Children’S Social Judgments Of Others On The Basis Of Dialect-Specific Vocabulary, Madison Myers-Burg

Graduate Theses and Dissertations

Many studies suggest that young children prefer speakers who speak similarly to them. Children demonstrate social preferences for speakers of their own native language over speakers of a non-native language as well as for speakers of a familiar accent over speakers of an unfamiliar accent. Recent research suggests that young children will similarly show preference for speakers who use familiar dialect-specific vocabulary over speakers who use vocabulary specific to an unfamiliar dialect. The current study investigated potential motivations behind young children’s preferences for familiar dialect-specific vocabulary. Fifty participants ages fifty-one months to ninety-five months (Mage =72.6 months) viewed an animated …

Predicting The Likelihood And Scale Of Wildfires In California Using Meteorological And Vegetation Data, Matthew Walters

Graduate Theses and Dissertations

Wildfires have devastating ecological, environmental, economical, and public health impacts through the deterioration of water and air quality, CO2 emissions, property damage, and lung illnesses. The early detection and prevention of wildfires allow for the minimization of these risks. The use of Artificial Intelligence (AI) in wildfire detection and prediction has been highly researched as a tool to assist firefighters in stopping wildfires in its early stages. The three common wildfire prediction categories include image and video detection, behavior prediction, and susceptibility prediction. Data such as climate, weather, vegetation, satellite images, and historical wildfire data is most commonly used. Many …

“Young Adult Books Don’T Realize They Have That Power”: Reader Response To Ideology In Young Adult Dystopian Fiction, Zane Emīlija Sarma

Graduate Theses and Dissertations

The purpose of this research is to find out how readers interact with novels in the Young Adult dystopian genre. I will examine the ways in which readers resist the dominant patriarchal ideological discourses in the YA dystopian novel and how readers submit to this ideology. Through an interaction with the text, the reader produces oppositional, negotiated, or preferred meanings. I will argue that readers’ response to ideology in the YA dystopian novel is affected by their active participation in reader communities such as the Bookish community online.

YA dystopian fiction was highly popular in the early 2010s, but the …

Poultry Science Faculty Publications and Presentations

Heat stress (HS) is devastating to poultry production sustainability due its detrimental effects on performance, welfare, meat quality, and profitability. One of the most known negative effects of HS is feed intake depression, which is more pronounced in modern high-performing broilers compared to their ancestor unselected birds, yet the underlying molecular mechanisms are not fully defined. The present study aimed, therefore, to determine the hypothalamic expression of a newly involved pathway, hypoxia/oxygen homeostasis, in heat-stressed broiler-based research lines and jungle fowl. Three populations of broilers (slow growing ACRB developed in 1956, moderate growing 95RB from broilers available in 1995, and …

Examining The Invasion Of Bush Honeysuckle Through A Phylogenetic Analysis, Phoebe Bruffett

Biological Sciences Undergraduate Honors Theses

The mechanisms underlying the continual spread of invasive plants within their respective non-native ranges is a major focal point to invasion research. Many theories have been proposed to understand these invasions, each with different implications for the predicted range for invasive plants. Lonicera maackii provides an exceptional opportunity to examine the effectiveness of these theories to explain the trends of invasive plants. Lonicera maackii is native to eastern Asia, but has invaded much of the eastern United States, presenting a severe threat to the health of forest and other natural areas. Recent analysis of the climatic envelopes uncovered a significant …

Investigating The Potential Role For The Nervous System In Controlling Regeneration In Nematostella Vectensis, Kristen Malir

Biological Sciences Undergraduate Honors Theses

Nematostella vectensis is a marine sea animal that has become a model for developmental and evolutionary research. Included in the phylum Cnidaria, N. vectensis’ was chosen as the model for this research. Not only can this animal go through asexual and sexual reproduction, but it also has the ability to regenerate. Although much research has been put forth in an effort to understand regeneration better, much is still unknown. The underlying mechanisms of regeneration in Cnidaria are illusive; however, studies within vertebrates have shown the substantial role of the nervous system. The objective of this experiment is to test if …

