The Impact Of Grout Specimen Geometry On Compressive Strength Results, Leo J. Keegan

LSU New Orleans Theses and Dissertations

Some project standards specify that grout be tested in accordance with ASTM C1019 “Standard Test Method for Sampling and Testing Grout for Masonry”. This is true even when the grout is not being used for the purpose of masonry construction, such as bridge riser bearing plates and anchoring applications, amongst others. In these instances, the grout compressive strength samples cannot be formed in accordance with ASTM C1019, as there are no masonry units.

The purpose of this project was to evaluate the accuracy of sampling grout in accordance with ASTM C109 “Standard Test Method of Hydraulic Cement Mortars (Using 2-inch …

The Trampling Of The White Rose: The Jacobite Impact On British Politics, Joseph Kurtz

Graduate Theses

During the Glorious Revolution, King James II of England and VII of Scotland was deposed, and the main line of the House of Stuart, along with the concept of divine right monarchy and the acceptance of Catholicism, were swept aside in Great Britain. In exile, the remaining heads of the House of Stuart relied on sympathetic Catholic powers or domestic loyalists known as Jacobites. These Jacobites developed distinct versions of their Jacobitism in England, Scotland, and Ireland. Real or perceived Jacobite interference was a constant variable in the rivalry of the Tories and Whigs. The Catholic powers of France, Spain, …

The Management Of Non-Ige-Mediated Allergies In Human Milk-Fed Infants, Sarah Kelly Rowe

Graduate Theses

Background: Non-IgE (immunoglobulin E)-mediated food allergies (FA) present diagnostic and management challenges despite guidelines due to knowledge gaps amongst clinicians. Given that 60% of food protein-induced allergic proctocolitis (FPIAP) cases occur in breast-fed infants, maternal elimination diets are routinely prescribed to manage allergy symptoms. The implications of maternal dietary eliminations extend beyond maternal nutrition to consideration of infant nutrition and feeding skill acquisition.

Methods: A survey-based retrospective, cross-sectional study sought to identify dietary triggers and symptom management techniques practiced by (n=59) lactating mothers of infants with confirmed and suspected cases of non-IgE FA in the United States. Statistical significance was …

Black Joining The Ranks Of White: Black Slaveowning In 1800s South Carolina, Zachary M. Saddow

Graduate Theses

Exploring the lives and impact of the Black slaveholders in Antebellum South Carolina is a highly overlooked subject in a sensitive area. The idea of a Black slaveholder stands contrary to the widely held belief of slavery held by a majority in the United States. This realization is also startling as most slaveholders were White, with those in bondage being Black. These Black slaveholders actively took part in the system of slavery including the buying and selling of slaves, the production of cash crops, and even support for the eventual Confederacy. Although many began their life in chains, Black future …

Inner Portraits, Bethany Salisbury

Graduate Theses

This paper investigates the many interconnected layers of women’s mental health through portraiture and how animal and plant symbolism can represent the way women's hormones and bodily health affect their mental health. I reveal how the artwork created presents these connections and inner mental health narratives to the viewer, creating a space of empathy, destigmatization, and self-reflection. This body of portraiture art connects five women through a series of both two-and three-dimensional portraits based on interviews using my own adaptation of Sara Lawrence-Lightfoots’ (1983) portrait methodology.

Women and non-binary individuals have always dealt with difficult interactions of bodily and mental …

Synthesis, Radiolabeling And Evaluation Of A Suite Of Tracers With 44Sc For Detecting Extracellular Dna, Zhiyao Li

McKelvey School of Engineering Graduate Student Theses & Dissertations

Neutrophil extracellular traps involve the rapid translocation of DNA to the outside of the cell under certain stimuli. This structure forms a fibrous network that is able to limit the spread of pathogens and to kill microorganisms. It has also been shown to be present in various pathological processes such as inflammation, autoimmune diseases, and cancer metastasis. Currently, the formation process of NETs in vivo is being extensively studied. However noninvasive detection and quantitation has yet to be achieved. A class of PET tracers are described here that consists of a DNA dye as the backbone that is labeled with …

Optimization Of Porosity In Cold Spray Produced Copper And Zinc Coatings, Cameron Hughes

Graduate Theses & Non-Theses

Since its invention in 1981, the cold spray (CS) additive manufacturing (AM) process has been studied and optimized to produce well-adhered, dense material coatings. CS can operate at a wide range of temperatures if the feed material remains in a solid state. Copper and zinc were studied to characterize and understand the effects of heating element voltage, travel speed, and standoff distance on deposit porosity, grain size, microhardness, and coating thickness. Samples were sprayed on 3.2 mm x 25 mm x 150 mm 6061 aluminum substrates. Sections were taken from the middle of the samples to represent steady-state conditions. Sample …

Predicting The Damage Behavior And Fracture Propagation In A 3d-Printed Synthetic Rock Material With The Distinct Element Method (Pfc3d) And Hybrid Finite-Discrete Element Method (Irazu3d), Frankie Johnston

