Neonicotinoid Bioaccumulation In Bluegill And Bullhead Within Lake Julia And Lake Zumwalde, Jake Stuber

Journal of Earth and Life Science

Brown Bullhead Ameiurus nebulosus, Yellow Bullhead Ameiurus natalis, and Bluegill Lepomis macrochirus are unique in their stark differences. Bullhead are scaleless bottom feeders that can tolerate high pollution and low O₂ conditions. In contrast, Bluegill are scaled, aggressive nesters and are less tolerant of high pollutants or low-oxygen conditions. Among these pollutants include a class of chemicals called neonicotinoids (hereafter referred to as neonics). Neonics are a class of insecticides primarily used within agriculture and pest management. Due to the effectiveness, application has escalated on a global scale. They have been well documented by many toxicology assessments. …

Comparison Of Calcified Structures To Estimate Ages Of Northern Pike Esox Lucius In Various Lakes, Kaed Rauk

Journal of Earth and Life Science

Northern pike Esox lucius are a dominant predatory fish in many aquatic systems. They can have significant impacts on the ecosystems they inhabit and are also a popular game fish among anglers. However, northern pike are a difficult species to age accurately. This study aimed to compare calcified aging structures to identify trends and determine which structure provides the most accurate age estimates. A total of 119 northern pike were sampled, and multiple structures from each fish were independently aged by two readers. The coefficient of variation (CV) was calculated for each structure to assess precision. Sectioned sagittal otoliths exhibited …

Indigenous Land Seizure & Environmental Injustice: Impacts Of Settler Colonialism, Lydia Moorman

Journal of Earth and Life Science

The fields of conservation and environmentalism prioritize ecosystem health, yet both emerged from western frameworks that displaced and criminalized Indigenous land stewardship. The idealization of “pristine wilderness” narratives served to justify the removal of Indigenous peoples from their homelands and erased millennia of sustainable land stewardship that had maintained ecological balance long before western conservation existed. These narratives not only misrepresented Indigenous relationship with land but also constructed a false dichotomy between humans and nature that positioned Indigenous presence as a threat rather than a source of ecological knowledge. Simultaneously, anthropogenic expansion; such as pipelines, mining, railroads, and other extractive …

Powering The Machine, Draining The Planet: Whether U.S. Environmental Law Is Equipped To Regulate The Energy And Water Demands Of Ai Data Centers, Michael Marcu

Journal of Earth and Life Science

Artificial intelligence (AI) data centers have become one of the United States' fastest-growing and least-regulated sources of environmental stress. In 2024 alone, U.S. data centers consumed 183 terawatt-hours (TWh) of electricity more than the entire nation of Pakistan and consumed an estimated 17 billion gallons of water (IEA, 2025; Berkeley Lab, 2024). By 2030, electricity demand from these facilities is projected to reach 426 TWh, a 133% increase in six years (Pew Research Center, 2025). This paper examines whether the existing U.S. environmental regulatory framework put by the National Environmental Policy Act (NEPA), the Clean Water Act (CWA), and the …

Western Journal of Orthopaedics

Distal adding-on (DAO) is a complication of spinal fusion characterized by postoperative deformity progression distal to the fusion construct. DAO after posterior spinal fusion for adolescent idiopathic scoliosis (AIS) is variably defined and inconsistently managed. This scoping review synthesizes evidence on DAO detection, management, and outcomes. A PRISMA-ScR–guided search identified relevant studies. Thirty-one studies (2,998 patients; median follow-up, 30 months) met inclusion criteria. Reported DAO incidence ranged from 3.5% to 62.5%, reflecting heterogeneity in definitions, patient factors, surgical constructs, and follow-up duration. Revision surgery was infrequent and typically delayed. When performed, it was most often prompted by progressive coronal decompensation …

Fibula Strut Allograft With Proximal Tibia Autograft For Treatment Of Humerus Nonunion: A Case Report And Review Of Oligotrophic Nonunion Management, Paul Wilson, Naomi Kelley, Samer Kakish

