Development And Initial Validation Of The Veterans Educational Transition Scale (Vets): A Brief Scale To Predict Successful Transition Of Student Veterans To College, Lisa Beckman
UNLV Theses, Dissertations, Professional Papers, and Capstones
The aim of this dissertation was to develop and validate a scale to assess factors that interfere with veterans’ successful transition from military life to the college environment. Student veterans are a unique population in the student body and often have unique challenges assimilating to the college environment, including difficulties making social connections, multiple life responsibilities, and unique mental health presentations. Currently, there is no measure to assess and identify transition challenges that student veterans may experience, and yet significantly more veterans are enrolling in college to take advantage of their post-9/11 GI bill benefits. This dissertation includes two studies. …
Middle Powers, Capital Subscriptions, And The Inter-American Development Bank, Aaron Coates
Middle Powers, Capital Subscriptions, And The Inter-American Development Bank, Aaron Coates
UNLV Theses, Dissertations, Professional Papers, and Capstones
Using liberal theory, this dissertation examines the behavior of member states in the Inter-American Development Bank (IADB), with a focus on middle powers. In particular, I analyze whether trade between middle powers and Latin America and the Caribbean is associated with an increase in middle powers’ subscription shares in the IADB. The analysis draws on a cross-sectional time-series data set of capital subscription shares (in log form, and first-differenced) for the period of 2004 to 2018. The results suggest that among all members of the IADB, an increase in members’ trade with Latin America and the Caribbean was associated with …
Rusalka And The Snow Maiden: A Comparative Study Of Two Fairytale Operas, Olivera Gjorgoska
Rusalka And The Snow Maiden: A Comparative Study Of Two Fairytale Operas, Olivera Gjorgoska
UNLV Theses, Dissertations, Professional Papers, and Capstones
The two late-romantic operas Rusalka by Antonín Dvořák and The Snow Maiden by Nikolai Rimsky-Korsakov are based on fairy tales, and combine romance, fantasy, and drama. Their plots develop in parallel universes and have astonishing similarities. However, the music and drama develop following different goals. In Rusalka, leitmotifs and dramatic harmonies shape the plot into a tragedy. In The Snow Maiden motives and melodies exist to describe the character rather than lead the story and the drama; the focus is on Russian folk elements, choruses, and people.
The main character in both operas is a naïve, beautiful, fairy-like female character …
Tissue-Specific Responses From A Global Developmental Signal: A Detailed Subcellular Analysis Of The 20e And Rab Signaling Pathways Controlling Exocrine Secretion During Drosophila Development, Nichalas Nelson
UNLV Theses, Dissertations, Professional Papers, and Capstones
During metamorphosis, the steroid hormone 20-hydroxecydysone (20E) triggers a plethora of tissue-specific responses in the common fruit fly, Drosophila melanogaster. The salivary glands are exocrine organs that respond to a large pulse of 20E to secrete a massive cargo of stored glycoproteins called glue. Because the glands are amenable to ex vivo-organ culture and powerful genetic manipulations, they are an excellent model for studying the conserved developmental and physiological signaling pathways that regulate the general function of these specialized secretory tissues. Our lab has generated transgenic animals in which the secreted glue molecules are tagged with fluorescent proteins. I have …
Perceptions Of The Built Environment Among Older Adults Who Live In Age-Restricted Communities Compared To Those Who Do Not In Southern Nevada, Sandra Annan
UNLV Theses, Dissertations, Professional Papers, and Capstones
As Americans are living longer, there has been exponential growth in the number of older adults. Growth in the aging population has created unique challenges. As seniors age, they face many changes in their health, financial stability, and lifestyle, making it challenging to remain independent. The inability to remain independent can be a stressful and depressing experience for older adults. Studies show that most seniors prefer to stay in their current living environment as they age, or age in place, rather than move into senior housing or other available housing options designed for aging. This study investigates how perceptions about …

Understanding The Professional Experiences Of White Jewish Women In Higher Education: An Intrinsic Case Study Analysis, Janna M. Bernstein
UNLV Theses, Dissertations, Professional Papers, and Capstones
The exploration of female professionals’ experiences within the realm of higher education is steadily increasing, yet researchers have yet to analyze, much less include, Jewish women. Following a qualitative intrinsic case study approach, this study assesses the lived experiences of ten white Jewish women professionals to better understand how they engage in the world of higher education differently than their non-Jewish counterparts. Using racial formation theory and intersectional analysis as theoretical frameworks, the research examined the current and historical literature on Jewish identity, the role of Jews and Jewish women in higher education, and the relevant methodological research. The study …

