Contrast As A Governing Principle: Topic Deployment In Selected Sonatas Of Johann Christian Bach, Morgan Hall

Master's Theses

Between the end of the Baroque era and the end of the Classical era, there was a shift in the way music was composed. This shift allowed composers to employ multiple topics in one work as opposed to the single-affect-per-movement that was standard under the Doctrine of Affections. Despite plenty of scholarship about both of the eras, the transition from one to the other has been relatively unexplored. Early musicologist Charles Burney noted in a volume of his General History of Music that there was a composer who was the first to employ “contrast as a governing principle”, and this …

"Doing Their Own Thing": The Impact Of Second-Wave Feminism At The University Of Southern Mississippi, Sarah Drivon

Master's Theses

Second-Wave Feminism was largely responsible for transforming American society’s beliefs about gender roles. However, there is very little attention given to the impact that feminism had on cultural transformations in the South. Much of the historiography of feminism and women’s liberation only covers the most radical events and leaders of the 1970s, and it neglects to point out the smaller forms of resistance that ultimately made the movement successful. During this period, the South, and specifically southern campuses, had the reputation of being against women’s liberation because there was not much evidence of resistance comparable to that of northern campuses. …

On An Unshakeable Foundation: An Archaeological Investigation Of The Postemancipation Black Community Of Bass Street, The Church They Built, And The Lasting Identity They Formed In Nashville, Tennessee, Clélie Elizabeth Cottle Peacock

Master's Theses

The Bass Street Community lived along the northern base of St. Cloud Hill in Nashville, just below the Civil War-era Union fortification, Fort Negley. The fort was built and defended by conscripted free, enslaved, and self-emancipated Black/African Americans and soldiers from the U.S. Colored Troops; some of whom stayed, built residences, founded a church, and established a shared community identity. The objects they left behind reflect a time of transition in the postemancipation urban South.

The former Bass Street Community enclave is a subset of the Fort Negley archaeological site (40DV189). My thesis examines artifacts from the Bass Street Baptist …

Vaccines At The Intersection Of Religion And Politics, Charles Downey

Biometric Assessment Of Spotted Seatrout (Cynoscion Nebulosus) From Recreational And Commercial Fisheries In Mississippi, Usa, Nimah Folake Osho-Abdulgafar

Master's Theses

Quantitative stock assessments for Mississippi’s Spotted Seatrout use length-, age-, and sex-composition data from fishery-independent sources as proxies to estimate biostatistical characteristics of fisheries harvests due to lack of sector-specific data. In Chapter 2, I examined the age, length, and sex composition of Spotted Seatrout from three fishery-dependent sectors. Between April and December 2023, I collected 210 fish (n = 19, 124, and 67 from private, charter, and commercial sectors, respectively). The length ranged between 373-535mm, 285-523mm, and 345-568mm TL, with mean ± SD lengths of 453 ± 51mm, 393 ± 57mm, and 442 ± 53mm TL, respectively. Age ranged …

Development Of A Flow Cytometry Method For The Identification And Enumeration Of Enterococcus Faecalis, Riza Magbitang

Master's Theses

A multi-color flow cytometry method coupled with fluorescent staining was developed to detect and quantify E. faecalis concentrations in coastal waters as an alternative to the traditional membrane filtration method. The developed method was used to characterize E. faecalis during batch growth and yielded consistent results across the various physiological states of the cells. Additionally, the application of propidium iodide (i.e., a viability stain), afforded the method the ability to differentiate between cells with intact and compromised cell membranes, which raises the potential of quantifying cells that are in viable-but-non-culturable (VBNC) state. Initial field test using natural seawater samples spiked …

Assessing The Impacts Of Grazing By Piney Woods Cattle And Controlled Burning On The Herbaceous Layer In An East Gulf Coastal Plain Longleaf Pine Woodland, William Mcfarland

Master's Theses

Fire and grazing are two disturbances which influence vegetation composition and diversity in many ecosystems. In the southeastern United States, longleaf pine plant communities are adapted to frequent fires and are likely to have been grazed by bison in the past. Though bison have been extirpated from this region, Pineywoods Cattle, which were introduced by the Spanish in the 16^th Century, have been fulfilling a similar role in many of these communities. This study examines the effects that combined grazing and controlled burning have on plant diversity, biomass, and community similarity in a longleaf pine savanna in the East …

An Examination Of The Strong Start Intervention To Support The Pro-Social Behaviors In At-Risk Head Start Students, Merrick Mcevoy

Master's Theses

Children from lower-income and diverse families are at a higher risk for social-emotional and academic difficulties. Implementation of early childhood interventions plays a crucial role in the healthy development of children’s social-emotional development.

