Narrative Analysis Of "The Miami Herald"'S Coverage Of The Elian Gonzalez Saga, Kristi D. Caravella Jan 2001

Narrative Analysis Of "The Miami Herald"'S Coverage Of The Elian Gonzalez Saga, Kristi D. Caravella

Electronic Theses and Dissertations 2000 - 2009

This study examines the coverage of an event that took place mostly in Miami, Florida and was reported on by The Miami Herald for more than six months. There are several issues that are addressed in this thesis. The primary hypothesis of this analysis is that the coverage of the Elian Gonzalez custody battle as it appeared in The Miami Herald uses the same narrative techniques as those used in fictional melodrama or soap operas. John Fiske's theory of melodrama as developed from Brown (1987) and a similar model used by Fiske (1987) is used to compare the specified piece …

Nobles And Animals: Hierarchic Organization And Restoration In Nathaniel Hawthorne's "The House Of The Seven Gables", Gregory Douglas Cecere Jan 2001

Nobles And Animals: Hierarchic Organization And Restoration In Nathaniel Hawthorne's "The House Of The Seven Gables", Gregory Douglas Cecere

Electronic Theses and Dissertations 2000 - 2009

Since its publication, critics and readers have been unsatisfied with the conclusion of The House of the Seven Gables and have viewed it as either inconsistent or a failure. After an analysis of the language, actions, and patterns of imagery in this work, along with The Scarlet Letter and The Blithedale Romance, it had become clear that there is in fact consistency to the conclusion of this text. These patterns suggest Hawthorne's conception of an ultimate hierarchical organization that favors characters who exhibit specific attributes. This organizational pattern can be disrupted through methods of recreating hierarchical order. Such attempts create …

Pedagogy Of The Oppressor: Freirean Pedagogies In The Postmodern Classroom, Toni Perdita Francis Jan 2001

Pedagogy Of The Oppressor: Freirean Pedagogies In The Postmodern Classroom, Toni Perdita Francis

Electronic Theses and Dissertations 2000 - 2009

Since the publication of Paulo Freire's Pedagogy of the Oppressed , American educators have found use for his radical pedagogy that challenges traditional education practice. Freire considers current/traditional pedagogy to be "banking education"; he offers in its place a student-centered pedagogy in which both student and teacher participate in the process of learning. Freire's influence is most present in the field of composition studies where, in light of emerging postmodern theories, teachers find it necessary to alter Freire's work, but continue to value applications of his pedagogy such as dialogic classrooms, education for liberation, and problem-posing teaching. These processes and …

Numerical Simulations Of The Wave Bottom Boundary Layer Over Sand Ripples, Thomas P. Pierro Jan 2001

Numerical Simulations Of The Wave Bottom Boundary Layer Over Sand Ripples, Thomas P. Pierro

Electronic Theses and Dissertations 2000 - 2009

Surface gravity waves propagating in the nearshore produce an oscillatory freestream potential flow near the seabed and commonly cause regular two-dimensional sand ripples to be formed. The existence of the ripples causes complex turbulent flows to evolve in the boundary layer, which can dissipate significant energy from the surface waves. A time-dependent DNS model is used to solve the Navier-Stokes equations in three dimensions on a transformed curvilinear grid for specified wave parameters. When compared to smooth beds, simulations over wavy topographies demonstrate that turbulence is enhanced due to flow separation in the lee of the ripple crests. Shear instabilities …

Outlining A Theory About The Practical Use Of Theory: A Discourse-Practice Theoretic Analysis Of Academic Public Administration Symposia Genre, Cheedy Jaja Jan 2001

Outlining A Theory About The Practical Use Of Theory: A Discourse-Practice Theoretic Analysis Of Academic Public Administration Symposia Genre, Cheedy Jaja

Electronic Theses and Dissertations 2000 - 2009

Academic public administration (APA) supposedly provides theoretic and programmatic guidance for bureaucratic public administration (BPA). But in reality, a relationship best characterized as a gap between "theory" (APA) and "practice" (BPA) is deemed to exist between the two social practices. Scholars who have analyzed APA theoretic literature ascribed the theory-practice problematic to methodological inadequacies, the implication being that investment in appropriate social science methods would enhance the intellectual rigor and social utility of APA discursive works. To provide a much richer perspective on the theory-practice problematic, this study conceptualizes theoretic discourses as social actions. When scholars theorize, they invariably want …

Performance Evaluation Of A Ds/Cdma Packet Transmission System Under Rician Fading Channel Conditions, Christodoulos. Argyrides

