Stable Spatial Solitons In Semiconductor Optical Amplifiers, Erdem Ultanir Jan 2004

Stable Spatial Solitons In Semiconductor Optical Amplifiers, Erdem Ultanir

Electronic Theses and Dissertations

A spatial soliton is a shape invariant self guided beam of light or a self induced waveguide. Spatial solitons appear as a result of the balance of diffraction and nonlinear focusing in a system. They have been observed in many different conservative media in the last couple of years. Solitons are ubiquitous, because of the probability of using their interactions in optical data processing, communications etc. Up to now due to the power required to generate the solitons, and the response times of the soliton supporting media, these special waves of nature could not penetrate the applications arena. Semiconductors, with …

Aggression In Lesbian And Bisexual Relationships, Jennifer Rae Parham Jan 2004

Aggression In Lesbian And Bisexual Relationships, Jennifer Rae Parham

Electronic Theses and Dissertations

For years, researchers, clinicians, and those working with victims/survivors of domestic abuse have overlooked the issue of same-sex partner aggression among lesbians and bisexual women. Through in-depth interviews with 19 women who identify themselves as either lesbian or bisexual, information was documented in this study demonstrating the severity of issues of power and control among some same-sex partners, as well as some if the dynamics that are unique to same-sex abusive relationships. Patterns of abuse within same-sex relationships often mirror those that are so commonly associated with partner aggression among heterosexual couples, and therefore demonstrate not only the need for …

Explaining Partisan Change Among Catholics In The American Electorate, Christopher Vincent, Muro Jan 2004

Explaining Partisan Change Among Catholics In The American Electorate, Christopher Vincent, Muro

Electronic Theses and Dissertations

This thesis examines data from the National Election Studies in order to assess the significant determinants of the political behavior of Catholics in the American electorate. A complex array of variables including religious commitment, generational differences, social status, and policy attitudes account for limited change in partisan alignment among American Catholics. The analyses expose the long-term, durable nature of partisan attachment, as older generation Catholics who register as actively committed to their religion also remain committed Democrats. Therefore, older Catholics have not been part of the broader ideological realignment which has taken place among other religious adherents, namely evangelical and …

Social Underdevelopment In Sub-Saharan Africa, Michelle L. Wingo Jan 2004

Social Underdevelopment In Sub-Saharan Africa, Michelle L. Wingo

Electronic Theses and Dissertations

For the past thirty years Africa has produced a more noticeably inferior reserve of human capital than other developing regions. This is puzzling because at the inception of independence, the future of Africa looked promising. However, during the 1970s both the political and economic situation in Africa began to deteriorate, and since 1980, the aggregate per capita GDP in sub-Saharan Africa has declined at almost one percent per fiscal year. Thirty-two countries are poorer now than they were twenty years ago, and sub-Saharan Africa is now the lowest-income region in the world despite the fact that during the last two …

Population Churn: The Migration Flow Of Florida, Marguerite Cashen Jan 2004

Population Churn: The Migration Flow Of Florida, Marguerite Cashen

Electronic Theses and Dissertations

Recent research has focused attention on the concerns of migration in and out of Florida and within the counties themselves. In 1949, Cape Canaveral was established and the boom was on. The character of the state dramatically transformed after 1965, when plans were announced to convert twenty-seven thousand acres of swampland into Walt Disney World. Since then, Orlando's evolution is divided into two eras: before and after Walt Disney World. Orlando has changed from a quiet town whose function was to service the surrounding citrus growing regions in a sparsely populated Orange County to a booming metropolis. Has the growth …

Improving Metacomprehension And Learning Through Graduated Concept Mod, Eleni Kring Jan 2004

Improving Metacomprehension And Learning Through Graduated Concept Mod, Eleni Kring

Electronic Theses and Dissertations

Mental model development, deeper levels of information processing, and elaboration are critical to learning. More so, individuals' metacomprehension accuracy is integral to making improvements to their knowledge base. In other words, without an accurate perception of their knowledge on a topic, learners may not know that knowledge gaps or misperceptions exist and, thus, would be less likely to correct them. Therefore, this study offered a dual-process approach that aimed at enhancing metacomprehension. One path aimed at advancing knowledge structure development and, thus, mental model development. The other focused on promoting a deeper level of information processing through processes like elaboration. …

