Examining Theoretically Derived Mechanisms Underlying The Relationships Between Sexual Arousal, Alcohol Use History, And Sexual Aggression, Kailey Ann Richner

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

Various interventions have attempted to reduce the rates of sexual violence perpetrated by college men; however, meta-analyses suggest interventions need to further evaluate theoretically derived mechanisms to improve outcomes (Malamuth et al., 2018; DeGue et al., 2014; Vladutiu, et al., 2011). To address this concern, the present study utilized the Integrated Theory of Sexual Offending (ITSO; Ward et al., 2016; Ward & Beech, 2008; 2006) to explore mechanisms underlying the relationships between sexual arousal, alcohol use history (AUH), and sexual aggression. Working memory, impulsivity, and affective forecasting paradigms were selected to map onto the ITSO’s neuropsychological mechanisms. The interaction between …

The Effects Of Partisanship On Legislative Support For Environmental Policies In The United States, Rachel Summers

Department of Environmental Studies: Undergraduate Student Theses

This study investigates the relationship between political partisanship and support for environmental policies at the state level in the United States from the years 2017-2022. To do this, the study focused on two policy areas, water and land, for the average proposed, enacted, and failed bills for all 50 states in the timeframe, with the states categorized as Democratic, swing, or Republican based on the 2016 and 2020 elections. While the study did find that Democratic states were more likely to introduce environmental bills than Republican states, the study also found that there was no statistical difference in the enactment …

Paying To Reduce Disparity: Financially Incentivizing Workforce Diversity And Its Effects On Managers’ Promotion Decisions And Employees’ Effort, Bret S. Sheeley

College of Business: Dissertations, Theses, and Student Research

Disparities in employee representation persist in higher-level organizational positions despite recent attention to workforce diversity and its associated benefits. In response, companies have begun integrating diversity initiatives with varying degrees of specificity (hereafter, “initiative specificity”) into their managers’ compensation packages to increase underrepresented employees’ representation in higher-level organizational positions. This study uses an experiment to examine how offering managers financial incentives to accomplish diversity initiatives (hereafter, “diversity incentives”) and initiative specificity interact to influence managers’ promotion decisions and employees’ effort choices in a promotion setting.

The results suggest that as underrepresented employees’ pre-promotion efforts increase relative to overrepresented employees’ efforts, …

An Investigation Of Information Structures In Dna, Joel Mohrmann

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

The information-containing nature of the DNA molecule has been long known and observed. One technique for quantifying the relationships existing within the information contained in DNA sequences is an entity from information theory known as the average mutual information (AMI) profile. This investigation sought to use principally the AMI profile along with a few other metrics to explore the structure of the information contained in DNA sequences.

Treating DNA sequences as an information source, several computational methods were employed to model their information structure. Maximum likelihood and maximum a posteriori estimators were used to predict missing bases in DNA sequences. …

An Autosomal Recessive Variant In Pygm Causes Myophosphorylase Deficiency In Red Angus Composite Cattle, Mackenzie Batt, Leila G. Venzor, Keri Gardner, Rachel R. Reith, Kelsey A. Roberts, Nicolas J. Herrera, Anna M. Fuller, Gary Sullivan, J. Travis Mulliniks, Matthew L. Spangler, Stephanie J. Valberg, David J. Steffen, Jessica Lynn Petersen

Department of Animal Science: Faculty Publications

Background Between 2020 and 2022, eight calves in a Nebraska herd (composite Simmental, Red Angus, Gelbvieh) displayed exercise intolerance during forced activity. In some cases, the calves collapsed and did not recover. Available sire pedigrees contained a paternal ancestor within 2–4 generations in all affected calves. Pedigrees of the calves’ dams were unavailable, however, the cows were ranch-raised and retained from prior breeding seasons, where bulls used for breeding occasionally had a common ancestor. Therefore, it was hypothesized that a de novo autosomal recessive variant was causative of exercise intolerance in these calves.

