Self-Stabilizing Leader Election In Dynamic Networks, Hema Piniganti

UNLV Theses, Dissertations, Professional Papers, and Capstones

The leader election problem is one of the fundamental problems in distributed computing. It has applications in almost every domain. In dynamic networks, topology is expected to change frequently. An algorithm A is self-stabilizing if, starting from a completely arbitrary configuration, the network will eventually reach a legitimate configuration.

Note that any self-stabilizing algorithm for the leader election problem is also an algorithm for the dynamic leader election problem, since when the topology of the network changes, we can consider that the algorithm is starting over again from an arbitrary state. There are a number of such algorithms in the …

Development Of Novel Biomarkers In Cancer: Detection Of Circulating Mir-141 As A Potential Prognostic Marker For Prostate Cancer, Jason Cadaoas Gonzales

UNLV Theses, Dissertations, Professional Papers, and Capstones

Prostate cancer (CAP) is the most common epithelial malignancy and the second leading cause of cancer deaths in American men. The identification of predictive and prognostic biomarkers in CAP patients is critical for improving clinical outcomes. Although the measurement of prostate-specific antigen (PSA) and radiographic studies are clinically approved to predict response to therapy, these tests can oftentimes prove to be inadequate in certain patients. Thus, it is important to discover new biomarkers to improve chances of survivability. We and others have shown that longitudinal measurements of circulating tumor cells (CTC) and lactate dehydrogenase (LDH) may aid in predicting response …

Parameterizable Network-On-Chip Emulation Framework, Jaya Suseela

UNLV Theses, Dissertations, Professional Papers, and Capstones

Networks-on-Chip (NoCs) have been proposed as a promising solution to complex on-chip communication problems. But there is no public accessible HDL synthesizable NoC framework which connects industrial level cores and runs real applications on them. Moreover, many challenging research problems remain unsolved at all levels of design abstraction; design exploration of NoC architecture for applications, scheduling and mapping algorithms, evaluation of switching, topology or routing algorithm for efficient execution of application and optimizing communication cost, area, energy etc Solution to solve the above problem calls for the development of synthesizable, parameterizable NoC Framework that would evaluate and implement the above …

Efficiency Of Fiscal Allocations In Site-Based Empowered Schools, Jerome Jay Meyer

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study implemented a two phase concurrent mixed-methods design to generate a greater understanding of how elementary schools with increased autonomy in fiscal decision making allocated their money, how their site-based decisions affected allocative efficiency, and how increased autonomy affected site-based decision making when compared with a set of matched control schools within a large urban district.

Phase I compared school site expenditure patterns of site-based empowered schools to demographically matched control schools and to all elementary schools within a large urban district over four years, 2004-05, 2005-06, 2006-07, and 2007-08. Expenditure data were collected from the In$ite data base …

The Crooked Median, Monica Zarazua

UNLV Theses, Dissertations, Professional Papers, and Capstones

Words search. There are specific points designated by written language, where one might stand for just a little while until the satisfaction of a pattern is revealed. In this collection of stories, one of the forces that serves as a catalyst for this search is the outside gaze. The gaze exerts itself onto characters. The characters may or may not be conscious of it, may or may not welcome it, but they must grapple with it. The gaze projects its needs and desires onto the characters. It seeks to control them, and it desires to be viewed with admiration, lowered …

Age And Petrogenesis Of The Roaring Mountain Rhyolites, Yellowstone Volcanic Field, Wyoming, Kathleen Marie Wooton

UNLV Theses, Dissertations, Professional Papers, and Capstones

Extracaldera rhyolites in the Norris-Mammoth Corridor of the Yellowstone Volcanic Field (YVF) appear to be unrelated to intracaldera volcanism, resulting instead from a new crustal magma source derived from northeastward propagation of the Yellowstone “melting anomaly.” The youngest extracaldera rhyolite unit, the Roaring Mountain Member (RM), is chemically distinct from the previous extracaldera lavas, reverting to more primitive compositions.

