This series will include all those people who, by means of their contributions, great and small, played a part in the consolidation of ichthyology in Argentina. The general plan of this work consists of individual factsheets containing a list of works by each author, along with reference bibliography and, whenever possible, personal pictures and additional material. The datasheets will be published primarily in chronological order, although this is subject to change by the availability of materials for successive editions. This work represents another approach for the recovery and revalorization of those who set the foundations of Argentine ichthyology while in diverse historical circumstances. I expect this to be the beginning of a major work that achieves the description of such a significant part of the history of natural sciences in Argentina.

O trabalho expõe a consolidação do direito à verdade pelo Direito Internacional e a complementaridade entre as comissões da verdade e os tribunais, mecanismos de justiça de transição, como a combinação que melhor lhe confere aplicabilidade. Primeiramente, a tese reivindica que a transição e a consolidação democrática devem se dar por meio da prestação de contas com o passado, o que se torna possível na medida em que se promoveram a partir da 2a Guerra Mundial significativas alterações no Direito Internacional, que se afasta do paradigma vesfaliano de soberania. Aborda-se assim o excepcional desenvolvimento do Direito Internacional dos Direitos Humanos, do Direito Internacional Humanitário e do Direito Penal Internacional, centralizados na ideia de responsabilidade. A tese também abrange o desenvolvimento do direito à verdade no seio da Organização das Nações Unidas e dos sistemas regionais de proteção de direitos humanos, tendo alcançado o status de norma imperativa ou peremptória, sendo explorados os obstáculos ao seu exercício como no caso de anistias e outras medidas similiares como a prescrição, a justiça militar e a coisa julgada. Enfrentam-se, ainda, as potencialidades e limites da verdade que resulta de comissões da verdade e dos tribunais, concebida esta como conhecimento sobre os fatos e o reconhecimento da responsabilidade pelo ocorrido. O trabalho aborda temas como a independência e imparcialidade das comissões de verdade, seus poderes e o alcance de suas conclusões e recomendações. Por sua vez, com vistas a identificar as verdades a serem alcançadas pelos tribunais, privilegia-se o processo criminal, por se entender que a sentença penal pressupõe o exercício mais completo do devido processo. A imperatividade do direito à verdade é também demonstrada pela defesa da participação da vítima no processo criminal e da admissão de culpa por parte do acusado -- ambos consagrados pelo Tratado de Roma. Por fim, a tese analisa alguns cenários para a complementaridade entre estes dois mecanismos de justiça de transição, fazendo o estudo dos casos do Chile, Peru, Serra Leoa e Quênia, casos estes permeados pelo Direito Internacional, seja pela influência da jurisdição universal ou pelo impacto da jurisdição internacional. O caso brasileiro, por certo, não se ajusta a nenhum destes cenários. Sua caracterização como um diálogo em aberto, para efeitos deste trabalho, pressupõe que o Brasil encontra-se em um importante momento de decisão sobre a complementaridade entre comissões da verdade e tribunais - a recente aprovação da Comissão Nacional da Verdade deve conviver com o aparente conflito entre a decisão do Supremo Tribunal Federal, que afirmou a constitucionalidade da Lei de Anistia de 1979, e a decisão da Corte Interamericana no caso Araguaia, que entende nulos os dispositivos da lei que obstaculizam o processamento dos responsáveis, ambas no ano de 2010 - com a oportunidade de demonstrar que a passagem do tempo não arrefece as obrigações a que se comprometeu no cenário internacional.

