The Language Of Rats: Unwelcome Animals And Interspecies Connection In Contemporary Anglophone Fiction, Kieran Leigh Lyons May 2020

The Language Of Rats: Unwelcome Animals And Interspecies Connection In Contemporary Anglophone Fiction, Kieran Leigh Lyons

LSU Doctoral Dissertations

The Language of Rats: Unwelcome Animals and Interspecies Connection in Global Contemporary Fiction consists of three essays examining the representation of what I call unwelcome animals in contemporary Anglophone novels from the United States, Nigeria, and India. These animals often live alongside humans yet are perceived as threats or annoyances. Literary depictions of this fraught relationship reveal, and sometimes critique, the intellectual structures that shape how we understand and represent interspecies connections. This dissertation contributes to our understanding of the interspecies dimensions of contemporary fiction by bringing together the fields of environmental criticism, animal studies, postcolonialism, and U.S. Southern studies. …

Estuarine Submerged Aquatic Vegetation Habitat Provides Organic Carbon Storage Across A Shifting Landscape, Eva R. Hillmann, Victor H. Rivera-Monroy, J. Andrew Nyman, Megan K. La Peyre May 2020

Estuarine Submerged Aquatic Vegetation Habitat Provides Organic Carbon Storage Across A Shifting Landscape, Eva R. Hillmann, Victor H. Rivera-Monroy, J. Andrew Nyman, Megan K. La Peyre

Faculty Publications

Submerged aquatic vegetation (SAV) thrives across the estuarine salinity gradient providing valuable ecosystem services. Within the saline portion of estuaries, seagrass areas are frequently cited as hotspots for their role in capturing and retaining organic carbon (Corg). Non-seagrass SAV, located in the fresh to brackish estuarine areas, may also retain significant soil Corg, yet their role remains unquantified. Given rapidly occurring landscape and salinity changes due to human and natural disturbances, landscape level carbon pool estimates from estuarine SAV habitat blue carbon estimates are needed. We assessed Corg stocks in SAV habitat soils from estuarine freshwater to saline habitats (interior …

Evaluation Of Undrained Shear Strength Of Soil, Ultimate Pile Capacity And Pile Set-Up Parameter From Cone Penetration Test (Cpt) Using Artificial Neural Network (Ann), Md Ariful Hassan Mojumder May 2020

Evaluation Of Undrained Shear Strength Of Soil, Ultimate Pile Capacity And Pile Set-Up Parameter From Cone Penetration Test (Cpt) Using Artificial Neural Network (Ann), Md Ariful Hassan Mojumder

LSU Master's Theses

Over the years, numerous design methods were developed to evaluate the undrained shear strength, Su, ultimate pile capacity and pile set-up parameter, A. In recent decades, the emphasis was given to the in-situ cone and piezocone penetration tests (CPT, PCPT) to estimate these parameters since CPT/PCPT has been proven to be fast, reliable and cost-effective soil investigation method. However, because of the paucity of a vivid comprehension of the physical problem, some of the developed methods incorporate correlation assumptions which might compromise the consistent accuracy. In this study, the Artificial Neural Network (ANN) was exerted using CPT data …

Predictive Modeling Of Asynchronous Event Sequence Data, Jin Shang

LSU Doctoral Dissertations

Large volumes of temporal event data, such as online check-ins and electronic records of hospital admissions, are becoming increasingly available in a wide variety of applications including healthcare analytics, smart cities, and social network analysis. Those temporal events are often asynchronous, interdependent, and exhibiting self-exciting properties. For example, in the patient's diagnosis events, the elevated risk exists for a patient that has been recently at risk. Machine learning that leverages event sequence data can improve the prediction accuracy of future events and provide valuable services. For example, in e-commerce and network traffic diagnosis, the analysis of user activities can be …

Examining Relationships Between Early Childcare Teachers' Adult Attachment Orientations And Quality Of Interaction In The Infant Classroom, Alexandra Morris Benoit

LSU Doctoral Dissertations

Over the past several decades, women have entered the workforce in increasing numbers. This has led to the majority of infants and young children being cared for outside of the home by extra-familial caregivers. Research has shown the benefits that quality childcare can have on the developmental trajectories of children, as well as the detrimental effects that can be seen when children experience low quality care. Further, children are particularly vulnerable in the first year of life when they are establishing attachment bonds with their primary caregivers. With the long hours that many spend in the care of childcare workers, …


