Understanding The Operations And Decision-Making Of Cow-Calf Farmers In Northwest Arkansas, Clayton Weyl

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Societal pressure on farmers has become a more central part of the rhetoric surrounding livestock production. This study includes farmers in the discourse on the rhetoric surrounding climate change via interviews and simulations tailored to their operation. Previous research has addressed regenerative agricultural practices and conditions that influence farmer decision-making, but little research has analyzed decision-making in tandem with environmental practices. The literature reveals that cow-calf producer decision-making is influenced by their reliance on cattle as an income source, and farmers overall choose climate-friendly practices based on their perceptions about climate change. The goal of this research was to gather …

Closed-Loop, Recyclable Plastics From Ethyl Cyanoacrylate, Allison Joy Christy

Boise State University Theses and Dissertations

Ethyl cyanoacrylate, commonly known as super glue, has held a prominent role as an adhesive for decades due to its propensity to rapidly polymerize into poly(ethyl cyanoacrylate) (PECA) under ambient conditions. Ethyl cyanoacrylate monomers and their resulting PECA polymers are bio-friendly, which has allowed them to be used as medical adhesives and to be applied to drug delivery systems. However, PECA has not been used as a plastic material due to the perceived difficulty of handling the ethyl cyanoacrylate monomer. Here, we present a novel PECA plastic that displays thermal stability and tensile strength values that are comparable to atactic …

Determining The Effect Of Absorbents And Soybean Systems On Pfas Precursor Transformation, Tamia Wellington

Biological Sciences

PFAS (Per- and polyfluoroalkyl substances) refers to a class of chemicals that consist of long-chains of carbon bonded to fluorine. These are chemicals that have many industrial uses, from cosmetics to industrial fire-fighting foam. Since PFAS is so widely used and available, it has become increasingly present in water and soil, resulting in its uptake and bioaccumulation in plants. This study focused on the impacts of powdered activated carbon (PAC) and montmorillonite on the PFOS precursor N-ethyl perfluorooctane sulfonamido acetic acid (N-EtFOSAA), in soil, and in plants grown in that soil. This study focused on spiking soil with PFAS chemicals, …

Quantification Of Fibrosis And Infiltrates In The Salivary Gland, Nikhita Kumar

Biological Sciences

Fibrosis is characterized by the excessive buildup of extracellular matrix components (ECM) in tissues and organs in response to injury, chronic inflammation, auto immune disorders, and genetic alterations. Non-obese diabetic mice (NOD) are a model for Sjögren’s Syndrome. We hypothesize that NOD mice, which start to develop Sjögren’s-like disease at approximately 12 weeks of age are suffering from hyposalivation at least in part due to fibrosis of the submandibular salivary glands (SMGs). Fibrosis refers to the over-production of extracellular matrix proteins in the connective tissue compartment. To test this hypothesis 16-week-old mice were treated with either the fibrosis inhibitor Nintedanib …

Improvement Of Depressive-Like Behaviors In Hemi-Parkinsonian Rats With Non-Invasive Peripheral Focused Ultrasound Modulation, Hudy Berger

Biological Sciences

Parkinson’s disease (PD) is a chronic and progressive neurodegenerative disease with marked loss of dopaminergic neurons in the substantia nigra pars compacta (SNc). In PD, there are motor and non-motor symptoms. Depression, a non-motor symptom, is seen in 40% of the patients with PD which decreases their quality of life. For treatment-resistant depression, vagus nerve stimulation (VNS) has been shown to improve depression. Here, non-invasive focused ultrasound (FUS) is investigated as a therapeutic to improve depression-like behavior by targeting the celiac plexus since it is innervated by the vagus nerve. FUS was chosen due to its parallel mechanism to VNS. …

Fatty Females And Muscular Males: Investigating Human Sexual Dimorphism Across The Upper And Lower Skeleton, Brooklin Edwards

Anthropology Undergraduate Honors Theses

The sexual dimorphism profile of human body composition produces a unique pattern. Compared to other primates, humans have a mild size dimorphism; however, human males have a particularly muscular upper body and human females have a permanent fatty composition. These findings have resulted in varying interpretations related to sexual selection, mating systems, and male competition. Using humerus and femur measurements collected from 9 primate species, we investigated how the pronounced sexually dimorphic tissue composition of humans influences skeletal elements compared to the other primates. We hypothesized that over the course of human evolution, human females developed a body composition that …

Humanizing History: Applying Media Storytelling To Lived Experiences, Benjamin Goeser

