Estimativa populacional e uso do hábitat do boto-cinza (Sotalia guianensis) no litoral sul do Rio Grande do Norte

Four areas are known as of frequent usage by Guiana dolphins (Sotalia guianensis) in the south coast of Rio Grande do Norte state, northeast Brazil: Tabatinga, Pipa, Lagoa de Guaraíras and Baia Formosa. This extension of 40 km of shoreline is under increasing anthropogenic impacts due to continuous development of the coastal areas and vessel traffic. The objective of this study was to investigate aspects of population biology and habitat use of the population of Sotalia guianensis in the south coast of Rio Grande do Norte. It was applied the photo-identification technique and posterior methods of capture-recapture for population estimation (POPAN extension in MARK). The distribution, movement and site fidelity of the dolphins were analyzed trough the geographic information system (GIS) and group characteristics and behavior trough non-parametric statistics. Field work was conducted on board a 10m motor vessel from March 2008 to March 2009. Photo-identification effort was 329h with 113h of direct observation of the dolphins. The population estimatives for each area: Tabatinga: 75 (63-92); Pipa 105 (88-129); Lagoa de Guaraíras: 27 (18-54) e Baia Formosa: 112 (89-129) individuals. Total population estimative was: 223 (192 a 297). High site fidelity was detected for only part of the population (<15%) as low site fidelity and transients individuals were also detected (>20%). It was observed frequent movements between Tabatinga, Lagoa de Guaraíras and Pipa, but not Baía Formosa. This suggests a division in two communities along this shore extension: one in Pipa and other in Baía Formosa. Group size was small, most groups with up to 10 dolphins. The areas were use intensively, only in Lagoa de Guaraíras dolphins were not seen in all field trips. Lagoa de Guaraíras is an area used by small groups exclusively for foraging. In Tabatinga and Pipa dolphins concentrated close to the shore, in the inner sector of the area and the main activity is also foraging. Significant larger groups were seen in socializing behavior but there was no difference in group size between the inner and external sectors of the area. The presence of calves and juveniles were significant greater in the inner areas of Tabatinga and Pipa, confirming the hypothesis that these beaches are also used for parental care. In Baia Formosa dolphins concentrated in the outer sector and foraging was also predominant. Significant larger groups were seen in the outer sector, mainly engaged in mixed behaviors of travel/foraging, possibly in some kind of group foraging. Calves and juveniles were significant more present in the outer sector where group size was also larger. In general there was no difference in area usage and period of the day. Sotalia guianensis has characteristics that make the species vulnerable to human activities such as small population concentrated in patches of suitable habitats restrict to coastal areas. We hope that this study bring new information for the species and help for the adequate management of the area in order to assure the presence of the dolphins as well as its behavior pattern and gene flow betweencommunities.

A Praça André de Albuquerque, Natal/RN, na visão de seus frequentadores

The study offers a global and interpretative view of the person-environment inter-action at André de Albuquerque Plaza, in Natal, RN, according to a descriptive-exploratory approach that aimed at learning about the space converted into place, as it is perceived and experienced by users, who attribute meaning to it. The main objective was to critically analyze the relationship person-plaza, based on data collected about users perception, utilization and ascribed meaning. I have employed an Environmental Psychology multi-method approach, including informal observations, interactive poster session, videotaping and interviews. The results indicated that the plaza, besides being a passage point, is also a spot of urban convergence for several groups, particularly taxi drivers, flanelinhas, skate boarders and students. In regard to the perception of the place, an overall positive evaluation of the plaza was verified, since people perceive selectively what interests them. In terms of usage, different groups of users presented diverse patterns of utilization, also observed in the attributed meanings. The plaza is a work place for taxi drivers and flanelinhas and a sports arena for the skate boarders, with a practical meaning for both groups. For students and other users it is a place for meeting and leisure, revealing a stronger affective quality, responsible for feelings of well being, tranquility and relaxation. The data so obtained could contribute for future government projects of intervention in those spaces, aiming at its preservation as an open spot among the concrete of city buildings, offering better quality of life, not only for today, but also for future generations

Entre a hegemonia e a polissemia: a Política de Educação e Desenvolvimento para o SUS no contexto do Brasil contemporâneo

