Rilocalizzazione di attività produttive su un territorio. Analisi preliminare di sostenibilità di una filiera lana-carne ovina
No full textThe objective of this article is to present the preliminary results of an environmental
sustainability study associated with the “Autoctonie” project, promoted in
2018 by the Fashion and Agribusiness Sections of Confindustria Chieti Pescara
(Abruzzo, Italy). The objective is to promote the revitalization of a short ovine supply
chain based on wool and meat produced in the region. The supply chain will be
analyzed by referring to two scenarios, elaborated according to Industrial Ecology
approaches: a current one, in which the companies involved in the project are forced
to purchase raw materials from foreign markets and a prospective one in which
through the maximization of synergies deriving from a local supply chain, we can
promote the use of products, by-products and derivatives of sheep breeding (in particular
wool and meat, but also milk and leather) by local companies
Impatti ambientali delle perforazioni petrolifere: il contributo della "scarpa di cementazione"
No full textIl presente articolo affronta, in una prospettiva di ciclo di vita, la valutazione degli impatti ambientali di un manufatto tipico del processo di estrazione del petrolio, la scarpa di cementazione, o float shoe, che costituisce uno degli elementi utilizzati nella cementazione dei pozzi dopo la loro perforazione. L’analisi si basa su un caso studio di un’azienda leader del settore. I dati primari raccolti riguardano la produzione di una scarpa di cementazione -float shoe- in una prospettiva cradle to gate e sono stati elaborati tramite il software CCaLC2 al fine di identificare l’impatto ambientale complessivo e il contributo delle fasi produttive. I risultati ottenuti sono utili sia al completamento degli studi relativi alla valutazione degli impatti del ciclo di vita del petrolio in un segmento della filiera ancora poco investigato, che a fornire agli operatori del settore elementi utili al miglioramento delle performance ambientali del componente in esame
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
Local government initiatives to promote industrial development. The case of Abruzzo Region
No full textThe transition to sustainable industrial systems is one of the cornerstones of European Union policy to develop a competitive
economy, that are progressively translating into a series of regulatory and other initiatives, both at national and local level. Although these
initiatives are now numerous, few have been able to make the most of the advantages of a “bottom-up” collaborative approach, capable of
synergistically exploiting the advantages deriving from incentives, financing and tax relief that European policies, at the local level, have
promoted in the last few years. In this article, the “Carta di Pescara” initiative will be presented and analyzed. It is a programmatic
document of the Abruzzo Region, co-designed together with the business and academic world, which incorporates the guidelines of European
policies on environmental sustainability applied to industry. The article describes the inspiring principles of this governance tool, the choice of
stakeholders, the structuring process, the selection and definition criteria of the rankings, the rewarding mechanisms. Finally, the first results
will be exposed, some statistics on the current members and the potential benefits as well as the criticalities of this initiative
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
Assessing the social sustainability of circular economy practices: Industry perspectives from Italy and the Netherlands
Full text linkDespite the frequent association of circular economy (CE) with sustainability, most CE practices have yet to prove they actually contribute to achieving the Sustainable Development Goals (SDGs), and social aspects in particular. To attain the consensually established targets in the SDG framework, it is vital to assess the impact of CE practices. As most of these practices are carried out in a network of actors, sustainability assessment approaches from the fields of industrial ecology and supply chain management are particularly suitable. However, both fields are known for their limited inclusion of the social dimension. While scholars have already started to explore the assessment of social sustainability within the context of CE practices, little is known about the perspectives and experiences concerning social assessment of businesses actively involved with CE. Thus, the authors conducted 43 semi-structured interviews with frontrunner companies engaged with CE in Italy and the Netherlands to obtain a better picture of (1) how these firms view the importance of the social dimension as part of the assessment of CE practices, (2) what the barriers to conducting social assessment are, and (3) whether they have experience with assessing social sustainability aspects within their companies and supply chains. Through a thematic analysis, it was found that most companies deem the social dimension to be relevant to CE assessment and either consider it an integral part of CE or of sustainability. However, a majority of the firms did not conduct any type of social assessment. Most companies which implemented assessments did so in a qualitative manner or used industry-based sustainability indicator frameworks. Notwithstanding the prevalence of social life cycle assessment in the academic realm, almost all interviewees mentioned barriers to its application related to its complexity and the lack of a standardised approach. © 2021 Institution of Chemical Engineer
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