Overexpression Of Msdreb1c Modulates Growth And Improves Forage Quality In Tetraploid Alfalfa (Medicago Sativa L.), Yangyang Zhang, Zhen Wang, Fan Zhang, Xue Wang, Yajing Li, Ruicai Long, Mingna Li, Xianyang Li, Quanzhen Wang, Qingchuan Yang, Junmei Kang

Department of Agronomy and Horticulture: Faculty Publications

DREB has been reported to be involved in plant growth and response to environmental factors. However, the function of DREB in growth and development has not been elucidated in alfalfa (Medicago sativa L.), a perennial tetraploid forage cultivated worldwide. In this study, an ortholog of MtDREB1C was characterized from alfalfa and named MsDREB1C accordingly. MsDREB1C was significantly induced by abiotic stress. The transcription factor MsDREB1C resided in the nucleus and had self-transactivation activity. The MsDREB1C overexpression (OE) alfalfa displayed growth retardation under both long-day and short-day conditions, which was supported by decreased MsGA20ox and upregulated MsGA2ox in the OE …

Post-Translational Regulation Of A Bidomain Glycerol-3-Phosphate Dehydrogenase Catalyzing Glycerol Synthesis Under Salinity Stress In Chlamydomonas Reinhardtii, Itzela Cruz-Powell, Binita Subedi, Yeongho Kim, Daniela Morales-Sánchez, Heriberto D. Cerutti

Center for Plant Science Innovation: Faculty Publications

Core chlorophytes possess glycerol-3-phosphate dehydrogenases (GPDs) with an unusual bidomain structure, consisting of a glycerol-3-phosphate phosphatase (GPP) domain fused to canonical GPD domains. These plastid-localized enzymes have been implicated in stress responses, being required for the synthesis of glycerol under high salinity and triacylglycerols under nutrient deprivation. However, their regulation under varying environmental conditions is poorly understood. C. reinhardtii transgenic strains expressing constitutively bidomain GPD2 did not accumulate glycerol or triacylglycerols in the absence of any environmental stress. Although the glycerol contents of both wild type and transgenic strains increased significantly upon exposure to high salinity, cycloheximide, an inhibitor of …

Protecting The Blind Side Of Title Vii From The Blitz Of Textualism, Sean Harrison

Nebraska Law Bulletin (Selected Issues)

Just like the outcome of Brian Flores’ lawsuit against the National Football League, the existence of private affirmative action is uncertain. A case could be brought, or it might not. Even if a case is brought, the Supreme Court may not even take it up. But that does not mean we should stand idly by. By analyzing the past and by tracing judicial trends in statutory interpretation, we can see a potential blitz coming. Instead of hoping the blitz never comes, we need to proactively adjust the protection in order to not be blindsided by a potential challenge to Weber …

Data repositories for the social sciences are facing some discipline-specific challenges. This essay provides an overview of the four key challenges. In addition, five suggestions are made to strengthen domain-specific online data repositories in the social sciences, supported by good practices. Using a user-centered approach, these suggestions aim to further open up the social sciences data landscape. The essay first addresses insights regarding the sharing of quantitative and qualitative data in light of the specific needs and issues regarding these two types of data. Thereafter, we suggest (i) ‘data labs’ for novice data re-users, (ii) advocate for the repository as …

“It Didn’T Hurt Me”: Patients’ And Providers’ Perspectives On Unsupervised Take‑Home Doses, Drug Diversion, And Overdose Risks In The Provision Of Medication For Opioid Use Disorder During Covid‑19 In San Juan, Puerto Rico, Roberto Abadie, Celia B. Fisher

School of Global Integrative Studies: Faculty Publications

Background During the COVID−19 pandemic, clinics offering medication for opioid use disorder (MOUD) needed to rapidly introduce unsupervised take−home dosing, while relapsing patients and patients unable to enter treatment faced increased risks of fentanyl−related overdose deaths and other drug−related harms. Based on a qualitative study of people who inject drugs (PWID) receiving MOUD treatment and MOUD staff in Puerto Rico, this paper documents the lived experiences of patients and providers during this period and the risk perceptions and management strategies to address substance misuse and drug diversion attributable to unsupervised take−home−dose delivery

Methods In−depth qualitative interviews were conducted with patients …

Mental Healthcare Differences Between The United States, Costa Rica, And Sweden, Michaela Diehm

Honors Program: Senior Projects (Public)

Countries such as the United States, Costa Rica, and Sweden differ in the ways that they approach treatment of mental health disorders, which is due to the structure of their healthcare as well as the culture, affordability, accessibility, and type of treatment that is available to the people of that country. A literature review did not reveal a comparison of the three countries related to the topic of mental healthcare, nor use of the three selected countries to review their structures to determine the best approach to combating mental disorders before. Costa Rica and Sweden are both countries with universal …

