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

No full textCan you retrieve it? : pragmatic, morpho-syntactic and prosodic features in sentence topic types in Italian Sign Language (LIS)
No full textLa presente ricerca, avvalendosi di un approccio multi-disciplinare, indaga la realizzazione prosodica e le proprietà sintattiche di tre tipi di topic in LIS: aboutness, scene-setting e contrastivi. I risultati dimostrano che in LIS, i topic aboutness e scene-setting sono accompagnati da due marker prosodici: le sopracciglia-alzate e la tensione-oculare. Quest’ultimo ricopre anche una funzione pragmatica come marcatore di accessibilità. Entrambi i tipi di topic possono essere separati dalla restante parte della frase da due marker di confine frasale: il battito-cigliare e il cenno del capo in avanti.
Lo studio sui topic contrastivi ha evidenziato l’uso di strategie prosodiche, (i movimenti laterali del busto) e sintattiche, (l’uso di loci segnici differenti) come espressione di contrasto.
Questo studio indaga anche le strategie linguistiche messe in luce dai segnanti, focalizzandosi sulla gestione dell’informazione data, la quale può essere codificata in forma di sintagmi nominali, pronomi o argomenti nulli. In linea con la massima di quantità, i risultati in LIS dimostrano che i segnanti compiono delle scelte linguistiche specifiche in relazione al grado di accessibilità e allo status informazionale dei referenti, i quali possono essere mantenuti salienti o reintrodotti nel discorso. Nello specifico, la scelta dei sintagmi nominali è statisticamente correlata con lo status di referenti reintrodotti e con il contorno prosodico marcato dalla tensione oculare. La sintassi, dunque, sembra ricoprire un ruolo importante e mediano rispetto allo status pragmatico e alla realizzazione prosodica dei referenti
Materiales Didácticos. Una metodología para su producción en la era de las TIC
No full textEl presente trabajo de Tesis propone un protocolo que aporta a la planificación estratégica de la producción de materiales didácticos (MD) para la educación mediada por tecnologías de la información y la comunicación (TIC). Para alcanzar este objetivo se consideró necesario realizar la revisión de algunos modelos propuestos desde la aparición de las TIC en la escena educativa. La intención del análisis fue determinar las características del proceso de producción de MD e identificar fortalezas y debilidades en cada uno de estos modelos, cuya selección consideró su pertenencia al ámbito universitario nacional o internacional y/o la experticia de los autores. Los resultados desprendidos de la revisión constituyeron las bases sobre las que se propone un proceso de producción detallado que considera las diversas variables intervinientes organizadas en grupos conceptuales.Fil: Calderone, Marina.

Synthesis and biological activity of novel substituted benzanilides as potassium channel activators. V
No full textAs part of our program toward designing potassium channel openers, the synthesis of a novel series of substituted benzanilides and their vasodilating activity are presented. The facile synthetic pathway generally involves coupling between the appropriate benzoyl chloride and commercial available anilines, followed by the selective or non-selective cleavage of methyl ether substituent(s), affording the corresponding phenol or bisphenol derivatives. The pharmacological evaluation of these structurally novel potential BK-openers on vascular contractile activity was studied in vitro, using isolated rat aortic rings pre-contracted with KCl 20 mM. Some derivatives were found to be potent smooth muscle relaxants and the vasodilation effects of these compounds were inhibited by tetraethyl ammonium (TEA) and iberiotoxin (IbTX), suggesting that the opening of BK channels is prevalent in the mechanism of action of these compounds. The best compound of the series was N-(2-hydroxy-5-phenyl)-(2-methoxy-5-chloro)-benzamide (16b) showing a full vasorelaxant efficacy and almost nanomolar potency index. (C) 2004 Elsevier SAS.

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
Advanced Data Analysis for Observational Cosmology: applications to the study of the Intergalactic Medium
No full textThe analysis of absorption features along the line of sight to distant sources is an invaluable tool for observational cosmology, giving a direct insight into the physical and chemical state of the inter/circumgalactic medium. Such endeavour entails the accessibility of bright QSOs as background beacons, and the availability of software tools to extract the information in a reproducible way. In this article, we will present the latest results we obtained in both directions within the QUBRICS project: we will describe how machine learning techniques were applied to detect hundreds of previously unknown QSOs in the southern hemisphere, and how state-of-the art software like QSFit and Astrocook was integrated in the analysis of the targets, opening up new possibilities for the next era of observations...
