Investigation Of Dynamically Coated Alumina Stationary Phases For Reversed-Phase High-Performance Liquid Chromatography, Veronica Ferguson Jan 1999

Investigation Of Dynamically Coated Alumina Stationary Phases For Reversed-Phase High-Performance Liquid Chromatography, Veronica Ferguson

Electronic Theses and Dissertations 1990 - 1999

Dynamically coated alumina (DCA) was prepared by pumping mobile phase containing methanol and concentration of 10mM Sodium Lauryl Sulphate (SLS), an anionic surfactant prepared in water, through a bare alumina column. The mechanism of separation of a test mixture were characteristic of reversed phase chromatography as evident in the decreased retention time as the percentage of methanol increased. However, the effects of changing the pH of the mobile phase on retention of solutes were different than that expected in reversed phase separations, indicating the presence of another retention mechanism. Excellent resolutions, peak shapes and peak symmetries were obtained using the …

Linking Dynamic Social Impact Theory To Social Representation Theory: The Emergence Of Social Representations Of Aggression Through Electronic Communication, Samantha Walker Jan 1999

Linking Dynamic Social Impact Theory To Social Representation Theory: The Emergence Of Social Representations Of Aggression Through Electronic Communication, Samantha Walker

Electronic Theses and Dissertations 1990 - 1999

Social representations consist of beliefs, values and norms that influence thought and behavior. Moscovici's Social Representation Theory provides an explanation for how social representations are formed, mutate, and survive, while Dynamic Social Impact Theory provides a framework by which to examine the emergence of macro-social phenomena from everyday communication (i.e., clustering, consolidation and continued diversity). Previous research has not examined, but has assumed, the processes by which social representations of aggression develop. The purpose of the present study was to examine social representations (SRs) of direct and indirect aggression and the process by which SRs emerge from interpersonal communication. Specifically, …

Larval Release By The Fiddler Crab Uca Thayeri: Timing And Cues Used Under Different Tidal Regimes, Kay Kellmeyer Jan 1999

Larval Release By The Fiddler Crab Uca Thayeri: Timing And Cues Used Under Different Tidal Regimes, Kay Kellmeyer

Electronic Theses and Dissertations 1990 - 1999

Hatching rhythms of intertidal crabs vary in timing with species, burrow position, tidal regimes and larval vulnerability. Most fiddler crabs time larval release with the nocturnal high fide. This is possible in semidiurnal tidal regimes because there are nocturnal high tides each lunar day. However, mixed tidal regimes have a semidiurnal and a diurnal period. During the diurnal phase high fide occurs in the afternoon. This variation in tidal inundation patterns may influence the timing of larval release. Comparisons between two populations of fiddler crab (Uca thayeri ), exposed to different tidal regimes, indicated they time larval release differently. The …

Jupiter Inlet I (8pb34): A Test Case In The Use Of Ceramic Frequencies And Discriminant Analysis In Determining Cultural Affinity, James Patrick Pepe Jan 1999

Jupiter Inlet I (8pb34): A Test Case In The Use Of Ceramic Frequencies And Discriminant Analysis In Determining Cultural Affinity, James Patrick Pepe

Electronic Theses and Dissertations 1990 - 1999

Many archaeological culture area models have been proposed for southern Florida. The most important reason for the number of alternative models may be a lack of precise means to evaluate them in relation to individual archaeological sites. This thesis addresses these problems using Jupiter Inlet I (8PB34) as an example. The relative frequencies of ceramic types from this site are compared to other sites with generally accepted cultural affiliations. The multivariate statistical technique known as discriminant analysis is used to directly compare comparable components from each site. This analysis reveals that archaeological areas in southern Florida can be determined fairly …

Leadership On Trial: A Study Of Nelson Mandela's Rhetorical Strategies, Katrika Nordraka Romer-Sterling Jan 1999

Leadership On Trial: A Study Of Nelson Mandela's Rhetorical Strategies, Katrika Nordraka Romer-Sterling

Electronic Theses and Dissertations 1990 - 1999

For over four decades the Apartheid system in South Africa deprived many black South Africans their right to democracy. However, Nelson Mandela's leadership strategies would prove effective in helping the Anti-Apartheid movement achieve its common goal of universal suffrage for all South Africans. This thesis explores what made Mandela's rhetoric as a leader so effective during his courtroom testimonies from the Treason Trial in 1956 and the Rivonia Trial in 1964. A new model is developed to analyze leadership characteristics: charisma, prophecy, creativity, pragmatism and prophecy proved to be significant strategies in making his leadership rhetoric so effective. The purpose …

