Business/it Alignment: the Impact of Incentive Plans on the Development of Shared Vision

Description: This study, utilizing Preston and Karahanna’s framework for shared vision development and Agency Theory, explores the impact of vision development factors and factors associated with incentive plans on shared vision and alignment. Results of the study confirm the strong relationship between shared vision and alignment, and indicate that having an effective management team is important with respect to developing and maintaining shared vision and alignment within the organization. Several vision development factors such as using the language of the business, participation on the top management team (TMT), and having knowledge of the business impact shared vision through their influence on teamwork. Also, results of this study suggest that participation on the TMT by the CIO/IT leader is more important than the individual’s position in the organizational hierarchy. In addition, attributes associated with incentive plans such as achievable and clear measures, measures linked to organizational goals, measures that align the interests of the individual with those of the organization, regular plan reviews, and using a balanced scorecard approach with respect to incentive plan design positively impact teamwork and shared vision. For practitioners, this highlights the importance of incentive plans as powerful tools that can be used to reinforce shared vision, effective teamwork, and alignment within the organization. Also, the CIO/IT leader needs to be knowledgeable of the business and must fill the role of both a technologist as well as an enterprise leader. This person must be an evangelist communicating the value and benefits of IT to the rest of the organization.

The effects of selected color phenomena in a basic presentation to college students

Description: The problem of this study was to ascertain the effects of selected color phenomena upon the identification and comparison of color by college students. Instruments used for this study were the Snellen Visual Acuity Chart, which measures crudely the the binocular visual activity of an individual; Pseudo-Isochromatic Plates for Testing Color Perception, which roughly determine red-green color deficiency; and the "Isoline Color Phenomena Perception Presentation," which determines how an individual identifies or compares selected color phenomena.

The Myth of Emmetropia: Perception in Rhetorical Studies

Description: This thesis sets up the problem of sight in a visual society, with the aim to answer how the visual makes itself known. The conversation starts on visuality, and where there are gaps in understanding. The first of two case studies examines the absence of sight, or blindness, both literal and figurative. Through a study of blind photographers and their work, this chapter examines the nature of perception, and how biological blindness may influence and inform our understanding of figurative blindness. The second case study examines what the improvement of damaged sight has to say about the rhetorical nature of images. This chapter examines various means of improving sight, using literal improvements to sight to understand figurative improvements in vision and perception. The fourth and final chapter seeks to sum up what has been discovered about the rhetorical nature of sight through the ends of the spectrum of sight.

Seismic Image Segmentation

Description: Image segmentation is a standard low-level task in computer vision. We demonstrate how the segmentation of seismic images can assist in geologic interpretation. An image segmentation technique is applied to images of the acoustic impedance. A salient feature of the resulting segments is that the hydrocarbon-bearing regions are characterized by a finer segmentation than the other regions. A modified apparent polarity attribute is introduced, and images of this attribute are segmented. The boundaries of the resulting segments pass through the minima and maxima of the acoustic impedance in a manner that allows us to segment the acoustic impedance image into layers of high and low acoustic impedance. Our methods can assist in segmentation of acoustic impedance images according to lithology or geologic facies.

A REAL TIME COAL CONTENT ORE GRADE (C2OG) SENSOR

Description: This fourth quarterly technical report discusses the progress made on a machine vision technique for determining coal content and ore grades. Work done this quarter has been primarily devoted to improving the apparatus and data collection system. This includes a totally new optical setup, continued development of a new imaging spectrometer, and software improvements. Additionally, interest from other mining operations has arisen and sample of titanium and talc have now been obtained for preliminary analysis. Work is ongoing with coal samples, although it appears a more diverse sampling may be required. With the improvements now being made in the system, much faster and more user-friendly data collection and analysis will result in faster and better turn-around for sample analysis.

NASA's Space Vision: Business Case for Prometheus 1 Needed to Ensure Requirements Match Available Resources

Description: A letter report issued by the Government Accountability Office with an abstract that begins "In 2003, the National Aeronautics and Space Administration (NASA) initiated the Prometheus 1 project to explore the outer reaches of the Solar System. The Prometheus 1 spacecraft is being designed to harness nuclear energy that will increase available electrical power from about 1,000 watts to over 100,000 watts and enable the use of electric propulsion thrusters. Historically, NASA has had difficulty implementing some initiatives. NASA's failure to adequately define requirements and quantify the resources needed to meet those requirements has resulted in some projects costing more, taking longer, and achieving less than originally planned. Prometheus 1 will need to compete for NASA resources with other space missions--including efforts to return the shuttle safely to flight and complete the International Space Station. GAO was asked to determine (1) whether NASA is establishing initial justification for its investment in the Prometheus 1 project and (2) how the agency plans to ensure that critical technologies will be sufficiently mature at key milestones."

Development of a chemical vision spectrometer to detect chemical agents.

Description: This paper describes initial work in developing a no-moving-parts hyperspectral-imaging camera that provides both a thermal image and specific identification of chemical agents, even in the presence of nontoxic plumes. The camera uses enhanced stand-off chemical agent detector (ESCAD) technology based on a conventional thermal-imaging camera interfaced with an acousto-optical tunable filter (AOTF). The AOTF is programmed to allow selected spectral frequencies to reach the two dimensional array detector. These frequencies are combined to produce a spectrum that is used for identification. If a chemical agent is detected, pixels containing the agent-absorbing bands are given a colored hue to indicate the presence of the agent. In test runs, two thermal-imaging cameras were used with a specially designed vaporizer capable of controlled low-level (low ppm-m) dynamic chemical releases. The objective was to obtain baseline information about detection levels. Dynamic releases allowed for realistic detection scenarios such as low sky, grass, and wall structures, in addition to reproducible laboratory releases. Chemical releases consisted of dimethylmethylphosphonate (DMMP) and methanol. Initial results show that the combination of AOTF and thermal imaging will produce a chemical image of a plume that can be detected in the presence of interfering substances.

Iterative Self-Dual Reconstruction on Radar Image Recovery

Description: Imaging systems as ultrasound, sonar, laser and synthetic aperture radar (SAR) are subjected to speckle noise during image acquisition. Before analyzing these images, it is often necessary to remove the speckle noise using filters. We combine properties of two mathematical morphology filters with speckle statistics to propose a signal-dependent noise filter to multiplicative noise. We describe a multiscale scheme that preserves sharp edges while it smooths homogeneous areas, by combining local statistics with two mathematical morphology filters: the alternating sequential and the self-dual reconstruction algorithms. The experimental results show that the proposed approach is less sensitive to varying window sizes when applied to simulated and real SAR images in comparison with standard filters.

Localization of Color Discrimination in the Human Cerebral Cortex

Description: This study investigated color discrimination as a possible localized function of right or left cerebral hemispheres in humans. Previous studies have shown conflicting results. Studies implicating the left hemisphere have contaminated color discrimination with verbal-symbolic ability. Other studies implicating the right hemisphere emphasized color-matching ability. This study pointed out the importance of response latency as well as accuracy and also the importance of testing the data for meeting the assumptions of the statistical technique utilized. It was concluded that color discrimination is normally a right-hemisphere function in right-handed individuals. Differences in individual ability, although large, were not found to be systematically related to sex or eye dominance, but may be learned individual differences. The study further pointed out the inappropriateness of referring to a major or dominant cerebral hemisphere without stipulating which function is being considered.
