The Apocalypse will be Televised: Representations of the Cold War on Network Television, 1976-1987Underwood, Aubrey 01 August 2011 (has links)
This dissertation examines how the major television networks, in conjunction with the Reagan administration, launched a lingering cloud of nuclear anxiety that helped to revive the Cold War during the 1980s. Placed within a larger political and cultural post-war context, this national preoccupation with a global show-down with the Soviet Union at times both hindered and bolstered Reagan’s image as the archetypal conservative, cowboy President that could free America from its liberal adolescent past now caustically referred to as “the sixties.” This stalwart image of Reagan, created and carefully managed by a number of highly-paid marketing executives, as one of the embodiment of peaceful deterrence, came under attack in the early 1980s when the “liberal” Nuclear Freeze movement showed signs of becoming politically threatening to the staunch conservative pledging to win the Cold War at any cost. And even if the nuclear freeze movement itself was not powerful enough to undergo the Herculean task of removing the President in 1984, the movement was compassionate enough to appeal to a mass audience, especially when framed in narrative form on network television. In the early 1980s, debates over the possibility of nuclear war and other pertinent Cold War related issues became much more democratized in their visibility on the network airwaves. However, the message disseminated from the networks was not placed in an educational framework, nor did these television productions clarify complicated nuclear issues such as nuclear winter theory and proliferation. I argue this renewed network attention on nuclear issues was not placed in an historical framework and likely confused American viewers because it routinely exposed audiences to both fact and fiction, undifferentiated at the level of the mass media.

Manželky českých politiků v 19. století / The women of the bohemian politicians in the 19th centuryBUREŠOVÁ, Jitka January 2008 (has links)
The women of the bohemian politicians in the 19th century Annotation I have chosen ten women of the bohemian politics living in the 19th century. The first chapter has been about the reasons for choice of the life female partner. I have described the social, lingual and religious background of these women. I have tried to analyse their antenuptial correspondence. The second part of my work has attended to the use of women in the social life and it has focused on their involvement into the {\clqq}morning-room`` life. I have outlined the women incidence in the public asociation in the third chapter.I have been interested in any women activites mainly the philanthrophy. I have tried to find out if the husbands had encouraged thein wives in these acitivities. I have focused on the role of women in the family. I have observed how the husbands had been participated in the running the household and education of their children. I have studied the family correspondence. I have focused on the political aspect of the letters. I have tried to catch how much the women had been interested in the policy.

Innovative Tessellation Algorithm for Generating More Uniform Temperature Distribution in the Powder-bed Fusion ProcessMaleki Pour, Ehsan 12 1900 (has links)
Purdue School of Engineering and Technology, Indianapolis / Powder Bed Fusion Additive Manufacturing enables the fabrication of metal parts with complex geometry and elaborates internal features, the simplification of the assembly process, and the reduction of development time. However, the lack of consistent quality hinders its tremendous potential for widespread application in industry. This limits its ability as a viable manufacturing process particularly in the aerospace and medical industries where high quality and repeatability are critical. A variety of defects, which may be initiated during the powder-bed fusion additive manufacturing process, compromise the repeatability, precision, and resulting mechanical properties of the final part. The literature review shows that a non-uniform temperature distribution throughout fabricated layers is a significant source of the majority of thermal defects. Therefore, the work introduces an online thermography methodology to study temperature distribution, thermal evolution, and thermal specifications of the fabricated layers in powder-bed fusion process or any other thermal inherent AM process. This methodology utilizes infrared technique and segmentation image processing to extract the required data about temperature distribution and HAZs of the layer under fabrication. We conducted some primary experiments in the FDM process to leverage the thermography technique and achieve a certain insight to be able to propose a technique to generate a more uniform temperature distribution. These experiments lead to proposing an innovative chessboard scanning strategy called tessellation algorithm, which can generate more uniform temperature distribution and diminish the layer warpage consequently especially throughout the layers with either geometry that is more complex or poses relatively longer dimensions. In the next step, this work develops a new technique in ABAQUS to verify the proposed scanning strategy. This technique simulates temperature distribution throughout a layer printed by chessboard printing patterns in powder-bed fusion process in a fraction of the time taken by current methods in the literature. This technique compares the temperature distribution throughout a designed layer printed by three presented chessboard-scanning patterns, namely, rastering pattern, helical pattern, and tessellation pattern. The results confirm that the tessellation pattern generates more uniform temperature distribution compared with the other two patterns. Further research is in progress to leverage the thermography methodology to verify the simulation technique. It is also pursuing a hybrid closed-loop online monitoring and control methodology, which bases on the introduced tessellation algorithm and online thermography in this work and Artificial Neural Networking (ANN) to generate the most possible uniform temperature distribution within a safe temperature range layer-by-layer.
