Ellis Island: The Public And Personal Representations Of The Immigrant Experience, Tara Maras Jan 2004

Ellis Island: The Public And Personal Representations Of The Immigrant Experience, Tara Maras

UNLV Retrospective Theses & Dissertations

Between 1892 and 1954, more than 12 million immigrants arrived at Ellis Island's shores for the promise of a new beginning in America. During this period of immigrant influx and in the decades to follow, anti-immigrant sentiment remained at the forefront of the collective American conscious, varying in severity, though ever present. This study compares the relationship between the personal stories of immigrants and the print media's account of immigration in Ellis Island's peak year, 1907, in an attempt to understand how storytelling, as communication, helped shape the collective immigrant experience. It also examines how the relationship contributes to U.S. …

The Reconstitutive Power Of Wovoka's Prophetic Discourse: A Rhetorical History Of The 1890 Ghost Dance Prophet, Alexander David May Jan 2004

The Reconstitutive Power Of Wovoka's Prophetic Discourse: A Rhetorical History Of The 1890 Ghost Dance Prophet, Alexander David May

UNLV Retrospective Theses & Dissertations

The tremendous influence of Wovoka, or Jack Wilson as he was commonly known, was manifested through his message of peace and renewal. The Ghost Dance Prophet of 1890 outlined a new way of life for "his people" which included every native nation, not just the Paiute. Delegations that came to hear Wovoka speak and letters he sent to the faithful spread the tenets of the religion among the indigenous people. Wovoka's rhetorical history illustrates the interplay of first persona, substantive message, and second persona as a means of transforming an audience. In addition, the parallels between the Paiute Prophet's discourse …

Attention And Memory Bias For Positive Emotional Words, Gregory P Strauss Jan 2004

Attention And Memory Bias For Positive Emotional Words, Gregory P Strauss

UNLV Retrospective Theses & Dissertations

The current study examined the relationship between attention and memory for emotional words. Theories of "basic emotion" divide emotions into positive and negative classifications, and propose that discrete categories exist within the larger positive negative dichotomy. Previous research on emotion has yet to investigate the areas of attention and memory by dividing positive/negative words into discrete emotional categories. Participants included 30 undergraduate students between the ages 18--40. Attention and Memory were examined using an Emotional Stroop task, The Emotional Verbal Learning Test, and the California Verbal Learning Test-II, respectively. Stimuli for emotional tasks are divided into five emotional word categories …

The Faith Community Response To The Bush Administrations Faith-Based Initiatives, Thomas Clark Wilson

UNLV Retrospective Theses & Dissertations

Since George W. Bush won the presidency in 2000 one of his top domestic priorities has been to elevate the role of religion in America. He is attempting to correct a perceived wrong that the federal government has hindered religious group's ability to compete on a level playing field with secular groups in acquiring funds for social service programs. Bush believes that faith-based groups hold the answer for healing society's ills. As a result his administration has set up The White House Office Of Faith-based and Community Initiatives to accomplish the goal of a more faith friendly public square; Theological, …

Community Notification Laws And Sex Offender Recidivism: A Study Of State Laws In Pre And Post Time Periods, Rachel Katherine Abrams Jan 2004

Community Notification Laws And Sex Offender Recidivism: A Study Of State Laws In Pre And Post Time Periods, Rachel Katherine Abrams

UNLV Retrospective Theses & Dissertations

In response to public concern, all states currently have some form of a sex offender community notification law. The enactment of these sex offender laws has sparked many debates regarding their implications and overall effectiveness. Sex offender community notification laws differ in their restrictiveness between states, which, in turn, may affect the overall effectiveness of these laws. The current study examines secondary data on released sex offenders before and after implementation of community notification laws. Three different states with available pre and post notification data on their released offenders in 1994 were used for analysis; Upon examination of these state …

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 …

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 …

Inadequacy, The Psychopathological Component Of Perfectionism: Validation Of The Inadequacy Scale, Brandon S Park

UNLV Retrospective Theses & Dissertations

This study tests a new measure of inadequacy and assesses its reliability and validity on a sample of 227 college students. The Inadequacy Scale (INAD) was compared to 2 measures of perfectionism: the Frost-Multidimensional Perfectionism Scale (F-MPS) and the Almost Perfect Scale-Revised (APS-R). The INAD showed equivalent or greater correlations with measures of depression, anxiety, self-esteem, and stress as compared to the full-scale measures of the F-MPS and the APS-R, as well as the subsets of their maladaptive components. The INAD was also more highly predictive of depression, anxiety, and stress (and equivalent to the F-MPS on self-esteem) than the …

Consideration Of Race/Ethnicity In Adolescent Substance Abuse Treatment Outcome Studies, Marilyn J Strada

UNLV Retrospective Theses & Dissertations

Substance use among youth continues to be a major concern in the United States. Several treatments have been developed for youth, but their external validity racially/ethnically diverse populations have not been evaluated for use in ethnic populations. The purpose of this paper was to examine the extent to which adolescent substance use treatment outcome studies have considered race/ethnicity-related factors in the design, implementation, and evaluation of treatments to determine degree of generalizability in racially/ethnically diverse populations. The findings underscored (1) discrepancies between treatment needs of racially/ethnically diverse youth and substances targeted in treatment, (2) the urgent need to focus on …

Power Aware Broadcast Trees For Sensor Networks, Sridhar Veeravalli Jan 2004

Power Aware Broadcast Trees For Sensor Networks, Sridhar Veeravalli

UNLV Retrospective Theses & Dissertations

In a sensor network with nodes distributed randomly in a two dimensional plane, the problem of constructing a power aware broadcast tree from a given source node is a difficult problem when nodes have k different levels of power. In fact, it is known that the problem of constructing a broadcast tree that minimizes total power consumption is NP-hard; We investigate the development of a good approximation algorithm for generating power reduced broadcast trees for sensor networks. We are particularly interested in the diameter of the generated broadcast tree. Both theoretical investigation and simulated results are presented. We present two …

Stratigraphic Evolution Of Las Vegas Bay, Lake Mead, Nevada: 1935--2002, Jonathan George Zybala Jan 2004

Stratigraphic Evolution Of Las Vegas Bay, Lake Mead, Nevada: 1935--2002, Jonathan George Zybala

UNLV Retrospective Theses & Dissertations

Las Vegas Bay in Lake Mead, NV provides a unique mid-scale natural laboratory to study the effects changes in lake level, sediment supply, fluvial discharge and basin physiography have had on stratigraphy of the basin. Mapping, seismic, sidescan sonar and bathymetry surveys, in conjunction with sediment cores, LPSA and 137Cs analyses were integrated to develop a temporal basin filling model for Las Vegas Bay. The evolution of the basin is divided into two periods based on lake history and stratigraphy data: an early 1935--1964, and a latter 1965--2002 period. Changes in lake history are more clearly preserved during the latter …
