Largemouth Bass Diet Changes Through The Summer In Central Minnesota, Ethan Kunz

Journal of Earth and Life Science

Largemouth Bass Micropterus nigricans is one of the most widespread fish species in the world, due in part to human introduction for angling. Largemouth Bass are opportunistic predators that will consume the largest prey they can often find; however, it has been shown that their diet mainly consists of invertebrates such as crayfish, with less focus on other fish species. This research aimed to determine what the Largemouth Bass diets in Central Minnesota consist of, and how they may change from the beginning of summer through the beginning of fall. A total of 174 Largemouth Bass were sampled from late …

Relationship Between Ratio Of Hybrid Sunfish To Their Parent Species And Latitude, Maxwell Kattner

Journal of Earth and Life Science

Hybrid sunfish of the Lepomis genus make up a generally small but notable portion of the population of sunfish in Minnesota lakes. Hybrid sunfish play a significant role in freshwater ecosystems across the United States. They are both morphologically and behaviorally distinct in some ways and similar in other ways to their parent species, causing them to both fill and compete with their parent species for niches occupied by multiple Lepomis species. Despite this, the ratio of hybrid sunfish to their parent species has never been properly explored. This study observed if the ratio of hybrid sunfish to their parent …

Redness As Fact And Sensibility In Mindanao’S Abaca Ikat Cloth, Cherubim Quizon

Department of Sociology, Anthropology and Social Work Publications

This paper proposes an approach to the color red as a central consideration in cloth making in the southern Philippines where thread is made from abaca (Musa textilis), a historically and economically significant plant in the banana family. It focuses on red dye derived from the root of the Morinda plant (Morinda citrifolia) and how it is utilized and theorized, both pragmatically and metaphorically, by indigenous women of Mindanao. Drawing on research that relies on ethnographic fieldwork and informed by early 20th century American museum collecting during a time of pacification, this paper frames a phenomenological query using mixed methods …

Citizen Engagement In Budget Simulation: Examining The Effectiveness Of Balancing Act Modules In Aligning Public Priorities And Allocation Choices, Frankline Muthomi

Public Administration Faculty Publications and Presentations

This study investigates the extent to which individuals exhibit consistency in their preferences during sequential budget simulation exercises, as well as the factors that shape these preferences. Grounded in behavioral and citizen participation frameworks, the analysis demonstrates that the simultaneous use of priority-setting and budget-balancing modules encourages participants to allocate resources in ways that reflect their previously articulated priorities. While instances of inconsistency remain common, preference consistency is associated with participants’ sustained support for their favored programs, their commitment to ensuring adequate resource allocation, and, to some extent, their willingness to finance these programs. The findings suggest that the integrated …

Patient-Identified Reasons For Premature Termination: A Systematic Review, Jack N. Mizrahi M.S.

Selected Full Text Dissertations, 2011-

Premature unilateral termination has been estimated to occur in approximately 20% of patients seeking psychotherapy. Research has identified a variety of factors including patient, therapist and treatment variables that may contribute to psychotherapy dropout. There is currently quite limited research on patients’ perspective of premature termination, with much of our understanding based on therapist’s perspective. Although therapist perspectives are an important source of information regarding premature termination, therapist judgments about patient progress are often inaccurate, and therapists consistently struggle with foreseeing unilateral termination. In addition, therapists have been found to attribute premature termination more to patient factors than their own …

Prodigal Daughters: The Crisis Facing Generation Z Women, Kristin Brouwer

Doctor of Ministry

Why are Generation Z women (born approximately between 1997 and 2012), increasingly leaving organized Christian religion in the United States? This question became personal in my office at a Christian liberal arts college, where national statistics took on the faces and stories of students I teach and mentor. For the first time in American history, young men are now more religious than young women, and nearly four in ten Gen Z women identify as religiously unaffiliated. Yet their departure is not primarily a rejection of God; it is a rejection of distorted representations of God, faith, and church.

Drawing on …

The Importance Of Mental Health Education In The Black Church: Exploring Mental Health And Trauma Through A Biblical Lens, Navita Kj Johnson-Belcher

Doctor of Ministry

The Black church has historically served as a cornerstone for African American spiritual and communal life yet faces significant challenges in addressing mental health needs rooted in generational trauma and systemic oppression. This dissertation explores the crisis of silence surrounding mental health in Black church contexts, where stigma, pastoral limitations, and historical mistrust of institutional systems create barriers to healing. Through examination of biblical perspectives on suffering, church-based mental health programs, and emerging digital ministry models, this study demonstrates that online platforms can effectively integrate trauma-informed care with theological education.

