Librarians’ Use Of Instructional Design Methods In Creating Information Literacy Instruction, Michael W. Wilson

Theses and Dissertations

The purpose of this sequential explanatory mixed methods study was to determine whether instruction librarians in the United States and Canada were using instructional design (ID) methods, and to identify potential explanations for their adoption or rejection of those methods. The theory of planned behavior (Ajzen, 1985) served as the theoretical framework for the study. Research questions examined the relationship between respondents’ reported use of ID methods and the following factors: (a) behavioral, normative, and control beliefs, (b) demographic factors, and (c) professional identity as teachers. A survey adapted from Ajjan and Hartshorne (2008) and from Julien and Genuis (2011) …

Relative Resistance To Breaking Of Pinus Taeda L. And Pinus Palustris, Cory Glenn Garms

LSU Master's Theses

Patterns from hurricane damage give an indication that longleaf pine (Pinus palustris) is more windfirm than loblolly pine (Pinus taeda). Tree windfirmess has been attributed to many factors including species and material properties like wood strength and stiffness. Because longleaf pine wood is stronger and stiffer than loblolly pine wood, this study used static winching methodology to see if these properties account for differences in windfirmness by measuring bending force required to break stems (MMAX). Stress-strain diagrams were constructed for pulled trees to explore how they behave under increasing loads. Based on these diagrams, it appears that living trees can …

Social Media Network Data Mining And Optimization, Neha Clare Jose

LSU Master's Theses

Many small social aid organizations could benefit from collaborating with other organizations on common causes, but may not have the necessary social relationships. We present a framework for a recommender system for the Louisiana Poverty Initiative that identifies member organizations with common causes and aims to forge connections between these organizations. Our framework employs a combination of graph and text analyses of the organizations' Facebook pages. We use NodeXL, a plugin to Microsoft Excel, to download the Facebook graph and to interface with SNAP, the Stanford Network Analysis Platform, for calculating network measurements.

The Effects Of Carbon Nanotubes On Cells In A Synthetic Oxygen Carrier Enriched Alginate Scaffold, Joshua Paul Tate

LSU Master's Theses

Abstract Huge progress has been made in the development of three dimensionally printed tissue structures. With the use of cells, three dimensional printers, and CAD drawing software, donor identical structures can be fabricated. However, cell scaffolds currently lack significant mechanical integrity which can result in reduced cellular survival, attachment, and nutrient delivery. For this reason, multiple strategies have been developed to increase and improve mechanical stability within engineered constructs without having to sacrifice cell viability. The hypothesis of this paper was that incorporating Perfluorotributylamine (PFTBA), a greenhouse gas, with single walled carbon nanotubes (SWCNT), a allotrope of carbon with a …

The Role Of Nadph Oxidase 2 (Nox2) In High-Fat Diet-Induced Adiposopathy And Brain Dysfunction In A Mouse Model, Jennifer Kathleen Pepping

LSU Master's Theses

Obesity can have numerous detrimental consequences, namely metabolic syndrome, type 2 diabetes, cardiovascular disease, cancer, and Alzheimer’s disease. The pathogenesis and physiologic consequences of obesity are unknown, but they are often associated with increased inflammation and oxidative stress in both the body and in the brain. One factor that has been implicated in causing inflammation associated with a high fat diet is the enzyme NADPH oxidase, or NOX, specifically the subunit NOX2. Two studies were performed in order to assess the effects of a high fat diet in combination with a universal NOX2 deficiency and a NOX2 deficiency targeted to …

Developing A Mathematically Informed Approach To Musical Narrative Through The Analysis Of Three Twentieth-Century Monophonic Woodwind Works, Wesley James Bradford

LSU Doctoral Dissertations

This project applies mathematically informed narrative to monophonic music in the twentieth century, with a focus on three works for solo woodwinds: Debussy’s Syrinx (flute), Stravinsky’s Three Pieces for Clarinet, and Britten’s “Bacchus” from Six Metamorphoses after Ovid, Op. 49 (oboe). This music poses difficulties for traditional analytical methods due to a lack of explicit harmonies and unusual pitch language that is neither functionally tonal nor serially atonal. Additionally, these pieces present a variety of challenges due to differences in length, number of movements, and presence or absence of programmatic elements. Therefore, nontraditional methods could be beneficial for understanding these …

Coastal Flood Risk In A Changing Climate Along The Northern Gulf Of Mexico, Matthew Vernon Bilskie

LSU Doctoral Dissertations

Coastal regions around the world are experiencing increased vulnerability from natural and manmade disasters.

Strengthening Shear Deficient Thin-Walled Steel Beams By Bonding Pultruded Gfrp Sections, Tuna Ulger

LSU Doctoral Dissertations

Rehabilitation and retrofitting methods offer economical and feasible alternatives for upgrading aged and deficient structures. Structural strengthening using Fiber Reinforced Polymer (FRP) composites have been widely investigated by researchers and used in field applications. The main advantage of FRP composites is the superior mechanical properties they offer over traditional structural materials. One novel alternative of these retrofitting methods was developed at Louisiana State University and called “Strengthening-by-Stiffening” (SBS). In SBS, the external strengthening of shear deficient thin-walled steel structures is achieved by bonding pultruded FRP sections to buckling prone web panels. Contrary to the commonly used uniaxial tension resistance of …

Buying In And Selling Out: African-American Ownership Of Record Labels In The Twentieth Century, Stuart Lucas Tully

