Aerosolization tests were conducted in a controlled test chamber …

Cortical Bone Density And Thickness Assessment Of Intraradicular Sites In Adolescent Patients Using Cbct Imaging, Sara Endo

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: The indications for the use of cone beam computed tomography (CBCT) in orthodontics has grown since it was first introduced and dentists are discovering new ways that 3D images enhance diagnosis and treatment planning. Evaluating bone quality and quantity can be measured as bone density and thickness in CBCT imaging and is helpful for temporary anchorage device (TAD) placement in orthodontic treatment. TADs rely on primary stability and are commonly used in orthodontic treatment to increase anchorage and expand the limit that nonsurgical orthodontics can provide.

Objectives: This study aims to assess the bone thickness and density at different …

Correlation Between Maxillary Transverse Width, Alveolar Housing Width And Palatal Bone Thickness: A Cbct Retrospective Study, Eric G. Hollensbe

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background:

Accurate assessment of transverse maxillary dimensions and surrounding bone morphology is critical for safe orthodontic treatment planning. Orthodontic expansion should remain within the biological limits of the alveolar housing and palatal bone to prevent adverse periodontal outcomes, including dehiscence, fenestration, and gingival recession. Standard diagnostic methods, such as dental casts and two-dimensional radiographs, offer limited information about the three-dimensional anatomy that restricts orthodontic tooth movement. Cone-beam computed tomography (CBCT) provides detailed evaluation of skeletal dimensions and cortical bone boundaries. This study aimed to examine the relationships among maxillary transverse width, alveolar housing thickness, and palatal thickness using CBCT imaging. …

The Impact Of Youth Sport On Occupational Balance: A Survey Study, Sean Jones

UNLV Theses, Dissertations, Professional Papers, and Capstones

Youth sport has been highly researched, exploring both positive and negative health impacts (Adetunji & Akendutire, 2017; Brengtsson et al., 2025; Conway, 2024; Hoffman et al., 2022). Despite the high prevalence of youth sport participation, and variability of health-related outcomes, there has been no research regarding the impact youth sport participation has on occupational balance, an occupational therapy concept that has been linked with overall health and well-being (Park et al., 2021).

Harnessing Backcasting To Identify Drivers Of Critical Warming At Hoover Dam Using Hydrodynamic And Machine Learning Models, Eunice Ledres

UNLV Theses, Dissertations, Professional Papers, and Capstones

Elevated water temperatures can pose a significant threat to dam infrastructure, potentially damaging turbines, overheating internal components, and forcing generator shutdowns. This study uses a backcasting framework to evaluate how future scenarios may result in elevated water temperatures. Backcasting defines undesirable outcomes and works backward to identify the conditions that lead to them. The developed backcasting framework integrates 3D physics-based simulations with a Long-Short Term Memory (LSTM)surrogate model and SHapely Additive exPlanations (SHAP) interpretation. The combination captures temporal water temperature dynamics and quantifies the contributions of different drivers to elevated water temperature releases. As proof of concept, these methods are …

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 …

Bodies Under Command: A Feminist-Foucauldian Narrative Analysis Of Institutional And Cultural Betrayal In Military Sexual Misconduct, Chelsea Wheeler

UNLV Theses, Dissertations, Professional Papers, and Capstones

The military continues to experience alarming rates of sexual aggression, reaching epidemic levels. While all people can experience sexual aggression, women, compared to men, are more likely to experience this, despite women making up only 17 percent of the military. Throughout history, the military has demonstrated several instances of reactive attempts at combating the concerns of sexual aggression; however, these attempts have not been successful. From a feminist-Foucauldian lens, this dissertation research explores narratives of service members to gain a more in-depth understanding of the systemic dynamics that contribute to institutional and cultural betrayal in sexual victimization experiences. Additionally, this …

Multiple Interest Holder Perspectives Of The True Grit Sci Residential Program: A Mixed Methods Program Evaluation, Keara Mcnair

Seton Hall University Dissertations and Theses (ETDs)

