Monopodial percurrent branching. Stem internodes persistently keeled, 2.3–6.5 cm long, 3.3–5.3 mm diameter in keeled portion, 2.5–4.1 mm diameter in flattened portion; first branching internode 3.6–5.4 cm long, being the same shape as stems, basal cataphylls (2–)3(–5) pairs, basally fused and distally separate, last pair borne up to 1–2.5 cm above the branch base, intercalary cataphylls absent. Leaves 10–19 × 2.5–5 cm, coriaceous, lanceolate, subsessile, apex acute and distally rounded, base tapering to a winged indistinct petiole. Venation palmate, 4–6 lateral arched veins ascending towards leaf apex, midvein conspicuously raised abaxially. Dioecious. Staminate inflorescences usually 1 per axil, 1.5–3 cm long; peduncles compound with 0‒4 pairs of sterile bracts; up to 7 fertile internodes, cylindric, triseriate, 1.5–4 × 2–3 mm, flowers 3–13 per fertile bract, embedded in a glabrous foveae, ca. 1 mm diameter, stamens epipetalous, sessile, bilocular anthers, with a papillose rudiment in the middle of the petal. Pistillate inflorescences usually 3 per axil, 2.5–3.5 cm long; peduncles simple; fertile internodes 5–6, swollen with a spherical appearance, flowering internodes 2.5–5 × 3–3.8 mm, fruiting internodes 5.8–7.0 × 5–7.8 mm; triseriate; flowers (1–)5–9 per fertile bract, 3(–4)-merous, ca. 1 mm diameter, almost completely embedded in the foveae, with a papillate crown. Fruit a yellow one-seeded berry, ca. 3 × 3 mm (dehydrated), with a smooth surface; remnant perianth closed. Additional specimens examined: — COLOMBIA. Dpto. Huila: Mun.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
