Sex Worker Rights Organizing As Social Movement Unionism: Responding To The Criminalization Of Work, Crystal A. Jackson

UNLV Theses, Dissertations, Professional Papers, and Capstones

In a post-industrial, de-regulated economy, worker organizing is changing shape and function. While much research has focused on the decline of U.S. union organizing and the difficulty of organizing today's workers, a growing body of research on social movement unionism interrogates how "un-organizable" and "non-traditional" workers like day laborers and domestic workers are organizing. Yet sex worker activism in the U.S. is little studied, which is interesting given sex workers unique position as criminalized and contingent workers. Based on a two year ethnographic study from 2010 to 2012 of a national sex worker rights organization, the Desiree Alliance (DA), I …

A Gaming Application Of The Negative Hypergeometric Distribution, Steven Norman Jones

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Negative Hypergeometric distribution represents waiting times when drawing from a finite sample without replacement. It is analogous to the negative binomial, which models the distribution of waiting times when drawing with replacement. Even though the Negative Hypergeometric has applications it is typically omitted from textbooks on probability and statistics and is not generally known. The main purpose of this thesis is to derive expressions for the mean and variance of a new application of the Negative Hypergeometric to gaming and gambling. Other applications are described as well.

The Distributed Application Debugger, Michael Quinn Jones

UNLV Theses, Dissertations, Professional Papers, and Capstones

Developing parallel programs which run on distributed computer clusters introduces additional challenges to those present in traditional sequential programs. Debugging parallel programs requires not only inspecting the sequential code executing on each node but also tracking the flow of messages being passed between them in order to infer where the source of a bug actually lies.

This thesis focuses on a debugging too called The Distributed Application Debugger which targets a popular distributed C programming library called MPI (Message Passing Interface). The tool is composed of multiple components which run together seamlessly to provide its users an effective way to …

Design And Testing Of Novel Mouthguard With Intermediate Nitinol And Foam Layers, Adam Kessler

UNLV Theses, Dissertations, Professional Papers, and Capstones

It is the aim of this study to investigate a novel mouthguard design that incorporates the use of a nickel-titanium (Nitinol) layer and thin foam layer in addition to EVA layers. It is thought that the Nitinol layer can distribute the force of an impact and that the thin foam layer may absorb this distributed force better than a solid EVA mouthguard of the same thickness. Rectangular, flat coupons representative of several mouthguard configurations were constructed for testing using an instrumented drop-weight impact tower. The coupon configurations include a control made of laminated EVA, a group of laminated EVA and …

Scheduling Jobs On Two Uniform Parallel Machines To Minimize The Makespan, Sandhya Kodimala

UNLV Theses, Dissertations, Professional Papers, and Capstones

The problem of scheduling n independent jobs on m uniform parallel machines such that the total completion time is minimized is a NP-Hard problem. We propose several heuristic-based online algorithms for machines with different speeds called Q₂||C_max. To show the efficiency of the proposed online algorithms, we compute the optimal solution for Q₂||C_max using pseudo-polynomial algorithms based on dynamic programming method. The pseudo-polynomial algorithm has time complexity O (n T²) and can be run on reasonable time for small number of jobs and small processing times. This optimal offline algorithm is …

James Joyce And Post-Imperial Bildung: Influences On Salman Rushdie, Tayeb Salih, And Tsitsi Dangarembga, Robert Michael Kirschen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Joyce's "A Portrait of the Artist as a Young Man" functions as an axis around which writers from former British colonies--Salman Rushdie (India), Tayeb Salih (Sudan), and Tsitsi Dangarembga (Zimbabwe)--construct their own Bildungsromans. This nodal point is possible because Joyce's Bildungsroman represents a unique rendering of the genre which has proven useful for narratives of growth and development in newly independent nations. This dissertation focuses on a single narrative paradigm which acts as a common thread among the four authors. In each text (Rushdie's "Midnight's Children", Salih's "Season of Migration to the North", and Dangarembga's "Nervous Conditions"), the use of …

Generalizations Of Pascal's Triangle: A Construction Based Approach, Michael Anton Kuhlmann

UNLV Theses, Dissertations, Professional Papers, and Capstones

The study of this paper is based on current generalizations of Pascal's Triangle, both the expansion of the polynomial of one variable and the multivariate case. Our goal is to establish relationships between these generalizations, and to use the properties of the generalizations to create a new type of generalization for the multivariate case that can be represented in the third dimension.

