Lógica por trás dos contratos sociais

Natural selection shapes body and behavior of each species. For primates, the social environment constituted one of the greatest selective pressure for the development of their cognition. When we consider gender differences, we see that sexual selection also operates through different selective pressures for men and women not only in physical terms but in terms of cognitive skills. Among these, the primary cognitive abilities - that emerge naturally - and secondary - that rely on an artificial environment for learning - develop differently for each sex, making them suitable for specific tasks in different capacities. Previous studies utilized the Wason Selection Test a conditional logic tool - to measure, among several other things, the ability to recognize violation of rules in abstract contexts and social contexts. Subjects generally had better performance in the latter, however, in these studies possible differences motivated by learning in formal logic or genre were not considered. Our study investigated these two variables, as well as the time spent to solve each task. Furthermore, we used an index to take into account the rights and wrongs of the participants in tasks. We realized that although learning in formal logic does not bring significant differences in solving tests, the gender differences are strongly observed when we consider the social contexts and abstract. Women perform better in social tasks. This can be explained due to different sexual selective pressures for this gender in terms of one-on-one relationships within the group. Men are better at tasks of abstract context and this is probably due to the same reason. Their capabilities for territory defense, habitat navigation and forming coalitions depends on primary cognitive abilities that support secondary cognitive skills of abstraction. Thus, gender differences are a factor to be taken into account in controlling future experiments with the same tool

Por trás das grades :reflexões sobre a experiência do ser apenado na situação de privação de liberdade

This research has resulted of investigations appeared from our work experience as psychologist in a prison of the state Rio Grande do Norte. It deals with the meeting with prisoner in the search for the rescue of the human being dignity, discovering the being that finds annulled by backwards of the prison. The current debate on the prisoners in Brazil has as focus the creation of efficient strategies in the combat to the criminal acts, not being worried in understanding the historical and social conditions in the context in which such acts develop. Our objective was to reach an understanding of the experience of the prisoner in the situation of freedom deprivation in Natal (RN) city. Its significant social relevance meets in emphasized thematic which intends to be revealing of the not-said one of these citizens. The epistemological space and the vision of adopted human being support in the humanist ideas of the Centered Approach in the Person and construct self, central nucleus of the personality theory proposal by Carl Rogers. We opt to the phenomenological method as way of access to the singularity of the experience of each one of the participants, supporting us in the strategy of the narrative as expression of the lived world. The results had pointed that the investigated experience is through suffering, that is, the way to be in the world of prisoner in the situation of freedom deprivation is felt by him/her as difficult to support. This reality is had by him/her as difficult to control, having a negative emotional repercussion for the self, leading the citizen to the alienation of his/her existential flow in these circumstances. The reflections produced in this work take us to consider that the punishment practices on behalf of a normalization of the behavior, linked to the recovery idea, do not meet to the intention of the arrests, that come demonstrating to the inefficacy of the objectives shown in the law as well as the loss of the human being dignity

Participação de moradores no programa de coleta seletiva em três bairros de Natal/RN: explorando determinantes psico-socio-ambientais

The general purpose of the study was the analysis of residents' participation in the program of door-by-door collection of recyclable residuals in Natal, Rio Grande do Norte. Even though the conception of such program by municipal managers was basically aimed at providing job opportunities and income for the collectors, the main objective of the investigation was to verify whether residents' participation could be attributed to their environmental commitment. Data collection involved three municipal districts and was performed in three stages, with complementary methodological strategies (observation, questionnaire, and interview), and characterized by selfevaluation, by residents, and hetero-evaluation, by collectors. Social, demographic, situational/contextual, and dispositional data were identified to help in the analysis of residents' adherence to the program. Separating and delivering recyclable residuals was the most frequent type of residents' participation, which demonstrates their low level of appropriation of decisions related to the program, taking part on it as passive agents. Two forms of motivation towards participating in the program were found: environmental and social. Despite the first being more frequent, it was associated to lack of environmental awareness related to the process, which may very well imply a mere reproduction of pro-environmental discourse. Motivation towards social issues was strongly connected to philanthropic forms of help. Knowledge was revealed as na important predictor for participation, as well as social networks, formed by neighbors, relatives and friends. Despite the social emphasis in the design of the program, it is possible to conclude that some residents also perceive its environmental benefits, possibly as consequence of a knowledge originated outside the program. Initiatives of environmental education should be promoted in order to minimize the allegation of lack of knowledge as justification for non-participation. Similarly, actions to put together municipal management and population would be welcome, to promote joint decisions towards sustainable styles of life

Uso de câmara úmida em enxertia convencional de maracujazeiro-amarelo sobre três porta-enxertos

