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

Head and neck cancer is currently the fifth most worldwide common cancer and despite advances in conventional therapies, including surgery, radiotherapy and chemotherapy, the survival rate has not changed in the last three decades. In Brazil, estimatives shows 14.120 new cases of oral cavity cancer in 2010, with 3.790 women and 10.330 men. Objectives: To evaluate the clinical and epidemiological parameters in patients with cancer assisted by head and neck surgery service at the University Hospital of northwest region of São Paulo. Casuistic and Methods: Were retrospectively evaluated medical records of 1.351 patients of head and neck surgery service from january 2000 to may 2010. The variables analyzed were: age, gender, skin color, tobacco and alcohol consumption, primary site, staging and histologic type of tumor, treatment, number of deaths and occupational activity of patients assisted by head and neck surgery service. Results: The disease was more frequent in men (79.70%), smokers (75.15%) and etilist (58.25%). The most frequents sites were oral cavity (29.65%) and larynx (24.12%). The most common histological type was squamous cell carcinoma (84.92%) and 29.04% of individuals had as treatment surgical and 14,19 % radiotherapy Conclusions: This cancer type occurs more common in men smokers and etilists. The primary sites more incident for the patients service are oral cavity and larynx. The high rate of patients with stages III and IV indicates a late diagnosis by the treatment centers, which reflects the need for prevention education campaigns for early diagnosis of the disease. / O serviço de cirurgia de cabeça e pescoço atende pacientes com tumores malignos do trato aéreo digestivo superior, de pele e tireóide. O tumor maligno de cabeça e pescoço é atualmente a quinta neoplasia mais comum de todo o mundo e apesar dos avanços em terapias convencionais, incluindo cirurgia, radioterapia e quimioterapia, a taxa de sobrevida não mudou nas ultimas três décadas. No Brasil, as estimativas revelam 14.120 casos novos de câncer de cavidade oral para 2010, sendo que 3.790 em mulheres e 10.330 em homens. Objetivos: Avaliar os parâmetros clínicos e epidemiológicos em pacientes com câncer atendidos no serviço de cirurgia de cabeça e pescoço em um Hospital Universitário da região noroeste do estado de São Paulo. Casuística e Método: Foram avaliados retrospectivamente prontuários médicos de 1.351 pacientes do serviço de cirurgia de cabeça e pescoço no período de janeiro de 2000 a maio de 2010. As variáveis analisadas foram: idade, gênero, cor da pele, hábitos tabagista e etilista, sítio primário, estadiamento, tipo histológico do tumor, tratamento, número de óbitos e atividade ocupacional dos pacientes atendidos no serviço de cirurgia de cabeça e pescoço. Resultados: Esta doença foi mais frequente em homens (79,70%), tabagistas (75,15%) e elitistas (58,25%). Os sítios primários mais freqüentes foram cavidade oral (29,65%) e laringe (24,12%). O carcinoma espinocelular foi o tipo histológico (84,92%) mais comum e 29,04% dos indivíduos tiveram a cirurgia como tratamento e 14,19% radioterapia. Conclusões: Este tipo de neoplasia é mais freqüente em homens tabagistas e etilistas. Os sítios primários mais acometidos nos pacientes do serviço são cavidade oral e laringe. A alta taxa de pacientes com estadios III e IV indica uma procura tardia dos centros de tratamento, o que reflete a necessidade de campanhas de prevenção educativas para o diagnóstico precoce da doença.