In the first part of this paper we look at Pascal's original Triangle with properties and classical applications. We then look at contemporary extensions of the triangle to coefficient arrays for polynomials of two forms. The first of …

Paul Moravec: Polystylism In Cool Fire (2001), Jennifer Kuk-Bonora

UNLV Theses, Dissertations, Professional Papers, and Capstones

The goal of this document is to provide a structural and stylistic analysis of Paul Moravec's chamber piece, Cool Fire (2001) within the context of Alfred Schnittke's polystylism. Fundamental polystylism is the use of two or more music styles within one composition and focuses on a more evolved portrayal of the style when, "there are no longer any direct quotations, but rather a certain element which indicates a `genetic refill' of memories." Techniques from Impressionism, Jazz, Baroque and Classical styles are utilized in Cool Fire.

The method of analysis will follow Jan La Rue's Guidelines for Style Analysis to better …

Development And Validation Of The Biophilic Attitudes Inventory (Bai), Lawrence Letourneau

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study investigated the viability of an instrument called the Biophilic Attitudes Inventory (BAI), a pen-and-paper instrument intended to measure attitudes toward nature that, according to naturalist Edward O. Wilson, are rooted in an innate predisposition that humans possess to connect with other forms of life. Utilizing confirmatory factor analysis (CFA), two models were tested (n=334)--a seven-factor model that reflected Stephen Kellert's biophilia typology and a more parsimonious two-factor model. However, neither model proved viable in terms of construct validity. As a result, a new model with four factors was developed via exploratory factor analysis (EFA). A subsequent CFA revealed …

Decoding Skills Of Middle-School Students With Autism: An Evaluation Of The Nonverbal Reading Approach, Patrick Allen Leytham

UNLV Theses, Dissertations, Professional Papers, and Capstones

Students diagnosed with autism demonstrate a deficit in communication skills, which affects their literacy skills. Federal legislation mandates that students with disabilities receive a free appropriate public education, be taught how to read, and have access to the general education curriculum. Students with autism are being included more in the general education classroom. Prior literacy instruction for students with moderate to severe forms of disabilities has shown promising results. The whole language approach to teaching students with autism how to read has been researched extensively, particularly in the area of sight-word identification. One major limitation to this approach, however, is …

For this research a tube type IPMC was investigated. This IPMC has a circular cross section with four separate electrodes on its surface and a hole through the middle. The four electrodes allow for biaxial bending and accurate control of the tip location. One of the main advantages of using this type …

Strange Little Vehicles, Andrew Merecicky

UNLV Theses, Dissertations, Professional Papers, and Capstones

It isn't an exploration in or an experiment regarding. It is a praxis, as a commute is the opposite of an adventure. As le chat regarde le poisson. As when one looks at anything, it becomes strange. That is, a thing (a thought, a feeling, Gertrude Stein's "piece of coffee") once considered becomes little and different. It is the world that is large and alike. It is ultimately the similarity, the recognition of which we, who feel small and unique in the grand scheme, find terrifying. Language is always, as Lyn Hejinian wrote, social; it is a vehicle.

As I …

Understanding Effects Of Changes In Land Use, Environmental Parameters, Habitat Characteristics On The Great Basin Aquatic Invertebrates Using Ecological Stoichiometric Theory, Knut Mehler

UNLV Theses, Dissertations, Professional Papers, and Capstones

Many freshwater ecosystems in the Great Basin have undergone dramatic alteration over the past decades due to groundwater withdrawal, water diversion and changes in land use. These changes have affected benthic food web dynamics by altering the availability of chemical key elements for primary and secondary producers, by loss of biodiversity and extinction of endemic species. However, only few studies are available that addresses the link between changes in land use, habitat characteristics and its effects on benthic macroinvertebrates (BMI) communities comprehensively and little attention has been given to integrating physiochemical aspects to link ecosystem functions.

