Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Claudiagryllacris Cadena-Castañeda 2019, n. gen.
No full textClaudiagryllacris n. gen. Diagnosis: Size and shape of body more or less similar to those other medium size gryllacridines as Afrogryllacris and Echidnogryllacris (16–20 mm.) (Fig. 33). Head with a medium size and ovoid median ocellus, lateral ocelli with similar size but more rounded than the median ocellus, space between antennal cavities as wide as scape (Figs. 34, 35); fore coxae with a small and unarticulated spine, legs moderately long, slender, with four pairs of movable ventral spines on fore and middle tibiae; wings well developed, long and surpassing considerably the apex of abdomen. Abdomen without traces of femoro-abdominal apparatus; 10 th abdominal tergite of the male covered partially the epiproctus and with the posterior edge little obtuse prolongated; paraprocts and cerci simple; male subgenital plate rectangular, wider than long, with simple styles and with a prolongation on the middle of the notch (based on only male known to this genus) (Fig. 36). Female abdomen with unspecialized tergites; female genital plate simple and triangular; ovipositor long and slightly curved, rather thin and with narrowly rounded (almost acute) apex (Fig. 33). Included species: Type species: Claudiagryllacris finoti (Karny, 1932) n. comb. and three additional species: C. stigmata (Brunner von Wattenwyl, 1888) n. comb., C. lemur (Griffini, 1909b) n. comb., C. fryeri (Bolívar, 1912) n. comb. (all species previously placed in Niphetogryllacris). Etymology: Dedicated to Dr. Claudia Hemp as a recognition for her contributions to African Orthoptera knowledge and for her willingness to provide aid and data for this research, plus typical termination— gryllacris common to genera of this family. Comparison: The new genus differs from the African genera and others related taxa in a modest prolongation of the male abdominal apex, hooks absent (well developed in Afrogryllacris) and middle prolongation on the notch of the male subgenital plate. The females of this genus differ from the others by its longer and thin ovipositor in contrast of the medium size, up-curved and acute ovipositor of Echidnogryllacris. Also Claudiagryllacris differs from Pissodogryllacris (other genus found in Madagascar and adjacent islands too), for its hyaline wings, in Pissodogryllacris the wings are opaque. Distribution: Madagascar.Published as part of Cadena-Castañeda, Oscar J., 2019, A proposal towards classification of the Raspy Crickets (Orthoptera: Stenopelmatoidea: Gryllacrididae) with zoogeographical comments: An initial contribution to the higher classification of the Gryllacridines, pp. 1-100 in Zootaxa 4605 (1) on page 12, DOI: 10.11646/zootaxa.4605.1.1, http://zenodo.org/record/286048

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.
