Critical Geospatial Data Science: Principles For Curating, Analyzing, And Sharing Geospatial Data, Daniel Beene

Geography ETDs

Critical geospatial data science (CGDS) offers principles for engaging with geospatial data, methods, and translation by pulling from critical epistemologies in geography. CGDS interrogates objective “truths” in science by actively engaging in critique of geospatial data and methodologies. Specifically, CGDS contends with the political context and motivations behind geospatial data science (GDS) while using GDS methods to understand how social-spatial arrangements manifest and are reinforced through data. CGDS explicitly aims to inform practices for criticality from within GDS and provides opportunities for multidisciplinary research that incorporates social theories, contextualizes geospatial data, and critically evaluates the effects and ethics of (under)representation …

Essays On Health, Labor, And Development Economics, Md Mohsan Khudri

Electronic Theses and Dissertations Archive

In the first essay, using data from the Panel Study of Income Dynamics, I estimate the impact of breastfeeding initiation and duration on multiple cognitive, health, and behavioral outcomes spanning early childhood through adolescence. To mitigate the potential bias, I employ a doubly robust (DR) estimation method, addressing misspecification in either the treatment or outcome models while adjusting for selection effects. My novel approach is to use and evaluate a battery of supervised machine learning (ML) algorithms to improve propensity score (PS) estimates. I demonstrate that the gradient boosting machine algorithm removes bias more effectively and minimizes other prediction errors …

Onesamp 3.0: Estimation Of Effective Population Size Via Snp Data From One Population, Aaron Hong, Rebecca Cheek, Suhashi Nihara De Silva, Kingshuk Mukherjee, Isha Yooseph, Mark Heim, David Tallmon, Christina Boucher

Faculty, Staff, and Students

The genetic effective size (Ne) is arguably one of the most important characteristics of a population as it impacts the rate of loss of genetic diversity. Methods that estimate Ne are important in population and conservation genetic studies as they quantify the risk of a population being inbred or lacking genetic diversity. Yet there are very few methods that can estimate the Ne from data from a single population and without extensive information about the genetics of the population, such as a linkage map, or a reference genome of the species of interest. We present ONeSAMP 3.0, an algorithm for …

Asmrtistry In Immersive Sound: Investigating The Effectiveness Of Immersive Sound Technologies In Eliciting Autonomous Sensory Meridian Response, Scott D. Nelson

LSU Doctoral Dissertations

Despite a wide array of immersive sound technologies available to digital media creators who specialize in making audio-visual content that aims to elicit Autonomous Sensory Meridian Response (ASMR), only a few sound reproduction modalities are widely used: mono/stereo and binaural recording. To date, nearly all research studying ASMR, a bio-sensory phenomenon wherein people feel brain tingles triggered by calming audio-visual cues, has been content to carry out ASMR studies entirely with stereo and binaural sound reproduction methods. Therefore, it stands to reason that more understanding about how diverse immersive sound modalities like wave field synthesis, or three-dimensional spatial audio for …

Performance Assessment Of Aboveground Storage Tanks During Flood Events, Md Manik Mia

LSU Doctoral Dissertations

This research addressed the performance of aboveground storage tanks (ASTs) and connected pipelines during floods. ASTs, integral to the oil and gas industry, store hazardous materials like crude oil and chemicals. Positioned near coastal regions, especially the hurricane-prone Gulf Coast, these areas are vulnerable to natural hazards such as floods and hurricanes. This vulnerability can lead to potential environmental and economic disasters, as seen with past hurricanes.
The primary objectives were to investigate AST bottom plate failure mechanisms under flood conditions, assess material failure in tank shells and bottom plates using finite element models, examine the behavior of connected pipelines, …

Navigating Identity: An Examination Of Intersectional Discrimination And Suicidal Ideation Among Lgbq Latinx Individuals, Jaclyn Pachicano

Dissertations (1934 -)

Suicide is one of the leading causes of death in the United States, with LGBQ Latinx adults showing higher risk for suicidality and related mental health outcomes. Experiences of discrimination, including heterosexism and ethnic discrimination, are often connected to increased risk for suicidal ideation. In addition to intersectional experiences of discrimination, LGBQ Latinx people often feel an incompatibility between their sexuality and ethnic identity, known as conflicts in allegiances (CIA), possibly increasing risk of suicidal ideation. It remains unclear what mechanisms connect intersectional discrimination and suicidal ideation. The current study expands on intersectional research by utilizing the Interpersonal Theory of …

