Flat dilatometer (DMT). Applications and recent developments
No full textSince the original basic paper on the flat dilatometer (Marchetti 1980) a large number of papers, including manuals and standards, have been published. Aims of this paper are: (a) to briefly describe this in situ test; (b) to summarize the essential related content available in the literature; (c) to give an overview of its main applications; (d) to give information on the most recent developments, thereby permitting the unfamiliar reader to gain in a short time a basic knowledge of the DMT
Three new hybrids of Ophioglossum (Ophioglossaceae) from Monte Pisano (Tuscany, Central Italy)
No full textBased on general morphology, spore measurements and ornamentation (scanning electron microscope), genome size estimation, and molecular systematics (trnL-trnF IGS), we show the extreme systematic complexity within the European representatives of the genus Ophioglossum. In particular, three hybrids from Tuscany are described: the tetraploid O. × pierinii Peruzzi, Magrini, Marchetti & Viane, seen as the hybrid between diploid O. lusitanicum L. and hexaploid O. azoricum C.Presl; the tetraploid O. × giovanninii Peruzzi, Pierini, Magrini, Marchetti & Viane, seen as the homoploid hybrid between tetraploid O. vulgatum L. and tetraploid O. × pierinii Peruzzi, Magrini, Marchetti & Viane; the pentaploid O. × pseudoazoricum Peruzzi, Pierini, Magrini, Marchetti & Viane, seen as the hybrid between hexaploid O. azoricum C.Presl and tetraploid O. vulgatum L. All the three new taxa grow in different localities in the Monte Pisano mountain range
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
Omaggio a Bruno Ciari, maestro
No full textIl saggio ricostruisce il pensiero educativo e la didattica di Bruno Ciari alla luce dell'influenza di Dewey e di Marx. Bruno Ciari,uno dei padri nobili della pedagogia italiana,visse nel periodo fascista,di umili origini, rinnego' il regime e si uni' alla resistenza. Da vero maestro motivo' i suoi giovani e, attraverso metodi anticonvenzionali come il gioco,l'animazione ,il canto e le esplorazioni,li condusse alla liberta' del pensiero.La sua scuola, intesa come "laboratorio di idee",non fu quella del voto-condanna e della gara,quella della discriminazione del diverso e del debole ma quella della raffinata differenziazioni delle intelligenze.Fondo' il Movimento di cooperazione educativa tutt'oggi in uso da pedagogisti,insegnanti e psicoanalisti. Il saggio vuole aprire una riflessione profonda e significativa intorno alla didattica attiva, proponendo nuovi modi di insegnare

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
