L'objectiu d'aquesta tesi doctoral és l'edició i l'estudi de la Vida de la sacratíssima verge Maria (València, Nicolau Spindeler, 1494) de Miquel Peres, una de les obres produïdes en el segle d'or valencià i que a hores d'ara encara no compta amb cap edició moderna ni amb estudis que li hagen dedicat una atenció especial. És l'obra més original de les conservades de l'autor, i també la que gaudí d'una major acollida, ja que es reedità diverses vegades tant en el segle XV com en el XVI especialment, i tant en la tradició catalana com en la castellana. Probablement la bona recepció que tingué està directament relacionada amb el context espiritual imperant en l'albada de l'edat moderna, una espiritualitat renovada i de caire intimista que troba en la contemplació devota una de les principals vies d'expressió, i que veiem exemplificada en les pàgines d'aquest volum. Tanmateix, no compten amb cap treball que s'haja ocupat d'editar el text ni d'analitzar-ne la gènesi o la difusió notable de què va gaudir, ja que la producció d'aquest autor ha estat força desatesa. La hipòtesi que motiva aquest treball parteix de la consideració que en els estudis de literatura catalana Miquel Peres no ha estat considerat fins ara com un escriptor de primera línia, i, tanmateix, tant el volum de la seua producció, com les característiques concretes de les seues obres, fan pensar que mereix una reconsideració i un estudi detingut per poder plantejar una revalorització dels seus texts. A través d'aquest treball mirarem de situar la Vida de la sacratíssima verge Maria en el panorama literari i espiritual peninsular, de manera que es pose de manifest l'originalitat que suposà, i que explica l'èxit que se'n seguí, i contribuirem al coneixement de l'activitat literària de la València lletraferida de les darreries de l'edat mitjana i els inicis de l'edat moderna.

Subduction zones are places where one hydrated oceanic plate goes underneath another plate, and releases its fluids into the overlying mantle wedge. Slab-derived fluids play a key role in subduction zone processes. They serpentinize the cold forearc mantle at shallow depths; and deeper, they trigger hydrous mantle melting beneath the arc volcanoes and sometimes at backarc basin (BAB) spreading center. Examining the composition of arc and BAB magmas helps understanding genesis of subduction-related magmas, nature and composition of their mantle sources and slab-derived fluids. However, investigating such processes at shallow subduction zones is challenging, because the cold forearc mantle generally does not melt. Here, I investigate an unusual region in the southernmost Mariana convergent margin in the Western Pacific, near the Challenger Deep. The SE Mariana forearc stretched to accommodate opening of the southernmost Mariana Trough ~5Ma ago, opening the SE Mariana forearc rift (SEMFR) and causing seafloor spreading ~2.7-3.7Ma ago. The subducted slab beneath SEMFR deepens from <50km to ~100km, thus studying SEMFR lavas provides a unique opportunity to understand shallow subduction processes. By examining the major and trace element composition, the Pb-Nd-Sr isotopic ratios and the volatile contents (H2O, CO2, Cl, S, F) of SEMFR basalts, associated glassy rinds and olivine-hosted melt inclusions (Ol-MI) collected during three cruises (YK08-08, YK10-12, TN273), I show that: (i) SEMFR lavas were produced by adiabatic decompression melting of depleted asthenospheric BAB-like mantle at ~30±6.6 km depth and 1224±40oC; (ii) Ol-MI represent hydrous melts trapped by forearc mantle olivines. Xenocrysts were entrained with SEMFR basalts during ascent; (iii) SEMFR mantle flowed from the forearc towards the arc volcanoes and was metasomatized by shallow aqueous fluids; (iv) SEMFR shallow fluids are more aqueous than the fluids released beneath the Mariana arc and Mariana BAB; (v) the aqueous slab-derived fluids and the volatile fluxes are greatest at ~50-100km slab depth, suggesting that the minerals from the subducting plate mostly broke down beneath the arc to release their fluids. Such results provide new insights into shallow subduction processes, as previous studies showed that volatile fluxes and aqueous slab-derived fluids should increase toward the trench.

