Examination Of The Bureau Of Land Management's Implementation Of The Wild, Free-Roaming Horse And Burro Act At Red Rock National Conservation Area, Christine E. Brehm

UNLV Theses, Dissertations, Professional Papers, and Capstones

For unknown reasons horses went extinct on the North American continent approximately ten thousand years ago and were subsequently reintroduced by Spanish settlers in the 1400's. As European settlers moved westward, horses were perceived as competition for grasslands and their numbers were curtailed. Wild horses were granted Federal protection in 1959 with the passage of the 'Wild Horse Annie' law and further protected with the passage of the Wild, Free-Roaming Horse and Burro Act of 1971. Through the Department of the Interior, the Bureau of Land Management was charged with management of wild horses on public lands. Physical searches of …

Green Sea Turtle (Chelonia Mydas) Hatchlings Success: The Effects Of Artificial Lights And Other Human Impacts, Hui-Yu Tracy Liang

UNLV Theses, Dissertations, Professional Papers, and Capstones

Sea turtles appeared more than 200 million years ago in the late Triassic period. They grow very slowly, taking an average of 25 years to reach sexual maturity, with a life span averaging 40-50 years. From May to October green sea turtles (Chelonia mydas) emerge during the night and follow light cues toward the sea. Recently, beachfront development has increased hatchling mortality rate. When hatchlings emerge from nest, high densities of artificial lights lead them toward the land where they either desiccate and die, or are preyed upon. Short-wavelength high intensity light and the distance of artificial light are the …

Deposition And Uptake Availability Of Lead Shot For Waterfowl At Honeybee Pond Within The Overton Wildlife Management Area, Nevada, Usa, Jason Eckberg

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lead shot has been banned for hunting waterfowl since 1974, but lead poisoning continues to be a major problem in many waterfowl habitats. In December of 1999, soil samples were collected from the Honeybee pond at the Overton Wildlife Management area to determine the lead pellet concentration and the availability of lead shot to waterfowl. There were no shot pellets recovered from the thirty-one samples taken from the pond. Based on this information waterfowl do not appear to be exposed to lead in the pond areas at OWMA.

Two Different Soil Sampling Techniques For Assessing Soil Lead Concentrations At The Overton Wildlife Management Area, Nevada, Kristen E. Falc

UNLV Theses, Dissertations, Professional Papers, and Capstones

During the summer of 1999, soil samples were taken from the Overton Wildlife Management Area (OWMA), located in the Moapa Valley of Clark County, Nevada. Although lead shot has been banned for the hunting of waterfowl since 1986, it is still legal for upland game hunting. The field sampled serves primarily as a dove hunting area and is cultivated. A large sample size was taken to indicate the short-term effects of the deposition of lead shot in the area and a small sample size, the long-term. Lead shot was recovered from 64% of the small samples and the estimated concentration …

Special Event Recycling: The Future Of Unlv's Recycling Program, Katherine A. Baker

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current recycling program on the University of Nevada Las Vegas (UNLV) campus does not have a special event recycling aspect. The purpose of this study was to develop a special event recycling program and make recommendations of how to effectively implement it on the UNLV campus. In order to develop this special event recycling program data was collected through surveys and a pilot study. The data collected was then used to formulate recommendations. Recycling two different kinds of events, a walk and a concert tested those recommendations. Waste stream analyses were done on each event. The waste stream diversion …

A Study Of Parental Characteristics And School Choice, Chia-Lin Hsieh

Dissertations

Parental choice of schools has been a hot political issue for more than a decade and has become a cornerstone of federal educational policy. This study investigated the relationship between parental characteristics and school choice, and whether the decision to choose schools is related to family characteristics, school characteristics, parental beliefs, and/or parental satisfaction.

This study used existing national data that were gathered by the National Center for Education Statistics (NCES) and were extracted from the School Safety and Discipline (SS&D) component o f the 1993 National Household Education Survey (NHES:93). 12,680 parents with children in 3rd through 12th grades …

Practitioners’ Perspectives On Alternatives To The Paper-Based System For Preventing Welfare Fraud, Timothy Jerome Cole

Dissertations

Federal agencies have begun to devote greater attention to detecting welfare fraud. This dissertation reviews three proposed alternatives to the current Paper- Based system for preventing welfare fraud, namely, the Paper-Based system with Fingerprint Imaging, Electronic Benefits Transfer (EBT), and EBT with Fingerprint Imaging. It also examines the policy implications likely to result from implementation of these various systems.

Practitioners were randomly selected from agency directories and mailed a survey. Information was sought on their socioeconomic background, professional affiliations, and opinions on several welfare fraud detection systems.

