Mimbres Social Organization At The Micro-Scale: Households At The Elk Ridge Site, Southwestern New Mexico, Jared Keith Miles May 2025

Mimbres Social Organization At The Micro-Scale: Households At The Elk Ridge Site, Southwestern New Mexico, Jared Keith Miles

UNLV Theses, Dissertations, Professional Papers, and Capstones

As a component of the ongoing work with the Elk Ridge research project, this thesis utilizes data acquired from previous excavations of the Elk Ridge site and from previous research in the Mimbres Mogollon region to examine how vernacular architecture reflects social organization at the scale of the household. Following Wilk and Rathje (1982) this approach views the household as a fundamental social and economic unit of past societies. Household is defined here as a group occupying a bounded residential space sharing in domestic activities and decision-making responsibilities (Roth 2012:137, Kramer 1982:637, Blanton 1994:5). Previous works within the Mimbres Mogollon …

Looking Back, Looking Forward: Contextualizing Historical Bioarchaeological Accounts With Contemporary Social Issues, Katharine Chiyono Woollen

UNLV Theses, Dissertations, Professional Papers, and Capstones

The very existence of women has been taken for granted throughout history. Their domestic roles are viewed as biologically fixed, resulting in a general lack of information recorded or researched relating to their lived experiences, life histories, and narratives. Instead, it is the history of white men that has been standardized as the norm, creating visible gaps in our understanding of women’s experiences. Additionally, the majority of existing literature centers on female reproduction, their roles as mothers, and violence enacted against women. While this information contributes towards a greater understanding of women’s experiences in bioarchaeological investigations, these data often lack …

The Lasting Impact Of Belonging: Exploring The Relationship Between Undergraduate Experiences And Black Alumni Contributions, Kauna Greene May 2025

The Lasting Impact Of Belonging: Exploring The Relationship Between Undergraduate Experiences And Black Alumni Contributions, Kauna Greene

Graduate Theses & Dissertations

Black alumni at predominantly white institutions (PWIs) remain underrepresented in alumni engagement and philanthropic research, despite a long and well-documented tradition of Black philanthropy. This qualitative, phenomenological study examines the relationship between undergraduate experiences and the post-graduation engagement of Black alumni from a private PWI in the Mid-Atlantic region of the United States. Guided by Strayhorn's (2019) theory of sense of belonging, the study investigates what motivates Black alumni to contribute financially, non-financially (through mentorship, event attendance, and volunteering), or not at all, and how undergraduate feelings of belonging shape those decisions. Data were collected through an anonymous online survey …


Two-Way Random Effects Model With Serial Correlation, Badi H. Baltagi, Georges Bresson, Jean-Michel Etienne May 2025

Two-Way Random Effects Model With Serial Correlation, Badi H. Baltagi, Georges Bresson, Jean-Michel Etienne

Center for Policy Research

This paper derives a feasible GLS estimator for a two-way error component model with serial correlation on both the time effects as well as the remainder disturbances. This estimator is based on two methods, one proposed by De Porres and Krishnakumar (2013) for deriving the spectral decomposition of a general error component structure and the other based on an inversion trick for the variance-covariance matrix of this model suggested by Skoglund and Karlsson (2001). While the last paper used maximum likelihood methods under the normality assumption, we use method of moments estimators following Baltagi and Li (1991) for the one-way …


Towards The Signed Decomposition Of Young Quasisymmetric Schur Functions Into Dual Immaculate Quasisymmetric Functions, Gavin Butts, Joshua Hallam May 2025

Towards The Signed Decomposition Of Young Quasisymmetric Schur Functions Into Dual Immaculate Quasisymmetric Functions, Gavin Butts, Joshua Hallam

Honors Thesis

We introduce a family of descent-preserving, sign-reversing involutions on encodings of standard immaculate tableaux which, in the two-row case, identifies pairs standard immaculate tableaux, leaving exactly those satisfying the conditions of standard Young composition tableaux fixed. Using this result, we derive the first explicit signed decomposition of the Young quasisymmetric Schur functions into dual immaculate quasisymmetric functions, confirming the conjectured decomposition, by Allen-Hallam-Mason, in the two-row setting. Along the way, considering the number of descent elements, we obtain counted refinements of standard immaculate tableaux and standard Young composition tableaux with shapes (n,n+1) and (n+1, …


