Modelización del registro y proceso de datos espectrales, referidos a superficies líticas, en un ámbito arqueológico.

La determinación del origen de un material utilizado por el hombre en la prehistoria es de suma importancia en el ámbito de la arqueología. En los últimos años, los estudios de procedencia han utilizado técnicas que suelen ser muy precisas pero con el inconveniente de ser metodologías de carácter destructivo. El fenómeno de la minería a gran escala es una de las características que acompaña al Neolítico, de ahí que la revolución correspondiente a este periodo sea una de las etapas más importantes para la humanidad. El yacimiento arqueológico de Casa Montero es una mina de sílex neolítica ubicada en la Península Ibérica, de gran importancia por su antigüedad y su escala productiva. Este sitio arqueológico corresponde a una cantera de explotación de rocas silícicas desarrollada en el periodo neolítico en la que solamente se han encontrado los desechos de la extracción minera, lo cual incrementa la variabilidad de las muestras analizadas, de las que se desconoce su contexto económico, social y cultural. Es de gran interés arqueológico saber por qué esos grupos neolíticos explotaban de forma tan intensiva determinados tipos de material y cuál era el destino de la cadena productiva del sílex. Además, por ser una excavación de rescate, que ha tenido que procesar varias toneladas de material, en un tiempo relativamente corto, requiere de métodos expeditivos de clasificación y manejo de dicho material. Sin embargo,la implementación de cualquier método de clasificación debe evitar la alteración o modificación de la muestra,ya que,estudios previos sobre caracterización de rocas silícicas tienen el inconveniente de alterar parcialmente el objeto de estudio. Por lo que el objetivo de esta investigación fue la modelización del registro y procesamiento de datos espectrales adquiridos de rocas silícicas del yacimiento arqueológico de Casa Montero. Se implementó la metodología para el registro y procesamiento de datos espectrales de materiales líticos dentro del contexto arqueológico. Lo anterior se ha conseguido con la aplicación de modelos de análisis espectral, algoritmos de suavizado de firmas espectrales, reducción de la dimensionalidad de las características y la aplicación de métodos de clasificación, tanto de carácter vectorial como raster. Para la mayoría de los procedimientos se ha desarrollado una aplicación informática validada tanto por los propios resultados obtenidos como comparativamente con otras aplicaciones. Los ensayos de evaluación de la metodología propuesta han permitido comprobar la eficacia de los métodos. Por lo que se concluye que la metodología propuesta no solo es útil para materiales silícicos, sino que se puede generalizar en aquellos procesos donde la caracterización espectral puede ser relevante para la clasificación de materiales que no deban ser alterados, además, permite aplicarla a gran escala, dado que los costes de ejecución son mínimos si se comparan con los de métodos convencionales. Así mismo, es de destacar que los métodos propuestos, representan la variabilidad del material y permiten relacionarla con el estado del yacimiento, según su contenido respecto de las tipologías de la cadena operativa. ABSTRACT: The determination of the origin of a material used by man in prehistory is very important in the field of archaeology. In recent years the provenance studies have used techniques that tend to be very precise but with the drawback of being destructive methodologies. The phenomenon of mining on a large scale is a feature that accompanies the Neolithic period; the Neolithic revolution is one of the most important periods of humanity. The archaeological site of Casa Montero is a Neolithic flint mine located in the Iberian Peninsula of great importance for its antiquity and its scale. This archaeological site corresponds to a quarry exploitation of silicic rocks developed in the Neolithic period, in which only found debris from mining, which increases the variability of the samples analyzed, including their economic, social and cultural context is unknown. It is of great archaeological interest to know why these Neolithic groups exploited as intensive certain types of material and what the final destination of flint was in the productive chain. In addition, being an excavation of rescue that had to process several tons of material in a relatively short time requires expeditious methods of classification and handling of the material. However, the implementation of any method of classification should avoid the alteration or modification of the sample, since previous studies on characterization of silicic rocks have the disadvantage of destroying or partially modify the object of study. So the objective of this research wasthe modeling of the registration and processing of acquired spectral data of silicic rocks of the archaeological site of Casa Montero. The methodology implemented for modeling the registration and processing of existing spectral data of lithic materials within the archaeological context, was presented as an alternative to the conventional classification methods (methods destructive and expensive) or subjective methods that depend on the experience of the expert. The above has been achieved with the implementation of spectral analysis models, smoothing of spectral signatures and the dimensionality reduction algorithms. Trials of validation of the proposed methodology allowed testing the effectiveness of the methods in what refers to the spectral characterization of siliceous materials of Casa Montero. Is remarkable the algorithmic contribution of the signal filtering, improve of quality and reduction of the dimensionality, as well the proposal of using raster structures for efficient storage and analysis of spectral information. For which it is concluded that the proposed methodology is not only useful for siliceous materials, but it can be generalized in those processes where spectral characterization may be relevant to the classification of materials that must not be altered, also allows to apply it on a large scale, given that the implementation costs are minimal when compared with conventional methods.

