Gis Automated Delineation And Analysis Of Cancer Service Areas In The United States, Changzhen Wang

LSU Doctoral Dissertations

Delineating a meaningful and reliable geographic unit pertaining to cancer care is essential in examining geographic variations in cancer care for better analysis, management, and planning. Public health researchers have devoted great efforts to defining various service areas, which; however, lack scientific rigor or are unrepresentative of the highly specialized cancer care markets, and their methods have become obsolete in the era of big data and high geo-computation. This study develops the “Spatially Constrained Leiden (ScLeiden)” method, a network community detection algorithm in Geographic Information Systems (GIS), and applies it to delineate a series of coherent cancer service …

Individual Differences In The Criminogenic Effects Of Discrimination: An Exploration Of The Role Of Impulse Control And Callous-Unemotional Traits, Toni Walker

LSU Doctoral Dissertations

The association between perceived discrimination and engagement in criminal offending has been well studied, especially in samples of minority (predominantly Black, Hispanic, and Latinx) adolescents. Several theories have been developed (Social Schematic Theory) and adapted (General Strain Theory) in an attempt to explain how harmful, discriminatory experiences may have an effect on an individual’s behavior. There may be variability in how an individual responds to perceived discrimination, however, but the moderating role of personality characteristics has not been explored. Impulse control and callous-unemotional (CU) traits are both established predictors of offending and may also relate to the mechanisms that theories …

Visuomotor Rotation Adaptation And Workspace Manipulation: A Behavioral And Cognitive Emphasis, Reuben N. Addison

LSU Doctoral Dissertations

This is a three-study dissertation in which we aimed to broaden our knowledge of the mechanisms contributing to a 45° clockwise visuomotor adaptation by including variations in workspace. We provide behavioral and in one study physiological outcomes as evidence to support our conclusions. In the first experiment, we observed the adaptation of movement parameters such as pathlength, movement time, resultant velocity, and normalized jerk across groups trained with rotated visual feedback with both the left and right hands. Workspace location and hand differentially affected movement trajectory length. The group that practiced the task with their nondominant, left hand showed larger …

Evaluation Of Hippocampal Allostatic Load-Associated Factors In Animal Models Of Post-Traumatic Stress Disorder: Relevance To Human Ptsd, Dennis Parker Kelley

LSU Doctoral Dissertations

Post-traumatic stress disorder (PTSD) is associated with elevated allostatic load, nearly double the risk for metabolic syndrome, reduced hippocampal volume, and contextual memory processing deficits. Emerging evidence suggests that these stress effects may predispose individuals to the development of PTSD, and there is a known relationship between chronic stress and metabolic dysfunction. In this work, we utilized two rat models of PTSD to explore these connections. We used an acute predator odor stressor to investigate the relationship between PTSD-like behaviors and mitochondrial dysfunction in the hippocampus of rats, and we observed that conditioned place avoidance was associated with reduced mitochondrial …

The Emergence Of The Legitimacy Of Religious Healing Knowledge In Taiwan, Wei-Cheng Chiu

LSU Doctoral Dissertations

This dissertation investigates how religious healing knowledge has been defined and used by scholars, physicians, and New Agers and how religious healing knowledge emerged as a legitimate area of knowledge in Taiwan. The key position of religious healing knowledge within the entanglement between religion and spirituality is also examined. After the martial law was lifted in 1987, Taiwan’s society had rapidly diversified, and its religions were at the transition point between the old and the new. Meanwhile, the new spirituality culture was introduced into Taiwan in the 1980s and got popular in the 1990s, and it inherited the trend of …

The Relationship Between Emotion Regulation And Substance Use Treatment Attrition, Melanie Ruth Roys

LSU Doctoral Dissertations

Severe substance use disorders are characterized by chronic cycles of relapse; however, individuals who complete substance use treatment are less likely to experience relapse. Research has focused on trying to identify factors that predict treatment dropout to help improve treatment outcomes. Most of this research has focused on examining demographic and patient-specific factors, with little success in reliably predicting treatment attrition. There has been less focus on investigating transdiagnostic factors that span across discrete psychological diagnoses and demographics. The present study sought to determine if self-report and behavioral measures related to emotion regulation predicted inpatient substance use treatment dropout above …

Five Love Languages: Assessment Of Marital Satisfaction In African American Couples, Freddricka C. Lee

