The Feasibility Of An Advanced Practice Registered Nurse-Managed Adhd Resource Center In Missouri, Kara Janelle Stackley

Dissertations

The primary objective of this project was to develop a survey to determine provider receptiveness to referring patients to an advanced practice registered nurse-(APRN) managed center for the diagnosis and management of Attention Deficit/Hyperactivity Disorder (ADHD). A secondary aim of this project was to develop a business plan for the center, provided feedback from the survey was determined to be supportive. Physicians were more likely to use ADHD clinical guidelines (65%) in their practice and expressed greater comfort managing ADHD. Only 50% of APRNs use the clinical practice guidelines and 50% reported they were uncomfortable diagnosing and managing ADHD. Almost …

Identification And Management Of Vertebral Column Fractures In Primary Care, Christopher Richard Hemmer

Dissertations

The purpose of this project is to perform a program evaluation of current treatment patterns of primary care providers for osteoporotic vertebral compression fractures (VCF). VCF’s result in significant morbidity and long term sequelae following a VCF is not uncommon. Additionally, there is controversy regarding the diagnosis and management of this disorder, especially as these relate to the clinical practice guidelines. This practice evaluation project included a pre and post-test survey and a continuing education offering. Thirty-nine physicians and nurse practitioners completed the survey instruments and attended the continuing education sessions. The educational session resulted in improvement of the provider’s …

Ultracold Neutron Depolarization In Magnetic Bottles, A. Steyerl, Charles Kaufman, Gerhard Müller, S. S. Malik, A. M. Desai

Physics Faculty Publications

We analyze the depolarization of ultracold neutrons confined in a magnetic field configuration similar to those used in existing or proposed magnetogravitational storage experiments aiming at a precise measurement of the neutron lifetime.We use an extension of the semiclassical Majorana approach as well as an approximate quantum mechanical analysis, both pioneered by Walstrom et al. [Nucl. Instrum. Methods Phys. Res. A 599, 82 (2009)]. In contrast with this previous work we do not restrict the analysis to purely vertical modes of neutron motion. The lateral motion is shown to cause the predominant depolarization loss in a magnetic storage trap. …

Semistochastic Projector Monte Carlo Method, F. R. Petruzielo, A. A. Holmes, Hitesh J. Changlani, M. P. Nightingale, C. J. Umrigar

Physics Faculty Publications

We introduce a semistochastic implementation of the power method to compute, for very large matrices, the dominant eigenvalue and expectation values involving the corresponding eigenvector. The method is semistochastic in that the matrix multiplication is partially implemented numerically exactly and partially stochastically with respect to expectation values only. Compared to a fully stochastic method, the semistochastic approach significantly reduces the computational time required to obtain the eigenvalue to a specified statistical uncertainty. This is demonstrated by the application of the semistochastic quantum Monte Carlo method to systems with a sign problem: the fermion Hubbard model and the carbon dimer.

Improving Phosphorus Use Efficiency Through Organically Bonded Phosphorus, Micheal W. Hill

Theses and Dissertations

Current maximum efficiency of phosphorus (P) fertilizers that is utilized by plants in the same year of application ranges from near zero to thirty percent. Despite low utilization of P in crop production, yields are often limited by P deficiencies. Innovative technology is requisite to achieve greater efficiency as fertilizer demands are increasing, while phosphorus mineral resources are rapidly being depleted. A growing environmental concern for nutrient pollution of surface waters also carries significant weight. A novel new product, Carbond® P, is promising technology to increase P use efficiency. Research is needed to understand its capabilities and the functioning mechanisms …

Modeling Radial Bernstein Modes In A Finite-Length Axisymmetric Non-Neutral Plasma, Mark Andrew Hutchison

Theses and Dissertations

Axisymmetric radial Bernstein modes are known to exist in non-neutral plasmas and have been studied theoretically and computationally in 1D, but detection of these modes has still proven to be difficult due to self-shielding. To help advance the work on this front we created a 2D particle-in-cell (PIC) code that simulates a non-neutral plasma in a Malmberg-Penning trap. A detailed description of the PIC code itself has been included that highlights the benefits of using an $r^2$--$z$ grid and how it can be tested. The focus of the PIC simulation was to discover how best to drive and detect these …

Feminism And The New Woman In The Gilbert & Sullivan Operas, Heather Dawn Zurcher

