The Myth Of Arrival, Zachary Jean Chartkoff Jan 2004

The Myth Of Arrival, Zachary Jean Chartkoff

UNLV Retrospective Theses & Dissertations

A collection of poems composed between the summer of 1999 and 2003. They are in the tradition of "negative ecstasy," a philosophy that the poet is nothing more than a void: in order to create, the poet requires a willing release of the ego and self, which in turn allows the poet's void to be filled with the verse. It is similar to what the Buddhists call "no mind," a method used so that works, ideas and even lives that once appeared as imperfect or failures were, by their very nature, simply unfinished acts; The process was comparable to what …

The Impact Of Dynamic Changes In Talker Amplitude On Recognition Memory For Words, Kimberly M Cramer Jan 2004

The Impact Of Dynamic Changes In Talker Amplitude On Recognition Memory For Words, Kimberly M Cramer

UNLV Retrospective Theses & Dissertations

This study investigated whether dynamic changes in the amplitude of speech were represented along with word information. An emotional manipulation was used to examine if listeners were sensitive to dynamic changes in amplitude. In Experiment 1, six talkers produced 200 phonetically balanced (PB) words with different intended emotions (e.g., joy versus sadness). Intensity measurements across time were recorded for each target word. Statistically distinct amplitude contours were obtained as a function of intended emotion. In Experiment 2, listeners judged whether each word in a list of spoken words was "new" (i.e., word was new to the list) or "old" (i.e., …

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 …
