Survival Of Enterococcal And Streptococcal Species In Natural Waters, Kameron L Entrekin Jan 2004

Survival Of Enterococcal And Streptococcal Species In Natural Waters, Kameron L Entrekin

UNLV Retrospective Theses & Dissertations

Survival capabilities of indicators of fecal pollution, such as enterococci, in the natural aquatic environment are of particular importance in proper management of a watershed. The Las Vegas Wash (LVW) is a naturally occurring and engineered tributary to Lake Mead; The ability of the Las Vegas Wash to sustain microbial viability over time was assessed utilizing ATCC cultures and environmentally isolated species. Wash water samples were autoclaved and seeded with known concentrations of enterococci. Microcosms were incubated at 25°C, and decline was measured by heterotrophic plate counts at specific time intervals. Results of survival studies using ATCC derived species showed …

Evaluation Of The Perceptual Magnet Effect And Categorical Perception For Musical Timbre, Melissa Kay Griffith Jan 2004

Evaluation Of The Perceptual Magnet Effect And Categorical Perception For Musical Timbre, Melissa Kay Griffith

UNLV Retrospective Theses & Dissertations

Recent auditory research has raised fundamental questions about the perceptual magnet effect (PME), where discrimination performance is poorer for stimuli that approach best exemplars of a phonetic category. It has been suggested that the effect reflects inter-categorical comparisons, and might not generalize to nonspeech. Three experiments addressed these concerns. In Experiment 1 prototype and non-prototype stimuli were determined from goodness ratings of synthesized (violin) timbres varying in center frequencies of F1 and F2 formants. Experiment 2 evaluated for a PME using discrimination data, and influences from other categories by comparing goodness ratings from stimuli in prototype, non-prototype, and no context …

Pathological Gambling And Substance Abuse In The Las Vegas Arrestee Population, Jeffrey Michael Groebner Jan 2004

Pathological Gambling And Substance Abuse In The Las Vegas Arrestee Population, Jeffrey Michael Groebner

UNLV Retrospective Theses & Dissertations

There has been extensive literature on the nature of pathological gambling and substance abuse on criminal offending; however, most of what is known about these disorders stem from clinical populations and the general population. Both of these populations differ from arrestee populations; therefore, our understanding about the disorders remains limited. This is a study among the arrestee population utilizing data collected in Las Vegas detention centers during a federally funded research project that monitors the extent and nature of drug abuse. In addition to the program, a Gambling Addendum was administered to all willing participants; Findings support a greater prevalence …

Specialization In The Criminal Careers Of Sex Offenders, Jodi K Olson Jan 2004

Specialization In The Criminal Careers Of Sex Offenders, Jodi K Olson

UNLV Retrospective Theses & Dissertations

Recent public policy has been implemented with the assumption that sex offenders are highly motivated and tend to exhibit specialization and compulsivity in their offending patterns. Past research has not been able to confirm or invalidate this assumption, and has reflected many inconsistencies when drawing conclusions about sex offender profiles and career trajectories; Drawing upon a national sample of offenders, the current study examines the degree of specialization in the criminal careers of sex offenders and other groups of offenders. Results from the adjacent specialization analyses of the general offense categories indicated that sex offenders are among the least specialized …

Determination Of Reliability Indices For Congestion On Urban Arterial Streets, Venu Parimi Jan 2004

Determination Of Reliability Indices For Congestion On Urban Arterial Streets, Venu Parimi

UNLV Retrospective Theses & Dissertations

Motorists tend to accept certain levels of delay during peak traffic conditions, but become increasingly agitated when the travel times increase unpredictably due to incidents on roadways. The objective of this thesis is to develop a reliability index quantifying the spatial and temporal distribution of traffic congestion on urban arterial streets. Delays caused due to recurrent and non-recurrent congestion need to be differentiated. Two approaches for estimating road network reliability are proposed to quantify delays due to recurrent and non-recurrent congestion. These indices are expressed as functions of operating speed and travel time respectively. A case study using urban arterial …

Self-Stabilizing Inter-Domain Policy Routing, Venkatakrishnan Trichy Ramasubramanian Jan 2004

Self-Stabilizing Inter-Domain Policy Routing, Venkatakrishnan Trichy Ramasubramanian

UNLV Retrospective Theses & Dissertations

As the complexity of the networked systems increases, the likelihood of experiencing unanticipated faults grows. Self-stabilization is the most general technique to design fault tolerant systems. This paradigm was introduced by Dijkstra in 1974. A self-stabilizing system guarantees that starting from an arbitrary state, the system converges to a legal state in a finite number of steps and remains in a legal state until another fault occurs. Such a system after any unexpected perturbation eventually recovers without any outside intervention; The goal of this thesis research is to design a self-stabilizing Inter Domain Policy Routing Algorithm in order to make …

Balanced Biosocial Theory For The Social Sciences, Michael A Restivo Jan 2004

Balanced Biosocial Theory For The Social Sciences, Michael A Restivo

UNLV Retrospective Theses & Dissertations

Evolutionary theory is the unquestioned paradigm for all biological sciences and is gaining acceptance in many of the social sciences, predominantly psychology and anthropology. Sociology, as a discipline, has failed to embrace evolutionary theory and remains uninformed about the most powerful scientific theory of living things: the theory of evolution by Darwinian selection. Traditional sociological theory is based largely on empirically questionable ideas about human development, behavior, and psychology, and often contradicts fundamental knowledge about evolution. As such, it often fails to contribute to a coherent and progressive corpus of sociological knowledge. Biosocial theories present a compelling alternative to the …

