As outlined in the NCDSR Harvest Strategy (DPIRD, 2017), the Kimberley resource is currently monitored through annual reviews of total removals and catch rate trends of indicator species, as well as periodic (every …

If You Take Care Of Me, I’Ll Take Care Of You: The Mutual Gains Of Parental Support For Employee And Organizational Well-Being, Cara-Lynn Scheuer, Angela R. Grotto, Jessica L. Doll

Department of Management Faculty Scholarship and Creative Works

As the number of working parents rises, employers are increasingly called upon to support employees’ work–family (WF) obligations. Grounded in conservation of resources theory, we examined how providing varying degrees of parental support (paid vs. unpaid leave and family-supportive vs. -unsupportive leadership) is mutually beneficial to employee and organizational well-being – the ultimate criterion for organizational science. Participants (N = 538) were randomly assigned to read vignettes that varied the amount of parental support provided for expectant working parents. We tested whether WF benefits fairness perceptions moderated the indirect effects of parental support on felt obligation through job-related anxiety. Findings …

Evaluating The Effects Of Agricultural Management Practices On Beneficial Arthropod Communities, Isaac Newton Ativor

Doctoral Dissertations

Arthropods provide essential ecosystem services to our agricultural landscapes. These ecosystem services include biological control of pest organisms, including weed seeds, and plant pollination. Concerningly, however, there has been a global decline in insect populations over the last decade, a major cause of which is agricultural intensification. Previous research has demonstrated that agricultural management practices can strongly influence the species composition and abundance of arthropod communities, and therefore presumably the ecosystem services or disservices these organisms provide; however, our understanding of these interactions remains limited. I conducted three studies to investigate whether agricultural practices common in annual row crop (tillage …

Interpolated Factored Green's Function (Ifgf) Method Of Acceleration For Electromagnetic Scattering Off Of A Perfectly Electrically Conducting Surface, Mathew D'Amico

Doctoral Dissertations

Boundary integral equation (BIE) methods are advantageous in scattering problems due to their reduction of the problem's dimensionality as well as their automatic satisfaction of far-field radiation conditions. Specifically, for electromagnetic scattering off of perfectly electrically conducting (PEC) geometries, we are concerned with the magnetic field integral equation (MFIE). Typically, BIE implementation is iterative, with each direct integration requiring $\mathcal{O}(N^2)$ operations for a grid size $N$. For large $N$, this incurs very large computation times. To date, all existing methods that reduce the asymptotic operational complexity of evaluating the MFIE integral to $\mathcal{O}(N\log N)$ rely on use of the Fast …

Reentry, Justice Involvement, And Evolving Perspectives: Moving Toward Rehabilitation?, Casey Cavanaugh

Doctoral Dissertations

As prison populations climb, it is inevitable that the vast majority of incarcerated individuals will eventually return to the community. As they return, they face numerous barriers resulting from their incarceration. While it is important to identify barriers to reentry, it is also important to identify facilitators of reentry, which include forces that may mitigate reentry challenges. A tool is needed to measure this comprehensive list of barriers and facilitators, and in doing so, one may identify improvements and successes that stretch beyond merely that of recidivism. “Successful” reentry is typically measured through low recidivism rates, which recent government reports …

The revised instrument shows improved model fit, reinforcing the importance of refining assessment tools for chemistry education research.The effects of prior knowledge and self-efficacy on student performance in a first-semester general chemistry course are investigated in the second chapter. Self-efficacy, defined as a learner's belief in their capability to successfully accomplish …

Planning Responses To Drinking Water System Emergencies, Jingyan Huang

Doctoral Dissertations

Despite extensive efforts to ensure clean and safe drinking water, drinking water contamination emergencies remain a persistent challenge in the United States. These events can result in widespread public health impacts, economic losses, and long-term environmental damage, particularly when triggered by hazardous chemical releases. Effective management of such crises requires a dual focus on both technical preparedness and human decision-making. This dissertation addresses these challenges through a two-part investigation that bridges pre-incident planning and post-incident response. It is guided by two core research objectives: (1) to evaluate commonly applied emergency countermeasures from both resilience and sustainability perspectives; and (2) to …

Psychological Factors Of Acting Talent And Success: You've Got "It", Lorelei Tierney Himlin

Doctoral Dissertations

The goal of an actor is to become invisible, bringing a character to life so convincingly that the audience forgets the actor exists outside the role. Different schools of acting often describe differing methods of portraying characters to this same general effect. To followers of the Meisner school, for example, “acting is behaving truthfully under imaginary circumstances” (Meisner et al., 1987). The “truthful” part involves creating a comprehensive mental model of a character’s imagined personality in order to fully embody that personality and extrapolate it to a situation. Then the actor uses a variety of acting techniques to think and …

