A Regime Switching Model For The Term Structure Of Credit Risk Spreads, Seungmook Choi, Michael D. Marcozzi

Mathematical Sciences Faculty Research

We consider a rating-based model for the term structure of credit risk spreads wherein the credit worthiness of the issuer is represented as a finite-state continuous time Markov process. This approach entails a progressive drift in creditquality towards default. A model of the economy is presented featuring stochastic transition probabilities; credit instruments are valued via an ultraparabolic Hamilton-Jacobi system of equations discretized utilizing the method-of-lines finite difference method. Computations for a callable bond are presented demonstrating the efficiency of the method.

Key Education Issues In Review: Educational Funding, Unlv College Of Education

Policy Issues in Nevada Education: Policy Papers

As citizens of the U.S., we want the nation to have a world-class educational system that enables our children to compete with the best that other nations have to offer. To accomplish this, school funding plays an important role. Educational funding, however, is usually neither adequate nor equitable (Sims, 2004). Adequate funding ensures that all students are able to meet intended objectives and goals of education. Equitable funding ensures a sufficient level of funding distributed within states that accounts for additional needs based on various student characteristics. There are different costs for educating groups of students, and this should be …

Understanding English Language Learners: Incorporating Our Own Cultural Narratives In Tesol Education, Burcu Ates, Soonhyang Kim, Yurimi Grigsby

Journal of Praxis in Multicultural Education

Due to increasing globalization and immigration, there has been an increase in culturally and linguistically diverse (CLD) student population in the U.S. public school. Educating teacher candidates to become culturally aware, sensitive, and competent in order to meet the needs of this diverse population has been a concern of teacher education programs. As a result, various teaching methods and strategies are being implemented in teacher education programs. The purpose of this study was to explore the use of cultural narratives (CNs) as an instructional strategy in TESOL education. In this article, we share an example of how one teacher educator …

Ethnography In Action: Active Learning In Academic Library Outreach To Middle School Students, Samantha Godbey, Nancy Fawley, Xan Goodman, Susan Wainscott

Library Faculty Research

This article describes an outreach activity developed and coordinated by academic librarians as part of a state program for low-income middle school students. Rather than offering a traditional library tour, the library organizers wanted to provide the middle school students with a meaningful experience that would encourage active participation, critical thinking, and alleviate library anxiety. As a spin on the traditional tour, students applied an ethnographic approach to learning about the library. The authors describe the development and implementation of the activity and provide recommendations for other librarians involved in outreach to K-12 students.

The effects of lightning on space crafts, nuclear power plants, and sophisticated military equipment, are problems of increasing concern. The purpose of this research is to study the propagation of lightning through optically thick thunderclouds by applying knowledge of cloud micro-physics, the physics of lightning, diffusion approximations, and an understanding of the scattering …

Study Of Cuinte2 Quantum Dots Under Extreme Conditions, Howard Yanxon, Ravhi Kumar

McNair Poster Presentations

In recent years, Quantum Dot (QD) materials have attracted considerable interest due to their versatile properties and potential applications in electronics, biology, and optoelectronics, i.e. photovoltaic solar cell materials [1-2].

In 2000, RincÓn et al. reported an extensive study of the bulk material of CuInTe₂ along with its comparison to its ordered defect compounds [3]. The chalcopyrite structure consists of eight atoms per unit cell. This means there are 24 vibrational modes expected for the tetragonal structure. Out of the 24 modes, 21 vibrational modes belong to optical modes, and the other 3 modes are acoustical modes. The irreducible …

Nevada Should Opt-In To Organ Policy Changes, Alex Velto

Brookings Mountain West Publications

Organ donation shortages are a problem in Nevada. A shift in policy towards an opt-out system could more than double the number of registered organ donors in Nevada. A Libertarian Paternalistic strategy would allow potential donors to express their preference for organ donations more accurately. Currently Nevada abides by an opt-in policy where people are only organ donors if they explicitly request to become donors. Under an opt-out policy, people would be presumed organ donors unless they requested not to be donors. Policy changes during the 2015 Legislative session were a good start but failed to fully utilize behavioral economics …

A Taste Of Wittgenstein For Sfbt. 2: Philosophical Investigations, Nick Drury

Journal of Solution Focused Practices

This second of two papers provides an overview of Wittgenstein's later work and life from the perspective of what is called the 'resolute' or 'elucidatory' reading, for Solution-Focused Brief Therapists. This perspective takes the view that Witt­genstein's work can be seen as a form of therapy that enables us to be more at­ tuned to the world and each other.

