Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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

Some new aspects of the functional anatomy of the shoulder.
No full textThe authors investigated the functional role of the shoulder muscles in various active movements using simultaneous polymyographic recordings. Ten muscles were investigated in both normal subjects and in patients with pathological conditions. Ten patients were also studied during the course of operations for nonrelated conditions by "tetanizing" stimulation of nerves to individual muscles to determine their action as single muscles
Transplant of the teres major in the treatment of irreparable injuries of the rotator cuff (long-term analysis of results).
No full textPurpose of this study is to evaluate the effectiveness of muscle transfer of the teres major in the treatment of irreparable posterosuperior injuries of the rotator cuff. Long-term monitoring of the results obtained in 20 patients treated at our clinic using this method are reported, comparing the data obtained in evaluations of results with preoperative values. Clinical evaluations were obtained using the Constant Score System, while X-ray examination showed the presence of osteoarticular modifications, and MRI and electromyography the preserved morphology and function of transplant. The mean Constant Score increased from 31.6 points preoperatively to 66.1 points postoperatively at the time of follow-up. At follow-up, MRI allowed us to evaluate any fatty degeneration of the muscle fibers of transfer and the integrity of tendinous insertion on the humeral greater tuberosity. The obtained results allowed us to reveal the advantages and the disadvantages of teres major transplant in irreparable posterosuperior ruptures of the cuff
