An Empirical Investigation Of Network Topology On Majority Illusion, Behavior Adoption, And Polarization, Sreeja Sreekantan Nair

USF Tampa Graduate Theses and Dissertations

Social influence plays a significant role in shaping opinions and behaviors both online and inthe physical world. The ways in which we interact with others and the information we receive can significantly influence our beliefs and attitudes towards different issues. While online social media provide platforms for such interactions, the underlying network structure can impact various social influence phenomena, including majority illusion, behavior adoption, and polarization.

This dissertation examines the role of network topology in three social influence processes:majority illusion, behavior adoption, and polarization. The majority illusion refers to a perception bias that occurs when individuals believe that an opinion …

Evaluation Of Two Methods To Estimate Wet Bulb Globe Temperature From Heat Index, Stephi Pofanl

USF Tampa Graduate Theses and Dissertations

The Wet bulb globe temperature (WBGT) is a common method to evaluate environmental factors that contribute to occupational heat stress. The Heat Index (HI) is readily available as an alternative to exposure methods. They both assess the most important contributors that are air temperature and humidity. WBGT also includes radiant heat and air motion. To account for radiant heat and/or air motion, some investigators have suggested adjustments to HI. The purpose of this study is to explore two methods to estimate the usefulness of WBGT from HI.

WBGT data were collected in a variety of locations that included direct sun …

A Study Of Relationship Between Exertional Heat Illness And Heat Stress Levels, Rolando J. Fargas-Martinez

USF Tampa Graduate Theses and Dissertations

Introduction: Heat stress is clearly associated exertional heat illnesses (EHI) in workers in a number of studies. With expected increase in extreme thermal changes, an increase understanding the effects of heat stress conditions is necessary. The purpose of this study was to compare heat stress levels in a manufacturing plant to determine whether a relationship exists between heat stress level relative to the occupational exposure limit and exertional heat illness incidents.Methods: OSHA recordable heat illness cases (n=35) were collected over a three year period. Over the same period, hourly ambient Heat Index data was collected. For this manufacturing plant, heat …

Institutional And Individual Approaches To Change In Undergraduate Stem Education: Two Framework Analyses, Stephanie B. Feola

USF Tampa Graduate Theses and Dissertations

The overarching goal of this dissertation is to examine institutional change initiatives in STEM and to understand the impact of engaging with a specific change strategy on a biochemistry educator’s instructional practice. Institutional change initiatives involve executing an intentional strategy to influence teaching practices within a specific institution. This research investigates NSF-funded change initiatives at three public research universities that were focused on encouraging the adoption of evidenced-based instructional practices (EBIPs) by STEM faculty. As part of an effort to understand how the three institutions approached this task, framework analysis was performed using the initiative’s annual reports to NSF. Further …

Threats To School Safety: Examining Levels Of Community Violence And Its Relation To School-Related Threats, Dorie Ross

USF Tampa Graduate Theses and Dissertations

Despite significant media attention provided to school-based acts of violence, these tragic incidents are relatively rare across school environments, leading to increasing challenges in identifying students who may pose a threat. Previous approaches to school discipline, including policies such as zero tolerance, resulted in significant racial disparities among students who received disciplinary consequences inconsistent with the severity of their behaviors or threats. Alternatively, a relatively recent approach that emerged following a series of school shootings in the 1990s was school threat assessment, which focuses on prevention rather than prediction. While it is important to determine students who may pose a …

Development Of A Ddpcr Multiplex To Measure The Immune Response To Borrelia Burgdorferi., Kailey Marie Mccain

USF Tampa Graduate Theses and Dissertations

Zoonotic diseases account for a significant proportion of emerging infectious diseases (EIDs), with their dynamics being heavily influenced by the environment. While the effects of the environment on population-level disease dynamics have been extensively studied, there is limited research investigating the impact of the environment on individual-level disease susceptibility and transmission. This study aims to fill this gap by creating a tool to examine the variation in immune response to Borrelia burgdorferi, the causative agent of Lyme Disease, in two competent host species, Peromyscus leucopus and Peromyscus maniculatus. Two triplex droplet digital polymerase chain reaction (ddPCR) assays were developed to …

