The Effects Of Amphibole- And Sulfide-Producing Melts On Crustal Strength In Gabbros Of Lower Oceanic Crust In Oceanic Core Complexes, Mid-Atlantic And Southwest Indian Ridges, Trevor Hoffmann

Master's Theses

This study investigates gabbro-cored oceanic core complexes in the slow-spreading Mid-Atlantic Ridge (MAR) and the ultraslow spreading Southwest Indian Ridge (SWIR). Dikelets are a texture found in thin section samples from these systems that form as a result of crystal-plastic deformation. Thin section samples from the Atlantis Massif, MARK Area, and 13˚-15˚ North of the MAR and the Atlantis Bank of the SWIR were observed with petrography to find these dikelets and identify what type of dikelet is present. SEM-EDS is used to identify the mineral assemblages present in the dikelets. LA-ICP-MS is used on amphibole to determine if its …

The Application Of Particle-Correlated Raman Spectroscopic Analysis Of Soils To Mock Casework Scenarios, Sam Gong

Master's Theses

Soil is a continuous material, reaching across geological bodies, and is distinctly variable and differentiable based on aspects such as geographic location, seasonal factors, and human interference. In combination with its highly transferable nature, the complexity of soil makes it valuable material for forensic trace evidence and object-to-scene association. The development of forensic soil analysis is currently focused on mineralogy. Raman spectroscopy is a chemical technique that has previously been studied for mineralogy uses. Additionally, Raman spectroscopy has been researched for use in other fields of forensic science as well. As such, it is possible to use Raman spectroscopy for …

The Mathematics Of Financial Portfolio Optimization Incorporating Environmental, Social, And Governance Score Information, Ian Driskill

Master's Theses

We numerically investigate the effects that Environmental, Social, and Governance (ESG) scores have on portfolio optimization with Modern Portfolio Theory assumptions and how ESG scores correlate with the market returns of a rated company's stock. Additionally, we review and analyze a research paper published in the Journal of Financial Economics regarding ESG investing titled “Responsible investing: The ESG-efficient frontier” by Pedersen, Fitzgibbons, and Lukasz. Our overall goal is provide insight for socially responsible inclined investors, to help them understand what ESG scores tell us and how those scores may effect their overall investment returns."

Housing As A Determinant Of Health: Exploring The Role Of Housing And Homelessness Organizations In Increasing Access To Resources And Overcoming Barriers To Adequate And Healthy Homes, Jennifer C. Martin

Master's Theses

Across the United States, there are a multitude of barriers that stand in the way of obtaining adequate housing and additional resources that can assist with accessing housing. These barriers disproportionately impact low-income individuals and communities (Gold, 2016), and further contribute to inequity by negatively impacting the health of these individuals and communities (Swope & Hernández, 2019; Taylor, 2018). The current study explores housing organizations’ potential role in overcoming these barriers by focusing on the work of one housing organization in the Greater New Haven and Fairfield Counties of Connecticut: New Reach. 17 participants enrolled in New Reach programs were …

Does Appearance Matter? The Relationship Of Perceived Body Size And Physical Appearance On Students' Attraction To Physical Activity At Recess, Danielle Belcher

Master's Theses

Drastic declines in recess physical activity (PA) have been observed within recent years (Center for Disease Control (CDC), 2017). Due to recess’ discretionary nature, psychosocial variables associated with PA are predictors of students’ PA levels. Recess is also a time of heightened bullying occurrences (Vaillancourt et al., 2010). Appearance-based bullying is the most common type of victimization that occurs in schools, transpiring more often in children with larger body max indexes (BMI), and possibly altering students’ physical self-perceptions. Physical self-perceptions have been shown to impact PA motivation, however, it is still unknown the extent to which appearance-based bullying, body size, …

Sustainable Development: What’S The Problem Here? A Post-Structural Discourse Analysis Of The Global Reporting Initiative, Jenniffer Barnett

