Pseudolechriops Champion 1906
No full textPseudolechriops Champion, 1906: 60 Type: P. megacephala Champion, by monotypy. Champion cited the “broad head, the somewhat widely separated eyes, the almost straight, flattened rostrum, [and] the short, subcylindrical prothorax” as distinctive. Champion compared his new genus with the genera Tachylechriops Heller and Lechriops Schoenherr, although it is probably not closely related to either genus. The legs of Pseudolechriops species are proportionately much longer and more slender than those of most Lechriops, but we have seen South American specimens that appear to be intermediate between the two genera. The genus Tachylechriops has the posterior legs disproportionately enlarged and the posterior tibiae broadly, laterally flattened and arcuately rounded on the posterior margins, a trait that occurs in several unrelated conoderine genera (Zygops Schoenherr, Paramnemyne Champion, Macrolechriops Heller, etc.) and in Tachygonus Schoenherr. It is found in a less extreme form in the part of the genus Pseudolechriops that includes P. megacephala, but not uniformly throughout the genus. The relationships of Pseudolechriops will have to wait for a more general review of New World conoderine genera and subfamilies. As interpreted here there are two relatively well defined species groups. In the group that includes P. megacephala (the megacephala group), species are basically black in coloration, rhomboidal in body form, posterior tibiae are laterally flattened and more or less arcuately rounded on the posterior margins, and males have the rostrum more or less strikingly modified. Species in the second group (the coleyae n.sp. group), are usually reddish brown in coloration, more slender in form, have subcylindrical posterior tibiae, and rostra of males are not or only slightly modified. The two groups are different enough that they might be considered different genera, but all share similar larval biologies and are united by P. klopferi n.sp. which shares some characters of both groups. In addition to the differences between the two species groups, species are distinguished primarily by setal patterns, coloration of the legs (the coleyae group), and structure of the male rostrum (especially in the megacephala group). Male genitalia are not very distinctive at the species level, but differences in the male rostra and in the setal coloration of the anterior and middle legs of males suggest the existence and importance of male-male interactions or male courtship behavior that usually accompanies secondary sexual characteristics. Sexes of all but one of the species treated here can be separated externally. Although not yet observed in Pseudolechriops, male-male interactions have been described for other conoderine weevils (Lyal 1986).Published as part of Hespenheide, Henry A. & Lapierre, Louis M., 2006, A review of Pseudolechriops Champion (Coleoptera: Curculionidae: Conoderinae), pp. 1-39 in Zootaxa 1384 on page 3, DOI: 10.5281/zenodo.17506
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
Pseudolechriops alleni Hespenheide & LaPierre, new species
No full text8. Pseudolechriops alleni Hespenheide & LaPierre, new species Fig. 8, a–d Diagnosis: Black except tip of rostrum, tarsi, anterior and middle legs and basal ½ of posterior femora and apical ½ of posterior tibiae reddish brown; posterior tibiae slender, subcylindrical, not conspicuously flattened; from above slender, subcylindrical, with elytra not conspicuously wider than base of pronotum; setae on sides of pronotum sparse, irregularly distributed over most of surface; elytra with conspicuous transverse white fascia at base connected to weak sutural spot beyond middle; male with eyes more widely separated, males densely white setose at base of rostrum above antennal insertions; Costa Rica. Description: Holotype male: Black, except apex of rostrum, antennae, base of hind femora and apex of hind tibiae, tarsi, anterior and middle legs reddish brown; from above (Fig. 8 a), setae mostly hair like and white, elytra with transverse band of setae at bases of elytral intervals extending anterior to humeri to lateral margins, setae extending along intervals 1–2 to beyond middle, more conspicuous in a vague white spot beyond middle; pronotum with hair like setae, transparent and inconspicuous from above, except at sides with indistinct area of white setae; head glabrous above, front with dense white setae between eyes and extending on rostrum to antennal insertions; beneath and on sides moderately densely and uniformly covered with white setae, denser on epimera, sparser on middle of abdominal sternite 1 and on sternite 5; external faces of anterior and middle femora rather densely covered with fine white setae, setae somewhat sparser on posterior femora and tibiae; 2.6 mm long. Head prominent, about 3 / 4 as long as pronotum, dorsally finely punctate, with medial carina, eyes arcuately rounded, as wide as pronotum at apex; from front (Fig. 8 c), eyes rather widely separated for almost their entire length with shallow linear depression along midline, rostrum expanding basally with antennae inserted at middle, narrow and polished distal to antennal insertions, carinate along midline above antennal insertions, from side nearly straight. Pronotum from above nearly conical, base 1 / 3 wider than apex, from lateral view nearly flat, disc somewhat coarsely punctate, with fine medial carina and small glabrous spot along midline just before middle. Elytra together about 1 / 4 broader than pronotum, widest behind humeri, 1 / 3 longer than wide, lateral margins very weakly arcuate, narrowing only slightly to near apices, apices broadly, separately rounded. Mesosternum with well-defined groove with low ridges to receive rostrum continuing to excavate and carinate anterior margin of metasternum; metasternum narrowly incised along midline to abdomen. Abdomen with first and anterior 1 / 2 of second ventral sternite weakly depressed along midline; sternite 5 convex. Femora unarmed, posterior femora with very fine carina only at basal 1 / 4; posterior tibiae terete (Fig. 8 b). Holotype male: Costa Rica: Heredia Pr., Est. Biol. La Selva., 50–150 m, INBio-OET, 10 o 26 ’ N 84 o 01’ W, 0 9.05. 2002, L.M. LaPierre, ex Cecropia insignis, ID #: (INBC). Paratype: Same data as Holotype, except 10.1997, and “see records Cins 97.28 ” (CHAH). Etymology: Named in honor of Robert L. Allen, nature photographer, author and biology professor in California, who encouraged LaPierre’s interest in insects during high school. Discussion: The aedeagus of the teneral paratype is pale transparent brown, darker in the middle 1 / 3, and is illustrated in Figure 8 d, and the paratype is 2.7 mm long. Pseudolechriops alleni resembles P. janeae in having conspicuous white setae on the front and in the pattern of white setae on the elytra, but it is black rather than brown and the setae on the lateral portions of the pronotum are not condensed into a well-defined oblique stripe. This species has been reared from live petioles of juvenile Cecropia (see Table 1 and the Discussion section for more detailed information).Published as part of Hespenheide, Henry A. & Lapierre, Louis M., 2006, A review of Pseudolechriops Champion (Coleoptera: Curculionidae: Conoderinae), pp. 1-39 in Zootaxa 1384 on pages 24-26, DOI: 10.5281/zenodo.17506
