O Corral de Tránsito: Una cueva pastoral del Neolítico antiguo en el corazón de Sobrarbe
No full textSe trata de una cavidad de gran tamaño con una orientación idónea para el hábitat humano ya que el sol penetra hasta el fondo del abrigo y al mismo tiempo está protegido de los vientos del norte. Esta cavidad ha sido utilizada para el ganado durante muchos años y hasta hace poco tiempo se utilizaban diversos muros que compartimentan el espacio en varios "corrales". Hace años que se reconoció la presencia de restos arqueológicos en superficie. Los trabajos arqueológicos de Coro Trasito no han hecho más que comenzar y ya se puede constatar su gran potencial. Este yacimiento empieza a rellenar un vacío existente en la investigación de la prehistoria de los Pirineos en general y de Sobrarbe en particular
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
El pasado olvidado de la alta montaña. Ocupaciones prehistóricas en el Parque Nacional de Aigüestortes y Estany de Sant Maurici y sus implicaciones para la prehistoria de los Pirineos
No full textSe presentan los resultados de la investigación efectuada en el Parque Nacional d’Aigüestortes i Estany de Sant Maurici. En esta zona de alta montaña pirenaica el año 2000 no había prácticamente ningún yacimiento arqueológico documentado. En la actualidad el panorama ha cambiado mucho, siguiendo unas pautas homologables a lo que está sucediendo en otras zonas de los Pirineos orientales, en Andorra o Aquitania donde se han llevado a cabo programas de investigación sostenidos en el tiempo
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
Una història de llarga durada. L’ocupació humana del Parc Nacional d’Aigüestortes i Estany de Sant Maurici i àrees properes durant els darrers 10.000 anys
No full textFor the last 14 years, archaeological research at the National Park and its su-rrounding areas has facilitated the documentation of archaeological records with a chronological density, diversity and breadth that would have been unimaginable just a few years ago. This fact has opened the door to unders-tanding the processes of occupation and settlement in mountain areas above 1,500 m. Combining archaeological research with other paleoenvironmental studies has also enabled correlating the sequences of human occupation with the climatic dynamics and evolution of paleovegetation. The excavation of a small cave at Lake Coveta and the dolmen at Font dels Coms and, in recent years, the cave in Sardo complete the dataset currently available for this area, illustrating the main vectors that could have guided the Neolithic occupation of these high mountain areas
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