Electronic Theses and Dissertations 2000 - 2009

This thesis is concerned with the performance analysis of a DS/CDMA packet radio system under Rician fading channel conditions. Analytic expressions are derived for the probability density functions and cumulative distribution functions of the total signal-to-interference ratio when considering mixed-type of interference sources. The users are divided into two groups: those that apply closed-loop power control and those that apply open-loop power control. Four different scenarios of power control were studied. The outage probability is evaluated for the four different cases of power control. A packet transmission protocol with forward error correction capabilities is considered, and the probability density functions …

Performance Impairments Of Bluetooth Systems Specified By External Emi And Transmissions From Piconet Neighbors, Victor Daniel Gadda Jan 2001

Performance Impairments Of Bluetooth Systems Specified By External Emi And Transmissions From Piconet Neighbors, Victor Daniel Gadda

Electronic Theses and Dissertations 2000 - 2009

This study presents computer simulations directed to address the performance of a baseband Bluetooth system. These simulations help to understand the performance impairments experienced by the Bluetooth systems in the presence of external electromagnetic interference (EMI) and interference that arises from piconet neighbors. The simulation results show that the effect of small scale fading is an important factor that decides the performance of a Bluetooth system. Additionally, it is shown that the interference from piconet neighbors or the interference that stems from devices belonging to the same piconet can be reduced by using frequency-hoping and time synchronization improvised within the …

Play, Problem-Solving And Tool Use: Individual Differences In Preschool Children, Jeffrey Michael Gredlein Jan 2001

Play, Problem-Solving And Tool Use: Individual Differences In Preschool Children, Jeffrey Michael Gredlein

Electronic Theses and Dissertations 2000 - 2009

While recent research has promoted play as an integral component of a child's cognitive functioning, tool-use has been relatively ignored in this discussion. It may be the case that these two abilities, especially constructive play and problem solving through the use of tools, emerging early in a child's life, have some connection in the formation of higher cognitive processing. From an evolutionary developmental perspective, three-year old children were observed in two free-play sessions and participated in a toy-retrieval task. Results indicate boys engaged in more constructive play than girls and were more likely to use tools to solve a problem. …

Population Status And Potential Storm Dispersal Events Of Malaclemys Terrapin In Florida Bay, Florida, Lindsay Anastasia Miller Jan 2001

Population Status And Potential Storm Dispersal Events Of Malaclemys Terrapin In Florida Bay, Florida, Lindsay Anastasia Miller

Electronic Theses and Dissertations 2000 - 2009

Mitochondrial DNA and nuclear microsatellite analyses were performed on Malaclemys terrapin data. These analyses investigated the genetic variation among subspecies of M. terrapin throughout their range and sought to determine if hurricane mitigated dispersal occurs among populations of a single subspecies, M.t. rhizophorarum. The 700bp mtDNA fragment, ND4-Leu, provided only 1bp transition, and the 421bp D-loop, DES1-DES2, revealed no genetic variation between the seven subspecies. Four polymorphic loci were examined for the microsatellite analyses. These analyses revealed an average pairwise RST of 0.018. This indicates very close genetic identities between the two temporally sampled populations before and after Hurricane Georges. …

Redefining The Pastoral In Contemporary Literature Through The Works Of Flannery O'Connor, Pamelyn. Jongbloed Jan 2001

Redefining The Pastoral In Contemporary Literature Through The Works Of Flannery O'Connor, Pamelyn. Jongbloed

Electronic Theses and Dissertations 2000 - 2009

The pastoral form is one of the oldest in the literary tradition. Historically, the definition of "pastoral" was limited to eclogues and idylls that epitomize a simple way of life, usually with shepherds as their subject. Over time, the pastoral genre has undergone numerous metamorphoses that retain some aspects of a simplistic vision, while contradicting the more complex matters that help to define the human condition. These transformations have allowed for pastoral motifs set in direct opposition to everyday life in order to exemplify human frailties. In Flannery O'Connor's works, the simplicities of natural southern settings are in direct contrast …

Resource Guide For Parents And Classroom Teachers Educating Special Education Students To Increase Appropriate Communication With All Individual Education Program (Iep) Team Members, Amy Thomasson Nast

