The Lived Experiences Of Acute-Care Bedside Registered Nurses Caring For Patients And Their Families With Limited English Proficiency, Jami-Sue Coleman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Approximately 8.6% of the total U.S. population is considered limited English proficient (LEP), a term that has been used by official US federal policy and will be used throughout this study. In a landmark report, the Institute of Medicine found that minorities received lower-quality health care than Caucasians even when insurance status, income, and other factors were equivalent. These differences were tied to issues such as bias, stereotypes and communication barriers between patients and their caregivers. In the hospital setting, registered nurses provide the most direct contact with patients and their families. Effective communication between patients and health care professionals …

Examining The Relationships Between Internalizing And Externalizing Problems And Academic Achievement, Lara Elizabeth Conrad

UNLV Theses, Dissertations, Professional Papers, and Capstones

The relationship between internalizing and externalizing problems and academic achievement for children and adolescents has been inconclusive. Particularly the relationship between the Behavior Assessment System for Children, Second Edition (BASC-2) reports of internalizing and externalizing problems and academic performance on the Woodcock-Johnson, Tests of Achievement, Third Edition (WJ-III:ACH). The current study examined the self and parent reports of internalizing and externalizing problems as measured by the BASC-2 and the relationship with academic skills as measured by the WJ-III:ACH. The referral source (private practice or school setting) was evaluated for severity of presenting internalizing and externalizing symptoms. Secondary data analysis was …

Investigating Potential Factors That Influence Recruitment For Parenting Skills Classes, Rachel Elizabeth Davis

UNLV Theses, Dissertations, Professional Papers, and Capstones

Juvenile delinquency and child maltreatment are prevalent in the U.S., particularly among ethnic minority children. Although parent skills training is effective in preventing these problems, recruitment and retention rates of parents from ethnic, racial, and socioeconomic minority groups are less than satisfactory. In a qualitative study of 13 high-risk African American mothers, Davis (2009) investigated the deterrents to recruitment and participation for parent skills training programs. The resulting theory, the Mothers Shouldn't Need Help Script, explicates the relationship between the beliefs reported by these mothers and participation in parenting skills classes. To build on these findings, the overarching purpose of …

The International Monetary Fund, Power Politics, And The Changing Political Economy Of The Twenty First Century, Eduardo Flores

UNLV Theses, Dissertations, Professional Papers, and Capstones

The governance of the global economy is in a constant state of change. Since the creation of the Bretton Woods system, the International Monetary Fund has had to pursue a series of reforms to meet the changing demands of the international monetary system. At times, the Fund's institutional design has been adjusted to reflect the rise and decline in economic fortunes of member states. Other times the Fund has been resistant to change. However, the original design has proved to be durable and has overcome a number of historical challenges. Currently, two realities are challenging the institutional design of the …

Design And Fabrication Of An Infrared Optical Pyrometer Asic As A Diagnostic For Shock Physics Experiments, Jared Gordon

UNLV Theses, Dissertations, Professional Papers, and Capstones

Optical pyrometry is the sensing of thermal radiation emitted from an object using a photoconductive device to convert photons into electrons, and is an important diagnostic tool in shock physics experiments. Data obtained from an optical pyrometer can be used to generate a blackbody curve of the material prior to and after being shocked by a high speed projectile. The sensing element consists of an InGaAs photodiode array, biasing circuitry, and multiple transimpedance amplifiers to boost the weak photocurrent from the noisy dark current into a signal that can eventually be digitized. Once the circuit elements have been defined, more …

Precipitation in the Intermountain West is characterized by its great variability in both spatial and temporal distributions. Moreover, the spatiotemporal distribution of the precipitation is changing due to the climate changes. In this dissertation, three studies are conducted to investigate the multi-scale temporal variability of precipitation, the performance of current climate models on this variability, the influence of large-scale ocean oscillations on heavy precipitation, and the impact of human induced global warming on storm properties.

The first study is to examine the performance of current climate models on the simulation of the multi-scale temporal variability determined from the observed station …

Examining The Inner Experience Of Four Individuals With Bipolar Disorder Using Descriptive Experience Sampling, Johanah Kang

UNLV Theses, Dissertations, Professional Papers, and Capstones

Bipolar disorder is a lifelong mood disorder with diagnostic criteria that provide a description of expected experiences of individuals diagnosed with BD (e.g., elevated mood, sadness, difficulty concentrating). Despite these criteria, the inner experience of these individuals is largely unknown. Understanding the inner experience of individuals diagnosed with BD may prove essential in understanding and treating BD. The present study examined the inner experience of four individuals diagnosed with BD using the Descriptive Experience Sampling (DES) method (Hurlburt 1990, 1993, 2011). Results revealed all our participants had clear and prevalent experiences of sensory awareness. They also had difficulties apprehending and …

Comparative Direct Democracy: A Study Of Institutions And Individuals, Donald D. Mirjanian

