Retinotopic Patterns Of Functional And Structural Connectivity In V1, Sara Sims Jan 2019

Retinotopic Patterns Of Functional And Structural Connectivity In V1, Sara Sims

All ETDs from UAB

Vision is important for our everyday life, but we use our central vision differently than our peripheral vision. For example, we use central vision to read and peripheral vision when getting the gist of a scene. Different functions of central and peripheral vision suggest that information from central vision may be processed differently from that in peripheral vision. A previous functional magnetic resonance imaging (MRI) connectivity study suggested reliable differences in connections between centrally- and peripherally-representing visual cortex, and those differences follow well-established networks. Central-representing cortex was preferentially connected to regions belonging to the fronto-parietal (FP) net-work, mid-peripheral was generally …


A Scalable Nearline Disk Archive Storage Architecture For Extreme Scale High Performance Computing, Hampton Walker Haddock Jan 2019

A Scalable Nearline Disk Archive Storage Architecture For Extreme Scale High Performance Computing, Hampton Walker Haddock

All ETDs from UAB

Parallel file systems that exploit Redundant Arrays of Inexpensive Devices (RAID) as the mechanism for greater resilience are primarily intended to provide high bandwidth and low latency. Quantifying and studying the trade-offs among reduced run time (bandwidth and latency), resilience (availability and integrity), and cost (energy and capital) is important. For instance, distributing the checksums of RAID systems appears in conflict with the canonical parallel access patterns in high performance computing such as long sequential reads, random access, and checkpoint operations. Choices consequently have to be made between performance, concurrency, latency, energy, capital, integrity and availability of the data for …

Genomic Insight Into The Gut Microbiome Of The Sea Urchins Lytechinus Variegatus And Strongylocentrotus Purpuratus Revealed Distinct Community Compositions And Their Metabolic Profiles, Joseph Antoine Hakim

All ETDs from UAB

For over 500 million years, our planet’s self-replicating prokaryotes have colonized multicellular host organisms, forging complex interdependent relationships under the selective pressures of the natural environment. Recently, the use of high-throughput sequencing (HTS) technology targeting metacommunity DNA has uncovered the unprecedented diversity and metabolic processes of these communities. Such information has extensively been investigated in the guts of higher bilaterian organisms, such as mammals including humans. One of the early bilaterian organisms that have been linked to humans are the sea urchins, the gut microbiota of which have not been sufficiently studied. Thus, the objective of this dissertation was to …


Relationship Between Frustration Tolerance And Psychological Self-Regulatory Mechanisms In Weight Loss Maintenance, Samantha Kaytana Henry Jan 2019

Relationship Between Frustration Tolerance And Psychological Self-Regulatory Mechanisms In Weight Loss Maintenance, Samantha Kaytana Henry

All ETDs from UAB

The present study investigated the relevance of frustration tolerance and other psychological regulation factors (e.g., trait mindfulness, executive function) to long-term weight maintenance. Using a cross-sectional design, participants (N=91) were recruited from three behavioral weight loss interventions and categorized dichotomously (maintainer vs. regainer) based on their level of success in maintaining weight loss long term. Participants completed the Frustration Discomfort Scale (FDS), objective measures of executive functioning (EF), and self-report questionnaires. Poorer frustration tolerance was significantly associated with lower trait mindfulness, higher negative affectivity, and greater difficulties in self-reported EF. There were no differences by race or weight maintenance status. …


Perceptions Of African-American Teachers Concerning African-American Youth, D'Antranett Hicks-Stewart Jan 2019

Perceptions Of African-American Teachers Concerning African-American Youth, D'Antranett Hicks-Stewart

All ETDs from UAB

Perceptions of African American youth have been illustrated by how they are perceived on television: as deviants, criminals and unteachable. These perceptions are also illustrated in the behaviors of teachers in both inner-city and suburban schools. African American teachers in the inner-city schools have hope of changing the world for the better until they are met with difficult challenges presented by African-American students. Some students are excellent and some not so excellent. The structural environment of African-American youth can so strongly influence their behavior, that they begin to take on their perceptions. This can be seen in their choice friends, …