The Effects Of Integral And Incidental Emotions On The Perceived Risk Of Gun Violence, Gloria Laugalis

USF Tampa Graduate Theses and Dissertations

Fearful people are pessimistic when it comes to risk judgments and angry people areoptimistic in their risk judgments (Lerner & Keltner, 2000; 2001). Since this has been supported in studies regarding both incidental and integral emotions, the findings from incidental studies have been broadly generalized to answer research questions regarding integral emotions. This generalization was challenged when Ferrer and Ellis (2021) recently found differing effects of incidental and integral emotions of fear and anger. In this study, we examine the effects of these emotions, both incidental and integral to the target risk, on risk perception to help determine if incidental …

The study identified both internal and external factors contributing to academic procrastination, with social networking and software being the most significant external factors and disinterest and avoidance being the most significant internal factors. The participants did not identify the COVID-19 pandemic as a significant factor in academic procrastination. The study analyzed gender differences in academic procrastination among Chinese students. The pandemic had different effects on men and women, with men downplaying the concept of time and women experiencing …

The Impacts Of Disability Policy And Its Implementation On Deaf University Students: An Applied Anthropological Approach, Tailyn Marie Osorio

USF Tampa Graduate Theses and Dissertations

The Americans with Disabilities Act of 1990 (ADA) has provided legal requirement for universities to provide accommodations for all disabled students, including deaf students. The ADA is intentionally vague to allow flexibility for how institutions implement accommodations provisions. This leads to high variability across universities. Using ethnographic data from policy analysis, semi-structured interviews and focus groups with accommodations coordinators and deaf students from a large-public university, this applied anthropological study aims to investigate the impacts of policy and policy practices on the experiences of deaf students while proposing interventions informed by the coordinators and deaf students themselves.

This study is …

Preliminary Characterization And Functional Validation Of Pre-Erythrocytic Vaccine Candidates For The Malaria Parasite Plasmodium Vivax, Justin Lee Nicholas Iii

USF Tampa Graduate Theses and Dissertations

RTS,S/AS01, vaccine targeting malaria caused by Plasmodium falciparum, used in moderate to high malaria transmission, provides hope for pre-erythrocytic (PE) subunit malaria vaccine development. Despite this vaccine advance, efforts to develop an efficacious vaccine against the neglected parasite Plasmodium vivax have lagged. In addition, there exists a gap in our understanding of PE antigens that can induce broadly-neutralizing antibodies. In this dissertation, we provide the preliminary characterization of vaccine candidates targeting the PE of P. vivax. Through transcriptomic profiling data and a target product profile, we identified critical P. vivax antigens (SSP3, SPECT-1, and M2-MAEBL) that can potentially be targets …

An Analysis Of State Sex Education Policies To Explore The Inclusiveness Of School Based Sex Education, Amarah Scott

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to analyze state policies related to sex education proposed between 2018 and 2022 to determine the extent to which sex education needs of LGBTQ youth were being addressed. Previous research has shown that, on average, both abstinence-only and comprehensive sex education curricula do not include information that is relevant to LGBTQ youth. Much of the information included in sex education curricula such as pregnancy prevention and the benefits and disadvantages of condoms are most relevant to youth who identify as heterosexual. Not receiving relevant and accurate sex education puts LGBTQ youth at risk for …

Insect Classification And Explainability From Image Data Via Deep Learning Techniques, Tanvir Hossain Bhuiyan

USF Tampa Graduate Theses and Dissertations

Since the dawn of the Industrial Revolution, humanity has always tried to make labor more efficient and automated, and this trend is only continuing in the modern digital age. With the advent of artificial intelligence (AI) techniques in the latter part of the 20th century, the speed and scale with which AI has been leveraged to automate tasks defy human imagination. Many people deeply entrenched in the technology field are genuinely intrigued and concerned about how AI may change many of the ways in which humans have been living for millennia. Only time will provide the answers. This dissertation is …

The Applicability Of The Postmortem Submersion Interval Estimation Formula For Human Remains Found In Subtropical Aquatic Environments, Kara L. Dicomo

