A Methodology To Develop A Communication Protocol For Visualizing Simulations In A Collaborative Virtual Reality Environment, Lacey Suzanne Duckworth

Dissertations

In the technology field, simulations and collaborative virtual reality environments (CVREs) are not generally combined because it is complicated to develop large scale simulations within CVREs. The complexity of combining these two technologies in order to form a better form of visualization stems from the lack of a methodology to help derive these scalable simulations. Simulations require very complex calculations that the CVRE cannot perform as it is overloaded in calculations for the maintenance and stability of the environment itself. Since the simulation cannot be held within the CVRE, the solution is to move the simulation external to the CVRE …

Ruthenium-Based Olefin Metathesis Catalysts Bearing Ph-Responsive Ligands: External Control Of Catalyst Solubility And Activity, Shawna Lynn Balof

Compassionate Care, The Patient Perspective, Lori Burnell Phd

Dissertations

Professional mandates call for nurses to respond with compassion (e.g., American Nurses Association [ANA] Code of Ethics, International Council of Nurses [ICN]) and countless hospital mission and vision statements prominently display compassion as their fundamental purpose. As a component of healthcare and nursing models, however, defining characteristics and standards are inconsistent. Compassion as a means of establishing a connection on a spiritual level abounds in the literature (Buck, 2006; Grant, 2004; O'Brien, 2008; Schultz et al., 2007) and is documented as a nursing requirement (e.g., ANA, ICN); however, it remains virtually uncharted from the lens of the patient. Through interpretive …

Missouri Charter Schools And Educational Reform, Phillip James Guy

Dissertations

In 1998, Missouri‟s two largest school districts, St. Louis and Kansas City, had become, in the eyes of many, completely dysfunctional. In court-ordered attempts to end desegregation and improve academically, each district built costly and extravagant magnet schools; however, low test scores and high dropout rates continued. These problems, and others, would cause both districts to lose their state accreditations in the next ten years. In an effort to put the focus back on student learning and force these districts to improve, Missouri lawmakers passed Senate Bill 781. This bill allowed charter schools to open and operate within the Kansas …

Mixing Of Nanosize Particles By Magnetically Assisted Impaction Techniques, James V. Scicolone

Dissertations

Nanoparticles and nanocomposites offer unique properties that arise from their small size, large surface area, and the interactions of phases at their interfaces, and are attractive for their potential to improve performance of drugs, biomaterials, catalysts and other highvalue- added materials. However, a major problem in utilizing nanoparticles is that they often lose their high surface area due to grain growth. Creating nanostructured composites where two or more nanosized constituents are intimately mixed can prevent this loss in surface area, but in order to obtain homogeneous mixing, de-agglomeration of the individual nanoparticle constituents is necessary.

Due to high surface area, …
