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 …

Ridgelets: A Promising New Wavelet-Like Transform To Represent Objects With Linear Singularities, Maria Beatriz Teruel Jan 2003

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 …

The Relationship Between Restaurant Attribute Satisfaction And Return Intent In Theme Restaurants, Rachel Dawn Weiss Jan 2003

The Relationship Between Restaurant Attribute Satisfaction And Return Intent In Theme Restaurants, Rachel Dawn Weiss

UNLV Retrospective Theses & Dissertations

Theme restaurants were designed to provide their customers with a meal coupled with an entertaining experience (Bagli, 1998). After a rapid rise in popularity in the early to mid 1990's, theme restaurants began to experience a decline in market share. As the theme restaurant segment experiences the downsizing of many once popular brands, it is imperative that the industry segment investigate customer satisfaction with restaurant attributes in order to assess which areas are in need of improvement. Although much research has been conducted on customer satisfaction in the service industries, none has focused on the theme restaurant industry in particular. …

Creating Community Through Symbolic Discourse: An Analysis Of Jesse Jackson's Rhetoric At The Democratic National Conventions, 1984--2000, Lance Michael Young

UNLV Retrospective Theses & Dissertations

The Reverend Jesse Louis Jackson has addressed the Democratic National Convention through five consecutive election cycles. Jackson's political involvement works to challenge the majority value system. Each address aims to create a community consisting of minority voices in America by bringing them into the Democratic Party in hopes of changing national policy. Metaphorical strategy is used to symbolically create a community consisting of minority voices, the Democratic Party, and Jackson himself as the prophetic leader. Symbolically unifying the community against a common enemy strengthens Jackson's community.

A Study Of The Effects Of Lithium Perchlorate On Poly(Ethylene Oxide), (Peo) Melt Dynamic Behavior Using Fabry-Perot Interferometry, Radoslav Boykov Bogoslovov

UNLV Retrospective Theses & Dissertations

Poly(ethylene oxide)/lithium perchlorate (PEO/LiClO4) complexes are widely studied as a prototype solid polymer electrolyte in rechargeable lithium-polymer batteries. Characterizing the structure and dynamics of the system in its molten state is important for understanding the role of the polymer environment in lithium ion transport and conductivity. We implement a fiber-optic coupled Fabry-Perot interferometer to investigate the electrolyte elastic properties and structural response times, which are both related to the intrachain local mobility and therefore to ion diffusion. We propose a simple and inexpensive fiber-optic experimental design combining two experimental techniques, Fabry-Perot interferometry and photon correlation spectroscopy. Our tests and evaluation …

Investigation Of Phosphines As Potential Host Materials In Blue Dye-Doped Organic Light Emitting Devices, Murukkuwadura Aruni Desilva Jan 2003

Investigation Of Phosphines As Potential Host Materials In Blue Dye-Doped Organic Light Emitting Devices, Murukkuwadura Aruni Desilva

UNLV Retrospective Theses & Dissertations

Currently, the most efficient organic light emitting devices (OLEDs) are based on dye-doped OLEDs. The major obstacle has been developing a host material for blue OLEDs that has sufficiently high energy of emission (<380nm) to facilitate energy transfer to the dye. Previous studies of bis(diphenylphosphino)-E-Stilbene (P-STIL) suggested that tertiary aromatic diphosphines (TAPs) may be suitable candidates. Therefore, the P-containing materials, 4,4'-bis(naphthylphenylphosphino)biphenyl (alpha-P-NPD) and 4,4'-bis(diphenylphosphino)biphenyl (P-DDB) were synthesized and the photophysical properties were evaluated and compared to P-STIL. The TAPs were shown to be sensitive to air oxidation both in solution and the solid state and that the origin of the high energy emission of P-STIL was from the oxide. Furthermore, all TAPs were shown to exhibit dual emission, which may result from different structural geometries about the P-atom in the excited state. Theses studies conclusively demonstrate that TAPs are not suitable as host materials fro blue dye-doped OLEDs, but the fully oxidized materials, which are more stable and emit at higher energy may be better candidates.
