Examining The Social Validity Of Parent Training: Post-Participation Parent Perceptions And Reflections Of Group Triple P, Nycole C. Kauk Jul 2022

Examining The Social Validity Of Parent Training: Post-Participation Parent Perceptions And Reflections Of Group Triple P, Nycole C. Kauk

USF Tampa Graduate Theses and Dissertations

Child behavior problems are highly prevalent and impactful on the child and their family system, bringing both short-term and long-term consequences (Sanders, 2012). Many risk factors for child behavior problems are modifiable via the use of Behavioral Family Interventions, such as behavioral parent training programs (Kazdin, 1991). Behavioral Family Interventions (BFI) modify factors within the family system to minimize modifiable risk factors and engineer protective factors to produce behavior change (Kazdin, 1991). While several manualized behavioral parenting interventions exist, the Triple P parenting program is one of the most researched and effective programs used internationally, particularly the Level 4 package; …

A Convergent Approach To Aqueous Lead (Pb) Mitigation Of A Supplemental Self-Supply Shallow Groundwater Source Accessed By Handpumps In Madagascar, Adaline Marie Buerck

USF Tampa Graduate Theses and Dissertations

The World Health Organization (WHO) has consistently listed lead (Pb) as one of the ten chemicals of major public health concern. Though the toxic nature of lead has been known since the 20th century it is still utilized in a wide variety of products due to its favorable properties. Exposure to lead still accounts for approximately 900,000 deaths annually and disproportionately impacts those in low- and middle-income countries (LMIC) due to a variety of reasons such as poverty, malnutrition, and lack of knowledge on the toxic nature of lead. Lead exposure routes include air, soil, dust, diet, and water. Though …


The Integration Of Positive Psychology And Positive Behavioral Interventions & Supports To Improve Minoritized Students' Social, Emotional, And Behavioral Outcomes, Jasmine L. Gray Jun 2022

The Integration Of Positive Psychology And Positive Behavioral Interventions & Supports To Improve Minoritized Students' Social, Emotional, And Behavioral Outcomes, Jasmine L. Gray

USF Tampa Graduate Theses and Dissertations

This study aimed to examine the effectiveness of a culturally adapted 9-session group positive psychology intervention with and without an added peer reporting intervention on student levels of social, emotional, and behavioral functioning. Many studies have evaluated either school-wide positive behavioral interventions and supports (SWPBIS) or positive psychology interventions (PPIs) in isolation, but very few studies have examined the extent to which combining these interventions and approaches may promote complete mental health. The Well-Being Promotion Program is a multitarget positive psychology intervention that has been evaluated in both elementary and middle school populations (Roth et al., 2017; Lenz et al., …


Promoting Subjective Well-Being In Middle School: Role Of Internalizing And Externalizing Behaviors In A Targeted Positive Psychology Intervention, Letty Langton Dileo Jun 2022

Promoting Subjective Well-Being In Middle School: Role Of Internalizing And Externalizing Behaviors In A Targeted Positive Psychology Intervention, Letty Langton Dileo

USF Tampa Graduate Theses and Dissertations

In a dual-factor model, complete mental health entails average-to-high subjective well-being (SWB, happiness) and few internalizing and externalizing behaviors (IEB, mental illness). Although positive psychology interventions (PPIs) have been shown to increase middle school students’ SWB, more research is needed to understand how baseline IEB influences post-intervention outcomes. The current study examined the effect of baseline IEB on SWB outcomes for 122 middle school students who participated in the Well-Being Promotion Program (WBPP). The WBPP is a 10-week, small group, school-based PPI for students with low SWB, as identified from universal screening of life satisfaction. The dataset analyzed is part …


Two Essays In Applied Microeconomics: Retirement, Income Inequalities, And Other Economic Indicators Of Health And Life Satisfaction, Zahra Akbari Jun 2022

Two Essays In Applied Microeconomics: Retirement, Income Inequalities, And Other Economic Indicators Of Health And Life Satisfaction, Zahra Akbari

USF Tampa Graduate Theses and Dissertations

The following proposal includes two essays in applied microeconomics. The first essay studied the relationship between income differences among siblings and the health outcomes of the individuals. Health inequalities and the factors associated with them have been a significant interest of health economists. Among those factors that can lead to health differences in adulthood, many studies have studied financial status. There are still many questions about these factors which should be answered in this area, especially about the adulthood income relative to a reference group and how it can be related to differences in adulthood health. The main goal of …

Nonparametric Estimation Of Transition Probabilities In Illness-Death Model Based On Ranked Set Sampling, Ying Ma Jun 2022

Nonparametric Estimation Of Transition Probabilities In Illness-Death Model Based On Ranked Set Sampling, Ying Ma

