Application Of A Judgment Model Toward Measurement Of Clinical Judgment In Senior Nursing Students, Tiwaporn Pongmarutai

UNLV Theses, Dissertations, Professional Papers, and Capstones

Clinical judgment, defined as “the application of the nurse’s knowledge and experience in making decisions about client care” (The National Council of State Boards of Nursing, 2005, p. 2), has been recognized as a vital and essential skill for healthcare providers when caring for clients. Undisputedly, nurses represent the largest component of the healthcare profession and, therefore, play a major role in ensuring quality patient care in the United States. Although the concept of clinical judgment in nursing has been discussed for more than three decades, and in spite of numerous efforts to improve student clinical judgment, the recent literature …

Vertical Transmission Of West Nile Virus In Culex Spp. Mosquitoes Of Clark County, Nevada, Vivek K. Raman

UNLV Theses, Dissertations, Professional Papers, and Capstones

West Nile Virus (WNV) is an RNA arbovirus that cycles between mosquitoes and birds, but also infects and causes disease in humans, horses and other vertebrate species. Although most infections are asymptomatic, WNV has emerged as the most common cause of epidemic meningoencephalitis in North America and the leading cause of arboviral encephalitis in the United States.

Mosquitoes of the genus Culex are the most active vectors of WNV in North America. Approximately 85% of human WNV infections in the United States occur in late summer with a peak number of cases in August and September. Vertical transmission is defined …

Private Or Public Insurance? The Institutional History Of Health Care In The United States And The United Kingdom, Karin M. Abel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary question at issue in this paper is the following: given the similarities between the two countries with regard to welfare state institutions, why have the United States and the United Kingdom diverged on the issue of health care? Drawing on sociological institutionalism, a branch of the new institutionalist paradigm, this paper provides an answer to this question: during the formative years of the health care stories in the two countries, variations in institutional and cultural conditions produced contrasting policy outcomes. More specifically, this paper discusses how the combination of institutions (political, labor, and medical) and culture led to …

Parental Attitudes And Perceptions Related To Their Children's Physical Activity And Eating Patterns, Megan Leatham Dubois

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Children's physical inactivity and poor eating patterns have received a great deal of attention in our country and worldwide. Studies have been conducted to identify determinates related to children's physical activity and eating patterns and to identify strategies for promoting positive behaviors. Parental support is a well-accepted determinate of children's physical activity and eating patterns. However, little qualitative research has been done to determine parental attitudes and perceptions related to this critical role.

First, the study sought to gain a greater understanding of parental perspectives on their children's physical activity and eating patterns. Second, the study examined parental attitudes and …

Poisson Process Monitoring, Test And Comparison, Qing Chen

UNLV Theses, Dissertations, Professional Papers, and Capstones

The task of determining whether a sudden change occurred in the generative parameters of a time series generates application in many areas. In this thesis, we aim at monitoring the change-point of a Poisson process by method, which is characterized by a forward-backward testing algorithm and several overall error control mechanisms. With the application of this proposed method, we declare that Mount Etna is not a simple Poissonian volcano, because two different regimes divided by the change point, January 30th 1974, are identified. The validation procedures, used in a complementary fashion, by the formal hypothesis tests and graphical method will …

UNLV Theses, Dissertations, Professional Papers, and Capstones

As of 2008, the U.S. Department of Labor is predicting a need for greater than one million new registered nurses by the year 2016 (American Associations of Colleges of Nursing [AACN], 2008). One way that nursing schools around the country are dealing with this issue is through the creation of accelerated second-degree programs for non-nursing graduates.

The purpose of this descriptive study was to examine the perceptions of educational preparation of accelerated second-degree baccalaureate graduates, who have been out of school for at least one year, but no longer than four years. The sample consisted of 54 graduates from an …

Chemical And Electronic Structure Of Surfaces And Interfaces In Compound Semiconductors, Sujitra Pookpanratana

UNLV Theses, Dissertations, Professional Papers, and Capstones

The interface formation between two different materials is important in applications for optoelectronic devices. Often, the success or performance of these devices is dependent on the formation of these heterojunctions. In this work, the surface and interfaces in such materials for optoelectronic devices are investigated by a suite of X-ray analytical techniques including X-ray photoelectron (XPS), X-ray excited Auger electron (XAES), and X-ray emission (XES) spectroscopies to provide novel insight.

For the group III-nitrides (e.g., AlxGa1-xN) used in many light emitting devices, a significant challenge exists to form an Ohmic contact. The electron affinities and band gaps of GaN and …

Environmental Influence On Brain, Behavior, And Gene Expression In Drosophila, Xia Wang

UNLV Theses, Dissertations, Professional Papers, and Capstones

Brain development and behavior are sensitive to environmental stimuli. To gain an understanding of how and to what extent environmental variations, particularly with regard to thermal stress and sensory input, affect brain development, function, and genomic activity, in this dissertation, three interrelated studies were conducted in Drosophila melanogaster.

