En este trabajo se presentan categorías para la construcción de un modelo teórico de análisis, articulado a una metodología empírica de investigación diagnóstica y para la intervención en comunidades y organizaciones. Los procesos sociales "objetivos", los conflictos y los problemas son abordados con una metodología participativa en comunidades y organizaciones, apoyadas en técnicas sociocomunicacionales. Tomamos en consideración también hipótesis y conceptos correspondientes a una visión relativamente crítica sobre la teoría del capital social, así como una propuesta teórica a desarrollar sobre procesos de acomodación, asimilación y transformación ecológica de las comunidades a las condiciones materiales, sociales y cultural-simbólicas de la vida social bajo la noción de "cultivo social"

Nossa pesquisa tem como meta verificar a influência da refeição helênica nos costumes de uma comunidade judaica do Mediterrâneo no primeiro século. Fizemos, então, um levantamento dos contatos em que a comunidade judaica, em geral, teve com a cultura greco-romana, tanto na difusão e troca de seus valores como nos espaços ocupados por ambas as culturas e suas concepções simbólicas. Em seguida, estudamos a influência da refeição grega nos escritos do Evangelho de Lucas e em Atos. Primeiramente, na leitura exegética de Lucas 24,13-53, os discípulos a caminho de Emmaús, percebemos nesta narrativa indícios de que, especialmente na cena da mesa, a refeição foi marcada pela inclusão de um estrangeiro. De certa forma, a constituição da comunidade lucana aponta, principalmente no que diz respeito a refeição, para a formação de sua identidade. Por fim, verificamos nos textos de Lucas-Atos as consequências desse contato. O material de Lucas, tanto o Evangelho quanto os Atos dos Apóstolos, apresenta narrativas que dão ênfase à mesa, portanto constatamos que o ato de Jesus estar à mesa com pessoas desqualificadas, segundo os costumes judaicos e na perspecti-va deste material lucano, mostra a influência da refeição grega na prática dos judeus seguidores de Jesus e que esta prática foi assimilada por essa comunidade nos primeiros anos de sua formação.

A dissertação analisa as relações do pentecostalismo com a sociedade de consumo e quais as influências sofridas pelo pentecostalismo a partir desse diálogo. Em um primeiro momento procuramos, em pesquisa bibliográfica, compreender as movimentações da sociedade moderna, mais especificamente definimos a chamada sociedade de consumo. Analisamos as diversas teorias sobre o consumo e buscamos estabelecer os parâmetros que regem as relações entre religião, mercado e consumismo. Em um segundo momento, entendemos a composição do que é conhecido atualmente como pentecostalismos, compreendendo quais características delimitam o pentecostalismo desde seus primórdios, e como se deu sua evolução dentro do século 20, para, a partir daí, classificar sua diversidade atual e os novos rumos tomados pelo mesmo. Estabelecemos diálogo com os mais recentes dados censitários para entender a evolução desse campo religioso no cenário brasileiro. Ainda nesse momento, qualificamos o campo etnográfico da pesquisa: localizamos a cidade de São Bernardo do Campo e o distrito do Riacho Grande, onde ocorreu a pesquisa de campo com sujeitos religiosos de origem pentecostal. Finalmente entendemos, por meio de questionários e entrevistas, quais características assumem atualmente os pentecostais e as modificações observadas em suas práticas religiosas, fruto do diálogo entre o pentecostalismo e a sociedade de consumo. Entendemos que, como consequência da relação, novas maneiras de se relacionar com o sagrado são adotadas, configurando o que definimos como novo sujeito religioso pentecostal.

