A presente dissertação discute o devir das Organizações NãoGovernamentais no Brasil à luz de nossa matriz sócio-política bem como da própria crise civilizatória hodierna. Considerando os desafios inerentes à complexa relação Estado/Sociedade no Brasil, quer pela fragilidade tanto do atual quadro políticoinstitucional quanto da capacidade de organização e democratização da sociedade civil, bem como os imperativos político-econômicos da "nova ordem internacional", buscamos elaborar alguns cenários em que as ONG, para lograrem seus objetivos sociais e políticos, deverão passar por profundas transformações organizacionais e institucionais. À luz das contradições de um modelo de desenvolvimento, política e socialmente excludente, reiteradamente agravadas pelo avanço do neoliberalismo e pela fragmentação de uma modalidade de democracia minimalista, pensamos caber às ONG um papel significativo na mobilização e democratização da sociedade civil brasileira rumo à reconstrução de uma matriz sócio-política capaz de resgatar o povo à nacionalidade, à soberania e à justiça sócio-econômica.

O presente trabalho é resultado de pesquisa realizada a respeito das leituras brasileiras sobre a Nova Ordem Internacional. A partir da investigação em fontes históricas depositadas no Centro de Pesquisa e Documentação em História Contemporânea do Brasil (CPDOC/FGV), como os documentos textuais do Arquivo Marcílio Marques Moreira e as entrevistas de Celso Amorim, Celso Lafer, Gelson Fonseca e Luiz Felipe Lampreia, procurouse analisar as principais ideias de três personagens históricos diretamente envolvidos com a formulação da política externa brasileira no período da Nova República, mais especificamente entre 1989 e 1994: Celso Lafer, Gelson Fonseca e Rubens Ricupero. Para tanto, buscou-se destacar as principais formas de interpretação do sistema internacional alterado pelo fim do conflito bipolar com o apoio da literatura mais recente produzida na área, como os trabalhos de Odd Westad (2005), Andrew Hurrell (2001, 2007) e John Ikenberry (2005). Os dados coletados durante o processo de feitura da pesquisa permitem-nos afirmar que, no Brasil, os temas da autonomia e do desenvolvimento são resilientes. Os debates sobre autonomia e desenvolvimento, tão caros ao discurso acadêmico e político nacionalista desenvolvido nos anos 50, além de terem permanecido como preocupação de fundo nas análises dos formuladores de política externa, demonstra que, no Brasil, o discurso modernizante retomou as ideias básicas do pensamento político nativo.

A educação vem sofrendo graves, permanentes e contundentes críticas quanto a sua produtividade, eficácia e eficiência. O ataque sistemático às escolas, e em especial às destinadas à preparação de professores, e uma constante em países do Velho, do Terceiro e do Novo Mundo. Todos concordam que a função docente exige competência profissional, sendo a sua ausência a principal responsavel pelas lacunas, insuficiências e deficiências do processo educacional. Acredita-se que a situação ensino-aprendizagem proporcionada por uma atividade didática bem orientada seja um fator de suma importância para a eficácia e eficiência de um sistema de ensino. Considerando a expansão do ensino de 2o grau, que o levou a perder muito do seu caráter acadêmico e seletivo, optou-se pelo estudo da formação do professor que a ele se destina. Com a finalidade de verificar o tipo de formação que o professor de 2o grau vem recebendo e as consequências deste no seu desempenho profissional. Analisa-se criticamente a evolução histérica de sua formação, no Brasil, e procede-se a um estudo dos currículos dos cursos de licenciatura das Faculdades de Educação, ou Unidades Equivalentes, do Estado do Espírito Santo. Verifica-se que estas, de modo geral, adotam o currículo mínimo proposto pelo Conselho Federal de Educação. Sabe-se que o ensino de 2o grau, atualmente, destina-se a alunos provenientes das mais diversas classes sociais, sendo os seus objetivos bem mais amplos que antes verifica-se que as alterações curriculares limitam-se a uma improdutiva ampliação ou diminuição de carga horária e de disciplinas. Deduz-se que a Faculdade de Educação não trouxe nenhuma inovação significativa no que concerne ao currículo de formação pedagógica de professor de 2o grau,o que dá procedência às críticas negativas que a mesma vem recebendo. Recomenda-se a realização de pesquisas de campo e o estudo de propostas curriculares objetivando obter subardias para a reformulação dos currículos atuais.