Master's Theses

The purpose of the study was to critically analyze how the problem of sustainable development is constructed in the Global Reporting Initiative (GRI) and identify what underlying assumptions and historical events produced the problematization as the GRI aims to guide global behavior. The study explored how governing took place by identifying what was silenced in the problem representation and the discursive effects and subject positions it produced. Carol Bacchi's (2009) "What’s the problem represented to be?" (WPR) facilitated this Foucault-influenced poststructural discourse analysis. The interrogation revealed that (a) sustainable development is characterized as a problem of corporate transparency, and (b) …

The Role Of B Cell Activation State And Sex In Aryl Hydrocarbon Receptor Mediated Induction Of Chemokine Receptor 9 And Alpha4beta7 Expression In Vitro, Logan Bauerle

Master's Theses

Defense of mucosal tissues from microbial infection and allergy is reliant on continual production of antibodies. The aryl hydrocarbon receptor (AhR) is known to regulate B cell development and is associated with suppression of systemic humoral immunity. Recent attention has been paid to the role of the AhR in altering expression of cell adhesion molecules (CAMs). B cells express CAMs and chemokine receptors to migrate around the body for localized secretion of antibodies. AhR agonists promote B cell migration to the small intestine through upregulation of chemokine receptor 9 (CCR9) and integrin α₄β₇. Both the AhR …

The Kansas Band’S Musical Depictions Of Spiritual Quests, Elizabeth Romero

Master's Theses

The progressive rock genre has been an intriguing subject of study for the scholarly community, especially within the last 30 years. An understudied part of the progressive rock scene, however, is its manifestation in the United States through the band Kansas. The band from 1970’s Topeka is acknowledged by Mitchell Morris as troublesome for critics due to the hybrid use of European art music and blues influences. It is no wonder a large study of Kansas music has not taken place due to the maligning of the band by its critics as well as the controversial views regarding pretentiousness of …

Role Of Atp-Binding Cassette (Abc) Transporters As A Protector Of Testis Stem Cell Niche From Chemotherapy Drugs In Drosophila Melanogaster, Swagata Maity

Master's Theses

In chemotherapy treatments most tumor cells are destroyed by drugs, but some tumor cells are drug resistant, and these are known as cancer stem cells (CSCs). Normal adult stem cells are also chemo resistant. Therefore, investigation of normal stem cells can be useful to provide further knowledge of CSCs. One of the primary ways that CSCs achieve drug resistance is by drug efflux through transmembrane pumps called ATP-binding cassette (ABC) transporters. Many studies on ABC transporters have been performed in vitro using cultured cell lines, but very few studies have been performed on normal stem cell populations in vivo. Drosophila …

Potential Bioprospecting Within Vemons Of Rear-Fanged Snakes, Tanner Milbank Harvey

Master's Theses

Philodryas baroni (Baron’s Green Racer) and Trimorphodon lambda (Sonoran Lyre Snake) each belong to extensively studied genera of rear-fanged venomous snakes. Investigating the bioactivities and structural composition through methods not typically included in venomic workflows, which use homologous sequences and describe venoms by their constituent peptides, provides valuable insights into both the degree and extent to which venom diversity and complexity can be overlooked by many venomic workflows. This study explores the venom compositions of P. baroni and T. lambda and compares them to published toxins observed in opisthoglyphous snakes, specifically taxon-selective three-finger toxins and metalloprotease-dominated venoms.

This study underscores …

Clonal Plants' Traits And Responses Following Fire Disturbance In Ponderosa Pine Ecosystems In The Colorado Front Range, Raymond Erskine

Master's Theses

Mountain ecosystems are currently experiencing increasing impacts of disturbances (e.g., wildfire) due to global changes in climate and land use, leading to significant changes in vegetation composition and landscape dynamics. Clonal plants, characterized by their vegetative reproduction strategies, offer a range of ecologically important traits to cope with disturbances. However, clonality is often excluded in studies of post-fire vegetation dynamics in mountain ecosystems, and our knowledge of the ability of clonal plants to respond to differing disturbance regimes is limited. Therefore, I examined the response of understory vegetation following fire disturbance in burned and unburned ponderosa pine stands of the …

Cost-Risk Analysis Of The Ercot Region Using Modern Portfolio Theory, Megan Sickinger

