Differential Lead Accumulation In Brassica Juncea, Brassica Rapa, And Lactuca Sativa And Evaluation Of Ground Level Barriers To Prevent Lead Contamination Of Produce Grown In Raised Beds, Celine Vera Richard

LSU Master's Theses

High lead (Pb) contamination of soils is a threat to human health. Urban area soils are frequently contaminated with lead from settling of gasoline exhaust, brake dust, and lead paint on homes, old playground equipment, etc. Exposure to soil-lead occurs by ingestion or inhalation and poses an elevated risk for young children. Indirect ingestion can occur through the food chain through activities such as growing certain vegetables with an ability to tolerate and accumulate lead in edible tissues. Many university extension systems recommend growing vegetables in raised beds as a reasonable reduced risk option for avoiding lead accumulation in garden …

Conservation Easement Landowners’ Willingness To Thin The Forest: A Contingent Valuation Approach, Ana Lucia Gutierrez Castillo

LSU Master's Theses

After being subject to several decades of degradation, the bottomland hardwood (BLH) forests within the Lower Mississippi Alluvial Valley (LMAV) have undergone landscape-scale restoration regimes through conservation easement programs, such as the Wetland Reserve Program (WRP) and now the Agricultural Conservation Easement Program-Wetland Reserve Easement (ACEP-WRE). Reforested easements now require landowners' adoption of forest management practices to fulfill the program's long-term conservation goals and ecosystem services thresholds. Using a contingent valuation (CV) approach, we examine easement landowners' willingness to accept (WTA) to thin their forested easement to enhance forest health and wildlife habitat quality. Results from an interval regression model …

Monitoring Of Remote Hydrocarbon Wells Using Azure Internet Of Things, Derek W. Staal

LSU Master's Theses

Remote monitoring of hydrocarbon wells is a tedious and meticulously thought out task performed to create a cyber-physical bridge between the asset and the owner. There are many systems and techniques on the market that offer this solution but due to their lack of interoperability and/or decentralized architecture they begin to fall apart when remote assets become farther away from the client. This results in extreme latency and thus poor decision making. Microsoft's Azure IoT Edge was the focus of this writing. Coupled with off-the-shelf hardware, Azure's IoT Edge services were integrated with an existing unit simulating a remote hydrocarbon …

Development Of Reduced Order Models Using Reservoir Simulation And Physics Informed Machine Learning Techniques, Mark V. Behl Jr

LSU Master's Theses

Reservoir simulation is the industry standard for prediction and characterization of processes in the subsurface. However, simulation is computationally expensive and time consuming. This study explores reduced order models (ROMs) as an appropriate alternative. ROMs that use neural networks effectively capture nonlinear dependencies, and only require available operational data as inputs. Neural networks are a black box and difficult to interpret, however. Physics informed neural networks (PINNs) provide a potential solution to these shortcomings, but have not yet been applied extensively in petroleum engineering.

A mature black-oil simulation model from Volve public data release was used to generate training data …

Social Support Modifies The Negative Effects Of Acculturation On Obesity And Central Obesity In Mexican Men, Yilin Yoshida, Stephanie Broyles, Richard Scribner, Liwei Chen, Stephen Phillippi, Jeanette Jackson-Thompson, Eduardo J. Simoes, Tung Sung Tseng

Population and Public Health Science Faculty Publications

Background: This study examined the moderating role of social support in the acculturation-obesity/central obesity relationship in Mexican American (MA) men and women. Methods: Data from NHANES 1999–2008 were used. Acculturation derived from language use, country of birth and length of residence in the U.S. Social support assessed emotional and financial support. BMI (≥30) and waist circumference (≥88 cm for women; ≥102 cm for men) measured obesity and central obesity, respectively. Weighted multivariate logistic regression models were used to describe associations. Results: Compared to less acculturation, more acculturation was associated with higher odds of obesity (ORs 2.48; 95% CI 1.06–5.83) and …

Crisis, Crisis, Read All About It! Investigating The Direct And Joint Effects Of Crisis Response Strategies, Crisis History And Strategic Actions On The Tone Of Media Coverage, Habiba Nefisa Alambo

LSU Doctoral Dissertations

Crisis management research has focused on how crisis stricken firms protect their reputation by communicating appropriate messages to evaluators and employing strategic actions that favorably shape public opinion about the stricken firm. Developing conversations have addressed how a firm’s crisis history may impact current crisis management efforts. However, little is known about how these factors jointly and directly influence what is said about a crisis stricken firm and subsequently impact evaluators’ perceptions.