O objetivo desta pesquisa consistiu em explorar os fatores comuns das visões de futuro de três segmentos da comunidade paulistana (executivos, empreendedores sociais e pensadores), especialmente no que diz respeito às possíveis alianças cooperativas entre o mundo dos negócios e a sociedade como um todo, como também as estratégias utilizadas para concretizá-las. Indagamos se, com suas experiências de vida, os sujeitos entrevistados protagonizavam suas visões de futuro; quais eram os aspectos em comum dessas visões referentes ao futuro e ao futuro dos negócios; as estratégias utilizadas para concretizar essas visões comuns, percebidas como positivas, e de que maneira podiam contribuir para o desenvolvimento de uma relação cooperativa entre os negócios e a sociedade. Utilizamos 30 entrevistas (10 em cada segmento), em amostra acidental, gravadas e, posteriormente, submetidas a uma análise segundo o referencial da Psicologia Social de Enrique Pichon-Rivière, incluindo alguns dos indicadores do processo interacional (cooperação, comunicação e telecomunicação) e da reação dos entrevistados e entrevistadores com relação aos conteúdos aplicados (transferência e contratransferência). Baseamo-nos no protocolo de Investigação Apreciativa do projeto "Business as an Agent of World Benefit" da Weatherhead School of Management e conceitos convergentes com o referencial adotado no que se refere ao interjogo entre o homem e o mundo, o protagonismo, o contar histórias, o projeto como planejamento de futuro e a criação de novas metáforas. Com relação ao futuro imaginado, encontramos como resultado unânime a preocupação com o meio ambiente, a mudança de valores (com a revisitação da noção de bem-estar, as “mortes subjetivas” por preconceito, o acolhimento expandido aos profissionais da saúde e a saúde como valor); a interconexão (presente no mundo contábil, nos modelos econômicos equitativos, na visão do administrador como estadista, na integração entre o “dentro e fora do negócio”, na consciência da riqueza como medida global e não individual, na ética, no voluntariado por consciência, no cuidado com o ambiente, consigo mesmo, com o outro e com a vida e a morte); coerência, vínculo e escuta (com foco na qualidade das relações e não na tecnologia, no honrar o próximo, no compartilhamento de experiências, na mão dupla entre negócios e comunidade, no bom trato para com as crianças e adultos), inclusão/exclusão (com a criação de espaços públicos intencionalmente inclusivos e a real inclusão dos excluídos na empresa); a educação (através do raciocínio que lide com a linearidade vigente e estimule pensar na complexidade, do reconhecimento de aspectos saudáveis e construtivos no cotidiano, e da formação que abrange gerentes, empreendedores e comunidade, incluindo conhecimento, ética e gratidão); interioridade (alma do negócio, intuição, transcendência como diferencial influindo em uma nova percepção de lucro, sacralidade da vida, encontro consigo próprio); lucro (revisão desse conceito com foco na vida, no bem-estar, no enraizamento das pessoas); consumo/consumidor (com relação à mudança na forma de analisar investimentos inteligentes, uma nova visão de pobreza); longo prazo (ligado à sustentabilidade, à autovalorização das pessoas e à educação dos funcionários). Há muitas estratégias atuantes nos diferentes segmentos, as pensadas são: a intencionalidade de inclusão em espaços públicos por diversos agentes, a revisão do conceito de bem-estar, os benefícios compartilhados, a inclusão mais precoce do jovem no mundo dos negócios e não como forma de exploração, o incentivo às atitudes de liderança nos jovens para o novo mundo e o longo prazo, como tema a ser mais aprofundado. Quanto à relação entre negócios e sociedade parece não haver clareza entre os segmentos quanto ao papel desempenhado pelas empresas, pelas ONGs e pelas comunidades. Surgem pontos como a necessidade da expansão de idéias inovadoras por meio de instituições sem fins lucrativos, do fortalecimento da sociedade civil, de um novo conceito de organização social, das ONGs não serem mais necessárias, das comunidades solidárias como instituições de direito e da ampliação do sentido da responsabilidade social estendido ao ecossistema.

