Variants Within Genes Edil3 And Adgrb3 Are Associated With Divergent Fecal Egg Counts In Katahdin Sheep At Weaning, Gabrielle M. Becker, Joan M. Burke, Ronald M. Lewis, James E. Miller, James L.M. Morgan, Benjamin D. Rosen, Curtis P. Van Tassell, David R. Notter, Brenda M. Murdoch

Department of Animal Science: Faculty Publications

Gastrointestinal nematodes (GIN) pose a severe threat to sheep production worldwide. Anthelmintic drug resistance coupled with growing concern regarding potential environmental effects of drug use have demonstrated the necessity of implementing other methods of GIN control. The aim of this study was to test for genetic variants associated with resistance or susceptibility to GIN in Katahdin sheep to improve the current understanding of the genetic mechanisms responsible for host response to GIN. Linear regression and casecontrol genome-wide association studies were conducted with high-density genotype data and cube-root transformed weaning fecal egg counts (tFEC) of 583 Katahdin sheep. The casecontrol GWAS …

Determining Pairwise Interactions To Predict Species Interactions In A Complex Community Of Gut Bacteria., Makenzie Maroney

Honors Program: Senior Projects (Public)

The human gastrointestinal (GI) tract houses a diverse and expansive microbial community known as the microbiota. The relationship between the host and the microbiota is considered to be mutualistic, as trillions of bacteria that reside in the hospitable GI tract can assist in essential host functions, including contributing to metabolism and immunity against disease. An important subpopulation of the GI microbiota is the mucin-associated biofilm that is comprised of a dense layer of bacteria that forms on the GI mucin layer. The mucin layer provides an alternative niche to the GI lumen; the glycans of the mucin and the subsequent …

Starvation Diets: The History And Moral Implications Of Prolonging The Lives Of Juvenile Diabetics Before The Discovery Of Insulin, Olivia Thompson

Honors Program: Senior Projects (Public)

This study explores the state of diabetology before Frederick Banting’s discovery of insulin in 1921, when juvenile diabetes was a terminal diagnosis. The widespread misunderstanding of the disease at the hands of physicians and scientists culminated in improper treatments and erroneous anatomical literature about diabetes until the age of discovery in the late 19th and early 20th centuries. More extensively, I examine the controversial work of 20th-century physician Frederick Madison Allen, who attempted to prolong the lives of juvenile diabetics by subjecting them to a rigid starvation diet by way of experimental trials lasting from 1915 to 1922. This diet …

Comparison Of Transcervical Insemination Versus Surgical Insemination Methods In Dogs At A Veterinary Clinic In Lincoln, Nebraska, Lauren Ahlers

Honors Program: Senior Projects (Public)

Artificial insemination paved the way for many advancements in reproductive technology. Two common artificial insemination methods recommended for use with frozen semen are transcervical insemination and surgical insemination. To better understand the conception rates of dogs for each method, data was collected from Hillcrest Animal Clinic. The data suggested that neither transcervical insemination nor surgical insemination was significantly better than the other. 50% of the dogs conceived when inseminated using the transcervical method, and 54.5% of the dogs conceived when inseminated using the surgical method. Based on the results, more data needs to be collected on both insemination procedures to …

Settler Colonialism And The Movement Towards Indigenous Forest Sovereignty, Madison Zucco

Honors Program: Senior Projects (Public)

This research paper examines the historical and political implications of settler colonialism on Indigenous nations in forested areas around the world. Through a thorough analysis of the Haida First Nation, Pacheedaht First Nation, and the Sámi people, it is argued that settler colonial legislation systematically and intentionally separated Indigenous people and their knowledge from forested areas. Since then, shared management protocols have been implemented to amend racist and environmentally degrading legislation on forested land, but are limited in their effect to reconcile the settler colonial legal system. The only true way to reconcile the settler colonial structure in place that …

Anti-Pornography Feminism, Kinktok, And Consent: What We Can Learn From The Sex Wars And Leather/Sadomasochistic History, Nic Cloyd

Honors Program: Senior Projects (Public)

