Gerando eus, tecendo redes e trançando nós: ditos e não ditos das professoras e estudantes negras nos cotidianos do curso de pedagogia

O presente trabalho objetiva compreender como a temática afrobrasileira era abordada nos cotidianos do Curso de Pedagogia, campus I, da Universidade Estadual da Paraíba. A questão norteadora da pesquisa foi descobrir como professoras e estudantes negras se sentem e enfocam essa temática nas suas redes de conhecimentos, práticas e relações. Para tanto, foi preciso adentrar na história do povo negro no Brasil a partir da luta dos movimentos sociais negros buscando entender as noções de raça, racismo, identidade e os limites da educação do/a negro/a ao longo da história brasileira. Neste percurso se dialoga com diversos estudiosos/as como: Santos (2002), Viana (2007), Oliveira (2003, 2006, 2007, 2008), Fernandes (2007), Domingues (2009), Munanga (2002, 2006, 2009), Veiga (2007, 2008)), Pereira (2008, 2009), Gomes (2003, 2006, 2008), Morin (2000), Hall (2003), Moreira e Câmara (2008), dentre outros. Exemplificando a luta e a resistência de mulheres negras são apresentadas as histórias de vida de quatro professoras e quatro estudantes negras, praticantes (CERTEAU, 2007), sujeitos da pesquisa, que expõem o processo de tessitura de suas identidades. Suas narrativas evidenciam indícios de racismo e discriminação que marcaram suas trajetórias, desde o seio familiar, fortalecendo-se na escola, na academia e, para algumas, chegando até o ambiente de trabalho. Uma das professoras é a pesquisadora que, à medida que narra a história de vida das praticantes, tece sua própria história, como mulheres costurando uma colcha de retalhos em que cada estampa retrata os momentos vividos. A metodologia de pesquisa nos/dos/com os cotidianos (ALVES, 2008) foi o caminho percorrido. Além da observação dos cotidianos, foram realizadas conversas (LARROSA, 2003) sobre as histórias de vida (BOSI, 2003; PORTELLI, 1997) e tecidas as narrativas a partir dessas vivências. Estas revelaram que tais mulheres, ao longo de suas histórias, viveram/vivem processos de afirmaçãonegação, visto que suas identidades não são fixas, mas negociações e renegociações (MUNANGA, 2010) que geram alegrias e conflitos. O entendimento do que é Ser Negra é experimentado por cada uma, sem um modelo padrão para suas existências. Elas foram se gerando nas relações com o/a outro/a, em cada contexto familiar, escolar, acadêmico e profissional. São senhoras de suas vidas e mesmo as mais jovens buscam fazer suas histórias com autonomia. São praticantes porque lutaram/lutam para conquistar um lugar na vida, utilizando astúcias e táticas para fabricar (CERTEAU, 2007) meios de enfrentamento das adversidades. As táticas do silêncio, do estudo e do trabalho revelaram que essas mulheres não ficaram invisíveis nem se colocaram como vítimas no espaço social. Assim, urge delinear a superação da visão da pessoa negra a partir dos traços físicos e reconhecer as raízes do povo brasileiro para compreender a história da negritude. A partir da ancestralidade, serão identificadas as origens do povo negro, que poderão trazer o passado de resistência e luta por liberdade, dignidade, cidadania que produzem o orgulho de ser negra. Orgulho que recupera a autoestima e a capacidade de organização e mobilização para combater o racismo e as desigualdades raciais. Os cursos de formação docente precisam abordar essa temática para capacitar os/as futuros/as professores/as nessa tarefa. Essa abordagem envolve o ensinaraprender, em que professores/as e estudantes assumem compromisso com uma educação crítica e inclusiva. A reflexão entre os/as docentes formadores/as nessa perspectiva plural e intercultural poderia ajudar na superação do eurocentrismo ainda presente nos conteúdos e nas mentalidades. Sob essa ótica, tecer um processo de formação docente no Curso de Pedagogia, comprometido com uma educação inclusiva, considera um contínuo fazerdesfazer, na tessitura de um diálogo permanente entre a práticateoriaprática, num movimento de pesquisaintervenção. Isso implica a reflexão da trajetória pessoal e coletiva e a articulação da ação pedagógica com um projeto político de transformação da sociedade excludente em sociedade plural e solidária. Os não ditos necessitam de aprofundamento em trabalhos posteriores, pois os silenciamentos se referem ao passado próximo e as relações interraciais na família, na academia e também nos ambientes de trabalho. Será que não existe mais racismo? Ou este foi naturalizado dificultando sua identificação nos cotidianos? Os limites do processo de introjeção do racismo, que provocam a invisibilidade de algumas praticantes, são novos desafios para estudos futuros. Assim, percebo que colcha de retalhos tecida ao longo desta trajetória não é justaposição como usualmente é entendida. Para além disto, significa a socialização das experiências vividas nos cotidianos das praticantes, a fim de inspirar atitudes de combate ao racismo que se ampliem para o contexto social.

