Composite Of Complexity: Manifestations Of Whiteness And Class Among Las Vegas Italian Americans, Danielle Nicole Axt

UNLV Theses, Dissertations, Professional Papers, and Capstones

Conventional terminology and conventional boundaries, in regard to ethnicity, are no longer applicable to the ever shifting population of the United States. In specific, the various degrees of White ethnic identity does not easily transition into convenient all encompassing categories such as Caucasian or more simply, White. Whiteness studies have been at the forefront of this critique, most recently asserting that White ethnic identity is heavily influenced by context. However, although many studies are now recognizing the impact of multiple layers of White ethnic identity (along the lines of gender, locale, socioeconomic level etc.) many still neglect to identify a …

Analyzing The Impact Of Reactive Transport On The Repository Performance Of Triso Fuel, Gregory Schmidt

UNLV Theses, Dissertations, Professional Papers, and Capstones

One of the largest determiners of the amount of electricity generated by current nuclear reactors is the efficiency of the thermodynamic cycle used for power generation. Current light water reactors (LWR) have an efficiency of 35% or less for the conversion of heat energy generated by the reactor to electrical energy. If this efficiency could be improved, more power could be generated from equivalent volumes of nuclear fuel. One method of improving this efficiency is to use a coolant flow that operates at a much higher temperature for electricity production. A reactor design that is currently proposed to take advantage …

Evaluating The Energy And Carbon Footprint Of Water Conveyance System And Future Water Supply Options For Las Vegas, Nevada, Eleeja Shrestha

UNLV Theses, Dissertations, Professional Papers, and Capstones

Water production requires the use of energy to transport water from distant locations, pump groundwater from deep aquifers and treat water to meet stringent drinking water and wastewater regulations. Energy production based on its source involves the emission of greenhouse gases also known as carbon footprint, which is the leading cause of global warming and climate change. Because of growing concerns of global warming due to these emissions, water providers are required to analyze the energy and associated carbon footprint of existing water production facilities and future water supply options. A system dynamics model is developed to estimate the energy …

Physiological Implications Of Natural Versus Induced Arousal From Torpor, Jenifer C. Utz

UNLV Theses, Dissertations, Professional Papers, and Capstones

During the hibernation season, animals oscillate between periods of torpor and periods of interbout arousal (IBA). During torpor, body temperature is often near 0° C and metabolism is severely depressed. Oxygen consumption, a proxy for aerobic metabolism, may fall to 1% of active values. Many physiological processes including cardiovascular, respiratory, and cellular functions nearly cease. During the IBA, euthermic body temperature is restored and most systemic and cellular processes function at fully active levels. The transition period between these two physiologically dissimilar states is called arousal.

The rate of rewarming (RRW) during arousal was previously expected to progressively increase until …

The Relationship Between Fitness Level, Gender, And The Percentage Of Vo2 Max At Crossover, Christina Louise Pettigrew

UNLV Theses, Dissertations, Professional Papers, and Capstones

The “crossover” concept is a means of understanding fuel utilization over a range of exercise intensities. According to this concept, certain biochemical adaptations occur in a fit individual allowing for an increase in lipid oxidation. The present study examined whether there was a relationship between fitness level, gender, and the percentage of maximum aerobic capacity (VO2 max) at crossover. Twenty-five subjects age 18-40 participated in this study. Subjects were divided in half based on their fitness level. After completing a graded exercise test to exhaustion, the crossover point for each subject was determined relative to their VO2 max. A 2x2 …

The Determinants Of Colorectal Cancer Survival Disparities In Nevada, Lucas N. Wassira

UNLV Theses, Dissertations, Professional Papers, and Capstones

Different population groups across Nevada and throughout the United States suffer disproportionately from colorectal cancer and its after-effects. Overcoming cancer health disparities is important for lessening the burden of cancer. There has been an overall decline in the incidence of and mortality from colorectal cancer (CRC). This is likely due, in part, to the increasing use of screening procedures such as Fecal Occult Blood Test (FOBT) and/or endoscopy, which can reduce the risk of CRC mortality by fifty percent. Nevertheless, screening procedures are routinely used by only fifty percent of Americans aged fifty years and older. Despite overall mortality decreasing …

Rare Earth Element Transport In The Yucca Mountain Region, Liqiong Zhang

UNLV Theses, Dissertations, Professional Papers, and Capstones

In sync with environmental pollution of solutes in nature, from source, process to consequence, geochemical processes (leaching and sorption) and hydraulic transportation of the rare earth elements (REEs) have been investigated at Yucca Mountain (YM), Nevada. This research includes the leaching behavior of trace elements (including REEs) from aquifer rocks, the surface complexation reactions of REEs in synthetic groundwater, and transportation of reactive REEs in the local-scale groundwater system of YM. This dissertation includes three projects. These studies indicate that surface complexation reactions may retard the transportation of REEs along groundwater paths in YM, which suggests a similar behavior of …