Media Literacy And Hegemony: A Textual Analysis Of The Promotional Materials Offered By The Media Literacy Movement, Susan Ellen Holt Jan 1999

Media Literacy And Hegemony: A Textual Analysis Of The Promotional Materials Offered By The Media Literacy Movement, Susan Ellen Holt

Electronic Theses and Dissertations 1990 - 1999

We are living in a society where the commercial imperative of the mass media rather than the public interest is shaping our cultural environment. In response to the deleterious consequences of this phenomenon, many educators, parents, and community and religious groups are promoting the teaching of media literacy. This study looks for signs of hegemonic containment within the Media Literacy Movement, and delineates why an understanding of the political-economic implications of media institutions is vital in developing an effective media literacy program. The study concludes that the diversity found in the promotional texts of the Media Literacy Movement generally reflects …

Origins Of Everglades Drainage In The Progressive Era: Local, State And Federal Cooperation And Conflict, Jeffery Glenn Strickland Jan 1999

Origins Of Everglades Drainage In The Progressive Era: Local, State And Federal Cooperation And Conflict, Jeffery Glenn Strickland

Electronic Theses and Dissertations 1990 - 1999

During the Progressive Era, technical experts--state and independent engineers, United States Department of Agriculture scientists, and United States engineers increasingly influenced drainage and reclamation policy in central and southern Florida. Engineers agreed with the general method of drainage but at times disagreed over engineering specifics. The federal, state and local govemments were aware of the benefits associated with internal improvements, at the same time, however, they frequently fought over their control. Between the mid-nineteenth century and the early 1900s, drainage engineering knowledge and technology increased along with the role of the engineers. As a result, Florida's Progressive Governor Napoleon Bonaparte …

Rational Study Of Incompressible Turbulent Flows, Xiaoyan. Pu Jan 1999

Rational Study Of Incompressible Turbulent Flows, Xiaoyan. Pu

Electronic Theses and Dissertations 1990 - 1999

A new turbulence model is proposed in this dissertation for two-dimensional incompressible turbulent flows. The methodology used in the present study is a unilateral-statistical-average scheme with the concept of orthotropic eddy viscosity. This methodology has never been explored before in any research work of this nature. The distinguished feature of the unilateral-statistical-average scheme, compared to Reynolds averaging, is that the first-order information of the fluctuating velocity field is retained. This is achieved by dividing the fluctuating velocities into two groups and applying the average only to a single group. It is proved that the mean value of the fluctuating velocities …

Puzzle Of Transformation: Becoming A Nurse Practitioner, Patricia Mahoney Siccardi Jan 1999

Puzzle Of Transformation: Becoming A Nurse Practitioner, Patricia Mahoney Siccardi

Electronic Theses and Dissertations 1990 - 1999

The purpose of this study was to provide introductory knowledge about the value of narrative methods of teaching nurse practitioners and their transition to advanced practice. According to this study, becoming a nurse practitioner requires a paradigm shift. It demands that nurse practitioners remain grounded in nursing and yet, integrate enhanced critical thinking, diagnostic reasoning, and holistic humanistic caring. It was determined that the transition to the nurse practitioner role begins during the formal learning program and continues for several years after graduation. There is a learning curve involved in the transformation. Creating a new identity occurred slowly and incrementally …

Reporting Timeliness To Specialized International Human Rights Conventions: Cedaw, Dorothy Anne Quiggle Jan 1999

Reporting Timeliness To Specialized International Human Rights Conventions: Cedaw, Dorothy Anne Quiggle

Electronic Theses and Dissertations 1990 - 1999

Explanations of human rights compliance have been historically philosophical. Using timeliness of reporting as a measure of minimal compliance, there is an opportunity to examine compliance on a statistical level. This study introduces a theory asserting that compliance to specialized international human rights conventions depends on the representation of the protected group in a state's parliament. While examining the Convention to End All Forms of Discrimination Against Women (CEDAW), the study attempts to find a relationship between timely reporting to CEDAW and the level of female participation in parliament. The data fails to provide a statistically significant relationship due in …

Self-Calibration Of Laser Tracking Measurement System With Planar Constraints, Shui Hu Motaghedi Jan 1999

Self-Calibration Of Laser Tracking Measurement System With Planar Constraints, Shui Hu Motaghedi