Chemical And Physical Properties Of Fine Fractions From A Village Proximate To A Uranium Mine: Insights About Soil Health, Mary P. Haley

Nanoscience and Microsystems ETDs

Thousands of abandoned uranium mines (AUM) in Native American tribal lands have not been fully remediated, leaving uranium mine wastes exposed and accessible for potential erosion and transport by wind. Analyzing the metal and organic content of the fine-grained fractions in soils could uncover the impact of mine legacy on the soil health in communities that live in proximity to AUM. This study investigates the physical and chemical properties of the fine-grained fraction (μm) of soils to quantify the effect of heavy metal-bearing particulates on the soil health in the village of Paguate and within the Jackpile-Paguate AUM located on …

Diagnostic Evaluation Of Dizziness In Obstetric Triage, Annslee J. Lowe, Anna Shields

InterProfessional Education Research and Scholarship

Dizziness is a non-specific term used to describe various sensations of spinning, disequilibrium, imbalance, or near-syncope. The differential diagnosis for this symptom is rather extensive and includes potentially dangerous etiologies, which contributes to the significance of diagnostic evaluation. Dizziness is a frequent concern prompting pregnant patients to seek medical care, and the hemodynamic changes that occur in pregnancy further complicate clinical assessment in obstetric (OB) triage. While often familiar with dizziness as a symptom of hypertensive disorders of pregnancy, many OB triage providers experience uncertainty in working up other causes of dizziness. Root causes for uncertainty and the potential for …

A Systematic Review Of Implementation Fidelity Interventions For School-Based Behavior Supports In Special Education Settings, Paige C. Mesui

Theses and Dissertations

Problem behavior has been increasing in classrooms and has significantly contributed to teacher burnout. Students in special education settings have been found to demonstrate problem behaviors more than their general education peers. Schools have a responsibility to implement evidence-based behavioral support to assist students with their behavioral needs, decrease problem behavior, and increase desired behavior in the classroom. There is a relationship between the level of implementation fidelity and the effectiveness of an intervention. If there are not high levels of fidelity, the results are not expected to mimic what has been found in the research. The purpose of this …

Faculty, Staff and Student Publications

Triple-negative breast cancer (TNBC) is often treated with neoadjuvant systemic therapy (NAST). We investigated if radiomic models based on multiparametric Magnetic Resonance Imaging (MRI) obtained early during NAST predict pathologic complete response (pCR). We included 163 patients with stage I-III TNBC with multiparametric MRI at baseline and after 2 (C2) and 4 cycles of NAST. Seventy-eight patients (48%) had pCR, and 85 (52%) had non-pCR. Thirty-six multivariate models combining radiomic features from dynamic contrast-enhanced MRI and diffusion-weighted imaging had an area under the receiver operating characteristics curve (AUC) > 0.7. The top-performing model combined 35 radiomic features of relative difference between …

Using Behavioral Skills Training To Promote Online Safety Skills In Individuals With Developmental Disabilities, Robert Lynn

Theses

Abstract

Children are spending more time online, which is putting them at risk of encountering online predators. There have been attempts to minimize the occurrence of these encounters, but most of these involved instructional training and parent supervision. One alternative intervention for addressing safety skills that has been shown to be effective is behavior skills training (BST), which is a procedure based on behavior analytic literature. BST involves instructions, modeling, rehearsal, and feedback. The purpose of this study was to evaluate the effects of BST on the acquisition of online safety skills in adolescents and adults with developmental disabilities. In-situ …

Faculty, Staff and Student Publications

Background: The overall landscape of health-related quality of life (HRQoL) has not been thoroughly investigated in adolescents and young adults (AYAs) with cancer. Data are also lacking on how well HRQoL at the time of cancer diagnosis can prognosticate long-term survival in AYA survivors.

Patients and methods: We included 3,497 survivors of AYA cancer (age 15-39 years at diagnosis) who completed the Short-Form 12 Health Survey (SF-12) HRQoL questionnaire at diagnosis. Physical component summary (PCS) and mental component summary (MCS) scores were generated, with scores < 50 representing poor HRQoL. Differences in HRQoL by patient characteristics and tumor type were investigated using violin plots and t tests/analysis of variance. The effect of HRQoL on overall survival was assessed using Kaplan-Meier plots and Cox proportional hazards models.

