Episodes at the End of Landscape: Hudson River School to American Modernism

Cao, Maggie M. January 2014 (has links)
This dissertation examines the dissolution of landscape painting as a major cultural project in the late nineteenth-century United States. As a genre aligned with the goals of nation building, landscape maintained a privileged artistic status for much of the nineteenth century. Yet as frontier development, land speculation, environmental change, and other factors slowly rendered its conventions meaningless, landscape became the site through which American artists most urgently sought to come to terms with the modern world. This argument is anchored by unorthodox artworks, from landscapes resembling banknotes to paintings made out of bird feathers—limit cases that allude to the failure of landscape in sustaining American cultural goals. Chapter One concerns Albert Bierstadt's aesthetic struggles in post-frontier America. During the 1890s, Bierstadt's anxieties about landscape surfaced in the particularities of objects that fold and unfold, from butterflies painted by chance to expanding railway cars—objects that might be considered the subconscious of a genre built upon expansionist ideology. Chapter Two argues that Martin Johnson Heade's tropical and marsh paintings of the 1870s and 1880s used “groundless” conditions to express cultural insecurities about traversable land and its representation. The pictorial blockages and interferences in Heade's paintings challenge both the compositional legibility espoused in the blockbuster canvases of his mentor and rival Frederic Church and the physical accessibility promised by the period's environmental interventions. Chapter Three proposes that Ralph Blakelock's nocturnes and money paintings—produced in the context of rampant land speculation, volatile art markets, and representational doubts surrounding paper currency—attempt but fail to overcome landscape's monetary entanglements. Blakelock's paintings theorize the value of labor and material accumulation in the increasingly abstract economic world of the last decades of the nineteenth century. Chapter Four reconsiders the trope of the "figure in the landscape" using Abbott Thayer's turn-of-the-century representations of animal camouflage. In these mixed-media artworks, Thayer's attempts to visualize invisibility demonstrate the ways in which camouflage proved irreconcilable with landscape's figure-ground principles. Together, these episodes trace pictorial attempts to resolve spatial problems arising with modernity, and in so doing, they signal a shift toward new paradigms of representation. / History of Art and Architecture

A structure by no means complete : a comparison of the path and processes surrounding successful passage of Medicare and Medicaid under Lyndon Baines Johnson and the failure to pass national health care reform under William Jefferson Clinton

Johnson, David Howard 25 January 2011 (has links)
In this comparative policy development analysis, I utilize path-dependence theory and presidential records to analyze President Lyndon Johnson's success in passing Medicare and Medicaid and President Bill Clinton's failure to pass national health care reform. Findings support four major themes from the Johnson administration: 1) President Johnson had a keen understanding of the importance of language in framing debate; 2) He placed control of the legislative process in the hands of a small, select group of seasoned political operatives and career policymaking professionals; 3) He paid considerable attention to the details of negotiations and the policy consequences; and 4) He had a highly developed sense of the political and legislative processes involved in passing major legislation. The case study of the Clinton administration reveals five major themes: 1) There is a lack of evidence that President Clinton remained actively engaged throughout the policy development and legislative processes, instead choosing to delegate the process to the First Lady; 2) There was a naiveté on the part of the Clintons and many administration staff members with regard to the legal and political ramifications of their decisions; 3) The Clintons tried to make the plan fully their own, sharing little credit for its development with Congress; 4) Their attempts to incorporate existing corporate health care delivery structures with their vision for universal coverage proved unworkable; and 5) The extended time from task force launch to bill delivery gave opponents ample time to marshal their opposition forces. I conclude that in developing health care legislation, Johnson had the advantages of: 1) a small group of key policymakers; 2) multiple, simultaneous legislative initiatives which diffused the attention of a more limited media; and, 3) national crises which promoted an environment conducive to sweeping policy change. I suggest that major, national health care reform will not occur until: 1) an economic or geopolitical crisis sets the stage for change; 2) business interests and progressive interests find common ground; and, 3) Americans achieve a new cultural understanding of universal health care as both economically just and economically necessary. / text

Modelling of failure

Björklund, Oscar January 2008 (has links)
This report is a review of some failure models today used for determine failure in thin sheets of high strength steels. Focus has been given on phenomenlogical models and only some simple simulations have been carried out. The phenomenlogical models that have been summarized here are of four different categories, namely stress based, strain based, combined stress and strain based and damaged models. However, the simulations have only been preformed for some of the models.

