This report has as its objective the setting up of a social cartography, mapping and characterizing non-governmental organizations working with adolescents and young people (OSC) in the western districts of the city of Natal. Characteristics such as the profile, themes and principal activities, how the organizations fit into the public sector and their participation in social networks are observed. Thus common differences and similarities which serve as a means of indentification, take as reference the symbolic cartography of Boaventura of Sousa Santos. Since there are relatively few studies relating to civil society of Rio Grande do Norte and in particular, Natal, the starting point was the setting up of a database allowing for a general overview. Hence a panorama of the organizations could be observed: where they are located, when they were formed how they operate and their relationships with other sectors (the state, the market and civil society) in addition to basic facts and location. The principal lines of enquiry were a) the OSC which operate with the public comprising adolescents and young people and b) the OSC operating or having branches in four suburbs on the periphery of the western administrative region of the city (Felipe Camarão, Bom Pastor, Cidade Nova and Guararapes).The present report has identified the impacts of ongoing social transformation caused by the process of globalization ,by the various currently contested political projects which are as follows: the project of neoliberal globalized capitalism(hegemonic)and the project of social emancipation (contra-hegemonic),how these are seen from the local viewpoint and how they influence the profiles and operation of the cartographic organizations. The area of the OSC is a heterogenous one with political, cultural and ideological strains, characterized by its infiltration, its local/global and multicultural dimensions. As civil organizations are fundamental in the processes of transformation within society, and following the idea of social emancipation referred to by Boaventura Santos, the enquiry classified the organizations according to the afore-mentioned characteristics, establishing eight types of associations. These different types and their respective characteristics were analysed from a related perspective using the mechanisms of symbolic cartography: scale, projection and symbolisation. The theoretical references underpinning this research arise from the debate on civil society which becomes redefined as a result of the dispute involving the two afore-mentioned political projects. These demand the theoretical application of the comprehension of heterogeneity in its diversity and complexity together with the idea of social emancipation.The main authors consulted were Boaventura de Sousa Santos, Antonio Gramsci, through the texts translated by Marco Aurelio Nogueira; Carlos Nelson Coutinho and Alberto Rivera ,who supported the construction of the types of associations identified by the local reality.Finally this research enabled an understanding of the current form of social action happening in the Space of the Four Neighbourhoods (Espaço dos 4 Bairros) and how the distinct profiles analysed together with the ares of operation of the organizations define their emancipatory potencials within the following two poles: regulation/adaptation and emancipation/transformation

This doctoral thesis addresses the environmental issues and its vinculum with the tourism through the protected natural areas, in particular the conservation units, which consists in territorial areas created and demarcated by the government in order to protect ecosystems that have a high ecological and scenic-landscaped representativeness designed to the contemplation and controlled public visitation. In regard to its use for the touristic activities, are conceived while socio-environmental and symbolic materiality built around an imagery view of a nature-show, designed to attract visitors, aiming ensure the maintenance and reproduction of the capital in an entrepreneurial and preservationist way in the Metropolitan Region of Natal. It s a study about the Dunes State Park Jornalista José Maria Alves and the Jenipabu Environmental Protected Area, both created with the purpose of favor the implantation and empowerment of the touristic area through the State intervention as the main articulator agent of a new process of urbanization that uses the city marketing and the ideological discuss of environmental sustainability to recreate the imaginary of lost paradise and incorporate into the daily universe of tourists visiting the state of Rio Grande do Norte. The unveiling of this empirical reality made possible the construction and defense of the terms environmental entrepreneurship and compensatory preservationism, to explain how the formatting and idealization of this paradisiacal scenarios produce the commoditization of nature in an efficient and competitive way

