Patient Preference For The Management Of Mildly Abnormal Papanicolau Smears, Marta Meana, Donna E. Stewart, Gordon M. Lickrish, Joan Murphy, Barry Rosen

Psychology Faculty Research

The article provides information on a study that investigated management preference and desire for decision-making involvement in women who have received a first mildly abnormal Papanicolaou smear. The majority of women in this highly educated sample preferred active management of their mildly abnormal Pap smears, although a substantial minority either opted for the surveillance strategy or reported no strong preference. Furthermore, management preference in this sample was not related to knowledge but rather to level of state anxiety. This indicates that these decisions may be guided more by emotions than by facts. Research has shown repeatedly that abnormal Pap smears …

Evidence Supporting The Recent Origin And Species Status Of The Timberline Sparrow, John Klicka, Robert M. Zink, Jon C. Barlow, W. Bruce Mcgillivray, Terry J. Doyle

Ornithology Program (HRC)

The Timberline Sparrow (Spizella taverneri), although originally described as a species, is currently classified as a subspecies of the more widespread Brewer's Sparrow (S. breweri). We investigated the taxonomic status and recent evolutionary history of these species by comparison of both morphological and molecular characters. Morphometric comparisons using 6 external and 18 skeletal measurements show that S. taverneri specimens from two widely separated populations (Yukon and southwestern Alberta, Canada) are indistinguishable with respect to size yet are significantly larger (by 3%) than representatives of several breweri populations. Analysis of 1,413 base pairs of mitochondrial DNA (mtDNA) for 10 breweri and …

Life Beyond Nuclear Testing The Nevada Test Site, Fina Martinez-Myers

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Nevada Test Site (NTS) has served a crucial role in protecting the nation's security over the last 50 years. Changing national budgets and fiscal priorities have signaled dramatic adjustments for the NTS. Following the 1992 nuclear testing moratorium, the U.S. government has begun to make parts of the NTS available for private-sector use in an effort to generate money, utilize the Test Site's unique resources and capabilities, and provide economic development to southern Nevada. The initiative to attract private industry to the NTS is similar to activities taking place at other nuclear facilities across the nation. With a change …

Low-Temperature Molecular Beam Epitaxy Of Gaas: A Theoretical Investigation Of Antisite Incorporation And Reflection High-Energy Diffraction Oscillations, K. Natarajan, Rama Venkat, Donald L. Dorsey

Electrical & Computer Engineering Faculty Research

Surface dynamics dominate the incorporation of charged, As+Ga, and neutral, As0Ga, antisite arsenic, and the temporal variation of reflection high-energy electron diffraction(RHEED) intensity in the low-temperature molecular beam epitaxy of (100) gallium arsenide(GaAs). A rate equation model is proposed which includes the presence and dynamics of a physisorbed arsenic (PA) layer riding the growth surface. The PA layer dictates the incorporation and concentration of As+Ga and As0Ga. Additionally, it influences the RHEED oscillations (ROs) behavior and the RO’s dependence on its coverage through its contribution to the reflected intensity. The model results for the dependence of As+Ga and As0Ga concentrations …

Geochemistry And Petrogenesis Of The Bonanza King Mafic Intrusive Complex, Trinity Terrane Ophiolite, California, Keith R. Willse

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Bonanza King mafic intrusive complex (MIC) (>25 km^2₎ of the Trinity terrane ophiolite, northern California, consists of cogenetic plutonic and dike lithologies. Steep intrusive contacts exist between cumulate pyroxenite, isotropic gabbro, and peridotite country rock. Near vertical east-west trending, bimodal dikes intruded gabbro and are centered within the complex. Geochemical modeling indicates taht accumulation/fractionation of a gabbroic parental magma produced lithologic trends of cumulate pyroxenite and fractionated gabbro and dike lithologies. Similarities between all lithologies suggest cogenetic formation of all the elements of the Bonanza King MIC during the Late Silurian (431 +/- 3).

Parental magma …

The Geochronology And Geochemistry Of The Bearhead Rhyolite, Jemez Volcanic Field, New Mexico, Leigh Justet

UNLV Theses, Dissertations, Professional Papers, and Capstones

Around 82% of mapped Bearhead Rhyolite (Main Cluster) and Peralta Tuff appears to have been derived from a relatively long-lived (~680 ka), large, shallow (Earth's surface) magma chamber that did not produce a caldera-forming eruption. Although volatile contents were great enough (~ wt.% H₂O), no large-scale explosive eruptions occurred because magma may have been tectonically vented. The lack of systematic chemical variation within the Main Cluster with time during this ~680 ka interval may imply that erupted magmas were physically separated from each other by fault-formed cupolas in the roof of the magma chamber. These results are significant …

The Origin Of Brucite In Hydrothermally Altered Limestone Near Devil Peak, Nevada, Rhonda L. Knupp

UNLV Theses, Dissertations, Professional Papers, and Capstones

Open-space brucite was identified in veins crosscutting hydrothermally altered limestone near the Devil Peak rhyolite plug in southern Nevada. The brucite occurs with serpentine, calcite, chalcedony, hydromagnesite, dolomite, and clinochlore.

