No full textSEeD for Change: The Systemic Event Design Project Applied to Terra Madre Salone del Gusto for the Development of Food Communities
Full text linkIn the contemporary era, food plays a key role in balancing environmental, social, and economic balances, not only due to its primary identity as a resource that nourishes living beings and the planet but also through the processes triggered by stakeholders who act at the internal local food systems. In the latter, an orientation towards sustainability is increasingly urgently required, capable of achieving a widespread creation of shared value. In this scenario, the International Slow Food Association operates, which also, through the Terra Madre Salone del Gusto initiative, coordinates communities and events located throughout the world on the theme of “good, clean and fair” food. This article aims to analyze, through the lens of the systemic approach, the interesting and multifaceted impacts of this event, as an opportunity to disseminate and contagion of ideas, attitudes, and behaviors around the themes of sustainability and biodiversity, but also as a moment of consolidation and creation of relationships between and within local food systems and local communities. The research project presented, entitled “SEeD for Change”, was coordinated by the University of Gastronomic Sciences of Pollenzo with the University of Turin and helped to focus on the actors, relationships and contexts that actually and virtually hosted the event: places in which through a common and shared language, change has been generated
Sustainability policies adoption within Italian Michelin-starred restaurants: From external drivers to costs
Full text linkThe purpose of the research is to investigate the increasing importance of the role of sustainability in high-end restaurants, specifically in those awarded Michelin stars. The focus is on the role sustainability plays as a crucial element in the state-of-the-art of fine-dining business given that restaurants are challenged to reconsider the noteworthiness of new sustainable imperatives. The study is based on a questionnaire survey carried out with over 70 owners and chefs from Italian Michelin-starred restaurants. The results show a clear tendency towards sustainability and an increasing attention towards this trend, emphasizing its peculiarities for the restaurant industry, which is indicates profound changes. More specifically, 35% of the variance in internal sustainability policies adoption is explained by external drives related to sustainability and customers' demands of sustainability. The data collected relies on an Italian sample, but the results are useful to understand the sustainability imperatives for the Michelin-stars restaurants worldwide as the Italian food service industry is often deemed as iconic. The study advances new insights into the future of the sustainable restaurant industry. The results of research are based on a novel research design and empirical survey capturing the state-of-the-art of sustainability policies adoption in the case of Michelin-starred restaurants
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