The proposal of the Unified Health System Policy (SUS) has been considered one of the most democratic public policies in Brazil. In spite of this, its implementation in a context of social inequalities has demanded significant efforts. From a socio-constructionist perspective on social psychology, the study focused on the National Policy for Permanent Education in Health for the Unified Health System (SUS), launched by the Brazilian government in 2004, as an additional effort to improve practices and accomplish the effective implementation of the principles and guidelines of the Policy. Considering the process of permanent interdependencies between these propositions and the socio-political and cultural context, the study aimed to identify the discursive constructions articulated in the National Policy for Permanent Education in Health for the Unified Health System (SUS) and how they fit into the existing power relations of ongoing Brazilian socio-political context. Subject positionings and action orientation offered to different social actors by these discursive constructions and the kind of practices allowed were also explored, as well as the implementation of the proposal in Rio Grande do Norte state and how this process was perceived by the people involved. The information produced by documental analyses, participant observation and interviews was analyzed as proposed by Institutional Ethnography. It evidenced the inter-relations between the practices of different social actors, the conditions available for those practices and the interests and power relations involved. Discontinuities on public policies in Brazil and the tendency to prioritize institutional and personal interests, in detriment of collective processes of social transformation, were some of obstacles highlighted by participants. The hegemony of the medical model and the individualistic and curative intervention practices that the model elicits were also emphasized as one of the drawbacks of the ongoing system. Facing these challenges, reflexivity and dialogism appear as strategies for a transformative action, making possible the denaturalization of ongoing practices, as well as the values and tenets supporting them

A articulação da instrumentalidade no exercício profissional do assistente social em Natal/RN

Presents the discussion of practical and social dimensions that comprise the instrumentality (formative; theoretical and intellectual; investigative; technical-instrumental; and ethical-political) Social Work from research in social and occupational areas in which they operate social workers in Natal in Rio Grande do Norte. Chapters expose positions, experiences and reality of the respondents and the theoretical constructs and analytical, to understand: the evaluation of the training process, relating the teaching practice, the role of knowledge and the importance of research in professional practice of social workers, the seizure of technical-instrumental dimension, articulating demands, duties, powers and instruments, as elements that comprise it, and finally the ethical-political dimension, discussing the challenges of ethics and materialization of the ethical-political in daily work. In this sense, the dissertation sought add to production and academic debate about the work of the social worker, as well as contribute to their own professional practice, revealing how professionals articulate the practical and social dimensions that comprise the instrumentality in their daily work

Prova automática de satisfatibilidade módulo teoria aplicada ao método B

Este trabalho apresenta uma extensão do provador haRVey destinada à verificação de obrigações de prova originadas de acordo com o método B. O método B de desenvolvimento de software abrange as fases de especificação, projeto e implementação do ciclo de vida do software. No contexto da verificação, destacam-se as ferramentas de prova Prioni, Z/EVES e Atelier-B/Click n Prove. Elas descrevem formalismos com suporte à checagem satisfatibilidade de fórmulas da teoria axiomática dos conjuntos, ou seja, podem ser aplicadas ao método B. A checagem de SMT consiste na checagem de satisfatibilidade de fórmulas da lógica de primeira-ordem livre de quantificadores dada uma teoria decidível. A abordagem de checagem de SMT implementada pelo provador automático de teoremas haRVey é apresentada, adotando-se a teoria dos vetores que não permite expressar todas as construções necessárias às especificações baseadas em conjuntos. Assim, para estender a checagem de SMT para teorias dos conjuntos destacam-se as teorias dos conjuntos de Zermelo-Frankel (ZFC) e de von Neumann-Bernays-Gödel (NBG). Tendo em vista que a abordagem de checagem de SMT implementada no haRVey requer uma teoria finita e pode ser estendida para as teorias nãodecidíveis, a teoria NBG apresenta-se como uma opção adequada para a expansão da capacidade dedutiva do haRVey à teoria dos conjuntos. Assim, através do mapeamento dos operadores de conjunto fornecidos pela linguagem B a classes da teoria NBG, obtem-se uma abordagem alternativa para a checagem de SMT aplicada ao método B

AutoWebS: um Ambiente para Modelagem e Geração Automática de ServiçosWeb Semânticos

Typically Web services contain only syntactic information that describes their interfaces. Due to the lack of semantic descriptions of the Web services, service composition becomes a difficult task. To solve this problem, Web services can exploit the use of ontologies for the semantic definition of service s interface, thus facilitating the automation of discovering, publication, mediation, invocation, and composition of services. However, ontology languages, such as OWL-S, have constructs that are not easy to understand, even for Web developers, and the existing tools that support their use contains many details that make them difficult to manipulate. This paper presents a MDD tool called AutoWebS (Automatic Generation of Semantic Web Services) to develop OWL-S semantic Web services. AutoWebS uses an approach based on UML profiles and model transformations for automatic generation of Web services and their semantic description. AutoWebS offers an environment that provides many features required to model, implement, compile, and deploy semantic Web services

Parâmetros urbanísticos para habitação de interesse social: uma análise crítica para as Rocas em Natal/RN

