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) …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

DNA was extracted from known whole blood samples as well as whole blood stains placed on cotton swatches. The swatches were placed into an oven and subjected to varying temperatures (ranges from 50̊ C to 200̊ C) for different periods of time (ranging from 0 to to 12 hours) to induce degradation prior to subsequent extraction with the QIAGEN© QIAamp DNA Investigator Kit, quantification with Quantifiler Trio DNA Quantification Kit, amplification with Globalfiler PCR Amplification Kit, and capillary electrophoresis with Applied Biosystems 3500xl Genetic Analyzer, Applied …

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 …

The Immune Contribution To Postpartum Remodeling, Jessica Caroline Ming

Master's Theses

Following parturition, the uterus must undergo significant changes in size and structure through a process called postpartum remodeling. This process is known to have both pro- and anti- inflammatory components. However, how various immune cells contribute to remodeling and the pathways that promote inflammation are not well understood. We hypothesize that immune cells that infiltrate the uterus postpartum modulate inflammation to promote postpartum remodeling. Our preliminary data suggests that inflammatory cell death may contribute to the inflammation present in the early postpartum period, and thus further studies will analyze caspase-1, gasdermin D, and IL-1β and IL-18. To analyze the immune …

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 …

Semantic Segmentation Of Point Cloud Sequences Using Point Transformer V3, Marion Sisk

Master's Theses

Semantic segmentation of point clouds is a basic step for many autonomous systems including automobiles. In autonomous driving systems, LiDAR sensors are frequently used to produce point cloud sequences that allow the system to perceive the environment and navigate safely. Modern machine learning techniques for segmentation have predominately focused on single-scan segmentation, however sequence segmentation has often proven to perform better on common segmentation metrics. Using the popular Semantic KITTI dataset, we show that by providing point cloud sequences to a segmentation pipeline based on Point Transformer v3, we increase the segmentation performance between seven and fifteen percent when compared …

The overarching goal of this thesis is to understand how peripheral functionalization strategies enable distinctly different optical and electrochemical properties that may be useful for various applications. Motivated by the synthetic simplicity and tunability of DHPPs, molecules with varying design motifs were synthesized to exhibit how functionality influences optical and electrochemical properties. First, two molecules with varying …

Species Delimitation Of Slimy Salamanders, Plethodon Kisatchie And Plethodon Mississippi, Across The Lower Mississippi River, Brock Hunter Stevenson

Master's Theses

Species are fundamental units of biodiversity yet delimiting species can be challenging. Slimy Salamanders of the Plethodon glutinosus species complex are a classic example of cryptic species for which species boundaries and relationships have proved difficult to determine. Once thought to be a single species ranging across the eastern United States, protein analysis revealed high genetic divergences among geographically distinct groups of populations, leading to 16 species being recognized within the group. Two of these species, the Louisiana Slimy Salamander (Plethodon kisatchie) and the Mississippi Slimy Salamander (Plethodon mississippi), are closely related but occur on opposite sides of the Mississippi …

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 …

A Study Of Random Partitions Vs. Patient-Based Partitions In Breast Cancer Tumor Detection Using Convolutional Neural Networks, Joshua N. Ramos

Master's Theses

Breast cancer is one of the deadliest cancers for women. In the US, 1 in 8 women will be diagnosed with breast cancer within their lifetimes. Detection and diagnosis play an important role in saving lives. To this end, many classifiers with varying structures have been designed to classify breast cancer histopathological images. However, randomly partitioning data, like many previous works have done, can lead to artificially inflated accuracies and classifiers that do not generalize. Data leakage occurs when researchers assume that every image in a dataset is independent of each other, which is often not the case for medical …

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 …

Effects Of Anthropogenic Noise On The Provisioning Behavior Of Western Bluebirds And Artificial Light At Night On Nestling Development, Kerstin H. Ozkan

Master's Theses

Sensory environments are rapidly changing due to increased human activity in urban and non-urban areas alike. For instance, background sounds can interfere with parent-offspring communication and mask cues reflective of predation risk, resulting in elevated vigilance at the cost of provisioning. In chapter 1, we studied nestling provisioning behavior among Western Bluebirds (Sialia mexicana) in response to short-term (1 hr) and long-term (continuous exposure throughout nesting period) noise exposure. Provisioning rates were lower at nests exposed to short-term experimental traffic noise compared to exposure to ambient background sounds. Trial order strongly influenced provisioning behavior, with the decline in …
