Female Preference And Prezygotic Isolation In The Fundulus Notatus Species Complex, Emilee K. Holderness

Master's Theses

Understanding how reproductive isolation arises between closely related species is central to evolutionary research. Hybridization is widespread across taxa and shaped by interactions among environmental factors, evolutionary history, genetic compatibility, and behavior. These forces often operate nonlinearly across space and time, yet mate choice is frequently assessed under artificial conditions that may not reflect natural behavior. To address this limitation, female mate preference was investigated within the Fundulus notatus species complex, where F. notatus and F. olivaceus hybridize at varying rates across replicate contact zones. Using a free-choice design, behavioral trials were conducted with individuals from populations characterized by high …

Resilience Redefined: Exploring The Impact Of Childhood Trauma On The Value Systems Of High-Achieving Corporate Men, Lana B. Henry

Graduate Theses and Dissertations

This qualitative study employed Interpretive Phenomenological Analysis (IPA) to explore how childhood trauma influences the value systems of high-achieving corporate men. In contemporary corporate culture, where stoicism, performance, and independence are often rewarded, little attention is paid to how early adversity informs internal frameworks of meaning, leadership, and success. Semi-structured interviews were conducted with six high-achieving men, all executives and leaders in high-performing industries, who self-identified as having experienced childhood trauma. Data were analyzed using a six-step IPA process and interpreted through the lens of Schwartz’s Theory of Basic Human Values and social constructivism. Findings revealed that childhood trauma deeply …

End Times: American Mortality, Death Materiality, And Social Death In The 1990s, Jordan A. Savage

Graduate Theses and Dissertations

The United States in the 1990s was marked by pervasive representations of death in popular culture. As death imagery became increasingly visible in entertainment, there was a growing detachment from the embodied, biological realities of death, a tension intensified by the ongoing AIDS crisis. This project explores how death is politicized and how decisions about who lives and dies are shaped by power. I draw on a constellation of theoretical frameworks that collectively illuminate the operations of state-sanctioned death and social abandonment. These include Michel Foucault’s concept of biopolitics, which examines the management of life by state power; Giorgio Agamben’s …

The Bacteria Who Lived: Uncovering And Mitigating The Persistence Of Pathogens In Low-Moisture Food Processing, Kavita Shripati Patil

Graduate Theses and Dissertations

Low-moisture food (LMF) processing environments pose a persistent food safety risk due to Salmonella survival and harborage on surfaces. This work investigates persistent bacterial populations (PBPs) in LMF production environments, focusing on identifying a suitable surrogate and evaluating sanitation strategies. Three potential surrogates, Escherichia coli MP 26, Enterococcus faecium, and Pediococcus acidilactici, were compared to Salmonella PBPs formed in nonfat dry milk (NFDM) on stainless steel coupons stored at 25°C under 30% or 70% relative humidity (RH) using two different inoculation methods. E. faecium showed survival patterns most similar to Salmonella, with no significant differences in log reductions (p > 0.05), …

Through the lens of a documentary, this portion in an athlete’s journey will be spotlighted to show what these leagues do for them, how they help them improve, and how they prepare them to …

Cultural Vibrations: Student Power, International Exchange, And Black America In Mai 1968, Noah Micheal Roberts

Graduate Theses and Dissertations

Abstract This thesis examines the prominence of Black Americans in the 68’ student movement in France. May 68’ incorporated a diverse and global network of social movements and political organizations, and had a notable connection to the American student movement. Black Americans had formed a large expatriate community in France which overlapped with many of the transnational connections forged by the student movements of 68’. This community was extremely notable in the French public sphere for popular works of literature and music, but its political contributions have been minimized or understudied. By utilizing student accounts, state and organizational records, and …

Lifetime Stressor Exposure, Race And Ethnicity, And Habitual Stress Processes: An Evaluation Of Repetitive Negative Thinking And Hair Cortisol Concentration, Harrison Dickens

