Long-Term Antagonistic Effect Of Increased Precipitation And Nitrogen Addition On Soil Respiration In A Semiarid Steppe, Hongyan Han, Yue Du, Dafeng Hui, Lin Jiang, Mingxing Zhong, Shiqiang Wan

Biology Faculty Research

Changes in water and nitrogen (N) availability due to climate change and atmospheric N deposition could have significant effects on soil respiration, a major pathway of carbon (C) loss from terrestrial ecosystems. A manipulative experiment simulating increased precipitation and atmospheric N deposition has been conducted for 9 years (2005–2013) in a semiarid grassland in Mongolian Plateau, China. Increased precipitation and N addition interactively affect soil respiration through the 9 years. The interactions demonstrated that N addition weakened the precipitation-induced stimulation of soil respiration, whereas increased precipitation exacerbated the negative impacts of N addition. The main effects of increased precipitation and …

Re-Reading, Re-Writing, And Re-Imagining Texts: Critical Literacy In A Kindergarten Classroom, Meredith Labadie

Dissertations

This qualitative action research study focuses on the integration of critical literacy practices in a kindergarten classroom. Critical literacy recognizes that no texts are neutral, and that authors position their readers in particular ways. Thus critical literacy practices are those concerned with positioning readers to inquire into issues of language and power, and to disrupt, critique, and challenge texts. In this study, critical literacy was brought to life through a curriculum of rereading and revisiting texts over time. The study took place in the researcher’s kindergarten classroom, and follows students’ discussion, written responses, and dramatizations around texts read aloud in …

Estimating Memory Deterioration Rates Following Neurodegeneration And Traumatic Brain Injuries In A Hopfield Network Model, Melanie Weber, Pedro D. Maia, J. Nathan Kutz

Mathematics Faculty Publications - Archive

Neurodegenerative diseases and traumatic brain injuries (TBI) are among the main causes of cognitive dysfunction in humans. At a neuronal network level, they both extensively exhibit focal axonal swellings (FAS), which in turn, compromise the information encoded in spike trains and lead to potentially severe functional deficits. There are currently no satisfactory quantitative predictors of decline in memory-encoding neuronal networks based on the impact and statistics of FAS. Some of the challenges of this translational approach include our inability to access small scale injuries with non-invasive methods, the overall complexity of neuronal pathologies, and our limited knowledge of how networks …

A Role For The Cystic Fibrosis Transmembrane Conductance Regulator In The Nitric Oxide-Dependent Release Of Cl – From Acidic Organelles In Amacrine Cells, Vijai Krishnan, J. Wesley Maddox, Tyler Rodriguez, Evanna Gleason

Faculty Publications

© 2017 the American Physiological Society. γ-Amino butyric acid (GABA) and glycine typically mediate synaptic inhibition because their ligandgated ion channels support the influx of Cl – . However, the electrochemical gradient for Cl – across the postsynaptic plasma membrane determines the voltage response of the postsynaptic cell. Typically, low cytosolic Cl – levels support inhibition, whereas higher levels of cytosolic Cl – can suppress inhibition or promote depolarization. We previously reported that nitric oxide (NO) releases Cl – from acidic organelles and transiently elevates cytosolic Cl – , making the response to GABA and glycine excitatory. In this study, …

Longitudinal Predictors Of Diabetic Ketoacidosis Hospitalizations And Hemoglobin A1c: Examining Adaptation To Type-1 Diabetes In Adolescents, Katherine Semenkovich

Electronic Theses and Dissertations Archive

Diabetic Ketoacidosis (DKA) and elevated hemoglobin A1c (HbA1c) in youth with type-1 diabetes (T1D) can result in significant morbidity and mortality. Elucidating the risk factors for poor glycemic control and DKA hospitalizations is crucial for the refinement and development of prevention and treatment efforts. Based on a conceptual framework, this study used path analysis to evaluate individual and family characteristics, psychosocial responses, and individual and family responses that prospectively predict number of DKA hospitalizations and HbA1c approximately one year after assessment, accounting for socio-demographics. 174 Youth 12-18 years old with T1D (M = 14.78, SD = 1.65) and their caregivers …

Biased Genetic Screen Identifies Novel Genes Involved In Antiviral Defense, Tianyun Long

LSU Doctoral Dissertations

ABSTRACT

RNA interference (RNAi) mediates potent antiviral response across kingdoms. In Caenorhabditis elegans nematodes, antiviral RNAi requires a virus sensor that is conserved in mammals and is amplified by secondary small interfering RNAs that are produced in a Dicer-independent manner.