LSU Master's Theses

This mixed-methods study examined marital satisfaction among five (n = 10) heterosexual, African American married couples. In particular, this study examined how acknowledging a partner’s love language (Chapman, 1995) can affect these couples’ level of marital satisfaction. The participants were native to the South and ranged from 26-55 years of age. Quantitative and qualitative analysis of the data revealed couples were satisfied with their marriages. Although only marginally significant, the findings also revealed acknowledging a spouse’s love language was positively related to higher levels of marital satisfaction. Seven themes emerged throughout the interviews, namely communication; financial stability; understand a spouse’s …

Assessing The Validity Of The Estimation Of Population Affinity From The Maxillary Hard Palate: An Empirical Approach Using A Modern Forensic Sample, Christopher M. Goden

LSU Master's Theses

In response to Beathard and DiGangi’s (2020) call to action for empirical assessment of population affinity estimation methodology, this study investigates the validity of maxillary palate shape as an indicator of ancestral population affinity for human skeletal remains through the use of Elliptical Fourier Analysis (EFA) and Linear Discriminant Function Analysis (DFA). Further, this study also places emphasis on the expressed variation of palate shape within and between population groups exemplified by Principal Component Analysis (PCA) of EFA data.

Computed tomography scans of 180 individuals of Black, White, and Hispanic population affinities were obtained from the New Mexico Decedent Imaging …

Modeling Cumulative Risk During The Covid-19 Pandemic: Psychosocial And Socioeconomic Factors For Older Minority Adults, James F. Osborne Iv

LSU Master's Theses

Continued response to the sum consequences of the COVID-19 pandemic has disparately affected the physical and mental health of older minority adults in the United States. SARS-CoV-2 created an acute epidemiological crisis of public health coinciding with a chronic pandemic of accentuated psychosocial stress. Biological and socio-economic risk of morbidity and mortality follow a demographic gradient of subjectively constructed social status that disproportionally threatens older adults and minority racial/ethnic communities. Pathways to increased socio-economic and psychosocial vulnerability are multifactorial and complex. Factors of race, socio-economic status, gender, and age, each contribute to individualized profiles of vulnerability to risk exposure.

Brown's Stages Of Morphosyntactic Development Applied To The Typical Development Of Italian, Marie Laiche

LSU Master's Theses

Background: In A First Language (1973), Roger Brown called for an increase in crosslinguistic data and analysis of morphosyntax across languages as more research in this field is crucial for working out the overarching determinants of language acquisition order and for the ability to accurately compare child language acquisition across different languages. An increase in this research would benefit linguistic researchers and speech-language-pathologists offering services to or evaluating children speaking a different language or more than one language. The current study seeks to add to the field of crosslinguistic research by adapting Brown’s guidelines of English language acquisition to the …

Sexually Dimorphic Oxytocin Receptor-Expressing Neurons In The Anteroventral Periventricular Nucleus Regulates Maternal Behavior, Kaustubh Sharma

LSU Doctoral Dissertations

The neurohypophysial hormone oxytocin is involved in the regulation of social behaviors, including social recognition, pair bonding, and sex-specific parental behaviors in a variety of species. Oxytocin triggers these social behaviors by binding to oxytocin receptors (OXTR) in various parts of the brain. Oxytocin-induced sex-typical behavior, therefore, suggests a sexual dimorphic distribution of OXTR in the brain. In recent years, the oxytocin system in the brain received tremendous attention as a potential pharmacological target for treatment of many psychiatric disorders, such as anxiety, autism spectrum disorders, and even sex-specific psychiatric disorder like postpartum depression (PPD). An important problem and a …

Comparison Of High-Tech Augmentative And Alternative Communication Interfaces: Do Age And Technology Experience Matter?, Surani Gopika Nakkawita

LSU Doctoral Dissertations

Previous research has demonstrated that individuals with stroke-induced aphasia can use augmentative and alternative communication (AAC) when they cannot meet their communication needs using spoken language (Dietz, Weissling, Griffith, McKelvey, & Macke, 2014; Purdy & Van Dyke, 2011). Of the various interfaces found in the different AAC systems, the grid display and the visual scene display (VSD) have been used by individuals with aphasia (Hough & Johnson, 2009; Dietz et al., 2018). However, there is a scarcity of research examining the comparative usefulness of these interfaces.

