Recovery Of Nuclear Dna From Skeletal Remains Decomposed In Freshwater, Zoe L. Sikon

Master's Theses

This research compared freshwater and dry decomposition environments and their impact on DNA recovery from Sus scrofa domesticus(domestic pig) femora over a 3-month period. Prior to decomposition, initial cuttings were taken from "fresh" bone samples. Cuttings were then collected at 3-week intervals from waterlogged and dry bone samples. All samples were extracted using the vendor recommended protocol for the Applied Biosystems PrepFiler BTA extraction kit and an updated version of the same protocol, that substitutes Proteinase K with additional Dithiothreitol (DTT) (Thermo Fisher Scientific, 2012.). DNA quantitation was performed using pig-specific custom primer sets, with the QuantStudio 5 Real-Time …

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 …

N-Methylation Of Amphetamine By Phenylethanolamine N- Methyltransferase: Implications For Chronic Therapeutic Use, Mackenzie Pavlik

Master's Theses

In current forensic analysis, the presence of methamphetamine in a sample is routinely presumed to reflect methamphetamine abuse. This is due to the expectation that individuals either abusing, or receiving amphetamine for therapeutic purposes (e.g. as treatment for ADHD) will not generate any significant levels of methamphetamine as a product of metabolism. We have hypothesized however, that because amphetamine can serve as a substrate for methylation by phenylethanolamine n-methyltransferase (PNMT), (which will be in equilibrium with the reverse demethylation reaction) some individuals chronically taking amphetamine for therapeutic purposes may generate low levels of methamphetamine that would show up on a …

The Role Of Attachment And Childhood Trauma For Men Parenting During The Reentry Phase: A Mixed Methods Secondary Analysis, Lily A. Hoerner

Master's Theses

Mass incarceration is a major problem in the U.S., with people of color being the ones most affected by it. Most of the people who are incarcerated are men, and a stark number of these men are parents. Reentry is a critical period for people released where they return home to their communities and families and have to reintegrate into life outside of prison. The recidivism rate in the U.S. is the highest of any other nation, making reentry an important area of focus to help repair the harms caused by mass incarceration. Many men who return home from incarceration …

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, …

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 …

Reproductive (In)Justice In Contemporary Dystopian Fiction: A Critical White Feminist Analysis Of The Handmaid’S Tale (2017–) And Future Home Of The Living God (2017), Kaelyn Ireland

Master's Theses

This thesis employs a critical white feminist lens to analyze themes of human migration in two contemporary feminist dystopian texts: the TV adaptation of Margaret Atwood’s 1985 novel The Handmaid’s Tale and Louise Erdrich’s 2017 novel Future Home of the Living God. This work draws from fields and frameworks such as reproductive justice, migration studies, and Indigenous studies to create a nuanced critique of both texts and interrogate the ways whiteness impacts the feminist dystopian heroine’s story and, potentially, audience reception. I assert that HMT and FH can best be understood as a mirror for the current state of …

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 …

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. …

Athletic Identity Association And Prospective Basic Psychological Needs Satisfaction Predict Attitudes Of Collegiate Athletes Toward Seeking Help From The Athletic Department, Allie Zerr

Master's Theses

There is an epidemic of mental health issues that has begun to be more openly talked about in college athletics. In 2022, the National Collegiate Athletic Association has found that college student-athletes are now 1.5-2 times more likely to report struggling with mental health than ever before. Previous research has shown a significant association with basic psychological needs satisfaction and overall psychological well-being. Furthermore, the purpose of this study was to investigate the possible ways that reported of autonomy, competence, and relatedness need satisfaction predicted whether athletes would seek mental health services and identify how athletic identity plays into this …

An Analysis Of Resources For Developing Music Curriculum In Charter Schools With Proposals For Research Instruments Specific To The State Of Arizona, Emily Stanton

Master's Theses

A robust music curriculum is the foundation for a successful music program. With school choice becoming more prevalent, parents who prioritize musical education for their children need information about the quality of the music curriculum in all school models, including charter schools. Currently, little data is available about music programs in charter schools. This document seeks to address that lack of information with a focus on charter schools in Arizona. There were no participants involved in this research. All proposed questions have not been used for research purposes at this time and are used as examples of options for future …

