La política monetaria de la FED frente a la crisis de la covid-19: entre continuidad y ruptura
No full textCet article se propose d’analyser l’ensemble des mesures prises par la Fed pour faire face à la crise de la covid-19. Pour expliquer l’action de la Fed, nous replaçons ses interventions dans leur contexte en tenant compte des problèmes qu’elle a cherché à résoudre. Dans un premier temps, la Fed a abaissé son taux directeur à deux reprises pour le ramener à zéro. À la mi-mars, plusieurs marchés cruciaux sont devenus dysfonctionnels. La Fed a donc repris ses programmes de rachats d’actifs et rétabli des facilités de crédit et de liquidité qu’elle avait mis en place en 2008. Puis elle a étendu son champ d’intervention en créant de nouvelles facilités. Ces mesures ont permis d’éviter un effondrement du système financier américain. Mais elles risquent d’accentuer le processus de remise en question du rôle des banques centrales.This paper analyzes the measures taken by the Fed to deal with the covid-19 crisis. To explain the Fed’s interventions, we put them in their context by considering the problems it sought to solve. The Fed started by lowering its target rate to bring it back to the zero lower bound. In mid-March, several crucial markets became dysfunctional. Consequently, the Fed resumed its large-scale asset purchase programs and restored several credit and liquidity facilities introduced in 2008. It then expanded the scope of its interventions by creating new facilities. These measures prevented a collapse of the U.S. financial system. But they are likely to intensify the challenge faced by central banks concerning their role.Este artículo se propone analizar el conjunto de medidas adoptadas por la FED para hacer frente a la crisis de la covid-19. Para explicar las acciones de la FED, nosotros resituamos las intervenciones en su contexto teniendo en cuenta los problemas que ella busco resolver. En un primer tiempo la FED bajo su tasa en dos momentos para hacerla acercar a cero. A mediados de marzo 2020,icjos mercados estratégicos se convirtieron en disfuncionales.LA FED entonces retomó sus programas de compras de activos y restableció las facilidades del crédito y de liquidez que ella había puesto en marcha en 2008. Después ella extendió su campo de intervención creando nuevas facilidades. Estas medidas han permitido evitar el derrumbe del sistema financiero norteamericano. Pero ellas corren el riesgo de acentuar el proceso de puesta en cuestión del papel de los bancos centrales
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