Kv7.2 (KCNQ2) is the principal molecular component of the slow voltage gated M-channel, which strongly influences neuronal excitability. Calmodulin (CaM) binds to two intracellular C-terminal segments of Kv7.2 channels, helices A and B, and it is required for exit from the endoplasmic reticulum. However, the molecular mechanisms by which CaM controls channel trafficking are currently unknown. Here we used two complementary approaches to explore the molecular events underlying the association between CaM and Kv7.2 and their regulation by Ca2+. First, we performed a fluorometric assay using dansylated calmodulin (D-CaM) to characterize the interaction of its individual lobes to the Kv7.2 CaM binding site (Q2AB). Second, we explored the association of Q2AB with CaM by NMR spectroscopy, using N-15-labeled CaM as a reporter. The combined data highlight the interdependency of the N- and C-lobes of CaM in the interaction with Q2AB, suggesting that when CaM binds Ca2+ the binding interface pivots between the N-lobe whose interactions are dominated by helix B and the C-lobe where the predominant interaction is with helix A. In addition, Ca2+ makes CaM binding to Q2AB more difficult and, reciprocally, the channel weakens the association of CaM with Ca2+.

We compared numbers of strikes, proportions of fish that hooked up after strikes, proportions of fish that stayed on hook (retained) after hook up, and numbers of fish caught between circle and J hooks rigged with dead natural fish bait (ballyhoo)and trolled for three oceanic predator species: dolphinfish (Coryphaena hippurus), yellowfin tuna (Thunnus albacares), and wahoo (Acanthocybium solandri). Interactions were compared between circle and J hooks fished on 75 trips by two user groups (charter and recreational fishermen). Hooks were affixed to three species-specific leader types most commonly fished in this region: monofilament (dolphinfish), fluorocarbon (tuna), and wire (wahoo). Numbers of fish caught per trip and three potential mechanisms that might inf luence numbers caught (i.e., number of strikes, proportion of fish hooked, and proportion retained) were modeled with generalized linear models that considered hook type, leader type, species, user (fishing) group, and wave height as main effects. Hook type was a main effect at the catch level; generally, more fish were caught on J hooks than on circle hooks. The effect of hook type on strike rates was equivocal. However, J hooks had a greater proportion of hook-ups than did circle hooks. Finally, the proportion of fish retained once hooked was generally equal between hook types. We found similar results when data from additional species were pooled as a “tuna” group and a “mackerel” group. We conclude that J hooks are more effective than circle hooks at the hook-up level and result in greater numbers of troll-caught dolphinfish, tunas

Trawling was conducted in the Charleston, South Carolina, shipping channel between May and August during 2004–07 to evaluate loggerhead sea turtle (Caretta caretta) catch rates and demographic distributions. Two hundred and twenty individual loggerheads were captured in 432 trawling events during eight sampling periods lasting 2–10 days each. Catch was analyzed by using a generalized linear model. Data were fitted to a negative binomial distribution with the log of standardized sampling effort (i.e., an hour of sampling with a net head rope length standardized to 30.5 m) for each event treated as an offset term. Among 21 variables, factors, and interactions, five terms were significant in the final model, which accounted for 45% of model deviance. Highly significant differences in catch were noted among sampling periods and sampling locations within the channel, with greatest catch furthest seaward consistent with historical observations. Loggerhead sea turtle catch rates in 2004–07 were greater than in 1991–92 when mandatory use of turtle excluder devices was beginning to be phased in. Concurrent with increased catch rates, loggerheads captured in 2004–07 were larger than in 1991–92. Eighty-five percent of loggerheads captured were ≤75.0 cm straight-line carapace length (nuchal notch to tip of carapace) and there was a 3.9:1 female-to-male bias, consistent with limited data for this location two decades earlier. Only juvenile loggerheads ≤75.0 cm possessed haplotypes other than CC-A01 or CC-A02 that dominate in the region. Six rare and one un-described haplotype were predominantly found in June 2004.

