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 …

Wheat, War, And Water: The Making Of Food Insecurity In Afghanistan, Karam Alkaissy Mr.

RURALS: Review of Undergraduate Research in Agricultural and Life Sciences

This paper attempts to explain why Afghanistan's exceptional dependence on wheat has produced one of the world's most severe food crises, as the crop's dietary centrality collides with environmental stress, political upheaval, and shifting agricultural systems. The FAO projects that 17.4 million people - roughly 40 percent of the population - will experience acute food insecurity in 2026; wheat supplies up to 57 percent of caloric intake, making this dependence a profound source of vulnerability. Examining wheat through culinary, climatic, political, and agricultural lenses, the paper shows that water lies at the heart of the crisis. Climate change is reducing …

Changes In Seasonal Use Of The Central Platte River Valley, Nebraska, By Sandhill Cranes, Bethany L. Ostrom

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Recent environmental change has altered migration timing and winter distribution of many bird species, including Sandhill Cranes. Historically, the Central Platte River Valley in Nebraska functioned primarily as a spring staging area for the midcontinent population, with limited fall use and rare overwintering events. I examined records of Sandhill Crane occurrences during October to January in the Central Platte River Valley from 2015-2026 using incidental observations and aerial surveys starting in 2024. Overwintering Sandhill Cranes were documented in 7 of 11 Dec/Jan, with unprecedented increases observed since 2023, peaking with approximately 42,000 Sandhill Cranes in January of 2026, the largest …

Disney And Critical Global Citizenship: Border Politics And Linguistic Decolonization In The Lion Guard, Gordana Lazić

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

In this essay, I analyze the Disney television series The Lion Guard as a site of public pedagogy and argue that the show fosters a form of critical global citizenship among young viewers. It does this, I further maintain, in two primary ways: the progressive treatment of and careful attention to immigration and border politics, and disruption of the hegemony of the English language. Through age-appropriate plot development and dialogue, The Lion Guard actively participates in public pedagogy urging future policy and decision-makers to develop critical global consciousness.

Age Reassignment Using Luminescence Dating For The Mammoth Site, Black Hills, South Dakota, Usa, Shannon A. Mahan, Jim I. Mead, P.R. Hanson, Emma T. Krolczyk, Christopher N. Jass

School of Natural Resources: Faculty Publications

The Mammoth Site (MS) at Hot Springs, South Dakota, provides a unique opportunity to reconstruct paleoenvironmental conditions on the Northern Great Plains of the United States. Previous radiocarbon analyses of mammoth bone apatite suggested the MS sinkhole was deposited ∼42–23 cal ka BP. However, two U-series ages and one thermoluminescence (TL) age ranged between 150 and 101 ka, suggesting the bones were considerably older. We analyzed six samples from the bone bed using infrared-stimulated luminescence (IRSL) on feldspars, because the quartz luminescence was saturated; the ages ranged from approximately 232 to 160 ka, showing better agreement with previous U-series and …

Comparing Non-Invasive Survey Methods For Southern Flying Squirrels (Glaucomys Volans) At The Western Edge Of Their Range, Jay E. Winfield, Jeremy A. White

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The southern flying squirrel (Glaucomys volans) is a threatened species in Nebraska that occurs along the Missouri River in the southeastern corner of the state. Recently, a population was discovered in the city of Lincoln, but it is unknown whether this population represents a natural range expansion from the Missouri River population or whether it is isolated and results from a human-assisted movement. A survey of southern flying squirrels in Nebraska is needed, but surveys of this elusive species are challenging. This study investigated and compared two noninvasive survey techniques for rapid detection of flying squirrels: acoustic detectors …

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 …

Evolution Of Propagator Wakes On The Kolbeinsey Ridge From An Integrated Geophysical Perspective, Ethan Stowell

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

Oceanic lithosphere is formed following the extension and rifting of a continent, with new material generated at mid-ocean ridges. While ridges generally spread in the direction of extension, individual spreading centers are offset by perpendicular transform faults that break the ridges into individual segments. Ridge propagation, in which one ridge segment grows at the expense of another’s shortening, has been identified in global investigations as a poorly understood component of axial reorganization. This process leaves propagator wake structures composed of faults and pseudofaults visible as lows in Earth’s gravitational field, and transferred lithosphere with a distorted magnetic signature. This study …

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 …

Exploring The Role Of Community Leaders In Building Community Resilience Against Climate Disasters: A Case Study Of A Rural Climate Vulnerable Community, Daniel Tinyogtaa Adama

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

Community resilience is widely recognized as a participatory approach to managing climate disasters. However, limited empirical research specifically examines how community leaders carry out the work of building that resilience in rural, climate-vulnerable communities. This qualitative case study addressed that issue by exploring the role of community leaders in building resilience against climate disasters in a rural, climate-vulnerable Midwestern community with a history of such events. Guided by three research questions, the study investigated how leaders identified and leveraged local assets and social networks, the strategies they used to promote collaboration, communication, and shared decision-making, and how their roles and …

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 …
