UNLV Theses, Dissertations, Professional Papers, and Capstones

The Uses and Gratifications of Dance Reality Shows

Competition based dance reality shows are a sub-category under the reality television show genre. One way to add to the growing body of research about reality television shows is to study each sub-category individually in terms of uses and gratifications theory. Therefore this research looked into the reasons why people watch dance reality shows. Since dance is an art form that has deep historic roots, has experienced highs and lows in terms of public perception and has experienced a strong resurgence recently within the realm of reality television, it proves to be …

Incentive Based Approach To Find Selfish Nodes In Mobile P2p Networks, Hemanth Meka, Sanjay K. Madria, Mark Linderman

Computer Science Faculty Research & Creative Works

In a Mobile P2P (M-P2P) network, selfish nodes can drop packets to affect the efficiency of the whole network. Therefore, we propose a simple and efficient mechanism using virtual currency to identify selfish nodes in the network. Each node issues a receipt to its broker to prove that it has provided a forwarding service. based on receipts received each broker provides well-behaved nodes some virtual currency whereas selfish nodes are punished on dropping packets to make the network more efficient. When compared to other known approaches, our scheme provides real-time detection of selfish nodes and does not require/assume the presence …

Delayed Matching To Sample: Reinforcement Has Opposite Effects On Resistance To Change In Two Related Procedures, John A. Nevin, Timothy A. Shahan, Amy L. Odum, Ryan D. Ward

Psychology Faculty Publications

The effects of reinforcement on delayed matching to sample (DMTS) have been studied in two within-subjects procedures. In one, reinforcer magnitudes or probabilities vary from trial to trial and are signaled within trials (designated signaled DMTS trials). In the other, reinforcer probabilities are consistent for a series of trials produced by responding on variable-interval (VI) schedules within multiple-schedule components (designated multiple VI DMTS). In both procedures, forgetting functions in rich trials or components are higher than and roughly parallel to those in lean trials or components. However, during disruption, accuracy has been found to decrease more in rich than in …

Assessing The Impacts Of Surface Water Removal For Use In Natural Gas Extraction On A Watershed Level, Carrie Ann Davis

Graduate Theses and Dissertations

In this study, the Soil and Water Assessment Test (SWAT) was used as a tool to predict whether diffuse water removal from the Cadron Creek watershed for use with natural gas development would have an impact on downstream flow within the watershed. Cadron Creek watershed expands across four counties within Arkansas and is located in the Fayetteville Shale Gas region. This region is experiencing significant growth in natural gas development. Successful development of shale gas depends on the identification of what water supplies are available for production without interfering with community and environmental needs. The SWAT model used to evaluate …

Rickettsia Felis In Cat Fleas, Ctenocephalides Felis Parasitizing Opossums, San Bernardino County, California, Kyle F. Abramowicz, J. W. Wekesa, C. N. Nwadike, Maria L. Zambrano, Sandor E. Karpathy, D. Cecil, J. Burns, R. Hu, Marina E. Eremeeva

Environmental Health Sciences: Faculty Publications

Los Angeles and Orange Counties are known endemic areas for murine typhus in California; however, no recent reports of flea-borne rickettsioses are known from adjacent San Bernardino County. Sixty-five opossums (Didelphis virginiana) were trapped in the suburban residential and industrial zones of the southwestern part of San Bernardino County in 2007. Sixty out of 65 opossums were infested with fleas, primarily cat fleas, Ctenocephalides felis (Bouché, 1835). The flea minimum infection rate with Rickettsia felis was 13.3% in pooled samples and the prevalence was 23.7% in single fleas, with two gltA genotypes detected. In spite of historic records of murine …

Unnecessary Evil: An Examination Of Abu Ghraib Torture Photographs As Postcolonial Resistance Rhetoric, Patrick Gerhardt Richey

