UNLV Theses, Dissertations, Professional Papers, and Capstones

Background Beds and breakfast are the small business component of the hotel industry. Like all types of small businesses, many fail due to poor planning or misguided management. As more new entrepreneurs enter the market due to the decline of the economy and the unreliability of corporate America, it is important to identify the proper components of a business plan for beds and breakfast and to outline a successful operations model. A study of business plan and bed and breakfast operation models is included here. Results Existing literature suggests several components of a successful business plan. These include a detailed …

Adjustments In Inter-Cultural Communication Of Expatriate And Host National In Local Operation, Hanna Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

Due to the global expansion of international hotel chains into culturally isolated countries, such as China, many hotels are in need of qualified staffs in local operation where a strong culture exists. When expatriate managers are sent abroad for overseas assignments, they are often confronted with the conflicts that are caused by inter-cultural differences between expatriates and host nationals. This paper examines several aspects of cultural and interpersonal issues involved in the conflicts, and seeks to determine any necessary adjustment from the information gathered by telephone interviews with the current expatriate managers in Beijing, China. Furthermore, the study discusses essential …

From the whole adult body to tissue function to molecular networks, if a biological question arises it most likely can be …

The Determinants Of U.S. Foreign Aid Allocation To Sub-Saharan Africa In The Pre-Terror And Post-Terror Security Environments, Brendan Mark Morris

UNLV Theses, Dissertations, Professional Papers, and Capstones

Foreign aid has become a growing importance of U.S. foreign policy in the last few years. As the U.S. is committing more aid towards the developing world, questions over the purpose of this expansion of aid have emerged. While the traditional perspectives on the purpose of foreign aid of either serving the strategic interests of the donor or the development interest of the recipients are given as potential reasoning behind this allocation of aid, the impact of the U.S.’s involvement in the War on Terror may have more of a significant impact on the U.S.’s current foreign aid allocation. Foreign …

Multiform Segregation In The Context Of The Urban Crises In Las Vegas And Los Angeles, 1930 - 1980, Colin M. Fitzgerald

UNLV Theses, Dissertations, Professional Papers, and Capstones

Multiform segregation in the context of the urban crises was a complex socio-historical phenomenon. The primary focus of this study addresses racial segregation in at least three basic societal areas: housing, employment, and education. Through the spatial separation of multiple ethnoracial groups such as African Americans and Mexican Americans, multiform segregation precipitated the urban crises. In the 50-year period this study covers, Las Vegas and Los Angeles sustained a two-tiered class system according to the prevailing racial attitudes of each city's business elite. As a resort city, Las Vegas could not endure ethnoracial tensions while Los Angeles' industrial base provided …

The ANOVA analysis of the STEBI-B revealed a statistically significant increase in level of …

Vibrational Spectroscopic Study Of The 1,3,5,7-Cyclooctatetraene At High Static Pressures, Edward Romano

UNLV Theses, Dissertations, Professional Papers, and Capstones

1,3,5,7-cyclooctatetraene (COT) is a single-ringed hydrocarbon that has not been studied extensively under high static pressures. It was the intent of this study to reveal its high-pressure behavior through its vibrational spectra. To this end, its infrared spectra as a function of pressure were collected at the National Synchrotron Light Source (NSLS) U2A beamline, as well as its Raman spectra over pressure using a micro-Raman spectrometer.

The spectra show the typical stiffening of force constants with increasing pressure for most peaks, particularly those which would theoretically exhibit a mode-softening behavior under hypotheses of molecular planarization and aromatization. Additionally, the data …

Initial Development Of A Healthy Living Curriculum Within Family Behavior Therapy For Substance Abuse, Holly B. Lapota

UNLV Theses, Dissertations, Professional Papers, and Capstones

A mother referred for child maltreatment and substance abuse treatment after her son tested positive for methamphetamines at birth participated in an in-home Family Behavior Therapy-Healthy Lifestyle intervention to eliminate substance use, improve parenting behaviors, lose weight, and develop better exercise habits. Twenty sessions were completed in 6 months that targeted familial communication, self-control, goal setting with contingency management, job getting skills, and stimulus control techniques. Upon termination from treatment, the participant’s self-report and urine testing was consistent with substance cessation, and she evidenced substantial improvements in her level of stress, family communication and relationships, and child maltreatment potential. She …

