Roxas, San Vicente, Taugad Diit, Taugad Daka Forest 27.IX.2014, leg. C. V. Pangantihon (P513)”. The holotype will be deposited in the National Museum Manila, the paratype in the first author’s collection. Type locality: Philippines, Mindoro Island, Mindoro Oriental province, municipality of Roxas, barangay San Vicente, sitio Taugad Diit, Taugad Daka Forest, ca. 400–500 m a.s.l., ca. 12°38’ N, 121°20’ E. Diagnosis (worker): Predominantly black, moderately large species, TL = 4.8. Head with large punctures that are sparse dorsally, and relatively dense on genae and posterolaterally of eyes. Frontal carinae short, hardly exceeding antennal fossae; antennal scrobes absent. Clypeus dorsally without sculpture; ventral surface with small medial tooth; anterior margin with 7–8 small denticles medially and two pairs of blunt teeth laterally. Scape relatively short (SI = 95–97). Masticatory margin of mandible with four teeth and diastema. Dorsum of mesosoma smooth and polished. Pronotum with pair of short, but distinct teeth (PSL1 0.15–0.17), which are clearly shorter than propodeal spines (PSL2 0.26–0.28). Petiole stout, anterior face of node continuous with dorsal surface of peduncle. Both petiolar node and postpetiole with several setae of varying length. First gastral tergite without erect setae. Description: Measurements: holotype worker: TL 4.8, HL 1.27, HW 1.32, CI 104, SL 1.25, SI 95, EL 0.22, AL 1.21, PSL1 0.17, PSL2 0.28, PW 0.77, PPW 0.34, PPL 0.39, PPI 87. Paratype worker: TL 4.8, HL 1.29, HW 1.33, CI 103, SL 1.29, SI 97, EL 0.22, AL 1.21, PSL1 0.15, PSL2 0.26, PW 0.79, PPW 0.36, PPL 0.4, PPI 93.

Antennal scrobes and frontal lobes not developed; antennal insertion entirely exposed. Clypeus dorsally without median carina, ventrally with distinct central tooth; anterior margin with 7–8 small denticles in middle and two pairs of blunt teeth at sides. Labrum apically with pair of small tubercles. Mandibles (Fig. 2) smooth and shiny; masticatory margin of mandible with four teeth: strongest apical + second strongest (hardly shorter) preapical + long diastema + two small basal teeth of similar size; basal margin of mandible with slight dilatation at mid-length, but lacking distinct tooth. Palp formula 1, 3. Antennal scapes short, when lying on dorsum of head, slightly surpassing posterior margin of head. Eyes containing 11 ommatidia in longest row. Profile shape of mesosoma, petiole and postpetiole as in Figure 3. Dorsum of mesosoma slightly convex, smooth and polished except for a few scattered fine hair pits (Fig. 4). Pronotum with pair of relatively strong teeth; propodeum with pair of spines that are distinctly longer than pronotal teeth (Fig. 3). Mesopleural ridge almost straight, anteriorly not protruded into distinct tooth. Metapleural lobes subtriangular, acute. Petiole, postpetiole, and gaster smooth and shiny. Petiole in profile with moderately long peduncle, node without distinct angles. Postpetiole in profile rounded dorsally, in dorsal view broadening from front to back. Pilosity: Dorsal surfaces of head, mesosoma, petiolar node, and postpetiole with numerous, moderately long setae. First gastral tergite lacking erect or suberect setae. Clypeus with forward projecting setae between teeth and with four pairs of long setae at sides of medial part. Scapes and tibiae with numerous erect setae. Colour: Almost entirely black; clypeus, labrum, mandibles, antennae, and tarsi brown. Notes: Pristomyrmex pangantihoni sp. n. belongs to the P. quadridens group (sensu Wang 2003) and is similar and probably closely related to P. collinus Wang, 2003. The two species share most of the structural characteristics used in the key by Zettel (2006) and have similar surface structures. Another similar species is P. quadridens Emery, 1897. Whereas P. collinus is endemic to the northern and central Philippines (records from Luzon, Tablas, Panay, and Negros), P. quadridens is distributed on New Guinea and the Moluccas and reaches the Philippines in the southeast (Leyte) (Wang 2003, Zettel 2006). Pristomyrmex pangantihoni sp. n. differs from both species by black colour, longer pronotal and propodeal spines, higher number of setae on both petiole and postpetiole, and much larger size (measure- ments partly taken from Wang 2003 and Zettel 2006): TL of P. pangantihoni sp. n. 4.8 mm, of P. collinus and P. quadridens 3.3–4.1 mm; HW of P. pangantihoni sp. n. 1.32–1.33 mm, of P. collinus and P. quadridens 0.77–0.94 mm. The puncturation on the head of P. pangantihoni sp. n. is more strongly developed than in P. collinus, but not as foveolate as in P. quadridens. Also the shape of the petiole is intermediate between the two species. Pristomyrmex distinguendus Zettel, 2006, another similar species of Luzon and Leyte, can be distinguished by brown colour, small size, long frontal carinae, distinct antennal scrobes, and very short pronotal and propodeal teeth. Pristomyrmex pangantihoni sp. n. is the second species recorded from Mindoro. Wang (2003) recorded P. punctatus from San José in Occidental Mindoro Province; this species has a wide distribution from China to New Guinea.Published as part of Herbert Zettel & Alice Laciny, 2015, A new species of Pristomyrmex Mayr, 1866 (Hymenoptera: Formicidae) from Mindoro, the Philippines, pp. 1-4 in Asian Myrmecology 7 on pages 2-
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
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