USF Tampa Graduate Theses and Dissertations

The ranked set sampling (RSS) design is applied widely in agriculture, environmental science, and medical research where the exact measurements of sampling units is costly, but sampling units can be ranked by a correlated concomitant variable. RSS is usually a cost-efficient alternate to simple random sampling (SRS) for selecting more representative samples. This study presents a novel methodology to investigate the nonparametric estimation of transition probabilities in illness-death model using the RSS design. We study the Aalen–Johansen estimator of transition probabilities in illness-death Markov model based on RSS design under random right censoring time and propose nonparametric estimators of the …


Japan’S Covid 19 Infection Rate: A Focus On Tokyo Neighborhoods, Lauren Koerner Jun 2022

Japan’S Covid 19 Infection Rate: A Focus On Tokyo Neighborhoods, Lauren Koerner

USF Tampa Graduate Theses and Dissertations

This thesis asks, are neighborhood demographic and economic variables connected to COVID-19 infection rates in Tokyo, Japan? I hypothesize that variation in urbanization and neighborhood demographics account for Japan’s low, though not uniform COVID-19 infection rates. This thesis applies several anthropological perspectives: The biocultural perspective because I look at epidemiology of COVID 19 considering socio-cultural, economic, and ecological factors as well as biological susceptibilities. The critical biocultural perspective because I look at how structures of power and inequality may impact health and healthcare access. Biomedical/applied anthropology, well placed to study the current epidemiologic situation of COVID 19 in Japan and …


Outcomes Of A Periodic Exposure Assessment Of Workers At A University Campus, Logan M. Armagast Jun 2022

Outcomes Of A Periodic Exposure Assessment Of Workers At A University Campus, Logan M. Armagast

USF Tampa Graduate Theses and Dissertations

Standards promulgated by the Occupational Safety and Health Administration (OSHA)are applicable to most businesses in the private sector, however, state and local government entities are not under OSHA’s jurisdiction. Universities that receive public funding fall under the category of state and local government entities and, unless an OSHA-approved State plan explicitly states otherwise, they are not required to demonstrate compliance with OSHA standards and are not subject to OSHA inspections. Without being constrained by federal regulation, those responsible for ensuring the health and safety of employees at publicly funded universities have some leeway in their methods for evaluating the conditions …

The recency and novelty of the pandemic warrants research of many areas related to health care, including that of speech language pathology.

An online survey was completed by nine persons with aphasia and three eHelpers. Participants were recruited through a university clinic and by informational fliers through social media. Participants with aphasia qualified by having experiences with speech and …


Reelin Supplementation For The Rescue Of Fragile X Syndrome., Nicole K. Morrill Jun 2022

Reelin Supplementation For The Rescue Of Fragile X Syndrome., Nicole K. Morrill

USF Tampa Graduate Theses and Dissertations

Reelin is a large, extracellular matrix glycoprotein involved in neuronal migration during embryonic brain development and synaptic plasticity in the adult brain. Reelin consists of eight EGF-like repeats and undergoes natural cleavage at two sites, between repeats 2 and 3 and repeats 5 and 6, resulting in five naturally occurring fragments. The role of Reelin in the developing central nervous system has been extensively characterized, and loss of Reelin or disruption in the signaling cascade may contribute to the cognitive impairments seen in numerous neurodevelopmental or aging diseases such as schizophrenia, autism, depression, epilepsy, and Alzheimer’s disease. Reelin’s signaling potentiates …

Two children aged 3;10 and 5;4, with repertoires of less than 75 intelligible words were selected. A repeated acquisition experimental design was used to examine the effects of instruction on target vocabulary word learning and symbolic communication. …


The Multidimensional Test Anxiety Scale: A Latent Profile Analysis And An Examination Of Measurement Invariance, Gabrielle Francis May 2022

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 …

Exploring The Relationship Between Student Expected Engagement And Referrals To The Behavioral Intervention Team, Makenzie R. Schiemann Mar 2022

Exploring The Relationship Between Student Expected Engagement And Referrals To The Behavioral Intervention Team, Makenzie R. Schiemann

USF Tampa Graduate Theses and Dissertations

Higher education administrators are tasked with supporting and retaining students with increasing needs. These needs often include emotional and mental health issues but can worsen to include suicidality and violence toward others. Traditional campus approaches for supporting students and intervening for violence, such as counseling and campus safety, have been reactionary rather than proactive. Behavioral Intervention Teams (BITs) have emerged as a mechanism for heading off violence before it occurs while also supporting students who may never engage in violence but need support. These teams were born out of the concept that violence is preventable and have grown into a …

On The Reliability Of Wearable Sensors For Assessing Movement Disorder-Related Gait Quality And Imbalance: A Case Study Of Multiple Sclerosis, Steven Díaz Hernández