Norm-referenced cognitive and achievement scores as predictors of state-wide high-stakes test scores with students referred for special education / High-stakes testing

Trinkle, James M., II 20 July 2013 (has links)
Relatively recent federal education initiatives, such as No Child Left Behind (NCLB; 2001), have focused on school accountability for student achievement including achievement of traditionally at-risk populations, such as students in special education, students from low-income or high poverty areas, and students who speak English as a new second language. Additionally, these federal initiatives also mandate that all students take the same test measuring grade level standards despite research that has demonstrated that students from at-risk populations are sometimes at a disadvantage on high-stakes tests. Furthermore, initiatives such as NCLB are often at odds with other education initiatives such as IDEA, which states that students in special education should be tested at their respective level. Therefore, the current study proposed to examine the relationship between Cattell-Horn-Carroll cognitive abilities and performance on a state-wide high-stakes achievement test. There currently are no studies examining such a relationship. This study used Multivariate Regression Analysis, in order to investigate the relationship between CHC cognitive and achievement abilities and performance on a state-wide high-stakes achievement test, namely the ISTEP+, with 45 children who had been referred for a psychoeducational evaluation to determine special education eligibility and who had also taken the ISTEP+. No statistically significant result was found between the WJ-III-COG broad CHC abilities and performance on the English/Language Arts and Math performance of the ISTEP+. Furthermore, no statistically significant result was found between the WJ-III-ACH and Math performance on the ISTEP+. However, a statistically significant result was found between the WJ-III-ACH Passage Comprehension subtest and the English/Language Arts portion of the ISTEP+. The results indicated that students who had higher scores on the Passage Comprehension subtest also had higher scores on the English/Language Arts portion of the ISTEP+. The current study took a step forward in the area of the relationship between CHC and academic achievement, particularly state-mandated high-stakes testing given the dearth of research in this area. Given the data from the current study indicating a statistically significant relationship between Passage Comprehension and English/Language Arts from the ISTEP+, the current study has practical implications for school psychologists, especially when school psychologists are being asked to make predictions regarding a student’s academic achievement. Results of the current study might help elucidate reading problems and recommended interventions for those reading problems. / Department of Educational Psychology

Exhibitions As The Medium Of Architectural Reproduction &quot / modern Architecture: International Exhibition&quot

Tabibi, Baharak 01 April 2005 (has links) (PDF)
This thesis studies the influential role of architectural exhibitions in shaping and directing architectural discourses. The study accepts architectural exhibitions and associated publications as the critical act of architecture, in which (the work of) architecture is interpreted, reproduced and publicized. The main focus of this thesis is Modern Architecture: International Exhibition, held in 1932 at the Museum of Modern Art (MoMA). This particular exhibition is a significant historical event, which officially announced architecture of the early 20th century as International Style. The thesis underlines the role of the 1932 exhibition and MoMA as an architectural media in reproducing the works of architecture and reformulating the agenda of 20th century modern architecture especially in U.S.A.

Estudo da fratura em solda ponto por fricção em alumínio Alclad 2024-T351 e alumínio 2024-T351 : uma abordagem numérica experimental