Diet, gastric evacuation rates, daily ration, and population-level prey demand of bluefin tuna (Thunnus thynnus) were estimated in the continental shelf waters off North Carolina. Bluefin tuna stomachs were collected from commercial fishermen during the late fall and winter months of 2003–04, 2004–05, and 2005–06. Diel patterns in mean gut fullness values were used to estimate gastric evacuation rates. Daily ration determined from mean gut fullness values and gastric evacuation rates was used, along with bluefin tuna population size and residency times, to estimate population-level consumption by bluefin tuna on Atlantic menhaden (Brevoortia tyrannus). Bluefin tuna diet (n= 448) was dominated by Atlantic menhaden; other teleosts, portunid crabs, and squid were of mostly minor importance. The time required to empty the stomach after peak gut fullness was estimated to be ~20 hours. Daily ration estimates were approximately 2% of body weight per day. At current western Atlantic population levels, bluefin tuna predation on Atlantic menhaden is minimal compared to predation by other known predators and the numbers taken in commercial harvest. Bluefin tuna appear to occupy coastal waters in North Carolina during winter to prey upon Atlantic menhaden. Thus, changes in the Atlantic menhaden stock status or distribution would alter the winter foraging locations of bluefin

The community structure of fishes associated with pelagic Sargassum spp. and open water lacking Sargassum was examined during summer and fall cruises, 1999–2003, in the Gulf Stream off North Carolina. Significantly more individual fishes (n= 18,799), representing at least 80 species, were collected from samples containing Sargassum habitat, compared to 60 species (n=2706 individuals) collected from openwater habitat. The majority (96%) of fishes collected in both habitats were juveniles, and planehead filefish (Stephanolepis hispidus) dominated both habitats. Regardless of sampling time (day or night), Sargassum habitat yielded significantly higher numbers of individuals and species compared with open-water collections. Overall, fishes collected by neuston net tows from Sargassum habitat were significantly larger in length than fishes collected from open-water habitat with neuston nets. A significant positive, linear relationship existed between numbers of fishes and the quantity of Sargassum collected by neuston net. Underwater video recordings indicated a layered structure of fishes among and below the algae and that smaller fishes were more closely associated with the algae than larger fishes. Observations of schooling behaviors of filefishes (Monacanthidae), dolphinfish (Coryphaena hippurus), and jacks (Carangidae), and fish-jellyfish associations were also recorded with an underwater video camera. Our data indicate that Sargassum provides a substantial nursery habitat for many juvenile fishes off the U.S. southeast coast.

Age, growth, and reproductive data were obtained from dolphinfish (Coryphaena hippurus, size range: 89 to 1451 mm fork length [FL]) collected between May 2002 and May 2004 off North Carolina. Annual increments from scales (n=541) and daily increments from sagittal otoliths (n=107) were examined; estimated von Bertalanffy parameters were L∞ (asymptotic length)=1299 mm FL and k (growth coefficient)=1.08/yr. Daily growth increments reduced much of the residual error in length-at-age estimates for age-0 dolphinfish; the estimated average growth rate was 3.78 mm/day during the first six months. Size at 50% maturity was slightly smaller for female (460 mm FL) than male (475 mm FL) dolphinfish. Based on monthly length-adjusted gonad weights, peak spawning occurs from April through July off North Carolina; back-calculated hatching dates from age-0 dolphinfish and prior reproductive studies on the east coast of Florida indicate that dolphinfish spawning occurs year round off the U.S. east coast and highest levels range from January through June. No major changes in length-at-age or size-at-maturity have occurred since the early 1960s, even after substantial increases in fishery landings.