This study suggests that the majority of the RM rhyolites erupted from the same large-scale silicic magma system. Based on geochemistry and 40Ar/39Ar geochronology, the Crystal Spring mingled rhyolite and Obsidian Cliff rhyolite erupted concurrently at 59.1 ± 2.0 ka. The …

F5c: A Variant Of Faugere's F5 Algorithm With Reduced Gröbner Bases, Christian Eder, John E. Perry

Faculty Publications

The F5 algorithm for computing Gröbner bases achieves a high level of efficiency through the careful analysis of signatures assigned to each computed polynomial. However, it computes and uses many polynomials that turn out to be redundant. Eliminating these redundant polynomials is a non-trivial task, because they correspond to signatures required for reduction. This paper revisits the theory underlying F5 and describes F5C, a new variant that prunes redundant polynomials, then re-computes signatures to preserve correctness. This strategy successfully reduces both overhead and execution time. (C) 2010 Elsevier Ltd. All rights reserved.

The Allocation Of Time And Goods: Three Essays On American Household Shopping Behavior, Jing Cai

Dissertations

Consumers’ shopping behavior connects market goods expenditure with the out of- market time allocation in their daily time use. This study is composed of three essays. In the first essay, data are collected from the American Time Use Survey and it is found that an individual’s time devoted to shopping is positively determined by opportunity cost of time. Grocery shopping and other shopping, as two distinct types of shopping, react differently to a series of individual and household characteristics as well as by seasons. The corresponding marginal effects also differentiate between shopping time, leisure time, and home production time. In …

Counseling Professionals' Attitudes Toward Transgender People And Responses To Transgender Clients, Emily A. Nisley

Dissertations

The multicultural counseling movement emphasizes the critical nature of counselor attitudes in providing culturally competent service (e.g., Sue, 2001; Sue, Arredondo, & McDavis, 1992; Sue et al, 1982; Sue & Sue, 2003). Until recently, however, the counseling professions have paid little attention toward transgender people as a cultural minority group. The purpose of this study was to conduct the first assessment of counseling professionals' attitudes toward transgender people and to examine relationships between such attitudes and responses to a transgender client.

A national convenience sample of 138 master's and doctoral level counselors and counseling psychologists, recruited via electronic mailing lists, …

Confidence Intervals And Tests On The Difference Of Means Of Two Delta Distributions, Karen Grace Villarente Rosales

Dissertations

Various research fields produce data that are lognormally distributed and inflated with zero values. This type of data follows a delta distribution. In this study, we want to extensively investigate different interval and hypothesis testing methods for comparing the means of two delta populations to see which methods are optimal under different conditions of the populations.

For confidence intervals, existing MVUE methods are extended to two sample cases and compared to classical and two proposed robust methods. We investigated the performance of the classical Student's t, Welch t, and Wilcoxon-based interval to see if these methods really perform badly on …

Composing Ourselves: Utilizing Literacy Narratives To Promote Knowledge And Reflection In Preservice Secondary English Teachers, Cheryl Henderson Almeda

Dissertations

My research entails examining and interrogating the literacy narratives written by six preservice secondary English teachers before their first semester of teaching. After writing their literacy narratives, these teachers worked together in two focus groups to consider, celebrate, and interrogate their memories they recorded in their narratives. They shared conversations which focused on their reflections, their teaching strategies, and the ideas they embraced as newly forming teachers.

This study considers claims made by Dewey (1933), Lortie (1975), Schulman (1986), and others, who emphasize the importance of learning through observation and the intuitive nature of reflective learning and teaching. It emphasizes …

The Fertile Dark, Jacob M. Martin

Dissertations, Theses and Capstone Projects (Full IR Collection)

The Fertile Dark is a portfolio comprised of approximately forty poems and an introductory essay. All of the poems were written and revised by me while I was a student in the Master of Arts in Professional Writing program, working under the direction of Dr. Jim Elledge and Dr. Ralph Wilson. Although no single theme characterizes the portfolio, the interplay between darkness and light may be seen throughout. As the son of a minister, I am fascinated by these elemental forces and how they shape our lives, our realities, and our beliefs.

At-Will Employment In The Public Sector: A Case Study Of The Georgia Reform, Olayinka Tejuoso

Dissertations, Theses and Capstone Projects (Full IR Collection)

Prior to the advent of at-will employment, elected officials and public managers have laid blame on government in the United States of being distended, unproductive, and impassive. The Civil Service Reform Act of 1978 abolished the Civil Service Commission and endorsed reformation of workforce practice and policies. Many states in the United States have followed suit, but with limited measures (Battaglio 2010). It is apparent, nonetheless, that a lot of political executives and professional managers have lingered on in aggravation, and are pushing for more considerable influence and stiffness over employees. As a consequence of at-will employment over the years, …