Western Journal of Orthopaedics

Due to their high incidence and frequent need for reoperation, nonunions of the humerus present a significant challenge in orthopaedics. Using fibular struts to treat nonunions have demonstrated excellent results. While fibular autografts provide both biologic and structural benefit, high donor site morbidity must be considered. Although their application in midshaft humeral nonunions remains limited, fibular allografts avoid donor site morbidity. Enhancing fibular strut allografts with biological components offers a promising strategy for treating fractures that have failed prior revisions. This case study presents a 36-year-old woman with an aseptic oligotrophic midshaft humeral nonunion who had an unsuccessful revision surgery. …

Competitive And Priority Effects Of Native Cool-Season Grasses On Invasive Bromus Species In The Northern Great Plains, Tyler Michael Geltmacher

Electronic Theses and Dissertations

Native grasslands and restoration sites in the Northern Great Plains face pressure from invasive cool-season grass species, such as smooth brome (Bromus inermis) and cheatgrass (Bromus tectorum). Native cool-season grass species may compete in the same niche as the invaders and provide resistance to invasion of existing or restored grasslands. Green needlegrass (Nassella viridula) and junegrass (Koeleria macrantha) were evaluated in this study for competitive effect and priority effect against invasive bromes to inform management decisions. Greenhouse studies were conducted to evaluate competitive ability of the two native species as well as how priority influences competition. In my first chapter, …

Primary Avian Tracheal Cell Models For The Isolation Of Emerging Avian Metapneumovirus Strains, Tricia Serrao

Electronic Theses and Dissertations

The emergence of avian metapneumovirus (aMPV) subgroups A and B in the United States poultry industry has created an urgent need for standardized, host-specific diagnostic platforms. Historically, reliance on continuous, multi-species cell lines has limited the primary isolation of field strains and introduced potential adaptation artifacts. To address these challenges, this research first established and characterized a reproducible primary cell culture system derived from the tracheal tissues of 1-day-old turkey poults. This system was maintained in an optimized DMEM/F-12 formulation supplemented with 5% FBS, EGF, and ITS, with early-passage cultures achieving 90% confluence within 24 to 48 hours. Morphological and …

Finite Mixture Modeling Towards Applications In Material Science And Biomedical Data, Jason Hasse

Electronic Theses and Dissertations

This dissertation contains three chapters on different applications of mixture regression models, broadly in materials science and public health. We begin with a basic application of finite mixture models and regression mixture models. The materials science analysis was performed entirely using data from finite element simulations of the additive manufacturing process via powder bed fusion. Visualization of the clustering solution as applied to the additive manufacturing designs highlighted the intuitive patterns that could be found. These patterns simultaneously yield the regression coefficients and subgroups of the geometric regions, providing a way to predict stresses and strains in a new geometry …

Understanding Motor Competence In Autism And Developmental Coordination Disorder: From Everyday Performance To Underlying Postural Control Mechanisms, Crystal E. Alvarez

Kinesiology Dissertations

Motor competence plays a foundational role in children’s participation, physical activity, adaptive behavior, and overall quality of life. Although motor difficulties are highly prevalent in autism spectrum disorder (autism) and developmental coordination disorder (DCD), these challenges are frequently under-identified and insufficiently characterized, particularly in autistic populations. Existing research demonstrates substantial overlap in motor challenges across autism and DCD; however, relatively little work has integrated caregiver perceptions, standardized motor assessment, and mechanistic postural control measures within the same investigation. Therefore, the purpose of this dissertation was to examine motor competence and postural control in autistic children, children with DCD, and neurotypical …

Drone Dichotomy: Investigating The Application Of Unmanned Aerial Systems For Offensive And Defensive Chemical, Biological, Radiological, And Nuclear-Related Tasks, Evan Jacob Martinovitch

Graduate Theses/Dissertations

This thesis investigates the application of unmanned aerial systems (UAS) for both offensive and defensive chemical, biological, radiological, and nuclear (CBRN) tasks to determine if they serve as a force multiplier on the modern battlefield. As CBRN weapons reemerge as realistic threats alongside the rapid proliferation of UAS, the intersection of these fields presents unique challenges and opportunities. Through a methodology that examines the history of the UAS-CBRN intersection, military doctrine, and the status of UAS technology, this research evaluates the capability of current and emerging UAS against specific CBRN delivery, reconnaissance and surveillance, and decontamination tasks. The analysis conducted …

