Examining The Experiences And Career Of A Highly Effective Orchestra Teacher: A Narrative History, Charlotte A. Hebert

Masters Theses, 2020-current

Much of the available literature on the status of string education in the United States highlights the need for qualified string teachers. However, limited researchers have analyzed the reflections and perspective of retired string teachers. Retired string teachers have a unique ability to provide insight to preservice and current string teachers from a reflective lens. In this historical narrative study, I examined the 40-year career of orchestra director Laura Mulligan Thomas through her contributions and experiences. I utilized previous string education literature to define an effective string teacher. I employed semi-structured interviews, observations of a string techniques class that Thomas …

Weaving Eigengrau, Olivia Claire Luke

Masters Theses, 2020-current

Weaving Eigengrau explores weaving as both a material ritual and an inquiry about how reality is constructed and can be pulled apart. In this project, weaving becomes a method for redirecting forces into woven patterns and examining the relationship of contradiction by treating the contrasts between light and shadow, stillness and motion, and the fixed and the ephemeral as sculptural aspects. I’m driven by theories of reality: science, myth, and philosophy, and the common threads among them. Across systems of knowledge, reality is depicted in contradiction, and I seek to blur the lines between them. Within this convergence, weaving becomes …

Impact Of Travel Time To Health Facilities On Perinatal Outcomes: A Systematic Review With Narrative Synthesis And Meta-Analysis, Sanam Roder-Dewan, Marwa Ramadan, Paul Ouma, Alexander Manu, Emelda A. Okiro, Natalie Strobel, Bibian N. Robert, Emily Odipo, Peter M. Macharia, Anthony Danso-Appiah, David C. Goodman, Queen Dube, Gagan Gupta, Hema Magge, Karen Edmond

Research outputs 2022 to 2026

Background: Evidence-based global guidance on safe travel time for small or sick newborns who require transfer to health facilities after birth is lacking. A two-hour threshold is frequently cited in low- and middle-income countries (LMICs), while 30 minutes is commonly used in high-income countries (HICs). Although these thresholds are widely referenced, their empirical basis and consistency across levels of newborn care and journey types have not been systematically examined. This study synthesises the evidence linking travel time and perinatal outcomes. Methods: We conducted a systematic review with narrative synthesis and meta-analysis to assess the impact of travel time or distance …

Off-The-Shelf Danger: The Need For Overhauling Faa Regulations To Combat The Misuse Of Commercial And Recreational Drones, Ka Ching "Cyrus" Au

Seattle Journal of Technology, Environmental, & Innovation Law

This article discusses how FAA Part 107 has not kept pace with

advances in drone technology and advocates for a tailored solution for

drones. The increasing accessibility of sophisticated drone technology

presents significant national security and public safety challenges.

Regulatory frameworks posed by the Federal Aviation Administration

(FAA) are insufficient to address these growing concerns. The drone

technology originally marketed and developed for photography,

agriculture, and package delivery is now being repurposed for military use

and illegal activities. In the Russo–Ukrainian war, drones are now used to

carry advanced reconnaissance capabilities or are equipped with remotely

detonated explosives. Along a …

Returning Home: Vocation As A Theological Lens To Foster The Ethiopian Evangelical Church Mekane Yesus’ Holistic Ministry Among Migrant Returnees In Ethiopia, Ebise Dibisa Ayana

Doctor of Philosophy Dissertation

This dissertation examines return migration in Ethiopia, focusing on Ethiopian Domestic Worker Returnees (EDWRs) and the role of the Ethiopian Evangelical Church Mekane Yesus (EECMY) in addressing their holistic needs. Using theological and institutional analysis, the study finds that, although the EECMY affirms holistic ministry as its motto, it lacks clear policies and official statements specifically addressing the spiritual and psychosocial needs of the returnees’.

The research argues that migration and return migration are theological and moral issues that require a holistic response grounded in a Lutheran Theology of Vocation. Such an approach fosters an integrated ministry that attends to …

The Origins Of Chondrite Families, Isabelle M. Perron

UNLV Theses, Dissertations, Professional Papers, and Capstones

Chondrites, a type of primitive asteroid, are thought to have formed from dust and gas early in the life of our Solar System. These chondrites have remained unchanged since their formation, avoiding being melted or differentiated like other rocky bodies have. Due to this unique characteristic, chondrites can give us useful insight into how asteroids, planetesimals, and even the terrestrial planets formed. In order to study chondrites and their formation, I used code developed by Li et al. (2020), which utilizes thermodynamic code GRAINS (Petaev 2009), to see what conditions the chondrites may have originated from. GRAINS uses a variety …

