Dimensionamento e sobreposição de nichos dos portunídeos (Decapoda, Brachyura), na Enseada da Fortaleza, Ubatuba, São Paulo, Brasil

The niche breadth of the Portunidae and their overlap on the subtidal sediments of Fortaleza bay, Ubatuba (São Paulo) was analyzed. Samples were made monthly from November/1988 to October/1989, inseven areas of the bay using a shrimp fishery boat equipped with two otter-trawls. Each area was characterized based on environmental factors such as depth, temperature, salinity, dissolved oxygen, organic matter and granulometric composition of the sediment. The number of individuais of each species was registered to each area (resource). Levins's standardized measure (BA) and niche percentage were calculated. Five species of swimming crabs were recorded in this study: Callinectes ornatus Ordway, 1863, Arenaeus cribrarius (Lamarck, 1818), Portunus spinimanus Latreille, 1819, Callinectes danae Smith, 1869 and Portunus spinicarpus (Stimpson, 1871). The widest ecological niche occurred to C. ornatus, present in all sampled areas (generalist species). Such fact can be related to high sediment tolerance when it is compared to P. spinimanus (especialist species) which was limited to the areas with coarse granulometric fractions. Highest niche overlap was verified between C. danae and A. cribrarius may be due to greater salinity tolerance of these species. The low occurrence of P. spinicarpus and its reduced niche size in Fortaleza Bay are due to association of this species to cold water currents (ACAS) more evidente in smaler depths during summer months. One future evaluation of the portunid diet can be useful to complement informations about this important aspect of the marine ecology.

A construção das representações sociais na relação da polícia militar e a sociedade Aracajuana

In recent years, issues involving public safety have gained more prominence in scientific debates, the media, and common sense, because undoubtedly the feeling of fear and insecurity caused by the increase in violence overall, has spread like construction element of social representations, both in individual levels, as well as collectively. Violence is a social phenomenon existing in human manifestations, from the older societies, ie it was present in all historical periods, but in different ways in the subjective and objective, having had the task of being the central element in modeling process for the formation of individual behavior, both in older societies as in modern society. However, it has a peculiar feature of acquiring new contours to the extent that the individual and collective behaviors are modified in relation individual-violence. In this sense, the institutions that establish the order from the control of violence, have their social representations in the context of social relationships permeated by elements of violence, fear and insecurity, that shift the subjective feeling of insecurity, or existential, for a concrete plan and goal, namely to the level of physical insecurity in daily life in the modern world. The objective of this study was to capture the construction of social representations of the population in Aracaju on the police institution and the figure of the policeman in the contemporary context. We focus our attention only to the institutions of order, which constitute the field of the apparatus of public security and social protection of our state

A reestruturação sócio-religiosa em Sergipe, no final do século XVIII

The issues surrounding the religious have been given greater importance in scientific discussions and the media. Discussions on religion and religiosity have become widespread as a means for construction of social representations, both as individual levels, in addition, in the collectivity. This work deals with the construction of the order of Jesus, missionaries and settlers of the projects that marked the presence of the Jesuit missionaries, from colonization to the religious restructuring imposed after the expulsion of the Jesuit Order in Sergipe. Expulsion is what happened in the midst of political and administrative changes made by the Portuguese government in the mid-eighteenth century, which had representation at the Marquis of Pombal its creator. Understanding the religious and social restructuring, designed here in the practices and representations of popular and official. This restructuring has had on the religious brotherhoods, religious orders and other representations, an important symbolic presence in the spaces sociorreligiosos linked to Catholic practices in Sergipe. Representation such that officially came into the vicars pasted their legal representatives, in the maintenance of religious practices in the boroughs and cities Sergipe

Jovens assentados, jovens estudantes, jovens professores: juventude em assentamentos rurais do RN

This work discusses how schooling processes can contribute to young settlers resignify their relationship with rural settlements where they live. We want to understand youngster s place, his relationship with local community, social movements and their acting, after formation, at their localities. Thereunto, we tracked a group of students of Land Teaching Course, developed through a partnership between UFRN, INCRA and MST in the years 2004 to 2007. We observed their trajectories, the learnings provided by the Course and how Formation Centre experiences contributed to their agent conditions, offering them choice opportunities on different fields. We understand that formation process enabled them to have individual gains, widening their range of choices, while have contributed to development of areas in which they live, from their collective action. Social practices experienced in collective environment, combined with education access, provided a set of knowledge. These learnings have enabled youngsters to assume positions in participation areas which have been opened at school, while teachers, at social movements and at associations that manage the settlements

Testemunhos de um tempo vivido : fragmentos e contextos de uma narrativa de Janduís-RN