This study examined the sexual differentiation and reproductive dynamics of striped mullet (Mugil cephalus L.) in the estuaries of South Carolina. A total of 16,464 specimens were captured during the study and histological examination of sex and maturity was performed on a subsample of 3670 fish. Striped mullet were sexually undifferentiated for the first 12 months, began differentiation at 13 months, and were 90% fully differentiated by 15 to 19 months of age and 225 mm total length (TL). The defining morphological characteristics for differentiating males was the elongation of the protogonial germ tissue in a corradiating pattern towards the center of the lobe, the development of primary and secondary ducts, and the lack of any recognizable ovarian wall structure. The defining female characteristics were the formation of protogonial germ tissue into spherical germ cell nests, separation of a tissue layer from the outer epithelial layer of the lobe-forming ovarian walls, a tissue bud growing from the suspensory tissue that helped form the ovary wall, and the proliferation of oogonia and oocytes. Sexual maturation in male striped mullet first occurred at 1 year and 248 mm TL and 100% maturity occurred at age 2 and 300 mm TL. Female striped mullet first matured at 2 years and 291 mm total length and 100% maturity occurred at 400 mm TL and age 4. Because of the open ocean spawning behavior of striped mullet, all stages of maturity were observed in males and females except for functionally mature females with hydrated oocytes. The spawning season for striped mullet recruiting to South Carolina estuaries lasts from October to April; the majority of spawning activity, however, occurs from November to January. Ovarian atresia was observed to have four distinct phases. This study presents morpholog ical analysis of reproductive ontogeny in relation to size and age in South Carolina striped mullet. Because of the length of the undifferentiated gonad stage in juvenile striped mullet, previous studies have proposed the possibility of protandric hermaphrodism in this species. The results of our study indicate that striped mullet are gonochoristic but capable of exhibiting nonfunctional hermaphroditic characteristics in differentiated mature gonads.

O presente estudo investiga os posicionamentos e a agência de participantes de um Sarau Bilíngue. O Sarau é uma proposta didática / pedagógica, desenvolvida no Curso Bilíngue de Pedagogia do Instituto Nacional de Educação de Surdos INES e visa integrar surdos e ouvintes, de forma lúdica, proporcionando práticas de letramento que envolvem dramatizações, traduções e adaptações de textos da língua portuguesa para LIBRAS, contribuindo para o acesso à literatura e à música, o rompimento de barreiras e a quebra de preconceitos mediada pela arte. O estudo tem caráter interdisciplinar e de cunho etnográfico, dialogando com os campos da Sociologia, Ciências Sociais, Fonoaudiologia, Educação, Surdez e localizando-se na área da Linguística Aplicada. É realizado a partir de uma entrevista de grupo, analisada qualitativa e interpretativamente. A análise é desenvolvida à luz dos conceitos de posicionamento (DAVID e HARRÉ,1999), agência (AHEARN, 2001) e construções identitárias (HALL, 2006; CASTELLS, 1999) sinalizados por pistas lexicais. A análise mostra os posicionamentos, agência e construções identitárias emergentes durante a entrevista e como contribuem para a construção do letramento (GEE, 1990; KLEIMAN, 2005) dos participantes a partir de sua participação em um Sarau Bilíngue

Este trabalho busca, através de um estudo que vincula literatura e pensamento crítico social, explorar as relações entre os processos de marginalização literária e algumas alternativas intelectivas acerca das noções de marginalidade e anormalidade. Seu corpus literário abarca três livros de escritores brasileiros, que, além de não terem logrado inserção no que poderia ser entendido como um cânone nacional, destacam-se ainda pela temática de suas obras, que, em si mesmas, trazem o problema da marginalização. Assim, Desabrigo, de Antônio Fraga; Quarto de despejo, de Carolina de Jesus; e Hospício é Deus, de Maura Lopes Cançado são abordadas a partir das reflexões desenvolvidas, especialmente, por Michel Foucault e Georges Canguilhem a respeito das estratégias de produção de anormais, revelando o quanto a marginalização, antes de ser uma consequência de uma inadequação a normas pré-existentes, pode, de fato, ser a própria fonte de produção destas normas. Buscando valorizar tanto as convergências, quanto as distinções possíveis nas obras daqueles três escritores, o trabalho procura se afastar de uma perspectiva que apreenderia suas obras como produções isoladas e desprestigiadas, para nelas encontrar a potência da afirmação de um discurso literário que tanto se apresentou como denúncia e contestação, quanto como um cuidadoso trabalho de expressão literária e, portanto, de expressão social.
