Psicologia Clínica , 2012, DOI: 10.1590/s0103-56652012000100005
Abstract: O artigo busca esclarecer as dimens es dos chamados direitos sexuais de adolescentes com base em perspectivas empíricas, tanto qualitativas quanto quantitativas. A partir de entrevistas em profundidade e um inquérito domiciliar com jovens sobre conhecimento, experiências e valores associados à sexualidade, o artigo procura demonstrar que a "conversa sobre sexo" é limitada no ambito da família, da escola e nos servi os de saúde. O acesso à informa o e familiaridade com a temática da sexualidade constitui-se em um direito sexual de primeira linha para adolescentes e jovens, a despeito das convic es morais do entorno social. This article focuses on the theme of adolescent sexual rights, based on qualitative and quantitative empirical data. Taking into consideration the results obtained with deep interviews and a population survey with youth about knowledge, experience and values about sexuality, the article shows that "talking about sex" is still limited in different social spheres, that is, family, school and health services. The access to information and approach to sexual themes is a fundamental right to adolescents and youth, despite moral convictions that exist in the social environment.

Abstract: several studies concerning the extra-continental morphological affinities of paleo-indian skeletons, carried out independently in south and north america, have indicated that the americas were first occupied by non-mongoloids that made their way to the new world through the bering strait in ancient times. the first south americans show a clear resemblance to modern south pacific and african populations, while the first north americans seem to be at an unresolved morphological position between modern south pacific and europeans. in none of these analyses the first americans show any resemblance to either northeast asians or modern native americans. so far, these studies have included affirmed and putative early skeletons thought to date between 8,000 and 10,000 years b.p. in this work the extra-continental morphological affinities of a paleo-indian skeleton well dated between 11,000 and 11,500 years b.p. (lapa vermelha iv hominid 1, or "luzia") is investigated, using as comparative samples howells' (1989) world-wide modern series and habgood's (1985) old world late pleistocene fossil hominids. the comparison between lapa vermelha iv hominid 1 and howells' series was based on canonical variate analysis, including 45 size-corrected craniometric variables, while the comparison with fossil hominids was based on principal component analysis, including 16 size-corrected variables. in the first case, lapa vermelha iv hominid 1 exhibited an undisputed morphological affinity firstly with africans and secondly with south pacific populations. in the second comparison, the earliest known american skeleton had its closest similarities with early australians, zhoukoudian upper cave 103, and taforalt 18. the results obtained clearly confirm the idea that the americas were first colonized by a generalized homo sapiens population which inhabited east asia in the late pleistocene, before the definition of the classic mongoloid morphology.
Lapa vermelha IV Hominid 1: morphological affinities of the earliest known American

Abstract: Several studies concerning the extra-continental morphological affinities of Paleo-Indian skeletons, carried out independently in South and North America, have indicated that the Americas were first occupied by non-Mongoloids that made their way to the New World through the Bering Strait in ancient times. The first South Americans show a clear resemblance to modern South Pacific and African populations, while the first North Americans seem to be at an unresolved morphological position between modern South Pacific and Europeans. In none of these analyses the first Americans show any resemblance to either northeast Asians or modern native Americans. So far, these studies have included affirmed and putative early skeletons thought to date between 8,000 and 10,000 years B.P. In this work the extra-continental morphological affinities of a Paleo-Indian skeleton well dated between 11,000 and 11,500 years B.P. (Lapa Vermelha IV Hominid 1, or "Luzia") is investigated, using as comparative samples Howells' (1989) world-wide modern series and Habgood's (1985) Old World Late Pleistocene fossil hominids. The comparison between Lapa Vermelha IV Hominid 1 and Howells' series was based on canonical variate analysis, including 45 size-corrected craniometric variables, while the comparison with fossil hominids was based on principal component analysis, including 16 size-corrected variables. In the first case, Lapa Vermelha IV Hominid 1 exhibited an undisputed morphological affinity firstly with Africans and secondly with South Pacific populations. In the second comparison, the earliest known American skeleton had its closest similarities with early Australians, Zhoukoudian Upper Cave 103, and Taforalt 18. The results obtained clearly confirm the idea that the Americas were first colonized by a generalized Homo sapiens population which inhabited East Asia in the Late Pleistocene, before the definition of the classic Mongoloid morphology.

Abstract: Esta revis o é uma tentativa de produzir uma representa o holística, mas n o exaustiva, dos papéis sexuais femininos no Brasil. Come amos tra ando o papel histórico-político das mulheres do Brasil Colonial até o movimento feminista moderno, enfocando três quest es correntes: planejamento familiar, creches e violência contra a mulher. A seguir, examinamos as normas culturais do machismo e do marianismo. Finalmente, discutimos os avan os que as mulheres fizeram no Brasil na última década (desde a Constitui o de 1988), chamando a aten o para uma quest o que tem sido grandemente ignorada: o assédio sexual.

Revista Brasileira de Psiquiatria , 2002,
Abstract: O processo de envelhecimento promove altera es significativas na produ o e no equilíbrio dos níveis circulantes de diversos horm nios sexuais em homens e mulheres. Acredita-se que esses horm nios (estrógenos, progestógenos, testosterona, dehidroepiandrosterona [DHEA]) exercem papel modulador sobre diversas fun es psíquicas, particularmente sobre o humor e a cogni o. Altera es nesse papel modulador causadas por varia es abruptas dos horm nios sexuais circulantes -- como as que ocorrem, por exemplo, durante a transi o menopausal -- favorecem o surgimento de queixas depressivas. No entanto, a utiliza o terapêutica de horm nios sexuais pode promover alívio ou mesmo remiss o de sintomas depressivos, como já foi caracterizado com o uso de estradiol em mulheres em perimenopausa e com a administra o de testosterona após a menopausa. Este artigo aborda, por revis o da literatura, os diversos papéis atribuídos aos horm nios sexuais no desenvolvimento e tratamento das queixas depressivas. Estudos sobre a eficácia terapêutica de estrógenos, testosterona e DHEA nos quadros depressivos s o discutidos de forma crítica. Em essência, existem resultados preliminares bastante promissores, particularmente quanto ao uso de estradiol e testosterona em subpopula es específicas para alívio de sintomas depressivos. Futuras investiga es devem melhor definir a utiliza o de horm nios como agente depressivo monoterápico ou adjuntivo, bem como delinear os riscos e as contra-indica es associados a seu uso.

Abstract: coral reefs are quite diverse ecosystems that carry out several ecological functions and plays a relevant socioeconomic role. the artisan fishing of octopi (octopus spp.) is practiced for the survival of part of the inhabitants of coroa vermelha community, in the south of the state of bahia. we intended to study the knowledge of the octopi fishermen of coroa vermelha using the comprehensive ethnoecological proposal of marques. the data were collected between july, 2006 and april, 2008 through direct observation and from interviews with fishermen met by chance and through the "native specialists" criterion. twenty semi-structured interviews were carried out following an itinerary of pre-established questions about the activity of octopi capture, and the biological and ecological aspects of the resource. the data showed that the fishermen have knowledge about biological and ecological aspects of the octopi. two capture techniques are used: octopus fishing (polvejamento) in the reefs and through diving. two specific folk are recognized: the "normal octopus" (octopus insularis) and the "east octopus" (octopus macropus (?)). the intervieews demonstrated ecological knowledge sometimes compatible with the scientific literature, mainly in which concerns the trophic ecology and behavior of the octopi.