Dissertations

The purpose of this dissertation is to examine the rhetorical nature of visual artifacts in a postcolonial context. In order to examine the nature of visual artifacts as a form of resistance against static ideologies and prevailing power structures, the author uses both media and cultural artifacts created in response to photographs taken of abused prisoners at Iraq’s Abu Ghraib Correctional Facility. The dissertation adds to scholarly knowledge of communication by addressing the intersections of iconographic visual communication and postcolonial resistance rhetoric. The dissertation provides a scholarly review of the Abu Ghraib prison scandal, as well as of literature explicating …

The Relationship Between Perceptions Of School Climate And Student Achievement In Schools That Use Jostens' Renaissance Programs, Amy Yarborough Coyne

Dissertations

Each school has unique attributes and a personality that gives the school a distinct climate. Psychological qualities that schools possess might include trust, collaboration, cooperation, teaching attributes, expectations, community involvement, and engagement (Rhodes, Camic, Milburn, & Lowe, 2009). Given information regarding school climate, relationship needs, and motivation, the purpose of this study was to examine the perceptions of teachers involved in change and improvement processes and to determine whether academic change was related to the use of programs such as Jostens’ Renaissance.

The participants of this study consisted of 242 faculty and staff from five public schools from three separate …

Understanding Corrosion Protection And Failure Through Model Polymers In Thin Films, Joshua Smith Hanna

Dissertations

When developing a model polymeric system to facilitate in the detection of molecular and microscopic events that preface macroscopic corrosive failure; a better understanding of how polymers can indicate corrosion was accomplished. Initially, the thought that molecular chain scission as a necessity for corrosion to occur had to be tested. Through the utilization of high molecular weight thermoplastic (HMWTP) model polymers, it was found that corrosion protection did not correlate to the quantity of weak bonds within an epoxy-amine polymer matrix. Therefore more sensitive methods of detecting corrosion had to be developed since changes within the polymer matrix did not …

Determining The Individual, Organizational, And Community Level Outcomes Of A Community Leadership Development Program As Perceived By The Program Alumni, Susan Johnston Bush

Dissertations

The need for community leaders is increasing while the supply of community leaders is decreasing, leaving a gap in community leadership. Community leadership development programs (CLDP) are the most common approach to leadership development, yet the effects of CLDPs are rarely determined. In order to sustain programs that develop potential community leaders, program outcomes at the individual, organizational, and community levels must be identified.

This exploratory, non-experimental quantitative study used Black’s (2006) Leadership Program Outcomes Measure (LPOM) to determine CLDP alumni’s perceptions of the individual, organizational, and community level outcomes associated with participation in the CLDP; to describe the socio-demographic …

The purpose of this qualitative study was to describe and explore American male elementary teachers’ perceptions on factors that contribute to decisions to remain in or exit the teaching field, specifically elementary education. Ten African American male elementary teachers participated in the study. The theory from this study was the Motivation–Hygiene theory (Herzberg, Mausner, & Snyderman, 2010). The study was conducted on the basis of Phenomenology with the use of Maslow’s Hierarchy of Needs (Maslow, 1954). Research yielded African American males’ perceptions. Data were collected consisting of one on one interviews. The interview data were analyzed and collected using Colaizzi’s …

The Effectiveness Of A District-Wide Training Initiative On Determining Preparedness Of Educational Leaders In A Large, Southeastern Louisiana School System, Jeanne Bordelon Wagner

Dissertations

A nationwide shortage of qualified, experienced applicants to fill the roles of educational leaders has led to a hiring crisis among school districts across America. The diminishing pool of applicants, accompanied by a high turnover rate of practicing administrators and increasing accountability demands, has revealed the importance of recruitment and retention of educational leaders. As the roles of school administrators are constantly evolving and increasing in complexity, recruiting skillfully trained personnel proficient in all dimensions of school leadership is a catalyst for increasing student achievement and for reducing principal attrition rates. The purpose of this research was to reveal perceived …

Fas-Activated Serine Threonine Kinase 4 Is A Mitochondrial Protein, Johnna St Clair

