Internet Advertising: New Media, New Models?, Eric James Karson Jan 1998

Internet Advertising: New Media, New Models?, Eric James Karson

Electronic Theses and Dissertations 1990 - 1999

Much of what we currently know about consumers' reaction to persuasive attempts (advertisements) comes from studying mass media communications which are largely one-way and image-centered. Internet-based advertising is neither given the focus on information and the ability to narrowly target such appeals (sites), as in direct marketing advertising. Given the emergence of Internet promotions, this is a substantial gap in our knowledge. This research seeks to both extend the boundaries of current direct marketing research (with its predominant focus on who will reply) and the domain of existing persuasion theories and models, attempting to gain a greater understanding of why …

Long-Term Survivorship In Women With Breast Cancer, Catherine Carpenter Marinak

Electronic Theses and Dissertations 1990 - 1999

The purpose of this study was to develop a theory of survivorship in long-term breast cancer patients, and a subsequent educational program to assist health care practitioners to guide these survivors. Seven women who had survived breast cancer for at least 10 years, were interviewed over a twelve month period. This qualitative study used Glaser & Strauss's grounded theory method to generate the process of survivorship for these women. The emergent core category, "life's journey" was characterized by two core variables, "caring with self" and "completing the grieving process". The following themes emerged from within these variables: coping strategies, maintaining …

Justice, Justice, Shall Ye Seek: Jewish Warriors In Spain, 1936-1939, Leslie. Shafer Jan 1998

Justice, Justice, Shall Ye Seek: Jewish Warriors In Spain, 1936-1939, Leslie. Shafer

Electronic Theses and Dissertations 1990 - 1999

In 1936, approximately three thousand Americans volunteered to aid Spain fight the Fascist rebellion of Fransisco Franco, and his German and Italian allies. About thirty percent of the volunteers were Jewish--a ratio so large as to be statistically improbable. Why were so many Jews impelled to go to Spain to fight for the Spanish Republic? Many were Communists, Socialists, unionists, and assorted antifascists, determined to stop the fascist threat in Europe. It was also seen as a chance to fight Hitler with bullets, not only words. The religion, culture and tradition of the Jews requires each person to seek justice …

New Materials Based On Metal Complexes Of Bis(Arylimino)Isoindoline, Jay Merlin Rosenberg Jan 1998

New Materials Based On Metal Complexes Of Bis(Arylimino)Isoindoline, Jay Merlin Rosenberg

Electronic Theses and Dissertations 1990 - 1999

Molecular architecture has been used to develop new materials with our knowledge of Bis(arylimino)isoindoline (BAII). Ni(BAII)2,\ Ni(NBAII)2 and Cu(NBAII)(OAc) complexes were prepared and studied using their Crystal packing diagrams and data in order to evaluate $\pi$-overlapping. It is believed that $\pi$-overlapping will occur in complexes with mono BAII substituted complexes and not di-substituted. The first steps have been made in the development of a polymeric BAII complex with the production of an oligomeric BAII (GBAII). The GBAII complex was analysis using a molecular device approach with the use of NMR instrumentation.

New Methods For Estimating Fractal Dimensions Of Coastlines, Jonathan David Klotzbach Jan 1998

New Methods For Estimating Fractal Dimensions Of Coastlines, Jonathan David Klotzbach

Electronic Theses and Dissertations 1990 - 1999

A coastline is an example of a statistically self-similar fractal. A standard characterization walks a ruler of fixed size along the coast and estimates fractal dimension from the power-law relationship between length and ruler size. Multiple intersection can lead to ambiguity in choosing the next step. The standard method always chooses the first intersection along the curve. Variations were developed to choose intersections which highlight geographic properties. The land method measures accessibility to the coast from land at each size while the water method probes water access. Measurements on sections of the East and West Coasts of the United States …

