Artículo escrito por un elevado número de autores, solo se referencian el que aparece en primer lugar, el nombre del grupo de colaboración, si le hubiere, y los autores pertenecientes a la UAM ; The Late Cretaceous (Campanian-Maastrichtian) fossil site of Lo Hueco was recently discovered close to the village of Fuentes (Cuenca, Spain) during the cutting of a little hill for installation of the railway of the Madrid-Levante high-speed train. To date, it has yielded a rich collection of well-preserved Cretaceous macrofossils, including plants, invertebrates, and vertebrates. The recovered fossil assemblage is mainly composed of plants, molluscs (bivalves and gastropods), actinopterygians and teleosteans fishes, amphibians, panpleurodiran (bothremydids) and pancryptodiran turtles, squamate lizards, eusuchian crocodyliforms, rhabdodontid ornithopods, theropods (mainly dromaeosaurids), and titanosaur sauropods. This assemblage was deposited in a near-coast continental muddy floodplain crossed by distributary sandy channels, exposed intermittently to brackish or marine and freshwater flooding as well as to partial or total desiccation events. The Konzentrat-Lagerstatt of Lo Hueco constitutes a singular accumulation of fossils representing individuals of some particular lineages of continental tetrapods, especially titanosaurs, eusuchians and bothremydid turtles. In the case of the titanosaurs, the site has yielded multiple partial skeletons in anatomical connection or with a low dispersion of their skeletal elements. A combination of new taxa, new records of taxa previously known in the Iberian Peninsula, and relatively common taxa in the European record compose the Lo Hueco biota. The particular conditions of the fossil site of Lo Hueco and the preliminary results indicate that the analysis of the geological context, the floral and faunal content, and the taphonomical features of the site provide elements that will be especially useful for reassess the evolutionary history of some lineages of European Late Cretaceous reptiles ; The fieldwork at Lo Hueco (2007-2009) was funded by ADIF (the state-owned company that administrate the Spanish railway infrastructures) through the company awarded the civil works (Ferrovial). The authors acknowledge the involvement and commitment to this task to the more-than-one-hundred technicians and assistants. The paleontological excavation was authorized by the Dirección General de Patrimonio y Museos de la Junta de Comunidades de Castilla-la Mancha whose acronym is 04.0392-P11. The excavation also received support from different estates of the Government of the Autonomous Community of Castilla-La Mancha (Presidencia de la JCCM, Consejería de Cultura, Consejería de Medio Ambiente, Delegación de la JCCM en Cuenca) and the City Council of Fuentes. Research at Lo Hueco was financed by the Spanish Ministerio de Ciencia e Innovación: CGL2009-12008, CGL2011-25894, CGL2009-10766, CGL2009-12143, and currently the proyect CGL2012-35199: "Estudio paleoambiental, faunístico y florístico del yacimiento del Cretácico Superior de Lo Hueco (Fuentes, Cuenca)". Part of this research has been also financed within the projects PEII11-0237-7926 of the Junta de Comunidades de Castilla-La Mancha. L.D. acknowledges a PICATA contract of the UCM-UPM Moncloa Campus of International Excellence (Spain). Preparation of the material has been partially developed by the Employment Workshop of Paleontological Restoration of Lo Hueco funded by the Fondo Social Europeo, Junta de Comunidades de Castilla-La Mancha, Spanish Ministerio de Empleo y Seguridad Social, and the Diputación Provincial de Cuenca

