Salinity Adaption And Toxicity Of Harmful Algal Blooms In Three Bays Of Great Salt Lake (Usa), W. A. Wurtsbaugh, Malin Olofsson, Gregory L. Boyer, Amy Marcarelli
Michigan Tech Publications
Cyanobacterial blooms can be harmful to animals and humans exposed to their toxins; however, their environmental drivers and boundaries still need to be elucidated. Salinity has been demonstrated to be an important driver of community composition that sets boundaries of species migration and survival. The filamentous cyanobacteria Nodularia spumigena forms dense blooms in estuaries around the world, produces the hepatotoxin nodularin, and has been thought to not survive or fix nitrogen (N) in high salinities. From 2005–2009 we studied three bays of Great Salt Lake (USA), two of which are estuaries with salinities ranging from 0 to >90 g L …

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Despite its reputation as one of the least digitized sectors, the construction industry increasingly adopts artificial intelligence (AI) and construction technologies. However, previous research has not adequately explored the benefits of AI techniques and construction technologies nor the correlations between them. This study aims to fill this knowledge gap. To this end, the authors used a multistep research methodology. First, a systematic literature review of studies published between 1985 and 2022 was conducted to identify AI techniques and construction technologies. Second, content and frequency analysis were performed to determine the benefits associated with AI and technology adoption. Finally, a survey …
Executive Compensation In A New Era: Pouring Old Wine Into New Bottles?, Florence Shu-Blankson
Executive Compensation In A New Era: Pouring Old Wine Into New Bottles?, Florence Shu-Blankson
University of Dayton Law Review
The Author’s interest in executive compensation was sparked by the Delaware Court of Chancery’s decision to rescind the largest executive compensation package in U.S. history, awarded to Elon Musk by Tesla.1 Executive compensation has long been a contentious issue, and despite ongoing debates, efforts to regulate it effectively remain elusive. The process by which executive compensation committees and boards of directors determine these awards—along with their independence, the influence of controlling or dominant stockholders, and the transparency of decision-making— raises important questions about whether meaningful change is occurring or if the system remains fundamentally the same, merely repackaged as “old …

Effect Of Digital Noise Reduction Processing On Subcortical Speech Encoding And Relationship To Behavioral Outcomes, Subong Kim, Mary Schroeder, Hari M. Bharadwaj
Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works
Perceptual benefits from digital noise reduction (NR) vary among individuals with different noise tolerance and sensitivity to distortions introduced in NR-processed speech; however, the physiological bases of the variance are understudied. Here, we developed objective measures of speech encoding in the ascending pathway as candidate measures of individual noise tolerance and sensitivity to NR-processed speech using the brainstem responses to speech syllable /da/. The speech-evoked brainstem response was found to be sensitive to the addition of noise and NR processing. The NR effects on the consonant and vowel portion of the responses were robustly quantified using response-to-response correlation metrics and …

Essays On The Economics Of Farmland Valuation And Investment In U.S. Agriculture, Colson Tester
Essays On The Economics Of Farmland Valuation And Investment In U.S. Agriculture, Colson Tester
Graduate Theses and Dissertations
This dissertation presents three empirical essays that collectively advance the understanding of farmland valuation in key U.S. agricultural regions, emphasizing the critical advantages of comprehensive, transaction-based data over traditional survey methods. Farmland represents a significant portion of agricultural wealth, and its accurate valuation is crucial for farmers, investors, and policymakers, influencing everything from credit access to investment strategies. Historically, research has often relied on subjective survey data, which can suffer from biases, inaccuracies, and insufficient granularity. This dissertation addresses these limitations by leveraging extensive datasets of arm’s-length farmland transactions, offering a more precise and market-driven perspective on land values. The …

Computational Fluid Dynamics Based Optimization Method Applied To Hydrokinetic Turbine Devices, Stuart Glenn Fletcher
Graduate Theses and Dissertations
This thesis presents a computational investigation of optimal kinematic operating parameters governing various hydrokinetic turbines (HKT) systems for the use of power generation within river and tidal environments. Two separate studies are performed. The first study investigates optimal cycle parameters for simple and complex kinematic modes governing the motion of oscillating foil energy harvesters (OFEH). An iterative gradient-ascent optimization method is used to search for local efficiency optima based on an initial set of kinematic parameters. To search the operational space for up to eight degrees of freedom (DOF), a maximin space filling condition was implemented to efficiently compute initial …
Validation Studies Of A Dynamic Hybrid Rans-Les Turbulence Modeling Strategy For Cfd Simulation Of Gas Turbine Component Film Cooling, Cole Simmonds
Validation Studies Of A Dynamic Hybrid Rans-Les Turbulence Modeling Strategy For Cfd Simulation Of Gas Turbine Component Film Cooling, Cole Simmonds
Graduate Theses and Dissertations
Computational prediction of the flow physics associated with gas turbine film cooling is important for ensuring effective heat transfer design. These flow fields are highly turbulent and anisotropic, making the accuracy and efficiency of the chosen turbulence model an important aspect of performing high quality computational fluid dynamics (CFD) based analysis. Current industry standard Reynolds-averaged Navier-Stokes (RANS) turbulence models such as RANS k-ω SST, while computationally efficient, are subject to relatively high levels of uncertainty in their ability to predict these turbulent flow fields. In contrast, high fidelity methods such as Large Eddy Simulation (LES) are computationally very expensive, while …

