Lithium Extraction In Chile, Estrella Pallares Medina

Student Theses 2015-Present

This article examines the environmental, political, and economic dimensions of lithium mining in Chile's Atacama Desert, a critical site within South America's "Lithium Triangle." Chapter 1 utilizes both quantitative and qualitative data to introduce the environmental problems of water shortage, ecosystem stress, and biodiversity loss associated with lithium mining, presented within the framework of the ecosystem services approach. This approach categorizes the impacts into four categories: supporting, regulating, provisioning, and cultural, which affect both human and ecological well-being. Chapter 2 applies the academic field of political ecology to analyze how corporate accountability, government policy, and governance shape environmental performance and …

Isolated By Design: An Analysis Of The Texas Energy Grid, Samantha Prado

Student Theses 2015-Present

This paper examines how climate change impacts Texas’s energy grid and identifies strategies for building grid resilience by focusing on renewable energy solutions and the inclusion of marginalized groups in decision-making processes. Understanding the conditions that led to the 2021 energy crisis and how they continue to impact Texas residents is critical in advocating for policy reform and climate adaptation. Therefore, the paper begins with the grid’s failure during Winter Storm Uri in February 2021 to demonstrate how the crisis resulted from extreme weather, market design, policy choices, and inadequate infrastructure. Chapter One analyzes the environmental impact of generating electricity …

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 …

Associations Between Levels Of Physical Activity And Cognitive Health, Gemma Goldenbaum

Honors Theses

The purpose of this study is to examine the relationship between physical activity levels and executive function, specifically focusing on inhibitory control and working memory capacity. Though the benefits of exercise on brain health are well-documented, the extent of cognitive differences between sedentary individuals and elite student-athletes remains misunderstood. Eighty participants (ages 18–35) were categorized via the International Physical Activity Questionnaire (IPAQ) into sedentary, low, and advanced activity tiers. Participants completed computational assessments, including the Operation Span (OSPAN) task for working memory and Go/No-Go tasks to measure response inhibition and implicit associations. Preliminary results indicated significant differences in sedentary behavior, …

Bio 340 Final Project: Effects Of Zoning On Fish Density Along The Great Barrier Reef, Mary Lamoriello

Biology Student Scholarship

Mary Lamoriello - Environmental Biology '27

Over the years, there have been many marine parks and restricted fishing zones established along the Great Barrier Reef to maintain biodiversity and coral health. The goal of these zones is to create an ”undisturbed” area, where species can flourish. Many different species reside in this reef and play important ecological roles. Parrotfish help maintain coral health by grazing on algae, and the presence of carnivores often indicate a diverse and healthy ecosystem. This project aims to examine the differences in species distribution between zones along the Magnetic Island, by looking at carnivorous and …

Bio 340 Final Project: Rural Population Structure And Food Production Interact To Shape Global Undernourishment, Ava Ripanti

Biology Student Scholarship

Ava Ripanti - Environmental Biology '27

Undernourishment remains a major global public health challenge, reflecting the proportion of a population lacking sufficient dietary energy intake. While food availability is central to food security, undernourishment is also shaped by structural and socioeconomic factors such as population distribution and access to resources. Although rural populations are closely tied to agriculture, they often experience higher food insecurity due to limited infrastructure, market access, and healthcare. Prior research emphasizes that broader determinants, particularly inequality and development, are stronger predictors of undernourishment than agricultural output alone, that food insecurity exists in both rural and urban …

Over the course of one semester, these research techniques were used to explore the practice of creative aging programming through analysis of state-level data, testimonials from participating artists, reviewing literature on the topic of creative aging, and examination of the artwork produced by older adults through these programs. These programs can directly impact the social health of older …

The Data Driven Body, Kimberlyn P. Konen

Departmental Honors & Graduate Capstone Projects

This paper examines how wearable fitness technologies function as persuasive digital tools that shape cultural understandings of health. Through a qualitative rhetorical analysis of popular devices such as Fitbit, Apple Watch, Garmin, and WHOOP, the study explores how interface design, data visualizations, notifications, and marketing materials communicate implicit messages about wellness. Rather than acting as neutral measurement tools, fitness trackers promote specific values, including quantification, discipline, optimization, and self-surveillance. Findings reveal that these devices define health through numerical metrics, encourage consistent productivity, frame wellness as competitive performance, and use emotional feedback to reinforce success or failure. Additionally, marketing imagery promotes …

Doctor of Nursing Practice (DNP) Translational and Clinical Research Projects

Abstract

In recent years, a focus on mental health has moved to the forefront of healthcare. This is especially true when caring for United States military service members. The military spouses of these service members also struggle and suffer from mental health disorders. However, the mental health needs of military spouses often receive insufficient attention. Research shows military spouses are at an increased risk of developing mental health disorders and/or suffering from mental illness. A large contributor is the impact of the military lifestyle and its challenges for these spouses. However, research also reveals there has been minimal effort put …