The Synchronization Of Nocturnal Pollinator Behavior And Apple Flower Nectar Production, Madison Jennings

Biological Sciences Undergraduate Honors Theses

Insects perform an essential ecological service by facilitating the pollination of crops for food production worldwide. Recent declines in diurnal bee populations threaten food security and has led to growing concerns about existent pollination methods. Pollination contributions by native nocturnal insects have been documented to occur in a variety of systems, thought to be supported by the plant’s attractant and reward system. If this is the case, pollination of flowers by nocturnal vectors may be influenced by circadian cycles of nectar production and insect activity. To test this hypothesis, we recorded insect abundance of nocturnal pollinators periodically throughout the night …

Using Ai To Examine Nocturnal Moth Pollination, Conor Moriarty

Biological Sciences Undergraduate Honors Theses

The importance of insect-mediated agriculture cannot be understated especially in the wake of pollinator population declines. Most research of insect-mediated pollination is focused on diurnal pollinators like the honeybee (Apis mellifera). Deepening our understanding of how other pollinators, such as nocturnal pollinators, can benefit agriculture and ecosystems will be very important as honeybee populations decline. I explored nocturnal moth interactions with flowering apple flowers during their pollination season to better understand how these nocturnal pollinators interact with the plants. To accomplish this, I used a University of Arkansas farm area with a dedicated apple orchard. I gathered my raw data …

Relationship Between Pet And Human Separation Anxiety On Owners’ Anxiety And Physical Health, Noah Ross

Psychological Science Undergraduate Honors Theses

Pet ownership has always been thought to be beneficial, but some recent studies have not been consistent with this statement. A possible explanation for this is an unhealthy overdependence that pets and pet owners have developed as a result of the Coronavirus pandemic. In this paper, I examine whether separation anxiety from pets, people, and separation behavior of pets could be predictors of anxiety and physical health. The first prediction was that pet and non pet owners differed demographically. Also, it was hypothesized that separation anxiety from humans, separation anxiety from pets, but not pet separation behaviors predicted anxiety and …

Exploring The Effects Of Varied Land Use On Elemental Concentrations Within Streams, Logan Jennings

Biological and Agricultural Engineering Undergraduate Honors Theses

It is well documented that human activity influences the chemistry of surrounding waters. As such, it is possible that there is a link between land use within a watershed and the chemical composition of the stream. The objectives of this study are to determine if varied land use does affect the concentrations of macronutrients and trace elements present in the streams of Northwest Arkansas, and if so, to determine what extent urban and agricultural development are responsible for these changes. Water samples were collected across 19 streams in the Northwest Arkansas region between January and March of 2022. Water samples …

Decolonizing Female Archetypes: Creating An Oppositional Consciousness In Contemporary Chicana And Iraqi Women’S Fiction, Semah Salih Hussein

Graduate Theses and Dissertations

In dominant imperialist discourses, women, such as Iraqi women and Chicanas, have been marginalized in political, social and economic structures and have been manipulated to maintain imperialist exploitation and processes. They have been frozen within certain archetypal configurations. Iraqi women have been misrepresented as victims of their culture and traditions, and Chicanas have been represented in derogatory terms or excluded from mainstream hierarchies of representation. This study examines some counternarratives and oppositional subjectivities/ consciousnesses provided by Iraqi and Chicana women writers through their utilization of the legacy of a number of fictional and historical female figures. The primary texts analyzed …

Tooth Crown Morphology And Testosterone Transfer In Female Members Of Opposite-Sex Dizygotic Twin Pairs, Randall Feezell