Entre os veículos impressos voltados para colônias de imigrantes em circulação na cidade de São Paulo, atualmente (2005/2006), estão Mundo Lusíada (português) e Alborada (espanhol). Identificar se estes dois jornais trazem em seu conteúdo, predominantemente, assuntos que favorecem a aculturação e assimilação do estrangeiro no território receptor ou a preservação de sua identidade cultural foi o principal objetivo deste trabalho, além de apurar as características editoriais e averiguar se a relação com a comunidade em questão não é apenas uma estratégia mercadológica. O estudo foi baseado em pesquisa bibliográfica, mapeamento das principais publicações voltadas para imigrantes que circulam na capital paulista e, sobretudo, em análise de conteúdo de 12 edições do Mundo Lusíada e 11 de Alborada. Entre os resultados observados destaca-se que o conteúdo de ambos os títulos fornece elementos que propiciam um contato direto com as raízes desses grupos. Este demonstra elementos que permeiam a memória coletiva dos imigrantes luso e hispânico que vieram para o Brasil há mais de um século independentemente de essa identidade ser real. Mundo Lusíada, apesar de ser um veículo voltado para a comunidade luso-brasileira é segmentado, uma vez que, entre outros fatores, se utiliza de estrutura comercial de uma micro empresa. Já Alboradapode ser considerado comunitário no sentido de servir à comunidade atendida pela Sociedade Hispano Brasileira SHB (que o mantém) embora este caráter esteja mudando. Com relação a aspectos jornalísticos verificados nos dois jornais, estes se assemelham aos da pequena imprensa, numa mistura de amadorismo e fonte de status. No entanto, ambos têm papel relevante no fortalecimento dos laços de amizade, culturais e união dos envolvidos, bem como na celebração de suas origens.(AU)

Esta dissertação procurou apreender que consciência, ou consciências, formaram as Comunidades Eclesiais de Base CEBs com a apropriação das orientações da Educação Popular e da Teologia da Libertação durante o Regime Militar brasileiro. Entretanto, diferente da maioria dos trabalhos que se voltam a essa experiência, o estudo elaborou uma abordagem que as colocaram em prismas diversos. Focalizou, inicialmente, o momento histórico e algumas experiências nos vinte anos de regime e, em seguida, a Educação Popular e a Teologia da Libertação (teoria e prática), objetivando compreender seus projetos político-pedagógicos. A reflexão sobre a Educação Popular e a Teologia da Libertação aliada à reconstituição histórica do período forneceram o contexto no qual se inseriu a análise pretendida: a observação do fenômeno educacional numa perspectiva de micro-análise retratando os processos sociais e as experiências vividas para conhecer a consciência que emergiu de tal experiência educacional. Neste sentido, a pesquisa inferiu, por meio da análise de uma comunidade em particular, que a consciência nascida de tal prática foi de curto alcance, uma vez que os sujeitos envolvidos nesse projeto conscientizador perceberam apenas a ausência imediata de direitos.(AU)

The genus Hemidactylus Oken, 1817 has cosmopolite distribution, with three species occurring in Brazil, two of them native, H. brasilianus and H. agrius, and one exotic, H. mabouia. Considering the studies about ecology of lizards conducted in the Ecological Station of the Seridó, from 2001 to 2011, this study aimed (1) to re-evaluate the occurrence of the species of Hemidactylus in this ESEC; (2) to analyze ecological and biological aspects of the H. agrius population; and (3) to investigate the current and potential distribution of the native species of the genus in northeastern Brazil, analyzing the suitability of ESEC to this taxon. For the first two objectives, a sampling area consisting of five transects of 200 x 20 m, was inspected in alternating daily shifts for three consecutive days, from August 2012 to August 2013. For the latter objective, occurrence points of H. agrius and H. brasilianus from literature and from the database of Herpetological Collections of the UFRN and the UNICAMP were consulted to build predictive maps via the Maximum Entropy algorithm (MaxEnt). In ESEC Seridó, 62 H. agrius individuals were collected (25 females, 18 males and 19 juveniles), and two neonates were obtained from a communal nest incubated in the laboratory. No record was made for the other two species of the genus. Hemidactylus agrius demonstrated to be a nocturnal species specialized in habitats with rocky outcrops; but this species is generalist regarding microhabitat use. In the population studied, females had an average body length greater than males, and showed higher frequencies of caudal autotomy. Regarding diet, H. agrius is a moderately generalist species that consumes arthropods, especially insect larvae, Isoptera and Araneae; and vertebrates, with a case of cannibalism registered in the population. With respect to seasonal differences, only the number of food items ingested differed between seasons. The diet was similar between sexes, but ontogenetic differences were recorded for the total volume and maximum length of the food items. Significant relationships were found between lizard body/head size measurements and the maximum length of prey consumed. Cases of polydactyly and tail bifurcation were recorded in the population, with frequencies of 1.6% and 3.1%, respectively. In relation xv to the occurrence points of the native species, 27 were identified, 14 for H. agrius and 13 for H. brasilianus. The first species presented restricted distribution, while the second showed a wide distribution. In both models generated, the ESEC Seridó area showed medium to high suitability. The results of this study confirm the absence of H. brasilianus and H. mabouia this ESEC, and reveal H. agrius as a dietary opportunist and cannibal species. Further, the results confirm the distribution patterns shown by native species of Hemidactylus, and point ESEC Seridó as an area of probable occurrence for the species of the genus, the establishing of H. brasilianus and H. mabouia are probably limited by biotic factors, a fact yet little understood

