Parental Child Rearing Beliefs And Children's Behavioral Problems: The Mediating Role Of Parental Involvement In Elementary School, Catalina Correa Ramirez

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

The contributions that parents make to child development have been heavily investigated but the potential links between parents’ child rearing beliefs and school involvement levels have been overlooked. In this study, a model was proposed where parental involvement was examined as a potential mediator in the relationship between parents’ child-rearing beliefs and internalizing and externalizing outcomes in children. Using data from the NICHD SECCYD study, these constructs were examined in first, third, and fifth grade (N = 1128). SEM analyses supported our hypothesis regarding the mediating effect of parental involvement and it appeared to act as a potential mediator …

Stories Of Motivation And Values Of Small-Scale Farmers In Jamaica And The United States, Raquel Taylor

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

Small-scale farmers add to global and local food systems through various means such as connecting communities to local food and support economies. Small-scale farms can address issues related to food and nutritional security. However, farming can be a challenging career to engage in, especially for those who are small-scale farmers. Matters related to succession, higher paying off-farm employment, policies, and more can make it challenging to engage in farming. Leaving the question of what would motivate someone to engage in small-scale farming. Motivation can be viewed through multiple lenses; this study chose to use self-determination theory to understand the motivations …

Spatial Hearing In Simulated Reverberant Classroom Environments, Gabriel Seth Evan Weeldreyer

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

Spatial hearing provides access to auditory spatial cues that promote speech perception in noisy listening situations. However, reverberation degrades auditory spatial cues and limits listeners’ ability to utilize these cues for segregating target speech from competing babble. Hence, spatial unmasking—an intelligibility benefit from a spatial separation between a target and masker—is reduced in reverberant environments as compared to free field. This work tests the hypothesis that interaural decorrelation, the result of increasing reverberation, will broaden the perceived auditory source width with a cascading effect of reduced auditory spatial acuity and subsequently poorer spatial unmasking. To understand the perceptual consequences of …

Carbon dioxide and Particulate matter concentrations were measured for a four-day measurement period. Then one-day, two-day, and four-day occupied time average concentrations were calculated which were then compared statistically to figure out an appropriate measurement period for these air quality variables. Kruskal Wallis test and Wilcoxon test were used to …

Impact Of Plant Defenses And Aphid-Associated Microbes In Modulating Sorghum–Sugarcane Aphid Interactions, Edith Ikuze

Department of Entomology: Dissertations, Theses, and Student Research

Sorghum (Sorghum bicolor) is a vital cereal crop globally, facing challenges from invasive pests such as the sugarcane aphid (SCA; Melanaphis sacchari). To elucidate mechanisms of sorghum resistance to SCA, we examined the role of plant defenses and the influence of aphid-associated microbes in modulating sorghum defenses. Lignin is a complex heterogenous polymer present in nearly all plant cell walls that plays a critical role in protecting plants from various stresses. In this study, we investigated the role of the caffeoyl coenzyme-A O-methyltransferase (CCoAOMT), one of the core enzymes in monolignol biosynthesis pathway that leads to lignin …

Breaking The Rule Of Silence: Childbirth And Gendered Power In Efuru And The Joys Of Motherhood, Sunday Elliott Uguru

Department of English: Dissertations, Theses, and Student Research

This study examines the thematic preoccupation of childbirth in the formative period of feminist discourse in African literature through a critical study of selected novels of Igbo women of southeastern Nigeria. The novels studied represent the earliest published African texts in English by women. The period under focus falls within the emerging stage of Nigerian literary tradition in its written form with a dominant presence of men. This study investigates the women novelists' perspective toward the failure of male authored works to represent women's childbirth experience. Through a critical reading of Flora Nwapa's Efuru and Buchi Emecheta's The Joys of …

Lessons In Persistence, Syble Heffernan

Department of English: Dissertations, Theses, and Student Research

LESSONS IN PERSISTENCE is a thesis that operates within the tradition of writing about trauma and resilience, taking up themes of mental illness, class, colonialism, loss of a parent, navigating queerness in a conservative Christian context, and reckoning with gender-based violence and expectations directed toward people socialized as women. The use of ecopoetics highlights the relationship between traumas to the earth brought about by climate change, war, and worldwide suffering, and those brought upon the human body (specifically marginalized bodies) by grief, illness, abuse, and the loss of self. The collection ultimately aims to establish explicit connections between internal and …

A Fish Out Of Water: An Examination Of Self-Identified Introverted Business Students' Perceptions Of Their Leadership Ability, Katie J. Jolicoeur

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

Current American cultural and societal ideals favor personalities that are outgoing, positive, and talkative in nature, due to the rise of the Culture of Personality (Wilmot, 2019; Kim, 2012; Cain, 2013). Beginning with the industrial revolution and expanding rapidly midcentury, parents began to view children who are quiet as less favorable than those who are more gregarious, thus children and parents began forced socialization at an earlier age (Wilmot, 2019; Cain, 2013). Very little, if any, research has been conducted to understand the impact that the cultural ideal of favoring extraversion has upon undergraduate students seeking a degree in business, …

Next-Generation Crop Monitoring Technologies: Case Studies About Edge Image Processing For Crop Monitoring And Soil Water Property Modeling Via Above-Ground Sensors, Nipuna Chamara

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

Artificial Intelligence (AI) has advanced rapidly in the past two decades. Internet of Things (IoT) technology has advanced rapidly during the last decade. Merging these two technologies has immense potential in several industries, including agriculture.

