In the work of the author in question ? as well as in the work of many others crime fiction writers ?, we show clearly that the representation of the criminal universe is a method or a means of making the reader reflect on things more widely than the simple ?who killed? questioning. We aim to demystify the ideia very widespread among literary critics that crime fiction is a ?minor genre?. In this regard, we discuss the characteristics, similarities and differences between its types: detective fiction, noir and ?action? fiction. This last type, although practiced by writers like Edgar Allan Poe e Jorge Luis Borges, for example, had its terminology coined only in 2005, by Mayrant Gallo, who is also a teacher and a crime fiction theorist, a genre which has been insufficiently researched in the academy. / Neste trabalho, analisamos os contos policiais do escritor Mayrant Gallo ? um dos mais fecundos autores da Bahia na contemporaneidade ? tentando demonstrar a tem?tica do crime como uma met?fora, uma meton?mia do mundo em que vivemos, muitas vezes violento e corrupto. Na obra do autor em foco ? assim como na de tantos outros escritores de hist?rias policiais ? evidenciamos a representa??o do universo criminal como um m?todo, um meio de levar o leitor a reflex?es bem mais amplas do que ao mero questionamento do ?quem matou?. Objetivamos desmitificar a ideia, que ainda perdura entre os cr?ticos liter?rios, de que a narrativa policial ? um ?g?nero menor?. Para tanto, discutimos as caracter?sticas, semelhan?as e diferen?as dos tipos da modalidade estudada: de enigma, noir e ?de a??o?. Este ?ltimo, apesar de ter sido praticado por escritores como Edgar Allan Poe e Jorge Luis Borges, por exemplo, teve a sua terminologia cunhada apenas em 2005, por Mayrant Gallo, que, al?m de escritor, ? professor e te?rico da literatura policial, pouco divulgada no ?mbito universit?rio.

As discussões sobre identidades e representações em museus estão em voga desde a década de 1960, quando se objetivava sanar a ausência de comprometimento social das instituições. Na década de 1970, chegava à Ilha de Marajó o padre jesuíta italiano Giovanni Gallo que, com o intuito de desenvolver a região, viu na criação de um museu que representasse a identidade cultural do caboclo marajoara um meio possível de alcançar esse objetivo. Mesmo com as dificuldades de construir um museu em uma região carente de diversas estruturas, O Museu do Marajó foi fundado em parceria com a comunidade e apresentou, já naquela época, o diferencial de uma exposição interativa analógica. Neste contexto é que esta pesquisa busca contribuir para a análise da representação das identidades nos museus concentradas em ferramentas interativas, tendo como estudo de caso O Museu do Marajó. Para isso, foi realizada uma análise da exposição de longa duração do Museu e de como ela foi construída ao longo da história da instituição. / Discussions of identities and representations in museums are in vogue since the 1960s, when it aimed to remedy the lack of social commitment of institutions. In the 1970s, he came to the Marajo Island Italian Jesuit priest Giovanni Gallo that, in order to develop the region, saw the creation of a museum that represented the cultural identity of the Caboclo marajoara a possible means of achieving this goal. Even with the difficulties of building a museum in a poor region of several structures, O Museu do Marajó was founded in partnership with the community and presented, even then, the differential analogical interactive exhibition. In this context, this research aims to contribute to the analysis of the representation of identities in museums focused on interactive tools, with the case study The Marajó Museum. For this, we performed an analysis of exhibition and how it was built along the history of the institution.

