Developing A Novel Place Preference Assay To Compare Drosophila Species Over Time, Martha M. Brinson

Honors Theses

Across phylogeny, integration of external factors, memory, and internal states of the organism dictate organismal behavior and mechanisms. The underlying genetic components can affect these behaviors such as in genomic changes arising from speciation. In this thesis, a new place preference assay was evaluated in the analysis and investigation of two species of Drosophila flies (D. melanogaster and D. simulans) to measure similarities and differences and their attraction to two different food substrates. Sleep and circadian measurements were also recorded during experimentation. The Drosophila Activity Monitor 5M (DAM5M) System and Sleep Circadian Analysis MATLAB Program (SCAMP) analysis were …

Stature Estimates Of The Classic Period Maya From Chac Balam And San Juan, Ambergris Caye, Belize, Natalie Clark

Honors Theses

This thesis presents updated sex and stature estimates for ancient Maya females and males who lived in San Juan and Chac Balam in northern Ambergris Caye from approximately AD 700-900.

The regression formulae used in this study reflect a closer population affinity to the Maya compared to the equations used in the original analysis by Glassman (1995). Del Angel and Cisneros’ (2004) formulae were used when estimating stature based on a complete long bone. In Steele and Bramblett (1988), Steele and McKern (1969) and Steele (1970) regression formulae were used when estimating stature based on an incomplete humerus, femur, or …

A Study Of Cannabigerolic Acid And Its Derivatives Via Raman Spectroscopy And Density Functional Theory, Trevor Wolfe

Honors Theses

The cannabinoids are a class of molecules endogenous to the cannabis plant. Their scientific relevance has increased in recent years due to the mercurial legal status of marijuana across the United States. Some of the most known are cannabidiol (CBD), δ9-tetrahydrocannabinol (δ9-THC), and δ8-THC due in large part to their widespread use, especially in states where marijuana and related products are legal. However, cannabigerolic acid (CBGA) is arguably the most important cannabinoid; it is enzymatically converted into other acidic cannabinoids, which subsequently undergo non-enzymatic processes (isomerization, thermal decarboxylation, oxidation, etc.) to synthesize further cannabinoids. Although there is a wealth of …

Student Engagement And Performance Assessment As Associated With Three Types Of Integument System Laboratory Activities, Sophie Deoliveira

Honors Theses

Students participating in anatomy education, specifically an Anatomy and Physiology classroom, have shown difficulty in learning and retaining information on the various systems of the body. This study sought to assess the benefits of different learning activities associated with student engagement and performance on subsequent examinations regarding the integumentary system. For this study, three different hands-on laboratory activities (i.e., treatments) were given during different laboratory sessions. These hands-on activities included labeling a three-dimensional model, illustrating a model, or building a model of the integumentary system using materials provided. Students then completed a post-laboratory questionnaire regarding their enjoyment of their particular …

A Performance Analysis Of The Belle Ii Detector, John Stacy

Honors Theses

The Belle II experiment has recently (2018) started data taking at the SuperKEKB electron-positron collider in Tsukuba, Japan. Detector performance studies are necessary to understand early data and prepare for more complex analyses. This study of the proton detection efficiency of the Belle II detector compares real and simulated data to find discrepancies with the intention to provide useful information for detector and calibration experts to better gauge detector performance. It also attempts to improve the characterization of proton identification efficiency at low momenta, which performs poorly under the current fitting model. This helps analysts exploring final states that include …

Invasion Of The Northeastern United States By The Southern Pine Beetle, Dendroctonus Frontalis, And The Impacts On Signatures Of Isolation By Distance Assessed Using Mitochondrial Dna, Lora Grace Holman

Honors Theses

The southern pine beetle (SPB) is a small, black beetle that parasitizes pine trees across the United States and Central America. Recently it has been recognized that the range of SPB is not limited to the southern United States, but rather extends northward across the eastern United States, which raises concerns for pine trees that have never encountered the pest before. Using mitochondrial DNA sequences from a section of the cytochrome oxidase I gene and four different measures of genetic distance compared to geographic distance, we tested for evidence of isolation by distance (IBD) among sampled SPB to see whether …

Lifetime Measurement Of The Xi_C^+ Using Belle Ii Monte Carlo, Paul Gebeline

Honors Theses

This analysis uses simulated data from the Belle II experiment to measure the lifetime of the Xi_c^+ baryon. Three different decay modes are investigated to explore the feasibility and accuracy of such measurements at Belle II. The Xi_c^+ lifetime is measured using one of these modes after reducing backgrounds from sources other than the decay of interest. The final result is 464 +/- 15 fs, which is consistent with the expected result of 442 fs within uncertainty. This result shows that Belle II can make competitive measurements of particle properties and decays.