UNLV Theses, Dissertations, Professional Papers, and Capstones

Throughout this creative thesis/magazine, I explore and capture the essence of Chicano culture in the 80s and the role music played, in its simplest form. This project is heavily inspired by my dad and our shared love for music. Growing up in the 80's, pop culture was all around me, constantly; so much so, I never thought twice about it. As I got older, he told me more stories about growing up in L.A. He told me about breakdancing on Venice Beach and riding his bike under the L.A. River bridge. He would tell me stories about parties and how …

Constructing A Laser Stabilization System For Frequency Metrology, Stephanie Letourneau

UNLV Theses, Dissertations, Professional Papers, and Capstones

Frequency metrology and quantum control, which uses light as a tool for measurement and manipulation, relies on spectrally narrow, stable lasers. Often thought of as being perfectly monochromatic and coherent, in reality, the free-running instantaneous linewidth of lasers can be on the order of hundreds of kHz in the millisecond time-frame and drift on the order of tens of MHz over hours. To correct for these instabilities in real-time, a variety of laser stabilization methods have been implemented, including the Pound-Drever-Hall (PDH) method, saturation absorption spectroscopy (SAS), and dichroic atomic vapor laser locking (DAVLL). All of these methods rely on …

Factors Influencing K-12 School Homicide Casualties, Melvin Alexander Vargas Melgar

UNLV Theses, Dissertations, Professional Papers, and Capstones

Kindergarten through 12th-grade (K-12) school homicides, defined as homicides that occurred on the property of a school serving kindergarten through 12th-grade students, account for about 2% of all youth homicides, but are still a serious problem in the United States. From 2000 to 2024, 372 K-12 school homicide incidents have occurred, in which 783 victims were killed and injured. However, prior research tends to either generally focus on youth homicides, school violence, or high-profile school shootings with multiple victims. This study aims to add to the literature by examining various incident-level factors of K-12 school homicide incidents that may influence …

Does Match Matter? Examining The Role Of Student–College Match And First-Year Stem Retention, Christopher J. Shemanski

Seton Hall University Dissertations and Theses (ETDs)

This quantitative study examines how student–college match relates to first-year STEM retention in a nationally representative cohort of four-year, STEM-intending students from the High School Longitudinal Study of 2009 (HSLS:09) linked with institutional data from the Integrated Postsecondary Education Data System (IPEDS). Building on probabilistic approaches to college match, the study first estimates each student’s predicted probability of admission to institutions in five selectivity tiers using high school GPA, standardized test scores, highest mathematics course completed, AP mathematics credits, gender, and socioeconomic status. It then compares the predicted tier with the selectivity of the institution actually attended to classify students …

Quality Improvement (Qi) Project Aimed At Reducing Unnecessary Antibiotic Usage Among Older Adult Patients By Addressing Inappropriate Antibiotic Prescribing In Primary And Long-Term Care Settings, Pamela M. Thomas

Seton Hall University Dissertations and Theses (ETDs)

Antibiotic overuse among older adults remains a significant patient safety and public health concern. Recent national data indicate that approximately 30%–50% of outpatient antibiotic prescriptions may be unnecessary, particularly for viral or self-limiting conditions (Chua et al., 2021). Antimicrobial resistance has been associated with more than 1.27 million deaths globally (Murray et al., 2022). This quality improvement project evaluated a multifaceted antimicrobial stewardship intervention in primary and long-term care settings. Baseline review of 167 antibiotic cases revealed 37.1% were inappropriate or questionable, and 28.7% lacked adequate diagnostic documentation.

“The Hond Hire Helde”: Solidarity, Mirroring, And Foreshadowing Between Helen, Cassandra, And Criseyde In Chaucer’S Troilus And Criseyde, Mallory K. Warner

Seton Hall University Dissertations and Theses (ETDs)

Geoffry Chaucer’s Troilus and Criseyde has divided readers and critics alike when addressing the main female protagonist: Criseyde. The poem follows Criseyde and her love interest Troilus, during the final days of the Trojan War, as the two are thrust together into a tragic affair then ripped apart by outside forces and the consequences of their own choices. By the end of the narrative, Criseyde’s autonomy is stripped from her as she is traded in a hostage exchange to the Greek army. In her last present moment in the poem, Criseyde comes to the realization that remaining true to Troilus …

Nathaniel Hawthorne And The Limits Of Half-Feminism, Jessica Mckenzie

Seton Hall University Dissertations and Theses (ETDs)