Theses/Capstones/Creative Projects

This creative project explores the tendency of individuals to avoid or alter deemed unfavorable, unflattering, or simply humiliating traits or actions in their written and spoken personal stories. Such choices come from fear and pressure to present oneself in a more perfected state for others to “like” rather than a human state for audiences to relate to and learn from. Through a series of written personal accounts to air on UNO’s college radio station and website MavRadio.FM, the project brings attention to habits of human nature more likely to remain unspoken. The goal is to encourage the sharing of …

Correlation Between Stress Coping Styles And Genetic Variation In The Adenosine Pathway Of Zebrafish, Sydney Klucas

Theses/Capstones/Creative Projects

Anxiety is a common mental disorder and is caused in part by dysregulation of neurotransmitter systems. Specifically, the adenosine pathway has been correlated with anxiety disorders, but it is not yet known if genetic differences in this pathway are responsible for anxiety-related behavior. In this study, I used bioinformatic analyses (EdgeR and WGCNA) to investigate an RNA-sequencing dataset to assess differences in differential gene expression and gene co-expression networks within the adenosine pathway of zebrafish with different stress coping styles. These analyses included three brain regions: basolateral amygdala, hippocampus, and habenula. The differential gene expression analysis demonstrated that the adenosine …

Investigating Novel Chemotherapeutics Against The Parasite Toxoplasma Gondii, Braydon Dreher

Theses/Capstones/Creative Projects

Toxoplasma gondii, an intracellular protozoan, is a globally prevalent parasite due to the infectivity of T. gondii with nearly 2.5 billion people affected worldwide. Toxoplasma gondii can cause toxoplasmosis, which is a disease acquired through the consumption of undercooked meat or found in the feces of felines, and often leads to profound neuropathology and potentially death. Currently, acute toxoplasmosis is treated with pyrimethamine and sulfadiazine, which is a combination of an antiprotozoal and a sulfonamide. This combination of drugs directly targets the acute stage of infection but has failed to eliminate or impact the chronic carriage of bradyzoites while …

Airline Quality Rating 2023, Brent D. Bowen, Dean E. Headley

Is Hindsight 20/20? Reconsidering Popular Perceptions Of Civil War Surgeons, Miller Bacon

History Undergraduate Honors Theses

This paper provides a cursory examination of the history and truth of the modern “butcher” stereotype associated with Civil War surgeons. Beginning with a review of modern examples of the stereotype in cinema, educational materials, children’s literature, and academic literature, this thesis further provides a detailed historical analysis of the source of this stereotype in the nineteenth century. This analysis completes the cultural analysis present within the paper by demonstrating the presence of the “butcher” stereotype in Civil War era newspapers and literature.

Finally, after the cultural analysis of the modern stereotype and its historical roots in the nineteenth century, …

Stories From The Negative Spaces: United States V. Thind And The Narrative Of (Non)Whiteness, Joy Kanwar

Mercer Law Review

In the years following September 11, 2001, hate crimes and violent incidents against Sikh people in America rose dramatically. Most of these incidents involved individuals who targeted Sikh people—often men—because of their turbans and beards, which the attackers conflated with their own imagined versions of “9/11 terrorists.” Although the Sikh faith had no relationship to whom these attackers thought they were assaulting, very often someone they believed to be from the Islamic faith, the “visual” told the story—the victim was an outsider, someone who did not belong here and someone who was dangerous for America.

One particularly poignant moment resonated …

Digital Masculinity: An Analysis Of How Masculine Values Are Manifested In Online Spaces, Catherine Thompson

Honors Projects

In this research paper, I utilize previous research to demonstrate how the history of masculinity in America impacts views of social hierarchy in gendered spaces online. I describe how hegemonic masculinity affects how men view themselves and others to understand why men’s online groups like incels, pick-up artists, men’s rights activists, 4chan, and 8chan develop and thrive by providing men with groups where they can demonstrate hegemonic masculinity to other men through degrading women. Using this framework, I use a binary logistic regression model to quantify the relationship between men’s opinions surrounding internet behaviors and attitudes towards the internet with …

Effect Of Temperature On The Microbiome Of A Laboratory-Reared Colony Of Haemaphysalis Longicornis Ticks, Brianna L. Mitchell

