Investigaciones en el castro etrusco de La Castellina del Marangone, entre Tarquinia y Caere: vestigios de una ocupación romana no valorada
No full textLa Castellina, cuyo papel de frontera y de puerto abierto al Mediterráneo han determinado su historia, pudo ser el origen de la urbe de Civitavecchia en este litoral de Etruria Meridional. Hay indicios de diferente naturaleza que corroboran una presencia cartaginesa, hasta ahora no considerada, y que avalaría el establecimiento de contactos al menos desde el siglo IV a. C. Del mismo modo que algunas estructuras arquitectónicas y un cuantioso material mobiliar permiten afirmar que existió una ocupación residual en el yacimiento desde la fase tardo republicana al período del Bajo Imperio, que se superpone a las sucesivas fases protohistóricas y etruscas. Estas evidencias han sido estudiadas y documentadas a través de las excavaciones y estudios que han tenido lugar entre 1995 y 2011. Las diferentes categorías cerámicas, algunas importadas y otras regionales o locales, abarcan desde la vajilla ibérica, greco-itálica, sigillata, paredes finas, cerámicas comunes y cerámicas africanas ARSW.
Until the most recent excavations, few examples of ceramics from the Roman period were found on this site and the surrounding necropoleis. It is quite clear that the excavations opened since 1996 have produced noteworthy results. The vestiges brought to light in the central sector of the summit show evidence of the first destruction of the site, which took place during the late Roman period. Material goods, numerous, are distributed throughout the entire settlement, although with a greater concentration in the western sector. The objective now is to demonstrate this important presence from the last period of the Republic to Late Antiquity by means of the study of 235 selected examples of different categories of ceramic, some imported and others regional or local. These include Iberian, Greco-Italic, sigillata, thin-walled wares, common ceramics and African Red Slip Ware
Game theory of undirected graphical models
No full textAn -player game in normal form can be modeled via undirected discrete graphical models where the discrete random variables represent the players and their state spaces are the set of pure strategies. There exists an edge between the vertices of the graphical model whenever there is a dependency between the associated players. We study the Spohn conditional independence (CI) variety , which is the intersection of the independence model with the Spohn variety of the game . We prove a conjecture by the first author and Sturmfels that is of codimension in for a generic game with binary choices. We show that the set of totally mixed CI equilibria i.e., the restriction of the Spohn CI variety to the open probability simplex is a smooth semialgebraic manifold for a generic game with binary choices. If the undirected graph is a disjoint union of cliques, we analyze certain algebro-geometric features of Spohn CI varieties and prove affine universality theorems.30 pages, 4 figure
Revealing the history of sheep domestication using retrovirus integrations
No full textThe domestication of livestock represented a crucial step in human history. By using endogenous retroviruses as genetic markers, we found that sheep differentiated on the basis of their "retrotype" and morphological traits dispersed across Eurasia and Africa via separate migratory episodes. Relicts of the first migrations include the Mouflon, as well as breeds previously recognized as "primitive" on the basis of their morphology, such as the Orkney, Soay, and the Nordic short-tailed sheep now confined to the periphery of northwest Europe. A later migratory episode, involving sheep with improved production traits, shaped the great majority of present-day breeds. The ability to differentiate genetically primitive sheep from more modern breeds provides valuable insights into the history of sheep domestication
Range Unit Root (RUR) Tests: Robust against Nonlinearities, Error Distributions, Structural Breaks and Outliers
No full textSince the seminal paper by Dickey and Fuller in 1979, unit-root tests have conditioned the standard approaches to analysing time series with strong serial dependence in mean behaviour, the focus being placed on the detection of eventual unit roots in an autoregressive model fitted to the series. In this paper, we propose a completely different method to test for the type of long-wave patterns observed not only in unit-root time series but also in series following more complex data-generating mechanisms. To this end, our testing device analyses the unit-root persistence exhibited by the data while imposing very few constraints on the generating mechanism. We call our device the range unit-root (RUR) test since it is constructed from the running ranges of the series from which we derive its limit distribution. These nonparametric statistics endow the test with a number of desirable properties, the invariance to monotonic transformations of the series and the robustness to the presence of important parameter shifts. Moreover, the RUR test outperforms the power of standard unit-root tests on near-unit-root stationary time series; it is invariant with respect to the innovations distribution and asymptotically immune to noise. An extension of the RUR test, called the forward?backward range unit-root (FB-RUR) improves the check in the presence of additive outliers. Finally, we illustrate the performances of both range tests and their discrepancies with the Dickey?Fuller unit-root test on exchange rate series.Publicad
Apuntes iconográficos sobre los grabados de Jean de Courbes para los "Discursos de la nobleza de España" y la "Historia de la ciudad de Mérida" de Bernabé Moreno de Vargas