L'objectif de cette thèse est de combler des lacunes scientifiques dans la connaissance de l’histoire du francoprovençal et de son lexique. En effet, à l'heure actuelle aucun travail de synthèse ne regroupe les matériaux anciens du francoprovençal et dans le Französisches Etymologisches Wörterbuch (FEW), qui pourrait remplir cette fonction, les états anciens du francoprovençal sont sous-représentés en raison de l'absence d'un tel travail. La conséquence est un grand déséquilibre avec la connaissance que nous avons de l'ancien français et occitan qui sont les langues romanes anciennes les mieux décrites. Les sources en francoprovençal sont relativement peu nombreuses parce que cette langue a été de tout temps confiné à un usage essentiellement oral. La littérature ancienne se borne à quelques textes d'édification et un traité juridique, surtout des traductions. À partir du XVIième siècle se développe une littérature en patois le plus souvent fortement ancrée localement. Les auteurs qui voulaient toucher un publique plus large ont très tôt opté pour le français. Les sources documentaires sont plus nombreuses, mais très inégalement réparties dans l'espace. Les sources issues de la partie française du domaine ont pour la plupart été éditées, mais beaucoup d'entre elles sont difficilement exploitables en l'absence de glossaires. La situation est plus favorable en Suisse romande où le Glossaire des patois de la Suisse romande (Gl.) documente non seulement les dialectes modernes, mais aussi leurs états anciens. Pour cette raison nous nous sommes concentrée sur la partie française du domaine et nous nous sommes basée sur le Gl. pour la partie suisse. En collaboration avec une autre doctorante, Laure Grüner, nous avons rassemblé les sources intéressantes pour l'étude de l'ancien francoprovençal de France et nous avons procédé à des dépouillements étendus. Sur cette base, nous avons élaboré un modèle de description lexicographique adapté à l’ancien francoprovençal et nous avons rédigé la tranche f de ce Dictionnaire de l'ancien francoprovençal, qui représente environ un vingtième du dictionnaire complet, afin de prouver la faisabilité du projet et d'évaluer son apport à la connaissance de l’ancien francoprovençal. Plus de la moitié de nos articles documentent des unités lexicales qui n'étaient pas encore attestées en ancien francoprovençal de France dans le FEW et dans une bonne partie des autres cas nous pouvons compléter les matériaux. Sur la base des 386 articles rédigés, nous évaluons la nomenclature complète du dictionnaires à 7’500 articles et le temps de rédaction à une bonne douzaine d'années de travail d'une personne à temps plein. Nous avons aussi envisagé plusieurs possibilités pour obtenir des résultats tangibles dans des délais plus courts / The aim of this thesis is to fill in the scientific gaps concerning the knowledge of the history of Francoprovençal and its vocabulary. Currently, there is no synthesis of the available documentation of Old Francoprovençal. In the Französisches Etymologisches Wörterbuch (FEW), that could fulfil this function, the older states of Francoprovençal are underrepresented because of the lack of this kind of work. The consequence is a huge imbalance with the knowledge we have for instance of Old French and Occitan which are the best known Romance languages of the past.There are few sources in Francoprovençal because this language has always been mostly oral. The oldest literature consists of a few religious texts and a legal treaty. Most of them are translations. From the 16th century onward, a locally based literature emerges generally with modest ambitions. Authors wanting to reach a larger audience chose French at a very early stage. The documentary sources are more numerous but very unevenly spread. Most sources from the French part are edited, but many of them lack a glossary and are difficult to handle. The situation is better in Switzerland, where the Glossaire des patois de la Suisse romande (Gl.) provides documentation not only regarding the modern dialects but also their older stages. For this reason, we concentrated our work on the French part and relied on the Gl. for the Swiss part. Together with an other PhD student, Laure Grüner, we gathered the sources and extracted the interesting lexical forms.Based on this documentation, we elaborated a lexicographical description template suitable for Old Francoprovençal. We wrote the articles of this Dictionnaire de