The effects of the covid-19 pandemic on the mass market retailing of wine in Italy
Full text linkThe purpose of this study was to provide a detailed framework of wine purchases in supermarkets during the COVID-19 pandemic. The unexpected diffusion of the virus and the restrictions imposed in Italy to prevent its spread have significantly affected the food purchasing habits of consumers. By analyzing the scanner data of the wine sales in the Italian mass market retail channel, this study was intended to show whether and how the dynamics triggered by the pandemic have modified the overall value and type of wine purchases, focusing on prices, formats, and promo-tional sales. In particular, this study explores sales in two separate periods, namely March–April (the “lockdown”, with general compulsory closing and severe restrictions) and June–July 2020 (the “post-lockdown”, in which some limitations were no longer effective). The analysis of wine sales during lockdown and post-lockdown and the study of the variations compared to the sales of the previous years showed some significant changes in purchase behavior. The results could provide managers, researchers, and policy makers with extensive insights into the purchasing patterns of consumers during this unprecedented time and reveal trends that may characterize the structure of the future wine demand
Effect of executional greenwashing on market share of food products: An empirical study on green-coloured packaging
No full textGreenwashing refers to the strategies adopted by some manufacturers to convey environmentally friendly production methods using claims, green-coloured packaging, and nature-evoking images without reflecting an actual environmental commitment. This phenomenon constitutes a threat to the development of an environmentally and economically sustainable market. Evaluating the impacts of these practices on the purchase behaviour of food consumers is crucial to provide manufacturers, retailers, and policymakers with meaningful guidance. This study aims to analyse the effect of the green-coloured packaging of two chocolate bars on consumers' choices. We implemented an online choice experiment with 737 Italian consumers following a between-subject approach. In the control treatment, we used the original packaging of both chocolate bars, whereas, in the other two treatments, we coloured the packaging of one chocolate bar green and retained the other's original colour. We estimated how the market shares changed when the packaging was greenwashed and segmented our sample according to respondents' attitudinal traits. Our findings demonstrate that greenwashing food products can potentially increase their market share compared to ordinary food, thus supporting the concerns of consumer organisations. However, the present study was inconclusive in identifying a profile of consumers who are most likely to be taken in by greenwashing. In the conclusion, we provide practical implications for policymakers, industry, and retailers for counteracting greenwashing
Determinants of online food purchasing: The impact of socio-demographic and situational factors
No full textThe amount of food sold online is increasing, but it accounts for a small share of total e-commerce. In this study, we investigate the factors that influence individuals' likelihood to buy food online. Applying a logit model to a sample of 34,488 respondents who participated in the Italian National Institute of Statistics multipurpose survey ‘Aspects of Italian Daily Life’, we explore the effects of socio-demographics and situational factors. We found that the food-online consumer is likely to be a young, well-educated, female, living in a small family, with a very good or adequate overall economic condition. Among situational factors, working time, being obese, having health problems, and practising a sport regularly positively affect the probability to buy food online. Surprisingly, distance from brick-and-mortar stores and car possession are not predictors of online shopping. These findings can support marketers and retailers in defining their marketing strategies and enhance the knowledge of this emerging food market
Using Electromagnetic Time Reversal Similarity Metric to Locate Lightning-Originated Flashovers on Overhead Transmission Lines
No full textThe paper presents a method to locate flashovers resulting from direct lightning strikes to overhead transmission lines. The method exploits the electromagnetic time-reversal theory and uses the cross-correlation between the flashover-originated transient current observed in the direct time and the transverse branch currents in the reversed time at the guessed flashover locations as a similarity metric to identify the location of the flashover. The performance of the similarity metric is numerically illustrated using two simulation case studies associated with a shielding failure and a back-flashover
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
