Anomaly Detection Using Unsupervised Machine Learning Algorithms: A Simulation Study, Edmund F. Agyemang

School of Mathematical & Statistical Sciences Faculty Publications

This study presents a comprehensive evaluation of five prominent unsupervised machine learning anomaly detection algorithms: One-Class Support Vector Machine (One-Class SVM), One-Class SVM with Stochastic Gradient Descent (SGD), Isolation Forest (iForest), Local Outlier Factor (LOF), and Robust Covariance (Elliptic Envelope). Through systematic analysis on a synthetically simulated dataset, the study assessed each algorithm’s predictive performance using accuracy, precision, recall, and F1 score specifically for outlier detection. The evaluation reveals that One-Class SVM, Isolation Forest, and Robust Covariance are more effective in identifying outliers in the synthetic simulated dataset, with Isolation Forest slightly outperforming the other algorithms in terms of balancing …

Impact Of Delphi-Developed Rubrics On Rater Consistency In 14 Cfr 141 Flight Training Assessment Environments, Lewis Robert James Archer

Theses and Dissertations

Pilot schools operating in accordance with 14 CFR 141 provide a substantial supply of pilots to the aviation industry. Recent high industry demand for pilots has created turnover among the flight instructor workforce, often considered an entry-level position used by aspiring aviators to build flight experience. This in turn means that check instructors, evaluators who are often selected from the more senior flight instructor population at a pilot school, are generally less experienced than in the past. Anecdotal evidence suggests that there is low consistency among these check instructors when conducting performance-based assessments. This study sought to determine the existing …

Nature-Based Solutions For Flood Risk Mitigation: Mapping And Hydrological Modeling In An Under-Resourced Urban Area On The Mississippi Gulf Coast, Jennifer Makenzie Holifield

Master's Theses

Flooding is the most frequent and costly disaster in the United States, affecting people disproportionately based on environmental, societal, and economic limitations. Through stakeholder engagement, open-access research, and nature-based solutions (NBS), ecology and hydrology can be bridged with local-scale politics to raise awareness of local issues and form strong interdisciplinary bonds. I approached nature-based equity from a ground front, in which I engaged with local stakeholders and city officials to gain insight and calibration on flooding experiences and flooding presence within Moss Point, MS. This engagement helped calibrate GIS models, from which, I found that the flooding hazards of Moss …

Modeling Hourly Storm Surges Using Deep Learning Techniques, Md Abu Zafor

Master's Theses

Storm surges cause coastal flooding, one of the most devastating coastal hazards. Accurate modeling of storm surges is essential for predicting and mitigating these impacts. Traditional approaches model surges at individual tide gauges and often focus on daily time scales, leading to data redundancy and limiting their ability to capture sub-daily variability. This study addresses these limitations using deep learning (DL) algorithms to model hourly surges simultaneously at multiple tide gauges along the U.S. East Coast and Gulf of Mexico. Three algorithms, Convolutional Neural Network (CNN), Long Short-Term Memory (LSTM), and a hybrid ConvLSTM are employed to model surges using …

Increasing Pride Skills For Child Engagement Using Ipcit With Children With Autism Spectrum Disorder, Jordan Etherington

Master's Theses

Many children with autism spectrum disorder display elevated levels of problem behaviors, such as aggression and defiance, in addition to symptoms characteristic of autism, such as deficits in social communication and interaction. Parent Child Interaction Therapy (PCIT) is a behavioral parent training program designed to improve problem behavior in young children by teaching parents to use skills that reinforce appropriate behaviors. In addition, the interactive nature of PCIT may help children with autism increase the rates at which they engage and interact with their caregivers. There are many barriers to treatment completion in PCIT, including high attrition rates due to …

Just Deserts: The Moral Foundations Of Antagonistic Personality In Social Aggression, Summer Steely

Master's Theses

Social aggression is associated with adverse psychosocial consequences such as anxiety, depression, isolation, reciprocal violence, and suicidality (Zhu et al., 2024). Psychopathic personality traits and moral deficits have been linked to antisocial behavior, including social aggression; however, the role of moral value systems and trait moral disengagement in the context of social aggression is less clear. A more granular analysis of their utility may illuminate new pathways toward intervention. To advance this goal, the present study explored the relationships between the values of Moral Foundations Theory and social aggression among college students (N = 301). Two moral foundations (i.e., care …

Intensive Postpartum Antihypertensive Treatment (Ipat) And Healthy Lifestyle Education: Study Protocol For A Pilot Randomized Controlled Trial For Patients With Hypertensive Disorders Of Pregnancy, Anna Palatnik, Nadine Sunji, Zaira Peterson, Jennifer M. Ohlendorf, Amy Y. Pan, Jacquelyn Kulinski

College of Nursing Faculty Research and Publications

Background

Hypertensive disorders of pregnancy (HDP) complicate about 10% of pregnancies and lead to postpartum hospital readmissions and cardiovascular complications. Following HDP, vascular dysfunction could persist and accelerate the trajectory of cardiovascular disease risk. The benefits of intensive blood pressure (BP) control following HDP have not been adequately investigated. Therefore, no standard guidelines exist to guide the management of mild-to-moderate hypertension in the postpartum period, leading to a wide variation in clinical practice. The present study will investigate the effect of intensive BP control and healthy lifestyle education on maternal cardiovascular health (CVH) and vascular function following HDP.

