Mar cruzado e terra bilingue: uma breve abordagem sociolinguística das línguas de Cabo Verde

O objetivo da presente dissertação de Mestrado consiste em refletir sobre o conjunto das representações e atitudes dos cabo-verdianos perante as línguas: o Crioulo e o Português. Como surgiu o Crioulo cabo-verdiano (daqui em diante Ccv)? Em que medida se pode falar da sua unidade e diversidade? Qual o futuro dessa língua nacional? Como convive com a Língua portuguesa (Lp daqui para frente), a língua oficial do país? Na verdade, pretendo retratar, usando os dados de todos conhecidos, a situação sociolinguística de Cabo Verde, sabendo-se que esse Arquipélago, situado ao largo da costa ocidental da África, era desabitado até à chegada dos portugueses no século XV. Com a colonização e importação de escravos do continente, desenvolveu-se no Arquipélago uma língua crioula de base lexical portuguesa, que é hoje a língua materna da grande maioria dos seus habitantes. Este “olhar de fora” sobre a situação linguística cabo-verdiana, elaborado por um estrangeiro não-residente em Cabo Verde, fruto da investigação desenvolvida no âmbito do mestrado em Estudos Regionais e Locais, tem como objetivo questionar o presente e o futuro do convívio entre o Crioulo e o Português nessa sociedade e cultura insulares de conformação mestiça. Para o efeito, o estudo faz um levantamento de algumas questões associadas a esta área da Linguística (Sociolinguística e Política linguística) e dos resultados da investigação ressaltam o bilinguismo com diglossia e o debate aceso entre alguns intelectuais falantes do Crioulo, em torno da oficialização da língua materna em paridade com a língua portuguesa, passados que foram trinta e oito anos (1975-2014), após a independência política do arquipélago de Cabo Verde.

Transport modelling: macro and micro simulation for the studied case of Funchal

The work done in this thesis attempts to demonstrate the importance of using models that can predict and represent the mobility of our society. To answer the proposed challenges two models were examined, the first corresponds to macro simulation with the intention of finding a solution to the frequency of the bus company Horários do Funchal, responsible for transport in the city of Funchal, and some surrounding areas. Where based on a simplified model of the city it was possible to increase the frequency of journeys getting an overall reduction in costs. The second model concerns the micro simulation of Avenida do Mar, where currently is being built a new roundabout (Praça da Autonomia), which connects with this avenue. Therefore it was proposed to study the impact on local traffic, and the implementation of new traffic lights for this purpose. Four possible situations in which was seen the possibility of increasing the number of lanes on the roundabout or the insertion of a bus lane were created. The results showed that having a roundabout with three lanes running is the best option because the waiting queues are minimal, and at environmental level this model will project fewer pollutants. Thus, this thesis presents two possible methods of urban planning. Transport modelling is an area that is under constant development, the global goal is to encourage more and more the use of these models, and as such it is important to have more people to devote themselves to studying new ways of addressing current problems, so that we can have more accurate models and increasing their credibility.

Avaliação e desenvolvimento dos locais de prática de desporto de natureza e turismo ativo: estudo caso da paisagem protegida da Serra de Montejunto

As áreas protegidas, pela sua diversidade de recursos, assumem um papel relevante no contexto do desenvolvimento local atual. Para além de se constituírem como locais privilegiados de biodiversidade, são também os espaços eleitos para a recreação e lazer. Assim, estas carecem de intervenções especializadas ao nível do planeamento e da gestão, no sentido de tirar o melhor partido dos seus recursos para as comunidades locais e, ao mesmo tempo, promover a sua sustentabilidade. As atividades de desporto de natureza e de turismo ativo identificam-se como um segmento do turismo capaz de atrair cada vez mais visitantes aos espaços naturais, constituindo um fator potencial de desenvolvimento económico, especialmente para as áreas protegidas. No entanto, este potencial só poderá ser devidamente explorado se garantirmos a sua conservação e a sua sustentabilidade. A presente investigação pretendeu abordar as grandes temáticas da prática de atividades de desporto de natureza e turismo ativo em áreas protegidas. Com base nisto, este estudo caracteriza a Paisagem Protegida da Serra de Montejunto e identifica o potencial desta área protegida para a prática de atividades de desporto de natureza e turismo ativo. Posteriormente, caracteriza, avalia e classifica os locais destinados à prática de atividades de desporto de natureza e turismo ativo identificados nesta área e apresenta, por fim, propostas de (re)qualificação desta área, no âmbito do turismo, do desporto e da sustentabilidade. A metodologia utilizada incluiu diversos métodos distinguidos em cada um dos estudos efetuados. Os resultados obtidos nesta investigação podem constituir uma importante ferramenta para os processos de planeamento, gestão e desenvolvimento turístico nesta área protegida.