Master's Theses

In this work, we study the use of modern portfolio theory in a cost-risk analysis of the Electric Reliability Council of Texas (ERCOT). Based upon the risk-return concepts of modern portfolio theory, we develop an n-asset minimization problem to create a risk-cost frontier of portfolios of technologies within the ERCOT electricity region. The levelized cost of electricity for each technology in the region is a step in evaluating the expected cost of the portfolio, and the historical data of cost factors estimate the variance of cost for each technology. In addition, there are several constraints in our minimization problem to …

Chaucer’S Lists And The Parson’S Priests: Heresy, Censorship, And The Parson's Tale, Samantha Burleson

Master's Theses

Chaucer’s Parson’s Tale is a sermon on penance told by a fictional late-fourteenth-century Parson in The Canterbury Tales. What the Parson preaches is incompletely aligned with Roman Catholic orthodox beliefs, as suggested both by accusations of Lollardy elsewhere in the Canterbury Tales and heterodox features of the sermon itself. The Parson’s soteriology—the theology of how to attain salvation—invites consideration of the sermon’s potential influence from the contemporary heretical movement known as Lollardy, including the theology of John Wyclif; this theology disagreed with orthodox Catholic penitential practices.

However, despite increasing anti-Wycliffite sentiment at the turn of the fifteenth century, Chaucer’s …

Salinity Tolerance Of Flowering Rush, Butomus Umbellatus, Andrew Coomes

Master's Theses

Flowering rush is an invasive aquatic plant in North America that causes deleterious effects to native ecosystems. There are two cytotypes, a triploid and diploid, and multiple genotypes contained within the diploid cytotype currently established in the U.S. Despite its presence in river drainages connected to estuarine areas, documentation on the salinity tolerance of flowering rush is scarce. Currently, information is limited to anecdotal reports suggesting intolerance to saline conditions. A better understanding of the osmotic tolerance of this species is essential to providing insight into its’ invasive range and better inform management efforts. These studies investigated vegetative propagule germination …

How Speech-Language Pathologists Account For Self-Determination Across The Progression Of Dementia, Emilee Mcgahee

Master's Theses

Dementia diagnoses are continuing to increase, with the number of diagnoses expected to reach 231 million globally by 2050 (World Alzheimer’s Report, 2019). With this comes a greater need for Speech-Language Pathologists (SLPs) who are able to best treat those who are diagnosed. Providing person-centered and strengths-based treatment approaches for people with dementia (PWD) has been proven to increase positive engagement responses while decreasing negative engagement responses (Skrainer et al., 2007). The primary objective of this research study was to assess treatment approaches used by SLPs in dementia care setting, along with how SLPs provide person-centered dementia treatment throughout the …

This was done through comparing the Micro-CT scans of 15 samples from three different Ocean Drilling Program and International Ocean Discovery Program drill holes using the Nikon NIS Advanced Research 3-D visualization program and producing plots and statistics from MATLAB. Results indicate a wide range of textures across a range of crystal-plastic fabric intensity and Fe-Ti oxide abundance. Ultimately, there was a generally positive relationship between depth, CPF intensity, and Fe-Ti oxide …

Gestalt Language Processing In Accredited Communication Sciences And Disorders Programs, William Harris

Master's Theses

The language development and usage of autistic individuals has become a controversial topic in many of the disciplines and professions providing support to these individuals. As a result, two theories of language processing have been proposed. Analytical language processing suggests that children process and develop language from its most simple form, a phoneme, to its most complex form, a word or phrase. However, the theory of gestalt language processing proposes that some children may instead extract larger, more complex language such as whole words and phrases first and break it down to the simpler language. Gestalt language processing is often …

Molecular Characterization Of Stress Response In Western Honey Bee (Apis Mellifera), Faizan Tahir

Master's Theses

Honey bees are incredibly important for the reproduction of flowering plants and the sustainability of agricultural ecosystems. However, they face various stressors such as pesticides, pathogens, habitat loss, and climate change. Extensive research has been conducted to understand how bees respond to these stressors. Scientists have discovered that honey bees exhibit complex physiological and behavioral responses to stress at individual and colony levels. Stress can have a significant impact on their immune function, foraging behavior, and reproductive success (Decourtye et al., 2010). Understanding bee responses to stress is crucial for several reasons. Firstly, honey bees are vital for the pollination …

