No full textGenus Astreopora De Blainville, 1830 Colony massive, encrusting, plating or ramose. Axial corallite rarely present. Columella absent, but pseudo-columella, formed by trabecular extensions of the septa, may be present. Coenosteum reticular, formed by outwardly inclined trabeculae, with spinose surface. Dissepiments tabular. Occurrence: Upper Cretaceous to Recent; Europe, Caribbean and Indo-Pacific.Published as part of Wallace, Carden C., Turak, Emre & DeVantier, Lyndon, 2011, Novel characters in a conservative coral genus: three new species of Astreopora (Scleractinia: Acroporidae) from West Papua, pp. 1905-1924 in Journal of Natural History 45 (31 - 32) on page 1909, DOI: 10.1080/00222933.2011.573098, http://zenodo.org/record/465244
Acroporidae Verrill 1901
No full textFamily ACROPORIDAE Verrill, 1901 Massive or ramose colonies by extratentacular budding; corallites small, synapticulothecate, pseudo-costate, slightly differentiated from coenosteum. Septa non-exert, in two cycles, formed by simple spiniform trabeculae projecting inward and upward from vertical mural trabeculae, commonly fusing to form laminae. Columella absent or trabecular and weak. Dissepiments thin and tabular when developed. Coenosteum extensive, light reticulate, flaky, generally spinose or striate on surface. Polyps hermaphrodite with internal or external fertilization followed by internal or external larval development respectively. Occurrence: Upper Cretaceous to Recent.Published as part of Wallace, Carden C., Turak, Emre & DeVantier, Lyndon, 2011, Novel characters in a conservative coral genus: three new species of Astreopora (Scleractinia: Acroporidae) from West Papua, pp. 1905-1924 in Journal of Natural History 45 (31 - 32) on page 1909, DOI: 10.1080/00222933.2011.573098, http://zenodo.org/record/465244

No full textFIGURE 2. Corallite budding and new branch formation in Euphyllia baliensis sp. nov. a—Corallite elongates and two opposing primary septa on the narrow axis begin to fuse. b—The corallite begins to pinch along the long axis and the upper wall begins to overgrow along the middle of the short axis. c—Walls on the opposing ends fuse forming two daughter corallites. d—Corallites grow apart. e—New independent corallites form new branches. f—Rarely a triple division may occur, which leads to triple branching. Scale—all images 1cm wide. Photos by E. Turak.Published as part of Turak, Emre, Devantier, Lyndon & Erdmann, Mark, 2012, Euphyllia baliensis sp. nov.

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