Bacteriophage Therapy For Klebsiella Pneumoniae: Phage Screening And Efficacy Assessment In Macrophages/Neutrophils And Mouse Model, Mounika Duggineni

Biotechnology Theses

Klebsiella pneumoniae causes infections such as pneumonia and urinary tract infections, necessitating alternative therapies. As an emerging MDR pathogen, evaluating newer therapeutic strategies is essential. This study utilized bacteriophages and Klebsiella pneumoniae strains kindly provided by Dr. John, who previously isolated and characterized broad-host-range bacteriophages from hospital wastewater targeting diverse clinical K. pneumoniae isolates. Among fifteen lytic bacteriophages identified across multiple genera, bacteriophage #418 was selected and purified using ultrafiltration, yielding higher functional titers than PEG-based methods. In vitro assays showed Bacteriophage #418 nearly killed bacteria after 2 hours of co-incubation. Ex vivo studies using healthy donors human macrophages …

Caladrius: Creating A Playable Game Via A Multimedia Experience, Isabelle Morgan Brookshire

Whittier Scholars Program

Caladrius: Creating a Playable Game via a Multimedia Experience hones in on making an experience through different forms of media to represent a game. If this project was fully funded and done, it would be a video game on Steam with an art exhibition, small poetry book, and novel accompanied with it. It would even have a show, a soundtrack, and merch. But at this level, it was to make an experience for my audience that they could experience whether or not they enjoyed video games as a concept. I wanted them to enjoy 'playing' within a physical exhibition and …

Emaldi Ms And Oligonucleotide Analysis, Manoj Perera, Yipeng Yin, Reed Arneson, Fakhira Razzaq, Rishabh Awasthi, William Wittstock, Yinan Yuan, Shiyue Fang

Michigan Tech Publications

Enhanced matrix assisted laser desorption ionization mass spectrometry (eMALDI MS) refers to MALDI MS in which the efficacy of desorption and ionization is enhanced by heat, volatile species, or both, generated from chemical decomposition of additives in the sample of analyte under MALDI conditions. MALDI MS has been widely used for oligonucleotide (ON) analysis. However, two challenges, limited ability to analyze long ONs and low tolerance to trace salts, significantly restrict its applications. We recently proposed the ion pair thermal model for the gas phase ion formation mechanism of MALDI MS. This model predicts an exponential increase in ion yield …

A Function-Based Performance Management Intervention To Increase Clinical Documentation Timeliness Among Aba Providers, Alexander Arevalo

Doctoral Dissertations - College of Arts and Sciences

Despite its direct consequences for billing integrity, regulatory compliance, and continuity of client care, clinical documentation timeliness has received limited empirical attention in the applied behavior analysis (ABA) performance management literature. This study evaluated a Performance Diagnostic Checklist-Human Services (PDC-HS)1.1–guided function-based performance management intervention to increase on-time clinical documentation submission among Board Certified Behavior Analysts® (BCBAs) in a home-based ABA agency. The PDC-HS 1.1 identified consequence-based supports as a possible indicated intervention. The intervention was delivered entirely within existing supervisory routines, without monetary incentives, and produced substantial and sustained improvements across an extended observation period. Social validity ratings were positive. …

Photo Identification On Interactions Between Tursiops Trucatus And Humans To Promote The Importance Of Sustainability, Julia Bronneberg

Undergraduate University Honors Capstones

The Mediterranean Sea is one of the most biodiverse regions, and especially around the Maltese islands, a popular tourist destination where people come to enjoy the beautiful weather and blue waters. Because bottlenose dolphins (Tursiops truncatus) are the most common species people see in coastal areas, they are the primary focus of this research. We care about these bottlenose dolphins because they cannot protect themselves if we are the ones accidentally causing them harm. This study starts from the belief that if we cannot protect the ocean and marine life, then we cannot protect ourselves. We use many resources that …

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 …

Soil Conditions Impacting Geothermal Plant Communities In Yellowstone National Park, Karina Nordwald

Honors Theses

Soil acts as the foundation for a productive and functioning environment, by supporting plant life. Abiotic factors drive soil health and consequently influence vegetation. Geothermal activity affects vegetation through strong environmental filters from harsh conditions. Hydrothermal features in Yellowstone National Park represent a variety of naturally occurring extreme environments, where each hot spring ranges in temperature, pH, and overall chemical composition. This study investigates how these environmental drivers dictate vegetation communities, by focusing on the transition zones between geothermal activity and distance from the feature that moves toward increasingly “favorable” environments. By observing a variety of features throughout Yellowstone, we …

Geochemistry And Occurrence Of Rare Earth Elements In Mine-Impacted And Natural Waters Of Montana, Matthew Vitale

Honors Theses

The occurrence and geochemical behavior of rare earth elements (REEs) in mine-impacted and natural waters of Montana are evaluated across a range of environments, including hard rock mining-impacted systems, coal-associated waters, and naturally occurring acid rock drainage (NARD). Understanding the abundance of REEs in secondary sources such as mine-impacted waters is critical for both environmental assessment and resource recovery. A comprehensive dataset of dissolved and total recoverable REE concentrations was analyzed to assess the influence of pH, total dissolved solids, and geologic setting on REE mobility and distribution. Results demonstrate a strong inverse relationship between pH and REE concentrations, with …

Purpose: To implement and evaluate a nurse-led planned extubation safety bundle designed to improve nurse preparedness, interdisciplinary communication, workflow consistency, and confidence during planned extubation events in a pediatric Cardiac Intensive Care Unit (CICU).

