Circularity in the pasta supply chain: Developing a multi-indicator framework for circular economy assessment
The shift towards circular production patterns in the agri-food supply chain is becoming increasingly essential for sustainable development. In this scenario, measuring circularity is critical for ensuring an effective and efficient transition towards such development. Given its relevance, the scientific community and standard-setting bodies are progressively focusing on identifying appropriate circularity indicators. Accordingly, most existing studies have provided broad overviews of available indicators, systematically reviewing academic and grey literature in the context of the agri-food supply chain. Considering the peculiarities of each supply chain within this sector, it is crucial to identify specific indicators in line with their characteristics, providing a practical guide for companies committed to the circular transition. However, a significant gap in research focused on identifying specific indicators for different agri-food supply chain has emerged. To fill this gap, the present research aims to provide a comprehensive framework to measure circularity within the pasta supply chain, representing an essential sector of the worldwide economy. To achieve this, a structured approach was adopted that integrates a systematic literature review with an assessment of the available standards on circular economy measurement. By implementing a rigorous selection process, a final set of 51 indicators - reclassified according to the analytical framework developed in the study - was identified for each pasta supply chain phase. Results show that most indicators could be transversally applied to the PSC. This multi-indicator framework could represent a helpful tool for the pasta industry to measure, monitor and disclose circularity performance in line with the ISO 59020:2024 standard
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