What Are The Factors Related To The Success Or Failure Of Adolescents Enrolled In Uab Tasc Adolescent Substance Abuse Program?, Tamesha Alicia Duesbury

All ETDs from UAB

Illicit drug use during adolescence is common. According to the National Survey on Drug Use and Health, marijuana usage and the misuse of prescription pain relievers were the main substances used during 2016. The survey reported that 4 million people age 12 and over were diagnosed with a marijuana disorder, 2.1 million an opioid use disorder, and 1.8 million with a prescription pain reliever disorder. Limited research has been conducted on adolescent substance abuse programs, yet there is a need for effective and efficient interventions. Using multiple logistic regression this study sought to identify the factors contributing to the success …


Tensor Decompositions And Rank Approximation Of Tensors With Applications, Ramin Goudarzi Karim Jan 2019

Tensor Decompositions And Rank Approximation Of Tensors With Applications, Ramin Goudarzi Karim

All ETDs from UAB

Tensor decompositions are higher-order analogues of matrix decompositions which have applications in data analysis, signal processing, machine learning and data mining. One of the most challenging problems in the tensor decomposition area is to approximate the rank of a given tensor. Unlike the matrix case there is no simple formula to bound the rank of a tensor. In fact, finding the exact rank of a tensor is an NP hard problem. In this thesis we formulate the tensor rank estimation of a tensor as an optimization problem and estimate the rank via $\ell_1$ minimization. We propose a numerical iterative method …


Laser Spectroscopy Of Atomic Gadolinium, Upendra Mani Adhikari Jan 2019

Laser Spectroscopy Of Atomic Gadolinium, Upendra Mani Adhikari

All ETDs from UAB

We investigated the hyperfine structure and isotope shift measurements on the spin-forbidden transitions of atomic gadolinium (Gd) at 726 nm and 743 nm in a hollow cathode glow discharge. The spectroscopic study of this sample will help to develop better isotope separation techniques. This also aids in narrowband laser cooling of Gd for novel dipolar physics investigations, and advances new technology in high precision devices. This was accomplished by performing optogalvanic spectroscopy inside an atomic vapor source. As a source, we have used a Gd hollow cathode discharge lamp with neon as a low-pressure buffer gas. Resonant absorption of a …


Religion, Psychological Distress, And Discrimination Among Arab Americans, Najwa Alharbi Jan 2019

Religion, Psychological Distress, And Discrimination Among Arab Americans, Najwa Alharbi

All ETDs from UAB

A growing body of research has focused on the experiences of Arab Americans post-9/11. These studies have been conducted to investigate the relationship between ethnic discrimination and mental health among Arab Americans. However, these studies show some gaps. Specifically, no study has explored the differences between Muslim and Christian Arabs after the 9/11 attacks in terms of religion, including how religious attendance influences the levels of psychological distress and discrimination among the two religious groups. This paper is dedicated to exploring religion (religious affiliation and religious attendance) as a key factor to understand the different levels of psychological distress and …


Stories From Rwandan Churches Prior To The Genocide; A Collection Of Oral Histories, Carmen Ava Lau Jan 2019

Stories From Rwandan Churches Prior To The Genocide; A Collection Of Oral Histories, Carmen Ava Lau

All ETDs from UAB

STORIES FROM RWANDAN CHURCHES PRIOR TO THE GENOCIDE: A COLLECTION OF ORAL HISTORIES CARMEN A. LAU ANTHROPOLOGY PEACE & HUMAN RTS ABSTRACT As a tragedy in which religion did not serve as demarcation between rival groups, the Rwandan Genocide provides an example of Christians killing Christians. I use interviews from 14 Rwandan survivors who were Seventh-day Adventists, a Protestant group to which both heroes and villains belonged. Based on Eisler’s Theory of Cultural Transfor-mation, I assume that narratives inform action. I examine oral histories through a frame-work that searches for elements of Girard’s Mimetic Rivalry that might have influenced Adventists …