Graduate Theses and Dissertations

The twin testosterone transfer (TTT) hypothesis posits that females gestated with male co-twins develop more masculine phenotypes due to in-utero androgen exposure. Research has shown co-gestational effects to be associated with increased deciduous and permanent tooth size in females belonging to opposite-sex dizygotic twin pairs (OSF) as compared with females belonging to same-sex monozygotic (MZF) and dizygotic (SSF) twin pairs and female siblings. This study evaluates whether the TTT hypothesis explains patterns of dental morphological variation, namely differences between OSF and other females (SSF, MZF, female siblings) in a contemporary sample that includes both deciduous and permanent data. This work …

The Work Of La Via Campesina Regarding The Intersection Of Land Occupation And Food Sovereignty, Josephine Drydale

International and Global Studies Undergraduate Honors Theses

La Via Campesina (LVC), a global movement that supports small and local farmers and their communities, is one of the world’s largest food and agricultural rights movements and advocates for agricultural rights in terms of land, ecology, human rights, and more. LVC is known for its establishment of food sovereignty, defined as the right to control one’s production and consumption of food. This new concept placed them on the map, accompanied by their aggressive editorial and advocacy work against ideals they view as neoliberal and food policies that benefit large food moguls while disenfranchising the small farmer. The concept of …

The Last Leg: A Social Sustainability Assessment Of Ovine Agriculture, Sydney Golding

International and Global Studies Undergraduate Honors Theses

Post-war agricultural transformations and the rise of Sustainability discourses have dictated the trajectory of sector industries. The implications of agriculture in lateral policy schemes have neglected the careful consideration of the social health of farmers in decision-making processes, creating a greater divide between the interests of the state and our once revered providers. This study aims to capture the complexity of social matters in agriculture within the specific context of sheep farming in the United Kingdom and the United States and how the concurrent systems have adapted considering the impacts of relevant contemporary historical contexts. The principles of Janker, Mann, …

A Tale Of Two Libraries: A History Of The Public Library Systems Of Atlanta, Ga And Baltimore, Md And How Libraries Across America Adapt To Their Communities, Gigi Powell

History Undergraduate Honors Theses

Public libraries are a staple American institution, and one that was created to adapt and react to its surrounding communities. Public libraries are unique in their ability to anticipate and fill a community’s needs, as evidenced by their constant evolution to remain relevant and provide up- to-date services to all users. To highlight this evolution, librarians from both the Fulton County Public Library System in Atlanta, GA and the Enoch Pratt Free Library system were interviewed to gauge what the library’s role is in a modern world, in a world newly ravaged by COVID-19, and how that role has evolved …

Culture In Disney Films: A Comparative Analysis Of Color, Composition And Rhythm, Megan Paul

Interior Design Undergraduate Honors Theses

As a student of design, I take inspiration from everything around me. The media I consume, the places I visit, and the people I meet.By choice or not, I and my generation are subject to the various forms of pop culture, film is one of them. Film is one of few art forms which combines several methods and elements of design to produce a cohesive result, as opposed to a singular medium. This forms the connection to design thinking and is the foundation for the study.

Another critical component to pop culture is the ability to reach the masses. Due …

Their experiences and classes, in college, allow them to develop skills and increase their chances of being successful in the workplace (Suvedi et al., 2016).

Chickering’s Seven Vectors of Student Development were used to help explain the process of student development. A quantitative survey was sent to DBCALFS faculty, staff, and administrators, and a different quantitative survey was sent …

Multi-Trophic Biodiversity Increases With Increasing Structural Complexity Of Forest Canopy, Ayanna St. Rose

Graduate Theses and Dissertations

Understanding the effects of forest canopy structural complexity on multi-trophic diversity is critical for conserving biodiversity and managing land sustainably. But multi-trophic diversity is often ignored when making decisions about land management due to lack of cost- and time-effective methods to evaluate it. Here, we explored a new method based on widely available remote sensing data to quantify canopy structural complexity and its relationships with multi-trophic biodiversity at landscape scale using 32 forested sites of the National Ecological Observatory Network. We investigated the influence of vertical and horizontal structural complexity of forest canopy on multi-trophic (primary producers, herbivores (beetles), omnivores …

Colorectal cancer is the third most common cancer in the world, and it is the fourth most common cause of cancer related death (1). There have been many significant advancements regarding the treatment of cancer which aim to shrink the size of tumors in patients. However, there is still more that needs to be understood about the many different factors that play a role in colorectal cancer development.