Dinámica vegetal desde el tardiglaciar en la cuenca del Duero: interacciones con clima, fuego e impacto humano

La cuenca del Duero constituye un vasto territorio ibérico cuyo paisaje se encuentra actualmente muy alterado por la mano del hombre y es prácticamente imposible localizar alguna manifestación de su cubierta vegetal natural. Aunque la historia de la vegetación en los sectores central y oriental es relativamente bien conocida, en su mitad occidental los registros paleoecológicos estudiados hasta la fecha son prácticamente inexistentes. Esto hace que se desconozca la respuesta de la vegetación a las diferentes oscilaciones climáticas que se han producido desde el Último Máximo Glaciar, cuál fue el impacto de las diferentes culturas sobre el medio, cuándo se produjo una alteración profunda de la vegetación natural y cuál ha sido la historia de los incendios. Este último aspecto, el papel e importancia de los incendios, reviste un especial interés en la península Ibérica dada su situación geográfica y climática dentro de la cuenca Mediterránea, donde el fuego es un factor ecológico de primer nivel. Las distintas técnicas paleoecológicas son las más adecuadas para abordar todas estas preguntas. De este modo, los avatares de la vegetación a través del tiempo se han reconstruido mediante el análisis polínico y de macrofósiles, el impacto humano se ha trazado utilizando indicadores polínicos ligados a actividades antrópicas y esporas de hongos coprófilos, estudiándose los incendios a partir del registro de partículas microscópicas de carbón. La alta resolución temporal y taxonómica alcanzada en estos análisis, así como la amplia superficie abarcada con los yacimientos estudiados, hacen que la información obtenida sea altamente detallada y complete el conocimiento que se tiene sobre la cuenca del Duero. El Tardiglaciar se registra por primera vez en la Meseta Norte Ibérica en la secuencia de Ayoó de Vidriales, donde una vegetación esteparia prácticamente desarbolada domina durante los periodos fríos. Durante el interestadial Bølling/Allerød la expansión forestal (pinos, abedules) fue muy leve y tardía y fue interrumpida bruscamente por el Dryas Reciente. Al final del Dryas Reciente o al inicio del Holoceno se produjo una acusada y rápida expansión de los bosques. Esta dinámica sugiere que no hubo refugios glaciares importantes en esta zona de la Meseta durante el “Mystery Interval”, aparentemente el periodo más frío y seco. Los incendios fueron muy escasos, aumentando de forma muy brusca al inicio del Holoceno por el aumento de biomasa y las condiciones relativamente cálidas y secas. A partir de los registros de Ayoó y El Maíllo se consolida la importancia del gradiente oceanicidad-continentalidad en el Sistema Central y la Meseta Norte, que se manifiesta principalmente en la dominancia más prolongada de los pinares hacia el interior. Además, otra de las principales contribuciones de la presente tesis es proporcionar evidencia sobre la sucesión de distintos tipos de bosques en el noroeste de la Meseta, precisando el marco temporal en el que suceden. Así, se ha constatado que hubo un máximo desarrollo del bosque caducifolio durante el Holoceno medio en Ayoó de Vidriales y una baja incidencia del fuego que sugieren que el clima fue más húmedo que en el Holoceno inicial. El estudio de macrofósiles leñosos ha permitido detectar procesos que con el análisis polínico habrían pasado desapercibidos, como la persistencia hasta el Holoceno final de Pinus sylvestris en la sierra del Teleno y la sustitución de P. sylvestris por P. pinaster en la sierra de Francia durante el Holoceno inicial. También el estudio de los carbones procedentes de los arenales de Tierra de Pinares han proporcionado la prueba definitiva de la naturalidad de los pinares de P. pinaster. El impacto humano se detecta temprano en las secuencias del oeste de la cuenca del Duero, durante el Neolítico, aunque ha sido mucho más acusado desde la Edad del Hierro (ca 2700-2500 años cal BP). Para la detección del impacto humano temprano ha sido clave el análisis de esporas de hongos coprófilos, cuyo análisis fue incorporado en la secuencia de Ayoó de Vidriales. Una de sus principales consecuencias fue el establecimiento de comunidades de matorral (brezales, piornales) sobre amplias extensiones del occidente de la cuenca del Duero, vinculado al recrudecimiento de los regímenes de incendios. A pesar de que los incendios han sido