Bilateral Nirs Measurements Of Muscle Mitochondrial Capacity: Feasibility And Repeatability, Rewais Hanna, Jigar Gosalia, Alaina Demalis, Zachary Hobson, Kevin K. Mccully, Brian A. Irving, Swapan Mookerjee, Giampietro L. Vairo, David N. Proctor

Faculty Publications

Background: Non-invasive determination of mitochondrial capacity via near infrared spectroscopy (NIRS) typically involves voluntary exercise of a single muscle group followed by as many as 26 brief ischemic cuff occlusions to determine a single recovery rate constant (k). Purpose: To determine the within- and between-visit repeatability of a shortened bilateral NIRS protocol, and to establish the feasibility of hamstring k measurements. Methods: Sixteen young (eight women, eight men; 22 ± 3 years) active adults underwent a bilateral electrical stimulation protocol in which multiple (n = 4) measurements of k for the vastus lateralis (VL) and medial hamstring (MH) muscles were …

Physical Fitness Spurts In Childhood: A Study In Boys, Sara Pereira, Fernando Garbeloto, Eduardo Guimarães, Carla Santos, Adam Baxter-Jones, Go Tani, Duarte Freitas, Alcibíades Bustamante, Peter T. Katzmarzyk, José Maia

Population and Public Health Science Faculty Publications

This study aimed to (1) estimate age-at-mid-growth spurt (age-at-MGS) in Portuguese boys from two different regions—the Azores islands and Viana do Castelo, and (2) identify spurts in a variety of physical fitness (PF) components aligned by age-at-MGS in the two samples. A total of 176 (Azores, n = 91; Viana do Castelo, n = 85) boys aged 6 years old were followed annually to 10 years of age. Age-at-MGS and spurts in PF components (speed, explosive muscular strength, abdominal muscular strength, agility, and flexibility) were identified for each sample. The timing and intensities of the spurts were estimated using a …

Purpose: Calorie restriction (CR) is an effective treatment for obesity-related liver and metabolic disease. However, CR studies in individuals without obesity are needed to see if CR could delay disease onset. Liver biomarkers indicate hepatic health and are linked to cardiometabolic disease. Our aim was to examine the effects of a 2-year CR intervention on liver biomarkers in healthy individuals without obesity. Methods: The Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy (CALERIE) study was a 2-year randomized controlled trial. Overall, 218 participants (body mass index: 25.1 ± 1.7 kg/m2) were enrolled into a control group (n = …

Hybrid Modeling And Prediction Of Oyster Norovirus Outbreaks, Shima Shamkhali Chenar, Zhiqiang Deng

Faculty Publications

This paper presents a hybrid model for predicting oyster norovirus outbreaks by combining the Artificial Neural Networks (ANNs) and Principal Component Analysis (PCA) methods and using the Moderate Resolution Imaging Spectroradiometer (MODIS) satellite remote-sensing data. Specifically, 10 years (2007-2016) of cloud-free MODIS Aqua data for water leaving reflectance and environmental data were extracted from the center of each oyster harvest area. Then, the PCA was utilized to compress the size of the MODIS Aqua data. An ANN model was trained using the first 4 years of the data from 2007 to 2010 and validated using the additional 6 years of …

"The Face Of The Agency": Interviews With Death Investigators In South Louisiana, Natalie H. King

LSU Master's Theses

According to the American Board of Medicolegal Death Investigators, “the role of the medicolegal death investigator is to investigate any death that falls under the jurisdiction of the medical examiner or coroner, including all suspicious, violent, unexplained and unexpected deaths” (American Board of Medicolegal Death Investigators [ABMDI], n.d.). As such, a death investigator has a job that is highly intense and stressful at a level similar to that of doctors, nurses, emergency medical technicians (EMTs), and firefighters. The majority of the literature written about death investigators focuses on procedural issues, while there seemingly is a lack of literature focused on …

Voice Therapy: Racial Disparities In Adherence And Clinically Significant Outcomes, Amber D. Burks

LSU Master's Theses

Voice therapy is evidence-based, behavioral intervention that can reduce functional and organic voice disorders. Despite its proven effectiveness, non-adherence to voice therapy is still an issue. Research shows that an estimated 65% of patients who initiate voice therapy drop out before reaching therapeutic goals. Voice therapy outcomes are largely dependent on patients’ adherence to treatment regimens, but there is limited information concerning factors that may be associated with voice therapy adherence and therapeutic outcomes for patients who successfully complete voice therapy.

