Policy Analysis: Alaska Salmon Hatcheries, Jessica Eller

Graduate Student Theses, Dissertations, & Professional Papers

Using an adapted Ecological Risk Assessment (ERA) - Evaluation, this study analyzes policy regulating Alaska salmon hatcheries to evaluate its effectiveness at sustaining wild salmon runs.When Alaska became a state in 1959, its salmon industry was suffering from years of overfishing. Runs were at an all-time low, prompting constitutional drafters to mandate management of salmon via the sustained yield principle. The hatchery system that operates today and is responsible for a third of the commercial catch each year was put in place in the 1970s to help supplement depressed salmon runs. The effects of hatchery salmon on wild salmon populations …

The Forensic Characterization Of Bacterial And Fungal Organisms In Traditional Chinese Medicine, Julia Grzymkowski, Christopher J. Ehrhardt, Justin L. Poklis, Michelle R. Peace

UROP Posters

There has been an increase in use of Traditional Chinese Medicine (TCM) in the United States because they are less expensive and believed to be more effective with less adverse effects in comparison to traditional pharmaceutics. Therefore, sales have increased in the US, despite articles and case studies demonstrating the dangers, such as injury and death, related to TCM, stemming from improper labelling, toxic contaminants, and, in some cases, the presence of pathogenic bacteria. The aim of this study was to perform a survival experiment to demonstrate the importance of proper herbal brewing technique and to conduct a molecular and …

The Impact Of Various Instructional Strategies On Student Engagement With Mathematics, Sidney Scott

Honors Theses

The purpose of this research is to investigate the variation of student engagement with mathematics depending on the instructional method implemented in a secondary classroom. I looked into the strategies of lecture, group sessions, and direct instruction. In order to compare the student engagement among the methods, I developed a checklist instrument to verify when students were engaged based on seven indicators of engagement — teacher-led questions, student-led questions, showing work on the board, group work, growth between formative assessments, nonverbal engagement, and the use of differentiation. My findings show that the group sessions scored higher on the engagement indicator …

Energetics And Vibrational Signatures Of Nucleobase Argyrophilic Interactions, Suhwan Paul Lee

Honors Theses

This study investigates the interactions of both purine (adenine and guanine) and pyrimidine (cytosine, thymine, and uracil) nucleobases with a pair of silver atoms (Ag2). Full geometry optimizations were performed on several structures of each nucleobase/Ag2 complex and the corresponding isolated monomers using the M06-2X density functional theory (DFT) method with a correlation consistent triple-ζ basis set augmented with diffuse functions on all atoms and a relativistic pseudopotential on Ag (aug-cc-pVTZ for H, C, N, and O and aug-cc-pVTZ-PP for Ag; denoted aVTZ). Harmonic vibrational frequency computations indicate that each optimized structure corresponds to a minimum on the M06-2X/aVTZ potential …

On A Pseudodifferential Calculus With Modest Boundary Decay Condition, Binbin Huang

Graduate Dissertations and Theses

A boundary decay condition, called vanishing to infinite logarithmic order is introduced. A pseudodifferential calculus, extending the b-calculus of Melrose, is proposed based on this modest decay condition. The mapping properties, composition rule, and normal operators are studied. Instead of functional analytic methods, a geometric approach is invoked in pursuing the Fredholm criterion. As an application, a detailed proof of the Atiyah-Patodi-Singer index theorem, including a review of Dirac operators of product type and construction of the heat kernel, is presented.

Mapreduce And Heterogeneity: Power-Aware Bag-Of-Tasks, Framework Parameter Sensitivity, And Dynamic Cluster Aware Framework Configuration, Jessica L. Hartog

Graduate Dissertations and Theses

This dissertation presents the techniques for adaptation of MapReduce frameworks to incorporate heterogeneity-aware scheduling algorithms, an inspection of cluster configurations and how they impact these scheduling algorithms, an analysis regarding how the cluster configuration and the heterogeneity-aware scheduling can work together to minimize turnaround time and/or power consumption of the cluster when executing MapReduce applications, and how these lessons can be applied more broadly to Big Data infrastructure outside of MapReduce that supports multiple Big Data frameworks simultaneously.

