Heat Shock Proteins As Indicators Of Environmental Stress, Arthur Louis Castle Jan 1997

Heat Shock Proteins As Indicators Of Environmental Stress, Arthur Louis Castle

UNLV Retrospective Theses & Dissertations

In order to determine whether heat shock proteins (HSP) can be used as indicators of environmental stress in the mammalian organism Peromyscus leucopus, three doses of each of two chemical stresses, cadmium chloride and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), were given intraperitoneally for 14 days. Proteins extracted from liver samples were compared by one-dimensional gel electrophoresis to liver protein samples from heat shocked and control animals. HSPs of 105,78, and 43 kDa were cadmium inducible. Non-heat shocked cadmium inducible proteins of 118, 55, and 47 kDa were seen. 2,4,5-T induced an increase in a 91 kDa protein. Low level cadmium induction of …


Attorney Advertising: The Effect On Juror Perceptions And Verdicts, Stephanie Moore Myers Jan 1997

Attorney Advertising: The Effect On Juror Perceptions And Verdicts, Stephanie Moore Myers

UNLV Retrospective Theses & Dissertations

This study examined the effect of attorney television advertising on jurors. Southern Nevada jurors who had served on personal injury and malpractice trials were sent survey questionnaires designed to elicit juror attitudes about attorneys and attorney advertising. The response rate was 53.3%; The major finding was that although respondents generally do not like lawyer television advertising, it does not affect their trial verdicts unless jurors are actually confronted with a plaintiff's lawyer who advertises on television; then, jurors tend to vote for the defense. There is strong sentiment that the law should be changed to limit jury awards. Advertising lawyers …


Provenance And Tectonic Significance Of The Lower Paleozoic Douglas Conglomerate, Northern Churchill Mountains, Antarctica, Susan Kay Panttaja Jan 1997

Provenance And Tectonic Significance Of The Lower Paleozoic Douglas Conglomerate, Northern Churchill Mountains, Antarctica, Susan Kay Panttaja

UNLV Retrospective Theses & Dissertations

The Douglas Conglomerate in the Churchill Mountains of Antarctica is a polymictic, unconformity-bounded unit whose age is poorly constrained between Late Cambrian and Devonian. Its source areas were local, including outcrops of Cambrian Shackleton Limestone, the craton of Greater Antarctica, and perhaps, terranes that lay outboard of the craton but subsequently were dispersed along transform faults; Petrographic analyses suggest a recycled orogen provenance for the Douglas Its depositional basin may have developed within a fold-and-thrust belt or along an active transform fault. Subsequent tectonism dismembered the formation, but its composition suggests the basin had fault-controlled margins walled within Shackleton Limestone …

The Effects Of Early Intervention On Young Handicapped Children Who Are Nonverbal Or Have Limited Expressive Language Skills, Joyce Mott Anderson

UNLV Retrospective Theses & Dissertations

The purpose of this study was to investigate the impact of early intervention services on sixteen young handicapped children who were nonverbal or exhibited limited expressive verbal skills. It was proposed that these children would make gains in all areas of development including cognitive, receptive language, expressive language, fine motor, gross motor, self-help, and social/emotional as a result of carefully and systematically planned intervention. The subjects in this study had expressive language delays ranging from eight to thirty-three months. All children participated in an early intervention learning center that provided services noncategorically using a wholistic and transdisciplinary approach; The findings …


A Matter Of Faith: A Study Of The Muddy Mission, Monique Elaine Kimball Jan 1997

A Matter Of Faith: A Study Of The Muddy Mission, Monique Elaine Kimball

UNLV Retrospective Theses & Dissertations

Leonard J. Arrington wrote about the Mormon development of the Great Basin from 1847 to 1900 in Great Basin Kingdom (1966). He summarized Mormon economic ideals in seven principles which served as the basis of his argument about their success in the Great Basin; The Muddy Mission, established on the Muddy River (Nevada) in 1865, served three purposes, foremost was cotton production. Church leaders believed that the successes experienced in Utah would be repeated in the southern regions. Unfortunately, by 1871 politics and economics ended any successes the Muddy Mission had; Arrington's principles represent a Mormon's ethnographic statement about the …

Stratigraphy And Depositional Environments Of Lower And Middle Cambrian Strata In The Lake Mead Region, Southern Nevada And Northwestern Arizona, Joseph Kirk Hardy Jan 1997