Relações interétnicas em conflito entre makuxi e wapixana na terra indígena Raposa Serra do Sol

This dissertation present an analysis of the interethnic conflict between Makuxi and Wapixana at the current moment in the Maloca of the Adobe, Aboriginal Land Fox-Mountain range of the Sun, in the State of Roraima. The theoretical field was boarded in the Ethnology, pursuing situations in local history, with edges in ethno-history. The research elapsed of the deepening necessity on the social relations and aboriginal politics, for the intercultural professional exercise of educator, appealing the bibliographical survey and participant comment as method; not directive interviews, photographs, filmings and daily register in of field, as techniques carried through in the period of 2006 to 2007. Although to inhabit in the same area and to establish marriages between itself, individuals and groups express tensions, aggravated with the landmark and legal recognition of the area, which generated inter dispute and intraetnias, mainly with the intrusion of farmers, rizicultores and the form of governmental influence. A relation of rivalry, individual and collective was evidenced, suggesting the strengthenig and not it fractionly, of the fights external politics, interns and in way to the cultural diversity and social adversity

Os forrós da Serra da Gameleira (São Tomé/RN) : etnicidade, festa e sociabilidade

This work intends to describe and analyze the parties of forró that happen in Serra da Gameleira, in São Tomé/RN. Serra is a divided social space: groups of different ethnic origins live together in Gameleira de Baixo, Salgadinho (or Gameleira de Cima) and Chaves Belas. They are approximately two hundred families that live exclusively from agriculture. We try to understand how the parties inform about the social organization, the ethnic composition of the families that live there and the past of Serra, through the genealogy offorró players. In the discussion, we identify the festive places: in the total, we have Five houses of forró that function regularly one of them has been described. The private and public spaces inside them are intimate related, with no clear limits between the house of forró and the residence. Each house of forró has an owner, that regularly makes the parties, mobilizing a big part of the inhabitants, and provoking the straitening of the social relations. Observing the festive sociability between different social segments, the forró appears like na element that minimizes social conflicts, providing news ways of association and cooperation in the space of Serra da Gameleira. For the collection of facts, we used the ethnographic method, through the direct observation, interviewing and documentary research. The local history is recounted following the routes of oral memory and historical documents analysis. In the end of the analysis, we concluded that music and party are elements that aggregate the different groups that live in the location and determine forms of expression of what is seen as a traditional culture

Entre o mar e estrela, um lugar para se bem viver : a problemática da expansão urbana da Cidade de Baía Formosa/RN

The urban expansion problem of Baía Formosa, a southern edge city of de Rio Grande do Norte eastern coast, which has been presented in other coast Brazilian towns, specially on those with tourist activities increase. Therefore, this situation brings huge concerns to their inhabitants, to their technical /scientific community and to the governments, because of the conflicts of interest and of the growth of urban problems that this has been created. At Baía Formosa, the situation is aggravated because the city is confined, once around it, there are large private proprieties, environmental preservation area and the sea, at the eastern edge. The objectives of this study are the analyses of this city expansion process in order to obtain adequate alternatives and defining methodology to apply in other urban nucleus that are subjected to similar situations. Of course, presents social relations, environmental conditions and promoting local population insertion should be considered in order that enjoin this process and contributing to a better social balance. This case study has used bibliography research, field data, maps and soil occupation recorders and photographs of the area, besides the primary data gathering by surveys carried out with many social actors. The present analysis shows that the urban expansion observed today is featured by a recent unsustainable model, which attacks the environment and brings either farm conflicts. On the other hand, the ecological tourism can represent an alternative in order to achieve an adequate expansion form, without forgetting the several structural parameters necessary to support the sustainable activities

Genotoxicidade e composição do material particulado emitido pela queima de Biomassa: um estudo de caso em Tangará da Serra, Região da Amazônia Brasileira

Tangara da Serra is located on southwestern Mato Grosso and is found to be on the route of pollutants dispersion originated in the Legal Amazon s deforestation area. This region has also a wide area of sugarcane culture, setting this site quite exposed to atmospheric pollutants. The objective of this work was to evaluate the genotoxicity of three different concentrations of organic particulate matter which was collected from August through December / 2008 in Tangara da Serra, using micronucleus test in Tradescantia pallida (Trad-MCN). The levels of particulate matter less than 10μm (MP10) and black carbon (BC) collected on the Teflon and polycarbonate filters were determined as well. Also, the alkanes and polycyclic aromatic hydrocarbons (PAHs) were identified and quantified on the samples from the burning period by gas chromatography detector with flame ionization detection (GC-FID). The results from the analyzing of alkanes indicate an antropic influence. Among the PAHs, the retene was the one found on the higher quantity and it is an indicator of biomass burning. The compounds indene(1,2,3-cd)pyrene and benzo(k)fluoranthene were identified on the samples and are considered to be potentially mutagenic and carcinogenic. By using Trad-MCN, it was observed a significant increase on the micronucleus frequency during the burning period, and this fact can be related to the mutagenic PAHs which were found on such extracts. When the period of less burnings is analyzed and compared to the negative control group, it was noted that there was no significant difference on the micronuclei rate. On the other hand, when the higher burning period is analyzed, statistically significant differences were evident. This study showed that the Trad-MCN was sensible and efficient on evaluating the genotoxicity potencial of organic matter from biomass burning, and also, emphasizes the importance of performing a chemical composition analysis in order to achieve a complete diagnosis on environmental risk control