I toponimi di luoghi e di aree in relazione alle caratteristiche fisiche del terreno della provincia di Cuenca, in SpagnaIn Spagna la normalizzazione linguistica delle regioni (comunidades autónomas) con lingua propria diversa dallo spagnolo (fondamentalmente basco, catalano e galiziano) ha favorito, sin dalla costituzione dello stato democratico nel 1978, il recupero e la regolarizzazione dei nomi di luogo e delle loro diverse varianti; invece, le regioni in cui si parla esclusivamente il castigliano, come Cuenca, sono spesso prive di un corpus o di un repertorio di toponimi esaustivo e affidabile.In questo contesto si affronta uno studio toponimico, partendo dalla Linguistica e dalla Geografia, di una serie di vocaboli riportati nella cartografia di base della Spagna (Mappa Topografica Nazionale, 1:25.000), fra i quali si presta particolare attenzione ai nomi dei luoghi/località legati alle caratteristiche fisiche del territorio – substrato calcareo con abbondanza di terre argillose – come il toponimo charca (stagno), che fa riferimento a un accumulo d'acqua più o meno temporaneo e che si presenta in varie forme nella zona studiata: charco, chabarco, abanco, tollo, colocha, nava, poza, cenagal, ecc. Lo studio linguistico della variazione sinonimica di questi toponimi, insieme alla loro distribuzione geografica mediante il trattamento in un Sistema d'Informazione Geografica, consente di stabilire una serie di regole sul comportamento toponimico all'interno della Spagna.Étude des toponymes en rapport à la nature du sol. Le cas de l'expression de "bourbier", "marais" dans la province de Cuenca (Espagne)En Espagne l'ainsi-dite "normalisation linguistique" des zones avec une langue propre autre que l'espagnol (le basque, le catalan et le galicien) a donné lieu à une étude attentive des noms de lieux de ces endroits. Par contre, la toponymie des régions de l'Espagne où l'on parle castillan a été souvent négligée. C'est le cas de la province de Cuenca, dans lacommunauté actuelle de Castilla-La Mancha, au centre de l'Espagne.C'est dans ce contexte que notre recherche (qui forme partie d'un projet de recherche plus vaste) vise à brosser une étude toponymique à l'aide de la Toponymie et de la Géographie, sur des séries de toponymes trouvés dans la cartographie basique de l'Espagne (Mapa Topográfico Nacional, 1:25.000). Cette étude ne prétend nullement être exhaustive et se borne seulement aux noms de lieux (communes, hameaux, écarts, lieux-dits, etc.) appartenant à un champ sémantique inséparable des caractéristiques physiques du sol, bref un substrat calcaire avec abondance de terres argileuses, qui est la cause de l'emmagasinage des eaux de façon plus ou moins permanente. On trouve, en effet, de nombreux noms pour la description des lieux avec ces caractéristiques.Quelques-uns d'entre eux sont bien connus, comme charco, poza, cenagal, etc., mais d'autres sont à peu près aujourd'hui disparus de la langue vivante, comme chabarco, clocha, tollo, nava, etc. L'étude linguistique des variations para-synonymiques de ces toponymes étayée avec l'examen de leur distribution grâce à un Système d'Information Géographique nous permet d'établir à grands traits un tableau de quelques règles sur ce champ toponymique dans la province de Cuenca et ailleurs.

Using a variety of archival sources, this article traces the transition in Cuenca, Spain, from the bilateral family system that predominated in late medieval Castile to the final triumph of the patrilineal, agnatic family system in the seventeenth century. The central measure of this transition is the interlocking fates of the dowry and the arras (bride price). As the patriarchal, patrilineal family became entrenched during a period of demographic crisis, the price of dowries skyrocketed while the bride price declined in value and ultimately disappeared. The article includes a discussion of funding strategies for the dowry, inheritance law, and the degree of homogamy in marriages which relied on the dowry system.

