    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

    Muscle Strength of Upper Extremities and Trunk in Collegiate Throwing Players

         The overhead throwing, a complex movement skill used in sports, involved the series of linked movement of the body from legs through arm and hand with rotating each body segment to transfer velocity, momentum and energy in sequence such as tennis and volleyball serves, baseball pitching, javelin throw. The objectives of this study were to compare the strength of the upper extremities muscles of collegiate overhead throwing players, and healthy students who did not participate in these sports. The muscle strength of the dominant and non-dominant sides of the participants were included in the analysis and comparison. Sixty participants were divided into two groups; an experimental group consisted of 15 male players (age 20.47+1.19 years, bodyweight 69.57+8.25 kg, and height 168.47+24.73 cm) and 15 female players (age 19.87+0.99 years, bodyweight 61.20+12.16 kg, and height 162.27+5.28 cm). The other group was control group, consisted of 15 male non-players (average age 20.60+1.12 years, bodyweight 70.51+12.30 kg, and height 174.33+5.65 cm) and 15 female non-players (age 20.07+0.70 years, bodyweight 54.47+6.59 kg, and height 162.67+6.39 cm). Participants were tested and measured by the Upper Quarter Y-Balance test, in which the participants bore a weight on the testing arm at the center and reached in various directions. Paired and independent t-tests were used for comparing the differences of average composite scores between dominant and non-dominant, and between control and experimental groups respectively. The significant level was set at .05 (p < .05). The results revealed that there was no difference of the composite scores between dominant and non-dominant arms in all participants but there were significant differences of the composite scores on the dominant arm (p = .05) and non-dominant arm (p = 0.02) when comparing between control and experimental groups. It was concluded that there was no significant difference of the muscle strength of upper extremities and trunk, both dominant and non-dominant sides but the muscle strength of upper extremities and trunk of the overhead throwing players was lower than of the regular exercise group. It could be feedback information for coaches and players to improve training plans, skill development and injury risk reduction.

    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

    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
