La lingua come dimora: dall'interiorità individuale al mondo
No full textIn this essay we propose some reflections on the similitude between home and language. In the contemporary world everyone needs an integrated linguistic competence which includes one's own mother tongue (even if it is a dialect) and one or more foreign languages: it is like a house with different floors where we can develop the various aspects of our personal and social life

No full textSeaports experienced extraordinary transformations in recent decades, passing from being transit points between land and sea routes to platforms of modern, now globalized, logistics chains. Such a change led to significant moves in port studies which looked at first unable to grasp what was going on and then followed different paths. I aim to provide a concise tool to account for the basic course of the literature. My hypothesis is that a multiple typology built on criteria at the core of any research design may well account for the diversity and complexity of the field
Numerical analysis of performances of stress grading cable accessories made of different anisotropic composite materials
No full textStress control tubes made out of composite materials characterized by nonlinear and anisotropic electric properties, are widely adopted for the realization of cable accessories, in order to achieve an efficient stress control. In this paper a numerical model, able to take into account both anisotropy and nonlinearity of stress grading composites, will be used to investigate on the effect of the different properties on the field distribution inside cable terminations

MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Analysis of Soft Synchronous Commutations in Switching Converters
No full textIn this paper a new method for the analysis of soft synchronous commutations in switching converters is presented. The method is based on the application of the compensation principle, and allows one to perform jointly the analysis of both hard and soft synchronous commutations. In the paper it is also shown that the proposed method enables one to highlight and explain some mechanisms, underlying soft synchronous commutations, that have not yet been evidenced in literature. In particular, it is shown that a soft commutation of a switching device can trigger the synchronous commutation of other switching devices, provided that proper conditions are met. For the analysis of such situations the derivatives of the currents and of the voltages of switching devices need to be watched. An example concerning the analysis of a ZCT dc-dc switching converter is discusse
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
