Flood Resilience Assessment Of New Orleans After Hurricane Katrina Based On Thermal And Vegetation Index Image Time Series, Yirui Deng

LSU Master's Theses

Resilience is a concept with increasing importance in modern risk management because of its role in reducing risks of unpreventable disasters. Previous resilience assessment studies often require extensive surveys of various social, economic, and psychological data or incorporate remote sensing data as one of the complicated physical and social parameters for assessment models. Limited data accessibility to such data due to funding, time, and labor intensity is a major challenge for their wider applications. Therefore, this study proposes the hypothesis that the overall resilience of an urban area to disturbances of natural disasters can be reflected through the time series …

String Out And Compressibility Effect On Pressure Rise In A Shut-In Well, Nicholas Henry

LSU Master's Theses

Gas kick migration experiments were performed in a small-scale well prototype model of annular geometry to analyze the behavior of gas kicks in highly non-Newtonian fluids. The objective was to isolate and estimate the effects system compressibility and bubble string out have on the pressure build up in a situation in which a gas kick rises through a noncirculating drilling mud in a vertical well.

The experiments consisted of 2 tests. The first test measured the apparent compressibility of the liquid phase of the experiment – that phase which simulated the drilling mud in a gas kick situation. The second …

Effects Of A Repeated Writing Intervention On Writing Fluency And Writing Quality, Katherine L. Moore

LSU Master's Theses

Writing is a fundamental skill that is essential for students’ academic success. In fact, students with writing difficulties are shown to have lower academic achievement and reduced likelihood of college acceptance (Graham & Perin, 2007). Writing fluency is a crucial component in the development of writing abilities, as it allows for the development of higher-order writing skills (Bloom, 1986, Binder, Haughton & Bateman, 2002). Limited research exists of interventions targeted specially for writing fluency; however, performance feedback procedures have been shown as effective (Hier & Eckert, 2016). Literature suggests the skills of reading and writing share similar processes of learning …

Examining The Role Of Job Resources As Moderators In The Relationship Between Job Stress, Job Satisfaction, And Quit Intention In Teachers, Leanna Becnel Cupit

LSU Doctoral Dissertations

Abstract

Teacher attrition is a major problem facing education today. Some literature reports as many as half of all teachers leave the profession within the first five years. The current study sought to examine the role of resources as moderators to the impacts of job stress and job satisfaction on quit intention in early career teachers. Drawing from conservation of resource theory, findings from this study show that high levels of job stress and low levels of job satisfaction are related to increased quit intention. However, results from this study showed no difference in the stress, satisfaction, and quit intention …

The study involved conducting qualitative interviews followed by collecting survey data to answer the following research questions: 1) What motivating factors lead informal AD caregivers to seek out information? How do their information needs change? Why do informal caregivers choose to utilize certain resources more than others? Is there a correlation between information seeking and resulting stress levels? Does health literacy moderate the association between …

The Rhetoric Of Sickle Cell Anemia, Raquel Mcfarland Robvais

LSU Doctoral Dissertations

My dissertation examines the rhetorical treatment of sickle cell anemia as synecdoche, representing a preoccupation with racialized discourses of disease and the affective registers manifested in public life. From its inception SCA has taken on cultural meanings to satisfy ideological arguments about the nature of black bodies.

It has been appropriated to create “categories of difference and belonging” (Schramm et al). I examine how SCA is gathered by rhetors to serve varying ideological purposes and cultural communities. It is utilized to invite different readings that conceptualize the black body as an object of scientific experimentation, as an agent for resistance …

Sensory Analysis For Determining The Influence Of Visual Stimuli Upon Eating Experiences, Pitchayapat Chonpracha

LSU Doctoral Dissertations

Consumers are currently more conscious about salt and sugar intake than they were in the past. Visual cues have been shown to impact consumers’ cognitive and their taste perceptions. Current research information about visual cues enhancing human’s tastes expectation of saltiness and sweetness is limited. The sophisticated sensory analysis for products containing a reduced amount of salt and sugar is undoubtedly time–consuming and costly if the sensory experiment is designed with many samples. Therefore, the following three studies were achieved: I) an examination of how intrinsic and extrinsic visual cues affect the overall consumer eating experiences; II) a comparison of …

Novel Media: Global Contemporary Fiction In The Digital Age, Mary Catherine Pappalardo

LSU Doctoral Dissertations

Novel Media argues that contemporary literature—particularly the novel form—is best decoded in terms of the new media forms that have proliferated since the dawn of the internet. Perhaps no other development has so dramatically shaped contemporary life than the ubiquity of the internet, internet-capable devices, and the myriad social networks that have blossomed within. Fiction is no different; the social media forms that dominate our lives online have also, I argue, rewired the way novels work in the twenty-first century. As such, a new reading practice is required that attends to these seismic changes to the novelistic terrain. The project …

Microscale Metal Forming: Mesoscopic Size Effect, Extrusion And Molding, Bin Zhang