The Nursing Human Capital Value Model, Olga Yakusheva, Kathryn A. Lee, Marianne Weiss

College of Nursing Faculty Research and Publications

Nursing's economic value is presently framed within the dominant “outcomes-over-cost” value framework. Within this context, organizations employing nurses often use nursing budget reductions as a cost-minimization strategy, with the intent of retaining high quality outcomes. However, persistent issues such as nurse understaffing, burnout, and turnover threaten healthcare systems' capacity to deliver the quality, equitable, affordable patient care that the public requires. In this paper, we propose a new conceptual model and definition of nursing's economic value. The model development is guided by the convergence of three classic economic frameworks: human capital theory, production theory, and value theory. Grounded in these …

Proactive And Reactive Sibling Aggression And Their Mediating Effects On The Relationship Between Exposure To Parental Violence And Adulthood Intimate Partner Violence Perpetration, Ayleen Flores, Ruby Charak

Psychological Science Faculty Publications

It is generally understood that individuals who experience exposure to parental violence (EPV) during childhood may come to perpetrate violence, but not all will. Research has shown that individuals who experience EPV can model maladaptive modes of problem-solving that can later be seen in sibling relationships as aggression. This can lead to a heightened risk of adulthood intimate partner violence perpetration (IPV). This study aimed to examine the mediating role of proactive and reactive sibling aggression in the associations of three forms of childhood EPV—violence directed from mother-to-father, father-to-mother, bidirectional—and perpetration of sexual and physical IPV types during adulthood. Participants …

Physics Faculty Publications and Presentations

We present a new empirical framework modeling the metallicity and star formation history (SFH) dependence of X-ray luminous (L ≳ 10³⁶ erg s⁻¹) point-source population X-ray luminosity functions (XLFs) in normal galaxies. We expect that the X-ray point-source populations are dominated by X-ray binaries (XRBs), with contributions from supernova remnants near the low luminosity end of our observations. Our framework is calibrated using the collective statistical power of 3731 X-ray detected point sources within 88 Chandra-observed galaxies at D ≲ 40 Mpc that span broad ranges of metallicity (Z ≈ 0.03–2 Z_⊙), SFH, …

To preserve the future of juries and jury trials, the National Center for State Courts (NCSC) convened a meeting of representatives from a broad array of justice system stakeholders as a project under the Justice for All Reauthorization Act (JFARA). To frame the stakeholder discussions, NCSC employed strategic foresight, a methodological approach designed to explore a range of possible futures of juries and jury trials within the American justice system as a vehicle for identifying critical vulnerabilities within the current jury system and proposing targeted strategies to preserve and strengthen jury trials. Critical vulnerabilities are those areas of weakness that …

Colonial Policy, Ecological Transformations, And Agricultural “Improvement”: Comparing Agricultural Yields And Expansion In The Spanish And U.S. Philippines, 1870–1925 Ce, David Max Findley, Noel Amano, Ivana Biong, Greg Bankoff, Patricia Irene Dacudao, Francis A. Gealogo, Rebecca Hamilton, Ruel Pagunsan, Patrick Roberts

History Department Faculty Publications

Burgeoning global trade and colonial policies promoted transformations in land use and agriculture throughout tropical regions in the 19th and 20th centuries, but the local and regional ecological consequences of landscape changes are still being identified and analysed. The Philippine Archipelago, which experienced successive colonial regimes across more than 7100 islands, exemplifies the multiplicity of ecological outcomes produced by these transformations. To better characterise diverse landscape change, we use colonial censuses and datasets to assess land use, production and agricultural yields in the Philippines during the late Spanish and early U.S. colonial periods (ca. 1870–1925). Our novel digital, quantitative analysis …

We Are All Cafeteria Originalists Now (And We Always Have Been), Jack M. Balkin

William & Mary Bill of Rights Journal

In Memory and Authority, I argue that Americans, both in politics and in constitutional culture, are "‘cafeteria originalists.’ They pick and choose when to follow the views of the founders, framers, or adopters (as they understand them) and often artfully recharacterize these principles to support contemporary political and legal arguments.” Like customers in a cafeteria who take the chocolate cake and leave the boiled kale, Americans pick the features of the framers they like to support their arguments, and leave other, less savory, features behind.

My central claim is that cafeteria originalism is not a pathology or a …

Invocations Of Memory In State Constitutional Law, Fred O. Smith Jr.