Graduate Theses and Dissertations

Habitual stress processes are thought to influence acute stress reactivity and stress-related disease. Habitual stress processes have been shown to adapt in response to stressor exposure experienced across the lifespan. The current study seeks to explore whether two habitual stress processes, hypothalamic-pituitary-adrenal (HPA) axis activity and repetitive negative thinking (RNT), were associated with lifetime stressor exposure (self-reported and objective neighborhood-level stressors). Additionally, the current study attempts to quantify how this process may be moderated by race and ethnicity. Participants (N = 134, Mage = 18 [SDage= 1.69], 56.7% female) consisting of White (N = 52), Black (N = 37 ), …

Host-Virus Interaction Dynamics Using Sulfolobus Spindle-Shaped Virus And Host Sulfolobales System, Yeasin Ahmed

Graduate Theses and Dissertations

The Sulfolobus Spindle-shaped virus (SSV) is among the most studied archaeal viruses, particularly in extreme environments. This virus predominantly infects multiple Crenarchaea from the Sulfolobaceae family. These hosts thrive in extreme environmental conditions, such as sulfuric hot springs, with a pH of 2 to 4 and a temperature of 76-80˚C. Sulfolobales exhibit a wide geographical distribution across volcanic hot springs.

The Role Of Cleavage And Polyadenylation Spcific Factor 6 (Cpsf6) In Hematopoiesis, Fengxi Ye

Dissertations and Theses (Open Access)

Cleavage and polyadenylation specific factor 6 (Cpsf6) translocation is frequently reported in APLL, which is Acute Promyelocytic Leukemia (APL)-like acute myeloid leukemia (AML) and other types of blood diseases associated with abnormal hematopoiesis. CPSF6 is a subunit of the Cleavage Factor I mammalian (CFIm) complex, which regulates post-transcriptional alternative polyadenylation (APA) of pre-mRNAs. Previous research indicated that Cpsf6 plays an essential role in alternative polyadenylation, development, and tumorigenesis. However, the role of Cpsf6 in hematopoiesis is unknown. Given its roles in APA, development and cancer, we hypothesize that Cpsf6 plays a critical role in hematopoiesis and that its …

An Examination Of Legal Status, Law Enforcement Perception, And Crime Victimization And Reporting Among Hispanic Immigrants, Guadalupe C. Cabrera

Electronic Theses and Dissertations

This study relied on in-depth interviews with naturalized citizens and lawful permanent resident Hispanic immigrants to explore their perceptions of law enforcement and experiences with crime victimization and reporting. Past literature has explained that the absence of legal status may deter crime reporting. We added to this body of work by investigating relationships among legal status, trust, and reporting behaviors. This study finds that direct experiences with law enforcement and acquired knowledge may be a better indicator of law enforcement trust and crime reporting compared to legal status. While most participants expressed trust in law enforcement, others felt neutral due …

Department of Pediatrics Faculty Publications

BACKGROUND: Electronic nicotine delivery systems (“e-cigarettes”) are the nicotine product most commonly used by adolescents. Research, treatment, and policy could benefit from measures of adolescent e-cigarette beliefs about outcomes of use (ie, expectancies). In the current study, we developed and tested an adolescent electronic nicotine vaping expectancy measure.

METHODS: A focus group with adolescents evaluated potential e-cigarette expectancy items. A panel of national experts assisted in revision of these items. Finally, items were administered to a sample of adolescents 14-17 years old (N = 267, Mean age 15.6, SD = 1.1, 50.9% Female, 50.2% Non-Hispanic White, 22.5% Non-Hispanic Black, 14.2% …

Adolescent Online Leisure, Media Literacy, Online Victimization, And Multifaceted Well-Being During Covid-19: The Role Of Parental Support, Yunqi Wang