UNLV Theses, Dissertations, Professional Papers, and Capstones

Do institutions matter? This dissertation examines the role of institutions in the context of comparative direct democracy. Through an institutionalist framework, this study considers how the context in which the mechanism of direct democracy is first introduced has an impact on later usage, and how individuals operate when constrained by those very institutions. In particular, I examine the cases of Italy, France, Uruguay, and Venezuela and find that the inclusion of direct democracy mechanisms (most commonly, the referendum device) is more likely to occur when previously excluded "out-groups" participate in constitutional formation. In addition, I find that institutional design is …

The Effects Of The Jccs Curriculum On Juveniles' Legal Knowledge, Competency, And Anxiety, Leslie Strasser Murdock

UNLV Theses, Dissertations, Professional Papers, and Capstones

Current law requires that juveniles be competent to stand trial prior to their involvement as defendants in court. According to Dusky v. US, a defendant must have a rational and factual understanding of the court proceedings to be deemed competent to stand trial. Past studies call into question whether juveniles at any age could meet the understanding element of the standard articulated in Dusky v. US (1960). Additionally, youth with disabilities have less knowledge than their typical peers. Besides a lack of legal knowledge, court related anxiety has also been found to have a significant effect on youths going to …

Estimation Of Travel Time Based On Vehicle-Tracking Models, Anuj Nayyar

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this thesis we study the travel time problem based on the known traffic density model. Using the conservation law, we model the travel time function by a boundary value problem of a non homogeneous linear hyperbolic equation. The equation is transformed into an initial value hyperbolic equation, and the well-posedness of the problem is discussed. The mathematical analysis for both density and travel problems are given. We also derive the analytic solutions for several special cases of traffic density. Numerical schemes are proposed for solving for travel time problem. Several numerical examples are presented and error analysis on the …

Elements Of Traditional Folk Music And Serialism In The Piano Music Of Cornel Țăranu, Cristina Vlad

Glenn Korff School of Music: Dissertations, Theses, Student Creative Work, and Performances

The socio-political environment in the aftermath of World War II has greatly influenced Romanian music. During the Communist era, the government imposed regulations on musical composition dictating that music should be accessible to all members of society. Composers were therefore barred from writing works that were considered too complex or avant-garde for the standards of the nation. Many composers struggled with this official ideology because they wished to follow their own natural styles and desired to synchronize with Western compositional trends of the time, including aleatoric and twelve-tone serial music. Even before the government relaxed the restrictions on composition at …

Direct Observations Of Plasma Upflows And Condensation In A Catastrophically Cooling Solar Transition Region Loop, Norton B. Orange, David L. Chesney, Hakeem M. Oluseyi, Katie Hesterly, M Patel, Patrick Champey

Aerospace, Physics, and Space Science Faculty Publications

Minimal observational evidence exists for fast transition region (TR) upflows in the presence of cool loops. Observations of such occurrences challenge notions of standard solar atmospheric heating models as well as their description of bright TR emission. Using the EUV Imaging Spectrometer on boardHinode, we observe fast upflows (vλ −10 km s−1) over multiple TR temperatures (5.8 logT 6.0) at the footpoint sites of a cool loop (logT 6.0). Prior to cool loop energizing, asymmetric flows of + 5 km s−1 and −60 km s−1 are observed at footpoint sites. These flows, speeds, and patterns occur simultaneously with both magnetic …

Little Rituals, Bruce Johnson

UNLV Theses, Dissertations, Professional Papers, and Capstones

The following stories represent what I have accomplished in my three-and-a-half years in the Master of Fine Arts-Fiction program at University of Nevada, Las Vegas. They are all realist stories, most of them with a minimalist leaning. Together for the first time, they are more than a mere sum of the writing I've done in my time in the MFA program. They are the stories that, when I read them now, still occasionally delight me. Most of the stories that I wrote as an MFA candidate do not pass this test, and thus are not included here. If there is …

On High-Performance Parallel Fixed-Point Decimal Multiplier Designs, Ming Zhu

UNLV Theses, Dissertations, Professional Papers, and Capstones

High-performance, area-efficient hardware implementation of decimal multiplication is preferred to slow software simulations in a number of key scientific and financial application areas, where errors caused by converting decimal numbers into their approximate binary representations are not acceptable.

Multi-digit parallel decimal multipliers involve two major stages: (i) the partial product generation (PPG) stage, where decimal partial products are determined by selecting the right versions of the pre-computed multiples of the multiplicand, followed by (ii) the partial product accumulation (PPA) stage, where all the partial products are shifted and then added together to obtain the final multiplication product. In this thesis, …

Media Bias Through Facial Expressions On Local Las Vegas Television News Programs: A Visual Content Analysis, Jessica Zimmerman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Trust in news media has been considered an important base for social order and cohesion in society and is a crucial variable for evaluating news media. Media credibility has been questioned by the audience for some time and the audience's trust in the media has been slowly diminishing over the years. When a news broadcaster communicates a story on local television news, it is possible for his own opinions to leak through nonverbal communication, specifically facial expressions. This thesis explores the six local Las Vegas television news stations' anchors and reporters to visually analyze whether facial characteristics reveal media bias …

