UNLV Theses, Dissertations, Professional Papers, and Capstones

The economic indicators for the state of Nevada indicate a bleak financial future. The foreclosure rate of the Las Vegas Valley is five times the national average and the highest rate in the country (Hoak, 2010). Sales tax revenues continue spiraling down and fell by 6.6 percent in December 2009 from December 2008 (Garcia, 2010). State politicians face an estimated budget deficit of $3.5 billion. Local conditions are equally dire. The City of Las Vegas faces a budget shortfall of nearly $69 million for this fiscal year (Choate, 2010). City administrators struggle to find creative solutions to fill financial gaps …

New Front Desk Manual Development Protocols For Millennials Working In The Hotel Industry, Christopher Chennault

UNLV Theses, Dissertations, Professional Papers, and Capstones

Over the past year, the hotel manager of the Westin Versa, Napa, a 179 room franchised hotel located in the city of Napa, California has struggled with conveying to his younger agents (aged 18 to 24) the concept of empowerment. They have had a difficult time with what he defines as "basic common sense" when providing company brand standards to guest recovery situations that go beyond the usual five minutes of a guest interaction. In these scenarios, the young agent is forced to balance the operational needs of the hotel with the wants of the guest and find a middle …

Perception Of Ecological Risk To Water Environments And How It Affects Water Consumption And Water Resource Management In Southern Nevada, Tanju Kiriscioglu

UNLV Theses, Dissertations, Professional Papers, and Capstones

Climate is harsh in southern Nevada where there is (and has been) a drought alert in effect for over a decade now (Kerr, 2007; Southern Nevada Water Authority, 2009). Las Vegas Valley is a major center of population in the region (1.9 million people), receiving only 4.5 inches of average annual precipitation yet in need of securing more water resources in the near future (SNWA, 2009). Water resource management in southern Nevada is a challenge, especially when 90% of the area’s water needs are met by a single source, the Colorado River, the flow rates of which have been in …

Is Virtualization An Appropriate Method Of Disaster Recovery For The Hospitality Industry?, Manognya Murukutla

UNLV Theses, Dissertations, Professional Papers, and Capstones

Organizations across all business sectors are making increasing use of IT today. While other industries have understood the consequences of this dependence in the event of IT disasters and placed a large emphasis on disaster recovery plans and technology, the hospitality industry is lagging behind. One of the reasons why the hospitality industry does not place as much of an importance to disaster recovery is the cost. However, IT disaster is a very damaging occurrence, and measures should be taken to mitigate the event. Loss of a property's information technology (IT) functions can cause chaos in a hotel’s operations leading …

Is Premium Pricing Strategy A Viable Option To Pursue Higher Revenue Performance? A Case Study Of Relative Pricing Strategy In The Singapore Lodging Market, Xiaorong Chen

UNLV Theses, Dissertations, Professional Papers, and Capstones

This is an exploratory research paper on how relative pricing affects an individual hotel’s revenue performance in the Singapore lodging market. First, it measures the REVPAR effects for both a discounting and premium pricing strategy at a local hotel against its competitive set. The findings conclude that a premium pricing strategy is a better way to improve REVPAR performance due to the inelastic nature of the demand curve for hotel rooms in the Singapore market. The findings also show that there is a price limit to a premium pricing strategy, beyond which the growth of REVPAR stagnates because customers were …

The Impact Of Rebranding On Guest Satisfaction And Financial Performance: A Case Study Of Holiday Inn Singapore Orchard City Centre, Pingshan Huang

UNLV Theses, Dissertations, Professional Papers, and Capstones

Velocity Distribution Of Dark Matter Halos: A Critical Test For The Λ Cold Dark Matter Model, Robert Jo Thompson

UNLV Theses, Dissertations, Professional Papers, and Capstones

The existence of a bullet cluster (such as 1E0657-56) poses a challenge to the concordance cold dark matter model. Here we investigate the velocity distribution of dark matter halo pairs in large N-body simulations with differing box sizes and resolutions. We examine various basic statistics such as halo masses, relative halo velocities, collisional angles, and separation distances in our simulations. We then compare the results to the observational properties of 1E0657-56. Our results suggest that it is very difficult to produce such a halo pair with such a high relative velocity at a redshift of z=0. The relative velocities increase …