Sex education and LGBTQA+ history have long been censored and removed from curriculums across the United States. As this information has disappeared from our education systems, important values like consent and boundary setting have become increasingly obsolete despite the modern body autonomy movement. Leather and SM culture, which began post-WWII and reached their peak in the 1970s during the sexual liberation, have become increasingly important as their ethical and moral codes have been lost over time to the HIV/AIDs epidemic and censorship from second and third wave feminsism. Two prominent movements, anti-pornography and sex-work exclusionary radical feminism, have worked to …

Understanding Queer Women’S Satisfaction With Healthcare Providers: The Role Of Positive Lgb Identity And Communication, Maddie Luebe

Honors Program: Senior Projects (Public)

Much research has explored the negative effects of having a queer identity in healthcare, such as stigmatization and discrimination, but little research examined the potential benefits of a positive LGBTQ identity in healthcare. This study investigated the relationship between having a positive LGBTQ identity and provider satisfaction through comfort communicating with a provider. This study also considered the potential effect of participants’ fear of provider heterosexism in this relationship. Survey data were collected from 506 queer-identified women in the United States. Using moderated mediation, results found that more positive feelings associated with one’s queer identity was associated with increased comfort …

The Importance Of Nutrition In Oral Health In The General Population And Among Children And Adolescents, Emma Barnes

Honors Program: Senior Projects (Public)

Having good oral health is vital for the U.S. population. Although there have been improvements, too many suffer from dental caries and tooth loss. Providing education, dental procedures, and nutritional foods can help prevent these issues. Healthy choices include having a diet with adequate protein, vitamin A, vitamin C, and the vitamin B complex to support proper tissue development in the oral cavity.

Keeping good oral health is crucial for those suffering from diabetes mellitus. Studies show that doing this can help lower the patient's A1C, therefore helping with the management of blood glucose levels and potentially slowing the progression …

Keep Calm And Carry On: Uncovering The True Blitz Spirit, Lauren Niedergeses

Honors Program: Senior Projects (Public)

First shown by Britain’s civilian population during the Blitz, this Blitz Spirit is widely understood today as a heroic display of courage, cheerfulness, unity, and the ability to “keep calm and carry on” in the face of danger and discomfort. Drawing from radio broadcasts, photographs, propaganda posters and films, and the wartime morale reports of Mass-Observation, I seek to uncover the true Blitz Spirit and how it became an integral – if somewhat mythicized – element of Britain’s modern identity. First, I explore the emergence of the Blitz Spirit during World War II, identifying gaps between reality and propagandistic myth. …

An Overlooked Epidemic: Pediatric Oral Health Concerns On The Rise In Rural Communities, Emma Verbrugge

Honors Program: Senior Projects (Public)

Pediatric oral health is a concern for many dentists and parents as they lay the foundation for long-term proper hygiene in children. Early childhood caries (ECC) is a disease of chronic tooth decay marked as the most common chronic disease of childhood in the world. Children living in rural areas are even more susceptible to this disease and thus significant attention is needed to curve these numbers. The consequences of ECC are much more than just cosmetic, but include heightened risk of gingivitis, periodontal disease, diabetes, cardiovascular disease, and much more. A foundational cause of poor dental hygiene lies with …

Application Of Linear Algebra Within The High School Curriculum: Designing Activities To Stimulate An Interest In Upper-Level Math, Shelby Castle

Honors Program: Senior Projects (Public)

This senior project outlines potential lecture activities for a guest speaker or teacher in a high school classroom to present interesting applications of linear algebra. These applications are meant to be pertinent to things students at this age level are already learning or are interested in. The activities are designed such that the ideas of upper-level math are introduced in a very guided and non-intense way. The intent of the activities is mostly applications and interesting results rather than mathematical lecturing or instruction.