The research presents a digital, trauma-informed, biblically-based, mental health education …

Significant Women: From Spiritual Narratives To Modern Advocacy, Mary Melissa Henderson

Doctor of Ministry

Significant Women addresses the need for congregational advocates who support and empower women in ministry. This advocacy is rooted in a renewed perspective on women’s roles within both Scripture and the modern church.

Research reveals that tradition, rather than theology, is the primary catalyst for gender limitations in the Church—often driven by a fear of disrupting established operations. Another key insight is that Jesus acts as the "antithesis of patriarchy," intentionally elevating and empowering women to carry the Gospel. While academic resources are plentiful, a significant "white space" exists for non-academic resources designed for laypeople and everyday churchgoers. Stakeholders most …

This body of work explores the various benefits of implementing a bereavement support ministry in a resource-constrained church in Chicago, Illinois. The research will outline how a bereavement ministry can offer emotional support, spiritual guidance, and provide educational resources, community building, outline a budget proposal, and a grant opportunities, partnership with local agencies, training for volunteers, and practical help to bereaved members in a church, as well as the bereaved community.

Bereavement is an inevitable part of the human experience, and churches have historically served as …

Synergistic Effects Of Salinization And Artificial Root Exudates On Soil Phosphatase Activity In Coastal Soil, Nicolina Lentine, Sarah E. Krisak, Dirk W. Vanderklein, Matthew S. Schuler, Nina M. Goodey

Department of Biology Faculty Scholarship and Creative Works

Coastal soil salinization from rising seawater levels has adverse impacts on soil function, seed germination, and plant growth. Root exudates play a key role in supporting microbial activity, nutrient cycling, and plant health, yet little is known about the combined effects of salinization and the addition of artificial root exudates (AREs) on soils. We investigated the impacts of sodium chloride (NaCl) and AREs, alone and in combination, on soil microbial function and the growth and survival of Chamaecyparis thyoides saplings. In a three-by-three fully factorial matrix, the combined NaCl and AREs treatment increased soil phosphatase activity more than the additive …

Captive Model Test For Hydrodynamic Derivatives Of Ship Maneuvering In Regular Head Waves, Pin-Yuan Huang, Zih-Yao Lin, Tsung-Yueh Lin, Fu-En Lee, Yan-Wei Lai

Journal of Marine Science and Technology–Taiwan

The motion of ship in wave can be discussed in seakeeping and maneuvering. In model tests, the former is found by the motion response of waves while the latter requires captive model test to acquire hydrodynamic derivatives. The hydrodynamic derivatives in waves are discovered to be different from those in calm water. To understand better the behavior of maneuverability in waves, maneuvering tests in a wide range of waves are performed in this study. This study presents an experimental investigation into the maneuvering behavior of a container ship in regular waves, covering a wide range of wavelengths from half to …

Mitigating Data Privacy Risks In Political Micro-Targeting Through Gdpr-Compliant Federated Learning: Lessons From The Cambridge Analytica Controversy, Jingfan (Serena) Xiao

Marquette Intellectual Property & Innovation Law Review

Political micro-targeting employs granular data analytics to deliver hyper- personalized political messaging, raising fundamental tensions between electoral strategy, data privacy, and democratic accountability. The Facebook- Cambridge Analytica scandal exposed significant gaps in pre-GDPR data protection laws, highlighting the risks of unchecked algorithmic profiling in shaping voter behavior. However, as micro-targeting evolves under more sophisticated AI-driven systems, a pressing question emerges: should AI- generated political messaging qualify for First Amendment protection? This Article introduces the concept of speech certainty, arguing that speech must be intentional and cognitively understood by the speaker at the moment of articulation to warrant constitutional protection. Under …

Optimizing Efficiency In Joint Injections In An Outpatient Orthopedic Oncology Clinic Using Lean Six Sigma, William Alexander Byrd

Doctor of Nursing Practice (DNP) Scholarly Projects - Archive

Prolonged in-room wait time in an outpatient orthopedic oncology clinic was identified as an important driver of dissatisfaction and operational inefficiency. Baseline in-room times in this setting were reported as M=96.2 minutes for patients receiving injections and M=92.9 minutes for those not receiving injections. This quality improvement project used Lean Six Sigma (LSS) DMAIC (Define, Measure, Analyze, Improve, Control) framework to streamline clinic workflow for the joint injection process. Over an eight-week period, four key interventions were introduced: a standardized order set for medications, pre-bundled supplies and portable supply toolbox, telephone pre-consenting of patients, and optimized scheduling of …

Histopathology And Applications Of Event-Based Cameras, Jace Sung, Kelly Lao, Quinton Qu, Adithya Pediredla

