IIRSA: outro passo na pilhagem, exploração e (des) integração dos povos e territórios sul-americanos

La llamada Iniciativa para la Integración de Infraestructura Regional Suramericana (IIRSA) es un acuerdo multinacional celebrado entre los 12 países de América del Sur desde el año 2000, materializado a través de 10 ejes de comercialización orientados a la construcción de varios proyectos de infraestructura, que incluye la construcción de una enorme red de energía, de comunicación y transporte. Estos proyectos han sido financiados principalmente por los organismos multilaterales (BID, CAF, FONPLATA) profundizando la dependencia económica y política de los países involucrados, en especial mediante el aumento de la deuda externa, las empresas transnacionales garantizarán la infraestructura necesaria para la explotación más acentuada de nuestros recursos naturales y de la mano de obra barata, asegurando el abastecimiento de sus mercados. En este sentido, el discurso de crecimiento económico regional creará los mecanismos necesarios para la reproducción ampliada del sistema capitalista, mediante la promoción de la liberalización de los mercados internacionales, tales como intenta los Estados Unidos a través del Área de Libre Comercio de las Américas. En realidad, es un Desarrollo Regional de los países del Norte, un plan estratégico de ordenamiento territorial construido por transnacionales y dictado por el imperialismo de Norteamérica. Bajo la dirección del gobierno de Brasil ha sido implementado sigilosamente, para que los jefes de Estado, sin nombrarlo, ejecuten sus planes de desarrollo como parte de esta tan evidente estrategia de saqueo, entusiasmados y convencidos de que serán generosamente recompensados. Proclaman e inauguran proyectos de infraestructura que las empresas multinacionales y transnacionales consideran indispensables para el saqueo de los recursos naturales que aún quedan, después de cinco siglos de explotación continua de América Latina. En este sentido, nuestra investigación se volvió hacia el análisis de lo sector energético de lo Eje Perú-Brasil-Bolivia, por considerarlo de suma importancia para el mantenimiento de la explotación y consolidación hegemónica de las corporaciones multinacionales en América Latina

A produção do Departamento de Imprensa e Propaganda (DIP) em acervos norte-americanos: estudo de caso

A ação do DIP tem recebido particular atenção, sobretudo quando se trata de evidenciar o caráter repressor e controlador que o órgão de fato exerceu. Menor ênfase tem sido dada a sua ação como editor e financiador de obras favoráveis ao regime: no mais das vezes, não se vai além da citação de uma lista de títulos favoráveis ao regime, que comprovam o investimento na imagem do chefe. Pesquisa realizada em dois acervos norte-americanos permitiu manipular um rol significativo de obras publicadas no período, as quais apontam para uma trama complexa entre autores, editores e gráficas. Além disso, a presença desse material no exterior indica os esforços do regime para atingir uma audiência internacional.

Composição ictiofaunística e estratégias reprodutivas de quatro espécies de peixes nativos da Bacia Hidrográfica Piranhas - Assu, Rio Grande do Norte

