Developing Activities On Uncharismatic Animals Found At Omaha's Henry Doorly Zoo And Aquarium, Justin Hultquist

Honors Program: Senior Projects (Public)

The Education Department at Omaha’s Henry Doorly Zoo and Aquarium has a number of educational activities based on charismatic species found there. I wished to develop activities the department may use for less charismatic or misunderstood species at the zoo. I began by surveying the exhibits at the zoo and taking note of what species or groups didn’t receive as much visitor engagement, or what comments were made on species that were incorrect. I then began to brainstorm and narrow down potential species that I could develop an educational activity around. As I began to develop and create activities, a …

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 …

Dancing And Poetry: A Study Of The Whirling Dervish Dance Through Rumi’S Poetry, Tasneem Huq

Honors Program: Senior Projects (Public)

This exploration investigates the influence of Rumi’s book of poetry, Mathnawi, upon the Sufi practice of the Whirling Dervish dances. It argues that Rumi’s Mathnawi underlies the choreography of the Whirling Dervish dances. Each step of the dance expresses, manifests or embodies themes found in Rumi’s poetry: separation from Unity, ascension, annihilation, and a return to Unity. The thesis introduces this argument, and then discusses historical, theological, and linguistic themes related to Rumi, Sufism, and the Whirling Dervish dances. Following this, the thesis provides a framework that begins with the Neoplatonic theory of emanation grounding Rumi’s poetic thought, followed by …

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 …

Autonomous, Long-Range, Sensor Emplacement Using Unmanned Aircraft Systems, Adam Plowcha, Justin Bradley, Jacob Hoberg, Thomas Ammon, Mark Nail, Brittany Duncan, Carrick Detweiler

School of Computing: Faculty Publications

Automated, in-ground sensor emplacement can significantly improve remote, terrestrial, data collection capabilities. Utilizing a multicopter, unmanned aircraft system (UAS) for this purpose allows sensor insertion with minimal disturbance to the target site or surrounding area. However, developing an emplacement mechanism for a small multicopter, autonomy to manage the target selection and implantation process, as well as long-range deployment are challenging to address. We have developed an autonomous, multicopter UAS that can implant subsurface sensor devices. We enhanced the UAS autopilot with autonomy for target and landing zone selection, as well as ensuring the sensor is implanted properly in the ground. …

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 …

Toward The Understanding Of The 2018 Arnold, Ne Earthquake Cluster: Relocation Of Hypocenters And Establishment Of New Gravity Base Stations, Kris Guthrie

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

In 2018, 27 unexpected earthquakes occurred in central Nebraska near Arnold. These earthquakes have no readily apparent cause and no evidence of the responsible fault system is seen at the surface. A joint analysis of vintage, regional gravity and magnetic datasets before the first earthquake revealed a lineament that could represent a pre-existing fault system. New high resolution potential fields data are needed to confidently map the subsurface features around the cluster. To design a survey and collect the data, the following tasks need to be addressed: [1] The earthquakes’ hypocenters need to be improved (relocated) to increase the efficiency …

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 …

Furthering Women In Policing: How A Police Department's Duty Firearm Selection Process May Mitigate The Gender Disparity In Marksmanship, Jenna Prochnau

Honors Program: Senior Projects (Public)

Previous research has revealed that there are several benefits to increasing the representation of women in law enforcement, including less use of force, increased community trust, and better outcomes for domestic violence and sexual assault victims. While many police departments now recognize these benefits and are aiming to recruit more women, a problem persists because women are less likely to graduate from police academies than their male counterparts. A significant difference has been observed in the area of marksmanship, particularly, with more female recruits failing to meet firearm scoring standards. Currently, very little is known about how police departments select …

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 …