Analysis Of High-Speed Rail Operations Using Vissim Simulation To Determine Access Charges And The Impact Of Incidents On A Shared Network, Komal Sree Teja Boyapati
UNLV Theses, Dissertations, Professional Papers, and Capstones
Shared High-Speed Rail (HSR) networks are networks where two or more railway operators use the same railway network infrastructure for train operations. The train operations in the shared HSR network can be composed of different types of trains operating at different speeds with varying stops at stations in a network. The interactions between different types of trains in the shared HSR network depends on the characteristics of the network’s infrastructure and train operations, and affect the capacity of the network. When a rail operator who owns the infrastructure allows other operators to access its infrastructure, the additional traffic will lead …

Validation Of Novel Obstructive Sleep Apnea Treatment With Silicone Gel Experimental Models, Dustin Walter Burd
Validation Of Novel Obstructive Sleep Apnea Treatment With Silicone Gel Experimental Models, Dustin Walter Burd
UNLV Theses, Dissertations, Professional Papers, and Capstones
Predictive modeling to increase treatment success rates for surgical procedures is becoming more common in the scientific community. For obstructive sleep apnea (OSA), modeling has been predominately performed using computers as opposed to experimental models. Computer simulation saves time by eliminating the need to fabricate complex experimental models but comes at the expense of insight gained through physical observations made in real time. Experimental models for studying OSA are needed to validate computational work, provide perspective on anatomical scale and demonstrate complex deformations in real time. This work addresses prior hurdles in experimental model fabrication with a novel process using …
The Economy Of (Dis)Honor In The Americas: A Transnational Rupturing Of American Literature Through Faulkner, García Márquez, And Silko, Clayton Neil Cobb
The Economy Of (Dis)Honor In The Americas: A Transnational Rupturing Of American Literature Through Faulkner, García Márquez, And Silko, Clayton Neil Cobb
UNLV Theses, Dissertations, Professional Papers, and Capstones
Honor is misunderstood within popular culture, but it is also misunderstood within academic contexts. This is due to a decoupling of the term from its long historical significance, a significance that must not be ignored. That is because honor in the Americas is a structure of the hemisphere’s colonial legacy, its manifestation in the cultural fabric a result of the invasion of the continents by European settlers and colonizers. In the case of history, philosophy, and social science, the study of honor is beginning to undergo appropriate theorization to recognize that legacy; however, within literary studies disciplines, critical understanding of …

The Effect Of Body Armor On Pulmonary Function And Repeated Sprint Performance, Dustin Dunnick
The Effect Of Body Armor On Pulmonary Function And Repeated Sprint Performance, Dustin Dunnick
UNLV Theses, Dissertations, Professional Papers, and Capstones
Introduction: Tactical athletes face the unique task of performing physically demanding occupational duties often while wearing torso-borne loads. While pulmonary function has been shown to decrease while wearing plate-carrier style body armor, there has yet to be a study using the more accurate measurement of plethysmography to determine exactly why. Additionally, the inspiratory muscle’s pressure generation capabilities and how they respond to a repeated running sprint test while wearing body armor are unknown. Therefore, the purpose of this dissertation was to examine how body armor affects pulmonary function, inspiratory muscle strength, and athletic performance during repeated, high-intensity sprints.
Methods: Twelve …

Vibration Overtone Hyperpolarizability Measured For H2 Using Electric Field Induced Second Harmonic Generation, Rachel Ellis
UNLV Theses, Dissertations, Professional Papers, and Capstones
The vibrational contribution to the second hyperpolarizability (γ) of gas phase H2 was measured using electric field induced second harmonic generation. Measurements were made for the pure vibrational 3-0 Q(J) overtone transitions (v=0,J → v’=3,J for J = 0,1,2,3). Measured intensities were found to be 4-14% larger than ab initio calculations. The first chapter of this thesis provides an introduction to nonlinear optics, second harmonic generation, and the tensor nature of hyperpolarizabilities. The second chapter provides theoretical expressions for γ and relevant static and Raman polarizabilities. The third chapter covers the experimental design and electric field induced second harmonic generation. …

