This paper presents a non-heterosexual young lady s Narrative Life History. By presenting it, we aim to understanding how desire, (in)visibility and the processes of exclusion are articulated in relation to the experience of homoeroticism, especially within the family. By this, we are able to point out some homophobic aspects, modes of how the device of closet operates and how some expectations and demands exert pressures over a non-heterosexual member in the family. In this case study, the way her family lived her sexuality depended on a strong family ties, such as: the secret about sexuality. Such secret, according to our hypothesis, was produced and preserved by homophobia which served as the major aspect on the construction of gender and (dis)unity of the family. This work is part of a in progress doctoral thesis, sponsored by FAPESP Fundação para o Amparo à Pesquisa no Estado de São Paulo.

Os autores analisaram diferentes fatores que podem influenciar na decisão das mães de amamentar, na duração da amamentação e as principais razões do desmame. Foram selecionados artigos publicados entre 1990 e 2004 das bases de dados Lilacs, Medline, Scielo, Bireme, utilizando as palavras-chave: desmame e fatores de risco, bem como suas versões em inglês. Alguns fatores, como maternidade precoce, baixo nível educacional e socioeconômico maternos, paridade, atenção do profissional de saúde nas consultas de pré-natal, necessidade de trabalhar fora do lar, são freqüentemente considerados como determinantes do desmame precoce. Contudo, outros, como o apoio familiar, condições adequadas no local de trabalho e uma experiência prévia positiva, parecem ser parâmetros favoráveis à decisão materna pela amamentação. Apesar da relevância dos fatores mencionados acima, os aspectos culturais e a história de vida da mãe foram os mais importantes na decisão materna pelo aleitamento e pelo momento do desmame.

The objective of this study was to evaluate the performance of broilers reared under different population densities in the cold and hot seasons of the year. Two identical experiments were conducted, one during the winter for 49 days, and the other during the summer where the chicks were slaughtered at 42 days of age. Commercial Hubbard broiler-type chicks were distributed in a randomized block design in a 4 × 2 factorial arrangement with population densities of 10, 14, 18, and 22 birds/m 2, by sex, and with four replications. Feed intake was reduced with a progressive decrease of available space for the chicks, and it resulted in a linear decrease in weight gain. However, there was a linear increase in the live weight of broilers in kilograms per area of floor space, proportional to the increase of population density, without effect on the viability. The progressive increment in the population density reduced the observed feed/gain ratio during the total winter rearing period for both sexes. There was no effect of population density on this characteristic during the hot season of the year. Population density did not affect the carcass yield of chicks during the summer. However, there was a linear increase on carcass yield with an increase in population density in the winter. The males, at the age slaughtered, had higher weights, feed intakes, and better feed/gain ratios, and lower abdominal fat and higher live weight production in kilograms per floor area than females. However, the viable index for the males was lower. From the results obtained, there was a linear increase in the liveweight of broilers in kilograms per floor area, making it possible to rear broilers under higher population densities, independent of the season of the year, as well as the occurrence of a decrease in feed intake and weight gain of the chicks with a decrease of available space.