LSU Doctoral Dissertations

The continuing trend of metallic device and product miniaturization has motivated studies on microscale metal forming technologies. A better understanding of materials’ mechanical response and deformation behavior is of importance for the design and operation of micro metal forming processes. In this dissertation, uniaxial compression testing was conducted on Al ring and pillar specimens with characteristic dimensions at meso to micro scales. The experimental data reveal inadequacies of the existing surface layer model and provides a baseline for delineating deformation mechanisms in micro metal forming operations. Microscale reverse extrusion experiment was carried out on Cu and Al rod specimens with …

Disaster Vulnerability And Social Capitals In The Gulf Coast And Flint, Michigan, Vanessa Parks

LSU Doctoral Dissertations

In this dissertation, I explore the migration intentions, self-rated physical and mental health, and alcohol use of people living in regions facing environmental stressors. In my first chapter, I examine factors that predict willingness to move away from southeast Louisiana, a region threatened by land loss, hurricanes, and environmental pollution. Specifically, I assess the relationships risk perceptions, place attachment, and fishing employment have with willingness to move. I find that risk perceptions are positively related to willingness to move and that place attachment and fishing employment are negatively related to willingness to move. In my second chapter, I show the …

Finding Rough America, Eric Kennedy

LSU Doctoral Dissertations

Finding Rough America seeks to establish and examine the components of a body of texts, both in prose and film, that I call Rough America. I argue that this corpus works to broaden the cultural understanding of literature and film about the lives of American lower classes. To do so, I adopt and adapt Guy Standing’s conception of the “precariat class,” an economic classification used to identify the widespread precariousness among what was once the middle- and working-classes. After establishing Rough America as following in the tradition of American literary naturalism, I ground the study of the corpus’s primary thematic …

Effective Geometric Modeling For Scientific Computing And Forensic Reconstruction, Celong Liu

LSU Doctoral Dissertations

Geometric modeling is a fundamental and critical problem for many computer graphic and computer vision problems. We usually want to build a parameterization which establishes a low-distortion one-to-one map between geometric data and canonical parametric domain, and it is a fundamental tool to support many visual data processing tasks such as mesh generation, finite element simulations, visual analytics, geometric reconstruction, etc. In this dissertation, I studied two problems. The first is to construct low- distortion canonical (polycube) parameterization of large-scale geometric regions, with which high-quality semi-structured quad meshes can be generated and used to facilitate more efficient scientific computing. The …

Development Of Sheath Blight-Resistant Breeding Lines For Southern U.S. Environments And Morphological And Genetic Survey Of Giant Salvinia Populations In Louisiana And Texas, Dominique Clark Galam

LSU Doctoral Dissertations

The southern US environment is a very conducive environment for agriculture and fisheries. Rice farming, shrimping and water related activities help drive the local economy. However, there are several factors that impede the success of these activities. Sheath blight (SB) disease caused by Rhizoctonia solani is one of the major biotic constraints to high grain yield and quality for most commercial U.S. rice varieties. Although different breeding lines with high levels of "partial resistance" have been developed none has been used directly as a commercial variety. The first research objective of this research was to identify and develop advanced breeding …

Three Essays On Irrigation Water Management In Louisiana Crop Production, Tej Kumar Gautam

Competition for water resources among agricultural, municipal, and industrial sectors is increasing even in a traditionally water rich state like Louisiana. Irrigation water management is likely to be a critical issue in Louisiana in the near future. We conducted state-wide farm surveys to collect information regarding irrigation practices and concerns from Louisiana farmers during the crop years 2015 and 2016.

We analyzed three different issues associated with irrigation water management in Louisiana crop production. These analyses are presented in the form of three different essays. The first essay identifies the determinants of irrigation technology adoption and crop acreage allocation by …

The Child Ethnographer In The Field: Examples From English, Spanish, And French Caribbean Literature, Emily Ann O'Dell

LSU Doctoral Dissertations

In this dissertation I consider the child to be an ethnographer in works of fiction and autofiction from the Caribbean islands. Through their liminality as culturally and developmentally betwixt or between, their cultural malleability, their linguistic fluidity, and their curiosity, the child becomes a "native" ethnographer who is capable of translating the culture (both linguistically and culturally) for the reader in order to establish understandings of Caribbean cultures. This is accomplished through the creation of hybridized or creolized texts that have many of the same characteristics as postmodern ethnographies.

In the English Caribbean Xuela provides an ethnographic perspective of Dominican …

Multiple Voices In The Poetry Of Transculturation: Reading Contemporary Ex-Phonic Poetry Through Muwaššah: Ryoko Sekiguchi, Etel Adnan, And Suheir Hammad, Thana Al-Shakhs

LSU Doctoral Dissertations

This research is a comparative study that compares two types of multicultural poetry: contemporary poetry written by non-native speakers and the Andalusian medieval genre of muwaššah. In spite of the cultural and temporal gap between the two periods, the poets apply similar strategies to represent multicultural voices, for example integrating foreign expressions. I argue that multicultural poetics break the rules of classical writing and use oral expressions that are more flexible to include different languages and cultural references. This study focuses on oral techniques that offer an appropriate style to express multiplicity.