In the current systemic crisis, economic policy is directed to correct the consequences of the functioning of this metabolism, but within the limits of the capital. From this perspective, decision makers propose trade policies, agricultural and industrial to ensure conditions for economic growth. However, as a dead end, there is failure of the State in giving efficacy to the operation of all segments of the economy, especially given the budget constraint. Public managers are forced to seek external resources, resuming the cycle of political allegiance to the interests of international financial and banking representatives, installed in so-called multilateral. The complex ideological capital comes into play in trying to convince society that the paths taken by governments are inevitable, and that capitalism can be "humanized", even with the realization of the growing inequalities caused by historical irrationalism of the production process of capital . In this sense, emerging concepts that attempt to demonstrate the compatibility of the system to real human needs. This ideological offensive is intended to legitimize the capital. The so-called third sector has a special highlight with the concept of corporate social responsibility. It creates a political environment in which the inevitable mix-up with new illusions offered by and often funding the metabolism of capital in order to perpetuate this system. In this context, political elites, and considerable portions of the academy, embark on "waves of capitalist optimism," while the sociometabolismo capital expands its historical limits, driving forces postponing their collapse, but that cause human suffering and ecological stress. Wars are disseminated to strengthen the deadly war industry and the automobile industry; and devastating the environment of which depends the capital system. In this scenario disassemble, propositions emerge around a "new social pact" in order to minimize the adverse effects of the dynamics of reproduction of capital. The business class is called to exercise its role through the discourse that appeals to social responsibility programs, in order to intervene directly in the "social question". The core of this research is precisely this point. Although there is considerable scholarship on the phenomenon of Social Responsibility and Corporate Citizenship, there is also an evident lack of this approach focused on the banking sector in Brazil. The importance of rentier capital increased ownership of shares in the wealth produced by all of Brazilian society, justifies a sociological research project on Social Responsibility in the domestic financial sector. In this sense, it was decided to perform a dynamic approach to the "Corporate Citizenship" in the banking industry, specifically in the Bank of Brazil. As this is a key institution, is important analyze of the impacts of this strategy fetish of capitalist reproduction, in order to evaluate the social legitimization of rentier capital in Brazil. In this scenario of the abundance of the discourse on social responsibility there exist a progressive impoverishment of professional work in this segment in Brazil. There is a dramatic mismatch between rhetoric and practice because of the trend of deepening vulnerability of the working conditions of the Brazilian bank worker, from the 1990's. In the specific case of the Bank of Brazil, the first initiative of the institution was to conform to the principles of the UNO and the Ethos Institute, aiming to align their domestic policies to this new strategy of domination of capital. The purpose is to place the Bank in the ideological sphere of corporate social responsibility, just as with its partners in the private financial intercapitalist competition. Indeed, in the internal ambit of the Bank of Brazil, there is a policy to adjust its functional segments to the doctrine of Social Corporate Responsibility. The concepts of this doctrine is presented as something inexorable. There are no alternatives. The Bank of Brazil operates in a highly competitive market, the segment featuring the dominance of financial capital accumulation today. For this reason it can not fail to incorporate the technological advances organizational. For employees there is no alternative but to adapt to this new set of ideas proposed by the metabolism of capital

O objetivo deste trabalho foi analisar a variabilidade genética da raça Brahman no Brasil, por meio da análise de 15.851 pedigrees. O arquivo de dados foi dividido em dois períodos: 1998-2001 e 2002-2005. A variabilidade genética foi avaliada por parâmetros baseados na probabilidade de origem do gene: número efetivo de ancestrais, número efetivo de fundadores, número efetivo de genomas remanescentes e coeficientes de parentesco e de endogamia. Os valores encontrados quanto ao número de fundadores mostraram que a população está em expansão, embora o número efetivo de fundadores tenha diminuído de um período para outro. Os resultados foram diferentes em relação ao número de ancestrais e genomas remanescentes, que apresentaram crescimento de 23% nos períodos avaliados. O coeficiente de endogamia diminuiu nos períodos estudados, porém o coeficiente de parentesco inter se cresceu. Poucos ancestrais apresentaram grande contribuição genética para a população, o que evidencia a utilização de poucos indivíduos na reprodução. A raça Brahman, no Brasil, encontra-se em expansão, caracterizada pela diminuição do coeficiente de endogamia e aumento nos números efetivos de fundadores e de genótipos remanescentes. Entretanto, a variabilidade genética da raça mostra aumento do parentesco inter se e grande concentração do patrimônio genético de poucos indivíduos na população.

The tradition and living in African-Brazilian religious spaces, called yards, reveal how dynamic the reproduction and exchange of knowledge are, and that through their worldview, reveal ways of dealing with health and disease. The yards are culturally rich territories, in which people shape concepts, practices, and beliefs about health, disease and forms of healing, passed on from generation to generation through oral tradition. With the advent of HIV/AIDS from the 80s, a new challenge is established in the community of the yards and in the individual trajectories of people affected by the disease, who since an early age participate in this religious practice. The objective of this research is the analysis on the stigma in living with HIV/AIDS in yards of Umbanda in Fortaleza-Ceará, considering the (re)production of social dramas experienced by the community in question. During the investigation we adopted two basic parameters: the first one considers the understanding of the reproduction of stigma (or deteriorated identity) in relation to HIV/AIDS in its socio-historical dimension and its effects in the investigated context (Goffman, 1988). And the second one refers to the creation and reproduction of social dramas as a social experience carried through learning, handling and symbolic performance, which is reproduced in four stages: rupture, crisis, corrective action and reintegration (Turner, 1971)