USF Tampa Graduate Theses and Dissertations

Within the past decade, several attempts have been made to standardize a method for estimating postmortem submersion intervals (PMSI); however, the majority of these studies have focused on data from a temperate climate which cannot be taken as representative of large portions of the globe. Thus, there are large portions of the earth in which the methodology from these studies may not be able to accurately estimate PMSI which has the potential to leave investigators in these other climatic zones at a disadvantage. This presentation presents a case study into the applicability of two Total Body Scoring Systems (TADS) utilized …

Variability Of Air Sampling Results Using Air-O-Cell Cassettes, Christina M. Haworth

USF Tampa Graduate Theses and Dissertations

No current federal or state standards for mold exposure exist, partly due to the lack of accurate methods for assessing fungal exposure. Exposure to airborne fungal spores can result in several symptoms such as allergic rhinitis, coughing, and fatigue. Non-industrial occupational settings are common and fungal exposures may occur in these environments. The purpose of this study is to evaluate the meaningfulness of fungal spore trap results from samples collected in both a corporate office and a university classroom. Air-O-Cell cassettes with a Zefon Bio-Pump were used to collect one outdoor and three indoor samples at each location on three …

The Transformative Impact Of A Semester-Long Us-Based Gelt Course On Pre-/In-Service Teachers' Cognition And Classroom Practices, Özge Güney

USF Tampa Graduate Theses and Dissertations

As English has become a global lingua franca used by a greater number of nonnative speakers than native speakers, a focus on native speaker norms in English language teaching (ELT) has become obsolete. There has been a call to incorporate different varieties of Englishes (native, nonnative, and nativized) and related cultures in both teacher education programs and the English classroom- an approach known as Global Englishes Teacher Education (GELT). This study investigates the influence of a GELT-informed teacher education course offered at a US state university on the cognition and (future) practices of pre-/in-service teachers, which aspects of the GELT …

Initial Understanding Of Public Stigma Against Childhood Cancer Survivors, Nele Loecher

USF Tampa Graduate Theses and Dissertations

As childhood cancer survival rates climb to new records, it is increasingly important to focus on improving the psychological wellbeing of survivors living years beyond their diagnosis. One potential contributor to psychological distress for childhood cancer survivors (CCSs) is stigma. The fear of stigma can lead to CCSs concealing their identity as a CCS, which in turn can strain workplace and intimate relationships, creating a strain on CCSs’ social and work life. Additionally, the internalization of negative stereotypes or rejection of falsely positive stereotypes around cancer can exacerbate psychological distress. To establish what stereotypes and stigma CCS might be contending …

A Church Of The People: Coptic Church Building And Direction In Central New Jersey, Bishoy Garis

USF Tampa Graduate Theses and Dissertations

Building off Michael Akladios’ work on early Coptic migration and the ad hoc institutionalization of the Coptic Orthodox Church in North America, this dissertation proposes that the construction and direction of Coptic churches in Middlesex County, New Jersey was laity driven, ad hoc, reactive, and dependent on local variables. Additionally, it reveals that the creation of St. Mary’s Coptic Orthodox Church in East Brunswick, New Jersey spurred migration to the Middlesex County area and transformed their small community into a domestic and international Coptic migration center. Unlike previous scholarship that places greater attention on urban Coptic communities and transnational networks, …

The Rise Of Text Analysis: Using Machine Learning To Explain The Variation In Going Concern Accuracy, Yimei Zhang

USF Tampa Graduate Theses and Dissertations

Auditors are required to issue modified audit opinions if they have sufficient doubts about the client’s ability to continue as a going concern. These going concern opinions represent an important information resource for financial statement users to evaluate client performance, and are associated with a number of negative capital market outcomes (e.g. negative returns, increased cost of capital, etc.). Despite being used by capital market participants, going concern opinions are commonly plagued with Type I errors (false positive) and Type II errors (false negative), making them a particularly noisy measure. The purpose of this study is to determine whether machine …

The Influence Of Obesity And Lifestyle Factors On Cognition In Middle-Aged And Older Adults, Andrew J. Fiscella

USF Tampa Graduate Theses and Dissertations

Obesity has been linked to conditions including cardiovascular disease, cancer, and diabetes. While the relationship of these conditions with obesity is well-established, the relationship between obesity and cognitive function is murkier.

