The World Health Organization has classified childhood obesity as one of the most serious public health concerns in the world. Obesity is known to have detrimental health consequences and be a risk for comorbidities. On top of the consequences of obesity already seen in young children at school, a lack of health education interventions in many elementary schools remains a significant health disparity. Anatomy Academy (AA) is a seven-week curriculum designed to educate children about their bodies and the importance of gaining and maintaining a healthy lifestyle. The purpose of this service-learning project was to educate elementary school students in …


The Impact Of Attachment And Optimism On Delinquency, Kaylee Dawn Faria May 2023

The Impact Of Attachment And Optimism On Delinquency, Kaylee Dawn Faria

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study is to assess if justice-involved juveniles’ optimism toward future prospects mediates the relationship between parental and peer attachment and the likelihood of future delinquency. Theory and prior research support the argument that there is a negative relationship between parental and peer attachment and delinquency, and a negative relationship between optimism and delinquency. This study attempts to expand on this research by exploring whether parental and peer attachments influence delinquency through their influence on optimism for future prospects. This study utilizes data from the Pathways to Desistance Study, a panel study of seriously justice-involved youth, to …


Joint Constraints On Kepler-36 From Kepler And New Keck-Hires Data, Nicholas Juliano May 2023

Joint Constraints On Kepler-36 From Kepler And New Keck-Hires Data, Nicholas Juliano

UNLV Theses, Dissertations, Professional Papers, and Capstones

I analyze new HIRES Radial Velocity (RV) data in conjunction with transit mid-times and uncertainties from the full 17 quarters of Kepler data to reassess the orbital parameters of the Kepler-36 system. Six additional RV measurements were taken by the Keck-HIRES spectrograph from September 21, 2021 to October 11, 2021. I carry out a differential evolution Markov Chain Monte Carlo-based (DEMCMC) analysis to infer improved orbital elements for the two known planets in the system. Leveraging additional information provided by the new RV measurements, I extend this DEMCMC analysis to a possible three-planet configuration. I explore the likelihood of a …

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation utilized a mixed-methods approach which illustrated the potential benefits of HAI in addressing human health concerns, focusing on specific populations within the United States. The chapters presented in this dissertation provide insight into the complex relationships between humans and animals, including the roles of companion animals in promoting human well-being. Chapter three surveys 234 Americans observing COVID-19 stay at home isolation orders and findings suggest that the presence of companion animals alleviates stress and isolation by providing attachment figures and activities on which to focus one’s energy. Chapter four explores women’s oxytocin levels after interacting with their cat …


Examining Reflexive Communication Following A Break In Alcohol Abstinence, Lynda Kay Maxfield May 2023

Examining Reflexive Communication Following A Break In Alcohol Abstinence, Lynda Kay Maxfield

UNLV Theses, Dissertations, Professional Papers, and Capstones

Over 107 million individuals are thought to have alcohol use disorder (AUD) (Ritchie & Roser, 2018). Discontinuing drinking can be difficult, but social support is thought to promote sobriety efforts. The r/stopdrinking online public community supports such efforts. This study has two broad aims: (1) explore how resilience building might occur on r/stopdrinking among initial users disclosing an abstinence disruption and responses from other users; and, (2) explore possible relationships, within initial posts, between resilience and three other phenomena (i.e., trauma, stated views of Alcoholics Anonymous, statements reflecting the transtheoretical model’s ten processes of change; Prochaska & Prochaska, 2021). To …

Gender Differences In Internalizing Problems And Everyday Behaviors Associated With Executive Function In Children And Adolescents With Autism Spectrum Disorder, Hiroko Mullner

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Many children with autism spectrum disorder (ASD) experience internalizing problems, and there was evidence suggesting that poor executive function (EF) predicted their internalizing problems. However, this association was primarily found in studies with male children with ASD. Therefore, the present study aimed to investigate gender differences in internalizing problems and everyday EF in ASD children (age 5-15) and examined the associations between internalizing problems and everyday EF.Method: This study examined neuropsychological assessment data of ASD children without intellectual disability. The study consisted of two groups: 1. ASD boys (n = 44), 2. ASD girls (n = 15). The study …


Diving Into The Deep: A Mystical-Contemplative Leap Of Hope From The Pew, Lori A. Stanley May 2023

Diving Into The Deep: A Mystical-Contemplative Leap Of Hope From The Pew, Lori A. Stanley