Soil Health Cycle, Bijesh Maharjan, Saurav Das, Vesh R. Thapa, Bharat Sharma Acharya

Department of Agronomy and Horticulture: Faculty Publications

Soil health is pivotal to agricultural sustainability. Promoting and sustaining soil health management is challenging since it involves many interdependent components and steps and is an iterative process. Herein, the soil health cycle (SHC) is proposed as a soil health management cycle encompassing human dimensions, management practices, and their effects on soil health indicators (SHIs), leading to subsequent impacts on soil functions. The SHC provides a structure for an iterative testing of changes to improve soil health. A systematic review of research publications was also conducted using the Web of Science database supplemented by Elicit AI and Scopus API searches …

Sex Differences And Sex‑Specific Regulation Of Motivated Behavior By Melanin‑Concentrating Hormone: A Short Review, Isabel R. K. Kuebler, Mauricio Suárez, Ken T. Wakabayashi

Department of Psychology: Faculty Publications

Recent preclinical research exploring how neuropeptide transmitter systems regulate motivated behavior reveal the increasing importance of sex as a critical biological variable. Neuropeptide systems and their central circuits both contribute to sex differences in a range of motivated behaviors and regulate sex-specific behaviors. In this short review, we explore the current research of how sex as a biological variable influences several distinct motivated behaviors that are modulated by the melanin-concentrating hormone (MCH) neuropeptide system. First, we review how MCH regulates feeding behavior within the context of energy homeostasis differently between male and female rodents. Then, we focus on MCH’s role …

The Bloodless Period: A Transfeminine Experience, Rin Nguyen

College of Education and Human Sciences: Dissertations, Theses, and Student Research

There is limited research exploring menstruation in transgender and gender diverse (TGD) populations, and studies have primarily examined the relationship between menstruation and gender congruence. Findings revealed menstruating TGD people experienced distress related to decreased gender congruence (Eisenberg et al., 2021), and 88% of TGD people expressed interest in menstrual suppression to manage the distress (Schwartz et al., 2022). By contrast, Lowik (2020) highlighted a transfeminine person who wished to menstruate to achieve womanhood and commented on the “bloodless period” (i.e., menstrual-like symptoms in the absence of bleeding) upon receiving gender-affirming hormone therapy. To the author’s knowledge, there is no …

Establishing Consent: The Role Of Women Representatives In Passing Informed Consent Laws, Sophia Stockham

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

What predicts the adoption of informed consent laws for pelvic exams within the United States? As of January 2023, 22 states have adopted informed consent laws for pelvic examinations on women, with eleven being under Democratic control, six being Republican control, and five with divided control between the legislature and gubernatorial level at the time of adoption. Little attention, however, has been given to women’s health mandates outside the issue of abortion and to variation among state partisan adoption regarding informed consent for pelvic exams. This paper examines the impact of partisanship, the percentage of women in the legislature, and …

Between Pages And Politics: An Interdisciplinary Exploration Of Book Bans, Hannah Morrison

Department of English: Dissertations, Theses, and Student Research

Across the United States, school boards are being inundated with requests to ban books. While these conversations are often localized, what the rise in censorship across the country suggests is that there is a fierce movement behind censoring young adult literature. What is frequently erased in these campaigns are stories of people of color and queer communities, alongside topics such as sexuality, drugs, or violence. The presiding conclusion within childhood studies on how we have reached a point where censorship is abundantly common in American schools is that public discourse views children as less than or not fully formed, thus …

Characterizing And Developing Chemistry Students’ Data Analysis And Interpretation Of Chemical Data, Stephanie A. Berg

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

All chemistry students must develop competency in analyzing and making sense of data. However, there are many difficulties that chemistry students may experience while analyzing data. Many students may not use relevant prior knowledge to aid in making sense of data, or they may not form conclusions using all the data provided. Additionally, prior knowledge seems to influence one’s data analysis, but little is known about how students use it to make sense of data. Thus, I interviewed undergraduate students as they analyzed graphical data for a task and characterized how they used their prior knowledge throughout. My findings suggest …

Teacher Roles In Correction: Understanding Disciplinary Alternative School Programs In Nebraska, Philip Thomas White Iii