ecológicamente importantes desde el inicio del Holoceno, los cambios introducidos por el hombre en sus regímenes sobrepasaron la resiliencia de los bosques originales, lo cual condujo a su sustitución sostenida por matorrales. ABSTRACT The Duero Basin constitutes a vast Iberian territory which is currently strongly disturbed due to human activities, so it is very difficult to find any remnant of the natural vegetation. Vegetation history for the eastern and western sectors of the Basin is relatively well-known but, in contrast, there is an almost complete lack of palaeoecological record in the western area. Consequently, there exists a profound ignorance about vegetation responses to the climatic oscillations occurred since the Last Glacial Maximum, the environmental impact of the different cultures, when a severe disturbance of the natural vegetation took place and fire history. The last question, the role and importance of fire, has a special interest in the Iberian Peninsula due to its geographic and climatic framework, the Mediterranean Basin, where fire is a major ecological factor. The diverse palaeoecological techmiques are the most suitable tools to address all these questions. Thus, vegetation shifts through time have been reconstructed using pollen and macrofossil analyses, human impact has been tracked by means of anthropogenic pollen indicators and dung fungal spores, while fire history has been studied from the quantification of microscopic charcoal particles. The high taxonomic and time resolution attained along with the extensive surface covered by the studied sites provide detailed information very useful to complete the knowledge on landscape dynamics in the Duero Basin. The Lateglacial is recorded for the first time in the Northern Iberian Plateau in the sequence from Ayoó de Vidriales, showing that almost treeless steppic vegetation dominated during the cold periods. Tree expansion (pines, birches) was late and slight during the Bølling/Allerød interstadial and was sharply interrupted by the Younger Dryas (YD) climatic reversal. By the end of the YD or the onset of the Holocene, a rapid forest expansion occurred. This forest dynamics suggests an absence of important glacial refugia for trees in this area of the Plateau during the Mystery Interval, apparently the coldest and driest period. Fires were fairly rare, increasing abruptly at the beginning of the Holocene due to the relatively warm and dry climate and the accumulation of biomass. The records from Ayoó and El Maíllo reinforce the role of the oceanicity-continentality gradient in the vegetation history of the Iberian Central Range and the Iberian Northern Plateau, reflected mainly in the longer dominance of pine forests towards inland areas. Further, another important contribution of this PhD Thesis is providing evidence on the succession of different forest types in the northestern fringe of the Plateau, specifying the chronological framework. A maximum of deciduous forest development and low fire activity have been detected in Ayoó de Vidriales during the mid-Holocene, suggesting that climate was wetter than in the early Holocene. The study of woody macrofossils has allowed detecting processes which would have remained unnoticed using pollen analysis alone, such as the persistence of Pinus sylvestris until the late Holocene in the Teleno Mountains and the early Holocene replacement of P. sylvestris with P. pinaster in the sierra de Francia range. The study of macroscopic charcoal fragments from palaeosols of the Tierra de Pinares has also provided the definitive proof of naturalness for the P. pinaster stands gorwing over this area at present. Early human impact, during the Neolithic, has been detected in the sequences from the western sector of the Duero Basin, although human disturbance has been more severe from the Iron Age onwards (ca 2700-2500 cal yr BP). The analysis of coprophilous fungi incorporated in the sequence of Ayoó de Vidriales has played a key role in recognizing that early human impact. One of the main consequences of human disturbance was the establishment of shrubland communities (heaths, brooms) over huge areas of the western Duero Basin, linked to severe and/or frequent fires. Despite fires has been ecologically important since the onset of the Holocene, human-induced changes in fire regimes have exceeded the resilience of original forests leading to a sustained replacement with shrublands.