Light Conditions During Desiccation And Rehydration Impact The Recovery Of Cultured Timmiella Crassinervis, Sotodeh Ebrahimi
UNLV Theses, Dissertations, Professional Papers, and Capstones
Many terrestrial mosses of xeric environments experience excess light during extended periods of desiccation. While dry or hydrated, excess light energy can lead to formation of reactive oxygen species and photoinhibition (e.g. damage to Photosystem II) which affects photosynthetic stress and efficiency. This study aimed to determine the effect of duration dry and light intensity (PAR) on cultured shoots of the chaparral moss Timmiella crassinervis, as well as to elucidate the optimal rehydration light conditions for this species. I hypothesized that 1) mosses exposed to higher light intensities during desiccation would incur more damage upon rehydration than those exposed to …

A Divide And Conquer With Semi-Global Failover For Software Defined Networks, Kasra Goravanchi
UNLV Theses, Dissertations, Professional Papers, and Capstones
Nowadays, many service providers need to provide many other functions than just a network connectivity. They also need to provide network functions such as network address translation, firewall, encryption, Domain Name Service (DNS), caching, routing and many other services. Usually these functions come with the hardware at the user or customer’s premises. This can increase the revenue of the revenue, but also can cost a lot and also be extremely difficult to maintain. Moreover, it is important to be able to configure the network and later modify the configuration to create fault tolerance and to prepare the system for future …

Validity And Diagnostic Accuracy Of An Adhd Symptom Rating Scale For Identifying Adults With Adhd, Stacy Jean Graves
UNLV Theses, Dissertations, Professional Papers, and Capstones
Specific rating scales of ADHD symptomatology are often included in neuropsychological assessments evaluating adults diagnosed with Attention Deficit Hyperactivity Disorder (ADHD). The Barkley Adult ADHD Rating Scale-IV (BAARS-IV) is a widely used symptom rating scale that includes four questionnaires: self-report current, self-report childhood, other-report current, and other-report childhood. In addition to ADHD symptoms, each of the forms include items that assess functional impact and developmental history of symptomatology. While similar symptom rating scales have been found to have high validity and diagnostic utility in children, it is unclear the extent to which the BAARS-IV shares substantial common variance with other …

Tectonic Evolution Of The Tucki Mountain Metamorphic Core Complex, Southeastern California: Evidence For Late Cretaceous Extension Within The Sevier-Laramide Orogen, William Killey Barba
UNLV Theses, Dissertations, Professional Papers, and Capstones
The exhumation of Cordilleran metamorphic core complexes from mid-crustal depths in the western U.S. Basin and Range Province has been classically associated with Cenozoic extension. However, recent studies reveal that extensional tectonic exhumation of numerous metamorphic core complexes initiated during the Late Cretaceous. New geologic mapping and structural analysis integrated with geochronology and thermochronology data provide evidence for a Late Cretaceous extensional shear zone, previously interpreted as Miocene in age, within the Tucki Mountain metamorphic core complex on the western flank of Death Valley, California. The shear zone occurs within the immediate footwall of the Miocene-Pliocene Tucki Mountain detachment fault …

Addressing Disproportionality In School Discipline Through Alternatives To Exclusionary Discipline Practices, Kevin Matthew Higley
Addressing Disproportionality In School Discipline Through Alternatives To Exclusionary Discipline Practices, Kevin Matthew Higley
UNLV Theses, Dissertations, Professional Papers, and Capstones
Tasked with ensuring that school environments are safe and orderly, school administrators spend an increasingly inordinate amount of time and energy on managing student discipline. Often, when students commit egregious behaviors or violate school policy, schools resort to out-of-school disciplinary consequences, i.e. suspension, expulsion, or alternative educational placements, in attempts to reduce problem behaviors from recurring. Historically though, these exclusionary discipline practices have led to the unfair treatment of some students, (e.g., Black/African American students, male students, and/or students with disabilities). This disproportionate practice is often cited as the genesis for the school-to prison pipeline phenomenon. From a behaviorist perspective, …

