Des Rois Anglais Qui Parlent Français : Une Etude Sur La Situation Linguistique En Angleterre Après La Conquête Normande, Trent Dunkin

Tête à Tête: Journal of Francophone Studies

Prior to 1066, England was ruled by the Germanic speaking Anglo-Saxons. However, after the defeat of Harold II at the Battle of Hastings, William the Conqueror became King of England, ushering in a lengthy era in which English monarchs were primarily francophone. This article explores the linguistic situation in England before, during, and after the Norman Conquest of 1066. Specifically, this article looks at the Anglo-Norman dialect as a distinct Langue d’Oïl, focusing primarily on its phonetics, syntax, and orthography, using examples found in Laüstic and Chèvrefeuille, two lais written by Marie de France in the late 12 …

Euphemism In Ai Discourse As Colonial Harm & Effect: Learnings From Subaltern Puerto Rico, Jacqueline Oquendo

LSU Doctoral Dissertations

Through three integrated studies, this dissertation explores complex human-AI interactions by comparing the perceptions of two groups of U.S. citizens: subaltern Puerto Ricans and stateside Americans’ interactions with ChatGPT. This corpus-assisted Critical Discourse Analysis or CLCDA, triangulated with 1:1 semi-structured interviews, validates scholars’ concerns about the biases inherent in generative AI. Contributing to those concerns, this dissertation reveals that ChatGPT deploys discourse strategies that, when executed, facilitate digital colonialism. Euphemistic language is prominent among its discourse strategies, replacing controversial words, phrases, and topics with more palatable ones. When prompted on events of historical significance, I find that ChatGPT’s discourse obscures …

Online Eye Tracking For Aphasia: A Feasibility Study Comparing Web And Lab Tracking And Implications For Clinical Use, Willem S. Van Boxtel, Michael Linge, Rylee Manning, Lily N. Haven, Jiyeon Lee

Faculty Publications

Background & Aims: Studies using eye-tracking methodology have made important contributions to the study of language disorders such as aphasia. Nevertheless, in clinical groups especially, eye-tracking studies often include small sample sizes, limiting the generalizability of reported findings. Online, webcam-based tracking offers a potential solution to this issue, but web-based tracking has not been compared with in-lab tracking in past studies and has never been attempted in groups with language impairments. Materials & Methods: Patients with post-stroke aphasia (n = 16) and age-matched controls (n = 16) completed identical sentence-picture matching tasks in the lab (using an EyeLink system) and …

Validation Of The Quick Mild Cognitive Impairment Screen In An American Sample Of Patients With Mild Cognitive Impairment And Mild Dementia, Dariella A. Fernandez, Suzanne Schmitz, Heather Foil, Robert Brouillette, Jeffrey N. Keller, Robin C. Hilsabeck

Clinical Research Faculty Publications

Objective: Early detection of cognitive impairment is critical for patient outcomes, yet cognitive impairment is under identified in primary care settings largely due to time constraints. The Quick Mild Cognitive Impairment (Qmci) screen was developed to address the need for a short cognitive screening instrument (< 5 min) that is sensitive to early cognitive change but has not been validated in the United States (US). The objective of this study was to examine the classification accuracy of the Qmci in participants from two memory specialty (e.g., secondary outpatient) clinics in the US. Methods: Participants were 152 older adults: 87 participants were cognitively normal (CN), 48 were diagnosed with mild cognitive impairment (MCI) and 17 were diagnosed with mild dementia (DEM). Classification accuracy of the Qmci and Mini Mental State Examination (MMSE) were compared in participants with and without cognitive impairment. Results: The Qmci demonstrated higher classification accuracy in differentiating CN from cognitively impaired participants (i.e., MCI and DEM) (AUC = 0.82) than the MMSE (AUC = 0.77). The optimal cut-off score for the Qmci was < 67, which achieved a sensitivity of 79% and specificity of 80%. The optimal MMSE cut-off score was < 27, which achieved a sensitivity of 97% and specificity of 43%. Conclusions: The Qmci is a valid cognitive screening instrument for detecting early stages of cognitive impairment in memory clinic samples in the US. Its short administration time and increased specificity for detecting MCI make it an attractive option for use in primary care settings. Further validation of the Qmci is needed, specifically within primary care settings.

Do #Blm At The Plantation: A Study Of Plantation Tourism After The Racial Reckoning Of 2020, Denetria N. Lee

LSU Master's Theses

Following the murder of George Floyd at the hands of Minneapolis police officer Derek Chauvin, the widespread public protest of racial injustice created a groundswell that prompted corporate and media responses, so much so that by the end of the summer of 2020, it seemed as if "Black Lives Mattered" everywhere and to everyone. Public response incentivized subsequent corporate response in financial pledges and other commitments to racial justice initiatives until 2020, which became known as the year that America confronted racism or the racial reckoning of 2020. While the public demanded acknowledgment of the many forms of contemporary racial …

