The Legacy Of Lead: Lead Exposure's Harmful Effects And Its Concentration In Poc Communities, Layla Sophronia Barber

Student Theses 2015-Present

This thesis examines the disproportionate burden of lead exposure carried by low income, POC communities. The systemic nature of this problem is a symptom of a longstanding legacy of environmental injustice in the United States. Decades of federal neglect are reflected in the higher statistics of lead exposure and poisoning in predominantly black communities. While it is understood that lead exposure poses a serious threat to physical health and early cognitive development, there is a discouraging lack of urgency to remove the toxin from non-wealthy communities. The material covered by this thesis aims to identify and correct the discriminatory social …

It is of global interest to remediate these issues for the betterment and progress of society, and thus, an approach to addressing these complications collectively and comprehensively is of utmost importance. This paper investigates …

Secondhand Or Second-Class? Environmental Injustice In Global Textile Waste Trade, Wendy S. Escalante

Student Theses 2015-Present

This paper addresses the issue of textile waste dumping, specifically how secondhand clothing exports from the Global North create environmental, social, and public health burdens in the Global South. The study focuses on case studies in Chile’s Atacama Desert, where shipments of used clothing overwhelm local waste infrastructures and worsen patterns of environmental injustice. Chapter 1 describes the global flows of textile waste, including trade volumes, landfill accumulation, and the impacts of discarded clothing on ecosystem services such as clean water, fertile soils, and breathable air, alongside health risks from microplastic pollution, toxic runoff, and respiratory hazards from textile fires. …

A Sturdy Future: Mangrove Restoration Against Climate Extremes, Gabriella Marie Siasoco

Student Theses 2015-Present

This paper addresses the impacts of climate change on natural disasters and examines how rehabilitation of mangrove forests in Mesoamerica and the Caribbean can mitigate those effects. Rising ocean and atmospheric temperatures contribute to higher sea levels and more severe hurricanes and tropical storms, characterized by increased frequency, duration, and intensity in peak winds, storm surges, and rainfall. Mangrove ecosystems act as vital buffers against coastal disturbances such as tsunamis and extreme storms, while contributing to climate change mitigation through carbon sequestration. Additionally, they improve water quality by filtering nutrients, preventing eutrophication. Despite their ecological and economic value, mangroves in …

Solid Waste Management In Greater Khartoum City, Sudan, Roba Mahmoud

Student Theses 2015-Present

This study investigates the rising solid waste management (SWM) dilemma in Greater Khartoum City (GKC), a critical environmental and public health issue caused by fast urbanization and inadequate infrastructure, with historical linkages to Sudan's colonial and postcolonial growth. Chapter 1 describes the current problem using quantitative and qualitative data, demonstrating that GKC produces approximately 3,340 tons of waste each day, with 56% organic matter, 8% plastics, and 16% paper. Collection efficiency remains severely poor, at 31.5%. Informal recyclers known as Nakasha or Barkata collect approximately 7% of total waste, supporting roughly 3,900 people, whereas filthy open dumps and unsorted medical …

How Open Is Merlot? A Descriptive Study Of Oer Availability In A Major Learning Object Repository., James Thibeault, Jamie Schmidt

Open Educational Resources Publications

The Multimedia Educational Resource for Learning and Online Teaching (MERLOT) has long been regarded as a reputable source of open educational resources (OER). However, this reputation has rarely been subjected to systematic empirical scrutiny. This preliminary descriptive study examines how reliably MERLOT's Business section surfaces OER. Using a browsing-based methodology mirroring typical user behavior, 500 catalog records were manually evaluated across six access status categories. Results indicate that only 134 of 500 sampled resources (26.8%) qualify as OER under a definition requiring both open licensing and immediate accessibility. Of the 315 live links, 42.5% were OER, while 136 records (27.2%) …

Gendered Politics Of Pictures: How Images In A Pakistani English Textbook Homogenize Female Identities, Liaquat Ali Channa

The Qualitative Report

This qualitative multimodal analytical study draws upon Kress and van Leeuwen’s ideas about pictures and problematizes textbooks of English that supposedly teach only English in Pakistan. It aims to understand the identities of an adult female as shown in the images of an English textbook. It uses Foucault’s theories of discourse and discursive formation, and a Vygotskian sociocultural view of the development of consciousness. By following Braun and Clarke (2006, 2019), all the pictures of the My English Book 4 are first analyzed thematically. Later, O’Toole’s (1994) method of analyzing pictures is employed for a detailed examination of a representative …

