Variations on the Author
No full text“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
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

On the Bennelongia barangaroo lineage (Crustacea, Ostracoda) in Western Australia, with the description of seven new species
No full textThe ostracod genus Bennelongia De Deckker & McKenzie, 1981 is endemic to Australia and New Zealand. Extensive sampling in Western Australia (WA) revealed a high specific and largely undescribed diversity. Here, we describe seven new species belonging to the B. barangaroo lineage: B. timmsi sp. nov., B. gnamma sp. nov., B. hirsuta sp. nov., B. ivanae sp. nov., B. mcraeae sp. nov., B. scanloni sp. nov. and B. calei sp. nov., and confirm the presence of an additional species, B. dedeckkeri, in WA. For five of these eight species, we could construct molecular phylogenies and parsimonious networks based on COI sequences. We also tested for cryptic diversity and specific status of clusters with a statistical method based on the evolutionary genetic species concept, namely Birky’s 4 theta rule. The analyses support the existence of these five species and a further three cryptic species in the WA B. barangaroo lineage. The molecular evidence was particularly relevant because most species described herein have very similar morphologies and can be distinguished from each other only by the shape, size and position of the antero-ventral lapel on the right valve, and, in sexual populations, by the small differences in shape of the hemipenes and the prehensile palps in males. Four species of the WA B. barangaroo lineage occur in small temporary rock pools (gnammas) on rocky outcrops. The other four species are mainly found in soft bottomed seasonal water bodies. One of the latter species, B. scanloni sp. nov., occurs in both claypans and deeper rock pools (pit gnammas). All species, except for B. dedeckkeri, originally described from Queensland, have quite clearly delimited distributions in WA. With the seven new species described here, the genus Bennelongia now comprises 25 nominal species but several more await formal description
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Timms on 01 Aug. 2010 (11 ♂♂ and ♀♀, WAMC 52253-52262; OC.332-3321). Differential diagnosis Bennelongia timmsi sp. nov. can be distinguished from most species of the B. barangaroo lineage by the triangular and ventrally pointed lapel on the RV and the strongly sinuous ventral valve margins. The lapel of B. scanloni sp. nov. is also subtriangular and ventrally protruding, but it is rounded, thus looking drop-shaped in internal (non-tilted) view. Bennelongia timmsi sp. nov. can moreover be distinguished from B. gnamma sp. nov. by the less high and less rounded valves and by the ls of the hemipenes, which protrudes well beyond the ms (subequal in B. gnamma sp. nov.). Additional notes on cryptic species As was described above, five genetic clusters are recognised in this species (A1-5, Fig. 2). According to the calculations of the 4 theta rule, three cryptic species were found in B. timmsi sp. nov. with molecular methods, but no morphological diagnostic features could be found. Cryptic species A1 occurred in BVT/10/02, 03 and 07. Cryptic species A3 was found in BVT/10/02, 04, 06 and 08. Cryptic species A2+A4+A5 occurred in BVT/10/03 and 05 and is used here to characterize B. timmsi sp. nov. with BVT/10/05 (Wave Rock) as type locality. Note that BVT/10/02 (Grahams Rock) and BVT/10/03 (Anderson Rock) hold at least two sympatric clades/cryptic species each. In order to establish beyond reasonable doubt that the specimens belonging to these clusters and cryptic species are indeed morphologically indistinguishable, long series of specimens are illustrated. Sample BVT/10/05 from pools on Wave Rock appeared to contain only one genetic cluster and cryptic species and, for this reason, Wave Rock was chosen as type locality. We then proceeded with two different approaches: (1) to dissect a series of males from this sample to test whether male reproductive organs (hemipenes, prehensile palps) showed uniformity within one cluster/cryptic species; (2) we checked for potential differences in the morphology of the valves of specimens belonging to different populations and/or shown to belong to different clusters/cryptic species. Type specimens Valves and carapaces of males and females of the type population (in sample BVT /10/05) were illustrated (Fig. 4) and this morphology defines the species. We then dissected several males from the same sample and population and illustrated the soft part and valve morphology. Shape of valves and size and shape of the antero-ventral lapel on the RV were most similar and indeed almost indistinguishable (Fig. 5). In all male specimens the valves have the shape described in the diagnosis above. The lapels are all elongated subtriangular, with a more or less serrated