Thinking About Thinking: Children’S Awareness And Development Of Metacognitive Emotion Regulation, Reilly Rowland

UNLV Theses, Dissertations, Professional Papers, and Capstones

Metacognitive emotion regulation is a complex system of our underlying thinking that contributes to the emotions that we endure. By gaining an understanding of this concept, young children can learn various strategies, e.g. cognitive reappraisal, problem solving, and delayed gratification, to help alter their thoughts and/or goals to alleviate negative emotion. Thus, they are able to increase their confidence in their own metacognitive emotion regulation abilities and awareness. This study explored the awareness of young children and their metacognitive emotion regulation abilities, the strategies that young children take part in to try and control negative emotion, and the learning strategies …

Effects Of Wildfire On Plant And Insect Pollinator Communities In The Mojave Desert, Nha Trang Vivian Sam

UNLV Theses, Dissertations, Professional Papers, and Capstones

The changing fire regime of landscapes across the Mojave Desert has prompted considerable research on its effects on plant community recovery, but it has not been widely studied what effects wildfire may have on native pollinators and the vital ecosystem services they provide. Ecological changes from increased wildfire severity from invasive exotic annual grasses will likely continue influencing pollinator habitats and floral resources. Understanding the effects that wildfires have on pollinators is valuable to make decisions as to whether active management and restoration activities are required to conserve ecologically vital pollinator functions. The intention of this thesis was to examine …

Fluctuating Cohesion: A Grounded Theory Study Of Nursing Students Engaged In A Hybrid Debriefing Format, Carol Lynn Senette

UNLV Theses, Dissertations, Professional Papers, and Capstones

Debriefing is a key component of simulation that promotes development of students’ reflective processes. Instructor-led debriefing (ILD) is considered the gold standard; however, research conducted over the past decade demonstrates the negative effects of anxiety on student reflection during ILD. Nursing students’ experiences with ILDs have been substantially investigated; yet scant research explores students’ perceptions and experiences of more learner-centered debriefing formats that deemphasize the instructor role.

The purpose of this grounded theory study was to explore undergraduate nursing students’ perceptions and experiences of a hybrid debriefing format consisting of peer-led debriefing followed immediately by ILD. Specifically, I aimed to …

An array of 63 current comparators feed digital logic gates, via “thermometer code,” that produce a 6-bit output word that is driven off-chip by appropriate buffers.The circuit was designed using Cadence Virtuoso design software. Simulated Differential Non-Linearity (DNL), with an 8µA reference current, is 1.656 LSB at the worst transition involving a scale change. Excluding scale …

The Transformation Of Edgar Huntly: An American Awakening, Willie C. Sosa

UNLV Theses, Dissertations, Professional Papers, and Capstones

Since Charles Brockden Brown published his first novels in the late eighteenth century, he has subsequently shifted back and forth, in importance, from the center to the periphery of the American literary canon. In recent years however, a dramatic increase in scholarship on Brown shows his significance is once again trending back toward the center of importance in this field. Scholarship has tended to coalesce around four topics which can be categorized as postcolonial expansion, the wild city, the distinction between the city and wildness, and identity. Looking closely at identity, although the discourse has done a thorough job of …

Exploring The Lived Experience Of Early-Career Millennial Nursing Faculty: Deriving Meaning From Their Perspective, Adrian Stamps

UNLV Theses, Dissertations, Professional Papers, and Capstones

An innovative way to combat the protracted nursing faculty shortage is to recruit up and coming generations of nurses to academia. The most recent generation to enter the academic ranks are millennials, often categorized in nursing by a birth year between 1981 and 2000. In contrast to preceding generations, millennials are seeking roles in academia earlier in their careers. Research has shown millennials have unique perspectives on the workplace and a tendency to leave positions if they are not satisfied. This pattern could pose a challenge for sustaining the nursing faculty workforce.

How millennials perceive their initial years in the …

Becoming Myself: A Constructivist Grounded Theory Study Of The Gender Transition Experiences Of Practicing Nurses, Rhiannon Dawn Sullivan

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to construct a substantive grounded theory specific to the gender transition experiences of practicing nurses in their personal and professional lives and to explore the barriers and facilitative factors to gender transition for practicing nurses. There has been research regarding transgender individuals’ discrimination experiences in their daily lives related to their gender identity. These negative experiences increase their vulnerability to negative health outcomes, such as anxiety, substance abuse and depression. However, there is very little known about practicing nurses who are transgender. This research is important because the mental and physical health of nurses …