Numerical Study Of Bluff Body Aerodynamics By Vortex Method, Fusen. He Jan 1998

Numerical Study Of Bluff Body Aerodynamics By Vortex Method, Fusen. He

Electronic Theses and Dissertations 1990 - 1999

Vortex methods are grid-free; therefore, their use avoids a number of shortcomings of Eulerian, grid-based numerical methods for solving high Reynolds number flow problems. These include such problems as poor resolution and numerical diffusion. In vortex methods, the continuous vorticity field is discretized into a collection of Lagrangian elements, known as vortex elements. Vortex elements are free to move in the flow field which they create. The velocity field induced by these vortex elements is a solution to the Navier-Stokes equation, and in principle the method is suitable for high Reynolds number flows. In this dissertation, viscous vortex element methods …

Non-Linear Convection Of A Vortex Sheet Past A Cascade Of Airfoils, Den Berg Stanislas Franck Van Jan 1998

Non-Linear Convection Of A Vortex Sheet Past A Cascade Of Airfoils, Den Berg Stanislas Franck Van

Electronic Theses and Dissertations 1990 - 1999

The interaction of rotor turbulence with the stator is currently believed to be the predominant mechanism of noise radiation from turbofans in aircraft engines. This thesis presents a general method to compute unsteady 2-D potential flows past a cascade of airfoils. The procedure uses source and vortex distributions on the surface of the airfoils, creation of wakes downstream of the airfoils and non-linear convection of the perturbed flow. These features are designed to satisfy a condition of no-flow through the surface of the airfoils and the Kutta condition at the trailing edge of each of these airfoils. The investigation proves …

Notion Of Aggregation, Monika. Saksena Jan 1998

Notion Of Aggregation, Monika. Saksena

Electronic Theses and Dissertations 1990 - 1999

Most popular object-oriented modeling techniques (OOMTs) provide good support for the creation of conceptual models of system behavior and structure. A serious drawback of these techniques is that the concepts and notations used are not rigorously defined. This can lead to the creation of ambiguous models, and to disagreements over the proper use and interpretation of modeling constructs. An important modeling construct that is often loosely defined is aggregation. This thesis presents a precise characterization of aggregation that can help developers identify appropriate applications of the concept. Our characterization is the result of careful analysis of literature on conceptual modeling, …

Performance Of Multicarrier Ds Cdma Systems In A Nakagami Fading Channel, Jifang. Wang Jan 1998

Performance Of Multicarrier Ds Cdma Systems In A Nakagami Fading Channel, Jifang. Wang

Electronic Theses and Dissertations 1990 - 1999

The performance of a multicarrier DS CDMA system is evaluated over a Nakagami multipath fading channel. After the spreading process, the data sequence is applied to multiple carrier rather than a single carrier. Each carrier is provided a corralator in the receiver, and the maximal-ratio combiner is used for the corralator outputs. A bandlimited spreading waveforms are used for self-interference prevention. Robustness to multipath fading and narrow band interference suppression are achieved by this type of configuration. A comparison is made with a single carrier system in the presence of interference.

Optimizing Body-Proximate Telecommunications Devices In Direct And Multipath Propagation, Kazimierz. Siwiak Jan 1998

Optimizing Body-Proximate Telecommunications Devices In Direct And Multipath Propagation, Kazimierz. Siwiak

Electronic Theses and Dissertations 1990 - 1999

Body-proximate telecommunications devices are examined in both direct and multipath propagation. The study begins with a characterization of standard field strength sensitivity measurement methods for body-proximate telecommunications devices. Original measurements on a group of anthropometrically diverse people reveal that human adults, in a standard pose, are remarkably similar with respect to belt worn sensitivity performance, which motivates and justifies the use of an existing and a newly introduced light weight simulated human body device for testing, analysis and optimization of body worn telecommunications devices. Standard measurement methods using standard open air test ranges are established and validated by international transfers …

Phosphorus Uptake Rates Of A Ceratophyllum/Periphyton Community In A Southern Florida Freshwater Marsh, Kathleen C. Pietro Jan 1998

Phosphorus Uptake Rates Of A Ceratophyllum/Periphyton Community In A Southern Florida Freshwater Marsh, Kathleen C. Pietro

