Pathways To Justice: Positive Rights, State Constitutions, And Untapped Potential, Dustin Coffman

Marquette Benefits and Social Welfare Law Review

Positive rights, as a concept, are nothing new. Though they may not have always had such a deceptively unequivocal name, positive rights have existed in various forms and mediums throughout history. They've been utilized, underutilized, and, in some cases, outright ignored. At their core, positive rights are the imposition of an obligation upon the state to fulfill some declared right or benefit. One basis for this imposition is that because citizens give up certain rights by being parties to the "social contract," they should be entitled to certain positive protections guaranteed by the state created by way of said "contract." …

Addressing The Opioid Crisis In The United States And Modeling Its Proposed Interventions, Liza Eubanks

Honors Program Theses

A novel application of compartmental modeling is used to quantitatively study the impact of call centers on influencing an individual’s mindset as they begin or attempt to recover from opioid addiction. The opioid epidemic in the United States has affected millions of Americans, especially in West Virginia. This project studies the effectiveness of call centers in increasing the rate of recovery from opioid abuse. An active response is characterized by an open mindset and acceptance of help from others, while a passive response is defined by a closed mindset and an unwillingness to believe in the real possibility of recovery. …

The Antibacterial Efficacy Of Silver (I) Cyanoximates Against Streptococcus Mutans Ua159 Biofilm Growth And Infection In Galleria Mellonella Larvae, Jill Hughes

Honors Program Theses

Streptococcus mutans is the known etiological agent of dental caries. S. mutans’ virulence factors, namely biofilm formation and lactic acid fermentation, contribute to its pathogenic behavior within the oral cavity. Biofilms are thick, antibiotically resistant communities of bacteria that are much more difficult to treat than planktonic or free-floating bacteria. Continued misuse of antibiotics against dynamic communities, like biofilms, has led to increased research on non-antibiotic alternatives. Amongst these alternatives, there are silver and silver-based compounds. Silver is commonly incorporated into medicine due to its inhibitory and bactericidal effects and antibacterial properties. Silver (I) cyanoximates have demonstrated promising antibacterial activity …

Associations Between Socioecological Factors And Breastfeeding Duration Among Obese Mothers In Mississippi, Maria Mercedes Miranda Porter

Walden Dissertations and Doctoral Studies

There is a growing obesity pandemic in the United States. Low breastfeeding duration rates and socioecological factors lead to obesity in the most southern states. Overweight and obese breastfeeding mothers have not been primarily studied. There is mixed information regarding duration of breastfeeding, BMI, and heart health, as well as a lack of quantitative analyses involving reducing obesity rates in mother-child dyads. The purpose of this quantitative cross-sectional study was to investigate whether there were any associations between breastfeeding duration and BMI, heart health problems, breastfeeding support, and eating and exercise among Mississippi overweight and obese postpartum women based on …

Straight From The Coyote’S Mouth: Genetic Identification Of Prey Through Oral Swabs Of Predators, Julie K. Young, Amanda M. Mast, James A. Walton, Torrey Rodgers, Antionette J. Piaggio, Daniel R. Taylor, Karen E. Mock

United States Department of Agriculture Wildlife Services: Staff Publications

Human-carnivore conflicts often involve the depredation of domestic livestock. These depredation events are rarely observed, yet mitigation typically involves identifying the species or individual involved for removal or relocation. We tested a molecular method to identify individuals involved in depredation events using mouth swabs to determine if prey DNA could be detected, and for how long. We fed mule deer Odocoileus hemionus meat to captive coyotes Canis latrans and swabbed their mouths at five predetermined intervals between 2–72 h after consumption of the deer meat. We assessed two different molecular forensic methods to analyze the saliva swabs: qPCR for species …

United States Department of Agriculture Wildlife Services: Staff Publications

Wild pigs (Sus scrofa) are one of the most successful invasive species globally and are often implicated in agricultural damage. This damage is expected to increase as ranges of wild pigs expand, impacting the human food supply and increasing costs of food production. Our objective was to evaluate movement behaviors of wild pigs relative to resource availability and landscape features in an agriculture-dominated landscape, with a goal of informing management practices for reducing damage to corn. We monitored hourly movements of adult wild pigs relative to corn crops using GPS collars during the 2019 and 2020 growing seasons (Feb–Sept) in …

