Università di Padova e territorio: trasformazioni, sfide e opportunità della città universitaria metropolitana nel contesto veneto University of Padua and its territory: transformations, challenges and opportunities of the Metropolitan University City in the Veneto context
Full text linkThrough the analysis of the enrollment data of the students of the University of Padua and neighboring universities, examined and mapped through GIS technology, in the years 1977-2007-2017-2020, this contribution intends to highlight how the system of the university of North East has evolved and how student mobility in central Veneto and towards the city of Padua has changed over the years. At the same time, a comparison with other regional contexts will make it possible to highlight the difficulty of the Veneto production system in absorbing graduates, this last element helps to explain the greater difficulty for the University of Padua to collaborate with the business world of the territory

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
STEADY-STATE AND STABILITY ANALYSIS OF NATURAL CIRCULATION WITH FLUIDS AT SUPERCRITICAL PRESSURE
No full textNatural circulation of CO 2 at supercritical pressure is addressed
in the present paper in order to assess the capabilities of linear
and nonlinear analysis in-house codes developed for studying
steady-state and transient behaviour of natural circulation
loops. In past activities, the models have been developed,
taking into account also the effect of the presence of heating
structures, and have been equipped with a low diffusion
numerical scheme, in order to minimise truncation error effects.
In the present work, available heat transfer correlations were
introduced in order to properly simulate heat transfer to
supercritical fluids, though the present state-of-the-art in the
field does not yet allow to reliably simulate relevant effects as
the deteriorated of heat transfer occurring when buoyancy
effects become dominant. The obtained transient and linear
stability analysis codes were applied to published experiments
performed at the Bhabha Atomic Research Centre in Mumbai,
India, making use of carbon dioxide as working fluid. Both
steady-state conditions and transient behaviour were addressed,
obtaining interesting data in comparison to experimentally
observed behaviour