The present work analyses and discusses the sociability in the culture of contemporary cities focusing on the theme of fear and violence in the daily life of squares in the city of João Pessoa-PB. We analyse the relations between places in town and make correlations of history and setting of neighborhoods with the process of urban growth, including recent interventions of public authorities in their public spaces. We observed in this dynamics social attitudes and actions that range from a desired peaceful coexistence to social exclusion. Thus, we discuss, based upon the imaginary vision, that the squares exist as a locus of equality, citizenship and political, and, also, as a space for everyone, despite the existence of symbolic forces working towards segregation and privatization, ruled in fear and violence. We aimed to investigate the different symbolic logics from the issue of fear and violence that allows the exclusion and the inclusion of groups and individuals in the quotidian use of public spaces of contemporary cities. We believe that the social action is demarcated by violence ant its corollary, the social fear, and operates based on the logic of a relational game always confrontational but experienced in different forms according to the social segment or group under study. We used a qualitative and quantitative methodology relating data and statistical analysis with categories created for the understanding of subjective factors. Our analyses combined ethnographic elements, periodics research and images of the city and its spaces, with the contribution of a survey that allowed comparisions of five squares of neighborhood based on the daily life under investigation. Our proposal was to deepen the investigations related to the public space of contemporary cities, expanding the look on João Pessoa and its cultural dynamics with an analysis of discourses, images, the collective imaginary and the social appropriation of the spaces based on fear and violence. The research accomplished in different areas and the analysis of images and speeches published in newspapers reports, books, advertising etc. allowed the approach of differentiated patterns of sociability in the same urban process. The neighborhoods in study are indeed spatially and economically distanced and the process of creation and construction of squares occurred in very different ways in the respective location. We defend the thesis that neighborhood community squares provide reinvigorated spaces and public spheres in the urban process and in the dynamics of sociability in the cities. These squares are also social spaces par excellence for the perception of the logic of individualism and segregation so marked by fear and violence in contemporary cities

Os cavalos-marinhos têm cativado a imaginação e a curiosidade dos seres humanos por centenas de anos. No entanto, nos dias de hoje, esses animais correm um sério risco de extinção por fatores como a pesca desordenada para suprir os mercados de peixes ornamentais e da medicina tradicional chinesa e principalmente, a destruição do seu habitat. Nesse contexto, é crescente o número de estudos sobre a ecologia, a biologia (reprodutiva, especialmente) e o cultivo de várias espécies do gênero Hippocampus, inclusive para fins conservacionistas e de recomposição de estoques. Duas espécies de cavalos-marinhos são encontradas no Brasil: Hippocampus reidi Ginsburg 1933 e Hippocampus erectus Perry. No entanto, as informações sobre essas espécies estão basicamente restritas ao seu grau de ocorrência ou a sua área de ocupação. No presente estudo, foi avaliado o desempenho reprodutivo de Hippocampus reidi do estuário do rio Potengi (05° 47' 42'' S; 35° 12' 34'' W), em Natal, Rio Grande do Norte. Para tanto, cavalos-marinhos grávidos (n = 38) foram coletados no referido estuário nos meses de setembro, outubro e novembro de 2008 e julho, agosto, setembro e outubro de 2009 e mantidos em laboratório até que liberassem os filhotes. O comprimento padrão (CPA), altura (ATA), volume da bolsa (VB) e peso úmido (PuA) dos adultos, bem como o comprimento padrão (CPF), altura (ATF), peso úmido (PuF) e peso seco (PsF) dos filhotes foram determinados. Os resultados obtidos mostraram que houve correlações significativas entre o CPA e a ATA (r²=0,171), CPA e PuA (r²=0,624), CPA e VB (r²=0,256), ATA e PuA (r²=0,788), PuA e VB (r²=0,211), CPF e ATF (r²=0,903) e CPF e PsF (r²=0,163). A análise de correspondência (AC) que associou as classes do comprimento padrão dos adultos (CPA) e o volume da bolsa de H. reidi ao número de filhotes mostrou que animais entre 19 cm e 21 cm e com volume de bolsa entre 3 mL e 4 mL foram os que liberaram o maior número de filhotes. Os resultados do presente estudo também indicam que o tamanho mínimo de captura recomendado pela CITES (10 cm de altura) para H. reidi deve ser revisto, uma vez que não foram encontrados animais menores que 13,5 cm que estivessem grávidos. Finalmente, o número médio de filhotes por desova obtido no presente estudo (n = 775 ± 398 filhotes) realçou o potencial reprodutivo de H. reidi e a necessidade de estudos adicionais com esta espécie

