O intuito é explorar o processo de constituição da pessoa, isto é, o que se entende por ‘ser parente’ e o que se entende por ‘ser pajé’. Ao final, dialogo com os debates contemporâneos preocupados com o uso e apropriação do conceito de cultura pelos coletivos indígenas. ___________________________________________________________________________________ ABSTRACT / This thesis is an ethnographic effort on the themes of kinship and shamanism among Kurupfü, a djeoromitxí subgroup, macro-je speakers, inhabitants of the southwest Amazon (T.I. Rio Guapore/ Rondônia). Considering the connection between these two subjects of study, I approach them from the notion of perspective, because it concerns the transformation or asymmetries required by one and the other. The aim is to explore the formation process of the person, i.e., what is meant by ‘being a relative’ and what is meant by ‘being a shaman’. At the end, I’ll dialogue with contemporary debates concerned with the use and appropriation of the concept of culture by indigenous collectives.

O sítio arqueológico Furna do Estrago é um abrigo sob rocha, localizado no município do Brejo da Madre de Deus-PE, onde, de acordo com os remanescentes arqueológicos, ocorreram várias ocupações humanas pré-históricas. O estudo arqueobotânico tem como principais objetivos a identificação, a quantificação, uso e aproveitamento, além da preservação dos restos vegetais encontrados em sítios arqueológicos, buscando o conhecimento do entorno natural no suprimento das necessidades humanas na pré-história. As análises foram realizadas no material arqueobotânico (frutos e sementes) provenientes de uma área de escavação denominada Corte 7, no sítio arqueológico Furna do Estrago, onde na qual foram identificadas seis camadas estratigráficas apresentando vestígios vegetais. Os tipos de sementes foram identificados a partir de um estudo comparativo com coleções de referência pertencentes ao IPA (Empresa Pernambucana de Pesquisa Agropecuária), ao Museu Nacional do Rio de Janeiro e Jardim Botânico do Rio de Janeiro, com a participação de pesquisadores em botânica e paleobotânica no auxílio à determinação taxonômica. Dentre o material analisado, também foram observados sementes utilizados como adornos nos sepultamentos humanos em outros cortes estratigráficos, pertencentes ao sítio cemitério, apresentando colares e pingentes elaborados com vegetais, fabricados a partir de sementes, cujas datações feitas nos ossos foram de 1860±50 BP (Beta 45954) e 1610±70 BP (Beta 145955). Nos sepultamentos FE8 (indivíduo adulto, idade em torno de 30 anos, sexo masculino), FE19 (indivíduo adulto, idade 35 anos, sexo feminino) foram encontradas sementes de gindiroba (Fevillea trilobata L.) (família das Cucurbitaceae), apresentando perfurações no centro. Também observou-se a presença de sementes de pequi (Caryocar coriaceum Wittm.) (família das Cariocaraceae), as quais estavam igualmente associados ao sepultamento FE87.8 (indivíduo adulto, sexo indeterminado). Essas sementes também xi apresentavam perfurações no centro, confirmando portanto, a utilização dos macro-restos vegetais pelo homem pré-histórico na confecção de colares, provavelmente utilizados em vida, os quais constituíam parte do enxoval fúnebre dos indivíduos inumados

Transferability of community-based macro-level collision prediction models for use in road safety planning applications

Khondaker, Bidoura 11 1900 (has links)
This thesis proposes the methodology and guidelines for community-based macro-level CPM transferability to do road safety planning applications, with models developed in one spatial-temporal region being capable of used in a different spatial-temporal region. In doing this. the macro-level CPMs developed for the Greater Vancouver Regional District (GVRD) by Lovegrove and Sayed (2006, 2007) was used in a model transferability study. Using those models from GVRD and data from Central Okanagan Regional District (CORD), in the Province of British Columbia. Canada. a transferability test has been conducted that involved recalibration of the 1996 GVRD models to Kelowna, in 2003 context. The case study was carried out in three parts. First, macro-level CPMs for the City of Kelowna were developed using 2003 data following the research by GVRD CPM development and use. Next, the 1996 GVRD models were recalibrated to see whether they could yield reliable prediction of the safety estimates for Kelowna, in 2003 context. Finally, a comparison between the results of Kelowna’s own developed models and the transferred models was conducted to determine which models yielded better results. The results of the transferability study revealed that macro-level CPM transferability was possible and no more complicated than micro-level CPM transferability. To facilitate the development of reliable community-based, macro-level collision prediction models, it was recommended that CPMs be transferred rather than developed from scratch whenever and wherever communities lack sufficient data of adequate quality. Therefore, the transferability guidelines in this research, together with their application in the case studies, have been offered as a contribution towards model transferability to do road safety planning applications, with models developed in one spatial-temporal region being capable of used in a different spatial-temporal region. / Applied Science, Faculty of / Civil Engineering, Department of / Graduate