The guiding research question for this project asks: With the constantly evolving marketing and consumer landscape and regular use of AI agents like ChatGPT or Google Gemini, how can marketing and communication professionals remain relevant? In short, the answer to this question is that integrated marketing communication (IMC) practitioners must adapt to ongoing consumer behavior changes brought on by technology advancements while leveraging a combination of traditional persuasive techniques, a variety of modern marketing …

Please Don’T Kill Big Bird: The Crusade Against Public Broadcasting, Paige Meyer-Draffen

Whittier Scholars Program

The sword and shield conservatives wield in their crusade against the CPB are contradictory constructs that represent the hypocrisy, greed, and monopolistic inclinations that underpin the efforts to kill public broadcasting. The Shield that conservatives stand behind is the rhetorical defenses employed to degrade the institution of Public Broadcasting. Arguments like protecting the American Family in the culture wars from programming like PBS’ Tales of the City (1993), or accusing NPR of being a biased, inaccurate journalistic outlet, and reducing PBS and NPR to only serving “wealthy, white, urban liberals and progressives, who generally look down on and judge rural …

The African American Pulpit And The Reconstruction Of Narrative Ground In The Black Community, Nathaniel Cox

Electronic Theses and Dissertations

This dissertation explores how the African American pulpit serves as a living wellspring for rebuilding stories, memory, and identity, a task made urgent by centuries of erasure, from the trauma of the Middle Passage to the ongoing reverberations of that violence. My central claim is that African American preaching, when viewed through the insight-rich frameworks of Gadamer, Burke, and Frankl, becomes not just a form of speech, but a lifeline. It helps reclaim "narrative ground": the deep roots of meaning, belonging, and shared purpose that nourish a wounded people and allow genuine flourishing.

The journey unfolds across six movements. Chapter …

Homeschool Policy In Mississippi: Perceptions Of Regulations Among Parents, Alumni, And Policy Advocates, Kaley Lecroy

Honors Theses

In recent years, the growth of homeschooling and alternative education methods such as hybrid and virtual schools has reshaped educational opportunities for both parents and students. As more options become available and more parents opt for the flexibility of non-traditional school, it is imperative that we examine the educational guardrails in place for these students. Even more importantly, it is imperative that the perspectives of home educators and homeschool alumni have a place at the table when we review the regulations in place. This thesis seeks to understand the perspectives of current and former Mississippi home educators, Mississippi homeschool alumni, …

Service-Learning In Adapted Physical Activity: Student Experiences With And Without Course Integration, Courtney Jost, Nicole Fiscella Nicole Fiscella, Roxanne Bahn-Bales, Tze-Hsuan Wang, Jennifer Beamer, Jennifer Taylor, Willie Chun Wai Leung

Educational Practices in Kinesiology

Service-learning is widely used in adapted physical activity/education (APA/APE) courses to enhance student learning through community engagement. However, limited research has explored how the presence or absence of an APA/APE course influences students’ perceived learning, confidence, and engagement in inclusive physical activity settings. This quasi-experimental, cross-sectional study examined how course-enhanced and purely experiential models of a university-based APA service-learning program, PA PALS, shaped undergraduate students’ experiences. Students (N = 58) participated; 41.4% (n = 24) were concurrently enrolled in an APA/APE course (course-enhanced group), while 58.6% (n = 34) participated as volunteers (purely experiential group). A validated …

What Do We Owe A Drowning Coast? Examining Louisiana's Coastal Crisis Through The Lens Of Environmental Justice, Owen M. Plaisance

Honors Theses

This thesis argues that human contributions to Louisiana’s coastal land loss constitute a form of environmental injustice that cannot be adequately addressed through frameworks focused solely on aggregate welfare or distributive fairness. While utilitarian and Rawlsian approaches offer important insights, both are limited in capturing the full scope of harm caused by environmental degradation. In coastal Louisiana, land loss undermines not only economic resources and physical security but also the substantive freedoms required for individuals and communities to live meaningful and culturally rooted lives, while disrupting ecological systems and non-human flourishing. To address these limitations, the thesis develops the Capabilities …

Just War Theory And Coercive Non-Proliferation: Ethically Evaluating Nuclear Prevention Efforts, P. Walker Jacklin

Honors Theses

This thesis examines the ethics of coercively addressing non-nuclear states who are attempting to acquire nuclear weapons. Nuclear weapons pose a serious danger on a global scale, so ethical analysis should balance these consequences with the coerciveness of state intervention. Just War Theory provides a useful framework that balances these considerations.  Using the criteria of Just War Theory, this thesis examines two 21st century non-proliferation operations: Operation Orchard and Operation Midnight Hammer. I find that Operation Orchard fails the criteria of Just War Theory, while Operation Midnight Hammer satisfies the criteria. Making this determination is ethically risky, however, because our …

