    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

    Variations on the Author

    “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 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

    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

    Seven years ground-based intensive care transport at a large general hospital: An analysis of the range of transportsmedical and logistical aspects

    No full text
    The increasing establishment of medical centres of excellence prompted by economic pressures, has in the past resulted in notable changes in regional health care structures. This required the provision of interhospital transfer services capable of maintaining the intensive care needed by critical ill patients. The aim of this study was to analyse the data collected between 1999 and 2005 regarding a ground-based physician-manned interhospital transfer service at the university hospital of Mannheim. In addition to medical aspects, the study emphasises the logistical aspects of the system and its integration within the existing emergency medical services. In the period considered, the data of 2,082 patients were investigated. A breakdown of the patient's by organ system requiring the transfer of the patient, reveals the following picture: cardiovascular illness (41 %), illness or traumatisation of the central nervous system (37 %) and respiratory system (13 %). The average transportation distance was between 59 km (1999) and 34 km (2004), with an increase in the middle of the distance spectrum between 20 and 49 km being noted. 74 % of such transports were initiated by large general hospitals (LGH). In 54 % of the cases the destinations of the intensive care transfers were outlying facilities of the LGH, in 22 % hospitals for basic and standard care and in 13 % rehablitation facilities. The increasing volume of intensive transferscan be taken as proof of the acceptance and the increasing need for a ground-based intensive care transfer system in the Rhein-Neckar region. In comparison with the intensive care helicopters, the Mannheim transfer system also closes the gap in secondary transportation within the field of regional transfer and represents the most suitable solution even from the economic point of view within this setting

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We 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