Both the end of the twentieth century and the beginning of the twenty-first century have been characterized as a period of major political, economic, social and cultural transformations. Two of the major consequences of the political-economical crisis of the end of last century are the restructuring of capitalist production, and the consolidation of neoliberalism as a worldwide phenomenon. This new world political-economical scenario has influenced, in a dialectic way, the contemporary urban development. In that sense, "new" spatial processes and new paradigms in both urban management and urban planning have gained shape. In this context of urban transformations, the central areas of western cities, also known as historic centers, are being increasingly (re)valued. Since the Second World War, the historic centers urban areas which have great infrastructure and symbolic relevance had been undergoing a process of evasion of population and activities, undeniably linked to the neglect of government authorities. However, in recent decades, the question of historic centers rehabilitation has acquired a growing interest, academically and in political agendas. The object of this dissertation is to focus on how the government of each Brazil and Portugal has dealt with the issue of historic center rehabilitation through programs of urban rehabilitation

Leishmaniasis are endemic diseases wild spread in the New and Old World, caused by the flagelated protozoan Leishmania. In the New World, the distribution of different forms of leishmaniasis is mostly in tropical regions. In the State of Rio Grande do Norte, Northeast Brazil, 85% of the captured sand flies fauna is Lutzomyia longipalpis. The distribution of the sand fly vector in the state overlaps with the disease distribution, where the presence of sand flies is associated with presence of animals shelters. The aim of this study was to analyse the blood meal preference of sand flies vector from the genus Lutzomyia spp. in laboratory conditions, to verify the vector life cicle at different temperatures sets and to identify the main blood meal source in endemic areas for visceral leishmaniasis (VL) at peri-urban regions of Natal. Sand flies samples were collected from the municipalities of São Gonçalo do Amarante and Nísia Floresta where female sand flies were grouped for the colony maintenance in the laboratory and for the analysis of the preferred source of sand fly blood meal in natural environment. The prevalence of blood meal preference and oviposition for the females sand flies was 97% for Cavia porcellus with oviposition of 19 eggs/female; 97% for Eqqus caballus with 19 eggs/female; 98% for human blood with 14 eggs/female; 71.3% for Didelphis albiventris with 8.4 eggs/female; 73% for Gallus gallus with 14 eggs/female; 86% for Canis familiaris with 10.3 eggs/female; 81.4% for Galea spixii with 26 eggs/female; 36% for Callithrix jachus with 15 eggs/female; 42.8% for Monodelphis domestica with 0% of oviposition. Female sand flies did not take a blood meal from Felis catus. Sand flies life cycle ranged from 32-40 days, with 21-50 oviposition rates approximately. This study also showed that at 32°C the life cycle had 31 days, at 28° C it had 50 days and at 22°C it increased to 79 days. Adjusting the temperature to 35°C the eggs did not hatch, thus blocking the life cycle. A total of 1540 sand flies were captured, among them, 1.310 were male and 230 were female. Whereas 86% of the sand flies captured were Lu. longipalpis as compared to 10.5% for Lu. evandroi and, 3.2% for L. lenti and 0.3% for Lu whitmani. The ratio between female and male sandfly was approximately 6 males to 1 female. In Nísia Floresta, 50.7% of the collected females took their blood meal from armadillo, 12.8% from human. Among the female sand flies captured in São Gonçalo do Amarante, 80 of them were tested for the Leishmania KDNA infectivity where 5% of them were infected with Leishmania chagasi. Female Lutzomyia spp. showed to have an opportunistic blood meal characteristic. The behavioral parameters seem to have a higher influence in the oviposition when compared to the level of total proteins detected in the host s bloodstream. A higher Lu. longipalpis life cycle viability was observed at 28°C. The increase of temperature dropped the life cycle time, which means that the life cycle is modified by temperature range, source of blood meal and humidity. Lu longipalpis was the most specie found in the inner and peridomiciliar environment. In Nísia Floresta, armadillos were the main source of blood meal for Lutzomyia spp. At São Gonçalo do Amarante, humans were the main source of blood meal due to CDC nets placed inside their houses

