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.

Metodi Alternativi di Risoluzione delle Controversie: un’analisi empirica dei costi e benefici per le imprese
No full textLa ricerca si svolge su tre piani: 1) un piano meramente ricognitivo dello stato di fatto degli strumenti alternativi di risoluzione delle controversie in Italia ed in alcuni sistemi giuridici stranieri rilevanti; 2) un piano aziendalistico di misurazione degli effetti perversi dell’inefficienza del sistema giurisdizionale sul bilancio di esercizio di un campione rappresentativo di imprese; 3) infine, un piano neo-istituzionale per individuare i vantaggi comparativi di lungo periodo offerti da un sistema in cui vi sia una cultura giudiziaria, accademica e professionale ispirata al modello della mediazione, della risoluzione stragiudiziale dei conflitti.
La novità importante della ricerca è quella di condurre in modo congiunto un’analisi quantitativa ed una comparativa neo-istituzionale. Per la prima volta si conduce un’analisi della convenienza economica alternativa dei procedimenti arbitrali e di conciliazione rispetto al giudizio ordinario; il procedimento si articola nella valutazione di:
a. Tipologie di contenziosi maggiormente ricorrenti per le PMI e valore economico dei medesimi per le parti.
b. Durata media dei contenziosi ed identificazione degli eventi che ne condizionano la tempistica.
c. Modalità di gestione del contenzioso ed elementi utilizzati nel processo decisionale.
d. Costi espliciti ed impliciti delle modalità di gestione del contenzioso.
e. Elementi che condizionano psicologicamente il comportamento degli attori nelle scelte di gestione del contenzioso.
L’analisi è perseguita mediante la realizzazione congiunta dei seguenti percorsi di ricerca:
1. Elaborazione ed analisi di dati empirici relativi ai giudizi ordinari
2. Elaborazione ed analisi di dati empirici relativi alle Camere Arbitrali
3. Analisi dei dati di bilancio relativi al contenzioso ed al rischio legale
4. Analisi mediante questionari di tipologie e costi (espliciti ed impliciti) del contenzioso
5. Ricerca mediante “esperimenti di laboratorio” con gli attori del contenzioso
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

No full textL’étude de l’eau, sous ses différents aspects, relève de disciplines nombreuses mais l’hydrologie, science de l’eau s.s., n’a pas l’importance que l’on pourrait attendre. Ce constat est surtout vrai pour les pays francophones, dans ce domaine scientifique largement investi par les travaux de langue anglo-saxonne. C’est l’une des raisons pour lesquelles la publication de l’ouvrage d’André Musy et Christophe Higy ne peut qu’être saluée. Cet ouvrage a bien d’autres mérites, bien évidemment, en p..
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
