Cet article porte sur les conditions de production d'un savoir articulant féminisme et pluralisme culturel, à partir de l'expérience de recherche des auteures menée sur les stratégies de reconstruction identitaire de femmes immigrantes en régions et dans laquelle ont été impliquées des chercheuses, des intervieweuses et des participantes. Tout en exposant les principes et stratégies issus de l'approche féministe et du courant interculturel qui ont guidé leurs choix méthodologiques, les auteures analysent les difficultés et les zones d'incertitude qui se posent aux chercheuses féministes dans la production d'un savoir articulant femmes et cultures. Elles privilégient comme «analyseur» de ce processus l'ensemble des interactions qui se sont produites dans et entre les trois groupes en scène dans leur recherche : celui des chercheuses, celui des intervieweuses et celui des participantes- informatrices.This article deals with the conditions of production of an area of knowledge linking feminism to cultural pluralism. It is based on a study of immigrant women identity strategies in the Sherbrooke area, an experience which involved women as researchers, interviewers, and participant-subjects. The article explains the principles and strategies of the feminist approach and the intercultural current which informed methodological choices. It also analyzes the difficulties and uncertainties which confront researchers engaged in the production of knowledge linking women and culture. The authors emphasize, as the "analyzer" of this process, the entire range of interactions produced within and between the three groups of women in the study

The Masking Level Difference (MLD) test is one of the main instruments for investigating binaural interaction. Studies with children aged 7–12 years still disagree about the influence of age on test performance and present discordant reference values. This study aimed to verify the effect of age on the performance of children aged 7–12 years in the MLD test and to establish reference values and cutoff criteria for this age group. Fifty-nine children with normal hearing were organized in three groups according to their age: 7–8 (n = 20), 9–10 (n = 20), and 11–12 (n = 19) years. The participants completed the MLD test by Auditec®. The Kruskal–Wallis statistical test was used to compare groups. Reference values were obtained by calculating mean, standard deviation, median, mode, and percentiles, while the cutoff criterion was obtained by subtracting two standard deviations from the mean. No statistically significant differences were observed between the groups regarding the MLD test measures. The mean MLD was 10.51 ± 1.84 dB and the cutoff point was set at 7 dB. Thus, reference values for the MLD test were established for children aged 7–12 years, who presented no effect of age on test performance.

A bioprospecção de micro-organismos que possam ser utilizados na biorremediação de ecossistemas degradados é o primeiro passo nas pesquisas que visam utilizar a atividade microbiana para converter substâncias tóxicas em compostos menos nocivos. A Baía de Guanabara, no Sudeste do Brasil, constitui um bioma com grande quantidade e diversidade de poluentes lançados em suas águas, o que compromete a saúde ambiental de tal ecossistema. O presente estudo teve como objetivo avaliar o potencial de biorremediação de bactérias isoladas das praias da Baía de Guanabara. Os micro-organismos foram isolados, identificados, guardados em coleção de cultura e investigados em pesquisas biotecnológicas de biorremediação, quanto à resistência aos metais mercúrio e cromo. Foi avaliada a presença de genes envolvidos nos processos de biorremediação, sendo eles os genes merA, ChrA e ChrB. Dos 169 micro-organismos testados, 8,8% apresentaram resistência ao mercúrio de até 3 mg/L e, em dois isolados, detectou-se a presença do gene merA. Um total de 25,2% dos micro-organismos apresentou resistência ao cromo de até 1 μg/L. Contudo, em nenhum isolado houve presença dos genes ChrA e ChrB nas condições utilizadas.