Results: Overall mean PCS and MCS scores in this racially/ethnically diverse cohort (64% White, 19% …

Learning To Express Reward Prediction Error-Like Dopaminergic Activity Requires Plastic Representations Of Time, Ian Cone, Claudia Clopath, Harel Z Shouval

Faculty, Staff and Student Publications

The dominant theoretical framework to account for reinforcement learning in the brain is temporal difference learning (TD) learning, whereby certain units signal reward prediction errors (RPE). The TD algorithm has been traditionally mapped onto the dopaminergic system, as firing properties of dopamine neurons can resemble RPEs. However, certain predictions of TD learning are inconsistent with experimental results, and previous implementations of the algorithm have made unscalable assumptions regarding stimulus-specific fixed temporal bases. We propose an alternate framework to describe dopamine signaling in the brain, FLEX (Flexibly Learned Errors in Expected Reward). In FLEX, dopamine release is similar, but not identical …

Presence Of Pharmaceuticals And Personal Care Products In Sinkhole Lakes In West-Central Florida, Elzbieta Bialkowska-Jelinska

USF Tampa Graduate Theses and Dissertations

Pharmaceuticals and personal care products (PPCPs) are essential for human health, improving quality of life, and extending life expectancy. However, many of these chemicals have become significant environmental pollutants, particularly in lentic (lake) environments. One unintended source of PPCPs in natural environments is onsite wastewater treatment systems (OWTS), commonly known as septic tanks.

This study examines whether the seasonal variability of rainfall and soil saturation affects the assemblages and concentrations of PPCPs in a residential lake. The general premise of the dissertation was that with the onset of the wet season, PPCPs that had collected in the drainfields of the …

Gene Expression Analysis Reveals Dysregulation In Traumatic Brain Injury Leading To Tauopathy, Kristina M. Tosi

USF Tampa Graduate Theses and Dissertations

Traumatic Brain Injury (TBI) causes a cascade of detrimental events within neurons, contributing to a host of neurological diseases relating to dementia. In this study we have performed a meta-analysis comparing differentially expressed genes (DEG) in specific cell types such as neurons and microglia revealing inflammation as a common driver of neurological deficiencies post TBI. Inflammation and hypoxia are well characterized features of TBI; however, the molecular mechanisms causing tau hyperphosphorylation by tauopathy associated genes (TAG) post-TBI are currently poorly understood. Furthermore, there are limited in-vitro neuroinflammatory models that mimic primary and secondary TBI. We hypothesize that inducing hypoxia and …

The Impact Of Liberia’S Post-War Public Housing Policy On Homelessness, Bofor Rahim Toh, Ii

Homelessness among youth is a severe problem in post-war Liberia, with many sleeping in Palm Groove Cemetery and other informal housing settings in Monrovia and other parts of the country. This qualitative study explored post-war Liberia’s public housing program policy roles that professional competency and human capacity play in effectively mitigating homelessness of youth in Monrovia. Glasser’s choice theory was the theoretical framework used for this study. The research question explored how human capacity, selection eligibility, and professional competency at the National Housing Authority …

Psychedelic Experiences And Long-Term Spiritual Growth: A Systematic Review, William A. Schutt, Julie J. Exline, Kathleen C. Pait, Joshua A. Wilt

Faculty Scholarship

Psychedelic substances, which can occasion mystical experiences, are sometimes used for religious and spiritual reasons. Despite strong links between psychedelics and spirituality, no previous systematic review has investigated connections between psychedelics and indicators of long-term spiritual growth. Thus, 34 empirical studies were analyzed with 19,724 total participants from 32 independent samples. A variety of methodologies were used among the reviewed studies, and some studies included international samples. Results showed that psychedelics—especially classic psychedelics (e.g., psilocybin, LSD, and DMT)—have been studied more often in this context than other substances. Findings indicate that psychedelic use is linked with a variety of subjective …

Non-Surgical Bleeding And Transurethral Resection Of The Prostate (Turp) Syndrome After Turp Surgery: A Case Report And Literature Review, Akram M. Eraky, Sidney C. Rubenstein, Adnan Khan, Yasser Mokhtar, Nicole Gregorich

GME Publications

Patients undergoing transurethral resection of the prostate (TURP) surgery can develop TURP syndrome and post-TURP bleeding. Post-TURP bleeding can be surgical, from arteries or venous sinuses, or non-surgical, due to coagulopathy preventing clot formation. Non-surgical post-TURP bleeding may be due to high concentrations of urokinase and tissue plasminogen activator (tPA) in the urine that cause fibrinolytic changes and increase bleeding risk. Urine urokinase and tPA may have both local and systemic fibrinolytic effects that may prevent blood clot formation locally at the site of surgery, and cause fibrinolytic changes systemically through leaking into the blood stream. Another post-TURP complication that …
