An Atmospheric And Spatiotemporal Examination Of Lightning-Initiated Terrestrial Gamma-Ray Flashes Detected By The Fermi Satellite And Tetra Ii, Deirdre Colleen Smith

LSU Doctoral Dissertations

Terrestrial Gamma-ray Flashes (TGFs) are sub-millisecond bursts of the highest naturally occurring light-energy found within Earth’s atmosphere. TGFs are associated with the electric fields produced in thunderstorms and are geolocated by coincident sferics from lightning strokes. Though billions of lightning strokes occur globally each year, fewer than 1,000 TGFs are detected via satellite and ground-based sensors and only a small fraction are geolocated via sferics.

To date, few studies have focused on individual thunderstorms and climates that produce TGFs. This dissertation examines TGFs from two differing data samples: 1) NASA's Fermi Gamma-Ray Burst Monitor (2013-2018) and 2) The TGF and …

We present the fourth in a series of catalogs of gamma-ray bursts (GRBs) observed with Fermi's Gamma-ray Burst Monitor (Fermi-GBM). It extends the six year catalog by four more years, now covering the 10 year time period from trigger enabling on 2008 July 12 to 2018 July 11. During this time period GBM triggered almost twice a day on transient events, 2356 of which we identified as cosmic GRBs. Additional trigger events were due to solar flare events, magnetar burst activities, and terrestrial gamma-ray flashes. The intention of the GBM GRB catalog series is to provide updated information to the …

Louisiana Beef Cattle Marketing Strategies, Adam Barrilleaux

LSU Master's Theses

The purpose of this study was to estimate the financial costs and returns of selected marketing strategies for cattle producers in the state of Louisiana. Cattle for the project were from the Louisiana State University Agricultural Center and commercial producers. Cattle were grouped by weight and sex and vaccinated, castrated, and handled using standard best management practices. The standard marketing practice for weaned calves in Louisiana of selling weaned animals at local stockyards was compared against alternative marketing of preconditioned calves through video auctions or after feedlot finishing. Feedlot cattle were sold both on live weight value and carcass weight …

Phytosampling Of Ambient Air Particulate Matter (Pm) -New Method Of Pm-Associated Pollution Characterization, Chuqi Guo

LSU Doctoral Dissertations

Ambient air particulate matter (PM) has been documented to be a contributor to a lot of pollution-related health effects. Due to the common anthropogenic origin, PM could be an effective vehicle to carry and deliver many toxic materials, including environmentally persistent free radicals (EPFRs) and polycyclic aromatic hydrocarbons (PAHs) into the human body, thus significantly raise the health risk of PM exposure. Studies of ambient air PM potentially bear artifacts stemming from the collection methods. We investigated the effects of collection methods on the ambient air PM composition and developed a static collection method relying on the particle entrapment by …

Study Of Fundamental Tradeoff Between Deliverable And Private Information In Statistical Inference, Farhang Bayat

LSU Doctoral Dissertations

My primary objective in this dissertation is to establish a framework under which I launch a systematic study of the fundamental tradeoff between deliverable and private information in statistical inference. My research was partly motivated by arising and prevailing privacy concerns of users in many machine learning problems.

In this dissertation, I begin by introducing examples where I am concerned of privacy leakage versus decision utility in statistical inference problems. I then go into further details about what I have achieved in formulating and solving such problems using information theory related metrics in a variety of settings. Both related works …

Acoustic Changes During Passage Reading In Speakers With Parkinson's Disease, Kimberly C. Grubbs

LSU Master's Theses

Purpose: The purpose of this study was to evaluate speech changes in Parkinson’s disease (PD) while reading a passage, using both local (i.e., segment level) and global (i.e., utterance level) acoustic measures.

