Compliance with the permit requires implementation of the Clark County Multiple Species Habitat Conservation Plan. This plan requires an adaptive management program and a biennial report by an independent science advisor to assess the status of the plan and make recommendations for future funding. This 2010 Adaptive Management Report reviews current data on land use trends, habitat loss, species status and plan implementation, and makes recommendations for the future.

Hotel Guests’ Perceptions Of Sustainable Hotel Practices In A Mexican Destination, Orie Berezan, Michelle Millar, Carola Raab

Caesars Hospitality Research Summit

Hotel selection and attributes that are important to travelers has been extensively researched using a variety of methods (Dolnicar, 2002). Dolnicar & Otter (2003) confirmed, after reviewing 21studies related to hotel attributes, cleanliness as the top priority, followed by hotel location. In total, 173 attributes were identified that were related to image, price/value, the hotel itself, and service (Lockyer, 2005). None of those attributes, however, were related to environmental attributes of a hotel. For more than a decade, the hospitality industry has been under pressure by government legislation and regulations to implement environmental strategies and thereby reduce their carbon footprint …

Caesars Hospitality Research Summit

As customers’ ecological concern is steadily increasing, demand for products and services designed to be less harmful to the environment has augmented. By executing green practices, many business owners believe the image of their companies can be improved. Furthermore, the improved image may eventually motivate the customers to use products or services offered by the green company. The restaurant industry is witnessing the green movement as well. Restaurant owners adopt green practices to their properties with the purpose of creating a distinctive image that can differentiate them from their competitors. Therefore, restaurateurs strive to get this competitive advantage by introducing …

Photovoltaics (Pv) As An Eligible Measure In Residential Pace Programs: Benefits And Challenges, Jason Coughlin

Publications (E)

Property Assessed Clean Energy (PACE) financing is one of several new financial models broadening access to clean energy by addressing the barrier of initial capital cost. The majority of the PACE programs in the market today include PV as an eligible measure. PV appeals to homeowners as a way to reduce utility bills, self-generate sustainable power, increase energy independence and demonstrate a commitment to the environment. If substantial state incentives for PV exist, PV projects can be economic under PACE, especially when partnered with good net metering policies. At the same time, PV is expensive relative to other eligible measures …

Examination Of The Regional Supply And Demand Balance For Renewable Electricity In The United States Through 2015: Projecting From 2009 Through 2015 (Revised), Lori Bird, David Hurlbut, Pearl Donohoo, Karlynn Cory, Claire Kreycik

Publications (E)

This report examines the balance between the demand and supply of new renewable electricity in the United States on a regional basis through 2015. It expands on a 2007 NREL study (Swezey et al. 2007) that assessed the supply and demand balance on a national basis. As with the earlier study, this analysis relies on estimates of renewable energy supplies compared to demand for renewable energy generation needed to meet existing state renewable portfolio standard (RPS) policies in 28 states, as well as demand by consumers who voluntarily purchase renewable energy. However, it does not address demand by utilities that …

The History Of Baccarat, Theodore Whiting

Occasional Papers

The true origins of modern Baccarat are probably lost to history. The first time the game Baccarat (spelled Baccara) was mentioned in print by a contemporary observer was in the early 19th century. The written record that would document the origins and evolution of the game is, unfortunately, incomplete. However, a close examination of the available material reveals some interesting facts surrounding the history of Baccarat, including a much earlier date for its arrival in the United States, that validates its continuing study.

Publications (E)

Voluntary markets for renewable energy in which consumers purchase renewable energy from their electricity providers or from renewable energy certificate (REC) marketers have existed for more than a decade. Going forward, various factors will influence the development of these markets, including potential climate policies, state and federal renewable portfolio standards (RPS), renewable energy prices, the level of consumer interest in purchasing green power, and the interest on the part of utilities in offering new green options and in continuing to promote existing programs.

This report presents estimates of voluntary market demand for renewable energy or green power through 2015. The …

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 …

Antimicrobial Activity Of D-Lenolate®, Andy Phui

UNLV Theses, Dissertations, Professional Papers, and Capstones

Olive trees are one of the most important fruit trees in the Mediterranean. Although not validated by research, olive leaves are traditionally believed to fight off fever and infections. It has been shown that olive leaf extracts possess antimicrobial activity. Olive leaf extracts contain polyphenols. One of the major phenolic compounds is oleuropein. Oleuropein and other polyphenols have been shown to exhibit antimicrobial activity. East Park Research (EPR) developed an extraction process that they claim does not alter the chemical composition of the olive leaves. The extract is known by the commercial name d-lenolate®. Studies have provided evidence that d-lenolate®, …

Partial Phonon Density Of States Of 57-Iron And 161-Dysprosium In Dyfe3 By Nuclear Resonant Inelastic X-Ray Scattering Under High Pressure, Elizabeth Anne Tanis

UNLV Theses, Dissertations, Professional Papers, and Capstones

The dual partial phonon density of states (DOS) from two different Mossbauer isotopes (161Dy and 57Fe) in the same material (DyFe3) was successfully measured using the nuclear resonant inelastic x-ray scattering (NRIXS) technique at high pressure. Nuclear inelastic scattering measurements yield an in-depth understanding of the element-specific dynamic properties. The Debye temperatures , the Lamb-Mossbauer factor, and the vibrational contributions to the Helmholtz free energy, specific heat , entropy and internal energy are calculated directly from the phonon density of states.