Small Mammal Communities Within And Land Coverage Around Southwestern Missouri Prairies, Kaitlyn J. Bebensee

Graduate Theses/Dissertations

Land alterations can reduce the amount of suitable habitat necessary for persistence of an associated species. Within such constrained habitats, limited resources may elicit competition, which could cause shifts in abundance and occurrence of species. Missouri prairies have been declining in size, making it imperative to collect reference data on mammal populations within and land use types around remnants. For this study, I trapped small mammals in Southwestern Missouri prairies because they can be indicators of environmental health and can vary in abundance between prairies. I focus on the diet of two dominant small mammals, Peromyscus maniculatus and Microtus ochrogaster …

Gene Editing And The Accessibility Of Bioterrorism: Rethinking Global Biosecurity In The Post-Covid-19 Era, Nicholas Morales

Graduate Theses/Dissertations

COVID‑19 demonstrated how a single biological event can strain health systems, disrupt supply chains, undermine national security, and erode public trust. This shock occurred as biotechnology became dramatically more accessible: gene editing and synthetic biology tools once limited to specialized laboratories are now widely available through inexpensive equipment, open‑source data, and decentralized expertise.

This expanded access accelerates innovation but also broadens the threat landscape. The ability to reconstruct pathogens using publicly available sequences and mail‑order DNA shows that complex biological synthesis is no longer confined to state programs. These risks are amplified by opaque biotechnology activities in China, Russia, and …

Species occupancy, which relates the probability of presence of a species at a specific place and time, is an important component of conservation and wildlife management. Principally it is used for estimation of a species’ distribution as well as understanding species interactions and quantifying environmental effects. The purpose of this study was to analyze occupancy of the Eastern Fox Squirrel (Sciurus niger) across multiple seasons (2019–2022) at Bull Shoals Field Station (BSFS), and to identify potential covariates associated with detection and colonization. Data were drawn from camera trap surveys from 26 sites during summer and fall seasons. Multi-season occupancy models …

Hiding In Plain Sight, Gayle M. Perreault

Antioch University Dissertations & Theses

Some autistic individuals reach adulthood without receiving a diagnosis, and the processes contributing to delayed recognition are not yet fully understood. This study explored how contextual conditions across development related to the emergence and use of camouflaging behaviors in late-diagnosed autistic adults from groups historically underrepresented in autism research. Using an inductive collective case study design, narrative interviews were conducted with seven autistic adults diagnosed after age 15. The analysis examined how participants described learning, maintaining, and interpreting camouflaging behaviors across childhood through early adulthood within social, environmental, and institutional contexts, with attention to how participants experienced environmental expectations and …

Psychology Doctoral Specialization Projects

This doctoral specialty project titled Turning 'Meh' into 'Yeah!': Modifying Motivational Interviewing for the Collegiate Experience explores the adaptation of Motivational Interviewing (MI) to better engage college students in mental health services. Traditional MI is highly effective in resolving ambivalence and fostering behavior change, yet its structure does not always align with the brief, solution-focused counseling models used in university settings. This project examines how MI can be tailored for time-limited interventions while enhancing student autonomy, self-efficacy, and retention in care. It integrates core MI principles—including empathy, ambivalence resolution, and self-efficacy—with developmental psychology and neurobiological research. The final product is …

The Underdiagnosis Of Neurodevelopmental Disorders In Women: Recognizing A Spectrum Of Symptoms, Taylor D. Bloomhuff

Psychology Doctoral Specialization Projects

Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) have long been viewed as predominantly male diagnoses. Based on foundational studies for these disorders, not only are they more prevalent in male children, but symptom severity is also higher in male children. In attention-deficit/hyperactivity disorder in particular, it has become a common assumption that hyperactive/impulsive and combined types are ‘male’ ADHD presentations, while the inattentive type corresponds to the few female children who meet diagnostic criteria. However, emerging research looking at the decrease in autism spectrum disorder and attention-deficit/hyperactivity disorder prevalence rates between gender in adulthood suggests that these neurodevelopmental disorders …

