The present dissertation on autism spectrum disorders (ASD) addressed several questions. First, the behavioral symptoms of speaking and mute individuals with ASD were compared on the Autism Behavior Checklist (ABC), a commonly used diagnostic instrument. In addition, questions about the construction of the ABC were investigated. In Study I it was found that although the two groups did not significantly differ on the total ABC score, the mute group demonstrated significantly more pathology on 21 of 57 items and 3 of 5 subscales. The speaking group obtained significantly higher scores on only 8 items and 1 subscale (Language). The appropriateness of providing greater pathology scores to speaking, rather than mute, individuals with ASD was called into question. In addition, it was speculated that the expressive language items are weighted too heavily, on both the Language subscale and the total score. Second, because the 57 items of the ABC were categorized into 5 subscales on a subjective basis, an empirical investigation of the factor structure of the ABC was performed. In Study II, a 5-factor model that contained 39 of the items accounted for 80% of the total variance in the checklist. No support was found for classifying the 57 items into the existing 5 subscales. Finally, the two most common forms of instruction to teach children with ASD, discrete-trial teaching and incidental teaching, were assessed. In Study III it was ascertained that discrete-trial teaching was more efficient and produced faster acquisition and initially, greater generalization. However, by follow-up, the incidental teaching methods resulted in equal retention, greater generalization, and equal or greater spontaneous usage. The findings indicate that although it takes a longer time for children with autism to learn with incidental teaching procedures, once they have acquired an ability, it may be more permanent.

O presente trabalho tem como objetivo analisar a concepção, formalização e ocupação da Marquise do Parque Ibirapuera, através de uma trajetória que se inicia com a definição do programa de necessidades para as comemorações do IV Centenário da cidade de São Paulo, na década de 50 do século passado. Onde foi tomada a decisão de realizar a construção do que seria o maior parque público da cidade, somado a um conjunto edificado que centralizaria a maioria das atividades propostas durante o período de festividades. Ao mesmo tempo que essa grande obra deveria mostrar a força do progresso do Estado, serviria de legado as próximas gerações. Assim, a construção do programa funcional e sua posterior concepção arquitetônica, de autoria de Oscar Niemeyer e equipe, se mostram fundamentais como fonte de análise para entender o surgimento do elemento de ligação, a grande marquise, entre os pavilhões temáticos propostos. A primeira parte do trabalho examina a evolução do projeto, seus precedentes e as adversidades enfrentadas durante o período de construção. A segunda parte diz respeito a observação e coleta de dados das atividades realizadas sob esta grande cobertura após a conclusão de sua construção. Demonstrando, através de uma amostragem significativa, sua capacidade de servir de suporte a inúmeros usos, sejam eles programados ou espontâneos, no decorrer dos ultimos 60 anos. Superando seu programa inicial de ligação e suporte aos pavilhões com que está conectado e se consolidando como um lugar de intenso convívio social e de encontros, aberto a imprevisibilidade, ao uso indeterminado. / This study aims to analyze the design, formalization and occupation of the Ibirapuera Park\'s Great Marquee, through a trajectory that begins with the definition of the architectural brief for the IV Centennial of the city of São Paulo celebrations in the 1950\'s. Then was the decision to undertake the construction of what would be the largest public park in the city, plus a built set centralizing most of the proposed activities during the festivities. At lhe same time this great work should show the strength of the State\'s progress, it would serve as a legacy to future generations. Thus, the construction of functional program and subsequent architectural design of Oscar Niemeyer and team, show up as a source of fundamental analysis to understand the emergence of the connecting element, a large marquee, between the proposed thematic pavilions. Showing the evolution of the design, its precedents and adversities during the construction period. Conforming the first part of this work. The second part of the work is concerned with the observation and data collection of the activities performed under this great cover upon completion of its construction. Demonstrating, through a significant sample size, its architectural ability to provide support to a number of uses, whether preprogrammed or spontaneous, over the last 60 years. Overcoming its initial briefing as a connection and support to the pavilions, it consolidates itself as a place of intense social life and meeting, open to unpredictability, to the indefinite use.