This thesis is divided into four chapters. …

The Garbage That We Eat: Metabolizing Food-Waste In New Orleans, Louisiana, Kelly L. Haggerty

LSU Master's Theses

The 2017 Climate Action for a Resilient New Orleans report strives to divert 50 percent of waste by 2030. In the same year, waste companies had only managed to divert 5 percent of the total annual waste in Orleans Parish. Nearly a decade away from 2030, city officials have not even tested or implemented strategies to reach this goal. While city officials scramble to launch pilot projects, community and grassroots organizations center around recovering and transforming garbage and food waste. Using interviews and surveys with food-waste organizers from May to August 2018, this paper reveals that managing food-waste on a …

Over the past years, shale gas has turned into one of the most significant sources of energy in the United States. Technological advancements have provided the energy industry with the necessary tools to allow the economic exploitation of an enormous volume of natural gas trapped in shale formations. This has boosted the domestic gas production and generated a boom in other sectors of the economy in the country. However, major challenges are involved in the development of shale gas resources. A drastic decline of wells’ productivity, the costs involved in the gas production and distribution facets, and the volatile behavior …

Deltaic Wetland Dynamics From Seasonal To Centennial Scales, Giancarlo A. Restreppo

LSU Doctoral Dissertations

The lower plain of the Mississippi River Delta contains approximately five coastal sedimentary basins that are topographically defined, and one shelf-crossing depocenter (the Birds Foot Delta). These depositional systems receive varying quantities of sediment from fluvial and marine sources and have rates of coastal land loss that are roughly inversely proportional to fluvial sediment supply. To combat land loss along these regions, Louisiana has launched a historic campaign to sustain and regrow coastal lands using, in part, river sediment diversions. Fine sediments constitute the majority of sediment load in the Mississippi River, but are under-studied with respect to dispersal processes, …

An Archive Of Pain: In Queer Suicide's Cultural Wake, Evan Schares

LSU Doctoral Dissertations

In this dissertation, I argue that queer death is a chief site of political struggle over gender, race, and sexuality in contemporary culture. I consider myriad archives in the aftermath of three queer suicides, an aggregate of discourses I call cultural wakes, to examine how white affective investments circulate around the forces of racism, sexism, and citizenship. I place in situ the trauma of queer pain and loss against the global backdrop of public emotionality.

From Rationality To Relationality: Teacher-Student Relationship As Unknowing, Shaofei Han

LSU Doctoral Dissertations

This dissertation reimagines the teacher-student relationship through a philosophical approach that draws on Laozi, Karen Barad, Deleuze & Guattari, and Emmanuel Levinas. The teacher-student relationship is normally considered a relationship of the knower (teacher) and the unknower (student) based on the modern western tradition of episteme. This dissertation interrogates the modern binary of the teacher/student, subject/object relationship by bringing ontology and ethics into educational discourse. The problematic practices of modern schooling include the reduction of teaching to knowledge transmission, and the rigid dichotomy of a subject/object relation between teacher and student. Following a Taoist Way of philosophical thinking, this work …

A Pedagogical And Performance Approach To A Selection Of Piano Solo Pieces Written By Chen Yi And Zhou Long, Weiying Tang

LSU Doctoral Dissertations

This dissertation will focus on the performance and pedagogical features of six piano solos composed by Chen Yi and Zhou Long. Both composers are Chinese-American who earned their Bachelor degrees in music from the Central Conservatory in Beijing, and came to United States in 1985-1986 to pursue doctoral studies in composition at Columbia University. Because of the composers’ personal experience, they were not only familiar with Chinese regional folk elements, but also trained in the Western classical music tradition. Their works tend to blend and expand both Chinese and Western cultural traditions, musical ideas and techniques.

LSU Doctoral Dissertations

John Corigliano is one of the most famous American composers of modern times having gained global recognition over the course of his career. The focus of this dissertation is on one of his earlier works, the Sonata for Violin and Piano. This sonata is the first of his compositions to have gained international attention. In the Sonata for Violin and Piano, Corigliano uses traditional music elements that are accessible to the audience. Although it is based on the traditional composition, Corigliano uses ambiguous tonality, polytonality, complicated rhythm, and polyrhythm throughout the piece. These factors cause several technical issues which occur …

Population Dynamics And Demographics Of Spotted Seatrout, Cynoscion Nebulosus, Through Spatial Analysis: Towards An Integrative Management Approach, Ashley Melancon Baer

LSU Doctoral Dissertations

Spotted seatrout (Cynoscion nebulosus) is one of the most highly prized sportfish along the Gulf of Mexico coast, particularly in Louisiana. Although spotted seatrout are considered to be well managed and sustainably fished according to the state’s most recent stock assessment, the spatial ecology of this species is largely understudied in Louisiana waters. Acoustic telemetry is an innovative technology that is commonly used to assess the movements and behavior of aquatic species, and can be used as a tool to address the paucity of information on the spatial dynamics of spotted seatrout. The focus of this study was …

Understanding The Social Relationships Of Youth With Callous-Unemotional Traits Using Peer Nominations, Tatiana M. Matlasz
