Examining Framing Of Local And National Media Coverage Of Sandy Hook And Robb Elementary School Shootings, Gabrielle L. Debruler

LSU Master's Theses

There have been over 350 K-12 school shootings since the shootings at Columbine High School in 1999 (Cox et al., 2023). Thousands of journalists cover these attacks each in their own way with unique motives. This information goes to the public, and it is up to that person how they want to consume the story and view the shooting. National and local journalists tend to cover school shootings quite differently throughout time with unique frames. The shootings at Sandy Hook Elementary and Robb Elementary Schools illustrate this framing distinctively.

Through a qualitative study of national and local coverage of the …

Identifying Key Language Research Priorities In Autistic Children According To Parents, Taylor Hale

LSU Master's Theses

The lack of involvement of the autistic community and its stakeholders in autism research has led to a call to action. At present, autism researchers have limited knowledge about stakeholders’ priorities for research. The current study aimed to bridge the disconnect between the extant autism research and the recent neurodiversity movement by surveying key stakeholders – parents of autistic children – on their perspectives on autism research that focuses on language. Twenty-six parents of autistic children completed an online survey on their views on autism language research with an option to participate in a follow-up interview. Six parents participated in …

Exploring The Effects Of Individuals’ Perceived Prototypicality Within A Fandom, Keely Diebold

LSU Master's Theses

Passionate fandoms centered on popular film and television series can elicit large-scale positive fan activity. At the same time, however, negative consequences can arise as factions or subsets of members with varying opinions arise within fandoms. One possible explanation for this phenomenon is varied levels among fandom members of how prototypical they view themselves within the context of that fandom. Research on social groups, however, has historically looked exclusively at perceptions of others' prototypicality and not of the self. Drawing on theories of social identity (SIT) and self-categorization (SCT), this project serves to bridge this research gap by exploring to …

Emily Somebody: A Chamber Opera In Three Acts, Rodrigo Afonso Salles Camargo

LSU Master's Theses

Emily Somebody is a chamber opera in three acts that tells the story of the friendship between the American poet Emily Dickinson and the man that would become her first editor, Mr. Thomas Higginson. This story, for me, is ultimately about a poet (or an artist) in the process of finding not only her own voice but also discovering what poetry and art mean to her, in the most genuine way, and standing up for these beliefs and values. All the lyrics used in this work are from Emily Dickinson’s poems and letters exchanged between her and Mr. Thomas Higginson.

Gulf Sturgeon Mesohabitat Use And Movement In The Lower Pearl River Louisiana-Mississippi, Amanda Popovich

LSU Master's Theses

After spring migrations to natal rivers Gulf Sturgeon Acipenser oxyrinchus desotoi reside in freshwater holding areas prior to fall emigrations to nearby estuaries. Limited published information on the physical habitat characteristics of these holding areas is available, especially for juvenile fish in the western portion of the Gulf Sturgeon’s distribution. To further investigate freshwater occupancy and movement patterns, 32 acoustic receivers were deployed from late April to October of 2021 and 2022 in 1600-m reaches distributed throughout the lower Pearl River, Louisiana-Mississippi, the westernmost river within their distribution. Generalized linear mixed models and multi-state models were used to determine what …

Quantifying Mud Settling Velocity As A Function Of Turbulence And Salinity In A Deltaic Estuary, Michael W. Mcdonell

LSU Master's Theses

Mud settling velocity is controlled by flocculation, which in turn strongly depends on turbulence and on the chemistry and biology of the water-sediment mixture. As a result, mud settling velocity can be poorly constrained in coastal areas and vary in space and time by orders of magnitude. Here we quantified mud settling velocity in Barataria Basin, a deltaic estuary in Louisiana (USA), using three independent methods: eddy covariance (one station for 200 days), floc cameras (4 stations at one time), and Rouse profile inversion (14 stations, replicated 10-30 times each). Eddy covariance indicates that settling velocity increases with turbulence, at …

