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 …

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

A Geospatial Analysis Of Patterns In Neighborhood Characteristics And United States Professional Sports Stadium Relocations From 1922-2022, Kara Logan

Master's Theses

In the United States of America, 135 stadiums for new or relocating teams have been constructed between 1970 and 2020 (Bradbury et al., 2022, p. 3). Within those years, researchers, journalists, and community members have examined the impact of those new stadiums on local communities, including economic, environmental, and residential impacts. However, the current scope of literature consists of a considerable number of case studies that examine a single stadium or mega-event, such as the Olympics.

This study will determine what patterns, if any, exist between the demographic and housing characteristics between the stadiums that major league United States professional …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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) …

Characterizing The Ecological Impacts Of Utility-Scale Solar Energy (Usse) On Fallowed Farmland, Amanda Gersoff

Master's Theses

Large-scale carbon-free energy generation projects such as utility-scale solar energy (USSE) arrays help mitigate the energy sector’s contribution to climate change and are rapidly expanding throughout the U.S. However, the expansion of USSE sites is associated with immediate and longer-term ecological impacts, many of which have yet to be assessed. Quantifying the ecological impacts of USSE arrays will help to identify synergies and trade-offs between energy generation and terrestrial conservation goals. The overall goal of this research is to characterize the ecological impacts of USSE sites located on fallowed farmlands in San Luis Obispo County, California in a seasonally explicit …

Evaluating A Common Book Program's Effect On Gains In Knowledge And Position Toward Sustainability In The Nutrition Professions, Hallie Lanice Shupe

Master's Theses

A Common Reader Program, also called a common book, summer reading, or a one-book program, has been reported to enhance the college educational experience yet appears to have been underutilized by colleges and universities. In the case of health sciences, there can be great benefits in having students learn from the literature not typically found in textbooks used in the curricula. Common reader programs allow for different teaching methods to be implemented and using multiple teaching methods in a single program can be beneficial. In nutrition and dietetics (ND) programs there is a need for additional education regarding sustainability in …

Comparison Of Scanning Electron Microscopy And Confocal Laser Microscopy For Tissue Surface Roughness Characterization, Tarnvir Dhaliwal

The intent of the study is to perform a comparative study to examine efficacy of two distinct technologies for a singular purpose: tissue surface roughness characterization. The two technologies compared are a confocal reflectance microscope and a scanning electron microscope. The comparison was made by comparing two surface roughness parameters [Ra and Rq] within ImageJ.

The study examined three different animal species [porcine, bovine, and poultry] to …

Development Of An In Vitro 3-Dimensional Co-Culture Human Colorectal Cancer Model In Microfluidic Devices, Abby Jens

Master's Theses

Colorectal cancer is the second most common cause of cancer-related deaths in the United States, with the relative 5-year survival rate for distant stage cancer being only 14%. The most common treatment for colorectal cancer is with chemotherapeutic drugs; however, the discovery of these drugs is costly, time-consuming, and often requires the use of animal models that do not yield results that translate to clinical trials. Due to these shortcomings, researchers seek to develop physiologically relevant in vitro tumor models that more accurately mimic the tumor microenvironment for cheaper and faster high-throughput drug screening. The aim of this research was …

Development Of Electrical Impedance Tomography Data Acquisition System And Deep Learning-Based Reconstruction Algorithms For Spatial Damage Detection, Damond Michael Li

Master's Theses

Electrical impedance tomography (EIT) is a non-destructive, non-invasive, and non-radioactive imaging technique used for reconstructing the internal conductivity distribution of a sensing domain. Performing EIT often requires large, stationary benchtop equipment that can be expensive and impractical. Other researchers have attempted to make portable EIT systems, but they all rely on external computation for image reconstruction/data analysis. This study outlines the development of a low-cost, portable, and wireless EIT data acquisition (DAQ) system that is capable of independently performing image reconstructions on-board. With the proposed system, EIT can be performed on carbon fiber reinforced polymers to spatially locate damages. Since …

Automated Tree Mortality Detection Using Ubiquitously Available Public Data, Michael T. Huggins

Master's Theses

Understanding the dynamic interplay between fire severity, topography, and tree mortality, is crucial for predicting future forest dynamics and enhancing resilience against climate change-induced wildfire regimes. This thesis develops a multi-sensor approach for automated estimation of tree mortality, then applies it to examine trends in tree mortality over a six-year period across a fire affected study site in the Trinity River basin in Northern California. The Random Forest model uses publicly available USGS 3D Elevation Program Lidar (3DEP) and NAIP imagery as inputs and is likely to be easily adaptable to other landscapes. The model had a Receiver Operating Characteristic …

Stress Effects On The Growth Physiology Of Pacific Rockfishes (Sebastes Spp.): Negative Impacts Of Cortisol And Elevated Temperature Exposure, Hayley M. Mapes

Master's Theses

Fish experiencing stressful conditions increase production of the glucocorticoid hormone cortisol, which alters energy intake and allocation to help recover physiological homeostasis. Fish experiencing prolonged elevations of cortisol, however, often exhibit reduced somatic growth. While it has been shown previously in fish that cortisol inhibits anabolic growth processes in part via changes in endocrine growth hormone (Gh)/insulin- like growth factor-1 (Igf1) signaling, it is not fully understood which components of Gh/Igf1 pathways are modulated by cortisol. Here, we explored how cortisol influences the Gh/Igf1 system in blue rockfish (Sebastes mystinus) by administering exogenous cortisol and examining effects on …

An Exploratory Framework For Benchmarking Vehicle Miles Traveled (Vmt) Estimates Associated With University Campuses, Troy Kawahara

Master's Theses

Although vehicle miles traveled (VMT) has become the standard for assessing transportation related impacts in California, some have concerns that many VMT estimates are not properly grounded or informed by real world data, potentially resulting in flawed estimates and impact assessments. This is especially true of special generators, like college and university campuses, which have complex travel patterns distinct from that of the general public. This thesis attempts to resolve a significant disparity observed between two credible VMT estimates for Cal Poly’s campus wide VMT. As part of a campus master planning effort, a VMT estimate was produced in 2019 …

Finite Element Analysis Of The Bearing Component Of Total Ankle Replacement Implants During The Stance Phase Of Gait, Timothy S. Jain

Master's Theses

Total ankle replacement (TAR) implants are an effective option to restore the range of motion of the ankle joint for arthritic patients. An effective tool for analyzing these implants’ mechanical performance and longevity in-silico is finite element analysis (FEA). ABAQUS FEA was used to statically analyze the von Mises stress and contact pressure on the articulating surface of the bearing component in two newly installed fixed-bearing total ankle replacement implants (the Wright Medical INBONE II and the Exactech Vantage). This bearing component rotates on the talar component to induce primary ankle joint motion of plantarflexion and dorsiflexion. The stress response …

Spatial Drivers Of Soil Health In A Post-Fire Watershed, Reed Jd Williams

Master's Theses

Wildland fires are increasing in both severity and intensity leading to severe and lasting biogeochemical effects on soil. The CZU lightning complex started on August 16^th, 2020, and burned 86,509 acres causing severe social and ecological damage. To better understand the impact of fire on soil properties at the landscape scale, we created a digital soil mapping model with the inclusion of remotely sensed burn severity covariates. We combined a raster-stack of environmental covariates with rasters for fire severity and soil samples, to disentangle the relative contribution of fire to the spatial distribution of soil properties in the …