Is Artificial Intelligence Really Taking Our Jobs?, Francesca A. Strom
Is Artificial Intelligence Really Taking Our Jobs?, Francesca A. Strom
Undergraduate Theses and Capstone Projects
This paper studies how artificial intelligence has reshaped occupational opportunities in the United States by analyzing changes in employment, median wages, and wage inequality across all occupations from 2014 through 2024. Using a difference-in-differences framework, I compare occupations associated with AI-related tasks to those not directly exposed to generative AI, with particular attention to the structural break introduced by the mainstream release of generative AI tools in 2022. The results show no statistically significant decline in employment among AI-exposed occupations, indicating that early adoption did not lead to measurable job displacement. Instead, the strongest effects appear in wage inequality. Among …

Optimal Control Of Human Exercise Using An Individualized Physiological Three-Tank Model And Dynamic Programming, Asal Lotfi
All Theses
This thesis develops a physiologically inspired three-tank model of human bioenergetics to describe and optimize fatigue and recovery during exercise. The aerobic, phosphagen, and glycogen systems are modeled as coupled reservoirs whose states constrain instantaneous power output. Building on this representation, dynamic programming is used to compute pacing strategies that respect physiological limits while maximizing task-specific goals such as peak power or total work over a fixed duration, enabling individualized, goal-driven exercise prescriptions. The three-tank dynamics are formulated in continuous time and then discretized under a zero-order-hold assumption for simulation and optimal control. Model parameters are linked to standard field …

Two Uncited Latin Resources In King Robert Of Naples’ Sermon On Friendship For The Lombard League, Chris Nighman
Two Uncited Latin Resources In King Robert Of Naples’ Sermon On Friendship For The Lombard League, Chris Nighman
History Faculty Publications
This article demonstrates the reception of Thomas of Ireland’s Manipulus florum (1306) and John of Wales’ Communiloquium (ca. 1270) in a sermon by King Robert of Naples (1276-1343) promoting the revival of the military alliance known as the Lombard League, and also his use of the Manipulus in another sermon. A full edition of Robert’s sermon “pro liga Lombardie” is appended. It also corrects the misattribution to Robert of a collection of anecdotes and quotations attributed to ancient philosophers and provides a brief comparative analysis of the short and long recensions of the Communiloquium.
“Starlight Suite”: A Compositional Exploration Of The Argo Navis Constellations In Three Movements, Adam Miller
“Starlight Suite”: A Compositional Exploration Of The Argo Navis Constellations In Three Movements, Adam Miller
Student Publications
This thesis explores a compositional technique in which stellar constellations are arranged upon musical staves in a variety of iterations to create a basis from which to draw melodic, harmonic, and rhythmic material. These raw extrapolations of unaltered notes are then arranged and orchestrated into thematic music for full orchestra, centered around elements from the mythological background behind the constellations used. An accompanying analysis explains the specific applications of this technique within each movement of the work, the significance of each, and the variety of ways in which musical inspiration was drawn from the raw materials. The objective of this …

From Concept To Community: Building And Sustaining Communication Research Labs, America L. Edwards, Matthew J. A. Craig, Hannah E. Jones, Chad Edwards, Autumn P. Edwards
Journal of the Association for Communication Administration
This essay explores the conceptual, practical, and relational foundations of building and sustaining communication research labs. Drawing on early models of research teams, we argue that contemporary labs function as living systems that integrate research, teaching, mentorship, and community engagement. The essay outlines practical considerations for creating and maintaining labs, including recruitment, infrastructure, leadership succession, and digital presence, while emphasizing the importance of flexibility and autonomy. Rather than viewing labs as static organizational units, we position them as relational ecosystems that evolve through connection, shared purpose, and adaptability across time and institutions. Ultimately, this work encourages scholars to view lab-building …

Making The Invisible Visible: Cultivating Contexts For Equitable Workloads, Andrea Carlile
Journal of the Association for Communication Administration
Women make up the majority of degree earners and most of those teaching at higher education institutions. Yet, women are not advancing to the highest ranks. How female faculty receive credit for their work may account for the discrepancy in women advancing to the highest ranks. This single-institution case study explored institutional practices and policies as they related to workload satisfaction and rewards for female faculty. Following the framework from the Faculty Workload and Rewards Project, FWRP, the case used the constructs of equity-minded faculty workloads to shape the analysis. Three themes emerged in the analysis: context matters, transparency practices, …