Burmese pythons (Python molurus bivittatus) are native to southeastern Asia, however, there is an established invasive population inhabiting much of southern Florida throughout the Greater Everglades Ecosystem. Pythons have severely impacted native species and ecosystems in Florida and represent one of the most intractable invasive-species management issues across the globe. The difficulty stems from a unique combination of inaccessible habitat and the cryptic and resilient nature of pythons that thrive in the subtropical environment of southern Florida, rendering them extremely challenging to detect. Here we provide a comprehensive review and synthesis of the science relevant to managing invasive …

Effects Of Corn Supplementation On Serum And Muscle Microrna Profiles In Horses, Clarissa Carver, Jason E. Bruemmer, Stephen Coleman, Gabriele Landolt, Tanja Hess

United States Department of Agriculture Wildlife Services: Staff Publications

Laminitis associated with equine metabolic syndrome causes significant economic losses in the equine industry. Diets high in non-structural carbohydrates (NSC) have been linked to insulin resistance and laminitis in horses. Nutrigenomic studies analyzing the interaction of diets high in NSCs and gene expression regulating endogenous microRNAs (miRNA) are rare. This study's objectives were to determine whether miRNAs from dietary corn can be detected in equine serum and muscle and its impacts on endogenous miRNA. Twelve mares were blocked by age, body condition score, and weight and assigned to a control (mixed legume grass hay diet) and a mixed legume hay …

Using Drones To Detect And Quantify Wild Pig Damage And Yield Loss In Corn Fields Throughout Plant Growth Stages, Bethany A. Friesenhahn, Lori D. Massey, Randy W. Deyoung, Michael J. Cherry, Justin W. Fischer, Nathan P. Snow, Kurt C. Vercauteren, Humberto L. Perotto‐Baldivieso

United States Department of Agriculture Wildlife Services: Staff Publications

Presently, there are an estimated 6.9 million wild pigs (Sus scrofa) in the U.S., which cause over US$1 billion in damage to agriculture, environmental impacts, and control costs. However, estimates of damage have varied widely, creating a need for standardized monitoring and a method to accurately estimate the economic costs of direct wild pig damage to agriculture. The goal of our study was to integrate remotely sensed imagery from drones and crop harvest data to quantify wild pig damage in corn fields. We used drones with natural color (red, green, blue) cameras to monitor corn fields at different …

Intracellular Diversity Of Wnv Within Circulating Avian Peripheral Blood Mononuclear Cells Reveals Host-Dependent Patterns Of Polyinfection, Dalit Talmi-Frank, Alex D. Byas, Reyes Murrieta, James Weger-Lucarelli, Claudia Rückert, Emily N. Gallichotte, Janna A. Yoshimoto, Chris Allen, Angela M. Bosco-Lauth, Barbara Graham, Todd A. Felix, Aaron C. Brault, Gregory D. Ebel

United States Department of Agriculture Wildlife Services: Staff Publications

Arthropod-borne virus (arbovirus) populations exist as mutant swarms that are maintained between arthropods and vertebrates. West Nile virus (WNV) population dynamics are host-dependent. In American crows, purifying selection is weak and population diversity is high compared to American robins, which have 100- to 1000-fold lower viremia. WNV passed in robins leads to fitness gains, whereas that passed in crows does not. Therefore, we tested the hypothesis that high crow viremia allows for higher genetic diversity within individual avian peripheral blood mononuclear cells (PBMCs), reasoning that this could have produced the previously observed hostspecific differences in genetic diversity and fitness. Specifically, …

Investigating Nocturnal Uas Treatments In An Applied Context To Prevent Gulls From Nesting On Rooftops, Morgan Pfeiffer, Craig K. Pullins, Scott F. Beckerman, Joshua L. Hoblet, Brad Blackwell

United States Department of Agriculture Wildlife Services: Staff Publications

Ring‐billed (Larus delawarensis) and herring (L. argentatus) gulls are numerous and widespread in North America. These gulls rank among the top 9 species for risk of bird‐aircraft collisions (hereafter strikes). The ubiquitous presence of gulls in urban coastal environments, including rooftop nesting behavior, are factors impacting strike risk. Our purpose was to assess gull response to a small uncrewed aircraft system (UAS) in hazing flights at night during the nest‐building phase. We hypothesized that nocturnal UAS operation, like nocturnal predator disturbance, might reduce gull numbers and, thus, strike risk to aircraft. In spring 2021, we conducted …