A propagação do maracujazeiro através da enxertia poderá ser a solução para o controle de doenças do sistema radicular. Assim, com o objetivo de avaliar o desenvolvimento e a sobrevivência de plantas enxertadas de maracujazeiro-amarelo (Passiflora edulis Sims) em três porta-enxertos, utilizando-se de câmara úmida, instalou-se este experimento em um viveiro de mudas no município de Adamantina-SP, no período de dezembro de 2005 a abril de 2006. O delineamento experimental utilizado foi em blocos ao acaso, em esquema fatorial 3 x 2, com quatro repetições e 10 plantas/parcela. Os fatores avaliados foram três porta-enxertos (Passiflora edulis, P. alata e P. gibertii)em dois ambientes (com e sem câmara úmida). Foi utilizada a enxertia convencional pelo método de garfagem tipo fenda cheia. Avaliaram-se a sobrevivência e a altura dos enxertos, o diâmetro do caule do porta-enxerto e do enxerto, o número de folhas e a fitomassa seca da parte aérea e das raízes. Verificaram-se melhores resultados com os porta-enxertos P. edulis e P. gibertii, superiores ao P. alata em todas as variáveis estudadas. Os maiores índices de sobrevivência foram observados em P. edulis e P. gibertii, com 100% e 98,8%, respectivamente. Apesar de o P. alata ter-se mostrado inferior, é viável o uso deste material como porta-enxerto para o maracujazeiro-amarelo. O uso da câmara úmida favoreceu o pegamento dos enxertos em P. alata.

Uso de câmara úmida em enxertia hipocotiledonar de maracujazeiro-amarelo sobre três porta-enxertos

Com o objetivo de avaliar o desenvolvimento e a sobrevivência de plantas de maracujazeiro-amarelo (Passiflora edulis Sims) enxertadas sobre três porta-enxertos com uso de câmara úmida, instalou-se este experimento em um viveiro de mudas no município de Adamantina - SP, no período de dezembro de 2005 a abril de 2006. O delineamento foi em blocos ao acaso, em esquema fatorial 3 x 2, com quatro repetições. Os fatores avaliados foram três porta-enxertos (Passiflora edulis, P. alata e P. gibertii) em dois ambientes (com e sem câmara úmida). Foi utilizada a enxertia hipocotiledonar pelo método de garfagem tipo fenda cheia. Avaliaram-se a altura das plantas, o diâmetro do caule do porta-enxerto e do enxerto, o número de folhas, o comprimento do entrenó, a porcentagem de sobrevivência das plantas e a fitomassa seca da parte aérea e das raízes. Observou-se que o método de enxertia utilizado foi bem-sucedido para as três espécies de porta-enxertos estudadas. P. gibertii e P. edulis proporcionaram melhores resultados como porta-enxertos. O porta-enxerto P. alata proporcionou menor altura de planta, menor diâmetro do enxerto e do porta-enxerto e menor índice de sobrevivência. O uso da câmara úmida não favoreceu nenhuma das variáveis estudadas.

Desenvolvimento e produtividade do maracujazeiro-amarelo enxertado em três porta-enxertos

O objetivo deste trabalho foi avaliar o desenvolvimento vegetativo e a produtividade do maracujazeiro-amarelo (Passiflora edulis Sims) enxertado sobre três porta-enxertos em área sem histórico de morte prematura de plantas. O experimento foi conduzido no município de Adamantina-SP, no período de abril de 2006 a junho de 2007, adotando-se o delineamento em blocos ao acaso, em esquema fatorial 3 x 2 + 1 tratamento adicional, com quatro repetições. Os fatores avaliados foram três porta-enxertos: Passiflora edulis, P. alata e P. gibertii, em dois sistemas de enxertia, a hipocotiledonar e a convencional por garfagem tipo fenda cheia, e um tratamento adicional, sem enxertia. Utilizou-se como copa o maracujazeiro-amarelo (Passiflora edulis Sims). Avaliaram-se o diâmetro do caule do porta-enxerto, o diâmetro do caule do enxerto, o comprimento de entrenó, o comprimento dos ramos secundários, o número de ramos terciários, o número de frutos, a massa média de frutos, a produtividade e as fitomassas verde e seca das plantas. Observou-se que as três espécies estudadas podem ser utilizadas como porta-enxertos para o maracujazeiro-amarelo, com diferentes níveis de compatibilidade. P. edulis demonstrou maior compatibilidade como porta-enxerto por apresentar-se superior aos demais na maioria dos parâmetros analisados. Plantas enxertadas sobre P. gibertii apresentaram menor vigor, menor crescimento vegetativo, frutos com menor massa e menor produtividade. A enxertia hipocotiledonar resultou em maior massa média de frutos e maior produtividade no maracujazeiro-amarelo.