Study 1 examined the association between being overweight or obese and performance on tests of executive function and episodic memory. The possibility that overweight/obesity affects cognition differently in middle vs. older age was also examined. Data from 6,012 participants in the 2018 wave of the Health and Retirement Study (HRS) were used. Body mass index (BMI) and waist circumference were used as overweight/obesity measures. Neither BMI (p = .809) …

“We Need To Have A Place To Vent And Get Our Frustrations Out”: Addressing The Needs Of Mothering Students In Higher Education Using A Positive Deviance Framework, Melissa León

USF Tampa Graduate Theses and Dissertations

This study examined the experiences of mothering students at four different colleges using a positive deviance (PD) framework. PD is an approach that seeks to identify positive behavioral patterns that help members of a community overcome structural barriers (Gross, et al. 2017). The Positive Deviance Framework was applied to investigate how some mothering students are successful in college and how their experiences could potentially help new or struggling mothering students. Eleven mothering students were interviewed to determine what interventions could assist mothering students who lack representation in the traditional college environment, a situation that often leads to feelings of isolation. …

Contribution Of Contextual Factors And Neuropathology To Dementia, Monica E. Nelson

USF Tampa Graduate Theses and Dissertations

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that has extensive biological heterogeneity. It is not clear the extent to which this heterogeneity may be detected in participants without dementia, how it relates to incident AD dementia, and whether contextual factors may change how neuropathology relates to incident AD dementia. Therefore, this dissertation was completed using data from the Alzheimer’s Disease Neuroimaging Initiative (ADNI; n = 1,703) and the Czech Brain Aging Study (CBAS; n = 385) to address the following aims: to assess biological heterogeneity in participants without dementia, to relate this heterogeneity to incident AD dementia, and to …

Dynamical Polymer Chain Heterogeneities And Their Impacts On The Glass Transition, William Forrest Drayer

USF Tampa Graduate Theses and Dissertations

The utilization of polymeric materials has endured since prehistory, at first unknowinglyin the form of natural biopolymers such as wood and leather, culminating and continuing through the development of the plastics industry in the early twentieth century. Polymers, along with other materials including silicate glasses, readily exhibit the glass transition upon quenching: a continuous but rapid change from viscous (liquid) to elastic (solid) behavior. The physics surrounding the glass transition have been studied for over a century; while considerable progress has been made, there remains no universally accepted predictive theory of the glass transition. Modern development of glassy materials consists …

Evaluating A Behavioral Intervention For Performance Blocks In Gymnastics, Cara L. Shapiro

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to evaluate a gradual exposure and thought training treatment package to increase gymnasts’ successful completion of a performance block skill. Following baseline, the researchers implemented both a thought training procedure to alter participants’ negative thoughts into positive thoughts, and a gradual exposure procedure which included gymnastics drills that were small approximations to the performance block skill. A 2-point rating scale was used to indicate successful completion of the skills: 0= refusal, 1= the participant initiated the skill but failed to complete it successfully, 2= the participant initiated the skill and completed it successfully. Rating …

Exploring The Risk Narratives Of Transgender People Engaged In Do-It-Yourself Hormone Replacement Therapy, Brianna Rae Cusanno

USF Tampa Graduate Theses and Dissertations

This dissertation analyzed the risk narratives of transgender people engaged in do-it- yourself hormone replacement therapy. Transgender (trans) people, those whose gender identities and/or expressions defy normative constructions of gender, experience a variety of health inequities as a consequence of systemic oppression within U.S. society. Many of the health inequities observed in trans people can be traced to structural determinants, such as discrimination at home, work, and school that results in housing, food, and social instability. Yet, medical and public health researchers have often attributed trans health inequities to “high risk” behaviors in which trans people engage.

One such behavior …

Meeting Diverse Student Needs: An Examination Of A Physical Education Teacher Alumnus’ Culturally Responsive Teaching Beliefs And Their Enactment, Craigory V. Nieman

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to examine how one physical education teacher education (PETE) alumnus teaching in a CED urban school perceives culturally responsive teaching in physical education (PE), as well as how they enact it in their classes. Guided by culturally responsive teaching and self-efficacy, this study examined John, a physical education teacher education alumnus teaching in a CED urban elementary school. John completed the culturally responsive teaching self-efficacy scale (CRTSE; Siwatu, 2007), five semi-structured interviews, five reflection journal prompts, and eight voice memos over the course of 12 weeks.