To better understand worm antiviral RNAi, I carried out a biased genetic screen, aiming to identify novel antiviral RNAi genes. To speed up the gene discovery process, the reporter worms used for this genetic screen were engineered to contain extra copies of 4 known antiviral RNAi genes. Therefore, genetic alleles derived from these 4 genes will be automatically rejected during …

Tumor Suppressor Pdcd4 Attenuates Sin1 Translation To Inhibit Invasion In Colon Carcinoma, Qing Wang, Jiang Zhu, Ya-Wen Wang, Yong Dai, Yanlei Wang, Chi Wang, Jinpeng Liu, Alyson Baker, Nancy H. Colburn, Hsin-Sheng Yang

Toxicology and Cancer Biology Faculty Publications

Programmed cell death 4 (Pdcd4), a tumor invasion suppressor, is frequently downregulated in colorectal cancer and other cancers. In this study, we find that loss of Pdcd4 increases the activity of mammalian target of rapamycin complex 2 (mTORC2) and thereby upregulates Snail expression. Examining the components of mTORC2 showed that Pdcd4 knockdown increased the protein but not mRNA level of stress-activated-protein kinase interacting protein 1 (Sin1), which resulted from enhanced Sin1 translation. To understand how Pdcd4 regulates Sin1 translation, the SIN1 5′ untranslated region (5′UTR) was fused with luciferase reporter and named as 5′Sin1-Luc. Pdcd4 knockdown/knockout significantly increased the translation …

Effect Of Hot Water Conditioning On Microbial Safety And Quality Of In-Shell Pecans, Karuna Kharel

LSU Master's Theses

Hot water conditioning of in-shell pecans is one common practice followed by industries to facilitate shelling. It also acts as a preventive control for potential microbiological contamination that might occur during pre- and post-harvest processes. However, heat treatment may have an effect on the eating quality of nuts. The main objectives of the study were to develop a post-harvest hot water treatment intervention as a kill step to destroy foodborne pathogens on in-shell pecans and evaluate the effect of treatments on physicochemical properties, consumer acceptance and purchase intent of dehulled and roasted pecans. The time (1-5 min) and temperature (70, …

Reconstructing Yeasts Phylogenies And Ancestors From Whole Genome Data, Bing Feng, Yu Ling, Lingxi Zhou, Roufan Xia, Fei Hu, Chao Liu

Faculty Publications

Phylogenetic studies aim to discover evolutionary relationships and histories. These studies are based on similarities of morphological characters and molecular sequences. Currently, widely accepted phylogenetic approaches are based on multiple sequence alignments, which analyze shared gene datasets and concatenate/coalesce these results to a final phylogeny with maximum support. However, these approaches still have limitations, and often have conflicting results with each other. Reconstructing ancestral genomes helps us understand mechanisms and corresponding consequences of evolution. Most existing genome level phylogeny and ancestor reconstruction methods can only process simplified real genome datasets or simulated datasets with identical genome content, unique genome markers, …

Grand Challenges In School Social Work: Collaboration And Constraint In School Social Workers’ Sexuality Support For Children With Disabilities, Sharon J. Bolin, Heidi Adams Rueda, Kristen Faye Linton

Social Work Faculty Publications

Children with disabilities (CWD) face challenges to the development of their sexuality, in part due to a lack of appropriate, tailored sexual education in schools, role ambiguity regarding provision of sexual health services, and widespread discomfort with the topic. However, CWD have unique sexual health needs, an increased vulnerability to sexual and other forms of violence, and desire for skills and knowledge to build relationships. Using a phenomenological lens, authors conducted semistructured interviews with eight school social workers to understand how they are working with other professionals to support sexual and relational health of CWD (ages three to 11). Results …

Processing Motion: Using Code To Teach Newtonian Physics, M. Ryan Massey

Dissertations

Prior to instruction, students often possess a common-sense view of motion, which is inconsistent with Newtonian physics. Effective physics lessons therefore involve conceptual change. To provide a theoretical explanation for concepts and how they change, the triangulation model brings together key attributes of prototypes, exemplars, theories, Bayesian learning, ontological categories, and the causal model theory. The triangulation model provides a theoretical rationale for why coding is a viable method for physics instruction. As an experiment, thirty-two adolescent students participated in summer coding academies to learn how to design Newtonian simulations. Conceptual and attitudinal data was collected using the Force Concept …

Synthesis, Characterization, And Application Of Molybdenum Oxide Nanomaterials, Michael S. Mccrory

USF Tampa Graduate Theses and Dissertations

Nanostructured molybdenum trioxide (MoO₃) was synthesized and used as a precursor in a comparative study, along with commercial MoO₃, to synthesize molybdenum dioxide (MoO₂) nanoparticles. Scanning electron microscope (SEM) images revealed the particles to be approximately 30-50 nm in diameter. X-ray diffraction (XRD) confirmed MoO₃ was fully reduced to MoO₂ in all cases. Time dependent experiments showed that within two hours no traces of MoO₃ are present. All of the experiments showed the materials were excellent absorbent materials, as well as photocatalysts. Both MoO₂ materials performed almost exactly the same, …