The Impact Of Selected Socio-Demographic, Travel-Related And Psychogra, Nichakarn Peerapatdit Jan 2004

The Impact Of Selected Socio-Demographic, Travel-Related And Psychogra, Nichakarn Peerapatdit

Electronic Theses and Dissertations

Several researchers have attempted to understand the tourism expenditure patterns from the traveler's perspective (Cai, Hong, and Morrision, 1995; Dardis, et al., 1981; Prais and Houthakker,1971; Sheldon and Mak , 1987; Jang, et al.,2003). However, an examination of the previous studies indicates that only limited understanding of the traveler's expenditure patterns has been provided either because of only anecdotal evidence in the studies, or because of their failure to examine the impacts of the factors affecting expenditure patterns. This study examined the effects of socio-demographic, travel-related, and psychographic variables on travel expenditures. The expenditure patterns included lodging, meals and restaurants, …

Dispersion-Managed Breathing-Mode Semiconductor Mode-Locked Ring Laser, Bojan Resan Jan 2004

Dispersion-Managed Breathing-Mode Semiconductor Mode-Locked Ring Laser, Bojan Resan

Electronic Theses and Dissertations

A novel dispersion-managed breathing-mode semiconductor mode-locked ring laser is developed. The "breathing-mode" designation derives from the fact that intracavity pulses are alternately stretched and compressed as they circulate around the ring resonator. The pulses are stretched before entering the semiconductor gain medium to minimize the detrimental strong integrating self-phase modulation and to enable efficient pulse amplification. Subsequently compressed pulses facilitate bleaching the semiconductor saturable absorber. The intracavity pulse compression ratio is higher than 50. Down chirping when compared to up chirping allows broader mode-locked spectra and shorter pulse generation owing to temporal and spectral semiconductor gain dynamics. Pulses as short …

The Lack Of Diversity On The Bench In Florida's State Courts, Verlinda Wells Jan 2004

The Lack Of Diversity On The Bench In Florida's State Courts, Verlinda Wells

Electronic Theses and Dissertations

Diversity in the judiciary is essential to ensure impartiality, public confidence, and the perception that all members of society are represented on the bench. Minorities and women are significantly underrepresented as judges in Florida in proportion to their numbers in the general population. Because we live in an increasingly global world, diversity is best described when people of different races, colors, ethnicity and genders work to develop a mutual respect for each other. It was important to use diversity in this research because it required recognition, understanding, and acceptance of the special contribution that each member of a group can …

The Effects Of Stimulus Motion On Contrast Sensitivity: Dynamic Sensi, Merrill Zavod Jan 2004

The Effects Of Stimulus Motion On Contrast Sensitivity: Dynamic Sensi, Merrill Zavod

Electronic Theses and Dissertations

Static Visual Acuity (SVA) has been called into question for some time as a measure of overall visual system function and as a predictor of performance on real-life tasks requiring vision (i.e., operating an automobile). Specifically, it has been pointed out that the targets employed in most SVA testing (high contrast, stationary letters) are an insufficient analog to actual targets encountered in everyday activities, which are often in motion and/or of less-than-perfect contrast. In addition, the size-threshold methodology typically used to measure SVA is incongruent with current theories of a multi-channel visual system. Dynamic Visual Acuity (DVA) and Contrast Sensitivity …

Towards Direct Writing Of 3-D Photonic Circuits Using Ultrafast Lasers, Arnaud Zoubir

Electronic Theses and Dissertations

The advent of ultrafast lasers has enabled micromachining schemes that cannot be achieved by other current techniques. Laser direct writing has emerged as one of the possible routes for fabrication of optical waveguides in transparent materials. In this thesis, the advantages and limitations of this technique are explored. Two extended-cavity ultrafast lasers were built and characterized as the laser sources for this study, with improved performance over existing systems. Waveguides are fabricated in oxide glass, chalcogenide glass, and polymers, these being the three major classes of materials for the telecommunication industry. Standard waveguide metrology is performed on the fabricated waveguides, …