Measurement System For High Pressure Characterizations Of Materials, Matthew K. Jacobsen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Thermoelectric materials have long been investigated for possible use as power sources. This application was recently put to use in the Voyager space program, powering the deep space probes. Despite the usefulness of these materials, the use of pressure to investigate the material properties has only recently become interesting. As such, the work in this document was to developing a system for concurrently measuring the necessary properties. This system is capable of measuring the electrical resistivity, thermal conductivity, and Seebeck coefficient in the pressure range from 0 - 10 GPa. The results for zinc, almandine garnet, and nickel are presented …

Structures On A K3 Surface, Nathan P. Rowe

UNLV Theses, Dissertations, Professional Papers, and Capstones

In the first part of this paper, we examine properties of K3 surfaces of the form:

(x2 + 1)(y2 + 1)(z2 + 1) + Axyz − 2 = 0

We show the surface has Picard number q " 12 by finding 12 curves whose equivalence classes are linearly independent. These curves have self intersection −2. We find the lattice representations of the single-coordinate swapping automorphisms in x, y, and z. We show that we have enough of the Lattice to make accurate predictions of polynomial degree growth under the automorphisms. We describe these automorphisms in terms of operations on elliptic …

Classification Algorithms For Genomic Microarray, Rakesh Choudary Malepati

UNLV Theses, Dissertations, Professional Papers, and Capstones

The advent of new technologies like DNA micro-arrays provides scientists the ability to gather important information such as the expression levels of almost all the genes within a cell. As the collected data is huge, it is always necessary to use analytical methods to extract important information which can be useful in biological and medical applications. One of such applications is presented in (Van‟t Veer LJ 2002), where the authors used the gene expression values obtained from micro-arrays of breast cancer cells to predict the outcome of the disease. The prediction is based on a supervised classification. While the idea …

Bordered Identities: Class, Ethnicity, And Transnational Social Networks, Rayette Ellen Martin

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis looks at the bordered identities of middle class second generation Mexican Americans in Las Vegas, Nevada. Through an analysis of the borderlands or gray spaces that occur at the intersections of class practices, transnational relationships and ethnic identities, participants’ bordered identities were found to be reinforced, contested, and generally negotiated. Participants’ identities are flexible; their expressed identities change in relation to context or situation. In the United States, Mexicans and Latinos more generally have been subjected to racial and ethnic oppression since the Mexican American war ended in 1848.This long history of discrimination has maintained perceptions that all …

From ‘Baggage’ To Not ‘Non-Persons’: Levy V. Louisiana And The Struggle For Equal Rights For ‘Illegitimate’ Children, Sherrie Anne Bakelar

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study focuses on "illegitimate" children, who are more visible
than other children within the historical record because of the many laws
related to their existence. By examining this group of children, it is
possible to improve upon the framework that shapes our understanding
of childhood and provide a starting point for future studies that will
continue to illuminate children's history. Although illegitimacy laws are
as ancient as Western civilization, the key moment for the United States'
laws related to nonmarital children came in the spring of 1968 and the
pivotal decision of Levy v. Louisiana, 391 U.S. 68 (1968). …

Out of the various metal nanoparticles that have been investigated, the most promising are that made of gold and silver. Metal nananoparticles of gold and silver show strong Raman enhancement in the visible spectral region, making …

Reconstructing Species Responses To Past Climatic Changes Using Niche Modeling And Genetic Data, Tereza Jezkova

UNLV Theses, Dissertations, Professional Papers, and Capstones

Glacial – interglacial cycles have a pronounced impact on species distributions and genetic structure. Many species shift their distributions to lower latitudes and altitudes during the colder glacial periods and expand northwards and up the elevation during warmer interglacial periods. Some species however are capable of adapting to changing environment which allows them to persist in place despite climatic changes. I explored how climatic changes after the last glacial maximum (LGM) effected two species inhabiting the deserts of western North America: one mammal (Chisel-toothed Kangaroo Rat, Dipodomys microps) and one reptile (Desert Horned Lizard, Phrynosoma platyrhinos). I used …

