Exploration Of The Mental Health Impacts Of Drought On Rural Nebraskans Via Remembered Perceptions, Grace Schleining

Honors Program: Senior Projects (Public)

Drought is a sociological phenomenon. It is a well-known occurrence across the midwestern United States; the drying out of the soil, the failing of crops, and the constant dryness and heat... this is all drought. Inspired by my earliest memory of this climate phenomenon, my research question: Can we identify negative effects of drought on rural Nebraskan mental health and/or wellbeing? In this study, rural Nebraska community members, who are involved with the agricultural sector, were interviewed. They were asked questions regarding their perceptions and stories of drought using purposive sampling and snowball sampling methods. Themes throughout indicate negative mental …

Analysis Of State Climate Action Plans: What Influences States To Adopt, Ethan Yaroch

Honors Program: Senior Projects (Public)

Federal-level policies aimed to address and mitigate the effects that will arise from climate change have become an extremely polarizing issue in the United States. Given this policy stalemate, individual states have stepped up to address the national-level shortcomings by publishing state-level Climate Action Plans (CAPs). CAPs mainly consist of emissions mitigation goals and other non-binding policy initiatives that provide a basis for future compulsory legislation. This paper examines whether party identification in the state legislature, public opinion, susceptibility to the risks associated with climate change, and proximity to neighboring states with published CAPs influence states to adopt CAPs. Employing …

Stealth Morph Intervention: A Single Case Mixed Methods Design, Kristen Elise Job

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

Students who are considered “Stealth Dyslexics” may use their gifts and talents to mask their disability until the time comes when the rigor of academics peels away the mask and students are identified in middle or high school with dyslexia or reading difficulties. The primary aim of this mixed methods study was to investigate a reading fluency intervention, Stealth Morph, on identified twice exceptional (2E) students with stealth dyslexia. The intervention uses Greek and Latin roots as a morphemic approach to help students access the building blocks of academic words. The intervention consisting of 10 units to be used daily …

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 …

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 …

Or To Be Eaten Alive, Christopher Williams

School of Art, Art History, and Design: Theses and Student Creative Work

“or to be eaten alive'' is a multimedia exhibition in which I merge my own coming of age story with a mythological ecology. In this work I reclaim my queer identity by communing with my past selves in a fantasy world created through the lens of Queer Ecology and Queer Eco-Futurism. The visuals in this exhibition obscure reality. They are abstractions of the landscapes I occupy—particularly the Tallgrass prairie and Ozark ecoregions. Through a speculative, fantasy world the exhibition introduces moments of adoration, death, fracturing, growth, joy, and failure. I form, draw, color and arrange the work embracing mistakes and …

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 …

Unlocking The Door To Access And Success: The Keys Program, Timothy Paul Barshinger

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

The Keystone Education Yields Success (KEYS) program is a welfare-to-work program in Pennsylvania meant to promote financial independence through education. Across the community colleges in the state of Pennsylvania, the KEYS program has often allowed financially disadvantaged students to succeed on par with—and often surpass—their non-KEYS classmates, defying metrics that typically suggest that low-income students will struggle to succeed. The purpose of this study was to understand how and why the KEYS program at a single community college in Pennsylvania was able to foster that level of success. The study was conducted as an instrumental case study of one KEYS …

Long-Term Soil Change In The Us Great Plains: An Evaluation Of The Haas Soil Archive, Mark A. Liebig, Francisco J. Calderon, Andrea K. Clemensen, Lisa Durso, Jessica L. Duttenhefner, Jed O. Eberly, Jonathan J. Halvorson, Virginia L. Jin, Kyle Mankin, Andrew J. Margenot, Catherine E. Stewart, Scott Van Pelt, Merle F. Vigil

Department of Agronomy and Horticulture: Faculty Publications

Diverse patterns of climate and edaphic factors challenge detection of soil property change in the US Great Plains. Because detectable soil change can take decades, insights into the trajectory of soil properties frequently require long-term site monitoring and, where available, associated soil archives to enable comparisons with initial or baseline states. Unfortunately, few multi-decadal soil change investigations have been conducted in this region. Here, we document effects of dryland cropping on a suite of soil properties by comparing matched historic (1947) and contemporary (2018) soil samples from the Haas Soil Archive at three sites in the US Great Plains: Moccasin, …

Zygnematophyceae are the algal sisters of land plants. Here we sequenced four genomes of filamentous Zygnematophyceae, including chromosome-scale assemblies for three strains of Zygnema circumcarinatum. We inferred traits in the ancestor of Zygnematophyceae and land plants that might have ushered in the conquest of land by plants: expanded genes for signaling cascades, environmental response, and multicellular growth. Zygnematophyceae and land plants share all the major enzymes for cell wall synthesis and remodifications, and gene gains shaped this toolkit. Co-expression network analyses uncover gene cohorts that unite environmental signaling with multicellular developmental programs. Our data shed light on a molecular …

