Corneal explantation activity in 2002: An analysis of the modified operational schedule
No full textAfter data have been gathered about corneal explants performed within the AOP health-care web throughout 2001, the resulting findings were used to update the selection system for donation fitness and operational procedures. The rejection of anti-HBc-positive grafts and tissues coming from subjects more than 79 years old resulted in decreased donations (256 donations, that is 492 corneal explants in 2001 vs 140, that is 273 in 2002), although the number of deaths was unchanged (1298 in 2001 vs 1294 in 2002). Corneas fit for transplantation did not change in number-126 (25.6% of the total available) in 2001 and 113 (41.4%) in 2002-while the instances of rejected corneas occurred 56.3% less frequently, allowing a savings of great deal of human and money resources. After activity schedules were modified, the results analysis confirmed the expected improvement in 2001
MOPP CHEMOTHERAPY VERSUS EXTENDED-FIELD RADIOTHERAPY IN THE MANAGEMENT OF PATHOLOGICAL STAGES I-IIA HODGKINS-DISEASE
No full textIn order to assess whether mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) chemotherapy (CT), which is less expensive and more easily available than radiotherapy (RT), is at least as effective as RT in terms of cure rate and has less iatrogenic damage, 89 consecutive patients with Hodgkin's disease (HD) (pathological stage I-IIA) were randomly allocated to receive mantle plus lumbar bar RT (36-45 Gy) or CT (six courses of MOPP). Forty-five patients were entered in the RT group and 44 in the CT group. The median follow-up was 60 months. Complete remission (CR) was obtained in all patients in the RT group and in 40 of 44 patients in the CT group. Overall survival (OS) and disease-free survival (DFS) were, respectively, 87.2\% and 72.7\% in the CT group and 93.5\% and 74\% in the RT group. Survival probability of relapsing patients was 76\% for the patients in the RT group and 45\% in the CT group. Treatment-related complications were more severe in the CT group as compared with the RT group
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
