Exploration Of The Nature Of The Work Done By United States Marshals Service Employees In The District Of Nevada, Michael Robin Schlaerth Jan 2002

Exploration Of The Nature Of The Work Done By United States Marshals Service Employees In The District Of Nevada, Michael Robin Schlaerth

UNLV Retrospective Theses & Dissertations

For the first time in its 212 year history, the United States Marshals Service created a position for employees specifically designated to assist district offices experiencing administrative and operational problems. This move was promoted by a recruiting session in April of 2001 which was designed entirely to train individuals for the job entitled GS-082. This move is the result of the agency's overall need for more labor. However, while these agents carry the title of "Deputy Marshal", they do not require the same intense training of the standard GS-1811 agents, as their duties do not demand it. Employees in the …

Investigation Of Charge-Transport Models For Organic Light-Emitting Devices, Richard Simon Schofield Jan 2002

Investigation Of Charge-Transport Models For Organic Light-Emitting Devices, Richard Simon Schofield

UNLV Retrospective Theses & Dissertations

Organic light emitting devices (OLEDs) show promise for use in the display industry, particularly as the active display portion of flat panel televisions and monitors. Unfortunately important material fundamentals of these organics are not well understood, like charge transport, charge injection and exciton formation/relaxation. It is therefore useful to attempt to understand the behavior of these materials in the physical state that they will be used in: thin films. There have been two models proposed to explain charge transport in these materials and it is the purpose of this work to examine them using a group of similar materials. These …

Bird Perches And Soil Amendments As Revegetation Techniques For Landslides In Puerto Rico, Aaron Blakely Shiels Jan 2002

Bird Perches And Soil Amendments As Revegetation Techniques For Landslides In Puerto Rico, Aaron Blakely Shiels

UNLV Retrospective Theses & Dissertations

Landslides represent one of the most severe natural disturbances in tropical rainforests. The loss of the topsoil layer is detrimental to plant establishment and plant succession as it contains the soil seed bank, as well as the majority of the nutrients essential for plant growth. In this study, I introduced bird perches to six Puerto Rican landslides with three types of surfaces (bare, climbing fern, grass) to test the limitation of bird-dispersed forest seeds in landslides and to accelerate forest seedling establishment. I also mixed four soil amendments (Cecropia leaves, Cyathea fronds, forest soil, and commercial fertilizer) in five recent …

Negotiation And Autonomy In A Fast Food Restaurant, Eric Orion Silva Jan 2002

Negotiation And Autonomy In A Fast Food Restaurant, Eric Orion Silva

UNLV Retrospective Theses & Dissertations

This study is an attempt to apply the negotiated order perspective to the analysis of the lived experience of workers in two franchised fast food restaurants. Drawing primarily on the work of Anselm Strauss (1978) and D. H. J. Morgan (1975), I have examined data taken from auto-ethnographic and overt observation. I found that workers in different negotiation contexts would use implicit and explicit negotiation to achieve internal and external goals. Worker's negotiation strategies depended on the actor's individual proclivities and their interpretation of the negotiation context. Issues subject to negotiation included wages, the schedule, the amount of effort expended, …

Breast Cancer Screening Behaviors And Beliefs In College Women, Leslie Ann Snyder Jan 2002

Breast Cancer Screening Behaviors And Beliefs In College Women, Leslie Ann Snyder

UNLV Retrospective Theses & Dissertations

Despite recommendations by health professionals and the American Cancer Society, few women perform breast self-examinations (BSE) or have clinical breast examinations (CBE) on a regular basis. The current study used self-reports from 453 college women under 30 years of age to investigate factors that may influence breast cancer screening behaviors. Examiners and non-examiners were compared on a series of variables: (1) health beliefs and practices (personal risk estimates for breast cancer, risk reduction expectancies, perceived susceptibility to breast cancer, perceived seriousness of breast cancer, perceived benefits of BSE, perceived barriers to BSE, confidence in performing BSE, general health motivation, the …

Bench-Scale Modeling To Evaluate The Mechanical Effects Of Subsidence On A Monofill-Type Landfill Cover, Yuboon Tan Jan 2002

Bench-Scale Modeling To Evaluate The Mechanical Effects Of Subsidence On A Monofill-Type Landfill Cover, Yuboon Tan

UNLV Retrospective Theses & Dissertations

A bench-scale model was developed to simulate the effects of subsidence on compacted monofill-type landfill covers for the low-level radioactive waste landfills of the Radioactive Waste Management Sites of the Nevada Test Site. Of particular interest is the collapse mechanism of the cover with respect to the soil density and compaction water content. Collapse in covers compacted at lower water content was in the form of progressive upward caving by consistent raveling, with distinct, continuous preferential pathways for saturated fluid flow and vapor migration formed. (Abstract shortened by UMI.).

