Navigating Food Transition: European Policy Tools for Novel Foods and the Italian Debate on Cultured Meat
No full textThe global food system—encompassing production, consumption, and disposal—has been widely recognized as unsustainable, contributing significantly to environmental degradation and social disparities. In response to these challenges, the transition toward more equitable food systems has become imperative. Despite the widely acknowledged need to change Western eating habits, the transition toward more sustainable diets appears as a “false wicked problem” being characterized by intricate trade-offs between economic, ethical, societal, and environmental issues. This paper examines the crucial role of policy interventions in steering the shift and in considering the role that the emergence of novel foods and alternative proteins – such as cultured meat – might play within it. By employing a qualitative methodology, the study maps the policies governing novel foods in Europe, with a specific emphasis on the three tools of regulations, informational campaigns, and incentives. This paper gives particular attention to the cultured meat debate in Italy as a case study for approaching not only the multifaceted nature of food—an interplay of cultural values, economic interests, and political decision-making—but also the staunch resistance that such transition is likely to encounter. The main highlights underscore the need for a comprehensive and balanced approach to integrate regulatory measures, consumer education, and inclusive stakeholder engagement while stressing the importance of evidence-based choices, transparent communication, and the recognition of the socio-cultural dimensions in shaping food policies
The Importance of Region of Origin in Sparkling Wines: An International Analysis of Consumers’ Perception
No full textConsumers’ perception of the region of origin represents a critical issue for building a valuable and sustainable business in the wine sector. The aim of this study is to investigate the role of the region of origin in Italian sparkling wines, comparing consumers’ perception of emerging wines with a designation of origin in regions not traditionally associated with sparkling wine production (Abruzzo and Romagna), with an affirmed brand (Prosecco) and with generic Italian sparkling wine. The three most important markets for Italian sparkling wines (Italy, the USA, and the UK) are considered. The importance of the region of origin is analyzed within a set of wine attributes, including color and sugar content, applying the conjoint analysis technique to simulate realistic market conditions, offering multiple options for wine attributes. There is no cumulative effect of the perception of wines with a Protected Designation of Origin in the three markets since consumers who positively perceive a specific designation do not extend this positive perception to others in comparison with generic sparkling wine. Positive and negative utilities associated with each designation of origin are calculated and used to discriminate consumers according to socio-demographic variables, consumers’ behavior, and attitudes
L’agroalimentare abruzzese tra crisi e crescita. Rapporto 2013 sul Sistema Agroalimentare Abruzzese
No full textIl presente Rapporto è stato elaborato nell’ambito del progetto per la costi-tuzione di un “Osservatorio sul sistema agroalimentare regionale”, pro-mosso dal consorzio Agire, soggetto gestore del Polo di innovazione agroalimentare d’Abruzzo.
E’ stato curato dai ricercatori del gruppo di ricerca di economia e marke-ting agroalimentare della Facoltà di Bioscienze e Tecnologie Agro-Alimentari ed Ambientali dell’Università degli studi di Teramo e dell’INEA (Istituto Nazionale di Economia Agraria), sede regionale per l'Abruzzo, in collaborazione con il CRESA (Centro Regionale di Studi e Ricerche Economico Sociali) e con la partecipazione di studiosi di econo-mia agraria ed ingegneria economico-gestionale delle Università abruzzesi
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
