The Opening Section of Isang Yun's My Land My People: A Cross-Section of Korean and Western Musical Features

The Opening Section of Isang Yun's My Land My People: A Cross-Section of Korean and Western Musical Features

Date: May 2006
Creator: Choi, Woohyuk
Description: Isang Yun's oratorio My Land My People is organized in four movements, and is scored for orchestra, solo voice and choir. Movements are titled as follows: Rjoksa (History), Hyon-Shil I (Presence I), Hyon-shil II (Presence II), and Mi-rae (Future). This document only covers from measures 1-38 of the first section of the first movement of this work. Even though this work is atonal, the composer emphasizes a harmonically moving, tonal sonority: interval class five includes perfect 4th and 5th, quintal-quartal harmony and authentic cadence moving dominant to tonic. Also, in this document, a comparison with Korean traditional music elements is included to support Isang Yun's musical features.

Opening the Door to Meaning-Making in Secondary Art History Instruction

Opening the Door to Meaning-Making in Secondary Art History Instruction

Date: May 2006
Creator: Stroud, Elizabeth J.
Description: Each day countless numbers of high school students remain standing at the threshold of the door to meaningful learning in art history because of traditional authoritative instructional methods and content. With the keys of feminist pedagogy, interactive teaching methods, and the new art histories, the teacher can now unlock that door and lead students to personally relevant learning on the other side. A case study using both qualitative and quantitative research methods was conducted in a secondary art history classroom to examine the teacher's pedagogical choices and the degree to which they enable meaningful and relevant student learning. The analysis of multiple sources of data, including classroom observations, revealed statistically significant correlations between the teacher's instructional methods and the content, as well as their impact on student meaning-making.

Operant Procedures in Marital Treatment

Operant Procedures in Marital Treatment

Date: August 1973
Creator: Hickok, James E.
Description: The ability of marital partners to directly change a currently unhappy marriage to a happy one may be a function of each individual's conscious awareness of the topography, frequency, and other parameters of his own behaviors, as well as the effects or consequences these behaviors bring to bear on his spouse. This study was an attempt to combine the use of relevant behavioral awareness and a token economy to rehabilitate a marriage in crisis.

Opinions of Turkish immigrants living in Houston about the conflict between secularism and Islam in Turkey.

Opinions of Turkish immigrants living in Houston about the conflict between secularism and Islam in Turkey.

Date: August 2008
Creator: Balkan, Betul
Description: This study was designed to examine the opinions of Turkish immigrants living in the Houston metropolitan area about the conflict between secularism and Islam in Turkey. The study examined the role of the practice of religion on the opinions about the clash between secularism and Islam. A final sample consisted of 40 immigrants recruited through purposeful and snowball sampling. In-depth interviews and a survey including screening questions were conducted. The results indicated that practice of religion has a partial impact on the opinions of Turkish immigrants about the conflict between secularism and Islam. Future research should further examine if the experience of living abroad for a long period influence Turkish immigrants' opinions about the same issue.

Optical Transparent Pmma Composite Reinforced By Coaxial Electrospun Pan Hollow Nanofibers

Optical Transparent Pmma Composite Reinforced By Coaxial Electrospun Pan Hollow Nanofibers

Date: May 2013
Creator: Antoine, Donley
Description: Electrospinning has been recognized as an efficient technique for the fabrication of polymer fibers. These electrospun fibers have many applications across a broad range of industries. In this research, optical transparent composites were successfully fabricated by embedding polyacrylonitrile (PAN) hollow nanofibers into poly (methyl methacrylate) (PMMA) matrix. The hollow PAN nanofibers were prepared by coaxial electrospinning. The PAN was used as the shell solution, and the mineral oil was used as the core solution. The resulting fibers were then etched with octane to remove the mineral oil from the core. The hollow PAN fibers were then homogeneously distributed in PMMA resins to fabricate the composite. The morphology, transmittance and mechanical properties of the PAN/PMMA composite were then characterized with an ESEM, TEM, tensile testing machine, UV-vis spectrometer and KD2 Pro Decagon device. The results indicated that the hollow nanofibers have relatively uniform size with one-dimensional texture at the walls. The embedded PAN hollow nanofibers significantly enhanced the tensile stress and the Young's modulus of the composite (increased by 58.3% and 50.4%, respectively), while having little influence on the light transmittance of the composite. The KD2 Pro device indicated that the thermal conductivity of the PMMA was marginally greater than the ...

Optimal Access Point Selection and Channel Assignment in IEEE 802.11 Networks

Optimal Access Point Selection and Channel Assignment in IEEE 802.11 Networks

Date: December 2004
Creator: Park, Sangtae
Description: Designing 802.11 wireless networks includes two major components: selection of access points (APs) in the demand areas and assignment of radio frequencies to each AP. Coverage and capacity are some key issues when placing APs in a demand area. APs need to cover all users. A user is considered covered if the power received from its corresponding AP is greater than a given threshold. Moreover, from a capacity standpoint, APs need to provide certain minimum bandwidth to users located in the coverage area. A major challenge in designing wireless networks is the frequency assignment problem. The 802.11 wireless LANs operate in the unlicensed ISM frequency, and all APs share the same frequency. As a result, as 802.11 APs become widely deployed, they start to interfere with each other and degrade network throughput. In consequence, efficient assignment of channels becomes necessary to avoid and minimize interference. In this work, an optimal AP selection was developed by balancing traffic load. An optimization problem was formulated that minimizes heavy congestion. As a result, APs in wireless LANs will have well distributed traffic loads, which maximize the throughput of the network. The channel assignment algorithm was designed by minimizing channel interference between APs. The ...

Optimism, Delay Discounting, and Physical Exercise: The Role of Delay Discounting on Individual Levels of Exercise

Optimism, Delay Discounting, and Physical Exercise: The Role of Delay Discounting on Individual Levels of Exercise

Date: August 2010
Creator: Smith, Lauren Marie
Description: Deciding to exercise requires trade-offs between immediate and delayed benefits. These momentary decisions may be moderated by personality such that patterns of individual behavior emerge. The aim of the current study was to determine if higher levels of optimism and lower levels of delay discounting were related to exercise frequency. A sample of 360 undergraduate students completed a survey study related to understanding the choices made by undergraduates and how other factors relate to their decision-making. The survey included measures of optimism, delayed discounting, and self-reported exercise frequency in four domains: cardiovascular, resistance, sports, active lifestyle. Hierarchical linear regression was used to examine optimism and delay discounting as predictors of exercise frequency. Optimism and delay discounting were negatively correlated, but neither was related to exercise frequency. Furthermore, optimism and delay discounting were not significantly related to frequency spent in cardiovascular, resistance, or active lifestyle exercise. However, women scoring higher in delay discounting were more likely to participate in physical sports. The present study helps inform future research by showing potentially important psychosocial variables related to optimism, delay discounting, and exercise.
