Economic analysis of the traditional cultural vineyard landscapes in Italy
International audienceThe Traditional Cultural Landscapes (TCLs) have been studied from different points of view since the pioneering work of Antrop (1997). The aim of this study is to analyze the TCLs from a bottom-up perspective, focussing on the internal organization of a number of farms and looking at technical and economical characteristics, and also at social and cultural aspects. The focus is on Traditional Cultural Vineyard Landscape (TCVL) because the viticulture sector is the one most integrated with the kind of tourism that is interested in quality food products associated with a specific place of origin, and also the sector that, more than others, has responded to market changes by increasing the appeal of their products. Accordingly, the economic performance of three Italian winemaking farms was analyzed by means of cost-based method to explore: the cost of restoring a TCVL; the cost of producing the grape and the wine; the economic profitability of the investment in the TCVL; the relationship between entrepreneurial strategies and the use of landscape in a functional perspective. The positive financial results achieved by these farms in different part of Italy suggest that the financial success or failure of an investment in landscape is not determined by the socio-economic context but by the ability of the farm to differentiate its product, gaining a competitive advantage by offering customers greater value. The key issue is not the contrast between those who support the costs of landscape preservation (vineyard owners) and those who reap its benefits (the community as a whole), but rather in the way in which the added value resulting from preservation of the landscape is being obtained and distributed. The results demonstrates that landscape preservation can be a driving force for improvements in farm management and farm income but it is still necessary enlarge the duty to contribute to their preservation improving government measures for the restoration and preservation of the TCLs, and consumer awareness about the importance of products from these areas with TCLs
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
De la ville qui mange à la ville qui produit: l'exemple des Horteloes Urbanos de Sao Paulo
International audienceCet article focalise l’attention sur des formes d’agriculture novatrices qui sont celles de l’agriculture urbaine (AU), en particulier les jardins partagés. Il s’agit d’investiguer à la fois les modèles de production en ville et les modes deconsommation complémentaires ou alternatifs au modèle dominant. Les jardins partagés sont effectivement en train de se répandre dans la majorité des villes. Cultiver en ville n’est pas un phénomène récent; mais par rapport au passé, les motivations des acteurs ainsi que les politiques mises en place pour la promotion de jardins dans les espaces intra et périurbains diffèrent. J’approfondirai l’hypothèse que les inquiétudes ou les désirs des acteurs en relation avec la façon de produire et de consommer les aliments et d’habiter la ville, sont à l’origine des jardins partagés contemporains.Ces espaces sont des éléments multifonctionnels de la ville, qui produisent de nouvelles relations entre les acteurs et de nouvelles pratiques agro-alimentaires et qui donnent lieu à des nouvelles formes d’identités individuelles et collectives

Dispelling the Myths Behind First-author Citation Counts
We 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
