    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

    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

    Clinical study on 15 cases of torsion of the spermatic cord

    過去10年間の15例は10~40, 平均21.1歳であった.右停留精巣の1例以外は全て左側に発生した.発症時刻が判明している13例中12例で睡眠中及び起床後1時間以内に発症していた.停留精巣1例以外の全例が精巣痛を訴え, 少数は鼠径部及び下腹部の疼痛を伴っていた.大多数で精巣の腫脹・圧痛が認められ, 精索の短縮は捻転及び2次的炎症によると思われ, 重要な所見であった.Prehn徴候及び発熱は数例にみられたが, 白血球数増加は10例に認められた.手術11例中10例で精巣固定術, 1例で精巣摘除術を行った.4例は自然整復例と判断された.健側の精巣固定は行わなかったが, 再発はみていないWe experienced fifteen cases of torsion of the spermatic cord during the past 10 years. The age distribution was from 10 to 40 years old and the average age was 21.1 years. All cases except one case of right undescended testis occurred on the left side. To our interest, the onset in 12 of the 13 cases with known onset time were during sleep or within one hour after waking up. All cases except one case in the undescended testis complained of pain of the testis and some of them were accompanied with pain in the inguinal and lower abdominal region. Swelling and tenderness of the testis were observed in most cases and shortness of the spermatic cord probably caused by torsion and secondary inflammation seemed to be important findings. Prehn's sign and fever up were observed in few cases but leukocytosis was seen in 10 cases. Eleven cases of surgical treatment consisting of 10 orchiopexy and one orchiectomy were performed. Four cases of spontaneous detorsion were included in our experience. Orchiopexy of the contralateral intact testis was not done, but, we have never experienced relapse of torsion