Cyanobacterial blooms are common in eutrophic reservoirs in Brazilian northeastern semi-arid. Given this reality, the present study aimed to analyze the effect of potentially toxic cyanobacterial blooms in Gargalheiras reservoir (semi-arid) on the cladocerans Ceriodaphnia dubia and Daphnia gessneri. In vitro chronic bioassays were performed with reservoir water dilutions from August/2011 to May/2012 and the following effects were evaluated on: intrinsic rate of population growth (r), reproductive parameters (age of first reproduction and fecundity per capita) and cladocerans movements. Phytoplankton was dominated by Cylindrospermopsis raciborskii and Planktothrix agardhii and saxitoxin and microcystin were detected in reservoir water. In most months C. dubia showed differences in r between control (absence of cyanobacteria) and treatments, and has shown negative effects on reproductive parameters. In all months paralysis of swimming movements was observed in C. dubia when both C. raciborskii and saxitoxin (cyanotoxin neurotoxic) were present in water. While C. dubia was sensitive to the reservoir water containing cyanobacteria, D. gessneri showed less intense negative effects in r and reproductive parameters. Furthermore, D. gessneri showed no paralysis of swimming movements. These results support the hypothesis in the literature that D. gessneri is resistant to the Cylindrospermopsis effects. The clone‟s life history may be a key to understand the results. The C. dubia clone, isolated from eutrophicated environment, is in the lab for ten years and it is an exotic species in Brazil. D. gessneri is a common species in the country and this clone was isolated from the Gargalheiras reservoir (where there are constant blooms of potentially toxic cyanobacteria) a year ago. Perhaps the recent contact with cyanobacteria explain the higher resistance presented by this D. gessneri clone. In conclusion, the cladocerans studied have different levels of sensitivity to cyanobacteria, characterizing species-specific responses

For a long time, we believed in the pattern that tropical and south hemisphere species have high survival. Nowadays results began to contradict this pattern, indicating the need for further studies. Despite the advanced state of the study of bird population parameters, little is known about their variation throughout the year and the factors affecting them. Reproduction, for example, is one factor that may alter adult survival rates, because during this process the breeding pair allocates resources to maintain itself to maintain offspring, making itself more susceptible to diseases and predation. The aim of this study was to estimate survival and population size of a Central and South America passerine, Tachyphonus rufus (Boddaert, 1783), testing hypotheses about the factors that define these parameters. We performed data collection between Nov/2010 and ago/2012 in 12 ha plot, in a fragment of Atlantic Forest in northeastern Brazil. We used capture-mark-recapture methods to generate estimates using Closed Design Robust model in the program MARK. We generated Multi-state models to test some assumptions inherent to Closed Robust Design. The influence of co-variables (time, rain and reproductive cycle) and the effect of transient individuals were measured. Capture, recapture and apparent survival parameters were defined by reproductive cycle, while temporary dispersal was influence by rain. The estimates showed a higher apparent survival during the non-breeding period (92% ± 1%) than during breeding (40% ± 9%), revealing a cost of reproduction and suggesting a trade-off between surviving and reproducing. The low annual survival observed (34%) did not corroborate the pattern of high rates expected for a tropical bird. The largest population size was estimated to be 56 individuals in Nov/11, explained by high recruitment of juveniles, while the lowest observed in May/12: 10 individuals, probably as a result of massive influx of competitor species. Results from this study add to the growing literature on life history of Neotropical species. We encourage studies like this especially in Brazil, where there are few information, and suggest that covariates related to habitat quality and environmental changes should be tested, so that we can generate increasingly reliable models

Many prey organisms change their phenotype to reduce the predation risk. However, such changes are associated with trade-offs, and can have negative effects on prey growth or reproduction. Understand how preys assess the predation risk is essential to evaluate the adaptive value of predator-induced phenotypic and its ecological consequences. In this study, we performed a mesocosm experiment to test: i) if growth and stoichiometry of Lithobates catesbeianus tadpoles is altered in response to giant water bug presence (Belostoma spp.); ii) if these responses depend on tadpoles density in environment. Here, we show that tadpoles growth and stoichiometry are not changed by predator presence, neither in low nor in high densities. Our results suggest that tadpoles exposed to predation risk regulate their physiology to preserve the elemental stoichiometric homeostase of their body and excretion. Further, point out to need for future studies that elucidate under what conditions growth and stoichiometry are changed in response to predation risk

