O estudo minucioso das características físicas e químicas dos artefatos cerâmicos, associado com as pesquisas históricas e arqueológicas tem pennitido a reconstituição dos costumes culturais e modos de vida das comunidades antigas. O presente estudo objetivou estudar composição química elementar e mineralógica de cerâmicas arqueológicas coletadas nos sítios .lustino, São José, Curítuba, Saco da Onça, Porto Belo e Vitória Régia, localizados na região do Baixo São Francisco, Sergipe, Brasil. Por meio da análise por ativação com nêutrons instrumental (AANl) e difratometria de raios - X (DRX), pennitiuse definir grupos composicionais de cerâmicas conforme a similaridade química da pastas cerâmica, a qual reflete a composição da matéria-prima utilizada em sua manufatura pelo homem pré-histórico, e inferir a atmosfera e temperatura de queima da cerâmica. As amostras abeiTantes foram identificadas por meio das distâncias Mahalanobis clássica e robusta. O efeito do tempero na pasta cerâmica foi estudado por meio do filtro de Mahalanobis modificado. Os resultados foram interpretados por meio da análise de agioipamento, análise das componentes principais e análise discriminante. O horizonte temporal das cerâmicas foi verificado por meio de técnicas de datação tennoluminescência (TL). Os resultados obtidos neste trabalho, em associação com infonnações oriundas da Arqueologia, pennitiram a identificação dos gi-upos cerâmicos correspondentes às ocupações ceramistas no sítio Justino e a definição de gi\'upos cerâmicos de referência confonne o comportamento químico. A tecnologia de queima foi estabelecida para alguns vasos cerâmicos, bem como a contemporaneidade dos grupos composicionais segundo as datações determinadas por TL. Dessa forma, o trabalho contribui para a reconstituição da pré-história das comunidades que habitaram a região do Baixo Rio São Francisco e para remontagem do quadro geral das populações ceramistas do Nordeste brasileiro. / The study of the physical and chemical characteristics of the ceramics crafts, in association with historical and archaeological research, has allowed for the reconstruction of the cultural habits from ancient communities. The goal of this work was to study the chemical and mineralogical compositions of archaeological potteries collected from Justino, São José, Curituba, Saco da Onça, Porto Belo and Vitória Régia sites, located in Baixo São Francisco region, Sergipe state, Brazil. The use of the instrumental neutron activation analysis (INAA) and X-ray diffractometry (XRD), allowed the definition of compositional groups of potteries according to the chemical similarities of the ceramic paste, which reveals the composition of the raw materials utilized in the manufacturing process by prehistoric man, and the inference of the atmosphere and temperatures in which the potteries were burned. The outliers were identified by means of classic and robust Mahalanobis distance. The temper effect in the ceramic paste was studied by means of modified Mahalanobis filter. The results were interpreted by means of cluster analysis, principal components analysis and discriminant analysis. The ages of some potteries were determined by means of the thermoluminescence techniques. The results obtained in this work, in association with archaeological information, allowed for the identification of the ceramic groups relative to ceramist occupations at Justino Site and for the definition of the reference groups according to the chemical composition. The burning technology was established for some potteries and the relative ages among the compositional groups were determined by means of TL. Thus, this work provides contributions to the reconstmction of the prehistory of the communities which lived in the Baixo São Francisco region, and to the reconstitution of the general frame of the ceramist population from Brazilian Northeast.

No. of bitstreams: 0 / O modelo aplicado neste trabalho está baseado em resultados experimentais usando dados de composição química dos fragmentos cerâmicos, aplicados à teste não paramétrico de Spearmann, análise de componente principal e análise discrimante. As amostras são fragmentos cerâmicos da Tradição Tupiguarani de sítios e amostras de solos da região central do Estado do Rio Grande do Sul. Os elementos químicos, Al, Ba, Ca, Cr, Fe, K Mn, Pb, Rb, S, Si, Sr, Ti, V e Zn foram determinados usando-se as técnicas de fluorescência de raios X por dispersão de energia (EDXFR). Os elementos, Ce, Cu, Gd, La, Nd, Pr, Sm, Th e Y por espectrometria de massas de alta resolução com fonte de plasma acoplado indutivamente (HR-ICP-MS). A partir destes resultados, foram propostas relações entre as características da cerâmica, os sítios estudados e a dispersão dos fragmentos nos diversos sítios. Observaram-se indícios de assinatura química da função da vasilha de ir ou não ao fogo. A maior dispersão é de vasilhas pequenas com tratamento de superfície não corrugada. Verificaram-se assinaturas químicas para o entorno dos rios Ijuí, Ibicuí-Vacacaí Mirim e Jacuí. / Tese (Doutoramento) / IPEN/T / Instituto de Pesquisas Energeticas e Nucleares - IPEN/CNEN-SP