Brzostek, Robson Cristiano January 2012 (has links)
Friction Spot Welding (FSpW) é um processo de solda ponto por fricção, que opera na fase sólida do material e permite unir duas ou mais chapas de metal sobrepostas. Além de ser bastante usado para soldar materiais leves, ele também é aplicável a qualquer material que apresente boa plasticidade. Neste trabalho são analisados dois materiais: AA Alclad 2024-T351 e AA 2024-T351, diferindo entre si no uso, ou não, da camada de proteção contra a corrosão (Alclad). As uniões são feitas sob os mesmos parâmetros do processo, previamente estudados para o material com Alclad. Dois parâmetros são utilizados: um dito ótimo, capaz de produzir soldas com bom desempenho mecânico e reprodutibilidade e um segundo, dito insuficiente, por produzir soldas de baixo desempenho mecânico e baixa reprodutibilidade. Pretende-se, com este trabalho, avaliar os efeitos que a camada Alclad pode acarretar nas juntas soldadas, em seu desempenho mecânico, no modo de fratura, na microestrutura e na geometria da junta. Os resultados apresentam uma grande influência do Alclad, tendo em vista que durante o processo o recobrimento migra das superfícies das chapas para o centro da solda. Assim, uma interface deste material, que possui baixa resistência mecânica, é criada, influenciando negativamente o desempenho da junta e alterando o modo de fratura. O principal escopo desta dissertação é realizar uma análise da fratura do ensaio de cisalhamento, com o uso do método de elementos finitos. Portanto, fazse necessário estudar e desenvolver um modelo numérico capaz de representar a nucleação, coalescimento, formação de uma ou mais trincas e a consequente propagação até a fratura do corpo. Para a realização da análise utilizou-se o modelo numérico de fratura Johnson-Cook (JC), o qual expressa a tensão equivalente como uma função da deformação plástica, da taxa de deformação e da temperatura. Realizou-se, ainda, um estudo acerca das teorias do Continuum Damage Mechanics (CDM), bem como se fez necessário obter novos parâmetros para o modelo, que descrevessem o fenômeno e o material. Nesse sentido, serão realizadas duas análises, sendo que a primeira considera o efeito da camada de Alclad e, a segunda, considera uma solda livre de defeitos. Espera-se identificar os locais em que trinca é nucleada e analisar a resposta da junta, passo a passo, durante a propagação da trinca, até a fratura completa do corpo. E, por fim, avaliar a interferência no modelo numérico da presença da camada contra a corrosão Alclad. / Friction Spot Welding (FSpW) is a friction spot weld process, it operates in the solid-state of the material and allows joining two or more sheets in overlap configuration. It is used to join light weight materials, also is suitable to any material that shows good ductility. In this work two different materials are analyzed AA Alclad 2024-T351 e AA 2024-T351, between them the use, or not, of the corrosion protection layer Alclad. The welds are made under the same process parameters previously studied to the material with Alclad. Two parameters are utilized: the first one is the optimum parameter capable to produce welds with good mechanical performance and reproducibility, and another one inadequate because it produces joins with poor mechanical response and reproducibility. It is intended with this work, to evaluate the effects that the Alclad layer can cause in the welds, in its mechanical performance, fracture mode, microstructure and geometry of the join. The results showed a considerable influence of the Alclad, considering that during the process, it migrates from the sheet surface to the center of the weld. Thus, an interface of this material, that has a very low hardness, is created, influencing negatively the performance of the weld and changing the fracture mode. The aim of this dissertation is to perform an analysis of the fracture from the lap shear test, using the finite element method. Therefore, becomes necessary study and develop a numerical model capable to represent the nucleation, coalescence, formation of one or more cracks and, the consequent propagation until the fracture of the body. To perform the analysis it was used the numerical model of fracture called Johnson-Cook (JC), which expresses the equivalent stress as a function of the plastic deformation, the strain rate and the temperature. It was also made a study about the Continuum Damage Mechanics (CDM) theories, and it was necessary to obtain new parameters for the model, that describe the phenomenon and the material. In this sense, it will be performed two analyses, and the first considers the Alclad layer and, the second, considers a weld without defects. It is expected to identify the places where the crack nucleated, and analyze the behavior of the weld, step by step, during the crack propagation, until the complete fracture of the component. And, finally, evaluate the interference in the numerical model of the presence of the protection corrosion layer Alclad.

The issue (the reassessment of the doctrine of the units) consists in the defense that Johnson does in favor of Shakespeare's plays against the censures of other neoclassical critics, these influenced by French classicism. The defense that English critic undertook in favor of the English poet‘s dramas against the reproaches of neoclassical critics anticipated the rupture of the English criticism with the classical aesthetic. The proposal is treating of the literary and philosophical aspects involved in the chief theme, at last to amplify the horizon of reading through of the notions of structure of feeling by Raymond Williams (1977) and political unconscious by Jameson (1992). / O objetivo desta dissertação é demonstrar, por meio de uma leitura dialética do Preface to Shakespeare (1765) de Samuel Johnson (1709-1784), que a reavaliação das doutrinas das unidades (ação, tempo e lugar) não revela somente a ruptura da crítica literária inglesa com a estética clássica, mas o prenúncio de uma ruptura profunda da sociedade capitalista inglesa do século XVIII com o Ancien Régime. A seguinte questão (a reavaliação da doutrina das unidades) consiste na defesa que Johnson faz a favor das peças de Shakespeare, contra as censuras de outros críticos neoclássicos, estes influenciados pelo Classicismo francês. A defesa que Johnson empreende a favor dos dramas do poeta inglês, contra a acusação dos críticos neoclássicos, antecipa a ruptura da crítica inglesa com a estética clássica. A proposta é tratar dos aspectos literários e filosóficos envolvidos no tema principal, e por fim, ampliar o horizonte de leitura, através dos conceitos de structure of feeling de Raymond Williams (1977) e inconsciente político de Jameson (1992).