It provides a descriptive analysis of how these mechanisms interact with each other for effective emergency management. Most importantly, this study provides a unique insight on how Georgia prepared for, mitigated against, responded to, and recovered from the September 2009 flood. There are several important mechanisms for intergovernmental collaboration; among them are the national incident management system, the incident command system, and the emergency management assistance compact. During disasters these mechanisms interact with each other to …

Employment Of People With Criminal Records: An Exploratory Study Of The State Of Georgia, Michael Dutcher

Dissertations, Theses and Capstone Projects (Full IR Collection)

Individuals in Georgia with criminal records have many barriers and collateral consequences which impact their ability to find employment upon release from prison. Collateral consequences are those repercussions which impact the ex-offender’s civil liberties after they are released from prison. Research has shown that ex-offenders who do not find gainful employment upon release from prison are more likely to return to prison than those who find gainful employment after they are released.

The purpose of this exploratory study is to examine the current state and federal programs along with nonprofit organizations and discuss how they affect Georgians with criminal records. …

Community's Safety Net: A Comparative Analysis Of The Role Of Nonprofit Hospitals In Barrow And Clayton Counties In Providing Services To Its Medicaid Population, Carlene Coggins, Julie John

Dissertations, Theses and Capstone Projects (Full IR Collection)

Nonprofit hospitals serve as part of the healthcare safety net to deliver a significant level of care to low-income, uninsured, underinsured, Medicaid and other vulnerable groups in society. Safety net hospitals are defined as those hospitals where at least 10 percent of the costs of care provided is uncompensated. Nonprofit hospitals are granted tax exemptions from the government and in exchange they are required to meet community benefit standards which include offering care to a relatively large proportion of uninsured or socially disadvantaged individuals.

Increasing poverty levels due to rising unemployment, foreclosures and economic distress have placed the safety net …

Confiscation Or Serving The Public Good?, Gabriel Aramian

Dissertations, Theses and Capstone Projects (Full IR Collection)

Throughout the past decade, the idea of overreaching government policy has sparked a disconcerting impression among the American people. Is it true that the government can take private property for the benefit of private interests? After the Supreme Court decision in Kelo v. City of New London (2005), a public firestorm erupted, sparking massive public and political discourse that rocked the sphere of property rights nationwide. Although much of the scrutiny was critical, there were those that attempted to illustrate not only the importance of eminent domain, but the damage that excessive limitation through public policy might cause.

The purpose …

Environmental Impact Of The Euro-American Emigration Through Southwestern Idaho (1840-1862): Effect On Native Lifeways, Garrett G. Webb

Boise State University Theses and Dissertations

It has traditionally been held by historians that during the period of Euro-American emigration that preceded settlement of southwestern Idaho in 1863, environmental degradation stemming from emigrants undermined native lifeways and incited conflict between the two cultures. The quantitative nature of the emigration, potential ecological impacts, and the historical perspective all suggest that such claims cannot be substantiated. Overall, the negative effect upon native lifeways may have been significantly less than what is maintained by the current historical paradigm. Instead, conditions of mutual interdependence that existed during the fur trade (1811-1840 A.D.) likely persisted throughout the period of emigration. It …

Ancient And Recent Demographic Events Influence Mitochondrial Dna Diversity In An Immigrant Basque Population, Michael Christopher Davis

Boise State University Theses and Dissertations

The Basques are an ancient people, considered by many anthropologists to represent the oldest extant European population. Because of this, they have been the subject of numerous sociological and biological investigations. The Basque Diaspora, a relatively recent demographic expansion of the Basque population, has until now been overlooked in molecular genetic studies. Samples were taken from 53 individuals with Basque ancestry in Boise, Idaho, and the mitochondrial DNA (mtDNA) sequence variation of the first and second hypervariable regions were determined. Thirty-six mtDNA haplotypes were detected in the sample. Comparing the genetic diversity in the Idaho sample with other Basque populations, …

Self-Stabilizing Group Membership Protocol, Mahesh Subedi

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this thesis, we consider the problem of partitioning a network into groups of bounded diameter.

Given a network of processes X and a constant D, the group partition problem is the problem of finding a D-partition of X, that is, a partition of X into disjoint connected subgraphs, which we call groups, each of diameter no greater than D. The minimal group partition problem is to find a D-partition {G1, ... Gm} of X such that no two groups can be combined; that is, for any Gi and Gj, where i ≠ j, either Gi U Gj is disconnected …