USF Tampa Graduate Theses and Dissertations

Approximately 33 million American adults had a movement disorder associated with medication use, ear infections, injury, or neurological disorders in 2008, with over 18 million people affected by neurological disorders worldwide. Physical therapists assist people with movement disorders by providing interventions to reduce pain, improve mobility, avoid surgeries, and prevent falls and secondary complications of neurodegenerative disorders. Current gait assessments used by physical therapists, such as the Multiple Sclerosis Walking Scale, provide only semi-quantitative data, and cannot assess walking quality in detail or describe how one’s walking quality changes over time. As a result, quantitative systems have grownas useful tools …


Small Heat Shock Protein 22 Preserves Neuronal Function In A Murine Model Of Tauopathy, Santiago Rodriguez Ospina Mar 2022

Small Heat Shock Protein 22 Preserves Neuronal Function In A Murine Model Of Tauopathy, Santiago Rodriguez Ospina

USF Tampa Graduate Theses and Dissertations

Proteinopathies is a family of diseases associated with the pathological aggregation of protein. There are a multitude of proteinopathies, like tauopathy and synucleinopathy that contribute to neurodegenerative diseases like Alzheimer’s disease (AD), Creutzfeldt-Jakob, Pick’s disease, Frontotemporal dementia, and Parkinson’s disease (PD). Currently, one focus of research in the field is mitigating aggregation-prone proteins contributing to disease state. One method of targeting aggregation is the use of chaperones. Chaperones are molecular machinery that help maintain homeostasis in the cells, through various roles and mechanisms, one of those methods is to regulate protein aggregation. Chaperones can achieve this by affecting protein-protein interactions, …

A Macro Social Examination Of The Relationship Between Disabilities And Crime Using Neighborhood And County Level Data, Natasha A. Baloch

USF Tampa Graduate Theses and Dissertations

Over the last few decades, there has been a consistent increase in mental illnesses in the US population. This has also lead to increased interactions of those with mental illnesses and/or disabilities with law enforcement and the criminal justice system. Despite these instances, there is limited research on the relationship between disabilities, mental health issues and crime in the large body of criminological research. Further, the current extant research is a) outside the field of Criminology, b) primarily focuses on those with only intellectual or developmental disabilities and/or c) does not examine this relationship at the macro level, despite evidence …


Inaccuracies In Patient Self-Report Of Genetic Testing Results For Hereditary Cancer Risks Could Impact Risk-Management Practices, Brittany Faye Sears Mar 2022

Inaccuracies In Patient Self-Report Of Genetic Testing Results For Hereditary Cancer Risks Could Impact Risk-Management Practices, Brittany Faye Sears

USF Tampa Graduate Theses and Dissertations

Pathogenic variants (PV) or likely pathogenic variants (LPV) in a cancer risk gene increase lifetime risks of developing cancer. National guidelines provide evidence-based recommendations on cancer risk management (CRM) strategies tailored to the cancer risks associated with PV/LPV in different genes. Emotional responses after learning of a PV/LPV have been studied as predictors of patient adherence to CRM, but less attention has been given to whether patients remember their actual genetic test results and the impact this may have on subsequent adherence to CRM. We surveyed a group of 114 participants registered with the Inherited Cancer Registry (ICARE), all of …


Bayesian Network-Based Diagnostic Support Tool With Limited Point-Of-Care Ultrasound For Work-Related Elbow Injuries, Cristina Maria Franceschini Sánchez Mar 2022

Bayesian Network-Based Diagnostic Support Tool With Limited Point-Of-Care Ultrasound For Work-Related Elbow Injuries, Cristina Maria Franceschini Sánchez

USF Tampa Graduate Theses and Dissertations

The upper extremity is commonly injured at the workplace, frequently involving the elbow. Currently, there are not many diagnostic support tools for elbow injuries. Developing a clinical decision support tool would allow for narrowing differential diagnoses and guide management steps in a timely and cost-effective manner. In a descriptive retrospective cohort study, 85 non-contrast elbow MRIs were obtained from a large Workers Compensation insurer database. MRIs were either (a) greater than 2 weeks after first clinic visit, or (b) more than 6 weeks after injury, but (c) not more than 3 months after injury. A Bayesian network-based diagnostic support tool …


Role Of Bmi1 In Acute Lung Injury, María Helena Hernández-Cuervo Mar 2022

Role Of Bmi1 In Acute Lung Injury, María Helena Hernández-Cuervo

USF Tampa Graduate Theses and Dissertations

Acute Lung Injury (ALI) is a set of signs and symptoms that lead to acute hypoxemic respiratory failure characterized by bilateral pulmonary infiltrates not attributed to cardiogenic origin. It is caused by a massive innate immune response, with the migration of white blood cells (neutrophils and macrophages principally) and a cytokine storm, followed by alterations in mitochondrial function, increase in reactive oxygen species production, and oxidative stress that in turn induces more mitochondrial damage. Several studies have shown that mitochondrial alterations are key events in the mechanism of ALI and reducing mitochondrial dysfunction could be a possible target in the …