Urbanization Influences Spatiotemporal Patterns Of Roost Site Selection By Black Vultures And Turkey Vultures, Jacob E. Hill, Kenneth F. Kellner, Amanda E. Holland, Bryan M. Kluever, Morgan B. Pfeiffer, Travis L. Devault, Jerrold L. Belant

United States Department of Agriculture Wildlife Services: Staff Publications

Roost locations can be an important contributor to vulture conflicts with humans, but factors influencing roost-site selection at a landscape level remain largely unexplored. Further, there has been little research comparing how these factors vary between nocturnal and diurnal roosting sites. We used remote cameras to document daily variation in vulture use of 21 roosts (20 communication/water towers and 1 natural roost) near Beaufort, South Carolina, USA from October 2019–August 2020. Numbers of vultures on roosts increased with decreasing urban cover and with greater distance to water, but were not influenced by habitat fragmentation or elevation. Roosts surrounded by greater …

Loy, Rachael Birn, Bryan Buss, Matthew Donahue, Todd Nordeen, Kylie Sinclair, Luke Meduna, Bruce Brodersen, John Dustin Loy

School of Veterinary and Biomedical Sciences: Faculty Publications

Disease surveillance testing for emerging zoonotic pathogens in wildlife is a key component in understanding the epidemiology of these agents and potential risk to human populations. Recent emergence of SARS-CoV-2 in humans, and subsequent detection of this virus in wildlife, highlights the need for developing new One Health surveillance strategies. We used lymph node exudate, a sample type that is routinely collected in hunter-harvested white-tailed deer (WTD, Odocoileus virginianus) for surveillance of chronic wasting disease, to assess anti-SARS-CoV-2 neutralizing antibodies. A total of 132 pairs of retropharyngeal lymph nodes collected from Nebraska WTD harvested in Nebraska, US, in 2019 …

Advancing Racial Justice Through Civil And Criminal Academic Medical-Legal Partnerships, Yael Cannon, Vida Johnson

Georgetown Law Faculty Publications and Other Works

The medical-legal partnership (MLP) model, which brings attorneys and healthcare partners together to remove legal barriers to health, is a growing approach to addressing unmet civil legal needs. But MLPs are less prevalent in criminal defense settings, where they also have the potential to advance both health and legal justice. In fact, grave racial health inequities are deeply intertwined with both civil and criminal injustice. In both spheres, health justice is racial justice. Building on the experiences of the authors in their respective civil and criminal law school clinics at Georgetown University in Washington, D.C., this Article argues that academic …

Ccl2 Suppression In Lewis Lung Carcinoma Model Enhances Host Survival And Immune Response In The Tumor Microenvironment, Nivedita Biswas

Theses and Dissertations

CCL2, a chemokine also referred to as monocyte chemoattractant protein 1 (MCP-1) and small inducible cytokine A, is chemotactic for monocytes. CCL2-induced recruitment of CCR2+Ly6C(hi) monocytes increases vascular permeability CCR2+ endothelium aiding the escape and migration of tumor cells. CCL2 is produced by cancers of varied immunogenicity and augments tumor proliferation and metastasis. Elevated CCL2 expression by tumor cells is linked to poor prognosis.We have previously shown that two bacterially derived superantigens, Staphylococcal enterotoxin G and I (SEG/SEI) stimulate large numbers of T cells in an antigen-independent fashion and promote enhanced survival in the poorly immunogenic B16-F10 melanoma model. Conversely, …

Acaricidal Activity Of The Orally Administered Isoxazoline Drugs (Lotilaner, Fluralaner, And Afoxolaner) In White-Footed Mice Against Larval Ticks, Emily Marie Gisi

Theses and Dissertations

Lyme disease, caused by Borrelia burgdorferi, is currently the most prevalent vector borne disease in North America. With the CDC estimating almost 500,000 new cases every year, methods are needed to control the vector, the black legged tick (Ixodes scapularis). Like other tick-borne diseases, Lyme disease is zoonotic and involves tick parasitism on rodent reservoirs in the wild. The main reservoir host of Lyme disease is the white-footed mouse (Peromyscus leucopus). This study aims to explore the effectiveness of a reservoir targeted control approach by the treatment of white-footed mice with oral isoxazoline class drugs. …

