Malware And Memory Forensics On M1 Macs, Charles E. Glass

LSU Master's Theses

As malware continues to evolve, infection mechanisms that can only be seen in memory are increasingly commonplace. These techniques evade traditional forensic analysis, requiring the use of memory forensics. Memory forensics allows for the recovery of historical data created by running malware, including information that it tries to hide. Memory analysis capabilities have lagged behind on Apple's new M1 architecture while the number of malicious programs only grows. To make matters worse, Apple has developed Rosetta 2, the translation layer for running x86_64 binaries on an M1 Mac. As a result, all malware compiled for Intel Macs is theoretically functional …

Cross-Issue Agenda Setting From Racism To Immigration: Spreading Activation Or Group Threat?, Martina Santia

LSU Doctoral Dissertations

Little research to date offers evidence for the “cross-issue agenda setting effect,” that is transfer of salience from media coverage of racism to perceived importance of immigration. Laboratory experiments afford the opportunity to facilitate causal inference in determining whether this cross-issue effect is due to a cognitive mechanism of spreading activation (as conventionally assumed in agenda setting research) or to a cumulative, affective process driven by perceived threat to a certain identity group. Observational data, on the other hand, allow to externally validate the experimental results beyond the constrained settings typical of laboratory experimentation.

This dissertation combines the strengths of …

Outcomes Of Building Parasocial Relationships Betweens Brands And Consumers On Social Media, Emily Ritchart

General Feature Extraction For Process Monitoring Using Transfer Learning Approaches, Wenbo Zhu, Jinhong Zhang, Jose Romagnoli

Faculty Publications

Data-driven methods have been widely used in process monitoring and fault detection areas. Despite that, most of these data-driven approaches are extremely specific, where the developed models can only be applied in the given process with the selected variables. The lack of generalization potentially limits its applications. This work mainly focuses on developing a model with better generalization ability and transferability for process data analytics. We proposed a transitional invariant feature extraction method using convolutional neural networks, which can learn features regardless of the size or sequence of the input. Such an approach allows the transfer learning so that the …

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 …

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. …

The Rise Of Rome, The Fall Of Spain: Classical Reception In Leopoldo Alas, Galdós, And José Díaz Fernández, Meghan E. Hodges

LSU Master's Theses

The turn of the century was a period of rapid change and modernization. Spain, unlike neighboring European nations, was collapsing as an imperial force. The ensuing crisis of national identity fueled existing political tensions from the early nineteenth century which would lead to the Spanish Civil War (1936-1939). This thesis examines various national crises from 1890 and the decade preceding the loss of Spain’s final colonies to 1929 and the decade preceding the Civil War. Both of these periods saw substantial acceleration of modernization and incredible resistance to it. Despite the hyper-presence of modernity within contemporary literary movements, there is …

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 …

Synthesis, Characterization, And Photo-Reactivity Studies On Mo(Vi) Dioxo Complexes For C-H Activation And O-Atom Transfer, Saeed Fosshat

LSU Doctoral Dissertations

Metal oxos are important intermediates in various chemical transformations that include electron transfer, proton-coupled electron transfer (PCET) and and O-atom transfer. Various extent of π-bonding from the oxo ligands to the central metal causes changes in nucleophilicity and overall reactivity of these species. Several factors can influence the electronic structure of the M=O bonds such as central metal oxidation state, geometry, ancillary ligands and spin state of the metal. A general strategy to increase the reactivity of metal oxos is to use electron rich metal centers that are less oxophilic. As a result of this, extensive amount of research has …

Experts’ Views On Issues Affecting Egg Labeling In The United States: A Delphi Study, Rexanna Powers

LSU Doctoral Dissertations

When purchasing food, many consumers have reported they question the ethical and humane treatment of products derived from animals at the point of purchase. To complicate this issue further, many U.S. consumers lack exposure, interaction, and involvement with the agricultural industry. As a result, they have reported a willingness to pay premium prices for meats, dairy, and eggs whose packaging suggests quality welfare practices. Therefore, the purpose of this investigation was three-fold: (1) establish operational definitions for poorly understood poultry industry terms, i.e., cage-free, free-range, pasture-raised, and organic; (2) describe experts’ perceptions of the strengths, weaknesses, opportunities, and threats (SWOT) …

Novel Platforms For Large-Scale Adherent Culture Of Mammalian Cells, Ashkan Yekrangsafakar

LSU Doctoral Dissertations

With recent advances in biotechnology, there is a strong and urgent need for robust platforms to culture mammalian cells on a large scale to produce biopharmaceuticals. To this end, various bioreactors have been developed over the past decades, but their capacity and efficiency are often limited by insufficient mass transfer rate and excessive shear stress. In this work, multiple novel bioreactors for the large-scale adherent culture of anchorage-dependent cells were developed.

Hollow MicroCarriers (HMC) was developed as an alternative solution for the microcarrier-based culture system in a stirred-tank bioreactor. In the conventional microcarrier technique, cells are exposed to the harmful …

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 …

Does Your Opponent's Gender Make A Difference? A Content Analysis Of The Use Of Gender Stereotyped Issues In Female Candidates’ Campaigns In A Mixed-Gender Versus An All-Women Races., Caley R. Hewitt

LSU Master's Theses

All-women races are steadily growing in politics as more women run with every election. While research shows how women campaign and face stereotypes when facing a male opponent or a female opponent, it does not assess how candidates may change their strategies when facing a male opponent or a female opponent. I ask if female candidates’ campaign differently on stereotypic issues between a mixed-gender election to an all-female election, specifically looking at the use of Twitter. These results showed that Democratic female candidates used more feminine-based issues facing a female opponent versus a male opponent. These results also show that …