Young adults with spinal cord injury (SCI) face significant challenges during the transition to adulthood, including barriers to independence, community participation, and psychosocial adjustment (Ingimarsdóttir et al., 2023; Zebracki et al., 2010). Current rehabilitation models in the United States prioritize short-term physical recovery and offer limited support for the developmental and contextual needs that shape long-term outcomes after SCI, particularly during transitions from inpatient rehabilitation to the community (Anderson et al., 2024; Bryden & Gran, 2024). Community-based programs may help address these gaps, though few have been rigorously evaluated using implementation science frameworks that attend to health equity, contextual influences, …

Seton Hall University Dissertations and Theses (ETDs)

Wrap-Around Support Services for the Spanish-Speaking Immigrant Student and School Belonging

Genesi Miles, Ed. M

Immigrant students and families continue to navigate systemic barriers that limit equitable access to educational opportunities and meaningful school engagement. Language differences, racism, transportation challenges, childcare constraints, intimidation, and concerns related to legal status frequently hinder immigrant families’ participation in schools (Sibley & Brabek, 2017). In New Jersey, approximately one-third of immigrant parents live below 200 percent of the federal poverty line (Hofstetter & McHugh, 2021), further compounding these challenges. Despite these realities, many U.S. schools lack intentional planning to support immigrant populations, a gap …

Incivility In Nursing: The Experience Of Registered Nurses In The Emergency Department, Karen Voorhees

Seton Hall University Dissertations and Theses (ETDs)

The American Association of Colleges of Nursing (AACN) predicts that due to the anticipated retirement of the “baby boomer” generation coupled with an expanded need for medical care across the United States, the need for nurses will expand 6% by 2032 (AACN, 2024). This need will be impeded by nurses leaving the profession due to feelings of a poor work environment, burnout and job dissatisfaction. Incivility in nursing has been shown to be a contributor to nurses leaving their current work environments or the profession of nursing entirely.

Incivility in nursing has roots in organizational psychology and has been shown …

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

Through the lens of self-determination theory, this study aims to describe the internal and external factors that teachers describe as “playing a role” …

Theosis And The Morality Of Happiness: Investigating The Implications Of The Deification Doctrine In Aquinas, Emma Newgarden

Seton Hall University Dissertations and Theses (ETDs)

This thesis examines the implications of a connection between the doctrine of deification or theosis (often summarized by the patristic axiom that God became man so that man might become God) and a Christian morality of happiness, an understanding of the moral life as that which comprises our true human flourishing—a transformative growth in virtue by which we grow in our capacity to realize our final telos of union with God. Deification, traditionally more strongly associated with Eastern Christian theology, has not typically been discussed in relation to the morality of happiness, arising primarily within the discourse of the contemporary …

Potential Innate And Adaptive Roles Played By Γδ T Cells In A Bacterial Immunization Model, Lee Anne Talbot

Seton Hall University Dissertations and Theses (ETDs)

Francisella tularensis is a highly infectious intracellular bacterium and the causative agent of tularemia, with pulmonary infection resulting in severe disease and high mortality if untreated. While protective immunity to F. tularensis has been largely attributed to CD4⁺ T cell–mediated IFN-γ responses, the contribution of γδ T cells to mucosal immunity and vaccine-induced protection remains poorly defined. The objective of this study was to characterize the role of γδ T cells during primary pulmonary infection with F. tularensis live vaccine strain (LVS) and following intranasal immunization with inactivated F. tularensis (iFt) prior to LVS challenge.

Exploring Health Insurance’S Role In Chronic Disease Management Among Hispanics, Romelyn Dones

Seton Hall University Dissertations and Theses (ETDs)

This qualitative study examined how insured non-English- and English-speaking Hispanic adults perceive the role of health insurance in the management of chronic disease. Chronic conditions remain a leading cause of morbidity in the United States, and although prior research suggests that insurance coverage improves access to care, it does not always enhance how individuals understand or utilize support for chronic disease management. Limited research has explored how individuals with chronic conditions interpret the role of insurance in their daily self-management practices, particularly among Hispanic populations. Guided by Andersen’s Behavioral Model of Health Services Use, this study explored how contextual, enabling, …

Principals’ Perceptions On How Artificial Intelligence (Ai) Is Used In Schools By Administrators, Teachers, And Students: A Mixed Method Research Study, Dianna M. Sopala