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

Through semi-structured interviews with teachers and semi-structured interviews-turned-testimonios of students, I have sought to understand the purposes and consequences of Disciplinary Alternative Programs (DAP). Four different locations from across the state of Nebraska were utilized with 16 teachers and two students participating. Research questions considered the purpose of DAPs to better understand how these programs fit into broader systems of schooling. While highly cautious IRB oversight limited the number of students who could be participants in this study, their insights were substantially augmented by the sixteen educators from such environments who were also interviewed. Participant responses offered nuanced and …

Constructing Refugee Identity: A Heuristic Inquiry Into Experiences Of Ukrainian Refugees, Deana Tsabak

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

Besides the despicable atrocities and devastation, Russia’s war in Ukraine caused the emergence of a group of refugees previously unknown in the U.S. and the world. The phenomenon of “Ukrainian refugees” is new to the immigration and resettlement agencies, host communities, employers, and educators. This research explores how five Ukrainians who left their homeland after the beginning of Russia’s war construct their refugee identity in the United States. Furthermore, this study aims to discover in what ways learning English in the English Language Learning (ELL) program at a community college in Nebraska influences refugee identity construction in resettlement.

This study …

Beyond The Looking Glass: Dreams And Somnial States And Spaces In Nineteenth-Century British Literature, Anne N. Nagel

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

Poised between a waning magico-theological tradition of symbolic dream interpretation and the rising influence of scientific dream theories, which equated dreaming with disorder, the dream occupied a unique space in nineteenth-century Great Britain. Dreams were coming untethered from signification, as natural philosophers deemed their content indecipherable and chaotic. Yet vestiges of early modern beliefs could still lend supernatural power and polyphony to dreams.

This was not simply a matter of making a binary choice between two ways of thinking about dreams but instead a site of collisions and coalescences. I contend that the ways in which dreams were conceptualized in …

Identity-Driven Targeted Violence: Attending To Identity, Emotion, And Personality-Related Predictors Of Attitudinal And Behavioral Prejudice, Patrick Timothy Mcgonigal

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

Identity-driven targeted violence driven by gender identity, sexuality, race, and religion overwhelmingly impacts marginalized groups of individuals. Existing evidence suggests that acts of bias on college campuses are often unreported by students, leaving those who engage in these behaviors to continue without proper redress. A great wealth of data illustrates the deleterious impacts of identity-driven behavior on student victims, including heightened psychological distress, poorer academic performance, and lower retention. In contrast, limited research has examined relevant underpinnings of perpetrating identity-driven harassment. The current dissertation developed and disseminated a large survey to undergraduate students spanning three years of data collection. The …

What's Next: How And Why States Strengthen Treaties Through Deepening Commitments, Joseph Maestas

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

States take many post-ratification actions with most designed to weaken the application of the treaty against the state. However, nearly all treaties offer ways for states to strengthen it: deepening commitments. Deepening commitments are optional post-ratification actions that allow a state to strengthen and shape implementation of the treaty. This dissertation examines deepening commitments through analysis the Convention on the Rights of the Child (CRC), the Rome Statute of the International Criminal Court (Rome Statute), and the Convention on Certain Conventional Weapons (CCW).

In Chapter 2, through a typology and process tracing cases, I argue that states influence international law …

Measuring Jury Perception Of Explainable Machine Learning And Demonstrative Evidence, Rachel Edie Sparks Rogers

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

Subjective pattern comparison has been subject to increased scrutiny by the courts and by the general public, resulting in an increased interest in pattern comparison algorithms that provide quantitative assessments of similarity for use by forensic scientists. While these algorithms would mark an improvement over current subjective comparison methods, individuals without a statistical background may struggle with the statistical concepts and language necessary for describing algorithmic methods. If algorithms are to be used, examiners must be able to testify about their use in a way that is accessible to the jury. In a series of studies, we conduct an assessment …

Do Bisexuals Thrive In The Corridor? Liminal Identity, Communication, And Well-Being, Katie Kassler

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

In this dissertation I aim to test direct and moderating associations between bisexual liminal identity, social identity complexity, micro-aggressions and micro-affirmations, and well-being. In Chapter One, I offer my theoretical definition of and position bisexuality as a liminal identity. Next in this chapter, I (a) hypothesize a direct association between bisexual liminal identity and well-being, (b) posit competing hypotheses related to social identity complexity as a positive cognitive appraisal moderator (i.e., social cure perspective) and negative cognitive appraisal moderator (i.e., uncertainty identity perspective) of the main effect, and finally (c) posit hypotheses related to individual- and group-aimed micro-aggressions and micro-affirmations …
