Carne, latte e cereali: dalla comunicazione del prodotto alla comunicazione nel prodotto
No full textIl saggio presenta un progetto di ricerca realizzato dal Center for Generative Communication (CfGC) in collaborazione con il Dipartimento di Gestione dei Sistemi Agrari, Alimentari e Forestali (GESAAF) e con le aziende dell’Associazione Produttori Biologici del Mugello. Rispondendo al bando multifiliera della Regione Toscana previsto per il PSR 2014-2020, scopo delle attività del Center for Generative Communication è quello di realizzare un “Marchio collettivo territoriale biologico Mugello” che valorizzi e promuova i prodotti agricoli biologici, attraverso accordi tra produttori che ne regolino scambi e relazioni.
I ricercatori sono stati chiamati a sviluppare un processo partecipativo, in linea con quanto promosso dal paradigma della comunicazione generativa, che portasse alla realizzazione del logo del Marchio Territoriale Collettivo, attraverso una serie di azioni comunicative finalizzate a far incontrare e dialogare i diversi portatori d’interesse chiamati in causa
How to detect illegal waste shipments? The case of the international trade in polyethylene waste
Full text linkThe purpose of this research is to provide a methodological framework that is able to enhance our capability to detect
illegal waste shipment with particular reference to waste plastics. Based on a very large cross-sectional dataset
covering 187 countries over the period 2002-2012, our study aims to do this by using both the mirror statistics method
and the network analysis. Specifically, by using mirror statistics, we identify the existence of a set of “suspicious”
trade relations between pairs of countries. Then, we employ social network analysis in order to define the position of
each country in this illegal trade structure, and to have a clear exposition of the connections between them. Our main
findings reveal the central positions of the USA, Germany and the UK as sources and China and Malaysia as outlets of
illegal shipments of waste plastics. Moreover, our methodology allows us to highlight the presence of other countries,
which carry out an intermediary role within the global trade network, and to detect the changes in traditional illegal
shipment routes. Therefore, this paper shows how social network analysis provides a useful instrument by means of
which crime analysts and police detectives can develop effective strategies to interdict criminal activities
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
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
Perspectives on salvage therapy for non-small-cell lung cancer
No full text: Platinum-based chemotherapy offers a modest survival advantage over best supportive care in chemotherapy-naive patients with a good performance status and advanced/metastatic non-small-cell lung cancer (NSCLC). Despite the survival benefit associated with first-line chemotherapy, the majority of patients will experience relapse or disease progression. In clinicalpractice, an increasing number of patients maintain a good performance status after first-line treatment and are eligible for further treatments. Docetaxel (Taxotere) at 75 mg/m2 given once every 3 weeks has been the standard of care for second-line chemotherapy since the year 2000. Pemetrexed (Alimta) is a novel multitargeted antifolate agent with single-agent activity in first- and second-line treatment of NSCLC. A large phase 111 study comparing docetaxel to pemetrexed in second-line therapy demonstrated that pemetrexed is equally active and less toxic than docetaxel. Based on these results, pemetrexed is a reasonable second-line chemotherapy option for patients with recurrent, advanced NSCLC. Progress made in the field of molecular biology has led to the identification of drugs active against specific cellular targets. Gefitinib (Iressa) and erlotinib (Tarceva) are both orally active tyrosine kinase inhibitors of the epidermal growth factor receptor. Phase II and III trials have demonstrated that these agents are active particularly in a subgroup of patients with specific biologic characteristics. Both drugs have been approved for the treatment of pretreated NSCLC. Other drugs, such as cetuximab (Erbitux) and bevacizumab (Avastin) have shown promising activity in NSCLC and are currently being tested in clinical trials
