Going Beyond Counting First Authors in Author Co-citation Analysis
The 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

Dispelling the Myths Behind First-author Citation Counts
We 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
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
This work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country

Eumops chiribaya Medina, Gregorin, Zeballos, Zamora & Moras, 2014, sp. nov.
Eumops chiribaya, sp. nov. Chiribaya's Bonneted Bat Figure 4 Holotype. Dried skin, skull, and partial skeleton of an adult female (MUSA 8493), deposited at the Museo de Historia Natural de la Universidad Nacional de San Agustín (MUSA). The specimen was captured on 1 June 2010 by a local person and was taken to the MUSA, where it was received and prepared by Hugo T. Zamora (original number HZM 670). Tissues are deposited at MUSA. The specimen is in good condition, except by the broken lower left canine. Type locality. El Algarrobal, 111 m; 8.4 km NE of Ilo; Ilo Province; Moquegua Department; Peru, 17 º 37 ' 21.6 " S, 71 º 16 '06.6" W (Fig. 3). Etymology. The specific epithet chiribaya is given in honor of the Chiribaya culture (900–1,350 A.D.). Chiribayans were settled in the basin of the Ilo River, and expanded north to the Tambo valley (Arequipa) and the south to the Azapa valley (Chile), including the high altitude regions, up to nearly 3,000 m of elevation. Distribution. Eumops chiribaya is known only from the type locality (Fig. 3). Diagnosis. Eumops chiribaya is distinguished from all other species of the genus by the following combination of characters: medium body size; relatively large ears (25.7 mm); dorsal coloration light olive-brown, with slightly lighter belly; dorsal hairs bicolored, with white base that conspicuously contrast with the tip; square-shaped tragus; cranium with elongated rostrum; narrow post-orbital constriction; tiny incisive foramen; basisphenoid pits rectangular, deep and separated by a narrow septum; opisthocranion curved dorsally and anteriorly; mastoid foramen present; premetacrista equal to half the length of postparacrista on M 3; mandible gracile with a welldeveloped keel (Fig. 4). Description. Eumops chiribaya is a medium size species (Table 5). Dorsal coloration is light olive-brown, with a lighter belly. Pelage is soft, long (6 mm taken at the level of the shoulder region) with bicolored dorsal hairs (basal third of each hair white in color). Face naked; upper lip smooth to weakly wrinkled on distal edge of snout. Nose blackish; upper border of narial region surrounded by small and pointed warts, internarial ribs covered by small, spoon-like and blackish hairs. Ears large (25.7 mm), round, blackish and joined on the forehead; upper border smooth, but the inner face with brown hairs distributed from the dermal keel to the top of the ear. Tragus square-shaped. Antitragus semicircular, wider than higher. Dorsal surface of propatagium and plagiopatagium near to forearm and dactilopatagium at basal middle of fifth metacarpal covered with short light olive-brown hairs. Feet blackish; external edges and ventral surface of the first and fifth toes of the feet covered by short hairs, silver in color, with claws covered by longer hairs of the same color. Calcar longer than feet. Uropatagium dull brown with free portion of the tail blackish. Skull with elongated and narrow rostrum in dorsal view, and straight in profile (Fig. 4). Braincase rounded, tending to be angular anteriorly; opisthocranion curved dorsally and anteriorly. Nasal process of the premaxilla well-developed. Postorbital constriction narrow. Medial sagittal crest poorly developed. Palate long and slightly wide. Medial process of posterior margin of palate bridge absent. Incisive foramina tiny, with two concentric cusps longitudinally. Mesopterygoid fossa broad and rectangular. Foramen ovale well-developed. Sphenorbital fissure narrow. Basisphenoid pits large, deep, rectangle-shaped, and separated from each other by a narrow septum. Mastoid foramen present. Premetacrista equal to half the length of postparacrista on M 3. Mandible gracile with well-developed keel. Measurements of the holotype. The external measurements (mm) and weight (g) are: total length 134; tail length 52; hindfoot length 13.5; ear length 25.7; forearm length 61.1; and weight 20.3. Measures used in the morphometric analysis are indicated in table 5. Comparisons. Eumops chiribaya is a medium-sized member of Eumops (Table 5) phylogenetically related to medium-large sized species and morphologically more similar to E. perotis and E. trumbulli (Fig. 1). The smaller size distinguishes E. chiribaya from the large species E. perotis and E. trumbulli, also E. dabbenei and E. underwoodi (FA greater than 68 mm; Eger 1977). Eumops bonariensis, E. patagonicus, E. nanus, and E. hansae (here, E. bonariensis clade) are comparatively small (FA less than 49 mm; Table 1, Eger 1977) and differentiated in morphology and molecular data (Fig. 1). E. chiribaya is also distinguished from E. bonariensis and its relatives by smooth upper lips (finely wrinkled in E. bonariensis clade), blackish pelage (light or grayish brown in E. bonariensis clade), long rostrum (shorter in E. bonariensis clade), occipital region in lateral view is mildly curved (straight in E. bonariensis clade complex and E. wilsoni — Fig. 4), and reduced premetacrista on M 3 (long, N-shapped in E. bonariensis clade). From the species that occur in Peru, Eumops chiribaya has similar external and cranial dimensions to E. wilsoni and E. auripendulus (Table 5). Eumops auripendulus (and also E. maurus) is easily distinguished from E. chiribaya because it has a blackish pelage (cocoa brown in E. maurus), pointed tragus, different shape of skull, in particular, extended posterior portion of basicranium, and reduced premetacrista on M 3 (V-shaped) (Fig. 4). Eumops wilsoni (and also E. glaucinus) is similar to E. chiribaya (i.e. light brown dorsal pelage, square-shaped tragus, and premetacrista on M 3 slightly longer), but the shape of skull (shorter rostrum and wider post-orbital constriction) and ears relatively smaller (21.8 mm in E. wilsoni, 17-23 mm in E. glaucinus) distinguish both species from the E. chiribaya (Fig. 5). Very deep and wide basisphenoid pits also distinguish E. chiribaya from E. auripendulus, E. glaucinus, and E. wilsoni (Fig. 4). Eumops chiribaya differs from E. perotis and E. trumbulli based on the following combination of characteristics: smaller size (E. chiribaya has a medium body size and forearm shorter than in E. trumbulli and E. perotis - FA = 61, 65, and 79 mm, respectively); smaller ears, with ratio of length of ears/length of forearm reaching 0.42 in comparison with E. trumbulli and E. perotis, which have very developed ears (> to 0.49); basisphenoid pits are proportionally deeper in E. chiribaya than E. trumbulli and E. perotis; and its opisthocranion is curved dorsally and anteriorly whereas it is extended posteriorly in E. trumbulli and E. perotis (Fig. 4). Natural history. Eumops chiribaya inhabits in Coastal desert of southern Peru. The holotype was captured alive by a police officer during his patrolling in the locality El Algarrobal, Moquegua, Peru. He mentioned that the bat struck the top of a gate (approximately 5 meters high) and fell on the road, allowing him to catch the specimen with his own hands. The holotype had no ectoparasites nor showed signs of reproductive activity. The stomach content was not analyzed.Published as part of Medina, César E., Gregorin, Renato, Zeballos, Horacio, Zamora, Hugo T. & Moras, Ligiane M., 2014, A new species of Eumops (Chiroptera: Molossidae) from southwestern Peru, pp. 19-36 in Zootaxa 3878 (1) on pages 27-30, DOI: 10.11646/zootaxa.3878.1.2, http://zenodo.org/record/28733