Heterogeneity exists in various capacities in any given cluster, from static (Physical and Platform) heterogeneity to dynamic heterogeneity (Transient Data, Transient Applications, …

Heritable Variation In Reward Sensitivity And Impulsive Cction And Choice In A Genetically Diverse Inbred Mouse Panel, Lauren S. Bailey

Graduate Dissertations and Theses

Research in animal models and human subjects points towards reward sensitivity and impulsivity as being characteristics that predict greater positive subjective responses to stimulant drugs. The Collaborative Cross (CC) recombinant inbred mouse strains and their inbred founders are a powerful genetic reference panel that has potential as a tool for revealing genetic correlations. The CC/DO founder strains were used to examine the heritability of reward sensitivity and impulsivity traits. Founder strains were tested for activity in an open field, reward sensitivity, and reversal learning (impulsive action) or delay discounting (impulsive choice). Significant heritability for anticipatory responding within the reversal task, …

The Shape Of Diversity: A Morphometric Analysis Of Late Archaic Bifaces From Lamoka Lake, Samuel M. Bourcy

Graduate Dissertations and Theses

The general assumption of Late Archaic peoples in the Northeast is that they were one homogeneous culture group, but through the study of Lamoka Lake bifaces found at the Lamoka Lake Site, as well as applying the concepts of community of practice, I have shown that tool shape variation could indicate distinct social groups. Using computer software to digitally outline bifaces I compared the shape of over 400 bifaces from Lamoka Lake and statistically analyzed their morphologies in order to provide material correlates of social diversity. Whether this morphological variation is representative of the conscious or unconscious design choices made …

Multi-Objective Design Optimization Of A Mobile-Bearing Total Disc Arthroplasty Considering Spinal Kinematics, Facet Joint Loads, And Metal-On-Polyethylene Contact Mechanics, Chaochao Zhou

Graduate Dissertations and Theses

Total disc arthroplasty (TDA) is a motion-preserving surgical technique used to treat spinal disorders, when more conservative medical therapies fail. Unfortunately, a high incidence of revision surgery exists due to postoperative complications including abnormal kinematics, facet joint arthritis, and implant failures. However, TDA is still an attractive option, since an optimally designed artificial disc is expected to reproduce native segmental biomechanics. Correspondingly, it would mitigate the development of adjacent segment diseases (a major concern of spinal fusion) caused by altered segmental biomechanics.

Design optimization is a process of finding the best design parameters for a component/system to satisfy one/multiple design …

We describe an application written to automate a calculation for the mathematical research of Dr. Spiroff of University of Mississippi & Dr. Enescu of Georgia State University. This work represents a way to overcome the barriers of the mathematical calculations in obtaining theoretical results.

Using Their Own Voices: Exploring The Writing Of English Language Learners In A Mississippi Middle School, Gabrielle Lynn Vogt

Honors Theses

In the United States, and particularly Mississippi, the number of K-12 English Language Learners is growing rapidly. Writing scores are on a national decline, and ELLs are struggling to acquire the language and literacy skills to become proficient writers in English. However, there are various instructional approaches that provide ELLs the opportunity to use and expand their writing skills beyond a basic ability. Despite this, little is being done to give ELLs the opportunity to express themselves and their identities while also acquiring stronger writing skills. As a preservice teacher, I developed a mixed methods research study that explored the …

Studies Of Carbonaceous Materials Using Raman Spectroscopy, Cameron L. Smith

Honors Theses

Various carbonaceous materials including graphene, treated biochar, and C60 were studied using Raman spectroscopy with particular attention given to the treatment process and the Raman enhancement methods. Such studies that focus on the treatment process are useful in determining the extent to which the species was affected via shifts in the Raman peaks. Previous collaborations have proven successful when multiple samples were studied and analyzed. The attempt to create a novel Raman enhancement technique via combination of two previously recorded techniques was ultimately unsuccessful but further work is necessary.

Effects Of Predation On The Biochemical Constituents Of The Bleached Soft Coral Sinularia Polydactyla, Carley Elizabeth Cole

Honors Theses

Climate change can indirectly affect the level of predation on soft corals. As sea temperatures rise, more and more bleaching events are occurring, which can affect the production of chemical defenses and the concentrations of the biochemical constituents that make up the soft corals. These changes may make the soft corals more attractive to predators. This phenomenon is suggested by the environmental stress theory (EST), which states that under stressful conditions, more of an organism's energy is allocated to survival rather than to other factors, such as reproduction or predator deterrence. To test the effect of predation on already bleached …

Classifying #Metoo Hash-Tagged Tweets By Semantics To Understand The Extent Of Sexual Harassment, Claire Hubacek

Honors Theses

This thesis contains a program that will process tweets from Twitter that use the hashtag "#MeToo" and categorize them by their relevance to the movement, their stance on the movement, and the type of sexual harassment expressed (if applicable). Being able to work with a narrowed set of tweets belonging to a specific category creates the capacity to do more in-depth research and analysis, exploring Twitter as a special platform for discussing these sensitive topics and showing that this online space for expressing personal experiences has delivered unprecedented potential avenues of study. This thesis also contains research into additional solutions …

An Analysis Of Commercial Oxidative Hair Dyes Using Raman Spectroscopy, Allyson Henke

