Abuso sexual infantil é tomado na acepção do construcionismo social, como tipo classificatório, e com uma abordagem histórica. As fortes cargas moral e emocional da categoria são sublinhadas, assim como a noção de carreira moral da criança abusada e de abusador. A psicologia é um dos campos e disciplinas que construiu a categoria e a molda diariamente em suas práticas, teorizações e inclusão em instituições sociais e políticas. A dissertação busca analisar esta moldagem numa amostra de laudos psicológicos relativos a acusações de abuso sexual, constantes de processos de Varas de Família e Varas Criminais no Judiciário do Rio de Janeiro. Os laudos analisados são de autoria de psicólogos do quadro do Tribunal de Justiça do Estado do Rio de Janeiro (TJ-RJ), de psicólogos nomeados ad hoc, de instituições de atendimento a vítimas de violência sexual e de consultórios particulares. Como complementação, são analisadas entrevistas feitas com cinco psicólogos do quadro do TJ-RJ sobre laudos em acusações de abuso sexual infantil e sobre a categoria, afirmando a presença permanente desta, apesar de não mais como um boom (ocorrido no início dos anos 2000), em processos de guarda e visitação de filhos e criminais. A análise constatou a presença de duas posturas da psicologia, a das Varas de Família, que trabalha com a correlação litígio-falsa acusação de abuso sexual- alienação parental, em visão determinista, e a das Varas Criminais, marcada pela exclusão da avaliação do homem acusado e por fortes preconcepções, apoiadas na psicologia do abuso sexual, sobre a amplitude dos abusos sexuais e o testemunho da criança vítima e dos acusadores. Noções controversas de manuais clássicos da psicologia do abuso sexual, da psiquiatria e do senso comum sobre vitimização, sequelas, síndromes, pedofilia estão presentes nos laudos, assim como, mais raramente, o reconhecimento da sexualidade infantil e adolescente. O homem pode aparecer como um pai vitimizado ou um monstro moralmente desqualificado.

Após centenas de anos de exploração dos recursos naturais, a Terra começa a mostrar as consequências de seu uso descontrolado. Nas últimas quatro décadas o homem tem voltado seus olhos para a causa ambiental de forma mais intensa e conciliadora. Como resultado dessa nova maneira de pensar, a sociedade e a indústria, que se veem obrigadas a se adaptar às novas tendências de mercado e novas formas de produção. Produzindo melhor e consumindo menos, fecha-se uma cadeia de produção estruturada. Mas, por mais que se invista em tecnologia, um problema sempre existirá: o resíduo, incluindo-se nesta categoria, também os rejeitos produzidos pelas atividades humanas. O tratamento de resíduos é uma questão de difícil solução mesmo à longo prazo. As cooperativas de reciclagem se apresentam como uma nova forma de empreendimento, inserido em moldes mais modernos, baseados nos princípios da Economia Solidária, existente em países da Europa e América Latina, com destaque para o Brasil. É nesse cenário que se encontra o objeto de estudo da pesquisa: a mulher catadora/recicladora. Estatísticas apontam que em muitos estados do país elas chegam a 65% dos trabalhadores. Muitas dessas cooperativas são administradas por mulheres, quando não, frequentadas majoritariamente por elas. O objetivo geral desta pesquisa é analisar como se configuram as relações de gênero e divisão sexual do trabalho, partindo da visão das dirigentes das cooperativas. Questões semiestruturadas, com abordagem qualitativa foram elaboradas e aplicadas à nove líderes de associação de catadores da região metropolitana do Rio de Janeiro e do Vale do Paraíba Fluminense (Resende). As entrevistas foram filmadas para a elaboração de um documentário acadêmico, também produto desta pesquisa. Foram encontradas na pesquisa, convergências em relação à divisão sexual do trabalho, partindo de princípios sexistas onde os homens deveriam se encarregar do trabalho mais pesado e as mulheres do trabalho mais fino, como a triagem. No entanto, a realidade apontada pelas entrevistadas nos remete à naturalização do trabalho multitarefa, onde elas se incubem de realizar todos os procedimentos, estando ou não na presença de homens na cooperativa.