The Weight Of Social Relationships: Social Network Analysis In An Adult Weight Loss Program, Alena Borgatti Jan 2019

The Weight Of Social Relationships: Social Network Analysis In An Adult Weight Loss Program, Alena Borgatti

All ETDs from UAB

Adult behavioral obesity interventions often show improved attendance and weight loss when delivered in a group, as opposed to individual, therapy format. However, research on the exact mechanisms through which group therapy confers additional weight loss is lacking. Pediatric obesity interventions have recently begun to utilize social network analysis (SNA) to identify structural ties that may improve adherence and weight loss; however, this research is limited and has yet to be replicated in an adult weight loss program. The current study is the first to evaluate social networks in an adult behavioral weight loss intervention. Four weight loss groups were …


Social Support And Self-Care Efficacy As Mediators Of Racial Disparities In Diabetes Health In Older Adults, Wesley Browning Jan 2019

Social Support And Self-Care Efficacy As Mediators Of Racial Disparities In Diabetes Health In Older Adults, Wesley Browning

All ETDs from UAB

Diabetes is a health problem that affects millions of Americans annually, and Black Americans have a higher prevalence with more complications than White Americans. A disparity exists between Black and White older adults living with diabetes in distress related to symptoms, treatment, and complications associated with the disease. Additionally, there are differences in levels of performing diabetes self-care behaviors between Blacks and Whites. One series of factors that may predict better diabetes self-care and diabetes distress in older adults are self-care efficacy and components of social support. This study used linear regression models to predict racial differences between Blacks and …


Peruvian Medical Students' Attitudes Toward People With Disabilities, Shane Daniel Burns Jan 2019

Peruvian Medical Students' Attitudes Toward People With Disabilities, Shane Daniel Burns

All ETDs from UAB

Patients with disabilities often interpret health care providers’ skills and facilities inadequate, are denied health care services, and report poor treatment in the medical setting. Key stakeholders in reforming this process are medical students, a demographic that currently provides services for patients with disabilities and will shape tomorrow’s health care systems. Past research has demonstrated that medical students often hold negative attitudes toward people with disabilities with much of this research being conducted in the developed world and none in Latin America. As a result, this study pursued to understand Peruvian medical students’ attitudes toward people with disabilities and how …


Modeling Stock Prices With Differential Equations, Jessica Barnett Jan 2019

Modeling Stock Prices With Differential Equations, Jessica Barnett

All ETDs from UAB

Forecasting the stock market has long been subject to speculation, especially after the global financial crisis in 2008. In this thesis, we formulate a predictive model of the trend of a chosen stock that is derived from verifiable economic tendencies (absent appropriate economic laws) that interact through a system of nonlinear delay differential equations. The system is populated inversely from current economic data and solved numerically using MATLAB. As a result, we are able to use the forecasted trend to estimate a stock’s drift in order to also incorporate the randomness of the stock market. Lastly, we compare the predictions …


Methods For The Establishment Of A Dss-Induced Ibd Model In Adult Zebrafish, Ningxiang Zeng Jan 2019

Methods For The Establishment Of A Dss-Induced Ibd Model In Adult Zebrafish, Ningxiang Zeng

All ETDs from UAB

Inflammatory Bowel Disease (IBD) is a group of idiopathic chronic inflammatory intestinal conditions. To reveal its pathogenesis, several different animal models have been established. Although no single model captures the complexity of human IBD, each model provides valuable insights into one or another major aspect of disease, and together they have led to the establishment of a generally accepted understanding for human IBD pathogenesis. Recently, zebrafish have become an important platform for IBD research, and several murine IBD outcomes have been adapted to the zebrafish. Dextran Sulfate Sodium (DSS) -induced colitis, the most widely used murine IBD model, has never …


Structural Elements Underlying The Neuroplastic Changes Produced By Constraint-Induced Movement Therapy In Chronic Stroke, Yue Zhang Jan 2019

Structural Elements Underlying The Neuroplastic Changes Produced By Constraint-Induced Movement Therapy In Chronic Stroke, Yue Zhang

