 21 hr postexposure to determine blood interleukin-6 and C-reactive protein (inflammation), endothelin-1 and vascular endothelial growth factor (VEGF; vascular mediators), and malondialdehyde (lipid peroxidation); as well as urinary VEGF, 8-hydroxy-deoxy-guanosine (DNA oxidation), and malondialdehyde. Mixed-model regressions assessed pre- and postexposure differences. results: One hour postexposure, for every 100-μg/m3 increase, coarse CAP was associated with increased blood VEGF (2.41 pg/mL; 95% CI: 0.41, 4.40) in models adjusted for O3, fine CAP with increased urinary malondialdehyde in single- (0.31 nmol/mg creatinine; 95% CI: 0.02, 0.60) and two-pollutant models, and ultrafine CAP with increased urinary 8-hydroxydeoxyguanosine in single- (0.69 ng/mg creatinine; 95% CI: 0.09, 1.29) and two-pollutant models, lasting < 21 hr. Endotoxin was significantly associated with biomarker changes similar to those found with CAPs. conclusions: Ambient particles with various sizes/constituents may influence systemic biomarkers differently. Endotoxin in ambient particles may contribute to vascular mediator changes and oxidative stress.

An Assessment Of Retractions As A Measure Of Scientific Misconduct And Impact On Public Health Risks, Alison J. Abritis

USF Tampa Graduate Theses and Dissertations

Research misconduct has been generally considered a limited issue, occurring in a small percentage of research studies. Studies of the number of article retractions use retraction percentages to perpetuate the idea that research misconduct is not a common event, and use information in the retraction notice to quantify types of research misconduct and types or research error. However, retractions appear to be the wrong variable with which to assess misconduct rates and characteristics. Using final misconduct findings in hard science research from the Office of Research Integrity (ORI) for investigations closed from 1993 through 2013, the number of publications and …

Assessment Of Public Health Risks Associated With Petrochemical Emissions Surrounding An Oil Refinery, Erin L. Pulster

USF Tampa Graduate Theses and Dissertations

Refinery operations have been associated with a wide variety of atmospheric emissions consisting of criteria air pollutants, volatile organic components, hazardous air pollutants as well as other pollutants. With approximately 100 oil refineries in the Wider Caribbean region (WCR), hydrocarbons in this region pose significant environmental and human health risks. One of the oldest and largest refineries in the WCR is the Isla Refineriá, which is located on the island of Curaçao, and has been the basis of historical debates and conflict between the public and the local government over the environmental and human health risks. This research aims to …

Southern Chivalry: Perception Of Health & Environmental Justice In A Small Southern Neighborhood, Brian S. Brijbag

USF Tampa Graduate Theses and Dissertations

This paper analyzes heath risk and how it is communicated to, and understood within, a predominantly African American neighborhood in central Florida. Residents accuse the county department of public works of purposeful contamination and discrimination over a period of 30 years. I raise the questions of how risk is perceived and what roles race or class may play. I also developed a model for risk communication that includes all stakeholders. Finally, I expand the conversation of health disparities to include issues of widening gaps in perceptions of health.

This was examined by looking at the following:

1. The lack of …

The Characterization Of The Neuropathological Consequences Of Plac1 Ablation In A Mutant Mouse Model, Jacob Robert Bourgeois

USF Tampa Graduate Theses and Dissertations

Placenta-specific 1 (Plac1) is an X-linked gene that is essential for normal placental development. Previous studies have shown that Plac1 is also expressed in the fetal brain and paternally imprinted. Its expression in the fetal brain is markedly downregulated immediately after birth. Plac1 ablation predisposes Plac1-null males and X^m-X Hets (inactive maternal allele) to an increased risk of developing lethal postnatal hydrocephalus suggesting a functional role for Plac1 during embryonic development. The objective of this study was to characterize the effect of Plac1 on brain development and postnatal function. In order to address this, a …

This dissertation study utilized the National Longitudinal Study of Adolescent to Adult Health to analyze empirical relationships between social determinants of health and adolescent pregnancy. Although rates of adolescent pregnancy are at an all-time low in the United States, disparities persist. Examining relationships between the social determinants of health and adolescent pregnancy provides support for funding and interventions that expand on the current focus of individual and interpersonal level factors. Based on the Healthy People 2020 Social Determinants of Health Framework, proxy measures for social determinants of health were identified within the Add Health study and analyzed in relationship with …

Endocrine-Disrupting Compounds: Measurement In Tampa Bay, Removal From Sewage And Development Of An Estrogen Receptor Model, Monica Mion Cook

USF Tampa Graduate Theses and Dissertations

The significance of endocrine-disrupting compounds (EDCs) in the environment has only recently come to the forefront of scientific research, policy debates, water utilities management and public awareness. EDCs have the ability to interfere with the normal functioning of the endocrine system of humans and other animals. Numerous chemicals are included in the class of compounds known as EDCs, and exposure is widespread. These compounds are found in a variety of environmental matrices (e.g., marine and freshwater systems, sediment, soil), transported there primarily through sewage effluent discharge and recycling of sewage sludge for topical fertilizer use. This transport to the environment …

Pathogenic Policy: Health-Related Consequences Of Immigrant Policing In Atlanta, Ga, Nolan Sean Kline

USF Tampa Graduate Theses and Dissertations

Multilayered immigration enforcement regimes comprising state and federal statutes and local police practices demand research on their social and health-related consequences. This dissertation explores the multiple impacts of immigrant policing: sets of laws and police activities that make undocumented immigrants more visible to authorities and increase their risk of deportation. Examining immigrant policing through a multi-sited framework and drawing from principles of engaged anthropology, findings from this dissertation suggest how immigrant policing impacts undocumented immigrants' overall wellbeing, health providers' professional practice, and reveals troubles with safety net medical care. Interviews and participant observation experiences suggest how immigrant policing perpetuates a …

Hpv Vaccine Decision-Making Among Male Sexual Minorities: An Integrative Theoretical Framework For Vaccine Promotion, Christopher W. Wheldon

USF Tampa Graduate Theses and Dissertations

Men who have sex with men (MSM) are at increased risk of anal cancer as a result of anal HPV infection. Routine HPV vaccination is recommended for all MSM up through age 26; however, vaccine uptake among this population is low. The Integrative Model of Behavioral Prediction (IM) was used to identify, describe, and explain psychosocial factors related to HPV vaccine decision-making for young MSM. A sequential mixed-methods approach consisting of semi-structured interviews, a quantitative survey, and a qualitative open-ended survey was used to address the following aims: (1) Determine salient outcome, normative, efficacy, and control beliefs related to HPV-vaccination …