Nota sobre un petroglifo y otros hallazgos prehistoricos en el monte de Campicerrado y sierra de Toranzo (Matalebreras, Ólvega, Soria)

Se da noticia retroactiva del hallazgo en los años cincuenta del siglo pasado de una gran piedra suelta labrada con marcas y signos rupestres alfabetiformes de carácter simbólico de difícil adscripción cultural, aunque se piensa pudieran corresponder al Neolítico. En el mismo monte de Campicerrado, junto a la Fuente de La Puerca, se han encontrado tres puntas de sílex con pedúnculo y aletas del Solutrense. It gives retroactive news of finding, in the fifties of the last century, of a large loose stone hewn rupestrian markings and pseudo alphabetical signs which are symbolic (Petroglyphs) and difficult assignment culture, although it is thought may correspond to Neolithic. In the same Campicerrado mount next to the Fuente de La Puerca, were found three flint arrowheads with peduncle and fins of Solutrean period.

Customer Relationship Management-PeopleSoft CRM

1 RESUMEN 1.1 Resumen (español) El intercambio y comercio tanto de bienes como servicios se remonta a tiempos inmemoriales dentro de la historia de la humanidad. Desde sus inicios tempranos con el intercambio o trueque de productos en el Neolítico hasta nuestra época híper globalizada, en la que existen clientes potenciales en el otro extremo del mundo, podemos decir que se ha recorrido un largo camino. Con el paso del tiempo y la evolución de la sociedad y la tecnología, así como la evolución empresarial, se ha visto necesario la implementación de estrategias para lograr la fidelización y satisfacción de los clientes. De esta forma entendimos que ya no valía simplemente con vender un producto a un cliente, si no que si queríamos establecer una relación continúa con el mismo, debíamos lograr su satisfacción y por tanto su fidelización. Como forma de extender la relación más allá de una simple venta, las empresas modernas empezaron a implementar diversas estrategias. De esta forma aparecieron los primeros centros de atención al cliente, las primeras aplicaciones hechas a medida para dar soporte a los clientes y por fin los sistemas CRM tal y como los concebimos hoy día. El presente proyecto fin de carrera da una explicación de dichos sistemas indicando cuáles son sus objetos fundamentales y cómo implementan la estrategia CRM y profundiza en uno de los sistemas CRM más utilizados: PeopleSoft CRM, dando una explicación detallada de dicho sistemas así como de los conceptos y lenguaje de programación de dicho sistema CRM. 1.2 SUMMARY (ENGLISH) The exchange and trade of goods as well and services goes back to ancient times in the history of mankind. Since its early beginning with the bartering of products in the Neolithic to our globalized hyper era, in which there are potential customers on the other side of the world, we can say that it has come a long way. After a certain length of time, the society and technology evolution, and also the enterprise development, has been necessary to implement strategies to achieve customer loyalty and satisfaction. We understood in this way that it no longer simply worth to sell a product to a customer, otherwise if we wanted to establish a relationship continues with the same, we should ensure their satisfaction and thus their loyalty. As a way to extend the relationship beyond a simple sale, modern enterprises began to implement several strategies. Therefore appeared the first customer service centers, the first applications tailored to support customers and finally the CRM systems as we know it today. This final project gives an explanation of such systems by indicating what the core objects are and how to implement the CRM strategy, deeping into one of the most widely used CRM systems: PeopleSoft CRM, and also giving a detailed explanation of this system and its programming language.

Protein diagenesis in Patella shells: implications for amino acid racemisation dating