Methods: 20 speakers participated in the study (10 PD, 10 neurologically healthy controls). The speakers were asked to read The Caterpillar passage in a conversational mode. A total of five acoustic measures were included (local: vowel duration, Euclidean distance between corner vowels and schwa; global: articulation rate, F0/intensity range). These acoustic measures were compared between two sentences located in the two positions within the paragraph, initial and final. …

There's No Place Like Home: Arlene Francis And Domesticity In Doubt, Caroline Argrave

LSU Master's Theses

This thesis examines the life and career of stage, film, and television personality Arlene Francis, in order to add nuance to the understanding of how women broke into the entertainment industry. Francis, rather than brazenly flouting norms, wooed her employers and audience into acceptance by combining her prominent new “power” with comforting old-fashioned norms. The result was a woman doing something patently new while speaking in a way disarmingly familiar. In this way, Francis is reminiscent of other female pioneers, who used a traditionally feminine persona to charm their male colleagues into supporting their leadership, and as a result has …

The Relationship Between The Development Of Communicative Functions In Children With Autism Spectrum Disorders, Isabelle Bankston

LSU Master's Theses

In regard to the assessment of language, it is difficult to determine exact communicative functions that are exhibited early in development that could indicate a prognostic value of verbal abilities and outcomes of children with autism spectrum disorder (ASD). The Verbal Behavioral Milestones Assessment and Placement Program (VB-MAPP, Sundberg, 2008) is frequently used in Applied Behavior Analysis for standard assessment procedures to measure development over time. The current study was designed to use the VB-MAPP to determine a relationship between certain communicative functions (i.e., mand, tact, listener responding, echoic, and intraverbal) that may suggest a correlation in growth in each …

Limitations On Protecting Information Against Quantum Adversaries, Eneet Kaur

LSU Doctoral Dissertations

The aim of this thesis is to understand the fundamental limitations on secret key distillation in various settings of quantum key distribution. We first consider quantum steering, which is a resource for one-sided device-independent quantum key distribution. We introduce a conditional mutual information based quantifier for quantum steering, which we call intrinsic steerability. Next, we consider quantum non-locality, which is a resource for device-independent quantum key distribution. In this context, we introduce a quantifier, intrinsic non-locality, which is a monotone in the resource theory of Bell non-locality. Both these quantities are inspired by intrinsic information and squashed entanglement and are …

Theater Of The Obsessed, Cynthia Sampson

LSU Doctoral Dissertations

Theater of the Obsessed uses fandom to illustrate how audiencing can be a form of queer worldmaking. I begin by establishing that audiencing is a process that takes place over time and is not confined to the seat you’re sitting in while consuming various media. Because audiencing is a nearly invisible process, I turn to fandom and fanworks to demonstrate what some of the other parts look like. From there, I take a mystorical approach. That is, I use mystory to braid my personal audiencing, popular culture examples, and professional scholarship together to create a wide image. What becomes apparent …

Characterization Of Drosophila Boundary Element Associated Factor Beaf-32b Interactions With Transcription Factors And Chromatin Remodeling Complexes., Yuankai Dong

LSU Doctoral Dissertations

BEAF (Boundary Element-Associated Factor) was originally identified as a chromatin domain insulator binding protein, suggesting that it might play a role in linking gene regulation to chromatin organization and dynamics. Genome-wide mapping found that BEAF is usually found near transcription start sites, often of housekeeping genes, suggesting that it might play 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 proteins that interact with BEAF using yeast 2-hybrid assays. Here we focus on three identified transcription factors: Bcd, Scr and Sry-δ. Interactions …

Impacts Of Commercial Biopesticides On Crapemyrtle Bark Scale (Acanthococcus Lagerstroemiae) And Beneficial Insects, Giovana Matos Franco

LSU Master's Theses

The crapemyrtle bark scale (CMBS), Acanthococcus lagerstroemiae (Kuwana) (Hemiptera: Eriococcidae), is an important pest of crapemyrtles, Lagerstromia spp. (Myrtales: Lythraceae) since its damage results in an unpleasant aesthetic. Current CMBS management methods depend heavily on pesticides which impact on beneficial insects. Biopesticides show potential for pest control, host specificity, and low impact towards non-target organisms. The objectives of my thesis were to determine (1) if biopesticides are effective against CMBS infestations when applied in different seasons, and (2) their effects towards coccinellids known to attack CMBS.

