Political Uncertainty And Firm-Level Stock Market Reactions In The United States, Nozomi Tanaka

Honors Program: Senior Projects (Public)

Political uncertainty has become an increasingly important feature of the global economy, with major geopolitical events often triggering rapid reactions in financial markets. This study examines how geopolitical shocks affect firm-level stock market performance in the United States. Using an event study framework, the analysis evaluates cumulative returns and stock return volatility for fourteen publicly traded firms across nine major geopolitical events between 2016 and 2022, including the Brexit referendum, the U.S.–China trade war, the COVID-19 pandemic, and the Russia–Ukraine war.

The results indicate that most firms experienced negative abnormal returns around geopolitical events, suggesting that political uncertainty is generally …

From Prairie To Practice: Environmental Controls And A Forensic Taphonomic Framework In Southeastern Nebraska, Jessica F. L. Gammage

Nebraska Academy of Sciences: Programs and Proceedings

Forensic taphonomy examines the postmortem processes that affect human remains, but much of the existing research has been developed in environments that differ significantly from those encountered in the Central Great Plains. This creates limitations when applying established models to regions like southeastern Nebraska, where decomposition is shaped by tallgrass prairie ecosystems, loess-derived soils, and strong seasonal variability. Addressing this gap is important for improving the accuracy and reliability of medicolegal interpretations.

This study evaluates how environmental conditions influence decomposition in southeastern Nebraska and proposes a regionally grounded framework for forensic taphonomic research. Drawing on existing literature, regional ecological data, …

How Philip K. Dick Used The Unreliable Narrator To Transport Unwitting Acolytes, Michael Barros, Jordi Smith

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

This essay examines the use of the unreliable narrator to transport the reader into narrative worlds, specifically in Philip K. Dick's fiction. By exploring the phenomenon of narrative transportation and the role of emotions in engagement with fiction, we argue that Dick's use of the unreliable narrator significantly engages and transports readers into his narrative worlds. Subsequently, we contend that his belief in the fundamental reality of those worlds is effectively positioning himself as a gatekeeper and mediator between the narrative world and the real world, which sets him, in his mind, as a prophet, using fiction as a tool …

Evaluating The Motivations Of Participants In Online Equine Extension Courses, Sarah Vos

Department of Animal Science: Dissertations, Theses, and Student Research

Traditional program evaluations emphasize participant demographics, knowledge gain, behavior change, and program impact. However, evaluating participant motivation can provide addition insight into why participants enroll in extension programs and help explain participant engagement and persistence throughout a program. The purpose of this study was to evaluate participant motivation in two online equine extension courses and examine potential relationships between motivation, demographics, and course delivery method, and describe participant engagement in Virtual Horse Judging Camp (VHJC). This cross-sectional study utilized convenience sampling of participants in two online equine extension courses, Horse Adult Leader Training and Educational Resource (HALTER) and VHJC. The …

Navigating Queer Identities In Rural Communities: The Role Of Social Support In Shaping Lgbq+ Adolescents’ Identity Development, Michaela Elaine Pierson

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Adolescents who identify as lesbian, gay, bisexual, or queer (LGBQ+) develop their identities within complex social contexts. In rural settings, limited access to affirming resources and greater exposure to stigma may further shape identity development. Guided by social ecological and minority stress theories, this study examined whether perceived family and friend support predict identity affirmation and internalized homonegativity among rural LGBQ+ adolescents. Participants included 53 adolescents ages 13 to 18 drawn from a larger dataset. Group differences across demographic variables were examined, and regression analyses were used to evaluate the predictive role of family and friend support. No significant group …

Investigating The Links Between Parent Math Anxiety, Parenting Behaviors, And Child Math Achievement And Math Anxiety In Middle Childhood, Kimia Akhavein

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Existing research indicates that parents’ math anxiety is a robust predictor of children’s math achievement and math anxiety. The current dissertation study moved the literature forward by examining the transmission of parents’ math anxiety to children’s math achievement and math anxiety via autonomy-supportive and controlling parenting behaviors using an observational coding scheme during a homework help task when children were in second grade. The first research aim examined if parents’ autonomy supportive and controlling behaviors mediated the link between parents’ math anxiety and children’s math achievement and math anxiety one year later. The second research aim examined whether parents’ emotion …

Beyond The Cycle: How Menstruation Influences Gender Identity And Well-Being In Binary And Non-Binary Adults, Rin Nguyen