Honors Theses

Haemaphysalis longicornis ticks are invasive to the United States with potential to transmit several tick-borne pathogens that are native to the United States. Based on existing locations of H. longicornis in its native regions in Asia, as well as its invasive populations that are established in the United States, several geographic range prediction models have been produced to help understand future range expansion and distribution of this invasive tick in North America. Unfortunately, these models do not all agree and there is uncertainty associated with the potential geographic range expansion of H. longicornis ticks in North America. Climate can affect …

Pirna Expression In The Tube Feet Of Lytechinus Variegatus, Reagan Milliet

Honors Theses

Tissue regeneration is an area of research with implications for medicine and animal health. While nearly all living multi-cellular organisms are capable of regeneration, there are major differences in the animal kingdom. Some organisms are capable of regenerating virtually every cell in their bodies. In hopes of engineering tissue regeneration for medical applications, the mechanisms by which organisms regenerate are being widely investigated. To better understand regeneration, the role of P-element Induced WImpy testis (PIWI) proteins are being evaluated. In collaboration with PIWIinteracting RNAs (piRNAs), PIWI proteins have been proven instrumental to transposon silencing and maintenance of the genome in …

A Case Study On Examining Systemic African American Poverty In Caddo Parish And Bossier Parish, Louisiana, Stephen Pinkney

Dissertations (2016-Present)

There are many states, counties, and cities in the United States of America where people do not have access to basic necessities such as food, housing, proper medical facilities, access to schools, and ready or no transportation, etc. The reason for this situation is due to the issue of poverty. Poverty is an unacceptably low-standard way of life that is a complex human phenomenon. It has multiple causes, manifestations, and dimensions. (Odhiambo, Omiti, Muthaka, 2005) Caddo Parish, Louisiana, is such a place that has high poverty among Black people. The population of African American people in Caddo Parish is larger …

Qualitative And Quantitative Analysis Of Cannabinoids In Commercially Available Hemp-Infused Oils By Hplc And Complementary Analytical Methods, Gina Delmonache

Forensic Science Master's Projects

For decades, cannabis consumption has remained one of the most controversial topics of discussion in both science and law. However, Cannabis sativa, from which both hemp and marijuana are derived, has served as an essential component of medicine, industry, and recreation for centuries. Approximately 500 compounds have been identified from cannabis alone, and only around 66 are termed cannabinoids which account for the majority of research on the substance. The major cannabinoid constituents include delta 9-tetrahydrocannabinol (delta 9-THC), responsible for the psychoactive effects of cannabis, in addition to, cannabidiol (CBD), tetrahydrocannbinolic acid (THCA), cannbidolic acid (CBDA), cannbigerol (CBG), …

Matrix assisted laser desorption/ionization imaging has greatly improved our understanding of spatial biology, however a robust bioinformatic pipeline for data analysis is lacking. Here, we demonstrate the application of high- dimensionality reduction/spatial clustering and histopathological annotation of matrix assisted laser desorption/ionization imaging datasets to assess tissue metabolic heterogeneity in human lung diseases. Using metabolic features identified from this pipeline, we hypothesize that metabolic channeling between glycogen and N-linked glycans is a critical metabolic process favoring pulmonary fibrosis progression. To test our hypothesis, we induced pulmonary fibrosis in two different mouse models with lysosomal glycogen utilization deficiency. Both mouse models displayed …

Science, Community, And Culture: A Holistic Approach To Ecological Research And Education, Laura Whipple

All NMU Master's Theses

Global biodiversity has declined at an alarming rate over the past century as a result of many complex human-induced environmental changes. Standardized surveys have historically been used to identify drivers of species declines, but such studies are often resource-intensive, resulting in significant spatial and temporal data gaps when researchers lack the resources necessary to maintain such studies. One promising solution for overcoming gaps in standardized studies is the integration of species observations by community members (e.g., community science). Along with improving modeling techniques to address biodiversity declines, the education of future ecologists on the importance of Indigenous ecological knowledge, robust …

Trends In Nestling Body Size In A Declining Population Of American Kestrels, Kristina M. Ollo

Theses, Dissertations and Culminating Projects

American Kestrels (Falco sparverius) are small falcons that feed primarily on large insects but also small mammals and birds. During recent decades kestrel populations have been declining in North America, for reasons still unknown. One plausible explanation is that nestlings are becoming malnourished over the years from lack of food resources and are fledging at smaller sizes. Fledging at a smaller size puts kestrel nestlings at greater risk of post-fledging mortality due to starvation or predation. Here we examined long-term trends in the morphological development of American Kestrel nestlings to see if there have been any significant changes over time. …