An Evaluation Of Measurement Invariance Of Dsm-5 Borderline Personality Disorder Criteria Across Heterosexual, Lesbian, Gay, And Bisexual Adults, E. Elisa Carsten

USF Tampa Graduate Theses and Dissertations

There is a robust, yet poorly understood relationship between non-heterosexual orientation and borderline personality disorder (BPD), with lesbian, gay, and bisexual individuals evidencing greater BPD symptoms compared to heterosexual individuals. Recent evidence suggests possible bias in BPD diagnostic criteria leading to greater endorsement among sexual minority individuals, which hinders researchers’ ability to make valid group comparisons. The present study utilized an epidemiological sample of 35,995 men and women to evaluate the extent of differential item functioning (DIF) among BPD criteria across sexual orientation groups using a multiple indicators multiple causes (MIMIC) approach. All criteria except affective instability and emptiness indicated …

Archaeogaming And The Re-Use Of Digital Archaeological Materials: Generating Serious Games For The Villas Of Roman Sicily, Kaitlyn Kingsland

USF Tampa Graduate Theses and Dissertations

With 10 million copies sold and 500 million dollars of revenue, the 11th installment of Ubisoft’s Assassin’s Creed series, Assassin’s Creed Odyssey (2018), showed how a videogame based on ancient Greek history and archaeology can make a splash in popular culture and that the distant past can become an extinguishable source of infinite engaging gaming narratives. As pedagogic and research counterparts to videogames of this kind, serious games and archaeogames focusing on Greek and Roman civilizations move from different premises, though aspiring to the same level of success. Serious games, created for a primary purpose other than sole entertainment, have …

Geoarchaeology Of Estuarine Seascapes In Tampa Bay, Florida., Kendal R. Jackson

USF Tampa Graduate Theses and Dissertations

This dissertation investigates the geological, ecological, and archaeological histories of Tampa Bay, Florida’s largest open-water estuary system. Previous geoscientific and archaeological work has studied the evolution of Florida’s estuaries as ‘pre-anthropogenic’ ecosystems and conceptualized Indigenous maritime societies as mostly passive inhabitants of dynamic ‘natural’ environments. Further, the environmental legacies of more recent, industrial-scale estuary modification attending Florida’s 20th-century population boom have been understudied—leading to popular and scientific confusion about historical conditions. The work composing this dissertation research seeks to reconceptualize Tampa Bay as a complex mosaic of cultural seascapes that have been variously altered and modified by human societies across …

Policy And Leadership Accountability On Black Special Education Teacher Persistence, Brittany M. Holmes

USF Tampa Graduate Theses and Dissertations

There is a persistent shortage of qualified special education teachers in schools across the country. This issue is exacerbated by the need for special education teachers of color who can help serve the disproportionate number of minority students in schools. Over time, researchers and government entities, alike, have considered ways to increase the recruitment and retention efforts of Black teachers However, given the lack of investigation regarding the needs of Black teachers in special education and what encourages their persistence, efforts to increase representation have been unsuccessful. For this reason, using a qualitative methodology, the purpose of this study is …

Enhanced Methods In Forensic Mass Spectrometry For Targeted And Untargeted Drug Analysis, Dina M. Swanson

USF Tampa Graduate Theses and Dissertations

Forensic science has long used mass spectrometry for the analysis of drugsand metabolites. Traditionally, screening methods consisted of color tests or immunoassay and confirmation methods used gas chromatography with mass spectrometry, which was considered the gold standard for identification. In the last several decades, advances in liquid chromatography with mass spectrometry (LCMS) have brought this technology to the forefront of forensic drug identification. Drug identification in forensic drug chemistry and forensic toxicology has become increasingly challenging due to the rapid increase in illicit drug analogs including novel opioids such as fentanyl analogs. Traditional screening methodologies are often unable to identify …
