The Extraction And Chemical Characterization Of The Avian Pigments Turacin And Turacoverdin, Sarah R. Bekkali

Honors Scholar Theses

Bird coloration is a trait that extends beyond mere aesthetics as it has an extensive range of biological significance. Plumage patterns and hues can influence camouflage, mate choice, social dominance, and physiological performance. Bird fitness, their ability to survive and reproduce, is greatly dependent on color. Melanins, carotenoids, and pterins are well-studied pigment systems that are commonly found across many avian species’. Alternatively, porphyrin-based pigments are rare and less-studied as they only found in turacos a sub-Saharan African bird belonging to the family Musophagidae. This thesis focuses on two pigments of interest: turacin, the deep crimson-red pigment found in …

Saving The Great Basin: Creating Places For The Birds, Bees And Beyond, Carlos Gomez

Hospitality Design Graduate Student Capstones

This project looks at how vacant and underused parcels along the Truckee River in Reno, Nevada, can be rethought as part of a larger ecological system. Rather than treating these parcels as empty leftover spaces, the project sees them as opportunities to create small habitat patches that can support native species, improve stormwater function, and strengthen the river corridor over time. The work focuses on three sites along the Truckee River: California Avenue, Island Avenue, and Commercial Row. Each site responds to a different condition along the urban transect, from a sloped residential river edge to a tighter urban parcel …

Schools Of The Desert: An Integrated Approach To Learning Through Biophilic & Contextual Design, Rejndi Hylviu

Hospitality Design Graduate Student Capstones

This capstone investigates how high school environments in arid regions can be reimagined through the integration of biophilic design, climate-responsive strategies, and place-based learning. Grounded in personal experience growing up in the Southwest, the project begins by identifying a widespread condition of disconnection, where students are educated in environments that are sealed off from the very landscapes they inhabit. Through a synthesis of literature, case studies, and interviews, the research establishes that exposure to natural systems can measurably improve cognitive performance, emotional well-being, physical health, and social behavior. Biophilic principles such as dynamic light, material connection, prospect and refuge, and …

Sunrise To Sunset Walk, Mariana Clara Servin

Hospitality Design Graduate Student Capstones

Sunrise Manor, known as the East Side, is often overlooked and avoided. It carries a negative reputation, with locals frequently advising tourists to stay away, a pattern common in neighborhoods where marginalized communities reside. Despite its vibrancy, the area lacks parks, public amenities, and entertainment, leaving residents underserved. Sunrise Manor is predominantly Hispanic, and its cultural presence is embedded in everyday street life, where vendors sell fruit, food, flowers, and goods on neighborhood corners. This identity has also shaped destinations like Broadacres Marketplace, the largest outdoor swap meet in Las Vegas. However, recent immigration policies and rising fears within the …

The Jezebel stereotype is a racial stereotype with biblical ties that portrays black women as seductive, sexually insatiable beings. The horror genre explores humanity’s biggest fears and anxieties by looking at subgenres such as blaxploitation and vampirism. In this essay, I'll explore the intersectionalities of race, gender, and religion through the portrayal of black female sexuality in the horror genre. In films such as Ganja & Hess (1973), Abby (1976), and Def by Temptation (1990), they all depict the Jezebel stereotype. In an in-depth analysis of these films, I'll go over the ways in which they reinforce the Jezebel stereotype, …

Virus-Like Particle Peptoid Conjugate As A Triple-Negative Breast Cancer Targeting Delivery System, Ricky Zhu

Chemistry Theses

Triple-negative breast cancer (TNBC), an aggressive form of breast cancer, characterized by its lack of estrogen receptors (ER), progesterone receptors (PR), and human epidermal growth factor receptors (HER2) poses a therapeutic challenge as common treatment options are rendered ineffective. Here is a strategy to develop a drug delivery system utilizing poly-glycinated LC129 8, a TNBC targeting peptoid, covalently attached to HK97 virus-like particles (VLP) containing a C-terminal LPETG sequence via a sortase mediated reaction. Using the properties of the cage-like structure of VLPs and the TNBC specificity of the LC129-8, high doses of chemotherapy can be efficiently loaded into the …

Performatic Learning In Informal Education: A Mixed Methods Study Of Zine-Making As A Catalyst For Intentional Epistemic Claiming, Experiential Knowing, And Cultural Mediation In A Museum-Based Learning Environment, April Ursula Fox