A população é predominantemente negra com 530 habitantes que vivem da agricultura de subsistência e da criação de pequenos animais (cabras, porcos, galinhas, capotes). O enfoque do presente trabalho é a religiosidade. No Mimbó existe a prática de uma Devoção Mariana com o culto a Nossa Senhora da Saúde, padroeira local, festejada no mês de agosto desde o começo do século XX. E um terreiro onde os mimboenses praticam a Encantaria (religião afro-brasileira do Amazonas, Pará, Maranhão e Piauí onde as entidades espirituais são denominadas encantados e organizam-se em famílias espirituais). O terreiro foi dedicado a Barba Soeira (entidade espiritual sincretizada com Santa Bárbara e Iansã) e fundado por Augusto Rabelo da Paixão na década de 1970, depois de desenvolver a crôa/cabeça (a mediunidade) no terreiro do mestre Zé Bruno, famoso chefe de terreiro e curador do povoado Nazaré no interior do município de Caxias, Maranhão. Os iniciados ou médiuns do terreiro do quilombo Mimbó se definem como “cavalos” das entidades espirituais, onde predomina a Encantaria de Barba Soeira chefiada pela entidade espiritual conhecida como “Légua-Boji-Buá” chefe da “Linha da Mata do Codó” ou Tambor da Mata. / Localized in rural zone, in medium Parnaíba area, Amarante, Piauí, Brasil, the Mimbó quilombo, was originated about a century ago, by fled slaves of actual district of Oeiras; next rivers Canindé, and Mimbó rivulet. The population is predominantly black with 530 habitants, who live of subsistence agriculture and goats, pigs and chickens raising.. The present work focus is on religiosity. There is in Mimbó a small church for devotion to Our Lady of Healthof - the local pactron – which is worshipped in August, priod of the feasts in her homage, a terreiro where mimboenses practice the Encantaria (Enchant cult), another afro-brasilian religion of Amazonas, Pará, Maranhão and Piauí, whose spiritual entites are organized in families. The Barba Soeira terreiro is dedicated and was founded by Augusto Rabelo da Paixão in the decade of 1970, when he had developed mediunity in master Zé Bruno`s terreiro, a famous wizard and medicine man from Nazaré in the Caxias, Maranhão. The initiates are defined as “horses” of the spirituals entites. In Encantaria de Barba Soeira (Enchant cult) prevails the family of the spiritual entity known as “Légua-Boji-Buá” , leader of Forest Line of the Codó, Maranhão.

Orientador: Márcia Regina Capelari Naxara / Resumo: Este trabalho tem como objeto de análise os oficiais da Guarda Nacional no atual Estado de Minas Gerais, em especial na cidade de Mariana. A Guarda Nacional foi uma milícia criada pelos liberais durante a Regência e participou ativamente da vida institucional do Brasil no processo de formação do Estado Nacional no oitocentos. Neste sentido, pretendemos evidenciar o sistema eletivo para o oficialato da milícia cívica como um mecanismo de teste do prestígio social dos oficiais civis, no período entre 1831 e 1850, numa tentativa de esmiuçar o microcosmo social dos indivíduos arregimentados no afã do espírito de associação territorial do Império e de legitimidade do Estado / Abstract: This paper broaches the National Guard's officers in the present State of Minas Gerais in the special city of Mariana. The National Guard was a militia created by liberals during the Regency and participated actively in the institutional life of Brazil in the National State's formation process in eighteen hundred. So, this paper intends to show the officers's election of civic militia as a test mechanism of officers's social prestige, in the period between 1831 and 1850, trying to research about the social microcosmos of individuals enlisted in association spirit of Empire territory and State's legitimacy / Mestre