l'ancien francoprovençal beginning with the letter f which represents about one twentieth of the whole dictionary. Not only did this provide a proof of its feasibility, but it also assessed its contribution to the knowledge on Old Francoprovençal. More than a half of the articles gather evidence for lexical units not yet documented in this language regarding the French part of the linguistic area, whereas for most of the others we could complete the existing documentation. Based on the 386 articles written, we estimate the complete nomenclature at approximately 7’500 articles and the time needed to write them at about twelve years. We also considered various possibilities to get tangible outcomes in a shorter amount of time

L'objectif de nos recherches est de caractériser les pratiques funéraires et plus généralement les comportements des populations vivantes vis-à-vis des morts : traitement et dépôt du corps, mobilier funéraire, architecture funéraire mais également gestion des espaces funéraires, topographie et dynamique de l'occupation funéraire. <br />Pour cela, nous avons établi un corpus répertoriant plus de 400 sites. Intégré à un SIG, il nous a permis d'observer la répartition des gisements funéraires sur le territoire. Les deux points les plus remarquables sont la différence d'implantation entre les sites funéraires et ceux d'habitats et le hiatus existant entre les nécropoles du Haut-Empire et celles de l'Antiquité tardive. <br />Après avoir sélectionné cinq sites, nous avons entrepris une analyse de plus de 1200 sépultures en associant données archéologiques et anthropologiques pour apporter de nouveaux éléments de réflexions à la compréhension des pratiques funéraires gallo-romaines. Dans le cas des sépultures à incinération, nous nous sommes plus particulièrement intéressé aux gestes de collecte et de stockage des restes du défunt. Pour les inhumations, nous avons surtout porté notre attention sur les apports des données biologiques à la définition des regroupements familiaux ou sociaux. <br />L'ensemble de ces données souligne l'existence de faciès locaux au sein de la cité et met en évidence l'importance du contexte archéologique dans lequel s'inscrit la nécropole pour la caractérisation des gestes funéraires.

First, we present a detailed discussion about handling data, we show the impossibility of using the mid-price quote due to the high number of buy / sell orders that present very high / low prices. We checked some of the empirical stylized facts pointed out by Cont (2001), among others enshrined in the microstructure literature. In general, the stylized facts were replicated by the data. We apply the filter, proposed by Brownlees and Gallo (2006), to Petrobras' stock and we analyze the sensitivity of the number of possible outliers found by the filter with respect to the filter's parameters variation. We propose using the Akaike criterion to sort and select conditional duration models whose samples have different length sizes. The selected models are not always those in which the data has been filtered. For the ACD (1,1) setting, when we consider only well-adjusted models, the Akaike criterion indicates as better model as one in which the data were not filtered. / O presente trabalho utiliza os dados disponibilizados pela BM&FBovespa para analisar as ações da Petrobrás para os meses compreendidos entre julho e agosto de 2010 e outubro de 2008. Primeiramente, apresentamos uma discussão detalhada sobre a manipulação desses dados, na qual explicitamos a impossibilidade de se usar o mid-price quote devido ao número elevado de ofertas de compra/venda com preços muito elevados/baixos. Verificamos alguns dos fatos estilizados empíricos apontados por Cont (2001), entre outros consagrados na literatura de microestrutura. Em geral, os dados replicaram os fatos estilizados. Aplicamos o filtro proposto por Brownlees e Gallo (2006) às ações da Petrobrás e analisamos a sensibilidade do número de possíveis outliers encontrados pelo filtro a variação dos parâmetros desse filtro. Propomos utilizar o critério de Akaike para ordenar e selecionar modelos de duração condicional cujas amostras de duração possuem tamanhos distintos. Os modelos selecionados, nem sempre são aqueles em que os dados foram filtrados. Para o ajuste ACD (1,1), quando considerados apenas os modelos bem ajustados (resíduos não autocorrelacionados), o critério de Akaike indica como melhor modelo aquele em que os dados não foram filtrados.