Electronic Theses and Dissertations 1990 - 1999

Laser tracking coordinate measuring machines have the potential of continuously measuring three dimensional target coordinates in a large workspace with a fast sampling rate and high accuracy. Proper calibration of a laser tracking measurement system is essential prior to use of such a device for metrology. In the absence of a more accurate instrument for system calibration, one has to rely on self-calibration strategies. In this dissertation, a kinematic model that describes not only the motion but also geometric variations of a multiple-beam laser tracking system was developed. The proposed model has the following features: (1) Target positions can be …

Representations Of Values And Myths: A Narrative Analysis Of Three Television Domestic Situation Comedies, Stacy Caryn Seiser Jan 1999

Representations Of Values And Myths: A Narrative Analysis Of Three Television Domestic Situation Comedies, Stacy Caryn Seiser

Electronic Theses and Dissertations 1990 - 1999

One episode each of Fresh Prince of Bel-Air, Home Improvement, and Grace Under Fire was analyzed in attempt to understand how the episodes function of myth. Each of the domestic situation comedies, which consist of different types of families, present the myth of rite of passage. The episodes serve as a perceptual system; they rejuvenate a culture's reality; they appeal to our emotions; and they serve as exemplary models. The episodes were analyzed also to discern how different types of television families represent the values of rationality and emotionality. This analysis takes a narrative approach to consider the narrative probability …

Resisting The Others: Gender, Multiculturalism, And Social Identity In "Alien Resurrection", Joseph W. Sowers Jan 1999

Resisting The Others: Gender, Multiculturalism, And Social Identity In "Alien Resurrection", Joseph W. Sowers

Electronic Theses and Dissertations 1990 - 1999

Despite increasing racial diversity, the growth of multicultural awareness, and constantly changing ideas regarding gender roles in the United States, some Hollywood films still, directly and indirectly, stereotype "others" via images. Through methods of ideological film criticism, genre analysis of the science fiction film, some feminist theory and psychoanalysis, and the theory of the cyborg, this thesis argues that the Hollywood film Alien Resurrection is a cultural text which promotes racism, sexism, and Eurocentrism. Various film techniques, narrative elements, characters along with their development, and other aspects of the film serve to stereotype and confine those with multiple social identities.

Simple Model For Estimating Insolation From Goes Satellite Data, Emily Elaine Hopkins Jan 1999

Simple Model For Estimating Insolation From Goes Satellite Data, Emily Elaine Hopkins

Electronic Theses and Dissertations 1990 - 1999

South Florida summers are characterized by small intense convective storms which lead to extreme variations in local cloud cover. Estimating insolation from high-resolution satellite data accounts for these variations. A statistical model is presented for estimating incident solar radiation (insolation) using 1km x 1km resolution visible images from the GOES8 satellite. The model relates insolation to top-of-the-atmosphere radiation, readily available climate data, and cloud cover (from the satellite). Regression coefficients were developed and verified based on one month of insolation measurements from eight ground-based measurement stations operated by the South Florida Water Management District. The model allows almost continuous areal …

Smoking Or Not Smoking? A Logit Model Analysis, Mark Wayne Clarke

Electronic Theses and Dissertations 1990 - 1999

Since the beginning of President Clinton's administration, the cigarette industry has been under a lot of pressure to change the way they do business, how they advertise. This study was not intended to be for or against the issue of smoking but to see which variable affects smoking after the consumer makes the adult decision to smoke. Three different econometric analyses were used to come up with these results; Logit, OLS and Linear Probability Model. The findings indicate that variables like income, pack per week smoked, age, years smoking and gender are significant in determining if an adult consumer continues …

Softboard: A Web-Based Application Sharing System For Distance Learning, Krishna K. Adusumilli

Electronic Theses and Dissertations 1990 - 1999

The thesis describes the development of SoftBoard, a Web-based application sharing system. The main goal is to create a convenient tool for conducting virtual office hours for distance education over the Internet. It has been reported in the recent research papers that the current Internet is still not suitable for supporting collaborative tools such as audio/video conferencing and some advanced application sharing features as proclaimed by developers. However the Internet can be used to a lesser degree to fulfill needs of smaller application sharing systems which are not very network bandwidth intensive. SoftBoard is designed to be used over today's …

Constitutional Protection For Conversations Between Therapists And Clients, Paul E. Salamanca Jan 1999

Constitutional Protection For Conversations Between Therapists And Clients, Paul E. Salamanca

Missouri Law Review

People have long perceived a connection between mental and even physical illness and spiritual anguish. Yet, modem culture tends to view both types of illness from an increasingly medical perspective, seeking a genetic or environmental explanation. In most cases, this "medical model" is probably the best approach, even if it is imperfect. First, the purely medical explanation may be accurate. Second, even if it is not accurate, treating the symptoms of a disease with a spiritual source is probably far easier than treating the source itself. Ultimately, however, we must take note that disease is often not the result of …

