O cangaço no cordel e a constituição de uma identidade regionalista pelo migrante nordestino (1950-1980)

Neste trabalho, a partir da recorrência à literatura de cordel como fonte histórica, será apresentada de que forma a reprodução da temática do cangaço nesses folhetos permitem que os migrantes nordestinos constituam uma identidade regionalista baseada no apego aos valores tradicionais da sua região natal. Dentro desse contexto, relacionamos o processo migratório dos nordestinos para as grandes metrópoles situadas no Sudeste, sobretudo Rio de Janeiro e São Paulo, com a difusão e recepção dos cordéis nesses estados entre as décadas de 1950 e 1980. No que concerne a abordagem do cangaço nos versos da literatura de cordel, na qual atribui aos cangaceiros o papel de símbolos regionais, serão pontuadas as principais estratégias adotadas pelos cordelistas que possibilitam a identificação e a empatia dos migrantes vindos do Nordeste com os personagens do cangaço narrados nos folhetos, contribuindo para um maior estreitamento entre Nordeste e nordestino. Nesse sentido, vale ressaltar a ressignificação da imagem dos cangaceiros, deslocando sua representação de homens cruéis e bárbaros para a reprodução de heróis-vilãos, isto é, protagonistas de personalidades ambíguas e contraditórias

Literature review for a resource characterization of Cape Romain National Wildlife Refuge

Through research aimed at understanding the coastal environment, surveys designed to help manage the resource, and national programs to monitor environmental condition, we see a picture of a dynamic ecosystem that is Cape Romain National Wildlife Refuge (CRNWR). Currently, there are efforts underway to protect threatened species; monitor fish populations; and quantify the biological, physical, and chemical characteristics of this environment. The potential impacts to this system are just now being understood as ecological responses to human modification are observed and explained. As a starting point, this document compiles existing information about Cape Romain NWR in five topic areas and addresses the potential impacts to the Refuge. This review is intended to serve as a stepping stone to developing a research agenda in support of management of the Refuge. There are various sources of information on which to build a framework for monitoring conditions and detecting change to this environment. For instance, information on basic ecological function in estuarine environments has evolved over several decades. Long-term surveys of Southeast fisheries exist, as well as shellfish and sediment contaminants data from estuaries. Environmental monitoring and biological surveys at the Refuge continue. Recently, studies that examine the impacts to similar coastal habitats have been undertaken. This document puts past studies and ongoing work in context for Refuge managers and researchers. This report recommends that the next phase of this resource characterization focus on: • compiling relevant tabular and spatial data, as identified here, into a Geographic Information System (GIS) framework • assessing the abundance and diversity of fisheries utilizing CRNWR • delineating additional data layers, such as intertidal habitats and subtidal clam beds, from low-level aerial photography, hard copy maps, and other sources • continued inventories of plant and animal species dependent on the Refuge • monitoring physical and chemical environmental parameters using the methodology employed at National Estuarine Research Reserve System (NERRS) and other coastal sites, where appropriate • further definition of the potential risks to the Refuge and preparing responses to likely impacts.

Testicular development in migrant and spawning bluefin tuna (Thunnus thynnus (L.)) from the eastern Atlantic and Mediterranean

Testis histological structure was studied in bluefin tuna (Thunnus thynnus) from the eastern Atlantic and Mediterranean during the reproductive season (from late April to early June). Testicular maturation was investigated by comparing samples from bluefin tuna caught on their eastward reproductive migration off Barbate (Strait of Gibraltar area) with samples of bluefin tuna fished in spawning grounds around the Balearic Islands. Histological evaluations of cross sections showed that the testis consists of two structurally different regions, an outer proliferative region where germ cells develop synchronously in cysts, and a central region made up of a well-developed system of ducts that convey the spermatozoa produced in the proliferative region to the main sperm duct. Ultrastructural features of the different stages of the male germ cell line are very similar to those described in other teleost species. The bluefin tuna testis is of the unrestricted spermatogonial testicular type, where primary spermatogonia are present all along the germinative portion of the lobules. All stages of spermatogenesis were present in the gonad tissue of migrant and spawning bluefin tuna, although spermatids were more abundant in spawning fish. The testis size was found to increase by a factor of four (on average) during migration to the Mediterranean spawning grounds, whereas the fat bodies (mesenteric lipid stores associated with the gonads) became reduced to half their weight, and the liver mass did not change significantly with sexual maturation. Linear regression analysis of the pooled data of migrant and spawning bluefin tuna revealed a significant negative correlation between the gonad index (IG) and the fat tissue index (IF), and a weaker positive correlation between the gonad index (IG) and the liver index (IL). Our analyses indicate that the liver does not play a significant role in the storage of lipids and that mesenteric lipid reserves constitute an important energy source for gametogenesis in bluefin tuna.

Scoping study on migrant fishers and transboundary fishing in the Bay of Bengal

This study assesses the issue of migratory and transboundary fishing. It explores working conditions on fishing vessels operating outside national waters together with issues pertaining to rights and extent of use of legal and illegal foreign labour. The report also provides recommendations for action and further research.