Honors Theses

Here, we aim to further the potential use of surface-enhanced Raman spectroscopy (SERS) in analyzing hair dyes for use in forensic investigations. Current methods include light microscopy and thin-layer chromatography (TLC). However, these techniques can be destructive to the hair samples, do not have high discriminatory power, and have had problems with giving inconclusive results. Raman spectroscopy, on the other hand, is a fast, simple technique with a high discriminatory power. Previous work has shown that SERS can be used for in-situ analyses that is not destructive to the sample. This previous work also demonstrated that SERS could definitively differentiate …

Raman Spectroscopic And Computational Study Of Hydrogen Bond Interactions Between Guanidine Hydrochloride, Trimethylamine N-Oxide (Tmao), Urea, And Water, Andrew Kamischke

Honors Theses

Proteins are broken down in the body and produce water, CO2, and ammonia as by-products. Ammonia is toxic to cells, making it a priority to be excreted. Urea is the key route for the transportation of ammonia out of the body and is the main component of urine. Guanidine is another important nitrogen-containing molecule that is structural like urea and plays important biological roles in the stabilization of proteins. Guanidine hydrochloride and Urea are known to denature proteins and this functionality continues to be a topic of great interest. Urea and guanidine contain many hydrogen bonding sites and interactions with …

The Path To Math: Analysis Of Student Mathematical Stories, Aurora D. Wallace

Honors Theses

In this thesis, I address the issue of American students' dislike of mathematics. I explored this issue in two parts: distributing a survey to undergraduates of the University of Mississippi and then conducting interviews of students at the same university about their past feelings and emotions about mathematics. Interview data was analyzed and coded through Dedoose, a qualitative data program. Analysis of each interviewee's data set led to the establishment of different mathematical paths that students follow in their mathematics education. The five paths emerging from the data — Arrow, Improvement, Revelation, Sparkless, and Almost Revelation — provide a more …

Assembly Of A Protein-Based Hydrogel As A Vehicle For In Situ Drug Delivery, Austin Carroll

Honors Theses

The goal of this work is to develop a self-assembling, protein-based gel to deliver drugs at the site of chronic inflammation. There are two engineered protomers that comprise the gel; calmodulin- and M13- are their critical components. Numerous enzymes have been shown to undergo calcium-dependent regulation by calmodulin, an intracellular protein highly resilient to its chemical environment. One of these enzymes, myosin light chain kinase, contains a remarkable 26 residue portion known as the M13 peptide that has been demonstrated to bind to calmodulin in the presence of calcium through hydrophobic interactions. Because the extracellular space in vivo constitutes an …

The Impact Of Social Wellness Integration On Fifth Grade Students' Positive Social Behaviors, Kathryn Harrison

Honors Theses

In recent years, schools across the United States have encountered increased pressure to focus solely on academic performance (Dillow & Snyder, 2007). Therefore, time allotted to developing fundamental social skills needed to improve the well-being of children in elementary school has decreased. However, social skills are essential to educating the overall well-being of children (Clinton, West, and Wilson, 2017). Benefits associated with social wellness education include relationship skills, responsible decision making skills, and consideration of well-being of self and others. These are all important to lifelong success (Burrow, Patrick, Kyzer, & Mckelvey 2016). To address these concerns, this study examined …

Social And Emotional Learning And Its Implementation In A Standard 9th Grade English Language Arts Curriculum, Mary Kathryn Barry

Honors Theses

The basis of the thesis is to examine effective teacher practices through the research of social and emotional learning, examining both teacher behavior and best teaching practices and how these two influences impact students' reception of the curriculum. The literature review will be divided in three parts: a pedagogical overview, the importance of critical reflection for teachers, and how empathy, in partnership with other thinking operations and qualities of character, effect student's capacity to connect to the curriculum. Following the literature review is a curriculum design. This curriculum design serves to demonstrate an example of how social and emotional learning …

Purkinje Cell Morphology And Display Complexity In Manakins (Pipridae), Mary Harvey

Honors Theses

Manakins are a suboscine, lekking bird of the tropical and subtropical regions of South and Central America that perform complex mating displays shaped by sexual selection. The complexity of the mating display varies greatly across species of manakins. Some manakins only perform a limited number of different motor elements, whereas others have elaborate displays that consist of acrobatic movements and mechanical sound production. The complexity of these displays has been found to be positively related to brain weight, brain volume, arcopallium volume, body weight, and tarsus size but shows no relationship to the nucleus rotundus or nucleus taeniae. The volume …

Development Of A Gel Assay For Analysis Of Bovine Milk Casein, Masa Miscevic

Honors Theses

The main purpose of this research was to develop a gel assay for analysis of casein samples for ultimate application for studies of in vitro models for stomach and intestinal processing of dairy products in adults and infants. It is proposed that casein completely dissolves and is digestible in simulated gastric, and is somewhat soluble and digestible in simulated intestinal environments of adults and infants. The following experimental methods were devised to thoroughly examine behavior and properties of casein originating from different sources in range of solvents and varying pH values. First, casein was enriched in comparison to soluble materials …