Redefining The Art Songs Of Maude Valérie White, Sarah C. Rees

LSU Doctoral Dissertations

Maude Valérie White (1866-1937) was an English composer during the Victorian Era. Her main output was in the genre of art song, of which she wrote more than two hundred during her life. Her music was very popular at the height of her career around 1880-1890, but fell out of favor with the general public in line with the general reaction against Victorian art and ideals. This written document focuses on the life of Maude Valérie White contextualized within the ideals of Victorian womanhood. It will explore the development of her musical style through eight song analyses: The Devout Lover, …

Exploring The Efficacy Of Transcutaneous Auricular Vagal Nerve Stimulation On Post-Stroke Aphasia: A Single-Subject Design Study, Aswathy Anakkathil Pradeep

LSU Doctoral Dissertations

Background: Anomia or word-retrieval difficulty is a common long-term language impairment for individuals with post-stroke aphasia. Several behavioral interventions like semantic feature analysis (SFA) have shown positive results in naming outcomes, but continue to face difficulty in generalizing the treatment effects to untreated items. With recent advancements in technology, researchers are developing newer neuromodulation devices that aim at promoting neuroplasticity and neural reorganization in post-stroke individuals. Transcutaneous auricular vagal nerve stimulation (taVNS) is a relatively new technology that aims at stimulating the auricular branch of the vagal nerve to promote neuroplasticity. Studies have shown taVNS to potentially facilitate positive improvements …

Intensification Strategies Of Southern Arizona Bilinguals, Sadie E. Seilhan

LSU Master's Theses

The present thesis explores the intensification strategies employed by bilingual Spanish-English speakers in Southern Arizona, focusing on six distinct devices: lexical, phrasal, repetition, reformulation, hyperbole, and code-switching. While previous research has largely centered on adverbial and lexical intensifiers in monolingual contexts, this study broadens the scope by examining how bilingual speakers leverage their unique linguistic repertoire to amplify their speech. Using a sociopragmatic framework, the analysis reveals a marked preference for lexical intensification, which accounts for more than half of the recorded instances, with phrasal intensification and repetition following closely. Despite its lower frequency, code-switching stands out as a particularly …

Stress On The Brain: An Investigation Into The Impact Of Stress On Learning, Memory, And Metamemory Processes, Felicia M. Chaisson

LSU Doctoral Dissertations

While acute anxiety or stress has been shown to enhance certain cognitive functions, such as memory for emotionally salient stimuli, its effects on memory for emotionally neutral information remain ambiguous. Successful memory encoding and retrieval often involve control processes—both self-initiated and directed—that dictate organization during learning. Previous research indicates that these processes facilitate the contextual binding and organization of information. However, multi-domain evidence suggests that stress during encoding may be disrupted due to changes in neural mechanisms at play. This dissertation explores how stress impairs cognitive control, identifies potential underlying neural correlates, and examines broader metacognitive influences. Chapter 1 begins …

Examination Of Musical Sophistication And Working Memory Correlates In High School Students, Abby South

LSU Doctoral Dissertations

Abstract

The purpose of this study was to examine the relationship between musical engagement and cognitive ability in high school students. While musicians’ brains have long been of interest to those who study experience-dependent neuroplasticity, a lack of adolescent data grossly limits our understanding of the relationship between music training and observed neuroplastic changes in the brain. Advances in psychometric testing and brain imaging reveal relationships among musical expertise, changes in brain function, structure, and connectivity, and enhanced cognitive ability, but categorical groupings of dichotomously defined musicians and non-musicians prevent nuanced understanding of these complex relationships. In this study, 83 …

We review the functioning and sustainability of coastal marshes and mangroves. Urbanized humans have a 7,000-year-old enduring relationship to coastal wetlands. Wetlands include marshes, salt flats, and saline and freshwater forests. Coastal wetlands occur in all climate zones but are most abundant in deltas. Mangroves are tropical, whereas marshes occur from tropical to boreal areas. Quantification of coastal wetland areas has advanced in recent years but is still insufficiently accurate. Climate change and sea-level rise are predicted to lead to significant wetland losses and other impacts on coastal wetlands and the humans associated with them. Landward migration and coastal retreat …

A Coarse-Grained Molecular Dynamics Study Of Gas Hydrate Formation And Dissociation, Meisam Adibifard

LSU Doctoral Dissertations

The study of gas hydrates has increased significantly over the last two decades because of their potential application in energy storage, production and transportation, water desalination, refrigeration, gas separation, etc. There is a significant interest in commercially developing natural gas hydrates because the energy content of methane hydrate reservoirs (MHRs) is at least twice that of all conventional fossil fuels combined. Additionally, due to the higher storage capacity of hydrates, it is proposed to sequester CO₂ in the form of CO₂ hydrate, thereby reducing the amount of greenhouse gases. Hence, hydrates offer a dual solution to two of …

Because of the first observations in the 1900s of the oligotrophic and eutrophic states of lakes, researchers have been interested in the process that makes lakes become turbid because of high phytoplankton biomass. Definitions of eutrophication have multiplied and diversified since the mid-20th century, more than for any other ecological process. Reasons for the high number of definitions might be that the former ones did not sufficiently describe their causes and/or consequences. Global change is bringing eutrophication more into the spotlight than ever, highlighting the need to find consensus on a common definition, or at least to explain and clarify …
