The effects of unions on wage inequality. The Italian case in the nineties
No full textIn this paper we analyse the contribution of union activity to reducing earnings inequality. Given the specific nature of the system of industrial relations, Italian unions may contribute to inequality reduction through either national bargaining (i.e. reducing between-sector differentials) and/or local bargaining (i.e. reducing within-establishment inequality). After reviewing aggregate evidence on the first dimension, we explore the second route making use of matched employer-employees data-set, surveyed in 1995 by Eurostat. We pay great care to the potential endogeneity of local bargaining, and we find that the widespread adoption of local bargaining, by reducing the implicit price of individual characteristics, effectively contributes to inequality reduction

The Market for Paintings in Italy During the Seventeenth Century
Full text linkWe study the seventeenth-century market for figurative paintings in Italy analyzing original contracts between patrons and artists. We show that a number of supply and demand factors affected prices. We find a positive and concave relation between prices and size of paintings reflecting economies of scale. We show evidence of a positive relationship between prices and the number of figures depicted. Trade in paintings was sufficient to equalize prices between different destinations. Finally, we provide support for the Galenson hypothesis
of a positive relation between age of experimental artists and quality as priced by the market
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
Lexicon of Greek Grammarians of Antiquity (LGGA)
No full textEncyclopedic reference work in progress, including articles on ancient Greek personalities and writers known for scholarly activity and works. The database is expected to include near 580 articles in the end. The project started as "Lessico dei Grammatici Greci Antichi" and was initially funded by PRIN (University of Genoa)
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
Active neutron detector for direct Dark Matter searches with the DarkSide-50 experiment at Gran Sasso
No full textThe existence of dark matter is known from gravitational effects, and although its nature remains undisclosed, there is a growing indication that the galactic halo could be permeated by WIMPs with mass of the order of 100 GeV. Direct observation of WIMP-nuclear collisions in a laboratory detector plays a key role in dark matter searches. However, it also poses significant challenges, as the expected signals are low in energy and very rare.
DarkSide is a project for direct observation of WIMPs in a liquid argon time-projection chamber that can meet these challenges. A limiting background for all dark matter detectors is the production in their active volumes of nuclear recoils from the elastic scattering of neutrons. DarkSide-50 is surrounded by a liquid scintillator, doped with Boron, which is used as an active high-efficiency
neutron detector. In order to acquire the PMT signal we have developed custom front-end amplifiers with built-in trigger capabilities and a DAQ system based on high-resolution fast digitizers