Primarily guided by the tenets of attribution and situational crisis communication theories, I studied the interactive and main effects of crisis response strategies (accommodative, reframing and defensive), crisis …

College Expectation And Matriculation: High School Students Journey To Postsecondary, Sabrina Juanita Johnson

LSU Doctoral Dissertations

Racial group membership and social-economic status (SES) among academically talented students are recognized as powerful predictors of matriculation and college expectations. Moving or transitioning from high school to college is an essential pathway for success in life. Previous research suggests that college enrollment is correlated to resource opportunities available to students that they can access through their relationship with their parents, peers, school staff, teachers, and others.

These relationships are vital in increasing college matriculation by providing academic assistance, emotional support, psychological encouragement, relevant information, and guidance to students in the complex college application process.

University Faculty Design-Thinking Personas For Online Course Development: A Q Methodological Study, Jennifer Margaret Morrisette

LSU Doctoral Dissertations

To overcome the inherent complexities of planning and implementing effective online learning experiences at scale, it has been suggested that design-thinking tools and practices can be leveraged by faculty and collaborative support staff (e.g., instructional designers). However, little is known about what design-thinking approaches are perceived by faculty to be important to the online course design process, and what tools and practices might be prioritized or avoided given planning stage and individual context. Understanding these nuances would provide much needed insight to align support directly with faculty needs. This study used Q methodology to explore the subjective viewpoints of 20 …

U/Pb Zircon Ages Of Felsic Veins In The Sawtooth Metamorphic Complex, Idaho, U.S.A: Implications For Magmatism And Vein Source, Kyle Tollefson

LSU Master's Theses

Veins associated with igneous activity provide numerous insights into the geologic history of an area. The Sawtooth Metamorphic Complex (SMC) in Idaho is a roof pendent of highgrade rocks cross-cut by numerous felsic veins of unknown age and source. Obtaining U/Pb zircon geochronology of these veins can facilitate understanding the ages of magmatism in the region, their source, when nearby batholiths were juxtaposed to the SMC, and provide additional insights into the geologic evolution of the area. Each potential source of these veins has a distinct age: the Sawtooth batholith (ca. 47 Ma), the Idaho batholith (98-53 Ma), an anatectic …

Evaluation Of Louisiana Farm To School Programming: Harvest Of The Month And Local Food Procurement, Arin M. Shaffer

LSU Master's Theses

Farm to school is a growing movement that is beginning to draw serious interest in different parts of the United States due to its ability to connect communities with their local producers while providing many benefits. Farm to school entails three main components: school gardening, education and curriculum, and local food procurement. The farm to school movement is relatively new to the state of Louisiana and very little research has been conducted to evaluate the impact of the farm to school programs on local food procurement and the effect on school food environments.

Adsorption And Reconfiguration Of Amphiphiles At Silica-Water Interfaces: Role Of Electrostatic Interactions, Van Der Waals Forces And Hydrogen Bonds, Yao Wu

LSU Doctoral Dissertations

The ability to explore and predict metastable structures of hybrid self-assemblies is of central importance for the next generation of advanced materials with novel properties. As compared to their thermodynamically stable forms, the kinetically stabilized materials show improved functionality potentially over their stable counterparts. The self-assembly processes usually originate from weak intermolecular interactions, involving a dynamic competition between attractive and repulsive interactions. These weak forces, including van der Waals (vdW), electrostatic interaction and the hydrogen bonding (H-bonding), can be tuned by external stimuli, e.g., confinement, temperature and ionization, and consequently driving hybrid materials into different configurations. It is challenging to …

Synthesis And Investigation Of Amphiphilic Polypeptoids For Environmental And Biological Applications, Tianyi Yu

LSU Doctoral Dissertations

Polypeptoids are an emerging class of peptidomimetic polymers featuring N-substituted polyglycine backbones. Polypeptoids are cyto-compatible and backbone degradable, making them appealing to many biological applications. When the highly polar polyamide backbone is coupled with non-polar aliphatic side chains, polypeptoids can be considered as facial amphiphiles. Without extensive hydrogen bonding along the backbone, the conformation of polypeptoid is largely controlled by the N-substituent structures. The hydrophobicity-lipophilicity balance of polypeptoids can be readily tuned with the N-substituent structures as well as the molar ratio between the hydrophilic and hydrophobic segments in their copolymers. In view of these combined attributes, …