Theses and Dissertations

The operas by playwright W. S. Gilbert and composer Arthur Sullivan have been considered some of the most popular and successful pieces of musical theatre in the English language. While their joint creative output neared perfection, Gilbert and Sullivan's working relationship was fraught with conflict. The two men's opposing personalities led them to favor disparate styles and work towards different goals. However, the ability to balance contrasting tones, such as sarcasm and sympathy, resulted in their overwhelming success. I analyze this "winning formula" by looking at the influence of feminism, especially the "New Woman" literary movement, on the works of …

Monitoring Land-Cover Change In The Las Vegas Valley: A Study Of Five Change Detection Methods In An Urban Environment, Bonnie Diane Weidemann

Theses and Dissertations

Change detection is currently a topic of great interest to theoretic geographic researchers. The necessity to map, monitor, and model land cover change is also important to a variety of applied fields as varied as urban planning and military intelligence. This research compares five algorithms to map urban land cover change in the greater Las Vegas, Nevada metropolitan area. Landsat Thematic Mapper imagery acquired on May 1990 and May 2000 was used as the primary data. The change detection methods yielded simple maps of change vs. no change. These algorithms included image differencing, image ratioing, image regression, vegetation index differencing, …

Materialism And Psychological Well-Being: A Meta-Analytic Study, Kaylene Joy Fellows

Theses and Dissertations

The scholarly study of materialism is becoming more common in a variety of disciplines. This thesis provides an empirical review of this burgeoning body of literature by conducting a meta-analysis of the relationship between materialism and psychological well-being. A weighted overall effect size from 47 published and unpublished samples indicated that materialism was significantly related to lower psychological well-being. This effect size was modest in strength (r = .159). Materialism scale, psychological scale valance, age of sample, and publication status of the study did not moderate this relationship. Culture did moderate the relationship, with a stronger relationship in individualistic cultures …

A Survey Of Invasive Exotic Ants Found On Hawaiian Islands: Spatial Distributions And Patterns Of Association, Camie Frandsen Martin

Theses and Dissertations

An intensive sampling of all ant species encountered on 6 Hawaiian Islands: Big Island, Maui, Oahu, Kauai, Molokai, and Lanai took place between 1988 and 1996. Species presence and absence was recorded at each site. Using remote sensing, variables were added insitu and used throughout my analysis. Species accumulation curves suggest that sampling was comprehensive. There is a significant trend between island area and species richness which validates the Theory of Island Biogeography for invasive species. Islands were found to be significantly nested by area, order, and tourism. Cluster analysis shows a link between elevation, land-use and island, and species …

Vibrotactile Feedback Generation Using Envelope Waveforms And Eccentric-Mass Motors, Michael G. Plooster

Theses and Dissertations

The usefulness of vibrotactile feedback as a channel to communicate information has been widely recognized. However, most of the recent work on this subject uses actuators that are either too expensive or too large for many practical applications. This thesis explores the generation of vibrotacatile feedback patterns using a simple, inexpensive eccentric-mass motor that is constrained to use a constant voltage and a low on/off switching frequency. In particular, it explores the pulse timing method, which utilizes the slow transient response of the eccentric-mass motor to calculate pulse and rest times for an arbitrary envelope waveform shape. Several hardware tests …

Impact Of Margin Size On The Predicted Risk Of Radiogenic Second Cancers Following Proton Arc Therapy And Volumetric Modulated Arc Therapy For Prostate Cancer, Laura A. Rechner, Rebecca M. Howell, Rui Zhang, Wayne D. Newhauser

Faculty Publications

We previously determined that the predicted risk of radiogenic second cancer in the bladder and rectum after proton arc therapy (PAT) was less than or equal to that after volumetric modulated arc therapy (VMAT) with photons, but we did not consider the impact of margin size on that risk. The current study was thus conducted to evaluate margin size's effect on the predicted risks of second cancer for the two modalities and the relative risk between them. Seven treatment plans with margins ranging from 0 mm in all directions to 6 mm posteriorly and 8 mm in all other directions …

Lo Grotesco Y La Identidad Nacional En Huasipungo Y El Chulla Romero Y Flores De Jorge Icaza, Ernesto Raul Gonzalez

Theses and Dissertations

Este estudio busca analizar lo grotesco y su relación con la identidad nacional en las dos novelas más importantes de Jorge Icaza: Huasipungo (1934) y El Chulla Romero y Flores (1958). Estas obras exploran los temas de la animalización y la máscara social dentro del contexto de la sociedad ecuatoriana de la primera mitad del siglo XX para denunciar el abuso de los indígenas y el trauma del mestizo por tener sangre indígena. Estos dos conceptos se conectan con la noción de la construcción de una verdadera identidad nacional a través del indigenismo y el reconocimiento de la ascendencia nativa.

