Violência intrafamiliar contra a criança na perspectiva de familiares: uma compreensão à luz de Alfred Schutz

A multidimensionalidade e a consistência empírica da violência convidam aos questionamentos, debates e reflexões acerca desse fenômeno. A violência intrafamiliar contra a criança consiste em formas agressivas de membros da família se relacionarem adotando essa prática como solução de conflitos e estratégia para a correção e educação das crianças. Objeto de estudo: a violência intrafamiliar à criança na perspectiva de familiares. Objetivos: Identificar os atos considerados violentos contra a criança na perspectiva de familiares; descrever as implicações desses atos violentos na vida da criança sob a ótica de familiares; conhecer quais as atitudes que os familiares consideram importantes para a prevenção da violência contra a criança e discutir a violência intrafamiliar à criança na perspectiva de familiares a luz da fenomenologia sociológica de Alfred Schutz. Descrição metodológica: Trata-se de estudo de natureza qualitativo desenvolvido em um ambulatório de pediatria de um hospital universitário do município do Rio de Janeiro, com a participação de 12 familiares. Para a interpretação do material empírico foi utilizada a análise de conteúdo de Bardin na modalidade temática. O referencial teórico da fenomenologia sociológica de Alfred Schutz sustentou a discussão dos resultados. Resultados: Emergiram 6 (seis) categorias analíticas, a saber: Violência nas relações familiares; Palavras que ferem; Formas silenciosas de descuido e descaso para com a vida do outro; Violência gera violência; Implicações da violência intrafamiliar na vida da criança; Falar com a criança para evitar a violência. Os familiares a partir de uma relação anônima entendem a violência intrafamiliar contra a criança na perspectiva de um constructo teórico, na qual se situam como espectadores e não como perpetradores dos atos violentos. Para eles, os castigos físicos, a violência psicológica, a negligência e o abandono praticados pelas pessoas são considerados violência intrafamiliar contra a criança. Práticas como palmadinhas e tapinhas foram descritas como forma de correção e educação da criança. No se refere às implicações dos atos violentos na vida da criança apontaram aquelas que podem levar marcas profundas na memória da criança vitimizada, bem como em sua vida sócio-afetiva. O estudo possibilitou a aproximação ao conhecimento de uma realidade que afeta inúmeras crianças, onde os familiares sinalizaram que a melhor maneira de se prevenir a violência intrafamiliar é por meio do estabelecimento de uma conversa esclarecedora com a criança, abordando os assuntos pertinentes para cada ocasião com que se deparam. A inserção dessa temática desde os cursos de graduação para profissionais que lidam com a criança e sua família poderá ampliar os estudos neste campo e subsidiar a formação desses profissionais para lidar de forma adequada com o fenômeno da violência intrafamiliar.

The reproductive cycle of the thorny skate (Amblyraja radiata) in the western Gulf of Maine

The thorny skate (Amblyraja radiata) is a large species of skate that is endemic to the waters of the western north Atlantic in the Gulf of Maine. Because the biomass of thorny skates has recently declined below threshold levels mandated by the Sustainable Fisheries Act, commercial harvests from this region are prohibited. We have undertaken a comprehensive study to gain insight into the life history of this skate. The present study describes and characterizes the reproductive cycle of female and male thorny skates, based on monthly samples taken off the coast of New Hampshire, from May 2001 to May 2003. Gonadosomatic index (GSI), shell gland weight, follicle size, and egg case formation, were assessed for 48 female skates. In general, these reproductive parameters remained relatively constant throughout most of the year. However, transient but significant increases in shell gland weight and GSI were obser ved during certain months. Within the cohort of specimens sampled monthly throughout the year, a subset of females always had large preovulatory follicles present in their ovaries. With the exception of June and September specimens, egg cases undergoing various stages of development were observed in the uteri of specimens captured during all other months of the year. For males (n=48), histological stages III through VI (SIII−SVI) of spermatogenesis, GSI, and hepatosomatic index (HSI) were examined. Although there appeared to be monthly fluctuations in spermatogenesis, GSI, and HSI, no significant differences were found. The production and maintenance of mature spermatocysts (SVI) within the testes was observed throughout the year. These findings collectively indicate that the thorny skate is reproductively active year round.

