Labour outcome of women with successful external cephalic version - a prospective study
No full textLabour outcome for women following successful external cephalic version (ECV) was evaluated in a prospective case control study. ECV was successfully performed on 93 women in a dedicated ECV clinic at St Mary's Hospital, Portsmouth between 2004 and 2006. In the study group, 50% (n = 93) of women had a successful ECV. There were 103 women in the control group. There was no significant difference in the rate of instrumental deliveries between the study and the control groups. The rate for caesarean section was higher in the ECV group (18.2, n = 93) compared with the control group (7.7, n = 103; p < 0.028). When compared with the control group, the study group had a higher epidural rate (p < 0.016), oxytocin augmentation (p < 0.001), induction of labour rate (p < 0.009), electronic fetal monitoring (EFM) (p < 0.0001), abnormal fetal heart rate (p < 0.014) and birth in main unit (p < 0.001). Our data provide useful guidance to women undergoing ECV.PMID: 20121496 [PubMed - indexed for MEDLINE]<br/
Valor e sentimento moral na teoria kantiana
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas. Programa de Pós-Graduação em Filosofia.Há muito tempo, os leitores de Kant têm se questionado a respeito do valor que Kant atribuiu à ação por dever, pois parece moralmente repugnante não recomendar ações acompanhadas por algum sentimento ou inclinação para realizar o que se deve realizar. Esse problema já foi abordado por Schiller e atualmente alguns comentadores como Richard Henson, Barbara Herman, Paul Guyer e Marcia Baron tem discutido sobre o valor moral e a sobredeterminação da ação por dever em Kant. Entre os problemas a serem examinados estão: Quais as circunstâncias nas quais podemos dizer que alguém agiu por dever? A presença de incentivos cooperativos como, por exemplo, a simpatia e a compaixão, determinam que essa ação não foi feita por dever? Não deve existir qualquer outro sentimento moral, mas somente o dever na prática da ação moral? Com isso, pretendemos investigar o caráter e a função do valor e do sentimento moral na teoria kantiana, tanto em uma leitura da Fundamentação da Metafísica dos Costumes como na Doutrina das Virtudes e, assim, verificar se é possível a sobredeterminação da ação por dever e se há uma possibilidade de que incentivos como a simpatia possam estar presentes na prática da ação moral, sem invalidar seu valor moral
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
Money and Currency in African History
No full textAfrican peoples have managed multiple currencies, for all the classic four functions of money, for at least a thousand years: within each society’s own circuits, in regional exchange, and across the continent’s borders with the rest of the world. Given the materials of some of these currencies, and the general absence of formalized denominations until the colonial period, some early European accounts defined certain transactions as barter. The management of multiplicity is traced through four eras: a) the precolonial period, with some monies locally produced and acquired, and others imported through intercontinental trades, such as the Atlantic slave trade, and eventually under the expansion of capitalism to Africa; b) the colonial period, when precolonial monies, in some places, still circulated with official monies; c) postcolonial national monies for the new African states; and d) the most recent phase of multiplicity in use, due to migration and sales across borders as well as to the use of new technologies, such as mobile money. The management of multiplicity thereby has a long history and continues to be an inventive frontier. History and ethnography meet on common ground to address these dynamics through empirical study of money in practice, and broader scholarship has drawn on a large variety of original sources

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
Attention network forecasts time-to-failure in laboratory shear experiments
No full textRocks under stress deform by creep mechanisms that include formation and slip on small-scale internal cracks. Intragranular cracks and slip along grain contacts release energy as elastic waves termed acoustic emissions (AE). AEs are thought to contain predictive information that can be used for fault failure forecasting. Here, we present a method using unsupervised classification and an attention network to forecast labquakes using AE waveform features. Our data were generated in a laboratory setting using a biaxial shearing device with granular fault gouge intended to mimic the conditions of tectonic faults. Here, we analyzed the temporal evolution of AEs generated throughout several hundred laboratory earthquake cycles. We used a Conscience Self-Organizing Map (CSOM) to perform topologically ordered vector quantization based on waveform properties. The resulting map was used to interactively cluster AEs. We examined the clusters over time to identify those with predictive ability. Finally, we used a variety of LSTM and attention-based networks to test the predictive power of the AE clusters. By tracking cumulative waveform features over the seismic cycle, the network is able to forecast the time-to-failure (TTF) of lab earthquakes. Our results show that analyzing the data to isolate predictive signals and using a more sophisticated network architecture are key to robustly forecasting labquakes. In the future, this method could be applied on tectonic faults to monitor earthquakes and augment early warning systems
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