Lectin-Glycan Complexes: A Comprehensive Analysis Of Docking Calculations, Ashton Custer

Honors Theses

Lectins are a type of glycan-binding protein that noncovalently bind glycans. Carbohydrates are molecules consisting of sugar units joined together. Glycans are carbohydrates. Hence, glycans are also sugars. Lectins and lectin-glycan complexes have a range of biological roles and can be found in animals (including humans), plants, bacteria, viruses, and yeasts and fungi.¹ Many scientists focus on the computational study of these complexes due to their intricate roles in many living organisms. Computational study is important in furthering our knowledge of lectin-glycan complexes and other such protein complexes. However, computational study is not perfect. There are many challenges in …

Computational Investigations Into Astrochemical Inorganic Oxides, Ammonia Borane, And Genetic Algorithms, E. Michael Valencia

Honors Theses

The formulations of quantum mechanics in the early 1900s were exciting theoretical discoveries, but were not practical to apply until the advent of computers and the subsequent computational methods in 1951. With the introduction of tractable simplifications, procedures such as Hartree-Fock allowed for determination of properties of non-trivial systems. Presently, huge leads of computational power have allowed for extremely precise, quantitative work that can be applied to the human body, synthesis, or even astrochemical processes. This thesis presents works concerning 1) the history of quantum mechanics; 2) a brief primer on computational chemistry and its methods; 3) inorganic oxides in …

The Femicide Epidemic: A Case Study Analysis Of Governmental Response And Recommendations For Combatting Femicide In El Salvador, Chloe Rizk

Honors Theses

Femicide refers to the misogynistic killing of women by men. Globally, femicide is the leading cause of premature deaths for women. El Salvador notoriously has one of the highest femicide rates in the world. This thesis analyzes the effectiveness of current Salvadoran governmental responses to femicide using quantitative and qualitative analysis. This research found that, despite a lack of enforcement, there was a relative reduction in femicide rates following major governmental responses. Most notably, following the passage of VAW-focused laws from 2011 to 2012 and the appointment of a particular unit to investigate gender-based violence, femicides in El Salvador decreased …

Ab Initio Study Of The Rotation Of The C≡C Group In Benzvalyne, Advait Praveen

Honors Theses

For benzvalyne, we have characterized the minima and transition states of the molecule using the B3LYP, MP2, and M06-2X methods and aug-cc-pVTZ basis set. This was done by calculating the energy of the molecule while rotating the alkyne bond contained within it. After the initial rotation, optimized parameters for the molecule are found. Following this, imaginary frequencies were attempted to be found at the local maximum produced by the graph of the Energy v. rotation angle. Should the negative frequencies be found, the energy of the molecule will be characterized by the CCSD (T) method and aug-cc-pVQZ basis sets. This …

Comorbidity Burden And Covid-19 Vaccination Intention: Application Of The Health Belief Model, Michael Raymond

Honors Theses

The COVID-19 pandemic impacted many aspects of American’s lives causing over 79 million cases and over 950,000 deaths. Existing research shows severity of COVID-19 infection may be linked to number of underlying health conditions, known as comorbidities. The objective of this study was to determine if comorbidity burden was associated with intention to vaccinate against COVID-19. This relationship was looked at through the Health Belief Model (HBM) and its mediating variables of perceived susceptibility, perceived severity, perceived benefits, and perceived barriers. Our sample was compromised of 350 individuals recruited from an online platform who were not already vaccinated against COVID-19. …

Honors Theses

This thesis discusses the similarities and differences in Tanzanian COVID-19 policies implemented by the late President John Pombe Magufuli and his successor, President Samia Suluhu Hassan. It also analyzes the responses of Tanzanian citizens to these different policies as expressed in the media. The conclusions that were made in this thesis are based on qualitative analysis of articles published in Tanzanian-based newspapers during specific time periods surrounding significant policy changes during each presidency. The situation of COVID-19 policies in Tanzania is unique due to the differences in the COVID-19 policies implemented in comparison to those implemented by other countries and …