This brief reports highlights the significance of scale readings of salmon. The reasons for colour change of scales and scale rings are briefly explained. Scale readings of salmon fry from the River Lune in the north west of England are presented. The salmon was captured in 1957/58.

Órfãos da saúde pública: violação dos direitos de uma geração atingida pela política de controle da hanseníase no Brasil

Este trabalho tem como objetivo principal investigar a história dos filhos sadios separados dos pais doentes de hanseníase que foram isolados compulsoriamente em leprosários por determinação do Estado brasileiro. Através da metodologia da pesquisa qualitativa baseada na técnica de história oral, busca-se compreender esta forma de violação de direitos de uma geração que foi atingida pela política de controle da doença no Brasil. Assim, identificamos as circunstâncias desta separação e o destino que teve cada um dos entrevistados e examinamos as relações entre a trajetória social destes sujeitos e a política sanitária determinada pela Saúde Pública brasileira; à luz das consequências sociais e morais causadas por esta determinação profilática. Concluímos que um dos grandes impactos da medida de segregação e afastamento destes indivíduos foi o aprofundamento do estigma social que teve como principais efeitos perversos, o rompimento do vínculo com a família e com as redes de sociabilidade, além da restrição das oportunidades de estudo e de trabalho, conformando um modo de discriminação que se traduz na história de vida dos sujeitos afetados pela doença e de seus familiares.

Life-stage recruitment models for Atlantic cod (Gadus morhua) and haddock (Melanogrammus aeglefinus) on Georges Bank

Ichthyoplankton surveys have been used to provide an independent estimate of adult spawning biomass of commercially exploited species and to further our understanding of the recruitment processes in the early life stages. However, predicting recruitment has been difficult because of the complex interaction of physical and biological processes operating at different spatial and temporal scales that can occur at the different life stages. A model of first-year life-stage recruitment was applied to Georges Bank Atlantic cod (Gadus morhua) and haddock (Melanogrammus aeglefinus) stocks over the years 1977–2004 by using environmental and densitydependent relationships. The best lifestage mortality relationships for eggs, larvae, pelagic juveniles, and demersal juveniles were first determined by hindcasting recruitment estimates based on egg and larval abundance and mortality rates derived from two intensive sampling periods, 1977–87 and 1995–99. A wind-driven egg mortality relationship was used to estimate losses due to transport off the bank, and a wind-stress larval mortality relationship was derived from feeding and survival studies. A simple metric for the density-dependent effects of Atlantic cod was used for both Atlantic cod and haddock. These life stage proxies were then applied to the virtual population analysis (VPA) derived annual egg abundances to predict age-1 recruitment. Best models were determined from the correlation of predicted and VPA-derived age-1 abundance. The larval stage was the most quantifiable of any stage from surveys, whereas abundance estimates of the demersal juvenile stage were not available because of undersampling. Attempts to forecast recruitment from spawning stock biomass or egg abundance, however, will always be poor because of variable egg survival.

Comparison of life history parameters for landed and discarded fish captured off the southeastern United States

Commercial fisheries that are managed with minimum size limits protect small fish of all ages and may affect size-selective mortality by the differential removal of fast growing fish. This differential removal may decrease the average size at age, maturation, or sexual transition of the exploited population. When fishery-independent data are not available, a comparison of life history parameters of landed with those of discarded fish (by regulation) will indicate if differential mortality is occurring with the capture of young but large fish (fast growing phenotypes). Indications of this differential size-selective mortality would include the following: the discarded portion of the target fish would have similar age ranges but smaller sizes at age, maturation, and sexual transition as that of landed fish. We examined three species with minimum size limits but different exploitation histories. The known heavily exploited species (Rhomboplites aurorubens [vermilion snapper] and Pagrus pagrus [red porgy]) show signs of this differential mortality. Their landed catch includes many young, large fish, whereas discarded fish had a similar age range and mean ages but smaller sizes at age than the landed fish. The unknown exploited species, Mycteroperca phenax (scamp), showed no signs of differential mortality due to size-selective fishing. Landed catch consisted of old, large fish and discarded scamp had little overlap in age ranges, had significantly different mean ages, and only small differences in size at age when compared to comparable data for landed fish.