Bacillus Cereus And Bacillus Anthracis Germination Kinetics: A Michaelis-Menten Approach, Helen Luu

UNLV Theses, Dissertations, Professional Papers, and Capstones

Bacillus species are rod-shaped, gram-positive bacteria that are capable of producing endospores. In this dormant stage, the endospores can persist in hostile physical and chemical environments. Once conditions become favorable, the spores germinate into actively dividing cells, vegetative cells. Germination is a crucial step for the pathogenicity of the Bacilli in affecting a host organism.

Our study applies mathematical approaches to spore germination to determine whether the binding of one germinant will affect the binding of another germinant. We pursued this approach with two different species, B. cereus and B. anthracis, both pathogenic organisms. B. cereus is a widely known …

Incidental Music: Enhancing The Emotional Experience Of The Audience, Daniel Edward Nelson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Environmental psychologists, like Robert Gifford who study transactions between individuals and their physical settings, maintain that as an individual's environment is changed, the environment also changes his/her behavior and experience. (Gifford, 2002) Like other segments of a theatrical setting, manipulation of the environment can enhance or constrain a broad range of audience actions from traditional theatre audiences to shoppers in a mall or guests at a wedding. Physical elements, as well as other ambient factors such as lighting, color, and quality of materials, set design, music, fragrance, and room temperature are a sample of the dramatic elements used to orchestrate …

Petrogenesis Of The Greenwater Range: Comparison To The Crater Flat Volcanic Field And Implications For Hazard Assessment, Ashley Kaye Tibbetts

UNLV Theses, Dissertations, Professional Papers, and Capstones

Pliocene basalts of the Greenwater Range, California erupted from 24 volcanic vents now represented by volcanic plugs, craters and scoria mounds. Basaltic magmas originated in the asthenospheric mantle, but show evidence of a lithospheric component. Depths and temperatures of melting calculated using a silica activity geobarometer are 54.3–89.6 km and 1367-1435oC, placing melting in the asthenosphere. The preferred petrogenetic model involves melting of lithospheric mantle thermally and mechanically, but not chemically, converted to asthenospheric mantle. Melting depths correspond to low velocity zones in the mantle as revealed in seismic profiles. Chemical and lithologic similarities between basalt in the Greenwater Range …

Statistical Modeling And Analysis Of Injury Severity Sustained By Occupants Of Passenger Vehicles Involved In Crashes With Large Trucks, Ahmad Koupaenejad

UNLV Theses, Dissertations, Professional Papers, and Capstones

Crashes are the result of complex interactions between several factors representing driver, roadway, vehicle, and environmental characteristics. Understanding to what degree each factor contributes to the severity of a crash is not a simple task. The outcomes of crashes in the US have been an average of 42,000 deaths and 3 million injuries per year. To better understand the role of significant contributors to crashes, three sets of models using multinomial logit and one using ordered probit were calibrated. To calibrate these models, forty two independent predictor variables including driver/occupants characteristics, crash environment at the crash location, crash characteristics, and …

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 ball was then removed from the cable and returned to the pedestal so as to end each trial at rest. This was repeated 10 times with 5 …

Preparation And Characterization Of Extraction Chromatography Resins Using N-Donor Extractants For Trivalent Actinide And Lanthanide Separations, Christopher L. Klug

UNLV Theses, Dissertations, Professional Papers, and Capstones

Actinide and lanthanide elements exist in the geosphere and biosphere due to both natural abundances and anthropogenic activities. The investigation of the presence and transport of actinides through the environment is of great scientific interest. In order to prepare environmental samples for precise measurements, the individual actinides must be separated from the chemically similar lanthanides, and from neighboring actinides. Existing extraction chromatography resins are either poorly suited for this separation, have bleeding problems, are not reusable, or fail the CHON principle. In an effort to resolve these issues, malonamides and N-donor extractants from the BTP and BTBP classes of solvent …

Education can be extremely important to an individual’s success.

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, …

An Investigation Of Exemplary Teaching Practices Of Teachers Of Native American Students, William M. Young

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation traces the historical roots of indigenous education from the violation of treaty rights of the late 1800's to the staggering rates of non-persistency facing Native American students today. While many factors are outside of the classroom teacher's scope of influence, teacher candidates should be trained in culturally responsive methods to address factors that are within their control and which can be addressed in the classroom.

The study was conducted using a mixed-methods design employing Creswell's (2008a) sequential transformative strategy. STS is a multi-phase study with an implicit theoretical lens. In this study the researcher is situated at an …

A Comparative Study On Text Categorization, Aditya Chainulu Karamcheti

UNLV Theses, Dissertations, Professional Papers, and Capstones

Automated text categorization is a supervised learning task, defined as assigning category labels to new documents based on likelihood suggested by a training set of labeled documents. Two examples of methodology for text categorizations are Naive Bayes and K-Nearest Neighbor.

In this thesis, we implement two categorization engines based on Naive Bayes and K-Nearest Neighbor methodology. We then compare the effectiveness of these two engines by calculating standard precision and recall for a collection of documents. We will further report on time efficiency of these two engines.

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 …