The present work, based on the methodological principles of the Comprehensive Discourse Analysis, aimed, through the speech of twelve newly arrived students at the Pedagogy course of the Federal University of Rio Grande do Norte, to understand the moment students start university. It also aimed to analyze the relationship between the schools they were coming from and university entrance as well as the relationship between university and their new students. In the first part of the work, which focused on school knowledge, a comprehensive listening of the speeches of the students led primarily to a distinction, established by the students, between public and private schools, a distinction especially based on the view of superiority of private schools against public ones. The abovementioned interpretation is found in the discussion of the structural duality of Brazilian education which, historically, offers different pedagogical appliances among students of more priviledged social classes and those who come from lower levels of society. The overcome of this duality, aspired by the Brazilian Constitution of 1988, was stopped by the advent of a new economic model neoliberalism, which reinforced the differences between public and private when it prioritized the market on the economic, political and social relations, including educational projects. Impoverishment of public institutions and pauperization of the work of professors affected also the relationship between teachers and studens at the current institution. This is how the teacher becomes the greatest villain at the public management system. All of these references concerning differences in the quality of teaching at public and private schools, expressed by the students interviewed, however, were centered in the preparation for the entrance exam, called vestibular, thus showing a view that the relationship between the student and the school he came from is of a propedeutic kind and even so, reduced to a preparation for an entrance exam. In the second part of the work, which analyzed the relationship between newly arrived students and their university, it was noticed that the latter represents a whole new world. This world is seen as the change at the student´s social statute for now he is grown, takes more responsibilities and is socially respected. This change of attitude established by society and the discovery of a new world which requires more independence from the students, creates in them feelings of pride and fear and they feel insecure when it comes to making decision in the campus because now their decisions deliver a greater load of responsibility. This is when students understand they need to develop autonomy, which is seen, in this work, as the capacity to make conscious decisions. Nevertheless students expressed an understanding of autonomy as something that comes as a gift for those who enter university and not as a process that is constructed from social experiences. For these students, the need to be autonomous refers to the relationships with their teachers and the search for information. This search, however, is also related, according to interviews, to public school financial cuts, which penalize university, and to the lack of employers

In this research, we reflect on Body and Poetry: for an Education of the senses. This piece of work has as its objective the comprehension of the body and poetry s interlacement, for an education of the senses, starting from the experience of the Being in the world. With this purpose, we search to understand the poetic creation as the corporal transubstantiation by means of the senses, which is realized in the creative expression and manifests itself in the body language, opening ways to an education felt in the aesthetic experience. In order to comprehend the process of poetic creation, we rely on the phenomenological method of the lived world from Merleau-Ponty, philosophy, always opening forests of questionings and sprouting new doubts in search of other comprehensions about Poetry, Body and Education. These three phenomena were investigated by means of a reflection on my own life trajectory as a poet and Physical Education professor; identification and analysis of poets/reciters; sensitive experiences experience lived in Oficinas de Poesias (Poetry Workshops), held in seven public governmental schools of the State of Rio Grande do Norte and through a permanent dialogue with the works of Merleau-Ponty, Severino Antonio, Paul Zumthor, Petrucia Nóbrega, among other authors. Phenomenology and the sources investigated have permitted us to conclude that poetic creation is not a product of a divine inspiration, of a spirit come from over yonder, nor a hereditary gift, but poetry is created from a dialogue between the poet and the organic and cultural world, revealing at each experience undergone a new world of senses and meanings. It was possible to comprehend the poetic language as a synesthetic and performable manifestation, which ontologically reveals itself and hides itself at each experience, bringing new expressive clarities of the Being in the world. This piece of research has revealed us that poetry as a sensitive experience of the poetic state makes it possible a construction of a sensitive, glad and ludic knowledge for an education of the senses