Cascading Simulation: A Critical Perspective On Barack Obama‘S Foreign Policy During The 2008 Presidential Election, Ian P. Beier

UNLV Theses, Dissertations, Professional Papers, and Capstones

Entering the 2008 presidential election, Barack Obama had little to no foreign policy experience. On face, this would seem to make Obama an unlikely choice for President. Yet, he was able to defeat Hilary Clinton and John McCain, the two candidates with significant foreign policy experience. My thesis examines Barack Obama's speech "A World That Stands as One" as a case study for understanding how simulation operates in the context of presidential campaigns. Using Robert Entman's theory of "cascading activation," I develop a theory of "cascading simulation," arguing that image construction descends downward from the president through the media. In …

Transcriptional Regulation Of The Shigella Flexneri Icsp Promoter: Silencing And Anti-Silencing By H-Ns And Virb, Dustin Harrison

UNLV Theses, Dissertations, Professional Papers, and Capstones

Shigella species are gram-negative intracellular pathogens that cause bacillary dysentery in humans. Many genes required for virulence of Shigella are carried on a large 230 kb plasmid and many of these are under the transcriptional control of the histone-like nucleoid structuring protein (H-NS) and by the major virulence regulator VirB. At the non-permissive temperature of 30⁰C, H-NS represses transcription, while at 37⁰C VirB alleviates this repression. This mechanism of gene regulation has been coined "silencing/anti-silencing" and is commonly found in many important bacterial pathogens including Salmonella spp. and Yersinia spp. The icsP gene, encoded by the Shigella virulence plasmid, is …

Stereotype Threat’S Effect On Women’S Achievement In Chemistry: The Interaction Of Achievement Goal Orientation For Women In Science Majors, Janice M. Conway-Klaassen

UNLV Theses, Dissertations, Professional Papers, and Capstones

"Stereotype threat is being at risk of confirming, as a self-characteristic, a negative stereotype about one's group" (C. M. Steele & Aronson, 1995, p. 797). A stereotype threat effect then is described as the detrimental impact on a person's performance or achievement measurements when they are placed in a stereotype threat environment.

For women, the negative stereotype that exists in our culture states that women are typically not as capable as men in mathematics or science subjects. This study specifically explored the potential impact of stereotype threat on women who have chosen a science-based college major. They were tested in …

An Analysis Of The Equity Of Utah’S Public School Funding System, Garrick Peterson

UNLV Theses, Dissertations, Professional Papers, and Capstones

There has not been an equity study of the public school funding allocation system, in the state of Utah, since 1990. The purpose of the study was to conduct an analysis of the equity of the Utah state funding allocation system for K-12 education including a trend analysis for the decade 2000-2009. The conceptual framework for the analysis applies four broad concepts of equity framed by Kern Alexander; (1) communitative equity, (2) distributive equity, (3) restitutive equity, and (4) positivism. The analysis of the Utah State funding system used Berne and Stiefel's methodology and included commonly used statistical measures of …

Visual Occam: High Level Visualization And Design Of Process Networks, Mikolaj M. Slomka

UNLV Theses, Dissertations, Professional Papers, and Capstones

With networks, multiprocessors, and multi-threaded systems becoming more common in our world it is increasingly evident that concurrent programming is not something to be ignored or marginalized even though many takes on concurrency (mainly by means of monitors or shared resources) have proven to be difficult to deal with on large scales. Thankfully, a good deal of work has already been done to combat this, through CSP, occam, and other such derivatives, to produce a scalable process oriented paradigm. Still, it is cumbersome to attempt to deal with the intricacies of such communicating networks down to every minutia; if, instead, …

High School Student Interests In Architecture, Construction, And Engineering Education, Krishna P. Kisi

UNLV Theses, Dissertations, Professional Papers, and Capstones

It is a common and widely held belief that the greatest influencing factor for high school students to enter an architecture-, construction-, or engineering-education program is because either their parents, relatives or friends work or have worked in the industry. However, there is little research that supports this belief. The focus of this research was to analyze characteristics and academic interests of Clark County School District (CCSD) Career and Technical Academies (CATA) students enrolled in architecture, construction and engineering (ACE) curricula.

