Flood Resilience Through Working-Land Conservation: Assessment Of Wetland Inundation Dynamics Across Wrp, Wma, Wpa, Padus And Crp Lands In Nebraska (2018–2024), Pranjay Joshi

Community and Regional Planning Program: Theses

This study first confirms whether Nebraska’s wetlands are still functioning hydrologically in ways that reduce flood impacts. Wetlands are known to lessen flood damage by storing water, slowing runoff, and moderating peak flows, but these benefits depend on the wetlands’ ability to maintain inundation and saturation through time. Many wetlands across the state have undergone drainage, hydrologic alteration, or isolation from surrounding watersheds, raising uncertainty about their present-day functioning. Using seven years of Sentinel-2 imagery processed in Google Earth Engine, this research establishes a clear, long-term record of inundation patterns across thousands of wetland parcels. This analysis verifies which wetlands …

Telford, Tennessee: The Evolution Of An Agrarian Community, Jeffrey D. Banks

Master of Arts in Appalachian Studies Applied Projects

This qualitative paper explores the overlooked history of Telford, Tennessee, a small unincorporated Appalachian community confronting the erosion of its distinctive identity. Drawing from oral history interviews with lifelong elder residents and newly unearthed archival materials, the study complicates the prevailing narrative of 20th-century decline. Instead, it reveals a more nuanced evolution, where diminished local commerce and fading social cohesion were offset by expanded regional access and emergent forms of civic engagement. Among the study’s most significant discoveries is the rediscovery of Franklin Academy--a nearly forgotten 19th-century institution whose advanced debates on Native American rights illuminate an unexpectedly progressive intellectual …

From Quid Post Quo To Quid Pro Quo: Toward An Evidentiary Standard For 18 U.S.C. § 666 After Snyder, Luke Henkel

University of Chicago Law Review

This Comment addresses a question left unanswered by the Supreme Court’s recent decision in Snyder v. United States. Snyder held that the federal funds bribery statute, 18 U.S.C. § 666, covers only bribes, not gratuities. That is, an agreement to exchange payment for an official act by a state or local government official is criminally prohibited (if the official’s agency receives a certain amount of federal funding). But § 666 does not prohibit payments made after official acts so long as there was no agreement to conduct a quid pro quo exchange beforehand. Thus, the key issue in cases with …

Pardoning Corporations, Brandon Stras

University of Chicago Law Review

In 1977, a company convicted of conspiring with the mob asked President Jimmy Carter for a pardon. Government officials speculated that the President could grant the request, but ultimately the President decided that the company did not deserve clemency. Nearly fifty years later, President Donald Trump pardoned a company and commuted the sentence of another. People are again wondering whether the pardon power covers companies, but no one can offer evidence either way.

History shows that the pardon power covers companies. Before the Founding, the King would often pardon corporations. Both the City of London and the Massachusetts Bay Company …

Sincerity Or Substantial Burden? Investigating The Proper Threshold Test For Prisoner Free Exercise Claims, David Wang

University of Chicago Law Review

When prison officials violate the free exercise rights of prisoners, prisoners can seek recourse under 42 U.S.C. § 1983. However, due to the specialized and restrictive nature of prisons, courts adjudicate these claims under a reasonableness test set out in the case Turner v. Safley instead of under a strict scrutiny standard. While circuits agree on using the Turner test for prisoner free exercise claims, there is a deep circuit split on the proper threshold test for these types of claims.

While some circuits hold that inmates need to show that their religious practice was substantially burdened, other circuits hold …

Effect Of Successive Subculturing On Virulence, Growth, And Germination Of Fungus Metarhizium Rileyi For Biological Control Of Fall Armyworm, Joanna Marie E. Valeros, Trisha Anne P. Garcia, Noel G. Sabino, Marcela M. Navasero, Melissa P. Montecalvo

The Philippine Agricultural Scientist

This study explored the impact of successive subcultures of Metarhizium rileyi (Farl.) Kepler, S.A. Rehner & Humber on its cultural traits, spore germination, and virulence against fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), a key pest in agricultural systems. The mass production of infective propagules is essential for effective biological control. Notable changes were observed in the texture and mycelial appearance of the fungus across subcultures. Initially, the fungus exhibited a powdery texture up to the 6th subculture. However, the fungal growth became fluffy and cottony by the 8th and 10th subcultures. Additionally, sporulation rates (7.05 × 10^{8 …}

Application Of A Nonprofit Project Management Methodology To Solid Rock Bible Camp Infrastructure Planning, Austin Laber

Student Projects for Graduate Degrees

Over the last decade, several costly infrastructure issues have been presented to Solid Rock Bible Camp (SRBC) due to deferred maintenance, poor record-keeping, and short-term, donation-based funding. This has cost the organization substantial time and money and has risked its ability to obtain insurance for its infrastructure. The application of project management principles to SRBC’s unique nonprofit structure and values identified SRBC's current infrastructure needs, pursued future infrastructure solutions, and prioritized future project recommendations. This project documented the campus’s current state and compared its inventory to industry standards and the needs of its stakeholders to find deficiencies. These deficiencies were …

Evaluating Intersectional Variation Of Hpv-Associated Cancers In Rural America, Jason Semprini, Gabriel A. Benavidez, Whitney E. Zahnd, Heather M. Brandt

Public Health

Purpose: For decades, incidence of human papillomavirus (HPV)-associated cancers has been increasing in rural communities across the United States. Although emerging evidence shows a widening rural-urban disparity, rural intersectionality has been understudied. Our study examined the incidence of HPV-associated cancers within rural communities to identify differences by race/ethnicity for males and females, and explore how these differences varied by cancer type, socioeconomic, and geographic factors.