Many species have specialized to live in the most varied existing environments showing the remarkable adaptability of the microbial world the most diverse physicochemical conditions. Environments exposed to natural radiation and metals are scarce around the world, presenting a microbiota still unknown. With a total number estimated between 4 and 6 x 1030 microrganisms on earth, they constitute an enormous biological and genetic pool to be explored. Metagenomic approach independent of cultivation, provides a new form to access to the potential genomic environmental samples becoming a powerful tool for the elucidation of ecological functions, metabolic profiles, as well as to identify new biomolecules. In this context, the genetic material of environmental soil and water samples from Açude Boqueirao Parelhas-RN, under the influence of natural radiation and the presence of metals, was extracted, pirosequencing and the generated sequences were analyzed by bioinformatics programs (MG-RAST and STAMP). Taxonomic comparative profiles of both samples showed high abundance of Domain Bacteria, followed by a small portion attributable to Eucaryota Domains, Archaea and Viruses. Proteobacteria, Actinobacteria and Bacterioidetes phyla showed the greater dominance in both samples. Important genera and species associated with resistance to various stressors found in region were observed. Sequences related to oxidative and heat stress, DNA replication and repair, and resistance to toxic compounds were observed, suggesting a significant relationship between the microbiota and their metabolic profile, influenced by regional environmental variables. The results of this study add valuable and unpublished data on the composition of microbial communities in these regions

Environmental degradation is a global problem that particularly affects areas subject to seasonal climatic variations, such as the brazilian semiarid region, namely the Caatinga Domain. Combined with other negative factors, such as natural resource misuse and disorderly land occupation, the consequences of Environmental Degradation have challenged science in the quest for addressing the resulting social and environmental problems. Accordingly, Environmental Perception methodology, by analyzing the concepts, attitudes and values, (especially those pertaining to environmental conservation) represent an important tool in studies that address the relationship between the environment and human actions. Sustainability Indicators are also relevant tools to assess the possible causes and consequences of environmental problems. Among several Sustainability Indicators available, the PressuresState-Impact-Response (PSIR) method is an analytical tool that permits the grouping of factors affecting sustainability as well as their consequences for nature and human health, and thus indicate mitigating actions for society and the public authorities. From this perspective, three areas of Caatinga were studied in Rio Grande do Norte state: Seridó Ecological Station (ESEC), Municipality of Serra Negra do Norte; Private Natural Reserve Stoessel de Brito (PNRSB), Municipality of Jucurutu; and part of the Serra de Santana, Municipality of Tenente Laurentino Cruz. The areas are both legally protected and unprotected and subject to diferent management protocols, though their share the common characteristic of human misuse of natural resources. In this scenario, this thesis´ main goal was to introduce the rural communities into the conservation process, using the results of Environmental Perception of such communities, combined with the analysis of the sustainability of municipalities through PSIR. Information on Environmental Perception was obtained from primary and secondary data from previous studies carried out in the ESEC Seridó and PRNP Stoessel de Brito. Additional data was obtained through direct observation and interview forms applied to rural communities in the Municipality of Tenente Laurentino Cruz. The results showed that respondents possessed a broad knowledge regarding environmental degradation, its causes and consequences for the caatinga biome. PEIR analysis showed that environmental degradation was smaller in countries with protected areas, as compared to those without. The population´s knowledge about environmental degradation and their acceptance of conservation units, as showed by Environmental Perception Analysis, coupled with the results of PEIR, suggest that those attitudes may foster actions aimed at reduction of environmental degradation in the Caatinga domain

