Volcanic Evolution Of The Southern Quinn Canyon Range: Implications For Regional Correlation Of Volcanic Units, Christina Emery

UNLV Theses, Dissertations, Professional Papers, and Capstones

The southern Quinn Canyon Range lies in an area of the Great Basin subjected to large-volume Oligocene-Miocene silicic volcanism and smaller volume basaltic volcanism during the Pliocene. Three major ash-flow tuff units were correlated in the southern Quinn Canyon Range (the Pahranagat Tuff, Clifford Spring Tuff, and the Cow Canyon Tuff) with regional units by utilizing U/Pb and 40 Ar/ 39Ar geochronology, geochemical correlation, and field mapping. Isotopic analysis suggests that basalt in the southern Quinn Canyon Range is part of the Death Valley-Pancake Range Basalt Zone and is similar to Reveille Range Episode 1 and 2 basalts.

Comparison And Simulation Of Salt-Ceramic Composites For Use In High Temperature Concentrated Solar Power, Lauren Michelle Fossile

UNLV Theses, Dissertations, Professional Papers, and Capstones

Due to the inherently intermittent nature of solar energy caused by cloud cover among other sources, thermal storage systems are needed to make solar energy more consistent. This same technology could be used to prolong the daily number of useful hours of solar energy power plants. Salt-ceramic materials are a relatively new prospect for heat storage, but have been researched mostly with magnesium oxide and several different carbonate salts. Salt ceramics are a phase change material where the salt changes phase inside the ceramic structure allowing for the system to use the sensible heat of both materials and the latent …

Anti-Germinants As A New Strategy To Prevent Clostridium Difficile Infections, Amber Janece Howerton

UNLV Theses, Dissertations, Professional Papers, and Capstones

Clostridium difficileinfections (CDI) have emerged as a leading cause of hospital-associated complications. CDI is the major cause of antibiotic-related cases of diarrhea and nearly all cases of pseudomembranous colitis. The infective form of C. difficileis the spore, a dormant and hardy structure that forms under stress. Germination of C. difficile spores into toxin producing bacteria in the GI tract of susceptible patients is the first step in CDI establishment. Patient susceptibility occurs with a disruption of the natural gut microbiota by broad-spectrum antibiotics. Antibiotic treatments usually resolve CDI but refractory cases are on the rise. Of great concern is the …

UNLV Theses, Dissertations, Professional Papers, and Capstones

"Archiving Joyce and Joyce's Archive: Ulysses, Finnegans Wake, and Copyright" investigates the ways in which James Joyce's Ulysses and Finnegans Wake incorporate archival institutions and archival modes such as gossip into its composition. For example, this work explores how both works, at times, present institutions such as the National Library of Ireland, and, at other times, enact archiving in its collection and preservation of historical personages relevant to Irish literature and history. Additionally, Joyce was involved in the construction of his own archive, and thereby becomes the curator of his own history as well as that of Ireland.

Importantly, this …

A Forensic Identification Utility To Create Facial Approximations Using Cone-Beam Computed Tomography Of 100 Hispanic Females: A Pilot Study, Behzad Nejat

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction:Estimation of facial soft tissue appearance from human skeletal remains is often necessary in forensic identification. This process has been referred to as facial reconstruction or facial approximation and is a branch of forensic facial anthropology. Original methods for facial approximation originated in nineteenth century Europe and consisted of artists shaping clay over skull models using average soft tissue depths measured in cadavers. The last two decades have introduced numerous computerized techniques that have digitized this process while attempting to accurately and objectively define the relationship between a skull and its overlying soft tissue. This pilot study describes a method …

Very little academic research has been conducted on the operating procedures of room service. This was an exploratory study that aimed at identifying the key principles and practices of room service operations in first-class and luxury hotels. This study used a mixed-method approach. Using content analysis on operating audits for room service from a range of hospitality companies, expert panel review, field testing, and analysis of variance …

Molecular Forensic Science Analysis Of Nuclear Materials, Dallas Reilly

UNLV Theses, Dissertations, Professional Papers, and Capstones

Concerns over the proliferation and instances of nuclear material in the environment have increased interest in the expansion of nuclear forensics analysis and attribution programs. A new related field, molecular forensic science (MFS) has helped meet this expansion by applying common scientific analyses to nuclear forensics scenarios. In this work, MFS was applied to three scenarios related to nuclear forensics analysis. In the first, uranium dioxide was synthesized and aged at four sets of static environmental conditions and studied for changes in chemical speciation. The second highlighted the importance of bulk versus particle characterizations by analyzing a heterogeneous industrially prepared …

Natural And Lignocellulose-Enriched Microbial Communities In Great Boiling Spring, Nv, Jessica Cole

UNLV Theses, Dissertations, Professional Papers, and Capstones

The natural microbial communities present in Great Boiling Spring were investigated and contrasted against those present after in situ enrichment with lignocellulose. High-throughput cultivation-independent DNA sequencing of the V8 region of the small subunit (SSU) rRNA gene generated a total of 274,119 quality-filtered pyrosequencing fragments. Twelve natural spring samples were analyzed, including four high-temperature water samples and eight sediment samples ranging from 87 - 62 °C. Eight lignocellulosic enrichments incubated in the spring sediment and water at two high-temperature sites were analyzed. The natural water communities were found to be extremely uneven but relatively constant throughout time. The natural sediment …

