A partir del buidatge exhaustiu dels fulls de subhasta del peix i de les fitxes tècniques de les embarcacions de la Confraria del Port de Llançà, es fa una anàlisi cronològica qualitativa i quantitativa dels darrers vint anys de pesca. La flota, inicialment constituïda per barques d'arrossegament i de pesca artesanal (palangre petit i tresmail), ha anat evolucionant, i ha quedat bàsicament constituïda actualment pel ròssec i el palangre de fons, que ha substituit progressivament la pesca artesanal. Les pesqueries, notablement multiespecífiques els primers anys, van donar pas, bàsicament amb la incorporació del radar, a una pesca molt més selectiva, dominada essencialment per la captura de lluç entre els anys 1980 i 1985. La progressiva incorporació del palangre de fons fa que a partir del 1986 es tendeixi novament cap a una captura més multiespecífica, perd amb canvis qualitatius importants en la composició d'espècies capturades en relació amb els primers anys

Després de les dues crisis de la fi de segle passat -la fil·loxera i la competencia dels cereals ultramarins-, el procés de canvi de l' agricultura gironina es va accelerar, però el seu procés real de modernització no es va produir fins als anys seixanta, amb el final del model agrari lligat a l'autoconsum. A la mecanització del camp va seguir la del món de la pesca, especialitzada i concentrada en uns quants ports -els millor dotats i els mes ben comunicats- i convertida en una dedicació menys arriscada i mes regular, pero també menys sàvia

The employees' partlclpation in the cultural transltIon process occurred in Companhia Siderúrgica de Tubarão (CST) was helpful in the identification of the group of measures that started to be managed in order to be established in the run of the control assumption. The company, in order to acquire proper features, had to change prior values, behaviors and identities through strategies shared by ali the organization members, thus, creating a new culture. The CST was seen as a company controlling and coordinating a group of people. It counted on vertical hierarchical leveis, departments and authority relations. It was neve r taken into account that the company could have its own personality, like each person that worked there. Before getting through this cultural transition process, that extremely changed its values, the company had a dominating culture, with a centralized administration. This way, it influenced the conduct of ali its members, in a controlling environment. When the company realized the necessity of investments in cultural changing programs, in order to eliminate the pathologies and disfunctions that were hitting its business structure, causing damage to productivity and to the quality of the results, it condensed energies in one direction implementing the participation of ali its leaderships as implementing and multiplier elements to orientate and facilitate the achievement of its goals. Trying to understand better the influences suffered by the changes brought by globalization and privatization, some theorical and operational concepts of culture and identity were developed in this study, mainly in the first chapters. In the research extension, several aspects of this complex anthropological and sociological concept of culture were managed, such as affectiveness, cognitive process, valuation process and everything that could be related to or that give elligibility to this concept and to the phenomenon this concept will consist in.

The purpose of this study is to analyze the effects of the productive reorganizations occurred at Companhia Siderúrgica de Tubarão (located in the State of Espirito Santo, Brazil), during the 90¿s, regarding the professional qualification of its work force.The purpose is to describe and to explain the process of changes effected in the productive structure of the company and its connections with the changes that took place in the siderurgy in general. It is against the context of the deep changes - technological, managerial, of productive processes, in logistics, etc. occurred in the last decade that the problems of professional qualification of CST's work force are focused. To explore it, the supported hypothesis is that the productive reorganizations CST passed during the 90's had imposed the need of a broader qualification of its work force, in terms of formal education (upper, average, basic level), and in terms of technical abilities required by the production.The research development is anchored in a methodology that combines the following methods: bibliographical, documental and fieldwork, with a qualitative approach, in the scope of case study.

Esta monografia é um estudo de caso que objetiva uma experiência educacional fracassada, realizada em Tubarão, Santa Catarina, no periodo de 1972 a 1978, pelo Centro Intercolegial Integrado de Tubarão - CICIT. Tenta investigar as razões do fracasso, a partir da suposição de que, coexistindo com a modernidade, há um forte componente de cultura retrógrada, atuando como força de resistência às tentativas de mudança social, desde que ponha em risco os interesses das camadas conservadoras. Faz a análise das condições históricas e sociais de implantação do CICIT, que se inspirou na concepção iluminista de restauração social,através da educação, e de sua extinção. Examina os limites da proposta de inovação educacional, tentada dentro de um contexto social conservador. Observa que a proposta continha contradições dificeis de ser superadas no campo operacional, pelo fato de nao prever a resistência, em cadeia, das correntes conservadoras que acabaram a ela se opondo, em princípio. A inovação pretendida refletia um posicionamento próprio da classe média em ascensão no inicio da década de 70, quando apostava no sucesso do projeto de desenvolvimento do capitalismo brasileiro, gerenciado pelos tecnocratas, e tutelado pela corporação militar em crescente politização. Várias manobras desenvolvidas "pelas forças ocultas" locais contra o CICIT são descobertas mediante um processo de levantamento de dados onde conversas informais se revelaram mais eficientes que os métodos convencionais de coleta de informação. Dá importância destacada a depoimentos de pessoas que estiveram presentes no dia a dia da experiência do CICIT. Epistemologicamente, opta pelo ponto de vista dos que fracassaram frente à resistência das forças conservadoras. Supõe que a verdade dos vencidos corresponde melhor à realidade objetiva dos fatos. Os vencedores, geralmente, arbitram as "verdades" que melhor correspondam a seus interesses. As análises desenvolvidas conduzem à conclusão ampla de que o poder de reação das "forças ocultas" - para as quais qualquer mudança é sempre entendida como ameaça - foi maior que o poder de inovação do CICIT. Esta pesquisa, longe de esgotar o assunto, deixa ver que outras análises deveriam ser feitas a respeito.