Stratigraphy And Depositional Environments Of Lower And Middle Cambrian Strata In The Lake Mead Region, Southern Nevada And Northwestern Arizona, Joseph Kirk Hardy

UNLV Retrospective Theses & Dissertations

The stratigraphy and depositional systems revealed within the Lower to Middle Cambrian Tapeats Sandstone-Pioche Shale-Lyndon Limestone-Chisholm Shale succession were studied between the easternmost limit of Cretaceous overthrusting in southern Nevada and the western edge of the Colorado Plateau in northwestern Arizona. Nine intergradational lithofacies were distinguished based on a rich suite of sedimentary structures, including lenticular-, wavy-, and flaser-bedding, wrinkle marks, herringbone cross-stratification, convolute bedding, primary current lineations, interference ripple marks, bird's eye structures, thrombolites, intraformational conglomerates, oncoids, cryptalgal laminites, and Arenicoloides, Corophioides, and Skolithos ichnofossils. The collective presence of these structures indicates that Lower and Middle Cambrian rocks in …


Voices Of Three African American Female College Presidents: A Qualitative Study Of Their Journeys, Maria Teresa Alves Williams Jan 1997

Voices Of Three African American Female College Presidents: A Qualitative Study Of Their Journeys, Maria Teresa Alves Williams

UNLV Retrospective Theses & Dissertations

There are many prevailing myths that have influenced society's perception of Black women. As a result, a tradition of negativity surrounds African American women in American society. It is these "negative perceptions and misinterpretation of African American women's behavior that found its way into colleges and universities" (Myers, 1991, p. 9). Unlike White women, and Black men, Black women in academe experience double jeopardy; race and gender biases (Gregory, 1995; Myers, 2002). Research on Black women has found that they are concentrated at the lowest academic ranks, non-tenured, paid less than their male and White female counterparts, and promoted at …


College Students' Image Of Nursing As A Career Choice, Diana Teresa Mendez Jan 1997

College Students' Image Of Nursing As A Career Choice, Diana Teresa Mendez

UNLV Retrospective Theses & Dissertations

This thesis is a study of the image of nursing among college students. It has been inferred that the poor image of nursing negatively impacts on recruitment into the profession. A convenience survey of two groups of college students was instituted to determine the image of nursing in relation to an ideal career, and to discover if there are factors which make the choice of nursing as a career more likely. The responses of a group of 163 nonnursing students were compared to the responses of a group of 93 nursing students; This survey indicated that the image of nursing …


Nurse And Patient Perception Of Stressors Associated With Coronary Artery Bypass Surgery, Rosemary Puetz Jan 1997

Nurse And Patient Perception Of Stressors Associated With Coronary Artery Bypass Surgery, Rosemary Puetz

UNLV Retrospective Theses & Dissertations

This study investigated the relationships between the nurses' and patients' perception of stressors associated with coronary artery bypass surgery. The population of the study consisted of two groups: (1) patients recovering from coronary artery bypass surgery, and (2) registered nurses providing the care for the coronary artery bypass patient. The instrument utilized was the Cardiac Surgery Stressor Scale. The research data was analyzed by the following statistical techniques: (1) descriptive methods, (2) Pearson Product Moment Correlation Coefficient, and (3) Student t-test. Nurses consistently rated the stressors higher than the patients. The results suggest that nurses need to develop a method …


Grasp--A Language To Facilitate The Synthesis Of Parallel Programs, Todd Alan Gross Jan 1997

Grasp--A Language To Facilitate The Synthesis Of Parallel Programs, Todd Alan Gross

UNLV Retrospective Theses & Dissertations

In the context of this thesis, the name Grasp subsumes three distinct but highly interrelated projects. First of all, Grasp is a programming language that allows the user to define properties of graph-theoretic objects by using high-level nonprocedural descriptions called specifications. Second, Grasp is a translator that converts specifications to standard sequential C functions. Finally, Grasp is a model of computation that has been left largely uninvestigated despite possessing several advantageous properties. Each of these aspects of Grasp is described in a contextually clean and detailed manner, but in the end the theoretical aspects of Grasp are espoused over the …


The Muddy Creek Formation: Depositional Environment, Provenance, And Tectonic Significance In The Western Lake Mead Area, Nevada And Arizona, Allan J. Scott Jan 1997