Brucite usually forms as a replacement mineral, but textural evidence indicates that the brucite at Devil Peak precipitated in open space. The presence of chalcedony in veins indicates the temperature of the hydrothermal fluid was <180^oC during and after mineral deposition. Thermodynamic modeling shows this temperature is too low for replacement brucite to form, thus the low temperature of alteration may be a factor in this unusual occurrence of …

Data were collected from a sample of 57 older adults (aged 55 and over) from three Las Vegas Senior Centers using an instrument developed by the investigator. Findings revealed that relationships, recreation, and relatedness contributed to reasons for participation. Rewards did not seem to affect participation. In terms of demographics, more participants tended to be older, female, and educated. Enabling variables revealed participants …

Bigger Than A Ballot Box, Joanne Goodwin

History Faculty Research

The relationship between the histories of woman suffrage and U.S. politics suffered from a reluctance on the part of both fields to include the other until recently. Political historians refrained from in-depth discussions of the eighty-year movement to gain the vote for women until the new political history expanded the definition of political actors and activities. Women's historians (with a few notable exceptions) discussed the suffrage movement as a type of voluntarist reform activity, rather than contextualizing it within political institutions and systems. Ellen Carol DuBois's study of suffrage through the passage of the Fourteenth and Fifteenth Amendments departed significantly …

Golf Courses In Southern Nevada Will Significantly Impact The Water Management Efforts By Using Recycled Water Rather Than Potable Water To Irrigate Their Turf, Sean D. Ainsworth

UNLV Theses, Dissertations, Professional Papers, and Capstones

As the number of people continually move to the Las Vegas Valley and take up residence, the possibility of "running out of water" can become a reality. Having large water users (i.e. golf courses) irrigate their turf with recycled water, they will significantly impact the water management efforts in the Las Vegas Valley. When each course is irrigating their turf with recycled water, this will help ease the drinking water demand in the valley, especially during the peak demand season (summer).

The Las Vegas Monorail, An Innovative Solution For Public Transportation Problems Within The Resort Corridor, Cam C. Walker

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Las Vegas Monorail project is the first and quite possibly the only private sector endeavor to construct mass transit grade transportation at no cost to the taxpayer, and with no public sector investment, subsidy, or guarantee. The Las Vegas Monorail project follows a structure similar to the innovative toll road projects of the last decade, illustrating how other transportation problems can be solved by similar procedures. This study provides an opportunity to get an inside look at the process of designing, building, operating, maintaining, and financing a major transportation project in Las Vegas and the unique cooperation between public …

Do User Fees Violate Nonmember Rights?, Jerry Hartman

UNLV Theses, Dissertations, Professional Papers, and Capstones

User fees are moneys charged non-union members by their representative union for the purpose of processing grievances. The non-member has to request the union to represent them in order for the union to do so. They may also hirer private representation at their own cost. User fees violate the intent of right-to-work laws in Nevada. The Nevada Local Government Employee-Management Board was wrong when they allowed Union/Local 1107 to charge such fees. The "Executive Board Policy" posted by Local 1107 on union bulletin boards announcing the fees for representation was coercive and discriminatory. According to survey, 40% of the respondents …

A Comparative Assessment Of The Status, Structure And Process Utilized By Nevada's Family Support And Preservation Consortia To Achieve Collaboration, Marlys A. Morton

UNLV Theses, Dissertations, Professional Papers, and Capstones

This paper presents a framework for understanding inter-organizational collaboration and describes and analyzes how collaboration was used as a method to build new service networks, the characteristics of the consortia, and the status of the collaborative processes.

Although the literature on inter-organizational collaboration in the human services is increasing, little is known about how regional consortia view the process of working together towards a common purpose. The results reported in this paper are intended to help fill that gap.