Características físicas e químicas de frutos de maracujazeiro-amarelo enxertado em três porta-enxertos

O mercado de frutas frescas do maracujá-amarelo valoriza a qualidade interna e externa dos frutos. Assim, este trabalho teve o objetivo de avaliar o efeito do porta-enxerto e do tipo de enxertia na qualidade dos frutos de maracujazeiro-amarelo (Passiflora edulis Sims). O experimento foi conduzido no município de Adamantina-SP, no período de abril de 2006 a junho de 2007, adotando-se o delineamento em blocos ao acaso, em esquema fatorial 3 x 2 + 1 tratamento adicional, com quatro repetições. Os porta-enxertos avaliados foram: P. edulis (maracujá-amarelo), P. alata (maracujá-doce) e P. gibertii (maracujá-giberti), em dois tipos de enxertia: hipocotiledonar e convencional por garfagem tipo fenda cheia e um tratamento adicional, sem enxertia. Utilizou-se como copa o maracujazeiro-amarelo (Passiflora edulis Sims). Avaliaram-se o comprimento, o diâmetro, a massa fresca e a classificação dos frutos no período de novembro de 2006 a abril de 2007, a massa e a espessura da casca dos frutos, o rendimento do suco, o teor de sólidos solúveis totais (SST), a acidez total titulável (ATT) e o ratio (SST/ATT) dos frutos no mês de dezembro de 2006. O diâmetro e a massa fresca de frutos obtidos de plantas enxertadas sobre P. gibertii foram inferiores em relação aos de plantas pé-franco e aos de plantas enxertadas sobre P. alata. Os maiores comprimentos de frutos foram encontrados em plantas não enxertadas. Os porta-enxertos utilizados não influenciaram no teor de SST, na ATT e no ratio. O método de enxertia não interfere no diâmetro, no comprimento, na massa fresca dos frutos, na massa e na espessura da casca, no rendimento do suco e no teor de SST.

Fungos gasteroides (Basidiomycota, Agaricomycetes) de três áreas de semiárido no Estado do Ceará, Brasil

Gasteroid fungi include several distinct lineages of basidiomycetes that were grouped by presenting some striking features in common like angiocarpic development and passive release of basidiospores. For a long period these fungi were accomodate in Gasteromycetes class. However, biochemistry and molecular studies showed the polyphyly of this group and curriently this class lies devoid of taxonomic value. These organisms influence the ecology of the various biomes, however, are poorly studied and knowledge of their diversity in neotropical ecosystems remains insufficient, despite studies that have been developed in recent years. The Brazilian semiarid region has many areas with an unexplored mycobiota. Ceará State has many areas of extreme biological importance and for this study three protected areas were chosen: Área de Proteção Ambiental da Serra da Ibiapaba, Parque Nacional de Ubajara and Área de Proteção Ambiental de Baturité. Therefore, the aim of this study was to inventory gasteroid fungi ocorring in these three areas in the semiarid region of Ceará. The expeditions, herborization and analysis of specimes were based in traditional methodology used to identify gasteroid fungi. Were identified 16 species belong to 5 families: Agaricaceae, Clathraceae, Geastraceae, Nidulariceae and Phallaceae. Morganella nuda Alfredo & Baseia is recorded for the second time in the world, Blumenavia angolensis (Welw. & Curr) Dring and Mutinus elegans (Mont.) E. Fisch. corresponds to a first record in the Brazilian Northeastern. Except for Abrachium floriforme (Baseia & Calonge) Baseia & T.S. Cabral and Geastrum lloydianum Rick, all remaining species are new records for Ceará, increasing the list of gasteroid fungi in the region of 3 for 17 species. Identified species were deposited in the collection of the Herbarium of Universidade Federal do Rio Grande do Norte. Although these areas have proved conducive to the study of gasteroid fungi, more efforts are still needed to increase knowledge of these fungi in the region

A saúde ambiental e os resíduos de serviços de saúde nos três níveis de complexidade do Sistema Único de Saúde - SUS

The environmental management in the health establishments is a reality still little explored in the health sector in Brazil, especially concerning its wastes. The management of wastes of health services is established in the valid legislation through the National Council of Environment and Sanitary Vigilance Agency (358/2005 and 304/2004 respectively). The present work is about a descriptive work about the environmental health in the health services. The used criterion was to diagnose the environmental management in twelve establishments of health inserted in the three levels of complexity of the Unique Health System (Sistema Ùnico de Saúde SUS). Among the sub criteria used the waste management is the one of bigger concern. The one referring to the water quality is considered good. The analysis of data reveals that 66% of the establishments got a poor environmental ranking, 17% critical and 17% appropriate, showing that the health establishments in the three levels of complexity of the SUS need urgent structural, environmental and educational interventions

Implicações tectônicas na hidrologia do aqüífero Barreiras e sistema lacustre do Bonfim, Nísia Floresta-RN