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Approximately 1.8 billion people worldwide menstruate, including transgender and gender-diverse (TGD) people, yet their experiences remain underrepresented in research. Given that menstruation can affect gender alignment and psychological well-being, understanding its impact on TGD people is critical. Gender congruence, or alignment between one’s gender identity and expression, is a key factor influencing well-being, with research linking it to reduced depression and anxiety. Furthermore, emerging research on gender euphoria, the joy experienced when gender congruence is experienced, suggests it may serve as a protective factor for mental health and well-being. Gender euphoria has been associated with reduced psychological distress and increased …

“I Never Really Thought That Would Be Something To Talk About With My Doctor”: Developing A Theory-Led Decision Aid For College Students’ Substance Use Disclosure In Healthcare, Hayley Stahl

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

College students who use drugs face compounding barriers to disclosing substance use to healthcare providers, including uncertainty about health consequences and stigma-driven identity concerns. Existing disclosure tools address neither barrier in an integrated fashion. This explanatory sequential mixed-methods study examined how constructs from the Theory of Motivated Information Management (TMIM; Afifi & Weiner, 2004) and Stigma Management Communication (SMC; Meisenbach, 2010) theory suggest factors influencing substance use disclosure among college students and shape their lived disclosure experiences. In Study 1, simultaneous-entry multiple regression analyses revealed that communication efficacy was associated with information seeking, perceived benefits of disclosure were linked to …

Nebraska And The Midwest Agtech Ecosystem: Benchmarking Innovation Investment And Translation Gaps, Ankit Chandra, Ishani Lal, Brennan Costello

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Agricultural innovation is central to the sustainable transformation of food systems, yet the capital that finances it is unevenly distributed relative to where food is produced. This paper develops a diagnostic framework for measuring this mismatch and applies it across the U.S. Midwest from 2021 to 2025, with particular emphasis on Nebraska's structural position within this landscape. Drawing on venture capital deal-flow data, 17 stakeholder interviews, and a novel strength-weakness-opportunity-gap (SWOG) ecosystem mapping methodology, we document $736 million in tracked Midwest AgTech funding across eight states (Nebraska, Iowa, Missouri, Illinois, Indiana, Kansas, North Dakota, and South Dakota). We introduce three …

Pinochet’S Upswing: The Demise Of A Democratic Society In Chile, Jacob Behnk

Honors Program: Senior Projects (Public)

In the United States, we tend to view democracy as an inviolable tenet of political life. Our nation’s founding is even romanticized as a heroic fight for liberty against the wicked tyranny of the British monarchy. It is unthinkable that democracy could ever be destroyed, let alone have the citizens cheer on those who engineer its destruction—yet this is the very situation that Chile found itself regarding Augusto Pinochet, a brutal dictator who ruled the country with an iron fist from 1973 to 1990. Pinochet would be voted out of power in a 1988 plebiscite, but still managed to win …

Tales Of The Empathic Support Provider: How Emerging Adult Women Make Sense Of Providing Empathic Support To Female Friends, Emma R. Eslinger

Department of Communication Studies: Dissertations, Theses, and Student Research

The current study explored the stories and reflections of 33 emerging adult women who made sense of their empathic support provider (ESP) identity in the context of female friendships. From the standpoint of the retrospective storytelling heuristic, within communicated narrative sense-making theory, participants told stories about their ESP identity, including how they provide support to others and reflect on the benefits of drawbacks of serving in this role (CNSM, Koenig Kellas, 2022). Under Proposition 1 of CNSM theory, meanings, values, and beliefs (MVBs) that ESP women expressed in this role were depicted as key takeaways gathered. Findings illuminated how ESP …

Ethos: A Computational Framework For Material Culture Research, Chelsea L. Grafe

Department of Textiles, Merchandising and Fashion Design: Dissertations, Theses, and Student Research

Museum catalog records make large collections searchable, but they do not always preserve the reasoning behind the claims they contain. A record may present a quilt's identity as settled while leaving the reasoning behind that claim invisible, making it difficult for later researchers to check, question, or reuse. This project asks whether museum catalog data can be analyzed in a way that keeps each analytical claim connected to the evidence that supports it. To test this question, the project applies a material-first computational framework named Ethos. Ethos formalizes an object-centered inquiry sequence in which material dependencies establish where analysis begins …

Crustal Structure Of The Vøring Plateau And Vøring Spur From Joint Refraction And Reflection Travel-Time Tomography, Anika Nawar Mayeesha

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

Crustal architecture of the Vøring Plateau and Vøring Spur in the mid-Norwegian continental margin remains debated because the geophysical data in the area do not uniquely constrain whether the crust is continental, oceanic, or transitional. This study reanalyzes wide-angle ocean-bottom seismometer data from Profile 11-03 across the Vøring passive continental margin using joint travel-time tomography of crustal refractions and Moho reflections. A total of 6,760 first-arrival picks and 542 PmP picks from sixteen instruments were inverted for P-wave velocity and reflector depth. Three starting models were inverted independently to test sensitivity to the initial crustal configuration. The first two used …