Black Hole-Neutron Star Mergers: Numerical Relativity Studies Of Remnant Matter, Gravitational Waveforms, And Automated Simulation Workflows, Tia Kathleen Martineau

Doctoral Dissertations

Black hole–neutron star (BHNS) mergers are key sources for multimessenger astrophysics, offering insight into strong-field gravity and the behavior of matter at supranuclear densities. This dissertation presents three independent contributions to the study of BHNS systems using the Spectral Einstein Code (SpEC). First, a set of simulations spanning a range of mass ratios, black hole spins, and neutron star equations of state is used to map disruption thresholds and quantify remnant disk masses, unbound ejecta, and ejecta composition. These results are compared to predictions from remnant mass model FNH18, to assess its reliability in accurately predicting the resulting remnant masses …

Multi-Level Characterization And Testing Of Fatigue, Fracture And Creep Of The Ultra-High Strength Low-Alloy Steel Fabricated Via Laser Powder Bed Fusion, Nemanja Kljestan

Doctoral Dissertations

This dissertation presents a comprehensive experimental investigation of the mechanical behavior of an high-strength low-alloy (HSLA) steel fabricated via laser powder bed fusion (LPBF). The work focuses on fatigue strength, laser shock peening (LSP) effects, creep behavior, fatigue crack growth and fracture toughness. Fatigue strength was assessed using rotating bending tests, showing superior performance of LPBF specimens compared to as-cast materials due to the dual-variant martensitic microstructures. Laser shock peening enhanced fatigue life by inducing compressive residual stresses, delaying crack initiation and slowing crack propagation. Creep behavior was evaluated for different layer thicknesses, with thinner layers improving secondary creep resistance …

Simulations Of Perpendicular Electron Holes, James Patrick Mcclung

Doctoral Dissertations

Bernstein–Greene–Kruskal modes commonly manifest as electron holes and electrostatic solitary waves in space plasmas. These Debye-scale structures are nonlinear solutions to the steady-state Vlasov–Poisson system. Solutions in one dimension are highly tractable mathematically, observationally, and computationally, and are relatively well-understood. Higher-dimensional, magnetized plasmas are less amenable to study, however. Following a 20-year history of theoretical developments in two-dimensional BGK modes, this thesis presents the first high-resolution 2D and 3D simulations thereof. Stability conditions and phase-space dynamics are discovered and discussed. The simulated modes are ultimately compared to observed electron holes and modern width-amplitude relations. In addition, a significant portion of …

Missing Child Incidents Resulting In Death: Distinguishing Features Between False Allegations, Wander-Offs, And True Child Abductions, Madison N. Sundberg-Alley

Doctoral Dissertations

Children are reported missing in the United States for a multitude of reasons every year. Often, law enforcement is tasked with investigating these disappearances and recovering the missing child. In some instances, determining the reason why a child is missing can be challenging. This study focuses on three types of missing child episodes that result in fatality: child abduction homicides (CAH), false allegations of child disappearance (FACD), and wander-offs (WO). This exploratory analysis contributes to a gap in the literature by identifying some possible differences between case types that may assist police in determining the likely explanation for the disappearance. …

Analyzing Regions For The Study Of Localized Fluctuations In The Ground Magnetic Field For The Development Of A Global Risk-Assessment Forecast, Michael Kavanagh Coughlan

Doctoral Dissertations

The dynamic relationship between the solar wind and the Earth's magnetic field can produce rapid changes in the geomagnetic field measured on the ground ($dB_H/dt$). The fluctuations can be highly localized, with differences of up to 100s of nT/min in a small geographic area. The field of space weather is entering a more data-driven era, with enormous amounts of publicly available datasets from satellites and ground measurements. In this work modern machine learning techniques were employed to make forecasting risk-assessment predictions of large and localized $dB_H/dt$, and model explainability methods were employed to understand the non-linear connections being made. These …

Computational String Theory Using Machine Learning, Giorgi Butbaia

Doctoral Dissertations

Low-energy couplings of certain superstring theories are related to the masses of the particles. One of the most promising superstring theories is $\mathcal{N}=1$ supersymmetric $E_8\times E_8$ heterotic string theory. In a certain embedding of the standard model into $E_8\times E_8$ gauge group of the heterotic string, the particle spectrum consists of $(\mathbf{27})^3$, $(\overline{\mathbf{27}})^3$, $(\mathbf{1})^3$ and $\mathbf{1}\cdot \mathbf{27}\cdot\overline{\mathbf{27}}$ couplings. While the $(\overline{\mathbf{27}})^3$ couplings are quasi-topological, the $(\mathbf{27})^3$ explicitly depend on the Ricci-flat metric on Calabi-Yau.