A Genetic, Transgenic, And Transcriptomic Analysis Of Larval Salivary Gland Physiology In Drosophila Melanogaster, Elana A. Paladino

UNLV Theses, Dissertations, Professional Papers, and Capstones

Cholesterol is the precursor to a unique class of lipophilic signaling molecules called steroid hormones that initiate the development of sexual characteristics, reactions to stress, and maintenance of metabolism, among many other functions. Although much progress has been made in understanding the function of these signaling hormones, we do not fully understand how a single steroid can cause many distinct, tissue-specific responses. Drosophila melanogaster is an effective model for understanding steroid hormone action because of its simplicity. The steroid molting hormone 20-hydroxyecdysone (hereafter, 20E) is the primary active steroid in Drosophila and mediates not only larval molts and the emergence …

UNLV Theses, Dissertations, Professional Papers, and Capstones

An integrated sedimentological study of detrital carbonates of the late Cambrian (Furongian) Hales Limestone in central Nevada was conducted in order to model facies distribution and controlling mechanisms of carbonate gravity-flow deposits. Seven closely-spaced sections and numerous traceable short sections were measured to investigate temporal and spatial changes of detrital carbonates within a high-resolution stratigraphic framework supported by biostratigraphic and carbon isotope chemostratigraphic constraints and by key physical surfaces. Polished slabs and thin section petrographic analysis were used to identify micro- and macro-scale textures and diagenesis.

Ten lithofacies are identified from the Hales Limestone. Lateral tracing of these facies reveals …

Theory Versus Practice: A Study Of Strategy Making In Five Public Mba Programs, Michael Alwyn Wilde

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study examined whether coercive, normative and mimetic isomorphic mechanisms contribute to the strategies public MBA programs develop and implement in their quests to differentiate themselves. An additional purpose was to examine whether influential environmental elements impact strategy development in ways that make these organizations more similar than different.

In depth interviews were conducted in an attempt to discover the experiences and perspectives of five current directors of MBA programs in public institutions of higher education. Purposeful sampling, in the form of convenience sampling within a clearly defined population, was used.

The findings suggest that none of the five MBA …

A Social Media Plan For The Ultimate Fighting Championship, Matthew Radmanovich

UNLV Theses, Dissertations, Professional Papers, and Capstones

Social media has revolutionized marketing and communication and has changed the way many organizations do business. In sports, it has facilitated fans getting closer to the action while allowing management to be strategic and more efficient with finite amount of resources. It has allowed sports to get in the business of “relationship marketing” (Gronroos, 2004). That is, when a game ends or a season comes to a close, social media allows for the fostering of long term relationships and continues to build a sense of community. The marriage of social media and relationship marketing cannot be overlooked. Whereas 30 years …

Leaving Tray Line Behind: A Proposal For Hybrid Hospital Foodservice, Christopher Connolly

UNLV Theses, Dissertations, Professional Papers, and Capstones

At Valley Hospital in Las Vegas, Nevada, the economic recession is as visible as anywhere else in the United States. A lack of paying patients equates to forced reductions in labor and increased productivity metric mandates. In the foodservice area, antiquated technology limits productivity in conducting tray line food service delivery. A new tray line system would need to be considerably faster while using less employees and moving parts to maximize efficiency, effectively doing much more with far less. There are two main systems of food service as part of the patient experience; tray line and room service. Both systems …

Search Engine Optimization: Best Practices For Google, Tucker Johnson

UNLV Theses, Dissertations, Professional Papers, and Capstones

The internet is a major delivery system of hotel reservations. Approximately 25% of all reservations made at a hotel come directly through the hotel’s website (Douglas, 2012). Another 11% of total reservations are booked online through online travel agent websites, or OTAs, such as Priceline.com or Expedia.com (Douglas, 2012). These additional reservations booked through the OTAs come at a cost to the hotel, however. Typical commissions for OTAs are approximately 25 % of a total booking (Sanders, 2012). In 2010, it was estimated that the commissions associated with these OTA bookings cost hoteliers 2.5 billion dollars (Douglas, 2012). Because of …

American Generation Y And The Hotel Of 2030, Brian Kelley

UNLV Theses, Dissertations, Professional Papers, and Capstones

Social Media Helps Small Businesses, Nicholas J. Oxborrow

UNLV Theses, Dissertations, Professional Papers, and Capstones

Beemer and Shook (2009) explain that developing customers one at a time is the only way. There are no short cuts to this. Traditionally, a small business would develop their relationships by going from door-to-door to raise awareness and grow their brand. How fast they achieved this depended on the budget and time available to their business. Traditionally, large businesses had the power of reaching their markets through huge advertising budget, which small companies could not match.

In today’s business environment, social media has become a new marketing tool that is available to all businesses, that instantly develops relationships with …

Several paradigms exist in evaluating the success of a UNESCO World Heritage site. This paper specifically examines how marketing strategies bolster sustainable tourism efforts.

The Pros And Cons Of Outsourcing, Angela Smith

UNLV Theses, Dissertations, Professional Papers, and Capstones

Outsourcing has become increasingly popular to the public since the mid-20th century and has become more controversial in the last decade. The United States economy has been under the microscope for the last 4 years due to an economic recession. Outsourcing has been a subject of interest that has been brought up numerous times by economists. Offshore outsourcing is the main type of outsourcing that is of concern in relation to the United States economy. This topic is highly debated because of the unemployment rate in America.
