Full text linkSUMMARY The paper deals with an experimental method for diamond bead life time testing. The method is based on a testing machine for each single bead by machining parameter setting (contact force and cutting speed) equivalent to diamond wire cutting real conditions. The different techniques are described purposely developed for diamond condition analysis and wear evaluation as a function of the removed material by sintered beads during white Carrara marble and Perlato di Coreno cutting. RIASSUNTO L'articolo tratta un metodo sperimentale per sottoporre a prove di durata perline diamantate. Il metodo prevede l'uso di una macchina di prova per perlina singola con impostazione di parametri di lavorazione (forza di contatto e velocità di taglio) equivalenti alle condizioni reali del taglio con filo diamantato. Vengono descritte diverse tecniche appositamente sviluppate per l'analisi dello stato dei diamanti e la quantificazione dell'usura in funzione del materiale asportato con perline sinterizzate nel taglio di un bianco di Carrara e di un perlato di Coreno
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
Más allá del ver
No full text[ES] La exposición PAM!PAM! tiene como objetivo promover el talento de los jóvenes artistas valencianos.
Tras la finalización de los estudios de máster, el alumnado egresado inicia un periodo de profesionalización fuera del recinto universitario, en el que la Facultad de Bellas Artes UPV quiere seguir siendo activa, justo en el momento en el que necesitan un especial soporte. Con tal fin, se pone a disposición de los artistas ayudas para la producción de obra (con la financiación de la Fundación Hortensia Herrero), para que generen un proyecto expositivo específico para un espacio de la ciudad de Valencia. Anteriores ediciones tuvieron lugar en el Centre del Carme (20014-2016), IVAM (2017) y Sala Atarazanas (2018-2019), convirtiéndose en una de las exposiciones esperadas cada año para tomar el pulso a la creación artística emergente.Silvestre-Garcia, L.; Clemente Marco, JL.

Easy closure of anterior palatal fistula with local flaps
No full textBackground: Anterior palatal fistula is often observed in the treatment of the cleft palate with a push-back palatoplasty. High rate of incomplete closure is reported. We describe a reliable new technique with reverse local flaps to close an anterior palatal fistula. Materials and Methods: One hundred seventeen cleft patients, treated with push-back palatoplasty, underwent repair of an anterior palatal fistula by our group. Fistulas were located in the anterior hard palate, with a variable size between 0.1 cm to more than 0.5 cm. Two reverse local flaps from the nasal mucosa of the lateral palatal edges are used to close the fistula. A third flap is elevated from the premaxilla in bilateral clefts. The flaps are elevated toward the center of the fistula. The closure is made in 2 layers for unilateral cleft and in 3 layers for bilateral cleft, using absorbable sutures. Results: Complete closure of the anterior palatal fistula was achieved in 77 patients (65%) after the first surgery, 27 patients (23%) required a second attempt to close the fistula, and 10 patients (8.5%) required a third surgery. Three patients (2.5%) continued to have a fistula after 5 surgeries. Conclusions: We believe that our method is reliable and easy to perform, and it has a high success rate. The technique is indicated to correct small- to medium-size defects. © 2010 by Mutaz B. Habal, MD
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
