Valutare l'orientamento. Progetto di monitoraggio e valutazione degli interventi di orientamento della Regione del Veneto
No full textIl volume, con un saggio di guida all’interpretazione dei risultati a cura dall’autore, presenta i contributi del progetto di monitoraggio e valutazione degli interventi di orientamento, finanziati dalla Regione del Veneto nel periodo 2007-2008. Tali iniziative sono caratterizzate dalla costituzione di Reti tra attori del territorio a cui hanno aderito scuole secondarie di primo e secondo grado, centri di formazione professionale e organismi di formazione e orientamento, per la realizzazione di interventi integrati di orientamento che si rivolgono a giovani in diritto-dovere di istruzione e formazione e ad adulti. La finalità del progetto è stato di sviluppare e migliorare il lavoro svolto dalle reti, attraverso una valutazione qualitativa e quantitativa degli interventi e l’individuazione di modalità di miglioramento degli interventi realizzati. I risultati raggiunti sono stati quelli di costruire un “modello di valutazione condivisa” fondato sul coinvolgimento degli operatori di orientamento, la rilevazione di alcune buone pratiche, la formulazione delle linee guida di miglioramento del sistema regionale
Statistical modelling for the time projection chamber signal processing: how can statistics improve detector performances?
No full textThe aim of this contribution is to investigate on how to improve the extraction of physical information from the signals coming from a liquid Argon (LAr) time projection chamber (TCP), a particle detector technique characterized by good tracking and energy measurement capabilities. We present here the results obtained from the analysis of test pulse data, i.e. the electronic impulses that, on purpose of calibration and testing, stimulate the electronics simulating a known charge value as if it was released by a particle within the LAr. Starting from the analysis of those calibration data, we focused on getting a better modelling of the electronic noise, which results far from a white noise process. As a subsequent step, we identified a more suitable theoretical analytical function to perform the nonlinear least-squares fit of the signal, used to recover the parameters which are relevant for the physical analysis
A technology enhanced model of peer review: an exploratory research in Italian school contexts
No full textProgettualità e attività
No full textI progetti di orientamento per adulti progettati e realizzati dagli Enti presi in esame, hanno insita in loro una dimensione educativa e formativa dell'orientamento che è stata esaminata in ambito quantitativo e in ambito qualitativo a partire non
solo da quelli che sono stati i contenuti formativi proposti, ma anche dalle eventuali modalità di selezione degli utenti messe in atto dagli stessi progetti.
Da questi due aspetti sono emersi dati particolarmente interessanti, perché permettono di evidenziare alcune peculiarità distintive di ciascun progetto facendo
emergere le differenze che li contraddistinguono l’uno dall’altro proprio in ambito di concezione di orientamento e di sue funzioni anche educative e formazione
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