Electronic Theses and Dissertations 2000 - 2009

Historically, individuals with special needs have been isolated from society and educational opportunities. Though the professional care for these individuals improved in two hundred years, only since the passage of Public Law 94-142, in the past twenty-seven years, have the needs and accomplishments of special needs individuals been made public. Based on ten years in the classroom, one special educator experienced the need for parents and classroom teachers to have a resources reference for educating special needs individuals and to improve the communication among parents, classroom teachers and special educators. Each group should have an understanding of some history of …

Scattering And Response Green's Function Modeling Of A Fluid-Loaded Coated Cylindrical Shell, Carole. Treffot

Electronic Theses and Dissertations 2000 - 2009

An acoustic compliant coating is applied on a fluid-loaded structure to control the radiated pressure, by decoupling the fluid medium from the vibrating surface. In this thesis the problem of an infinite cylindrical shell immersed in a fluid and entirely covered with an acoustic compliant layer, excited either by a ring force or an incident acoustic plane wave is considered. To model this problem two different approaches are used. The first one, which is available in the literature, is based on multi-layer shell theory. In this approach the scalar and the vector potential formulation are used to solve for the …

Soul Bubba: President Clinton's Use Of The Rhetoric Of Inclusion To Ensure The Loyalty Of The Congressional Black Caucus, Sandra Elizabeth Bernard-Bastien Jan 2001

Soul Bubba: President Clinton's Use Of The Rhetoric Of Inclusion To Ensure The Loyalty Of The Congressional Black Caucus, Sandra Elizabeth Bernard-Bastien

Electronic Theses and Dissertations 2000 - 2009

Clinton's success in engendering loyalty in the African-American, despite his failure to deliver socio-economic and political benefits, presents us with an apparent paradox. The contention is that the answer to this paradox could be found in the rhetorical style and strategies habitually employed by Clinton when speaking to African-Americans. What Clinton said to black America is important, but how he said it, is even more so. Through a critical examination of his eight speeches to the Congressional Black Caucus' Annual Dinner, using rhetorical theory, this research examines how Clinton said what he said. In utilizing the critical approach that examines …

Secondary Orality In "Their Eyes Were Watching God" And "The Color Purple", Africa Ragland Fine Jan 2001

Secondary Orality In "Their Eyes Were Watching God" And "The Color Purple", Africa Ragland Fine

Electronic Theses and Dissertations 2000 - 2009

The differences between orality and literacy have been explored by theorists who have focused mainly on the differences in the nature of communication once writing is introduced. However, other theorists have challenged the theory that those characteristics are separate and independent, and there is an argument that the relationship between oral and written communication is not a dichotomy, but a continuum when elements of both can coexist. This idea leads to theory of secondary orality, which describes communication that encompasses both oral and literate elements. Two modern novels, Zora Neale Hurston's Their Eyes Were Watching God and Alice Walker's The …

Synthesis Characterization And Ion Exchange Properties Of Aluminum Phosphonates, Rupert Garth Mccormack Jan 2001

Synthesis Characterization And Ion Exchange Properties Of Aluminum Phosphonates, Rupert Garth Mccormack

Electronic Theses and Dissertations 2000 - 2009

Three aluminum organophosphonate compounds; aluminum phenylphosphonate, aluminum octylphosphonate, and aluminum octadecylphosphonate, have been synthesized by refluxing aluminum nitrate with an excess of the appropriate organophosphonic acid in aqueous, methanol, or butanol solvents respectively. Each of these compounds was found to have pillared layered structures and ligand to metal ratios of 2:1. Additionally, these compounds were shown to exhibit cation exchange properties. In contrast to that observed for conventional cation-exchange resins, the exchange capacities of these compounds are larger for small cations, such as Li+ and Na+, than for larger ions such as Na+ and K+. The results indicate a size …

Target Signature For A Periodic Structure Using A Low-Frequency Broadband Side-Scan Simulator, Jerrold Edward Gilbert Dietz Jan 2001

Target Signature For A Periodic Structure Using A Low-Frequency Broadband Side-Scan Simulator, Jerrold Edward Gilbert Dietz

Electronic Theses and Dissertations 2000 - 2009

Many acoustic targets of interest contain features that are periodic in space. This thesis demonstrates that a chirp waveform, 2 kHz to 12 kHz, can detect repetitive structures with periods in the range of 0.125 m to 0.75 m. As aspect angle increases from 0 deg to 90 deg, a frequency shift in the range of 830 Hz to 4800 Hz will occur as the period decreases from 0.75 to 0.125 m. It follows that, spectral analysis can aid in target identification. A sonar propagation model has been developed to simulate the acoustic backscattered energy of a target with periodic …
