Saving Minnesota: Current Issues in Historic Preservation
In recent years, historic preservation in Minnesota has established a significant record. To be sure, numerous efforts extending over the past century have saved many individual historic properties. For example, the John H. Stevens house (1850) was moved from downtown Minneapolis to Minnehaha Park for preservation in the 1890s; the Henry Sibley house (1836) in Mendota and the Seppman Mill (1863) in Blue Earth County were preserved in the early 20th century. But only in the last three decades have preservationists looked broadly at the full range of types of historic properties and worked to preserve them not only as museum sites but for a variety of purposes.
During the 1960s, the Field Archeology Act and the Historic Sites Act created a state policy of recognizing and protecting archeological sites and historic properties throughout Minnesota. At the federal level, the National Historic Preservation Act of 1966 established the National Register of Historic Places and a State Historic Preservation Office (SHPO) in each state to implement the many aspects of the national program. (In Minnesota, the SHPO is a department of the Minnesota Historical Society.) Today, over 4,000 Minnesota properties representing all 87 counties are included in the National Register. Considerable activity is being undertaken by local heritage preservation commissions, county and local historical societies, and other statewide and local groups with preservation missions.
Over time, the preservationist\u27s attention has broadened from a few significant houses to a wide spectrum of properties - industrial structures, ships, farmsteads, landscapes, skyscrapers - with locally significant properties recognized as crucial to our national heritage. Historic preservation is, of course, an ongoing activity, continually facing challenges ranging from changing notions of what\u27s important to the natural forces of rust and rot. As the state enters the 1990s several preservation issues merit particular attention
Assessment of transient negative affect in synesthesia
Title from PDF of title page, viewed on August 22, 2011Dissertation advisor: Christopher T. LovelaceVitaIncludes bibliographical references (p. 71-79)Thesis (Ph.D.)--Dept. of Psychology. University of Missouri--Kansas City, 2011The purpose of this dissertation was to investigate how synesthesia may influence affect and sensorimotor gating in synesthetes. Synesthesia is the phenomenon in which a sensory experience triggers a conscious perception that is in addition to perceptions most people would experience in response to the stimulus. The type of synesthetic experience involving colors for letters and/or numbers is indicative of grapheme to color synesthesia; the most frequently reported type of synesthesia. For example, a synesthete may report seeing the color green in response to hearing or seeing a particular number or letter. Anecdotal reports by synesthetes describe negative affect when viewing a number or letter in a color that does not match (i.e., is incongruent) the synesthete's automatic perceptions. In addition, many reports by synesthetes indicate a greater propensity for experiencing ―sensory overload‖ than non-synesthetes. It was predicted that briefly viewing an incongruent grapheme would produce a transient negative affective state, temporarily increasing the magnitude of startle reflex as measured by eyeblinks among grapheme -> color synesthetes. Results did not support an interaction effect involving Presence of Synesthesia and Picture Condition, F(2,23) = 1.35, p >.05. Although magnitude of startle was greater for grapheme -> synesthetes than when viewing an incongruent grapheme compared to viewing a congruent grapheme or in the baseline (no picture) condition, these results were not statistically significant. It was also predicted that, when examining sensorimotor gating in synesthetes and non-synesthetes with prepulse inhibition (PPI) as the index, synesthetes would show less PPI, indicating increased sensory overload susceptibility. This hypothesis was not supported. Although synesthetes did not display reduced PPI, significantly more synesthetes than non-synesthetes reported experiencing sensory overload, and significantly higher levels of sensory sensitivity and sensation avoiding.Introduction -- Review of Literature -- Methodology -- Results -- Discussion -- Appendix A.

Teaching Scholarly Writing to Doctoral Students: Giving Novice Scholars a Running Start
Students entering doctoral programs in adult education and related fields often experience culture shock. Perhaps the biggest adjustment is learning how to think and write like a scholar. This paper examines how involvement by doctoral students in a formal scholarly writing project during their first semester of study influenced their subsequent doctoral experience and professional work
Behavorial Assessment of Synesthetic Perception: Color Perception and Visual Imagery in Synesthesia
Title from PDF of title page, viewed on November 12, 2010.Thesis advisor: Christopher T. Lovelace, Ph.D.Vita.Includes bibliographic references (pages 41-44).Thesis (M.A.)--College of Arts and Sciences. University of Missouri--Kansas City, 2010.This study examined vividness of visual mental imagery and color discrimination ability in synesthesia. It was hypothesized that participants with synesthesia would have higher overall scores on the Vividness of Visual Imagery Questionnaire (VVIQ) and participants with colored synesthetic experiences would have lower Total Error Scores (TES) on the Farnsworth Munsell 100-Hue test (FM 100 test). Results revealed a significant difference between groups on the FM 100 test [F(2,28) = 2.67, p =.03], with participants with colored synesthetic perceptions having lower TES scores (M = 20.40) than synesthetes without colored concurrents (M = 34.00) and participants without synesthesia (M = 34.63). An independent samples t-test revealed no significant differences between synesthetes and nonsynesthetes and overall VVIQ scores [t(30) = -1.46, p=.16]. These results indicate that synesthetes with colored concurrents may have better color discrimination ability than non-synesthetes and synesthetes without colored concurrents.Abstract -- List of Illustrations -- List of Tables -- Introduction -- Review of Literature -- Methodology -- Results -- Discussion -- Appendix A.

