Understanding Human Performance And Social Presence: An Analysis Of Vigilance And Social Facilitation, Victoria Claypoole
Electronic Theses and Dissertations
Social facilitation is characterized by improved performance on simple, or well-known, tasks and impaired performance on complex, or unfamiliar, tasks. Previous research has demonstrated that the use of social presence may improve performance on cognitive-based tasks that are relevant to many organizational contexts, such as vigilance. However, to date, there has not been consolidation of the research regarding the different implementations of social facilitation, or any analysis indicating which types of social presence are best under varying conditions. The present dissertation describes three experiments that seek to contribute to a taxonomic framework of social facilitation. Experiment One statistically established a …

Dynamically Tunable Plasmonic Structural Color, Daniel Franklin
Electronic Theses and Dissertations
Functional surfaces which can control light across the electromagnetic spectrum are highly desirable. With the aid of advanced modeling and fabrication techniques, researchers have demonstrated surfaces with near arbitrary tailoring of reflected/transmitted amplitude, phase and polarization - the applications for which are diverse as light itself. These systems often comprise of structured metals and dielectrics that, when combined, manifest resonances dependent on structural dimensions. This attribute provides a convenient and direct path to arbitrarily engineer the surface's optical characteristics across many electromagnetic regimes. But while many of these plasmonic systems struggle to compete with the efficiency of pre-existing technologies, the …

Pg-Vtv Biogenesis Requires Atp To Facilitate Phosphorylation Of Syntaxin 17, Anika Saxena
Electronic Theses and Dissertations
The uptake of cytotoxic free fatty acids (FFA) and their conversion to physiologically expedient triglycerides (TAG) which are later on assimilated to very low density lipoproteins (VLDL) is of utmost value among the multifarious tasks performed by the liver. Inflated concentration of VLDL in the blood stream directly correlates with the reinforcement of atherosclerosis. VLDL is synthesized in the hepatic endoplasmic reticulum (ER) and transported to the Golgi where it encounters several alterations. It is then enclosed in distinct post-Golgi VLDL transport vesicles (PG-VTVs) and released into the blood. The data generated in our lab has proved the requirement of …

Development Of A Functional In Vitro 3d Model Of The Peripheral Nerve, Wesley Anderson
Development Of A Functional In Vitro 3d Model Of The Peripheral Nerve, Wesley Anderson
Electronic Theses and Dissertations
Peripheral neuropathies, affect approximately 20 million people in the United States and are often a complication of conditions such as diabetes that can result in amputation of affected areas such as the feet and toes. In vitro methodologies to facilitate the understanding and treatment of these disorders often lack the cellular and functional complexity required to accurately model peripheral neuropathies. In particular, they are often 2-D and functional readouts, such as electrical activity, are limited to cell bodies thereby limiting the understanding of axonopathy which often characterizes these disorders. We have developed a functional 3-D model of peripheral nerves using …

Development And Characterization Of Solid-Contact Paper-Based And Micro Ion-Selective Electrodes For Environmental Analysis, Stephanie Armas
Electronic Theses and Dissertations
Ion-selective electrodes (ISEs) have extensively been used for food analysis, as medical diagnostic tools, and for some environmental applications. However, ISEs are hindered by the need of a bulky reference electrode and the pre-conditioning step of the sensor, which can often be lengthy. This work will discuss how the direct addition of target analyte into the cocktail sensing membrane can circumvent the pre-conditioning step. Furthermore, the work is presented in an optimized ready-to-use single strip design, where the bulky glass reference electrode (RE) is no longer needed. The bulky RE was replaced by drop casting a simple two-component mixture consisting …