Through the comparative critical analysis of the demanded urbanistic parameters in the legislation and of the urbanistic index found in the Rocas neighbourhood, having as study object the already consolidated constructions of residential use, intended to demonstrate that the neighbourhood needes specific norms and that the limits established for recognition of Special Areas of Social Interest for the urbanistic legislation of the City of Natal would have to be reviewed and to be brought up to date, once they show occupations like the ones of the reffered neighbourhood. At a first moment, bibliographical revision and elaboration of the theoretical referencial had been made, , to analyze afterwards the urbanistic legislation for the neibourhood of Rocas, that determines relative parameters for the sizes of land lots, coefficients of exploitation, minimum taxes of occupation and retreat. Through a field research in the area, a study on the occupation description was done at first, characterization of the neibourhood through the study of the social-economic aspects, of the existing infrastructure in the place, environmental aspects, morphologic and tipolgic analysis of the neibourhood as a whole. From the grouping of the found characteristics, sub-zones had been delimited, where the real object of study was detached to be analyzed. From the Sub-zoning, a statistic sampling was carried through with the intention to examine which of the urbanistic index is found in the dwellings of that already materialized place. This sampling, of one hundred and eighteen residences, was carried through by measurement of the lots and existing constructions in these places. Through this survey, for each habitacional unit, area of the lot, constructed area, retreats and coefficient of exploitation had been calculated. The comparison between the legislation parameters and the index found in the place reveal an expressive index of urbanistic irregularity and the necessity of special regulation for the Rocas neibourhood due to its specific social-space characteristic

Mapeamento de recifes no Rio Grande do Norte: Touros e Macau/RN

Studies on the Brazilian continental shelf were developed between Touros and Macau-RN (NE Brazil) with the aim to mapping carbonate buildups, and especially, reef ecosystems. Remote sensing, submarine movies, bathymetric survey and diving were the methods used. This paper will focus on three main aspects of the Rio Grande do Norte reefs: 1) characterization of the coral fauna; 2) the classification and, 3) the distribution of the main northriograndense carbonate buildups. Reefs environments are found predominantly on the inner shelf adjacent to Touros, at depths shallower than 10 m. These reefs generally show NW-SE orientation parallel to the coastline and constitute groupings of knolls and patch reefs. A prominent carbonate buildup, where the corals are almost absents and algae incrustation is thin, occurs in average depths of 25 m, along the northern part of Rio Grande do Norte State and is classified as sandstone bank. Others sandstone banks, with smaller lengths and heights were mapped around 10 m depth. They should be related to an ancient coastline; however the corresponding litostratigraphic unit was not defined. This work is a contribution to the mapping of coral reef, in particular, and carbonate buildups, in general, on the Rio Grande do Norte coast

Caracterização geológica tridimensional e monitoramento de dunas no litoral oriental do Rio Grande do Norte

This work presents geophysical and geological results obtained in a dunefield located in the east coast of Rio Grande do Norte State, with the aim to recognize the aeolian body depositional geometries to a future geologic modeling of the aeolian petroliferous reservoirs. The research, which was done in blowouts region situated at Nisia Floresta Municipally, included the characterization of external geometries with GPS and internal geometry analysis by GPR. Data was integrated in GoCAD software, where it was possible the three-dimensional characterization and interpretation of the studied deposits. The interpretation of GPR profiling allowed identifying: First-order bounding surfaces that separated the aeolian deposits of the Barreiras Formation rocks; Second-order bounding surfaces, which limit dune generations and Third-order bounding surfaces, a reactivation surface. This classification was based and adapted by the Brookfield (1977) and Kocurek (1996) propose. Four radarfacies was recognized: Radarfacies 1, progradational reflectors correlated to foresets of the dunes, Radarfacies 2, plain parallels reflectors related to sand sheets, Radarfacies 3, plain parallels reflectors associated to reworking of the blowout dune crest and Radarfacies 4, mounded reflectors associated to vegetated mound of sand or objects buried in subsurface. The GPR and GPS methods was also employed to the monitoring of dunefields susceptible to human activities in Buzios Beach, where the constructions along the blowout region and the tourism are changing the natural evolution of the deposits. This fact possibly to cause negative impacts to the coastal zone. Data obtained in Dunas Park, a unit environmental conservation, was compared with information of the Buzios Beach. There is a major tendency of erosion in Buzios, specifically in blowout corridor and blowout dune

História de uma completiva: origem e desenvolvimento do complemento oracional introduzido por se do português