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

The rapid advancement of the internet and digital technology has provided opportunities for adolescents to conduct leisure activities online on a daily basis. However, research on adolescent technology use and mental health often highlights negative effects without carefully examining the specific mechanisms, which overlooks the complexity of effects of online behaviors on adolescent well-being and the importance of developing adolescents’ media literacy skills. Moreover, despite the crucial role of family dynamics in adolescent development, research on how parental support and involvement might affect adolescent technology use and well-being is still limited. The current study retrieved data from Programme for International …

Evaluation Of Performance Characteristics And Groundwater Contamination Risks Associated With On-Farm Swine Carcass Disposal Via Composting And Shallow Burial With Carbon, Gustavo Castro Garcia

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

This dissertation evaluates the performance of three on-farm swine carcass disposal methods: whole carcass composting (WCC), ground carcass composting (GCC), and shallow burial with carbon (SBC), focusing on biosecurity factors and groundwater contamination risks. Foreign animal diseases (FADs), such as African swine fever and classical swine fever, pose severe economic and animal well-being risks if introduced to the United States. With confirmation of an FAD, swine movement will be halted, creating an urgent need for practical, biosecure, and environmentally responsible on-farm disposal strategies for swine carcasses. Nebraska, as a leading swine-producing state, exemplifies the vulnerability of high-density livestock regions to …

Hormonal Modulation Of Sexual Approach And Avoidance Among Women With A History Of Sexual Trauma, Anneliis Susan Sartin-Tarm

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

A history of sexual trauma places women at a high risk for sexual dysfunction and other health sequelae, yet the influence of ovarian hormones in this population is poorly understood. This dissertation tested the theory that the effects of ovarian hormones are mediated by cognitive approach-avoidance systems to shape sexual well-being, and that this process is moderated by sexual trauma history. This was investigated across three studies examining the menstrual cycle, hormonal contraceptive use, and menopause. Across each chapter, I present complementary evidence demonstrating that hormones interact with the interpretation of ambiguous internal and external cues with respect to sexual …

Chronic Pain After Traumatic Brain Injury: Treatment Experiences And Effects On Cognition And Functioning, Rachael L. Snyder

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

Traumatic brain injury (TBI) can contribute to changes in cognitive and emotional functioning, quality of life, and psychosocial reintegration. Chronic pain is a common consequence of TBI which can uniquely impact such outcomes. Still, the exact nature of the contribution of pain on post-TBI outcomes remains unclear, and there are few existing studies exploring the treatment journey for chronic pain and injury rehabilitation through qualitative methods, specifically individual interviews with TBI survivors. This study aimed to document these narratives and to identify precisely how the experiences of TBI survivors seeking treatments, rather than the treatments themselves, impact outcomes. It also …

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

Cardiovascular diseases are one of the leading causes of mortality worldwide in which hypertension is a risk factor. Present pharmacological interventions require long-term adherence to the therapy and are often associated with undesirable side effects. Moreover, treatments have overlooked the role of the microbiome in the development of hypertension. Egg white hydrolysate (EWH) has exhibited antihypertensive properties with potential to be used as a natural alternative for the prevention and management of hypertension. However, EWH peptide’s effect on the gut microbiome remains yet to be elucidated. Studies have described that a portion of the ingested protein can remain undigested as …

Functional Genomics Of Phosphatidylcholine Biosynthesis In Saccharomyces Cerevisiae, Amanda Marie Maliva

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

Phosphatidylcholine (PtdCho) is a prominent structural building block of cell and organelle membranes in animal, plant, and fungal cells and some bacteria. Due to its abundant nature in the plasma membrane and intracellular organelle membranes in eukaryotes, the biosynthesis of PtdCho must remain regulated to preserve the correct membrane lipid composition. Dysregulations in PtdCho metabolism can lead to mitochondrial dysfunction, cell death, and the development of diseases including cancer, atherosclerosis, and hepatic diseases. Knowledge of PtdCho has remained limited to the genes involved in its three biosynthetic pathways (Kennedy (K), methylation (M), and acyltransferase (A)), despite the growing realization of …