All ETDs from UAB

Constraint-Induced Movement Therapy (CIMT) is a rehabilitation treatment that produces large motor function improvements in patients with chronic stroke. One of the hypothesized mechanisms by which CIMT achieves its therapeutic effect is the large functional and structural plastic changes that it produces in the brain. The goal of the present project was to determine the neural underpinnings of cortical reorganization produced by CIMT in chronic stroke using proton magnetic resonance spectroscopy (1H-MRS). Before applying the proposed 1H-MRS techniques (i.e., single voxel spectroscopy/SVS and whole brain magnetic resonance spectroscopic imaging/WB-MRSI) to evaluate longitudinal changes in brain metabolites after CIMT, it is …


Prevalence Of Drugs In Blood Alcohol Concentrations Above Versus Below 0.08% In Alabama Driving Under The Influence Cases, Charity Buggs Jan 2019

Prevalence Of Drugs In Blood Alcohol Concentrations Above Versus Below 0.08% In Alabama Driving Under The Influence Cases, Charity Buggs

All ETDs from UAB

Driving under the influence of drugs combined with alcohol has become an increasing problem in the United States. When a person provides a breath test that results in less than the 0.08% per se limit, their driving may still be impaired from drug use. Over the past decade, more blood samples from DUI cases involving motor vehicle crashes have tested positive for drugs than for alcohol. Cases with previously analyzed blood samples were taken from the Laboratory Information Management System at the Alabama Department of Forensic Sciences for statistical analysis. The aim of this study was to review reported DUI …


Predictors Of School Weapon Carrying Among Adolescents, Jonathan Adams Jan 2019

Predictors Of School Weapon Carrying Among Adolescents, Jonathan Adams

All ETDs from UAB

The presence of weapons threatens the safety of all individuals on school grounds. Emergent research suggests factors linked to school weapon carrying may stem from both within and outside the school environment; however, few efforts have been made to identify a comprehensive set of risk and protective factors associated with school weapon carrying. To address this gap, the first manuscript serves as a comprehensive, systematic review of variables associated with higher or lower likelihood an adolescent will carry weapons to school. Results indicated higher rates of weapon carrying among individuals who are male, sexual minority, children of single parents; exhibit …


Our Friendship And Our Enmity: British Imperialism And The 1921 Cairo Conference, Mary Katharine Armbrester Jan 2019

Our Friendship And Our Enmity: British Imperialism And The 1921 Cairo Conference, Mary Katharine Armbrester

All ETDs from UAB

A vital attempt at continued peace after the First World War that I chose to focus on for my thesis is the 1921 Cairo Peace Conference. The British government wanted an inexpensive peace that suited its own interests, and they used emissaries, particularly Winston Churchill, Gertrude Bell and T. E. Lawrence to maneuver the Cairo Peace Conference of 1921 to that end. This thesis discusses how after the collapse of the Ottoman Empire, the British unofficially offered the Arabs autonomy via the Hussein-McMahon letters if they gave the British support against the Turks during the Arab Revolt. The Arabs fought …


Assessment Of A Bdnf Mimetic To Improve Behavioral Deficits In Female Mecp2 Heterozygous Mice, A Model Of Rett Syndrome, Karen Nataly Ayala Baylon Jan 2019

Assessment Of A Bdnf Mimetic To Improve Behavioral Deficits In Female Mecp2 Heterozygous Mice, A Model Of Rett Syndrome, Karen Nataly Ayala Baylon

All ETDs from UAB

Rett syndrome (RTT) is a neurodevelopmental disorder representing the second most common cause of intellectual disability in women. Most RTT cases are caused by mutations in the gene coding for the transcriptional regulator Methyl-CpG-binding Protein 2 (MeCP2). The neurotrophin BDNF (Brain-Derived Neurotrophic Factor) has therapeutic potential for RTT because BDNF levels are lower in RTT autopsy brains and in Mecp2 deficient mice, while conditional Bdnf deletion results in phenotypes similar to those of Mecp2 knockout (KO) mice. In addition, Bdnf overexpression in forebrain excitatory neurons in Mecp2 KO mice significantly improved their lifespan, locomotor function, and brain weight. However, BDNF …