Electronic Theses and Dissertations 1990 - 1999

Net uptake rates of soluble reactive phosphate (SRP) of Ceratophyllum demersum and the dense periphyton mat associated with the macrophyte were calculated by measuring the disappearance of stable phosphorus (30, 50, 100, or 200 μg P/L) from the water column over a one-hour period each month for one year. Two seasonal periods were established based on average photosynthetically active radiation (PAR) and length of daylight through the year. ANOVA showed that the uptake rates were significantly affected (P < 0.05) by the amount of SRP added and were greater during the period of increased irradiance. Uptake rates continued to increase, even at spike concentrations equal to 10,000 μg P/L, indicating that maximum uptake was not achieved and that this plant complex is able to sequester even greater amounts of SRP. Estimates of the yearly uptake capabilities of the plant complex for a 525 ha wetland for the 30, 50, 100, 200 μg P/L spike treatments were 27, 55, 103, and 182 kg P/yr, respectively.

Quantum Cryptography And Minimum Disclosure Protocols, Jeffrey William Brooks Jan 1998

Quantum Cryptography And Minimum Disclosure Protocols, Jeffrey William Brooks

Electronic Theses and Dissertations 1990 - 1999

Minimum Disclosure Proofs by Protocol allow a prover to convince a verifier that the prover knows some verifiable secret information, without allowing the verifier to learn anything about the secret. Quantum Cryptography makes use of the quantum properties of light to allow the prover and the verifier to exchange secret information or to commit to a bit value. The ability to commit to a bit value will be exploited for a minimum disclosure proof by protocol. This thesis unites the two cryptography fields.

Progress Towards Genetic Engineering Of An Emf-Responsive Plasmid In Yeast, Karin Ann Crenshaw

Electronic Theses and Dissertations 1990 - 1999

Despite the many epidemiological studies which have shown some effects of EMF on biological systems, there has yet to be any data that indicates the molecular mechanisms by which this effect takes place. My goal was to genetically engineer a yeast strain that would have a clear biological effect to the EMF's. The strategy involved using a yeast strain which requires histone function from a plasmid, and the plasmid construct that has a Gal1 promoter controlling the histone function. The plasmid construct could then be engineered to contain a promoter sequence for a known EMF-repressed gene in yeast, which would …

Reconstructing Predevelopment Conditions Of Lake Worth Creek Using Historical Maps, Accounts, And Aerial Photography, Susan O. Farnsworth Jan 1998

Reconstructing Predevelopment Conditions Of Lake Worth Creek Using Historical Maps, Accounts, And Aerial Photography, Susan O. Farnsworth

Electronic Theses and Dissertations 1990 - 1999

This thesis develops a technique that combines the use of historical geography with photo interpretation and physical geography to reconstruct the predevelopment landcover of an urban area in southeastern Florida. This technique differs from traditional map making methods by utilizing Geographic Information System modeling procedures to create a conceptual map and test it against independent historical maps and accounts. Historical maps and accounts provided new information about the historic landscape that could not be deferred from present physiographic information. The resulting maps had more detail about the most highly altered areas than the conceptual map created from physiographic information.

Simulation Study Of Mobile Computing Protocols, Syed Alamdar Ahson

Electronic Theses and Dissertations 1990 - 1999

With the advent of cellular technology and portable computers we are on the verge of a new computing paradigm. This computing paradigm is now widely known as "mobile" or "nomadic" computing. Mobile systems frequently change their point of attachment to the network. Mobile computing systems also need to communicate with the existing pool of information and file servers. Mobility defies the very principles that the TCP/IP protocol suite is based on. We study the Internet Engineering Task Force (IETF) Mobile IPv4 protocol and find it to be a highly scale solution. We study some of the other proposed mobile IP …

The Effect Of Choline Supplementation On Maze Running Ability In Hypothyroid Rats, Jessica Ramer

Electronic Theses and Dissertations 1990 - 1999

The effects of perinatal hypothyroidism and perinatal choline supplementation on radial arm maze performance were assessed. Animals were made hypothyroid by the administration of propylthiouracil (PTU) to the mash of dams from prenatal day 15 until postnatal day 15. Choline chloride was administered prenatally in drinking water and postnatally through injections to the pups until day 24. Hypothyroid animals made significantly more reference and working memory errors than did euthyroid animals. Perinatal choline supplementation reduced the number of working memory errors, but not reference memory errors, in both euthyroid and hypothyroid animals.