Effect Of Furosemide Administration On Plasma Analytes And Urine Enzyme Excretion In Two Reptilian Species, Kathryn Metcalf

LSU Master's Theses

Renal disease is a common ailment of captive reptiles that is often closely linked to chronic, subclinical states of dehydration. Currently, the diagnosis of renal disease in reptiles is poorly characterized and often relies on invasive diagnostic techniques (e.g., renal biopsy) for definitive diagnosis. A potential outlet for the further characterization of renal dysfunction in reptiles is the induction of dehydration by furosemide therapy. Furosemide is a loop diuretic that is commonly used in mammalian patients for the treatment of congestive heart failure. The utility of furosemide in reptiles is poorly characterized, however, both experimental and clinical utility of this …

The Possibility Of Relationships With Others, Joshua Severud

LSU Master's Theses

Levinas offers a rich philosophical insight into the kind of responsibility and ethics that we must have for the Other. This involves a certain conception of what it means to be hospitable which turns out to be impossible. In order to talk about how this impossible relationship can occur, I use Heidegger’s description of the existential Being-with structure and Derrida’s conception of the event in order to make sense of how this Levinasian relationship can possibly exist in spite of—or thanks to—its impossibility.

Deposition, Material Characterization, And Mechanical Testing Of Cr Containing Diamond-Like Carbon Films, Nicholas Anderson

LSU Master's Theses

A series of amorphous hydrogenated chromium containing diamond-like carbon films were deposited on 316 stainless steel substrates with a chromium interlayer through inductively coupled plasma assisted direct current magnetron sputtering. Details on the deposition process of these films are discussed. The film is characterized using scanning electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, energy dispersive spectroscopy, and transmission electron microscopy. The coating hardness and indentation modulus is measured by instrumented nanoindentation. The coefficient of friction and the upper bound of the coating wear coefficient is measured using the pin-on-disk method. The fracture toughness of the diamond-like carbon film and a …

Exploring The Interactive, Linguistic, And Conceptual Dimensions Of Parent Input And Their Role In Children's Pragmatic Development, Nickolas T. Day

LSU Master's Theses

The development of children’s pragmatic language, which can be defined as conversational competence in social contexts, has been attributed to variation in the language they hear in their environment. When studying the impact language input has on pragmatic development, it is important for clinicians and linguists to measure both the quantity and quality of this language input. Measures of quality, however, are much more relevant when studying the development of pragmatic language, as discussed in Zhang (2020) and Hirsh-Pasek et al. (2015). Rowe and Snow (2016) discussed three dimensions of language quality: interactive, linguistic and conceptual. There is a current …

A New Test Of The News: An Examination Of The New York Times And Cnn Coverage Of The War In Ukraine, Hannah Ross

LSU Master's Theses

Russia launched a military invasion of Ukraine on 24 February 2022, setting off Europe’s largest war since World War II. The war captured the attention of American news organizations, which gave the conflict unprecedented levels of coverage. This thesis tested the coverage of the war in Ukraine by two major American news outlets: The New York Times and CNN. This study used qualitative content analysis to examine the top four front-page stories of the Times and CNN Newsroom show. Two timeframes were used to analyze these materials: February 24, 2022, to March 9, 2022, and September 17, 2022, to September …

Evaluating Form And Function Of Groundcovers And Their Environmental Impacts In Louisiana Landscapes, Thomas Maxwell Mckeown

LSU Master's Theses

Increasing environmental concerns are encouraging the adoption of sustainable landscapes that have environmental, social, and financial benefits. Ornamental groundcover systems are touted as sustainable landscape features due to the associated decreased demand of water, fertilizer, pesticide, and maintenance; however, limited research exists on soil property effects, planting density, weed density, or consumer preferences of groundcovers. This study was aimed to gain a more thorough understanding of ornamental groundcovers systems and their environmental impacts. The effects of groundcover growth habit (matting; bunching) and irrigation delivery (micro spray; overhead) on soil temperature, volumetric water content (VWC), and electric conductivity (EC) along with …