This prospective study attempted to understand how neurologically healthy individuals of different ages and …

Reconsidering The Obstetrical Dilemma: Correlations Between Head And Pelvic Size, Kelsey Catrice Fox

LSU Master's Theses

The Obstetrical Dilemma (OD) theory has become canon in biological anthropology. The OD posits that i] dystocia results from bipedal mothers and encephalized infants, ii] contrasting selection for bipedality and obstetrics hinders locomotive efficiency, and iii] the contradicting requirement of the fetus being small enough to pass through the birth canal yet being cognitively advanced enough to cling to its mother after birth. Females, theoretically, exhibit deficient gait efficiency for the sake of successful childbirth. An obstetric advantage theory has been posited where taller individuals with a larger head size have larger pelves. If the distance between the acetabulae increases …

Exploring Effects Of Background Music In A Serious Game On Attention By Means Of Eeg Signals In Children, Fettah Kiran

LSU Master's Theses

Music and Serious Games are separately useful alternative therapy methods for helping people with a cognitive disorder, including Attention Deficit Hyperactivity Disorder (ADHD). The goal of this thesis is to explore the effect of background music on children with and without ADHD. In this study, a simple Tetris game is designed with Beethoven, Mozart music, and no-music. There are different brainwave techniques for recording; among others, the electroencephalography (EEG) allows for the most efficient use of BCI. We recorded the EEG brain signals of the regular and ADHD subjects who played the Tetris we designed according to our protocol that …

The Relationship Between The Development Of Communicative Functions In Children With Autism Spectrum Disorders, Isabelle Bankston

LSU Master's Theses

In regard to the assessment of language, it is difficult to determine exact communicative functions that are exhibited early in development that could indicate a prognostic value of verbal abilities and outcomes of children with autism spectrum disorder (ASD). The Verbal Behavioral Milestones Assessment and Placement Program (VB-MAPP, Sundberg, 2008) is frequently used in Applied Behavior Analysis for standard assessment procedures to measure development over time. The current study was designed to use the VB-MAPP to determine a relationship between certain communicative functions (i.e., mand, tact, listener responding, echoic, and intraverbal) that may suggest a correlation in growth in each …

The two goals of this research are to apply accessibility estimation methods to HIV testing facilities, and to examine the accessibility of HIV testing facilities in the BR MSA. To achieve these goals, this study uses several research methods. The data about HIV testing providers and their locations were collected through Internet searches. By means of a fieldwork, the data were checked, revealing that …

Research To Practice- Implementing Sign-Infused Intervention As A Novice Clinician, Loren Stoller

LSU Master's Theses

Speech-Language Pathologists often infuse manual signs into oral language interventions for children with various communication disorders. The current study was designed to learn more about sign-infused language intervention by examining one novice clinician’s use of signs during oral language intervention with a child diagnosed as a late talker. The researcher was the clinician, and while a novice interventionist, she was proficient in American Sign Language (ASL) and had five years of experience using ASL with others. The child was 26 months of age at the start of the study, and data collection included three pre-intervention sessions, 12 intervention sessions, and …

Life Satisfaction And Healthcare Utilization Among Immigrants To The United States, Merritt Christian Rachel Harrelson

LSU Master's Theses

Previous research suggests a relationship between life satisfaction and healthcare utilization or HCU (Habibov & Afandi, 2016; Kim, Park, Sun, Smith, & Peterson, 2014). However, no study was found that examined this relationship among elderly American immigrants. The purpose of this study was to determine whether life satisfaction is linked to HCU for this population. The researcher of the current study applied binary logistic regression to data taken from the Health and Retirement Survey to determine whether changes in life satisfaction could be linked to variance in HCU across seven domains, including hospitalization, overnight nursing home stays, doctors visits, dentist …

The Use Of Geospatial Modeling And Novel Diagnostics To Detect And Map Risk Factors Of Soil-Transmitted Helminths In Feira De Santana, Brazil, Ryan Harry Avery

LSU Doctoral Dissertations

Soil-transmitted helminth (STH) infections impact billions of people worldwide. The traditional STH control approach is a morbidity control strategy implementing mass drug administration (MDA) programs targeting school-aged children (SAC). In Brazil, this control strategy has decreased STH prevalence to less than 20% in most of the country and providing an opportunity to transition from the morbidity control program and towards a surveillance and response system geared towards STH elimination. Surveillance and response systems geared towards elimination require the implementation higher accuracy diagnostics to detect infection in low-transmission communities, surveillance of entire households, high-resolution modeling at the household-habitat scale, and targeted …

Healthcare Utilization & Health Behaviors Among Older Adults: The Role Of Insurance, Jennifer Rose Geiger

LSU Doctoral Dissertations

As the population of older adults in the U.S. continues its exponential growth, so too will the need for high-quality health and preventive services. Despite the widely acknowledged need for proactive solutions to the coming public health challenges for this rapidly expanding age cohort, healthcare providers and social work practitioners continue to lack the proper education training to serve the needs of older adults. Furthermore, these allied health professionals also frequently engage in ageist behaviors across care settings that also often employ institutionally ageist policies and procedures. As a result, older adults may be particularly at risk of negative health …