This project argues that while Nathaniel Hawthorne creates intellectually complex and emotionally resilient female heroines in The Scarlet Letter and The Blithedale Romance, he ultimately reinforces the patriarchal structures he appears to critique. Through the figures of Hester Prynne and Zenobia, Hawthorne demonstrates a deep awareness of women’s societal oppression and the limitations imposed upon them within nineteenth-century America. However, despite moments of resistance and autonomy, these women are never permitted full liberation, agency, or lasting fulfillment. Their narratives ultimately become constrained by the patriarchal power that denies them independence and sustaining love. Thus, Hawthorne’s work coincides with the …

Within Melbourne: Landscape, Labor, And Material Culture In A Derbyshire Parish, 1650-1750, Mia Powell

Senior Honors Papers / Undergraduate Theses

In May of 1695, a group of inhabitants walked the grounds of the English locality of Melbourne (Derbyshire) and collected demographic data from every household within the parish boundaries. From this perambulation came a uniquely detailed census-type listing. Combining that listing with other available sources, including probate records, criminal litigation, property disputes, financial papers, antiquarian accounts, maps, and enclosure agreements from across seven record offices, this project uncovers the complex social and economic developments experienced by those who lived in Melbourne from 1650 to 1750. To analyze this well-documented parish, this thesis utilizes various methodologies. Nominal record linkage connects Melbourne’s …

Keeping Sight Of The Middle Waters: The Osage Nation's Strategy To Survive Indian Territory, Hannah N. Maxwell

Electronic Theses & Dissertations

The nineteenth century brought novel changes to the whole word, and Indigenous nations were no different. As the United States began the Reconstruction period’s wave of Indian Removal, the Osage Nation employed all sorts of strategies for continued autonomy and provision. Some were governmental, such as signing treaties and seeking new forms of representation. Other times, the Osage made deals with big businesses for an economic boost. The Osage Nation carefully created a new balance to keep settlement from taking their rights to the land. Mostly, however, the Osage Nation accepted new methods and lifestyles while keeping their own culture …

(The) Invisible Threads: Portraiture, Memory, And Relational Endurance, Behnaz Ghasempour

Masters Theses, 2020-current

(The) Invisible Threads is an MFA thesis investigating how invisible interpersonal bonds, collective traces, and communal endurance can be made perceptible through drawing, material, and immersive installation. Drawing from my lived experience as an Iranian woman who has witnessed everyday constraint, collective uprising, and migration, the project asks how the presence of others continues to inhabit the body and shape identity even in conditions of separation and distance. Large-scale self-portraits, layered with other faces on transparent fabrics, copper plates, and stitched threads, position the artist’s own body as a site where personal and collective histories converge, allowing the self to …

Machine Learning Assisted Development Of Al0.2cufemnni High Entropy Alloy Through Selective Laser Melting, Hareharen K Mr

Theses and Dissertations

High Entropy Alloys (HEAs) are an emerging class of advanced materials that have gained significant attention due to their exceptional mechanical strength, thermal stability, and structural performance. Unlike conventional alloys based on a single principal element, HEAs are composed of multiple elements in a near-equiatomic ratio. Despite these advantages, designing HEAs with tailored properties is difficult because of the enormous number of possible combinations and the limitations of traditional trial-and-error methods. To overcome these challenges, this study presents a machine learning (ML) based approach to accelerate the design and development of an HEA.

In this work, a newly designed composition, …

UNLV Theses, Dissertations, Professional Papers, and Capstones

During the communist era in Slovakia from 1948 to 1989, religion was forced into the private sphere and then re-entered into the public sphere when the Communist Party of Czechoslovakia (KSČ) collapsed in 1989. This research aims to answer how the communist state and religious community interacted during communism and how a democratic state and religious community interacted post-communism. This paper focuses on how people preserved their religion, how secularization was rejected, and how religion re-entered the public sphere after communism ended. To answer these questions, I conducted oral interviews, primarily with the townspeople of Topoľčany, Slovakia, and this includes …

Transboundary Groundwater Flow Between Niger And Nigeria In The Iullemeden Aquifer System, Gare Ambrose-Igho

UNLV Theses, Dissertations, Professional Papers, and Capstones

Groundwater is important in regions where water resources are not abundantly distributed such as arid and semi-arid regions. In many countries in Africa, groundwater serves as the most reliable source of water supply and supports over 50% of the African population. Groundwater is stored in underground water-bearing permeable rocks, rock fractures, or unconsolidated materials known as aquifers. Groundwater can be transboundary, meaning it crosses international political boundaries between two or more sovereign states. Transboundary aquifers are prone to overexploitation that depletes the groundwater resource and can cause a lowering of the water table and possible ground subsidence. Overexploitation in transboundary …
