Maternal Fatty Acid And Inflammatory Status During Pregnancy Are Related To Infant Heart Rate And Heart Rate Variability, Merritt Leanne Drewery Jan 2017

Maternal Fatty Acid And Inflammatory Status During Pregnancy Are Related To Infant Heart Rate And Heart Rate Variability, Merritt Leanne Drewery

LSU Doctoral Dissertations

Early life heart rate (HR) and heart rate variability (HRV) reflect autonomic maturation. Intervention with n-3 long chain polyunsaturated fatty acids (LCPUFAs) during pregnancy favorably affects fetal HR and HRV; similar observations have been reported with infant n-3 LCPUFA intake. Infant HR and HRV have not been assessed in relation to maternal fatty acid status during pregnancy. Further, exposure to intrauterine inflammation may underlie these observations, although this hypothesis has not been tested. The aim of this observational study was to explore associations between maternal fatty acid and inflammatory status during pregnancy and infant HR and HRV. Simple linear and …


Analysis And Optimization Of Scientific Applications Through Set And Relation Abstractions, M. Tohid (Rastegar Tohid, Mohammed) Jan 2017

Analysis And Optimization Of Scientific Applications Through Set And Relation Abstractions, M. Tohid (Rastegar Tohid, Mohammed)

LSU Doctoral Dissertations

Writing high performance code has steadily become more challenging since the design of computing systems has moved toward parallel processors in forms of multi and many-core architectures. This trend has resulted in exceedingly more heterogeneous architectures and programming models. Moreover, the prevalence of distributed systems, especially in fields relying on supercomputers, has caused the programming of such diverse environment more difficulties. To mitigate such challenges, an assortment of tools and programming models have been introduced in the past decade or so. Some efforts focused on the characteristics of the code, such as polyhedral compilers (e.g. Pluto, PPCG, etc.) while others …

Local Embeddedness Matters: A Study Of Hip-Hop Artists' Interaction With Their Local Community, Castel Vette Sweet

LSU Doctoral Dissertations

This dissertation study is an exploration of hip hop and rap artists’ embeddedness in local communities, and their interpretation of the connectedness between their work and their communities. I explore the influence of place and space in the identity development of artists, and how artist use those identities to guide their interactions with their local community. I also investigate the significance of artists’ interactions and relationship in the cultivation of social and cultural capital. In contrast to previous scholarship emphasising the negative influence rap and hip-hop artists have on their communities, I utilize in-depth interviews with artists to examine the …


Distributed Kalman Filters Over Wireless Sensor Networks: Data Fusion, Consensus, And Time-Varying Topologies, Jianming Zhou Jan 2017

Distributed Kalman Filters Over Wireless Sensor Networks: Data Fusion, Consensus, And Time-Varying Topologies, Jianming Zhou

LSU Doctoral Dissertations

Kalman filtering is a widely used recursive algorithm for optimal state estimation of linear stochastic dynamic systems. The recent advances of wireless sensor networks (WSNs) provide the technology to monitor and control physical processes with a high degree of temporal and spatial granularity. Several important problems concerning Kalman filtering over WSNs are addressed in this dissertation. First we study data fusion Kalman filtering for discrete-time linear time-invariant (LTI) systems over WSNs, assuming the existence of a data fusion center that receives observations from distributed sensor nodes and estimates the state of the target system in the presence of data packet …


Brazilian Surface And Upper-Level Wind Characteristics Based On Ground And Model Observations From 1980–2014, Joshua M. Gilliland Jan 2017

Brazilian Surface And Upper-Level Wind Characteristics Based On Ground And Model Observations From 1980–2014, Joshua M. Gilliland

LSU Doctoral Dissertations

The examination of temporal changes in surface winds has been analyzed by scientists for a variety of physical, biological, climatological, and socioeconomic reasons. This research uses surface and upper-level wind data from historical in-situ and climate models to examine the geographical and climatological characteristics of wind across Brazil during 1980–2014. Overall linear and quantile regression shows that surface wind speed trends are changing regionally across Brazil. Wind speeds across northeastern Brazil are increasing, while a decreasing trend is documented for interior and southeastern Brazil. The spatial and temporal trends found are possibly related to alterations in the physical landscape (urbanization …

Data for this study was obtained from institutional sources and consisted of 9-16 detail high school record, admissions, financial aid, scholarship and enrolled student information. Univariate and Multi-variate statistical analyses …