Latino Locales: Does Context Matter?, Matthew C. Dempsey

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis examines the influence that contextual factors have on the political behavior of Latinos in the United States. I argue that, due to the unique immigration and socialization experiences of Latinos, context will play a role in the political behavior of Latinos. The hypotheses are tested against data collected from a national survey of Latinos conducted in 2006 and the National Election Studies from 2000, 2002, 2004, and 2008. The results of the analysis indicate that context does influence the partisanship of Latinos; however, the effect of descriptive representation for Latinos at the Congressional level does not mirror the …

From Main-Travelled Roads To Route 66: Transitions In Prairie Naturalism, Michelle Nicole Munkres

UNLV Theses, Dissertations, Professional Papers, and Capstones

To best represent a people of a specific spatial and historical context, literary texts must necessarily demonstrate a vested interest and familiarity of a region and its inhabitants’ common experiences. In examining one particular aspect of regional naturalism in American literature, this study explores the basic tenets of Prairie Naturalism as defined by three major authors: Hamlin Garland, Willa Cather, and John Steinbeck. The short stories in Hamlin Garland’s Main-Travelled Roads (1891) establish the foundation of Prairie Naturalism with meticulous attention to daily lives on the plains and with political strategies to improve the lives of the oppressed. Willa Cather’s …

Earthy Bride, Melissa S. Foerster

UNLV Theses, Dissertations, Professional Papers, and Capstones

There are nearly 2.5 million couples getting married in the United States each year (Harrison, 2008, pg. xi). That breaks down to more than 6,300 weddings in a single day. The average wedding in the United States “produces 63 tones of CO2 and 400-600 pounds of trash” and therefore, newlyweds are creating over 3,500,000 pounds of trash in a single at their weddings (Harrison, 2009, ¶ 2)! The green movement is on the rise and wedding industry needs to implement it to meet new demands. In order to do people need to be informed of the importance, benefits and savings …

A Change Management Effort In One Large Public Organization: An Exploration Of The Perception Of Needed Skills For Managing Change, Brian Paul Knudsen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Public managers are a key component of a bureaucracy. The reliance on a public manager by an elected official is high as is the expectations that these managers have the necessary skills to manage a public organization. The goal of this study was to explore what elected officials perceive are skills needed by managers to lessen the impact on the human resource, financial, and political challenges when faced with significant change efforts in order to meet their expectations and that of the citizens to whom the organization is responsible.

Findings indicate that managing upward and managing the political impacts are …

This study investigates the phenomena of second language (L2, hereafter) inner voice for three Japanese-American English bilinguals who had long-term exposure to the L2 in naturalistic contexts, that is, by living and/or working or studying in the U.S. American English learners of L2 Japanese were included in the study as well, although only one of them had naturalistic exposure, the other having traveled to Japan in addition to being married to a Japanese national. Data for the study reveals how and when L2 inner voice is utilized, how it appears to develop, how it leads to shifts in identity toward …

A Longitudinal Study Of Neurocognitive Deficits And Functional Outcome In Bipolar Disorder, Brian D. Leany

UNLV Theses, Dissertations, Professional Papers, and Capstones

Bipolar disorder is an affective disorder that, in addition to being characterized by depressive and expansive mood symptoms, often presents with neuropsychological deficits. Bipolar disorder not only impairs an individual’s cognitive abilities, but these cognitive impairments may also impact day-to-day activities causing functional impairment. In other psychiatric disorders such as schizophrenia, it has been shown that the neuropsychological deficits are predictive of poor, long term treatment outcome and functioning. However, while bipolar disorder affects nearly 1 - 2% of the U.S. population (Keck, McElroy, & Arnold, 2001), little is known about the extent that neurocognitive deficits may play in the …

The Boys' Club: An Exploration Into The Social World Of A Las Vegas Casino Sports Book, Frederick W. Krauss

UNLV Theses, Dissertations, Professional Papers, and Capstones

This ethnography of the La Mesa Casino Sports Book explores the characteristics that frame the social world its regular patrons create. Specifically, I explain the characteristics of La Mesa’s sports bettors, the types of people who bet on sports, the mechanisms used to sustain participation in the scene, and how the sports bettors view themselves, their social world, and those outside of it. I argue that regular sports book patrons do not use the environment simply for sports betting. Rather, their complex interactional dynamics create a robust social world they come back to again and again to create a meaningful …

Opportunities For Intervention: Characteristics Of Alcohol Related Visits To United States Emergency Departments, 2003 - 2007, Jonathon Lavalley