Snow Distribution And Influence In Taylor Valley, Antarctica, Using Remote Sensing, Katherine Mcnulty, Peter Doran, Mark Salvatore, Suniti Karunatillake

LSU Master's Theses

The McMurdo Dry Valleys is the largest ice-free area in Antarctica, but seasonal snow covers the valley floors sporadically throughout the year. In this study, a model to estimate areal snow coverage from satellite imagery was created. An area-volume model was created to estimate the amount of snow water equivalent (SWE) from the snow area extracted from the imagery. Snow cover influences the total albedo, the hydrologic budget, and the soil moisture and soil temperature in Taylor Valley (TV). Quantifying snow precipitation in TV is challenging because snow redistributes with winds, sublimates, or melts within a short period. Previous estimates …

News(?)Papers: A Typology Of Fake News, 1880-1920, Olivia G. Romaguera

LSU Master's Theses

“Fake news” is a malleable concept. It can be beaten and reshaped to fit many different contexts. One widely accepted definition of fake news is false information purporting itself to be factual. Another is information that is factual but called “fake” in order to discredit it. Concern over the spread of fake news increased in recent years. But preoccupation with what is happening today has left a gap in our understanding of the phenomenon, specifically its roots in the past. “Fake news” was present when news technology was relatively primitive; it is not essentially a function of such modern advancements …

The Nature And Role Of Phenomenology In Hegel And Heidegger, Gabriel W. Connor

LSU Master's Theses

In this work I compare Hegel and Heidegger’s conception of phenomenology and its role in their thinking. Though these two thinkers are not often examined from this angle, and though there is controversy surrounding just how phenomenological each thinker might actually be, an examination of the two thinkers in this regard serves to identify interesting connections between Hegel and Heidegger while also raising questions about phenomenology in general. In short, I seek to establish that phenomenology in both Hegel and Heidegger is not adequately understood unless it is placed in the context of each thinker’s conception of human freedom along …

Natural Lights & Natural Rights: The Problem Of The New Classical Natural Law Theory, Charles Neville Cacciatore

LSU Master's Theses

The present work examines the natural law jurisprudence of John Finnis. It argues that Finnis’s teaching is a genuinely new natural law theory. Finnis’s jurisprudence is not a re- presentation of the jurisprudence of St. Thomas Aquinas because its central element—a doctrine of natural rights—is a departure from Aquinas’s natural law teaching. In support of these claims, the present work relies upon the scholarship of Ernest L. Fortin, A.A. Following Fr. Fortin, it presents an understanding of the natural law that endorses a clear distinction between natural right and natural rights—between premodern political philosophy and modern political philosophy.

Evaluating Attitudes Toward Non-Formal Science Education Programs Among High School Science Teachers In Southeast Louisiana, Heather Egger

LSU Master's Theses

Abstract

The Louisiana Department of Education (LDOE) has begun implementing Louisiana Student Standards for Science (LSSS), as well as developing high school science certification programs. The LDOE recognizes that teaching science using three-dimensional learning methods and phenomena based inquiry learning will be a challenge that would be addressed in part by partnerships between formal science teachers and nonformal science education programs. However, limited available information on this topic shows that utilization of nonformal science education opportunities by science educators has declined and, in some instances, have been relegated to unstructured “fun” outings to reward students, often after the final quarter …

Phonic Faces As A Method For Improving Decoding For Children With Persistent Decoding Deficits, Chantal H Farag Hanna

LSU Master's Theses

Background: Decoding is a foundational skill for reading, contributing to both reading fluency and comprehension (Lyon et al., 2003). Visual enhancements of alphabetic letters such as shaping letters to resemble words beginning with that sound (e.g., “f” drawn as a flower) (Handler & Fierson, 2011) and associating photographs of lips producing the sounds (Lindamood & Lindamood, 1998) have been shown to improve decoding skills. This study investigated whether a more direct pictured association using faces with alphabet letters placed in the mouth to cue speech sounds, termed Phonic Faces (Norris,2001), would enable students with persistent decoding impairment to acquire orthographic …