Moduli Spaces Of Flat Gsp-Bundles, Neal David Livesay Jan 2017

Moduli Spaces Of Flat Gsp-Bundles, Neal David Livesay

LSU Doctoral Dissertations

A classical problem in the theory of differential equations is the classification of first-order singular differential operators up to gauge equivalence. A related algebro-geometric problem involves the construction of moduli spaces of meromorphic connections. In 2001, P. Boalch constructed well-behaved moduli spaces in the case that each of the singularities are diagonalizable. In a recent series of papers, C. Bremer and D. Sage developed a new approach to the study of the local behavior of meromorphic connections using a geometric variant of fundamental strata, a tool originally introduced by C. Bushnell for the study of p-adic representation theory. Not only …


Revisions To Rainfall Intensity Algorithms In Przm5.0 To Improve Estimates Of Off-Field Runoff, Eroded Sediment And Pesticide Mass, Tammara Levey Estes Jan 2017

Revisions To Rainfall Intensity Algorithms In Przm5.0 To Improve Estimates Of Off-Field Runoff, Eroded Sediment And Pesticide Mass, Tammara Levey Estes

LSU Doctoral Dissertations

The Environmental Protection Agency (EPA) model Pesticide Root Zone Model, version 5.0 (PRZM5.0) is used to estimate off-field loadings of pesticide concentrations in runoff and eroded sediment. Climate change has resulted in an increase in rainfall intensity patterns for much of the United States. This change impacts off-field runoff and eroded sediment as well as off-field pesticide loads from agricultural fields. Thus, the PRZM5.0 EPA “lookup” table for runoff curve numbers and the internal algorithm for eroded sediment estimation have become outdated since both temporal and geographical conditions have changed. This research presents (1) a revised method for estimating runoff …

Exact Numerical Study Of Disordered Systems, Conrad Wilson Moore

LSU Doctoral Dissertations

This thesis presents work on the development of new techniques to study the problem of localization in various models of disordered systems with the goal of being able to extend these model calculations to real materials where these various mechanisms of disorder can all be present. I consider the Anderson Model with diagonal, off-diagonal disorder, multiple bands and superconductivity is included at the level of a Bogoliubov - De Gennes mean field (superconductivity is considered by adding the symmetries of the Bogoliubov - De Gennes Hamiltonian on top of the disordered lattice Hamiltonian). The localization of electrons is studied with …


Osteogenic Potential Of Poly (L-Lactic Acid) Scaffolds Prepared By Thermally Controlled Methods On Human Adipose Derived Stem Cells, Harish Chinnasami Shanmugam Jan 2017

Osteogenic Potential Of Poly (L-Lactic Acid) Scaffolds Prepared By Thermally Controlled Methods On Human Adipose Derived Stem Cells, Harish Chinnasami Shanmugam

LSU Doctoral Dissertations

Thermally Induced Phase Separation (TIPS) method was used to make porous three-dimensional PLLA scaffolds. The effect of imposed thermal profile during freezing of the PLLA in dioxane solution on the scaffold was characterized by their micro-structure, porosity (%), pore-sizes distribution and mechanical strength. The porosity (%) decreased considerably with increasing concentrations of PLLA in the solution, while a decreasing trend was observed with increasing cooling rates. The mechanical strength increases with increase in PLLA concentration and also with increase in the cooling rate for both types of solvents. Therefore, mechanical strength was increased by higher cooling rates while the porosity …


Private Vs. Public: Lesbian, Gay, Bisexual, And Transgender Student Experiences And The Influence Of Anti-Discrimination Policies With Respect To Religion, Shalonda Michelle Skidmore Jan 2017

Private Vs. Public: Lesbian, Gay, Bisexual, And Transgender Student Experiences And The Influence Of Anti-Discrimination Policies With Respect To Religion, Shalonda Michelle Skidmore

LSU Doctoral Dissertations

For a vast majority of Americans, religion is an integral part of life. In fact, 10:30am on Sundays is considered the most holy time in the United States as most persons have just left, are currently attending, or are on their way to their various places of worship. Believing in organized religion comes with challenges, as religion has often been the basis and justification for discriminatory practices. These challenges can cause emotional tension, especially to those who identify with teachings that religions have traditionally condemned. This document sought to determine if religion matters to lesbian, gay, bisexual, and transgender (LGBT) …