Assessing Neuropsychological Changes Post Covid-19 Infection Using The Global Neuropsychological Assessment, Jeremy M. Raines

Theses and Dissertations

COVID-19 is characterized by a respiratory syndrome with severity ranging from mild upper respiratory tract illness to severe interstitial pneumonia and acute respiratory distress syndrome. Although physical symptoms are most common in those infected with COVID-19, patients may present with several neuropsychiatric sequelae caused by direct central nervous system infection, neuroinflammation, and/or prolonged hypoxia encephalitis. Though extent literature on COVID-19 related cognitive decline is still in its infancy, it has been suggested neurological impairment is most common in those with severe symptom presentation, requiring hospitalization and among those who have experienced hypoxic events.

Il-27 Negatively Impacts Immunity Developed Following Bcg Administration, Shelby D. Bradford

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mycobacterium tuberculosis (Mtb) is the causative agent of tuberculosis (TB), a predominantly respiratory pathogen responsible for over ten million infections and one million deaths last year. Despite it being a primary objective of the World Health Organization (WHO) for several decades to irradicate TB, progress toward this objective has fallen short of the 2020 target to end TB by 2035. Meeting this goal will require advancements in diagnostic tools, education, healthcare access, and treatments and preventatives. Regarding prevention, the primary tool for this strategy is through vaccination. Currently, the only licensed vaccine for protection against TB is the century old …

Optimizing Sample Collection And Data Interpretation For Effective Wastewater-Based Epidemiology In Combined Sewer Systems, Christopher Allen Anderson

Graduate Theses, Dissertations, and Problem Reports (ETD)

COVID-19 has spurred growth in the science surrounding wastewater-based epidemiology (WBE) pertaining to the detection of severe acute respiratory virus 2 (SARS-CoV-2) in waste streams as an early warning signal for public health. However, the highly variable wastewater environment has made it difficult to standardize an approach for sampling and analysis, especially in locations using combined sewer infrastructure. This study addresses knowledge gaps of WBE via three specific aims: (1) to compare diurnal fluctuations of SARS-CoV-2 and the human fecal indicator, pepper mild mottle virus (PMMoV) in wastewater treatment plant (WWTP) influent samples collected during dry versus wet weather conditions; …

Association Of Income, Education, Employment And Covid-19 Mortality In Brazil, Marcelina Machado

Walden Dissertations and Doctoral Studies

The increased mortality rates from COVID-19 in Brazil have adversely affectedvulnerable populations and placed a severe burden on its public health system as compared to other nations. Focusing on socioeconomic status as a risk factor in this retrospective cohort study, I investigated the association between Brazilian COVID-19 mortality rate, income, school enrollment rate, and employment rate after controlling for the demographics and immunization rate. This is an important issue as an increase in incidence and mortality rates affects how governmental and public health leaders can effectively control and prevent disease spread. Using the fundamental causes of disease theory as the …

Generation Of Chimeric Rhinoviruses Presenting Sars-Cov-2 Broadly Neutralizing Epitopes And Their Antigenicity Characterization, Danish Ansari

Biotechnology Theses

The global COVID pandemic is not yet fully under control as there were over 21 million new cases of SARS-CoV-2 infections and over 50,000 deaths globally as of January of 2022. A heavily mutated variant of concern, Omicron is responsible for most of these cases which demands an urgency for a new vaccine. NIH reports over 180 vaccine candidates that use various strategies currently in development. However, a recurring concern with these vaccines is that the continuous viral mutations decrease the efficacy of vaccines. Therefore, we proposed to construct a human rhinovirus (HRV) based chimeric virus containing highly conserved, broadly …

Increasing Hepatitis C Virus Screening In A Community Health Center : A Clinical Practice Change Initiative, Chassity B. Greer

Doctor of Nursing Practice (DNP)

The Hepatitis C virus is recognized worldwide as a public health concern. Despite the omnipresence of the condition, many individuals are oblivious to its presence owing to its asymptomatic nature and poor testing rates. This project evaluated the effectiveness of an evidence-based hepatitis C virus screening protocol to improve hepatitis C virus screening and testing among adult patients utilizing a community health center in North Mississippi. The project was designed as a clinical practice change with three anticipated outcomes following protocol implementation: increased screening rates (for patients), increased testing rates (among providers), and provider adherence to the screening and testing …