UNLV Theses, Dissertations, Professional Papers, and Capstones

The cycle of alcohol intoxicated patients passing through United States (US) emergency departments (ED) and repeated inpatient detoxification for alcohol inebriates is costly, as these patients are continually exposed to injury and other health and legal consequences of their continued at risk alcohol use. The high proportion of ED resources used by these alcohol intoxicated patients has contributed to increased patient wait times, increased ambulance diversions, forced closures of US EDs, increased numbers of patients leaving without being seen, and an overall reduction in the quality of medical services provided in the ED. In order to contribute to efforts towards …

Adaptive Management Of Complex Environmental Problems – Comparison Of National Nuclear Waste Management Policies, Carmel Letourneau

UNLV Theses, Dissertations, Professional Papers, and Capstones

Many of today's challenging environmental problems, to the point of manifesting themselves on a scale that has global, political consequences, likely result from long-term evolutionary developmental processes. The degree to which humans can manage the evolution of these problems remains an open question. Faced with such challenges, since the mid 1980s, an increasing number of scholars have developed other forms of management, in particular, adaptive management. Scholars suggest that improving the performance of adaptive management requires that environmental problems be understood as 'complex', open, evolving systems of interacting social and environmental subsystems. To date, narrative has been the primary approach …

The Effects Of Cellular Theta Breathing Meditation On Cell Mediated Immune Response: A Controlled, Randomized Investigation Of Altered Consciousness And Health, Marjorie D. Hardgrave

UNLV Theses, Dissertations, Professional Papers, and Capstones

Medical anthropology is well positioned to make contributions to consciousness research based on biocultural approaches that integrate methodologies from the biological, behavioral and social sciences to explore aspects of human health. The ubiquity and perseverance of health related activities involving altered states of consciousness (ASC) across cultures past and present suggest that these potentials are deeply rooted in human sociocultural evolution. Analyzing the relationship between immune function and meditative ASC represents an effort to empirically investigate the adaptive value of these human potentials.

A controlled, randomized investigation of two meditation practices was conducted at the University of Nevada, Las Vegas …

Exploring Preservice Teachers' Views Of Intelligence, Anne Marie Poliquin

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study explored preservice teachers' views of intelligence. Specifically, I was interested in whether preservice teachers believed that intelligence was changeable (incremental) or fixed (entity). Dweck and colleagues found that people view traits like intelligence as either fixed or incremental (Dweck & Leggett, 1988; Dweck, Chiu, & Hong, 1995; Plaks, Grant & Dweck, 2005). Teachers bring both their beliefs and knowledge into the classroom. Views about intelligence affect beliefs about student ability. Teachers' expectations, instructional decisions, teaching strategies, and educational assessment are affected by these beliefs. In order for change to occur, learners must engage deeply (Dole & Sinatra, 1998, …

Monarchs In Love And Other Stories, Matthew Swetnam

UNLV Theses, Dissertations, Professional Papers, and Capstones

Monarchs in Love and Other Stories is a collection of nine short stories. These stories are structurally and tonally heterogeneous, and it is this heterogeneity of form that emerges as the collection's central concern. Present are stories which borrow other forms' organizational conceits (the almanac entries of "Excerpts from the Dwarf-Monger's Handbook"), stories which arrange themselves around arbitrary organizational conceits (the order of the letters of the alphabet in "26 Characters"), and stories which employ radically traditional formal models ("Blind Boy and Mammoth.") Present are stories narrated in the first-person point-of-view ("For a Walk," "Harem Girls"), stories narrated in the …

Civil-Military Relations: A Case Study Of Pakistan, Najiyah Khan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Pakistan is a young and violent nation. It has been under military rule for more than half of its existence and the presence of Islamists in the country has been increasing in recent years. These two actors have played a crucial role in creating the Pakistan of today: a violent, unstable system with revolving governments. What role have civilian governments played while interacting with the Islamists and the ever present military? What has led to the Pakistan we see today? Is there any hope that Pakistan can remove the violent actors within its borders and create real change to become …

Toward The Development Of A Model To Estimate The Readability Of Credentialing-Examination Materials, Barbara Anne Badgett

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to develop a set of procedures to establish readability, including an equation, that accommodates the multiple-choice item format and occupational-specific language related to credentialing examinations. The procedures and equation should be appropriate for learning materials, examination materials, and occupational materials. To this end, variance in readability estimates accounted for by combinations of semantic and syntactic variables were explored, a method was devised to accommodate occupational-specific vocabulary, and new-model readability formulas were created and calibrated. Existing readability formulas were then recalibrated with the same materials used to calibrate the new-model formulas. The new-model and recalibrated …
