Condicionantes geomorfológicos y sedimentológicos para la conservación excepcional del bosque subfósil holoceno del valle de Sandria (Campisábalos, Guadalajara)
No full textEn este trabajo se muestran los resultados del estudio geomorfológico, sedimentológico y geofísico del relleno sedimentario holoceno del valle del arroyo de Sandria (Campisábalos, Guadalajara), como parte integrante del estudio de los yacimientos paleontológicos existentes en la zona. A partir del extraordinario material subfósil leñoso
encontrado en los yacimientos se han obtenido nuevos datos paleoecológicos que van a permitir obtener las pautas de cambio de la vegetación. El relleno sedimentario del yacimiento del arroyo de Sandria muestra una potencia que oscila entre los 2 y 6 m. Está formado por arenas finas, limos, margas orgánicas y turbas que se han interpretado como un ambiente de sedimentación de tipo lacustre y palustre. El cierre del valle fluvial de Sandria podría deberse a varias circunstancias, unidas o aisladas: la oclusión del valle a su salida por la progradación de un cono de deyección, la posible existencia de un pequeño alto estructural y/o la disolución diferencial del sustrato carbonatado que ha originado localmente pequeñas cubetas que coinciden con los depocentrosInstituto Geológico y Minero de España, EspañaEscuela de Ingeniería de Montes, Forestal y del Medio Natural, Universidad Politécnica de Madrid, EspañaDepartamento de Ingeniería del Terreno, Escuela Politécnica Superior de Ávila, Universidad de Salamanca, EspañaGeoland Services SL., Españ

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Occurrence of continuous Holocene pinewoods (Pinus sylvestris L.) in the Eastern Central System (Spain) inferred from macroremains. New data from the Sandria site
No full textThe present study of plant macroremains, wood fragments and pine cones from the eastern Central System (Ayllón Massif) for the upper Holocene establishes the presence in the area of Pinus sylvestris, Juniperus sp. and Betula sp. The occurrence of the Scots pine between ca. 4000 and 2000 yr BP allows us to confirm the natural origin of the species in the area at an altitude of 1350 m asl, a fact that clashes with numerous former phytosociological interpretations and which highlights the relevance of the current pine forests, as well as the need to include them within some status of legal protection. Furthermore, for the first time on the Iberian Peninsula, and considering the nearby Valdojos site, we employ only macroremains to demonstrate the presence of a pine forest practically throughout the Holocene, thus evidencing maximum conditions of stability and resilience for this type of plant community. As occurs with other vegetal formations identified by means of pollen analysis, this forest could have undergone radical alterations only in recent historical times as a result of anthropic action, as appears to be indicated by the evolution of the sedimentary basin of the Sandria valley.Departamento de Sistemas y Recursos Naturales, Universidad Politécnica de Madrid, EspañaInstituto Geológico y Minero de España, Españ
