Evaluation of the treatment costs and duration of topical treatments for multiple actinic keratosis based on the area of the cancerization field and not on the number of lesions
Full text linkBackground: The cost of topical treatments for actinic keratosis (AK) has historically been evaluated in relation to the number of lesions requiring treatment or simply by the price of a single tube/sachet of the drug used. Objective: To demonstrate a new method of costing topical treatments in AK, which takes into account the actual cancerization area treated. Methods: In order to evaluate the actual cost of each treatment, the official approval status of the drug was used to estimate the amount of cream needed per one cm 2 . This value was then applied to the hypothetical cancerization area sizes to demonstrate the impact of the size treated on the actual cost of treatment. The price considered was the ex-factory price in Italy. Results: Areas which could be treated with a single tube/sachet of Metvix ® , Picato ® , Aldara ® , Solaraze ® and Zyclara ® were 200, 25, 25, 33.3 and 200 cm 2 , respectively. For the treatment of smaller areas (<100 cm 2 ), treatment with Metvix ® was the most costly topical option in Italy. However, for the treatment of cancerization areas larger than 100 cm 2 , Metvix ® was the least expensive treatment option. Treatment with Metvix ® was least long, requiring a single day of treatment for an area of up to 200 cm 2 , compared with up to 224 days of treatment with Aldara ® for the treatment of a similar size. Conclusion: Changing treatment costing strategy in the management of multiple AKs towards costing per cancerization area instead of costing per lesion is a much more accurate representation of the ‘real world cost’ for AK
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

Polémiques et propos haineux dans les mèmes Internet autour de Greta Thunberg
No full textDans cette étude, nous nous proposons d’étudier les propos haineux et diffamatoires véhiculés par les mèmes
Internet ayant pour cible Greta Thunberg, activiste écologiste suédoise qui a fondé, en 2018, le mouvement
Fridays for Future dans le but de promouvoir le développement durable et, plus généralement, de diffuser
une conscience environnementale. Plus précisément, notre objectif est de comprendre si les stratégies
argumentatives et énonciatives utilisées par les détracteurs de la jeune militante dans les mèmes permettent
de véhiculer un véritable contrediscours écologiste ou si elles se limitent à une simple remise en question de
son autorité, fondée sur des propos essentiellement polémiques et haineu
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
