An Investigation of the Semantics of Active and Inverse Systems

An Investigation of the Semantics of Active and Inverse Systems

Date: May 1992
Creator: Yang, Lixin
Description: This study surveys pronominal reference marking in active and inverse languages. Active and inverse languages have in common that they distinguish two sets of reference marking, which are referred to as Actor and Undergoer. The choice of one series of marking over another is shown to be semantically and pragmatically determined.

An Investigation of the Traditional  Cante Jondo as the Inspiration for the Song Cycle  Five Poems of Garcia Lorca by Elisenda Fabregas

An Investigation of the Traditional Cante Jondo as the Inspiration for the Song Cycle Five Poems of Garcia Lorca by Elisenda Fabregas

Date: May 2004
Creator: Hobbs, Mary Etta
Description: The traditional cante jondo is a song unique to Andalusia as it developed from the "mosaic" of cultures that have inhabited its borders, including Arabs, Jews and Gypsies. The genre expresses the history of the region, reveals the typography of the landscape and cries the tears of its people. "Deep song," the translation for cante jondo, is the forerunner of the flamenco, but it is a communication of a dark soul rather than an exuberant entertainment. The original folk idiom is a medium less concerned with beauty than the cathartic release of pain of every day life. It expresses the soul of Andalusia. This study explores the history and the poetic and musical forms Andalusian cante jondo as the inspiration for the poetry of Federico Garcia Lorca set by Elisenda Fabregas in the song cycle, Five Poems of Garcia Lorca (1992). Lorca felt the validity of "deep song" and he was disturbed that it was being corrupted by commercialism and was afraid it would be lost to posterity. His goal was to preserve the essence of the song and lift it to an artistic plain. He saw folk music as the core of the national musical and literary identity in ...

An Investigation of the Use of Acrylic Polymer Paints in Printing Photographic Silk Screen Images

An Investigation of the Use of Acrylic Polymer Paints in Printing Photographic Silk Screen Images

Date: May 1972
Creator: Blue, Monte L.
Description: This study investigates the adaptability of plastic paints to photographic silk screen materials and methods. The problem was to experiment with and further develop another technique for the artist, the silk screening of photographic images directly onto the painting surface with acrylic polymer paint.

An investigation of the use of instructional simulations in the classroom as a methodology for promoting transfer, engagement and motivation.

An investigation of the use of instructional simulations in the classroom as a methodology for promoting transfer, engagement and motivation.

Date: August 2007
Creator: Lunce, Leslie Matthew
Description: Innovative educators seek technologies to facilitate or enhance the learning experience while taking nothing away from the message of instruction. Simulations have been shown to meet this requirement. While simulations cannot replace the teacher or the message of instruction, they can provide a deeper and more cognitively engaging learning experience. Classroom use of simulations has been ongoing since the 1960's. However, substantive research on their efficacy remains limited. What research has been conducted indicates that simulations possess great potential as aids to instruction. The author of this dissertation pursued this question focusing on whether simulations contribute to instruction by facilitating transfer, improved motivation and increased engagement. This dissertation documents a study in which instructional simulations were used in undergraduate science courses to promote engagement, transfer and knowledge-seeking behavior. The study took place at Midwestern State University (MSU), a public university located in north-central Texas with a student population of approximately 5,500. The study ran during the fall 2006 and spring 2007 terms. Samples consisted of students enrolled in GNSC 1104 Life / Earth Science during the fall term and GNSC 1204 Physical Science during the spring term. Both courses were offered through the Department of Science and Mathematics at MSU. ...

Investigation of Ultratrace Metallic and Organic Contaminants in Semiconductor Processing Environments

Investigation of Ultratrace Metallic and Organic Contaminants in Semiconductor Processing Environments

Date: May 1997
Creator: Xu, Fei, 1971-
Description: Detection of ultratrace levels of metallic ion impurities in hydrofluoric acid solutions and alkaline hydrogen peroxide solution was demonstrated using a silicon-based sensing electrode. The sensor's operation principle is based on direct measurements of the silicon open-circuit potential shift generated by the interaction between metallic ions and the silicon-based sensing surface. The new sensor can have practical applications in the on-line monitoring of microelectronic chemical processing. The detection of Ag+ content in KODAK waste water was carried out successfully by this novel sensor. Trace levels of organic impurities in the hydrofluoric acid solutions and in the cleanroom air were characterized by multiple internal reflection infrared spectroscopy (MIRIS) using an organics probe prepared directly from a regular silicon wafer.

An Investigation of Young Children's Awareness of Line and Line Quality in Art and Graphic Reproductions

An Investigation of Young Children's Awareness of Line and Line Quality in Art and Graphic Reproductions

Date: December 1994
Creator: Young, Jeffry R. (Jeffry Ray)
Description: The purpose of this study was to determine whether kindergarten children possess the ability to recognize, match, and discuss lines and line qualities. Using graphics and art reproductions, three matching tasks were constructed which examined young children's awareness of the line qualities of length, width, straightness, direction, movement, and uniformity. Graphics and art reproductions were also used to construct two tracing tasks employed to examine young children's awareness of actual and implied lines. The tasks were administered to 69 kindergarten students from four elementary schools in a public school district in the north central Texas area.

An Investigation to Determine Improvement in the Social Status of Children Through Concetrated Effort

An Investigation to Determine Improvement in the Social Status of Children Through Concetrated Effort

Date: 1950
Creator: Atkins, Thelma
Description: The problem of this study is an investigation of the development of social adjustment in thirty-three first-grade pupils in Gainesville, Texas, during 1949-1950. The purpose of the study is to determine each child's total readiness status at the beginning of the investigation, surround each with socializing experiences appropriate to his need, and then determine whether measurable benefits appear to result from his participation in the specific activities designed for social development.

Investigations in the Mechanism of Carbothermal Reduction of Yttria Stabilized Zirconia for Ultra-high Temperature Ceramics Application and Its Influence on Yttria Contained in It

Date: May 2014
Creator: Sondhi, Anchal
Description: Zirconium carbide (ZrC) is a high modulus ceramic with an ultra-high melting temperature and, consequently, is capable of withstanding extreme environments. Carbon-carbon composites (CCCs) are important structural materials in future hypersonic aircraft; however, these materials may be susceptible to degradation when exposed to elevated temperatures during extreme velocities. At speeds of exceeding Mach 5, intense heating of leading edges of the aircraft triggers rapid oxidation of carbon in CCCs resulting in degradation of the structure and probable failure. Environmental/thermal barrier coatings (EBC/TBC) are employed to protect airfoil structures from extreme conditions. Yttria stabilized zirconia (YSZ) is a well-known EBC/TBC material currently used to protect metallic turbine blades and other aerospace structures. In this work, 3 mol% YSZ has been studied as a potential EBC/TBC on CCCs. However, YSZ is an oxygen conductor and may not sufficiently slow the oxidation of the underlying CCC. Under appropriate conditions, ZrC can form at the interface between CCC and YSZ. Because ZrC is a poor oxygen ion conductor in addition to its stability at high temperatures, it can reduce the oxygen transport to the CCC and thus increase the service lifetime of the structure. This dissertation investigates the thermodynamics and kinetics of the YSZ/ZrC/CCC ...
