The hidden turning points of the Mediterranean diet: a tool for health and agro-food policies. Rating out of fifty years, and 22 countries
No full textThe purpose of this study is to develop a method to identify the radical changes in the Mediterranean adequacy index (MAI) trend for monitoring and modifying food and prevention policies. The development of a statistical solver demonstrates that the evolution of the MAI over time (1961-2013) in the EU countries, the USA and Japan is at least bi-parted. In most countries, often two successive conflicting tendencies emerge, whose intersection is signaled by a turning point. The framework of the “knowledge-based view” can help determine whether or not the slopes of the new trend are idiosyncratic with WHO objectives to prevent chronic diseases. Sustainably fighting against the rise in coronary heart disease (CHD) requires to incentive both demand and supply of food products Mediterranean-intensive, revealing by solver use the MAI hidden turning-points . This study allows policymakers to improve their planning, prevention and monitoring capabilities through more exact projections concerning both Mediterranean food markets and emerging CHD risks
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
FRAMMENTI DI PAESAGGIO CULTURALE: I RUDERI DI GIBELLINA
No full textThe present contribution intends to propose an epistemological reflection on the links
relationships that interweave the map, cultural heritage, landscape, and places. We have
indentified an interpretative horizon that intersects the scientific geographic debate with the
literary subject and we have proposed a specific reading of the site of Old Gibellina, in Sicily,
where reality and representation seem to converge. In 1968 Gibellina was razed to the ground
by a seism. The artist Alberto Burri covered the ruins with the concrete realising the “Grande
Cretto”. In our perspective, the Cretto represents a unique place: it is a full size map, it is
landscape, it is world at the same time. What happens then when reality and representation
coincide in a place
Città bianca
No full textDal singolare rapporto tra Mediterraneo e bianco nasce un’indagine sulla genesi delle forme e dei colori del mare nostrum, una sedimentazione di vari studi e ricerche, riordinati in un racconto. La città bianca è il mosaico paesaggistico-culturale del mediterraneo. Come le città invisibili di Marco Polo, il Mediterraneo è una città che è tutte le città: bianca, come una identità inafferrabile, allo stesso tempo locale e universale, nella quale chiunque può ricercare la propria appartenenza
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
Places of ancient agrarian culture : the discovery of a grain pit
No full textThe recovery of memory as well as the protection, preservation, conservation and enhancement of the cultural heritage of our territory – both material and immaterial – are the
starting points for this multidisciplinary research, which aims to recount a history that has almost been forgotten. We refer to the tradition of agrarian culture, and to the ancient
production, commercialization and conservation of wheat: a valuable asset of sustenance for the community that, in centuries past, played a fundamental role for the socio-economic
development of our country, particularly for cities overlooking the Mediterranean basin. Several methods and places have been used to store wheat. This study focuses on the Grain Pit present along the southern Sicilian coast and has allowed us to identify – a few kilometers from Agrigento in the city of Porto Empedocle – a pit that was unknown until now. The hope is
that an unexplored source of tourism can be activated in the future that connects, along various paths, the Grain Pit of the Agrigento area to the great historical, artistic, cultural and
landscape heritage of Sicily
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