Demographics by depth: spatially explicit life-history dynamics of a protogynous reef fish

Distribution and demographics of the hogfish (Lachnolaimus maximus) were investigated by using a combined approach of in situ observations and life history analyses. Presence, density, size, age, and size and age at sex change all varied with depth in the eastern Gulf of Mexico. Hogfish (64–774 mm fork length and 0–19 years old) were observed year-round and were most common over complex, natural hard bottom habitat. As depth increased, the presence and density of hogfish decreased, but mean size and age increased. Size at age was smaller nearshore (<30 m). Length and age at sex change of nearshore hogfish were half those of offshore hogfish and were coincident with the minimum legal size limit. Fishing pressure is presumably greater nearshore and presents a confounding source of increased mortality; however, a strong red tide occurred the year before this study began and likely also affected nearshore demographics. Nevertheless, these data indicate ontogenetic migration and escapement of fast-growing fish to offshore habitat, both of which should reduce the likelihood of fishing-induced evolution. Data regarding the hogfish fishery are limited and regionally dependent, which has confounded previous stock assessments; however, the spatially explicit vital rates reported herein can be applied to future monitoring efforts.

Ontogenetic patterns and temperature-dependent growth rates in early life stages of Pacific cod (Gadus macrocephalus)

Pacific cod (Gadus macrocephalus) is an important component of fisheries and food webs in the North Pacific Ocean and Bering Sea. However, vital rates of early life stages of this species have yet to be described in detail. We determined the thermal sensitivity of growth rates of embryos, preflexion and postflexion larvae, and postsettlement juveniles. Growth rates (length and mass) at each ontogenetic stage were measured in three replicate tanks at four to five temperatures. Nonlinear regression was used to obtain parameters for independent stage-specific growth functions and a unified size- and temperature-dependent growth function. Specific growth rates increased with temperature at all stages and generally decreased with increases in body size. However, these analyses revealed a departure from a strict size-based allometry in growth patterns, as reduced growth rates were observed among preflexion larvae: the reduction in specific growth rate between embryos and free-swimming larvae was greater than expected based on body size differences. Growth reductions in the preflexion larvae appear to be associated with increased metabolic rates and the transition from endogenous to exogenous feeding. In future studies, experiments should be integrated across life transitions to more clearly define intrinsic ontogenetic and size-dependent growth patterns because these are critical for evaluations of spatial and temporal variation in habitat quality.

Influence of ocean conditions on the timing of early life history events for blue rockfish (Sebastes mystinus) off California

Settled juvenile blue rockfish (Sebastes mystinus) were collected from two kelp beds approximately 335 km apart off Mendocino in northern California and Monterey in central California. A total of 112 rockfish were collected from both sites over 5 years (1993, 1994, 2001, 2002, and 2003). Total age, settlement date, age at settlement, and birth date were determined from otolith microstructure. Fish off Mendocino settled mostly in June and fish off Monterey settled mostly in May (average difference in settlement=23 days). Although the difference in the timing of settlement followed this same pattern for both areas over the five years, settlement occurred later in 2002 and 2003 than in the prior years of sampling. The difference in the timing of settlement was due primarily to differences in birth dates for the two areas. The time of settlement was positively related to upwelling and negatively related to sea level anomaly for most of the months before settlement. Knowledge of the timing of settlement has implications for design and placement of marine protected areas because protection of nursery grounds is frequently a major objective of these protected areas. The timing of settlement is also an important consideration in the planning of surveys of early recruits because mistimed surveys (caused by latitudinal differences in the timing of settlement) could produce biased estimates.

