From Communicative Silencer To Responsive Listener: Participation And Public Dialogue In Benin, André Quenum

Electronic Theses and Dissertations

The interpretation explores the issue of participatory communication within the particular Beninese context of public dialogue by focusing on the communicative praxis of intellectual elite and by taking the public dialogue of the 1990 National Conference of Benin as a case study. The interpretive listening of such a situated participatory public dialogue results in the framing of two major metaphors: communicative silencer and responsive listener. First, the interpretation unveils that the possibility of broad participation in the democratization of Benin is compromised by a culture of silence in which intellectual elite become communicative silencers of the silenced communities including the …

A Quantitative Approach Towards Establishing Normal Csp Mrna Accumulation Patterns In Escherichia Coli K12, Khadijah Aisha Mitchell

Electronic Theses and Dissertations

The cold-shock response in Escherichia coli induces a set of 26 proteins that help ensure the efficiency of transcription, translation, and DNA replication at low temperatures. Some members of this group belong to the cold-shock protein (Csp) family. In Escherichia coli K12, there are 9 homologous csp genes named cspA-cspI. The Csp family in this strain is unusual because each gene has different mechanisms of induction and gene products. Various regulation studies have been performed on individual members of this family to help understand why so many homologues exist. No literature to date has ever looked at the mRNA expression …

Adolescent Female Embodiment As A Transformational Experience In The Lives Of Women: An Empirical Existential-Phenomenological Investigation, Allyson Havill

Electronic Theses and Dissertations

Adolescence can be a time of psychological vulnerability in the life cycle of a woman as she experiences multiple developmental changes. As articulated in the literature related to adolescent female development, a changing body may be at the heart of what can make this a time of profound transition for the adolescent girl as she attempts to negotiate alterations in her identity and self-concept, and consequently her social roles.

The purpose of this investigation of adolescent female embodiment was to understand the experience of adolescent girls as it relates to their changing bodies, and to explore the question of whether …

Enhancing Vocabulary Acquisition Through Synthetic Learning Experiences: Implementing Virtual Field Trips Into Classrooms, Alicia Sanchez

Electronic Theses and Dissertations

A Synthetic Learning Environment (SLE) the Virtual Field Trip (VFT) was designed to increase vocabulary acquisition and knowledge by utilizing simulation based technologies and leveraging sound educational findings. Vocabulary acquisition is considered a prerequisite to becoming a good reader and therefore a critical predictor of academic and lifelong success for early learners, however, teachers report that students lack the real world knowledge required for vocabulary knowledge. The VFT provides a meaningful context for anchored and situated instruction. Second grade students were assigned to either use the VFT or to listen to stories read aloud by a researcher on a video …

Experimental Techniques For Nonlinear Material Characterization: A Nonlinear Spectrometer Using A White-Light Continuum Z-Scan, Mihaela Balu

Electronic Theses and Dissertations

The main goal of this dissertation is to introduce and demonstrate a new method for the rapid determination of the nonlinear absorption spectra and the dispersion of the nonlinear refraction of optical materials in the visible and near IR spectral regions. However, conventional methods like, white-light continuum pump-probe and Z-scan techniques were used to measure the peak 2PA cross-sections for a number of commercially available photoinitiators. In the new method mentioned above, a high energy, broadband femtosecond white-light continuum is used to replace the single wavelength source conventionally used in a Z-scan experiment. In a Z-scan experiment, the transmittance of …

The Role Of Expectancies In Binge Eating Behavior, Jessica Larose

Electronic Theses and Dissertations

The central aim of the present study was to examine the role of expectancies in binge eating behavior. Two distinct statistical techniques were used to accomplish this goal. First, regression analyses were conducted using variables previously identified in the literature, as well as eating expectancies as measured by the Eating Expectancy Inventory (EEI). For both females and males, regression equations including expectancies accounted for a substantial portion of the variance in binge eating behavior. Second, memory modeling techniques were used to model the probable organization of eating expectancies. Memory modeling of hypothetical expectancy networks has lead to successful interventions in …

Hispanics' Attitudes Toward Seeking Counselingas A Function Of Psychosocial And Demographic Variables, Angela Rojas-Vilches

Electronic Theses and Dissertations

Using variables identified in the social science literature believed to influence attitudes toward seeking professional counseling, an attempt was made to develop a model for predicting Hispanics' willingness to obtain professional help. A second purpose of this study was to compare college students (n = 158) with their parents on their attitudes toward mental illness and toward seeking counseling. Among predictor variables, social stigma and the belief that mental illnesses are untreatable were the primary variables predicting attitudes toward seeking counseling. The more college students and their parents perceived there to be social stigma attached to those seeking therapy, and …

Electronic Theses and Dissertations

This paper is an analysis of American's opinions on government spending on Social Security. The main objectives were to analyze the effect of year and cohort membership on the likelihood for American's to say that they think the government is spending too little on Social Security. The data was obtained from the General Social Survey. Results of the analysis conclude that year is statistically significant in predicting the likelihood of those who say the government is spending too little on Social Security. When comparing every year to 1994, 1996 is the only year that year that respondents were less likely …

Hurricane Wind Speed And Rain Rate Retrieval Algorithm For The Stepped Frequency Microwave Radiometer, Ruba Amarin

Electronic Theses and Dissertations

This thesis presents the development and validation of the Hurricane Imaging Retrieval Algorithm (HIRA) for the measurement of oceanic surface wind speed and rain rate in hurricanes. The HIRA is designed to process airborne microwave brightness temperatures from the NOAA, Stepped Frequency Microwave Radiometer (SFMR), which routinely collects data during NOAA hurricane hunter aircraft flights. SFMR measures wind speeds and rain rates at nadir only, but HIRA will soon be integrated with an improved surface wind speed model for expanded utilization with next generation microwave hurricane imagers, such as the Hurricane Imaging Radiometer (HIRad). HIRad will expand the nadir only …

