    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    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

    Construyendo una arqueología interdisciplinar en España: una macrohistoria centenaria

    Desde hace unas cuatro décadas, el interés en la historia de la arqueología en España ha experimentado un ascenso casi exponencial que ha tenido como consecuencia la producción de un enorme volumen de reflexiones sobre nuestro pasado disciplinar. A pesar de la enorme valía de lo publicado, llama poderosamente la atención el silencio sobre un tema que en estos mismos años estaba afectando en profundidad a la arqueología pero que, sin embargo, ha pasado desapercibido entre los historiadores de la disciplina: la interdisciplinariedad. Una explicación crítica sobre los orígenes y el desarrollo de este fenómeno se hacía, por tanto, necesaria, y tal tarea es la que nos proponemos afrontar en este escrito. Con la salvedad de algunos comentarios dispersos en la bibliografía, no sabíamos cuándo se había comenzado a emplear técnicas provenientes de ciencias diferentes a la propia disciplina para resolver problemas relacionados con el conocimiento sobre el pasado o, lo que es lo mismo, desconocíamos prácticamente todo sobre el momento en el que las prácticas interdisciplinares habían incidido en la arqueología.Este capítulo, así como todo el volumen en el que está inserto, es resultado en primer lugar, del proyecto Inter Arq, ref. HAR2016-80271-P, «Arqueología e interdisciplinariedad: una investigación arqueológico-histórica sobre las relaciones interdisciplinares en la Historia de la Arqueología española (siglos XIX y XX)», subvencionado por la Agencia Estatal de Investigación (AEI), el Fondo Europeo de Desarrollo Regional (FEDER) y la Unión Europea (UE). También es resultado del proyecto ArqueólogAs, «Recuperando la memoria: recorridos femeninos en la Historia de la Arqueología española» (PID2019-110748GB-I00) financiado por el Ministerio de Ciencia e Innovación, Agencia Estatal de InvestigaciónPeer reviewe

    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

    Introducción: microhistorias e interdisciplinariedad en arqueología

    No full text
    En estas cuatro últimas décadas, la historia de la arqueología ha experimentado un gran impulso en todo el mundo, y España ha sido uno de los países pioneros en este sentido. Internacionalmente se han tratado múltiples cuestiones: el anticuarismo, el coleccionismo, las instituciones, la profesionalización, el papel de la mujer en la arqueología, las dictaduras, el colonialismo, el nacionalismo, la fotografía y un largo etcétera. A pesar de la gran cantidad de esfuerzos en este campo que demuestra esta mínima selección que acabamos de mencionar, choca observar que el papel de la interdisciplinariedad en el desarrollo de la arqueología es un asunto que ha pasado prácticamente desapercibido al conjunto de los investigadores e investigadoras que han profundizado en estas cuestiones.Peer reviewe

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We 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

    Domestic activities at Early Neolithic Tell Seker al-Aheimar (Upper Khabur, Northeastern Syria) through phytoliths and spherulites studies

    The study centered on the identification of domestic activities and their spatial distributions in Tell Seker al-Aheimar, Syria. Phytolith and spherulite concentrations were indicative of specific locations where wild, domestic grasses and animal dung were deposited. These assemblages were related to food processing and foddering or grazing activities of herd animals. This pilot study has contributed to our understanding about the use of space at the site, and more specifically the manner in which vegetal resources and dung were exploited by Early Neolithic communities.[FR] L’étude s’insère dans le cadre des recherches sur l’identification des activités domestiques et leur distribution spatiale sur le site de Tell Seker al-Aheimar, Syrie. Les résultats obtenus à l’issue de l’étude des phytolithes et des sphérolithes ont permis la reconnaissance de concentrations de graminées cultivées, sauvages et de restes fécaux d’origine animale, qui mettent en évidence des pratiques agricoles et d’élevage. Ces études apportent des informations sur l’utilisation de l’espace au sein du site, ainsi que sur l’exploitation des plantes et des excréments des animaux domestiques pendant le Néolithique.This work was made possible by support from the University Museum- University of Tokyo, the Japan Society for Promotion of Sciences (Grant 20401030) and the Spanish Ministry of Innovation and Science– MICINN(HAR2009-06147-E/HIST). The first author was a post-doctoral fellow at the Institute of Archaeology– University College London, UCL (Spanish Ministry of Science and Education– MEC).Peer reviewe

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    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