Beyond Religious Narcissistic Identification: Agnostic And Atheistic Narcissism, Magdalena Żemojtel-Piotrowska, Jarosław Piotrowski, Bartłomiej Nowak, Vassilis Saroglou, John Maltby, Constantine Sedikides, Mladen Adamovic, Nur Amali Aminnuddin, Seth Christopher Yaw Appiah, Rahkman Ardi, Zana Hasan Babakr, Einar Baldvin Baldursson, Sergiu Bălțătescu, Muhammed Bilgehan Aytaç, Aidos Bolatov, Bruno Bonfá-Araujo, Matthias Burghart, Phatthanakit Chobthamkit, Marilyn Clark, Magali Clobert, Richard G. Cowden, Jesus Alonso Datu, Sandesh Dhakal, Sonya Dragova-Koleva, Begoña Espejo, Dmitry Grigoryev, Emanuela Gritti, Katherine Gundolf

All Works

Agnosticism and atheism are often grouped simply as nonreligious identities, yet emerging research highlights their distinct psychological profiles and social implications. Among these distinctions, collective narcissism–characterized by strong attachment to one’s group, exceptionalism, and grievance for recognition–offers a framework for understanding identity processes in both nonreligious groups. We examined whether agnostics and atheists exhibit collective narcissism and its forms (agentic–focused on exceptional effectiveness; communal–focused on exceptional morality) similarly to believers. We explored cross-denominational variance in agentic and communal collective narcissism levels relying on data from 77 countries (N = 3,570; 1227 agnostics, 2343 atheists). Agnostics and atheists from secular countries …

Monitored Natural Attenuation Evaluation And Additional Characterization Of A Ccr Unit Lithium Groundwater Plume, Matt Barickman, Adam Piestrzeniewicz Pg

World of Coal Ash Proceedings

Monitored Natural Attenuation (MNA) refers to the reliance on natural attenuation processes (within the context of a carefully controlled and monitored site cleanup approach) to meet groundwater protection standards (GPS) for a CCR unit within a reasonable time frame (USEPA, 1999). MNA is being evaluated as an adaptive management strategy for a CCR unit groundwater plume with statistically significant lithium concentrations above GPS, though with little risk of offsite migration. A previous MNA evaluation was performed for the lithium plume following the United States Environmental Protection Agency (USEPA) “tiered lines of evidence approach” (USEPA, 2015), which determined that there were …

Empirical Results From The Eliminations Of Municipal Minimum Parking Requirements, David A. Griffith

Honors Theses

Minimum Parking Requirements (MPR) are municipal zoning ordinances mandating a set number of off-street parking spaces for new developments. Since the 1950s, MPR has been the near-universal way American municipalities supply parking, though growing criticisms since the late 1990s have targeted the policy for distorting development patterns, imposing high costs, and subsidizing personal vehicle use. Beginning in the early 2010s and increasingly in the early 2020s, cities and counties across the United States have moved to reform or eliminate MPR. This paper is the first empirical study of the economic effects of these removals. Using a two-way fixed-effects difference-in-differences OLS …

Lifestyle And Activity Patterns Of The Classic Period Maya From Chac Balam And San Juan, Ambergris Caye, Belize, Abigail L. Hornbeck

Honors Theses

Bioarchaeological research often uses skeletal remains to reconstruct patterns of activity and labor in past populations. This study examines potential sex-based differences in long bone morphology among individuals from the Classic Maya sites of Chac Balam and San Juan on Ambergris Caye, Belize. These coastal communities participated in maritime trade networks, and daily activities such as cargo transport, canoe travel, and fishing may have placed distinctive mechanical stresses on the skeleton. The goal of this study was to evaluate whether measurable differences in bone structure between males and females reflect differences in habitual activity patterns.

Two complementary methods were used …

Assessing College Tuition And Wage Prospects For Careers In Archaeology, Angelina H. Gutierrez

Honors Capstones

The pressures of rising college tuition are raising questions about whether a degree in higher education is worth the return on investment in today's society and economy. This study aims to acknowledge the issues of affording college and the opportunities granted in the face of college wealth premiums from the perspective of the field of archaeology. The college wealth premium is understood as additionalopportunities and increased salaries offered to those with a degree in higher education compared to those without. Using the Midwestern United States as a case study, I discuss the gender/race wage gap, college debt, loan inequity, and …

Using Geospatial Analysis and Machine Learning to Compare Metropolitan Greenspace and Rates of Adolescents with Obesity

 Rachel Schild MD | DenYelle Kenyon PhD

 Introduction: Insufficient outdoor activity, influenced by limited access to exercise-friendly greenspaces, may contribute to increasing childhood obesity rates. However, rigorous evaluation of greenspace quality on a citywide scale is lacking. This study aims to characterize greenspace vegetation types and correlate them with adolescent obesity outcomes, identifying optimal characteristics for promoting health. This data could aid city planners in optimizing greenspace allocation and improving vegetation choices.