Evolutionary Interactions Of Feather Molt In Birds, Ryan Scott Terrill Jan 2017

Evolutionary Interactions Of Feather Molt In Birds, Ryan Scott Terrill

LSU Doctoral Dissertations

The evolution of feathers was a key innovation for birds. The many functions that feathers provide have allowed birds to diversify into myriad habitats and styles of life. However, feathers are lightweight and break down, and must be replaced regularly in a process known as molt. The patterns and timing with which birds molt varies within and between species, and these different strategies are likely a product of the different ways birds use their feathers and the uneven distribution of resources available for molt in time and space. So far, no studies have attempted to place these strategies into an …

The influence of Quaternary climate variation on sediment generation, storage, and transport in two mountainous Asian river basin was examined in the largest tributary to the upper Indus River in the Himalayan rain shadow, the Zanskar River basin (~15,000 km2), and the smaller, subtropical Song Gianh basin (<3,500 km2) of central Vietnam. Spatial patterns of erosion in the Zanskar River Basin were established to quantify the dominant controls on Quaternary sedimentation in the Himalayan rain shadow on the edge of the Tibetan Plateau. Glacial erosion and precipitation along the High Himalaya together dominate sediment production and transport …


Empirically Tuning Hpc Kernels With Ifko, Md Majedul Haque Sujon Jan 2017

Empirically Tuning Hpc Kernels With Ifko, Md Majedul Haque Sujon

LSU Doctoral Dissertations

iFKO (iterative Floating point Kernel Optimizer) is an open-source iterative empirical compilation framework which can be used to tune high performance computing (HPC) kernels. The goal of our research is to advance iterative empirical compilation to the degree that the performance it can achieve is comparable to that delivered by painstaking hand tuning in assembly. This will allow many HPC researchers to spend precious development time on higher level aspects of tuning such as parallelization, as well as enabling computational scientists to develop new algorithms that demand new high performance kernels. At present, algorithms that cannot use hand-tuned performance libraries …


Application Of Grating-Based Interferometry To Additive Manufacturing, Lithium-Ion Batteries, And Crystals, Adam Joseph Brooks Jan 2017

Application Of Grating-Based Interferometry To Additive Manufacturing, Lithium-Ion Batteries, And Crystals, Adam Joseph Brooks

LSU Doctoral Dissertations

X-ray and neutron imaging are convenient ways to non-destructively observe novel materials. X-rays provide advantages of low cost and high brilliance while neutrons show bulk and isotopic sensitivity. Imaging provides a way for observing chemical and physical properties of materials without the need for destruction. The way of the imaging future is utilizing imaging with grating-based interferometry. In comparison to traditional radiography and tomography, by using absorption and phase gratings in the beam path, the absorption, phase, and scattering of a sample can be detected. In essence, three image datasets can be obtained in one experiment, saving substantially on costs …


Differential Effects Of Gratitude And Positive Peer Reporting Interventions On Student Subjective Wellbeing, Classroom Behavior, And School Connectedness, Rachel Marie Olinger Steeves Jan 2017

Differential Effects Of Gratitude And Positive Peer Reporting Interventions On Student Subjective Wellbeing, Classroom Behavior, And School Connectedness, Rachel Marie Olinger Steeves

LSU Doctoral Dissertations

Recent research and development in the ever-growing area of systems-level change in schools, including positive behavior interventions and supports (PBIS), school climate, and social-emotional learning (SEL), has stressed the importance in fostering positive outcomes for students. The additional focus on encouraging and promoting positive school-based relationships and cultivating individual student strengths has shown promising outcomes, including higher academic achievement, lower levels of problem behavior, and a greater sense of belonging in schools. However, in some disadvantaged and high-needs school districts, implementing systemic approaches or obtaining the personnel to implement individualized student services can prove exceedingly difficult, namely due to limited …

Disease, Bread, Efficiency: Rhetorics Of Victorian Education Reform, Vicki Jean Davis Jan 2017

Disease, Bread, Efficiency: Rhetorics Of Victorian Education Reform, Vicki Jean Davis

LSU Doctoral Dissertations

Disease, Bread, Efficiency: Rhetorics of Victorian Education Reform arose from my observation that, historically speaking, Anglo-American schools have always been “in crisis.” I argue that the crisis of the “failing school” is a rhetorical problem rather than an economic problem as most scholarship suggests. Much like the cultural myth of “the One True Love,” education reform debates tend to position the school as an institution that can rescue the nation from all perceived social ills. Not only is this unrealistic, the patterns of language are inconsistent as ideas about the purpose of school are translated into policy. This causes further …

