"The paper explores the mediating role of [the] property market in generating residential segregation [in the city of Rio de Janeiro, Brazil].... It is shown that the market for apartments is still basically high-income oriented (in contrast with the situation in cities of the developed countries) and that the rapid (faster than family mobility) spatial deconcentration of this market...has played an important role in expelling...the poor, albeit through indirect means, from the areas subjected more intensively to new property developments."

"The paper evaluates the Brazilian system of demographic information and analyses the available sources...and their utilization in published papers. The author has also done a survey asking [participants] about the utilization of this information. [The author concludes] that the information is underutilized." (SUMMARY IN ENG), (excerpt)

"This paper outlines an analysis of intra-urban demography in Sao Paulo [Brazil], by means of differentials among rates of population growth, densities and age distributions of the several spatial segments of the city. In trying to analyze together housing and demographic variables, it associates the youth of the peripheral population to the housing model prevalent till the eighties--irregular allotment, self-help and home ownership. The data show changes in this peripheral pattern for the last decade: the population growth rate of the central zone (mainly the interior ring) has been greater than that of the periphery. This would be explained by the increase of inner city slums and by verticalization. This tendency was already visible from census data of 1970 and 1980, which show an increase in the number of slums and in the proportion of tenants." (SUMMARY IN ENG), (excerpt)

"This paper discusses the range and limits of some concepts of the family, related to theoretical perspectives and to possibilities of an empirical approach to this social group. It argues that in recent studies of the family one can find the symbolic outlook of anthropology on the one hand, which deepens the analysis of dynamics of family relationships, but is limited to strict segments of society. On the other hand, one can find demography and sociology surveys, capable of framing broad portraits which, although liable to generalization, are static and limited to family relations within the household. As an example of possible methodology, the paper describes the proceedings and results of [a study on] family structure and daily life in the city of Sao Paulo [Brazil], in which the author assembles some of the commented approaches, trying to overcome their limitations."

"This paper presents the results of...fieldwork research relating to three Indian societies in Brazil, through the use of the model for the comparative study of fertility proposed by Kingsley Davis and Judith Blake. The collected data show changes within these societies which favourably affected fertility. From this evidence many other questions concerning the social organization and its influence on fertility are discussed." (SUMMARY IN ENG), (excerpt)

"The paper shows at first that using the method of moments to estimate the parameters of a Beta function to fit age specific fertility rates is inadequate. A solution by means of the least squares method is proposed, under the constraint that the implied Total Fertility Rate should equal the observed value." This "iterative solution by means of the Newton-Raphson method turns out to be extremely efficient, converging in only a few steps. In addition, some characteristics of the Beta distribution related to the problem are obtained. The results, applied to 1980 data from the State of Sao Paulo [Brazil], clearly show a better global fit, especially in the area around the peak of the fertility curve." (summary in ENG), (excerpt)
