The main purpose of this study was to provide an estimate for the onset of morphological sexual maturity in the freshwater crab Trichodactylus fluviatilis, from a population located in south-eastern Brazil, based on the relative growth relationships, as well as the characterization of ''handedness''. Monthly collections were carried out at night, from January 2006 to January 2007, in a small water body. In the laboratory, the crabs were sexed; the following body structures were measured and the estimate of onset of sexual maturity was given by the logistic function, as y a/(1\+becx), for 50% of the population to reach the adult phase (CW50carapace width). Right propodus length and abdomen width were the best-fit relationships to represent the onset of sexual maturity for males and females, respectively. Based on the logistic function, the onset of sexual maturity was estimated to occur at around 18mm CW for both sexes. The relative growth recorded for this species is consistent with the model for brachyuran crabs (Hartnoll RG. 1982, Growth. In: Bliss, DE, editor. The biology of Crustacea: embryology, morphology and genetics. New York: Academic Press. p. 111-196), except for the abdomen growth, which is likely to be an adaptive condition related to protection of the newly hatched young. © 2013 Taylor & Francis.

Este estudo teve como contexto uma escola ribeirinha no município de Breves, situado na Ilha do Marajó, no Estado do Pará. Objetivo mestre: Analisar as representações sociais de jovens-alunos do ensino fundamental da Escola Municipal de Ensino Fundamental São Francisco, da Comunidade São Francisco, no município de Breves sobre exploração sexual nas balsas do Marajó e as implicações nas suas vidas escolares. Objetivos condutores: Identificar o perfil dos alunos-jovens; Verificar as imagens e os significados destes alunos-jovens sobre a exploração sexual juvenil; Destacar as objetivações e as ancoragens como elementos que compõem as Representações Sociais de alunos-jovens e alunas-jovens sobre a exploração sexual juvenil; Relacionar as Representações Sociais de alunos e alunas jovens sobre a exploração sexual juvenil nas balsas do Marajó e as implicações nas suas vidas escolares. Participaram deste estudo 16 jovens, na faixa etária entre 14 e 20 anos, matriculados entre a 4ª e 6ª série do ensino fundamental. Tratou-se de uma pesquisa qualitativa-descritiva. O referencial teórico foi a Teoria das Representações Sociais – TRS, com base em Moscovici (2010) e Nascimento (2002). A análise de dados se deu a partir dos referenciais metodológicos de Franco (2008) e Nascimento e Moraes (2010); As Representações Sociais dos jovens-alunos sobre a exploração sexual juvenil nas balsas do Marajó constituíram-se no Rio de possibilidades, cuja imagem se apresenta pelo encantamento, e Rio que traga, imagem representada pelo desencantamento. Além destas RS, destacaram-se significações cuja imagem foi o sentimento de culpa, que se destaca como significado de ser julgado pela comunidade, ter a atribuição de balseira, medo de sofrer ameaças e pelo sentimento de ausência do poder público. A partir destas significações, ressaltamos enquanto ponto de ancoragem o silêncio. Este sentimento que não se pode ouvir brada de sentidos, ora pelo medo de sofrer alguma espécie de julgamento social ora pelo sentimento de esvaziamento que esta condição da exploração sexual se materializa em suas vivências. As implicações escolares constituídas a partir das Representações Sociais de jovens-alunos sobre a exploração sexual juvenil foram: fragilização na formação escolar e no processo psicossocial de desenvolvimento juvenil; falta de aprendizagem; desatenção nos conteúdos e atividades escolares; desinteresse pela escolarização (Abandono escolar e Repetência escolar). Estes elementos e as análises teóricas articuladas a partir dessas Representações Sociais nos apontam como conclusão que a exploração sexual nos rios e furos da paisagem amazônica ainda é pouco visível, uma vez que as ações do poder público ainda não dão o lugar para este fenômeno no sentido de seu combate e enfrentamento. Entendemos, portanto, que deve haver uma ação educativa que possibilite o enfrentamento da exploração sexual juvenil.

OBJECTIVE:The present study aimed at estimating the prevalence of lifetime sexual abuse among women and at investigating its association with alcohol consumption.METHOD:Population-based survey conducted through a representative and stratified cluster sample of metropolitan São Paulo. GENACIS questionnaire was used. Sample unit was the home, and all residents aged 18 years and over were interviewed. The outcome was lifetime sexual abuse. The univariate statistical analysis used the Rao-Scott test. Logistic regression was used for the multivariate analysis.RESULTS:The final sample totalized 1,216 women aged 18 years and over; the response rate was 75.0%. Most women were married (56.6%) and had less than 12 years of formal education (59.0%); 46.2% were aged between 25 and 44 years, and 44.4% had a low income. Of the respondents, 7.5% reported having suffered lifetime sexual abuse. Multiple logistic regression model showed an association between lifetime sexual abuse and being a heavy drinker (OR = 4.97) and being a former drinker (OR = 2.04).CONCLUSIONS:There are few population studies in Brazil investigating sexual abuse and its relation to alcohol use. Although the prevalence of lifetime sexual abuse in the present study was smaller than that observed in other studies, it is a highly expressive percentage on account of its social and economic impact, as well as its potential effect on the health system.

The aim of the present study was to determine the size at sexual maturity in the freshwater crab Dilocarcinus pagei Stimpson, 1861, from a population located in Mendonça, state of São Paulo, Brazil. The crabs were sampled monthly (July 2005 to June 2007), at Barra Mansa reservoir. The specimens were captured manually or in sieves passed through the aquatic vegetation. The crabs were captured and separated by sex based on morphology of the pleon and on the number of pleopods. The following dimensions were measured: carapace width (CW); carapace length (CL); propodus length (PL); and abdomen width (AW). The morphological analysis of the gonads was used to identify and categorize individuals according to their stage of development. The morphological maturity was estimated based on the analysis of relative growth based on the allometric equation y = ax b. The gonadal maturity was based on the morphology of the gonads by the method CW50 which indicates the size at which 50% of the individuals in the population showed gonads morphologically mature to reproduction. The biometric relationships that best demonstrated the different patterns of growth for the juvenile and adult stages were CW vs. PL for males and CW vs. AW for females (p<0.001). Based on these relationships, the estimated value to morphological sexual maturity was 21.5 mm (CW) in males and 19.7 mm (CW) in females. The determination of the size at sexual maturity and the adjustment of the data based on the logistic curve (CW50) resulted in a size of 38.2 mm for males and 39.4 mm for females (CW). Based on the data obtained for sexual maturity for D. pagei, we can estimate a minimum size for capture of 40 mm (CW). This minimum size allows at least half of the population to reproduce and retains the juveniles and a portion of the adults in the population.
The modern math movement(s): an essay on how elementary school teachers in Brazil gave meaning to it
Resumo:
The main goal of this paper is to discuss the production of meaning of the Modern Math Movement. The main sources were data available in school archives and interviews with former teachers that we use in order to focus on the diversity of perspectives -that complement it or oppose it-, which comes up when teachers refer to the Movement. Using this process of signification, teachers whether accept it, invalidate it or adapt it to guidelines imposed to them in their teaching activities. We establish a methodology by following the premises of Oral History to gather oral testimonies. The theoretical foundations in which this article is written are the guidelines of Paul Ricoeur's Hermeneutics, John Thompson's Depth Hermeneutics and Bolivar's narrative analysis.
