SUPerfici & Ricoprimenti per la Meccanica Avanzata e la Nanomeccanica
No full textSi propone la costituzione di un laboratorio regionale (Net-LAB SUP&RMAN) focalizzato sulle tematiche tecnologico-scientifiche delle superfici e delle modifiche superficiali, dei ricoprimenti e delle nanotecnologie meccaniche, in grado di produrre un avanzamento delle conoscenze che sia di grande impatto tecnologico sulla realtà produttiva emiliano-romagnola, in particolare in relazione alla possibilità di collocarsi strategicamente, in condizioni competitive, sul mercato globale. Si propone di operare attraverso il coordinamento delle attività di ricerca pubblica e
privata attualmente presenti sul territorio, in coerenza con gli obiettivi del PRRIITT della Regione Emilia Romagna e
per la realizzazione dei più generali obiettivi del Distretto Hi-Mech. La fattibilità della proposta poggia sulla
presenza, sul territorio regionale, di istituzioni scientifiche che hanno raggiunto, nel settore delle superfici solide, dei
ricoprimenti ed in generale della nanoscienza, livelli di eccellenza ampiamente riconosciuti a livello nazionale ed
internazionale, e di una realtà industriale caratterizzata da una produzione di alta qualità e solida collocazione sui
mercati anche internazionali, che esprime l’esigenza di accedere ad un patrimonio di conoscenze ritenute essenziali per il proprio sviluppo. Si intende operare attraverso tre principali azioni: i) la promozione di un significativo avanzamento e di una reale integrazione della ricerca di base e applicata, operando con modalità progettuale su obiettivi ben definiti, così da realizzare un significativo breakthrough nelle competenze; ii) la creazione di linguaggi e competenze trasversali tra gli attori della ricerca e tra questi e il mondo produttivo, che consenta un efficace azione di trasferimento tecnologico; iii) una acquisizione di strumentazione e di personale che consenta di affrontare tematiche innovative ad
un livello di eccellenza nazionale ed internazionale

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
Magnetic anisotropies in Focused Ion Beam sculpted arrays of submicrometric magnetic dots
No full textThanks to its high sputtering efficiency and high spatial resolution, Focused Ion Beam (FIB) apparatus has been proved to be effective in isolating magnetic units by direct removal of selected portions of a thin film, at variance with the lithographic process, which involve resist process, etching and cleaning steps. The results is an extremely flexible, reproducible and clean fabrication process. we present a systematic study of the dependence of the surface morphology and geometric shape of Fe square elements and ferromagnetic/antiferromagnetic Fe/NiO bilayer square elements on the FIB parameters. We shown that the final quality of the geometries that can be obtained by FIB milling as well as the residual damage strictly depend on beam parameters (like spot size and pixel dwell time) and on the swelling properties of the patterned materials
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