Computational Electronic Spectroscopy Predictions For Astrochemical Ice Analogues And Data Analysis For Experimental Spectra, Austin Wallace

Honors Theses

Theoretical chemistry aims to acquire wavefunctions for systems to calculate physical observables to help guide experimentation or provide rationale for particular observations. While quantum chemistry has expanded well beyond Hartree-Fock theory to produce more accurate predictions or faster computational times, this theory has formed the foundation of the field through providing a means to solve the electron-electron repulsion term as simply an average field and to acquire converged molecular orbitals through the self-consistent-field method. When attempting to describe large molecular systems that can populate many microstates, the Boltzmann distribution provides a means for determining the relative abundances of each microstate …

Antibiotic-Resistant Bacteria In Freshwater Crayfish, Colby Finch

Honors Theses

The presence of antibiotic-resistant bacteria is increasing in natural aquatic environments. Alongside this, organisms that live in these ecosystems are increasingly harboring antibiotic-resistant bacteria. In this study, I analyzed the capacity for the crayfish species Procambarus vioscai paynei to harbor antibiotic-resistant bacteria. Crayfish, as well as water and sediment, were sampled from a pond at the University of Mississippi Field Station. The guts of crayfish were plated on TSA agar, as well as agar containing vancomycin, erythromycin, penicillin, tetracycline, or ciprofloxacin. Following incubation, counts of bacteria were determined. Selected bacterial isolates were tested for multiple antibiotic-resistance. Bacterial isolates were also …

Investigating The Role Of Small Rna Pathways In Arabidopsis Shoot Gravitropism, Julia Lott

Honors Theses

The plant stem grows against the gravitational force, a phenomenon called negative gravitropism. In the model dicotyledonous plant Arabidopsis thaliana, gravity is sensed by starch-filled amyloplasts, which trigger the shoot gravitropic response through the action of a growth hormone called auxin. In the darkness, a group of transcription factors named PHYTOCHROME-INTERACTING FACTORS (PIFs) promote stem negative gravitropism by inhibiting the starch metabolism in the endodermal amyloplasts. Red light promotes starch metabolism and converts amyloplasts into other types of plastids (e.g., chloroplasts) through the red/far-red light photoreceptors—phytochromes. Consequently, red-light-grown seedlings lose starch granules in amyloplasts and exhibit agravitropic growth. However, the …

Reconstructing The Concept Of Organizational Crisis: Using The Historic Case Of Mississippi Chemical Corporation, Carley Horner

Honors Theses

In today’s volatile business environment, organizations are increasingly facing multiple threats that may engender crises of varying scope and intensity. While organizational leaders are intensifying their efforts to understand the nature of crises, there is no consensus in the academic community over the conceptualization of crises. In past studies, researchers have conceptualized a crisis either as an event or a process. This conceptualization is grounded in the assumption that the leader is an objective observer and actor in reaction to a crisis. By analyzing my transcribed interviews of the crisis leaders at Mississippi Chemical Corporation, I have identified two additional …

Rates And Perceptions Of Covid-19 Vaccination From University Of Mississippi Students, Josie Parham

Honors Theses

The trials, tribulations and triumphs of the global COVID-19 pandemic are impacted by and are a product of behaviors that occur at the level of nations, states, cities and, ultimately, communities. In the wake of the development of safe and effective vaccines against SARS-CoV2, the virus responsible for the pandemic, the significance of the vaccine is closely linked to the number of individuals that receive the vaccine. To date, surveys have measured sizable variations in vaccination rates between nations, states, cities, and communities. Focusing on events that have transpired in one such local community, the present study (i) measured the …

Comparative Analysis Of Imputation Methods In Real Estate Data, Connor Donlen

Honors Theses

This project involves comparing different methods of missing data imputation in the context of predicting real estate listing prices. These methods are compared against each other in both their ability to recreate the original data and their effects on a final predictive model. In order to evaluate their effectiveness, first, a predictive model is made using the complete dataset to use as a benchmark for the imputed datasets. Then, a complete dataset is split into 80% training and 20% testing datasets, and missing values are created in the training data using two different missing data mechanisms, missing completely at random …