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 …

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 …

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 …

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 …

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 …

The Impact Of Target Sex Typicality On Participant's Willingness To Engage In Prosocial Behaviors, Olajuwon Olagbegi

Master's Theses

One’s decision to engage in prosocial behavior relies on various pieces of social information. The physical attractiveness of a social target could inform a perceiver’s subsequent intentions. In identifying which aspect of physical attractiveness could inform these decisions, it could be possible that prosocial decisions are heightened among those with sex-typical facial structures. This study explored the extent to which sex-typical facial structures informed perceivers’ interest in the context of social activism. Participants imagined themselves as responding to a request from a social target, deciding how behavior with high-cost and low-cost options. The male or female social target was manipulated …

Deep Learning Using Vision And Lidar For Global Robot Localization, Brett E. Gowling

Master's Theses

As the field of mobile robotics rapidly expands, precise understanding of a robot’s position and orientation becomes critical for autonomous navigation and efficient task performance. In this thesis, we present a snapshot-based global localization machine learning model for a mobile robot, the e-puck, in a simulated environment. Our model uses multimodal data to predict both position and orientation using the robot’s on-board cameras and LiDAR sensor. In an effort to minimize localization error, we explore different sensor configurations by varying the number of cameras and LiDAR layers used. Additionally, we investigate the performance benefits of different multimodal fusion strategies while …

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."

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 …

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 …

The Role Of Maternal Emotion Regulation In The Relationship Between Maternal Adverse Childhood Experiences (Aces), Negative Parenting, And Child Externalizing Behaviors, Maddison Knott

Master's Theses

Exploration of the effects of maternal Adverse Childhood Experiences (ACEs) on child externalizing behaviors were conducted in the proposed study. Subtypes of ACEs, such as household dysfunction and maltreatment, and their effects on child externalizing behaviors were also examined. Maternal ACEs have shown to have negative effects on their children through use of more negative parenting practices (NPP). However, the role of maternal difficulty in emotion regulation in the link between maternal ACEs, NPP, and child externalizing behaviors has not been previously shown in the literature. Thus, the present study aimed to examine these relations, specifically with NPP as a …

This project focuses on the importance of the relationship between Fe-Ti oxide abundance and interconnectivity, and crystal-plastic deformation in Atlantis Bank, Southwest Indian Ridge by utilizing Micro-CT scanning. 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 …

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 …

Satellite Image Analysis And Sidewalk Classification Using Deep Learning Models, Subeksha Khanal

Master's Theses

Lack of sidewalk pavement can contribute to pedestrian fatalities and injuries in the USA. Although many researchers have conducted research on sidewalk detection, there are not many publicly available datasets that we would work on for sidewalk classification. In this study, I conducted classification tasks using pretrained CNN models including VGG16 and ResNet50. I extended these models by adding custom layers at the top of pretrained layers, employing various techniques to improve the classification accuracy.

The dataset comprises 4,731 images of sidewalk based on occlusion levels, including images where the sidewalk is visible from overhead and instances where sidewalk is …

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 …

Building Software At Scale: Understanding Productivity As A Product Of Software Engineering Intrinsic Factors, Gauthier Ingende Wa Boway

Master's Theses

During our education at KSU, we have learned about various factors that affect productivity such as schedule, budget, and risks, but those are often controlled outside of what we could learn as software engineering principles, patterns, or practices. On top of that, other off-work factors such as health conditions, emotional distress, or political climate, just to name a few, could drastically affect the productivity of a software engineering team. We see a demarcation between those factors that affect productivity in software engineering but are not inherent to the discipline itself, which we call resistance factors, and the factors that are …

Kinetic And Kinematic Effect Of Flag-Carrying On Referee Agility And Sprinting Performance, William Reed

Master's Theses

Within competitive soccer, assistant referees are expected to keep up with the top speed of players on the field, despite being hindered mechanically by a flag held down at their side. This ability to keep up with speed-of-play can determine effectiveness of calls on the field, yet while being tested, referees are not required to replicate the game-like state of flag-carrying. The purpose of this study was to examine kinetic and kinematic effects of flag-carrying within sprinting and change-of-direction performance in assistant referees to better inform training programs and testing protocols. 18 male referees (mean age 32.11 ± 9.08 years) …