The Caatinga and Atlantic Forest exhibit great species richness, which can attend requirements for various uses. Considering the current level of degradation of vegetation in Rio Grande do Norte, and the increasing use of exotic species, it is urgent to perform actions for the conservation of these biomes. From this perspective, using native plant species in the urban forestry becomes an instrument for the conservation and enhancement of local biodiversity. In this context, the general objective of this study is to gather and provide information about the ornamental native tree species in the state in order to promote and disseminate their use in urban areas. Specific aims of this work are: (1) evaluate and verify the demand and maintenance costs of native and exotic urban forestry, comparatively, with data obtained in the state (Cap. 1); (2) Provide a ornamental native tree species list in the state, including species already widespread use and suggesting new elements with ornamental potential (Cap. 2); and (3) produce a guide of native tree species as a means of disseminating the results obtained in a way accessible to the society. Analysis of maintenance of urban trees was performed at the UFRN's Central Campus, and the ornamental native tree species survey was carried out through literature survey combined with expeditions to forest fragments in the state. As a result, it was obvious that the maintenance of native vegetation resulted in lower costs and least demand for services highlighting the visible advantage in using a afforestation with regionalized floristic composition. The survey of ornamental native tree species led to the selection of 95 species belonging to 30 families, 17 species (17.35%) occurring exclusively in the Caatinga, 27 species (25.55%) in the Atlantic Forest and more than half (55.10%) occurring in both biomes, which provides a good selection available for the composition of urban forestry, both for cities located in the area of Atlantic Forest (81 spp.) or for those located in the Caatinga (71 spp.). From these results, a guide for the recognition and cultivation of native ornamental trees was prepared, consisting in the initial step in the enhancement of existing floristic potential value with the aim to assist in the development of a regionalized perspective of urban environmental management in the state

The Amazon savannas occur as isolated patches throughout extensive areas of forest in the states of Amapá, Amazonas, Pará, and Roraima. There is a considerable variation in the composition of anuran assemblages in the localities and phytophysiognomies of Amazon savannas and given the absence of studies on reproductive behavior, a systematic and geographically wide sampling has been carried out in the Amapá savanna, located in the Eastern Amazon. The study was conducted in a savanna area in the state of Amapá to examine the composition, ecology, and reproductive behavior of anuran amphibians. We carried out 24 field trips in each phytophysiognomy (gramineous-woody savana, gramineous-herbaceous-woody savana, park savana, and arboreal savanna); for analysis of reproductive behavior observations were made during the period January to December 2013, lasting four consecutive days. Samples were collected by active and acoustic search along 20 plots of 100x50 meters. Twenty-one anuran species were recorded, of which four are new records for the state of Amapá: Dendropsophus walfordi, Scinax fuscomarginatus, Pseudopaludicola boliviana e Elachistocleis helianneae. The KruskalWallis ANOVA revealed significant differences between richness and species diversity in the phytophysiognomies (p < 0.05). The Bray-Curtis similarity coefficient divided the phytophysiognomies into three groups: arboreal savana, gramineous-woody savanna and gramineous-herbaceous-woody savanna, and park savanna. According to the non-metric multidimensional scaling, the structure of the anuran community resulted in a separation into three phytophysiognomies, with significant differences in the structure of communities (ANOSIM, R = 0.823; p < 0.001). In the study of community ecology, the results obtained for spatial, temporal, and trophic niche breadth suggest that the assemblage of anurans of the Amapá savanna is not composed of predominantly generalist species. Also, the presence of other specialist anurans may explain the processes of speciation associated with the isolation of habitats, resulting in heterogeneity and spatial discontinuity in the phytophysiognomies with open formations. The null model analysis revealed that the community is structured based on temporal and trophic niche, indicating a significant influence of contemporary ecological factors on the assemblage. The absence of structure based on spatial niche might be explained by the spatial segregation in the distribution and occupation of anurans in the different phytophysiognomies of the Amapá savanna. Regarding the reproductive behavior of anurans, 11 species were classified as having a long breeding season, intrinsically associated with the rainy season and the reproductive mode of most species that lay egg clutches in lentic water bodies. Six reproductive modes were recorded and parental care was observed in Leptodactylus macrosternum and L. podicipinus, whose reproductive mode is characterized by foam nests. Regarding behavioral reproductive strategies, calling males were observed in all species of anurans, satellite males were recorded only for D. walfordi, Hypsiboas multifasciatus, S. nebulosus and S. fuscomarginatus; active search for females was observed for Phyllomedusa hypochondrialis and L. fuscus, and male displacement was recorded only for Rhinella major and R. margaritifera. Of the reproductive behaviors observed, throat and vocal sac display is associated with courtship and territorial behavior exhibited by males. In addition to courtship behavior, visual signals associated with courtship strategies were recorded for the anurans of the Amapá savanna.

