Trends in consumers’ preferences towards fresh-cut vegetables during the Covid-19 pandemic
Full text linkThe fresh-cut sector has shown a positive trend in recent years, due to the “ease of use” and the increasing innovation in the quality and safety features of these products. However, in Italy, a negative trend was observed during the lockdown Covid-19. The objective of this study is to investigate consumer preferences for fresh-cut products and to identify the sensory and extrinsic attributes that influence consumer choice. It also examines whether consumer behaviour has changed during the lockdown Covid-19. An online questionnaire was administered to a convenience sample of 427 consumers. A one-way ANOVA was conducted to identify preferences for specific types of fresh-cut products; then, a factor analysis was conducted to highlight key socioeconomic variables and product attributes. Finally, a cluster analysis was conducted to identify homogeneous consumer groups. The results indicate that some attributes, including “ease of use”, “texture” and “colour” show a high level of interest and appreciation by consumers. The outcomes also reveal that there has been a change in consumer attitudes during the lockdown Covid-19, mainly for reasons related to the difficulty in food procurement, the fear of contagion during purchasing occasion, and higher prices. The findings of this research contribute to the knowledge of consumers’ behaviour towards fresh-cut products in the period of lockdown Covid-19
Circular Economy Models in Agro-Food Systems: A Review
Full text linkAround the world, interest is growing in the circular economy in response to the current unsustainable model of production and consumption based on increased use and depletion of resources. This paper provides a review of the academic literature on the circular economy in agrifood systems, with the aims of understanding its main characteristics and perspectives, and summarizing and discussing the literature in this field. This review provides a deeper understanding of the opportunities provided by the circular economy as a solution to the current need to reduce the environmental impacts of business-as-usual economic systems and the state of the art of the circular economy in the academic debate. The results are discussed based on the chosen topic-core investigated in this review: business model and organization management, food loss and waste along the supply chain, analytical tools for the circular economy, stakeholder acceptance of the circular economy, and mitigation strategies and political approach. The findings show the need for the implementation of cleaner production models and consequent increases in stakeholder responsibilities and awareness, from both producers and consumers, as well as the need for the implementation of suitable policies and tools
Consumers’ Attitudes and Purchase Intention for a Vitamin-Enriched Extra Virgin Olive Oil
No full textThis study aims to examine Italian consumer preferences for extra virgin olive oil (EVOO) enriched with vitamins and to analyze the key drivers that affect consumer choices for this product. Specifically, we assessed consumers’ intention to purchase the enriched product compared to the conventional one. The methodology adopted inferential and multivariate statistical techniques: (1) exploratory factor analysis (EFA), (2) ordinary least squares regression (OLS) and (3) non-hierarchical clustering. This study appears to be the first research project related to exploring consumers’ interest in an extra virgin olive oil enhanced with vitamins, thereby providing preliminary indications. The main results represent a significant starting point for the development of new marketing strategies for the food industry
The EU Nature Restoration Law (NRL) and the Common Agricultural Policy (CAP): State of the Art and Future Challenges for Italian Water Resources
Full text linkAmong its various targets on restoring natural habitats and ecosystems in the EU, the recently adopted Nature Restoration Law (NRL) introduces ambitious targets for restoring surface water bodies (SWBs) as well. Simultaneously, the Italian CAP Strategic Plan for the implementation of the Common Agricultural Policy 2023–2027 has been designed to enhance sustainable agricultural practices, including water resource management. This paper provides a comparative analysis of the synergies, gaps, and challenges between these two regulatory frameworks, focusing on sustainable water use in Italian agriculture. A two-level comparative matrix methodology is employed to evaluate the alignment between the NRL’s objectives for freshwater ecosystems and the measures taken by the Italian CAP Strategic Plan on water resources. The results highlight key areas of convergence, existing shortcomings, and necessary steps for aligning Italian agricultural policies with the EU’s water restoration goals. The findings offer insights for policymakers, researchers, and stakeholders engaged in water governance, biodiversity conservation, and agricultural sustainability
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