Shows up the memory of the elderly, as a consistent experience in the in the construction of the social memory of Janduís, Rio Grande do Norte, where the research takes place. Through an autobiographic narrative, in a qualitative approaching, the intent is to stand up aspects about the individual history and collective memories, starting in a simple question: what did they remember? A question that turns into many others, as how the remember and under which circumstances. So, the lived and remembered moments are the subject of this paper, as these testimonials shows and reveals the citizens typical aspects, intending to telling (again) the city s history by the memories of this people. By oral statements and the analysis that followed, subjective aspects that made a social memory, highlight in violent episodes, that, now remembered, occurred in the historical sediment, which connects several social times, establishing a narrative standard. In Janduís, this standard is about the memory that sticks out their individual ways, and the collective life, in the past, standing out the fair and the events that occurred on it, as the most remembered place, where the memories go stronger. When they narrate are incorporated others facts, the story is reinvented, connecting the past to the future. The paper also revels builders subjects aspects of a social memory, as historical sediment that joins the social times. At the present moment, the fair, to them, is a place that doesn t exist anymore; for the city, is a place of enlargement of women s presence at the trending spaces, which means a place of social transformation. That being said, the fair, in both times, present and past, turns into a analysis object, with important elements to reference narrative s time and place. And how the narrative update the past recorded in the old citizen s memory. What was intended to do was articulate the memory and the history form temporal and special etching that define the place and the narrative context: the lived and the remembered at the group s day by day. In that way, were identify the collective memory s common elements, enunciating the memory and the narratives that update that history, influencing and being influenced, forming in memories in a collective phenomenon fueling the local imaginary

Digestibilidade e balanço de nitrogênio em ovinos alimentados à base de dietas com elevado teor de concentrado e níveis crescentes de polpa cítrica peletizada

O experimento foi realizado com o objetivo de determinar os coeficientes de digestibilidade, a ingestão de nutrientes e o balanço de nitrogênio de dietas com 20% de silagem de milho e 80% de concentrado e 0, 25, 40 e 55% de polpa cítrica na matéria seca total, substituindo o milho em grão. em delineamento de blocos ao acaso, foram utilizados oito cordeiros mestiços, com nove meses de idade e 34 kg de peso, mantidos em gaiolas individuais com dispositivo para separação de fezes e urina. O período de coleta de alimento, sobras, fezes e urina foi de seis dias e a quantidade de alimento oferecido correspondeu à média do consumido nos três últimos dias do período de adaptação. O experimento foi desenvolvido em duas fases, utilizando-se os mesmos animais, que foram distribuídos em blocos pelo peso. Os resultados foram analisados por regressão polinomial. Houve aumento linear nos coeficientes de digestibilidade aparente da proteína bruta e da fibra em detergente ácido, com o aumento da participação da polpa cítrica na dieta. Os demais coeficientes de digestibilidade não diferiram entre si e foram, respectivamente: 71,8; 73,3; 77,2; 63,5; e 72,2%; para matéria seca, matéria orgânica, extrato etéreo, fibra em detergente neutro e hemicelulose. O teor médio de nutrientes digestíveis totais foi de 72,39%. Houve aumento linear da ingestão de matéria seca e de nutrientes digestíveis totais por dia e por peso metabólico, com o aumento de polpa cítrica na dieta. O mesmo ocorreu com a quantidade de nitrogênio ingerido, absorvido, urinário e retido. O aumento da participação da polpa cítrica peletizada até 55% da matéria seca da dieta, substituindo o grão de milho, implicou em melhor aproveitamento da fibra e eficiência no metabolismo do nitrogênio.

Ethopoiésis e Heavy Metal: Subjetivação e consumo na cena de Natal-RN

Our research intends to comprehend the configuration of the resistance (Foucault) as the stylization of life in the contemporary world, taking Heavy Metal as the specific object of study. We believe that Heavy Metal is an ethopoietical device which admits practices of freedom withstanding the reified moral habits since the beginning of the socialization. This is reflected, mainly, in the creation of new individual and communal ways to stylize the life. We also suggest an expansion of Foucault s concept of resistance, considering the idea of consumer society described by Zygmunt Bauman. Our hypothesis understands that the contact with the underground of Heavy Metal provides new ethical manners (Foucault), where the individual take the Heavy Metal as a way of life. At this point, the consumption becomes a key-word since the participation in the underground of Heavy Metal is a way of consumption out of the rules of marketing a practice of freedom, a way of particular existence , being different in both mode and duration

Juventude rural e projetos de vida: a experiência do consórcio social da juventude rural em São João do Sabugi