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Mitochondria play an essential role in eukaryotic cells, supplying energy levels which vastly exceed those available to prokaryotes. They rely heavily on the import of nuclear encoded proteins for their function. The FAST family of proteins which are synthesized in the cytoplasm and imported into mitochondria are an example of this. The FAST family has not been well characterized, and next to nothing is known about several FAST family members. In the following I have reviewed what is known about each member of the FAST protein family including conserved domains, structures, including roles in cellular function, apoptosis and disease. Additionally, …

A Stochastic Segmentation Model For Joint Dna-Rna Microarray Data Analysis, Yi Su

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

DNA copy number change and epigenetic alteration often induce abnormal RNA expression level and have been linked to the development and progression of cancer. While various methods have been proposed for studying microarray DNA copy number and RNA expression data respectively, little statistical work has been done in modeling the relationship between the two. We propose for the joint analysis of the two types of data a new stochastic change-point model with latent variables, and an associated estimation procedure. Our method integrates hidden Markov model with Bayesian statistics to yield joint posterior distribution of DNA and RNA signal intensities throughout …

Contemporary Manhattan Cartographies: Ephemeral Public Projects In New York, Andrew Wasserman

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

This dissertation considers the emergence of a cartographic public practice in both contemporary art and contemporary cities, attending to the ways in which ephemeral public projects create map-like objects that diverge from official urban projections. Rather than marking a single location, such projects structure networked connections between several sites, transforming undifferentiated urban spaces into legible urban places. Evaluation of this recent cartographic turn entails the triple consideration of placemaking, placemakers, and placemarkers as constructing spatialized identities for different neighborhoods and setting forth wayfinding strategies within these same neighborhoods. Focusing on Manhattan, the dissertation surveys how the borough has served as …

The Role Of Dystroglycan In Differentiating Oligodendroglia And Cns Myelination, Christopher Edward Eyermann

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

During central nervous system (CNS) development, individual oligodendrocytes myelinate multiple axons, thus requiring the outgrowth and extensive branching of oligodendroglial processes. Extrinsic cues including the extracellular matrix (ECM) molecule laminin regulate oligodendrocyte maturation; indeed, laminin-deficient mice have fewer myelinated axons, which may indicate a defect in the ability to properly extend and branch processes. It remains unclear, however, to what extent ECM receptors contribute to oligodendroglial process remodeling itself. Here I report that the ECM receptor dystroglycan is necessary for laminin enhancement of filopodial formation, process outgrowth, and process branching in differentiating oligodendroglia. During early oligodendroglial differentiation, the disruption of …

Generalized Anxiety Disorder: Examination Of Fear Generalization And Anticipation Of Affective Stimuli, Tsafrir Greenberg

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Despite increasing interest in generalized anxiety disorder (GAD) it remains one of the least studied anxiety disorders and little is known about its neurobiology. The aim of the current research study was to investigate the neural basis of GAD from two perspectives: fear generalization and anticipation of affective outcomes. Thirty-two women with GAD (17 with and 15 without comorbid major depression disorder) and 25 healthy women underwent functional magnetic resonance imaging (fMRI) while completing two tasks: a fear generalization task in which participants were presented with a conditioned stimulus (CS) that co-terminates with a brief electric shock, and generalization stimuli …

English Identity In The Writings Of John Milton, Hannah E. Ryan

Honors Theses

John Milton is an essential writer to the English canon. Understanding his life and thought is necessary to understanding his corpus. This thesis will examine Milton’s nationalism in several major and minor poems as well as in some of Milton’s prose. It will argue that Milton’s nationalism is difficult to trace chronologically, but that education is always essential to Milton’s national vision of England.

