Circular Economy in the agri-food sector: a policy overview
No full textAgri-food is the second manufacturing sector in Italy, due to its strategic nature. However,it is affected by several problematics, and one of the most severe is the generation of wastes and by-products. The circular economy could be a winning approach to improve the sustainability of the food supply chain. The objective of this paper is to provide an overview of the current policy situation in Europe, with a focus on Italy. The history of circular economy policies in Europe started recently, and is continuing nowadays with the New Circular Economy Action Plan. Italy is in the top position for circularity, even if it has not yet implemented a proper circular economy policy. Future actions should concentrate on developing innovative circular models for the agri-food sector
Circular economy for a sustainable agri-food supply chain: A review for current trends and future pathways
Full text linkThe current agri-food supply chain is affected by different problems such as food loss and waste generation along the supply chain, and the circular economy offers a possibility to enhance and optimize the production and consumption to seek to a sustainable paradigm. The circular economy can be a winning approach to intervene and moderate the impacts generated in the agri-food sector, proposing actions and solutions to readmit wastes and by-products in the productive chain. The aim of this work was to perform a literature review coupled with a bibliometric analysis, using VOSviewer software, on the circular economy model in the agri-food sector, with particular relevance to the reuse and valorisation of wastes and by-products. Results showed that the topic is of particular relevance in the scientific community, and the concept is continuously evolving. Europe plays a leading role in the research, thanks to the involvement of the Member States, policy makers and stakeholders. Nevertheless, some aspects such as the development of a new economic circular model and some limitations of the current policies deserve further investigation
Understanding consumption choices of innovative products: an outlook on the Italian functional food market
No full textNowadays, the interest towards functional food has increased; however, several factors jeopardize their diffusion on the market. In fact, functional foods do not have either a specific regulatory framework or a statutory definition in Europe. A functional food with any nutrition and health claim related to vitamins, minerals, or other substances in their labeling have to meet only the specific requirements established by the Regulation (EC) 1924/2006. Consequently, these products are not uniquely recognizable and the perception of consumers towards them remains a confusing concept. In this scenario, this paper investigates knowledge and factors affecting consumers‟ consumption intention towards functional food in Italy. For this purpose, a survey was designed, and a logit model was used to explain motivators for the consumption of functional products. The result indicates that consumers are still confused about the concept of functional foods. An important motive for the consumption of functional food is the maintenance of good nutrition, health conditions as well as well-being. An additional factor in the success of functional products is the familiarity and the knowledge of the effects of a particular product on health conditions. The probability of the consumption of a functional product increases when the consumer associates the knows of the functional characteristic and the healthful properties with the consequences of their consumption. Results are useful to verify the opportunities for further expansion of these products on the Italian market
Advanced Training in Precision Farming: The Italian On-Farm Pilot Experimentation of the BOOST Project
Full text linkThis paper presents the first Italian case study of a participatory training course in agribusiness and precision farming, implemented on-farm with the BOOST Project method. The study adopts Yin’s case study methodology to investigate this innovative approach, focusing on peer-to-peer learning and mentorship as systemic solutions to the persistent training gap in farm technological management. Results, which are preliminary and longitudinal in nature, suggest that project-based education may significantly enhance effective technology adoption in agriculture. © 2025 Greek Association of Agricultural Economists.

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