Pennsylvanian To Cretaceous Folds And Thrusts In South-Central Nevada: Evidence From The Timpahute Range, Angela Giovanna Russo

UNLV Theses, Dissertations, Professional Papers, and Capstones

Understanding Permian and Mesozoic contractional structures from southern California to northern Nevada requires correlation through south-central Nevada. After the Devonian-Mississippian Antler orogeny through the Permian-Triassic Sonoma orogeny and then up to the Sevier orogeny, south-central Nevada was thought to have remained tectonically inactive. However, Pennsylvanian through Jurassic age deformation is documented to the south in Death Valley and to the north. Identifying geometries, spatial relationships, and relative timing of deformations in the Timpahute Range, south-central Nevada, is an essential piece to completing the overall understanding of Nevada geology. The purpose of this study is to identify and analyze deformational structures …

Mechanisms For Regulation Of Plant Kinesins, Anindya Ganguly, Ram Dixit

Biology Faculty Research

Throughout the eukaryotic world, kinesins serve as molecular motors for the directional transport of cellular cargo along microtubule tracks. Plants contain a large number of kinesins that have conserved as well as specialized functions. These functions depend on mechanisms that regulate when, where and what kinesins transport. In this review, we highlight recent studies that have revealed conserved modes of regulation between plant kinesins and their non-photosynthetic counterparts. These findings lay the groundwork for understanding how plant kinesins are differentially engaged in various cellular processes that underlie plant growth and development.

Phenotypic Correlates Of The Lianescent Growth Form: A Review, Tomasz P. Wyka, Jacek Oleksyn, Piotr Karolewski, Stefan A. Schnitzer

Biological Sciences Faculty Research and Publications

Background

As proposed by Darwin, climbers have been assumed to allocate a smaller fraction of biomass to support organs in comparison with self-supporting plants. They have also been hypothesized to possess a set of traits associated with fast growth, resource uptake and high productivity.

Scope

In this review, these hypotheses are evaluated by assembling and synthesizing published and unpublished data sets from across the globe concerning resource allocation, growth rates and traits of leaves, stems and roots of climbers and self-supporting species.

Conclusions

The majority of studies offer little support for the smaller allocation of biomass to stems or greater …

Classroom Management Strategies: The Impact On Student Achievement, Hope Sowell

Doctoral Dissertations and Projects

The purpose of this causal comparative study was to test the theoretical Classroom Management Teacher Behavior Continuum of Wolfgang and Glickman (1980) that suggests that interventionist, noninterventionist, and interactionalist classrooms may differ in student outcomes. This study explored whether student outcomes in statewide standardized tests reading, English language arts, and math differ by interventionist, noninterventionist, or interactionalist teacher instruction management (IM) and behavior management (BM) styles. Survey data from eighty-three 3rd, 4th, and 5th grade teachers regarding instructional and behavioral classroom management beliefs were contrasted in the percentage students passing standardized tests of reading, ELA, and math using MANOVA at …

Mathematics Interventions: A Correlational Study Of The Relationship Between Level Of Implementation Of The Accelerated Math Program And Student Achievement, Deborah Walker Driesel

Doctoral Dissertations and Projects

Current legislation, such as No Child Left Behind (2001) or the Individuals with Disabilities Education Act (2004), has increased accountability for schools for the education of all students. These laws require schools to provide interventions for struggling learners, as part of the Response to Intervention process (IDEA, 2004). Accelerated Math (AM), published by Renaissance Learning, is a scientifically based program designed to supplement quality instruction as part of the RtI process. This correlational study examined ex post facto data using pre and posttest scores on the STAR Math Test in relation to amount of classroom time dedicated to AM instruction …

Discipleship In Education: A Plan For Creating True Followers Of Christ In Christian Schools, Joseph Allotta

Doctoral Dissertations and Projects

Students are often tested to evaluate their academic knowledge, but few Christian schools evaluate whether a student has become a true disciple of Christ. Schools need to know what they can do that actually has an impact. This project will focus on high school seniors at Baptist schools in the Tampa Area. Students will take a custom survey to determine their biblical knowledge, use of spiritual disciplines, and beliefs on morality, along with what factors influenced them the most. School officials will be interviewed to identify how each is attempting to influence said aspects. Special attention will be given to …

The Impact Of Interstate Highways On Land Use Conversion, Chris Mothorpe, Andrew R. Hanson, Kurt Schnier

Economics Faculty Research and Publications

Between 1945 and 2007, the United States lost 19.3 % of its agricultural land. Over the same time period, the construction of the 42,500 mile interstate highway system lowered transportation costs and opened large tracts of land for development. This paper assesses the impact of the interstate highway system on agricultural land loss in Georgia and uses the empirical estimates to simulate agricultural land loss resulting from the construction of additional interstate highways. Using a historical data set of agricultural land and interstate highway mileage, empirical estimates indicate that each additional mile of interstate highway reduces agricultural land by 468 …
