Organização do trabalho doméstico em casais do mesmo sexo

Em resposta ao predomínio da heteronormatividade nos estudos sobre o trabalho doméstico, este artigo explora a forma como este é organizado e distribuído em casais do mesmo sexo. Para esse efeito, desenvolveu-se uma pesquisa qualitativa (20 entrevistas aos membros de casais homossexuais) em torno dos desequilíbrios, do processo de negociação, do nível de satisfação, e ainda da herança familiar genderizada na actual organização do trabalho doméstico. Concluiu-se que a ausência da diferença de sexo no casal contribui para uma mais flexível e paritária negociação da organização das tarefas. Reflexo da socialização de género, as mulheres tendem para uma maior especialização e os homens para uma maior delegação das tarefas. In response to the predominance of heteronormativity in the studies on the household labour, this article explores the way it is organized and distributed in same-sex couples. Qualitative research was carried out on the basis of 20 interviews with members of homosexual couples, and informationwas collected on the imbalances, negotiation, satisfaction and gendered family legacy in the current organization of household labour. Results show that the absence of the sex difference between the members of the couple contributes to more flexible and egalitarian negotiation in the organization of chores. As a consequence of gender socialization, women tend to specialize and men to delegate.

Particle agglomeration study in rf silane plasmas: In situ study by polarization-sensitive laser light scattering

To determine self-consistently the time evolution of particle size and their number density in situ multi-angle polarization-sensitive laser light scattering was used. Cross-polarization intensities (incident and scattered light intensities with opposite polarization) measured at 135 degrees and ex situ transmission electronic microscopy analysis demonstrate the existence of nonspherical agglomerates during the early phase of agglomeration. Later in the particle time development both techniques reveal spherical particles again. The presence of strong cross-polarization intensities is accompanied by low-frequency instabilities detected on the scattered light intensities and plasma emission. It is found that the particle radius and particle number density during the agglomeration phase can be well described by the Brownian free molecule coagulation model. Application of this neutral particle coagulation model is justified by calculation of the particle charge whereby it is shown that particles of a few tens of nanometer can be considered as neutral under our experimental conditions. The measured particle dispersion can be well described by a Brownian free molecule coagulation model including a log-normal particle size distribution. (C) 1996 American Institute of Physics.