In this dissertation, we explore recently developed techniques for calculating the normalized Yukawa couplings on various Calabi-Yau manifolds. In Chapter 2, we describe a novel architecture, …

Counting Kelp: Development And Assessment Of Modelling Approaches To Improve Understanding Of Kelp Bed Abundance And Resilience In The Gulf Of Maine, Constance N. Tyler

Doctoral Dissertations

Kelp habitats in the Gulf of Maine are threatened by rising ocean temperatures and marine invasions. The replacement of kelps with red turf macroalgae fundamentally alters these habitats and disrupts the ecosystem services they provide. Thorough assessment and monitoring of kelp habitats is needed for proper conservation of these habitats, but most long-term monitoring is performed using traditional survey methods that are restricted in the amount of space they can cover. Habitat modelling approaches are required to expand our knowledge of Gulf of Maine kelp habitats, and to better understand the interactions between kelp and red turf habitats across the …

Verifying Interchange Reconnection Models For Magnetic Switchbacks Using The Parker Solar Probe And Mms, Emily Owen Mcdougall

Doctoral Dissertations

Ever since their initial observation by the Ulysses probe, many models of magnetic switchbacks were put forth, but relatively little empirical evidence exists to verify these models, especially in terms of the ions that make up the accompanying plasma. I take energetic particle data from the Parker Solar Probe within switchbacks to provide experimental evidence to bolster the interchange reconnection driven models with particular interest in the interchange reconnection driven linear model. Statistical Analysis of switchbacks in the vicinity of CMEs, solar flares, and high-speed streams show properties consistent with the linear interchange reconnection model, and an analysis of switchbacks …

The Assessment Of Language, The Language Of Assessment: Understanding How Language Teachers Support Dynamic, Communicative Language Learning Through Assessment, Rebecca Kelley

Doctoral Dissertations

As language classrooms in K-12 schools in the United States seek to promote students’ proficiency in the language they teach and to prepare students for a multilingual world, the role of assessment in these classrooms is often overlooked. This study draws from theories of formative and dynamic assessment, as well as a socially-constructed view of language and language learning, in order to examine the way in which secondary language teachers plan for, elicit, interpret, and use evidence from classroom assessments in such a way that promotes and supports the language learning happening in the classroom. Through a series of three …

Fine Structure Of Magnetic Reconnection: Impact On Reconnection And Dissipation Rates, Steven Ver Bryck Heuer

Doctoral Dissertations

Magnetic reconnection is a fundamental process in magnetized plasmas where stored magnetic energy is converted to heat and kinetic energy. The objective of this thesis is to examine the role of small-scale structure of the reconnection region and the background plasma conditions on the rate that reconnection converts and dissipates magnetic energy. This is done using in situ data from NASA’s Magnetospheric Multiscale (MMS) mission and particle-in-cell (PIC) simulations of reconnection for different regimes. First, we introduce a new technique for measuring the reconnection rate and demonstrate its accuracy for the simplest regime of reconnection. Next, we show that it …

Resolving The Role Of Wave-Induced Pressure Gradients On The Movement Of Sediments In Nearshore Environments, Melissa Marry

Doctoral Dissertations

Characterizing the hydrodynamic forces responsible for the initiation of sediment motion is fundamental for improved understanding of large-scale sediment transport processes in nearshore environments. Traditional sediment transport models assume incipient sediment motion is only driven by the force applied by bed stress (Bagnold, 1966; Shields, 1936) while more recent work has shown that incipient motion is influenced by the forcing of the horizontal pressure gradient due to surface gravity waves (Foster et al., 2006; Frank et al., 2015; Sleath, 1999). Wave-induced vertical pressure gradients can also destabilize the sediment bed through the process of momentary liquefaction (Florence et al., 2022b; …

Technologies To Support Remote Work For Collaborative Groups, Alberta Ansah

Doctoral Dissertations

The nature of work continues to evolve, particularly in the aftermath of the COVID-19 pandemic. While a substantial number of employees have returned to traditional, in-person work environments, many continue to engage in remote or hybrid work arrangements. Online meetings are a significant aspect of remote work, and while there has been a significant increase in this area, there are still aspects of these meetings that are not fully understood. Existing research in this area has primarily focused on the development of tools to facilitate meeting execution and content management. In contrast, relatively few studies have explored the social dynamics …