A pesca artesanal, assim como a agricultura, constitui um objeto de estudo complexo, sendo influenciada por determinantes ambientais, culturais, sócio-econômicas e técnico-produtivas. A combinação destes determinantes com as variáveis tempo e espaço, produz, para cada localidade, uma diversidade de formas através das quais os pescadores artesanais buscam interagir com a natureza e extrair dela seu sustento. Estas constatações motivaram uma dissertação de mestrado, realizada em uma tradicional comunidade pesqueira do estuário da Lagoa dos Patos, no estado do Rio Grande do Sul, e cujos principais resultados buscaremos apresentar neste artigo. A utilização de uma abordagem sistêmica, através de uma adaptação conceitual e metodológica das teorias de evolução e diferenciação dos sistemas agrários, permitiu identificar a variabilidade existente nesta comunidade, em termos de tipos de pescadores e sistemas de produção na pesca, por eles praticados. Foi possível, partindo de categorias utilizadas pelos próprios pescadores, identificar cinco diferentes tipos, que interagem, através de relações de trabalho ou em função da estrutura de capital da qual dispõe, na implementação de três sistemas de produção na pesca distintos. Ao assumir esta variabilidade interna ao grupo social, a pesquisa pode revelar a dinâmica de diferenciação social proporcionada pelo impacto desigual de fatores como as políticas sociais e as políticas públicas voltadas ao fomento da produção, em inter-relação com a eficiência técnica e econômica dos diferentes sistemas de produção na pesca.

This work presents a reflection on possibilities and boundaries of consolidation and expansion of human settlements characterized as traditional communities that are located within protected areas, using as study reference the State Sustainable Development Reserve Ponta do Tubarão, at Rio Grande do Norte state. The main topics highlight the conflict between the right to housing and the prevalence of fundamental rights of traditional populations, opposed to the diffuse right to environment, according to the regulatory framework of the Brazilian Urban and Environmental Policies. At the same time that these settlements, historically built, are substantiated by the principles of recognition of rights to traditional populations, they are in a condition of complexity to the resolution of conflicts in its urban dimension and lead to an impairment of natural sites. This work questions how the instruments of land use and occupation are defined and relate to environmental planning, especially considering that the settlements are located in Permanent Preservation Areas (APP). It aims to further the discussion of the urban dimension in settlements, characterizing its formation and growth process, to identify the gaps and convergences between the Urban and Environmental Policy, under the foundations of a socio-environmental approach. The results spotlights the conflicts between occupation and natural areas, inferring that the definition of Urban Policies instruments and its integration with Environmental Policies instruments account for essential and priority actions to the achievement to the rights to a sustainable city, as determined in the Cities Statute and environmental protection goals, defined for the Conservation Units

Knowledge of the environmental factors influence on the spatial-temporal variation of fishes is important to fisheries management and conservation. Thus, the aim of this work was to analyze the influence of the abiotical factors on the spatial-temporal distribution of Paralonchurus brasiliensis (Pisces, Sciaenidae) caught by-catch with the shrimp fishing of Ubatuba and Caraguatatuba regions, north coast of São Paulo State. The fishes were captured every month from January to December 2002. Samples were collected by otter trawl at 5, 10, 15, 20, 25, 30 and 35m depths. The temperatures (surface and bottom), salinities (surface and bottom), sediment features and organic matters were verified for each depth. During all period of the study 12.642 specimens of P. brasiliensis were captured at Ubatuba and 17.166 at Caraguatatuba, which totalized the biomass of 267 for the first and 339kg for the other region. The females outnumbered males in fish population. The greatest values of biomass and number of individuals were registered at the summer and autumn seasons, while the lowest values were observed at the winter and spring seasons. The greatest abundances were found from 15 to 25m depth. In this study, it was verified that P. brasiliensis is a coastal waters associate species. The spatialtemporal distribution of P. brasiliensis is affected by intrusion of SACW and depth for the coastal region and by depth and sediment in sheltered areas such as Caraguatatuba

The species Dasyatis marianae inhabits coastal areas associated with coral reefs, considered endemic to the northeast of Brazil, occurring from the State of Maranhão to the south of Bahia. Specimens of this species are commonly sighted by divers and fishermen in the area of Maracajaú reefs, a complex reef that is part of the Environmental Protection Area of Coral Reefs (EPACR), which was developed in this study about the ecology and biology of the D. marianae, in order to characterize aspects of population structure in the area of the reef complex of Parracho de Maracajaú. We analyzed 120 specimens caught by artisanal fishing site of the size, weight, sex, stage of maturity and stomach contents. Most subjects were adult males (1.7:1) and was more abundant for rays with lengths between 25 and 29cm of LD, where females reach larger sizes, a feature common to other rays. The largest specimens were captured in the area of seagrass, which is preferred for the species. The distribution of species in the area showed an ontogenetic and sexual segregation, where the youthful occur near the beach, which is a likely area for nursery and growth of the adult females prevail in the seagrass, which apparently has a high prey availability, and Adult males are more distant, a higher proportion occurring in outlying areas, suggesting a habit more exploratory than the females. The evaluation of the reproductive system indicated 3 reproductive cycles per year, one young per pregnancy, and showed that the mature males were smaller than females. The cubs of D. marianae size at birth 12 to 15cm LD. As for diet, the species was characterized as carnivorous crustacean specialist. The performance of visual censuses in different localities allowed to evaluate the density of D. marianae in different environments of the complex. The species occurs in greater numbers in seagrass, environment very important for the conservation of the species. 100 individuals of D. marianae marked in reef complex area enrolled in a recapture rate of 3%. Some behavioral aspects were evaluated, as diurnal pattern of activity, interaction with cleaning and fish Pomacanthus paru followers as Lutjanus analis and Carangoides bartholomaei. Overall, much of the information obtained should be used for management of the species