Chapter 2 mainly focuses on the synthesis and characterization …


The Influence Of Social Support And Mental Illness On Punishment For Rule Violations Among Male Prisoners, Missy T. Malone Jan 2017

The Influence Of Social Support And Mental Illness On Punishment For Rule Violations Among Male Prisoners, Missy T. Malone

LSU Doctoral Dissertations

Mental illness among prisoners is higher than the general population (James & Glaze, 2006). The purpose of this exploratory-descriptive study was to investigate the social support and mental health factors that best predict punishment severity for institutional rule violations among prisoners. I conducted a secondary data analysis on 2004 Survey of Inmates in State Correctional Facilities data collected by the U.S. Census Bureau for the Bureau of Justice Statistics. The survey participants in this study consisted of a sample of 11,569 male prisoners. Bivariate analyses of interrelationships were conducted to assess whether significant relationships exist between the severity of punishment …


Ex-Companions Of Supernovae Progenitors, Zhichao Xue Jan 2017

Ex-Companions Of Supernovae Progenitors, Zhichao Xue

LSU Doctoral Dissertations

Supernovae (SNe) are titanic explosions that end the life of stars. Fast expanding ejecta can create brightness that is comparable to the entire luminosity of the host galaxy for weeks. Eventually, the ejecta run into the ambient medium, creating the so-called supernova remnant (SNR) that fades away in ~ 10,000 years. SNe come from two completely different mechanisms. The Type Ia SNe (SNIa) are powered by thermonuclear runaway when a white dwarf (WD) in a binary system accretes enough mass from a companion star. The Core Collapse supernovae (CCSNe) are massive stars that run out of fuel at the end …


Asymptotic Formulae For Restricted Unimodal Sequences, Richard Alexander Frnka Jan 2017

Asymptotic Formulae For Restricted Unimodal Sequences, Richard Alexander Frnka

LSU Doctoral Dissertations

Additive enumeration problems, such as counting the number of integer partitions, lie at the intersection of various branches of mathematics including combinatorics, number theory, and analysis. Extending partitions to integer unimodal sequences has also yielded interesting combinatorial results and asymptotic formulae, which form the subject of this thesis. Much like the important work of Hardy and Ramanujan proving the asymptotic formula for the partition function, Auluck and Wright gave similar formulas for unimodal sequences. Following the circle method of Wright, we provide the asymptotic expansion for unimodal sequences with odd parts. This is then generalized to a two-parameter family of …


Condition Of Birds In Amazonian Rainforest Fragments And Second-Growth Forests, Angelica Maria Hernandez Palma Jan 2017

Condition Of Birds In Amazonian Rainforest Fragments And Second-Growth Forests, Angelica Maria Hernandez Palma

LSU Doctoral Dissertations

Deforestation modifies otherwise intact expanses of forest into small, isolated fragments. In addition to fragmentation, deforestation also creates abrupt forest edges and large areas of regenerating vegetation where land is abandoned after clearing. Understanding how changes in the landscape affect the physical condition of birds is crucial for managing populations in human-modified landscapes. Here I use the biomarkers feather growth rate and feather quality (ptilochronology), fluctuating asymmetry (FA), and stress hormones from feathers (CORT), to estimate the physical condition of Amazonian understory birds living in forest fragments, second-growth forests, and continuous forests. Feather CORT revealed how fragmentation disrupts interspecific interactions; …

"In The School, Not Of The School": Co-Performing Critical Literacies With English Amped, Anna Catherine West

LSU Doctoral Dissertations

The purpose of this study was to explore the possibilities and limitations of “amplifying” critical literacy practices within an urban high school English and creative writing class. This action research project defamiliarized English education and created conditions for participants to imagine and perform alternative possibilities by bringing together critical research, community involvement, creative writing and performance in an extended class with high school, university, and community-based collaborators. Participants were high school juniors, partnering teachers, university-based student teachers, and community members who collaborated to form the English Amped program in the 2014-2015 academic year. Ethnographic methods were used to collect data …


The White Bicycle: Performance, Installation Art, And Activism In Ghost Bike Memorials, Nicole Marie Costantini Jan 2017

The White Bicycle: Performance, Installation Art, And Activism In Ghost Bike Memorials, Nicole Marie Costantini