A Comparison Of Testosterone With Prostate Specific Antigen And Prostatic Acid Phosphatase For The Serodiagnosis Of Prostate Cancer In Adult Males, Annie Chu

Honors Theses

Prostate cancer is the second most common cause of death from cancer in men. The American Cancer Society has estimated that there were 240,890 newly diagnosed cases in 2011 and 33,720 deaths from prostate cancer. Diagnosis of this disease has traditionally been done by measuring prostate specific antigen (PSA) levels through sero-chemical testing. The purpose of this study is to compare serum testosterone levels to PSA levels and Prostatic Acid Phosphatase (PAP) levels in the search for new and more accurate technology. This study shows that testosterone was not efficient in correctly diagnosing those with prostate cancer. It had a …

A National Security Staff For The 21st Century, Jack A. Lecuyer Dr.

Books, Monographs & Collaborative Studies

View the Executive Summary

Our legacy 1947/1989 national security system is unsuited for the dynamic and complex global security environment that has developed since the end of the Cold War. Over time, the National Security Council has evolved from the very limited advisory group initially imagined by President Truman to that of a vast network of interagency groups that were developed since 1989. These interagency groups view themselves as deeply involved in integrating policy development, crisis management, and staffing for the President. However, the National Security Staff (NSS) and the national security system are relics of the industrial age—vertical stovepipes—in …

Altered Hemodynamics, Endothelial Function, And Protein Expression Occur With Aortic Coarctation And Persist After Repair, Arjun Menon, Thomas J. Eddinger, Hongfeng Wang, David C. Wendell, Jeffrey M. Toth, John F. Ladisa

Biomedical Engineering Faculty Research and Publications

Coarctation of the aorta (CoA) is associated with substantial morbidity despite treatment. Mechanically induced structural and functional vascular changes are implicated; however, their relationship with smooth muscle (SM) phenotypic expression is not fully understood. Using a clinically representative rabbit model of CoA and correction, we quantified mechanical alterations from a 20-mmHg blood pressure (BP) gradient in the thoracic aorta and related the expression of key SM contractile and focal adhesion proteins with remodeling, relaxation, and stiffness. Systolic and mean BP were elevated for CoA rabbits compared with controls leading to remodeling, stiffening, an altered force response, and endothelial dysfunction both …

Differential Lung Uptake Of 99mtc-Hexamethylpropyleneamine Oxime And 99mtc-Duramycin In The Chronic Hyperoxia Rat Model, Anne V. Clough, Said H. Audi, Steven Thomas Haworth, David L. Roerig

Biomedical Engineering Faculty Research and Publications

Noninvasive radionuclide imaging has the potential to identify and assess mechanisms involved in particular stages of lung injury that occur with acute respiratory distress syndrome, for example. Lung uptake of ^99mTc-hexamethylpropyleneamine oxime (HMPAO) is reported to be partially dependent on the redox status of the lung tissue whereas ^99mTc-duramycin, a new marker of cell injury, senses cell death via apoptosis or necrosis. Thus, we investigated changes in lung uptake of these agents in rats exposed to hyperoxia for prolonged periods, a common model of acute lung injury. Methods: Male Sprague–Dawley rats were preexposed to either normoxia (21% O …

Making Disciples Through Evangelism: A Plan For The Evangelist Who Only Has One Chance At A New Convert, Richard Hertless

Doctoral Dissertations and Projects

Making disciples is an integral part of being a Christian. God has called some to be Evangelists (Ephesians 4:11). The rationale of the project is the need to fulfill the Great Commission's command of "making disciples." The value of this project is the plan that is developed to ensure that new converts will be placed with a disciple to confirm his or her Christian growth. This project will take the reader through a step-by-step plan to prepare, conduct and follow-up on an evangelism event to ensure that the Great Commission is fulfilled for the new convert to successfully walk in …

Acoustic Scale From The Angular Power Spectra Of Sdss-Iii Dr8 Photometric Luminous Galaxies, Hee-Jong Seo, Shirley Ho, Martin White, Antonio J. Cuesta, Ashley J. Ross, Shun Saito, For Full List Of Authors, See Publisher's Website.

