Age And Growth Of Blackfin Tuna (Thunnus Atlanticus) In The Gulf Of Mexico, Elsa M. Gutierrez

LSU Master's Theses

Tunas are highly migratory species that are ecologically and economically important components of oceanic ecosystems worldwide. Unfortunately, life history information for the smallest true tuna (genus: Thunnus), blackfin tuna Thunnus atlanticus, is scarce despite the fact that it is the most abundant tuna found throughout much of the western Atlantic. In this study an otolith-based aging approach was used to evaluate age and growth relationships, examine sexual dimorphism in growth, and derive mortality estimates for blackfin tuna in the Gulf of Mexico. Age and growth relationships were evaluated using two models commonly applied to age-at-length data for tunas: the …

Examining The Relationship Between Functionally Assessed Parental Behavior And Child Anxiety, Allison Smith

LSU Master's Theses

Etiological theories of child anxiety suggest an interaction of multiple factors that lead to the development and maintenance of child anxiety. Environmental influence, specifically that involving the family or parent, has been a target area of study for decades. Additionally, functional assessment of behavior indicates that certain behaviors may be maintained primarily by specific functions. Functional assessment has been successful at identifying functions of problematic behavior and planning treatment accordingly. However, in the realm of child internalizing disorders, research has not utilized functional assessment in this way. Acknowledging the impact of parental behavior on child anxiety as well as the …

Analysis Of Briquetage (Brine-Boiling Pots) At Paynes Creek Salt Works: Implications For Classic Maya Salt Production, Rianna Bowen

LSU Master's Theses

Abstract

The Classic Maya period (A.D. 300-900) is characterized by large urban centers, distinct material culture, and long-distance trade of both utilitarian and elite goods. The rise in population during this time created a necessity for essential, everyday goods, to move along these trade routes; one of which was salt. Additionally, much of the production of utilitarian goods was occurring outside of urban centers and political control at smaller, specialized production locales. The Paynes Creek Salt Works in southern Belize was one of these specialized production locales. The number of salt works located in the Punta Ycacos lagoon suggests salt …

Examination Of Pre-Emergence Control Of Johnsongrass In Sugarcane Seedlings, Carleton Baucum

LSU Master's Theses

Sugarcane is susceptible to many diseases and insect pests; therefore, to maintain high sugar yield new varieties must be developed. Producing new varieties contributes to the overall crop success through enhanced yield, insect and/or disease resistance, cold tolerance, and ratooning ability. However, unlike conventional sugarcane, which is vegetatively propagated, new sugarcane varieties are produced from true seed. These seedlings are more susceptible to herbicidal injury and weed competition than conventional sugarcane. For sugarcane seedlings to succeed, weeds must be controlled therefore, the most effective herbicide program with regards to seedling safety must be implemented. The objectives of this research were …

Anticipating Stochastic Integrals And Related Linear Stochastic Differential Equations, Sudip Sinha

LSU Doctoral Dissertations

Itô’s stochastic calculus revolutionized the field of stochastic analysis and has found numerous applications in a wide variety of disciplines. Itô’s theory, even though quite general, cannot handle anticipating stochastic processes as integrands. There have been considerable efforts within the mathematical community to extend Itô’s calculus to account for anticipation. The Ayed–Kuo integral — introduced in 2008 — is one of the most recent developments. It is arguably the most accessible among the theories extending Itô’s calculus — relying solely on probabilistic methods. In this dissertation, we look at the recent advances in this area, highlighting our contributions. First, we …

Improving Memory Forensics Capabilities On Apple M1 Computers, Raphaela Santos Mettig Rocha

LSU Master's Theses

Malware threats are rapidly evolving to use more sophisticated attacks. By abusing rich application APIs such as Objective-C’s, they are able to gather information about user activity, launch background processes without the user’s knowledge as well as perform other malicious activities. In some cases, memory forensics is the only way to recover artifacts related to this malicious activity, as is the case with memory-only execution. The introduction of the Rosetta 2 on the Apple M1 introduces a completely new attack surface by allowing binaries of both Intel x86 64 and ARM64 architecture to run in userland. For this reason it …

Teachers' And Students' Perceptions Of Goal Orientation Theory In Secondary Instrumental Music Classrooms: A Case Study, Carlye Mcgregor

LSU Master's Theses

Goal orientation theory (Ames, 1992; Blumenfeld, 1992) is a cognitive theory that identifies how goals affect motivation in students. The benefits of mastery goal orientation — aspects of instruction which support the connection between effort and achievement — on student motivation and participation have been well-documented. Researchers (Ames & Archer, 1988; Patrick, et al., 2001) found students can pick up on goal cues and identify traits of each theory apparent in their classroom. Teachers communicate their values through goal structures, and student motivation can be improved by consistent goal structures, or negatively affected by misaligned goal structures (Ames & Archer, …