The purpose of this study was to investigate which demographic factors could be associated with higher adherence rates to …

The Arena Players, Inc.: The Oldest Continuously Operating African American Community Theatre In The United States, Alexis Michelle Skinner

LSU Doctoral Dissertations

Hay (1994) gave the Arena Players the moniker, “the oldest continuously operating African American community theatre company” in the U.S. But, if Black Theatre is increasingly found in mainstream venues in regional theatre and Broadway while Black Drama is relegated to syllabi, where is the living practice of African American, or black, community theatre? And what guarantees its survival? Craig (1980) and Fraden (1994) give voice to black critics, like Locke (1925), in co-creating objectives for black theatre during the FTP which took stage as the Negro Little Theatre continued. Hill & Hatch (2003) solidify the geographical and ideological connections …

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.

A Critical Examination Of Media Images Of The Civil Rights Movement And Their Role In Shaping Collective Memories Among Northern White Audiences, Martha Ramirez

LSU Master's Theses

Collective memory theory has been used to study a wide array of phenomena, including the media’s role in shaping collective memories of pivotal and influential events throughout society. Often when lacking direct contact and engagement, the media may shape the collective memories of audiences. As such, the current study examines prominent images presented in the media and the potential role each could have contributed to the collective memory of the 1960’s Civil Rights Movement. More specifically, this study analyzes how collective memories, which are arguably influenced by the mass media, create memories for audiences that lack direct engagement (e.g., participating …

Use Of A Zebrafish Model To Identify Anticonvulsant Properties Of Cannabinoid And Terpenoid Extracts And Mixtures, Courtney Murr

LSU Master's Theses

Epilepsy is a complex group of neurological disorders affecting approximately 65 million people worldwide. Animal models reveal the activation of cannabinoid receptor 1 and cannabinoid receptor 2 reduces the severity of seizures associated with epilepsy. Trials of phytocannabinoids in mammals demonstrate their efficacy of reducing the severity of epileptic seizures. Numerous terpenoid compounds are present in Cannabis plants but most have yet to be clinically investigated. The goal of this research was to use zebrafish (Danio rerio) to identify the potential anticonvulsive properties of phytocannabinoid and terpenoid compounds. During acute cannabinoid exposures, 7-days-post-fertilization (7 dpf) zebrafish larvae were …

How "Lyingnewspapers" Made Huey Long The Ruler Of His State: A Model Of Press-Populist Dynamics, Christina A. Georgacopoulos

LSU Master's Theses

Huey Long’s use of the phrase “lyingnewspapers” to discredit negative publicity is commonly cited as evidence of his negative relationship with the mainstream press, but he did not always hold a hostile view toward newspapers. Before the press turned against him during his enemies' attempt to impeach him as governor in 1929, newspapers were one of his central tools for political advancement. He devised strategies to attract press attention and relied on newspapers to publicize himself and propagate his ideas more frequently and consistently than he used circulars or radio broadcasts, which are commonly attributed to his political success. As …

Anxiety And Depression's Incremental Effect On Executive Functioning Deficits In Children And Adolescents, Paige Picou

LSU Master's Theses

Children and adolescents experiencing anxiety and/or depression experience impairment in a myriad of domains and often engage in maladaptive strategies that then exacerbate or prolong their current symptomology. However, there is still a paucity of research examining anxiety and depression’s impact on executive functioning in children and adolescents, and existing research is muddled with problems in how researchers both define and choose to measure executive functioning. This study aims to clarify some of the conflicting research on anxiety and depression’s impact on executive functioning by using Barkley’s hybrid theory of executive functioning to determine whether anxiety and depressive symptomology add …

Exploring Shared Leadership And Multi-Organizational Collaboration In Sport For Development And Peace, Seungmin Kang

LSU Doctoral Dissertations

Although multi-organizational collaborations have become a trend in the Sport for Development and Peace (SDP) sector, existing research remains limited to collaborations between two organizations. Further, researchers continue to report managerial challenges of the multi-organizational collaborations and emphasize leadership as a key component for achieving desired outcomes in SDP collaborations. Thus, the purpose of this research was to explore the role of shared leadership in multi-organizational SDP collaboratives. Three research questions guided this study to explore the role of shared leadership through the lived experiences of SDP practitioners: (a) How is leadership shared between members in multi-organizational SDP collaboratives?, (b) …

