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
El sentido trágico de La casa grande de Álvaro Cepeda Samudio
No full textEste trabajo es un estudio comparativo entre La casa grande de Álvaro Cepeda Samudio y Orestíada de Esquilo, el cual procede de un interés por explorar las posibles relaciones entre tales tragedias y novela, desde un análisis de estos géneros literarios y pasando por la indagación respecto del carácter mítico de ambas obras y de los personajes arquetípicos representados tanto en la novela de Cepeda Samudio como en la trilogía de Esquilo.Magíster en Estudios LiterariosMaestrí

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

Regional distribution of fractures in the southern Edwards Plateau and their relationship to tectonics and caves
No full textBureau Publication GC7802 - to purchase a print copy please go to: https://store.beg.utexas.edu/geologic-circulars/436-gc7802.htmlIn order to better understand the control exerted by fractures on the recharge and production zones of limestone aquifers, the authors delineated surficial fracture zones in the southern Edwards Plateau, Texas. Lineations were marked on nearly 200 mosaics scale of 1:24,000. Approximately 400 fracture zones were identified on each mosaic. Moving averages of the density and orientation of fracture zones were computed in order to map (1) number of fractures, (2) length of fracturing, (3) distribution of fracture intersections, (4) weighted arithmetic mean of fracture orientation in northeast and northwest quadrants, and (5) standard deviation of the means. All were calculated per unit area. In addition, rose diagrams were computed for selected areas, generally a standard 7.5-minute quadrangle.
The method introduced bias in that (1) fracture zones were identified with greater difficulty at the margins of mosaics, and (2) more north-south and east-west fracture zones were observed in field measurements than in aerial photographic interpretations. The fractures appear controlled both by an old system of basement fracturing and by the trend of the relatively young Balcones fault system. The basement system contains prominent northeastward and northwestward-trending sets, and north-south and east-west-trending subsets. Fractures related to the Balcones fault zone trend east-west in the western Edwards Plateau and generally approach north in the eastern plateau. Cave passageways in the western plateau appear to parallel fracture zones trending northwestward, northeastward, and westward, whereas abundant cave corridors of eastern caves commonly align with the principal faults of the Balcones fault zone.Bureau of Economic GeologyUT Librarie
Detectability of testosterone esters and estradiol benzoate in bovine hair and plasma following pour-on treatment
No full textThe abuse of synthetic esters of natural steroids such as testosterone and estradiol in cattle fattening and sports is hard to detect via routine urine testing. The esters are rapidly hydrolysed in vivo into substances which are also endogenously present in urine. An interesting alternative can be provided by the analysis of the administered synthetic steroids themselves, i.e., the analysis of intact steroid esters in hair by liquid chromatography tandem mass spectrometry (LC/MS/MS). However, retrospective estimation of the application date following a non-compliant finding is hindered by the complexity of the kinetics of the incorporation of steroid esters in hair. In this study, the incorporation of intact steroid esters in hair following pour-on treatment has been studied and critically compared with results from intramuscular treatment. To this end animals were pour-on treated with a hormone cocktail containing testosterone cypionate, testosterone decanoate and estradiol benzoate in different carriers. The animals were either treated using injection and pour-on application once or three times having 1 week between treatments using injection and pour-on application. Animals were slaughtered from 10–12 weeks after the last treatment. Both hair and blood plasma samples were collected and analysed by LC/MS/MS. From the results, it is concluded that after single treatment the levels of steroid esters in hair drop to CCß levels (5-20 µg/kg) after 5-7 weeks. When treatment is repeated two times, the CCß levels are reached after 9–11 weeks. Furthermore, in plasma, no steroid esters were detected; not even at the low microgramme per litre level but-in contrast with the pour-on application-after i.m. injection, significant increase of 17ß-testosterone and 17ß-estradiol were observed. These observations suggest that transport of steroid esters after pour-on application is not only performed by blood but also by alternative fluids in the animal so probably the steroid esters are already hydrolysed and epimerized before entering the bloo
