Geocronología de la Terraza Compleja de Arganda en el valle del río Jarama (Madrid, España)
La Terraza Compleja de Arganda (TCA), situada en el tramo bajo del río Jarama (Madrid), está formada por sucesivos apilamientos de secuencias fluviales denominados de abajo a arriba Arganda I, II, III y IV, en los que se han encontrado importantes yacimientos arqueológicos y paleontológicos del Pleistoceno (Áridos 1 y 2, Valdocarros o HAT), y numerosos conjuntos de industria lítica del Paleolítico inferior y medio. Hasta ahora, la única referencia cronológica disponible para la TCA era la proporcionada por el estadio evolutivo de los micromamíferos de los yacimientos Áridos 1 en Arganda I y Valdocarros en Arganda II. En este trabajo, se propone la equivalencia de las distintas unidades de la TCA con terrazas escalonadas y se establece un marco cronológico numérico, obtenido mediante dataciones de termoluminiscencia, luminiscencia ópticamente estimulada y racemización de aminoácidos. Arganda I (≈ T+30-32 m) se situaría hacia el final del MIS 11 o en el inicio del MIS 9, Arganda II (≈T+23-24 m) se correspondería con el inicio del MIS 7, Arganda III (≈T+18-20 m) se situaría entre el MIS 7 y el MIS 5, y Arganda IV comenzaría su deposición en el MIS 5 finalizando su sedimentación en el MIS 1 al sur de Arganda del Rey (Madrid)
Materiales neolíticos en el Valle del Jarama (Arganda, Madrid)
The Neolitihic materials from the site of «Arenero de Arganda» (Madrid), constitute an interesting addition to our knowledge of the Neolithic of the interior of the Iberian Peninsula. The materials suggest the need for a revision of the prevailing explanations of the nature of this Neolithic facies.En esta noticia se presentan materiales neolíticos del yacimiento del "Arenero de Arganda” (Madrid), constituyendo éstos una nueva aportación al panorama del Neolítico Interior.
Se propone, además, la necesidad de un replanteamiento en las estrategias explicativas que hasta ahora se han manejado en la interpretación del Neolítico meseteño
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
This work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
Imprints of massive inverse seesaw model neutrinos in lepton flavor violating Higgs boson decays
In this paper we consider a Higgs boson with mass and other properties compatible with those of the recently discovered Higgs particle at the LHC, and explore the possibility of new Higgs leptonic decays, beyond the standard model, with the singular feature of being lepton flavor violating (LFV). We study these LFV Higgs decays, H→lkl¯m, within the context of the inverse seesaw model (ISS) and consider the most generic case where three additional pairs of massive right-handed singlet neutrinos are added to the standard model particle content. We require in addition that the input parameters of this ISS model are compatible with the present neutrino data and other constraints, like perturbativity of the neutrino Yukawa couplings. We present a full one-loop computation of the BR(H→lkl¯m) rates for the three possible channels, lkl¯m=μτ¯, eτ¯, eμ¯, and analyze in full detail the predictions as functions of the various relevant ISS parameters. We study in parallel the correlated one-loop predictions for the radiative decays, lm→lkγ, within this same ISS context, and require full compatibility of our predictions with the present experimental bounds for the three radiative decays, μ→eγ, τ→μγ, and τ→eγ. After exploring the ISS parameter space we conclude on the maximum allowed LFV Higgs decay rates within the ISSThis work is supported by the European Union Grant No. FP7 ITN INVISIBLES (Marie Curie Actions, Grant No. PITN- GA-2011- 289442), by the CICYT through Grant No. FPA2012-31880, by the Spanish ConsoliderIngenio 2010 Programme CPAN (Grant No. CSD2007- 00042), and by the Spanish MINECO’s “Centro de Excelencia Severo Ochoa” Programme under Grant No. SEV-2012-0249.