UNLV Theses, Dissertations, Professional Papers, and Capstones

Informal learning environments are powerful sites of meaning-making when learners are invited to move from observer to author. This study positions zine-making as an effective educational tool capable of promoting that transformation. The study advances a new framework—Performatic Learning—to articulate how creative, multimodal practices can support learning as becoming. Developed through foundational pilot studies and an in-depth mixed-methods investigation in a natural history museum, the framework integrates five constructs: Intentional Epistemic Claiming, Experiential Knowing, Cultural Mediation, Performatic Space, and Learning as Becoming. Across cases, zine-making emerged as a generative learning space in which participants authored knowledge, navigated uncertainty, drew on …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The detonation of the first atomic bomb in the early morning of July 16, 1945, in New Mexico welcomed the atomic age that forever changed the world. After that day, thousands of lives were lost due to nuclear weapons, and hundreds of thousands more continued to suffer from the effects of atomic testing. The Atomic Energy Commission, fueled by the arms race of the Cold War, chose Nevada to continue the United States’ nuclear weapons testing. Knowledge of the dangers of radiation exposure, the effects of radiation, and techniques to prevent exposure are now available in part due to the …

Junctional Actin As A Mechanical Hub For Supracellular Actomyosin Force Transmission During Apical Constriction, Jasneet Brar

UNLV Theses, Dissertations, Professional Papers, and Capstones

Apical constriction is a conserved morphogenetic mechanism that drives epithelial folding during development. During ventral furrow formation in Drosophila melanogaster, contractile actomyosin networks generate forces that reduce apical cell area resulting in tissue invagination. For these cell-scale forces to produce coordinated tissue-scale changes, contractile networks must be mechanically integrated across neighboring cells. Although adherens junctions are known to mediate this coupling, it is unclear how junctions are integrated into cortical actin cytoskeleton, which directly determines cell, and consequently tissue, shape. This thesis tests the hypothesis that supracellular actomyosin organization during apical constriction depends on distinct adherens junction based mechanical couplings: …

Organizational Justice And Staff Well-Being In Probation And Parole, Deena R. Devore

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study examines how probation and parole (P&P) officers perceive fairness within their organizations and how these perceptions relate to job satisfaction, organizational commitment, and emotional exhaustion. Organizational justice research has been conducted primarily in business and policing contexts, with limited attention to whether established measurement models accurately capture fairness in community corrections. Because P&P officers operate within hybrid roles characterized by discretion, sustained supervisory relationships, and bureaucratic constraint, fairness perceptions in this setting may not align cleanly with existing dimensional frameworks.

Using survey data collected from P&P officers in a western U.S. state, this study evaluates competing measurement structures …

Constructing Imperial Connectivity: State Infrastructure Projects And The Imperial Gaze In Bengal Presidency, 1849-1856, Richard William Bradley Gaspers Iii

UNLV Theses, Dissertations, Professional Papers, and Capstones

The construction of roads, canals, and supporting infrastructure in British India connected urban environs of power to interior peripheral spaces. The conclusion of the Second Anglo-Sikh War in 1849 saw the East India Company stand alone as the paramount power over the Indian subcontinent. A century of conquest gave way to a century of internal management. This shifted the state’s ‘gaze’ inward. Public infrastructure construction skyrocketed after 1849, transforming the role of the colonial state as it built roads, canals, bridges, courthouses, police stations, and jails on an unprecedented scale. This thesis will explore how these physical constructs bolstered connectivity, …

A Tale Of Two Mammals: Tenrec Ecaudatus And Homo Sapiens, Debra Renee Kerr

UNLV Theses, Dissertations, Professional Papers, and Capstones

Most modern mammals maintain stable body temperatures (Tb) ~37ºC and high metabolic rates. Hibernators, like ground squirrels, are homeothermic during the active summer season, but are heterothermic during the hibernation season. During the hibernation season, ground squirrels follow a predictable pattern of torpor bouts interrupted by interbout arousals. Tenrecs are unusual because they are heterothermic and heterometabolic even during the active season. Previously, ground squirrel bile constituents were shown to be predictive of whether a squirrel is in the summer active or winter hibernation season. We found tenrec bile constituents were highly variable and not predictive of seasonal and metabolic …

Prepulse Inhibition And Emotion: A Systematic Review, Jennifer U. Le

UNLV Theses, Dissertations, Professional Papers, and Capstones

Prepulse inhibition is a neurological pre-conscious sensorimotor gating mechanism by which a softer auditory sound (or prepulse) preceding a startle probe (or pulse) and subsequently reduce the magnitude of the startle blink reflex. Prepulse inhibition is deficient in many psychological disorders where emotion is a central component; however, emotion has been scarcely examined with prepulse inhibition in human studies. The current study is a systematic review that examines three databases (APA PSYCInfo, Pub Med, and CINAHL) to examine how state and trait emotion (such as happiness, sadness, anger, disgust) is related to prepulse inhibition within human subjects. The initial search …

