    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

    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

    Quality of life and sexual satisfaction in women suffering from endometriosis: an Italian preliminary study

    No full text
    Endometriosis is a chronic gynaecological disease that affects women during the reproductive age, and may compromise their quality of life (QoL) and sexual satisfaction. Few data are available on women affected by pelvic endometriosis in the absence of deep infiltrating endometriosis. Aim of the study To evaluate QoL and sexual satisfaction in a group of Italian women affected by pelvic endometriosis identifying specific sociodemographic variables that could impact on the individual perception of the disease. Method A survey was conducted on 150 women with pelvic endometriosis, recruited at the University hospital of Rome. The control group included 150 healthy women matched for age and relational status. A sociodemographic questionnaire, the Italian versions of the WHOQOL-Bref and McCoy Female Sexuality Questionnaire (MFSQ) and the Visual Analogue Scale were administered to participants. Results Our data show that the experimental group obtained a lower score than the control group in the questionnaire total scores and, specifically, in the physical, psychological and social relationships domains (WHOQOL) and in the sexuality domain (MFSQ). A positive and significant correlation was observed between relational status and the MSFQ total score. No significant correlation emerged between pain intensity and sociodemographic variables, total scores and subscales of the MSFQ and WHOQOL-BREF. Discussion and conclusion Our results showed that the disease has a negative impact on many areas of the overall functioning and sexuality quality of life of women. Nevertheless, the existence of mediatory variables emerged, emphasising how the presence of a partner could be considered a protective value in the experience of pain, therefore stressing the need to adopt a bio-psychosocial perspective to study and fully understand the disease
