A methodological approach for assessing businness investments in renewable resources from a circular economy perspective
No full textIn this paper, we have analyzed a feasibility project for the realization of a biogas plant at a company in the viticulture sector located in south-central Sicily. Using engineering formulas, we identified the electrical power that the plant could produce using waste products created by the vineyard itself, examined the new and interesting opportunities that have arisen with the encouragement and development of biogas production in Italy, and then assessed the economic feasibility of the investment itself, considering an investment scheme of total capital self-financing.The possibility of using wastes from wine production comes from an in-depth study of the circular economy, that is, an economic system designed to regenerate on its own; indeed, in the circular economy, every waste product becomes a resource, and some resources can be taken from one production scheme and used in another without being discarded.The concept of circular economy is based on the ability to recover onsite resources that are still circulating (overproduction, waste) instead of importing them from the outside. Recovering these substances creates sustainable agriculture, preserves soil fertility thanks to reconstructed biodiversity, and also helps locate proper uses for refuse and organic waste products
Marketing Strategies the Agrifood Products
No full textAgri-food production represents the specific character of an area. Food and wine culture derives from this production and is a distinctive element and an important asset for the area, with important repercussions in other sectors of the economy: industry, commerce, tourism, research. Agri-food heritage is constantly evolving, and there are frequent cases of imitation products sold in non-European markets. To combat this phenomenon, the European Union has sought to reduce this risk by granting quality marks to products that demonstrate specific links to their places of origin. The objective of this work is to analyze the motivations, benefits, and costs associated with the recognition of a local product by a Slow Food Presidium, considering both individual companies and local production systems. The research shows that Slow Food Presidia initiate processes of regeneration for the "value" of food products and play a critical role in the success of individual companies, in particular, but also for the local area more generally
Company Competitiveness as a Variable Success Strategy for the Territory and the Environment
Full text linkSupporting the fortunes of the Made in Italy agri-food brand are the best quality products which can be found throughout the Italian territory and which, in many cases, derive from Southern Italy, with a particularly interesting role assumed by Campania and Sicily.The Sicily Region boasts a varied and peculiar food and wine heritage, especially from a qualitative point of view, the Born in Sicily brand, made with excellent raw materials which constitute and support the development of important production lines within the agro-industrial sector.Among the most important food industries in Italy and on the island, there are some operating in the confectionery industry. Today the fast-growing confectionery industry contributes a great deal to the agri-food system.This study analyzes the agri-food system both in Italy and Sicily, highlighting the main sectors which contribute to make the Made in Italy brand competitive around the world and how companies have succeeded in starting up some interesting internationalization processes.This the reason why a specific case regarding a Sicilian confectionery industry is examined so as to understand how it was able to create such a successful innovative product, establishing itself on both the national and international market.The results show that entrepreneurial skills contribute a great deal to creating business competitiveness and territorial development
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
