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
Risperidone or aripiprazole in children and adolescents with autism and/or intellectual disability: A Bayesian meta-analysis of efficacy and secondary effects
No full textSecond-generation antipsychotics (SGAs) induce frequent adverse effects in children and adolescents with each compound appearing to have a specific adverse effect profile. Aripiprazole and risperidone are FDA-approved medications for behavioral disturbances associated with autism and/or intellectual disabilities (ID) in children and adolescents. Using Bayesian meta-analysis of all relevant studies (N = 8; 18 arms: 782 patients), we aimed to calculate odds ratios (OR) or mean average effects to assess efficacy, weight gain, metabolic changes, sedation, and extra-pyramidal syndrome (EPS) of the two compounds. Reporting was incomplete to assess metabolic changes. Compared to placebo, significant treatment-related increases were observed for: CGI response with aripiprazole (OR = 6.09.95% credible interval [2.3-12.63]) and risperidone (12.8 [5.57-27.33]); weight gain with aripiprazole (OR = 6.28[1.64-17.12]) and risperidone (7.76[1.88-25.2]); EPS with risperidone (OR = 3.72 [1.73-7.22]); and somnolence/sedation with aripiprazole (OR = 25.76 [1.29-112.3]) and risperidone (9.63 [3.52-22.79]). There were no significant differences between active compounds. We conclude that short term efficacy of risperidone and aripiprazole are similar for behavioral disturbances associated with autism and/or ID, and that secondary effects are frequent. More research should be conducted on metabolic changes as current literature is lacking compared to other indications in youths. (C) 2012 Elsevier Ltd. All rights reserved
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
Self-efficacy as a mediator between involvement in intervention and quality of life in parents of children and adolescents with autism spectrum disorder
No full textPrevious studies have suggested that increased parental involvement in intervention for children with autism spectrum disorders (ASD) may be associated with improved parental Quality of Life (QoL). This study investigates the mediating role of parental self-efficacy in the relationship between involvement in intervention and QoL in parents of children and adolescents with ASD. One hundred and eighty-eight parents provided self-reported measures regarding demographics, involvement in intervention, self-efficacy, child's functioning and QoL (i.e., overall QoL and ASD symptoms-related QoL). After controlling for child's functioning, structural equation modelling showed that (a) self-efficacy partially mediates the association between direct involvement in intervention and overall QoL, b) after accounting for the mediator,a negative association emerges between direct involvement in intervention and overall QoL (i.e., suppression effect), (c) self-efficacy fully mediates the association between direct involvement in intervention and ASD symptoms-related QoL, (d) self-efficacy fully mediates the association between indirect involvement in intervention and ASD symptoms-related QoL. These findings extend previous literature by revealing the key role of parental self-efficacy, and are relevant to designing interventions aimed at supporting and improving family adaptation processes
A 0.12mm<sup>2</sup> Wien-Bridge Temperature Sensor with 0.1°C (3σ) Inaccuracy from -40°C to 180°C
No full text Resistor-based temperature sensors can achieve much higher resolution and energy efficiency than conventional BJT-based sensors [1], but they typically occupy more area (> 0.25 mm 2 ) and have lower operating temperatures (le 125 {circ} {C}) [2]-[4]. This work describes a 0.12mm 2 resistor-based sensor that uses a Wien-bridge (WB) filter to achieve 0.1 {circ} {C} (3 sigma) inaccuracy from - 40 {circ} {C} to 180 {circ} {C}. Compared to a state-of-the-art WB sensor [4], it occupies 6 × less area and achieves comparable relative accuracy over a 76% wider operating range.