Methods: We accessed age-adjusted cancer incidence rates (2010–2019) from the North American Association of Central Cancer Registries (NAACCR) for HPV-associated cancers (cervical, vaginal, vulvar, penile, anal, oropharyngeal) in rural counties. Stratifying by sex, we calculated …

Earnings, Ethics, And Fast Fashion: How Does Income Affect Consumers’ Decisions?, Ava M. Minton

All Theses

This thesis examines if annual earnings influence consumers’ likelihood of avoiding clothing brands associated with labor exploitation. To examine this question, the study draws on four major U.S. datasets that together capture two decades of consumer attitudes and self-reported behaviors. The results show that income has a strong and statistically significant effect: household income increases the odds of avoiding exploitative brands by roughly 27 percentage points. Education, ideology, and gender also exhibit meaningful positive associations with ethical consumption, while age slightly reduces the likelihood of boycott participation. Overall, the analysis provides evidence that ethical consumption behaves like a normal good …

Privacy Preserving-Based Artificial Intelligence For Precision Agriculture, Partha P. Sengupta

Dissertations

The research work finds a solution to precision agriculture of cotton cultivation using artificial intelligence (AI) models. Two sets of model performance based on the application are selected namely a low resource and a high resource setting. This is because using drone surveys to capture images identifying the classes of stressed and unstressed cotton plantation requires limited model architecture and CPU based computation. Thus, traditional AI models were selected for low resource settings. Again, for high computation intensive models like transfer learning-convolution neural network (CNN) based architectures were grouped into high resource settings. There was another issue of class imbalance …

Herein, demonstrates the use of the malonate template to establish a synthetic route to both 2-thiohistidine and 2-thio-3-N-methyl-histidine from a benzyl methyl malonate derived intermediate. Furthermore, efforts exploiting the applicability of the malonate template for the of both 2-thiohistidine and 2-thio-3-N-methyl-histidine as a suitable alternative to methods previously described by Erdelmeier are described.

The method presented incorporates modifications to the biomimetic pathway described by Erdelmeier for the synthesis of 2-thiohisidine. By exploiting the biomimetic formation of 2-thiohisitidne’s mechanism via mass spectrometry, we …

Understanding Crystallization Behaviors Of Polyethylene-Derived Vitrimers, Sara Valdez

Dissertations

Polyolefins (POs), particularly polyethylene (PE) and polypropylene (PP), are among the most widely utilized polymers globally, valued for their low production costs and favorable mechanical properties stemming from their semicrystalline microstructure. However, their extensive use and improper disposal have raised serious environmental and human health concerns. In response, PO-derived covalent adaptable networks (CANs) have emerged, integrating dynamic chemistries to enable recyclability and sustainable end-of-life strategies. While existing literature has largely focused on novel CAN systems, structure–property relationships, and network rearrangement in relation to thermal transitions (e.g., topological freezing temperature), the influence of network formation on crystallinity and crystallization kinetics remains …

Impact Of Community College Size And Meeting Types On Leader-Member Conversation Quality In Career And Technical Education (Cte) Leaders: A Mixed Methods Study, Kenneth Wayne Kirkland Jr.

Dissertations

Community colleges are complex institutions with the primary mission of workforce preparation and academic transfer. In many cases, community colleges produce the majority of their local workforces. Political influences upon workforce priorities, increased national calls for transparency in higher education training, complicated infrastructure, and technical expertise requirements for faculty have created substantial challenges for career and technical education (CTE) leaders. These complexities require the 21st-century CTE leader to be as externally focused as their presidents, highlighting the importance of communication effectiveness in both leaders.

The purpose of this mixed-methods study was to investigate the influence of community college enrollment levels …

Sight-Singing Requirements Of Choral Festivals: A Fifty-State Comparison Of The Methods Used To Adjudicate Ensemble Literacy, William Griswold Jr

Dissertations

Standardized testing in the United States has permeated all levels of education including the choral music classroom. Across the country, state music organizations have implemented yearly evaluations of high school choral ensembles in which directors prepare choirs to be judged against a particular standard. While many organizations utilize similar methods of evaluating performances at adjudicated choral festivals, the methods used for evaluating sight-singing vary greatly from state to state. Throughout the country, various types of rhythmic, melodic, and harmonic exercises are used to evaluate an ensemble’s ability to sight-sing, however in certain states no form of sight-singing is required for …