The Strange Death Of American Democracy: Judicial Supremacy And The New Constitutional Politics, 1910-1916, Logan Istre May 2020

The Strange Death Of American Democracy: Judicial Supremacy And The New Constitutional Politics, 1910-1916, Logan Istre

LSU Master's Theses

American constitutional politics reached a crisis point during the Progressive Era. At the center of the crisis was the question as to what the Constitution meant and who had the final word in interpreting it: The Supreme Court or the People of the United States. That fundamental question came to a head in the presidential election of 1912. The result of that contest was the confirmation of judicial supremacy in constitutional interpretation and a mortal blow the nation’s traditional popular constitutional politics. The ensuring consensus of judicial supremacy has defined the nation’s constitutional politics since, which has resulted in the …

Plant Genome Size Influences Stress Tolerance Of Invasive And Native Plants Via Plasticity, Laura A. Meyerson, Petr Pyšek, Magdalena Lučanová, Sara Wigginton, Cao Tri Tran, James T. Cronin

Faculty Publications

© 2020 The Authors. Plant genome size influences the functional relationships between cellular and whole-plant physiology, but we know little about its importance to plant tolerance of environmental stressors and how it contributes to range limits and invasion success. We used native and invasive lineages of a wetland plant to provide the first experimental test of the Large Genome Constraint Hypothesis (LGCH)—that plants with large genomes are less tolerant of environmental stress and less plastic under stress gradients than plants with small genomes. We predicted that populations with larger genomes would have a lower tolerance and less plasticity to a …

Structure Gauges And Laser Gauges For The Semiconductor Bloch Equations In High-Order Harmonic Generation In Solids, Lun Yue, Mette B. Gaarde May 2020

Structure Gauges And Laser Gauges For The Semiconductor Bloch Equations In High-Order Harmonic Generation In Solids, Lun Yue, Mette B. Gaarde

Faculty Publications

The semiconductor Bloch equations (SBEs) are routinely used for simulations of strong-field laser-matter interactions in condensed matter. In systems without inversion or time-reversal symmetries, the Berry connections and transition dipole phases (TDPs) must be included in the SBEs, which in turn requires the construction of a smooth and periodic structure gauge for the Bloch states. Here, we illustrate a general approach for such a structure-gauge construction for topologically trivial systems. Furthermore, we investigate the SBEs in the length and velocity gauges and discuss their respective advantages and shortcomings for the high-harmonic generation (HHG) process. We find that in cases where …

X-ray transition radiation detectors (TRDs) are used for particle identification in both high energy physics and astroparticle physics. In most of the detectors, emission of the X-ray transition radiation (TR) starts at Lorentz factors above γ∼500 and reaches saturation at γ∼2÷3⋅103. However, many experiments require particle identification up to γ∼105, which is very difficult to achieve with conventional detectors. Semiconductor pixel detectors offer a unique opportunity for precise simultaneous measurements of spectral and angular parameters of TR photons. Test beam studies of the energy and the angular distributions of TR photons emitted by electrons and muons of different momenta crossing …

Promoter-Proximal Chromatin Domain Insulator Protein Beaf Mediates Local And Long-Range Communication With A Transcription Factor And Directly Activates A Housekeeping Promoter In Drosophila, Yuankai Dong, S. V. Satya Prakash Avva, Mukesh Maharjan, Janice Jacobi, Craig M. Hart

Faculty Publications

Copyright © 2020 by the Genetics Society of America BEAF (Boundary Element-Associated Factor) was originally identified as a Drosophila melanogaster chromatin domain insulator-binding protein, suggesting a role in gene regulation through chromatin organization and dynamics. Genome-wide mapping found that BEAF usually binds near transcription start sites, often of housekeeping genes, suggesting a role in promoter function. This would be a nontraditional role for an insulator-binding protein. To gain insight into molecular mechanisms of BEAF function, we identified interacting proteins using yeast two-hybrid assays. Here, we focus on the transcription factor Serendipity d (Sry-d). Interactions were confirmed in pull-down experiments using …