Can Machine Learning Models Provide Accurate Fertilizer Recommendations?, Takashi S. T. Tanaka, Gerard B. M. Heuvelink, Taro Mieno, David S. Bullock

Department of Agricultural Economics: Faculty Publications

Accurate modeling of site-specific crop yield response is key to providing farmers with accurate site-specific economically optimal input rates (EOIRs) recommendations. Many studies have demonstrated that machine learning models can accurately predict yield. These models have also been used to analyze the effect of fertilizer application rates on yield and derive EOIRs. But models with accurate yield prediction can still provide highly inaccurate input application recommendations. This study quantified the uncertainty generated when using machine learning methods to model the effect of fertilizer application on site-specific crop yield response. The study uses real on-farm precision experimental data to evaluate the …

Implications And Recommendations For U.S. Security Alliances: South Korea's Anticipated Nuclear Proliferation, Ethan Czapla

Honors Program: Senior Projects (Public)

In 2023, South Korean President Yoon Suk-yeol suggested South Korea should consider pursuing a sovereign nuclear weapon arsenal, a striking departure from the history of South Korea’s non-proliferation posture. The pursuit of a nuclear capability or redeployment of nuclear weapons has gained traction among the South Korean public, as over 70% supported acquiring a sovereign nuclear capability in 2021. In this paper, I argue nuclear proliferation in South Korea would (1) destabilize regional security, (2) diminish U.S. security alliances, and (3) undermine the international rules-based order regarding non-proliferation and offer policy recommendations for U.S. defense practitioners in order to boost …

News Deserts And Voter Turnout: How Local News Shortages Decrease Voter Participation, Lauren Penington

Honors Program: Senior Projects (Public)

How does local news impact a county’s registered voter population, associated voting patterns, and political participation? Electoral turnout is one of the most studied topics in political science, and substantial research exists into demographic factors — including race, age, and socioeconomic status — that influence an individual’s likelihood to vote. Recent studies have begun to examine the impact of societal factors — such as the internet, social media, and news — on an individual’s ability to and likelihood of fulfilling their civic obligation. This paper explores the relationship between expanding news deserts and decreasing voter turnout, proposing that as a …

Adolescent Algorithm Addiction, Canyon Skare

Honors Program: Senior Projects (Public)

There’s no question that online Social Networking Sites have contributed to the sharp decline in mental health among adolescents. This thesis explores a number of Addictive Online Behaviors that have contributed to negative mental health outcomes, namely examining at total screentime, level of engagement, and total number of accounts one has in relation to phone addiction and social media addiction. It was found that total screentime and total number of accounts were more strongly correlated with social media addiction than phone addiction. Additionally, differences in app usage among gender was explored, finding that boys favored YouTube and Discord while Girls …

Juvenile Delinquency As A Contemporary Issue In Nigeria: Understanding The Impacts Of Parenting Styles, Single Parenting, And Marital Discord, Sunkanmi Folorunsho, Oluwakemi Abdulrazaq, Victor Ajayi

Department of Sociology: Dissertations, Theses, and Student Research

When addressing juvenile delinquencies in Nigeria, it is important to consider the roles and effects of parenting styles and family structures. Although, there are no universally accepted parenting styles, evidence and studies have pointed to some parenting styles that expose children to delinquent behaviors. We examined different parenting styles comprehensively in this article and how these styles can influence juvenile delinquencies. We also discussed the association between single-parenting and behavioral outcomes; accounting how single-parenting may increase risks of delinquencies. Furthermore, marital discord was discussed and social learning theory by Albert Bandura was adopted to buttress our positions. We concluded that …

Aphid-Ant Relationships: The Role Of Cuticular Hydrocarbons And Different Chemical Stimuli In Triggeringmutualistic Behavior, Amged El-Harairy, Ahmed El-Harairy, Alaa Mahfouz

Department of Chemical and Biomolecular Engineering: Faculty Publications

In ant-aphid interactions, various aphid species offer honeydew to the ant partner and increase their density by ant attendance, whilst others never attend ant species, in which case ants tend to treat them as prey. In this regard, ants should have the ability to distinguish myrmecophile aphid species from non-mutualistic species, so that mutualistic aphids will be accepted as partners rather than prey. Although ant-aphid interactions are now the focus of chemical ecology studies, the role of the different chemical stimuli in determining mutualistic interactions has not been completely clarified. Therefore, we have investigated the cuticular hydrocarbon profile of four …

Use of animal models in preclinical transplant research is essential to the optimization of human allografts for clinical transplantation. Animal models of organ donation and preservation help to advance and improve technical elements of solid organ recovery and facilitate research of ischemia–reperfusion injury, organ preservation strategies, and future donor-based interventions. Important considerations include cost, public opinion regarding the conduct of animal research, translational value, and relevance of the animal model for clinical practice. We present an overview of two porcine models of organ donation: donation following brain death (DBD) and donation following circulatory death (DCD). The cardiovascular anatomy and physiology …

