The Influence Of Housing In A Content-Based Residential College And Selected Demographic Characteristics On The Retention Of Students Enrolled In A College Of Business At A Research University (Ru/Vh) In The Southern Region Of The United States, Reuben Twijukye

LSU Doctoral Dissertations

“Statistics indicate that more than 40 percent of all college entrants leave higher education without earning a degree, 75 percent of these students drop out in the first two years of college, and institutions can expect that 56 percent of a typical entering class cohort will not graduate from that college ”(DeShields , Kara, , & Kaynak, P.129). Therefore, the primary purpose of this study was to determine the influence of housing in the College of Business content-based residential college (CBRC) and selected demographics on the retention in the fifth semester of students in the College of Business.

Characterizing The Epidemiology Of Bluetongue And Epizootic Hemorrhagic Disease Virus In Louisiana, Michael Edward Becker

LSU Doctoral Dissertations

Bluetongue virus (BTV) and Epizootic Hemorrhagic Disease Virus (EHDV) are arthropod-borne viruses (Reoviridae; Orbivirus) transmitted by biting midges in the genus Culicoides. These viruses cause hemorrhagic disease and induce serious morbidity and mortality rates in wild and captive deer. Cattle are normally asymptomatic but serve as the reservoir/amplifying host for these viruses and play an important role in the transmission cycle. The objectives of this study were to characterize the epidemiology of these viruses as they relate to white-tailed deer and cattle, evaluate different trap types for collecting Culicoides midges, and determine if these viruses can be detected …

Gauge-Invariant Bounce From Loop Quantum Gravity, Klaus Liegener, Parampreet Singh

Faculty Publications

We present a gauge-invariant treatment of singularity resolution using loop quantum gravity techniques with respect to local SU(2) transformations. Our analysis reveals many novel features of quantum geometry which were till now hidden in models based on non-gauge-invariant discretizations. Quantum geometric effects resolve the big bang singularity replacing it with a non-singular bounce when spacetime curvature reaches Planckian value. The bounce is found to be generically asymmetric in the sense that pre-bounce and post-bounce branches are not mirrored to each other and effective constants, such as Newton's constant, are rescaled across the bounce. Furthermore, in the vicinity of the bounce, …

Convergent Evolution Of Olfactory And Thermoregulatory Capacities In Small Amphibious Mammals, Quentin Martinez, Julien Clavel, Jacob A. Esselstyn, Anang S. Achmadi, Camille Grohé, Nelly Pirot, Pierre Henri Fabre

Faculty Publications

Olfaction and thermoregulation are key functions for mammals. The former is critical to feeding, mating, and predator avoidance behaviors, while the latter is essential for homeothermy. Aquatic and amphibious mammals face olfactory and thermoregulatory challenges not generally encountered by terrestrial species. In mammals, the nasal cavity houses a bony system supporting soft tissues and sensory organs implicated in either olfactory or thermoregulatory functions. It is hypothesized that to cope with aquatic environments, amphibious mammals have expanded their thermoregulatory capacity at the expense of their olfactory system. We investigated the evolutionary history of this potential trade-off using a comparative dataset of …

Faculty Publications

We present results from offline searches of Fermi Gamma-ray Burst Monitor (GBM) data for gamma-ray transients coincident with the compact binary coalescences observed by the gravitational-wave (GW) detectors Advanced LIGO and Advanced Virgo during their first and second observing runs. In particular, we perform follow-up for both confirmed events and low significance candidates reported in the LIGO/Virgo catalog GWTC-1. We search for temporal coincidences between these GW signals and GBM-triggered gamma-ray bursts (GRBs). We also use the GBM Untargeted and Targeted subthreshold searches to find coincident gamma-rays below the onboard triggering threshold. This work implements a refined statistical approach by …

Genetic Dissection Of Heat-Responsive Physiological Traits To Improve Adaptation And Increase Yield Potential In Soft Winter Wheat, Sumit Pradhan, Md Ali Babar, Guihua Bai, Jahangir Khan, Dipendra Shahi, Muhsin Avci, Jia Guo, Jordan Mcbreen, Senthold Asseng, Salvador Gezan, Byung Kee Baik, Ann Blount, Stephen Harrison, Suraj Sapkota, Paul St. Amand, Sanju Kunwar

Faculty Publications

Background: Climate change, including higher temperatures (HT) has a detrimental impact on wheat productivity and modeling studies predict more frequent heat waves in the future. Wheat growth can be impaired by high daytime and nighttime temperature at any developmental stage, especially during the grain filling stage. Leaf chlorophyll content, leaf greenness, cell membrane thermostability, and canopy temperature have been proposed as candidate traits to improve crop adaptation and yield potential of wheat under HT. Nonetheless, a significant gap exists in knowledge of genetic backgrounds associated with these physiological traits. Identifying genetic loci associated with these traits can facilitate physiological breeding …

Imperfect Recollisions In High-Harmonic Generation In Solids, Lun Yue, Mette B. Gaarde

Faculty Publications

We theoretically investigate high-harmonic generation in hexagonal boron nitride with linearly polarized laser pulses. We show that imperfect recollisions between electron-hole pairs in the crystal give rise to an electron-hole-pair polarization energy that leads to a double-peak structure in the subcycle emission profiles. An extended recollision model (ERM) is developed that allows for such imperfect recollisions, as well as effects related to Berry connections, Berry curvatures, and transition-dipole phases. The ERM illuminates the distinct spectrotemporal characteristics of harmonics emitted parallel and perpendicularly to the laser polarization direction. Imperfect recollisions are a general phenomenon and a manifestation of the spatially delocalized …

