The Role Of Ontology In Information Management, Renato De Freitas Marteleto
UNLV Retrospective Theses & Dissertations
The question posed in this thesis is how the use of ontologies by information systems affects their development and their performance. Several aspects about ontologies are presented, namely design and implementation issues, representational languages, and tools for ontology manipulation. The effects of the combination of ontologies and information systems are then investigated. An ontology-based tool to identify email message features is presented, and its implementation and execution details are discussed. The use of ontologies by information systems provides a better understanding about their requirements, reduces their development time, and supports knowledge management during execution time.
Political Silence, The Feminine Style, And Aids: The Role Of Surrogate Speakers At The 1992 Presidential Nominating Conventions, Rebecca Ruth Moldenhauer
Political Silence, The Feminine Style, And Aids: The Role Of Surrogate Speakers At The 1992 Presidential Nominating Conventions, Rebecca Ruth Moldenhauer
UNLV Retrospective Theses & Dissertations
By the 1992 presidential campaign, AIDS had become a national health crisis and a highly publicized political issue that each party knew had to be addressed. Until this point, presidential candidates had remained relatively silent on the issue without consequence. Due to the nature of the subjects relating to AIDS (i.e. sex, homosexuality, drug use, etc.), the candidates, Bill Clinton and George Bush, felt it an unwise political decision to openly discuss it. Surrogate speakers, therefore, were chosen to address the AIDS issue at the 1992 national nominating conventions. Bob Hattoy, Elizabeth Glaser, and Mary Fisher delivered speeches about AIDS …

The Sweet River: A Collection Of Short Stories, Keith Harold Menter
The Sweet River: A Collection Of Short Stories, Keith Harold Menter
UNLV Retrospective Theses & Dissertations
Herein is a book-length collection of short stories entitled The Sweet River. The stories in this collection follow a self-discovered structural paradigm found in the works of influential short story writers. This paradigm comprises four sequential stages: situation, tension through a series of patient complications, catharsis or reversal and double reversal, and epiphany. Thematically, the stories feature a protagonist adrift from conformist society, in search of transcendence amid the age-old dichotomy between the self and the other, and ultimately facing a moral crucible. Stylistically, the stories rely heavily on the external landscape as a means of avoiding sentimentality while still …

UNLV Retrospective Theses & Dissertations
Metamorphic fabric measurements indicate only one deformational fabric (NNE) is present in the Ivanpah Mountains, indicating that the area experienced one orogenic event during the Early Proterozoic. Peak P-T conditions, using garnet-Al2SiO5-silica-plagioclase barometry and garnet-biotite thermometry, were ∼4.0kb and >700°C, respectively. Peak metamorphic-T's were recorded by the largest garnet studied; Electron Microprobe Analysis on monazite, using U-Th-Pb radioactive decay, suggest metamorphism occurred between 1752 +/- 86 Ma and 1689 +/- 34 Ma, similar to the age of the Yavapai terrane (∼1.70--1.69 Ma). These ages are constrained from six monazite grains included in three large garnets (2250--5000um). Matrix monazite from granitic …
Ridgelets: A Promising New Wavelet-Like Transform To Represent Objects With Linear Singularities, Maria Beatriz Teruel
Ridgelets: A Promising New Wavelet-Like Transform To Represent Objects With Linear Singularities, Maria Beatriz Teruel
UNLV Retrospective Theses & Dissertations
In the last two decades plenty of research has been carried out in the field of Wavelet theory and it is well known that wavelets can efficiently deal with point-like singularities. Unfortunately, such is not the case for higher dimensions singularities. To overcome this weakness of the Wavelet transform E. Candes and D. Donoho [4] introduced a new wavelet-like transform that can effectively deal with linear singularities in two dimensions, namely the Ridgelet transform. This new representation tool exploits the ability of wavelets to deal with point singularities. In fact, the Ridgelet transform is equivalent to a one-dimensional wavelet transform …
