A DESCRIPTIVE ANALYSIS OF THE SEASONAL VARIATION OF PHYSICAL OCEANOGRAPHIC CHARACTERISTICS IN THE NORTHERN REGION OF THE TODOS OS SANTOS BAY (BAHIA, BRAZIL)

The results obtained in the August and December 2003, August 2004 and January 2005 oceanographic campaigns in the northern region of the Todos os Santos Bay (lat. 12 degrees 44.5`S; long. 038 degrees 35.00`W) between the Madre de Deus and Mare islands are analyzed. Instruments of continuous and discrete samplings were used to measure hydrographic properties currents and tides. The water mass of the northern region of the bay is forced by semidiurnal and mesotides of form number 0.08 and the lunar component M(2) height was estimated at 91cm. The time series of the surface currents indicated movements in the N/S direction, forced by the tide with maximum magnitudes of 0.73 m.s(-1) on the December 2003 campaign. However, in August 2004 the currents were dominated by the wind stress forcing, with a maximum speed of 1.85 m.s(-1) and SE direction. Near the bottom, the influence of the tide is not as evident, with a decrease in intensity due to internal and bottom friction, with a maximum velocity of 0.17 m.s(-1). The thermal and haline structures were weakly horizontally, as well as vertically stratified, with extreme values varying in the intervals 23 degrees C (August, 2004) to 28 degrees C (December, 2003) and 31.0 psu (August, 2003) to 36.0 psu (December, 2003), respectively. Some conclusions may be drawn from these results: i) The signs of the dilution of the fresh water discharges of the Caipe, Mataripe and Sao Paulo rivers in the region under the influence of the RLAM were observed only during the winter periods, but in the summer the region was flooded by waters of oceanic origin and the salinities above 36.0 indicated TW mass intrusion; ii) The N-S circulation near the RLAM is strongly dominated by the tide, and the importance of the M(2) component was unequivocal, however, the E-W component presented some tidal modulation away from abrupt bottom topographical changes, and iii) The residual series, calculated as the difference between the original and modeled, is about 1/4 of the original and confirmed its semidiurnal character.

ICHTHYOPLANKTON DISTRIBUTION AND ABUNDANCE IN THE NORTHERN TODOS OS SANTOS AND CAMAMU BAYS, BAHIA STATE - BRAZIL

The occurrence, distribution and abundance of ichthyoplankton in Todos os Santos and Camamu Bays were analyzed based on four samplings (winter 2003, summer 2003, winter 2004 and summer 2005). Samples were obtained by surface horizontal hauls, using a 200-mu m mesh conical-cylinder plankton net. The distribution and abundance of eggs indicate a remarkable seasonal and annual variation of spawning activity in the region, especially when the two summer campaigns are compared. In summer 2003 the highest quantitative values were recorded, especially for Camamu, where the maximum reached 106.56 eggs.m(-3), with an overall average of 43.46 eggs.m(-3) for the two areas. In summer 2005 values were relatively low, the overall average being 3.49 eggs.m(-3). The larval taxonomic composition is characterized by the predominance of gobiids, with small variation from summer to winter. Considering all the campaigns and samplings undertaken in both areas, larvae of 11 families were identified: Engraulidae, Clupeidae, Mugilidae, Atherinopsidae, Hemiramphidae, Syngnathidae, Blenniidae, Carangidae, Gobiidae, Achiridae and Tetraodontidae.

Todos os filmes estrangeiros

O artigo toma as figuras da legenda e da dublagem como pontos de partida para a exploração das várias formas de estrangeirice no audiovisual. Tais figuras são apenas as marcas mais visíveis e impositivas da maneira como os filmes envolvem questões relacionadas com a diferença, a alteridade e a tradução. Em seguida, o artigo também discute o que pode ser um filme estrangeiro no contexto da globalização e da internacionalização da produção cinematográfica. Enfim, ele invoca o conceito de «cinema com sotaque», ou seja, o cinema criado ao mesmo tempo nos interstícios das formações sociais e das práticas cinematográficas, especialmente nas comunidades exílicas e em situações de diáspora.