In the new world order is notorious changes in social, ethical, economical and political aspects in the society, which reach incisively higher education, requiring a number of modifications and a new vision in nursing education, in order to meet the demands of the Unique Health System. Thus, the Higher Education Institutes (HEI) and teachers are invited to face new challenges and reflect on their practices, using pedagogical approaches and innovative methodologies to meet the requirements of a globalized society. This study has as an objective to analyze the perspective of teachers in what concern the pedagogical approaches used in nursing education and to identify pedagogical approaches utilized by teachers in nursing education. This is a field research of exploratory kind, descriptive, of quantitative approach. The search was conducted at the Department of Nursing of the Federal University of Rio Grande do Norte UFRN, based in the city of Natal. The population consisted of forty-six teachers. From this population was selected a sample of twenty teachers. Data collection occurred from August to September 2011, through the utilization of the technique of interview and questionnaire. The obtained data were analyzed in two moments. In the first moment, was carried out the quantitative analysis that refers to the obtained data through the interview technique, methodological procedures were submitted to the content analysis proposed by Bardin. On the second moment, concerning the quantitative analysis of the questionnaires applied to the teachers and of the identification data, which were digitized and transferred to a spreadsheet electronic of Microsoft Excel XP, tabulated and organized into tables, containing their relative and absolute frequencies. It is worth mentioning that were respected the aspects of the CNS Resolution 196/96. With regard to the characteristics of research participants, 20% were male; with a degree of titration of 55% doctorates; regarding time of service there was a greater representation from 15 to 45 years, with 45%. The results showed that 90% of teachers who participated in the research have an appropriate understanding of non-critical pedagogical approaches, only 10% had an inadequate understanding. However, 70% of teachers, despite having an adequate understanding, reported difficulties when attempting to implement these pedagogies. Most teachers, with representability of 80% consider the non-critical pedagogies relevant in nursing education, as well as critical pedagogies, being represented by 95% of teachers. It was concluded that both critical and non-critical pedagogies are in teachers practice of undergraduate nursing education. It feels like a moment of transition, since the presence of new ways of teaching as a part of this educational context, with educational models that give value to scientific, ethical and personal aspects in the educational process. The research contains limitations, however highlights the contribution of new possibilities for action, reflection on the context of performance, maximizing the pedagogical skills necessary to conduct teaching process, in line with the new educational paradigm of higher education

The aims of this dissertation is to study formation of the Dutch view seeing the colonial scenery in screens by Frans Post, as well as, to perceive a colonial world constitution through landscape paintings by him with his natural and human representation. The artist was the first to portray South American views, after he landed in Pernambuco with retinue of Dutch governor of colony, John Maurice, Prince of Nassau-Siegen. Post, by his 24 years old, was designated to represent for Dutch people their colony. The text reflects on visual construction of natural and human aspects in landscapes by Dutchman and how that aspects were included in colonizer imaginary about the strange world of America. European (Dutch) look about their conquered possessions in the New World was charged with exoticism and imagination. In order to understand that view, it`s paramount to study imaginary pictures reared by Frans Post, on his return to the Netherlands, and notions of landscape and exotic, wild and unspoiled nature which the Dutch people had when they thought about the Dutch colony in America. Our principal (visual) sources of research are six paintings: Vista da Sé de Olinda (1662), Vista das ruínas de Olinda (undated), Engenho (undated), Engenho (1660), Vista da cidade Maurícia e do Recife (1653), e Paisagem com rio e tamanduá (1649), all these canvases were painted when Frans Post returned to Europe. We seek to work through a methodology that focuses on investigation of primary visual and textual material, because these textual and pictorial representations reflect the 17th-century colonial view of colonial history themes of the - here called - Dutch America