Intensive, Interprofessional Therapy: A Case Approach, Emma C. Schrotenboer

Honors Theses

This research looks at the impacts of intensive, interprofessional therapy for children with disabilities. There is very little literature currently published on this topic, although what is available generally finds that more intense therapy is more beneficial. The child who was studied was a camper at Adam’s Camp therapy camp, a week-long program that involves six hours of therapy each day with therapists from five different fields. Her progress over the week, as well as her retention of skills several weeks later, were determined by pre- and post-camp surveys sent to the mother and the therapists’ notes from during the …

Application Of The Formal Design Of Experiments To Deformed Airfoil Testing, Alex Ligman

Honors Theses

Traditionally, one factor at a time (OFAT) testing is used to accomplish wind tunnel
experimentation. OFAT testing is a process whereby one of the defined factors in the experiment is changed while all of the other factors are held constant. Afterwards, a new factor is chosen as the one to be manipulated, and the process is then repeated until all factors have been run through. Due to the possible cost-intensive and time-consuming nature of wind tunnel testing, formal design of experiments (DOE) has begun to be applied to wind tunnel experiments. In doing so, unique analyses can be made that …

Honors Theses

Each year, the seniors in the Haley Barbour Center for Manufacturing Excellence complete a capstone project. A team comprised of seniors in varying disciplines work to develop a business model focused on producing a specific product. This team, SEC Rivals Checkers, chose to produce wooden checker boards where each half of a board is custom to a specific SEC school. These halves were designed to be interchangeable, so a variety of different combination could be created when utilizing the product. Through initial marketing analysis, cost estimation, prototyping, and process development, the original SEC Rivals Checkers idea was developed into a …

Novel Keyed Fusion Method To Improve Plate Alignment In Anterior Cervical Discectomy And Fusion Procedures, Henry Seiler

Honors Theses

Anterior cervical discectomy and fusion (ACDF) is a form of neck surgery that is performed to remove a damaged disc in the spine. Without intervention damaged discs in the spine cause a buildup of spinal cord or nerve root pressure which can lead to several unpleasant side effects. The current methods and devices through which this surgery is carried out can be potentially problematic for both the surgeon and the patient. Oftentimes surgeons have difficulty aligning the cervical plate typically used in ACDF surgeries. In many cases, these problems are unavoidable. It is for this reason that a group of …

Developing New Crutch Tip Design For Overall Increased Stability And Improved Movement On Different Terrains, Lauren Skinner

Honors Theses

Crutches are a mobility assistive device that are often used in various situations, such as post- surgical rehabilitation and recovery after injury. The current crutch tip design that is used on today’s crutches are often unstable and do not provide quality movement on different terrains, such as snow, ice, mud, and wet surfaces. These problems would be solved with a new tip design that could be attached to existing crutches or manufactured with the crutch itself. The team’s solution to this problem is a crutch tip with modular parts. The tip would attach to the shaft of the crutch like …

Pendulums Of Personhood? Exploring The Multitudes Of Immigrant Womanhood In Spanish-Maghrebi Literature, Kaitlyn C. Sisco

Honors Theses

Often considered articulations of in-between-ness and bearers of fraught selfhoods, the work of Spanish-Maghrebi authors has been widely debated in literary fields, with academics arguing that it constitutes a largely homogenous set of texts about the standard immigrant experience. However, by placing these texts in a single category, such arguments end up erasing the immensely varied identities expressed and represented by Spanish-Maghrebi authors. This thesis seeks to address this issue by paying particular attention to how Spanish-Maghrebi authors negotiate different types of immigrant subjectivities in their writing. Specifically, I analyze the works of three contemporary Spanish-Maghrebi writers, Najat El Hachmi, …

Effects Of Waterborne Benzo[A]Pyrene Embryonic Exposure On Development, Behavior, Reproduction, And Mitochondrial Bioenergetics In Zebrafish, Megha Patel

Honors Theses

Benzo[a]pyrene (BaP) is a polycyclic aromatic hydrocarbon (PAH) that is a known carcinogen leading to adverse effects in the development of both humans and animals. BaP is also continuously present in the environment leading to regular exposure via inhalation or ingestion. Because organisms’ early life stages can be more susceptible to contaminant exposure, our focus was on BaP’s adverse impacts on survival, length, weight, behavior, bioenergetic state, and fecundity following developmental exposures. To study BaP’s impacts, zebrafish (Danio rerio) were used as a model organism. BaP is a ligand for the aryl hydrocarbon receptor (AHR in humans; Ahr in …