Las comunidades colaborativas, donde grandes cantidades de personas colaboran para la producción de recursos compartidos (e.g. Github, Wikipedia, OpenStreetMap, Arduino, StackOverflow) están extendiéndose progresivamente a multitud de campos. No obstante, es complicado comprender cómo funcionan y evolucionan. ¿Qué tipos de usuarios son más activos en Wikia? ¿Cómo ha evolucionado el número de wikis activas en los últimos años? ¿Qué perfil de actividad presentan la mayor parte de colaboradores de Wikia? ¿Son más activos los hombres o las mujeres en la Wikipedia? En los proyectos de Github, ¿el esfuerzo de programación (y frecuencia de commits) se distribuye de forma homogénea a lo largo del tiempo o suele estar concentrado? Estas comunidades, típicamente online, dejan registrada su actividad en grandes bases de datos, muchas de ellas disponibles públicamente. Sin embargo, el ciudadano de a pie no tiene ni las herramientas ni el conocimiento necesario para sacar conclusiones de esos datos. En este TFG desarrollamos una herramienta de análisis exploratorio y visualización de datos de la plataforma Wikia, sitio web colaborativo que permite la creación, edición y modificación del contenido y estructura de miles de páginas web de tipo enciclopedia basadas en la tecnología wiki. Nuestro objetivo es que esta aplicación web sea usable por cualquiera y que no requiera que el usuario sea un experto en Big Data para poder visualizar las gráficas de evolución o distribuciones del comportamiento interno de la comunidad, pudiendo modificar algunos de sus parámetros y visualizando cómo cambian. Como resultado de este trabajo se ha desarrollado una primera versión de la aplicación disponible en GitHub1 y en http://chartsup.esy.es/

En los últimos años han aparecido nuevas formas de turismo más sostenibles, donde existen elementos relacionados con el descanso, el disfrute y la protección del medio ambiente o el conocimiento de la cultura local, a través de políticas que favorecen la sostenibilidad del destino. En este sentido, el ecoturismo se configura como una tipología turística que se desarrolla en contacto con la naturaleza. Este turismo ayuda a mejorar el desarrollo socioeconómico de las comunidades locales, a la vez, que fomenta la conservación de los recursos naturales y el respeto hacia el medio ambiente. Aunque, esta tipología de turismo también genera importantes impactos negativos. El objetivo principal de esta investigación es analizar los impactos socioeconómicos, culturales y medioambientales percibidos por el ecoturismo por parte de los residentes de comunidades rurales de República Dominicana. La técnica de recolección de datos utilizada ha consistido en un cuestionario. Entre las principales conclusiones, cabe destacar que actualmente no se perciben impactos negativos, pero si hay una serie de elementos que hay que ir considerando, con la finalidad de que no se conviertan en un impacto a corto plazo para la comunidad rural.