Il Pazzia D'Innamorati: A Commedia Dell'arte, Jennifer Hart Jan 2004

Il Pazzia D'Innamorati: A Commedia Dell'arte, Jennifer Hart

Electronic Theses and Dissertations

My thesis proposal is to research, workshop, develop, script, direct and produce my own commedia dell'arte. This proposal stems from my desire to explore improvisational comedy theoretically and practically. The genre of commedia dell'arte is not only timeless, but continues to further our ability to create characters and scenario for future projects as the root of improvisation. By coupling research on commedia components (character, lazzi and scenario) with the creation of an improvisational troupe, a commedia piece will be developed, documented and performed. The first part of my thesis will consist of research on the history of improvisational comedy. The …

The Merry Wives Of Windsor: A University Actress's Approach To The Role Of Mistress Ford, Brook Akya Hanemann Jan 2004

The Merry Wives Of Windsor: A University Actress's Approach To The Role Of Mistress Ford, Brook Akya Hanemann

Electronic Theses and Dissertations

Art is too ethereal a thing to judge by tangible measure. There is no scale to weigh a performance on, no level to gauge a character’s balance, no plumb line to measure its depth. No critic can appoint an allotment of stars to represent the worth of a production, and the audience, though a vital participant within the performance experience, cannot act as Jury and deliberate together to reach an absolute verdict of approval or disapproval. How then can an actor go about working towards giving a successful performance? The Merry Wives of Windsor was written at a time when …

Getting To The Pulp Of Haruki Murakami's Norwegian Wood: Translatability And The Role Of Popular Culture, Jacquelyn Zuromski Jan 2004

Getting To The Pulp Of Haruki Murakami's Norwegian Wood: Translatability And The Role Of Popular Culture, Jacquelyn Zuromski

Electronic Theses and Dissertations

Haruki Murakami's Norwegian Wood (1987) veers from his favored detective-fiction genre by offering readers a 1960s coming-of-age romance, a story whose plot nonetheless spins around the protagonist seeking out his personal identity. The conflicts between Japanese tradition and modern, global perspectives are illustrated through the inclusion of popular culture elements such as music, literature and films. This thesis seeks to show how the novel's references to popular culture of the 1960s combine to help the protagonist establish an identity for himself as well as his place within the universal community. First, though, the project explores the impact of the translatability …

Women's Experiences With Distance Education, Jane Elizabeth Moody Jan 2004

Women's Experiences With Distance Education, Jane Elizabeth Moody

Electronic Theses and Dissertations

This thesis examines issues that affect women in online learning, and discusses four women's particular experiences in the University of Central Florida's distance learning program. Online education involves aspects of support and communication that may affect women's learning experiences either positively or negatively. Distance learning may also allow women to pursue their education while still taking care of their families and outside work. In order to get a better idea of how distance learning impacts women, I discuss several studies that examine how distance learning affects women in particular. I identify three areas from this literature that seem to be …

Transforming Learning Into A Constructive Cognitive And Metacognitive, Haydee Cuevas Jan 2004

Transforming Learning Into A Constructive Cognitive And Metacognitive, Haydee Cuevas

Electronic Theses and Dissertations

This study explored the effectiveness of embedding a guided, learner-generated instructional strategy (query method), designed to support learners' cognitive and metacognitive processes, within the context of a computer-based complex task training environment (i.e., principles of flight in the aviation domain). The queries were presented as "stop and think" exercises in an open-ended question format that asked learners to generate either simple (low-level elaboration) or complex (high-level elaboration) sentences from a list of key training concepts. Results consistently highlighted the benefit of presenting participants with low-level elaboration queries, as compared to the no-query or high-level elaboration queries. In terms of post-training …

Pseudomonas Aeruginosa 1244 Pilin Glycan: Surface Location And Induction Of Immune Response, Erica Sentgeorge Jewell

Electronic Theses and Dissertations

P. aeruginosa 1244 pilin is covalently modified with a carbohydrate moiety, which is structurally similar to the lipopolysaccharide (LPS) O-antigen repeating unit. Studies were conducted using transmission electron microscopy and scanning electron microscopy with the monoclonal glycan-specific antibody, 11.14, to determine the location of the glycan. It was found that the glycan is evenly distributed over the entire surface of the pilin fiber and not restricted to the tip. The immunogenicity of the pilin glycan was also studied. Rabbits were immunized with pure LPS-free pili to determine if the pili produce anti-LPS antibodies. The serum obtained from the rabbits was …