With the southern New England lobster fishery in distress, lobster fishermen have focused more effort toward harvesting channeled whelk (Busycotypus canaliculatus). However, minimal research has been conducted on the life history and growth rates of channeled whelk. Melongenid whelks generally grow slowly and mature late in life, a characteristic that can make them vulnerable to overfishing as fishing pressure increases. We sampled channeled whelk from Buzzards Bay, Massachusetts, in August 2010 and in July 2011, studied their gonad development by histology, and aged them by examining opercula. Males had a slower growth rate and a lower maximum size than females. Male whelk reached 50% maturity (SM50) at 115.5 mm shell length (SL) and at the age of 6.9 years. Female whelk reached SM50 at 155.3 mm SL and at the age of 8.6 years. With a minimum size limit of 69.9 mm (2.75 in) in shell width, males entered the fishery at 7.5 years, a few months after SM50, but females entered the fishery at 6.3 years, approximately 2 years before SM50. Increased fishing pressure combined with slow growth rates and the inability to reproduce before being harvested can easily constrain the long-term viability of the channeled whelk fishery in Massachusetts.

An experiment was conducted for rearing of Meni, Nandus nandus in laboratory condition for seven months with the objective to select appropriate feed for the species and to develop a rearing technique of the species up to the stage of sexual maturation. Different trials were conducted using artificial feed (35.5% protein), dead fresh kachki (Carica soborna), dead fresh prawn (Macrobrachium lamarrei) and live prawn (Macrobrachium lamarrei). The provision of bottom sediment did not significantly influence the growth of fish. Between dead fresh kachki and dead fresh prawn, the fish preferred dead fresh prawn. The fish was found to be reluctant to take dead fresh kachki and prawn as food unless they became very hungry. The fish was found actively feeding on live prawn. The FCR of the prawn as food for N. nandus was found to be 2.5. From the study, it was observed that in laboratory rearing N. nandus preferred live prawn as food than artificial feed, dead fresh kachki and dead fresh prawn. The fish fed on live prawn became sexually matured (eggs or white milt extruded by gentle pressure on the abdomen of the fish) in the laboratory at the end of the experiment.

A thorough comparative study on the urinogenital papilla and sexual dimorphism has been made for the first time in both the sexes of twelve Indian gobiids: Glassogobius giuris (Hamilton); Acentrogobius cyanomos (Bleeker); Eleotriodes muralis (Valenciennes); Parapocryptes serperaster (Richardson); Apocryptes bato (Hamilton); Scartclaos viridis (Hamilton); Boleophthalmus boddarti (Pallas), Periophthalmus schlosseri (Pallas); P. koelreuteri (Pallas); Taenioides anguillaris (Linnaeus); T. buchanani (Day); Odontamblyopus rubicundus (Hamilton). The urinogenital papilla, originating as a free muscular organ from the ventral surface of the body-wall and shortly behind anus, is present in both the sexes. It is an important organ of primary sex recognition in all species. In case of male the papilla is conical, broad at the base and in female it is either flattened, distally truncated or bluntly rounded. The presence of permanent colour mark over the specific region of the body surface is another secondary sexual character in a few species. Besides, colouration may also be a nuptial secondary sex character developed in some during peak breeding season. The enlargement and colouration of the organ is subject to seasonal variations parallel to the seasonal gonadal cycle. The histological architecture of the papilla shows a high degree of cellular specialization and an interrelationship to the urinary and genital ducts. The functional efficacy and significance of the papilla in the breeding biology of these fishes has been discussed.