Graduate Theses & Non-Theses

The ability to monitor and predict the evolution of rock damage and fracture is key for creating reliable and sustainable civil infrastructure. Rock crack propagation is a complex process that is dependent on material properties such as tensile strength, compressive strength, density, elastic modulus, Poisson's ratio, friction coefficient, cohesion, and specimen conditions such as preexisting microcracks, particle size distribution, and mineral distribution. In conjunction with the 56th US Rock Mechanics/Geomechanics Symposium, researchers primarily at Purdue University organized the Damage Mechanics Challenge to determine the current state and future direction of the rock modeling community’s ability to simulate rock crack formation. …

Moving Towards Principles-Based Accounting Standards: The Impact Of The New Revenue Standard On The Quality Of Accrual Accounting, He, Huiyu

Dissertations and Theses Collection (Open Access)

The new revenue standard (ASU 2014-09, codified in ASC 606 and ASC 340-40) establishes a comprehensive framework on accounting for contracts with customers and replaces most existing revenue recognition rules. The new guidance removes the inconsistencies and weaknesses of legacy guidance, while is more principles-based and requires more managerial judgements. Using as-reported data from structured filings to construct aggregate accruals that are potentially affected by the new revenue standard (i.e., sales-related accruals), I find that the new revenue standard increases the quality of sales-related accruals, as measured by future cash flow predictability. The increased cash flow predictability comes not only …

The Role Of Disclosure In Defi Markets: Evidence From Twitter, Amanda Aw Yong

Dissertations and Theses Collection (Open Access)

Decentralized Finance (DeFi) platforms use self-executing smart contracts to provide financial services and are programmed to automatically post all transactions on the public blockchain. Notwithstanding this public availability of blockchain information, DeFi platforms also aggregate these transactions and disclose the summarized blockchain information on their Twitter accounts. This paper studies whether and how voluntary disclosure of blockchain information plays a role in the transparent DeFi market. I find that the number of blockchain-related tweets is associated both with an increase in the platform’s Total Value Locked (TVL) and with an increase in the unique number of platform users. The relationship …

Connecting The Dots For Contextual Information Retrieval, Pei-Chi Lo

Dissertations and Theses Collection (Open Access)

There are many information retrieval tasks that depend on knowledge graphs to return contextually relevant result of the query. We call them Knowledgeenriched Contextual Information Retrieval (KCIR) tasks and these tasks come in many different forms including query-based document retrieval, query answering and others. These KCIR tasks often require the input query to contextualized by additional facts from a knowledge graph, and using the context representation to perform document or knowledge graph retrieval and prediction. In this dissertation, we present a meta-framework that identifies Contextual Representation Learning (CRL) and Contextual Information Retrieval (CIR) to be the two key components in …

Document Graph Representation Learning, Ce Zhang

Dissertations and Theses Collection (Open Access)

Much of the data on the Web can be represented in a graph structure, ranging from social and biological to academic and Web page graphs, etc. Graph analysis recently attracts escalating research attention due to its importance and wide applicability. Diverse problems could be formulated as graph tasks, such as text classification and information retrieval. As the primary information is the inherent structure of the graph itself, one promising direction known as the graph representation learning problem is to learn the representation of each node, which could in turn fuel tasks such as node classification, node clustering, and link prediction. …

Essays On Large Panel Data Models With Two-Way Heterogeneity, Yiren Wang

Dissertations and Theses Collection (Open Access)

This dissertation consists of two papers that contribute to the estimation and inference theory of the panel data models with two-way slope heterogeneity. The first paper considers the panel quantile regression model with slope heterogeneity along both individuals and time. By modelling this two-way heterogeneity with the low-rank slope matrix, the slope coefficient can be estimated via the nuclear norm regularization followed by sample-splitting, row- and column-wise quantile regression, and debiasing. The inferential theory for the final slope estimator along with its factor and factor loading is derived. Two specification tests are proposed: one tests whether the slope coefficient is …

Dissertation On The Impacts Of Floods And Trade War On The Chinese Economy, Fan Zheng

Dissertations and Theses Collection (Open Access)

In the first chapter of the dissertation, we study the impact of floods on microlevel firm performances in China for the period 2000-2009. Among the first in the literature, we identify the flood exposure directly at the firm level by combining the high-resolution satellite-observed inundation areas with the geocoded firm locations. We find that being hit by a flood is associated with an annual loss to output and productivity of around 6% and 5%, respectively, which persists in the long run. The impacts of floods extend to non-inundated firms in neighborhoods (of 4 kilometres in radius), but the negative effects …

Learning Dynamic Multimodal Networks, Meng Kiat Gary Ang

Dissertations and Theses Collection (Open Access)

Capturing and modeling relationship networks consisting of entity nodes and attributes associated with these nodes is an important research topic in network or graph learning. In this dissertation, we focus on modeling an important class of networks present in many real-world domains. These networks involve i) attributes from multiple modalities, also known as multimodal attributes; ii) multimodal attributes that are not static but time-series information, i.e., dynamic multimodal attributes, and iii) relationships that evolve across time, i.e., dynamic networks. We refer to such networks as dynamic multimodal networks in this dissertation.