Eastern Oyster, Crassostrea Virginica, Genomics In A Well-Mixed Estuarine System: Examining Population Structure, Viability, And Response To Stressors, Alyssa Strickland

Doctoral Dissertations

Eastern oysters, Crassostrea virginica, are foundational estuarine species that contribute to a variety of ecosystem services including water filtration, nutrient cycling, habitat creation, and shoreline protection. However, populations have declined due to disease, overharvesting, habitat loss, and climate change, especially in northern systems such as New Hampshire’s Great Bay Estuary (GBE), located in the Gulf of Maine, one of the world’s fastest warming waters. This dissertation uses genomic and transcriptomic approaches to understand the drivers of population structure, decline, and resilience in GBE oyster populations, aiming to aid restoration and aquaculture. Chapter 1 used low-coverage whole-genome sequencing to understand population …

Uncovering The Plant-Microbe-Permafrost Paradigm As It Relates To Soil Priming And Arctic Carbon Cycles, Sean Robert Schaefer

Doctoral Dissertations

Permafrost, or perennially frozen soil, covers approximately 25% of the northern hemisphere and contains over half of the world’s soil organic carbon stocks. Permafrost-affected regions are rapidly warming, resulting in ecosystem changes including permafrost thaw and a shift from sedge-dominated to shrub-dominated plant communities. As permafrost thaws, it releases previously unavailable compounds to plants and microorganisms. Plant root inputs can then stimulate the decomposition of thawed permafrost, increasing greenhouse gas emissions in a process called priming. Permafrost thaw increases the decomposition of previously frozen soil organic matter (SOM); however, the extent of decomposition is highly dependent on plants and their …

Its participants engage in mentorship training and professional development, facilitate group mentoring, and draw attention to barriers women and non-binary genders face in physical oceanography. MPOWIR was created to increase the retention of women in physical oceanography in early career stages but has unexpectedly benefited the MPOWIR community beyond graduate students and early career professionals. Senior leaders participating as mentors in MPOWIR report a renewed sense of purpose, new research collaborations, a chance to …

Long-Term Patterns In The Relative Abundance Of Common Snook As A Factor Of Shifting Environmental Conditions In The Florida Coastal Everglades, Jordan A. Massie, Ryan J. Rezek, Rolando O. Santos, W. Ryan James, Natasha M. Viadero, Ross E. Boucek, Jennifer S. Rehage

Marine Science

Objective Environmental variability as a factor of climate change and water management can result in fluctuations in the abundance and distribution of fish populations from year to year, with either negative or positive effects depending on behavioral and physiological requirements and the ability to adapt to changing conditions. Variability in water levels can also influence prey availability, affecting predator abundance in seasonal foraging areas. In this study, our objective was to better understand how environmental variation has affected the relative abundance of Common Snook Centropomus undecimalis in the freshwater/estuarine habitats of Everglades National Park. Methods Electrofishing data over 17 years …

Linking Hydrology, Temperature, And Energetics: Global Change Implications For The Foraging Ecology Of A Generalist Predator, Mack White, W. Ryan James, Justin S. Lesser, Ryan J. Rezek, Jonathan R. Rodemann, Ross E. Boucek, Rolando O. Santos, Jennifer S. Rehage

Marine Science

Objective: The objective of this study was to quantify the effects of temperature, hydrology, and body size on the diet and energy requirements of a generalist predator, Common Snook Centropomus undecimalis (hereafter, “snook”), to gain a better understanding of predator–prey dynamics in the wake of global change. We first ask how temperature, hydrology, and body size influence the occurrence of fish, invertebrates, and empty stomachs in the diet of snook. Next, we model the energetic requirements of snook as a function of body size and temperature. Last, we use predation simulations to test how changes in prey quality, together with …

Quality Improvement Project The Role Of Targeted Education And Its Impact On Self-Efficacy And Cognitive Impairment Recognition Among Medical Assistants, Jicky Guzman

Doctor of Nursing Practice Projects

Primary care teams develop lasting relationships with patients that can reveal subtle cognitive changes during routine visits (e.g., identity verification and brief mobility checks). Yet, cognitive decline often goes unnoticed and poorly documented, which can lead to delayed care. This quality improvement (QI) project addressed a gap in the detection of mild cognitive impairment (MCI), such as Alzheimer’s disease (AD), among frontline staff. It assessed whether an educational intervention could improve self-efficacy in recognizing early cognitive impairment, measured by the General Self-Efficacy Scale (GSES). Guided by Bandura’s Self-Efficacy Theory and Lewin’s change model, a quasi-experimental pretest–posttest study was conducted at …