The macroscopic scale used for determination of sexual maturity in shrimps was tested against objective parameters namely the gonad-somatic index and the size of oocytes. The two main species caught in Mozambique, Penaeus indicus and Metapenaeus monoceros, were the object of the work. In order to reduce the subjectivity in the macroscopic exam, a table with the colours representative of each stage is presented. Since this study was conducted over a period of 13 consecutive months and there were observations from previous years, the sexual cycle of the two species is also presented, as well as an estimate of the size at first maturity.

Benni (Barbus sharpeyi) is valuable fish that Khuzastan fisheries office propagated it artificially in Susangerd Fish Propagation Center every year. Pituitary gland is used for this aim but female fish lost their fertilization power after 2-3 years, so in present research, new hormone, that is called Ghrelin. The aims of this research are histology, hormonal, zygote and larval generation studies and comparing the results with each other. Ghrelin is a multifunctional peptidyl hormone which increases GTH-II in fish, amphibian, and birds and mammalian so its effect on Benni sexual maturation was studied. Human Ghrelin (hGRL) was obtained from ANASPEC, Canada, with 28 amino acids. In the present study, three levels of ghrelin including 0 (sham treatments), 0.10 (treatment 1) and 0.15 μg/g (treatment 2) body wt and one level of pituitary gland 4000 μg/g (pituitary treatment) with two replications were used. 56 specimens were injected intraperitonealy and their ghrelin level was evaluated immediately after injection and after 24 h. Control fish(n=16) were just injected by physiological saline. For hormonal studies sham and experimental fish(n=40) were anesthetized with MS-222 at a concentration of 250 mg l-1, and blood samples were collected and kept at 4ْC, then spun to collect serum. Serum samples were stores at -20ْC until the RIA for CTH-II. For histology studies immediately after injection a piece of ovary was collected from control fish (Sham zero) after being anesthetized. The sampled ovaries were fixed in Buin solution and embedded in paraffin, and stained to Sections of 5–6 μm using haematoxylin and eosin. The ovarian samples were performed with a compound microscope. Histology and micrometry studies had done. The mature oocytes had given from mature fish, then weighted and the working fecundity were counted. The mature oocytes fertilized, the eggs were incubated and the percentage of fertilization was calculated. After 72h the eggs hatched and the percentage of hatch was counted. The percentage of hindrance was calculated after 6 days. Hormonal results indicate that ghrelin and pituitary increase significantly the GTH-II level in comparison to sham. Macroscopic observations (before taking ovary) showed that ovaries with green colored have couple oval structure located in the abdominal cavity. Microscopic studies of dissected ovaries indicated simultaneous growth of 127 oocytes with 6 stages. The type of the ovary is asynchronous. The results indicated that both of the ghrelin treatment increased the percentage of mature follicles followed by decrease of immature follicles. There were significant differences (P<0.05) between the number of mature and immature follicles. Average diameter of follicle in both of the ghrelin treatment was significantly (P<0.05) declined in the stages of the vitellogenesis when the result compared to the other treatment. Just treatment 1 and pituitary treatment can give mature oocytes. The fecundity of pituitary treatment significantly increase in comparision to ghrelin treatment (P<0.05). In food-restricted fish where endogenous ghrelin levels are known to be increased, a chronic administration of ghrelin induces overt negative effect in releasing mature oocytes. The percentage of fertilization was significantly increase (P<0.05) in ghrelin t. in comparison to pituitary t. and the percentage of hatch was significantly increase (P<0.05) in pituitary t. in comparison to ghrelin t. There was no significant difference (P>0.05) in terms of percentage of hindrance between treatments. In conclusion, the present study demonstrated that ghrelin has positive effect on the level of GTH-II, oocyte maturation, ovarian vitellogenesis and the number of mature follicles of Barbus sharpeyi ovary. Increasing of the mature follicles number reduces their average diameter, indicating stimulating effect of ghrelin in sexual maturation of Barbus sharpeyi.The ghrelin and pituitary treatment have equal chance in the post-stage of spawning.