Integrating Evidence Synthesis Into Doctoral Research: A Guide For Family Medicine And Primary Care, Klaus B. Von Pressentin, Jacob Shabani, Taryn Young
Integrating Evidence Synthesis Into Doctoral Research: A Guide For Family Medicine And Primary Care, Klaus B. Von Pressentin, Jacob Shabani, Taryn Young
Family Medicine, East Africa
Given the increased complexity of healthcare needs, evidence-informed practices are needed, now more than ever. Combining the best available research evidence, the perspectives of patients and communities, and the voices of healthcare workers in guiding policy and practice is essential. All of us involved in providing and strengthening family medicine and primary care need to be good consumers (users) of research, and some will be good producers (doers) of research. In both using and doing research, a helpful starting point is evidence synthesis – a form of secondary research that collates primary research on the same research question. This short …
Dielectric Properties Of Surface-Doped Partially Stabilised Zirconia With Ceramic Nanomaterials, Lara Al-Hakeem, Shihab Zaidan, Wafaa Khalef
Dielectric Properties Of Surface-Doped Partially Stabilised Zirconia With Ceramic Nanomaterials, Lara Al-Hakeem, Shihab Zaidan, Wafaa Khalef
Journal of Applied Sciences and Nanotechnology
The microstructural and dielectric properties of Yttria-partially stabilized zirconia (Y-PSZ) were studied before and after sintering with BaTiO3 and WO3 doping. After sintering, FE-SEM analysis revealed increased grain coalescence and growth, with BaTiO3 causing 300 nm grain expansion and WO3 promoting uniform grain distribution without significant grain size increase (~200 nm). These microstructural changes dramatically altered dielectric behavior. All sintered samples had higher dielectric constants than pre-sintered ones between 100–1000 kHz due to reduced porosity and enhanced homogeneity. Dielectric constant was highest in BaTiO3-doped Y-PSZ at lower frequencies, while WO-doped showed superior frequency stability and lower dielectric loss across the …
Impacts Of Nutrient Addition And Disturbance On Coastal Dune Arthropod Communities And Trophic Interactions, Kayla Beitzel
Impacts Of Nutrient Addition And Disturbance On Coastal Dune Arthropod Communities And Trophic Interactions, Kayla Beitzel
Graduate Theses and Dissertations (2019 - present)
Coastal dune ecosystems face ongoing threats from human-mediated disturbance and altered resource availability. Because these dunes provide critical habitat for many organisms, including shorebirds, beach mice, and arthropods, changes in disturbance regimes or resource availability can impact plant communities and higher trophic levels by altering plant richness and productivity, which in turn influence arthropod abundance and diversity. To examine how disturbance and nutrient addition affect arthropod communities, we established twenty 5×5 m plots on Dauphin Island, crossing mechanical disturbance with a 10 g m⁻² addition of nitrogen, phosphorus, and potassium, replicated across five experimental blocks. Arthropods were sampled using three …
Climate Science And Natural Resource Litigation, Jessica A. Wentz
Climate Science And Natural Resource Litigation, Jessica A. Wentz
Sabin Center for Climate Change Law
Climate change has major implications for sustainable use and conservation of natural resources. Many natural systems are already under severe stress and may be unable to sustain historical use patterns; resource management decisions can also exacerbate or mitigate climate change by affecting the balance of greenhouse gases in the atmosphere. This Article describes the legal and scientific basis for recognizing agencies’ obligations to assess and respond to climate change, drawing insights from a survey of U.S. litigation involving forests, fisheries, rangelands, and freshwater resources. The cases suggest litigants have been somewhat successful in driving more rigorous assessments of climate change. …
The Disaster Management Complex: Law’S Adaptations In Times Of Climate Disaster, Michael Burger, Jeffrey Schlegelmilch, Lucia Bragg
The Disaster Management Complex: Law’S Adaptations In Times Of Climate Disaster, Michael Burger, Jeffrey Schlegelmilch, Lucia Bragg
Sabin Center for Climate Change Law
The Anthropocene is marked by constant climate-related disasters and defined by the urgent need to foster and implement adaptations to future climate impacts that reduce disaster risk. The intensity, frequency, and severity of extreme weather events continue to rise even as nations and corporations alike miss their emissions targets, all promising a hotter, wetter, and more extreme future. A number of federal agencies, including the Federal Emergency Management Agency (FEMA), have, at times, sought to adapt their own famously fragmented responses to these changing circumstances. However, federal disaster response is conducted against a backdrop of authorizing legislation that is designed …

School of Medicine Publications
Background: Tuberculosis (TB) remains a leading cause of morbidity and mortality worldwide. Individuals with type 2 diabetes (T2D) are at increased risk of developing active TB, tend to present with more severe disease and experience adverse treatment outcomes compared to individuals without T2D co-morbidity. However, the underlying mechanisms responsible for increased susceptibility of patients with T2D to TB remain poorly understood.
Methods: We performed bronchoscopies and collected bronchoalveolar lavage fluid (BAL) from TB contacts with and without T2D in South Africa and obtained paired human alveolar macrophages (HAMs) and monocyte-derived macrophages (MDMs) for transcriptomic, epigenetic and functional assays.
Findings: Following …