Robert Hugh Benson And The Catholic Literary Revival In Edwardian England, Chad Philip Stutz Jan 2002

Robert Hugh Benson And The Catholic Literary Revival In Edwardian England, Chad Philip Stutz

UNLV Retrospective Theses & Dissertations

Robert Hugh Benson was a popular religious author in Edwardian England; however, he has been all but forgotten by posterity. This study re-examines Benson's contribution to the Catholic Literary Revival, a movement rooted in Romanticism. Benson utilized a "ministerial approach" to spread his message of renewal. Whereas other Revivalists wrote official histories, Benson wrote historical novels to advance the claim that the sixteenth century was responsible for British social disintegration. By presenting history as art, Benson presented his Christian worldview in a palatable form. Benson also had a complex relationship with 1890's Aestheticism. Though he wrote a novel denouncing its …

The Asymptotic Behavior Of The Integer Solutions Of The Rosenberger Equations, Kensaku Umeda Jan 2002

The Asymptotic Behavior Of The Integer Solutions Of The Rosenberger Equations, Kensaku Umeda

UNLV Retrospective Theses & Dissertations

The Rosenberger equations are equations of the form: ax 2 + by2 + cz 2 = dxyz, where the sets of coefficients ( a, b, c, d) are all integers such that each of a, b, and c divides d, and the equations themselves have infinitely many integer solutions. Rosenberger has shown that there are only six such sets of coefficients, one of which is the Markoff equation, x2 + y2 + z2 = 3xyz. Zagier investigated the asymptotic behavior of the integer solutions of the Markoff equation. In this paper, we apply Zagier's techniques to the Rosenberger equations and …

Power And Political Process: The Case Of The Ivanpah Airport, Amy Gayle Walker Jan 2002

Power And Political Process: The Case Of The Ivanpah Airport, Amy Gayle Walker

UNLV Retrospective Theses & Dissertations

This thesis examines power and political processes involved in the decision to construct a second commercial airport for Las Vegas, NV and the southern Nevada region. Using interview data and document analysis I argue that the organizational capacity of the state and its relative autonomy enabled state actors to dominate the airport's development process by defining the need and setting the agenda for the project. Additionally, state officials acquired the land for the project by circumventing established mechanisms for public participation and involvement. The findings support a state-centered approach to understanding who wields power and how in political processes. Ultimately, …

The Effectiveness Of Reading Programs For The Intermediate Remedial Student, Hope Ann Walter Jan 2002

The Effectiveness Of Reading Programs For The Intermediate Remedial Student, Hope Ann Walter

UNLV Retrospective Theses & Dissertations

Research on remedial reading programs has a controversial history. Although extensive research has been conducted on pull-out programs, far less research has evaluated remedial reading programs within the regular classroom. This study investigated whether using the basal or a new program, Project STARS, would produce reading gains in intermediate remedial readers. It was hypothesized that Project STARS subjects would show a greater academic gain in three areas. To evaluate this hypothesis, 46 students were assessed in August and December to determine the amount of growth for each student after instruction in either the Project STARS method or the basal text. …

From Equi-Graphical Sets To Graphical Permutations: A Problem Of Degrees In Graphs, Michael Lee Watson Jan 2002

From Equi-Graphical Sets To Graphical Permutations: A Problem Of Degrees In Graphs, Michael Lee Watson

UNLV Retrospective Theses & Dissertations

A set {a1, a2,.., an} of positive integers with a 1 < a2 < &cdots; < an is said to be equi-graphical if there exists a graph with exactly ai vertices of degree ai for each i with 1 ≤ i ≤ n. It is known that such a set is equi-graphical if and only if i=1nai is even and an≤i=1n-1 ai2 . This concept is now generalized to the following problem: Given a set S of positive integers and a permutation pi on S, determine when there exists a graph containing exactly ai vertices of degree pi(ai) for each i (1 ≤ i ≤ n). If such a graph exists, then pi is called a graphical permutation; In this paper, the graphical permutations on sets of size four are characterized and using a criterion of Fulkerson, Hoffman, and McAndrew, we show that a permutation pi of S = {a1, a2, .. , an}, where 1 ≤ a1 < a2 < &cdots; < an and such that pi(a n) = an, is graphical if and only if i=1naip ai is even and an≤i=1n-1 aipai .