The Processj C++ Runtime System And Code Generator, Alexander Christian Thomason

UNLV Theses, Dissertations, Professional Papers, and Capstones

ProcessJ is a modern Process-Oriented language that builds on previous work from other languages like occam and occam-pi. However, the only readily-available runtime system is built on top of the Java Virtual Machine (JVM). This is not a choice made intentionally, but simply out of a lack of other implementations -- until now. This thesis introduces the new C++-based runtime system for ProcessJ, coupled with a new C++ code generator for the ProcessJ compiler. This thesis later examines the implementation details of the runtime system, including the components that make it up. We also examine the ability to cooperatively schedule …

Microbe-Mineral Interactions During Exceptional Fossil Preservation, Stromatolite Formation, And Desert Varnish Growth, Michael Strange

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Ediacaran to Cambrian Deep Spring Formation consists of mixed carbonate-siliciclastic strata which contain an increasingly complex and biogeographically important biota. Past investigations of the Deep Spring Formation at Mt. Dunfee, Nevada, explored the highly diverse microbialite reefs consisting of a wide range of stromatolite morphologies which exerted significant control on local sedimentation and topography. Early investigations also documented the biomineralizing metazoan Cloudina (an Ediacaran index fossil). However, recent exploration of the area has resulted in the discovery of several new metazoan fossil communities consisting of a diverse assemblage of Ediacaran soft-tissue tubicolous vermiforms (tube fossils) similar to Cloudina. The …

Developing The Young Dramatic Soprano Voice Ages 15-22, Monica Ariane Williams

UNLV Theses, Dissertations, Professional Papers, and Capstones

This doctoral dissertation provides information on how to develop the young dramatic soprano, specifically through more concentrated focus on the breath. Proper breathing is considered the single most important skill a singer will learn, but its methodology continues to mystify multitudes of singers and voice teachers. Voice professionals often write treatises with a chapter or two devoted to breathing, whose explanations are extremely varied, complex or vague. Young dramatic sopranos, whose voices are unwieldy and take longer to develop are at a particular disadvantage for absorbing a solid vocal technique. First, a description, classification and brief history of the young …

Equivalences Of Determinacy Between Levels Of The Borel Hierarchy And Long Games, And Some Generalizations, Katherine Aimee Yost

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis will be primarily focused on directly proving that the determinacy of Borel games in X^ω is equivalent to the determinacy of certain long open games, from a fragment of ZFC that’s well-known to be insufficient to prove Borel determinacy. The main theorem is a level by level result which shows the equivalence between determinacy of open games in a long tree, [Υ^α], and determinacy of Σ_0^α games in X^ω. In Chapter 9, we mimic the proof used in our main theorem to show that the determinacy of clopen games in the product space X^ω × ω^ω is equivalent …

Developments Of Machine Learning Potentials For Atomistic Simulations, Howard Yanxon

UNLV Theses, Dissertations, Professional Papers, and Capstones

Atomistic modeling methods such as molecular dynamics play important roles in investigating time-dependent physical and chemical processes at the microscopic level. In the simulations, energy and forces, sometimes including stress tensor, need to be recalculated iteratively as the atomic configuration evolves. Consequently, atomistic simulations crucially depend on the accuracy of the underlying potential energy surface. Modern quantum mechanical modeling based on density functional theory can consistently generate an accurate description of the potential energy surface. In most cases, molecular dynamics simulations based on density functional theory suffer from highly demanding computational costs. On the other hand, atomistic simulations based on …

Implicit Attitudes, Explicit Attitudes, And Priming: A Preliminary Analysis Of Factors Affecting Use Of Force Decisions, Christopher Allen Forepaugh

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study examines the effects of priming, situational factors, and attitudes on deadly force decision making. A small sample of undergraduates completed high-fidelity deadly force simulations. Simulation results were compared across experimental conditions and various attitudinal and demographic factors. Participants were generally accurate when assessing the threat posed by suspects. Participants primed to expect a threat were more accurate in their decisions but were no more likely to shoot an unarmed suspect. Participants were more accurate when responding to unarmed suspects. Participants more likely to exhibit implicit bias were less accurate. Several attitudinal and demographic traits were associated with deadly …

Resisting ‘Raid-And-Rescue’: Capturing The Ideograph Of Victimhood In Nevada Law A.B. 166, Samantha Thies

UNLV Theses, Dissertations, Professional Papers, and Capstones

Critical rhetoricians and legal communication studies scholars have long recognized that rhetoric and ideology are inherent to legal structures, shaping legislation and impacting the lives of those such laws are meant to address. Fewer look to, not just civic discourses, but also the vernacular discourse surrounding such institutions, shaping the ideologies that support it. There is a need, however, for the study of outlaw discourses to both help define ideographs and challenge their very existence through contrasting outlaw and hegemonic logics. Thus, this thesis examines debates over A.B. 166, a Nevada state law meant to alleviate sex trafficking, by establishing …