This research analyzed data collected from a survey conducted by CCSD of their students enrolled in ACE courses. Comprehensive …

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this study, 166 undergraduates from an Educational Psychology subject pool were randomly assigned to different task value instructional inductions (utility, attainment, and control) to determine whether inducing students with differing task values would be effective and result in different degrees of engagement for a learning task, as well as result in different degrees of conceptual change on the topic of the causes of the common cold. It was hypothesized participants would adopt characteristics that were consistent with the task value with which they were induced, that the participants in the utility, attainment, and control conditions would differ in their …

Fabrication, Characterization And Simulation Of Non-Lithographic Nanostructures And Their Potential Applications, Neelanjan Bhattacharya

UNLV Theses, Dissertations, Professional Papers, and Capstones

The dissertation describes the formation of porous silicon through the pores of porous alumina on a silicon substrate. Porous silicon, by itself, is inherently a non-uniform material that has non-uniform optical and electronic properties. In addition, it is also mechanically fragile material requiring careful material handling. The porous silicon fabricated through the nanosized pores of porous alumina are expected to mitigate these problems, thereby enhancing commercial viability of the device. The porous silicon as well the porous alumina have been synthesized through anodisation for various parameters and also various types of anodizing electrolytes. The porous silicon, so obtained have been …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Las Vegas Valley, located in the arid Southern Nevada region, with a growing population, limited water resources, and a prolonged drought, faces a challenge in meeting its future water needs. Southern Nevada Water Authority (SNWA), the main water management agency in the Valley, is focusing on water conservation to reduce water demand. Current water use is 945 lpcd (250 gpcd) which SNWA aims to reduce to 752 lpcd (199 gpcd) by 2035. Presently the indoor outdoor water use proportion is about 40:60 in the Valley. An important component of the Valley's supply are the return flow credits which SNWA …

Conservation Based Uncertainty Propagation In Dynamic Systems, Lillian J. Ratliff

UNLV Theses, Dissertations, Professional Papers, and Capstones

Uncertainty is present in our everyday decision making process as well as our understanding of the structure of the universe. As a result an intense and mathematically rigorous study of how uncertainty propagates in the dynamic systems present in our lives is warranted and arguably necessary. In this thesis we examine existing methods for uncertainty propagation in dynamic systems and present the results of a literature survey that justifies the development of a conservation based method of uncertainty propagation. Conservation methods are physics based and physics drives our understanding of the physical world. Thus, it makes perfect sense to formulate …

This study investigates supervisor gender and various dimensions of employee job satisfaction within the casino-entertainment sector of the hospitality industry. Specifically, these dimensions were analyzed from the perspective of three variables related to individual employees: (1) satisfaction with company; (2) satisfaction with department; and, finally, (3) satisfaction with the supervisor. The data for this study was obtained from an employee survey administered to employees in three separate Nevada casino-entertainment properties and their corresponding corporate office. The results of this study fill existing gaps in the academic literature related to job satisfaction and the role of supervisor gender. There are implications …

The Experience Of Feelings In Depression, Noelle L. Lefforge

UNLV Theses, Dissertations, Professional Papers, and Capstones

Emotions, such as sadness, guilt, and irritability, are at the core of depressive symptoms and suggest a need for an in-depth understanding of feelings, the experiential component of emotion, during depression. Therefore, the purpose of this study was to describe the experience of emotion in depressed participants and find out if these experiences are similar to those of nondepressed participants. Descriptive Experience Sampling (DES) was used to sample five depressed and four nondepressed participants for four days and then in a controlled setting while watching positive, negative, and neutral film clips. Due to the limited sample size, this study was …

Detours Admitting Short Paths, Reshma Koganti

UNLV Theses, Dissertations, Professional Papers, and Capstones

Finding shortest paths between two vertices in a weighted graph is a well explored problem and several efficient algorithms for solving it have been reported. We propose a new variation of this problem which we call the Detour Admitting Shortest Path Problem (DASPP).We present an efficient algorithm for solving DASPP. This is the first algorithm that constructs a shortest path such that each edge of the shortest path admits a detour with no more than k−hops. This algorithm has important applications in transportation networks. We also present implementation issues for the detour admitting shortest path algorithm.