The first study examined the effects of ecologically-relevant hyperthermia stress on development of the Drosophila mushroom body (MB), a conserved sensory integration and associative center in the insect brain. A daily hyperthermic episode throughout larval and pupal development was shown to severely disrupt MB anatomy by reducing intrinsic Kenyon cell neuron …

Sequence And Chemostratigraphy Of The Middle Cambrian Succession In Nevada And Utah, Robyn A. Howley

UNLV Theses, Dissertations, Professional Papers, and Capstones

The House Range Embayment of western Utah and eastern Nevada was a prominent topographic feature on the passive margin of western North America during the middle and late Cambrian. In this study, detailed documentation of sequence boundaries, and their intervening sequences across a platform-to-basin transect of the House Range Embayment was used to establish a sequence-stratigraphic framework from which the depositional history of the embayment was deciphered. This framework was then used to test the hypothesis that the House Range Embayment formed by tectonic subsidence. In addition, the chemostratigraphic (δ13Ccarb) record across the embayment was analyzed within this framework to …

Taxing Matters: How The Us Tax Code Affects Gamblers, Todd Haushalter

UNLV Theses, Dissertations, Professional Papers, and Capstones

It has been said that the only sure things in life are death and taxes, and while this is most certainly true of the former, the later will require mastery of the tax code and ensuing cases before you will have a complete picture. The tax code, which started out as a 400 page document is now some 3,387 pages long with a voluminous amount of tax court cases to interpret the code, and many issuances by the Internal Revenue Service to provide further clarification of the code. Somewhere intertwined in the tax code and the ensuing court cases is …

Sunrise, Sunset? Comparing The Las Vegas And Macao Gaming Markets In 2010, Jung-Eun Joyce Kim

UNLV Theses, Dissertations, Professional Papers, and Capstones

When The Mirage opened in 1989, it was the most expensive hotel-casino in history with a construction cost of $630 million. Along with eruption of its signature attraction, The Volcano, this high profile project started a tourism boom and started a trend of further developments of integrated mega-resorts. The Mirage set a new level of experience for Las Vegas strip. However, the global financial crisis that started in 2007 has since left Las Vegas with the highest foreclosure rate in the country and sent accompanying businesses and growth tumbling (Veiga, 2010). Gaming industry has long been thought to be recession …

Data Routing In Multicore Processors Using Dimension Increment Method, Arpita H. Kadakia

UNLV Theses, Dissertations, Professional Papers, and Capstones

A Deadlock-free routing algorithm can be generated for arbitrary interconnection network using the concept of virtual channels but the virtual channels will lead to more complex algorithms and more demands of NOC resource.

In this thesis, we study a Torus topology for NOC application, design its structure and propose a routing algorithm exploiting the characteristics of NOC. We have chosen a typical 16 (4 by 4) routers Torus and propose the corresponding route algorithm. In our algorithm, all the channels are assigned 4 different dimensions (n0,n1,n2 & n3). By following the dimension increment method, we break the dependent route circles, …

The Interaction Of Rock And Water During Shock Decompression: A Hybrid Model For Fluidized Ejecta Formation, Audrey Hughes Rager

UNLV Theses, Dissertations, Professional Papers, and Capstones

Crater and ejecta morphology provide insight into the composition and structure of the target material. Martian rampart craters, with their unusual single-layered (SLE), double-layered (DLE), and multi-layered ejecta (MLE), are the subject of particular interest among planetary geologists because these morphologies are thought to result from the presence of water in the target. Also of interest are radial lines extending from the crater rim to the distal rampart of DLE craters. Exactly how these layered ejecta morphologies and radial lines form is not known, but they are generally thought to result from interaction of the ejecta with the atmosphere, subsurface …

Detention Basins For Phosphorus And Sediment Control In Clark County, Nevada, Amina Rashid Lodhi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Nonpoint source urban stormwater runoff degrades aquatic ecosystems, and causes flooding. To mitigate its effects on natural and human environments best management practices (BMPs) became popular strategies to protect the integrity of water quality. Similarly, to mitigate the effects of stormwater quantity, detention basins (DBs) were put into place as flood control structures. Water quality control remains an unexplored and important aspect of DB utility, particularly, in arid regions. Since DBs are depressions in the earth and retain water over the course of several hours to days after a rain event, they can potentially act as BMPs. A key pollutant …

Production, Purification And Crystallization Of Membrane Integrated Multimeric Bax, Adelbert Mark Villoso

UNLV Theses, Dissertations, Professional Papers, and Capstones

Apoptosis, or programmed cell death, is a vital process intimately involved in the embryonic development and homeostatic maintenance of all multicellular organisms. The committing step to apoptosis is regulated by a key protein, Bax, and its ability to integrate and form a pore structure at the outer mitochondrial membrane.