Se analiza la racemización de aminoácidos en proteínas inter e intracristalinas en conchas de Patella y su utilización como herramienta geocronológica, fundamentalmente empleadas en yacimientos arqueológicos.The inter- and intra-crystalline fractions of Patella vulgata limpets recovered from archaeological sites in Northern Spain (covering Neolithic, Mesolithic, Magdalenian, Solutrean, and Aurignacian periods) were examined for amino acid composition and racemisation over time. The calcitic apex and rim areas of the shells were found to probably be composed of similar proteins, as the D/L values and amino acids were comparable and varied in the same way with increasing age; however, the mineral structures present in these areas differed. The aragonitic intermediate part of the shell showed a distinctly different amino acid composition and mineral structure. The main protein leaching from the inter-crystalline fraction occurred within the first 6000 yr after the death of the organism. In contrast, the intra-crystalline fraction — comprised of a different protein composition than the inter-crystalline fraction — appeared to behave as a closed system for at least 34 ka, as reflected by the lack of a significant decrease in the amino acid content; however, changes in the amino acid percentages occurred during this period. The concentration of aspartic acid remained almost constant with age both in inter- and intra-crystalline proteins, and its contribution to the total amino acid content increased with age at the expense of other amino acids such as glutamic acid, serine, glycine and alanine. Temperature is thought to play a key role in the amino acid racemisation of P. vulgata and could explain why in the localities belonging to the Gravettian and Solutrean period, which formed during relatively cold conditions, D/L values were similar to those detected in shells from sites formed during the Magdalenian.

Evolución de la vegetación en el sector biogeográfico Castellano Cantábrico durante el Cuaternario Final, a través del registro tobáceo