Protest Policing And Legitimacy: A Comparative Analysis Of Myanmar And The United States, Khaing Sandee Lynn

UNLV Theses, Dissertations, Professional Papers, and Capstones

Political protests garner immense attention during academic, socio-political, and policy discourse discussions. More specifically, the manner in which government, police, and protestors interact during protest events is heavily observed and debated. Research shows that legitimacy is established when power-holders act in accordance with legal frameworks and various political and institutional norms. With focus on the intersection of legitimacy and protest policing, the current study aims to explore how political, legal, and institutional legitimacy influence police compliance with state and institutional directives, and protestor compliance with police directives in two distinct sociopolitical contexts.

For this purpose, qualitative data was collected through …

Methylation-Dependent Regulatory Pathway That Governs The Stability Of The Sox Family Proteins And Related Developmental Regulators, Keshari Gayathri Rajawasam

UNLV Theses, Dissertations, Professional Papers, and Capstones

The SRY (Sex-determining Region Y) protein is a transcription factor encoded on the Y chromosome and is the key regulator responsible for initiating male sex determination in mammals. During early embryonic development, SRY activates the genetic program that leads to testis formation by promoting the expression of downstream genes involved in male gonadal differentiation. Mutations or dysregulation of SRY can lead to disorders of sex development such as male-to-female sex conversion and hermaphroditism, highlighting its critical role in sex determination.

SRY belongs to the SOX (SRY-related HMG-box) family of transcription factors, which includes the proteins SOX1, SOX2 and SOX3. These …

Is Forgetting Independent Of Learning? An Examination Of Initial Learning Across Alternative Forgetting Analyses, Rhiannon Nicole Soriano Smith

UNLV Theses, Dissertations, Professional Papers, and Capstones

A long-standing debate has reappeared regarding whether the rate of forgetting is independent or dependent upon the initial degree of learning. Interestingly, both conclusions have been supported. These diverging conclusions could be due to the analytical method and operational definition of forgetting employed: Researchers supporting independence typically measure forgetting as the number of items forgotten at a given retention interval, while those in favor of dependence typically measure forgetting as the number of items forgotten between test intervals. The current study tested whether the degree of learning affects the rate of forgetting for recognition accuracy (da) and other memory processes …

Exploring Non-Native English Learners’ Attitudes Towards Ai And Online Multimedia Persuasive Opinions And The Role Of Sentiment, Zvetomira N. Svetleff

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study and various other studies use quantitative models to identify which persuasive features predict persuasiveness. Most studies in the field do not explain why participants responded as they did nor do they focus on studying adult non-native English learners also referred to as second language (L2) English learners. Despite seemingly remarkable progress on research related to how to convey persuasive messages, there has been little work related to persuasive messaging targeted at second language learners or non-native speakers. In addition, despite the increasing reliance on AI technologies and tools in language learning within educational and work settings, there has …

Acoustic To Electronic: Multidimensional Musical Explorations, Kanenar Wen

Student Theses

The music of the film was once thought to affect the emotions of the audience without their knowledge (Gorbman, 1987). But in some new partnerships on film projects from students, the lines between music, sound, and silence should be erased. Music could be more of a texture. The sound effects may also have the characteristics of the music. Silence could communicate information. In the usual definition of music, it highlights the phrases, timbre, and harmonic composition. When it is altered, the sound is not only “music,” but it is also in combination with the image, time, and narrative; it becomes …

Modernidad, Heterogeneidad Y Utopía En Todas Las Sangres De José María Arguedas, Matthew J. Adams Jr

Spanish Honors Papers

This project analyzes José María Arguedas’s novel Todas las sangres (1964), focusing on the sociological and utopian dimensions that were explicitly questioned during the roundtable discussion on the novel held at the Instituto de Estudios Peruanos (IEP) on June 23, 1965. In that forum, participants offered pointed critiques of the plausibility of the social reality represented in Arguedas’s narrative. Moving beyond these objections, I argue that the literary reality Arguedas constructs—through what Antonio Cornejo-Polar has conceptualized as the “choral novel”—captures the enduring force of the colonial legacy and the historically and culturally heterogeneous condition of Peruvian society, dimensions that the …