Modeling Image Databases Using Xml Schema, Min Xu Jan 2002

Modeling Image Databases Using Xml Schema, Min Xu

UNLV Retrospective Theses & Dissertations

This thesis presents a model for still images in order to support content-based querying and browsing by hierarchical tree structures and object relational graphs. We use the extensible markup language (XML) schema to illustrate and exemplify the proposed model because of its interoperability and flexibility advantages. Of primary interest is the notion of complex types and referential integrity to fully describe the physical and semantic properties of images. XQuery is used to support query processing. We further show how these complex types of XML schema can be used to overcome the shortcomings of reported image database descriptions in the literature.

The Establishment Of The Oligomeric Purity And Molecular Structure For N-Methylated Bis(8-Hydroxyquinoline) Zinc (N = 0, 2, 4, And 5), Anna Rose Falkowitz

UNLV Retrospective Theses & Dissertations

Znq2 has been studied as electroluminescent material. However, no correlation of the structure of Znq2 to resulting device properties has been established. Most reports of Znq2 as an electroluminescent material have not considered the impact of higher order molecular structures on the device properties. By utilization of size exclusion chromatography it has been determined that the dominant species of nMeq2Zn (n = 0, 4, 5) is tetrameric in crystalline form dissolved in chloroform, in thermally vapor deposited films, and in crystalline form dissolved in chloroform and DMSO. The 2Meq2Zn was determined to be solely monomeric under the previously mentioned condition. …

Self-Stabilizing Wormhole Routing, Anthony Brandon Kenitzki Jan 2002

Self-Stabilizing Wormhole Routing, Anthony Brandon Kenitzki

UNLV Retrospective Theses & Dissertations

Parallel and distributed systems are composed of individual processors that communicate with one another by exchanging messages through communication links. When the sender and the receiver of a message are not direct neighbors, intermediate processors must cooperate to ensure proper routing; Wormhole routing is most common in parallel architectures in which messages are sent in small fragments called flits. We assume that each processor will contain a single fixed-size flit buffer for each incoming link. A processor must forward the flit in a given link buffer to another processor before receiving another flit on that link. This permits messages to …

Ecology And Growth Of Tamias Palmeri And Testing Of A Protocol To Monitor Habitat Relationships, Christopher Eric Lowrey

UNLV Retrospective Theses & Dissertations

The ecology of Tamias palmeri is investigated. Presence-absence and relative abundance of T. palmeri are related to principle component scores of habitat variables using logistic regression and multiple linear regression, respectively. Relative abundance of Tamias palmeri estimated with live capture-recapture was positively correlated with shrub cover and negatively correlated with slope. Timing of emergence from dens by juveniles was earlier and weights of juveniles were greater in ravine areas as compared to upslope areas. Track plates were not correlated with trap captures. Track plate success was not correlated with habitat variables. The results of this study were used to build …

Representation Of Special Polynomials By The Cycle Indicator, Jack Lund Schofield Jan 2002

Representation Of Special Polynomials By The Cycle Indicator, Jack Lund Schofield

UNLV Retrospective Theses & Dissertations

Certain classes of special functions have been shown to have Cycle Indicator representations as well as recurrence relations. Most remarkably, it is shown how the Cycle Indicator can be used to unify or generalize special functions. Methods of unifying special functions are elaborated on. It follows that classical special functions with simple logarithms of their generating functions can be classified in this way. Also, there are counter-examples where the Cycle Indicator doesn't represent the special functions given; This thesis represents a study of a journal article called "Cycle Indicators and Special Functions" by Leetsch C. Hsu and Peter Jau-Shyong Shiue …

From Neglected Waste To Protected Space: An Administrative History Of Mojave National Preserve, Eric Charles Nystrom Jan 2002

From Neglected Waste To Protected Space: An Administrative History Of Mojave National Preserve, Eric Charles Nystrom

UNLV Retrospective Theses & Dissertations

The Mojave National Preserve, a unit of the National Park Service, was created in 1994 in southeastern California. Its 1.6 million acres were used historically for extractive industries such as mining and ranching, and its recent history was shaped by the land's proximity to urban Los Angeles. The preserve was the fruit of a long political battle between environmental activists and conservative opponents, and the park's final administrative form and subsequent management was indelibly altered by the compromises made during the legislative fight. The park's subsequent history, including innovative planning efforts, a 1995 attempt by opponents to eliminate the preserve's …