The findings reported in this study are based on a survey process using a standardized questionnaire to study the collaborative status. …

Rio Natural Gas, The Alternative Fuel Of The Future, Peter Garner

UNLV Theses, Dissertations, Professional Papers, and Capstones

Automobile exhaust is a major contributor of harmful air pollutants. Exhaust emissions include water (H2O), carbon dioxide (CO2), carbon monoxide (CO), nitrous oxides (NOX), sulfur oxides (SOX), hydrocarbons (HC), and particulate matter (PM), and of these the four major air pollutants are CO, HC, NOX, and PM. Particulate matter is predominantly emitted from diesel fuel burning vehicles. In order to aid in reduction of air pollution, and reduce dependence on foreign oil imports, federal legislation has been enacted. The two prominent acts are the National Energy Security Act in 1992, which mandates use of alternative fuels, and the Clean Air …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study is to compare and analyze student uniform policies in public school districts within the United States and to ascertain whether or not they are effective. Available information from America's 70 largest school districts is collected and compared to determine if the policies are feasible. Findings indicate there is a broad spectrum of ways in which the districts address student attire and imply that most of the districts are not adapting uniform policies, but are leaving the decision up to individual schools and to the parents. Districts that are adapting policies boast favorable results. Although statistical …

Sliding Mode Measurement Feedback Control For Antilock Braking Systems, Cem Unsal, Pushkin Kachroo

Electrical & Computer Engineering Faculty Research

We describe a nonlinear observer-based design for control of vehicle traction that is important in providing safety and obtaining desired longitudinal vehicle motion. First, a robust sliding mode controller is designed to maintain the wheel slip at any given value. Simulations show that longitudinal traction controller is capable of controlling the vehicle with parameter deviations and disturbances. The direct state feedback is then replaced with nonlinear observers to estimate the vehicle velocity from the output of the system (i.e., wheel velocity). The nonlinear model of the system is shown locally observable. The effects and drawbacks of the extended Kalman filters …

Nevada Procurment Laws For Computer Related Items For Public Agencies, Rick Hunsaker

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Nevada procurement laws for public agencies generally require open, competitive bidding for any item that exceeds $10,000. Public agencies are also required to accept the lowest "responsive" and "responsible" bid. A "responsive bid is one which has addressed all the requirements of the bid documents. All forms must be properly completed and signed. A "responsible" bid is one in which the bidder proves the ability to perform the contract and has the resources to fulfill all the requirements of the contract. If a bidder fails to comply with all of the requirements in the contract documents, then the agency …

Induction Of Integral Membrane Pam Expression In Att-20 Cells Alters The Storage And Trafficking Of Pomc And Pc1, Giuseppe D. Ciccotosto, Martin R. Schiller, Betty A. Eipper, Richard E. Mains

Life Sciences Faculty Research

Peptidylglycine alpha-amidating monooxygenase (PAM) is an essential enzyme that catalyzes the COOH-terminal amidation of many neuroendocrine peptides. The bifunctional PAM protein contains an NH2-terminal monooxygenase (PHM) domain followed by a lyase (PAL) domain and a transmembrane domain. The cytosolic tail of PAM interacts with proteins that can affect cytoskeletal organization. A reverse tetracycline-regulated inducible expression system was used to construct an AtT-20 corticotrope cell line capable of inducible PAM-1 expression. Upon induction, cells displayed a time- and dose-dependent increase in enzyme activity, PAM mRNA, and protein. Induction of increased PAM-1 expression produced graded changes in PAM-1 metabolism. Increased expression of …

Life Sciences Faculty Research

A glasshouse experiment was conducted with plants of Phaseolus grown in liquid culture. Root growth parameters (biomass, diameter, length, growth rate, zone of cell division), root rheological components (wall extensibility, water potential yield threshold, water potential), shoot growth, carbon allocation, and abscisic acid (ABA) concentration were measured in Phaseolus acutifolius A. Gray at ambient (550 μmol mol−1) and elevated (700 μmol mol−1) atmospheric CO2 concentrations. For contrast, measurements of above‐ and belowground growth were conducted on Phaseolus vulgaris L. in the same treatments. Under nonlimiting conditions of water and nutrients, elevated CO2 increased root and shoot growth of P. acutifolius …

The Erosion Of Public Policies Which Support Workplace Justice: A Review Of The Davis-Bacon Act, Susan Foregard

UNLV Retrospective Theses & Dissertations

This thesis explores the ethical foundations of public policies which support workplace justice, using the Davis-Bacon Act as the principle example. The thesis argues that Davis-Bacon is not best considered as "pro-union" legislation, nor is cost-benefit analysis the best approach to understanding its importance. Instead, primary examination of the Davis-Bacon Act should be focused upon the policy's ethical basis and should not be sacrificed in cost-benefit analysis based upon "free market" efficiency. The Davis-Bacon Act achieves distributive justice with benefits for the general pubic, construction workers and their communities, and construction companies. The Davis-Bacon Act is defended as an effective …