The presented research however has as object to apprehend the contribution of the Social Trust of Agricultural Youth in Is João of the Sabugi, in the individual and collective projects of life of the agricultural young. In it interests to know them which are the dreams and desires of these young, its relation with familiar agriculture, its desires of permanence in the field, as well as the relation of the trust with the fortalecimento of its projects of life. Thus, the general objective is to argue the contribution and influence of the Social Trust of Agricultural Youth in Is João of the Sabugi, in the individual and collective projects of life of the young of the city. The construction of the subject on agricultural youth to the contact with the land and the work in familiar agriculture were one strong expression identified in this research, exactly leading in consideration that nor all possess the desire to remain young agricultural , or at least young agriculturists. For the young, agricultural being is express through not only the contact with the agricultural work, but also the process of sociability, formation of affective bows, possibilities of new learnings, valuation of the agricultural way and its potentialities, of that the corporeal property and cultural is possible to be young in the agricultural way with access, historicamente denied

A ética econômica das classes trabalhadoras: a gramática social do comportamento econômico da nova pequena burguesia comercial de Natal/RN

Rogram relying on sociological interface between Economic Sociology, Sociology of Moral Theory of Socialization and Social Stratification, this dissertation research makes use of theoretical contributions Luic Boltanski, Charles Taylor, Axel Honneth, Pierre Bourdieu and Bernard Lahire to problematize the generally about the physical and symbolic production and social reproduction of the type of "economic ethics" predominant in the new petite bourgeoisie Brazilian. In other words, the goal is to explain and analyze the objective conditions (economic needs and moral grammar) and intersubjective (modes of socialization and social networks) and update the social genesis and contextual transcontextual beliefs, biases, inclinations and cultural regularities observed the economic behavior of individual profiles for the fractions of the urban petty bourgeoisie and commercial upward Natal / RN. With regard to methodological strategies adopted in data collection will be conducted qualitative interviews (semistructured) and ethnographic notes. In turn, the analytical treatment of the collected empirical content is based on the approach dispositionalist (Pierre Bourdieu, Loïc Wacquant and Bernard Lahire) that emphasizes the study of the past embedded agents and the different contexts of incorporation / activation / inhibition of "provisions" individual cultural

Tecendo os fios de rede: juventude e produção de si em projetos sociais.

The study is about youthful subjectivities in quarters, of the West Zone of Natal-RN, marked for lacks and contingencies that constitute the everyday life of the social existence of its young inhabitants. For this purpose the researchers selected two youth groups: the Association of Youths Constructing Dreams (in the quarter of Felipe Camarão) and Lelo Melodia Crew (Quarter of Guarapes). Both are articulated through the strategy of coalition in regional and national nets. The hypothesis is that inside the groups and nets new youthful citizens arises. That would be a change in the representation of poor youth: from 1980 s street children - young whose social stigma associated poverty and crime to late 1990 s kids of project (pointing their trajectory in social projects) or, in present days, called as young peripherals - for the enrollment in cultural movements, as the hip hop movement - These new young citizens are contributing to new social imagery significations on poor youths. The methodology encloses: a) focal group; b) participant research analyzing the making arts (ways to think, social daily practices, actions engaged in a diversity plans) of youth groups; c) life stories of some of the youngs produced in workshops; d) not structuralized interviews. d) several documents of the groups; e) local and national surveys. Results emphasize a feeling of opening to a project of autonomy in relation to a social system that leaves them in a situation of social precariousness. Conclusion remarks that such practices of the youthful groups through the art, leisure, sport and culture unfold politics effect so that can point innovative forms of politics participation on the part of this specific segment of poor youths of Brasilian country, although conflicts and paradoxes crosses individual citizens, youth groups and youth nets.