Methods: Satellite imagery and municipal data were used to map ten cities, …

Expertise First: Reflections On Informal Artificial Intelligence Mentoring In An Asynchronous Nursing Faculty Community, Anna Liza D. Villena Phd, Rn, Fnp-Bc

Journal of Online Mentoring

The integration of generative artificial intelligence (AI) into higher education has arrived faster than the support structures designed to help faculty navigate it. This article reflects on one faculty member’s experience providing informal AI integration mentoring to nursing colleagues at Walden University, a fully asynchronous online graduate nursing program, where clinician-educators with deep disciplinary expertise often struggled to recognize that expertise as an asset in their interactions with AI tools.

Drawing on Rogers’ (2003) diffusion of innovations theory, the article describes the mentoring approach that emerged from practice, the central insight that faculty are not failing to integrate AI because …

The Ethical Imperative Of Public Health Institutions To Protect The Reproductive Autonomy Of Vulnerable Populations, Kennethea Wilson

Electronic Theses and Dissertations

This dissertation establishes the ethical responsibility of public health institutions to safeguard reproductive autonomy, especially among vulnerable populations. While reproductive decision-making is traditionally framed within individual clinical encounters, this work contends that reproductive autonomy is fundamentally a matter of public health ethics. Socioecological determinants, including social, legal, environmental, and structural factors, often constrain individuals’ ability to make meaningful reproductive choices, leading to preventable harm.

Reproductive autonomy is defined as the capacity to make informed decisions about whether and when to conceive, as well as how to parent. The dissertation critiques the sufficiency of clinical ethics frameworks, such as informed consent …

Quantitative Assessment Of Cybersecurity Risk Variability Across Transportation Modes, Paulo Carreon

Doctoral Dissertations and Master's Theses

Transportation systems are increasingly dependent on digital technologies, networked communications, and cyber-physical integration, making cybersecurity an important issue for operational continuity, resilience, and safety. Although cybersecurity risks in transportation are widely recognized, much of the existing research remains mode-specific and lacks a standardized quantitative framework for comparing risk across transportation systems. This study develops a quantitative, incident-based approach for assessing cybersecurity risk variability across four major transportation modes: Aviation, Maritime, Rail, and Road. The study is based on a manually constructed dataset of 189 publicly reported transportation cybersecurity incidents collected from 2000 to 2025. Each incident was coded into structured …

Pop Prophets: How Celebrity Culture Shapes Gen Z'S Worldview, Olivia G. Usie

Honors Theses

Generation Z has grown up in a social environment shaped by constant connectivity, digital communication, and immediate access to the lives of others. Because of this, celebrity culture and pop culture may play a larger role in shaping attitudes, behaviors, and identity than they did for previous generations. This study explores how celebrity culture shapes Gen Z’s worldview through four areas: pop culture, celebrity, herd mentality, and cancel culture.

A mixed-method approach was used. Quantitative data was collected through a 28-question survey of 202 participants ages 18–25. Qualitative data was gathered through one focus group of eight participants and three …

Hotspot Analysis Of Nitrate And Arsenic Concentrations In Minnesota Well Water, Jadyn Keeler

Arts & Sciences Undergraduate Showcase

Water contamination is one of the biggest threats to water supply and can have long term human health consequences. It is key to identify vulnerable regions to develop better management strategies. This project utilizes hotspot and outlier geospatial analysis to locate areas across Minnesota with elevated levels of nitrate and arsenic in well water and better understand potential factors that might be influencing this. Statistically significant hotspots and cold spots were identified with up to 99% confidence. Hotspots of nitrate were located mainly in the south-central region while hotspots of arsenic were located primarily in the western and south-central portions …

Storytelling As A Pedagogical Tool For Improving Memory In Lectures, Sydney E. Rutter

Honors Theses

The purpose of the study was to examine if utilizing storytelling in lectures caused a positive effect on students' memory over a week-long period. Storytelling has been used as a mnemonic device to improve memory, however its benefits have not been experimented much in higher education. In this study, 53 undergraduate psychology students were placed into two groups: traditional lecture or storytelling lecture. Students then watched the lecture they were assigned, both lectures discussed the ASURE model. A week later, students returned and took a 17 question memory test.