The Muddy Creek Formation: Depositional Environment, Provenance, And Tectonic Significance In The Western Lake Mead Area, Nevada And Arizona, Allan J. Scott

UNLV Retrospective Theses & Dissertations

In the River Mountains, the Muddy Creek Formation is informally divided into four members; the River Mountain conglomerate, the Boulder Basin conglomerate, the lakeshore member, and The Cliffs member; Clasts in the Muddy Creek Formation are composed of andesite, dacite, basalt, rhyolite, quartz monzonite, and granite. Paleocurrent data for the basal River Mountain conglomerate suggest that the transport direction was to the southeast, parallel to the regional strike of high-angle normal faults. The River Mountain conglomerate may have been transported along the axes of basins that were controlled by these faults; The River Mountain conglomerate was probably deposited during a …


The Effect Of Wetsuit Leg Coverage On Swimming Speed And Selected Physiological Measures, Peggy-Lynn Dursthoff Jan 1997

The Effect Of Wetsuit Leg Coverage On Swimming Speed And Selected Physiological Measures, Peggy-Lynn Dursthoff

UNLV Retrospective Theses & Dissertations

The effect of wetsuit leg coverage on swimming speed and body temperatures was investigated by having 10 triathletes swim 1500 meters 4 times in two different water temperatures in short sleeved wetsuits. Subjects swam twice in a full wetsuit which covered the leg to the ankle and twice in a wetsuit which ended at mid-thigh. Four skin temperatures, esophageal temperature and swimming speed were measured during each swim. A 2 x 2 analysis of variance was performed on each dependant variable. In addition a 2 x 2 Manova was done to test for differences in the means of all skin …


Rhetorical Byron: An Interpretation Of His Historical Tragedies, Vicki Maxine Bertolino Jan 1997

Rhetorical Byron: An Interpretation Of His Historical Tragedies, Vicki Maxine Bertolino

UNLV Retrospective Theses & Dissertations

This thesis shows that Lord Byron's history plays in particular may be works of fiction, but they may also be viewed as rhetorical discourses because they can be seen as direct responses to the complex social and political issues emerging from both the Industrial and French Revolutions. This claim was demonstrated by using a contemporary concept of rhetoric, Lloyd Bitzer's "The Rhetorical Situation." The major findings of this study were that Lord Byron was a rhetorician because his plays reflected a specific rhetorical situation, yet he also failed as a rhetorician because of his selection of an abstract, idealized audience …


Effects Of Duct Source And Termination Impedance On The Acoustic Response Characteristics Of Duct Elements, Prabhanjan Mysore Jan 1997

Effects Of Duct Source And Termination Impedance On The Acoustic Response Characteristics Of Duct Elements, Prabhanjan Mysore

UNLV Retrospective Theses & Dissertations

The objective of the thesis is to study the effects of termination of an air duct on the acoustic response characteristics of the elements in the duct system. The end reflections due to the mis-match of the acoustic impedance at the termination affect the acoustic characteristics of the duct elements; The ducts of the duct system, terminating into atmosphere abruptly, like the HVAC ducts with diffusers, provide reflective termination. With this type of termination much of the sound energy in lower frequencies is reflected. This sets up standing sound waves inside the duct. The analytical methods to calculate the insertion-loss, …


Mexican Identity In Clark County, Nevada: A Visual Ethnohistory, 1829-1960, Corinne Escobar Jan 1997

Mexican Identity In Clark County, Nevada: A Visual Ethnohistory, 1829-1960, Corinne Escobar

UNLV Retrospective Theses & Dissertations

Mexicans were present in southern Nevada since 1829 but their history is not well documented. Often their cultural identity was misrepresented in several Nevada histories. This thesis establishes a written and photographic documentation of the Mexican identity population in southern Nevada between 1829 and 1960; A four-fold typology that expands the definition of ethnicity to include the nature of interethnic relations between two or more ethnic groups is applied to identify the relationships experienced between those of Mexican identity and Euro-Americans. This model, known as the four types of ethnicity, describes interactive behavior as being complementary, competitive, confrontational, or colonial …


Experimental Determination Of Heat Transfer And Fluid Flow Over Drift-Emplaced Canisters, Satish Pattisam Jan 1997

Experimental Determination Of Heat Transfer And Fluid Flow Over Drift-Emplaced Canisters, Satish Pattisam