[EN] X-ray diffraction, optical polarizing microscopy, scanning electron microscopy and electron microprobeto, have been used to analyse the diagenetic processes of isolated dinosaur bones and ribs attributed to an ornithopod dinosaur from Buenache de la Sierra (Upper Barremian, La Huérguina Formation). We also examine the geochemical and mineralogical bone mineralization of extant archosaurs (caiman and bird) for comparison. Diagenetic processes have modified the original chemical composition of the studied fragments of bones, as well as its crystallinity, which increases in the fossil samples. In recent bones, hydroxyapatite results the main mineral constituent, while in fossils is fluorapatite. We found two types of mineralogical arrangements: one group exhibiting the spongy structure completely collapsed forming breccias of bone fragments, and a second group with well preserved spongy structure but substituted by calcium carbonate. Calcite is the most abundant authigenic mineral infilling pores and fissures of the fossilized remains. The presence of pyrite in bone cavities suggests an early burial stage under euxinic conditions of a reductor environment. The biostratinomic and fossildiagenetic alterations allow us to conclude that the remains have two distinct taphonomic histories, and that the association undergone taphonomical resedimentation. ; [ES] Las diferentes técnicas utilizadas (difracción de rayos X, microscopio petrográfico, microscopio electrónico de barrido y microsonda electrónica) en el estudio de los restos óseos atribuidos a un ornitópodo del yacimiento Buenache de la Sierra (Baremiense superior, Formación La Huérguina) han permitido caracterizar los procesos diagenéticos. Se han analizado huesos de arcosaurios vivos (caimán y ave), para comparar la mineralogía y la geoquímica del material óseo. Los procesos diagenéticos han modificado la composición química original de los fragmentos de huesos estudiados, así como su cristalinidad, que aumenta en el caso de las muestras fósiles. En las costillas de los taxones actuales estudiados la fase mineral predominante es el hidroxiapatito y en las fósiles el fluorapatito. Encontramos dos tipos de organización mineralógica: un grupo presenta la estructura esponjosa totalmente colapsada, formando una brecha de esquirlas, mientras que en el segundo grupo la conservación histológica es evidente, aunque hay sustituciones parciales por carbonato cálcico. En el material óseo fósil el mineral autigénico más abundante es la calcita, que rellena los poros y fracturas. La presencia de restos de pirita en las cavidades del hueso indica que éstos se conservaron en un ambiente reductor en una etapa temprana del enterramiento. El estudio de los cambios bioestratinómicos y fosildiagenéticos nos permite concluir que se trata de una asociación resedimentada, con restos que han sufrido distintas historias tafonómicas. ; Este trabajo se ha realizado en el marco de los proyectos: CCGL2009-11838-BTE, MICINN y CGL2008-05813-CO2-01, MICINN (Spanish Government) and The Research Group CAM-UCM 910607. ; Peer reviewed

It is well known that in developed democracies the opposition tends to cooperate with the government. Spain is no exception: around 70 per cent of all 'organic laws' (constitutionally significant bills that require a parliamentary majority to be passed) are approved with the support of the main opposition party. We try to explain the variation in the level of consensus in the first seven legislative terms of the current Spanish democracy. We show that there are three key variables: the balance of power between government and opposition, the nature of the institutional actor that first proposes the bill, and the ideological significance of the bill.

La Serranía Alta de Cuenca, que coincide con el cuadrante nororiental de la provincia, limítrofe con las provincias de Guadalajara y Teruel, se caracteriza por ser un espacio montañoso con altitudes medias que oscilan entre los 1.400-1.700 m. Este territorio ha sufrido en los últimos cincuenta años un acusado descenso de la población así como el progresivo abandono de las actividades agrícolas y ganaderas tradicionales, lo que en la actualidad explica el acusado envejecimiento de la población y la casi desaparición de las actividades agropecuarias que está ocasionando una falta de diversificación económica en las rentas de estos municipios. Para intentar frenar los graves impactos provocados por la situación actual, analizaremos qué iniciativas de ámbito europeo (LEADER, Interreg), nacional y autonómico (Plan de Dinamización de Producto Turístico) han cristalizado en políticas de desarrollo sostenible dando lugar a numerosas inversiones y actuaciones en el territorio, entendiendo que todas ellas persiguen como finalidad última la mejora de la calidad de vida de los habitantes además de la promoción turística del territorio como elemento complementario y esencial de la economía de estos municipios, a la par que se conserva medioambientalmente una zona de alto valor natural mediante diversas figuras de protección (ENP, etc.). ; The "Serranía of Cuenca" is a mountainous space with average altitudes between 1.400-1.700 m. It is situated in the north-eastern edge of the province bordering the provinces of Guadalajara and Teruel. In the last fifty years, this huge territory has suffered a population decrease as well as a progressive abandon of the traditional agricultural and cattle farming activities. It difficult situation explains a marked ageing of inhabitants, the disappearance of the agricultural activities and almost the lack of economic diversification in the incomes of these municipalities. The article analyzes what initiatives from different origin (Europe, national, autonomic, etc.) like LEADER, Interreg, Plan of Tourist Product, etc. have crystallized in a political of sustainable development and have contributed with huge investments and actions to stop the serious impact in the local area. All of these measures follow the same objectives: the improvement of the quality of life of the inhabitants, the tourist promotion to be a complementary and an essential element of the local economies, and also the conservation of a natural value area with different figures of protection (ENP, etc.). ; Academia Andaluza de Ciencia Regional ; Instituto de Desarrollo Regional-UGR