Louisiana Resident Perceptions On Invasive Aquatic Plant Species And Their Management, Anna Ribbeck

LSU Master's Theses

Determining the public perception of invasive species in Louisiana is an important tool to help shape and develop future management decisions, educational material and ultimately public policy. Therefore, the primary purpose of this study was to determine the perceptions of adult Louisiana residents regarding invasive aquatic plant species and their management. An online survey was used to collect data on registered Louisiana residential boaters’ perceptions towards invasive aquatic plants and their management. A postcard with a quick response code leading to the survey was mailed to 6,000 randomly selected Louisiana registered residential boaters. Of the 230 Louisiana registered boaters that …

The Function Of Transport Protein Mfl1 In Arabidopsis Thaliana, Joseph Qian

LSU Master's Theses

Photosynthesis serves as the primary process for plants to synthesize ATP and sugar molecules, however, this reaction requires many cofactors such as heme, plastoquinone, and iron-sulfur clusters to assist in energy gathering and electron transfer steps. Many of these require trace metals, such as iron, to cross across the chloroplast membranes and be incorporated into proteins and other organic molecules to form useable cofactors. The light-independent reactions of photosynthesis are also inefficient, with up to 25% of the photosynthetic energy wasted to metabolize the toxic waste product glycolate. The cellular logistics of both photorespiration and iron transport have been studied, …

Recombinant Dna Vaccine Design As A Potential Strategy Against Bovine Foot And Mouth Disease Virus (Fmdv), Taylor Haynie

LSU Master's Theses

Foot-and-mouth disease virus (FMDV) is the causative agent for foot-and-mouth disease (FMD) that infects primarily cloven-hoofed animals, the majority of which are domesticated cattle and other important livestock. FMD is highly transmissible and found in all secretions and excretions of infected animals. North America, Europe, and Australia have successfully eradicated the virus with the help of a well-defined fiscal infrastructure and access to successful control measures. Less developed regions, including many Asian and African countries, have maintained an endemic status for decades. African territories are of particular concern because of the indigenous African Buffalo population that serves as an important …

Cable Decoupling And Cable-Based Stiffening Of Continuum Robots, Parsa Molaei

LSU Master's Theses

Cable-driven continuum robots, which are robots with a continuously flexible backbone and no identifiable joints that are actuated by cables, have shown great potential for many applications in unstructured, uncertain environments. However, the standard design for a cable-driven continuum robot segment, which bends a continuous backbone along a circular arc, has many compliant modes of deformation which are uncontrolled, and which may result in buckling or other undesirable behaviors if not ameliorated. In this study, a detailed approach for using additional cables to selectively stiffen planar cable-driven robots without substantial coupling to the actuating cables is investigated. A mechanics-based model …

Improved Selectivity And Stability In Methane Dry Reforming By Atomic Layer Deposition Onto Ni-Ceo2-Zro2/Al2o3 Catalysts, Jonathan Lucas

LSU Master's Theses

The use of Ni in the dry reforming of methane (DRM) has been widely studied as a replacement for noble metal catalysts (Pt, Pd, Rh) due to Ni’s low cost compared to noble metals, its abundance, and the fact that its DRM activity is near that of noble metal catalysts. However, Ni has been shown to deactivate quickly under DRM conditions. Rare earth oxides such as CeO₂, or as CeO₂-ZrO₂ (CZO) are supports that improve both the activity and stability of Ni DRM systems due to their redox activity. However, this same activity is thought …

The Perceptions, Experiences, And Stories Of Tied-Migrant Music Educators: How The Personal And Professional Blend, Rachel K. Broyles

LSU Master's Theses

Centering around the purpose of examining the lived experiences and perspectives of self-identified tied-migrant music educators and how the transitory aspects of their personal lives impact their professional careers, this phenomenological case study discusses the findings of both a review of literature and completed original research utilizing two participants who are tied-migrant spouses in the music education field and examine their stories. For this study, tied- migrant spouses are defined as persons who are married to individuals who frequently relocate due to their professional occupation (Mincer, 1978). Participants include tied-migrant military spouses and tied-migrant civilian spouses.