Client Perceptions Of Child Protective Services, Jerry L Rohleder Jan 2004

Client Perceptions Of Child Protective Services, Jerry L Rohleder

UNLV Retrospective Theses & Dissertations

Inductive research methods are used to explore client perceptions of Child Protective Services in Clark County, NV. Interviews with fifteen persons who had experiences with CPS are discussed. The small sample limits the generalizability of the results, but there are indications the type of help offered or received is not always what a particular client perceives is needed, they are dissatisfied with the way they are treated, and they are not aware of any mechanisms available to register disagreements. Many of the clients express feelings of alienation and anomie. Suggestions for improving this relationship include changes in reporting procedures, showing …

The Volcanology And Petrogenesis Of The Northern Lunar Crater Volcanic Field, Nye County, Nevada, Elizabeth Kay Stickney Jan 2004

The Volcanology And Petrogenesis Of The Northern Lunar Crater Volcanic Field, Nye County, Nevada, Elizabeth Kay Stickney

UNLV Retrospective Theses & Dissertations

The Northern Lunar Crater Volcanic Field (NLCVF) is located along the axis of the Great Basin in Nye County, Nevada. This area of Pliocene to Recent cinder cones, maars and alkali basalt lava flows represents the northern terminus of the Death Valley-Pancake Range Basalt Zone. Basalts from this area can be divided into two distinct groups, those of trace element enrichment relative to Ocean Island Basalt, and those of trace element depletion relative to Ocean Island Basalt, with each group containing a range of compositions. The NLCVF represents a simple volcanic area, with basalts formed by differing degrees of partial …

A System Model For Source Water Assessment In The Las Vegas Valley, Silvia Albuquerque Jan 2004

A System Model For Source Water Assessment In The Las Vegas Valley, Silvia Albuquerque

UNLV Retrospective Theses & Dissertations

The 1996 amendment to the Safe Drinking Water Act of 1974 created the Source Water Assessment Program (SWAP) with an objective to evaluate potential sources of contamination to drinking water intakes. The development of a Source Water Assessment Plan for Las Vegas Valley surface water runoff into Lake Mead is important since it will guide future work on source water protection of the main source of water; Once the vulnerability of the intake was determined, a tool was developed to help with source water assessment, using the system dynamics model Stella. This model calculates the average vulnerability of the intake, …

Vietnam And The More Flags Campaign, 1964--1965: The Search For American Allies In The Commonwealth, Becky L Bruce Jan 2004

Vietnam And The More Flags Campaign, 1964--1965: The Search For American Allies In The Commonwealth, Becky L Bruce

UNLV Retrospective Theses & Dissertations

In April 1964, the United States initiated the More Flags campaign in an attempt to establish a western coalition force and diplomatic support system for the South Vietnamese government and for American intervention against the North. Three of the most heavily courted nations were the Commonwealth members of Australia, Great Britain, and Canada. This first in-depth study of this diplomatic effort and the comparative response of these Commonwealth nations provides insight into the U.S. efforts at coalition building, the essentially unilateralist and nationalist nature of U.S. foreign policy, and the varying U.S. relationships with these three important members of the …

Metricizing' Non-Metric Craniofacial Traits: Application Of Three Dimensional Geometric Morphometric Analysis To Ancestral Identification, Summer Joy Decker Jan 2004

Metricizing' Non-Metric Craniofacial Traits: Application Of Three Dimensional Geometric Morphometric Analysis To Ancestral Identification, Summer Joy Decker

UNLV Retrospective Theses & Dissertations

Non-metric traits are commonly used by anthropologists to distinguish between groups for such things as age, sex, and even ancestry. However, many non-metric traits cannot be measured with traditional osteological tools. While these traditional methods are useful, they do not take individual variation into account. This thesis uses geometric morphometric coordinate data to 'metricize' such traits and to evaluate their accuracy of correctly assigning unknown individuals to statistically defined groups; A 3-D digitizer was used to collect data from 39 craniofacial landmarks to capture the form of several phenotypic facial characteristics. The sample consisted of individuals from four different geographic …

Gis Analysis Of The Pre And Post-Diversion Water Balances In Owens Valley, California, Anna Corinne Draa Jan 2004

Gis Analysis Of The Pre And Post-Diversion Water Balances In Owens Valley, California, Anna Corinne Draa

UNLV Retrospective Theses & Dissertations

Owens Valley, California is located at the western border of both the Basin and Range and Great Basin Provinces. The valley is hydrologically closed; the only outflow for ground and surface waters is evaporation to the atmosphere. Los Angeles Department of Water and Power (LADWP) began diverting water from Owens Valley in 1913 and has steadily increased the amount of water removed from the valley since then; LADWP has always assumed that the hydrologic system as it existed in 1913 was in equilibrium with modern climate. This study develops a geographical information systems (GIS) based model of Owens Valley to …