O tempo das brincadeiras : memória, turismo e tradição em Barra do Camaratuba PB

Barra do Camaratuba belongs to Mataraca city, nearby the boarder between Paraíba and Rio Grande do Norte states. It was the chosen community to develop this research, objectifying to study the set of practical of the cultural manifestations and the implications of the local tourist activity, considering the cultural dynamics. We tried to reconstruct stories from the narratives of the oldest inhabitants, natives, among others that they had lived, some how, individual and collective experiences related to the popular tricks and the traditional parties, considering what they speak and imagine about their experiences and its culture. The Lapinha, the Pastoril, the viola s songs, the Balls of Concertina, the João Redondo, the Ox of Kings, the wheel of Coconut were common practical perceivable through the communitarian bonds. Among these manifestations, the only one that resisted for a longer time was the wheel coconut. The São Pedro s fest is another popular manifestation that appears on the current scene like the padroeiro party, while others cultural practical compose the spectacle s scenery. These questions cover many of the narratives of the interviewed ones in the interlaced thing between memory, tourism and tradition. Therefore, we tried to build our research from the memory, participant observation, orality, techniques of the life history, personal depositions, among others basic methods for the reconstruction of a collective memory . Speaking about the past of Barra do Camaratuba is to live again the parties, the blood relations, the terço , the work in the roçados , in the flour house, the fishing, the leisure and the habits of the daily life. In this community, there is the presence of conflicts of social and cultural order, caused for the hegemonic classes that sponsor the parties. In the padroeiro party we perceive that the mercantile logic has started, very recently, to transform the religious factor into an excuse to put into motion the local economy. This way, a community originated from artisan fishers and agriculturists, having the fishing practical as a way of subsistence and the tricks as a reference, they had started to compose a new social picture with the arrival of the others and with the presumption and recent tourist development. We perceive social, environmental and cultural impact transformations, exemplified by a non planned activity or a predatory tourism. The changes will always be pointed and compared with other passing in a sphere of relations lived by the natives, local players and fishers

Mulheres professoras: memórias da organização docente

Se estudia el Movimiento de las Profesoras Primarias de la Red Estadual de Enseñanza, en Salvador/BA como un movimiento social responsable por la creación de la entidad representativa de la categoría la Sociedade Unificadora de Profesores Primários (SUPP). Se parte del presupuesto de que los intereses en la valorización profesional constituyen factores fundamentales para su eclosión. Se recurre a un referente teórico para sedimentar la investigación empírica realizada a través de las profesoras primarias que participaron del Movimiento; una vez que reúne recuerdos individuales y colectivos. Se abordan las condiciones sociales, políticas, económicas y educativas que viabilizaron el surgimiento de dicho movimiento y se delimita el intervalo temporal entre 1947 al 1951. Se destaca que fueron necesarios hacer recortes históricos, los cuales han antecedido y proseguido a ése período, en función al relieve del contexto histórico-social para la comprensión de lo que fue y dónde se ubicaba el objeto de la investigación. Se identificaron tres marcos: el primero se refiere a las motivaciones en defensa de la valorización profesional, situado en un contexto de reformas educativas y pensamiento democrático; el segundo vinculado a la creación de la entidad representativa, fomentando por la necesidad de creación de una institución representativa que pudiese resguardar la categoría. Por lo tanto, se delinea la construcción histórica del Movimiento de las Profesoras Primarias, utilizando las categorías de docencia y movimiento social, de forma interpretativa. Se articulan a los hechos y acontecimientos que marcaron ése movimiento y su importancia para la Historia de la Educación de Bahia. Aun que la lucha por la valoración salarial haya sido el possibilitador de la creación de la SUPP, se constato que fue una movilización política y social buscó el sentido y el significado de lo que sea docencia con acciones que intentaban la integración del profesorado primario baiano (del interior con los de la capital) y promover el desarrollo cultural aliado a la concientización de la categoría

Uniformidade de deposição da calda de pulverização de herbicidas em barra lateral protegida com diferentes combinações de pontas de pulverização

O presente trabalho objetivou estudar a uniformidade de distribuição da calda de pulverização contendo herbicidas, em culturas perenes arbustivas, utilizando combinações de pontas de pulverização em barra lateral protegida, conduzida a pequena distância do alvo, na linha de culturas perenes arbustivas. Para isso, foi desenvolvido um programa computacional que permite simular a sobreposição do leque de pulverização, da porção protegida da barra e do leque formado pela ponta de pulverização do bico mais extremo da barra, de modo diferente dos demais programas. Após a seleção das melhores combinações de pontas de pulverização por meio de simulação dos padrões de deposição da pulverização das pontas individuais e dos coeficientes de variação menores que 10%, algumas dessas combinações foram testadas em campo, aplicando-se um herbicida sistêmico (glyphosate) e outro com ação de contato (paraquat). Os resultados indicaram que o programa computacional desenvolvido pode constituir-se em um auxiliar valioso para a seleção das melhores combinações de pontas de pulverização. em aplicações tanto do herbicida glyphosate quanto do paraquat, com volumes de calda mais reduzidos,abaixo de 100 L ha-1, destacaram-se como arranjos mais eficientes: a) pontas TT110015 distanciadas de 52,5 cm entre si, combinadas com a ponta TK-0,5 na extremidade da barra a 50 cm do último bico, operando na velocidade de 5 km h-1 e pressão de 103 kPa (15 lbf pol-2), com distância de caminhamento do tronco da árvore de 20 cm ; b) pontas SMCE2 distanciadas de 15 cm entre si, combinadas com a ponta TK-0,5 na extremidade da barra de 20 cm do último bico, operando na velocidade de 4 km h-1 e pressão de 414 kPa (60 lbf pol-2), com distância de caminhamento do tronco da árvore de 30 cm ; e c) pontas TLX-2 distanciadas de 15 cm entre si, combinadas com a ponta TK-0,5 na extremidade da barra de 20 cm do último bico, operando à velocidade de 5 km h-1 e pressão de 414 kPa (60 lbf pol-2), com distância de caminhamento do tronco da árvore de 30 cm. A velocidade de deslocamento do pulverizador de 5 km h-1 proporcionou melhores condições para que os herbicidas estudados apresentassem melhor controle de plantas daninhas, quando comparada com a velocidade de deslocamento do pulverizador de 4 km h-1.