Uma memória ímpar: a trajetória de Arthur Napoleão na sociabilidade musical de dois continentes (1843-1925)

Essa tese tem como objetivo primordial estudar a trajetória musical do pianista português Arthur Napoleão (1843-1925), desde a sua iniciação musical na cidade natal do Porto, até o falecimento no Rio de Janeiro em 1925. Discute-se aqui a relevância da inserção do pianista e de sua música nos meio sócios-culturais dos países da Europa e Américas, em cujas cidades se apresentou durante os primeiros quinze anos de sua carreira. Do mesmo modo, estuda-se também as circunstâncias da permanência do notável intérprete no Brasil, como imigrante radicado, desde 1868, bem como se deu a consolidação da sua nova perspectiva laboral no campo da música, como empreendedor e mediador cultural. E ainda por meio da organização de estabelecimentos comerciais voltados para a venda de pianos e partituras musicais, que se tornaram importantes espaços de sociabilidade musical na Corte, depois capital federal da República, ao longo de sua vida. As numerosas e variadas fontes aqui utilizadas são caudatárias do texto autobiográfico legado por Arthur Napoleão, de 1907. Essas "Memórias", ao mesmo tempo fonte de informação e objeto de estudo, possibilitam traçar, pelo exame vis-à-vis com a documentação restante, a trajetória artística de Arthur Napoleão, desde Portugal até o Brasil, no universo sócio-cultural em transformação, da segunda metade do século XIX ao primeiro quarto do XX.

Distribution and life history of two diminutive flatfishes, Citharichthys gymnorhinus and C. cornutus (Pleuronectiformes: Paralichthyidae), in the western North Atlantic

Citharichthys cornutus and C. gymnorhinus, diminutive flatfishes inhabiting continental shelves in the western Atlantic Ocean, are infrequently reported and poorly known. We identified 594 C. cornutus in 56 different field collections (68–287 m; most between 101–200 m) off the eastern United States, Bahamas, and eastern Caribbean Sea. Historical records and recently captured specimens document the northern geographic range of adults on the shelf off New Jersey (40°N, 70°W). Citharichthys cornutus measured 17.2–81.3 mm standard length (SL); males (20.0–79.1 mm SL) and females (28.0–81.3 mm SL) attain similar sizes (sex could not be determined for fish <20 mm SL). Males reach nearly 100% maturity at ≥60 mm SL. The smallest mature females are 41.5 mm SL, and by 55.1 mm SL virtually all are mature. Juveniles are found with adults on the outer shelf. Only 214 C. gymnorhinus were located in 42 different field collections (35–201 m, with 90% between 61 and 120 m) off the east coast of the United States, Bahamas, and eastern Caribbean Sea. Adults are found as far north as the shelf off Cape Hatteras, NC (35°N, 75°W). This diminutive species (to 52.4 mm SL) is among the smallest flatfishes but males (n=131; 20.3–52.4 mm SL) attain a slightly larger maximum size than that of females (n=58; 26.2–48.0 mm SL). Males begin to mature between 29 and 35 mm SL and reach 100% maturity by 35–40 mm SL. Some females are mature at 29 mm SL, and all females >35.1 mm SL are mature. Overlooked specimens in museum collections and literature enabled us to correct long-standing inaccuracies in northern distributional limits that appear in contemporary literature and electronic data bases for these species. Associated locality-data for these specimens allow for proper evaluation of distributional information for these species in relation to hypotheses regarding shifts in species ranges due to climate change effects.

Description of early life history stages of the northern sculpin (Icelinus borealis Gilbert) (Teleostei: Cottidae)

Larvae of the genus Icelinus are collected more frequently than any other sculpin larvae in ichthyoplankton surveys in the Gulf of Alaska and Bering Sea, and larvae of the northern sculpin (Icelinus borealis) are commonly found in the ichthyofauna in both regions. Northern sculpin are geographically isolated north of the Aleutian Islands, Alaska, which allows for a definitive description of its early life history development in the Bering Sea. A combination of morphological characters, pigmentation, preopercular spine pattern, meristic counts, and squamation in later developmental stages is essential to identify Icelinus to the species level. Larvae of northern sculpin have 35–36 myomeres, pelvic fins with one spine and two rays, a bony preopercular shelf, four preopercular spines, 3–14 irregular postanal ventral melanophores, few, if any, melanophores ventrally on the gut, and in larger specimens, two rows of ctenoid scales directly beneath the dorsal fins extending onto the caudal peduncle. The taxonomic characters of the larvae of northern sculpin in this study may help differentiate northern sculpin larvae from its congeners, and other sympatric sculpin larvae, and further aid in solving complex systematic relationships within the family Cottidae.