This study focuses on the fish fauna composition and reproductive strategies of four native fish species in relation to environmental variables of the Piranhas-Assu hydrographic basin of the Caatinga biome, Rio Grande do Norte, Brazil. Fish and environmental data were collected monthly during the period September 2008 to February 2010, in the Marechal Dutra reservoir and River Acauã a tributary of Piranhas- Assu. The fish were measured, weighed and dissected, and the gonads were removed, weighed and examined macroscopically for identification and determination of gonad maturation stages. The results of this work generated seven articles. The first article is about the fish fauna composition of the Piranhas-Assu hydrographic basin, Rio Grande do Norte. The 602 fish samples captured were distributed in four orders (Characiformes, Perciformes, Siluriformes and Synbranchiformes), 11 families and 22 species, of which 17 are endemic to the Caatinga ecoregion. The order Characiformes was more representative followed by Perciformes, Siluriformes and Synbranchiformes. The second article is about the length-weight relationship and growth of seven native fish species Crenicichla menezesi, Cichlasoma orientale, Triportheus angulatus, Psectrogaster rhomboides, Pimelodella gracilis, Prochilodus brevis and Leporinus piau from a semiarid Brazilian reservoir. The third article is about the reproductive aspects of Crenicichla menezesi. Males were larger, heavier and with a slight predominance as compared to females. Four stages of gonadal development were characterized, being immature, maturing, mature and spent. The females reached sexual maturity earlier than males, with an average fecundity of 398 oocytes per batch. The spawning was partial with a long reproductive period. The fourth article deals with the reproductive strategy of Leporinus piau a neotropical freshwater fish in semi-arid region of Brazil. The population of L. piau (n = 211) showed a slight predominance of males (55%), with larger and heavier females. The males matured earlier than the females. This species presented total spawning, with an average fecundity of 55,000 mature oocytes. Rainfall and concentration of dissolved oxygen acted as influential factors during the spawning season. L. piau shows a seasonal reproductive strategy. The fifth article is related to the morphometric-meristic characteristics and reproductive aspects of freshwater sardine, Triportheus angulatus from River Acauã of the Caatinga biome. There was a predominance of larger females, reaching first maturation before males. There was total spawning during the rainy period of the region. The sixth article reports on the reproductive strategy of Psectrogaster rhomboides. The sex ratio was 1M: 1F, with negative allometric growth. Males reached sexual maturity earlier than females Females and males showed four stages of gonadal development and spawned during the rainy season. The fecundity was low and this species presented total spawning. The seventh article reports on the dynamics of territorial behavior of Crenicichla menezesi. Ten agonistic behaviors displayed by the males were observed: frontal and lateral threat, chasing, circular chasing, perpendicular, lateral and mouth attacks, escape, parallel positioning and stationary. The formation of four social groups was observed among males: without interaction; interaction with submission and escape; with frontal and lateral agonistic interactions. In social interactions between males and females, it was observed that the larger males interacted more among themselves and with the larger females. The large male established its territory and the two small males along with the small female were excluded from the other groups. These studies clarified the fish fauna composition and reproductive strategies of four native species Crenicichla menezesi, Leporinus piau, Triportheus angulatus and Psectrogaster rhomboides of the Piranhas- Assu hydrographic basin of the Caatinga biome, Rio Grande do Norte, Brazil.

De vilarejo a cidade: identidade de lugar de moradores nativos de Tibau do Sul-RN

This study aimed to analyze some indicators of the restructuring process of place identity of natives resident in Tibau do Sul, a coastal town in the state of Rio Grande do Norte state, in relation to changes occurring in this locale in the last few decades. The concept of place identity a complex psychological structure in constant process of restructuring stresses the focus of this analysis on the aspects referring to the relationships of people with their physical and social environment throughout the transition process from the former village of fishermen and peasant farmers to the current growing town. Interviews with insider informants on local history were carried out as a preliminary step to getting in touch with the native participants. In total, 29 native local residents were interviewed, according to a wide range of personal and professional roles, focusing on their cognitions in regard to their past and present relationships with this context, as well as those related to expectancy for the future. The analysis focused both on the elements of distinctiveness, continuity, self-esteem and self-efficacy, and on how each of them have been valued (positive or negative). The participants evaluations of themselves and of the locale, as well as their distinctions in relation to others (people and places) were, in general, very positive. Many elements of group and place continuity, and the possibility of the satisfaction of their needs were highlighted positively, especially comparing to similar situations in the past. The development of the town, related to tourism as well as to other former economic activities, seemed to contribute to the restructuring process of place identity in a way of achieving desirable states for its structure. The broadening of the analysis to consider a wider spatial and temporal context, however, shows that such positive evaluation can be said to hinder some coping strategies of local residents faced with unsustainable economic activities, oftentimes handled to favor a minority of the population