We have identified several research gaps in utilizing IoT technology in agriculture. One problem was the digital divide between rural, unconnected, or limited connected areas and urban areas for utilizing images for decision-making, which has advanced with the growth of AI. Another area for improvement was the farmers' demotivation to use in-situ soil moisture sensors for irrigation decision-making due to inherited installation difficulties. As Nebraska …

Vibratory Noise Impacts The Sensory Ecology Of A Funnel-Weaving Spider, Brandi June Pessman

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

Animals experience their world through diverse sensory systems, leveraging information from prey, predators, and potential mates to inform behavioral decisions. Environmental noise disrupts information via spectral or amplitude masking, degradation, or distortion, potentially leading to costly errors in responses. Critically, urbanization has accelerated the proliferation of novel noise sources, triggering significant shifts in communication, foraging, and predator-prey dynamics among urban wildlife. While vertebrate studies have illuminated urban animals’ flexibility to anthropogenic acoustic noise, a comprehensive understanding requires broader investigations across diverse animal taxa and sensory modalities. To address these gaps, my dissertation explored the impacts of anthropogenic substrate-borne (vibratory) noise …

Genome-Scale Metabolic Modeling Of Chitin-Degrading Microbial Systems, Aimee Kristin Kessell

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

As a major component of fungal cell walls and exoskeletons of invertebrates, chitin is widespread in soils, constituting the second most abundant biopolymer in nature. Composed of N-acetyl-D-glucosamine chains, it serves as a vital source of nutrients, including both carbon and nitrogen, for the growth of microorganisms. A solid understanding of the microbial degradation of chitin is critical for predicting their impacts on biogeochemical cycling in soil ecosystems. Organisms that degrade biopolymers (degraders) produce energetically expensive extracellular enzymes to break down complex organic carbons into simpler labile forms that are sharable with other species, including those that do not contribute …

The Relationship Between Sex Education And Women’S Sexual Liberation And Exploration: A Phenomenological Study, Jessica Ann Boyles

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

Sex education in schools is a pivotal yet contentious aspect of adolescent development, with enduring impacts on individuals' sexual exploration and liberation. However, the types of sex education offered have varied over time, often disseminating misinformation, and reinforcing traditional gender norms. Particularly for women, sex education can perpetuate harmful stereotypes, limit sexual agency, and contribute to disparities in sexual and reproductive health. This qualitative study aims to address the gap of intersecting sex education and sexual identity by examining the relationship between women's sexual liberation and exploration in adulthood and the sex education they received. Drawing from a phenomenological approach, …

The Sexual Trauma Of The Female Body: Violence Against Women In Contemporary Spanish And Latin American Cultures, Lara Armenteros Garrido

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

This dissertation focuses on the idea that women’s bodies have a sexual stigma attached to them as a consequence of different forms of heteropatriarcal violence inflicted on them. From violence in public spaces, such as street harassment or the sexual exploitation of women, to the intimacy of the relationship, like intimate partner violence or the orgasm gap, it becomes increasingly difficult for women to escape violence. Through the analysis of films, documentaries, narratives, and the testimonies of women from Spain and Latin America, I argue there is still a lack of adequate sexual and emotional knowledge to help complete agency …

Sacrificial Lambs: The Perils Of Childhood In Shakespeare, Benjamin Sidney Reed

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

“Sacrificial Lambs: The Perils of Childhood in Shakespeare” utilizes childhood studies to read five Shakespearean plays and how they portray child characters in perilous situations such as kidnapping, banishment, and murder. It argues these dangers emulate real circumstances young people faced in the early modern period, including the boy actors playing these roles. The dissertation’s key research questions include how children in these plays exhibit agency in the face of danger, how they resist adult systems of power, and how audiences in the sixteenth and seventeenth centuries may have responded to these portrayals of imperiled and rebellious youths. The Introduction …

The Role Of Family And Peer Social Support Against Bullying Involvement Among Sexual Minority Latine Young Adults, Guadalupe Gutierrez

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

Bullying is a significant risk factor for healthy youth development and functioning. Research on bullying has provided evidence that bullying involvement is linked to negative mental health outcomes for young adults; however, researchers have yet to fully explore the relationship between the different bullying statuses (victims, perpetrators, bully-victims) and internalized problems (anxiety and depression), and whether peer/friend and family support serves as a protective factor. In addition, a significant amount of research on bullying has been conducted in Europe and the United States but it remains limited in Latin American countries. The current research demonstrates that bullying is a significant …

Both had similar takeaways such as aiming at improving prevention and utilizing tactics developed during the start of the pandemic like frequent testing and vaccines.

Biological Teleology In The Modern World, Kathryn Siena

Honors Program: Senior Projects (Public)

In humans, the heart moves blood through the body. Does the heart therefore have a teleological explanation? Aristotelian teleology (described in Aristotle’s Physics) is the cause-for-the-sake-of-which, or the end towards which something moves. It is evident from current scientific knowledge that there is some sort of orientation of organisms toward an end. This orientation, following Aristotle’s definition of teleology, is conceptually distinct from efficient causation. This orientation is also metaphysically distinct from efficient causation because efficient causal explanations do not properly describe the orientation. However, two common ways of describing teleological explanations imply efficient causation as a metaphysical element. …