Preventing School Absenteeism: The Case For Relationships, Rachel Denise Pounders

LSU Master's Theses

Chronic absenteeism affects nearly 20% of high school students every year (ED, 2016). It is an indicator of students at-risk and the strongest indicator of student dropout. Poor outcomes and risk indicators associated with chronic absenteeism are well established, but little is known about factors that could mitigate chronic absenteeism among vulnerable high school students. This study explored the potential influence of teacher, counselor, and peer relationships on chronic absenteeism in students, after controlling for sex, race, and socioeconomic status. The nationally representative sample came from the National Longitudinal Study of 2009 (NSLS:09) and included 17,777 students. Data were collected …

Identity Construction In The Yoruba Group Project Abroad: Discourse Analysis Of Language Use, Tawakalitu Odunayo Lasisi

This thesis approaches Alonso’s Quijano’s conversion into Don Quijote from the point of view of a psychologist. The aim of this thesis is to explain the cognitive and psychological experiences that move Alonso Quijano to become Don Quijote and its impact in the development of our current studies of the mind. Thus, one specific question will direct my project although this question will be addressed using a multidisciplinary psychologist approach. The research question is “How can Alonso Quijano’s psychological experiences and interpretations of the real world be explained today?” This question will be addressed by referencing five episodes in the …

Innovation And Competitiveness Of The Wood Furniture Industry In Kenya, Gilbert Osoro Ototo

LSU Doctoral Dissertations

The wood furniture industry in Kenya has been growing rapidly despite a decline in domestic timber supply. Although most furniture is made locally, a larger share is increasingly being imported from other countries, creating competition for domestic manufacturers. The government aims at shifting most of the demand to domestic producers to protect the sector and create jobs. However, lack of innovation has been cited as the main cause of diminishing competitiveness of the sector. Studies have shown that innovation plays a key role in creating new products, improving production processes, and establishing better business systems.

Innovation in the furniture sector …

Neurocognitive Interactions Between Anticipatory Anxiety And Memory Encoding, Felicia M. Chaisson

LSU Master's Theses

Although acute anxiety has been shown to improve encoding of threat-relevant information, its effects on threat-neutral information are less understood. Recent research suggests that anxiety can impair subsequent recall for neutral words, particularly following practice with the recall task. Here we use event-related potentials (ERPs) to test the notion that anxiety specifically disrupts the implementation of encoding strategies—such as elaborative encoding—that tend to develop with practice. ERPs were recorded as participants studied two sets of neutral words, one of which was presented in a stressful context using the threat-of-shock paradigm (threat block), and the other in a non-threatening context (safe …

Making Room For Fat Student Affairs Professionals In Higher Education, Wesley Heath

LSU Doctoral Dissertations

Sizeism is often called the last acceptable form of prejudice in our social world. Weight discrimination has been widely documented in job searches, doctors’ offices, promotions, wage gaps, education, and even courtrooms. Despite decades of critical weight scholarship, little research has been done on fat higher education employees. Using the critical theory and the fat studies theoretical framework, this phenomenological study explores bias, prejudice, and discrimination experienced by fat student affairs professionals on college campuses. Four overarching research questions were identified and focused on the following topics: the limitations of physical space on college campuses, perceptions of available resources, stereotypes …

Intimate Rhetorics Of Networked Motherhood, Katie Nelson

LSU Doctoral Dissertations

Fundamentally pregnant bodies are understood, similarly to women’s bodies, as necessitating discipline. However, new networked forums have emerged where pregnancy is understood as affirming and having the capacity to challenge a silenced subject position. Using three case studies, the #IHadAMiscarriage Instagram page, the #TakeBackPostpartum Instagram page, and mediatized discourses surrounding Kylie Jenner’s pregnancy, this dissertation writes intimate publicity into these mediatized transgressions of pregnancy and postpartum. I argue discourses about pregnancy and postpartum in these networked spaces constitute intimate publics through the cultivation of shared affected investments and divestments in embodied experiences. These investments in the embodied experiences are crafted …

"Will God Forgive Us?": Christianity And The Climate Crisis In Auteur Cinema, Margaret Alice Parson