Efeito da salinidade da água do mar no rendimento, composição e atividades biológicas de frações polissacarídicas da Chlorophyta Caulerpa cupressoides var. flabellata

Seaweeds sulfated polysaccharides have been described as having various pharmacological activities. However, nothing is known about the influence of salinity on the structure of sulfated polysaccharides from green seaweed and pharmacological activities they perform. Therefore, the main aim of this study was to evaluate the effect of salinity of seawater on yield and composition of polysaccharides-rich fractions from green seaweed Caulerpa cupressoides var. flabellata, collected in two different salinities beaches of the coast of Rio Grande do Norte, and to verify the influence of salinity on their biological activities. We extracted four sulfated polysaccharides-rich fractions from C. cupressoides collected in Camapum beach (denominated CCM F0.3; F0.5; F1.0; F2.0), which the seawater has higher salinity, and Buzios beach (denominated CCB F0.3; F0.5; F1.0; F2.0). Different from that observed for other seaweeds, the proximate composition of C. cupressoides did not change with increased salinity. Moreover, interestingly, the C. cupresoides have high amounts of protein, greater even than other edible seaweeds. There was no significant difference (p>0.05) between the yield of polysaccharide fractions of CCM and its CCB counterparts, which indicates that salinity does not interfere with the yield of polysaccharide fractions. However, there was a significant difference in the sulfate/sugar ratio of F0.3 (p<0.05) and F0.5 (p<0.01) (CCM F0.3 and CCB F0.5 was higher than those determined for their counterparts), while the sulfate/sugar ratio the F1.0 and F2.0 did not change significantly (p>0.05) with salinity. This result suggested that the observed difference in the sulfate/sugar ratio between the fractions from CCM and CCB, is not merely a function of salinity, but probably also is related to the biological function of these biopolymers in seaweed. In addition, the salinity variation between collection sites did not influence algal monosaccharide composition, eletrophoretic mobility or the infrared spectrum of polysaccharides, demonstrating that the salinity does not change the composition of sulfated polysaccharides of C. cupressoides. There were differences in antioxidant and anticoagulant fractions between CCM and CCB. CCB F0.3 (more sulfated) had higher total antioxidant capacity that CCM F0.3, since the chelating ability the CCM F0.5 was more potent than CCB F0.5 (more sulfated). These data indicate that the activities of sulfated polysaccharides from CCM and CCB depend on the spatial patterns of sulfate groups and that it is unlikely to be merely a charge density effect. C. cupressoides polysaccharides also exhibited anticoagulant activity in the intrinsic (aPTT test) and extrinsic pathway (PT test). CCB F1.0 and CCM F1.0 showed different (p<0,001) aPTT activity, although F0.3 and F0.5 showed no difference (p>0,05) between CCM and CCB, corroborating the fact that the sulfate/sugar ratio is not a determining factor for biological activity, but rather for sulfate distribution along the sugar chain. Moreover, F0.3 and F0.5 activity in aPTT test was similar to that of clexane®, anticoagulant drug. In addition, F0.5 showed PT activity. These results suggest that salinity may have created subtle differences in the structure of sulfated polysaccharides, such as the distribution of sulfate groups, which would cause differences in biological activities between the fractions of the CCM and the CCB

Avaliação ambiental de manguezais adjacentes aos campos petrolíferos de Macau e Serra (RN), como subsídio às medidas mitigadoras ao processo erosivo