Ducksalad control was 89 to 99% when treated with all rates of florpyrauxifen at 11 to 29.5 g ha^-1; however, control was reduced to 51 to 79% when treated with rates lower than …

A Study Of 26al(P, Γ)27si With The Silicon Array For Branching Ratio Experiments (Sabre), Erin Courtney Good

LSU Doctoral Dissertations

The observation of the radioisotope ²⁶Al is an indicator of ongoing nucleosynthesis in the Galaxy due to its short lifetime (t_1/2 = 7.2 × 10⁵ yr) on Galactic timescales. It is thought to be synthesized in several different environments in our Galaxy, one of which is in classical novae. Classical novae are stellar explosions that occur on the surface of a white dwarf in a binary system with a main sequence star. The isotopic production resulting from the nucleosynthesis that drives these explosions can be modeled with the input of nuclear reaction rates. In recent years, many …

Population and Public Health Science Faculty Publications

Background: Comparable global data on health and nutrition of school-aged children and adolescents are scarce. We aimed to estimate age trajectories and time trends in mean height and mean body-mass index (BMI), which measures weight gain beyond what is expected from height gain, for school-aged children and adolescents. Methods: For this pooled analysis, we used a database of cardiometabolic risk factors collated by the Non-Communicable Disease Risk Factor Collaboration. We applied a Bayesian hierarchical model to estimate trends from 1985 to 2019 in mean height and mean BMI in 1-year age groups for ages 5–19 years. The model allowed for …

Service Gifts, Collective Social Connection And Reciprocity, Yihui (Elina) Tang, Christian Hinsch, Donald J. Lund, Husni Kharouf

Faculty Publications

Purpose: This study aims to investigate the process of service gifting (i.e. unexpected upgrades or benefits) and examine why service gifts do not always result in firm-beneficial reciprocal behaviors from consumers. Design/methodology/approach: Through a series of three studies including both scenario-based and game-theory-based experiments, this research proposes and empirically validates a conceptual model that examines the effect of service gifts on firm-beneficial reciprocal behaviors, and the role of collective social connection and norm of positive reciprocity (NPR) in this process. Findings: The findings of this research show that the consumer’s feelings of collective social connection mediate the link between the …

Boxwood Dieback: Molecular Detection, In-Vitro Fungicide Efficacy, And Host Susceptibility For Managing A New Emerging Disease Caused By Colletotrichum Theobromicola, Harleen Kaur

LSU Master's Theses

Boxwood (Buxus spp. L) is one of the most common and widely planted perennial ornamentals in both home gardens and commercial landscapes. Grown for its evergreen, dark green foliage, boxwood cultivation dates back to 4000 BC in Egypt. Although considered hardy, boxwood is susceptible to several plant pathogens. Recently reported boxwood dieback, a fungal disease caused by Colletotrichum theobromicola, has been spreading at an alarming rate within the United States. Boxwood dieback consists of symptoms that resemble to those caused by Phytophthora root rot, Volutella blight, and some abiotic disorders and can be easily misdiagnosed in nurseries and …

Civil War Interventions: An Examination Of The Roles Of The Media, Political Executives, And The Domestic Opposition, Jonathan Charles Nickens

LSU Doctoral Dissertations

This dissertation examines how media attention and domestic opposition parties affect third-party intervention in foreign civil wars. Previous research defines some of the ways that political executives in democratic states are constrained in their choice of actions, while also pointing out the influences and limitations of outside actors. This dissertation builds on existing research pertaining to opposition parties and the news media by providing new theories on how these outside actors can push a leader in taking an action he otherwise might not take, such as intervening in a foreign civil war. Using newly collected data, I argue that the …

Speciation-By-Depth On Coral Reefs: Sympatric Divergence With Gene Flow Or Cryptic Transient Isolation?, Carlos Prada, Michael E. Hellberg

Faculty Publications

The distributions of many sister species in the sea overlap geographically but are partitioned along depth gradients. The genetic changes leading to depth segregation may evolve in geographic isolation as a prerequisite to coexistence or may emerge during primary divergence leading to new species. These alternatives can now be distinguished via the power endowed by the thousands of scorable loci provided by second-generation sequence data. Here, we revisit the case of two depth-segregated, genetically isolated ecotypes of the nominal Caribbean candelabrum coral Eunicea flexuosa. Previous analyses based on a handful of markers could not distinguish between models of genetic exchange …