High transonic speed transport aircraft study
An initial design study of high-transonic-speed transport aircraft has been completed. Five different design concepts were developed. These included fixed swept wing, variable-sweep wing, delta wing, double-fuselage yawed-wing, and single-fuselage yawed-wing aircraft. The boomless supersonic design objectives of range=5560 Km (3000 nmi), payload-18 143 kg (40 000lb), Mach=1.2, and FAR Part 36 aircraft noise levels were achieved by the single-fuselage yawed-wing configuration with a gross weight of 211 828 Kg (467 000 lb). A noise level of 15 EPNdB below FAR Part 36 requirements was obtained with a gross weight increase to 226 796 Kg (500 000 lb). Although wing aeroelastic divergence was a primary design consideration for the yawed-wing concepts, the graphite-epoxy wings of this study were designed by critical gust and maneuver loads rather than by divergence requirements. The transonic nacelle drag is shown to be very sensitive to the nacelle installation. A six-degree-of-freedom dynamic stability analysis indicated that the control coordination and stability augmentation system would require more development than for a symmetrical airplane but is entirely feasible. A three-phase development plan is recommended to establish the full potential of the yawed-wing concept
Applications of a Forward-Looking Interferometer for the On-board Detection of Aviation Weather Hazards
The Forward-Looking Interferometer (FLI) is a new instrument concept for obtaining measurements of potential weather hazards to alert flight crews. The FLI concept is based on high-resolution Infrared (IR) Fourier Transform Spectrometry (FTS) technologies that have been developed for satellite remote sensing, and which have also been applied to the detection of aerosols and gases for other purposes. It is being evaluated for multiple hazards including clear air turbulence (CAT), volcanic ash, wake vortices, low slant range visibility, dry wind shear, and icing, during all phases of flight. Previous sensitivity and characterization studies addressed the phenomenology that supports detection and mitigation by the FLI. Techniques for determining the range, and hence warning time, were demonstrated for several of the hazards, and a table of research instrument parameters was developed for investigating all of the hazards discussed above. This work supports the feasibility of detecting multiple hazards with an FLI multi-hazard airborne sensor, and for producing enhanced IR images in reduced visibility conditions; however, further research must be performed to develop a means to estimate the intensities of the hazards posed to an aircraft and to develop robust algorithms to relate sensor measurables to hazard levels. In addition, validation tests need to be performed with a prototype system
Airborne Forward-Looking Interferometer for the Detection of Terminal-Area Hazards
The Forward Looking Interferometer (FLI) program was a multi-year cooperative research effort to investigate the use of imaging radiometers with high spectral resolution, using both modeling/simulation and field experiments, along with sophisticated data analysis techniques that were originally developed for analysis of data from space-based radiometers and hyperspectral imagers. This investigation has advanced the state of knowledge in this technical area, and the FLI program developed a greatly improved understanding of the radiometric signal strength of aviation hazards in a wide range of scenarios, in addition to a much better understanding of the real-world functionality requirements for hazard detection instruments. The project conducted field experiments on three hazards (turbulence, runway conditions, and wake vortices) and analytical studies on several others including volcanic ash, reduced visibility conditions, in flight icing conditions, and volcanic ash

Experimental Validation of a Forward Looking Interferometer for Detection of Clear Air Turbulence due to Mountain Waves
The Forward-Looking Interferometer (FLI) is an airborne sensor concept for detection and estimation of potential atmospheric hazards to aircraft. The FLI concept is based on high-resolution Infrared Fourier Transform Spectrometry technologies that have been developed for satellite remote sensing. The FLI is being evaluated for its potential to address multiple hazards, during all phases of flight, including clear air turbulence, volcanic ash, wake vortices, low slant range visibility, dry wind shear, and icing. In addition, the FLI is being evaluated for its potential to detect hazardous runway conditions during landing, such as wet or icy asphalt or concrete. The validation of model-based instrument and hazard simulation results is accomplished by comparing predicted performance against empirical data. In the mountain lee wave data collected in the previous FLI project, the data showed a damped, periodic mountain wave structure. The wave data itself will be of use in forecast and nowcast turbulence products such as the Graphical Turbulence Guidance and Graphical Turbulence Guidance Nowcast products. Determining how turbulence hazard estimates can be derived from FLI measurements will require further investigation