Wetterhahn Science Symposium Posters

Capturing and analyzing visual phenomena at their natural time scale is critical in both science and engineering. For instance, in industrial manufacturing, high-speed capture of defects and crack propagation ensures quality control. In sports, capturing high-impact collisions in football or rugby helps in better understanding injury mechanisms and developing more effective prevention strategies. In autonomous robotics, drones, and cars, high-speed cameras enable split-second decisions, even during fast maneuvers. However, high-speed cameras are expensive, costing upwards of $100,000, and are bulky, limiting their widespread adoption. Recently, event cameras have emerged as an affordable, small-form-factor alternative, but they only capture binary temporal …

Exploring Mesoproterozoic Marine Redox States In A Young Banded Iron Formation From The Needle Mountains, Jaya Sharma, Brenhin Keller

Wetterhahn Science Symposium Posters

Banded iron formations (BIF), as redox-dependent chemical sedimentary rocks, have served as proxies for marine and atmospheric oxygen and iron conditions throughout Earth history. While abundant in the Archean and early Proterozoic, the widespread deposition of BIFs declined following the Great Oxidation Event, as oxygenated surface waters prevented the accumulation of ferrous iron. However, the Needle Mountains, located in southwestern Colorado, houses an anomalously young BIFs deposited between 1.786±10 - 1.801±6 Ga given existing geochronology. Here, we use rare earth element (REE) systematics, bulk chemistry, and petrographic analysis to determine the depositional conditions under which this BIF was formed. We …

Probing Feni Alloys With Atomic Precision, Scipio Han, Kaushik Rajkumar Jayaprabha, Xin Qi

Wetterhahn Science Symposium Posters

We compared EAM and MEAM atomic potentials for modeling FeNi (tetrataenite), a rare 50/50 alloy found in meteorites. Picking 4 potentials, we calculated minimum lattice constants and order-disorder transition temperatures. MEAM potentials accurately predicted the experimental transition temperature, confirming that MEAM better captures FeNi's directional bonding.

Risky Decision-Making Under Uncertainty, Suyoung Yoo, Jae Hyung Woo

Wetterhahn Science Symposium Posters

This research project aims to discover how a person’s brain continuously learns about its changing environment and how those memories dynamically alter their subsequent willingness to take risks. By testing 73 participants on a two-stage computer module, the study evaluates whether humans evaluate risk absolutely or relatively to their historical surroundings. In Stage 1, participants use reinforcement learning to track a hidden, shifting "lucky room" context. In contrast, in Stage 2, they face explicit two-option gamble cards in which they must weigh different point amounts and win percentages. Computational maximum likelihood estimation proved that a Subjective Utility (SU) model, which …

Measuring The Impact Of 3d Printers On The Health Of Youth, Alexis Kostin, Olla Obeid, Oz Trost

Wetterhahn Science Symposium Posters

3D printers are used more widely than ever before; they can be found in factories, hospitals, and even schools. However, the health effects of the VOCs and UFPs that these machines emit have yet to be fully understood. In collaboration with the University of Nevada, Las Vegas, this study utilizes an Air Gradient One sensor at the Diamond Lab to monitor VOC and UFP emissions before, during, and after 3D printing sessions. By comparing these levels to EPA and CDC safety standards, we aim to quantify the respiratory risks posed to youth.

Carbon Storage In Headwaters Can Respond Rapidly To Climate Change, Maddie Benello, Carl Renshaw, Joshua Landis

Wetterhahn Science Symposium Posters

Headwater streams play a critical role in the global carbon cycle, serving as significant sites of carbon storage. While there have been recent efforts to quantify carbon storage in headwater streams in the western United States, there remains limited understanding of both the volume and timescale of carbon storage in northeastern forests which often have extensive logging and agricultural histories. Here, we quantify the carbon stock, residence time, and flux of a zero-to-first order headwater stream in Charles Downer State Forest (DF), VT using novel fallout radionuclide (FRN) chronometry. We find DF headwaters have a carbon stock of 66.2 Mg …

Cell Surface Expansion And Tension Regulation: How Cellular Forces Shape Embryonic Development, Samantha A. Pressman, Sophia M. Micale, Bing He

Wetterhahn Science Symposium Posters

Congenital birth deformities often arise during epithelial morphogenesis, displaying the need to understand the mechanisms underlying this process. Cell shape changes that mediate morphogenesis often require cell surface expansion to accommodate shifts in 3D tissue geometry. Our lab has identified Four Wheel Drive (Fwd), a Golgi-localized phosphatidylinositol 4-kinase (PI4K) IIIβ ortholog, as a regulator for cell surface expansion during Drosophila ventral furrow formation, a well-characterized model for epithelial folding. We hypothesize that Fwd and Rab11, a regulator of exocytosis and endocytic recycling, coordinate the trans-Golgi network and recycling endosomes to promote vesicle trafficking. Using live imaging of fluorescently tagged Fwd …