Radiation Studies Of The Tin-Doped Microscopic Droplet Laser Plasma Light Source Specific To Euv Lithography, Chiew-Seng Koay

Electronic Theses and Dissertations

Extreme ultraviolet lithography(EUVL) is being developed worldwide as the next generation technology to be inserted in ~ 2009 for the mass production of IC chips with feature sizes <35 nm. One major challenge to its implementation is the development of a 13.5 nm EUV source of radiation that meets the requirements of current roadmap designs of the source of illumination in commercial EUVL scanners. The light source must be debris-free, in a free-space environment with the imaging EUV optics that must provide sufficient, narrow spectral band EUV power to print 100 wafers/hr. To meet this need, extensive studies on emission from a laser plasma source utilizing tin-doped droplet target was conducted. Presented in this work, are the many optical techniques such as spectroscopy, radiometry, and imaging, that were employed to characterize and optimize emission from the laser plasma source State of the art EUV spectrographs were employed to observe the source's spectrum under various laser irradiation conditions. Comparing the experimental spectra to those from theory, has allowed the determination of the Sn ion stages responsible for emitting into the useful EUV bandwidth. Experimental results were compared to spectral simulations obtained using Collisional-Radiative Equilibrium (CRE) model, as well. Moreover, extensive measurements surveying source emission from 2 nm to 30 nm, which is the region of the electromagnetic spectrum defined as EUV, was accomplished. Absolutely calibrated metrology was employed with the Flying Circus instrument from which the source's conversion efficiency (CE)--from laser to the useful EUV energy--was characterized under various laser irradiation conditions. Hydrodynamic simulations of the plasma expansion together with the CRE model predicted the condition at which optimum conversion could be attained. The condition was demonstrated experimentally, with the highest CE to be slightly above 2%, which is the highest value among all EUV source contenders. In addition to laser intensity, the CE was found to depend on the laser wavelength. For better understanding, this observation is compared to results from simulations. Through a novel approach in imaging, the size of the plasma was characterized by recording images of the plasma within a narrow band, around 13.5 nm. The size, approximately 100 ìm, is safely within the etendue limit set by the optical elements in the EUV scanner. Finally, the notion of irradiating the target with multiple laser beams was explored for the possibility of improving the source's conversion efficiency.

The Effect Of Social Presence On Teacher Technology Acceptance, Continuance Intention, And Performance In An Online Teacher Professional Development Course, Jo Smith

Electronic Theses and Dissertations

The purpose of this study was to determine if the Technology Acceptance Model (TAM) could explain the relationship between teacher's acceptance of an online teacher professional development course and their continuance intentions regarding online teacher professional development (oTPD). This study focused on the perceptions of the teachers as opposed to the design or implementation of oTPD. The participants (N=517) were mostly teachers (88.8%) enrolled in a statewide online course to provide classroom teachers with the latest knowledge of research-based instructional reading strategies. The course was offered over a 10-14 week period during the Spring 2006 semester through a public state …

Pluralism And Presidential Campaign Finance Reform: A Policy Analysis Of Campaign Finance Reform From Feca To Bcra, Tully Dillon

Electronic Theses and Dissertations

One of the underlying themes in American politics is that the addition of campaign finance laws at the presidential election level will have a negative relationship with amount of influence and money in campaigns and the amount of regulation. In other words, as regulation goes up the amount of money and influence will decrease. However, with the recent 2004 presidential election this concept has surely been shown to be problematic, at least at the outset. The purpose of this thesis is to examine this relationship and to further expand upon the limited knowledge of this sub-field of political science. This …

Interviews of ASPD personnel were conducted to understand user perceptions of AVL. Based on the ANOVA results, trends indicate that …

In Transition: An Activity Theoretical Analysis Examining Electronic Portfolio Tools' Mediation Of The Preservice Teacher's Authoring Experience, Rebecca Fiedler

Electronic Theses and Dissertations

Co-chairs: Dr. Donna Baumbach Dr. Gail West Background: Electronic portfolios are increasingly used to make critical decisions about teacher candidates and program accreditation. Adoption rates for portfolios are at nearly 90% for schools, colleges, and departments of education (Salzman, Denner, & Harris, 2002). Over 50% of institutions who rated themselves or were nominated by others as exemplary users of electronic portfolios use web-based database-driven electronic portfolio systems (Strudler & Wetzel, 2005b; Wetzel & Strudler, 2005b). There is a paucity of theory-driven, systematic, rigorous research on electronic portfolios and a need for in-depth, context-aware research on such initiatives. Purpose: To explicate …

Fade Statistics For A Lasercom System And The Joint Pdf Of A Gamma-Gamma Distributed Irradiance And Its Time Derivative, Frida Stromqvist Vetelino

Electronic Theses and Dissertations

The performance of lasercom systems operating in the atmosphere is reduced by optical turbulence, which causes irradiance fluctuations in the received signal. The result is a randomly fading signal. Fade statistics for lasercom systems are determined from the probability density function (PDF) of the irradiance fluctuations. The expected number of fades per second and their mean fade time require the joint PDF of the fluctuating irradiance and its time derivative. Theoretical integral expressions, as well as closed form, analytical approximations, were developed for the joint PDF of a gamma-gamma distributed irradiance and its time derivative, and the corresponding expression for …