The Live Experience Of Non-Degree Learners From A Time Modified Traditional Baccalaureate In Nursing Program, Stephanie S. Deboor

UNLV Theses, Dissertations, Professional Papers, and Capstones

By the year 2016, it is projected that a million new and replacement nurses will be needed throughout the United States. The traditional 4-year baccalaureate program alone cannot adequately sustain this demand. The immediacy of the current nursing shortage demands our educational systems respond by building and maintaining a workforce that is sufficient to support the health care needs of our society. In an attempt to meet this challenge, nursing schools around the country began exploring the option of creating accelerated programs for those who already possess a bachelor's degree in another field without compromising the integrity and quality of …

The Advisor-Advisee Relationship: A Qualitative Study Of Advisee Perspectives, Paula M. Emke-Francis

UNLV Theses, Dissertations, Professional Papers, and Capstones

Attempts to understand the nature and course of advising relationships in clinical psychology doctoral training have been limited in number and scope. Furthermore, they have almost universally applied theoretical models derived for the explanation of different types of relationships, with very little empirical inquiry aimed at examining the advising relationship as it actually exists. The present study sought to better understand advisory relationships in clinical psychology doctoral training and propose a theoretical model related to the dimensions of the relationship that emerged.

This was accomplished via semi-structured interviews with 18 clinical psychology Ph.D. candidates from training programs across the United …

The Effects Of Contact Metamorphism On The Host Rocks For Carlin-Type Mineralization At The Getchell Development, Nevada, Usa, Nathan C. Eck

UNLV Theses, Dissertations, Professional Papers, and Capstones

Carlin-type gold deposits (CTGDs) result from low to moderate temperature hydrothermal systems which form replacement bodies in carbonate or calcareous host rocks. The Getchell CTGD is located on the Getchell trend in north central Nevada. The Eocene age mineralization is locally hosted within the metamorphic aureole of the Cretaceous age Osgood stock. Previous studies have noted that the effects of the contact metamorphism can be heterogeneous, with strongly calc-silicate altered carbonates transitioning to relatively pristine limestone over short distances. The main finding of this study was that the variability in calc-silicate alteration is largely dependent on the differing host lithologies …

Mediating And Moderating Variables Between Discretionary Purchases And Happiness, Rebecca L. Thomas

UNLV Theses, Dissertations, Professional Papers, and Capstones

Media and societal images suggest that the accumulation of objects, possessions, and wealth will produce happiness. However, research has found higher rates of materialism are associated with lower levels of happiness. The current studies explored the relationship between different types of purchases and happiness. Specifically, experiential purchases are distinguished from material purchases in terms of goal; experiential purchases have the goal of acquiring a life experience, while material purchases have the goal of acquiring an object. Several studies have found that experiential purchases are associated with more happiness than material purchases. A number of variables that mediate and moderate the …

The Effects Of Cultural Experience And Subdivision On Tapping To Slow Tempi, Sangeeta Ullal

UNLV Theses, Dissertations, Professional Papers, and Capstones

Our ability to accurately synchronize with rhythmic patterns is constrained by two factors: temporal length and interval structure. By using strategies such as subdivision, we can improve synchronization accuracy at slow tempos, but our ability to utilize subdivisions is constrained by the nature of interval ratios contained in culture-specific subdivision types. Western music falls within a restricted temporal range and its metrical subdivisions contain simple ratios, but Indian music violates these constraints. The present study examines the effects of culture-specific experience on these constraints. American and Indian listeners were asked to perform synchronous tapping to a stimulus with a slow …

Presenilin Is Necessary For The Function Of Cbp In The Adult Drosophila Cns, Randy S. Boyles

UNLV Theses, Dissertations, Professional Papers, and Capstones

Dominant mutations in Presenilin (Psn) have been correlated with the formation of Aß- containing plaques in patients with inherited forms of Alzheimer's disease (AD). However, a clear mechanism directly linking amyloid plaques to the pathology of familial or sporadic forms of AD has remained elusive. Thus, recent discoveries of several new substrates for Psn protease activity have sparked alternative hypotheses to explain the preclinical symptoms of AD. CBP (CREB-binding protein) is a haplo- insufficient transcriptional co-activator with histone acetyltransferase (HAT) activity that has been proposed to be a downstream target for Psn signaling. Individuals with reduced CBP levels have cognitive …