Determining The Role Of Dendritic Cells During Response To Treatment With Paclitaxel/Anti-Tim-3, Alycia Gardner Jan 2022

Determining The Role Of Dendritic Cells During Response To Treatment With Paclitaxel/Anti-Tim-3, Alycia Gardner

USF Tampa Graduate Theses and Dissertations

Intratumoral CD103+ dendritic cells (cDC1) are required for anti-tumor immune responses. In tumors that are poorly responsive to immunotherapeutic approaches targeting T cells, targeting cDC1 represents an alternative approach that may be useful in improving patient response rates. As such, it is critical to understand cDC1 function within tumors, and what may be preventing optimal function of cDC1. TIM-3 is a receptor that is highly expressed by cDC1 in murine and human mammary tumors, and TIM-3 blocking antibodies are currently being evaluated in clinical trials for a number of solid and hematological malignancies. In order to best design combinatorial therapeutic …

Using Artificial Intelligence To Decipher Epigenetic Code Of Drug Resistance In The Deadliest Human Malaria Parasite, Samira Jahangiri Nov 2021

Using Artificial Intelligence To Decipher Epigenetic Code Of Drug Resistance In The Deadliest Human Malaria Parasite, Samira Jahangiri

USF Tampa Graduate Theses and Dissertations

Malaria remains one of the immense global public health challenges, with an estimated ~200 million cases worldwide in 2019 despite the remarkable gains in reducing this deadly disease over the past decade. The recent emergence and spread of artemisinin resistance (ART-R) in Plasmodium falciparum will increasingly impede global efforts to control and eliminate malaria. Previous studies have observed broad transcriptional changes and identified several noncoding genetic variants strongly associated with ART-R. The broad transcriptional variations suggest that the malaria parasite uses sophisticated epigenetic regulation to survive under drug pressure. Therefore, evaluating the regulatory effects of noncoding-variants in malaria parasites is …

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 …


A Biocultural Analysis Of The Impacts Of Interactions Between West Africans And Europeans During The Trans-Atlantic Trade At Elmina, Ghana, Heidi Ellen Miller Nov 2021

A Biocultural Analysis Of The Impacts Of Interactions Between West Africans And Europeans During The Trans-Atlantic Trade At Elmina, Ghana, Heidi Ellen Miller

USF Tampa Graduate Theses and Dissertations

This project utilizes a biocultural approach to assess the demographics and health of the West African population from Elmina, Ghana. Elmina, selected by the Portuguese in 1482 as the site of the first European trade fort in sub-Saharan Africa, grew from a small coastal fishing village to a large settlement over the course of more than 400 years of trade and cultural entanglement. Taken over by the Dutch and then ceded to the British, the people of Elmina navigated significant cultural changes, changes and experiences that can be detected in their skeletal remains. Bioarchaeological research concerned with the effects of …


Decisions And How Doctors Make Them: Modeling Multilevel Decision-Making Within Diagnostic Medicine, Michelle S. Kaplan Nov 2021

Decisions And How Doctors Make Them: Modeling Multilevel Decision-Making Within Diagnostic Medicine, Michelle S. Kaplan

USF Tampa Graduate Theses and Dissertations

Effective decision-making is critical and necessary for organizational success across a wide range of occupations, situations, and industries. However, decision making, by its nature, is not always a direct process of a single decision leading to a direct outcome. Rather, it can often become a multilevel process whereby one decision’s outcome leads to information that is used in subsequent larger or other types of decisions. The decision-making process then becomes progressively more complex and more difficult to navigate as these decisions compound within one another. Thus, decision-makers must find an appropriate way to approach such decisions. Understanding the multilevel nature …


Moving In Fluid: Exploring How Fishes Manipulate Water To Swim Efficiently, Nils B. Tack Nov 2021

Moving In Fluid: Exploring How Fishes Manipulate Water To Swim Efficiently, Nils B. Tack

USF Tampa Graduate Theses and Dissertations

Moving through a dense fluid such as water presents some unique challenges to minimizing energy use and maximizing performance (i.e., speed). Due to animal-fluid interactions during swimming (drag and thrust production) fish have evolved a variety of morphological structures and locomotor mechanisms. For instance, fish rely on body bending and/or fins to interact with the surrounding water such that energy can be transferred to generate thrust. Typically, this synergy promotes morphologies and behaviors aimed at enhancing propulsive efficiency and/or minimizing metabolic activity to lessen the cost of transport (COT). This work focuses on quantifying the energetic and hydromechanical benefits of …
