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

Introduction by Dr Christina Faull; edited interview with Professor Patrick Wall.Annotated and edited transcript of a Witness Seminar held on 12 December 2002. Introduction by Dr Christina Faull; edited interview with Professor Patrick Wall.Unrelieved pain caused by cancer is experienced by more than 5 million people worldwide, and over the past 50 years has been accepted as unnecessary by both clinicians and politicians. Major innovations in the understanding of pain and our ability to treat it have been made. This Witness Seminar, chaired by Professor David Clark, describes the development of pain clinics, the introduction of the hospice in Britain, and global implementation of innovative technologies for cancer pain relief and advances in research during the latter part of the twentieth century. International health planners argue that the outstanding challenge is to put this knowledge into practice in healthcare settings around the world, often where resources are limited.

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
Laparoscopic placement of peritoneal dialysis catheters: 7 years experience
No full textJournal compilation © 2009 Royal Australasian College of SurgeonsBackgroundSince 1994 we have placed all peritoneal dialysis (Tenckhoff) catheters at our hospital laparoscopically using a technique that incorporates suture fixation into the pelvis. The purpose of this study was to determine the long-term outcome of this approach.MethodPerioperative and follow-up data for all patients undergoing placement of a peritoneal dialysis catheter at the Royal Adelaide Hospital were collected prospectively and managed on unit specific and hospital wide computerized databases. A total of 148 procedures were carried out in 123 patients from March 1994 to November 2001. Follow-up ranged from 3 to 68 months (median, 42 months). All procedures were undertaken or supervised by one surgeon, and catheters were routinely sutured into the pelvis at laparoscopy.ResultsThere was no perioperative mortality in this series, and only one catheter could not be placed laparoscopically. This was in a patient with extensive intra-abdominal adhesions. Mean operative time was 27 min (range, 10-100 min), and mean postoperative stay was 2.8 days (range, 1-12 days). Seven (5%) patients experienced peri/postoperative haemorrhage, and four of these underwent surgical re-exploration. Twenty-five (17%) catheters are still used for dialysis. Thirty-four (23%) catheters were removed when the recipient received a subsequent renal transplant, and 42 (28%) patients died during follow-up. Forty-six (31%) patients required catheter revision or removal because of technical problems; 26 (18%) recurrent peritonitis or exit site infection; and 20 (14%) catheter blockage. Twenty-eight reinsertion procedures were carried out in 25 patients. Ten (7%) patients developed port site hernias at late follow-up, and required hernioplasty. Catheter migration leading to malfunction (poor drainage) occurred in eight (5%) patients only.ConclusionsLaparoscopic placement of peritoneal dialysis catheters is a safe and effective procedure. The majority of patients will dialyse successfully using this technique. Suturing the catheter tip into the pelvis is associated with a low rate of catheter migration.Cu T. Lu, David I.

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.

Comparing Emotional Communities: Moravians, Methodists and Halle Pietists
No full textIn this paper I will lay out the framework for comparing emotional vocabularies, using two corpora of first-person narratives from the Moravian Church and the Methodist Church from the mid-18th century. The Moravian texts are from the Fetter Lane congregation in London and the majority of the manuscripts are to be found at Moravian Church House. These texts have been transcribed, encoded and published on the Moravian Lives website. The Methodist corpus is compiled from a project housed at the Rylands Library in Manchester, which contains letters of petition to Charles Wesley tranbscribed by volunteers and available online at (https://www.library.manchester.ac.uk/services/digitisation-services/projects/rapture-and-reason/)
As McGuire and I have shown in our previous study (Faull and McGuire 2022), applying computational analysis to text corpora can help to identify emotional communities in which common patterns and sentiment lexica can be found. This paper will begin to address these questions by:
a) identifying the emotional vocabularies or sentiment dictionaries of personal narratives of members of the Methodist and Moravian churches in Northern England in the eighteenth century;
b) exploring a methodology for measuring those sentiments and offer alternate methods for analysis and interpretation
c) asking whether such a comparative perspective could be applied to the personal papers of Halle Pietists. I make this claim based on Hindmarsh\u27s argument that, Zinzendorf’s dispute with the Halle pietists on the necessity of the Busskampf as proof of conversion in 1740 is simultaneous with the contact with the Wesleys and Methodism. In Hindmarsh’s eyes, this meant that the Moravians and their followers were able to distinguish their own piety from that of the Methodists in the same way: Methodism was Hallensian Pietism redivivus (Hindmarsh 165
