Der Fund bei Nax gelang im Bereich eines sonnenexponierten, verwitternden Kalkaufschlusses und ist der erste in der subalpinen Zone. Der Standort ist warm und gut drainiert. Schnee kann rasch schmelzen und abfliessen. Der Frost wird wohl Steine spalten, doch eher nicht in die Lücken dazwischen eindringen. Der wärmebedürftige C. cintus konnte sich nur wegen dieser speziell günstigen Bedingungen an diesem hochgelegenen Ort ansiedeln.Published as part of Hoess, René, 2019, Interessante Neufunde von Laufkäfern (Coleoptera: Carabidae) aus der Schweiz - 3.

Obwohl die wenigen bekannten Funde von A. cursitans locker über die ganze Schweiz verteilt sind, wurde die Art in den letzten zwei Jahrzehnten nur noch bei Basel und im zentralen Wallis gefunden. Und obschon das Phänologiediagramm in Luka et al. (2009) nicht darauf schliessen lässt, könnte – wie die jetzigen Funde zeigen – die Art leichter im Herbst zu finden sein. Im Bereich der Rebberge halten sich die Tiere dann bei Temperaturen über 10 °C im Schatten von Mauern auf. Sinkt die Temperatur unter 10 °C, findet man sie auch an besonnten Stellen. Sie liegen tagsüber reglos unter Falllaub und im Detritus, teilweise auf Kopfsteinpflaster oder Beton und sind dadurch nur schlecht zu sehen. Auffällig – im Vergleich mit den nächst verwandten Arten – sind die stark vorstehenden Augen (Abb. 2b). Die Fühler können ausnahmsweise auch einfarbig hell sein; eine Verwechslung mit der noch selteneren A. fusca Dejean, 1828 kann dann aber aufgrund der schmaleren Körperform und der etwas geringeren Grösse ausgeschlossen werden.Published as part of Hoess, René, 2019, Interessante Neufunde von Laufkäfern (Coleoptera: Carabidae) aus der Schweiz - 3.

Kosterin leg., in RMNH and the author’s collection. Female. Head (Fig. 6 h–i): top black above level of anteclypeus upper margin, yellowish below (Fig. 6 h); vertex with a broad bluish yellow transverse stripe with irregular margins (Fig. 6 i). Labrum yellow with a small black central spot at upper margin. Anteclypeus ochre-yellow with a black central stripe and a pair of transversally elongate black spots at lower margin (Fig. 6 i). 1 st antennal segment black with a yellow apex; rest blackish brown with a lighter brown apex of 2 nd segment. Eyes in life with a dark brown upper half interrupted by a narrow greenish horizontal streak, bluish beneath.

A broad irregular light stripe across the vertex; yellow anteclypeus with a black central stripe and a pair of lateral dark spots, yellow labrum with a small black central spot, broadly separated processes of the prothorax posterior lobes, bicolored legs and abdomen, dorsal light streaks on S 8–9 and light S 10 dorsum may help identification of females of P. doisuthepensis. They are similar to those of P. hoffmanni, but in the latter the black pattern is more extended throughout the body (Fig. 1 c), the posterior processes of the prothorax are set closer to each other and converging (Fig. 3 c, 4 c), and the anteclypeus is black (Fig. 4 i,j). Males of P. doisuthepensis from Mondulkiri Province of Cambodia differ from the original description of the species from North Thailand (Hoess 2007) in having the S 9 blue spot diamond-shaped or roundish rather than triangular and the paraproct attenuated apical part entirely yellow instead of black outside.Published as part of Kosterin, Oleg E., 2015, Prodasineura hoffmanni sp. nov.

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

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.

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