This MSc dissertation presents the results of a research carried out in a 500 km2 area in the Nísia Floresta county. The main goal of the research was to evaluate fault influence on hidrology features of aquifers and lakes, mainly in the Barreiras Group and in the Bonfim lake cluster respectively. The Precambrian crystalline basement is made of Caicó Complex rocks. They are capped by cretaceous sedimentary rocks and by cenozoic sedimentary rocks. Only the latter outcrop in the study area, wheareas the former are described in boreholes. Faults cut across all stratigraphic units and their main trends are NW, NE and E-W, which have been generated by E-W compression. Subordinate N-S trending faults also take place and have been generated by N-S oriented compression. Fault controlled hydrologic features are observed throughout the study area. There are sudden changes in saturated thicknesses of the Barreiras Aquifer due to vertical displacement of the Barreiras Group. The most important underground water source of the Bonfim Lake is related to abrupt thickness changes of the aquifer. In addition, the main faults control the underground drainage network and, probably, change in direction of equipotential surfaces seen on the potenciometric map. Regarding the surface hydrologic features, faults also control river and stream channels, as well as lake origin and shapes. The Bonfim Lake, in particular, has its peculiar shape, which follows NW and NE lineaments, and origin related to faulting and probably underground carstics processes

Vulnerabilidades socioambiental na zona de proteção ambiental 9, Natal/RN

This work aims to analyze socio-environmental vulnerability in the Zone of Environmental Preservation -9, located in the northern of the city of Natal / RN. This objective was outlined when we noted a large number of households (about 2000) located in an area considered relevant in terms of environmental and social conditions, notably because of the existence of lakes, sand dunes and rivers that contribute to groundwater recharge Dunas/Barreiras Furthermore, this area is widely used for agricultural activities. The methodology used during this research is accorded to the literature review about the concept of vulnerability, consultations in public agencies for data acquisition, field research and questionnaires. Data collected from each category of vulnerability (social and environmental) were tabulated, analyzed and presented as tables, maps and texts. According to theoretical concepts and methodology of Alves (2006), Cutter (1996), Torres (2000), Acselrad (2006) e Hogan e Marandola Junior (2005; 2006; 2007), the research is structured in the preparation of an environmental diagnosis of the neighborhoods of Blue Lagoon and Pajuçara and subsequent analysis of socio-environmental vulnerability in the Zone of Environmental Preservation -9, especially Area 1, 2 and 3.There was a variation in results between the social vulnerability and environmental vulnerability categories for each area of the Zone of Environmental Preservation -9. However, the crossing between the two categories above showed that Area 3 had the highest level of environmental vulnerability, followed by Area 1. On the other hand, the Area 2 was considered of minor environmental vulnerability. In this sense, this work presents relevant subsidies to the planning of public policies, to identify and characterize the critical areas with high socio-environmental vulnerability

Os farofeiros em excursão nas lagoas de Arituba, Boágua e Carcará (Nísia Floresta/RN): análise de uma outra face do turismo potiguar

This thesis analyzes another side of Potiguar tourism , the unplanned side, neglected and kept out of touristic activities: excursionism, a leisure practice enjoyed by tourists with low consumer power, and who are commonly referred by the pejorative term farofeiros (picnic lovers). The geographic research sites considered for this study include Arituba, Boágua and Carcará lakes in Nísia Florest, Rio Grande do Norte, where on Sundays and holidays the arrival of hundreds of excursionists, from around the metropolitan region of Natal, from surrounding municipalities, and neighboring States, such as Paraíba and Pernambuco, can be observed. The objective of this study is to analyze the appropriation of the physical site by the practice of excursionism, focusing on its relation to other social agents that also appropriate a designated touristic area. The theoretical discussion considers the use of the space by the touristic leisure practice and the appropriation by distinct social agents, using categories of analysis, such as, production of the space, territory and leisure. The field work was completed with interviews and questionnaires administered to excursionists, excursion organizers, local merchants, representatives of the public setor from the municipalities, and professional dune buggy drivers; besides this, photos, informal dialogue and field observations were important methodological instruments used. From the data, statistical analysis and the development of thematic maps demonstrating the established flux between excursionists and the segregated activity were done. With this research, one can affirm that the practice of excursionism is neglected by the public sector, contrary to the intention of the hegemonic agent‟s intentionality present in this touristic territory which aim at the development of a lucrative activity, geared toward tourists with greater spending power. This ignored and neglected faction of Potiguar tourism is considered poor or dirty , and generate conflicts among the distinct social agents: tourists, the market and the public sector, simultaneously peaking interest, which is then appropriated by the informal sector and formal economy. Excursionism is an expressive phenomenon, a socially relevant practice, enjoyed by citizens of the working class who, in order to have a day of leisure, use alternative consumer practices and subvert various strategies of segregation that are imposed within these tourist areas, behavior that, in part, justifies the nickname, picnic lovers , given to these tourists