UNLV Retrospective Theses & Dissertations

Drift-emplaced waste canisters are under consideration for the long-term storage of high level spent fuel in the proposed underground repository at Yucca Mountain. These canisters will be placed on pedestals above the floor of the drifts and exchange heat with the walls of the drift and with air circulating through the repository. To assess the requirements of the repository ventilation system, values of the dimensionless convective heat transfer coefficient and the pressure drop across individual canisters were measured in an experimental model of the drift. The results were curve-fitted as functions of the spacing between the canisters and the Reynolds …

Leadership Challenges Encountered By Elementary School Principals In The Process Of Creating, Implementing, And Sustaining Shared School Visions In Clark County, Nevada, Elementary Schools, David Allen Price Jan 1997

Leadership Challenges Encountered By Elementary School Principals In The Process Of Creating, Implementing, And Sustaining Shared School Visions In Clark County, Nevada, Elementary Schools, David Allen Price

UNLV Retrospective Theses & Dissertations

Creating, implementing, and sustaining a shared vision is a complicated task for any leader. The Elementary School Division of the Clark County School District (CCSD) expects elementary school principals not only to develop a shared vision for their schools, but also to implement and sustain this shared vision with the aid of their constituencies--other administrators, staff, students, parents, and the community-at-large. Leaders, in this case principals, generally are responsible for developing a shared vision; The concept of visionary leadership has been defined in the literature, and principals can be tested to determine the degree to which they align themselves with …


A Cause-And-Effect Relationship Between Leadership And Corporate Culture: An Educational Perspective, Shane C Blum Jan 1997

A Cause-And-Effect Relationship Between Leadership And Corporate Culture: An Educational Perspective, Shane C Blum

UNLV Retrospective Theses & Dissertations

The purpose of this exploratory research was to examine the relationship between the corporate culture of four-year hospitality management programs and the leadership styles of individuals responsible for leading these programs. Separate instruments were used to survey faculty and program heads of four-year hospitality management programs in an attempt to explore numerous research questions. Certain questions focused on the leadership styles of individuals in positions of authority within the program's administration. Other questions were geared toward evaluating the strength of the program's culture measured along a number of criteria. By examining these questions a theoretical relationship between leadership and culture …


Mass Spectroscopy Of Molecules Following Deep-Core-Shell Photoexcitation, David Linnemann Hansen Jan 1997

Mass Spectroscopy Of Molecules Following Deep-Core-Shell Photoexcitation, David Linnemann Hansen

UNLV Retrospective Theses & Dissertations

The relaxation dynamics of HCl, DCl, H{dollar}\sb2{dollar}S, and D{dollar}\sb2{dollar}S following photoexcitation in the vicinity of the Cl, and S K-shell thresholds ({dollar}\sim{dollar}2.8 keV for Cl, {dollar}\sim{dollar}2.5 keV for S) were studied by means of ion time-of-flight mass spectroscopy using monochromatic synchrotron radiation. In all cases, the onset of pre-edge core-shell photoionization precedes the formation on resonance of a significant amount of neutral hydrogen as well as post-collision-interaction effects above threshold. At the lowest resonant excitation to the 6{dollar}\sigma\sp{\*}{dollar} antibonding orbital in HCl, almost half of the excited molecules decay by emission of a neutral H atom, mostly in coincidence with …


A Critical Analysis Of Barriers That Inhibit Latino Parent Involvement As Students Make The Transition From Esl To Mainstream Classrooms, Linda R Skroback-Heisler Jan 1997

A Critical Analysis Of Barriers That Inhibit Latino Parent Involvement As Students Make The Transition From Esl To Mainstream Classrooms, Linda R Skroback-Heisler

UNLV Retrospective Theses & Dissertations

The purpose of this study was to explore the perspectives of Latino families concerning parent involvement roles while their children made the transition from ESL to mainstream classrooms. Three families were interviewed individually at eight week intervals for ten months. Using critical theory as a framework, data sources established three themes of status quo describing parents' knowledge and beliefs during prior experiences, ESL class, and during the year their fourth grade children were mainstreamed. Initially coded by constant comparative methods, a second and critical analysis of data uncovered the fourth theme: barriers encountered by Latino parents during the mainstream year. …