Statistically significant differences in their responses resulted from differences in their socioeconomic backgrounds, …

Precision Measurement Of The Spin Structure Of The Proton And The Deuteron, Frank R. Wesselmann

Physics Theses & Dissertations

Experiment E155 at the Stanford Linear Accelerator Center measured the spin structure functions g1 and g2 of the proton and deuteron using deep inelastic scattering of 50 GeV polarized electrons from dynamically polarized, solid ¹⁵NH₃ and ⁶LiD targets. Three independent spectrometers, covering a large kinematic region, 0.014 < x_Bjorken < 0.9 and 1 < Q² < 40 (GeV /c)^2, detected 200 million events. A fully self-consistent and statistically sound approach to calculating radiative corrections was developed, providing well-defined statistical errors for the E155 data set. Also, a comprehensive fit to the global data set was created which simultaneously …

The Noesy Jigsaw: Automated Protein Secondary Structure And Main-Chain Assignment From Sparse, Unassigned Nmr Data, Chris Bailey-Kellogg, Alik Widge, John J. Kelley Iii, Marcelo J. Berardi, John H. Bushweller, Bruce Randall Donald

Dartmouth Scholarship

High-throughput, data-directed computational protocols for Structural Genomics (or Proteomics) are required in order to evaluate the protein products of genes for structure and function at rates comparable to current gene-sequencing technology. This paper presents the Jigsaw algorithm, a novel high-throughput, automated approach to protein structure characterization with nuclear magnetic resonance (NMR). Jigsaw consists of two main components: (1) graph-based secondary structure pattern identification in unassigned heteronuclear NMR data, and (2) assignment of spectral peaks by probabilistic alignment of identified secondary structure elements against the primary sequence. Jigsaw's deferment of assignment until after secondary structure identification differs greatly from traditional approaches, …

Restricted Delegation: Seamlessly Spanning Administrative Boundaries, Jon Howell, David Kotz

Dartmouth Scholarship

Historically and currently, access control and authentication is managed through ACLs. Examples include:

• the list of users in /etc/password, the NIS passwd map, or an NT domain

• permissions on Unix files or ACLs on NT objects

• a list of known hosts in .ssh/known hosts

• a list of IP addresses in .rhosts (for rsh) or .htaccess (http)

The limitations of ACLs always cause problems when spanning administrative domains (and often even inside administrative domains). The best example is the inability to express transitive sharing. Alice shares read access to object X with Bob (but not access to …

Multiple Source Pools And Dispersal Barriers For Galápagos Plant Species Distribution, J. Alan Yeakley, John F. Weishampel

Environmental Science and Management Faculty Publications and Presentations

We reexamined geographic factors explaining the number of plant species on islands in the Galápagos Archipelago. We hypothesized that plant species richness (S) was related to the number of source pools and that plant species dispersal preferentially followed direct, oceanic pathways. To test different dispersal pathways from multiple source pools, the total number of islands within a given dispersal radius (i) was posed as the sum of the number of line-of-sight islands (C_i) and of the number of islands without line-of sight connection (B_i). In partial regression analyses, controlling for nearest island area (A₂) …

Water Supply Sustainability Through Water Banking, Linda I. Gordan

Water Resources Professional Project Reports

Until relatively recently, the preferred approach to satisfying the water needs of growing communities has been to develop untapped supplies. As new water-supply sources have become less accessible, and as developing then has become more expensive and less acceptable environmentally, managing demand and enabling voluntary water reallocation have taken on increasing importance. Demand management and water marketing could be very important in coping with increasing demand and limited supplies, both because they promote efficiency and because they enable a considerable amount of flexibility in water resource management.

Literary And Poetic Performance In Plato's Laws, Gerard Naddaf

The Society for Ancient Greek Philosophy Newsletter

Plato’s evaluations of the written and spoken word are complex, even ambiguous. On the one hand, he clearly privileges the give-and-take oral conversation as the paradigm for philosophical discussion, and on the basis of this paradigm he offers strong critiques of the written word, notably in the Phaedrus and Letter 7. On the other hand, he is a most famous enemy of the oral performance of poetry − notwithstanding the fact that in the Republic he gives ‘music’ a prominent place in education. When we turn to the Laws, we encounter another aspect or dimension of Plato’s thinking about the …

Divalent Metal Binding Properties Of The Methionyl Aminopeptidase From Escherichia Coli, Ventris M. D'Souza, Brian Bennett, Alicja J. Copik, Richard C. Holz