Estimating exploitable stock biomass for the Maine green sea urchin (Strongylocentrotus droebachiensis) fishery using a spatial statistics approach

The objective of this study was to investigate the spatial patterns in green sea urchin (Strongylocentrotus droebachiensis) density off the coast of Maine, using data from a fishery-independent survey program, to estimate the exploitable biomass of this species. The dependence of sea urchin variables on the environment, the lack of stationarity, and the presence of discontinuities in the study area made intrinsic geostatistics inappropriate for the study; therefore, we used triangulated irregular networks (TINs) to characterize the large-scale patterns in sea urchin density. The resulting density surfaces were modified to include only areas of the appropriate substrate type and depth zone, and were used to calculate total biomass. Exploitable biomass was estimated by using two different sea urchin density threshold values, which made different assumptions about the fishing industry. We observed considerable spatial variability on both small and large scales, including large-scale patterns in sea urchin density related to depth and fishing pressure. We conclude that the TIN method provides a reasonable spatial approach for generating biomass estimates for a fishery unsuited to geostatistics, but we suggest further studies into uncertainty estimation and the selection of threshold density values.

Age and growth estimates of the thorny skate (Amblyraja radiata) in the western Gulf of Maine

The northwest Atlantic population of thorny skates (Amblyraja radiata) inhabits an area that ranges from Greenland and Hudson Bay, Canada, to South Carolina. Despite such a wide range, very little is known about most aspects of the biology of this species. Recent stock assessment studies in the northeast United States indicate that the biomass of the thorny skate is below the threshold levels mandated by the Sustainable Fisheries Act. In order to gain insight into the life history of this skate, we estimated age and growth for thorny skates, using vertebral band counts from 224 individuals ranging in size from 29 to 105 cm total length (TL). Age bias plots and the coefficient of variation indicated that our aging method represents a nonbiased and precise approach for the age assessment of A. radiata. Marginal increments were significantly different between months (Kruskal-Wallis P<0.001); a distinct trend of increasing monthly increment growth began in August. Age-at-length data were used to determine the von Bertalanffy growth parameters for this population: L∞ = 127 cm (TL) and k= 0.11 for males; L∞ = 120 cm (TL) and k= 0.13 for females. The oldest age estimates obtained for the thorny skate were 16 years for both males and females, which corresponded to total lengths of 103 cm and 105 cm, respectively.

Humpback and Fin Whaling in the Gulf of Maine from 1800 to 1918

The history of whaling in the Gulf of Maine was reviewed primarily to estimate removals of humpback whales, Megaptera novaeangliae, especially during the 19th century. In the decades from 1800 to 1860, whaling effort consisted of a few localized, small-scale, shore-based enterprises on the coast of Maine and Cape Cod, Mass. Provincetown and Nantucket schooners occasionally conducted short cruises for humpback whales in New England waters. With the development of bomb-lance technology at mid century, the ease of killing humpback whales and fin whales, Balaenoptera physalus, increased. As a result, by the 1870’s there was considerable local interest in hunting rorquals (baleen whales in the family Balaenopteridae, which include the humpback and fin whales) in the Gulf of Maine. A few schooners were specially outfitted to take rorquals in the late 1870’s and 1880’s although their combined annual take was probably no more than a few tens of whales. Also in about 1880, fishing steamers began to be used to hunt whales in the Gulf of Maine. This steamer fishery grew to include about five vessels regularly engaged in whaling by the mid 1880’s but dwindled to only one vessel by the end of the decade. Fin whales constituted at least half of the catch, which exceeded 100 animals in some years. In the late 1880’s and thereafter, few whales were taken by whaling vessels in the Gulf of Maine.