Experiences Of Disclosure Among Transgender And Gender Diverse Sexual Assault Survivors, Merle E. Huff Ii

Scaling Laws Of Political Regime Dynamics: Stability Of Democracies And Autocracies In The Twentieth Century, Paula Pirker-Diaz, Matthew Wilson, Soenke Beier, Karoline Wiesner

Faculty Publications

In light of the current rise of authoritarian regimes and the anti-liberal tendencies in some established democracies, understanding the dynamic and statistical properties of political regimes is of critical importance. Despite their relevance, a comprehensive quantitative assessment of these dynamics on a historical scale remains largely unexplored, and the notion that democratization is an irreversible process has gone mostly unchallenged. This study provides a rigorous and quantitative analysis of political regimes worldwide by examining changes in freedoms of expression, association and electoral quality throughout the twentieth century. Utilizing the multidimensional V-Dem dataset, which covers over 170 countries across more than …

The achievement gap between rural and non-rural schools is persistent. This study examines the achievement gap problem by analyzing two groups of rural schools to better understand their ecologies and the inner workings of rural schools. Ecological Systems Theory is the framework from which this study operates while looking at the mesosystemic relationship between the microsystems of high school football teams and classrooms in the Black Belt and otherwise rural areas of Alabama and Mississippi. A non-experimental quantitative survey design was used to answer research questions that focused on the achievement gap between Black Belt and non-Black Belt rural schools …

"I'Ll Leave The Back Porch Light On:" An Exploration Of The Legitimization Of Same-Gender Male Couple Members Through Marriage And Parenthood For Those With Adverse Coming Out Experiences, Devin S. Simpkins

Seton Hall University Dissertations and Theses (ETDs)

Reczek and Bosley-Smith (2022) identified several reasons why queer adult children reported feeling compelled to maintain relationships with their rejecting parents, and the strategies that they utilized to do so. The construct of legitimization exists within a heteronormative context, contributing to the theory that adherence to cis-heteronormative relational ideals allows same-gender couples to have a greater chance of being accepted by the dominant culture (Chevrette & Eguchi, 2020). Unintentional or deliberate aligning with idealized images of traditional (i.e., cisgender and heterosexual) couples or families is a means by which same-gender couples may seek this acceptance.

The present study sought to …

3,5-Dihydroxy-4-Isopropylstilbene (Tapinarof) Is A Partial Aryl Hydrocarbon Receptor Agonist In Fish, Conner A. Dicks

All Theses

The aryl hydrocarbon receptor (AHR) is a ligand activated transcription factor that is essential in regulating development, immune homeostasis, and drug and xenobiotic metabolism. Activation of the AHR by specific ligands results in its translocation to the nucleus where it induces a myriad of gene products, including cytochrome P450 (CYP) drug metabolizing enzymes (e.g., CYP1A1) and other components of the chemical defensome, as well as inflammatory control. Interestingly, the AHR can bind a wide variety of endogenous and xenobiotic ligands which are able to induce unique downstream effects dependent on cell type, inflammatory context, and ligand stability. The AHR is …

Changing The Channel: How Queer Representation In Mainstream Media Influences Social Perceptions In Young Adult Viewers, Lillian Joy Myers

Master's Theses

This thesis investigates the impact of queer representation in mainstream film and television on young adult viewers, with particular attention to how these media portrayals influence social perceptions and cultural understandings of queerness and LGBTQ+ identities. While queer visibility in mainstream media has increased over the past two decades, the quality and complexity of that representation remain generally inconsistent and infrequent. Drawing on sociological theories of representation and cultivation, along with GLAAD (Gay and Lesbian Alliance Against Defamation)’s Vito Russo Test as a guiding framework, this study explores both the quality and impacts of LGBTQ+ media visibility. The purpose of …
