Fifty-three basins with area less than 9.40 km² were mapped from 1:25,000-scale aerial photographs to provide data on basin morphometry. A significantly larger number of first-order streams exist than are expected according to the regression of stream number on order for each basin. This is attributed to the incorporation of recently formed gullies into the stream network as first-order streams. Most drainage density (Dd) values are in the coarse texture category (Dd<5.0 km/km²). Higher values of Dd correspond to areas of shallow soils. Total stream frequency (F[subscribe t]) and first-order stream frequency (F₁) are closely correlated with Dd (r=+0.86 and r=+0.89, respectively), but third-order stream frequency (F₃) is not (r=+0.70). F[subscribe t] is related to Dd as follows: F[subscribe t]=0.704 (Dd)²̇⁰⁸. Values of ruggedness number (HDd) and basin magnitude indicate that all basins are high-flood potential basins. This imposes serious limitations on the development of the watershed as a whole. Weighted mean percent silt-clay (M) and channel width-depth ratio (F) for 21 cross sections of stream channels were used to define cross section stability. Catchment area above each cross section is related to its stability. As area increases cross sections change from degrading to aggrading to stable conditions. There is a more gradual increase in F with decreasing M than in streams in the mid-western United States. This is attributed to the vigorous vegetation which stabilizes channel banks in the Mandaguari watershed. Recent climatic changes in the region rendered colluvial deposits susceptible to increased erosion under the present subtropical (Cwa) climate. When saturated, the latosols and podzols there are easily eroded owing to their low cohesion (PI=0-15). Recent deforestation and seasonal burning of pastures probably exacerbate this condition, contributing to the erosion of hillsides and the formation of gullies. Large, aggressive gullies (voçorocas) 10-15 m deep and 30-40 m wide occur in association with urban centers. Management of the Riberão do Mandaguari watershed should be based on considerations of (1) threshold conditions for instability of stream channel cross sections and soils and (2) complex responses of the watershed. Recommended actions are reforestation of slopes at and above the point of maximum profile steepness, induced incision of channel filling deposits, and control of runoff from urban centers. / text

During the different stages of this development, we observed a progressive degeneration of the worker's condition in their job so as in their everyday lifea These people were expelled to the suburb areas due to a precarious residencial and urbane situation. Thus, this is a reflection uppon violence and the actual situation in this context, trying to find a new meaning to the City based on this reality / O presente estudo pretende colocar em evidência o processo histórico que leva a um padrão periférico de crescimento urbano na cidade de São Paulo, característico dos processos de urbanização subdesenvolvidos, segregando a população para localizações cada vez mais distantes dos centros do mercado de trabalho, em assentamentos geralmente precários. Assim, desde os anos 40, por diversos mecanismos e razões históricas, diferentes segmentos sociais são envolvidos por essa dinâmica, sendo impelidos em direção a formas cada vez mais precárias de moradia, infraestrutura urbana e de acesso aos serviços e equipamentos públicos, possibilitando muitas vezes a posse da moradia e a fuga do aluguel, mas configurando, de qualquer modo, processos de segregação socioespacial que intensificam a exclusão social e do mercado de trabalho. Nas últimas décadas, as transformações econômicas e do mercado de trabalho acentuam essa tendência, promovendo, especialmente nos anos 90, uma verdadeira diáspora das classes trabalhadoras, que não conseguem mais se manter nas áreas melhor servidas. Assim, se agudiza ainda mais o processo de periferização, com o adensamento progressivo das áreas de ampliação da fronteira urbana metropolitana, Neste contexto, a partir de suas novas características sociais e demográficas, as periferias se apresentam, no presente, como um objeto de estudo relevante, com características urbanísticas e sociais singulares, que redefinem sua importância na problematização do estatuto urbano da cidade de São Paulo e das condições sociais de vida desses segmentos sociais, que são a maioria da população. O presente estudo busca resgatar a especificidade das periferias, incluindo estudos recentes desenvolvidos no âmbito do Projeto Bairro Legal, desenvolvido pela Secretaria de Habitação e Desenvolvimento Urbano do Município de São Paulo, acrescido de reflexões, entrevistas e dados de outras fontes, enfatizando três distritos considerados de alta exclusão social (Jardim Ângela, Brasilândia e Cidade Tiradentes), os quais representam emblemáticas expressões territorializadas e tipologias, no amplo leque da precariedade urbanística e habitacional. Neste campo, propõe-se, por fim, a problematização da questão da violência, pois, a julgar pelas estatísticas e dados sobre os homicídios — sua manifestação mais aguda e visível — nos distritos de maior exclusão social, ele se apresenta como um aspecto privilegiado de análise. Esta questão é entendida como uma referência privilegiada para ampliar a visibilidade sobre os estratos majoritários da infância e juventude, propondo-se a desestigmatização da relação entre pobreza, juventude e violência e qualificandomais o fenômeno, com vistas à problematização da questão da cidadania e das perspectivas de vida nesses estratos sociais

This is a study of choro in São Paulo, with a brief ethnography of seven-string guitarists. Studies of choro have routinely favored Rio de Janeiro, the birthplace of choro. This work focuses on São Paulo because it has a rich choro tradition, as well as an active and creative contemporary choro scene that has frequently been overshadowed by Rio de Janeiro's. There are three main parts to this study. The first part provides background information, including the major guitarists that have contributed to the development of the guitar's role in choro, and brief reviews of the most important literature on the subject of choro. The second part discusses São Paulo, my methodology, and the music scholars that have informed this study. The second part is the analytical base for the study, in which I examine the song, "Sampa" (1978), by Caetano Veloso, and interpret the uses, functions, and concepts of choro, drawing from Alan Merriam. Part II also includes a brief discussion of the resurgence of choro in the 1970s. This work proposes that choro has as its principal functions both musical and social education. The musical education choro provides is aural, notational, historical, and improvisational. The social education choro provides is one of an idealized mythological "racial democracy." The third and final part is a brief ethnography of the contemporary choro scene in São Paulo, with a focus on seven-string guitarists, and a descriptive account for the contextualization of choro. / text