The high school level courses explored in this project are chemistry, economics, and health/physical education. For these …

Agricultural Carbon Markets: How Could They Work?, Andrew Havens

Department of Environmental Studies: Undergraduate Student Theses

The resurgence of voluntary markets in which consumers can purchase carbon credits generated by agricultural carbon sequestration has brought up many questions for farmers looking to potentially enter the market. Past carbon markets, such as the Chicago Climate Exchange, ended when a recession hit, causing demand for credits to swiftly decline. How can modern voluntary markets face these challenges along with new ones and be successful? This research paper, completed as an undergraduate thesis project at the University of Nebraska-Lincoln, examines the economic and scientific factors behind soil carbon sequestration credits. An extended literature review combined with estimation of a …

This creative project was created to serve as a 10-week afterschool club curriculum for 3rd-5th graders to teach them about nutrition and healthy eating patterns. The goal of the program is to help kids establish a foundation for healthy eating that they can utilize throughout their lives, potentially reducing their risk of developing chronic diseases as an adult. Information presented during the program is a representation of the key components of the USDA MyPlate and the 2020-2025 Dietary Guidelines for Americans. The curriculum aims to teach these concepts by breaking down the different food groups, reading nutrition facts labels, and …

Influence Of Fertilizer Rate On Swollen Stem Formation (“Bulbing”) And Vitamin C Content In Different Kohlrabi Cultivars, Mark Iradukunda, Paul E. Read

Honors Program: Senior Projects (Public)

Kohlrabi (Brassica oleracea Gongylodes Group) is a vegetable crop found in the Brassicaceae, and it is rich in antioxidants such as vitamin C. Vitamin C helps in oxidative damage repair and strengthens the immune system, so exploring vitamin C sources may contribute to improving human health. The objective of this study was to determine the effect of different fertilizer rates on kohlrabi yield, in terms of the swollen stem and the vitamin C content, and if those effects are similar in different kohlrabi cultivars. In this greenhouse study, we fertilized four potted kohlrabi cultivars with a common water-soluble greenhouse fertilizer …

Department of Biochemistry: Faculty Publications

Cardiovascular diseases and metabolic complications caused by hyperlipidemia are the leading cause of death globally. In this study, the hypolipidemic potency of Sesamum indicum (SI) seeds was investigated. Of the thirty-five (35) male rats used in the study, five (5) were randomly selected for baseline measurements and thirty (30) were fed high fat diet (HFD) for four (4) weeks before random assignment into three (3) groups. The experimental group was treated with 50% SI seed, the positive control group was given a hypolipidemic drug, atorvastatin (5 mg/kg/day) while the untreated group served as the negative control. With SI administration, the …

Learning Styles, Megan Paul

Umbrella Summaries

What are learning styles?

The concept of learning styles is the idea that people differ in the way that they learn best, and instructors should determine each trainee’s optimal style and then use training methods that match the trainee’s style (Pashler, 2009). There are dozens of different learning style classifications, including such styles or dimensions as visual, auditory, kinesthetic, and tactile modality preferences (Dunn & Greggs, 2003, cited in Coffield et al., 2004); concrete vs. abstract and sequential vs. random (Gregorc, 1982a, cited in Coffield et al., 2004); holistic vs. analytic and verbalizer vs. imager (Riding & Raynor, 1998, cited …

Untangling The Placentome Gene Network Of Beef Heifers In Early Gestation, Wellison J.S. Diniz, Lawrence P. Reynolds, Alison K. Ward, Pawel P. Borowicz, Kevin K. Sedivec, Kacie L. Mccarthy, Cierrah J. Kassetas, Friederike Baumgaertner, James D. Kirsch, Sheri T. Dorsam, Tammi L. Neville, J. Chris Forcherio, Ronald R. Scott, Joel S. Caton, Carl R. Dahlen

Department of Animal Science: Faculty Publications

The cotyledon and caruncle tissues provide a functional bridge between the fetus and the dam. However, the relationship between these tissues and the transcriptomic profile that underlies the tissue functions remains elusive. Herein we investigate the expression profile of cotyledon and caruncle from nulliparous beef heifers carrying female fetuses at day 83 of pregnancy to identify changes occurring across tissues that contribute to placental function and their tissue-specific roles. We identified 2654 differentially expressed genes [padj ≤ 0.05, abs(log2FC) ≥ 1], including nutrient transporters and paternally imprinted genes. We found key regulators of tissue function and differentiation, including FOXO4, GATA2, …