Este trabalho discute a incorporação de novos materiais pela escola através do estudo da leitura de impressos de RPG (role-playing games, ou jogos de interpretação de papéis). Estes impressos (livros e revistas) começaram a surgir no país por volta de 1990 e no decurso da década se diversificaram bastante, inclusive graças a uma volumosa produção de títulos nacionais. Em 2001, quando uma estudante foi assassinada em Ouro Preto e o crime foi associado à prática dos role-playing games, dois aspectos aparentemente contrários tornaramse evidentes por um lado, a presença de jogos que parodiam temas religiosos e aos quais se atribuiu influência sobre o comportamento criminoso, e por outro, a existência de livros dedicados a assuntos do currículo escolar. Com base numa aliança entre preceitos da História Cultural, da Lingüística e da Psicanálise, este trabalho procura compreender esse trajeto, pensando particularmente no problema de como surgem novos sentidos na leitura e como esses sentidos passam a ser negociados uma vez que se instauram no discurso. Através da descrição de impressos de RPG e da análise de diversos aspectos da sua leitura, manuseio e circulação, o trabalho visa discutir as formas como a linguagem não apenas manifesta, mas efetivamente sustenta e realiza as relações de poder através das quais um determinado tipo de material pode se constituir como objeto de relevância para a escola. / This work discusses the adoption of new materials in school by studying the reading of RPG (role-playing game) publications. These publications (books and magazines) first appeared in Brazil around 1990 and throughout that decade became very diverse also due to a voluminous production of national titles. By 2001, when a student was murdered in the city of Ouro Preto and the crime was reputed to role-playing game pratices, two apparently contrary aspects became evident: on the one hand, the presence of games that parody religious themes and to which an influence upon criminal behavior was attributed, and on the other hand the existence of books dedicated to school subjects. Based on concepts from Cultural History, Linguistics and Psychoanalysis, this work attempts to explain this trajectory, considering particularly the problem of how new meanings occur in reading and how these meanings are dealt with once they are installed in a discourse. By describing RPG publications and analysing how they might be read, handled and passed on among readers, this works discusses how language not only manifests, but rather supports and effects power relations by which a certain type of material may become an object of relevance from the schools perspective.

This research explored, described and explained the nature and the extent of heritage crime as it manifested in the Gauteng Province of South Africa for the period 2006-2010. Gauteng was selected since it is deemed to be the hub of the legal trade. An operational definition of heritage objects was drafted for this study as ‘objects of artistic, cultural, historic or archaeological value regardless of age, housed in or curated by museums or galleries within Gauteng, and which are both tangible and moveable.’ Heritage crime for the purpose of this study was the illegal removal of any heritage object from a museum or gallery. The annual crime statistics released by the South African Police Services (SAPS) contain no reference to heritage crime of any sort. Therefore this research attempted to quantify the incidents of thefts experienced by museums and galleries in Gauteng for the period 2006-2010. Using a mixed method approach, data were gathered by qualitative and quantitative surveys. A total of 28 qualitative interviews were conducted. These data were integrated with the quantitative data which permitted the achievement of the strategic aims set out for this research. The following aims were achieved: • The roles and responsibilities of the custodians of the national estate were clarified; • International conventions designed to assist in combating crime perpetrated against cultural property were discussed; • The national legislation which guides the management, preservation and protection of heritage objects as well as the trade therein within South Africa was examined; • Policing agencies at the forefront of combating heritage crime were interviewed and international best practices were identified and compared with that which the SAPS are doing to address crime of this nature. These police agencies are situated in Italy, the United Kingdom, the USA and Germany; • The dynamics of the reported incidents of loss/theft were examined. Several anomalies were identified. Among these are the identification of the typologies of items being targeted and the possible identification of the type of thief perpetrating these crimes. • Through analysis of incidents it was also possible to highlight that the majority of thefts occur during the time when museums and galleries are open and that the items stolen are usually on open display (not affixed to the surface and not behind a barrier of any sort). Through the analysis of the data for legal trade and the theft incidents it was possible to design a Framework depicting the interface between the legal and illegal markets for trade in heritage objects. The research also provides law enforcement with minimum guidelines to ensure that crimes of this nature are addressed more effectively. / D.Litt. et Phil. / Department of Criminology (Police Science)