Demographic Trends And Far-Right Party Support In Europe: The Role Of The Cordon Sanitaire, Maxwell Curry

Department of Political Science: Dissertations, Theses, and Student Research

This study examines whether cordons sanitaires, institutional exclusionary arrangements common in Western and Central Europe on the part of mainstream political actors aimed to prevent far-right political parties perceived as posing a threat to liberal democratic order from entering into governing coalitions or otherwise participating in mainstream political life, condition the relationship between immigration-related demographic change and support for far-right political parties. Contemporary scholarship has extensively examined the relationship between immigration and support for far-right political parties, but comparatively little research has examined the institutional factors that potentially condition such a relationship. In an analysis of parliamentary election data …

The Process Of Alcohol-Involved Sexual Assault Disclosure: Examining Disclosure Content And Reactions From Informal Supports, Madison Elle Edwards

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Alcohol-involved sexual violence (SV), in which unwanted sexual contact is attempted or obtained without consent during or after the victim’s alcohol use is a major public health issue among young women. Research consistently shows that alcohol-involved SV can have particularly harmful mental and physical health consequences. Moreover, survivors who were drinking are more likely to receive negative reactions (e.g., blame, minimization) when they disclose their SV experiences to informal supports (e.g., friends, family). These negative reactions are consistently linked to negative psychosocial outcomes. However, little research on negative disclosure reactions has examined the content of survivors’ disclosures. The present study …

The Relationships Between Perceived Quality Of Sexual Educational Experiences From Multiple Sources And Sexual Wellbeing Outcomes In A Sample Of U.S. College Women, Alex Diede

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Sexual education comes from many sources and is important for sexual wellbeing. Much of the research on relationships between sexual education and sexual wellbeing has examined specific sources (e.g., schools or parents) and outcomes related to sexual risk-reduction, such as contraceptive use (e.g., Lameiras-Fernández et al., 2021; Widman et al., 2016). Less is known about the relationships between sexual education and positive sexual wellbeing outcomes. This study used a sample of college women to examine the relationships between the perceived quality of sexual education before college from four sources (i.e., caregivers, school, peers, self) and sexual wellbeing outcomes, including ego-focused …

A Compass For The Forest: Curriculum Opportunities In A Post-Liaison World, Meghan Otoupalik, Erica Defrain

University of Nebraska-Lincoln Libraries: Presentations

This poster highlights a project that reimagines what library instruction, faculty partnerships, and student impact looks like following the transition away from a liaison librarian model. Looking at the academic institution’s general education program’s learning outcomes that all undergraduates must complete, we found Information Literacy (IL) was already built into this multi-disciplinary program. The library was given access to the university’s repository of participating course documents and syllabi allowing us to analyze how the learning outcomes are being met, and even more insights into how IL is being taught across campus. We began a pilot program for the first of …

Initially, he studied the reasons that members of the U.S. Congress retire. This led to a longer-term collaboration with Kevin Smith and …

Can Generative Ai Make Farming Decisions? Current Status And Future Pathways: A Case Study In Row Crop Production With Chatgpt, Nipuna Chamara, Yufeng Ge, Joe Luck, Yu Pan, Saleh Taghvaeian, Cory Walters, Christopher Proctor, Daran Rudnick, Daren Redfearn

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The agricultural decision-making process is experience-based, knowledge-dependent, time-sensitive, complex, and driven by historical data. Planting, fertilization, irrigation, and chemigation are key categories in farm decision-making, and currently there is no one-shot decision-support tool that covers all these activities. Generative Artificial Intelligence (AI) models are more advanced than traditional machine learning and deep learning models. These models have been trained on vast amounts of data from the internet, allowing them to accept unstructured data in various forms and generate human-like text, solutions to problems, and scenario predictions. Given this capability, we became interested in exploring the potential of generative AI in …

The Effect Of Partisan Group-Based Emotions On Immigration Attitudes, Samantha Michelle Wiener

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation utilized a cognitive appraisal theory of emotion perspective to study the role of partisan group-based emotion in immigration attitude formation to better understand partisan immigration attitudes and preferences in the United States. Across one correlational and two experimental studies, this research showed that partisan group-based emotions predicted immigration attitudes significantly distinctly than do individual-level emotions. The first and third papers showed that group-based emotions predicted immigration attitudes. The second highlighted the role that individual-level empathy plays in immigration preferences. Taken together, to more fully understand how Americans form attitudes towards immigrants and immigration, researchers must account for both …

Hope, Incorporated: Welborn Hope As B.A. Botkin's "Promising" Oklahoma Poet, Cullen Whisenhunt