En esta memoria de Tesis Doctoral se aborda el estudio paleobotánico de seis yacimientos tobáceos situados en las localidades burgalesas de Tubilla del Agua, Sedano, Herrán, Tobera y Frías, y en la alavesa de Ocio. El registro fósil encontrado en estos afloramientos se analiza de forma conjunta con el objetivo de conocer la evolución de la vegetación en el sector biogeográfico Castellano Cantábrico. Este sector se considera el territorio para el cual los hallazgos paleobotánicos son representativos y extrapolables, en tanto que constituye una región homogénea desde el punto de vista florístico, que abarca todos los yacimientos prospectados. El contexto temporal en el que se enmarca este estudio es el final del Cuaternario, desde el Pleistoceno Medio hasta la actualidad. Este intervalo se ha establecido a partir de la edad de los depósitos estudiados, la cual ha sido determinada —para los yacimientos de los que no se disponía de edades fiables— mediante la datación de muestras extraídas de las diferentes unidades litológicas identificadas. Para ello han sido empleadas las técnicas de carbono-14, desequilibrio de las series del uranio y racemización de aminoácidos. Los resultados geocronológicos obtenidos junto con el análisis geomorfológico de los yacimientos han permitido vincular la génesis de las 13 unidades litológicas identificadas con diferentes estadíos climáticos. Estos abarcan un amplio rango de condiciones ambientales, desde las más extremas del Último Máximo Glacial, hasta las más benignas de los Estadíos Isotópicos Marinos interglaciares 1 y 5. Como resultado de la prospección de los depósitos de toba fueron recuperados 1.820 fósiles, la mayoría impresiones foliares, pero también moldes de estróbilos femeninos, ramas y corteza, así como 42 carbones y restos subfósiles de Pinus sp. La identificación taxonómica de estos restos se ha realizado fundamentalmente a partir del análisis de caracteres diagnósticos morfológicos. Como resultado de ello, han sido descritos 28 taxones pertenecientes a las subclases Bryidae, Polypodiidae, Pinidae y Magnoliidae. La flora de los yacimientos estudiados se puede clasificar en tres grupos en función de sus requerimientos ecológicos: (i) uno formado por dos especies de alta tolerancia a la continentalidad —Pinus nigra y Quercus faginea—, las cuales aparecen bien representadas en la mayoría de los depósitos; (ii) otro constituido fundamentalmente por un conjunto de árboles y arbustos que habitualmente tienen el papel de especies acompañantes en los bosques ibéricos submediterráneos y eurosiberianos; y (iii) un tercer grupo compuesto por taxones hidrófitos o edafohigrófilos asociados al ecosistema del fitohermo activo y la vegetación de ribera. En el capítulo de Discusión se propone y analiza la hipótesis de que P. nigra y Q. faginea habrían sido las especies protagonistas de la vegetación zonal del sector Castellano Cantábrico durante el Cuaternario Final. Estas podrían haber persistido como tal incluso durante las épocas más frías, debido a su amplia valencia ecológica y a la capacidad de reproducirse vegetativamente en el caso del quejigo. Por el contrario, los taxones mesofíticos y eurosiberianos pudieron haber sufrido la expansión y retracción de sus poblaciones al ritmo de las oscilaciones climáticas. Sin embargo, la orografía diversa del sector Castellano Cantábrico proporciona emplazamientos en los que se combinan las diversas variables fisiográficas, de tal forma que pudieron haber existido microrrefugios en los que encontraron cobijo algunos taxones mesotérmicos y eurosiberianos durante los periodos glaciales. Por último, la historia evolutiva reciente de la vegetación de este territorio ha estado marcada por la acción antrópica, la cual empezó a ser manifiesta a partir del Neolítico. Esta se tradujo en la degradación y reducción de la cubierta forestal, así como en la extinción del pino laricio del Sector Castellano Cantábrico en los dos últimos milenios. ABSTRACT This PhD Dissertation focuses in the study of six tufa formations located nearby the villages of Tubilla del Agua, Sedano, Herrán, Tobera y Frías, all of them in the province of Burgos, and Ocio, which belongs to the province of Álava. We analyze the palaeobotanical archives of these sites with the purpose of unveiling and understanding the evolution of the vegetation of the Castilian Cantabrian biogeographical sector. This area is considered to be the territory that is represented in the palaeobotanical sample of the studied tufa archives. It is the homogeneous phitogeographical area with the lowest rank that include all the sites. The time frame of this study is the last part of the Quaternary, since the Middle Pleistocene to the present time. This interval is defined by the age of the tufa deposits, which were dated —for the ones that there were not available datings— throughout the analysis of 20 tufa samples taken from the 13 identified lithostratigraphic units. The age of the samples has been determined by using the methods of radiocarbon, U-Th dating and amino acid racemization. Chronological results, along with the chronostratigraphic study of the sites has allowed us to relate the build-up of the 13 identified lithostratigraphic units with different climatic stages. These structures were deposited in a wide range of climatic conditions, from the most extreme ones of the Last Glacial Maximum, to the warmer ones of the Marine Isotopic Stages 1 and 5. A total of 1,820 fossils were recovered from the tufa deposits, most of them were leaf impressions, but also pine cones, branches and bark moulds, along with charcoal and Pinus nigra macro remains. The taxonomical identification of these remains has been done mainly through the analysis of morphological traits. As a result of this process, 28 taxa belonging to the subclass of Bryidae, Polypodiidae, Pinidae and Magnoliidae were identified. The persistency of some taxa can be traced along different climatic stages in this fossil record. This fossil flora can be classified in three different groups: (i) the first one would be composed of two species with high continental climate tolerance —Pinus nigra y Quercus faginea—, which can be found in most of the deposits, (ii) the second group would be mostly formed by trees and shrubs that usually grow in the Iberian forests as an accessory species and (iii) the third one is composed of hydrophytes or hydrophilic taxa associate to the streams, riparian zones or the active tufa ecosystem. In the Discussion chapter we propose and analyse the hypothesis that P.nigra and Q. faginea were the main species of the zonal vegetation of the Castilian Cantabrian biogeographical sector during the last part of the Quaternary. This species could have persisted due to their wide ecological amplitude and also due to the capacity of asexual reproduction in the cases of the oak. On the other hand, mesophitic taxa could have suffered the retraction and expansion of their population following the climate oscillations. However, the diverse orography of the Castilian Cantabrian biogeographical sector provides a variety of combinations of physiographic variables, which could have been suitable refuges for some of the mesophitic taxa. The recent evolutionary history of the vegetation in this territory has been affected by human activities, which started to be relevant since the Neolithic. This led to a reduction of the forests and eventually, to the extinction of P. nigra in the Castilian Cantabrian biogeographical sector in the last two thousands of years.

AS BRIGAS DIVINAS DE INANA: Reconstrução feminista de repressão e resistência em torno de uma deusa suméria

