Variations on the Author
No full text“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
RETRACTED: Cannabidiol (CBD) From Non-Cannabis Plants: Myth or Reality?
No full textReports on the occurrence of cannabidiol (CBD, 1) in non-cannabis plants are critically reviewed. The isolation of 1 from Humulus Kriya (sic) was fraudulent and from Trema orientalis and stevia dubious, while the occurrence of traces of 1 in flax needs additional confirmation. The presence of high concentration of cannabigerol (CBG, 3a) and its corresponding acidic precursor (GBGA, 3b) in Helichrysum umbraculigerum could not be confirmed, but this plant deserves additional attention due to the possible phytocannabinoids accumulation in selected chemotypes
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

No full textDispelling 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

A numerical assesment of the effect of MRI surface coils on implanted pacemakers
No full textElectromagnetic interaction between a radio frequency surface coil for magnetic resonance imaging (MRI) and a heterogeneous human model implanted with a pacemaker system has been studied in order to provide safety requirements and to estimate potential damaging of the device. Since the coil can be considered an electrically small structure, an equivalent model has been considered and validated in order to reduce calculation burden in time domain simulation by using a Finite Integration Technique (FIT
Banca en la Sombra: regulando el futuro con las dudas del pasado
No full text“Banca en la sombra”, o “sistema bancario en la sombra” es el término utili- zado por el Financial Stability Board (FSB) para promover una nueva batería de reformas en la regulación nanciera. El término se ha establecido tanto en los estudios académicos como en las propuestas de regulación por parte de distin- tos organismos como el propio FSB, el Comité de Basilea para la Supervisión bancaria (CBSB, o BCBS, en su acrónimo en inglés), la Organización Internacio- nal de Comisiones de Valores (IOSCO), o la propia Comisión Europea.
Se trata de un concepto sugerente, y, a la vez, inquietante, que describe un fenómeno con- sustancial a la regulación. Si esta es efectiva, genera un incentivo para que los operadores realicen una actividad funcionalmente equivalente fuera de los límites marcados por las normas: cuando se mani estan los primeros síntomas de la crisis, la con anza se evapora de manera súbita, revelando la fragilidad del sistema no regulado, y contagiando al sistema regulado