Recognition Of Compassion Fatigue Among Medical-Surgical Nurses: The Provision Of Education To Manage The Effects, Kandace Woodruff

Doctor of Nursing Practice (DNP) Projects

The Institute of Medicine (IOM) (2010) recommends that healthcare organizations make the “recruitment and retention of qualified nurses a priority”. The ability to comply with the recommendation is fraught with challenges. Nurses are required to care for patients across the age span with varying medical complexities. There are work related stressors which are inherent to the care of a more acutely ill patient population. The tenuousness produced by this type of environment can predispose the nurse to a stress induced phenomenon known as, Compassion Fatigue. The literature is abounding with information related to compassion fatigue among various nursing specialties. However, …

Vat Fraud & Triangulation, Richard Thompson Ainsworth

Faculty Scholarship

Missing trader intra-community (MTIC) fraud has received a lot of domestic enforcement attention. True cross border enforcement (joint or coordinated multi-Member State audit) has been limited. There are signs that this is changing as the Member States become more aggressive in their search for revenue.

Along with this shift in enforcement focus, triangulation analysis has moved from being an interesting aspect of the MTIC fraud structure to the central element in a larger understanding of how a fraudster thinks and how he carries out his fraud. We are coming to understand that triangulations are not only the mechanism of how …

Liquid-Liquid Equilibrium Of Biodiesel Components, Joseph C. Bell

Theses and Dissertations

Biodiesel is produced from vegetable oils through transesterification. Triglyceride mixtures extracted from oilseed feedstocks are upgraded by reaction with an alcohol in the presence of a catalyst to produce fatty acid esters. This reaction produces a mixture of esters, glycerin, alcohol, and catalyst. Separation of the fatty acid esters (biodiesel) and glycerin can be accomplished through liquid-liquid extraction by water addition. Designing liquid-liquid extraction with water as the solvent requires ternary liquid-liquid equilibrium data for mixtures of water, glycerin, and fatty acid esters. Ternary mixture LLE data have been experimentally measured for several of these systems. Those measured include mixtures …

Best Practices Using Building Information Modeling In Commercial Construction, Simon Beveridge

Theses and Dissertations

There has been an increase in adoption of building information modeling (BIM) by commercial contractors over the past few years but there is not a clear indication of current application or the frequency of each use. This research was undertaken to determine the frequency and best practices of using BIM in commercial construction. Leading commercial contracting firms were contacted and employees were selected to complete a telephone survey that was designed to determine how they are using BIM. It was found that BIM is being used with more frequency on projects, with plans to continue to implement it even further …

Advanced Numerical Methods In General Relativistic Magnetohydrodynamics, Michael J. Besselman

Theses and Dissertations

We show our work to refine the process of evolutions in general relativistic magnetohydrodynamics. We investigate several areas in order to improve the overall accuracy of our results. We test several versions of conversion methodologies between different sets of variables. We compare both single equation and two equations solvers to do the conversion. We find no significant improvement for multiple equation conversion solvers when compared to single equation solvers. We also investigate the construction of initial data and the conversion of coordinate systems between initial data code and evolution code. In addition to the conversion work, we have improved some …

Efficient Estimation For Small Multi-Rotor Air Vehicles Operating In Unknown, Indoor Environments, John Charles Macdonald

Theses and Dissertations

In this dissertation we present advances in developing an autonomous air vehicle capable of navigating through unknown, indoor environments. The problem imposes stringent limits on the computational power available onboard the vehicle, but the environment necessitates using 3D sensors such as stereo or RGB-D cameras whose data requires significant processing. We address the problem by proposing and developing key elements of a relative navigation scheme that moves as many processing tasks as possible out of the time-critical functions needed to maintain flight. We present in Chapter 2 analysis and results for an improved multirotor helicopter state estimator. The filter generates …

Website Adaptive Navigation Effects On User Experiences, James C. Speirs

Theses and Dissertations

The information search process within a website can often be frustrating and confusing for website visitors. Navigational structures are often complex and multitiered, hiding links with several layers of navigation that user's might be interested in. Poor navigation causes user frustration. Adaptive navigation can be used to improve the user's navigational experience by flattening the navigational structure and reducing the number of accessible links to only those that the user would be interested in. This examines the effects on a user's navigational experience, of using adaptive navigation as the main navigational structure on a website. This study measured these effects …
