Responsible Classrooms: Unfinalizability, Responsibility, And Participatory Literacy In Secondary English Language Arts, Emma Jamilah Gist

LSU Doctoral Dissertations

This study examines participatory literacy practice in secondary English language arts classrooms. While literacy achievement in this context is often measured according to a student’s ability to receive and repeat predetermined information within the scope of mandated curricula and standardized tests, this study attends specifically to classroom literacy practice that centers authentic, unanticipated, dialogic student response. Within its consideration of literacy practice, this study applies the Bakhtinian notion of unfinalizability to consider those conditions that allow for learning experiences that are not predetermined but are rather uniquely, unpredictably, and unrepeatably co-constructed by individual students, student groups, and teachers. These unfinalizable …

A New Insight Into Fungal Cell Wall Architecture By Functional Genomics And Solid-State Nmr Along With Recent Advancements In Dynamic Nuclear Polarization For Analyzing Biomolecules, Arnab Chakraborty

LSU Master's Theses

This dissertation summarizes the findings related to the way by which supramolecular architecture of fungal cell wall changes with genetic mutation, dispensing genes responsible for biosynthesis of cell wall polysaccharides. This is necessary because without perfect picture of how supramolecular assembly changes with genetic mutation it is hard to assess new anti-fungal targets. Alongside this we have highlighted how recent advancement into Dynamic Nuclear Polarization (DNP) methods improved characterization of biomolecules both in case of labeled and unlabeled samples.

First study utilized Solid-state NMR (SSNMR) which is a non-destructive technique hence enabled us for the first time to deduce how …

Soil Salinity Estimation Over Coastal Wetlands Based On Random Forest Algorithm And Hydrological Connectivity Metric, Haochen Sui, Dawei Chen, Jiaguo Yan, Bin Li, Wei Li, Baoshan Cui

Faculty Publications

Owing to climate warming and human activities (irrigation and reservoirs), sea level rise and runoff reduction have been threatening the coastal ecosystem by increasing the soil salinity. However, short-term sparse in situ observations limit the study on the response of coastal soil salinity to external stressors and thus its effect on coastal ecosystem. In this study, based on hydrological connectivity metric and random forest algorithm (RF), we develop a coastal soil salinity inversion model with in situ observations and satellite-based datasets. Using Landsat images and ancillary as input variables, we produce a 30-m monthly grid dataset of surface soil salinity …

Mental Health Matters: Mental Health Service Utilization Among African American Emerging Adults, Tamecia Curry

LSU Doctoral Dissertations

Evidence indicates that people of color underutilize mental health services, but little is known empirically about the help-seeking behaviors of African American emerging adults. The present mixed method study utilizes a concurrent design with nested samples for the qualitative and quantitative components to examine willingness to seek help and help-seeking intentions among college students. Data was collected from four location sites including Louisiana State University (n=38), Texas State University (n=15), The University of Southern Mississippi (n=65) and Southern University and A&M College (n=3). Minority and non-minority participants completed the Willingness-To-Seek-Help Questionnaire and …

'My Name Is Peaches': Black Women's Affect In The Blues Biomyth, Taylor C. Scott

LSU Doctoral Dissertations

For this project, I am interested in the study of nuanced self-representations of Black rage that appear within African American literary traditions, specifically the blues aesthetic, wherein artists narrativize a wide spectrum of intelligent and specific emotion--not just melancholy. Blues narratives in which Black people self-represent are in direct opposition to flattened narratives of certain affective modes such as anger as a useless, backwards, pathologized, and flat feeling that appear within dominant U.S. and global iconographies. What I see in the blues aesthetic is the capacity for a multichromatic approach to studying rage and Black authorship in America. By using …

Tiempo De Hibridos, Paul Acevedo Gomez

LSU Master's Theses

Tiempo De Hibridos is a body of work that celebrates the multiplicity of my shifting identity. It navigates back and forth between two different worlds, each packing different experiences that become a crossbreed or hybrid of information. Using historical references, pop culture, and personal experiences, I create a narrative story that maneuvers through familiar and foreign spaces.

The images suggest a celebration of cultural identity, vitality, but also psychological pain. I purposely combine objects that can be perceived as conflicting, altering their function to reference elements that are both playful and painful. The viewer should question the combination of objects …

Ceramics And Life In Tandem, Katharine Lee Robbins

LSU Master's Theses

From the ground up, my work emerges slowly. As each coil is added, I am conscious of how my body is interacting with the rich red clay body. Each time I press clay between my hands, the material reacts and changes. It gives me comfort to feel a tangible response as I push my body into the clay. The cyclical process of art making becomes my daily ritual. Each step is repeated over and over again until it becomes ingrained in my body’s existence.