No full textEl presente trabajo se inscribe en el proyecto de investigación “Biblioteca digital Siglo de Oro IV” (BIDISO IV), FFI 2012-34362 (1/2/2013 a 31/12/2015), dirigido por la profesora Nieves Pena Sueiro y financiado por el Ministerio de Economía y Competitividad del Gobierno de España. De igual modo, su realización y presentación se ha llevado a cabo dentro de una Ayuda P.R.I. de la Junta de Extremadura y fondos FEDER “Una manera de hacer Europa. GR 15097” (Decreto 279/2014), a través del Grupo de Investigación “Patrimonio&ARTE. Unidad de Conservación del Patrimonio Artístico”, dirigido por la Dra. Pilar Mogollón Cano-Cortés.El presente trabajo aborda, desde un enfoque iconográfico, los programas alegóricos y simbólicos de las portadas grabadas e ilustraciones complementarias en sendas obras de orientación histórica del erudito eme¬ritense Bernabé Moreno de Vargas (c. 1576-1648), los “Discursos de la nobleza de España” (Madrid, 1622), y la “Historia de la ciudad de Mérida” (Madrid, 1633), todas ellas realizadas por el burilista de origen francés Jean de Courbes. Estas estampas constituyen, no solo un ilustrativo ejemplo de la moda barroca de sintetizar en imágenes de carácter alusivo y retórico la orientación o contenido generales de la obra, sino un testimonio de la amplia cultura histórica y humanística de su autor, familiarizado con los principales recursos y claves simbólicos de la cultura del siglo XVIII.This work uses an iconographic approach to consider the allegorical and symbolic series of etched covers and complementary illustrations of two historical works of scholar Bernabé Moreno de Vargas (c. 1576-1648), “Discursos de la nobleza de España” (Madrid, 1622), and “Historia de la ciudad de Mérida” (Madrid, 1633), all of which were created by the French engraver Jean de Courbes. These stamps are not only an illustrative example of the Baroque style of synthesizing the general orientation or content of a work through allusive and symbolic images, they are also testimony to the broad historic and humanistic culture of their author, familiarized with the principal resources and symbolic keys of 17th century culture.peerReviewe
Paleoenvironmental inferences on the Late Miocene hominoid-bearing site of Can Llobateres (NE Iberian Peninsula): An ecometric approach based on functional dental traits
No full textThis work is part of the Ph.D. Dissertation of the first author, in the framework of the Ph.D. Programme in Biodiversity of the Universitat Autònoma de Barcelona.Hispanopithecus laietanus from the Late Miocene (9.8 Ma) of Can Llobateres 1 (CLL1; Vallès-Penedès Basin, NE Iberian Peninsula) represents one of the latest occurrences of fossil apes in Western mainland Europe, where they are last recorded at ∼9.5 Ma. The paleoenvironment of CLL1 is thus relevant for understanding the extinction of European hominoids. To refine paleoenvironmental inferences for CLL1, we apply ecometric models based on functional crown type (FCT) variables-a scoring scheme devised to capture macroscopic functional traits of occlusal shape and wear surfaces of herbivorous large mammal molars. Paleotemperature and paleoprecipitation estimates for CLL1 are provided based on published regional regression models linking average FCT of large herbivorous mammal communities to climatic conditions. A mapping to Whittaker's present-day biome classification is also attempted based on these estimates, as well as a case-based reasoning via canonical variate analysis of FCT variables from five relevant biomes. Estimates of mean annual temperature (25 °C) and mean annual precipitation (881 mm) classify CLL1 as a tropical seasonal forest/savanna, only in partial agreement with the canonical variate analysis results, which classify CLL1 as a tropical rainforest with a higher probability. The former biome agrees better with previous inferences derived from fossil plants and mammals, as well as preliminary isotopic data. The misclassification of CLL1 as a tropical forest is attributed to the mixture of forest-adapted taxa with others adapted to more open environments, given that faunal and plant composition indicates the presence of a dense wetland/riparian forest with more open woodlands nearby. The tested FCT ecometric approaches do not provide unambiguous biome classification for CLL1. Nevertheless, our results are consistent with those from other approaches, thus suggesting that FCT variables are potentially useful to investigate paleoenvironmental changes through time and space-including those that led to the extinction of European Miocene apes

No full textBetween fetishism and survival : is the scientific article an academic commodity?
No full textThis article discusses the possible meanings of the intense prevailing concern in academic circles over the notion of research productivity, as reflected in an excess number of articles published in various scientific journals. The numerical accounting of articles published by researchers in scientific journals with renowned academic status serves to legitimize academics in their fields of work, in various ways. In this sense, we suggest that scientific articles take on aspects of merchandise-as-fetish, according to Marx's theory of use-value and exchange-value and Benjamin's exposure value. Meanwhile, the biological notions of selection and evolution are used as metaphorical elements in "bibliographic Darwinism". There are references as to the possibility many of the prevailing bibliometric concerns serve as instruments for econometric analysis, especially to orient and enhance cost-effectiveness analysis in research investments of various orders and types, from the point of view of their economic return
