The shallow water hard corals of Pulau Weh, Aceh, Indonesia
Full text linkThe corals reefs of Aceh, Indonesia, are one of the few areas of the world where the fauna, in particular the scleractinian corals, have yet to be described. The area is likely to be of high biogeographical significance due to its position at the northern tip of Sumatra on the boundary of three major water bodies, the Indian Ocean, the Andaman Sea and the Straits of Malacca. Here, we present the quantitative description of the assemblage structure of the shallow water scleractinian corals of Pulau Weh. Carbonate reefs are rare on the island, the exception being some fringing reef development in shallow water in at least two locations. Most colonies are attached to granite boulders which make up the ocean floor at most sites on the north and west coast, or rest in the sandy substrates that dominate the ocean floor on the east coast. Coral cover in February 2009 was over 40 % at most sites, ranging from 21 % ± 3.0 SE to 80 % ± 2.4. Coral assemblage structure varied widely around Pulau Weh with assemblages from the western and northern sites being dominated by Acropora spp. in particular, species with digitate, encrusting-arborescent and tabular morphologies. In contrast, coral assemblages on the west coast were dominated by massive Porites spp. and Heliopora. The Acropora fauna is dominated by species with digitate and encrusting arborescent morphologies; very different from many other regions in Indonesia. This unusual species composition plus the presence of a high proportion of endemics indicates that the region should be a high priority for conservation efforts. Further taxonomic studies at depth and further afield are required to fully describe this unique fauna that supports a small diving industry and a number of fisheries
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