Theoretical Investigation Of Fundamental Cathode Processes In Metal-02 Batteries, Saurin Hiren Rawal

LSU Doctoral Dissertations

In this thesis we theoretically explore the different fundamental phenomena associated with metal-air batteries (where the metal can be Li, Na or K) using first principles density functional theory. We start by investigating the adsorption of the starting reactants/primary intermediates i.e. metal superoxides and superoxide anion on Au(111) and Au(211). We elucidate the influence of electric fields and the importance of including explicit solvents on the adsorption energy of these intermediates. We show that these effects are considerable and should be included for future reaction modeling of these batteries. Following this we investigate the reaction of M⁺ and O …

The charge-conjugation and parity-reversal (CP) symmetry of fundamental particles is a symmetry between matter and antimatter. Violation of this CP symmetry was first observed in 19641, and CP violation in the weak interactions of quarks was soon established2. Sakharov proposed3 that CP violation is necessary to explain the observed imbalance of matter and antimatter abundance in the Universe. However, CP violation in quarks is too small to support this explanation. So far, CP violation has not been observed in non-quark elementary particle systems. It has been shown that CP violation in leptons could generate the matter–antimatter disparity through a process …

Energetics Of Interfacial Interactions Of Hydrocarbon Fluids With Kerogen And Calcite Using Molecular Modeling, Zelong Zhang, Haoran Liu, Jianwei Wang

Faculty Publications

© 2020 American Chemical Society. Understanding of the fluid-rock interactions is essential to characterize the behavior of petroleum fluids in reservoir formations. Such knowledge is difficult to obtain due to the heterogeneous nature of hydrocarbon systems. This study investigated the interactions of light oil molecules with kerogen and calcite using molecular dynamics simulations. Specifically, octane and octanthiol were used as model molecules for non-polar and polar oil compounds; a kerogen fragment molecule was employed as the building block for kerogen, the major constituent of reservoir rock organics; calcite was used as a model system for hydrophilic materials in reservoir rocks. …

Baton Rouge Slam!: An Obituary For Summer 2016: A Critical Performance Ethnography Of Eclectic Truth Poetry Slam, Joshua Hamzehee

LSU Doctoral Dissertations

This critical performance ethnography presents the theory, methodology, and practice surrounding the fieldwork, scripting, and performance of Baton Rouge SLAM!: An Obituary for Summer 2016. As participant-observer, director, and co-performer, I unpack social drama, performance ethnography, and slam culture by employing a lens rooted in critical race theory. Local poets permitted me to de- and re-contextualize their interviews into ensemble scenes and theatricalize their slam poems about the recent summer’s charged events. One year later, this involved and embodied process of ethnographic bricolage became the ensemble cast performance of Baton Rouge SLAM!: An Obituary for Summer 2016. Community members and …

Hysteresis And Beating Phenomena In Loop Quantum Cosmology, John L. Dupuy, Parampreet Singh

Faculty Publications

Difference in pressure during expansion and contraction stages of the cosmic evolution can result in a hysteresislike phenomenon in nonsingular cyclic models sourced with a massive scalar field. We discuss this phenomenon for spatially closed isotropic spacetimes in loop quantum cosmology (LQC) for a quadratic and a coshlike potential, with and without a negative cosmological constant using an effective spacetime description of the underlying quantum geometry. Two inequivalent loop quantizations are investigated-one based on holonomies of the Ashtekar-Barbero connection using closed loops, and another based on the connection operator. Due to the underlying quantum geometric effects, both of the models …

Primordial Power Spectrum From The Dressed Metric Approach In Loop Cosmologies, Bao Fei Li, Parampreet Singh, Anzhong Wang

Faculty Publications

We investigate the consequences of different regularizations and ambiguities in loop cosmological models on the predictions in the scalar and tensor primordial spectrum of the cosmic microwave background using the dressed metric approach. Three models, standard loop quantum cosmology (LQC), and two modified loop quantum cosmologies (mLQC-I and mLQC-II) arising from different regularizations of the Lorentzian term in the classical Hamiltonian constraint are explored for chaotic inflation in spatially flat Friedmann-Lemaître-Robertson-Walker (FLRW) universe. In each model, two different treatments of the conjugate momentum of the scale factor are considered. The first one corresponds to the conventional treatment in dressed metric …

We present the results from a search for gravitational-wave transients associated with core-collapse supernovae observed within a source distance of approximately 20 Mpc during the first and second observing runs of Advanced LIGO and Advanced Virgo. No significant gravitational-wave candidate was detected. We report the detection efficiencies as a function of the distance for waveforms derived from multidimensional numerical simulations and phenomenological extreme emission models. The sources with neutrino-driven explosions are detectable at the distances approaching 5 kpc, and for magnetorotationally driven explosions the distances are up to 54 kpc. However, waveforms for extreme emission models are detectable up to …

Heidegger's Phenomenology: 1919-1929, Joseph Arthur Giavotella

LSU Master's Theses

In this work, I show Martin Heidegger’s development of the phenomenological method from 1919 to 1929 as his main approach to all philosophical inquiry. In Chapter 1: Phenomenology as the Hermeneutics of Factical Life, I first show how Heidegger begins his philosophical career in 1919 with lectures that describe phenomenology as an ‘original science’ that seeks to study the structural character of life in itself. Through the four sub-sections of Chapter 1, I show how Heidegger continues to formulate distinct stages of phenomenological methodology through these early lectures that aid in his task to continue the explication of life through …