Say Something Theological: The Student Journal of Theological Studies

This paper focuses on the intersection of the mystical and the contemplative by engaging The Collected Works of St. Teresa of Avila with Dr. Barbara A. Holmes’ Every Shut Eye Ain’t Sleep: The Inner Life During Slavery. The conversation reveals their perspectives on the role contemplative practices have in building and sustaining community. Contemplative prayer, like God, is no respecter of status or position and encounters souls where they are. The mystical-contemplative dimension of my paper is to see whether these two works in conversation would be able to address concerns I have about anti-black narratives in my present …


Saint Monica’S Model Of Catholic Excellence In Augustine’S Confessions, Caelan Mckamey May 2023

Saint Monica’S Model Of Catholic Excellence In Augustine’S Confessions, Caelan Mckamey

Say Something Theological: The Student Journal of Theological Studies

This paper discusses Saint Augustine’s presentation of his mother, Monica, as a model Catholic throughout his Confessions. Saint Augustine utilized individuals he encountered throughout his life as models of perfect Catholicism in an effort to provide resources for his medieval contemporaries to draw from throughout their own faith journeys. As a convert himself, Augustine drew holy inspiration from his mother, Saint Monica, as he searched for life’s purpose and God’s grace. He presents his mother throughout the first nine books of the Confessions as a human woman – trapped in a loveless marriage, filled with anxiety and fear, yet …


Is It A Requisite For A ‘Believer’ To Be Part Of The Formal/Institutional Church?, Dillon Cook May 2023

Is It A Requisite For A ‘Believer’ To Be Part Of The Formal/Institutional Church?, Dillon Cook

Say Something Theological: The Student Journal of Theological Studies

For the purposes of this paper, I attempt to wrestle with the question of whether or not it is a requisite for a “believer” (which turns out to be a loaded and ambiguous term) to be a part of a formal/institutional Christian Church. This is a difficult task to accomplish, and this, I admit. There is no way to answer this, truly with certainty. But Metaphysics are rarely grounded in “certainty.” This is true for many Christian Theological tasks as well. Nevertheless, this argument will be attempted by working with and off of the Black liberation theologian and philosopher, James …

“Redeeming The Religion” Of The Colonizer: Exploring Filipino Worship In The U.S., Gabrielle Poma

Say Something Theological: The Student Journal of Theological Studies

This paper aims to serve as an introduction to what the author considers a staple but often overlooked demographic in the pews of Catholic Churches in the United States: Filipinos and Filipino Americans. We begin with a brief overview of Filipino indigenous traditions, Spain’s colonization of the Philippines, and migration trends from the Philippines to the United States. We then explore how Filipino Catholics emerged from intimate devotional gatherings in households and hidden corners of their churches to assert their communities’ needs through parish leadership and civic engagement. In the public forum and thousands of miles from the Philippines, Filipinos …


Preparing Homogenous Composites Of Collagen And Cellulose Nanocrystals For Tissue Engineering Research, Zachary Stanley May 2023

Preparing Homogenous Composites Of Collagen And Cellulose Nanocrystals For Tissue Engineering Research, Zachary Stanley

Biological and Agricultural Engineering Undergraduate Honors Theses

Advancements in medicine and our understanding of stem cells have led to a greater emphasis on further developing research focused on tissue engineering. This research has led to the rise of both two-dimensional and three-dimensional scaffolds that can be utilized to repair bone, skin, vascular, and potentially even nervous tissue. One of the prominent compounds used in modern scaffolds is collagen-based hydrogels due to their low antigenicity and ability to provide structure to cells. There is potential to further improve upon this three-dimensional scaffold by incorporating cellulose nanocrystals (CNCs) into a composite hydrogel with collagen. The addition would increase the …

Analyzing Energy Use From Arkansas Public School Buildings, Oscar Morton

Biological and Agricultural Engineering Undergraduate Honors Theses

Energy is a key global resource in society and greenhouse gas (GHG) emissions related to the consumption of energy have detrimental effects on the planet. With energy consumption increasing, exponential population growth, and diminishing natural resources necessary for energy production, the relevance of energy efficiency is dramatically increasing. In this project, I analyzed energy usage data from a set of public school buildings from one school district in northwest Arkansas from 2018, before targeted energy efficiency practices were implemented, through 2022 to see if energy usage changed over this short period. The objectives of analyzing energy data were to determine …


