A Case Study Of Organizational Change: College Restructuring In Response To Mandated Department Eliminations, Brandy Dyan Smith

UNLV Theses, Dissertations, Professional Papers, and Capstones

Faced with unprecedented budget cuts, Western University had implemented vertical cuts in the Spring of 2010 resulting in the elimination of two departments within their College of Education. Western University was not alone in its struggle. Institutions nationwide were coping with similar financial constraints, with freezes, consolidations, and eliminations becoming commonplace and threatening institutional quality.

The issue of how colleges and the leaders, groups, and individuals within them cope, process, and reorganize following eliminations has quickly gained importance, although there are few empirical studies to guide such changes. The existing literature on restructuring, particularly adaptability and change processes, has focused …

An Assessment Of Medical Care Provided By Nevada's High School Athletic Programs, Brooke Allen-Burnstein

UNLV Theses, Dissertations, Professional Papers, and Capstones

Even with preventative measures, injuries are inherent in sports. Almquist (2001) indicated that almost 60 percent of athletic injuries occur during practices. The American Medical Association recommends that all high schools establish an athletic medical team, but the National Athletic Trainers' Association (NATA) has estimated that only 42% of all high schools in the United States have access to a certified athletic trainer. In 2002, a NATA inter-association task force created the Appropriate Medical Care for Secondary School-Aged Athletes (AMCSSAA) Consensus Statement, which outlined the minimum standards for health care for adolescent athletes.

The purpose of this study was to …

A Polymerase Chain Reaction Method For The Detection Of Selenomonas Noxia, Arthuro Mehretu

UNLV Theses, Dissertations, Professional Papers, and Capstones

In recent studies, periodontal health has been linked to being overweight and/or obese. Among common oral bacteria, Selenomonas noxia has been implicated in converting periodontal health to disease. Selenomonas spp. have also been found in gastric ulcers, and were misdiagnosed as Helicobacter -like organisms, but no further studies were conducted. The increasing clinical and epidemiological importance of S. noxia necessitates the development of a rapid detection method. In this study, a TaqMan 16S rRNA based real-time Polymerase Chain Reaction (PCR) method was developed, optimized and evaluated for the rapid and specific detection of S. noxia . The 16S PCR assay …

Automating Construction And Selection Of A Neural Network Using Stochastic Optimization, Jason Lee Hurt

UNLV Theses, Dissertations, Professional Papers, and Capstones

An artificial neural network can be used to solve various statistical problems by approximating a function that provides a mapping from input to output data. No universal method exists for architecting an optimal neural network. Training one with a low error rate is often a manual process requiring the programmer to have specialized knowledge of the domain for the problem at hand.

A distributed architecture is proposed and implemented for generating a neural network capable of solving a particular problem without specialized knowledge of the problem domain. The only knowledge the application needs is a training set that the network …

Children with social, emotional, and conduct problems are at high risk for academic failure, peer rejection, conduct disorder, school dropout, delinquency, and drug and alcohol problems (Webster-Stratton, Reid, & Stoollmiller, 2008). A high priority for the United States public health and crime prevention is the prevention of aggressive and delinquent behavior during childhood and adolescence (Taylor, Eddy, & Biglan 1999).

Social skills trainings aim to increase the performance of key social behaviors that are important for children to succeed in social situations. Solutions may be …

Boundary Element Method (Bem) And Method Of Fundamental Solutions (Mfs) For The Boundary Value Problems Of The 2-D Laplace's Equation, Ermes Anthony Salgado-Ibarra

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this thesis we study the solution of the two dimensional Laplace equation by the boundary Element method (BEM) and the method of fundamental solutions (MFS). Both the BEM and MFS used to solve boundary value problems involving the Laplace equation 2-D settings. Both methods rely on the use of fundamental solution of the Laplace's equation (the solution of Laplace's equation in the distributional sense). We will contrast and compare the results we get using the BEM with results we get using the MFS.