The Assessment Of Autonomic Function In Young Adults With An Elevated Risk Of Metabolic Syndrome, Ta'quoris Newsome

Master's Theses

Metabolic syndrome (MetS) is a complex medical condition defined by the co-occurrence of multiple cardiometabolic risk factors. Despite the well-defined profile of autonomic function in individuals with MetS, autonomic function in those with an elevated risk of developing MetS remains unclear. Our study aimed to shed light on the progression of cardiometabolic disease and its impact on autonomic function. To investigate, twenty participants, ten of whom were classified as having an elevated risk of developing MetS based on identification of risk factors using NCEP ATP III criteria, completed a two-visit study protocol. In the second visit, spontaneous cardiovagal baroreflex sensitivity …

Outside Influence And Troop Deployment, Cara Wilson

Master's Theses

This paper examines the role that the President, the public, and the media played in troop deployment during the Afghanistan War. I hypothesized that each variable would influence troop deployment. Using a linear regression, I found that there is a positive relationship between the media and troop deployment. I concluded that media coverage did not influence troop deployment, but highlighted what was happening in Afghanistan. With the public, there is a negative relationship between the public and troop deployment. While troops increased, the public decreased in their support for the war. I conclude that the public did not have a …

The Emerging Impacts Of Tourism On The Economy Of The Kingdom Of Saudi Arabia: A Comparative Study Of Oil And Tourism, Dania Abu Jabal

Master's Theses

Saudi Arabia was heavily dependent on oil, which caused an economic crisis due to the collapse of global oil prices. In 2016, the Saudi government launched Vision 2030 to diversify the Saudi economy and avoid dependence on oil revenues. One aim of Vision 2030 is to initiate numerous tourism initiatives to boost the tourism industry's economic impact, elevating its contribution from 3% of GDP to 10% by 2030.

This paper provides the necessary assessment to understand tourism's role and contribution to the Saudi economy and to determine whether the industry's growth is on the right track. Also, this paper also …

Assessing The Independent Role Of Moral Foundations In Attitudes Toward Various Justifications For Abortion, Saba Shahid

Master's Theses

Although many states have legal frameworks that restrict abortion to certain situations, largely associated with health risks to the mother, child or both, other factors, such as financial stability, emotional readiness, and partner's presence, are not covered by existing laws, though they may be critical factors contributing to abortion decisions. To assess the role of these factors, participants (N= 302) were recruited online via Prolific Academic and randomly assigned on a between participants basis to view a single vignette that manipulated abortion justification category (financial, emotional, partner) and the presence/absence of justification. They reported the extent to which …

Examining The Effects Of Food Supply On Eastern Oyster (Crassostrea Virginica) Larval Performance And Settlement Potential In Delaware Bay And Mississippi Sound, James C. Klein

Master's Theses

Oyster population maintenance and growth require sufficient larval stocks capable of timely development, growth, and successful metamorphosis, whereby larval performance and settlement potential determines the capacity for a larval cohort to effectively establish into an existing population. Exogenous factors influencing larval performance include temperature, salinity, and particularly food supply. Regarding food, a sufficiently abundant and nutritionally balanced diet composed of protein, lipids, and carbohydrates is critical for successful metamorphosis. The influence of exogenous factors on Crassostrea virginica settlement potential were examined in Delaware Bay and Mississippi Sound by incorporating in situ environmental conditions and food supply metrics into a well-established …

Supplemental High-Tech Augmentative And Alternative Communication Experiences: A Study On Graduate Student Self-Efficacy, Confidence, And Knowledge With Pre-Service Training, Emily Sikes

Master's Theses

Providing assessment and intervention with high-tech augmentative and alternative communication is within the scope of practice of American Speech-Language Pathologists (SLPS). Therefore, SLPs should be able to properly identify and implement assessment, intervention, and caregiver coaching strategies in this area of practice. Due to the lack of confidence ratings of current SLPs in providing assessment and intervention in AAC that is found in current research, this study was designed to find plausible solutions for which confidence ratings can be increased beginning at the graduate level of a Speech-Pathology Master’s program. The researchers sought to answer the following questions: “Do students …