Specific research questions include: …

Consumer Shift: Examining Female Generation Y Consumers’ Activewear Consumption, Lauren Laporte

LSU Master's Theses

The onset of the Covid-19 pandemic resulted in a change to standard consumption patterns as consumers began prioritizing health and wellness, working remotely, and made a switch from material-based consumption practices to an experiential-value-based consumption mindset. Additionally, Covid-19 brought economic downturns, loss of jobs, and supply chain issues. Consequently, the activewear market demonstrated unclear results making it necessary to understand trends within the activewear market while also understanding consumer motivations to wear or not to wear activewear during these societal shifts. This research paper aims it’s focus on female members of Generation Y, a popular and growing market for activewear. …

Examining Real-Time Variations In Interpersonal Hopelessness And Suicidal Ideation Using Ecological Momentary Assessment, Jessica Lauren Gerner

LSU Master's Theses

The Interpersonal Theory of Suicide (ITS; Van Orden et al., 2010) hypothesizes that suicidal ideation (SI) arises from the simultaneous presence of thwarted belongingness (TB) and perceived burdensomeness (PB). For SI to intensify to suicidal desire, hopelessness about the changes in TB and PB must be present (Van Orden et al, 2010). Recent research on the ITS has moved away from a general measure of hopelessness, instead focusing on hopelessness specific to the interpersonal constructs of TB and PB (Tucker et al., 2018). This construct, referred to as interpersonal hopelessness (IH), is further broken down into two correlated but distinct …

The Influence Of Child Maltreatment In The Manifestation Of Anxiety And Depressive Symptoms At The Age 18, Maria J. Velasquez

LSU Master's Theses

Child maltreatment affects thousands of children and adolescents every year. This phenomenon is multidimensional, meaning there are different subtypes (i.e., physical abuse, sexual abuse, emotional abuse, and neglect) known to predict various mental health issues, including depression and anxiety. While previous research has investigated mental health outcomes in maltreated youth, results may vary based on the dimensions of abuse considered. This study aims to expand on previous literature to examine how a history of child maltreatment subtypes influences the manifestation of anxiety and depressive symptoms in youth at age 18. The current study uses secondary data analysis of the Longitudinal …

Motivators And Preferences Of Route Diversion During Roadway Incidents, Grace Cole

LSU Master's Theses

When confronted with congestion and delay, drivers often divert their route. Depending on factors like purpose, urgency, destination, route alternatives, type of disruption, and mode options, common diversionary options can range from changing departure time, route, and mode to canceling a trip altogether. One of the foundational building blocks of travel forecasting is traffic assignment, which is used to distribute trips over a network using complex algorithms to aggregately represent the desire of drivers to minimize travel time.

While these assignment models are backed by decades of research and observational experience, they are also limited by the fact that they …

Evaluating Sensory Quality, Willingness To Try, Risk And Product Appropriateness Of Seafood Byproducts, Silvia Jessenia Murillo Miguez

LSU Master's Theses

Valorization of food wastes/byproducts has become a major subject of research to increase sustainability of the global food supply chain. Seafood industries generate a substantial quantity of byproducts. An online survey was used to evaluate Willingness-to-try (WTT), the effect of a Consumer Safety Statement (CSS) on WTT, perceived risks and product appropriateness associated with seafood byproducts in food as influenced by gender and race. Based on the finding from this survey, a clean label catfish bone powder (CBP) was developed and used for breaded catfish sticks which were evaluated for sensory liking, emotional profile, and purchase intent. Previous consumers of …