Ecology And Biology Of The Redbanded Stink Bug, Piezodorus Guildinii (Westwood) In Louisiana, Anup Bastola

LSU Doctoral Dissertations

The redbanded stink bug, Piezodorus guildinii (Westwood) is an invasive stink bug species that was first documented as a soybean pest in Louisiana during the year 2000. This species continues to expand northward in the MidSouth but information is lacking on its biology and ecology in the U.S. In order to determine P. guildinii’s northern range, studies were designed to investigate the cold tolerance ability of this species. The mean supercooling points of adult P. guildinii ranged from highest -8.3 ± 0.2°C in March to the lowest of -11.0 ± 0.2°C in January. Evaluation of lethal exposure time …

The Role Of Histone H2a.Z Abundance In Modulating Responses To Phosphorus Deficiency In Rice, Sara Zahraeifard

LSU Doctoral Dissertations

Histone variants contribute to chromatin complexity by creating specialized nucleosomes. Here, to investigate the pattern of H2A.Z histone variant distribution and its role in modulating gene expression in rice (Oryza sativa L.), we performed genome-wide profiling of ARP6-dependent H2A.Z deposition in rice seedlings. We demonstrated that under controlled conditions, the majority of H2A.Z deposition is within protein-coding genes (PCG), and the most highly expressed genes are enriched with H2A.Z at their 5’ ends near the transcription start site (TSS), whereas the medium- to low-expressed genes contain H2A.Z across the entire gene. Based on H2A.Z deposition, we categorized genes into …

Coupled Plasmon/Molecule Dynamics Near Core-Shell Nanoparticles: Synthesis, Ultrafast Characterization, And Quantum/Classical Modeling, Holden Tyler Smith

LSU Doctoral Dissertations

In this dissertation, the resonance coupling of chromaphoric dyes adsorbed on the surface of plasmonic nanoparticles (NPs) are investigated using a combined theoretical and experi- mental approach. Colloidal gold, gold-silver core-shell, silver-gold core-shell, and gold-silver- gold core-shell-shell NPs are considered. These NPs are thiolated with mercaptosuccinic acid, and malachite green dyes are adsorbed to the surface of the nanoparticle (NP) via elec- trostatic interactions. Second harmonic generation is used to determine the surface to the isotherm of the molecular dyes to the colloidal nanoparticle surface. Adsorption isotherms show that the SHG intensity increases as the concentration of dye increases, reaching …

Drawing Upon Our Roots And Charism To Address Climate Change And Build Bridges Of Dialogue In Addressing Human Rights And Achieving An Integral Ecology, Leanne M. Jablonski

Biennial Conference: The Social Practice of Human Rights

Although sustainability and human rights are interconnected expressions of Catholic social teaching, the fields and praxis have developed independently. Human rights and other justice issues are rooted in the humanities and social sciences. The idea of sustainability has roots in the humanities and social sciences, but also in natural science and engineering. While sustainability research by scientists and engineers receives support, it is lacking for consideration of human rights and justice concerns, largely because these are viewed as advocacy. More recently, the intersection of these areas, particularly in the examination of the impacts of global climate change, has provided an …

Democratic Civic Engagement: Transformative Local, Inclusive Decision-Making To Achieve Global Peace And Climate Solutions, Leah Ceperley

Biennial Conference: The Social Practice of Human Rights

The UN Sustainable Development Goals call for action on Climate (No. 13) and Strengthening Governance (No. 16) as imperative to transform our world toward one that is resilient, just, and peaceful. Climate change is a global problem, marked frequently in the U.S. by indifference, with far-reaching impacts disproportionately burdening the poor and vulnerable worldwide. Global in scope, its sources, impacts, and fields of action are local. Combating indifference at the local level can strengthen local governance structures, build trust across ideological divides, and shift the conversation from indifference to action.

The Embodiment And Discourses Of A Taboo: #Brelfie, Sarah Beach

Kaleidoscope: A Graduate Journal of Qualitative Communication Research

#brelfie is an online social media trend that seeks to normalize public breastfeeding through exposure. “Brelfies” are “breastfeeding selfies”—in which a mother uploads an image of herself breastfeeding to social media. It is controversial even within the trend itself, as women disagree on how it potentially pressures women to perform motherhood. Much of Western culture views the female breast as a sexual organ, and thus creates norms about how breasts should be functioned and displayed in public. Yet, many others would argue that breastfeeding is the only legitimate use of the female breast and is therefore permissibly exhibited in public. …