This study analyzes the institucional environment and its changes around the carcinicultora activity in Rio Grande do Norte from the understanding of its trajectory and the macroinstitucional elements micron and that characterizes the activity in the period of 1999 the 2009. In the analysis of the occured institucional changes in the carcinicultura the Guaraíra Estuary is overcome as space reference, located in the eastern coast of the Rio Grande of the North. The analysis proposal has for base the adoption of the conceptual support of the innovative institucionalistas and neoshumpterianas theories, for understanding that these bring complementary and enriching elements that will allow an analysis, not static, but, dynamics of the carcinicultora activity. It was verified that the crisis brought up for the antidumping action, for the problems of the illnesses that had abated the shrimp, for the depreciation of the Real, among others it led to an overturn in the productive conjuncture of market and forced the alteration of the effective institutions. This institucional alteration, goes in the direction to search to take care of the new demands of the carcinicultura that was possible for the solidity of the institucional foundations constructed throughout the thirty previous years and the consequent consolidation of the composed institucional apparatus for rich a mix of organizations, not only for agencies of government, as well as for organizations with social representation

This study aims to the evaluate the determinants for rural households northeastern be pluriactive, in 2011. For this, at first, we conducted a review of national and international literature in order to get beyond the theoretical part which refers to the study of pluriactivity identify possible determinants of the phenomenon. In this rescue, it was the observed determinants could be macroeconomic in nature and / or microeconomics. Therefore, it became necessary to describe the characteristics of the region under study, the Northeast. In order to identify the determinants were two estimated Probit models, one based on the literature review and the second with a variable characteristic of the Northeast, the transfers. For this, we used the PNAD in 2011. The results indicate both the microeconomic determinants are : gender, race, age, years of education, hours worked, number of family members, per capita income, transfer the macroeconomic in nature: living conditions (water, energy, sanitation ), housing location. In addition to identifying the determinants, the Econometric model allows to know the probability of each variable on the dependent variable, which stood out: the transfer variable, gender, per capita income, number of family members, housing conditions and housing location. Therefore, it is concluded that it is the set of determinants (macro and micro) allow rural families become northeastern pluriactive. However, one can not fail to consider may also have other determinants were not captured due to the availability of data, which may be indications for future studies. In summary, the pluriactivity in the Brazilian Northeast is a phenomenon distinct from found in Europe and southern Brazil. It is a pluriactivity survival that is part of the strategies of rural households in the Northeast to ensure their social reproduction amid the poverty of the region

The subject of study of this work is the teacher spawning of the Instituto de Educação do Pará in the decades of 1970 and 1980. It aims the enablement offered by the institute concerning the racial issue. The thesis highlights the inferior condition to which the black student is relegated and the discrimination it suffers. Our argument is to affirm the omission of the curriculum and the reference resources as far as the racial issue is concerned. Before the singularity of the Brazilian case a country with a slavish background, with serious social unbalance problems, many of them resulting from the racial segregation implemented by that slavish system , this work claims that the preparation of the teachers for dealing with this issue is crucial, since the absence of this preparation leads to the reproduction of the prejudice inside the classroom. This thesis is based on the theory of Pierre Bourdieu on the notion of habitus and symbolic power

Este trabalho foi realizado para avaliar o desenvolvimento e reprodução de Tetranychus urticae em cultivares comerciais de mamão Carica papaya. Foram utilizadas cultivares do grupo Formosa (Tainung 01 e Calimosa) e do grupo Solo (Golden e Sunrise). Para iniciar o bioensaio, foi transferida uma fêmea fertilizada por disco de folha (n=50 repetições) e retirado após um período de 12h, sendo avaliada a cada 12h, registrando-se o período de incubação, duração do estágio de imaturo, longevidade e fecundidade dos adultos e viabilidade desses estágios. Os resultados indicaram que as cultivares de mamão Tainung 01, Calimosa, Sunrise e Golden são bons hospedeiros para T. urticae. O parâmetro viabilidade não sofreu influência das cultivares em todas as fases de desenvolvimento avaliadas, apresentando valores superiores a 90%. Não houve diferença estatística entre as cultivares nos parâmetros: período de pre-oviposição e viabilidade dos ovos. A cultivar Tainung 01 apresentou menor potencial hospedeiro, embora houvesse menor duração nos estágios de ovo, larva, protoninfa e ovo-adulto. Nos parâmetros de tabela de vida e fertilidade, apresentou menores valores de Ro, r m e λ e maior valor de Td. Entre as cultivares, o Sunrise apresentou um elevado potencial hospedeiro para T. urticae, pois essa cultivar proporcionou a maior produção de ovos por fêmea, maior longevidade das fêmeas, bem como a maior taxa de reprodução (maior Ro, r m e λ e menor valor de Td).