The Utilization And Effectiveness Of The Hesi E(Square) Exit Exam As A Graduation Requirement Toward Increasing Nclex-Rnrtm Pass Rates In Baccalaureate Nursing Programs, Debra Henline Sullivan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Due to a desire to better prepare BSN students for the Nurse Council Licensure Examination for Registered Nurses (NCLEX-RN^® ) and to increase first-time pass rates, nursing programs across the US are using predictive testing to implement policies that require students to pass a standardized exit exam to graduate (National League for Nursing, 2010). Evolve Learning Systems owned by Elsevier, Inc. offers such an exit exam named the HESI E ² , which recommends a benchmark score to predict success on the NCLEX-RN^® .

Bryoecology In The American Southwest: Patterns Of Biodiversity And Responses To Global Change, John Carroll Brinda

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation combines investigation of the large-scale responses of bryophyte species diversity and distribution with small-scale physiological adaptations to global change. These two areas of inquiry are linked because one way to predict plant species responses to global change is to examine their distribution across current ecological gradients produced by factors such as latitude and elevation. By examining these biogeographic patterns one can identify those species that have a narrow tolerance and therefore are most sensitive to change. Selected bryophytes might then be used as indicator species in long-term monitoring programs. Where historical data exist, these can be used to …

Spectroscopic Methods Of Process Monitoring For Safeguards Of Used Nuclear Fuel Separations, Jamie Lee Warburton

UNLV Theses, Dissertations, Professional Papers, and Capstones

To support the demonstration of a more proliferation-resistant nuclear fuel processing plant, techniques and instrumentation to allow the real-time, online determination of special nuclear material concentrations in-process must be developed. An ideal materials accountability technique for proliferation resistance should provide nondestructive, realtime, on-line information of metal and ligand concentrations in separations streams without perturbing the process. UV-Visible spectroscopy can be adapted for this precise purpose in solvent extraction-based separations.

The primary goal of this project is to understand fundamental URanium EXtraction (UREX) and Plutonium-URanium EXtraction (PUREX) reprocessing chemistry and corresponding UV-Visible spectroscopy for application in process monitoring for safeguards. By …

Change Is Learning: Metacognition To Resolve Concerns During The Third Year Of The Implementation Of A Technological Innovation, Nola Allen-Raffail

UNLV Theses, Dissertations, Professional Papers, and Capstones

"We are living in a time of change. Rather than viewing change as a painful course of action, let's develop an understanding of how it works, how to facilitate the process, and how to learn from our experiences" (Hall & Hord, 2011, p. 18).

This study used a snapshot of a private Kindergarten-12^th grade school during the third year of the implementation of a technological innovation (RenWeb) to investigate teacher concerns during the process of change and gain insights into individuals' use of metacognition to resolve those concerns. Two primary research instruments were used, the Stages of Concern Questionnaire …

The Role Of Metrical Structure In Tonal Knowledge Acquisition, Matthew Rosenthal

UNLV Theses, Dissertations, Professional Papers, and Capstones

Experienced listeners possess a working knowledge of pitch structure in Western music, such as scale, key, harmony, and tonality, which develops gradually throughout childhood. It is commonly assumed that tonal representations are acquired through exposure to the statistics of music, but few studies have investigated potential learning mechanisms directly. In Western tonal music, tonally stable pitches not only have a higher overall frequency of occurrence, but they may occur more frequently at strong than weak metrical positions, providing two potential avenues for tonal learning. Two experiments employed an artificial grammar learning paradigm to examine tonal learning mechanisms. During a familiarization …

Adolphe Nourrit, Gilbert Duprez, And The High C: The Influences Of Operatic Plots, Culture, Language, Theater Design, And Growth Of Orchestral Forces On The Development Of The Operatic Tenor Vocal Production, Micheal Lee Smith Jr.

