    May trust and solidarity defy food scares? The case of Parmigiano-Reggiano PDO sales in the aftermath of natural disaster

    No full text
    Purpose: A major earthquake and aftershocks have hit the North-East part of Italy in May 2012, and caused 26 deaths and diffuse economic damage in the localised agri-food system (LAFS) of Parmigiano-Reggiano protected designation of origin (PDO), including several dairy warehouses. In the broad mobilization to help the stricken people, the LAFS actors played a primary role, giving rise to the sales of “Parmigiano-Reggiano damaged by the earthquake” (PR-T). The purpose of this paper is to investigate the main determinants of PR-T purchasing using the theory of planned behaviour (TPB). Design/methodology/approach: A survey on 200 consumers was performed. Data were collected with face-to-face interviews in stores and markets where the PR-T has been sold, and analyzed by structural equation modelling. Findings: The TPB model predictors accounted for 52 per cent of the variance of intentions to purchase PR-T in the future and 21 per cent of the variance of behaviour. Perceived behavioural control is the main predictor of intention and behaviour, indicating that making easier the access to key resources and increasing people’s capability seems a major aspect to reach the intended goals. Trust in producers and retailers communication, positive image of the PDO label, sense of belonging to the region of origin and socio-demographics, i.e. age and educational levels, are correlated with intention and behaviour. The food scare flare up in the media was not a reason impeding purchasing PR-T. Originality/value: These findings show the solidarity aspects underlying the collective purchases of PR-T in the aftermath of the 2012 earthquake waves, and the importance of increasing people’s capability and trust to reach the goal of facing dreadful food scares effectively

    Food purchase for natural disaster relief: the case of Parmigiano-Reggiano sales in the aftermath of the 2012 earthquake waves

    The May 2012 earthquake waves shaking the North-East part of Italy have caused 26 deaths and diffuse economic damage in the traditional production area of Parmigiano-Reggiano PDO, including several dairies warehouses where the cheese is produced and aged. It has been estimated that losses to the Parmigiano-Reggiano system exceeded 150 millions Euro. In the broad mobilization to help the stricken people, the agri-food system played a primary role, giving rise to the sales of “Parmigiano-Reggiano damaged by earthquake” (PR-T). This paper aims to investigate the main determinants of PR-T purchasing using the theory of planned behaviour (TPB) as a conceptual framework. A preliminary focus group and a survey on 200 consumers were performed for this purpose; data were collected with face-to-face interviews in stores and markets where the PR-T has been sold. The relative importance of attitude, descriptive norms and perceived behavioural control (PBC) in influencing the intention to purchase PR-T and the behaviour itself where investigated. Other concepts were added to the analysis, such as formal and informal trust, moral attitude, PDO perception, sense of belonging to the region, and other socio-economic variables. The revised TPB model predictors accounted for 70% of the variance of intentions to purchase PR-T in the future and 32% of the variance of behaviour. PBC, trust in formal communication sources and PDO quality warranty are the main predictors of intentions. Behaviour is positively affected by descriptive norms, sense of belonging, age and intentions, and negatively determined by food scare, past behaviour and educational level. These empirical findings provide evidence of the solidarity aspects of collective purchases of Parmigiano-Reggiano in the aftermath of the 2012 earthquake waves, as well as the importance of increasing people’s capability and trust to effectively reach the goal of facing dreadful food scares

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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 link
    We 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