Cultural Roots Of Eating: A Comparative Analysis Of Organic Discourse And Marketing Practices In China And The United States, Zubin (Jane) Guo

Honors Theses

This thesis examines how cultural frameworks influence the development of the organic food market and shape individual attitudes towards the label “organic” in the U.S. and China. While the popularity of organic food has increased in recent years, cognitive and behavioral reactions toward the label “organic” have differed across societies. In the U.S., healthy eating discourse aligns closely with the individualistic culture and atomistic cognitive style, highlighting the importance of salient elements such as specific nutrients or chemical use. In contrast, Chinese healthy eating discourse is based on balance and harmony, which is directly related to traditional Chinese culture of …

N-Allylation Of Secondary Amides With Unsymmetrical Propionates, Remi Graff

Honors Theses

The combination of trimethylsilyl trifluoromethanesulfonate (TMSOTf) and Et3N promotes the N-allylation of 4-methoxyacetanilide 2 with unsymmetrical propionates 1 (eq 1). The amide substrate is believed to undergo conversion to a nucleophilic silyl imidate in the presence of TMSOTf and the amine base, which concurrently promotes carbocation formation in the same flask through the loss of trimethylsilyl propionate, leading to N-allylation of the amide. A range of unsymmetrical propionates, accessed by varying the R and R’ substituents, react efficiently in this one-pot process with yields ranging from 44% to 99%, affording regioselective ratios of up to >20:1 through formation of regioisomers …

Exploring Phosphoregulation Of Myo3a Using Quantitative Fluorescence Image Analysis In Cos7 Cells, Vu Hao Minh Nguyen Phan

Honors Theses

Myosin 3A (MYO3A) is an unconventional myosin involved in the formation and maintenance of hair-cell stereocilia of the sensory epithelia in the inner ear. The kinase domain has been implicated in phosphoregulation of MYO3A activity through intermolecular autophosphorylation. Previous studies using mass spectrometry identified two potential phosphorylation sites in the motor domain. To investigate the regulatory roles of these sites, we generated glutamic acid point mutations in our mchr-MYO3AΔK construct to mimic phosphorylation and assayed the constructs for their ability to tip-localize and influence filopodial density via transfection into COS7 cells. The phosphomimic constructs were less able to generate filopodia …

Maladaptive Shame Coping: The Effects Of Parental Emotion Socialization And Mentalization In The Context Of Maltreatment, Ayelet Raya Malinsky

Selected Full-Text Dissertations 2020-

Among the self-conscious emotions—such as guilt, shame, and embarrassment—shame has increasingly received attention in the clinical literature for its established link to a range of psychopathological outcomes (Paulo et al., 2020). It is a prominent experience for individuals with histories of childhood maltreatment (Herman, 2012) and plays a central role in the development and maintenance of symptoms related to trauma and personality disorders (Lee et al., 2001). Further, maladaptive coping strategies used to manage shame often exacerbate psychological distress (Martin et al., 2021), highlighting a need to identify factors that contribute to the development of chronic shame and related coping …

Field-Scale Evaluation Of Satellite- Derived Vegetation Indices And Image Timing For In-Season Nitrogen Management In Corn, Ana Morales-Ona, Katsutoshi Mizuta, James J. Camberato, Robert Nielsen, Yuxin Miao, Davide Cammarano, German Mandrini, Daniel Quinn

Plant and Soil Sciences Faculty Publications

Introduction: Traditional methods to determine the agronomic optimum nitrogen rate (AONR) for corn (Zea mays L.) rely on grain yield data, limiting in-season decision-making for nitrogen (N) management. Vegetation indices (VIs) derived from satellite imagery can serve as proxies for grain yield and help estimate in-season AONR, enabling timely sidedress applications. This study aimed to (1) quantify how VI–yield relationships vary during the vegetative period across fields with different tillage systems and crop residue; (2) determine whether VI–N response curves can be used to estimate AONR (AONRvi); and (3) assess the accuracy of AONRvi relative to yield-based AONR (AONRy). …
