The Impact Of Low Appendicular Skeletal Muscle Mass In The Development Of Insulin Resistance And Metabolic Syndrome: A Systematic Review Of The Literature, Ella Boston

The Eleanor Mann School of Nursing Undergraduate Honors Theses

Chronic conditions are the leading cause of death and disability. More specifically, cardio-metabolic disease is the number one cause of death worldwide. The tragedy and burden of disease is unrefuted; even more so, evidence indicates that realistic modifications of lifestyle can prevent most chronic disease. Metabolic syndrome and insulin resistance are leading risk factors in the development of cardio-metabolic disease. Presently, chronic disease is treated through symptomatic evaluation of risk. Reframing the lens of care through root cause evaluation is fundamental to optimizing patient outcomes. The purpose of this systematic review is to synthesize literature evaluating the impact of low …

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 …

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 …

The SARS-related coronavirus (SARS-rCoV) is a highly contagious virus that has raised significant worldwide health concerns. It caused outbreaks in 2002-2003 and more recently in 2019-2020 with SARS-CoV-2. SARS-CoV-2 is responsible for the COVID-19 pandemic, which has resulted in a significant global impact on health and the economy. The spike protein of the virus plays a critical role in its infectivity and transmission, and the receptor-binding domain (RBD) within the spike protein is of particular interest, as it is responsible for binding to the human angiotensin-converting enzyme 2 (ACE2) receptor. In this study, we used Molecular dynamics (MD) simulations to …

Buried Treasure: What Gold Mining In Guyana Means For Indigenous Peoples, Traditional Knowledge, And Sustainability, Adoette Vaughan

International and Global Studies Undergraduate Honors Theses

Guyana’s Indigenous population, known as Amerindians, suffer greatly due to their lack of land rights and mining that infiltrates their remote territory in the country’s interior. Gold is the most lucrative export for Guyana, accounting for 10% of its GDP. However, the economic benefits and environmental and social costs associated with the industry have not been distributed evenly. Substantial environmental and social harms due to mining plague Amerindian communities. Mining activity fells vast stretches of forest, disrupts water channels and drives erosion through dredging. Mercury, used for gold amalgamation, seeps into river channels, poisoning fish and those who rely on …

Women And Religion In The Mongol Empire, Karlie Barnett

History Undergraduate Honors Theses

Aspects of the Mongol Empire have been well studied in academia, but these analyses, like much of our recording and analysis of world history overall, have largely excluded women. This thesis seeks to contribute to the effort to restore women to Mongol history, focusing on how the relationship between Mongol women and religion impacted the development of the Mongol Empire and Eurasian religions during the thirteenth and fourteenth centuries. With a focus on elite women due to the nature of the sources, I draw upon historical chronicles, traveler accounts, artwork, and contributions from scholars in this field to assert that …

Influence Of Jesuit Linguistic Manipulation On Guaraní Gender Norms In Colonial Paraguay, Anna Rumpz

History Undergraduate Honors Theses

Language was just one of the ways that colonizers and natives had to interact in unfamiliar ways post-Columbus. Histories of colonization often emphasize the physically brutal aspects, such as disease, slavery, or warfare, but colonization is a holistically violent process that adversely impacts societies on multiple levels. In particular, this thesis focuses on the link between culture and language, with respect to Jesuit Spanish-Guaraní lexicons, as a framework to understand changes to gender roles and sexuality within the Jesuit missions of the early seventeenth century.

A Consumer's Guide To Greenwashing, Katie Fowler

Marketing Undergraduate Honors Theses

Over the past 37 years since the term greenwashing was coined, there have been sparse attempts to regulate this deceptive environmental marketing. The Federal Trade Commission (FTC) created its Guides for the Use of Environmental Marketing Claims, also known as the Green Guides, in 1992. The Guides have been revised on three separate occasions – 1996, 1998, and 2012 – in an attempt to remain relevant with the proliferation of environmental marketing claims and trends. However, the Guides were created as interpretive rules that do not give the FTC the authority to enforce the regulations unless they can prove that …

Existentialism And Creative Practice, Catherine Hudgens

School of Art Undergraduate Honors Theses

The creative process mimics the existentialist philosophy of human freedom and the responsibility to create one’s own meaning in life through an emphasis on invention, experimentation, and ceaseless becoming. Through my body of work, I examine the meaning-giving capacities of the viewer and creator as agents involved in a work of art. The sculptures, as well as found objects, have the power to illuminate the human circumstances they emerged from, while the process of making is also the process of learning, where objects can be used to understand ourselves and the world. Philosophical concepts can be accessed through art in …

Comprehensive Long- And Short- Read Sequencing Approaches To Screen The Mutational Landscape After Therapeutic Crispr-Editing For Duchenne Muscular Dystrophy, Mary Jia, Made Harumi Padmaswari, Landon Burcham, Shilpi Agrawal, Alexis Ivy, Abbey Bryan, Christopher E. Nelson