Aspects of neutron residual stress analysis

Wimpory, Robert Charles January 1999 (has links)
This thesis is concerned with the physical principles, methodology and applications of neutron diffraction in the measurement of residual stress. Work on three main areas is presented. 1) Carbon steels 2) Data and Peak Broadening analysis and 3) Single lap glue shear joints. The Carbon steels section shows the drastic effect of the content of carbon on the measured stress. This is an aspect which has been somewhat neglected in the past. The carbon is in the form of cementite, which is a hard compound and causes the carbon steel to act like a composite material, the ferrite acting as a soft matrix and the cementite as a reinforcement. The consequence of this is that the two components develop high microstresses with plastic deformation. This is clearly illustrated in the work of [Bon 97] where values of approx. 460 MPa in the residual stress in the ferrite are balanced by negative residual stresses of 2300 MPa in cementite yielding an overall macro residual stress of zero. In this work it has been shown that even knowledge of the cementite and ferrite residual stresses and fractions may not be sufficient to accurately calculate the macro stress since the ferrite unloading curve is non linear. The use of a single valued constant modulus to convert from strain to stress is hence not valid. Peak shape analysis enables dislocation density and cell size estimates to be made. The thesis examines several methods of data weighting and deconvolution in order to asses the best means of extracting this information from standard residual stress data. Care should be taken for the peaks with very low backgrounds when finding the Gaussian and Lorentzian components. A weighting that avoids the strong bias of zero and I counts in the detector channels should be used e.g. W = I / ( 10 + Y). Lorentzian and Gaussian components can be successfully extracted from asymmetrical peaks (of peaks that broaden symmetrically), using deconvolution method 1, although the data should be of good quality. Reproducibility has been shown in the Gaussian, Lorentzian and FWHM for different instruments at different institutes. This is extremely important for the use of these values for peak broadening analysis and for estimation of the plastic deformation within a sample. The neutron diffraction technique has been used to investigate the longitudinal stresses in the adherend produced as a result of cure and due to the application of a tensile load in a single lap shear joint. The results throw doubt on widely used finite element predictions.

Macro-econometric modelling for the Nigerian economy : a growth-poverty gap analysis

Akanbi, Olusegun Ayodele 25 September 2010 (has links)
This study develops comprehensive full-sector macro-econometric models for the Nigerian economy with the aim of explaining and providing a long-term solution for the persistent growth-poverty divergence experienced by the country. The models are applied to testing the hypothesis of existing structural supply-side constraints versus demand-side constraints impeding the growth and development of the country. Structural inadequacies have been the major setback to the achievement of the developmental objectives in the Nigerian economy. The last four decades has revealed several macroeconomic instabilities that hinder much improvement in the performance of the economy. Much of these structural inadequacies have been blamed on the persistent poor governance experienced by the country over the years. The poor political leadership and instability, corruption and the mismanagement of the oil resources have halted an appropriate and sound economic policy that should have alleviated poverty among the majority of the population. A review of the historical performance of the Nigerian economy reveals significant socio-economic constraints as the predominant impediments to high and sticky levels of poverty in the economy. As such, a model of the Nigerian economy suitable for policy analysis needs to capture the long-run supply-side characteristics of the economy. A price block is incorporated to specify the price adjustment between the production or supply-side sector and real aggregate demand sector. The institutional characteristics with associated policy behaviour are incorporated through a public and monetary sector, whereas the interaction with the rest of the world is presented by a foreign sector, with specific attention given to the oil sector. The models are estimated with time-series data from 1970 to 2006 using the Engle-Granger two-step cointegration technique, capturing both the long-run and short-run dynamic properties of the economy. The full-sector models are subjected to a series of policy scenarios to evaluate the various options for government. It is evident from the policy options assessed in this study that there is a need for an improvement in the quality of government spending. Fiscal policy expansion should tend towards increasing the component of government expenditure that will lead to sustained growth and also an improvement in the standard of living of the citizens. In order to be able to reap the benefits of a positive external shock, there is a need to increase the level of competitiveness and the productive capacity of the country. Investment in basic infrastructure such as power and roads is very crucial at this stage of the Nigerian economy. There is an urgent need to refocus the government role in certain critical areas of the economy. Government institutions need to be strengthened by improving the coordination that exists within the government structures. The political environment needs to be more secure in order to attract more private investment. The maintenance of public order, ensuring property rights, a sound regulatory structure and also creating a framework that will increase the provision of public goods and services and the maintenance of infrastructure are urgent elements required in order to achieve the set macroeconomic objectives. / Thesis (PhD)--University of Pretoria, 2010. / Economics / unrestricted