Physics Faculty Research & Creative Works

We measure the acoustic scale from the angular power spectra of the Sloan Digital Sky Survey III (SDSS-III) Data Release 8 imaging catalog that includes 872, 921 galaxies over ~10,000 deg² between 0.45 < z < 0.65. The extensive spectroscopic training set of the Baryon Oscillation Spectroscopic Survey luminous galaxies allows precise estimates of the true redshift distributions of galaxies in our imaging catalog. Utilizing the redshift distribution information, we build templates and fit to the power spectra of the data, which are measured in our companion paper, to derive the location of Baryon acoustic oscillations (BAOs) while marginalizing over many free parameters to exclude nearly all of the non-BAO signal. We derive the ratio of the angular diameter distance to the sound horizon scale D_A(z)/r_s = 9.212^+0.416_-0.404 at z = 0.54, and therefore DA (z) = 1411 ± 65 Mpc at z = 0.54; the result is fairly independent of assumptions on the underlying cosmology. Our measurement of angular diameter distance D_A(z) is 1.4σ higher than what is expected for the concordance ΛCDM, in accordance to the trend of other spectroscopic BAO measurements for …

Clustering Of Sloan Digital Sky Survey Iii Photometric Luminous Galaxies: The Measurement, Systematics, And Cosmological Implications, Shirley Ho, Antonio J. Cuesta, Hee-Jong Seo, Roland De Putter, Ashley J. Ross, Martin White, Nikhil Padmanabhan, Shun Saito, For Full List Of Authors, See Publisher's Website.

Physics Faculty Research & Creative Works

The Sloan Digital Sky Survey (SDSS) surveyed 14,555 deg², and delivered over a trillion pixels of imaging data. We present a study of galaxy clustering using 900,000 luminous galaxies with photometric redshifts, spanning between z = 0.45 and z = 0.65, constructed from the SDSS using methods described in Ross et al. This data set spans 11,000 deg² and probes a volume of 3 h^-3 Gpc³, making it the largest volume ever used for galaxy clustering measurements. We describe in detail the construction of the survey window function and various systematics affecting our measurement. …

Rounding Of A First-Order Quantum Phase Transition To A Strong-Coupling Critical Point, Fawaz Hrahsheh, Jose A. Hoyos, Thomas Vojta

Physics Faculty Research & Creative Works

We investigate the effects of quenched disorder on first-order quantum phase transitions on the example of the N-color quantum Ashkin-Teller model. By means of a strong-disorder renormalization group, we demonstrate that quenched disorder rounds the first-order quantum phase transition to a continuous one for both weak and strong coupling between the colors. In the strong-coupling case, we find a distinct type of infinite-randomness critical point characterized by additional internal degrees of freedom. We investigate its critical properties in detail and find stronger thermodynamic singularities than in the random transverse field Ising chain. We also discuss the implications for higher spatial …

Disordered Bosons In One Dimension: From Weak- To Strong-Randomness Criticality, Fawaz Hrahsheh, Thomas Vojta

Physics Faculty Research & Creative Works

We investigate the superfluid-insulator quantum phase transition of one-dimensional bosons with off-diagonal disorder by means of large-scale Monte Carlo simulations. For weak disorder, we find the transition to be in the same universality class as the superfluid-Mott insulator transition of the clean system. The nature of the transition changes for stronger disorder. Beyond a critical disorder strength, we find nonuniversal, disorder-dependent critical behavior. We compare our results to recent perturbative and strong-disorder renormalization group predictions. We also discuss experimental implications as well as extensions of our results to other systems.

The Relationship Between Foundations And Principles In Ip Law, Robert P. Merges

San Diego Law Review

In my book Justifying Intellectual Property (JIP), I wrote about what I call the “foundations” of the field of intellectual property (IP) law. I tried to distinguish between a foundational level of discourse and another level, the level of basic principles. In the San Diego conference at which my book was discussed—and in several other settings as well—the most frequent and persistent line of questioning about my book centered on the relationship between these two levels. That is what this brief Article is about.
