Italian Consumers and Cultured Meat: Risk, Preferences, and Politics
No full textCultured meat is produced in vitro, and it is presented as a method able to reduce the controversial effect of farmed meat, on the environment and animal welfare. To speed up the shift to sustainable food systems with such innovation, it is necessary to analyze consumer preferences and attitudes towards this novel food. Attention should be paid specifically to the relevant role of consumers’ political affiliation, risk attitudes, and perceptions of cultured meat, as compared to farmed meat, on consumers’ acceptance of this novel food. This study investigates these aspects using a representative sample of the Italian population in terms of gender, age, and region, and a balance across education levels. Data collection was conducted via a digital platform in December 2023. The sample included 800 participants. The data were analyzed using an ordered logistic regression model, with marginal effects reported for clarity. Results show that as the level of acceptance increases, consumers’ preferences depend heavily on their’ perceptions of cultured meat as compared to farmed meat. Our research offers valuable insights into consumers’ views related to cultured meat. Additionally, it provides practical guidance to promote cultured meat using an evidence-based strategy
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
Hedonic-vs. health-based approach to food: An explorative study of extrinsic attributes importance among French and Italian consumers
No full textUnderstanding the psychological and behavioral factors that influence consumers’ food choices is essential for public health and provides a crucial foundation for interventions aimed at promoting healthier diets. Research has shown that food decisions are significantly shaped by both hedonic preferences and health considerations. However, how consumers with different approaches to food prioritize various food attributes has yet to be thoroughly explored. This paper aims to address this gap by exploring how hedonic and healthy eating behavior vary in the importance given to extrinsic attributes. A cross-sectional survey was conducted among nationally representative samples of consumers in Italy and France (N = 2000). Consumer perceptions of six food attributes were analyzed using ordered logistic regression to examine the influence of hedonic and health-conscious eating behaviors. Results showed that respondents following a more hedonic approach to food prioritize food attributes differently based on their cultural heritage, with notable distinctions between French and Italian consumers. French consumers tend to perceive a conflict between hedonic preferences and sustainability attributes. In contrast, Italian consumers do not exhibit these conflicts. Consumers who pay more attention to health when choosing food also tend to give more importance to all extrinsic attributes. This pattern was observed in both Italian and French samples, suggesting that health-conscious individuals are more likely to make food decisions based on information and careful evaluation of product characteristics
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