Potential Metabolite Biomarkers Of Multiple Sclerosis From Multiple Biofluids, Fatema Bhinderwala, Heidi E. Roth, Mary Filipi, Samantha Jack, Robert Powers

Robert Powers Publications

Multiple sclerosis (MS) is a chronic and progressive neurological disorder without a cure, but early intervention can slow disease progression and improve the quality of life for MS patients. Obtaining an accurate diagnosis for MS is an arduous and error-prone task that requires a combination of a detailed medical history, a comprehensive neurological exam, clinical tests such as magnetic resonance imaging, and the exclusion of other possible diseases. A simple and definitive biofluid test for MS does not exist but is highly desirable. To address this need, we have employed NMR-based metabolomics to identify potentially unique metabolite biomarkers of MS …

Imitating The “Breeder’S Eye”: Predicting Grain Yield From Measurements Of Non-Yield Traits, Hongyu Jin, Michael C. Tross, Ruijuan Tan, Linsey Newton, Ravi V. Mural, Jinliang Yang, Addie M. Thompson, James C. Schnable

Department of Agronomy and Horticulture: Faculty Publications

Plant breeding relies on information gathered from field trials to select promising new crop varieties for release to farmers and to develop genomic prediction models that can enhance the efficiency of genetic improvement in future breeding cycles. However, generating the genetic marker data required to apply genomic prediction at the early stages of a breeding program remains costly for many public-sector breeding programs as well as for many plant breeders operating in developing countries. As the pace of climate change intensifies, the time lag of developing and deploying new crop varieties requires plant breeders to make selection decisions without knowing …

A Multi-Omics Investigation Into The Mechanism Of Action Of An Anti-Tubercular Fatty Acid Analog, Isin T. Sakallioglu, Amith S. Maroli, Aline De Lima Leite, Darrell D. Marshall, Boone W. Evans, Denise K. Zinniel, Patrick H. Dussault, Raul G. Barletta, Robert Powers

Patrick Dussault Publications

The mechanism of action (MoA) of a clickable fatty acid analogue 8-(2-Cyclobuten-1-yl)octanoic acid (DA-CB) has been investigated for the first time. Proteomics, metabolomics, and lipidomics were combined with a network analysis to investigate the MoA of DA-CB against Mycobacterium smegmatis (Msm). The metabolomics results showed that DA-CB has a general MoA related to that of ethionamide, a mycolic acid inhibitor that targets enoyl-ACP reductase (InhA), but DA-CB likely inhibits a step downstream from InhA. Our combined multi-omics approach showed that DA-CB appears to disrupt the pathway leading to the biosynthesis of mycolic acids, an essential mycobacterial fatty acid …

Leveraging The Hmbc To Facilitate Metabolite Identification, Fatema Bhinderwala, Thao Vu, Thomas G. Smith, Julian Kosacki, Darrell D. Marshall, Yuhang Xu, Martha D. Morton, Robert Powers

Department of Chemistry: Faculty Publications

The accuracy and ease of metabolite assignments from a complex mixture are expected to be facilitated by employing a multi-spectral approach. The 2D ¹H-¹³C HSQC and 2D ¹H-¹H-TOCSY are the experiments commonly used for metabolite assignments. The 2D ¹H-¹³C HSQC-TOCSY and 2D ¹H-¹³C HMBC are routinely used by natural products chemists but have seen minimal usage in metabolomics despite the unique information, the nearly complete ¹H-¹H and ¹H-¹³C and spin systems provided by these experiments that may improve the accuracy and reliability …

The Precision Nitrogen Project (PNP) worked with more than 80 corn and winter wheat producers to inexpensively design and implement randomized, replicated field strip trials on whole commercial farm fields, and to provide site-specific testing of current nitrogen (N) technologies. This article proposes a conceptual framework and detailed procedure to select the N technology to be tested; design and implement field trials; generate, process, and manage field trial data; and automatically analyze, report, and share benefits from precision N technology. The selection of the N technology was farmer-driven to ensure a good fit and to increase the likelihood of future …

New Hard Tick (Acari: Ixodidae) Reports And Detection Of Rickettsia In Ticks From Sierra Nevada De Santa Marta, Colombia, Ángel Oviedo, Miguel M. Rodríguez, Fernando S. Flores, Lyda R. Castro

Harold W. Manter Laboratory of Parasitology: Library Materials

The Sierra Nevada de Santa Marta (SNSM), located in northern Colombia, is considered a geographical island with high levels of biodiversity and endemism. However, little is known about tick species and their associated microorganisms at the SNSM. In this study we sampled host-seeking ticks in areas of the town of Minca within the SNSM. We collected 47 ticks identified as Amblyomma pacae, Amblyomma longirostre, Amblyomma ovale, Amblyomma mixtum, Haemaphysalis juxtakochi, Ixodes sp. cf. Ixodes affinis and Ixodes sp. Of these ticks, we tested for Rickettsia spp. by amplifying the gltA, SCA1, and 16S rRNA genes via PCR. Rickettsia amblyommatis …
