Quantifying Contributions Of Sonar Systems On Marine Soundscapes: A Statistical And Machine Learning Analysis, Reilly Jacob Lessard

Master's Theses and Capstones

A variety of elements are used to characterize marine soundscapes, including natural and anthropogenic sound. One anthropogenic activity that potentially contributes to marine soundscapes, but is not sufficiently understood, is the use of different types of ocean-mapping sonar systems. Sonar systems are used abundantly in marine environments for purposes such as ocean floor mapping and military security purposes [Ryu et al., 2023] [Marszal and Salamon, 2013]. The systems used to conduct this research are the Kongsberg TOPAS PS40 sub-bottom profiler and the RESON SeaBat T51-R multibeam echosounder, along with SoundTrap recorders, which were deployed in the Gulf of Maine. Periods …

How Human Personality Will Change With The Use Of Artificial Intelligence, John Mayer

UNH Personality Lab

INTRODUCTION: Human personality changes in response to new habits, situations, and maturation, among other causes. As people interact with artificial intelligence (AI), their personalities are likely to change, from their emotional responses to their self-concept.

METHODOLOGY: This theoretical account draws together empirical studies of how personality changed in response to past technological innovations, changes in personal interactions observed in people’s AI usage, changes that arise from the use and disuse of cognitive skills, and works on the self-concept. Research reports in the review were selected according to their relevance and quality.

THEORETICAL STATEMENT: While AI becomes increasingly human-like, humans increasingly …

The Institute for Health Policy and Practice (IHPP) at the University System of New Hampshire commissioned Scientific Health to conduct an evidence-based review of the relationship between criminal justice system involvement and health outcomes. This research synthesized findings from recently published, peer-reviewed academic literature and relevant reports to examine how correctional system involvement affects physical health, mental health, and overall well-being among incarcerated individuals, their families, and communities. The review identified common themes related to behavioral health, chronic conditions, and systemic impacts, providing insight into the broader health implications of mass incarceration and deinstitutionalization. These findings aim to inform policy …

Sally Walton's Will: Reuniting The Andrews Families Of Western Maine And Beyond, Kathrine C. Aydelott

Faculty Publications

This article demonstrates how the 1871 probate file of Sally (Andrews) (Andrews) (Clark) Walton of Paris, Maine, resolves decades of genealogical confusion among Andrews families of western Maine. Analysis of her will, codicils, and probate accountings reconstructs a fragmented sibling group and definitively distinguishes two men named Perez Andrews whose identities had long been conflated. The evidence firmly links Darius Andrews of Sumner, Perez Andrews of Buckfield and Penobscot County, and several previously untraced Andrews siblings to a single parental family headed by Ebenezer Andrews Jr. and Sarah (Elliot) Andrews. Moving beyond questions of descent, the article shows how probate …

Innocent Fun Or Unhealthy Habit: What's Your Game? Personality And Engagement With Video Games, Derrick Angier

Doctoral Dissertations

This thesis reports two exploratory studies of similar design, both of which investigated which gamers might be at risk for problematic or aggressive gaming. In both Study 1 (N = 480) and Study 2 (N = 761), which served as a replication, four composite scores representing participants’ personality attributes were created from big traits of the HEXACO—Honesty-Humility, Emotionality, Extraversion, Agreeableness, Conscientiousness, and Openness, a people-centered intelligence—personal intelligence—and motives for gaming. These composite scores and the subordinate individual variables were used to predict lifespace measures of unhealthy/healthy gaming behaviors and aggressive/pro-social in-game interactions. Lifespace scales capture a person’s reports of their …

Synthetic And Analytical Methods For Metal Targeting Peptides For The Sensing And Removal Of Metals Across Various Matrices, Emily Andrews

Doctoral Dissertations

Metal chelators developed from peptides boast favorable attributes such as low toxicity, ease of synthesis, and high tunabilty to the target metal ion. It is for these reasons that peptides are used for metal sensing and sequestration in the body and environment. Herein, two unique sets of metal targeting peptides are discussed: (1) bifunctional Szeto-Schiller and Kelley peptide probes to signal the presence of and remove labile iron (Fe2+ and Fe3+) in the mitochondria, to mitigate the progression of Ferroptosis and (2) Pb2+ targeting peptides designed to exist in aqueous environments for the removal of toxic lead ions from waterways. …

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 …

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 …

Investigations Into Prior Knowledge And Self-Efficacy As Predictors Of Exam Performance In General Chemistry, And Student Interactions With Chemistry Textbooks, Gordon Hunter

Doctoral Dissertations

The first chapter addresses the validity and reliability of the Motivated Strategies for Learning Questionnaire (MSLQ) as a tool for chemistry education research. The study shows that the original MSLQ did not meet modern standards of reliability and presents a modified version that better captures self-efficacy in chemistry-specific contexts. 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 …

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 …

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 …