LSU Doctoral Dissertations

In this project I examine the performative nature of the ghost bike memorial. Ghost bikes, flat-white painted immobile bicycles created by cycling communities and loved ones of victims, are installed roadside to mark the locations of cycling related deaths. Using critical performance ethnography and critical-cultural analysis as methods, I analyze how the ghost bike performs as an artifact of mourning and inspires co-incident performances of grief, activism, and community building and maintenance. As a memorial object used worldwide to represent cycling culture, the ghost bike acts as a social network link that connects a multitude of diverse cycling communities. I …


The Machine Gun Hand: Robots, Performance, And American Ideology In The Twentieth Century, Benjamin Michael Phelan Jan 2017

The Machine Gun Hand: Robots, Performance, And American Ideology In The Twentieth Century, Benjamin Michael Phelan

LSU Doctoral Dissertations

Twentieth-century Marxist philosopher Louis Althusser argued in his famous essay “Ideology and Ideological State Apparatuses” that capitalism reproduces itself by interpellating individuals as subjects. For Althusser, the subject has a dual definition: a person who imagines him or herself to be a free subject who then “chooses” capitalism, and a person who, once they have “chosen” capitalism, gives up their free will to the Subject (Law, God, Authority, the State). This dual definition of the subject mirrors the dual definition of “robot.” A robot is both a mechanical being that moves on its own and a person who acts in …

Specifically, it examined (1) how a sample of social workers obtained the skills necessary to provide culturally appropriate EOL care to clients and families of Middle Eastern descent; (2) the common intervention strategies social workers employ while providing this care; and (3) the recommendations they offer to others who anticipate encountering this population in their own practice. Data collection consisted of in-depth, semi-structured …


Atmospheric Boundary Layer Processes To Mimic Peak Pressures On Low-Rise Buildings: Cfd Versus Full-Scale And Wind Tunnel Measurements, Hamzeh Gol Zaroudi Jan 2017

Atmospheric Boundary Layer Processes To Mimic Peak Pressures On Low-Rise Buildings: Cfd Versus Full-Scale And Wind Tunnel Measurements, Hamzeh Gol Zaroudi

LSU Doctoral Dissertations

Realistic prediction of peak wind pressures is indispensable in a safe design of low-rise buildings. For several decades wind tunnel testing was employed to obtain wind loads on buildings and other structures. However, there is still doubt in the wind engineering community regarding the adequacy of wind tunnels to predict accurately full-scale pressures on low-rise buildings and small-size structures. The recommendations of the American Society of Civil Engineers (ASCE) 7-10 standard for external pressure coefficients, for roof components and cladding (C&C) design are also based on published wind tunnel data. Recent field measurements show significant deviation of full-scale pressures from …


Fluorescent Probe Interrogation Of A Cytoprotective Cancer-Linked Oxidoreductase In Two-Dimensional Human Cell Cultures And Solid Tumor Mimics, Bijeta Prasai Jan 2017

Fluorescent Probe Interrogation Of A Cytoprotective Cancer-Linked Oxidoreductase In Two-Dimensional Human Cell Cultures And Solid Tumor Mimics, Bijeta Prasai

LSU Doctoral Dissertations

Fluorescence molecular imaging is an emerging field with potential to aid in optically guided surgery for cancer treatment. To overcome the drawbacks of always-on fluorescent probes, such as indocyanine green, activatable fluorescent probes are being developed that allow high signal-to-background imaging for better discrimination of cancerous cells from normal cells. For activation, turn-on fluorescent probes rely on the presence of biomarkers such as antibodies, cell-surface receptors or enzymes that are highly specific to tumor cells. hNQO1 (human NAD(P)H: quinone oxidoreductase isoenzyme 1) is considered as one of such cancer-associated biomarkers that are present intracellularly in cancers of multiple origins. It …


Essays On Economic Growth In India, Sujana Kabiraj Jan 2017

Essays On Economic Growth In India, Sujana Kabiraj

LSU Doctoral Dissertations

This dissertation comprises of three distinct studies that contribute to the field of economic growth in India. First, we investigate patterns of growth at the district level (second level administrative units) using radiance calibrated night lights data for 2000-2010. We examine growth both at the aggregated district level, as well as along the rural and urban dimensions. We find evidence of both absolute and conditional convergence, with convergence among rural areas being the primary driver. However, there is no evidence of convergence among urban areas. Moving further along similar lines, we explore the effect of credit shocks, generated by scheduled …