UNLV Theses, Dissertations, Professional Papers, and Capstones

The operatic tenor voice has evolved from a variety of influences. This document identifies four influences involved in the development of the operatic tenor voice and describes their impact on performance practices including the chest voice high C (C5). Modern tenors’ performance practices originate in the nineteenth century ascendance of an Italian singing technique. This particular singing technique achieved popularity when Gilbert Duprez sang the role of Arnold in Rossini’s Guillaume Tell with a do di petto (i.e. from-the-chest) production of sound rather than the mix of falsetto and head voice that was traditional at the time. The role of …

A Diffusion Tensor Imaging Software Comparison And Between Control Subjects And Subjects With Known Anatomical Diagnosis, Michael C. Moore

UNLV Theses, Dissertations, Professional Papers, and Capstones

Diffusion weighted imaging (DWI) is a magnetic resonance imaging (MRI) method that produces in vivo images of biological tissues weighted with the local micro-structural characteristics of water diffusion. Diffusion tensor imaging (DTI), a form of DWI, is useful when a tissue, such as the neural axons of white matter in the brain, has an internal fibrous structure that allows water to diffuse more rapidly in alignment with the fibers. Changes in the water diffusion pattern indicate changes in the fiber structure which can result from damage to the fibers. Measurements of the water diffusion patterns include overall diffusivity, Apparent Diffusion …

Association Between Childhood Demographics And Blood Lead Screening---Nevada Kindergarten Health Survey 2010, Lina Zhang

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lead, as a toxic substance, invades the human body, and gradually damages the organs. Oftentimes, elevated blood lead levels are not recognized until serious health issues are found. In the United States, approximately 250,000 children aged 1-5 years have elevated blood lead levels greater than 10 micrograms of lead per deciliter of blood (Centers for Disease Control and Prevention, 2004).

However, there is no effective treatment for lead poisoning. Chelation can merely decrease the blood lead levels but cannot reverse the existing damage. To prevent and control childhood lead poisoning, many studies have been conducted to investigate the sources of …

Bacterial Adherence Of Streptococcus Mutans And Lactobacillus Acidophilus On Poly-Methyl Methacrylate And Thermoplastic Polypropene Used In Orthodontic Retention, Lindsay Ann Pfepper

UNLV Theses, Dissertations, Professional Papers, and Capstones

Retention is required in the majority of orthodontic patients throughout the remainder of their life. The two primary removable appliances are known as the traditional Hawley retainer or the vacuum formed retainer. These appliances were developed to maintain the position of the dentition without sacrificing oral health. The orthodontic population is at a higher risk for caries due to plaque accumulation from poor diet, suboptimal oral hygiene and often lack of motivation. These two retainers occupy different niches and are comprised of different materials; therefore the retainers' effect on oral health could be very different. An understanding of which bacteria …

A Comparative Study Of Indicator Bacteria Present In Ice And Soda From Las Vegas Food Establishments, Kimberly Jo Hertin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Microbial analysis has long been used as an indicator of water quality. Since the passing of the Safe Drinking Water Act in 1974, microbial standards have been strictly set by the Environmental Protection Agency (EPA) to ensure that the public health is protected from bacterial pathogens. The bacteriological quality of water generally deteriorates as it travels from water treatment facilities through the main distribution system and into private plumbing and distribution systems. For example, Heterotrophic Plate Count (HPC) values typically increase once the water has entered plumbing devices such as beverage vending machines. Upon reaching a private facility, the opportunity …

The overall purpose of this research project is to survey experience and education of current dental students regarding domestic violence. Domestic violence has been recognized as one of our nation's most serious public health issues. Domestic violence can result in physical injury, psychological trauma, and sometimes death. Dentists can act as one of the first lines of intervention in recognizing common dental and facial trauma which may be associated with domestic violence victims including: broken teeth, facial bruising, and jaw fractures.

Current data suggest that education about domestic violence can help the dental professional in overcoming some of the barriers …

Effects Of High-Impedance-Contrast Boundary Upon Multi-Modal Seismic Surface Wave Data, Prajwol Tamrakar

UNLV Theses, Dissertations, Professional Papers, and Capstones

Synthetic studies and analyses of an experimental dataset were conducted to address the use of Rayleigh-type surface waves for estimation of shear wave velocity (VS) profiles of shallow bedrock sites. The shallow bedrock presents a high impedance contrast boundary which causes surface wave energy to be partitioned to higher modes. Idealized studies of hypothetical datasets and root-mean-squared calculations of error surfaces showed that if reliable dispersion data are available over a broad frequency spectrum, the VS profile can be recovered using the fundamental mode alone. However, when dispersion data are limited to a relatively narrow frequency band representing what might …