As análises desta tese, baseadas numa hermenêutica feminista libertadora, têm como centro a figura de Inana, a deusa mais importante e mais popular da Suméria, que predominou, sob o nome de I tar, também nos panteões mesopotâmicos posteriores. O Capítulo 1 oferece uma reconstrução da vida na Suméria, desde os tempos neolíticos até os inícios do Período Babilônico Antigo (aproximadamente de 5000 a 2000 aEC), com especial atenção para dados sobre mulheres e para aspectos de gênero. O Capítulo 2 apresenta documentos pré-sargônicos, iconográficos e filológicos, relacionados com a figura e o culto de Inana, oferecendo as primeiras reflexões sobre aspectos particulares e conflitos que mostram sua posição especial na religião na Suméria e na sua crescente patriarcalização. No Capítulo 3, esses aspectos e conflitos são discutidos enfocando tradições de Inana como Senhora da Eana, dos Me e de Kur, com especial atenção para os mitos Inana e a Eana , Inana e os Me e Inana e o Inframundo (ETCSL 1.3.5; 1.3.1; 1.4.1). É mostrado que o mito Inana e a Eana é o resultado de manipulações para legitimar o culto de An nesse templo de Inana, que Inana e os Me reflete atitudes de resistência contra tentativas de seu desapoderamento, e que Inana e o Inframundo é composto de mitos diferentes que evidenciam vários conflitos relacionados com funções e poderes de Inana. Desse modo mostra-se que os conflitos em torno de Inana refletem repressões e resistências humanas no âmbito de uma sociedade quiriarcal e da crescente patriarcalização de sua religião. Embora a atuação política e religiosa de mulheres em sociedades de hoje não necessite de legitimações a partir de exemplos provenientes de religiões antigas, a reconstrução e memória feministas de tais exemplos podem servir de estímulo para tal atuação quando busca construir uma outra imagem do divino e quando luta por um mundo de igualdade em direitos e dignidade para todas as pessoas.(AU)

A “REVOLTA” DE JEÚ E A ESTELA DE DÃ: Um Estudo Em 2 Reis 10,28-36

A pesquisa tem por objetivo trabalhar o evento da Revolta de Jeú, em conjunto com a Estela de Dã, tendo como ponto de partida para tal, a exegese da perícope de 2 Reis 10-28,36. A história Deuteronomista apresenta o ato da Revolta de Jeú como sendo um feito demasiadamente importante, na restauração do culto a Javé em Israel, a partir de um contexto onde o culto a outras divindades, em Israel Norte, estava em pleno curso. No entanto, a partir da análise conjunta da Estela de Dã, que tem como provável autor o rei Hazael de Damasco, somos desafiados a ler esta história pelas entrelinhas não contempladas pelo texto, que apontam para uma participação ativa de Hazael, nos desfechos referentes a Revolta de Jeú, como sendo o responsável direto que proporcionou a subida de Jeú ao trono em Israel, clarificando desta forma este importante período na história Bíblica. Para tal análise, observar-se-á três distintos tópicos, ligados diretamente ao tema proposto: (1) A Revolta de Jeú e a Redação Deuteronomista, a partir do estudo exegético da perícope de 2 Reis 10,28-36, onde estão descritas informações pontuais sobre período em que Jeú reinou em Israel; (2) Jeú e a Estela de Dã, a partir da apresentação e análise do conteúdo da Estela de Dã, tratando diretamente dos desdobramentos da guerra em Ramote de Gileade, de onde se dá o ponto de partida à Revolta de Jeú; e por fim (3) O Império da Síria, onde a partir da continuidade da análise do conteúdo da Estela de Dã, demonstraremos a significância deste reino, além de apontamentos diretamente ligados ao reinado de Hazael, personagem mui relevante no evento da Revolta de Jeú.

Genetic epidemiology of single-nucleotide polymorphisms

On the causal hypothesis, most genetic determinants of disease are single-nucleotide polymorphisms (SNPs) that are likely to be selected as markers for positional cloning. On the proximity hypothesis, most disease determinants will not be included among markers but may be detected through linkage disequilibrium with other SNPs. In that event, allelic association among SNPs is an essential factor in positional cloning. Recent simulation based on monotonic population expansion suggests that useful association does not usually extend beyond 3 kb. This is contradicted by significant disequilibrium at much greater distances, with corresponding reduction in the number of SNPs required for a cost-effective genome scan. A plausible explanation is that cyclical expansions follow population bottlenecks that establish new disequilibria. Data on more than 1,000 locus pairs indicate that most disequilibria trace to the Neolithic, with no apparent difference between haplotypes that are random or selected through a major disease gene. Short duration may be characteristic of alleles contributing to disease susceptibility and haplotypes characteristic of particular ethnic groups. Alleles that are highly polymorphic in all ethnic groups may be older, neutral, or advantageous, in weak disequilibrium with nearby markers, and therefore less useful for positional cloning of disease genes. Significant disequilibrium at large distance makes the number of suitably chosen SNPs required for genome screening as small as 30,000, or 1 per 100 kb, with greater density (including less common SNPs) reserved for candidate regions.