The current study examined the efficacy of Strong Kids implemented as a one-on-one intervention, rather than a …

Effect Of Enzymatic Pretreatment On Biomethane Production From Olive Pomace, Ningjing Zhong

Master's Theses

In 2023, approximately 2.36 million metric tons of olive oil were produced globally. Olive pomace, a byproduct of the flesh and pits left after olive oil extraction, presents environmental challenges when used as landfill due to its high polyphenol and organic contents, or when combusted due to greenhouse gas emissions. Its potential as animal feed is limited, yet it holds promise for methane production via anaerobic digestion (AD), providing a source of renewable energy. However, the highly crystallized polysaccharides in olive pomace, such as cellulose, hemicellulose, and pectin, impede its conversion to methane, and the high polyphenol content inhibits methanogen …

Remembering, Forgetting, And Artifact Deposition In Late Prehistoric Florida, Andrew Bowen

Master's Theses

Material culture plays a fundamental role in memory processes. Artifacts are an important means of both connecting with and cutting ties with a real or imagined past. They can be reminders or symbols of connection to other people, places, things, powers, or memories, making them key components within networks and relations. The way materials are deposited or destroyed often follows specific customs or responds to environmental factors. Specific situations, like interactions with outside groups or socio-political changes, prompt particular depositional events. During the Mississippi period, such circumstances were prevalent throughout the Southeast. By treating artifacts in specific ways during deposition, …

Master's Theses

Antibiotic resistance is a growing public health concern worldwide, and for over a decade, we have been witnessing the growth of difficult to treat infectious diseases caused by bacteria that are becoming resistant to antibiotics. This resistance can be mostly related to the misusing and improper use of antibiotics in both humans and animals. To restore this problem, humans have turned to new sources for the production of antibiotics. In this study, we focused on using ants. Social insects, including ants and bees, have faced strong disease pressures during their evolution and have developed a range of methods to fight …

Novel Antivirals Unveiled Against Acute And Persistent Coxsackievirus B3 Infection Via Rapid Screening, Maria Del Mar Villanueva Guzman

Master's Theses

Enteroviruses cause 10 to 15 million infections annually in the United States, and Coxsackievirus B3 is one of the most commonly reported. Coxsackieviruses may become persistent, characterized as a viral infection that is not cleared from host cells and that generates a continuous infection. Patients who develop persistent CVB3 infection may not respond to the same antivirals as an acute infection, which may be detrimental. Therefore, there is a need for broad-range antiviral drugs to combat acute and persistent CVB3 infection, as there is no well-accepted treatment available. We developed a model system to study persistent CVB3 using a pancreatic …

Loverboy Rules: A Transtheoretical Exploration Of Andy Bernard's Failed Masculinity, Jessie Marta Olstad

Master's Theses

NBC's U.S adaptation of The Office is one of the most well-known sitcoms to come out of modern television, surpassing its original British counterpart’s two seasons with its own nine. It is a representation, as well, of the time it aired (2005-2013), reflecting on the modern American workplace and the everyday person. Within it, The Office also reflected how society was constructed at the time with its humor surrounding gender, homosexuality, and race – as a tolerant but not welcoming atmosphere to people who were not white, heterosexual, men. More specifically, The Office presents multiple adaptations of masculinity to teach …

Neurogenomics Of Competition And Parental Care In A Socially Polyandrous Shorebird, Tessa Mathur Patton

Master's Theses

Despite sharing largely similar genomes, females and males of the same species exhibit morphological, physiological, and behavioral differences. Sex-role reversal stems from a unique case of sexual selection in which females compete for mates and males conduct the majority of parental duties. We examined the extent to which aggression and parenting may be mediated by different neurogenomic mechanisms by comparing females versus males in the northern jacana (Jacana spinosa), a sex-role reversed shorebird. We hypothesized that sex differences in neural transcriptomic profiles explain sexual dimorphism in behavior. We conducted RNA-Seq in two brain regions within the social behavior network: the …
