Problem Recognition In Culturally Diverse Parent Mental Health Help Seeking, Grace Chen

LSU Doctoral Dissertations

There is evidence of a disparity between mental health prevalence rates in children and service utilization. Thus, many children are not receiving support for their mental health needs despite prevalent symptoms and high levels of psychopathology. This disparity is even greater for children from culturally diverse families who face unique stressors in comparison to their White peers. Given the known positive and preventative effects of early intervention, this places culturally diverse children at disproportionate risk for adverse mental health outcomes. Parents are gatekeepers responsible for responding to their child’s mental health needs. Thus, it is necessary to study the unique …

Proud Of Your Boy: Toxic Masculinity, Boyhood, And The American Musical, Aaron J. Wood

LSU Doctoral Dissertations

This project traces the cultural historiography of the phrase "boys will be boys" and examines the pattern of white male excusal it embodies through a case-study based survey of onstage depictions of boyhood in musical theatre. I argue that the generational idea of manhood as aggressive, competitive, and violent is continually reasserted through our passive acceptance of white boy violence. This dissertation looks to the musicals Newsies, West Side Story, Heathers, and Dear Evan Hansen as case studies for exploring the cultural lineage of the phrase “boys will be boys.” Like the works of Aaron Thomas, Raymond …

Structural Health Monitoring And Repair Of Welded Thermoplastic Composite Joints Using Embedded Multifunctional Films, Wencai Li

LSU Doctoral Dissertations

Thermoplastic composites (TPCs) have gained widespread use, particularly in large or integrated structural components, necessitating effective joining techniques. Fusion bonding (welding) has emerged as a suitable method for TPCs due to their ability to be reshaped through heating and cooling, eliminating the need for mechanical fasteners, long curing times, and extensive surface preparation. Among the welding techniques, ultrasonic welding (USW) stands out for its fast-cycling time and potential for automating large-scale structures, thereby reducing energy consumption. However, limited industrial applications of USW in this context require further knowledge to instill confidence in the process. Moreover, composite structures are susceptible to …

Assessing The Effects Of Live Oysters And Sampling Gear On Biodiversity Metrics Of Reef-Associated Benthic And Nekton Assemblages, Finella Campanino

LSU Master's Theses

Oysters are declining globally, resulting in an increase in oyster reef restoration, with many efforts prioritizing maintenance of reef-associated biodiversity. Understanding the role that reef-specific characteristics play in supporting biodiversity and how sampling gear influences measurements of biodiversity can inform design and management of restoration projects. I examined the relationship between live oyster volume and reef-associated benthic and nekton assemblages (hereafter reef assemblages) and how sampling gears influence our understanding of biodiversity on intertidal Crassostrea virginica reefs near Cocodrie, Louisiana. I quantified substrate characteristics, assemblages via trays, and water-column characteristics across four reefs and four seasons in 2022-2023, and compared …

No Strong Evidence Of The Protein Leverage Hypothesis In Pregnant Women With Obesity And Their Infants, Maryam Kebbe, Jasper Most, Abby D. Altazan, Leanne M. Redman

Clinical Research Faculty Publications

Objective: The goal of this study was to investigate the role of dietary protein on macronutrient and energy intake, maternal adiposity during pregnancy, and infant adiposity at birth. Methods: In 41 women with obesity, early-pregnancy (13–16 weeks) protein intake was assessed with food photography and expressed as a ratio of Estimated Average Requirements (EAR) in pregnancy for protein (0.88 g/kg/d), herein “protein balance.” Energy intake was measured by the intake-balance method, gestational weight gain as grams per week, and fat mass by a three-compartment model. Spearman correlations and linear models were computed using R version 4.1.1 (p < 0.05 considered significant). Results: Women had a mean (SD) age of 27.5 (4.8) years and a pregravid BMI of 34.4 (2.9), kg/m2, and the majority were non-White (n = 23, 56.1%). Protein balance in early pregnancy was not significantly associated with energy intake across mid and mid/late pregnancy (β = 328.7, p = 0.30 and β = 286.2, p = 0.26, respectively) or gestational weight gain (β = 117.0, p = 0.41). Protein balance was inversely associated with fat mass in early, mid, and late pregnancy (β = −10.6, p = 0.01, β = −10.4, p = 0.03, β = −10.3, p = 0.03, respectively). Protein balance did not predict infant adiposity at birth (p > 0.05). Conclusions: Low …

New Standards Versus New World: An Examination Of Select South Louisiana Teachers’ Experiences With Next Generation Science Standards In A Virtual Context, Bridget Lemoine

On March 8, 2017, the state of Louisiana’s Board of Elementary and Secondary Education approved the rewrite of the science standards to align with these national standards, and they were implemented in the middle school science classes. In March 2020, the COVID-19 pandemic began and thrust all students into the virtual learning world. The purpose of this study was twofold: to investigate certain changes made to the science standards in Louisiana and to examine how the pandemic interrupted NGSS implementation in the classroom both with teachers who were familiar with …

Large-Scale Nonequilibrium Molecular Studies Of Thermal Hydrate Dissociation, Meisam Adibifard, Olufemi Olorode

Faculty Publications

The energy content of methane hydrate reservoirs (MHRs) is at least twice that of conventional fossil fuels. So, there is considerable interest in their commercial development by heating, among other dissociation mechanisms. However, a few researchers have highlighted the potentially uncontrollable release of methane from MHRs, which could occur because of global warming. Therefore, it is crucial to understand the kinetics of thermal hydrate dissociation to safely develop these resources and prevent the release of this greenhouse gas into the environment. Although there have been several molecular studies of thermal dissociation, most of these use small simulation domains that cannot …