LSU Doctoral Dissertations

Throughout the twentieth century, African-American owned record labels seemingly served as embodiments of entrepreneurialism’s capacity to generate social uplift for the race as well as wealth. However, an examination of Black Swan Records, Motown, and Def Jam Records, demonstrates how this assertion is undermined by the actions of their owners. Harry Pace founded Black Swan Records in 1921 not only to showcase black artists, but also prove the African-American audience was capable of appreciating classical music and other high culture. However, faced with financial pressures, Pace expanded the genres recorded on Black Swan to include jazz and other genres deemed …

Vegetation Influences Microbial Community Structure And Methane Emissions In Southeastern Louisiana Wetlands, Anthony Jason Rietl

LSU Doctoral Dissertations

Methane has a warming potential 28 times that of carbon dioxide and has been increasing in the Earth’s atmosphere since 1750. An understanding of the dynamics of methane emissions from natural sources is becoming increasingly important as we may need to mitigate emissions from these sources in the future to help reduce the effects of climate change. Wetlands are the single largest natural source of methane; however, little attention has been given to how plant species, biota, and interactions between above and belowground communities and microbial communities may affect methane emissions. First, microbial community structure and function was assessed for …

Circumstellar Dust Shells: Clues To The Evolution Of R Coronae Borealis Stars, Edward Joseph Montiel

LSU Doctoral Dissertations

The existence of extended, cold dust envelopes surrounding R Coronae Borealis (RCB) stars has been known about for over 30 years. RCB stars are an exotic group of extremely hydrogen-deficient, carbon-rich supergiants that are known for their spectacular declines in brightness (up to 8 mags) at irregular intervals. There are three possible origins of these envelopes: (1) they are fossil planetary nebulae (PNe), indicating that RCB stars formed via a final Helium-shell flash; (2) they are the remnant material from the merger of a CO and a He white dwarf binary, (3) they have been constructed from dust ejection events …

"Miss" Communication: Women Navigating The Crossroads Of The Journalism And Mass Communication Industry And Academia, Aariel Roxanne Charbonnet

LSU Doctoral Dissertations

This qualitative study explores the career transitions of women from the mass communication industry to academia using Schlossberg’s (1984) theory of transition. In addition to the job demands as academics and administrators, mass communication leaders must satisfy the demands of the professional communities their schools serve. This calls for a more practical curriculum with media and communication professionals serving as faculty members. For women, the demands appear to have another layer, as women are leaving the journalism industry earlier than men (Willnat & Weaver, 2014). This begs the following questions: Why are women leaving the industry? What are the experiences …

Caregiver Choice In Autism Intervention: Selections And Influential Factors, Hilary Lynn Adams

LSU Doctoral Dissertations

Although research on Autism Spectrum Disorder (ASD) continues to increase, there is not yet a “cure” for the disorder. There is a lack of consensus regarding most effective treatments, much less an accepted treatment plan or course. Families may feel alone and lost in the treatment decision process. In order to best assist caregivers, psychologists must understand the selections caregivers make, their sources of information, and what influences them in their decision-making process. With this knowledge, clinicians may best effect change in caregiver choice by encouraging informed decision-making and use of empirically-based interventions. Thus, the purpose of the current study …

Roles Of Members Of The Conserved Deda/Tvp38 Membrane Protein Family In Escherichia Coli Drug Resistance And Alkaline Ph Tolerance, Sujeet Kumar

LSU Doctoral Dissertations

The objective of this dissertation is to understand the functions of Escherichia coli YqjA and YghB, which are members of the conserved DedA/Tvp38 membrane protein family. YqjA and YghB are inner membrane (IM) proteins with multiple predicted membrane–spanning domain, sharing 62% amino acid identity and partly overlapping functions. Simultaneous in-frame deletions of these two genes in a strain named BC202 results in various phenotypes including cell division defects, temperature sensitivity, and sensitivity to drugs and alkaline pH. The cell division defect of BC202 is due to the inefficient secretion of periplasmic amidases by the twin arginine transport (Tat) pathway into …

Coastal Ecosystem Resiliency After Major Disturbances, Giovanna Mcclenachan

LSU Doctoral Dissertations

Disturbances are a common occurrence in coastal ecosystems and can provide opportunity for adaptation and renewal in healthy systems; hurricanes bring mineral accretion to a marsh, floods provide a pulse of freshwater and nutrients to estuaries, and fires increase species diversity and abundance in forests. Humans, however, have depleted the resiliency of many coastal systems via top down and bottom up mechanisms, leaving these ecosystems more vulnerable to both natural and anthropogenic disturbances. Louisiana’s wetlands have been modified for centuries via canals, levees, agricultural impoundments, etc., leading to a decreased resiliency to land loss. The Deepwater Horizon (DWH) oil spill …

Effects Of Landscape Fragmentation On Land Loss, Weijia Cheng

LSU Master's Theses

Coastal Louisiana, the seventh largest delta on earth, is one of the most vulnerable coastal areas in the United States of America (USA) because of its land loss problem. Coastal land loss is usually caused by many complicated factors. With the rapid increase in human activities, more studies on land loss have focused on the anthropogenic elements, but less on the pattern of the landscape. It is expected that the type of spatial arrangement, such as high degree of fragmentation, would affect the degree of land erosion. A quantitative evaluation of coastal landscape fragmentation and its influences on land loss …

Glue Sticks And Gaffs: Disassembling The Drag Queening Body, Ray Siebenkittel

LSU Master's Theses

Drag queening men, typically gay men who perform femininities for entertainment, use makeup, padding, injections and other tools to change their bodies for performance. I focus on the backstage activities of drag performers in Baton Rouge, Louisiana, rather than conventional observations from the audience, to explore the negotiation, construction and implications of these bodies, both physically and discursively. Through autoethnographic accounts and participating in my own drag performance, I highlight the often unseen, less frequently discussed aspects of drag queening in order to lessen the distance between the efforts of performers and the stage. Drag queening men’s bodies are a …