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

In 1927, a letter by then-professor at the University of Oklahoma, Roy Temple House, was published in the Ada Evening News complimenting Ada, OK, poet Welborn Hope and suggesting Hope get in touch with folklorist and literary scholar BA Botkin, also an OU faculty member. That same year, Botkin published “Oklahoma Poets, Inc.,” in which he detailed what he believed to be the three stages of a state’s literary development: the pioneer stage, the popular rhymesters stage, and finally, the union of art and life (30-31). In 1935, Botkin presented a lecture in Tulsa in which he cited Hope among …

Interparental Relationship Quality Reduces Parental Stress And Subsequent Family Dysfunction Across Pregnancy And Early Childhood, Rachel Clara-Beth Beck

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

In this multiple paper dissertation, I found that a higher quality interparental relationship, characterized by more emotional intimacy, support, responsiveness and better conflict management skills, plays a key role in reducing stress and its subsequent impact on family dynamics. Aims and hypotheses were tested using longitudinal data collected from mixed-sex couples during the pregnancy-postpartum transition and into early childhood. In study #1, higher quality interparental support during pregnancy was associated with lower postpartum stress which, in turn, predicted fewer parent–infant bonding impairments. In study #2, a mutually responsive orientation in the couple relationship during pregnancy interacted with intrapersonal regulatory resources …

Investigating Book Challenges: Reasons For Challenges, Changes In Public Opinion, And Removals In U.S. School Districts, Makena Nail

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

The American Library Association documented an increase in book challenges in the U.S. in recent years. These are attempts to censor or limit access to books on library and book store shelves and are mostly brought by organizations and elected officials. There is much more research on which particular books are challenged and the reasons for the challenges than on general public opinion about the need for limiting access to books (PBS, 2022; American Library Association, n.d.). Previous research demonstrates that when books are challenged, the underlying goal is protecting community values by limiting access to ideas that some believe …

Dividing To Survive, Fight, Or Ally: Understanding Terrorist Group Splintering, Makayla Wendland

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

The splintering of terrorist groups is extremely common, with members breaking from the ranks of an existing organization to establish a new, independent organization. At times, the process of splintering has produced some of the deadliest terrorist groups globally, significantly affecting the trajectory and intensity of conflict. Conversely, there are times when splintering can produce groups that quickly dissipate without having an impact. This variation in lethality frames the question at the center of this dissertation: how do splinter groups behave and operate in their conflict landscape?

I develop a new theory-based typology to explain variations in the behavior and …

The Intersection Between Adolescent Pregnancy, Mental Health Concerns, Stigma, And Sex Education, Madelon Cox

Honors Program: Senior Projects (Public)

This thesis discusses research from the past two decades focused on factors contributing to an increased risk of adolescent pregnancy and the lasting impact of that pregnancy. The consequences of being a pregnant adolescent can be compounded by race, gender, socioeconomic class, and access to education. Adolescent pregnancy also carries significant physical and mental health risk for the adolescent and the child. Awareness and various interventions can help pregnant adolescents or those who may be at risk for adolescent pregnancy to support them, prevent isolation, and reduce further negative mental health conditions, such as depression and anxiety.

Substance Use And Childhood Environment In Adolescent Head Injury: Examining The Effects Of Race, Jessica A. Phelps

Department of Sociology: Dissertations, Theses, and Student Research

Adolescents participating in sports are at an increased risk of concussion, which is particularly important given the difficulties with cognitive function, emotion regulation, and impulsivity that may occur as a result of this brain injury. These symptoms can predispose adolescents to subsequent concussions, leading to further damage during a critical time in neurodevelopment which can result in mental health disorder development in adulthood. It is crucial to understand what factors may predispose youth to increased rates of concussion for these reasons. As such, this paper explored whether race/ethnicity, gender, grade in school, childhood environment, and risk-taking behaviors were associated with …

Social Bonds And Dynamic Risk In Predicting Juvenile Recidivism Among Florida Probation Youth, Shadrach Sackey

Department of Sociology: Dissertations, Theses, and Student Research

Juvenile recidivism remains a persistent challenge within the United States juvenile justice system, particularly among youth supervised in community-based probation programs. This study examines how family context, school engagement, peer associations, antisocial beliefs, and overall dynamic risk are associated with recidivism among juvenile probation youth in Florida. Drawing on social bond theory and social learning theory, the analysis uses administrative data from the Florida Department of Juvenile Justice (FDJJ) Juvenile Justice Information System, including 6,215 youth who completed community-based probation supervision between 2015 and 2018. Recidivism was measured using two outcomes within a 365-day follow-up period: rearrest and readjudication. Descriptive …