An Ethnography Of Homeless Men In Las Vegas, Kurt B Borchard Jan 1997

An Ethnography Of Homeless Men In Las Vegas, Kurt B Borchard

UNLV Retrospective Theses & Dissertations

Most recent research on homeless men (1) uses quantitative methods, (2) frequently blames homeless men for being homeless, and (3) does not consider the different meanings different groups assign to homelessness. These studies cannot address (1) the usefulness of other methods in studying homelessness, (2) what other factors beyond personal problems may contribute to homelessness, and (3) how different groups in different locales view the condition; In this dissertation I use qualitative methods first to think about the popular meanings of male homelessness in Las Vegas, Nevada, in the late 1990s, and second, to consider the meanings that local homeless …


Canons By Consensus: Critical Trends And American Literature Anthologies, Joseph Thomas Csicsila Jan 1997

Canons By Consensus: Critical Trends And American Literature Anthologies, Joseph Thomas Csicsila

UNLV Retrospective Theses & Dissertations

Scholarly researchers have seldom recognized the college classroom textbook as a valid document of literary history, presumably because it is such an ordinary, taken-for-granted fixture in the academic environment. Canons by Consensus: Critical Trends and American Literature Anthologies, however, examines in detail the evolving critical reputations of thirty American authors in the twentieth century as reflected in these assigned anthologies. A study of nearly eighty college-level collections of American literature marketed between 1919 and 1998 shows that scholarly trends have significantly shaped their editors' perceptions of American writers over the last eighty years, indeed that the shifting paradigms within the …

The Impact Of A Substance Abuse Prevention Program: An Evaluation, Julie Ann Hogan

UNLV Retrospective Theses & Dissertations

This study tests the theory of risk and protective factors. The risk and protective theory suggests that substance abuse prevention programs, in order to be effective, must decrease risk factors and increase protective factors for youth. Seventeen risk and protective factors are identified in the literature and are tested in this study; To determine the degree to which this theory applies to prevention programming, this study evaluates the effectiveness of a substance abuse prevention program entitled the National Youth Sports Program (NYSP). NYSP is a nationally sponsored summer youth and academic program that includes a prevention education component. Three hundred …

Sivilizing' The Washoe Zephyr: Mark Twain's Writing For The "Buffalo Express", 1869-1871, Janice E Mcintire

UNLV Retrospective Theses & Dissertations

Mark Twain reprinted fifteen sketches from the Buffalo Express in his 1875 subscription volume entitled Sketches, New and Old, and eighteen were printed in the Galaxy around the time of their appearance in the Express. Since that time, "Journalism in Tennessee," "Capitoline Venus," "A Ghost Story," "A Curious Dream," and a few others have been anthologized, most recently in Louis J. Budd's Mark Twain: Collected Tales, Sketches, Speeches, & Essays (2 vols., 1991). However, except for their original newspaper printing, the signed sketches have yet to be published in their entirety as a volume. This study is a critical edition …

Technology Use By A College Of Education Faculty And Factors Influencing Integration Of Technology In An Undergraduate Teacher Preparation Program, Christy J Falba

UNLV Retrospective Theses & Dissertations

This study describes current levels of technology use by a College of Education (COE) faculty and use of technology in teaching classes. In addition, the formation of a systematic plan for integrating technology throughout the teacher preparation programs was explored. Both quantitative and qualitative methods were used in this two-phase study; Phase I survey results suggested that although 93% of faculty believed technology in teacher education was very important or somewhat important, use of technology in teaching was limited. Consistent with previous findings on university faculty use of technology, COE faculty rated themselves as having high levels of knowledge and …


Habitat Patch Dynamics Of Desert Bighorn Sheep Ovis Canadensis Nelsoni In The Eastern Mojave Desert, Darren Del Divine Jan 1997

Habitat Patch Dynamics Of Desert Bighorn Sheep Ovis Canadensis Nelsoni In The Eastern Mojave Desert, Darren Del Divine

UNLV Retrospective Theses & Dissertations

The individual chapters of this Dissertation were designed to examine desert bighorn habitat, and the disjunct nature of that habitat. The findings of the first chapter illustrated that although 30 m elevation data yielded a more accurate depiction of the landscape, 100 m data was still adequate for determining habitat quality. The second chapter illustrated that the traditional bighorn habitat model was inadequate when applied to four Eastern Mojave Desert mountain ranges because of its unrealistic distance to permanent water requirement. It was also determined that a single habitat definition could not be formulated that worked equally well on all …