Validation Of A Personality Scale: A Factor Analytic Approach, Leslie Forbush

UNLV Theses, Dissertations, Professional Papers, and Capstones

Researchers and clinicians alike make use of various assessment instruments to investigate variables of interest. These instruments include affective assessments, which require individuals to make judgments about themselves. To make these judgments individuals reflect upon their attitudes, interests, values, and personality traits and choose the corresponding response option that they feel best represents their current status with regards to the variable of interest for each question. The optimal number of response options to be included in such affective measurement scales has been greatly debated over the past several decades (Cox, 1980; Foddy, 1993; Jacoby & Matell, 1971; Jones & Loe, …

Factors Influencing The Perceived Impacts Of Medical Tourism Development On Quality Of Life, Courtney Suess

UNLV Theses, Dissertations, Professional Papers, and Capstones

A structural model is proposed and empirically examined that investigates factors influencing how residents perceive medical tourism's impact on quality of life domains and behavioral responses. A model based on social exchange is adapted as the basis of theory that medical tourism in a destination will affect community conditions and living experiences, which in turn influence residents' support for its development and tax paying behavioral intentions. Analyzed factors influencing how residents perceive medical tourism's affect on community conditions and living experiences underlying quality of life include overall community satisfaction, satisfaction with healthcare, attitudes towards medical tourism and economic performance.

Designing A Process To Reliably Split Extracted Teeth To Access The Dental Root Canal, Happy Singh Ghag

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction

Mesenchymal stem cell (MSC) research is a contemporary topic in modern healthcare. These cells have the ability to divide and generate progeny, which then become committed to specific and distinctive end-stage phenotypes, such as cartilage or bone (Caplan 1991). MSCs have been isolated from a variety of tissues such as the umbilical cord, bone marrow, adipose tissue (Ding, Shyu & Lin 2011) and dental pulp (Takeda et al 2008). Although dental pulp is a viable source for MSCs, peer reviewed research has given limited attention to its retrieval process through intentional tooth splitting of extracted teeth. The purpose of …

Possible Benefits Of Playing Music Video Games, Amanda Pasinski

UNLV Theses, Dissertations, Professional Papers, and Capstones

Music video games, such as Rock Band, are an emerging and popular genre of video game that allows non-musicians a taste of what it is like to be a musician. For most people, developing musicianship (or the process of becoming competent with a particular musical instrument) to an expert level is a long and difficult process that can take up to 10 years or over 7,500 hours to complete. Yet musicians tend to outperform non-musicians on a variety of tasks--showing greater motor coordination, better synchronization skills, and better pitch and tempo discrimination--and possibly show differences in related cognitive processes. However, …

Measuring The Effectiveness Of Race And Sports Book Complimentary Awards Program, Pak Szeto

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this paper is to develop a proper way to measure the effectiveness of complimentary award programs in race and sports books. Like most businesses, casinos seek to increase business volume by offering promotions. According to existing research on casino marketing, promotion activities are often measured by the change in business volume (Lucas & Kilby, 2008). Casino operators should be careful because an increase in business volume does not always equal an increase in profit. To create a positive effect on profit, a promotion must at least create enough gross revenue to offset its cost. Some casino executives …

Ore Classification And Breccia Formation In The 144 Zone Gold Deposit: A Chemical Replacement Model, Bare Mountain Range, Nevada, William Thomas Fischer

UNLV Theses, Dissertations, Professional Papers, and Capstones

The 144 Zone is an oxidized, breccia-hosted, disseminated gold deposit that formed along the contact between Early Cambrian Carrara Formation limestone and overlying Bonanza King Formation dolomite within the Bare Mountain range in southern Nevada. Gold mineralization occurs within a breccia body that contains a variety of breccia types. Research goals of this project included classifying clay, oxide and other minerals as well as breccia types to identify the habits of gold mineralization and the minerals associated with gold. Research was also aimed at determining the paragenesis of Au mineralization and brecciation in the 144 Zone. Underground mapping provided spatial …

Spectral Decomposition Of The Scattered Light Due To Deposits On The Solar Panel Surface, And Cross Correlated To Power Loss, Suzanna Ho

UNLV Theses, Dissertations, Professional Papers, and Capstones

The electric energy generated by solar panels declines due to dust particulates, bird deposits, water spots, and other contaminants that inhibit sunlight absorption and promote light scattering. As part of our research, we use cameras to capture images of solar panels, and analyze the images to detect the amount of scattered light. The more scattered light there is, the less light there is to penetrate the solar panel glass and reach the part of the panel that converts incident light to electric energy; therefore, less energy is generated. In this paper, we discuss the classification algorithm we developed to classify …

Thermal Impacts Of Salt On Sandstones And Mudstones In The Lusitanian Basin, Portugal, Brett Perry

UNLV Theses, Dissertations, Professional Papers, and Capstones

In order to assess the impact of salt structures on paleotemperatures in adjacent sedimentary rocks, a field based study which quantified thermally driven diagenetic products as a function of distance from salt was undertaken. Several salt diapirs are now exposed at the surface of the Earth within the Lusitanian Basin and offered a unique opportunity to document paleothermal anomalies by studying thermally controlled diagenesis in adjacent, exposed Upper Jurassic rocks. Four transects were chosen within Upper Jurassic rocks that contained both sandstones and mudstones. Quartz cementation and albitization of feldspars, both of which are thermally driven processes, were quantified in …

Gis Framework For Spatiotemporal Mapping Of Urban Flooding And Analyze Watershed Hydrological Response To Land Cover Change, Sayed Joinal Hossain Abedin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Urban flooding is a manmade disaster, and a recurrent problem in cities around the globe. Increased surface imperviousness due to urbanization along with inadequate drainage infrastructure system are the chief culprits for urban flooding. Flooding in an urban area brings about severe economic, structural, and environmental damages, and can be associated with casualties too. In order to evade flooding, an efficient flood model is imperative to study current flooding, and analyze flooding behavior to urban surface characteristics.