Living A Lie: The Cost Of Qualified Immunity, Diana Hassel Jan 1999

Living A Lie: The Cost Of Qualified Immunity, Diana Hassel

Missouri Law Review

Throughout the modem civil rights era,' a silent struggle has been waged over civil liability for the violation of constitutional rights. The issues struggled with are what kinds of constitutional wrongs should be compensated and out of whose purse the damages should come. The mechanism for resolution of these issues has largely been the application of immunity defenses to civil rights remedies. A system of immunity defenses has been overlaid on the broad remedy provided by 42 U.S.C. § 1983 (hereinafter "Section 1983Y').2 A determination of the scope of the immunity defense-which government officials should get it and how much-has …

Fighting Corruption At The Local Level: The Federal Government's Reach Has Been Broadened, Kay Bartelson Perry Jan 1999

Fighting Corruption At The Local Level: The Federal Government's Reach Has Been Broadened, Kay Bartelson Perry

Missouri Law Review

The Racketeer Influenced and Corrupt Organizations Act (RICO)2 has produced a complex body of law. One area within the Act, conspiracy to violate the substantive provisions of RICO under Section 1962(d), has produced contrary views in the federal courts of appeals as to whether one must agree to personally commit the illegal, predicate acts, or whether one need only agree that another member of the conspiracy commit the acts. The United States Supreme Court has now settled the debate over this issue by holding that one need only agree that some member of the enterprise will commit the predicate act

Missouri Law Regarding Punitive Damages And The Doctrine Of Remittitur, Edward S. Stevens Jan 1999

Missouri Law Regarding Punitive Damages And The Doctrine Of Remittitur, Edward S. Stevens

Missouri Law Review

The imposition of punitive damages can devastate defendants, be they individuals or large corporations. Fortunately for these defendants, the jury does not have the final word on the amount of damages. This Note addresses the circumstances under which punitive damages are available in Missouri and when the doctrine of remittitur will be used so that damage awards comport with Missouri's prohibition against excessive awards and the Due Process Clause of the Fourteenth Amendment.

Analysis Of Multiplexed Atm Traffics: A Large-Deviation Theoretic Approach, Malathi. Palaniappa Jan 1999

Analysis Of Multiplexed Atm Traffics: A Large-Deviation Theoretic Approach, Malathi. Palaniappa

Electronic Theses and Dissertations 1990 - 1999

ATM multiplexing, (which is essentially a statistical multiplexing process with priority constraints) leads to a departure pattern of cells on the trunk (or bearer) line, characterized by the profiles of incoming traffics at the multiplexer. Such profiles are decided by the bit-rate variations and workload fluctuations of the associated sources, namely voice, data and video of the cells. Bit rate statistics of incoming traffic with priority constraints decide the clustered and/or non-clustered epochs of cells on the multiplexed fine. If the incoming traffic is delay-sensitive, it gets the priority in the multiplexing strategy and the associated cells inbiting no clusters; …

An Analysis Of Opportunities For Middle And High School Principals To Develop Public Speaking Skills For Effective Educational Leadership, Doris Stahl Agnon

Electronic Theses and Dissertations 1990 - 1999

Recognized leadership skills generally include communication skills and public speaking ability. Some children develop leadership and public speaking skills early in life. Some high schools and colleges emphasize public speaking. Adults frequently enroll in seminars such as Dale Carnegie programs or join organizations such as Toastmasters International. The researcher's own years of teaching and speaking experience have led her to believe in the potential value of public speaking for children, adults, and leaders in education organizations. Principals must speak competently and professionally. The purpose of this study was to determine how and when secondary school principals learned public speaking skills. …

Biosynthesis And Enzymology Of Secosteroids From Pseudopterogorgia Americana, Kevin Head Jan 1999

Biosynthesis And Enzymology Of Secosteroids From Pseudopterogorgia Americana, Kevin Head

Electronic Theses and Dissertations 1990 - 1999

9,11-Secosteroids are biologically active secondary metabolites from the marine invertebrate, Pseudopterogorgia americana. They are produced in vitro through an incubation of the steroid substrate with a cell-free extract of P. americana containing the necessary enzymes. Further optimization of this incubation was attempted through adjustment of incubation reagents and cofactors. The enzymes responsible for secosteroid production were partially purified through chromatography in an effort to isolate and purify these enzymes. Finally, experiments with radiolabeled gorgosterol led to the elucidation and isolation of a key secosteroid precursor, 9,11-dihydroxygorgosterol.