Evaluating The Efficacy Of Detection Instructions On Additive And Contradictory Misinformation In Older And Younger Adults Using Eyewitnessed Visual Scenes, Monika Mazela

Master's Theses

Exposure to misleading details about a previous event can become incorporated into memory—a pattern termed the misinformation effect. Recently, researchers have found evidence for two types of misinformation which differ qualitatively in how they relate to details presented in the initial event. Contradictory misinformation refers to suggested details that directly contrast specific details that were presented within the witnessed event. Additive misinformation refers to suggested details that supplement a witnessed event, but do not contrast a specific detail. My thesis evaluated whether misinformation is reduced following a strong warning to detect and highlight misinformation compared to no warning and …

Effects Of Identity And Competency-Based Rejection And Acceptance On Online Versus Face To Face Reaffiliation Preferences In Adults, August Namuth

Master's Theses

Humans are social animals, resulting in notable sensitivity to experiences of acceptance and rejection. This study extends existing research by considering whether rejection or acceptance based on identity uniquely influences reaffiliation interests. Participants recalled either an inclusionary or exclusionary experience (or a control state), which would have been based on their competency or identity. Following this experience, they indicated their interest in participating in virtual and in-person social activities. I hypothesized that identity-based rejection would foster an interest in reaffiliation through online activities due to the greater availability to join likeminded groups online compared to in person. Conversely, I hypothesized …

Effects Of Ethanol On Gaba Transaminase, Mary Corrigan

Master's Theses

Ethanol is the primary active ingredient in alcoholic beverages, and functions in the body as a central nervous system (CNS) depressant. The overt effects ethanol has on the body, e.g. diminished cognitive ability, loss of motor control, slurred speech, impaired balance, etc., are well documented. While the behavioral consequences of consumption are well understood, how ethanol actually functions on a mechanistic level to elicit those effects has yet to be satisfactorily elucidated.

The structural homology between ethanol and the C3 and C4 carbons of gamma-hydroxybutyric acid (GABA), the major inhibitory neurotransmitter in the mature CNS, has led us to hypothesize …

Analysis Of Social Behavior Of The African Great Apes During Feeding And Non-Feeding Contexts, Jessica Hale

Master's Theses

The three African great apes, bonobos, chimpanzees and gorillas, despite similar habitats, differ considerably in their sociality and feeding ecology. There have been many studies that have investigated the feeding ecology and social behaviors of these species, but there is extremely limited literature available on how feeding ecology may have affected ape social evolution. Chimpanzees are frugivorous, which forces them into close proximity when foraging given the clumped nature of this resource. Bonobos and gorillas, however, are fallback food consumers, which allow them to spread out as they forage. This thesis project aims to test the hypothesis that differences in …

Faking Being Well: Evaluating The Everyday Experiences Of University Students With Chronic Pain, Hannah Ditzenberger

Master's Theses

The purpose of this project is to learn how University of Northern Colorado students with chronic pain understand their identity formation considering three intersecting factors: their transition to college, their experience of chronic pain, and their ability to engage in common practices associated with university life. Sociology is rich in literature surrounding the experiences of people with chronic illness and pain and their understanding of themselves, but the experiences of college students with chronic pain are limited. This phenomenological study relies on social psychology theories related to illness narratives, biographic disruptions, and, more broadly, self-narratives and self-presentation in its analysis. …

Clonal Growth And Trait Variation In The Colorado Front Range: The Influence Of Elevation And Ecosystem, Jordan Conley

Master's Theses

Amid global climate change, exploring adaptive strategies among alpine flora, particularly through clonal growth, becomes critical for biodiversity conservation. This study aims to explore the patterns of dominance and distributions among clonal species across environmental gradients in the Colorado Front Range, employing a trait-based comparative analysis to understand the adaptive strategies of alpine flora and their implications for conservation amid rapid climate change. We focused on two species, studying traits like lateral spread, bud count, and bulbil numbers. Advanced statistical methods such as Permutational Multivariate Analysis of Variance (PerMANOVA) and Multi-Response Permutation Procedures (MRPP) were used to evaluate community compositions …
