Theses and Dissertations

The purpose of this study was to research the feasibility of establishing a southern New Jersey chapter of the Public Relations Society of America (PRSA).

Some major findings included: (a) more than fifteen southern New Jersey members of PRSA are interested in joining a southern New Jersey chapter; (b) more than thirty public relations practitioners, not holding membership in PRSA, are interested in joining a southern New Jersey chapter of PRSA.

The findings of the author's survey concluded that establishing a southern New Jersey chapter of PRSA is feasible.

Persuasion Theories In The Practice Of Public Relations In The 1990'S, Susan E. Owens

Theses and Dissertations

The purpose of this study was to present ways in which persuasion theories are currently used in public relations and how persuasion theories could be used in public relations. Some public relations textbooks devote a chapter or section to persuasion theories and how they relate to public relations. The public relations practitioner needed a publication that expanded on these theories and provided cases of how they are used in public relations today.

To research persuasion theories and current application of them, current textbooks and periodicals were reviewed at several libraries. The searches at Rowan College, Richard Stockton College and Ocean …

The newspapers chosen for the study were the: New York Times, Los Angeles Times, Wall Street Journal, Washington Post, Washington Times and Atlanta Journal and Constitution.

Articles from these newspapers from June 1993 through July 1994 were analyzed for their bias against Christian Conservatives or lack thereof. Samples were selected from the newspapers during the time frame chosen when one or more of the following five descriptors appeared in the newspaper text: Christian …

Development Of Synthetic Soils For Sorption Mass Transfer Model Validation, Thomas P. De Venoge

Theses and Dissertations

Existing sorption models often fail to describe grain scale sorption because of an inability to define the diffusion domain. A proposed improved model required testing to determine model validity. The testing method used a synthetic media of known geometry such that the distribution of sorption sites was known. Sorption rate data was obtained using batch experiments with the media. Data was used in comparison against model predicted rates. Fined sorption site distributions were compared to real distributions obtained by controlling sorbent geometries. Comparison determined model performance in fitting known distributions. The focus of this study was to (1) determine what …

Deconvolution From Wavefront Sensing Using Optimal Wavefront Estimators, Scott R. Maethner

Theses and Dissertations

A cost effective method to improve the space surveillance mission performance of United States Air Force (USAF) ground-based telescopes is investigated and improved. A minimum variance wavefront estimation technique is used to improve Deconvolution from Wavefront Sensing (DWFS), a method to mitigate the effects of atmospheric turbulence on imaging systems that does not require expensive adaptive optics. Both least-squares and minimum variance wavefront phase estimation techniques are investigated, using both Gaussian and Zernike polynomial elementary functions. Imaging simulations and established performance metrics are used to evaluate these wavefront estimation techniques for a one-meter optical telescope. Performance metrics include the average …

The New Logic Of Hypertext: Electronic Documents, Literary Theory, And Air Force Publications, Gordon G. Geison

Theses and Dissertations

Hypertext systems offer electronic links that can instantly join related documents with the click of a mouse. Some observers predict that in the next few years hypertext will become the predominate technology of communication. Such a revolutionary transformation of our culture's basic system for sharing information is bound to have a profound and wide-ranging impact. At this early stage in hypertext's evolutionary development, no empirical study can be expected to capture the long-term implications of this new technology. An exploratory survey was distributed to 100 large corporations to gather their initial assessment of the revolutionary implications of hypertext. The results …

Air Force Media Use And Conformance With Media Richness Theory: Implications For E-Mail Use And Policy, Heather L. Adams

Theses and Dissertations

Communication has become a major aspect of a manager's job. When communicating, they are faced with many choices of what media to use - some include face-to-face, telephone, e-mail, or written. Managerial effectiveness can improve if managers make appropriate media choices. Thus, it is important to study how Air Force managers perceive media and what kind of choices they are making based on those perceptions. Media Richness Theory suggests that media choices are affected by content reasons, situational reasons, and symbolic reasons. This study examined Air Force managers and found they conform highly with Media Richness Theory in their media …

Whose Information Is It Anyway? An Argument For Information Stewardship, Trevor W. Plant

