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
Phenology of two Acanthophora najadiformis (Rhodophyta, Ceramiales) populations in the Ionian Sea (Mediterranean Sea)
No full textBoth an intertidal and a subtidal population of Acanthophora najadiformis near the Cheradi Islands (Ionian Sea, Mediterranean Sea) were studied in order to know the life cycle of the species and both seasonal variation in plant size and the phenology of reproduction. The proportions of gametophytes, tetrasporophytes and propagule-bearing plants were analysed. Acanthophora najadiformis proved to be a perennial alga present only with the overwintering basal system in winter and spring and well developed fronds in summer and autumn, when it is the dominant species in the subtidal community. Differences in both plant size and reproductive plant number were detected between the intertidal and subtidal levels. In the intertidal zone plants grow faster and reach greater sizes than the subtidal ones; tetrasporophytes and propagule-bearing plants are more numerous than at the subtidal level. In both zones, tetrasporophytes seem to be dominant and propagule-bearing plants are by far the most numerous

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
