Growth and institutions in Paolo Sylos Labini's thought
Full text linkAccording to Paolo Sylos Labini (1920-2005), it is vital for an economist to be acutely conscious of the responsibility to study society for the sake of promoting progress—the economic, social and civil progress of society—and not for personal interest. In his last book, Ahi serva Italia (2006), Sylos Labini spoke as a civic-minded economist to all those Italians who refuse to understand that respect for the rules is an absolute requirement for a market economy, and, in particular, that a market economy needs rules to defend the community against the unbridled expansion of positions of power. Within this analytical framework, our paper aims to discuss the role of institutions along different lines: the role of the market in the process of economic growth, public intervention in the economy and the process of institutional innovations
Il dialogo di civiltà alla luce dell’esperienza kazakistana
Full text linkLa Repubblica del Kazakhstan, che ha acquisito l’indipendenza nel 1991 in seguito alla dissoluzione dell’URSS, è uno dei Paesi più variegati del mondo sotto il profilo della composizione nazionale e religiosa: sul suo vasto territorio si contano infatti oltre 130 gruppi etnici e 40 confessioni all’interno di una popolazione di circa 16 milioni di abitanti. Una realtà che si potrebbe definire tanto complessa quanto poco conosciuta, specialmente in Italia. Il testo si concentra sulla strategia perseguita dal governo kazako (la c.d. unità nella diversità, o in alcuni
documenti l’unità attraverso la diversità), che a partire dall’indipendenza si è trovato a governare in piena autonomia su una realtà estremamente eterogenea. La scelta delle autorità è stata quella di puntare sulla costruzione di una identità “kazakistana”, ossia civile, laica e sovranazionale, che ambisce a garantire una convivenza pacifica proponendosi come modello di dialogo fra civiltà. La distinzione tra identità “kazaka” (cioè etnicamente e linguisticamente connotata) e identità “kazakistana” (chiamata ad accogliere popoli diversi sotto una cittadinanza esplicitamente multiculturale) costituisce il cuore di questa strategia
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

The Role of counterions (Mo, Nb, Sb, W) in Cr-, Mn-, Ni- and V-doped rutile ceramic pigments. Part 2. Colour and technological properties
Full text linkIndustrial rutile pigments are manufactured using several chromophores: Cr (giving an orange hue), Mn (tan), Ni (yellow) and V (gray); a second element, the so-called counterion (i.e. Mo, Sb, Nb or W) is always added in order to achieve the desired coloration and/or improve the technological properties (e.g. chemico-physical resistance in ceramic bodies and glazes). The colour of these pigments is determined by both metal-ligand charge transfer (Ti4+ <-> O2-) and crystal field effects (transition metals substituting Ti4+ in octahedral coordination). Though the absorbance bands are broad and frequently overlapped, the UV-vis-NIR spectra suggest the occurrence of Cr3+, Mn2+, Mn3+, Ni2+, V3+, and V4+ as chromophores. Rutile pigments are suitable for through-body (up to 1250 degrees C) and glaze applications (up to 1100 degrees C). The best coloration of porcelain stoneware bodies is achieved with Sb or W as counterions, though the higher stability is ensured by Sb, but in the Ti-Ni-W system. The best glaze colours are accomplished by W-bearing pigments, which however are less stable than Nb- or Sb-containing ones, except than for the V + W coupling. This latter represents a new and very interesting Co-free and Cr-free black pigment for low temperature applications
