Un hacha pulimentada reutilizada en el asentamiento vettón del Cerro de la Mesa (Alcolea de Tajo, Toledo)
No full textArtículo sobre una peculiar hacha pulimentada con muescas (reutilizada) que apareció en el yacimiento vettón del Cerro de la Mesa (Alcolea del Tajo, Toledo).Este artículo presenta una herramienta lítica procedente del asentamiento vettón del Cerro de la Mesa (Alcolea del Tajo, Toledo). Su diseño y función original como hacha pulimentada en algún momento de la Prehistoria Reciente fue alterada posteriormente, tal y como atestigua el dentado del filo y unas estrías laterales. Aunque la funcionalidad de este objeto en una casa de este poblado de la Edad del Hierro puede considerarse abierta, el análisis de las incrustaciones mediante SEM-EDX permiten considerar también que alguna vez pudo estar operando como una multiherramienta para abrasión de hueso y trabajo metalúrgico.This article presents a stone tool from the Vettonian settlement of Cerro de la Mesa (Alcolea del Tajo, Toledo). Originally designed and used as a polished stone axe during a phase of Recent Prehistory, its function was later modified, as evidenced by the serrations on the blade and lateral striae. While the exact purpose of this object within a house at this Iron Age site remains uncertain, SEM-EDX analysis of the inlays suggests that it may have functioned as a multi-tool for bone abrasion and metallurgical work.Depto. de Prehistoria, Historia Antigua y ArqueologíaFac. de Geografía e HistoriaTRUEpu

Prospección paleontológica superficial en el sector Villanueva-Alcolea-Lora del Río (Sevilla)
No full textEspañol: Se han caracterizado los yacimientos de invertebrados fósiles más relevantes (principalmente equinodermos y moluscos) de edad Mioceno superior (Tortoniense superior, -8-7 millones de años) localizados entre los términos de Villanueva del Río y Minas, Alcolea del Río y Lora del Río (Sevilla). Así mismo, se ha hecho un estudio acerca del patrimonio paleontológico conservado en las canteras y se sugieren las vías administrativas para proporcionar una mejor prevención y protección de los yacimientos. Inglés: The most important sites bearing fossil invertebrates (mainly echinoderms and molluscs) upper Miocene in age (upper Tortonian, -8,7 million years) located between Villanueva del Río y Minas, Alcolea del Río and Lora del Río (Seville) are characterized. As well, a study about the paleontological heritage preserved in the quarries are done and administrative solutions are suggested in order to give a best prevention and protection of this sites. Francés: Les plus importantes gisements d´invertébrés fossiles (échinodermes et molusques principalement) correspondant au Miocène supérieur (Tortonien supérieur, -8,7 m.a) situés entre les termes de Villanueva del Río y Minas, Alcolea del Río et Lora del Río (Seville) ont été caractérisés. Aussi, un étude sur le patrimoine paléontologique conservé dans les carrières a été présenté et plusieurs solutions administratives sont proposées pour améliorer la prévention et la protection des gisements
Entretien avec Diego Sanchez Alcolea : une journée sur l’herméneutique rabbinique à l’ICP
No full textLe 5 juin 2024, l’École des Langues et Civilisations de l'Orient ancien (ELCOA) a proposé une initiation aux méthodes d'interprétation juives dans le contexte du Nouveau Testament avec Diego Sanchez Alcolea, Directeur de la Chaire internationale d'Études Juives à l'Université Catholique Saint-Antoine de Murcie. Le monde juif a rapidement ressenti le besoin d'interpréter la Bible afin de comprendre la volonté de Dieu pour son peuple. Cela a donné naissance à toute une série de techniques et d..
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Kuhn on discovery and the case of Penicillin
No full textBook description: Nowadays, philosophy and methodology of science appear as a combination of novelty and continuity. This blend is clear both in the general approaches to science (those thought of as any science) and in the specific perspectives on every science, either formal or empirical. There are new topics for philosophical reflection, such as key issues in philosophy of medicine and central problems raised by neuroscience. Thus, new contents have brought attention to aspects that previously went almost unnoticed. In addition, there are new angles for philosophical study, such as the repercussion of society on scientific activity (in aims, processes, and results). But the background of the main philosophical and methodological trends of the twentieth century is, in many ways, still in place. Wenceslao J. Gonzalez is Professor of Logic and Philosophy of Science. He has been a visiting researcher at the Universities of St. Andrews, Münster and London (LSE), as well as Visiting fellow at the Center for Philosophy of Science, University of Pittsburgh. He has given lectures at the Universities of Pittsburgh, Stanford, Quebec and Helsinki. The conferences in which he has participated include those organized by the Universities of Uppsala, New South Wales, Bologna, and Canterbury (New Zealand). He has edited 21 volumes, among them are Philosophy and Methodology of Economics (1998) and Science, Technology and Society: A Philosophical Perspective (2005). Jesus Alcolea is Reader [Titular Professor] of Logic and Philosophy of Science. He undertook research at Smith College (Northampton, MA) with Th. Tymoczko. His focus of research has been on philosophy of mathematics: “Proof as a Way to Increase Understanding” (1996), “Fallibilism and Realism in Lakatos” (1999), “Vigencia del Pensamiento filosófico-matemático de Imre Lakatos” (2001), and “La extensión de los conceptos matemáticos” (2005)