Fast Neutron Assay Of Elemental Content Of Bulk Samples, Calder Emerson Lane
UNLV Theses, Dissertations, Professional Papers, and Capstones
The purpose of this research was to analyze the capabilities of fast neutrons in the detection and analysis of various isotopes in bulk samples. The deuterium-tritium (DT) fusion reaction generates highly penetrating, high-energy (14.1-MeV) neutrons which induce nuclear reactions in irradiated targets. Neutrons and gamma rays are generated in these reactions. Emitted gamma rays are characteristic of the emitter; the gamma spectrum enables stoichiometric identification of the assayed samples. Neutron backscattering can also be used for identification of the elemental composition of the sample.
This work had three objectives. The first objective was to develop a computational technique to model …
The Relationship Among Sociocultural Assimilation, Dietary Behavior, And Physical Activity In Adult Latinxs In The U.S., Erick Lopez
UNLV Theses, Dissertations, Professional Papers, and Capstones
This dissertation examines the relationship between sociocultural assimilation and health behaviors among adult Latinxs in the United States to address whether different assimilation models promote or hinder Latinx health. Existing research on assimilation and health behaviors among Latinxs relies heavily on the use of proxy measures of assimilation such as length of time in the U.S., nativity, age of arrival, and language preferences for surveys. These studies tend to show that greater assimilation to mainstream U.S. culture among Latinxs is associated with the adoption of poor health behaviors and the erosion of the immigrant health advantage. Research that uses sociocultural …

Impact Of Disadvantaged Business Enterprises Participation And Mobilization Cost On Highway Project Performance, Shristy Maharjan
UNLV Theses, Dissertations, Professional Papers, and Capstones
Construction practitioners have their goals to complete projects within time without exceeding the allocated budget. However, studies have shown many projects overrun their allocated budget and face delays due to numerous reasons. Some of the main reasons are lack of efficient construction and financial resource management, lack of proper planning, and unavailability of new construction technologies, as well as ineffective supervision and communication, design changes, and unskilled workers. In some studies, mobilization costs, along with the participation of Disadvantaged Business Enterprises (DBEs) in projects were identified as factors affecting the cost and schedule performance of construction projects. However, no statistical …

A Fortified Extension Of The Aes And Its Implementation, Ashby Mullin
A Fortified Extension Of The Aes And Its Implementation, Ashby Mullin
UNLV Theses, Dissertations, Professional Papers, and Capstones
With the advancement of quantum computing (QC), the integrity of cryptography has been called into question. For example, two QC algorithms have been developed that can break asymmetric encryption (i.e., Grover’s, Shor’s), which also poses a threat to symmetric encryption. Asymmetric encryption efforts addressing this threat include lattice-based cryptography, which uses lattice problems to reduce efficiency of cryptanalysis. Symmetric encryption security can be bolstered by increasing the key length, allowing for additional permutations a key could have; known as keyspace. This thesis seeks to expand the keyspace of symmetric encryption in order to create more possibilities. This fortification to the …

Synthesis, X-Ray Absorption, And X-Ray Diffraction Spectroscopy Studies Of Uranium Based Heavy Fermion Systems, Vahe Mkrtchyan
UNLV Theses, Dissertations, Professional Papers, and Capstones
Heavy fermion systems have attracted a great deal of interest since the discovery of the phenomenon in the 1970s. Over the past 35 years, the research in this field revealed a variety of unprecedented properties that the conventional theoretical framework considered conflicting or impossible. The subset of intermetallic compounds containing rare earth and actinide elements is of special interest, as these materials exhibit a range of exotic properties associated with 4f or 5f electrons. A thorough examination of the reports in the literature indicates a delicate interplay between the competing ground states, giving rise to anomalous properties including non-Fermi liquid …
Constraining Viscous Protoplanetary Disk Models Using Alma Kinematic Observations, Ian Rabago
Constraining Viscous Protoplanetary Disk Models Using Alma Kinematic Observations, Ian Rabago
UNLV Theses, Dissertations, Professional Papers, and Capstones
Recent molecular line observations by ALMA have revealed the 3D velocity structure of protoplanetary disks, providing new insight on the mechanisms of disk accretion and ring/gap formation. Although the constant α viscous disk model has been widely used to describe the disk surface density evolution, it may not adequately describe the gas velocity at different disk heights. By carrying out viscous hydrodynamic simulations, we confirm that the vertical velocity structure varies considerably between these models. On the other hand, the surface density evolution of the disk is only dependent on the vertically integrated stress, and does not depend on a …