This dissertation analyzes the …

Investigating The Feasibility Of Growing Algae For Fuel In Southern Nevada, Faegheh Moazeni

UNLV Theses, Dissertations, Professional Papers, and Capstones

Microalgae capable of growing in waste are adequate to be mass-cultivated for biodiesel, avoiding fertilizers and clean water, two obstacles to sustainability of the feedstock production. This study replaces fertilizers and clean water with waste products. The investigated wastes include (1) the liquid fraction of sewage after solids and particles are removed, known as centrate, and (2) algal biomass residue, i.e. the algae remaining at the end of the lipids extraction process at biofuel plants. These wastes contain sufficient amount of nitrogen and phosphorus required for algal growth. This study proposes a system in which centrate would be used as …

School Psychologists' Perspectives Of Response-To-Intervention: Training, Practices, And Implementation, Michelle Nathan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Specific learning disabilities currently account for the 39 percent of the 6.6 million students who receive special education services in a public school setting (Aud, Husser, Planty, Snyder, Bianco, Fox, et al, 2010). The current federal definition of what constitutes a specific learning disability states that school districts are allowed to use either the aptitude-achievement discrepancy model or alternative assessment methods, thereby legitimizing the use of response-to-intervention (RTI) (Dykeman, 2006).

The current study provided an investigation into the current training and practices of school psychologists and the barriers they face when implementing RTI within a school setting. The purpose of …

Additive Effects Of An External Focus And Enhanced Expectancy In Learning A Motor Skill, Luigi Antonio Pascua

UNLV Theses, Dissertations, Professional Papers, and Capstones

An external focus of attention in has been shown to produce better performance in practice and retention of a motor skill when compared to an internal focus or control conditions in which no attentional focus cues are given to the learner (for a review, see Wulf, 2012). Enhancing learner expectancy (e.g., via positive feedback) has also been shown to improve learning (e.g., Lewthwaite & Wulf, 2010). This study sought to investigate whether combining the positive effects of an external focus of attention with an enhanced learner expectancy (through positive social-comparative feedback) would enhance learning relative to either variable alone or …

The Effects Of Starvation Selection On Drosophila Melanogaster Life History And Development, Lauren A. Reynolds

UNLV Theses, Dissertations, Professional Papers, and Capstones

In nature, animals may endure periods of famine to complete their life cycles. Starvation stress will increase in populations as climates around the world change. To predict how populations may respond to such a stress, laboratory experimentation becomes essential. The evolutionary process of adaptation, its innovations and their trade-offs, can be studied in populations experiencing starvation stress. For this purpose outbred populations ofDrosophila melanogasterwere selected for starvation resistance in the laboratory.

After 60+ generations of starvation selection the starvation-selected flies have gone from surviving 2-3 days without food to 12-14 days without food. How this amazing feat of resistance is …

The Effects Of Chronic Calcium Dysregulation On Behavioral And Pathological Features Of Alzheimer's Disease, Jonathan Sabbagh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Alzheimer's disease (AD) is a progressive neurodegenerative disorder whose etiology is unknown. Recent studies have implicated alterations in calcium homeostasis as a pathogenic contributor to AD. Calcium dysregulation has been observed in aged and AD brains, an event which could potentially facilitate the development of multiple pathologies observed in AD. Specifically, disrupting intracellular calcium levels in vitro has been demonstrated to increase amyloid-beta (Aβ) production, tau phosphorylation, and neuronal loss. However, there is a paucity of data on the behavioral and biochemical consequences of chronic in vivo perturbation of calcium homeostasis. In a series of experiments designed to evaluate the …
