Cultura Normativa e Ausili per Disabili:
esperienze, risultati e prospettive
PREMESSA
Questo documento viene redatto in seno al progetto “Cultura e rappresentanza normativa”, della
Camera di Commercio di Padova.
Esso rappresenta la sintesi del lavoro di un lavoro avviato nel 2008 con il supporto della Camera di
Commercio di Padova e della CNA di Padova, in collaborazione prima con il Dipartimento di Inge-
gneria Meccanica ed ora con il Dipartimento di Ingegneria Industriale dell'Università di Padova,
con l'obiettivo di coinvolgere i produttori di ausili del territorio e di rinnovare l'attenzione e la parteci-
pazione ai lavori di normazione in atto a livello internazionale.
Le imprese del settore hanno avuto la possibilità di essere presenti nelle discussioni tecniche, di te-
stare i propri ausili con le attrezzature e le metodologie sviluppate presso il Dipartimento
dell'Università di Padova, di essere propositive nelle soluzioni di prova e di conseguenza reattive
nel mercato conoscendo in anticipo le modalità di prova ed i requisiti di sicurezza
A filtration system for the size separation of fresh water samples
No full textA system to filter freshwater samples in situ in the field is described, using polycarbonate membranes. It was developed and tested with respect to the conventional filtration method, both for its efficiency and for the effect on for its efficiency and for the effect on heavy metal concentrations in the filtrates. A marked reduction of filtration time is obtained and the possibility to carry out one stage filtrations that otherwise would need the filter to be changed. PIXE analysis generally shows an increase of heavy metal concentrations in the filtrates; this is accompanied by a smaller data spread in sub-samples obtained by repeated filtrations, indicating a higher capability in maintaining the nominal membrane pore size during operations, which produces a better dimensional selection. The system is suitable to perform immediate filtration of numerous fresh water samples to be treated in heavy metal pollution assessments

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