Assessing Illegal Shooting Of Birds Along Power Lines, Eve C. Thomason May 2023

Assessing Illegal Shooting Of Birds Along Power Lines, Eve C. Thomason

Boise State University Theses and Dissertations

Birds found dead near power lines typically are assumed to have died from electrocution. However, birds die from many causes, and inaccurate diagnosis of cause of death undermines law enforcement, management, threat assessment, and mitigation. We used field and necropsy data from dead birds collected along 196 km of power lines in four western USA states in 2019 – 2022 to test the assumption that electrocution is the leading cause of death of birds on power lines. Of 175 birds with a known cause of death, 66% died from gunshot, whereas only 17% died from electrocution or by trauma. To …


Automating Pharmacokinetic Predictions In Artemisia, Celin Younan May 2023

Automating Pharmacokinetic Predictions In Artemisia, Celin Younan

Boise State University Theses and Dissertations

Pharmacokinetics (PK) is the time course of a compound in the body that is dependent on mechanisms of absorption, distribution, metabolism, and excretion or ADME. A thorough understanding of PK is essential to predict the consequences of organisms exposed to chemicals. In medicine, predictions of PK of drugs allows us to properly prescribe drug treatments. In toxicology, PK allows us to predict the potential exposure of environmental contaminants and how they may affect organisms at the time of exposure or in the future. Chemical ecology could benefit from computational predictions of PK to better understand which plants are consumed or …


Analysis And Implementation Of A New High-Buck Dc-Dc Converter With Interleaved Output Inductors And Soft Switching Capability, Sajad Ghabeli Sani, Mohamad Reza Banaei, Seyed Hossein Hosseini May 2023

Analysis And Implementation Of A New High-Buck Dc-Dc Converter With Interleaved Output Inductors And Soft Switching Capability, Sajad Ghabeli Sani, Mohamad Reza Banaei, Seyed Hossein Hosseini

Turkish Journal of Electrical Engineering and Computer Sciences

This paper proposes an innovative structure for DC-DC converters with high buck gain by using a lower number of elements. The converter provides highly efficient output power and an extended output voltage range. In addition, the distribution of output current between two inductors and the soft-switching capability of the power switches have made the converter suitable for applications that require high output current. All power switches accomplish the ZVZCS (zero-voltage and zero-current switching) condition with the aid of a small auxiliary inductor (Lx), which charges and discharges parallel capacitors of main switches to provide soft-switching conditions. Thus, the switching losses …

The earlier algorithms utilized classical image processing techniques where the implementations of machine learning and deep learning algorithms appeared with the developments in the artificial intelligence field as well as the computer hardware. In this study, a novel convolutional neural networks-based deep learning algorithm has been developed that detects counterfeit Turkish Lira banknotes and their denominations using the banknote images …


Understanding The Operations And Decision-Making Of Cow-Calf Farmers In Northwest Arkansas, Clayton Weyl May 2023

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 …


Foreign Ownership Of Agricultural Land In The United States: A Case Study Concerning The 2023 Grassroots Policy And Legislative Landscape, Mary Eichenberger May 2023

Foreign Ownership Of Agricultural Land In The United States: A Case Study Concerning The 2023 Grassroots Policy And Legislative Landscape, Mary Eichenberger

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Historically, foreign ownership of land in the United States has existed for centuries. Many state laws expressly allow for foreign ownership of agricultural land in their state. However, this study will find that a push to amend these laws has begun in recent years in state and federal legislatures. Grassroots member-focused agricultural organizations, representative of the agricultural community, have also seen a shift in member-developed policy. This shift is toward an attitude of concern and increased oversight of foreign land investment. From the data gathered, it can be inferred that public awareness in the agricultural community is increasing concerning foreign …


Closed-Loop, Recyclable Plastics From Ethyl Cyanoacrylate, Allison Joy Christy May 2023

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 May 2023

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 May 2023

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 May 2023

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. …


Progress Towards Peptide And Protein Synthesis Involving Thiol Moieties, Ryan Lo Chen May 2023

Progress Towards Peptide And Protein Synthesis Involving Thiol Moieties, Ryan Lo Chen

