L'Università e il cibo:introduzione a un tavolo di lavoro
No full textQuesto volume prende spunto da un incontro su “Buone pratiche di alimentazione sostenibile nelle Univer- sità”, svoltosi a Torino il 21 settembre 2018 durante l’edizione di Terra Madre Salone del Gusto, nota manife- stazione internazionale, con cadenza biennale, sul cibo e lo sviluppo sostenibile del food system
Le mense universitarie e lo spreco alimentare: alcune riflessioni e possibili soluzioni al problema
No full textIt is well known nowadays that food waste emerges as one of the rare problems that crosses multiple social issues, from food security and environmental degradation to economic efficiency. Wasted food, according to several reports, has to be related with the number of people in the world affected by chronic food deprivation. On the other side, FAO reported that one-third of the edible parts of food produced for human consumption is wasted globally. These high figures give us a general overview of a paradoxical problem that has a tremendous impact worldwide. Numerous studies shed some lights on food waste as a behavioral problem and measured the effectiveness of different initiatives on food waste prevention at school, but, there is limited research about how university canteen customers’ habits affect the level of food waste produced. Starting from these premises this study proposed an overview on a theoretical model, with the aim to explain how the salient values, with regard to eating interplay, affect food consumption behavior and customers’ perceived food waste generation at a university canteen
Strumenti giuridici per l'alimentazione sostenibile nell'Università
No full textRecent data on institutional catering in Italy stren- gthen the role of GPP as an economic policy tool be- cause it is able to reduce the direct environmental im- pact of public activities and to represent an example of environmental awareness, and also because of the possibility of encouraging the integration of environ- mental considerations into other policies (transport, energy, etc..) and to exert pressure on the market to offer goods, services and works with low environmen- tal impact, promoting the development of technolo- gies and production chains, the growth of businesses and green jobs. In the case of the use by universities of GPP for the purchase of food, intended mainly for student canteens, there is also the additional purpo- se of encouraging the student population to adopt conscious choices and lifestyles consistent with the principle of sustainability. The paper focuses on the progressive refinement of European and national le- gislation and on the prospects for the development of regulation
LA PRODUZIONE DI CIBO NELLE AZIENDE AGRARIE SPERIMENTALI DELLE UNIVERSITÀ ITALIANE
No full textItalian university farms provide a crucial support for teaching, research and innovation transfer in the agrofood, forestry, environmental and even social sectors. In order to point out their current values and weaknesses, and to start reflecting on possible development strategies, a survey was realised. The main weaknesses emerged concern the availability of the required data, in particular economic data, and the economic sustainability of these farms, especially with regard to staff costs. Moreover, the survey made it possible to outline for the first time a cognitive framework of the Italian university farms, thus creating a useful database for future updates and insights. The chapter offers also a description of a recent experience of “urban farming” in Udine, the so called “University Vegetable Garden” for for self-production of organic vegetables
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