O propósito deste trabalho é investigar o percurso histórico da oração completiva iniciada pela conjunção se do português, que também introduz, nessa e em outras línguas românicas, uma oração adverbial condicional. Com base em registros de filólogos e romanistas, demonstra-se que a similaridade existente entre essas orações é resultado de gramaticalização da oração condicional que, no latim, passou a funcionar como oração completiva, em razão da extinção das partículas interrogativas que passaram a ser substituídas pela conjunção condicional latina si. Como oração completiva, a oração com se submete-se à gramaticalização, integrando-se à oração matriz de um modo que, conforme proposta de Hopper e Traugott (1993) e de Lehmann (1988), é próprio a construções completivas. A forma que tem essa oração de se gramaticalizar, incorporando-se à oração matriz, é, entretanto, diferente do que é previsto ocorrer a uma completiva introduzida por que, uma diferença que se deve, sobretudo, ao significado hipotético que a completiva com se preserva de sua fonte histórica. Demonstra-se, por fim, que, do português arcaico ao português contemporâneo, a gramaticalização do complemento oracional introduzido por se não se configura em mudança diacrônica, já que essa gramaticalização é atestada desde períodos mais remotos, em textos do século XIV.

Principais normas e recomendações existentes para o controle de vibrações provocadas pelo uso de explosivos em áreas urbanas: parte II

As atividades que envolvem o uso de explosivos devem ser controladas, não só com relação ao desmonte de estruturas (rocha e outros materiais), mas também quanto a danos estruturais em edificações próximas (casas, edificações históricas, etc.) e outros impactos ambientais como vibração, propagação de ruídos, ultralançamentos e sobrepressão atmosférica. Tais atividades são regidas por normas técnicas que sugerem parâmetros de medição e limites definidos na avaliação de prováveis danos. No caso específico de minerações em áreas urbanas, a velocidade de vibração de partícula (Vp), normalmente expressa em mm/s, é o parâmetro que tem dado melhor correlação na avaliação de possíveis danos às estruturas civis, atribuídos às vibrações do terreno. As diferentes normas existentes apresentam valores de Vp que variam de 2mm/s para edifícios históricos até 150mm/s para construções em concreto armado. A maioria delas considera na avaliação de danos estruturais, além da velocidade, a freqüência da vibração. Algumas normas foram elaboradas com base em dados experimentais, analisando parâmetros como o tipo de construção e o material nela utilizados, outras se basearam apenas em valores empíricos, mas todas apresentam valores conservativos. A norma brasileira não avalia o parâmetro freqüência e não classifica os diferentes tipos de estruturas civis, restringindo-se ao valor resultante da velocidade de vibração como parâmetro medido, sendo, assim, limitada e deficiente em relação às normas internacionais. A coletânea aqui apresentada reuniu as normas nas Américas e em outros continentes, além de uma comparação com as normas européias mais importantes em âmbito mundial.

Produção e estética dos conteúdos televisivos em ambiente de convergência: o caso da TV Unesp

Novos processos de produção de conteúdo estão reconfigurando os organogramas e os fluxogramas de setores ligados à criação de programas informativos e de entretenimento nas emissoras de televisão. A elaboração de conteúdos centrados em um modo de Comunicação que procura contemplar a participação e a colaboração da audiência nas construções discursivas impõe a existência de estruturas capazes de responder às demandas de uma plataforma multimídia, engendrada por tecnologias que possibilitem a conectividade entre os diversos dispositivos móveis e portáteis. Além de evidenciar os desafios de caráter organizacional, o presente trabalho, baseado em pesquisa bibliográfica e documental, tem como objetivo discutir as implicações estéticas dos conteúdos gerados para o consumo multimídia. Assim, toma como objeto de análise a estrutura e a programação da Televisão Universitária Unesp, da Universidade Estadual Paulista, em fase de implantação no campus de Bauru-SP.

Reflexão e identidade profissional do professor de LE: que histórias contam os futuros professores?

Este artigo relata os resultados de um estudo realizado com alunas de graduação em Letras, Português - Língua Estrangeira (Inglês, Espanhol, Italiano, Japonês, Francês e Alemão). Objetivou verificar as metáforas, regras da prática e princípios que as alunas identificaram durante um processo de reflexão sobre suas formações profissionais. Foi possível identificar o impacto desses elementos em seus processos individuais de desenvolvimento de identidades como professoras. O resultado foi um conjunto de histórias biográficas escritas (fontes de experiências) nas quais as participantes se baseavam para constituir suas identidades profissionais como professoras de línguas estrangeiras. Nesses processos, elas puderam construir ligações significativas entre os aspectos teóricos evidenciados nas leituras que realizaram durante o período da pesquisa e os vários eventos marcantes de suas narrativas orais acerca da carreira profissional. A associação dos vários aspectos de suas histórias pessoais às questões teóricas que foram discutidas durante a pesquisa revela processos de construções de identidades profissionais como professoras de línguas estrangeiras.