Biological Sciences

Polypeptides and proteins play crucial roles in biological systems, including enzymatic activity regulation, molecule transport, and cell and tissue structural support. Amino acids are the building blocks of peptides and proteins, and peptides can act as hormones, neurotransmitters, and enzymes. Proteins are made up of one or more polypeptide chains and have diverse functions such as catalyzing chemical reactions, transporting molecules, and providing structural support. Protein preparation can be done biologically by expression systems or isolation and purification from natural sources. While these methods have their advantages, they also have their shortcomings. Chemical synthesis is an alternative method that allows …

The Insurer Of Last Resort: Investigating A Federal Insurance Backstop For Catastrophic Cyber Incidents, Brianna Bace

Political Science

The demand for cyber insurance has accelerated in recent years due to the increased frequency and severity of cyber-attacks. The NotPeyta cyberattack, which spread to countries and systems across the globe and is estimated to have caused over $10 billion in damages, is one example. These kinds of catastrophic cyber incidents are causing insurers to raise premiums and tighten their policies, creating a significant gap in protection in the market. In response to this problem, the United States Treasury Department issued a Request for Comment regarding the potential for a federal insurance response to catastrophic cyber incidents. The aim of …


Are Right-Wing Populists And Right-Wing Populist Parties In America Buoyed By Mass Self-Deception?, Owen Herbert May 2023

Are Right-Wing Populists And Right-Wing Populist Parties In America Buoyed By Mass Self-Deception?, Owen Herbert

Political Science

The recent rise of right-wing populist candidates and parties in America and around the globe has (unsurprisingly) been associated with a concomitant growth in scholarship on the causes of individuals voting for right-wing populist candidates and joining the movements with which those candidates associate. Much of the scholarship in this area appeals to economics or culture as reasons why individuals side with right-wing populists or right-wing populist parties and movements. This thesis will begin by examining the significant literature in those two areas. Then, I will raise two questions that the literature has scarcely addressed: (1) What is the psychological …


U.S.-Russia Relationships: How Superpower Relations Affect Conflict Resolution, Julian Terris May 2023

U.S.-Russia Relationships: How Superpower Relations Affect Conflict Resolution, Julian Terris

Political Science

Russia and the United States struggle for power throughout the 20th and 21st century has imprinted itself on many current conflicts. While the post-war international order has focused on avoiding violent conflict, the inability of Russia and U.S. to cooperate has hindered the ability to create peace throughout these zones of conflict. This paper seeks to demonstrate how U.S. and Russian relations have influenced current conflicts as well as which policies they should adopt in order to help resolve conflicts in the future. It specifically analyses ideological, military and economic actions taken by both nations throughout the Ukrainian, …


The Scaling Method: Body Mass Reconstruction Of East African Hominins, Julianna Rose May 2023

The Scaling Method: Body Mass Reconstruction Of East African Hominins, Julianna Rose

Anthropology Undergraduate Honors Theses

This thesis details a series of novel methods developed to estimate body masses of hominin fossils using 3-D point cloud registration software. All analyses were conducted through 3-D modeling software that supported the remote study of five fossil femora from East Africa. The fossil computer models were repeatedly aligned with anatomically modern human femora to determine their scaling relationship with the objective of using the scaling factor of the human references to estimate the body mass of the fossils, on the basis of the femoral head breadth. Body mass estimates obtained through this technique were compared to estimates using more …


“Man, I Will Miss This Place”: An Ethnographic Account Of Place-Making On Dickson Street Through Men’S Bathroom Graffiti, Ethan S. Brown May 2023

“Man, I Will Miss This Place”: An Ethnographic Account Of Place-Making On Dickson Street Through Men’S Bathroom Graffiti, Ethan S. Brown

Anthropology Undergraduate Honors Theses

Walking into a public bathroom, often we are faced with interesting, unique, and easily ignorable cases of residual humanity: bathroom graffiti. These writings, academically known as latrinalia, offer scholars a unique portrait of the people who form an immediate culture and community. By providing opportunities to produce individual and collective identities, local folklore, and contesting narratives of space, latrinalia allows authors to carve out personal or cultural place out of the impersonal materiality of space. Utilizing traditional methods of ethnographic fieldwork, latrinalia in the men’s bathrooms of three bars along the famed Dickson Street in Fayetteville, Arkansas is approached …


Fatty Females And Muscular Males: Investigating Human Sexual Dimorphism Across The Upper And Lower Skeleton, Brooklin Edwards May 2023

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 …