Angiogenesis is the process of forming new blood vessels from existing ones and it requires breaking down and remodeling of the extracellular matrix (ECM) in order to allow endothelial cells to migrate …

Pulse Rate Variability Analysis During Hemorrhage In An Experimental Porcine Model, Gabbie Bonvillain, Lauren Crimmins, Md Abul Hayat, Adria Abella Villafranca, Sam Stephens, Hanna K. Jensen, Joseph A. Sanford, Jingxian Wu, Kevin W. Sexton, Morten Jensen

Biomedical Engineering Undergraduate Honors Theses

During the acute phase of hemorrhage, heart rate and peripheral resistance increases to maintain proper oxygen delivery to vital organs. This response is mediated by the autonomic nervous system. Heart rate variability (HRV) has become a widely utilized measure to determine the autonomic nervous system control over the heart. Recently, pulse rate variability (PRV) has been suggested to serve as a surrogate for HRV. This study evaluates the ability of PRV obtained from peripheral arterial pressure waveforms as a method for detecting hemorrhage. Time domain and frequency domain metrics were evaluated for 5-minute and 15-minute arterial pressure waveform signals prior …

Effect Of Larval Experience On Learning Mate Preference In Bicyclus Anynana, Taryn Tibbs

Biological Sciences Undergraduate Honors Theses

Phenotypic traits are shaped by the interaction of an organism's genes and the environment they experience. The plasticity of phenotypic traits is particularly responsive to developmental environments which can shape adult traits, such as expressed behaviors like mate choice and the ability to learn preferences. The Lepidoptera species Bicyclus anynana has been shown to learn mate preference based on social interaction following emergence from the chrysalis, however if and how the social complexity of the larval experience affects this ability to learn is less understood. Here I test the effects of isolation during the larval period on a female’s ability …

Effects Of A Leucine Supplementation On Mitochondrial Markers In Pre-Cachectic Female Mice, Breanna Williams

Biological Sciences Undergraduate Honors Theses

Cancer cachexia is a wasting syndrome characterized by extreme weight and skeletal muscle loss that results in death in many tumor bearing individuals. Because skeletal muscle requires a high amount of energy to function, skeletal muscle fiber cells need healthy mitochondria to function. When skeletal muscle loss atrophy occurs, the mitochondrial network is degraded. Different treatments for this muscle atrophy are being studied, one of which is a leucine supplementation since leucine has been found to stimulate skeletal muscle growth in other studies. However, current data suggests that a leucine supplementation in cachexic individuals exacerbates this atrophy. PURPOSE: This study …

As a member of the orthopoxvirus family and due to its increasing emergence, it has become a pathogen in need of research. This paper works to find common trends of transmission routes and reservoir hosts in previous publications through a systematic review. Articles found on Web of Science containing the search term “Monkeypox” were sorted based on relevance to the review topics of potential reservoir hosts and transmission routes of Monkeypox virus. Through Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), 1,036 …

The Influence Of Temperature And Body Size On Food Consumption In Prairie Lizards (Sceloporus Consobrinus), Morgan Pelley

Biological Sciences Undergraduate Honors Theses

Understanding the effect of temperature on physiological and digestive processes, such as voluntary consumption rate, is critical for assessing the impact of climate change. Food consumption is required for lizard survival and reproduction and its rate is dependent on temperature. For ectotherms, as temperatures increase, the amount of food consumed to meet the energy requirements related to survival and reproduction must also increase. Information on the amount of food voluntarily consumed may aid in determining if lizards can meet energy requirements. Such information could also aid in predicting survival of lizard populations, through construction of predictive climate change models. In …