Institutional Rhetoric And Campus Reactions: A Multi-Method Case Study Exploring University Communication And Social Responsibility In A Racial Crisis, Rockia K. Harris

LSU Doctoral Dissertations

This case study explores how an institution in the southeastern conference (SEC) responded to racial reckonings before and after the 2020 murder of George Floyd, how students came to perceive the institution's responses and commitment to diversity and inclusion. To understand this phenomenon beyond apologia and image repair theory, the discourse of renewal theoretical framework and university social responsibility guides this dissertation. This work fills a gap in the literature on crisis communication in response to racism in higher education spaces. Using critical discourse analysis and an open-ended survey, this dissertation further explores the idea of social responsibility of institutions …

A "Rock To Lean On": Young Singers' Experiences In A Community Choir In Louisiana, Yulene Velásquez

LSU Doctoral Dissertations

The purpose of this intrinsic case study was to investigate young singers’ experiences in the Livingston Parish Children’s Choirs organization (LPCC), a community-based children’s choir program in Denham Springs, Louisiana. I investigated the impact of those experiences on the children’s lives inside and outside of the ensemble from the perspective of the artistic director and co-director, parents, and the singers themselves.

Women's Interracial Friendships: Cultivating Coalitional Possibilities Across Difference Through Dialogue, Akie Fukushige Wenk

LSU Doctoral Dissertations

In my dissertation, I thread through the macro-structure as well as micro-operations of hegemonic ideologies, namely white-supremacist capitalist cis-hetero patriarchy (hooks, 1995, Valdes, 1996), that has historically plagued the United States, eventually gaining a global reach over time. I center interracial friendship between Black and White cis-women, where I locate coalitional possibilities that begin at the grassroots level. I situate this interracial relationship within the socio-ecological system where the personal meets the social (including racialized backgrounds). I use a series of analogies to equate these ideologies as toxins in the air, water, and soil. Soil is where we can work …

Implicit Bias In School-Based Suicide Risk Assessment, Jessie Munson

LSU Doctoral Dissertations

Suicide remains a leading cause of death for youth, and the prevalence of suicidal behaviors continues to increase while demographic trends shift. Despite the considerable scope and impact of this global public health issue and robust evidence that cultural minority and gender-diverse youth are at particular risk, there is a significant dearth in the literature with respect to nonrandom variance or possible systematic error in suicide risk assessment practices. Moreover, studies related to school-based risk assessment are scarce despite the ethical and legal imperative to identify and serve at-risk youth as well as the unique ecological position of schools to …

Integrating Behavioral Research Findings With A Liberal Arts Paradigm, Jonathan Peterson

LSU Master's Theses

This paper explores the role of behavioral research in understanding the complexity and relevance of creativity. A brief history of the liberal arts and its current application is followed by a discussion of the importance of variability in generating novel and diverse responses, challenging the notion that creativity is solely a product of innate talent. The effects of reinforcement on variability, and how it relates to a complex relationship between reinforcement and the probability of variable responding leads to a discussion of how the combination of previously trained behaviors can lead to creative problem-solving, emphasizing the role of combinatory behavior …

Sportsman's Paradox: Conservationism And Social Progress In Modern Louisiana, Jacob T. Gautreaux

LSU Doctoral Dissertations

Over the nineteenth and early twentieth centuries, sportsmen increasingly identified Louisiana as a destined paradise due to the abundant flora and fauna. Confirmed in the legendary visits of Theodore Roosevelt in the early 1900s, the conception soon served a dual purpose as individuals like the Tabasco Sauce patriarch, E. A. McIlhenny, coopted the visualization as a lure for business investment into the nascent industrial interests within the coastal region of the state. However, it should be noted that in the 1930s and beyond, cultural conservationists like McIlhenny and Caroline Dormon preserved elements of under-documented cultures throughout the state, although usually …

Media Coverage Of Non-Ideologically Motivated Mass Shootings Versus Ideologically Motivated Mass Shootings And How The Media Affects College Students' Perceptions Of Mass Shootings, Jennifer L. Larose

LSU Doctoral Dissertations

While much is known about how the media covers mass shootings within the United States and how this coverage impacts the public, much remains unknown about the media and international mass shootings. To address this gap this dissertation examines the relationship between the media coverage of ideological and non-ideological mass shootings that have occurred around the world. It then examines the relationship between media consumption and perceptions of mass shootings. To this end, newspaper coverage on a sample of ten mass shootings from 2011-2021 are examined temporally using the Social Coping Model. Results show that media coverage varies across time …

With Every Name But Yours: A New Orchestration Of Clémence De Grandval's Stabat Mater, David Walters

LSU Doctoral Dissertations

Clémence de Grandval was a late-Romantic composer whose extensive body of work, high profile performances, and numerous accolades should have garnered prominent placement among her contemporaries. Yet her vast collection of orchestral, choral, operatic, and other stage works have been all but forgotten.

Grandval’s Stabat Mater counted among her most popular works. Though the extant score for choir, harmonium (or organ), and piano explicitly references orchestral accompaniment1 , none of the parts or full score are available. Rather than providing a conductor’s guide or chord-by-chord analysis of Grandval’s work, this document breathes new life into this lost masterpiece by orchestrating …