Physics Faculty Research and Publications

The metal-binding properties of the methionyl aminopeptidase from Escherichia coli (MetAP) were investigated. Measurements of catalytic activity as a function of added Co(II) and Fe(II) revealed that maximal enzymatic activity is observed after the addition of only 1 equiv of divalent metal ion. Based on these studies, metal binding constants for the first metal binding event were found to be 0.3 ± 0.2 μM and 0.2 ± 0.2 μM for Co(II)- and Fe(II)-substituted MetAP, respectively. Binding of excess metal ions (>50 equiv) resulted in the loss of ∼50% of the catalytic activity. Electronic absorption spectral titration of a 1 …

Repellents To Reduce Cable Gnawing By Wild Norway Rats, Stephen A. Shumake, Ray T. Sterner, Stanley E. Gaddis

United States Department of Agriculture Wildlife Services: Staff Publications

Rodents gnaw communications and power cables, resulting in service interruptions, fires, and other safety concerns. Commensal rodents such as the Norway rat (Rattus norvegicus) have been implicated in many of these situations. Two chemical repellents (capsicum oleoresin+apsaicin and denatonium benzoate) at 2.0% mass/mass concentrations in a polybutene carrier (Indopol-controlw) ere evaluated for repellent efficacy compared to a plastic mesh physical barrier material (Vexa*) and the polybutene carrier (placebo) alone using groups of individually caged wild Norway rats. The materials were applied to short lengths of communications cable (RG-8U) with the repellents enclosed in electrical shrink tubing around the …

Long-Term Spatial Stability Of Coyote (Canis Latrans) Home Ranges In Southeastern Colorado, Ann M. Kitchen, Eric M. Gese, Edward R. Schauster

United States Department of Agriculture Wildlife Services: Staff Publications

Long-term stability of territorial boundaries has not been well documented in canids. To evaluate the prevalence of long-term spatial stability of coyote (Canis latrans) home ranges, we compared the overlap of territorial boundaries and the spatial distribution of telemetry locations of packs in southeastern Colorado. From August 1983 to July 1988 (period l), 16 coyotes from six packs were radio-tracked. From April 1996 to August 1997 (period 2), 12 coyotes from six packs were captured and tracked in the same area. Mean percentage of overlap of pack ranges was 89.8 ± 8.3% (+SD) for period 1 ranges over …

The Effect Of Advisement And Competition On Transfer, Advisor Use, And Attitude Toward Mathematics Using A Computer-Based Simulation Game, Richard Van Eck

Teaching, Leadership & Professional Practice Faculty Publications

This study looks at the roles that competition and context of advisement play in transfer, advisor use, attitude toward mathematics, and attitude toward instruction in a computer-based simulation game that required the use of mathematics skills. It is concluded that for transfer training, non-competitive simulation games might be the best choice, better at least than simulation games that include a time-pressure factor. Advisement appeared to be a good way to promote transfer and positive attitude toward mathematics and instruction, the latter two of which can indirectly promote future performance.

Solid-State Deuterium Nuclear Magnetic Resonance Of The Methyl Dynamics Of Poly(Alpha-Methylstyrene) And Polymethylphenylsilane, Robert D. O'Connor, Eric J. Ginsburg, Frank D. Blum

Chemistry Faculty Research & Creative Works

The methyl-d3 dynamics of two relatively similar polymers, poly(alpha-methylstyrene) (PAMS-d3) and polymethylphenylsilane (PMPS-d3), are investigated via deuterium NMR relaxation experiments. Our analysis of the relaxation data uses the entire solid-echo spectra to maximize the precision of the experiments with regard to the information available on the methyl dynamics. The analysis is novel in that it does not use M[infinity] or M0 to fit the relaxation data. Additionally, the three-site symmetric jump model is shown to not have an observable azimuthal angular dependence for T1 relaxation. The methyl dynamics are quantified with taum, sigma, and f which are the log-average correlation …

Comparative Analysis Of Three Remediation Technologies For The Clean Up Of Petroleum Contaminated Groundwater, Thomas Bouck

UNLV Theses, Dissertations, Professional Papers, and Capstones

This paper will compare three remediation technologies to determine which is the most efficient and effective remediation treatment for a petroleum contaminated groundwater site. The three remediation technologies are in situ bioremediation, in situ air sparging, and air stripping with carbon filtration. This comparison will be done through a literature review. It will take the information derived from the review and then apply it to the information about a petroleum contaminated groundwater location. The comparative analysis will consist of these parameters permit requirements, clean up time, operating and maintenance, and geological factors.

These factors permit requirements, cleanup time, and operating …