Magnetic Anisotropy Engineering In Rare-Earth-Free Iron-Based Magnetic Materials, Pramanand Joshi

Physics Dissertations - Archive

The development of high-performance, rare-earth-free hard magnetic materials is critical for next-generation energy, information, and spin-based technologies. This dissertation investigates structure-property relationships in iron-based magnetic systems, including iron carbides, Fe-Co-B boride alloys, hexaferrites, and FeCo nanostructures, synthesized via chemical and metallurgical routes. Through controlled synthesis and comprehensive structural and magnetic characterization, this work demonstrates that magnetic anisotropy, coercivity, and thermal stability can be systematically controlled through morphology design, compositional tuning, microstructural refinement, and interparticle interaction modulation.

Morphology-driven enhancement of magnetic properties, particularly coercivity and blocking temperature, is established in phase-pure Fe₅C₂ nanostructures. By precisely controlling particle geometry, …

Applications Of Doppler Broadening Spectroscopy For The Characterization Of The Surface And Near Surface Of Two-Dimensional Heterostructures, Hany M. Mahdy

Physics Dissertations

This dissertation describes experiments and the analysis of Doppler broadening spectroscopy applied to metal surfaces (Cu, Ag, Au), graphene/Cu heterostructures, and SiGe heterostructures, with particular emphasis on the development of new approaches for extracting quantitative information from annihilation spectra.

The first part establishes the capability of Doppler broadening spectroscopy, particularly coincidence Doppler broadening (CDB), as a surface-sensitive technique. Measurements on clean and adsorbate-covered Cu, Ag, and Au surfaces demonstrate that Doppler-broadened annihilation spectra retain element-specific signatures from the topmost atomic layer. New analysis methods based on ratio-curve modeling enable identification and quantification of sub-monolayer adsorbates, including sulfur, oxygen, selenium, and …

Status Anxiety And Public Support For Reactionary Political Movements, Timothy E. Randall

Political Science Theses

In this enquiry, I explore the conditions that make members of the public receptive to the appeals of reactionary political movements. I also explore the means by which reactionary movements leverage those conditions to gain support. I argue that crisis and status threat conditions prime members of the public to be receptive to the appeals of reactionary movements and that the strategic leveraging of these conditions in their narratives gives rise to status anxiety which, in turn, moves members of traditionally dominant groups to support these movements. I develop an explanatory theoretical framework for understanding status anxiety and its role …

Numerical And Machine Learning Based Recreation Of Damage Morphologies Of Barely Visible Impact Damage, Oscar A. Valdez

Mechanical and Aerospace Engineering Dissertations

Composite laminates are highly sought after in the aerospace industry as they provide strength without dramatically increasing the weight of manufactured structures. However, composite laminates are susceptible to barely visible impact damage caused by routine activities. This type of damage can easily go unnoticed while significantly reducing the load-carrying capability of the laminate. Current non-destructive evaluation techniques, such as ultrasonic scanning, can reveal the damage footprint but provide no insight into delamination through-the-thickness due to the shadowing effect. Micro-computed tomography offers ply-by-ply damage resolution but is unsuitable for field inspections and is constrained by specimen size. This study aims to …

Set-Theoretic Reachability-Informed Model Predictive Control For Mechanical And Aerospace Systems, Jinaykumar Nitinkumar Patel

Mechanical and Aerospace Engineering Dissertations

Modern mechanical and aerospace systems increasingly operate autonomously in environments characterized by nonlinear dynamics, uncertainty, and safety constraints. In these settings, estimation and control methods based on nominal models and single-point trajectory predictions are usually insufficient to ensure safe and reliable operation. This dissertation uses a set-theoretic perspective, in which the system state, uncertainty, and admissible behavior are described by sets instead of point estimates. The key question is not only what the state is, but what set of states remains consistent with the dynamics, disturbances, control limits, and available measurements. This provides bounded descriptions of uncertainty and supports control …

Organizational Support And Burnout In Occupational And Physical Therapists: A Quantitative Correlational Study In The Acute Care Setting, Brenda Ballou-Boyd Mrs.

Occupational Therapy Doctorate Capstone Projects

Background: The United States is positioned for an upcoming healthcare crisis with an estimated deficit of 100,000 healthcare professionals by 2028 (Mercer, 2024). Burnout is well documented among the healthcare community and is a major contributing factor to an ongoing shortage of healthcare professionals, including occupational and physical therapists. Most prior research has focused on burnout from a personal level, but addressing burnout from an organizational level may be more effective in reducing this phenomenon among occupational and physical therapy providers.

Purpose: Despite the high levels of burnout reported, a substantial gap exists in research dedicated towards the …