Neste sentido, o nosso principal objetivo com esta pesquisa é problematizar e examinar a participação do jornalismo na configuração e na expressão da experiência rural contemporânea, presente nos contextos imediatamente afetados pelo rompimento das barragens de Fundão e Santarém. A partir de tal objetivo, a pesquisa se desenvolveu visando investigar a relação entre jornalismo, acontecimento, temporalidades e vida social. Posteriormente, examinamos as expressões e as configurações dos modos de vida rurais no jornal A Sirene, problematizadas pela tragédia exposta publicamente. Por fim, investigamos as configurações da relação entre mineração, mineiridade e ruralidade presentes no jornal citado. De modo mais específico, procuramos com esta pesquisa, demonstrar como o sofrimento provocado pela tragédia, e mostrado pelo jornalismo, foi capaz de evidenciar nuances e traços dos contextos rurais afetados pela tragédia, em meio a uma contemporaneidade marcada por significativas transformações nos cenários rurais. Para isso, partimos de uma pesquisa bibliográfica acerca da temática proposta e assim, analisamos as 12 primeiras edições do jornal A Sirene a partir da abordagem de paisagens textuais e análise de conteúdo verbo-visual. De uma forma geral, percebemos que o jornalismo se mostrou como um modo de experimentar a vida social e de atualizar o presente e ainda, uma forma de explicitar, a partir de narrativas, o sofrimento e o modo de vida dos sujeitos das regiões afetadas. Por fim, notamos que estamos falando de sujeitos híbridos e que, este hibridismo emerge com uma série de problemas em contextos globalizados, pois são nestes contextos que há a construção de periferias que não são vistas frente às sociedades hegemônicas. / This dissertation arose from the investigation of the relationship between journalism and the production of meanings in rural areas in the context of the Mariana Tragedy (2015), more specifically in the community of Bento Rodrigues and other affected localities. In this sense, our main objective with this research is to problematize and examine the participation of journalism in the configuration and expression of the contemporary rural experience, present in the contexts immediately affected by the rupture of the dam of Fundão and Santarém. From this objective , the research developed to investigate the relationship between journalism, events, temporalities and social life. Later, we examined the expressions and configurations of the rural ways of life in the newspaper A Sirene problematized by the publicly exposed tragedy. Finally, we investigate the configurations of the relationship between rurality, mining and mineiridade present in the cited newspaper. More specifically, we seek to demonstrate how the suffering provoked by tragedy, and shown by journalism, was able to show nuances and traces of the rural contexts affected by the tragedy, in the midst of a contemporaneity marked by significant transformations in rural settings. For this, we start with a bibliographical research about the proposed theme and thus, we analyzed the first 12 editions of the newspaper A Sirene from the approach of textual landscapes and analysis of verb-visual content. In a general way, we perceive that journalism has been shown as a way of experiencing social life and of updating the present, and also, a way of explaining, from narratives, the suffering and way of life of the subjects of the affected regions. Finally, we note that we are talking about hybrid subjects and that, this hybridism emerges with a series of problems in globalized contexts, because it is in these contexts that there is the construction of peripheries that are not seen in front of hegemonic societies.

La principal razón que ha motivado esta investigación, es el estudio de la fotografía como soporte y lenguaje, ya sea de expresión o de información. Para esto se ha revisado la obra fotográfica de Mariana Matthews y ésta se ha trasladado desde el campo del arte al campo del patrimonio, concentrando el interés no sólo en la fotografía que se considera como patrimonio a raíz de la valoración que se le da a través del tiempo, dada su significación histórica; sino también en aquella que podría ser valorada como patrimonio desde su origen, desde el momento en que el artista encuadra y aprieta el obturador.

Fluid-mobile elements (FMEs) such as B, Cs, As, Li and Tl can mobilize readily under low P-T conditions (0.2-0.5 GPa). This makes them effective geochemical tracers that can be used as a way of tracking fluid-rock exchanges at the shallow depths encountered in the earliest stages of subduction. The Izu-Bonin-Mariana (IBM) subduction system is unique in that it preserves a record of the sequences produced from the onset of subduction through the development of arc magmatism. International Ocean Discovery Program (IODP) Expedition 352 recovered >800m of boninite core material from the earliest IBM magmatic events. Select boninitic glasses from these IODP 352 cores, found mostly as selvages on the rinds of pillow lavas and as clasts within hyaloclastites, were examined via EPMA and laser ablation ICP-MS techniques. The boninite glasses analyzed were separated into two categories – low-silica boninite (LSB) and high-silica boninites (HSB), based on the bulk chemistry and mineralogy of the lithostratigraphic locations from which the glass samples occur in the drill core. LSB are the earlier erupted boninite series, which show both greater variation in extent of differentiation and reflect less depleted mantle sources than HSB. Boron concentrations in the Expedition 352 boninite glasses analyzed range from 0.08 to 12.91 ppm, arsenic contents vary from 0.15 to 3.26 ppm, and cesium varies from 0.01 to 0.91 ppm. Lithium concentrations in the boninites range from 1 to 18.35 ppm while Tl concentrations vary from 10 to 155 ppb. FME concentrations trend toward higher values in HSB than in LSB. Low-Si boninites appear to form via simple mixing of depleted mantle source and an FME enriched fluid endmember, which mobilizes B, As, Cs, (Tl) and Li very early in the subduction process. Coupled with inputs from upwelling mantle, this FME-rich fluid triggers fluid-fluxed boninite melting. The high-Si boninites reflect the addition of a subduction component with a higher Ba/La ratio than that of the depleted mantle; this higher ratio more closely resembles that of Mariana cherts from altered Pacific crust. Thus, the high-Si boninites are consistent with the fluid-fluxed melting of a highly depleted, harzburgitic mantle source and reflect inputs of two distinguishable slab-derived components, one that is sedimentary in nature and another that is FME-enriched. This model for melting that is more similar to the melting regime of modern arcs and reflects the transition from early extension-related melting into that of a “normal” subduction system.