As I add coils to my work, particularly the large sculptures, I continuously circle around each …

It's Not All Rainbows & Glitter, Jerry B. Lockaby

LSU Master's Theses

The goal of this exhibition is to contextualize the struggles of the LGBTQ+ community by anchoring personal stories with collage and poetry to demonstrate the ongoing difficulties of growing up queer. Mixed media digitized collages have been created and paired with companion typographic treatments of poems and narratives from diverse points of view.

The word queer as a term to describe gay men, lesbians, and other non-conforming sexual identities, has evolved over the past 100 years. This evolution of the word parallels the struggles of LGBTQ+ people to achieve equal rights, marriage equality, protection in housing and employment, and an …

Unifying Text And Music: Applying Shurtleff's Twelve Guideposts To Operatic Arias For Soprano, Jamey J. Wright

LSU Doctoral Dissertations

In the present culture of operatic performance, artistry is measured not only by singers’ musical interpretation and vocal technique, but also by their ability to communicate compelling characterization. This monograph explores a helpful technique for dramatic interpretation in opera. The discipline of musical performance provides helpful guides to characterization through elements such phrasing, rhythm, harmony, and instrumentation. Techniques borrowed from the spoken theater, particularly those pioneered by Constantin Stanislavski, include the Magic If, objectives, actions, and tactics. The literature on auditioning for the theater is useful for synthesizing these techniques for singers, because audition techniques emphasize compelling characterization with …

Transitioning From Traditional In-Person Studio-Based Education Of Apparel Design Courses To Online Education During The Covid-19 Pandemic, Divya Desai

LSU Doctoral Dissertations

Due to the COVID-19 pandemic and subsequent lockdowns many post-secondary educational institutions all-around the world, including the USA, were forced to transition their teaching methods from a traditional in-person to an online teaching format starting in the spring of 2020. This research however is focused on the transitioning of university-level studio-based Apparel Design (AD) courses to an online teaching format during the spring and fall 2020 semesters. Teaching AD courses that are studio-based and that particularly require hands-on skills like hand rendering, draping, sewing, or pattern drafting, are challenging to be taught online as they require in person step-by-step guidance …

Sodium Mediates Developmentally Plastic Responses In Plants And Herbivores, Luis Santiago-Rosario

LSU Doctoral Dissertations

Sodium plays a crucial role in organismal performance, trophic-level interactions, and eco-evolutionary dynamics. For plants, sodium impacts osmoregulation, growth, and water uptake. For animals, sodium is essential influencing osmoregulatory processes, muscle and neural development, and blood regulation. My dissertation aims to disentangle why sodium mismatch affects resource-consumer interactions and its influence on morphological and behavioral plasticity. First, I identified how sodium impacts plant performance and sodium accumulation strategies. I initially focused my research on understanding how increasing substrate sodium affects plant growth and tissue sodium accumulation strategies in controlled settings using a systematic review approach. I found that saltier plants …

The Prime Aesthetic: Exploratory Research On The Relationship Between The Imprinting Of Aesthetic Dress Preferences And The Sensitive Period Of Emerging Adulthood, Jeremy Bernardoni

LSU Doctoral Dissertations

The purpose of this research was to explore the theoretical concept of Prime Aesthetic across generational cohorts through the investigation of individual aesthetic dress preferences (ADP), which are formed during the Prime of Life, and their potential influence on present-day ADP. The Prime Aesthetic concept is defined as a theoretical concept representative of the cumulative ADP imprinted from all influences during an individual’s Prime of Life. The Prime Aesthetic was derived from Holbrook and Schindler’s (1989) study on the development of musical tastes during late adolescence and early adulthood and linked to theories on imprinting during sensitive periods (Bornstein, 1989) …

Places To Live: A Multidisciplinary Approach To Modern Maya Houses In Yucatan, Mexico, Virginia J. Ochoa-Winemiller

LSU Doctoral Dissertations

In 1938, Robert C. Wauchope’s Modern Maya Houses provided the first detailed description of traditional rural housing for the Maya area. Until today, no research has attempted to test Wauchope’s notion of cultural continuity in Maya domestic architecture from the prehistoric past up to the time of his pioneering study. By examining data from three municipios located in the state of Yucatan, Mexico, I compared contemporary information collected during visits to residential areas with that published by Wauchope in 1938. An integrated approach to data gathering and analysis, that is, a combination of interviews, questionnaires, archaeological survey, and geographic information …

Oncostatin M Induces Lipolysis And Suppresses Insulin Response In 3t3-L1 Adipocytes, Jennifer L. Bailey, Hardy Hang, Anik Boudreau, Carrie M. Elks

Division of Basic Science Faculty Publications

Oncostatin M (OSM) is an immune cell-derived cytokine that is upregulated in adipose tissue in obesity. Upon binding its receptor (OSMR), OSM induces the phosphorylation of the p66 subunit of Src homology 2 domain-containing transforming protein 1 (SHC1), called p66Shc, and activates the extracellular signal-related kinase (ERK) pathway. Mice with adipocyte-specific OSMR deletion (OsmrFKO) are insulin resistant and exhibit adipose tissue inflammation, suggesting that intact adipocyte OSM–OSMR signaling is necessary for maintaining adipose tissue health. How OSM affects specific adipocyte functions is still unclear. Here, we examined the effects of OSM on adipocyte lipolysis. We treated 3T3-L1 adipocytes with OSM, …