Harm Reduction In The Heartland: Public Knowledge And Beliefs About Naloxone In Nebraska, Usa, Allison Schlosser, Patrick Habecker, Rick A. Bevins

Department of Psychology: Faculty Publications

Background: Opioid-related overdose deaths have been increasing in the United States (U.S.) in the last twenty years, creating a public health challenge. Take-home naloxone is an effective strategy for preventing opioid-related overdose death, but its widespread use is particularly challenging in smaller cities, towns, and rural areas where it may be stigmatized and/or poorly understood.

Methods: We analyzed data on knowledge and beliefs about drug use and naloxone among the general public in Nebraska, a largely rural state in the Great Plains region of the U.S., drawing on the 2020 Nebraska Annual Social Indicators Survey.

Results: Respondents reported negative beliefs …

Self-Compassion Mediates The Link Between Attachment Security And Intimate Relationship Quality For Couples Navigating Pregnancy, Tuyen Huynh, Eric Phillips, Rebecca L. Brock

Department of Psychology: Faculty Publications

Millions of couples navigate the transition from pregnancy to postpartum in a given year, and this period of change and adjustment in the family is associated with elevated risk for intimate relationship dysfunction. Self-compassion has the potential to promote skills that are essential for healthy adaptation (e.g., emotion regulation, greater openness and flexibility, more awareness of the needs of oneself and one’s partner). The overarching goal of the present study was to investigate the role of self-compassion in intimate relationship quality during pregnancy. A sample of 159 couples completed semi-structured interviews and questionnaires. Parents engaging in more compassionate self-responding during …

Clash And Cooperation Of Ecofeminism And Postmodern Feminism: The Intersection Of Two Theories In Dystopic Literature, Ashton Koch

Honors Program: Senior Projects (Public)

Ecofeminism and postmodern feminism are regarded as opposite theories in their attempts to solve for ecological and patriarchal oppression. This thesis argues that these two theories are not mutually exclusive, and must work together to effectively combat oppression faced by the environment and by women. It uses two works of literature, Our Life in the Forest by Marie Darrieussecq and Oryx and Crake by Margaret Atwood to argue for the combination of ecofeminist and postmodern feminist strategies. Both works are dystopic in nature, portraying the destruction of the environment and patriarchal discourse against women. Ultimately, this thesis analyzes the strategies …

Ambivalence Toward Bureaucracy: Responses From Korean School Principals, Hyun-Jun Joo, Taeyeon Kim

Department of Educational Administration: Faculty Publications

Purpose – Given the context of accountability-driven policy environments, research has shown that school leaders perceive bureaucratic rules and protocols in negative ways, but they also utilize organizational structures and routines to lead changes. To better understand both enabling and hindering mechanisms of bureaucracy in schools, this study explores how Korean school principals understand and perceive bureaucratic structures using a lens of ambivalence. The authors draw on Weber’s theory of bureaucracy, with a particular focus on the paradoxical aspect of bureaucracy that might be experienced by individuals within the system.

Design/methodology/approach – This study analyzed qualitative data collected from 26 …

Assessing Pre-Literacy Behaviors In Infants And Toddlers: Psychometric Evaluation Of The Infant Toddler Literacy Assessment (Itla-3), Barbara J. Jackson, Christine Marvin, Amy J. Encinger, Nicole Buchholz, Becky Zessin

Department of Special Education and Communication Disorders: Faculty Publications

Assessment of emerging literacy in young children is generally limited to either skill development in children over 3 years of age or the quality and context of young children’s early literacy experiences. Although there has been promotion of their early literacy experiences, assessment of emerging pre-literacy behaviors in children younger than 3 years has yet to be organized into a single tool.

Preliminary work on the Infant Toddler Literacy Assessment (ITLA) has progressed through initial steps of scale development and shown promise as a criterionbased, standardized assessment for tracking children’s pre-literacy behaviors and guiding practitioners in supporting development of those …
