Volunteer Functions, Satisfaction, Commitment, And Intention To Leave Government Volunteering, Gisela R. Salas

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Traditionally, volunteerism has been deeply embedded in United States history with citizens showing a high level of social participation. In the United States there are 60.8 million volunteers, however, the supply of volunteer labor has been insufficient to meet the demands of organizations with recent reports showing a decrease. Trends as far back as the 1980s indicated that budgetary constraints coupled with increasing demands makes volunteering the logical alternative to sustain service delivery.

Many community, civic, and governmental organizations need and use volunteers to accomplish their missions. One of the greatest challenges, however, is ensuring that the volunteers remain satisfied …

"As-Yet-Still-Forgiven Past": Dylan Thomas And Nostalgia, David Bradley Bailey

College of Graduate Studies: Theses & Dissertations

Dylan Thomas exhibited a variety of nostalgic influences within his poetry. A careful study of his life will reveal a nostalgia that evolved from adolescent musings upon an ideal past, to a self-destructive urge to return to innocence through death. Thomas incorporates a variety of historical influences within this nostalgia, but his primary influence is ultimately his own tormented past. This study not only focuses on the personal nostalgia of one man, but the variety of ways nostalgia can affect people, history and society as sociological force.

Unsupervised Indexing Of Medline Articles Through Graph-Based Ranking, Jorge R. Herskovic

Dissertations and Theses (Open Access)

The biomedical literature is extensively catalogued and indexed in MEDLINE. MEDLINE indexing is done by trained human indexers, who identify the most important concepts in each article, and is expensive and inconsistent. Automating the indexing task is difficult: the National Library of Medicine produces the Medical Text Indexer (MTI), which suggests potential indexing terms to the indexers. MTI’s output is not good enough to work unattended. In my thesis, I propose a different way to approach the indexing task called MEDRank. MEDRank creates graphs representing the concepts in biomedical articles and their relationships within the text, and applies graph-based ranking …

Highly spin-polarized diluted ferromagnetic semiconductors are expected to be widely used as ideal spin injectors. Here, extensive first-principles density-functional theory calculations have been performed to investigate the feasibility of using Cr- and Mn-doped wurtzite polar AlN/GaN(0001) heterostructures, with the aim to realize the appealing half-metallic character and, hence, efficient electrical spin injection. To overcome the formation of detrimental embedded clusters, we propose digital delta-layer doping perpendicular to the growth direction so as to realize enhanced performance at room temperature. The formation energy, electronic and magnetic properties, and the degree of spin polarization for both neutral and charged valence states for …

Interference Effects Due To Projectile Target Nucleus Scattering In Single Ionization Of H₂ By 75-Kev Proton Impact, Jason S. Alexander, Aaron C. Laforge, Ahmad Hasan, Z. S. Machavariani, M. F. Ciappina, R. D. Rivarola, Don H. Madison, Michael Schulz

Physics Faculty Research & Creative Works

Doubly differential cross sections (DDCSs) for single ionization of molecular hydrogen by 75-keV proton impact have been measured and calculated as a function of the projectile scattering angle and energy loss. Interference structures are observed in the scattering angular dependence of the DDCSs, which disappear, however, at electron speeds near the projectile speed. The comparison to our calculations shows that the projectile-target nucleus interaction plays a central role. Furthermore, our data suggest that for a given scattering angle, ionization favors well-defined molecular orientations.

Modeling Physical-Chemical Properties Of High Dilutions: An Electrical Conductivity Study, Carla Holandino, Rafael Harduim, Venício Da Veiga, Sheila Garcia, Carlos Zacharias

Indian Journal of Research in Homoeopathy

The most common way to perform succussions is to place a liquid preparation inside a glass vessel and beat it vigorously against a hard elastic surface, either manually or using a mechanical apparatus. This procedure has been assumed able to transfer mechanical energy to the molecular level, where it becomes available to perform chemical work. Such interpretation has been enforced by observed changes in the electrical conductivity (EC) of High Dilutions (HD) due to succussion. In order to address this question, we compared the electrical conductivity changes of HD prepared from Vincristine sulfate (VCR) samples with those of an inert …

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The Hydro-NEXRAD merging algorithms include two options: (1) data-based merging; and (2) product-based merging. Data-based merging algorithm takes volume scan reflectivity data from all radars involved through preprocessing algorithm that performs volume data quality control, interpolates data to synchronize temporal scale between individual radars, and finally combines data onto a common geographic grid. Reflectivity values for a given location are assigned by a weighting function with respect to the distance from the radar. This single reflectivity field is then converted to rainfall amounts using a user-requested standard approach. In product-based merging algorithm reflectivity data from multiple radars are all converted …