Genetic evidence for different male and female roles during cultural transitions in the British Isles

Human history is punctuated by periods of rapid cultural change. Although archeologists have developed a range of models to describe cultural transitions, in most real examples we do not know whether the processes involved the movement of people or the movement of culture only. With a series of relatively well defined cultural transitions, the British Isles present an ideal opportunity to assess the demographic context of cultural change. Important transitions after the first Paleolithic settlements include the Neolithic, the development of Iron Age cultures, and various historical invasions from continental Europe. Here we show that patterns of Y-chromosome variation indicate that the Neolithic and Iron Age transitions in the British Isles occurred without large-scale male movements. The more recent invasions from Scandinavia, on the other hand, appear to have left a significant paternal genetic legacy. In contrast, patterns of mtDNA and X-chromosome variation indicate that one or more of these pre-Anglo-Saxon cultural revolutions had a major effect on the maternal genetic heritage of the British Isles.

Geographical structuring in the mtDNA of Italians.

Geographical patterns of mtDNA variation were studied in 12 Italian samples (1072 individuals) by two different spatial autocorrelation methods. Separate analyses of the frequencies of 12 restriction morphs show North-South clines, differences between Sardinia and the mainland populations, and the effects of isolation by distance. A recently developed autocorrelation statistic summarizing molecular similarity at all sites (AIDA; autocorrelation index for DNA analysis) confirms the presence of a clinical pattern; differences between random pairs of haplotypes tend to increase with their geographical distance. The partition of gene diversity, however, reveals that most variability occurs within populations, whereas differences between populations are minor (GST = 0.057). When the data from the 12 samples are pooled, two descriptors of genetic variability (number of polymorphic sites and average sequence difference between pairs of individuals) do not behave as expected under neutrality. The presence of clinal patterns, Tajima's tests, and a simulation experiment agree in suggesting that population sizes increased rapidly in Italy and Sicily but not necessarily so in Sardinia. The distribution of pairwise sequence differences in the Italian peninsula (excluding Sardinia) permits a tentative location of the demographic increase between 8000 and 20,500 years ago. These dates are consistent with archaeological estimates of two distinct expansion processes, occurring, respectively, in the Neolithic and after the last glacial maximum in the Paleolithic. Conversely, there is no genetic evidence that such processes have had a major impact on the Sardinian population.

Genetics and the origin of European languages.

A new set of European genetic data has been analyzed to dissect independent patterns of geographic variation. The most important cause of European genetic variation has been confirmed to correspond to the migration of Neolithic farmers from the area of origin of agriculture in the Middle East. The next most important component of genetic variation is apparently associated with a north-south gradient possibly due to adaptation to cold climates but also to the differentiation of the Uralic and the Indo-European language-speaking people; however, the relevant correlations are not significantly different from zero after elimination of the spatial autocorrelation. The third component is highly correlated with the infiltration of the Yamna ("Kurgan") people, nomadic pastoralists who domesticated the horse and who have been claimed to have spread Indo-European languages to Europe; this association, which is statistically significant even when taking spatial autocorrelations into account, does not completely exclude the hypothesis of Indo-European as the language of Neolithic farmers. It is possible that both expansions were responsible for the spread of different subfamilies of Indo-European languages, but our genetic data cannot resolve their relative importance.

Estudio de materiales de construcción neolíticos mediante diferentes técnicas instrumentales

Se han aplicado técnicas de análisis instrumental (FRX, DRX, ATR-IR, TG-ATD, SEM-EDX, MO) al estudio de fragmentos constructivos de época neolítica obtenidos de diferentes yacimientos de la Provincia de Alicante (España). La secuencia y el orden de aplicación de las técnicas se fija en función de las características y la cantidad disponible de cada muestra, estableciéndose con ello un protocolo de trabajo que se aplica siempre al resto de muestras, lo que nos permite comparar los resultados entre sí. El uso de dichas técnicas nos ha permitido la caracterización de los fragmentos constructivos, lo que nos ha llevado a conocer el grado de tecnología alcanzado por estas sociedades, sugiriéndonos que podíamos estar ante los inicios de la aplicación de la tecnología de la cal en esta zona de la Península Ibérica. En este trabajo se presenta una visión global de los resultados obtenidos hasta el momento.
