Populonia. Il territorio di Populonia fra il periodo etrusco tardo e il periodo romano. La ricognizione archeologica
No full textTra il monte Amiata e la Valle del Paglia. La natura polisemica di un paesaggio marginale
No full textThe context of the Paglia valley has been, on and off, relegated to an improper condition of marginality. In this contribution we summarise the results of previous research projects carried out in Abbadia San Salvatore and Radicofani. The centrality of the mountain during the Bronze Age, attested by conspicuous archaeological sites, was followed by a period of long silence, partly effective and partly explainable by the difficulty in finding, reading and interpreting certain particular types of sources. In reality, both the mountain and the valley occupied a central visual and semantic role in the perception of ancient communities and their ideational landscape. The valley bottom road, a non-secondary diverticulum of the Via Cassia, played a central role in the vertical mobility and exchanges in the Roman period, especially from the imperial age onwards and well before the history of the Via Francigena/Romea began.
Villages and rural agglomerations on the valley bottom, integrated in a coherent network that forms the true ecological-historical interface between this border area and the Tiber valley, are the key to interpret the history of the context, a history of long duration but marked by sometimes sudden and deep transformations
Il progetto Aladin: un agroalimentare idro intelligente contro l’approccio settoriale al risparmio idrico
Get PDFIl progetto ALADIN punta a raggiungere concreti avanzamenti nell’irrigazione ottimale delle colture intensive, in particolare su mais e pomodoro, con una sperimentazione biennale che supera i vecchi approcci settoriali. Essa è basata sulla messa a sistema di tutte le componenti che intervengono nella valutazione dell’esigenza idrica e nelle pratiche irrigue, e sull’integrazione nel collaudato sistema IrriNet del CER, che indica quando e quanto irrigare, per scendere al dettaglio delle parti diversamente idroesigenti all’interno di un singolo appezzamento.
Il raggruppamento ALADIN è composto da: CIDEA Università di Parma, Terra & Acqua Tech Università di Ferrara; CER Bologna, CRPA LAB Reggio Emilia, SSICA Parma, DipSA Università di Bologna, ARPAE Idro-Meteo-Clima Bologna e Azienda Sperimentale Stuard Parma e dalle imprese: AeroDron Parma, Sacmi Imola, RM Irrigation Equipment Parma e Tomato Colors Bologna
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
Get PDFThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
Performance Measurement and Management: What is Next?
No full textThe paper reviews the literature in the field of performance measurement and management (PMM) for small and medium enterprises (SMEs) and large companies. The methodology adopted for reviewing the literature relies on the citation/co-citation analysis of research on PMM and on the analysis of the frameworks/models developed in the last twenty years both for large and SMEs. The evolution of the research field is discussed and future areas of research are identified. The results of the literature review carried out reveal a certain maturity of the literature related to large companies and a significant lack of PMM literature for SMEs