Must Pay Now, David C. Perkins

UNLV Theses, Dissertations, Professional Papers, and Capstones

These poems attempt to stand amidst the towering shadows of Enlightenment. One of these pillars involves the newfound land from a collective western European vantage and these lands are called the Americas. This space is where these poems are located. They suckle at the monolithic breasts of Enlightened Romance as did Romulus and Remus to the She-Wolf. The poems in their own originality engage with writers such as Jonathan Edwards, Alice Notley, Susan Howe, Frank O’Hara, William Carlos Williams, Walt Whitman, Christina Rossetti, William Blake, and John Cage. If there ever was such a thread in tradition, these people might …

Minimizing Base Column Demands In Multi-Story Buckling Restrained Braced Frames Using Genetic Algorithms, Christopher Hiroshi Yeates

Theses and Dissertations

Most structural optimization procedures focus on minimizing the total volume of steel in an attempt to reduce overall costs. However, many other factors can have an effect on the overall cost of a structure. Base column demands in particular, can affect base plate sizes, anchorage, and foundation design. Researchers have found that present methods for estimating column demands are too conservative. Nonlinear time history analyzes were conducted on buckling-restrained braced frames of six heights. Optimized results were found considering three ductility constraints and two optimization objectives. The two optimization objectives were minimized total brace area and minimized base column demands. …

Losing Our Way?: Declining Outdoor Opportunities For Learning For Children Aged Between 2 And 11, Sj Waite

Plymouth Institute of Education

This paper draws on three related empirical studies in the South West of England: a survey of outdoor experiential learning opportunities, examining attitudes, practice and aspirations of practitioners and children in educational and care settings for children between 2–11 years within a rural county; a follow-up series of five case studies; and an ongoing ESRC funded study of outdoor learning practice across the transition between Foundation Stage and Year 1 in two city-based schools. It charts the journey of outdoor learning from early years to primary practice in England and indicates the ‘navigational tools’ used by practitioners and the possibly …

Judicial Case Management: Caught In The Crossfire, Steven S. Gensler

Duke Law Journal

For thirty years, the Federal Rules of Civil Procedure have relied on active Judicial case management to combat undue cost and delay The complaints about cost and delay have not gone away, but few blame the case-management rules for that Indeed, lawyers continue to view active judicial case management as one of the best ways of reducing cost and delay, and most of the reforms being urged today seek even greater Judicial case management for that reason But some think the rulemakers took a wrong turn thirty years ago and that each round of rulemaking that places more reliance on …

Selling Knowledge: A Sociological Analysis Of Attorney Advertisement In Las Vegas, Giselle Velasquez

UNLV Theses, Dissertations, Professional Papers, and Capstones

I analyze how Las Vegas attorneys represent themselves, their associates and clients in televised law firm commercials. I use attorney commercials as a case to explore cultural beliefs in media representations. Using an inductive method, I analyze the textual, visual, and aural symbols that appear most frequently in television commercials to interpret how law firm advertisements convey themes of attorney expertise, knowledge, ethnic and gender stereotyping. I introduce this study with a historical evaluation of the rise of advertisement in the United States. I continue discussing how the media is an important realm of discourse that affects people's identity. Using …

Donepezil And Galanin Interactions In An Animal Model Of Alzheimer’S Disease, Jonathan J. Sabbagh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Alzheimer's disease (AD) is a neurodegenerative disorder marked by a progressive loss of cognitive function. One of the neurobiological hallmarks of AD is a progressive loss of cholinergic neurons and a decrease in the amount of acetylcholine in the brain. Pharmacological therapies have targeted the cholinergic system, specifically first-line, palliative treatment using acetylcholinesterase (AChE) inhibitors, such as donepezil. Donepezil has been shown to increase cholinergic tone and ameliorate some of the cognitive deficits in AD patients. Galanin, a neuropeptide that inhibits the evoked release of several neurotransmitters including acetylcholine as well as modulates seveal intracellular cascades, is overexpressed in AD …

The Multiple-Choice Concept Map (Mccm): An Interactive Computer-Based Assessment Method, Ioan C. Sas

UNLV Theses, Dissertations, Professional Papers, and Capstones

This research attempted to bridge the gap between cognitive psychology and educational measurement (Mislevy, 2008; Leighton & Gierl, 2007; Nichols, 1994; Messick, 1989; Snow & Lohman, 1989) by using cognitive theories from working memory (Baddeley, 1986; Miyake & Shah, 1999; Grimley & Banner, 2008), multimedia learning (Mayer, 2001), and cognitive load (Chandler and Sweller, 1991, 1992; Cerpa, Chandler, & Sweller., 1996) to identify potential design weaknesses of traditional select-and-fill-in (SAFI) concept map assessment and then to guide the design of the new and improved multiple-choice concept map (MCCM) assessment method. The primary objective of this study was to evaluate the …

The Political Branches And The Law Of Nations, Bradford R. Clark, Anthony J. Bellia Jr.