Biomedical Engineering Undergraduate Honors Theses

Duchenne muscular dystrophy (DMD) is an X-linked muscle wasting disease caused by mutations in the Dmd gene resulting in non-functional dystrophin. Adeno-associated virus (AAV)-mediated delivery of classical CRISPR systems resulting in double-stranded breaks (DSBs) has yielded promise as a curative DMD therapeutic. However, the consequences of AAV-CRISPR require more thorough characterization. PCR-enriched short-read amplicon sequencing at cut sites is the most common method of sequencing CRISPR editing, but PCR bias results in unreliable quantification of on-target edits. We analyze orthogonal long- and short-read sequencing approaches to screen the outcomes of CRISPR technologies at the DNA and RNA-level for DMD. We …

Effects Of Sow Vocalization And Scent On Complete Blood Cell Count During Early Weaning Period, Mason Paladino

Biological Sciences Undergraduate Honors Theses

Piglets are deprived of their sows’ touch, sound, and smell after weaning which results in biological stress. The present study investigated continuing exposure of sow vocalization and scent during the early weaning period on complete blood cell count. A total of 12 litters, 8 piglets (4 male and 4 female) per litter were selected at weaning and assigned to 1 of 4 experimental treatments: control, O (olfactory group with scent and no vocal stimulation), V (non-olfactory with vocal stimulation), VO (vocal stimulation and olfactory stimulation) as a 2x2 factorial arrangement. Vocal stimulation was emulated by an audio recording of the …

Effect Of Mating On Male Choosiness In Bicyclus Anynana, Ellie Hope Magera

Biological Sciences Undergraduate Honors Theses

Males mate multiply in many species, including butterflies, but little is known about whether the act of mating influences future male choosiness. We might expect mating to influence future preference, as previous studies have shown that pre-mating social experiences affect future male mate choice. To determine if initial male mate choice affects subsequent male mating decisions, we conducted behavioral assays using the subtropical nymphalid butterfly Bicyclus anynana. We tested three alternative hypotheses: 1) initial mating is a positive experience that strengthens male preference for the previously encountered phenotype; 2) males prefer mating with a different phenotype in their second …

Understanding The Role Of Heterodisulfide Reductase During Nitrogen Fixation By Methanosarcina Acetivorans, Grant Shelnut

Biological Sciences Undergraduate Honors Theses

Methanosarcina acetivorans is a methanogenic archaeon (methanogen) that is important for several processes in our biosphere. A feature of interest within this methanogen is the enzyme nitrogenase which catalyzes the reduction of unusable dinitrogen gas (N₂) into a usable form of nitrogen, ammonia (NH₃). How electrons are transferred within M. acetivorans to nitrogenase during N₂ reduction is unknown. Heterodisulfide reductase (Hdr) is a key enzyme known to reduce the electron carrier protein ferredoxin, which is a direct electron donor to nitrogenase in bacteria. I hypothesized that cytoplasmic HdrA2B2C2 functions in electron transfer to nitrogenase and …

Hormonal Control Of Osmoregulatory Proteins In The Intestine Of Atlantic Killifish (Fundulus Heteroclitus), Karma Hine

Biological Sciences Undergraduate Honors Theses

The Atlantic killifish (Fundulus heteroclitus) is a euryhaline fish, and thus able to maintain ionic and osmotic homeostasis in a wide range of salinities. When exposed to the dehydrating marine environment, the lost water is replenished through drinking seawater (SW) which is processed and absorbed in the intestine through the involvement of various cellular effectors. Intestinal water transport is osmotically driven by the active removal of NaCl from the gut lumen to the blood coupled to the precipitation of divalent Mg²⁺ and Ca²⁺ due to the secretion of bicarbonate. These processes allow for successive removal of …

For this project, a unit teaching plan was created to introduce students to the field of engineering, providing a foundation for their upper-level STEM classes, and encouraging them to consider engineering as a career in the future. …

Dental Microwear Of Miocene Primates From The Turkana Basin Of Northern Kenya, Leah K. Myerholtz

Graduate Theses and Dissertations

Comprehending the dietary patterns of Turkana Basin primates from the late Paleogene and early Neogene can contextualize the role of food choice in the evolution of higher primates in Africa. Dental Microwear Texture Analysis (DMTA) quantifies wear on the enamel of a tooth and can be used as a proxy to infer aspects of a taxon’s diet in the past. DMTA can provide insight into what specific animals in the past ate, rather than what they were capable of eating, and by extension, reflect food availability related to habitat preferences or environmental fluctuation. Here, primates from six Oligocene through Pliocene …

Ireland V. United States: Agricultural And Environmental Sustainability Policies, Lauryn O'Grady

Accounting Undergraduate Honors Theses

The United States and Ireland have varying practices to achieve similar objectives in regard to environmental sustainability. While the European Union has maintained and updated a uniform policy throughout its existence--the Common Agricultural Policy--the United States instead created short-term solutions to a long-term problem. Not only does the United States tend to solve issues in the short-term, the policies between agricultural production and environmental sustainability are not necessarily aligned or remotely relative to the other. While the United States’ new Global Food Security Strategy implements parts of both agricultural and environmental sustainability, much of the history was not based off …