Theses and Dissertations

Information is an important resource for businesses and government, with information quality influencing decision quality, and highlighting our need to manage our information well: as a resource. Information Resource Management (IRM) has as its goal the management of information as a resource, but has not been implemented with the level of success expected. Problems with the implementation of IRM are indicated by the presence of redundant or inconsistent data, inability to share information across systems, and difficulty finding the information on systems. We propose that these difficulties are related to behaviours linked to perceived ownership of corporate information by organisational …

Digital Rosetta Stone: A Conceptual Model For Maintaining Long-Term Access To Digital Documents, Steven B. Robertson

Theses and Dissertations

Due to the rapid evolution of technology, future digital systems may not be able to read and/or interpret the digital recordings made by older systems, even if those recordings are still in good condition. This thesis addresses the problem of maintaining long-term access to digital documents and provides a methodology for overcoming access difficulties due to technological obsolescence. A review was conducted to determine the long-term access methods that have already been suggested by other researchers. These previously suggested methods are then combined with other ideas that were encountered and conceived while performing research for this project. The combination of …

Perceptual Fidelity For Digital Color Imagery, Curtis E. Martin

Theses and Dissertations

The problem of measuring the fidelity of digital color images in a manner that corresponds to human perceptual assessments is addressed. Experiments are performed to validate human visual system (HVS) models, which provide access to a 'perceptual space' in which visual distortions may be measured, and then a model is proposed for assessing the perceptual fidelity of digital color image. Color Mach bands are produced in the first experiment, demonstrating that, as in the brightness channel, low spatial frequency attenuation occurs in the chromatic channels of the HVS. In the second experiment, a correlation between the chromatic channels of the …

Electrical Characterization Of Intrinsic And Induced Deep Level Defects In Hexagonal Sic, James D. Scofield

Theses and Dissertations

Deep level defects in hexagonal SiC were studied using digital deep level transient spectroscopy (DLTS) methods over the temperature range of 100 to 800 deg K. New centers were found in bulk and epitaxial 6H-SiC with ionization energies between 0.38 to 1.3 eV, and levels from 0.2 to 0.856 eV were identified in 4H-SiC epitaxy. Direct correlation between inequivalent lattice sites was identified for energetic pairs associated with both vanadium and ion implanted Mg impurities. Nonradioative carrier capture mechanisms were studied and deep level trapping was found to proceed via lattice relaxation multi-phonon emission, indicating efficient electronic lattice coupling in …

Collaborative Workspaces Within Distributed Virtual Environments, William D. Wells

Theses and Dissertations

In warfare, be it a training simulation or actual combat, a commander's time is one of the most valuable and fleeting resources of a military unit. Thus, it is natural for a unit to have a plethora of personnel to analyze and filter information to the decision-maker. This dynamic exchange of ideas between analyst and commander is currently not available within the distributed interactive simulation (DIS) community. This lack of exchange limits the usefulness of the DIS experience to the commander and his troops. This thesis addresses the commander's isolation problem through the integration of a collaborative workspace within AFIT's …

Mass Transport Of Volatile Organic Compounds Between The Saturated And Vadose Zones, Monte S. Harner

Theses and Dissertations

Volatile organic compounds (VOCs) dissolved in the saturated zone are transported into the vadose zone primarily by gaseous phase diffusion. If the saturated zone is remediated, VOCs present in the vadose zone may become a secondary source of contamination for the groundwater. The amount of VOCs that remain in the vadose zone is dependent on site hydrology, soil properties, and the chemical properties of the contaminants. The purpose of this study was to determine what conditions caused VOC concentrations in the vadose zone to significantly recontaminate the saturated zone. A one-dimensional numerical model was developed to investigate the transport of …

Study Of Desorption Of Contaminant From Synthetic Soil, Kung-Fu Hwang

Theses and Dissertations

A better understanding of sorption and desorption processes could improve estimates of time and cost required for remedial activities, exposure times and health risk, and bioavailability. Conventional rate-limited sorption models do not accurately define the diffusion domain at the grain scale. Heyse (1994) proposed the multiple sites in series (MSS) model, which allows more general description of the geometry of the sorption domain than the classical spherical or discrete distributions. A version of this model was tested by deVenoge (1996). The model was able to accurately simulate sorption rate data, but could not estimate unique geometry parameters. This research is …