To test the efficacy of selected biopesticides, treatments were delivered to potted plants or …

Not All Fun And Gaymes: Technology, Transgression, And Representation Among Gaymers, Kyle Bikowski

LSU Master's Theses

Over the past decade, a new identity has emerged within gaming and gay communities. This identity, Gaymer (Gay-gamer), incorporates elements from both gaming and gay communities, but is accepted by neither. This thesis asks how the interplay of actual and virtual worlds have shaped Gaymer identities, and further asks what the relationship between Gaymers and both the gay and gaming communities are; what elements are conducive to the formation of Gaymer communities; how Gaymers work with or around affordances to assert their identities in virtual and actual spaces; and to what degree representation, either within games as playable characters or …

The Relationship Between Working Memory, Procedural Learning, And Declarative Memory In Children With Specific Language Impairment, Allison Grace Herring

LSU Master's Theses

Background: Children with specific language impairment (SLI) have recently been suggested to have subclinical deficits in executive function skills. The current study seeks to better understand these deficits by exploring the role of nonverbal working memory in word learning and statistical learning in this population. Method: Participants included typically developing children along with children with SLI ranging from ages 8-12 years old. Word learning was assessed using a fast-mapping task, statistical learning was measured using a word-segmentation task, and nonverbal working memory was measured using an N-back task. Results: A significant difference was found between children’s segmentation accuracy scores. …

The Perceptions Of Foster Care Alumni's Experiences With Four-Year Post-Secondary Institutions: A Case For Capital And Field Advantage, June M. Durio

LSU Doctoral Dissertations

ABSTRACT

The focus of this study was to explore, through the lens of Pierre Bourdieu’s constructs of habitus, field, and capital, the post-secondary experiences of foster youth who transitioned out of the Louisiana foster care system. Specifically, this comparable multiple case study sought out to understand how cultural, social, and financial capital influenced the post-secondary educational outcomes of foster care alumni as compared to first-generation and continuing-generation students. Seven common themes emerged from the study: predisposing factors towards post-secondary education; values, knowledge, and skills associated with post-secondary education attainment; informal and formal social networks facilitating post-secondary support; financial resources addressing …

The Effects Of Oral And Venereal Transmission Of Deformed Wing Virus On Honey Bee (Apis Mellifera) Queen And Colony Health, Sarah Lang

LSU Master's Theses

Honey bees are important pollinators necessary for the production of many foods. Managed honey bee colonies have been experiencing high levels of colony loss over the last decade due to a combination of different factors. Parasites, pathogens, and queen failure are repeatedly reported as major causes for colony loss, but there is little research exploring the relationship between honey bee viruses and queens. Deformed wing virus, a major honey bee virus, has a worldwide distribution, is extremely prevalent, and can infect all castes and life stages. Honey bee queens can be infected with the virus through multiple transmission routes …

Applications Of Unmanned Aerial Vehicles For Conducting Mesocarnivore And Breeding Waterfowl Surveys In Southern Manitoba, Jacob Bushaw

LSU Master's Theses

Unmanned aerial vehicles (UAVs) are becoming an increasingly important tool for wildlife surveys and equipping UAVs with thermal imaging cameras could make these surveys even more effective. In my thesis I examined the feasibility of using a UAV equipped with a thermal imaging camera to conduct mesocarnivore surveys, search for duck nests built over water, and conduct duck brood surveys in southern Manitoba.

For my first objective, I conducted nighttime mesocarnivore surveys with the UAV and thermal camera. I used a modified point-count survey from six waypoints and surveyed 29.5 ha in each replicate. I conducted a total of 200 …

Schnittke, Gubaidulina, And Pärt: Religion And Spirituality During The Late Thaw And Early Perestroika, Aleksandra Drozzina

LSU Doctoral Dissertations

The dissertation explores the music of three major Soviet composers—Alfred Schnittke, Sofia Gubaidulina, and Arvo Pärt—against the backdrop of the ever-changing Soviet rule (after Stalin’s death in 1953). I reevaluate the composers’ religious and spiritual beliefs expressed in their works during the 1970s–1980s. Three works are presented as case studies and analyzed in-depth: Schnittke’s Concerto for Choir (1984–85), Gubaidulina’s Sieben Worte (1982), and Pärt’s Stabat Mater (1985). Although under Nikita Khrushchev’s rule (1953–64), governmental censorship began to slowly loosen, this particular group of composers continued to experience a considerable degree of oppression and censorship from the Soviet government until and …
