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.

Oprah and her Book Club: More than Mass Media Money-Maker

Oprah and her Book Club: More than Mass Media Money-Maker

Date: May 1999
Creator: Jones, Carrie S. Lilly
Description: With her Book Club, talk show host Oprah Winfrey has used the relatively new technology of television to revive literature. Despite the odds against her--selecting hard-to-read, quirky books by generally unknown authors--Winfrey has successfully created women's spaces for the 1990s, not so different from the American women's social clubs from the late 1800s and early 1900s, and the French salons of the sixteenth and seventeenth centuries. This study will show how Oprah's Book Club allows readers, especially women, to use the psychological processes of transference and transactional reading by using fictional literature from the Book Club to discuss sensitive areas of their lives.

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 ...