Unfortunately, the molecular details of apoptosis remain largely unclear due to the lack of structural data of integral membrane (IM) Bax. Experimental limitations of membrane protein production have slowed the pursuit of an IM-Bax structure simply because standard protocols for producing recombinant IM-Bax are inefficient in producing adequate quantities of IM-Bax …

History And Transnational Identities In Junot Díaz’S The Brief Wondrous Life Of Oscar Wao, Brian Joseph Flores

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of my thesis is to analyze Junot Díaz’s The Brief Wondrous Life of Oscar Wao and evaluate the role literature plays within the larger context of the relationship among the different countries and cultures in the Western Hemisphere, as well as the place historical events play within this understanding. In Díaz’s novel, there is an understanding of the presence of multiple cultural identities. This awareness of multiple cultural identities leads to the difficulty the characters encounter when trying understanding themselves as individuals. On a much larger scale, the characters also try to understand their cultural, social, and historical …

Dynamic Distributed Programming And Applications To Swap Edge Problem, Feven Z. Andemeskel

UNLV Theses, Dissertations, Professional Papers, and Capstones

Link failure is a common reason for disruption in communication networks. If communication between processes of a weighted distributed network is maintained by a spanning tree T, and if one edge e of T fails, communication can be restored by finding a new spanning tree, T’. If the network is 2-edge connected, T’ can always be constructed by replacing e by a single edge, e’, of the network. We refer to e’ as a swap edge of e.

The best swap edge problem is to find the best choice of e’, that is, that e which causes the new spanning …

Learning With Animation And The Illusion Of Understanding, Eugene Sam Paik

UNLV Theses, Dissertations, Professional Papers, and Capstones

A controlled experiment was conducted on the effects of two types of animation - motion and highlighting - on learning. The treatment consisted of a 3.5 minute multimedia presentation that described the workings of a flushing toilet tank. A 2x2 factorial design ({motion, no-motion} x {highlight, no-highlight}) was employed with two dependent measures of learning (retention and transfer). Participants consisted of 65 undergraduates. Highlighting animation had a positive effect on both retention and transfer while motion animation had a negative effect on transfer. No significant interaction was detected between motion and highlighting.

In addition, the experiment tested the illusion of …

Building Dupont: Capitalism, Manufactures, And Place In Early America, 1800-1820, Christopher Manning

UNLV Theses, Dissertations, Professional Papers, and Capstones

Though there is a rich literature dealing with the DuPont Company, the historiography remains dedicated to studies of the family’s life, corporate methods, working-class culture, and technological know-how. Rarely do studies engage the company’s wider economic position or regional influence in early America. This study analyzes the way early American culture guided and influenced DuPont’s growth and success. It also examines the company’s efforts to promote manufactures, create markets, and shape its surrounding landscape. As in other parts of the world, the development of industrial capitalism, and the wider acceptance of domestic manufacturers and large-scale industry in the United States …

Carbon Isotopic Fractionation Across A Late Cambrian Carbonate Platform: A Regional Response To The Spice Event As Recorded In The Great Basin, Jonathan Lloyd Baker

UNLV Theses, Dissertations, Professional Papers, and Capstones

Geochemical models have suggested that the late Cambrian was characterized by a greenhouse climate with high pCO2. Furthermore, stableisotope analyses within the Great Basin have documented a large carbonate isotope (δ13Ccarb) excursion, known as the Steptoean Positive Carbon Isotope Excursion (SPICE). This event has been documented globally, and is interpreted as having resulted from enhanced organic carbon burial. Unless the size of carbon reservoirs in the Cambrian ocean was significantly different from those of the Cenozoic, this forcing should have resulted in a comparable carbon-isotope excursion in organic matter (δ13Corg). It is also predicted that increased organic carbon burial would …

Self-Stabilizing Leader Election In Dynamic Networks, Hema Piniganti

UNLV Theses, Dissertations, Professional Papers, and Capstones

The leader election problem is one of the fundamental problems in distributed computing. It has applications in almost every domain. In dynamic networks, topology is expected to change frequently. An algorithm A is self-stabilizing if, starting from a completely arbitrary configuration, the network will eventually reach a legitimate configuration.

Note that any self-stabilizing algorithm for the leader election problem is also an algorithm for the dynamic leader election problem, since when the topology of the network changes, we can consider that the algorithm is starting over again from an arbitrary state. There are a number of such algorithms in the …
