The effect of hedonic and eudaimonic happiness in driving altruistic food choices
No full textThis study investigates whether individual happiness affects prosocial behavior in food choices. We considered two distinct dimensions of happiness: hedonic and eudaimonic. The hedonic component is focused on pleasure, joy, and immediate gratification, while the eudaimonic aspect is related to a sense of purpose in life, personal growth, and the fulfillment of individual aspirations. We conducted a discrete choice experiment to assess if happy people are more prone to altruistic choices when buying food. The results indicate that individual happiness exerts distinct effects according to its two dimensions, eudaimonia and hedonism. We found that happiness influences the demand for ethical foods, whereas it exerts a detrimental effect on preferences for food with environmental labels
Stakeholder perspectives on emerging models of short food supply chains: a mixed-methods investigation on the 'Km Zero Newsstand' case in Italy
Full text linkThe transition of food systems towards more sustainable organizational models is increasingly positioning Short Food Supply Chains as a key channel to value the specific attributes of local products, while also meeting the growing demand for diversified consumption based on both socio-economic and socio-cultural drivers. The aim of this paper is to offer new insights into evolutionary multi-stakeholder organization strategies within SFSCs, analysing drivers and barriers to their adoption, and investigate consumer acceptance of such new models. We draw upon the case study of the Km0 Newsstand project, an initiative launched to enhance and promote the biocultural heritage of the Tuscany region through the direct sale of traditional agricultural products, local food specialities and crafts, as well as related services in newsstands. We adopted a mixed-methods approach to conduct an in-depth analysis of this innovative SFSC model. To investigate the perspective of producers and retailers, we developed a Strengths, Weaknesses, Opportunities, and Threats analysis and also a Social Business Model Canvas of this newly designed business model by collecting and analysing existing documents and carrying out in-depth interviews with key informants. On the demand side, we implemented an online survey (N = 1000) to explore the factors influencing the intention of consumers to use the Km0 Newsstand services, along with potential drivers and barriers for their purchasing behaviour. Results show how the model ensures a balance between financial sustainability and the mission of promoting sustainable local consumption while fostering economic, social, and environmental benefits for all stakeholders involved
Triggering Ethical Food Choices Through Identity Labelling: Evidence From a Field Experiment
Full text linkThe importance of social and ethical communication as a regulatory instrument to nudge more sustainable consumption patterns is advocated at the European and global policy levels. Little is known about the effectiveness of identity labelling, an innovative form of information provisioning leveraging the individual self-perception to encourage virtuous behaviours. We conducted a framed field experiment using the Becker-DeGroot-Marschak (BDM) mechanism to investigate consumers' responses to social identity labelling, that is, identity labelling hinging upon sensitivity to social issues. This study is the first application to test social identity labelling in an incentive-compatible food experiment. The results show that overall consumers are indifferent to the presence of social identity labelling, as their willingness to pay for an ethical product does not increase when this information tool is applied. However, environmentally conscious consumers exhibit a premium for products with social identity claims, while social consciousness shows no significant effect. Moreover, the effectiveness of identity labels is not mediated by personality traits conceptualised as the Big Five
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
