Assessing Health Implications Of Monarch Butterfly Populations And Behaviors, Kira Goldman, Kelsey E. Fisher Dr.

Honors Scholar Theses

Pollinator populations have seen massive declines over the past decade due to anthropogenic activity and climate change posing serious threats to the health of humans and ecosystems (Ulyshen & Horn, 2023). As agents responsible for the production of about 35% of micronutrient rich food crops necessary for adequate nutrition to lead healthful lives and prevent nutrition associated diseases, pollinator decline is a public health concern (Aizen et al., 2009). Monarch butterflies (Danaus plexippus) serve as bio indicators for the health of pollinator populations because of their analogous habitat and food resources shared with many other pollinator species, including bees and …

Persuasion As A Function Of Celebrity, Argument Complexity, And Need For Cognition, Stratton Stave, Blair T. Johnson Dr., Lisset Martinez-Berman, Matthew B. Jané

Honors Scholar Theses

With advertising commanding so much money as an industry, it is critical to determine what people like or do not with ads. Our focus was on three main factors within advertising, two dimensions within how the advertisement is presented, one based on the person reading the ad. The two dimensions based on presentation were the complexity of the ad, done the first time by omitting letters from the ad and the second time by swapping letters within words, and celebrity endorsement, comparing popstar Taylor Swift’s to Alicia Steele, an AI-generated celebrity. We also measured Need for Cognition (NFC), the level …

Investigating Effects Of Co-Culturing With Vibrio Fischeri On Secondary Metabolite Production Of Hawaiian Bobtail Squid Symbionts, Mariam A. Zedan

Honors Scholar Theses

Microbes are a fruitful source of natural product drug discovery since many of their secondary metabolites show defensive activity and have unique structures. However, extracting and elucidating the structure of those compounds can be challenging in vitro due to particular environmental and nutritional requirements of some bacteria. Those requirements may include proximity to other organisms that the microbes have symbiotic relationships with. Under those conditions, the organism may activate silent biosynthetic gene clusters (BGCs) responsible for production of certain secondary metabolites not typically expressed otherwise. One method of BGC induction is co-culturing with other microbes since this mimics the natural …

Diegetic Sonification For Low Vision Gamers, Jhané Dawes

Master's Theses

There are not many games designed for all players that provide accommodations for low vision users. This means that low vision users may not get to engage with the gaming community in the same way as their sighted peers. In this thesis, I explore how diegetic sonification can be used as a tool to support these low vision gamers in the typical gaming environment. I asked low vision players to engage with a prototype game level with two diegetic sonification techniques applied, without the use of their corrective lenses. I found that participants had more enjoyment and experienced less difficulty …

Desire, Motivation, And Reasons: A Defense Of Humean Theory, Benton Anderson

Philosophy Undergraduate Honors Theses

The issue of motivation is vital to contemporary debates in metaethics. In this paper, I defend the Humean theory of motivation and one version of the Humean theory of reasons. First, I defend Michael Smith's direction of fit argument for the necessity of desire and Neil Sinhababu's inference that the Humean theory of motivation is the best explanation against objections. Then, I defend a telic desire theory of reasons by arguing against belief-based theories and noting problems with various desire-based, or Humean, theories of reasons. I conclude with optimism for the compatibility of moral reasons and the telic desire theory.

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 …

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 …

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, …

Orms And Database Design, Kalim Dumas

Honors Program: Senior Projects (Public)

This thesis explores the relationship between database design and Object-Relational Mapping (ORM) design, investigating how they have evolved together and influenced each other. It addresses a theoretical discussion, a practical implementation, and some observations regarding integrating an ORM into my Senior Design project. My Senior Design project was originally built without the intention of implementing an ORM.

There are a lot of complicated discrepancies between Relational Databases (RDBs) and Object-Oriented Programming Languages (OOPLs), called the Impedance Mismatch Problem. The fact that they are both foundational pillars in software engineering means that one cannot simply change to match the other. ORMs …

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. …

Evaluating Blood Pressure Methods In Non-Traumatic Intracerebral Hemorrhage: A Two-Site Prospective Observational Study, Desiree Cihelka

Theses and Dissertations (ETD)

Purpose. Blood pressure (BP) management is difficult and complex in the treatment of acute non-traumatic intracerebral hemorrhage (ICH). Despite mean arterial pressure (MAP) being the most reliable measure of noninvasive automatic oscillometric (NIBP) in clinical practice, clinicians instead rely on systolic and diastolic blood pressure (SBP and DBP) values to guide clinical practice. Given the widespread use of NIBPs for obtaining BP values in the acute care setting, we determine the agreement between SBP, DBP, and MAP measured by NIBP, manual cuff, and Arterial lines (A-lines) in patients with ICH. Study Aims. To understand the agreement between SBP, DBP, and …

Machine Learning Image Classifier For Identifying Composition In Landscape Paintings, David Bryant

Senior Honors Theses

The purpose of this thesis is to examine the usefulness of machine learning in the art world with a simple model. This model is an image classifier designed to identify the type of classical composition present in landscape paintings.