La monumentalisation de l’architecture figure parmi les marqueurs les plus éloquents de la pénétration de la culture romaine en Gaule, après la conquête. Peu de temps après l’instauration du Principat, de nouveaux édifices couverts de sculpture ornementale viennent en effet bouleverser le paysage architectural désormais gallo-romain. Sans précédent dans les constructions laténiennes, les décors architectoniques connaissent dès lors une importante diffusion et évoluent au gré d’influences diverses dont les premières sont dictées par des jalons métropolitains comme le temple de Mars Ultor.Plusieurs auteurs ont déjà proposé des synthèses retraçant l’évolution des décors architecturaux de Rome à l’époque impériale, pour le Ier siècle notamment. Elles sont en revanche beaucoup plus rares dès lors que l’on s’intéresse aux provinces de l’Empire et en particulier au nord des Gaules et aux Germanies, alors même que le matériel y est abondant. Ce constat est d’autant plus vrai à mesure que l’on avance vers la dynastie des Antonins puis vers les Sévères, à tel point que la seconde moitié du IIe et le IIIe siècles sont des époques quasiment désertées par les chercheurs.Situé dans la lignée de travaux récents concernant le décor architectonique « tardif » en Gaule et dans les Germanies (Genainville, Champlieu, Neumagen, Bordeaux, Pont-sainte-Maxence), ce travail propose une nouvelle synthèse centrée sur les deux derniers tiers du IIe et le IIIe siècle de notre ère. À partir d’un corpus réuni au sein des territoires éduen, lingon et sénon, il tente d’une part de caractériser les décors employés sur les bases, colonnes, chapiteaux, architraves, frises et corniches. En mettant en lumière une évolution pour chacun de ces éléments, il est alors possible de dégager des éléments chrono-typologiques. La question du répertoire ornemental est également abordée, ce qui permet de s’interroger sur les mécanismes évolutifs, la circulation des modèles et les différentes contraintes qui président aux changements observés. Enfin, l’étude des blocs permet de proposer plusieurs restitutions et d’ainsi avoir une idée de l’activité architecturale qui caractérise les différents sites observés. / The development of monumental stone architecture was part of the most telling clues about roman culture entering in Gaul, after Cesar’s conquest. Short while after the Principate started, new buildings covered with ornamental sculpture created a new architectural landscape in the territories that thus formed the roman Gauls. Even though architectonic ornaments had no precedent in the Iron Age, their spread quickly became very important. Ornaments thus started to evolve, taking monuments from Rome itself as first models ; for example the temple of Mars Ultor.Several authors have already written papers about the evolution of architectonic ornaments in the Imperial Rome, in particular for the Ist century AD. However, publications about the Provinces of the Empire are scarcer, especially regarding north of Gauls and Germanies. This observation is even more obvious for later periods such as the second half of the IInd and the IIIrd century A.D.My thesis belongs to a serie of recent works about « late » architectonic ornaments in roman Gauls and Germanies (about collections such as those of Genainville, Champlieu, Neumagen, Bordeaux, Pont-sainte-Maxence). It focus on a period from the years 130 to the years 230 AD (approximately from the reign of Antoninus to this of Alexander Severus). From a corpus gathered over three civitates (Aedui, Lingones, Senones), my work tries to define which ornaments were employed on the components of architectural orders (basis, columns, capitals, architrave, friezes, cornices), to understand how they were allocated, and to highlight how they evolved over decades. Ornamental repertory is also an important point : it allows to question about evolution mechanisms, patterns diffusion and other reasons that made handcrafters change their carving techniques. To finish, studying architectonic pieces provide possibilities of reconstructing monuments, so as to have a idea of what was building activity like in the three studied civitates.