Background: Planned extubation in critically ill pediatric cardiac patients requires effective interdisciplinary coordination. Variability in nurse preparation, communication, and knowledge of sedation pharmacokinetics contributed to workflow inefficiencies and patient safety concerns. Evidence supports standardized nurse-led protocols to improve extubation readiness and reduce practice variability.

Methodology: A prospective pre-post quality improvement project was conducted over eight weeks in a pediatric CICU. The intervention included a nurse-led planned …

Development And Launch Of Abn: An Adventist Freelance Web Application, Abishur Moses-Pakkianathan

MS in Computer Science Project Reports

The Seventh-day Adventist community often relies on personal networks and word-of-mouth for Adventist business services. Many of these businesses meet and provide services to their clients primarily through church connections and community recommendations. As the community and businesses grow, traditional networking methods become increasingly difficult to maintain. General marketplaces lack the trust framework shared by Adventists, and faith-based directories are often static or outdated without booking capabilities. Our solution provides a reliable and modern platform for Adventists to create service listings, receive and manage bookings, and connect with faith-aligned clients.

Taxidermy And Technology: A History Of Climate Change Exhibitions At American Museums Of Natural History, Laura Haushalter, Amy Woodson-Boulton

Honors Thesis

My research is on the history of temporary and permanent climate change exhibitions at natural history museums in the United States. My primary research question is: How have natural history museums responded to human-caused environmental destruction through their exhibitions, and what, if anything, are natural history museums doing now to address our current environmental crisis? My research begins with a historiography of natural museums and examines how early 20th-century museums responded to a sense of environmental crisis and widespread threats of species extinction. In the early 20th century, museums shifted from Victorian-era glass cases to modern and artistic dioramas that …

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 …

“The Right Of Black Folk To Love And Enjoy”: Black Romanticism, Pleasure, And Poetics, 1900-1920, John D. Hadlock

Electronic Theses and Dissertations

This dissertation explores poetry written at the turn of the twentieth century in order to closely examine what I call the “Black Romantic” impulse of the Harlem and New Negro Renaissances. I argue that Black American poets turned to a Romantic notion of the poet as cultural representative and of poetry as a radical celebration of beauty that disavowed and disputed social ills, namely racist ideologies in America, while simultaneously demanding the right of Black pleasure-taking. However, I also contend that Black American poets of various backgrounds and identities used different poetic, rhetorical, and artistic strategies to elevate the status …

Navigating Barriers: The Career Challenges Of Chinese Non-Stem Graduates In The U.S. Job Market, Dilin Li

Electronic Theses and Dissertations

This qualitative phenomenological study explored the career challenges faced by Chinese international graduates from non-STEM fields as they transition from U.S. higher education to the job market. While prior research has largely focused on STEM graduates who benefit from favorable visa policies and high labor demand, limited attention has been given to non-STEM students navigating structural, cultural, and social barriers to employment. Guided by the intellectual capital framework—which encompasses human, cultural, and social capital—this study examined how Chinese non-STEM graduates experience and respond to these barriers within the intersecting contexts of immigration policy, labor market expectations, and cultural adaptation.

Autism In Real Life: Performance As Pedagogy And Advocacy, Paula Horton

Honors Theses

This thesis examines how autoethnographic performance can function simultaneously as public pedagogy and disability advocacy through the analysis of Autism in Real Life, a solo performance created and staged at Southern Illinois University Carbondale. Drawing from performance studies, psychology, sociology, and disability studies, the project explores how embodied storytelling communicates autistic lived experience to audiences unfamiliar with autism. The performance combines narrative, humor, direct audience address, visual media, and accessibility-centered theatrical design to move beyond clinical representations of autism and toward a relational understanding grounded in neurodiversity and the social model of disability.

Using an autoethnographic performance methodology, this thesis …

From Farewell To Fáilte: The Voices Of Iowa’S Irish Daughters, Katie Hermanson

History Theses, Dissertations, and Student Creative Activity

Irish women’s immigration to Iowa brought rich culture and lasting impacts, despite their contributions being silenced by history. Women left Ireland for economic opportunity and education abroad to support their impoverished families. Millions emigrated between 1830 and 1915, spreading across the world. The Irish women who came to the United States encountered discrimination and cultural stereotyping as they worked in domestic service, developed religious orders, taught school, owned businesses and raised families. Women bore the burden of supporting their families in Ireland by sending remittances home and communicating between countries. Their cultural identity as exiles dwelled in guilt for leaving …