An Examination Of The Preparation, Experiences, And Attitudes Of Effective School Leaders Of Students With Disabilities: Voices From The Field, Patricia Ann Schultz

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research reflecting the preparation, experiences, and attitudes of effective school leaders of students with disabilities is scarce despite the fervent federal requirements changing special education over the past four decades. Although there is extensive literature on perspectives and contexts of disability, the legislative journey toward special education, inclusion and educational leadership, the expanding role of the principalship, principal attitudes on inclusion, and preparing educational leaders for inclusive education, a review of the related literature revealed an absence of the skill-set and disposition needed by school leaders who are improving academic achievement for students with disabilities.

This qualitative dissertation study documents …

Electrochemistry Of Pani/Metal Composites In Basic Solutions, Tamthinhan Quy

UNLV Theses, Dissertations, Professional Papers, and Capstones

Polyaniline (PANI) has been extensively investigated due to its unique conductivity, which is primarily dependent on the oxidation state of the material and the solution pH. PANI is an insulator when it is oxidized, and the solution pH exceeds four. Numerous attempts to extend PANI's conductivity to neutral and alkaline environments have been unsuccessful. However, our previous study has demonstrated that PANI/Pd composite is conductive and catalytically active in a basic solution, pH ∼ 12. Therefore, the conductivity and the electrochemical properties of PANI composites including PANI/Au, PANI/Pd and PANI/Pt were evaluated in basic solutions. The fundamental studies of PANI/metal …

Clarinet Performance Practices For Alberto Ginastera's "Variaciones Concertantes": Solutions For Orchestral Auditions And Performances, Thomas James Kmiecik

UNLV Theses, Dissertations, Professional Papers, and Capstones

The principal clarinet part of Alberto Ginastera's Variaciones concertantes (1953) requires the performer to execute a number of exposed passages that are considered impractical by many clarinetists as published. The Boosey & Hawkes edition of Variaciones concertantes was published for the B-flat clarinet. On account of this clarinet choice, the part exceeds the traditional upper range of the instrument in the third variation (Variazione in modo di Scherzo per Clarinetto ). Moreover, it requires very awkward fingering patterns in passages because they are written in the Phrygian mode of C-sharp. To avoid some of these technical obstacles, many professional …

Newe Country: Environmental Degradation, Resource War, Irrigation And The Transformation Of Culture On Idaho's Snake River Plain, 1805--1927, Sterling Ross Johnson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Idaho's Shoshone and Bannock Indians have long relied upon the Snake River. The waterway provides salmon and waters the vast Camas Prairie. On the prairie grows the Camas plant, the roots of which Shoshones and Bannocks harvest as a staple of their diet. Grass also grows on the prairie and the surrounding plains, which fed huge herds of bison that Shoshones and Bannocks also relied upon for food and skins to wear and trade. As a result of integration into the globalizing economy initiated by Meriwether Lewis and William Clark, indigenous peoples of the area and Euroamericans overhunted bison populations, …

Paired Positive Carbonate Carbon Isotope, Organic Carbon Isotope, And Oxygen Isotope Composition Study Across The Lower Mississippian Positive Carbon Isotope Excursion, Southeastern Nevada, Usa, Robert Alan Henry

UNLV Theses, Dissertations, Professional Papers, and Capstones

A prominent positive carbonate carbon isotope (delta13Ccarb) excursion of Early Mississippian age (ca 351 Ma) has been documented by previous studies from numerous sites globally. This delta13Ccarb excursion has been interpreted as resulting from enhanced organic carbon burial that removed 13C-depleted carbon from the ocean and atmosphere. Anticipated outcomes from enhanced organic carbon burial would include a similar positive excursion in organic carbon isotopes (delta13Corg) and a global cooling event resulting from reduced CO2 in the atmosphere and ocean. These predictions, however, were not tested sufficiently in previous studies. This research has tested these predictions through an integrated study of …