Among the various effects caused by the climate change and human intervention, the mangrove ecosystem changes through of the years has been worth mentioning, which hasn t known which are the pros and cons for the adjacent coastal and estuarine environments yet. It happens due to the present dynamism in these areas, besides of the difficult understanding of the processes associated with evolution. This study aimed to environmentally evaluate adjacent mangroves from the Macau and Serra oil fields, located on Rio Grande do Norte northern coast, to support the mitigating actions related to the containment of the erosive process, as well as, according to the principles of the Clean Development Mechanism (CDM), to assess the amount of atmospheric carbon sequestered by the studied ecosystem. An inventory was conducted through mangrouve mapping which has supplied this research, especially regarding to the structural characterization of mangrove areas. To understand the local mangrove behavior in a greater level detail, techniques of remote sensing, GIS and GPS were used to make an analogy between the current and past states of the mangrove studied, allowing to make anticipated projections for the future impacts or changes in that region. This study combined data from multispectral LANDSAT 5 TM, Landsat 7 ETM+ with radar microwave data from SAR RADARSAT-1, which increased the interpretation capacity of the data from optical sensor systems. The interpretations have been supported by the data field, representing a better and innovative methodology for the environmental and taxonomic characterization of mangrove forests considered. The results reveal that mangroves of the Ponta do Tubarão Sustainable Development Reserve are biologically representative areas and providing a variety of benefits, especially for local communities, constituting the priority sites for actions development aimed at conservation. They also have been showing the necessity to make mitigating measures in order to recover degraded areas through reforestation or creating new areas of mangrove, as currently 7.1% of the mangrove forests studied are dead or in an advanced state of decomposition. The amount of atmospheric carbon sequestered proved very significant when analyzed for the whole area, which is able to sequester atmospheric 4,294,458 Ton CO2 per year

Política ambiental e desenvolvimento urbano na serra do periperi em Vitória da conquista - BA

This present dissertation has as its aim of study an analysis of the environmental policy and the urban development at the Periperi Hill. Such analysis arose due to concerns related to the disordered occupation in that Hill and also due to the environmental problems caused by this occupation. By opening roads and developing areas for housing and mineral extraction activities, man has altered considerably the landscape natural balance in that hill and caused among other difficulties, grave environmental problems, such as the erosin at the hill coast, deforestation, obstruction and pollution of the Verruga River. Therefore, in 1998 it was decreed by the Municipal Public Power that Periperi Hill became an Environmental Preservation Area with a Unit of Conservation known as Periperi Hill Municipal Park, an environmental policy implemented at the Hill that aims to hinder this occupation and to protect areas that are of great environmental importance to the city. It looking at what is now exposed and aiming to consider the Periperi Hill s environmental policy and the relationship of the occupation process, that this present work has the objective of understanding how the expansion of the city s urban network in Vitória da Conquista BA and the mineral activities cause an influence in the process of environmental degradation at the Periperi Hill

Vivendo do mar: tradição, memória e mudança na vida pesqueira de Pitangui-RN

This research focuses on the fishery activity, aligned to knowledge of past generations, and the transformation to those who depend on this activity for their livelihood, at the seashore community of Pitangui in Extremoz municipality, which lies 40 km away from Natal, seat of the state of Rio Grande do Norte. The intense modernization which has taking place during the last few years may be considered the result of a number of economic, social and cultural factors, as the introduction of new fishery technology. On the other hand, the present study seeks to show how this changing process happened, and to what extent those affected understand and evaluate this transformation. The methodology to carry out the ethnographic work was mainly adopted by qualitative methods and techniques - by participant observation, oral history, photography and the audiovisual records besides reference to data extracted under quantitative methods, as an important instrument of analyses. This induces a conclusion that the transformation of the community is a consequence of the globalized market, though still tied up to specific local relations. The emerging results are: the use of new fishery technology, and new ways of orientation and navigation; the opening to new jobs and occupational activity, the re-order of space s appropriation; changing sociability, larger access to consumer goods, besides bringing on some new conflicts land appropriation and the fishery and the protection of the environment. All this comprehended as a result of the movement of the local relations participating in the global spaces

Entre parentes :cotidiano, religiosidade e identidade na Serra de Portalegre/RN

Si les études sur les groupes noirs ruraux connaissent un essor dans l´Antropologie brésilienne contemporaine, au Nordeste, et spécialement au Rio Grande do Norte, ce genre de recherches restent rares. Ce travail a comme principal objectif de faire une description ethnographique des communautés du Pêga, do Arrojado e do Engenho Novo, dans la commune de Portalegre/RN, désignées comme des descendants africains et dont les membres se reconnaissent comme appartenant a une "grande famille". Ainsi, nous voulons analyser les processus d´élaboration d´une identité collective et comprendre le rôle des relations de parenté dans la vie cotidienne, festive et religieuse de Portalegre. En effet, nous pouvons observer que les "parents" développent des stratégies économiques et affirment leur alterité, reprennant des traits culturels et religieux qui leur sont propres pour se présenter comme un groupe doté d´une grande cohésion face a la société environnante. Nous utilisons la méthode ethnographique et la technique de l´observation participante, alliée à l´analyse des sources historiques primaires dans le but de décrire ces pratiques et stratégies. Nous pensons que la participation des membres du groupe à la production agricole, spécialement dans la confection de la farine de manioc, la construction des relations sociales au quotidien et l´organisation de la danse de São Gonçalo représentent autant d´occasions où la mémoire du groupe se fortifie, l´identité collective se cristallise et où la sociabilité se trouve consolidée. Nous analysons ces pratiques collectives et ces moments festifs comme des moyens de réaffirmation d´une identité locale centrée sur les relations de parenté