The objective of this work is to understand some of the modifications caused for the phenomenon of the westernization in the hinterland of the Capitania do Rio Grande e in the life of the indians populations that inhabited there during the Colonial Period. We break of the quarrel of Serge Gruzinski concerning the westernization, understood while immersed phenomenon in the context of the expansion of the commercial capitalism and that, for the imposition of the culture occidental person to the alteridades of the New World, emprende the conquest of its territories, bodies and souls. The space clipping has covered the hinterland of the Capitania do Rio Grande, specifically the colonial territory of the Freguesia da Gloriosa Senhora Santa Ana do Seridó. The chosen chronological limit for the research corresponds to the Colonial Period and part of the Imperial one. However, the emphasis falls again on the period that it initiates in 1670, year of the oldest concession of would sesmaria known until the moment in the hinterland of the Rio Grande, extending itself until the decade of 1840. Sources of written by hand nature, cartographic printed and compose the used document roll: official correspondence and legislation, petitions of would sesmaria, inventories post-mortem, justifications of debt, registers of parish, maps, action civil court jurisdiction, notes of notary's office, land landmarks. We take the method, analyzed for Carlo Ginzburg, to cross these sources between itself and to detect its implied particularitities and ideas in the space between lineses, but, attributing it status to they of a colonial speech, fruit of the bureaucracy of where it was originated and of the social place of who produced it. We look for to demonstrate, throughout the work, that the phenomenon of the westernization desestruturou the aboriginal societies and its habitat, constructing, over its rubbles, a colonial territory that found in the cartography of the Freguesia de Santa Ana an efficient instrument of control of the space and the population. On the other hand, if the imposition of the culture occidental person exterminou great part of the native population that inhabited the hinterland of the Rio Grande, the remainders of these indians and the mestizos of descending them had survived in diverse ways in the freguesia: in the condition of captives of war or in regimen of servile work, as living or assistants in the farms, populations and village; rambling without route in the fields and the population spots; as mediating agents between the world occidental person and the native, exerting military or civil positions and still appealing to Justice in search of its rights of inheritance. Experiences of slavery, servitude, errância and mediation, but, also of resistance, adaptation, mestization in the Freguesia de Santa Ana

The cooperative behavior is no longer a dilemma for the theory of evolution, since there are models that explain the evolution of this behavior by means of natural selection at the individual level. However, there have been few studies on the proximal factors that interfere with cooperative behavior. In the study of the influence of cognition on cooperation, many authors have been interested in situations in which individuals decide whether to act cooperatively and select partners with different qualities to cooperate. Of the factors studied, we highlight the need for understanding the apparatus and communication between partners to the occurrence of cooperation. Recently, highlight is the proposal that the ability to cooperate would be greater in species with cooperative breeding system. Thus, the common marmoset (Callithrix jacchus) is a New World monkey which stands as a valuable species for this type of study because it presents cooperative actions in nature, such as sharing food and protection of the community territory. Our experiment investigated whether common marmosets unrelated females (n = 6) were able to cooperate using an electrical and a mechanical apparatus, if this cooperation is a byproduct of individual actions or involve social attention, if it occurs inter-individual variation in the use of devices and formation of roles (producer / scrounger) in dyads. We use the number of rewards obtained by animals (Ratio of Correct Pulls) as indicators of cooperation and glances for partners (Ratio of Correct Glances) as indicators of social attention and communication. The results indicate that the type of apparatus was not a constraint for the occurrence of cooperation between the marmosets, but still has not been verified formation of roles in the dyads. The performance of animals in the two devices showed a large variation in the learning time, not having relationship with the performance in the tests phase. In both devices the level of social glances at control phases were casually correlated with any other phase, but the data showed that there was not social attention, that is, the monkeys realized that they gave food to the partners, but the partners did

The study of manual preference is a widely used approach to investigate cerebral laterality in nonhuman primates. However, in New World primates, little is known about the ontogenesis of hand use asymmetry, in both forced and spontaneous activities, as well as how they correlate with sexual hormones. Accordingly, a longitudinal study was conducted on the manual preference of 6 female and 4 male common marmosets (Callithrix jacchus). The study included the record of forced tests to reach for the food using only one hand (forced activity) and activities such as grooming (auto and social), scratching, grasping the food and hanging, in weekly sessions from the infantile (4 months) to the early adult phase (15 months). Feces samples were also collected, at least once a week, to evaluate the level of gonadal steroids and their influence on these behaviors. In the forced activity, the results confirm the influence of the development period on manual preference during feeding, shown by the increase in lateral stability when grasping the food between the juvenile and adult phases. During this period, a sexual hormone effect on development was also observed, mainly of progesterone in females and androgen in males, but no difference between sexes was found. In the females, progesterone also influenced the manual preference index, with a proportional increase in the degree of manual asymmetry during puberty. With respect to spontaneous activities, the animals showed proportional use of both hands when scratching, hanging, holding the food and grooming. A positive correlation was also found between the preference for holding the food in forced activities and in spontaneous activities