La présence de la sigillée gauloise en Transpadanie occidentale est connue de longue date par les chercheurs locaux, mais cela reste peu connu à la fois aux niveaux national italien et international. On en ignore surtout la portée. Un pourcentage de sigillée gauloise très important découverte dans chantiers de fouille immédiatement à l’intérieur de l’enceinte romaine de Turin, a modifié cette perspective. Il est apparu que les sigillées gauloises ne pouvaient plus être considérées comme une présence sporadique, ni comme le résultat de réapprovisionnements destinés exclusivement aux classes les plus aisées, mais constituaient un indicateur économique important. De cette constatation est née la nécessité de reprendre l’examen des attestations de sigillées gauloises en Transpadanie occidentale dans leur ensemble, y compris par comparaison avec la situation d’autres réalités de l’Italie du Nord, avec l’objectif d’établir non seulement la provenance du vaisselle, mais aussi des routes commerciales empruntées. La voie principale d’approvisionnement de toute la Cisalpine a été le Pô. Huile, vin et garum, atteignent les marchés transpadanes et de la Ligurie interne par voie fluviale, partant des côtes adriatiques et orientales et aussi depuis la péninsule ibérique. Le choix d’utiliser la diffusion des sigillées de la Gaule centrale en tant que fossile directeur pour reconstituer l’existence d’une voie de circulation commerciale en Cisalpine d’ouest en est naît de l’idée que l’on est en présence de produits qui ne disposent plus d’un réseau de distribution méditerranéen, alors qu’ils se concentrent en revanche en Europe continentale et en Bretagne. / The presence of the Gaulish Terra Sigillata in Transpadana has been well known for a very long time by local researchers, but on an Italian national and an international level, it is hardly known. Most importantly, its extent has been ignored. A very important amount of Gaulish Terra Sigillata, discovered on an excavation site immediately close to the city wall, inside and outside the Roman settlement of Turin, radically modified this idea. It has very quickly become apparent that the Gaulish Terra Sigillata cannot be considered as a random find any more, nor the result of supplying intended exclusively to the upper classes, but constituting a rather important economic indicator. From this observation, the need to re-examine the evidence of Gaulish Terra Sigillata in western Cisalpine is clear, including the need to compare the situation with others in northern Italy, with the aim to establish, not only the provenance of the crockery, but also, above all, the trade route that was used. The main trade route in the whole of Cisalpine Gaul was the river Po. Oil, wine and garum reached the markets of Transpadana and internal Liguria by waterway from the Adriatic and eastern coasts and, probably also, from the Iberian Peninsula. The decision to use the Terra Sigillata of central Gaul as a type fossil to reconstruct a circulation route from the west to the east of Cisalpine, with more or less distant provenances, was based on the consideration that these products didn’t use the Mediterranean distribution network any more, but actually they concentrated on continental Europe and Brittany.

Notre thèse comporte l’étude du mobilier céramique provenant des fouilles hongroises de l’Îlot des Grandes Forges à l’oppidum gaulois de Bibracte (Le Mont Beuvray, Bourgogne). Le but de notre travail était non seulement de traiter et de publier le mobilier céramique provenant des différents états d’occupation de l’Îlot des Grandes Forges, mais aussi de compléter les études céramologiques qui s’occupent de l’oppidum de Bibracte. Nous proposons une chronologie bien établie pour l’Îlot des Grandes Forges, chantier d’importance remarquable qui a livré l’une des constructions les plus étonnantes du site: la basilique de Bibracte. Et finalement, le travail constitue une contribution à la compréhension plus approfondie de la chronologie de l’oppidum, ainsi qu’à la définition des faciès céramologiques de Bibracte. / My PhD dissertation contains the detailed study of the pottery finds from the Hungarian excavations of the « Grandes Forges » insula. The insula is located in the oppidum of Bibracte (Le Mont Beuvray, Burgundy). The primary aim of this work is not only to study and to publish the pottery finds of the different occupation layers but also to contribute to the results of the already existing ceramic studies of the oppidum of Bibracte. My work offers a chronology to the « Grandes Forges » insula, an archeological site of great importance where the remains of the roman basilica of Bibracte have been found. Finally my work tries to give a better understanding of the chronology and provides a survey of the pottery finds of the oppidum of Bibracte.