Implicit Bias In Speech-Language Pathology Students, Skyller Castello

LSU Master's Theses

Implicit racial biases have been documented across a variety of allied health professions. A systematic review conducted by FitzGerald and Hurst (2017) of implicit bias in healthcare professionals found that 20 out of 25 studies examined displayed bias against BIPOC in diagnosis, treatment recommendations, and other aspects of the medical care they received. A literature review completed by Hall et al. (2015) found similar results, stating that 9 of the 15 studies examined identified bias against Black clients. One allied healthcare profession, speech-language pathology, interacts with a diverse clientele in a clinical environment and yet have been excluded from much …

"Man Of The Machine": Ernst Jünger's Philosophy Of Technology And The Spiritualization Of The ��������������������������������, Andrea L. Wisniewski

LSU Master's Theses

This thesis examines how conservative German war veterans, in particular author Ernst Jünger, granted meaning to the First World War by affirming the technological encounter. Instead of succumbing to the feelings of powerlessness and inferiority engendered by the domination of machinery on the Front, Jünger and other conservative veterans elevated the Materialschlacht into a spiritual event, a battle between the spirit and the material in which the human spirit emerged victorious. Strengthened by their confrontation with the machine, humans gained the spiritual skills which would enable them to master the machine and, therefore, meet the demands of the technological world. …

Two major forms of fuel minimization are studied. First, the eco-driving problem is solved for a …

A Street-Based Simulation Approach To Evaluating Crime Theories And Deterrence Efficacy In Baton Rouge, Louisiana, Shaun Edward Williams

LSU Doctoral Dissertations

Criminology of place and deterrence strategy evaluations share separate yet similar paths towards incorporating microgeographic units of analysis within deterrence strategies. These transitions have been underway since Weisburd’s 2015 criminology of place work and Kennedy’s 1997 Ceasefire publication for deterrence strategy evaluation. Rather than purely theoretical or practical challenges serving as agents of change, scale appropriateness can arguably be pinpointed as the foundation for change in both areas. Microplace offers improved insight into the study of crime and place dominated by areal designs. This status quo has hampered evaluation but has not slowed the flow of resources to support strategy …

Practical Considerations And Applications For Autonomous Robot Swarms, Rory Alan Hector

LSU Doctoral Dissertations

In recent years, the study of autonomous entities such as unmanned vehicles has begun to revolutionize both military and civilian devices. One important research focus of autonomous entities has been coordination problems for autonomous robot swarms. Traditionally, robot models are used for algorithms that account for the minimum specifications needed to operate the swarm. However, these theoretical models also gloss over important practical details. Some of these details, such as time, have been considered before (as epochs of execution). In this dissertation, we examine these details in the context of several problems and introduce new performance measures to capture practical …

Effects Of Engagements And Presentation Order In Informal Science Presentations, William Henry Katzman

LSU Doctoral Dissertations

Science museums conduct presentations for their audiences to attract and educate visitors, yet research on presentations has primarily concentrated on whether individual presentations were effective. This mixed-methods, quasi-experimental study looks at how the presenter’s mental and physical engagements within a presentation affects audience members by altering sociocultural context of the presentation.

Physical engagements involve asking audience members to physically participate, while mental engagements involved asking audience members to make predictions prior to observing a demonstration. Audiences were given presentations containing: 1) Both mental and physical engagements, 2) Physical engagements only, 3) Mental engagements only or 4) No engagements (control).

Colonial Myths: The Conquest Of Cabeza De Vaca, Willie Hurst

LSU Master's Theses

This thesis examines the relaciónes (report) Naufragios (1542) and Comentarios (1555) with the intention of expanding upon the ample publications already existent on Cabeza de Vaca. With this thesis I offer a contrasting reading and reexamination of both of Cabeza de Vaca’s works. I argue that a number of the scholarly publications on Cabeza de Vaca fail to understand, define, and explore the identity and goals of Cabeza de Vaca as his own unique version of a conqueror which ultimately leads to a misunderstanding and misinterpretation of the texts. After an initial chapter discussing how Cabeza de Vaca never underwent …

Sediment Buffering And Recycling On An Annual To Centennial Scale Along The Mississippi River, Nikki E. Neubeck

LSU Master's Theses

Although the Mississippi River and its tributaries have been investigated for many years, the alteration of the river through dams, levees, and diversions has affected how sediment is transported from source to sink (>10³ y). Previous provenance research using detrital zircon U-Pb dating indicates a slow transport time from source-to-sink, but recent anthropogenic alterations of the river may potentially diminish the transportation time of heavy minerals due to an increase in flow efficiency. The objective of this study is to analyze the degree of buffering and recycling of Mississippi River sediment over a range of short time scales, …

Corporate Website Disclosures And Financial Reporting Quality, Nicholas Mueller

LSU Doctoral Dissertations

This study examines the relationship between corporate website disclosures and financial reporting quality. Using a sample of the S&P 500 and S&P 400 firms, a voluntary website disclosure score is created by identifying specific website disclosures. After controlling for website disclosure requirements imposed by U.S. stock exchanges, the results indicate that firms with greater website disclosures are associated with lower abnormal accruals and differential persistence of cash flows and operating accruals. Additionally, using the Chen, Miao, and Shevlin (2015) measures for disaggregation quality of financial statement items, the results suggest that the association between financial reporting quality and website disclosures …