LSU Doctoral Dissertations

Climate change is an unavoidable and real catastrophic threat to the future of Planet Earth. This dissertation is interested in how contemporary auteur cinema draws on Christian forms to give expression to the ineffability of environmental collapse. In this rhetorical generic criticism, I discuss three recent auteur films: First Reformed (2017, directed by Paul Schrader), Interstellar (2014, directed by Christopher Nolan), and mother! (2017, directed by Darren Aronofsky). In order to best rhetorically analyze these films, I perform a generic criticism which utilizes aspects of psychoanalysis and affect theory as per the work of Gunn. Each film is …

Garden Of Ruins: Military Occupation And State Power In Civil War Louisiana, Johnathan Matthew Ward

LSU Doctoral Dissertations

Using Civil War Louisiana as its focus, I argue that military occupation and expansive state power during the US Civil War served the primary mechanisms by which national states fought the war, stabilized order, and shaped a postwar nation. While many histories of the war separate frontline combat from the domestic home front and distinguish between the policy decisions of high politics and everyday decisions on the ground, this dissertation connects the political decisions of war to the daily acts of governance and resistance in occupied Louisiana. Union occupation officials and Confederate state authorities made contingent decisions throughout the war …

The Dna Cloud: Is It Alive?, Theodoros Bargiotas

LSU Doctoral Dissertations

In this analysis, I will firstly be presenting the current knowledge concerning the materiality of the internet based Cloud, which I will henceforth be referring to as simply the Cloud. For organisation purposes I have created two umbrella categories under which I place the ongoing research in the field. Scholars have been addressing the issue of Cloud materiality through broadly two prisms: sociological materiality and geopolitical materiality. The literature of course deals with the intricacies of the Cloud based on its present ferromagnetic storage functionality. However, developments in synthetic biology have caused private tech companies and University spin-offs to flirt …

Do Black Girls Receive Later Developmental Disability Diagnoses?: Results From A National Study Of Children In The United States, Danequa Forrest

LSU Doctoral Dissertations

Abstract

This study sought to analyze if age at diagnosis of autism spectrum disorder, intellectual disability, and developmental delay varies by race and sex for children between ages 6 and 17 years old. I used data from the 2011 Survey of Pathways to Diagnosis and Services (“Pathways”), a follow-up survey to the 2009/10 National Survey of Children with Special Health Care Needs (NS-CSHCN). With this nationally representative dataset, I was able to perform ordinary least squares linear regression in Stata 13. Results determined that Black girls were diagnosed with autism spectrum disorder about two years later than White girls, nearly …

Experiences Of Hospitalization For Suicide Ideation And Suicide Attempt In Gender Diverse Adults, Alix B. Aboussouan

LSU Master's Theses

Individuals who identify as Transgender/Gender Diverse (TGD) have elevated rates of suicidal thoughts and behaviors (STBs). No studies have determined the prevalence of hospitalization for STBs in TGD adults or whether this care is viewed as helpful. Understanding hospitalization experiences may determine potential new treatment targets and training initiatives integral to developing affirming care experiences for TGD individuals. This study sought to explore the lifetime prevalence of hospitalization for suicide ideation (SI) and suicide attempt (SA) for TGD individuals, determine how helpful TGD individuals find hospitalization, and investigate demographics, gender minority stressors, or provider/hospitalization characteristics that correlate with hospitalization helpfulness …

Parental Mental Health Help Seeking: Variables Associated With Asian American Parent Help Seeking Intent, Grace L. Chen

LSU Master's Theses

There is a vast disparity between children who have mental health concerns and rates of service utilization. This disparity is even greater for children of ethnic minority populations. Understanding the factors contributing to parent help seeking behavior may help address the gap in service utilization. Asian Americans specifically have low rates of mental health service utilization among adults. However, there is limited research on parent help seeking in Asian American parents. In combination with low service utilization across children with mental health concerns, Asian American children are an at-risk population. The study aims to advance research by exploring variables relating …

The Effects Of Familial Support, Social Support, And On-Campus Involvement On Posttraumatic Stress Symptoms On Academic Achievement, Kelsey G. Coulthard

LSU Master's Theses

Research demonstrates that students with higher levels of posttraumatic stress symptoms (PTS) exhibit lower grades in college (Pereira, et al., 2018). Further, higher levels of PTS during the first semester of college leads to higher rates of withdrawing from school (Boyraz, Horne, Owens, & Armstrong, 2013). Although there is ample evidence that the association between traumatic experiences are negatively correlated with academic performance, little is known about factors that may moderate or influence the relationship. Research has determined that higher levels of social support may facilitate recovery from trauma exposure and may lessen PTS symptoms in college students (Grasso, 2011). …