Avaliação econômica e desempenho de machos e fêmeas Canchim em confinamento alimentados com dietas à base de silagem de milho e concentrado ou cana-de-açúcar e concentrado contendo grãos de girassol

Objetivou-se avaliar os efeitos do fornecimento de dietas com silagem de milho ou com cana-de-açúcar + grãos de girassol e a influência da condição sexual do animal sobre o desempenho de bovinos jovens em confinamento e os resultados econômicos desse sistema de produção. Foram utilizados 30 animais Canchim (dez machos não-castrados, dez machos castrados e dez novilhas), com 15 meses de idade e 289 kg de peso corporal (PC), mantidos em baias individuais durante 105 dias. Todos os animais foram pesados no início do experimento e a cada 35 dias e, ao final do confinamento, foram abatidos em frigorífico comercial para realização das medidas de características de carcaça. Os machos não-castrados apresentaram maior ingestão de nutrientes em comparação às fêmeas, tanto em valores absolutos quanto em valores relativos ao PC. Os machos castrados apresentaram valores intermediários e não diferiram dos não-castrados e das fêmeas. Os machos não-castrados apresentaram maior ganho de peso diário e desenvolvimento muscular, representado pela maior área de olho-de-lombo. Também foram mais eficientes quanto à conversão alimentar e ao rendimento de carcaça. Não houve efeito das dietas sobre a ingestão de nutrientes, à exceção do EE, que foi maior para a dieta com cana-de-açúcar + semente de girassol, com mais teor desse nutriente. As dietas também não influenciaram o desempenho dos animais. A dieta com silagem de milho mostrou-se economicamente mais viável para terminação de bovinos jovens em confinamento. Os machos não-castrados são os mais adequados para exploração de bovinos jovens em confinamento, independentemente da dieta.

Modos de ser e modos de viver : a trajetória dos estrangeiros em Natal/RN

This work aims to understand the trajectory of immigrants living in Natal / RN, between the years 1990 and 2009, their motivations for this change, their sociability relations, as well as the impact of this group in Natal and specifically, in the district of Ponta Negra, where most of them established their residences or work. Considering that the historical, political, economical and social environment where these immigrants are inserted, are different from that experienced by former immigrants who came to Brazil in the late nineteenth and early twentieth centuries, a period of mass migration, it was revealed that immigration studied in contemporary Natal constitutes a new configuration (Elias, 1994). This new configuration is represented by several characteristics that distinguish this contemporary immigration, as: the relationship established by these foreigners, both with their country of origin and the destination, the formation of social networks that offer support to newcomers and those already installed, the relations of sociability with locals and a new relationship of belonging with the space, since the possibility of coming and going from one country to the other, allows a (re)production of their original ?? social and economic life in the new space. The research methodology was based on the analysis of narrative interviews, in light of the theory of Schütze (1977) in order to understand the faces of this immigration. As theoretical support for the data analysis the theories of authors such as Norbert Elias, presentedin his work about the established and outsiders, Pierre Bourdieu, and his concept of habitus, distinction and style of life, Georg Simmel, and his study of life in the metropolis, his analysis of the foreigner and his theory of sociability, among others. This study attempted to give visibility to foreigners living in Natal, who experience the dynamics of the district of Ponta Negra and reconstruct their daily relations of sociability in this space. In fact, the presence of foreigners in this urban context allows for the construction of new configurations, both in terms of the physical space of the neighborhood, which has been modified by the touristification process and the real estate market, which is molded to meet this demand, but also in their social sphere, with regard to the relations established between foreign residents and locals. In seeking to characterize these migratory experiences it could be understood that the trajectories of each foreigner is part of a broader social structure, which cannot be evaluated neither disconnected from the contexts in which they operate, nor under a single point of view
