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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 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 …

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 …

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."

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 …

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) …

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 …

A 2-D Numerical Model For Evaluating Daylight Penetration In Short Tunnels For Enhanced Driver Safety, Joachim James

Master's Theses

It is commonly assumed that daylight will adequately penetrate short tunnels, leading to the misconception that artificial lighting is unnecessary during the daytime. Past studies revealed higher frequency of crashes in short tunnels and despite that there is lack of national guidelines warranting artificial lighting for short tunnels. Inadequately lit tunnels pose safety risks, while excessive lighting can be costly. Hence, it becomes crucial to investigate the extent of daylight penetration in short tunnels and identify disappearance zones within these tunnels. This research can help determine the necessity of artificial lighting, and which specific areas of the tunnel require lighting. …

Implementing Writing Activities In A Postsecondary Tutoring Program For Students With Intellectual Disabilities, Milya Maxfield

Master's Theses

Peer mentors who work with students with intellectual disabilities at the post-secondary level are uniquely situated in their roles both as students and as tutors to assist their students not only with their academic work but also in modeling learning strategies one-on-one. This brief study, including both quantitative and qualitative survey data, establishes a baseline for tutors’ self-confidence when it comes to their own writing and tutoring their students in writing. It further examines the impact of a professional development learning opportunity on tutors’ ability to potentially practice and model a writing strategy in their sessions with their student population. …

Role Of Toll-Like Receptor 2 In Macrophage Recognition And Response To Borrelia Burgdorferi, Yukiye A. Koide

Master's Theses

Lyme disease is the most common vector-borne disease in the US and will experience an uptick as the insect host, the ixodid tick, gains habitat with climate change. The causative agent of Lyme disease, Borrelia burgdorferi, is recognized by Toll-like receptor 2 (TLR2), which initiates the innate immune response. Here, I used ELISA and SEAP detection assays to determine that knocking out TLR2 in THP-1 macrophages reduces the amount of NFkB activation, as well as IL-10 and IL-1β secretion. Then, I used fluorescence microscopy and Incucyte assays to quantify the amount of phagocytosis performed by wild-type and knock-out THP-1 cells. …

Game Changer: Mobile Apps Leveling Up Field Experiments, Lucie Schulz

Master's Theses

This study investigates the feasibility of digital financial education for microcredit borrowers with limited digital literacy in Eastern Uganda using a mobile game simulating real-world livestock investments. Analyzing 117,870 decisions made by 133 participants across five game sessions, we found a statistically significant increase in decision-making speed, with the speed more than doubling between the first and last game session, indicating growing familiarity with the game interface.

However, the overall error rate of participants increased significantly, possibly due to fatigue or the introduction of more complex financial concepts in higher levels. Additional analysis of the initial decisions at each level …

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 …

crucial data for subsequent steps in the pipeline. In the context of Digital Democracy,
upleveling is when humans verify, correct, and annotate the transcript results after
the legislative hearings have been automatically transcribed. The upleveling process
is done with the …

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 …

Effects Of Temperature On Economic Preferences: A Cross-Cultural Laboratory Study Of Prosocial Behavior, Nikita Tkachenko

Master's Theses

In light of the pressing issue of climate change, our study investigates the implications of rising temperatures on social and economic behaviors through a laboratory experiment conducted among students at university sites in Mexico, India, Kenya, Colombia, and the United States. This paper examines the influence of temperature differences and exposure length on economic decision-making among students at university sites in Mexico, Kenya, and the United States. Analyzing data from the dictator game, we explored how temperature, both ambient and wet bulb, and session length affect prosocial behavior. Our results suggest a link between temperature measures and prosocial behavior, with …

Habitat Characterization Of American Badgers (Taxidea Taxus) Of Northern California, Mitchell Victoria

Master's Theses

American badgers (Taxidea taxus) are a semi fossorial mammal that lives in grassland and open prairie ecosystems as well as coastal prairies, agricultural fields, deserts, and deforested habitats. Many researchers have published work on badgers, but we still require more information on their ecology. The American badger is a semi fossorial, solitary, predatory mammal of grassland ecosystems. They are classified as mesopredators when compared to larger apex predators such as brown bears, wolves, and pumas. However, when larger carnivores are absent, Badgers become apex predators of their ecosystems. Los Vaqueros Watershed in Brentwood, California, was my study site because badgers …

Use Of A California Wetland: Harbor Seal (Phoca Vitulina) Haul-Out Patterns In Elkhorn Slough, Emma Nicholson

Master's Theses

This project investigated small-scale habitat use patterns of harbor seals (Phoca vitulina). The goals were to provide an updated overview of the harbor seal population in Elkhorn Slough, California, USA, identify haul-out areas that are seasonally relevant for pupping and molting, and analyze environmental factors that may influence the harbor seals’ abundance and distribution in the slough. Seal counts were conducted by Elkhorn Slough volunteers throughout the entire slough June 2020-May 2023. Additional survey data at the 5 most populated haul-out sites were collected by volunteers from MLML April 2022-May 2023. A comparison to harbor seal abundance data from 1991-1992 …

Unveiling The Cognitive Impact: An Exploratory Study On Food Insecurity And Value-Driven Attentional Capture, Nichole S. Hogoboom

Master's Theses

Food insecurities have been shown to lead to serious negative health outcomes such as increased risk for diabetes and obesity in adulthood, food-related mental health and behavioral issues, all of which can have a crossover effect in many areas of a person’s life. This experiment explores whether previous history of food insecurity is associated with how people allocate attention to pictures of food; whether they are prioritizing or ignoring food stimuli in their environment. We hypothesized that the severity of food insecurity experienced in childhood would correlate with attentional bias towards food images, and that how hungry or thirsty participants …

The Watchmen In The Song Of Songs: An Intertextual Study, Gabriel Xavier Del Valle

Master's Theses

Problem

The watchmen are a shocking feature in the Song of Songs that have received limited exploration and research. Their dual nature in the Song of Songs is illustrated by their two responses to the women in the song; benign indifference illustrated in Song of Songs 3:1-5 and hostility exemplified in Song of Songs 5:2-8. This has led to a myriad of interpretations regarding their function and identity; however, none have been subject to a thorough examination. The watchmen have not been previously investigated as a potential metaphorical or symbolic representation of the brothers related to the woman in the …
