Collaborations for circular food waste management in Italian fish manufacturing firms: A resource dependence perspective
Get PDFThis paper aims to shed light on supply chain collaborations in circular economy for food waste prevention and management. The exploratory study adopts a multiple case study research design on a sample of two polar cases: a small enterprise and a large company in the Italian manufacturing industry of fishery products. Resource Dependence Theory (RDT) allows for an understanding of the mechanisms of circular supply chains, describing strategic motivators of collaborations for circular economy, and overall provides a novel perspective on food waste prevention and management. This study highlights how companies develop in-house solutions when the food waste streams are moderate but rely on collaborations when the streams are conspicuous, thus, the need to implement circular economy solutions fosters collaborations. The findings provide a novel perspective on collaborations in circular economy; furthermore, RDT offers a novel conceptualization of food waste management practices, highlighting the suitability of further applying RDT to this field of study
A systematic review of research on food loss and waste prevention and management for the circular economy
Get PDFCircular Economy (CE) aims to retain the maximum value of products and materials for a longer time in a closed-loop manner, thereby decoupling natural resource usage from economic growth. Food waste reduction is one of the top priorities under the recent European Union's CE Package. It also contributes to achieving the United Nations' Sustainable Development Goals (SDG 12.3). While food loss and waste (FLW) prevention and management are well-studied in the literature, research in CE is more recent. Through a systematic literature review, this study creates a taxonomy that synthesises the key aspects of FLW under the CE. 297 papers were reviewed and analysed using keyword co-occurrence analysis (KCN) and structural dimension analysis. In KCN, three research themes emerge: impact assessment, biorefinery, and nutrient recycling. Structural dimension analysis reveals the types of research methods, types of FLW flows, FLW prevention and management options with associated opportunities and challenges, and the sustainability impact assessment (SIA) addressed in the literature. A taxonomy is presented and future research directions are highlighted under six research streams: i) FLW supply and quantification, ii) practices and technological aspects, iii) logistics and supply chain management, iv) market demand, v) SIA, and vi) policy and legislation. Combining insights from CE and FLW prevention and management, the taxonomy helps key stakeholders, including industry practitioners to grasp new business opportunities, politicians to set up support strategies and strategic development plans, society to recognise the benefits of waste-oriented bioeconomy, and consumers to raise their awareness and be actively involved in CE
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