An example of a static multimodal network is one …

Driving Forces Of Mining Outsourcing: Evidence From China, Bingxu Zheng

Dissertations and Theses Collection (Open Access)

The outsourcing of services by mining enterprises has become a significant global trend. Classic studies have demonstrated that outsourcing can help enterprises obtain professional services, improving productivity and reducing production costs. However, as a transitional economy, China has its unique characteristics regarding the driving forces of service outsourcing. By employing a case study method, one mining service outsourcing provider, and five mining enterprises' interviews and archival data, this study constructs a theory to identify the driving forces and mechanisms of mining enterprises' choice of service outsourcing and a logic relationship between variables via a diagram.

The case study results reveal …

A Hyperbaric Aerodynamic Levitator For Containerless Materials Research, Sydney E. Boland, Stephen K. Wilke, Jonathan A. Scott, Sarah M. Schlossberg, Alex Ivaschenko, Richard J.K. Weber, David W. Lipke

Materials Science and Engineering Faculty Research & Creative Works

A hyperbaric aerodynamic levitator has been developed for containerless materials research at specimen temperatures exceeding 2000 °C and pressures up to 10.3 MPa (1500 psi). This report describes the prototype instrument design and observations of the influence of specimen size, density, pressure, and flow rate on levitation behavior. The effect of pressure on heat transfer was also assessed by studying the heating and cooling behavior of levitated Al2O3 liquids. A threefold increase in the convective heat transfer coefficient was estimated as pressure increased to 10.3 MPa. The results demonstrate that hyperbaric aerodynamic levitation is a promising technique for containerless materials …

The study is grounded in the concept of “Start where the people are” (Nyswander, 1956) which suggests that effective health campaigns that promote prevention strategies to enhance the quality of life for those targeted must be rooted in the prevalent cultural practices and religious values of the receivers of the slogans, themes, and taglines. Health campaigns that superimpose the values of the outsiders promoted as universalized solutions have limited effectiveness.

Threading Memory: Performing Animacy In Text, Memorial, And Travel, Alex Keith Davenport

Dissertations

This dissertation explores the process of creating and touring a community-sourced memorial quilt for the anti-mountaintop removal activist Julia “Judy” Bonds, who died in 2011. As a practice, the project positions memorialization as a possible framework for social movements to utilize when faced with loss that allows for actions that honor members of the movement while still engaging in consciousness raising and organizing efforts. From a theoretical standpoint, the practice of memorialization—especially when it is intentionally designed to align with the practices/legacy of the person(s) being remembered—is also considered through an object oriented ontology perspective, providing insight into the affective …

Cultivating Community: Investigating Performances Of Community In Ecovillage Settlements, Alex Lockwood

Dissertations

This dissertation considers the subject of ecovillages, intentional ecologically-oriented sustainable communities developed in the U.S., and the different understandings of community involvement, structure, and challenges that members of these communities confront in their efforts at managing these time and labor-intensive settlements. Informed by the work of performance ethnographers and critical phenomenologists, I consider twelve interviews I conducted on-site and electronically with people living in ecovillage settlements. Taking these interviews and my own observations from on-site visits to two ecovillages as entry points, I conducted a phenomenological analysis informed by a critical phenomenological ethos of these accounts, highlighting five motifs that …

Community In The Cell: Queer Women’S Space And Place In New Orleans, Jordan Hammon, Jordan Hammon

LSU New Orleans Theses and Dissertations

This thesis examines queer women’s history and space/places of community in New Orleans using spatial analysis and feminist theory to fill the silences. The Special Citizens Committee for the Vieux Carré laid the foundation for regulating queer women and transmasculine people starting in the 1950s. Even after the committee ended, New Orleans Police Department and the Vice Squad had the power to invade and harass places of community for queer women and transmasculine people. Despite this hostility, queer women and transmasculine people resisted and made a place for themselves in New Orleans. As a result of their persistence through visibility …

Improved Marginal Likelihood Estimation Via Power Posteriors And Importance Sampling, Yong Li, Nianling Wang, Jun Yu

Research Collection School Of Economics

Power posteriors have become popular in estimating the marginal likelihood of a Bayesian model. A power posterior is referred to as the posterior distribution that is proportional to the likelihood raised to a power b∈[0,1]. Important power-posterior-based algorithms include thermodynamic integration (TI) of Friel and Pettitt (2008) and steppingstone sampling (SS) of Xie et al. (2011). In this paper, it is shown that the Bernstein–von Mises (BvM) theorem holds for power posteriors under regularity conditions. Due to the BvM theorem, power posteriors, when adjusted by the square root of the auxiliary constant, have the same limit distribution as the original …