The Policy Evolution And Privatization Of Commercial Space Systems, Nestor Delgado

Honors Theses

From the Wright Brothers to SpaceX launching the Falcon Heavy, space systems, and the policies that govern these systems, continue to evolve at a rapid rate. However, as space travel becomes commercialized, the federal government is beginning to realize that it would be cost-ineffective to continue to manufacture, maintain, and operate space systems completely through their own agencies. In result of this, it would be proactive for policymakers to decide what policy tools would be most effective in regulating space systems and the space ports in which they travel. The purpose of this study is to present research on the …

Purification Protocol Development And Analysis Of Binding Properties Of Calmodulin Collagen-Like Protein, Patrick P. Boddie

Honors Theses

Calmodulin is an intensely studied, intracellular, calcium-binding protein that is involved in diverse physiological processes. When bound to calcium, calmodulin undergoes a conformational change that allows it to bind specific target peptides with high affinity, one being the calmodulin binding region of myosin light chain kinase, herein called M13. This high affinity, calcium dependent association has made it a desirable choice for use in a biomaterial for drug delivery for non-steroidal anti- inflammatory drugs (NSAIDs). Two artificial genes have been designed by our lab for use in the proposed biomaterial: calmodulin collagen-like protein (CCLP), a construct composed of two calmodulin …

Philosophies In Action: A Personal And Analytical Look Into Reflective Teaching, Ryley Blomberg

Honors Theses

In this thesis, I will address the implementation of reflective teaching into everyday practice and how this reflective teaching impacts teacher actions and decisions in classrooms and schools. I engaged in reflective teaching for a semester of my student teaching practicum experience, focusing extensively on my philosophy of education, its evolution, and its implementation. Additionally, I interviewed in-service teachers at a rural Mississippi high school on how they engage in reflective practice and implement their philosophies into their teaching daily. The research from both the journals and interviews was uploaded into a qualitative data analysis software where it was analyzed, …

Post-Translational Modification Of Hypoxia-Inducible Factor Proteins By O-Linked -N-Acetylglucosamine In Breast Cancer Cells, Sean Williamson

Honors Theses

One of the hallmarks of cancer is its ability to adapt its metabolism to survive and thrive despite needing to overcome significant energy barriers and low oxygen settings in order to do so. The hypoxia-inducible factor proteins (HIFs) play important roles in the processes in which cancer fulfills these requirements. The O-linked -N-acetylglucoseamine (O-GlcNAc) can be attached to cellular proteins through O-glycosylation, and is thus considered a potential target for anticancer mechanisms. HIFs are composed of (HIF-1 and HIF-2, respectively) and subunits. This research found that O-GlcNAc is able to attach to and modify the HIF proteins. This was accomplished …

Connecting The Mind And Body In Ancient Greek Medicine, Taylor Ferris

Honors Theses

I investigated Greek medicine and healing shrines in antiquity and focused on the issue of the mind-body connection and how this phenomenon was understood in antiquity. I researched the Athenian plague of 430-425 B.C., sleep and dreams, particularly in the Rites of Incubation, and Hippocratic medicine as well as religious medicine in order to understand more deeply the origins of Greek medicine and how the healing phenomena were practiced and understood. I have come to a greater understanding of this connection between the mind and the body and have come to redefine the placebo effect and argue that the mind …

The Impact Of Expectations On Student Perceptions, Taylor A. Huey

Honors Theses

The impact of expectations on student achievement has been researched for decades. My study began with the intention of researching and recording the impact of my own expectations on low-achieving students. However, the focus of my research evolved after meeting and building relationships with my students. After observing the exceedingly low standards my students held for themselves, my interest shifted to how expectations impacted students' self-perceptions. I recorded my observations of their attitudes, behaviors, and work ethic throughout the year; I also gave them an anonymous survey at the end of the year questioning them about their aspirations for the …

Studying The Effects Of Hydrogen Bonding In 1h-1,2,3-Triazole And Its Derivatives, Leah Alexandra Wallace

Honors Theses

1,2,3-triazole is used as a building block in many pharmaceutical drugs. The molecule has several derivatives that are useful in other areas including treating fungal infections and in dealing with some environmental issues. One of its derivatives, benzotriazole, is commonly used as an inhibitor of corrosion through the formation of a copper-benzotriazole complex. One area of particular interest in studying triazoles is the ability of these molecules to tautomerize. The hydrogen atom can move from the 1H position to the 2H position and this transfer is thought to be affected by solvent interactions. Here, we study the effects of hydrogen …