Peripheral Neuroimmune Mechanisms Of Chronic Back Pain, Aleyah Esther Goins May 2025

Peripheral Neuroimmune Mechanisms Of Chronic Back Pain, Aleyah Esther Goins

Biomedical Sciences ETDs

Chronic back pain (CBP) affects 1 in 10 people worldwide, reducing mobility, productivity, and quality of life. Despite its prevalence, non-addictive treatments remain limited due to an incomplete understanding of chronic pain mechanisms. This dissertation examines peripheral neuroimmune interactions in CBP using a urokinase-type plasminogen activator (uPA)-induced mouse model (uPA-CBP). uPA, a pro-inflammatory serine protease, was injected into the L2/L3 lumbar spinous ligament, inducing prolonged mechanical and cold hypersensitivity. Flow cytometry of dorsal root ganglia (DRG) showed increased CD45+CD11b+ myeloid cells in males and CD45+CD3+CD4+ lymphocytes in females. DRG neurons from male uPA-CBP mice exhibited heightened action potential firing. Pharmacological …

Sub Terra, Daniel J. Forest May 2025

Sub Terra, Daniel J. Forest

MFA Thesis Exhibit Catalogs

Abstract

Sub Terra is an immersive exhibition that renders intangible states of mind through sculptural installation. These constructions speak to internalized angst and complexity, mirroring what is seldom looked at, witnessed, or acknowledged. Many symbolic elements are suspended from either the walls and ceiling or within constructed frames, evoking entanglement. My work is an attempt to express the emotion turmoil inherent to living in an increasingly bureaucratic society and its effect on someone with an anxiety disorder.

The fabrication entails several broad skill sets, requiring familiarity with psychology, physiology, fine woodworking, ceramics, felting, and drafting. Preliminary sketches guided construction and …


Policy Analysis Of Assessments To Award Seals Of Biliteracy In Spanish In The United States, Lisa J. Harmon-Martínez May 2025

Policy Analysis Of Assessments To Award Seals Of Biliteracy In Spanish In The United States, Lisa J. Harmon-Martínez

Teacher Education, Educational Leadership & Policy ETDs

The Seal of Biliteracy (SoBL) honors high school graduates demonstrating proficiency in two or more languages, yet its policies often perpetuate inequities. Focusing on New Mexico and Spanish language assessments, I explored how the SoBL's recognition of bilingualism intersects with biases against Spanish speakers. While the SoBL aims to celebrate bilingualism, disparities arise from state-to-state variations in assessment requirements, particularly affecting Spanish-speaking students and those receiving English Language Development services. Many states rely on standardized exams that inadequately capture students’ linguistic abilities, exacerbating inequalities. Using an Open Systems policy framework and Translanguaging theory, which values students’ full linguistic repertoires, I …

Balance, Liberty, And Law: Montesquieu’S Legacy In U.S. Constitutional Thought, Christian Yockey May 2025

Balance, Liberty, And Law: Montesquieu’S Legacy In U.S. Constitutional Thought, Christian Yockey

History Student Research

In 1787, a Constitutional Convention was convened to revise the weak Articles of Confederation. However, the delegates at this convention ended up creating an entirely new system of government—that is one with a much more powerful structure of federal power. This paper examines the influence of the French philosopher Baron de Montesquieu on this process and the creation of early U.S. political culture. While previous academic scholarship has acknowledged Montesquieu’s influence on this process of writing the Constitution, this paper seeks to explore further the specific ways his influence shows itself in the U.S. Constitution and the creation of U.S. …


Bell Telephone System’S Preeminent Role In The Growth Of Industrial Design, Ralph O. Meyer, Russell A. Flinchum May 2025

Bell Telephone System’S Preeminent Role In The Growth Of Industrial Design, Ralph O. Meyer, Russell A. Flinchum