Artemisia Dracunculus L. Ethanolic Extract And An Isolated Component, Dmc2, Ameliorate Inflammatory Signaling In Pancreatic Β-Cells Via Inhibition Of P38 Mapk, Peter Smoak, Susan J. Burke, Thomas M. Martin, Heidi M. Batdorf, Z. Elizabeth Floyd, J. Jason Collier

Division of Basic Science Faculty Publications

Non-resolving pancreatic islet inflammation is widely viewed as a contributor to decreases in β-cell mass and function that occur in both Type 1 and Type 2 diabetes. Therefore, strategies aimed at reducing or eliminating pathological inflammation would be useful to protect islet β-cells. Herein, we described the use of 2′,4′-dihydroxy-4-methoxydihydrochalcone (DMC2), a bioactive molecule isolated from an ethanolic extract of Artemisia dracunculus L., as a novel anti-inflammatory agent. The ethanolic extract, termed PMI 5011, reduced IL-1β-mediated NF-κB activity. DMC2 retained this ability, indicating this compound as the likely source of anti-inflammatory activity within the overall PMI 5011 extract. We further …

Population and Public Health Science Faculty Publications

We estimated sibling resemblance in health-related physical fitness (PF) and examined how individual characteristics and shared natural environment accounted for sibling similarities. The sample comprised 656 sibling pairs and 102 triplets (6–15 years of age), from three geographical areas of Peru. PF components included morphological (waist circumference, sum of skinfolds), muscular (handgrip strength, standing long jump), and motor (shuttle-run). Body mass index (BMI) and somatic maturation were also assessed. In general, sibling intraclass correlations differed significantly across sib-ship types for waist circumference and handgrip strength but were the same for sum of skinfolds, standing long jump, and shuttle-run. Further, in …

Expression Of Arylamine N-Acetyltransferase 2 Activity In Immortalized Human Bronchial Epithelial Cells, James T.F. Wise, Raúl A. Salazar-González, Mariam R. Habil, Mark A. Doll, David W. Hein

Faculty Publications

Lung cancer is the leading cause of cancer deaths in the United States with high incidence in tobacco smokers. Arylamine N-acetyltransferase 2 (NAT2) is a xenobiotic enzyme that catalyzes both N- and O-acetylation of carcinogens present in tobacco smoke and contributes towards the genotoxicity of these carcinogens. NAT2 allelic variants result in slow, intermediate, and rapid acetylation phenotypes. A recent meta-analysis reported NAT2 non-rapid (slow and intermediate) phenotypes had a significantly increased risk of lung cancer. NAT2 activity in humans is thought to be restricted to liver and gastrointestinal tract, and no studies to our knowledge have reported the expression …

Thinking Inside The Box: The Future Of Young Children's Physical Activity And The Home Environment, Chelsea L. Kracht, Amanda E. Staiano

Population and Public Health Science Faculty Publications

Parrish et al.‘s (2021) investigation of caregiver perceptions of preschoolers' physical activity (PA) within the home environment posits important opportunities for public policy to consider space and available opportunities for PA for preschoolers. This study uncovered qualitative themes on preschoolers' PA in the home, referencing the use of indoor and outdoor spaces, adaptations within the home, interplay between space and caregiving, and variability in child's PA. This work sparks a discussion into the current understanding of the home environment for preschooler PA and future research directions. We propose three main areas to bring forward physical activity and public health research, …

Preventing Brand Activism From Backfiring: How The Use Of An Ingroup Model Can Limit The Negative Effects Of One-Time Csr History, Cole C. Dunnam

LSU Master's Theses

Brands are beginning to engage in corporate social advocacy (CSA) with social movements to form deeper connections with their audience, but not all are successful. This thesis asks why a brand’s target audience considers some CSA campaigns as more authentic than others. In Study I, I use Twitter data to conduct an exploratory analysis that applies existing research to two extreme CSA cases: Nike’s Emmy-winning “Dream Crazy” campaign starring Colin Kaepernick and Pepsi’s unsuccessful “Live for Now– Moments” campaign starring Kendall Jenner. Pepsi failed despite its history of corporate social responsibility (CSR) initiatives. I suggest that group identity theory impacts …

Public Safety Response For Persons With Serious Mental Illness: A Systematic Review Of Literature, Ashley Bailey

LSU Master's Theses

There are 13.1 million adults living with serious mental illness (SMI) in the United States. It is estimated that 356,000 people with SMI are incarcerated in the United States. Many advocates believe that police reform/alternatives to traditional policing could assist in lowering incarceration rates among persons with SMI, and improve outcomes for both the officer and the person with SMI during police contact.