This research aims to develop a framework using Geographic Information System (GIS) to perform modeling and mapping of flood spatiotemporal variation in urban …

UNLV Theses, Dissertations, Professional Papers, and Capstones

While the use of RNS has provided groundbreaking theory and progress in this field, the applications still lack viable testing platforms to test and verify the theory. This Thesis outlines the processing of developing an instruction set architecture (ISA) and an instruction execution unit (IEU) to help make the first residue based general processor a viable testing platform to address the mentioned problems.

Consider a 32-bit ripple adder. The delay on this device will be 32N where N is the delay for each adder to complete its operation. The delay of this process is due to the need to propagate …

A Competency Model For Catering And Event Professionals Using A Modified Delphi Technique, Donnell G. Bayot

UNLV Theses, Dissertations, Professional Papers, and Capstones

As the market for face-to-face meetings and events has grown to one of the largest private sector industries, so has the market for catering, which is the largest budget line item for a meeting or event. Clients have become more demanding and at the same time more price-conscious. This has caused catering professionals and meeting and event planners' job responsibilities to change. Caterers and planners now have more crossover responsibilities and over more varied functional areas than ever before. In response, the National Association for Catering and Events (NACE), as the oldest and largest catering association in the world, formally …

International City/County Management Association 1999 Revenue Estimation Survey Revisited, Benjamin Bond

UNLV Theses, Dissertations, Professional Papers, and Capstones

In 1899 the National Municipal League declared that it was the duty of the Mayor to submit to the Council the annual budget of current expenses of the city, for almost as long, the budgeting process has been researched (Hou, 2006). Researching budgets is important and needed but comparatively little attention has been paid to revenue forecasts or to those responsible for the generation of revenue forecasts. Professional public administrators responsible for generating revenue forecasts have largely been overlooked in research. Judging by the lack of scholarly material available in academic journals, it appears the political process in which budget …

Speciation Of Pentavalent Technetium Complexes With Aniline And Thiobenzene Derivatives, Kyle E. Childs

UNLV Theses, Dissertations, Professional Papers, and Capstones

The reaction of bidentate aniline oligomers with pentavalent technetium has been investigated previously through the reaction of (n-Bu4N)TcOCl4 with o-phenylenediamine (PDA). The initial studies found that PDA reacted in a 1 to 2 molar ratio with pentavalent technetium in in ethanol. This study was expanded by the examination of a second aniline derivatives, 2-aminophenol (AMP)) and two thiobenzene derivatives (2-mercaptophenol (MP) and thiosalicylic acid (TSA)) to evaluate the kinetic formation of these complexes with pentavalent technetium. The pentavalent technetium complexes all showed reactivity with technetium having a coordination numbers of 5 with all ligands reacting in a 1 to 2 …

Social Network Analysis (Sna) Of Clark County, Nevada Tuberculosis (Tb) Case And Contact Investigation Data To Determine Pediatric Risk Factors For Disease Transmission, Darin Michael Cozatt

UNLV Theses, Dissertations, Professional Papers, and Capstones

Within the spectrum of childhood (infancy, early childhood, middle childhood, and adolescence), TB is a priority disease, and preventive care is recommended by the American Academy of Pediatrics (AAP)/Bright Futures initiative (AAP, 2008). Within the early childhood stage (15 months to 4 years), TB is classified as "HR2" (high risk 2), behind lead poisoning, which is "HR1" (AAP, 2008), the highest risk within this age range. Within the middle childhood stage (5 to 10 years), TB becomes an HR1. TB is preventable, and targeted screening is the best prevention method. The AAP/Bright Futures initiative further specifies the risk based on …

Mitigation Of Moving Shocks In An Expanding Duct, Veraun Chipman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Inviscid flow theory governs the bulk motion of a gas at some distance away from the walls (i.e. outside the boundary layer). That is to say, there are no viscous forces in the bulk flow, which is modeled using the Euler equations. The Euler equations are simply the Navier-Stokes equations with zero viscosity terms. An ideal inviscid fluid, when brought into contact with a surface or wall, would naturally slip right past it since the fluid has no viscosity. In real life, however, a thin boundary layer forms between the wall or surface and the bulk flow. Shock wave boundary …

Keeping In Touch: Exchange As An Adaptive Strategy In Southern Nevada, Timothy Joshua Ferguson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Archaeologists have always wondered about the extent of vessel movement in the American Southwest. Identifying vessel movement allows for the study of social interactions across a region and the role of ceramics in the adaptive processes of agriculturalists living in marginal, highly variable environments. In many instances, exchange may act as a way to reduce the risk of resource shortfalls by creating social ties in other areas. This research investigated the changing risk reduction strategies of households in the lowland Virgin region of southern Nevada by using geochemical methods to trace the exchange of locally produced pottery. It was hypothesized …