An Investigation Into Multi-View Error Correcting Output Code Classifiers Applied To Organ Tissue Classification, Daniel Alvarez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Large amounts of data is being generated constantly each day, so much data that it is difficult to find patterns in order to predict outcomes and make decisions for both humans and machines alike. It would be useful if this data could be simplified using machine learning techniques. For example, biological cell identity is dependent on many factors tied to genetic processes. Such factors include proteins, gene transcription, and gene methylation. Each of these factors are highly complex mechanism with immense amounts of data. Simplifying these can then be helpful in finding patterns in them. Error-Correcting Output Codes (ECOC) does …

UNLV Theses, Dissertations, Professional Papers, and Capstones

Music concerts and festivals draw millions of attendees in the United States and internationally annually. Half of the U.S. population goes to live music events each year, with 33% going to concerts and 18% going to festivals (Nielsen Music 360, 2017). Despite the fact that these events provide security for the safety of both performers and attendees, the context of these events may facilitate various forms of sexual violence. Research has revealed high levels of harassment, groping, and other forms of unwanted sexual behavior at music festivals and concerts. The current study will utilize a national survey to examine unwanted …

Transcriptional Control Of Virulence Genes In The Bacterial Pathogen Shigella Flexneri, Joy Asami Mckenna

UNLV Theses, Dissertations, Professional Papers, and Capstones

Shigella species, the causal agents of bacillary dysentery, use a type III secretion system (T3SS) to inject two waves of virulence proteins, known as effectors, into the human colonic epithelium to subvert host cell machinery. Transcriptional regulation of these virulence genes is controlled by the three-tiered VirF/VirB/MxiE signaling cascade. Of these, VirB has the largest regulon (~50 genes); however, VirB regulatory properties are poorly understood. To date, VirB is known to function to counter or 'anti-silence' transcriptional silencing mediated by the histone-like nucleoid structuring protein H-NS. To better understand VirB regulation, my colleagues and I chose to better define the …

High Pressure Synchrotron Xrd, Nfs, And Nrixs Studies Of Fesb2, Melanie Alden White

UNLV Theses, Dissertations, Professional Papers, and Capstones

This work combines high pressure synchrotron X-ray diffraction (XRD), nuclear forward scattering (NFS), and nuclear resonant inelastic X-ray scattering (NRIXS) experiments on iron diantimonide (FeSb2), a promising thermoelectric material. NRIXS uses the interaction between excited nuclear and lattice states to directly measure the phonon density of states (PDOS) for samples containing certain Mössbauer isotopes. For our experiments, we synthesized FeSb2 enriched with the isotope 57Fe and measured the partial PDOS for 57Fe sites in the FeSb2 lattice. NFS, also known as synchrotron Mössbauer spectroscopy, is a sister technique to NRIXS that studies the hyperfine structure of the excited Mössbauer nuclei. …

Using Novel Mouse Knockout Models To Study The Roles Of Asm (Acid Sphingomyelinase) In The Regulation Of Multiple Stem Cell Compartments In Vivo, Amro Abdalla

UNLV Theses, Dissertations, Professional Papers, and Capstones

Acid Sphingomyelinase (ASM) is a lipid-modifying enzyme that breaks down sphingomyelin lipids into ceramide and phosphorylcholine. Genetic mutations in the human ASM gene leads to Niemann pick diseases (NPD) type A & B. In NPD type A, patients die between 1-2 years old due to severe neurological complications, while NPD type B patients live to adulthood but suffer from severe visceral organ complications. Type A is usually associated with complete inactivation of the ASM gene. The hallmark of NPD is Purkinje neuron (PN) death. PNs, the major neurons in the cerebellum part of the brain, regulate the balance and fine …

UNLV Theses, Dissertations, Professional Papers, and Capstones

With recurring changes in the society, in terms of economy and technology, companies need to ensure that their human capital is aligned with these transformations in order to sustain in a competitive industry. To date, organizations view training as a requirement to increase their employees’ efficiencies and productivity, and reduce their attrition rates. Despite investment in employee training, research shows a lack of transfer of learning to job and as a result minimal return on investment. This issue is due to many barriers, but can be addressed by learning professionals. Poor learning design and training evaluation practices have been identified …

Identifying School Climate Predictors Of School Absenteeism, Victoria Bacon

UNLV Theses, Dissertations, Professional Papers, and Capstones

Attendance is a crucial component of the education system and may be addressed utilizing Multi-Tiered System of Supports (MTSS) models. To effectively utilize such models, clear demarcations between tiers must exist to classify students appropriately. Additionally, relevant risk and protective factors must be identified as targets for intervention and prevention efforts at each tier. Little research exists that identifies school climate factors, and other student-based contextual factors such as academic mindset and social emotional learning, that impact absenteeism. The present study aimed to identify suitable tier demarcations as well as school climate and student-based contextual factors relevant at each tier. …