William & Mary Bill of Rights Journal

This Symposium Essay discusses the roles of history and memory within the realm of state constitutional law. Building on Professor Balkin’s observations, I offer two claims. The initial argument, delineated in Part I, is descriptive. While the practice of state constitutional law often mirrors that of federal constitutional interpretation, the use of history in state constitutional interpretation has unique characteristics, both with respect to text and ethos. Regarding textual analysis, understanding the language of a state constitution often involves engaging with a concept referred to by some scholars as “interconstitutionalism.” This phenomenon occurs when a single governmental body has operated …

Reproductive Injustice, Feminist Resistance, And The Uses Of History In Constitutional Interpretation, Serena Mayeri

William & Mary Bill of Rights Journal

Part I examines the erasure of constitutional memory about reproductive injustice and feminist mobilizations and the benefits of recovering these histories. Part II explores how cases involving women’s subordination provide particularly effective illustrations of the anti-democratic, even absurd, results the current supermajority’s approach to history-and-tradition is designed to produce. Part III concludes with a brief discussion of some sites for the expansion of constitutional memory about reproductive control and freedom.

This abstract has been taken from the author's introduction.

Freedom And Families: Reconstruction Republicans And The Question Of Women's Reproductive Autonomy, Kate Masur

William & Mary Bill of Rights Journal

This Essay proceeds in three Parts. In the first, I illuminate how congressional Republicans discussed women, gender, and families in the context of policymaking associated with abolishing slavery. Many Republicans worried that enslaved people’s family relationships had been damaged by the imposition of slavery and sought to impose on freedpeople what they saw as normative family values, including by encouraging heterosexual marriage and by insisting on patriarchal gender roles within families. Second, I show that Republicans were at pains to demonstrate that when they talked about equality, they meant race but not gender. Finally, I reflect on the limits of …

Downtown Hattiesburg: In History And Memory, Joseph Reosti

Honors Theses

This paper explores how public memory of Downtown Hattiesburg has been shaped by race, class, and historical change, drawing primarily on oral history interviews conducted by the author. Once the heart of the city, Downtown Hattiesburg experienced significant decline from the 1970s onward due to suburbanization, white flight, and demographic shifts. In response, the 1970s saw the emergence of a historic preservation movement focused on revitalizing memories of the city's early 20th-century prosperity (1910-1929), often idealized as a period of economic success even despite racial segregation. Many interviewees identified this era as the city’s "golden age," despite its deeply inequitable …

Tc-Ptp-Mediated Regulation Of P38 Mapk Pathway Promotes Uvb-Induced Apoptosis In Skin, Lindsey Susie Shim

Theses and Dissertations

T-cell protein tyrosine phosphatase (TC-PTP) is a non-receptor PTP that has been shown to have various roles in signaling pathways. Our previous studies have demonstrated that the TC-PTP deficiency in the epidermis can exacerbate hyperplastic response by inducing epidermal cell proliferation in response to tumor promoter TPA or UVB exposure. This implies that TC-PTP plays a tumor-suppressive role in the epidermis and provides protection against UVB radiation, which is well known to contribute to skin cancer development. The p38 mitogen-activated protein kinase (MAPK) is one of serine/threonine kinases that are activated through environmental stress including UVB. It has been demonstrated …

This study explores the impact of these certification routes on teachers’ abilities to support student achievement, address diverse learning needs, and manage additional duties. Surveying secondary math teachers in the Rio Grande Valley, …

A Phenomenographic Analysis Of Undergraduate Student Perceptions Of The Geosciences And Geoscience Careers, Leah M. Wiitablake

All Dissertations

The climate crisis is upon us, whether we like it or not, and its undeniable effects are evident. Take, for example, Hurricane Helene, which caused unimaginable devastation to what was once considered a “climate haven,” Asheville, NC (Andreoni, 2024; Medina & Fausset, 2024). Hurricane Helene made landfall as a Category 4, jumping from a Category 1 in less than 24 hours (Andreoni, 2024), and is noted by the National Hurricane Center as a major hurricane (National Hurricane Center & Central Pacific Hurricane Center, 2024). With the Earth now unlikely to remain below 1.5°C of warming (IPCC, 2023b), perhaps we can …

Real-Time Motion Augmentation And Synthesis For Animating The Hands And Eyes Of Virtual Humans And Avatars, Ryan Canales

All Dissertations

Virtual Reality (VR) enables users to interact within virtual worlds via an embodied virtual representation of themselves called an “avatar”. Because avatars are essential for immersive experiences, it is important to consider how altering or augmenting avatar motion affects virtual experiences. This dissertation aims to improve virtual experiences by addressing some of the many challenges in animating avatars and virtual humans.

In our first study, we addressed the lack of tactile feedback during virtual grasping by using visual feedback techniques. We augmented the avatar’s hand motion to remain outside virtual objects (“outer hand”) even when the user’s hand penetrated them. …

Quantifying Greenhouse Gas Exchange And Ecosystem Services In Ecosystems Managed For Nature-Based Solutions Using Eddy Covariance, Remote Sensing, And Models, Lucas Clay

All Dissertations

As global temperatures rise due to climate change, nature-based solutions are increasingly being used to restore nature and to remove carbon from the atmosphere. Nature-based solutions draw on methodologies such as ecological forestry and improved forest management to reduce emissions and maximize resilience. These protocols are still in their infancy and additional measurements and case studies are important to optimizing these protocols. Herein this dissertation we describe multiple measurement methodologies for both greenhouse gas (GHG) emissions and for ecosystem services. In coastal wetland ecosystems, the need for GHG measurements is paramount to understanding the ability of these ecosystems to reduce …