Journal Articles

In the late eighteenth and early nineteenth centuries, the U.S. Supreme Court went out of its way to follow background rules of the law of nations, particularly the law of state-state relations. As we have recently argued, the Court followed the law of nations because adherence to such law preserved the constitutional prerogatives of the political branches to conduct foreign relations and decide momentous questions of war and peace. Although we focused primarily on the extent to which the Constitution obligated courts to follow the law of nations in the early republic, the explanation we offered rested on an important, …

The Experiences Of Expatriate Teachers In International Schools: Five Ethnographic Case Studies, James S. Anderson Edd

Dissertations

An increasingly global economy has produced a growing demand for teachers to work in international schools. However, data about teachers who elect to move abroad and work in international settings are limited. The lack of research in this area is surprising, given the relatively large number of expatriate teachers who work in international schools. The purpose of this study was to gain a better understanding of how expatriate teachers perceive their experiences in international schools and the role that these perceptions may play in their decisions to continue at a school or to seek other employment. In order to explore …

Politics And Civil Procedure Rulemaking: Reflections On Experience, Paul D. Carrington

Duke Law Journal

This Article is a reflection on personal experience as well as an account of what has happened to the Federal Rules of Civil Procedure in the most recent quarter century It observes that the Supreme Court of the United States has assigned to itself a role in making procedural law inconsistent with the Rules Enabling Act of 1934 or any more-recent utterance of Congress This procedural law made by the Court is responsive to the desire of business interests to weaken the ability of citizens to enforce laws enacted to protect them from business misconduct The Article concludes with the …

The Short-Term Influence Of Free Digital Versions Of Books On Print Sales, John L. Hilton Iii, David Wiley

Faculty Publications

Increasingly, authors and publishers are freely distributing their books electronically to increase the visibility of their work. A vital question for those with a commercial stake in selling books is, “What happens to book sales if digital versions are given away?” We used BookScan sales data for four categories of books (a total of 41 books) for which we could identify the date when the free digital versions of the books were made available to determine whether the free version affected print sales. We analyzed the data on book sales for the eight weeks before and after the free versions …

Many complicated phenomena are associated with transient stages during the continuous casting process, especially inside the casting mold cavity. a deep understanding of the phenomena and optimized control over the process ensure the high-quality product and low costs. This work presents a three-dimensional numerical simulation of transient fluid flow phenomena during steel continuous casting. in the Part II, the process of casting speed change (increase or decrease), temperature fluctuation, and steel grade mixing in a slab mold were investigated. the phenomena, such as flow pattern, inclusion removal fraction, temperature variation, top surface profile, and steel transportation, were addressed to evaluate …

An Investigation Of High School Dual Enrollment Participation And Allied Health Program Enrollment In A South Texas University, Martina Flores

Theses and Dissertations - UTB/UTPA

The shortage of allied health professionals has caught the attention of legislators and higher education institution administrators. The current study used a concurrent embedded mixed method design to investigate factors that motivated students to participate in health science technology (HST) dual enrollment courses while still in high school. It sought to identify the factors or variables students believed helped them be successful in the health science courses. Additionally, the quantitative portion of the study investigated academic achievement as a function of high school achievement (HSAch), high school performance (HSPerf), Aptitude (Apt), and ProActive measures taken by students. Two focus groups …

Memory-Keepers: An Ethnographic Look At Female Agency Among Italian-Americans, Hannah Burgwyn

Southern Anthropologist

(2010 Undergraduate Prize Winner.) While doing ethnographic research in Bayonne New Jersey among my extended Italian-American family over the summer of 2008 I began to see how deeply memories were valued within Italian-American communities. From fall 2008 to fall 2009, I continued my research in Asheville and Chapel Hill, North Carolina, also with people of Italian ancestry. These interviews supported the idea that memory aids in the construction and maintenance of Italian-American identity and works as a defining feature of female agency within the community. While studying gender roles of Italian-American women it became apparent that an important aspect of …

'You Have To Go North To Find The South': Situating Central Florida In The South For Birth Research, Erica Gibson

Southern Anthropologist

This paper reports on situating Central Florida as a part of the South for birth research among midwives, a physician, and their clients. A comparison is made between historical and modern beliefs about what is represented by Southern values and ideals, and how the women and birth practitioners in this study do or do not conform to those ideals.