The San Pedro del Gallo area 1.8 in the north-central part of Mexico, between 25°30' and 26°00' N latitude, and 104°00' and 104°20' W longitude. It covers approximately 1,900 square kilometers at the western edge of the Sierra Madre Oriental. The oldest rocks exposed in the area belong to the Villa Juarez Formation of possible Late Triassic age. These rocks, of continental origin, comprise siltstone, sandstone, conglomerate, tuff, and intercalated lavas of characteristic red color. Jurassic and Cretaceous rocks form a section with a maximum thickness of about 3,580 m. The sediments were deposited in the Mexican Geosyncline, west of the Coahuila Peninsula of pre-Aptian age. The Villa Juarez Formation is overlain with angular unconformity by orthoquartzite, quartzose sandstone, and limestone lenses of the La Gloria Formation of Oxfordian age. The La Casita Formation, which is stratigraphically above the La Gloria Formation, probably ranges in age from late Oxfordian to early Neocomian. It consists of thin-bedded limestone, black shale, and varicolored sandstone, with intercalations of coal seams and abundant ammonites. The Lower Cretaceous rocks of the area comprise the Coahuila Series, La Pena Formation, Aurora Limestone, and Cuesta del Cura Formation. Neocomian and upper Aptian rocks are represented by thin-bedded limestone, marl, and shale of the Taraises, Las Vigas, Parritas, and La Pena Formations. This sequence of rocks is overlain with apparent conformity by the medium- to thick-bedded bank-type Aurora Limestone of middle to late Albian age. A notable change of facies occurs laterally in the upper Albian and lower Cenomanian rocks, the lithology of the Aurora Limestone grading westward into the thin-bedded limestone with wavy bedding planes and black chert intercalations that characterize the Cuesta del Cura Formation. An erosional unconformity developed on the surface of the Aurora Limestone and Cuesta del Cura Formation is covered by the Indidura and Caracol Formations of Turonian to Coniacian age. These consist or thin-bedded, platy limestone, shale, and marl beds, which grade upward into a thick sequence of poorly fossiliferous calcareous sandstone, siltstone, and shale. A period of intense folding and erosion preceded the deposit of the non-marine Ahuichila Formation, of probable late Eocene and early Oligocene age. This formation was deposited with marked angular unconformity on all the older rocks, including the Villa Juarez Formation. Both, porphyritic and equigranular igneous rocks in the form of dikes, sills, plugs, and stocks intrude the bedded rocks of the area. They range in composition from quartz rhyolite porphyry to andesite and from granadiorite to monzonite. The rocks around the intrusive bodies have been metamorphosed irregularly as far as 100 m from the igneous contacts. Irregular tactite aureoles occur around intrusive bodies in the Descubridora district, west of Cerritos de Los Victorinos, and in the Sierra del Mimbre. Marble and recrystallized limestone is found west of Descubridora and in the Bajio del Bailon, and hornfels has formed in Cerrito de La Cruz and Cerrito de Las Liebres near San Pedro del Gallo, as well as in the southern part of the Sierra del Mimbre. Folowing emplacement of the intrusive bodies mineralizing solutions reacting with sedimentary rocks gave origin to the different mineralized zones in the region. The beginning of the Laramide Orogeny in the San Pedro del Gallo region is marked by Late Cretaceous uplift, which probably continued until middle or late Eocene time. Compressive forces acting in an east-west to northeast-southwest direction folded the Mesozoic strata into a series of narrow asymmetrical anticlines and synclines overturned to the east, with axial, planes almost parallel to the borders of the Coahuila Peninsula. Thrusting and faulting were important in the vicinity of San Pedro del Gallo. There is no conclusive evidence of large-scale post-Triassic and pre-Laramide deformation in the area. Extrusion of lavas ranging in composition from basalt to rhyolite, accompanied by extensive block faulting, occurred during Miocene and Pliocene time. Late Tertiary uplift began during the Pliocene. The streams were rejuvenated and there was increased erosion, which caused, together with a change of climate, the overloading of some streams and local blocking of drainage by alluvial fans in the valleys, giving rise to the Santa Ines Formation. Erosion, more than deposition is the dominant event at present. Contact metasomatic silver, lead, and copper deposits in the Aurora Limestone have been mined in the Descubridora, Parranderas , and Sierra del Mimbre districts. Fluorite and barite have been extracted from veins in the La Gloria Formation and the Aurora Limestone. Thin beds and seams of coal in the La Casita Formation were mined within the town limits of San Pedro del Gallo. No important mining activity exists at present in the area studied. The area has never been tested for oil.