distal margin. In tilted perspective some lapels appear to be shorter than others (e.g., the lapel in Fig. 5B appears shorter than in 5E), but this is almost entirely a matter of distorted perspective depending on how the valves were positioned when the photographs were taken (the same lapels appear almost equally long in non-tilted views - Fig. 5A and 5F, respectively). However, there are significant differences in soft part morphology. Whereas the shapes of the hemipenisoutline and of the left prehensile palps are fairly uniform in the different specimens (Figs 8A, C, E-F; 9A, C-D, F), the second segment of the right prehensile palps ranges from elongated sub-triangular with almost equally rounded distal margin (Fig. 8B, D), to sub-rectangular with a clear blunt corner in this margin (Fig. 9B, E). It is not clear to what extend these differences are a biological reality, or whether the differences are distortions of the limbs caused by different positions in the slides. The differences are sufficiently small to be accepted as part of intra-specific variability, yet future investigations should take this variability into account. The morphology in the holotype (WAMC 52228 – right prehensile palp in Fig. 8D) determines the specific morphology. One male (WAMC 52232 – Fig. 10 A-D) had an aberrant morphology, with the terminal segment of the right prehensile palp (Fig. 10D) being even more elongated and with especially the terminal segment of the left prehensile palp being distally bilobed (Fig. 10C, C ”), a morphology never before encountered in Cyprididae. Nevertheless the valves of this male show no differences with other type specimens (Fig. 5 A-C). Morphology within different clades/cryptic species Valve morphology of specimens for which molecular clades are known (A1: Fig. 6 A-C; A2: Fig. 6 D- I; A3: Fig. 6 J-L; A5: Fig. 6 M-O, 7A-C) and for specimens from different populations for which no molecular data were available (Fig. 7 D-N) again show no constant differences that could be used as identifying characters. There is some variability in size, shape and degree of crenulation of the lapel, but insufficiently so to use such features to characterise different clades/cryptic species. One male specimen from BVT /10/02 and thus belonging to either cryptic species A1 or A3, had a right prehensile palp with a terminal segment clearly showing a blunt angle on the distal margin (Fig. 11C), while a male from BVT /10/06, and thus most likely belonging to clade A2, had a more elongated segment there with a more rounded distal margin (Fig. 11G) as in the holotype. In both of these specimens, the terminal segment of the left prehensile palp is slightly shorter than in the type specimens (Fig. 11D, F). Hemipenis outlines (Fig. 11 A-B, E) are indistinguishable from those in the types. Ecology and distribution Bennelongia timmsi sp. nov. is a typical rock pool species and occurs in fresh water in gnammas on various rocky outcrops in the south/central part of western Australia. Although it appears to be limited to this restricted area, it seems to be quite common there.Published as part of Martens, Koen, Halse, Stuart & Schön, Isa, 2013, On the Bennelongia barangaroo lineage (Crustacea, Ostracoda) in Western Australia, with the description of seven new species, pp. 1-59 in European Journal of Taxonomy 66 on pages 17-27, DOI: 10.5852/ejt.2013.66, http://zenodo.org/record/382759
Nine new species of Bennelongia De Deckker & McKenzie, 1981 (Crustacea, Ostracoda) from Western Australia, with the description of a new subfamily
No full textThe genus Bennelongia De Deckker & McKenzie, 1981 is most likely endemic to Australia and New Zealand and, up to now, only two described species in this genus had been reported from Western Australia. Extensive sampling in Western Australia revealed a much higher specifi c diversity. Here, we describe nine new species in three lineages, within the genus Bennelongia: B. cygnus sp. nov. and B. frumenta sp. nov. in the B. cygnus lineage, B. gwelupensis sp. nov., B. coondinerensis sp. nov., B. cuensis sp. nov., B. lata sp. nov. and B. bidgelangensis sp. nov. in the B. australis lineage, and B. strellyensis sp. nov. and B. kimberleyensis sp. nov. (from the Pilbara and Kimberley regions respectively) in the B. pinpi-lineage. For six of the nine species, we were also able to construct molecular phylogenies and to test for cryptic diversity with two different methods based on the evolutionary genetic species concept, namely Birky’s 4 x rule and the GYMC model. These analyses support the specifi c nature of at least four of the fi ve new species in the B. australis lineage and of the two new species in the B. pinpi lineage. We also describe Bennelongiinae n.subfam. to accommodate the genus. With the nine new species described here, the genus Bennelongia now comprises 15 species, but several more await formal description
