Deconstruction of the Corso Grosseto viaduct and setup of a testing site for full scale load tests
No full textBRIDGE|50 is a research project recently launched in Italy in the context of the Torino-Ceres construction works jointly with Politecnico di Milano, Politecnico di Torino, public authorities and private companies. The aim of the BRIDGE|50 research project is to investigate the residual structural performance of the Corso Grosseto 50-year-old prestressed concrete bridge through an experimental campaign. The dismantling and demolition procedures of Corso Grosseto viaduct are presented in this paper, including the setup of the field laboratory where several deck beams and pier caps will be tested up to collapse

Scavi e ricerche archeologiche ad Albinia (Grosseto)
No full textGli scavi da noi diretti con la missione italiana a Bibracte, nella città celtica degli Edui, il popolo più amico dei romani, hanno dato origine a un progetto di ricerca legato al tema del vino e del commercio del vino etrusco-italico in area gallica. Il sito identificato per indagare un centro di produzione di anfore al servizio della produzione viticola e della commercializzazione del vino è quello di Albinia, allo sbocco dell'Albegna nel Tirreno, in provincia di Grosseto.
Il centro antico di Albinia ha rivelato potenzialità enormi, tali da attivare una ricerca ex 40% sul tema del vino, coordinata a livello nazionale dallo scrivente.
Si sono individuati 8 impianti a fornaci, di diverse dimensioni, destinati alla produzione di anfore, laterizi e vasellame di piccole e medie dimensioni. Lo scavo ha interessato un'area di 2.500 mq.
La ricerca si muove in un ambito internazionale collegata a specialisti del CNRS sul tema delle anfore romane (UMR 7710 ARSCAN, Nanterre)
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
"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.
Scavi e ricerche archeologiche ad Albinia (Grosseto)
No full textLa ricerca ha associato, mediante una convenzione specifica, anche l'Università di Siena - sede di Grosseto (dott.ssa Silvia Pallecchi). Rimangono le collaborazioni internazionali francesi (CNRS, Fanette laubenheimer; INRAP, Laurence Benquet).
I risultati dello scavo che aumenta in estensione e in profondità a vista d'occhio ( quasi 5.000 mq splateati) hanno mostrato la successione nel tempo di quattro fornaci rettangolari e di altre quattro fornaci identiche in sovrapposizione verticale alle quattro precedenti. L'area viene demolita e spianata nell'antichità e due nuovo fornaci vengono create su due delle quattro iniziali: in totale 4 + 4+ 2 = 10 grandi fornaci destinate a cuocere anfore. Di queste ultime si sono caratterizzate le forme che si sono succedute nell'arco di due secoli e mezzo: le csd greco-italiche, le Dressel 1 A, B, C, le Dressel 2/4, le anfore a fondo piatto di varie fogge e dimensioni.
E' anche stato individuato un bollo laterizio (VOLVS) che dovrebbe corrispondere al nome di un fabbricante di tegole romane proprio ad Albinia. Il commercio di queste tegole ha interessato la costa tirrenica settentrionale fino a Luni. Si deve infine parlare di un importantissimo drenaggio o vuoto sanitario fatto con centinaia di anfore quasi intere ma con difetti di cottura. Tale drenaggio fu reso necessario per la situazione di sommersione dell'atelier, che venne rialzato nelle fornaci e nelle arre antistanti proprio con potenti riporti di anfore/terra o con piattaforme ad anfore come quella di cui parliamo. Anche questa scoperta è unica per numero e tipologia dei materiali impiegati
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
