PDOs’ role in reassuring consumers: the “Parmigiano Reggiano Terremotato” case
No full textThe earthquake swarm that shook the Emilia Romagna (Italy) region in May 2012 caused 26 deaths and diffuse economic damage in the traditional production area of Parmigiano-Reggiano Protected Designation of Origin (PDO), including several dairies’ warehouses where the cheese is produced and aged. It has been estimated that the loss to the Parmigiano-Reggiano producers exceeded 150 million euros. The broad mobilization to help the stricken people revealed the “social embeddedness” of this specific food, giving rise to the sale 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 new concept of sustainability is explored, departing from the ability of the PDO brand name to reassure consumers’ trust. A preliminary focus group was formed and a survey on 200 consumers was carried out for this purpose; data were collected during 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 were 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 percent of the variance in intention to purchase PR-T in the future and 32 percent of the variance in 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 affected by food scares, past behaviour and educational level. The PDO granted to Parmigiano Reggiano cheese played a powerful role in reassuring consumers, avoiding the “worst-case scenario”(market crisis). This seems interesting since PDO may make food chains resilient in front of adverse events with a probable economic impact, maintaining the trust and providing food chain sustainability. Prices of Parmigiano-Reggiano remained stable, and both the producers and the Consortium played an active role. These empirical findings also provide evidence of the solidarity aspects of collective purchases of Parmigiano-Reggiano in the aftermath of the 2012 earthquake swarm, as well as the importance of increasing people’s capability and trust to effectively reach the goal of facing alarming food scares
Deep carbon cycle through five reactions
Full text linkWhat are the key reactions driving the global carbon cycle in Earth, the only known habitable planet in the solar system? And how do chemical reactions govern the transformation and movement of carbon? The special collection “Earth in five reactions - A deep carbon perspective” features review articles synthesizing knowledge and findings on the role of carbon- related reactions in Earth's dynamics and evolution. These integrative studies identify gaps in our current understanding and establish new frontiers to motivate and guide future research in deep carbon science. The collection also includes original experimental and theoretical investigations of carbon-bearing phases and the impact of chemical and polymorphic reactions on Earth's deep

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