Impact Of Familial Chronic Illness On Adolescent Somatization, Lindsey Elliott Jan 2019

Impact Of Familial Chronic Illness On Adolescent Somatization, Lindsey Elliott

All ETDs from UAB

Somatic symptoms, or physical symptoms that do not have an identifiable organic etiology, have a prevalence of 10-30% in children. They have been associated with poor psychosocial outcomes in children, including emotional and behavioral problems, school absences, and impaired social functioning. Further, these symptoms represent a burden on the health care system as patients with somatic symptoms are frequent users of both primary care physicians and specialists. The etiology of somatic symptoms is thought to be due to a combination of biological, psychological, interpersonal, and healthcare factors. Two theories exist regarding the etiology of somatic symptoms. Brown’s integrative conceptual model …


The Relationship Of Bedside Assessment Of Orientation And Cognition To Treatment Outcome In Moderate To Severe Traumatic Brain Injury: A Growth Curve Analysis, Amber Marie Fahey Jan 2019

The Relationship Of Bedside Assessment Of Orientation And Cognition To Treatment Outcome In Moderate To Severe Traumatic Brain Injury: A Growth Curve Analysis, Amber Marie Fahey

All ETDs from UAB

Disorientation and cognitive impairment are commonly experienced in acute moderate to severe TBI patients and deficits early in recovery are predictive of worse long-term outcome. Hence, tracking recovery over time is a significant aspect of rehabilitation research. The Orientation-Log (O-log) and Cognition-Log (Cog-log) are important clinical measures used to monitor cognitive progress during treatment and previous research has shown them to be predictive of long-term outcome. This study used two-level growth curve modeling to, 1) determine the growth trajectory of orientation and cognition in persons with moderate to severe TBI in acute rehabilitation, as determined by the O-log and Cog-log, …


Utilization Of The Zebrafish Model System To Predict Effects Of Dietary Lipid Composition On Human Health, Lauren Adele Fowler Jan 2019

Utilization Of The Zebrafish Model System To Predict Effects Of Dietary Lipid Composition On Human Health, Lauren Adele Fowler

All ETDs from UAB

Obesity is a disease that encompasses the interaction of both genetics and life-style factors, and the pathology behind its development remains unclear. Specifically, defining the influence of dietary lipid intake on adiposity and metabolic health continues to be a fundamental challenge, and the use of animal models will be required to gain a full understanding of the processes contributing to diet-induced obesity in humans. The zebrafish Danio rerio has emerged as a powerful model system to study diet-induced obesity and metabolic disease in humans, while simultaneously offering multiple advantages over rodent models. This dissertation addresses multiple aspects regarding the use …

Rituals Of Reconciliation: The Use Of Peaceful Interactions To Repair Relationships, Sheila Renee Gainer

All ETDs from UAB

Reconciliation is the process by which social animals maintain valuable social relationships. It has been documented in many species including humans and nonhuman primates. While evidence of rituals has been seen in other species, the primary aim of this research is to explore how ritual behaviors are interconnected to human acts of reconciliation. Rituals are habitual activities closely linked to important events and reaffirm the identity of those who practice them as a group or a society. They are found in every society, culture and religion. In this study, rituals specifically related to reconciliation were exhibited in 27 of 138 …


Workplace Bullying Attitudes And Opinions In Local Government Employees, Regan Gaskin Jan 2019

Workplace Bullying Attitudes And Opinions In Local Government Employees, Regan Gaskin

All ETDs from UAB

Bullying is an issue that can affect children, adolescents, and adults (Gould, 2014; Schmidt, 2017). When bullying occurs in the workplace, it causes difficulty not only for victims, but for witnesses, families, and the organizations (Leymann, 1992). Workplace bullying has been defined as the “repeated mistreatment; abusive conduct that is: threatening, humiliating, or intimidating, work sabotage, or verbal abuse” (Namie, 2014). An estimated 60.3 million US workers are affected by workplace bullying, and 20 percent are victims (Namie, 2017). Workplace bullying research in the United States has focused more on the private sector, and to the author’s knowledge, there is …

