Whole Genome Sequence Analysis Of A Transmissible Multidrug-Resistance Plasmid Captured Without Cultivation From Poultry Litter, Emma C. Eisemann

Senior Honors Projects, 2020-current

Use of antibiotics in the agricultural industry introduces selective pressure and, consequently, could increase the presence of antibiotic resistant organisms in surrounding environments. One such environment is litter (manure and bedding) produced during large-scale poultry production in the Shenandoah Valley. Litter, with its microorganisms, is commonly applied to fields within the Shenandoah River watershed. Antibiotic resistance (AR) and virulence genes are potentially transmissible between organisms through horizontal gene transfer of genetic mobile elements, for which poultry litter could be a reservoir. The typical, culture-based approach to detecting and analyzing AR plasmids and other mobile genetic elements is limited due to …

Analyzing The Onset And Resolution Of Nonstate Conflict In The Middle East & North Africa, Emily A. Barbaro

Senior Honors Projects, 2020-current

By applying structural-functionalist theories of deviance and opposition, this thesis deconstructs nonstate mobilization in the Middle East, North Africa, Afghanistan, and Pakistan. Using data from the Armed Conflict Location and Event Dataset, the quantitative analysis interpreted both group and leader behavior in conflict situations to determine factors that influenced conflict onset and resolution. The quasipoisson regression analysis of group behavior suggested that polity and state capacity were both significant predictors of violent and nonviolent mobilization. The negative binomial regression of regime behavior suggested that civilian casualties were the most significant predictor of a government response to nonstate mobilization. Ultimately, the …

Starch is a polymer of glucose that is used as an energy store in plants. Mobilization of starch has implications in abiotic stress survival and recovery. While the importance of carbon and energy allocation in plant survival has been explored, the specific roles of starch degrading enzymes in plant responses to stress are still unclear. β-Amylase3, or BAM3, is the principle starch degrading enzyme at night and is transcriptionally upregulated in response to cold stress in the plant Arabidopsis thaliana. Using single and quadruple knockout mutant plants, I aimed to clarify the role of BAM3 in the response to …

Understanding The Failure Of Universal Healthcare Proposals In The U.S. And Paths Forward, Nicholas J. Telesco

Senior Honors Projects, 2020-current

Unlike most developed countries, the U.S. does not have a form of universal healthcare, where the government provides insurance for all citizens, despite attempts dating back to 1915. The Patient Protection and Affordable Care Act (ACA), passed in 2010 by President Obama, was a significant expansion of government power in healthcare policy, yet did not guarantee universal insurance. In recent years, universal healthcare proposals have gained traction as the U.S. healthcare system faces issues of low access, high cost, and mediocre quality. In this thesis, I intended to discover the factors that influenced the passage of past U.S. healthcare reforms …

A Novel Approach To Updating Municipal Tax Parcel Impervious Surface Calculations, Patrick D. Muradaz

Senior Honors Projects, 2020-current

Accurate impervious surface calculations are important to many municipalities due to the high volumes of surface rainwater runoff caused by high impervious surface density. Municipalities must deal with this runoff through the establishment and maintenance of drainage facilities. To help offset the added cost of these facilities, many municipalities impose taxes and fees on privately owned impervious surfaces such as homes, driveways, and patios. Currently, in order for a city like Harrisonburg to calculate tax parcel impervious surface density, aerial images must be manually digitized or mapped using computer-based classification techniques using predictive models. These methods of impervious surface calculations …

Effect Of Ambient Temperature On Recovery Of Surgically Instrumented Sprague-Dawley Rats, Gianna Mangone

Senior Honors Projects, 2020-current

Based on current guidelines for housing rodents after surgical instrumentation, rodents may be housed at temperatures that hinder surgical recovery and cause thermal stress– room temperature (21°C) being one of them. Rodents are often housed at room temperature since this temperature is easy for humans to be caring for them. However, if recovering rodents are thermally stressed, experimental results will be confounded. To address this issue, Sprague-Dawley rats were surgically instrumented with radiotelemtry thermoprobes (Data Sciences, #TA-10F40) to monitor their core temperatures, then housed at one of five temperatures to assess the effect ambient temperature had on multiple aspects of …

Novel Method To Determine Paleodiet Of Extinct Equid Merychippus Sp. Using Dental Calculus, Ranjit Z. S. Virk

Senior Honors Projects, 2020-current

Within the Miocene Epoch, the emergence of grasslands within North America coincided with the incidence of higher-crowned teeth (hypsodonty) within the proto-horse Merychippus that allowed for the inclusion of these expanding grasslands as a food source. As herbivorous paleofauna consume plant matter, microscopic remains become incorporated within dental calculus and, due to their diagnostic morphology, can be used to identify dietary components. In Merychippus, the recovery of plant microfossils holds the potential to provide greater clarity on the paleodiet of these equids. In the present study, the purpose was to quantify and compare Merychippus paleodiet constituents among sample groups. …
