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
T-Wave Alternans Quantification: Which Information from Different Methods?
No full textT-wave alternans, qualitatively defined as every-otherbeat alternations of the T-wave morphology, has no standardized quantitative definition yet. Differences in quantitative information provided by the fast-Fouriertransform spectral method (FFTSM), the modifiedmoving- average method (MMAM), and our heart-rate adaptive match filter method (AMFM) were analyzed here making use of two synthetic ECG tracings with stationary TWA: triangular the first (TRI_TWA), with Twaves maximum-amplitude difference (AMAX) of 100 mu V and mean-amplitude difference (AMEAN) of 50 mu V; and uniform the second (UNI_TWA), with A(MAX)= A(MEAN)= 100 mu V. Application of FFTSM, MMAM, and AMFM to TRI_TWA yielded 57 mu V, 100 mu V, and 50 mu V TWA amplitude estimation, respectively. Instead, 100 mu V TWA amplitude was provided by each method after their application to UNI_TWA. Thus, FFTSM and AMFM provide estimates of AMEAN, while MMAM of AMAX