All ETDs from UAB

The synthesis and characterization of a series of novel phosphine-, phosphinite, and phosphite-functionalized transition metal complexes are reported. These compounds have applications as alkene hydroformylation catalysts. The first chapter investigates the coordination of two tartaric acid derived ligands to cis-tetracarbonylmolybdenum(0) and pentacarbonyltungsten(0) metal centers. A cis-trans equilibrium was established for the molybdenum complexes and solid-state structures were obtained for both coordination geometries. The tungsten complexes were used to determine the electronic parameters of the donor ligands. The second chapter investigates a library of ligands derived from 1,2-O-isopropylideneglycerol as catalysts for the hydroformylation of styrene. Model complexes containing molybdenum, palladium, and …

Examining Naloxone Access: A Spatial Asessment Of Opioid Use In Urban And Rural Contexts, Keith Chichester

All ETDs from UAB

Background: Elements of the physical environment have been shown to influence health behaviors including drug use and overdose mortality. Throughout the opioid epidemic in the United States, rural regions have been disproportionately affected by opioid overdose. Although the relationship between the urban built environment and opioid overdose has been established, little is known as to how trends may differ in rural areas. Methods: Risk terrain modeling was used as a spatial analytical approach to assess environmental features that significantly increase the risk of opioid overdose in Jefferson County, Alabama. Spatial risk assessments were conducted for urban and rural regions as …


The Civil Rights Struggle For Black Economic Opportunity In Birmingham, Logan Montgomery Barrett Jan 2019

The Civil Rights Struggle For Black Economic Opportunity In Birmingham, Logan Montgomery Barrett

All ETDs from UAB

This thesis examines the intersection between Birmingham, Alabama’s civil rights movement and labor history. It considers the city leadership’s exploitation of black labor and the radical resistance these oppressive conditions fostered. A long civil rights struggle in Birmingham emphasizes the movement’s pursuit of economic opportunity in securing a better quality of life for the city’s African American population. Showcasing three distinct eras of Birmingham’s black freedom struggle, this thesis argues that economic justice remained at the core of the prolonged movement. During the first half of the twentieth century, the city’s black working class embraced radical influences in combating workplace …


Social Justice On Campus: Does It Really Fight Hate? An Exploratory Study, Caitlin Elizabeth Beard Jan 2019

Social Justice On Campus: Does It Really Fight Hate? An Exploratory Study, Caitlin Elizabeth Beard

All ETDs from UAB

This exploratory study expands upon information from a previously conducted pilot study involving schools from states in two regions of the United States—the Southeast and the West Coast—which compared the number of social justice organizations at four universities from every state to the number of bias incidents in each state from 2010 through 2016. While no statistically significant relationship was found, the pilot study suggested a negative relationship between the number of social justice organizations and the occurrence of hate crimes. This thesis uses data from forty-nine states and the District of Columbia to create a larger data pool consisting …


The Relationship Between Cortical Excitability And Neuropsychological Functioning In Patients With Idiopathic Generalized Epilepsies (Iges), Lauren Bolden Jan 2019

The Relationship Between Cortical Excitability And Neuropsychological Functioning In Patients With Idiopathic Generalized Epilepsies (Iges), Lauren Bolden

All ETDs from UAB

Recent advances in neurostimulation and neuromodulation techniques, such as transcranial magnetic stimulation (TMS), may offer alternative treatment options to patients with idiopathic generalized epilepsies (IGEs). In a previous study, we utilized TMS to demonstrate a relationship between increased cortical excitability (i.e. hyperexcitability), attentional dysfunction, and mood disturbance in a sample of healthy adults. In general, patients with IGEs are found to exhibit cortical hyperexcitability, cognitive dysfunction, and mood problems; however, a relationship between these variables in IGEs has not yet been investigated. Importantly, patients with treatment-resistant IGEs (trIGEs) are shown to demonstrate greater cortical excitability, cognitive deficits, and mood problems …