The Effects Of Time Restricted Feeding On Markers Of Type 2 Diabetes, Brooke Martin

Biological Sciences Undergraduate Honors Theses

Type 2 diabetes is one of the fastest growing chronic diseases in the country, comprising 10% of the American population. Obesity rates are at an all-time high and greatly increase risk factors for developing diabetes. Insulin resistance is the main feature of type 2 diabetes and causes management of the disease to be extremely difficult. Currently there are different possible treatments for type 2 diabetes including medication and dieting. However, diets involving fasting, though high in popularity, do not have a lot of evidence regarding their ability to prevent the development of type 2 diabetes.

Time restricted feeding (TRF) is …

The Effects Of Deletion Of The Cytoplasmic Domain Of Robo3 On Drosophila, Jessie Agcaoili

Biological Sciences Undergraduate Honors Theses

My research project examines how the deletion of the cytoplasmic domain affects the function of Robo3. If Robo3 is signaling repulsion in response to SLIT this activity should require the cytoplasmic domain. I investigated the functional importance of Robo3 by deleting the cytoplasmic domain of Robo3 using a CRISPR-based technique. This modified gene was then injected into Drosophila embryos where it replaced the normal copy of the gene. Embryos expressing the modified version of robo3 in place of normal robo3 were dissected and examined.

Exploring The Role Of Metabolites In Cancer And The Associated Nerve Crosstalk, Inah Gu, Emory A. Gregory, Casey Atwood, Sun-Ok Lee, Young Hye Song

Biomedical Engineering Faculty Publications and Presentations

Since Otto Warburg's first report on the increased uptake of glucose and lactate release by cancer cells, dysregulated metabolism has been acknowledged as a hallmark of cancer that promotes proliferation and metastasis. Over the last century, studies have shown that cancer metabolism is complex, and by-products of glucose and glutamine catabolism induce a cascade of both pro- and antitumorigenic processes. Some vitamins, which have traditionally been praised for preventing and inhibiting the proliferation of cancer cells, have also been proven to cause cancer progression in a dose-dependent manner. Importantly, recent findings have shown that the nervous system is a key …

Preparation Of Proteins And Peptides From Heat-Stabilized Defatted Rice Bran Via Solid State Fermentation And Investigating For Skin Health, Ali A. Bisly

Graduate Theses and Dissertations

Heat-stabilized defatted rice bran (HDRB) is an abundant and inexpensive agro-industrial by-product of rice milling and rice oil extraction process. Furthermore, HDRB is a potential source of proteins. However, the direct protein extraction has low yield of protein due to the impact of heat stabilization and oil extraction process which made the HDRB proteins bound and interact with other components. This research is based on using solid-state fermentation (SSF), which is a natural and cost-effective approach to facilitate protein extraction from HDRB using Bacillus subtilis (natto) Takahashi as a microorganism.

Response surface methodology (RSM) analysis was used with Box-Behnken design …

Histomonosis In Poultry: A Comprehensive Review, Lesleigh C. Beer, Victor M. Petrone-Garcia, B. Danielle Graham, Billy M. Hargis, Guillermo Tellez-Isaias, Christine N. Vuong

Poultry Science Faculty Publications and Presentations

Histomonas meleagridis, the etiological agent of histomonosis, is a poultry parasite primarily detrimental to turkeys. Characteristic lesions occur in the liver and ceca, with mortalities in turkey flocks often reaching 80–100%. Chickens and other gallinaceous birds can be susceptible but the disease was primarily considered sub-clinical until recent years. Treating and preventing H. meleagridis infection have become more difficult since 2015, when nitarsone was voluntarily removed from the market, leaving the poultry industry with no approved prophylactics, therapeutics, or vaccines to combat histomonosis. Phytogenic compounds evaluated for chemoprophylaxis of histomonosis have varied results with in vitro and in vivo …