Purdue University Press Books

Histories of design pay scant attention to the corded telephone, which played an immeasurable role in early communication. Although the Bell System, with many Nobel Prizes, is justly acknowledged for its technical prowess, it should also be recognized for its early and considerable impact on the developing discipline of industrial design. In 1930, young Henry Dreyfuss, who would later become known as a pioneer of industrial design, was retained by the Bell System as a design consultant and matured in that environment. With substantial input from Bell System engineers, Dreyfuss and his staff produced attractive telephone designs that were manufactured …


Comparison Of Gluteal Muscle Central Activation In Individuals With And Without Patellofemoral Pain, Michael Carpio, John S. Donohue, Jacob P. Kissman May 2025

Comparison Of Gluteal Muscle Central Activation In Individuals With And Without Patellofemoral Pain, Michael Carpio, John S. Donohue, Jacob P. Kissman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose/Hypothesis: Individuals with patellofemoral pain (PFP) often present with knee valgus during weight-bearing activities. Weakness in the gluteal muscles is thought to contribute to this condition, but recent studies suggest that hip weakness might be a secondary problem in this population. Central nervous system adaptations have been noted in persons with PFP, which can lead to altered muscle function, faulty movement patterns, and poor function. Experimentally, central activation can be quantified by a central activation ratio (CAR) via superimposed burst (SIB) during a maximum voluntary isometric contraction (MVIC) where the ratio of volitionally activated motor units to total motor units …


Lower Limb Loss Related Physical Therapy Outcome Measures: A Scoping Review, Cassandra Evergreen, Harrison Hess, Ryan Orton May 2025

Lower Limb Loss Related Physical Therapy Outcome Measures: A Scoping Review, Cassandra Evergreen, Harrison Hess, Ryan Orton

UNLV Theses, Dissertations, Professional Papers, and Capstones

This scoping review aims to explore the use of performance-based outcome measures (PBOMs) and patient-reported outcome measures (PROMs) in assessing the function of individuals with lower limb loss (LLL). The review identified common PBOMs, such as the 6- and 2-minute walk tests, Timed Up and Go (TUG), and Amputee Mobility Predictor (AMP), which evaluate mobility and overall physical function. PROMs, like the Prosthesis Evaluation Questionnaire (PEQ), focus on the prosthetic experience, including comfort, satisfaction, and quality of life. Both PBOMs and PROMs assess patient function, yet with differing emphases; PBOMs primarily evaluate physical performance while PROMs capture broader health attributes, …

The “Asian”-Ness Of Women Influencing The Romance Plot In Contemporary Ya Literature, Janetsa Jane Keovorabouth

UNLV Theses, Dissertations, Professional Papers, and Capstones

Contemporary young adult literature (YAL) is a growing genre that features a diverse range of stories, allowing young readers to see themselves reflected in realistic stories. One of its prominent subgenres, contemporary young adult romance focuses on a modern love story between two individuals. Historically, Asian American female characters were often depicted as the “model minority” stereotype or represented as exoticized figures who held traits such as mysterious, submissive, or seductive creatures. These portrayals often treated the Asian American experience as monolithic. However, the genre now explores an intersection of identity and romance, addressing themes commonly found in contemporary realism …


Clinical Benefit Analysis Of Modified Motion Management Protocols, Dyanne S. Macalinao May 2025

Clinical Benefit Analysis Of Modified Motion Management Protocols, Dyanne S. Macalinao

UNLV Theses, Dissertations, Professional Papers, and Capstones

Radiation therapy is crucial for treating cancer, using ionizing radiation to target and destroy cancer cells. This radiation is produced by machines like linear accelerators or through natural radioactive decay. Radiation therapy treatment planning involves prescribing doses and contouring target areas. However, managing tumors that move with breathing, such as in the lungs, remains a major challenge. Tumor motion exceeding 5 mm, as outlined in the AAPM’s Task Group 76, can compromise treatment accuracy, risking underdosing the tumor and overdosing healthy tissue. This issue is especially critical in high dose treatments like stereotactic body radiation therapy (SBRT). TG-76 provides different …