Comunicação e ação política no contínuo mediático: Luhmann contra Habermas. E nós contra todos

A política para Jürgen Habermas se faz com a formação de consciências e com o investimento na linguagem, no falar cotidiano, na relação intersubjetiva. Já para Niklas Luhmann, a política se faz por si mesma, e a opinião pública não tem relação com a opinião pessoal. Não adianta investir na linguagem, porque ela é pré-social, está além dos sujeitos, nenhuma democratização pode sair daí. Mas as propostas dos dois pensadores mostram-se insuficientes para a atualidade, com suas altas tecnologias comunicacionais, pois nenhum dos modelos dá uma resposta animadora para a questão das redes, nenhuma delas visualiza um espaço mediático próprio fazendo a mediação dos sistemas, nenhuma delas dá elementos para a construção de uma teoria da comunicação tecnologicamente avançada.

Catch rates of artisanal fisheries targeting Dasyatis guttata (Bloch & Schneider, 1801) in Todos os Santos Bay, northeastern Brazil

Dasyatis guttata has been target of artisanal fisheries in the coast of Bahia (Northeast Brazil) mainly by “arraieira” (gillnet) and “grozeira” (bottom long-line), but until now there is no stock assessment study. One of the important data for this knowledge is reliable indices of abundance. The aims of the present work are to: (1) estimate the best predictor for relative abundance (catch-per-unit-of-effort, CPUE), examining whether catch (production – kg) was related to: soak time of the gear, size of the gillnet or number of hooks, applying generalized linear model (GLM); (2) estimate the annual CPUE (kg/hooks and kg/m) averaged by gear; and (3) assess the temporal CPUE variance. Based on monthly sampling between January 2012 and January 2013, 222 landings by grozeira and 76 by arraiaiera were recorded in the two landing sites in Todos os Santos Bay, Bahia. A total of 14,550 kg (average = 44 kg/month) of D. guttata was captured. Models for both gears were highly significant (P < 0.0001). The analysis indicated that the most appropriate variable for CPUE analysis was the size of the gillnet (P < 0.001) and the number of hooks (P < 0.0001). Soak time of the gear was not significant for both gears (P = 0.4). High residual deviance expresses the complexity of the relations between ecosystem factors and other fisheries factors affecting relative abundance, which were not considered in this study. The average CPUE by grozeira was 6.39 kg/100 hooks ± 8.89 and by arraieira, 1.47 kg/100 m ± 1.66 over the year. Kruskal-Wallis test showed effect of the month on the mean grozeira CPUE (P = <0.001), but no effect (P = 0.096) on the mean arraieira CPUE. Grozeira CPUE values were highest in December and March, and lowest between May to August

Espacios de nadie y de todos: Territorio y sociedad en la frontera andalusí al norte del Tajo extremeño (Siglos VIII-XI)

[ES]Entre mediados del siglo VIII y mediados del siglo XII, el espacio comprendido entre el Sistema Central y el río Tajo en su parte extremeña ejerció como confín territorial de al- Andalus. A lo largo de todo este tiempo se sucedieron distintas fases en las que la frontera fluctuó según vinieran los aires cristianos del norte o islámicos del sur. Ello provocaría que estos territorios actuaran con relativa autonomía en muchos momentos de su historia andalusí y que se convirtieran en zonas donde confluían gentes de toda condición social y religiosa. En el presente trabajo tratamos de vislumbrar las dinámicas territoriales y sociales que se dieron en aquella región hasta finales del siglo XI, cuando se produjeron las conquistas cristianas de las ciudades islámicas más importantes de la frontera. [EN] The geographical area between the Spanish Central System and the part of the Tagus passing through Extremadura served as the boundary of the al-Andalus from the 8th to the 12th century. The boundary had different phases that fluctuated according to the influence exercised by the northern Christians or southern Muslims. This allowed these territories to have relative autonomy during its Andalusian history and turned them into zones where people from different social and religious background converged. The aim of this paper is to analyse the territorial and social dynamics of this area until the end of the 11th century, when the Christians conquered the most important Islamic towns of the borderland.