Faculty Publications

© 2020 The Authors. Evolution © 2020 The Society for the Study of Evolution. Cave adaptation has evolved repeatedly across the Tree of Life, famously leading to pigmentation and eye degeneration and loss, yet its macroevolutionary implications remain poorly understood. We use the North American amblyopsid fishes, a family spanning a wide degree of cave adaptation, to examine the impact of cave specialization on the modes and tempo of evolution. We reconstruct evolutionary relationships using ultraconserved element loci, estimate the ancestral histories of eye-state, and examine the impact of cave adaptation on body shape evolution. Our phylogenomic analyses provide a …


The Triple Oxygen Isotope Composition Of Precambrian Chert, Frasier L. Liljestrand, Andrew H. Knoll, Nicholas J. Tosca, Phoebe A. Cohen, Francis A. Macdonald, Yongbo Peng, David T. Johnston May 2020

The Triple Oxygen Isotope Composition Of Precambrian Chert, Frasier L. Liljestrand, Andrew H. Knoll, Nicholas J. Tosca, Phoebe A. Cohen, Francis A. Macdonald, Yongbo Peng, David T. Johnston

Faculty Publications

© 2020 Elsevier B.V. The temperature and chemistry of early seawater have both been inferred from the isotopic composition of Precambrian chert (SiO2), a precipitated mineral formed on or within marine sediments. The δ18O of chert shows a robust quasi-linear increase through time - a signal that has been interpreted in a number of conflicting ways. For example, changing δ18O has been hypothesized to reflect the product of cooling surface ocean temperatures, a signature of evolving seawater δ18O composition, or the product of later stage diagenesis (where measured δ18O reflects the composition of diagenetic fluids). We suggest this uncertainty can …

Chronic stress causes dysregulations of mood and energy homeostasis, but the neurocircuitry underlying these alterations remain to be fully elucidated. Here we demonstrate that chronic restraint stress in mice results in hyperactivity of pro-opiomelanocortin neurons in the arcuate nucleus of the hypothalamus (POMCARH neurons) associated with decreased neural activities of dopamine neurons in the ventral tegmental area (DAVTA neurons). We further revealed that POMCARH neurons project to the VTA and provide an inhibitory tone to DAVTA neurons via both direct and indirect neurotransmissions. Finally, we show that photoinhibition of the POMCARH→VTA circuit in mice increases body weight and food intake, …

Though individual differences in arterial carbon dioxide and oxygen levels inherently exist, the degree of their influence on cerebral vascular reactivity (CVR) is less clear. We examined the reproducibility of BOLD signal changes to an iso-oxic ramping PetCO2 protocol. CVR changes were induced by altering PetCO2 while holding PetO2 constant using a computer-controlled sequential gas delivery (SGD) device. Two MRI scans, each including a linear change in PetCO2, were performed using a 3-Tesla (3T) scanner. This ramp sequence consisted of 1 min at 30 mmHg followed by 4 min period during where PetCO2 was linearly increased from 30 to 50 …

Single nucleotide polymorphisms (SNPs) are highly abundant, amendable to high-throughput genotyping, and useful for a number of breeding and genetics applications in crops. SNP frequencies vary depending on the species and populations under study, and therefore target SNPs need to be carefully selected to be informative for each application. While multiple SNP genotyping systems are available for rice (Oryza sativa L. and its relatives), they vary in their informativeness, cost, marker density, speed, flexibility, and data quality. In this study, we report the development and performance of the Cornell-IR LD Rice Array (C7AIR), a second-generation SNP array containing 7,098 markers …

Maize (Zea mays L.) is one of the major crops susceptible to Aspergillus flavus infection and subsequent contamination with aflatoxins, the most potent naturally produced carcinogenic secondary metabolites. This pathogen can pose serious health concerns and cause severe economic losses due to the Food and Drug Administration (FDA) regulations on permissible levels of aflatoxins in food and feed. Although biocontrol has yielded some successes in managing aflatoxin contamination, enhancing crop resistance is still the preferred choice of management for long-term sustainability. Hence, host induced gene silencing (HIGS) strategy was explored in this study. The A. flavus gene aflM encoding versicolorin …

T2K observes 15 candidate electron antineutrino events with a background expectation of 9.3 events. Including information from the kinematic distribution of observed events, the hypothesis of no electron antineutrino appearance is disfavored with a significance of 2.40σ and no discrepancy between data and PMNS predictions is found. A complementary analysis that introduces an additional free parameter which allows non-PMNS values of electron neutrino and antineutrino appearance also finds no discrepancy between data …
