No full textPhaneroptera rentzi sp. nov. Fig. 1—a, i, j, o; Fig.2 —A–N, Diagnostic characters: Male ( ♂ ). Body yellowish green. Fastigium vertices scapus wider, apically narrow with obtuse, a fine median sulcus (Fig. 2C), strong pigmentation on the dorsal side of fastigium as well as the entire pronotum (Fig. 2B, D); anterior margin of pronotum flat, posteriorly concave; tegmen surpassing the hind wing, dorsally flat, clear wing venation, cerci of male strongly bent inward behind the sub genital plate (Fig. 2K), apex of cercus strongly acute with short and stout black spine (Fig. 2M and Fig. 1a), subgenital plate strongly bifurcate, incurved (Fig. 2 J and Fig. 1j). Colouration. Yellowish green colour. Female. Unknown. Type Material. Holotype: ♂, Dharmapuri (N 0 12007 ’11.21’’E 077051 ’.01.94’’), Tamilnadu, India. 11 II 2018. Coll. G. Divya and N. Senthilkumar. Deposited in Gass Forest Museum (GFM), Institute of Forest Genetics and Tree Breeding, Coimbatore, Tamilnadu (India). Distribution. Dharmapuri, Tamilnadu, India. Etymology. This species is named in honour of Dr D. C. F. Rentz, Australia. Discussion. The new species is completely differs from P. spinosa, P. myllocerca, P. falcata and P. gracilis on the structure of subgenital plate, supra anal plate, pronotum and fastigium vertices. P. rentzi, sp. nov. is entirely differ from the P. spinosa, P. myllocerca and P. falcata by the shape of cerci and subgenital plate. P. gracilis and P. rentzi, sp. nov. are look-alike however, the subgenital plate is entirely different (Fig. 1j, m). The lateral lobe of pronotum deeper than long, without white band; fairly and smoothly rounded not forming angle with disc, sharp emargination at posterior end of insertion. Subgenital plate bilobate at the apex. Distal lobe of subgenital plate not smoothly rounded but pointed. Apex of the cerci abruptly bent inwards. Stridulatory vein large almost as wide as left tegmen; distal end of file as in Fig. 2 E.Published as part of Divya, Govindaraj & Senthilkumar, Natchiappan, 2020, Contribution to the knowledge of the genus Phaneroptera (Tettigoniidae Phaneropterinae) with a new record from Tamilnadu, India, pp. 425-434 in Zootaxa 4860 (3) on page 426, DOI: 10.11646/zootaxa.4860.3.7, http://zenodo.org/record/441406

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
A Collaboration-Enabling Framework For Java Beans
No full textOF THE THESIS A Collaboration-Enabling Framework for Java Beans by Senthilkumar Sundaram Thesis Director: Professor Ivan Marsi'c Most of the existing collaborative applications are collaboration aware, i.e., collaboration semantics are interleaved into application semantics. This thesis contributes: ffl A generic collaboration bus to which any (including single-user) applications can be plugged in as is and made collaborative without any modification to the application or to the collaboration bus. This collaboration framework eliminates several drawbacks suffered by the existing "generic frameworks." ffl A set of guidelines and methods for writing wrappers around the single-user applications in order to make them collaboration aware so they can take advantage of the cooperative features of the bus. ffl Design guidelines for developing special purpose applications to be aware of the proposed bus and to enable them to manage the cooperative features of the bus effectively.

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

Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
