Antenna clavate, antennomeres 7–10 transverse, forming a loose club; apical antennomere subcircular; antennomeres 7–11 with stellate sensoria. Mentum with acute median keel raised anteriorly to a point (Figs. 10, 12). Ventral portion of eye not reaching subgenal sulcus (Fig. 8); ventral ocular depression present (Fig. 197).

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text linkWe 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

J.-B. Say's 1803 Treatise and the Coordination of Economic Activity
Full text linkAlthough historians of economic thought emphasize J.-B. Say's contributions to utility theory, the structure of the subject matter of economics, entrepreneur theory and the construction of the "law of markets," they rarely appreciate what Say accomplished in the first edition of the Traité d'Économie Politique. Only in chapters 21 and 22 of his 1803 Treatise, however, does Say sketch business firms as institutions that create and operate markets. In doing so, he essentially provides the basis for a non-walrasian concept of the coordination problem of a decentralized economic system. Thus, concerning Adam Smith's metaphor of the "invisible hand," Say ought to be considered as the first theorist to introduce into economic literature what Robert W. Clower called the "visible fingers" of the "invisible hand." --Invisible Hand,General Equilibrium Theory,Jean-Baptiste Say,Market Maker,Say's Law,Des Débouchés
Cephennium anophthalmicum Brendel B 1889
No full textCephennium anophthalmicum Brendel, 1889 Figs 1A, 2A, 3A, 5A, 6 Type Material. Not seen. A holotype was not designated for this species. However, it was described from a single specimen from Alameda County that was sifted from vegetable debris together with a large number of Pinodytes cryptophagoides (currently Catopocerus cryptophagoides) by Marie Fuchs (Brendel 1889). We attempted to track down this specimen but were not able to locate it at either the Academy of Natural Sciences in Philadelphia, the original repository of the Brendel collection, or the Museum of Comparative Zoology at Harvard University, the current repository for the Brendel collection. However, we did see a specimen from the MCZC that was determined as C. anophthalmicum from Alameda County. Because the label data do not exactly match the information presented by Brendel (1889) we believe this is only a topotype, and not a primary type. We choose not to designate a neotype here as it is possible that the original type specimen is still in existence somewhere. Material Examined. “ Alameda; Co. CAL.”/ “ Laundry; Farm ”/ “H. C.

Calif; IV-29-1970 ”/ “ex. Redwood; Litter”/ “Collector; T.R.Haig ” (1 FMNH [female, disarticulated]). Diagnosis. This species can be distinguished from its California congeners by the character combination of the absence of eyes, humeral angle of elytron bluntly angulate (Fig. 1A), and the absence of a basal elytral sutural ridge. Cephennium anophthalmicum most closely resembles C. urbanum, but can be separated from it by the presence of a basal elytral sutural ridge (Fig. 1G), and the apex of the mesosternal keel divergent and crescent-shaped in C. urbanum (Fig. 2G). It can be easily distinguished from C. aridum, C. celsifrons, and C. mariposae by the presence of eyes in these species (Fig. 4A, C-D), and can be separated from C. grandarboreum, C. canestroi and C. gilberti by the humeral angle of the elytron, which is raised, dorsally flattened and apically rounded in these three species (Fig. 3 D-F).

Body elongate, slender, weakly convex; testaceous; evenly and moderately pubescent; pubescence golden, slender, moderately long, weakly decumbent (Fig. 1A). Dorsal surface of head smooth, weakly pubescent, narrowing anteriorly from antennal insertions. Eyes absent. Antenna setose, antennomere I and II longer than broad, antennomeres III-VI quadrate and smaller than antennomeres II and VII, an- tennomere VIII smaller than antennomeres VII and IX, antennomeres IX-XI gradually clavate forming a loose club.

Hypomeron smooth, sparsely setose towards anterior quarter and along outside (lateral) edge. Prosternum lacking protuberant nodules anterolaterad procoxal cavities (Fig. 2A). Elytra smooth, as pubescent as pronotum, covering all abdominal segments; elytral suture flat; basomedial fovea present on each elytron; fovea moderate in size, moderately pubescent (Figs. 1A, 3A). Humeral angle of elytron projecting laterally to blunt point, dorsally raised and flattened (Fig. 3A). Scutellum weakly triangular, lacking setae (Fig. 3A). Mesosternal keel sparsely setose, lacking scale-like microsculp- ture, posterior quarter impunctate, apex weakly bifid (divergent), divergent projections short, triangulate (Fig. 2A). Metathoracic wings vestigial. Femora strongly clavate in distal half, tibiae expanded and becoming more densely setose towards distal half. Five visible abdominal sternites, ventrites V and VI partially fused. Aedeagus strongly sclerotized, with median lobe basally rounded, pill-shaped; parameres thin, sinuate, bisetose apically, extending to apex of rather narrow, bluntly triangular median dorsal process; apical digiform process curving ventrad at apex, extending just beyond apical collar; membranous apical collar with sclerotized clasper-like processes extending from apex; membranous lateral flaps present at base of apical collar (Fig. 5A). Female. Identical to male. Biology. This species was first described from a single specimen that was sifted from vegetable debris. An additional specimen was sifted from forest duff. Beyond this, there is little known about the biology of this species. Distribution. This species has been collected around the San Francisco Bay Area in central coastal California (Fig. 6).Published as part of Hopp, Katie & Caterino, Michael, 2009, Seven new species of Cephennium Müller & Kunze (Coleoptera, Staphylinidae, Scydmaeninae, Cephenniini) from California with a key to native North American species, pp. 31-54 in ZooKeys 24 (24) on pages 34-38, DOI: 10.3897/zookeys.24.247, http://zenodo.org/record/57654
